The International Financial Reporting System, or IFRS, is a set of global accounting standards used by over 125 jurisdictions worldwide. The standards are developed under the authority of the International Accounting Standards Board. You can read about the composition of the Board and get detailed information on the activities of the IASB by visiting the IFRS website.

The Financial Accounting Standards Board (FASB) is responsible for the U.S. GAAP (generally accepted accounting principles), while the International Accounting Standards Board (IASB) issues the International Financial Reporting Standards (IFRS). Over the years, there has been discussion of moving GAAP closer to IFRS with the eventual goal of having a single set of standards. There does not currently appear to be any indication that this is going to happen. The U.S. Securities and Exchange Commission (SEC) is also involved in the discussion.
