changes in the current housing finance system in the United States, including the roles of the FHA, the GSEs and private mortgage insurers in this system;
our ability to successfully execute and implement our capital plans, including our risk distribution strategy through the capital markets and traditional reinsurance markets, and to maintain sufficient holding company liquidity to meet our liquidity needs;

the possibility that we may fail to estimate accurately, especially in the event of an extended economic downturn or a period of extreme market volatility and economic uncertainty, the likelihood, magnitude and timing of losses in establishing loss reserves for our mortgage insurance business or to accurately calculate and/or project our Available Assets and Minimum Required Assets under the PMIERs, which will be impacted by, among other things, the size and mix of our IIF, the level of defaults in our portfolio, the reported status of defaults in our portfolio, including whether they are subject to mortgage forbearance, a repayment plan or a loan modification trial period granted in response to a financial hardship related to COVID-19, the level of cash flow generated by our insurance operations and our risk distribution strategies;

Summary of Risk Factors
Our business is subject to a number of risks, including risks that may prevent us from achieving our business objectives or may adversely affect our business, financial condition, results of operations, cash flows, and prospects. These risks are discussed more fully under “Item 1A. Risk Factors” of this Annual Report on Form 10-K and include, but are not limited to, the following material risks and uncertainties:
Risks Related to the COVID-19 Pandemic
The COVID-19 pandemic adversely impacted us and, in the future, could again adversely affect our business, results of operations or financial condition.
Risks Related to Regulatory Matters
Radian Guaranty may fail to maintain its eligibility status with the GSEs, and the additional capital required to support Radian Guaranty’s eligibility could reduce our available liquidity.
Our insurance subsidiaries are subject to comprehensive state insurance regulations and other requirements, which we may fail to satisfy.
Changes in the charters, business practices or role of the GSEs in the U.S. housing market generally, could significantly impact our businesses.
Legislation and administrative and regulatory changes and interpretations could impact our businesses.
Risks Related to our Mortgage and homegenius Business Operations
Our success depends on our ability to assess and manage our underwriting risks; the premiums we charge may not be adequate to compensate us for our liability for losses and the amount of capital we are required to hold against our insured risks. We expect to incur losses for future defaults beyond what we have reserved for in our financial statements.
If the estimates we use in establishing loss reserves are incorrect, we may be required to take unexpected charges to income, which could adversely affect our results of operations.
Our Loss Mitigation Activity is not expected to mitigate mortgage insurance losses to the same extent as in prior years; Loss Mitigation Activity could continue to negatively impact our customer relationships.
Reinsurance may not be available, affordable or adequate to protect us against losses.
An extension in the period of time that a loan remains in our defaulted loan inventory may increase the severity of claims that we ultimately are required to pay.
If the length of time that our mortgage insurance policies remain in force declines, it could result in a decrease in our future revenues.
Our delegated underwriting program may subject our mortgage insurance business to unanticipated claims.
Our mortgage insurance business faces intense competition.
Our NIW and franchise value could decline if we lose business from significant customers.
The current financial strength ratings assigned to our mortgage insurance subsidiaries could weaken our competitive position and potential downgrades by rating agencies to these ratings and the ratings assigned to Radian Group could adversely affect the Company.
Our business depends, in part, on effective and reliable loan servicing.
We face risks associated with our contract underwriting business.
A decrease in the volume of mortgage originations could result in fewer opportunities for us to write new mortgage insurance business and conduct our homegenius business.
We are exposed to risks associated with our homegenius business that could negatively affect our results of operations and financial condition.
We rely upon proprietary technology and information, and if we are unable to protect our intellectual property rights, it could have a material adverse effect on us.
10

Risks Related to the Economic Environment
The credit performance of our mortgage insurance portfolio is impacted by macroeconomic conditions and specific events that affect the ability of borrowers to pay their mortgages.
Our success depends, in part, on our ability to manage risks in our investment portfolio.
Climate change and extreme weather events could adversely affect our businesses, results of operations and financial condition.
Our reported earnings, stockholders’ equity and book value per share are subject to fluctuations based on changes in our investments that require us to adjust their fair market value.
The discontinuance of LIBOR may adversely affect us.
Risks Related to Liquidity and Financing
Radian Group’s sources of liquidity may be insufficient to fund its obligations.
Our revolving credit facility contains restrictive covenants that could limit our operating flexibility. A default under our credit facility could trigger an event of default under the terms of our senior notes. We may not have access to funding under our credit facility when we require it.
Risks Related to Information Technology and Cybersecurity
Our information technology systems may fail or become outmoded, be temporarily interrupted or otherwise cause us to be unable to meet our customers’ demands.
We could incur significant liability or reputational harm if the security of our information technology systems is breached, including as result of a cyberattack, or we otherwise fail to protect confidential information, including personally identifiable information that we maintain.
Risks Related to Us and Our Subsidiaries Generally
We may not continue to pay dividends at the same rate we are currently paying them, or at all, and any decrease in or suspension of payment of a dividend could cause our stock price to decline.
We are subject to litigation and regulatory proceedings.
We rely on our management team and our business could be harmed if we are unable to retain qualified personnel or successfully develop and/or recruit their replacements.
Investments to grow our existing businesses, pursue new lines of business or new products and services within existing lines of business subject us to additional risks and uncertainties.

General
Overview
We are a diversified mortgage and real estate services business. We provide mortgage insurance and other products and services to the real estate and mortgage finance industries through our two business segments—Mortgage and homegenius. While we manage and report on these two segments separately, we take an enterprise approach under our “One Radian” strategy, which leverages the value of our employees across our diversified businesses to better serve our customers.
Our Mortgage segment aggregates, manages and distributes U.S. mortgage credit risk on behalf of mortgage lending institutions and mortgage credit investors, principally through private mortgage insurance on residential first-lien mortgage loans, and also provides other credit risk management, contract underwriting and fulfillment solutions to our customers. Our homegenius segment offers an array of title, real estate and technology products and services to consumers, mortgage lenders, mortgage and real estate investors, GSEs and real estate brokers and agents. See Notes 1 and 4 of Notes to Consolidated Financial Statements for further details of our businesses, including the renaming of the homegenius segment in 2021 to align with updates to our brand strategy.
Radian Group serves as the holding company for our insurance and other subsidiaries, through which we offer our products and services, and does not have any operations of its own. Our principal executive offices are located at 550 East Swedesford Road, Suite 350, Wayne, PA 19087, and our telephone number is (215) 231-1000.

In pursuing these objectives, we expect to increase value creation for our stakeholders.
Consistent with these objectives, our business strategy, as highlighted below, is focused on growing our businesses, diversifying our revenue sources and seeking to optimize our capital and liquidity, while maintaining an emphasis on risk management, human capital management and long-term profitability. To help achieve these objectives, we seek to continuously improve and leverage our operational excellence and the strength of our “One Radian” brand.
A key element of our business strategy is to complement and diversify our business and revenue streams by increasing our participation in multiple facets of the residential real estate and mortgage finance markets while also building competitive differentiation within our Mortgage business. Under our homegenius brand, we are focused on growing our homegenius businesses to meet increased market demand for digital products and services across our title, real estate and technology business platforms. See “homegenius—homegenius Business Overview” for additional information about our homegenius business. With respect to our Mortgage business, we continue to seek and develop new and innovative opportunities to build upon our core mortgage credit risk competencies by expanding our mortgage market presence and further diversifying our revenue streams.
Radian’s Long-Term Strategic Objectives
Grow and diversify our Mortgage and homegenius businesses through innovative business models that leverage the strength of our One Radian brand and the value of operating excellence to:
Continue to grow the economic value of our insured mortgage portfolio by writing profitable NIW
Leverage our industry knowledge, core competencies and strong market position to develop opportunities to expand our mortgage market presence
Build the homegenius brand and continue to position our title, real estate and technology products and services for long-term growth in revenues and value contribution
Continue to expand our Mortgage and homegenius market presence by leveraging the value of our One Radian enterprise sales relationships and our multi-channel marketing model
Further utilize the quality, performance and scale of our operations and delivery of products and services as a strategic and competitive differentiator
Maintain strong comprehensive enterprise risk management and risk/return discipline based on sound data and analytics
Optimize our capital and liquidity position to ensure ongoing compliance with PMIERs, build strategic financial flexibility to support our growth and diversification plans and increase stockholder value
Strengthen our One Radian team by building upon our inclusiveness and diversity, developing our talent for future success, fostering a culture based on our values and mission and utilizing data and analytics to adapt for the future
In our mortgage insurance business, we evaluate the projected long-term economic value of our insured portfolio by using a measure that incorporates expected lifetime returns for our insurance policies, taking into consideration projected premiums, credit losses, investment income, operating expenses, taxes and an assumed cost of capital. This projected economic value is then discounted to arrive at an estimated present value of the long-term economic value of our insured portfolio. We use this economic value to assist us in evaluating various portfolio strategies and identify opportunities to create stockholder value. See “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Mortgage Insurance Portfolio” for more information about our insured portfolio.

Mortgage
Mortgage Business Overview
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 such as the GSEs, by mitigating default-related losses on residential mortgage loans. Generally, these loans are made to home buyers 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 loans in the secondary mortgage market, most of which are currently sold to the GSEs.
The performance of our Mortgage business is particularly influenced by 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 mortgage insurance portfolio, most of which are beyond our control, including housing prices, inflationary pressures, unemployment levels, interest rate changes, the availability of credit and other national and regional economic conditions. In Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations, see “Results of Operations—Mortgage” and “Key Factors Affecting Our Results—Mortgage.”
Our Mortgage business is subject to comprehensive regulation by federal and state regulatory authorities and the GSEs. As the largest purchasers of conventional mortgage loans, and therefore, the main beneficiaries of private mortgage insurance, the GSEs impose eligibility requirements, known as PMIERs, that private mortgage insurers must satisfy in order to be approved to insure loans purchased by the GSEs. These requirements and practices, as well as those of the federal regulators that oversee the GSEs and lenders, impact the operating results and financial performance of private mortgage insurers. See “Regulation” for a comprehensive description of the significant state and federal regulations and other requirements of the GSEs that are applicable to our businesses.
Mortgage Insurance Products
Primary Mortgage Insurance
We generally provide Primary Mortgage Insurance on an individual loan basis as each mortgage is originated, but we also can provide Primary Mortgage Insurance on individual loans in an aggregate group of mortgages after they have been originated. We primarily write insurance in a “first loss” position, where we are responsible for the first losses incurred on an insured loan subject to a policy limit. See “—Mortgage Insurance Portfolio Characteristics—Mortgage Loan Characteristics.
The terms of our Primary Mortgage Insurance coverage are set forth in a Master Policy that we enter into with each of our customers. Among other things, our Master Policies set forth the applicable terms and conditions of our mortgage insurance coverage, including among others: loan eligibility requirements; premium payment requirements; coverage terms, including cancellation of coverage; provisions for policy administration; mortgage servicing standards and requirements; exclusions or reductions in coverage under certain circumstances; insurance rescission and rescission relief provisions; claims payment and settlement procedures; and dispute resolution procedures. Our Master Policy forms, which are updated periodically, including in response to requirements issued by the GSEs, are filed in each of the jurisdictions in which we conduct business. Our Master Policy form was last updated on a broad basis in 2020, when most private mortgage insurers adopted a uniform master policy. See “—Defaults and Claims—Claims Management—Rescissions.”
Primary Mortgage Insurance provides protection against mortgage defaults at a specified coverage percentage. When there is a valid claim under Primary Mortgage Insurance, the maximum liability is determined by multiplying the claim amount, which consists of the unpaid loan principal, plus past due interest and certain expenses associated with the default, by the coverage percentage. Claims may be settled for the maximum liability or for other amounts. See “—Defaults and Claims—Claims Management” below. Although the Primary Mortgage Insurance we write protects lenders from a portion of losses resulting from mortgage defaults, it generally does not provide protection against property loss or physical damage, including damage caused by hurricanes or other severe weather events or natural disasters.
We wrote $91.8 billion and $105.0 billion of first-lien Primary Mortgage Insurance in 2021 and 2020, respectively. Substantially all of our Primary Mortgage Insurance written during 2021 and 2020 was written on a Flow Basis. After taking into consideration insurance cancellations and other adjustments within our existing portfolio, our 2021 NIW resulted in IIF of $246.0 billion at December 31, 2021, compared to $246.1 billion at December 31, 2020. Our total direct Primary Mortgage Insurance RIF was $60.9 billion at December 31, 2021, compared to $60.7 billion at December 31, 2020.

Part I. Item 1. Business
Other Mortgage Insurance Products
GSE Credit Risk Transfer. Part of our business strategy includes leveraging our core expertise in credit risk management to expand our presence in the mortgage finance industry, including by pursuing alternatives to traditional mortgage insurance execution to expand our insured portfolio of mortgage credit. We have in the past and may in the future participate in credit risk transfer programs developed by the GSEs as part of their programs to further distribute mortgage credit risk and increase the role of private capital in the mortgage market. These programs transfer additional credit risk, on an excess of loss basis, to insurance and reinsurance providers on pools of mortgage loans, which may contain loans that are already covered by private mortgage insurance. Our total RIF under these credit risk transfer transactions was $417.7 million as of December 31, 2021, compared to $392.0 million as of December 31, 2020.
Given the remote nature of this risk, we will not experience claims under these credit risk transfer transactions unless the borrower’s equity in the home, any existing private mortgage insurance (if applicable and which could be provided by us) and the GSEs’ retained risk are first depleted. Through our participation in these GSE transactions, we assume additional types of risk (beyond that which we typically cover in our traditional mortgage insurance business) associated with the risk of defaults caused by physical damage, including natural disasters such as hurricanes and wildfires, which generally are not covered by the underlying private mortgage insurance. In addition to the projected returns we may achieve on this business, we regularly evaluate this exposure, including the geographic diversity of the loans included in these transactions and the protection provided by the GSEs’ first-loss risk position, in assessing our participation in these transactions. Based on our view of the projected returns on this business, including consideration of the collateral and capital required by the GSEs to support this RIF, we discontinued our participation in the GSEs’ credit risk transfer transactions in 2021, but we could resume our participation in these transactions in the future.
Pool Mortgage Insurance. Prior to 2008, we wrote Pool Mortgage Insurance on a limited basis. At December 31, 2021, our total direct first-lien Pool Mortgage Insurance RIF was $245.5 million, as compared to $281.0 million at December 31, 2020, and represented less than 1% of our total direct first-lien insurance RIF. With respect to our Pool Mortgage Insurance, an aggregate exposure limit, or “stop loss” (usually between 1% and 10%), is generally applied to the initial aggregate loan balance on a group or “pool” of mortgages. In addition, an insured pool of mortgages may contain mortgages that are already covered by Primary Mortgage Insurance. In these transactions, Pool Mortgage Insurance is secondary to any Primary Mortgage Insurance that exists on mortgages within the pool. Our Pool Mortgage Insurance policies are privately negotiated and are separate from the Master Policies that we use for our Primary Mortgage Insurance.
Pricing
Primary Mortgage Insurance Premiums
We apply premium rates to our insurance coverage at the time coverage is requested by our lender customers, which is generally near the time of loan origination. Premiums for our mortgage insurance products are generally established based on performance models that consider a broad range of borrower, loan and property characteristics as well as current and projected market and economic conditions. Our premium rates are subject to regulation, and in most states where our insurance subsidiaries are licensed, the formulations by which we derive our premiums must be filed, and in some cases approved, before their use. See “Regulation—State Regulation.”
We have developed our pricing strategy to manage the risk/return profile and maximize the long-term economic value of our insured portfolio by balancing credit risk, profitability and volume considerations in light of the current and projected competitive environment. Consistent with this strategy, our premium rates are based on a broad range of factors including our expectations about competitive and economic conditions and cost of capital, as well as other factors and risk attributes that we consider in developing our assumptions about loan and policy performance.
Premiums on our mortgage insurance products generally are written on either: (i) a recurring basis, which can be monthly or annual premiums, pursuant to our Monthly and Other Recurring Premium Policies or (ii) as a single premium generally paid at the time of loan origination pursuant to our Single Premium Policies. We also offer products where premiums are paid as a combination of an up-front premium at origination, plus a monthly installment. In addition, premiums may include a refundable component. While the majority of our policies terminate when certain criteria, such as prescribed LTV levels, are met, some of our products provide coverage for the life of the loan, subject to certain conditions. There are many factors that influence the types of premiums we receive, including, among others: (i) the preference of customers with whom we do business; (ii) the relative premium levels we and our competitors set for the various forms of premiums offered; and (iii) the percentage of mortgage originations derived from new home purchases versus refinancing transactions, as refinances have historically been more likely to be written as Single Premium Policies.
Mortgage insurance premiums can be funded through a number of methods, and while the coverage remains for the benefit of the insured lender or third-party beneficiary, the premiums may be paid by the borrower or by the lender. Borrower-paid Monthly and Other Recurring Premiums are generally paid to us as part of the borrower’s monthly mortgage payment, while borrower-paid premiums under our Single Premium Policies are paid to us at the time of closing on the home purchase.
16

