Audit partner industry specialization and audit report lag: does changing in the audit reporting requirements matter?

Abstract

Purpose This study aims to examine the relationship between the individual auditor’s industry specialization and the audit report lag (hereafter ARD). Further, it explores whether changing in the audit reporting requirement (i.e. the adoption of ISA701) influences the auditor’s industry specialization effect on the ARD. Design/methodology/approach A large data set of companies listed on the NASDAQ OMX Stockholm over the period 2010–2019 has been analyzed. Least squares regressions have been estimated to provide empirical evidence for the researched hypotheses. Findings The research findings indicate that the ARD is shorter for client firms audited by an industry specialist audit partner. Testing for the moderating role of changing in the auditing reporting regulation on the relation between the audit partner’s industry specialization and the ARD, the authors reveal that all client firms (except client firms with industry specialist audit partners) experienced an increase in the ARD. Overall, the baseline regression findings are found to be robust to the endogenous auditor choice and multiple measures of both the ARD and the auditor’s industry specialization. Originality/value This paper provides novel evidence on the relationship between the audit reporting lag and industry specialization from the individual auditor perspective, an issue that has hitherto been unexplored. The regression results further contribute to the upsurge debate about the consequences of changing in the audit reporting model by providing consistent support for the importance of industry specialization of the audit partner in minimizing costs derived from the former requirement.
