Triad Guaranty Inc., operating through its subsidiary Triad Guaranty Insurance Corporation, is presently in the process of winding down its mortgage guaranty insurance business. This "run-off" status is a direct consequence of two corrective mandates issued by the Illinois Department of Insurance. The company, which was established in 1987, maintains its principal office in Birmingham, Alabama. Additionally, on June 3, 2013, Triad Guaranty Inc. voluntarily sought reorganization under Chapter 11, filing its petition with the U.S. Bankruptcy Court for the District of Delaware.
