ARCH CAPITAL GROUP LTD. REPORTS 2024 FOURTH QUARTER RESULTS

PEMBROKE, BERMUDA--(BUSINESS WIRE)--Arch Capital Group Ltd. (NASDAQ: ACGL; “Arch,” “our” or “the Company”) announces its 2024 fourth quarter results. The results included:
•Net income available to Arch common shareholders of $925 million, or $2.42 per share, representing a 17.9% annualized net income return on average common equity, compared to net income available to Arch common shareholders of $2.3 billion, or $6.12 per share, for the 2023 fourth quarter.
•After-tax operating income available to Arch common shareholders(1) of $866 million, or $2.26 per share, representing a 16.7% annualized operating return on average common equity(1), compared to $945 million, or $2.49 per share, for the 2023 fourth quarter.
•Pre-tax current accident year catastrophic losses for the Company’s insurance and reinsurance segments, net of reinsurance and reinstatement premiums, of $393 million, due in part to Hurricanes Milton and Helene.
•Favorable development in prior year loss reserves, net of related adjustments, of $146 million.
•Combined ratio excluding catastrophic activity and prior year development(1) of 79.0%, compared to 78.9% for the 2023 fourth quarter.
•Share repurchases of approximately $24 million, in addition to the already communicated special cash dividend to common shareholders of $1.9 billion, or $5.00 per share, paid on December 4, 2024.
•Book value per common share of $53.11 at December 31, 2024, a 6.8% decrease from September 30, 2024 (or a 1.9% increase excluding the impact of the special cash dividend noted above).
Nicolas Papadopoulo, Arch CEO, commented “We closed the year with a very strong fourth quarter including contributions from all our earnings sources. These are excellent results when you consider the elevated catastrophe environment and the increased risk levels across many lines of business.” Papadopoulo added, “Additionally, on behalf of everyone at Arch, I would like to offer our thoughts and sympathies to everyone affected by the California wildfires. This devastating event will require the coordinated efforts of many, particularly the insurance industry, to help rebuild. While still too early to fully assess the magnitude of this disaster, our current view of the insured market loss will be between $35 billion and $45 billion, making Arch's expected share of the event somewhere between $450 million and $550 million.”

Segment Information
The following section provides analysis on the Company’s 2024 fourth quarter performance by reportable segments. For additional details regarding the Company’s reportable segments, please refer to the Company’s Financial Supplement dated December 31, 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).
Insurance Segment
Three Months Ended December 31,
(U.S. Dollars in millions) 2024 2023 % Change
Gross premiums written $ 2,484  $ 1,934  28.4 
Net premiums written 1,954  1,449  34.9 
Net premiums earned 1,933  1,449  33.4 
Underwriting income $ 30  $ 99  (69.7)
Underwriting Ratios % Point Change
Loss ratio 66.3  % 58.4  % 7.9 
Underwriting expense ratio 32.2  % 34.7  % (2.5)
Combined ratio 98.5  % 93.1  % 5.4 
Catastrophic activity and prior year development:
Current accident year catastrophic events, net of reinsurance and reinstatement premiums 8.3  % 3.8  % 4.5 
Net (favorable) adverse development in prior year loss reserves, net of related adjustments (0.1) % (0.5) % 0.4 
Combined ratio excluding catastrophic activity and prior year development 90.3  % 89.8  % 0.5 
On August 1, 2024, the insurance segment completed the acquisition of the U.S. MidCorp and Entertainment insurance businesses from Allianz (“MCE Acquisition”). As such, the insurance segment’s 2024 fourth quarter results include a full quarter of activity related to the acquired business.
Gross premiums written by the insurance segment in the 2024 fourth quarter were 28.4% higher than in the 2023 fourth quarter (8.1% excluding the MCE Acquisition), while net premiums written were 34.9% higher than in the 2023 fourth quarter (7.7% excluding the MCE Acquisition). Growth in net premiums written included the impact of the MCE Acquisition and also reflected an increase in property and short-tail specialty and other liability—occurrence due, in part, to new business opportunities and rate changes. Net premiums earned in the 2024 fourth quarter were 33.4% higher than in the 2023 fourth quarter (7.1% excluding the MCE Acquisition), and reflect changes in net premiums written over the previous five quarters.
The 2024 fourth quarter loss ratio reflected 8.3 points of current year catastrophic activity, primarily related to Hurricanes Helene and Milton, compared to 3.8 points of catastrophic activity in the 2023 fourth quarter. Estimated net favorable development of prior year loss reserves, before related adjustments, reduced the loss ratio by 0.3 points in the 2024 fourth quarter, compared to 0.6 points in the 2023 fourth quarter. The balance of the change in the loss ratio resulted, in part, from the impact of the MCE Acquisition business, certain adjustments to current accident year loss picks for select lines of business and changes in the mix of business.
The underwriting expense ratio was 32.2% in the 2024 fourth quarter, compared to 34.7% in the 2023 fourth quarter. The impact of the MCE Acquisition lowered the underwriting expense ratio by approximately 2.9 points, primarily due to the effects of the fair value estimation of the assets acquired at closing, including the non-recognition of deferred acquisition costs. The value of policies in force at closing are considered within the value of business acquired which is amortized through amortization of intangibles. The underwriting expense ratio also benefited from an initial lower level of operating expenses in the acquired business.

