•Net income available to Arch common shareholders of $1.3 billion, or $3.30 per share, representing a 26.3% annualized net income return on average common equity, compared to net income available to Arch common shareholders of $661 million, or $1.75 per share, for the 2023 second quarter.
•After-tax operating income available to Arch common shareholders(1) of $981 million, or $2.57 per share, representing a 20.5% annualized operating return on average common equity(1), compared to $726 million, or $1.92 per share, for the 2023 second quarter.
•Pre-tax current accident year catastrophic losses for the Company’s insurance and reinsurance segments, net of reinsurance and reinstatement premiums, of $196 million.

For additional details regarding the Company’s operating segments, please refer to the Company’s Financial Supplement dated June 30, 2024. The Company’s segment information includes the use of underwriting income (loss) and a combined ratio excluding catastrophic activity and prior year development (see ‘Comments on Non-GAAP Financial Measures’ for further details).

(U.S. Dollars in millions) 2024 2023 % Change
Gross premiums written $ 2,102  $ 1,955  7.5 
Net premiums written 1,558  1,454  7.2

Net (favorable) adverse development in prior year loss reserves, net of related adjustments (0.2) % (0.5) % 0.3 
Combined ratio excluding catastrophic activity and prior year development 90.8  % 89.8  % 1.0 
Gross premiums written by the insurance segment in the 2024 second quarter were 7.5% higher than in the 2023 second quarter, while net premiums written were 7.2% higher than in the 2023 second quarter. Growth in net premiums written reflected increases in most lines of business, due in part to new business opportunities and rate changes. Net premiums earned in the 2024 second quarter were 11.3% higher than in the 2023 second quarter, and reflect changes in net premiums written over the previous five quarters.
The 2024 second quarter loss ratio reflected 2.0 points of current year catastrophic activity, spread across a series of global events, compared to 2.7 points of catastrophic activity in the 2023 second quarter. Estimated net favorable development of prior year loss reserves, before related adjustments, reduced the loss ratio by 0.3 points in the 2024 second quarter, compared to 0.9 points in the 2023 second quarter.
The underwriting expense ratio was 35.3% in the 2024 second quarter, compared to 34.6% in the 2023 second quarter, with the increase reflecting a higher level of aggregate operating expenses.

Reinsurance Segment
Three Months Ended June 30,
(U.S. Dollars in millions) 2024 2023 % Change
Gross premiums written $ 2,941  $ 2,544  15.6 
Net premiums written 1,947  1,709  13.9

Underwriting expense ratio 23.0  % 26.6  % (3.6)
Combined ratio 79.5  % 81.9  % (2.4)
Catastrophic activity and prior year development:
Current accident year catastrophic events, net of reinsurance and reinstatement premiums 9.4  % 6.3  % 3.1 
Net (favorable) adverse development in prior year loss reserves, net of related adjustments (1.8) % (1.8) % — 
Combined ratio excluding catastrophic activity and prior year development 71.9  % 77.4  % (5.5)
Gross premiums written by the reinsurance segment in the 2024 second quarter were 15.6% higher than in the 2023 second quarter, while net premiums written were 13.9% higher than in the 2023 second quarter. The growth in net premiums written reflected increases in all lines of business, due in part to rate increases, new business opportunities and growth in existing accounts. Net premiums earned in the 2024 second quarter were 32.5% higher than in the 2023 second quarter, and reflect changes in net premiums written over the previous five quarters.
The 2024 second quarter loss ratio reflected 10.0 points of current year catastrophic activity, spread across a series of global events, compared to 6.7 points of catastrophic activity in the 2023 second quarter. Estimated net favorable development of prior year loss reserves, before related adjustments, reduced the loss ratio by 1.9 points in the 2024 second quarter, compared to 2.2 points in the 2023 second quarter. The balance of the change in the loss ratio resulted, in part, from the impact of rate increases, lower level of attritional losses and changes in the mix of business.
The underwriting expense ratio was 23.0% in the 2024 second quarter, compared to 26.6% in the 2023 second quarter, with the decrease primarily due to a lower acquisition expense ratio and the beneficial effect of growth in net premiums earned.

