All statements in this report that address events, developments or results that we expect or anticipate may occur in the future are “forward-looking statements” within the meaning of Section 27A of the Securities Act, Section 21E of the Exchange Act and the Private Securities Litigation Reform Act of 1995. In most cases, forward-looking statements may be identified by words such as “anticipate,” “may,” “will,” “could,” “should,” “would,” “expect,” “intend,” “plan,” “goal,” “contemplate,” “believe,” “estimate,” “predict,” “project,” “potential,” “continue,” “seek,” “strategy,” “future,” “likely” or the negative or other variations on these words and other similar expressions. These statements, which may include, without limitation, projections regarding our future performance and financial condition, are made on the basis of management’s current views and assumptions with respect to future events, including management’s current views regarding the likely impacts of the COVID-19 pandemic. Any forward-looking statement is not a guarantee of future performance and actual results could differ materially from those contained in the forward-looking statement. These statements speak only as of the date they were made, and we undertake no obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise. We operate in a changing environment where new risks emerge from time to time and it is not possible for us to predict all risks that may affect us, particularly those associated with the COVID-19 pandemic, which has had wide-ranging and continually evolving effects. The forward-looking statements are not guarantees of future performance, and the forward-looking statements, as well as our prospects as a whole, are subject to risks and uncertainties that could cause actual results to differ materially from those set forth in the forward-looking statements. These risks and uncertainties include, without limitation:

For more information regarding these risks and uncertainties as well as certain additional risks that we face, you should refer to “Item 1A. Risk Factors” in this report and “Item 1A. Risk Factors” in our 2020 Form 10-K, and to subsequent reports and registration statements filed from time to time with the SEC. We caution you not to place undue reliance on these forward-looking statements, which are current only as of the date on which we issued this report.

We are a diversified mortgage and real estate business, providing both credit-related mortgage insurance coverage and a broad array of other mortgage, risk, title, valuation, asset management, SaaS and other real estate services. We have 2 reportable business segments—Mortgage and Real Estate.homegenius. Our homegenius segment was previously named “Real Estate” and during the second quarter of 2021 we renamed it “homegenius” to align with updates to our branding strategy for the segment’s products and services.

Our Mortgage segment provides credit-related insurance coverage, principally through private mortgage insurance on residential first-lien mortgage loans, as well as other credit risk management, and contract underwriting and fulfillment 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 and investors, as well as 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 $238.9$237.3 billion and $58.5$58.0 billion, respectively, as of March 31,June 30, 2021, compared to $246.1 billion and $60.7 billion, respectively, as of December 31, 2020. In addition to providing private mortgage insurance, we participate in credit risk transfer programs developed by the GSEs as part of their initiative to distribute mortgage credit risk and increase the role of private capital in the mortgage market. Our additional RIF under credit risk transfer transactions, resulting from our participation in these programs with the GSEs, totaled $428.8$434.7 million as of March 31,June 30, 2021 compared to $392.0 million as of December 31, 2020.

The GSEs and state insurance regulators impose various capital and financial requirements on our mortgage insurance subsidiaries. These include Risk-to-capital, other risk-based capital measures and surplus requirements, as well as the PMIERs financial requirements. Failure to comply with these capital and financial requirements may limit the amount of insurance that our mortgage insurance subsidiaries write or may prohibit them from writing insurance altogether. The GSEs and state insurance regulators possess significant discretion with respect to our mortgage insurance subsidiaries and all aspects of their business. See Note 16 for additional information on PMIERs and other regulatory information, and “—Recent Developments” below for a discussion of the elevated risks posed by the COVID-19 pandemic, which has led to an increase in mortgage defaults in our insured portfolio and a resulting increase in our Minimum Required Assets.

Our Real Estatehomegenius segment is primarily a fee-for-service business that offers a broad array of products and services to market participants across the real estate value chain. Our real estatehomegenius products and services include title, valuation, asset management, SaaS and other real estate services offered primarily to mortgage lenders, mortgage and real estate investors, GSEs, real estate brokers and agents. These products and services help lenders, investors, consumers and real estate agents evaluate, manage, monitor, acquire and sell properties. These products and services include software as a serviceSaaS solutions and platforms, as well as managed services, such as real estate owned asset management, single family rental services and real estate valuation services. In addition, we provide title insurance and non-insurance title, closing and settlement services to mortgage lenders, GSEs and mortgage investors, as well as directly to consumers for residential mortgage loans.

See Note 4 for additional information about our reportable segments and All Other business activities.

