Form Type
10-Q

Rhea-AI Filing Summary

W. R. Berkley Corporation reported stronger profitability for the second quarter and first half of 2026. Net income to common stockholders was $452.3 million for the quarter and $967.5 million for the first six months, up from $401.3 million and $818.9 million a year earlier. Six‑month diluted EPS rose to $2.46 from $2.05. Net premiums earned grew to $3.19 billion in the quarter and $6.30 billion year‑to‑date, while net investment income increased to $418.7 million in Q2 and $823.0 million for the half. These gains were partly offset by net investment losses of $55.2 million in Q2 and $71.0 million year‑to‑date, compared with gains in 2025.

Total assets reached $45.68 billion at June 30, 2026, including $31.74 billion of investments and $2.61 billion of cash and cash equivalents. Reserves for losses and loss expenses rose to $23.18 billion, with modest adverse prior‑year development net of premium effects but some favorable property experience. Accumulated other comprehensive loss widened to $640.0 million, driven largely by unrealized losses on fixed‑maturity securities. Operating cash flow remained strong at $1.47 billion for the first half. Management highlights ongoing exposure to social inflation in auto‑related and liability lines and continued volatility from market‑sensitive investment strategies, including merger arbitrage and investment funds.

Positive

  • Six‑month 2026 net income to common stockholders increased to $967.5 million from $818.9 million, with diluted EPS rising to $2.46 from $2.05, supported by higher net premiums earned and higher net investment income.
  • Operating cash flow remained robust at $1.47 billion for the first half of 2026, while total assets grew to $45.68 billion and total stockholders’ equity edged up to $9.84 billion.

Negative

  • The company recorded $70.97 million of net investment losses in the first half of 2026 versus $47.33 million of gains a year earlier, and accumulated other comprehensive loss deepened to $640.0 million due mainly to declines in the fixed‑maturity portfolio.
  • Management reports adverse prior‑year development in umbrella, excess liability and auto‑related exposures, attributing higher large‑loss frequency and litigation costs in part to social inflation.

Filing Explained

First-half repurchases reduced outstanding common shares; MSI held 15.8% at June 30, while investment funds carried $241 million of unfunded commitments.

The company’s Form 10-Q is an unaudited interim report for the period ended June 30, 2026; it records 371,057,782 common shares outstanding net of treasury shares and common-treasury-share purchases in the first half.

This documents a completed reduction from 377,155,799 net shares at December 31, 2025, rather than a new issuance in the period.

The filing also states that Mitsui Sumitomo Insurance owned 15.8% of the company’s outstanding common stock at June 30, 2026; its board designee was elected at the 2026 annual meeting.

For investment funds, the company reports that it is not the primary beneficiary; its stated maximum exposure is the carrying amount plus unfunded commitments, which were $241 million at June 30, 2026.

A separate pending item is an appeal process involving reinsurers after an April 23, 2026 judgment; the final recoverable amount remains dependent on that process and additional costs.

merger arbitrage financial
"The primary focus of the trading account is <b>merger arbitrage</b>."
An investment strategy that tries to profit from the price difference between a company’s current stock and the price promised in a pending takeover or merger. Think of it like placing a bet that a planned sale will close: if the deal completes, the buyer’s promised price becomes real and the gap narrows, generating profit; if the deal fails, prices can move sharply the other way, so the approach matters because it offers targeted returns but carries event-driven risk.
variable interest entity financial
"The Company evaluates whether it is an investor in a <b>variable interest entity</b>."
A variable interest entity (VIE) is a company structure where one party controls another company’s operations and economic outcomes through contracts or special arrangements instead of owning a majority of its voting shares. For investors, VIEs matter because the controlling party’s financial results, debts and risks can appear in the controller’s reports even though ownership looks separate, so understanding VIEs helps assess true exposure, governance limits and transparency—like spotting a puppet controlled by strings rather than direct ownership.
incurred but not reported liabilities financial
"Reserves are also established on an aggregate basis to provide for <b>incurred but not reported liabilities</b>."
social inflation financial
"The Company believes that auto-related claims are being particularly impacted by <b>social inflation</b>."
A rise in insurance losses and legal payouts driven by changing social attitudes, more aggressive lawsuits, larger jury awards, and broader definitions of liability. It matters to investors because it can quietly increase an insurer’s claims costs and required reserves, reduce profits, and raise the risk of sudden losses—similar to a slowly rising tide that makes operating costs higher across the industry and can change how a company is valued.
Bornhuetter-Ferguson methods financial
"These methods include paid loss development, incurred loss development, paid and incurred <b>Bornhuetter-Ferguson methods</b>."
Level 3 securities financial
"For <b>Level 3 securities</b>, the Company generally uses a discounted cash flow model."

W. R. Berkley Corporation and Subsidiaries

NOTES TO INTERIM CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

(1) General
    The unaudited consolidated financial statements, which include the accounts of W. R. Berkley Corporation and its subsidiaries (the “Company”), have been prepared on the basis of U.S. generally accepted accounting principles (“GAAP”) for interim financial information. Accordingly, they do not include all the information and notes required by GAAP for annual financial statements. The unaudited consolidated financial statements reflect all adjustments, consisting only of normal recurring items, which are necessary to present fairly the Company’s financial position and results of operations on a basis consistent with the prior audited consolidated financial statements. Operating results for interim periods are not necessarily indicative of the results that may be expected for the year. All significant intercompany accounts and transactions have been eliminated.
The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the revenues and expenses reflected during the reporting period. For further information related to areas of judgment and estimates and other information necessary to understand the Company’s financial position and results of operations, refer to the audited consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025.
For interim periods, the income tax provision is based upon the Company’s estimated annual effective tax rate. This rate is generally greater than the federal income tax rate of 21%, primarily due to the geographical mix of earnings and amounts being subject to tax at a rate greater than the U.S. statutory rate and state taxes, which are partially offset by tax benefits related to tax-exempt investment income. Tax benefits related to equity-based compensation or other non-recurring items are discretely recorded in the period in which it occurs. During the six months ended June 30, 2026, the Company recognized a tax benefit relating to the repeal of undiscounted property-casualty loss deductions and special estimated payments formerly available under Internal Revenue Code Section 847, which was partially offset by deferred tax charges in the United Kingdom.


(2) Per Share Data
    The Company presents both basic and diluted net income per share (“EPS”) amounts. Basic EPS is calculated by dividing net income by the weighted average number of common shares outstanding during the period (including 17,378,810 and 17,659,297 common shares held in a grantor trust as of June 30, 2026 and 2025, respectively). The common shares held in the grantor trust are designated for delivery upon the settlement of restricted stock units ("RSUs") that are vested but mandatorily deferred. Accordingly, such shares deliverable under vested RSUs do not affect diluted shares outstanding since the shares are already included in basic shares outstanding (which includes the shares in the grantor trust referenced above). Diluted EPS is based upon the weighted average number of basic and common equivalent shares outstanding during the period and is calculated using the treasury stock method for stock incentive plans. Common equivalent shares are excluded from the computation in periods in which they have an anti-dilutive effect.
    The weighted average number of common shares used in the computation of basic and diluted earnings per share was as follows:

(3) Recent Accounting Pronouncements and Accounting Policies
Recently adopted accounting pronouncements:
    All accounting and reporting standards that became effective in 2026 were either not applicable to the Company or their adoption did not have a material impact on the Company.

6

Accounting and reporting standards that are not yet effective:

    In November 2024, the Financial Accounting Standards Board issued Accounting Standards Update 2024-03, Disaggregation of Income Statement Expenses, addressing investor requests for more transparent information. The guidance requires disclosure of specified information about certain costs and expenses in the notes to the financial statements. The guidance is effective for annual periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Prospective application is required, with retrospective application permitted. The Company will adopt this guidance for the year ended December 31, 2027 and the resulting impact will be disclosure only.
All other recently issued but not yet effective accounting and reporting standards are either not applicable to the Company or are not expected to have a material impact on the Company.

During the six months ended June 30, 2026, the Company increased the allowance for expected credit losses for available for sale securities primarily due to a decrease in the fair value of one investment in the asset-backed category. During the six months ended June 30, 2025, the Company decreased the allowance for expected credit losses for available for sale securities primarily due to improved pricing related to mortgage-backed securities.
The amortized cost and fair value of fixed maturity securities at June 30, 2026, by contractual maturity, are shown below. Actual maturities may differ from contractual maturities because certain issuers may have the right to call or prepay obligations.

(8) Arbitrage Trading Account
    At June 30, 2026 and December 31, 2025, the fair and carrying values of the arbitrage trading account were $1,292 million and $1,221 million, respectively. The primary focus of the trading account is merger arbitrage. Merger arbitrage is the business of investing in the securities of publicly held companies which are the targets in announced tender offers and mergers. Arbitrage investing differs from other types of investing in its focus on transactions and events believed likely to bring about a change in value over a relatively short time period (usually four months or less).
    The Company uses put options and call options in order to mitigate the impact of potential changes in market conditions on the merger arbitrage trading account. These options are reported at fair value. As of June 30, 2026, the fair value of long option contracts outstanding was $5 million (notional amount of $87 million) and the fair value of short option contracts was $7 million (notional amount of $88 million). Other than with respect to the use of these trading account securities, the Company does not make use of derivatives.

