News Releases

We are disappointed that MGIC filed a lawsuit, which our legal counsel is currently reviewing. The lawsuit claims that Radian has not provided certain information as required by the merger agreement. Since the announcement of the merger, Radian has provided MGIC with significant detailed information.

Since MGIC's August 7, 2007 press release, which stated its management team's preliminary assessment that MGIC is not obligated to complete the merger with Radian, Radian has continued to provide MGIC with responsive information. Radian never consented to the timeline stated in MGIC's August 7, 2007 press release, and is compelled to carefully assess the proprietary nature of the subsequent information requests to ensure that Radian does not provide MGIC with an unfair competitive advantage in the event that MGIC decides that it does not have an obligation to complete the merger.
