Accounting Policies [Abstract] |
Basis of Accounting, Policy | Basis of PresentationOur condensed consolidated financial statements are prepared in accordance with GAAP and include the accounts of Radian Group Inc. and its subsidiaries. All intercompany accounts and transactions, and intercompany profits and losses, have been eliminated. 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.
Reclassification, Policy | Certain prior period amounts have been reclassified to conform to current period presentation, including: (i) certain balance sheet line items now reported in other assets and (ii) certain segment reporting balances due to changes in the composition of our segments during 2020.
Use of Estimates, Policy | 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.
New Accounting Pronouncements and Changes in Accounting Principles | Recent Accounting Pronouncements Accounting Standards Adopted During 2021 In December 2019, the FASB issued ASU 2019-12, Income Taxes—Simplifying the Accounting for Income Taxes. This update simplifies the accounting for income taxes by removing certain exceptions to the general principles of ASC Topic 740 in GAAP and clarifies certain aspects to promote consistency among reporting entities. We adopted this update effective January 1, 2021. The adoption of this update did not have an impact on our financial statements and disclosures. In October 2020, the FASB issued ASU 2020-08, Codification Improvements to Subtopic 310-20, Receivables—Nonrefundable Fees and Other Costs. This update clarifies that, for each reporting period, to the extent the amortized cost basis of an individual callable debt security exceeds the amount repayable by the issuer at the next call date, the excess (i.e., the premium) should be amortized to the next call date. We adopted ASU 2020-08 on January 1, 2021 on a prospective basis. The adoption of this update did not have a material impact on our financial statements and disclosures. Accounting Standards Not Yet Adopted In August 2018, the FASB issued ASU 2018-12, Financial Services—Insurance. The new standard: (i) requires that assumptions used to measure the liability for future policy benefits be reviewed at least annually; (ii) defines and simplifies the measurement of market risk benefits; (iii) simplifies the amortization of deferred acquisition costs; and (iv) enhances the required disclosures about long-duration contracts. This update is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Early adoption is permitted. We are currently evaluating the impact on our financial statements and future disclosures as a result of this update. In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform—Facilitation of the Effects of Reference Reform on Financial Reporting. This update provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform. The amendments in this update are optional and may be elected from the date of issuance through December 31, 2022, as reference rate reform activities occur. We are currently evaluating the impact of the guidance and our options related to the practical expedients.
