The International Accounting Standards Board (IASB) and Financial Accounting Standards Board (FASB) set accounting standards for financial reporting, aiming to improve transparency, reliability, and understanding. The IFRSs developed by IASB include 57 accounting standards, while FASB's GAAP guidelines are used internationally. Accounting standards can be classified into disclosure, presentation, and content standards. The benefits of accounting standards include improved reliability and credibility of financial statements, beneficial for accountants and auditors, facilitates comparison and conflict resolution, and helps with regulatory compliance. However, limitations include restrictions on companies' choices, inability to override statue, and potential controversies.
