Businesses that file financial statements according to International Financial Reporting Standards have been warned to study carefully how recent changes to merger accounting under IFRS might affect them.

The International Accounting Standards Board recently finished revisions to its standards for mergers and acquisitions as part of a joint project with the U.S. Financial Accounting Standards Board to harmonize merger accounting on both sides of the Atlantic. FASB unveiled its amended rules in December; IASB did the same earlier this month.
