Accounting Policies [Abstract]
Significant accounting policies	2. Significant accounting policies Other than the items listed below, there were no significant updates to the Company’s significant accounting policies as described in its 2025 Form 10-K. Business combinations The Company accounts for business combinations using the acquisition method of accounting, under which the purchase price of the acquisition is allocated to the assets acquired and liabilities assumed using the fair values determined by management as of the acquisition date. Goodwill Goodwill represents the excess of acquisition cost over the fair value of the identifiable assets acquired and liabilities assumed in connection with an acquisition. The Company tests goodwill for potential impairment annually, or more frequently if events or changes in circumstances indicate that the asset is impaired. For the purpose of evaluating goodwill for impairment, the Company may first perform a qualitative assessment to determine whether it is necessary to perform a quantitative goodwill impairment test. If determined to be necessary, the quantitative test compares the fair value of a reporting unit with its carrying amount, including goodwill. If the fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is considered not impaired. If the carrying amount of the reporting unit exceeds the fair value, an impairment loss is recognized in an amount equal to that excess, limited to the total amount of goodwill allocated to that reporting unit. Recently issued accounting standards Issued and effective as of June 30, 2026 Management of Credit Losses for Accounts Receivable and Contract Assets In July 2025, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update 2025-05, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets (“ASU 2025-05”). The amendment provides guidance for estimating expected credit losses on current accounts receivable and current contract assets. ASU 2025-05 is effective for all entities for annual periods beginning after December 15, 2025, and interim reporting periods within those annual reporting periods. The Company adopted this accounting standard effective January 1, 2026 and its adoption did not have a material impact on the Company’s consolidated financial statements. Issued but not yet effective as of June 30, 2026 Expense Disaggregation Disclosures In November 2024, the FASB issued Accounting Standards Update 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses (“ASU 2024-03”). The ASU requires a public business entity to provide disaggregated disclosures of certain categories of expenses on an annual and interim basis including employee compensation, depreciation, and intangible asset amortization for each income statement line item that contains those expenses. ASU 2024-03 is effective for annual periods beginning after December 15, 2026 and interim reporting periods beginning after December 15, 2027. Management is in the process of reviewing this update to assess the impact on its consolidated financial statements and disclosures. Internal-Use Software In September 2025, the FASB issued Accounting Standards Update 2025-06, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software (“ASU 2025-06”). The amendment updates accounting guidelines around capitalizing software costs. ASU 2025-06 is effective for all entities for annual periods beginning after December 15, 2027, and interim reporting periods within those annual reporting periods. Management is in the process of reviewing this update to assess the impact on its consolidated financial statements and disclosures. The Company considers the applicability and impact of all accounting standard updates ("ASUs") issued by the FASB. ASUs issued during the three and six months ended June 30, 2026 and not listed above were assessed and either determined to be not applicable or expected to have minimal impact on the Company’s consolidated financial statements and disclosures. Reclassifications Certain comparative figures have been reclassified to conform to the current year presentation. These reclassifications had no impact on the previously reported net income (loss) or shareholders’ equity attributable to SiriusPoint shareholders.
