Auditor Independence and Fair Value Accounting: An Examination of Nonaudit Fees and Goodwill Impairments

Inadequate testing of fair value accounting estimates, including goodwill, is often cited as an audit deficiency in PCAOB inspection reports, and, in some cases, these deficiencies have led to enforcement actions against the auditor. As a result of these issues, the PCAOB recently proposed a new auditing standard for fair value accounting. While these regulatory actions suggest that auditors are challenged by the fair value regime of accounting for goodwill, they also highlight an area where the auditor could be influenced by their financial ties to a client. In this study, we test whether nonaudit fees are associated with goodwill impairment decision outcomes. Our results indicate that the nonaudit fees a client pays are inversely related to the likelihood of impairment in settings where goodwill is likely to be impaired. Additional examinations suggest that the negative relation between nonaudit fees and auditor independence is driven by clients who are most incentivized to exert their influence over the auditor.     

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.     

How Do Auditors Address Control Deficiencies that Bias Accounting Estimates?

Auditors commonly rely on reviewing management's estimation process to audit accounting estimates. When control deficiencies bias the estimation process by creating omissions of critical inputs, standards require that auditors replace or supplement review of management's estimation process with tests that can identify the omissions. Importantly, overreliance on reviewing management's estimation process when it has been biased by a control deficiency can result in auditor acceptance of an inappropriate accounting estimate. We use an experiment to examine whether auditors recognize the insufficiency of increased sampling of a biased estimation process and their selection of alternative tests to replace or supplement review of the biased estimation process. We find that a significant minority (33 percent) of Big 4 senior auditors erroneously increase tests of management's biased estimation process. We also find that auditors have difficulty selecting alternative tests to replace or supplement review of management's biased estimation process, frequently choosing tests that are either ineffective or inefficient. Our findings suggest that auditors often reach inappropriate judgments about the capability of audit evidence to address control deficiencies and that nonsampling risk (judgment risk) may be a larger risk than auditors realize.     

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.     

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.     

Who Cares about Auditor Reputation?*

I provide evidence on the demand for auditor reputation by examining the defections of Arthur Andersen LLP's clients following the accounting scandals and criminal conviction marring the auditor's reputation in 2002. About 95 percent of clients in my sample did not switch auditors until after Andersen was indicted for criminal misconduct regarding its failed audit of Enron Corp. I test whether the timing of client defections and the choice of a new auditor are consistent with managers' incentives to mitigate potentially costly information and agency problems. I find that clients defected sooner, mostly to another Big 5 auditor, if they were more visible in the capital markets; such clients attracted more analysts and press coverage, had larger institutional ownership and share turnover, and raised more cash in recent security issues. However, my proxies for agency conflicts — managerial ownership and financial leverage — are not associated with the timing of defections or the choice of new auditor. Overall, my study suggests that firms more visible in the capital markets tend to be more concerned about engaging highly reputable auditors, consistent with such firms trying to build and preserve their own reputations for credible financial reporting.     

Outsourcing and Audit Risk for Internal Audit Services*

Some companies now outsource their internal audit function to public accountants. Internal auditors and accounting firms disagree about the merits of outsourcing. Each type of auditor claims to provide more cost‐effective services and appears to claim superior expertise. This paper uses agency theory to examine outsourcing and reconciles the outsourcing debate without resorting to differential auditor expertise. Under the assumptions that public accountants' “deep pockets” provide incentives to outsource and their higher opportunity cost provides a disincentive, we characterize the optimal employment contract with each auditor. We find that public accountants provide higher levels of testing, but possibly for a higher expected fee. This result supports both the internal auditor's claim as the lower cost provider, and the public accountant's claim of higher quality. We also find that incentives to outsource generally increase in various measures of risk, including the risk that a control weakness exists and the size of the loss that can result from an undetected control weakness.     

The Provision of Nonaudit Services by Accounting Firms to their Audit Clients*

Abstract. There has been a strong growth in accounting firms' provisions of nonaudit services to their audit clients. To date, however, there have been few studies into the determinants of this joint provision of audit and nonaudit services. One reason for the paucity of research is the lack of publicly available data with which to empirically examine relationships and test theories. However, recent legislation in the United Kingdom requires publication of nonaudit fees paid to a company's auditor, and this disclosure provides the data with which to investigate the joint provision of consultancy and audit services. A model is developed that seeks to explain a company's decision to hire nonaudit services from the auditor. The model argues that companies that face potentially high agency costs purchase relatively smaller amounts of nonaudit services from their auditor. High agency-cost companies require independent audits in order to reassure investors and creditors; the provision of joint services, which increases the economic bonding of the auditor to the client, may jeopardize independence or the appearance of independence. The model is tested using data observations from 500 companies, and the results indicate that companies that have higher agency-cost proxies are associated with smaller purchases of nonaudit services from their auditors.     

