Interstate General Company L.P. (IGC) was formed as a Delaware limited partnership in 1986. IGC and its predecessors have been engaged in diversified real estate development, large scale community development, investment properties and income producing properties for over forty years.

IGC’s principal real estate assets were spun off in 1998 to a new public company called American Community Properties Trust. IGC retained some real estate assets for the purpose of funding the startup and success of its affiliated companies in the waste to energy business. These two related companies are Interstate Waste Technologies (IWT) and Caribe Waste Technologies, Inc. (CWT), collectively referred to as IWT/CWT. IWT is a Delaware corporation. CWT is a Puerto Rico corporation. IGC unitholder's interest in these two companies was held in trust until December, 2006.

IGC formerly traded on the American and Pacific Stock Exchanges. IGC was de-listed from both exchanges in December, 2004.

IGC announced in a Unitholder Report dated January 18, 2006
that its Board and management concluded that it was in the unitholder's best interest to recapitalize IWT/CWT and terminate the IGC partnership. Effective January 1, 2006, IGC contributed certain assets and liabilities to IWT and the IGC partnership terminated operations. The purpose was to strengthen IWT/CWT's financial qualifications to enable it to better compete for existing and new projects as well as to reduce the administrative costs of IGC. Please refer to the Unitholder Report.

The IGC partnership was formally disolved in Delaware December, 2007.
