ARCH CAPITAL GROUP LTD. REPORTS 2025 FIRST QUARTER RESULTS

PEMBROKE, BERMUDA--(BUSINESS WIRE)--Arch Capital Group Ltd. (NASDAQ: ACGL; “Arch,” “our” or “the Company”) announces its 2025 first quarter results. The results included:
•Net income available to Arch common shareholders of $564 million, or $1.48 per share, representing an 11.1% annualized net income return on average common equity, compared to net income available to Arch common shareholders of $1.1 billion, or $2.92 per share, for the 2024 first quarter.
•After-tax operating income available to Arch common shareholders(1) of $587 million, or $1.54 per share, representing an 11.5% annualized operating return on average common equity(1), compared to $933 million, or $2.45 per share, for the 2024 first quarter.
•Pre-tax current accident year catastrophic losses for the Company’s insurance and reinsurance segments, net of reinsurance and reinstatement premiums, of $547 million, primarily related to the California wildfires.
•Favorable development in prior year loss reserves, net of related adjustments, of $167 million.
•Combined ratio excluding catastrophic activity and prior year development(1) of 81.0%, compared to 80.8% for the 2024 first quarter.
•Share repurchases of approximately $196 million.
•Book value per common share of $55.15 at March 31, 2025, a 3.8% increase from December 31, 2024.
Nicolas Papadopoulo, Arch CEO, commented, “We delivered solid results this quarter despite the losses arising from the California wildfires, resulting in an annualized operating return on equity of 11.5%. Although the market has generally become more competitive, we remain optimistic about our prospects to deliver long-term shareholder value. For a company with a strong underwriting culture like Arch, this is a market where we can stand out.”

Segment Information
The following section provides analysis on the Company’s 2025 first quarter performance by reportable segments. For additional details regarding the Company’s reportable segments, please refer to the Company’s Financial Supplement dated March 31, 2025. 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 March 31,
(U.S. Dollars in millions) 2025 2024 % Change
Gross premiums written $ 2,645  $ 2,126  24.4

Underwriting income $ (2) $ 86  (102.3)
Underwriting Ratios % Point Change
Loss ratio 66.0  % 58.9  % 7.1 
Underwriting expense ratio 34.1  % 35.2  % (1.1)
Combined ratio 100.1  % 94.1  % 6.0 
Catastrophic activity and prior year development:
Current accident year catastrophic events, net of reinsurance and reinstatement premiums 9.5  % 1.9  % 7.6 
Net (favorable) adverse development in prior year loss reserves, net of related adjustments (0.5) % (0.5) % — 
Combined ratio excluding catastrophic activity and prior year development 91.1  % 92.7  % (1.6)

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 2025 first quarter results include a full quarter of activity related to the acquired business.
Gross premiums written by the insurance segment in the 2025 first quarter were 24.4% higher than in the 2024 first quarter (4.8% excluding the MCE Acquisition), while net premiums written were 25.4% higher than in the 2024 first quarter (1.2% excluding the MCE Acquisition). Growth in net premiums written excluding the impact of the MCE Acquisition reflected an increase in commercial automobile and other liability–occurrence due, in part, to new business opportunities and rate changes. These increases were mostly offset by reductions in other liability–claims made where markets remained competitive. Net premiums earned in the 2025 first quarter were 28.2% higher than in the 2024 first quarter (1.7% excluding the MCE Acquisition), and reflect changes in net premiums written over the previous five quarters.
The 2025 first quarter loss ratio reflected 9.5 points of current year catastrophic activity, primarily related to the California wildfires, compared to 2.1 points of activity related to the Baltimore bridge collapse along with 1.9 points of current year catastrophic activity in the 2024 first quarter. Estimated net favorable development of prior year loss reserves, before related adjustments, reduced the loss ratio by 0.9 points in the 2025 first quarter, compared to 0.7 points in the 2024 first quarter. The balance of the change in the loss ratio resulted, in part, from the impact of the MCE Acquisition business and changes in the mix of business.
The underwriting expense ratio was 34.1% in the 2025 first quarter, compared to 35.2% in the 2024 first quarter. The impact of the MCE Acquisition lowered the underwriting expense ratio by approximately 1.9 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 is considered within the value of business acquired, which is amortized through amortization of intangibles.

