Accounting Policies [Abstract] |
Basis of Presentation | Basis of Presentation Our condensed consolidated financial statements are prepared in accordance with GAAP and include the accounts of Radian Group and its subsidiaries. All intercompany accounts and transactions, and intercompany profits and losses, have been eliminated. Certain prior period amounts have been reclassified to conform to the current period presentation. We have condensed or omitted certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with GAAP pursuant to the instructions set forth in Article 10 of Regulation S-X of the SEC. We generally refer to our holding company alone, without its consolidated subsidiaries, as “Radian Group.” We refer to Radian Group together with its consolidated subsidiaries as “Radian,” the “Company,” “we,” “us” or “our,” unless the context requires otherwise. Unless otherwise defined in this report, certain terms and acronyms used throughout this report are defined in the Glossary of Abbreviations and Acronyms included as part of this report. The financial information presented for interim periods is unaudited; however, such information reflects all adjustments that are, in the opinion of management, necessary for the fair statement of the financial position, results of operations, comprehensive income (loss) and cash flows for the interim periods presented. Such adjustments are of a normal recurring nature. The year-end condensed consolidated balance sheet data was derived from our audited financial statements but does not include all disclosures required by GAAP. To fully understand the basis of presentation, these interim financial statements and related notes contained herein should be read in conjunction with the audited financial statements and notes thereto included in our 2024 Form 10-K. The results of operations for interim periods are not necessarily indicative of results to be expected for the full year or for any other period.
Use of Estimates | Use of Estimates The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of our contingent assets and liabilities at the dates of the financial statements, as well as the reported amounts of revenues and expenses during the reporting periods. While the amounts included in our condensed consolidated financial statements include our best estimates and assumptions, actual results may vary materially.
Recent Accounting Pronouncements | Recent Accounting Pronouncements Accounting Standards Not Yet Adopted In December 2023, the FASB issued ASU 2023-09, Income Taxes—Improvements to Income Tax Disclosures, an update which enhances income tax disclosures. This guidance requires disaggregated information about an entity’s effective tax rate reconciliation as well as information on income taxes paid. This update is applicable to all public entities and is effective for fiscal years starting after December 15, 2024. Early adoption is permitted. The amendments in this update should be applied prospectively; however, retrospective application is permitted. We are currently evaluating the impact the new accounting guidance will have on our annual disclosures. In November 2024, the FASB issued ASU 2024-03, Disaggregation of Income Statement Expenses. This update requires enhanced disclosures of certain costs and expenses in the notes to the financial statements. This update is applicable to all public entities and is effective for fiscal years beginning after December 15, 2026, and interim periods beginning after December 15, 2027. Early adoption is permitted. The amendments in this update should be applied prospectively; however, retrospective application is permitted. We are currently evaluating the impact the new accounting guidance will have on our disclosures.
Segment Reporting | We have one reportable segment, Mortgage Insurance, which derives its revenue primarily from mortgage insurance. In addition to this reportable segment, in All Other we report activities for our non-reportable operating segments and other business activities that consist of: (i) income (losses) from assets held by Radian Group, our holding company; (ii) general corporate operating expenses not attributable or allocated to our reportable segment; and (iii) the operating results from certain other immaterial activities and operating segments, including our Mortgage Conduit, Title, Real Estate Services and Real Estate Technology businesses. We allocate corporate operating expenses to our Mortgage Insurance business and our immaterial operating businesses included in All Other based primarily on their respective forecasted annual percentage of total revenue, which approximates the estimated percentage of management time spent on each business. In addition, we allocate all corporate interest expense to our Mortgage Insurance segment, due to the capital-intensive nature of our Mortgage Insurance business. We do not manage assets by operating segments. See Note 1 for additional details about our Mortgage Insurance business.
