An evidential reasoning approach to Sarbanes-Oxley mandated internal control risk assessment

In response to the enactment of the Sarbanes-Oxley Act 2002 and of the release of the Public Company Accounting Oversight Board (PCAOB) Auditing Standard No. 5, this study develops a risk-based evidential reasoning approach for assessing the effectiveness of internal controls over financial reporting (ICoFR). This approach provides a structured methodology for assessing the effectiveness of ICoFR by considering relevant factors and their interrelationships. The Dempster-Shafer theory of belief functions is utilized for representing risk.First, we develop a generic ICoFR assessment model based upon a Big 4 audit firm's approach and apply it to a real-world example. Then, based on this model, we develop a quantitative representation of various levels of ICoFR effectiveness and related risk-assessment as defined by the PCAOB and contrast these representations with levels implied by Auditing Standard No. 5. In doing so, we demonstrate the potential value of formal risk assessment models in both facilitating the assessment of risks in an individual engagement and in assessing the effects of different regulations.

Communication of risk assessment information to risk managers

This article describes the results of a two-phase study of risk communication between risk assessors and risk managers (including policy makers). The first phase consisted of telephone interviews with 30 air quality risk managers from all levels (18 from local, state, and regional offices, and 12 from national offices). The second phase involved a focus group with 11 senior EPA risk managers representing a broad range of EPA national offices and programmes. The two-hour focus group elicited responses from the risk managers to specific examples of videotaped risk information created by agency risk assessors. The risk managers indicated their interests in hearing both qualitative and quantitative information about risk and emphasized the importance of discussing other information about the decision context. Similar responses to the videotaped risk information were elicited from a class of students at the Harvard School of Public Health. This exploratory work suggests that to better inform risk managers, risk assessors must also appreciate and present the broader context of the decision, and they must convey how uncertainties and weaknesses in the assessment may influence stakeholder perceptions of risk and the effectiveness of different risk management options. Further research on how to communicate risk information to risk managers is recommended.     

An examination of order effects in auditors' inherent risk assessments

While recency effects have been reported in a variety of audit tasks, recent studies suggest that these effects may be mitigated under certain conditions. The importance of investigating order effects in auditors' judgments rests with its potential to impact on the efficiency and effectiveness of audits. Since current studies suggest that recency effects may not impact on all audit situations, it is necessary to identify conditions or variables in the task environment that either induce or mitigate recency.
This study examines the occurrence of order effects in auditors' inherent risk assessments, a task not previously examined. Using a case study administered to 70 auditors, this study found that auditors' judgments were not influenced by the order in which audit evidence was evaluated. Rather, the results suggest that judgments of inherent risk may be biased towards conservatism. This may not be surprising given the negative consequences associated with failing to adequately plan an audit. This may cause auditors to act cautiously and thus mitigate recency effects.     

Assessing inherent risk during audit planning: The development of a knowledge based model

Within the academic and professional auditing communities there has been growing concern with accurately assessing the various risks associated with the performance of an audit. One approach to developing sophisticated risk assessment models is to study how experienced expert auditors use industry and firm specific factors in making audit judgements. This study presents a model of inherent risk assessment based on literature reviews and a field study that involved structured and unstructured interviews and observations of experts in audit planning meetings. Analysis of the data gathered led to the specification of a conceptual model of inherent risk assessment which has been implemented as a computer program (a computational model). Auditors were asked to assess the behavior and performance of the computational model as a first step in evaluating the expert model.     

The portfolio of knowledge required by industry specialist auditors

While a number of studies have shown the superior performance of industry specialist auditors, prior research has not examined the underlying knowledge categories reflective of a specialist. This study aims to identify the range of knowledge required to be a successful industry specialist auditor, and the ways in which this knowledge is and might best be acquired. A multi-method approach was employed, including the use of a free-list task to identify important categories of knowledge, and a structured questionnaire. The questionnaire examined several issues including current knowledge of specific items, extent to which specialist knowledge is reflected in the firm's support systems, and methods by which this knowledge was, and could be, acquired. Participants, designated insurance industry specialists from a Big 4 firm, identified a large range of knowledge items, and there was a large degree of consensus between the results arising from the two knowledge identification research methods utilised. The results also revealed a number of perceived deficiencies in the level of current knowledge and the extent to which specialised knowledge is reflected in support systems. Few differences were found in the knowledge requirements of the two industry sub-specialisations, life insurance, and property and casualty insurance. Except for industry and economic factors, on-the-job experience was found to be the most prevalent method of gaining industry specialist knowledge. However, there was support for greater formal training and improved firm support systems for several specific knowledge items.     

