Understanding the structure of audit workpaper error knowledge and its relationship with workpaper review performance

This study examines the veracity of two important, yet untested, premises underlying the interpretation of hierarchical variation in workpaper review performance. Prior research has argued that auditors at different hierarchical levels structure their knowledge of workpaper errors differently, and that these differences in knowledge structure give rise to hierarchical variation in the ability of auditors to identify mechanical and conceptual workpaper errors. This study directly examines the way in which audit firm managers, seniors and staff auditors structure their knowledge of audit workpaper errors and finds variation across hierarchical levels. These differences in knowledge structure were found to be associated with variation in workpaper review performance as they related to the identification of conceptual errors, but not, as proposed in prior research, mechanical workpaper errors. These results guide future research efforts aimed at improving workpaper review performance.     

Audit report lag: the role of auditor type and increased competition in the audit market

This study investigates the effect of auditor type (private vs. state) and increased competition in an audit market on audit report lag (ARL). This is the first study to provide evidence regarding the effect of audit market competition on ARL. Utilising structure–conduct–performance theory, we predict that competition pressures private auditors to be more efficient and to have less reporting lag than state auditors. We also predict that competition among auditors after a liberalisation period forces auditors to be more efficient and to record less ARL than before. We use a unique data set in Iran, whereby the audit market liberalisation (an audit market where services were previously provided primarily by a state entity) has resulted in both state and private auditors simultaneously providing audit services. The findings are consistent with the following hypothesis, that is ARL is shorter for private auditors than it is for state auditors, and ARL decreases as competition increases in the Iranian audit market. Consistent with the structure–conduct–performance theory, the findings suggest that increased competition in the audit market results in higher efficiency, as reflected by a shorter ARL.     

Evidence on the Joint Determination of Audit and Non-Audit Fees

In this study we investigate whether the characteristics of clients, auditors, and the auditor‐client relationship simultaneously determine audit and non‐audit fees. As done in prior studies, we maintain that fees proxy for the level of service provided and follow the physical flow of knowledge. Estimating single‐equation models of audit and non‐audit fee models, we confirm prior findings of an association between audit and non‐audit fees. Studies conclude that such evidence is consistent with knowledge spillovers between the two services. However, we document empirically that audit and non‐audit fees are simultaneously determined. Because the data indicate audit and non‐audit fees are jointly determined, we then investigate whether previously documented associations between audit and non‐audit fees are the result of biased estimation induced by using endogenous variables in single‐equation models. In contrast to results from single‐equation estimations, we find no association between audit and non‐audit fees using a simultaneous specification of the fee system, suggesting that single‐equation estimations suffer from simultaneous‐equations bias. In sum, the findings are not consistent with the existence of economies of scope from the joint performance of audit and non‐audit services after controlling for the joint behavior of audit and non‐audit fees. Given the ongoing debate over the level of allowed non‐audit services by auditors, the argument for the joint provision of audit and non‐audit services is less justified than if joint‐supply benefits had been documented.     

Japanese stock market reaction to announcements of news affecting auditors’ reputation: The case of the Olympus fraud

The revelation of accounting fraud by the Olympus Corporation gave rise to shareholder allegations of audit failure against Olympus’ auditors—Ernst & Young ShinNihon LLC and KPMG AZSA LLC—in 2011. In this study, we investigate whether the auditors’ affiliation with Olympus contributes to divergent perceptions of audit quality in the event of news announcements affecting the reputation of Olympus’ auditors. First, we use a nonparametric generalized rank event study methodology on 918 sample firms from the First Section of the Tokyo Stock Exchange (TSE) to observe Japanese investors’ perceptions of auditor reputation as proxied by abnormal returns. Second, we perform a multivariate linear regression on firms’ abnormal returns after controlling for firm-specific variables. We find that Japanese investors do not respond to negative or neutral reputational information arising from news announcements concerning Olympus’ auditors for firms affiliated and not affiliated with those auditors. In the absence of legal penalties imposed on Olympus’ auditors, we argue that Japanese investors consider the Olympus fraud case as an expected occurrence of audit failure due to a lack of evidence suggesting systematic audit failure on the part of Olympus’ auditors and an expectation of lower audit quality in the Japanese capital market. As a result, Japanese investors do not consider news announcements affecting the Olympus auditors’ reputation as sufficient evidence to change their prior expectation regarding the reputations of the audit firms affiliated with the Olympus fraud case.     

