We examine the impact of auditors’ reputation impairments on their private-client market share to explore how conducting low-quality audits affects auditors’ broader client portfolios. Prior evidence implies that an audit office loses public-client market share after a client announces a restatement. However, auditors’ private clients may be less concerned about auditor reputation and quality, given that they have lower agency costs and their financial statement users are often creditors that can rely on direct monitoring to narrow information asymmetry. Also, differences between public and private company audits cast doubt on whether public-client restatements are relevant to private clients. We find that the private-client market share of a Big Four audit office falls by, on average, 5 percent the year after a public client announces a restatement. This evidence suggests that Big Four offices cannot simply replace lost public-client revenue with private-client revenue after suffering reputation damage.

Using online job postings data, we explore whether auditors adjust their human capital in response to clients' cyber breach incidents. We find that audit offices increase their demand for cybersecurity specialists after their clients' cyber breaches, implying that cyber breaches change not only client risk but also their auditor's production function. Consistent with expectations, we document that this impact is larger when breaches involve their own clients (rather than those of peer offices within the same audit firm) and when breaches directly involve financial information. Our evidence holds for both cyber‐focused and non‐cyber‐focused offices, highlighting the broad impact of cybersecurity risks on audit practices. Additionally, we find that audit offices with relatively high investment in cybersecurity human capital are better able to preserve their market share among clients in high‐cyber‐risk industries after a client's cyber breach.

We document that firms held by mutual fund managers who have public accounting experience earlier in their careers exhibit higher‐quality financial reporting, as evidenced by a lower likelihood of financial statement restatements. Additional evidence shows that fund managers with public accounting experience are more likely to conduct site visits to their portfolio firms and discuss accounting policy–related topics during those visits. Moreover, the restatement likelihood falls after fund managers' site visits, particularly when they raise accounting policy–related issues during their visits. In cross‐sectional results consistent with expectations, we find that the role that fund manager public accounting experience plays is amplified when the firm suffers more severe agency problems, firm information asymmetry is worse, fund managers are more risk averse, fund managers have prior work experience at larger accounting firms, fund managers hold a larger proportion of the firm's shares, or there is coordination among mutual funds. Collectively, our evidence suggests that fund managers with public accounting experience impose stricter external monitoring on their portfolio firms' financial reporting choices.

In examining the loan contracting implications of SEC investigations, we document that banks charge higher loan spreads when borrowers are under investigation, with the rise in interest rates varying predictably with lender characteristics. Further, our evidence implies that the debt pricing impact of SEC investigations is amplified for borrowers suffering worse credit quality and information asymmetry as well as those relying more on bank loans. These findings suggest that banks perceive increased risk for borrowers under SEC scrutiny while also leveraging their knowledge of the investigations to extract rents. Supplemental analyses reveal tighter nonspread loan terms and a higher likelihood of amending existing loan contracts during SEC investigations. Additionally, the tightening of loan terms reverses for investigations that conclude without enforcement actions. Overall, our research identifies an economic cost of SEC investigations and alerts regulators to these costs when deciding whether to launch an investigation.

Relying on the frequency of typos in engagement partners’ graduate theses to measure their conscientiousness, we find that more conscientious partners conduct higher-quality audits, evident in that they are more likely to require an audit adjustment. Our core results hold for both upward and downward adjustments, implying that being conscientious is not equivalent to being overly conservative. Consistent with DeAngelo’s (1981) theory, cross-sectional evidence suggests that the role that partner conscientiousness plays in audit quality comes through both the auditor competence and independence channels. Additionally, we find that the frequency of partner thesis typos is negatively associated with auditor effort. Collectively, our evidence implies that engagement partner conscientiousness plays a major role in shaping audit outcomes.
