PART I
ITEM 1. BUSINESS
    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 casualty insurance business:

Insurance - Our Insurance businesses underwrite predominantly commercial insurance business, including excess and surplus lines, admitted lines and specialty personal lines throughout the United States, as well as insurance business in Asia, Australia, Canada, Continental Europe, Mexico, Scandinavia, South America and the United Kingdom.

Reinsurance & Monoline Excess - Our Reinsurance businesses provide facultative and treaty reinsurance in the United States, the Asia Pacific region, Australia, Continental Europe, South Africa and the United Kingdom, as well as operations that solely retain risk on an excess basis and certain program management business.
    Our two reporting segments are each composed of individual businesses that serve a market defined by geography, products, services or industry served. Each of our businesses is positioned close to its customer base and participates in a niche market requiring specialized knowledge. This strategy of decentralized operations allows each of our businesses to identify and respond quickly and effectively to changing market conditions and specific customer needs, while capitalizing on the benefits of centralized capital, investment and reinsurance management, and corporate actuarial, financial, enterprise risk management and compliance support.
    Our business approach is focused on meeting the needs of our customers, maintaining a high quality balance sheet, and allocating capital to our best opportunities. New businesses are started when opportunities are identified and when the right talent and expertise are found to lead a business. Of our 58 businesses, 51 have been organized and developed internally and seven have been added through acquisition.
    Net premiums written, as reported based on United States generally accepted accounting principles (“GAAP”), for each of our reporting segments for each of the past three years were as follows:
Year Ended December 31,
(In thousands)202420232022
Net premiums written:
Insurance$10,549,550 $9,560,533 $8,609,028

Percentage of net premiums written:

Reinsurance & Monoline Excess 11.9 12.7 13.9 
Total100.0 %100.0 %100.0 %
Thirty-three of our insurance company subsidiaries are rated by A.M. Best Company, Inc. ("A.M. Best") and have financial strength ratings of A+ (Superior) (the second highest rating out of 15 possible ratings). A.M. Best's ratings are based upon factors of concern to policyholders, insurance agents and brokers and are not directed toward the protection of investors. A.M. Best states: “A Best's Financial Strength Rating (FSR) is an independent opinion of an insurer's financial strength and ability to meet its ongoing insurance policy and contract obligations. An FSR is not assigned to specific insurance policies or contracts and does not address any other risk.” A.M. Best reviews its ratings on a periodic basis, and its ratings of the Company's subsidiaries are therefore subject to change.
Our twenty-three insurance company subsidiaries rated by Standard & Poor's (“S&P”) have financial strength ratings of A+ (the fifth highest rating out of twenty-seven possible ratings).
Our Moody's financial strength ratings are A1 for Berkley Insurance Company, Berkley Regional Insurance Company and Admiral Insurance Company (the fifth highest rating out of twenty-one possible ratings).
Our twenty-five insurance company subsidiaries rated by Fitch Ratings ("Fitch") have insurer financial strength ratings of AA- (the fourth highest rating out of twenty-seven possible ratings).

The businesses are identified for descriptive purposes only and are not legal entities, but for marketing purposes may sometimes be referred to individually as "a Berkley company" or collectively as "Berkley companies." Unless otherwise indicated, all references in this Form 10-K to “Berkley,” “we,” “us,” “our,” the “Company” or similar terms refer to W. R. Berkley Corporation together with its subsidiaries and businesses. W. R. Berkley Corporation is a Delaware corporation formed in 1970.

The table below represents summary underwriting ratios on a GAAP basis for our segments. Loss ratio is losses and loss expenses incurred expressed as a percentage of net premiums earned. Expense ratio is policy acquisition and insurance operating expenses expressed as a percentage of net premiums earned. Policy acquisition and insurance operating expenses do not include expenses related to insurance services or unallocated corporate expenses. Combined ratio is the sum of the loss ratio and the expense ratio. The combined ratio represents a measure of underwriting profitability, excluding investment income. A number in excess of 100 indicates an underwriting loss; a number below 100 indicates an underwriting profit:

(3)Many states require licensed insurers that provide workers' compensation insurance to participate in programs that provide workers' compensation to employers that cannot procure coverage from an insurer on a voluntary basis. Insurers can fulfill this residual market obligation by participating in pools where results are shared by the participating companies. The Company acts as a servicing carrier for workers' compensation pools in certain states. As a servicing carrier, the Company writes residual market business directly and then cedes 100% of this business to the respective pool. As a servicing carrier, the Company receives fee income for its services. The Company does not retain underwriting risk, and credit risk is limited as ceded balances are jointly shared by all the pool members.

