US GAAP vs. IFRS: the basics, March 2010
Earnings per share
Similarities
Entities whose ordinary shares are publicly traded, or that are in the process of issuing such shares in the public markets, must disclose earnings per share (EPS) information pursuant to ASC 260 (formerly FAS 128) and IAS 33 (both entitled Earnings per Share) which are substantially the same. Both require presentation of basic and diluted EPS on the face of the income statement, and both use the treasury stock method for determining the effects of stock options and warrants on the diluted EPS calculation. Both US GAAP and IFRS use similar methods of calculating EPS, although there are a few detailed application differences.
Significant differences
Convergence
The Boards had been jointly working on a short-term convergence project to resolve the differences in the standards, with both Boards issuing exposure drafts in August 2008. In April 2009, the Boards decided to delay the EPS convergence project pending completion of other projects.