Mortgage Segment
Three Months Ended June 30,
(U.S. Dollars in millions) 2024 2023 % Change
Gross premiums written $ 340  $ 347  (2.0)
Net premiums written 276  265  4.2 
Net premiums earned 307  294  4.4 
Other underwriting income (33.3)
Underwriting income $ 287  $ 253  13.4

Underwriting expense ratio 16.0  % 19.5  % (3.5)
Combined ratio 7.4  % 15.0  % (7.6)
Prior year development:
Net (favorable) adverse development in prior year loss reserves, net of related adjustments (29.0) % (28.7) % (0.3)
Combined ratio excluding prior year development 36.4  % 43.7  % (7.3)
Gross premiums written by the mortgage segment in the 2024 second quarter were 2.0% lower than in the 2023 second quarter, while net premiums written were 4.2% higher. The increase in net premiums written and earned in the 2024 second quarter primarily reflected a lower level of Bellemeade premiums ceded, due in part to the termination of certain Bellemeade agreements in the 2023 fourth quarter.
Estimated net favorable development of prior year loss reserves, before related adjustments, decreased the loss ratio by 26.9 points, compared to 27.2 points in the 2023 second quarter. Such amounts were primarily related to better than expected cure rates. The 2024 second quarter loss ratio, excluding net favorable development, was down compared to the 2023 second quarter, reflecting lower estimated claim rates partially offset by slightly higher new delinquencies.
The underwriting expense ratio was 16.0% in the 2024 second quarter, compared to 19.5% in the 2023 second quarter. The decrease was primarily due to higher level of ceding and profit commissions on U.S. primary business, along with a higher level of net premiums earned.

Corporate
The Company’s results include net investment income, net realized gains or losses (which includes realized and unrealized changes in the fair value of equity securities and assets accounted for using the fair value option, realized and unrealized gains and losses on derivative instruments, changes in the allowance for credit losses on financial assets and gains and losses realized from the acquisition or disposition of subsidiaries), equity in net income or loss of investment funds accounted for using the equity method, other income (loss), corporate expenses, transaction costs and other, amortization of intangible assets, interest expense, net foreign exchange gains or losses, income tax items, income or loss from operating affiliates and items related to the Company’s non-cumulative preferred shares.
Investment returns were as follows:
(U.S. Dollars in millions, except per share data) Three Months Ended
June 30, March 31, June 30,
2024 2024 2023
Pre-tax net investment income $ 364  $ 327  $ 242 
Per share $ 0.95  $ 0.86  $ 0.64 
Equity in net income (loss) of investment funds accounted for using the equity method $ 167  $ 99  $ 69 
Per share $ 0.44  $ 0.26  $ 0.18 
Pre-tax investment income yield, at amortized cost (1) 4.39  % 4.14  % 3.50  %
Total return on investments (2) 1.33  % 0.80  % 0.56  %
(1)    Presented on an annualized basis and excluding the impact of investments for which returns are not included within investment income, such as investments accounted for using the equity method and certain equities.
(2)    See ‘Comments on Non-GAAP Financial Measures’ for further details.
The growth in net investment income in the 2024 second quarter primarily reflected the effects of sustained higher interest rates available in the market, along with growth in invested assets due in part to strong operating cash flows. Net realized gains were $122 million for the 2024 second quarter, compared to net realized losses of $123 million in the 2023 second quarter, and reflected sales of investments as well as the impact of financial market movements on the Company’s derivatives, equity securities and investments accounted for under the fair value option method. Net realized gains for the 2024 second quarter also included a benefit on the sale of a subsidiary.
On a pre-tax basis, net foreign exchange gains for the 2024 second quarter were $1 million, compared to net foreign exchange losses of $5 million for the 2023 second quarter. For both periods, such amounts were primarily unrealized and resulted from the effects of revaluing the Company’s net insurance liabilities required to be settled in foreign currencies at each balance sheet date. Changes in the value of available-for-sale investments held in foreign currencies due to foreign currency rate movements are reflected as a direct increase or decrease to shareholders’ equity and are not included in the consolidated statements of income.
The Company’s effective tax rate on income before income taxes (based on the Company’s estimated annual effective tax rate) was 7.1% for the 2024 second quarter, compared to 9.2% for the 2023 second quarter. The Company’s effective tax rate on pre-tax operating income available to Arch common shareholders was 9.5% for the 2024 second quarter, compared to 8.0% for the 2023 second quarter. The effective tax rate may fluctuate from period to period based upon the relative mix of income or loss reported by jurisdiction, the level of catastrophic loss activity incurred, and the varying tax rates in each jurisdiction.
Income from operating affiliates for the 2024 second quarter was $45 million, or $0.12 per share, compared to $22 million, or $0.06 per share, for the 2023 second quarter, and primarily reflects amounts related to the Company’s investment in Somers Group Holdings Ltd. and Coface SA.

