Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization, Consolidation and Presentation of Financial Statements Disclosure and Significant Accounting Policies [Text Block]	Condensed Consolidated Financial Statements—Business Overview and Significant Accounting Policies Business Overview We are a diversified mortgage and real estate services business, providing both credit-related insurance coverage and other credit risk management solutions, as well as a broad array of mortgage, real estate and title services. We have two reportable business segments—Mortgage Insurance and Services. Mortgage Insurance Our Mortgage Insurance segment provides credit-related insurance coverage, principally through private mortgage insurance on residential first-lien mortgage loans, as well as other credit risk management solutions, to mortgage lending institutions and mortgage credit investors. We provide our mortgage insurance products and services mainly through our wholly-owned subsidiary, Radian Guaranty. Private mortgage insurance plays an important role in the U.S. housing finance system because it promotes affordable home ownership and helps protect mortgage lenders, investors and other beneficiaries by mitigating default-related losses on residential mortgage loans. Generally, these loans are made to homebuyers who make down payments of less than 20% of the purchase price for their home or, in the case of refinancings, have less than 20% equity in their home. Private mortgage insurance also facilitates the sale of these low down payment loans in the secondary mortgage market, most of which are currently sold to the GSEs. Our total direct primary mortgage IIF and RIF were $237.2 billion and $60.4 billion , respectively, as of September 30, 2019 . Services Our Services segment is primarily a fee-for-service business that offers a broad array of services to market participants across the mortgage and real estate value chain. These services comprise mortgage services, real estate services and title services, including technology and turn-key solutions, that provide information and other resources used to originate, evaluate, acquire, securitize, service and monitor residential real estate and loans secured by residential real estate. These services are primarily provided to mortgage lenders, financial institutions, investors and government entities. In addition, we provide title insurance to mortgage lenders as well as directly to borrowers. Significant Accounting Policies Basis of Presentation Our 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. We refer to Radian Group Inc. together with its consolidated subsidiaries as “Radian,” the “Company,” “we,” “us” or “our,” unless the context requires otherwise. We generally refer to Radian Group Inc. alone, without its consolidated subsidiaries, as “Radian Group.” 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 and cash flows for the interim periods presented. Such adjustments are of a normal recurring nature. The year-end condensed 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 2018 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. Certain prior period amounts have been reclassified to conform to current period presentation. 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. Other Significant Accounting Policies See Note 2 of Notes to Consolidated Financial Statements in our 2018 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 2018 Form 10-K, other than described below in “— Recent Accounting Pronouncements—Accounting Standards Adopted During 2019 .” Recent Accounting Pronouncements Accounting Standards Adopted During 2019 . We adopted ASU 2016-02, Leases (“ASU 2016-02”), on January 1, 2019. Most significantly, this update requires a lessee to recognize, as of the lease commencement date, a liability to make lease payments and an asset with respect to its right to use the underlying asset for the lease term. Upon adoption for contracts in effect as of January 1, 2019, we recorded a lease liability of $73.5 million within other liabilities, and a right-of-use asset of $49.4 million within other assets, corresponding to the lease liability as adjusted for deferred rent and unamortized allowances and incentives of $24.1 million . We elected the optional transition method and the practical expedients for transitioning existing leases to the new standard as of the effective date. As a result of applying the practical expedients: (i) we did not reassess expired or existing contracts to determine if they contain additional leases; (ii) we did not reassess the lease classification for expired and existing leases; and (iii) we did not reassess initial direct costs for existing leases. Prior period amounts continue to be reported in accordance with our historic accounting under previous lease guidance. With respect to leases entered into subsequent to the adoption of this ASU, we determine if an arrangement includes a lease at inception. If it does, we recognize a right-of-use asset and lease liability in other assets and other liabilities, respectively, in our condensed consolidated balance sheet. Right-of-use assets represent our right to use an underlying asset for the lease term and are recognized net of any payments made or received from the lessor. Lease liabilities represent our obligation to make lease payments arising from the lease and are based on the present value of lease payments over the lease term. In determining the net present value of lease payments, we use our incremental borrowing rate based on the information available at the lease commencement date or as of our date of adoption, January 1, 2019. Lease expense is recognized on a straight-line basis over the expected lease term. For lease agreements entered into after the adoption of this ASU that include lease and non-lease components, such components are generally not accounted for separately. We have elected the short-term exemption for contracts with lease terms of 12 months or less. Our lease agreements primarily relate to operating leases for office space we use in our operations. Certain of our leases include renewal options and/or termination options that we did not consider in the determination of the right-of-use asset or the lease liability as we did not believe it was reasonably certain that we would exercise such options. Our lease agreements do not contain any variable lease payments, material residual value guarantees or material restrictive covenants. We do not have material sublease agreements. As of September 30, 2019 , there were no leases that had not yet commenced but that created significant rights and obligations for us. See Note 12 for more information about our lease agreements. We adopted ASU 2017-08, Receivables-Nonrefundable Fees and Other Costs, on January 1, 2019. The new standard requires certain premiums on purchased callable debt securities to be amortized to the earliest call date. The amortization period for callable debt securities purchased at a discount will not be impacted. The adoption of this update did not have a material effect on our financial statements and disclosures. Accounting Standards Not Yet Adopted. In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses, and issued subsequent amendments to the initial guidance. This ASU and the associated subsequent amendments require that financial assets measured at their amortized cost basis be presented at the net amount expected to be collected. Credit losses relating to our available for sale debt securities are to be recorded through an allowance for credit losses, rather than a write-down of the asset, with the amount of the allowance limited to the amount by which fair value is less than amortized cost. This allowance method will allow reversals of credit losses if the estimate of credit losses declines. This ASU will also affect certain of our accounts and notes receivable, including premiums receivable, and certain of our other assets, including reinsurance recoverables. However, this ASU is not applicable to the accounting for insurance losses and loss adjustment expenses. Due to the nature of our assets affected by this update, we do not expect it to have a material effect on our financial statements and disclosures. This update is effective for public companies for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted for the fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. 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, 2020, including interim periods within those fiscal years. Early adoption is permitted. We are currently evaluating the potential impact of the adoption of this update but do not expect it to have a material effect on our financial statements and disclosures. In August 2018, the FASB issued ASU 2018-15, Intangibles-Goodwill and Other-Internal-Use Software. This ASU requires the capitalization of implementation costs for activities performed in a cloud computing arrangement that is a service contract. The new standard aligns the accounting for implementation costs of hosting arrangements that are service contracts with the accounting for capitalizing internal-use software. This update is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. We are currently evaluating the potential impact of the adoption of this update but do not expect it to have a material effect on our financial statements and disclosures. In April 2019, the FASB issued ASU 2019-04, Codification Improvements related to Financial Instruments-Credit Losses, Derivatives and Hedging, and Financial Instruments. This update to the accounting standards regarding financial instruments and derivatives and hedging clarifies the accounting treatment for the measurement of credit losses and provides further clarification on previously issued updates. This update is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. We are currently evaluating the potential impact of the adoption of this update but do not expect it to have a material effect on our financial statements and disclosures.

