Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2025

Our consolidated financial statements are prepared in accordance with GAAP and include the accounts of Radian Group and its subsidiaries. All intercompany accounts and transactions, and intercompany profits and losses, have been eliminated. As further described in Note 3, certain prior period amounts have been reclassified to conform to the current period presentation to reflect the reclassification of certain businesses as held for sale and discontinued operations.

We generally refer to our holding company alone, without its consolidated subsidiaries, as “Radian Group.” We refer to Radian Group together with its consolidated subsidiaries as “Radian,” the “Company,” “we,” “us” or “our,” unless the context requires otherwise. Unless otherwise defined in this report, certain terms and acronyms used throughout this report are defined in the Glossary of Abbreviations and Acronyms included as part of this report.

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 consolidated financial statements include our best estimates and assumptions, actual results may vary materially.

Investments

We group fixed-maturity securities in our investment portfolio into trading or available for sale securities. Trading securities are reported at fair value, with unrealized gains and losses reported as a separate component of income. Investments in fixed-maturity securities classified as available for sale are reported at fair value, with unrealized gains and losses (net of tax) reported as a separate component of stockholders’ equity as accumulated other comprehensive income (loss).

We also invest in several other types of investments including equity securities, which primarily consist of our interests in a variety of broadly diversified exchange-traded funds and are recorded at fair value with unrealized gains and losses reported in income. Short-term investments are also carried at fair value and consist of money market instruments, certificates of deposit and highly liquid, interest-bearing instruments with an original maturity of 12 months or less at the time of purchase.

Amortization of premium and accretion of discount are calculated principally using the interest method over the term of the investment. Realized gains and losses on investments are recognized using the specific identification method. See Notes 6 and 7 for further discussion on investments.

We recognize an impairment as a loss for fixed-maturities available for sale on the consolidated statements of operations if: (i) we intend to sell the impaired security; (ii) it is more likely than not that we will be required to sell the impaired security prior to recovery of its amortized cost basis; or (iii) the present value of cash flows we expect to collect is less than the amortized cost basis of a security. In those instances, we record an impairment loss through earnings that varies depending on specific circumstances. If a sale is likely, the full amount of the impairment is recognized as a loss in the consolidated statements of operations. Otherwise, unrealized losses on securities are separated into: (i) the portion of loss that represents the credit loss and (ii) the portion that is due to other factors. In evaluating whether a decline in value for other securities relates to an existing credit loss, we consider several factors, including, but not limited to, the following:

▪

the extent to which the amortized cost basis is greater than fair value;

▪

reasons for the decline in value (e.g., adverse conditions related to industry or geographic area, changes in financial condition to the issuers or underlying loan obligors);

▪

any changes to the rating of the security by a rating agency;

▪

the failure of the issuer to make a scheduled payment;

▪

the financial position, access to capital and near-term prospects of the issuer, including the current and future impact of any specific events; and

▪

our best estimate of the present value of cash flows expected to be collected.

If a credit loss is determined to exist, the impairment amount is calculated as the difference between the amortized cost and the present value of future expected cash flows, limited to the difference between the carrying amount (i.e., fair value) and amortized cost. This credit loss impairment is included in net gains (losses) on investments and other financial instruments in the consolidated statements of operations, with an offset to an allowance for credit losses. Subsequent changes (favorable and unfavorable) in expected credit losses are recognized immediately in net income as a credit loss impairment or a reversal of credit loss impairment.

Fair Value of Financial Instruments

Our estimated fair value measurements are intended to reflect the assumptions market participants would use in pricing an asset or liability based on the best information available. Assumptions include the risks inherent in a particular valuation technique (such as a pricing model) and the risks inherent in the inputs to the model. Changes in economic conditions and capital market conditions, including but not limited to, credit spread changes, benchmark interest rate changes, market volatility and changes in the value of underlying collateral, could cause actual results to differ materially from our estimated fair value measurements. We define fair value as the current amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.

