Generally Accepted Accounting Principles, also called GAAP or US GAAP, is the accounting standard adopted by the U.S. Securities and Exchange Commission (SEC). While the SEC has stated that it intends to move from US GAAP to the International Financial Reporting Standards (IFRS), the latter differ considerably from GAAP and progress has been slow and uncertain.
The Financial Accounting Standards Board (FASB) has published US GAAP in Extensible Business Reporting Language (XBRL) beginning in 2008.
Auditors took the leading role in developing GAAP for business enterprises.
Accounting standards have historically been set by the American Institute of Certified Public Accountants (AICPA) subject to Securities and Exchange Commission regulations. The AICPA first created the Committee on Accounting Procedure in 1939 and replaced that with the Accounting Principles Board in 1959. In 1973, the Accounting Principles Board was replaced by the Financial Accounting Standards Board (FASB) under the supervision of the Financial Accounting Foundation with the Financial Accounting Standards Advisory Council serving to advise and provide input on the accounting standards. Other organizations involved in determining United States accounting standards include the Governmental Accounting Standards Board (GASB), formed in 1984; and the Federal Accounting Standards Advisory Board (FASAB), formed in 1990.