Net Income Per Share	Net Income Per Share Basic net income per share is computed by dividing net income by the weighted-average number of common shares outstanding, while diluted net income per share is computed by dividing net income attributable to common stockholders by the sum of the weighted-average number of common shares outstanding and the weighted-average number of dilutive potential common shares. Dilutive potential common shares relate to our share-based compensation arrangements. The calculation of basic and diluted net income per share was as follows: Three Months Ended Nine Months Ended (In thousands, except per-share amounts) 2019 2018 2019 2018 Net income—basic and diluted $ 173,438 $ 142,797 $ 511,125 $ 466,232 Average common shares outstanding—basic 203,107 213,309 208,561 214,499 Dilutive effect of share-based compensation arrangements (1) 5,584 4,593 5,402 4,284 Adjusted average common shares outstanding—diluted 208,691 217,902 213,963 218,783 Net income per share: Basic $ 0.85 $ 0.67 $ 2.45 $ 2.17 Diluted $ 0.83 $ 0.66 $ 2.39 $ 2.13 ______________________ (1) The following number of shares of our common stock equivalents issued under our share-based compensation arrangements were not included in the calculation of diluted net income per share because they were anti-dilutive: Three Months Ended Nine Months Ended (In thousands) 2019 2018 2019 2018 Shares of common stock equivalents — 338 160 338

Segment Reporting [Abstract]
Segment Reporting	Segment Reporting We have two strategic business units that we manage separately—Mortgage Insurance and Services. Adjusted pretax operating income (loss) for each segment represents segment results on a standalone basis; therefore, inter-segment eliminations and reclassifications required for consolidated GAAP presentation have not been reflected. Inter-segment activities are recorded at market rates for segment reporting and eliminated in consolidation. We allocate to our Mortgage Insurance segment: (i) corporate expenses based on the segment’s forecasted annual percentage of total revenue, which approximates the estimated percentage of time spent on the segment; (ii) except as described below for periods prior to January 1, 2019, all interest expense; and (iii) all net investment income from corporate cash and investments. Prior to January 1, 2019, interest expense related to the Clayton Intercompany Note was allocated to our Services segment. Effective January 1, 2019, Radian Group recapitalized the Services segment with a capital contribution that enabled the Services segment to repay the Clayton Intercompany Note and its accumulated allocated interest expense associated with the note, and effective as of the same date, all interest expense is allocated to our Mortgage Insurance segment. We allocate to our Services segment: (i) corporate expenses based on the segment’s forecasted annual percentage of total revenue, which approximates the estimated percentage of time spent on the segment and (ii) until January 1, 2019, the allocated interest expense related to the Clayton Intercompany Note as discussed above. With the exception of goodwill and other acquired intangible assets that relate to our Services segment, which are reviewed as part of our annual goodwill impairment assessment, we do not manage assets by segment. Adjusted Pretax Operating Income (Loss) Our senior management, including our Chief Executive Officer (Radian’s chief operating decision maker), uses adjusted pretax operating income (loss) as our primary measure to evaluate the fundamental financial performance of each of Radian’s business segments and to allocate resources to the segments. Adjusted pretax operating income (loss) is defined as pretax income (loss) excluding the effects of: (i) net gains (losses) on investments and other financial instruments; (ii) loss on extinguishment of debt; (iii) amortization and impairment of goodwill and other acquired intangible assets; and (iv) impairment of other long-lived assets and other non-operating items, such as losses from the sale of lines of business and acquisition-related expenses. See Note 4 of Notes to Consolidated Financial Statements in our 2018 Form 10-K for detailed information regarding items excluded from adjusted pretax operating income (loss), including the reasons for their treatment. Although adjusted pretax operating income (loss) excludes certain items that have occurred in the past and are expected to occur in the future, the excluded items represent those that are: (i) not viewed as part of the operating performance of our primary activities or (ii) not expected to result in an economic impact equal to the amount reflected in pretax income (loss). The reconciliation of adjusted pretax operating income (loss) for our reportable segments to consolidated pretax income is as follows: Three Months Ended Nine Months Ended (In thousands) 2019 2018 2019 2018 Adjusted pretax operating income (loss): Mortgage Insurance $ 214,256 $ 204,620 $ 641,791 (1) $ 573,771 Services (1,513 ) (7,921 ) (11,139 ) (21,960 ) Total adjusted pretax operating income 212,743 196,699 630,652 551,811 Net gains (losses) on investments and other financial instruments 13,009 (4,480 ) 47,462 (30,771 ) Loss on extinguishment of debt (5,940 ) — (22,738 ) — Amortization and impairment of other acquired intangible assets (2,139 ) (3,472 ) (6,465 ) (8,968 ) Impairment of other long-lived assets and other non-operating items — (4,059 ) (5,557 ) (4,371 ) Consolidated pretax income $ 217,673 $ 184,688 $ 643,354 $ 507,701 ______________________ (1) Includes a cumulative adjustment to unearned premiums recorded in the second quarter of 2019 related to an update to the amortization rates used to recognize revenue for Single Premium Policies, as further described below. On a consolidated basis, “adjusted pretax operating income” is a measure not determined in accordance with GAAP. Total adjusted pretax operating income is not a measure of total profitability, and therefore should not be considered in isolation or viewed as a substitute for GAAP pretax income. Our definition of adjusted pretax operating income may not be comparable to similarly-named measures reported by other companies. Our results for the nine months ended September 30, 2019 include a $32.9 million increase in net premiums earned and a $0.12 increase in net income per share, due to a reduction in our unearned premiums resulting from a cumulative adjustment in the second quarter of 2019 related to an update to the amortization rates used to recognize revenue for Single Premium Policies. The update to our earned premium recognition factors also resulted in a $6.2 million reduction in other operating expenses and a $0.02 increase in net income per share due to the acceleration of earned ceding commissions related to policies covered under our Single Premium QSR Program. This cumulative adjustment reflects a change in our estimate of the period over which we recognize premiums during the life of our mortgage insurance policies. We periodically review our premium recognition models, with adjustments to the estimate, if any, reflected in current period income. See Note 2 of Notes to Consolidated Financial Statements in our 2018 Form 10-K for additional information regarding our accounting policies for insurance premiums revenue recognition. We updated the amortization rates due to the continuing increase in the significance of borrower-paid Single Premium Policies in our portfolio following our rate reductions on borrower-paid Single Premium Policies in 2018. Under the Homeowners Protection Act of 1998 (“HPA”), borrower-paid policies must be canceled automatically on the date the LTV is scheduled to reach 78% of the original value (or, if the loan is not current on that date, on the date that the loan becomes current). As a result, given the shift in our mix of Single Premium Policies toward more borrower-paid Single Premium Policies than lender-paid, the average anticipated term of our Single Premium IIF is declining compared to historical levels. We updated our analysis to reflect not only this anticipated effect of HPA cancellations on borrower-paid policies, but also changes in observed and projected loss patterns for both borrower-paid and lender-paid policies. Revenue The reconciliation of our reportable segment revenues to consolidated revenues is as follows: Three Months Ended Nine Months Ended (In thousands) 2019 2018 2019 2018 Reportable segment revenues: Mortgage Insurance $ 321,056 $ 295,031 $ 968,215 (1) $ 859,380 Services 47,378 40,901 126,406 115,577 Total reportable segment revenues 368,434 335,932 1,094,621 974,957 Add: Net gains (losses) on investments and other financial instruments 13,009 (4,480 ) 47,462 (30,771 ) Less: Inter-segment revenues (2) 1,105 766 3,152 2,653 Total revenues $ 380,338 $ 330,686 $ 1,138,931 $ 941,533 ______________________ (1) Includes a cumulative adjustment to unearned premiums recorded in the second quarter of 2019 related to an update to the amortization rates used to recognize revenue for Single Premium Policies, as further described above. (2) Inter-segment revenues included in the Services segment. The accounting standard on revenue from contracts with customers is primarily applicable to our services revenue and is not applicable to our investments and insurance products, which represent the majority of our revenue. See Notes 1 and 2 of Notes to Consolidated Financial Statements in our 2018 Form 10-K for additional information regarding our accounting policies and the services we offer. The table below represents the disaggregation of services revenues from external customers, by type: Three Months Ended Nine Months Ended (In thousands) 2019 2018 2019 2018 Services revenue Mortgage Services $ 19,218 $ 18,839 $ 51,531 $ 55,552 Real Estate Services 17,865 15,984 50,640 44,948 Title Services 5,426 1,743 12,394 6,058 Total services revenue $ 42,509 $ 36,566 $ 114,565 $ 106,558 Our services revenues are recognized over time and measured each period based on the progress to date as services are performed and made available to customers. Our contracts with customers, including payment terms, are generally short-term in nature; therefore, any impact related to timing is immaterial. Revenue expected to be recognized in any future period related to remaining performance obligations, such as contracts where revenue is recognized as invoiced and contracts with variable consideration related to undelivered performance obligations, is not material. Revenue recognized related to services made available to customers and billed is reflected in accounts and notes receivable. Revenue recognized related to services performed and not yet billed is recorded in unbilled receivables and reflected in other assets. Deferred revenue represents advance payments received from customers in advance of revenue recognition. We have no material bad-debt expense. The following represents balances related to services revenue contracts as of the dates indicated: (In thousands) September 30, December 31, Accounts Receivable $ 18,956 $ 15,461 Unbilled Receivables 25,110 19,917 Deferred Revenues 3,036 3,204

For all investment categories, the unrealized losses of 12 months or greater duration as of September 30, 2019 were generally caused by interest rate or credit spread movements since the purchase date, and as such, we expect to recover the amortized cost basis of these securities. As of September 30, 2019 , we did not have the intent to sell any available for sale securities in an unrealized loss position, and we determined that it is more likely than not that we will not be required to sell the securities before recovery of their cost basis, which may be at maturity; therefore, we did not consider these investments to be other-than-temporarily impaired at September 30, 2019 . Other-than-temporary Impairment Activity. To the extent we determine that a security is deemed to have had an other-than-temporary impairment, an impairment loss is recognized. We recognized no other-than-temporary impairment losses in earnings during the nine months ended September 30, 2019 and $1.7 million of other-than-temporary impairment losses in earnings for the nine months ended September 30, 2018 . There were no other-than-temporary impairment losses recognized in accumulated other comprehensive income (loss) for those periods. Securities Lending Agreements We participate in a securities lending program whereby we loan certain securities in our investment portfolio to third-party borrowers for short periods of time. Although we report such securities at fair value within other assets in our condensed consolidated balance sheets, rather than within investments, the detailed information we provide in this Note 5 includes these securities. See Note 4 for additional detail on the loaned securities, and see Notes 2 and 6 of Notes to Consolidated Financial Statements in our 2018 Form 10-K for additional information about our accounting policies with respect to our securities lending agreements and the collateral requirements thereunder, respectively. All of our securities lending agreements are classified as overnight and revolving. Securities collateral on deposit with us from third-party borrowers totaling $32.3 million and $16.8 million as of September 30, 2019 and December 31, 2018 , respectively, may not be transferred or re-pledged unless the third-party borrower is in default, and is therefore not reflected in our condensed consolidated financial statements.

Reinsurance Disclosures [Abstract]
Reinsurance	Reinsurance In our mortgage insurance and title insurance businesses, we use reinsurance as part of our risk distribution strategy, including to manage our capital position and risk profile. See Note 8 of Notes to Consolidated Financial Statements in our 2018 Form 10-K for more information about our use of reinsurance in our title insurance business. The reinsurance arrangements for our mortgage insurance business include p remiums ceded under the QSR Program, the Single Premium QSR Program and the Excess-of-Loss Program. The effect of all of our reinsurance programs on our net income is as follows: Three Months Ended Nine Months Ended (In thousands) 2019 2018 2019 2018 Net premiums written—insurance: Direct $ 287,000 $ 279,137 $ 828,022 $ 820,449 Assumed (1) 2,608 1,987 7,528 4,803 Ceded (2) (15,455 ) (24,348 ) (39,900 ) (76,162 ) Net premiums written—insurance $ 274,153 $ 256,776 $ 795,650 $ 749,090 Net premiums earned—insurance: Direct $ 305,493 $ 272,505 $ 919,507 (3) $ 796,448 Assumed (1) 2,614 1,994 7,545 4,822 Ceded (2) (26,922 ) (16,068 ) (83,189 ) (3) (48,945 ) Net premiums earned—insurance $ 281,185 $ 258,431 $ 843,863 (3) $ 752,325 Ceding commissions earned $ 12,153 $ 8,373 $ 37,191 (3) $ 25,728 Ceded losses 771 1,191 4,326 3,356 ______________________ (1) Includes premiums earned from our participation in certain credit risk transfer programs. (2) Net of profit commission. (3) Includes a cumulative adjustment to unearned premiums recorded in the second quarter of 2019 related to an update to the amortization rates used to recognize revenue for Single Premium Policies. See Note 3 for further information. QSR Program In 2012, Radian Guaranty entered into the QSR Program with a third-party reinsurance provider. Radian Guaranty has ceded the maximum amount permitted under the QSR Program and is no longer ceding additional NIW under this program. RIF ceded under the QSR Program was $0.7 billion and $1.0 billion as of September 30, 2019 and 2018 , respectively. Single Premium QSR Program In the first quarter of 2016, Radian Guaranty entered into the 2016 Single Premium QSR Agreement with a panel of third-party reinsurers. As of January 1, 2018, Radian Guaranty is no longer ceding additional NIW under this arrangement. RIF ceded under the 2016 Single Premium QSR Agreement was $5.7 billion and $6.4 billion as of September 30, 2019 and 2018 , respectively. In October 2017, Radian Guaranty entered into the 2018 Single Premium QSR Agreement with a panel of third-party reinsurers. Under the 2018 Single Premium QSR Agreement, we expect to cede up to 65% of our Single Premium NIW beginning with the business written in January 2018, subject to certain conditions that may affect the amount ceded, including a limitation on ceded premiums written equal to $335 million for policies issued between January 1, 2018 and December 31, 2019. Notwithstanding this limitation, the parties may mutually agree to amend the agreement, including with respect to any limitations on the amounts of insurance that may be ceded. RIF ceded under the 2018 Single Premium QSR Agreement was $2.9 billion and $1.6 billion as of September 30, 2019 and 2018 , respectively. Excess-of-Loss Program Since the fourth quarter of 2018, Radian Guaranty has entered into two fully collateralized reinsurance arrangements with the Eagle Re Issuers. Total ceded premiums earned under our Excess-of-Loss Program were $7.5 million and $18.4 million for the three and nine months ended September 30, 2019 , respectively. The Eagle Re 2018-1 reinsurance agreement, entered into in November 2018, provides for up to $434.0 million of aggregate excess-of-loss reinsurance coverage for a specified percentage of mortgage insurance losses on new defaults on an existing portfolio of eligible Recurring Premium Policies issued between January 1, 2017 and December 31, 2017, with an initial RIF of $9.1 billion . In addition, Radian Guaranty