Comments on Non-GAAP Financial Measures
Throughout this release, the Company presents its operations in the way it believes will be the most meaningful and useful to investors, analysts, rating agencies and others who use the Company’s financial information in evaluating the performance of the Company and that investors and such other persons benefit from having a consistent basis for comparison between quarters and for comparison with other companies within the industry. These measures may not, however, be comparable to similarly titled measures used by companies outside of the insurance industry. Investors are cautioned not to place undue reliance on these non-GAAP financial measures in assessing the Company’s overall financial performance.
This presentation includes the use of “after-tax operating income or loss available to Arch common shareholders,” which is defined as net income available to Arch common shareholders, excluding net realized gains or losses (which includes realized and unrealized changes in the fair value of equity securities and assets accounted for using the fair value option, realized and unrealized gains and losses on derivative instruments, changes in the allowance for credit losses on financial assets and gains and losses realized from the acquisition or disposition of subsidiaries), equity in net income or loss of investment funds accounted for using the equity method, net foreign exchange gains or losses, transaction costs and other, net of income taxes and the use of annualized operating return on average common equity. The presentation of after-tax operating income available to Arch common shareholders and annualized operating return on average common equity are non-GAAP financial measures as defined in Regulation G. The reconciliation of such measures to net income available to Arch common shareholders and annualized net income return on average common equity (the most directly comparable GAAP financial measures) in accordance with Regulation G is included on page 2 of this release.
The Company believes that net realized gains or losses, equity in net income or loss of investment funds accounted for using the equity method, net foreign exchange gains or losses and transaction costs and other, in any particular period are not indicative of the performance of, or trends in, the Company’s business performance. Although net realized gains or losses, equity in net income or loss of investment funds accounted for using the equity method and net foreign exchange gains or losses are an integral part of the Company’s operations, the decision to realize these items are independent of the insurance underwriting process and result, in large part, from general economic and financial market conditions. Furthermore, certain users of the Company’s financial information believe that, for many companies, the timing of the realization of investment gains or losses is largely opportunistic. In addition, changes in the allowance for credit losses and net impairment losses recognized in earnings on the Company’s investments represent other-than-temporary declines in expected recovery values on securities without actual realization.
The use of the equity method on certain of the Company’s investments in certain funds that invest in fixed maturity securities is driven by the ownership structure of such funds (either limited partnerships or limited liability companies). In applying the equity method, these investments are initially recorded at cost and are subsequently adjusted based on the Company’s proportionate share of the net income or loss of the funds (which include changes in the fair value of the underlying securities in the funds). This method of accounting is different from the way the Company accounts for its other fixed maturity securities and the timing of the recognition of equity in net income or loss of investment funds accounted for using the equity method may differ from gains or losses in the future upon sale or maturity of such investments.
Transaction costs and other include advisory, financing, legal, severance, incentive compensation and other costs related to acquisitions. The Company believes that transaction costs and other, due to their non-recurring nature, are not indicative of the performance of, or trends in, the Company’s business performance.
7


