Organization, Consolidation and Presentation of Financial Statements [Abstract] |
General | 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, 2024. For interim periods, the income tax provision is based upon the Company’s estimated annual effective tax rate. This rate is 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 are recorded discretely in the period in which it occurs.