entered into a separate excess-of-loss reinsurance agreement for up to $21.4 million of coverage, representing a pro rata share of the credit risk alongside the risk assumed by Eagle Re 2018-1 on those Recurring Premium Policies. Eagle Re 2018-1 financed its coverage by issuing mortgage insurance-linked notes in an aggregate amount of $434.0 million to eligible third-party capital markets investors in an unregistered private offering. Radian Guaranty and its affiliates have retained the first-loss layer of $204.9 million of aggregate losses, as well as any losses in excess of the outstanding reinsurance coverage amount. The Eagle Re 2019-1 reinsurance agreement, entered into in April 2019, provides for up to $562.0 million of aggregate excess-of-loss reinsurance coverage for a specified percentage of mortgage insurance losses on new defaults on an existing portfolio of eligible Recurring Premium Policies issued between January 1, 2018 and December 31, 2018, with an initial RIF of $10.7 billion . Eagle Re 2019-1 financed its coverage by issuing mortgage insurance-linked notes in an aggregate amount of $562.0 million to eligible third-party capital markets investors in an unregistered private offering. Radian Guaranty and its affiliates have retained the first-loss layer of $267.6 million of aggregate losses, as well as any losses in excess of the outstanding reinsurance coverage amount. The aggregate excess-of-loss reinsurance coverage for these transactions decreases over a ten -year period as the principal balances of the underlying covered mortgages decrease and as any claims are paid by the applicable Eagle Re Issuer or the mortgage insurance is canceled. The outstanding reinsurance coverage amount will begin amortizing after an initial period in which a target level of credit enhancement is obtained and will stop amortizing if certain thresholds are reached, such as if the reinsured mortgages were to experience an elevated level of delinquencies or certain credit enhancement tests were not maintained. Radian Guaranty has rights to terminate the reinsurance agreements upon the occurrence of certain events. The Eagle Re Issuers are not subsidiaries or affiliates of Radian Guaranty. Based on the accounting guidance that addresses VIEs, we have not consolidated any of the Eagle Re Issuers in our consolidated financial statements, because Radian does not have: (i) the power to direct the activities that most significantly affect the Eagle Re Issuers’ economic performances or (ii) the obligation to absorb losses or the right to receive benefits from the Eagle Re Issuers that potentially could be significant to the Eagle Re Issuers. See Note 2 of Notes to Consolidated Financial Statements in our 2018 Form 10-K for more information on our accounting treatment of VIEs. The Eagle Re Issuers represent our only VIEs as of September 30, 2019 . The following table presents the total assets of the Eagle Re Issuers as well as Radian Guaranty’s maximum exposure to loss associated with each Eagle Re Issuer, as of the dates indicated. At September 30, 2019 Maximum Exposure to Loss (In thousands) Total VIE Assets (1) On - Balance Sheet Off - Balance Sheet (2) Total Eagle Re 2018-1 $ 408,586 $ 1,493 (3) $ 408,586 $ 410,079 Eagle Re 2019-1 562,036 2,202 (3) 562,036 564,238 Total $ 970,622 $ 3,695 $ 970,622 $ 974,317 At December 31, 2018 Maximum Exposure to Loss (In thousands) Total VIE Assets (1) On - Balance Sheet Off - Balance Sheet (2) Total Eagle Re 2018-1 $ 434,034 $ 1,114 (3) $ 434,034 $ 435,148 Total $ 434,034 $ 1,114 $ 434,034 $ 435,148 ______________________ (1) Assets held by the Eagle Re Issuers are required to be invested in U.S. government money market funds, cash or U.S. Treasury securities. Liabilities of the Eagle Re Issuers consist of their mortgage insurance-linked notes, described above. (2) Represents Radian Guaranty’s maximum exposure to loss in the event the VIE is unable to meet its obligations to us and our insurance subsidiaries would be liable to make claims payments to our policyholders. In the event that all of the assets in the reinsurance trust (consisting of U.S. government money market funds, cash or U.S. Treasury securities) were to lose their value and the VIE is unable to make its payments to us, our maximum potential loss would be the amount of mortgage insurance claim payments for losses on the insured policies, net of the aggregate reinsurance payments already received, up to the full aggregate excess-of-loss reinsurance coverage amount. In the same scenario, the related embedded derivative would no longer have value. (3) Represents the fair value of the related embedded derivative, included in other assets in our condensed consolidated balance sheets. Collateral Although we use reinsurance as one of our risk management tools, reinsurance does not relieve us of our obligations to our policyholders. In the event the reinsurers are unable to meet their obligations to us, our insurance subsidiaries would be liable for any defaulted amounts. However, consistent with the PMIERs reinsurer counterparty collateral requirements, Radian Guaranty’s reinsurers have established a trust to help secure our potential cash recoveries. In addition, for the Single Premium QSR Program, Radian Guaranty holds amounts received from ceded premiums written to collateralize the reinsurers’ obligations, which are reported in reinsurance funds withheld on our condensed consolidated balance sheets. Any loss recoveries and profit commissions paid to Radian Guaranty related to the Single Premium QSR Program are expected to be realized from this account. See Note 8 of Notes to Consolidated Financial Statements in our 2018 Form 10-K for more information about our reinsurance transactions.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Certain entities within our consolidated group have generated deferred tax assets of approximately $68.0 million , relating primarily to state and local NOL carryforwards, which, if unutilized, will expire during various future tax periods. We are required to establish a valuation allowance against our deferred tax assets when it is more likely than not that all or some portion of our deferred tax assets will not be realized. At each balance sheet date, we assess our need for a valuation allowance and this assessment is based on all available evidence, both positive and negative. This requires management to exercise judgment and make assumptions regarding whether our deferred tax assets will be realized in future periods. We have determined that certain entities within Radian may continue to generate taxable losses on a separate company basis in the near term and may not be able to fully utilize certain of their state and local NOLs on their state and local tax returns. Therefore, with respect to deferred tax assets relating to these state and local NOLs and other state timing adjustments, we retained a valuation allowance of $67.9 million at September 30, 2019 . In July 2018, we finalized a settlement with the IRS related to adjustments we had been contesting that resulted from the examination of our 2000 through 2007 consolidated federal income tax returns. During 2018, under the terms of the settlement, Radian utilized its qualified deposits with the U.S. Treasury to settle its $31.0 million obligation to the IRS, and during the first quarter of 2019, the IRS refunded to Radian the remaining $57.2 million that was previously on deposit resulting in a reduction of our current federal income tax receivable. As of September 30, 2019 , our current federal income tax liability is $33.4 million and is included as a component of other liabilities in our condensed consolidated balance sheets. As a mortgage guaranty insurer, we are eligible for a tax deduction, subject to certain limitations, under IRC Section 832(e) for amounts required by state law or regulation to be set aside in statutory contingency reserves. The deduction is allowed only to the extent that we purchase non-interest bearing U.S. Mortgage Guaranty Tax and Loss Bonds issued by the U.S. Treasury in an amount equal to the tax benefit derived from deducting any portion of our statutory contingency reserves. As of September 30, 2019 , we held $89.2 million of these bonds, which are included as prepaid income taxes within other assets in our condensed consolidated balance sheets. The corresponding deduction of our statutory contingency reserves resulted in the recognition of a net deferred tax liability, which is included in other liabilities in our condensed consolidated balance sheets. For additional information on our income taxes, including our accounting policies, see Notes 2 and 10 of Notes to Consolidated Financial Statements in our 2018 Form 10-K.