As a seller of mortgage credit protection, our results are subject to macroeconomic conditions and specific events that impact the housing finance and real estate markets, including events that impact mortgage originations and the credit performance of our RIF. Many of these conditions are beyond our control, including housing prices, unemployment, interest rate changes, the availability of credit and other factors that may be derived from national and regional economic conditions. In general, a deterioration in economic conditions increases the likelihood that borrowers will be unable to satisfy their mortgage obligations. A deteriorating economy can adversely affect housing values, which in turn can influence the willingness of borrowers to continue to make mortgage payments regardless of whether they have the financial resources to do so. Mortgage defaults can also occur due to a variety of specific events affecting borrowers, including death or illness, divorce or other family problems, unemployment, or other events. In addition, factors impacting regional economic conditions, acts of terrorism, war or other severe conflicts, event-specific economic depressions or other catastrophic events such as natural disasters and pandemics could result in increased defaults due to the impact of such events on the ability of borrowers to satisfy their mortgage obligations and on the value of affected homes.

The unprecedented and continually evolving social and economic impacts associated with the COVID-19 pandemic on the U.S. and global economies generally, and in particular on the U.S. housing, real estate and housing finance markets, had a negative effect on our business and our financial results for the second quarter of 2020, and to

We expect that certain future developments, such as anticipated increases in our claims paid once current foreclosure moratoriums are lifted, will have an adverse impact on aspects of our business in future periods. The long-term impact of the COVID-19 pandemic on our businesses will depend on, among other things: the extent and duration of the pandemic, the severity of illness and number of people infected with the virus and the acceptance and long-term effectiveness of anti-viral treatments and vaccines, especially as new strains of COVID-19 have been discovered;emerged; the wider economic effects of the pandemic and the scope and duration of governmental and other third-party measures restricting day-to-day life and business operations; the impact of economic stimulus efforts to support the economy through the pandemic; and governmental and GSE programs implemented to assist borrowers experiencing a COVID-19-related hardship, including forbearance programs and suspensions of foreclosures and evictions. Although we are uncertain of the potential magnitude or duration of the business and economic impacts of the COVID-19 pandemic, these and other factors, including those discussed in our 2020 Form 10-K, could continue to have a material negative effect on the Company’s business, liquidity, results of operations and financial condition.

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 (loss) 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 2020 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. See Note 1 for discussion of the elevated risks to our future business, liquidity, results of operations and financial condition due to the COVID-19 pandemic.

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.

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.

See Note 2 of Notes to Consolidated Financial Statements in our 2020 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 2020 Form 10-K, other than described below in “—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.

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.

Basic net income (loss) per share is computed by dividing net income (loss) by the weighted-average number of common shares outstanding, while diluted net income (loss) per share is computed by dividing net income (loss) 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 (loss) per share is as follows.

We have 2 strategic business units that we manage separately—Mortgage and Real Estate.homegenius. Our Mortgage segment derives its revenue from mortgage insurance and other mortgage and risk services, including contract underwriting servicesand fulfillment solutions provided to lenders.mortgage lending institutions and mortgage credit investors. Our Real Estatehomegenius segment offers a broad array of title, valuation, asset management, SaaS and other real estate services to market participants across themortgage lenders, mortgage and real estate value chain.investors, GSEs, real estate brokers and agents. In addition, we report as All Other activities that include: (i) income (losses) from assets held by our holding company; (ii) related general corporate operating expenses not attributable or allocated to our reportable segments; (iii) for all periods through its sale in January 2020, income and expenses related to Clayton; (iv) for all periods presented, the income and expenses related to our traditional appraisal services, which we wound down beginning in the fourth quarter of 2020; and (v) certain other immaterial revenue and expense items.

As described in Note 4 of Notes to Consolidated Financial Statements in our 2020 Form 10-K, we implemented several changes to our segment reporting in 2020, including related to the wind down of our traditional appraisal business announced in the fourth quarter of 2020. All changes to the composition of our segment reporting have been reflected in our segment operating results for all periods presented. See Note 1 for additional details about

During the second quarter of 2021, our Mortgage and Real Estate businesses.segment was renamed “homegenius” to align with updates to our branding strategy for the segment’s products and services. The homegenius segment name change had no impact on the composition of our segments or on our previously reported historical financial position, results of operations, cash flow or segment level results.

We allocate corporate operating expenses to both reportable segments based on each segment’s forecasted annual percentage of total revenue, which approximates the estimated percentage of management time spent on each segment. In addition, we allocate all corporate interest expense to our Mortgage segment, due to the capital-intensive nature of our mortgage insurance business.

With the exception of goodwill and other acquired intangible assets that relate to our Real Estatehomegenius segment, which are reviewed as part of our annual goodwill impairment assessment, we do not manage assets by segment.

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 impairment of internal-use software, gains (losses) from the sale of lines of business and acquisition-related income and expenses. See Note 4 of Notes to Consolidated Financial Statements in our 2020 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 revenue for our reportable segments to consolidated revenues is as follows.

For discussion of our valuation methodologies for assets and liabilities measured at fair value and the fair value hierarchy, see Note 5 of Notes to Consolidated Financial Statements in our 2020 Form 10-K.
