Audit Fees for Initial Audit Engagements Before and After SOX

Abstract

SUMMARY: Legislators, regulators, and the media have expressed concerns that auditors “lowball” the fees for initial-year audits and that such fee discounts can lead to reduced audit quality. We hypothesize that initial-year audit fee discounts will be less likely in the post-SOX period than in the pre-SOX period. Using both fee-levels and fee-changes models, we find that Big 4 clients receive initial-year audit fee discounts of about 24 percent in 2001; this finding is consistent with results from many prior studies that have examined various periods prior to SOX. However, we find that in 2005–2006 Big 4 clients pay an initial-year audit fee premium of around 16 percent. We also document that the Big 4 are much less likely to serve as a successor, following an auditor change, in 2005–2006 than in 2001. Overall, the findings suggest that concerns about initial-year audit fee discounts are not supported by empirical evidence in the post-SOX period. The results also suggest that the Big 4 have become more conservative in the post-SOX period with respect to client acceptance and pricing decisions.