For all periods presented, total incurred losses and paid claims for Radian Title Insurance were not material. See Note 8 of Notes to Consolidated Financial Statements in our 2018 Form 10-K for additional information about our use of reinsurance in our title insurance business. The following table presents information relating to our mortgage insurance reserve for losses, including our IBNR reserve and LAE, but excluding our second-lien mortgage loan premium deficiency reserve, for the periods indicated: Nine Months Ended (In thousands) 2019 2018 Balance at beginning of period $ 397,891 $ 507,588 Less: Reinsurance recoverables (1) 11,009 8,350 Balance at beginning of period, net of reinsurance recoverables 386,882 499,238 Add: Losses and LAE incurred in respect of default notices reported and unreported in: Current year (2) 107,866 100,047 Prior years (10,579 ) (24,075 ) Total incurred 97,287 75,972 Deduct: Paid claims and LAE related to: Current year (2) 1,784 2,316 Prior years 101,927 173,911 Total paid 103,711 176,227 Balance at end of period, net of reinsurance recoverables 380,458 398,983 Add: Reinsurance recoverables (1) 13,629 9,997 Balance at end of period $ 394,087 $ 408,980 ______________________ (1) Related to ceded losses recoverable, if any, on reinsurance transactions. See Note 7 for additional information. (2) Related to underlying defaulted loans with a most recent default notice dated in the year indicated. For example, if a loan had defaulted in a prior year, but then subsequently cured and later re-defaulted in the current year, that default would be considered a current year default. Reserve Activity 2019 Activity Reserves established for new default notices were the primary driver of our total incurred losses for the nine months ended September 30, 2019 , and they were primarily impacted by the number of new primary default notices received in the period and our related gross Default to Claim Rate assumption applied to those new defaults, which was 7.5% as of September 30, 2019 . Our provision for losses during the first nine months of 2019 was positively impacted by favorable reserve development on prior year defaults. This favorable development was primarily driven by a reduction during the period in certain Default to Claim Rate assumptions for these prior year defaults compared to the assumptions used at December 31, 2018, partially offset by an increase in our IBNR reserve estimate in the nine months ended September 30, 2019 related to previously disclosed legal proceedings. See Note 12 for additional information. Total claims paid decreased for the nine months ended September 30, 2019 , compared to the same period in 2018 . The decrease in claims paid is consistent with the ongoing decline in the outstanding default inventory. 2018 Activity Our mortgage insurance loss reserves at September 30, 2018 declined as compared to December 31, 2017 , primarily as a result of the amount of paid claims outpacing losses incurred related to new default notices reported in the current year. Reserves established for new default notices were the primary driver of our incurred loss for the nine months ended September 30, 2018 , and they were primarily impacted by the number of new primary default notices received in the period and our related gross Default to Claim Rate assumption applied to those new defaults, which was 8.5% as of September 30, 2018 . The provision for losses during the first nine months of 2018 was positively impacted by favorable reserve development on prior year defaults, which was primarily driven by a reduction during the period in certain Default to Claim Rate assumptions for these prior year defaults compared to the assumptions used at December 31, 2017. The reductions in Default to Claim Rate assumptions resulted from observed trends, primarily higher Cures than were previously estimated. Mortgage Insurance Reserve Assumptions Default to Claim Rate As of September 30, 2019 our gross Default to Claim Rate assumptions on our primary portfolio ranged from 7.5% for new defaults, up to 65% for defaults not in foreclosure stage, and 72%

Repurchases of Senior Notes due 2020 and 2021 During the second quarter of 2019, pursuant to cash tender offers to purchase any and all of our outstanding Senior Notes due 2020 and 2021, we purchased aggregate principal amounts of $207.2 million and $127.3 million of our Senior Notes due 2020 and 2021, respectively. We funded the purchases with $351.8 million in cash (which includes accrued and unpaid interest due on the purchased notes). These purchases resulted in a loss on extinguishment of debt of $16.8 million . In the third quarter of 2019, we redeemed the remaining $27.0 million and $70.4 million aggregate principal amount of Senior Notes due 2020 and 2021, respectively, in accordance with the terms of the related indentures. The aggregate redemption amount paid was $103.1 million , which includes accrued interest through the applicable redemption dates. These purchases resulted in a loss on extinguishment of debt of $5.9 million . Following these purchases and redemptions, there were no remaining principal amounts outstanding on the Senior Notes due 2020 and 2021 at September 30, 2019 . Senior Notes due 2027 In June 2019, we issued $450 million aggregate principal amount of Senior Notes due 2027 and received net proceeds of $442.2 million . These notes mature on March 15, 2027 and bear interest at a rate of 4.875% per annum, payable semi-annually on March 15 and September 15 of each year, with interest payments commencing on March 15, 2020. We have the option to redeem these notes, in whole or in part, at any time, or from time to time, prior to September 15, 2026 (the date that is six months prior to the maturity date of the notes) (the “Par Call Date”), at a redemption price equal to the greater of (i) 100% of the aggregate principal amount of the notes to be redeemed and (ii) the make-whole amount, which is the sum of the present values of the remaining scheduled payments of principal and interest in respect of the notes to be redeemed from the redemption date to the Par Call Date discounted to the redemption date at the applicable treasury rate plus 50 basis points, plus, in each case, accrued and unpaid interest thereon to, but excluding, the redemption date. At any time on or after the Par Call Date, we may, at our option, redeem the notes in whole or in part, at a redemption price equal to 100% of the aggregate principal amount of the notes to be redeemed, plus accrued and unpaid interest thereon to, but excluding, the redemption date. The indenture governing the Senior Notes due 2027 contains covenants customary for securities of this nature, including covenants related to the payments of the notes, reports to be provided, compliance certificates to be issued and the ability to modify the covenants. Additionally, the indenture includes covenants restricting us from encumbering the capital stock of a designated subsidiary (as defined in the indenture for the notes) or disposing of any capital stock of any designated subsidiary unless either all of the stock is disposed of or we retain more than 80% of the stock. FHLB Advances Principal on FHLB advances is due at maturity. For obligations with original maturities greater than or equal to 90 days , we may prepay the debt at any time, subject to a prepayment fee calculation.