Calls from practice suggest that audit committee members with industry expertise can improve audit committee effectiveness. Nevertheless, regulators and the extant literature have focused on the financial expertise of the audit committee. We posit that audit committee industry knowledge is valuable because accounting guidance, estimates, and oversight of the external auditor are often linked to a company's operations within a particular industry. Taking a holistic view, we examine two measures of financial reporting quality (financial restatements and discretionary accruals) and two measures of external auditor oversight (audit and nonaudit fees). As predicted, we find that audit committee members who are both accounting and industry experts perform better than those with only accounting expertise. We also find that in certain instances, supervisory experts who are also industry experts perform better than supervisory experts alone. Overall, these results suggest that industry expertise, when combined with accounting expertise, can improve the effectiveness of the audit committee in monitoring the financial reporting process.

While current audit standards explicitly state engagement partner tenure requirements, firms have flexibility in managing the rotation process. We conduct semi-structured interviews with 20 U.S. audit firm partners who share their experiences on topics including how they identify appropriate candidate partners and what efforts they undertake to manage relationships with clients post-rotation. We investigate firms' motivation to manage the auditor-client relationship through the lens of Social Exchange Theory (SET), and we consider how likely outcomes of this rotation process map onto regulators' intent that a newly rotated partner provides a fresh perspective to the audit. Our study informs regulators and investors about the process by which engagement partners are selected for rotation, documenting that partner assignment is typically not random. Further, our finding that partner rotation is an extended process (rather than a single discrete event) has implications for audit researchers investigating the effects of partner rotation.
