AmBase Corporation (the “Company”) is a holding company which, through a wholly owned subsidiary, owns a commercial office building in Greenwich, Connecticut. The Company previously owned an insurance company and a savings bank.

In February 1991, the Company sold its ownership interest in The Home Insurance Company and its subsidiaries. On December 4, 1992, Carteret Savings Bank, FA (“Carteret”) was placed in receivership by the Office of Thrift Supervision (“OTS”).

The Company currently earns non-operating revenue consisting principally of investment earnings on investment securities and cash equivalents. The Company continues to evaluate a number of possible acquisitions, and is engaged in the management of its assets and liabilities, including the contingent assets associated with its legal claims, as described in Notes 9 and 10.  Discussions and negotiations are ongoing with respect to certain of these matters. From time to time, the Company and its subsidiaries may be named as a defendant in various lawsuits or proceedings. The Company intends to aggressively contest all litigation and contingencies, as well as pursue all sources for contributions to settlements.
