(the “Company” or “Simon Property”) (NYSE:SPG) is a self-administered and self-managed real estate investment trust (“REIT”). Simon Property Group, L.P. (the “Operating Partnership”) is a subsidiary partnership of the Company. The Company and the Operating Partnership (collectively, “Simon Group”) are engaged primarily in the ownership, development and management of retail real estate properties, primarily regional malls, Premium Outlet Centers® and community/lifestyle centers. At March 31, 2007, the Company owned or had an interest in 285 properties in the United States containing an aggregate of 201 million square feet of gross leasable area (GLA) in 38 states plus Puerto Rico. The Company also holds interests in 53 European shopping centers in France, Italy and Poland; 5 Premium Outlet Centers in Japan; and one Premium Outlet Center in Mexico.
