Clawback Policy
Total Rewards, Human Resources


1.0 PURPOSE AND APPLICATION
1.1
Purpose
This clawback policy is designed to allow Sun Life to reclaim or “claw back” incentive compensation in situations where employees received excessive or undeserved compensation. This includes instances of Misconduct (all employees) or financial restatements (Executives described in this policy).
1.2
Application
This Policy is an Enterprise Policy. It applies to all current and former employees in the case of Misconduct. In the case of financial restatements, it applies to "Executive Officers", which are Executive Team Members of the Company, and any other individuals determined by the Board in its sole discretion to be subject to this Policy in the case of financial restatements.
This policy does not apply to Joint Ventures and Joint Ventures under management control.
2.0 POLICY
2.1 All current and former employees covered by this Policy are required upon demand by the Board to repay any or all Incentive Compensation received or realized by such employee during the three completed fiscal years immediately prior to a determination by the Board that the employee engaged in Misconduct.
2.2 All Executive Officers are required upon demand by the Board to repay any excess Incentive Compensation received or realized by them during the three completed fiscal years immediately preceding the relevant Restatement Date (as well as during any transition period specified in Rule 10D-1(b)(1)(i)(D) under the Exchange Act), other than any Incentive Compensation that was received prior to such Executive Officer’s service as an Executive Officer or prior to the effective date of the U.S. Stock Exchange rules implementing Rule 10D-1 under the Exchange Act, if the Incentive Compensation received or realized by such Executive Officer during such period would have been less had the results of the Accounting Restatement been known (such excess Incentive Compensation, as computed without regard to any taxes paid thereon, the “Erroneously Awarded Compensation”).
2


image_0a.jpg                                                    
Clawback Policy
Total Rewards, Human Resources

2.3 For purposes of this Clawback Policy, “Accounting Restatement” means any accounting restatement of the Company’s financial statements due to material noncompliance with any financial reporting requirement under the securities laws, including (i) a restatement required to correct a material error in previously-issued financial statements and/or (ii) a restatement required in the current period merely to avoid material misstatements resulting from either an uncorrected error or the recognition of a corrected error in the current period, which may include a restatement to avoid cumulative effects of an error over several reporting periods. Clawbacks do not apply to out-of-period adjustments that are not Accounting Restatements or to retrospective applications of changes in accounting principles, retrospective reclassifications due to discontinued operations or other retrospective revisions or adjustments that do not represent error corrections.
2.4 Erroneously Awarded Compensation will be “clawed back” (i.e., recovered from, or repaid by, the applicable Executive Officer) regardless of whether the Executive Officer was party to or aware of the misstatement, and applies to former Executive Officers who were employed in that capacity during the above three-fiscal-year period (or relevant transition period) (such recovery or repayment of Erroneously Awarded Compensation, a “Clawback”). Neither Executive Officers, former Executive Officers, nor the Company may insure or indemnify Executive Officers against a Clawback. The Company may decide not to attempt to recover funds in situations only as allowable under applicable legislation, in particular the Exchange Act (as discussed further below). If the Board determines that an Executive Officer received any Erroneously Awarded Compensation in connection with an Accounting Restatement, the Board shall, reasonably promptly after the Restatement Date, seek recoupment from such Executive Officer of all such Erroneously Awarded Compensation, subject to the Impracticality Exceptions.
2.5 A Clawback will not be triggered by the following changes to the Company’s financial statements: retrospective application of a change in accounting principle, retrospective revision to reportable segment information due to a change in organization structure, retrospective reclassification due to a discontinued operation, retrospective application of a change in reporting entity, or retrospective adjustment to provisional amounts in connection with a prior business combination and retrospective revision for stock splits, reverse stock splits, stock dividends or other changes to the capital structure.

Clawback Policy
Total Rewards, Human Resources

2.6 For Incentive Compensation based on the Company’s stock price or total shareholder return, where the amount of Erroneously Awarded Compensation is not subject to mathematical recalculation directly from the information in an Accounting Restatement: (i) the amount of Erroneously Awarded Compensation must be based on a reasonable estimate of the effect of the Accounting Restatement on the Company’s stock price or total shareholder return upon which the Incentive Compensation was received; and (ii) the Company must maintain documentation of the determination of that reasonable estimate and provide such documentation to the applicable U.S. Stock Exchange. Reference is further made to Rule 10D-1(b)(1)(iii) under the Exchange Act and the rules of the applicable U.S. Stock Exchange used for calculating Erroneously Awarded Compensation.
2.7 Prior to making a demand for payment related to financial restatements, the Board will conduct an appropriate investigation of relevant facts in compliance with relevant regulations in Canada, the United States or other competent jurisdiction.
2.8 The Board may retain a financial advisor to provide an opinion on the fair market value of a common share of Sun Life Financial Inc. on the date that a payment of Incentive Compensation was calculated or that an option was exercised had the Misconduct and/or Accounting Restatement not occurred.
2.9 The Board may take into account a variety of factors in its sole discretion in determining whether to demand repayment for Misconduct.
2.10 The Board shall not, under this Clawback Policy, demand payment of an amount in excess of (i) the pre-tax amount of Incentive Compensation received or realized by the Executive Officer or former Executive Officer in situations of Misconduct or (ii) the amount of Erroneously Awarded Compensation received or realized by the Executive Officer or former Executive Officer attributable to an Accounting Restatement.
2.11 A demand for payment under this Clawback Policy shall be on such terms as the Board specifies in compliance with applicable legislation and related regulations and rules (including the U.S. Clawback Rules).
2.12 The Company will take any action authorized by law to enforce a demand for repayment by the Board that is not promptly complied with by a current or former employee.

Clawback Policy
Total Rewards, Human Resources

2.13 This Clawback Policy does not in any way detract from the requirements of section 304 of the Sarbanes-Oxley Act of 2002 and does not prevent the Company from taking any other appropriate action against an employee who is determined to have engaged in Misconduct, up to and including termination of employment.
2.14 The Board will determine, in its sole discretion, the method for recouping amounts hereunder which may include, without limitation:
2.14.1 • requiring reimbursement of cash amounts previously paid (on a pre-tax basis);
2.14.2 • seeking recovery of any gain realized on the vesting, exercise, settlement, sale, transfer, or other disposition of any Incentive Compensation;
2.14.3 • offsetting the amount of the Erroneously Awarded Compensation, or Incentive Compensation, as applicable, otherwise owed by the Company to the Executive Officer as of the Restatement Date;
2.14.4 • cancelling outstanding vested or unvested Incentive Compensation;
2.14.5 • taking any other remedial and recovery action permitted by law, as determined by the Board; or
2.14.6 • any combination of the foregoing, as determined by the Board.
2.15 The Company must recover any Erroneously Awarded Compensation unless the Management Resources Committee of the Board determines that any of the impracticality exceptions set forth in Rule 10D-1(b)(1)(iv) under the Exchange Act and/or the rules of the applicable U.S. Stock Exchange are available, as set forth below (the “Impracticality Exceptions”):
2.15.1 • The direct expense paid to a third party to assist in enforcing this Clawback Policy would exceed the amount of Erroneously Awarded Compensation to be recovered. Before concluding that it would be impracticable to recover any amount of Erroneously Awarded Compensation pursuant to this clause, the Company must make a reasonable attempt to recover such Erroneously Awarded Compensation, document (in writing) such reasonable attempt(s) to recover and provide that documentation to the applicable U.S. Stock Exchange
2.15.2 • Recovery would violate applicable Canadian law where that law was adopted prior to November 28, 2022.
5


image_0a.jpg                                                    
Clawback Policy
Total Rewards, Human Resources

2.15.3 • Recovery would likely cause an otherwise tax-qualified retirement plan of the Company, under which benefits are broadly available to employees of the Company, to fail to meet the requirements of 26 U.S.C. 401(a)(13) or 26 U.S.C. 411(a) and regulations thereunder.
2.16 The Company’s obligation to recover Erroneously Awarded Compensation is not dependent on if or when the restated financial statements for the Accounting Restatement have been filed.
2.17 Recoupment of Erroneously Awarded Compensation under section 2.2 of this Clawback Policy is made on a “no fault” basis, without regard to whether any misconduct occurred or whether any Executive Officer is responsible for the noncompliance that resulted in the Accounting Restatement.
2.18 This Clawback Policy is qualified by reference to applicable SEC rules (including Rule 10D-1 under the Exchange Act) and, when adopted, the rules of the applicable U.S. Stock Exchange (collectively, the “U.S. Clawback Rules”). To the extent there is a conflict between this Clawback Policy and the U.S. Clawback Rules, or any interpretive question arises hereunder, the U.S. Clawback Rules will prevail.

Management's Discussion and Analysis
February 7, 2024

A. How We Report Our Results

Sun Life is a leading international financial services organization providing asset management, wealth, insurance and health solutions to individual and institutional Clients. Sun Life has operations in a number of markets worldwide, including Canada, the United States, the United Kingdom, Ireland, Hong Kong, the Philippines, Japan, Indonesia, India, China, Australia, Singapore, Vietnam, Malaysia and Bermuda. As of December 31, 2023, Sun Life had total assets under management ("AUM") of $1.40 trillion. For more information please visit www.sunlife.com.

Sun Life Financial Inc. trades on the Toronto (TSX), New York (NYSE) and Philippine (PSE) stock exchanges under the ticker symbol SLF.

Sun Life Financial Inc. ("SLF Inc.") is a publicly traded company domiciled in Canada and is the holding company of Sun Life Assurance Company of Canada ("Sun Life Assurance"). In this management's discussion and analysis ("MD&A"), SLF Inc., its subsidiaries and, where applicable, its joint ventures and associates are collectively referred to as "the Company", "Sun Life", "we", "our", and "us". Unless otherwise indicated, all information in this MD&A is presented as at and for the year ended December 31, 2023 and the information contained in this document is in Canadian dollars. Amounts in this document are impacted by rounding.

Where information at and for the year ended December 31, 2023 is not available, information available for the latest period before December 31, 2023 is used. Except where otherwise noted, financial information is presented in accordance with International Financial Reporting Standards ("IFRS") and the accounting requirements of the Office of the Superintendent of Financial Institutions ("OSFI"). Reported net income (loss) refers to Common shareholders' net income (loss) determined in accordance with IFRS.

We manage our operations and report our financial results in five business segments: Asset Management, Canada, United States ("U.S."), Asia, and Corporate. Information concerning these segments is included in our annual and interim consolidated financial statements and accompanying notes ("Annual Consolidated Financial Statements" and "Interim Consolidated Financial Statements", respectively, and "Consolidated Financial Statements" collectively), and this MD&A document.

On January 1, 2023 we adopted IFRS 17 Insurance Contracts ("IFRS 17"), which replaces IFRS 4 Insurance Contracts ("IFRS 4"). IFRS 17 establishes the principles for the recognition, measurement, presentation, and disclosure of insurance contracts. On January 1, 2023, we also adopted IFRS 9 Financial Instruments ("IFRS 9"), which replaces IAS 39 Financial Instruments: Recognition and Measurement ("IAS 39"). The nature and effects of the key changes in our critical accounting policies and estimated impacts from the adoption of the new standards are summarized in section N - Accounting and Control Matters in this document. For more information including the measurement and classification of opening balances, refer to Note 2 of our 2023 Annual Consolidated Financial Statements.

Note to Readers: 2022 Restated Results on Adoption of IFRS 17 and IFRS 9
2022 results have been restated for the adoption of IFRS 17 and the related IFRS 9 classification overlay (“the new standards”). The restated results may not be fully representative of our future earnings profile, as we were not managing our asset and liability portfolios under the new standards. The majority of the actions taken to re-balance asset portfolios and transition asset-liability management execution to an IFRS 17 basis occurred in Q1'23. Accordingly, analysis based on 2022 comparative results may not necessarily be indicative of future trends, and should be interpreted with this context. Using sensitivities to analyze the outlook for market risk and related impacts (e.g., interest rate sensitivities) will be more representative starting with the sensitivities disclosed for Q1’23 and onward in section K - Risk Management in this document and section I - Risk Management in each quarter's respective interim MD&A document. Certain 2022 restated results and 2023 interim results in the Drivers of Earnings and CSM Movement Analysis were refined to more accurately reflect how management views the business.
2 December 31, 2023 Sun Life Financial Inc. MANAGEMENT'S DISCUSSION & ANALYSIS Sun Life has a diversified mix of businesses and our earnings by business type supports the analysis of our results:


Underlying net income by Business Types
•Wealth & asset management: Sun Life’s wealth & asset management businesses generate fee income and/or spread on investment products.
•Group - Health & Protection: Group businesses provide health and protection benefits to employer and government plan members. The products generally have shorter-term coverage periods, and more frequent repricing. The revenues are driven by premiums for coverage provided as well as fee-based earnings (i.e., Administrative Services Only plans, and dental fees).
•Individual - Protection: Generally, individual protection businesses have a longer-term profitability profile and are more sensitive to experience trends. The premiums include a margin for providing protection and are invested to earn a return over the expected amounts required to fulfill insurance liabilities.

The following provides an overview of the business types in Sun Life's business segments/business groups:

businesstype-englishfeb2upa.jpg


1. Use of Non-IFRS Financial Measures
We report certain financial information using non-IFRS financial measures, as we believe that these measures provide information that is useful to investors in understanding our performance and facilitate a comparison of our quarterly and full year results from period to period. These non-IFRS financial measures do not have any standardized meaning and may not be comparable with similar measures used by other companies. For certain non-IFRS financial measures, there are no directly comparable amounts under IFRS. These non-IFRS financial measures should not be viewed in isolation from or as alternatives to measures of financial performance determined in accordance with IFRS. Additional information concerning non-IFRS financial measures and, if applicable, reconciliations to the closest IFRS measures are available in section M - Non-IFRS Financial Measures in this document and the Supplementary Financial Information package on www.sunlife.com under Investors - Financial results and reports.

2. Forward-looking Statements
Certain statements in this document are forward-looking statements within the meaning of certain securities laws, including the "safe harbour" provisions of the United States Private Securities Litigation Reform Act of 1995 and applicable Canadian securities legislation. Additional information concerning forward-looking statements and important risk factors that could cause our assumptions, estimates, expectations and projections to be inaccurate and our actual results or events to differ materially from those expressed in or implied by such forward-looking statements can be found in section P - Forward-looking Statements in this document.

3. Additional Information
Additional information about SLF Inc. can be found in the Consolidated Financial Statements, the annual and interim MD&A, and SLF Inc.'s Annual Information Form ("AIF") for the year ended December 31, 2023. These documents are filed with securities regulators in Canada and are available at www.sedarplus.ca. SLF Inc.'s Annual Consolidated Financial Statements, annual MD&A and AIF are filed with the United States Securities and Exchange Commission ("SEC") in SLF Inc.'s annual report on Form 40-F and SLF Inc.'s interim MD&A and Interim Consolidated Financial Statements are furnished to the SEC on Form 6-Ks and are available at www.sec.gov.

B. Overview

Sun Life is a leading international financial services organization providing a diverse range of asset management, wealth, insurance, and health solutions to individual and institutional Clients. We have four business pillars: Asset Management, Canada, U.S. and Asia.


1. Strategy
Our strategy places the Client at the centre of everything we do. Our enterprise strategy, as described below, reflects our priorities and our diversified business mix. We believe by effectively executing on our strategy, we can fulfill our Purpose, create a positive impact for our Clients, and achieve our goal to be a leader in each of our four pillars.
q423placemata.jpg
Purpose and Ambition
Our Purpose is to help our Clients achieve lifetime financial security and live healthier lives.

We seek to provide outstanding value and impact for our Clients in three ways:

Driving positive financial actions by:
•Helping Clients build and protect their wealth.
•Providing quality products and solutions that meet the needs of our Clients.
•Delivering timely and expert advice through consistently superior Client experiences.

Delivering solid long-term Client investment returns by:
•Leveraging our collective expertise to make better investment decisions.
•Sourcing broad investment capabilities to serve global Client needs.
•Actively engaging with our Clients to think and act sustainably.

Driving positive health actions by:
•Being a trusted provider of a broad range of health and wellness coverages.
•Helping Clients access, navigate, manage, and receive the care they need.
•Improving health outcomes, including physical and mental well-being, by providing health solutions.

Our Ambition is "to be one of the best asset management and insurance companies in the world". We aim to achieve our ambition by maintaining our balanced business mix and leading positions across our pillars, delivering on our Purpose and Client Impact strategy, and focusing on strong execution to meet our medium-term financial objectives(1)(2):
•Underlying Earnings Per Share ("EPS") growth: 8-10%.
•Underlying Return on Equity ("ROE"): 18%+.
•Underlying Dividend Payout Ratio: 40%-50%.

(1)For more information about our medium-term financial objectives, see section B - Overview - 2 - Financial Objectives in this document. Underlying EPS, underlying ROE and underlying dividend payout ratio are Non-IFRS financial measures. See section M - Non-IFRS Financial Measures in this document.
(2)Our medium-term financial objective for underlying ROE changed to 18%+ following the adoption of IFRS 17 and IFRS 9, an increase from 16%+ prior to transition. Our medium-term financial objectives remain consistent for underlying earnings per share and underlying dividend payout ratio following the adoption of both standards.
4 December 31, 2023 Sun Life Financial Inc. MANAGEMENT'S DISCUSSION & ANALYSIS Our four pillars define the businesses and markets in which we operate.

6 December 31, 2023 Sun Life Financial Inc. MANAGEMENT'S DISCUSSION & ANALYSIS Following the adoption of IFRS 17 and IFRS 9, progress against our medium-term financial objectives are measured on a two-year basis.


2. Financial Objectives
Our medium-term financial objectives are outlined as follows:

IFRS 17 and IFRS 9
Measure(1)
Medium-term
financial objectives(2)(3)
2-Year(2)(4)
Underlying EPS growth
Growth in EPS reflects the Company's focus on generating sustainable earnings for shareholders.
8%-10% 11%
Underlying ROE
ROE is a significant driver of shareholder value and is a major focus for management across all businesses.
18%+ 17.4%
Underlying dividend payout ratio
Payout of capital versus shareholder value, based on underlying net income.
40%-50% 48%

(1)Underlying EPS, underlying ROE and underlying dividend payout ratio are non-IFRS financial measures. See section M - Non-IFRS Financial Measures in this document. Underlying dividend payout ratio represents the ratio of common shareholders' dividends to diluted underlying EPS. See
section J - Capital and Liquidity Management - 3 - Shareholder Dividends in this document for further information regarding dividends.
(2)Our medium-term financial objective for underlying ROE changed to 18%+ following the adoption of IFRS 17 and IFRS 9, an increase from 16%+ prior to transition. Our medium-term financial objectives remain consistent for underlying earnings per share and underlying dividend payout ratio following the adoption of both standards. 2022 restated results may not be fully representative of our future earnings profile, as we were not managing our asset and liability portfolios under the new standards. See the heading "Note to Readers: 2022 Restated Results on Adoption of IFRS 17 and IFRS 9" in section A - How We Report Our Results in this document.
(3)Although considered reasonable, we may not be able to achieve our medium-term financial objectives as our assumptions may prove to be inaccurate. Accordingly, our actual results could differ materially from our medium-term financial objectives as described above. Our medium-term financial objectives do not constitute guidance. Our medium-term financial objectives are forward-looking non-IFRS financial measures and additional information is provided in this MD&A in section P - Forward-looking Statements - Medium-Term Financial Objectives.
(4)Underlying EPS growth, ROE and dividend payout ratio are calculated using an average. Underlying EPS growth reflects one-year growth (2023 over 2022). The beginning period is January 1, 2022 and ending period is December 31, 2023.

In the year and over the medium-term, we have performed well against our medium-term financial objectives in a challenging operating environment reflecting economic and geopolitical uncertainties.

3. Sustainability Plan

Our sustainability ambition is to maximize our positive impact and ensure the resiliency of our organization, in support of our Purpose of helping Clients achieve lifetime financial security and live healthier lives. We aim to create competitive advantage and differentiation for our business through the following focus areas of our sustainability plan:

Increasing Financial Security: We aspire to increase the lifetime financial security of our Clients, employees and communities. We’re increasing access to and use of insurance and wealth products, and empowering and educating people to improve financial security outcomes.

We manage assets with material environmental, social and governance ("ESG") factors embedded in our investment processes and offer our Clients sustainable investing opportunities. In addition, we invest our own assets in ways that support a low-carbon and more inclusive economy.

Climate change: We are committed to being part of the climate solution. We’re decarbonizing our business and engaging with our stakeholders to support the transition to a low-carbon economy. Meaningful climate action is essential to delivering on our Purpose and ensuring the resiliency of our business.

Our sustainability plan builds from our foundation as a Trusted and Responsible Business. We aspire to be a responsibly-managed business that is Client-focused, competitive, forward-thinking and sustainable for the long term.

4. Acquisitions and Other

The following developments occurred since January 1, 2023. Additional information concerning acquisitions and dispositions is provided in Note 3 in our 2023 Annual Consolidated Financial Statements.

On February 1, 2023, we completed the acquisition of a 51%(1) interest in Advisors Asset Management, Inc. ("AAM"), a leading independent U.S. retail distribution firm. AAM's strong U.S. retail distribution capabilities provides an attractive opportunity for SLC Management to meet the growing demand for alternative assets among U.S. HNW investors. AAM provides a range of solutions and products to financial advisors at wirehouses, registered investment advisors and independent broker-dealers, overseeing US$41.4 billion (approximately C$54.9 billion) in assets as at December 31, 2023, with 10 offices across nine U.S. states. Sun Life has the option to acquire the remaining interest in AAM starting in 2028. As a result of the transaction, total shareholders’ equity was reduced by $156 million, primarily driven by the establishment of financial liabilities associated with the anticipated increase of our future ownership in AAM.

On February 1, 2023, we completed the sale of the sponsored markets business(2) from Sun Life Assurance to Canadian Premier Life Insurance
Company (re-branded to Securian Canada).

On April 3, 2023 we completed the sale of SLF of Canada UK Limited ("Sun Life UK") to Phoenix Group Holdings plc ("Phoenix Group") for approximately $418 million. Sun Life UK managed life and pension policies as well as payout annuities for UK Clients, was closed to new sales and operated as a run-off business since 2001. Under the agreement, we will retain our economic interest in the payout annuities business through a reinsurance treaty, which, effective Q2'23, is recorded in In-force Management within the U.S. business group. Phoenix Group is the UK's largest long-term savings and retirement business, with £269 billion(3) of assets under administration and approximately 12 million customers(3). As part of the sale, we will establish a long-term partnership to become a strategic asset management partner to Phoenix Group. Our asset management companies, MFS and SLC Management, will continue to manage approximately $8 billion of Sun Life UK's general account. In addition, Phoenix Group has set a goal to invest approximately US$25 billion in North American public and private fixed income and alternative investments over the next five years. MFS and SLC Management will be material partners to Phoenix Group in achieving this goal. In Q3'22, we recognized an impairment charge pertaining to the attributed goodwill that was not expected to be recovered through the sale. In Q2'23, we recognized a gain of $19 million in reported net income.

Effective July 1, 2023 we commenced our 15-year exclusive bancassurance partnership with Dah Sing Bank ("Dah Sing"). Under this
partnership, Sun Life will be the exclusive provider of life insurance solutions to Dah Sing's approximately 570,000 retail banking customers, helping to fulfill their savings and protection needs at different life stages. This is Sun Life's first exclusive bancassurance partnership in Hong Kong and will be a valuable complement to our existing network of over 2,500 expert insurance advisors.

On October 3, 2023, we acquired Dialogue Health Technologies Inc. ("Dialogue"). As a result of this acquisition, our ownership interest increased from 23% to 95% for cash proceeds of $272 million (for equity not previously owned by Sun Life or rolled by certain members of Dialogue's executive management). Dialogue is a Canadian based health and wellness virtual care platform.

2023 vs. 2022

Underlying net income of $3,728 million increased $359 million or 11%, driven by:
•Wealth & asset management up $53 million: Higher investment income driven by volume growth and an increase in yields, partially offset by lower fee-related earnings in MFS, Canada, and Asia.
•Group - Health & Protection up $350 million: Business premium growth across all U.S. businesses and Canada, improved disability experience in Canada, higher investment contributions in the U.S., and DentaQuest contributions.
•Individual - Protection up $137 million: Business growth reflecting good sales momentum in Asia, improved protection experience, and higher investment contributions in Canada, partially offset by lower earnings due to the sale of Sun Life UK(1).
•Corporate expenses & other $(181) million increase in net loss includes higher debt financing costs.
•In addition, the earnings by business type above include higher earnings on surplus, driven by an increase in realized gains and net interest income from higher rates, and higher operating expenses reflecting volume growth and continued investments in the business.














(1)On April 3, 2023 we completed the sale of SLF of Canada UK Limited to Phoenix Group Holdings plc ("the sale of Sun Life UK"). For additional information, refer to Note 3 of our 2023 Annual Consolidated Financial Statements.
10 December 31, 2023 Sun Life Financial Inc. MANAGEMENT'S DISCUSSION & ANALYSIS Reported net income of $3,086 million increased $215 million or 7%, driven by the increase in underlying net income and:


•ACMA impacts;
•Gain on the sale of the sponsored markets business in Canada(1); and
•The impact of the Bermuda Corporate Income Tax Change(2); partially offset by
•Market-related impacts reflecting real estate experience(3) and interest rates, partially offset by equity markets;
•Fair value changes in management's ownership of MFS shares; and
•The impact of the Canada Tax Rate Change(4) and a gain on the sale-leaseback of the Wellesley office in the U.S. in the prior year were mostly offset by a $170 million charge related to the sale of Sun Life UK(5) and a higher increase in SLC Management's acquisition-related liabilities(6) in the prior year.

Foreign exchange translation led to an increase of $77 million and $73 million to underlying net income and reported net income, respectively.

Underlying ROE was 17.8% and reported ROE was 14.7% (2022 - 17.0% and 14.5%, respectively).

1.Market-related impacts
Market-related impacts represent the difference between actual versus expected market movements(7). Market-related impacts resulted in a decrease of $454 million to reported net income, primarily reflecting unfavourable real estate experience.

2.Assumption changes and management actions
The net impact of assumption changes and management actions was an increase of $36 million to reported net income and includes methods and assumptions changes on insurance contracts as well as related impacts. These included favourable impacts from modelling enhancements in Asia and financial-related assumptions, which were partially offset by unfavourable policyholder behaviour updates in Asia, mortality updates in the U.S., and refinements to Sun Life Health in Canada. For additional details refer to "Assumption Changes and Management Actions by Type" in section F - Contractual Service Margin in this document.

3.Other adjustments
Other adjustments decreased reported net income $224 million, reflecting DentaQuest integration costs and amortization of acquired intangible assets, and SLC Management acquisition-related costs(8), partially offset by gains on the sale of the sponsored markets business in Canada(1) and the sale of Sun Life UK(5), and the impact of the Bermuda Corporate Income Tax Change(2).

4. Experience-related items
Notable experience items in the current year included:
•Favourable morbidity experience largely in Canada and in U.S. medical stop-loss;
•Unfavourable expense experience largely in Canada, U.S. Dental, and Asia;
•Unfavourable credit experience that impacted Canada results; and
•Other experience was favourable reflecting various smaller items.

5.Income taxes
The statutory tax rate is impacted by various items, such as lower taxes on income subject to tax in foreign jurisdictions, tax-exempt investment income, and other sustainable tax benefits.

On December 27, 2023, Bermuda enacted its Corporate Income Tax Act 2023, which will apply a 15% income tax beginning on
January 1, 2025. Bermuda Corporate Income Taxes are expected to be a covered tax and will reduce Pillar Two top-up taxes which would otherwise be payable to other jurisdictions. The enacted legislation provides an economic transition adjustment that aligns an entity’s starting point for the tax regime more closely with its economic position prior to the application of the Corporate Income Tax 2023. The benefit of this economic transition adjustment has been recognized in 2023. As a result, total Company reported net income increased by $51 million, reflected in Other adjustments. The Bermuda Corporate Income Tax is not expected to have a material impact on Sun Life’s consolidated financial statements when it becomes effective in 2025. Refer to Note 19 in the 2023 Annual Consolidated Financial Statements for more information.

The effective income tax rate(9) on underlying net income and reported net income was 17.3% and 11.7%, respectively.

(1)On February 1, 2023, we completed the sale of the sponsored markets business from Sun Life Assurance, a wholly owned subsidiary of SLF Inc., to Canadian Premier Life Insurance Company (re-branded to Securian Canada) ("sale of the sponsored markets business").
(2)Refer to the heading "Income taxes" in this section for more information.
(3)Real estate experience reflects the difference between the actual value of real estate investments compared to management's longer-term expected returns supporting insurance contract liabilities ("real estate experience").
(4)On December 15, 2022, legislation implementing an additional surtax of 1.5% applicable to banks and life insurer's taxable income in excess of $100 million was enacted in Canada ("Canada Tax Rate Change"). This legislation applied retroactively to the Federal Budget date of April 7, 2022. As a result, total Company reported net income increased by $141 million in Q4'22, reflected in Other adjustments.
(5)On April 3, 2023 we completed the sale of SLF of Canada UK Limited to Phoenix Group Holdings plc ("the sale of Sun Life UK"). In Q3'22, we recognized an impairment charge of $170 million pertaining to the attributed goodwill that was not expected to be recovered through the sale.
(6)Reflects the changes in estimated future payments for acquisition-related contingent considerations and options to purchase remaining ownership interests of SLC Management affiliates.
(7)Except for risk free rates which are based on current rates, expected market movements are based on our medium-term outlook which is reviewed annually.
(8)Includes an increase in SLC Management's acquisition-related liabilities in Q3'23, which reflects the changes in estimated future payments for acquisition-related contingent considerations and options to purchase remaining ownership interests of SLC Management affiliates.
(9)Our effective income tax rate on reported net income is calculated using Total income (loss) before income taxes, as detailed in Note 19 in our 2023 Annual Consolidated Financial Statements. Our effective income tax rate on underlying net income is calculated using pre-tax underlying net income, as detailed in section M - Non-IFRS Financial Measures in this document, and the associated income tax expense.

6. Impacts of foreign exchange translation
We operate in many markets worldwide, including Canada, the United States, the United Kingdom, Ireland, Hong Kong, the Philippines, Japan, Indonesia, India, China, Australia, Singapore, Vietnam, Malaysia and Bermuda, and generate revenues and incur expenses in local currencies in these jurisdictions, which are translated to Canadian dollars.

Items impacting a reporting period, such as Revenue, Expenses, and Reported net income (loss) in our Consolidated Statements of Operations, as well as underlying net income (loss), and sales, are translated into Canadian dollars using average exchange rates for the appropriate daily, monthly, or quarterly period. For Assets and Liabilities in our Consolidated Statements of Financial Position, as well as the AUM and certain components of the Drivers of Earnings disclosure, period-end rates are used for currency translation purposes.

The following table provides the foreign exchange rates for the U.S. dollar, which generates the most significant impact of foreign exchange translation, over the past four quarters and two years.

Exchange rate Quarterly results Full year
Q4'23 Q3'23 Q2'23 Q1'23 2023 2022
U.S. Dollar - Average
1.361 1.341 1.343 1.352 1.350 1.301
U.S. Dollar - Period end
1.325 1.358 1.324 1.352 1.325 1.355

The relative impacts of foreign exchange translation in any given period are driven by the movement of foreign exchange rates as well as the proportion of earnings generated in our foreign operations. In general, net income benefits from a weakening Canadian dollar and is adversely affected by a strengthening Canadian dollar as net income from the Company's international operations is translated back to Canadian dollars. Conversely, in a period of losses, the weakening of the Canadian dollar has the effect of increasing losses in foreign jurisdictions. We generally express the impacts of foreign exchange translation on net income on a year-over-year basis.

Foreign exchange translation led to an increase of $77 million and $73 million in underlying net income and reported net income, respectively.

Total group health & protection sales increased $388 million or 15% from prior year ($332 million(1) or 13%(1), excluding foreign exchange translation).
•Canada group sales increased $58 million or 11%, driven by higher large case sales.
•U.S. group sales increased $270 million(1) or 15%(1), driven by higher Dental(2) sales in Medicare Advantage, Medicaid, and commercial dental, as well as higher medical stop-loss sales, partially offset by lower employee benefits sales.

Total individual protection sales increased $724 million or 41% from prior year ($694 million(1) or 39%(1), excluding foreign exchange translation).
•Canada individual sales increased $113 million or 23%, driven by higher participating whole life insurance sales.
•Asia individual sales increased $581 million(1) or 46%(1), driven by higher sales in Hong Kong, International, and India, partially offset by lower sales in Vietnam.

New business CSM represents growth derived from sales activity in the period. The impact of new insurance business drove a $1,253 million increase in CSM, compared to $762 million in the prior year, driven by higher individual protection sales in Asia in Hong Kong and High-Net-Worth ("HNW"), and Canada.

Assumption Changes and Management Actions by Type
The impact on CSM of ACMA is attributable to insurance contracts and related impacts under the general measurement approach ("GMA") and variable fee approach ("VFA"). For insurance contracts measured under the GMA, the impacts flow through the CSM at locked-in discount rates. For insurance contracts measured under the VFA, the impact flows through the CSM at current discount rates.

The following table sets out the impacts of ACMA on our reported net income and CSM in 2023.

At and For the Year Ended December 31, 2023
($ millions)
Reported net income impacts (Post-tax)(1)(2)(3)
Deferred in CSM (Pre-tax)(2)(3)(4)
Comments
Mortality/morbidity (98) 179
Updates to reflect mortality/morbidity experience in all jurisdictions. The largest items were favourable mortality impacts in the UK Annuities in the U.S and GRS in Canada.
These were offset partially by adverse mortality in In-force Management in the U.S. Mortality updates impacting CSM favourably are funded at locked-in rates that are lower than current rates resulting in a negative net income impact. Additionally, favourable morbidity impacts in Group Benefits in the U.S. were largely offset by unfavourable morbidity updates in Sun Life Health in Canada.

Policyholder behaviour (91) (274)
Updates to reflect lapse and policyholder behaviour in all jurisdictions. The largest items were an adverse lapse impact in Individual Term and Universal Life in Canada, and in International, Hong Kong and Vietnam in Asia.
Expense 7 (171) Updates to reflect higher costs related to IFRS 17 infrastructure and higher costs in Canada.
Financial 116 202
Updates to various financial related assumptions including the ultimate risk-free rate.
Modelling enhancement and other 102 428
Various enhancements and methodology changes. The largest items were favourable impacts from refinements to the modelling of guarantees for the Individual Par in Canada and International Universal Life in Asia, as well as modelling enhancements in Vietnam in Asia offset partially by a refinement in Sun Life Health in Canada and to reinsurance and other provisions in Hong Kong in Asia.

(3)The impact of ACMA of $90 million and $318 million of pre-tax net income and CSM, respectively, disclosed in Note 10.B of the 2023 Annual Consolidated Financial Statements, differs from the $36 million and $364 million, respectively, of ACMA shown above. This is a variance of $54 million and $(46) million, respectively. The difference is $16 million of tax on net income, and $38 million and $(46) million, respectively, of net income and CSM for non-liability impacts related to ACMA included in the above but excluded from Note 10.B in the 2023 Annual Consolidated Financial Statements.

1. Life Insurance Capital Adequacy Test
The Office of the Superintendent of Financial Institutions has developed the regulatory capital framework referred to as the Life Insurance Capital Adequacy Test for Canada. LICAT measures the capital adequacy of an insurer using a risk-based approach and includes elements that contribute to financial strength through periods when an insurer is under stress as well as elements that contribute to policyholder and creditor protection wind-up.

SLF Inc. is a non-operating insurance company and is subject to the LICAT guideline. Sun Life Assurance, SLF Inc.'s principal operating life insurance subsidiary, is also subject to the LICAT guideline.

SLF Inc.'s LICAT ratio of 142% and Sun Life Assurance's LICAT ratio of 139% as at January 1, 2023 increased 12 percentage points compared to December 31, 2022, from the transition to IFRS 17. The largest driver of change was the reduction in the LICAT base solvency buffer ("BSB") scalar from 1.05 to 1.0 which contributed seven percentage points.

SLF Inc.'s LICAT ratio of 149% as at December 31, 2023 increased seven percentage points compared to January 1, 2023, driven by reported net income, capital optimization and market movements, partially offset by shareholder dividend payments, subordinated debt redemption, M&A activity, and share buybacks.

Sun Life Assurance's LICAT ratio of 141% as at December 31, 2023 increased two percentage points compared to January 1, 2023, driven by reported net income, capital optimization, and market movements, largely offset by dividend payments to SLF Inc. and M&A activity.

The Sun Life Assurance LICAT ratios in both periods are well above OSFI's supervisory ratio of 100% and regulatory minimum ratio of 90%.



                 MANAGEMENT'S DISCUSSION & ANALYSIS Sun Life Financial Inc. December 31, 2023 17


2. Capital
On transition to the new standards, total capital of $40.6 billion as at January 1, 2023 increased $4.4 billion compared to December 31, 2022 driven by the establishment of the CSM, which includes transfers from Common shareholders' equity and equity in the participating account to the CSM.

Our total capital consists of subordinated debt and other capital instruments, CSM, equity in the participating account and total shareholders' equity which includes common shareholders' equity, preferred shares and other equity instruments, and non-controlling interests. As at December 31, 2023, our total capital was $42.4 billion, an increase of $1.7 billion compared to January 1, 2023. The increase to total capital included reported net income of $3,086 million, an increase of $921 million in CSM, the issuance of $500 million principal amount of Series 2023-1 Subordinated Unsecured 5.50% Fixed/Floating Debentures, which is detailed below, and net unrealized gains on FVOCI assets of
$485 million. This was partially offset by the payment of $1,762 million of dividends on common shares of SLF Inc. ("common shares"), the redemption of $1 billion principal amount of Series 2016-2 Subordinated Unsecured 3.05% Fixed/Floating Debentures, which is detailed below, the unfavourable impacts of foreign exchange translation of $344 million included in other comprehensive income (loss) ("OCI"), a decrease of $186 million from the repurchase and cancellation of common shares, and the impact related to the acquisition of AAM of
$156 million(1).

Our capital and liquidity positions remain strong with a LICAT ratio of 149% at SLF Inc., a financial leverage ratio of 21.5%(2) and $1.6 billion in cash and other liquid assets(2) as at December 31, 2023 in SLF Inc.(3) (December 31, 2022 - $1.1 billion).

Capital Transactions
On July 4, 2023, SLF Inc. issued $500 million principal amount of Series 2023-1 Subordinated Unsecured 5.50% Fixed/Floating Debentures due 2035. Sun Life intends to use an amount equal to the net proceeds from the offering to finance or refinance, in whole or in part, eligible assets as defined in our Sustainability Bond Framework.

On September 19, 2023, SLF Inc. redeemed all of the outstanding $1 billion principal amount of Series 2016-2 Subordinated Unsecured 3.05% Fixed/Floating Debentures, in accordance with the redemption terms attached to such debentures. The redemptions were funded from existing cash and liquid assets in SLF Inc.

Normal Course Issuer Bids
On August 24, 2023, SLF inc. announced that OSFI and the Toronto Stock Exchange ("TSX") had approved its previously announced normal course issuer bid to purchase up to 17 million of its common shares (the "NCIB”). The NCIB commenced on August 29, 2023 and continues until
August 28, 2024, such earlier date as SLF Inc. may determine, or such date as SLF Inc. completes its purchases of common shares pursuant to the NCIB. Purchases under the NCIB may be made through the facilities of the TSX, other Canadian stock exchanges and/or alternative Canadian trading platforms, at prevailing market rates. Subject to regulatory approval, purchases under the NCIB may also be made by way of private agreements or share repurchase programs under issuer bid exemption orders issued by securities regulatory authorities. Any purchases made under an exemption order issued by a securities regulatory authority will generally be at a discount to the prevailing market price. The actual number of common shares purchased under the NCIB, and the timing of such purchases (if any), will be determined by SLF Inc. Any common shares purchased by SLF Inc. pursuant to the NCIB will be cancelled or used in connection with certain equity settled incentive arrangements. The NCIB will provide the Company with the flexibility to acquire common shares in order to return capital to shareholders as part of its overall capital management strategy.

In 2023, SLF Inc. purchased approximately 2.8 million common shares at a total cost of $186 million pursuant to the NCIB. All of the common shares purchased under SLF Inc.'s NCIB were subsequently cancelled.

Financial Strength Ratings
Independent rating agencies assign credit ratings to securities issued by companies and assign financial strength ratings to financial institutions such as Sun Life Assurance.

The financial strength ratings assigned by rating agencies are intended to provide an independent view of the creditworthiness and financial strength of a financial institution. Each rating agency has developed its own methodology for the assessment and subsequent rating of life insurance companies.

Rating agencies do not assign a financial strength rating for SLF Inc., however, credit ratings are assigned to the securities issued by SLF Inc. and its subsidiaries and are described in SLF Inc.'s AIF under the heading Security Ratings.

1. Asset Management
Our Asset Management business group is comprised of MFS and SLC Management. MFS is a premier global asset manager offering a comprehensive selection of financial products and services that deliver superior value, actively managing assets for retail and institutional investors around the world. SLC Management is a global asset manager with capabilities across fixed income and alternative asset classes including public and private fixed income, real estate equity and debt, and infrastructure equity, and manages assets on behalf of institutional investors and HNW Clients around the world.
2023 Highlights

•We ended 2023 with $1,015.9 billion in assets under management consisting of $792.8 billion (US$598.6 billion) in MFS and $223.1 billion in SLC Management.
•Total Asset Management net outflows of $26.4 billion reflected net outflows of $38.9 billion (US$28.8 billion) from MFS partially offset by SLC Management net inflows of $12.5 billion.



MFS
•MFS generated solid net income and sustained a strong pre-tax net operating profit margin(1), despite challenging market conditions.
•Delivered strong long-term investment performance with 97%, 95% and 30% of MFS' U.S. retail mutual fund assets ranked in the top half of their Morningstar categories based on ten-, five- and three-year performance, respectively, as at December 31, 2023.
•During the year, MFS became the 9th largest fund group(2) for the U.S. retail mutual fund industry based on AUM.
•MFS is preparing to go to market with active exchange traded funds ("ETFs") over the next year, continuing to expand the diverse range of investment products offered to Clients.


SLC Management
•On February 1, we completed the acquisition of a 51%(3) interest in Advisors Asset Management, Inc. (“AAM”), a leading independent U.S. retail distribution firm, with the option to acquire the remaining interest starting in 2028. We also entered into a strategic partnership with Scotiabank in Q3'23 to distribute alternative investment capabilities to the Canadian retail market. AAM's strong U.S. retail distribution capabilities, coupled with the strategic partnership with Scotiabank, provides an attractive opportunity for SLC Management to meet the growing demand for alternative assets among HNW investors.
•AAM announced it will distribute BGO IREIT(4), a non-traded real estate investment trust launched by BentallGreenOak (“BGO”), and Crescent Private BDC, a non-traded closed-end fund launched by Crescent Capital Group LP ("Crescent"), in early 2023, highlighting the strategic benefit of adding this distribution channel.
•BGO achieved a successful final close of its third UK Secured Lending Fund, with a total of £1.4 billion in commitments from over 25 global institutional investors. The fund surpassed its initial target and has become one of the largest European fundraises for a debt strategy entirely focused on the UK.
•Crescent achieved a successful final close of its eighth private credit solutions fund(5), raising US$8 billion in investable capital. The fund exceeded its initial target and has become the largest capital raise in Crescent’s history.
•SLC Management continued to demonstrate its commitment to sustainable investing with BGO winning a number of awards including the 2023 ENERGY STAR® Partner of The Year – Sustained Excellence Award by the U.S. Environmental Protection Agency and the U.S. Department of Energy for the 13th consecutive year, and with InfraRed Capital Partners (“InfraRed”) continuing to invest capital in companies helping to build a sustainable future.

20 December 31, 2023 Sun Life Financial Inc. MANAGEMENT'S DISCUSSION & ANALYSIS Our strategy is to provide investment products through MFS and SLC Management that will deliver long-term value to our Clients in active asset management as well as fixed income and alternative asset classes.


Strategy and Outlook
MFS competes primarily in the global institutional, U.S. retail and select non-U.S. retail markets. SLC Management competes primarily in the global institutional market, offering a broad and deep fixed income and real assets platform through affiliate managers. SLC Management leverages Sun Life’s long-standing expertise in private asset class investments, augmented by the specialized alternative capabilities of SLC Management's affiliate managers, to offer customized investment solutions to investors. In addition, with the acquisition of a majority interest in AAM and the partnership with Scotia Global Wealth Management, SLC Management will also deliver solutions to the retail HNW market in North America.

MFS: Continue to deliver superior investment performance while allocating capital responsibly for our Clients
MFS' active management strategy focuses on delivering value to our Clients over the long-term. Our relative performance provides us with a strong competitive position:
•MFS is well-positioned to attract flows from all Client sectors that are seeking risk-managed capital appreciation over the long-term based on our disciplined, long-term approach. We are engaging Clients to align with MFS to focus on longer investment horizons, to leverage our proven ability to deliver over benchmark performance through a market cycle.
•Our strong leadership on ESG is embedded in our overall investment approach of allocating capital responsibly on behalf of our Clients.
•Our continued strategic focus to build out institutional fixed income product and sales capabilities and broaden our non-U.S. retail initiatives enables us to meet Clients' unique and local needs.
•MFS strives to maintain margins in the top quartile of active managers while maintaining our commitment to provide long-term value to Clients.
•We continue to focus on diversity at all levels and promoting an inclusive culture.
SLC Management: Help investors meet their investment objectives by offering a broad suite of alternative asset classes and fixed income strategies
We are well-positioned to take advantage of key trends in our target markets:
•Institutional investors continue to increase allocations to alternative investments and fixed income.
•Growing demand for alternative investments, including demand among North American HNW retail investors.
•Consolidation of investment manager relationships by institutional investors.
•Realizing the synergies from alternative asset management and insurance capabilities.
•An increasing focus by some investors on ESG and sustainable investing.

Our strategy is to continue to deliver superior investment performance, expand and deepen our distribution relationships, and build out our product lineup, while retaining our top talent. SLC Management is positioned for growth over the medium-term; our objectives(1) are to achieve AUM of $225 billion, operating margin of 30%-35%, and underlying net income of $235 million by 2025. We offer our Clients a compelling suite of investment capabilities to meet their needs, including:
•Leading public and private fixed income capabilities, spanning both investment grade and alternative credit
•Global real estate expertise across both equity and debt investments, and
•Global infrastructure capabilities.
Outlook
MFS
The potential for a global recession remains. We are in an environment of slowing growth with capital and labour costs remaining high, which creates the need for more companies to recapitalize at higher rates in the face of softer revenue growth. This will continue to create a more challenging environment to generate value in the short to medium-term. Companies who can operate successfully in this more challenging, higher cost environment will be rewarded by investors. This could create greater opportunities for active managers to outperform benchmarks that have not been present. MFS employs an investment philosophy that involves a long-term approach and looks across the complete business cycle. Our scale, proven long-term track record and broad product portfolios, coupled with our investment philosophy, position us well to deliver strong results over a market cycle. Our expense structure leverages significant variable costs based on assets, sales or profitability, and as a result a majority of our expense base adjusts with market dynamics. In addition, we will continue to be diligent with discretionary spending while investing in strategic initiatives that help grow the business over the long-term.

SLC Management
With current economic and geopolitical uncertainty, we expect to see more volatility in equity markets driven by higher-for-longer interest rates and continued uncertainty on stabilization of rates. These macroeconomic headwinds are expected to moderate our ability to raise capital as investors rebalance their portfolios, or defer committing further capital, as well as to deploy capital given the challenging environment for transactions. However, we expect to see continued demand for yield-orientated fixed income and alternative assets classes, as these asset types continue to provide an opportunity for portfolio diversification, a potential hedge against inflation, and a reduction in overall risk exposure across investments. We believe that we are well positioned to meet this demand with our platform of world-class investment capabilities, complimentary businesses that drive product and distribution opportunities, and our ability to leverage global resources. The acquisition of a majority stake in AAM and partnership with Scotia Global Wealth Management provides further momentum to SLC Management to grow and expand our retail HNW business in North America. The investment capabilities we use for our Clients are the same capabilities that we use in managing the general account of Sun Life; this facilitates co-investment opportunities that result in an alignment of interest with our Clients and enables SLC Management's speed to market for products.



(1)Although considered reasonable by SLC Management, we may not be able to achieve our medium-term financial objectives as our assumptions may prove to be inaccurate.

                 MANAGEMENT'S DISCUSSION & ANALYSIS Sun Life Financial Inc. December 31, 2023 23





Profitability
2023 vs. 2022
Asset Management underlying net income of $1,239 million increased $1 million driven by:
•MFS down $36 million (US$59 million): Lower fee income from average net assets ("ANA") and higher expenses, partially offset by an increase in net investment income and favourable foreign exchange translation.
•SLC Management up $37 million: The increase in underlying net income was driven by higher fee-related earnings, and higher retention expenses in the prior year that did not repeat. Fee-related earnings(1) increased 22% driven by higher AUM, reflecting strong capital raising and deployment across the platform and the AAM acquisition(2). Fee-related earnings margin(1) and pre-tax net operating profit margin(1) for 2023 were 24% and 22%, respectively (2022 - 24% and 23%, respectively).

Reported net income of $1,067 million decreased $81 million or 7%, reflecting fair value changes in management's ownership of MFS shares and a decline in value of real estate investments held in the SLC Management surplus account, partially offset by a lower increase in SLC Management's acquisition-related liabilities(3) compared to the prior year.

Foreign exchange translation led to an increase of $37 million and $35 million in underlying net income and reported net income, respectively.

Growth
2023 vs. 2022
Asset Management AUM of $1,015.9 billion increased $63.9 billion or 7% driven by:
•Net asset value changes of $91.6 billion; and
•AUM driven by the AAM acquisition of $5.2 billion; partially offset by
•Net outflows of $26.4 billion; and
•Client distributions of $6.5 billion.

MFS' AUM increased US$50.7 billion or 9%, driven by:
•Increase in asset values from higher equity markets of US$79.5 billion, partially offset by net outflows of US$28.8 billion.

In Q4'23, 97%, 95%, and 30% of MFS' U.S. retail mutual fund assets ranked in the top half of their Morningstar categories based on ten-, five- and three-year performance, respectively.

SLC Management's AUM increased $13.5 billion or 6% driven by:
•Net inflows of $12.5 billion, the AAM acquisition of $5.2 billion, and asset value changes of $2.3 billion, partially offset by Client distributions of $6.5 billion.
•Net inflows were comprised of capital raising and Client contributions, totaling $24.6 billion, partially offset by outflows of
$12.2 billion.

SLC Management's FE AUM increased $12.4 billion or 8% driven by:
•Net inflows of $14.2 billion, the AAM acquisition of $5.2 billion, and asset value changes of $0.2 billion, partially offset by Client distributions of $7.2 billion.
•Net inflows were comprised of capital deployment and Client contributions, totaling $24.6 billion, partially offset by outflows of
$10.4 billion.

Acquisition of Advisors Asset Management, Inc.
On February 1, 2023, we completed the acquisition of a 51%(4) interest in Advisors Asset Management, Inc. ("AAM"), a leading independent U.S. retail distribution firm. AAM's strong U.S. retail distribution capabilities provides an attractive opportunity for SLC Management to meet the growing demand for alternative assets among U.S. HNW investors. AAM provides a range of solutions and products to financial advisors at wirehouses, registered investment advisors and independent broker-dealers, overseeing US$41.4 billion (approximately C$54.9 billion) in assets as at December 31, 2023, with 10 offices across nine U.S. states. Sun Life has the option to acquire the remaining interest in AAM starting in 2028. As a result of the transaction, total shareholders' equity was reduced by $156 million, primarily driven by the establishment of financial liabilities associated with the anticipated increase of our future ownership in AAM. For additional information, refer to Note 3 in our 2023 Annual Consolidated Financial Statements.

(3)Effective January 1, 2023, Canada wealth sales & asset management gross flows have been updated to exclude retained sales. Prior period amounts have been updated to reflect this change.

Profitability
2023 vs. 2022
Underlying net income of $1,376 million increased $313 million or 29%, reflecting:
•Wealth & asset management up $68 million: Increase in investment income driven by higher volume and yields, partially offset by lower fee-related earnings.
•Group - Health & Protection up $175 million: Business premium growth and improved disability experience reflecting higher margins, lower claims volumes, and shorter claims durations.
•Individual - Protection up $70 million: Growth of In-force business, higher investment contributions and improved protection experience.
•In addition the earnings across all businesses above include higher earnings on surplus driven by an increase in realized gains and net interest income from higher rates, and higher operating expenses reflecting volume growth and continued investments in the business.

Reported net income of $1,252 million was in line with prior year, as the increase in underlying net income, ACMA impacts, and a gain on the sale of the sponsored markets business was mostly offset by market-related impacts and the prior year impact from the Canada Tax Rate Change(1). Market-related impacts were primarily from interest rates and real estate experience, partially offset by higher equity markets.

Growth
2023 vs. 2022
Canada's sales included:
•Wealth sales & asset management gross flows of $15.0 billion were up 3%, driven by higher Individual Wealth sales, primarily from mutual funds, largely offset by lower defined contribution sales in GRS.
•Group - Health & Protection sales of $591 million were up 11% driven by higher large case sales.
•Individual - Protection sales of $609 million were up 23%, driven by higher participating whole life insurance sales.

AUM for wealth businesses, including GRS, was $166.7 billion as at December 31, 2023, an increase of $14.4 billion or 9.5%, reflecting market movements and net inflows.

Sale of Sponsored Markets Business
On February 1, 2023, we completed the sale of the sponsored markets business(2) from Sun Life Assurance to Canadian Premier Life Insurance
Company (re-branded to Securian Canada). For additional information, refer to Note 3 of our 2023 Annual Consolidated Financial Statements.

In addition, our U.S. business manages an in-force block of approximately 225,000 individual life insurance and annuity policies as well as a block of run-off reinsurance.
2023 Highlights

Growing our business
•Sun Life U.S. delivered strong double-digit growth in underlying earnings, sales, and revenue again in 2023, driven by the successful execution of our strategy to help Clients access the health care and coverage they need as well as contributions from the DentaQuest acquisition.
•Recorded more than US$650 million in total new dental sales since closing the DentaQuest acquisition on June 1, 2022, including the largest Medicare Advantage sale in DentaQuest history in 2023. Commercial dental sales also increased 55% in 2023 as we leverage our combined strengths from the DentaQuest acquisition.
•Employee Benefits revenue increased 14% compared to 2022, reflecting strong sales and persistency results, supported by investments in products and technology, higher average premiums per case and disciplined pricing.
•Increased supplemental health premiums by 34% year-over-year and recognized in 2023 as the Voluntary Sales Growth Leader in the large carrier category by Eastbridge Consulting(1). Voluntary benefits include supplemental health benefits that help members pay for costs that may not be covered by their medical plans.


Helping Clients access the health care and coverage they need
•PinnacleCare's personalized care navigation solutions helped members get timely access to high quality healthcare and provided them with the knowledge to make confident decisions about their health. In 2023, more than 50% of the appointments secured for members facing a new or progressing cancer diagnosis were expedited by Health Navigator to a date sooner than the patient was able to schedule through typical hospital access channels.
•Expanded our Advantage Dental+ practices with five new offices in Texas. These practices are focused on providing high quality, preventive-focused oral health care to children with Medicaid coverage.

•Launched two new commercial dental plan options that help members reduce out-of-pocket costs, encourage preventive care, and maximize their dental coverage.

•Announced a partnership with in-home, tech-enabled medical care provider Somatus to provide one-on-one support to our members with chronic kidney disease and congestive heart failure, two common high-cost conditions.
•Established a partnership with Virtual MeTM(3) to provide our Health Navigator product through their telehealth services that cater to business clients, as well as individuals who are underinsured or uninsured.


Making care and benefits easier through digital solutions
•Expanded our partnership with AbleTo, a leading provider of high-quality, evidence-based virtual mental health therapy and coaching solutions, to add a digital, on-demand wellness program for our group life insurance members, supporting emotional and mental health.
•Partnered with Goodpath, an integrative, virtual clinic, to provide access to whole-person care services for our disability members to improve treatment for back and musculoskeletal conditions and long COVID-19.
•Extended our partnership with Teledentistry.com to include DentaQuest members, offering members in selected states 24/7 virtual access to dental providers, making it easier to get dental care and advice digitally.
•Improved the stop-loss underwriting process by introducing an advanced digital underwriting tool in the U.S. Leveraging this tool, which uses machine learning, we were able to provide medical stop-loss to more Clients.
•Enhanced Sun Life Onboard, our fully digital benefits implementation tool for employers and brokers, with the launch of our Digital Smart Form.

                 MANAGEMENT'S DISCUSSION & ANALYSIS Sun Life Financial Inc. December 31, 2023 29


Strategy and Outlook
Our strategy is to be a leader in health and benefits in the U.S. that helps members access the care and coverage they need. The
US$4.5 trillion and growing health and benefits ecosystem is complex and rapidly changing. Health care staffing shortages and increasing demand are reducing capacity in the U.S. health care system, making accessing care more challenging. Over 85%, or $7.2 billion, of our revenue now comes from health care products and services, and we are serving a key role as a connector in the health care system by helping our members get the right diagnoses, treatments, and benefits. We have significantly advanced our capabilities with our DentaQuest and PinnacleCare acquisitions, and the addition of clinical support initiatives in our disability business. We are a differentiated provider whose offerings complement core health insurance offerings from large U.S. health insurers. Our medical stop-loss and dental benefits businesses are leaders in their industry sectors, and our group life and disability benefits business is a top-10 provider. Through our dental business, we are also part of the large and growing government programs market that covers more than 160 million Americans.

Our digital tools and support services also make it easier to do business with us and close coverage gaps. We also continue to leverage our unique partnership capabilities to drive growth by delivering solutions to our more than 100 health plan and insurance industry partners to support their members.

Helping Clients access the health care and coverage they need
•Extend our leadership position in medical stop-loss and innovative risk management solutions for self-funded employers by continuing to deliver complementary health-adjacent offerings, including Health Navigator powered by PinnacleCare, to help members with serious conditions get the care they need, achieve better health outcomes, and reduce costs.
•Leverage DentaQuest's scale and expertise to provide quality oral health to all and help Americans live healthier lives, continue to grow in government programs, and become a leader in commercial dental through our leading capabilities.
•Focus employee benefits offerings on health and productivity through expanded and enhanced offerings across disability, absence, life, and supplemental health to provide income protection, fill gaps in coverage, and help Clients get the care they need so they can recover and get back to work and to their lives.
•Help employers comply with complex regulations and provide more Americans with access to paid family and medical leave.
•Drive growth in FullscopeRMS by leveraging our expertise, scale, and suite of turnkey solutions for insurance and health plan partners, to improve coverage for members.
Making care and benefits easier through digital solutions
•Expand our ability to integrate with other major platforms in the health and benefits ecosystem, delivering a better Client experience.
•Drive digital expansion through new capabilities and partnerships while leveraging existing assets to deliver predictive and personalized analytics to help Clients make decisions that are right for them.
•Leverage digital tools to increase Client interactions and virtual engagement, helping to better serve more members and deliver deeper insights for brokers and employers.
 Help In-force Management policy-owners achieve lifetime financial security, while effectively managing our operations
•Continue to provide excellent service to our individual insurance and annuity policy owners.
•Optimize the value of the business by implementing opportunities to improve profitability, including expense efficiencies and alternative investment strategies.
•Effectively manage risk and capital through reinsurance and via product offerings for converting or maturing policies.

Outlook
The U.S. health and employee benefits ecosystem is large and growing, with Clients becoming increasingly aware of the value of protection products and services. These markets remain competitive, and we are committed to growing profitably by leveraging our leadership positions, deep expertise, and new capabilities to extend further into the health benefits and services space in order to help Americans live healthier lives.

The strength of our U.S. business is reflected by the growth of our sales, revenues, and underlying net income in 2023. Significant enhancements to our products, systems, and digital capabilities over the past several years have contributed to our growth, in addition to our recent acquisitions.

We have a diversified business that served us well during the pandemic and is well-positioned for growth. While we have some short-term headwinds in Dental due to the state Medicaid redetermination process following the end of the federally declared Public Health Emergency, the business is growing, we have a strong new business pipeline, and the fundamentals remain strong. The DentaQuest integration remains on schedule, and we are on track to achieve our synergy targets. Health and Risk Solutions results have begun to moderate from pandemic-related performance but remain strong as we price our products responsibility, invest in health capabilities and leverage data analytics to differentiate our product and service offerings; this will enable us to continue to grow the business with strong profit margins. We are seeing significant improvements in Employee Benefits as COVID-19 impacts subside and the business benefits from ongoing pricing discipline, a strong focus on disability claims management, and investments in technology that have improved the Client experience and driven sales and strong persistency.

We continue to work with state and federal officials to increase access to benefits for our Clients. In addition to our focus on paid family and medical leave, we have increased our advocacy to expand dental coverage for beneficiaries of Medicaid and other government programs, and to keep employer-sponsored dental benefits affordable. We are also supporting the ERISA Advisory Council’s recommendation that Congress pass legislation to ensure mental health parity in long-term disability insurance, which is already required for health insurance. We continue to monitor possible legislative and regulatory changes to key areas that impact our business, such as data security and privacy, minimum loss ratios for employer-sponsored dental insurance plans, and state government contractor requirements.

Profitability
2023 vs. 2022
Underlying net income of US$663 million increased US$132 million or 25%, driven by:
•Group - Health & Protection up US$118 million: Strong premium growth across all businesses, contribution from the DentaQuest acquisition, and higher net investment results including higher earnings on surplus reflecting an increase in net interest income from higher rates. Experience in the year included favourable margins in medical stop-loss and favourable group disability morbidity, partially offset by unfavourable dental experience primarily reflecting the impact of Medicaid redeterminations following the end of the Public Health Emergency, and group mortality. Mortality improved significantly when compared to pandemic-related experience in the prior year.
•Individual - Protection up US$14 million: The inclusion of the UK payout annuity business(1) and improved mortality experience, partially offset by lower net investment results.

Reported net income of US$440 million increased US$36 million or 9%, driven by the increase in underlying net income, partially offset by ACMA impacts. The prior year included a gain on the sale-leaseback of the Wellesley office which was partially offset by a charge reflecting the resolution of a matter related to reinsurance pricing for the In-force Management business.

Foreign exchange translation led to an increase of $31 million and $26 million in underlying net income and reported net income, respectively.

Growth
2023 vs. 2022
U.S. group sales of US$1,680 million were up US$216 million or 15%, driven by higher Dental(2) sales in Medicare Advantage, Medicaid, and commercial dental, as well as higher medical stop-loss sales, partially offset by lower employee benefits sales.












(1)On April 3, 2023, we completed the sale of SLF of Canada UK Limited to Phoenix Group Holdings plc ("the sale of Sun Life UK"). Under the agreement, we will retain our economic interest in the payout annuities business through a reinsurance treaty, which, effective Q2'23 is recorded in In-force Management within the U.S. business group. For additional information, refer to Note 3 of our 2023 Annual Consolidated Financial Statements.

Strategy and Outlook
We are dedicated to building distribution excellence and offering a seamless, digital experience for Clients and advisors to deliver Client impact.

We will embed sustainability into our business, as we engage Clients along their journeys towards lifetime financial security and healthier lives. Our areas of focus for Asia are to:

Deliver on bancassurance, sustainably grow agency, embed quality and optimize distribution mix
•Build sustainable scale through a diversified mix of high performing, quality-focused channels that enhance Client impact by offering holistic sales advice delivered through our expanding range of life, wealth and health solutions.

Outlook
Our diversified business, with a multi-country presence and multi-channel distribution, positions us well to deepen Client relationships, capture opportunities as they arise, and protects against adverse economic cycles and regulatory changes in any one market. Despite short-term headwinds from market volatility, we expect that the region’s economic growth will continue, and rapid wealth creation, coupled with low insurance penetration rates, will result in sustained growth across all our markets over the medium-term. In addition, we expect to continue to reach more Clients by expanding and deepening our high-quality agency force, diverse network of bancassurance partners and broker partnerships. We are confident that our position among the global leaders in the HNW space will continue to generate value and positive outcomes for Clients.

Economic and geopolitical uncertainty, as well as intense competition, equity market downturn, rise in interest rates and inflation continue to pose challenges to our businesses. However, our steadfast dedication to our Purpose and our Clients, strengthening market positions, key strategic relationships, investments in digital and analytics, and our ability to leverage Sun Life's global expertise position us well for the future. As local governments continue to push responsibility down to their people in both the retirement and health spaces, we are well-equipped to offer current and prospective Clients a diverse range of products and solutions.

(3)In underlying net income by business type, Group businesses in Asia have been included with Individual – Protection.

Profitability
2023 vs. 2022
Underlying net income of $600 million increased $61 million or 11%, driven by:
•Wealth & asset management down $16 million: Lower earnings largely in the Philippines and Hong Kong.
•Individual - Protection up $108 million: Business growth reflecting good sales momentum, improved mortality, and contributions from joint ventures primarily driven by favourable policyholder behaviour and expense experience, partially offset by lower earnings on surplus.
•Regional office expenses & other $(31) million increased net loss primarily reflecting continued pan Asia investments in the business.

Reported net income of $511 million increased $301 million, driven by market-related impacts, the increase in underlying net income, the impact from the Bermuda Corporate Income Tax Change(1), and ACMA impacts. Market-related impacts were primarily driven by the steepening of the interest rate curve, partially offset by real estate experience.
Foreign exchange translation led to an increase of $9 million and $17 million in underlying net income and reported net income, respectively.

(1)On December 27, 2023, Bermuda enacted its Corporate Income Tax Act 2023, which will apply a 15% income tax beginning on January 1, 2025 ("Bermuda Corporate Income Tax Change"). The enacted legislation provides an economic transition adjustment that aligns an entity’s starting point for the tax regime more closely with its economic position prior to the application of the Corporate Income Tax 2023. The benefit of this economic transition adjustment has been recognized in 2023. As a result, reported net income increased by $51 million in the fourth quarter, reflected in Other adjustments.
(2)This change excludes the impacts of foreign exchange translation. For more information about these non-IFRS financial measures, see section

Dah Sing Bank Bancassurance Partnership
Effective July 1, 2023 we commenced our 15-year exclusive bancassurance partnership with Dah Sing Bank ("Dah Sing"). Under this
partnership, Sun Life will be the exclusive provider of life insurance solutions to Dah Sing's approximately 570,000 retail banking customers, helping to fulfill their savings and protection needs at different life stages.

Profitability
2023 vs. 2022
Underlying net loss was $377 million compared to underlying net loss of $169 million in the prior year, driven by the sale of Sun Life UK, higher operating expenses, and an increase in debt financing costs, partially offset by higher investment income from surplus assets.

Reported net loss was $320 million compared to reported net loss of $260 million in the prior year, reflecting the change in underlying net loss and the prior year impact of tax-related matters(1), partially offset by the impacts from the sale of Sun Life UK.

Sale of Sun Life UK
On April 3, 2023 we completed the sale of SLF of Canada UK Limited ("Sun Life UK") to Phoenix Group Holdings plc ("Phoenix Group") for approximately $418 million. Sun Life UK managed life and pension policies as well as payout annuities for UK Clients, was closed to new sales and operated as a run-off business since 2001. Under the agreement, we will retain our economic interest in the payout annuities business through a reinsurance treaty, which, effective Q2'23, is recorded in In-force Management within the U.S. business group. Phoenix Group is the UK's largest long-term savings and retirement business, with £269 billion(2) of assets under administration and approximately 12 million customers(2). As part of the sale, we will establish a long-term partnership to become a strategic asset management partner to Phoenix Group. Our asset management companies, MFS and SLC Management, will continue to manage approximately $8 billion of Sun Life UK's general account. In addition, Phoenix Group has set a goal to invest approximately US$25 billion in North American public and private fixed income and alternative investments over the next five years. MFS and SLC Management will be material partners to Phoenix Group in achieving this goal. In Q3'22, we recognized an impairment charge pertaining to the attributed goodwill that was not expected to be recovered through the sale. In Q2'23, we recognized a gain of $19 million in reported net income. For additional information, refer to Note 3 of our 2023 Annual Consolidated Financial Statements.

I. Investments
The Company strives to ensure that general fund investments are aligned with business objectives including meeting policyholder obligations and maintaining adequate liquidity at all times. Consideration is given to a wide range of factors in our investment process, including ensuring attractive risk and return profiles, appropriate diversification by asset type, credit exposure and sector, financial condition and ESG profile of issuers and borrowers, quality and value of underlying security and macro- and micro-economic developments and trends including prospects for specific industry sectors. The Risk Committee of the Board of Directors ("Risk Committee") approves policies that contain prudent standards and procedures for the investment of our general fund assets. These policies include requirements, restrictions and limitations for interest rate, credit, equity market, real estate market, liquidity, concentration, currency, and derivative risks. Compliance with these policies is monitored on a regular basis and reported annually to the Risk Committee. The Governance, Investment & Conduct Review Committee of the Board of Directors monitors the Company's Investment Plan and investment performance, oversees practices, procedures and controls related to the management of the general fund investment portfolio, and reviews corporate governance guidelines and processes.

1. Investment Profile
Total general fund invested assets of $174.3 billion as at December 31, 2023, were up $5.5 billion from December 31, 2022. The increase was primarily due to net fair value growth from declining interest rates. Our general fund invested assets are well-diversified across investment types, geographies and sectors with the majority of our portfolio invested in high quality fixed income assets.

The following table sets out the composition of our general fund invested assets:(1)
December 31, 2023 December 31, 2022
($ millions) Carrying value % of Total carrying value Carrying value % of Total carrying value
Cash, cash equivalents and short-term securities 13,173 8% 11,219 7%
Debt securities 75,493 43% 75,902 45%
Equity securities 7,138 4% 7,148 4%
Mortgages and loans 54,600 31% 51,253 30%
Derivative assets 2,183 1% 2,095 1%
Other invested assets
12,018 7% 11,070 7%
Investment properties 9,723 6% 10,102 6%
Total invested assets 174,328 100% 168,789 100%

(1)The values and ratios presented are based on the fair value of the respective asset categories. Generally, the carrying values for invested assets are equal to their fair values. For invested assets supporting insurance contracts, in the event of default, if the amounts recovered are insufficient to satisfy the related insurance contract liability cash flows that the assets are intended to support, credit exposure may be greater than the carrying value of the assets.

2. Debt Securities
The debt securities portfolio is actively managed through a regular program of purchases and sales aimed at optimizing yield, quality, and liquidity, while ensuring that it remains well-diversified and duration-matched to insurance contract liabilities. As at December 31, 2023, with the exception of certain countries where we have business operations, including Canada, the United States and the Philippines, our exposure to debt securities from any single country did not exceed 1% of total invested assets.

December 31, 2023 (December 31, 2022 - 53%). While we generally limit the maximum loan-to-value ratio to 75% at issuance, we may invest in mortgages with a higher loan-to-value ratio in Canada if the mortgage is insured by the Canada Mortgage and Housing Corporation ("CMHC"). The estimated weighted average debt service coverage for our uninsured commercial portfolio is 1.75 times. Of the $3.8 billion of multi-family residential mortgages in the Canadian commercial mortgage portfolio, 93% were insured by the CMHC.

5. Derivatives
The fair value of derivative assets held by the Company was $2,183 million, while the fair value of derivative liabilities was $1,311 million as at December 31, 2023 (December 31, 2022 - $2,095 million and $2,351 million, respectively).

We use derivative instruments to manage risks related to interest rate, equity market and currency fluctuations and in replication strategies to reproduce permissible investments. Use of derivatives in these risk mitigation strategies does not mitigate all risk exposure; rather, they are used to keep us within our risk tolerance limits.

In addition to the general policies and monitoring, we use a variety of tools in counterparty risk management. Over-the-counter ("OTC") derivative transactions are executed under International Swaps and Derivatives Association ("ISDA") Master Agreements. A Credit Support Annex accompanies most of the ISDAs, which establish requirements for collateral.

Derivative Financial Instruments
The values associated with our derivative instruments are presented in the following table. Notional amounts serve as the basis for payments calculated under derivatives contracts and are generally not exchanged.
($ millions) December 31, 2023 December 31, 2022
Net fair value asset (liability) 872 (256)

Credit equivalent amount(1)
1,594  1,173 
Risk-weighted credit equivalent amount(1)

(1)Amounts presented are net of collateral received.

The net fair value of derivatives was an asset of $872 million as at December 31, 2023 (December 31, 2022 - liability of $256 million). The increase in net fair value was driven by an increase in interest rate contracts due to downward shifts in yield curves and an increase in foreign exchange contracts due to the strengthening of the Canadian dollar against U.S. dollar.

The total notional amount of our derivatives increased to $70.4 billion as at December 31, 2023 (December 31, 2022 - $69.8 billion). The change in notional amount is mainly attributable to an increase in foreign exchange contracts used for hedging foreign currency assets.

Certain of our derivatives are designated in qualifying hedging relationships for accounting purposes, and represented $1.0 billion, or 1.5% of the total notional amount. Derivatives are designated in hedging relationships for accounting purposes to minimize accounting mismatches. These hedging relationships are documented at inception and hedge effectiveness is assessed on a quarterly basis.

Derivatives designated in qualifying hedging relationships for accounting purposes include foreign exchange agreements and equity forwards. We designate certain foreign exchange agreements in cash flow hedging relationships to manage foreign currency fluctuations associated with FVOCI assets. Additionally, we designate certain equity forwards in cash flow hedging relationships for anticipated payments of awards under certain stock-based compensation plans.

Credit Equivalent Amount
As the regulator of the Canadian insurance industry, OSFI provides guidelines to quantify the use of derivatives. The credit equivalent amount ("CEA"), a measure used to approximate the potential credit exposure, is determined as the replacement cost of the derivative contracts with a positive fair value plus an amount representing the potential future credit exposure.











44 December 31, 2023 Sun Life Financial Inc. MANAGEMENT'S DISCUSSION & ANALYSIS The risk-weighted credit equivalent amount is a measure used to determine the amount of capital necessary to support derivative transactions for certain Canadian regulatory purposes.


It is determined by weighting the credit equivalent amount according to the nature of the derivative and the creditworthiness of the counterparties.

Credit Default Swaps By Underlying Financial Instrument Credit Rating
Credit default swaps ("CDS") are derivative contracts that transfer credit risk related to an underlying referenced financial instrument from one counterparty to another. The purchaser receives protection against the decline in the value of the referenced financial instrument as a result of specified credit events such as default or bankruptcy. The Company sells credit protection through CDS to replicate credit exposure of an underlying reference security and enhance investment returns. The credit risk ratings of the underlying reference securities for single name contracts were established in accordance with the internal rating process described in section K - Risk Management - 9 - Risk Categories - Credit Risk Management Governance and Control.

The following table provides a summary of the credit default swap protection sold by credit rating of the underlying reference security.

6. Investment Properties
As at December 31, 2023, we held $9.7 billion of investment properties (December 31, 2022 - $10.1 billion). The decrease in our investment property portfolio is predominantly driven by declines in market value, mainly in the office sector, and property sales in the industrial sector.

The balance of the total loss allowance was $89 million as at December 31, 2023 (January 1, 2023(1) - $75 million) and the provision for credit losses was $14 million for the year ended December 31, 2023.

J. Capital and Liquidity Management
Capital and liquidity management is core to our business as an insurance company. We ensure adequate capital for the protection of our policyholders, Clients and creditors, while managing capital adequacy and allocation across our businesses for the benefit of our shareholders. In addition, we maintain strong financial flexibility by ensuring that sufficient liquid assets are available to cover our anticipated payment obligations and funding requirements. We invest in various types of assets with a view to matching them with liabilities of various durations.

The regulatory environments in which we operate are expected to evolve as governments and regulators work to develop the appropriate level of financial regulation required to ensure that capital, liquidity and risk management practices are sufficient to withstand severe economic downturns.

1. Capital
We have a capital risk policy designed to maintain a strong capital position and to provide the flexibility necessary to take advantage of growth opportunities, to support the risk associated with our businesses and to optimize shareholder return. Our capital risk policy is also intended to provide an appropriate level of risk management over capital adequacy risk, which is defined as the risk that capital is not or will not be sufficient to withstand adverse economic conditions, to maintain financial strength, or to allow the Company and its subsidiaries to take advantage of opportunities for expansion. Our capital base is structured to exceed minimum regulatory and internal capital targets and to maintain strong credit and financial strength ratings, while maintaining a capital-efficient structure. Capital is managed both on a consolidated basis under principles that consider all the risks associated with the business as well as at the business group level under the principles appropriate to the jurisdictions in which we operate. The capital of our foreign subsidiaries is managed on a local statutory basis in a manner commensurate with their individual risk profiles.

Sun Life, including all of its business groups, engages in a capital planning process annually in which capital deployment options, capital raising and dividend recommendations are presented to the Board of Directors ("Board"). Capital reviews are regularly conducted which consider the potential impacts under various business, interest rate and equity market scenarios. Relevant components of these capital reviews, including dividend recommendations, are presented to the Risk Committee on a quarterly basis. The Board is responsible for the approval of our annual capital plan and quarterly shareholder dividends.

The Company's capital risk policy establishes policies, operating guidelines and procedures that govern the management of capital. The capital risk policy is reviewed annually by the Risk Committee and any changes are approved by the Board. Our Corporate Capital and Risk Management functions are responsible for the development and implementation of the capital risk policy.

The Company's capital base consists mainly of common shareholders' equity. Other sources of capital include preferred shares and other equity instruments, non-controlling interests, equity in the participating account, CSM, subordinated debt issued by SLF Inc. and Sun Life Assurance, and certain other capital securities that qualify as regulatory capital. For Canadian regulatory purposes, our capital also includes innovative capital instruments issued by Sun Life Capital Trust.



























(1)For financial assets in which the impairment requirements of IFRS 9 applies, we have elected to continue presenting the loss allowance that was determined in accordance with IAS 39 for balances at December 31, 2022. For additional information, refer to Note 2 in our 2023 Annual Consolidated Financial Statements.

(1)This measure has not been restated for periods in 2022 and earlier as IFRS 17 and IFRS 9 were not the accounting standards in effect, and therefore were not applicable to our capital management practices at the time.
(2)Effective January 1, 2023, total capital was updated to include the CSM balance.
(3)Innovative capital instruments are presented net of associated transaction costs and consist of SLEECS, which were issued by Sun Life Capital Trust. SLEECS qualify as capital for Canadian regulatory purposes. However, under IFRS they are reported as Senior debentures in our Consolidated Financial Statements.
(4)Common shareholders’ equity is equal to Total shareholders’ equity less Preferred shares and other equity instruments.
(5)Effective January 1, 2023, the calculation for the financial leverage ratio was updated to include the CSM balance (net of taxes) in the denominator. The CSM (net of taxes) was $9.6 billion as at December 31, 2023 (January 1, 2023 - $8.7 billion).
(6)Represents a non-IFRS financial measure. See section M - Non-IFRS Financial Measures in this document.

Our total capital consists of subordinated debt and other capital instruments, participating policyholders' equity, non-controlling interests and total shareholders' equity, which includes common shareholders' equity, preferred shares and other equity instruments.

On transition to the new standards, Common shareholders' equity of $20.3 billion as at January 1, 2023 decreased $4.9 billion compared to December 31, 2022 primarily driven by the establishment of the CSM, which includes transfers from Common shareholders' equity and equity in the participating account to the CSM.

Common shareholders' equity was $21.3 billion as at December 31, 2023 (January 1, 2023 - $20.3 billion), an increase of $1.1 billion in 2023 primarily due to common shareholders' net income, partially offset by dividends, a decrease of $186 million from the repurchase and cancellation of common shares and the impact related to the AAM acquisition of $156 million(1). For additional information about the change in common shareholders' equity from the adoption of IFRS 17 and IFRS 9, refer to Note 2.A in our 2023 Annual Consolidated Financial Statements.

Under our Canadian Dividend Reinvestment and Share Purchase Plan ("DRIP"), Canadian-resident common and preferred shareholders may choose to have their dividends automatically reinvested in common shares of SLF Inc. and may also purchase common shares through our DRIP with cash. For dividend reinvestments, we may, at our option, issue common shares of SLF Inc. from treasury at a discount of up to 5% to the volume-weighted average trading price or direct that common shares be purchased on behalf of participants on the open market through the TSX and alternative Canadian trading platforms (collectively, the "Exchanges") at the market price. Common shares of SLF Inc. acquired by participants through optional cash purchases may also be issued from treasury or purchased through the Exchanges at SLF Inc.'s option, in either case at no discount. Commencing with the dividends payable on March 31, 2016 and until further notice, common shares purchased under the Plan were purchased on the open market. There are no applicable discounts because the common shares are being purchased on the open market and are not being issued from treasury.

SLF Inc. grants stock options to certain employees. These options are granted at the closing price of SLF Inc.'s common shares on the TSX on the grant date.

As at January 26, 2024, SLF Inc. had 584,631,371 common shares, 3,428,382 options to acquire SLF Inc. common shares, and 52,200,000 Class A Shares outstanding.

2. Capital Adequacy
OSFI has indicated that it will review the effectiveness of the LICAT guideline and update it to keep abreast of development in the life insurance industry and evolving risk measurement and management practices.

SLF Inc.
SLF Inc. is a non-operating insurance company and was subject to OSFI's LICAT guideline as at December 31, 2023. In accordance with this guideline, SLF Inc. manages its capital in a manner commensurate with its risk profile and control environment, and SLF Inc.'s regulated subsidiaries comply with the capital adequacy requirements imposed in the jurisdictions in which they operate. SLF Inc.'s consolidated capital position is above its internal target. As at December 31, 2023, SLF Inc.'s LICAT ratio was 149%. For additional information, refer to section G - Financial Strength in this document.

Sun Life Assurance
Sun Life Assurance, SLF Inc.'s principal operating life insurance subsidiary in Canada, was subject to OSFI's LICAT guideline as at December 31, 2023. With a LICAT ratio of 141% as at December 31, 2023, Sun Life Assurance's capital ratio is well above OSFI's supervisory ratio of 100% and regulatory minimum ratio of 90%. The LICAT guideline uses a risk-based approach for measuring specific life insurer risks and for aggregating the results to calculate the amount of a life insurer's regulatory required capital to support these risks. Certain of these risk components, along with available capital, are sensitive to changes in equity markets and interest rates as outlined in the section K - Risk Management of this document. For additional information, refer to section G - Financial Strength in this document.

                 MANAGEMENT'S DISCUSSION & ANALYSIS Sun Life Financial Inc. December 31, 2023 49

(1)OSFI's 2023 LICAT Guideline, effective January 1, 2023, specifies that available capital for LICAT purposes includes the Contractual Service Margin. Prior period restatement and resubmissions are not mandated.

Foreign Life Insurance Companies
Foreign subsidiaries and foreign operations of SLF Inc. must comply with local capital or solvency requirements in the jurisdictions in which they operate. Our operations maintained capital levels above the minimum local regulatory requirements during 2023 and 2022. Additional information on capital and regulatory requirements for our foreign subsidiaries and foreign operations is provided in SLF Inc.'s AIF under the heading Regulatory Matters.

As at December 31, 2023, we have two internal reinsurance arrangements with affiliated reinsurance companies, in Delaware and Michigan, relating to our closed block of individual universal life insurance products with no-lapse guarantee benefits issued in the U.S. The Delaware reinsurance structure was established in 2013 and finances excess U.S. statutory reserves for certain universal life policies issued between January 2000 and February 2006. The financing of U.S. statutory reserve requirements in excess of those required under IFRS for the Delaware reinsurance company is supported by a guarantee from SLF Inc. The Michigan reinsurance structure was established in 2007 for certain policies issued between March 2006 and December 2008. The entity was redomesticated from Vermont to Michigan in 2020. Under the Michigan reinsurance structure, the related excess U.S. statutory reserve requirements are similarly supported by a guarantee from SLF Inc.

3. Shareholder Dividends
The declaration, amount and payment of dividends by SLF Inc. is subject to the approval of our Board and is dependent on our results of operations, our reported net income, financial condition, cash requirements and contractual restrictions. Capital management activities, as well as regulatory considerations and macro-economic factors including the economic outlook for the jurisdictions in which we do business, are also considered along with other factors. The Board reviews the level of dividends on a quarterly basis.

A regular and appropriate level of dividend payout and growth provides a stable source of return to common shareholders.

We target an underlying dividend payout ratio of between 40% and 50% based on underlying EPS.

During 2023, our dividend payout ratio to common shareholders based on our underlying EPS basis was 47% and on reported EPS was 57%.

Total common shareholder dividends declared in 2023 were $3.00 per share, compared to $2.76 in 2022.

4. Principal Sources and Uses of Funds
Our primary source of funds is cash provided by operating activities, including premiums, investment management fees and net investment income. These funds are used primarily to pay policy benefits, dividends to policyholders, claims, commissions, operating expenses, interest expenses and shareholder dividends. Excess cash flows generated from operating activities are generally invested to support future payment requirements. We also raise funds from time to time, through borrowing and issuing of securities, to finance growth, acquisitions or other needs.

As at December 31, 2023, we maintained net cash, cash equivalents and short-term securities totaling $13.2 billion. In addition to providing for near-term funding commitments, cash, cash equivalents and short-term securities include amounts that support short-term payment obligations.

Net cash, cash equivalents and short-term securities increased $2.0 billion. The table below outlines our principal sources and uses of cash.

5. Liquidity
We generally maintain an overall asset liquidity profile that exceeds requirements to fund insurance contract liabilities under prescribed adverse liability demand scenarios. To strengthen our liquidity further, we actively manage and monitor our:
•Capital levels
•Asset levels
•Matching position
•Diversification and credit quality of investments
•Cash forecasts and actual amounts against established targets

We are subject to various regulations in the jurisdictions in which we operate. The ability of SLF Inc.'s subsidiaries to pay dividends and transfer funds is regulated in certain jurisdictions and may require local regulatory approvals and the satisfaction of specific conditions in certain circumstances. Through effective cash management and capital planning, SLF Inc. ensures that its subsidiaries, as a whole and on a stand-alone basis, are properly funded and maintain adequate liquidity to meet obligations, both individually and in aggregate.

SLF Inc. (the ultimate parent company) and its wholly-owned holding companies had $1.6 billion in cash and other liquid assets(1) as at December 31, 2023. See section G - Financial Strength and M - Non-IFRS Financial Measures in this document for more information.

We maintain various credit facilities for general corporate purposes, as set out in the table below. Unless otherwise noted, all amounts are in Canadian dollars.
($ millions) December 31, 2023 December 31, 2022
Credit Facility Amount Utilized Expiry Amount Utilized Expiry
Committed US $ 400  US $ 11  2025 US $ 400  US $ 11  2025
Committed US $ 1,710  US $ 1,384  2024 US $ 1,950  US $ 1,358  2024
Committed $ 500  $ 500  2025 $ 500  $ 500  2025
Uncommitted US $ 100  US $ —  n/a US $ 100  US $ —  n/a
Uncommitted $ 229  $ 95  n/a $ 227  $ 89  n/a
Uncommitted US $ 25  US $ n/a US $ 25  US $ n/a
The agreements relating to our committed credit facilities contain typical covenants for investment grade companies regarding solvency, credit ratings and financial strength, all of which were met as at December 31, 2023. These covenants include, but are not limited to, the maintenance of total equity by SLF Inc. of at least $12 billion, tested as of the last day of each fiscal quarter. SLF Inc.'s total equity was $24.2 billion as at December 31, 2023.

Our failure to comply with the covenants under the committed credit facility would, subject to grace periods in the case of certain covenants, result in an event of default. This could require us to repay any outstanding borrowings or to cash collateralize letters of credit under the facility. A failure by SLF Inc. (or any of its subsidiaries) to pay an obligation due for an amount exceeding $250 million would also result in an event of default under the committed credit facility described above.

Based on our historical cash flows and liquidity management processes, we believe that the cash flows from our operating activities will continue to provide sufficient liquidity for us to satisfy debt service obligations and to pay other expenses as they fall due.