Off-Balance Sheet Arrangements
An off-balance sheet arrangement is any transaction, agreement or other contractual arrangement involving an unconsolidated entity under which a company has (1) made guarantees, (2) a retained or contingent interest in transferred assets, (3) an obligation under derivative instruments classified as equity or (4) any obligation arising out of a material variable interest in an unconsolidated entity that provides financing, liquidity, market risk or credit risk support to the Company, or that engages in leasing, hedging or research and development arrangements with the Company. The Company has no arrangements of these types that management believes may have a material current or future effect on our financial condition, liquidity or results of operations.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
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 average number of years held for its liabilities (i.e., policy claims and debt obligations). The effective duration for the fixed maturity portfolio (including cash and cash equivalents) was 2.6 years and 2.4 years at December 31, 2024 and 2023, respectively.
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.
The following table outlines the groups of fixed maturity securities and their effective duration at December 31, 2024:
Effective
Duration
($ in thousands)(Years)Fair Value
Mortgage-backed securities4.3$3,767,851 
U.S. government and government agencies3.72,235,341

Asset-backed securities1.43,885,012 
Cash and cash equivalents0.01,404,931 
Total2.6$24,209,605 
Duration is a common measure of the price sensitivity of fixed maturity securities to changes in interest rates. The Company determines the estimated change in fair value of the fixed maturity securities, assuming parallel shifts in the yield curve for treasury securities while keeping spreads between individual securities and treasury securities static. The estimated fair value at specified levels at December 31, 2024 would be as follows:
(In thousands)Estimated Fair ValueChange in Fair Value

300 basis point decline25,928,699 1,719,094 

Arbitrage investing differs from other types of investments in that its focus is 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 believes that this makes arbitrage investments less vulnerable to changes in general stock market conditions. Potential changes in market conditions are also mitigated by the implementation of hedging strategies, including short sales.
Additionally, the arbitrage positions are generally hedged against market declines by purchasing put options, selling call options or entering into swap contracts. The Company's merger arbitrage securities are primarily exposed to the risk of completion of announced deals, which are subject to regulatory as well as transactional and other risks.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA
Report of Independent Registered Public Accounting Firm
To the Stockholders and the Board of Directors
W. R. Berkley Corporation:

Opinion on the Consolidated Financial Statements
We have audited the accompanying consolidated balance sheets of W. R. Berkley Corporation and subsidiaries (the Company) as of December 31, 2024 and 2023, the related consolidated statements of income, comprehensive income, stockholders’ equity, and cash flows for each of the years in the three‑year period ended December 31, 2024, and the related notes and financial statement schedules II to VI (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2024 and 2023, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2024, in conformity with U.S. generally accepted accounting principles.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated February 24, 2025 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.
Basis for Opinion
These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.
Critical Audit Matter
The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of a critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.
Reserves for losses and loss expenses
As discussed in Notes 1 and 13 to the consolidated financial statements, the Company estimates the reserves for losses and loss expenses (reserves) using a variety of actuarial techniques and methods. The key assumptions used to arrive at the best estimate of recorded reserves are expected loss ratios, rate of loss cost inflation, reported and paid loss emergence patterns, loss frequency and severity, and the loss reporting lag. Such amounts are adjusted for certain qualitative factors. The reserves as of December 31, 2024 were $20.4 billion.
We identified the assessment of the estimate of reserves as a critical audit matter because it involved significant measurement uncertainty, which required complex auditor judgement. Specialized actuarial skills and knowledge were required to evaluate the actuarial method or methods and assumptions used. Assumptions included loss development
62



