The Federal Housing Finance Agency (FHFA) is issuing a final regulation that will govern the portfolio holdings of Fannie Mae and Freddie Mac (collectively, the Enterprises) during the pendency of the conservatorships. The final regulation adopts FHFA's interim final rule on portfolio holdings, without change. See 74 FR 5609, January 30, 2009. That interim rule adopted the portfolio limits specified in each Enterprise's Senior Preferred Stock Purchase Agreement (PSPA) with the Department of the Treasury (Treasury) as the regulation limits. Specifically, it provides that each Enterprise comply with the portfolio limits contained in the respective PSPAs, as they may be amended from time to time. The interim regulation also stipulated that the regulation is to be in effect until amended or the Enterprises are no longer subject to the PSPAs.
