We provide mortgage insurance to lenders throughout the United States and to government sponsored entities to protect against loss from defaults on low down payment residential mortgage loans. Primary mortgage insurance provides mortgage default protection on individual loans and covers a percentage of the unpaid loan principal, delinquent interest and certain expenses associated with the default and subsequent foreclosure or sale approved by us, of the underlying property. MGIC Assurance Corporation ("MAC") and MGIC Indemnity Corporation ("MIC"), insurance subsidiaries of MGIC, provide insurance for certain mortgages under Fannie Mae and Freddie Mac (the "GSEs") credit risk transfer programs.</span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Roboto',sans-serif;font-size:9pt;font-weight:400;line-height:120%">Through certain non-insurance subsidiaries, we also provide various services for the mortgage finance industry, such as contract underwriting, analysis of loan originations and portfolios, and mortgage lead generation. </span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Roboto',sans-serif;font-size:9pt;font-weight:400;line-height:120%">At December 31, 2020, our direct primary insurance in force ("IIF") was $246.6 billion, which represents the principal balance in our records of all mortgage loans that we insure, and our direct primary risk in force ("RIF") was $61.8 billion, which represents the IIF multiplied by the insurance coverage percentage. </span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Roboto',sans-serif;font-size:9pt;font-weight:400;line-height:120%">The substantial majority of our NIW has been for loans purchased by the GSEs. The current private mortgage insurer eligibility requirements ("PMIERs") of the GSEs include financial requirements, as well as business, quality control and certain transactional approval requirements. The financial requirements of the PMIERs require a mortgage insurer’s "Available Assets" (generally only the most liquid assets of an insurer) to equal or exceed its "Minimum Required Assets" (which are based on an insurer's book of risk in force, calculated from tables of factors with several risk dimensions). Based on our application of the PMIERs, as of December 31, 2020, MGIC’s Available Assets are in excess of its Minimum Required Assets; and MGIC is in compliance with the PMIERs and eligible to insure loans purchased by the GSEs.</span></div>
