FAM Revisions

The online version supersedes previously issued versions of FAM and can be used immediately to audit federal entity financial statements.

The FAM was revised in June 2018 to reflect significant changes in auditing financial statements in the U.S. government since the last major revisions of FAM Volumes 1 and 2 (GAO-08-585G and GAO-08-586G issued in July 2008) and FAM Volume 3 (GAO-07-313G issued in August 2007). The revisions to the FAM were primarily based on changes in (1) professional auditing and attestation standards of the Auditing Standards Board of the American Institute of Certified Public Accountants, (2) GAO’s Government Auditing Standards (2011), (3) GAO’s Standards for Internal Control in the Federal Government (2014), and (4) the Office of Management and Budget’s audit and reporting guidance.

Volumes 1 and 2 of the FAM have been updated since June 2018 based on further changes to standards and guidance. For example, a revision to GAO’s Government Auditing Standards (GAO-18-568G) was issued in July 2018. These updates were not significant enough to necessitate an exposure draft.

A list of changes is available at the beginning of each volume.

Yellow Book Icon

Government Auditing Standards, also known as the Yellow Book, provide a framework for conducting high quality audits with competence, integrity, objectivity, and independence. Yellow Book establishes requirements for performing financial audits in addition to the requirements contained in the American Institute of Certified Public Accountants standards.

Green Book Icon

Standards for Internal Control in the Federal Government, known as the Green Book, sets standards for federal agencies on the policies and procedures they employ to ensure effective resource use in fulfilling their mission, goals, objectives, and strategic plan. Federal Managers' Financial Integrity Act requires that federal agency executives periodically review and annually report on the agency's internal control systems.