Part I. Item 1. Business
Lender-paid mortgage insurance premiums are paid by the lender and are typically passed through to the borrower in the form of additional origination fees or a higher interest rate on the mortgage note.
The premium rates on a majority of our Monthly and Other Recurring Premium Policies were established as a fixed percentage of the initial loan balance for a set period of time (typically 10 years), after which the premium generally declines to a lower fixed percentage for the remaining life of the policy. The premium rates on the remaining Monthly and Other Recurring Premium Policies within our insured portfolio were established as a fixed percentage of the loan’s amortizing balance over the life of the policy.
Historically, premiums in the mortgage insurance industry were primarily established through filed rate-cards. Beginning on a broad basis in 2019, the mortgage insurance industry began to widely use various pricing methodologies with differing degrees of risk-based granularity. Although these more recent pricing frameworks are based upon the same general risk attributes that historically have been a part of mortgage insurance pricing, they are incorporating into the underlying pricing tools more granular risk-based pricing factors based on multiple loan, borrower and property attributes.
The shift away from a predominantly rate-card based pricing model and the increase in “black box” pricing frameworks throughout the mortgage insurance industry provides a more dynamic pricing capability that allows for more frequent pricing changes that can be implemented quickly and has contributed to a reduction in overall pricing transparency. Further, in addition to the growing proliferation of black box pricing, industry pricing practices in recent years have also included an increased use of customized rate plans for certain customers, pursuant to which rates may be awarded to customers for only a limited period of time. With the increased prevalence of granular, “black box” pricing and the greater uniformity of master policy terms throughout the industry, pricing has become the predominant competitive market factor for private mortgage insurance and an increasing number of customers are making their choice of mortgage insurance providers primarily based on the lowest price available for any particular loan.
Overall, our approach to pricing is customer-centric and flexible; therefore, we offer a spectrum of risk-based pricing solutions for our customers. This approach represents a continuation of our strategy to pursue multiple pricing delivery options that are best suited to a lender’s loan origination process and balanced with our own objectives for managing our volume of NIW and the economic value derived from our mortgage insurance portfolio. See “Item 1A. Risk Factors—Our mortgage insurance business faces intense competition.
GSE Credit Risk Transfer Premiums
Premium rates for credit risk transfer transactions are established through a sealed-bid auction process in which we and other potential insurers/reinsurers provide their desired allocation of the offering(s) at a specified premium rate to the GSE. We evaluate each transaction, and if we choose to participate, we develop our bid based on performance models that consider a broad range of borrower, loan and property characteristics as well as market and forecasted future economic conditions. After completion of the auction process, the GSEs set a uniform premium based on an assessment of the bids received and, based on their desired counterparty exposure, assign allocations to insurers/reinsurers up to their requested bid amounts, if the pricing is at or above their specified premium rate. As noted above, we discontinued our participation in these transactions in 2021, but we could resume our participation in these transactions in the future.
Underwriting
Mortgage loan applications are underwritten to determine whether they are eligible for our mortgage insurance. We perform this function directly or, alternatively, we delegate to our insured lenders the ability to underwrite the mortgage loans based on compliance with our underwriting guidelines.
Delegated Underwriting. Through our delegated underwriting program, we approve insured lenders to underwrite mortgage loan insurance applications based on our mortgage insurance underwriting guidelines. Each lender participating in the delegated underwriting program must be approved by our risk management group. Utilization of our delegated underwriting program enables us to meet lenders’ demands for immediate mortgage insurance coverage and increases the efficiency of the underwriting process. We use quality control sampling and performance monitoring to manage the risks associated with delegated underwriting. Under the terms of the program, we have certain rights to rescind coverage if there has been a deviation from our underwriting guidelines. For a discussion of these limited Rescission rights, see “—Defaults and Claims—Claims Management—Rescissions.” As of December 31, 2021 and 2020, 69% and 67% of our total first-lien IIF had been originated on a delegated basis, respectively.
Non-Delegated Underwriting. Approved insured lenders may submit mortgage loan applications to us so that we may perform the mortgage insurance underwriting. Some customers prefer our non-delegated underwriting program because we assume responsibility for underwriting the mortgage insurance and, subject to the terms of our Master Policies, generally have less ability to rescind coverage if there is an underwriting error. We leverage loan application data and analytics to categorize mortgage insurance applications based on credit risk and underwriting complexity to improve efficiency in our process and to ensure a heightened focus on the higher risk, complex applications. We use quality control sampling, loan performance monitoring and training to manage the risks associated with our non-delegated underwriting program. As of December 31, 2021 and 2020, 26% and 28% of our total first-lien IIF had been originated on a non-delegated basis, respectively.
17

Part I. Item 1. Business
Contract Underwriting. We also provide third-party contract underwriting services to our mortgage insurance customers pursuant to which we underwrite the mortgage loan for compliance with investor guidelines, which if necessary, may be separate from or in addition to underwriting for our mortgage insurance eligibility. Generally, we offer limited indemnification to our contract underwriting customers. To manage the risks associated with contract underwriting, we train our underwriters, require them to complete continuing education and routinely audit performance to monitor the accuracy and consistency of underwriting practices. As of both December 31, 2021 and 2020, 5% of our total first-lien IIF had been underwritten through contract underwriting.
Mortgage Insurance Portfolio Characteristics
Direct Risk in Force
Exposure in our mortgage insurance business is measured by RIF, which for Primary Mortgage Insurance is equal to the unpaid principal balance of the loan multiplied by our insurance coverage percentage. See “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Mortgage Insurance Portfolio—Insurance and Risk in Force” for additional information about the composition of our Primary RIF.
We analyze our mortgage insurance portfolio in a number of ways to identify any concentrations or imbalances in risk dispersion. We believe that, among other factors, the credit performance of our mortgage insurance portfolio is affected significantly by:
general economic conditions (in particular, interest rates, home prices and unemployment);
the age and performance history of the loans insured;
the geographic dispersion and other characteristics of the properties securing the insured loans, such as the primary purpose of the properties, and the condition of local housing markets, including whether the properties are increasing or decreasing in value over time;
the quality of loan underwriting and servicing; and
the number of borrowers and credit characteristics of the borrower(s) and the characteristics of the loans insured, including the amount of the loan compared to the value of the home.
Persistency Rate
The Persistency Rate is the measure that assesses the amount of time that our insurance is remaining in force. The amount of time that our insurance certificates remain in force has a significant impact on our revenues and our results of operations. Because premiums on our Recurring Premium Policies are earned over time, higher Persistency Rates on these policies increase the premiums we receive and generally result in increased profitability and returns. Conversely, assuming all other factors remain constant, higher Persistency Rates on Single Premium business lower the overall returns from our insured portfolio, as the premium revenue for our Single Premium Policies is the same regardless of the actual life of the insurance policy.
The Persistency Rate reflects the impact that certificate cancellations have on our IIF and the future premiums that we expect to earn over time. Provided that all required premiums are paid, coverage for a loan under our Master Policy generally will be cancelled on the first of the following to occur: (i) the loan insured under the certificate is paid in full; (ii) we settle a claim with respect to the certificate; (iii) we act upon the insured’s or its servicer’s instruction to cancel coverage under the certificate, including as may be required by the HPA or pursuant to GSE guidelines; (iv) the term of coverage expires under the premium plan or upon the terms specified in the certificate; or (v) we cancel, rescind or deny coverage under the certificate.
Loan payoff following a refinance will result in cancellation of coverage and, as a result, historically there is a close correlation between interest rates and Persistency Rates, with lower interest rate environments generally increasing refinancings that increase the cancellation rate of our insurance and therefore lower our Persistency Rate. See “Regulation— Federal Regulation—Mortgage Insurance Cancellation” for more information regarding cancellation and termination requirements for borrower-paid private mortgage insurance meeting certain criteria under the HPA. Additionally, in Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations, see “Key Factors Affecting Our Results—Mortgage—IIF and Related Drivers” and “Mortgage Insurance Portfolio—Insurance and Risk in Force” for more information.
Geographic Dispersion
Radian Guaranty is authorized to write mortgage insurance in all 50 states, the District of Columbia and Guam. We have a geographically diversified mortgage insurance portfolio and we proactively monitor the portfolio for concentration risks at both the state level and metropolitan area level known as Core Based Statistical Areas (“CBSAs”). As of December 31, 2021, three states with the highest amounts of RIF accounted for 24.7% of our RIF, with the highest state concentration being 9.3% in California.
18

Part I. Item 1. Business
See “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Mortgage Insurance Portfolio—Insurance and Risk in Force—Geographic Dispersion” for additional information about the geographic dispersion of our direct Primary Mortgage Insurance. Also, in Item 1A. Risk Factors, see “The credit performance of our mortgage insurance portfolio is impacted by macroeconomic conditions and specific events that affect the ability of borrowers to pay their mortgages” and “Climate change and extreme weather events could adversely affect our businesses, results of operations and financial condition.”
Mortgage Loan Characteristics
Factors that contribute significantly to our overall risk diversification and the credit quality of our RIF include, among others, geographic dispersion, as discussed above, as well as our mix of mortgage insurance products, underwriting and our risk management practices. In evaluating the credit quality of our portfolio and developing our pricing and risk management strategies, we consider a number of borrower, loan and property characteristics in assessing our risk of loss, including LTV and FICO score, as well as a number of other loan and property characteristics, including, without limitation, debt-to-income ratio, average loan size, property type, occupancy type, loan purpose and number of borrowers. See “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Mortgage Insurance Portfolio” for additional information about the credit quality and characteristics of our direct Primary Mortgage Insurance.
Defaults and Claims
Defaults
In our Mortgage segment, the default and claim cycle begins with the receipt of a default notice from the loan servicer. We consider a loan to be in default for financial statement and internal tracking purposes upon receipt of notification by servicers that a borrower has missed two monthly payments. Defaults can occur due to a variety of specific events affecting borrowers, including death or illness, divorce or other family problems, unemployment, factors impacting economic conditions (e.g., regional economic disruptions or disaster related events such as epidemics/pandemics, hurricanes, floods, tornados and wildfires) or other events. Regional economic disruptions derived from natural disasters may be exacerbated by climate change and related environmental factors, which could increase the frequency, scope and intensity of such disasters.
The default rate in our mortgage insurance business is subject to seasonality. Historically, our mortgage insurance business experiences a fourth quarter seasonal increase in the number of defaults and a first quarter seasonal decline in the number of defaults and increase in the number of Cures. While historically this has been the case, macroeconomic factors in any given period may influence the default rate in our mortgage insurance business more than seasonality.
Currently, a segment of U.S. residential mortgage loans may be subject to, or eligible for, certain types of relief as a result of the legislative response to COVID-19, including the CARES Act. Upon request by borrowers of federally or GSE-backed mortgage loans who attest to financial hardship related to the pandemic, the CARES Act requires mortgage servicers to provide these borrowers with up to 180 days forbearance on their mortgage payments, which may be extended for an additional 180 days upon request. The permissible forbearance period of 12 months under the CARES Act has been lengthened by various federal agencies and the length of the period varies depending on the agency, type of mortgage at issue and the date when the borrower initially requested the forbearance. The CARES Act does not provide a defined end date for when the 180-day forbearance must initially be offered. It is possible that the ability to request an initial forbearance may cease when the COVID-19 National Emergency ends. COVID-19 was most recently declared a continuing national emergency on February 24, 2021.
As COVID-19 forbearances end, federal law requires servicers to discuss forbearance and loss mitigation options with their borrowers and afford additional protections to borrowers before their loans are referred to foreclosure. Additionally, the CARES Act provided a temporary foreclosure and eviction moratorium for residential mortgagors with certain federally or GSE-backed mortgages. After being extended multiple times, these moratoriums have expired; however, the existence of these moratoriums significantly impacted the claims process in 2020 and 2021 by preventing the procedural steps necessary for a claim under our insurance policies to be filed, as discussed below under “—Claims.” See “Regulation—Federal Regulation—CARES Act.” While the CARES Act and related federally mandated borrower relief has provided critical support to the housing finance system throughout the pandemic, the ultimate performance of loans that remain in forbearance is not yet known. See “Item 1A. Risk Factors—An extension in the period of time that a loan remains in our defaulted loan inventory may increase the severity of claims that we ultimately are required to pay.”
Claims
Defaulted loans that fail to become current, or “cure,” may result in a claim under our mortgage insurance policies. Mortgage insurance claim volume is determined by the circumstances surrounding the default. The rate at which defaults cure, or do not go to claim, depends in large part on a borrower’s financial resources and circumstances (including whether the borrower is eligible for a loan modification), local housing prices (i.e., whether borrowers are able to cure defaults by selling the property in full satisfaction of all amounts due under the mortgage), interest rates, unemployment, inflationary pressures and other factors impacting economic conditions.
19

Part I. Item 1. Business
In our first-lien Primary Mortgage Insurance business, in order to submit a claim, the insured must first either acquire title to the property (typically through a foreclosure proceeding) or we must approve a third-party sale of the property. The time for a lender to acquire title to a property through foreclosure varies depending on the state, and in particular whether a state requires a lender to proceed through the judicial system to complete the foreclosure. Claim activity is not spread evenly throughout the coverage period of a book of business. Historically, except for periods of economic distress, we have experienced relatively few claims during the first two years following issuance of a policy.
In recent years, the average time for us to receive a claim has increased as a result of COVID-19-related relief programs discussed above. For example, payment and foreclosure forbearance programs instituted at the federal and state levels in response to the COVID pandemic have caused defaulted loans to remain in our defaulted loan inventory for a protracted period of time. See “Item 1A. Risk Factors—An extension in the period of time that a loan remains in our defaulted loan inventory may increase the severity of claims that we ultimately are required to pay.”
For Pool Mortgage Insurance, which represents less than 1% of our RIF at December 31, 2021, our policies typically require the insured to not only acquire title but also to actively market and ultimately liquidate the real estate asset before filing a claim, which generally lengthens the time between a default and a claim submission.
In addition to claim volume, Claim Severity is another significant factor affecting losses. We calculate the Claim Severity by dividing the claim paid amount by the original coverage amount. Factors that impact the severity of a claim include, but are not limited to, the size of the loan, the amount of mortgage insurance coverage placed on the loan, the amount of time between default and claim during which we are expected to cover certain interest (capped at two years under our Prior Master Policy and capped at three years under our 2014 and 2020 Master Policies) and expenses, and the impact of our Loss Mitigation and other loss management activities with respect to the loan.
Home price appreciation as well as pre-foreclosure sales, acquisitions and other early workout efforts help to reduce overall Claim Severity, as do actions we may take to reduce a claim payment due to servicer negligence, as discussed below in “—Claims Management.” See “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Results of Operations—Mortgage—Year Ended December 31, 2021 Compared to Year Ended December 31, 2020—Provision for Losses.”