52 December 31, 2023 Sun Life Financial Inc. MANAGEMENT'S DISCUSSION & ANALYSIS The Company has an established Risk Management Framework ("Risk Framework") approved by the Board that prescribes a comprehensive set of protocols and programs that need to be followed in conducting business activities.


K. Risk Management
1. Risk Management Framework
The risks that arise when providing products and services to Clients, which are in line with our Purpose to help our Clients achieve lifetime financial security and live healthier lives, are managed within these protocols and programs. Effective risk management is critical to the overall profitability, competitive market positioning and long-term financial viability of the Company. While all risks cannot necessarily be eliminated or known with certainty, the Risk Framework seeks to ensure that risks to a business undertaking are appropriately managed to achieve the Company's business objectives over time and are not expected to exceed pre-established boundaries for risk taking. The Risk Framework, corporate strategy and business objectives are all aligned and risk management protocols and programs are embedded within every business segment.

2. Risk Governance and Accountabilities
Our Risk Framework sets out lines of responsibility and authority for risk-taking, governance and control. These governance requirements are summarized below.

riskgovernancestructure-ena.jpg

Board of Directors
The Board is responsible for ensuring the governance of all risks across the enterprise and has primary responsibility for taking action to ensure risk management policies, programs and practices are in place. By approving our Risk Framework and the Risk Appetite Policy and providing ongoing oversight of the risk management programs, the Board monitors that significant risks are appropriately identified and managed. The Board oversees business and strategic risk through review and approval of the Business and Strategic Plans, and regularly discusses key themes, issues and risks arising in connection with the design or implementation of these plans.

The Risk Committee is a standing committee of the Board whose primary functions are to assist the Board with oversight of the management of current and emerging risks enterprise-wide, and of the Risk Management function to ensure that management has in place programs, policies, processes and controls designed to identify and effectively manage the significant risks to which the Company is exposed and has sufficient capital to underpin those risks. It reviews and approves all risk management policies and reviews compliance with those policies. In addition, where the Board has delegated risk oversight to other committees of the Board ("Board Committees"), the Risk Committee provides the Board with an integrated view of oversight of risk management across all Board committees. The Risk Committee regularly monitors the Company's risk profile to ensure it is within the agreed risk appetite and that the Company's capital position exceeds regulatory capital requirements, and monitors and recommends to the Board for approval, the specific risk limits allocated to the businesses and the annual Capital Plan. The Risk Committee also oversees risk management activities of our subsidiaries and joint ventures under the Company's management control and risks posed to the Company through its other joint ventures.

The Governance, Investment & Sustainability Committee (“GISC”) of the Board is responsible for assisting the Board in overseeing (i) the development of effective corporate governance guidelines and processes, including those addressing the effectiveness of the Board and its committees and director succession planning and recruitment; (ii) the Company's Investment Plan and investment performance, including investment practices, procedures and controls related to the management of the general fund investment portfolio; (iii) sustainability matters including the Company's Sustainability Policy, Sustainability Report and Sustainability Plan; and (iv) compliance and compliance management programs, including compliance with legal and regulatory requirements, the identification and management of compliance risk, and the
54 December 31, 2023 Sun Life Financial Inc. MANAGEMENT'S DISCUSSION & ANALYSIS development of policies and processes to sustain ethical behaviour.


GISC also serves as the conduct review committee of the Company in accordance with applicable provisions of the Insurance Companies Act (Canada).

The Audit Committee of the Board is responsible for assisting the Board in overseeing the integrity of financial statements and related information provided to shareholders and other stakeholders, compliance with financial regulatory requirements, adequacy and effectiveness of the internal controls implemented and maintained by management, and assessing the qualifications, independence and performance of the external auditor.

The Management Resources Committee of the Board is responsible for assisting the Board with oversight of succession planning for senior executive positions and programs to effectively attract, retain, develop and reward employees. It provides guidance to management on advancing the talent agenda to achieve strategic objectives and foster the Company's culture. The Committee reviews incentive designs and governance of material incentive programs against alignment with business objectives and avoiding excessive risk taking. It reviews the implications of key enterprise risks, including people and culture risks pertaining to compensation design and human resources practices. In addition, the Committee reviews compensation matters, including the remuneration of executives who have a material impact on the risk exposure of the Company.

Senior Management Committees
The Executive Risk Committee ("ERC") provides executive management oversight of the Company's enterprise risk management activities. This includes the review and articulation of the risk appetite, overseeing that the risk profile is within the agreed risk appetite, and overseeing that there are policies, processes and controls are in place to identify and effectively manage the significant risks, in accordance with the risk appetite and the overall objective of promoting a balanced business and product model to achieve agreed upon risk-adjusted returns and allocate capital accordingly.

The Investment & Credit Risk Committee is responsible for reviewing critical matters related to the on-going management of the Company's General Fund. Accordingly, the Committee is responsible for overseeing, monitoring and reviewing current and potential credit and investment risk exposures, other credit and investment risk management issues and future credit and investment risk management strategies.

The Corporate Asset Liability Management Committee is responsible for providing oversight and input on the Asset Liability Management framework, policies, guidelines, limits, measurement and performance assessment applicable to the management of market and liquidity risks, as well as providing oversight of asset liability management and hedging strategy changes.

The Operational Risk & Compliance Committee is responsible for providing oversight of the Company's operational and compliance risk management practices, current and emerging operational risk exposures, and the processes to ensure ongoing identification of major operational and compliance risks facing the Company.

The Insurance Risk Committee is responsible for providing oversight and direction on insurance risk exposures facing the Company and to ensure that effective insurance risk management practices and controls are in place. This includes reviewing the current and emerging insurance risk profile; engaging in review of topical insurance, reinsurance and underwriting risk issues; and reviewing and recommending changes to the insurance risk measurement methodology.

Accountabilities
Primary accountability for risk management is delegated by the Board to our Chief Executive Officer ("CEO"). The CEO further delegates responsibilities throughout the Company through management authorities and responsibilities. The CEO delegates accountability for the various classes of risk management to our executive officers, who are accountable for ensuring that the management of risk in the scope of their business accountability is in accordance with the Board approved Risk Framework, Risk Appetite Policy and risk management policies.

3. Risk Universe
As a large financial services organization operating in a complex industry, the Company encounters a variety of risks and uncertainties. We face risks in formulating our business strategy and business objectives, in carrying on our business activities in the pursuit of our strategy and objectives, and from external factors such as changes in the economic, geopolitical, environmental, social and regulatory landscape. We are subject to financial and insurance risks that are connected to our liabilities and with the management and performance of our assets, including how we match returns from assets with the payment of liabilities to our Clients. Each of these risks is also considered from the perspective of different types of uncertainties under which either the outcomes and/or their probabilities of occurrence are unknown. The Risk Framework covers all risks and these have been grouped into six major categories: business and strategic, credit, market, liquidity, insurance and operational risks. The Risk Framework sets out the key risk management processes in the areas of risk: appetite, identification, measurement, management, monitoring and reporting. The Risk Framework sets out both qualitative and quantitative measures and processes to control the risk the Company will bear in respect of each of these categories of risk and in aggregate.

4. Risk Appetite
Our Risk Appetite Policy defines the amount and type of risk we are willing to accept in pursuit of our business objectives, and is approved by the Board. It is forward-looking and our Strategic Plan, Capital Plan, Business Plan and business objectives are established within its boundaries.

The Company's risk appetite seeks to balance the various needs, expectations, risk and reward perspectives and investment horizons of all stakeholders. In particular, our risk appetite supports the pursuit of shareholder value while ensuring that the Company's ability to pay claims and fulfill policyholder commitments is not compromised.

The Company's risk appetite is the primary mechanism to operationalize its risk philosophy and the boundaries of permissible risk-taking across the enterprise. It ensures that business activities are assessed against performance criteria that are appropriately risk-adjusted. Our risk appetite supports the objective of maintaining adequate capital, managing earnings volatility, managing operational risk and managing
                 MANAGEMENT'S DISCUSSION & ANALYSIS Sun Life Financial Inc. December 31, 2023 55


liquidity. To accomplish this, our risk appetite includes a wide array of qualitative and quantitative standards that reflect the Company's overall risk management principles and values.

We are generally comfortable accepting diversifiable risks where we are capable of using risk pooling to create liability portfolios with relatively low volatility. We take risk where we have internal expertise such as actuarial, underwriting, claims management, investment, risk management and distribution or where reinsurance partners are able to supplement our internal expertise. We prefer risks that arise across various dimensions, including products, geographies (intra-national and international), distribution channels and asset classes in order to maximize diversification opportunities.

Our Risk Appetite Policy sets out specific constraints which define the aggregate level of risk that the Company is willing to accept. We translate our risk appetite constraints into specific risk limits by risk class and business segment. Our risk profile is measured, managed and monitored regularly to ensure that we operate within our risk appetite. Our risk appetite limits are reviewed periodically to reflect the risks and opportunities inherent in our evolving business strategies and operating environment.

5. Risk Management Policies
In order to support the effective communication, implementation and governance of our Risk Framework, we have codified our processes and operational requirements in a comprehensive series of risk management frameworks, policies and operating guidelines. These frameworks, policies and guidelines promote the application of a consistent approach to managing risk exposures across our global business platform. The Board and Board Committees regularly review and approve significant changes to the risk management framework and policies and regularly review management's reporting and attestation on compliance to these policies.

6. Risk Management Process
The risk management process as set out in our Risk Framework is described below:

Risk Identification and Measurement
All business segments employ a common approach to identify and measure risks. Business segments have accountability for identifying and managing risks facing their business. We have a process to identify and monitor key and emerging risks that may have a material impact on our finances, operations or reputation. We evaluate potential correlations and inter-connections between various risk events and categories, and monitor key and emerging risks, emerging regulatory and rating agency requirements, or industry developments and various research reports.

Risk measurement involves determining and evaluating potential risk exposures and includes a number of techniques, such as monitoring key risk indicators, probability-severity assessments, stress testing (including sensitivity and scenario analysis), reverse stress testing and stochastic modelling. Risk measures are expressed in quantitative and qualitative terms.

A robust stress testing program is an essential component of the Company's Risk Framework used to measure, monitor, understand and mitigate the Company's risk exposures and to ensure ongoing capital adequacy under plausible stress events. Stress testing is performed on key metrics such as earnings, regulatory capital ratios and liquidity to identify and monitor potential vulnerabilities to key risk drivers and ensure that the Company is operating within its risk appetite.

We develop and test a range of scenarios based on our internal assessment and regulatory guidance. Emerging risks are one of the inputs to determine stress test scenarios. Sensitivity testing is conducted on a regular basis and measures the earnings and regulatory capital and liquidity impacts from changes in underlying risk factors, assuming that there are no changes to any of the other risk factors. Sensitivity testing is performed for individual risks and for consolidated risk exposures at different levels of stress and at various levels of aggregation. Scenario testing involves changes to a number of risk factors to assess the impact of and interaction between these risk factors. These scenarios include integrated scenario testing, reverse scenario testing and key assumption sensitivity testing. We also use the Financial Condition Testing ("FCT") process, as prescribed by the Canadian Institute of Actuaries, to satisfy requirements under the Canadian insurance Company Act, and OSFI regulations, to annually stress test capital.

Risk Management, Monitoring and Reporting
Risk management decisions are formed by evaluating whether the assessed risk for a business activity aligns to our risk appetite and meets the objective of risk-adjusted returns.

Monitoring processes include oversight by the Board, which is exercised through Board Committees and Senior Management committees described in the Risk Governance and Accountabilities section in this document.

At least on a quarterly basis, the Senior Management committees, Board Committees and the Board review reports that summarize our risk profile against the Board approved risk appetite, including the exposures across our principal risks, any changes in risk trends, forward-looking view of risks and emerging risks. These committees also review the effectiveness of the risk management strategies presented in the reports. On a regular basis, the Board and the Board Committees review and approve any significant changes to risk management frameworks and policies for the management of risk and review compliance with these frameworks and policies.

7. Three Lines of Defence
The Company has adopted the Three Lines of Defence ("LOD") model to provide a consistent, transparent and clearly documented allocation of accountability and segregation of functional responsibilities. This segregation of responsibility helps to establish a robust control framework that promotes transparent and independent challenge of all risk taking activities, and that encourages all functions to engage in self-critical examination to foster continuous improvement of the management of risk in our business.

56 December 31, 2023 Sun Life Financial Inc. MANAGEMENT'S DISCUSSION & ANALYSIS The first line of defence is represented by the business segment management who own the risks that are intrinsic to the business and have the primary responsibility to identify, measure, manage, monitor and report these risks.


Some of the first LOD risk related responsibilities include:
•Identification of key and emerging risks;
•Manage, measure, monitor and report on risk within their business operations;
•Accountability for business results and the risks taken to achieve business results and the resulting impact of those risks; and
•Operating within risk appetite and according to risk management policies.

The second line of defence includes the Chief Risk Officer ("CRO") and heads of the oversight functions who are responsible for providing independent oversight of our Company-wide risk management programs. The CRO is responsible for developing our Risk Framework and Risk Appetite Policy, and for overseeing the development and implementation of risk management strategies aimed at optimizing the risk-return profile of the Company. The CRO is supported by a network of business segment risk officers. The functional heads support the CRO in the implementation and communication of our Risk Framework and Risk Appetite Policy. Some of the key second LOD risk related responsibilities include:
•Establishment of the risk management framework and policies;
•Providing oversight and effective independent challenge of first line; and
•Independent reporting to Senior Management committees and the Board of Directors on the level of risk against risk appetite.

The third line of defence responsibilities are distinct from first and second LOD responsibilities. The Internal Audit function is the third LOD and is responsible for providing independent assurance to Senior Management and the Board and/or Board Committees on the design and operational effectiveness of the risk management practices and internal controls carried out by first LOD and second LOD. Internal Audit provides a quarterly opinion on the effectiveness of internal controls, risk management and governance processes to the Audit Committee of the Board. In addition, the Risk Committee may engage third-party independent reviews to supplement the third LOD review of the effectiveness of the Company's risk management programs.

8. Risk Culture and Philosophy
We have built a strong corporate culture on a foundation of ethical behaviour, high business standards, integrity and respect. The Board establishes the "tone from the top" and is accountable to ensure that the CEO and Senior Management create and sustain a culture of integrity throughout the organization. We work together through our focus on diversity, equity and inclusion and sustainability to fulfill our Purpose of helping our Clients to achieve lifetime financial security and to live healthier lives.

Risk culture relates to how we behave and respond, in addition to the requirements we set. It enables and rewards taking the right risks in an informed manner. It enables effective challenge and transparency regarding risks and outcomes without fear of reprisal. It drives us to understand Client needs and preferences so that we can act in their best interests. In order to support employees in fulfilling their role, we have taken action to ensure our risk protocols and procedures are well defined and embedded in our day-to-day business activities, assess that appropriate resources and training are provided, establish and communicate a common risk philosophy and a high bar for integrity and conduct, and encourage every employee to openly identify risk exposures and communicate escalating risk concerns. The following seven elements support our Risk Culture:
•Establishing tone from the top;
•Encouraging transparency in risk-taking;
•Performing effective challenge in conducting business decisions;
•Aligning incentives and risk management practices;
•Effectively communicating the risk culture expectations;
•Establishing clear accountabilities; and
•Promoting ongoing resiliency

A key premise of our culture is that all employees have an important role to play in managing the Company's risks. Risk Management is embedded in the enterprise's culture, which encourages ownership and responsibility for risk management at all levels. Our compensation programs are aligned to the organization's risk management practices through our governance structure for the design and approval of incentive compensation plans and processes used to support the alignment of compensation and risk management. We continuously reinforce and embed the culture through communication and training on risk culture elements at various forums and across various levels through training on the Code of Conduct annually, reinforcing accountability through performance reviews and compensation, continually monitoring processes and outcomes that drive expected behaviours, and through defining roles, responsibilities and expectations in the risk management policies.

The Company's risk philosophy includes the following core principles:

Strategic Alignment
Our corporate strategy and business objectives are required to be established within the boundaries and prescriptions set out in the Risk Framework and the Risk Appetite Policy. This requires us to consider whether a business activity, intended to achieve the business and financial objectives, will result in a risk profile that we are willing to accept and which we are prepared to manage. We have established a range of explicit risk appetite constraints for credit, market, insurance, operational and liquidity risks. Business and strategic risk is managed through our strategic and business planning process and through controls over the implementation of these Strategic and Business Plans. Risks associated with activities outside our risk appetite or outside the acceptable defined risks are avoided.

Client and Other Stakeholder Interests
Our Risk Appetite Policy considers the interests of a large number of key stakeholders, including Clients, shareholders, debt-holders, employees, regulators, distributors, rating agencies and other capital markets participants. The policy prescribes how to balance the needs, expectations, risk and reward perspectives, and investment horizons of these different stakeholders.

Effective risk management requires that objectives and incentives be aligned to ensure management's decisions are consistent with the Company's risk philosophy and risk appetite. To ensure this, the Business Plans and strategies are independently tested to ensure that they
                 MANAGEMENT'S DISCUSSION & ANALYSIS Sun Life Financial Inc. December 31, 2023 57


operate within the boundaries and requirements set out in the Risk Framework and the Risk Appetite Policy, and the results of this testing are reported to the Board. Compensation programs for employees are approved by the Board and the Board Committees and are aligned with the Company's risk philosophy, values, business and risk management strategies, and the long-term interests of stakeholders. In establishing annual performance objectives, we consider risk management goals to ensure that business decisions are consistent with the desired risk and return profile of the Company.

Capability Alignment
We seek out profitable risk-taking opportunities in those areas where we have established risk management skills and capabilities. Conversely, we endeavour to avoid or transfer risks that are beyond our risk-taking capability. Our ability to measure and evaluate risks, the quality of our risk governance and control environment, the depth and quality of our risk responses and the robustness of our pricing strategies are particularly important capabilities that we assess.

Portfolio Perspective
In evaluating a particular risk, consideration is given to a portfolio perspective of risk and return including the explicit recognition of the impacts of diversification and concentration and how different risks interact with each other. This perspective is extended to the development of risk mitigation and pricing strategies, recognizing that often the most cost-effective way of managing risk involves utilizing available relationships already inherent in our businesses.

Risk-Adjusted Returns
Financial return metrics used to assess business activities are developed in consideration of the constraints set out in the Risk Appetite Policy, and reflect the expected costs of mitigation and the cost of risk capital required to support the risk taking activity.

Culture
Culture is the sum of the shared assumptions, values and beliefs that create the unique character of an organization. Our culture encourages behaviour aligned with goals for long-term value creation. It defines the appropriate behaviour for any given situation, governs the interaction with Clients and affects how employees identify with the organization. Our culture has significant potential to impact our risk profile. An organization's culture impacts its ability to create value and to protect value. Maintaining the right balance of risk-taking and risk control activities is a key organizational capability and fundamental to our long-term sustainable success.

Sustainability
Sustainability addresses the Company’s material economic, environmental and social impacts, and the opportunities and risks they present in delivering long-term value to all key stakeholders for the Company. Our sustainability ambition is to help our Clients achieve lifetime financial security, foster healthier lives and advance sustainable investing. Policies, processes and controls are in place to identify and effectively manage significant risks, including sustainability-related risks, to which we are exposed while operating within the Risk Appetite Policy. Sustainability is considered essential to long-term business success and as a result, is a priority for Sun Life in order to maximize our impact on society and create competitive advantage and differentiation for our business.

9. Risk Categories
The text and tables in the following section of this MD&A include our disclosure on credit, market and liquidity risks in accordance with IFRS 7 Financial Instruments - Disclosures ("IFRS 7") and IFRS 17 Insurance Contracts, as well as a discussion on how we measure risk and our objectives, policies and methodologies for managing these risks. Disclosures in accordance with IFRS 7 and IFRS 17 are identified by a vertical line in the left margin of the page. The identified text and tables represent an integral part of our audited Annual Consolidated Financial Statements for the year ended December 31, 2023. The fact that certain text and tables are identified with a vertical line does not imply that these disclosures are of any greater importance than any other text or tables, and the Risk Management disclosure should be read in its entirely.
The disclosures in the Risk Management section of this document should be considered carefully together with other information in this MD&A and in the 2023 AIF, our Consolidated Financial Statements and other reports and materials that we file with securities regulators.
In this section, segregated funds include segregated fund guarantees, variable annuities and investment products, and includes Run-off reinsurance in U.S. In-force Management.

Our Risk Framework groups all risks into six major risk categories: market, insurance, credit, business and strategic, operational and liquidity risks.

i. Market Risk
Risk Description
We are exposed to market risk, which is defined as the risk that the value or future cash flows of insurance and investment contract liabilities or financial assets will fluctuate because of changes or volatility in market prices. Market risk includes equity, interest rate and spread, real estate, foreign currency, and inflation risks.

Market Risk Management Governance and Control
We employ a wide range of market risk management practices and controls as outlined below:
•Market risk governance practices are in place, including independent monitoring and review and reporting to senior management and the Risk Committee.
58 December 31, 2023 Sun Life Financial Inc.      MANAGEMENT'S DISCUSSION & ANALYSIS         


•Income and regulatory capital sensitivities are monitored, managed, and reported against pre-established risk appetite limits for equity, interest rate, credit spread, real estate and foreign currency risks.
•Comprehensive asset-liability management and hedging policies, programs and practices are in place.
•Regulatory solvency requirements include risk-based capital requirements and are monitored regularly.
•Product Design and Pricing Policy requires a detailed risk assessment and pricing provisions for material risks.
•Stress-testing techniques, such as FCT, are used to measure the effects of large and sustained adverse market movements.
•Insurance contract liabilities are established in accordance with Canadian actuarial standards of practice and International Financial Reporting Standards.
•Internal capital targets are established at an enterprise level to cover all risks and are above minimum regulatory and supervisory levels. Actual capital levels are monitored to ensure they exceed internal targets.

Specific market risks and our risk management strategies are discussed below in further detail.

Equity Risk
Equity risk is the potential for financial loss arising from declines or volatility in equity market prices. We are exposed to equity risk from a number of sources.

We generate revenue in our asset management businesses and from certain insurance and annuity contracts where fees are levied on account balances that are affected directly by equity market levels. Accordingly, we have further exposure to equity risk as adverse fluctuations in the market value of such assets will result in corresponding adverse impacts on revenue, income, and the contractual service margin. In addition, declining and volatile equity markets may have a negative impact on sales and redemptions (surrenders) in these businesses, and this may result in further adverse impacts on net income, the contractual service margin, and capital.

A portion of our exposure to equity risk arises in connection with benefit guarantees on segregated fund products, some participating insurance contracts, some adjustable insurance contracts, and some universal life contracts. These benefit guarantees may be triggered upon death, maturity, withdrawal or annuitization. The cost of providing these guarantees is uncertain and depends upon a number of factors, including general capital market conditions, our hedging strategies, policyholder behaviour and mortality experience, each of which may result in negative impacts on net income, the contractual service margin, and capital.

We also have direct exposure to equity markets from the investments supporting other general account liabilities, surplus, and employee benefit plans. These exposures fall within our risk-taking philosophy and appetite, and are therefore generally not hedged.

Interest Rate and Spread Risk
Interest rate and spread risk includes the potential for financial loss arising from changes in the value of insurance and investment contract liabilities and financial assets due to changes or volatility in interest rates or spreads. In practice, when asset cash flows and the policy obligations they support are not matched, this may result in the need to either sell assets to meet policy payments and expenses or reinvest excess asset cash flows in unfavourable interest rate or credit spread environments. This risk is managed in our asset-liability management program. Details of the asset-liability management program are discussed under the heading "Market Risk Management Governance and Control" in section K - Risk Management in this document.

Our primary exposure to interest rate and spread risk arises from insurance and investment contracts that contain guarantees in the form of minimum crediting rates, maximum premium rates, settlement options, guaranteed annuitization options and minimum benefits. If investment returns fall below guaranteed levels, we may be required to increase liabilities or capital in respect of these contracts. The guarantees attached to these products may be applicable to both past premiums collected and future premiums not yet received. Segregated fund contracts provide benefit guarantees that are linked to underlying fund performance and may be triggered upon death, maturity, withdrawal or annuitization. Exposure to guarantees is managed within our risk appetite limits through our asset-liability management program, which may include the use of hedging strategies utilizing interest rate derivatives such as interest rate floors, swaps, futures and swaptions. The impact of these guarantees on net income, contractual service margin, and capital are included in the disclosed market risk sensitivities.

Significant changes or volatility in interest rates or spreads could have a negative impact on sales of certain insurance and annuity products, and adversely impact the expected pattern of redemptions (surrenders) on existing policies. Increases in interest rates or widening credit spreads may increase the risk that policyholders will surrender their contracts, potentially forcing us to liquidate assets at a loss. While we have established hedging programs in place and our insurance and annuity products often contain surrender mitigation features, these may not be sufficient to fully offset the adverse impact of changes in interest rates or spreads. Declines in interest rates or narrowing spreads can result in compression of the net spread between interest earned on investments and interest credited to policyholders. Declines in interest rates or narrowing spreads can also result in increased asset calls, mortgage prepayments, and net reinvestment of positive cash flows at lower yields, and therefore adversely impact our profitability and financial position. Negative interest rates may additionally result in losses on our cash and short-term deposits and low or negative returns on our fixed income assets impacting our profitability.
We also have direct exposure to interest rates and spreads from investments supporting other general account liabilities, surplus and employee benefit plans. Higher interest rates or wider spreads will reduce the value of our existing assets. Conversely, lower interest rates or a narrowing of spreads will result in reduced investment income on new fixed income asset purchases. These exposures fall within our risk-taking philosophy and appetite and are therefore generally not hedged.


A sustained low interest rate environment may additionally adversely impact our net income, CSM, capital, and our ability to implement our business strategy and plans. This may be realized through lower sales, less profitable new business, changes in the pattern of redemptions on existing policies, among other impacts.

                 MANAGEMENT'S DISCUSSION & ANALYSIS Sun Life Financial Inc. December 31, 2023 59


Real Estate Risk
Real estate risk is the potential for financial loss arising from fluctuations in the value of, or future cash flows from, our investments in real estate. We are exposed to real estate risk and may experience financial losses resulting from the direct ownership of real estate investments or indirectly through fixed income investments secured by real estate property, leasehold interests, ground rents, and purchase and leaseback transactions. Real estate price risk may arise from external market conditions, inadequate property analysis, inadequate insurance coverage, inappropriate real estate appraisals, or from environmental risk exposures. We hold real estate investments that support general account liabilities and surplus, and fluctuations in value will affect our net income, CSM, and capital. A material and sustained increase in interest rates may lead to deterioration in real estate values.

Foreign Currency Risk
Foreign currency risk is the result of mismatches in the currency of our assets and liabilities (inclusive of capital), and cash flows. This risk may arise from a variety of sources such as foreign currency transactions and services, foreign currency hedging, investments denominated in foreign currencies, investments in foreign subsidiaries and net income from foreign operations. Changes or volatility in foreign exchange rates, including a change to currencies that are fixed in value to another currency, could adversely affect our net income, contractual service margin and capital.

As an international provider of financial services, we operate in a number of countries, with revenues and expenses denominated in several local currencies. In each country in which we operate, we generally maintain the currency profile of assets to match the currency of liabilities and required capital. This approach provides an operational hedge against disruptions in local operations caused by currency fluctuations. Foreign currency derivative contracts such as currency swaps and forwards are used as a risk management tool to manage the currency exposure in accordance with our Asset Liability Management Policy. As at December 31, 2023 and December 31, 2022, the Company did not have a material foreign currency risk exposure.

Changes in exchange rates can affect our net income and surplus when financial results in functional currencies are translated into Canadian dollars. Net income earned outside of Canada is generally not currency hedged and a weakening in the local currency of our foreign operations relative to the Canadian dollar can have a negative impact on our net income reported in Canadian currency. A strengthening in the local currency of our foreign operations relative to the Canadian dollar would have the opposite effect. Regulatory capital ratios could also be impacted by changes in exchange rates.

Inflation Risk
Inflation risk is the potential for financial loss arising from changes in inflation rates. This risk results from insurance contract liabilities that are linked to market measures of inflation such as the Consumer Price Index. The primary sources for this risk exposure are from certain group and retail annuity contracts and group long term disability contracts. In these contracts, the annuity and disability benefit payments may be linked to an indexing formula containing an inflation price index. Benefit payments linked to inflation indices may also include various caps, floors and averaging mechanisms that vary across product designs.

Exposure to inflation risk is managed within our asset-liability management program, primarily by investing in inflation linked assets to match liability exposures.

Market Risk Sensitivities
We use a variety of methods and measures to manage and quantify our market risk exposures. These include duration and key rate duration management, convexity measures, cash flow gap analysis, scenario testing, and sensitivity testing of earnings and regulatory capital ratios.

The measurement of liabilities and assets are affected by the level of equity market performance, interest rates, credit and swap spreads and other market risk variables. The following sections set out the estimated immediate impact on, or sensitivity of, our net income(1), contractual service margin, OCI and SLF Inc.'s LICAT ratio to certain instantaneous changes in market variables as at December 31, 2023 and December 31, 2022(2).


















(1)Net income in section K - Risk Management in this document refers to common shareholders' net income.
(2)Effective January 1, 2023, we adopted IFRS 17 and IFRS 9, and certain financial assets were reclassified between measurement categories as permitted. December 31, 2022 amounts provided in the sensitivities in section K - Risk Management of this document have been adjusted to reflect these January 1, 2023 reclassifications. See Note 2 of the 2023 Annual Consolidated Financial Statements for further details on the reclassifications.
60 December 31, 2023 Sun Life Financial Inc.


The estimated sensitivities in the tables below reflect the impact of market movements on insurance contracts and investment contracts, assets backing insurance contracts, assets backing investment contracts, assets backing the surplus segment, and seed investments in our asset management subsidiaries.

Net income sensitivities to equity and real estate market movements are driven primarily by changes in the value of investments backing general account liabilities and surplus. Net income sensitivities to interest rates and spreads are driven by the net impact on liabilities and the assets backing them. Lower interest rates or a narrowing of spreads will result in increased liabilities for insurance contracts, offset by increased values of the assets backing general account liabilities. Higher interest rates or a widening of spreads will result in decreased liabilities for insurance contracts, offset by decreased values of the assets backing general account liabilities. Further detail on the impact of changes or volatility in market prices on assets and liabilities is provided under the headings "Equity Risk", "Interest Rate and Spread Risk", and "Real Estate Risk" above.

OCI sensitivities are impacted by changes in the market value of assets classified as FVOCI. The market value of FVOCI fixed income assets, which are held primarily in our surplus and investment contract segments, increases with lower interest rates or a narrowing of spreads, and decreases with higher interest rates or a widening of spreads.

As these market risk sensitivities reflect an instantaneous impact on net income, CSM, OCI and SLF Inc.'s LICAT ratio, they do not include impacts over time such as the effect on fee income in our asset management businesses.

Refer to Additional Cautionary Language and Key Assumptions Related to Sensitivities in this section for important additional information regarding these estimates.

The above sensitivities were determined using a 50 basis point change in interest rates and a 10% and 25% changes in our equity markets because we believe that these market shocks were reasonably possible as at December 31, 2023. Significant changes in market variables may result in other than proportionate impacts on our sensitivities.

Potential Impact of Change in Ultimate Risk-Free Rate
Interest rate sensitivities do not include any impact from changes to the ultimate risk-free rate. Our estimated sensitivity to a 10 basis point decrease in the ultimate risk-free rate assumed in our insurance contract liabilities is a decrease in reported net income of approximately $50 million after-tax, and a decrease in CSM of approximately $25 million.

Credit Spread and Swap Sensitivities
Credit spread sensitivities reflect the impact of changes in credit spreads on our asset and liability values (including provincial government bonds, corporate bonds, and other fixed income assets). Swap spread sensitivities reflect the impact of changes in swap spreads on swap-based derivative positions and liability values.
The following tables set out the estimated immediate impact on, or sensitivity of, our net income, CSM, OCI and SLF Inc.'s LICAT ratio to certain instantaneous changes in credit spreads and our net income, CSM, and OCI to certain changes in swap spreads as at December 31, 2023 and December 31, 2022(1).

LICAT Interest Rate Scenario Switch
The LICAT interest rate risk is assessed under four different interest rate scenarios, and the scenario leading to the highest capital requirement is chosen as the worst scenario for each geographic region as defined by the LICAT guideline. Changes and interaction between the level and term movements in interest rates and credit spreads can shift the interest rate scenario applied in the LICAT calculation causing a discontinuity where capital requirements change materially. In 2020, OSFI updated the LICAT guideline for interest rate risk requirements for participating businesses to be smoothed over six quarters. As a result, the actual impact to the LICAT ratio from participating businesses in any quarter will reflect the scenarios from current quarter as well as the prior five quarters and switching between the scenarios would have the effect of offsetting the previous impacts over time. It should be noted that switching of the scenario can also change the direction of our sensitivities.

In Q4'23, SLF Inc. experienced a scenario switch, resulting in no change in the LICAT ratio. For SLF Inc., assuming no further scenario switches, the remaining impact of one percentage point is expected to decrease the LICAT ratio over the next five quarters.

In Q4'23, Sun Life Assurance experienced a scenario switch, resulting in one-and-a-half percentage change to the LICAT ratio. For Sun Life Assurance, assuming no further scenario switches, the remaining impact of four-and-a-half percentage points is expected to decrease the LICAT ratio over the next five quarters.

Market Risk Management Strategies
Market risk is managed at all stages during the product life cycle including product design and development, ongoing review and positioning of our suite of products, and ongoing asset-liability management and hedge re-balancing. Our market risk management strategies are developed based on policies and operating guidelines at the enterprise level, business segment level and product level. Liabilities having a similar risk profile are grouped together and a customized investment and hedging strategy is developed and implemented to optimize return within our risk appetite limits.

We have implemented asset-liability management and hedging programs involving regular monitoring and adjustment of market risk exposures using assets, derivative instruments and repurchase agreements to maintain market risk exposures within our risk appetite. The general availability and cost of these hedging instruments may be adversely impacted by a number of factors including changes in interest rates, increased volatility in capital markets, and changes in the general market and regulatory environment within which these hedging programs operate. In particular, regulations for derivatives could impose additional costs and could affect our hedging strategy. In addition, these programs may themselves expose us to other risks.
In general, market risk exposure is mitigated by the assets supporting our products. This includes holdings of fixed income assets such as bonds and mortgages. Derivative instruments may supplement these assets to reduce the risk from cash flow mismatches and mitigate the market risk associated with liability features and optionality.

                 MANAGEMENT'S DISCUSSION & ANALYSIS Sun Life Financial Inc. December 31, 2023 63


General Account Insurance and Annuity Products
Most of our expected net income sensitivity to changes in interest rates and equity markets is derived from our general account insurance and annuity products. We have implemented market risk management strategies to mitigate a portion of the market risk related to our general account insurance and annuity products.

Individual insurance products include universal life and other long-term life and health insurance products. Major sources of market risk exposure for individual insurance products include the reinvestment risk related to future premiums on regular premium policies, asset reinvestment risk on both regular premium and single premium policies and the guaranteed cost of insurance. Interest rate risk for individual insurance products is typically managed on a duration basis, within tolerance ranges set out in the applicable investment policy or guidelines. Targets and limits are established so that the level of residual exposure is commensurate with our risk appetite. Exposures are monitored frequently, and assets are re-balanced as necessary to maintain compliance within prescribed tolerances using a combination of assets and derivative instruments. A portion of the longer-term cash flows are backed with equities and real estate.

For participating insurance products and other insurance products with adjustable features, the investment strategy objective is to provide a total rate of return given a constant risk profile over the long term.

Fixed annuity products generally provide the policyholder with a guaranteed investment return or crediting rate. Interest rate risk for these products is typically managed on a duration basis, within tolerance ranges set out in the applicable investment guidelines. Targets and limits are established so that the level of residual exposure is commensurate with our risk appetite. Exposures are monitored frequently, and assets are re-balanced as necessary to maintain compliance within prescribed tolerances using a combination of fixed income assets and derivative instruments.

Certain insurance and annuity products contain minimum interest rate guarantees. Market risk management strategies are implemented to limit potential financial loss due to reductions in asset earned rates relative to contract guarantees. These typically involve the use of hedging strategies utilizing interest rate derivatives such as interest rate floors, swaps and swaptions.

Certain insurance and annuity products contain features which allow the policyholders to surrender their policy at book value. Market risk management strategies are implemented to limit the potential financial loss due to changes in interest rate levels and policyholder behaviour. These typically involve the use of dynamic hedging strategies and the purchase of interest rate swaptions.

Certain products have guaranteed minimum annuitization rates. Market risk management strategies are implemented to limit the potential financial loss and typically involve the use of fixed income assets, interest rate swaps, and swaptions.

Segregated Funds Products
Certain segregated fund products provide benefit guarantees, which are linked to underlying fund performance and may be triggered upon death, maturity, withdrawal or annuitization. The cost of providing these guarantees is uncertain and depends upon a number of factors including general capital market conditions, our hedging activities, policyholder behaviour and mortality experience, each of which may result in negative impacts on net income, the contractual service margin and capital.

Our hedging programs use derivative instruments and fixed income assets to mitigate the interest rate, equity market, and foreign currency exposure of our segregated fund contracts. As at December 31, 2023, over 90% of our segregated fund contracts, as measured by fund values, were included in a hedging program. While a large percentage of contracts are included in the hedging program, not all of our market risk exposure related to these contracts is hedged. For those segregated fund contracts included in the hedging program, we generally hedge the value of expected future net claims costs and associated risk adjustments for non-financial risk.

Our hedging strategy is applied both at the line of business or product level and at the total company level using a combination of hedging techniques such as re-balancing of short-dated interest rate and equity derivative contracts and longer-dated put options. We actively monitor our overall market exposure and may implement tactical hedge overlay strategies in order to align sensitivities with risk management objectives.

The impact of segregated fund guarantees and associated hedging programs on net income, contractual service margin and capital are included in the disclosed market risk sensitivities.

64 December 31, 2023 Sun Life Financial Inc. MANAGEMENT'S DISCUSSION & ANALYSIS The primary uses of derivatives are set out in the table below as at December 31, 2023.


Market Risk Management Applications for Derivative Usage
Products/Application Uses of Derivative Derivatives Used
General asset-liability management - interest rate risk exposure for most insurance and annuity products To manage the sensitivity of the duration gap between assets and liabilities to interest rate changes Interest rate swaps, swaptions, floors and bond futures
Guarantees on insurance and annuity contracts - minimum interest rate guarantees, guaranteed surrender values and guaranteed annuitization options To limit potential financial losses from significant reductions in asset earned rates relative to contract guarantees Interest rate swaps, swaptions, floors and bond futures
Segregated fund guarantees To manage the exposure of product guarantees sensitive to movement in equity market and interest rate levels and currency fluctuations Put options, call options, futures and swaps on equity indices, interest rate swaps, bond futures, and foreign exchange forwards
Currency exposure in relation to asset-liability management To reduce the sensitivity to currency fluctuations by matching the value and cash flows of specific assets denominated in one currency with the value and cash flows of the corresponding liabilities denominated in another currency Currency swaps and forwards
Credit exposure To replicate credit exposures and enhance investment returns Credit default swaps

Additional Cautionary Language and Key Assumptions Related to Sensitivities
Our market risk sensitivities are measures of our estimated change in net income, OCI, CSM and LICAT ratio for changes in market risk variables described above, based on market risk variables and business in force as at the reporting date. These sensitivities are calculated independently for each risk factor, generally assuming that all other risk variables stay constant. The sensitivities do not take into account indirect effects such as potential impacts on goodwill impairment or valuation allowances on deferred tax assets.
We have provided measures of our net income sensitivity to instantaneous changes in equity markets, interest rates, credit spreads, swap spreads, real estate price levels, and capital sensitivities to changes in equity price levels, interest rates and credit spreads. The LICAT ratio and CSM sensitivities are non-IFRS financial measures, and for additional information, see section M - Non-IFRS Financial Measures in this document. The cautionary language which appears in this section is applicable to all net income, CSM, OCI and LICAT ratio sensitivities.

Actual results can differ materially from these estimates for a variety of reasons, including differences in the pattern or distribution of the market shocks, the interaction between these risk factors, model error, or changes in other assumptions such as business mix, effective tax rates, policyholder behaviour, currency exchange rates and other market variables relative to those underlying the calculation of these sensitivities. The extent to which actual results may differ from the indicative ranges will generally increase with larger movements in risk variables. Our sensitivities as at December 31, 2022(1) have been included for comparative purposes only.

Sensitivities to interest rates and credit spreads assume a parallel shift in assumed interest rates across the entire yield curve or a parallel shift in the indicated spreads across the entire term structure, with no change to the ultimate risk-free rate or ultimate liquidity premium. Realized sensitivities may be significantly differently from those illustrated based on factors such as different terms to maturity, geographies, asset classes and derivative types, and ratings.

The sensitivities reflect the composition of our assets and liabilities as at December 31, 2023 and December 31, 2022(1), respectively. Changes in these positions due to new sales or maturities, asset purchases/sales, or other management actions could result in material changes to these reported sensitivities. In particular, these sensitivities reflect the expected impact of hedging activities based on the hedging programs in place as at the respective calculation dates. The actual impact of hedging activity can differ materially from that assumed in the estimated sensitivities due to ongoing hedge re-balancing activities, changes in the scale or scope of hedging activities, changes in the cost or general availability of hedging instruments, basis risk (i.e., the risk that hedges do not exactly replicate the underlying portfolio experience), model risk, and other operational risks in the ongoing management of the hedge programs or the potential failure of hedge counterparties to perform in accordance with expectations.
Our hedging programs may themselves expose us to other risks, including basis risk, volatility risk, and increased levels of derivative counterparty credit risk, liquidity risk, model risk and other operational risks. These factors may adversely impact the net effectiveness, costs, and financial viability of maintaining these hedging programs and therefore adversely impact our profitability and financial position. While our hedging programs are intended to mitigate these effects (e.g., hedge counterparty credit risk is managed by maintaining broad diversification, dealing primarily with highly-rated counterparties, and transacting through over-the-counter ("OTC") contracts cleared through central clearing houses, exchange-traded contracts or bilateral OTC contracts negotiated directly between counterparties that include credit support annexes), residual risk, potential reported earnings and capital volatility remain.




(1)Effective January 1, 2023, we adopted IFRS 17 and IFRS 9, and certain financial assets were reclassified between measurement categories as permitted. December 31, 2022 amounts provided in the sensitivities in section K - Risk Management of this document have been adjusted to reflect these January 1, 2023 reclassifications. See Note 2 of the 2023 Annual Consolidated Financial Statements for further details on the reclassifications.
                 MANAGEMENT'S DISCUSSION & ANALYSIS Sun Life Financial Inc. December 31, 2023 65


The sensitivities are based on methods and assumptions in effect as at December 31, 2023 and December 31, 2022(1), as applicable. Changes in the regulatory environment, assumptions or methods used to measure assets and liabilities after those dates could result in material changes to the estimated sensitivities. Changes in market risk variables in excess of the changes illustrated may result in other than proportionate impacts.
The sensitivities reflect the CSM as at December 31, 2023 and December 31, 2022(1). For insurance contracts measured using the VFA, where the change in the effect of the time value of money and financial risk not arising from the underlying items adjusts the CSM, changes in the CSM balance will affect the sensitivity of income to changes in market risk variables.

Our LICAT sensitivities may be non-linear and can change due to the interrelationship between market rates and spreads, actuarial assumptions and our LICAT calculations.

For the reasons outlined above, our sensitivities should only be viewed as indicative estimates of the underlying sensitivities of each factor under these specialized assumptions, and should not be viewed as predictors of our future income, OCI, CSM or capital. Given the nature of these calculations, we cannot provide assurance that actual impacts will be consistent with the estimates provided.
Information related to market risk sensitivities should be read in conjunction with the information contained in section N - Accounting and Control Matters - 1 - Critical Accounting Policies and Estimates in this document. Additional information on market risk can be found in Note 2 and Note 6 of the 2023 Annual Consolidated Financial Statements and the Risk Factors section in the 2023 AIF.

ii. Insurance Risk
Risk Description
Insurance risk is the uncertainty of product performance due to actual experience emerging differently than expected in the areas of mortality, morbidity and longevity. In addition, policyholder behaviour, product design and pricing, expense and reinsurance risks impact multiple risk categories, including insurance risk.

Insurance Risk Management Governance and Control
We employ a wide range of insurance risk management practices and controls, as outlined below:
•Insurance risk governance practices are in place, including independent monitoring and review and reporting to senior management and the Risk Committee.
•Income and regulatory capital sensitivities are monitored, managed and reported against pre-established risk appetite limits for policyholder behaviour, mortality, morbidity and longevity risks.
•Comprehensive Insurance Risk Policy, guidelines and practices are in place.
•The global underwriting manual aligns underwriting practices with our corporate risk management standards and ensures a consistent approach in insurance underwriting.
•Board-approved maximum retention limits are in place. Amounts issued in excess of these limits are reinsured.
•Detailed procedures, including criteria for approval of risks and for claims adjudication are established and monitored for each business segment.
•Underwriting and risk selection standards and procedures are established and overseen by the corporate underwriting and claims risk management function.
•Diversification and risk pooling is managed by aggregation of exposures across product lines, geography and distribution channels.
•We use reinsurance to limit losses, minimize exposure to significant risks and to provide additional capacity for growth.
•The Insurance Risk Policy and Investment & Credit Risk Policy establish acceptance criteria and protocols to monitor the level of reinsurance ceded to any single reinsurer or group of reinsurers.
•Reinsurance counterparty risk is monitored, including annual reporting of reinsurance exposure to the Risk Committee.
•Various limits, restrictions and fee structures are introduced into plan designs in order to establish a more homogeneous policy risk profile and limit potential for anti-selection.
•Regulatory solvency requirements include risk-based capital requirements and are monitored regularly.
•The Product Design and Pricing Policy requires detailed risk assessment and pricing provision for material risks.
•Company specific and industry level experience studies and drivers of earnings analysis are monitored and factored into valuation, renewal and new business pricing processes.
•Stress-testing techniques, such as FCT, are used to measure the effects of large and sustained adverse movements in insurance risk factors.
•Internal capital targets are established at an enterprise level to cover all risks and are above minimum regulatory and supervisory levels.

The concentration for insurance risks is monitored geographically and its adverse effect is mitigated through a diversified product portfolio, product design, underwriting standards and practices, utilizing reinsurance as well as the Company's global operation. Specific to the reinsurance risk, the concentration is measured by aggregating the exposure to each reinsurance counterparty across all Business Groups to ensure it does not exceed a predefined risk level.

Specific insurance risks and our risk management strategies are discussed below in further detail.

66 December 31, 2023 Sun Life Financial Inc.      MANAGEMENT'S DISCUSSION & ANALYSIS         


Policyholder Behaviour Risk
We can incur losses due to adverse policyholder behaviour relative to the assumptions used in the pricing and valuation of products regarding lapse of policies or exercise of other embedded policy options.

Uncertainty in policyholder behaviour can arise from several sources including unexpected events in the policyholder's life circumstances, the general level of economic activity (whether higher or lower than expected), changes in the financial and capital markets, changes in pricing and availability of current products, the introduction of new products, changes in underwriting technology and standards, as well as changes in our financial strength or reputation. Uncertainty in future cash flows affected by policyholder behaviour can be further exacerbated by unexpected behaviour during times of economic turbulence or at key option exercise points in the life of an insurance contract.

Various types of provisions are built into many of our products to reduce the impact of uncertain policyholder behaviour. These provisions include:
•Surrender charges that adjust the payout to the policyholder by taking into account prevailing market conditions.
•Limits on the amount that policyholders can surrender or borrow.
•Restrictions on the timing of policyholders' ability to exercise certain options.
•Restrictions on both the types of funds policyholders can select and the frequency with which they can change funds.
•Policyholder behaviour risk is also mitigated through reinsurance on some insurance contracts.

Internal experience studies are used to monitor, review and update policyholder behaviour assumptions as needed, which could result in updates to policy liabilities.

Mortality and Morbidity Risk
Mortality and morbidity risk is the risk that future experience could be unfavourable relative to the assumptions used in the pricing and valuation of products. Mortality and morbidity risk can arise in the normal course of business through random fluctuation in realized experience, through catastrophes, as a result of a pandemic, or in association with other risk factors such as product development and pricing risk. Adverse mortality and morbidity experience could also occur through systemic anti-selection, which could arise due to poor plan design, or underwriting process failure or the development of investor-owned and secondary markets for life insurance policies.

External factors could adversely affect our life insurance, health insurance, critical illness, disability, long-term care insurance and annuity businesses. Morbidity experience could be unfavourably impacted by external events, such as pandemics, increases in disability claims during economic slowdowns and increases in high medical treatment costs and growth in utilization of specialty drugs. This introduces the potential for adverse financial results.

Detailed uniform underwriting procedures have been established to determine the insurability of applicants and to manage exposure to large claims. These underwriting requirements are regularly scrutinized against industry guidelines and oversight is provided through a corporate underwriting and claim management function.

The Insurance Risk Policy, which is approved by the Risk Committee, sets out limits on the maximum amount of insurance risk per life that may be retained. Amounts in excess of the Board-approved maximum retention limits are reinsured. On a single life or joint-first-to-die basis our retention limit is $40 in Canada and US$40 outside of Canada. For survivorship life insurance, our maximum global retention limit is $50 in Canada and US$50 outside of Canada. In certain markets and jurisdictions, retention levels below the maximum are applied. Reinsurance is utilized for numerous products in most business segments, and placement is done on an automatic basis for defined insurance portfolios and on a facultative basis for individual risks with certain characteristics.

Concentration risk exposure is monitored on group policies in a single location. We do not have a high degree of concentration risk to single individuals or groups due to our well-diversified geographic and business mix. The largest portion of mortality risk within the Company is in North America. Individual and group insurance policies are underwritten prior to initial issue and renewals, based on risk selection, plan design, and rating techniques.

Retention limits per life vary by geographic region and amounts in excess of limits are reinsured to ensure there is no exposure to unreasonable concentration of risk.

Longevity Risk
Longevity risk is the potential for losses arising from adverse changes in rates of mortality improvement relative to the assumptions used in the pricing and valuation of products. This risk can manifest itself slowly over time as socioeconomic conditions improve and medical advances continue. It could also manifest itself more quickly, for example, due to medical breakthroughs that significantly extend life expectancy. Longevity risk affects contracts where benefits or costs are based upon the likelihood of survival and higher than expected improvements in insured life expectancy could therefore increase the ultimate cost of these benefits (for example, annuities, pensions, pure endowments, some segregated funds, and specific types of health contracts).

To improve management of longevity risk, we monitor research in the fields that could result in a change in expected mortality improvement. Stress-testing techniques are used to measure and monitor the impact of extreme mortality improvement on the aggregate portfolio of insurance and annuity products.

Product Design and Pricing Risk
Product design and pricing risk is the risk a product does not perform as expected, causing adverse financial consequences. This risk may arise from deviations in realized experience versus assumptions used in the pricing of products. Risk factors include uncertainty concerning future investment yields, policyholder behaviour, mortality and morbidity experience, sales levels, mix of business, expenses and taxes. Although some of our products permit us to increase premiums or adjust other charges and credits during the life of the policy or contract, the terms of these policies or contracts may not allow for sufficient adjustments to maintain expected profitability. This could have an adverse effect on our profitability and capital position.
                 MANAGEMENT'S DISCUSSION & ANALYSIS Sun Life Financial Inc. December 31, 2023 67


Our Product Design and Pricing Policy, approved by the Risk Committee, establishes the framework governing our product design and pricing practices and is designed to align our product offerings with our strategic objectives and risk-taking philosophy. Consistent with this policy, product development, design and pricing processes have been implemented throughout the Company. New products follow a stage-gate process with defined management approvals based on the significance of the initiative. Each initiative is subject to a risk assessment process to identify key risks and risk mitigation requirements and is reviewed by multiple stakeholders. Additional governance and control procedures are listed below:
•Pricing models, methods, and assumptions are subject to periodic internal peer reviews.
•Experience studies, drivers of earnings analysis, and product dashboards are used to monitor actual experience against those assumed in pricing and valuation.
•On experience rated, participating, and adjustable products, emerging experience is reflected through changes in policyholder dividend scales as well as other policy adjustment mechanisms such as premium and benefit levels.
•Limits and restrictions may be introduced into the design of products to mitigate adverse policyholder behaviour or apply upper thresholds on certain benefits.

Expense Risk
Expense risk is the risk that future expenses are higher than the assumptions used in the pricing and valuation of products. This risk can arise from general economic conditions, unexpected increases in inflation, slower than anticipated growth, or reduction in productivity leading to increases in unit expenses. Expense risk occurs in products where we cannot or will not pass increased costs onto the policyholder and will manifest itself in the form of a liability increase or a reduction in expected future profits.

We closely monitor expenses through an annual budgeting process and ongoing monitoring of any expense gaps between unit expenses assumed in pricing and actual expenses.

Reinsurance Risk
We purchase reinsurance for certain risks underwritten by our various insurance businesses. Reinsurance risk is the risk of financial loss due to adverse developments in reinsurance markets (for example, discontinuance or diminution of reinsurance capacity, or an increase in the cost of reinsurance), insolvency of a reinsurer or inadequate reinsurance coverage. While reinsurance arrangements provide for the recovery of claims arising from the liabilities ceded, we retain primary responsibility to the policyholders.

Rates for our in-force reinsurance treaties can be either guaranteed or adjustable for the life of the ceded policy. Changes in reinsurance market conditions, including actions taken by reinsurers to increase rates on existing and new coverage and our ability to obtain appropriate reinsurance, may adversely impact the availability or cost of maintaining existing or securing new reinsurance capacity, with adverse impacts on our business strategies, profitability and financial position. There is a possibility of rate increases or renegotiation of some of the legacy reinsurance contracts by our reinsurers, as the global reinsurance industry continues to review and optimize their business models. In addition, changes to the regulatory treatment of reinsurance arrangements could have an adverse impact on our capital position.

We have an Insurance Risk Policy approved by the Risk Committee and an Investment & Credit Risk Policy approved by the Governance, Investment & Sustainability Committee, which set acceptance criteria and processes to monitor and manage the level of reinsurance ceded to any single reinsurer. These policies are regularly reviewed and approved by the relevant Board Committee to ensure the alignment with our risk appetite levels and reinsurance risk guidelines.

The policies set the acceptance criteria which verify if a reinsurer qualifies as a suitable reinsurance counterparty, having the capability, expertise, governance practices and financial capacity to assume the risks being considered. In addition, a periodic due diligence is performed on the existing reinsurance counterparties, including an internal credit assessment for reinsurance counterparties with whom we have material exposure.

The exposure to each reinsurance counterparty is monitored closely to ensure that no single reinsurance counterparty represents an undue level of credit risk and does not exceed the predefined limits. In order to diversify our reinsurance risk, there is generally more than one reinsurance counterparty supporting a reinsurance pool. A summary of the reinsurance counterparty credit risk exposures is reported annually to the Risk Committee.

To further increase the reinsurance risk control, our reinsurance agreements include provisions to allow actions to be taken, such as recapture of ceded risk (at a potential cost to the Company), in the event that the reinsurance counterparty loses its legal ability to carry on business through insolvency or regulatory action.

In case of unfavourable developments in the reinsurance markets, we also have an option to discontinue or implement changes to the new sales of our products to better manage the associated risks.

Additional information on insurance risk can be found in Note 7 of our 2023 Annual Consolidated Financial Statements and in the Risk Factors section in the AIF.

iii. Credit Risk
Risk Description
Credit risk is the possibility of loss from amounts owed by our borrowers or financial counterparties. We are subject to credit risk in connection with issuers of securities held in our investment portfolio, debtors, structured securities, reinsurers, counterparties (including derivative, repurchase agreement and securities lending counterparties), other financial institutions and other entities. Losses may occur when a counterparty fails to make timely payments pursuant to the terms of the underlying contractual arrangement or when the counterparty's credit rating or risk profile otherwise deteriorates. Credit risk can also arise in connection with deterioration in the value of, or ability to realize, any underlying security that may be used as collateral for the debt obligation. Credit risk can occur as a result of broad economic conditions, challenges within specific sectors of the economy, or from issues affecting individual companies. Events that result in
68 December 31, 2023 Sun Life Financial Inc.


MANAGEMENT'S DISCUSSION & ANALYSIS defaults, impairments or downgrades of the securities in our investment portfolio would cause the Company to record realized or unrealized losses and may cause an increase in our provisions for asset default, adversely impacting earnings.

Credit Risk Management Governance and Control
We employ a wide range of credit risk management practices and controls, as outlined below:
•Credit risk governance practices are in place, including independent monitoring and review and reporting to senior management and the Risk Committee.
•Risk appetite limits have been established for credit risk.
•Income and regulatory capital sensitivities are monitored, managed and reported against pre-established risk limits.
•Comprehensive Investment and Credit Risk Management Policy, guidelines and practices are in place.
•Specific investment diversification requirements are in place, such as defined investment limits for asset class, geography, and industry.
•Risk-based credit portfolio, counterparty, and sector exposure limits have been established.
•Mandatory use of credit quality ratings for portfolio investments has been established and is reviewed regularly. These internal rating decisions for new fixed income investments and ongoing review of existing rating decisions are independently adjudicated by Corporate Risk Management.
•Comprehensive due diligence processes and ongoing credit analyses are conducted.
•Regulatory solvency requirements include risk-based capital requirements and are monitored regularly.
•Comprehensive compliance monitoring practices and procedures including reporting against pre-established investment limits are in place.
•Reinsurance exposures are monitored to ensure that no single reinsurer represents an undue level of credit risk.
•Stress-testing techniques, such as FCT, are used to measure the effects of large and sustained adverse credit developments.
•Insurance contract liabilities are established in accordance with Canadian actuarial standards of practice.
•Internal capital targets are established at an enterprise level to cover all risks and are above minimum regulatory and supervisory levels. Actual capital levels are monitored to ensure they exceed internal targets.

Our core principles of credit risk management include asset diversification, fundamental research and analysis of cash flows, proactive and continuous risk monitoring, active management and relative value assessment, all with the objective of optimizing risk-adjusted returns, with due consideration for the impacts of capital and taxation.

We rate fixed income investments primarily through the use of internally developed scorecards which combine an estimated probability of default and loss given default to determine an expected loss and credit risk rating. This rating is expressed using a 22-point scale that is generally consistent with those used by external rating agencies, and is based on detailed examination of the borrower's, or issuer's, credit quality and the characteristics of the specific instrument. The probability of default assessment is based on borrower-level or issuer-level analysis, which encompasses an assessment of industry risk, business strategy, competitiveness, strength of management and other financial information. The loss given default assessment is based on instrument-level analysis, which considers the impact of guarantees, covenants, liquidity and other structural features. These scorecards provide input to stochastic value-at-risk models and are used to stress test the portfolio, which provide insight into the distribution and characteristics of credit risk within our portfolios. In accordance with our policies and under normal circumstances, our ratings cannot be higher than the highest rating provided by certain Nationally Recognized Statistical Rating Organizations ("NRSROs"). Certain assets, including those in our sovereign debt and asset-backed securities portfolios, are assigned a rating based on ratings provided by NRSROs using a priority sequence order of Standard & Poor's, Moody's, Fitch and DBRS Limited.

Additional information on credit risk can be found in Note 6 of our 2023 Annual Consolidated Financial Statements and in the Risk Factors section in the AIF.

iv. Business and Strategic Risk
Risk Description
Business and strategic risk is the risk of loss from the inability to adequately identify, plan or implement an appropriate strategy to achieve strategic and business objectives or adapt to changes in Client behaviours, the external business, economic, geopolitical, regulatory or environmental and social landscape or when assumptions made in strategy are not realized as expected.

Business and Strategic Risk Management Governance and Control
We employ a wide range of business and strategic risk management practices and controls, as outlined below:
•Business and strategic risk governance practices are in place, including independent monitoring, review and reporting to Senior Management, the Board and the Board Committees.
•Business and strategic risk is managed through our strategic and business planning process and controls over the implementation of these plans. These plans are reviewed and discussed at the executive level and the key themes, issues and risks emerging are discussed by the Board and the Board Committees.
•Our Business and Strategic Plans are subject to approval by the Board, which also receives regular reviews of implementation progress against key Business Plan objectives.
•Comprehensive policies including the Risk Management Framework, Risk Appetite Policy, Product Design and Pricing Policy, Mergers and Acquisition Policy, Capital and Liquidity Management Framework and Capital Risk Policy are in place.
•Our corporate strategy and business objectives are established within the boundaries of the Risk Appetite Policy. Our business strategies and plans are designed to align with our risk appetite, our capital position and our financial performance objectives.
•Our risk appetite is periodically assessed, taking into consideration the economic and regulatory environments in which we operate.
•Merger, acquisition, strategic investments and divestiture transactions are governed by a Board-approved Merger and Acquisition Risk Management Policy and significant transactions require the approval of the Board.
•Stress-testing techniques, such as FCT, are used to measure the effects of large and sustained adverse scenarios.
•Key and emerging risks are identified, monitored and reported, including emerging regulatory changes that may have a material impact on our finances, operations or reputation.
                 MANAGEMENT'S DISCUSSION & ANALYSIS Sun Life Financial Inc. December 31, 2023 69


•Internal capital targets are established at an enterprise level to cover all risks and are above minimum regulatory and supervisory levels. Actual capital levels are monitored to ensure they exceed internal targets.

We regularly review and adapt our business strategies and plans to take account of changes in the external business, economic, geopolitical and regulatory environments in which we operate. Our business strategies and plans are designed to align with our risk appetite, our capital position and our financial performance objectives. We periodically reassess our risk appetite taking into consideration the economic, regulatory and competitive environment in which we operate.

Specific business and strategic risks are discussed below in further detail.

Geopolitical Risk
Geopolitical risk is the wide array of risks associated with conflict or tensions between states as well as events or trends with global or international dimensions that increase risks for the operations of companies. We operate in various geographies and our business and financial operations are susceptible to regional and global economic, geopolitical and regulatory changes. Geopolitical risk may lead to increased volatility in the global capital and energy markets, difficulty in conducting business in certain geographies, an increased threat of targeted cyber-attacks, and has the potential to introduce reputational risk.

Economic Risk
We may be affected by economic and capital markets conditions and economic shocks around the globe as a result of increasingly connected global markets. Factors such as changes in interest rates, foreign exchange rates, market volatility, housing prices, consumer spending, saving and debt, business investment and inflation around the globe can affect the business and economic environments in which we operate. In addition, adverse economic conditions often arise in conjunction with volatile and deteriorating capital markets conditions, which can have an adverse impact on Client behaviour, our sales and profitability, credit and financial strength ratings, and capital and liquidity positions.

Execution Risk
Our business strategies and plans are dependent on the successful execution of organizational and strategic initiatives designed to support the growth of our business. Our ability to manage the execution of these initiatives effectively and prioritize initiatives directly affects our ability to execute our strategies. Identifying and implementing the right set of initiatives is critical to achieving our Business Plan targets. Failure to identify and implement the right set of initiatives could also lead to cost structure challenges and inability to achieve our growth objectives.

Distribution Risk
Failure to achieve planned distribution scale could materially impact our financial and strategic objectives. This includes the inability to attract and retain intermediaries and agents at a cost that is financially feasible to the Company, or to develop online sales and Client support capabilities and technologies. Distribution risk may also be influenced where our distribution or product strategy and related services (including online sales and Client support capabilities and technologies) are not developed, modified or executed in line with our strategic objectives or in consideration of the changes in Client behaviour or our regulatory environment. In addition, the lack of a well-diversified distribution model in the jurisdictions in which we do business may cause over-reliance on agency channel or key partners.

Risks Relating to Mergers, Acquisitions, Divestitures and Strategic Investments
We regularly explore opportunities to selectively acquire other businesses or to divest ourselves of all or part of certain businesses, in support of our growth and strategic objectives. Any transaction carries risks associated with economic, operational, strategic, financial, tax, legal, regulatory, compliance, environmental and social, and other factors.

There is a risk that we may be unable to make an appropriate acquisition in a desired market or business line or unable to realize the financial and strategic benefits of the transactions due to competitive factors, regulatory requirements or other aspects. There is a risk that the capital utilized to finance any transaction may limit our ability to deploy further capital to pursue other opportunities and initiatives. These risks could adversely impact our ability to achieve our financial and strategic objectives.

Our ability to realize the contemplated economic, financial, and strategic benefit of any transaction that we enter into is contingent on several factors. These include the effective separation and/or integration of the transferred businesses, restructure and/or reorganization of related businesses, and retention of key personnel to effectively execute these transactions. In addition, post-closing activities and the harmonization of any differences in organizational culture may require the dedication of significant management resources, which may distract management’s attention from our day-to-day business. Further, anticipated synergies and other benefits may not materialize due to a failure to successfully integrate the acquired businesses with our existing operations. Any of these risks, if realized, could prevent us from achieving the expected outcomes from a transaction and impact our financial and strategic objectives.

To mitigate these risks, we have established procedures to govern the evaluation, execution and integration of mergers and acquisitions transactions. Regular updates on execution and integration risks relating to these transactions are provided to the Board, its Committees and senior management teams, as appropriate, along with any mitigants developed to address such risks.

Competitive Environment
Competition from insurance companies, banks, asset managers, mutual fund companies, financial planners and other service providers (including new entrants and non-traditional financial services companies) is intense, and could adversely affect our business in certain countries.

The businesses in which we engage are highly competitive and our ability to sell our products is dependent on many factors, including scale, price and yields offered, distribution channels, digital capabilities, financial strength ratings, range of product lines and product and service quality, brand strength, investment performance, historical dividend levels and the ability to provide value added services to distributors and Clients. In certain markets, some of our competitors may be superior to us on one or more of these factors. Our competitors have significant
70 December 31, 2023 Sun Life Financial Inc. MANAGEMENT'S DISCUSSION & ANALYSIS potential to disrupt our business through targeted strategies to reduce our market share which may include targeting our key people or bancassurance partners and other distributors or aggressively pricing their products.


Our ability to achieve our Business Plans and strategies depends significantly upon our capacity to anticipate and respond quickly to these competitive pressures.

Technology is driving rapid change in the financial services sector and is enabling new entrants to compete or offer services to our competitors to enhance their ability to compete in certain segments of the insurance, wealth and asset management markets. The emergence of new technologies such as robotic process automation, artificial intelligence, blockchain and advanced analytics may have an impact on the financial services sector and how companies interact with their stakeholders. Our current competitors or new entrants may use these or other new technologies to provide services in various areas such as customized pricing, proactive outreach to Clients and targeted marketing in order to strengthen their Client relationships and influence Client behaviour. The impact of disruption from changing technology and innovation by traditional and non-traditional competitors who may offer a better user experience, functionality or lower priced products and may have lower distribution costs will require us to adapt at a more rapid pace and may create margin pressures. The risk of disruption may also impact our distribution models as new and low cost digital-based business models emerge in connection with the distribution of financial services and products, such as insurtechs and robo-advisors. These risks are evolving rapidly with an increasing number of digital users and are difficult to anticipate and respond to proactively, and may adversely impact our profitability and financial position.

Investment Performance
Investment performance risk is the possibility that we fail to achieve the desired return objectives on our investment portfolio, or that our asset management businesses fail to design or execute investment strategies in order to achieve competitive returns on the products and managed accounts offered by these businesses. Failure to achieve investment objectives may adversely affect our revenue and profitability through slower growth prospects and adverse impacts on policyholder or Client behaviour.

Changes in Legal and Regulatory Environment
Most of our businesses are subject to extensive regulation and supervision. Changes to legislation, regulations or government policies, or the manner in which they are interpreted or enforced, may require that we make significant changes to our strategy and may result in increased implementation costs and diversion of resources to manage the change. These changes could impact financial reporting, accounting processes, capital requirements, the regulatory framework for our products and services, the regulation of selling practices, sales intermediaries and product offerings, solvency requirements, executive compensation, and corporate governance practices and could impose restrictions on our foreign operations (such as limits on foreign ownership of local companies). All of these changes could have an adverse effect on our business and operations. Our failure to comply with existing and evolving regulatory requirements could also result in regulatory sanctions and could affect our relationships with regulatory authorities and our ability to execute our business strategies and plans.

Environmental and Social Risk
Our financial performance, operations, and reputation may be adversely affected if we do not adequately prepare for the direct or indirect impacts of environmental and social risks. Environmental and social risks include but are not limited to environmental damage on properties owned or managed by us, climate change-related physical and transition risks, as well as issues of public health and inequality. These risks may occur in our direct operations, investing activities or other areas of our value chain.

Business units in our Asset Management pillar integrate ESG considerations in their investment decision-making for Sun Life assets and Client assets, where applicable. Existing ESG risks are considered, subject to data availability and materiality, in initial and ongoing reviews and assessments of public equities, public fixed income, private fixed income, real estate, infrastructure and commercial mortgage investments, among others. In addition, we monitor our third-party managers in the asset management, general account and fund platform businesses through our International Investment Centre (“IIC”). In the due diligence and monitoring of third-party managers, the IIC, functioning as an investment research and consulting group, assesses each manager’s consideration of ESG risks in its investment processes, as well as other relevant sustainability factors, and monitors them on an ongoing basis. These activities may be undertaken on behalf of, or in partnership with, the relevant Sun Life businesses. These businesses may also undertake their own due diligence activities.

We engage in and monitor environmental, social and broader sustainability developments in part through our participation as a signatory to the United Nations-supported Principles for Responsible Investment ("PRI"), United Nations Environment Programme - Finance Initiative ("UNEP FI"), including the Principles for Sustainable Insurance, and CDP.

In line with our strategy and our Purpose, Sun Life aims to drive further actions that create a cleaner, more inclusive, and sustainable future. Strong governance will help us deliver on our commitments and remain accountable to our stakeholders:

•Our Chief Sustainability Officer (“CSO”) leads enterprise-wide efforts to embed sustainable practices across our businesses.
•Our Executive Sustainability and Climate Change Council (“ESC”), chaired by our CSO, is composed of senior executives from Sun Life’s Global Leadership Team. The ESC is the decision-making body for the approval of cross-enterprise sustainability programs and issues management (e.g., human rights), as well as external commitments and targets including related progress oversight (e.g., net zero, sustainable investing, diverse supplier spend). ESC members also provide oversight on the company’s implementation of OSFI Guideline B-15: Climate Risk Management and development of the enterprise climate transition plan.
•Our Global Sustainability Leadership Team (“GSLT”) is composed of senior executives from each of our business groups and key functions. The GSLT advises on and implements our Sustainability Strategy.
We report on sustainability performance, including reporting related to climate change and other environmental and social issues, in our annual Sustainability Report, which is published in tandem with our Annual Report and is available at sunlife.com/sustainability.

Climate Change
Climate change is one of the defining issues of our time. Governments, regulators, investors, Clients and other stakeholders are rapidly increasing efforts to tackle this global issue. We believe that it is incumbent upon us to respond and to take actions that support the goal of the Paris Agreement to limit the global temperature increase in this century to well below 2 degrees Celsius compared to pre-industrial levels and to pursue efforts to limit the temperature increase to 1.5 degrees Celsius above pre-industrial levels.

                 MANAGEMENT'S DISCUSSION & ANALYSIS Sun Life Financial Inc. December 31, 2023 71


The commitments we make to our Clients can often extend decades into the future. For this reason, we must account for climate-related risks across our operations and investments. These risks are likely to intensify and spread as climate-related impacts escalate in frequency and severity.

Meaningful climate action is essential to delivering on our Purpose of helping our Clients achieve lifetime financial security and live healthier lives. Our Purpose can best be realized through the integration of this mindset across our businesses, and through working collaboratively with other stakeholders towards a common goal of mitigating and adapting to the effects of climate change. Sun Life is doing its part to support the transition to a low-carbon economy and to ensure our organization is resilient to climate change. We set an enterprise-wide goal to achieve net-zero greenhouse gas (“GHG”) emissions by 2050 as well as multiple interim targets across our businesses (refer to Metrics and Targets for additional details).

Our approach to climate change includes the following elements:
•We recognize that as a long-term investor, we have the opportunity to be part of the solution to this global challenge and invest proactively in assets and businesses that support the transition to a low-carbon economy.
•We are committed to advocacy and collaboration with governments, regulators, investors and industry leaders to develop supportive net-zero programs and policies that pave a path towards decarbonization.
•We assess climate-related impacts on our businesses and investments with the aim of prudently managing the associated risks. We acknowledge the challenges of uncertainty and imperfect data to inform decision making.
•We advocate for better data and disclosures, so we can make better-informed assessments of climate-related risks. We support the actions of regulators, including OSFI, to align their reporting requirements to the International Sustainability Standards Board’s IFRS S1 and S2, and welcome ongoing efforts to improve disclosure standards.
•We commit to continuously improving our climate-related measurement, monitoring and reporting.
•We are focused on driving climate action and strengthening the resilience of our own operations around the world, as well as the properties that we own in our investment portfolio.

We commit to working together across industries, with our Clients, investees and other stakeholders to all do our part in addressing the climate crisis. We are working to understand the solutions to this complex, global challenge. Our approach to climate change will evolve over time, as we continue to build our internal expertise, obtain high-quality and industry-relevant data, and further align to external developments and regulatory requirements.

The following sets out our climate-related disclosures in line with the Task Force on Climate-related Financial Disclosures (“TCFD”) recommendations, which are structured around four themes that represent core elements of how organizations operate: governance, strategy, risk management, and metrics and targets.

Governance

The Board uses reports from the Board Committee Chairs (detailed below) and other presentations by management and external experts, to decide on the nature and extent of its input and to provide challenge, advice and guidance to senior management on the enterprise approach to climate change. In 2023, climate-related topics were reviewed by the Board or a Committee of the Board at each of the quarterly meetings as well as the annual board strategy meeting either as part of dedicated agenda topics on Sun Life’s Business and Strategic Plans, including Sun Life’s Sustainability Strategy, or as part of various committee, officer and business group reports. The Board has received climate change training and education focused on sustainability-related matters, including board oversight on the impact of climate-related risks on asset management and insurance and on the impact of ESG on board governance and compensation.

Three Board Committees have oversight over aspects of climate change:
•The Governance, Investment & Sustainability Committee of the Board ("GISC") assists the Board with oversight of sustainability matters, including those related to climate. The GISC is responsible for reviewing and approving Sun Life's Sustainability Policy, overseeing progress against Sun Life's Sustainability Strategy and commitments (including decarbonization targets), reviewing and recommending Board approval of the annual Sustainability Report and the annual CSO plan, and overseeing the development and implementation of Sun Life’s Climate Transition Plan. In addition, the GISC reviews any material issues related to sustainability raised by management throughout the year, including climate-related matters.
•The Risk Committee of the Board assists the Board with enterprise-wide oversight of the management of current and emerging risks, which may include climate-related risks and, broadly, environmental risks.
•The Audit Committee reviews ESG disclosures (including climate-related disclosures) required to be included in Sun Life’s financial disclosure documents, and reviews management's quarterly reports on the effectiveness of Sun Life's internal controls over financial reporting, including any evolving standards over ESG disclosures.

At the management level, the CSO, Chief Risk Officer (“CRO”), and Chief Investment Officer (“CIO”) play key roles in assessing and managing climate-related risks and opportunities. Additional committees are in place at SLC Management and MFS to support these activities.
•Our CSO has overall accountability for sustainability, including climate change, across the enterprise. This accountability includes setting the strategy and governance framework for our organization. The CSO chairs our ESC and GSLT. Sun Life’s Vice President of Climate Change and Environmental Impact reports directly to the CSO and oversees the development and implementation of the enterprise-wide climate change strategy, climate risk and decarbonization performance and reporting functions.
•Our CRO is responsible for leading the Risk Management function (as noted above in Risk Management sections 2 and 7). Key and emerging risks are monitored and reported to the Risk Committee of the Board.
•Our CIO chairs the Sustainability Committee and Sustainable Investment Council within SLC Fixed Income. The Sustainability Committee is responsible for overseeing the direction, priorities and implementation of sustainable investing initiatives across SLC Fixed Income. The Sustainable Investment Council, composed of investment team leaders, is a sub-committee of the Sustainability Committee. It is the steering body for ESG integration in SLC Fixed Income’s investment processes, representing and working across asset class teams.
•The SLC Risk Committee provides oversight of SLC Management’s investment advisors (which includes SLC Fixed Income, InfraRed, BGO, Crescent, and AAM), operational, investment, business and strategic risks, including those relating to ESG.
•MFS has oversight committees to provide strategic leadership and support the effective integration of sustainability across MFS. The MFS Sustainability Executive Group provides strategic leadership concerning MFS’ sustainability strategy. It includes various senior leaders responsible for the integration of sustainability across the firm. MFS also has committees that are a part of its
72 December 31, 2023 Sun Life Financial Inc. MANAGEMENT'S DISCUSSION & ANALYSIS existing committee governance structure.


These committees are devoted to the implementation of specific aspects of MFS’ sustainability strategy, including ESG integration strategy and policies, engagement, proxy voting and ESG Client and corporate strategies and policies.

Strategy

As part of our updated enterprise Sustainability Strategy, climate change has been elevated as a cross-cutting lens connected to our Purpose and our core pillars of Financial Security, Healthier Lives, Sustainable Investing and foundation as a Trusted and Responsible Business. Meaningful climate action is essential to achieving our Purpose and we are committed to doing our part to support the transition to a low-carbon economy and ensure we are an organization resilient to climate change. The strategy sets the foundation for how we will do this while creating competitive advantage and differentiation for our business.

Climate change has a variety of implications for our business as an asset management and insurance company, especially when considering the impacts of climate change on human health. As an organization that provides life and health insurance products to Clients across the globe, we are keenly aware of the vast implications of climate change on our Clients’ well-being. The increased severity and frequency of extreme weather events and the chronic shift towards higher temperatures have significant impacts on health. Heat-related deaths and hospitalizations have increased over the last decade and will continue to increase as temperatures rise. Lower air quality from pollutants, rising temperatures and wildfires can have long-term implications on respiratory health. Emotional distress, anxiety and trauma caused by these extreme weather events can also negatively impact mental health.

Changing precipitation and ensuing floods, droughts and wildfires directly impact food crops and can lead to food insecurity and malnutrition. Changing precipitation and warming temperatures also increase the proliferation of pests, causing direct damage to food crops, while also increasing the transmission of vector-borne disease like dengue fever and Zika virus.

From an investment perspective, climate change presents both risks and opportunities. A transition to a low-carbon economy could affect asset values over time. Among other impacts, portfolio investments in coal, conventional oil and oil sands producers, utilities and related fossil fuel industries, railways and pipelines, as well as markets that depend on these industries, may be subject to additional financial risk as a result of changes in regulation, cost of capital, consumer preferences, technological or business model disruption, etc. This may lead to lower overall profitability and/or stranded assets (assets for which the investment costs cannot be recovered as intended).

Physical climate impacts could affect investments in real assets such as real estate, commercial mortgages, and infrastructure, as well as our own operations, and operations and revenues of our Clients and businesses across our portfolios. Risks may result from increased severity and frequency of extreme weather events and from longer-term shifts in climate patterns, leading to declining asset values, increasing insurance costs or uninsurability.

For further discussion of potential climate-related risks, please refer to Environmental and Social Risk in Sun Life’s 2023 Annual Information Form (“AIF”) under Risk Factors – Business and Strategic Risk.

Climate-related opportunities include those related to sustainability and green bonds, investments in developing resilient and adaptive real estate and infrastructure as well as renewable energy and other assets and businesses that support or benefit from a transition to a low-carbon economy. Many companies and industries are benefiting from climate change-related tailwinds, such as mobility (vehicle electrification), energy efficiency services, battery technology and renewables. Through our asset managers’ ESG integration efforts, we seek to identify these investment opportunities in both public and private markets, including opportunities in securitized investments and direct investments (real estate, traditional public infrastructure, and other types of public infrastructure such as sustainable agriculture).

Climate-related risks and opportunities are considered in our asset management businesses’ investment processes and in our financing activities. In 2019, we were the first life insurer globally to issue a sustainability bond and in 2023, we issued our second sustainability bond. Issuing sustainability bonds demonstrates our commitment to embedding sustainability into our business while contributing positively to society and advancing technologies that enable the transition to a low-carbon economy. Through our Asset Management pillar, we believe we are well-positioned to support Clients who want to invest in the net-zero transition. Asset management is delivered by MFS as well as the businesses that operate under the SLC Management brand: SLC Fixed Income, InfraRed, BGO, Crescent, and AAM. Climate-related investment strategies for our asset managers are highlighted below:

•MFS, as a long-term investor in public issuers seeking to understand the duration and stability of financial returns, assesses climate change at both the issuer level and portfolio level. As with all risks and opportunities, MFS' assessment of environmental issues such as climate change begins with in-depth fundamental issuer and industry analysis. Climate change and regulations associated with climate change are materially impacting many businesses’ revenue growth, margins and returns, cash flows, capital expenditures and valuation. As long-term investors seeking to allocate capital responsibly, MFS can use a variety of tools to increase the rate of change, which MFS believes will improve investment results and create value for Clients. MFS also regularly engages with issuers to encourage better disclosure and management of climate-related risks and opportunities. MFS’ Strategic Climate Action Plan sets forth its investment philosophy with regard to the risks and opportunities associated with climate change, along with its expectations for issuers to have a climate plan to reduce or eliminate their emissions toward a goal of achieving net zero.
•SLC Fixed Income offers its institutional Clients opportunities to invest in sustainable infrastructure through its private fixed income investments. Sustainable infrastructure categories include renewable energy, energy efficiency and clean transportation. SLC Fixed Income engages with certain portfolio companies, where relevant, to help inform its understanding and management of climate-related risks and opportunities. SLC Fixed Income’s Climate Report sets forth its investment philosophy and associated disclosures with regard to risks, strategies and targets associated with climate change.
•InfraRed invests in and manages social infrastructure, low-carbon generation, renewable energy, energy efficiency and energy enabling infrastructure projects, which advances its sustainable investment options for institutional Clients while complementing its focus on sustainable investing and climate change. InfraRed also actively assesses the physical-related climate risks associated with its existing and new investments in order to actively manage the climate resilience of the essential infrastructure projects it manages.
•BGO analyzes climate-related risks for activities that are in scope using the following tools and programs. To help identify exposure to physical climate risks for certain new acquisitions, BGO utilizes Moody’s ESG Solutions as a Climate Risk Provider. Included in the assessment are projections of exposure to floods from extreme precipitation, hurricane-force winds, sea level rise, water stress,
                 MANAGEMENT'S DISCUSSION & ANALYSIS Sun Life Financial Inc. December 31, 2023 73


heat stress, wildfires, and earthquakes. Risks identified in this assessment are included in underwriting with details of what may be causing this risk and mitigation actions. As part of BGO’s ESG Risk Matrix for new acquisitions, assets are scanned for indicators that may impact transition risk, such as energy performance, GHG emissions, and the existence of any local regulations. Transition risk metrics such as utility price impacts and government regulations are continually monitored for certain assets at the property level through its sustainability data management systems.
•Crescent’s investment decisions are guided by Clients’ long-term interests, which are served through the incorporation of ESG considerations, including those related to climate change. Where possible, Crescent seeks to engage collaboratively with portfolio companies on topics such as understanding climate change risks and emissions intensity.

As longer-term investors, we believe that integrating climate change as a key element of our investment objectives can be a source of competitive advantage as it should lead to stronger risk-adjusted returns over time. The integration of climate change risks and opportunities may also result in stronger ESG investment ratings from groups such as PRI, Morningstar, GRESB and others, which can be key decision factors for Clients. Our asset managers may take the approach of active engagement and education to work with investee companies in their transition to net zero. SLC Fixed Income is a member of the Climate Engagement Canada and Climate Action 100+ investor initiatives. Through those initiatives and in its capacity as Sun Life’s primary general account asset manager, SLC Fixed Income engages with some of the world’s largest corporate GHG emitters with whom Sun Life has investments to support best practices around sustainability disclosures, and to better understand their management of climate-related risks and opportunities. MFS and Crescent are also signatories to Climate Action 100+.

For investment funds offered by the Sun Life Canada businesses, we recognize that our Clients are increasingly seeking a sustainable investment lens from our solutions. Our GRS business’ proprietary ESG integration evaluation framework helps sponsors of group retirement plans make informed decisions about the investment options they make available to their employees in their workplace plans. The evaluation framework uses detailed criteria in three key areas: firm policies, investment process and active ownership. SLGI evaluates its investment managers using similar criteria. This approach provides deeper insights into its investment managers’ direction on ESG matters and their ability to embed these considerations across all aspects of the investment decision process.

Sun Life’s general account, where Sun Life is the asset owner, is comprised of assets from proceeds of insurance policies. A series of publicly-disclosed climate-related investment beliefs and principles guide the investment decisions of the general account in-scope asset classes which have net-zero interim targets. When evaluating in-scope general account investments in carbon-intensive sectors, Sun Life will consider credible GHG reduction plans and alignment or commitment to alignment with net zero. Our in-scope general account investments prioritize companies that are either categorized as net zero aligned, aligning, or committed to aligning, informed by the Net Zero Investment Framework. We also regularly review the financial performance of our investments and incorporate non-financial metrics. Performance against GHG reduction targets, where material, are a part of this fundamental investment analysis and will inform our general account investment decisions. For more information, refer to Sun Life’s Net Zero by 2050: Sun Life’s Climate Journey report.

In addition to the asset management and investment activities above, our experience with climate scenario analysis also includes enterprise-wide testing as part of FCT(1). A focus of our FCT has been climate-related investment risks, which we believe are a larger and more immediate concern. More broadly, we continue to monitor emerging research on the scope and scale of climate-related life and health impacts as they remain a significant longer-term concern to our business. We expect to continue to build on our climate scenario testing in 2024. In addition to using climate scenarios in FCT, we continue to leverage learnings from our experience with climate scenario analysis including our participation in the pilot project between the Bank of Canada, OSFI, and a small group of Canadian financial institutions in 2021.

We engage on emerging climate regulation and policy impacting our business directly and through industry associations, such as the Canadian Life and Health Insurance Association, the American Council of Life Insurers and the Canadian Chamber of Commerce. We have advocated for improved climate-related financial disclosure and data, harmonization of emerging standards and regulations, and investments in data and scientific research on the link between climate change and life and health outcomes. Better and more consistent data across industries would allow for improved decision making and ultimately for capital to flow to those companies that are working to develop credible solutions for the transition to a low-carbon economy. In addition, we advocate for improving Canada’s sustainable finance market and expanding opportunities to invest in green buildings and sustainable infrastructure. We disclose our lobbying activities in compliance with regulatory obligations as determined by each jurisdiction.

In addition to the engagements above, our actuarial and sustainability teams, as well as our asset managers actively participate in industry consultations and working groups focused on scenario analysis and stress testing. We will continue to mature our climate scenario analysis capabilities as industry guidance, best practices, tools and our internal expertise grow.

Risk Management

Climate risk management is integrated into our Risk Framework, Governance, and supporting processes (as noted in preceding sections 1 through 8 and under Governance above). We continue to mature our climate risk management practices to ensure climate resiliency.

Our definition of climate risk includes physical impacts of climate change and impacts of the transition to a low-carbon economy. These impacts can include, but are not limited to, damage to owned and operated real assets including real estate and infrastructure, a reduction in the values of investments in public and private fixed income and non-fixed income assets tied to fossil fuels and carbon intensive industries, litigation risk to a company or sector in which we invest, health impacts to affected populations (which can affect long-term morbidity and mortality assumptions), and socio-economic, geopolitical and regulatory changes. We also include an assessment of climate change risk as part of our broader assessment of the risks associated with operating in various markets.




(1)Financial Condition Testing is a stress testing exercise to assess the future financial condition of Sun Life under adverse scenarios.
74 December 31, 2023 Sun Life Financial Inc.


