International Financial Reporting Standards, usually called IFRS, are standards issued by the IFRS Foundation and the International Accounting Standards Board (IASB) to provide a common global language for business affairs so that company accounts are understandable and comparable across international boundaries. They are a consequence of growing international shareholding and trade and are particularly important for companies that have dealings in several countries. They are progressively replacing the many different national accounting standards. They are the rules to be followed by accountants to maintain books of accounts which are comparable, understandable, reliable and relevant as per the users internal or external. IFRS, with the exception of IAS 29 Financial Reporting in Hyperinflationary Economies and IFRIC 7 Applying the Restatement Approach under IAS 29, are authorized in terms of the historical cost paradigm. IAS 29 and IFRIC 7 are authorized in terms of the units of constant purchasing power paradigm.