(10) Investment Funds
    The Company evaluates whether it is an investor in a variable interest entity ("VIE"). Such entities do not have sufficient equity at risk to finance their activities without additional subordinated financial support, or the equity investors, as a group, do not have the characteristics of a controlling financial interest (primary beneficiary). The Company determines whether it is the primary beneficiary of an entity subject to consolidation based on a qualitative assessment of the VIE's capital structure, contractual terms, nature of the VIE's operations and purpose, and the Company's relative exposure to the related risks of the VIE on the date it becomes initially involved in the VIE and on an ongoing basis. The Company is not the primary beneficiary in any of its investment funds, and accordingly, carries its interests in investment funds under the equity method of accounting.    
    The Company’s maximum exposure to loss with respect to these investments is limited to the carrying amount reported on the Company’s consolidated balance sheet and its unfunded commitments, which were $241 million as of June 30, 2026.

Other funds include deferred compensation trust assets of $51 million and $43 million as of June 30, 2026 and December 31, 2025, respectively. These assets support other liabilities reflected in the balance sheet of an equal amount for employees who have elected to defer a portion of their compensation. The change in the net asset value of the trust is recorded in other funds within net investment income with an offsetting equal amount within corporate expenses.

During the three and six months ended June 30, 2026, the Company reduced the allowance for expected credit losses due to the redemption of a loan. During the three and six months ended June 30, 2025, the Company reduced the allowance for expected credit losses due to the decrease in the weighted average life of the loan portfolio.
The Company monitors the performance of its loans receivable and assesses the ability of the borrower to pay principal and interest based upon loan structure, underlying property values, cash flow and related financial and operating performance of the property and market conditions.
    In evaluating the real estate loans, the Company considers their credit quality indicators, including loan to value ratios, which compare the outstanding loan amount to the estimated value of the property, the borrower’s financial condition and performance with respect to loan terms, the position in the capital structure, the overall leverage in the capital structure and other market conditions.

    Substantially all of the securities in an unrealized loss position are rated investment grade, except for the securities in the foreign government classification. A significant amount of the unrealized loss on foreign government securities is the result of changes in currency exchange rates. 
    A summary of the Company’s non-investment grade fixed maturity securities that were in an unrealized loss position at June 30, 2026 is presented in the table below:

For fixed maturity securities that management does not intend to sell or to be required to sell, the portion of the decline in value that is considered to be due to credit factors is recognized in earnings, and the portion of the decline in value that is considered to be due to non-credit factors is recognized in other comprehensive income (loss).
     The Company has evaluated its fixed maturity securities in an unrealized loss position and believes the unrealized losses are due primarily to temporary market and sector-related factors rather than to issuer-specific factors. None of these securities are delinquent or in default under financial covenants. Based on its assessment of these issuers, the Company expects them to continue to meet their contractual payment obligations as they become due.

(15) Fair Value Measurements
    The Company’s fixed maturity available for sale securities, equity securities and its arbitrage trading account securities are carried at fair value. Fair value is defined as “the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.” The Company utilizes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels, as follows:
Level 1 - Quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.
Level 2 - Quoted prices for similar assets or valuations based on inputs that are observable.
Level 3 - Estimates of fair value based on internal pricing methodologies using unobservable inputs. Unobservable inputs are only used to measure fair value to the extent that observable inputs are not available.
    Substantially all of the Company’s fixed maturity securities were priced by independent pricing services (generally one
U.S. pricing service plus additional pricing services with respect to a limited number of foreign securities held by the Company). The prices provided by the independent pricing services are estimated based on observable market data in active markets utilizing pricing models and processes, which may include benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers, sector groupings, matrix pricing and reference data. The pricing services may prioritize inputs differently on any given day for any security based on market conditions, and not all inputs are available for each security evaluation on any given day. The pricing services used by the Company have indicated that they will only produce an estimate of fair value if objectively verifiable information is available. The determination of whether markets are active or inactive is based upon the volume and level of activity for a particular asset class. The Company reviews the prices provided by pricing services for reasonableness and periodically performs independent price tests of a sample of securities to ensure proper valuation.
    If prices from independent pricing services are not available for fixed maturity securities, the Company estimates the fair value. For Level 2 securities, the Company utilizes pricing models and processes which may include benchmark yields, sector groupings, matrix pricing, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, bids, offers and reference data. Where broker quotes are used, the Company generally requests two or more quotes and sets a price within the range of quotes received based on its assessment of the credibility of the quote and its own evaluation of the security. The Company generally does not adjust quotes received from brokers. For securities traded only in private negotiations, the Company determines fair value based primarily on the cost of such securities, which is adjusted to reflect prices of recent placements of securities of the same issuer, financial projections, credit quality and business developments of the issuer and other relevant information.
    For Level 3 securities, the Company generally uses a discounted cash flow model to estimate the fair value of fixed maturity securities. The cash flow models are based upon assumptions as to prevailing credit spreads, interest rate and interest rate volatility, time to maturity and subordination levels. Projected cash flows are discounted at rates that are adjusted to reflect illiquidity, where appropriate.

(16) Reserves for Loss and Loss Expenses
    The Company's reserves for losses and loss expenses are comprised of case reserves and incurred but not reported liabilities ("IBNR"). When a claim is reported, a case reserve is established for the estimated ultimate payment based upon known information about the claim. As more information about the claim becomes available over time, case reserves are adjusted up or down as appropriate. Reserves are also established on an aggregate basis to provide for IBNR liabilities and expected loss reserve development on reported claims.
    Loss reserves included in the Company’s financial statements represent management’s best estimates based upon an actuarially derived point estimate and other considerations. The Company uses a variety of actuarial techniques and methods to derive an actuarial point estimate for each operating unit. These methods include paid loss development, incurred loss development, paid and incurred Bornhuetter-Ferguson methods and frequency and severity methods. In circumstances where one actuarial method is considered more credible than the others, that method is used to set the point estimate. The actuarial point estimate may also be based on a judgmental weighting of estimates produced from each of the methods considered. Industry loss experience is used to supplement the Company’s own data in selecting “tail factors” in areas where the Company’s own data is limited. The actuarial data is analyzed by line of business, coverage and accident or policy year, as appropriate, for each operating unit.
    The establishment of the actuarially derived loss reserve point estimate also includes consideration of qualitative factors that may affect the ultimate losses. These qualitative considerations include, among others, the impact of re-underwriting initiatives, changes in the mix of business, changes in distribution sources and changes in policy terms and conditions.
    The key assumptions used to arrive at the best estimate of loss reserves are the expected loss ratios, rate of loss cost inflation, and reported and paid loss emergence patterns. Expected loss ratios represent management’s expectation of losses at the time the business is priced and written, before any actual claims experience has emerged. This expectation is a significant determinant of the estimate of loss reserves for recently written business where there is little paid or incurred loss data to consider. Expected loss ratios are generally derived from historical loss ratios adjusted for the impact of rate changes, loss cost trends and known changes in the type of risks underwritten. Expected loss ratios are estimated for each key line of business within each operating unit. Expected loss cost inflation is particularly important for the long-tail lines, such as excess casualty, and claims with a high medical component, such as workers’ compensation. Reported and paid loss emergence patterns are used to project current reported or paid loss amounts to their ultimate settlement value. Loss development factors are based on the historical emergence patterns of paid and incurred losses, and are derived from the Company’s own experience and industry data. The paid loss emergence pattern is also significant to excess and assumed workers’ compensation reserves because those reserves are discounted to their estimated present value based upon such estimated payout patterns.
    Loss frequency and severity are measures of loss activity that are considered in determining the key assumptions described in our discussion of loss and loss expense reserves, including expected loss ratios, rate of loss cost inflation and reported and paid loss emergence patterns. Loss frequency is a measure of the number of claims per unit of insured exposure, and loss severity is a measure of the average size of claims. Factors affecting loss frequency include the effectiveness of loss controls and safety programs and changes in economic activity or weather patterns. Factors affecting loss severity include changes in policy limits, retentions, rate of inflation and judicial interpretations.
    Another factor affecting estimates of loss frequency and severity is the loss reporting lag, which is the period of time between the occurrence of a loss and the date the loss is reported to the Company. The length of the loss reporting lag affects our ability to accurately predict loss frequency (loss frequencies are more predictable for lines with short reporting lags) as well as the amount of reserves needed for incurred but not reported losses (less IBNR is required for lines with short reporting lags). As a result, loss reserves for lines with short reporting lags are likely to have less variation from initial loss estimates. For lines with short reporting lags, which include commercial automobile, primary workers’ compensation, other liability (claims-made) and property business, the key assumption is the loss emergence pattern used to project ultimate loss estimates from known losses paid or reported to date. For lines of business with long reporting lags, which include other liability (occurrence), products liability, excess workers’ compensation and liability reinsurance, the key assumption is the expected loss ratio since there is often little paid or incurred loss data to consider. Historically, the Company has experienced less variation from its initial loss estimates for lines of business with short reporting lags than for lines of business with long reporting lags.
    The key assumptions used in calculating the most recent estimate of the loss reserves are reviewed each quarter and adjusted, to the extent necessary, to reflect the latest reported loss data, current trends and other factors observed.

