IFRS stands for International Financial Reporting Standards, which is a set of international accounting standards stating how transactions and events should be reported in financial statements. India has adopted the "all at once approach" to convergence where Indian Accounting Standards will fully converge with IFRS over time. There are multiple IFRS covering various accounting topics from business combinations to financial instruments. India's convergence phases will require the largest companies to adopt IFRS-converged financial statements beginning in 2011 based on their net worth, with smaller companies transitioning in later phases by 2013-2014.
