CEO image, NAS and risk assessment

Abstract

Purpose

The purpose of this paper is to examine the interactive effect of the provision of non‐audit services (NAS) and auditors' perceptions of management integrity on assessments of risk of material misstatement.

Design/methodology/approach

The research method consisted of a behavioral experiment involving 47 audit seniors from a big‐four accounting firm.

Findings

Manipulations of management integrity significantly affected risk assessments. Manipulations of NAS did not affect risk assessment. However, a significant interaction manifested itself – participants who role‐played auditors providing significant tax consulting services tended to highly discount the incremental risk of material misstatement arising out of dubious management integrity, compared with their counterparts who role‐played auditors not providing any NAS.

Research limitations/implications

This study shows that, while provision of NAS may not in and of itself impact auditor independence, it has the potential to impact audit quality by mitigating the effect of other audit evidence. This study also highlights the importance of testing for interactions since main effects may not readily capture the complexities involved.

Practical implications

The finding calls for continuing attention to the issue of NAS provision and audit firm culture and a redoubling of efforts to ameliorate the effects of auditor‐provided NAS.

Originality/value

This is one of the few papers that consider the interactive effect of provision of NAS and CEO image on assessment of management integrity. This is important because the likelihood of fraud increases when management integrity is suspect and the auditor is not vigilant.