factors; the weighting of actuarial methods when more than one was used; the impact of qualitative factors; and whether payments are fixed and reliably determinable for certain reserves subject to discounting.
The following are the primary procedures we performed to address the critical audit matter. With the assistance of actuarial professionals, when appropriate, we evaluated the design and tested the operating effectiveness of certain internal controls over the Company’s reserving process. This included controls over the Company’s process to develop the Company’s best estimate of reserves based on actuarial methodologies and assumptions employed by the Company’s actuaries. We involved actuarial professionals with specialized skills and knowledge, who assisted in:
examining the Company’s actuarial methodologies for compliance with Actuarial Standards of Practice
evaluating the Company’s ability to discount certain reserves by comparing the expected payout pattern of claims paid to actual claims paid
evaluating the Company’s actuarial point estimate by performing independent actuarial analyses for certain of the larger, more complex businesses
evaluating the Company’s actuarial point estimate by examining the Company actuaries’ process, and key assumptions for certain of the remaining businesses
developing an independent range of reserves based on actuarial methodologies and assumptions and comparing to the Company’s recorded reserves
evaluating the Company’s recorded reserves and year-over-year movements of the Company’s reserves relative to, and within, the independently developed range of reserves.

/S/
We have served as the Company’s auditor since 1972.

million and $ 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 December 31, 2024, the fair value of long option contracts outstanding was $ million (notional amount of $ million) and the fair value of short option contracts outstanding was $ million (notional amount of $ million). Other than with respect to the use of these trading account securities, the Company does not make use of derivatives.

(1)Claims occurring during the current year are net of loss reserve discounts of $ million, $ million and $ million in 2024, 2023, and 2022, 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 $ million in 2024, decreased by $ million in 2023, and increased by $ million in 2022.
The ultimate net impact of COVID-19 on the Company’s reserves remains uncertain. As of December 31, 2024, the Company had recognized losses for COVID-19-related claims activity, net of reinsurance, of approximately $ million, of which $ million relates to the Insurance segment and $ million relates to the Reinsurance & Monoline Excess segment. Such $ million of COVID-19-related losses included $ million of reported losses and $ million of IBNR.
Favorable prior year development (net of additional and return premiums) was $ million in 2024.
Insurance – Reserves for the Insurance segment developed unfavorably by $ million in 2024 (net of additional and return premiums). The adverse development was driven by the commercial auto liability and other liability occurrence lines of business, and was largely offset by favorable development for workers’ compensation, professional liability, products liability, and commercial property lines of business.
The adverse commercial auto liability development was concentrated in accident years 2021 through 2023, while the adverse other liability occurrence development was focused across accident years 2015 through 2022. The majority of the other liability occurrence development was driven by umbrella and excess liability claims, of which a significant portion related to underlying commercial auto exposures. The Company believes that commercial 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 aggressive actions by the plaintiffs’ bar such as litigation funding, negative public sentiment towards large businesses and corporations, and erosion of tort reforms, among other factors.
The favorable workers’ compensation development for the Insurance segment was mainly related to accident years 2016 through 2023, with accident years 2020 through 2023 contributing the most. For workers’ compensation, favorable reported claim frequency, below expectations, continued to be the main driver of the favorable reserve development. The
98



