COLUMBIA, Md.--(BUSINESS WIRE)--

Corporate Office Properties Trust (COPT) OFC, an office real estate investment trust (REIT) that focuses primarily on serving the specialized requirements of U.S. Government and Defense Information Technology tenants, announced that during the quarter ended March 31, 2012, it sold seven stabilized properties, two vacant properties and a land parcel for net proceeds of approximately $61 million. The stabilized buildings contained an aggregate of 219,000 square feet and were 80% occupied (63 leases) at the time of sale.

Since announcing its Strategic Reallocation Plan (SRP) in April 2011, COPT has sold a total of $139 million of properties and adjacent land containing approximately 1.2 million of operational square feet, realizing net proceeds of $130.6 million. The properties sold through March 31, 2012 represent 17.8% of COPT's total leases in place at March 31, 2011 (the last reporting period before the SRP was announced), but only 5.4% of consolidated operating square feet at that time.

“We continue to execute on the sale of non-strategic assets with the objective of improving our overall portfolio quality and shedding assets that are more management-intensive, due to their smaller average tenant size. We are also improving our balance sheet flexibility, as we have realized significant net proceeds to date since initiating the SRP, $38 million of which was received in the first quarter from non-revenue generating properties,” stated Roger A. Waesche, Jr., President and Chief Executive Officer of COPT.

During the quarter ended March 31, 2012, COPT also sold its remaining shares of The KEYW Holding Corporation KEYW for approximately $14 million, net of selling costs.
