As of December 31, 2012, its principal mortgage insurance subsidiaries, Mortgage Guaranty Insurance Corporation (MGIC) and MGIC Indemnity Corporation (MIC), were each licensed in all 50 states of the United States, the District of Columbia and Puerto Rico. During the year ending December 31, 2012, the Company wrote new insurance in each of those jurisdictions in MGIC and/or MIC. The Company capitalized MIC to write new insurance in certain jurisdictions where MGIC no longer meets, and is unable to obtain a waiver of, those jurisdictions' minimum capital requirements. Private mortgage insurance covers losses from homeowner defaults on residential mortgage loans, reducing and, in some instances, eliminating the loss to the insured institution if the homeowner defaults.