 million in 2024 (net of additional and return premiums). The favorable development was driven mainly by excess workers’ compensation business, partially offset by adverse development in the non-proportional reinsurance assumed liability line of business. The favorable excess workers’ compensation development was driven by continued lower claim frequency and reported losses relative to expectations, and favorable claim settlements spread across many prior accident years. The unfavorable development for non-proportional reinsurance was concentrated mainly in accident years 2015 through 2019 and was associated primarily with our U.S. and U.K. excess general liability reinsurance businesses, including coverage for cedants insuring construction projects.
Unfavorable prior year development (net of additional and return premiums) was $ million in 2023.
Insurance – Reserves for the Insurance segment developed unfavorably by $ million in 2023 (net of additional and return premiums). The unfavorable development for the segment was concentrated in the early part of the year. A key driver of the unfavorable development early in 2023 was property catastrophe losses related to 2022 events which were still being adjusted and settled during the early part of 2023. In particular, losses related to U.S. winter storms which occurred during the month of December 2022 were a significant contributor to the development, as information gathering and evaluation of many of these claims were still ongoing into the new year.
In addition to the property prior year development discussed above, during 2023 the Insurance segment also experienced adverse prior year development on casualty lines of business for the 2016 through 2019 accident years, which was offset by favorable prior year development on casualty lines of business for the 2020 through 2022 accident years. The unfavorable development on the 2016 through 2019 accident years was concentrated in the general liability and commercial auto liability lines of business. The development, which particularly impacted business attaching excess of primary policy limits, was driven by a larger than expected number of large losses reported. The Company believes social inflation is contributing to an increase in the frequency of large losses for these accident years. 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 prior year development on casualty lines for the 2020 through 2022 accident years in the Insurance segment was concentrated in the professional liability, workers’ compensation, and general liability lines of business. Due to elevated uncertainty regarding incurred loss frequency and severity as a result of ongoing social inflation and the impacts of the COVID-19 pandemic, the Company set its initial loss ratios for the 2020 through 2022 accident years prudently, and largely maintained these estimates through the end of each respective accident year. The reported loss experience to date for these lines of business for the 2020 through 2022 accident years has been significantly better than was expected, and the Company has begun to react to this favorable emergence as the accident years mature beyond the age of twelve months. It should also be noted that commercial auto liability experienced adverse prior year development for the 2020 through 2022 accident years, which partially offset the favorable development discussed above; the adverse development was driven by a larger than expected number of large losses reported.
Reinsurance & Monoline Excess – Reserves for the Reinsurance & Monoline Excess segment developed favorably by $ million in 2023 (net of additional and return premiums). The overall favorable prior year development for the segment was driven mainly by favorable development in excess workers’ compensation, substantially offset by unfavorable development in the non-proportional reinsurance assumed liability, excess general liability (including umbrella), and commercial auto liability lines of business. The favorable excess workers’ compensation development was driven by continued lower claim frequency and reported losses relative to our expectations, and to favorable claim settlements. The favorable development was spread across many prior accident years. The unfavorable development for non-proportional reinsurance assumed liability and excess general liability was associated primarily with our U.S. assumed reinsurance business, and related to accounts reinsuring excess and umbrella business and construction projects. The adverse development was concentrated mainly in accident years 2017 through 2020. The unfavorable development for commercial auto liability was concentrated in the 2022 accident year and related to commercial auto program business.
Unfavorable prior year development (net of additional and return premiums) was $ million in 2022.
99



