The Riskiness of Large Audit Firm Client Portfolios and Changes in Audit Liability Regimes: Evidence from the U.S. Audit Market*

We investigate whether the financial riskiness of large U.S. audit firm clienteles varied with the changing audit litigation liability environment during the period 1975‐99. Partitioning the period of study into four distinct periods (a benchmark period (1975‐84), a period of increasing concerns about litigation liability (1985‐89), a period of lobbying for reform (1990‐94), and a post‐relief period (1995‐99)), we find some evidence of risk decreases during 1985‐89, strong evidence of risk decreases during 1990‐94, and strong evidence of risk increases during 1995‐99. However, we also find that over the period of our study, a time during which Big 6 market shares grew appreciably, the proportion of litigious‐industry clients in Big 6 client portfolios grew at about the same rate as the proportion of such clients in the population. Moreover, the Big 6 share of the financially riskiest clients in the economy did not grow as fast as the overall Big 6 market share. In sum, although our evidence is consistent with the hypothesis that the riskiness of Big 6 client portfolios responded to changes in the audit litigation liability environment, we find no systematic evidence of a "race to the bottom" or "bottom fishing" by these firms in a bid to increase their market shares.     

Audit Qualifications of Income‐Decreasing Accounting Choices*

In this study we conduct an experiment to examine how qualifying an income‐decreasing accounting change in years of strong financial performance affects financial report users' assessments of strategic reporting, current financial performance, and future financial performance (performance over the next three years). We find that without the qualification, users viewed the income‐decreasing accounting change as relatively nonstrategic and that user assessments of current and future performance were not different. In the presence of the qualification, users believed that the accounting change was relatively strategic, and they discounted the income effect of the accounting change. We find further that their assessments of future performance were below their assessments of current performance but no different from the assessments of future performance in the absence of the qualification. Although our findings suggest that audit qualifications encourage users to be skeptical of income‐decreasing accounting changes, we find no evidence that they impose negative consequences on management in terms of lower assessments of financial performance.     

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.     

Audit Strategies and Multiple Fraud Opportunities of Misreporting and Defalcation*

We examine how an auditor assesses the risk of fraud and formulates an audit plan when the auditee has the opportunity to commit various types of fraud. Unlike previous studies, the audi‐tee can misappropriate assets (defalcation), misreport financial information (fraudulent financial reporting), or misreport financial information in combination with defalcation. Our results identify four possible equilibria whose characteristics depend on the auditee's relative rewards and penalties from the various types of fraud, the cost of audit effort, and expectations about the auditee‐firm's performance. When the cost of audit effort is sufficiently small, fraud risk assessment depends on the auditee's rewards and penalties associated with each type of fraud, but not on the auditor's beliefs about firm performance. The auditor develops an audit plan that focuses on the type of fraud the auditee is most motivated to commit, and in turn, the audit plan deters all other types of fraud.     

Audit Firm Tenure,Bank Complexity,and Financial Reporting Quality

Theory from organizations and economics research posits that in an inter‐organizational relationship, both parties invest in relationship‐specific knowledge, which in turn facilitates the effectiveness of the relationship while strengthening the attachment between the parties. In complex settings where there are more opportunities for knowledge creation, the investments will be larger and the attachment stronger. Because banks are complex institutions that present unique challenges to auditors, we suggest that effective audits critically depend on the accumulation of significant investments in client‐specific expertise through a long association with the client. We find a positive association between audit firm tenure and financial reporting quality, and this association is particularly strong in banks that are more complex. Also, contrary to recent research we find that benefits of audit firm tenure for complex banks accrue even for long tenure and are not limited to medium tenure. Our findings largely support the notion that a long relationship with the client reflects the underlying demand for expertise, which is critical for high‐quality audits of complex organizations. Imposing short‐term limits on audit firms would adversely affect the investments in client‐specific expertise especially in the cases where this expertise is needed the most. Our findings do not support calls for mandatory audit firm rotation for large complex institutions.     

