Thomas Properties Group, Inc. (NASDAQ: TPGI) announced today that its affiliate, TPG/CalSTRS, LLC, has completed the sale of the 578,284 square foot property known as 2500 CityWest Boulevard in Houston, Texas, together with two adjacent raw land parcels totaling 6.3 acres. TPGI’s share of the net proceeds from the sale is approximately $16 million after closing costs and repayment of mortgage debt. “The closing of this transaction represents another significant step in executing our strategic plan, which includes pruning our portfolio of certain joint venture investments that have been repositioned and stabilized, and reducing our land holdings,” stated Jim Thomas, Chairman and CEO. “2500 CityWest is a property that we have successfully repositioned and stabilized. We are pursuing a number of attractive opportunities for the investment of these sales proceeds. We remain committed to Houston as a long-term strategic investment market based on its compelling economic and job growth drivers.” About Thomas Properties Group, Inc.
