Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Organization | Organization Corporate Office Properties Trust (“COPT”) and subsidiaries (collectively, the “Company,” “we” or “us”) is a fully-integrated and self-managed real estate investment trust (“REIT”) that focuses primarily on serving the specialized requirements of United States Government agencies and defense contractors, most of whom are engaged in defense information technology and national security related activities. We generally acquire, develop, manage and lease office and data center properties concentrated in large office parks located near knowledge-based government demand drivers and/or in targeted markets or submarkets in the Greater Washington, DC/Baltimore region. As of March 31, 2013, our investments in real estate included the following:
• | 210 operating office properties totaling 19.1 million square feet;
• | 10 office properties under construction or redevelopment, or for which we were contractually committed to construct, that we estimate will total approximately 1.3 million square feet upon completion, including one partially operational property included above;
• | land held or under pre-construction totaling 1,703 acres (including 561 controlled but not owned) that we believe are potentially developable into approximately 19.7 million square feet; and
• | a partially operational, wholesale data center which upon completion and stabilization is expected to have a critical load of 18 megawatts.
We conduct almost all of our operations through our operating partnership, Corporate Office Properties, L.P. (the “Operating Partnership”), of which we are the managing general partner. The Operating Partnership owns real estate both directly and through subsidiary partnerships and limited liability companies (“LLCs”). A summary of our Operating Partnership’s forms of ownership and the percentage of those ownership forms owned by COPT as of March 31, 2013 follows:
Common Units | 96 | %
Series H Preferred Units | 100 | %
Series I Preferred Units | 0 | %
Series J Preferred Units | 100 | %
Series K Preferred Units | 100 | %
Series L Preferred Units | 100 | %
Three of our trustees also controlled, either directly or through ownership by other entities or family members, an additional 4% of the Operating Partnership’s common units (“common units”) as of March 31, 2013. In addition to owning real estate, the Operating Partnership also owns subsidiaries that provide real estate services such as property management and construction and development services primarily for our properties but also for third parties.