Auditor Choice and Its Implications for Group‐Affiliated Firms

We examine which of two opposing financial reporting incentives that group‐affiliated firms experience shapes their accounting transparency evident in auditor choice. In one direction, complex group structure and intragroup transactions enable controlling shareholders to pursue diversionary activities that they later hide by distorting reported earnings. In the other direction, as outside investors price‐protect against potential expropriation, controlling shareholders may be eager to improve financial reporting quality in order to alleviate agency costs. To empirically clarify whether group affiliation affects company insiders' incentives to address minority shareholders' concerns over agency costs, we examine auditor selection of group firms relative to stand‐alone firms. In comparison to nongroup firms, our evidence implies that group firms are more likely to appoint Top 10 audit firms in China, especially when their controlling shareholders have stronger incentives to improve external monitoring of the financial reporting process. After isolating group firms, we find that the presence of a Top 10 auditor translates into higher earnings and disclosure quality, higher valuation implications for related‐party transactions, and cheaper equity financing, implying that these firms benefit from engaging a high‐quality auditor. In additional analysis consistent with our predictions, we find that group firms that are Top 10 clients pay higher audit fees and their controlling shareholders are more constrained against meeting earnings benchmarks through intragroup transactions and siphoning corporate resources at the expense of minority investors. Collectively, our evidence supports the narrative that insiders in firms belonging to business groups weigh the costs and benefits stemming from auditor choice.     

Impact of Auditor Report Changes on Financial Reporting Quality and Audit Costs: Evidence from the United Kingdom

While substantial revisions to auditor reporting requirements are being implemented internationally, the impact of these reforms on financial reporting quality is unknown. We exploit the United Kingdom's recent auditor reporting changes and find that the United Kingdom's new reporting regime is associated with an improvement in financial reporting quality as proxied by significant decreases in absolute abnormal accruals and the propensity to just meet or beat analyst forecasts, and a significant increase in earnings response coefficients. As for audit costs, we do not find a significant change in audit fees or audit delay surrounding the implementation of the new reporting regime. Taken together, the results of this study suggest that new auditor reporting requirements are associated with a significant improvement in financial reporting quality without detecting a significant increase in audit costs.     

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.     

Spillover Effects of Internal Control Weakness Disclosures: The Role of Audit Committees and Board Connections

We find that firms are less likely to report an internal control material weakness (as mandated by the Sarbanes‐Oxley Act) in a given year if one of their audit committee members is concurrently on the board of a firm that disclosed a material weakness within the prior three years. We find a similar spillover effect for financial restatement disclosures. The spillover from material weakness disclosures is evident only if a shared director has more experience with the disclosing firm or can channel more information about the disclosed material weakness. Our findings suggest that prior director experiences outside the firm influence the work of audit committees inside the firm. One rationale is that a director's prior experience with an adverse disclosure helps diffuse important insights and serves as a catalyst for improvements in a firm's internal control and financial reporting practices. An alternative explanation, which we cannot dismiss, holds that a director's prior experience helps a firm to underreport material weaknesses and financial restatements without any attendant improvements in the underlying practices.     

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.     

Internal Control and Operational Efficiency

In this study, we examine whether internal control over financial reporting affects firm operational efficiency. We find that operational efficiency, derived from frontier analysis, is significantly lower among firms with material weaknesses in internal control relative to firms without such weaknesses. We also find that the remediation of material weaknesses leads to an improvement in operational efficiency. Additional analyses indicate that the negative effect of material weaknesses on operational efficiency is stronger for firms with a greater demand for higher quality information for decision making, for weaknesses that are deemed to be more severe, and to a certain extent, for smaller firms. Overall, our study extends the literature by presenting systematic evidence on the effect of effective internal control on operational efficiency and informs the debate over the costs and benefits of the internal control reporting requirements under the Sarbanes‐Oxley Act of 2002.     

An Incomplete Audit at the Earnings Announcement: Implications for Financial Reporting Quality and the Market's Response to Earnings

There has been a substantial increase, since 2004, in the number of firms that announce annual earnings before audit completion as opposed to after audit completion. In this study, we argue that earnings announced before audit completion are associated with lower financial reporting quality and investor perceptions that earnings are more likely to be overstated. Consistent with this expectation, we document that the market places more (less) weight on good (bad) earnings news for earnings announced after audit completion relative to earnings announced before audit completion. We continue to find this differential market response when we expand the returns window to include the 10‐K filing date, suggesting that the differential response is not driven by investors' temporary concerns about earnings revisions between the earnings announcement and the 10‐K filing date or by differential GAAP disclosures in the earnings announcement, as suggested in prior research. Finally, as a direct test of financial reporting quality, we show that earnings announced with a completed audit are less likely to be restated in the future, are less likely to meet or beat expectations, and are associated with fewer income‐increasing discretionary accruals than those announced with an incomplete audit.     

