Advisory Bulletins are staff documents through which FHFA provides guidance to the regulated entities regarding particular supervisory issues. Although an Advisory Bulletin does not have the force of a regulation or an order, it does reflect the position of FHFA on the particular issue and is followed by supervisory staff. Advisory Bulletins issued prior to 2004 may include confidential supervisory or financial information and generally are not available to the public. Advisory Bulletins are numbered in sequence by year with the prefix “AB”, e.g., 2004-AB-##. Advisory Bulletins issued prior to July 30, 2008 can be located by clicking on the "FHFB Reading Room" link at the bottom of this page.
