The Use and Characteristics of Foreign Component Auditors in U.S. Multinational Audits: Insights from Form AP Disclosures*

This paper investigates the common, yet previously opaque, practice of using foreign audit firms (component auditors) to conduct portions of audit work for U.S. public companies. U.S. regulators have expressed concern for the transparency and quality of audits using component auditors. Employing data disclosed in the newly mandated PCAOB Form AP, we find that component auditor use is largely structural, determined by the size and complexity of clients' multinational operations. We do not find that the mere use of component auditors is detrimental to audit outcomes, but rather the amount of work conducted by component auditors is associated with lower audit quality (i.e., higher likelihood of misstatement), higher likelihood of nontimely reporting, and higher audit fees, which collectively suggest that component auditor engagements are associated with adverse outcomes. Furthermore, we find that only the work performed by less competent component auditors and those facing geographic and cultural/language barriers, including significant geographic and cultural distance, weak rule of law, and low English language proficiency, is associated with adverse audit outcomes. Overall, these findings provide initial archival evidence that the use of certain component auditors on U.S. multinational audits is associated with audit coordination issues, which suggests that PCAOB Form AP disclosures provide relevant information.     

Do Accounting Firm Consulting Revenues Affect Audit Quality? Evidence from the Pre‐ and Post‐SOX Eras

In recent years, public accounting firms have experienced a steady increase in the proportion of their revenues generated from consulting services. Although growth in consulting revenue following the Sarbanes‐Oxley Act (SOX) has been generated primarily from services provided to nonaudit clients, regulators have expressed concerns about the potential implications of this increase for audit quality. In contrast, accounting firms assert that the expertise developed by their consulting professionals helps them to provide better quality audits. We examine the relation between the proportion of accounting firm consulting revenue to total revenue and audit quality and investor perceptions of audit quality. Because SOX drastically altered the source of consulting revenues for public accounting firms, we also separately examine these relations in the pre‐ and post‐SOX eras. We find evidence suggesting that before SOX, higher proportions of audit firm consulting revenues negatively impacted both audit quality and investor perceptions of audit quality. However, we do not find a statistically significant association between audit firm consulting revenues and either audit quality or investor perceptions of audit quality following SOX. Our analyses suggest that even if these relations exist following SOX, the potential economic magnitude of the effect is small.     

Is Audit Committee Equity Compensation Related to Audit Fees?*

Section 301 of the Sarbanes‐Oxley Act (SOX) implicitly assumes that audit committees can independently determine audit fees. Critics of section 301 have questioned this assumption in particular, and the efficacy of section 301 more generally. In response, the SEC issued a concept release in 2015 calling for public disclosure of the process that audit committees follow for determining auditor compensation. Motivated by these calls and the widespread use of stocks and options to compensate firms' independent directors, we examine the relation between equity compensation granted to audit committee members and audit fees. Using a sample of 3,685 firm‐year observations during 2007–2015, we find a negative relation between audit committee equity compensation and audit fees, consistent with larger equity pay inducing audit committee members to compromise independence by paying lower audit fees. These findings are robust to controlling for endogeneity, firm size, alternative measures of equity compensation, alternative samples, and an alternative treatment of extreme values. We further show that larger equity compensation is associated with lower earnings quality. We also find that the negative effect of equity compensation on audit fees is stronger when city‐level audit market competition is high. However, this negative relation disappears when (i) firms face high litigation risk, (ii) auditors have stronger bargaining power, (iii) the audit committee includes a high proportion of accounting experts, and (iv) auditors are industry experts. Our results are relevant for regulators and investors.     

Auditors' Fee Premiums and Low‐Quality Internal Controls*

We examine the relation between low‐quality internal controls and audit fee premiums. Using a novel data set of audit hours and audit fees we find, consistent with the audit risk model, that auditors increase their effort (hours) owing to low internal control quality. We find that auditors also charge a significant fee premium to clients with internal control weaknesses. This premium is observed for severe internal control weaknesses and companies with low‐quality alternative governance mechanisms. The results are robust to multiple methods to address endogeneity, including company fixed effects, difference‐in‐differences design, and a propensity score‐matched sample. Taken as a whole, low internal control quality leads to fee premiums, which are a deadweight loss to client companies.     

Did the PCAOB's 2009 Office Expansion Improve Audit Quality?*

We investigate whether the PCAOB's decision to expand the number and location of its inspection offices in 2009 improved the reliability of US audits. We use a difference-in-differences empirical design to consider the impacts of the expansion on audit quality and find that audit quality significantly improved following the PCAOB's expansion in markets where new offices opened relative to markets without an office opening. We find that the improvement in audit quality appears to be driven by auditors' reaction to real changes in PCAOB oversight and that triennially inspected auditors appear to be impacted the most by this office expansion. Our findings provide new insights into the PCAOB's operational decision-making and suggest that the regulator's additional investment in audit oversight was effective in improving audit quality.     