MANAGEMENT'S DISCUSSION & ANALYSIS From an investment perspective, our asset managers integrate climate-related risks (where material to an issuer, industry and/or asset class) into the risk management process as they look to make long-term investments that are better positioned to withstand issues related to climate change from a financial materiality perspective. They incorporate a number of different analyses into their assessment of climate risks through both stand-alone analysis of physical risks by geographic region and through the assessment of business model and carbon transition risks. Climate-related risk categories monitored may include acute and chronic physical risks and transition risks related to current and emerging laws and regulation, changing technology, market and reputation risks or consumer preferences.

Each of our asset managers takes its own approach to identifying, assessing, monitoring and responding to climate-related risks and opportunities, based on the asset classes it invests in. Approaches are refined periodically. Examples of approaches include:

•Proprietary climate risk surveys to identify, assess and respond to climate-related risks and opportunities
•Portfolio and asset level risk analysis to inform investment decisions and resilience plans
•Scoring methodologies that look to standardize the assessment of transition risks
•Emissions data analysis
•Stranded asset modeling
•Real assets physical risk exposure assessment
•Carbon intensity monitoring and benchmarking
•Individual as well as collaborative engagements on topics such as decarbonization

Additionally, an environmental issue, whether caused by climate change or other factors, on a property owned or operated by us could have financial or reputational impacts. Our real estate asset manager maintains an environmental risk management program to help monitor and manage real estate investment assets from losses due to environmental issues and to ensure compliance with applicable laws. Where feasible, we maintain insurance policies to cover certain environmental risks on owned assets. We have implemented a business continuity program to facilitate the recovery of critical business operations if an environmental issue affects a location where we conduct operations. The Company’s corporate real estate group, together with our building owners and property managers, assesses the potential effects of climate change-related hazards and examines ways to improve the ability of our buildings to withstand these hazards. These hazards include tornadoes, flash floods, ice storms and coastline flooding.

Climate-related disclosure standards and regulatory requirements continue to be issued and evolve in the jurisdictions in which we operate. Potential divergence in expectations among regulators, as well as the pace of regulatory change in the area of climate change, could lead to additional risks. We continue to monitor our risk management practices and disclosures as new regulations and standards are implemented and as the external landscape continues to evolve. In addition, we participate in consultations with policymakers and regulators on policy and regulatory developments regarding climate-related disclosures.

Metrics and Targets

Sun Life has set a goal to achieve net-zero GHG emissions by 2050 for both its investments and operations. As an asset owner, Sun Life plans to achieve net-zero GHG emissions by 2050 for investments in its general account. Our approach for achieving net-zero emissions in the general account focuses on asset classes where we have access to quality data, established net-zero emissions methodologies and where we believe we can have the biggest real-world impact in reducing emissions. We use the Partnership for Carbon Accounting Financials (“PCAF”) Part A (Financed Emissions) methodology to calculate our financed emissions. In 2023, we set interim targets for the general account for 2030(1) for asset classes where there is industry guidance and we have the ability to have an immediate impact; this means our investments in listed corporate bonds (intensity and alignment targets), directly managed listed equities (intensity target), and commercial real estate (intensity target), which collectively cover 29% of Sun Life’s general account AUM(2). Our asset managers that are members of the Net Zero Asset Managers (“NZAM”) initiative have also set respective interim targets for the assets they manage. The NZAM initiative is an international group of asset managers committed to supporting the goal of net-zero emissions by 2050. NZAM members include MFS, SLGI, and SLC Management asset managers: SLC Fixed Income, InfraRed and BGO. Updated interim targets and a summary of our other commitments and progress towards net-zero GHG emissions are available in our Net Zero by 2050: Sun Life's Climate Journey report.

For our operations, we have set an interim target of a 50% absolute reduction of GHG emissions by 2030, relative to 2019(3). While we continue our efforts to reduce our operational GHG emissions, we purchase high-quality carbon offsets that are verified and additional (according to carbon standards) to compensate for the remaining emissions in our operations that we have yet to reduce. This approach of purchasing offsets is not part of our enterprise decarbonization strategy, but is one way to help manage the climate impact of our operations today while we work towards our interim 2030 operational target and enterprise-wide goal of net-zero GHG emissions by 2050.

Sun Life is continuing progress towards its target of $20 billion in new sustainable investments from 2021 to 2025 across its general account and Client investments, which are managed by SLC Management. Investments include, but are not limited to, renewable energy, energy efficiency, sustainable buildings, clean transportation, water management, and social infrastructure projects.

We report our progress on our operational emissions reduction targets and sustainable investment targets in our annual Sustainability Report available at www.sunlife.com/sustainability.

In 2023, the Board approved the addition of a Sustainability modifier to the Senior Executive Sun Share Unit Plan, which assesses performance over three years against four goals aligned to two of our Sustainability Pillars. Climate-related goals include sustainable investment and GHG emissions reduction in our operations.



(1)Relative to a 2019 baseline for intensity targets and a 2022 baseline for alignment target.
(2)As of December 31, 2019, Sun Life's general account invested assets AUM was $161.6 billion.
(3)Emissions resulting from global corporate offices and data centres as well as from business travel, inclusive of majority-owned Sun Life affiliate companies.
                 MANAGEMENT'S DISCUSSION & ANALYSIS Sun Life Financial Inc. December 31, 2023 75


Sun Life and majority-owned affiliate companies report global Scope 1 and 2 emissions from company-occupied real estate, data centres and real estate investments under our financial control (as defined in the GHG Protocol Corporate Accounting and Reporting Standard) as well as Scope 3 emissions (where data is available)(1) associated with business travel, real estate-related sources, and select asset classes within our general account in our annual Sustainability Report. We continue to advance the quality and availability of emissions data across our enterprise emissions inventory. All emissions reporting is aligned to the GHG Protocol Corporate Accounting and Reporting Standard using the financial control approach. Additional information on GHG emissions calculations can be found in Sun Life’s Financial GHG Reporting Methodology.

Please refer to Environmental and Social Risk in our AIF for additional climate-related risk discussion.

v. Operational Risk
Risk Description
Operational risk is the risk of loss (financial and non-financial) resulting from inadequate or failed internal processes, people and systems or from external events. Operational risk is present in all of our business activities and encompasses a broad range of risks as described below. Operational risk is embedded in the practices utilized to manage other risks and, therefore, if not managed effectively, operational risk can impact our ability to manage other key risks.

Operational Risk Management Governance and Control
We employ a wide range of operational risk management practices and controls, as outlined below:
•Operational risk governance practices are in place, including independent monitoring and review and reporting to senior management and the Board Committees.
•Risk appetite limits have been established in Operational Risk.
•Comprehensive Operational Risk Management Framework, Policies, guidelines and practices are in place.
•Our governance practices, corporate values, Code of Conduct and Company-wide approach to managing risk set the foundation for mitigating operational risks.
•Our Code of Conduct sets the tone for a strong ethical culture, and we regularly review and update the Code of Conduct to ensure that it continues to meet the expectations of regulators and other stakeholders. All our directors and employees must reconfirm annually their understanding of and commitment to comply with the Code of Conduct.
•We have established appropriate internal controls and systems for talent acquisition, rewards and development programs that attract, build and retain top talent and create strong succession plans as well as compensation programs, and we provide ongoing training to our people.
•We conduct regular monitoring of employee engagement to ensure we create and maintain a work environment where all employees are welcome and able to contribute effectively.
•Stress-testing techniques, such as FCT, are used to measure the effects of large and sustained adverse scenarios.
•We mitigate a portion of our operational risk exposure through our corporate insurance program by purchasing insurance coverage that seeks to provide insurance against unexpected material losses resulting from events such as criminal activity, property loss or damage and liability exposures, or that satisfies legal requirements and contractual obligations.
•Internal capital targets are established at an enterprise level to cover all risks and are above minimum regulatory and supervisory levels. Actual capital levels are monitored to ensure they exceed internal targets.

Specific operational risks and our risk management strategies are discussed below in further detail and in the Risk Factor section in the AIF.

Information Security and Privacy Risks
Information and technology are used in almost all aspects of our business and operations. As part of our Client strategy, we continue to enhance the digital side of our business to support and enable new business models and processes, that are more personal, proactive and predictive.

Our business and the successful implementation of our digital strategy are dependent on various factors including maintaining a secure environment for our Clients, employees and other parties' information. This requires the effective and secure use, management and oversight of information and physical assets. We engage with various stakeholders and leverage emerging technologies, including digital, mobile applications, cloud computing, artificial intelligence and robotic process automation. These technologies are used to collect, process and maintain information relating to business transactions and financial reporting, as well as the personal information of our Clients and employees. We also obtain services from a wide range of third-party service providers and have outsourced some business and information technology functions in various jurisdictions.

There continues to be an increasing number of information security compromises and privacy breaches across industry sectors, governments and individuals. The increasing scope and complexity of malicious activity poses a significant risk to our systems and these risks may be exacerbated by the breadth of our operations, our geographic footprint and the complexity of our technology systems. A serious security or privacy breach of either an internal or third-party service provider’s computer system that contains sensitive business, Client and/or employee information may result in business interruption, theft or misuse of confidential information, regulatory penalties and scrutiny, litigation, reputational damage and may have an adverse impact on current and future business opportunities with our Clients, employees and business relationships. We continue to actively monitor for increases in malicious activity due to escalating geopolitical tensions across the globe.



(1)Scope 3 emissions are related to global business travel (air, rail, car-rental and employee-claimed mileage), utilities for company-occupied real estate that are not under our financial control, water consumption and waste generated at real estate investments, as well as select asset classes within our general account.
76 December 31, 2023 Sun Life Financial Inc. MANAGEMENT'S DISCUSSION & ANALYSIS We continue investing in people, processes and technology to strengthen our abilities to respond to the evolving threat landscape.


Our Information Security framework is overseen by the Chief Information Security Officer, supported by senior leadership and by our Operational Risk Management Framework. Our information security framework and governance controls (policies, procedures, training) are aligned with recognized industry standards and are compliant with applicable laws and regulations. Our Chief Privacy Officer oversees the global privacy program and sets direction for privacy compliance across the enterprise. Over 30 Privacy Officers across the enterprise help our businesses make privacy-related decisions.

Our well-established security controls and processes are intent on protecting our information and computer systems and the information entrusted to us by our Clients and employees. Our protection strategy leverages information security risk assessments and privacy impact assessments to evaluate potential risks. The security framework also includes technology and process safeguards and regularly promotes secure behavioural practices. As part of our layered security approach, we deliver general security awareness training sessions to all employees every year that is reinforced with regular awareness resources and activities.

Many jurisdictions in which we do business are developing and implementing cyber security reporting requirements and more stringent consumer privacy legislation, many with greater enforcement powers for regulators and higher fines and penalties. Our global privacy program monitors adherence to our global privacy commitments, local laws and local privacy policies. We have also established a network of privacy officers across the Company who monitor emerging privacy legislation and provide guidance on handling personal information and help manage, report and resolve any privacy incidents that may occur. We also conduct privacy training, provide regular monitoring and reporting and carry cyber risk insurance to help mitigate the impact of privacy incidents.

Human Resources Risk
Our ability to achieve business objectives can be adversely affected if we are unable to attract, retain or effectively deploy resources with the in-depth knowledge and necessary skills required, or are unable to design compensation and talent programs that effectively drive employee behaviour and shape corporate culture. Failure to manage Human Resources risk can also lead to direct financial and reputational loss including losses arising from activity that is inconsistent with Human Rights or employment laws or health and safety regulations.

To mitigate this risk, we have comprehensive Human Resource policies, practices and programs in place to ensure compliance with employment legislation, minimize the risk of employee misconduct, and proactively develop employee skills, capabilities and behaviours to meet future business needs.

Regulatory Compliance, Legal and Conduct Risk
We are subject to extensive regulatory oversight by financial services regulators in the jurisdictions in which we conduct business. Failure to comply with applicable laws or to conduct our business consistent with changing regulatory or public expectations could adversely impact our reputation and may lead to regulatory investigations, examinations, proceedings, settlements, penalties, fines, restrictions on our business, litigation or an inability to carry out our business strategy.

Our Chief Compliance Officer oversees our comprehensive Enterprise-wide compliance framework, which is aligned with guidance from OSFI and other regulators. This framework promotes proactive, risk-based management of compliance and regulatory risk, and includes Enterprise and business segment policies and operating guidelines, programs to promote awareness of laws and regulations that impact us, ongoing monitoring of emerging legal issues and regulatory changes and training programs. The employee training programs include anti-money laundering and anti-terrorist financing, anti-bribery and corruption, fraud, privacy and information security risk management. Effective governance, oversight and implementation is a coordinated effort between first and second lines of defence functions. Second line oversight and effective challenge relies on a network of compliance officers. The Chief Compliance Officer reports regularly to the Board and Board Committees on the health of the compliance program, key compliance risks, emerging regulatory trends, escalation of significant issues and key risk indicators.

Information Technology Risk
The use of technology and computer systems is essential in supporting and maintaining business operations. We use technology to support virtually all aspects of our business and operations. The rapidly changing business environment increases the risk of our technology strategy not being agile enough to adapt to new business demands in a timely manner leading to financial losses, increased costs and the inability to meet Client needs.

Initiatives supporting our business strategy rely on developing innovative information technology solutions and upgrading our existing systems on a timely basis to meet business needs. Although every reasonable precaution is taken to ensure information technology systems remain available, stable and current, it is not possible to fully eliminate all risk. Some changes and upgrades are extremely complex and there is a chance that an undetected technical flaw may exist, which, when implemented, stops or disrupts critical information technology systems or business applications.

Third-Party Risk
We engage in a variety of third-party relationships, including with distributors, independent contractors, outsourcing service providers and suppliers. Our profitability or reputation could be impacted if these third parties are unable to meet their ongoing service commitments or fail to perform to expected standards.

To manage these risks, we have established Company-wide policies and guidelines which are consistent with OSFI's and other local regulatory requirements, and which set out our requirements to identify, assess, manage, monitor and report on third-party risks. Our program includes third-party risk assessments and enhanced due diligence if a supplier will have access to any personal data and/or confidential information or access to non-public systems. The key elements and risks associated with the third party are documented in the form of a written agreement, and the company monitors performance of its third parties in a manner that is commensurate to the size, risk, scope and complexity of the third-party relationship.

                 MANAGEMENT'S DISCUSSION & ANALYSIS Sun Life Financial Inc. December 31, 2023 77


Business Disruption Risk
To conduct operations, our businesses are dependent on the availability of trained employees, physical locations and access to technology. A significant business disruption to our operations can result if one or more of these key elements are negatively impacted. System disruptions as well as unanticipated events, including pandemics, can negatively affect staff, preventing them from getting to work or from operating business processes.

To manage this risk, we have implemented a business continuity program to facilitate the recovery of critical business operations. This program encompasses business continuity, crisis management and disaster recovery planning. Our policy, guidelines and operating procedures establish consistent processes designed to ensure that key business functions can continue and normal operations can resume effectively and efficiently should a major disruption occur. In addition, to regularly update and test business continuity plans for critical business operations, we conduct mandatory business continuity awareness training for all employees annually and have off-site backup facilities and failover capability designed to minimize downtime and accelerate recovery time in the event of a major disruption.

Model Risk
We use complex models to support many business functions including product development and pricing, capital management, valuation, financial reporting, planning, hedging, asset-liability management, risk management and advanced analytics (such as artificial intelligence, predictive modeling and decision making algorithms). Model risk is the risk of loss, either in the form of financial loss, inappropriate or poor business decisions, damage to reputation, or other adverse impact, arising from inaccurate model outputs or incorrect use or interpretation of model outputs.

To manage model risk, we have established robust, Company-wide model risk management procedures over the models' life cycle with respect to building, using, changing and retiring models. The policy and operating guidelines set out minimum, risk-based requirements to ensure that models are effectively controlled, maintained and appropriately understood by users.

Information Management Risk
As an international provider of financial services, we deal with extensive information across a number of countries. Information management risk is the a) inability to capture, manage, retain and appropriately dispose of business records, b) the inability to provide data that is valid, complete, accurate, consistent, unique, or timely to support business decisions, and c) the inability to manage data location and cross-border access appropriately. Failure to manage these risks could have financial or reputational impacts, and may lead to regulatory proceedings, penalties and litigation. To manage and monitor information management risk, we have a data governance framework, which includes a records management program, data quality best practices, and data residency controls.

We continue to evolve our risk management best practices to manage risks associated with Generative-AI as we identify use cases and run experiments designed to identify opportunities.

vi. Liquidity Risk
Risk Description
Liquidity risk is the possibility that we will not be able to fund all cash outflow commitments and collateral requirements as they fall due. This includes the risk of being forced to sell assets at depressed prices resulting in realized losses on sale. This risk also includes restrictions on our ability to efficiently allocate capital among our subsidiaries due to various market and regulatory constraints on the movement of funds. Our funding obligations arise in connection with the payment of policyholder benefits, expenses, reinsurance settlements, asset purchases, investment commitments, interest on debt, and dividends on common and preferred shares. Sources of available cash flow include general fund premiums and deposits, investment related inflows (such as maturities, principal repayments, investment income and proceeds of asset sales), proceeds generated from financing activities, and dividends and interest payments from subsidiaries. We have various financing transactions and derivative contracts under which we may be required to pledge collateral or to make payments to our counterparties for the decline in market value of specified assets. The amount of collateral or payments required may increase under certain circumstances (such as changes to interest rates, credit spreads, equity markets or foreign exchange rates), which could adversely affect our liquidity.

Liquidity Risk Management Governance and Control
We generally maintain a conservative liquidity position and employ a wide range of liquidity risk management practices and controls, which are described below:
•Liquidity risk governance practices are in place, including independent monitoring and review and reporting to senior management and the Risk Committee.
•Liquidity is managed in accordance with our Asset Liability Management Policy and operating guidelines.
•Liquidity contingency plans are maintained for the management of liquidity in a liquidity event.
•Stress testing is performed by comparing liquidity coverage risk metrics under a one-month stress scenario to our policy thresholds. These liquidity coverage risk metrics are measured and managed at the enterprise and legal entity levels.
•Stress testing of our collateral is performed by comparing collateral coverage ratios to our policy thresholds.
•Cash Management and asset-liability management programs support our ability to maintain our financial position by ensuring that sufficient cash flow and liquid assets are available to cover potential funding requirements. We invest in various types of assets with a view of matching them to our liabilities of various durations.
•Internal capital targets are established at an enterprise level to cover all risks and are above minimum regulatory and supervisory levels. Actual capital levels are monitored to ensure they exceed internal targets.
•We actively manage and monitor our capital and asset levels, and the diversification and credit quality of our investments.
•Various credit facilities for general corporate purposes are maintained.


78 December 31, 2023 Sun Life Financial Inc.      MANAGEMENT'S DISCUSSION & ANALYSIS         


We are subject to various regulations in the jurisdictions in which we operate. The ability of SLF Inc.'s subsidiaries to pay dividends and transfer funds is regulated in certain jurisdictions and may require local regulatory approvals and the satisfaction of specific conditions in certain circumstances. Through effective cash management and capital planning, SLF Inc. ensures that its subsidiaries, as a whole and on a stand-alone basis, are properly funded and maintain adequate liquidity to meet obligations, both individually and in aggregate.

Based on our historical cash flows and liquidity management processes, we believe that the cash flows from our operating activities will continue to provide sufficient liquidity for us to satisfy debt service obligations and to pay other expenses as they fall due.

Maturity Analysis for Insurance Contracts
The following tables present the undiscounted estimated future cash flows of insurance contract and reinsurance contract held assets and liabilities on our Consolidated Statements of Financial Position. These cash flows include estimates related to the timing and payment of death and disability claims, policy surrenders, policy maturities, annuity payments, minimum guarantees on segregated fund products, policyholder dividends, amounts on deposit, commissions and premium taxes offset by contractual future premiums and fees on in-force contracts. These estimated cash flows are based on the best estimated assumptions used in the determination of insurance contract and reinsurance contract held assets and liabilities. Due to the use of assumptions, actual cash flows will differ from these estimates. Amounts payable on demand, which includes amounts on deposit, dividends on deposit, outstanding claims and policyholder account values, are included in the 1 year or less time band. The amounts included in the table differ from the carrying value of the portfolio due to discounting, risk adjustments, and liability for remaining coverage for contracts using the premium allocation approach.

Amounts in this table include the liability for incurred claims for contracts measured using the PAA, but exclude the liability for remaining coverage for contracts measured using the PAA.

2023 vs. 2022

Canada
Canada's revenue increased $18.4 billion in 2023, primarily driven by higher net investment income from fair value changes of invested assets.

U.S.
U.S.'s revenue increased $8.0 billion in 2023, primarily driven by higher net investment income from fair value changes of invested assets and higher insurance revenue.

Asset Management
Asset Management's revenue increased $0.4 billion or 6% in 2023, driven by higher fee income in SLC Management partially offset by lower fee income in MFS.

Asia
Asia's revenue increased $7.1 billion in 2023, primarily driven by higher net investment income from fair value changes of invested assets.

Corporate
Corporate's loss of $0.1 billion in 2023 compared to a loss of $1.2 billion in 2022, was primarily driven by the sale of Sun Life UK.

ii. Revenue
Revenues are primarily derived from life and health insurance, investment management and annuities, and mutual funds, as well as Corporate investments and earnings on capital not attributed to a strategic business segment. Total revenue is comprised of: (i) insurance revenue; (ii) net investment income; and (iii) fee income. Total revenue excludes investment result for insurance contracts for account of segregated fund holders.

Insurance revenue is comprised of the portion of premiums that cover expected claims and directly attributable expenses in the period, as well as the release of risk adjustment and the amortization of CSM for the period. Insurance revenue excludes the portion of premiums that cover repayment of investment components.

Net investment income is comprised of interest income, dividends, realized and unrealized gains and losses, and other investment income earned on general fund assets. Net investment income, such as net rental income, fair value changes, and foreign exchange gains (losses) are also earned from non-financial instruments. Net investment income can experience volatility arising from the quarterly fluctuation in the
82 December 31, 2023 Sun Life Financial Inc. MANAGEMENT'S DISCUSSION & ANALYSIS value of FVTPL assets and foreign currency changes on assets and liabilities, which may in turn affect the comparability of revenue from period to period.


The change in fair value of FVTPL assets is driven largely by market-related factors such as interest rates, credit spreads and equity returns. The debt and equity securities that support insurance contract liabilities are generally designated or classified as FVTPL and changes in fair values of these assets are recorded in net investment income in our Consolidated Statements of Operations. Changes in the fair values of the FVTPL assets supporting insurance contract liabilities are largely offset by a corresponding change in the liabilities excluding those for account of segregated fund holders.

Fee income includes distribution fees, fund management and other asset-based fees, primarily earned in the Asset Management segment. Fee income also includes administrative service and other fees primarily earned in the Canada and U.S. segments. Premium and deposit equivalents from administrative services only ("ASO"), as well as deposits received by the Company on investment contracts such as segregated funds, mutual funds and managed funds are not included in revenue; however, the Company does receive fee income from these contracts, which is included in revenue. Fee income and ASO premium and deposit equivalents are an important part of our business and as a result, revenue does not fully represent sales and other activity taking place during the respective periods.

Insurance revenue increased $2.5 billion or 13%, primarily driven by higher health insurance revenue in the U.S.

Net investment income increased $32.2 billion mainly from fair value changes of invested assets reflecting the impact of interest rates, credit spreads, and equity markets.

i. Changes in items related to the Statement of Financial Position
Total general fund assets was $204.8 billion as at December 31, 2023 (December 31, 2022 - $198.3 billion), primarily reflecting an increase in the fair value of invested assets driven by declining interest rates.

The net liabilities balance for insurance contracts issued(2) was $135.5 billion as at December 31, 2023 (December 31, 2022 - $131.2 billion), primarily reflecting insurance finance income and expenses and cashflows, partially offset by dispositions and the change in insurance service result.

Total shareholders' equity, including preferred shares and other equity instruments, is $23.6 billion as at December 31, 2023 (December 31, 2022 - $22.5 billion). The change in total shareholders' equity included:

ii. Off-Balance Sheet Arrangements
The principal purposes of these arrangements are to earn management fees and additional spread on a matched book of business and to reduce financing costs.

Quarterly Comparison - Q4'23 vs. Q4'22
Underlying net income(1) of $983 million increased $91 million or 10%, driven by:
•Wealth & asset management(1) up $27 million: Higher Asset Management fee-related earnings and higher investment income driven by volume growth and an increase in yields.
•Group - Health & Protection(1) up $44 million: Business premium growth in the U.S. and Canada, improved disability experience in Canada, and higher investment contributions in the U.S., partially offset by lower results in U.S. Dental.
•Individual - Protection(1) up $53 million: Business growth reflecting good sales momentum in Asia, and higher investment contributions in Canada, partially offset by lower earnings due to the sale of Sun Life UK(2).
•Corporate expenses & other(1) $(33) million increase in net loss driven by higher operating expenses reflecting business growth and continued investments in the business, partially offset by a lower effective tax rate.
•Higher earnings on surplus primarily driven by higher net interest income and lower realized losses.

Reported net income of $749 million decreased $416 million or 36%, driven by:

•Unfavourable market-related impacts primarily reflecting interest rates and real estate experience(2);
•The prior year impact of the Canada Tax Rate Change(2); and
•Fair value changes in management's ownership of MFS shares; partially offset by
•The increase in underlying net income;
•The impact of the Bermuda Corporate Income Tax Change(2); and
•Lower DentaQuest integration costs.

Foreign exchange translation led to an increase of $2 million and $3 million in underlying net income and reported net income, respectively.

86 December 31, 2023 Sun Life Financial Inc. MANAGEMENT'S DISCUSSION & ANALYSIS The Q4'23 effective income tax rate (recovery)(1) on underlying net income and reported net income was 16.5% and (11.1)% respectively.


Our reported effective tax rate for the quarter represents a tax recovery. Declining interest rates led to higher tax-exempt investment income. We also recorded a $51 million tax recovery from establishing an economic transition deferred tax asset permitted under the new Bermuda Corporate Income Tax regime. These adjustments recorded in Q4'23 resulted in a net tax recovery.

Quarterly Comparison - Q4'23 vs. Q4'22
Asset Management
Asset Management underlying net income of $331 million increased $7 million or 2% driven by:
•MFS down $15 million (down US$11 million): Higher expenses offset by higher fee income from average net assets ("ANA"). The MFS pre-tax net operating profit margin(2) was 39% for Q4'23, compared to 40% in the prior year.
•SLC Management up $22 million: The increase in underlying net income was driven by higher fee-related earnings and higher net seed investment income. Fee-related earnings(2) increased 26% driven by higher AUM, reflecting strong capital raising and deployment across the platform and the AAM acquisition(3). Fee-related earnings margin(2) and pre-tax net operating profit margin(2) for Q4'23 were 24% and 22%, respectively (Q4'22 - 24% and 23%, respectively).

Asset Management reported net income of $297 million decreased $24 million or 7%, largely reflecting fair value changes in management's ownership of MFS shares.

Canada
Underlying net income of $350 million increased $85 million or 32%, reflecting:
•Wealth & asset management up $20 million: Increase in investment income driven by higher volume and yields.
•Group - Health & Protection up $57 million: Business premium growth and improved disability experience reflecting higher margins, lower claims volumes, and shorter claims durations.
•Individual - Protection up $8 million: Higher investment contributions partially offset by unfavourable mortality experience.
•Higher earnings on surplus, primarily driven by realized gains in the current year.

Reported net income of $348 million decreased $105 million or 23%, driven by market-related impacts primarily from interest rates and real estate experience, and the prior year impact of the Canada Tax Rate Change(4), partially offset by ACMA impacts and the increase in underlying net income.

(1)Our effective income tax rate on reported net income is calculated using Total income (loss) before income taxes, as detailed in Note 19 in our 2023 Annual Consolidated Financial Statements. Our effective income tax rate on underlying net income is calculated using pre-tax underlying net income, as detailed in section M - Non-IFRS Financial Measures in this document, and the associated income tax expense.
(2)Represents a non-IFRS financial measure. For more details, see section M - Non-IFRS Financial Measures in this document.
(3)On February 1, 2023, we completed the acquisition of a majority stake interest in Advisors Asset Management, Inc. ("the AAM acquisition"), a leading independent U.S. retail distribution firm, with the option to acquire the remaining interest starting in 2028.
(4)On December 15, 2022, legislation implementing an additional surtax of 1.5% applicable to banks and life insurer's taxable income in excess of $100 million was enacted in Canada ("Canada Tax Rate Change"). This legislation applied retroactively to the Federal Budget date of April 7, 2022. As a result, Canada reported net income increased by $90 million in Q4'22, reflected in Other adjustments.
                 MANAGEMENT'S DISCUSSION & ANALYSIS Sun Life Financial Inc. December 31, 2023 87


U.S.
Underlying net income of US$187 million increased US$14 million or 8%, driven by:
•Group - Health & Protection down US$7 million: Lower Dental results reflecting the impact of Medicaid redeterminations following the end of the Public Health Emergency, partially offset by higher Group Benefits results. In Group Benefits, strong revenue growth, higher net investment results and favourable mortality experience was partially offset by less favourable morbidity experience.
•Individual - Protection up US$21 million: The inclusion of the UK payout annuity business(1) and improved mortality experience.

Reported net income of US$77 million decreased US$74 million or 49%, driven by ACMA impacts, and market-related impacts largely from interest rates and real estate experience, partially offset by lower DentaQuest integration costs and the increase in underlying net income.

Asia
Underlying net income of $143 million increased $8 million or 6%, driven by:
•Individual - Protection up $20 million: Business growth reflecting good sales momentum, partially offset by lower earnings on surplus.
•Regional office expenses & other $(12) million increased net loss primarily reflecting continued pan Asia investments in the business.

Reported net income of $44 million decreased $48 million or 52%, driven by ACMA impacts, partially offset by the impact of the Bermuda Corporate Income Tax Change(2).

Corporate
Underlying net loss was $94 million compared to underlying net loss of $62 million in the prior year, driven by the sale of Sun Life UK(1) and higher operating expenses, partially offset by a lower effective tax rate.

Reported net loss was $41 million compared to $97 million reported net income in the prior year, reflecting the impacts from the sale of Sun Life UK (1), the prior year impact of tax-related matters(3), and the change in underlying net loss.


5. Fourth Quarter 2023 Growth
Revenue of $18.7 billion increased $10.2 billion compared to the same period in 2022, primarily reflecting fair value changes in invested assets driven by declining interest rates. Foreign exchange translation increased revenue by $30 million.





























(1)On April 3, 2023, we completed the sale of SLF of Canada UK Limited to Phoenix Group Holdings plc ("the sale of Sun Life UK"). Under the agreement, we will retain our economic interest in the payout annuities business through a reinsurance treaty, which, effective Q2'23 is recorded in In-force Management within the U.S. business group. For additional information, refer to Note 3 of our 2023 Annual Consolidated Financial Statements.
(2)On December 27, 2023, Bermuda enacted its Corporate Income Tax Act 2023, which will apply a 15% income tax beginning on January 1, 2025 ("Bermuda Corporate Income Tax Change"). The enacted legislation provides an economic transition adjustment that aligns an entity’s starting point for the tax regime more closely with its economic position prior to the application of the Corporate Income Tax 2023. The benefit of this economic transition adjustment has been recognized in 2023. As a result, reported net income increased by $51 million in the fourth quarter, reflected in Other adjustments.
(3)Tax related matters include tax-exempt investment income in reported net income in both years and the impact of the Canada Tax Rate Change. On December 15, 2022, legislation implementing an additional surtax of 1.5% applicable to banks and life insurer's taxable income in excess of $100 million was enacted in Canada ("Canada Tax Rate Change"). This legislation applied retroactively to the Federal Budget date of April 7, 2022. As a result, Corporate reported net income increased by $51 million in Q4'22, reflected in Other adjustments.

(2)Represents a non-IFRS financial measure. For more details, see section M - Non-IFRS Financial Measures in this document.

Third Quarter 2023
Underlying net income of $930 million decreased $19 million or 2%, driven by:
•Wealth & asset management up $38 million: Higher investment income driven by volume growth and an increase in yields, and higher Asset Management fee-related earnings.
•Group - Health & Protection up $4 million: Strong revenue growth across all U.S. businesses and better disability experience in Canada, largely offset by health and protection experience in the U.S., and lower fee-related earnings in Canada.
•Individual - Protection down $8 million: Lower earnings due to the sale of Sun Life UK, and lower net investment results in the U.S., partially offset by business growth reflecting good sales momentum during the past year in Asia.
•Corporate expenses & other $(53) million increase in net loss includes higher debt financing costs.
•Higher expenses across business types were driven by volume growth, continued investments in the business, and higher incentive compensation.

Reported net income of $871 million increased $760 million, driven by favourable market-related impacts primarily reflecting interest rates partially offset by real estate experience, a $170 million charge related to the sale of Sun Life UK and a higher increase in SLC Management's acquisition-related liabilities in the prior year, and ACMA impacts; partially offset by air value changes in management's ownership of MFS shares.

                 MANAGEMENT'S DISCUSSION & ANALYSIS Sun Life Financial Inc. December 31, 2023 89


Second Quarter 2023
Underlying net income of $920 million increased $112 million or 14%, driven by:
•Wealth & asset management down $1 million: Higher investment income driven by volume growth and an increase in yields was largely offset by lower fee-based earnings in MFS, reflecting equity market declines over the past year, as well as higher expenses in Canada.
•Group - Health & Protection up $122 million: Strong performance driven by good premium growth and better disability experience in Canada and the U.S., as well as a full quarter of DentaQuest contributions.
•Individual - Protection up $50 million: Higher premiums reflecting good sales momentum during the past year in Asia, and improved insurance experience in Canada and the U.S.
•Corporate expenses & other $(59) million increased net loss driven by higher operating expenses including incentive compensation and an increase in debt financing costs.
•Higher earnings on surplus reflecting an increase in realized gains and net interest income from higher rates.

Reported net income of $660 million decreased $270 million or 29%, driven by market-related impacts primarily reflecting interest rates and real estate investments, the prior year gain on the sale-leaseback of the Wellesley office in the U.S., and fair value changes in management's ownership of MFS shares; partially offset by the increase in underlying net income.

First Quarter 2023
Underlying net income of $895 million increased $175 million or 24%, driven by:
•Wealth & asset management down $11 million: Lower fee-based earnings in MFS, Canada, and Asia, reflecting equity market declines, largely offset by an increase in investment income driven by higher volumes and yields.
•Group - Health & Protection up $180 million: Strong performance including premium growth, improved disability in Canada and the U.S., strong medical stop-loss margins, and improved U.S. mortality. DentaQuest results also contributed to the increase.
•Individual - Protection up $42 million: Higher premiums reflecting good sales momentum during the past year, and improved mortality in Asia.
•Corporate Support & other $(36) million increased net loss: Higher operating expenses including long-term incentive compensation and IFRS 17 project spend, as well as an increase in debt financing costs.
•Higher investment income reflecting an increase in realized gains from surplus assets and net interest income from higher rates.

Reported net income of $806 million increased $141 million or 21%, driven by the increase in underlying net income and gain on the sale of the sponsored markets business in Canada, partially offset by market-related impacts, and DentaQuest integration and SLC Management acquisition-related costs.

Fourth Quarter 2022(1)
Reported net income of $951 million decreased $127 million or 12%, primarily reflecting unfavourable market-related impacts and DentaQuest integration costs, partially offset by the impact of the Canada Tax Rate Change, fair value changes on MFS' share-based payment awards and ACMA. Prior year reported net income included a gain on the initial public offering ("IPO") of our India asset management joint venture partially offset by an increase to SLC Management's acquisition-related liabilities. Underlying net income of $990 million increased $92 million or 10%, driven by business growth and experience in protection and health and contribution from the DentaQuest acquisition. This was partially offset by lower wealth and asset management earnings reflecting declines in global equity markets, and a higher effective tax rate compared to prior year.

Third Quarter 2022(1)
Reported    net income of $466 million decreased $553 million or 54% from prior year, primarily reflecting unfavourable market-related impacts, a $170 million charge related to the sale of Sun Life UK, less favourable ACMA impacts, and an increase in SLC Management's acquisition-related liabilities, partially offset by fair value changes on MFS' share-based payment awards. Underlying net income of $949 million increased $47 million or 5%, driven by business growth and experience in protection and health including a strong contribution from the DentaQuest acquisition. This was partially offset by lower fee-based income in wealth and asset management, mainly driven by declines in global equity markets.        

Second Quarter 2022(1)
Q2'22 reported net income of $785 million decreased $115 million or 13%, reflecting unfavourable market-related impacts and DentaQuest acquisition costs, partially offset by fair value changes on MFS' share-based payment awards and a gain on the sale-leaseback of our Wellesley office in the U.S. Underlying net income of $892 million was up slightly driven by business growth, new business gains, contribution from the DentaQuest acquisition, and lower incentive compensation expenses. This was largely offset by Asset Management results reflecting a decline in global equity markets driving lower average net assets, lower available-for-sale gains and morbidity experience in the U.S. Foreign exchange translation led to an increase of $16 million and $12 million in reported net income and underlying net income, respectively.

First Quarter 2022(1)
Q1'22 reported net income of $858 million decreased $79 million or 8%, driven by less favourable market-related impacts, partially offset by a Q1'21 restructuring charge and lower fair value changes on MFS' share-based payment awards. Underlying net income of $843 million was down slightly, driven by broad-based business growth, favourable expense experience and investment gains, offset by unfavourable mortality and morbidity experience, and lower AFS gains.

2. Underlying Net Income and Underlying EPS
Underlying net income is a non-IFRS financial measure that assists in understanding Sun Life's business performance by making certain adjustments to IFRS income. Underlying net income, along with common shareholders’ net income (Reported net income), is used as a basis for management planning, and is also a key measure in our employee incentive compensation programs. This measure reflects management's view of the underlying business performance of the company and long-term earnings potential. For example, due to the longer term nature of our individual protection businesses, market movements related to interest rates, equity markets and investment properties can have a significant impact on reported net income in the reporting period. However, these impacts are not necessarily realized, and may never be realized, if markets move in the opposite direction in subsequent periods or in the case of interest rates, the fixed income investment is held to maturity.

Effective January 1, 2023, we refined the definition of underlying net income as follows, and have updated prior period comparative figures to reflect these changes: (i) Market-related impacts was updated to reflect the adoption of IFRS 17 and IFRS 9; (ii) The adjustment for management’s ownership of MFS shares were updated to better reflect Sun Life’s interest in MFS’ earnings; and (iii) Removal of intangible asset amortization on acquired finite-life intangibles. Additional detail on these adjustments is provided below.

Underlying net income removes the impact of the following items from reported net income:
•Market-related impacts reflecting the after-tax difference in actual versus expected market movements, including:
i)Net interest impact from risk-free rate, credit spread, and swap spread movements, reflecting accounting mismatches between assets and liabilities:
a.Differences arising from fair value changes(1) of fixed income assets (including derivatives) measured at FVTPL supporting insurance contracts, compared to fair value changes of the liabilities(2);
b.Fair value changes of fixed income assets (including derivatives) measured at FVTPL supporting our investment contract liability and surplus portfolios(3); and
c.Tax-exempt investment income above or below expected long-term tax savings relating to our Canadian multi-national insurance operations.
ii)Non-fixed income investments where the weighted average expected return is approximately 2% per quarter, including:
a.Equity investments (including derivatives) supporting insurance contracts and surplus portfolios; and
b.Investment properties supporting insurance contracts and surplus portfolios.
•ACMA – captures the impact of method and assumption changes, and management actions on insurance and reinsurance contracts.
•Other adjustments:
i)Management’s ownership of MFS shares – this adjustment removes the change in fair value and other activity related to MFS common shares owned by management.
ii)Acquisition, integration, and restructuring - expense and income related to acquisition or disposal of a business. Also includes expenses related to restructuring activities.
iii)Intangible asset amortization - removes the amortization expense associated with finite life intangible assets arising from acquisitions or business combinations excluding amortization of software and distribution agreements.
iv)Other – represents items that are unusual or exceptional in nature which management believes are not representative of the long-term performance of the Company.

Underlying EPS (diluted). This measure is used in comparing the profitability across multiple periods and is calculated by dividing underlying net income by weighted average common shares outstanding for diluted EPS, excluding the dilutive impact of convertible instruments. For additional information about the underlying net income, see above. For additional information about the composition of the EPS, please refer to Note 25 of our 2023 Annual Consolidated Financial Statements for the period ended December 31, 2023. For additional information about the SLEECS, please refer to Note 12 of our 2023 Annual Consolidated Financial Statements.






















(1)For fixed income assets, Underlying Net Income includes credit experience from rating changes on assets measured at FVTPL, and the ECL impact for assets measured at FVOCI.
(2)Underlying net income is based on observable discount curves and exchange rates at the beginning of the period.
(3)Underlying net income for earnings on surplus includes realized gains (losses) on fixed income assets classified as FVOCI.

(3)Amounts relate to acquisition costs for our SLC Management affiliates, BentallGreenOak, InfraRed Capital Partners, Crescent Capital Group LP and Advisors Asset Management, Inc, which include the unwinding of the discount for Other financial liabilities of $86 million in 2023 ( 2022- $64 million).
(4)Reflects the changes in estimated future payments for acquisition-related contingent considerations and options to purchase remaining ownership interests of SLC Management affiliates of $42 million (2022 - $80 million).
(5)Includes acquisition and integration costs associated with DentaQuest, acquired on June 1, 2022.
(6)Includes a $65 million gain on the sale of the sponsored markets business in Canada in Q1'23 and a $19 million gain on the sale of Sun Life UK in Q2'23.
(7)Q3'22 reflects an impairment charge of $170 million pertaining to the attributed goodwill that was not expected to be recovered through the sale of Sun Life UK.
(8)Includes a charge of $48 million in Q3'22 reflecting the resolution of a matter related to reinsurance pricing for our U.S. In-force Management business, and Q2'22 reflects a gain on the sale-leaseback of the Wellesley office in the U.S.
(9)On December 15, 2022, legislation implementing an additional surtax of 1.5% applicable to banks and life insurer's taxable income in excess of $100 million was enacted in Canada ("Canada Tax Rate Change"). This legislation applied retroactively to the Federal Budget date of April 7, 2022. As a result, total Company reported net income increased by $141 million in Q4'22, reflected in Other adjustments.
(10)Q4'22 includes the unwinding of an internal reinsurance agreement.
(11)On December 27, 2023, Bermuda enacted its Corporate Income Tax Act 2023, which will apply a 15% income tax beginning on January 1, 2025 ("Bermuda Corporate Income Tax Change"). The enacted legislation provides an economic transition adjustment that aligns an entity’s starting point for the tax regime more closely with its economic position prior to the application of the Corporate Income Tax 2023. The benefit of this economic transition adjustment has been recognized in 2023. As a result, reported net income increased by $51 million in the fourth quarter, reflected in Other adjustments.

Taxes related to underlying net income adjustments may vary from the expected effective tax rate range reflecting the mix of business based on the Company's international operations and other tax-related adjustments.

3. Additional Non-IFRS Financial Measures
Management also uses the following non-IFRS financial measures:
After-tax profit margin for U.S. Group Benefits. This ratio expresses U.S. Group Benefits underlying net income as a percentage of net premiums. It assists in explaining our results from period to period and measures profitability. This ratio is calculated by dividing underlying net income (loss) by net premiums for the trailing four quarters. There is no directly comparable IFRS measure.

Assets under administration (in SLC Management). AUA represents Client assets for which Sun Life provides administrative services. In Asset Management, AUA includes assets distributed by SLC Management's affiliate, Advisors Asset Management, Inc. There is no directly comparable IFRS measure.

Assets under management. AUM is a non-IFRS financial measure that indicates the size of our Company's assets across asset management, wealth, and insurance. There is no standardized financial measure under IFRS. In addition to the most directly comparable IFRS measures, which are the balance of General funds and Segregated funds on our Statements of Financial Position, AUM also includes Third-party AUM and Consolidation adjustments. Effective January 1, 2023, "Other AUM" was renamed to "Third Party AUM", and "Consolidation adjustments" is presented separately as consolidation adjustments apply to all components of total AUM.

AUM not yet earning fees. This measure represents the committed uninvested capital portion of total AUM not currently earning management fees. The amount depends on the specific terms and conditions of each fund. There is no directly comparable IFRS measure.

Capital raising. This measure consists of increases in SLC Management's commitments from fund raising activities for all real estate, infrastructure and alternative credit Clients excluding leverage. Investment-grade fixed income capital raising consists of sales made to new Clients. There is no directly comparable IFRS measure.

Cash and other liquid assets. This measure is comprised of cash, cash equivalents, short-term investments, and publicly traded securities, net of loans related to acquisitions that are held at SLF Inc. (the ultimate parent company), and its wholly owned holding companies. This measure is a key consideration of available funds for capital re-deployment to support business growth.

We remove the impacts of foreign exchange translation from certain IFRS and non-IFRS measures to assist in comparing our results from period to period. The impacts of foreign exchange translation is approximated by using the foreign exchange rates in effect during the comparative period, using the average or period end foreign exchange rates, as appropriate.

CSM Movement Analysis includes certain non-IFRS financial measures, detailed below, and also presents certain measures on a net basis to reflect how management views the business, compared to a gross basis in the Consolidated Financial Statements. Examples include i) The impacts of insurance contracts issued is presented net of reinsurance; ii) Impact of new business is presented net of acquisition expense gain/loss; and iii) Certain methodology changes are presented as an impact of change in assumptions, whereas the Consolidated Financial Statement presentation is a contract modification.
•Organic CSM Movement is comprised of the Impact of new insurance business, Expected movements from asset returns & locked-in rates, Insurance experience gains/losses, and CSM recognized for services provided.
•Impact of new insurance business on CSM, also referred to as "new business CSM", represents growth from sales activity in the period, including individual protection sales (excluding joint ventures), and defined benefit solutions and segregated fund wealth sales in Canada. New business CSM is presented net of acquisition expense gain/loss.
•Expected movements from asset returns & locked-in rates applies to variable fee approach ("VFA") and general measurement approach ("GMA") contracts. For VFA contracts, this component of the CSM movement analysis is comprised of two factors: (i) the expected return on underlying assets and (ii) the measurement of financial guarantees. The difference between actual and expected results are reported as the impact of markets. For GMA contracts, this component of the CSM includes the accretion of the CSM balance at locked-in rates, which refer to the term structure associated with locked-in discount rates, set when the insurance contract was sold or on transition to IFRS 17. Average locked-in rates increase with the passage of time on in-force business and new business added at current rates.
•Impact of markets & other includes the difference between actual and expected movement for VFA contracts for: (i) the return on underlying assets and (ii) the measurement of financial guarantees. Also includes other amounts excluded from Organic CSM Movement.
•Insurance experience gains/losses represents the current period impacts of insurance experience, resulting in a change in future cash flows that adjust CSM.
•Impact of change in assumptions represents the future period impacts of changes in fulfilment cash flows that adjust CSM.
•CSM market sensitivities. CSM market sensitivities are non-IFRS financial measures for which there are no directly comparable measures under IFRS so it is not possible to provide a reconciliation of these amounts to the most directly comparable IFRS measures.

Deployment. This measure represents the amount of capital that has been invested in the period, including leverage where applicable. Deployment also includes capital committed in infrastructure deals to be invested in specific assets. There is no directly comparable IFRS measure.

Drivers of Earnings. The Drivers of Earnings ("DOE") analysis provides additional detail on the sources of earnings, primarily for protection and health businesses, and explains the actual results compared to the longer term expectations. The DOE is presented on a reported and underlying common shareholders' basis. Within the net insurance service result, the underlying DOE provides detail on expected insurance earnings, impact of new insurance business and experience gains (losses). Within the net investment result, the underlying DOE provides detail on expected investment earnings, credit experience, earnings on surplus, and joint ventures & other. For more information, refer to the headings "Underlying net income and Underlying EPS", "Earnings on surplus", "Notable items attributable to reported and underlying net income", in this document.

Certain amounts in the DOE are presented on a net basis to reflect how management views the business, compared to a gross basis in the Consolidated Financial Statements. Examples include: i) Net investment result and Other expenses of the Asset Management operating segment are combined with Fee Income to report the net contribution to earnings; ii) Income for fee-based businesses is reported net of the associated expenses; iii) Carried interest in SLC Management within Fee Income excludes the carried interest that Sun Life does not participate in economically, and nets the non-controlling interest portion of the carried interest against fee income and expenses of consolidated funds; iv) Net investment results include assets returns net of the crediting rate for investment contract liabilities and the unwinding of and changes in the discount rate for insurance contract liabilities; v) Earnings on surplus reflects net spread earned from investment strategies; vi) Earnings attributable to the participating account are excluded; and vii) Assumption changes and management actions combines the amounts included in Net insurance service result and Net investment result.

Earnings on Surplus. This component of the Drivers of Earnings represents the net income earned on a company’s surplus funds. Earnings on Surplus is comprised of realized gains on fair value through other comprehensive income assets, as well as net investment returns on surplus, such as investment income, gains (losses) on seed investments and investment properties mark-to-market, and also includes impacts from derivatives, currency and other items.

Experience-related items attributable to reported net income and underlying net income. These notable items attributable to reported net income and underlying net income are components of the Drivers of Earnings represents gains and losses that are due to differences between the actual results during the reporting period and management’s estimate of the expected longer-term returns on assets and liabilities (i.e. expected insurance earnings and expected investment earnings) at the start of the reporting period.

Fee earning AUM. FE AUM consists of assets managed by SLC Management, which are beneficially owned by Clients, on which we earn management fees for providing investment management, property management or advisory-related services. There is no directly comparable IFRS measure.

Fee-related earnings and Operating income. Fee-related earnings represent profitability of SLC Management's fee-related portfolios, and is calculated as Fee-related revenue less Fee-related expenses. Operating income represents profit realized from our business operations, and is calculated as the sum of Fee-related earnings, Investment income (loss) and performance fees, and Interest and other. Fee-related revenue represents all fee income, with the exception of performance fees, generated from third-party investors. Fee-related expenses represent all expenses directly related to generating fee revenue from third-party investors. Investment income (loss) and performance fees represent total income or loss from our seed investments, net of the related expenses. Interest and other represents performance fee compensation, our net interest income or expense and income from managing the General Account assets.

Fee-related earnings and Operating income are non-IFRS financial measures within SLC Management's Supplemental Income Statement, which enhances the comparability of SLC Management's results with publicly traded alternative asset managers. For more details, see our Supplementary Financial Information package for the quarter.

As such, we have excluded non-underlying market-related impacts as well as the gains or losses of certain non-seed hedges that are reported under Net investment income (loss) under IFRS. The reconciliation is as follows (amounts have been adjusted for rounding):
($ millions) 2023 2022

Financial leverage ratio. This ratio is an indicator of the Company's balance sheet strength measured by its proportion of capital qualifying debt in accordance with OSFI guidelines. This is calculated as the ratio of total debt plus preferred shares to total capital including the contractual service margin net of taxes, where debt consists of all capital-qualifying debt securities. Capital-qualifying debt securities consist of subordinated debt and innovative capital instruments. The CSM is included net of taxes because debts are repaid and serviced from available after-tax funds.

Effective January 1, 2023, the calculation for the financial leverage ratio was updated to include the CSM balance (net of taxes) in the denominator on adoption of IFRS 17 and IFRS 9.

Impacts of foreign exchange translation. To assist in comparing our results from period-to-period, the favourable or unfavourable impacts of foreign exchange translation are approximated using the foreign exchange rates, in effect during the comparative period, for several IFRS and Non-IFRS financial measures using the average or period end foreign exchange rates, as appropriate. Items impacting a reporting period, such as Revenue, Expenses, and Reported net income (loss) in our Consolidated Statements of Operations, as well as underlying net income (loss), and sales, are translated into Canadian dollars using average exchange rates for the appropriate daily, monthly, or quarterly period. For Assets and Liabilities in our Consolidated Statements of Financial Position, as well as the AUM and certain components of the Drivers of Earnings disclosure, period-end rates are used for currency translation purposes.

LICAT market sensitivities. LICAT market sensitivities are non-IFRS financial measures for which there are no directly comparable measures under IFRS so it is not possible to provide a reconciliation of these amounts to the most directly comparable IFRS measures.

Pre-tax fee related earnings margin. This ratio is a measure of SLC Management's profitability in relation to funds that earn recurring fee revenues, while excluding investment income and performance fees. The ratio is calculated by dividing fee-related earnings by fee-related revenues and is based on the last twelve months. There is no directly comparable IFRS measure.

Pre-tax net operating margin. This ratio is a measure of the profitability and there is no directly comparable IFRS measure. For MFS, this ratio is calculated by excluding management's ownership of MFS shares and certain commission expenses that are offsetting. These commission expenses are excluded in order to neutralize the impact these items have on the pre-tax net operating margin and have no impact on the profitability of MFS. For SLC Management, the ratio is calculated by dividing the total operating income by fee-related revenue plus investment Income (loss) and performance fees, and is based on the last twelve months.

96 December 31, 2023 Sun Life Financial Inc. MANAGEMENT'S DISCUSSION & ANALYSIS The following table provides a reconciliation to calculate MFS' pre-tax net operating margin:

(1)Other includes accounting basis differences, such as sub-advisory expenses and product allowances.
(2)Excluding non-controlling interest. For more information on Management's ownership of MFS shares, see the heading Underlying Net Income and Underlying EPS.

Return on equity. IFRS does not prescribe the calculation of ROE and therefore a comparable measure under IFRS is not available. To determine reported ROE and underlying ROE, respectively, reported net income (loss) and underlying net income (loss) is divided by the total weighted average common shareholders’ equity for the period. The ROE provides an indication of the overall profitability of the Company. The quarterly ROE is annualized.

Sales and flows. Asset Management gross flows includes funds from retail and institutional Clients; SLC Management gross flows include capital raising, such as uncalled capital commitments and fund leverage. Asset Management net flows consist of gross flows less gross outflows; SLC Management's net flows do not include Client distributions from the sale of underlying assets in closed-end funds. In Canada and in Asia, net sales consist of wealth sales & asset management gross flows less redemptions. In Canada, wealth sales & asset management gross flows consist of sales in Group Retirement Services and Individual Wealth; group - health & protection sales consist of workplace benefits sold by Sun Life Health; and individual - protection sales refer to individual insurance sales. In the U.S., group - health & protection sales consist of sales by Group Benefits and Dental. In Asia, wealth sales & asset management gross flows consist of Hong Kong wealth sales & asset management gross flows, Philippines mutual fund sales, wealth sales & asset management gross flows by our India and China joint ventures and associates, and Aditya Birla Sun Life AMC Limited's equity and fixed income mutual fund sales based on our proportionate equity interest, including sales as reported by our bank distribution partners; individual - protection sales consist of the individual insurance sales, by our subsidiaries and joint ventures and associates, based on our proportionate equity interest, in the Philippines, Indonesia, India, China, Malaysia, Vietnam, International, Hong Kong and Singapore. Asia also has group - health & protection sales in the Philippines, Hong Kong and our joint ventures. To provide greater comparability across reporting periods, we exclude the impacts of foreign exchange translation from sales and gross flows. There is no directly comparable IFRS measure.

Effective January 1, 2023, wealth sales & asset management gross flows in Group Retirement Services in Canada has been updated to exclude retained sales to better align with the methodology for LIMRA reporting. We have updated prior period amounts to reflect this change. Also effective January 1, 2023, insurance sales were renamed to "Group - Health & Protection sales" and "Individual - Protection sales" to better align to the business types within our business groups. For more information about business types, refer to section A - How We Report Our Results in this document.

Third-party AUM. Third-party AUM is composed of retail, institutional, and other third party assets, which includes general fund and segregated fund assets managed by our joint ventures. In Asset Management, third-party AUM includes Client assets for retail and institutional Clients, as well as capital raising, such as uncalled commitments and fund leverage in SLC Management. In Canada, third-party AUM includes Client assets in retail mutual fund products of Sun Life Global Investments. In Asia, third-party AUM includes Client assets in Hong Kong managed fund products, International wealth & asset management products, Philippines mutual and managed fund products, Aditya Birla Sun Life AMC Limited equity and fixed income mutual fund products, Sun Life Everbright Asset Management products and our joint ventures’ general fund and segregated fund assets based on our proportionate equity interest. There is no directly comparable IFRS financial measure.

Effective January 1, 2023, this measure was renamed to "third-party AUM", formerly "other AUM", in order to be more descriptive of the nature of these assets. Further, the presentation of "consolidation adjustments" has been updated in the current and prior periods to be shown separately from "third-party AUM", as consolidation adjustments apply to all components of total AUM.

Total weighted premium income ("TWPI"). This measure consists of 100% renewal premiums, 100% of first year premiums, and 10% of single premiums. In contrast to sales, which only includes premiums from new business, TWPI includes renewal premiums, reflecting the strength of the in-force block and providing a better understanding of both new and existing business. There is no directly comparable IFRS measure.

Underlying dividend payout ratio. This is the ratio of dividends paid per share to diluted underlying EPS for the period. The ratio is utilized during the medium-term capital budgeting process to inform our planned capital initiatives. We target an underlying dividend payout ratio of between 40% and 50% based on underlying EPS. For more information, see Section J - Capital and Liquidity Management in the 2023 Annual MD&A.

Underlying effective tax rate. This measure is calculated using the pre-tax underlying net income and the income tax expense associated with it. Our statutory tax rate is normally reduced by various tax benefits, such as lower taxes on income subject to tax in foreign jurisdictions, a range of tax-exempt investment income, and other sustainable tax benefits. Our effective tax rate helps in the analysis of the income tax impacts in the period.

100 December 31, 2023 Sun Life Financial Inc. MANAGEMENT'S DISCUSSION & ANALYSIS On January 1, 2023 we adopted IFRS 17 Insurance Contracts and IFRS 9 Financial Instruments, detailed below.


N. Accounting and Control Matters
We have also adopted several amended IFRS standards in the current year, which had no material impact on our Consolidated Financial Statements. For additional information, refer to Note 2 in our 2023 Annual Consolidated Financial Statements.

1. Critical Accounting Policies and Estimates
Our significant accounting and actuarial policies are described in Notes 1 and 6 of our 2023 Annual Consolidated Financial Statements. Management must make judgments involving assumptions and estimates, some of which may relate to matters that are inherently uncertain, under these policies. The estimates described below are considered particularly significant to understanding our financial performance. As part of our financial control and reporting, judgments involving assumptions and estimates are reviewed by the independent auditor and by other independent advisors on a periodic basis. Accounting policies requiring estimates are applied consistently in the determination of our financial results.

IFRS 17 and IFRS 9 require enhanced disclosures for insurance contracts and financial instruments. These disclosures are included primarily in Notes 5, 6, 10 and 22 of our Annual Consolidated Financial Statements for the period ended December 31, 2023. Certain disclosures in Note 2.B of the 2023 Annual Consolidated Financial Statements as well as the disclosures in this section of this document provide additional context during the first year of adoption of IFRS 17 and IFRS 9. The majority of these disclosures would otherwise only be reported by us annually.

1.A Insurance Contracts Summary and Methods and Assumptions
Summary
We sell a variety of insurance contracts that include many forms of life, health and critical illness insurance sold to individuals and groups, annuities, and segregated fund products with guarantees. We hold reinsurance contracts that transfer mortality and other risks following internal guidelines.

Insurance contracts with direct participation features are products where investments are managed on behalf of policyholders, and investment returns less a variable fee are passed through to policyholders with the insurance benefits they receive. Insurance contracts with direct participation features are measured using the VFA, and include segregated funds, unit-linked contracts, variable universal life contracts, and most participating insurance contracts. Reinsurance contracts (both issued and held) cannot be measured using the VFA.

Insurance contracts without direct participation features are eligible to use the PAA if the coverage period is one year or less, or if the result of applying the PAA is not expected to be a materially different result than applying the GMA in each reporting period over the life of the contract. Insurance contracts eligible to use the PAA include most group life and health contracts and the associated reinsurance contracts held.

Other insurance contracts are measured using the GMA. This includes most individual life and health insurance contracts and annuities and the associated reinsurance contracts held.

The Consolidated Statements of Financial Position present insurance contracts issued and reinsurance contracts held as both assets and liabilities, depending on whether the portfolio is in an asset or liability position.

For more information about insurance contracts issued and reinsurance contracts held, and Insurance contract liabilities for account of segregated fund holders, see Note 1, Note 10 and Note 21 of our 2023 Annual Consolidated Financial Statements.

Methods and Assumptions
General
A group of insurance contracts is measured as the total of FCF, which is the present value of future cash flows plus the risk adjustment for
non-financial risk, and, for groups measured using the GMA or VFA, the CSM. In measuring the present value of future cash flows, assumptions must be made about mortality and morbidity rates, lapse and other policyholder behaviour ("policyholder behaviour"), expenses and other factors over the life of our products, and the prevailing market view of the cost of financial risk in our products. Many of these assumptions relate to events that are anticipated to occur many years in the future. Assumptions require significant judgment and regular review and, where appropriate, revision.

The RA is the compensation we require for the uncertainty related to non-financial risk in the estimates of future cash flows. This compensation is measured by discounting cash flows from applying margins to the non-financial assumptions used in the estimate of future cash flows.

The CSM represents the unearned profit that will be recognized as insurance contract services are provided.

The methods and assumptions used in the measurement of insurance contracts are reviewed regularly and are subject to external actuarial peer review.

Present Value of Future Cash Flows
Assumptions for non-financial risk variables in the present value of future cash flows are intended to be current, neutral estimates of the expected outcome. The choice of assumptions takes into account current circumstances, past experience data from our own experience or from the industry, the relationship of past to expected future experience, anti-selection, the relationship among assumptions (including those for financial risk variables), and other relevant factors.
                 MANAGEMENT'S DISCUSSION & ANALYSIS Sun Life Financial Inc. December 31, 2023 101


Assumptions for financial risk variables in the present value of future cash flows are based on current observable market prices, adjusted to account for differences between the financial risk embedded in our products and those in the corresponding observed market instrument. Where no relevant market instrument is available, we use the best information available.

Mortality
Mortality refers to the rates at which death occurs for defined groups of people. Mortality assumptions are generally based on the past five to ten years of experience. Our experience is combined with industry experience or experience from reinsurers where our own experience is insufficient to be statistically valid. Assumed mortality rates for life insurance and annuity contracts include assumptions about future mortality improvement based on recent trends in population mortality and our outlook for future trends.

Morbidity
Morbidity refers to the rate of being unhealthy or disabled and the rates of recovery therefrom. Most of our disability insurance is marketed on a group basis. We offer critical illness policies on an individual basis in Canada and Asia, long-term care on an individual basis in Canada, and medical stop-loss insurance is offered on a group basis in the U.S. In Canada, group morbidity assumptions are based on our five-year average experience, modified to reflect any emerging trend in recovery rates. For Canadian long-term care and critical illness insurance in Canada and Asia, assumptions are developed in collaboration with our reinsurers and are largely based on their experience. In the U.S., our experience is used for both medical stop-loss and disability assumptions, with some consideration of industry or reinsurer experience.

Policyholder Behaviour
Lapse or surrender
Policyholders may allow their policies to lapse prior to the end of the contractual coverage period by choosing not to continue to pay premiums or by surrendering their policy for the cash surrender value. Assumptions for lapse or surrender experience on life insurance are generally based on our five-year average experience. Lapse or surrender rates vary by plan, age at issue, method of premium payment, policy duration and financial risk variables.

Premium payment patterns
For universal life contracts, it is necessary to set assumptions about premium payment patterns. Studies prepared by industry or the actuarial profession are used for products where our experience is insufficient to be statistically valid. Premium payment patterns usually vary by plan, age at issue, method of premium payment, policy duration and financial risk variables.

Expense
Future expenses directly attributable to the fulfilment of our insurance contracts include the costs of premium collection, claims adjudication and processing, actuarial calculations, preparation and mailing of policy statements, and related overhead. Future expense assumptions are mainly based on our recent experience using an internal expense allocation methodology. Inflationary increases assumed in future expenses are based on long-term expectations.

Acquisition expenses directly attributable to portfolios of insurance contracts include the costs of selling, underwriting and issuing insurance contracts. For new insurance contracts measured using the GMA or VFA, actual or estimated directly attributable acquisition expenses are recognized in the initial measurement of the contract. If estimates are used, the difference between estimated and actual acquisition expenses adjusts the CSM when the group of insurance contracts is closed to new contracts.

Current Discount Rates
Current discount rates are used to discount estimates of future cash flows in determining the present value of future cash flows. Current discount rates reflect the time value of money, the characteristics of the cash flows, and the liquidity characteristics of the insurance contracts.

Current discount rates for cash flows that do not vary based on returns on underlying items
Cash flows that do not vary at all based on the returns on any underlying items are discounted at rates that reflect the timing and currency of cash flows and the liquidity characteristics of the insurance contracts.

The timing of cash flows is reflected by constructing a discount curve, so that each cash flow is discounted consistent with the timing of the cash flow. In constructing the discount curve, a portion is based on market information (the observable period) and beyond that period, the discount rates are estimated (the unobservable period). The observable period, which varies by currency, is the time period where information on risk-free interest rates is deep and liquid. In the unobservable period, risk-free rates are interpolated between the last observable point and an ultimate risk-free rate at year 70. The ultimate risk-free rate is estimated using historical averages.

The currency of cash flows is reflected by using different discount curves for different currencies.

Liquidity is reflected by adding a liquidity premium to risk-free discount rates that is consistent with the liquidity characteristics of the insurance contracts. The liquidity premium in the observable period is based on the liquidity premium on assets with similar liquidity characteristics, which is estimated from the spread inherent in current market yields less a deduction for expected and unexpected credit losses. The deduction for expected and unexpected credit losses is estimated using historical rating agency data and current market conditions, and varies by asset type, quality, and duration. The liquidity premium in the unobservable period is interpolated between the last observable liquidity premium and an ultimate liquidity premium (at year 70) specific to liquid or illiquid contracts. See Note 10.A in the 2023 Annual Consolidated Financial Statements for further details, which provides a weighted average summary of the discount curves used to present value cash flows for all major products that do not vary based on the returns on underlying items.

Current discount rates for cash flows that vary with returns on underlying items
Discount rates for cash flows that vary directly with returns on underlying items reflect that variability. For the portion of cash flows that is a pass through of returns on underlying items to policyholders, the discount rate is such that the present value of cash flows equals the portion of the underlying items that is passed through to policyholders. For cash flows that vary, but not directly, with underlying items (e.g., financial
102 December 31, 2023 Sun Life Financial Inc. MANAGEMENT'S DISCUSSION & ANALYSIS guarantees), scenario testing may be necessary.


If so, discount rates used in the scenario projections are scenario-specific and based on the projected risk-free rates in the scenario plus liquidity premiums consistent with the liquidity characteristics of the contracts being measured.

Scenario Testing
Scenario testing may be required when the relationship between cash flows and financial risk variables is non-linear, or where there are complex interdependencies among cash flows. In scenario testing of financial risk variables, future cash flows are projected for each scenario path and discounted at the scenario-specific discount rates, resulting in a present value of future cash flows for each scenario. The provision for the projected cash flows is the average of the scenario-specific values. Assumptions for non-financial risk variables are the best estimate assumptions consistent with the scenario.

Scenarios are consistent with the current market environment. Our Economic Scenario Generator calibration process produces integrated stochastic scenarios of financial risk variables (e.g., risk-free interest rates, bond fund returns, equity returns) with parameters calibrated to replicate observable market prices of financial instruments available in the market. Adjustments are made when the insurance contracts being measured are illiquid but the financial instruments to which the scenarios are calibrated to are liquid.

Risk Adjustment for Non-Financial Risk
The RA for insurance contracts issued is the compensation we require for bearing uncertainty about the amount and timing of the cash flows that arises from non-financial risk. This amount is measured as the present value of the difference between estimated future cash flows with a margin applied to non-financial assumptions and estimated future cash flows without this adjustment. Margins generally range from 5% to 20% depending on the uncertainty in the determination of the assumption. The level of uncertainty, and hence the margin chosen, varies by assumption and by line of business and other factors. Considerations that would generally lead to a choice of margin at the higher end of the range are as follows:
•The statistical credibility of our experience is too low to be the primary source of data for choosing the assumption;
•Future experience is difficult to estimate;
•The cohort of risks lacks homogeneity;
•Operational risks adversely impact the ability to estimate the assumption; or
•Past experience may not be representative of future experience and the experience may deteriorate.

Margins are generally stable over time and are revised only to reflect changes in the level of uncertainty in the assumptions. Our margins tend to be at mid-range.

The RA for reinsurance contracts held represents the amount of risk transferred to the reinsurer. This is measured as the difference between the RA on the underlying insurance contracts without reinsurance and what the RA on the underlying insurance contracts would be with reinsurance. The RA for reinsurance contracts held increases the asset or reduces the liability for reinsurance contracts held.

The RA for insurance contracts issued and reinsurance contracts held corresponds to a confidence level of approximately 80-85% overall.

Contractual Service Margin
The initial and subsequent measurement of CSM is described in Note 2.A.i. in our 2023 Annual Consolidated Financial Statements. Additional detail about certain components of the measurement of CSM is provided below.

Interest accretion
For insurance contracts measured using the GMA, locked-in discount rates are used to accrete interest on the CSM. The locked-in discount rate for a group of insurance contracts is the weighted average of the current discount rates at initial recognition of the contracts in the group. For groups of contracts that are in-force as at transition (January 1, 2022), the locked-in discount rates are the discount rates in effect at the date of transition as the fair value approach was applied for these groups at transition.

For insurance contracts measured using the VFA, there is no accretion of interest. Rather, the CSM is adjusted by the change in our share of the fair value of underlying items.

Changes in FCF relating to future service
For insurance contracts measured using the GMA, locked-in discount rates are used to measure changes in FCF relating to future service. Changes in FCF relating to future service reflect changes in non-financial assumptions but not changes in assumptions related to financial risk.

For insurance contracts measured using the VFA, current discount rates are used to measure the change in FCF relating to future service. Changes in FCF relating to future service reflect both changes in non-financial assumptions and changes in assumptions related to financial risk.

Changes in FCF relating to future service include (Liability for Remaining Coverage only):
•All changes related to investment component payments (including current period payments);
•Changes arising from changes in assumptions used to derive the present value of future cash flows - limited to non-financial assumptions for insurance contracts measured using the GMA;
•Changes in future cash flows arising from claims in the current period; and
•For insurance contracts measured using the GMA, changes related to discretionary cash flows on some universal life and adjustable products. Discretionary cash flows are cash flows outside the guaranteed payments to the policyholder, and are described as a spread on earned rates (in the case of some universal life contracts) and in the policy on criteria for changes to adjustable policies for adjustable policies.

CSM recognized for services provided
The amount of CSM recognized as insurance revenue in each period to reflect the insurance contract services provided for a group of contracts in the period is determined by:
                 MANAGEMENT'S DISCUSSION & ANALYSIS Sun Life Financial Inc. December 31, 2023 103


•Identifying the total coverage units in the group (for services in current and future periods) – based on the quantity of insurance contract services;
•Allocating the CSM at the end of the period equally to each coverage unit in the current period and expected to be provided in the future (i.e., coverage units "unitize" the services provided); then
•Recognizing in insurance revenue the amount allocated to coverage units provided in the period.

Total coverage units for services expected to be provided in future periods is the present value of projected coverage units. The present value is measured using locked-in discount rates for groups measured using the GMA and current discount rates for groups measured using the VFA.

The coverage unit for a group is based on the nature of the insurance contract services provided. Insurance contract services comprise services for providing insurance coverage and, for some contracts, investment-return or investment-related services. It does not include services related to performing functions such as claims adjudication.

For insurance contracts measured using the VFA, coverage units are based on the policyholder's account value or the policyholders' share of the fair value of underlying items. For insurance contracts measured using the GMA, coverage units are based on the expected claim amount (excluding any investment component) for life and health insurance contracts, and the payment due in a period for annuity contracts.

For reinsurance contracts held, the amount of CSM recognized reflects the services received in the period.

Sensitivities to Insurance Methods and Assumptions
In addition to the insurance risks factors and risk management governance and controls described in section K - Risk Management in this document and the Risk Factors section of the 2023 AIF, we also note that on adoption of IFRS 17 and 9, the tables below include sensitivities of contractual service margins to insurance and other non-financial assumption risks.

The following table sets out the estimated immediate impact on, or sensitivity of, the CSM and net income to certain instantaneous changes in the insurance and other non-financial assumptions used in the calculation of our insurance contract liabilities, based on a starting point and business mix as at December 31, 2023 and December 31, 2022. These sensitivities are calculated independently for each risk factor, generally assuming that all other risk variables stay constant. The estimates are illustrative and different starting points for best estimate assumptions, CSM balances and business mix will result in different estimated sensitivities. These sensitivities represent the Company's estimate of changes in best estimate assumptions that are reasonably likely based on the Company's and/or the industry's historical experience and industry standards and best practices as at December 31, 2023 and December 31, 2022.

The impact on CSM is attributable to insurance contracts measured under the GMA and VFA. For insurance contracts measured under the GMA, the impact flows through the CSM at locked-in discount rates. For insurance contracts measured under the VFA, the impact flows through the CSM at current discount rates.

The impact on net income is attributable to any portion of the sensitivities for insurance contracts measured under the GMA and VFA that cannot be absorbed by CSM, the full impact for insurance contracts measured under the PAA, and the difference in impact between locked-in and current discount rates for insurance contracts measured under the GMA. If current discount rates are higher than locked-in rates, this generally results in a favourable impact to net income from contracts measured under the GMA.

The sensitivities exclude the impacts on the income from our joint ventures and associates, which we account for on an equity basis.

Fair Value of Assets and Liabilities
Debt securities, equity securities, most mortgages and loans and certain other invested assets are measured FVTPL or FVOCI and are recorded at fair value in our Consolidated Statements of Financial Position. Changes in fair value of assets measured FVTPL, and realized gains and losses on sale of FVTPL assets are recognized in income. Changes in fair value of FVOCI assets are recorded in OCI. For foreign currency translation, exchange differences calculated on the amortized cost of FVOCI assets are recognized in income and other changes in the carrying amount are recognized in OCI. Net impairment losses and realized gains and losses on sale of FVOCI assets (except for FVOCI equity securities as they remain in OCI) are reclassified from OCI to income.

The fair value of government and corporate debt securities is primarily determined using unadjusted quoted prices in active markets for identical or similar securities, where available. When quoted prices in active markets are not available, fair value is determined using market
104 December 31, 2023 Sun Life Financial Inc. MANAGEMENT'S DISCUSSION & ANALYSIS standard valuation methodologies, which include a discounted cash flow method, consensus pricing from various broker dealers that are typically the market makers, or other similar techniques.


The assumptions and valuation inputs in applying these market standard valuation methodologies are determined primarily using observable market inputs, which include, but are not limited to, benchmark yields, reported trades of identical or similar instruments, broker-dealer quotes, issuer spreads, bid prices, and reference data including market research publications. In limited circumstances, non-binding broker quotes are used.

The fair value of asset-backed securities is primarily determined using unadjusted quoted prices in active markets for identical or similar securities, where available, or valuation methodologies and valuation inputs similar to those used for government and corporate debt securities. Additional valuation inputs include structural characteristics of the securities, and the underlying collateral performance, such as prepayment speeds and delinquencies. Expected prepayment speeds are based primarily on those previously experienced in the market at projected future interest rate levels. In limited circumstances where there is a lack of sufficient observable market data to value the securities, non-binding broker quotes are used.

The fair value of equity securities is determined using unadjusted quoted prices in active markets for identical securities or similar securities. When quoted prices in active markets are not available, fair value is determined using equity valuation models, which include a discounted cash flow method and other techniques that involve benchmark comparison. Valuation inputs primarily include projected future operating cash flows and earnings, dividends, market discount rates, and earnings multiples of comparable companies. Where equity securities are less frequently traded, the most recent exchange-quoted pricing is used to determine fair value.

The fair value of mortgages and loans is determined by discounting the expected future contractual cash flows using a current market interest rate applicable to financial instruments with a similar yield, credit quality, and maturity characteristics. Valuation inputs typically include benchmark yields and risk-adjusted spreads from current internal lending activities or loan issuances. Beginning in the fourth quarter of 2022, valuation inputs also include external lending activities or loan issuances from both public and private markets, enhancing the market observability of inputs. The risk-adjusted spreads are determined based on the borrower’s credit and liquidity, as well as term and other loan-specific features.

The fair value of other financial liabilities is determined by using the discounted cash flow methodology at the incremental borrowing rate or the effective interest rate. Other financial liabilities categorized as Level 3 represent the present value of the estimated price we would pay to acquire any remaining outstanding shares upon exercise of a put option and any mandatory income distributions. The fair value of the liabilities is based on the average earnings before income tax, depreciation and amortization ("EBITDA") for the preceding years before the options’ exercise dates and EBITDA multiples in accordance with the put agreements as well as the expected amount of any mandatory income distributions. A change in EBITDA would impact the fair value of other financial liabilities and our net income (loss).

Derivative financial instruments are recorded at fair value with changes in fair value recorded in income unless the derivative is part of a qualifying hedging relationship for accounting purposes. The fair value of derivative financial instruments depends upon derivative types. The fair value of exchange-traded futures and options is determined using unadjusted quoted prices in active markets, while the fair value of OTC derivatives is determined using pricing models, such as a discounted cash flow method or other market standard valuation techniques, with primarily observable market inputs.

Valuation inputs used to price OTC derivatives may include swap interest rate curves, foreign exchange spot and forward rates, index prices, the value of underlying securities, projected dividends, volatility surfaces, and in limited circumstances, counterparty quotes.
The fair value of OTC derivative instruments also includes credit valuation adjustments to reflect the credit risk of both the derivative counterparty and ourselves as well as the impact of contractual factors designed to reduce our credit exposure, such as collateral and legal rights of offset under master netting agreements. Inputs into determining the appropriate credit valuation adjustments are typically obtained from publicly available information and include credit default swap spreads when available, credit spreads derived from specific bond yields, or published cumulative default experience data adjusted for current trends when credit default swap spreads are not available.

The fair value of other financial invested assets consists primarily of limited partnership investments which is based on net asset value ("NAV") provided by management of the limited partnership investments. Based on the unobservable nature of these NAVs, we do not assess whether applying reasonably possible alternative assumptions would have an impact on the fair value of the limited partnership investments.

Investment properties are recorded at fair value with changes in fair value recorded in income. The fair value of investment properties is generally determined using property valuation models that are based on expected capitalization rates and models that discount expected future net cash flows at current market interest rates reflective of the characteristics, location, and market of each property. Expected future net cash flows include contractual and projected cash flows and forecasted operating expenses, and take into account interest, rental and occupancy rates derived from market surveys. The estimates of future cash inflows, in addition to expected rental income from current leases, include projected income from future leases based on significant assumptions that are consistent with current market conditions. The future rental rates are estimated based on the location, type and quality of the properties, and take into account market data and projections at the valuation date. The fair values are typically compared to market-based information for reasonability, including recent transactions involving comparable assets. The methodologies and inputs used in these models are in accordance with real estate industry valuation standards. Valuations are prepared externally or internally by professionally accredited real estate appraisers.

Cash, cash equivalents and short-term securities are classified as held for trading for the purpose of meeting short-term cash requirements and accounted for at FVTPL due to their short-term nature or because they are frequently repriced to current market rates.

Investments for accounts of segregated fund holders are recorded at fair value with changes in fair value recorded in net realized and unrealized gains (losses) within the segregated fund and are not recorded in our Consolidated Statements of Operations. The fair value of investments for accounts of segregated fund holders is determined using unadjusted quoted prices in active markets or independent valuation information provided by investment managers. The fair value of direct investments within investments for accounts of segregated fund holders, such as short-term securities and government and corporate debt securities, is determined according to valuation methodologies and inputs described above in the respective asset type sections. The fair value of the secured borrowings from mortgage securitization is based on the methodologies and assumptions as described above for asset-backed securities.

                 MANAGEMENT'S DISCUSSION & ANALYSIS Sun Life Financial Inc. December 31, 2023 105


The fair value of investment contracts is measured through the use of prospective discounted cash flow method. For unit-linked contracts, the fair value is equal to the current unit fund value, plus additional non-unit liability amounts on a fair value basis if required. For non-unit-linked contracts, the fair value is equal to the present value of contractual cash flow. The fair value of the investment contract liabilities approximate their carrying values due to the nature of the contracts.

The fair values of these obligations are based on the fair value of the underlying securities, which can include debt or equity securities. The method used to determine fair value is based on the quoted market prices where available in an active market.

The fair value of underlying assets within our CLOs is determined primarily using observable market inputs, such as quoted prices for similar assets in active markets and other observable market data.

The fair value of underlying liabilities within our CLOs is determined by discounting expected future contractual cash flows using a current market interest rate applicable to financial instruments with a similar yield, credit quality, maturity characteristics, and structural credit protections. The valuation technique maximizes the use of observable inputs that incorporates comparable securities’ prices and other market intelligence.

The methodologies and assumptions for determining the fair values of investment contract liabilities are included in Note 10.A of the 2023 Annual Consolidated Financial Statements.

We categorize our assets and liabilities carried at fair value, based on the priority of the inputs to the valuation techniques used to measure fair value, into a three-level fair value hierarchy as follows:

Level 1: Fair value is based on the unadjusted quoted prices for identical assets or liabilities in an active market. The types of assets and liabilities classified as Level 1 generally include cash and cash equivalents, certain U.S. government and agency securities, exchange-traded equity securities, and certain segregated and mutual fund units held for account of segregated fund holders.

Level 2: Fair value is based on quoted prices for similar assets or liabilities traded in active markets, or prices from valuation techniques that use significant observable inputs, or inputs that are derived principally from or corroborated with observable market data through correlation or other means. The types of assets and liabilities classified as Level 2 generally include Canadian federal, provincial and municipal government, other foreign government and corporate debt securities, certain asset-backed securities, OTC derivatives, and certain segregated and mutual fund units held for account of segregated fund holders.

Level 3: Fair value is based on valuation techniques that require one or more significant inputs that are not based on observable market inputs. These unobservable inputs reflect our expectations about the assumptions market participants would use in pricing the asset or liability. The types of assets and liabilities classified as Level 3 generally include certain corporate bonds, certain other invested assets, and investment properties.

As pricing inputs become more or less observable, assets are transferred between levels in the hierarchy. Total gains and losses in income and OCI are calculated assuming transfers into or out of Level 3 occur at the beginning of the period. For a financial instrument that transfers into Level 3 during the reporting period, the entire change in fair value for the period is included in the Level 3 reconciliation schedule in Note 5 of our 2023 Annual Consolidated Financial Statements. For transfers out of Level 3 during the reporting period, the change in fair value for the period is excluded from the Level 3 reconciliation schedule in Note 5 of our 2023 Annual Consolidated Financial Statements. Transfers into Level 3 occur when the inputs used to price the financial instrument lack observable market data and as a result, no longer meet the Level 1 or 2 criteria at the reporting date. Transfers out of Level 3 occur when the pricing inputs become more transparent and satisfy the Level 1 or 2 criteria at the reporting date.

Transfers into and out of Level 3 for financial assets were $390 million and $918 million for the year ended December 31, 2023, respectively, (December 31, 2022 - $nil(1) and $123 million(1), respectively). The total amount of the net realized/unrealized gains (losses) related to financial instruments transferred out of Level 3 during the period, which were excluded from the Level 3 reconciliation, was a gain of $31 million as at December 31, 2023 (December 31, 2022 - loss of $18 million(1)).

Additional information on the fair value measurement of investments can be found in Note 5 of our 2023 Annual Consolidated Financial Statements.

Goodwill
Goodwill represents the excess of the cost of an acquisition over the fair value of the net identifiable tangible and intangible assets of the acquired businesses. Goodwill is carried at original cost less any impairment subsequently incurred. Goodwill is assessed for impairment annually or more frequently if events or circumstances occur that may result in the recoverable amount of a cash generating unit ("CGU") falling below its carrying value. A CGU is the smallest identifiable group of assets that generates cash inflows that are largely independent of cash inflows from other groups of assets. The goodwill balances are allocated to either individual or groups of CGUs that are expected to benefit from the synergies of the business combination. Goodwill impairment is quantified by comparing a CGU's or a group of CGU's carrying value to its recoverable amount, which is the higher of fair value less cost to sell and value in use. Impairment losses are recognized immediately and cannot be reversed in future periods.

Impairment charges on goodwill of $nil were recognized in 2023. We had a carrying value of $8,969 million in goodwill as at December 31, 2023. Additional information on goodwill can be found in Note 9 of our 2023 Annual Consolidated Financial Statements.

106 December 31, 2023 Sun Life Financial Inc. MANAGEMENT'S DISCUSSION & ANALYSIS Intangible assets consist of finite life and indefinite life intangible assets.


Intangible Assets
Finite life intangible assets are amortized on a straight-line basis or using a units-of-production method, over the useful economic lives: i) Distribution, sales potential of field force, client relationships and asset administration contracts - 3 to 40 years ii) and internally generated software - 3 to 10 years. Amortization is charged through operating expenses. The useful lives of finite life intangible assets are reviewed annually, and the amortization is adjusted as necessary. Indefinite life intangibles are not amortized, and are assessed for impairment annually or more frequently if events or changes in circumstances indicate that the asset may be impaired. Impairment is assessed by comparing the carrying values of the indefinite life intangible assets to their recoverable amounts. The recoverable amount is the higher of an asset's fair value less costs to sell and its value in use. If the carrying values of the indefinite life intangibles exceed their recoverable amounts, these assets are considered impaired, and a charge for impairment is recognized in our Consolidated Statements of Operations. The recoverable amount of intangible assets is determined using various valuation models, which require management to make certain judgments and assumptions that could affect the estimates of the recoverable amount. Impairment charges on intangible assets of $5 million were recognized in 2023 (2022 - $18 million).

As at December 31, 2023, our finite life intangible assets had a carrying value of $4 billion, which reflected the value of the field force, asset administration contracts, and Client relationships acquired as part of the Clarica, CMG Asia, Genworth EBG, Dialogue, Ryan Labs, Prime Advisors, AAM, Bentall Kennedy, DentaQuest and the U.S. employee benefits business acquisitions, the ACB bancassurance partnership, and Crescent, as well as software costs. Our indefinite life intangible assets had a carrying value of $1 billion as at December 31, 2023. The value of the indefinite life intangible assets reflected fund management contracts of MFS, BGO, InfraRed, Crescent and AAM.

Income Taxes
Income tax assets and liabilities for the current and prior periods are measured at the amount expected to be recovered from or paid to the taxation authorities. Deferred income tax is provided using the liability method. Our provision for income taxes is calculated based on the tax rates and tax laws that have been enacted or substantially enacted by the end of the reporting period.

As a multinational organization, we are subject to taxation in numerous jurisdictions. We seek to operate in a tax efficient manner while ensuring that we are in compliance with all laws and regulations. The determination of the required provision for current and deferred income taxes requires that we interpret tax legislation in the jurisdictions in which we operate and that we make assumptions about the expected timing of realization of deferred income tax assets and liabilities. Tax laws are complex and their interpretation requires significant judgment. The provision for income taxes reflects management's interpretation of the relevant tax laws and its best estimate of the income tax implications of the transactions and events during the period. We believe that our provisions for uncertain tax positions appropriately reflect the risk of tax positions that are under audit, dispute or appeal with tax authorities, or which are otherwise considered to involve uncertainty. The adequacy of our tax provision is reviewed at the end of each reporting period. To the extent that our interpretations differ from those of tax authorities or the timing of realization is not as expected, the provision for income taxes may increase or decrease in future periods to reflect actual experience. The amount of any increase or decrease cannot be reasonably estimated.

Deferred income tax assets are recognized for all deductible temporary differences, carry forward of unused tax losses and unused tax credits to the extent that it is probable that taxable profit will be available against which the temporary differences, unused tax losses and unused tax credits can be utilized. At each reporting period, we assess all available evidence, both positive and negative, to determine the amount of deferred income tax assets to be recorded. If it is probable that the benefit of tax losses and tax deductions will not be realized, a deferred income tax asset is not recognized. The assessment requires significant estimates and judgment about future events based on the information available at the reporting date.