_______________________________________
(1) Claims occurring during the current year are net of loss reserve discounts of $33 million and $28 million for the six months ended June 30, 2026 and 2025, respectively.
(2) The change in estimates for claims occurring in prior years is net of loss reserve discount. On an undiscounted basis, the estimates for claims occurring in prior years increased by $11 million and $17 million for the six months ended June 30, 2026 and 2025, respectively.
(3) For certain retrospectively rated insurance policies and reinsurance agreements, reserve development is offset by additional or return premiums. Favorable development, net of additional and return premiums, was $3 million and $1 million for the six months ended June 30, 2026 and 2025.
During the six months ended June 30, 2026, favorable prior year development (net of additional and return premiums) of $3 million included $10 million of favorable prior year development for the Reinsurance & Monoline Excess segment partially offset by $7 million of adverse prior year development for the Insurance segment.
For the Insurance segment, the development during the six months of 2026 resulted primarily from favorable development for short tail-lines of business which was offset by adverse development for other liability and auto liability. The favorable development for short-tail lines of business during the six months of 2026 related to the 2025 accident year, and resulted from favorable settlements of both catastrophe and non-catastrophe property claims below our expectations.
The adverse other liability development was driven mainly by umbrella and excess liability claims, and to a lesser extent from the Company’s primary surplus lines casualty business. The other liability development was concentrated in accident years 2019 through 2023. The umbrella and excess liability development included a significant component stemming from underlying auto exposures. The Company believes that auto-related claims are being particularly impacted by social inflation, which is contributing to an increase in the frequency of large losses beyond expectations. An increase in the frequency of litigated claims is also driving up both indemnity and loss adjustment expense costs in these lines of business beyond expectations.
For the Reinsurance & Monoline Excess segment, the favorable development during the six months of 2026 was driven mainly by favorable development in non-proportional reinsurance assumed property, partially offset by adverse development in the non-proportional reinsurance assumed liability line of business. Similarly to the Insurance segment, the favorable property reinsurance development was driven by favorable claim settlements, below our expectations, related to the 2025 accident year. The unfavorable development for non-proportional reinsurance assumed liability was associated primarily with our U.S. assumed reinsurance businesses, and was concentrated mainly in accident years 2020 through 2023.
During the six months ended June 30, 2025, favorable prior year development (net of additional and return premiums) of $1 million included $20 million of favorable prior year development for the Reinsurance & Monoline Excess segment largely offset by $19 million of adverse prior year development for the Insurance segment.
For the Insurance segment, the adverse development during the first half of 2025 was driven by other liability and commercial auto liability and was partially offset by favorable development for short tail lines of business, including commercial property and commercial auto physical damage. The adverse other liability development was driven primarily by
22

umbrella and other claims attaching excess of primary policy limits and included a significant component stemming from underlying auto exposures. A secondary driver of the other liability development related to the Company’s excess and surplus lines casualty business. The other liability development was concentrated in accident years 2017 through 2022. The adverse commercial auto liability development was concentrated in accident years 2021 and 2022. The Company believes that auto-related claims are being particularly impacted by social inflation, which is contributing to an increase in the frequency of large losses beyond expectations. Social inflation can include higher settlement demands from plaintiffs, use of tactics such as litigation funding by the plaintiffs’ bar, negative public sentiment towards large businesses and corporations, and erosion of tort reforms, among others.
The favorable development for short tail property lines of business during the first half of 2025 related to the 2024 accident year, and resulted from favorable settlements of both catastrophe and non-catastrophe claims below our expectations.
For the Reinsurance & Monoline Excess segment, the favorable development during the first half of 2025 was driven mainly by favorable development in non-proportional reinsurance for assumed property. Similar to the Insurance segment, the favorable property reinsurance development was driven by favorable claim settlements, below our expectations, related mainly to the 2024 accident year.

(19) Restricted Stock Units
    Pursuant to its stock incentive plan, the Company may issue restricted stock units ("RSUs") to employees of the Company and its subsidiaries. The RSUs generally vest three to five years from the award date and are subject to other vesting and forfeiture provisions contained in the award agreement. RSUs are expensed pro-ratably over the vesting period. RSU expenses were $27 million and $25 million for the six months ended June 30, 2026 and 2025, respectively.

(20) Litigation and Contingent Liabilities
    In the ordinary course of business, the Company is subject to disputes, litigation and arbitration arising from its insurance and reinsurance businesses. These matters are generally related to insurance and reinsurance claims and are considered in the establishment of loss and loss expense reserves. In addition, the Company may also become involved in legal actions which seek extra-contractual damages, punitive damages or penalties, including claims alleging bad faith in handling of insurance claims. The Company expects its ultimate liability with respect to such matters will not be material to its financial condition. However, adverse outcomes on such matters are possible, from time to time, and could be material to the Company’s results of operations in any particular financial reporting period.
On December 22, 2023, one of the Company’s subsidiaries filed a lawsuit against certain reinsurers to recover in excess of $90 million in respect of certain losses paid to its policyholders under certain event cancellation and related insurance policies. On April 23, 2026, the court issued a judgment that principally resolved the lawsuit in favor of the Company's subsidiary. Certain reinsurers have filed applications requesting permission to appeal aspects of the judgment. The final amount recoverable by the Company’s subsidiary will be determined based upon the appellate process and additional costs due the Company’s subsidiary from reinsurers. The Company believes the final amount determined to be recoverable, in any case, will not be material to the Company’s financial condition.



(21) Leases
    Lessees are required to recognize a right-of-use asset and a lease liability for leases with terms of more than 12 months on the balance sheet. All leases disclosed within this footnote are classified as operating leases. Recognized right-of-use asset and lease liability are reported within other assets and other liabilities, respectively, in the consolidated balance sheet. Lease expense is reported in other operating costs and expenses in the consolidated statement of income and accounted for on a straight-line basis over the lease term.
    To determine the discount rate used to calculate the present value of future minimum lease payments, the Company uses its incremental borrowing rate during the lease commencement period in line with the respective lease duration. In certain cases, the Company has the option to renew the lease. Lease renewal future payments are included in the present value of the future minimum lease payments when the Company determines it is reasonably certain to renew.
The main leases entered into by the Company are for office space used by the Company’s businesses across the world. Additionally, the Company, to a lesser extent, has equipment leases mainly for office equipment.

The CODM assesses performance, makes decisions and allocates resources for each of the three reportable segments based on their contribution towards the Company's profitability and balance sheet strength. Certain key metrics such as combined ratio and return on allocated capital for the Insurance and Reinsurance & Monoline Excess segments, as well as Corporate segment expenditures, are examples of key components of the assessment, decision-making and resource-allocation process.
    The accounting policies of the segments are the same as those described in the summary of significant accounting policies. Income tax expense and benefits are calculated based upon the Company's overall effective tax rate.
    Summary financial information about the Company's reporting segments is presented in the following tables. Income (loss) before income taxes by segment includes allocated investment income. Identifiable assets by segment are those assets used in or allocated to the operation of each segment.

Item 2.     Management’s Discussion and Analysis of Financial Condition and Results of Operations

Overview
    W. R. Berkley Corporation is an insurance holding company that is among the largest commercial lines writers in the United States and operates worldwide in two segments of the property and casualty business: Insurance and Reinsurance & Monoline Excess. Our decentralized structure provides us with the flexibility to respond quickly and efficiently to local or specific market conditions and to pursue specialty business niches. It also allows us to be closer to our customers in order to better understand their individual needs and risk characteristics. While providing our businesses with certain operating autonomy, our structure allows us to capitalize on the benefits of economies of scale through centralized capital, investment, reinsurance, enterprise risk management, and actuarial, financial and corporate legal staff support. The Company’s primary sources of revenues and earnings are its insurance operations and its investments.
    An important part of our strategy is to form new businesses to capitalize on various market opportunities. Over the years, the Company has formed numerous businesses that are focused on important parts of the economy in the U.S., including healthcare, cyber security, energy and agriculture, and on growing international markets, including the Asia-Pacific region, South America and Mexico.
    The profitability of the Company’s insurance business is affected primarily by the adequacy of premium rates. The ultimate adequacy of premium rates is not known with certainty at the time an insurance policy is issued because premiums are determined before claims are reported. The ultimate adequacy of premium rates is affected mainly by the severity and frequency of claims, which are influenced by many factors, including natural and other disasters, regulatory measures and court decisions that define and change the extent of coverage and the effects of economic inflation on the amount of compensation for injuries or losses. General insurance prices are also influenced by available insurance capacity, i.e., the level of capital employed in the industry, and the industry’s willingness to deploy that capital.
    The Company’s profitability is also affected by its investment income and investment gains. The Company’s invested assets are invested principally in fixed maturity securities. The return on fixed maturity securities is affected primarily by general interest rates, as well as the credit quality and duration of the securities.
    The Company also invests in equity securities, merger arbitrage securities, investment funds, private equity, loans and real estate-related assets. The Company's investments in investment funds and its other alternative investments have experienced, and the Company expects to continue to experience, greater fluctuations in investment income. The Company's share of the earnings or losses from investment funds is generally reported on a one-quarter lag in order to facilitate the timely completion of the Company's consolidated financial statements.

