The Reconsideration of IFRS Adoption and Audit Fees: Evidence from UK Private Firms

Abstract

Synopsis The research problem This paper examined whether firms’ decision to switch from the International Financial Reporting Standards (IFRS) to the new Generally Accepted Accounting Practice in the United Kingdom (New UK GAAP) affects their audit fees. Motivation The New UK GAAP was introduced by the UK regulators to enhance the comparability of financial reports and to reduce the high financial reporting costs associated with IFRS. We aimed to provide evidence on whether the reduced frameworks of IFRS, like the New UK GAAP, are a more cost-effective option. Furthermore, only very few studies analyzed the impact of abandoning IFRS on audit fees, and these found inconsistent results using the public firm data. We aimed to extend the current literature by using the private firm data. The test hypotheses Our first set of hypotheses considered whether the switch from IFRS to the New UK GAAP is associated with audit fees. Our second hypothesis tested whether there is a difference in any such association between larger and smaller firms. Target population We focused on the UK private (i.e., nonlisted) firms that have previously voluntarily adopted the IFRS. Adopted methodology We used regression analyses, difference-in-differences (DID) analyses, various matching methods for robustness, and analyses of firms’ financial reports. Analyses Using the UK private (i.e., nonlisted) firm data for the period 2014–2019, we examined the impact of switching from IFRS to the New UK GAAP on audit fees. The data for regression and DID analyses were obtained from the FAME database. We also downloaded the financial reports of two firms from Companies House to analyze the differences in their reports before and after the switch to the New UK GAAP. Findings We found that firms’ decision to switch from IFRS to the New UK GAAP significantly reduced their audit fees, with larger firms experiencing an additional reduction in their audit fees following the switch. Through examining the real examples of firms’ financial reports, we found consistent evidence that firms turning away from IFRS did take advantage of the disclosure exemptions contained within the New UK GAAP, resulting in reduced disclosure, which may explain the reduced audit fees. Overall, our findings suggest that using full IFRS may still be burdensome for the sampled firms that previously voluntarily adopted the IFRS. The findings also imply that an accounting standard consistent with IFRS but requiring less disclosure, such as the New UK GAAP or the IFRS for Small and Medium-sized Entities, may be welcomed by practitioners and represents a useful alternative for standard setters.
