The impact of audit penalty distributions on the detection and frequency of fraudulent reporting

We investigate how the distribution of the penalties incurred by auditors for failing to detect fraud influences their effort to detect fraud and auditees’ commission of fraud. We compare a probabilistic, skewed audit penalty to a penalty that automatically imposes the expected penalty of the probabilistic distribution (hereafter, a deterministic penalty). Our experiments show that a deterministic penalty with the same expected value of a probabilistic, skewed penalty increases audit effort to detect fraud and decreases fraudulent reporting by auditees and that these benefits hold in a game involving both auditee and auditor players.     

Audit Labor Usage and Fees under Business Risk Auditing

The adoption of business risk audit (BRA) approaches during the 1990s by several leading audit firms has been the subject of considerable scrutiny and commentary. Under BRA, the auditor responds to the increasing complexity of auditee financial reports by acquiring a deep and comprehensive understanding of the auditee's industry, strategy, business models, and processes—tasks best accomplished by higher-ranked labor—and by employing this understanding to make audit labor allocations. Using proprietary data for 165 audits conducted in 2002, we investigate three propositions about audit labor use under BRA. First, relative to pre-BRA benchmarks for the same auditor, we expect BRA audits to use a greater proportion of higher-ranked labor. Second, we expect engagements with high assessed auditor business risk (ABR), a summary risk assessment that reflects the BRA auditor's rich understanding of the auditee, to be allocated more labor and more higher-ranked labor than pre-BRA benchmarks. Third, at all ranks of labor, we expect a positive association between assessed ABR and levels of labor use. We find empirical evidence consistent with these propositions. We also find that total labor use in our sample is only modestly lower than pre-BRA norms. Analysis of fee data from these engagements suggests that audit fees in 2002 are substantially less than would be expected under pre-BRA benchmarks. After controlling for audit labor use, both total fees and fees per hour increase with assessed ABR for first-year auditees but not for continuing auditees. Overall, our results provide evidence on the impact of the BRA audit regime and speak to the likely impact of BRA on audit effectiveness and efficiency.     

The role of audit evidence in a strategic audit

This study examines how audit risk (the probability of false acceptance) and its components change when the auditor obtains audit evidence in an acceptance sampling model. Inherent risk and audit risk increase with audit evidence if the auditee has a sufficiently strong incentive for committing fraud. Detection risk always increases when audit evidence is introduced. If the auditor has a sufficiently strong incentive for avoiding false rejection, audit risk also increases with audit evidence. The analysis indicates that requiring auditors to obtain information is not effective in preventing material misstatements in at least some instances.     

The Regulation of Public Company Auditing: Evidence from the Transition to AS5

The replacement of Auditing Standard No. 2 (AS2) by Auditing Standard No. 5 (AS5) creates a natural experiment that sheds light on (1) potential inefficiencies caused by regulatory responses to a political crisis and (2) audit efficiency and effectiveness improvements resulting from the risk‐based approach embodied in AS5. We study these effects by examining the impact of AS5 on audit fees. We find that AS5 audit fees are aligned with auditee fraud risk, but not AS2 audit fees. Second, relative to AS2 benchmark levels, AS5 audit fees are, on average, lower for all auditees. Third, relative to AS2 benchmarks, AS5 fees are lower for lower‐fraud‐risk auditees but greater for higher‐fraud‐risk auditees. Overall, the evidence is consistent with (1) initial overregulation (via AS2) followed by reform (via AS5) and (2) auditors deploying a risk‐based audit approach to obtain both efficiency and potential effectiveness gains in audit production.     

GAME THEORY AND THE AUDITOR'S PENALTY REGIME

This paper models the audit as a cooperative game played by the auditor and auditee within a penalty regime imposed by a regulatory authority. The paper investigates the relationship between the penalties set by the regulator and the jointly agreed strategy of the auditor and auditee, and discusses how the penalty regime might be employed so as to induce a particular strategic outcome such as high effort levels on the part of the auditee and/or auditor.     

Management letter comments: Their determinants and their association with financial reporting quality in local government

The issuance of management letters (MLs) as part of financial statement audits is a long-standing practice; however, previous studies of MLs are few and no previous research has tested the utility of MLs empirically. This paper reports a study of MLs issued by independent CPA firms pursuant to audits of Florida general purpose local governments. We investigate the determinants of ML comments, finding that such comments are influenced by auditee characteristics and auditor tenure but not by auditor specialization, a proxy for audit quality. Further, we explore the relationship between MLs and financial reporting quality. We observe a negative relationship between first-year ML comments and assessed financial reporting quality. When lagged one year, first-year ML comments bear a positive relationship with financial reporting quality. The absence of ML comments is positively associated with financial reporting quality. Our results suggest that MLs are beneficial to auditees. As such, our study should be interesting to policymakers, users of financial reports, auditees, and auditors.

