Accounting Policies [Abstract]
Significant Accounting Policies	2. Significant Accounting Policies 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. As further described in Note 3, certain prior period amounts have been reclassified to conform to the current period presentation to reflect the reclassification of certain businesses as held for sale and discontinued operations. 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 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. Held For Sale Classification We report a business as held for sale when management has committed to a formal plan to sell the assets, the business is available for immediate sale and is being actively marketed at a price that is reasonable in relation to its fair value, an active program to locate a buyer and other actions required to complete the plan to sell the asset have been initiated, the sale is probable and expected to be completed within one year, and it is deemed unlikely that significant changes to the plan will be made or that the plan will be withdrawn. A business classified as held for sale is reflected at the lower of its carrying amount or estimated fair value less cost to sell. If the carrying amount of the business exceeds its estimated fair value, a loss is recognized. Assets and liabilities related to a business classified as held for sale are segregated in the condensed consolidated balance sheets in the period in which the business is classified as held for sale and any prior periods presented. After a business is classified as held for sale, depreciation and amortization expense is not recognized on its assets. Discontinued Operations We report the results of operations of a business as discontinued operations if the business is classified as held for sale and represents a strategic shift that has a major effect on our financial results. In the period in which the business meets the criteria of a discontinued operation, its results are reported in income or loss from discontinued operations in the condensed consolidated statements of operations for current and prior periods, and include any required adjustment of the carrying amount to its fair value less cost to sell. In addition, tax is allocated between continuing operations and discontinued operations. The amount of tax allocated to discontinued operations is the difference between the tax originally allocated to continuing operations and the tax allocated to the reclassified amount of income from continuing operations in each period. All amounts included in these notes to the unaudited condensed consolidated financial statements relate to continuing operations unless otherwise noted. Cash flows from discontinued operations are reported separately in the condensed consolidated statements of cash flows.

2. Significant Accounting Policies

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. As further described in Note 3, certain prior period amounts have been reclassified to conform to the current period presentation to reflect the reclassification of certain businesses as held for sale and discontinued operations. 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

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.

Held For Sale Classification

We report a business as held for sale when management has committed to a formal plan to sell the assets, the business is available for immediate sale and is being actively marketed at a price that is reasonable in relation to its fair value, an active program to locate a buyer and other actions required to complete the plan to sell the asset have been initiated, the sale is probable and expected to be completed within one year, and it is deemed unlikely that significant changes to the plan will be

made or that the plan will be withdrawn. A business classified as held for sale is reflected at the lower of its carrying amount or estimated fair value less cost to sell. If the carrying amount of the business exceeds its estimated fair value, a loss is recognized. Assets and liabilities related to a business classified as held for sale are segregated in the condensed consolidated balance sheets in the period in which the business is classified as held for sale and any prior periods presented. After a business is classified as held for sale, depreciation and amortization expense is not recognized on its assets.

Discontinued Operations

We report the results of operations of a business as discontinued operations if the business is classified as held for sale and represents a strategic shift that has a major effect on our financial results. In the period in which the business meets the criteria of a discontinued operation, its results are reported in income or loss from discontinued operations in the condensed consolidated statements of operations for current and prior periods, and include any required adjustment of the carrying amount to its fair value less cost to sell. In addition, tax is allocated between continuing operations and discontinued operations. The amount of tax allocated to discontinued operations is the difference between the tax originally allocated to continuing operations and the tax allocated to the reclassified amount of income from continuing operations in each period.

All amounts included in these notes to the unaudited condensed consolidated financial statements relate to continuing operations unless otherwise noted. Cash flows from discontinued operations are reported separately in the condensed consolidated statements of cash flows. See Note 3 for additional details about our discontinued operations and our held for sale assets and liabilities.

Other Significant Accounting Policies

See Note 2 of Notes to Consolidated Financial Statements in our 2024 Form 10-K for information regarding other significant accounting policies. There have been no significant changes in our significant accounting policies from those discussed in our 2024 Form 10-K, other than those described above in “Held For Sale Classification” and “Discontinued Operations.”