In the 2023 fourth quarter, the Company established a net deferred tax benefit of $1.18 billion consistent with the transition provisions specified in the Bermuda Corporate Income Tax Act of 2023. Due to the non-recurring nature of this one-time item, the Company believes that excluding this item from after-tax operating income or loss available to common shareholders provides the user with a better evaluation of the Company’s ongoing business performance.
The Company believes that showing net income available to Arch common shareholders exclusive of the items referred to above reflects the underlying fundamentals of the Company’s business since the Company evaluates the performance of and manages its business to produce an underwriting profit. In addition to presenting net income available to Arch common shareholders, the Company believes that this presentation enables investors and other users of the Company’s financial information to analyze the Company’s performance in a manner similar to how the Company’s management analyzes performance. The Company also believes that this measure follows industry practice and, therefore, allows the users of the Company’s financial information to compare the Company’s performance with its industry peer group. The Company believes that the equity analysts and certain rating agencies that follow the Company and the insurance industry as a whole generally exclude these items from their analyses for the same reasons.
The Company’s segment information includes the presentation of consolidated underwriting income or loss and a subtotal of underwriting income or loss. Such measures represent the pre-tax profitability of its underwriting operations and include net premiums earned plus other underwriting income, less losses and loss adjustment expenses, acquisition expenses and other operating expenses. Other operating expenses include those operating expenses that are incremental and/or directly attributable to the Company’s individual underwriting operations. Underwriting income or loss does not include certain income and expense items which are included in corporate. While these measures are presented in the Segment Information footnote to the Company’s Consolidated Financial Statements, they are considered non-GAAP financial measures when presented elsewhere on a consolidated basis. The reconciliations of underwriting income or loss to income before income taxes (the most directly comparable GAAP financial measure) on a consolidated basis, in accordance with Regulation G, is shown on the following pages.
Management measures segment performance for its three underwriting segments based on underwriting income or loss. The Company does not manage its assets by underwriting segment and, accordingly, investment income, income from operating affiliates and other items are not allocated to each underwriting segment.
In addition, the Company’s segment information includes the use of a combined ratio excluding catastrophic activity and prior year development, for the insurance and reinsurance segments, and a combined ratio excluding prior year development, for the mortgage segment. These ratios are non-GAAP financial measures as defined in Regulation G. The reconciliation of such measures to the combined ratio (the most directly comparable GAAP financial measure) in accordance with Regulation G are shown on the individual segment pages. The Company’s management utilizes the adjusted combined ratios excluding current accident year catastrophic events and favorable or adverse development in prior year loss reserves in its analysis of the underwriting performance of each of its underwriting segments.
Total return on investments includes investment income, equity in net income or loss of investment funds accounted for using the equity method, net realized gains and losses (excluding changes in the allowance for credit losses on non-investment related financial assets) and the change in unrealized gains and losses generated by Arch’s investment portfolio. Total return is calculated on a pre-tax basis and before investment expenses and reflects the effect of financial market conditions along with foreign currency fluctuations. Management uses total return on investments as a key measure of the return generated to Arch common shareholders, and compares the return generated by the Company’s investment portfolio against benchmark returns during the periods presented.

All statements other than statements of historical fact included in or incorporated by reference in this release are forward-looking statements. Forward-looking statements, for purposes of the PSLRA or otherwise, can generally be identified by the use of forward-looking terminology such as “may,” “will,” “expect,” “intend,” “estimate,” “anticipate,” “believe” or “continue” and similar statements of a future or forward-looking nature or their negative or variations or similar terminology.
Forward-looking statements involve the Company’s current assessment of risks and uncertainties. Actual events and results may differ materially from those expressed or implied in these statements. Important factors that could cause actual events or results to differ materially from those indicated in such statements are discussed below and elsewhere in this release and in the Company’s periodic reports filed with the Securities and Exchange Commission (the “SEC”), and include:

