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.     

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.     

Dividend Policy at Firms Accused of Accounting Fraud

Recent studies and some policy experts have posited that dividends indicate higher‐quality earnings. In this study, we test this conjecture by comparing the dividend policies of firms accused of accounting fraud to those of firms not accused of accounting fraud. Specifically, we examine whether alleged fraud firms are as likely to be dividend payers as non‐fraud firms, and whether managers of dividend‐paying fraud firms increase dividends at the same rate as managers of non‐fraud firms. Our data reveal that dividend paying status is negatively associated with the probability of committing accounting fraud. In addition, we also find that, during the alleged fraud period, the earnings–dividends relation is weaker for the alleged fraud firms relative to firms not accused of fraud. Finally, using propensity score match tests, the data provide evidence that managers of alleged fraud firms increase dividends less often than managers of firms not accused of fraud, consistent with the alleged fraud firms not being able to match the dividend policies of firms not accused of fraud. Overall, our results suggest that dividends, especially dividend increases, are associated with higher earnings quality.     

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”.     

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.     

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.     

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.     

Auditor Fees and Fraud Firms

The issue of whether auditor fees affect auditor independence has been extensively debated by regulators, investors, investment professionals, auditors, and researchers. The revised Securities and Exchange Commission (SEC) requirements that resulted from the implementation of the Sarbanes‐Oxley Act (2002) limit nonaudit services (NAS) and mandate NAS fee disclosure. The SEC's requirements are based on the argument that auditor independence could be impaired—and hence audit quality may be reduced—when auditors become economically dependent on their clients or audit their own work. Economic bonding leads to reduced independence, which can lead to reduced audit quality. We study a sample of firms sanctioned by the SEC for fraudulent financial reporting in Accounting and Auditing Enforcement Releases (SEC‐sanctioned fraud firms) and examine whether there is a relationship between auditor fee variables and the likelihood of being sanctioned by the SEC for fraud. We use SEC sanction as a measure of audit quality that has not previously been used in the auditor fee literature and is more precise than some of the other proxies used for flawed financial/auditor reporting. We find, in univariate tests, that fraud firms paid significantly higher (total, audit, and NAS) fees. However, in multivariate tests, when controlling for other fraud determinants and endogeneity among the fraud, NAS, and audit fee variables, we find that while NAS fees and total fees are positively and significantly related to the likelihood of being sanctioned by the SEC for fraud, audit fees are not. These findings suggest that higher NAS fees may cause economic bonding, thereby leading to reduced audit quality. Our findings of significantly higher NAS fees and total fees in fraud firms hold after controlling for latent size effects and other rigorous testing. These results contribute to the literature that examines the SEC's concerns regarding NAS and can be used by policy makers for additional consideration.     

The Influence of Nonaudit Service Revenues and Client Pressure on External Auditors' Decisions to Rely on Internal Audit*

This paper investigates how external auditor provision of significant nonaudit services and client pressure to use the work of internal audit influence external auditors' use of internal auditors' work. More specifically, we study how external audit evidence gathering choices are influenced by nonaudit fees and client pressure. Our research is motivated by an observation that the magnitude of nonaudit services provided to audit clients introduces the risk that client management may leverage its position with the external auditor and potentially affect the audit process. We address this issue by extending prior research and focusing on the importance of various explanatory variables, including nonaudit service revenues, client pressure, internal audit quality, and coordination, to the external auditor's decision to rely on the work of internal audit. We use data primarily obtained through surveys completed by internal and external auditors. The survey responses represent 74 separate audit engagements. Our findings reveal that when significant nonaudit services are not provided to a client, internal audit quality and the level of internal‐external auditor coordination positively affect auditors' internal audit reliance decisions. However, when the auditor provides significant nonaudit services to the client, internal audit quality and the extent of internal ‐ external auditor coordination do not significantly affect auditors' reliance decisions. Furthermore, when significant nonaudit services are provided, client pressure significantly increases the extent of internal audit reliance. Thus, external auditors appear to be more affected by client pressure and less concerned about internal audit quality and coordination when making internal audit reliance decisions at clients for whom significant nonaudit services are also provided.     

Did Houston Clients of Arthur Andersen Recognize Publicly Available Bad News in a Timely Fashion?*

Despite the allegations of audit failure and the enormous publicity surrounding Arthur Andersen's indictment, there is no systematic empirical evidence on characteristics of accounting information of clients of Arthur Andersen vis‐à‐vis other Big 6 auditors. I examine whether earnings of Andersen's Houston‐based clients are timely in reporting bad news about future cash flows. I find that relative to a control group consisting of Houston‐based clients audited by other Big 6 auditors, earnings of Andersen clients are less timely in reporting bad news. Further, it appears that operating accruals of Andersen clients are less effective in accelerating the timely recognition of bad news than operating accruals of non‐Andersen clients. The findings suggest that the clients of Andersen's Houston office engaged in aggressive accounting practices, including delayed recognition of publicly available bad news.     