An investigation of independent audit opinions and subsequent independent auditor litigation of publicly-traded failed savings and loans

Failures of savings and loans (S & Ls) have resulted in substantial independent auditor litigation; however, there is limited empirical evidence concerning audit opinions of failed S & Ls. Our study investigates the audit opinions of publicly-traded S & Ls that subsequently failed. We found that the independent auditors of failed S & Ls issued qualified (or modified) going-concern opinions or going-concern disclaimers of opinion on the last audited financial statement prior to failure in 19 of 24 cases. Results of univariate and multivariate analyses are consistent with several predictions concerning economic factors expected to influence the type of audit opinion, and our evidence suggests that auditors rendered going-concern reports to those S & Ls that were most likely to fail ex ante. Analysis of independent auditor litigation data reveals that auditor lawsuits related to these failed S & Ls were filed in seven cases. Five of these seven lawsuits implicated auditors who rendered going-concern reports. This suggests that going-concern reports in the year prior to the failure of an S & L do not prevent auditor litigation. Because it is possible that independent auditors will face situations comparable to the S & L crisis in the future, government regulators and the public accounting profession should be interested in research that enhances the understanding of the audit opinion formulation process in such settings.     

Income smoothing and audit fees

In this study, we examine the effect of income smoothing on auditors' pricing decisions. Analyzing a sample of 12,823 firm-year observations from U.S. companies in non-regulated industries for the period 2000–2018, we find that income smoothing is negatively associated with audit fees, suggesting that auditors favorably view smoothed earnings. This result holds when we control for other variables that have been identified as determinants of audit fees in prior literature, including client-specific (e.g., client size, audit complexity, litigation risk, and corporate governance), auditor-specific (e.g., auditor quality, auditor tenure, and auditor expertise), and engagement-specific (e.g., audit opinion, busy season, reporting lag) factors. Our results also hold across (1) alternative smoothing measures (with and without considering the use of accruals to smooth earnings), (2) different sources of income smoothness (innate vs. discretionary components) and (3) various robustness tests. Overall, our evidence supports the notion that auditors perceive income smoothing as signaling rather than opportunistic behavior, and thus charge lower audit fees. To our knowledge, this is the first study that examines income smoothing directly from the perspective of auditors.     

University Audit Departments in the United States

Internal auditors of public and private universities were asked about their selection processes, supervisors, and activities. At public institutions, the governing board selects the internal auditor, the president supervises the work and more audit findings are implemented. Private institutions have more audit committees that are involved with the internal auditors' activities and their auditors perform more program audits. Thus, although public universities are following professional guidelines more closely, suggesting more accountability, private universities have greater access to audit committees and perform more value-added audits.     