Critical Accounting Estimates
    The following presents a discussion of accounting policies and estimates relating to reserves for losses and loss expenses, assumed premiums and allowance for expected credit losses and fair value measurements on investments. Management believes these policies and estimates are the most critical to its operations and require the most difficult, subjective and complex judgments.
    Reserves for Losses and Loss Expenses. To recognize liabilities for unpaid losses, either known or unknown, insurers establish reserves, which is a balance sheet account representing estimates of future amounts needed to pay claims and related expenses with respect to insured events which have occurred. Estimates and assumptions relating to reserves for losses and loss expenses are based on complex and subjective judgments, often including the interplay of specific uncertainties with related accounting and actuarial measurements. Such estimates are also susceptible to change as significant periods of time may elapse between the occurrence of an insured loss, the report of the loss to the insurer, the ultimate determination of the cost of the loss and the insurer’s payment of that loss.
    In general, when a claim is reported, claims personnel establish a “case reserve” for the estimated amount of the ultimate payment based upon known information about the claim at that time. The estimate represents an informed judgment based on general reserving practices and reflects the experience and knowledge of the claims personnel regarding the nature and value of the specific type of claim. Reserves are also established on an aggregate basis to provide for losses incurred but not reported (“IBNR”) to the insurer, potential inadequacy of case reserves and the estimated expenses of settling claims, including legal and other fees and general expenses of administrating the claims adjustment process. Reserves are established based upon the then current legal interpretation of coverage provided.
32

    In examining reserve adequacy, several factors are considered in estimating the ultimate economic value of losses. These factors include, among other things, historical data, legal developments, changes in social attitudes and economic conditions, including the effects of inflation. The actuarial process relies on the basic assumption that past experience, adjusted judgmentally for the effects of current developments and anticipated trends, is an appropriate basis for predicting future outcomes. Reserve amounts are based on management’s informed estimates and judgments using currently available data. As additional experience and other data become available and are reviewed, these estimates and judgments may be revised. This may result in reserve increases or decreases that would be reflected in our results in periods in which such estimates and assumptions are changed.
    Reserves do not represent an exact calculation of liability. Rather, reserves represent an estimate of what management expects the ultimate settlement and claim administration will cost. While the methods for establishing reserves are well tested over time, some of the major assumptions about anticipated loss emergence patterns are subject to uncertainty. These estimates, which generally involve actuarial projections, are based on management’s assessment of facts and circumstances then known, as well as estimates of trends in claims severity and frequency, judicial theories of liability and other factors, including the actions of third parties which are beyond the Company’s control. These variables are affected by external and internal events, such as inflation and economic volatility, judicial and litigation trends, reinsurance coverage, legislative changes and claim handling and reserving practices, which make it more difficult to accurately predict claim costs. The inherent uncertainties of estimating reserves are greater for certain types of liabilities where long periods of time elapse before a definitive determination of liability is made. Because setting reserves is inherently uncertain, the Company cannot provide assurance that its current reserves will prove adequate in light of subsequent events.
    Loss reserves included in the Company’s financial statements represent management’s best estimates based upon an actuarially derived point estimate and other considerations. The Company uses a variety of actuarial techniques and methods to derive an actuarial point estimate for each operating unit. These methods include paid loss development, incurred loss development, paid and incurred Bornhuetter-Ferguson methods and frequency and severity methods. In circumstances where one actuarial method is considered more credible than the others, that method is used to set the point estimate. For example, the paid loss and incurred loss development methods rely on historical paid and incurred loss data. For new lines of business, where there is insufficient history of paid and incurred claims data, or in circumstances where there have been significant changes in claim practices, the paid and incurred loss development methods would be less credible than other actuarial methods. The actuarial point estimate may also be based on a judgmental weighting of estimates produced from each of the methods considered. Industry loss experience is used to supplement the Company’s own data in selecting “tail factors” and in areas where the Company’s own data is limited. The actuarial data is analyzed by line of business, coverage and accident or policy year, as appropriate, for each operating unit.
    The establishment of the actuarially derived loss reserve point estimate also includes consideration of qualitative factors that may affect the ultimate losses. These qualitative considerations include, among others, the impact of re-underwriting initiatives, changes in the mix of business, changes in distribution sources and changes in policy terms and conditions. Examples of changes in terms and conditions that can have a significant impact on reserve levels are the use of aggregate policy limits, the expansion of coverage exclusions, whether or not defense costs are within policy limits, and changes in deductibles and attachment points.
    The key assumptions used to arrive at the best estimate of loss reserves are the expected loss ratios, rate of loss cost inflation, and reported and paid loss emergence patterns. Expected loss ratios represent management’s expectation of losses at the time the business is written, before any actual claims experience has emerged. This expectation is a significant determinant of the estimate of loss reserves for recently written business where there is little paid or incurred loss data to consider. Expected loss ratios are generally derived from historical loss ratios adjusted for the impact of rate changes, loss cost trends and known changes in the type of risks underwritten. Expected loss ratios are estimated for each key line of business within each operating unit. Expected loss cost inflation is particularly important for the long-tail lines, such as excess casualty, and claims with a high medical component, such as workers’ compensation. Reported and paid loss emergence patterns are used to project current reported or paid loss amounts to their ultimate settlement value. Loss development factors are based on the historical emergence patterns of paid and incurred losses, and are derived from the Company’s own experience and industry data. The paid loss emergence pattern is also significant to excess and assumed workers’ compensation reserves because those reserves are discounted to their estimated present value based upon such estimated payout patterns. Management believes the estimates and assumptions it makes in the reserving process provide the best estimate of the ultimate cost of settling claims and related expenses with respect to insured events which have occurred; however, different assumptions and variables could lead to significantly different reserve estimates.
33

    Loss frequency and severity are measures of loss activity that are considered in determining the key assumptions described in our discussion of loss and loss expense reserves, including expected loss ratios, rate of loss cost inflation and reported and paid loss emergence patterns. Loss frequency is a measure of the number of claims per unit of insured exposure, and loss severity is a measure of the average size of claims. Factors affecting loss frequency include the effectiveness of loss controls and safety programs and changes in economic activity or weather patterns. Factors affecting loss severity include changes in policy limits, retentions, rate of inflation and judicial interpretations.
    Another factor affecting estimates of loss frequency and severity is the loss reporting lag, which is the period of time between the occurrence of a loss and the date the loss is reported to the Company. The length of the loss reporting lag affects our ability to accurately predict loss frequency (loss frequencies are more predictable for lines with short reporting lags) as well as the amount of reserves needed for incurred but not reported losses (less IBNR is required for lines with short reporting lags). As a result, loss reserves for lines with short reporting lags are likely to have less variation from initial loss estimates. For lines with short reporting lags, which include commercial automobile, primary workers’ compensation, other liability (claims-made) and property business, the key assumption is the loss emergence pattern used to project ultimate loss estimates from known losses paid or reported to date. For lines of business with long reporting lags, which include other liability (occurrence), products liability, excess workers’ compensation and liability reinsurance, the key assumption is the expected loss ratio since there is often little paid or incurred loss data to consider. Historically, the Company has experienced less variation from its initial loss estimates for lines of business with short reporting lags than for lines of business with long reporting lags.
    The key assumptions used in calculating the most recent estimate of the loss reserves are reviewed each quarter and adjusted, to the extent necessary, to reflect the latest reported loss data, current trends and other factors observed. If the actual level of loss frequency and severity are higher or lower than expected, the ultimate losses will be different than management’s estimate. The following table reflects the impact of changes (which could be favorable or unfavorable) in frequency and severity, relative to our assumptions, on our loss estimate for claims occurring in 2025:
(In thousands)Frequency (+/-)
Severity (+/-)1%5%10%
1%$154,823 $466,010 $854,993 
5%466,010 789,520 1,193,909 
10%854,993 1,193,909 1,617,554 
    Our net reserves for losses and loss expenses of approximately $20 billion as of June 30, 2026 relate to multiple accident years. Therefore, the impact of changes in frequency or severity for more than one accident year could be higher or lower than the amounts reflected above. The impact of such changes would likely be manifested gradually over the course of many years, as the magnitude of the changes became evident.
    Approximately $3.4 billion, or 17.3%, of the Company’s net loss reserves as of June 30, 2026 relate to the Reinsurance & Monoline Excess segment. There is a higher degree of uncertainty and greater variability regarding estimates of excess workers' compensation and assumed reinsurance loss reserves, which predominantly comprise these reserves. In the case of excess workers’ compensation, our policies generally attach at $1 million or higher. The claims which reach our layer therefore tend to involve the most serious injuries and many remain open for the lifetime of the claimant, which extends the claim settlement tail. These claims also occur less frequently but tend to be larger than primary claims, which increases claim variability. In the case of assumed reinsurance, our loss reserve estimates are based, in part, upon information received from ceding companies. If information received from ceding companies is not timely or correct, the Company’s estimate of ultimate losses may not be accurate. Furthermore, due to delayed reporting of claim information by ceding companies, the claim settlement tail for assumed reinsurance is also extended. Management considers the impact of delayed reporting and the extended tail in its selection of loss development factors for these lines of business.
    Information received from ceding companies is used to set initial expected loss ratios, to establish case reserves and to estimate reserves for incurred but not reported losses on assumed reinsurance business. This information, which is generally provided through reinsurance intermediaries, is gathered through the underwriting process and from periodic claim reports and other correspondence with ceding companies. The Company performs underwriting and claim audits of selected ceding companies to determine the accuracy and completeness of information provided to the Company. The information received from the ceding companies is supplemented by the Company’s own loss development experience with similar lines of business as well as industry loss trends and loss development benchmarks.

