Item 7.01 Regulation FD Disclosure

     On May 10, 2007, MGIC Investment Corporation (“MGIC”) and Radian Group Inc. (“Radian”) entered into a First Amendment to Agreement and Plan of Merger (the “First Amendment”). The First Amendment amends the Agreement and Plan of Merger dated as of February 6, 2007 between MGIC and Radian (the “Merger Agreement”) to provide that shares of Radian common stock held by MGIC and its subsidiaries on the closing date of the merger between MGIC and Radian will be converted to MGIC common stock rather than be cancelled. In connection with the amendment, MGIC plans to purchase up to two million shares of Radian common stock from time to time in the open market or in privately negotiated transactions.

     Also on May 10, 2007, MGIC issued a press release announcing that its stockholders had adopted the Merger Agreement at MGIC’s stockholders’ meeting held on May 10, 2007 and containing certain other information. The press release is furnished as Exhibit 99.
