Audit fee discounting in the post-SOX environment

Purpose This paper aims to investigate whether the expected implementation of Section 404(b) of the Sarbanes-Oxley Act (SOX 404(b)) (the integrated audit requirement) caused auditors to discount their audit fees for non-accelerated filers in anticipation of expected increased future economic rents (DeAngelo, ) from those clients. Design/methodology/approach This paper predicts that auditors charged their non-accelerated filer clients lower audit fees during the years 2005-2007 (in anticipation of increased expected future economic rents from the implementation of the SOX 404(b) requirement) compared with the years 2010-2012 (when it had been determined that non-accelerated filers were permanently exempt from complying with SOX 404(b)). The authors use ordinary least squares regression analysis to examine whether audit fees increased significantly for non-accelerated filers after the permanent exemption announcement. Findings The results show a significant positive association between the exemption announcement and audit fees, supporting the theory that auditors discounted their audit fees for non-accelerated filers in the pre-exemption announcement period. This finding is robust when sensitivity tests are used. Practical implications The findings of audit fee discounting literature related to the post-SOX period are mixed. This study adds to this stream of literature by supporting the notion that audit fee discounting is being practiced post-SOX and is a potential unintended consequence of SOX 404 and the exemption. Thus, investors will be interested in the results of this paper when making their investment decisions with regard to non-accelerated filers. Social implications The results of this paper show that, even in the post-SOX environment, auditors will employ the use of audit fee discounting if a change in regulation incentivizes it. This commentary on the present state of the audit pricing market should be of interest to audit pricing policymakers. Originality/value This paper is one of the first to study audit fee discounting outside the realm of initial audit engagements.
