SL Green Realty Corp., or the Company, is New York City's largest commercial office landlord and is the only fully integrated, self-managed, self-administered Real Estate Investment Trust, or REIT, primarily focused on owning and operating office buildings in Manhattan.
The Company was formed on August 20, 1997 to continue the commercial real estate business of S.L. Green Properties Inc., a company that was founded in 1980 by Stephen L. Green, our current Chairman. For more than 25 years SL Green has been engaged in the business of owning, managing, leasing, acquiring and repositioning office properties in Manhattan. The Company's investment focus is to create value through strategically acquiring, redeveloping and repositioning office properties primarily located in Manhattan, and re-leasing and managing these properties for maximum cash flow.
In 2007, SL Green acquired Reckson Associates Realty Corp. and added over 9 million square feet to its portfolio. Included in this total is over 3 million square feet of Class A office space located in Westchester, New York and Stamford, Connecticut. These suburban portfolios serve as natural extensions of SL Green's core ownership in the Grand Central submarket of Midtown Manhattan. The Company has since made selective additions and dispositions to the holdings in these areas.
