who writes the u.s. standards (u.s. gaap)
Generally Accepted Accounting Principles (United States) 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.[1][2]