Our claims management process is focused on analyzing and processing claims to ensure that we pay valid claims in accordance with our policies. Our mortgage insurance claims management department pursues opportunities to mitigate losses both before and after claims are received.
In our mortgage insurance business, upon receipt of a valid claim, we have a range of settlement options for calculating the claim amount (also referred to as calculated loss), as set forth in our Master Policies. Most frequently, we settle a valid claim with the “Percentage Option” by paying the maximum liability and allowing the insured lender to keep title to the property. For this purpose, the maximum liability is determined by multiplying (x) the claim amount (which consists of the unpaid loan principal, plus past due interest for a period of time specified in our Master Policies, plus certain expenses associated with the default, and minus certain deductions) by (y) the applicable coverage percentage. We also have the following alternative settlement options:
(i)Approved Sale Option: Subject to any reduction provided for elsewhere in our policy, we may pay the claim amount (not to exceed the lender’s entire loss or our maximum liability under the Percentage Option) by taking into account the net proceeds received by the lender following an approved sale such as a “short sale” or “deed-in-lieu” transaction;
(ii)Acquisition Option: Subject to any reduction provided for elsewhere in our policy, we may pay the entire claim amount (as described above but without application of the coverage percentage) upon the conveyance to us of good and marketable title to the property; or
(iii)Anticipated Loss Option: In certain circumstances, as outlined in our Master Policies, the settlement is primarily based on the claim amount minus the net proceeds we reasonably anticipate would be generated if the property, in its original condition on the effective insurance commitment date, reasonable wear and tear excepted, were sold to a third party for fair market value.
Approved sales in which the underlying property has been sold for less than the outstanding loan amount are commonly referred to as “short sales.” Although short sales may have the effect of reducing our ultimate claim obligation, in many cases, a short sale will result in the payment of a claim in an amount that is equal to the maximum liability amount under the Percentage Option.
Under our Master Policies, we retain the right to consent prior to consummation of any short sale. We have entered into agreements with each of the GSEs pursuant to which we delegate to the GSEs our prior consent rights with respect to short sales on loans owned by the GSEs, as long as the short sales meet applicable GSE guidelines and processes for short sales and subject to certain other factors set forth in these agreements.
20

Part I. Item 1. Business
We also provide for limited delegation authority to certain loan servicers for short sales under specific circumstances. For loans that are not owned by the GSEs and for which we have not granted specific delegation authority to the loan servicer, we perform an individual analysis of each proposed short sale and provide our consent to these sales when appropriate. Historically, we have consented to a short sale only after reviewing various factors, including among other items, the sale price relative to market and the ability of the borrower to contribute to any shortfall in the sale proceeds as compared to the outstanding loan amount.
After a claim is received, our loss management specialists may focus on:
a review to determine compliance with applicable loan origination programs and our mortgage insurance policy requirements, including: (i) whether the loan qualified for insurance at the time the certificate of coverage was issued; (ii) whether the insured has satisfied its obligation in meeting all necessary conditions in order for us to pay a claim, including submitting all necessary documentation in connection with the claim (commonly referred to as “claim perfection”); and (iii) whether the loan was appropriately serviced in accordance with the standards set forth in our Master Policies;
analysis and prompt processing to ensure that valid claims are paid in an accurate and timely manner;
responses to loss mitigation opportunities presented by the insured; and
management and disposal of acquired real estate.
Radian Guaranty has entered into a Factored Claim Administration Agreement with Fannie Mae that applies to certain loans owned by Fannie Mae that were insured under our Master Policies for which a claim is submitted on or after October 1, 2018. Pursuant to the agreement, for the loans subject to the agreement, Radian Guaranty will determine the amount of covered expenses forming part of a loss (other than unpaid principal balance and delinquent interest) using prenegotiated expense factors. The expense factors are based on certain characteristics of each covered loan, including the unpaid principal balance at the time of default, property type and location, and property disposition.
Claim Denials
We have the legal right under our Master Policies to deny a claim under certain conditions, such as when the loan servicer does not produce documents necessary to perfect a claim (e.g., evidence that the insured has acquired title to the property) within the time period specified in our Master Policies. Most often, a Claim Denial is the result of a servicer’s failure to provide the loan origination file or other critical servicing documents for review.
If, after requests by us, the loan origination file or other servicing documents are not provided to us, we generally deny the claim. If we deny a claim, we may continue to allow the insured the ability to perfect the claim for a limited period of time, as specified in our Master Policies. If the insured successfully perfects the claim on a timely basis, we will process the claim, including, as appropriate, by conducting a review of the loan file to ensure that underwriting and loan servicing were conducted properly.
If, after completion of this process, we determine that the claim was not perfected, other conditions precedent to coverage have not been met, or any exclusions apply, the insurance claim is denied and we consider the Claim Denial to be final and resolved. Although we may make a final determination with respect to a Claim Denial, it is possible that after we have denied coverage a legal challenge to our decision may be brought within a period of time specified under the terms of our Master Policies.
Rescissions
Mortgage insurance master policies generally protect mortgage insurers from the risk of material misrepresentations and fraud in the origination of an insured loan by establishing the right, under certain conditions, to unilaterally rescind coverage. Under the terms of our Master Policies, typical events that may give rise to our right to rescind coverage include: (i) we insured a loan in reliance upon an application for insurance that contains a material misstatement, misrepresentation or omission, whether intentional or otherwise, or that was issued as a result of an act of fraud or (ii) we find that there was negligence in the origination of a loan that we insured. We also have rights of Rescission arising from a breach of the insured’s representations and warranties that are contained in our Master Policies or endorsements thereto and are required with our delegated underwriting program.
If we rescind coverage based on a determination that a loan did not qualify for insurance, we provide the insured with a period of time to challenge, or rebut, our decision. If a rebuttal to our Rescission is received and the insured provides additional information supporting the continuation (i.e., non-rescission) of coverage, we have the claim re-examined internally by a separate, independent investigator. If the additional information supports the continuation of coverage, the insurance is reinstated and if there is a claim, it proceeds to the next step in our claims review process. Otherwise, if we determine that the loan did not qualify for coverage, the insurance certificate is rescinded (and we issue a premium refund under the terms of our Master Policies), and we consider the Rescission to be final and resolved. Although we may make a final determination internally with respect to a Rescission, it is possible that a legal challenge to our decision to rescind coverage may be brought after we have rescinded coverage during a period of time that is specified under the terms of our Master Policies.
21

Part I. Item 1. Business
Following the financial crisis, the FHFA and the GSEs identified minimum standards and specific requirements for private mortgage insurer master policies, including rescission relief principles that limit the right to rescind coverage when certain conditions are met. These rescission relief principles have limited the potential for Loss Mitigation Activity throughout the private mortgage insurance industry.
In accordance with these rescission relief principles, we have incorporated provisions into our 2014 Master Policy and 2020 Master Policy that generally provide rescission relief based on the number of months that borrowers remain current on their mortgage loans. As a consequence, our rights to conduct Loss Mitigation Activity involving rescission as a remedy generally are more limited under these more recent Master Policies as compared to our Prior Master Policy, but our more recent Master Policies continue to include certain life-of-loan reservation of rescission rights specified in the Master Policy, including fraud and certain patterns of fraud. See “Item 1A. Risk Factors—Changes in the charters, business practices or role of the GSEs in the U.S. housing market generally, could significantly impact our businesses.”
Claim Curtailments
We depend on third-party servicing of the loans that we insure. Servicers are responsible for being the primary contact with borrowers regarding their loans, and we generally do not have first-party contact with borrowers. Dependable loan servicing is necessary for, among other things, timely billing and premium payments to us and effective loss mitigation opportunities for delinquent or near-delinquent loans. As such, proper loan servicing is critical to the performance of our insured mortgage portfolio, especially when borrowers experience difficulty paying their mortgages.
Our Master Policies require servicers to service our insured loans in a reasonable, prudent manner consistent with the highest standards of servicing in use in the residential mortgage industry, and we have rights under our Master Policies to curtail, and in some circumstances, deny claims due to servicer negligence. Examples of servicer negligence may include, without limitation:
a failure to report information to us on a timely basis as required under our Master Policies;
a failure to pursue loss mitigation opportunities presented by borrowers, realtors and/or any other interested parties;
a failure to pursue loan modifications and/or refinancings through programs available to borrowers or an undue delay in presenting claims to us (including as a result of improper handling of foreclosure proceedings), which increases the interest or other components of a claim we are required to pay; and
a failure to initiate and diligently pursue foreclosure or other appropriate proceedings within the timeframe specified in our Master Policies.
Although we could seek post-claim recoveries from the beneficiaries of our policies if we later determine that a claim was not valid, because our loss mitigation process is designed to ensure compliance with our policies prior to payment of a claim, historically we have not sought recoveries from the beneficiaries of our mortgage insurance policies once a claim payment has been made.
From time to time, claims management may result in disputes with our customers that ultimately produce litigation or other legal proceedings. See Note 13 of Notes to Consolidated Financial Statements.
homegenius
homegenius Business Overview
A key element of our overall business strategy is to use our homegenius segment to diversify our business and revenue streams by increasing our participation in multiple facets of the residential real estate and mortgage finance markets. Our homegenius businesses are comprised of title, real estate and technology products and services. Through this business segment, we offer an array of products and services to market participants across the real estate value chain, including consumers, mortgage lenders, mortgage and real estate investors, GSEs and real estate brokers and agents. We believe that the combination of our mortgage insurance business with our unique set of diversified homegenius products and services provides us with an opportunity to become more relevant to our customers and is a competitive differentiator for us compared to other private mortgage insurance companies.
The macroeconomic conditions and other events that impact the housing, mortgage finance and related real estate markets affect the demand for the products and services we offer through our homegenius business. Sales volume in our homegenius business varies based on the overall activity in the housing and mortgage finance markets and the health of related industries. See “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Key Factors Affecting Our Results—homegenius” for additional information.

Part I. Item 1. Business
Services Offered
Title Services
We provide a comprehensive suite of insurance and non-insurance title, closing and settlement services for purchase, refinance and home equity transactions to mortgage lenders, mortgage investors and GSEs as well as directly to consumers for residential mortgage loans.
Title insurance is a contract of indemnity for losses stemming from a covered defect in title to real property, such as adverse ownership interests, liens, or other encumbrances, that predates the policy and is not otherwise excluded or excepted from coverage. Our title policies are issued following a determination of insurability, which is based on a title search that may include review of the public land records, court filings, maps, surveys, previously issued title policies, and any other documentation that may contain information concerning interests in real property.
There are two types of title insurance policies. Lenders’ policies insure the validity and priority of the insured mortgage and typically provide coverage up to the outstanding mortgage loan balance, until the loan is paid off. Owners’ policies are issued directly to the real estate purchaser and provide coverage to the owner in an amount equal to the purchase price of the property. Both types of policies are issued for a one-time premium paid at closing of the home purchase. Premium amounts vary across jurisdictions and also depend on the amount of coverage given and the type of policy being issued.
Losses on policies occur in the form of claims payouts and/or the cost of defending or establishing title. Title claims may arise from a number of factors, such as title search and examination errors, fraud, forgery, incorrect legal descriptions, and failure to pay off existing liens. Title insurers are also responsible for the cost of defending the insured in litigation alleging covered title defects, regardless of the merits of the allegations.
In addition to title insurance, we offer a full complement of title services that include tax reports; recording services; document retrieval; default title services; deed reports and property reports. Our closing and settlement services include electronic execution of some or all mortgage loan closing documents (eClosing), as well as traditional signing services.
Real Estate Services
We provide real estate services, including real estate asset management and real estate valuation services, to our customers. Our asset management solutions help real estate investors and lenders improve execution on their real estate properties. Through these asset management services, we manage properties owned primarily by financial institutions and mortgage investors by overseeing the REO disposition process. We conduct this work primarily by engaging third-party independent contractors to perform the eviction and redemption process, as well as property preservation and repairs on behalf of our customers. In addition, we offer a web-based asset management workflow solution to assist in managing REO assets, rental properties, due diligence for bulk acquisitions of multiple properties, loss mitigation efforts and short sales.
We also offer a full range of services that serve the single-family rental asset class. This asset class primarily involves the securitization of a single loan backed by multiple rental properties owned primarily by large institutional investors. Our comprehensive single family rental services provide a centralized, single point of contact for facilitating the property valuation and diligence services needed to support single family rental warehouse lending and securitization activity. Our warehouse lending valuation and diligence reviews also serve institutional iBuyers, who use technology to value, purchase and thereafter securitize, rent or sell homes.
Through our licensed real estate broker subsidiary, Red Bell, we also provide a suite of real estate valuation products and services to lenders, servicers, investors and GSEs, including broker price opinions (i.e., price estimates provided by real estate brokers familiar with the particular market) and various valuations that utilize technology, including hybrid appraisals (where licensed appraisers complement their efforts by accessing technology enabled valuation services), automated valuation services (enabling a qualified user to obtain an estimated value based on a technology driven analysis of data and information about comparable transactions) and interactive valuation services (where a qualified user can utilize their knowledge and preferences as inputs to technology tools to obtain a valuation estimate).
Technology Services
In addition to the services described above, we are developing a growing suite of real estate technology products and services that are designed to facilitate real estate transactions and are provided as proprietary SaaS solutions.
These digital services and solutions, which will be offered primarily through our licensed real estate broker subsidiary, Red Bell, include:
geneuity, a SaaS smart workflow system that integrates features such as task management, pipeline tracking, contacts, document storage, e-signature and communication into a single platform enabling real estate brokers and agents to manage real estate transactions more efficiently;
geniusprice technology, a SaaS property intelligence platform that combines predictive modeling, artificial intelligence, automation and imaging review capabilities with a real estate broker’s access to local data to create price estimates and property condition reports; and
23

homegenius connect, a service that helps match interested homebuyers with local real estate agents.
Revenue Drivers
Our homegenius segment is dependent upon overall activity in the mortgage, real estate and mortgage finance markets, as well as the overall health of the related industries. Due, in part, to the transactional nature of the business, revenues for our homegenius segment are subject to fluctuations from period to period, including seasonal fluctuations that reflect the activities in these markets. Sales volume is also affected by the number of competing companies and alternative products offered in the market.
We earn net premiums on title insurance written by Radian Title Insurance. For our other homegenius offerings, we primarily use fixed-price contracts, pursuant to which we agree to perform the specified services and deliverables for a pre-determined per-unit price. To a lesser extent, for a portion of our REO management services and our real estate brokerage services, we utilize percentage-of-sale contracts, under which we are paid a contractual percentage of the sale proceeds upon the sale of each property.
In most cases, our contracts with our clients do not include minimum volume commitments and can be terminated at any time by our clients. Although some of our contracts and assignments are recurring in nature, and include repetitive monthly assignments, a significant portion of our current homegenius revenues are transactional in nature and may be performed in connection with securitizations, real estate purchases and sales or other transactions.
We expect our revenue from our technology products and services to grow in future periods, which would result in a higher percentage of total revenues being recurring in nature. Due to the transactional nature of our current business, our homegenius segment revenues may fluctuate from period to period as transactions are commenced or completed. In addition, our segment revenues are impacted by the volume of real estate transactions in the marketplace, which may fluctuate from period to period. See “Item 1A. Risk Factors—We face risks associated with our homegenius business.”
For additional information on the most significant factors affecting our homegenius business, see “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Key Factors Affecting Our Results—homegenius.”