Common Auditors and Private Bank Loans*

We show that when banks and borrowers share the same audit firm, borrowers receive lower interest rates, after controlling for potentially confounding director connectedness. The common auditor effect is observed only for opaque borrowers, and is greatest when the same audit engagement office audits the bank and borrower. A common auditor connection also matters more for longer‐tenured auditors, for geographically proximate borrowers, and when the syndicate involves fewer lenders. The effect does not hold for auditors recently sanctioned by the PCAOB. Finally, the interest rate discount is not the consequence of homophily or biased decision making, based on a comparison of postloan performance of firms with common auditor loans versus those with noncommon auditor loans.     

Auditor Responses to Shareholder Activism

In this paper, we investigate how auditors respond to shareholder activism against their clients. Our study is important because activism may be viewed by auditors as a source of increased engagement risk, thereby impacting audit outcomes. The potential relationship between shareholder activism and audit outcomes leads us to predict that activism targets will pay higher audit fees and also will be more likely to receive adverse internal control opinions (ICOs) and first‐time going concern opinions (GCOs). Our results, which support all three predictions, suggest that the public scrutiny associated with activism campaigns heightens auditors' concerns about reputational damage and litigation risk. Consistent with this notion, we find that activism targets are more likely to experience accounting‐related lawsuits. We also find that the increased likelihood of adverse ICOs documented in our baseline tests reflects higher‐quality reporting rather than increased auditor conservatism. Overall, our findings suggest that activism campaigns spur auditor diligence while also increasing the possibility of negative outcomes that may not be fully anticipated by activist investors.     

Auditing Goodwill in the Post‐Amortization Era: Challenges for Auditors

The elimination of goodwill amortization in 2001 brought about significant change in how companies are required to account for goodwill. This change in accounting also brought with it new challenges for auditors, namely evaluating the reasonableness of management's assumptions related to goodwill valuation. In addition to introducing technical challenges, this task is particularly difficult given the misalignment in incentives it creates between managers who likely prefer to avoid recording an impairment and auditors who seek to minimize the bias in management's impairment testing. This study focuses on the consequences of the misaligned incentives that auditors face under the current goodwill assessment process. We find that the decision to record a goodwill impairment is associated with an increase in the probability of auditor dismissal. Consistent with the presence of significant friction with clients, our results also indicate that the likelihood of auditor dismissals is negatively related to the favorability of the impairment decision. Furthermore, we find that companies impairing goodwill prior to dismissing auditors subsequently employ auditors that are, on average, more favorable to clients in their impairment decisions.     

PCAOB Inspections and the Differential Audit Quality Effect for Big 4 and Non–Big 4 US Auditors*

In this study, we investigate whether the increase in regulatory scrutiny epitomized by the initial PCAOB inspection impacted audit quality differentially for Big 4 and non–Big 4 auditors to better understand the consequences of PCAOB inspections for different audit firm types. Because of competing views on the effect of PCAOB inspections, the relation between PCAOB inspections and the audit quality differential between Big 4 and other auditors is an empirical issue. Empirically, we take the endogenous choice of auditor as a given and utilize a difference‐in‐differences specification that takes into account the staggered timing of the initial PCAOB inspection for different‐sized auditors in the United States. Our results suggest that the initial PCAOB inspection improved audit quality more for Big 4 auditors than for other annually inspected or triennially inspected non–Big 4 auditors. We also examine annually and triennially inspected non–Big 4 auditors separately, and find that the pre‐post Big 4/non–Big 4 differential audit quality effect is more pronounced for the triennially inspected non–Big 4 firms. In the larger context of the highly concentrated US audit market, our findings that PCAOB inspections accentuate the Big 4/non–Big 4 audit quality differential are of potential interest to public company audit clients contemplating an auditor change, investors interested in learning about the consequences of PCAOB inspections, regulators concerned about the Big 4 dominance of the US audit market, and academics investigating audit quality differences.     

Do Auditors Accurately Predict Litigation and Reputation Consequences of Inaccurate Accounting Estimates?

To effectively manage audit risk, auditors must correctly predict the potential litigation and reputation consequences associated with inaccurate accounting estimates. Accurate predictions are critical because underestimation of negative consequences leads to excess legal exposure and overestimation leads to overauditing. Our paper examines whether auditors correctly anticipate these litigation and reputation outcomes. We provide manager‐ and partner‐level auditors with case facts from an auditor negligence lawsuit and ask them to predict the proportion of juries that will return verdicts against their firm. We then compare auditors' predictions to the actual verdicts we observe when we provide the same set of case facts to mock jurors who deliberate as part of juries. We find that auditors overestimate the likelihood of negligence verdicts, especially when audit quality is relatively high. Our supplemental measures help explain the reasons for this overestimation: auditors tend to underestimate jurors' perceptions of audit quality and willingness to attribute inaccurate estimates to situational factors. Finally, we examine auditors' predictions about how a news article about the litigation will affect their reputation with the general public. Similar to our litigation results, we find that auditors tend to overestimate the article's negative impact on auditor reputation. Collectively, our findings suggest that auditors overestimate litigation and reputation consequences resulting from inaccurate accounting estimates. This overestimation is consequential as it leads to inefficient allocation of audit resources.     