Note on Self‐Selection of Auditors in the Municipal Sector*

The objective of this article is to revisit the literature on Big‐N audit fee premiums in the municipal setting using a methodology that controls for self‐selection bias. Because auditor choices can be predicted based on certain client characteristics, using standard one‐stage ordinary least squares regressions to draw inferences about the presence or absence of such a premium in the extant public‐sector audit fee studies may not be appropriate. Results indicate that, after controlling for a self‐selection bias, Big‐6 (non‐Big‐6) municipal clients on average pay a fee premium, compared to the case if they were to retain a non‐Big‐6 (Big‐6) auditor. Results continue to hold when we conduct further analyses on a subset of municipalities with access to both Big‐6 and non‐Big‐6 auditors in a local market defined by a 60‐km radius, rather than over a province‐wide audit market. The existence of non‐Big‐6 audit fee premiums has not been documented previously in the private‐ or public‐sector audit fee literature. We surmise that it may be caused by the dominance (79.4 percent) of non‐Big‐6 auditors in the Ontario municipal market, compared to most private‐sector audit markets where their market share generally does not exceed 20 percent. The strong market position of non‐Big‐6 firms in turn may have allowed these auditors to command a fee premium for the subset of municipalities that self‐selects to be audited by them. An implication from our study is that Ontario municipalities often choose to be audited by more costly auditors, even though they could have paid lower audit fees by switching to an alternative auditor type. These results do not support those reported by Chaney et al. (2004) , who find that U.K. private firms are audited by the least costly auditor type. The conflicting findings may be attributable to the fact that the Ontario municipal audit market is subject to regulation by not just the audit profession but also the Ontario government and that, unlike business corporations, municipalities receive funding from provincial governments to fulfil much of their financial requirements. Thus, municipal clients may be relatively more willing to accept higher audit fees provided their chosen auditor (or auditor type) matches their needs.     

How individual auditor characteristics impact the likelihood of audit failure: Evidence from China

Audit failure imposes a severe loss on investors and damages market participants' confidence in financial reporting quality. This study investigates the impacts of individual auditor characteristics on the likelihood of audit failure. Chinese regulators mandate listed firms to disclose the engagement auditors' identity. Furthermore, the information regarding individual auditor characteristics in China is also publicly available. Utilizing this unique setting, we examine the relationship between individual auditor characteristics and the likelihood of audit failure in China during the period from 2000 to 2009. We document that individual auditors with more auditing experience are less likely associated with audit failure. We also find a weaker negative relationship between auditor education level and audit failure. Our study has important implications for both auditors and regulators by shedding lights on the determinants of audit failure and by providing guidance to the human resource management in audit firms.     

Internal control reporting differences among public and governmental auditors: The case of city and county Circular A-133 audits

We investigate potential differences in audit reporting outcomes between Circular A-133 audits performed by governmental auditors vs. those performed by certified public accounting (CPA) firms. Specifically, we investigate the association between auditor type and the likelihood of auditor-disclosed internal control concerns. We employ a cross-sectional sample of 13,386 single audit reports of US cities and counties during 2004–2006. In contrast to prior literature, the results indicate that in the post-Sarbanes–Oxley environment, CPA firms appear more likely to issue audit reports that identify internal control concerns than are governmental auditors in the context of Circular A-133 audits. The differences are more pronounced for larger CPA firms.     

An Empirical Investigation of the Interface Between Internal and External Auditors

Professional standards place specific responsibilities on auditors for the discovery of material mis-statements in reports of corporate financial performance. Certain factors have been shown to increase the likelihood of fraudulent financial reporting. One warning sign is the potentially pervasive effect of a weak internal control environment consistent with a weak internal audit group. This study investigates the impact of internal audit department quality differences on auditors ‘willingness to place reliance on the work performed by internal auditors. The study also gives consideration to auditors’ recent experiences with material errors and irregularities and examines the influence of two previously untested individual auditor differences on audit judgment decisions: (1) conflict management style and (2) perception of internal/external auditor communication barriers. The results indicate that auditors attend to internal audit department quality differences and that individual auditor differences exhibit significant influence over auditor judgments. Implications for audit practice are considered and directions for future research are suggested.     