From time to time, local governments, in countries in which we operate, enact changes to statutory corporate income tax rates. These changes require us to review and re-measure our deferred tax assets and liabilities as of the date of enactment. As at December 31, 2023, our net deferred tax asset in the Consolidated Statements of Financial Position was $3,597 million, primarily in Canada. Any future tax rate reductions in jurisdictions where we carry a net deferred tax asset, could result in a reduction in the carrying value of the deferred tax asset and a corresponding income tax expense at the time of substantial enactment of a rate reduction.

The Organisation for Economic Co-operation and Development’s (OECD’s) base erosion and profit shifting (BEPS) project has prompted governments around the world, including Canada, to consider wide-ranging tax reforms to address BEPS and transparency issues. The proposals include introducing a global minimum tax rate of 15% to ensure that large multinational enterprises pay a minimum level of tax on the income arising in each jurisdiction where they operate.

On August 4, 2023, the Canadian Department of Finance released draft legislation to implement certain previously announced measures, including application rules for a 15% global minimum tax under Pillar Two, which is applied on a jurisdiction-by-jurisdiction basis. The global minimum tax rules will apply to Sun Life effective January 1, 2024, however the timing of the substantive enactment of these rules in most jurisdictions where Sun Life operates is uncertain. Under the legislation, Sun Life is liable to pay a top-up tax for the difference between the effective tax rate under the Pillar Two rules on a jurisdiction-by-jurisdiction basis, and the 15% minimum rate. The Pillar Two rules are not expected to have a material impact on Sun Life’s consolidated financial statements when they become effective.

On December 27, 2023, Bermuda enacted its Corporate Income Tax Act 2023, which will apply a 15% income tax beginning on January 1, 2025. Bermuda Corporate Income Taxes are expected to be a covered tax and will reduce Pillar Two top-up taxes which would otherwise be payable to other jurisdictions. The enacted legislation provides an economic transition adjustment that aligns an entity’s starting point for the tax regime more closely with its economic position prior to the application of the Corporate Income Tax 2023. The benefit of this economic transition adjustment has been recognized in 2023. The Bermuda Corporate Income Tax is not expected to have a material impact on Sun Life’s consolidated financial statements when it becomes effective in 2025.

The Canadian Department of Finance has issued legislation which, if enacted, may limit the deductibility of interest and financing expenses for Canadian tax purposes, and would apply to Sun Life effective January 1, 2024. A Notice of Ways and Means Motion, which included this legislation, was released and tabled in Parliament in November 2023. We continue to monitor developments and assess the impact on our consolidated financial statements.

Pension Plans and Other Post-Retirement Benefits
The Company sponsors defined benefit pension plans and defined contribution plans for eligible employees. All of our material defined benefit plans worldwide are closed to new entrants with new hires participating in defined contribution plans. Our defined benefit pension plans offer benefits based on length of service and final average earnings and certain plans offer some indexation of benefits. We maintain certain supplementary non-contributory defined benefit pension arrangements for eligible employees, which are primarily for benefits which are in excess of local tax limits. In addition to these plans, in some countries the Company sponsors certain post-retirement benefit plans (for medical, dental and/or life insurance benefits) for eligible qualifying employees and their dependents who meet certain requirements.

In Canada, since January 1, 2009, all new employees participate in a defined contribution plan, while existing employees continue to accrue future benefits in the prior plan which provides a defined benefit plan and an optional contributory defined contribution plan.

With the closure of the Canadian defined benefit plans to new entrants, the volatility associated with future service accruals for active members has been limited and will decline over time. As at December 31, 2023, there are no active employees accruing future service benefits in the U.S. defined benefit plans. In 2023 all assets and liabilities associated with the UK pension plans were transferred to the buyer as part of the sale of Sun Life's UK business.

The major risks remaining in relation to past service obligations are increases in liabilities due to a decline in discount rates, greater life expectancy than assumed and adverse asset returns. We have significantly de-risked the investments of our material defined benefit pension plans Company-wide by systematically shifting the pension asset mix towards liability matching investments. The target for our significant plans is to minimize volatility in funded status arising from changes in discount rates and exposure to equity markets.

Due to the long-term nature of these defined benefit plans, the calculation of benefit expenses and accrued benefit obligations depends on various assumptions, including discount rates, rates of compensation increases, health care cost trend rates, retirement ages, mortality rates and termination rates. Based upon consultation with external pension actuaries, management determines the assumptions used for these plans on an annual basis. The discount rate used for our material defined benefit plans is determined with reference to market yields of high-quality corporate bonds that are denominated in the same currency in which the benefits will be paid, and that have terms to maturity approximating the terms of obligations.

Actual experience may differ from that assumed, which would impact the valuation of defined benefit plans and the level of benefit expenses recognized in future years. Details of our pension and post-retirement benefit plans and the key assumptions used for the valuation these plans are included in Note 24 of our 2023 Annual Consolidated Financial Statements.

2. Changes in Accounting Policies
We have included in this section a summary of changes in accounting policies. Where there are references to Notes, these are part of our 2023 Annual Consolidated Financial Statements. Please also refer to Note 2 of our Annual Consolidated Financial Statements for more details.

2.A New and Amended International Financial Reporting Standards Adopted in 2023

2.A.i Adoption of IFRS 17 Insurance Contracts and IFRS 9 Financial Instruments
In May 2017, the IASB issued IFRS 17 Insurance Contracts ("IFRS 17"), with an amendment issued in June 2020 to defer the effective date of IFRS 17 to annual periods beginning on or after January 1, 2023. This standard is to be applied using a retrospective approach, with at least one year of comparative results provided. If retrospective application to a group of insurance contracts is impracticable, a modified retrospective or fair value approach may be used. IFRS 17 replaces IFRS 4 Insurance Contracts ("IFRS 4") and impacts how we recognize, measure, present, and disclose our insurance contracts in our Consolidated Financial Statements.

IFRS 17 and IFRS 9 Financial Instruments ("IFRS 9") were effective for us beginning January 1, 2023. IFRS 9 includes guidance on the classification and measurement of financial instruments, impairment of financial assets and hedge accounting, and does not require restatement of comparative periods. IFRS 9 replaces IAS 39 Financial Instruments: Recognition and Measurement ("IAS 39"). We are permitted, under IFRS 17, to present comparative information on financial assets as if IFRS 9 were applicable during the comparative period ("classification overlay"). We have elected to apply the classification overlay to our financial assets and their comparative period results as if IFRS 9 had been effective since January 1, 2022. Certain comparative period information will continue to be presented in accordance with our previous accounting policies.

For initial measurement of insurance contracts at the transition date of January 1, 2022, we have elected to use the fair value approach for all groups for which the retrospective approach is impracticable. For more information on the application of the fair value approach at transition, see the heading "Fair Value Measurement" in Note 2.A.i in our 2023 Annual Consolidated Financial Statements.

IFRS 17 establishes principles for the recognition, measurement, presentation, and disclosure of insurance contracts. The key principles of IFRS 17 are as follows:
•Insurance contracts are those under which an entity accepts significant insurance risk from another party ("policyholder") by agreeing to compensate the policyholder if a specified uncertain future event ("insured event") adversely affects the policyholder.
•Insurance contracts issued and reinsurance contracts held are divided into groups that will be separately recognized and measured.
•Groups of insurance contracts are recognized and measured as the total of the following measurement components: a) the present value of future cash flows; b) a risk adjustment for non-financial risk ("RA"); and c) the Contractual Service Margin ("CSM"), an amount that represents the unearned profit of the group of contracts. These measurement components apply to groups of insurance contracts measured using the GMA and the VFA. The VFA applies to insurance contracts issued with direct participation features, which are substantially investment-related service contracts under which the policyholder is promised an investment return based on underlying items, such as segregated funds and certain participating insurance contracts. For short duration contracts, such as most of our group life and health business, a simplified measurement approach (PAA) is applied. Under the PAA, insurance contracts are measured based on unearned profits and do not include a CSM.
108 December 31, 2023 Sun Life Financial Inc.      MANAGEMENT'S DISCUSSION & ANALYSIS         


•The profit from a group of insurance contracts is recognized into income over the period that insurance contract services are provided and as the non-financial risks related to providing the insurance contracts diminish.
•Insurance revenue, insurance service expenses and insurance finance income or expenses are presented separately.

Significant Differences between IFRS 17 and IFRS 4
The following section describes the most significant differences between IFRS 17 and the accounting policies applied under IFRS 4.

Scope
There is no substantial change in IFRS 17 compared to IFRS 4 with regards to which contracts fall within the scope of the standard. However, we have updated the accounting policy for classification that was adopted on the transition to IFRS 4 in 2011 to ensure consistency with the IFRS 17 definition of insurance contracts.

Under IFRS 17, an insurance contract is defined as a contract under which the issuer accepts significant insurance risk from the policyholder by agreeing to compensate the policyholder if an insured event adversely affects the policyholder. In assessing whether "significant" insurance risk exists, certain contracts that were classified as insurance contracts under IFRS 4 were reclassified as investment contracts under IFRS 17. Such changes in classification were limited to certain deferred annuity products where the insurance risk is limited to the right to annuitize the maturity benefit, which fell short of the threshold for "significant" insurance risk.

Furthermore, IFRS 17 includes new requirements for the separation of distinct investment components and distinct goods or non-insurance service components of insurance contracts. At transition to IFRS 17, there were no distinct investment components and only immaterial distinct service components in our insurance contracts.

Unlike IFRS 4, IFRS 17 requires reinsurance contracts held to be measured separately from the underlying direct contracts. A reinsurance contract is an insurance contract issued by the reinsurer to compensate another entity for claims arising from one or more insurance contracts issued by that other entity ("underlying contracts").

Only contracts that transfer insurance risk to the reinsurer are considered reinsurance contracts held from the ceding entity’s point of view. We have reinsurance treaties that transfer only non-insurance risks to the reinsurer, however these are not considered reinsurance contracts held in scope of IFRS 17, nor were they in scope of IFRS 4. Rather, they are treated as insurance contracts purchased.

Reinsurance treaties that are part of the underlying items of participating insurance contracts (i.e., where all the cash flows of the reinsurance treaty are fully passed through to the participating insurance policyholders) are measured and reported separately.

Investment contracts with DPF are in scope of IFRS 17 and were in scope of IFRS 4. However, such contracts were reported with other investment contracts under IFRS 4, and are reported with insurance contracts under IFRS 17.

Measurement
The measurement of insurance contracts under IFRS 17 differs from the Canadian Asset Liability Method previously applied under IFRS 4. The most significant differences by measurement component are as follows:

Present value of future cash flows:
•The discount rates used to present value future cash flows under IFRS 17 are based on the characteristics of the insurance contracts. Under IFRS 4, the Canadian Asset Liability Method is used to determine actuarial liabilities based on the portfolio of assets currently supporting the insurance contract liabilities and reinvestment assumptions.
•Estimates under IFRS 17 include the current market view of the cost of financial guarantees, which requires a valuation consistent with market option prices. Under IFRS 4, the cost of financial guarantees is based on the amount required to fulfill the obligation but not directly linked to market option prices.
•Expense cash flows under IFRS 17 are limited to those directly attributable to fulfillment of the obligations under insurance contracts.
•Future income taxes are excluded from future cash flows under IFRS 17.

Risk adjustment for non-financial risk:
•Measures the compensation required for uncertainty related to non-financial risk, such as mortality, morbidity, surrender and expenses under IFRS 17.
•Provisions for uncertainty related to financial risk are implicitly included in the present value of future cash flows under IFRS 17.
•No amount is provided for asset-liability mismatch risk under IFRS 17.
•Under IFRS 4, amounts provided for the risks listed above are reflected in a provision for adverse deviations included in insurance contract liabilities.

CSM:
•This is a new component of liabilities and necessitates the "grouping" of insurance contracts, which is not required under IFRS 4.
•The CSM represents unearned profits, as discussed above.

The measurement approaches under IFRS 17 and IFRS 4 are similar for insurance contracts measured using the PAA, such as our group life and health contracts. Differences arise mainly in the measurement of the liability for incurred claims ("LIC"), where the discount rate and risk adjustment for non-financial risk changes noted above apply.

Presentation
IFRS 17 requires that portfolios of insurance contracts that are in an asset position be presented separately from portfolios of insurance contracts that are in a liability position in the Consolidated Statements of Financial Position. Also, portfolios of insurance contracts issued must be presented separately from portfolios of reinsurance contracts held. Previously, insurance contracts issued were presented only as liabilities and reinsurance contracts held were presented only as assets. Certain balances, such as policy loans and outstanding and prepaid
                 MANAGEMENT'S DISCUSSION & ANALYSIS Sun Life Financial Inc. December 31, 2023 109


premiums, that were previously presented separately or included in Other assets and Other liabilities are now included in the assets or liabilities for insurance contracts issued or reinsurance contracts held.

The presentation of income from insurance contracts on the Consolidated Statements of Operations has changed significantly for IFRS 17. Prior to IFRS 17, insurance related income was presented separately in the lines Gross premiums, Ceded premiums, Gross claims and benefits paid, Reinsurance expenses (recoveries), Increase (decrease) in insurance contract liabilities, and Decrease (increase) in reinsurance assets. The line Operating expenses, commissions and premium taxes included all expenses, reflecting those from both insurance and non-insurance contracts.

Under IFRS 17, insurance-related income is presented in the Insurance service result section and the Insurance finance income (expenses) line in the Investment result section. Amounts are presented separately for insurance contracts issued and reinsurance contracts held. The Insurance service expenses line includes amounts previously reported as Gross claims and benefits paid, with the exclusion of repayments of investment components, which are amounts that are returned to policyholders under all circumstances. Directly attributable expenses are also presented as Insurance service expenses. Income or expense from reinsurance contracts held is now presented as one line, which includes an allocation of reinsurance premiums paid and amounts recovered from reinsurers.

For insurance contracts measured using the GMA or VFA, premiums are no longer reported as revenue or recognized in income when received. Insurance revenue in a reporting period is comprised of the portion of premiums that cover expected claims and directly attributable expenses in the period, as well as the release of RA and the amortization of CSM for the period. Insurance revenue excludes the portion of premiums that cover repayment of investment components.

Fee income excludes income from insurance contracts as any fees earned would be recognized in Insurance contract revenue. Similarly, the Operating expenses and commissions line excludes expenses that are directly attributable to issuing or fulfilling insurance contracts as these expenses, as well as premium taxes paid, are included in the Insurance service result section.

Revised accounting policies on adoption of IFRS 17
For more information about the revised accounting policies as a result of the adoption of IFRS 17 that differ from those included in our 2022 Annual Consolidated Financial Statements, refer to Note 2.A.i of our 2023 Annual Consolidated Financial Statements.

Impacts on our financial performance
We have highlighted in the following section certain impacts on our financial performance as a result of the differences between IFRS 17 and IFRS 4 described above:
•New business gains (unearned profits) are measured differently under IFRS 17, reflecting measurement differences on insurance contracts as discussed above. In addition, new business gains under IFRS 17 are deferred and recorded in the CSM and amortized into income as insurance contract services are provided. Losses on new business are also measured differently, but continue to be recognized in income immediately. Under IFRS 4, new business gains and losses were both recognized in income immediately.
•Discount rates used in calculating the present value of insurance contract liabilities are based on the characteristics of the insurance contracts rather than the assets supporting the liabilities. Amongst other differences, this results in changes in the timing of when investment-related income emerges.
•Under IFRS 17, changes related to financial risk (e.g. changes in the discount rate) continue to be recognized in income immediately, except for insurance contracts measured using the VFA, where the changes are recorded through the CSM. Assumption changes for non-financial risk, such as mortality, are reflected in the CSM and amortized into income as insurance contract services are provided. Under IFRS 4, assumption changes for both financial and non-financial risk variables were recognized in income immediately.

Significant Differences between IFRS 9 and IAS 39
The following section describes the most significant differences between IFRS 9 and the accounting policies applied under IAS 39.

Classification of financial assets and financial liabilities
IFRS 9 introduces three principal classification categories for financial assets. Financial assets are measured at initial recognition at fair value, and are classified as and subsequently measured at FVTPL, FVOCI or amortized cost based on our business model for managing the financial asset and the contractual cash flow characteristics of the asset.

IFRS 9 eliminates the previous IAS 39 categories of held-to-maturity, available-for-sale ("AFS"), and loans and receivable financial assets. Under IFRS 9, derivatives embedded in contracts where the host is a financial asset in scope of IFRS 9 are not separated. Instead, the hybrid financial instrument, as a whole, is assessed for classification.

IFRS 9 maintains the IAS 39 classification for financial liabilities. Under IFRS 9, financial liabilities are measured at either amortized cost or FVTPL.

Under IFRS 17, we elected to recognize all insurance finance income or expense in income rather than other comprehensive income. Consequently, to avoid an accounting mismatch, we are electing under IFRS 9 to classify most of our fixed income assets supporting insurance contracts as FVTPL.

Impairment of financial assets
IFRS 9 replaces the "incurred loss" model under IAS 39 with a forward-looking ECL model. The new impairment model applies to financial assets measured at amortized cost, debt securities measured at FVOCI, mortgages and loans measured at FVOCI, lease receivables, account receivables, loan commitments and financial guarantees not measured at FVTPL. Credit losses are recognized earlier under IFRS 9 as compared previously under IAS 39. IFRS 9 introduces an impairment model for financial assets not measured at FVTPL. The model requires the recognition of an allowance for 12-month expected losses at the initial recognition of a financial asset, and the recognition of an allowance for lifetime expected losses if certain criteria are met.
110 December 31, 2023 Sun Life Financial Inc. MANAGEMENT'S DISCUSSION & ANALYSIS In August 2020, the IASB issued the Interest Rate Benchmark Reform Phase 2, which includes amendments to IFRS 9, IAS 39, IFRS 7 Financial Instruments: Disclosures ("IFRS 7"), IFRS 4, and IFRS 16 Leases ("IFRS 16").


Hedge accounting
IFRS 9 introduced a new hedge accounting model, but permits entities to continue applying hedge accounting requirements under IAS 39 instead of those under IFRS 9. We have elected to continue applying the hedge accounting requirements under IAS 39.
Interest Rate Benchmark Reform - Phase 2 amendments
These amendments address issues that arise from the implementation of the reforms, including the replacement of a benchmark with an alternative reference rate (“ARR”), such as the Secured Overnight Financing Rate (“SOFR”), in the case of US dollar LIBOR, and the Canadian Overnight Repo Rate Average (“CORRA”), in the case of the Canadian Dollar Offered Rate ("CDOR"). The adoption of these amendments did not have a material impact on our Consolidated Financial Statements.

All LIBOR settings were either discontinued or declared non-representative on or before June 30, 2023. On May 16, 2022, Refinitiv Benchmark Services (UK) Limited, the administrator of CDOR, announced that it will permanently cease the publication of all three tenors of CDOR after June 28, 2024. Concurrently, OSFI published their expectation that Federally Regulated Financial Institutions ("FRFIs") transition all new derivatives and securities to an ARR by June 30, 2023, with no new CDOR exposure being recognized after that date (with limited exceptions for risk management requirements), and that loan agreements referencing CDOR be transitioned by June 28, 2024. FRFIs are also expected to prioritize system and model updates to accommodate the use of CORRA (or any alternative reference rates, as necessary) prior to such date.

Also, with the cessation of CDOR’s publication, the Bankers’ Acceptance (“BA”) lending model will be discontinued, and BA issuance is expected to cease. To facilitate the Canadian loan markets’ move away from CDOR and BAs, on July 27, 2023, the Canadian Alternative Reference Rate working group (“CARR”), established by the Canadian Fixed-Income Forum committee of the Bank of Canada (“CFIF”), has implemented a milestone in its two-stage transition plan whereby no new CDOR or BA-related contract should be entered into after November 1, 2023.  CFIF has formed a BA-related working group to facilitate a smooth transition away from BAs and to assess potential options to replace them.

In preparation for the above-mentioned benchmark reform, we implemented an Interbank Offered Rate ("IBOR") Transition Program (the "Program") to manage the transition from LIBOR and CDOR to appropriate ARRs. The Program is cross-functional in nature and comprises key stakeholders across our organization and operates with executive oversight. The Program is on track in executing its transition plan, and is mindful of incorporating market developments as they arise. We also actively participate in industry associations and incorporate best practice guidance from these industry associations, as well as regulatory bodies, into the transition plan, such as reviewing and remediating our IBOR-based contracts to incorporate appropriate fallback language. The Program is designed to address the risk and uncertainty relating to our transition to ARRs and other factors relating to reform that could otherwise adversely affect our operations and cash flows and the value of and return on our investments that are IBOR-based. Our affiliated entities with IBOR exposure related to derivatives adhered to the ISDA 2020 IBOR Fallbacks Protocol prior to June 30, 2023, facilitating the transition of our legacy derivative contracts to appropriate ARRs. Our GBP LIBOR exposure transitioned to Sterling Overnight Index Average, and our remaining US dollar LIBOR and CDOR exposure has transitioned or is expected to transition to appropriate ARRs in the first half of 2024.

As at December 31, 2023, our exposure to US dollar LIBOR consists of non-derivative financial assets of $86 million (December 31, 2022 — $2,750 million), non-derivative financial liabilities of $nil (December 31, 2022 — $77 million) and derivative notional of $nil (December 31, 2022 — $1,683 million) that have not yet been confirmed to have transitioned to SOFR. Our exposure to CDOR consists of non-derivative financial assets of $589 million (December 31, 2022 — $396 million), non-derivative financial liabilities of $4,896 million (December 31, 2022 — $5,892 million), and derivative notional of $9,159 million (December 31, 2022 — $11,725 million) that have not yet transitioned to CORRA, excluding financial instruments maturing by June 28, 2024, and including derivatives that are expected to automatically transition to CDOR upon its cessation.

Revised accounting policies on adoption of IFRS 9
For more information about the revised accounting policies as a result of the adoption of IFRS 9 that differ from those included in our 2022
Annual Consolidated Financial Statements, refer to heading "IFRS 9 Financial Instruments" in Note 2.A.ii of our 2023 Annual Consolidated Financial Statements.

2.A.ii Other Amended International Financial Reporting Standards Adopted in 2023

We adopted the following amendments to IFRS on January 1, 2023. The adoption of these amendments did not have a material impact on our Consolidated Financial Statements:

In May 2021, the IASB issued amendments to IAS 12 Income Taxes ("IAS 12"). The amendments, Deferred Tax related to Assets and Liabilities arising from a Single Transaction, narrow the scope of the recognition exemption in IAS 12 so that it no longer applies to transactions that, on initial recognition, give rise to equal taxable and deductible temporary differences.

In February 2021, the IASB issued amendments to IAS 1 Presentation of Financial Statements ("IAS 1") and IFRS Practice Statement 2 Making Materiality Judgments ("IFRS Practice Statement 2"). The amendments to IAS 1 require companies to disclose their material accounting policy information rather than their significant accounting policies. The amendments to IFRS Practice Statement 2 provide guidance on how to apply the concept of materiality to accounting policy disclosures.

In February 2021, the IASB issued amendments to IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors. The amendments clarify how companies should distinguish changes in accounting policies from changes in accounting estimates.

In May 2023, the IASB issued amendments to IAS 12 to give temporary relief from accounting for deferred taxes arising from Pillar Two model rules, which the Organization for Economic Co-operation and Development ("OECD") published in December 2021. The amendments introduce a mandatory temporary exception to the accounting for deferred taxes arising from jurisdictions implementing the global tax rules
                 MANAGEMENT'S DISCUSSION & ANALYSIS Sun Life Financial Inc. December 31, 2023 111


and disclosure requirements for affected entities to help users better understand an entity’s exposure to Pillar Two income taxes arising from that legislation, particularly before its effective date. Effective upon issuance, we have applied the mandatory temporary exception which is effective immediately.

On August 4, 2023, the Canadian Department of Finance released draft legislation to implement certain previously announced measures, including application rules for a 15% global minimum tax under OECD’s two-pillar plan, which will apply to Sun Life effective January 1, 2024, however the timing of the substantive enactment of these rules in most jurisdictions where Sun Life operates is uncertain. The Pillar Two rules are not expected to have a material impact on Sun Life’s consolidated financial statements when they become effective.

2.B New and Amended International Financial Reporting Standards to be Adopted in 2024

The following new and amended IFRS were issued by the IASB. We expect to adopt these in 2024:

In September 2022, the IASB issued amendments to IFRS 16 to add subsequent measurement requirements for sale and leaseback transactions that satisfy the requirements in IFRS 15 Revenue from Contracts with Customers to be accounted for as a sale. The amendments require a seller-lessee to subsequently measure lease liabilities arising from a leaseback in a way that it does not recognize any amount of the gain or loss that relates to the right of use it retains. The amendments to IFRS 16 will be effective for annual reporting period beginning on or after January 1, 2024, with early application permitted. We do not expect the adoption of these amendments to have a material impact on our Consolidated Financial Statements.

3. Disclosure Controls and Procedures
The Company has established disclosure controls and procedures that are designed to provide reasonable assurance that all relevant information is gathered and reported to senior management, including the Company's President and CEO, Executive Vice-President and Chief Financial Officer ("CFO"), and Executive Vice-President, Chief Legal Officer and Public Affairs, on a timely basis so that appropriate decisions can be made regarding public disclosure.

An evaluation of the effectiveness of our disclosure controls and procedures, as defined under rules adopted by the Canadian securities regulatory authorities and the SEC, as at December 31, 2023, was carried out under the supervision of and with the participation of the Company's management, including the CEO and the CFO. Based on our evaluation, the CEO and the CFO concluded that the design and operation of these disclosure controls and procedures were effective as at December 31, 2023.

Management's Report on Internal Control over Financial Reporting
Management is responsible for establishing and maintaining adequate internal control over financial reporting to provide reasonable assurance regarding the reliability of our financial reporting and the preparation of our financial statements in accordance with IFRS.

Due to its inherent limitations, internal control over financial reporting may not prevent or detect misstatements on a timely basis. Projections of any evaluation of the effectiveness of internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
We conducted an assessment of the effectiveness of our internal control over financial reporting, as of December 31, 2023, based on the framework and criteria established in Internal Control-Integrated Framework (2013), issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on that assessment, we have concluded that our internal control over financial reporting was effective as of December 31, 2023.

Our internal control over financial reporting, as of December 31, 2023, has been audited by the Company's external auditor, Deloitte LLP, Independent Registered Public Accounting Firm, who also audited our Annual Consolidated Financial Statements for the year ended December 31, 2023. As stated in the Report of Independent Registered Public Accounting Firm, they have expressed an unqualified opinion on our internal control over financial reporting as of December 31, 2023.

Changes in Internal Control over Financial Reporting
As a result of the adoption of IFRS 17 and IFRS 9, effective January 1, 2023, we made the necessary technology updates and modifications to the financial reporting processes and controls related to actuarial, finance, ALM and investments to comply with the requirements of the new accounting standards. No changes were made in our internal control over financial reporting for the period which began on January 1, 2023 and ended December 31, 2023 that have materially affected or are reasonably likely to materially affect our internal control over financial reporting.

O. Legal and Regulatory Proceedings
Information concerning legal and regulatory matters is provided in our Annual Consolidated Financial Statements and the AIF, in each case for the year ended December 31, 2023.

P. Forward-looking Statements

MANAGEMENT'S DISCUSSION & ANALYSIS From time to time, the Company makes written or oral forward-looking statements within the meaning of certain securities laws, including the “safe harbour” provisions of the United States Private Securities Litigation Reform Act of 1995 and applicable Canadian securities legislation. Forward-looking statements contained in this document include statements (i) relating to our strategies; (ii) relating to expectations with respect to the Bermuda Corporate Income Tax Change and its impact on our consolidated financial statements; (iii) relating to the use of proceeds of our sustainability bond offering; (iv) relating to our normal course issuer bid (including, but not limited to, statements regarding future purchases of common shares under the NCIB); (v) relating to MFS going to market with active ETFs over the next year; (vi) relating to the expected operational launch of SLCSI in 2024; (vii) relating to the expected full launch of our Diabetes Signature Solutions products in 2024; (viii) relating to expected changes in our LICAT ratio; (ix) relating to our growth initiatives and other business objectives; (x) relating to our targets, goals and commitments (including with respect to our sustainability plan and net zero emissions); (xi) relating to our expected tax range for future years; (xii) set out in this document under the heading K - Risk Management - Market Risk Sensitivities - Interest Rate Sensitivities; (xiii) relating to the expected impact of the Pillar Two rules; (xiv) relating to legislation issued by the Canadian Department of Finance potentially limiting the deductibility of interest and financing expenses for Canadian tax purposes, if enacted; (xv) relating to our remaining US dollar LIBOR and CDOR exposure transitioning to appropriate ARRs in the first half of 2024; (xvi) relating to the expected impact of the adoption of the amendments to IFRS 16; (xvii) that are predictive in nature or that depend upon or refer to future events or conditions; and (xviii) that include words such as “achieve”, “aim”, “ambition”, “anticipate”, “aspiration”, “assumption”, “believe”, “could”, “estimate”, “expect”, “goal”, “initiatives”, “intend”, “may”, “objective”, “outlook”, “plan”, “project”, “seek”, “should”, “strategy”, “strive”, “target”, “will”, and similar expressions. Forward-looking statements include the information concerning our possible or assumed future results of operations. These statements represent our current expectations, estimates, and projections regarding future events and are not historical facts, and remain subject to change.

Forward-looking statements are not a guarantee of future performance and involve risks and uncertainties that are difficult to predict. Future results and shareholder value may differ materially from those expressed in these forward-looking statements. Our ability to achieve our net-zero GHG emissions reduction goals and targets is based on a number of assumptions and is subject to a number of factors beyond our control, including the availability of comprehensive, comparable and high-quality GHG emissions data, the need for active and continued participation of stakeholders (including enterprises, financial institutions and governmental and non-governmental organizations), the establishment and fulfilment of climate commitments and net-zero targets by governments and companies, the development and deployment of new technologies and industry-specific solutions including in hard-to-abate sectors, international cooperation, and the development of regulations internationally. The energy transition will not be linear and the pace of decarbonization for different sectors and countries will vary. We intend to review and potentially revise our emissions reduction goals and targets as appropriate as data quality and methodologies improve and as best practices, regulations and climate science continue to evolve. Other factors that may cause actual results and shareholder value to differ materially from those expressed in the forward-looking statements include the matters set out in this document under the headings D - Profitability - 5 - Income taxes, G - Financial Strength and K - Risk Management and in SLF Inc.’s 2023 AIF under the heading Risk Factors, and the factors detailed in SLF Inc.’s other filings with Canadian and U.S. securities regulators, which are available for review at www.sedarplus.ca and www.sec.gov, respectively.

Medium-Term Financial Objectives
The Company's medium-term financial objectives set out in section B - Overview - 2 - Financial Objectives are forward-looking non-IFRS financial measures. Our ability to achieve those objectives is dependent on our success in achieving growth initiatives and business objectives and on certain key assumptions that include: (i) no significant changes in the level of interest rates; (ii) average total return on real estate and equity investments of approximately 8% per annum; (iii) credit experience in line with expectations; (iv) no significant changes in the level of our regulatory capital requirements; (v) no significant changes to our effective tax rate; (vi) no significant increase in the number of shares outstanding; and (vii) other key assumptions include: no material changes to our hedging program, hedging costs that are consistent with our expectations, no material assumption changes and no material accounting standard changes. Our underlying ROE is dependent upon capital levels and options for deployment of excess capital. Our medium-term financial objectives do not reflect the indirect effects of interest rate and equity market movements including the potential impacts on goodwill or the current valuation allowance on deferred tax assets as well as other items that may be non-operational in nature.

Our target dividend payout ratio of 40%-50% of our underlying net income assumes that economic conditions and our results will enable us to maintain our payout ratio in the target range, while maintaining a strong capital position. The declaration, amount and payment of dividends is subject to the approval of SLF Inc.'s Board of Directors and our compliance with the capital requirements in the Insurance Companies Act (Canada). Additional information on dividends is provided in the section J - Capital and Liquidity Management - 3 - Shareholder Dividends in this MD&A.

Although considered reasonable by the Company, we may not be able to achieve our medium-term financial objectives as the assumptions on which these objectives were based may prove to be inaccurate. Accordingly, our actual results could differ materially from our medium-term financial objectives as described in the section B - Overview - 2 - Financial Objectives in this MD&A. Our medium-term financial objectives do not constitute guidance.

Financial Reporting Responsibilities
lineslfblue100a04.jpg

Management is responsible for preparing the Consolidated Financial Statements. This responsibility includes selecting appropriate accounting policies and making estimates and other judgments consistent with International Financial Reporting Standards. The financial information presented elsewhere in the annual report to shareholders is consistent with these Consolidated Financial Statements.

The Board of Directors ("Board") oversees management’s responsibilities for financial reporting. An Audit Committee of non-management directors is appointed by the Board to review the Consolidated Financial Statements and report to the Board prior to their approval of the Consolidated Financial Statements for issuance to shareholders. Other key responsibilities of the Audit Committee include reviewing the Company’s existing internal control procedures and planned revisions to those procedures, and advising the Board on auditing matters and financial reporting issues.

Management is also responsible for maintaining systems of internal control that provide reasonable assurance that financial information is reliable, that all financial transactions are properly authorized, that assets are safeguarded, and that Sun Life Financial Inc. and its subsidiaries, collectively referred to as "the Company", adhere to legislative and regulatory requirements. These systems include the communication of policies and the Company’s Code of Business Conduct throughout the organization. Internal controls are reviewed and evaluated by the Company’s internal auditors.

Management conducted an assessment of the effectiveness of the Company’s internal control over financial reporting, as of     December 31, 2023, based on the framework and criteria established in Internal Control - Integrated Framework (2013), issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on that assessment, management has concluded that the Company’s internal control over financial reporting was effective as of December 31, 2023.

The Audit Committee also conducts such review and inquiry of management and the internal and external auditors as it deems necessary towards establishing that the Company is employing appropriate systems of internal control, is adhering to legislative and regulatory requirements and is applying the Company’s Code of Business Conduct. Both the internal and external auditors and the Company’s Appointed Actuary have full and unrestricted access to the Audit Committee with and without the presence of management.

The Office of the Superintendent of Financial Institutions, Canada conducts periodic examinations of the Company. These examinations are designed to evaluate compliance with provisions of the Insurance Companies Act (Canada) and to ensure that the interests of policyholders, depositors, and the public are safeguarded. The Company’s foreign operations and foreign subsidiaries are examined by regulators in their local jurisdictions.

The Company’s Appointed Actuary, who is a member of management, is appointed by the Board to discharge the various actuarial responsibilities required under the Insurance Companies Act (Canada), and conducts the valuation of the Company’s actuarial liabilities. The role of the Appointed Actuary is described in more detail in Note 10. The report of the Appointed Actuary accompanies these Consolidated Financial Statements.

The Company’s external auditor, Deloitte LLP, Independent Registered Public Accounting Firm, has audited the Company’s internal control over financial reporting as of December 31, 2023, in addition to auditing the Company’s Consolidated Financial Statements for the years ended December 31, 2023 and December 31, 2022. Its reports to the Board and shareholders express unqualified opinions and accompany these Consolidated Financial Statements. Deloitte LLP meets separately with both management and the Audit Committee to discuss the results of its audit.

Appointed Actuary’s Report    
lineslfblue100a04.jpg

I have valued the policy liabilities and reinsurance recoverables of Sun Life Financial Inc. and its subsidiaries for its Consolidated Statements of Financial Position at December 31, 2023 and December 31, 2022 and their change in the Consolidated Statements of Operations for the year ended December 31, 2023 in accordance with accepted actuarial practice in Canada, including selection of appropriate assumptions and methods.

In my opinion, the amount of policy liabilities net of reinsurance recoverables makes appropriate provision for all policy obligations and the Consolidated Financial Statements fairly present the results of the valuation.

Report of Independent Registered Public Accounting Firm
To the Shareholders and the Board of Directors of Sun Life Financial Inc.

Opinion on the Financial Statements
December 31, 2023 Independent Auditor's Report We have audited the accompanying consolidated statements of financial position of Sun Life Financial Inc. and subsidiaries (the “Company”) as of December 31, 2023 and 2022, the related consolidated statements of operations, comprehensive income (loss), changes in equity, and cash flows, for each of the two years in the period ended December 31, 2023, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2023 and 2022, and its financial performance and its cash flows for each of the two years in the period ended December 31, 2023, in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board (“IFRS”).We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 7, 2024, expressed an unqualified opinion on the Company’s internal control over financial reporting.

Adoption of New Accounting Standards
As discussed in Note 2.A to the financial statements, the Company changed its method of accounting for insurance contracts and financial instruments in 2023 due to the adoption of IFRS 17, Insurance Contracts (“IFRS 17”) and IFRS 9, Financial Instruments.

Basis for Opinion
These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters
The critical audit matters communicated below are matters arising from the current-period audit of the financial statements that were communicated or required to be communicated to the audit committee and that (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Insurance Contract Liabilities - Refer to Notes 1 and 10 to the Financial Statements
Critical Audit Matter Description
The Company’s insurance contract liabilities represent a significant portion of its total liabilities. Insurance contract liabilities are determined in accordance with IFRS 17. This requires the use of complex valuation models and assumptions to measure groups of insurance contracts as the total of fulfillment cash flows, plus a risk adjustment for non-financial risk and a contractual service margin (“CSM”). The CSM component is only relevant for groups of insurance contracts measured using the general measurement approach and the variable fee approach.

While there is considerable judgment applied by management and inherent uncertainty in selecting assumptions, the assumptions with the greatest estimation uncertainty are those related to mortality, policyholder behaviour and discount rates. These assumptions required significant auditor attention particularly for (i) circumstances where there is limited Company and industry experience data, (ii) circumstances where the historical experience may not be a good indicator of the future, and (iii) the determination of discount rates, which requires complex calculation and measurement of unobservable market inputs. Auditing certain valuation models and significant assumptions (mortality, policyholder behaviour and discount rates) required a high degree of auditor judgment and an increased extent of audit effort, including the need to involve actuarial and fair value specialists.

How the Critical Audit Matter Was Addressed in the Audit
Our audit procedures related to certain valuation models and significant assumptions included the following, among others:
•Evaluated and tested the effectiveness of controls over actuarial models and the determination of the mortality, policyholder behaviour and discount rate assumptions used in the calculation of insurance contract liabilities, as well as access and change management controls over those actuarial models.
•With the assistance of actuarial and fair value specialists, tested the appropriateness of certain valuation models used in the valuation process by:
•Calculating an independent estimate of the insurance contract liability for a sample of insurance policies and comparing the results to the Company’s estimate; and
•Testing the accuracy of certain valuation models for changes in key assumptions.
•With the assistance of actuarial specialists, tested the reasonableness of mortality and policyholder behaviour assumptions by:
•Evaluating whether management’s assumptions were determined in accordance with the requirements of IFRS 17;
•Testing experience studies and other inputs used in the determination of the assumptions; and
•Analyzing management’s interpretation and judgment with respect to its experience study results and emerging claims experience, evaluating new and revised key assumptions, assessing reasonable possible alternative assumptions, and considering industry and other external sources of benchmarking where applicable.
Report of Independent Registered Public Accounting Firm Sun Life Financial Inc. December 31, 2023 7


•With the assistance of actuarial and fair value specialists, evaluated the reasonableness of the discount rates used by:
•Evaluating whether management’s assumptions and methodologies were determined in accordance with the requirements of IFRS 17; and
•Testing the inputs and source information underlying the determination of the discount rates and developing a range of independent estimates, and comparing those to the discount rates selected by management.

Valuation of Investment Properties - Refer to Notes 1 and 5 to the Financial Statements
Critical Audit Matter Description
Investment properties are accounted for at fair value. The fair values of investment properties are generally determined using property valuation models and are based on expected capitalization rates and models that discount expected future net cash flows at current market expected rates of return reflective of the characteristics, location, and market of each property. Expected future net cash flows include contractual and projected cash flows and forecasted operating expenses, and take into account discount, rental, and occupancy rates derived from market surveys. The estimates of future cash inflows in addition to expected rental income from current leases, include projected income from future leases based on significant assumptions that are consistent with current market conditions.

The assumptions with the greatest uncertainty are the discount rates, terminal capitalization rates, and future rental rates. Performing audit procedures to assess inputs required a high degree of auditor judgment and an increased extent of audit effort, including the need for the integral involvement of valuation specialists.

How the Critical Audit Matter Was Addressed in the Audit
Our audit procedures related to valuation models and assumptions including discount rates, terminal capitalization rates, and future rental rates included the following, among others:
•Evaluated and tested the effectiveness of controls over the fair value process for investment properties. These controls include an assessment and approval by senior management of the discount rates, terminal capitalization rates, and future rental rates assumptions used in the determination of the valuation of investment properties and the valuation conclusions relative to comparable properties.
•With the assistance of valuation specialists, evaluated on a sample basis the reasonableness of management’s discount rates, terminal capitalization rates, and future rental rates assumptions and valuation conclusions by comparing them to the discount rates, terminal capitalization rates, and future rental rates of market surveys and transactions in comparable properties.

Adoption of New and Amended Accounting Standards - IFRS 17, Insurance Contracts - Refer to Note 2 to the Financial Statements
Critical Audit Matter Description
The Company adopted IFRS 17 effective January 1, 2023. The adoption of IFRS 17 was done on a retrospective basis which had an impact on the Company’s January 1, 2022 opening equity balances. IFRS 17 is a complex accounting standard requiring considerable judgment and interpretation in its implementation, and impacts how the Company recognizes, measures, presents and discloses insurance contracts. In adopting the new standard, the Company used significant judgment in developing and implementing accounting policies, including policies specific to transition. Of particular importance, the Company elected to use the fair value approach for groups of insurance contracts where full retrospective application was impracticable. Under the fair value approach, the CSM at transition is equal to the fair value of a group of insurance contracts less the fulfillment cash flows measured at that date.

There are many elements embedded in the determination of the fair value for groups of insurance contracts that required management to use significant judgment in making estimates and assumptions related to (1) the appropriateness of the fair value methodology and calculations, (2) the appropriateness of the fair value adjustments to fulfilment cash flows and (3) the appropriateness of the discount rates. Auditing the development and implementation of IFRS 17 accounting policies and the judgments, assumptions and estimates used in fair value determination for groups of insurance contracts required a high degree of auditor judgment and an increased extent of audit effort, including the need to involve fair value, technical accounting and actuarial specialists.

How the Critical Audit Matter Was Addressed in the Audit
December 31, 2023 Report of Independent Registered Public Accounting Firm With the assistance of various specialists, our audit procedures related to the development and implementation of IFRS 17 accounting policies and judgments, assumptions and estimates used in the fair value determination for groups of insurance contracts as at January 1, 2022 included the following, among others:
•Evaluated and tested the effectiveness of controls over the implementation of IFRS 17 accounting policies and the significant estimates and assumptions used in the fair value determination for groups of insurance contracts.
•Evaluated the appropriateness of management’s accounting policies and tested that they were appropriately implemented.
•Evaluated the fair value approach methodology and related fair value adjustments against the requirements of IFRS 17 and IFRS 13, Fair Value Measurement (“IFRS 13”) by:
•Evaluating the methodologies and fair value adjustments and their applicability under IFRS 17 and IFRS 13;
•Examining the audited historical projected cashflows and assumptions to ensure they are incorporated into the transition valuation models as applicable;
•Evaluating new and revised key assumptions under IFRS 17; and
•Testing the appropriateness of certain valuation models used in the estimation process by calculating an independent estimate of the insurance contract liability for a sample of insurance policies and comparing the results to the Company’s estimate.
•Evaluated the reasonableness of the discount rates used to determine fair value by:
•Evaluating whether management’s assumptions and methodologies were determined in accordance with the requirements of IFRS 17 and IFRS 13; and
•Testing the inputs and source information underlying the determination of the discount rates and developing a range of independent estimates and comparing those to the discount rates selected by management.

Report of Independent Registered Public Accounting Firm Sun Life Financial Inc. December 31, 2023 9


Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Directors of Sun Life Financial Inc.

Opinion on Internal Control over Financial Reporting
We have audited the internal control over financial reporting of Sun Life Financial Inc. and subsidiaries (the “Company”) as of December 31, 2023, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control - Integrated Framework (2013) issued by COSO.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the year ended December 31, 2023, of the Company and our report dated February 7, 2024, expressed an unqualified opinion on those financial statements and included an explanatory paragraph regarding the Company’s adoption of new accounting standards.

Basis for Opinion
The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Notes to the Consolidated Financial Statements

(Amounts in millions of Canadian dollars, except for per share amounts and where otherwise stated. All amounts stated in U.S. dollars are in millions.)

1. Material Accounting Policies
Description of Business
Sun Life Financial Inc. ("SLF Inc.") is a publicly traded company domiciled in Canada and is the holding company of Sun Life Assurance Company of Canada ("Sun Life Assurance"). Both companies are incorporated under the Insurance Companies Act (Canada), and are regulated by the Office of the Superintendent of Financial Institutions, Canada ("OSFI"). SLF Inc. and its subsidiaries are collectively referred to as "us", "our", "ours", "we", or "the Company". We are an internationally diversified financial services organization providing savings, retirement and pension products, and life and health insurance to individuals and groups through our operations in Canada, the United States ("U.S."), Asia, and the United Kingdom ("UK"). Effective the second quarter of 2023, we completed the sale of our UK Business unit. We also operate mutual fund and investment management businesses, primarily in Canada, the U.S., and Asia.
Statement of Compliance
We prepared our Consolidated Financial Statements in accordance with International Financial Reporting Standards ("IFRS") as issued by the International Accounting Standards Board ("IASB"). Our accounting policies have been applied consistently within our Consolidated Financial Statements.
Basis of Presentation
Our Consolidated Statements of Financial Position are presented in the order of liquidity and each statement of financial position line item includes both current and non-current balances, as applicable.

We have defined our reportable business segments and the amounts disclosed for those segments based on our management structure and the manner in which our internal financial reporting is conducted. Transactions between segments are executed and priced on an arm’s-length basis in a manner similar to transactions with third parties.

The material accounting policies used in the preparation of our Consolidated Financial Statements are summarized below and are applied consistently.
Estimates, Assumptions and Judgments
The application of our accounting policies requires estimates, assumptions and judgments as they relate to matters that are inherently uncertain. We have established procedures to ensure that our accounting policies are applied consistently and that the processes for changing methodologies for determining estimates are controlled and occur in an appropriate and systematic manner.
Use of Estimates and Assumptions
The preparation of our Consolidated Financial Statements requires us to make estimates and assumptions that affect the application of our policies and the reported amounts of assets, liabilities, revenue and expenses. Key sources of estimation uncertainty include the measurement of insurance contract assets and liabilities, reinsurance contract held assets and liabilities and investment contract liabilities, determination of fair value, determination and impairment of goodwill and intangible assets, determination of provisions and liabilities for pension plans, other post-retirement benefits, income taxes, and the determination of fair value of share-based payments. Actual results may differ from our estimates thereby impacting our Consolidated Financial Statements. Information on our use of estimates and assumptions is discussed in this Note and other Notes.
Judgments
In preparation of these Consolidated Financial Statements, we use judgments to select assumptions and determine estimates as described above. We also use judgment when applying accounting policies and when determining the classification of insurance contracts, investment contracts and service contracts; the substance of whether our relationship with a structured entity, subsidiary, joint venture or associate constitutes control, joint control or significant influence; functional currencies; contingencies; acquisitions; deferred income tax assets; and the determination of cash generating unit ("CGU").

Basis of Consolidation
Our Consolidated Financial Statements include the results of operations and the financial position of subsidiaries, which includes structured entities controlled by us, after intercompany balances and transactions have been eliminated. Subsidiaries are fully consolidated from the date we obtain control, and deconsolidated on the date control ceases. The acquisition method is used to account for the acquisition of a subsidiary from an unrelated party at the date that control is obtained, with the difference between the consideration transferred and the fair value of the subsidiary’s net identifiable assets acquired recorded as goodwill. Judgment is required to determine fair value of the net identifiable assets acquired in a business combination. Interests in controlled entities held by external parties are reported as non-controlling interests ("NCI").

We control an entity when we have power over an entity, exposure to or rights to variable returns from our involvement with an entity, and the ability to affect our returns through our power over an entity. Power exists when we have rights that give us the ability to direct the relevant activities, which are those activities that could significantly affect the entity’s returns. Power can be obtained through voting rights or other contractual arrangements. Judgment is required to determine the relevant activities and which party has power over these activities. When we have power over and variable returns from an entity, including an investment fund that we manage, we also apply significant judgment in determining whether we are acting as a principal or agent. To make this determination, we consider factors such as how much discretion we have regarding the management of the investment fund and the magnitude and extent of variability associated with our interests in the fund. If we determine we are the principal rather than the agent, we would consolidate the assets and liabilities of the fund. Interests held by external parties in investment funds that we consolidate are recorded as third-party interest in consolidated investment funds in Other liabilities. If we lose control of an entity, the assets and liabilities of that entity are derecognized from our Consolidated Statements of Financial Position at the date at which control is lost and any investment retained is remeasured to fair value.

A joint venture exists when SLF Inc., or one of its subsidiaries, has joint control of a joint arrangement and has rights to the net assets of the arrangement. Joint control is the contractually agreed sharing of control and exists only when the decisions about the relevant activities require the unanimous consent of the parties sharing control. Associates are entities over which SLF Inc. or its subsidiaries are able to exercise significant influence. Significant influence is the power to participate in the financial and operating policy decisions of an investee but not have control or joint control over those decisions. Significant influence is generally presumed to exist when SLF Inc. or its subsidiaries holds greater than 20% of the voting power of the investee but does not have control or joint control. The equity method is used to account for our interests in joint ventures and associates. A joint operation exists when SLF Inc., or one of its subsidiaries, has joint control of an arrangement that gives it rights to the assets and obligations for the liabilities of the operation, rather than the net assets of the arrangement. For joint operations, we record our share of the assets, liabilities, revenue and expenses of the joint operation. Judgment is required to determine whether contractual arrangements between multiple parties results in control, joint control or significant influence, with consideration of the relevant activities of the entity, voting rights, representation on boards of directors and other decision-making factors. Judgment is also required to determine if a joint arrangement is a joint venture or joint operation, with consideration of our rights and obligations and the structure and legal form of the arrangement.
Determination of Fair Value
Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. Fair value is measured using the assumptions that market participants would use when pricing an asset or liability. We determine fair value by using quoted prices in active markets for identical or similar assets or liabilities. When quoted prices in active markets are not available, fair value is determined using valuation techniques that maximize the use of observable inputs. When observable valuation inputs are not available, significant judgment is required to determine fair value by assessing the valuation techniques and valuation inputs. The use of alternative valuation techniques or valuation inputs may result in a different fair value. A description of the fair value methodologies, assumptions, valuation techniques, and valuation inputs by type of asset is included in Note 5. A description of the fair value methodologies, assumptions, valuation techniques and valuation inputs for the transition of insurance contracts to IFRS 17 Insurance Contracts ("IFRS 17") is included in Note 10.
Notes to the Consolidated Financial Statements     Sun Life Financial Inc. December 31, 2023 17


Foreign Currency Translation
Translation of Transactions in Foreign Currencies
The financial results of SLF Inc. and its subsidiaries, joint ventures and associates are prepared in the currency in which they conduct their ordinary course of business, which is referred to as functional currency. Transactions occurring in currencies other than the functional currency are translated to the functional currency using the spot exchange rates at the dates of the transactions.

Monetary assets and liabilities in foreign currencies are translated to the functional currency at the exchange rate at the statement of financial position date. Insurance contract and reinsurance contract held assets and liabilities, including the contractual service margin ("CSM"), are monetary items. Non-monetary assets and liabilities in foreign currencies that are held at fair value are translated using the exchange rate at the statement of financial position date, while non-monetary assets and liabilities that are measured at historical cost are translated using the exchange rate at the date of the transaction.

The resulting exchange differences from the translation of monetary items and non-monetary items held at fair value, with changes in fair value recorded to income, are recognized in our Consolidated Statements of Operations. For monetary assets classified as fair value through other comprehensive income ("FVOCI"), translation differences calculated on amortized cost are recognized in our Consolidated Statements of Operations and other changes in carrying amount are recognized in other comprehensive income ("OCI"). The exchange differences from the translation of non-monetary items on these assets are recognized in OCI.
Translation to the Presentation Currency
In preparing our Consolidated Financial Statements, the financial statements of foreign operations are translated from their respective functional currencies to Canadian dollars, our presentation currency. Assets and liabilities are translated at the closing exchange rate at the statement of financial position date, and income and expenses are translated using the average exchange rates. The accumulated gains or losses arising from translation of functional currencies to the presentation currency, net of the effect of any hedges, are included as a separate component of OCI within equity. Upon disposal of a foreign operation that includes loss of control, significant influence or joint control, the cumulative exchange gain or loss related to that foreign operation is recognized in income.
Invested Assets
Financial Assets Excluding Derivative Financial Instruments (IFRS 9)
Financial assets include cash, cash equivalents and short-term securities, debt securities, equity securities, mortgages and loans, and other financial invested assets.
i) Initial Recognition and Subsequent Measurement
Classification of financial assets
Financial assets are measured at initial recognition at fair value and are classified as and subsequently measured at fair value through profit or loss ("FVTPL"), FVOCI, or amortized cost based on the business model used to manage the financial asset and the contractual cash flow characteristics of the asset. Amortized cost is determined using the effective interest rate method, which is the gross carrying amount less the allowance for ECL. Financial assets are not reclassified subsequent to initial recognition unless the business model used to manage the financial asset has changed. Financial assets are recognized in the Consolidated Statements of Financial Position on their trade dates, which are the dates that we commit to purchase or sell the assets. Originated mortgages and loans are recognized in the Consolidated Statements of Financial Position on their settlement dates.

A financial asset is measured at amortized cost if both of the following conditions are met and the asset is not designated at FVTPL:
•The asset is held within a business model that is held to collect ("HTC"), in which the collection of contractual cash flows from the financial asset is the primary objective and sales are expected to be insignificant or infrequent; and
•The contractual terms of the asset give rise to cash flows that are solely payments of principal and interest ("SPPI") on the principal amount outstanding.

A financial asset is measured at FVOCI if both of the following conditions are met and the asset is not designated at FVTPL:
•The asset is held within a business model that is held to collect and sell ("HTC&S"), in which both the collection of contractual cash flows and the sale of financial assets are integral to achieving the objective of the business model; and
•The contractual terms of the asset give rise, on specified dates, to cash flows that are SPPI.

Financial assets that are managed on a fair value basis and do not meet the objectives of a HTC or HTC&S business model, such as financial assets that are held for trading, are measured at FVTPL and fall within the scope of other business models.

All financial assets not classified as amortized cost or FVOCI, as described above, are measured at FVTPL. Financial assets at FVTPL include financial assets that are held-for-trading. A financial asset is classified as held-for-trading if it is acquired principally for the purpose of selling in the near term. Cash, cash equivalents and short-term securities are held for trading for the purpose of meeting short-term cash requirements and are measured at FVTPL. On initial recognition, we may also make an irrevocable election to designate a financial asset that would otherwise be measured at amortized cost or FVOCI as measured at FVTPL if the financial asset is managed together with a related financial liability and their performance is evaluated on a fair value basis. Certain debt securities, mortgages and loan instruments that support insurance contract liabilities, which are measured at fair value, have been designated at FVTPL, as doing so significantly reduces measurement inconsistency with the related insurance contract liabilities. These financial assets would otherwise have been measured at FVOCI or amortized cost.

Equity securities are measured at FVTPL, unless the asset is not held for trading purposes and we make an irrevocable election to designate the asset at FVOCI. This election is made on an instrument-by-instrument basis. If such an election is made, the fair value changes, including any associated foreign exchange gains or losses, are recognized in OCI and are not subsequently reclassified to the Consolidated Statements of Operations, including upon disposal. Realized gains and losses are transferred directly to retained earnings upon disposal.

18 Sun Life Financial Inc. December 31, 2023 Notes to the Consolidated Financial Statements The following table summarizes the financial assets included in our Consolidated Statements of Financial Position and the applicable classifications:


IFRS 9
Cash, cash equivalents and short-term securities FVTPL

FVTPL, FVOCI
Mortgages and loans FVTPL, FVOCI, Amortized cost
Other financial invested assets

Business model assessment
We determine our business models at the level that best reflects how we manage portfolios of financial assets to achieve our business objectives. Judgment is used in determining our business models, which is supported by relevant, objective evidence including:
•How the economic activities of our businesses generate benefits, for example, through enhancing yields or hedging and how such economic activities are evaluated and reported to key management personnel;
•The significant risks affecting the performance of our businesses, for example, market risk, credit risk, or other risks as described in the Risk Management section of Management’s Discussion and Analysis, and the activities undertaken to manage those risks;
•The frequency, volume, and timing of sales in prior periods, the reasons for the sales and expectations about future sales activity. Information about sales activity is not considered in isolation, but as part of an overall assessment of how our stated objective for managing the financial assets is achieved and how cash flows are realized; and
•The compensation structures for managers of our businesses, to the extent that these are directly linked to the economic performance of the business model.

Our business models include HTC, HTC&S and other, as described above.
Assessment of whether contractual cash flows are SPPI
Financial assets held within a HTC or HTC&S business model are assessed to evaluate if their contractual cash flows are comprised of SPPI. SPPI payments are those which would typically be expected from basic lending arrangements, such as interest and basic lending returns, compensation for credit risk and the time value of money, costs associated with holding the financial asset for a period of time, and a profit margin. In making the SPPI assessment, we consider the contractual terms of the instrument, including assessment of whether the timing or amount of the contractual cash flows could change by a contractual term of the financial asset. A prepayment feature is consistent with the SPPI criterion if the prepayment amount substantially represents unpaid amounts of principal and interest on the principal amount outstanding, which may include reasonable compensation for early termination of the contract.

Where the contractual terms introduce exposure to risk or variability of the cash flows that are inconsistent with a basic lending arrangement, the related financial asset is classified as and measured at FVTPL.
Subsequent measurement
Equity securities, debt securities, mortgages and loans, and assets related to Collateralized Loan Obligations ("CLOs") that are classified or designated at FVTPL are recorded at fair value in our Consolidated Statements of Financial Position, and gains or losses, including interest or dividend income and foreign exchange gains and losses, are recognized in Net investment income (loss) in the Consolidated Statements of Operations.

Debt securities and mortgages and loans that are classified as FVOCI are recorded at fair value. Interest income, foreign exchange gains (losses), and impairment are recognized in Net investment income (loss) in the Consolidated Statements of Operations. Other gains or losses are recognized in OCI.

Mortgages and loans classified as amortized cost are subsequently measured using the effective interest rate method. Interest income, foreign exchange gains and losses, and impairment are presented in Net investment income (loss) in the Consolidated Statements of Operations.

Other financial invested assets include investments in limited partnerships, segregated funds, mutual funds, and assets related to CLOs that are classified as FVTPL. These financial assets are recorded at fair value, and gains or losses are recognized in Net investment income (loss) in the Consolidated Statements of Operations. Debt securities and Mortgages and loans included in Other financial invested assets that are classified as FVOCI are recorded at fair value.

Cash equivalents are highly liquid instruments with a term to maturity of three months or less. Cash and cash equivalents are classified as FVTPL and the fair values are assumed to approximate their carrying values, due to their short-term nature or because they are frequently repriced to current market rates. Short-term securities are those that have a term to maturity exceeding three months but less than one year. The fair value of short-term securities is approximated by their carrying amount.
ii) Derecognition
Financial assets are derecognized when our contractual rights to the cash flows of the financial asset have expired, or when we transfer the rights to receive contractual cash flows and substantially all the risks and rewards of owning the financial assets have been transferred. When we neither retain nor transfer substantially all the risks and rewards of ownership, the financial assets are derecognized if control over the financial assets have been relinquished. If we retain control of the financial assets, we continue to recognize the transferred assets to the extent of our continuing involvement.

When financial assets are derecognized, the difference between the carrying amount and the consideration received on the date of derecognition is recognized in Net investment income (loss) in the Consolidated Statements of Operations. For debt securities at FVOCI, the cumulative gains (losses) previously recognized in OCI are reclassified to Net investment income (loss) in the Consolidated Statements of
Notes to the Consolidated Financial Statements     Sun Life Financial Inc. December 31, 2023 19


Operations. For equity investments designated at FVOCI, the cumulative gains (losses) previously recognized in OCI are not reclassified to income.

For financial assets measured at amortized cost in which modifications have resulted in derecognition, the gain (loss) is presented together with impairment losses if the modification was a result of financial difficulties of the borrower. Otherwise, the gain (loss) is presented as Net investment income (loss) in the Consolidated Statements of Operations.

Judgment is applied in determining whether contractual rights to the cash flows from the transferred assets have expired or whether we retain the rights to receive the cash flows on the assets but have assumed an obligation to pay for those cash flows.
iii) Impairment
Policies applicable beginning January 1, 2023
We establish an allowance for expected credit losses ("ECL") for financial assets not classified or designated at FVTPL. Financial assets measured at amortized cost are presented at their carrying amounts on the Consolidated Statements of Financial Position, which is the gross carrying amount less the allowance for ECL, with changes in the allowance for ECL recognized in Provision for credit losses in Net investment income (loss) in the Consolidated Statements of Operations. The allowance for ECL on financial assets measured at FVOCI, including debt securities and mortgages and loans, does not reduce the carrying amount of the assets in the Consolidated Statements of Financial Position, which remains at fair value. Rather, an amount equal to the allowance for ECL that would arise if the assets were measured at amortized cost is recognized in OCI, with changes in the allowance for ECL recognized in Provision for credit losses in Net investment income (loss) in the Consolidated Statements of Operations.

At the end of each reporting period, we apply a three-stage impairment approach to measure the ECL on financial assets measured at amortized cost or at FVOCI:
•Stage 1: For financial assets that have not experienced a significant increase in credit risk since the date of initial recognition, a loss allowance equal to the credit losses expected to result from default events occurring over the 12 months following the reporting date is recognized.
•Stage 2: For financial assets that have experienced a significant increase in credit risk since the date of initial recognition, a loss allowance equal to the credit losses expected to result from default events occurring over the remaining lifetime of the financial asset is recognized.
•Stage 3: When a financial asset is considered to be credit-impaired, a loss allowance equal to the ECL over the remaining lifetime of the financial asset is recognized. Interest income is calculated based on the carrying amount of the asset, net of the loss allowance.

We monitor all financial assets that are subject to impairment for significant increase in credit risk. In making this assessment, we consider both quantitative and qualitative information that is reasonable and supportable, including historical experience and forward-looking information that is available without undue cost or effort. Additional details about significant increase in credit risk and forward-looking information are provided in Note 6.
Modified financial assets
The contractual terms of a financial asset may be modified for a number of reasons, including changing market conditions and other factors not related to a current or potential credit deterioration of the borrower. An existing financial asset whose terms have been modified may be derecognized and the renegotiated asset recognized as a new financial asset at fair value in accordance with the accounting policies in this Note.

If modification does not result in derecognition, the financial asset continues to be subject to the assessment for significant increase in credit risk relative to initial recognition. Expected cash flows arising from the modified contractual terms are considered when calculating the ECL for the modified asset. For loans that were modified while having lifetime ECLs, such loans can revert to having 12-month ECLs if the borrower's financial condition that led to it being identified as credit-impaired are no longer present.
Definition of default
The definition of default used in the measurement of ECL is consistent with the definition of default used for our internal credit risk management purposes. We consider a financial asset to be in default when the issuer is unlikely to meet its credit obligations in full, without recourse action on our part, or when the financial asset is 90 days past due. Our definition of default may differ across financial assets and consider qualitative factors, such as the terms of financial covenants, breaches of such covenants, and other indicators of financial distress, as well as quantitative factors, such as overdue status and non-payment of other obligations under the same issuer. We use internally developed data and those obtained from external sources when assessing default.
Credit-impaired financial assets (Stage 3)
At each reporting date, we assess whether financial assets measured at amortized cost and FVOCI are credit-impaired. A financial asset is credit-impaired when one or more events that have a detrimental impact on the estimated future cash flows of the financial asset have occurred. Evidence of credit-impairment may include indications that the borrower is experiencing significant financial difficulty, probability of bankruptcy or other financial reorganization, as well as a measurable decrease in the estimated future cash flows evidenced by the adverse changes in the payments status of the borrower or economic conditions that correlate with defaults. If a financial asset is credit-impaired, interest income is calculated based on the carrying amount of the asset, which is net of the allowance for ECL, rather than on the gross carrying amount.
Write-off of financial assets
The gross carrying amount of a financial asset, and the related allowance for ECL, is written off (either partially or in full) to the extent that there is no realistic prospect of recovery. This is generally the case when we determine that the borrower does not have assets or sources of income that could generate sufficient cash flows to repay the amounts subject to the write-off. However, financial assets that are written off could still be subject to enforcement activities in order to comply with procedures for recovery of amounts due.

For policies prior to January 1, 2023, please refer to Note 6.A.vi.
20 Sun Life Financial Inc. December 31, 2023 Notes to the Consolidated Financial Statements Under IFRS 9 Financial Instruments ("IFRS 9"), derivatives embedded in contracts where the host is a financial asset in scope of IFRS 9 are not separated.


iv) Embedded Derivatives
Policies applicable beginning January 1, 2023
Instead, the hybrid financial instrument, as a whole, is assessed for classification.

Policies applicable prior to January 1, 2023
An embedded derivative is a component of a host contract that modifies the cash flows of the host contract in a manner similar to a derivative, according to a specified interest rate, financial instrument price, foreign exchange rate, underlying index or other variable. We are required to separate embedded derivatives from the host contract, if an embedded derivative has economic and risk characteristics that are not closely related to the host contract, meets the definition of a derivative, and the combined contract is not measured at fair value with changes recognized in income. If an embedded derivative is bifurcated for accounting purposes from the host contract, it will be accounted for as a derivative. For further details on embedded derivatives in insurance contracts, see the Insurance Contracts accounting policy in this Note.
Collateral
Cash received (pledged) as collateral is recognized (derecognized) in our Consolidated Statements of Financial Position with corresponding amounts recognized in Other liabilities (Other assets), respectively. All other types of assets received (pledged) as collateral are not recognized (derecognized) in our Consolidated Statements of Financial Position.
Derivative Financial Instruments
All derivative financial instruments are recorded at fair value in our Consolidated Statements of Financial Position. Derivatives with a positive fair value are recorded as Derivative assets while derivatives with a negative fair value are recorded as Derivative liabilities.

The accounting for the changes in fair value of a derivative instrument depends on whether or not it is designated as a hedging instrument for hedge accounting purposes. Changes in fair value of derivatives that are not designated for hedge accounting purposes, which are defined as derivative investments, are recorded in Net investment income (loss) in our Consolidated Statements of Operations. Income earned or paid on these derivatives is recorded in Net investment income (loss) in our Consolidated Statements of Operations. Hedge accounting is applied to certain derivatives to reduce income statement volatility. All hedging relationships are documented at inception and hedge effectiveness is assessed at inception and on a quarterly basis to determine whether the hedging instruments are highly effective in offsetting changes attributable to the hedged risk in the fair value or cash flows of the hedged items.
Fair Value Hedges
Certain interest rate swaps and foreign currency forwards are designated as hedging instruments in fair value hedges of the interest rate or foreign exchange rate risks associated with FVOCI assets. Changes in fair value of the derivatives are recorded in Net investment income (loss) in our Consolidated Statements of Operations. The change in fair value of FVOCI assets related to the hedged risk is recognized in profit or loss. As a result, ineffectiveness, if any, is recognized in income to the extent that changes in fair value of the derivatives and FVOCI assets do not offset. Interest income earned and paid on the FVOCI assets and swaps in the fair value hedging relationships are recorded in net investment income in our Consolidated Statements of Operations.
Cash Flow Hedges
Certain equity and foreign currency forwards are designated as hedging instruments in cash flow hedges for anticipated payments of awards under certain share-based payment plans and for anticipated foreign currency purchases of foreign operations. Changes in the fair value of derivatives for the effective portion of the hedge are recognized in OCI, while the ineffective portion of the hedge and any items excluded from the hedging relationship, such as the spot-to-forward differential, are recognized in net investment income in our Consolidated Statements of Operations. A portion of the amount recognized in OCI related to the equity forwards is reclassified to income as a component of Operating expenses as the liabilities for the share-based payment awards are accrued over the vesting period. A portion of the amounts recognized in OCI related to the foreign currency forwards would be reclassified to income upon disposal or impairment of the foreign operations. All amounts recognized in, or reclassified from, OCI are net of related taxes.
Investment Properties
Investment properties are real estate held to earn rental income, for capital appreciation, or both. Properties held to earn rental income or for capital appreciation that have an insignificant portion that is owner-occupied are classified as investment properties. Properties that do not meet these criteria are classified as property and equipment, included in Other assets as described below. Expenditures related to ongoing maintenance of properties incurred subsequent to acquisition are expensed. Investment properties are initially recognized at cost in our Consolidated Statements of Financial Position. Various costs incurred associated with the acquisition of an investment property are either capitalized or expensed depending on whether or not the acquisition is considered a business combination. Investment properties are subsequently measured at fair value with changes in value recorded to Fair value and foreign currency changes on assets and liabilities in our Consolidated Statements of Operations.

When the use of a property changes from owner-occupied to investment property, any gain arising on the remeasurement of the property to fair value at the date of transfer is recognized in our Consolidated Statements of Operations to the extent that it reverses a previous impairment loss. Any remaining increase is recognized in OCI.
Other Non-Financial Invested Assets
Other non-financial invested assets include investments in joint ventures and associates, which are accounted for using the equity method. Investments in joint ventures and associates are initially recorded at cost. The investment in joint ventures and associates is increased by our share of capital contributions and for purchases of additional interests and is reduced by distributions received. In addition, subsequent adjustments to the investment are made for our share of net income or loss and our share of OCI. Our share of net income is recorded in investment income in our Consolidated Statements of Operations and our share of OCI is recorded in our Consolidated Statements of Comprehensive Income (Loss). Impairment losses on equity method investments are recognized when events or changes in circumstances indicate that they are impaired. The impairment loss recognized is the difference between the carrying amount and the recoverable amount.
Notes to the Consolidated Financial Statements     Sun Life Financial Inc. December 31, 2023 21


Other Assets
Other assets, which are measured at amortized cost, include accounts receivable, investment income due and accrued, deferred acquisition costs from service contracts, property and equipment, and lessee’s right-of-use assets. Deferred acquisition costs from service contracts are discussed in the Service contract and fee income section of this Note. Right-of-use assets are discussed in the Leases section of this Note. Owner-occupied properties are amortized to their residual value over 25 to 49 years. Furniture, computers, other office equipment, and leasehold improvements are amortized to their residual value over 2 to 20 years.
Leases
At inception of a contract, we assess whether a contract is, or contains, a lease. A contract is, or contains, a lease if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. For leases where we act as the lessee, we recognize a right-of-use asset and a lease liability at the commencement date of the lease. For leases where we act as the lessor, we assess whether the leases should be classified as finance or operating leases. Our leases are classified as operating leases. Operating leases are recognized into income on a straight-line basis.

The right-of-use asset is initially measured at cost, which is comprised of the initial amount of the lease liability with certain adjustments, and subsequently depreciated using the straight-line method, with depreciation expense included in Operating expenses in the Consolidated Statements of Operations. The right-of-use asset is depreciated to the earlier of the lease term and its useful life. The right-of-use asset is assessed for impairment under IAS 36 Impairment of Assets. Right-of-use assets are assessed for indicators of impairment at each reporting period. If there is an indication that a right-of-use asset may be impaired, an impairment test is performed by comparing the asset’s carrying amount to its recoverable amount. If an impairment loss has been incurred, the carrying value of the right-of-use asset is reduced with the corresponding amount recognized in income.

The lease liability is initially measured at the present value of lease payments over the term of the lease using a discount rate that is based on our incremental borrowing rate. The discount rate is specific to each lease and is determined by various factors, such as the lease term and currency. The lease term includes the non-cancellable period and the optional period where it is reasonably certain we will exercise an extension or termination option, considering various factors that create an economic incentive to do so. Subsequently, the lease liability is measured at amortized cost using the effective interest rate method, with interest charged to Interest expense in the Consolidated Statements of Operations. Lease liabilities and right-of-use assets are remeasured upon lease modifications. A lease modification is considered as a change in the scope of a lease, or the consideration for a lease, that was not part of the original terms and conditions of the lease.
Intangible Assets
Intangible assets consist of finite life and indefinite life intangible assets. Finite life intangible assets are amortized on a straight-line basis or using a units-of-production method, over the useful economic lives: i) Distribution, sales potential of field force, client relationships and asset administration contracts — 3 to 40 years; and ii) Internally generated software — 3 to 10 years. Amortization is charged through Operating expenses in the Consolidated Statements of Operation. The useful lives of finite life intangible assets are reviewed annually, and the amortization is adjusted as necessary. Indefinite life intangibles are not amortized, and are assessed for impairment annually or more frequently if events or changes in circumstances indicate that the asset may be impaired. Impairment is assessed by comparing the carrying values of the indefinite life intangible assets to their recoverable amounts. The recoverable amount is the higher of an asset’s fair value less costs to sell and its value in use. If the carrying values of the indefinite life intangibles exceed their recoverable amounts, these assets are considered impaired, and a charge for impairment is recognized in our Consolidated Statements of Operations. The recoverable amount of intangible assets is determined using various valuation models, which require management to make certain judgments and assumptions that could affect the estimates of the recoverable amount.
Goodwill
Goodwill represents the excess of the cost of an acquisition over the fair value of the net identifiable tangible and intangible assets of the acquired businesses. It is carried at original cost less any impairment subsequently incurred. Goodwill is assessed for impairment annually or more frequently if events or circumstances occur that may result in the recoverable amount of a CGU or a group of CGUs falling below its carrying value. A CGU is the smallest identifiable group of assets that generates cash inflows that are largely independent of cash inflows from other groups of assets. We exercise significant judgment in determining our CGUs. The factors considered in determining our CGUs include product cash inflows, product distribution, target markets, and how management monitors and evaluates the operations.

The goodwill balances are allocated to either individual or groups of CGUs that are expected to benefit from the synergies of the business combination. Goodwill impairment is quantified by comparing a CGU’s or a group of CGUs’ carrying value to its recoverable amount, which is the higher of fair value less costs of disposal and value in use. Impairment losses are recognized immediately and cannot be reversed in future periods. Significant judgment is involved in estimating the model inputs used to determine the recoverable amount of our CGUs or group of CGUs, including those for discount rates, capital, the value of new business, expenses, cash flow projections, and market multiples, due to the uncertainty and the forward-looking nature of these inputs. The assumptions may differ from the actual experience, and estimates may change from period to period based on future events or revisions of assumptions. These key assumptions are discussed in Note 9.
Insurance Contracts
Classification
Insurance contracts are comprised of insurance contracts issued, which are insurance and reinsurance or retrocession contracts that are issued by us, and reinsurance contracts held.

Insurance contracts issued are contracts under which we accept significant insurance risk from a policyholder by agreeing to compensate the policyholder if a specified uncertain future event adversely affects the policyholder. The presence of significant insurance risk in individual contracts is assessed by reviewing books of contracts with homogeneous risk features.

22 Sun Life Financial Inc. December 31, 2023 Notes to the Consolidated Financial Statements Reinsurance contracts held are insurance contracts under which we are the policyholder and have transferred insurance risk to the issuer of the contract, either the reinsurer or the retrocessionaire.


In the normal course of business, we use reinsurance to limit our exposure to large losses. We have a retention policy that requires that such arrangements be placed with well-established, highly-rated reinsurers.

Certain investment contracts contain discretionary participation features ("DPF"), whereby the policyholder has the right to receive, in addition to guaranteed amounts, potentially significant benefits based on returns on a specified pool of assets. For entities like us that issue insurance contracts, investment contracts with DPF are measured and reported as insurance contracts.

Judgment is required to determine the classification of a contract as an insurance contract, investment contract or a service contract. Contracts are classified at initial recognition. Once a contract is classified as an insurance contract, it remains an insurance contract until all rights and obligations are extinguished or the contract is derecognized.
Combination and Separation of Contracts
Derivatives embedded in insurance contracts are treated as separate contracts and measured at fair value with changes in fair value recognized in income unless the embedded derivative itself meets the definition of an insurance contract or when the risks and characteristics of the embedded derivative are closely related to those of the host contract. Embedded derivatives that are not separated are accounted for with the host insurance contract.

Investment components of insurance contracts are amounts we repay to a policyholder in all circumstances (e.g., cash surrender values). Investment components of insurance contracts are treated as separate investment contracts only if the investment component is not highly interrelated with the insurance component and a contract with equivalent terms could be sold separately in the same market. Investment components that are not separated are accounted for as non-distinct investment components of insurance contracts.

Service components of insurance contracts are treated as separate service contracts only if the service component is not highly interrelated with the insurance component and we provide no significant service in integrating the service component with the insurance component. Service components that are not separated are accounted for with insurance contracts.

Insurance components of insurance contracts are treated as separate contracts only if the insurance component constitutes a separate insurance contract (e.g., certain reinsurance treaties that transfer risk on different types of insurance contracts).

For insurance contracts where both parties to the contract have the practical ability to terminate the contract, the extension of the contract beyond the termination date is treated as a new and separate contract. This occurs for most group life and health insurance contracts every year, when we have the right to reprice the contract and the policyholder has the option to not renew the contract. In such instances, each renewal is considered a new and separate contract. This also applies for many reinsurance contracts held, where the reinsurer has the right to reprice new cessions and we have the right to cease ceding new contracts with a notice period. In such instances, the cessions within each notice period are considered a new and separate reinsurance contract held.
Measurement
Insurance contracts are measured in accordance with IFRS 17, using one of the following approaches:
•Variable fee approach ("VFA"): This approach applies to insurance contracts (excluding reinsurance contracts) with direct participation features, which are substantially investment-related service contracts where the policyholder is promised an investment return based on underlying items.
•Premium allocation approach ("PAA"): This is a simplified measurement approach and is applied to all insurance contracts that are eligible to use it, such as the majority of those in our group life and health businesses.
•General measurement approach ("GMA"): This approach applies to all insurance contracts not measured using the VFA or the PAA.

Reinsurance contracts held are measured in a manner consistent with the associated underlying insurance contracts and in accordance with the terms of each reinsurance contract held. Reinsurance contracts held cannot be measured using the VFA. The measurement of reinsurance contracts held includes a provision for the risk that the reinsurer will not honour its obligations under the contract.

The carrying value of insurance contracts comprises the liability for remaining coverage ("LRC") and the liability for incurred claims ("LIC"):
•The LRC is the measurement of our obligation to investigate and pay valid claims for insured events that have not yet occurred (i.e., the obligation that relates to the unexpired portion of the coverage period).
•The LIC is the measurement of our obligation to investigate and pay valid claims for insured events that have already occurred, including events that have occurred but for which claims have not been reported. For reinsurance contracts held, the LIC is an asset for incurred claims.
•For blocks of businesses acquired prior to January 1, 2023, any previously incurred claims where the amount paid to the beneficiary is subject to insurance risk are treated as LIC. For blocks of businesses acquired on or after January 1, 2023, such claims are treated as LRC.

Significant judgment is required in measuring assets or liabilities for insurance contracts, including the assumptions that are used for their measurement. Application of different assumptions may result in different measurement of the insurance contracts. Actual experience may differ from assumptions, and estimates may change from period to period based on future events or revisions of assumptions. Key assumptions and considerations in selecting these assumptions are discussed in Note 10. The sensitivity of the measurement of insurance contracts to changes in risk variables are discussed in Note 7.
Level of Aggregation
The unit of account for the measurement of insurance contracts is a group. Each insurance contract is assigned to a group at initial recognition and remains in that group until the insurance contract is derecognized.

Groups are subdivisions of portfolios. Portfolios are insurance contracts subject to similar risks and managed together and a portfolio is the level at which expenses are attributed and the level at which insurance contracts issued and reinsurance contracts held are presented.

Notes to the Consolidated Financial Statements     Sun Life Financial Inc. December 31, 2023 23


We have established portfolios in each reportable business segment, distinguished between:
•Insurance contracts issued and reinsurance contracts held;
•Group insurance contracts and individual insurance contracts;
•Participating insurance contracts and non-participating insurance contracts;
•Adjustable insurance contracts and non-adjustable insurance contracts;
•Traditional life insurance contracts and universal life insurance contracts; and
•Pass-through insurance contracts and discretionary crediting contracts.

Within each portfolio, separate groups are established by:
•Date of issue: To be in the same group, contracts must be issued within the same time period, and the period cannot be longer than one year; and
•Level of profitability: Insurance contracts are separated into groups of contracts that are onerous at initial recognition, contracts that do not have a significant possibility of becoming onerous subsequently, and other contracts. The level of profitability for an insurance contract is based on the CSM at initial recognition of the contract (as described below in Initial Measurement).

We do not establish additional groups beyond the minimum required except for some portfolios of reinsurance contracts held where grouping is established to line up with the grouping of the underlying insurance contracts issued.
Initial Measurement
Groups of insurance contracts are recognized and measured as the total of the following measurement components:
•Fulfilment cash flows ("FCF"), which is comprised of:
•The present value of future cash flows (including the provisions for financial risk),
•The risk adjustment for non-financial risk; and
•A CSM, representing the unearned profit that will be recognized in income as insurance contract services are provided.

These measurement components apply to groups of insurance contracts measured using the GMA and the VFA. Under the PAA, which is a simplified measurement approach, insurance contracts are measured based on unearned profits and do not include a CSM.
GMA or VFA
Using the GMA or VFA, a group of insurance contracts is measured as the total of the three measurement components, as described above.

Estimates of the present value of future cash flows are explicit and current, and consider all reasonable and supportable information available at the reporting date without undue cost or effort. The portion of the present value of future cash flows related to financial risk variables is consistent with observable market prices and, where necessary, considers a range of scenarios that provides a good representation of possible outcomes. The cash flows for each scenario are probability-weighted and discounted using current assumptions.

The risk adjustment for non-financial risk represents the compensation required for uncertainty related to non-financial risk (mortality, morbidity, surrender and expenses, etc.). The risk adjustment is reduced as the non-financial risks of our insurance contracts diminish over time ("release of risk adjustment").

The CSM at the initial recognition of an insurance contract issued is the amount that fully offsets the FCF at initial recognition, and represents unearned profits on new business that are deferred and amortized into income as insurance contract services are provided. For insurance contracts issued that are not profitable at initial recognition ("onerous insurance contracts"), a CSM is not established and losses are recognized in income immediately.

For reinsurance contracts held, there is no restriction on the CSM based on profitability at initial recognition, and any losses are deferred in the same manner as profits. In addition, the CSM for reinsurance contracts held can be adjusted to offset any gains or losses on the groups of underlying direct contracts that would have gone through CSM if the group of underlying direct contracts had a CSM balance.

For onerous insurance contracts, the loss recognized in the Consolidated Statements of Operations at initial recognition is added to the loss component of the group to which the contract is assigned. The loss component is a notional portion of the LRC that represents the amount of loss that can be reversed by future profit before a CSM is re-established for the group. For groups of reinsurance contracts held for which the CSM has been adjusted to offset gains and losses on groups of underlying direct contracts without a CSM, a loss recovery component is established.
PAA
For groups of insurance contracts using the PAA, there is no liability established at initial recognition, unless factors indicate that the group is onerous, in which case the group is initially recognized at the amount it is onerous, and a loss of that amount is recognized in the Consolidated Statements of Operations and becomes the loss component of the group. For groups using the PAA, insurance acquisition cash flows are recognized in the Consolidated Statements of Operations when incurred, rather than including such expenses in the measurement of LRC.
Subsequent Measurement
The subsequent measurement of FCF uses the same approach as described above for initial measurement, but with current inputs for each subsequent reporting date.

For contracts measured using the PAA, the LRC subsequent to initial recognition is the amount of unearned revenue and the remaining loss component for any groups that are onerous. We do not adjust the LRC to reflect the time value of money and the effects of financial risk when we expect the time between providing coverage and the related premiums to be no more than one year. We do not adjust the LIC to reflect the time value of money and the effects of financial risk when we expect the claims to be fully paid within one year of the insured event occurring.

For contracts measured using the GMA or VFA, the measurement of CSM subsequent to initial recognition is described below.

24 Sun Life Financial Inc. December 31, 2023 Notes to the Consolidated Financial Statements For groups of insurance contracts issued using the GMA, the CSM at the end of a reporting period is measured as the CSM at the beginning of the reporting period, adjusted for:


•The effect of any new contracts added to the group;
•Interest accretion on the carrying amount of the CSM;
•The change in FCF relating to future service, except to the extent that increases exceed the carrying amount of the CSM (giving rise to a loss) or decreases are allocated to the loss component of the LRC (reversing a prior loss);
•The effect of any currency exchange differences on the CSM; and
•The amount recognized as Insurance revenue due to the performance of insurance contract services in the period ("CSM amortization").

For groups of insurance contracts issued using the VFA, the CSM at the end of a reporting period is measured as the CSM at the beginning of the reporting period, adjusted for:
•The effect of any new contracts added to the group;
•The change in the entity's share of the fair value of underlying items, except to the extent a decrease exceeds the carrying amount of the CSM (giving rise to a loss) or an increase reverses a prior loss, or that risk mitigation applies (see below);
•The change in FCF relating to future service, except to the extent that increases exceed the carrying amount of the CSM (giving rise to a loss) or decreases are allocated to the loss component of the LRC (reversing a prior loss), or that risk mitigation applies (see below);
•The effect of any currency exchange differences on the CSM; and
•CSM amortization.

The risk mitigation option is provided to avoid accounting mismatches that would otherwise occur when the financial risk of a group of insurance contracts is mitigated outside the underlying items of the group. For insurance contracts issued using the VFA, changes related to financial risk adjust the CSM, but offsetting changes from risk mitigation (e.g., derivatives) may go through income. The risk mitigation option allows for a change that would otherwise adjust CSM to be recognized in income instead, to avoid such a mismatch. We apply the risk mitigation option where applicable to reduce accounting mismatches. The effect on CSM of applying the risk mitigation option is disclosed in more detail in Note 5.C.

For groups of reinsurance contracts held, the CSM at the end of a reporting period is measured as the CSM at the start of the reporting period, adjusted for:
•The effect of any new contracts added to the group;
•Interest accretion on the carrying amount of the CSM;
•Income recognized in the reporting period as a result of gains or losses recognized to offset gains or losses on groups of underlying direct contracts with no CSM;
•Reversals of a loss-recovery component to the extent those reversals are not changes in the FCF of the group of reinsurance contracts held;
•The change in FCF relating to future service, unless the change offsets a gain or loss on groups of underlying direct contracts with no CSM or the change is related to groups of onerous insurance contracts using the PAA;
•The effect of any currency exchange differences on the CSM; and
•The amount recognized in income due to services received in the period.

We have not changed the accounting estimates made in previous interim financial statements in the preparation of these Consolidated Financial Statements. In particular, the CSM at the end of each reporting period is the CSM at the beginning of the reporting period adjusted as described above, rather than the CSM at the beginning of the calendar year adjusted as described above.
Presentation on the Consolidated Financial Statements
The carrying value of portfolios of insurance contracts issued and reinsurance contracts held that are in an asset position are presented as Insurance contract assets and Reinsurance contract held assets in the Consolidated Statements of Financial Position, while the carrying value of portfolios of insurance contracts issued and reinsurance contracts held that are liabilities are presented as Insurance Contract liabilities excluding those for account of segregated fund holders and Reinsurance contract held liabilities. Assets for insurance acquisition cash flows incurred before initial recognition of the contracts to which they are attributable are included in the carrying value of the portfolio associated with those contracts.