Learning by Doing and Audit Quality*

In this study, we present a nonstrategic, dynamic Bayesian model in which auditors' learning on the job and their choice of professional services jointly affect audit quality. While performing audits over time, auditors accumulate client‐specific knowledge so that their posterior beliefs about clients are updated and become more precise (that is, precision is our surrogate for audit quality) — what we call the learning effect. In addition, auditors can enrich their knowledge accumulation by performing nonaudit services (NAS) that, in fact, may influence clients' managerial decisions — what we call the business advisory effect. This advisory effect permits auditors to anticipate and to learn about changes in clients' business models, which in turn improves their advisory capacity. These dual “learning” and “advisory” effects are interdependent and mutually reinforcing. The advisory effect of NAS may increase or reduce auditors' engagement risk. We show that large professional fees can induce auditors to provide NAS that increase engagement risk and diminish audit quality. However, when NAS reduce engagement risk and increase audit quality, auditors may provide NAS without charging clients. The feature that distinguishes our study — the interdependence between the learning and advisory effects — provides new insight into the trade‐off between audit fees and audit quality. Consequently, our analysis helps explain why the scope of the audit has evolved over time and why the boundaries between audit and NAS are constantly shifting. A recent example of such a shift is that the Sarbanes‐Oxley Act adds control attestation to audits for public companies traded in U.S. markets.     

IQ and Audit Quality: Do Smarter Auditors Deliver Better Audits?

This study examines the role of an individual auditor's cognitive ability in delivering high‐quality audits. Our results from analyzing archival data from Sweden show that audit partners' IQ scores obtained from psychological tests are positively associated with going‐concern audit reporting accuracy and audit fee premiums. We also find some, albeit weak, evidence that audit partners' IQ scores are negatively associated with the income‐increasing abnormal accruals of the client. These results suggest that, although audit services are standardized through various control mechanisms and audits are conducted by teams rather than by individual auditors, the cognitive ability of audit partners responsible for an audit remains important in delivering high‐quality audit services.     

Investor Sentiment,Misstatements, and Auditor Behavior*

High investor sentiment has been linked with opportunistic managerial behavior in the face of more optimistic investors and analysts. We extend this line of work by documenting that the likelihood of misstatements is higher when sentiment is high. Although this would suggest elevated audit risk, we posit that a contemporaneous reduction in auditors' litigation cost could drive down audit fees and going concern opinion (GCO) reporting conservatism in order to please clientele. Consistent with this notion, we document that auditors charge lower fees and report GCOs less conservatively when sentiment is high. However, this reduction in reporting conservatism is unwarranted; results reveal that auditors are less likely to issue GCOs to clients which subsequently file for bankruptcy during high sentiment periods. We conduct additional tests to examine whether auditors' litigation costs indeed vary with sentiment and document that auditors are less likely to be sued and the market reacts less negatively to misstatement announcements when sentiment is high. Collectively, our findings suggest that, although misstatement risk is increasing with sentiment, auditors' litigation risk actually declines.     

Economic Consequences of IFRS Adoption: The Role of Changes in Disclosure Quality*

This study adopts a two‐step approach to highlight the disclosure quality channel that drives economic consequences of IFRS adoption. This approach helps address the identification challenge noted by prior research and offers direct evidence on the role of disclosure quality. In the first step, we document the impact of the IFRS mandate on changes in disclosure quality proxied by the granularity of line item disclosure in financial statements. We find that IFRS‐adopting firms provide more disaggregated information upon IFRS adoption, such as more granular disclosure of intangible assets and long‐term investments on the balance sheet and greater disaggregation of depreciation, amortization, and nonoperating income items on the income statement. In the second step, we link the observed disclosure changes to the benefits and costs of IFRS adoption. We show that greater disaggregated information due to IFRS adoption enhances market liquidity and decreases information asymmetry, but does not affect audit fees differentially. Our evidence has implications for standard setters as they evaluate cost‐benefit trade‐offs when considering disclosure changes in the future.     