Are Auditors Compromised by Nonaudit Services? Assessing the Evidence*

Ruddock, Taylor, and Taylor (2006) use an earnings conservatism framework to investigate the effects of nonaudit services (NAS) on earnings conservatism, and to test whether audit quality was impaired by NAS in Australia during the 1990s. They find no evidence of differential conservatism conditional on the level of NAS fees paid to auditors, and thus conclude that NAS have no adverse effect on audit quality. While this result may not extrapolate to the U.S. setting due to institutional difference between the two countries, the study does add to a growing body of empirical evidence that questions whether there is any logical rationale for restricting the scope of the services that auditors provide to their audit clients. In reviewing the NAS research literature over the past 40 years, one has to conclude that there is no “smoking gun” evidence linking the provision of nonaudit services with audit failures. However, the literature also finds that NAS can adversely affect the appearance of auditor independence, and this may be more than a “mere perception” problem, because there is also evidence that stock prices are significantly lower for companies that pay their auditors large fees for nonaudit services.     

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.     

“金税三期”税收征管对上市公司审计费用的影响

税收征管作为公司外部治理手段,能够作用于公司经营环节,进而影响审计师面临的业务风险和审计风险,由此影响到公司的审计费用。但目前鲜有文献研究税收征管对公司审计费用的影响。本文借助"金税三期"工程这一"准自然实验",以2010—2019年A股上市公司为样本并使用双重差分法,研究发现"金税三期"工程提高了上市公司的审计费用。机制分析表明,"金税三期"工程推高了上市公司实际税率,降低了上市公司的盈利水平,提高了审计师的业务风险,进而提高了审计费用。同时,"金税三期"工程强化涉税信息监管,提高了上市公司会计信息质量,降低了审计师的审计风险,从而降低了审计费用。综合来看前者对审计费用的影响大于后者,导致了上市公司审计费用的提高。进一步分析发现,"金税三期"工程对审计费用的这一影响,在非国有上市公司和由非国际四大会计师事务所审计的上市公司中更为显著。     

Auditor Quality and the Accuracy of Management Earnings Forecasts*

In this study, we appeal to insights and results from Davidson and Neu 1993 and McConomy 1998 to motivate empirical analyses designed to gain a better understanding of the relationship between auditor quality and forecast accuracy. We extend and refine Davidson and Neu's analysis of this relationship by introducing additional controls for business risk and by considering data from two distinct time periods: one in which the audit firm's responsibility respecting the earnings forecast was to provide review‐level assurance, and one in which its responsibility was to provide audit‐level assurance. Our sample data consist of Toronto Stock Exchange (TSE) initial public offerings (IPOs). The earnings forecast we consider is the one‐year‐ahead management earnings forecast included in the IPO offering prospectus. The results suggest that after the additional controls for business risk are introduced, the relationship between forecast accuracy and auditor quality for the review‐level assurance period is no longer significant. The results also indicate that the shift in regimes alters the fundamental nature of the relationship. Using data from the audit‐level assurance regime, we find a negative and significant relationship between forecast accuracy and auditor quality (i.e., we find Big 6 auditors to be associated with smaller absolute forecast errors than non‐Big 6 auditors), and further, that the difference in the relationship between the two regimes is statistically significant.     

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.     

Audit Hours and Unit Audit Price of Industry Specialist Auditors: Evidence from Korea

Higher audit fees associated with auditor industry specialization could represent higher unit price charged by industry specialist auditors (ISAs) or the provision of a greater quantity of audit services. This study exploits a field setting in Korea, where the disclosure of audit hours is required in company annual reports, and finds that ISAs charge significantly higher total audit fees but also expend significantly greater audit hours than non‐ISAs. When audit fees and hours are considered together, the unit audit price of ISAs is significantly lower than that of non‐ISAs. This indicates that higher total audit fees associated with ISAs are likely to be attributable to greater audit hours associated with ISAs. However, greater audit hours for ISAs may suggest higher audit quality or may simply indicate that the additional audit work performed by ISAs is conducted by relatively cheaper junior auditors. Our work provides an alternative explanation for the higher total audit fees documented in the previous studies.     

