NEW YORK CITY-It’s been a busy few weeks for SL Green Realty Corp. The company, along with joint venture partner JP Morgan, has reached an agreement to sell One Court Square, the 1.4-million-square-foot office tower in Long Island City fully leased to Citibank, N.A. And in Lower Manhattan, the company has formed a joint venture with the Moinian Group to recap 180 Maiden Lane—providing SL Green with a 49.9% interest in the 1.1-million-square-foot property.

One Court Square will be bought by a private investor group for roughly $340 per square foot. According to Real Capital Analytics, the group includes Joel Schreiber, the owner of Waterbridge Capital and David Werner. It’s anticipated that the transaction, which includes $315 million of existing debt, will net SL Green $42.8 million.

Further strengthening the company’s coffers is a new $1.5-billon unsecured line of credit that it has closed, refinancing a $1.5-billion credit facility that was due to expire in June 2012. The new line of credit matures in November 2016 and bears interest at 150 basis points over LIBOR. According to James Mead, SL Green’s CFO, it “was strongly oversubscribed by a collection of some of the world’s most liquid and highest quality financial institutions.” Mead went on to say in a prepared statement that the new line of credit would allow SL Green to “now move forward to pursue future growth opportunities with a credit facility that is greatly simplified.”

In Lower Manhattan, the 180 Maiden Lane property—a fully leased, 41-story office tower in the Financial District—was recapped in a deal that values it at $390 per square foot. For SL Green, New York’s largest office landlord, the move signals a continued broadening of the company’s scope in Manhattan as it focuses attention on the Downtown market as well as its bread and butter Midtown properties. CEO Marc Holliday said as much in a prepared statement about the deal, pointing to the revitalization of the area.

“This former 9-to-5 area has become a magnet for the city’s economic growth,” Holliday said. “With the growing number of companies and their employees who want to be in the downtown market, SL Green saw an opportunity to become a more substantial local presence by acquiring one of the highest quality assets in the area.”
