Concentration of Revenue | Concentration of Revenue A large concentration of our revenue from real estate operations was earned from our largest tenant, the United States Government, including 20% of our rental revenue in 2015, 18% in 2014 and 18% in 2013 (continuing and discontinued operations, and excluding tenant recoveries and other real estate operations revenue). Our rental revenue from the United States Government was earned primarily from properties in the Fort Meade/Baltimore Washington Corridor, Lackland Air Force Base, Navy Support Locations and Redstone Arsenal business subsegments (see Note 17). No other individual tenants accounted for 10% or more of our revenue from real estate operations. In addition, we also derived in excess of 90% of our construction contract revenue from the United States Government in each of the years set forth on the consolidated statements of operations. In addition, we derived large concentrations of our revenue from real estate operations from certain business segments as set forth in Note 17.