Auditors' Responses to Workload Imbalance and the Impact on Audit Quality*

Using detailed data for fieldwork hours and audit hours by rank from audit engagements in Korea, we examine whether audits conducted under workload imbalance, proxied by busy‐season audits, impair audit quality, and how auditors adjust staff assignments for busy‐season audits. We generally find that busy‐season audits are associated with lower audit quality, and that audit firms reduce the involvement of senior auditors during busy‐season audits. In addition, the greater the involvement of senior auditors and junior auditors, the lesser the deterioration in audit quality. Finally, although there is no increase in interim audits in response to workload imbalance during busy seasons, increasing interim audits can mitigate the negative impact of busy‐season audits on audit quality. Our results are relevant to auditors and regulators, who have expressed concerns about the adverse effects of workload imbalance on audit quality.     

The Impact of R&D Intensity on Demand for Specialist Auditor Services*

The audit fee research literature argues that auditors' costs of developing brand name reputations, including top‐tier designation and recognition for industry specialization, are compensated through audit fee premiums. Audited firms reduce agency costs by engaging high‐quality auditors who monitor the levels and reporting of discretionary expenditures and accruals. In this study we examine whether specialist auditor choice is associated with a particular discretionary expenditure ‐ research and development (R&D). For a large sample of U.S. companies from a range of industries, we find strong evidence that R&D intensity is positively associated with firms' choices of auditors who specialize in auditing R&D contracts. Additionally, we find that R&D intensive firms tend to appoint top‐tier auditors. We use simultaneous equations to control for interrelationships between dependent variables in addition to single‐equation ordinary least squares (OLS) and logistic regression models. Our results are particularly strong in tests using samples of small firms whose auditor choice is not constrained by the need to appoint a top‐tier auditor to ensure the auditor's financial independence from the client.     

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.     

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.     

Auditor Sensitivity to Real Earnings Management: The Importance of Ambiguity and Earnings Context

Differentiating real earnings management (REM) from normal business decisions poses a unique challenge for auditors, researchers, and investors. The ambiguity associated with REM, and the fact that REM does not violate GAAP, may explain why its use is on the rise. While some assert that auditors are not, and should not be, concerned with REM, recent research suggests that REM may influence some auditor judgments. Using Correspondent Inference Theory (CIT) as our theoretical framework, we extend REM research by investigating the ways in which auditors respond to REM and how auditors deal with the intrinsic ambiguity associated with REM. We administer a 3×2 between‐subjects experiment to 113 highly‐experienced auditors, manipulating the level of ambiguity surrounding the observed REM (Explicit REM, Potential REM, or No REM) and the earnings context in which the client engages in REM (the client beat or missed the consensus earnings forecast). We find that auditors respond to REM by lowering assessments of management tone (i.e., management's commitment to a culture of high ethical standards), being more likely to discuss the issue with the audit committee, and being less likely to retain the client. Auditors respond to Explicit REM regardless of the earnings context, but respond to Potential (i.e., ambiguous) REM only when the client beats the forecast. Finally, we find that management tone mediates the relation between REM and auditor responses, even after controlling for various audit‐related risks. Thus, for auditors, REM appears to be primarily a “people” issue, as REM provides a negative signal about management.     

Improving Auditors' Consideration of Evidence Contradicting Management's Estimate Assumptions

Auditors have difficulty evaluating the assumptions underlying management's estimates. One source of these problems is that auditors appear to dismiss evidence contradicting management's assumptions because their initial preference to support management's accounting biases their preliminary conclusions and, thus, their interpretation of evidence. We experimentally examine whether auditors with a balanced focus (i.e., a focus on documenting evidence that supports and contradicts their preliminary conclusion) are less likely to dismiss evidence that contradicts management's assumptions than auditors with a supporting focus (i.e., a focus on documenting evidence that supports their preliminary conclusion). We expect and find that, compared with auditors with a supporting focus, auditors with a balanced focus create documentation that is less dismissive of evidence contradicting management's estimate. Importantly, a balanced focus changes auditors' cognition and affects how auditors interpret contradicting evidence rather than merely increasing their documentation of this evidence. The effects of reduced dismissiveness persist to improve auditors' evaluations of a biased estimate and subsequent actions, improving audit quality in an important and difficult area.     