Competition
Mortgage
We operate in the highly competitive U.S. mortgage insurance industry. Our competitors primarily include other private mortgage insurers and federal and state governmental agencies, principally the FHA and VA.
Including us, there are currently six active participants in the private mortgage industry that are approved and eligible to write business for the GSEs. The other participants are:
Arch Capital Group Ltd. (includes both Arch Mortgage Insurance Company and United Guaranty Residential Insurance Company);
Enact Holdings, Inc. (formerly Genworth Mortgage Holdings, Inc.);
Essent Group Ltd.;
MGIC Investment Corporation; and
NMI Holdings, Inc.
24

Part I. Item 1. Business
We compete directly with other private mortgage insurers primarily on the basis of price, underwriting guidelines, overall service, customer relationships, perceived financial strength (including comparative credit ratings) and reputation. Overall customer service competition in our mortgage insurance business is based on, among other things, effective and timely delivery of products, timeliness of claims payments, customer service, timely and accurate administration of policies, training, loss mitigation efforts and management and field service expertise.
For Radian, customer service also includes our ability to offer products and services through our homegenius business that are relevant to our mortgage insurance customers and complement our mortgage insurance products.
Pricing has always been competitive in the mortgage insurance industry, but as discussed above under “Mortgage—Pricing,” with the increased prevalence of granular, “black box” pricing and custom rate cards throughout the industry and the greater uniformity of master policy terms throughout the industry, pricing has become the predominant competitive market factor for private mortgage insurance. We monitor various competitive and economic factors while seeking to enhance the long-term value of our portfolio by balancing credit risk, profitability, and volume and capital considerations in developing our pricing strategies.
We take a disciplined approach to establishing our premium rates and seek to write a mix of business that we expect to produce our desired level of NIW while managing the risk/return profile and maximizing the long-term economic value of our insured mortgage portfolio, taking into consideration the competitive environment. See “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Key Factors Affecting Our Results—Mortgage—Premiums.” Based on publicly available information, we estimate that our share of NIW within the private mortgage insurance market was approximately 16% for 2021.
Certain of our private mortgage insurance competitors currently have better financial strength ratings than we have and/or are subsidiaries of larger corporations, which may give them a competitive advantage.
Private mortgage insurance competes for a share of the insurable mortgage market with the single-family mortgage insurance programs of the FHA and VA. Private mortgage insurance execution competes with the programs offered by the FHA on the basis of loan limits, pricing, credit guidelines, terms of our insurance policies and loss mitigation practices.
Since the 2007-2008 financial crisis, the private mortgage insurance industry has improved its share of the insurable, low down payment market, primarily due to: (i) improvements in the financial strength of private mortgage insurers; (ii) the development of new products, pricing delivery tools and marketing efforts directed at competing with FHA programs and execution; (iii) increases in the FHA’s pricing; (iv) the U.S. government’s pursuit of legal remedies against FHA-approved lenders related to loans insured by the FHA; and (v) various policy changes at the FHA, including the general elimination of the premium cancellation provision that exists for borrower-paid private mortgage insurance.
We believe that better execution for borrowers with higher FICO scores, lender preference and the inability to cancel FHA insurance for certain loans have provided a competitive advantage for private mortgage insurers. The FHA’s share of the total insured mortgage market (which includes FHA, VA and private mortgage insurers) was reported to be 25% in 2021, compared to 24% in 2020. See “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Key Factors Affecting Our Results—Mortgage—NIW and Related Drivers.
If the competitive position of the FHA is enhanced, it could have a negative effect on our ability to compete with the FHA. See “Regulation—Federal Regulation—Housing Finance Reform and the GSEs’ Business Practices” for a discussion of several recent developments that could enhance the FHA’s competitive position relative to private mortgage insurance.
We also have faced increasing competition from the VA. Based on publicly available information, the VA’s share of the total insured mortgage market was 31% in 2021, compared to 32% in 2020. We believe that the VA remains a strong participant in the overall market because the VA offers 100% LTV loans and charges a one-time funding fee that can be included in the loan amount with no separate monthly expense, and because of an increase in the number of borrowers that are eligible for the VA’s program.
In addition, as market conditions change, alternatives to traditional private mortgage insurance may become more prevalent, which could reduce the demand for private mortgage insurance. These alternatives have included structures commonly referred to as “investor paid mortgage insurance” in which affiliates of traditional mortgage insurers that are not subject to the PMIERs directly insure the GSEs against loss. For additional information about these structures, see “Regulation—Federal Regulation—Housing Finance Reform and the GSEs’ Business Practices.”
It is difficult to predict what other types of credit risk transfer transactions and structures or other forms of credit enhancement, including GSE-sponsored alternatives to traditional mortgage insurance, might be used in the future. If any of these alternatives were to displace standard primary loan level private mortgage insurance, the amount of insurance we write may be reduced and our future prospects could be negatively impacted.
See “Item 1A. Risk Factors—Our mortgage insurance business faces intense competition.”
25

Part I. Item 1. Business
homegenius
We believe our homegenius business is uniquely positioned as a provider of an array of products and services to participants across the real estate value chain. While we are not aware of any other single company that provides a comparable range of services to the residential mortgage and real estate industries, our homegenius business has multiple strong competitors within each of its individual lines of business.
Significant competitors for our homegenius business include:
Title Services – Blend Labs, Inc.; Fidelity National Title Insurance Company; First American Financial Corporation; First National Title Insurance Company; Mortgage Connect, LP; National Title Insurance Company; North American Title Insurance Company; Old Republic Title Insurance Group, Inc.; OS National LLC; Selene Title LLC; ServiceLink IP Holding Company, LLC; Spruce Title Company; Stewart Title Guaranty Company; Summit Title Services, LLC; Westcor Land Title Insurance Company; and WFG National Title Insurance Company.
Real Estate Services – Black Knight, Inc.; ClearCapital.com, Inc.; CoreLogic, Inc.; Covius Holdings, Inc.; Equator, an Altisource Business Unit; First American Financial Corporation; First American Mortgage Solutions, LLC.; HouseCanary, Inc.; Keystone Asset Management; Pro Teck Valuation Intelligence; Res.Net; ServiceLink IP Holding Company, LLC; SingleSource Property Solutions, LLC (Resolute Diligence Solutions); VRM Mortgage Services; and Xome Inc.
In addition, we believe that our technology services and products currently under development will compete with offerings from various real estate SaaS companies. Across all business lines in our homegenius segment, we compete on the basis of industry expertise, price, technology, data access, service levels and relationships.
Customers
Mortgage
The principal customers of our mortgage insurance business are mortgage originators such as mortgage banks, commercial banks, savings institutions, credit unions and community banks.
We actively monitor our customer concentration and regularly engage in efforts to diversify our customer base. Our largest single mortgage insurance customer (including branches and affiliates) measured by NIW, accounted for 13.9% of NIW during 2021, compared to 13.3% and 7.2% in 2020 and 2019, respectively. The percentage of NIW generated by our top 10 customers was 38.3% in 2021. No single customer contributed earned premiums that accounted for more than 10% of our consolidated revenues in 2021, 2020 or 2019. See “Item 1A. Risk Factors—Our NIW and franchise value could decline if we lose business from significant customers.”
homegenius
We have a broad range of customers in our homegenius segment, including many of our Mortgage customers, due to the products and services we offer across the mortgage and real estate value chain. Our principal customers (non-affiliated) are:
Mortgage originators such as mortgage banks, commercial banks, savings institutions, credit unions and community banks;
Aggregators, issuers and investors in RMBS, whole loans and other mortgage-related debt instruments, including the GSEs, private equity, hedge funds, real estate investment trusts and investment banks;
Single family rental warehouse lenders, owner/operators, builders, capital markets institutional investors and securitization issuers;
Mortgage servicers;
Real estate brokers and agents; and
Consumers.
Our customers include many of the largest financial institutions and participants in the mortgage sector and, as such, our services revenue is concentrated among our largest customers. For the year ended December 31, 2021, the top 10 homegenius customers generated approximately 57.9% of the homegenius segment’s services revenue.
Sales and Marketing
Our sales and marketing efforts are focused on establishing, building and maintaining valuable customer relationships. Given the range of solutions we offer across mortgage and real estate, we believe we have significant opportunity to expand our sales to our existing customer base as well as to new customers. We have a core team of account managers who sell all
26

Part I. Item 1. Business
products and solutions across our businesses, as well as sales teams with subject matter expertise in particular services and the related needs of the customers we serve.
Marketing and communications activities include direct marketing; print and digital advertising; digital marketing including email, web, content and social media; public relations and thought leadership; brand strategy and expression; event marketing including customer meetings, conferences and trade shows and other targeted initiatives designed to generate new sales opportunities, drive customer adoption of our services and retain our existing customers. We continue to adapt our sales and marketing efforts based on the current environment to offer tools and techniques to connect virtually and engage with current and potential customers.
All sales and marketing efforts are supported by functional areas that provide additional touch points for our customers. For example, our Inside Sales Team is responsible for managing and growing customer relationships and promoting increased customer adoption and our Client Success, Customer Service and Training Teams provide customized service as well as educational sessions to our customers.
We expect that our approach to selling our products across our mortgage and real estate services businesses will strengthen our relationships with customers, attract new customers and enhance our ability to compete.
Investment Policy and Portfolio
Our investment portfolio is our primary source of claims paying resources and also contributes to our earnings. We seek to manage our investment portfolio within our targeted risk and return tolerances based on our current liability projections and business and economic outlook to maintain sufficient liquidity levels to satisfy our current and future operating requirements and other financial needs.
Our investment strategy uses an asset allocation methodology that takes into consideration regulatory constraints, our business environment and consolidated risks as well as current investment conditions. With respect to our fixed income investments, the following internal investment policy guidelines, among others, are applied at the time of investment and continually monitored.
Internal investment policy guidelines
NAIC DesignationRatings EquivalentInternal Policy
1“A-” and aboveAt least 75% of the portfolio Fair Value
2“BBB+” to “BBB-”Not more than 25% of portfolio Fair Value
3 to 6“BB+” and belowNot more than 10% of portfolio Fair Value
Our portfolio has been constructed to maximize long-term expected returns while maintaining an acceptable risk level. Our investment objectives are to utilize appropriate risk management oversight to optimize after-tax returns, while preserving capital. We calibrate the level of our short-term investments based on our overall investment portfolio duration, risk appetite and expected short-term cash requirements.
Our investment policies and strategies are subject to change, depending on regulatory, economic and market conditions and our then-existing or anticipated financial condition and operating requirements, including our current and future tax positions. The investments held at our insurance subsidiaries are also subject to insurance regulatory requirements applicable to such insurance subsidiaries.
Oversight responsibility of our investment portfolio rests with management, and allocations are set by periodic asset allocation studies, calibrated by risk and after-tax return considerations. The risks we consider include, among others, duration, convexity, liquidity, market, sector, structural, interest rate and credit risks. As of December 31, 2021, we internally managed 8.0% of the investment portfolio (the portion of the portfolio largely consisting of U.S. Treasury securities, money market funds, equities and certain exchange-traded funds), with the remainder primarily managed by three external managers. External managers are selected by management based primarily upon their ability to meet our investment goals and objectives, based upon factors such as historical returns and the stability of their management teams. Management’s selections of external managers are presented to, approved and monitored by the Finance and Investment Committee of our board of directors.
At December 31, 2021, our investment portfolio had a cost basis of $6.3 billion and a carrying value of $6.6 billion. At December 31, 2021, 95.5% of our investment portfolio was rated investment grade. The weighted-average duration of the assets in our investment portfolio as of December 31, 2021 was 4.5 years. For additional information about our investment portfolio, see “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources—Investment Portfolio, as well as Notes 5 and 6 of Notes to Consolidated Financial Statements.

Part I. Item 1. Business
Enterprise Risk Management
Risk Philosophy, Vision and Appetite
As a financial services organization, risk management is a critical part of our business. The following goals guide our strategy and actions as a risk management organization:
Embed and continually reinforce a disciplined, corporate-wide risk culture that utilizes an understanding of risk/return trade-offs to drive quality decisions and achieve long-term, through-the-cycle profitability;
Maintain credit, underwriting, pricing and risk/return disciplines based on sound data and analytics and continuous feedback throughout the organization;
Proactively monitor business, counterparty, economic, housing and regulatory trends to identify and mitigate emerging risks;
Continually refine analytical and technological capabilities, processes and systems to effectively identify, assess and manage risks; and
Develop and leverage tools and capabilities to inform and optimize capital allocation within our risk appetite in support of our corporate strategy.
Risk Categories
Our risk appetite, or the amount of risk we are willing to take on in pursuit of value, is driven by our business strategy, which is established by executive management and overseen by our board of directors. We define our risk appetite qualitatively through the following key risk categories where strategic execution occurs: credit; financial; strategic; operational and regulatory and compliance. We do not treat reputational risk as a distinct category of risk; rather, we view reputational risk as pervasive throughout our entire risk portfolio, as each risk on its own can impact our reputation if not mitigated or managed properly.
Risk Governance
Board of Directors
Our board of directors is responsible for the general oversight of risks. Our board of directors seeks to understand and oversee the most critical risks relating to our business, allocates responsibilities for the oversight of risks among the full board and its committees, and reviews the systems and processes that management has in place to manage current risks, as well as those that could arise in the future.
The board regularly meets with management to receive reports derived from: (i) our ERM function regarding the most significant risks we are facing, and the steps being taken to assess, manage and mitigate those risks; (ii) our information security function regarding cybersecurity risks and our efforts to mitigate such risks; and (iii) our compliance programs and our efforts to embed a culture of compliance throughout the organization to encourage ethical behavior and mitigate risks of regulatory non-compliance. The full board further considers current and potential future strategic risks as part of its annual strategic planning session with management.
Executive Management
Our senior executive management team regularly monitors and discusses risks related to our businesses through various management committees. Our Pricing and Risk Committee, Capital and Liquidity Review Committee and Model Governance Committee (these committees collectively comprise our Asset Liability Committee) focus on identifying risks and decision-making related to pricing, credit, capital, liquidity and model management, including risk/return analysis associated with different business opportunities. Other management committees focused on risk management include, but are not limited to, our ERM Council, Executive Information Security Committee, Regulatory Compliance Council and Enterprise Information Governance Committee.
Integrated ERM Framework
We have adopted an integrated approach to risk management, which includes, among other things: (i) a centralized ERM function that resides within the office of our General Counsel and is responsible for overseeing the process for risk identification, assessment, management and mitigation across the organization and (ii) an internal audit function that performs periodic, independent reviews and tests compliance with risk management policies, procedures and standards across the Company.
Our ERM framework is designed to provide executive management with the ability to identify and evaluate the most significant risks we face and to calibrate risk mitigation strategies to account for challenges in the current business environment, as well as external factors that may negatively impact our operations. In practice, our ERM function represents a cross-functional and enterprise-wide effort, consisting of subject matter experts and experienced managers, that utilizes a
28

Part I. Item 1. Business
systematic method to identify, evaluate and monitor both known and emerging risks. Risk assessments and mitigation plans are developed to address these risks. Risk scoring and validation of the effectiveness of risk management plans through management reporting facilitate program sustainability and promote accountability for risk management activities throughout the Company.
As part of our ERM program, our mortgage insurance and title insurance businesses employ comprehensive risk management functions, which, in conjunction with the oversight of the Risk Committee of our board of directors, are responsible for monitoring compliance with our risk-related policies, managing our insured portfolios and communicating credit related issues to management, our board of directors and our customers.
Mortgage Insurance Risk Management
Risk Origination and Servicing. We believe that understanding our business partners and customers is a key component of managing risk. Accordingly, we have a Counterparty Risk Management team that leverages our Customer and Servicer Segmentation Framework so that we can more effectively perform ongoing monitoring of loan performance, underwriting quality and the risk profile and mix of business of a customer’s mortgage insurance applications. The Counterparty Risk Management team monitors trends at the customer level, identifies customers who may exceed certain risk tolerances and shares meaningful performance data with our customers to help them improve. The team is also responsible for lender corrective action in the event we discover credit performance issues, such as high early payment default levels.
Portfolio Management. We have developed risk and capital allocation models to support our mortgage insurance business. These models provide comprehensive analytics that help us establish portfolio limits for product type, loan attributes, geographic concentrations and counterparties. We proactively monitor market concentrations across these and other attributes. We also identify, evaluate and negotiate potential transactions for terminating insurance risk and for distributing risk to third parties, including through reinsurance arrangements. See “—Risk Distribution below for more information about the use of reinsurance as a risk management tool in our mortgage insurance business. As part of our portfolio management function, we monitor and analyze the performance of various risks in our mortgage insurance portfolio. We use this information to develop our mortgage credit risk and counterparty risk policies, and as a component of our default and prepayment analytics.
Credit Policy. We maintain mortgage-related credit risk policies that reflect our tolerance levels regarding counterparty, portfolio and operational risks involving mortgage collateral. Based on our policies and risk tolerances, our credit policy function develops and updates our mortgage insurance eligibility requirements and guidelines through regular monitoring of competitor offerings, customer input regarding lending needs, analysis of historical performance and portfolio trends, quality assurance results and underwriter experience and observations. The credit policy function works closely with our mortgage insurance underwriters to ensure that underwriting decisions align with risk tolerances and principles.
Quality Assurance. Our Quality Assurance function supports our credit analytics function by auditing individual loan files to examine underwriting decisions for compliance with agreed-upon underwriting guidelines. These audits are conducted across loans submitted through our delegated and non-delegated underwriting channels. Our quality assurance team also audits our customers and our underwriters to monitor quality in our NIW.
Loss Mitigation. We have a dedicated loss mitigation group that works with servicers to identify and pursue loss mitigation opportunities for loans in both our performing and non-performing (defaulted) portfolios. This includes regular surveillance and benchmarking of servicer performance with respect to default reporting, borrower retention efforts, foreclosure alternatives and foreclosure processing. Through this process, we seek to hold servicers accountable for their performance and communicate to servicers identified best practices for servicer performance. See “Mortgage—Defaults and Claims—Claims Management” above for more information.
Risk Modeling. Our risk modeling team uses analytical techniques to develop and maintain economic scenario generation models and loan level default and prepayment models for a wide range of risk management applications, including portfolio analysis, credit decision making, forecasting and loss reserving.
Risk Distribution. In our mortgage insurance business, we use reinsurance as a capital and risk management tool to lower the risk profile and financial volatility of our mortgage insurance portfolio through economic cycles. We have distributed risk through third-party quota share and excess-of-loss reinsurance arrangements, including through the capital markets using mortgage insurance-linked notes transactions. In recent years, we have expanded our risk distribution strategy in an effort to optimize the amounts and types of capital and risk distribution deployed against insured risk. The objectives of our risk distribution strategy include: (i) supporting our overall capital plan by reducing our cost of capital, increasing capital efficiency and enhancing our projected returns on capital and (ii) reducing portfolio risk and financial volatility through economic cycles. For additional information regarding our reinsurance programs, see Note 8 of Notes to Consolidated Financial Statements.
Title Insurance Risk Management
We take a prudent approach to assessing and managing risk in our title insurance business through the use of well-trained underwriters, stringent underwriting guidelines and the imposition of per file risk limits and third-party reinsurance on a per policy basis, over certain policy limits.
29