•greater than expected loss ratios on business written by the Company and adverse development on claim and/or claim expense liabilities related to business written by its insurance and reinsurance subsidiaries;
•the adequacy of the Company’s loss reserves;
•severity and/or frequency of losses;
•greater frequency or severity of unpredictable natural and man-made catastrophic events;
•claims resulting from natural or man-made catastrophic events or severe economic events in the Company’s insurance, reinsurance and mortgage businesses could cause large losses and substantial volatility in the Company’s results of operations;
•the effect of climate change on the Company’s business;
•the effect of contagious diseases (including COVID-19) on the Company’s business;

•changes in accounting principles or policies or in the Company’s application of such accounting principles or policies;
•changes in the political environment of certain countries in which the Company operates, underwrites business or invests;

Arch Capital Group Ltd. and Subsidiaries
Segment Information — Overview

The Company’s Insurance, Reinsurance and Mortgage segments each have managers who are responsible for the overall profitability of their respective segments and who are directly accountable to the Company’s chief operating decision makers, the Chief Executive Officer, the Chief Financial Officer and Treasurer and the President and Chief Underwriting Officer. The chief operating decision makers do not assess performance, measure return on equity or make resource allocation decisions on a line of business basis. Management measures segment performance for its three underwriting segments based on underwriting income or loss. The Company does not manage its assets by underwriting segment and, accordingly, investment income is not allocated to each underwriting segment.
The Company determined its reportable operating segments using the management approach described in accounting guidance regarding disclosures about segments of an enterprise and related information. The accounting policies of the segments are the same as those used for the preparation of the Company’s consolidated financial statements. Intersegment business is allocated to the segment accountable for the underwriting results.
Insurance Segment
The insurance segment consists of the Company’s insurance underwriting units which offer specialty product lines on a worldwide basis. Product lines include:
•    Construction and national accounts: primary and excess casualty coverages for middle market and large construction accounts, a comprehensive range of products for middle market accounts in specialty industries and casualty solutions for large national accounts, including loss sensitive primary insurance programs (large deductible, self-insured retention and retrospectively rated programs).
•    Excess and surplus casualty: primary and excess casualty insurance coverages written on a non-admitted basis.
•    Professional lines: directors’ and officers’ liability, errors and omissions liability, employment practices liability, fiduciary liability, crime, professional indemnity and other financial related coverages for corporate, private equity, venture capital, real estate investment trust, limited partnership, financial institution and not-for-profit clients of all sizes, cyber insurance, and medical professional and general liability insurance coverages for the healthcare industry. The business is predominately written on a claims-made basis.
•    Programs: primarily targeting program managers with unique expertise and niche products offering some combination of general liability, commercial automobile, property, inland marine, umbrella and workers’ compensation.
•    Property, energy, marine and aviation: primary and excess general property insurance coverages, including catastrophe-exposed property coverage, for commercial clients. Coverages for marine include hull, cargo, war, specie and liability. Aviation, standalone terrorism and political risks are also offered. Coverage may be provided for operational and construction risk.
•    Travel, accident and health: specialty travel and accident and related insurance products for individual, group travelers, travel agents and suppliers, as well as accident and health, which provides accident, disability and medical plan insurance coverages for employer groups, medical plan members, students and other participant groups.
•Warranty and lenders solutions: collateral protection, debt cancellation and service contract reimbursement products to banks, credit unions, automotive dealerships and original equipment manufacturers and other specialty programs that pertain to automotive lending and leasing.
•    Other: includes alternative market risks (including captive insurance programs), excess workers’ compensation and employer’s liability insurance coverages for qualified self-insured groups, associations and trusts, and contract, commercial and transactional surety coverages.