In accordance with GAAP, which establishes a three-level valuation hierarchy, we disclose fair value measurements based on the transparency of inputs to the valuation of an asset or liability as of the measurement date. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level I measurements) and the lowest priority to unobservable inputs (Level III measurements). The level in the fair value hierarchy within which the fair value measurement falls is determined based on the lowest level input that is significant to the measurement in its entirety. The three levels of the fair value hierarchy are defined below:


Level I	—	Unadjusted quoted prices for identical assets or liabilities in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;
Level II	—	Prices or valuations based on observable inputs other than quoted prices in active markets for identical assets and liabilities; and
Level III	—	Prices or valuations that require inputs that are both significant to the fair value measurement and unobservable. Level III inputs are used to measure fair value only to the extent that observable inputs are not available.

For markets in which inputs are not observable or are limited, we use significant judgment and assumptions that a typical market participant would use to evaluate the market price of an asset or liability. Given the level of judgment necessary, another market participant may derive a materially different estimate of fair value. These assets and liabilities are classified in Level III of our fair value hierarchy.

Available for sale securities, trading securities, equity securities and certain other assets and liabilities are recorded at fair value as described in Note 6. All changes in fair value of trading securities, equity securities and certain other assets and liabilities are included in our consolidated statements of operations.

Restricted Cash

Included in our restricted cash balances as of December 31, 2025 and 2024, were cash funds held in trusts for the benefit of certain counterparties, primarily as security for the payment and performance of the Company’s obligations.

Accounts and Notes Receivable

Accounts and notes receivable primarily consist of accrued premiums receivable, amounts billed and due from our customers for services performed, and certain receivables related to our reinsurance transactions. Accounts and notes receivable are carried at their estimated collectible amounts, net of any allowance for doubtful accounts, and are periodically evaluated for collectability based on past payment history and current economic conditions. See “Revenue Recognition” below for information on our deferred premiums and Note 8 for details on our reinsurance agreements.

We have no material bad-debt expense.

Reinsurance

We cede insurance risk through the use of reinsurance contracts and follow reinsurance accounting for those transactions where significant risk is transferred. Loss reserves and unearned premiums are established before consideration is given to amounts related to our reinsurance agreements.

In accordance with the terms of certain agreements under our QSR Program, rather than making a cash payment or transferring investments for ceded premiums written, Radian Guaranty holds the related amounts to collateralize the reinsurers’ obligations and has established a corresponding funds withheld liability. Any loss recoveries and any potential profit commission to Radian Guaranty will be realized from this account. The reinsurers’ share of earned premiums is paid from this account on a quarterly basis. For our Single Premium QSR Program, this liability also includes an interest credit on funds withheld, which is recorded as ceded premiums at a rate specified in the agreement and, depending on experience under the contract, may be paid to either Radian Guaranty or the reinsurers.

The ceding commission earned for premiums ceded pursuant to this transaction is attributable to other underwriting costs (including any related deferred policy acquisition costs). The unamortized portion of the ceding commission in excess of our related acquisition cost is reflected in other liabilities. Ceded premiums written are recorded on the balance sheet as prepaid reinsurance premiums and amortized to ceded premiums earned in a manner consistent with the recognition of income on direct premiums. See Note 8 for further discussion of our reinsurance transactions.

Variable Interest Entity

In connection with our reinsurance programs for our Mortgage Insurance business, we may enter into contracts with VIEs. VIEs include corporations, trusts or partnerships in which: (i) the entity has insufficient equity at risk to allow it to finance its activities without additional subordinated financial support or (ii) at-risk equity holders, as a group, do not have the characteristics of a controlling financial interest.

We perform an evaluation to determine whether we are required to consolidate the VIE’s assets and liabilities in our consolidated financial statements, based on whether we are deemed to be the primary beneficiary. The primary beneficiary of a VIE is the variable interest holder that is determined to have the controlling financial interest as a result of having both: (i) the power to direct the activities of a VIE that most significantly impact the economic performance of the VIE and (ii) the obligation to absorb losses or right to receive benefits from the VIE that potentially could be significant to the VIE. See Note 8 for additional information.

