Auditor practices and auditee responses to corporate governance audit regulation in Nigeria

Purpose - The purpose of this study is to examine both the responses of auditees to corporate governance audit (CGA) regulation and the practices of CGA auditors. Design/methodology/approach - The study used a mixed method. Content analysis of 200 annual and CGA reports was carried out for 13 years, from 2008 to 2021, split into voluntary disclosure and mandatory disclosure periods. Quantitative analysis was also conducted using Kruskal–Wallis and Dunn's tests. Data gathered were interpreted through the lens of isomorphism and Oliver's (1991) strategic responses to institutional processes. Findings - The study revealed that in the voluntary disclosure period, auditees responded mainly with acquiescence, motivated by mimetic isomorphic pressure. In the mandatory disclosure period, auditee responses ranged from acquiescence to dismissal of corporate governance regulation (i.e. coercive isomorphic pressure). Auditor reporting of CGA findings was found to be heterogeneous, suggesting that normative and mimetic isomorphism did not homogenize auditor practices. Practical implications - The absence of uniform auditee responses to CGA regulation during the mandatory disclosure period suggests that the purpose of mandating the regulation has not yet been achieved and may signal inadequate coercive isomorphic pressure from the Financial Reporting Council of Nigeria (FRCN). Similarly, heterogeneous reporting of CGA findings by corporate governance auditors inhibits the comparability of audit findings, limiting their value for information users. Originality/value - This study examines corporate governance auditor practices and auditee responses to corporate governance audit regulation.
