Reviewing IFRS Goodwill Accounting Research: Implementation Effects and Cross-Country Differences

We review 42 studies from 2008 to early 2017 about IFRS goodwill accounting choices for recognition, impairment, and disclosure of goodwill, focusing on cross-country evidence of implementation effects. We develop a model of application of goodwill accounting based on IFRS 3, IAS 36, and country- and firm-level influences to analyze the research and to summarize existing evidence about goodwill accounting choices. We report evidence in support of IFRS accounting for goodwill recognition, impairment, and disclosure from many countries. However, evidence regarding value relevance is mixed. Overall, there is a lack of cross-country evidence regarding factors affecting goodwill accounting. Many studies show goodwill recognition, impairment, and disclosure are associated with economic and firm factors, and there is some evidence about the impact of managerial incentives and a lack of timeliness in impairment recognition. There is scope for more cross-country studies showing how institutional factors affect the application of IFRS 3 and IAS 36.
