Client industry characteristics and auditor changes

Abstract

Purpose

This study aims to examine whether the industry characteristics of homogeneity, product competition, high auditor competition and accounting standards complexity are associated with auditor changes.

Design/methodology/approach

Logistic regressions test for significance of the industry characteristics on resignations, dismissals and directional changes to and from Big 4 and nonBig 4 auditors after controlling for client, auditor and engagement factors.

Findings

The authors report a lower likelihood of auditor resignations with greater accounting standards complexity. The authors also report a greater likelihood of auditor dismissals with greater industry homogeneity, greater product competition and greater auditor competition. Results also show that accounting standards complexity is associated with a lower likelihood of changes from Big to nonBig auditors, and industry homogeneity is associated with a greater likelihood of changes from Big to nonBig. Also, greater auditor competition is associated with a lower likelihood of changes from nonBig to Big auditors.

Research limitations/implications

Prior research has established the importance of industry characteristics to the market for audit services (Cairney and Stewart, 2015; Wang and Chui, 2015; Cahan et al., 2011; Bills et al., 2015). The authors report that industry characteristics also impact auditor changes. Second, previous research has used various methods that indicate general industry effects on changes. The paper contributes to this research by specifying industry characteristics. Limitations include the reliance on the self-reporting in 8-Ks to identify auditors resigning and firms dismissing auditors. Also, the paper relies on proxies for industry characteristics that were developed in prior research.

Practical implications

Regulators have expressed concern over the relatively low rates of auditor changes and the problem of lack of auditor choice. By demonstrating a significant effect of industry characteristics on changes, the authors indicate some levers that may be available to influence rates of auditor changes, especially realignments to nonBig.

Originality/value

This is one of the first studies to examine how specific industry characteristics impact auditor changes. The study may be of interest to academics who are interested in how industry factors influence auditor changes. It may also interest policymakers who could lever the characteristics of industries to address concerns about the low rates of auditor changes.