Deferred Policy Acquisition Costs

Incremental, direct costs associated with the successful acquisition of mortgage insurance policies, consisting of compensation, premium tax and other policy issuance and underwriting expenses, are initially deferred and reported as deferred policy acquisition costs. Consistent with industry accounting practice, amortization of these costs for each underwriting year is recognized in proportion to estimated gross profits over the estimated life of the policies.

Estimates of expected gross profit are primarily influenced by loss development assumptions, which are used as a basis for amortization and evaluated periodically. The total amortization recorded to date is adjusted by a charge or credit to our consolidated statements of operations if actual experience or other evidence suggests that previous estimates should be revised. Considerable judgment is used in evaluating these estimates and the assumptions on which they are based. The use of different assumptions may have a significant effect on the amortization of deferred policy acquisition costs.

Ceding commissions received under our reinsurance arrangements related to these costs are also deferred and accounted for using similar assumptions. See Note 8 for additional information.

Property and Equipment, Net

We capitalize certain costs associated with the development of internal-use software and the purchase of property and equipment. Software, property and equipment are carried at cost, net of accumulated depreciation and amortization. Amortization and depreciation are calculated on a straight-line basis over the estimated useful life of the respective assets and commence during the month of our placement of the assets into use.

The estimated useful life used to calculate the amortization of internal-use software is generally seven years. Leasehold improvements are depreciated over the lesser of the estimated useful life of the asset improved or the remaining term of the lease. The estimated useful life used to calculate the depreciation of furniture and equipment is generally three years. Depreciation and amortization expense associated with property and equipment for the years ended December 31, 2025, 2024 and 2023, was $10 million, $15 million and $12 million, respectively.

The following is a summary of the gross and net carrying amounts and accumulated amortization / depreciation (including impairment) of our property and equipment as of the periods indicated.


Property and equipment

	December 31, 2025							December 31, 2024
(In thousands)	Gross Carrying Amount		Accumulated Amortization / Depreciation			Net Carrying Amount		Gross Carrying Amount		Accumulated Amortization / Depreciation			Net Carrying Amount

Leases

We determine if an arrangement includes a lease at inception, and if it does, we recognize a right-of-use asset and lease liability. 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 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.

Lease expense is recognized on a straight-line basis over the expected lease term. Lease and non-lease components are generally not accounted for separately.

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.

We assess our various asset groups, which include right-of-use assets, for changes in grouping and for potential impairment when certain events occur or when there are changes in circumstances, including potential alternative uses. If circumstances require a change in asset groupings or a right-of-use asset to be tested for possible impairment, and the carrying value of the right-of-use asset is not recoverable on an undiscounted cash flow basis, an impairment is recognized to the extent that the carrying value exceeds its fair value. See Note 13 for additional information on our leases.

Held for Sale Classification

We report a business as held for sale when management has committed to a formal plan to sell the assets, the business is available for immediate sale and is being actively marketed at a price that is reasonable in relation to its fair value, an active program to locate a buyer and other actions required to complete the plan to sell the asset have been initiated, the sale is probable and expected to be completed within one year, and it is deemed unlikely that significant changes to the plan will be made or that the plan will be withdrawn. A business classified as held for sale is reflected at the lower of its carrying amount or estimated fair value less cost to sell. If the carrying amount of the business exceeds its estimated fair value, a loss is recognized. Assets and liabilities related to a business classified as held for sale are segregated in the consolidated balance sheets in the period in which the business is classified as held for sale and any prior periods presented. After a business is classified as held for sale, depreciation and amortization expense is not recognized on its assets. See Note 3 for additional details about our held for sale assets and liabilities.

Reserve for Losses and LAE

Mortgage Insurance

We establish reserves to provide for losses and LAE on our mortgage insurance policies, which include the estimated costs of settling claims, in accordance with the accounting standard regarding accounting and reporting by insurance enterprises (ASC 944). Although this standard specifically excludes mortgage insurance from its guidance relating to the reserve for losses, because there is no specific guidance for mortgage insurance, we establish reserves for mortgage insurance as described below, using the guidance contained in this standard supplemented with other accounting guidance.

