ORGANIZATION OF THE PARENT COMPANY AND THE OPERATING PARTNERSHIP | 1. ORGANIZATION OF THE PARENT COMPANY AND THE OPERATING PARTNERSHIP The Parent Company is a self-administered and self-managed real estate investment trust (“REIT”) that provides leasing, property management, development, redevelopment, acquisition and other tenant-related services for a portfolio of office, retail and mixed-use properties. The Parent Company owns its assets and conducts its operations through the Operating Partnership and subsidiaries of the Operating Partnership. The Parent Company is the sole general partner of the Operating Partnership and, as of December 31, 2016, owned a 99.1% interest in the Operating Partnership. The Parent Company’s common shares of beneficial interest are publicly traded on the New York Stock Exchange under the ticker symbol “BDN”. As of December 31, 2016, the Company owned 113 properties that contain an aggregate of approximately 17.6 million net rentable square feet and consist of 93 office properties, seven mixed-use properties, one retail property (101 properties, collectively the “Core Properties”), four development properties, three redevelopment properties and five properties classified as held for sale (collectively, the “Properties”). In addition, as of December 31, 2016, the Company owned economic interests in 14 unconsolidated real estate ventures (collectively, the “Real Estate Ventures”), seven of which own properties that contain approximately 8.0 million net rentable square feet of office space; two of which own 4.3 acres of undeveloped parcels of land; two of which own 1.4 acres of land under active development; two of which own residential towers that contain 345 and 321 apartment units, respectively, and one of which owns an apartment complex that contains 398 units.