Amounts related to insurance contracts that impact income are included in the Net insurance service result of the Consolidated Statements of Operations and the Insurance finance income (expenses) line in the Net investment result section. Results in those sections are presented separately for insurance contracts issued and reinsurance contracts held. We have chosen to disaggregate changes in the RA between the Insurance revenue line in Net insurance service result, and the Insurance finance income (expenses) line in Net investment result.
Net insurance service result
Insurance revenue is recognized as insurance contract services are provided for groups of insurance contracts. For insurance contracts issued that are measured using the GMA or the VFA, Insurance revenue includes the following services for which consideration in the form of premiums, net of premium taxes, is expected to be received:
•Expected claims and other expenses directly attributable to fulfilling insurance contracts, measured at the amounts expected at the beginning of the period, and excluding investment components and amounts allocated to the loss component;
•Release of the RA for the period, excluding amounts allocated to the loss component and amounts related to changes in the time value of money, which are recognized in Insurance finance income (expenses);
•CSM amortization to reflect services provided in the period, measured using the coverage units for the reporting period as a proportion of total coverage units (additional detail on coverage units is provided in Note 10);
•Amortization of insurance acquisition cash flows;
•Premium experience adjustments that relate to current or past service; and
•Expected amounts related to income taxes specifically chargeable to the policyholder.

Amortization of insurance acquisition cash flows in Insurance revenue is an allocation of the portion of the premiums that relates to the recovery of insurance acquisition cash flows, determined in a systematic way based on the passage of time. An equal and offsetting amount is included in Insurance service expenses.
Notes to the Consolidated Financial Statements     Sun Life Financial Inc. December 31, 2023 25



For insurance contracts issued measured using the PAA, expected premium receipts (net of premium taxes and excluding investment components) are recognized as revenue, generally based on the passage of time.

Insurance service expenses include:
•Claims incurred in the period (excluding investment components and amounts allocated to the loss component);
•Expenses incurred that are directly attributable to fulfilling the insurance contracts;
•Losses on onerous contracts and reversals of those losses;
•Changes related to past service (e.g., changes in the LIC in periods subsequent to the claim being incurred);
•Amortization of insurance acquisition cash flows;
•Insurance acquisition cash flows expensed as incurred related to PAA contracts; and
•Impairment and reversals of impairment of assets for insurance acquisition cash flows.

For reinsurance contracts held, we have elected to present income and expenses arising from these contracts as a single amount in the Reinsurance contract held net income (expense) line on the Consolidated Statements of Operations. This amount includes an allocation of reinsurance premiums, amounts recovered from reinsurers, and changes in the risk of non-performance by the reinsurer. Allocations of reinsurance premiums are recognized as services are received for the reinsurance contract held.

For reinsurance contracts held measured using the GMA, the services received for which consideration is paid include:
•Expected recoveries and expenses, excluding amounts that are paid regardless of claims;
•Release of the RA for the period;
•CSM recognized for services received; and
•Premium experience adjustments that relate to current or past service.

For reinsurance contracts held measured using the PAA, expected premium payments (net of premium taxes and excluding amounts that are paid regardless of claims) are recognized as an allocation of reinsurance premiums based on the passage of time. Amounts recovered from reinsurers includes incurred claims (excluding amounts that are paid regardless of claims) and expenses, loss recoveries and reversals of loss recoveries, and changes related to past service (e.g., changes in the asset for incurred claims in periods subsequent to the claim being incurred).
Insurance finance income (expenses)
Changes in the carrying value of insurance contracts issued not measured using the VFA and reinsurance contracts held that are due to changes in the time value of money and in financial risk are recognized in the Insurance finance income (expenses) line on the Consolidated Statements of Operations. For insurance contracts issued measured using the VFA, Insurance finance income (expenses) includes changes in the fair value of underlying items and changes not recognized in the CSM when the risk mitigation option is applied. We have elected to recognize all insurance finance income (expenses) in the Consolidated Statements of Operations and not in OCI. Insurance finance income (expense) for insurance contracts for account of segregated fund holders is discussed in the Segregated Funds section of this Note.
Derecognition and Modification
Insurance contracts are derecognized when the obligations in the contract expire, are discharged or cancelled, or when it is modified and the modification is substantial, such as when the modification results in a change in the measurement approach. When a contract modification results in derecognition, the original contract is derecognized and the modified contract is recognized as a new contract. Modifications that do not result in derecognition are treated as changes in FCF.
Segregated Funds
Segregated funds are products where the benefit amount is directly linked to the fair value of the investments held in the particular segregated fund. Although the underlying assets are registered in our name and the segregated fund contract holder has no direct access to the specific assets, the contractual arrangements are such that the segregated fund policyholders bear the risks and rewards of the fund’s investment performance. In addition, certain segregated funds contracts include guarantees from us. Segregated fund contracts are classified as insurance contracts or investment contracts following the classification criteria described in the Insurance Contracts section of this Note and Note 10.
Investments for Account of Segregated Fund Holders
Investments for account of segregated fund holders are recorded separately from the Total general fund assets in our Consolidated Statements of Financial Position and are carried at fair value. Fair values are determined using quoted market values or, where quoted market values are not available, estimated fair values as determined by us. Investments for account of segregated fund holders includes investments for contracts that are classified as insurance contracts and investments for contracts that are classified as investment contracts. Unrealized gains and losses and other investment income from investments for account of segregated fund holders classified as insurance contracts is reported as Net investment income (loss) within the Net investment result for insurance contracts for account of segregated fund holders in the Consolidated Statements of Operations. Such investment income (loss) will be offset by the corresponding increase in the insurance contract liabilities for account of segregated fund holders. Changes in the fair value of the investments for account of segregated fund holders classified as investment contracts are recorded in net realized and unrealized gains (losses) within the segregated fund and are not recorded in our Consolidated Statements of Operations.
Insurance Contract Liabilities for Account of Segregated Fund Holders
Segregated fund products classified as insurance contracts are contracts with direct participation features and are therefore measured using the VFA described in the Insurance contracts section of this Note. Insurance contract liabilities for these contracts are presented as two separate lines on the Consolidated Statements of Financial Position: Insurance contract liabilities excluding those for account of segregated fund holders, and Insurance contract liabilities for account of segregated fund holders. The Insurance contract liabilities for account of segregated fund holders represents the obligation to pay the policyholder an amount equal to the fair value of the underlying items. Changes in this obligation due to changes in fair value of the underlying items are recognized as Insurance finance income or expenses in the Net investment result for insurance contracts for account of segregated fund holders in the Consolidated Statements of Operations. Such
26 Sun Life Financial Inc. December 31, 2023 Notes to the Consolidated Financial Statements insurance finance income or expenses will be offset by the corresponding increase in Investments for account of segregated fund holders.


Deposits into and payments from the segregated funds are investment components and thus excluded from insurance revenue and insurance service expenses. The Insurance contract liabilities excluding those for account of segregated fund holders on the Consolidated Statements of Financial Position includes the remaining insurance contract liabilities for these contracts, which comprises the provision for guarantees, future expenses (less future fees), the RA and the CSM. Revenue and expenses related to these items are included in the Insurance service result on the Consolidated Statements of Operations.
Investment Contract Liabilities for Account of Segregated Fund Holders
Investment contract liabilities for account of segregated fund holders are recorded separately from the Total general fund liabilities in our Consolidated Statements of Financial Position. The liabilities reported as Investment contracts for account of segregated fund holders are measured at the aggregate of the policyholder account balances. We derive fee income from segregated funds classified as investment contracts, which is included in Fee income in our Consolidated Statements of Operations. Deposits to segregated funds and payments made from segregated funds are reflected as increases or decreases in Investment contract liabilities for account of segregated fund holders and Investments for account of segregated fund holders and are not reported as revenues or expenses in our Consolidated Statements of Operations.
Financial Liabilities
Classification and initial measurement
Our financial liabilities are classified and measured at amortized cost, except for financial guarantees, derivative liabilities, and liabilities related to CLOs. Financial guarantees, derivative liabilities, and liabilities related to CLOs are classified as FVTPL. For further details on the liabilities related to CLOs, refer to Note 5.A.i. We may also designate certain investment contracts liabilities and third-party interests in consolidated funds at FVTPL on initial recognition, and once designated, the designation is irrevocable. Financial liabilities are designated at FVTPL if doing so either eliminates or significantly reduces accounting mismatch with the supporting assets or that the liabilities and supporting assets are managed together and their performance is evaluated on a fair value basis. Liabilities related to CLOs are designated at FVTPL on initial recognition as doing so either eliminates or significantly reduces an accounting mismatch with the supporting assets. The FVTPL designation is available only for those financial liabilities for which a reliable estimate of fair value can be obtained. All other investment contracts are measured at amortized cost using the effective interest rate method.
Subsequent measurement
Policies applicable beginning January 1, 2023
Financial liabilities classified or designated at FVTPL are measured at fair value. Any interest expenses, foreign exchange gains (losses), and fair value changes that are not due to changes in own credit risk are recognized in Net investment income (loss) in the Consolidated Statements of Operations, unless they arise from derivatives designated as hedging instruments in net investment hedges. For financial liabilities designated at FVTPL, fair value changes attributable to changes in our own credit risk are recorded in OCI, and are not reclassified subsequently to Net investment income (loss) in the Consolidated Statements of Operations.

Financial liabilities at amortized cost are measured at fair value less transaction costs at initial recognition, and subsequently at amortized cost using the effective interest rate method. Interest expense and foreign exchange gains (losses) are recorded in Net investment income (loss) in the Consolidated Statements of Operations.

Policies applicable prior to January 1, 2023
Financial liabilities are classified or designated at FVTPL with the total amount of changes in fair value recognized in profit or loss.
Derecognition
We generally derecognize a financial liability when the contractual obligations expire or are discharged or cancelled. We also derecognize a financial liability when the terms are modified and the cash flows of the modified liability are substantially different, in which case a new financial liability based on the modified terms is recognized at fair value. On derecognition of a financial liability, the difference between the carrying amount extinguished and the consideration paid (including any new non-cash assets transferred or liabilities assumed) is recognized in the Consolidated Statements of Operations.
Investment Contract Liabilities
Policies applicable beginning January 1, 2023
Contracts issued by us that do not transfer significant insurance risk, but do transfer financial risk from the policyholder to us, are financial liabilities and are accounted for as investment contracts, unless they have DPF, in which case they are accounted for as insurance contracts (See Insurance Contracts). Distinct service components of investment contracts are treated as service contracts (See Service Contracts and Fee Income).

Investment contract liabilities without DPF are initially recognized at fair value, less transaction costs directly attributable to the issue of the contract, and are subsequently held at amortized cost using the effective interest rate method. Amortization is recorded as a Decrease (increase) in investment contract liabilities in our Consolidated Statements of Operations. Deposits collected from and payments made to contract holders are recorded as changes in our Investment contract liabilities balance in the Consolidated Statements of Financial Position. Investment contract liabilities are derecognized when the obligation of the contract is discharged, cancelled or expired. Investment contract liabilities without DPF include term certain payout annuities in Canada, accumulation annuities and guaranteed investment contracts in Canada, unit-linked products issued in Hong Kong, and non-unit linked pensions contracts issued in Hong Kong.

As discussed in the Segregated Funds section of this Note, investment contracts under which the policyholder bears the risks associated with the underlying investments are classified as Investment contracts for account of segregated fund holders in the Consolidated Statements of Financial Position.

Notes to the Consolidated Financial Statements     Sun Life Financial Inc. December 31, 2023 27


Policies applicable prior to January 1, 2023
Liabilities for investment contracts without DPF are measured at FVTPL or amortized cost. Contract recorded at FVTPL are measured at fair value at inception and each subsequent reporting period. At each subsequent period, changes in fair value of investment contract liabilities recorded at FVTPL are recorded as an Increase in investment contract liabilities in our Consolidated Statements of Operations. Investment contract liabilities without DPF include term certain payout annuities in Canada, accumulation annuities and guaranteed investment contracts in Canada, unit-linked products issued in the UK and Hong Kong, and non-unit linked pensions contracts issued in the UK and Hong Kong.
Obligations for Securities Borrowing
The obligation for securities borrowing represents our commitment to deliver securities under the short sale program. Under the program, we short sell the securities that we borrowed from a third party. The obligation to return the securities is not recognized in the Consolidated Statements of Financial Position until they are sold, and the risks and rewards of ownership have been transferred. Upon recognition, they are measured at fair value. The securities borrowings are returnable to the lender upon demand or at our discretion.
Other Liabilities
Other liabilities, which are measured at amortized cost, include accounts payable, credit facilities, repurchase agreements, accrued expenses and taxes, senior financing, provisions, lessee’s lease liabilities and a deferred payment liability. Liabilities for provisions, other than those reported with insurance contract liabilities and investment contract liabilities, are recognized for present legal or constructive obligations as a result of a past event if it is probable that they will result in an outflow of economic resources and the amount can be reliably estimated. The amounts recognized for these provisions are the best estimates of the expenditures required to settle the present obligations or to transfer them to a third party at the reporting date, considering all the inherent risks and uncertainties, as well as the time value of money. These provisions are reviewed as relevant facts and circumstances change.

Lease liabilities are measured as described in the Leases Section of this Note.

Other financial liabilities are measured at amortized cost. For put option liabilities, upon initial recognition, the present value is calculated using our incremental borrowing rate and subsequent revisions to the expected timing or amount of cash flows payable as well as interest expense will be recognized in the Consolidated Statements of Operations.
Senior Debentures and Subordinated Debt
Senior debentures and subordinated debt liabilities are recorded at amortized cost using the effective interest rate method. Transaction costs are recorded as part of the liability and are recognized in income using the effective interest rate method. These liabilities are derecognized when the obligation of the contract is discharged, cancelled or expired.
Service Contracts and Fee Income
Contracts issued by us that do not transfer significant insurance risk and do not transfer financial risk from the customer to us, including contracts for investment management service, are classified as service contracts. Distinct service components of insurance and investment contracts are also accounted for as service contracts.

Fees earned from these contracts are recognized and included in Fee income in our Consolidated Statements of Operations. Fee income from service contracts represents fees associated with contracts with customers and includes distribution fees, fund management and other asset-based fees, and administrative services and other fees. Distribution fees includes fees earned from the distribution of investment products and other intermediary activities. Fund management and other asset-based fees includes fees earned from investment management services. Administrative services and other fees includes fees earned from contract administration and other management services. Fee income from service contracts is typically recognized as revenue when services are rendered at either a point in time or over time. The majority of fee income from service contracts is comprised of variable consideration that is based on a percentage of assets under management or another variable metric and is recognized as revenue when it is highly probable that a significant reversal in the amount of the revenue recognized will not occur.

Deferred acquisition costs arising from service contracts or investment contracts are amortized over the expected life of the contracts based on the future expected fees. Where the cost of meeting the obligations of the contract exceeds the economic benefits expected to be received under it, a provision is recognized in Other liabilities in our Consolidated Statements of Financial Position.
Income Taxes
Current income tax assets and liabilities for the current and prior periods are measured at the amount expected to be recovered from or paid to the taxation authorities. Deferred income tax is provided using the liability method on temporary differences at the reporting date between the tax bases of assets and liabilities and their carrying amounts for financial reporting purposes. Current and deferred income tax relating to items recognized in the current or previous period in OCI or directly in equity is accordingly recognized in OCI or equity and not in our Consolidated Statements of Operations. Interest and penalties payable to taxation authorities are recorded in Interest expense and Operating expenses, respectively, in our Consolidated Statements of Operations.

Deferred income tax assets and liabilities are calculated based on income tax rates and laws that are expected to apply when the liability is settled or the asset is realized, which are normally those enacted or considered substantively enacted at the reporting date. Deferred income tax assets are recognized for all deductible temporary differences, carry forward of unused tax credits and unused tax losses to the extent that future taxable profit is expected to be available against which these assets can be utilized. At each reporting period, we assess all available evidence, both positive and negative, to determine the amount of deferred income tax assets to be recognized. The recognition of deferred income tax assets requires estimates and significant judgment about future events, such as projections of future taxable profits, based on the information available at the reporting date.

The determination of the required provision for current and deferred income taxes requires that we interpret tax legislation in the jurisdictions in which we operate. For each reporting period, our income tax provision reflects our best estimate, based on the information available at the reporting date, of tax positions that are under audit or appeal by relevant tax authorities. To the extent that our estimate of
28 Sun Life Financial Inc. December 31, 2023 Notes to the Consolidated Financial Statements tax positions or the timing of realization of deferred income tax assets or liabilities are not as expected, the provision for income taxes may increase or decrease in the future to reflect the actual experience.



Deferred income tax is provided on temporary differences arising on investments in subsidiaries, joint ventures and associates, except where we control the timing of the reversal of the temporary difference and it is apparent that the temporary difference will not reverse in the foreseeable future. No deferred income tax asset or liability is recognized in relation to temporary differences that arise from the initial recognition of an asset or liability in a transaction that is not a business combination and, at the time of the transaction, did not affect either the accounting profit or taxable profit or loss. Deferred income tax assets and deferred income tax liabilities are offset if a legally enforceable right exists to set off current tax assets against current tax liabilities, the deferred income taxes relate to the same taxable entity and the same taxation authority and we intend either to settle on a net basis, or to realize the asset and settle the liability simultaneously.
Pension Plans and Other Post-Retirement Benefits
For defined benefit plans, the present value of the defined benefit obligation is calculated by independent actuaries using the projected unit credit method, and actuarial assumptions that represent best estimates of future variables that will affect the ultimate cost of these obligations. The discount rate used for our material defined benefit plans is determined with reference to market yields of high-quality corporate bonds that are denominated in the same currency in which the benefits will be paid, and that have terms to maturity approximating the terms of obligations. Plan assets are measured at fair value and are held in separate trustee administered funds or as qualifying insurance contracts. The difference between the fair value of the plan assets and the present value of the defined benefit obligation is recognized on the Consolidated Statements of Financial Position as an asset or liability in Other assets or Other liabilities, respectively.

Costs charged to our Consolidated Statements of Operations include current service cost, any past service costs, any gains or losses from curtailments or settlements, and interest on the net defined benefit liability (asset). Remeasurement of the net defined benefit liability (asset), which includes the impact of changes to the actuarial assumptions underlying the liability calculations, liability experience gains or losses, the difference between the return on plan assets and the amount included in the interest on the net defined benefit liability (asset), is reflected immediately in OCI. The calculation of the defined benefit expenses and obligations requires judgment as the recognition is dependent on various actuarial assumptions such as discount rates, health care cost trend rates and projected compensation increases. These key assumptions are discussed in Note 24.
Dividends
Dividends payable to holders of shares of SLF Inc. are recognized in the period in which they are authorized or approved. Dividends that have been reinvested in additional common shares under the Dividend Reinvestment and Share Purchase Plan ("DRIP") are also reflected as dividends within retained earnings. Where SLF Inc. has issued common shares from treasury under the DRIP, the additional shares have been reflected in common shares.
Share-Based Payments
Stock options of SLF Inc. granted to employees are accounted for as equity-settled share-based payment transactions. The total compensation expense for stock options is computed based on the fair value of the stock option at the date of grant and the estimated number of options expected to vest at the end of the vesting period. The expense is recognized over the vesting period as compensation expense in Operating expenses in our Consolidated Statements of Operations, with an offset to contributed surplus in our Consolidated Statements of Changes in Equity. When options are exercised, new common shares are issued, contributed surplus is reversed and the common shares issued are credited to common shares in our Consolidated Statements of Changes in Equity.

Other share-based payment plans based on the value of SLF Inc.’s common shares are accounted for as cash-settled share-based payment transactions. The total liabilities for these plans are computed based on the estimated number of awards expected to vest at the end of the vesting period. The liabilities are recomputed at the end of each reporting period and are measured at the fair value of the award at that reporting date. The liabilities are accrued and expensed on a straight-line basis over the vesting periods. The liabilities are settled in cash at the end of the vesting period.

Share-based payment awards within MFS Investment Management ("MFS"), which are based on their own shares, are accounted for as cash-settled share-based payment awards. The vested and unvested awards, as well as the shares that have been issued under these plans, are recognized as liabilities because MFS has a practice of purchasing the issued shares from employees after a specified holding period. The total liabilities for these plans are computed based on the estimated number of awards expected to vest at the end of the vesting period. The liabilities are accrued over the vesting period and are measured at fair value at each reporting period with the change in fair value recognized as compensation expense in Operating expenses in our Consolidated Statements of Operations. The liabilities are settled in cash when the shares are purchased from the employees.
Basic and Diluted Earnings Per Share ("EPS")
Basic EPS is calculated by dividing the common shareholders’ net income by the weighted average number of common shares issued and outstanding.

Diluted EPS adjusts common shareholders’ net income and the weighted average number of common shares for the effects of all dilutive potential common shares under the assumption that convertible instruments are converted and that outstanding options are exercised. Diluted EPS is calculated by dividing the adjusted common shareholders’ net income by the adjusted weighted average number of common shares outstanding. For convertible instruments, common shareholders’ net income is increased by the after-tax expense on the convertible instrument while the weighted average common shares are increased by the number of common shares that would be issued at conversion. For stock options, it is assumed that the proceeds from the exercise of options whose exercise price is less than the average market price of common shares during the period are used to repurchase common shares at the average market price for the period. The difference between the number of common shares issued for the exercise of the dilutive options and the number of common shares that would have been repurchased at the average market price of the common shares during the period is adjusted to the weighted average number of common shares outstanding.

2. Changes in Accounting Policies
2.A New and Amended International Financial Reporting Standards Adopted in 2023
We adopted the following new and amended IFRS on January 1, 2023.
2.A.i IFRS 17
Summary
In May 2017, the IASB issued IFRS 17, with an amendment issued in June 2020 to defer the effective date of IFRS 17 to annual periods beginning on or after January 1, 2023. This standard is to be applied using a retrospective approach, with at least one year of comparative results provided. If retrospective application to a group of insurance contracts is impracticable, a modified retrospective or fair value approach may be used. IFRS 17 replaces IFRS 4 Insurance Contracts ("IFRS 4") and impacts how we recognize, measure, present, and disclose our insurance contracts in our Consolidated Financial Statements.

IFRS 17 and IFRS 9 were effective for us beginning January 1, 2023. Restated comparative period results have been provided for IFRS 17. As permitted by IFRS 9, we elected not to restate comparative period results, and as permitted by IFRS 17, we have elected to present comparative information on financial assets as if IFRS 9 were applicable during the comparative period.

For initial measurement of insurance contracts at the transition date of January 1, 2022, we have elected to use the fair value approach for all groups for which the retrospective approach is impracticable. For more information on the application of the fair value approach at transition, see the Fair value measurement section below.

IFRS 17 establishes principles for the recognition, measurement, presentation, and disclosure of insurance contracts. The key principles of IFRS 17 are as follows:
•Insurance contracts are those under which an entity accepts significant insurance risk from another party ("policyholder") by agreeing to compensate the policyholder if a specified uncertain future event ("insured event") adversely affects the policyholder.
•Insurance contracts issued and reinsurance contracts held are divided into groups that will be separately recognized and measured.
•Groups of insurance contracts are recognized and measured as the total of the following measurement components: a) the present value of future cash flows; b) a risk adjustment for non-financial risk ("RA"); and c) the Contractual Service Margin ("CSM"), an amount that represents the unearned profit of the group of contracts. These measurement components apply to groups of insurance contracts measured using the GMA and the VFA. The VFA applies to insurance contracts issued with direct participation features, which are substantially investment-related service contracts under which the policyholder is promised an investment return based on underlying items, such as segregated funds and certain participating insurance contracts. For short duration contracts, such as most of our group life and health business, a simplified measurement approach (PAA) is applied. Under the PAA, insurance contracts are measured based on unearned profits and do not include a CSM.
•The profit from a group of insurance contracts is recognized into income over the period that insurance contract services are provided and as the non-financial risks related to providing the insurance contracts diminish.
•Insurance revenue, insurance service expenses and insurance finance income or expenses are presented separately.
Significant Differences between IFRS 17 and IFRS 4
The following section describes the most significant differences between IFRS 17 and the accounting policies applied under IFRS 4.
Scope
There is no substantial change in IFRS 17 compared to IFRS 4 with regards to which contracts fall within the scope of the standard. However, we have updated the accounting policy for classification that was adopted on the transition to IFRS 4 in 2011 to ensure consistency with the IFRS 17 definition of insurance contracts.

Under IFRS 17, an insurance contract is defined as a contract under which the issuer accepts significant insurance risk from the policyholder by agreeing to compensate the policyholder if an insured event adversely affects the policyholder. In assessing whether "significant" insurance risk exists, certain contracts that were classified as insurance contracts under IFRS 4 were reclassified as investment contracts under IFRS 17. Such changes in classification were limited to certain deferred annuity products where the insurance risk is limited to the right to annuitize the maturity benefit, which fell short of the threshold for "significant" insurance risk.

Furthermore, IFRS 17 includes new requirements for the separation of distinct investment components and distinct goods or non-insurance service components of insurance contracts. At transition to IFRS 17, there were no distinct investment components and only immaterial distinct service components in our insurance contracts.

Unlike IFRS 4, IFRS 17 requires reinsurance contracts held to be measured separately from the underlying direct contracts. A reinsurance contract is an insurance contract issued by the reinsurer to compensate another entity for claims arising from one or more insurance contracts issued by that other entity ("underlying contracts").

Only contracts that transfer insurance risk to the reinsurer are considered reinsurance contracts held from the ceding entity’s point of view. We have reinsurance treaties that transfer only non-insurance risks to the reinsurer, however these are not considered reinsurance contracts held in scope of IFRS 17, nor were they in scope of IFRS 4. Rather, they are treated as insurance contracts purchased.

Reinsurance treaties that are part of the underlying items of participating insurance contracts (i.e., where all the cash flows of the reinsurance treaty are fully passed through to the participating insurance policyholders) are measured and reported separately.

Investment contracts with DPF are in scope of IFRS 17 and were in scope of IFRS 4. However, such contracts were reported with other investment contracts under IFRS 4, and are reported with insurance contracts under IFRS 17.
30 Sun Life Financial Inc. December 31, 2023 Notes to the Consolidated Financial Statements The measurement of insurance contracts under IFRS 17 differs from the Canadian Asset Liability Method ("CALM") previously applied under IFRS 4.


Measurement
The most significant differences by measurement component are as follows:

Present value of future cash flows:
•The discount rates used to present value future cash flows under IFRS 17 are based on the characteristics of the insurance contracts. Under IFRS 4, the CALM is used to determine actuarial liabilities based on the portfolio of assets currently supporting the insurance contract liabilities and reinvestment assumptions.
•Estimates under IFRS 17 include the current market view of the cost of financial guarantees, which requires a valuation consistent with market option prices. Under IFRS 4, the cost of financial guarantees is based on the amount required to fulfill the obligation but not directly linked to market option prices.
•Expense cash flows under IFRS 17 are limited to those directly attributable to fulfilment of the obligations under insurance contracts.
•Future income taxes are excluded from future cash flows under IFRS 17.

RA:
•Measures the compensation required for uncertainty related to non-financial risk, such as mortality, morbidity, surrender and expenses under IFRS 17.
•Provisions for uncertainty related to financial risk are implicitly included in the present value of future cash flows under IFRS 17.
•No amount is provided for asset-liability mismatch risk under IFRS 17.
•Under IFRS 4, amounts provided for the risks listed above are reflected in a provision for adverse deviations included in insurance contract liabilities.

CSM:
•This is a new component of liabilities and necessitates the "grouping" of insurance contracts, which is not required under IFRS 4.
•The CSM represents unearned profits, as discussed above.

The measurement approaches under IFRS 17 and IFRS 4 are similar for insurance contracts measured using the PAA. Differences arise mainly in the measurement of the LIC, where the discount rate and risk adjustment for non-financial risk changes noted above apply.
Presentation
IFRS 17 requires that portfolios of insurance contracts that are in an asset position be presented separately from portfolios of insurance contracts that are in a liability position in the Consolidated Statements of Financial Position. Also, portfolios of insurance contracts issued must be presented separately from portfolios of reinsurance contracts held. Previously, insurance contracts issued were presented only as liabilities and reinsurance contracts held were presented only as assets. Certain balances, such as policy loans and outstanding and prepaid premiums, that were previously presented separately or included in Other assets and Other liabilities are now included in the assets or liabilities for insurance contracts issued or reinsurance contracts held.

The presentation of income from insurance contracts on the Consolidated Statements of Operations has changed significantly for IFRS 17. Prior to IFRS 17, insurance related income was presented separately in the lines Gross premiums, Ceded premiums, Gross claims and benefits paid, Reinsurance expenses (recoveries), Increase (decrease) in insurance contract liabilities, and Decrease (increase) in reinsurance assets. The line Operating expenses, commissions and premium taxes included all expenses, reflecting those from both insurance and non-insurance contracts.

Under IFRS 17, insurance-related income is presented in the Insurance service result section and the Insurance finance income (expenses) line in the Investment result section. Amounts are presented separately for insurance contracts issued and reinsurance contracts held. The Insurance service expenses line includes amounts previously reported as Gross claims and benefits paid, with the exclusion of repayments of investment components, which are amounts that are returned to policyholders under all circumstances. Directly attributable expenses are also presented as Insurance service expenses. Income or expense from reinsurance contracts held is now presented as one line, which includes an allocation of reinsurance premiums paid and amounts recovered from reinsurers.

For insurance contracts measured using the GMA or VFA, premiums are no longer reported as revenue or recognized in income when received. Insurance revenue in a reporting period is comprised of the portion of premiums that cover expected claims and directly attributable expenses in the period, as well as the release of RA and the amortization of CSM for the period. Insurance revenue excludes the portion of premiums that cover repayment of investment components.

Fee income excludes income from insurance contracts as any fees earned would be recognized in Insurance contract revenue. Similarly, the Operating expenses and commissions line excludes expenses that are directly attributable to issuing or fulfilling insurance contracts as these expenses, as well as premium taxes paid, are included in the Insurance service result section.
Transition Impacts
Transition Method
The retrospective application of IFRS 17 at the transition date of January 1, 2022, was implemented using the fair value approach where a full retrospective approach was impracticable. The full retrospective approach was deemed impracticable for all groups of insurance contracts measured using the GMA or VFA, because estimates required information that was either not available or would not have been available in a usable form in prior periods. For groups of insurance contracts measured using the PAA, we applied full retrospective measurement at transition.

Under the fair value approach, the CSM at transition for a group of insurance contracts is equal to the fair value of the group of insurance contracts less the FCF measured using IFRS 17. The fair value of a group of insurance contracts is the amount that a market participant would require to take over the obligations of the group of insurance contracts.
Notes to the Consolidated Financial Statements     Sun Life Financial Inc. December 31, 2023 31


Transition Grouping
As permitted under IFRS 17 when using the fair value approach, groups of insurance contracts at transition were formed according to the IFRS 17 grouping requirements, but without the restriction that groups should not contain contracts that are issued more than one year apart. Also, given the definition of fair value, all insurance contracts issued in a portfolio were in the same profitability group. Therefore, there was only one group for each portfolio of insurance contracts issued at transition. Portfolios of reinsurance contracts held at transition were grouped according to the grouping of the direct underlying contracts.
Fair Value Measurement
The fair value of a group of insurance contracts issued as at the transition date was measured using one of two approaches, the current pricing margin approach or the "adjusted fulfilment cash flows" approach. For both approaches, our requirements were considered a reasonable proxy for a market participant's requirements, as we share the characteristics of a typical market participant in the insurance market. The determination of fair value requires us to make estimates and assumptions that require significant judgment.

The "adjusted fulfilment cash flows" approach identifies specific amounts a market participant would require, in addition to the FCF, to take over the obligations of the group. These include:
•A provision for reinvestment risk, which was measured as the cost of capital for interest rate risk using the higher of the Life Insurance Capital Adequacy Test ("LICAT") and local capital requirements;
•An amount for overhead and other non-directly attributable expenses not covered by FCF; and
•Other adjustments, including a provision for general operational risk and an amount to compensate for the expectation, as at the transition date, that CSM would not be tax-deductible.

The current pricing margin approach identifies the amount a market participant would require by identifying the amount that we require in the current pricing of insurance contracts.

The "adjusted fulfilment cash flows" approach was used for most non-participating insurance and annuity contracts. The current pricing margin approach was used for most fee-based and pass-through contracts.

The fair value of a group of reinsurance contracts held as at the transition date was measured as the difference between the fair value of the group of underlying insurance contracts without consideration of reinsurance, and the fair value of the group of underlying insurance contracts together with the corresponding group of reinsurance contracts held.
CSM at Transition
The CSM at transition for each group of insurance contracts is the fair value of the contracts less the FCF. The FCF at transition were measured using the IFRS 17 policies described in Note 1 and Note 10. The discount curve was established as at the transition date, and became the locked-in discount curve for the group going forward, as the fair value method was applied.

Details on the impacts on the Consolidated Financial Statements due to the adoption of IFRS 17 are included in Note 2.A.iv.
2.A.ii IFRS 9
Summary
During the first quarter, we adopted IFRS 9, which includes guidance on the classification and measurement of financial instruments, impairment of financial assets and hedge accounting, and does not require restatement of comparative periods. IFRS 9 replaces IAS 39 Financial Instruments: Recognition and Measurement ("IAS 39"). As a result of the application of IFRS 9, we changed our accounting policies in the areas indicated below, which were effective beginning January 1, 2023. We are permitted, under IFRS 17, to present comparative information on financial assets as if IFRS 9 were applicable during the comparative period ("classification overlay"). We have elected to apply the classification overlay to our financial assets and their comparative period results as if IFRS 9 had been effective since January 1, 2022. Certain comparative period information will continue to be presented in accordance with our previous accounting policies, as indicated below.
Classification of financial assets and financial liabilities
IFRS 9 introduces three principal classification categories for financial assets. Financial assets are measured at initial recognition at fair value, and are classified as and subsequently measured at FVTPL, FVOCI or amortized cost based on our business model for managing the financial asset and the contractual cash flow characteristics of the asset.

IFRS 9 eliminates the previous IAS 39 categories of held-to-maturity, available-for-sale ("AFS"), and loans and receivable financial assets. Under IFRS 9, derivatives embedded in contracts where the host is a financial asset in scope of IFRS 9 are not separated. Instead, the hybrid financial instrument, as a whole, is assessed for classification.

IFRS 9 maintains the IAS 39 classification for financial liabilities. Under IFRS 9, financial liabilities are measured at either amortized cost or FVTPL.

Further details on how we classify and measure our financial assets and financial liabilities and account for the related gains and losses under IFRS 9 are described in Note 1.
Impairment of financial assets
IFRS 9 replaces the "incurred loss" model under IAS 39 with a forward-looking ECL model. The new impairment model applies to financial assets measured at amortized cost, debt securities measured at FVOCI, mortgages and loans measured at FVOCI, lease receivables, account receivables, loan commitments and financial guarantees not measured at FVTPL. Credit losses are recognized earlier under IFRS 9 as compared previously under IAS 39. Refer to the impairment section in Note 1.
Hedge accounting
IFRS 9 introduced a new hedge accounting model, but permits entities to continue applying hedge accounting requirements under IAS 39 instead of those under IFRS 9. We have elected to continue applying the hedge accounting requirements under IAS 39.
32 Sun Life Financial Inc. December 31, 2023 Notes to the Consolidated Financial Statements Interest Rate Benchmark Reform — Phase 2 amendments


In August 2020, the IASB issued the Interest Rate Benchmark Reform Phase 2, which includes amendments to IFRS 9, IAS 39, IFRS 7 Financial Instruments: Disclosures ("IFRS 7"), IFRS 4, and IFRS 16 Leases ("IFRS 16"). These amendments address issues that arise from the implementation of the reforms, including the replacement of a benchmark with an alternative reference rate (“ARR”), such as the Secured Overnight Financing Rate ("SOFR"), in the case of US dollar London Inter-Bank Offered Rate ("LIBOR"), and the Canadian Overnight Repo Rate Average ("CORRA"), in the case of the Canadian Dollar Offered Rate ("CDOR"). The adoption of these amendments did not have a material impact on our Consolidated Financial Statements.

All LIBOR settings were either discontinued or declared non-representative on or before June 30, 2023. On May 16, 2022, Refinitiv Benchmark Services (UK) Limited, the administrator of CDOR, announced that it will permanently cease the publication of all three tenors of CDOR after June 28, 2024. Concurrently, OSFI published their expectation that Federally Regulated Financial Institutions ("FRFIs") transition all new derivatives and securities to an ARR by June 30, 2023, with no new CDOR exposure being recognized after that date (with limited exceptions for risk management requirements), and that loan agreements referencing CDOR be transitioned by June 28, 2024. FRFIs are also expected to prioritize system and model updates to accommodate the use of CORRA (or any alternative reference rates, as necessary) prior to such date.

Also, with the cessation of CDOR’s publication, the Bankers’ Acceptance ("BA") lending model will be discontinued, and BA issuance is expected to cease. To facilitate the Canadian loan markets’ move away from CDOR and BAs, on July 27, 2023, the Canadian Alternative Reference Rate working group ("CARR"), established by the Canadian Fixed-Income Forum committee of the Bank of Canada ("CFIF"), has implemented a milestone in its two-stage transition plan whereby no new CDOR or BA-related contract should be entered into after November 1, 2023. CFIF has formed a BA-related working group to facilitate a smooth transition away from BAs and to assess potential options to replace them.

In preparation for the above-mentioned benchmark reform, we implemented an Interbank Offered Rate ("IBOR") Transition Program (the "Program") to manage the transition from LIBOR and CDOR to appropriate ARRs. The Program is cross-functional in nature and comprises key stakeholders across our organization and operates with executive oversight. The Program is on track in executing its transition plan, and is mindful of incorporating market developments as they arise. We also actively participate in industry associations and incorporate best practice guidance from these industry associations, as well as regulatory bodies, into the transition plan, such as reviewing and remediating our IBOR-based contracts to incorporate appropriate fallback language. The Program is designed to address the risk and uncertainty relating to our transition to ARRs and other factors relating to reform that could otherwise adversely affect our operations and cash flows and the value of and return on our investments that are IBOR-based. Our affiliated entities with IBOR exposure related to derivatives adhered to the ISDA 2020 IBOR Fallbacks Protocol prior to June 30, 2023, facilitating the transition of our legacy derivative contracts to appropriate ARRs. Our GBP LIBOR exposure transitioned to Sterling Overnight Index Average ("SONIA"), and our remaining US dollar LIBOR and CDOR exposure has transitioned or is expected to transition to appropriate ARRs in the first half of 2024.

As at December 31, 2023, our exposure to US dollar LIBOR consists of non-derivative financial assets of $86 (December 31, 2022 — $2,750), non-derivative financial liabilities of $nil (December 31, 2022 — $77) and derivative notional of $nil (December 31, 2022 — $1,683) that have not yet been confirmed to have transitioned to SOFR. Our exposure to CDOR consists of non-derivative financial assets of $589
(December 31, 2022 — $396), non-derivative financial liabilities of $4,896 (December 31, 2022 — $5,892), and derivative notional of $9,159 (December 31, 2022 — $11,725) that have not yet transitioned to CORRA, excluding financial instruments maturing by June 28, 2024, and including derivatives that are expected to automatically transition to CDOR upon its cessation.
2.A.iii Other Amended International Financial Reporting Standards Adopted in 2023
We adopted the following amendments to IFRS on January 1, 2023. The adoption of these amendments did not have a material impact on our Consolidated Financial Statements:

In May 2021, the IASB issued amendments to IAS 12 Income Taxes ("IAS 12"). The amendments, Deferred Tax related to Assets and Liabilities arising from a Single Transaction, narrow the scope of the recognition exemption in IAS 12 so that it no longer applies to transactions that, on initial recognition, give rise to equal taxable and deductible temporary differences.

In February 2021, the IASB issued amendments to IAS 1 Presentation of Financial Statements ("IAS 1") and IFRS Practice Statement 2 Making Materiality Judgments ("IFRS Practice Statement 2"). The amendments to IAS 1 require companies to disclose their material accounting policy information rather than their significant accounting policies. The amendments to IFRS Practice Statement 2 provide guidance on how to apply the concept of materiality to accounting policy disclosures.

In February 2021, the IASB issued amendments to IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors. The amendments clarify how companies should distinguish changes in accounting policies from changes in accounting estimates.

In May 2023, the IASB issued amendments to IAS 12 to give temporary relief from accounting for deferred taxes arising from Pillar Two model rules, which the Organization for Economic Co-operation and Development ("OECD") published in December 2021. The amendments introduce a mandatory temporary exception to the accounting for deferred taxes arising from jurisdictions implementing the global tax rules and disclosure requirements for affected entities to help users better understand an entity’s exposure to Pillar Two income taxes arising from that legislation, particularly before its effective date. Effective upon issuance, we have applied the mandatory temporary exception which is effective immediately.

On August 4, 2023, the Canadian Department of Finance released draft legislation to implement certain previously announced measures, including application rules for a 15% global minimum tax under OECD’s two-pillar plan, which will apply to Sun Life effective January 1, 2024, however the timing of the substantive enactment of these rules in most jurisdictions where Sun Life operates is uncertain. The Pillar Two rules are not expected to have a material impact on Sun Life’s consolidated financial statements when they become effective.

Total liabilities and equity $ 345,370  $ 4,007  $ (1,326) $ 1,093  $ 349,144 

(1)     Primarily due to measurement impacts from IFRS 9 classification changes on Mortgages and loans of $4,025.
(2)    Due to tax impacts from IFRS 17 and IFRS 9 adoption.
(3)    Certain balances, such as Policy loans and amounts related to premiums, that were previously presented separately or included in Other assets and Other liabilities, are included in the assets or liabilities for Insurance contracts issued or Reinsurance contracts held balances under IFRS 17.
(4)    Increase primarily due to IFRS 17 remeasurement impacts and a requirement to present Insurance contract assets and Reinsurance contract held liabilities separately from Insurance contract liabilities and Reinsurance contract held assets.
(5)    Increase in Insurance contract liabilities and Reinsurance contract held liabilities balances is primarily due to IFRS 17 remeasurement impacts, partially offset by IFRS 17 reclassification impacts. Remeasurement impacts are primarily due to the establishment of CSM of $9.8 billion, the impact of discount rate changes under IFRS 17, and the release of certain reserves held under IFRS 4. Reclassification impacts are primarily offset in Policy loans and Investment contract liabilities.
(6)    Certain contracts previously included in Insurance contract liabilities under IFRS 4 are reclassified to Investment contract liabilities under IFRS 17.
(7)    Consists of a $4.4 billion reduction to Shareholders' equity and a $1.5 billion reduction to Equity in the participating account.
34 Sun Life Financial Inc. December 31, 2023 Notes to the Consolidated Financial Statements As permitted by IFRS 17 and IFRS 9, we have elected to apply the classification and measurement requirements of IFRS 9 to remeasure all financial assets held in comparative periods, including those that were derecognized during that period.


Impact of applying the classification overlay on January 1, 2022
The classification and measurement of these financial assets were based on our expected business model as at January 1, 2022. For financial assets in which the impairment requirements of IFRS 9 applies, we have elected to continue presenting the loss allowance that was determined in accordance with IAS 39.

The impact of applying the classification overlay on the classification and measurement of financial assets for the comparative years are presented below:
Classification Category IAS 39 IFRS 9
Financial instrument IAS 39 IFRS 9 As at
December 31, 2021
Impact of classification overlay As at
January 1, 2022
Assets impacted by the classification overlay:
Debt securities AFS FVTPL $ 125  $ —  $ 125

Assets not impacted by the classification overlay:
Derivative assets FVTPL FVTPL 1,583  —  1,583 
Other financial invested assets FVTPL FVTPL 4,435  —  4,435 
Cash, cash equivalents and short-term securities FVTPL FVTPL 12,278  —  12,278 
Debt securities FVTPL FVTPL 72,449  —  72,449 
Equity securities FVTPL FVTPL 7,538  —  7,538 
Total $ 170,474  $ 4,025  $ 174,499 

(1)    Certain debt securities classified as AFS under IAS 39 are reclassified to FVTPL under IFRS 9, primarily because doing so can eliminate or significantly reduce an accounting mismatch.
(2)    Certain debt securities previously designated at FVTPL under IAS 39 are reclassified to FVOCI under IFRS 9 as they are managed within a business model of collecting contractual cash flows and selling the financial assets, and pass the SPPI test.
(3) Certain equity securities and other financial invested assets were classified as AFS under IAS 39 are reclassified to FVTPL under IFRS 9 and we have not elected to designate them at FVOCI.
(4)    Certain mortgages and loans classified as loans and receivables under IAS 39 are reclassified to FVTPL under IFRS 9, primarily because doing so can eliminate or significantly reduce an accounting mismatch. The carrying value of these mortgages and loans was adjusted to reflect their fair value with the difference recorded in retained earnings.
(5)    Certain mortgages and loans classified as loans and receivables under IAS 39 are reclassified to FVOCI under IFRS 9 as they are held within a business model of collecting contractual cash flows and selling the financial assets, and pass the SPPI test.
(6)    Certain mortgages and loans classified as loans and receivables under IAS 39 are reclassified to amortized cost under IFRS 9 as they are held within a business model of collecting contractual cash flows, and pass the SPPI test.
(7)    Under IAS 39, assets related to CLOs within other financial invested assets were classified as loans and receivables. These assets are managed within a business model of collecting contractual cash flows and selling the financial assets, and pass the SPPI test. Accordingly, we have reclassified these other financial invested assets from amortized cost to FVOCI under IFRS 9.

The classification overlay was applied as at January 1, 2022, with a post-tax impact of $2,873 to opening retained earnings and $(116) to AOCI. Equity in the participating account increased by a post-tax amount of $397. Our accounting policies for the classification of financial instruments under IFRS 9 are set out in Note 1. The application of those accounting policies resulted in the reclassifications presented in the table above.

Classification of financial assets and financial liabilities
The following table summarizes the classification and measurement impact of IFRS 9 as at January 1, 2023, including any reclassification and remeasurement changes from how assets were measured using the classification overlay. Reclassifications represent movements of the carrying amount of financial assets and financial liabilities whose classifications have changed as a result of IFRS 9. Remeasurement represents changes in the carrying amount of the financial assets and financial liabilities due to changes in their measurement.

Equity securities FVTPL 6,824  —  —  6,824 
Total financial assets $ 157,035  $ —  $ 19  $ 157,054 

(1)    Amounts for the year ended December 31, 2022 were adjusted to reflect application of the classification overlay, the recognition of unfunded commitments on FVTPL fixed income assets and the impact of enhancements to our fair value methodology for private fixed income assets. The enhancements increased observability of inputs to the fair valuation of private fixed income assets and resulted in a decrease of $634 in the carrying value of our private fixed income assets as at December 31, 2022. The recognition of unfunded commitments resulted in a decrease of $98 in the carrying value of our mortgages and loans as at December 31, 2022.
(2)    Certain financial assets were reclassified between classification categories upon the adoption of IFRS 17 and IFRS 9 on January 1, 2023. The reclassifications were primarily driven by asset rebalancing between segments where level of sensitivity to interest rates resulted in the designation of certain fixed income assets at FVTPL or a reclassification from FVTPL to FVOCI.
(3)    We adopted impairment requirements under IFRS 9 on January 1, 2023. Remeasurement primarily reflects the difference between IAS 39 incurred loss allowance and IFRS 9 allowance for ECL that affect carrying value. Refer to the Impairment of financial assets table below for remaining adjustments that did not affect carrying value.
(4) The IAS 39 classification category for financial asset balances as at December 31, 2022 can be referenced in the table above describing the impact of the classification overlay.
(5)    The classification of Other financial invested assets related to CLOs as well as the corresponding liabilities were revised from FVOCI and Amortized cost, respectively, to FVTPL to reflect the business model used to manage the assets and liabilities related to CLOs. The impact of this change is not material.

Our financial liabilities were not significantly impacted by the adoption of IFRS 9 on January 1, 2023. Segregated fund contracts and supporting assets were also not significantly impacted by the adoption of IFRS 9 on January 1, 2023, as they maintained a FVTPL classification. The post-tax amounts recognized in opening retained earnings and AOCI on January 1, 2023, as a result of the adoption of
IFRS 9, were $(553) and $553, respectively.
Items previously designated at FVTPL
The following financial assets are classified under IFRS 9 as FVTPL by nature because the assets are managed on a fair value basis, or FVOCI because they are managed under a business model of HTC&S.
IAS 39 IFRS 9

2.B New and Amended International Financial Reporting Standards to be Adopted in 2024
The following new and amended IFRS were issued by the IASB. We expect to adopt these in 2024:

In September 2022, the IASB issued amendments to IFRS 16 to add subsequent measurement requirements for sale and leaseback transactions that satisfy the requirements in IFRS 15 Revenue from Contracts with Customers to be accounted for as a sale. The amendments require a seller-lessee to subsequently measure lease liabilities arising from a leaseback in a way that it does not recognize any amount of the gain or loss that relates to the right of use it retains. The amendments to IFRS 16 will be effective for annual reporting period beginning on or after January 1, 2024, with early application permitted. We do not expect the adoption of these amendments to have a material impact on our Consolidated Financial Statements.

Other
On January 20, 2023, we announced our entry into a 15-year exclusive bancassurance partnership with Dah Sing Bank, Limited. This is our first exclusive bancassurance partnership in Hong Kong and will be a valuable complement to our existing network of insurance advisors. Effective July 1, 2023, we commenced the partnership. We will pay an amount of approximately $260 for this exclusive arrangement, with ongoing variable payments to Dah Sing Bank, Limited based on the success of the partnership.

Effective February 1, 2023, we completed the sale of our sponsored markets business to Canadian Premier Life Insurance Company (re-branded to Securian Canada). Our sponsored markets business includes a variety of association & affinity, and group creditor clients. We disposed of assets of approximately $638 and liabilities of approximately $638. Total consideration received consisted of cash consideration of $98 and contingent consideration of $25. During the first quarter of 2023, we recorded a pre-tax gain on the sale of the business of $102 in Other income on the Consolidated Statements of Operations. The gain on the sale of the business net of goodwill disposed, transaction costs and taxes is $65.

On April 5, 2022, we announced a deepening of our existing bancassurance partnership with PT Bank CIMB Niaga Tbk ("CIMB Niaga") in Indonesia. Under the new agreement, which will be effective in January 2025, we will be the provider of insurance solutions to CIMB Niaga customers across all distribution channels for a term of 15 years, further accelerating our long-term strategy of growing our distribution capacity in the region. The agreement also extends our existing relationship with CIMB Niaga by a term of six years up to 2039. An initial payment of $508 was made on June 30, 2022. $18 of the initial payment related to the existing bancassurance partnership was capitalized as an intangible asset. The remaining $490 will initially be recognized as a prepayment and capitalized as an intangible asset once the agreement becomes effective in 2025. Amortization of this intangible asset will begin in 2025.

4. Segmented Information
We have five reportable business segments: Canada, U.S., Asset Management, Asia, and Corporate. These business segments operate in the financial services industry and reflect our management structure and internal financial reporting. Asset Management includes the results of our MFS and SLC Management business units. Corporate includes the results of our UK business unit and our Corporate Support operations, which include run-off reinsurance operations, as well as investment income, expenses, capital and other items not allocated to our other business groups. Effective the second quarter of 2023, we completed the sale of our UK Business unit. We have retained our economic interest in the annuity business via a reinsurance arrangement that will be reported under the U.S. reportable segment on a prospective basis.

Revenues from our business segments are derived primarily from life and health insurance, investment management and annuities, and mutual funds. Revenues not attributed to the strategic business units are derived primarily from Corporate investments and earnings on capital. Transactions between segments are executed and priced at an arm's-length basis in a manner similar to transactions with third parties.

The expenses in each business segment may include costs or services directly incurred or provided on their behalf at the enterprise level. For other costs not directly attributable to one of our business segments, we use a management reporting framework that uses assumptions, judgments, and methodologies for allocating overhead costs and indirect expenses to our business segments.

Intersegment transactions consist primarily of internal financing agreements which are measured at fair values prevailing when the arrangements are negotiated. Intersegment investment income consists primarily of interest paid by U.S. to Corporate. Intersegment fee income is primarily asset management fees paid by our business segments to Asset Management. SLC Management collects fee income and incurs the operational expenses associated with the management of the general fund assets. Intersegment transactions are eliminated in the Consolidation adjustments column in the following tables.

Management considers its external Clients to be individuals and corporations. We are not reliant on any individual Client as none is individually significant to our operations.

Collateralized Loan Obligations Structure
Crescent, a subsidiary within our Asset Management business segment, issues and manages CLOs. Each CLO is a special purpose vehicle that owns a portfolio of investments, consisting primarily of senior secured loans, and issues various tranches of senior and subordinated notes to third parties for the purpose of financing the purchase of those investments. Assets of the special purpose vehicle, the senior secured loans, are included in Other financial invested assets and the associated liabilities, the senior and subordinated notes issued to third parties, are included in Other liabilities in our Consolidated Statements of Financial Position.

As at December 31, 2023, the carrying value of the assets related to CLOs are $3,478 (December 31, 2022 — $2,880), which consists of cash and accounts receivable of $251 (December 31, 2022 — $292) and loans of $3,227 (December 31, 2022 — $2,588). These underlying loans are mainly below investment grade.

As at December 31, 2023, the carrying value of the liabilities related to CLOs are $3,247 (December 31, 2022 — $2,816). Our maximum contractual exposure to loss related to the CLOs is limited to our investment of $192 (December 31, 2022 — $159) in the most subordinated tranche. The net realized and unrealized loss incurred to date is $43.
5.A.ii Non-Financial Invested Assets
Non-financial invested assets consist of investment properties, investment in associates, subsidiaries and joint ventures which are not consolidated. As at December 31, 2023, the carrying value and fair value of investment properties was $9,723 (December 31, 2022 — $10,102) and $9,723 (December 31, 2022 — $10,102), respectively. The carrying value of other non-financial invested assets which were measured using the equity method of accounting was $1,657 as at December 31, 2023 (December 31, 2022 — $1,652).
Notes to the Consolidated Financial Statements     Sun Life Financial Inc. December 31, 2023 43


5.A.iii Fair Value Methodologies and Assumptions
The specific inputs and valuation techniques used to determine the fair value of our invested assets and financial liabilities are noted below:
Cash, cash equivalents and short-term securities
Cash equivalents are highly liquid investments that are subject to insignificant changes in value and are readily convertible into known amounts of cash. Cash equivalents comprise financial assets with maturities of three months or less from the date of acquisition. Short-term securities comprise financial assets with maturities of greater than three months and less than one year when acquired. Cash, cash equivalents and short-term securities are classified as held for trading for the purpose of meeting short-term cash requirements and accounted for at FVTPL due to their short-term nature or because they are frequently repriced to current market rates.
Government and corporate debt securities
The fair value of government and corporate debt securities is primarily determined using unadjusted quoted prices in active markets for identical or similar securities, where available. When quoted prices in active markets are not available, fair value is determined using market standard valuation methodologies, which include a discounted cash flow method, consensus pricing from various broker dealers that are typically the market makers, or other similar techniques. The assumptions and valuation inputs in applying these market standard valuation methodologies are determined primarily using observable market inputs, which include, but are not limited to, benchmark yields, reported trades of identical or similar instruments, broker-dealer quotes, issuer spreads, bid prices, and reference data including market research publications. In limited circumstances, non-binding broker quotes are used.
Asset-backed securities
The fair value of asset-backed securities is primarily determined using unadjusted quoted prices in active markets for identical or similar securities, where available, or valuation methodologies and valuation inputs similar to those used for government and corporate debt securities. Additional valuation inputs include structural characteristics of the securities, and the underlying collateral performance, such as prepayment speeds and delinquencies. Expected prepayment speeds are based primarily on those previously experienced in the market at projected future interest rate levels. In limited circumstances where there is a lack of sufficient observable market data to value the securities, non-binding broker quotes are used.
Equity securities
The fair value of equity securities is determined using unadjusted quoted prices in active markets for identical securities or similar securities, where available. When quoted prices in active markets are not available, fair value is determined using equity valuation models, which include a discounted cash flow method and other techniques that involve benchmark comparison. Valuation inputs primarily include projected future operating cash flows and earnings, dividends, market discount rates, and earnings multiples of comparable companies. Where equity securities are less frequently traded, the most recent exchange-quoted pricing is used to determine fair value.
Mortgages and loans
The fair value of mortgages and loans is determined by discounting the expected future contractual cash flows using a current market interest rate applicable to financial instruments with a similar yield, credit quality, and maturity characteristics. Valuation inputs typically include benchmark yields and risk-adjusted spreads from current internal lending activities or loan issuances. Beginning in the fourth quarter of 2022, valuation inputs also include external lending activities or loan issuances from both public and private markets, enhancing the market observability of inputs. The risk-adjusted spreads are determined based on the borrower’s credit and liquidity, as well as term and other loan-specific features.
Derivative financial instruments
The fair value of derivative financial instruments depends upon derivative types. The fair value of exchange-traded futures and options is determined using unadjusted quoted prices in active markets, where available, while the fair value of over-the-counter ("OTC") derivatives is determined using pricing models, such as a discounted cash flow method or other market standard valuation techniques, with primarily observable market inputs. Valuation inputs used to price OTC derivatives may include swap interest rate curves, foreign exchange spot and forward rates, index prices, the value of underlying securities, projected dividends, volatility surfaces, and in limited circumstances, counterparty quotes. The fair value of OTC derivative instruments also includes credit valuation adjustments to reflect the credit risk of both the derivative counterparty and ourselves as well as the impact of contractual factors designed to reduce our credit exposure, such as collateral and legal rights of offset under master netting agreements. Inputs into determining the appropriate credit valuation adjustments are typically obtained from publicly available information and include credit default swap spreads when available, credit spreads derived from specific bond yields, or published cumulative default experience data adjusted for current trends when credit default swap spreads are not available.
Other financial invested assets
The fair value of other financial invested assets consists primarily of limited partnership investments which is based on net asset value ("NAV") provided by management of the limited partnership investments. Based on the unobservable nature of these NAVs, we do not assess whether applying reasonably possible alternative assumptions would have an impact on the fair value of the limited partnership investments.
Investment properties
The fair value of investment properties is generally determined using property valuation models that are based on expected capitalization rates and models that discount expected future net cash flows at current market interest rates reflective of the characteristics, location, and market of each property. Expected future net cash flows include contractual and projected cash flows and forecasted operating expenses, and take into account interest, rental, and occupancy rates derived from market surveys. The estimates of future cash inflows in addition to expected rental income from current leases, include projected income from future leases based on significant assumptions that are consistent with current market conditions. The future rental rates are estimated based on the location, type, and quality of the properties, and take into account market data and projections at the valuation date. The fair values are typically compared to market-based information for reasonability, including recent transactions involving comparable assets. The methodologies and inputs used in these models are in accordance with real estate industry valuation standards. Valuations are prepared externally or internally by professionally accredited real estate appraisers.
44 Sun Life Financial Inc. December 31, 2023 Notes to the Consolidated Financial Statements The fair value of investments for account of segregated fund holders is determined using unadjusted quoted prices in active markets or independent valuation information provided by investment managers.


Investments for account of segregated fund holders
The fair value of direct investments within investments for account of segregated fund holders, such as short-term securities and government and corporate debt securities, is determined according to valuation methodologies and inputs described above in the respective asset type sections.
Investment contract liabilities
The fair value of investment contracts is measured through the use of prospective discounted cash flow method. For unit-linked contracts, the fair value is equal to the current unit fund value, plus additional non-unit liability amounts on a fair value basis if required. For non-unit-linked contracts, the fair value is equal to the present value of contractual cash flow. The fair value of the investment contract liabilities approximate their carrying values due to the nature of the contracts.
Obligations for securities borrowing
The fair values of these obligations are based on the fair value of the underlying securities, which can include debt or equity securities. The method used to determine fair value is based on the quoted market prices where available in an active market.
Other financial liabilities
The fair value of other financial liabilities is determined using the discounted contractual cash flow methodology at the incremental borrowing rate or the effective interest rate, where available. Other financial liabilities categorized as Level 3 represent the present value of the estimated price we would pay to acquire any remaining outstanding shares upon exercise of a put option and any mandatory income distributions. The fair value of the liabilities is based on the average earnings before income tax, depreciation and amortization ("EBITDA") for the preceding years before the options’ exercise dates and EBITDA multiples in accordance with the put agreements as well as the expected amount of any mandatory income distributions. A change in EBITDA would impact the fair value of other financial liabilities and our net income (loss).
Collateralized loan obligations
The fair value of underlying assets within our CLOs is determined primarily using observable market inputs, such as quoted prices for similar assets in active markets and other observable market data.

The fair value of underlying liabilities within our CLOs is determined by discounting expected future contractual cash flows using a current market interest rate applicable to financial instruments with a similar yield, credit quality, maturity characteristics, and structural credit protections. The valuation technique maximizes the use of observable inputs that incorporates comparable securities’ prices and other market intelligence.
5.A.iv Fair Value Hierarchy
We categorize our assets and liabilities carried at fair value based on the priority of the inputs to the valuation techniques used to measure fair value, into a three-level fair value hierarchy as follows:

Level 1: Fair value based on the unadjusted quoted prices for identical instruments in active markets represents a Level 1 valuation. Where possible, valuations are based on quoted prices or observable inputs obtained from active markets. The types of assets and liabilities classified as Level 1 generally include cash and cash equivalents, certain U.S. government and agency securities, exchange-traded equity securities, and certain segregated and mutual fund units held for account of segregated fund holders.

Level 2: Fair value is based on quoted prices for similar assets or liabilities traded in active markets, or prices from valuation techniques that use significant observable inputs, or inputs that are derived principally from or corroborated with observable market data through correlation or other means. When a fair value is based on all significant market observable inputs, the valuation is classified as Level 2. Financial instruments traded in a less active market are valued using indicative market prices, the present value of cash flows or other valuation methods. The types of assets and liabilities classified as Level 2 generally include Canadian federal, provincial and municipal government, other foreign government and corporate debt securities, certain asset-backed securities, repurchase agreements, OTC derivatives, and certain segregated and mutual fund units held for account of segregated fund holders.

Level 3: Fair value is based on valuation techniques that require one or more significant inputs that are not based on observable market inputs. These unobservable inputs reflect our expectations about the assumptions market participants would use in pricing the asset or liability. Where financial instruments trade in inactive markets or when using models where observable parameters do not exist, significant management judgment is required for valuation methodologies and model inputs. The types of assets and liabilities classified as Level 3 generally include certain corporate bonds, certain asset-backed securities, certain other financial invested assets, investment properties, and certain segregated and mutual fund units held for account of segregated fund holders.

(1)    Included in Net investment income (loss) in our Consolidated Statements of Operations for Total invested assets measured at fair value.
(2)    Total gains and losses in net income (loss) and OCI are calculated assuming transfers into or out of Level 3 occur at the beginning of the period. For an asset or liability that transfers into Level 3 during the reporting period, the entire change in fair value for the period is included in the table above. For transfers out of Level 3 during the reporting period, the change in fair value for the period is excluded from the table above.
(3)    Investment properties included in net income is comprised of fair value changes on investment properties of $(486) for the year ended December 31, 2023, (December 31, 2022 — $667), net of amortization of leasing commissions and tenant inducements of $34 for the year ended December 31, 2023, (December 31, 2022 — $42). As at December 31, 2023, we have used assumptions that reflect known changes in the property values including changes in expected future cash flows.
(4)    Transfers into Level 3 occur when the inputs used to price the assets and liabilities lack observable market data, and as a result, no longer meet the Level 1 or 2 definitions at the reporting date. Transfers out of Level 3 occur when the pricing inputs become more transparent and satisfy the Level 1 or 2 criteria and are primarily the result of observable market data being available at the reporting date, thus removing the requirement to rely on inputs that lack observability.
(5)    Foreign currency translation relates to the foreign exchange impact of translating Level 3 assets and liabilities of foreign subsidiaries from their functional currencies to Canadian dollars.
(6)    Mortgages and loans were classified as amortized cost under IAS 39 for the year ended December 31, 2021. On application of the classification overlay on January 1, 2022, mortgages and loans are measured at FVTPL or FVOCI. During the fourth quarter of 2022, we had a change to our fair value methodology for mortgages and loans that constitutes a change in estimate as at December 31, 2022. Levelling changed from Level 3 to Level 2 as a result of applying fair value enhancements in valuing mortgages and loans supporting insurance liabilities. See Mortgages and loans section above for further details.
48 Sun Life Financial Inc. December 31, 2023 Notes to the Consolidated Financial Statements Our assets categorized in Level 3 of the fair value hierarchy are primarily Investment properties, Mortgages and loans, Debt securities and Other invested assets (financial and non-financial).


Unobservable Inputs and Sensitivity for Level 3 Assets

The fair value of Investment properties is determined by using the discounted cash flow methodology as described in Note 5.A.iii. The key unobservable inputs used in the valuation of investment properties as at December 31, 2023 include the following:
•Estimated rental value: The estimated rental value is based on contractual rent and other local market lease transactions, net of reimbursable operating expenses. An increase (decrease) in the estimated rental value would result in a higher (lower) fair value. The estimated rental value varies depending on the property types, which include retail, office, and industrial properties. The estimated rental value (in dollars, per square foot, per annum) ranges from $12.00 to $76.00 for retail and office properties and from $3.00 to $23.00 for industrial properties.
•Rental growth rate: The rental growth rate is typically estimated based on expected market behaviour, which is influenced by the type of property and geographic region of the property. An increase (decrease) in the rental growth rate would result in a higher (lower) fair value. The rental growth rate (per annum) ranges from 0.00% to 3.00%, however the one- to two-year short-term rent curve is either below or above this range for select properties.
•Long-term vacancy rate: The long-term vacancy rate is typically estimated based on expected market behaviour, which is influenced by the type of property and geographic region of the property. An increase (decrease) in the long-term vacancy rate would result in a lower (higher) fair value. The long-term vacancy rate ranges from 2.00% to 10.00%.
•Discount rate: The discount rate is derived from market activity across various property types and geographic regions and is a reflection of the expected rate of return to be realized on the investment over the next 10 years. An increase (decrease) in the discount rate would result in a lower (higher) fair value. The discount rate ranges from 5.50% to 10.00%.
•Terminal capitalization rate: The terminal capitalization rate is derived from market activity across various property types and geographic regions and is a reflection of the expected rate of return to be realized on the investment over the remainder of its life after the 10-year period. An increase (decrease) in the terminal capitalization rate would result in a lower (higher) fair value. The terminal capitalization rate ranges from 4.00% to 8.50%.

Changes in the estimated rental value are positively correlated with changes in the rental growth rate. Changes in the estimated rental value are negatively correlated with changes in the long-term vacancy rate, the discount rate, and the terminal capitalization rate.

Our Mortgages and loans, categorized in Level 3, are included in Mortgages and loans – FVTPL and Mortgages and loans – FVOCI in the
Level 3 roll forward table, and Mortgages and loans – Amortized cost in Note 5.A.i. The fair value of these mortgages and loans is determined by using the discounted cash flow methodology. The key unobservable inputs used in the valuation of mortgages and loans as at December 31, 2023 include credit spreads and liquidity adjustments. The credit spread is the difference between the instrument yield and the benchmark yield. The benchmark yield is determined by matching each asset by geography, sector, rating and maturity to a matrix comprised of spreads of publicly available corporate bonds. In some cases, a liquidity premium or discount may be applied if recent private spreads differ from public spreads. The credit spreads range from 0.50% to 4.50%. The liquidity adjustments range from a discount of 1.00% to a premium of 2.00%. Changes in the fair value of mortgages and loans are negatively correlated with changes in credit spread and liquidity adjustments.

Our Debt securities categorized in Level 3, which are included in Debt securities – FVTPL and Debt securities – FVOCI in the Level 3 roll forward table, consist primarily of corporate bonds. The fair value of these corporate bonds is generally determined using broker quotes that cannot be corroborated with observable market transactions. Significant unobservable inputs for these corporate bonds would include issuer spreads, which are comprised of credit, liquidity, and other security-specific features of the bonds. A decrease (increase) in these issuer spreads would result in a lower (higher) fair value. Due to the unobservable nature of these broker quotes, we do not assess whether applying reasonably possible alternative assumptions would have an impact on the fair value of the Level 3 corporate bonds. The majority of our debt securities categorized in Level 3 are FVTPL assets supporting insurance contract liabilities. Changes in the fair value of these assets supporting insurance contract liabilities are largely offset by changes in the corresponding insurance contract liabilities. As a result, though using reasonably possible alternative assumptions may have an impact on the fair value of the Level 3 debt securities, it would not have a significant impact on our Consolidated Financial Statements.

The Other financial invested assets categorized in Level 3, which are included in Other financial invested assets – FVTPL and Other financial invested assets – FVOCI in the Level 3 roll forward table, consists primarily of limited partnership investments. The fair value of our limited partnership investments is based on NAV provided by management of the limited partnership investments. Based on the unobservable nature of these NAVs, we do not assess whether applying reasonably possible alternative assumptions would have an impact on the fair value of the Level 3 limited partnership investments.
Valuation Process for Level 3 Assets
Our assets categorized in Level 3 of the fair value hierarchy are primarily Investment properties, Debt securities (including asset-backed securities), Mortgages and loans and limited partnership investments included in Other financial invested assets. Our valuation processes for these assets are as follows:

The fair value of investment properties are based on the results of appraisals performed annually and reviewed quarterly for material changes. The valuation methodology used to determine the fair value is in accordance with the standards of the Appraisal Institute of Canada, the U.S., and the UK. Investment properties are appraised externally at least once every three years. Investment properties not appraised externally in a given year are reviewed by qualified appraisers. A management committee, including investment professionals, reviews the fair value of investment properties for overall reasonability.

The fair value of mortgages and loans is based on an internal discounted cash flow model, subject to detailed review and validation to ensure overall reasonability.

The fair value of debt securities is generally obtained by external pricing services. We obtain an understanding of inputs and valuation methods used by external pricing services. When fair value cannot be obtained from external pricing services, broker quotes, or internal models subject to detailed review and validation processes are used. The fair value of debt securities is subject to price validation and review procedures to ensure overall reasonability.
Notes to the Consolidated Financial Statements     Sun Life Financial Inc. December 31, 2023 49



The fair value of limited partnership investments, included in Other financial invested assets, is based on NAV. The financial statements used in calculating the NAV are generally audited annually. We review the NAV of the limited partnership investments and perform analytical and other procedures to ensure the fair value is reasonable.

Investment contracts for account of segregated funds can be surrendered and units in the segregated funds can be redeemed by the holder at any time. Accordingly, the fair values of investment contract liability and the liability for investment contracts for account of segregated fund holders are not less than the amount payable on demand. Their fair values are based on the fair value of the underlying items less any accrued fees and surrender charges and approximate their carrying values.

5.E Derivative Financial Instruments and Hedging Activities
We apply hedge accounting to minimize volatility in income and equity caused by changes in interest rates or foreign exchange rates. Interest rate and currency fluctuations will either cause assets and liabilities to appreciate or depreciate in market value or cause variability in forecasted cash flows. When a hedging relationship is effective, gains, losses, revenue and expenses of the hedging instrument will offset the gains, losses, revenue and expenses of the hedged item. Derivatives used in hedging relationships are recorded in Derivative assets or Derivative liabilities on the Consolidated Statements of Financial Position.
5.E.i Derivatives Held for Risk Management
We use other derivatives, not designated in a qualifying hedging relationship ("Derivatives investments"), to manage exposure to foreign currency, interest rate, and equity market. The instruments used include principally interest rate swaps, cross-currency swaps, forward contracts, interest rate futures, interest rate options, credit and swaps and equity swaps.

The following table describes the fair value of derivatives held for risk management purposes by type of risk exposure.

5.E.ii Hedge Accounting
Fair Value Hedges
We use interest rate swaps to hedge exposure to changes in the fair values of fixed rate debt securities and mortgages and loans in respect of the US LIBOR benchmark interest rate. Pay-floating/receive-fixed interest rate swaps are matched to specific issuances of fixed-rate notes or pay-fixed/receive-floating interest rate swaps are matched to fixed-rate loans and advances with terms that closely align with the critical terms of the hedged item.

Our approach to managing market risk, including interest rate risk, is discussed in Note 6. Our exposure to interest rate risk is disclosed in Note 6. Interest rate risk to which we apply hedge accounting arises from fixed-rate debt securities, mortgages and loans, whose fair value fluctuates when benchmark interest rates change. We hedge interest rate risk only to the extent of benchmark interest rates because the changes in fair value of a fixed rate note or loan are significantly influenced by changes in the benchmark interest rate. Hedge accounting is applied where economic hedging relationships meet the hedge accounting criteria. By using derivative financial instruments to hedge exposures to changes in interest rates, we are also exposed to the credit risk of the derivative counterparty, which is not offset by the hedged
Notes to the Consolidated Financial Statements     Sun Life Financial Inc. December 31, 2023 53


item. We minimize counterparty credit risk in derivative instruments by entering into transactions with high-quality counterparties whose credit rating is investment grade.

Before fair value hedge accounting is applied, we determine whether an economic relationship between the hedged item and the hedging instrument exists based on an evaluation of the qualitative characteristics of these items and the hedged risk that is supported by quantitative analysis. We consider whether the critical terms of the hedged item and hedging instrument closely align when assessing the presence of an economic relationship. We evaluate whether the fair value of the hedged item and the hedging instrument respond similarly to similar risks, and further support this qualitative assessment by using regression analysis to assess whether the hedging instrument is expected to be and has been highly effective in offsetting changes in the fair value of the hedged item.

Potential sources of hedge ineffectiveness can be attributed to differences between hedging instruments and hedge items:
•The effect of the counterparty and our own credit risk on the fair value of the interest rate swap, which is not reflected in the fair value of the hedged item attributable to the change in interest rate.
•Differences in maturities of the interest rate swap and the loans or debt securities.
•Mismatches in the frequency and timing of when interest rates are reset and frequency of payment.
•Differences in the discounting factors between the hedged item and hedging instrument.

The effective portion of fair value gains on derivatives held in qualifying fair value hedging relationships and the hedging gain (loss) on the hedged items are included in net gains (losses) on the Consolidated Statements of Comprehensive Income (Loss).

We did not have any fair value hedges held as at December 31, 2023.

Assets and liabilities designated as hedged items as at December 31, 2022 are provided below:

Cash flow hedges
We use pay fixed/receive floating interest rate and cross-currency interest rate swaps to hedge the interest rate risks in respect of the benchmark interest rate (mainly sterling and US dollar LIBOR and Euribor or SONIA, SOFR) and foreign currency risks (mainly U.S. dollar and sterling or SONIA, SOFR) from its issuance of floating-rate notes denominated in foreign currencies. We hedge interest rate risk to the extent of benchmark interest rate exposure on its floating-rate notes to mitigate variability in its cash flows. Hedge accounting is applied where economic hedging relationships meet the hedge accounting criteria.

We also hedge the variability of cash payments associated with changes in SLFC prices using total return forwards ("TRF"). This is related to our Sun Share Unit ("Sun Share") Plan as a long-term incentive award to executive employees.

Our exposure to market risk and our approach to managing market risk, including interest rate risk and foreign currency risk, are discussed in Note 6.

We determine the amount of the exposure to which it applies hedge accounting by assessing the potential impact of changes in interest rates and foreign currency exchange rates on the future cash flows from its issuance of floating-rate notes denominated in foreign currencies. This assessment is performed using analytical techniques, such as cash flow sensitivity analysis.

We manage our exposure to credit risk of the counterparties to the derivatives, which is not offset by the hedged items, in a similar manner as described above for the fair value hedges.

We determine whether an economic relationship exists between the cash flows of the hedged item and hedging instrument based on an evaluation of the qualitative characteristics of these items and the hedged risk that is supported by quantitative analysis. We consider whether the critical terms of the hedged item and hedging instrument closely align when assessing the presence of an economic relationship. We evaluate whether the cash flows of the hedged item and the hedging instrument respond similarly to the hedged risk, such as the benchmark interest rate or foreign currency. For cash flow hedging relationships directly impacted by IBOR reform (i.e. hedges of U.S. dollar LIBOR and sterling LIBOR), we assume that the cash flows of the hedged item and hedging instrument will not be altered as a result of IBOR reform. We further support this qualitative assessment by using regression analysis to assess whether the hedging instrument is expected to be and has been highly effective in offsetting changes in the present value of the hedged item. We assess hedge effectiveness using the
54 Sun Life Financial Inc. December 31, 2023 Notes to the Consolidated Financial Statements hypothetical derivative method, which creates a derivative instrument to serve as a proxy for the hedged transaction.


The terms of the hypothetical derivative match the critical terms of the hedged item and it has a fair value of zero at inception. We assess whether the derivative designated in each hedging relationship is expected to be and has been highly effective in offsetting changes in cash flows of the hedged item (prospectively and retrospectively) using this regression analysis.

Potential sources of hedge ineffectiveness can be attributed to differences between hedging instruments and hedge items:
•The effect of the counterparty and our own credit risk on the fair value of the interest rate swap, which is not reflected in the fair value of the hedged item attributable to the change in interest rate.
•Differences in maturities of the interest rate swap and the loans or debt securities.
•Mismatches in the frequency and timing of when interest rates are reset and frequency of payment.
•Differences in the discounting factors between the hedged item and hedging instrument.

There were no other sources of ineffectiveness in these hedging relationships.

The maturity analysis of the notional amounts and the average rates (or weighted average rates, if applicable) and prices of the hedging instruments are disclosed in Note 6.A.iv.

(3)    Hedged items includes other liabilities, representing share-based payment awards.
Net investment hedges
A foreign currency exposure could arise from a net investment in subsidiaries that have a different functional currency. The risk arises from the fluctuation in spot exchange rates between the functional currency of the subsidiaries and our functional currency, which causes the amount of the net investment to vary in the Consolidated Financial Statements. Our policy is to hedge these exposures only when not doing so would be expected to have a significant impact on the regulatory capital ratios and our subsidiaries’ operations. We use a mixture of forward foreign exchange contracts and foreign currency denominated debt as hedging instruments. When the hedging instrument is foreign currency denominated debt, we assess effectiveness by comparing past changes in the carrying amount of the debt that are attributable to a change in the spot rate with past changes in the investment in the foreign operation due to movement in the spot rate. We hedge the net investment only to the extent of the debt principal; therefore, the hedge ratio is established by aligning the principal amount of the debt with the carrying amount of the net investment that is designated.

When the hedging instrument is a forward foreign exchange contract, we establish a hedge ratio where the notional on the forward foreign exchange contract matches the carrying amount of the designated net investment, and ensure that the foreign currency in which the hedging instrument is denominated is the same as the functional currency of the net investment.
Notes to the Consolidated Financial Statements     Sun Life Financial Inc. December 31, 2023 55



Because we expect to hold the net investment for a period longer than the maturity of the forward foreign exchange contract, and our policy is to hedge the net investment only to the extent of the nominal amount of the foreign exchange leg of the derivative, the only source of ineffectiveness that is expected to arise from these hedging relationships is due to the effect of the counterparty and own credit risk on the fair value of the derivative, which is not reflected in the fair value of the hypothetical derivative.

We did not have any net investment hedges held as at December 31, 2023 or December 31, 2022.

5.F Transfers of Financial Assets
We enter into transactions, including mortgage securitization, repurchase agreements and securities lending, where we transfer financial assets while retaining the risks and rewards of ownership of the assets. These transferred financial assets are not derecognized and remain on our Consolidated Statements of Financial Position. The carrying value of the transferred assets and the associated liabilities are described in the sections below.
5.F.i Mortgage Securitization
We securitize certain insured fixed-rate commercial mortgages through the creation of mortgage-backed securities under the National Housing Act Mortgage-Backed Securities ("NHA MBS") Program sponsored by the Canada Mortgage and Housing Corporation ("CMHC"). The NHA MBS are then sold to Canada Housing Trust, a government-sponsored security trust that issues securities to third-party investors under the Canadian Mortgage Bond ("CMB") program. The securitization of these assets does not qualify for derecognition as we have not transferred substantially all of the risks and rewards of ownership. Specifically, we continue to be exposed to pre-payment and interest rate risk associated with these assets. There is no ECL on the securitized mortgages, as the mortgages were already insured by the CMHC prior to securitization. These assets continue to be recognized as Mortgages and loans in our Consolidated Statements of Financial Position. Proceeds from securitization transactions are recognized as secured borrowings and included in Other liabilities in our Consolidated Statements of Financial Position.

Receipts of principal on the securitized mortgages are deposited into a principal reinvestment account ("PRA") to meet our repayment obligation upon maturity under the CMB program. The assets in the PRA are typically comprised of cash and cash equivalents and certain asset-backed securities. We are exposed to reinvestment risk due to the amortizing nature of the securitized mortgages relative to our repayment obligation for the full principal amount due at maturity. We mitigate this reinvestment risk using interest rate swaps.

The carrying value and fair value of the securitized mortgages as at December 31, 2023 are $1,792 and $1,697, respectively (December 31, 2022 — $1,926 and $1,793, respectively). The carrying value and fair value of the associated liabilities as at December 31, 2023 are $2,119 and $2,021, respectively (December 31, 2022 — $2,158 and $2,018, respectively). The carrying value of securities in the principal reinvestment account (''PRA'') as at December 31, 2023 is $335 (December 31, 2022 — $244). There are $57 cash and cash equivalents in the PRA as at December 31, 2023 (December 31, 2022 — $nil).
The fair value of the secured borrowings from mortgage securitization is based on the methodologies and assumptions for asset-backed securities described in Note 5.A.iii. The fair value of these liabilities is categorized in Level 2 of the fair value hierarchy as at December 31, 2023 and 2022.
5.F.ii Repurchase Agreements
We enter into repurchase agreements for operational funding and liquidity purposes. Repurchase agreements have maturities ranging from 8 to 365 days, averaging 100 days, and bear interest at an average rate of 4.86% as at December 31, 2023 (December 31, 2022 — 3.90%). The carrying values of the transferred assets and the obligations related to their repurchase, which approximate their fair values, are $2,705 as at
56 Sun Life Financial Inc. December 31, 2023 Notes to the Consolidated Financial Statements December 31, 2023 (December 31, 2022 — $2,725).


These liabilities are categorized in Level 2 of the fair value hierarchy. Collateral primarily consists of cash and cash equivalents as well as government guaranteed securities. Details on the collateral pledged are included in Note 6.A.ii.
5.F.iii Securities Lending
The Company engages in securities lending to generate additional income. Certain securities from its portfolio are lent to other institutions for short periods. Collateral exceeding the fair value of the securities lent is deposited by the borrower with a lending agent, usually a securities custodian, and maintained by the lending agent until the underlying security has been returned to us. The fair value of the securities lent is monitored on a daily basis with additional collateral obtained or refunded as the fair values fluctuate. Collateral primarily consists of Canadian federal and provincial government securities and cash and cash equivalents. Certain arrangements allow us to invest the cash collateral received for the securities lent. The carrying values of the securities lent approximate their fair values. The carrying values of the securities lent and the related collateral held are $2,044 and $2,158 respectively, as at December 31, 2023 (December 31, 2022 — $2,202 and $2,322, respectively). Of the collateral held, we held cash collateral of $187 as at December 31, 2023 (December 31, 2022 — $215), which is recognized on our Consolidated Statements of Financial Position.

6. Financial Instrument Risk Management

The significant risks related to financial instruments are credit risk, market risk (including equity risk, real estate risk, interest rate and spread risk, foreign currency risk, and inflation risk) and liquidity risk.

We use derivative instruments to manage market risks related to equity market, interest rate and currency fluctuations and in replication strategies for permissible investments. We do not engage in speculative investment in derivatives. The gap in market sensitivities or exposures between liabilities and supporting assets is monitored and managed within defined tolerance limits, by using derivative instruments, where appropriate. We use models and techniques to measure the effectiveness of our risk management strategies.
6.A Credit Risk
Risk Description
Credit risk is the possibility of loss from amounts owed by our borrowers or financial counterparties. We are subject to credit risk in connection with issuers of securities held in our investment portfolio, debtors, structured securities, reinsurers, counterparties (including derivative, repurchase agreement and securities lending counterparties), other financial institutions and other entities. Losses may occur when a counterparty fails to make timely payments pursuant to the terms of the underlying contractual arrangement or when the counterparty's credit rating or risk profile otherwise deteriorates. Credit risk can also arise in connection with deterioration in the value of, or ability to realize, any underlying security that may be used as collateral for the debt obligation. Credit risk can occur as a result of broad economic conditions, challenges within specific sectors of the economy, or from issues affecting individual companies. Events that result in defaults, impairments or downgrades of the securities in our investment portfolio would cause the Company to record realized or unrealized losses and may cause an increase in our provisions for asset default, adversely impacting earnings.
Credit Risk Management Governance and Control
We rate fixed income investments primarily through the use of internally developed scorecards which combine an estimated probability of default and loss given default to determine an expected loss and credit risk rating. This rating is expressed using a 22-point scale that is generally consistent with those used by external rating agencies, and is based on detailed examination of the borrower's, or issuer's, credit quality and the characteristics of the specific instrument. The probability of default assessment is based on borrower-level or issuer-level analysis, which encompasses an assessment of industry risk, business strategy, competitiveness, strength of management and other financial information. The loss given default assessment is based on instrument-level analysis, which considers the impact of guarantees, covenants, liquidity and other structural features. These scorecards provide input to stochastic value-at-risk models and are used to stress test the portfolio, which provide insight into the distribution and characteristics of credit risk within our portfolios. In accordance with our policies and under normal circumstances, our ratings cannot be higher than the highest rating provided by certain Nationally Recognized Statistical Rating Organizations ("NRSROs"). Certain assets, including those in our sovereign debt and asset-backed securities portfolios, are assigned a rating based on ratings provided by NRSROs using a priority sequence order of Standard & Poor's, Moody's, Fitch and DBRS Limited.

We employ a wide range of credit risk management practices and controls, as outlined below:
•Credit risk governance practices are in place, including independent monitoring and review and reporting to senior management and the Risk Committee.
•Risk appetite limits have been established for credit risk.
•Income and regulatory capital sensitivities are monitored, managed and reported against pre-established risk limits.
•Comprehensive Investment and Credit Risk Management Policy, guidelines and practices are in place.
•Specific investment diversification requirements are in place, such as defined investment limits for asset class, geography, and industry.
•Risk-based credit portfolio, counterparty, and sector exposure limits have been established.
•Mandatory use of credit quality ratings for portfolio investments has been established and is reviewed regularly. These internal rating decisions for new fixed income investments and ongoing review of existing rating decisions are independently adjudicated by Corporate Risk Management.
•Comprehensive due diligence processes and ongoing credit analyses are conducted.
•Regulatory solvency requirements include risk-based capital requirements and are monitored regularly.
•Comprehensive compliance monitoring practices and procedures including reporting against pre-established investment limits are in place.
•Reinsurance exposures are monitored to ensure that no single reinsurer represents an undue level of credit risk.
•Stress-testing techniques, such as Financial Condition Testing ("FCT"), are used to measure the effects of large and sustained adverse credit developments.
•Insurance contract liabilities are established in accordance with Canadian actuarial standards of practice.
•Internal capital targets are established at an enterprise level to cover all risks and are above minimum regulatory and supervisory levels. Actual capital levels are monitored to ensure they exceed internal targets.
Notes to the Consolidated Financial Statements     Sun Life Financial Inc. December 31, 2023 57


6.A.i Maximum Exposure to Credit Risk
Our maximum credit exposure related to financial instruments as at December 31 is the balance as presented in our Consolidated Statements of Financial Position as we believe that these carrying amounts best represent the maximum exposure to credit risk. The credit exposure for debt securities may be increased to the extent that the amounts recovered from default are insufficient to satisfy the actuarial liability cash flows that the assets are intended to support.

The positive fair value of derivative assets is used to determine the credit risk exposure if the counterparties were to default. The credit risk exposure is the cost of replacing, at current market rates, all derivative contracts with a positive fair value. Additionally, we have credit exposure to items not on the Consolidated Statements of Financial Position as follows:
As at December 31, 2023 2022
Off-balance sheet item:
Loan commitments(1)
$ 2,061  $ 2,217 

(1)    Loan commitments include commitments to extend credit under commercial and multi-family residential mortgages and private debt securities not quoted in an active market. Commitments on debt securities contain provisions that allow for withdrawal of the commitment if there is deterioration in the credit quality of the borrower.
6.A.ii Right of Offset and Collateral
We invest in financial assets which may be secured by real estate properties, pools of financial assets, third-party financial guarantees, credit insurance, and other arrangements.