___________
(1) Reserves for workers’ compensation and Reinsurance & Monoline Excess are net of an aggregate net discount of $434 million and $420 million as of June 30, 2026 and December 31, 2025, respectively.
(2) Short-tail lines include commercial multi-peril (non-liability), inland marine, accident and health, fidelity and surety, boiler and machinery, high net worth homeowners and other lines.
(3) Reinsurance & Monoline Excess includes property and casualty reinsurance, as well as operations that solely retain risk on an excess basis and certain program management business.
    The Company evaluates reserves for losses and loss adjustment expenses on a quarterly basis. Changes in estimates of prior year losses are reported when such changes are made. The changes in prior year loss reserve estimates are generally the result of ongoing analysis of recent loss development trends. Original estimates are increased or decreased as additional information becomes known regarding individual claims and aggregate claim trends.
    Certain of the Company's insurance and reinsurance contracts are retrospectively rated, whereby the Company collects more or less premiums based on the level of loss activity. For those contracts, changes in loss and loss adjustment expenses for prior years may be fully or partially offset by additional or return premiums.
    Net prior year development (i.e., the sum of prior year reserve changes and prior year earned premiums changes) for the six months ended June 30, 2026 and 2025 are as follows:

Net favorable prior year development$2,685 $1,483 
During the six months ended June 30, 2026, favorable prior year development (net of additional and return premiums) of $3 million included $10 million of favorable prior year development for the Reinsurance & Monoline Excess segment partially offset by $7 million of adverse prior year development for the Insurance segment.
For the Insurance segment, the development during the six months of 2026 resulted primarily from favorable development for short tail-lines of business which was offset by adverse development for other liability and auto liability. The favorable development for short-tail lines of business during the six months of 2026 related to the 2025 accident year, and resulted from favorable settlements of both catastrophe and non-catastrophe property claims below our expectations.
The adverse other liability development was driven mainly by umbrella and excess liability claims, and to a lesser extent from the Company’s primary surplus lines casualty business. The other liability development was concentrated in accident years 2019 through 2023. The umbrella and excess liability development included a significant component stemming from underlying auto exposures. The Company believes that auto-related claims are being particularly impacted by social inflation, which is contributing to an increase in the frequency of large losses beyond expectations. An increase in the frequency of litigated claims is also driving up both indemnity and loss adjustment expense costs in these lines of business beyond expectations.
For the Reinsurance & Monoline Excess segment, the favorable development during the six months of 2026 was driven mainly by favorable development in non-proportional reinsurance assumed property, partially offset by adverse development in the non-proportional reinsurance assumed liability line of business. Similarly to the Insurance segment, the favorable property reinsurance development was driven by favorable claim settlements, below our expectations, related to the 2025 accident year. The unfavorable development for non-proportional reinsurance assumed liability was associated primarily with our U.S. assumed reinsurance businesses, and was concentrated mainly in accident years 2020 through 2023.
During the six months ended June 30, 2025, favorable prior year development (net of additional and return premiums) of $1 million included $20 million of favorable prior year development for the Reinsurance & Monoline Excess segment largely offset by $19 million of adverse prior year development for the Insurance segment.
For the Insurance segment, the adverse development during the first half of 2025 was driven by other liability and commercial auto liability and was partially offset by favorable development for short tail lines of business, including commercial property and commercial auto physical damage. The adverse other liability development was driven primarily by umbrella and other claims attaching excess of primary policy limits and included a significant component stemming from underlying auto exposures. A secondary driver of the other liability development related to the Company’s excess and surplus lines casualty business. The other liability development was concentrated in accident years 2017 through 2022. The adverse commercial auto liability development was concentrated in accident years 2021 and 2022. The Company believes that auto-related claims are being particularly impacted by social inflation, which is contributing to an increase in the frequency of large losses beyond expectations. Social inflation can include higher settlement demands from plaintiffs, use of tactics such as litigation funding by the plaintiffs’ bar, negative public sentiment towards large businesses and corporations, and erosion of tort reforms, among others.
The favorable development for short tail property lines of business during the first half of 2025 related to the 2024 accident year, and resulted from favorable settlements of both catastrophe and non-catastrophe claims below our expectations.
For the Reinsurance & Monoline Excess segment, the favorable development during the first half of 2025 was driven mainly by favorable development in non-proportional reinsurance for assumed property. Similar to the Insurance segment, the favorable property reinsurance development was driven by favorable claim settlements, below our expectations, related mainly to the 2024 accident year.
Reserve Discount. The Company discounts its liabilities for certain workers’ compensation reserves. The amount of workers’ compensation reserves that were discounted was $1,436 million and $1,400 million at June 30, 2026 and December 31, 2025, respectively. The aggregate net discount for those reserves, after reflecting the effects of ceded reinsurance, was $434 million and $420 million at June 30, 2026 and December 31, 2025, respectively. At June 30, 2026, discount rates by year ranged from 0.7% to 6.5%, with a weighted average discount rate of 3.6%.
    Substantially all of the workers’ compensation discount (97% of total discounted reserves at June 30, 2026) relates to excess workers’ compensation reserves. In order to properly match loss expenses with income earned on investment securities supporting the liabilities, reserves for excess workers’ compensation business are discounted using risk-free discount rates
36

determined by reference to the U.S. Treasury yield curve. These rates are determined annually based on the weighted average rate for the period. Once established, no adjustments are made to the discount rate for that period, and any increases or decreases in loss reserves in subsequent years are discounted at the same rate, without regard to when any such adjustments are recognized. The expected loss and loss expense payout patterns subject to discounting are derived from the Company’s loss payout experience.
    The Company also discounts reserves for certain other long-duration workers’ compensation reserves (representing approximately 3% of total discounted reserves at June 30, 2026), including reserves for quota share reinsurance and reserves related to losses regarding occupational lung disease. These reserves are discounted at statutory rates permitted by the Department of Insurance of the State of Delaware.
    Assumed Reinsurance Premiums. The Company estimates the amount of assumed reinsurance premiums that it will receive under treaty reinsurance agreements at the inception of the contracts. These premium estimates are revised as the actual amount of assumed premiums is reported to the Company by the ceding companies. As estimates of assumed premiums are made or revised, the related amount of earned premiums, commissions and incurred losses associated with those premiums are recorded. Estimated assumed premiums receivable were approximately $48 million at June 30, 2026 and $54 million at December 31, 2025. The assumed premium estimates are based upon terms set forth in reinsurance agreements, information received from ceding companies during the underwriting and negotiation of agreements, reports received from ceding companies and discussions and correspondence with reinsurance intermediaries. The Company also considers its own view of market conditions, economic trends and experience with similar lines of business. These premium estimates represent management’s best estimate of the ultimate amount of premiums to be received under its assumed reinsurance agreements.
    Allowance for Expected Credit Losses on Investments.
    Fixed Maturity Securities – For fixed maturity securities in an unrealized loss position where the Company intends to sell, or it is more likely than not that it will be required to sell the security before recovery in value, the amortized cost basis is written down to fair value through net investment gains (losses). For fixed maturity securities in an unrealized loss position where the Company does not intend to sell, or it is more likely than not that it will not be required to sell the security before recovery in value, the Company evaluates whether the decline in fair value has resulted from credit losses or all other factors (non-credit factors). In making this assessment, the Company considers the extent to which fair value is less than amortized cost, changes to the rating of the security by a rating agency, and adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, an allowance for expected credit losses is recorded for the credit loss through net investment gains (losses), limited by the amount that the fair value is less than the amortized cost basis. The allowance is adjusted for any change in expected credit losses and subsequent recoveries through net investment gains (losses). The impairment related to non-credit factors is recognized in other comprehensive income (loss).
    The Company’s credit assessment of allowance for expected credit losses uses a third party model for available for sale and held to maturity securities, as well as loans receivable. The allowance for expected credit losses is generally based on the performance of the underlying collateral under various economic and default scenarios that involve subjective judgments and estimates by management. Modeling these securities involves various factors, such as projected default rates, the nature and realizable value of the collateral, if any, the ability of the issuer to make scheduled payments, historical performance and other relevant economic and performance factors. A discounted cash flow analysis is used to ascertain the amount of the allowance for expected credit losses, if any. In general, the model reverts to the rating-level long-term average marginal default rates based on 10 years of historical data, beyond the forecast period. For other inputs, the model in most cases reverts to the baseline long-term assumptions linearly over five years beyond the forecast period. The long-term assumptions are based on the historical averages.
    The Company classifies its fixed maturity securities by credit rating, primarily based on ratings assigned by credit rating agencies. For purposes of classifying securities with different ratings, the Company uses the average of the credit ratings assigned, unless in limited situations the Company’s own analysis indicates an internal rating is more appropriate. Securities that are not rated by a rating agency are evaluated and classified by the Company on a case-by-case basis.

