On November 16, 2011, the SEC's Office of the Chief Accountant (the SEC Staff) published two staff papers. The first summarizes differences between the US GAAP and IFRS frameworks, and the second analyzes how IFRS is applied in practice. The papers were published pursuant to the SEC Staff’s work plan to analyze considerations relevant to the Commission's decision on whether, when, and how IFRS might be incorporated into the US financial reporting system. This Dataline provides a summary of selected differences between US GAAP and IFRS noted in the first paper. It also summarizes the Staff's key observations included in the second paper on how IFRS is applied in practice.