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies We are routinely involved in a number of legal actions and proceedings, including litigation and other disputes arising in the ordinary course of our business. The legal and regulatory matters discussed below and in our 2018 Form 10-K could result in adverse judgments, settlements, fines, injunctions, restitutions or other relief that could require significant expenditures or have other effects on our business. Management believes, based on current knowledge and after consultation with counsel, that the outcome of such actions will not have a material adverse effect on our consolidated financial condition. The outcome of litigation and other legal and regulatory matters and proceedings is inherently uncertain, and it is possible that one or more of the matters currently pending or threatened could have an adverse effect on our liquidity, financial condition or results of operations for any particular period. On December 22, 2016, Ocwen Loan Servicing, LLC and Homeward Residential, Inc. (collectively, “Ocwen”) filed a complaint in the U.S. District Court for the Eastern District of Pennsylvania against Radian Guaranty alleging breach of contract and bad faith claims and seeking monetary damages and declaratory relief. Ocwen has also initiated similar legal proceedings against several other mortgage insurers. On December 17, 2016, Ocwen separately filed a parallel arbitration petition against Radian Guaranty before the American Arbitration Association (“AAA”) asserting substantially the same allegations (the “Arbitration”). Ocwen’s filings together listed 9,420 mortgage insurance certificates issued under multiple insurance policies, including Pool Insurance policies, as subject to the dispute. On June 5, 2017, Ocwen filed an amended complaint and an amended petition (collectively, the “Amended Filings”) with both the court and the AAA, respectively, together listing 8,870 certificates as subject to the dispute. On April 11, 2018, the parties entered into a confidential agreement with respect to all certificates subject to the dispute. The confidential agreement resolved certain categories of claims involved in the dispute and, on April 12, 2018, the parties filed a stipulation of voluntary dismissal of the federal court proceeding and the trial judge issued an Order dismissing all claims and counterclaims subject to the parties’ agreement. Radian Guaranty was not required to make any payment in connection with this confidential agreement. Pursuant to the confidential agreement, the parties: (1) dismissed the federal court proceeding; (2) narrowed the scope of the dispute to Ocwen’s breach of contract claims seeking payment of insurance benefits on approximately 2,500 certificates that Ocwen was previously pursuing through the Amended Filings; and (3) agreed to resolve the remaining dispute through the Arbitration. The Arbitration is proceeding, and Radian continues to defend against Ocwen’s claims vigorously. On August 31, 2018, Nationstar Mortgage LLC d/b/a Mr. Cooper (“Nationstar”) filed a complaint in the U.S. District Court for the Eastern District of Pennsylvania against Radian Guaranty (the “Complaint”) alleging breach of contract, bad faith, equitable indemnification, unjust enrichment, and conversion claims and seeking monetary damages and declaratory relief. Exhibit 1 to the Complaint lists 3,014 mortgage insurance certificates issued under multiple insurance policies as subject to disputes involving insurance coverage decisions (the “Coverage Disputed Loans”). Exhibit 2 to the Complaint further lists 2,231 mortgage insurance certificates issued under multiple insurance policies as subject to disputes involving premium refund requests. In December 2018, Radian Guaranty filed a motion to dismiss the Complaint. In March 2019, the trial judge issued an order granting in part, and denying in part, our motion to dismiss, and dismissed Nationstar’s unjust enrichment and conversion claims. In May 2019, Radian Guaranty filed an answer, with affirmative defenses and counterclaims, in response to the Complaint. On September 23, 2019, the trial judge entered as an order a joint stipulation submitted by Nationstar and Radian Guaranty that narrowed the scope of the dispute involving Coverage Disputed Loans to claims relating to 1,704 mortgage insurance certificates. Radian Guaranty believes that Nationstar’s allegations and claims in the legal proceedings described above are without merit and legally deficient, and continues to defend against these claims vigorously. In the three and nine months ended September 30, 2019, the Company increased its IBNR reserve estimate by $11.8 million and $31.2 million, respectively, related to our best estimate of our probable loss in connection with the above legal proceedings. While Radian believes it has substantial defenses in these matters and intends to continue to defend against these claims vigorously, it is not feasible to predict the ultimate outcome of these disputes, and the Company could in the future be required to pay amounts as a result of settlements or decisions in these matters, potentially in excess of accruals. We also are periodically subject to reviews and audits, as well as inquiries, information-gathering requests and investigations. In connection with these matters, from time to time we receive requests and subpoenas seeking information and documents related to aspects of our business. Our Master Policies establish the timeline within which any suit or action arising from any right of an insured under the policy generally must be commenced. In general, any suit or action arising from any right of an insured under the policy must be commenced within two years after such right first arose for primary insurance and within three years for certain other policies, including certain Pool Insurance policies. Although we believe that our Loss Mitigation Activities are justified under our policies, from time to time we face challenges from certain lender and servicer customers regarding our Loss Mitigation Activities. These challenges could result in additional arbitration or judicial proceedings and we may need to reassume the risk on, and increase loss reserves for, the associated policies or pay additional claims. Lease Liability Our lease liability represents the present value of future lease payments over the lease term. Our leases do not provide a readily determinable implicit rate. Therefore, we must estimate our incremental borrowing rate, on a collateralized basis, to discount the lease payments based on information available at lease commencement. Our leases expire periodically through August 2032, and contain provisions for scheduled periodic rent increases. We estimate the incremental borrowing rate based on the yields of Radian Group corporate bonds, as adjusted to reflect a collateralized borrowing rate, resulting in discount rates ranging from 4.22% to 7.08% . While the majority of our lease population expires within one year of one of the Radian Group corporate bonds, our more significant leases do not. For those leases, we adjust the corporate bond rate for both U.S. Treasury rate yields and a corporate spread adjustment determined from recent market data. The following tables provide additional information related to our leases, including: (i) the components of our total lease cost; (ii) the cash flows arising from our lease transactions; (iii) supplemental balance sheet information; (iv) the weighted-average remaining lease term; (v) the weighted-average discount rate used for our leases; and (vi) the remaining maturities of our lease liabilities, as of and for the periods indicated: ($ in thousands) Three Months Ended September 30, 2019 Nine Months Ended September 30, 2019 Operating lease cost $ 2,340 $ 7,006 Short-term lease cost 36 111 Total lease cost $ 2,376 $ 7,117 Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows from operating leases $ (2,657 ) $ (7,933 ) ($ in thousands) September 30, 2019 Operating leases: Operating lease right-of-use assets (1) $ 42,613 Operating lease liabilities (2) 65,816 Weighted-average remaining lease term - operating leases (in years) 10.0 years Weighted-average discount rate - operating leases 6.77 % Remaining maturities of lease liabilities for the remainder of 2019 and thereafter is as follows: 2019 $ 2,681 2020 10,408 2021 9,945 2022 10,140 2023 10,279 2024 and thereafter 56,421 Total lease payments 99,874 Less: Imputed interest (34,058 ) Present value of lease liabilities (2) $ 65,816 ______________________ (1) Classified in other assets in our condensed consolidated balance sheets. See Note 8 . (2) Classified in other liabilities in our condensed consolidated balance sheets. Pursuant to the previous lease accounting standard, rent expense for the three and nine months ended September 30, 2018 was $2.5 million and $6.8 million , respectively. Our commitment for non-cancelable leases in future years as of December 31, 2018 was as follows (in thousands): 2019 $ 11,310 2020 10,847 2021 10,165 2022 10,100 2023 10,251 2024 and thereafter 56,317 Total $ 108,990 At December 31, 2018 , there were no future minimum receipts expected from sublease rental payments.

