The association between abnormal audit fees and audit quality after IFRS adoption : Evidence from Korea

Purpose This paper aims to examine how the relationship between abnormal audit fees and audit quality changed after adoption of the International Financial Reporting Standards (IFRS) in Korea. Design/methodology/approach Using empirical data collected over the period from 2008 to 2013, this study analyzes the association between abnormally high/low audit fee and audit quality. This study uses linear regression to test the hypothetical relation using discretionary accrual as a proxy for audit quality. Findings This study finds that there exists no significant relationship between abnormally high audit fees and audit quality measured by the magnitude of discretionary accruals in the pre-IFRS adoption period. However, the relationship between abnormally high audit fees and the magnitude of discretionary accruals turns to be positive in the post-IFRS adoption period. These finding suggests that the IFRS enables some clients to engage more discretion in the choice of discretionary accruals and auditors charge higher audit fees in return for allowing the discretion for such clients. Practical implications This study provides insight to regulators of the need to review carefully the financial statements of firms with abnormally high audit fees, and to investors to be more cautious when using financial information about these firms. Originality/value To the best of authors’ knowledge, this is the first study to assess IFRS impact on audit fee-quality relation. Also, unique Korean audit market with intensifying competition and discounting audit fee provides interesting setting to review the impact of abnormal audit fee on audit quality.
