An Assessment of the Impact of IFRS Adoption on Public Sector Audit Fees and Audit Effort – Some Evidence of the Transition Costs on Changes in Reporting Regimes

Abstract

While many countries have adopted International Financial Reporting Standards (IFRS) for private sector enterprises, New Zealand (NZ), Australia and the United Kingdom adopted IFRS for all sectors, including the public sector. This approach is consistent with the concept of sector‐neutral accounting standards that gained wide acceptance in NZ and Australia in the early 1990s. Although a number of studies have assessed the impact of IFRS adoption in the private sector, and the public sector has provided some evidence as to the effects of IFRS adoption on financial statements, the costs of adopting IFRS have not been examined. One measure of cost is the change in audit fees in an IFRS reporting environment. The authors examine the impact of IFRS adoption in the NZ public sector on audit fees and audit effort. They obtained data regarding audit fees and audit effort in the NZ public sector and compared the pre‐adoption year with the first year of adoption for all segments. Their results indicate a substantial increase in audit fees and audit effort in the first year of IFRS adoption for all segments, with some variation across the segments. Two sectors, local authorities and energy companies, have had significant increases in audit fees and audit effort. These findings provide some empirical evidence regarding the cost of transition to IFRS and are of interest to researchers and regulators in countries that are currently considering transitioning to IFRS or IFRS‐based International Public Sector Accounting Standards standards in reporting for the public sector.
