The impact of PCAOB reports containing audit deficiencies on non-U.S. audit firms: Initial evidence

Abstract

The Public Company Accounting Oversight Board (PCAOB) regularly conducts inspections of non-U.S. audit firms. Based on 243 PCAOB inspection reports of non-U.S. audit firms, published by the PCAOB between January 2006 and December 2011, we examine involuntary dismissals, voluntary resignations, and voluntary deregistration of inspected non-U.S. audit firms following PCAOB reports containing audit deficiencies. Our results show that 24 out of 1,604 clients of non-U.S. audit firms have dismissed their auditors within one year following the disclosure of audit deficiencies in PCAOB reports, and that only four of these 24 clients appointed successor auditors with clean PCAOB reports. Also, we find only four auditor resignation cases from the 1,604 clients of non-U.S. audit firms within one year after they received a PCAOB report containing audit deficiencies. Finally, 22 non- U.S. audit firms voluntarily ceased to be registered with the PCAOB either during the inspection process or after they received PCAOB reports containing audit deficiencies. Compared to registered non-U.S. audit firms, these deregistered non-U.S. audit firms have relatively fewer resources (e.g., fewer partners and professional staff, smaller offices) and, thus, may not be able to bear compliance costs (e.g., costs associated with preparation for inspections) associated with PCAOB inspections. This study provides insights regarding the impact of PCAOB international inspections.