Market Structure and Audit Fees: A Local Analysis*

This study conducts a local analysis of the relation between market structure and audit fees. The research question of interest to us is how audit fees are determined by each practicing local office, after taking into account the auditor's own position in a local market and the influence exerted by his or her clients. Appealing to the economic theories of monopoly and monopsony power, we hypothesize a positive audit fee‐concentration relation, and a negative audit fee‐client influence relation. Results indicate that auditor market concentration is positively associated with the non‐Big 6 audit fees but is unrelated to the Big 6 audit fees. Evidence is mixed concerning the client influence hypothesis. When this construct is proxied by the number of rival auditors operating within a geographic area centered on the municipality, the prediction of negative audit fee‐client influence relation is strongly supported for both groups of auditors. Results are much weaker using measures developed based on the relative importance of a municipal client to its auditor's audit portfolio. The issues addressed in this study are important at a time when the Canadian municipal sector is undergoing major changes because of municipal amalgamation, altering the underlying market structure for audit services and the bargaining position of a municipality vis‐Ã‐vis its auditor. More broadly speaking, our analysis implies that when assessing an auditor's report for signs of client pressure, the professional oversight bodies and regulatory authorities need to consider the relative, rather than the absolute, bargaining position of the client in question.     

Future Nonaudit Service Fees and Audit Quality

Prior to the Sarbanes–Oxley Act of 2002, audit partners experienced economic pressure to grow revenue from the sale of nonaudit services to their audit clients. To an auditor who is highly rewarded for revenue generation and growth, nonaudit services may represent a particularly strengthened economic bond with the client. Prior research shows that, in general, nonaudit service fees received in the current period do not impair audit quality. We examine a different setting. We propose that auditor independence can become impaired, and audit quality compromised, when clients that currently purchase relatively low amounts of nonaudit services, increase their purchases of nonaudit services from the auditor in the subsequent period. We test our prediction in the context of earnings management as a proxy for audit quality, measured by (a) performance‐adjusted discretionary accruals and (b) classification shifting of core expenses. Our results indicate that prior to the Sarbanes‐Oxley Act, rewards to the auditor in the form of future additional nonaudit service fees from current‐year high fee‐growth‐opportunity clients adversely affects audit quality. This effect is particularly strong among companies with powerful incentives to manage earnings. Our findings indicate that regulators should consider the multiperiod nature of the client–auditor relationship when contemplating policies that restrict nonaudit services, as well as the overall environment in which audit partners operate. This might include partner compensation arrangements that put pressure on audit partners to focus on increasing revenue at the expense of audit quality.     

Dividend Stickiness,Debt Covenants,and Earnings Management

Consistent with the notion that dividends are very sticky, Daniel, Denis, and Naveen ( 2008 ) report evidence that firms manage earnings upward when pre‐managed earnings are expected to fall short of dividend payments. However, we find that this evidence is not robust when controlling for firms' tendency to manage earnings upward to avoid reporting earnings declines; only firms with high leverage exhibit a statistically weak tendency to manage earnings to close deficits of pre‐managed earnings relative to dividends. We further report that the decision to cut dividends depends on whether reported earnings fall short of past dividends, but not on earnings management that eliminates a shortfall in pre‐managed earnings relative to dividend payments. Overall, our evidence suggests that firms that face dividend constraints are more likely to cut dividends than to manage earnings to avoid dividend cuts.     

Nonaudit Services and Earnings Conservatism: Is Auditor Independence Impaired?*

We examine whether the provision of nonaudit services (NAS) by incumbent auditors is associated with a reduction in the extent to which earnings reflect bad news on a timely basis (that is, news‐based conservatism). Reduced conservatism is expected to occur if relatively high levels of NAS result in reduced auditor independence and, ultimately, lower‐quality auditing. Because client‐specific demand for NAS is expected to vary, our proxy for the auditor‐client economic bond is the extent to which NAS purchases (relative to audit fees) are greater or less than expected. Using several different methods for identifying news‐based conservatism, we consistently find that higher than expected levels of NAS are not associated with reduced conservatism. This result is robust to allowing for endogenous NAS demand, as well as several explicit factors that may be associated with differences in conservatism. Similar conclusions arise from tests that use alternative measures of the economic bond between auditors and their clients, as well as in tests confined to either the Big 6 or non‐Big 6 audit firms. Our results are consistent with factors such as market‐based incentives, the threat of litigation, and alternative governance mechanisms offsetting any expected benefits to the audit firm from reducing its independence. We therefore conclude that recent legislative intervention aimed at restricting the supply of NAS is unlikely to result in increased independence in fact, although independence in appearance may be improved.
