Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Organization | Organization COPT Defense Properties (“COPT Defense”) and subsidiaries (collectively, the “Company”, “we” or “us”) is a fully-integrated and self-managed real estate investment trust (“REIT”) focused on owning, operating and developing properties in locations proximate to, or sometimes containing, key U.S. Government (“USG”) defense installations and missions (which we refer to herein as our Defense/IT Portfolio). Our tenants include the USG and their defense contractors, who are primarily engaged in priority national security activities, and who generally require mission-critical and high security property enhancements. In September 2023, we changed our name from Corporate Office Properties Trust to COPT Defense Properties to better describe our investment strategy’s focus on locations serving our country’s priority defense activities. As of December 31, 2023, our Defense/IT Portfolio included (all references to number of properties, square footage and acres are unaudited): >190 operating properties totaling 21.7 million square feet comprised of 16.0 million square feet in 160 office properties and 5.7 million square feet in 30 single-tenant data center shells. We owned 24 of these data center shells through unconsolidated real estate joint ventures; >five properties under development (two office properties and three data center shells) that will total approximately 817,000 square feet upon completion; and >approximately 660 acres of land controlled that we believe could be developed into approximately 7.9 million square feet. We also owned eight other operating properties totaling 2.1 million square feet and approximately 50 acres of other developable land in the Greater Washington, DC/Baltimore region as of December 31, 2023. We conduct almost all of our operations and own almost all of our assets through our operating partnership, COPT Defense Properties, L.P. (“CDPLP”) and subsidiaries (collectively, the “Operating Partnership”), of which COPT Defense is the sole general partner. CDPLP owns real estate directly and through subsidiary partnerships and limited liability companies (“LLCs”). In addition to owning real estate, CDPLP also owns subsidiaries that provide real estate services such as property management, development and construction services primarily for our properties but also for third parties. Some of these services are performed by a taxable REIT subsidiary (“TRS”). In September 2023, we changed CDPLP’s name from Corporate Office Properties, L.P. to COPT Defense Properties, L.P. Equity interests in CDPLP are in the form of common and preferred units. As of December 31, 2023, COPT Defense owned 97.8% of the outstanding CDPLP common units (“common units”) and there were no preferred units outstanding. Common units not owned by COPT Defense carry certain redemption rights. The number of common units owned by COPT Defense is equivalent to the number of outstanding common shares of beneficial interest (“common shares”) of COPT Defense, and the entitlement of common units to quarterly distributions and payments in liquidation is substantially the same as that of COPT Defense common shareholders. In September 2023, the ticker symbol under which our common shares are publicly traded on the New York Stock Exchange (“NYSE”) changed from “OFC” to “CDP”.
