Non-audit service and auditor independence: an examination of the Procomp effect

This paper examines whether non-audit service provision impairs auditor independence, and whether the degree of auditor independence in Taiwan changed in the wake of the 2004 Procomp scandal. The auditors involved in the Procomp affair were suspended from practice for 2 years and were sued, and we posit that these unprecedented sanctions and litigation affected subsequent auditor behavior. Considering the measurement errors involved in discretionary accruals, we propose an alternative analytic approach in which the dependent variable in the regression analysis is the difference between audited earnings and forecast earnings, scaled by total assets, and the primary independent variable is the non-audit fees ratio. After controlling for the effects of financial leverage, operating and market performance, industry, company size, audit firm size, management forecast error, and management attempts to manipulate earnings, regression analysis indicates that the coefficient for non-audit fees ratio is negative and significant in 2003 but not in 2004. Using non-audit fees instead of non-audit fees ratio to conduct the regression analysis yields similar results. This finding is consistent with the notion that auditors make a trade-off between gaining service fees and avoiding litigation and reputation loss. Limitations and policy implications are also offered.

Opaque auditor dismissal disclosures: What does timing reveal that disclosures do not?

Auditor resignations provide a clear signal of accounting problems or heightened audit risk; however, registrants label the vast majority of auditor changes as dismissals, which carry more ambiguity. Motivated by the opacity of current dismissal disclosures, this study explores the usefulness of these disclosures compared to an alternative signal – the timing of the dismissal within the reporting year – for inferring the causes and implications of dismissals. Dividing the reporting year into key periods, we find that the probabilities of future restatements, material weaknesses, and delistings following a dismissal generally increase within the reporting year while negative circumstances disclosed do not. Analyses suggest that the timing patterns are caused by burgeoning, yet undisclosed, conflicts between the client and the outgoing auditor, rather than by transition difficulties involving the new auditor (as prior literature claims). The timing patterns strongly persist after controlling for negative circumstances that registrants disclose in the dismissal filing, suggesting that the disclosures are not fully revealing. In fact, disclosed negative circumstances have no incremental predictive power for future restatements and delistings. Our results suggest a severe lack of informativeness of current disclosures and support previous calls for improvement of dismissal disclosure regulation.     

The effect of small audit firms’ failure to remediate the PCAOB’s quality control criticisms on audit market segmentation

This paper examines the role of the Public Company Accounting Oversight Board (PCAOB) quality control inspection program on market segmentation of small firms’ audit services. Specifically, we investigate how non-remediation of quality control criticisms (QCCs) affects the supply and demand of low-quality audits. We find that remediation of QCCs improves audit quality for small accounting firms. However, some small accounting firms do not remediate QCCs (NR firms) and continue to provide low audit quality. We investigate how NR clients react to the disclosure of non-remediation of QCCs. We find that NR clients with low agency costs are more likely to retain NR firms after the disclosure of non-remediation. This finding is consistent with our expectation that voluntary QCC remediation creates a low-quality audit market segment for NR firms. Our findings suggest that the public disclosure of QCCs is not sufficient to remove low-quality auditors. Instead, NR clients use the disclosure of non-remediation of QCCs as a signal to sort themselves into segments based on their demand for audit quality. We are the first to study and find that PCAOB inspections, and specifically the voluntary nature of remediation and public disclosure of lack of remediation, create market segmentation.     

Third-party auditor liability and financial restatements

We examine whether U.S. state-level third-party auditor liability (TPAL) regimes affect firms' financial restatement decisions. Using a sample of 34,409 firm-year observations from 2003 to 2018, we find that state-level TPAL is significantly negatively related to the likelihood of firm-level financial restatements. We also observe that the negative relationship between TPAL and financial restatements persists for a subsample of firms with income-increasing financial restatements and the ‘restatement of torts standard’ (one of the more expansive subgroups of TPAL). Using a difference-in-differences regression design, we find that an increase in state-level TPAL regimes strengthens the negative relationship between TPAL and the incidence of restatements. Our main finding remains robust across several sensitivity tests. Finally, we find that the negative relationship between TPAL and restatements is more pronounced when firms are subject to greater litigation risk and when firms are audited by non-specialist auditors. Overall, we show that TPAL has important implications for client firms' financial restatements.     

Common auditors and internal control similarity: Evidence from China

This study investigates how important common auditors are to internal control similarity between two firms. Based on a less concentrated audit market in China, we find that firm-pairs with common auditors enforce a similar internal control system. This inference holds after accounting for other social connections, examining internal control components, using alternative measures of internal control, adopting finer industry classifications, constructing alternative internal control similarity, running auditor switch tests, and addressing endogeneity problems. Additional analyses indicate that auditor style and information sharing serve two underlying mechanisms to undergird the documented relationship. Finally, our evidence suggests that high-centrality firms in auditor networks are associated with better financial reporting.
