Real Estate Investment Activity

In May, the New York City Council approved plans for the Company’s One Vanderbilt office tower and demolition has commenced on the site. Located directly west of Grand Central Terminal, the 63-story skyscraper will be 1,501 feet tall and contain 1.6 million rentable square feet of Class A commercial space. One Vanderbilt features open floor plans, efficient use of space, and the highest level of sustainable design in New York City.  TD Bank will anchor approximately 200,000 square feet of space in One Vanderbilt, including a flagship retail store on the northeast corner of 42nd Street and Madison Avenue. The Company will invest an $220.0 million in public infrastructure, constructing new, direct subway access points and circulation areas, easing platform and mezzanine crowding and allowing trains to move more quickly through the station at peak hours.

In May, the Company entered into an agreement to acquire Eleven Madison Avenue for $2.285 billion plus approximately $300.0 million in costs associated with lease stipulated improvements to the property. Eleven Madison Avenue is a 29-story, 2.3 million square foot Class-A, Midtown South office property that was built in 1929 and originally served as the headquarters of Metropolitan Life Insurance Company. After a $700.0 million modernization in the 1990s, it became the North American headquarters of Credit Suisse, which continues to be the largest tenant in the building today. It also will serve as the new headquarters for Sony Corp. of America. The transaction is expected to close in the third quarter of 2015, subject to customary closing conditions.

In July, the Company announced an agreement to sell Tower 45, the office building located at 120 West 45th Street, for $365.0 million, or approximately $830 per square foot.  The 440,000-square-foot Tower 45 was acquired by the Company in 2007 as part of the merger with Reckson Associates. Subsequently, the Company executed a significant capital improvement program that successfully repositioned the property. Tower 45 is currently 96.2 percent leased. The transaction is expected to close in the third quarter of 2015, subject to customary closing conditions.

In July, the Company announced the formation of a joint venture with Invesco Real Estate (“Invesco”) for the ownership of 131-137 Spring Street, a 73,000 square foot mixed-use asset located in SoHo. Under the terms of the agreement, Invesco will acquire an 80.0 percent stake in the property, with the Company retaining a 20.0 percent ownership interest as well as management and leasing responsibilities. The transaction values the property at $277.8 million.  131-137 Spring Street, a six-story building in the heart of the popular SoHo shopping district, features 100 feet of ground floor frontage on Spring Street and houses the multi-level flagship stores for Diesel and Burberry while the balance of the building includes office space and residential rental units.  The transaction is expected to close in the third quarter of 2015, subject to customary closing conditions.

In July, the Company announced an agreement to acquire a 90.0 percent interest in The SoHo Building at 110 Greene Street based on a gross asset valuation of $255.0 million. The 13-story iconic mixed-use property is located in the heart of historic SoHo, one of New York City’s most desirable submarkets. 110 Greene Street is the tallest building in the submarket, offering office and residential tenants unparalleled views, along with large floor plates and substantial common areas.  Retail space at the building, along Greene and Mercer Streets, offers existing and future tenants high visibility on two of the strongest retail streets in Manhattan. Notwithstanding the building’s current prominence, the Company plans additional enhancements to the property as it reintroduces it to the marketplace.  The transaction increases the Company’s sizable footprint in SoHo, adding the submarket’s best office space to the Company’s commercial portfolio, and extending its substantial retail presence. The transaction is expected to close in the third quarter of 2015, subject to customary closing conditions.

In July, the Company announced an agreement to acquire two mixed-use properties located at 187 Broadway and 5-7 Dey Street for $63.7 million.  Located adjacent to the entrance to Downtown Manhattan’s new Fulton Transit Center and one block east of the World Trade Center, the site consists of two mixed-use, retail/office buildings in a neighborhood that has undergone rapid growth in the office, residential and retail segments. The transaction is expected to close in the third quarter of 2015, subject to customary closing conditions.

In June 2015, the Company closed on the off-market acquisition of a mixed-use residential and retail property located on the Upper East Side of Manhattan for $50.0 million.