Reinsurance Segment
Three Months Ended December 31,
(U.S. Dollars in millions) 2024 2023 % Change
Gross premiums written $ 1,941  $ 1,971  (1.5)
Net premiums written 1,588  1,557  2.0 
Net premiums earned 1,904  1,620  17.5 
Other underwriting income (50.0)
Underwriting income $ 328  $ 330  (0.6)
Underwriting Ratios % Point Change
Loss ratio 58.9  % 52.3  % 6.6 
Underwriting expense ratio 24.1  % 27.7  % (3.6)
Combined ratio 83.0  % 80.0  % 3.0 
Catastrophic activity and prior year development:
Current accident year catastrophic events, net of reinsurance and reinstatement premiums 12.2  % 5.1  % 7.1 
Net (favorable) adverse development in prior year loss reserves, net of related adjustments (4.0) % (1.3) % (2.7)
Combined ratio excluding catastrophic activity and prior year development 74.8  % 76.2  % (1.4)
Gross premiums written by the reinsurance segment in the 2024 fourth quarter were 1.5% lower than in the 2023 fourth quarter, while net premiums written were 2.0% higher than in the 2023 fourth quarter. The growth in net premiums written primarily reflected increases in casualty, property excluding property catastrophe and property catastrophe lines, due in part to rate increases, new business opportunities and growth in existing accounts. Net premiums earned in the 2024 fourth quarter were 17.5% higher than in the 2023 fourth quarter, and reflect changes in net premiums written over the previous five quarters.
The 2024 fourth quarter loss ratio reflected 12.9 points of current year catastrophic activity, primarily related to Hurricane Milton, compared to 5.4 points of catastrophic activity in the 2023 fourth quarter. Estimated net favorable development of prior year loss reserves, before related adjustments, reduced the loss ratio by 3.8 points in the 2024 fourth quarter, compared to 1.6 points in the 2023 fourth quarter. The balance of the change in the loss ratio resulted, in part, from changes in the mix of business.
The underwriting expense ratio was 24.1% in the 2024 fourth quarter, compared to 27.7% in the 2023 fourth quarter, with the decrease reflecting lower contingent commissions in the 2024 fourth quarter, changes in mix of business and growth in net premiums earned.

Mortgage Segment
Three Months Ended December 31,
(U.S. Dollars in millions) 2024 2023 % Change
Gross premiums written $ 331  $ 350  (5.4)
Net premiums written 277  255  8.6 
Net premiums earned 306  275  11.3 
Other underwriting income — 
Underwriting income $ 267  $ 286  (6.6)
Underwriting Ratios % Point Change
Loss ratio (5.9) % (20.6) % 14.7 
Underwriting expense ratio 19.3  % 17.3  % 2.0 
Combined ratio 13.4  % (3.3) % 16.7 
Prior year development:
Net (favorable) adverse development in prior year loss reserves, net of related adjustments (22.3) % (39.0) % 16.7 
Combined ratio excluding prior year development 35.7  % 35.7  % — 
Gross premiums written by the mortgage segment in the 2024 fourth quarter were 5.4% lower than in the 2023 fourth quarter, while net premiums written were 8.6% higher. The increase in net premiums written and earned in the 2024 fourth 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 20.2 points, compared to 36.6 points in the 2023 fourth quarter. Such amounts were primarily related to better than expected cure rates. The 2024 fourth quarter loss ratio, excluding net favorable development, was slightly lower than in the 2023 fourth quarter.
The underwriting expense ratio was 19.3% in the 2024 fourth quarter, compared to 17.3% in the 2023 fourth quarter. The increase was primarily due to lower level of ceding and profit commissions on U.S. primary business, along with a higher level of operating expenses primarily related to one-time voluntary separation program costs.