Brand Name Audit Pricing,Industry Specialization,and Leadership Premiums post‐Big 8 and Big 6 Mergers*

This paper investigates brand name, industry specialization, and leadership audit pricing in the wake of the mergers that created the Big 6 and the Big 5 accounting firms. For samples of Australian listed public companies in each of the postmerger years 1990, 1992, 1994, and 1998, we estimate national audit fee premiums for the Big 6/5 auditors and the industry specialists and leaders. We find limited support for the ability of the Big 6/5 to obtain fee premiums over non‐Big 6/5 for those industries not having specialist auditors. Nonspecialist Big 6/5 auditors are able to obtain fee premiums over nonspecialist non‐Big 6/5 auditors for those industries having specialist auditors. However, this result only holds among the smaller half of our sample. We do not find strong support for the presence of industry specialist premiums in the postmerger years, especially after 1990, using various definitions of industry specialist. We find, at best, limited support for the presence of industry leadership premiums. The evidence suggests that after the Big 8/6 audit firm mergers, some caution is required in generalizing the Craswell, Francis, and Taylor 1995 finding of national market industry specialist premiums. More generally, the study raises questions about the tenuous link between the concept of specialization and national market‐share statistics.     

Audit Committees,Boards, and the Quality of Reported Earnings*

I use data on 252 U.S. firms between 1994 and 2000 to study the relationship between audit committees and boards of directors with financial reporting quality. I initially document several changes in committee and board profile during the sample period. Results from logistic regressions suggest that measures of audit committee and board structure are related to earnings quality in a manner that is generally consistent with the predictions of agency theory. This study contributes to extant knowledge by employing different earnings quality measures from prior studies, and by expanding the range of audit committee attributes deemed important in determining audit committee performance.     

The Relationship between Board Characteristics and Voluntary Improvements in Audit Committee Composition and Experience*

This study empirically examines the relation between certain board of director characteristics and the extent that audit committee composition voluntarily exceeds minimum mandated levels and includes outside directors with financial reporting and audit committee knowledge and experience. This study focuses on board characteristics because the board directly controls audit committee membership. Such staffing decisions can directly affect the ability of the audit committee to monitor management's financial reporting process on behalf of the board. Results suggest that Canadian firms that voluntarily include more outside directors on the audit committee than the mandated minimum have larger boards with more outsiders serving on those boards and are more likely to segregate the board chairperson position from the CEO/president positions. Additionally, firms that voluntarily create audit committees composed of outsider members with a breadth of relevant financial reporting and audit committee knowledge and experience have boards that are larger, have more outside members, and are less likely to be chaired by the CEO/president. Implications of these findings for auditors, institutional investors, regulators, and other interested parties are discussed.     

Auditor Reporting and Regulatory Sanctions in the Broker‐Dealer Industry: From Self‐Regulation to PCAOB Oversight

The financial security of the investing public relies on high‐quality service by broker‐dealers (BDs), investors' gateway to the financial markets. The SEC has long required auditors to attest to BDs' internal controls and compliance with regulations (including those privately owned). Following the unraveling of the Madoff Ponzi scheme in 2008, the SEC required auditors of all BDs to register with the PCAOB, and Congressional initiatives signaled imminent transition from private (AICPA) to public (PCAOB) oversight. We investigate whether audit quality increased following this transition by measuring whether auditors report material internal control and compliance problems for BD clients where a deficiency presumably existed (i.e., BDs sanctioned by the Financial Industry Regulatory Authority for transgressions against stakeholders). Overall, we do not find increased reporting quality following the regulatory shift but do observe variation by auditor group and BD ownership. While reporting quality for global network firms (GNFs) increases slightly, lower reporting quality observed prior to the regulatory shift for specialist audit firms (having large BD portfolios but small overall size) is exacerbated afterward. This finding complements results of PCAOB inspections and other research identifying audit quality problems among small, industry‐specialized firms in non‐public client settings. Focusing on deficiencies likely more difficult to detect, we find lower reporting quality for private relative to publicly affiliated BDs prior to PCAOB oversight, and lower reporting quality for very small audit firms relative to GNFs following the regulatory shift.     