For OTC derivatives, collateral is collected from and pledged to counterparties to manage credit exposure according to the Credit Support Annex ("CSA"), which forms part of the International Swaps and Derivatives Association's ("ISDA") master agreements. It is common practice to execute a CSA in conjunction with an ISDA master agreement. Under the ISDA master agreements for OTC derivatives, we have a right of offset in the event of default, insolvency, bankruptcy, or other early termination. In the ordinary course of business, bilateral OTC exposures under these agreements are substantially mitigated through associated collateral agreements with a majority of our counterparties.

For exchange-traded derivatives subject to derivative clearing agreements with the exchanges and clearinghouses, there is no provision for set-off at default. Initial margin is excluded from the table below as it would become part of a pooled settlement process.

For repurchase agreements and reverse repurchase agreements, assets are sold or purchased with a commitment to resell or repurchase at a future date. Additional collateral may be pledged to or collected from counterparties to manage credit exposure according to bilateral repurchase or reverse repurchase agreements. In the event of default by a counterparty, we are entitled to liquidate the assets we hold as collateral to offset against obligations to the same counterparty.

In the case of securities lending or borrowing, assets are lent or borrowed with a commitment from or to the counterparty to return at a future date. For securities lending, cash or securities are received as collateral from the counterparty; for securities borrowing, debt securities are pledged as collateral to the counterparty. In the event of default by the counterparty, we are entitled to liquidate the assets we hold as collateral to offset against obligations to the same counterparty.

58 Sun Life Financial Inc. December 31, 2023 Notes to the Consolidated Financial Statements We do not offset financial instruments in our Consolidated Statements of Financial Position, as our rights of offset are conditional.


The following tables present the effect of conditional netting and similar arrangements. Similar arrangements include global master repurchase agreements, security lending agreements, and any related rights to financial collateral.

6.A.iii Concentration Risk
Concentrations of credit risk arise from exposures to a single debtor, a group of related debtors, or groups of debtors that have similar credit risk characteristics, such as groups of debtors in the same economic or geographic regions or in similar industries. Related issuers may have similar economic characteristics so that their ability to meet contractual obligations may be impacted similarly by changes in the economic or political conditions. We manage this risk by appropriately diversifying our investment portfolio through the use of concentration limits. In particular, we maintain policies which set counterparty exposure limits to manage the credit exposure for investments in any single issuer or to the same underlying credit. Exceptions exist for investments in securities which are issued or guaranteed by the Government of Canada, U.S. or UK and issuers for which the Risk Committee have granted specific approval. Mortgages are collateralized by the related property, and generally do not exceed 75% of the value of the property at the time the original loan is made. Our mortgages and loans are diversified by type and location and, for mortgages, by borrower. Loans provide diversification benefits (name, industry and geography) and often provide stronger covenants and collateral than public debt securities, thereby providing both better credit protection and potentially higher recoveries in the event of default. The following tables provide details of the debt securities, mortgages and loans held by issuer country, geographic location and industry sector, where applicable.

The carrying value of debt securities by geographic location is shown in the following table. The geographic location is based on the country of the creditor's parent.

6.A.v Asset Quality
The following sections describe our assessment of the credit quality of our financial assets. We monitor credit quality based on internal ratings as well as ratings assigned by external rating agencies where available.
Derivative Financial Instruments by Counterparty Credit Rating
Derivative instruments consist of bilateral OTC contracts negotiated directly between counterparties, OTC contracts cleared through central clearing houses or exchange-traded contracts. Since a counterparty failure in an OTC derivative transaction could render it ineffective for hedging purposes, we generally transact our derivative contracts with highly-rated counterparties. In limited circumstances, we enter into transactions with lower-rated counterparties if credit enhancement features are included.

We pledge and hold assets as collateral under CSAs for bilateral OTC derivative contracts. The collateral is realized in the event of early termination as defined in the agreements. The assets held and pledged are primarily cash and debt securities issued by the Canadian federal government and U.S. government and agencies. While we are generally permitted to sell or re-pledge the assets held as collateral, we have not sold or re-pledged any assets. Exchange-traded and cleared OTC derivatives require the posting of initial margin, as well as daily cash settlement of variation margin. The terms and conditions related to the use of the collateral are consistent with industry practice.

Further details on collateral held and pledged as well as the impact of netting arrangements are included in Note 6.A.ii.

62 Sun Life Financial Inc. December 31, 2023 Notes to the Consolidated Financial Statements The following table shows the OTC derivative financial instruments with a positive fair value split by counterparty credit rating:

(3)    The credit risk associated with derivative assets subject to master netting arrangements is reduced by derivative liabilities due to the same counterparty in the event of default or early termination. Our overall exposure to credit risk reduced through master netting arrangements may change substantially following the reporting date as the exposure is affected by each transaction subject to the arrangement.
(4)    Net replacement cost is positive replacement cost less the impact of master netting agreements.
Credit Default Swaps by Underlying Financial Instrument Credit Rating
Credit default swaps ("CDS") are OTC contracts that transfer credit risk related to an underlying referenced financial instrument from one counterparty to another. The purchaser receives protection against the decline in the value of the referenced financial instrument as a result of specified credit events such as default or bankruptcy. The seller receives a periodic premium in return for payment contingent on a credit event affecting the referenced financial instrument. CDS index contracts are those where the underlying referenced financial instruments are a group of assets. The Company enters into credit derivatives to replicate credit exposure of an underlying reference security and enhance investment returns. The credit risk ratings of the underlying reference securities for single name contracts were established in accordance with the internal rating process described in the Credit Risk Management Governance and Control section.

The following table provides a summary of the credit default swap protection sold by credit rating of the underlying reference security:

Refer to accounting policies in Note 1.
Policies after January 1, 2023 (IFRS 9)
Significant increase in credit risk
The assessment of significant increase in credit risk requires judgment. We assign counterparties a relevant internal credit risk rating grade depending on their credit quality. Changes in borrower-specific internal risk ratings is a primary indicator of significant increase in credit risk.

At each reporting date, movements between Stage 1 and Stage 2 are determined based on whether an instrument’s internal rating as at the reporting date has increased (decreased) significantly relative to the date it was initially recognized. We assess whether there has been a significant increase in credit risk for exposures since initial recognition by comparing the risk of default occurring over the remaining expected life from the reporting date and the date of initial recognition. The assessment considers borrower-specific quantitative and qualitative information without consideration of collateral, and the impact of forward-looking macroeconomic factors. Unless identified at an earlier stage, the credit risk of financial assets is deemed to have increased significantly when more than 30 days past due or moved to Watch List status and such assets are automatically migrated to Stage 2. Exposures are classified as "Watch List" when there is a moderate deterioration in credit quality, but the full payment of principal and interest is still expected to be collected, or there is an increased possibility of the exposure being impaired in the near term. No impairment charge is recorded for unrealized losses on assets related to these debtors.
Incorporation of forward-looking information
The measurement of ECL for each stage and the assessment of significant increase in credit risk considers future events and economic conditions.

The probability of default ("PD"), loss given default ("LGD") and exposure at default ("EAD") inputs used to estimate allowance for ECL are modelled based on the macroeconomic variables (or changes in macroeconomic variables) that are most closely correlated with credit losses in the relevant portfolio.

Our estimation of ECL is a discounted probability-weighted estimate that considers a minimum of three future macroeconomic scenarios (base case, upside and downside) and probability weights are attributed to each scenario. All scenarios considered are applied to all portfolios subject to ECL with the same probabilities. Our assessment of significant increase in credit risk is based on changes in internal rating as at the reporting date.

We subscribe to Moody's Analytics economic forecasting services and leverage its forward-looking macroeconomic information to model ECL.

The table below includes the key macroeconomic variables, primarily but not limited to what is provided below, and the ranges of scenarios incorporated in the model within the US and Canada.

Measurement of ECL
ECL is measured as the probability-weighted present value of expected cash shortfalls expected to result from defaults over the relevant time horizon, which is the maximum contractual period over which we are exposed to credit risk, including consideration of prepayments, and extensions.

The mechanics of the ECL calculations are outlined below and the key elements are as follows: PD, LGD, and EAD.

The PD is an estimate of the likelihood of default over a given time horizon. It is estimated as at a point in time based on historical losses, along with consideration of economic scenarios and forward-looking information.

LGD is the magnitude of the likely loss if there is a default at a given time. It is based on the difference in the present values of the contractual cash flows due and those that the lender would expect to receive, including from the realization of any collateral (net of directly attributable costs).

EAD represents the expected exposure in the event of a default. We derive the EAD from the current exposure to the counterparty and potential changes to the current amount allowed under the contract, including amortization, and prepayments.

64 Sun Life Financial Inc. December 31, 2023 Notes to the Consolidated Financial Statements An ECL estimate is produced for each individual exposure.


Relevant parameters are modelled on a collective basis using portfolio segmentation that allows for appropriate incorporation of forward-looking information. To reflect other characteristics that are not already considered through modelling, expert credit judgment can be exercised in determining the final ECL.
Qualitative adjustments or overlays
The inputs and models used for calculating ECL may not always capture all characteristics of the market at the date of the financial statements. This could be a case where a major event occurs close to the reporting date, so that the potential effects are not appropriately captured in the models and inputs. To reflect this, qualitative adjustments or overlays are occasionally made as temporary adjustments when such differences are material.

The following table shows reconciliations from the opening balance to the closing balance of the allowance for ECL by class of financial instrument.

Policy applicable after January 1, 2023 (IFRS 9)
Management assesses debt securities, mortgages and loans for objective evidence of impairment at each reporting date. We employ a portfolio monitoring process to identify assets or groups of assets that have objective evidence of impairment, having experienced a loss event or events that have an impact on the estimated future cash flows of the asset or group of assets. There are inherent risks and uncertainties in our evaluation of assets or groups of assets for objective evidence of impairment, including both internal and external factors such as general economic conditions, issuers' financial conditions and prospects for economic recovery, market interest rates, unforeseen events which affect one or more issuers or industry sectors, and portfolio management parameters, including asset mix, interest rate risk, portfolio diversification, duration matching, and greater than expected liquidity needs. All of these factors could impact our evaluation of an asset or group of assets for objective evidence of impairment.

Management exercises considerable judgment in assessing for objective evidence of impairment and, based on its assessment, classifies specific assets as either performing or into one of the following credit quality lists:

"Monitor List" — the timely collection of all contractually specified cash flows is reasonably assured, but changes in issuer-specific facts and circumstances require monitoring. No impairment charge is recorded for unrealized losses on assets related to these debtors.

"Watch List" — the timely collection of all contractually specified cash flows is reasonably assured, but changes in issuer-specific facts and circumstances require heightened monitoring. An asset is moved from the Monitor List to the Watch List when changes in issuer-specific facts and circumstances increase the possibility that a security may experience a loss event on an imminent basis. No impairment charge is recorded for unrealized losses on assets related to these debtors.

"Impaired List" — the timely collection of all contractually specified cash flows is no longer reasonably assured. For these investments that are classified as FVOCI or amortized cost, an impairment charge is recorded or the asset is sold and a realized loss is recorded as a charge to income. Impairment charges and realized losses are recorded on assets related to these debtors.

Our approach to determining whether there is objective evidence of impairment varies by asset type. However, we have a process to ensure that in all instances where a decision has been made to sell an asset at a loss, the asset is impaired.
Debt Securities
Objective evidence of impairment on debt securities involves an assessment of the issuer's ability to meet current and future contractual interest and principal payments. In determining whether debt securities have objective evidence of impairment, we employ a screening process. The process identifies securities in an unrealized loss position, with particular attention paid to those securities whose fair value to amortized cost percentages have been less than 80% for an extended period of time. Discrete credit events, such as a ratings downgrade, are also used to identify securities that may have objective evidence of impairment. The securities identified are then evaluated based on issuer-specific facts and circumstances, including an evaluation of the issuer's financial condition and prospects for economic recovery, evidence of difficulty being experienced by the issuer's parent or affiliate, and management's assessment of the outlook for the issuer's industry sector.

Management also assesses previously impaired debt securities whose fair value has recovered to determine whether the recovery is objectively related to an event occurring subsequent to the impairment loss that has an impact on the estimated future cash flows of the asset.

Asset-backed securities are assessed for objective evidence of impairment. Specifically, we periodically update our best estimate of cash flows over the life of the security. In the event that there is an adverse change in the expected cash flows, the asset is impaired. Estimating
66 Sun Life Financial Inc. December 31, 2023 Notes to the Consolidated Financial Statements future cash flows is a quantitative and qualitative process that incorporates information received from third parties, along with assumptions and judgments about the future performance of the underlying collateral.


Losses incurred on the respective mortgage-backed securities portfolios are based on loss models using assumptions about key systematic risks, such as unemployment rates and housing prices, and loan-specific information such as delinquency rates and loan-to-value ratios.
Mortgages and Loans
Objective evidence of impairment on mortgages and loans involves an assessment of the borrower's ability to meet current and future contractual interest and principal payments. In determining whether objective evidence of impairment exists, we consider a number of factors including, but not limited to, the financial condition of the borrower and, for collateral dependent mortgages and loans, the fair value of the collateral.

Mortgages and loans causing concern are monitored closely and evaluated for objective evidence of impairment. For these mortgages and loans, we review information that is appropriate to the circumstances, including recent operating developments, strategy review, timelines for remediation, financial position of the borrower and, for collateral-dependent mortgages and loans, the value of security as well as occupancy and cash flow considerations.

In addition to specific allowances, circumstances may warrant a collective allowance based on objective evidence of impairment for a group of mortgages and loans. We consider regional economic conditions, developments for various property types, and significant exposure to struggling tenants in determining whether there is objective evidence of impairment for certain collateral dependent mortgages and loans, even though it is not possible to identify specific mortgages and loans that are likely to become impaired on an individual basis.

Management also assesses previously impaired mortgages and loans to determine whether a recovery is objectively related to an event occurring subsequent to the impairment loss that has an impact on the estimated future cash flows of the asset.

Policy applicable prior to January 1, 2023 (IAS 39)
Equity Securities and Other Invested Assets
Objective evidence of impairment for equity securities and investments in limited partnerships, segregated funds, and mutual funds involves an assessment of the prospect of recovering the cost of our investment. Instruments in an unrealized loss position are reviewed to determine if objective evidence of impairment exists. Objective evidence of impairment for these instruments includes, but is not limited to, the financial condition and near-term prospects of the issuer, including information about significant changes with adverse effects that have taken place in the technological, market, economic, or legal environment in which the issuer operates, and a significant or prolonged decline in the fair value of the instruments below their cost.

We apply presumptive impairment tests to determine whether there has been a significant or prolonged decline in the fair value of an instrument below its cost, and unless extenuating circumstances exist, the instrument is considered to be impaired.
Impairment of Available-for-Sale Assets

Mortgages and Loans by Credit Rating
The credit quality of mortgages and loans is evaluated internally through regular monitoring of credit-related exposures. We use judgment and experience to determine what factors should be considered when assigning an internal credit rating, which is validated through the use of credit scoring models, to a particular mortgage or corporate loan. The internal credit ratings reflect the credit quality of the borrower as well as the value of any collateral held as security.

6.B Market Risk
Risk Description
We are exposed to market risk, which is defined as the risk that the value or future cash flows of insurance and investment contract liabilities or financial assets will fluctuate because of changes or volatility in market prices. Market risk includes equity, interest rate and spread, real estate, foreign currency, and inflation risks.
Market Risk Management Governance and Control
We employ a wide range of market risk management practices and controls as outlined below:
•Market risk governance practices are in place, including independent monitoring and review and reporting to senior management and the Risk Committee.
•Income and regulatory capital sensitivities are monitored, managed, and reported against pre-established risk appetite limits for equity, interest rate, credit spread, real estate and foreign currency risks.
•Comprehensive asset-liability management and hedging policies, programs and practices are in place.
•Regulatory solvency requirements include risk-based capital requirements and are monitored regularly.
•Product Design and Pricing Policy requires a detailed risk assessment and pricing provisions for material risks.
•Stress-testing techniques, such as FCT, are used to measure the effects of large and sustained adverse market movements.
•Insurance contract liabilities are established in accordance with Canadian actuarial standards of practice and International Financial Reporting Standards.
•Internal capital targets are established at an enterprise level to cover all risks and are above minimum regulatory and supervisory levels. Actual capital levels are monitored to ensure they exceed internal targets.

Specific market risks and our risk management strategies are discussed below in further detail.
6.B.i Equity Risk
Equity risk is the potential for financial loss arising from declines or volatility in equity market prices. We are exposed to equity risk from a number of sources.

We generate revenue in our asset management businesses and from certain insurance and annuity contracts where fees are levied on account balances that are affected directly by equity market levels. Accordingly, we have further exposure to equity risk as adverse fluctuations in the market value of such assets will result in corresponding adverse impacts on revenue and income. In addition, declining and volatile equity markets may have a negative impact on sales and redemptions (surrenders) in these businesses, and this may result in further adverse impacts on net income.

A portion of our exposure to equity risk arises in connection with benefit guarantees on segregated fund products, some participating insurance contracts, some adjustable insurance contracts, and some universal life contracts. These benefit guarantees may be triggered upon death, maturity, withdrawal or annuitization. The cost of providing these guarantees is uncertain and depends upon a number of factors, including general capital market conditions, our hedging strategies, policyholder behaviour and mortality experience, each of which may result in negative impacts on net income.

We also have direct exposure to equity markets from the investments supporting other general account liabilities, surplus, and employee benefit plans. These exposures fall within our risk-taking philosophy and appetite, and are therefore generally not hedged.

The carrying value of equities by issuer country is shown in the following table:

68 Sun Life Financial Inc. December 31, 2023 Notes to the Consolidated Financial Statements Interest rate and spread risk includes the potential for financial loss arising from changes in the value of insurance and investment contract liabilities and financial assets due to changes or volatility in interest rates or spreads.


6.B.ii Interest Rate and Spread Risk
In practice, when asset cash flows and the policy obligations they support are not matched, this may result in the need to either sell assets to meet policy payments and expenses or reinvest excess asset cash flows in unfavourable interest rate or credit spread environments. This risk is managed in our asset-liability management program.

Our primary exposure to interest rate and spread risk arises from insurance and investment contracts that contain guarantees in the form of minimum crediting rates, maximum premium rates, settlement options, guaranteed annuitization options and minimum benefits. If investment returns fall below guaranteed levels, we may be required to increase liabilities or capital in respect of these contracts. The guarantees attached to these products may be applicable to both past premiums collected and future premiums not yet received. Segregated fund contracts provide benefit guarantees that are linked to underlying fund performance and may be triggered upon death, maturity, withdrawal or annuitization. Exposure to guarantees is managed within our risk appetite limits through our asset-liability management program, which may include the use of hedging strategies utilizing interest rate derivatives such as interest rate floors, swaps, futures and swaptions. The impact of these guarantees on net income are included in the disclosed market risk sensitivities.

Significant changes or volatility in interest rates or spreads could have a negative impact on sales of certain insurance and annuity products, and adversely impact the expected pattern of redemptions (surrenders) on existing policies. Increases in interest rates or widening credit spreads may increase the risk that policyholders will surrender their contracts, potentially forcing us to liquidate assets at a loss. While we have established hedging programs in place and our insurance and annuity products often contain surrender mitigation features, these may not be sufficient to fully offset the adverse impact of changes in interest rates or spreads. Declines in interest rates or narrowing spreads can result in compression of the net spread between interest earned on investments and interest credited to policyholders. Declines in interest rates or narrowing spreads can also result in increased asset calls, mortgage prepayments, and net reinvestment of positive cash flows at lower yields, and therefore adversely impact our profitability and financial position. Negative interest rates may additionally result in losses on our cash and short-term deposits and low or negative returns on our fixed income assets impacting our profitability.

We also have direct exposure to interest rates and spreads from investments supporting other general account liabilities, surplus and employee benefit plans. Higher interest rates or wider spreads will reduce the value of our existing assets. Conversely, lower interest rates or a narrowing of spreads will result in reduced investment income on new fixed income asset purchases. These exposures fall within our risk-taking philosophy and appetite and are therefore generally not hedged.

A sustained low interest rate environment may additionally adversely impact our net income, CSM, capital, and our ability to implement our business strategy and plans. This may be realized through lower sales, less profitable new business, changes in the pattern of redemptions on existing policies, among other impacts.
6.B.iii Real Estate Risk
Real estate risk is the potential for financial loss arising from fluctuations in the value of, or future cash flows from, our investments in real estate. We are exposed to real estate risk and may experience financial losses resulting from the direct ownership of real estate investments or indirectly through fixed income investments secured by real estate property, leasehold interests, ground rents, and purchase and leaseback transactions. Real estate price risk may arise from external market conditions, inadequate property analysis, inadequate insurance coverage, inappropriate real estate appraisals, or from environmental risk exposures. We hold real estate investments that support general account liabilities and surplus, and fluctuations in value will affect our net income. A material and sustained increase in interest rates may lead to deterioration in real estate values.
6.B.iv Foreign Currency Risk
Foreign currency risk is the result of mismatches in the currency of our assets and liabilities (inclusive of capital), and cash flows. This risk may arise from a variety of sources such as foreign currency transactions and services, foreign currency hedging, investments denominated in foreign currencies, investments in foreign subsidiaries and net income from foreign operations. Changes or volatility in foreign exchange rates, including a change to currencies that are fixed in value to another currency, could adversely affect our net income.

As an international provider of financial services, we operate in a number of countries, with revenues and expenses denominated in several local currencies. In each country in which we operate, we generally maintain the currency profile of assets to match the currency of liabilities and required capital. This approach provides an operational hedge against disruptions in local operations caused by currency fluctuations. Foreign currency derivative contracts such as currency swaps and forwards are used as a risk management tool to manage the currency exposure in accordance with our Asset Liability Management Policy. As at December 31, 2023 and December 31, 2022, the Company did not have a material foreign currency risk exposure.

Changes in exchange rates can affect our net income and surplus when financial results in functional currencies are translated into Canadian dollars. Net income earned outside of Canada is generally not currency hedged and a weakening in the local currency of our foreign operations relative to the Canadian dollar can have a negative impact on our net income reported in Canadian currency. A strengthening in the local currency of our foreign operations relative to the Canadian dollar would have the opposite effect. Regulatory capital ratios could also be impacted by changes in exchange rates.
6.B.v Inflation Risk
Inflation risk is the potential for financial loss arising from changes in inflation rates. This risk results from insurance contract liabilities that are linked to market measures of inflation such as the Consumer Price Index. The primary sources for this risk exposure are from certain group and retail annuity contracts and group long term disability contracts. In these contracts, the annuity and disability benefit payments may be linked to an indexing formula containing an inflation price index. Benefit payments linked to inflation indices may also include various caps, floors and averaging mechanisms that vary across product designs.

Exposure to inflation risk is managed within our asset-liability management program, primarily by investing in inflation linked assets to match liability exposures.
Notes to the Consolidated Financial Statements     Sun Life Financial Inc. December 31, 2023 69


6.B.vi Market Risk Sensitivities
We use a variety of methods and measures to manage and quantify our market risk exposures. These include duration and key rate duration management, convexity measures, cash flow gap analysis, scenario testing, and sensitivity testing of earnings and regulatory capital ratios.

The measurement of liabilities and assets are affected by the level of equity market performance, interest rates, credit and swap spreads and other market risk variables. The following sections set out the estimated immediate impact on, or sensitivity of, our net income and OCI to certain instantaneous changes in market variables as at December 31, 2023 and December 31, 2022.

The estimated sensitivities in the tables below reflect the impact of market movements on insurance contracts and investment contracts, assets backing insurance contracts, assets backing investment contracts, assets backing the surplus segment, and seed investments in our asset management subsidiaries.

Net income sensitivities to equity and real estate market movements are driven primarily by changes in the value of investments backing general account liabilities and surplus. Net income sensitivities to interest rates and spreads are driven by the net impact on liabilities and the assets backing them. Lower interest rates or a narrowing of spreads will result in increased liabilities for insurance contracts, offset by increased values of the assets backing general account liabilities. Higher interest rates or a widening of spreads will result in decreased liabilities for insurance contracts, offset by decreased values of the assets backing general account liabilities. Further detail on the impact of changes or volatility in market prices on assets and liabilities is provided under the headings "Equity Risk", "Interest Rate and Spread Risk", and "Real Estate Risk" above.

OCI sensitivities are impacted by changes in the market value of assets classified as FVOCI. The market value of FVOCI fixed income assets, which are held primarily in our surplus and investment contract segments, increases with lower interest rates or a narrowing of spreads, and decreases with higher interest rates or a widening of spreads.

As these market risk sensitivities reflect an instantaneous impact on net income and OCI, they do not include impacts over time such as the effect on fee income in our asset management businesses.

Refer to Additional Cautionary Language and Key Assumptions Related to Sensitivities in this section for important additional information regarding these estimates.

Assumes that actual equity exposures consistently and precisely track the broader equity markets. Since in actual practice equity-related exposures differ from broad market indices (due to the impact of active management, basis risk, investments in private equity and other factors), realized sensitivities may differ significantly from those illustrated above. Sensitivities include the impact of re-balancing equity hedges for hedging programs at 2% intervals (for 10% changes in equity markets) and at 5% intervals (for 25% changes in equity markets).

December 31, 2022 amounts provided in the sensitivities tables have been adjusted to reflect these January 1, 2023 reclassifications. See Note 2 for further details on the reclassifications.

The above sensitivities were determined using a 50 basis point change in interest rates and 10% and 25% changes in our equity markets because we believe that these market shocks were reasonably possible as at December 31, 2023. Significant changes in market variables may result in other than proportionate impacts on our sensitivities.
Credit Spread and Swap Sensitivities
Credit spread sensitivities reflect the impact of changes in credit spreads on our asset and liability values (including provincial government bonds, corporate bonds, and other fixed income assets). Swap spread sensitivities reflect the impact of changes in swap spreads on swap-based derivative positions and liability values.

The following tables set out the estimated immediate impact on, or sensitivity of, our net income and OCI to certain instantaneous changes in credit spreads and our net income and OCI to certain changes in swap spreads as at December 31, 2023 and December 31, 2022.

6.B.vii Additional Cautionary Language and Key Assumptions Related to Sensitivities
Our market risk sensitivities are measures of our estimated change in net income and OCI for changes in market risk variables described above, based on market risk variables and business in force as at the reporting date. These sensitivities are calculated independently for each risk factor, generally assuming that all other risk variables stay constant. The sensitivities do not take into account indirect effects such as potential impacts on goodwill impairment or valuation allowances on deferred tax assets.

We have provided measures of our net income sensitivity to instantaneous changes in equity markets, interest rates, credit spreads, swap spreads, and real estate price levels. The cautionary language which appears in this section is applicable to all net income and OCI sensitivities.

Actual results can differ materially from these estimates for a variety of reasons, including differences in the pattern or distribution of the market shocks, the interaction between these risk factors, model error, or changes in other assumptions such as business mix, effective tax rates, policyholder behaviour, currency exchange rates and other market variables relative to those underlying the calculation of these sensitivities. The extent to which actual results may differ from the indicative ranges will generally increase with larger movements in risk variables. Our sensitivities as at December 31, 2022 have been included for comparative purposes only.

Sensitivities to interest rates and credit spreads assume a parallel shift in assumed interest rates across the entire yield curve or a parallel shift in the indicated spreads across the entire term structure, with no change to the ultimate risk-free rate or ultimate liquidity premium. Realized sensitivities may be significantly differently from those illustrated based on factors such as different terms to maturity, geographies, asset classes and derivative types, and ratings.

The sensitivities reflect the composition of our assets and liabilities as at December 31, 2023 and December 31, 2022, respectively. Changes in these positions due to new sales or maturities, asset purchases/sales, or other management actions could result in material changes to these reported sensitivities. In particular, these sensitivities reflect the expected impact of hedging activities based on the hedging programs in place as at the December 31 calculation dates. The actual impact of hedging activity can differ materially from that assumed in the estimated sensitivities due to ongoing hedge re-balancing activities, changes in the scale or scope of hedging activities, changes in the cost or general availability of hedging instruments, basis risk (i.e., the risk that hedges do not exactly replicate the underlying portfolio experience), model risk, and other operational risks in the ongoing management of the hedge programs or the potential failure of hedge counterparties to perform in accordance with expectations.

Our hedging programs may themselves expose us to other risks, including basis risk, volatility risk, and increased levels of derivative counterparty credit risk, liquidity risk, model risk and other operational risks. These factors may adversely impact the net effectiveness, costs, and financial viability of maintaining these hedging programs and therefore adversely impact our profitability and financial position. While our hedging programs are intended to mitigate these effects (e.g., hedge counterparty credit risk is managed by maintaining broad diversification, dealing primarily with highly-rated counterparties, and transacting through OTC contracts cleared through central clearing houses, exchange-traded contracts or bilateral OTC contracts negotiated directly between counterparties that include credit support annexes), residual risk, potential reported earnings and capital volatility remain.

The sensitivities are based on methods and assumptions in effect as at December 31, 2023 and December 31, 2022, as applicable. Changes in the regulatory environment, assumptions or methods used to measure assets and liabilities after those dates could result in material changes to the estimated sensitivities. Changes in market risk variables in excess of the changes illustrated may result in other than proportionate impacts.

The sensitivities reflect the CSM as at December 31, 2023 and December 31, 2022. For insurance contracts measured using the VFA, where the change in the effect of the time value of money and financial risk not arising from the underlying items adjusts the CSM, changes in the CSM balance will affect the sensitivity of income to changes in market risk variables.

For the reasons outlined above, our sensitivities should only be viewed as indicative estimates of the underlying sensitivities of each factor under these specialized assumptions, and should not be viewed as predictors of our future income and OCI. Given the nature of these calculations, we cannot provide assurance that actual impacts will be consistent with the estimates provided.

6.C Liquidity Risk
Risk Description
Liquidity risk is the possibility that we will not be able to fund all cash outflow commitments and collateral requirements as they fall due. This includes the risk of being forced to sell assets at depressed prices resulting in realized losses on sale. This risk also includes restrictions on our ability to efficiently allocate capital among our subsidiaries due to various market and regulatory constraints on the movement of funds. Our funding obligations arise in connection with the payment of policyholder benefits, expenses, reinsurance settlements, asset purchases, investment commitments, interest on debt, and dividends on common and preferred shares. Sources of available cash flow include general fund premiums and deposits, investment related inflows (such as maturities, principal repayments, investment income and proceeds of asset sales), proceeds generated from financing activities, and dividends and interest payments from subsidiaries. We have various financing transactions and derivative contracts under which we may be required to pledge collateral or to make payments to our counterparties for the decline in market value of specified assets. The amount of collateral or payments required may increase under certain circumstances (such as changes to interest rates, credit spreads, equity markets or foreign exchange rates), which could adversely affect our liquidity.
Liquidity Risk Management Governance and Control
We generally maintain a conservative liquidity position and employ a wide range of liquidity risk management practices and controls, which are described below:
•Liquidity risk governance practices are in place, including independent monitoring and review and reporting to senior management and the Risk Committee.
•Liquidity is managed in accordance with our Asset Liability Management Policy and operating guidelines.
•Liquidity contingency plans are maintained for the management of liquidity in a liquidity event.
•Stress testing is performed by comparing liquidity coverage risk metrics under a one-month stress scenario to our policy thresholds. These liquidity coverage risk metrics are measured and managed at the enterprise and legal entity levels.
•Stress testing of our collateral is performed by comparing collateral coverage ratios to our policy thresholds.
•Cash Management and asset-liability management programs support our ability to maintain our financial position by ensuring that sufficient cash flow and liquid assets are available to cover potential funding requirements. We invest in various types of assets with a view of matching them to our liabilities of various durations.
•Internal capital targets are established at an enterprise level to cover all risks and are above minimum regulatory and supervisory levels. Actual capital levels are monitored to ensure they exceed internal targets.
•We actively manage and monitor our capital and asset levels, and the diversification and credit quality of our investments.
•Various credit facilities for general corporate purposes are maintained.

We are subject to various regulations in the jurisdictions in which we operate. The ability of SLF Inc.'s subsidiaries to pay dividends and transfer funds is regulated in certain jurisdictions and may require local regulatory approvals and the satisfaction of specific conditions in certain circumstances. Through effective cash management and capital planning, SLF Inc. ensures that its subsidiaries, as a whole and on a stand-alone basis, are properly funded and maintain adequate liquidity to meet obligations, both individually and in aggregate.

Based on our historical cash flows and liquidity management processes, we believe that the cash flows from our operating activities will continue to provide sufficient liquidity for us to satisfy debt service obligations and to pay other expenses as they fall due.

6.C.i Maturity Analysis for Insurance Contracts
The following tables present the undiscounted estimated future cash flows of insurance contract and reinsurance contract held assets and liabilities on our Consolidated Statements of Financial Position. These cash flows include estimates related to the timing and payment of death and disability claims, policy surrenders, policy maturities, annuity payments, minimum guarantees on segregated fund products, policyholder dividends, amounts on deposit, commissions and premium taxes offset by contractual future premiums and fees on in-force contracts. These estimated cash flows are based on the best estimated assumptions used in the determination of insurance contract and reinsurance contract held assets and liabilities. Due to the use of assumptions, actual cash flows will differ from these estimates. Amounts payable on demand, which includes amounts on deposit, dividends on deposit, outstanding claims and policyholder account values, are included in the 1 year or less time band. The amounts included in the table differ from the carrying value of the portfolio due to discounting, RA, and LRC for contracts using the PAA.

Amounts in this table include the LIC for contracts measured using the PAA, but exclude the LRC for contracts measured using the PAA.

7. Insurance Risk Management
7.A Insurance Risk
Risk Description
Insurance risk is the uncertainty of product performance due to actual experience emerging differently than expected in the areas of mortality, morbidity and longevity. In addition, policyholder behaviour, product design and pricing, expense and reinsurance risks impact multiple risk categories, including insurance risk.
Insurance Risk Management Governance and Control
We employ a wide range of insurance risk management practices and controls, as outlined below:
•Insurance risk governance practices are in place, including independent monitoring and review and reporting to senior management and the Risk Committee.
•Income and regulatory capital sensitivities are monitored, managed and reported against pre-established risk appetite limits for policyholder behaviour, mortality, morbidity and longevity risks.
•Comprehensive Insurance Risk Policy, guidelines and practices are in place.
•The global underwriting manual aligns underwriting practices with our corporate risk management standards and ensures a consistent approach in insurance underwriting.
•Board-approved maximum retention limits are in place. Amounts issued in excess of these limits are reinsured.
•Detailed procedures, including criteria for approval of risks and for claims adjudication are established and monitored for each business segment.
•Underwriting and risk selection standards and procedures are established and overseen by the corporate underwriting and claims risk management function.
•Diversification and risk pooling is managed by aggregation of exposures across product lines, geography and distribution channels.
•We use reinsurance to limit losses, minimize exposure to significant risks and to provide additional capacity for growth.
•The Insurance Risk Policy and Investment & Credit Risk Policy establish acceptance criteria and protocols to monitor the level of reinsurance ceded to any single reinsurer or group of reinsurers.
•Reinsurance counterparty risk is monitored, including annual reporting of reinsurance exposure to the Risk Committee.
Notes to the Consolidated Financial Statements     Sun Life Financial Inc. December 31, 2023 75


•Various limits, restrictions and fee structures are introduced into plan designs in order to establish a more homogeneous policy risk profile and limit potential for anti-selection.
•Regulatory solvency requirements include risk-based capital requirements and are monitored regularly.
•The Product Design and Pricing Policy requires detailed risk assessment and pricing provision for material risks.
•Company specific and industry level experience studies and drivers of earnings analysis are monitored and factored into valuation, renewal and new business pricing processes.
•Stress-testing techniques, such as Financial Condition Testing (FCT), are used to measure the effects of large and sustained adverse movements in insurance risk factors.
•Internal capital targets are established at an enterprise level to cover all risks and are above minimum regulatory and supervisory levels.

The concentration for insurance risks is monitored geographically and its adverse effect is mitigated through a diversified product portfolio, product design, underwriting standards and practices, utilizing reinsurance as well as the Company's global operation. Specific to the reinsurance risk, the concentration is measured by aggregating the exposure to each reinsurance counterparty across all Business Groups to ensure it does not exceed a predefined risk level.

Specific insurance risks and our risk management strategies are discussed below in further detail.
7.A.i Policyholder Behaviour Risk
Risk Description
We can incur losses due to adverse policyholder behaviour relative to the assumptions used in the pricing and valuation of products regarding lapse of policies or exercise of other embedded policy options.

Uncertainty in policyholder behaviour can arise from several sources including unexpected events in the policyholder's life circumstances, the general level of economic activity (whether higher or lower than expected), changes in the financial and capital markets, changes in pricing and availability of current products, the introduction of new products, changes in underwriting technology and standards, as well as changes in our financial strength or reputation. Uncertainty in future cash flows affected by policyholder behaviour can be further exacerbated by unexpected behaviour during times of economic turbulence or at key option exercise points in the life of an insurance contract.
Policyholder Behaviour Risk Management Governance and Control
Various types of provisions are built into many of our products to reduce the impact of uncertain policyholder behaviour. These provisions include:
•Surrender charges that adjust the payout to the policyholder by taking into account prevailing market conditions.
•Limits on the amount that policyholders can surrender or borrow.
•Restrictions on the timing of policyholders' ability to exercise certain options.
•Restrictions on both the types of funds policyholders can select and the frequency with which they can change funds.
•Policyholder behaviour risk is also mitigated through reinsurance on some insurance contracts.

Internal experience studies are used to monitor, review and update policyholder behaviour assumptions as needed, which could result in updates to policy liabilities.
7.A.ii Mortality and Morbidity Risk
Mortality and morbidity risk is the risk that future experience could be unfavourable relative to the assumptions used in the pricing and valuation of products. Mortality and morbidity risk can arise in the normal course of business through random fluctuation in realized experience, through catastrophes, as a result of a pandemic, or in association with other risk factors such as product development and pricing risk. Adverse mortality and morbidity experience could also occur through systemic anti-selection, which could arise due to poor plan design, or underwriting process failure or the development of investor-owned and secondary markets for life insurance policies.

External factors could adversely affect our life insurance, health insurance, critical illness, disability, long-term care insurance and annuity businesses. Morbidity experience could be unfavourably impacted by external events, such as pandemics, increases in disability claims during economic slowdowns and increases in high medical treatment costs and growth in utilization of specialty drugs. This introduces the potential for adverse financial results.
Mortality and Morbidity Risk Management Governance and Control
Detailed uniform underwriting procedures have been established to determine the insurability of applicants and to manage exposure to large claims. These underwriting requirements are regularly scrutinized against industry guidelines and oversight is provided through a corporate underwriting and claim management function.

The Insurance Risk Policy, which is approved by the Risk Committee, sets out limits on the maximum amount of insurance risk per life that may be retained. Amounts in excess of the Board-approved maximum retention limits are reinsured. On a single life or joint-first-to-die basis our retention limit is $40 in Canada and US$40 outside of Canada. For survivorship life insurance, our maximum global retention limit is $50 in Canada and US$50 outside of Canada. In certain markets and jurisdictions, retention levels below the maximum are applied. Reinsurance is utilized for numerous products in most business segments, and placement is done on an automatic basis for defined insurance portfolios and on a facultative basis for individual risks with certain characteristics.

Concentration risk exposure is monitored on group policies in a single location. We do not have a high degree of concentration risk to single individuals or groups due to our well-diversified geographic and business mix. The largest portion of mortality risk within the Company is in North America. Individual and group insurance policies are underwritten prior to initial issue and renewals, based on risk selection, plan design, and rating techniques.

Retention limits per life vary by geographic region and amounts in excess of limits are reinsured to ensure there is no exposure to unreasonable concentration of risk.
76 Sun Life Financial Inc. December 31, 2023     Notes to the Consolidated Financial Statements


7.A.iii Longevity Risk
Risk Description
Longevity risk is the potential for losses arising from adverse changes in rates of mortality improvement relative to the assumptions used in the pricing and valuation of products. This risk can manifest itself slowly over time as socioeconomic conditions improve and medical advances continue. It could also manifest itself more quickly, for example, due to medical breakthroughs that significantly extend life expectancy. Longevity risk affects contracts where benefits or costs are based upon the likelihood of survival and higher than expected improvements in insured life expectancy could therefore increase the ultimate cost of these benefits (for example, annuities, pensions, pure endowments, some segregated funds, and specific types of health contracts).
Longevity Risk Management Governance and Control
To improve management of longevity risk, we monitor research in the fields that could result in a change in expected mortality improvement. Stress-testing techniques are used to measure and monitor the impact of extreme mortality improvement on the aggregate portfolio of insurance and annuity products.
7.A.iv Product Design and Pricing Risk
Risk Description
Product design and pricing risk is the risk a product does not perform as expected, causing adverse financial consequences. This risk may arise from deviations in realized experience versus assumptions used in the pricing of products. Risk factors include uncertainty concerning future investment yields, policyholder behaviour, mortality and morbidity experience, sales levels, mix of business, expenses and taxes. Although some of our products permit us to increase premiums or adjust other charges and credits during the life of the policy or contract, the terms of these policies or contracts may not allow for sufficient adjustments to maintain expected profitability. This could have an adverse effect on our profitability and capital position.
Product Design and Pricing Governance and Control
Our Product Design and Pricing Policy, approved by the Risk Committee, establishes the framework governing our product design and pricing practices and is designed to align our product offerings with our strategic objectives and risk-taking philosophy. Consistent with this policy, product development, design and pricing processes have been implemented throughout the Company. New products follow a stage-gate process with defined management approvals based on the significance of the initiative. Each initiative is subject to a risk assessment process to identify key risks and risk mitigation requirements and is reviewed by multiple stakeholders. Additional governance and control procedures are listed below:
•Pricing models, methods, and assumptions are subject to periodic internal peer reviews.
•Experience studies, drivers of earnings analysis, and product dashboards are used to monitor actual experience against those assumed in pricing and valuation.
•On experience rated, participating, and adjustable products, emerging experience is reflected through changes in policyholder dividend scales as well as other policy adjustment mechanisms such as premium and benefit levels.
•Limits and restrictions may be introduced into the design of products to mitigate adverse policyholder behaviour or apply upper thresholds on certain benefits.
7.A.v Expense Risk
Risk Description
Expense risk is the risk that future expenses are higher than the assumptions used in the pricing and valuation of products. This risk can arise from general economic conditions, unexpected increases in inflation, slower than anticipated growth, or reduction in productivity leading to increases in unit expenses. Expense risk occurs in products where we cannot or will not pass increased costs onto the policyholder and will manifest itself in the form of a liability increase or a reduction in expected future profits.
Expenses Risk Management Governance and Control
We closely monitor expenses through an annual budgeting process and ongoing monitoring of any expense gaps between unit expenses assumed in pricing and actual expenses.
7.A.vi Reinsurance Risk
Risk Description
We purchase reinsurance for certain risks underwritten by our various insurance businesses. Reinsurance risk is the risk of financial loss due to adverse developments in reinsurance markets (for example, discontinuance or diminution of reinsurance capacity, or an increase in the cost of reinsurance), insolvency of a reinsurer or inadequate reinsurance coverage. While reinsurance arrangements provide for the recovery of claims arising from the liabilities ceded, we retain primary responsibility to the policyholders.

Rates for our in-force reinsurance treaties can be either guaranteed or adjustable for the life of the ceded policy. Changes in reinsurance market conditions, including actions taken by reinsurers to increase rates on existing and new coverage and our ability to obtain appropriate reinsurance, may adversely impact the availability or cost of maintaining existing or securing new reinsurance capacity, with adverse impacts on our business strategies, profitability and financial position. There is a possibility of rate increases or renegotiation of some of the legacy reinsurance contracts by our reinsurers, as the global reinsurance industry continues to review and optimize their business models. In addition, changes to the regulatory treatment of reinsurance arrangements could have an adverse impact on our capital position.
Reinsurance Risk Management Governance and Control
We have an Insurance Risk Policy approved by the Risk Committee and an Investment & Credit Risk Policy approved by the Governance, Investment & Sustainability Committee, which set acceptance criteria and processes to monitor and manage the level of reinsurance ceded to any single reinsurer. These policies are regularly reviewed and approved by the relevant Board Committee to ensure the alignment with our risk appetite levels and reinsurance risk guidelines.
Notes to the Consolidated Financial Statements     Sun Life Financial Inc. December 31, 2023 77



The policies set the acceptance criteria which verify if a reinsurer qualifies as a suitable reinsurance counterparty, having the capability, expertise, governance practices and financial capacity to assume the risks being considered. In addition, a periodic due diligence is performed on the existing reinsurance counterparties, including an internal credit assessment for reinsurance counterparties with whom we have material exposure.

The exposure to each reinsurance counterparty is monitored closely to ensure that no single reinsurance counterparty represents an undue level of credit risk and does not exceed the predefined limits. In order to diversify our reinsurance risk, there is generally more than one reinsurance counterparty supporting a reinsurance pool. A summary of the reinsurance counterparty credit risk exposures is reported annually to the Risk Committee.

To further increase the reinsurance risk control, our reinsurance agreements include provisions to allow actions to be taken, such as recapture of ceded risk (at a potential cost to the Company), in the event that the reinsurance counterparty loses its legal ability to carry on business through insolvency or regulatory action.

In case of unfavourable developments in the reinsurance markets, we also have an option to discontinue or implement changes to the new sales of our products to better manage the associated risks.
7.B Sensitivity to Changes in Non-Financial Assumptions
The following table sets out the estimated immediate impact on, or sensitivity of, the CSM and net income to certain instantaneous changes in the insurance and other non-financial assumptions used in the calculation of our insurance contract liabilities, based on a starting point and business mix as at December 31, 2023 and December 31, 2022. These sensitivities are calculated independently for each risk factor, generally assuming that all other risk variables stay constant. The estimates are illustrative and different starting points for best estimate assumptions, CSM balances and business mix will result in different estimated sensitivities.

The impact on CSM is attributable to insurance contracts measured using the GMA and VFA. For insurance contracts measured using the GMA, the impact flows through the CSM at locked-in discount rates. For insurance contracts measured using the VFA, the impact flows through the CSM at current discount rates.

The impact on net income is attributable to any portion of the sensitivities for insurance contracts measured under GMA and VFA that cannot be absorbed by CSM, the full impact for insurance contracts measured under the PAA, and the difference in impact between locked-in and current discount rates for insurance contracts measured using the GMA. If current discount rates are higher than locked-in rates, this generally results in a favourable impact to net income from contracts measured using the GMA.

Total $ 8,969  $ 8,705 

Goodwill acquired in business combinations is allocated to the CGUs or groups of CGUs that are expected to benefit from the synergies of the particular acquisition.

Goodwill is assessed for impairment annually or more frequently if events or circumstances occur that may result in the recoverable amount of a CGU falling below its carrying value. The recoverable amount is the higher of fair value less costs of disposal and value in use. We use fair value less costs of disposal as the recoverable amount.

Notes to the Consolidated Financial Statements     Sun Life Financial Inc. December 31, 2023 79


We use the best evidence of fair value less costs of disposal as the price obtainable for the sale of a CGU, or group of CGUs. Fair value less costs of disposal is initially assessed by looking at recently completed market comparable transactions. In the absence of such comparables, we use either an appraisal methodology (with market assumptions commonly used in the valuation of insurance companies or asset management companies) or a valuation multiples methodology. The fair value measurements are categorized in Level 3 of the fair value hierarchy.

The most recent calculations from 2018 for certain CGUs and groups of CGUs were carried forward and used in the impairment test in the current period as: (i) the recoverable amount for these CGUs and groups of CGUs exceeded the carrying amount by a substantial margin, (ii) the assets and liabilities making up the CGUs and groups of CGUs had not changed significantly, and (iii) the likelihood that the carrying value would exceed the recoverable amount was remote, based on an analysis of events that have occurred and circumstances that have changed. The key drivers impacting the recoverable amount from 2018 are consistent with the key assumptions below.

Under the appraisal methodology, fair value is assessed based on best estimates of future income, expenses, level and cost of capital over the lifetime of the policies and, where appropriate, adjusted for items such as transaction costs. The value ascribed to new business is based on sales anticipated in our business plans, sales projections for the valuation period based on reasonable growth assumptions, and anticipated levels of profitability of that new business. In calculating the value of new business, future sales are projected for 10 to 15 years. In some instances, market multiples are used to approximate the explicit projection of new business.

The discount rates applied reflect the nature of the environment for that CGU. The discount rates used range from 9.50% to 12.50% (after tax). More established CGUs with a stronger brand and competitive market position use discount rates at the low end of the range and CGUs with a weaker competitive position use discount rates at the high end of the range. The capital levels used are aligned with our business objectives.
Under the valuation multiples methodology, fair value is assessed with reference to multiples or ratios of comparable businesses. For life insurers and asset managers, these valuation multiples and ratios may include price-to-earnings or price-to-assets-under-management measures. This assessment takes into consideration a variety of relevant factors and assumptions, including expected growth, risk, and market conditions among others. The price-to-earnings multiples used range from 10.50 to 11.50. The price-to-assets-under-management ratios used range from 1.5% to 2.0%.

Judgment is used in estimating the recoverable amounts of CGUs and the use of different assumptions and estimates could result in material adjustments to the valuation of CGUs and the size of any impairment. Any material change in the key assumptions including those for capital, discount rates, the value of new business, and expenses, as well as cash flow projections used in the determination of recoverable amounts, may result in impairment charges, which could be material.

In considering the sensitivity of the key assumptions above, management determined that there is no reasonably possible change in any of the above that would result in the recoverable amount of any of the CGUs to be less than its carrying amount.

10. Insurance Contracts
10.A Summary and Methods and Assumptions
10.A.i Summary
We sell a variety of insurance contracts that include all forms of life, health and critical illness insurance sold to individuals and groups, annuities, and segregated fund products with guarantees. We hold reinsurance contracts that transfer mortality and other risks following internal guidelines.

Insurance contracts with direct participation features are products where investments are managed on behalf of policyholders, and investment returns less a variable fee are passed through to policyholders with the insurance benefits they receive. Insurance contracts with direct participation features are measured using the VFA, and include segregated funds, unit-linked contracts, variable universal life contracts, and most participating insurance contracts. Reinsurance contracts (both issued and held) cannot be measured using the VFA.

Insurance contracts without direct participation features are eligible to use the PAA if the coverage period is one year or less, or if the result of applying the PAA is not expected to be materially different result than applying the GMA in each reporting period over the life of the contract. Insurance contracts eligible to use the PAA include most group life and health contracts and the associated reinsurance contracts held.

Other insurance contracts are measured using the GMA. This includes most individual life and health insurance contracts and annuities and the associated reinsurance contracts held.

The Consolidated Statements of Financial Position present insurance contracts issued and reinsurance contracts held as both assets and liabilities, depending on whether the portfolio is in an asset or liability position. The disclosures in this Note are for the net insurance contract asset or liability, and net reinsurance contract held asset or liability. In addition, certain disclosures in this Note exclude assets and liabilities for contracts measured using the PAA, as indicated.

The tables in this note show the insurance contracts issued and reinsurance contracts held by reportable business segment, excluding insurance contract liabilities for account of segregated fund holders. Further details on Insurance contract liabilities for account of segregated fund holders are included in Note 21. Total insurance contract liabilities, including Insurance contract liabilities for account of segregated fund holders, are $154,710 as at December 31, 2023 (December 31, 2022 — $154,433, January 1, 2022 — $175,491).

Notes to the Consolidated Financial Statements     Sun Life Financial Inc. December 31, 2023 83


10.A.ii Methods and Assumptions
General
A group of insurance contracts is measured as the total of FCF, which is the present value of future cash flows plus the risk adjustment for non-financial risk, and, for groups measured using the GMA or VFA, the CSM. In measuring the present value of future cash flows, assumptions must be made about mortality and morbidity rates, lapse and other policyholder behaviour ("policyholder behaviour"), expenses and other factors over the life of our products, and the prevailing market view of the cost of financial risk in our products. Many of these assumptions relate to events that are anticipated to occur many years in the future. Assumptions require significant judgment and regular review and, where appropriate, revision.

The RA is the compensation we require for the uncertainty related to non-financial risk in the estimates of future cash flows. This compensation is measured by discounting cash flows from applying margins to the non-financial assumptions used in the estimate of future cash flows.

The CSM represents the unearned profit that will be recognized as insurance contract services are provided.

The methods and assumptions used in the measurement of insurance contracts are reviewed regularly and are subject to external actuarial peer review.
Present Value of Future Cash Flows
Assumptions for non-financial risk variables in the present value of future cash flows are intended to be current, neutral estimates of the expected outcome as guided by Canadian accepted actuarial practice. The choice of assumptions takes into account current circumstances, past experience data from our own experience or from the industry, the relationship of past to expected future experience, anti-selection, the relationship among assumptions (including those for financial risk variables), and other relevant factors.

Assumptions for financial risk variables in the present value of future cash flows are based on current observable market prices, adjusted to account for differences between the financial risk embedded in our products and those in the corresponding observed market instrument. Where no relevant market instrument is available, we use the best information available as guided by Canadian accepted actuarial practice.
Mortality
Mortality refers to the rates at which death occurs for defined groups of people. Mortality assumptions are generally based on the past five to ten years of experience. Our experience is combined with industry experience or experience from reinsurers where our own experience is insufficient to be statistically valid. Assumed mortality rates for life insurance and annuity contracts include assumptions about future mortality improvement based on recent trends in population mortality and our outlook for future trends.
Morbidity
Morbidity refers to the rate of being unhealthy or disabled and the rates of recovery therefrom. Most of our disability insurance is marketed on a group basis. We offer critical illness policies on an individual basis in Canada and Asia, long-term care on an individual basis in Canada, and medical stop-loss insurance is offered on a group basis in the U.S. In Canada, group morbidity assumptions are based on our five-year average experience, modified to reflect any emerging trend in recovery rates. For Canadian long-term care and critical illness insurance in Canada and Asia, assumptions are developed in collaboration with our reinsurers and are largely based on their experience. In the U.S., our experience is used for both medical stop-loss and disability assumptions, with some consideration of industry or reinsurer experience.
Policyholder Behaviour
Lapse or surrender
Policyholders may allow their policies to lapse prior to the end of the contractual coverage period by choosing not to continue to pay premiums or by surrendering their policy for the cash surrender value. Assumptions for lapse or surrender experience on life insurance are generally based on our five-year average experience. Lapse or surrender rates vary by plan, age at issue, method of premium payment, policy duration and financial risk variables.
Premium payment patterns
For universal life contracts, it is necessary to set assumptions about premium payment patterns. Studies prepared by industry or the actuarial profession are used for products where our experience is insufficient to be statistically valid. Premium payment patterns usually vary by plan, age at issue, method of premium payment, policy duration and financial risk variables.
Expense
Future expenses directly attributable to the fulfillment of our insurance contracts include the costs of premium collection, claims adjudication and processing, actuarial calculations, preparation and mailing of policy statements, and related overhead. Future expense assumptions are mainly based on our recent experience using an internal expense allocation methodology. Inflationary increases assumed in future expenses are based on long-term expectations.

Acquisition expenses directly attributable to portfolios of insurance contracts include the costs of selling, underwriting and issuing insurance contracts. For new insurance contracts measured using the GMA or VFA, actual or estimated directly attributable acquisition expenses are recognized in the initial measurement of the contract. If estimates are used, the difference between estimated and actual acquisition expenses adjusts the CSM when the group of insurance contracts is closed to new contracts.
Current Discount Rates
Current discount rates are used to discount estimates of future cash flows in determining the present value of future cash flows. Current discount rates reflect the time value of money, the characteristics of the cash flows, and the liquidity characteristics of the insurance contracts.
84 Sun Life Financial Inc. December 31, 2023 Notes to the Consolidated Financial Statements The timing of cash flows is reflected by constructing a discount curve, so that each cash flow is discounted consistent with the timing of the cash flow.


Current discount rates for cash flows that do not vary based on returns on underlying items
Cash flows that do not vary at all based on the returns on any underlying items are discounted at rates that reflect the timing and currency of cash flows and the liquidity characteristics of the insurance contracts.

In constructing the discount curve, a portion is based on market information (the observable period) and beyond that period, the discount rates are estimated (the unobservable period). The observable period, which varies by currency, is the time period where information on risk-free interest rates is deep and liquid. In the unobservable period, risk-free rates are interpolated between the last observable point and an ultimate risk-free rate at year 70. The ultimate risk-free rate is estimated using historical averages as guided by Canadian accepted actuarial practice.

The currency of cash flows is reflected by using different discount curves for different currencies.

Liquidity is reflected by adding a liquidity premium to risk-free discount rates that is consistent with the liquidity characteristics of the insurance contracts. The liquidity premium in the observable period is based on the liquidity premium on assets with similar liquidity characteristics, which is estimated from the spread inherent in current market yields less a deduction for expected and unexpected credit losses. The deduction for expected and unexpected credit losses is estimated using historical rating agency data and current market conditions, and varies by asset type, quality, and duration. The liquidity premium in the unobservable period is interpolated between the last observable liquidity premium and an ultimate liquidity premium (at year 70) specific to liquid or illiquid contracts as guided by Canadian accepted actuarial practice.

The following table provides a weighted average summary of the discount curves used to present value cash flows that do not vary based on the returns on underlying items for all major products by business group:
As at December 31, 2023 December 31, 2022
1 year 5 years 10 years 30 years Ultimate 1 year 5 years 10 years 30 years Ultimate
Canada CAD 5.51% 4.67% 4.59% 4.46% 4.95% 5.36% 5.00% 5.02% 4.80% 4.65%
U.S. USD 5.84% 5.12% 5.04% 5.05% 4.95% 6.06% 5.83% 5.47% 5.33% 4.65%
Asia USD 5.89% 5.06% 5.37% 5.48% 4.95% 5.88% 5.61% 6.35% 5.38% 4.65%
Current discount rates for cash flows that vary with returns on underlying items
Discount rates for cash flows that vary directly with returns on underlying items reflect that variability. For the portion of cash flows that is a pass through of returns on underlying items to policyholders, the discount rate is such that the present value of cash flows equals the portion of the underlying items that is passed through to policyholders. For cash flows that vary, but not directly, with underlying items (e.g., financial guarantees), scenario testing may be necessary. If so, discount rates used in the scenario projections are scenario-specific and based on the projected risk-free rates in the scenario plus liquidity premiums consistent with the liquidity characteristics of the contracts being measured.
Scenario Testing
Scenario testing may be required when the relationship between cash flows and financial risk variables is non-linear, or where there are complex interdependencies among cash flows. In scenario testing of financial risk variables, future cash flows are projected for each scenario path and discounted at the scenario-specific discount rates, resulting in a present value of future cash flows for each scenario. The provision for the projected cash flows is the average of the scenario-specific values. Assumptions for non-financial risk variables are the best estimate assumptions consistent with the scenario.

Scenarios are consistent with the current market environment. Our Economic Scenario Generator calibration process produces integrated stochastic scenarios of financial risk variables (e.g., risk-free interest rates, bond fund returns, equity returns) with parameters calibrated to replicate observable market prices of financial instruments available in the market. Adjustments are made when the insurance contracts being measured are illiquid but the financial instruments to which the scenarios are calibrated to are liquid.
Risk Adjustment for Non-Financial Risk
The RA for insurance contracts issued is the compensation we require for bearing uncertainty about the amount and timing of the cash flows that arises from non-financial risk. This amount is measured as the present value of the difference between estimated future cash flows with a margin applied to non-financial assumptions and estimated future cash flows without this adjustment. Margins generally range from 5% to 20% depending on the uncertainty in the determination of the assumption. The level of uncertainty, and hence the margin chosen, varies by assumption and by line of business and other factors. Considerations that would generally lead to a choice of margin at the higher end of the range are as follows:
•The statistical credibility of our experience is too low to be the primary source of data for choosing the assumption;
•Future experience is difficult to estimate;
•The cohort of risks lacks homogeneity;
•Operational risks adversely impact the ability to estimate the assumption; or
•Past experience may not be representative of future experience and the experience may deteriorate.

Margins are generally stable over time and are revised only to reflect changes in the level of uncertainty in the assumptions. Our margins tend to be at mid-range.

The RA for reinsurance contracts held represents the amount of risk transferred to the reinsurer. This is measured as the difference between the RA on the underlying insurance contracts without reinsurance and what the RA on the underlying insurance contracts would be with reinsurance. The RA for reinsurance contracts held increases the asset or reduces the liability for reinsurance contracts held.

The RA for insurance contracts corresponds to a confidence level of approximately 80-85% overall.
Notes to the Consolidated Financial Statements     Sun Life Financial Inc. December 31, 2023 85


Contractual Service Margin
The initial and subsequent measurement of CSM is described in Note 1. Additional detail about certain components of the measurement of CSM is provided below.
Interest accretion
For insurance contracts measured using the GMA, locked-in discount rates are used to accrete interest on the CSM. The locked-in discount rate for a group of insurance contracts is the weighted average of the current discount rates at initial recognition of the contracts in the group. For groups of contracts that were in-force as at January 1, 2022, which was the start of our restated comparative period as a result of adopting IFRS 17 (refer to Note 2 for details), the locked-in discount rates are the discount rates in effect at the date of transition as the fair value approach was applied for these groups at transition.

For insurance contracts measured using the VFA, there is no accretion of interest. Rather, the CSM is adjusted by the change in our share of the fair value of underlying items.
Changes in FCF relating to future service
For insurance contracts measured using the GMA, locked-in discount rates are used to measure changes in FCF relating to future service. Changes in FCF relating to future service reflect changes in non-financial assumptions but not changes in assumptions related to financial risk.

For insurance contracts measured using the VFA, current discount rates are used to measure the change in FCF relating to future service. Changes in FCF relating to future service reflect both changes in non-financial assumptions and changes in assumptions related to financial risk.

Changes in FCF relating to future service include (Liability for Remaining Coverage only):
•All changes related to investment component payments (including current period payments);
•Changes arising from changes in assumptions used to derive the present value of future cash flows — limited to non-financial assumptions for insurance contracts measured using the GMA;
•Changes in future cash flows arising from claims in the current period; and
•For insurance contracts measured using the GMA, changes related to discretionary cash flows on some universal life and adjustable products. Discretionary cash flows are cash flows outside the guaranteed payments to the policyholder, and are described as a spread on earned rates (in the case of some universal life contracts) and in the policy on criteria for changes to adjustable policies for adjustable policies.
CSM amortization
The amount of CSM recognized as insurance revenue in each period to reflect the insurance contract services provided for a group of contracts in the period is determined by:
•Identifying the total coverage units in the group (for services in current and future periods) — based on the quantity of insurance contract services;
•Allocating the CSM at the end of the period equally to each coverage unit in the current period and expected to be provided in the future (i.e., coverage units "unitize" the services provided); then
•Recognizing in insurance revenue the amount allocated to coverage units provided in the period.

Total coverage units for services expected to be provided in future periods is the present value of projected coverage units. The present value is measured using locked-in discount rates for groups measured using the GMA and current discount rates for groups measured using the VFA.

The coverage unit for a group is based on the nature of the insurance contract services provided. Insurance contract services comprise services for providing insurance coverage and, for some contracts, investment-return or investment-related services. It does not include services related to performing functions such as claims adjudication. Where more than one type of service is provided to insurance contracts in a group, the coverage unit reflects the primary service provided.

For insurance contracts measured using the VFA, coverage units are based on the policyholder's account value or the policyholders' share of the fair value of underlying items. For insurance contracts measured using the GMA, coverage units are based on the expected claim amount (excluding any investment component) for life and health insurance contracts, and the payment due in a period for annuity contracts.

For reinsurance contracts held, CSM amortization reflects the services received in the period.

10.B.v Impact of Method and Assumption Changes
For the year ended December 31, 2023
Income impact Deferred in CSM Description
Mortality / Morbidity $ (115) $ 179  Updates to reflect mortality/morbidity experience in all jurisdictions. The largest items were favourable mortality impacts in the UK Annuities in the U.S and Group Retirement Services ("GRS") in Canada. These were offset partially by adverse mortality in In-force Management in the U.S. Mortality updates impacting CSM favourably are funded at locked-in rates that are lower than current rates resulting in a negative net income impact. Additionally, favourable morbidity impacts in Group Benefits in the U.S. were largely offset by unfavourable morbidity updates in Sun Life Health in Canada.
Expense 10  (171) Updates to reflect higher costs related to IFRS 17 infrastructure and higher cost in Canada.
Financial 163  202  Updates to various financial related assumptions including the ultimate risk-free rate.
Policyholder Behaviour (75) (274) Updates to reflect lapse and policyholder behaviour in all jurisdictions. The largest items were an adverse lapse impact in Individual Term and Universal Life in Canada, and in International, Hong Kong and Vietnam in Asia.
Model enhancements and other 107  382  Various enhancements and methodology changes. The largest items were favourable impacts from refinements to the modelling of guarantees for the Individual Par in Canada and International Universal Life in Asia, as well as modelling enhancements in Vietnam in Asia offset partially by a refinement in Group in Canada and to reinsurance and other provisions in Hong Kong in Asia.
Total (pre-tax) $ 90  $ 318 
For the year ended December 31, 2022
(restated, see Note 2)
Income impact Deferred in CSM Description

Expense (9) Updates to reflect expense experience.
Financial 24  135  Updates to various financial related assumptions.
Policyholder Behaviour (35) (30) Updates to lapse and policyholder behaviour in all jurisdictions.

10.G Role of the Appointed Actuary
The Appointed Actuary is appointed by the Board and is responsible for ensuring that the assumptions and methods used in the valuation of policy liabilities are in accordance with accepted actuarial practice in Canada, applicable legislation, and associated regulations or directives.

The Appointed Actuary is required to provide an opinion regarding the appropriateness of the policy liabilities at the statement dates. Examination of supporting data for accuracy and completeness and analysis of the assets supporting the policy liabilities are important elements of the work required to form this opinion.

The Appointed Actuary is required each year to investigate the financial condition of the Company and prepare a report for the Board. The 2023 analysis tested our capital adequacy until December 31, 2027, under various adverse economic and business conditions. The Appointed Actuary reviews the calculation of our LICAT Ratios.

Prior to June 30, 2032, the redemption price is the greater of par and a price based on the yield of a corresponding Government of Canada bond plus 0.32%; from June 30, 2032, the redemption price is par.

Fair value is determined based on quoted market prices for identical or similar instruments. When quoted market prices are not available, fair value is determined from observable market data by dealers that are typically the market makers. The fair value is categorized in Level 2 of the fair value hierarchy.
Interest expense on senior debentures was $14 for both 2023 and 2022.

The senior debentures issued by SLF Inc. are direct senior unsecured obligations and rank equally with other unsecured and unsubordinated indebtedness of SLF Inc.
12.B Innovative Capital Instruments
Innovative capital instruments consist of Sun Life ExchangEable Capital Securities ("SLEECS"), which were issued by SLCT I, established as a trust under the laws of Ontario. SLCT I issued Sun Life ExchangEable Capital Securities — Series B ("SLEECS B"), which are units representing an undivided beneficial ownership interest in the assets of that trust. SLEECS B are non-voting except in certain limited circumstances. Holders of the SLEECS B are eligible to receive semi-annual non-cumulative fixed cash distributions.

The proceeds of the issuance of the SLEECS B were used by SLCT I to purchase senior debentures of Sun Life Assurance. SLCT I is not consolidated by us. As a result, the innovative capital instruments are not reported on our Consolidated Financial Statements. However, the senior debentures issued by Sun Life Assurance to SLCT I are reported on our Consolidated Financial Statements.

The SLEECS B are structured to achieve Tier 1 regulatory capital treatment for SLF Inc. and Sun Life Assurance and, as such, have features of equity capital. No interest payments or distributions will be paid in cash by SLCT I on the SLEECS B if Sun Life Assurance fails to declare regular dividends (i) on its Class B Non-Cumulative Preferred Shares Series A, or (ii) on its public preferred shares, if any are outstanding (each, a "Missed Dividend Event"). If a Missed Dividend Event occurs, the net distributable funds of SLCT I will be distributed to Sun Life Assurance as the holder of Special Trust Securities of that trust.

If SLCT I fails to pay in cash the semi-annual interest payments or distributions on the SLEECS B in full for any reason other than a Missed Dividend Event, then, for a specified period of time, Sun Life Assurance will not declare dividends of any kind on any of its public preferred shares, and if no such public preferred shares are outstanding, SLF Inc. will not declare dividends of any kind on any of its preferred shares or common shares.

Each SLEECS B unit will be automatically exchanged for 40 non-cumulative perpetual preferred shares of Sun Life Assurance if any one of the following events occurs: (i) proceedings are commenced or an order is made for the winding-up of Sun Life Assurance; (ii) OSFI takes control of Sun Life Assurance or its assets; (iii) Sun Life Assurance’s capital ratios fall below applicable thresholds; or (iv) OSFI directs Sun Life Assurance to increase its capital or provide additional liquidity and Sun Life Assurance either fails to comply with such direction or elects to have the SLEECS B automatically exchanged ("Automatic Exchange Event"). Upon an Automatic Exchange Event, former holders of the SLEECS B will cease to have any claim or entitlement to distributions, interest or principal against SLCT I and will rank as preferred shareholders of Sun Life Assurance in a liquidation of Sun Life Assurance.

(1)    Subject to regulatory approval, SLCT I may (i) redeem any outstanding SLEECS, in whole or in part, on the redemption date specified above or on any distribution date thereafter and (ii) may redeem all, but not part of any class of SLEECS upon occurrence of a Regulatory Event or a Tax Event, prior to the redemption date specified above.
(2)    The SLEECS B may be redeemed for cash equivalent to (i) the greater of the Early Redemption Price or the Redemption Price if the redemption occurs prior to June 30, 2032 or (ii) the Redemption Price if the redemption occurs on or after June 30, 2032. Redemption Price is equal to one thousand dollars plus the unpaid distributions, other than unpaid distributions resulting from a Missed Dividend Event, to the redemption date. Early Redemption Price for the SLEECS B is the price calculated to provide an annual yield, equal to the yield of a Government of Canada bond issued on the redemption date that has a maturity date of June 30, 2032, plus 32 basis points, plus the unpaid distributions, other than unpaid distributions resulting from a Missed Dividend Event, to the redemption date.
(3)    The non-cumulative perpetual preferred shares of Sun Life Assurance issued upon an Automatic Exchange Event in respect of the SLEECS B will become convertible, at the option of the holder, into a variable number of common shares of SLF Inc. on distribution dates on or after December 31, 2032.
(4)    Holders of SLEECS B may exchange, at any time, all or part of their SLEECS B units for non-cumulative perpetual preferred shares of Sun Life Assurance at an exchange rate for each SLEECS of 40 non-cumulative perpetual preferred shares of Sun Life Assurance. SLCT I will have the right, at any time before the exchange is completed, to arrange for a substituted purchaser to purchase SLEECS tendered for surrender to SLCT I so long as the holder of the SLEECS so tendered has not withheld consent to the purchase of its SLEECS. Any non-cumulative perpetual preferred shares issued in respect of an exchange by the holders of SLEECS B will become convertible, at the option of the holder, into a variable number of common shares of SLF Inc. on distribution dates on or after December 31, 2032.

104 Sun Life Financial Inc. December 31, 2023 Notes to the Consolidated Financial Statements The authorized share capital of SLF Inc. consists of the following:


14. Share Capital
•An unlimited number of common shares without nominal or par value. Each common share is entitled to one vote at meetings of the shareholders of SLF Inc. There are no pre-emptive, redemption, purchase, or conversion rights attached to the common shares.
•An unlimited number of Class A and Class B non-voting shares, issuable in series. The Board is authorized before issuing the shares, to fix the number, the consideration per share, the designation of, and the rights and restrictions of the Class A and Class B shares of each series, subject to the special rights and restrictions attached to all the Class A and Class B shares. The Board has authorized 14 series of Class A non-voting preferred shares, 8 of which are outstanding.

The common and preferred shares of SLF Inc. qualify as capital for Canadian regulatory purposes. See Note 20.
Dividends and Restrictions on the Payment of Dividends
Under the Insurance Companies Act (Canada), SLF Inc. and Sun Life Assurance are each prohibited from declaring or paying a dividend on any of its shares if there are reasonable grounds for believing that it is, or by paying the dividend would be, in contravention of: (i) the requirement that it maintains adequate capital and adequate and appropriate forms of liquidity, (ii) any regulations under the Insurance Companies Act (Canada) in relation to capital and liquidity, and (iii) any order by which OSFI directs it to increase its capital or provide additional liquidity.

SLF Inc. and Sun Life Assurance have each covenanted that, if a distribution is not paid when due on any outstanding SLEECS issued by SLCT I, then (i) Sun Life Assurance will not pay dividends on its public preferred shares, if any are outstanding, and (ii) if Sun Life Assurance does not have any public preferred shares outstanding, then SLF Inc. will not pay dividends on its preferred shares or common shares, in each case, until the 12th month following the failure to pay the required distribution in full, unless the required distribution is paid to the holders of SLEECS. Public preferred shares means preferred shares issued by Sun Life Assurance which: (a) have been issued to the public (excluding any preferred shares held beneficially by affiliates of Sun Life Assurance); (b) are listed on a recognized stock exchange; and (c) have an aggregate liquidation entitlement of at least $200. As at December 31, 2023, Sun Life Assurance did not have outstanding any shares that qualify as public preferred shares.

The terms of SLF Inc.’s outstanding preferred shares provide that for so long as Sun Life Assurance is a subsidiary of SLF Inc., no dividends on such preferred shares are to be declared or paid if Sun Life Assurance’s minimum regulatory capital ratio falls below the applicable threshold.

In addition, under the terms of SLF Inc.’s outstanding preferred shares, SLF Inc. cannot pay dividends on its common shares without the approval of the holders of those preferred shares unless all dividends on the preferred shares for the last completed period for which dividends are payable have been declared and paid or set apart for payment.

Currently, the above limitations do not restrict the payment of dividends on SLF Inc.’s preferred or common shares.

The declaration and payment of dividends on SLF Inc.’s shares are at the sole discretion of the Board of Directors and will be dependent upon our earnings, financial condition and capital requirements. Dividends may be adjusted or eliminated at the discretion of the Board on the basis of these or other considerations.

On August 29, 2023, we launched a normal course issuer bid (the "NCIB") to purchase up to 17 million of our common shares between
August 29, 2023 and, at the latest, August 28, 2024. We implemented an automatic repurchase plan with our designated broker in order to facilitate purchases of common shares under the NCIB. Under the automatic repurchase plan, our designated broker is able to purchase common shares pursuant to the NCIB at times when we ordinarily would not be active in the market due to applicable securities laws or self-imposed blackout periods. Any common shares purchased by us pursuant to the NCIB will be cancelled or used in connection with certain equity settled incentive arrangements.

For the year ended December 31, 2023, we purchased and cancelled approximately 2.8 million common shares at an average price per share of $66.61 for a total amount of $186 under the NCIB. The total amount paid to purchase the shares pursuant to the NCIB is allocated to Common shares and Retained earnings in our Consolidated Statements of Changes in Equity. The amount allocated to Common shares is based on the average cost per common share and amounts paid above the average cost are allocated to Retained earnings.

15. Interests in Other Entities
15.A Subsidiaries
Our principal subsidiaries are Sun Life Assurance and Sun Life Global Investments Inc. Sun Life Assurance is our principal operating insurance company and holds our insurance operations in Canada, the U.S., the UK, the Philippines, Hong Kong, Indonesia and Vietnam. These insurance operations are operated directly by Sun Life Assurance or through other subsidiaries. Effective the second quarter of 2023, we completed the sale of our UK Business unit. See Note 3. Sun Life Global Investments Inc. is a non-operating holding company that holds our asset management businesses, including MFS and the group of companies under SLC Management.

We are required to comply with various regulatory capital and solvency requirements in the jurisdictions in which we operate that may restrict our ability to access or use the assets of the group and to pay dividends. Further details on these restrictions are included in Notes 14 and 20.
15.B Joint Ventures and Associates
We have interests in various joint ventures and associates that principally operate in India, Malaysia, China, and the Philippines. We also have interests in joint ventures related to certain real estate investments in Canada. Our interests in these joint ventures and associates range from 24.99% to 50%. The following table summarizes, in aggregate, the financial information of these joint ventures and associates:
As at or for the years ended December 31, 2023 2022

Carrying amount of interests in joint ventures and associates $ 1,628  $ 1,614

Other comprehensive income (loss) (37) (63)
Total comprehensive income (loss) $ 57  $ (80)

106 Sun Life Financial Inc. December 31, 2023 Notes to the Consolidated Financial Statements In 2023, we increased our investment in our joint ventures and associates by $75, primarily in Asia (2022 — $69, primarily in Canada).


During 2023, we received dividends and other proceeds relating to our joint ventures and associates of $32 (2022 — $27). We also incurred rental expenses of $19 (2022 — $17) related to leases with our joint ventures and associates, with the remaining future rental payments payable to our joint ventures and associates totaling $170 over 9 years.
15.C Joint Operations
We invest jointly in investment properties and owner-occupied properties which are co-managed under contractual relationships with the other investors. We share in the revenues and expenses generated by these properties in proportion to our investment. The carrying amount of these jointly controlled assets, which is included in Investment properties and in Other assets for owner-occupied properties, is $2,100 as at December 31, 2023 (December 31, 2022 — $2,228). The fair value of these jointly controlled assets is $2,200 as at December 31, 2023 (December 31, 2022 — $2,306).
15.D Unconsolidated Structured Entities
SLF Inc. and its subsidiaries have interests in various structured entities that are not consolidated by us. A structured entity is an entity that has been designed so that voting or similar rights are not the dominant factor in deciding who controls the entity, such as when any voting rights relate to administrative tasks only and the relevant activities are directed by means of contractual arrangements. We have an interest in a structured entity when we have a contractual or non-contractual involvement that exposes us to variable returns from the performance of the entity. Our interest includes investments held in securities or units issued by these entities and fees earned from management of the assets within these entities.

Information on our interests in unconsolidated structured entities is as follows:

(2)    Includes investments in funds managed by our joint ventures with a carrying amount of $97 (2022 — $82).
15.D.i Securitization Entities
Securitization entities are structured entities that are generally financed primarily through the issuance of debt securities that are backed by a pool of assets, such as mortgages or loans.
Third-Party Managed
Our investments in third-party managed securitization entities consist of asset-backed securities, such as commercial mortgage-backed securities, residential mortgage-backed securities, collateralized debt obligations ("CDOs"), and commercial paper. These securities are generally large-issue debt securities designed to transform the cash flows from a specific pool of underlying assets into tranches providing various risk exposures for investment purposes. We do not provide financial or other support to these entities other than our original investment and therefore our maximum exposure to loss on these investments is limited to the carrying amount of our investment. We do not have control over these investments since we do not have power to direct the relevant activities of these entities, regardless of the level of our investment.
Company Managed
We provide collateral management services to various securitization entities, primarily CDOs, from which we earn a fee for our services. The financial support provided to these entities is limited to the carrying amount of our investment in these entities. We provide no guarantees or other contingent support to these entities. We have not consolidated these entities since we do not have significant variability from our interests in these entities and we do not have any investment in these entities.
15.D.ii Investment Funds and Limited Partnerships
Investment funds and limited partnerships are investment vehicles that consist of a pool of funds collected from a group of investors for the purpose of investing in assets such as money market instruments, debt securities, equity securities, real estate, and other similar assets. The preceding table includes our investments in all investment funds, including mutual funds, exchange-traded funds, and segregated funds, and our investments in certain limited partnerships. Some of these investment funds and limited partnerships are structured entities. For all investment funds and limited partnerships, our maximum exposure to loss is equivalent to the carrying amount of our investment in the fund or partnership. Investment funds and limited partnerships are generally financed through the issuance of investment fund units or limited partnership units.
Notes to the Consolidated Financial Statements     Sun Life Financial Inc. December 31, 2023 107


Third-Party Managed
We hold units in investment funds and limited partnerships managed by third-party asset managers. Our investments in fund units and limited partnership units generally give us an undivided interest in the investment performance of a portfolio of underlying assets managed or tracked to a specific investment mandate for investment purposes. We do not have control over investment funds or limited partnerships that are structured entities since we do not have power to direct their relevant activities.
Company Managed
We hold units in Company managed investment funds and limited partnerships. We generally have power over Company managed investment funds and limited partnerships that are structured entities since we have power to direct the relevant activities of the funds and limited partnerships. However, we have not consolidated these funds and limited partnerships since we do not have significant variability from our interests in these funds and limited partnerships. We earn management fees from the management of these investment funds and limited partnerships that are commensurate with the services provided and are reported in Fee income. Management fees are generally based on the value of the assets under management. Therefore, the fees earned are impacted by the composition of the assets under management and fluctuations in financial markets. The fee income earned is included in Fund management and other asset based fees in Note 16. We also hold units in investment funds and limited partnerships managed by our joint ventures. Our share of the management fees earned is included as part of the Net income (loss) reported in Note 15.B.
15.E Consolidated Structured Entities
We control and consolidate structured entities related to the CLOs described in more detail in Note 5.A.i and investment funds managed by SLC Management and its affiliate managers which invest primarily in investment properties and entities which invest in renewable energy projects.

18.A Stock Option Plans
SLF Inc. has granted stock options to eligible employees under the Executive Stock Option Plan. These options are granted at the closing price of the common shares on the Toronto Stock Exchange ("TSX") on the grant date. The options granted under the stock option plans vest over a four-year period. All options have a maximum exercise period of 10 years. The maximum number of common shares that may be issued under the Executive Stock Option Plan is 29,525,000 shares.

The activities in the stock option plans for the years ended December 31 are as follows:
2023 2022

Exercisable, December 31 1,560  $ 57.89  1,785  $ 53.33 

The weighted average share price at the date of exercise of stock options for the year ended December 31, 2023 was $68.44 (2022 — $64.00).

Compensation expense for stock options was $8 for the year ended December 31, 2023 (2022 — $7).

The stock options outstanding as at December 31, 2023, by exercise price, are as follows:
Range of exercise prices Number of stock options (thousands) Weighted average remaining contractual life (years) Weighted average exercise price
$39.02 to $55.00
689  2.55 $ 50.34 
$55.01 to $65.00

$65.01 to $68.12
1,687  8.53 $ 67.66 
Total stock options 3,428  6.47 $ 62.54 

The weighted average fair values of the stock options, calculated using the Black-Scholes option pricing model, granted during the year ended December 31, 2023 was $11.54 (2022 — $9.64). The Black-Scholes option pricing model used the following assumptions to determine the fair value of options granted during the years ending December 31:
Weighted average assumptions 2023 2022
Risk-free interest rate 3.4  % 1.8  %
Expected volatility 23.3  % 23.7  %
Expected dividend yield 4.0  % 4.0  %
Expected life of the option (in years) 6.8  6.3 
Exercise price $ 67.68  $ 68.12 

Expected volatility is based on historical volatility of the common shares, implied volatilities from traded options on the common shares, and other factors. The expected term of options granted is derived based on historical employee exercise behaviour and employee termination experience. The risk-free rate for periods within the expected term of the option is based on the Canadian government bond yield curve in effect at the time of grant.
Notes to the Consolidated Financial Statements     Sun Life Financial Inc. December 31, 2023 109


18.B Employee Share Ownership Plan
In Canada, we match eligible employees’ contributions to the Sun Life Financial Employee Stock Plan. Employees may elect to contribute from 1% to 20% of their target annual compensation to the Sun Life Financial Employee Stock Plan. Under this plan the match is provided for employees who have met one year of employment eligibility and is equal to 50% of the employee’s contributions up to 5% of an employee’s annual compensation. The match is further capped by a one thousand five hundred dollar annual maximum. Our contributions vest immediately and are expensed.

In the U.S., the Sun Life Financial U.S. Employee Stock Purchase Plan allows eligible employees to buy shares of SLF Inc. at a 10% discount at the end of six-month offering periods. Under this plan, employees who enroll can contribute from 1% to 10% of their base salary. At the end of each period, accumulated employee amounts are used to purchase stock, with the Company financing the 10% discount. The total annual contribution, including the company discount, is limited to U.S. twenty-five thousand dollars based on its fair market value on the offering date.

We recorded an expense of $10 for the year ended December 31, 2023 (2022 — $9).
18.C Other Share-Based Payment Plans
All other share-based payment plans use notional units that are valued based on the common share price on the TSX. Any fluctuation in the common share price changes the value of the units, which affects our share-based payment compensation expense. Upon redemption of these units, payments are made to the employees with a corresponding reduction in the accrued liability. We use equity swaps and forwards to hedge our exposure to variations in cash flows due to changes in the common share price for all of these plans.

Details of these plans are as follows:
Senior Executives’ Deferred Share Unit ("DSU") Plan: Under the DSU plan, designated executives may elect to receive all or a portion of their short-term incentive award in the form of DSUs. Each DSU is equivalent in value to one common share and earns dividend equivalents in the form of additional DSUs at the same rate as the dividends on common shares. The designated executives must elect to participate in the plan prior to the beginning of the plan year and this election is irrevocable. Awards generally vest immediately; however, participants are not permitted to redeem the DSUs until after termination, death, or retirement. The value at the time of redemption will be based on the fair value of the common shares immediately before their redemption.
Sun Share Plan: Under the Sun Share plan, participants are granted units that are equivalent in value to one common share and have a grant price equal to the average of the closing price of a common share on the TSX on the five trading days immediately prior to the date of grant. Participants generally hold units for up to 36 months from the date of grant. The units earn dividend equivalents in the form of additional units at the same rate as the dividends on common shares. Under this plan, some units are performance-based that may vest or become payable if we meet specified threshold performance targets. The plan provides for performance factors to motivate participants to achieve a higher return for shareholders (performance factors are determined through a multiplier that can be as low as zero or as high as two times the number of units that vest). Payments to participants are based on the number of units vested multiplied by the average closing price of a common share on the TSX on the five trading days immediately prior to the vesting date.
Additional information for other share-based payment plans: The units outstanding under these plans and the liabilities recognized for these units in our Consolidated Statements of Financial Position are summarized in the following table:
Number of units (in thousands) Sun Shares DSUs Total
Units outstanding December 31, 2023
4,945  618  5,563 
Units outstanding December 31, 2022

$ 233  $ 43  $ 276 
Liability accrued as at December 31, 2022
$ 188  $ 44  $ 232 

Compensation expense and the Income tax expense (benefit) for other share-based payment plans for the years ended December 31 are shown in the following table. Since expenses for the DSUs are accrued as part of incentive compensation in the year awarded, the expenses below do not include these accruals. The expenses presented in the following table include increases in the liabilities for Sun Shares and DSUs due to changes in the fair value of the common shares and the accruals of the Sun Shares liabilities over the vesting period, and exclude any adjustment in expenses due to the impact of hedging.
For the years ended December 31, 2023 2022
Compensation expense $ 164  $ 43 
Income tax expense (benefit) $ (43) $ (9)
18.D Share-Based Payment Plans of MFS
Share-based payment awards within MFS are based on their own shares. Restricted share awards are settled in MFS shares and restricted stock unit awards are settled in cash. Restricted share awards and restricted stock unit awards generally vest over a four-year period and continued employment is generally the only service requirement for these awards. Holders of restricted share awards and restricted stock unit awards are entitled to receive non-forfeitable dividend equivalent payments during the vesting period at the same rate as the dividends on MFS’s shares.

Although restricted share awards are settled in shares, all of the MFS share-based awards, including outstanding MFS shares, are accounted for as cash-settled share-based payment awards due to the fact that MFS has a practice of repurchasing its outstanding shares after a specified holding period. The fair value of restricted share awards, restricted stock unit awards, and outstanding MFS shares are estimated using a market consistent share valuation model. The amount of periodic compensation expense recognized is impacted by grants of new awards, vesting, and forfeiture of unvested awards, share repurchases, changes in fair value of awards, and outstanding MFS shares. The total
110 Sun Life Financial Inc. December 31, 2023 Notes to the Consolidated Financial Statements liability accrued attributable to all MFS share-based payment plans as at December 31, 2023 was $978 ($1,020 as at December 31, 2022) which includes a liability of $780 ($811 as at December 31, 2022) for the restricted shares and outstanding MFS shares.