La valeur économique de l’audit et son efficacité dans le fonctionnement de l’école publique

Les auteurs examinent l’incidence de l’audit sur le fonctionnement de l’école publique en poursuivant deux objectifs : déterminer si les audits procurent des avantages économiques aux parties prenantes et définir l’incidence de la complexité des règles à observer sur l’efficacité de l’audit. Utilisant des données relatives au temps consacréà l’audit et profitant de l’occasion unique offerte par la Quality Basic Education Act en Georgie, les auteurs estiment le rendement relatif des activités des arrondissements scolaires au moyen d’une méthode stochastique d’estimation des frontières. Ils constatent que l’audit produit de véritables avantages économiques pour les parties prenantes en atténuant le manque d’efficience de l’utilisation des ressources scolaires. Ils constatent également que la rigueur des règles à observer réduit l’efficacité de l’audit mais que l’expérience des auditeurs peut contribuer à surmonter ce problème. Le fait que les coûts d’audit ne soient pas communiqués entrave la réalisation d’une analyse coûts‐avantages des nouvelles exigences. L’analyse des auteurs vient confirmer la thèse selon laquelle l’audit est indispensable à l’établissement de mécanismes de gouvernance et la communication des coûts d’audit est importante dans l’évaluation adéquate d’une nouvelle politique. Les données pertinentes peuvent être obtenues auprès des sources publiques indiquées dans le texte.     

Audit Regulation and Cost of Equity Capital: Evidence from the PCAOB's International Inspection Regime*

This study investigates the relation between audit regulation and cost of equity capital. There is scant empirical evidence on this relation because changes in audit regulation are frequently accompanied by other major regulatory changes. We exploit variation in the timing of regulatory changes induced by foreign governments' staggered allowance of PCAOB inspections. Using a difference-in-differences design, we find that foreign SEC registrants with auditors from countries that allow PCAOB inspections enjoy a lower cost of capital, relative to foreign SEC registrants with auditors from countries that prohibit inspections. Furthermore, we find that this cost of capital effect is attenuated for companies with higher-quality governance mechanisms. Finally, we document that inspection access is associated with higher-quality analyst forecasts, which suggests that this change in audit regulation reduces information risk for market participants.     

Whistleblowing Allegations,Audit Fees,and Internal Control Deficiencies*

We investigate whether audit fees and auditors' opinions on internal controls are associated with whistleblowing allegations externally filed to regulatory agencies. We find that firms subject to whistleblowing allegations have significantly higher audit fees, regardless of the substance of these allegations, whereas an auditor is more likely to issue an adverse opinion on internal controls when the allegation is substantiated, rather than frivolous. Further, our findings suggest that auditors are involved in the auditing of whistleblowing when the allegation is still in an internal stage. We also show that firms subject to external whistleblowing allegations have a lower likelihood of restating financial statements prepared in the allegation year when greater audit effort is made in that year. Our study is among the first to demonstrate the role of auditors in the context of whistleblowing.     

Public Company Audits and City‐Specific Labor Characteristics

Prior research emphasizes the centrality of audit offices in understanding auditing practices, and documents significant interoffice variation in audit outcomes based on industry expertise and office size. Our study examines how two city‐specific labor characteristics also affect audit offices and local audit markets: the city's average educational attainment, and the number of accountants in a city, which proxy for a city's human capital. Our argument draws on the urban economics literature and predicts that the level of human capital in a city is positively associated with an audit office's ability to conduct high‐quality audits. As expected, there is a positive association between audit quality (quality of audited earnings and accuracy of going‐concern reports) and average education level in the city in which the lead engagement office is located. This association is generally significant for both Big 4 and non‐Big 4 offices, but is relatively stronger for non‐Big 4 firms that are more tied to local labor markets. A company is also more likely to choose a non‐Big 4 auditor in cities with higher educational levels and relatively more accountants, and there is evidence of higher non‐Big 4 audit fees as a city's education level increases. Collectively, these results suggest that local labor characteristics affect audit offices, audit quality, and the ability of non‐Big 4 auditors to compete with Big 4 auditors in the audits of public companies.     

The Importance of Account Relations when Responding to Interim Audit Testing Results*

Auditors are expected to plan and adapt audit programs in response to changes in risk associated with each client. Results in the existing research have been mixed regarding whether auditors respond to changes in risk. Two possible explanations for the lack of responsiveness to changes in risk found in the existing research are that auditors succumb to profit pressure, and that researchers only analyze responses in the risky accounts without considering related accounts. This paper experimentally tests how auditors respond to changes in risk of material misstatement identified by means of interim audit testing results. The response to changes in risk of material misstatement is analyzed using planned audit hours across related financial statement accounts and at varying levels of profit pressure. Results indicate the following primary findings: (a) auditors respond to changes in risk of material misstatement by increasing planned audit hours in accounts related to the risky account, and (b) profit pressure does not affect the auditor's response to changes in risk. These results indicate that the relations between accounts must be considered in order to identify the auditors' response to changes in risk of material misstatement. In addition, the results are consistent with audit firms decreasing the emphasis on profit pressure due to the current importance that the market places on audit quality.
