Abstract
Purpose Part II of the Public Company Accounting Oversight Board (PCAOB) inspection report is released only when firms fail to remediate quality control criticisms and is intended to be a public signal of audit quality. The purpose of this paper is to reexamine whether audit clients react to the release of Part II of the PCAOB inspection report as a signal of audit quality.
Design/methodology/approach This study uses a difference-in-difference regression model to examine the association between the release of Part II of the PCAOB inspection report and an audit firm's change in market share. A sensitivity analysis is also performed to determine whether the main findings are robust to the timing of the release of the report and type of quality control criticism included in Part II of the inspection report.
Findings After controlling for the prior year's changes in market share, the authors find no evidence that clients react to the public release of Part II of the report. In the second part of the study, they examine when clients become aware of the contents of the Part II report prior to its release. Firms with audit performance criticisms experience a decrease in market share following the release of Part I. Firms with firm management criticisms experience a significant decrease in market share following the remediation period and before the public release of Part II.
Practical implications The results suggest that Part II of the PCAOB inspection report does not provide new information to the market. Clients appear to be aware of the information contained in Part II of the PCAOB inspection report prior to its release. The authors believe that the delay in releasing the Part II report may create an information imbalance, and the PCAOB may want to consider ways to improve the timeliness of the information.
Originality/value This study questions the generalizability of prior research which finds that Part II of the inspection report provides new information that is valued by the public company audit market as a signal of audit quality. The findings provide new evidence that the contents of Part II and the firm's ability to remediate the quality control concerns are known to audit clients prior to the public release.
