PCAOB inspection deficiencies and future financial reporting quality: Do the types of deficiencies matter?
研究了PCAOB检查报告是否有助于预测未来财务错报风险，发现审计师未能理解客户会计程序或政策是最严重的缺陷类型，且对四大与非四大事务所的影响不同。
Abstract This study examines whether PCAOB inspection reports are useful for signaling the risk of misstatements in future periods and the extent to which different types of audit deficiencies predict future misstatements. We find that, after the inspection report is issued, PCAOB‐identified audit deficiencies are positively associated with future misstatements for the audit firm's entire client portfolio. When we examine different types of deficiencies, we find that an auditor's failure to understand the client's accounting procedures or policies is the most detrimental type of deficiency for future reporting quality. We also examine the deficiency types for Big 4 versus non–Big 4 firms separately. The results show that an auditor's failure to understand the client's accounting procedures or policies is the only deficiency type that is positively associated with future misstatements for Big 4 firms. For non–Big 4 firms, however, future misstatements are predicted by an auditor's failure to understand the client's accounting procedures or policies, inadequate substantive testing, and inadequate going‐concern assessments. Our study has important implications given the concerns raised by auditors regarding the usefulness of PCAOB inspections.