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
December 31, September 30, December 31,
2024 2024 2023
Pre-tax net investment income $ 405  $ 399  $ 313 
Per share $ 1.06  $ 1.04  $ 0.82 
Equity in net income (loss) of investment funds accounted for using the equity method $ 143  $ 171  $ 102 
Per share $ 0.37  $ 0.45  $ 0.27 
Pre-tax investment income yield, at amortized cost (1) 4.32  % 4.40  % 4.11  %
Total return on investments (2) (1.05) % 3.97  % 4.76  %
(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 fourth quarter primarily reflected the effects of sustained higher interest rates available in the market. Net realized losses were $161 million for the 2024 fourth quarter, compared to net realized gains of $189 million in the 2023 fourth 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. Total return in the 2024 fourth quarter reflected unrealized losses on the Company’s fixed income securities, driven by higher interest rates.
Amortization of intangible assets was $99 million for the 2024 fourth quarter, compared to $24 million for the 2023 fourth quarter. The higher level of expense for the 2024 fourth quarter reflects the amortization of intangible assets related to the MCE Acquisition, including intangible assets attributed to value of business acquired and distribution relationships.
Transaction costs and other were $26 million for the 2024 fourth quarter, compared to $4 million for the 2023 fourth quarter. The 2024 fourth quarter primarily includes direct costs related to the MCE Acquisition and ongoing integration efforts.
On a pre-tax basis, net foreign exchange gains were $106 million for the 2024 fourth quarter, compared to net foreign exchange losses of $59 million for the 2023 fourth 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 was an expense of 6.6% for the 2024 fourth quarter, compared to a benefit of 85.6% for the 2023 fourth quarter. The income tax benefit in the 2023 fourth quarter was primarily driven by a $1.18 billion net deferred asset recorded in the 2023 fourth quarter. The Company’s effective tax rate on pre-tax operating income available to Arch common shareholders was 6.7% for the 2024 fourth quarter, compared to 7.3% for the 2023 fourth 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 fourth quarter was $64 million, or $0.17 per share, compared to $69 million, or $0.18 per share, for the 2023 fourth quarter, and primarily reflects amounts related to the Company’s investment in Somers Group Holdings Ltd. and Coface SA.

Arch Capital Group Ltd., is a publicly listed Bermuda exempted company with approximately $23.5 billion in capital at December 31, 2024. Arch, which is part of the S&P 500 index, provides insurance, reinsurance and mortgage insurance on a worldwide basis through its wholly owned subsidiaries.
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.
7


Transaction costs and other include integration, advisory, financing, legal, severance, incentive compensation and all other costs directly 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 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.

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 and the Chief Financial Officer and Treasurer. 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 Company’s insurance segment primarily consists of commercial insurance lines of business, with a focus on specialty insurance products. These products are mainly offered in North America, Bermuda, the United Kingdom, continental Europe and Australia. Products offered in North America include: commercial automobile; commercial multi‐peril; other liability—claims made, which includes financial and professional lines; other liability—occurrence, which includes admitted and excess and surplus casualty lines; property and short-tail specialty; workers compensation; and other. Products offered across the Company’s International units include: property and short-tail specialty; and casualty and other.
Reinsurance Segment
The Company’s reinsurance segment offers reinsurance products on a worldwide basis. Lines of business include: casualty; marine and aviation; other specialty; property catastrophe; property excluding property catastrophe; and other.
Mortgage Segment
The Company’s mortgage segment consists of U.S. primary mortgage insurance business written predominantly on loans sold to the Federal National Mortgage Association (“Fannie Mae”) and the Federal Home Loan Mortgage Corporation (“Freddie Mac”), each a government sponsored entity (“GSE”) and also through non GSE approved entities (combined “Arch MI U.S.”); reinsurance and underwriting services related to U.S. credit-risk transfer (“CRT”) business which are predominately with the GSEs and other U.S. mortgage reinsurance transactions; and international mortgage insurance and reinsurance business covering loans primarily in Australia and Europe.
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.

(3) Represents current (non-delinquent) RIF, net of reinsurance, divided by statutory capital (estimate for December 31, 2024).
(4) On August 21, 2024, Fannie Mae and Freddie Mac (collectively the GSEs) each updated their Private Mortgage Insurer Eligibility Requirements (PMIERs) to incorporate new deductions to available assets for investment risk. This update will become effective March 31, 2025; but the impact will be phased in through September 30, 2026. If the GSEs had fully implemented this update to PMIERs as of December 31, 2024, the changes would have reduced available assets by 17% and resulted in a pro-forma PMIERs Sufficiency Ratio of 154% compared with a reported PMIERs Sufficiency Ratio of 186%.

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.
