Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Business and Basis of Presentation | Business and Basis of Presentation Business Assured Guaranty Ltd. (AGL and, together with its subsidiaries, Assured Guaranty or the Company) is a Bermuda-based holding company that provides, through its wholly-owned operating subsidiaries, credit protection products to the United States (U.S.) and non-U.S. public finance (including infrastructure) and structured finance markets. Assured Guaranty also participates in the annuity reinsurance and asset management businesses. Financial Guaranty Insurance Through its financial guaranty (FG) insurance subsidiaries, the Company applies its credit underwriting judgment, risk management skills and capital markets experience primarily to offer FG insurance that protects holders of debt instruments and other monetary obligations from defaults in scheduled payments. If an obligor defaults on a scheduled payment, including a scheduled principal or interest payment (collectively, debt service), the Company is required under its unconditional and irrevocable financial guaranty to pay the shortfall of the scheduled amount to the holder of the obligation, but generally cannot be required by the holder to pay on an accelerated basis. The Company markets its FG insurance directly to issuers and underwriters of public finance and structured finance securities as well as to investors in such obligations. The Company guarantees obligations issued principally in the U.S. and the United Kingdom (U.K.), and also guarantees obligations issued in other countries and regions, including Western Europe and Australia. The Company also provides specialty insurance and reinsurance on transactions with risk profiles similar to those of its structured finance exposures written in financial guaranty form. The Company’s principal FG insurance subsidiaries are: •Assured Guaranty Inc. (AG), domiciled in Maryland, and its insurance subsidiaries: •Assured Guaranty UK Limited (AGUK), domiciled in the U.K.; •Assured Guaranty (Europe) SA (AGE), domiciled in France; •Assured Guaranty Re Ltd. (AG Re), domiciled in Bermuda, and its insurance subsidiary: •Assured Guaranty Re Overseas Ltd. (AGRO), domiciled in Bermuda. Annuity Reinsurance On January 21, 2026 (the Acquisition Date), the Company purchased all of the outstanding share capital in Warwick Company (UK) Limited (Warwick), which is the 100% indirect owner of Assured Life Reinsurance Ltd. (Assured Life Re), formerly known as Warwick Re Limited. Assured Life Re is a Class E long-term (life) reinsurance company incorporated and registered in Bermuda. See Note 2. Assured Life Re Acquisition. Assured Life Re specializes in annuity reinsurance. As of the date of acquisition, Assured Life Re had reinsured two blocks of business: U.K. bulk purchase annuities (pension risk transfers, PRT) denominated in pound sterling and U.S. multi-year guaranteed annuities (MYGA) denominated in U.S. dollars. PRT annuity obligations are generally long‑term, benefit‑driven cash flows that are long-dated, inflation-linked liabilities. MYGA typically provide for guaranteed crediting rates over a specified term and include contractual features such as surrender charges, market value adjustments and limited withdrawal provisions. Asset Management The Company participates in the asset management business through its approximately 30% ownership interest in Sound Point Capital Management, LP (Sound Point, LP) and certain of its investment management affiliates (together with Sound Point, LP, Sound Point). U.S. Holding Companies AGL directly or indirectly owns several holding companies. Two of these holding companies, Assured Guaranty US Holdings Inc. (AGUS) and Assured Guaranty Municipal Holdings Inc. (AGMH) (collectively, the U.S. Holding Companies), have public debt outstanding. Basis of Presentation The unaudited interim condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (GAAP). In management’s opinion, all material adjustments necessary for a fair statement of the financial condition, results of operations and cash flows of the Company, including its consolidated variable interest entities (VIEs), are reflected in the periods presented and are of a normal, recurring nature. 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 disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. These unaudited interim condensed consolidated financial statements are as of March 31, 2026 and cover the three-month period ended March 31, 2026 (first quarter 2026) and the three-month period ended March 31, 2025 (first quarter 2025). Certain financial information that is normally included in annual financial statements prepared in accordance with GAAP, but is not required for interim reporting purposes, has been condensed or omitted. The year-end condensed consolidated balance sheet data was derived from audited financial statements but does not include all disclosures required by GAAP. Certain prior year balances have been reclassified to conform to the current period’s presentation. The unaudited interim condensed consolidated financial statements include the accounts of AGL, its direct and indirect subsidiaries, and its consolidated VIEs. See Note 10. Variable Interest Entities. Intercompany accounts and transactions between and among all consolidated entities have been eliminated. All amounts are reported in U.S. dollars, unless otherwise specified. These unaudited interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements included in the Annual Report on Form 10-K for the year ended December 31, 2025 filed with the U.S. Securities and Exchange Commission. Recent Accounting Standards Not Yet Adopted In November 2024, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40). The amendments in this ASU require disclosure about specific expense categories, including employee compensation, depreciation and intangible asset amortization, in the notes to the financial statements at interim and annual reporting periods. This ASU is effective in fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027. Early adoption is permitted. Prospective application is required, and retrospective application is permitted. The Company is evaluating when and how it will adopt this ASU and the effect that the amendments in this ASU may have on its expense disclosures. In September 2025, the FASB issued ASU 2025-06, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software. This ASU updates the capitalization guidance for internal-use software development costs by removing all references to software development project stages and providing new guidance requiring an entity to start capitalizing when both of the following occur: (i) management has authorized and committed to funding a software project; and (ii) it is probable that the project will be completed and the software will be used to perform the function intended. This ASU is effective for fiscal years beginning after December 15, 2027, and interim periods within those fiscal years, with early adoption permitted. This ASU allows entities to adopt the new guidance prospectively, retrospectively or with a modified transition. The Company is evaluating when and how it will adopt this ASU and the effect it may have on its consolidated financial statements. In December 2025, the FASB issued ASU 2025-11, Interim Reporting (Topic 270): Narrow-Scope Improvements. This ASU is intended to improve the navigability of guidance in ASC 270, Interim Reporting, and clarify when it applies. The ASU also provides additional guidance on what disclosures should be provided in interim reporting periods. This ASU is effective for fiscal years beginning after December 15, 2027, including interim periods within those fiscal years, and permits prospective or full retrospective adoption. Early adoption is permitted. The Company is evaluating when and how it will adopt this ASU and the effect it may have on its consolidated financial statements and related disclosures.