 million in 2022 (net of additional and return premiums). The unfavorable development in the segment primarily related to COVID-19 losses at two businesses. These businesses wrote policies providing coverage for event cancellation and film production delay which were heavily impacted by losses directly caused by the COVID-19 pandemic. Most of this COVID-19 related unfavorable development emerged during the third quarter as a result of settlements of claims at values higher than our expectations. However, the Company believes that
as a result of these settlements the remaining level of uncertainty around the ultimate value of its known COVID-19 claims has been significantly reduced.
The unfavorable development mentioned above also includes favorable prior year development for the Insurance segment primarily attributable to the 2020 and 2021 accident years and unfavorable development on the 2015 through 2019 accident years. The favorable development on the 2020 and 2021 accident years was concentrated in certain casualty lines of business including general liability, professional liability, and workers’ compensation. The Company experienced lower reported claim frequency in these lines of business during 2020 and 2021 relative to historical averages, and continued to experience lower reported incurred losses relative to its expectations for these accident years as they developed during 2022. These trends began in 2020 and we believe were caused by the impacts of the COVID-19 pandemic, including for example, lockdowns, reduced driving/traffic and increased work from home. Due to the uncertainty regarding the ultimate impacts of the pandemic on accident years 2020 and 2021 incurred losses, the Company was cautious in reacting to these lower trends in setting and updating its loss ratio estimates for these years. As these accident years have continued to mature, the Company has continued to recognize some of the favorable reported experience in its ultimate loss estimates made during 2022.
The unfavorable development on the 2015 through 2019 accident years was concentrated in the general liability and professional liability, including medical professional, lines of business, as well as auto liability. The development was driven by a larger than expected number of large losses reported. The Company believes social inflation is contributing to an increase in the frequency of large losses for these accident years. 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.
Reinsurance & Monoline Excess – Reserves for the Reinsurance & Monoline Excess segment developed favorably by $ million in 2022 (net of additional and return premiums). The overall favorable development for the segment was driven mainly by favorable development in excess workers compensation, substantially offset by unfavorable development in the professional liability, non-proportional reinsurance assumed liability, and commercial auto liability lines of business. The favorable excess workers’ compensation development was spread across most prior accident years, including 2012 and prior years, and was driven by a review of the Company’s claim reporting patterns as well as a number of favorable claim settlements relative to expectations. The unfavorable professional liability and non-proportional reinsurance assumed liability development was concentrated mainly in accident years 2016 through 2018 and was associated primarily with our U.S. assumed reinsurance business and related to accounts insuring construction projects and professional liability exposures. The unfavorable development for commercial auto liability was concentrated in the 2021 accident year and related to commercial auto program business.
Environmental and Asbestos — To date, known environmental and asbestos claims have not had a material impact on the Company’s operations, because its subsidiaries generally did not insure large industrial companies that are subject to significant environmental or asbestos exposures prior to 1986 when an absolute exclusion was incorporated into standard policy language.
The Company’s net reserves for losses and loss expenses relating to asbestos and environmental claims on policies written before adoption of the absolute exclusion was $ million and $ million at December 31, 2024 and 2023, respectively. The estimation of these liabilities is subject to significantly greater than normal variation and uncertainty because it is difficult to make an actuarial estimate of these liabilities due to the absence of a generally accepted actuarial methodology for these exposures and the potential effect of significant unresolved legal matters, including coverage issues, as well as the cost of litigating the legal issues. Additionally, the determination of ultimate damages and the final allocation of such damages to financially responsible parties are highly uncertain.
Discounting — The Company discounts its liabilities for certain workers’ compensation reserves. The amount of workers’ compensation reserves that were discounted was $ million and $ million at December 31, 2024 and 2023, respectively. The aggregate net discount for those reserves, after reflecting the effects of ceded reinsurance, was $ million and $ million at December 31, 2024 and 2023, respectively. At December 31, 2024, discount rates by year ranged from % to %, with a weighted average discount rate of %.
Substantially all discounted workers’ compensation reserves (% of total discounted reserves at December 31, 2024) are 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
100



% of total discounted reserves at December 31, 2024), including reserves for quota share reinsurance and reserves related to losses regarding occupational lung disease. These reserves are discounted at statutory rates prescribed or permitted by the Department of Insurance of the State of Delaware.

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.

None.

ITEM 9A. CONTROLS AND PROCEDURES

The Company's management, including its Chief Executive Officer and Chief Financial Officer, have conducted an evaluation of the effectiveness of the Company's disclosure controls and procedures pursuant to Exchange Act Rule 13a-15(b) as of the end of the period covered by this annual report. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the Company has in place effective controls and procedures designed to ensure that information required to be disclosed by the Company in the reports it files or submits under the Exchange Act and the rules thereunder, is recorded, processed, summarized and reported within the time periods specified in the Commission's rules and forms.
During the quarter ended December 31, 2024, there were no changes in our internal controls over financial reporting that have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting.
Management's Report On Internal Control Over Financial Reporting

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

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

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of Treadway Commission. Based on our evaluation under the framework in Internal Control - Integrated Framework, our management concluded that our internal control over financial reporting was effective as of December 31, 2024.

Report of Independent Registered Public Accounting Firm
To the Stockholders and the Board of Directors
W. R. Berkley Corporation:
Opinion on Internal Control Over Financial Reporting
We have audited W. R. Berkley Corporation and subsidiaries’ (the Company) internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2024 and 2023, the related consolidated statements of income, comprehensive income, stockholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2024, and the related notes and financial statement schedules II to VI (collectively, the consolidated financial statements), and our report dated February 24, 2025 expressed an unqualified opinion on those consolidated financial statements.
Basis for Opinion
The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Report On Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
Definition and Limitations of Internal Control Over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

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