    A summary of the Company’s non-investment grade fixed maturity securities that were in an unrealized loss position at June 30, 2026 is presented in the table below:
($ in thousands)Number of
Securities
Aggregate
Fair Value
 Gross Unrealized Loss
Foreign government (1)56 $167,337 $172,029

Mortgage-backed13 1,524 122 
Total77 $186,437 $173,301 
(1) A significant amount of the unrealized loss is the result of changes in currency exchange rates.
    As of June 30, 2026, the Company recorded an allowance for expected credit losses on fixed maturity securities of $0.4 million. The Company has evaluated the remaining fixed maturity securities in an unrealized loss position and believes the unrealized losses are due primarily to temporary market and sector-related factors rather than to issuer-specific factors. None of these securities are delinquent or in default under financial covenants. Based on its assessment of these issuers, the Company expects them to continue to meet their contractual payment obligations as they become due.
Loans Receivable – For loans receivable, the Company estimates an allowance for expected credit losses based on relevant information about past events, including historical loss experience, current conditions and forecasts that affect the expected collectability of the amortized cost of the financial asset. The allowance for expected credit losses is presented as a reduction to amortized cost of the financial asset in the consolidated balance sheet and changes to the estimate for expected credit losses are recognized through net investment gains (losses). Loans receivable are reported net of an allowance for expected credit losses of none and $0.2 million as of June 30, 2026 and December 31, 2025, respectively.
    Fair Value Measurements.
The Company’s fixed maturity available for sale securities, equity securities, and its arbitrage trading account securities are carried at fair value. Fair value is defined as “the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.” The Company utilizes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable for similar assets in active markets. Level 3 inputs are unobservable inputs for the asset or liability. Unobservable inputs may only be used to measure fair value to the extent that observable inputs are not available. The fair value of the vast majority of the Company’s portfolio is based on observable data (other than quoted prices) and, accordingly, is classified as Level 2.
    In classifying particular financial securities in the fair value hierarchy, the Company uses its judgment to determine whether the market for a security is active and whether significant pricing inputs are observable. The Company determines the existence of an active market by assessing whether transactions occur with sufficient frequency and volume to provide reliable pricing information. The Company determines whether inputs are observable based on the use of such information by pricing services and external investment managers, the uninterrupted availability of such inputs, the need to make significant adjustments to such inputs and the volatility of such inputs over time. If the market for a security is determined to be inactive or if significant inputs used to price a security are determined to be unobservable, the security is categorized in Level 3 of the fair value hierarchy.
    Because many fixed maturity securities do not trade on a daily basis, the Company utilizes pricing models and processes which may include benchmark curves, benchmarking of like securities, sector groupings and matrix pricing. Market inputs used to evaluate securities include benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers and reference data. Quoted prices are often unavailable for recently issued securities that are infrequently traded or securities that are only traded in private transactions. For publicly traded securities for which quoted prices are unavailable, the Company determines fair value based on independent broker quotations and other observable market data. For securities traded only in private negotiations, the Company determines fair value based primarily on the cost of such securities, which is adjusted to reflect prices of recent placements of securities of the same issuer, financial data, projections and business developments of the issuer and other relevant information.

    Independent pricing services – Substantially all of the Company’s fixed maturity securities available for sale were priced by independent pricing services (generally one U.S. pricing service plus additional pricing services with respect to a limited number of foreign securities held by the Company). The prices provided by the independent pricing services are generally based on observable market data in active markets (e.g., broker quotes and prices observed for comparable securities). The determination of whether markets are active or inactive is based upon the volume and level of activity for a particular asset class. The Company reviews the prices provided by pricing services for reasonableness based upon current trading levels for similar securities. If the prices appear unusual to the Company, they are re-examined and the value is either confirmed or revised. In addition, the Company periodically performs independent price tests of a sample of securities to ensure proper valuation and to verify our understanding of how securities are priced. Based upon the Company’s review of the methodologies used by the independent pricing services, these securities were classified as Level 2.
    Syndicate manager – The Company has a 15% participation in a Lloyd’s syndicate, and the Company’s share of the securities owned by the syndicate is priced by the syndicate’s manager. The majority of the securities are liquid, short duration fixed maturity securities. The Company reviews the syndicate manager’s pricing methodology and audited financial statements and holds discussions with the syndicate manager as necessary to confirm its understanding and agreement with security prices. Based upon the Company’s review of the methodologies used by the syndicate manager, these securities were classified as Level 2.
    Observable data – If independent pricing is not available, the Company prices the securities directly. Prices are based on observable market data where available, including current trading levels for similar securities and non-binding quotations from brokers. The Company generally requests two or more quotes. If more than one quote is received, the Company sets a price within the range of quotes received based on its assessment of the credibility of the quote and its own evaluation of the security. The Company generally does not adjust quotes obtained from brokers. Since these securities were priced based on observable data, they were classified as Level 2.
    Cash flow model – If the above methodologies are not available, the Company prices securities using a discounted cash flow model based upon assumptions as to prevailing credit spreads, interest rates and interest rate volatility, time to maturity and subordination levels. Discount rates are adjusted to reflect illiquidity where appropriate. These securities were classified as Level 3.

    Net Income to Common Stockholders. The following table presents the Company’s net income to common stockholders and net income per diluted share for the six months ended June 30, 2026 and 2025:
(In thousands, except per share data)20262025
Net income to common stockholders$967,478 $818,860 
Weighted average diluted shares393,316 400,098 
Net income per diluted share$2.46 $2.05 
    The Company reported net income to common stockholders of $967 million in 2026 compared to $819 million in 2025. The $148 million increase in net income was primarily due to an after-tax increase in foreign currency gains of $73 million due to the U.S. dollar strengthening against other major currencies in 2026, an after-tax increase of $68 million in net investment income primarily due to a larger fixed maturity securities portfolio and increased investment income from investment funds, an after-tax increase in underwriting income of $60 million mainly due to lower catastrophe losses in 2026, a $43 million decrease in tax expense due to the repeal of undiscounted property-casualty loss deductions and special estimated payments formerly available under Internal Revenue Code Section 847, partially offset by deferred tax charges in the United Kingdom and an after-tax increase in profits from non-insurance businesses of $19 million, partially offset by an after-tax increase in net investment losses of $96 million mainly due to a change in unrealized gains on equity securities, an after-tax increase in corporate expenses of $14 million, an after-tax decrease of $3 million in profit from insurance service businesses and an after-tax decrease in income of $2 million related to minority interest. The number of weighted average diluted shares decreased 6.8 million for 2026 compared to 2025, mainly reflecting shares repurchased in 2026 and 2025.
    Premiums. Gross premiums written were $7,930 million in 2026, an increase of 3.5% from $7,662 million in 2025. The increase was due to a $341 million increase in the Insurance segment, partially offset by a $73 million decrease in the
40

Reinsurance & Monoline Excess segment. Approximately 81% of premiums expiring in 2026, and 80% of premiums expiring in 2025 were renewed.
    Average renewal premium rates (per unit of exposure) for insurance and facultative reinsurance increased 5.1% in 2026 and increased 5.6% excluding workers' compensation.
    A summary of gross premiums written in 2026 compared with 2025 by line of business within each business segment follows:
Insurance - gross premiums increased 5% to $7,165 million in 2026 from $6,824 million in 2025. Gross premiums increased $171 million (9%) for short-tail lines, $71 million (10%) for professional liability, $68 million (3%) for other liability and $34 million (4%) for auto, partially offset by a reduction of $3 million (1%) for workers' compensation.
Reinsurance & Monoline Excess - gross premiums decreased by 9% to $765 million in 2026 from $838 million in 2025. Gross premiums decreased $49 million (13%) for casualty and $32 million (11%) for property, partially offset by an increase of $8 million (5%) for monoline excess.
    Net premiums written were $6,605 million in 2026, an increase of 2% from $6,485 million in 2025. Ceded reinsurance premiums as a percentage of gross written premiums were 17% and 15% in 2026 and 2025, respectively.
    Premiums earned increased 3% to $6,303 million in 2026 from $6,111 million in 2025. Insurance premiums (including the impact of rate changes) are generally earned evenly over the policy term, and accordingly, recent rate increases will be earned over the upcoming quarters. Premiums earned in 2026 are related to business written during both 2026 and 2025. Audit premiums were $139 million in 2026 compared with $168 million in 2025.
    Net Investment Income. Following is a summary of net investment income for the six months ended June 30, 2026 and 2025:

Total$823,048 $739,595 4.9 %4.8 %
    Net investment income increased 11% to $823 million in 2026 from $740 million in 2025 due primarily to a $71 million increase in income from fixed maturity securities mainly driven by a larger fixed maturity securities portfolio, a $14 million increase in income from investment funds primarily due to energy funds and real estate funds and an $11 million increase in equity securities, partially offset by an $11 million decrease in arbitrage trading account, a $1 million decrease in real estate and a $1 million increase in investment expenses. Investment funds are reported on a one quarter lag. The average annualized yield for fixed maturity securities was 5.0% in 2026 and 4.9% in 2025. The effective duration of the fixed maturity portfolio was 3.2 years at June 30, 2026 and 3.0 years at December 31, 2025. Average invested assets, at cost (including cash and cash equivalents), were $33.5 billion in 2026, up 8% from $30.9 billion in 2025.
    Insurance Service Fees. The Company earns fees from an insurance distribution business, a third-party administrator and as a servicing carrier of workers' compensation assigned risk plans for certain states. Insurance service fees were $59 million in 2026 compared to $62 million in 2025.
    Net Realized and Unrealized Gains (Losses) on Investments. The Company buys and sells securities and other investment assets on a regular basis in order to maximize its total return on investments. Decisions to sell securities and other investment assets are based on management’s view of the underlying fundamentals of specific investments as well as management’s expectations regarding interest rates, credit spreads, currency values and general economic conditions. Net realized and unrealized losses on investments were $71 million in 2026 compared with gains of $46 million in 2025. The losses
41

of $71 million in 2026 reflected net realized losses on investments of $48 million and a decrease in unrealized gains on equity securities of $23 million. The gains of $46 million in 2025 reflected an increase in unrealized gains on equity securities of $83 million, partially offset by net realized losses on investments of $37 million.
Change in Allowance for Expected Credit Losses on Investments. Based on credit factors, the allowance for expected credit losses is increased or decreased depending on the percentage of unrealized loss relative to amortized cost by security, changes in rating of the security by a rating agency, and adverse conditions specifically related to the security, among other factors. The pre-tax change in allowance for expected credit losses on investments, which are reflected in net investment gains (losses), increased by $0.2 million ($0.2 million after-tax) in 2026 due to a decrease in fair value of one investment in fixed maturity securities, and decreased by $1 million ($0.8 million after-tax) in 2025 reflecting improved pricing related to fixed maturity securities and the redemption of one loan in the loan receivable portfolio.
Revenues from Non-Insurance Businesses. Revenues from non-insurance businesses were derived from businesses engaged in the distribution of promotional merchandise, world-wide textile solutions and aviation-related businesses that provide services to aviation markets, including (i) the distribution, manufacturing, repair and overhaul of aircraft parts and components, (ii) the sale of new and used aircraft, and (iii) avionics, fuel, maintenance, storage and charter services. Revenues from non-insurance businesses were $291 million in 2026 and $258 million in 2025. The increase mainly relates to aviation-related business due to plane sales, partially offset by the reduction in commercial and residential textile business and promotional merchandise business.
    Losses and Loss Expenses. Losses and loss expenses increased to $3,897 million in 2026 from $3,856 million in 2025. The consolidated loss ratio was 61.8% in 2026 and 63.1% in 2025. Catastrophe losses, net of reinsurance recoveries, were $138 million in 2026 primarily related to winter storms, compared to $210 million in 2025 with the largest contributors being California wildfire losses and frequency of severe storms. Favorable prior year reserve development (net of premium offsets) was $3 million in 2026 and $1 million in 2025.

