SUMMARY This study examines whether a company's business strategy is an underlying determinant of the strength of its internal control over financial reporting (ICFR) and auditors' internal control reporting quality. Organizational theory suggests that companies following an innovative “prospector” strategy are likely to have weaker internal controls than companies following an efficient “defender” strategy. Consistent with theory, we find that firms with greater prospector-like characteristics are more likely to report and less likely to remediate material weaknesses, incremental to known determinants of material weaknesses. We also find that auditors' internal control reporting quality is lower among clients with greater prospector-like characteristics when measured using the timeliness of reported material weaknesses. Our findings indicate that business strategy is a useful summary indicator for evaluating companies' internal control strength and suggest that internal control reporting is an important area for audit quality improvement among prospector-like clients.

SUMMARY:We examine the relationship between auditor competition and the likelihood of financial restatements that occur as a result of failures in the application of generally accepted accounting principles (GAAP). Policy makers and audit market participants have expressed concern that the current level of auditor competition is low, resulting in a negative impact on audit quality. However, we find that restatements are more likely to occur in metropolitan statistical areas (MSAs) that have higher auditor competition. The association between audit market competition and restatements is statistically and economically significant. Our finding of a positive relationship between the likelihood of restatement and audit market competition is relevant to the ongoing debate regarding audit quality and the concentration of audit markets.

This study examines whether audit clients engage in internal control opinion shopping activities and whether audit market competition appears to facilitate those activities. Regulators have long been concerned about the impact of both audit market competition and opinion shopping on audit quality. We adopt the framework developed in Lennox (2000) to construct a proxy to measure the tendency that clients engage in internal control opinion shopping activities. Our empirical results suggest that clients are successful in shopping for clean internal control opinions. In addition, we find evidence that internal control opinion shopping occurs primarily in competitive audit markets. Finally, our results indicate that among auditor dismissal clients, opinion shopping is more likely to occur when dismissals are made relatively late during a reporting period and when audit market competition is high. Our findings have implications for the current policy debate regarding audit quality and audit market competition.