Auditor Independence: A Nonparametric Test of Differences Across the Big‐5 Public Accounting Firms

This small sample study provides additional evidence on the unsettled question of auditor independence: Does the provision of non‐audit services by an auditor compromise independence resulting in a poor quality audit? We also examine whether these findings vary across the “Big‐5” public accounting firms. Most prior studies addressing this question, using parametric approaches and various measures of audit quality, have reported conflicting results. Contrary to these studies, we use a non‐parametric approach and the probability of GAAP violation as a new measure of audit quality to address this question. Using data from a sample of Fortune 500 companies for the year 2000, we find that firms whose auditors provide substantial non‐audit services tend to have a higher propensity to violate GAAP. At the firm‐level analysis, we find that these results are more likely driven by few of the Big‐5 public accounting firms. For the remaining firms, the association between non‐audit services and quality of audit could not be established, primarily because of small sample size and lack of power in the test. Our main finding is consistent with other recent studies that provide evidence that the rendering of significant non‐audit services by auditors creates conflict of interest resulting in poor quality audits. Furthermore, our result of differences in these levels of association among the Big‐5 accounting firms represents a new finding, and suggests that there is a need for controlling them separately in research studies examining auditor independence.     

Auditors’ Liability,Investments, and Capital Markets: A Potential Unintended Consequence of the Sarbanes‐Oxley Act

To restore investors’ confidence in the reliability of corporate financial disclosures, the Sarbanes‐Oxley Act of 2002 mandated stricter regulations and arguably increased auditors’ liability. In this paper, we analyze the effects of increased auditor liability on the audit failure rate, the cost of capital, and the level of new investment. We focus on a setting in which, with imperfect auditing, a firm has better information than investors about its prospects and seeks to raise capital for new investments in a lemons market. The equilibrium analysis derives corporate reporting and investing choices by the firm, attestation opinions by the auditor, and valuation by rational investors. Three empirically testable predictions emerge: although increasing auditor liability decreases the audit failure rate and the cost of capital for new projects, it also decreases the level of new profitable investments.     

The effect of auditor IT expertise on internal controls

Material weaknesses in internal controls related to information technology (IT) represent unique threats to organizations. Utilizing the external auditor as an example of an externally observable governance mechanism, we investigate if firms with revealed IT internal control deficiencies employ a strategy of disassociation with their current auditor. Our tests show that prior evidence of disassociation strategies hold in both IT and non-IT contexts. Of particular focus to our study, we document a positive association between firms that report IT material weaknesses and subsequent auditor dismissals or switching. We next investigate the potential internal control benefits of switching to auditors with greater expertise in environments that emphasize the importance of IT. We argue that greater audit firm IT expertise promotes improved internal controls for their clients, especially those controls that are dependent on IT. We find that clients that switch to auditors with greater IT expertise, relative to their former auditor, have a greater likelihood of material weakness remediation within one year of reporting control weaknesses. Complementing these findings, we find that audit IT expertise is negatively associated with both non-IT and IT material weaknesses in an ex ante reporting setting. Prior literature takes a longstanding interest in both the incentive for developing auditor expertise and the effects of that expertise. We contribute to this literature stream by providing additional evidence related to a specific type of expertise.     

Measuring audit quality of local governments in England and Wales

The purpose of this paper is to model and test the audit quality provided to local governments in England and Wales. A key question is: are there major differences in audit quality provided? The Audit Commission, a national public body under Parliament, regulates the audits. It sets audit standards, appoints the auditors, and (although each auditor and client local government set the specific audit fee for that client) it establishes a formula to determine standard audit fees. The Audit Commission also conducts an annual review of the audit quality provided by the selected auditors, as well as a survey of client satisfaction. The majority of audits are conducted by District Auditors (public sector employees of the Audit Commission). About a quarter of local governments are audited by one of six private sector auditors (including three of the Big 4). Actual results indicate that audit quality differences are associated with the number of governmental audit clients and local government type. Generally, there were modest quality differences by auditor category.     

Prompting the Benefit of the Doubt: The Joint Effect of Auditor‐Client Social Bonds and Measurement Uncertainty on Audit Adjustments

We design an incentivized experiment to test whether measurement uncertainty elevates the risk that social bonds between auditors and reporters compromise audit adjustments. Results indicate that, when audit evidence is characterized by some residual uncertainty, the adjustments our auditor‐participants require are sensitive to whether auditors have an opportunity to form a modest but friendly social bond with reporters. In contrast, although auditors do not adjust fully even when misstatements are known with certainty, social bonding has no effect in this scenario. Accordingly, our experiment contributes beyond the main effects of social bonding and measurement uncertainty demonstrated in prior research by showing that these forces interact. A practical implication is that regulators and practitioners should consider both the technical and the social challenges facing audits of complex estimates.     