Other Operating Costs and Expenses. Following is a summary of other operating costs and expenses for the six months ended June 30, 2026 and 2025:
($ in thousands)20262025
Policy acquisition and insurance operating expenses$1,798,528 $1,720,345 
Insurance service expenses48,634 47,534 
Net foreign currency (gains) losses(15,037)74,774 
Other costs and expenses164,454 $146,564 
Total$1,996,579 $1,989,217 
    Policy acquisition and insurance operating expenses are comprised of commissions paid to agents and brokers, premium taxes and other assessments and internal underwriting costs. Policy acquisition and insurance operating expenses increased 5% and net premiums earned increased 3% from 2025. The expense ratio (underwriting expenses expressed as a percentage of net premiums earned) increased 0.4 points to 28.6% in 2026 from 28.2% in 2025, mainly due to investments in the business and from the decline in net earned premiums related to the Reinsurance & Monoline Excess segment.
    Insurance service expenses, which represent the costs associated with the fee-based businesses, were $49 million in 2026 and $48 million in 2025.
42

    Net foreign currency (gains) losses result from transactions denominated in a currency other than a company's operating functional currency. Net foreign currency gains were $15 million in 2026 compared to losses of $75 million in 2025, primarily due to the U.S. dollar strengthening against other major currencies in 2026.
    Other costs and expenses represent general and administrative expenses of the parent company and other expenses not allocated to business segments, including the cost of certain long-term incentive plans and new business ventures. Other costs and expenses increased to $164 million in 2026 from $147 million in 2025, primarily due to higher compensation-related costs and new start-up operating unit expenses in 2026.
    Expenses from Non-Insurance Businesses. Expenses from non-insurance businesses represent costs associated with businesses engaged in the distribution of promotional merchandise, world-wide textile solutions and aviation-related businesses that include (i) cost of goods sold related to aircraft and products sold and services provided, and (ii) general and administrative expenses. Expenses from non-insurance businesses were $259 million in 2026 compared to $249 million in 2025. The increase mainly relates to aviation-related business, partially offset by the reduction in commercial and residential textile business and promotional merchandise business.
Interest Expense. Interest expense was $63 million in both 2026 and 2025.
Income Taxes. The effective income tax rate was 18.8% and 22.9% for the six months ended June 30, 2026 and 2025, respectively. The lower effective income tax rate for the six months ended June 30, 2026, as compared to the earlier period, was primarily due to the impact of the repeal of undiscounted property-casualty loss deductions and special estimated payments formerly available under Internal Revenue Code Section 847, partially offset by deferred tax charges in the United Kingdom.
    The Company has not provided U.S. deferred income taxes on the undistributed earnings of approximately $652 million of its non-U.S. subsidiaries, since these earnings are intended to be permanently reinvested in the non-U.S. subsidiaries. In the future, if such earnings were distributed, the Company projects that the incremental tax, if any, will not be material.
In the United States, on July 4, 2025, the budget reconciliation package known as the “One Big Beautiful Bill Act” was signed into law. Changes resulting from the tax provisions thereunder did not have a material impact on the Company’s results from operations.

    Net Income to Common Stockholders. The following table presents the Company’s net income to common stockholders and net income per diluted share for the three months ended June 30, 2026 and 2025:
(In thousands, except per share data)20262025
Net income to common stockholders$452,261 $401,288 
Weighted average diluted shares391,804 400,368 
Net income per diluted share$1.15 $1.00 
    The Company reported net income to common stockholders of $452 million in 2026 compared to $401 million in 2025. The $51 million increase in net income was primarily due to an after-tax increase in underwriting income of $45 million due to lower catastrophe losses in 2026, an after-tax decrease in foreign currency losses of $42 million due to the U.S. dollar weakening against other major currencies in 2026 to a lesser degree, an after-tax increase of $31 million in net investment income primarily due to a larger fixed maturity securities portfolio, a $10 million decrease in tax expense due to a change in the effective tax rate and an after-tax increase in profits from non-insurance businesses of $4 million, partially offset by an after-tax increase in net investment losses of $68 million mainly due to change in unrealized gains on equity securities, an after-tax increase in corporate expenses of $10 million and an after-tax decrease of $3 million in profit from insurance service businesses. The number of weighted average diluted shares decreased 8.6 million for 2026 compared to 2025, mainly reflecting shares repurchased in 2026 and 2025.
    Premiums. Gross premiums written were $4,144 million in 2026, an increase of 4% from $3,978 million in 2025. The increase was due to a $196 million increase in the Insurance segment, partially offset by a $30 million decrease in the Reinsurance & Monoline Excess segment. Approximately 81% of premiums expiring in 2026, and 80% of premiums expiring in 2025 were renewed.

    Average renewal premium rates (per unit of exposure) for insurance and facultative reinsurance increased 3.5% in 2026 and increased 3.8% excluding workers' compensation.
    A summary of gross premiums written in 2026 compared with 2025 by line of business within each business segment follows:
Insurance - gross premiums increased 5% to $3,803 million in 2026 from $3,607 million in 2025. Gross premiums increased $96 million (10%) for short-tail lines, $47 million (12%) for professional liability, $37 million (3%) for other liability, $10 million (2%) for auto and $6 million (2%) for workers' compensation.
Reinsurance & Monoline Excess - gross premiums decreased by 8% to $341 million in 2026 from $371 million in 2025. Gross premiums decreased $25 million (13%) for casualty and $6 million (4%) for property, partially offset by an increase of $1 million (3%) for monoline excess.
    Net premiums written were $3,430 million in 2026, an increase of 2.4% from $3,351 million in 2025. Ceded reinsurance premiums as a percentage of gross written premiums was 17% and 16% in 2026 and 2025, respectively.
    Premiums earned increased 3% to $3,187 million in 2026 from $3,098 million in 2025. Insurance premiums (including the impact of rate changes) are generally earned evenly over the policy term, and accordingly, recent rate increases will be earned over the upcoming quarters. Premiums earned in 2026 are related to business written during both 2026 and 2025. Audit premiums were $65 million in 2026 compared with $86 million in 2025.
    Net Investment Income. Following is a summary of net investment income for the three months ended June 30, 2026 and 2025:

Investment expenses(4,473)(2,548)— — 
Total$418,714 $379,303 5.0 %4.9 %
    Net investment income increased 10% to $419 million in 2026 from $379 million in 2025 due primarily to a $38 million increase in income from fixed maturity securities mainly driven by a larger fixed maturity securities portfolio, a $6 million increase in equity securities, a $2 million increase in income from investment funds and a $1 million decrease in loss from real estate, partially offset by a $5 million decrease in arbitrage trading account and a $2 million increase in investment expenses. Investment funds are reported on a one quarter lag. The average annualized yield for fixed maturity securities was 5.0% in 2026 and 4.9% in 2025. The effective duration of the fixed maturity portfolio was 3.2 years at June 30, 2026 and 3.0 years at December 31, 2025. Average invested assets, at cost (including cash and cash equivalents), were $33.8 billion in 2026, up 8% from $31.2 billion in 2025.
    Insurance Service Fees. The Company earns fees from an insurance distribution business, a third-party administrator and as a servicing carrier of workers' compensation assigned risk plans for certain states. Insurance service fees were $31 million in 2026 compared to $33 million in 2025.
    Net Realized and Unrealized Gains (Losses) on Investments. The Company buys and sells securities and other investment assets on a regular basis in order to maximize its total return on investments. Decisions to sell securities and other investment assets are based on management’s view of the underlying fundamentals of specific investments as well as management’s expectations regarding interest rates, credit spreads, currency values and general economic conditions. Net realized and unrealized losses on investments were $55 million in 2026 compared with gains of $31 million in 2025. The losses of $55 million in 2026 reflected net realized losses on investments of $37 million and a decrease in unrealized gains on equity securities of $18 million. The gains of $31 million in 2025 reflected an increase in unrealized gains on equity securities of $64 million, partially offset by net realized losses on investments of $33 million.
45