The Consequences of Audit‐Related Earnings Revisions

In this study, we investigate the consequences that auditors and their clients face when earnings announced in an unaudited earnings release are subsequently revised, presumably as a result of year‐end audit procedures, so that earnings as reported in the 10‐K differ from earnings as previously announced. Specifically, we examine whether the likelihood of an auditor “losing the client” is greater following such revisions, and whether the likelihood of dismissal is influenced by revisions that more negatively impact earnings, that cause the client to miss important earnings benchmarks, by greater local auditor competition, or by auditor characteristics. We also examine audit pricing subsequent to audit‐related earnings revisions for evidence of pricing concessions to retain the client. Finally, we examine whether client executives experience a greater likelihood of turnover following an audit‐related earnings revision. Consistent with expectations, we find that auditor dismissals are more likely following audit‐related earnings revisions. We also find that dismissals are more likely when revisions cause clients to miss important benchmarks and when there is greater local auditor competition. Among nondismissing clients, we find that future audit fees are lower when the effect of the revision on earnings is more negative, consistent with auditors offering price concessions to retain clients when revisions are more displeasing. We also find a greater likelihood of future chief financial officer (CFO) turnover as the effect of the revision worsens. Our findings offer important insights into the consequences that auditors face when balancing their responsibility for high audit quality and client satisfaction, as well as into the consequences that CFOs face when releasing inflated but not fully audited earnings.     

Auditor Face‐Work at the Annual General Meeting

This paper examines how auditors prepare for the annual general meeting (AGM) and how they report their work to the shareholders there. Prior literature has suggested—but not explicitly studied—that the endpoint of an audit is a state of comfort between the auditor and the management and audit committee members, but also is potentially fragile. The fragility can arise from a failure to relay trust to the investor community, which may initiate or increase doubts about the financial report and/or the auditor's independence. We build the case that an AGM is an event to study how the endpoint of an audit engagement is both a state of collective comfort and a fragile state. The analysis is based on ten interviews and three workshops with auditors as well as observations at 67 AGMs. To analyze the field material, the paper draws on Goffman's idea of face‐work, which requires backstage preparations, notably with management, and a front stage performance as an independent auditor to relay trust to the shareholders. The paper details how auditors at the AGM perform as independent verifiers of the management's financial report. Although we recorded that auditors were typically successful in preventing the backstage activities from becoming visible to the shareholders, we found incidents that challenged both the auditors' and the managements' face. In analyzing these incidents, we found that auditors reinforced their image as independent to regain both their own face and the management's face. The management did not take a similar collective responsibility for the auditor's face, which implies that auditors were asymmetrically committed to the management. As a take‐away, the paper discusses how governance mechanisms backstage are linked and can surface front stage at the AGM.     

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.     

The Effect of Joint Auditor Pair Composition on Audit Quality: Evidence from Impairment Tests

Using a sample of firms from France, where the law requires the use of two auditors, we study the effect of auditor pair composition on audit quality by examining a specific account, goodwill impairment. We document that firms audited by a Big 4–non‐Big 4 auditor pair (BS) are more likely to book an impairment and book a larger impairment than firms audited by a Big 4–Big 4 auditor pair (BB) when low‐performance indicators suggest a greater likelihood of impairment. Moreover, firms audited by a BB pair reduce impairment disclosures when they book impairments, while firms audited by a BS pair do not, suggesting lower transparency for firms audited by a BB pair. Our results inform investors and firms in mandatory joint audit regimes, as well as regulators who are considering requiring joint audits.     

The Effect of Audit Quality on Earnings Management*

This study examines the relation between audit quality and earnings management. Consistent with prior research, we treat audit quality as a dichotomous variable and assume that Big Six auditors are of higher quality than non-Big Six auditors. Earnings management is captured by discretionary accruals that are estimated using a cross-sectional version of the Jones 1991 model. Prior literature suggests that auditors are more likely to object to management's accounting choices that increase earnings (as opposed to decrease earnings) and that auditors are more likely to be sued when they are associated with financial statements that overstate earnings (as compared to understate earnings). Therefore, we hypothesize that clients of non-Big Six auditors report discretionary accruals that increase income relatively more than the discretionary accruals reported by clients of Big Six auditors. This hypothesis is supported by evidence from a sample of 10,379 Big Six and 2,179 non-Big Six firm years. Specifically, clients of non-Big Six auditors report discretionary accruals that are, on average, 1.5-2.1 percent of total assets higher than the discretionary accruals reported by clients of Big Six auditors. Also, consistent with earnings management, we find that the mean and median of the absolute value of discretionary accruals are greater for firms with non-Big Six auditors. This result also indicates that lower audit quality is associated with more “accounting flexibility”.     

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.
