Audit firms are organized as collections of geographically decentralized offices. Decentralization allows for increased proximity between offices and clients, improving the efficiency of auditors' interactions with client personnel. Yet decentralization also decreases the proximity between offices within each firm, potentially impeding auditors’ interactions with each other. We show that decreased proximity between offices reduces inter-office audit quality “spillovers” and that this effect is driven primarily by reduced monitoring and knowledge sharing. Our findings expand the “within office” view of audit production by demonstrating the importance of interactions between offices and the role of geographic proximity in facilitating them.

ABSTRACT Literature to date reveals relatively little about the role of expertise in auditor selection beyond basic preferences for Big 4 and industry specialist auditors. We hypothesize that audit committees whose members have no Big 4 auditing experience are likely to struggle when interviewing prospective Big 4 partners, leading such committees to draw on superficial, heuristic cues in lieu of conducting more substantive evaluations. To test this prediction, we obtain independent ratings of the facial attractiveness of audit partners identified from Form AP filings recently mandated by the US PCAOB. Our primary finding is that audit committees with no Big 4–experienced members are more likely to favor partners whose photographs raters view to be highly attractive. We characterize attractiveness as a superficial attribute for auditor selection because we detect no relation between attractiveness and accruals‐ or restatement‐based measures of financial reporting quality for audit committees with one or more Big 4–experienced members. We do find an inverse association between attractiveness and financial reporting quality for committees without this experience, likely reflecting the statistical implication of a selection bias. We conclude that auditing expertise mitigates the influence of superficial considerations in auditor selection, enabling audit committees to fulfill their stewardship role more effectively.

ABSTRACT We investigate whether non‐GAAP reporting affects the audit process and thereby the quality of the related financial statements. First, we provide evidence that auditors in numerous countries, including the United States and the United Kingdom, rely to varying degrees on non‐GAAP profit before tax as a benchmark for determining quantitative materiality. Then, using Premium Listed companies on the London Stock Exchange, we document that U.K. auditor reliance on non‐GAAP materiality benchmarks often results in a higher quantitative materiality amount and can lower audit quality. Although U.K. auditors appear skeptical of managers’ more aggressive non‐GAAP adjustments, auditors adopt more of management's low‐quality adjustments when auditor independence is weaker. In sum, our results suggest that non‐GAAP reporting can indirectly affect investors by reducing the rigor of the financial statement audit.

We find that non‐Big 4 audit offices with greater awareness of SEC enforcement are more likely to issue first‐time going‐concern reports to distressed clients; where SEC “awareness” is measured using (i) audit office proximity to SEC regional offices, and (ii) proximity to specific SEC enforcement actions against auditors. We also show that these non‐Big 4 audit offices issue more going‐concern opinions to clients who do not subsequently fail, indicating a conservative bias that reduces the informativeness of audit reports. This conservative reporting bias is also associated with higher audit fees and higher auditor switching rates. These findings are important because non‐Big 4 firms now audit 39 percent of SEC registrants and issue 88 percent of going‐concern audit reports. For Big 4 offices, we find some evidence that awareness of SEC enforcement may improve reporting accuracy by reducing Type II errors (failing to issue a going‐concern report to a company that fails), although the number of cases is small.
