Foursquare Capital (FSQR) is a new AllianceBernstein-backed REIT that plans to invest in mortgage-backed assets. Expect an IPO at some point next week.

According to the Wall Street Journal the company "joins the CMBS fray as the U.S. government steps in to lure buyers for the securities by taking on much of the risk associated with them. Values of them have tumbled the past year as that market turned south, with real-estate values slumping and occupancy rates falling."
