The Federal Housing Finance Agency may be close to picking a chairman to head the common securitization platform project, which still does not have a chief executive officer, according to one source briefed on the matter. This official, who requested his name not be used, said there are two prospects for the chairman slot, “but FHFA still hasn’t decided on one.” The CSP, formally known as Common Securitization Solutions LLC, is a joint venture equally owned by Fannie Mae and Freddie Mac. CSS recently signed a lease on office space in Bethesda, MD, just outside the District of Columbia.