Part I. Item 1. Business
Underwriting and Quality Assurance. Our agents, underwriters and title examiners receive training and feedback in the examining and underwriting of residential and commercial title insurance for both refinance and purchase transactions. Specific title commitments are selected for further review to ensure that underwriting decisions comply with agreed-upon underwriting guidelines and that the policies are within single risk limits.
Credit Policy. We have developed and maintain policies for our title insurance business, which reflect our risk tolerance levels. Risk limits are imposed on selected loan types and reinsurance is currently required on all policies with loan amounts above a specified amount.
Ceded Reinsurance. In our title insurance business, we use reinsurance as part of our capital and risk management activities, including a loss portfolio transfer reinsurance agreement that transfers a portion of the risk associated with the legacy title insurance in our portfolio (insurance written prior to the acquisition of our title insurance subsidiary) to a third party up to a specified dollar limit. We also currently maintain an excess of loss policy with a third-party reinsurer that covers losses on our entire title insurance legacy portfolio above a specified limit.
Cybersecurity Risk Management
Information security is a significant operational risk for financial institutions such as Radian and includes the risk of loss resulting from cyber-attacks. In an effort to mitigate this risk, we have an Information Security Program that is dedicated to protecting our corporate data as well as data entrusted to us by our customers and partners. At the core of our program is a defense-in-depth strategy, which utilizes multiple layers of security controls to protect data and solutions.
We use the National Institute of Standards and Technology Cybersecurity Framework (the “NIST CSF”), as a guideline to manage our cybersecurity-related risk. The NIST CSF outlines information security measures and controls over five functions: Identify, Protect, Detect, Respond and Recover. We have developed key security services, including Enterprise Data Protection, Vulnerability Management and Application Security, Managed Threat Detection and Incident Response. We test our incident response readiness and reporting through tabletop exercises, external and internal penetration testing and continuous internal security testing in our efforts to ensure that risks and incidents are identified, escalated and communicated for appropriate remediation activities to reduce risk to an acceptable level.
Our commitment to growing and maintaining our Information Security Program extends across all business lines. We have an Information Security Committee comprised of Company executives, cross-functional Incident Response teams and strong governance mechanisms designed to ensure compliance with our security policies and protocols. See “Item 1A. Risk Factors—We could incur significant liability or reputational harm if the security of our information technology systems is breached, including as result of a cyberattack, or we otherwise fail to protect confidential information, including personally identifiable information that we maintain.”
Human Capital Management
For nearly 45 years at Radian, our products and services have responsibly helped millions of families achieve their dream of homeownership. This company-wide commitment to affordable and sustainable homeownership, along with our support of our customers and the communities where we live and work, defines who we are as an enterprise and aligns with our core organizational values: Deliver the Brand Promise, Innovate for the Future, Create Shareholder Value, Our People are the Difference, Do What’s Right and Partner to Win.
We value our employees by supporting a healthy work-life balance and a team-oriented, One Radian environment. We strive to offer competitive compensation and benefits programs as well as development opportunities, while fostering a community where everyone feels included and empowered to do their best work and is encouraged to give back to their communities to make a social impact. As of December 31, 2021, we had approximately 1,800 employees of Radian Group and its subsidiaries.
COVID-19 Response
In response to the COVID-19 pandemic, we took a number of actions to focus on protecting and supporting our workforce. We seamlessly transitioned to a work-from-home virtual workforce model and throughout 2021 continued to offer the flexibility of remote work options for most employees and safe in-office opportunities for those employees with a desire to work outside their homes. Those activities requiring in-office work were supported by limited staff in office environments that comply with CDC guidelines and applicable state and local requirements. These efforts were further supported through regular COVID-19 testing regimes. In order to promote our company culture and encourage frequent communication and camaraderie, we established frequent virtual connections through weekly CEO messages, CEO and senior management roundtables and employee surveys to encourage feedback.
We continue to reinforce our employee health and wellness benefits and mental health program resources by implementing benefit program changes to accommodate COVID-19-related leaves and hardships, amending our savings and retirement plans to comply with legislation that allows for greater flexibility in response to the pandemic and providing access to third-party caregiver and household support services.
30

Part I. Item 1. Business
During the second quarter of 2021, in response to Radian’s transition to a mainly virtual work environment and employees voicing their preference for increased flexibility and opportunities to work remotely, we made the decision to exit, and to actively market for sublease, all office space in our former corporate headquarters in downtown Philadelphia. As part of this change, we entered into two new leases with overall reduced square footage, including our new corporate headquarters in Wayne, Pennsylvania and a Cherry Hill, New Jersey location.
Compensation and Benefits Program
Our compensation programs are designed to attract, retain and reward talented individuals who possess the skills and qualities necessary to support our business objectives, demonstrate our values, assist in the achievement of our strategic goals and create long-term value for our stockholders. Our compensation programs include base salary, annual incentive bonuses and for certain employees, other performance-related cash-incentives such as commissions and long-term equity incentive awards.
Our annual short-term incentive or bonus program is designed and approved by the Compensation and Human Capital Management Committee of our board of directors to incent achievement of our financial objectives and execution of our strategic plan in alignment with our organizational values. Compliance with our values and efforts to advance our human capital management efforts are considered as part of our employees’ performance evaluations and are taken into consideration in determining each employee’s annual short-term incentive award.
In addition to our cash and equity compensation programs, we offer employees a comprehensive benefits package, including, among others, life and health (medical, dental and vision) insurance, paid time off, paid parental leave and caregiver leave, a 401(k) plan with an employer matching contribution and tuition reimbursement. In addition, in order to support our employees and advance our mission to promote affordable, sustainable homeownership, we offer all eligible employees the opportunity to save on Radian mortgage insurance with partial reimbursement of their mortgage insurance expense. We are exploring alternatives to expand upon this employee affinity program in 2022.
Diversity, Equity and Inclusion
At Radian, we are committed to an inclusive and diverse workplace, as represented by our theme We Are Many, We Are One Radian. We believe that an equitable and inclusive environment with diverse teams produces more creative solutions, results in better, more innovative products and services and is crucial to our efforts to attract and retain key talent.
In 2019, we established a Diversity, Equity and Inclusion (“DEI”) Council that is sponsored by our CEO, led by senior management and consists of leaders and employees from across the Company to advance the program and its efforts. In 2020, we created a framework for and launched Radian’s Employee Resource Group (“ERG”) program, which is an important aspect of Radian’s DEI efforts because it not only creates inclusive communities where employees feel support, but it enriches our overall company culture. These ERGs have taken root throughout 2021, and Radian currently has three active ERGs: TrueColors, which brings together our LGBTQIA+ employees and allies; Women Heard as our Women’s group; and Vibrant Crossroads, which highlights intersectionality and multiculturalism.
We are committed to providing equal employment opportunities and promoting inclusive hiring practices, developing targeted recruitment strategies and improving internal reporting capabilities. In 2020, we trained all managers on unconscious bias and, in 2021, we hired a recruiter dedicated to DEI and deployed mandatory DEI training for all employees. We also completed a pay equity analysis in partnership with an external expert to ensure an objective review of our pay practices. We are committed to enhancing our DEI maturity, and have developed our DEI Roadmap to execute our multi-year DEI strategy. Our roadmap commits us to progress, and we report on this progress to our workforce on a quarterly basis.
In terms of gender equality, Radian has been making strides in advancing women in the workplace and in December 2021 was recognized by the Bloomberg Gender Equality Index for the fourth consecutive year. At December 31, 2021, women represented 59.9% of our workforce, 44.4% of the direct reports to our Chief Executive Officer and 40.5% of our senior management team comprising officers at the Assistant Vice President level and above. In addition, based on the number of women on Radian Group’s board of directors, Radian was awarded a ‘W’ by 2020 Women on Boards for being a ‘winning company’ and was named one of the Forum of Executive Women’s 2021 Champions of Board Diversity.
Finally, we know that advancing a culture of inclusion takes every single employee. For 2022 goal setting, all employees have been asked to include a DEI goal in their goal plan. By focusing all employees on the importance of our DEI efforts, we can continue to advance a culture of inclusion and respect.
Talent Development and Employee Engagement
We invest in our people to provide opportunities for career growth. Talent development, annual performance reviews that are focused in part on living our company values and succession planning are all important aspects of this investment. These processes help management identify and nurture top talent for leadership opportunities and support the growth and development of knowledge and skills of Radian employees, managers and leaders.
31

Part I. Item 1. Business
In order to measure engagement and culture across the organization, we use employee experience surveys. Our most recent employee experience survey was conducted in 2021 with a 70% employee participation rate (versus a benchmark of 65%) and responses revealed an Engaged-to-Disengaged Ratio of 21.5 to 1 (versus a benchmark of 2.1 to 1). In addition to our experience surveys, we frequently use employee pulse surveys to gather employee feedback.
Community Involvement
Radian’s financial strength and growth depend on the well-being of our employees, and therefore, the communities in which they live and we operate. Our Corporate Citizenship Program was developed to encourage and support the generosity and community involvement of our employees. Since its inception, the program – through both company and employee contributions – has provided significant financial support to charities across the country. The program consists of three pillars: charitable contributions, matching gifts and community connection.
Following the onset of the COVID-19 pandemic, we implemented a number of initiatives to help alleviate the impact of the COVID-19 pandemic, including doubling our matching gift program for employees and passing on some of our savings from reduced travel and entertainment expenses to organizations supporting essential workers. Our community-based program, Radian Connected, provides opportunities for employee engagement and community involvement, including volunteerism and opportunities for learning and skill development, as well as social opportunities to network and build stronger working relationships. We believe that this commitment to our communities helps in our efforts to attract and retain employees.
Regulation
We are subject to comprehensive regulation by both federal and state regulatory authorities. Set forth below is a description of significant state and federal regulations and other requirements of the GSEs that are applicable to our businesses. The descriptions below are qualified in their entirety by reference to the full text of the laws and regulations discussed. In Item 1A. Risk Factors, see “—Our insurance subsidiaries are subject to comprehensive state insurance regulations and other requirements, which we may fail to satisfy” and “—Legislation and administrative and regulatory changes and interpretations could impact our businesses.”
State Regulation
Overview of State Insurance Regulation and Our Insurance Subsidiaries
We and our insurance subsidiaries are subject to comprehensive regulation by the insurance departments in the various states where they are licensed to transact business. Insurance laws vary from state to state, but generally grant broad supervisory powers to agencies or officials to examine insurance companies and enforce rules or exercise discretion affecting almost every significant aspect of the insurance business. These regulations principally are designed for the protection of policyholders, rather than for the benefit of investors.
Insurance regulations address, among other things, the licensing of companies to transact business, claims handling, reinsurance requirements, premium rates and policy forms offered to customers, financial statements, periodic reporting, permissible investments and adherence to financial standards relating to surplus, dividends and other measures of solvency intended to assure the satisfaction of obligations to policyholders.
Our insurance subsidiaries’ premium rates and policy forms are generally subject to regulation in every state in which they are licensed to transact business. These regulations are intended to protect policyholders against excessive, inadequate or unfairly discriminatory rates and to encourage competition in the insurance marketplace. In most states where our insurance subsidiaries are licensed, premium rates and policy forms must be filed with the state insurance regulatory authority and, in some states, must also be approved before their use.
With respect to mortgage insurance, premium rates may be subject to actuarial justification, generally on the basis of the mortgage insurer’s loss experience, expenses and future projections. In addition, states may assess how rates are being charged to various customers based on whether they are “similarly situated” and also may evaluate general default experience in the mortgage insurance industry in assessing the premium rates charged by mortgage insurers. In many states, the filed forms allow for a deviation from the filed rates within a certain range to take into consideration various factors linked to the credit being insured.
As to title insurance, premium rates and policy forms must be filed with state insurance regulatory authorities and, in some states, must also be approved before their use. Policy forms require approval to ensure that the coverage and exceptions conform to state insurance regulations. Premium rates subject to approval often must be supported by actuarial data or a study of financial impact of the premium rate on the Company. In September of 2017, the New York State Department of Financial Services (“DFS”) issued 11 NYCRR 228 (“Regulation 208”) which regulates title insurance marketing practices, expenses and transaction related charges in the state of New York. Regulation 208 limits or bans title underwriters and agents from charging consumers certain title- and closing-related fees, and Regulation 208 contains strict rules around marketing expenses aimed at restricting or stopping certain marketing practices in the title industry. While Regulation 208
32

