Adoption would mean that the SEC sets a specific timetable when publicly listed companies would be required to use IFRS as issued by the IASB. Convergence means that the U.S. Financial Accounting Standards Board (FASB) and the IASB would continue working together to develop high quality, compatible accounting standards over time. More convergence will make adoption easier and less costly and may even make adoption of IFRS unnecessary. Supporters of adoption, however, believe that convergence alone will never eliminate all of the differences between the two sets of standards. In 2011, SEC staff introduced a possible method of incorporating IFRS into the U.S. financial reporting system that would represent an endorsement and convergence approach for aligning U.S. GAAP with IFRS over a period of time. Ultimately, the expectation is that the SEC will make a determination on whether it will incorporate IFRS into the financial reporting system for U.S. issuers and, if it decides to incorporate IFRS, the method of incorporation.