DETERMINANTS OF AUDIT FEES FOR QUOTED UK COMPANIES

This study reports further evidence as to the determinants of the audit fees paid by quoted companies in the UK. It outlines a framework based on the findings from semi-structured interviews with partners in four large audit firms and the results of previous research, and tests this framework by means of multivariate analysis using 1987 data for a large sample of quoted UK companies. A model explaining 87 per cent of the variation in audit fees is constructed. The principal explanatory variables are found to be auditee size, return on shareholders equity, the number of subsidiaries, the lag between the year end and the date of the audit report, the size of the auditor, a measure of auditee diversification, the ownership structure of the auditee, and whether the auditor was based in London, with the last three being new variables introduced in this study.     

Regulating the Market for Audit Services: A Game Theoretic Approach

We apply game theory to model how alternative mandatory audit firm rotation regimes can affect the strategic interaction between auditee and auditor firms, and analyze potential consequences on detection risk and impairment of auditor scepticism. The major results suggest that: (1) relative to an initial state with no rotation requirement but high probability for impaired auditor scepticism, imposing either short-term or long-term mandatory audit firm rotation will remove the threat to auditor scepticism and lead to higher audit fees and lower detection risk; (2) relative to long-term mandatory audit firm rotation, imposing a short-term rotation will lead to lower audit fees and higher detection risk, resulting from greater informational frictions. We further find that imposing supplementary regulatory instruments, such as increased regulatory scrutiny of the auditee and/or auditor, can be used to lower the detection risk and increase audit quality. We discuss implications of these findings for empirical research.     

THE DETERMINANTS OF AUDIT FEES: SOME EMPIRICAL MODELS

This paper proposes a model of audit fee determination based upon size and other characteristics of the auditee and the auditor, and upon whether there has been a recent change of auditor (which might lead to a low-balling effect). A novel feature of the model is that auditee size is measured in two dimensions, sales and assets, and is allowed to have a quadratic relationship with audit fee. The model was estimated for a sample of large listed UK companies for the years 1981 to 1988. The results support the low-balling hypothesis and also provide insights into the distinctive role of the Big 8 firms in the audit market.     

Audit market structure,fees and choice in a period of structural change: Evidence from the UK – 1998–2003

This paper presents evidence on audit market concentration and auditor fee levels in the UK market in the crucial period of structural change following the PricewaterhouseCoopers’ (PwC) merger and encompassing Andersen’s demise (1998–2003). Given the current interest in auditor choice, analysis is also undertaken at the individual audit firm level and by industry sector. There is evidence of significant upward pressure on audit fees since 2001 but only for smaller auditees. Audit fee income for top tier auditors (Big 5/4) did not change significantly while the number of auditees fell significantly, consistent with a move towards larger, less risky, clients. A decomposition analysis of the aggregate Big 5/4 concentration ratio changes over the period identifies the impact of four distinct consumer-based reasons for change: leavers; net joiners; non-par auditor switches; and (only for the audit fees measure) audit fee changes. Andersen’s demise markedly reduced the level of inequality among the top tier firms but PwC retained its position as a ‘dominant firm’. On switching to the new auditor, former Andersen clients experienced an initial audit fee rise broadly in line with inflation, with no evidence of fee premia or discounting. They also reported significantly lower NAS fees, consistent with audit firms and auditees responding to public concerns about perceptions of auditor independence. There is no general evidence of knowledge spillover effects or cross-subsidisation of the audit fee by NAS. The combined findings provide no evidence to indicate that recent structural changes have resulted in anticompetitive pricing; the key concerns remain the lack of audit firm choice and issues concerning the governance and accountability of audit firms.     

Explaining Variability in External Audit Fees

This study examines the effect of several factors on the level of external audit fees using a multiple regression model. Audit fee data were provided by 95 US publicly held companies for the years 1983 to 1985. Variables measuring client industry membership and auditor involvement in the security registration process were proxies for client regulatory aspects. These variables were significant and provide support for the hypothesis that scale economies and/or specialization effects accrue to audit firms in dealing with the regulatory complexities faced by clients. Variables measuring auditee size and complexity, auditee/auditor loss sharing risk, and audit firm size were also significant in explaining variability in external audit fees.     

Deterring fraud by looking away

Individuals being audited potentially learn how to exploit the weaknesses inherent in any audit methodology if they face the same method many times. Hence, an auditor better deters fraud by randomizing her choice of methodology over time, thereby frustrating a would‐be fraudster's ability to learn. In the extreme, an auditor benefits from refusing to audit, even though audits are costless to her.     

Auditor Selection: What Influences Decisions by Listed Companies?

Major business failures, including Enron and World Com in the United States and Harris Scarfe and HIH in Australia, and related alleged audit failures, have put the choice of auditor on the agenda. The choice of the "right" auditor has economic consequences for an auditee and implications for corporate governance. This paper discusses factors important to explaining auditor choice, including institutional factors (pertaining to the auditee and auditor) and newer emerging criteria as well as networking between directors and auditors. The paper discusses the relevant research and the policy implications for good corporate governance of auditor choice in publicly listed companies.     

Evidence of Fraud,Audit Risk and Audit Liability Regimes

We investigate the effectiveness of proportionate liability in reducing the probability of fraud and audit risk relative to joint and several liability in two strategic audit settings: one that provides conclusive evidence of fraud and one that provides inconclusive evidence of fraud. In both settings the auditor makes an audit effort choice, but in the second setting the auditor also evaluates the audit evidence. Our results show that when the auditor chooses only effort, a proportionate liability rule with large marginal liability relief decreases audit risk. However, when the auditor also evaluates the audit evidence this result no longer holds.     

