We actively manage Radian Guaranty’s capital position in various ways, including: (1) through internal and external reinsurance arrangements; (2) by seeking opportunities to reduce our risk exposure through commutations or other negotiated transactions; (3) by contributing additional capital from Radian Group to our mortgage insurance subsidiaries; and (4) by realizing gains in our investment portfolio through open market sales of securities. Radian Group had unrestricted cash and liquid investments of $375.6 million as of December 31, 2012, which amount includes approximately $38.7 million of future expected corporate expenses and interest payments that have been accrued for and paid by certain subsidiaries to Radian Group as of that date. Radian Group currently has $79.4 million of outstanding debt due in February 2013, $54.8 million of outstanding debt due in 2015, $195.2 million of outstanding debt due in June 2017 and an additional $450 million of convertible debt due in November 2017. We intend to maintain Radian Guaranty’s risk to capital below 25:1 throughout 2013, including, if necessary by making contributions to Radian Guaranty from Radian Group’s remaining available liquidity. Depending on the extent of our future statutory incurred losses in our mortgage insurance subsidiaries and in Radian Asset Assurance, as well as the level of new insurance written and other factors, the amount of capital contributions required for Radian Guaranty to remain in compliance with the Statutory RBC Requirements could be substantial and could exceed amounts available at Radian Group.
Our ability to continue to reduce Radian Guaranty’s risk through affiliated reinsurance arrangements may be limited. These arrangements are subject to regulation by state insurance regulators who could decide to limit, or require the termination of, such arrangements. In addition, certain of these affiliated reinsurance companies currently are operating at or near minimum capital levels and have required, and may continue to require, additional capital contributions from Radian Group in the future. One of these affiliated insurance companies, which provides reinsurance to Radian Guaranty for coverage in excess of 25% of certain loans insured by Radian Guaranty, is a sister company of Radian Guaranty, and therefore, any contributions to this insurer would not be consolidated with Radian Guaranty’s capital for purposes of calculating Radian Guaranty’s risk-to-capital position. In addition, we must obtain prior approval from one or both of the GSEs to enter into new, or to modify existing, reinsurance arrangements. If we are limited in, or prohibited from, using reinsurance arrangements to reduce Radian Guaranty’s risk, it would adversely affect Radian Guaranty’s risk-to-capital position.
