This paper investigates the application of the product differentiation and shared efficiency approaches to understand the impact of the auditor industry specialisation (IS) on audit fees in relation to Fair Value Disclosures (FVD).
The study uses 1,470 firm-year observations for the period 2005–2018 and is focused on Jordanian financial firms. Two competing theoretical approaches of IS proxied by audit fee-based measures were employed: firstly, the product differentiation approach measured using Market Share-based (MS) measure and secondly, the shared efficiency approach measured using Portfolio Share-based (PS) measure. The paper employs the Ordinary Least Squares regression to test the association between the proportion of fair-valued assets (using fair value hierarchy inputs) and audit fees.
The results suggest that the association between the proportion of fair-valued assets and audit fees is strengthened (weakened) when the client hires specialist auditors identified by MS (PS). This association varied across the fair value inputs. Level 1 assets were found to be only moderated by both scenarios positively (negatively) for MS (PS) experts. The results are robust after controlling the endogeneity of auditor self-selection.
The results provide valuable insights for policymakers into challenges of auditing FVD. These insights present a valuable input for the development of FVD policies and practices as well as providing guidance for updating auditor prices. Additionally, the results provide a foundation for policymakers and regulators to introduce and update fair value auditing practices. The current findings are generalisable to other countries, including the Middle East and North Africa, and are particularly beneficial for those countries which have adopted the fair value model.
This study contributes to the theory by demonstrating the impact of the auditor industry expertise on post-implementation costs of FVD. The novelty of the study lies in introducing principle-based standards requirements of FVD to test the relationship. This approach is based on the IFRS disclosure requirements using data from the Jordanian financial sector to examine this relationship.
