The effect of auditor change on initial audit fee discount and non-audit services

Abstract

The purpose of this research is to verify whether non-audit services are provided without additional fees at the initial audit as a strategy to win an external audit contract, which could give the appearance of initial audit fee discount. From the results, non-audit services are provided at the initial audit, and the initial audit fee is discounted accordingly, only when the independent auditor is changed from a Big 4 accounting firm to a non-Big 4 accounting firm. However, there is no meaningful relevance in any other types of changes. Therefore, if the auditor is changed from a Big 4 accounting firm to a non-Big 4 accounting firm, non-audit services are provided without additional fees in order to win an external audit contract, and the publication of audit fees with a division between the audit service fee and the non-audit service fee may give the appearance of a discounted audit service fee.