Reinsurance Segment
Three Months Ended March 31,
(U.S. Dollars in millions) 2025 2024 % Change
Gross premiums written $ 3,494  $ 3,467  0.8 
Net premiums written 2,316  2,266  2.2 
Net premiums earned 2,028  1,666  21.7 
Other underwriting income 39  1,850.0 
Underwriting income $ 167  $ 379  (55.9)
Underwriting Ratios % Point Change
Loss ratio 66.9  % 53.0  % 13.9 
Underwriting expense ratio 24.9  % 24.4  % 0.5 
Combined ratio 91.8  % 77.4  % 14.4 
Catastrophic activity and prior year development:
Current accident year catastrophic events, net of reinsurance and reinstatement premiums 18.3  % 1.8  % 16.5 
Net (favorable) adverse development in prior year loss reserves, net of related adjustments (4.5) % (2.5) % (2.0)
Combined ratio excluding catastrophic activity and prior year development 78.0  % 78.1  % (0.1)
Gross premiums written by the reinsurance segment in the 2025 first quarter were 0.8% higher than in the 2024 first quarter, while net premiums written were 2.2% higher than in the 2024 first quarter. The growth in net premiums written primarily reflected increases in casualty, property catastrophe and property excluding property catastrophe lines, due in part to rate increases, new business opportunities and growth in existing accounts. These increases were mostly offset by reductions in specialty lines due to non-renewals of structured deals and share reductions. Net premiums earned in the 2025 first quarter were 21.7% higher than in the 2024 first quarter, and reflect changes in net premiums written over the previous five quarters.
The 2025 first quarter loss ratio reflected 21.7 points of current year catastrophic activity, primarily related to the California wildfires, compared to 3.0 points related to the Baltimore bridge collapse along with 1.9 points of current year catastrophic activity in the 2024 first quarter. Estimated net favorable development of prior year loss reserves, before related adjustments, reduced the loss ratio by 5.9 points in the 2025 first quarter, compared to 2.4 points in the 2024 first 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 24.9% in the 2025 first quarter, compared to 24.4% in the 2024 first quarter, with the increase reflecting lower contingent commissions on ceded business in the 2025 first quarter due to higher loss activity.

Mortgage Segment
Three Months Ended March 31,
(U.S. Dollars in millions) 2025 2024 % Change
Gross premiums written $ 326  $ 341  (4.4)
Net premiums written 266  277  (4.0)
Net premiums earned 300  305  (1.6)
Other underwriting income 11  10  10.0 
Underwriting income $ 252  $ 271  (7.0)
Underwriting Ratios % Point Change
Loss ratio 1.1  % (3.0) % 4.1 
Underwriting expense ratio 15.0  % 17.5  % (2.5)
Combined ratio 16.1  % 14.5  % 1.6 
Prior year development:
Net (favorable) adverse development in prior year loss reserves, net of related adjustments (21.8) % (25.7) % 3.9 
Combined ratio excluding prior year development 37.9  % 40.2  % (2.3)
Gross premiums written by the mortgage segment in the 2025 first quarter were 4.4% lower than in the 2024 first quarter, while net premiums written were 4.0% lower. The decrease in net premiums written in the 2025 first quarter primarily reflected a lower level of mortgage originations, mostly in our international businesses.
Estimated net favorable development of prior year loss reserves, before related adjustments, decreased the loss ratio by 20.4 points, compared to 24.4 points in the 2024 first quarter. Such amounts were primarily related to better than expected cure rates. The 2025 first quarter loss ratio, excluding net favorable development, was consistent with the 2024 first quarter.
The underwriting expense ratio was 15.0% in the 2025 first quarter, compared to 17.5% in the 2024 first quarter.

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
March 31, December 31, March 31,
2025 2024 2024
Pre-tax net investment income $ 378  $ 405  $ 327 
Per share $ 0.99  $ 1.06  $ 0.86 
Equity in net income (loss) of investment funds accounted for using the equity method $ 53  $ 143  $ 99 
Per share $ 0.14  $ 0.37  $ 0.26 
Pre-tax investment income yield, at amortized cost (1) 4.16  % 4.32  % 4.14  %
Total return on investments (2) 2.02  % (1.05) % 0.80  %
(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.
Net investment income for the 2025 first quarter reflected the impact of a reduction of investable assets related to the special cash dividend to common shareholders of $1.9 billion paid in December 2024, along with higher investment expenses primarily related to incentive compensation in the period. Net realized gains were $3 million for the 2025 first quarter, compared to net realized gains of $67 million in the 2024 first 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.
Amortization of intangible assets was $49 million for the 2025 first quarter, compared to $21 million for the 2024 first quarter. The higher level of expense for the 2025 first 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 $10 million for the 2025 first quarter, compared to $7 million for the 2024 first quarter. The 2025 first quarter primarily includes direct costs related to the MCE Acquisition and ongoing integration efforts.
On a pre-tax basis, net foreign exchange losses were $27 million for the 2025 first quarter, compared to net foreign exchange gains of $31 million for the 2024 first 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 annual effective tax rate) was an expense of 17.4% for the 2025 first quarter, compared to 8.3% for the 2024 first quarter. The Company’s effective tax rate on pre-tax operating income available to Arch common shareholders was 11.7% for the 2025 first quarter, compared to 8.5% for the 2024 first 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 2025 first quarter was $17 million, or $0.04 per share, compared to $55 million, or $0.14 per share, for the 2024 first quarter, and primarily reflects amounts related to the Company’s investment in Somers Group Holdings Ltd. and Coface SA.

The Financial Supplement provides additional detail regarding the financial performance of the Company.

Arch Capital Group Ltd., is a publicly listed Bermuda exempted company with approximately $24.3 billion in capital at March 31, 2025. 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.
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.

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. Effective in the 2025 first quarter, the ‘Other operating expense ratio’ includes ‘Other underwriting income (loss).’
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.

•severity and/or frequency of losses;

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; 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, income or loss from operating affiliates and items related to the Company’s non cumulative preferred shares.

(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 became effective on 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 March 31, 2025, the changes would have reduced available assets by 17% and resulted in a pro-forma PMIERs Sufficiency Ratio of 163% 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.

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 10.
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. Effective in the 2025 first quarter, the ‘Other operating expense ratio’ includes ‘Other underwriting income (loss).’
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.