Determinants of audit fees in Bangladesh

This paper reports the results of an analysis of the determinants of audit fees of both financial and non-financial companies in Bangladesh. The Bangladeshi audit services market is unusual in that there is no direct involvement of international audit firms in it. The results of the regressions show that the size of the auditee has the greatest influence on audit fees. Whilst there was no international Big Six grouping, it was possible to construct a group of Bangladeshi audit firms which commanded a price premium, based on their size and whether they had a link with an international firm of auditors. Financial services companies were found to have higher audit fees relative to non-financial companies. Subsidiaries of multi-national holding companies also had higher audit fees. The surprising result was that auditees which employed at least one qualified accountant had higher audit fees.     

Negotiating the credibility of performance auditing

This paper reports the results of a longitudinal field study of a performance audit which used in-depth interviews and observation to examine the process by which auditees and auditors in the Australian National Audit Office (ANAO) negotiated their relationship. The findings enhance understanding of auditee reactions to both the practice of performance auditing and the auditors themselves and the impact that these have on the credibility of performance auditing. Using the lens of Oliver's typology of strategic responses, the study confirmed the prevalence of auditee responses to performance auditing by the ANAO which ranged from co-operative acquiescence and co-operation to confrontational defiance. The paper addresses recent and ongoing calls for more studies of public sector auditing in action to deepen our understanding of the responses or manoeuvring of auditors and auditees during the process of performance auditing. A key contribution of the paper is confirmation that performance auditing continues to be a contested activity and its credibility in practice remains uncertain. The empirical (and historical) evidence suggests that audits that are perceived as especially politically sensitive can provoke active forms of resistance, including avoidance and defiance.     

The case for process mining in auditing: Sources of value added and areas of application

Process mining aims to extract knowledge from the event logs maintained by a company's ERP system. The objective of this paper is to make the case for why internal and external auditors should leverage the capabilities process mining offers to rethink how auditing is carried out. We do so by identifying the sources of value added of process mining when applied to auditing, which are as follows: 1. process mining analyzes the entire population of data and not just a sample; 2. critically that data consists of meta-data—data entered independently of the actions of auditee—and not just data entered by the auditee; 3. process mining allows the auditor to have a more effective way of implementing the audit risk model by providing effective ways of conducting the required walkthroughs of processes and conducting analytic procedures; 4. process mining allows the auditor to conduct analyses not possible with existing audit tools, such as discovering the ways in which business processes are actually being carried out in practice, and to identify social relationships between individuals. It is our argument that these sources of value have not been fully understood in the process mining literature, which has focused on developing it as a statistical methodology rather than on applying it to audit practice. Only when auditors and audit researchers appreciate what is new and unique about process mining will its acceptance in auditing practice become feasible.     

审计失败中的审计责任认定与监管倾向:经验分析

监管者对审计责任的认定倾向是审计执业环境的重要构成。本文选取1999—2006年间中国证券市场发生的72例财务报表审计失败进行观测,发现:(1)在监管实践较早期间(1999—2002年间)的审计失败样本观测中,88.2%的审计师遭到处罚;而2003—2006年间的审计失败观测中仅有23.6%的审计师遭到处罚;(2)在控制了审计失败观测的公司受处罚严厉度、舞弊期跨度、舞弊期间审计意见类型以及审计师规模后,仍能检测到近年来审计责任认定的显著缓和趋势;(3)即使对于审计师受到处罚的审计失败观测,在1999—2002年间平均82.7%的虚假陈述事项需要由审计师承担审计责任,而在2003—2006年间仅有平均41.2%的虚假陈述事项须由审计师承担责任。综上,监管机构在近年来对会计师事务所或签字注册会计师的审计责任认定显著趋于缓和与稳健;审计执业环境的这种变化趋势亦可为未来监管和司法实践中的审计责任界定提供有益的借鉴。     

Auditor Market Share,Product Differentiation and Audit Fees

This study examines the effects of auditor market share and product differentiation on audit fees. Previous studies have attributed the price premium charged by the Big Eight (the Big Six in the present study) to Big Eight product differentiation. However, such a price premium could be partly due to monopoly pricing. In the present study, the Hong Kong audit market provides a unique setting in which a non-Big Six local auditor has a market share comparable to those of the third and fourth largest Big Six firms. This makes it feasible to control for the effects of market share via matching. Also, the wide disparity among the Big Six firms ‘market shares in Hong Kong makes it feasible to test for the effects of market power on audit fees. The results show that, consistent with prior studies, the Big Six audit firms charge higher audit fees than non-Big Six firms in the small auditee, but not the big auditee, market. This suggests that similar economic forces to those other audit markets are also at work in Hong Kong. Despite the Big Six firms’ widely different market shares, there was no price differentiation among them. Yet there was a Big Six price premium over the large local firm with a similar market share to those of two of the Big Six. Together, these results suggest that the Big Six price premium is a result of product differentiation rather than monopoly pricing.
