The International Accounting Standards Board, is a world-wide organization that establishes accounting standards across the board. These standards are packaged as part of the IFRS (International Financial Reporting Standards).
Although the IASB is an international standards board, the accounting standard body in America is GAAP (General Accepted Accounting Principles).
The Board is an independent group of experts with an appropriate mix of recent practical experience in setting accounting standards, in preparing, auditing, or using financial reports, and in accounting education. Broad geographical diversity is also required. The IFRS Foundation Constitution outlines the full criteria for the composition of the Board, and the geographical allocation can be seen on the individual profiles.https://www.ifrs.org/groups/international-accounting-standards-board/
