Chief accounting officers and audit efficiency

Purpose - The purpose of this paper is to investigate the roles of chief accounting officer (CAO) on the efficiency of auditing process and to empirically examine the association between separate CAO appointment and audit report lag (ARL). Design/methodology/approach - This study employs firms listed in the US market from 2004 to 2012. The firm year having a CAO who does not simultaneously take other executive position is specifically identified. Firm years with job titles similar to CAO, such as chief accounting executive, vice president of accounting or corporate accounting executive, are categorized into the CAO group. Findings - The presence of a separate CAO significantly reduces ARL. With the appointment of a new auditor, the presence of a separate CAO is associated with lower ARL, suggesting the moderating effect of separate CAOs on the relationship between auditor change and audit delay. Practical implications - This study shows the importance of CAO, an executive who is specifically responsible for carrying out accounting functions. The findings suggesting the positive effects of separate CAO on external audit process and the timeliness of information should be of interest to firms, financial reporting users, auditors and regulators. Originality/value - While few studies address CAO-related issues, the roles of a CAO are not widely explored and how a separate CAO affects external audit process remains an open question. This study fills this gap and further documents the contribution of separate CAO in external audit work to enrich literature in executive roles and audit efficiency at the same time.