In our Mortgage Insurance business, the default and claim cycle begins with the receipt of a default notice from the loan servicer. Case reserves for losses are established upon receipt of notification from servicers that a borrower has missed two monthly payments, which is when we consider a loan to be in default for financial statement and internal tracking purposes. We also establish reserves for associated LAE, consisting of the estimated cost of the claims administration process, including legal and other fees and expenses associated with administering the claims process.

We do not establish reserves for loans that are in default if we believe that we will not be liable for the payment of a claim with respect to that default. We generally do not establish loss reserves for expected future claims on insured mortgages that are not in default. See “Reserve for Premium Deficiency” below for an exception to these general principles.

With respect to loans that are in default, considerable judgment is exercised as to the adequacy of reserve levels. We use an actuarial projection methodology referred to as a “roll rate” analysis that uses historical claim frequency information to determine the projected ultimate Default to Claim Rates based on the Stage of Default and Time in Default as well as the date that a loan goes into default. The Default to Claim Rate also includes our estimates with respect to expected Loss Mitigation Activities, which have the effect of reducing our Default to Claim Rates.

After estimating the Default to Claim Rate, we estimate Claim Severity by applying observed severity rates for past paid claims within cohorts based on both Time in Default and estimated borrower equity, as adjusted to account for anticipated differences and risks in future results compared to past trends, including potential declines in estimated borrower equity. These severity estimates are then applied to individual loan coverage amounts to determine reserves.

Rescissions, Claim Denials and Claim Curtailments may occur for various reasons, including, without limitation, underwriting negligence, fraudulent applications and appraisals, breach of representations and warranties and inadequate documentation, primarily related to our insurance written in years prior to and including 2008. For our Loss Mitigation Activities, we incorporate a process referred to as a claims rebuttal process by which the insured or servicer of loans may challenge our decisions. Our estimate of future Loss Mitigation Activities incorporates our estimates of the likely outcomes of our claims rebuttal process based on historical practices.

Estimating our case reserve for losses involves significant reliance upon assumptions and estimates with regard to the likelihood, magnitude and timing of each potential loss. The models, assumptions and estimates we use to establish loss reserves may not prove to be accurate, especially in the event of an extended economic downturn or a period of market volatility and economic uncertainty. These assumptions require management to use considerable judgment in estimating the rate at which these loans will result in claims and the amount of claims we expect to pay. As such, there is uncertainty around our reserve estimate.

Reserve for Premium Deficiency

Insurance enterprises are required to establish a premium deficiency reserve if the net present value of the expected future losses and expenses for a particular product line exceeds the net present value of expected future premiums and existing reserves for that product line. We reassess our expectations for premiums, losses and expenses for our Mortgage Insurance business at least quarterly and update our premium deficiency analyses accordingly.

We did not require a premium deficiency reserve as of December 31, 2025 or 2024.

Revenue Recognition

Premiums on mortgage insurance products are written on a recurring basis, either as monthly or annual premiums, or on a multi-year basis as a single premium. Monthly premiums written are earned as coverage is provided each month. For certain monthly policies where the billing was deferred for the first month’s coverage period, we have recorded a net premium receivable representing the present value of such deferred premiums that we estimate will be collected at a future date. Prior to January 1, 2026, the billing for such deferred premiums occurred at the end of the policy. We recently implemented an operational change for all new monthly premium policies written, effective January 1, 2026, where the billing for the first full month of coverage will occur at the start of the policy and is aligned to the first mortgage payment due on the loan. This change has no material impact to overall premiums billed or collected and simply changes the timing of the earning of any deferred premium. As of December 31, 2025 and 2024, our net deferred premium receivable was $40 million and $38 million, respectively, representing the present values of $86 million and $83 million, respectively, in contractual deferred monthly premiums, after adjustments for the estimated collectability and timing of future billing. We recognize changes in this receivable based on changes in the estimated amount and timing of such collections, including as a result of changes in observed trends as well as our periodic review of our servicing guide and our operations and collections practices.

Annual premiums written are initially recorded as unearned premiums and amortized on a monthly, straight-line basis. Single premiums written are initially recorded as unearned premiums and earned over time based on the anticipated claim payment pattern, which includes historical industry experience and is updated periodically.