The Interrelation between Audit Quality and Managerial Reporting Choices and Its Effects on Financial Reporting Quality

Two distinct lines of research have been dedicated to empirically testing how financial reporting quality (measured as the earnings response coefficient or ERC) is associated with management's choice of reporting bias and with audit quality. However, researchers have yet to consider how ERCs are affected by either the auditor's reaction to changes in the manager's reporting bias or the manager's reaction to changes in audit quality. Our study provides theoretical guidance on these interrelations and how changes in the manager's or the auditor's incentives affect both reporting bias and audit quality. Specifically, when the manager's cost (benefit) of reporting bias increases (decreases), we find that expected bias decreases, inducing the auditor to react by reducing audit quality. Because we also find that the association between expected audit quality and ERCs is always positive, changes in managerial incentives for biased reporting lead to a positive association between ERCs and expected reporting bias. When the cost of auditing decreases or the cost of auditor liability increases, we find that expected audit quality increases, inducing the manager to react by decreasing reporting bias. In this case, changes in the costs of audit quality lead to a negative association between ERCs and expected reporting bias. Finally, we demonstrate the impact of our theoretical findings by focusing on the empirical observations documented in the extant literature on managerial ownership and accounting expertise on the audit committee. In light of our framework, we provide new interpretations of these empirical observations and new predictions for future research.     

An Experimental Investigation of Approaches to Audit Decision Making: An Evaluation Using Systems‐Mediated Mental Models*

The objective of this research is to articulate a decision‐making foundation for the systems audit approach. Under this audit approach, the auditor first gains an understanding of the auditee's economic environment, strategy, and business processes and then forms expectations about its performance and financial reporting. Proponents of this audit approach argue that decision making is enhanced because the knowledge of the system allows the auditor to focus on the most important risks. However, there has not been an explicit framework to explain how systems knowledge can enhance decision making. To provide such a framework, we combine mental model theory with general systems theory to produce a hypothesis we refer to as a systems‐mediated mental model hypothesis. We test this hypothesis using experimental economics methods. We find that (1) subjects make systematic errors under the setting without an organizing framework provided by the systems information, and (2) the presence of an organizing framework results in lower reporting errors. Importantly, the organizing framework significantly enhances decision making in the settings where the environment changed. Establishing a decision‐making foundation for systems audits can provide an important building block that, in part, can contribute to the development of a more effective and efficient audit technology ‐ an important objective now when audits are facing a credibility crisis.     

Board Characteristics and Audit Fees*

This paper examines the relations between three board characteristics (independence, diligence, and expertise) and Big 6 audit fees for Fortune 1000 companies. To protect its reputation capital, avoid legal liability, and promote shareholder interests, a more independent, diligent, and expert board may demand differentially higher audit quality (greater assurance, which requires more audit work) than the Big 6 audit firms normally provide. The audit fee increases as the auditor's additional costs are passed on to the client, such that we expect positive relations between audit fees and the board characteristics examined. We find significant positive relations between audit fees and board independence, diligence, and expertise. The results persist when similar measures of audit committee “quality” are included in the model. The results add to the growing body of literature documenting relations between corporate governance mechanisms and various facets of the financial reporting and audit processes, as well as to our understanding of the determinants of audit fees.     

Audit Partner Tenure and Internal Control Reporting Quality: U.S. Evidence from the Not‐For‐Profit Sector

This study examines the effects of audit partner tenure and audit partner changes on internal control reporting quality for large U.S. not‐for‐profit (NFP) organizations. Regulators contend that audit partners lose their objectivity over successive audits, reducing audit quality. A large body of research has examined this issue, primarily in non‐U.S. jurisdictions, with mixed results. We examine the associations between audit partner tenure and audit partner changes and the incidence of reported internal control deficiencies (ICDs), the quality of internal control reports (following PCAOB audit quality indicators), and the severity of reported ICDs. We find negative associations between audit partner tenure and the incidence of reported ICDs, the quality of internal control reports, and the severity of reported ICDs. Together, these findings indicate that internal control reporting quality deteriorates with audit partner tenure. However, we find no association between audit partner changes and internal control reporting, which is consistent with partners lacking client specific knowledge in their first year with a client. Finally, we find no association between either audit partner tenure or changes and the likelihood of remediation. Our findings contribute large‐sample U.S. evidence on the association between audit partner tenure and internal control reporting quality and provide useful information to government regulators, NFP boards charged with the oversight of the external auditor and internal controls, and NFP stakeholders.