Part I. Item 1. Business
currently is one of the most strict title marketing regulations, a number of other states impose similar restrictions on such activity, either through regulations that are specific to title marketing or through broader state insurance anti-inducement and anti-rebating laws. Radian Settlement Services and Radian Title Insurance have adjusted their transaction fees and marketing practices and expenses to comply with Regulation 208 and other similar state laws.
Each insurance subsidiary is required by the insurance regulatory authority of its state of domicile, and the insurance regulatory authority of each other jurisdiction in which it is licensed to transact business, to make various filings with those insurance regulatory authorities and with the NAIC, including quarterly and annual financial statements prepared in accordance with SAP. In addition, our insurance subsidiaries are subject to examination by the insurance regulatory authority of their state of domicile, as well as each of the states in which they are licensed to transact business.
Radian Group is an insurance holding company and our mortgage insurance subsidiaries and title insurance company belong to an insurance holding company system. We are subject to the insurance holding company laws of Pennsylvania and Ohio because all of our mortgage insurance subsidiaries are domiciled in Pennsylvania and Radian Title Insurance is domiciled in Ohio. These insurance holding company laws regulate, among other things, certain transactions between Radian Group, our insurance subsidiaries and affiliates. The holding company laws of Pennsylvania and Ohio also govern certain transactions involving Radian Group’s common stock, including transactions that constitute a “change of control” of Radian Group and, consequently, a “change of control” of its insurance subsidiaries. Specifically, no person may, directly or indirectly, seek to acquire “control” of Radian Group or any of its mortgage insurance subsidiaries unless that person received prior approval after filing a statement and other documents with the Pennsylvania Insurance Department and, in the case of a change of control involving Radian Group or Radian Title Insurance, the Ohio Department of Insurance. Under Pennsylvania’s and Ohio’s insurance statutes, “control” is defined broadly and is “presumed to exist if any person, directly or indirectly, owns, controls, holds with power to vote or holds proxies representing 10% or more of the voting securities” of a holding company of a Pennsylvania or Ohio domiciled insurer. The statute further defines “control” as the “possession, direct or indirect, of the power to direct or cause the direction of the management and policies of” an insurer.
In addition, material transactions between us or our affiliates and our insurance subsidiaries or among our insurance subsidiaries are subject to certain conditions, including that they be “fair and reasonable.” These conditions generally apply to all persons controlling, or who are under common control with, us or our insurance subsidiaries. Certain transactions between us or our affiliates and our insurance subsidiaries may not be entered into unless the Pennsylvania Insurance Department or Ohio Department of Insurance, as applicable, is given 30 days’ prior notice and does not disapprove the transaction during that 30-day period.
Our two principal mortgage insurance companies as of December 31, 2021 are:
Radian Guaranty – Radian Guaranty is our primary mortgage insurance company, and is a direct wholly-owned subsidiary of Radian Group. Radian Guaranty is our only mortgage insurance company that is currently eligible to provide first-loss mortgage insurance on GSE loans. It is a monoline insurer, restricted by the laws of certain states to writing first-lien residential mortgage guaranty insurance. Radian Guaranty is authorized to write mortgage guaranty insurance (or in states where there is no specific authorization for mortgage guaranty insurance, the applicable line of insurance under which mortgage guaranty insurance is regulated) in all 50 states, the District of Columbia and Guam.
Radian Reinsurance – Radian Reinsurance is a direct wholly-owned subsidiary of Radian Group and is a licensed credit insurer in Pennsylvania. We have used Radian Reinsurance to participate in the credit risk transfer programs developed by Fannie Mae and Freddie Mac, and therefore, Radian Reinsurance currently provides mortgage credit risk insurance on GSE loans through these programs. See “Mortgage—Mortgage Insurance Products—Other Mortgage Insurance Products—GSE Credit Risk Transfer” for more information about these programs.
We also have the following mortgage insurance subsidiaries: Radian Insurance, a direct wholly-owned subsidiary of Radian Group that insures a small amount of second-lien mortgage loan risk written prior to the financial crisis; and Radian Mortgage Assurance, a direct wholly-owned subsidiary of Radian Group which had no RIF as of December 31, 2021.
As part of our title services business, we offer title insurance through Radian Title Insurance, which we acquired in March 2018. Radian Title Insurance is an Ohio domiciled title insurance underwriter and settlement services company that is licensed to issue title insurance policies in 41 states and the District of Columbia. Radian Title Insurance is an indirect subsidiary of Radian Group and is wholly owned by Radian Title Services Inc.
Mortgage Insurance Capital Requirements and Dividends
Under state insurance regulations, Radian Guaranty is required to maintain minimum surplus levels and, in certain states, a Statutory RBC Requirement that is based on maximum ratio of net RIF relative to statutory capital, or Risk-to-capital. The most common Statutory RBC Requirement is that a mortgage insurer’s Risk-to-capital may not exceed 25 to 1, while in certain other RBC States, Radian Guaranty must satisfy a MPP Requirement. As of December 31, 2021, Radian Guaranty’s Risk-to-capital was 11.1 to 1, and Radian Guaranty was in compliance with all applicable Statutory RBC Requirements. See Note 16 of Notes to Consolidated Financial Statements for more information on statutory capital requirements, including potential changes under consideration by the NAIC to the minimum capital and surplus requirements for mortgage insurers included in the Model Act. The ultimate outcome of the Model Act and new capital framework remains uncertain, including the
33

Part I. Item 1. Business
form of requirements and how they may be implemented and potentially enforced. See “Item 1A. Risk Factors—Our insurance subsidiaries are subject to comprehensive state insurance regulations and other requirements, which we may fail to satisfy.”
Under Pennsylvania’s insurance laws, dividends and other ordinary distributions may only be paid out of an insurer’s positive unassigned surplus unless the Pennsylvania Insurance Department approves the payment of dividends or other distributions from another source. At December 31, 2021, Radian Guaranty had a negative unassigned surplus balance of $562.8 million, primarily due to the need for mortgage guaranty insurers to establish and maintain contingency reserves, as further discussed below. Therefore, no dividends or other ordinary distributions can be paid by Radian Guaranty without prior approval from the Pennsylvania Insurance Department.
For statutory reporting, mortgage insurance companies are required annually to set aside contingency reserves in an amount equal to 50% of earned premiums. The contingency reserve, which is designed to be a reserve against catastrophic losses, essentially restricts dividends and other ordinary distributions by mortgage insurance companies as such amounts cannot be released into surplus for a period of 10 years, except when loss ratios exceed 35%, in which case the amount above 35% can be released under certain circumstances.
In light of Radian Guaranty’s negative unassigned surplus and the ongoing need to set aside contingency reserves, we do not anticipate that Radian Guaranty will be permitted under applicable insurance laws to pay ordinary dividends to Radian Group for the next several years. However, under Pennsylvania’s insurance laws, an insurer may request to pay an Extraordinary Distribution, subject to the approval of the Pennsylvania Insurance Department. See Note 16 of Notes to Consolidated Financial Statements for more information on contingency reserve requirements and statutory dividend restrictions, as well as additional information about distributions of capital paid from our insurance subsidiaries in recent years and the approval in February 2022 of a $500 million return of capital from Radian Guaranty to Radian Group.
Title Insurance Capital Requirements and Dividends
Radian Title Insurance is required to maintain Statutory Premium Reserves (“SPR”), calculated as a percentage of gross premiums collected. The SPR requirements are set by each state, with the most common being 7%. The SPR is then recovered based on a release schedule, amortized over 20 years. In addition to the SPR, Radian Title Insurance is subject to periodic reviews of certain financial performance ratios, and the states in which it is licensed can impose capital requirements on Radian Title Insurance based on the results of those ratios.
Under Ohio’s insurance laws, dividends and other ordinary distributions may only be paid out of an insurer’s positive unassigned surplus unless the Ohio Department of Insurance approves the payment of dividends or other ordinary distributions from another source. While all proposed dividends and distributions to stockholders must be filed with the Ohio Department of Insurance prior to payment, if an Ohio domiciled insurer had positive unassigned surplus, such insurer can pay dividends or other distributions during any 12-month period in an aggregate amount less than or equal to the greater of: (i) 10% of the preceding year-end statutory policyholders’ surplus or (ii) the preceding year’s statutory net income, in each case without the prior approval of the Ohio Department of Insurance. Radian Title Insurance had negative unassigned surplus at December 31, 2021 of $13.8 million, therefore it is unable to pay dividends or other ordinary distributions without prior approval from the Ohio Department of Insurance.
Other Services
In addition to our insurance subsidiaries, certain of our other subsidiaries are subject to regulation and oversight by the states where they conduct their businesses, including requirements to be licensed and/or registered in the states in which they conduct operations.
Our real estate brokerage business conducted through Red Bell provides services in all 50 states and the District of Columbia, and Red Bell and its designated broker in each state are required to hold licenses and conduct their brokerage business in conformity with the applicable license laws and administrative regulations of the states in which they are conducting their business. As a licensed real estate brokerage, Red Bell receives residential real estate information from various multiple listing services (“MLS”) through agreements with these MLS providers, which it uses to broker real estate transactions and provide valuation products and services, pursuant to the terms of these agreements. These MLS agreements include restrictions on the permitted use of the MLS information obtained through these agreements and impose requirements on the business of real estate brokerages in order to maintain eligibility to continue to receive the MLS information. If these agreements were to terminate or Red Bell otherwise were to lose access to this information, it could negatively impact Red Bell’s ability to conduct its business.
Radian Mortgage Capital LLC (“RMC”) is an indirect wholly-owned subsidiary of Radian Group that has been formed as a vehicle for exploring opportunities to leverage our industry knowledge and customer relationships to opportunistically expand our channels for aggregating, managing and distributing mortgage credit risk, including potentially purchasing residential mortgage loans and issuing residential mortgage-backed securities. RMC is not yet conducting business, but is licensed in 14 states and positioned to purchase and hold residential mortgages on a nationwide basis. See “Item 1A. Risk Factors—Investments to grow our existing businesses, pursue new lines of business or new products and services within existing lines of business subject us to additional risks and uncertainties.”
34

Part I. Item 1. Business
Radian Lender Services LLC provides third-party underwriting and loan processing services to lenders. This entity and its employees that provide our contract underwriting and loan processing services are eligible to provide these services in compliance with the SAFE Act for underwriting in all 50 states and the District of Columbia and in compliance with loan processing requirements in 45 states and the District of Columbia. See “—Federal Regulation—The SAFE Act.”
Radian Settlement Services and its subsidiaries provide title and escrow services and these entities are required to hold licenses in the jurisdictions where they operate their business. Title insurance agency and escrow licensing is primarily regulated by states in which the services are being offered, with licensing and registration typically within the jurisdiction of each state’s department of insurance. Radian Settlement Services is domiciled and licensed in Pennsylvania as a resident title insurance agency and, together with its subsidiaries, is licensed in 43 additional states.
Radian Valuation Services LLC is an appraisal management company, licensed in all 50 states and the District of Columbia, that supports certain valuation services provided by Red Bell. Real estate appraisal management statutes and regulations vary from state to state, but generally grant broad supervisory powers to agencies or officials to examine companies and enforce rules. While these businesses are generally state regulated, the Dodd-Frank Act established minimum requirements to be implemented by states regarding the registration and supervision of appraisal management companies. Most states have based their legislation on model legislation developed by the Appraisal Institute for the registration and oversight of appraisal management companies.
Information Security
The DFS issued cybersecurity regulations known as “Part 500” that became effective March 1, 2017 and apply to all financial institutions and insurance companies licensed under the New York Banking, Insurance, and Financial Services Laws, including Radian Guaranty and certain of our other subsidiaries. The regulations require covered entities to, among other things: establish a cybersecurity program; adopt a written cybersecurity policy; designate a Chief Information Security Officer responsible for implementing, overseeing and enforcing the cybersecurity program and policy; and have policies and procedures designed to ensure the security of information systems and nonpublic information accessible to, or held by, third-parties, along with a variety of other requirements to protect the confidentiality, integrity and availability of information systems. Also in 2017, the NAIC issued an Insurance Data Security Model Law, which was modelled after Part 500, and which several states have adopted. The stated intention of that Model Law is that if a covered insurance company is compliant with Part 500, it also would be in compliance with the NAIC Insurance Data Security Model Law.
Privacy
The State of California enacted the California Consumer Privacy Act (“CCPA”), which became effective in 2020 and applies to any company that does business in California and meets certain threshold requirements. We believe Radian Group and certain of its affiliates may be deemed covered businesses under the CCPA.
The CCPA creates a new privacy framework for covered businesses that collect, sell or disclose personal information of California consumers. Companies subject to the CCPA are required to establish procedures to enable them to comply with a California consumer’s data privacy rights, including by disclosing the privacy practices of the entity and responding to consumer requests within prescribed timeframes. The CCPA provides a private right of action for data breaches, including statutory or actual damages, and public enforcement by the California Attorney General for other violations.
On November 3, 2020, California voters approved a ballot initiative known as Proposition 24, which created a new privacy law known as the California Privacy Rights Act (“CPRA”). The CPRA is designed to enhance certain of the privacy protections for California consumers that were created by the CCPA. Although most of the CPRA’s provisions will not go into effect until January 1, 2023, the CPRA is an expansive privacy law which will create additional compliance obligations for covered entities.
We have put policies and procedures in place to comply with the CCPA. In addition to California, other states have started to move forward with new privacy regulations and federal regulators have proposed draft federal privacy legislation, all of which, to the extent they are adopted, could impose additional compliance obligations on covered entities beyond those currently in effect and could impact our businesses or those of our customers. The earliest that these other laws are scheduled to go into effect is January 2023.
Federal Regulation
CARES Act
Since the outbreak of the pandemic, there have been a number of governmental efforts to implement programs designed to assist individuals and businesses impacted by the COVID-19 virus, including the CARES Act that was enacted on March 27, 2020. The CARES Act provided a temporary foreclosure and eviction moratorium for residential mortgagors with certain federally- or GSE-backed mortgages. After being extended multiple times, the GSEs’ moratorium on single-family real estate owned (REO) evictions expired on September 30, 2021. The GSEs’ moratoriums on most single-family foreclosures also were

extended multiple times before expiring December 31, 2021, which was the expiration date of the foreclosure moratorium imposed by the CFPB.
In addition, under the CARES Act, upon request by borrowers of federally-backed mortgage loans who attest to financial hardship related to the pandemic, mortgage servicers are required to provide these borrowers with up to 180 days forbearance on their mortgage payments, which may be extended for an additional 180 days upon request, without requiring validation by the borrowers of their hardship. The CARES Act provides no end date for when the 180 days forbearance must initially be offered. The permissible forbearance period of 12 months under the CARES Act has been lengthened by various federal agencies and the length of the period varies depending on the agency and type of mortgage at issue. For example, the GSEs extended the allowable forbearance period from 12 months to 18 months for those borrowers who were in an active COVID-19-related forbearance program as of February 28, 2021.
The GSEs have announced that, at the end of a forbearance plan, the homeowner may not be required to pay back their reduced or suspended mortgage payments in one lump sum, but may be eligible for a number of different options offered by their mortgage servicer, including repayment plans, resuming normal payments or lowering the monthly loan payment through a modification. For additional information on the potential impacts of the CARES Act on the GSEs, loan servicers and our PMIERs financial requirements, in Item 1A. Risk Factors, see “—Radian Guaranty may fail to maintain its eligibility status with the GSEs, and the additional capital required to support Radian Guaranty’s eligibility could reduce our available liquidity,” “—Changes in the charters, business practices or role of the GSEs in the U.S. housing market generally, could significantly impact our businesses,” and “—Our business depends, in part, on effective and reliable loan servicing.”
GSE Requirements for Mortgage Insurance Eligibility
As the largest purchasers of conventional mortgage loans, and therefore, the main beneficiaries of private mortgage insurance, the GSEs impose eligibility requirements that private mortgage insurers must satisfy in order to be approved to insure loans purchased by the GSEs. The PMIERs initially became effective December 31, 2015 and aim to ensure that approved insurers will possess the financial and operational capacity to serve as strong counterparties to the GSEs throughout various market conditions. The PMIERs are comprehensive, covering virtually all aspects of the business and operations of a private mortgage insurer of GSE loans, including internal risk management and quality controls, the relationship between the GSEs and the approved insurer and the approved insurer’s financial condition. The PMIERs contain extensive requirements related to the conduct and operations of our mortgage insurance business, including operational requirements in areas such as claim processing, loss mitigation, document retention, underwriting, quality control, reporting and monitoring, among others. Radian Guaranty currently is an approved mortgage insurer under the PMIERs.
The PMIERs’ financial requirements require that a mortgage insurer’s Available Assets meet or exceed its Minimum Required Assets. The PMIERs’ financial requirements include increased financial requirements for defaulted loans, as well as for performing loans with a higher likelihood of default and/or certain credit characteristics, such as higher LTVs and lower FICO credit scores. With respect to defaulted loans, the PMIERs recognize that loans that have become non-performing as a result of a FEMA Declared Major Disaster generally have a higher likelihood of curing following the conclusion of the event and therefore applies a Disaster Related Capital Charge to reduce the Minimum Required Asset factor for these loans.
In 2020, in response to the COVID-19 pandemic, the GSEs issued guidelines (“National Emergency Guidelines”) that became effective June 30, 2020 and, among other things, adopted the COVID-19 Amendment to the PMIERs to apply the Disaster Related Capital Charge nationwide to certain non-performing loans that we refer to as COVID-19 Defaulted Loans, which comprise non-performing loans that either: (i) have an Initial Missed Payment occurring during the COVID-19 Crisis Period or (ii) are subject to a forbearance plan granted in response to a financial hardship related to COVID-19 (which is assumed under the COVID-19 Amendment to be the case for any loan that has an Initial Missed Payment occurring during the COVID-19 Crisis Period and is subject to a forbearance plan), the terms of which are materially consistent with the terms of forbearance plans offered by the GSEs.
Under the COVID-19 Amendment, the Disaster Related Capital Charge applies for three calendar months beginning with the month the loan becomes non-performing (i.e., missed two monthly payments), or if greater, the period of time that the loan is subject to a forbearance plan, repayment plan or loan modification trial period granted in response to a financial hardship related to COVID-19. After being extended once in December 2020, the COVID-19 Crisis Period expired as of March 31, 2021. As a result, as of April 1, 2021, the Disaster Related Capital Charge is no longer applied to all new defaults, and instead is applied only to new defaults if they are subject to a COVID-19 forbearance plan, regardless of whether the forbearance plan was entered into before or after the expiration of the COVID-19 Crisis Period.
The Disaster Related Capital Charge will continue to be applied to these COVID-19 Defaulted Loans for as long as they remain in the COVID-19 forbearance plan, repayment plan or loan modification trial period. Further, if the National Emergency Guidelines and the COVID-19 Amendment are terminated, the Disaster Related Capital Charge would then be applied to defaulted loans in accordance with the PMIERs’ provision pertaining to loans that have become non-performing as a result of a FEMA Declared Major Disaster, to the extent these provisions are still applicable in the state where the property is located. See “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources—Mortgage.”