Compensation expense and the Income tax expense (benefit) for these awards for the years ended December 31 are shown in the following table:

Notes to the Consolidated Financial Statements     Sun Life Financial Inc. December 31, 2023 111


We have accumulated non-capital tax losses, primarily in Canada, Indonesia and Vietnam, totaling $4,388 (2022 — $4,349). The benefit of these tax losses has been recognized to the extent that it is probable that the benefit will be realized. In addition, in the U.S., we have net capital losses of $9 (2022 — $10) for which a deferred tax asset of $2 (2022 — $2) has been recognized. Unused tax losses for which a deferred tax asset has not been recognized amount to $597 as of December 31, 2023 (2022 — $696) primarily in Indonesia and Vietnam. We also have capital losses of $nil in the UK (2022 — $434) and $202 in Canada (2022 — $275) for which a deferred tax asset of $26 (2022 — $181) has not been recognized. 2022 comparatives included losses in Sun Life UK which was sold in 2023.

We will realize the benefit of tax losses carried forward in future years through a reduction in current income taxes as and when the losses are utilized. These tax losses are subject to examination by various tax authorities and could be reduced as a result of the adjustments to tax returns. Furthermore, legislative, business or other changes may limit our ability to utilize these losses.

Included in the deferred tax asset related to losses available for carry forward are tax benefits that have been recognized on losses incurred in either the current or the preceding year. In determining if it is appropriate to recognize these tax benefits, we rely on projections of future taxable profits, and we also consider tax planning opportunities that will create taxable income in the period in which the unused tax losses can be utilized.

The non-capital losses carried forward in Canada expire beginning in 2030 and the capital losses can be carried forward indefinitely. The non-capital losses in Indonesia and Vietnam can be carried forward five years. The capital losses in the U.S. can be carried forward five years.

A tax recovery of $7 arose on the sale of Sun Life UK.

Recent amendments to IAS 12 provide a mandatory temporary exception to the recognition and disclosure of information about deferred taxes arising from Pillar Two, and we have applied this temporary exception. Since the Pillar Two legislation was not effective at the reporting date, the group has no related current tax exposure. Our deferred taxes will not reflect impacts of Pillar Two while the mandatory temporary exception is applicable. The global minimum tax rules will apply to Sun Life effective January 1, 2024, however the timing of the substantive enactment of these rules in most jurisdictions where Sun Life operates is uncertain. Under the legislation, Sun Life is liable to pay a top-up tax for the difference between the effective tax rate under the Pillar Two rules on a jurisdiction-by-jurisdiction basis and the 15% minimum rate. For the jurisdictions in which Sun Life operates where the rules are considered substantively enacted, it is expected that the rules will not have a significant impact on Sun Life’s Consolidated Financial Statements when they become effective.

We recognize a deferred tax liability on all temporary differences associated with investments in subsidiaries, branches, joint ventures and associates unless we are able to control the timing of the reversal of these differences and it is probable that these differences will not reverse in the foreseeable future. As at December 31, 2023, temporary differences associated with investments in subsidiaries, branches, joint ventures and associates for which a deferred tax liability has not been recognized amount to $4,606 (2022 — $4,397).

112 Sun Life Financial Inc. December 31, 2023 Notes to the Consolidated Financial Statements Our effective income tax rate differs from the combined Canadian federal and provincial statutory income tax rate as follows:


For the years ended December 31, 2023 2022
(restated, see note 2)
% %
Total net income (loss) $ 3,469  $ 3,080 
Add: Income tax expense (benefit) 461  546 
Total net income (loss) before income taxes $ 3,930  $ 3,626 
Taxes at the combined Canadian federal and provincial statutory income tax rate $ 1,091  27.8  $ 1,006  27.8 
Increase (decrease) in rate resulting from:
Higher (lower) effective rates on income subject to taxation in foreign jurisdictions (222) (5.7) (218) (6.0)
Tax-exempt investment (income) loss (304) (7.7) (128) (3.5)
Adjustments in respect of prior years, including resolution of tax disputes (13) (0.3) (19) (0.5)
Tax (benefit) cost of unrecognized tax losses and tax credits (25) (0.7) 18  0.5 
Tax rate and other legislative changes (51) (1.3) (152) (4.2)
Other (15) (0.4) 39  0.9 
Total tax expense (benefit) and effective income tax rate $ 461  11.7  $ 546  15.0 

Statutory income tax rates in other jurisdictions in which we conduct business range from 0% to 25%, which creates a tax rate differential and corresponding tax provision difference compared to the Canadian federal and provincial statutory rate when applied to foreign income not subject to tax in Canada. Generally, earnings arising in tax jurisdictions with statutory rates lower than 27.75% reduce our tax expense and these differences are reported in Higher (lower) effective rates on income subject to taxation in foreign jurisdictions. The benefit reported in 2023 included slightly higher income in jurisdictions with low statutory income tax rates compared to 2022.

Tax-exempt investment (income) loss includes tax rate differences related to various types of investment income or losses that are taxed at rates lower than our statutory income tax rate. Examples include, but are not limited to, dividend income, capital gains arising in Canada and changes in market values including those resulting from fluctuations in foreign exchange rates.

Adjustments in respect of prior periods, including the resolution of tax disputes, relate mainly to the resolution of Canadian tax matters and the finalization of the prior year’s Canadian and U.S. tax filings. In 2022, it included the finalization of the prior year's UK tax filings.

Tax (benefit) cost of unrecognized tax losses and tax credits primarily reflects unrecognized losses in Asia, as well as the recognition of previously unrecognized deferred tax assets in the U.S. In 2022, it mainly reflected unrecognized losses in Asia and the UK.

In assessing unrecognized deferred tax assets, management has determined that it has become probable that future taxable profit will allow deferred tax assets in the U.S. to be recovered. Our U.S. subsidiaries had state net operating losses and other future deductions in computing state income taxes, for which deferred tax assets had previously not been recognized. Management has concluded that it is probable that these subsidiaries, and other historically profitable subsidiaries with which it files consolidated (unitary) state income tax returns, will generate sufficient taxable profit against which the unused state losses and deductions can be utilized. The benefit will be realized in future years through a reduction in current income taxes payable.

Tax rate and other legislative changes reflects a benefit relating to the recognition of a deferred tax asset in Bermuda. On December 27, 2023, Bermuda enacted a Corporate Income Tax regime which will apply a 15% income tax beginning on January 1, 2025. The enacted legislation provides an economic transition adjustment that aligns an entity's tax basis starting point more closely with its economic position prior to the application of the Corporate Income Tax, and can reduce Bermuda income taxes in the future. In 2022, tax rate and other legislative changes included a benefit relating to the remeasurement of our deferred tax balances as a result of a Canadian income tax rate change.

Other primarily reflects withholding taxes on distributions from our foreign subsidiaries, the benefit relating to investments in joint ventures in Asia, and the impact of taxable income attributable to NCI. In 2022, Other included the tax impact of the non-deductible goodwill impairment charge relating to the sale of Sun Life UK and the reversal of withholding taxes no longer expected to be paid.
Notes to the Consolidated Financial Statements     Sun Life Financial Inc. December 31, 2023 113


20. Capital Management

Our capital base is structured to exceed minimum regulatory and internal capital targets and maintain strong credit and financial strength ratings, while maintaining a capital efficient structure. We strive to achieve an optimal capital structure by balancing the use of debt and equity financing. Capital is managed both on a consolidated basis under the principles that consider all the risks associated with the business, as well as at the business group level under the principles appropriate to the jurisdiction in which each operates. We manage the capital for all of our international subsidiaries on a local statutory basis in a manner commensurate with their individual risk profiles.

The Board of Directors of SLF Inc. is responsible for the annual review and approval of the Company’s capital plan and capital risk policy. Management oversight of our capital programs and position is provided by the Company’s Executive Risk Committee, the membership of which includes senior management from the finance, actuarial, and risk management functions.

We engage in a capital planning process annually in which capital deployment options, fundraising, and dividend recommendations are presented to the Risk Committee of the Board of Directors. Capital reviews are regularly conducted which consider the potential impacts under various business, interest rate, and equity market scenarios. Relevant components of these capital reviews, including dividend recommendations, are presented to the Risk Committee on a quarterly basis. The Board of Directors is responsible for the approval of the dividend recommendations.

The capital risk policy is designed to ensure that adequate capital is maintained to provide the flexibility necessary to take advantage of growth opportunities, to support the risks associated with our businesses and to optimize return to our shareholders. This policy is also intended to provide an appropriate level of risk management over capital adequacy risk, which is defined as the risk that capital is not or will not be sufficient to withstand adverse economic conditions, to maintain financial strength or to allow us and our subsidiaries to support ongoing operations and to take advantage of opportunities for expansion. SLF Inc. manages its capital in a manner commensurate with its risk profile and control environment.

SLF Inc. is a non-operating insurance company and is subject to the LICAT guideline. As at December 31, 2023, SLF Inc.’s LICAT ratio exceeded the regulatory minimum target as set out by the OSFI.

Sun Life Assurance, SLF Inc.’s principal operating life insurance subsidiary in Canada, is also subject to the LICAT guideline. With a LICAT Ratio of 141% as at December 31, 2023, Sun Life Assurance's LICAT Ratio is above OSFI's Supervisory Target Total Ratio of 100% and minimum Total Ratio of 90%.

OSFI may intervene and assume control of a Canadian life insurance company if it deems the amount of available capital insufficient. Capital requirements may be adjusted by OSFI in the future, as experience develops or the risk profile of Canadian life insurers changes or to reflect other risks. Sun Life Assurance exceeded levels that would require regulatory or corrective action as at December 31, 2023 and December 31, 2022.

The Company’s regulated subsidiaries must comply with the capital adequacy requirements imposed in the jurisdictions in which they operate. In certain jurisdictions, the payment of dividends from our subsidiaries is subject to maintaining capital levels exceeding regulatory targets and/or receiving regulatory approval. We maintained capital levels above minimum local requirements as at December 31, 2023 and December 31, 2022.

In the U.S., Sun Life Assurance operates through a branch which is subject to U.S. regulatory supervision and it exceeded the levels under which regulatory action would be required as at December 31, 2023 and December 31, 2022. In the U.S., we use captive reinsurance arrangements to provide efficient financing of U.S. statutory reserve requirements in excess of those required under IFRS. Under two such arrangements, the funding of these reserve requirements is supported by a guarantee from SLF Inc.

Effective January 1, 2023, our total capital base was re-measured due to our adoption of IFRS 17. We exceeded our minimum capital requirements as at January 1, 2023. Our adjusted total capital base presented in the table below consists mainly of common shareholders’ equity, preferred shares and other equity instruments, equity in the participating account, non-controlling interests’ equity, CSM, and certain other capital securities that qualify as regulatory capital.

114 Sun Life Financial Inc. December 31, 2023 Notes to the Consolidated Financial Statements We have segregated fund products, including variable annuities, unit-linked products and variable universal life insurance policies, in Canada, the U.S., the UK, and Asia.



21. Segregated Funds
Effective the second quarter of 2023, we completed the sale of our UK Business unit. See Note 3. Under these contracts, the benefit amount is contractually linked to the fair value of the investments in the particular segregated fund. Policyholders can select from a variety of categories of segregated fund investments. Although the underlying assets are registered in our name and the segregated fund contract holder has no direct access to the specific assets, the contractual arrangements are such that the segregated fund policyholder bears the risk and rewards of the funds’ investment performance. Therefore, net realized gains and losses and other net investment income earned on the segregated funds are attributable to policyholders and not to us. However, certain contracts include guarantees from us. We are exposed to equity market risk and interest rate risk and sometimes insurance risk as a result of these guarantees. Further details on these guarantees and our risk management activities related to these guarantees are included in Notes 6 and 7.

Segregated fund contracts are classified as insurance contracts or investment contracts depending on whether there is significant insurance risk in the guarantees we provide. Segregated funds that are classified as insurance contracts are insurance contracts with direct participation features, and therefore measured using the VFA.

We derive fee income from segregated funds. Market value movements in the investments held for segregated fund holders impact the management fees earned on these funds. Fees from segregated fund contracts that are classified as investment contracts are reported as Fee Income on the Consolidated Statements of Operations. Fees from segregated fund contracts that are classified as insurance contracts are reflected in the measurement of CSM of those contracts, which is reported as revenue as insurance contract services are provided.

The segregated fund types offered, by percentage of total investments for account of segregated fund holders, were within the following ranges as at December 31, 2023 and 2022:
Type of fund %
Money market
1 to 5
Fixed income
5 to 10
Balanced
40 to 45
Equity
45 to 50

Money market funds include investments that have a term to maturity of less than one year. Fixed income funds are funds that invest primarily in investment grade fixed income securities and where less than 25% can be invested in diversified equities or high-yield bonds. Balanced funds are a combination of fixed income securities with a larger equity component. The fixed income component is greater than 25% of the portfolio. Equity consists primarily of broad-based diversified funds that invest in a well-diversified mix of Canadian, U.S. or global equities. Other funds in this category include low volatility funds, intermediate volatility funds, and high volatility funds.

Notes to the Consolidated Financial Statements     Sun Life Financial Inc. December 31, 2023 117


22. Commitments, Guarantees and Contingencies
22.A Lease Commitments
We lease offices and certain equipment. These are operating leases with rents charged to operations in the year to which they relate. Total future rental payments for the remainder of these leases total $1,269 (December 31, 2022 — $1,000). The future rental payments by year of payment are included in Note 6.
22.B Contractual Commitments
In the normal course of business, various contractual commitments are outstanding, which are not reflected in our Consolidated Financial Statements. In addition to loan commitments for debt securities and mortgages included in Note 6.A.i, we have equity, investment property, and property and equipment commitments. As at December 31, 2023, we had a total of $4,909 of contractual commitments outstanding (December 31, 2022 — $5,070). The expected maturities of these commitments are included in Note 6.
22.C Letters of Credit
We issue commercial letters of credit in the normal course of business. As at December 31, 2023, we had credit facilities of $874 available for the issuance of letters of credit (December 31, 2022 — $889), from which a total of $113 in letters of credit were outstanding (December 31, 2022 — $110).
22.D Commission on Release
Commissions on Release ("CORe") is a program designed to facilitate the transfer of blocks of business between advisors in order to provide ongoing service and advice to our Clients. We facilitate and administer these transactions including payment and collection streams. Under the CORe program, when an eligible advisor releases Clients they are servicing, we are contractually obligated to pay them the associated CORe value, based on a specified formula as stipulated in the advisor contract. The value of the CORe commitment will vary for blocks of business which have not been released by an active advisor. The occurrence of future events that will trigger an advisor to release their block of business and the value of the related CORe commitment at that future release date is difficult to predict. As a result of uncertainty in the timing of the triggering event, we cannot reliably estimate our commitment under the CORe program. Due to the nature of the program, in the normal course of business, the commitment related to the future payment to advisors on release of a block of business would be expected to be matched or partially matched by a corresponding amount related to the receivable on the assignment of blocks of business to new advisors, resulting in an immaterial impact to earnings and liquidity in any reporting period.
22.E Indemnities and Guarantees
In the normal course of our business, we have entered into agreements that include indemnities in favour of third parties, such as confidentiality agreements, engagement letters with advisors and consultants, outsourcing agreements, leasing contracts, trade-mark licensing agreements, underwriting and agency agreements, information technology agreements, distribution agreements, financing agreements, the sale of equity interests, and service agreements. These agreements may require us to compensate the counterparties for damages, losses or costs incurred by the counterparties as a result of breaches in representation, changes in regulations (including tax matters), or as a result of litigation claims or statutory sanctions that may be suffered by the counterparty as a consequence of the transaction. We have also agreed to indemnify our directors and certain of our officers and employees in accordance with our by-laws. These indemnification provisions will vary based upon the nature and terms of the agreements. In many cases, these indemnification provisions do not contain limits on our liability, and the occurrence of contingent events that will trigger payment under these indemnities is difficult to predict. As a result, we cannot estimate our potential liability under these indemnities. We believe that the likelihood of conditions arising that would trigger these indemnities is remote and, historically, we have not made any significant payment under such indemnification provisions. In certain cases, we have recourse against third parties with respect to the aforesaid indemnities, and we also maintain insurance policies that may provide coverage against certain of these claims.

In the normal course of our business, we have entered into purchase and sale agreements that include indemnities in favour of third parties. These agreements may require us to compensate the counterparties for damages, losses, or costs incurred by the counterparties as a result of breaches in representation. As at December 31, 2023, we are not aware of any breaches in representations that would result in any payment required under these indemnities that would have a material impact on our Consolidated Financial Statements.

Guarantees made by us that can be quantified are included in Note 6.A.i.
22.F Guarantees of Sun Life Assurance Preferred Shares and Subordinated Debentures
SLF Inc. has provided a guarantee on the $150 of 6.30% subordinated debentures due 2028 issued by Sun Life Assurance. Claims under this guarantee will rank equally with all other subordinated indebtedness of SLF Inc. SLF Inc. has also provided a subordinated guarantee of preferred shares issued from time to time by Sun Life Assurance, other than such preferred shares which are held by SLF Inc. and its affiliates. Sun Life Assurance has no outstanding preferred shares subject to the guarantee. As a result of these guarantees, Sun Life Assurance is entitled to rely on exemptive relief from most continuous disclosure and the certification requirements of Canadian securities laws.

Notes to the Consolidated Financial Statements     Sun Life Financial Inc. December 31, 2023 119


22.G Legal and Regulatory Proceedings
We are regularly involved in legal actions, both as a defendant and as a plaintiff. Legal actions naming us as a defendant ordinarily involve our activities as a provider of insurance protection and wealth management products, as an investor and investment advisor, and as an employer. In addition, government and regulatory bodies in Canada, the U.S., the UK, and Asia, including federal, provincial, and state securities and insurance regulators, tax authorities, and other government authorities, from time to time, make inquiries and require the production of information or conduct examinations or investigations concerning our compliance with tax, insurance, securities, and other laws.

Provisions for legal proceedings related to insurance contracts, such as for disability and life insurance claims and the cost of litigation, are included in Insurance contract liabilities in our Consolidated Statements of Financial Position. Other provisions are established outside of the Insurance contract liabilities if, in the opinion of management, it is both probable that a payment will be required and a reliable estimate can be made of the amount of the obligation. Management reviews the status of all proceedings on an ongoing basis and exercises judgment in resolving them in such manner as management believes to be in our best interest.

Two class action lawsuits have been filed against Sun Life Assurance in connection with sales practices relating to, and the administration of, individual policies issued by the Metropolitan Life Insurance Company ("MLIC"). These policies were assumed by Clarica when Clarica acquired the bulk of MLIC’s Canadian operations in 1998 and subsequently assumed by Sun Life Assurance as a result of its amalgamation with Clarica. One of the lawsuits (Fehr et al v Sun Life Assurance Company of Canada) is issued in Ontario and the other (Alamwala v Sun Life Assurance Company of Canada) is in British Columbia. The Fehr action has been certified as a class action and notice has been made to class members. Sun Life Assurance has brought a motion for summary judgment seeking to dismiss all of the claims. The other action (Alamwala v Sun Life Assurance Company of Canada) has remained largely dormant since it was commenced in 2011 and has not been certified. We will continue to vigorously defend against the claims in these actions. In connection with the acquisition of the Canadian operations of MLIC, MLIC agreed to indemnify Clarica for certain losses, including those incurred relating to the sales of its policies. Should either of the Fehr or the Alamwala lawsuits result in a loss, Sun Life Assurance will seek recourse against MLIC under that indemnity through arbitration.

An Ontario class action lawsuit has been certified against Sun Life Assurance regarding the administration of disability benefits under the Government of Canada employee benefits plan (Belec v Sun Life Assurance Company of Canada). Notice of the class action will be sent to potential class members. The Company has substantive defences to the claims and is defending this lawsuit.

Management does not believe that the probable conclusion of any current legal, regulatory or tax matter, either individually or in the aggregate, will have a material adverse effect on the Consolidated Statements of Financial Position or the Consolidated Statements of Operations.

23. Related Party Transactions
SLF Inc. and its subsidiaries, joint ventures and associates transact business worldwide. All transactions between SLF Inc. and its subsidiaries have been eliminated on consolidation. Transactions with joint ventures and associates, which are also related parties, are disclosed in Note 15. Transactions between the Company and related parties are executed and priced on an arm’s-length basis in a manner similar to transactions with third parties.
23.A Transactions with Key Management Personnel, Remuneration and Other Compensation
Key management personnel refers to the executive team and Board of Directors of SLF Inc. These individuals have the authority and responsibility for planning, directing, and controlling the activities of the Company. The aggregate compensation to the executive team and directors are as follows:

23.B Other Related Party Transactions
We provide investment management services for our pension plans. The services are provided on substantially the same terms as for comparable transactions with third parties. We also hold units of investment funds managed by certain of our joint ventures. The carrying amount of our investment in these funds is included in Note 15.D.


120 Sun Life Financial Inc. December 31, 2023 Notes to the Consolidated Financial Statements We sponsor defined benefit pension plans and defined contribution plans for eligible employees.


24. Pension Plans and Other Post-Retirement Benefits

All of our material defined benefit plans worldwide are closed to new entrants with new hires participating in defined contribution plans. Material defined benefit plans are located in Canada and the U.S. The defined benefit pension plans offer benefits based on length of service and final average earnings and certain plans offer some indexation of benefits. The specific features of these plans vary in accordance with the employee group and countries in which employees are located. In addition, we maintain supplementary non-contributory defined benefit pension arrangements for eligible employees, which are primarily for benefits which are in excess of local tax limits. As at December 31, 2014, there are no active members in the U.S. defined benefit plans continuing to accrue future service benefits. On January 1, 2009, the Canadian defined benefit plans were closed to new employees. In 2023, all assets and liabilities associated with the UK pension plans were transferred to the buyer as part of the sale of Sun Life's UK business. Canadian employees hired before January 1, 2009 continue to earn future service benefits in the previous plans, which includes both defined benefit and defined contribution components, while new hires since then are eligible to join a defined contribution plan. In addition, one small defined benefit plan in the Philippines remains open to new hires.

Our funding policy for defined benefit pension plans is to make at least the minimum annual contributions required by regulations in the countries in which the plans are offered. The defined benefit pension arrangements are governed by local pension committees. Significant plan changes require the approval of the Board of Directors of the sponsoring subsidiary of SLF Inc.

We also established defined contribution plans for eligible employees. Our contributions to these defined contribution pension plans may be subject to certain vesting requirements. Generally, our contributions are a set percentage of employees’ annual income and may be a set percentage of employee contributions, up to specified levels.

In addition to our pension plans, in Canada and the U.S., we provide certain post-retirement health care and life insurance benefits to eligible employees and to their dependents upon meeting certain requirements. Eligible retirees may be required to pay a portion of the premiums for these benefits and, in general, deductible amounts and co-insurance percentages apply to benefit payments. These post-retirement benefits are not pre-funded. In Canada, certain post-retirement health care and life insurance benefits are provided for eligible employees who retired before December 31, 2015. Eligible employees in Canada who retire after December 31, 2015 will have access to voluntary retiree-paid health care coverage. In the U.S., certain post-retirement health care and life insurance benefits are provided to eligible retirees. In the U.S., employees who were not age 50 with 10 years of service as of December 31, 2015 only have access to subsidized retiree health care coverage until eligible for Medicare. Eligible existing and future retirees and covered dependents eligible for Medicare receive an annual contribution to a health reimbursement account to be applied against individual coverage and other eligible expenses.
24.A Risks Associated with Employee Defined Benefit Plans
With the closure of the material defined benefit pension and retiree benefit plans to new entrants, the volatility associated with future service accruals for active members has been limited and will decline over time.

The major risks remaining in relation to past service obligations are increases in liabilities due to a decline in discount rates, greater life expectancy than assumed and adverse asset returns. We have significantly de-risked the investments of our material defined benefit pension plans Company-wide by shifting the pension asset mix away from equities and into more fixed income and liability-matching investments. In 2023, all asset and liabilities associated with the UK pension plans were transferred to the buyer as part of the sale of Sun Life's UK business. The target for our material funded defined benefit plans is to minimize volatility in funded status arising from changes in discount rates and exposure to equity markets.

24.C Principal Assumptions for Significant Plans
2023 2022
Canada % UK % U.S. % Canada % UK % U.S. %
To determine defined benefit obligation at end of year:
Discount rate for pension plans 4.60  n/a 5.35  5.00  4.75  5.55

Mortality rates:
Life expectancy (in years) for individuals currently at age 65:
Male 24 n/a 22 23 23 22
Female 25 n/a 23 25 25 23
Life expectancy (in years) at 65 for individuals currently at age 45:

Average duration (in years) of pension obligation 13.8 n/a 9.8 13.2 12.9 10.0
Discount Rate, Rate of Compensation Increase and Health Care Cost

The discount rate assumption used for material plans is determined by reference to the market yields, as of December 31, of high-quality corporate bonds that have terms to maturity approximating the terms of the related obligation. In countries where a deep corporate market does not exist, government bonds are used. Compensation and health care trend assumptions are based on expected long-term trend assumptions which may differ from actual results.
24.D Sensitivity of Key Assumptions
The following table provides the potential impact of changes in key assumptions on the defined benefit obligation for pension and other post-retirement benefit plans as at December 31, 2023. These sensitivities are hypothetical and should be used with caution. The impact of changes in each key assumption may result in greater than proportional changes in sensitivities.

24.E Fair Value of Plan Assets
Composition of fair value of plan assets, December 31:
2023 2022
Equity investments % %
Fixed income investments 77  % 65  %
Real estate investments 12  % 11  %
Qualifying insurance contract % 15  %
Other % %
Total composition of fair value of plan assets 100  % 100  %

The fair value of our equity investments in 2023 and 2022 are consistent with Level 1 or Level 2 fair value hierarchy. In 2023, 4% of our fixed income investments (2022 — 2%) are determined based on valuation techniques consistent with Level 1 of the fair value hierarchy.

The assets of the defined benefit pension plans are primarily held in trust for plan members, and are managed within the provisions of each plan’s investment policies and procedures. Diversification of the investments is used to limit credit, market, and foreign currency risks. We have significantly de-risked the investments of our material defined benefit pension plans by shifting the pension asset mix away from equities and into more fixed income and liability-matching investments. In 2018 and in 2021, the risk in our UK pension plan was reduced through buy-in insurance contracts, protecting the majority of pensioner benefits. The long-term investment objectives of the defined benefit pension plans are to equal or exceed the rate of growth of the liabilities. Over shorter periods, the objective of the defined benefit pension plan investment strategy is to minimize volatility in the funded status. Liquidity is managed with consideration to the cash flow requirements of the liabilities.
24.F Future Cash Flows
The following tables set forth the expected contributions and expected future benefit payments of the defined benefit pension and other post-retirement benefit plans:
Pension Post-retirement Total
Expected contributions for the next 12 months $ 47  $ 17  $ 64 
Expected Future Benefit Payments
2024 2025 2026 2027 2028 2029 to 2033

Total $ 145  $ 151  $ 156  $ 161  $ 167  $ 875 
24.G Defined Contribution Plans
We expensed $199 in 2023 (2022 — $160) with respect to defined contribution plans.

Business of Sun Life
Information about our business and operating segments, our strategy, products and methods of distribution, risk management policies and investment activities is included in the 2023 MD&A, which is incorporated by reference in this AIF.

The global financial services industry continues to evolve in response to demographic, economic, and technological trends. Specific trends that have an impact on our businesses include:

Demographic
•Major demographic shifts in developed markets include the aging of baby boomers and the growth of millennials as a client segment. Aging baby boomers are generating greater demand for retirement solutions and health solutions as they retire, while millennials seek holistic financial advice and solutions, including protection and wealth accumulation products in preparation for major life events.
•The number of High Net Worth Individuals ("HNWI") and their pool of wealth continues to expand. Within this segment, Asia will continue to be the growth engine for HNWI while North America remains the largest market. Opportunities exist for financial service providers as HNWI seek solutions that enable them to optimally transfer wealth to future generations. HNWI will continue to allocate more assets to alternatives in order to generate yield, increase total returns, and enhance diversification. Alternative asset managers are evolving their product and distribution capabilities to serve this heightened demand.
•Growing prosperity in Asia is resulting in the rise of the young middle class in many Asian countries. Growth of the middle class is expected over the long-term and a larger middle class will increase demand for a wide variety of financial products, including insurance, savings and investment vehicles. Low financial literacy has also increased the importance of financial education and advice in this region. These markets have low penetration rates and are expected to grow much faster than industrialized countries. In certain Asian markets, such as Hong Kong and China, the aging population is creating a growing opportunity for retirement and health solutions.
•Consumers are more proactively managing both physical and mental health and wellness, leading to an increased demand for accessible and affordable solutions across their health journey. This has in turn led to increased demand for tools and products to support mental health and well-being.
•Consumers have a heightened interest in sustainability. They are increasingly aligning their buying, investing, and employment decisions with companies that are leaders in sustainability. This has resulted in rising demand for sustainable investments and has influenced how companies invest as part of their investment strategy.
•Desire for greater transparency and focus on value for money spent on products and services, such as financial advice, has contributed to increased demand for low-cost asset management products, such as index funds.
•The trend of governments and employers downloading responsibility to individuals continues. This has created demand for protection, group benefits and group retirement solutions as individuals seek to fill the gaps. To help them make some of these decisions, consumers are seeking financial advice and assistance with financial planning.
•Changes in the nature of work and the continued rise of the gig economy, where work is temporary, contractual or project-based, has created an opportunity to provide solutions to workers who are left unsupported across key life needs (e.g., savings, benefits, and protection).
•Workforce expectations are also evolving as employees are demanding more holistic offerings including a hybrid and flexible way of working, and an emphasis on health and well-being, values, purpose, and culture. Companies will have to offer a unique value proposition to win and retain top talent. Simultaneously, workforce composition is shifting with Gen Z representing a greater proportion of the workforce, and baby boomer's retiring. Organizations need to focus on preservation of institutional knowledge and bringing in the necessary digital tools to enable the new workforce.

Economic
•The global economy remains in a precarious state amid rising geopolitical risk, persistent inflation and elevated interest rates. Economic activity still remains below pre-pandemic levels and the pace of recovery will be moderate with divergent recovery across economies.
•Global headline inflation is expected to steadily decline in the coming years from its peak. Individual and business purchasing power continues to be limited with rising credit risk. Many firms are therefore drawing down cash buffers as earnings moderate and as debt servicing costs continue to be high which may reduce the available capital for some institutions.
•Persistent inflation and elevated interest rates are leading to changing investor sentiment and strategies. Many investors are looking towards traditional fixed income products given high yields, and others are seeking inflationary protection through inflation-hedged investments or alternatives.
•Equity market volatility, which can be attributed to several factors such as economic growth, higher inflation, and interest rates changes, can lead to impacts on net flows and assets under management for asset management and wealth businesses. Generally, when global equity markets decline, asset management and wealth businesses also experience declines in earnings.

             Annual Information Form 2023
Technological
•Digital adoption continues to grow rapidly as consumers spend an increasing amount of time online for everyday needs (e.g., social, shopping, and banking). An increase in mobile usage is an especially important part of this shift. Omni-channel capabilities are also important to create a consistent Client experience across channels and to serve Clients in their channel of choice.
•Increasing personalization using data and analytics is allowing companies to create a frictionless digital user experience as they can better engage with Clients and meet their needs.
•Generative AI stands poised to redefine the future of financial services by enabling businesses to tailor products specifically to the customer, transforming the employee and advisor experience, reduce costs and optimise existing operations.
•Consumers are becoming more concerned about the protection and use of their data in an environment of increasing collection and data use, and more wide-spread data breaches. Meeting those Client concerns and expectations will be key to maintaining their trust and continued digital engagement. Increased adoption of AI also calls for an increased focus on improving cyber security and risk management.
•A desire for a more transparent and accessible financial services experience has led to the rise of digital currencies, smart contracts, and decentralized finance ("DeFi"). Central Banks and financial institutions are exploring the use of digital currencies which may lead to disruption of the traditional banking sector. Increased demand for DeFi may increase competition from new/existing players, offering more accessible products through new distribution channels.
•Businesses have accelerated the use of digital technology to allow for remote and hybrid work. Companies may rely more heavily on these digital tools and shift more of their workforce to remote work. This, in turn, may have an impact on the commercial real estate market.

Competition
The markets in which Sun Life participates are highly competitive. We compete against other insurance companies, banks, asset managers, mutual fund companies, financial planners, managed care companies, and other financial services and benefits providers. Frequently, competition is based on factors including price, the ability to provide value-added products and services, financial strength and consistent delivery of an excellent experience to distributors and Clients through both traditional and more innovative digital channels.

Evolving regulatory requirements, economic volatility, rising geopolitical uncertainty and the evolution of Client needs and requirements continue to be challenges for our industry and have forced insurers and financial services providers to review their businesses, re-focus their operations and, in some cases, discontinue or divest non-core lines of business, as well as acquire businesses with higher growth potential.

We face increased competition from new market entrants, including non-traditional service providers such as insurtech, healthtech and fintech companies. The acceleration of digital brought by the COVID-19 pandemic led to an increase in this trend, and a further rise of new market entrants with disruptive digital business models. In addition, incumbents are increasingly partnering with start-ups to compete in new and innovative ways. Both trends could challenge existing insurance, health, asset management and wealth management business models. Furthermore, certain large technology companies have selectively entered the financial services and health care markets by leveraging their large customer base, strong user experience capabilities, deep pools of data and digital ecosystems offering interconnected services. In response to these trends, Sun Life continues to explore new business models and seek strategic partnerships that will drive our businesses forward.

In Canada, open banking is emerging as a potential disruptor for banks and other financial institutions. Under open banking, clients of banks, fintechs or other financial institutions would be able to ask for their personal data to be securely transferred or made available to an authorized third-party service provider, such as a fintech or another financial institution. The federal government plans to introduce a legislation in 2024 to drive the broad developments of open banking. We are continuing to monitor how this development will affect the financial services landscape and Sun Life.

In addition to closely monitoring potential business disruptors, we also continuously adapt by making investments in technology and advanced analytics, building digital services and tools, and through the extension of our product offerings. Below are some examples of how we are adapting in these areas:
•Digitizing current interactions and processes: Web and mobile functionality (e.g., e-Applications, e-claims); facilitating virtual interactions (e.g., video meetings, e-signatures); digital benefits enrollment in the U.S. and for small businesses in Canada; digitally enabled distribution (e.g., digitally empowered Advisors and Bancassurance in Asia, Direct to Consumer digital in Canada through Prospr).
•Using data and analytics to be personal, predictive and proactive: Digital coach Ella in Canada; Maxwell Health, a digital benefits marketplace in the U.S.; predictive models for advisor recruiting and Client retention in Asia
Sun Life Financial Inc. | sunlife.com                                           6

             Annual Information Form 2023
•Building new business models: Lumino Health, which allows all Canadians to access provider search and discover innovative health solutions; working with bancassurance partners in Asia to offer digital sales; further expanding our role in the health care ecosystem in the U.S. through the acquisition of PinnacleCare
•Building a partnership ecosystem: Making strategic investments and acquisitions (e.g., Dialogue, a leading virtual health care provider in Canada; Pillway, a tech-first, full service digital pharmacy; Bowtie, Hong Kong's first online-only insurer); investing in technologies to connect with partners and drive global growth.

The markets in which we compete are diverse and at different stages of development:
•In Canada, the financial services industry is relatively mature and the three largest life insurance companies serve more than two-thirds of the Canadian life insurance and group benefits markets. In the wealth space, we also face competition from Canadian retail banks and investment dealers and from emerging disruptors such as "robo-advisors". In the health space, we face competition from in-market insurers but also indirect competitors, as companies look for ways to complement the public health system.
•In the United States, the largest insurance market in the world, the market is more fragmented and characterized by a large number of competitors. We face strong competition from established players in the group life and disability, dental, vision, stop-loss, and voluntary markets, all of which are markets with a number of competitors. In the turnkey disability market, there is one other primary competitor and competition is expected to remain stable.
•In Asia, the life insurance markets in countries where we participate are still evolving. The growth potential for insurance in Asian markets has created strong competition from both domestic and international insurers. We are observing the larger pan-Asian insurers grow at the fastest rate, with consolidation occurring in many markets. Additionally, some of the Asian markets that we operate in have foreign ownership restrictions, which may place constraints on our ability to operate or grow in these markets. In the international High Net Worth ("HNW") life insurance market (which for Sun Life operates out of our Asia business group), competition is increasing from the main competitors who operate in this business.
•In Asset Management, despite some consolidation, we face strong competition from a variety of players including large global asset managers, small local managers specializing in niche markets/products, multi-national and local banks as well as other insurance companies. In addition, there has been a trend among retail and institutional investors towards lower-cost passive investment products, including index and other types of exchange-traded funds, which has led to a decreased allocation of investor assets to active investment strategies. At the same time, there has been an increased demand for fixed-income, liability-driven investing and yield-oriented alternative products among institutional and HNW investors. To meet the increased demand for alternative assets, traditional asset managers are increasingly acquiring alternative assets, while alternative managers are deepening focus on the retail HNW market.

Seasonality
Some of our businesses are subject to seasonal factors. In Canada, sales of investment products spike during the first quarter of the year due to a contribution deadline for Registered Retirement Savings Plans. Timing of sales campaigns also influences sales of individual products in Canada and Asia. In the U.S., the sales pattern of our group life and health business largely reflects the renewal timing of employee benefit plans of our corporate Clients, many of which begin on January 1 each year. This often results in higher sales in the fourth quarter. In India, the sales of individual insurance products usually peak in the first quarter of each year due to tax planning by Clients. Overall, the impact of seasonal trends is not material to Sun Life.

Sustainability
Our sustainability ambition is to maximize our positive impact and ensure the resiliency of our organization, in support of our Purpose of helping Clients achieve lifetime financial security and live healthier lives. We aim to create competitive advantage and differentiation for our business through the following focus areas of our sustainability plan:

Increasing financial security: We aspire to increase the lifetime financial security of our Clients, employees and communities. We’re increasing access to and use of insurance and wealth products, and empowering and educating people to improve financial security outcomes.

In 2023, we continued to reach and engage people across the globe through programming, innovation, advice and advocacy. Our aim is to increase their financial security, well-being and resilience.

Fostering healthier lives: We aspire to improve health and wellness outcomes for our Clients, employees and communities. We're improving access to and use of health insurance and health care, and empowering people to navigate and manage their health journey to improve health outcomes. Our investments in community health complement these efforts.

In 2023, we invested in technology and formed strategic partnerships to help Clients access health care where and when they need it. Access to care is also about affordability and removing barriers for underserved communities. We expanded the number of programs that help bring affordable health and dental care solutions to lower income individuals and families.

Advancing sustainable investing: We aspire to deliver sustainable returns for Clients and drive the transition to a low-carbon, inclusive economy. We manage assets with material environmental, social and governance ("ESG") factors embedded in our investment processes and offer our Clients sustainable investing opportunities. In addition, we invest our own assets in ways that support a low-carbon and more inclusive economy.

Sun Life has made progress on its aim to be a leader in sustainable investing in 2023. We made good progress towards our goal of $20 billion in new sustainable investments from 2021 to 2025 across General Account and Client investments, which are managed by SLC Management. Investments include, but are not limited to, renewable energy, energy efficiency, sustainable buildings, clean transportation, water management, and social infrastructure projects. We ended 2022 with $14.2 billion invested towards this target and will report 2023 progress in our annual Sustainability Report, available at sunlife.com/sustainability in March 2024.

Building resilience to climate change: We are committed to being part of the climate solution. We’re decarbonizing our business and engaging with our stakeholders to support the transition to a low-carbon economy. Meaningful climate action is essential to achieving our Purpose and ensuring the resiliency of our business.

Sun Life has set a goal to achieve net-zero GHG emissions by 2050 for both its investments and operations. For our operations, we have set an interim target of a 50% absolute reduction of GHG emissions by 2030, relative to 2019(1). As an asset owner, Sun Life plans to achieve net-zero GHG emissions by 2050 for investments in its general account. Our approach for achieving net-zero emissions in the general account focuses on asset classes where we have access to quality data, established net-zero emissions methodologies and where we believe we can have the biggest real-world impact in reducing emissions. We use the Partnership for Carbon Accounting Financials (“PCAF”) Part A (Financed Emissions) methodology for asset classes where there is industry guidance and we have the ability to report. Refer to Sun Life's Net Zero by 2050 report(2) for details and our latest updates.

Our sustainability plan builds from our foundation of operating as a Trusted and Responsible Business. We aspire to be a responsibly-managed business that is Client-focused, competitive, forward-thinking and sustainable for the long term.

To have a resilient, sustainable business, diversity and inclusion must serve as a catalyst. In 2020, Sun Life reinforced its commitment to diversity, equity and inclusion by taking a firm stance for equality, social change and justice to support underrepresented communities. Sun Life continues to work towards its aspirational goals of 25% underrepresented ethnicities in Vice-President (VP)+ roles in North America, and gender parity in VP+ roles globally, by 2025. In 2021, Sun Life became the first major insurance company to pursue the Progressive Aboriginal Relations ("PAR") certification(3) a program of the Canadian Council for Aboriginal Business. In 2023, we completed Phase 2 of the program.

We support and participate in several sustainability-related forums, meetings and discussions with a range of external stakeholders. Sun Life ranked among the Corporate Knights' 2024 Global 100 Most Sustainable Corporations in the World. This was the 15th consecutive year Sun Life was named to the ranking. Sun Life was also included on the Dow Jones Sustainability Index - North America and continues to be a constituent in the FTSE4Good Index.
(1) Emissions resulting from global corporate offices and data centres as well as from business travel, inclusive of majority-owned Sun Life affiliate companies. All emissions reporting is aligned to the GHG Protocol Corporate Accounting and Reporting Standard using the financial control approach.

The dividends declared by SLF Inc. in the three years ended December 31, 2023 are set out in the 2023 MD&A under the heading Capital and Liquidity Management - Shareholder Dividends, which is incorporated by reference in this AIF.

The Insurance Act prohibits the declaration or payment of dividends on shares of an insurance company if there are reasonable grounds for believing a company does not have, or the payment of the dividend would cause the company not to have, adequate capital or liquidity, or upon any direction made by the Superintendent. The Insurance Act also requires that an insurance company notify the Superintendent of the declaration of a dividend at least fifteen days before the dividend payment date.

As a holding company, SLF Inc. depends primarily on the receipt of funds from its subsidiaries to pay shareholder dividends, interest payments and operating expenses. The source of these funds is primarily dividends and capital repayments that SLF Inc. receives from its subsidiaries. The inability of its subsidiaries to pay dividends or return capital in the future may materially impair SLF Inc.'s ability to pay dividends to shareholders or to meet its cash obligations. Additional information concerning legislation regulating the ability of SLF Inc.'s subsidiaries in Canada, the U.S. and Asia to pay dividends or return capital can be found in this AIF under the heading Regulatory Matters.

SLF Inc. and Sun Life Assurance have each covenanted that, if a distribution is not paid when due on any outstanding Sun Life ExchangEable Capital Securities ("SLEECS") issued by Sun Life Capital Trust, Sun Life Assurance will not pay dividends on its Public Preferred Shares, if any are outstanding. If Sun Life Assurance does not have any Public Preferred Shares, then SLF Inc. will not pay dividends on its preferred shares or Common Shares until the twelfth month following the failure to pay the required distribution in full, unless the required distribution is paid to the holders of the SLEECS. Public Preferred Shares means preferred shares issued by Sun Life Assurance which: (a) have been issued to the public (excluding any preferred shares held beneficially by affiliates of Sun Life Assurance); (b) are listed on a recognized stock exchange; and (c) have an aggregate liquidation entitlement of at least $200 million. Sun Life Assurance has not issued any shares that qualify as Public Preferred Shares as at the date of this AIF.

The terms of SLF Inc.'s outstanding Class A Preferred Shares provide that for so long as Sun Life Assurance is a subsidiary, no dividends on such preferred shares may be declared or paid if Sun Life Assurance’s minimum regulatory capital ratio falls below the applicable threshold.

SLF Inc.'s Class A Preferred Shares, senior unsecured debentures, and subordinated unsecured debentures are rated by independent rating agencies. Security ratings assigned to securities by the rating agencies may be subject to revision or withdrawal at any time by the applicable rating agency and are not a recommendation to purchase, hold or sell these securities as such ratings do not comment as to market price or suitability for a particular investor. Security ratings are intended to provide investors with an independent measure of the credit quality of an issue of securities.

             Annual Information Form 2023
SLF Inc. has made payments in the ordinary course to DBRS and Standard and Poor's ("S&P") in connection with the assignment of ratings on the securities of SLF Inc. In addition, SLF Inc. has made customary payments to A.M. Best, DBRS and S&P in respect of certain other services provided to SLF Inc. by the applicable rating agencies during the last two years.

The descriptions of the ratings below are sourced from public information as disclosed by each rating agency.
A.M. Best
A.M. Best’s issue credit rating ("IR") provides an opinion of credit quality assigned to issues that gauges the ability to meet the terms of the obligations and can be issued on a long- or short-term basis. An IR assigned to a specific issue is A.M. Best’s opinion of the issuer’s ability to meet the ongoing financial obligations to security holders when due. As such, an IR is an opinion regarding the relative future credit risk. Credit risk is the risk that a debt issuer may not meet its contractual financial obligations as they come due. The rating does not address any other risk, including, but not limited to, liquidity risk, market value risk or price volatility of rated obligations.

A.M. Best assigns long-term IR in a range of rating categories from "aaa" to "c". Ratings from "aa" to "ccc" may be enhanced with a "+" (plus) or "-" (minus) to indicate whether credit quality is near the top or bottom of a category. The absence of either a plus or minus designation indicates the rating is in the middle of the category.

SLF Inc.’s Subordinated Unsecured Debentures have been assigned "a-" ratings. An "a" rating denotes an issuer’s excellent ability to meet the terms of the obligation.

SLF Inc.’s Class A Preferred Shares have been assigned "bbb+" ratings. A "bbb" rating denotes an issuer’s good ability to meet the terms of the obligation, however, the issue is more susceptible to changes in economic and other conditions.
DBRS
The DBRS long-term rating scale provides an opinion on the risk of default. That is, the risk that an issuer will fail to satisfy its financial obligations in accordance with the terms under which an obligation has been issued. Ratings are based on quantitative and qualitative considerations relevant to the issuer, and the relative ranking of claims. DBRS assigns long-term ratings in a range from AAA to D, and "(high)" and "(low)" designations indicate standing within the major rating categories. The absence of either a "(high)" or "(low)" designation indicates the rating is in the middle of the category. There are no "(high)" or "(low)" designations for AAA and D ratings.

SLF Inc.’s Subordinated Unsecured Debentures and LRCNs have been assigned A and A (low) ratings, respectively. A ratings, reflecting a good credit quality, are assigned to issues when the capacity for the payment of financial obligations is substantial, but of lesser credit quality than AA, and the issue may be vulnerable to future events, but qualifying negative factors are considered manageable.

DBRS assigns ratings for preferred shares in a range from Pfd-1 to D. Reference to "high" and "low" designations indicate standing within the major rating categories. The absence of either a "(high)" or "(low)" designation indicates the rating is in the middle of the category. There are no "(high)" or "(low)" designations for D ratings. The DBRS preferred share rating scale is used in the Canadian securities market and is meant to give an indication of the risk that a borrower will not fulfill its full obligations in accordance with the terms under which the relevant preferred shares were issued, with respect to both dividend and principal commitments. SLF Inc.’s Class A Preferred Shares have been assigned a Pfd-2 (high) rating, the second highest among rating categories used by DBRS. Preferred shares rated Pfd-2 are generally of good credit quality. Protection of dividends and principal is still substantial, but earnings, the balance sheet and coverage ratios are not as strong as Pfd-1 rated companies.
Fitch
Fitch’s ratings of individual securities or financial obligations of a corporate issuer address relative vulnerability to default on an ordinal scale.

Fitch assigns long-term ratings for debt and preferred shares in a range from AAA to C. The modifiers + or - may be appended to a rating to denote relative status within major rating categories. The absence of either a plus or minus designation indicates the rating is in the middle of the category. Such modifiers are not added to the AAA rating or to ratings below CCC.

SLF Inc.’s Subordinated Unsecured Debentures have been assigned A- ratings. An A rating denotes expectations of low credit risk and the capacity for payment of financial commitments is considered strong. This capacity may, nevertheless, be more vulnerable to adverse business or economic conditions than is the case for higher ratings. SLF Inc.’s LRCNs and Class A Preferred Shares have been assigned a BBB rating. A BBB rating indicates that expectations of credit risk are currently low and the capacity for payment of financial commitments is considered adequate but adverse business or economic conditions are more likely to impair this capacity.

             Annual Information Form 2023
Standard & Poor's
An S&P issue credit rating is a forward-looking opinion about the creditworthiness of an obligor with respect to a specific financial obligation. The opinion reflects S&P's view of the obligor's capacity and willingness to meet its financial commitments as they come due, and may assess terms, such as collateral security and subordination, which could affect ultimate payment in the event of default.

S&P’s long-term credit ratings for securities are based, in varying degrees, on S&P's analysis of the following considerations:
•Likelihood of payment - capacity and willingness of the obligor to meet its financial commitment on an obligation in accordance with the terms of the obligation;
•Nature of and provisions of the obligation and the promise imputed by S&P; and
•The protection afforded by, and relative position of, the obligation in the event of bankruptcy, reorganization, or other arrangement under the laws of bankruptcy and other laws affecting creditors' rights.

These ratings are an assessment of default risk, but may incorporate an assessment of relative seniority or ultimate recovery in the event of default. Junior obligations are typically rated lower than senior obligations, to reflect the lower priority in bankruptcy.

S&P assigns long-term ratings in a range from AAA to D. The ratings from AA to CCC may be modified by the addition of a plus (+) or minus (-) sign to show relative standing within the major rating categories. The absence of either a plus or minus designation indicates the rating is in the middle of the category.

SLF Inc.’s Subordinated Unsecured Debentures and LRCNs have been assigned A and A- ratings, respectively. An A rating category indicates that the obligor’s capacity to meet its financial commitment on the obligation is strong.

S&P has Canadian and global rating scales for preferred shares. S&P assigns ratings for Canadian preferred shares in a range from P-1 to D on the Canadian scale and from AA to D on the global rating scale. S&P uses "high" and "low" designations to indicate standing within the major rating categories on the Canadian rating scale and plus or minus designations to indicate the relative standing of securities within a particular rating category on the global rating scale. The absence of either a "high" and "low" or a plus or minus designation indicates the rating is in the middle of the category. There are no plus and minus or "high" and "low" designations for rating categories below P-5/CCC, and no plus designation for an AA rating category.

S&P’s preferred share rating on the Canadian scale is a forward-looking opinion about the creditworthiness of an obligor with respect to a specific preferred share obligation issued in the Canadian market, relative to preferred shares issued by other issuers in the Canadian market. There is a direct correspondence between the specific ratings assigned on the Canadian preferred share scale and the various rating levels on the global debt rating scale of S&P. S&P presents an issuer's preferred share ratings on both the global rating scale and on the Canadian national scale when listing the ratings for a particular issuer.

SLF Inc.’s Class A Preferred Shares have been assigned a P-1 (low) rating on the Canadian scale, which corresponds to an A- rating on the global scale. An A rating category indicates that the obligor’s capacity to meet its financial commitment on the obligation is strong.

To the knowledge of SLF Inc., as at December 31, 2023, SLF Inc.'s directors and executive officers, as a group, owned, directly or indirectly, or had voting control or direction over 118,124 Common Shares of SLF Inc., or less than 1% of the total Common Shares outstanding.

Code of Conduct
We have built a strong corporate culture founded on ethical behaviour, high business standards, integrity and respect. The Board establishes the "tone from the top" and makes every effort to ensure that Senior Management consists of people who create and sustain a culture of integrity throughout the organization. Questions about this culture are included in our Board's, committee and peer effectiveness surveys.

The Board has established our Code of Conduct (the "Code") that applies to every Director, Officer and employee, with no exception. All receive annual training and are required to complete a declaration of compliance with the Code.

Our Code promotes speaking up and outlines our commitment against intimidation and retaliation. Our Code also requires employees and Board members to report all known and suspected breaches. Our Ethics Hotline empowers our employees to play an active role in protecting the organization. They can use the Ethics Hotline to report allegations of misconduct anonymously or if they feel their concerns have not been resolved using other reporting methods.

Communications that accompanied the Code in 2023 continued to reinforce our expectations of behaviours in the workplace; emphasizing the importance of speaking up, fostering a workplace that is free of harassment of any kind and promoting diversity, equity and inclusion.

The Governance, Investment & Sustainability Committee of the Board is responsible for reviewing the effectiveness of the Code, monitoring compliance and reporting the results of its review to the Board annually. On a quarterly basis, the Chief Compliance Officer reports on breaches of the Code and reviews our controls and compliance with the Governance, Investment and Conduct Review Committee. No waivers of the Code for directors or executive officers have been granted.

The most recent copy of the Code is available on our website (www.sunlife.com). The Code has been filed with the Canadian Securities Administrators ("CSA") in Canada on SEDAR (www.sedarplus.ca) and with the SEC in the United States on EDGAR (www.sec.gov/EDGAR).

Pre-Approval Policies and Procedures
The Audit Committee of SLF Inc. and Sun Life Assurance have adopted a policy restricting the use of the external auditor (the "Policy"). The objective of the Policy is to ensure that the independence of the external auditor is not compromised by certain engagements. The Policy is based on the following principles, which specify that the external auditor cannot:
•function in the role of management of the Company;
•audit its own firm’s work; or
•serve in an advocacy role for the Company.

The Policy requires that any services to be provided by the external auditor be pre-approved by the Audit Committees of SLF Inc. and/or Sun Life Assurance, as applicable, and the audit committee of any affected subsidiary that is itself directly subject to the Sarbanes-Oxley Act of 2002. If a service has not been pre-approved by the Audit Committee, specific approval must be obtained from the committee before an engagement letter can be issued and the related work commenced. The committee has, subject to reporting requirements, pre-approved certain audit, audit-related and other permissible non-audit services that are consistent with maintaining the independence of the external auditor. These pre-approved services are reviewed annually by the committee. The Policy prohibits engaging the external auditor to provide certain services, including:
•bookkeeping or other services related to accounting records or financial statements;
•financial information systems design or implementation services;
•appraisal or valuation services, fairness opinions or contribution in kind reports;
•actuarial services;
•internal audit outsourcing services;
•management functions or human resources services;
•broker or dealer, investment adviser, underwriting, securities or investment banking services;
•legal services and expert services unrelated to an audit;
•any service for which no fee is payable unless a specific result is obtained;
•any non-audit tax services that recommend the Company engage in confidential transactions or aggressive tax position transactions, as defined by the U.S. Public Company Accountability Oversight Board; and
•any other service that governing regulators or professional bodies determine to be impermissible.

Fees paid to SLF Inc.'s external auditors have been approved by the Audit Committee of the Board of SLF Inc. or otherwise in accordance with the Policy. None of the services provided by the Company's external auditors described above were approved pursuant to a waiver of pre-approval provisions under SEC rules (paragraph (c)(7)(i)(C) of Rule 2 - 01 of Regulation S-X).

Interests of Experts

             Annual Information Form 2023

Kevin Morrissey, the Appointed Actuary of SLF Inc., has provided an opinion on the value of policy liabilities and reinsurance recoverables for SLF Inc.'s statements of financial position as at December 31, 2023 and 2022 and the change in the consolidated statement of operations for the years ended December 31, 2023 and 2022. Mr. Morrissey owned beneficially, directly or indirectly, less than 1% of all outstanding securities or other property of SLF Inc. or its affiliates when he prepared that opinion, and after that opinion was prepared, and he does not expect to receive any such securities or other property in excess of that amount in the future.

Regulatory Matters
Sun Life is subject to regulation and supervision by government authorities in the jurisdictions in which it does business.

Canada
Regulation of Insurance Operations
SLF Inc. is incorporated under and governed by the Insurance Act. OSFI administers the Insurance Act and supervises the activities of SLF Inc. SLF Inc. has all the powers and restrictions applicable to life insurance companies governed by the Insurance Act, which permits insurance companies to offer, directly or through subsidiaries or networking arrangements, a broad range of financial services, including:
•Insurance and reinsurance;
•Investment counselling and portfolio management;
•Mutual funds and segregated funds;
•Trust services;
•Banking services;
•Real property brokerage and appraisal; and
•Merchant banking services.

The Insurance Act requires the filing of annual and other reports on the financial condition of insurance companies, provides for periodic examinations of insurance companies' affairs, imposes restrictions on transactions with related parties, and sets out requirements governing certain aspects of insurance companies' businesses.

OSFI supervises SLF Inc. on a consolidated basis to ensure that it has an overview of activities of SLF Inc. and its consolidated subsidiaries. This consolidated supervision includes the ability to review insurance and non-insurance operations of SLF Inc. and subsidiaries and supervisory power to bring about corrective action. OSFI has extensive powers to intervene in the affairs of regulated insurance companies, including the power to request information or documents, to conduct investigations, to require that appropriate actions are taken to address issues identified by OSFI and to levy fines. OSFI may intervene and assume control of an insurance company governed by the Insurance Act if OSFI deems that the amount of the company’s available capital is not sufficient.
Investment Powers
Under the Insurance Act, a life insurance company must maintain a prudent portfolio of investments, subject to certain overall limitations on the amount it may invest in certain classes of investments, such as commercial loans, real estate and stocks. Additional restrictions (and, in some cases, the need for regulatory approvals) limit the type of investments which SLF Inc. can make in excess of 10% of the voting rights or 25% of the equity of any entity, subject to certain available exceptions under the Insurance Act.
Capital and Surplus Requirements
SLF Inc. and Sun Life Assurance, SLF Inc.’s principal operating life insurance subsidiary in Canada, are subject to OSFI’s LICAT capital framework.

The LICAT Guideline uses a risk-based approach for measuring specific life insurer risks and for aggregating the results to calculate the amount of a life insurer’s regulatory required capital to support these risks. LICAT measures the capital adequacy of an insurer using a Total Ratio and a Core Ratio and is one of several indicators used by OSFI to assess an insurer’s financial condition. The Total Ratio is the Qualifying Regulatory Available Capital ("Available Capital") plus Surplus Allowance and Eligible Deposits divided by a Base Solvency Buffer as described below.

The principal elements included in determining Available Capital under LICAT include common shares, contributed surplus, retained earnings, contractual service margin, the participating account, accumulated currency translation account, unrealized gains and losses on available for sale equity and debt securities, qualifying preferred shares, innovative capital instruments and subordinated debt.

The calculation of the Total Ratio takes into consideration other aspects of the balance sheet that are available as loss absorbing capacity, including the Surplus Allowance and Eligible Deposits. The Surplus Allowance includes the risk adjustment
Sun Life Financial Inc. | sunlife.com                                           21

             Annual Information Form 2023
reported in the financial statements for non-financial risks. The Eligible Deposits consist of the excess deposits held for unregistered reinsurers and claims fluctuation reserves.

The Base Solvency Buffer includes five risk components: (1) credit risk, (2) market risk, (3) insurance risk, (4) segregated funds guarantee risk, and (5) operational risk. Credits to the base solvency buffer are available for: (1) qualifying in-force participating and adjustable products, (2) other risk mitigation and risk transfer, and (3) risk diversification.

The LICAT Guideline sets a Supervisory Target Total Ratio of 100% and a minimum Total Ratio of 90%. The supervisory target provides a cushion above the minimum requirements, provides a margin for other risks, and facilitates OSFI’s early intervention process. The supervisory target is not applicable to regulated insurance holding companies and non-operating insurance companies. The Company has established capital targets in excess of the supervisory target set by OSFI.
Restrictions on Dividends and Capital Transactions
The Insurance Act prohibits the declaration or payment of dividends on shares of an insurance company if there are reasonable grounds for believing the company does not have, or the payment of the dividend would cause the company not to have, adequate capital or liquidity, or upon any direction made by the Superintendent. The Insurance Act also requires that an insurance company notify the Superintendent of the declaration of a dividend at least fifteen days before the dividend payment date.

The Insurance Act also prohibits the purchase for cancellation of shares issued by an insurance company or the redemption of redeemable shares or other similar capital transactions, if there are reasonable grounds for believing that the company does not have, or the payment would cause the company not to have, adequate capital or liquidity, or upon any direction made by the Superintendent. Further, any redemption or purchase for cancellation of shares issued by an insurance company or similar capital transactions are prohibited without the prior approval of the Superintendent.
Restrictions on Ownership
The Insurance Act contains restrictions on the purchase or other acquisition, issue, transfer and voting of the shares of an insurance company. Pursuant to these restrictions:
•No person is permitted to acquire any shares of SLF Inc. if the acquisition would cause the person to have a "significant interest" in any class of shares of SLF Inc., without the prior approval of the Minister of Finance of Canada;
•SLF Inc. is not permitted to record any transfer or issue of shares of SLF Inc. if the transfer or issue would cause the person to have a significant interest in SLF Inc., unless prior approval is obtained from the Minister of Finance of Canada; and
•No person who has a significant interest in SLF Inc. may exercise any voting rights attached to the shares held by that person, unless prior approval of the Minister of Finance of Canada is obtained.

A person has a significant interest in a class of shares where the aggregate of any shares of that class beneficially owned by that person, any entity controlled by that person and any person acting jointly or in concert with that person exceeds 10% of all of the outstanding shares of that class of shares.

Under the Insurance Act, the Minister of Finance of Canada may approve only the acquisition of a significant interest of up to 30% of any class of non-voting shares and up to 20% of a class of voting shares, provided that the person acquiring those shares does not have direct or indirect influence over SLF Inc. that, if exercised, would result in that person having control in fact of SLF Inc. In addition, the Insurance Act prohibits life insurance companies, including SLF Inc., from recording a transfer or issuing shares of any class to His Majesty in right of Canada or of a province, an agent of His Majesty, a foreign government or an agent of a foreign government.

SLF Inc. is required to continue to control, but not wholly own, Sun Life Assurance. Any shares of Sun Life Assurance that are not owned by SLF Inc. are required to meet the widely-held criteria (no individual may own more than 10% of any class of shares without prior approval of the Minister of Finance of Canada). The 20% limit on voting share ownership and 30% limit on non-voting share ownership apply to the direct and indirect cumulative ownership of Sun Life Assurance, with the effect that no single investor will be able to use the holding company structure to exceed those ownership restrictions.
Appointed Actuary
In accordance with the Insurance Act, SLF Inc.'s Board has appointed a Fellow of the Canadian Institute of Actuaries as its "Appointed Actuary". The Appointed Actuary must provide an opinion on:
•The value of the Company's consolidated policy liabilities as at the end of each fiscal period in accordance with accepted actuarial practice, including the selection of appropriate assumptions and methods;
•Whether the amount of policy liabilities makes appropriate provisions for all obligations to policyholders; and
•Whether the valuation of liabilities is fairly presented in the consolidated financial statements.

Sun Life Financial Inc. | sunlife.com                                           22

             Annual Information Form 2023
Regulations require that the Appointed Actuary meet with the Board or a delegated Committee of the Board at least once in each financial year to report, in accordance with accepted actuarial practice, on the Company's financial position and its expected future financial condition. The Appointed Actuary must report to the Chief Executive Officer and the Chief Financial Officer of SLF Inc. any matters that, in the Appointed Actuary's opinion, could have material adverse effects on the financial condition of SLF Inc.
Prescribed Supervisory Information
The Supervisory Information (Insurance Companies) Regulations made under the Insurance Act prohibit regulated insurance companies, such as SLF Inc. and Sun Life Assurance, from disclosing, directly or indirectly, "prescribed supervisory information", as defined in those Regulations. Prescribed supervisory information includes assessments, recommendations, ratings and reports concerning a company made by or at the request of the Superintendent, orders of the Superintendent with respect to capital and liquidity, certain regulatory actions taken with respect to a company, prudential agreements between a company and the Superintendent, and directions of the Superintendent that a company cease or refrain from committing, or remedy, unsafe or unsound practices in conducting its business.
Provincial/Territorial Insurance Regulation
In Canada, life insurance is also subject to provincial/territorial regulation and supervision in each province and territory in Canada. Provincial/territorial insurance regulation is primarily concerned with market conduct matters, the rights and obligations under insurance contracts, and the licensing and oversight of insurance intermediaries. In addition to those regulations, guidelines adopted by the Canadian Life and Health Insurance Association ("CLHIA") govern several aspects of our business in Canada.

SLF Inc. is licensed as an insurance company in Canada under the Insurance Act and is the holding company for the Sun Life group of companies. SLF Inc. is not licensed to carry on life insurance business in any province or territory in Canada.

Sun Life Assurance and Sun Life Insurance (Canada) Limited are licensed to carry on life insurance and accident and sickness insurance business in each province and territory in Canada.
Regulation of Securities Operations
Several of SLF Inc.'s subsidiaries in Canada are registered with various Canadian Securities Administrators as dealers, advisors or managers under one or more of the following categories of registration: mutual fund dealer, investment dealer, investment fund manager, commodity trading manager, portfolio manager and exempt market dealer. These entities, their registered employees and their products and/or services are regulated in Canada under provincial and territorial securities laws which are administered and enforced by the various Canadian Securities Administrators, and certain entities are also subject to the rules of the applicable self-regulatory organization, including as of January 1, 2023, the Canadian Investment Regulatory Organization ("CIRO"), the self-regulatory organization resulting from the amalgamation of the Mutual Fund Dealers Association of Canada and the Investment Industry Regulatory Organization of Canada. These entities may be subject to examinations or proceedings by the various Canadian Securities Administrators and self-regulatory organizations. These examinations or proceedings could subject our registered subsidiaries to a range of regulatory sanctions, including censure, limitations on the registrant's activities, and termination of registration, and could subject these entities to a cessation of sales or the rescission of a sale of securities.
Client Protection for Financial Institution Failure
Sun Life Assurance’s Canadian policyholders are provided protection from an insolvency through Assuris, a not for profit organization that is funded by its member insurance companies. Every life insurance company authorized to sell insurance policies in Canada is required, by the federal, provincial and territorial regulators, to become a member of Assuris. Assuris provides separate protection for individual, group, registered and non-registered, life insurance policies and annuity policies.

The CIRO Canadian Investor Protection Fund ("CIPF") provides Clients with protection, within defined limits, in the event of the insolvency of a CIRO member. The CIPF is funded by its members, including Sun Life Financial Investment Services (Canada) Inc. and Sun Life Canada Securities Inc.

The Canada Deposit Insurance Corporation ("CDIC") is a federal crown corporation created to protect deposits made with member financial institutions in case of their failure. CDIC member institutions, including Sun Life Financial Trust Inc., fund deposit insurance through premiums paid on the insured deposits that they hold.
Other Regulatory Matters
Privacy of Client Information and Anti-Spam Legislation
Canadian federal, and some provincial, laws and regulations require organizations, including financial institutions, to protect the security and confidentiality of Client information. This includes financial institutions notifying Clients about their policies and practices relating to their collection, use and disclosure of Client information, including protection of that information. Requirements also include an obligation to notify individuals and report to privacy regulators when there is a real risk of significant harm to affected individuals resulting from a breach of security safeguards. In 2021, the Quebec government passed legislation that will significantly alter privacy legislation by introducing new rights for individuals, additional
Sun Life Financial Inc. | sunlife.com                                           23

             Annual Information Form 2023
obligations for organizations and expansive enforcement powers and financial penalties for non-compliance. The Quebec privacy legislation has been coming into force over a three year period with the final changes coming into force in September 2024. Canadian anti-spam legislation imposes certain restrictions and formalities on the delivery of commercial electronic messages to existing and prospective Clients. This includes obtaining consent from recipients and providing the ability to unsubscribe from subsequent messages.
Anti-Money Laundering Legislation
The Proceeds of Crime (Money Laundering) and Terrorist Financing Act, Canada, contains measures to assist in detecting, deterring, and facilitating the investigation of money laundering and terrorist financing offences. This legislation and the associated regulations impose reporting, recordkeeping and "know your Client" obligations on SLF Inc. and certain of its subsidiaries.
Technology and Cybersecurity
In July 2022, OSFI issued Guideline B-13 on Technology and Cyber Risk Management which came into effect on January 1, 2024. The Guideline applies to all federally regulated financial institutions, including insurance companies, with the stated objective of helping institutions develop greater resilience to technology and cyber risks.

United States
In the U.S., SLF Inc. does not carry on business and is not regulated as an insurance company. Sun Life Assurance and several indirect U.S. subsidiaries of SLF Inc. carry on business and are regulated as insurance companies in the United States. Michigan is Sun Life Assurance's "state of entry" and is treated as the state of domicile for Sun Life Assurance's U.S. branch (the "U.S. Branch"). The U.S. Branch is licensed to transact business in every state in the United States except New York, plus in the District of Columbia, Puerto Rico, and the U.S. Virgin Islands. SLF Inc.'s U.S. life and health insurance subsidiaries are, collectively, licensed to transact business in all states, the District of Columbia, and Puerto Rico.

Certain U.S. subsidiaries of SLF Inc. (including DentaQuest and its subsidiaries) offer products and services to federal and state health programs that are governed by federal law and subject to regulation by the Centers for Medicare and Medicaid Services ("CMS"). The state health programs are also governed by state health care laws administered by state Medicaid agencies.

In addition, some of SLF Inc.'s U.S. subsidiaries (including MFS and its subsidiaries; Sun Life Capital Management (U.S.) LLC; BGO, Crescent, AAM and certain of their respective subsidiaries; and some subsidiaries of InfraRed) and various contracts, policies and funds issued, offered or managed by them are subject to regulation under federal securities laws administered by the SEC and under certain state securities laws.
Regulation of Insurance Operations - State Level
In the United States, all states, the District of Columbia, and the U.S. territories and possessions have insurance laws that apply to companies licensed to carry on an insurance business in the jurisdiction. The primary regulator of an insurance company, however, is the state insurance department or equivalent body located in its state of domicile. Most jurisdictions have laws and regulations governing the financial aspects of insurers, including standards of solvency, reserves, reinsurance, and capital adequacy, as well as the business conduct of insurers. In addition, the laws of the various states provide state insurance regulators with broad administrative powers to approve policy forms and related materials and approve rates for certain lines of insurance, grant and revoke licenses to transact business, regulate trade practices, license agents, and require statutory financial statements. The primary purpose of such regulation is the protection of policyholders and consumers, rather than shareholders.

The NAIC is the U.S. standard-setting and regulatory support organization created and governed by the chief insurance regulators from the 50 states, the District of Columbia and five U.S. territories. Through the NAIC, state insurance regulators establish standards and best practices, conduct peer review, and coordinate their regulatory oversight. NAIC members, together with the central resources of the NAIC, form the national system of state-based insurance regulation in the United States.

The U.S. Branch and SLF Inc.'s U.S. life and health insurance subsidiaries are subject to the insurance holding company laws and regulations in the states in which they are domiciled (or deemed to be commercially domiciled). Most states' insurance holding company laws require each insurer that is domiciled therein and that is a member of a holding company system to register with the insurance regulatory authority of that state and, annually, to furnish those authorities with reports that include information concerning capital structure, ownership, financial condition, certain intercompany transactions, enterprise risk management and general business operations. In addition, under most states' holding company laws, transactions within the holding company system to which the domestic insurer is a party must be fair and equitable and the insurer's policyholder surplus following any such transaction must be both reasonable in relation to its outstanding liabilities and adequate for its needs. Most states require prior regulatory approval of the change of control of the domestic insurer or an entity that controls the domestic insurer and prior notice or regulatory approval of certain intercompany transfers of assets or other material affiliate transactions to which a domestic insurer is a party. Generally, under such laws, a state
Sun Life Financial Inc. | sunlife.com                                           24

             Annual Information Form 2023
insurance authority must approve in advance the direct or indirect acquisition of 10% or more of the voting securities of an insurance company domiciled in the state.

SLF Inc.'s U.S. captive insurance companies are subject to the laws and regulations applicable to captive insurers in their states of domicile, as well as the terms of the business plans approved by, and the licensing orders issued by, the companies' domestic regulators. Generally, a captive insurance company is required to seek regulatory approval prior to taking any action that would deviate from the activities described in its approved business plan or specifically permitted by the licensing order issued by its domestic regulator.

The U.S. Branch and SLF Inc.'s U.S. life and health insurance subsidiaries are required to file detailed annual and quarterly financial statements with state insurance regulators in each of the states in which they are licensed, and their business and accounts are subject to examination by such regulators at any time. Regulators have authority to limit or prohibit the ability to issue new policies if, in their judgment, an insurer is not maintaining sufficient surplus or capital or if the further transaction of business would be detrimental to policyholders.

As part of their oversight process, state insurance departments conduct detailed examinations periodically (generally, every three- to five-years) of the financial condition and market conduct of insurance companies domiciled in their states. The latest published examination reports of the U.S. Branch and SLF Inc.'s U.S. life and health insurance companies did not raise any material issues or adjustments. In addition to the periodic examinations, states will on occasion perform targeted market conduct reviews that may cover, among other things, content of disclosures, advertising, sales practices and complaint handling. Examinations are periodically conducted, in cooperation with the departments of other states, under guidelines published by the NAIC.
Restrictions on Dividends
The amount of dividends that an insurance company may pay to its parent without prior regulatory approval is regulated under the U.S. state insurance holding company laws and regulations and under the terms of licensing orders issued by various states.
NAIC IRIS Ratios
The NAIC has developed a set of financial relationships or "tests" known as the Insurance Regulatory Information System ("IRIS") to assist state regulators in monitoring the financial condition of insurance companies and identifying companies that may require special attention or action by insurance regulatory authorities. A second set of confidential ratios, called the Financial Analysis Solvency Tracking System, is also used for monitoring. Insurance companies generally submit data to the NAIC, which in turn analyzes the data using prescribed financial data ratios, each with defined "usual ranges". Having ratios that fall outside the usual range does not necessarily indicate that a company experienced unfavourable results. Generally, if four or more of an insurance company's ratios fall outside the usual ranges, regulators will begin to investigate or monitor the company. Regulators have the authority to impose remedies with various degrees of supervision, ranging from increased monitoring to certain business limitations. For the twelve-month period ended December 31, 2022, the most recent period for which results are available, SLF Inc.'s U.S. life and health insurance subsidiaries were within the usual ranges for most of the IRIS ratios. The U.S. Branch had three ratios outside of the usual ranges. The ratios that were outside the usual ranges did not indicate any adverse solvency issues.
Risk-based Capital Ratio Requirements
All states have risk-based capital ("RBC") ratio requirements for insurance companies. The NAIC RBC system was created to provide a capital adequacy standard that is related to risk, raises a safety net for insurers, is uniform among the states, and provides regulatory authority for timely action. The RBC system requires an insurer to calculate a minimum amount of capital that it must maintain to support the various risks to which it is exposed. A separate factor is used across each major risk category, and may vary by primary insurance type. RBC focuses on the material risks that are common for the particular insurance type. For life and health insurance, RBC considers investment risk, insurance risk, interest rate risk, and other market and business risks, by applying factors to various amounts presented in the company's statutory financial statements. For the year ended December 31, 2023, the RBC ratios for the U.S. Branch and SLF Inc.'s U.S. life and health insurance subsidiaries are expected to exceed the levels under which any remedial or regulatory action would be required.
Statutory Reserves
State insurance laws require life and health insurance companies to analyze the adequacy of their reserves annually. The appointed actuary for the U.S. Branch and SLF Inc.'s other U.S. life and health insurance subsidiaries must submit an opinion that such reserves, when considered in light of the assets held with respect to those reserves, make adequate provision for the associated contractual obligations and related expenses of the U.S. Branch and each of SLF Inc.’s life and health insurance subsidiaries. If such opinion cannot be provided, the affected insurer must set up additional reserves.

Under NAIC rules, life and health insurance companies must maintain an asset valuation reserve ("AVR"), which is a provision for potential asset credit defaults. The size of the AVR depends upon the composition and results of a company’s investment portfolio. These reserves are recorded for purposes of statutory accounting practices; they are not recorded under the provisions of IFRS and therefore have no impact on SLF Inc.'s reported results of operations or financial position. The AVR affects the determination of statutory surplus, and changes in such reserves may affect the ability of SLF Inc.'s U.S. life and
Sun Life Financial Inc. | sunlife.com                                           25

             Annual Information Form 2023
health insurance subsidiaries to pay dividends or other distributions to their respective parents and also may affect the amounts required to be maintained in trust by the U.S. Branch (see discussion below under Minimum Statutory Surplus and Capital).
Minimum Statutory Surplus and Capital
The U.S. Branch and SLF Inc.'s U.S. life and health insurance subsidiaries are required to have minimum statutory surplus and capital of various amounts, depending on the states in which they are licensed and the types of business that they transact.

The U.S. Branch is required to maintain a certain amount of assets in trust with a financial institution acceptable to the Director of Michigan's Department of Insurance and Financial Services (the "Michigan Director") in an amount at all times at least equal to the sum of the U.S. Branch's reserves and other liabilities, the minimum required capital and surplus, and any additional amounts considered necessary by the Michigan Director to cover the U.S. Branch's liabilities. Generally, these assets are available only to meet the obligations of Sun Life Assurance to its U.S. policyholders, claimants and other U.S. Branch creditors. Amendments to the trust agreement must be approved by the Michigan Director. As at December 31, 2023, the U.S. Branch had assets in trust in excess of Michigan’s requirements.
Investments of Insurance Companies
The U.S. Branch and SLF Inc.'s other U.S. life and health insurance subsidiaries are subject to state laws and regulations that require diversification of their investment portfolios and limit the amount of investments in certain investment categories such as below-investment-grade fixed income securities, equity real estate, foreign investments and equity investments. Failure to comply with these laws and regulations would cause investments exceeding regulatory limits to be treated as non-admitted assets for purposes of measuring surplus and, in some instances, would require divestiture of such non-qualifying investments.
State Guaranty Association Assessments
All states, the District of Columbia and Puerto Rico require insurers to participate in the local insurance guaranty association. The association may levy assessments for policyholder losses incurred by impaired or insolvent insurers. Generally, assessments up to certain prescribed limits are based upon the proportionate share of premiums written by member insurers in the lines of business in which the impaired or insolvent insurer is engaged. A large part of the assessments paid by SLF Inc.'s U.S. insurance subsidiaries pursuant to these laws may be used as credits for a portion of its U.S. premium taxes.
Regulation of Insurance Operations - Federal Level
Although the U.S. federal government does not directly regulate the insurance business, federal legislation and administrative policies in several areas apply to the conduct of the insurance business, including age and sex discrimination, investment company regulation, financial services regulation, health care regulation, foreign corrupt practices regulation and federal taxation. For example, the U.S. Congress has, from time to time, considered legislation related to limitations on antitrust immunity and the alteration of the federal income tax structure.

DentaQuest and certain other U.S. subsidiaries of SLF Inc. administer dental and vision benefits for federal and state health programs that are governed by federal law, including Medicaid and Children’s Health Insurance programs, Medicare Advantage plans, and offerings on federal and state exchanges under the Patient Protection and Affordable Care Act. CMS is the U.S. federal agency that regulates each of these programs. Each U.S. state administers its own Medicaid program and has its own laws and regulations in place. The exchange in each state is operated by CMS, a state agency, or a partnership between the two.
Regulation of Securities Operations
The investment management activities of SLF Inc.'s U.S. subsidiaries are subject to federal and state laws and regulations in the jurisdictions where they conduct business. MFS and certain of SLF Inc.'s other U.S. subsidiaries are registered as investment advisers under the Investment Advisers Act of 1940, as amended (the "Advisers Act"), which imposes various obligations on registered investment advisers, including fiduciary duties, and disclosure, operational, recordkeeping and reporting requirements.

Several of SLF Inc.'s U.S. subsidiaries issue or have issued products that are registered with the SEC as investment companies under the Investment Company Act of 1940, as amended (the "1940 Act") and which issue securities that are registered under the Securities Act of 1933, as amended (the "1933 Act"). Certain of SLF Inc.'s U.S. subsidiaries provide investment management services to affiliated funds, which similarly are registered as investment companies under the 1940 Act and which issue securities that are registered under the 1933 Act. The 1940 Act and the 1933 Act impose various obligations on registered investment companies and with respect to the securities that they issue, including disclosure, operational, recordkeeping and reporting requirements and, in the case of the 1940 Act, prohibitions or restrictions on certain transactions with affiliates.

Registered investment companies and investment advisers are regulated by and subject to examination by the SEC. The SEC is authorized to institute proceedings and impose sanctions for violations of the U.S. federal securities laws. Failure to comply with applicable securities laws could subject SLF Inc.'s investment companies and investment adviser subsidiaries to a range
Sun Life Financial Inc. | sunlife.com                                           26

             Annual Information Form 2023
of regulatory sanctions, including censure, limitations on the registrant's activities, and termination of registration, and could subject its registered investment companies to a cessation of sales or rescission of securities sold.

To the extent that any products are deemed to be securities under U.S. federal or state securities laws, they are qualified for sale as needed in certain states in the United States and the District of Columbia. Marketing and sales of securities products are subject to the Securities Exchange Act of 1934, as amended (the "1934 Act"), and regulations promulgated by the Financial Industry Regulatory Authority ("FINRA").

Certain of SLF Inc.'s U.S. subsidiaries are registered as broker-dealers under the 1934 Act and are subject, for example, to the SEC's net capital rules, and are members of, and subject to regulation by FINRA. Certain other U.S. subsidiaries of SLF Inc. are registered as transfer agents under the 1934 Act.

MFS, BGO, Crescent and InfraRed also conduct business in the EU that is also subject to securities laws and regulations. The revised Markets in Financial Instruments Directive and Regulation ("MiFID II") became effective on January 3, 2018 and applies across the EU and member states of the European Economic Area ("EEA"). Some of the main changes introduced under MiFID II include applying enhanced disclosure requirements, enhancing conduct of business and governance requirements, broadening the scope of pre and post trade transparency, increasing transaction reporting requirements, transforming the relationship between Client commissions and research, and further regulation of trading venues. Implementation of MiFID II has had a significant impact on both the structure and operation of EU financial markets. In response to MiFID II, MFS is paying for all external investment research for all Clients (including non-European Clients).
Other U.S. Regulatory Matters
U.S. Taxation
The Inflation Reduction Act ("IRA") was enacted on August 16, 2022 and includes provisions enacting a 15% corporate alternative minimum tax ("CAMT") that applies to certain corporations for tax years beginning after December 31, 2022. The Treasury/IRS is expected to continue issuing substantial guidance related to these legislative changes in the coming months. The CAMT and other provisions of the IRA are not expected to have a material impact on our tax expense in the U.S.
The Dodd-Frank Act
The Wall Street Reform and Consumer Protection Act ("Dodd-Frank Act"), which was signed into law in July 2010, enacted numerous legal and regulatory changes for the financial services industry, which have been gradually implemented over the ensuing years.

The Dodd-Frank Act mandated the U.S. federal regulation of the over-the-counter ("OTC") derivatives market and granted new joint regulatory authority to the SEC and the U.S. Commodity Futures Trading Commission ("CFTC") over OTC derivatives. The SEC and CFTC have promulgated rules to implement the Dodd-Frank Act's requirements, and certain of Sun Life's derivatives operations have become subject to, among other things, new recordkeeping, reporting and documentation requirements. In addition, certain non-cleared derivatives entered into as part of Sun Life’s derivatives operations are subject to two-way variation and, with certain of Sun Life’s derivatives counterparties, initial margin requirements. These margining requirements may increase the cost, and reduce the availability of, non-cleared derivatives. Collectively, the Dodd-Frank Act requirements, and the requirements of similar legislation that has been promulgated by Canadian and European regulators, have increased the direct and indirect costs of the Company's hedging and related activities and will likely increase them further in the future.
Interest Rate Benchmark Reform
Interbank offered rates ("IBORs") measure the average cost that banks pay to borrow from each other on an unsecured short-term basis. They have historically been used as a benchmark or reference rate for various types of financial products and contracts, including Sun Life’s derivatives, loans and floating rate securities investments (collectively, the "Investments") that are IBOR-based.

On March 5, 2021, the ICE Benchmark Administration (the entity that is responsible for calculating LIBOR) announced its intention to cease the publication of (a) the one-week and two-month US dollar LIBOR settings, as well as all GBP, EUR, CHF and JPY LIBOR settings, immediately following the LIBOR publication on December 31, 2021, and (b) the remaining US dollar LIBOR settings, immediately following the LIBOR publication on June 30, 2023. All LIBOR settings were either discontinued or declared non-representative on or before June 30, 2023.

The Alternative Reference Rates Committee of the Federal Reserve Board identified the Secured Overnight Financing Rate ("SOFR") as the replacement rate for US dollar LIBOR, and published industry-specific fallback language for use by market participants for contract remediation in order to address the transition from US dollar LIBOR to SOFR.

In Canada, on June 22, 2021, OSFI, consistent with international efforts, outlined its expectations of federally regulated financial institutions ("FRFIs") as they transition away from LIBOR. Also, on May 16, 2022, Refinitiv Benchmark Services (UK) Limited announced that it will permanently cease the publication of all three tenors of the Canadian Dollar Offered Rate ("CDOR") after June 28, 2024. Concurrently, OSFI published its expectation that FRFIs transition all new derivatives and
Sun Life Financial Inc. | sunlife.com                                           27

             Annual Information Form 2023
securities to an alternative reference rate by June 30, 2023, with no new CDOR exposure being booked after that date (with limited exceptions for risk management requirements), and that loan agreements referencing CDOR be transitioned by June 28, 2024. FRFIs are also expected to prioritize system and model updates to accommodate the transition from CDOR prior to such date.

The Canadian Alternative Reference Rate working group (“CARR”), established by the Canadian Fixed-Income Forum committee of the Bank of Canada (“CFIF”), has facilitated the adoption of the Canadian Overnight Repo Rate Average (“CORRA”) as the replacement rate for CDOR, and published a two-stage transition plan as well as industry specific fallback language for use by market participants for contract remediation, in order to address the transition from CDOR to CORRA.

Also, with the cessation of CDOR’s publication after June 28, 2024, the Bankers’ Acceptance (“BA”) lending model will be discontinued, and BA issuance is expected to cease. To facilitate the Canadian loan markets’ move away from CDOR and BAs, on July 27, 2023, the CARR implemented a milestone in its transition plan whereby no new CDOR or BA-related contract should be entered into after November 1, 2023. CFIF has formed a BA-related working group to facilitate a smooth transition away from BAs to assess potential options to replace them.

It is difficult to fully predict the effects of the above-mentioned benchmark reform. Accordingly, Sun Life continues to implement a comprehensive enterprise-wide program to ensure an effective and smooth transition to appropriate alternative reference rates.
Cybersecurity and Privacy of Client Information
U.S. regulators at the federal and state level are increasing their focus on privacy and cybersecurity. In particular, the New York Department of Financial Services has amended its existing regulations designed to enhance cybersecurity controls of financial institutions, and the Department includes cybersecurity programs within the scope of examination. The NAIC has developed a model cybersecurity regulation based on New York's rule and multiple states have adopted similar measures. These regulations require licensees, including certain of SLF Inc.’s U.S. insurance subsidiaries, to implement risk-based information security programs; establish detailed procedures for investigating cybersecurity events, assessing risk, and overseeing third-party service providers; and comply with increased regulatory reporting requirements.

In addition, U.S. federal and state laws require financial institutions, including insurers, investment companies and investment dealers, to protect the security and confidentiality of Client information and to notify Clients about the institution’s policies and practices relating to its collection, use and disclosure of Client information. The State of California has enacted legislation and regulations designed to enhance consumer privacy rights, and other states have enacted or are considering similar consumer focused privacy laws. These laws and regulations will significantly change data privacy requirements in the U.S., impose greater penalties for non-compliance, and provide for consumer rights to access, delete and correct their personal information and, in some states, provide a private right of action.

