Audit quality: A mixed bag |
The PCAOB has raised alarms about rising audit deficiencies, with the deficiency rate reaching 43.6% in 2023, up from 40% in 2022. Erica Williams, the PCAOB chair, described these results as “completely unacceptable,” emphasizing the need for solutions rather than excuses. Despite the negative outlook, a deeper analysis of PCAOB data suggests that audit quality improvements may be more effective for smaller firms and international offices of larger firms. The PCAOB has conducted 12,031 inspections from 2009 to 2023, revealing that while Big Four firms have lower deficiency rates, Mid-Tier firms struggle significantly, with a deficiency rate of 63.8% in 2023. The PCAOB is responding by launching resources aimed at enhancing the performance of smaller audit firms, recognizing their critical role in investor protection.