When we rescind insurance coverage on a loan, we refund all premiums received in connection with such coverage. When insurance coverage on a loan is canceled due to claim payment, we refund all premiums received since the date of delinquency. When insurance coverage is canceled for a reason other than Rescission or claim payment, all premium that is nonrefundable is immediately earned. Premium revenue is recognized net of our accrual for estimated premium refunds due to Rescissions, claim payments or other factors.

With respect to our reinsurance transactions, ceded premiums written on an annual or multi-year basis are initially set up as prepaid reinsurance and are amortized in a manner consistent with the recognition of income on direct premiums.

Share-Based Compensation

The cost related to share-based equity instruments is measured based on the grant-date fair value at the date of issuance, which for RSU awards is primarily determined by our common stock price on the date of grant. For share-based awards with performance conditions related to our own operations, the grant-date fair value and expense recognized is dependent on the probability of the performance measure being achieved. Compensation cost is generally recognized over the periods that an employee provides service in exchange for the award. Any forfeitures of awards are recognized as they occur. See Note 17 for further information.

Discontinued Operations

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

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

Income Taxes

We provide for income taxes in accordance with the provisions of the accounting standard regarding accounting for income taxes. As required under this standard, our deferred tax assets and deferred tax liabilities are recognized under the balance sheet method, which recognizes the future tax effect of temporary differences between the amounts recorded in our consolidated financial statements and the tax bases of these amounts. Deferred tax assets and deferred tax liabilities are measured using the enacted tax rates that are expected to apply to taxable income in the periods in which the deferred tax asset or deferred tax liability is expected to be realized or settled. In regard to accumulated other comprehensive income, the Company’s policy for releasing disproportionate income tax effects is to release the effects as individual items are sold. Our policy for the recognition of interest and penalties associated with uncertain tax positions is to record such items as a component of our income tax provision.

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. Our 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.

See Note 10 for further discussion on income taxes.

Earnings 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 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 primarily to our share-based compensation arrangements. In computing diluted net income per share, we use the treasury stock method, which is computed by assuming the issuance of common stock for the potential dilution of our unvested RSUs. For all calculations, the determination of whether potential common shares are dilutive or anti-dilutive is based on net income.

Recent Accounting Pronouncements

Accounting Standards Adopted During 2025

In December 2023, the FASB issued ASU 2023-09, Income Taxes—Improvements to Income Tax Disclosures, an update which enhances income tax disclosures. This guidance requires disaggregated information about an entity’s effective tax rate reconciliation as well as information on income taxes paid. This update is applicable to all public entities and is effective for fiscal years starting after December 15, 2024. We applied the amendments in this update retrospectively and the adoption of this guidance did not have a material impact on our disclosures. See Note 10 for additional required disclosures.

Accounting Standards Not Yet Adopted

In November 2024, the FASB issued ASU 2024-03, Disaggregation of Income Statement Expenses. This update requires enhanced disclosures of certain costs and expenses in the notes to the financial statements. This update is applicable

to all public entities and is effective for fiscal years beginning after December 15, 2026, and interim periods beginning after December 15, 2027. Early adoption is permitted. The amendments in this update should be applied prospectively; however, retrospective application is permitted. We are currently evaluating the impact the new accounting guidance will have on our disclosures.

In September 2025, the FASB issued ASU 2025-06, Intangibles-Goodwill and Other-Internal-Use Software: Targeted Improvements to the Accounting for Internal-Use Software, which introduces a principles-based approach for determining when costs can be capitalized. Entities are required to start capitalizing software costs when management has authorized and committed to funding the software project, it is probable the project will be completed, and the software will be used to perform the function intended (referred to as the “probable-to-complete recognition threshold”). This update is effective for fiscal years beginning after December 15, 2027, and interim periods within those annual reporting periods. Early adoption is permitted as of the beginning of an annual reporting period. Adoption is permitted prospectively, retrospectively, or using a modified approach that is based on the status of the project and whether software costs were capitalized before the date of adoption. We are currently evaluating the impact the new accounting guidance will have on our consolidated financial statements.
