The CEO and chairman of RXR is Scott Rechler, who also was the CEO and chairman of Reckson.

RXR has more than $6 billion in assets under management. Some of its biggest building purchases include 601 West 26th Street (Starrett Lehigh) for $920 million and 237 Park Avenue (Park Avenue Atrium) for $800.1 million. In 2010, RXR acquired 1330 Avenue of the Americas, a 525,825-square-foot office building in Midtown Manhattan, from well-known developer Harry B. Macklowe. Other RXR Realty assets include 75 Rockefeller Plaza, on which RXR has begun a complete renovation, and 340 Madison Avenue.