Reinsurance Segment
The reinsurance segment consists of the Company’s reinsurance underwriting units which offer specialty product lines on a worldwide basis. Reinsurance agreements are typically offered on a proportional and/or excess of loss basis and provide coverage to ceding company clients for specific underlying written policies. Product lines include:
•Casualty: provides coverage on third party liability exposures including, among others, executive assurance, professional liability, excess and umbrella liability, excess motor and healthcare business, and workers’ compensation. Business is assumed primarily on a treaty basis, with some facultative coverages also offered.
•Marine and aviation: provides coverage for energy, hull, cargo, specie, liability and transit, and aviation business, including airline and general aviation risks. Business written may also include space business, which includes coverages for satellite assembly, launch and operation for commercial space programs.
•Other specialty: provides coverage for proportional motor reinsurance, whole account multi-line treaties, cyber, trade credit and surety, accident and health, workers’ compensation catastrophe, agriculture and political risk, among others.
•Property catastrophe: provides protection for most types of catastrophic losses, including hurricane, earthquake, flood, tornado, hail and fire, and for other perils on a case-by-case basis. Excess of loss coverages are triggered when aggregate losses and loss adjustment expense from a single occurrence of a covered peril exceed the retention specified in the contract.
•Property excluding property catastrophe: provides coverage for personal lines and/or commercial property exposures and principally covers buildings, structures, equipment and contents. The primary perils in this business include fire, explosion, collapse, riot, vandalism, wind, tornado, flood and earthquake. Business is assumed on either a treaty or facultative basis.
•Other: primarily includes life reinsurance business.
Mortgage Segment
The mortgage segment includes the Company’s underwriting units which offer mortgage insurance and reinsurance products on a worldwide basis. Underwriting units include:
•U.S. primary mortgage insurance: offers private mortgage insurance through Arch Mortgage Insurance Company and United Guaranty Residential Insurance Company (combined “Arch MI U.S.”), both approved eligible mortgage insurers by Fannie Mae and Freddie Mac. Arch MI U.S. also includes Arch Mortgage Guaranty Company, which is not a government sponsored enterprise (“GSE”) approved entity.
•U.S. credit risk transfer (“CRT”) and other: underwrites CRT transactions, which are predominantly with GSEs, and other U.S. reinsurance transactions.
•International mortgage insurance/reinsurance: underwrites mortgage insurance and reinsurance outside of the U.S.
The Company’s results also include net investment income, net realized gains or losses (which includes realized and unrealized changes in the fair value of equity securities and assets accounted for using the fair value option, realized and unrealized gains and losses on derivative instruments, changes in the allowance for credit losses on financial assets and gains and losses realized from acquisition or disposition of subsidiaries), equity in net income or loss of investment funds accounted for using the equity method, other income (loss), corporate expenses, transaction costs and other, amortization of intangible assets, interest expense, net foreign exchange gains or losses, income taxes items (which for the 2023 fourth quarter reflects the establishment of a net deferred tax asset related to the enactment of Bermuda’s new corporate income tax), income or loss from operating affiliates and items related to the Company’s non cumulative preferred shares.