The Impact of Consulting Services on Audit Quality: An Experimental Approach

We use experimental markets to examine whether providing consulting services to a non‐audit client impacts audit quality. Our paper directly addresses concerns raised by the Public Company Accounting Oversight Board that the largest public accounting firms’ growth in their consulting practices threatens audit quality. We conduct an experiment proposed using a registration‐based editorial process. We compare a baseline where the auditor does not provide consulting services to conditions where auditors provide consulting to audit clients or where auditors only provide consulting services to non‐audit clients. Our unique design provides evidence on whether providing consulting to non‐audit clients strengthens the salience of a client‐cooperative social norm that reduces audit quality. We do not find differences in audit quality by condition in our planned analysis, however we find greater variation in audit quality in the conditions where auditors provide consulting services compared to the baseline. In unplanned analyses, our results suggest providing consulting services increases auditor cooperation with managers, increasing audit quality when managers prefer high audit quality and decreasing audit quality when managers prefer low audit quality.     

Analysts' Cash Flow Forecasts,Audit Effort,and Audit Opinions on Internal Control

We examine the economic impact of analysts’ cash flow forecasts by looking at how external auditors respond to financial analysts’ issuance of cash flow forecasts. Using a differences‐in‐differences approach, we find that financial analysts’ initiation of cash flow forecasts leads to reduced auditor fees and audit report lags. Moreover, after cash flow forecast initiation, firms report fewer Section 404(b) internal control weakness disclosures. These findings suggest that cash flow forecasts constrain earnings manipulation and improve management accounting behavior, thereby reducing inherent and control risk and strengthening firms’ internal control over financial reporting.     

Audit Quality and the Market Valuation of Banks’ Allowance for Loan Losses*

The recent banking crisis has led market participants to focus on the adequacy and quality of banks’ balance sheet items such as the allowance for loan losses. Beaver and Engel (1996) document that the capital market prices the nondiscretionary component of loan loss allowance negatively and the discretionary component less negatively. Using data from the pre‐crisis period and three measures of audit quality, auditor type (i.e., Big 5 versus non–Big 5), auditor industry specialization/expertise, and audit and nonaudit fees paid to auditors, we examine the effect of audit quality on the market valuation of the discretionary component of the allowance for loan losses. We find that, relative to the nondiscretionary component, the market valuation of the discretionary component of loan loss allowance is higher for banks audited by Big 5 auditors than for banks audited by non–Big 5 auditors. We also find that the relative market valuation of the discretionary component of loan loss allowance is increasing in auditor expertise. Regarding the impact of fees paid to auditors, we find that banks paying higher audit fees have higher relative market valuation of the discretionary component of the allowance for loan losses, but banks that pay higher nonaudit fees do not.     

The effect of external audits of internal control over financial reporting on financial reporting for clients of Big 4, Second-tier,and small audit firms

The external audit of internal control over financial reporting (ICFR) is a very expensive and contentious aspect of the Sarbanes–Oxley Act (SOX). Larger public firms were first required to file a management report on and have an external audit of ICFR in 2004. Smaller public firms were first required to file a management report on ICFR in 2007 but are exempt from the audit requirement. Whereas most related prior research investigates the combined effect of management and auditor reports on financial reporting, this study examines the distinct effect of auditor reports on reporting quality. For companies audited by small auditors, we find evidence that financial reporting quality improves with an auditor report on ICFR. We find no evidence that auditor ICFR reports improve reporting quality for clients of Big 4 or Second-tier audit firms. Our study adds to the debate on the applicability of SOX Section 404 to smaller firms.
