The authors look at 1,317 mandatory adopters (38% from non-EU countries) from 26
countries (eight non-EU). They compare these with a sample of non-IFRS adopters for the
period 2001-2006. They find that accounting comparability increases for both groups after
IFRS adoption, but more for non-adopters. They comment that ‘this finding suggests the
imposition of IFRS did little to increase accounting comparability relative to the worldwide
trend’.