Comments on Non-GAAP Financial Measures
Throughout this financial supplement, the Company presents its operations in the way it believes will be the most meaningful and useful to investors, analysts, rating agencies and others who use the Company’s financial information in evaluating the performance of the Company. This presentation includes the use of after-tax operating income available to Arch common shareholders, which is defined as net income available to Arch common shareholders, excluding net realized gains or losses (which includes realized and unrealized changes in the fair value of equity securities and assets accounted for using the fair value option, realized and unrealized gains and losses on derivative instruments, changes in the allowance for credit losses on financial assets and gains and losses realized from the acquisition or disposition of subsidiaries), equity in net income or loss of investment funds accounted for using the equity method, net foreign exchange gains or losses, transaction costs and other, net of income taxes and the use of annualized operating return on average common equity. The presentation of after-tax operating income available to Arch common shareholders and annualized operating return on average common equity are non-GAAP financial measures as defined in Regulation G. The reconciliation of such measures to net income available to Arch common shareholders and annualized net income return on average common equity (the most directly comparable GAAP financial measures) in accordance with Regulation G is included on the following page.
The Company believes that net realized gains or losses, equity in net income or loss of investment funds accounted for using the equity method, net foreign exchange gains or losses and transaction costs and other, in any particular period are not indicative of the performance of, or trends in, the Company’s business. Although net realized gains or losses, equity in net income or loss of investment funds accounted for using the equity method and net foreign exchange gains or losses are an integral part of the Company’s operations, the decision to realize these items are independent of the insurance underwriting process and result, in large part, from general economic and financial market conditions. Furthermore, certain users of the Company’s financial information believe that, for many companies, the timing of the realization of investment gains or losses is largely opportunistic. In addition, changes in the allowance for credit losses and net impairment losses recognized in earnings on the Company’s investments represent other-than-temporary declines in expected recovery values on securities without actual realization.
The use of the equity method on certain of the Company’s investments in certain funds that invest in fixed maturity securities is driven by the ownership structure of such funds (either limited partnerships or limited liability companies). In applying the equity method, these investments are initially recorded at cost and are subsequently adjusted based on the Company’s proportionate share of the net income or loss of the funds (which include changes in the fair value of the underlying securities in the funds). This method of accounting is different from the way the Company accounts for its other fixed maturity securities and the timing of the recognition of equity in net income or loss of investment funds accounted for using the equity method may differ from gains or losses in the future upon sale or maturity of such investments.
Transaction costs and other include advisory, financing, legal, severance, incentive compensation and other transaction costs related to acquisitions. The Company believes that transaction costs and other, due to their non-recurring nature, are not indicative of the performance of, or trends in, the Company’s business performance.
In the 2023 fourth quarter, the Company established a net deferred tax benefit of $1.18 billion consistent with the transition provisions specified in the Bermuda Corporate Income Tax Act of 2023. Due to the non-recurring nature of this one-time item, the Company believes that excluding this item from after-tax operating income or loss available to common shareholders provides the user with a better evaluation of the Company’s ongoing business performance.
The Company believes that showing net income available to Arch common shareholders exclusive of the items referred to above reflects the underlying fundamentals of the Company’s business since the Company evaluates the performance of and manages its business to produce an underwriting profit. In addition to presenting net income available to Arch common shareholders, the Company believes that this presentation enables investors and other users of the Company’s financial information to analyze the Company’s performance in a manner similar to how the Company’s management analyzes performance. The Company also believes that this measure follows industry practice and, therefore, allows the users of the Company’s financial information to compare the Company’s performance with its industry peer group. The Company believes that the equity analysts and certain rating agencies that follow the Company and the insurance industry as a whole generally exclude these items from their analyses for the same reasons.
The Company’s segment information includes the presentation of consolidated underwriting income or loss and a subtotal of underwriting income or loss. Such measures represent the pre-tax profitability of the Company’s underwriting operations and include net premiums earned plus other underwriting income, less losses and loss adjustment expenses, acquisition expenses and other operating expenses. Other operating expenses include those operating expenses that are incremental and/or directly attributable to the Company’s individual underwriting operations. Underwriting income or loss does not include certain income and expense items which are included in corporate. While these measures are presented in the Segment Information footnote to the Company’s Consolidated Financial Statements, they are considered non-GAAP financial measures when presented elsewhere on a consolidated basis. The reconciliations of underwriting income or loss to income before income taxes (the most directly comparable GAAP financial measure) on a consolidated basis, in accordance with Regulation G, is shown on pages 9 to 12.
In addition, the Company’s segment information includes the use of a combined ratio excluding catastrophic activity and prior year development, for the insurance and reinsurance segments, and a combined ratio excluding prior year development, for the mortgage segment. These ratios are non-GAAP financial measures as defined in Regulation G. The reconciliation of such measures to the combined ratio (the most directly comparable GAAP financial measure) in accordance with Regulation G are shown on the individual segment pages. The Company’s management utilizes the adjusted combined ratios excluding current accident year catastrophic events and favorable or adverse development in prior year loss reserves in its analysis of the underwriting performance of each of its underwriting segments.
Total return on investments includes investment income, equity in net income or loss of investment funds accounted for using the equity method, net realized gains and losses (excluding changes in the allowance for credit losses on non-investment related financial assets) and the change in unrealized gains and losses generated by the Company’s investment portfolio. Total return is calculated on a pre-tax basis and before investment expenses, and reflects the effect of financial market conditions along with foreign currency fluctuations. Management uses total return on investments as a key measure of the return generated to Arch common shareholders, and compares the return generated by the Company’s investment portfolio against benchmark returns during the periods presented.
