Similarities
The guidance in ASC 805 Business Combinations (formerly FAS 141(R)) and IFRS 3(R) (both entitled Business Combinations) represents the culmination of the first major collaborative convergence project between the IASB and the FASB.
Pursuant to ASC 805 and IFRS 3(R), all business combinations are accounted for using the acquisition method. Under the acquisition method, upon obtaining control of another entity, the underlying transaction should be measured at fair value, and this should be the basis on which the assets, liabilities and noncontrolling interests of the acquired entity are measured (as described in the table below, IFRS 3(R) provides an alternative to measuring noncontrolling interest at fair value), with limited exceptions. Even though the new standards are substantially converged, certain differences still exist.
The revised standards are effective for business combinations for which the acquisition date is on or after the beginning of the first annual reporting period beginning on or after 15 December 2008 and 1 July 2009 for companies applying US GAAP and IFRS, respectively. Unlike ASC 805, early adoption of IFRS 3(R) is permitted if certain criteria are met.
Significant differences
Other differences may arise due to different accounting requirements of other existing US GAAP-IFRS literature (for example, identifying the acquirer, definition of control, definition of fair value, replacement of share-based payment awards, initial classification and subsequent measurement of contingent consideration, initial recognition and measurement of income taxes, and initial recognition and measurement of employee benefits).
Convergence
No further convergence is planned at this time.