Part I. Item 1. Business
In addition to the increased financial requirements for defaulted loans and certain performing loans, the PMIERs financial requirements also impose limitations on the credit that is granted for certain Available Assets. For example, the PMIERs limit the amount of credit given to surplus notes issued by a mortgage insurer to 9% of Minimum Required Assets. In addition, the PMIERs prohibit Radian Guaranty from engaging in certain activities such as insuring loans originated or serviced by an affiliate (except under certain circumstances) and require Radian Guaranty to obtain the prior consent of the GSEs before taking many actions, which may include, among other things, entering into various intercompany agreements, settling loss mitigation disputes with customers and commuting risk.
The GSEs have significant discretion under the PMIERs and may amend the PMIERs at any time, although the GSEs have communicated that for material changes, including large-scale material changes affecting Minimum Required Assets, they will generally provide written notice 180 days prior to the effective date and engage in a discussion and comment process with the private mortgage insurers regarding the proposed changes prior to finalizing them. The most recent large-scale revisions to PMIERs, or PMIERs 2.0, became effective on March 31, 2019, and the PMIERs were further updated in June 2020 to specifically address the COVID-19 pandemic.
It is possible that the GSEs may seek to amend PMIERs 2.0 in the future to align the financial requirements of the PMIERs with the capital requirements for the GSEs set forth in the ECF. The ECF was finalized in December 2020, but further potential changes have since been publicly proposed and are under evaluation by the FHFA. See “Housing Finance Reform and the GSEs’ Business Practices” below for additional information on the ECF.
As part of our capital and risk management activities, including to manage Radian Guaranty’s capital position under the PMIERs financial requirements, we have distributed risk through third party quota share and excess-of-loss reinsurance arrangements, including through the capital markets using insurance-linked-notes transactions. The initial and ongoing credit that we receive under the PMIERs financial requirements for these risk distribution transactions is subject to the periodic review of the GSEs and could be influenced by the ECF which, as finalized in December 2020, provides the GSEs with a reduced amount of credit for their own credit risk transfer activities.
See “Item 1A. Risk Factors—Radian Guaranty may fail to maintain its eligibility status with the GSEs, and the additional capital required to support Radian Guaranty’s eligibility could reduce our available liquidity.”
Housing Finance Reform and the GSEs’ Business Practices
Legislative Reform
The federal government plays a significant role in the U.S. housing finance system through, among other things, the involvement of the FHFA and GSEs, the FHA and the VA. The GSEs’ charters, which cannot be altered outside of federal legislation, generally prohibit them from buying low down payment mortgage loans without certain forms of credit enhancement, the most common form of which has been private mortgage insurance.
Since FHFA was appointed as conservator of the GSEs in September 2008, there has been a wide range of legislative proposals to reform the U.S. housing finance market, including proposals for GSE reform ranging from some that advocate nearly complete privatization and elimination of the role of the GSEs to others that support a system that combines a federal role with private capital. While many legislative proposals have been debated and occasionally advanced through various legislative procedures, no reform proposal has reached an advanced legislative stage. As a consequence, most reform related actions with respect to the housing finance system have occurred administratively through regulatory actions.
Administrative Reform
The executive branch of the government (the “Administration”), typically through its Departments and regulatory agencies, offers perspectives on the future of housing finance in the U.S., including objectives for future strategic direction and areas of focus. As a result, a change in Administrations can significantly alter the strategic direction of housing finance in the U.S.
Although many Departments or agencies impact housing finance in some manner, the most prominent and directly impactful are the FHFA, HUD, the U.S. Department of the Treasury (“Treasury”) and the CFPB. In June 2021, following a Supreme Court decision that determined that the FHFA director may be removed by the President other than for cause, President Biden removed the FHFA director appointed by President Trump and appointed Sandra Thompson as acting director of the FHFA. Since assuming the role of acting director of the FHFA, Ms. Thompson has taken a number of actions that represent a reversal of the previous FHFA leadership’s primary focus on preparing the GSEs to exit from conservatorship by increasing the GSEs’ overall capital levels and reducing their credit risk profile. In contrast, the FHFA under acting director Thompson has been focused on increasing the accessibility and affordability of mortgage credit, in particular to low- and moderate-income borrowers and underserved communities, in addition to ensuring the safety and soundness of the GSEs. The Supreme Court’s decision providing that the FHFA director may be removed by the President without cause creates a higher likelihood that the direction of the FHFA and its oversight over the GSEs may be impacted by elections and the then political leanings of the Administrations in power than previously was the case.
Senior Preferred Stock Purchase Agreements. The Treasury currently owns the preferred stock of the GSEs pursuant to the terms of PSPAs, and therefore, has significant influence over the fate and direction of the GSEs. Prior to a December
37

Part I. Item 1. Business
2017 amendment to the PSPAs, which allowed each GSE to retain a $3 billion capital reserve, the GSEs were required under the PSPAs to sweep all profits to Treasury. In September 2019, Treasury and the FHFA further amended the PSPAs to suspend the quarterly “net worth sweep” and allow the GSEs to build a capital reserve of up to $45 billion collectively, and in January 2021, prior to the change in Administration, the PSPAs were amended again to allow the GSEs to continue to retain capital up to the amounts prescribed in newly revised GSE capital requirements, pursuant to the ECF and as discussed below.
As part of the January 2021 amendment to the PSPAs, the Trump appointed leadership in Treasury and FHFA also agreed that the GSEs must restrict their acquisition of higher-risk single-family mortgage loans, including in particular the acquisition of investor loans and single-family mortgage loans with two or more higher risk characteristics (i.e., LTVs greater than 90%, debt-to-income ratios greater than 45% and FICO credit scores less than 680), to their then current levels. The January 2021 PSPA amendment further restricted the quality of loans that may be purchased by the GSEs by limiting the GSEs’ purchases to, among other enumerated types, loans that meet the QM definition. In September 2021, the Biden appointed leadership in Treasury and the FHFA suspended the limitations on GSE purchases of loans deemed higher risk, set forth in the January 2021 amendments to the PSPAs.
Enterprise Capital Framework. Throughout 2020, under the Trump appointed leadership, the FHFA advanced certain initiatives to develop new capital and liquidity requirements for the GSEs, which were viewed as critical to any future release of the GSEs from conservatorship. In December 2020, the FHFA finalized a new ECF for the GSEs and also proposed new liquidity requirements.
Among other things, as compared to the prior version of the ECF, the ECF finalized in 2020: (i) significantly increased the capital requirements of the GSEs; (ii) decreased the capital credit provided to the GSEs for credit risk transfer transactions, which have been a significant component of the GSEs capital and risk management strategy for the past several years; and (iii) reduced the overall capital relief extended to the GSEs for loans with private mortgage insurance.
In December 2020, the FHFA also proposed new liquidity requirements for the GSEs, which impose a mix of new cash-flow based requirements and long-term liquidity and funding requirements. The liquidity requirements were proposed to be effective in September 2021, but to date have not been adopted. Under acting director Thompson, the FHFA evaluated the ECF that was finalized in 2020 for further changes, and in September 2021 proposed changes that would have the effect of reducing the GSEs’ total capital requirements from those finalized, including by giving greater credit to credit risk transfer. In December 2021, the FHFA also issued a proposed rule that would require the GSEs to submit annual capital plans to the FHFA and to provide the agency with advance notification of certain capital activities.
The ECF and proposed new liquidity requirements could significantly alter the business practices and operations of the GSEs. There are many considerations related to financial, underwriting, risk management, counterparty and operational areas that likely will need to be addressed by the GSEs in order to come into compliance with the ECF new capital requirements and the proposed liquidity requirements, regardless of the form ultimately adopted, which could have a material effect on the conventional mortgage market and potentially our business with the GSEs.
Access and Affordability. The Biden Administration has proposed a housing plan focused on: (i) increasing access to sustainable homeownership and making housing more affordable for low- and moderate-income borrowers; (ii) ensuring the housing finance system is equitable, by identifying and eliminating discriminatory or unfair practices in the housing system; (iii) increasing the supply, lowering the cost and improving the quality of housing, including through investments in resilience, energy efficiency, and accessibility of homes; and (iv) providing financial assistance to help Americans buy or rent safe, quality housing, including down payment assistance.
Since assuming leadership over the FHFA in June 2021, in addition to amending the PSPAs and proposing revisions to the ECF, the Biden appointed FHFA leadership team has instituted changes to further advance mortgage access and affordability, including the following actions:
In August 2021, entered into a memorandum of understanding with HUD to collaborate in addressing fair housing and fair lending;
In August 2021, cancelled a 50-basis point adverse market fee on refinance transactions;
In October 2021, raised the area median income limitations from 80% to 100% for the GSEs’ special refinance programs aimed at supporting low- and moderate-income borrowers’ ability to take advantage of the low interest rate environment; and
In October 2021, announced that “desktop appraisals,” which represent an alternative to traditional home appraisals, would be incorporated into the GSEs’ guidelines for many new purchases beginning in early 2022.
In addition to these actions, the FHFA has requested the GSEs to produce three-year plans focused on equitable housing.
Radian Guaranty and other private mortgage insurance companies have been engaged in discussions with the GSEs regarding how the industry may support the GSEs to advance these objectives. Depending on the outcome of such dialogue, one or both of the GSEs, together or in conjunction with one or more private mortgage insurers, could implement further initiatives in pursuit of housing policy objectives that could require changes to the GSEs’ business practices and impact our
38

Part I. Item 1. Business
businesses. See “Item 1A. Risk Factors—Changes in the charters, business practices, or role of the GSEs in the U.S. housing market generally, could significantly impact our businesses.
New Products. In October 2020, the FHFA leadership released for comment a proposed rule regarding the process for how it will consider and approve new GSE activities and products. Among other things, the proposed rule would redefine criteria for determining what constitutes a new activity that requires prior notice to the FHFA and for determining whether the activity constitutes a “new product” that requires public notice and comment, describing a new product as “any new activity that FHFA determines merits public notice and comment on matters of compliance with the applicable sections of [a GSE’s] authorizing statute, safety and soundness, or public interest.” Given the size and market influence of the GSEs, this new proposed rule is generally viewed as important to ensure that the GSEs are not otherwise encroaching on areas that may be more appropriately served by private capital.
It is difficult to predict what types of new products and activities may be proposed in the future and, if applicable, whether they may be approved by the FHFA. For example, if any existing or future credit risk transfer transactions and structures were to displace primary loan level or standard levels of mortgage insurance, the amount of mortgage insurance we write may be reduced, which could negatively impact our franchise value, results of operations and financial condition.
In 2018, Freddie Mac and Fannie Mae announced the launch of pilot programs, IMAGIN and EPMI, respectively, as alternative ways for lenders to obtain credit enhancement and sell loans with LTVs greater than 80% to the GSEs. These investor-paid mortgage insurance programs, in which insurance was acquired directly by each GSE through entities that were not subject to compliance with the PMIERs, have many of the same features as private mortgage insurance and represent an alternative to traditional private mortgage insurance products that are provided to individual lenders. These programs experienced limited volumes and in June 2021 were discontinued for new business, although they could be relaunched in the future. Further, the proposed rule regarding new products states that it is intended to apply to any future pilot programs, so it is unclear whether the same standards and procedures proposed in the new rule also would apply to existing pilots such as IMAGIN and EPMI if they are relaunched.
COVID-19. In addition to the matters discussed above, the future of the GSEs is likely to continue to be impacted by the ongoing COVID-19 pandemic. In light of the COVID-19 pandemic, the FHFA has adjusted its oversight over the GSEs to ensure the GSEs are able to support borrowers impacted by the pandemic and protect the ongoing functioning of the housing finance system.
In response to the pandemic, the FHFA and the GSEs temporarily suspended all foreclosures and evictions; temporarily instituted mortgage forbearance; temporarily streamlined the appraisal, employment verification and loan closing processes to address frictions in the mortgage origination process created by social distancing and stay-at-home orders; implemented a four-month limit on servicer advance obligations for loans in forbearance; adopted the COVID-19 Amendment to the PMIERs effective June 30, 2020; and provided that loans in COVID-19 forbearance will remain in mortgage-backed securities pools for at least the duration of the forbearance. To assist borrowers exiting COVID-19 forbearance plans, the GSEs have also provided options to address forborne payments, which include payment deferral, borrower repayment plans and loan modifications. The GSEs have updated servicer guidelines regarding options specific to COVID-19-related forbearance, including borrower eligibility for these programs.
In June 2021, the CFPB issued a final rule amending Regulation X, which provides servicers with the option to provide certain streamlined loan modification options to borrowers based on the evaluation of an incomplete loss mitigation application for those with COVID-19-related hardships. This rule also addresses temporary servicer communication requirements for borrowers approaching the end of a COVID-19 forbearance plan.
As the situation continues to evolve, the actions or potential inactions of the FHFA and GSEs in response to COVID-19 are likely to continue to have a significant impact on the overall functioning of the housing finance system. In Item 1A. Risk Factors, see “—Changes in the charters, business practices or role of the GSEs in the U.S. housing market generally, could significantly impact our businesses” and —Our mortgage insurance business faces intense competition.
HUD/FHA
Private mortgage insurance competes for a share of the insurable mortgage market with the single-family mortgage insurance programs of the FHA, including on the basis of loan limits, pricing, credit guidelines, terms of our insurance policies and loss mitigation practices.
Since the financial crisis, the private mortgage insurance industry has improved its share of the insurable, low down payment market, primarily due to: (i) improvements in the financial strength of private mortgage insurers; (ii) the development of new products, pricing delivery tools and marketing efforts directed at competing with FHA programs and execution; (iii) increases in the FHA’s pricing; (iv) the U.S. government’s pursuit of legal remedies against FHA-approved lenders related to loans insured by the FHA; and (v) various policy changes at the FHA, including the general elimination of the premium cancellation provision that still exists for borrower-paid private mortgage insurance.
As discussed above, the Biden Administration has been pursuing actions that will further its stated objective of increasing access to affordable mortgages for low- and moderate-income borrowers. In this regard, the Biden Administration may choose to reduce the FHA’s annual or upfront premiums and/or eliminate the life-of-loan premium requirement for FHA
39

