The effect of non-audit fees and industry specialization on the prevalence and accuracy of auditor’s going-concern reporting decisions

Journal of International Accounting, Auditing and Taxation

Marshall A. Geiger a, Ilias G. Basioudis b, Paul DeLange c


The issue of auditors impairing their independence when providing non-audit services (NAS) to audit clients continues to be subject of global regulatory concern. However, the profession has long argued that knowledge gained from providing NAS can spill over to other areas and can serve to improve audit quality. Accordingly, we revisit the effect that NAS have on the likelihood of an auditor issuing a going concern modified opinion (GCMO) to distressed clients, as well as the accuracy of those opinions. We also examine whether industry specialization is associated with GCMO decisions and their accuracy.

Editorial: Special issue on the future of audit—A collection of personal reflections

International Journal of Auditing

Ilias G. Basioudis


Does the audit have a future? Well, it depends. In recent months, the UK Government has been attempting to dig deeply and make significant changes to the audit service provided by accounting firms. On the other hand, the future of audit has been discussed many times in the last 50+ years, and there have not been many noteworthy adjustments in the audit as we all know it; the main objective(s) of the audit has not been modified much since the mid of the 19th century.

Effects of the Big 4 national and city-level industry expertise on audit quality in the United Kingdom

Journal of International Accounting, Auditing and Taxation

Khairul Ayuni Mohd Kharuddin a, Ilias G Basioudis b, Omar Al Farooque c


In this study, we examine for the first time in the UK, the effects of the Big 4 audit firms’ national (firm-level) and city-office (office-level) industry specialisation on audit quality. Based on public firms listed on the London Stock Exchange (LSE), we find that clients of the Big 4 joint national and city-level auditor industry specialists have smaller magnitude of discretionary accruals, lower income-increasing discretionary accruals, and lesser accrual estimation error, indicating higher audit quality. In addition, we also find that when the Big 4 auditors are both national and city-specific industry leaders, their clients are more likely to be issued a modified audit opinion as well as a going concern audit report. The findings imply that industry expertise of the national and city-based professionals of the Big 4 firms have now been captured and distributed more broadly throughout the firm and within their offices. Moreover, the outcome of this study provides additional evidence that the more recent UK evidence of a fee premium exclusively attached to the Big 4 joint specialists reflects their differentiated service and higher quality audit relative to their non-specialist counterparts.

Partner industry specialization and audit pricing in the United Kingdom

Journal of International Accounting, Auditing and Taxation

2019 This study investigates the effects of audit partner industry specialization on audit pricing in the UK market. The mandatory disclosure of the name of the engagement partner in the auditor reports of UK public listed companies took effect from April 2008. Given that the identity of the audit partner is now observable to users of financial statements, it can be argued that there may be an incentive for partner-level differentiation in auditing products, and hence, audit quality. This research examines whether auditor industry expertise in the UK is driven by firm, office, or partner level expertise. The fee premium observed in the study is a joint product of firm and partner level of industry expertise with the highest premium occurring when the client is also audited by an industry leading partner. This finding lends support to the argument that industry expertise is uniquely attributable to the individual audit partner’s human capital in terms of their knowledge and experience from leading audit engagements in a particular industry. It also provides evidence that some fee premiums earned by audit firms and documented in prior literature are most probably the product of the individual audit partner’s expertise.