Equity [Abstract]
Stockholders' Equity Note Disclosure [Text Block]	Capital Stock Share Repurchase Program On August 16, 2018, Radian Group’s board of directors approved a share repurchase program that authorized the Company to repurchase up to $100 million of its common stock in the open market or in privately negotiated transactions, based on market and business conditions, stock price and other factors. On March 20, 2019, Radian Group’s board of directors approved a $150 million increase in authorization for this program, bringing the total authorization to repurchase shares up to $250 million , excluding commissions. Radian operated this program pursuant to a trading plan under Rule 10b5-1 of the Exchange Act, which permitted the Company to purchase shares, at pre-determined price targets, when it may have otherwise been precluded from doing so. During the three and nine months ended September 30, 2019 , the Company purchased 2,241,568 and 11,258,574 shares at an average price of $23.43 and $22.22 per share, respectively, including commissions. As of September 30, 2019 , no further purchase authority remains under this program. Over the course of this program, the Company repurchased a total of 11,258,574 shares, or 5.3% of the shares outstanding at the beginning of the program. On August 14, 2019, Radian Group’s board of directors approved a new share repurchase program that authorizes the Company to spend up to $200 million , excluding commissions, to repurchase Radian Group common stock in the open market or in privately negotiated transactions, based on market and business conditions, stock price and other factors. Radian operates this program pursuant to a trading plan under Rule 10b5-1 of the Exchange Act, which permits the Company to purchase shares, at pre-determined price targets, when it may otherwise be precluded from doing so. During the three months ended September 30, 2019 , the Company purchased 1,104,786 shares at an average price of $22.64 per share, including commissions. As of September 30, 2019 , purchase authority of up to $175.0 million remained available under this program, which expires on August 31, 2020. Subsequent to September 30, 2019 , the Company purchased 1,090,875 shares of its common stock under its share repurchase program at an average price of $22.93 per share, including commissions. As of November 8, 2019 , purchase authority of up to $150.0 million remained available under this program. Other Purchases We may purchase shares on the open market to settle stock options exercised by employees and purchases under our Employee Stock Purchase Plan. In addition, upon the vesting of certain restricted stock awards under our equity compensation plans, we may withhold from such vested awards shares of our common stock to satisfy the tax liability of the award recipients. Dividends Paid During each of the first three quarters of 2019 and each quarter of 2018 , we declared quarterly cash dividends on our common stock equal to $0.0025 per share.

Note 15 - Statutory Information	9 Months Ended
	Sep. 30, 2019
SEC Schedule, 12-16, Insurance Companies, Supplementary Insurance Information [Abstract]
Statutory Information	Statutory Information State insurance regulations include various capital requirements and dividend restrictions based on our insurance subsidiaries’ statutory financial position and results of operations, as described below. As of September 30, 2019 , the amount of restricted net assets held by our consolidated insurance subsidiaries (which represents our equity investment in those insurance subsidiaries) totaled $4.0 billion of our consolidated net assets. Under state insurance regulations, our mortgage insurance subsidiaries are required to maintain minimum surplus levels. In certain RBC States, mortgage insurers licensed in those states must also satisfy a Statutory RBC Requirement that is a minimum ratio of statutory capital relative to the level of net RIF, or Risk-to-capital. Other RBC States require mortgage insurers licensed in those states to satisfy a MPP Requirement that is calculated on both risk and surplus levels. Our mortgage insurance subsidiaries were in compliance with the Statutory RBC Requirements or MPP Requirements, to the extent applicable, in each of the RBC States as of September 30, 2019 . In addition, in order to be eligible to insure loans purchased by the GSEs, mortgage insurers such as Radian Guaranty must meet the GSEs’ eligibility requirements, or PMIERs. At September 30, 2019 , Radian Guaranty is an approved mortgage insurer under the PMIERs and is in compliance with the current PMIERs financial requirements. See Note 1 of Notes to Consolidated Financial Statements in our 2018 Form 10-K for additional information regarding the PMIERs. Radian Guaranty’s Risk-to-capital calculation appears in the table below. For purposes of the Risk-to-capital requirements imposed by certain states, statutory capital is defined as the sum of statutory policyholders’ surplus plus statutory contingency reserves. September 30, December 31, ($ in millions) RIF, net (1) $ 43,484.8 $ 40,711.3 Common stock and paid-in capital $ 1,041.0 $ 1,416.0 Surplus Note 100.0 100.0 Unassigned earnings (deficit) (553.5 ) (701.9 ) Statutory policyholders’ surplus 587.5 814.1 Contingency reserve 2,475.9 2,109.9 Statutory capital $ 3,063.4 $ 2,924.0 Risk-to-capital 14.2:1 13.9:1 ______________________ (1) Excludes risk ceded through all reinsurance programs (including with affiliates) and RIF on defaulted loans. Radian Guaranty’s statutory capital increased by $139.4 million in the first nine months of 2019 , primarily due to Radian Guaranty’s statutory net income of $525.5 million during this period, partially offset by the effect of an Extraordinary Distribution paid to Radian Group, as described below. The net increase in Radian Guaranty’s Risk-to-capital in the first nine months of 2019 was primarily due to the increase in RIF, partially offset by the increase in overall statutory capital. The Risk-to-capital ratio for our combined mortgage insurance operations was 12.9 to 1 as of September 30, 2019 , compared to 12.8 to 1 as of December 31, 2018 . In April 2019, the Pennsylvania Insurance Department approved a $375 million Extraordinary Distribution from Radian Guaranty to Radian Group, which was paid on April 30, 2019 in the form of cash and marketable securities, resulting in a $375 million decrease in Radian Guaranty’s statutory policyholders’ surplus. For a description of our statutory compliance with regulations for our mortgage insurance and title services businesses, see Note 19 of Notes to Consolidated Financial Statements in our 2018 Form 10-K.