Change in Allowance for Expected Credit Losses on Investments. Based on credit factors, the allowance for expected credit losses is increased or decreased depending on the percentage of unrealized loss relative to amortized cost by security, changes in rating of the security by a rating agency, and adverse conditions specifically related to the security, among other factors. The pre-tax change in allowance for expected credit losses on investments, which are reflected in net investment gains (losses), increased by $59 thousand ($47 thousand after-tax) in 2026, and decreased by $0.4 million ($0.3 million after-tax) in 2025.
Revenues from Non-Insurance Businesses. Revenues from non-insurance businesses were derived from businesses engaged in the distribution of promotional merchandise, world-wide textile solutions and aviation-related businesses that provide services to aviation markets, including (i) the distribution, manufacturing, repair and overhaul of aircraft parts and components, (ii) the sale of new and used aircraft, and (iii) avionics, fuel, maintenance, storage and charter services. Revenues from non-insurance businesses were $134 million in 2026 and $129 million in 2025. The increase mainly relates to aviation-related business, partially offset by the reduction in commercial and residential textile business and promotional merchandise business.
    Losses and Loss Expenses. Losses and loss expenses increased to $1,961 million in 2026 from $1,955 million in 2025. The consolidated loss ratio was 61.5% in 2026 and 63.1% in 2025. Catastrophe losses, net of reinsurance recoveries, were $62 million in 2026, compared to $99 million in 2025 driven by frequency of severe storms. Favorable prior year reserve development (net of premium offsets) was $1 million in both 2026 and 2025. The loss ratio excluding catastrophe losses and prior year reserve development decreased 0.3 points to 59.6% in 2026 from 59.9% in 2025.
    A summary of loss ratios in 2026 compared with 2025 by business segment follows:
Insurance - The loss ratio was 63.1% in 2026 and 63.8% in 2025. Catastrophe losses were $60 million in 2026 compared with $78 million in 2025. Favorable prior year reserve development was $0.7 million in 2026 and adverse prior year reserve development was $7 million in 2025.

    Expenses from Non-Insurance Businesses. Expenses from non-insurance businesses represent costs associated with businesses engaged in the distribution of promotional merchandise, world-wide textile solutions and aviation-related businesses that include (i) cost of goods sold related to aircraft and products sold and services provided, and (ii) general and administrative expenses. Expenses from non-insurance businesses were $123 million in 2026 compared to $122 million in 2025.

Income Taxes. The effective income tax rate was 21.4% and 23.2% for the three months ended June 30, 2026 and 2025, respectively. The lower effective income tax rate for the three months ended June 30, 2026, as compared to the earlier period, was primarily due to a more favorable geographical mix of earnings.
    The Company has not provided U.S. deferred income taxes on the undistributed earnings of approximately $652 million of its non-U.S. subsidiaries, since these earnings are intended to be permanently reinvested in the non-U.S. subsidiaries. In the future, if such earnings were distributed, the Company projects that the incremental tax, if any, will not be material.
In the United States, on July 4, 2025, the budget reconciliation package known as the “One Big Beautiful Bill Act” was signed into law. Changes resulting from the tax provisions thereunder did not have a material impact on the Company’s results from operations.

Investments
    As part of its investment strategy, the Company establishes a level of cash and highly liquid short-term and intermediate-term securities that, combined with expected cash flow, it believes is adequate to meet its payment obligations. In addition to fixed maturity securities, the Company invests in equity securities, merger arbitrage securities, investment funds, private equity, loans and real estate related assets. The Company's investments in investment funds and its other alternative investments have experienced, and the Company expects to continue to experience, greater fluctuations in investment income.
    The Company also attempts to maintain an appropriate relationship between the average duration of the investment portfolio and the approximate duration of its liabilities (i.e., policy claims and debt obligations). The average duration of the fixed maturity portfolio, including cash and cash equivalents, was 3.2 years at June 30, 2026 and 3.0 years at December 31, 2025. The Company’s fixed maturity investment portfolio and investment-related assets as of June 30, 2026 were as follows:

Fixed Maturity Securities. The Company’s investment policy with respect to fixed maturity securities is generally to purchase instruments with the expectation of holding them to their maturity. However, management of the available for sale portfolio is considered necessary to maintain an approximate matching of assets and liabilities as well as to adjust the portfolio as a result of changes in financial market conditions and tax considerations.
The Company’s philosophy related to holding or selling fixed maturity securities is based on its objective of maximizing total return. The key factors that management considers in its investment decisions as to whether to hold or sell fixed maturity securities are its view of the underlying fundamentals of specific securities as well as its expectations regarding interest rates, credit spreads and currency values. In a period in which management expects interest rates to rise, the Company may sell longer duration securities in order to mitigate the impact of an interest rate rise on the fair value of the portfolio. Similarly, in a period in which management expects credit spreads to widen, the Company may sell lower quality securities, and in a period in which management expects certain foreign currencies to decline in value, the Company may sell securities denominated in those foreign currencies. The sale of fixed maturity securities in order to achieve the objective of maximizing total return may result in realized gains or losses; however, there is no reason to expect these gains or losses to continue in future periods.
Equity Securities. Equity securities primarily represent investments in common and preferred stocks in companies with potential growth opportunities in different sectors, mainly in the financial institutions, energy and technology sectors.
Investment Funds. At June 30, 2026, the carrying value of investment funds was $1.4 billion, including investments in other funds of $421 million (which includes a deferred compensation trust asset of $51 million), financial services funds of $357 million, transportation funds of $274 million, infrastructure funds of $179 million, real estate funds of $157 million, and energy funds of $43 million. Investment funds are generally reported on a one-quarter lag.
Real Estate. Real estate is directly owned property held for investment. At June 30, 2026, real estate properties in operation included a long-term ground lease in Washington, D.C., an office complex in New York City and the completed portion of a mixed-use project in Washington, D.C. In addition, part of the previously mentioned mixed-use project in Washington, D.C. is under development. The Company expects to fund further development costs for the project with a combination of its own funds and external financing.
Arbitrage Trading Account. The arbitrage trading account is comprised of direct investments in arbitrage securities. Merger arbitrage is the business of investing in the securities of publicly held companies that are the targets in announced tender offers and mergers.
Loans Receivable. Loans receivable had both amortized cost and fair value of $266 million as of June 30, 2026. Loans receivable include real estate loans of $266 million secured by commercial real estate located in the U.K. Real estate loans generally earn interest at variable interest rates and have maturities through 2030.
Market Risk. The fair value of the Company’s investments is subject to risks of fluctuations in credit quality and interest rates. The Company uses various models and stress test scenarios to monitor and manage interest rate risk. The Company attempts to manage its interest rate risk by maintaining an appropriate relationship between the effective duration of the investment portfolio and the approximate duration of its liabilities (i.e., policy claims and debt obligations). The effective duration for the fixed maturity portfolio (including cash and cash equivalents) was 3.2 years at June 30, 2026 and 3.0 years at December 31, 2025.
In addition, the fair value of the Company’s international investments is subject to currency risk. The Company attempts to manage its currency risk by matching its foreign currency assets and liabilities where considered appropriate.

Liquidity and Capital Resources
    Cash Flow. Cash flow provided from operating activities increased to $1,468 million in the six months ended June 30, 2026 from $1,448 million in the six months ended June 30, 2025, primarily due to increased premium receipts, partially offset by increased loss and loss expense payments and income tax payments.
    The Company's insurance subsidiaries' principal sources of cash are premiums, investment income, service fees and proceeds from sales and maturities of portfolio investments. The principal uses of cash are payments for claims, purchase of investments, taxes, operating expenses and dividends. The Company expects its insurance subsidiaries to fund the payment of losses with cash received from premiums, investment income and fees. The Company generally targets an average duration for its investment portfolio that is within 1.5 years of the average duration of its liabilities so that portions of its investment portfolio mature throughout the claim cycle and are available for the payment of claims if necessary. In the event operating cash flow and proceeds from maturities and prepayments of fixed income securities are not sufficient to fund claim payments and other cash requirements, the remainder of the Company's cash and investments is available to pay claims and other obligations as they become due. The Company's investment portfolio is highly liquid, with approximately 83% invested in cash, cash equivalents and marketable fixed maturity securities as of June 30, 2026. If the sale of fixed maturity securities were to become necessary, a realized gain or loss equal to the difference between the cost and sales price of securities sold would be recognized.
    Debt. At June 30, 2026, the Company had senior notes, subordinated debentures and other debt outstanding with a carrying value of $2,840 million and a face amount of $2,862 million. The maturities of the outstanding debt are $7 million in 2026, $250 million in 2037, $350 million in 2044, $470 million in 2050, $400 million in 2052, $185 million in 2058, $300 million in 2059, $250 million in 2060, and $650 million in 2061.
On June 9, 2026, the Company renewed its senior unsecured revolving credit facility that provides for revolving, unsecured borrowings up to an aggregate of $300 million with a $50 million sublimit for letters of credit. The Company may increase the amount available under the facility to a maximum of $500 million subject to obtaining lender commitments for the increase and other customary conditions. Borrowings under the facility may be used for working capital and other general corporate purposes. All borrowings under the facility must be repaid by June 9, 2031, except that letters of credit outstanding on that date may remain outstanding until June 9, 2032 (or such later date approved by all lenders). Our ability to utilize the facility is conditioned on the satisfaction of representations, warranties and covenants that are customary for facilities of this type. As of June 30, 2026, there were no borrowings outstanding under the facility.
    Equity. At June 30, 2026, total common stockholders’ equity was $9.8 billion, common shares outstanding were 371,057,782 (excluding 17,378,810 shares held in a grantor trust established by the Company for delivery upon settlement of vested but mandatorily deferred RSUs), stockholders' equity per outstanding share was $26.50, and adjusted stockholders' equity per outstanding share was $25.31 (including shares held in a grantor trust).
