SUMMARY We investigate how the number of audit committee chair positions and other audit committee financial expertise positions held by the audit committee chairman and the audit committee financial experts affects their ability to oversee a company's financial reporting process. We argue that these two audit committee roles are vital to the functioning of the audit committee and that their over commitment affects audit committee oversight and the firm's financial reporting quality. We observe a significant negative association between financial reporting quality and the number of audit committee chair positions and other audit committee financial expertise positions held by the audit committee chairman. We also find a significant negative association between financial reporting quality and the number of audit committee chair positions and other audit committee financial expertise positions held by audit committee financial experts. Firms with busy audit committee chairs or busy financial experts have significantly higher levels of abnormal accruals, and are more likely to meet or beat earnings benchmarks, which is consistent with the busyness hypothesis. This adverse effect, nonetheless, does not extend to nonaudit committee chairs and nonaudit committee financial experts. We interpret these results to indicate that the busyness of the audit committee chair and financial expert weakens the monitoring and oversight role that audit committees play in the financial reporting process.
SUMMARY The constricted mandatory audit partner rotation rules for U.S. public companies have fueled intense debate among the profession, regulators, and policymakers. This topic remains controversial, but neither side has provided evidence of the consequential benefits and costs of mandatory rotation. While rotation effects on audit quality have been examined, we empirically examine its effects on two audit production costs: audit fees and audit timeliness. We find significantly higher audit fees and significantly longer audit report lags in the period immediately following mandatory audit partner rotation. These effects are more pronounced for non-Big 4 auditors, larger clients, and audit offices that are not industry specialists. Moreover, the audit fee and audit timeliness effects persist in successive audit partner rotations, suggesting that client-specific knowledge gained through longer audit firm engagement does not completely mitigate loss of client-specific knowledge at the partner level. Our findings provide new empirical evidence supporting the profession's arguments that mandatory audit partner rotation is costly to multiple stakeholders, including clients, auditors, and investors.

SUMMARY: Audit partner rotation has received considerable attention globally and in the U.S. since the Sarbanes-Oxley Act of 2002 accelerated the rotation period from seven to five years and expanded the cooling-off period from two to five years. However, research on the effects of audit partner rotation on financial reporting quality in the U.S. is virtually non-existent, largely due to the absence of publicly available information on audit partners. Using a novel approach to determine audit partner rotation, we investigate the effect of rotation on financial reporting quality in the U.S. We find evidence of lower financial reporting quality following an audit partner change. Specifically, we find lower financial reporting quality during the first two years with a new audit partner relative to the final two years with the outgoing partner. We find the lower financial reporting quality to be more prevalent for larger clients. Further analyses suggest the initial year post-rotation presents audit challenges for Big 4 partners, which persist for at least three years for non-Big 4 partners. Audit challenges also appear greater for city-level non-industry specialist auditors and smaller audit offices. We discuss the implications of our results for regulators, policymakers, and the profession at large.