Note 1 - Condensed Consolidated Financial Statements - Business Overview and Significant Accounting Policies (Policies)	9 Months Ended
	Sep. 30, 2019
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Accounting, Policy	Our 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.
Use of Estimates, Policy	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.
Lessee, Leases, Policy	we determine if an arrangement includes a lease at inception. If it does, we recognize a right-of-use asset and lease liability in other assets and other liabilities, respectively, in our condensed consolidated balance sheet. Right-of-use assets represent our right to use an underlying asset for the lease term and are recognized net of any payments made or received from the lessor. Lease liabilities represent our obligation to make lease payments arising from the lease and are based on the present value of lease payments over the lease term. In determining the net present value of lease payments, we use our incremental borrowing rate based on the information available at the lease commencement date or as of our date of adoption, January 1, 2019. Lease expense is recognized on a straight-line basis over the expected lease term. For lease agreements entered into after the adoption of this ASU that include lease and non-lease components, such components are generally not accounted for separately. We have elected the short-term exemption for contracts with lease terms of 12 months or less.
New Accounting Pronouncements and Changes in Accounting Principles	Accounting Standards Adopted During 2019 . We adopted ASU 2016-02, Leases (“ASU 2016-02”), on January 1, 2019. Most significantly, this update requires a lessee to recognize, as of the lease commencement date, a liability to make lease payments and an asset with respect to its right to use the underlying asset for the lease term. Upon adoption for contracts in effect as of January 1, 2019, we recorded a lease liability of $73.5 million within other liabilities, and a right-of-use asset of $49.4 million within other assets, corresponding to the lease liability as adjusted for deferred rent and unamortized allowances and incentives of $24.1 million . We elected the optional transition method and the practical expedients for transitioning existing leases to the new standard as of the effective date. As a result of applying the practical expedients: (i) we did not reassess expired or existing contracts to determine if they contain additional leases; (ii) we did not reassess the lease classification for expired and existing leases; and (iii) we did not reassess initial direct costs for existing leases. Prior period amounts continue to be reported in accordance with our historic accounting under previous lease guidance. We adopted ASU 2017-08, Receivables-Nonrefundable Fees and Other Costs, on January 1, 2019. The new standard requires certain premiums on purchased callable debt securities to be amortized to the earliest call date. The amortization period for callable debt securities purchased at a discount will not be impacted. The adoption of this update did not have a material effect on our financial statements and disclosures.
New Accounting Pronouncements Not Yet Adopted, Policy	Accounting Standards Not Yet Adopted. In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses, and issued subsequent amendments to the initial guidance. This ASU and the associated subsequent amendments require that financial assets measured at their amortized cost basis be presented at the net amount expected to be collected. Credit losses relating to our available for sale debt securities are to be recorded through an allowance for credit losses, rather than a write-down of the asset, with the amount of the allowance limited to the amount by which fair value is less than amortized cost. This allowance method will allow reversals of credit losses if the estimate of credit losses declines. This ASU will also affect certain of our accounts and notes receivable, including premiums receivable, and certain of our other assets, including reinsurance recoverables. However, this ASU is not applicable to the accounting for insurance losses and loss adjustment expenses. Due to the nature of our assets affected by this update, we do not expect it to have a material effect on our financial statements and disclosures. This update is effective for public companies for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted for the fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. 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, 2020, including interim periods within those fiscal years. Early adoption is permitted. We are currently evaluating the potential impact of the adoption of this update but do not expect it to have a material effect on our financial statements and disclosures. In August 2018, the FASB issued ASU 2018-15, Intangibles-Goodwill and Other-Internal-Use Software. This ASU requires the capitalization of implementation costs for activities performed in a cloud computing arrangement that is a service contract. The new standard aligns the accounting for implementation costs of hosting arrangements that are service contracts with the accounting for capitalizing internal-use software. This update is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. We are currently evaluating the potential impact of the adoption of this update but do not expect it to have a material effect on our financial statements and disclosures. In April 2019, the FASB issued ASU 2019-04, Codification Improvements related to Financial Instruments-Credit Losses, Derivatives and Hedging, and Financial Instruments. This update to the accounting standards regarding financial instruments and derivatives and hedging clarifies the accounting treatment for the measurement of credit losses and provides further clarification on previously issued updates. This update is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. We are currently evaluating the potential impact of the adoption of this update but do not expect it to have a material effect on our financial statements and disclosures.
Segment Reporting, Policy	We have two strategic business units that we manage separately—Mortgage Insurance and Services. Adjusted pretax operating income (loss) for each segment represents segment results on a standalone basis; therefore, inter-segment eliminations and reclassifications required for consolidated GAAP presentation have not been reflected. Inter-segment activities are recorded at market rates for segment reporting and eliminated in consolidation. We allocate to our Mortgage Insurance segment: (i) corporate expenses based on the segment’s forecasted annual percentage of total revenue, which approximates the estimated percentage of time spent on the segment; (ii) except as described below for periods prior to January 1, 2019, all interest expense; and (iii) all net investment income from corporate cash and investments. Prior to January 1, 2019, interest expense related to the Clayton Intercompany Note was allocated to our Services segment. Effective January 1, 2019, Radian Group recapitalized the Services segment with a capital contribution that enabled the Services segment to repay the Clayton Intercompany Note and its accumulated allocated interest expense associated with the note, and effective as of the same date, all interest expense is allocated to our Mortgage Insurance segment. We allocate to our Services segment: (i) corporate expenses based on the segment’s forecasted annual percentage of total revenue, which approximates the estimated percentage of time spent on the segment and (ii) until January 1, 2019, the allocated interest expense related to the Clayton Intercompany Note as discussed above.
Income Tax, Policy	We are required to establish a valuation allowance against our deferred tax assets when it is more likely than not that all or some portion of our deferred tax assets will not be realized. At each balance sheet date, we assess our need for a valuation allowance and this assessment is based on all available evidence, both positive and negative. This requires management to exercise judgment and make assumptions regarding whether our deferred tax assets will be realized in future periods.

In the event that all of the assets in the reinsurance trust (consisting of U.S. government money market funds, cash or U.S. Treasury securities) were to lose their value and the VIE is unable to make its payments to us, our maximum potential loss would be the amount of mortgage insurance claim payments for losses on the insured policies, net of the aggregate reinsurance payments already received, up to the full aggregate excess-of-loss reinsurance coverage amount. In the same scenario, the related embedded derivative would no longer have value.