These laws and regulations will also increase the costs and compliance obligations associated with the Company’s information security and administration activities.
The USA PATRIOT Act of 2001
The USA PATRIOT Act of 2001 (the "PATRIOT Act") seeks to promote cooperation among financial institutions, regulators and law enforcement agencies in identifying parties that may be involved in terrorism, money laundering or other illegal activities. Regulations applicable to the insurance industry require insurance companies issuing "covered products" to implement anti-money laundering programs and file suspicious activity reports with the U.S. Treasury Department. SLF Inc.'s U.S. subsidiaries that issue covered products and its U.S. broker-dealer subsidiaries have implemented anti-money laundering control programs to comply with the PATRIOT Act regulations and with the Office of Foreign Assets Control requirements with respect to anti-terrorist financing.
Paid Family and Medical Leave
A growing number of states have passed or are considering mandated paid family and medical leave ("PFML") programs. These programs generally provide partial income protection for an employee who is unable to work on account of his or her own serious health condition or for various family care reasons. There are a number of PFML proposals at the federal level as well. While PFML programs overlap with short term disability coverage and, as a result, could have a negative impact on the short term disability marketplace in which the U.S. Branch and SLF Inc.’s U.S. life and health subsidiaries operate, these programs also offer an opportunity for insurers to build new products to serve an emerging market.

Asia
Sun Life carries on business through subsidiaries, joint ventures or associates in the Philippines, Hong Kong, Indonesia, Vietnam, India, China, Malaysia and Singapore. The operations of our subsidiaries, joint ventures and associates in Asia are subject to the local regulatory and supervisory schemes in the jurisdictions in which they operate, which varies from country to country, but the regulators typically grant (or revoke) licenses to operate and control the ability of a company to operate an insurance business in that country.

PT Sun Life Financial Indonesia is licensed to carry on life insurance business in Indonesia and can distribute life insurance products in Indonesia. PT Sun Life Financial Indonesia can additionally manufacture and distribute sharia products in Indonesia through its sharia business.

The Indonesian Financial Services Authorities (Otoritas Jasa Keuangan) ("OJK") is the regulator responsible for supervising and regulating the financial service industries in Indonesia, including the insurance industry. The Indonesia Life Insurance Association ("AAJI") continues to act as a conduit between life insurers and the Ministry of Finance and the OJK in terms of the development of new regulations and guidelines in relation to the life insurance sector. Life insurance sales forces (i.e. agents) are licensed by the AAJI. The Indonesia Sharia Insurance Association acts in the similar capacity as AAJI in relation to the sharia insurance business. The implementation of anti-money laundering controls in the insurance industry is also monitored by the Indonesian Financial Transaction Reports and Analysis Center, in addition to it being under the general supervision of the OJK.

Life insurance companies in Indonesia are required to maintain a minimum solvency ratio of 120% of the minimum required capital and must have minimum shareholder equity of 100 billion Indonesian Rupiah.

In July 2023, OJK issued Regulation No. 11 of 2023 on Spin-off of Sharia Units of Insurance Companies and Reinsurance Companies (“OJK Regulation 11”), which outlined the extension of a deadline and requirements for the spin-off of the sharia business units of insurance companies. OJK Regulation 11 extends the deadline for insurers to spin-off sharia business units from October 17, 2024 to December 31, 2026, and introduced certain new requirements including a requirement to submit amendments to sharia spin-off plans to the OJK by December 31, 2023. The amended sharia spin-off plan of PT Sun Life Financial Indonesia was submitted to the OJK on December 15, 2023 for approval.

Vietnam
In Vietnam, we offer a diverse range of insurance, savings, investment and pension products through our wholly owned subsidiary Sun Life Vietnam Insurance Company Limited. There are no foreign ownership restrictions applicable to Sun Life Vietnam, however, a transfer of 10% or more of the charter capital of any life insurer must be approved by the Ministry of Finance of Vietnam ("MOF").

In June 2022, the Vietnam National Assembly adopted a new Law on Insurance Business (the "Law on Insurance Business 2022") which took effect from January 1, 2023, with the exception of some requirements that have a transition period. In July 2023, the Government of Vietnam issued a new decree on the implementation of the Law on Insurance Business 2022 (“Decree No. 46”), which took effect from July 1, 2023 with a number of provisions taking retroactive effect from January 1, 2023.

Insurance operations in Vietnam are mainly regulated by the MOF, which sets the standards on all insurance business matters, including product approvals, limits on commission rates payable on insurance products, actuarial liability valuation, and solvency requirements. Life insurers have responsibility for minimum legal capital of Vietnamese Dong ("VND") 600 billion and that a security deposit equal to 2% of the legal capital be maintained at a commercial bank in Vietnam. Life insurers that sell pension products or unit-linked products are required to have a minimum legal capital of VND 800 billion. Life insurers that sell pension and unit-linked products are required to have a minimum legal capital of VND 1,000 billion. The equity of the owner of a life insurer must not be lower than the required minimum legal capital applicable to that insurer. Current minimum legal capital requirements of life insurers that sell pension products or unit-linked products will continue to apply to life insurers licensed before January 1, 2023 (including Sun Life Vietnam) until the end of 2027. Beginning January 2028, life insurers in Vietnam will be required to follow increased minimum legal capital requirements set out in Decree No. 46, including minimum requirements of VND 750 billion for life insurers generally, VND 1,000 billion for life insurers selling pension or unit-linked products and VND 1,300 billion for life insurers selling pension and unit-linked products.

The required solvency margin is VND 300 billion over the minimum solvency margin for insurers selling pension products and VND 200 billion over the minimum solvency margin for insurers selling unit-linked and universal life products. The MOF also requires life insurers to maintain: (a) minimum reserves; (b) for unit-linked policies, a minimum solvency margin of 1.5% insurance reserves plus 0.3% of the sums at risk; (c) for universal life products and pension products, a minimum solvency margin of 4% of insurance reserves plus 0.3% of the sums at risk; and (d) for other life insurance policies and health policies, a minimum solvency margin of 4% of insurance reserves plus either (i) 0.1% of sums at risk for policies with a term of five years or less, or (ii) 0.3% of the sums at risk for policies with a term over five years. Life insurers must also establish a reserve fund to ensure their solvency. These minimum solvency margin requirements will continue to apply until the end of 2027, and thereafter life insurers will be required to maintain a RBC ratio (as further described below). Life insurers are to deduct 5% of annual profit after-tax to set up a compulsory reserve fund, the maximum of which is equal to 10% of the charter capital.

Sun Life Vietnam’s products are generally distributed through a career agency sales force, including individual agency, corporate agency and bank partner, for individual Clients and through a corporate agency for corporate Clients. Sun Life Vietnam has an option to contract with eligible insurance auxiliary service providers to support Sun Life Vietnam in selling Sun Life Vietnam's products to Clients. The insurance auxiliary services include insurance consultation, insurance risk assessment, insurance calculation, insurance loss assessment and insurance claim assistance.

Notably, the Law on Insurance Business 2022 allows 100% foreign ownership for onshore insurers and re-insurers. The Law on Insurance Business 2022 also provides for a clearer regime for market participants (including Sun Life Vietnam) to provide insurance services and products via online platforms, and introduces regulations on RBC in order to apply a RBC management model in the Vietnamese insurance market. Accordingly, an insurer’s solvency will be conditional on, among other things, maintaining a capital adequacy ratio based on the actual capital and the risk-based capital of the insurer. The risk-based capital will be determined based on the size and quantification of the impacts of various groups of risks on the business activities of the insurer including: (i) insurance risks, (ii) market risks, (iii) operational risks, (iv) other risks that have not been taken into account. The RBC regime is under development by the MOF with international and market consultation to ensure its full implementation by January 1, 2028.

On November 2, 2023, the MOF issued the New Circular No. 67/2023/TT-BTC (“Circular No. 67”), which took immediate effect and details a number of provisions of the Law on Insurance Business 2022 and Decree No. 46. Circular No. 67 provides new guidelines for the insurance sector, including requirements related to: (i) payment to distribution channels being tied to quality and persistency targets; (ii) a cap on the override compensation to the distribution channels from 2026; (iii) restrictions on selling investment-linked products to loan clients of the corporate agent; (iv) audio recording insurance consultations; and (v) having acknowledgement of policyholders in illustration materials, and for the sale of investment-linked products.

products through a multi-channel distribution network, including an agency sales force, bancassurance distribution, brokers and worksite marketing.

Insurance operations in India are regulated by the Insurance Regulatory & Development Authority of India ("IRDAI"), whose duties include issuing certificates of registration to insurance companies, protecting the interests of policyholders, and regulating, promoting and ensuring the orderly growth of the insurance industry. In recent years, a number of regulatory changes have been introduced, affecting matters that include product design and structure including commissions, distribution, investments, expense management, risk management, corporate governance, insurer's registration, remuneration of non-executive directors and key management persons and grievance handling.

Life insurance companies in India are expected to maintain a Minimum Solvency Ratio (Total Assets Available for Solvency / Required Solvency Margin) of 150% at all times, where the Required Solvency Margin is an amount calculated by applying specified factors to reserves and amounts-at-risk. Life insurance companies are required to maintain their Available Solvency Margin at a level which is not less than the greater of fifty per cent of the amount of minimum required capital and one hundred percent of Required Solvency Margin. The Minimum Paid-up Capital for life insurers is INR 1 billion.


The foreign investment limit in the insurance sector in India is 74% of the equity share capital in an Indian insurance company subject to the insurance company meeting the condition that a majority of its directors, a majority of its Key Management Persons, and at least one among the Chairperson of its Board, its Managing Director and its CEO must be Resident Indian Citizens. In addition, prior approval is required from the IRDAI for any sale of shares over 1% of the total equity share capital and any purchase which will result in a shareholding being increased beyond 5% of the equity share capital. Increases in foreign investment in an Indian insurance company must comply with the pricing guidelines specified by the Reserve Bank of India.

China
Sun Life Everbright Life Insurance Company Limited is a domestically-invested life insurance company in China, in which we have a 24.99% ownership stake. It operates a multi-distribution model that combines a direct career agency, brokerage, group insurance and bancassurance alliances to sell individual life and health insurance and savings products.

Sun Life Everbright Life Insurance Company Limited has a 99% ownership stake in Sun Life Everbright Asset Management Co., Ltd, which carries on business in China as an insurance asset management company.

The insurance industry in China is regulated by the newly created National Administration for Financial Regulation (“NAFR”), which replaces the former China Banking and Insurance Regulatory Commission (“CBIRC”). The NAFR supervises the financial industry (with the exception of the securities sector) and is responsible for protecting the rights and interests of financial consumers, strengthening risk management and investigating and enforcing laws and regulations. The NAFR has taken over certain functions of the People’s Bank of China and the China Securities Regulatory Commission, including the routine supervision of financial companies and the protection of financial consumers and investors.

Currently, insurance companies established in China (including life insurance companies) are allowed to use their insurance funds (including their capital funds, reserve funds, undistributed profits, various reserves and other funds, whether dominated in RMB or a foreign currency) to invest in the following assets (subject to the satisfaction of conditions prescribed for each form of investment): bank deposits, various negotiable securities (such as government bonds, corporate bonds, financial bonds, stocks, units of securities investment funds), publicly offered infrastructure securities investment funds, security lending business, real estate, equity interest, financial derivatives such as forwards, options and interest rate swaps (provided that investment in any financial derivatives must not be speculative but be only intended for risk hedging and investment in offshore financial derivatives is subject to additional requirements of the regulator), products of insurance asset management companies (including debt investment plans, equity investment plans, portfolio products and other products approved by the
Sun Life Financial Inc. | sunlife.com                                           31

             Annual Information Form 2023
regulator), certain qualified financial products (including wealth management products, trust plans of assembled funds, debt-to-equity swap plans, credit asset backed securities, single asset management plans and other products approved by the regulator) of commercial banks, wealth management companies, trust companies, financial asset investment companies, securities companies, securities asset management companies, securities investment fund management companies and other financial institutions and other investment channels as approved by the State Council.

The minimum paid-up capital of an insurance company is RMB200 million (in cash only) and there are additional capital requirements when additional branches are established.

Insurance asset management companies are also regulated by the NAFR and may conduct the following businesses, among others: (i) managing insurance funds entrusted to them by their clients (including but not limited to their shareholders and the insurance companies controlled by their shareholders) and various assets generated therefrom; (ii) managing other funds (including basic endowment insurance funds, social security funds, enterprise annuity funds, occupational annuity funds and other funds of domestic and foreign qualified investors) and various assets generated therefrom; (iii) managing and utilizing their own funds in RMB or foreign currencies; and (iv) maintaining an asset-backed security business and offering insurance asset management products.

The management and utilization of insurance funds by insurance asset management companies is subject to requirements and limitations that are similar to those applicable to insurance companies. Currently, insurance asset management companies established in China are allowed to use the entrusted insurance funds to invest in the following assets: bank deposits, government bonds, financial bonds, stocks, security investment funds, financial products (including wealth management products, trust plans of assembled funds, debt-to-equity swap plans, credit asset backed securities and other products approved by the regulator), indirect equity investments and real estate asset investments (other than real estate investments through equity holdings or direct ownership of real estate assets) and other investment channels as approved by the State Council. Independent custodians are designated for funds managed by insurance asset management companies and those custodians must be commercial banks or other financial institutions that satisfy regulatory requirements. The registered capital of an insurance asset management company must not be less than RMB100 million or the equivalent amount in a freely convertible foreign currency.

Insurance companies may, either by themselves or by entrusting qualified investment managers, use their insurance funds to make investments, and such "qualified investment managers" include insurance asset management companies and their subsidiaries. Insurance asset management companies are allowed to manage and utilize not only entrusted insurance funds, but also other entrusted funds of non-insurance clients.

Insurance asset management companies are also allowed to carry out insurance asset management product business in accordance with the regulator's rules and should complete the product issuance, registration, custody, transaction, settlement, information disclosure and other processes via an asset registration and transaction platform as approved by the regulator. The regulator is responsible for dynamically supervising the full process of the operation and management of such products and identifying the ultimate investors (beneficiaries) and the underlying assets.

Effective January 1, 2020, the former CBIRC lifted the previous 51% cap on foreign ownership in life insurance companies established in China, which means that a foreign investor is now permitted to wholly own a life insurance company in China. In October 2019, the former CBIRC also implemented an amendment to the Administrative Regulations on Foreign-Invested Insurance Companies, which relaxes market access by removing the requirement that a foreign insurance company must have engaged in insurance business for more than 30 years and have maintained a representative office in China for at least two years before it can establish a foreign invested insurance company in China, and allows foreign insurance groups to invest in and establish an insurance company and other overseas financial institutions to make investments in insurance companies.

Effective September 1, 2022, the Regulations on the Management of Insurance Asset Management Companies no longer include restrictions on the shareholding ratio of foreign investors in insurance asset management companies.
Hong Kong
Our operations in the Hong Kong Special Administrative Region offer a full range of products to address insurance and savings needs. We offer individual life and health insurance, mandatory provident funds (the government-legislated pension system) and pension administration to individuals and businesses through a career sales agency force and independent financial advisors.
Sun Life Hong Kong Limited ("SLHK") is authorized by the Hong Kong Insurance Authority ("IA") under the Insurance Ordinance to carry on certain classes of long-term business in or from Hong Kong. On June 26, 2017, the IA took over from the previous governmental regulator, the Office of the Commissioner of Insurance, the functions of overseeing the authorization and regulation of insurance companies in Hong Kong. On September 23, 2019, the IA took over the regulation of insurance intermediaries from the then existing self-regulatory organizations through a new statutory licensing and intermediary supervision regime. The offer of our investment linked insurance products, pooled retirement funds, approved pool investment funds, mandatory provident fund schemes and occupational retirement schemes are also regulated by one or more of the financial services regulators, including the IA, the Hong Kong Securities and Futures Commission and/or the
Sun Life Financial Inc. | sunlife.com                                           32

             Annual Information Form 2023
Mandatory Provident Fund Schemes Authority. Our trustees and intermediaries who administer and distribute these products, funds and schemes are also supervised and regulated by one or more of the above regulators.
In Hong Kong, long-term insurance companies are required to maintain at all times a required solvency margin. Under the current law, the required solvency margin is the higher of $2 million Hong Kong dollars ("HKD") or the aggregate of two components: a percentage of the mathematical reserves and a percentage of the capital at risk as prescribed under the Insurance (Margin of Solvency) Rules (which is generally 4% of the mathematical reserves and 0.3% of the capital at risk). For a long-term insurer, under the current law, the value of its assets must be greater than the amount of its liabilities by at least the required solvency margin. The minimum paid-up capital for insurers in Hong Kong is HKD$10 million. In practice, the actual capital requirement is much higher than what the law requires, and will also depend on the business undertaken by the insurer. Despite the above, in practice, the IA will also impose additional solvency requirements to ensure a sound and healthy insurance market.
The Insurance (Amendment) Ordinance 2023 (the “Amendment Ordinance”), which is expected to be implemented in 2024, will substantially amend the solvency margin and capital requirements applicable to Hong Kong insurers, among other requirements. The Amendment Ordinance introduces a statutory basis for the implementation of the RBC regime in Hong Kong, under which an insurer’s capital adequacy will be assessed on the basis of its risk profile rather than on the basis of its solvency margins. For example, an insurer’s capital will be required to meet both a “prescribed capital amount” requirement (which is expected to be a value-at-risk measure of the capital required to ensure non-negative net assets, taking into account the risks faced by the insurer’s business) and a “minimum capital amount” requirement. It is expected that the IA will further consult the industry before promulgating detailed rules regarding the calculation of such amounts and the technical requirements of the RBC regime. Such detailed rules and requirements will be introduced through regulations issued under the Insurance Ordinance. SLHK received approval from the IA for early adoption of the RBC regime on August 14, 2023.
Malaysia
Our operations in Malaysia offer individual and group insurance and takaful products through Sun Life Malaysia Assurance Berhad ("SLMA") and Sun Life Malaysia Takaful Berhad ("SLMT"), respectively, our joint ventures with Renggis Ventures Sdn. Bhd. (a subsidiary of Khazanah Nasional Berhad), in which we have a 49% ownership stake in each company. SLMA has an exclusive bancassurance agreement with CIMB Bank Berhad to distribute insurance products through its network across Malaysia, while SLMT has an exclusive bancatakaful agreement with CIMB Islamic Bank Berhad to distribute takaful products through its network across Malaysia. The companies have expanded their distribution channel to include other bancassurance and bancatakaful partners, agency distribution, direct marketing, government and corporate business, telemarketing, online and telco-assurance.
The central bank of Malaysia, Bank Negara Malaysia ("BNM"), regulates entities carrying on the insurance and takaful business in Malaysia and requires insurers and takaful operators to have a minimum paid-up capital of Ringgit Malaysia 100 million. BNM also requires insurers and takaful operators to maintain a capital adequacy level that is commensurate with their risk profiles under the risk-based capital frameworks and has set a minimum Supervisory Target Capital Level of 130%. Based on current Government policy, there is a 70% limit on foreign equity ownership in insurance companies and takaful operators in Malaysia.

Under the BNM's Discussion Paper on Risk-Based Capital Framework for Insurers and Takaful Operators (Framework Design) (the "Discussion Paper") issued in June 2021, several enhancements have been proposed to the design of the capital adequacy framework for licensed insurers and takaful operators ("ITO"). Feedback has been sought from ITOs and a quantitative impact study was performed in 2022 to collect data for further analysis and refinement of the proposed new framework design. The Discussion Paper is part of a phased approach toward refining the capital adequacy requirements applicable to ITOs. A new framework reflecting the revised approach is expected to be implemented in 2025.

Other Jurisdictions
In each of the countries in which our other subsidiaries, joint ventures and associates operate, local regulatory authorities supervise and monitor their business and financial condition. In a number of countries, certain insurance subsidiaries, joint ventures and associates are required to meet specific minimum working and regulatory capital requirements. Certain of our subsidiaries (including MFS, BentallGreenOak, InfraRed and/or their respective subsidiaries), joint ventures and associates, also conduct business in various countries, including Japan and Australia, that are subject to applicable laws and regulations, which vary from country to country.

Risk Factors
This section provides a summary of some of the significant risks that could affect (and, in some cases, are affecting) our business, reputation, financial condition or results of operations. As a large financial services organization operating in a complex industry, the Company encounters a variety of risks and uncertainties. We face risks in formulating our business strategy and business objectives, in carrying on our business activities in the pursuit of our strategy and objectives, and from external factors such as changes in the economic, geopolitical, competitive, environmental, social and regulatory landscape. We are subject to financial and insurance risks that are connected to our liabilities and also in connection with the management and performance of our assets, including how we match returns from assets with the payment of liabilities to our Clients. Each of these risks are also considered from the perspective of different types of uncertainties under which either the outcomes and/or their probabilities of occurrence are unknown. Uncertainty can exist around expected financial results and from volatility, trend and extreme events. In addition, risk correlation, interconnected risks, terms of exposure and the risk horizon are important elements to consider while identifying risks.

These risk factors have been grouped as outlined in our Risk Management Framework into six major categories: market, insurance, credit, business and strategic, operational and liquidity risks. Other risks, not specified below, may exist but are not considered to be material at the present time may also impact our business in the future. This information should be considered carefully together with other information in this AIF and in the 2023 MD&A, the 2023 Consolidated Financial Statements and other reports and materials that we file with securities regulators.
These risks may occur independently or in combinations, and may occur simultaneously or in an environment where one or more risks evolve rapidly. For example, a major pandemic could have a material adverse impact on mortality and morbidity claims experience. Such an event may also trigger adverse global capital markets developments, including a downturn in equity market levels and interest rates, increased market volatility and credit deterioration, and could also lead to operational risks such as disruptions within the organization and in third party service arrangements or a government or regulatory response.
While a number of risks that are described below provide examples of inter-connectedness and relationships between risks, these do not represent a complete inventory. It should be noted that these relationships can continue to develop and change over time, and the combined adverse impact on our profitability, financial position, and reputation could be significantly greater than the sum of the individual parts. Our assessment of the impact and probability of these risks changes over time.
A description of our risk management approach can be found under the heading Risk Management in our 2023 MD&A. Many of the risk factors set out below contain forward-looking statements.

Market Risk
We are exposed to market risk, which is defined as the risk that the value or future cash flows of insurance and investment contract liabilities or financial assets will fluctuate because of changes or volatility in market prices. Market risk includes equity, interest rate and spread, real estate, foreign currency, and inflation risks.

We have implemented asset-liability management and hedging programs involving regular monitoring and adjustment of market risk exposures using assets, derivative instruments and repurchase agreements to maintain market risk exposures within our risk appetite. The general availability and cost of these hedging instruments may be adversely impacted by a number of factors including changes in interest rates, increased volatility in capital markets, and changes in the general market and regulatory environment within which these hedging programs operate. In particular, regulations for derivatives could impose additional costs and could affect our hedging strategy. In addition, these programs may themselves expose us to other risks.
Sun Life Financial Inc. | sunlife.com                                           34

             Annual Information Form 2023
Equity Risk
Equity risk is the potential for financial loss arising from declines or volatility in equity market prices. We are exposed to equity risk from a number of sources

We generate revenue in our asset management businesses and from certain insurance and annuity contracts where fees are levied on account balances that are affected directly by equity market levels. Accordingly, we have further exposure to equity risk as adverse fluctuations in the market value of such assets will result in corresponding adverse impacts on revenue, income, and the contractual service margin. In addition, declining and volatile equity markets may have a negative impact on sales and redemptions (surrenders) in these businesses, and this may result in further adverse impacts on net income, the contractual service margin, and capital.

A portion of our exposure to equity risk arises in connection with benefit guarantees on segregated fund products, some participating insurance contracts, some adjustable insurance contracts, and some universal life contracts. These benefit guarantees may be triggered upon death, maturity, withdrawal or annuitization. The cost of providing these guarantees is uncertain and depends upon a number of factors, including general capital market conditions, our hedging strategies, policyholder behaviour and mortality experience, each of which may result in negative impacts on net income, the contractual service margin, and capital.

While a large percentage of contracts are included in the hedging program, not all of our market risk exposure related to these contracts is hedged. For those segregated fund contracts included in the hedging program, we generally hedge the value of expected future net claims costs and associated risk adjustments for non-financial risk. The general availability and cost of these hedging instruments may be adversely impacted by a number of factors, including changes in interest rates, increased volatility in capital markets and changes in the general market and regulatory environment within which these hedging programs operate.

Our hedging programs may themselves expose us to other risks, including basis risk, volatility risk, and increased levels of derivative counterparty credit risk, liquidity risk, model risk and other operational risks. These factors may adversely impact the net effectiveness, costs, and financial viability of maintaining these hedging programs and therefore adversely impact our profitability and financial position. While our hedging programs are intended to mitigate these effects (e.g., hedge counterparty credit risk is managed by maintaining broad diversification, dealing primarily with highly-rated counterparties, and transacting through OTC contracts cleared through central clearing houses, exchange-traded contracts or bilateral OTC contracts negotiated directly between counterparties that include credit support annexes), residual risk, potential reported earnings and capital volatility remain.

We also have direct exposure to equity markets from the investments supporting other general account liabilities, surplus, and employee benefit plans. These exposures fall within our risk-taking philosophy and appetite, and are therefore generally not hedged.

Interest Rate and Spread Risk
Interest rate and spread risk includes the potential for financial loss arising from changes in the value of insurance and investment contract liabilities and financial assets due to changes or volatility in interest rates or spreads. In practice, when asset cash flows and the policy obligations they support are not matched, this may result in the need to either sell assets to meet policy payments and expenses or reinvest excess asset cash flows in unfavourable interest rate or credit spread environments. This risk is managed in our asset-liability management program. Details of the asset-liability management program are discussed under the heading "Market Risk Management Governance and Control" in section K - Risk Management in our 2023 MD&A.
Our primary exposure to interest rate and spread risk arises from insurance and investment contracts that contain guarantees in the form of minimum crediting rates, maximum premium rates, settlement options, guaranteed annuitization options and minimum benefits. If investment returns fall below guaranteed levels, we may be required to increase liabilities or capital in respect of these contracts. The guarantees attached to these products may be applicable to both past premiums collected and future premiums not yet received. Segregated fund contracts provide benefit guarantees that are linked to underlying fund performance and may be triggered upon death, maturity, withdrawal or annuitization. Exposure to guarantees is managed within our risk appetite limits through our asset-liability management program, which may include the use of hedging strategies utilizing interest rate derivatives such as interest rate floors, swaps, futures and swaptions. The impact of these guarantees on net income, contractual service margin, and capital are included in the disclosed market risk sensitivities.

Significant changes or volatility in interest rates or spreads could have a negative impact on sales of certain insurance and annuity products, and adversely impact the expected pattern of redemptions (surrenders) on existing policies. Increases in interest rates or widening credit spreads may increase the risk that policyholders will surrender their contracts, potentially forcing us to liquidate assets at a loss. While we have established hedging programs in place and our insurance and annuity products often contain surrender mitigation features, these may not be sufficient to fully offset the adverse impact of changes in interest rates or spreads. Declines in interest rates or narrowing spreads can result in compression of the net spread between interest earned on investments and interest credited to policyholders. Declines in interest rates or narrowing
Sun Life Financial Inc. | sunlife.com                                           35

             Annual Information Form 2023
spreads can also result in increased asset calls, mortgage prepayments, and net reinvestment of positive cash flows at lower yields, and therefore adversely impact our profitability and financial position. Negative interest rates may additionally result in losses on our cash and short-term deposits and low or negative returns on our fixed income assets impacting our profitability.

We also have direct exposure to interest rates and spreads from investments supporting other general account liabilities, surplus and employee benefit plans. Higher interest rates or wider spreads will reduce the value of our existing assets. Conversely, lower interest rates or a narrowing of spreads will result in reduced investment income on new fixed income asset purchases. These exposures fall within our risk-taking philosophy and appetite and are therefore generally not hedged.

A sustained low interest rate environment may additionally adversely impact our net income, contractual service margin, capital, and our ability to implement our business strategy and plans. This may be realized through lower sales, less profitable new business, changes in the pattern of redemptions on existing policies, among other impacts.

Real Estate Risk
Real estate risk is the potential for financial loss arising from fluctuations in the value of, or future cash flows from, our investments in real estate. We are exposed to real estate risk and may experience financial losses resulting from the direct ownership of real estate investments or indirectly through fixed income investments secured by real estate property, leasehold interests, ground rents, and purchase and leaseback transactions. Real estate price risk may arise from external market conditions, inadequate property analysis, inadequate insurance coverage, inappropriate real estate appraisals, or from environmental risk exposures. We hold real estate investments that support general account liabilities and surplus, and fluctuations in value will affect our net income, contractual service margin, and capital. A material and sustained increase in interest rates may lead to deterioration in real estate values.

Foreign Currency Risk
Foreign currency risk is the result of mismatches in the currency of our assets and liabilities (inclusive of capital), and cash flows. This risk may arise from a variety of sources such as foreign currency transactions and services, foreign currency hedging, investments denominated in foreign currencies, investments in foreign subsidiaries and net income from foreign operations. Changes or volatility in foreign exchange rates, including a change to currencies that are fixed in value to another currency, could adversely affect our net income, contractual service margin and capital.

As an international provider of financial services, we operate in a number of countries, with revenues and expenses denominated in several local currencies. In each country in which we operate, we generally maintain the currency profile of assets to match the currency of liabilities and required capital. This approach provides an operational hedge against disruptions in local operations caused by currency fluctuations. Foreign currency derivative contracts such as currency swaps and forwards are used as a risk management tool to manage the currency exposure in accordance with our Asset Liability Management Policy. As at December 31, 2023 and December 31, 2022, the Company did not have a material foreign currency risk exposure.

Changes in exchange rates can affect our net income and surplus when financial results in functional currencies are translated into Canadian dollars. Net income earned outside of Canada is generally not currency hedged and a weakening in the local currency of our foreign operations relative to the Canadian dollar can have a negative impact on our net income reported in Canadian currency. A strengthening in the local currency of our foreign operations relative to the Canadian dollar would have the opposite effect. Regulatory capital ratios could also be impacted by changes in exchange rates.

Inflation Risk
Inflation risk is the potential for financial loss arising from changes in inflation rates. This risk results from insurance contract liabilities that are linked to market measures of inflation such as the Consumer Price Index. The primary sources for this risk exposure are from certain group and retail annuity contracts and group long term disability contracts. In these contracts, the annuity and disability benefit payments may be linked to an indexing formula containing an inflation price index. Benefit payments linked to inflation indices may also include various caps, floors and averaging mechanisms that vary across product designs.

Exposure to inflation risk is managed within our asset-liability management program, primarily by investing in inflation linked assets to match liability exposures.
The impact of inflation on general account expenses is discussed in Risk Factors - Expense Risk in this Annual Information Form.

Insurance Risk
Insurance risk is the uncertainty of product performance due to actual experience emerging differently than expected in the areas of mortality, morbidity and longevity. In addition, policyholder behaviour, product design and pricing, expense and reinsurance risks impact multiple risk categories, including insurance risk.

Sun Life Financial Inc. | sunlife.com                                           36

             Annual Information Form 2023
Policyholder Behaviour Risk
We can incur losses due to adverse policyholder behaviour relative to the assumptions used in the pricing and valuation of products regarding lapse of policies or exercise of other embedded policy options.

Uncertainty in policyholder behaviour can arise from several sources including unexpected events in the policyholder's life circumstances, the general level of economic activity (whether higher or lower than expected), changes in the financial and capital markets, changes in pricing and availability of current products, the introduction of new products, changes in underwriting technology and standards, as well as changes in our financial strength or reputation. Uncertainty in future cash flows affected by policyholder behaviour can be further exacerbated by unexpected behaviour during times of economic turbulence or at key option exercise points in the life of an insurance contract.

Many of our products include some form of embedded policyholder option. These could range from simple options relating to surrender or termination, to more complex options relating to payment of premiums or various other benefit and coverage provisions. Changes in the relative frequency or pattern with which these options are elected (relative to those assumed in the pricing and valuation of these options) could have an adverse impact on our profitability and financial position.

Systemic forms of policyholder behaviour risk could also arise with the development of investor-owned and secondary markets for life insurance policies.

Mortality and Morbidity Risk
Mortality and morbidity risk is the risk that future experience could be unfavourable relative to the assumptions used in the pricing and valuation of products. Mortality and morbidity risk can arise in the normal course of business through random fluctuation in realized experience, through catastrophes, as a result of a pandemic, or in association with other risk factors such as product development and pricing risk. Adverse mortality and morbidity experience could also occur through systemic anti-selection, which could arise due to poor plan design, or underwriting process failure or the development of investor-owned and secondary markets for life insurance policies.

External factors could adversely affect our life insurance, health insurance, critical illness, disability, long-term care insurance and annuity businesses. Morbidity experience could be unfavourably impacted by external events, such as pandemics, increases in disability claims during economic slowdowns and increases in high medical treatment costs and growth in utilization of specialty drugs. This introduces the potential for adverse financial results.

Mortality and morbidity concentration risk is the risk of a catastrophic event, such as natural environmental disasters (for example, earthquakes), human-made disasters (for example, acts of terrorism, military actions, and inadvertent introduction of toxic elements into the environment) as well as epidemics that could occur in geographic locations where there is significant insurance coverage. Certain factors could adversely affect our mortality or morbidity experience relative to the assumptions used in the pricing and valuation of products, leading to a material adverse effect on our profitability and financial position.

Current legislation restricts insurers from requiring policyholders to take or release the results of genetic tests. If policyholders have access to the results of genetic tests and we do not, this creates asymmetry of information between policyholders and insurers, which could adversely impact mortality and morbidity experience and policyholder behaviour. This asymmetry of information may increase as genetic testing advances and becomes more accessible, giving rise to better diagnoses of conditions where treatments are expensive or non-existent. The asymmetry of information may lead to increased anti-selection in new business underwriting. There may also be an impact on policy lapse rates where adverse genetic testing results may motivate policyholders to retain their policies resulting in higher claims payouts than assumed in the pricing and valuation of products, as well as increased insurance rates which may result in loss of new and existing policyholders.

Longevity Risk
Longevity risk is the potential for losses arising from adverse changes in rates of mortality improvement relative to the assumptions used in the pricing and valuation of products. This risk can manifest itself slowly over time as socioeconomic conditions improve and medical advances continue. It could also manifest itself more quickly, for example, due to medical breakthroughs that significantly extend life expectancy. Longevity risk affects contracts where benefits or costs are based upon the likelihood of survival and higher than expected improvements in insured life expectancy could therefore increase the ultimate cost of these benefits (for example, annuities, pensions, pure endowments, some segregated funds, and specific types of health contracts).

Many of our products provide benefits over the policyholder's continued lifetime. Higher than expected improvements in policyholder life expectancy could therefore increase the ultimate cost of these benefits, thereby requiring strengthening of policyholder liabilities and resulting in reductions in net income and capital. For longevity risks, external factors including
Sun Life Financial Inc. | sunlife.com                                           37

             Annual Information Form 2023
medical advances could adversely affect our life insurance, health insurance, critical illness, disability, long-term care insurance and annuity businesses.

Product Design and Pricing Risk
Product design and pricing risk is the risk a product does not perform as expected, causing adverse financial consequences. This risk may arise from deviations in realized experience versus assumptions used in the pricing of products. Risk factors include uncertainty concerning future investment yields, policyholder behaviour, mortality and morbidity experience, sales levels, mix of business, expenses and taxes. Although some of our products permit us to increase premiums or adjust other charges and credits during the life of the policy or contract, the terms of these policies or contracts may not allow for sufficient adjustments to maintain expected profitability. This could have an adverse effect on our profitability and capital position.

Products that offer complex features, options or guarantees require increasingly complex pricing models, methods or assumptions, leading to additional levels of uncertainty. The risk of mis-pricing increases with the number and inherent uncertainty of assumptions needed to model a product. Past experience data supplemented with future trend assumptions may be poor predictors of future experience. Lack of experience data on new products or new Client segments increases the risk that future actual experience unfolds differently from expected assumptions. External environmental factors may introduce new risk factors, which were unanticipated during product design, and have an adverse result on the financial performance of the product. Policyholder sophistication and behaviour in the future may vary from that assumed at the time the product is designed, thereby adversely affecting the product's financial performance.

Expense Risk
Expense risk is the risk that future expenses are higher than the assumptions used in the pricing and valuation of products. This risk can arise from general economic conditions, unexpected increases in inflation, slower than anticipated growth, or reduction in productivity leading to increases in unit expenses. Expense risk occurs in products where we cannot or will not pass increased costs onto the policyholder and will manifest itself in the form of a liability increase or a reduction in expected future profits.

From time to time, certain products or business segments may be closed for new sales (for example, individual insurance business in the U.S.). Our ability to effectively manage the run-off of business in these products or business segments introduces additional risks, such as policyholder behaviour and expense risk that may have an adverse effect on our operations, profitability and financial position.

Reinsurance Risk
We purchase reinsurance for certain risks underwritten by our various insurance businesses. Reinsurance risk is the risk of financial loss due to adverse developments in reinsurance markets (for example, discontinuance or diminution of reinsurance capacity, or an increase in the cost of reinsurance), insolvency of a reinsurer or inadequate reinsurance coverage. While reinsurance arrangements provide for the recovery of claims arising from the liabilities ceded, we retain primary responsibility to the policyholders.

Rates for our in-force reinsurance treaties can be either guaranteed or adjustable for the life of the ceded policy. Changes in reinsurance market conditions, including actions taken by reinsurers to increase rates on existing and new coverage and our ability to obtain appropriate reinsurance, may adversely impact the availability or cost of maintaining existing or securing new reinsurance capacity, with adverse impacts on our business strategies, profitability and financial position. There is a possibility of rate increases or renegotiation of some of the legacy reinsurance contracts by our reinsurers, as the global reinsurance industry continues to review and optimize their business models. In addition, changes to the regulatory treatment of reinsurance arrangements could have an adverse impact on our capital position.

Credit Risk
Credit risk is the possibility of loss from amounts owed by our borrowers or financial counterparties. We are subject to credit risk in connection with issuers of securities held in our investment portfolio, debtors, structured securities, reinsurers, counterparties (including derivative, repurchase agreement and securities lending counterparties), other financial institutions and other entities. Losses may occur when a counterparty fails to make timely payments pursuant to the terms of the underlying contractual arrangement or when the counterparty's credit rating or risk profile otherwise deteriorates. Credit risk can also arise in connection with deterioration in the value of, or ability to realize, any underlying security that may be used as collateral for the debt obligation. Credit risk can occur as a result of broad economic conditions, challenges within specific sectors of the economy, or from issues affecting individual companies. Events that result in defaults, impairments or downgrades of the securities in our investment portfolio would cause the Company to record realized or unrealized losses and may cause an increase in our provisions for asset default, adversely impacting earnings.

Volatility in the capital markets, including deteriorating credit and negative real estate risk indicators, fluctuations in global or domestic macro-economic factors, or loss given default expectations, may have a significant impact on the value of the
Sun Life Financial Inc. | sunlife.com                                           38

             Annual Information Form 2023
fixed income assets in our investment portfolio. For example, our asset-backed portfolio is sensitive to fluctuations in macro-economic factors, assumed default rates for the underlying collateral pool and loss given default expectations.

As part of our risk management strategy, we maintain hedging programs that may employ the use of derivatives. Market conditions determine the availability and cost of the derivative protection. Although we deal primarily with highly rated counterparties, a derivative counterparty's insolvency or its inability or unwillingness to make payments under the terms of a derivative agreement could have an adverse effect on our profitability and financial position.

We purchase reinsurance for certain risks underwritten by our various insurance businesses. Reinsurance does not relieve us from our direct liability to policyholders and accordingly, we bear credit risk with respect to our reinsurers. Although we deal primarily with highly rated reinsurers, deterioration in their credit ratings, or reinsurer insolvency, inability or unwillingness to make payments under the terms of a reinsurance agreement could have an adverse effect on our profitability and financial position. The risk that a reinsurer is unable or unwilling to make payments may occur due to, but is not limited to, legal disagreements, interpretations by a court regarding the terms of the reinsurance contract, changes in laws and regulations or interpretation of those changes.

Business and Strategic Risk
Business and strategic risk is the risk of loss from the inability to adequately identify, plan or implement an appropriate strategy to achieve strategic and business objectives or adapt to changes in Client behaviours, the external business, economic, geopolitical, regulatory or environmental and social landscape or when assumptions made in strategy are not realized as expected.
Geopolitical Risk
Geopolitical risk is the wide array of risks associated with conflict or tensions between states as well as events or trends with global or international dimensions that increase risks for the operations of companies. We operate in various geographies and our business and financial operations are susceptible to regional and global economic, geopolitical and regulatory changes. Geopolitical risk may lead to increased volatility in the global capital and energy markets, difficulty in conducting business in certain geographies, an increased threat of targeted cyber-attacks, and has the potential to introduce reputational risk.
Currently, there are various factors that impact geopolitical risk and uncertainty, including but not limited to the following examples:
•Elevated geopolitical risk exemplified by ongoing active conflicts in the Middle East, between Israel and Hamas, and in Europe, between Russia and Ukraine, as well as risks associated with China-Taiwan tensions;
•Ongoing potential impacts to trade and/or new or increased tariffs from an increase in protectionist tendencies and national industrial policies;
•Rising populism across many key markets, including the US, where presidential elections will add to uncertainty;
•Strategic competition between the US and China, especially in technology.
Economic Risk
We may be affected by economic and capital markets conditions and economic shocks around the globe as a result of increasingly connected global markets. Factors such as changes in interest rates, foreign exchange rates, market volatility, housing prices, consumer spending, saving and debt, business investment and inflation around the globe can affect the business and economic environments in which we operate. In addition, adverse economic conditions often arise in conjunction with volatile and deteriorating capital markets conditions, which can have an adverse impact on Client behaviour, our sales and profitability, credit and financial strength ratings, and capital and liquidity positions.

Currently, there are various factors that impact economic risk and uncertainty, including but not limited to the following examples:
•Increase in commercial and corporate bankruptcies as businesses deal with higher borrowing costs;
•Hybrid/ work from home operating model has led to higher vacancy rates and is causing stress in the North America commercial real estate sector;
•Higher interest rates for longer period as Central Banks work to bring inflation back in line with the target, and persistent high levels of inflation against a backdrop of financial market volatility, labour market distortions, supply chain disruptions, corporate insolvency risks and household wealth impacts, all of which may lead to a global economic slowdown; and
•Rising income inequality.

Continued economic uncertainty may give rise to increased business and strategic risks including those associated with industry restructuring, mergers and acquisitions, changing competitive dynamics and changes in the legal, regulatory and tax regimes in which our businesses operate. Economic risk can also intersect with other risk considerations such as environmental and social risks including climate change and inequality. The impact of these factors include the possibility of continued low growth, sustained low interest rates, increases in inflation, increased volatility in interest rates and equity markets, and a continuation of relatively low yet volatile credit spreads. The impact on the economic environment from any of these events may not be consistent with our assumptions and expectations, which may adversely impact our financial results and the ability to implement our business strategy. Market-related impacts from the economic environment, legal, regulatory
Sun Life Financial Inc. | sunlife.com                                           39

             Annual Information Form 2023
or policy changes or other governmental actions could continue to place pressure on our earnings, regulatory capital requirements, profitability, liquidity and our ability to implement our business strategies and plans. Low interest rates and increased volatility create a number of challenges for us including increased hedge costs, lower investment yields, adverse policyholder behaviour and lower levels of new business profitability. Other impacts of macro-economic uncertainty and volatility may lead to other financial and non-financial impacts including goodwill impairment, decline in our share price and impact on our credit and financial strength ratings.
Execution Risk
Our business strategies and plans are dependent on the successful execution of organizational and strategic initiatives designed to support the growth of our business. Our ability to manage the execution of these initiatives effectively and prioritize initiatives directly affects our ability to execute our strategies. Identifying and implementing the right set of initiatives is critical to achieving our Business Plan targets. Failure to identify and implement the right set of initiatives could also lead to cost structure challenges and inability to achieve our growth objectives.

Our financial performance is dependent upon our ability to implement and execute our business strategies and plans for growth. The current economic, regulatory and competitive environment requires us to identify and adapt rapidly to new opportunities and to refine our strategies. If we fail to identify new opportunities, revise our strategies on a timely basis or adapt to the changing environment, we may not be able to achieve our growth objectives.

Successful execution of our business strategies and plans impacts a number of factors, including our ability to generate sufficient earnings to maintain an adequate level of capital, our ability to generate sustained investment performance, our ability to meet regulatory requirements, our ability to manage our risk exposures effectively, our ability to attract and retain Clients and distributors, our ability to have the right set of diverse products and business mix, and our ability to reduce operating expenses while maintaining our ability to hire, retain and motivate key personnel. There is no certainty that we will be successful in implementing our business strategies or that these strategies will achieve our objectives. If our business strategies are not successful or are not executed effectively, we may not be able to achieve our growth objectives or react to market opportunities, which may have an adverse impact on our business and financial results.
Distribution Risk
Failure to achieve planned distribution scale could materially impact our financial and strategic objectives. This includes the inability to attract and retain intermediaries and agents at a cost that is financially feasible to the Company, or to develop online sales and Client support capabilities and technologies. Distribution risk may also be influenced where our distribution or product strategy and related services (including online sales and Client support capabilities and technologies) are not developed, modified or executed in line with our strategic objectives or in consideration of the changes in Client behaviour or our regulatory environment. In addition, the lack of a well-diversified distribution model in the jurisdictions in which we do business may cause over-reliance on agency channel or key partners.

We distribute our products through a variety of distribution channels, including direct sales agents, managing general agents, independent general agents, financial intermediaries, broker-dealers, banks, pension and benefits consultants and other third-party marketing organizations. We compete with other financial institutions to attract and retain these intermediaries and agents on the basis of products, compensation, support services and financial position. We also face the risk that our key distribution partners may undergo consolidation, change in ownership structure or change their distribution model which could materially impact sales and our growth targets. New distribution channels could emerge that may impact the effectiveness of our current distribution strategy. Distribution channels are growing rapidly in some businesses in certain countries, which may heighten the risks of market conduct and channel conflicts or overlaps. The capability to reach and retain Clients through use of digital technology and data analytics is becoming increasingly important in the insurance industry. While use of digital-based distribution channels may help us achieve or expand scale, these channels expose us to regulatory compliance and information security related risks. Our sales and results of operations could be materially adversely affected if we do not have the right distribution or product strategy and related technology or if we are unsuccessful in attracting and retaining intermediaries and agents.
Risks Relating to Mergers, Acquisitions, Divestitures and Strategic Investments
We regularly explore opportunities to selectively acquire other businesses or to divest ourselves of all or part of certain businesses, in support of our growth and strategic objectives. Any transaction carries risks associated with economic, operational, strategic, financial, tax, legal, regulatory, compliance, environmental and social, and other factors.

There is a risk that we may be unable to make an appropriate acquisition in a desired market or business line or unable to realize the financial and strategic benefits of the transactions due to competitive factors, regulatory requirements or other aspects. There is a risk that the capital utilized to finance any transaction may limit our ability to deploy further capital to pursue other opportunities and initiatives. These risks could adversely impact our ability to achieve our financial and strategic objectives.

Our ability to realize the contemplated economic, financial, and strategic benefit of any transaction that we enter into is contingent on several factors. These include the effective separation and/or integration of the transferred businesses, restructure and/or reorganization of related businesses, and retention of key personnel to effectively execute these
Sun Life Financial Inc. | sunlife.com                                           40

             Annual Information Form 2023
transactions. In addition, post-closing activities and the harmonization of any differences in organizational culture may require the dedication of significant management resources, which may distract management’s attention from our day-to-day business. Further, anticipated synergies and other benefits may not materialize due to a failure to successfully integrate the acquired businesses with our existing operations. Any of these risks, if realized, could prevent us from achieving the expected outcomes from a transaction and impact our financial and strategic objectives.

Although we undertake extensive due diligence in connection with potential acquisitions, there may be liabilities or asset impairments that we fail to, or are unable to, discover during our due diligence investigations. There could also be unforeseen liabilities or asset impairments, including goodwill impairments that arise in connection with acquisitions or divestitures of businesses. There is no assurance that we will achieve our financial or strategic objectives or anticipated cost savings following an acquisition.

The purchase and sale agreements that support mergers and acquisitions transactions typically include customary indemnifications provided by the seller to the purchaser. These rights are generally limited by survival periods and include limitations on the nature and amount of losses we may recover as a purchaser or be required be pay as a seller in a transaction. For your acquisitions, there is a risk that these indemnifications will not be collectible or be sufficient to fully offset losses arising from the acquired business. We would also be exposed to the credit risk of the selling party with respect to its ability to pay if an indemnification provision is triggered.
Competitive Environment
Competition from insurance companies, banks, asset managers, mutual fund companies, financial planners and other service providers (including new entrants and non-traditional financial services companies) is intense, and could adversely affect our business in certain countries.

The businesses in which we engage are highly competitive and our ability to sell our products is dependent on many factors, including scale, price and yields offered, distribution channels, digital capabilities, financial strength ratings, range of product lines and product and service quality, brand strength, investment performance, historical dividend levels and the ability to provide value added services to distributors and Clients. In certain markets, some of our competitors may be superior to us on one or more of these factors. Our competitors have significant potential to disrupt our business through targeted strategies to reduce our market share which may include targeting our key people or bancassurance partners and other distributors or aggressively pricing their products. Our ability to achieve our Business Plans and strategies depends significantly upon our capacity to anticipate and respond quickly to these competitive pressures.

Technology is driving rapid change in the financial services sector and is enabling new entrants to compete or offer services to our competitors to enhance their ability to compete in certain segments of the insurance, wealth and asset management markets. The emergence of new technologies such as robotic process automation, artificial intelligence, blockchain and advanced analytics may have an impact on the financial services sector and how companies interact with their stakeholders. Our current competitors or new entrants may use these or other new technologies to provide services in various areas such as customized pricing, proactive outreach to Clients and targeted marketing in order to strengthen their Client relationships and influence Client behaviour. The impact of disruption from changing technology and innovation by traditional and non-traditional competitors who may offer a better user experience, functionality or lower priced products and may have lower distribution costs will require us to adapt at a more rapid pace and may create margin pressures. The risk of disruption may also impact our distribution models as new and low cost digital-based business models emerge in connection with the distribution of financial services and products, such as insurtechs and robo-advisors. These risks are evolving rapidly with an increasing number of digital users and are difficult to anticipate and respond to proactively, and may adversely impact our profitability and financial position.

Competitors may offer a greater selection of or lower cost products, which may create margin pressure in some of our businesses and impact our profitability and market share. In the asset management sector, there has been a trend among investors towards lower-fee passive investment products such as index- and other types of exchange-traded funds, which may impact our ability to attract and retain Clients in our actively managed products. Product development and product life cycles have shortened in many product segments, leading to more intense competition with respect to product features. This increases product development and administrative costs and reduces the time frame over which capital expenditures can be recovered. Regulatory and compliance costs also generally rise with increases in the range and complexity of our product portfolio.

We have many large and well-capitalized competitors with access to significant financial resources and in certain jurisdictions, these competitors have significant market share and established distribution relationships and brands. Among other things, the competition in these industries throughout the world has resulted in a trend towards the global consolidation of the financial services industry including, in particular, the insurance, banking and asset management sectors. To the extent that consolidation continues, we will increasingly face competition from large, well-capitalized financial services companies in many of the jurisdictions in which we operate. These larger companies have the ability to heavily invest in fundamental activities for sustained profitable growth and superior Client service in the life insurance industry such as brand equity, product development, technology, risk management, and distribution capability. There can be no assurance these developments will not adversely affect our businesses in certain countries.
Sun Life Financial Inc. | sunlife.com                                           41

             Annual Information Form 2023

Many of our insurance products, particularly those offered by the group segment, are renewed annually. Given this relatively high frequency of renewal activity, this business may be particularly exposed to adverse persistency through competitive market pressures.

Different accounting bases of reporting and regulatory capital requirements across multiple jurisdictions may cause us to be at a disadvantage compared to some of our competitors due to differences in reported earnings and due to these reporting and regulatory capital requirements.
Investment Performance
Investment performance risk is the possibility that we fail to achieve the desired return objectives on our investment portfolio, or that our asset management businesses fail to design or execute investment strategies in order to achieve competitive returns on the products and managed accounts offered by these businesses. Failure to achieve investment objectives may adversely affect our revenue and profitability through slower growth prospects and adverse impacts on policyholder or Client behaviour.

For our insurance businesses, the performance of our investment portfolio depends in part upon the level of and changes in interest rates, spreads, credit experience, equity prices, real estate values, the performance of the economy in general, the performance of the specific obligors included in these portfolios and other factors that are beyond our control. These changes can affect our net investment income substantially in any period.

In our asset management businesses, investment performance, along with achieving and maintaining superior distribution and Client services, is critical. If investment performance is less than that of our competitors or applicable benchmarks, we could lose existing and potential Clients. Similarly, a shift in investing trends and Client preference towards products that differ from our investment products or strategies, and in particular, the trend towards passive or alternative investment portfolios, could also lead to increased outflows. Accordingly, poor investment performance by our asset management operations or a shift in investing trends and Client preferences could adversely affect sales, increase outflows, reduce the level of assets under management or lead to a decline in the fee margin, which could adversely impact our revenues, income and capital position.
Changes in Legal and Regulatory Environment
Most of our businesses are subject to extensive regulation and supervision. Changes to legislation, regulations or government policies, or the manner in which they are interpreted or enforced, may require that we make significant changes to our strategy and may result in increased implementation costs and diversion of resources to manage the change. These changes could impact financial reporting, accounting processes, capital requirements, the regulatory framework for our products and services, the regulation of selling practices, sales intermediaries and product offerings, solvency requirements, executive compensation, and corporate governance practices and could impose restrictions on our foreign operations (such as limits on foreign ownership of local companies). All of these changes could have an adverse effect on our business and operations. Our failure to comply with existing and evolving regulatory requirements could also result in regulatory sanctions and could affect our relationships with regulatory authorities and our ability to execute our business strategies and plans.

Currently there are a number of regulatory developments in Canada and globally which could impact our business and the way we are regulated or supervised in various jurisdictions, which include the following:
•OSFI is considering alternatives for in-force variable annuity and segregated fund capital requirements, to be effective January 1, 2025, which may materially change the capital required to support our in-force variable annuity and segregated fund business.
•OSFI has published the final version of the Parental Stand-Alone (Solo) Capital Framework (the “Solo Framework”) for federally regulated life insurance companies, which may materially change our capital management policies and structures. The Solo Framework allows OSFI to assess the stand-alone loss-absorbing capacity of SLF Inc. as parent company effective January 1, 2024, with applicable disclosures required to be published beginning in the first quarter of 2025.
•In Canada, there has been increased focus on enhancing the affordability of and accessibility to prescription drugs and dental procedures, including pressure on the federal government from political parties, some provincial governments, the media and advocacy groups to implement forms of nationalized pharmacare and dentalcare programs. When implemented, these programs could impact our business in several ways, including premium income, our ability to offer coverage, the price and level of coverage of other benefits we offer or are able to offer through our Canadian group benefits business, which in turn could impact plan renewals and retention of group Clients, plan member interaction and the value of other coverage offered by that business.
•Insurance and securities regulators continue to focus on client fairness, advisor conduct and related practices and are assessing product fees, compensation practices, sales practices and conflicts of interest. Regulators are also imposing higher standards that relate to interacting with clients in order to increase disclosure obligations related to fees; impose prohibitions or restrictions on the payment of certain types of commissions and service fees to agents, advisors and third-party distributors; resulting in changes to product features and sales and market practices by agents, advisors, product manufacturers and distributors. Examples of these changes include the Client Focused Reforms released by the Canadian Securities Administrators which fully came into effect on December 31, 2021, the
Sun Life Financial Inc. | sunlife.com                                           42

             Annual Information Form 2023
final rule amendments published by the Canadian Securities Administrators and the Canadian Council of Insurance Regulators in April 2023, and coming into effect on January 1, 2026 to enhance total cost reporting for investment funds and segregated funds and the implementation of the Financial Services Regulatory Authority of Ontario. The U.S. Securities and Exchange Commission published, among other new requirements, a significant expansion of the rules applicable to private funds prohibiting private fund advisers from providing certain types of preferential treatment to investors.
•In June 2020, China passed the Hong Kong National Security Law under which law enforcement authorities have extensive powers. In July 2020, then-U.S. President Trump signed into law the Hong Kong Autonomy Act (the "Act"), and issued an Executive Order providing authority to impose primary sanctions against entities and individuals determined to have materially contributed to the undermining of Hong Kong’s autonomy. The Act also provides authority to impose secondary sanctions against non-U.S. financial institutions determined to have conducted a significant transaction for any individual or entity subject to primary sanctions under the Act. In June 2021, China enacted the Law of the People’s Republic of China on Countering Foreign Sanctions, which authorizes the State Council to impose countermeasures in response to sanctions imposed by foreign governments on Chinese companies and individuals. The U.S. and China have applied a number of targeted sanctions and export control restrictions against the other's respective interests n recent years. There may be heightened risks and uncertainties to our business in Hong Kong as a result of these developments.
•Regulators are increasing their focus on data, technology and cybersecurity. New laws, regulations, guidelines, directives and expectations have begun to emerge that will require the Company to continue to enhance its technology and information security programs, upgrade its third-party risk management and data governance programs, increase regulatory reporting obligations and have an impact on the costs and resources associated with the Company’s data technology and information security activities.
•IBORs, including US dollar LIBOR and CDOR, measure the average cost that banks pay to borrow from each other on an unsecured short-term basis. They have historically been used as a benchmark or reference rate for various types of financial products and contracts. All LIBOR settings were either discontinued or declared non-representative on or before June 30, 2023, and CDOR will be discontinued after June 28, 2024. Uncertainty relating to the transition to alternative reference rates and other factors related to reform may adversely affect our operations and cash flows and the value of and return on our Investments that are IBOR-based.
•Regulators in the various jurisdictions in which we operate have increased their focus on ESG matters, including the impact of climate change, and some regulators have taken steps towards introducing or have already introduced rules to address risks and disclosures around these matters. In Canada, OSFI issued Guideline B-15 on Climate Risk Management ("Guideline B-15") in March 2023, which sets out OSFI’s expectations related to the management and disclosure of climate-related risks by FRFIs. For certain FRFIs including Sun Life, Guideline B-15 will become effective fiscal year-end 2024, with applicable disclosures required to be published no later than 180 days after fiscal year-end. Guideline B-15 is expected to be updated iteratively. In 2021, the Canadian Securities Administrators published National Instrument 51-107 on disclosure of climate-related matters, which could introduce climate-related disclosure requirements for Canadian reporting issuers. In addition, in 2022, the CSA published guidance for investment funds relating to ESG disclosure. In the U.S., state governments and regulators have increased their focus on the ESG practices of financial institutions and asset managers, particularly with respect to climate risk, including conflicting state level considerations that reflect the political polarization surrounding ESG in the U.S. Additionally, the SEC has proposed rule changes which would require many registrants to include certain climate-related disclosures in their regulatory filings. Internationally, in 2023 the International Sustainability Standards Board issued IFRS S1 and S2 disclosure standards for general sustainability-related disclosures and climate-related disclosures, respectively, which could be incorporated into Guideline B-15 and other forthcoming disclosure requirements. In addition, the broad-reaching EU Corporate Sustainability Reporting Directive came into effect, which mandates comprehensive reporting under the European Sustainability Reporting Standards from many non-EU headquartered companies. Potential divergence in expectations among regulators, as well as the pace of regulatory change in the area of climate change, could lead to operational risks. We continue to monitor our risk management practices and disclosures as new regulations and standards are implemented and as the situation continues to evolve. We are also monitoring trends in climate- and broader sustainability-related litigation, including "greenwashing" cases involving allegations of exaggerated or misleading sustainability claims.

See the heading Regulatory Matters above for a description of our regulatory environment in Canada, the U.S., Asia and Bermuda and other examples of changes in regulation that may affect our business and operations.
Environmental and Social Risk
Our financial performance, operations, and reputation may be adversely affected if we do not adequately prepare for the direct or indirect impacts of environmental and social risks. Environmental risk includes environmental damage on properties owned or managed by us and climate change related physical and transition risks. These events and developments may include increased frequency and severity of natural or human-made environmental disasters, longer-term shifts in climate patterns, emerging regulatory and public policy developments, and their impacts on our operations, invested assets, suppliers, Clients and reputation. External factors such as stakeholder expectations around environmental performance, resource constraints and costs associated with adaptation are also potential sources of environmental risk. Risks that affect our Clients and our suppliers could have a negative impact on our operations and performance. Social risk includes but is not limited to
Sun Life Financial Inc. | sunlife.com                                           43

             Annual Information Form 2023
public health issues and issues of inequality. These risks are considered in our key risk assessments. An environmental issue on a property owned or operated by us could have financial or reputational impacts.

A transition to a lower carbon economy could affect asset values. Among other impacts, portfolio investments in coal, conventional oil and oil sands producers, utilities and related fossil fuel industries, railways and pipelines, as well as markets that depend on these industries, may be subject to additional financial risk as a result of changes in regulation, cost of capital, consumer preferences and competition from renewable energy companies. This may lead to lower overall profitability and/or stranded assets (assets for which the investment costs cannot be recovered as intended).

Physical climate impacts could affect investments in real assets such as real estate, commercial mortgages, and infrastructure, as well as our own operations, and operations and revenues of our Clients and businesses across our portfolios. Risks may result from increased severity and frequency of extreme weather events and from longer-term shifts in climate patterns.

If our Clients, shareholder groups, or other key stakeholders deem that our environmental, social, climate change or other sustainability-related practices are inadequate, our reputation and operations could be negatively affected. Failure to comply with an existing or potential Client's policies in these areas could disqualify us from bidding on, or earning business opportunities, or retaining existing business. We may also experience reduced access to capital markets if sustainability indices and/or investors find that our practices fall short of their criteria, which in turn could result in being removed from one or more of these indices or as an appropriate investment by investors.

As an owner/lessor of, investor in real estate, we may be impacted where environmental events damage or disrupt our underlying properties. Our businesses and the properties underlying our investments are subject to environmental laws and regulations in all key jurisdictions where we carry on business or hold investments. Consequently, we may experience environmental impacts or liabilities that could adversely affect the value of those businesses and properties, their ability to generate income, and costs related to any required compliance requirements or remediation. Through other invested assets, such as loans, bonds or equity investments, we could be subject to these impacts and negative consequences from environmental issues arising at the level of the issuer and/or specific asset. Our reputation and operations may be adversely affected if we or our tenants, borrowers, or other associated parties violate environmental regulations or best practices.

As noted above under Insurance Risk - Mortality and Morbidity Risk, environmental risks, including climate change risks have implications in areas such as catastrophic risk and the concentration risk presented by natural and human-made environmental disasters, which could impact our mortality and morbidity experience and our pricing and modeling assumptions as these events increase. For example, in our group benefits businesses, a localized event that affects the workplace of one or more of our Clients could cause a significant loss related to a concentration of claims under group policies.

In addition to the impacts noted above, failure to adequately prepare for the potential impacts of environmental risks, including those associated with climate change, may have other direct and indirect negative impacts. These may include business losses or disruption, including a shift in Client preferences or demands, resulting from:
•extreme weather conditions or other environmental disasters,
•longer-term shifts and impacts related to warming temperatures, the availability of food and water and other ongoing climate change impacts,
•wider and/or more rapid transmission of new and existing diseases through pandemics or otherwise, and
•other unforeseen human consequences.

Significant environmental changes and disasters may also reduce the overall level of economic activity in affected areas which could hurt our businesses, the value of our investments, our ability to offer products and services, or service our existing Clients.

These risks could also harm the financial condition of our reinsurers and insurers of property which we own, lease, have invested in or manage which may increase the risk of default on recoveries from these reinsurers and insurers, may increase the cost of reinsuring our business or the cost of insurance, and may result in reinsurance or insurance coverage being unavailable.

Operational Risk
Operational risk is the risk of loss (financial and non-financial) resulting from inadequate or failed internal processes, people and systems or from external events. Operational risk is present in all of our business activities and encompasses a broad range of risks as described below. Operational risk is embedded in the practices utilized to manage other risks and, therefore, if not managed effectively, operational risk can impact our ability to manage other key risks.
Sun Life Financial Inc. | sunlife.com                                           44

Information Security and Privacy Risks
Information and technology are used in almost all aspects of our business and operations. As part of our Client strategy, we continue to enhance the digital side of our business to support and enable new business models and processes, that are more personal, proactive and predictive.

Our business and the successful implementation of our digital strategy are dependent on various factors including maintaining a secure environment for our Clients, employees and other parties' information. This requires the effective and secure use, management and oversight of information and physical assets. We engage with various stakeholders and leverage emerging technologies, including digital, mobile applications, cloud computing, artificial intelligence and robotic process automation. These technologies are used to collect, process and maintain information relating to business transactions and financial reporting, as well as the personal information of our Clients and employees. We also obtain services from a wide range of third-party service providers and have outsourced some business and information technology functions in various jurisdictions.

There continues to be an increasing number of information security compromises and privacy breaches across industry sectors, governments and individuals. The increasing scope and complexity of malicious activity poses a significant risk to our systems and these risks may be exacerbated by the breadth of our operations, our geographic footprint and the complexity of our technology systems. A serious security or privacy breach of either an internal or third-party service provider’s computer system that contains sensitive business, Client and/or employee information may result in business interruption, theft or misuse of confidential information, regulatory penalties and scrutiny, litigation, reputational damage and may have an adverse impact on current and future business opportunities with our Clients, employees and business relationships. We continue to actively monitor for increases in malicious activity due to escalating geopolitical tensions across the globe.

In particular, privacy breaches could occur and may result in unauthorized access and disclosure or use of personal information. Many jurisdictions in which we do business are developing and implementing reporting requirements relating to cybersecurity and more stringent consumer privacy legislation, many with greater enforcement powers for regulators and higher potential fines and penalties.

We have established security controls and processes that are intended to protect information and computer systems including information security risk assessments and privacy impact assessments. Notwithstanding these measures, the threat environment is rapidly and constantly changing, and there remains a possibility that our processes and controls could be unsuccessful in detecting or preventing a security breach. We remain vulnerable, and work with third parties who may also be vulnerable, to computer viruses and other types of malicious software, cyber-attacks and hacking attempts from unauthorized persons, the physical theft of computer systems, internal programming or human errors, fraud, or other disruptive problems or events. There is also a risk that certain internal controls fail, which could also exacerbate the consequences from such events.
Human Resources Risk
Our ability to achieve business objectives can be adversely affected if we are unable to attract, retain or effectively deploy resources with the in-depth knowledge and necessary skills required, or are unable to design compensation and talent programs that effectively drive employee behaviour and shape corporate culture. Failure to manage Human Resources risk can also lead to direct financial and reputational loss including losses arising from activity that is inconsistent with Human Rights or employment laws or health and safety regulations.
Regulatory Compliance, Legal and Conduct Risk
We are subject to extensive regulatory oversight by financial services regulators in the jurisdictions in which we conduct business. Failure to comply with applicable laws or to conduct our business consistent with changing regulatory or public expectations could adversely impact our reputation and may lead to regulatory investigations, examinations, proceedings, settlements, penalties, fines, restrictions on our business, litigation or an inability to carry out our business strategy.

As a business with external Clients and stakeholders, we face many operational risks, including reputational, legal, fraud, third-party, and privacy. Examples of how these operational risks may affect our business are outlined below:
•Reputational Risk: any action, or harmful result from an action, that becomes public information may result in a loss of public trust and confidence, resulting in Clients not buying, or redeeming, our products.
•Legal Risk: during the normal course of operating our business, we are subject to the risk of adverse litigation including class action lawsuits.
•Fraud Risk: both internal and external fraud are possibilities within our business, such as opening policies under other people’s names. Such actions could result in reputational damage and lawsuits.
•Third-party Risk: by relying on third parties to conduct parts of our business, we are entrusting them to have controls in place to protect our Clients and stakeholders; however, controls can fail, which could expose us to privacy risk, legal, and information security risk.
•Privacy Risk: any leakage of personal information could have ramifications for our business and may lead to lawsuits and reputational damage.

Sun Life Financial Inc. | sunlife.com                                           45

             Annual Information Form 2023
As an international organization, we are subject to anti-bribery and anti-corruption laws, including the U.S. Foreign Corrupt Practices Act, the Canadian Corruption of Foreign Public Officials Act, and the UK Bribery Act, each of which include significant civil and criminal penalties if breached. Our policies, including our Code of Conduct, require strict adherence to these laws. We, or our joint ventures, Distributors or other third-parties acting on our behalf, may from time to time interact with government officials, which presents a heightened risk of censure under anti-bribery and anti-corruption laws if our or our business partners' due diligence or other procedures when interacting with government officials are deemed inadequate.

Financial services regulators and other government agencies in jurisdictions we operate regularly make inquiries, conduct investigations and administer examinations with respect to compliance with applicable laws and regulations. As well, regulators and governmental authorities, industry groups and rating agencies have developed initiatives regarding market conduct. Financial services regulators and other governmental authorities in many of the countries in which we operate have raised issues and commenced regulatory inquiries, investigations and proceedings with respect to current and past business practices in the financial services industry and have given greater emphasis to the investigation of those practices. Current and future regulatory investigations, examinations, proceedings, and civil actions arising out of such matters could adversely affect our reputation, and may result in settlements, penalties, fines, restrictions on our business, litigation or an inability to carry out our business strategy or may cause us to make changes to our business and compliance practices, policies and procedures, which in turn could impact our profitability and future financial results and increase our litigation risk.

Under the Insurance Act and the Supervisory Information (Insurance) Regulations (Canada) and pursuant to similar restrictions in other jurisdictions, we are prohibited from directly or indirectly disclosing any supervisory information relating to SLF Inc., Sun Life Assurance and their affiliates.
Information Technology Risk
The use of technology and computer systems is essential in supporting and maintaining business operations. We use technology to support virtually all aspects of our business and operations. The rapidly changing business environment increases the risk of our technology strategy not being agile enough to adapt to new business demands in a timely manner leading to financial losses, increased costs and the inability to meet Client needs.

Initiatives supporting our business strategy rely on developing innovative information technology solutions and upgrading our existing systems on a timely basis to meet business needs. Although every reasonable precaution is taken to ensure information technology systems remain available, stable and current, it is not possible to fully eliminate all risk. Some changes and upgrades are extremely complex and there is a chance that an undetected technical flaw may exist, which, when implemented, stops or disrupts critical information technology systems or business applications.
Third-Party Risk
We engage in a variety of third-party relationships, including with distributors, independent contractors, outsourcing service providers and suppliers. Our profitability or reputation could be impacted if these third parties are unable to meet their ongoing service commitments or fail to perform to expected standards.

An interruption in our relationship with certain third parties or other parties engaged by such third parties, the impairment of their reputation or creditworthiness, their failure to provide contracted services in the manner agreed or in accordance with applicable laws and regulations could materially and adversely affect our business objectives or expose us to regulatory fines and/or reputational harm. Even with contingency plans developed for our material third party arrangements, there can be no assurance that we would be able to transition to alternate sources for these arrangements in a timely manner, at reasonable cost, or with minimal disruption to our stakeholders.
Business Disruption Risk
To conduct operations, our businesses are dependent on the availability of trained employees, physical locations and access to technology. A significant business disruption to our operations can result if one or more of these key elements are negatively impacted.

Although we have implemented and periodically test our business continuity, crisis management and disaster recovery plans, a sustained failure of one or more of our key business processes or systems could materially and adversely impact our business, operations and employees. These failures can result from disruption of our processes and systems due to utility outages, fires, floods, severe storms, cyber-attacks, terrorism and other human-made attacks, natural disasters and other events. We have experienced increased incidences and impacts of disruption due to weather events such as tropical storms and flooding in the geographies in which we operate, as well as earthquakes and pandemic risks. In addition to these key business processes and system disruptions, these unanticipated events, including disease pandemics, can also negatively affect staff, preventing them from working or from operating business processes. Business disruptions can also occur due to changes in environmental risk and related impacts have been highlighted above under the heading Environmental and Social Risk. Also, because some of our business processes are performed by third parties and some of our systems interface with or are dependent on third-party systems, we could experience service interruptions if these third-party operations or systems fail.
Sun Life Financial Inc. | sunlife.com                                           46

             Annual Information Form 2023
Model Risk
We use complex models to support many business functions including product development and pricing, capital management, valuation, financial reporting, planning, hedging, asset-liability management, risk management and advanced analytics (such as artificial intelligence, predictive modeling and decision making algorithms). Model risk is the risk of loss, either in the form of financial loss, inappropriate or poor business decisions, damage to reputation, or other adverse impact, arising from inaccurate model outputs or incorrect use or interpretation of model outputs.

Model risk can arise from many sources including inappropriate methodologies, assumptions or parameters, incorrect use of source data, inaccurate or untimely source data, incorrect application or operator errors, increasing product complexity and regulatory expectations. If the models' methodologies and assumptions are not appropriately set or well controlled, or data or implementation errors occur in the models, this could result in a negative impact on our results and financial position.

Many of our methods and models for managing risk and exposures are based upon the use of observed historical precedents for financial market behaviour, credit experience and insurance risks. As a result, these methods may not fully predict future risk exposures, which can be significantly greater than our historical measures indicate. Other risk management methods depend upon the evaluation of information regarding markets, Clients, catastrophic occurrence or other matters that are publicly available or otherwise accessible to us. However, this information may not always be accurate, complete, up-to-date, properly evaluated or necessarily indicative of ultimate realized experience. As we review and update our models, changes might be made to valuation methods and assumptions, which may impact our results.
Information Management Risk
As an international provider of financial services, we deal with extensive information across a number of countries. Information management risk is the a) inability to capture, manage, retain and appropriately dispose of business records, b) the inability to provide data that is valid, complete, accurate, consistent, unique, or timely to support business decisions, and c) the inability to manage data location and cross-border access appropriately. Failure to manage these risks could have financial or reputational impacts, and may lead to regulatory proceedings, penalties and litigation. To manage and monitor information management risk, we have a data governance framework, which includes a records management program, data quality best practices, and data residency controls.

We continue to evolve our risk management best practices to manage risks associated with Generative-AI as we identify use cases and run experiments designed to identify opportunities.

Additional information on operational risk can be found in the Risk Factors section of this AIF.

Liquidity Risk
Liquidity risk is the possibility that we will not be able to fund all cash outflow commitments and collateral requirements as they fall due. This includes the risk of being forced to sell assets at depressed prices resulting in realized losses on sale. This risk also includes restrictions on our ability to efficiently allocate capital among our subsidiaries due to various market and regulatory constraints on the movement of funds. Our funding obligations arise in connection with the payment of policyholder benefits, expenses, reinsurance settlements, asset purchases, investment commitments, interest on debt, and dividends on common and preferred shares. Sources of available cash flow include general fund premiums and deposits, investment related inflows (such as maturities, principal repayments, investment income and proceeds of asset sales), proceeds generated from financing activities, and dividends and interest payments from subsidiaries. We have various financing transactions and derivative contracts under which we may be required to pledge collateral or to make payments to our counterparties for the decline in market value of specified assets. The amount of collateral or payments required may increase under certain circumstances (such as changes to interest rates, credit spreads, equity markets or foreign exchange rates), which could adversely affect our liquidity.

Under stress conditions, increases in funding obligations can occur in conjunction with reductions in cost effective sources of available cash inflow. In particular, adverse stress scenarios could involve increases in policyholder cash surrenders and terminations and decreases in the amounts of premiums and deposits being generated by existing and new Clients. Adverse capital market conditions may also be associated with a reduction in available market liquidity and clearing prices for expected asset sales, and reductions in the level of cash inflows (dividends, interest payments and expected maturities) on continuing portfolio investments. These developments could have an adverse effect on our financial position and results of operations.

We engage in various transactions including repurchase agreements and other capital markets transactions to meet short-term cash requirements. The cost and our ability to execute these transactions may be negatively impacted by illiquid or volatile markets. Disruption in the financial markets may limit our access to capital in the event we are required to seek additional liquidity to operate our businesses. This will result in increased costs to raise capital coupled with less desirable terms or maturities which would decrease future profitability and financial flexibility.

SLF Inc. is a holding company for its insurance, wealth and asset management subsidiaries and does not have significant operations of its own. Dividends and interest payments from its subsidiaries are its principal sources of cash. If the cash
Sun Life Financial Inc. | sunlife.com                                           47

             Annual Information Form 2023
received from its subsidiaries is insufficient, then it may be required to raise debt or equity externally or sell some of its assets. We are subject to various regulations in the jurisdictions in which we operate. The ability of SLF Inc.'s subsidiaries to pay dividends and transfer funds is regulated in certain jurisdictions and may require local regulatory approvals and the satisfaction of specific conditions in certain circumstances.

In addition, rating agencies publish credit ratings of securities issued by SLF Inc. and its subsidiaries, which have an impact on the interest rates paid by those companies on borrowed funds. A material downgrade in the issuer credit ratings could limit our access to capital or increase the cost of borrowing and may have an adverse effect on our financial condition.

We have established financing arrangements that support NAIC statutory reserves for universal life policies issued by Sun Life Assurance in the U.S. Our ability to support these reserves with these financing structures can be negatively impacted by market conditions and regulatory changes. Further, these financings, in all or in part, are treated as operating leverage by the rating agencies. If, due to a change in rating agency methodology or position, the rating agencies cease to treat these financings as operating leverage, without providing any grandfathering provisions, there may be an adverse impact on our credit and financial strength ratings.

Other Risks
Risks relating to Pandemics
Pandemics, epidemics or outbreaks of an infectious disease could have an adverse impact on our results, business, financial condition or liquidity, and could result in changes to the way we operate. Pandemics and measures imposed by governments around the world could disrupt the global economy, financial markets, supply chains, business activity and productivity. The potential worsening of the economic and market conditions caused by pandemics, and impact on Clients, industries and individual countries could have a material adverse effect on our businesses including sales, fee income, investment performance, expenses, results of operations, corporate reputation and financial condition. Sustained adverse effects could negatively impact profitability and also make it difficult for us to access capital markets, could impact our liquidity and capital position, or may result in downgrades in our credit ratings. These actions may also have the effect of heightening many of the other risks described in the section entitled "Risk Factors" in this document and "K - Risk Management" in our 2023 MD&A. This includes, but is not limited to:
•Market risks, such as equity, interest rates and spread, real estate, and foreign currency risks, including impact on fee income;
•Insurance risk, including higher than expected mortality and, morbidity claims and adverse policyholder behaviour including but not limited to higher than expected policy lapses, withdrawals, and surrenders;
•Credit risk, including defaults, impairments and downgrades;
•Business and strategic risk including economic and geopolitical risk, business strategy implementation risk, distribution risk, expense risk, changes in Client behaviour, sales, investment performance, and changes in legal and regulatory environment;
•Operational risk, including information security and privacy risk, human resources risks, regulatory compliance, legal and conduct risk, information technology risk, processing risk, third-party risk, and business disruption risk, and change management risk with the need to quickly implement and execute new programs and procedures to support Clients, advisors, employees, products, and services; and
•Liquidity risk including collateral, and payment deferrals on invested assets or policyholder insurance premium impacts.

International Operations
The future success of our businesses in our international operations depends in large part on our ability to grow and compete in the markets where we operate. Challenges in these markets pose strategic and execution risk including our ability to attract and retain qualified employees and executives with local experience and critical skills, geopolitical, legal, economic, competition or other risks, risks associated with joint venture operations, developing and executing our risk management practices, and our ability to attract, retain, expand and diversify distribution channels.

If we are unable to attract, retain and engage qualified employees and executives with relevant experience and critical business skills, our ability to grow our business in our international operations as quickly as planned may be limited. Competition for qualified employees and distribution partners in our international operations, in particular the Asian markets, continues to be strong and could adversely impact our ability to attract and retain talent.

Our international operations may face geopolitical, legal and regulatory, economic, competitive, operational or other risks that we may not face in our domestic operations. Examples of this type of risk are the risk of changes in regulation, geopolitical risks due to changes in government, discriminatory regulation, political instability, nationalization or expropriation of assets, changes to the maximum level of non-domestic ownership, price controls and exchange controls or other restrictions that could prevent us from transferring funds from these operations out of the countries in which they operate or converting local currencies we hold into Canadian dollars or other currencies.

             Annual Information Form 2023
Capital markets in certain international markets may not have the same depth, liquidity or range of investment options generally available in other markets in which we operate. In particular, the more limited availability of long-duration assets exposes our Asian operations to higher asset-liability management costs and potential risk.

We have entered into joint venture arrangements in certain markets in Asia, where we may have a lesser degree of control over these businesses that may expose us to additional operational, financial, compliance and legal risks. We may be dependent on our joint venture counterparty for capital, product distribution, local market knowledge, or other resources. Our ability to exercise management control or influence over these joint ventures and the success of our investments in them will depend on the cooperation between the joint venture participants and the terms of the joint venture agreements, which allocate control among the joint venture participants. If we are unable to effectively manage these joint ventures, or any joint venture counterparty fails to meet its obligations under the joint venture arrangement, encounters financial difficulty, elects to alter, modify or terminate the relationship, or a joint venture does not comply with local legislation or regulations, we may be unable to achieve our objectives and our results of operations and brand may be negatively impacted.
Capital Adequacy
Capital adequacy risk is the risk that our capital position is not or will not be sufficient to withstand adverse economic conditions, to maintain our financial strength, to allow us and our subsidiaries to support ongoing operations and to take advantage of opportunities for expansion, and to support the risk taking activity in pursuit of our business objectives.

The strength of our capital position depends in part upon the level of and changes in interest rates and equity prices, credit experience, mortality and morbidity experience, currency rate fluctuations and our overall profitability.

Various factors such as declining equity markets, downgrades in ratings, changes in interest rates, changes in credit spreads on corporate bonds and asset backed securities, lower earnings and inability to access capital markets on a timely basis may negatively impact our capital ratios, and may impair our financial position and our ability to execute our business strategies and plans. In addition, regulatory changes being considered by other regulators world-wide may adversely impact the capital of SLF Inc. and its insurance subsidiaries. These factors may impair our financial position and our ability to execute our business strategy.
Credit and Financial Strength Ratings
Financial strength ratings represent the opinions of rating agencies regarding the financial ability of an insurance company to meet its obligations under insurance policies. Credit ratings indicate the opinions of rating agencies regarding an issuer's ability to meet the terms of debt, preferred share and Tier 1 hybrid capital obligations in a timely manner, and are important factors in a company’s overall funding profile and ability to access external capital. A downgrade by a rating agency in the credit ratings of securities issued by SLF Inc. and its subsidiaries or the financial strength ratings of SLF Inc.'s insurance company subsidiaries could adversely affect our financial condition and results of operations.

The financial strength rating of an insurance company is a key competitive factor in marketing its products and in attracting and retaining agents and distributors. If our credit or financial strength ratings are downgraded, our financial condition, competitive position and results of operations could be negatively impacted in many ways, including:
•Reducing new sales of insurance products, annuities and investment products;
•Requiring us to reduce prices for products and services to remain competitive;
•Higher level of surrenders and withdrawals;
•Higher reinsurance costs;
•Increasing our cost of capital and limiting our access to the capital markets, thus reducing our financial flexibility;
•Reducing our ability to enter into normal course derivative or hedging transactions and increasing the costs associated with such transactions; and
•Adversely affecting our relationships with our advisors and third-party distributors of our products.

In addition, downgrades in our credit or financial strength ratings below thresholds specified in certain of our derivative agreements, reinsurance agreements and other agreements could result in the counterparties to those agreements having the right to terminate those agreements or to require that we provide support for those agreements in the form of collateral or letters of credit.

Changes in methodologies and criteria used by rating agencies could also result in downgrades that do not reflect changes in the general economic conditions or our financial condition.

Additional information concerning our ratings is provided in this AIF under the heading Security Ratings and in our 2023 MD&A under the heading Financial Strength.

             Annual Information Form 2023
Tax Matters
The validity and measurement of tax benefits associated with various tax positions taken or expected to be taken in our tax filings are a matter of tax law and are subject to interpretation. Tax laws are complex and their interpretation requires significant judgment. The provision for income taxes reflects management’s interpretation of the relevant tax laws and its best estimate of income tax implications of the transactions and events during the period. There can be a risk that tax authorities could differ in their interpretation of the relevant laws and could assert that tax positions taken by the company give rise to a need for reassessment, including reassessment under specific or general anti-avoidance rules or transfer pricing provisions.

The assessment of additional taxes, interest and penalties or damage to the Company’s reputation could be materially adverse to our future results of operations and financial position.

Under the liability method of accounting for income taxes, deferred tax assets are recognized for the carryforward of unused tax losses and tax credits, as well as amounts that have already been recorded in the financial statements, but will not result in deductible amounts in determining taxable income until future periods. Deferred tax assets are recognized only to the extent of the probability that taxable profit will be available against which the future tax deductions and unused tax losses can be utilized.

At the end of each reporting period, we must assess the value of our deferred tax assets. The determination of our deferred tax assets is dependent upon projections of future taxable profits. Our projections require significant judgments and estimates about future events, including global economic conditions and the future profitability of our businesses. If the profitability of our businesses is lower than our projections or if our outlook diminishes significantly, we may be required to reduce the value of our deferred tax assets. Any change to our deferred tax assets could have a material adverse impact on our future results of operations and financial position.

We are also subject to changing income tax regulations. We currently have an effective income tax rate that is lower than the Canadian statutory income tax rate for corporations. The Company reflects favourable tax impacts in its financial statements from certain tax benefits, including but not limited to tax-exempt investment income, dividends received deductions, tax credits (from certain investments or from taxes paid on foreign source income), and favourable tax rates in certain jurisdictions in which we operate. In addition, many of our life insurance products benefit Clients with preferred tax treatment under various tax regimes. For example life insurance policies and annuity contracts in the U.S. and Canada allow for the deferral or elimination of taxation on earnings (inside buildup) accrued under the policy. There is a risk that tax legislation, administrative guidance or legislative developments could lessen or eliminate some of the benefits currently available to the Company or its policyholders. This risk could result in lower product sales or increased lapses of policies, and could have a material adverse effect on our future results of operations and financial position.

From time to time, governments in countries in which we operate enact changes to statutory corporate income tax rates. A change in income tax rate requires us to review and re-measure our deferred tax assets and liabilities as of the date of substantive enactment. As of December 31, 2023, the Company reported a $3,597 million net deferred tax asset in its Consolidated Statements of Financial Position, primarily in Canada. Any future tax rate reductions in jurisdictions where we carry a net deferred tax asset could result in a reduction in the carrying value of the deferred tax asset and a corresponding income tax expense at the time of substantive enactment of a rate reduction.

On August 4, 2023, the Canadian Department of Finance released draft legislation to implement certain previously announced measures, including application rules for a 15% global minimum tax under the Organisation for Economic Co-Operation and Development’s (OECD) two-pillar plan (Pillar Two), which is to be applied on a jurisdiction-by-jurisdiction basis. The global minimum tax rules will apply to Sun Life effective January 1, 2024, however the timing of the substantive enactment of these rules is uncertain. Under the legislation, Sun Life is liable to pay a top-up tax for the difference between their effective tax rate per jurisdiction and the 15% minimum rate.

The Pillar Two legislation framework issued by the OECD requires a top-up tax amount determined on a jurisdiction-by-jurisdiction basis, but the tax may be paid or payable to the jurisdiction where the profits are earned, through a domestic top-up tax or in another jurisdiction, through the income inclusion rule or the undertaxed profits rule. In addition to the Pillar Two rules, certain jurisdictions in which Sun Life operates have or are expected to introduce a corporate income tax, for example, Bermuda has enacted corporate income tax legislation that will be effective January 1, 2025, and is expected to be considered a covered tax for purposes of the Pillar Two rules. The jurisdictions in which Sun Life operates and top-up tax may be applicable are Bermuda, Hong Kong, and Ireland, and it is anticipated that the Pillar Two top-up tax may be payable in these jurisdictions (if a domestic top-up tax is adopted) and/or in Canada (the location of the ultimate parent entity).