Part I. Item 1. Business
insured loans. It is uncertain if and when the FHA may change its pricing and what form this price reduction could take; however, any change in the FHA’s pricing that would improve FHA execution compared to execution through the GSEs with private mortgage insurance could negatively impact our NIW volume.
As last reported in November 2021, the FHA’s Mutual Mortgage Insurance (MMI) Fund had a combined capital ratio for fiscal year 2021 of 8.03%, above the 2% ratio that the FHA is required to maintain. While this would suggest that it may be more likely that the FHA will lower pricing, the pandemic has had a significant negative impact on the FHA’s insured portfolio, including a significant increase in the total percentage of severely delinquent loans, making it more difficult to predict any future pricing actions the FHA may pursue.
In addition, in 2019, HUD issued a Memorandum of Understanding (“MOU”) with the Department of Justice (“DOJ”) that provides guidance on the process for enforcing the False Claims Act (“FCA”), and revisions of annual and loan-level certifications which became effective January 1, 2020. The MOU provides that alleged violations of the FCA will be primarily addressed through HUD administrative proceedings and only referred to the DOJ under certain circumstances. While we do not believe the MOU has had a significant impact on the pool of lenders doing business with the FHA, it could make the FHA more attractive to lenders who previously reduced their business with the FHA because of concerns regarding the DOJ’s pursuit of legal remedies against FHA lenders.
The Dodd-Frank Act
The Dodd-Frank Act mandates significant rulemaking by several regulatory agencies to implement its provisions. The Dodd-Frank Act established the CFPB to regulate the offering and provision of consumer financial products and services under federal law, including residential mortgages, and transferred authority to the CFPB to enforce many existing consumer related federal laws, including the Truth in Lending Act and RESPA.
Among the most significant provisions for private mortgage insurers under the Dodd-Frank Act are the ability to repay mortgage provisions (“Ability to Repay Rule”), including a related safe harbor set forth in the QM Rule (defined below), the securitization risk retention provisions and the expanded mortgage servicing requirements under the Truth in Lending Act and RESPA.
Qualified Mortgage Requirements—Ability to Repay Requirements
The Ability to Repay Rule requires mortgage lenders to make a reasonable and good faith determination that, at the time the loan is consummated, the consumer has a reasonable ability to repay the loan. The Dodd-Frank Act provides that a creditor may presume that a borrower will be able to repay a loan if the loan has certain low-risk characteristics that meet the definition of a qualified mortgage (“QM Rule”). This QM presumption is generally rebuttable, however, loans that are deemed to have the lowest risk profiles are granted a safe harbor from liability (“QM Safe Harbor”) related to the borrower’s ability to repay the loan.
In implementing the QM Rule, the CFPB established rigorous underwriting and product feature requirements for loans to be deemed qualified mortgages (“Original QM Definition”), including that the borrower does not exceed a 43% debt-to-income ratio after giving effect to the loan. As part of the Original QM Definition, the CFPB also created a special exemption for the GSEs, which is generally referred to as the “QM Patch,” that allows any loan that meets the GSE underwriting and product feature requirements to be deemed to be a qualified mortgage, or QM, regardless of whether the loan exceeds the 43% debt-to-income ratio.
In December 2020, the CFPB finalized two new definitions of QM. One of these new QM definitions (the “New General QM Definition”) is intended to replace the underwriting focused approach of the Original QM Definition, including the 43% debt-to-income ratio limitation, with a new pricing-based approach to QM. Under the New General QM Definition, certain underwriting considerations are retained, but QM status generally is achieved if the loan is priced at no greater than 2.25% above the Average Prime Offer Rate (“APOR”). Loans priced at or less than 1.5% above APOR are subject to the QM Safe Harbor, while all other QM loans would receive the general rebuttable presumption that the loans met the ability to repay standard.
Separately, the CFPB created another new QM definition (“Seasoned QM”) for first-lien, fixed-rate loans that meet certain performance requirements over a 36-month seasoning period and are held in the lender’s portfolio until the end of the seasoning period. Both new QM definitions became effective on March 1, 2021. The New General QM Definition originally had a mandatory compliance date of July 1, 2021, after which the Original QM Definition and QM Patch would no longer apply. In April 2021, the CFPB issued a new rule delaying the mandatory compliance deadline for the New General QM Definition until October 1, 2022, thereby preserving the Original QM Definition and QM Patch until such date.
On April 8, 2021, the GSEs announced that for loan applications received on or after July 1, 2021, they will only purchase loans satisfying the New General QM Definition. As a result, even though the CFPB has delayed the mandatory compliance date for the New General QM Definition until October 1, 2022, for GSE-acquired loans with applications received on or after July 1, 2021, the QM Patch is effectively limited to loans that satisfy the New General QM Definition. This decision by the GSEs reduced the number of loans that otherwise would have been designated QM compared to those receiving QM designation under the QM Patch, although not materially.
40

Part I. Item 1. Business
The QM Rule requires that points and fees paid at or prior to closing cannot exceed 3% of the total loan amount, with higher points and fees thresholds provided for loan amounts below $114,847. Any mortgage insurance premiums paid by the borrower at or before the time of loan closing must be applied toward the 3% points and fee calculation, unless such premiums are in excess of the FHA upfront premium amount and are automatically refundable on a pro-rata basis. There are no similar restrictions on the points and fees associated with FHA premiums, and thus FHA has a market advantage for smaller balance loans where the 3% cap is more easily reached.
The Dodd-Frank Act also granted the FHA, VA and the USDA flexibility to establish their own definitions of qualified mortgages for their insurance guaranty programs. Both the FHA and VA have created their own definition of qualified mortgages that differ from both the CFPB’s Original QM Definition and New General QM Definition. For example, the FHA’s QM Safe Harbor definition currently applies to loans priced at or less than APOR plus the sum of 115 basis points and the FHA’s annual mortgage insurance premium rate, which is effectively broader than the QM Safe Harbor adopted under the New General QM Definition. These alternate definitions of qualified mortgages are more favorable to lenders and mortgage holders than the CFPB’s Original QM Definition and the New General QM Definition that apply to loans purchased by the GSEs, which could drive business to these agencies and have a negative impact on our mortgage insurance business.
For more information regarding the CFPB’s proposed New General QM Definition and the risks it may present for us, see “Item 1A. Risk Factors—A decrease in the volume of mortgage originations could result in fewer opportunities for us to write new mortgage insurance business and conduct our homegenius business.
Qualified Residential Mortgage Regulations—Securitization Risk Retention Requirements
The Dodd-Frank Act requires securitizers to retain at least 5% of the credit risk associated with mortgage loans that they transfer, sell or convey, unless the mortgage loans are qualified residential mortgages (“QRMs”) or are insured by the FHA or another federal agency (the “QRM Rule”). Under applicable federal regulations, a QRM is generally defined as a mortgage meeting the requirements of a qualified mortgage under the CFPB’s QM Rule described above. Because of the capital support provided by the U.S. government to the GSEs, the GSEs currently satisfy the proposed risk retention requirements of the Dodd-Frank Act while they are in conservatorship, so sellers of loans to the GSEs currently are not subject to the risk retention requirements referenced above. This means that securitizers would not be required to retain risk under the QRM Rule on loans that are guaranteed by the GSEs while in conservatorship.
The QRM Rule requires the agencies that implemented the rule to review the QRM definition no later than four years after its effective date (i.e., December 2018) and every five years thereafter, and allows each agency to request a review of the definition at any time. On December 20, 2019, the Office of the Comptroller of the Currency, the Board of Governors of the Federal Reserve System, the Federal Deposit Insurance Corporation, the SEC, the FHFA and HUD announced the commencement of a review of the QRM Rule. In December 2021, following completion of this review, the agencies released the findings of this review and determined not to propose any changes to the definition of qualified residential mortgage at this time.
Other
The Dodd-Frank Act establishes a Federal Insurance Office within the U.S. Department of the Treasury (the “FIO”). While the FIO does not have a general supervisory or regulatory authority over the business of insurance, the director of this office performs various functions with respect to insurance, such as serving as a non-voting member of the Financial Stability Oversight Council. It is difficult to predict whether legislators or other executive agencies will pursue the development and implementation of federal standards for the mortgage insurance industry outside of the FHFA. Any divergence from the current system of state regulation could significantly change compliance burdens and possibly impact our financial condition.
In addition, Section 1473 of the Dodd-Frank Act establishes minimum requirements to be implemented by states regarding the registration and supervision of appraisal management companies (“AMCs”), including Radian Valuation Services. In 2015, six federal regulatory agencies (the Office of the Comptroller of the Currency, Federal Reserve Board, Federal Deposit Insurance Corporation, National Credit Union Administration, CFPB and the FHFA) approved final rules creating federal minimum requirements for state registration and supervision of AMCs.
All AMCs subject to state registration, including Radian Valuation Services, must satisfy certain minimum standards, including requirements to: (i) establish and comply with processes and controls designed to ensure that an AMC only engages an appraiser who has the appropriate education, expertise and experience necessary to competently complete a particular appraisal assignment and (ii) establish and comply with processes and controls reasonably designed to ensure that the AMC conducts its appraisal management services in accordance with applicable appraisal independence standards and regulations.
RESPA
Settlement service providers in connection with the origination or refinance of a federally regulated mortgage loan are subject to RESPA and Regulation X. Under the Dodd-Frank Act, the authority to implement and enforce RESPA was transferred to the CFPB. RESPA authorizes the CFPB, the U.S. Department of Justice, state attorneys general and state insurance commissioners to bring civil enforcement actions, and also provides for criminal penalties and private rights of action.
41

Part I. Item 1. Business
Mortgage insurance, title insurance and other products and services provided by Radian’s affiliates are considered settlement services for purposes of RESPA. The anti-referral fee and anti-kickback provisions of Section 8 of RESPA generally provide, among other things, that settlement service providers are prohibited from paying or accepting anything of value in connection with the referral of a settlement service or sharing in fees for those services. RESPA also prohibits requiring the use of an affiliate for settlement services and requires certain information to be disclosed if an affiliate is used to provide the settlement services. In addition to mortgage insurance, through our homegenius business, we offer an array of services to our customers, including real estate, valuation, hybrid appraisal, title and closing services, many of which are considered settlement services for purposes of RESPA, and therefore, are subject to the anti-referral fee, anti-kickback and required use provisions of RESPA.
In the past, we and other mortgage insurers have faced lawsuits alleging, among other things, that our captive reinsurance arrangements constituted unlawful payments to mortgage lenders under RESPA. We also have been subject to lawsuits alleging that our Pool Mortgage Insurance and contract underwriting services violated RESPA. In addition, we and other mortgage insurers have been subject to inquiries and investigative demands from state and federal governmental agencies, including the CFPB, requesting information relating to captive reinsurance.
In April 2013, we reached a settlement with the CFPB that concluded its investigation with respect to Radian Guaranty without any findings of wrongdoing. As part of the settlement, Radian Guaranty paid a civil penalty and agreed that it would not enter into any new captive reinsurance agreement or reinsure any new loans under any existing captive reinsurance agreement for a period of 10 years ending in 2023. In June 2015, Radian Guaranty executed a Consent Order with the Minnesota Department of Commerce that resolved the Minnesota Department of Commerce’s outstanding inquiries related to captive reinsurance arrangements involving mortgage insurance in Minnesota without any findings of wrongdoing. As part of the Consent Order, Radian Guaranty paid a civil penalty and agreed not to enter into new captive reinsurance arrangements until June 2025. We have not entered into any new captive reinsurance arrangements since 2007. In addition, under the PMIERs, the GSEs prohibit private mortgage insurers from entering into captive insurance arrangements.
Homeowner Assistance Programs
The American Rescue Plan Act of 2021 authorizes approximately $9.9 billion to fund a Homeowner Assistance Fund for “the purpose of preventing homeowner mortgage delinquencies, defaults, foreclosures, loss of utilities or home energy services, and displacements of homeowners experiencing financial hardship after January 21, 2020.” Since the enactment of this legislation, Treasury has issued guidance on this program and announced expected allocations by state, with a statutory minimum requirement of $50 million for each state, the District of Columbia and Puerto Rico. According to the guidance issued by Treasury, eligible use of these funds may include mortgage payment assistance, assistance for housing-related costs related to a period of forbearance, delinquency, or default, facilitating mortgage interest reductions, assistance with insurance payments, including mortgage insurance, utility and tax payments, among others. See “—Housing Finance Reform and the GSEs’ Business Practices—Administrative Reform—COVID-19” above for additional information on efforts to support borrowers impacted by the pandemic.
The SAFE Act
The SAFE Act and its state law equivalents require mortgage loan originators to be licensed with state agencies in the states in which they operate and/or registered with the Nationwide Mortgage Licensing System and Registry (the “Registry”). The Registry is a database established by the Conference of State Bank Supervisors and the American Association of Residential Mortgage Regulators that tracks the licensing and eligibility requirements of loan originators. Among other things, the database was established to support the licensing of mortgage loan originators by each state.
As part of this licensing and registration process, loan originators who are employees of institutions other than depository institutions or certain of their subsidiaries that, in each case, are regulated by a federal banking agency, must generally be licensed under the SAFE Act guidelines enacted by each state in which they engage in loan origination activities and registered with the Registry. Additionally, most states define underwriting and loan processing as a clerical and administrative duty, performed under the supervision of a licensed mortgage loan originator. The entity and its employees that provide our contract underwriting and loan processing services are compliant with the SAFE Act for underwriting in all 50 states and the District of Columbia and compliant for loan processing in 45 states and the District of Columbia.
Mortgage Insurance Cancellation
The HPA imposes certain cancellation and termination requirements for borrower-paid private mortgage insurance with respect to “residential mortgage transactions” as defined in the HPA, and requires certain disclosures to borrowers regarding their rights under the law. Specifically, provided that certain conditions are satisfied, the HPA provides that private mortgage insurance on most loans may be cancelled at the request of the borrower once the principal balance of the mortgage is first scheduled to reach 80% of the home’s original value based on the loan’s initial amortization schedule, or reaches 80% of the home’s original value based on actual payments.
In addition, provided that certain conditions are satisfied, the HPA provides that private mortgage insurance on most loans is subject to servicer-initiated automatic termination once the principal balance of the mortgage is first scheduled to

Part I. Item 1. Business
reach 78% of the home’s original value based on the loan’s initial amortization schedule (or, if the loan is not current on that date, on the date that the loan becomes current). The HPA further provides that private mortgage insurance on most loans is subject to final termination following the date that is the midpoint of the loan’s amortization period (or, if the loan is not current on that date, on the date that the loan becomes current).
The HPA also establishes special rules for the termination of private mortgage insurance in connection with loans that are “high risk.” The HPA does not define “high risk” loans, but leaves that determination to the GSEs for loans up to the GSE conforming loan limits and to lenders for any other loan. For “high risk” loans originated in excess of conforming loan limits, provided that certain conditions are satisfied, the servicer is required to initiate termination once the principal balance of the mortgage is first scheduled to reach 77% of the home’s original value based on the loan’s initial amortization schedule. It is the servicer’s obligation to verify the date when a loan meets all HPA requirements for termination of borrower-paid private mortgage insurance and to promptly instruct the private mortgage insurer to terminate coverage.
Although not provided in the HPA, the GSEs’ guidelines also currently provide that when certain conditions are satisfied, borrowers can request cancellation of borrower-paid mortgage insurance for most loans when the LTV, based upon the current value of the home, is: either 75% or less or 80% or less, depending on the seasoning of the loan and other factors. The GSEs may change these guidelines in the future, including by expanding their mortgage insurance cancellation requirements, which could negatively impact our businesses. In Item 1A. Risk Factors, see “—Changes in the charters, business practices or role of the GSEs in the U.S. housing market generally, could significantly impact our businesses.” and “—Our mortgage insurance business faces intense competition.
The Fair Credit Reporting Act (the “FCRA”)
The FCRA imposes restrictions on the permissible use of credit report information and disclosures that must be made to consumers when information from their credit reports is used. The FCRA has been interpreted by some Federal Trade Commission staff to require mortgage insurance companies to provide “adverse action” notices to consumers in the event an application for mortgage insurance is declined or a higher premium is charged based on the use, wholly or partly, of information contained in the consumer’s credit report.
Privacy and Information Security - Gramm-Leach-Bliley Act of 1999 (the “GLBA”) and Other Regulatory Requirements
As part of our business, we, and certain of our subsidiaries, maintain large amounts of confidential information, including non-public personal information on consumers and our employees. We and our customers are subject to a variety of privacy and information security laws and regulations. The GLBA imposes privacy requirements on financial institutions, including obligations to protect and safeguard consumers’ nonpublic personal information and records, and limitations on the re-use of such information. The GLBA is enforced by state insurance regulators and by federal regulatory agencies.
In addition, many states have enacted privacy and data security laws that impose compliance obligations beyond the GLBA, such as: requiring notification in the event that a security breach results in a reasonable belief that unauthorized persons may have obtained access to consumer nonpublic personal information; imposing additional restrictions on the sale and use of consumers’ personal information; affording consumers new rights of both access and deletion of their personal information; and creating new private rights of action for data breaches. See “—State Regulation—Privacy.”
Federal and state agencies have increased their focus on compliance obligations related to privacy, data security and cybersecurity. The CFPB, Office of the Comptroller of the Currency and non-governmental regulatory agencies, such as the Financial Industry Regulatory Authority (“FINRA”), have announced new compliance measures and enforcement efforts designed to monitor and regulate the protection of personal consumer data, including with respect to: the development and delivery of financial products and services; underwriting; mortgage servicing; credit reporting; digital payment systems; and vendor management. For information regarding the DFS’ cybersecurity regulations and the California Consumer Privacy Act, under “—State Regulation” above, see “—Information Security” and “—Privacy.”
Fair Lending and Fair Servicing
The federal Fair Housing Act, part of the Civil Rights Act of 1968, makes it unlawful for any person whose business includes engaging in residential real estate related transactions to: (i) discriminate in housing-related lending activities against any person on a prohibited basis, or (ii) for any person to discriminate in the sale or rental of housing “or in the provision of services or facilities in connection therewith,” to any person because of a prohibited basis.