The use of analytical procedures by external auditors in Canada

The Enron debacle and other scandals highlight the issue of whether analytical procedures (APs) or more traditional audit approaches based on substantive testing are more appropriate. This paper surveys the use of APs by Canadian external auditors and augments understanding of the impact of auditing standards on professional practice. Our results demonstrate that APs are extensively applied in practice, particularly by larger firms, and that their use dominates the final review stage of the audit regardless of firm size. While standards do not appear to be an important influence upon practice for audit firms in general, this is not the case for smaller firms. Though auditors place more reliance on APs to reduce tests of detail, there are limits to this reliance. Our results indicate that while auditors may have increased their use of APs with the expectation of efficiency gains, these may be realized at present only partially.     

The effects of tone at the top and coordination with external auditors on internal auditors’ fraud risk assessments

Prior research suggests that internal auditors’ judgements are subject to management influence resulting in compromised risk assessments. This study investigates the effects of the tone at the top and coordination with external auditors on internal auditors’ fraud risk assessments. Results of an experiment involving 64 internal auditors indicate that when the tone at the top is poor, rather than favouring management, internal auditors report a higher risk of intentional misstatements and that coordination with external auditors can further reduce expectations of the incidence of intentional misstatements.     

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.     

SEC communications to the independent auditors: An analysis of enforcement actions

All 415 SEC releases issued between the end of 1972 and the end of 1989 were analyzed to clarify the SEC's philosophy of independent auditing and to document the violations of generally accepted auditing standards (GAAS) reported in the releases. Among the findings are 1) the SEC consistently concluded that the primary purpose of an independent audit is to enhance the efficiency of the capital markets and help protect the investing public by providing reasonable assurance concerning the integrity of the financial statements and related disclosures; 2) the SEC attributed many independent audit failures to questionable independent auditor judgement in adhering to professional standards, most often because of insufficient gathering of audit evidence due to over-reliance on management representations; 3) the large majority of cases in which the SEC associated the auditor with fraudulent financial reporting (usually constructive fraud) involved smaller audit firms; 4) the large majority of cases of management fraud in which the auditors were deceived by clients involved large audit firms. In the final section of this paper, we discuss the influence of enforcement releases on independent audit standard setting and possible implications for the audit profession in the future.     

Disclosure of fees paid to auditors and the market valuation of earnings surprises

We investigate if the SEC’s recently mandated disclosure of fees for audit and nonaudit services paid by firms to their incumbent auditors affected the market’s perception of auditor independence and earnings quality. Following the initial fee disclosures in 2001, we find that the market valuation of quarterly earnings surprises (earnings response coefficient) was significantly lower for firms with high levels of nonaudit fees than for firms with low levels of such fees. In contrast, in the year prior to the new fee disclosures, there was no reduction in earnings response coefficients for firms that subsequently reported high nonaudit fees. Our evidence suggests that mandated fee disclosures provided new information that was viewed by the market as relevant to appraising auditor independence and earnings quality.

The impact on the market for audit services of aggressive competition by auditors

Supporters of direct uninvited solicitation activities argue that clients can make more informed choices of auditors when auditors are allowed to solicit prospective clients. In banned markets, auditors are allowed to submit bids to provide audit services only when invited by the client. This study provides theoretical models that examine the efficiency of client–auditor alignments in the banned and allowed market. We identify conditions under which realignment differences between the two markets occur and derive client losses in the banned market as compared to the allowed market. We also identify conditions under which independence may be impaired in the allowed market, consistent with the claims of solicitation opponents. However, we believe that, in view of the potential positive effects related to audit pricing and client–auditor alignment, restrictions on advertising or direct uninvited solicitation are not necessarily indicated. Instead, regulators or market mechanisms should insure that the independence (truth-telling) condition is so readily satisfied as to be virtually irrelevant. This can happen in one of two ways: (a) increased scrutiny, leading to an increased likelihood of discovery, or (b) increased penalties when an audit failure is discovered, leading to increased costs of an audit failure, or both.     

External auditors' willingness to rely on the work of internal auditors: The influence of work style and barriers to cooperation

The extent to which external auditors rely on the work of internal auditors is an important judgment. Recently, the Public Company Accounting Oversight Board has recommended that external auditors “rely (more) on the work of others” to reduce the greater-than-expected costs associated with compliance with Section 404 of the Sarbanes–Oxley Act. Reliance decisions, however, are complex decision tasks that require professional judgment and may be influenced by a number of factors, both external (environmental) and internal (cognitive and affective), including the auditors' working style and pervious experiences related to barriers to external/internal auditor cooperation (e.g., previously experienced low versus high internal auditor objectivity and/or competence). We experimentally examine these influences in our research reported herein. Consistent with expectations, external auditors' work styles significantly influenced the extent of planned audit testing, internal auditor reliance judgments, and interpretation of analytical procedures results. Auditors' perceptions about internal auditors' competence and objectivity, developed over years of interaction, also influenced these judgments, and interacted with work styles. Inconsistent with expectations, auditor rank (senior versus manager) did not influence judgments.

The effects of experience and task difficulty on accuracy and confidence assessments of auditors

This study extends prior research in psychology and auditing by examining the effects of audit experience and task difficulty on control risk evaluation. It also examines whether the effect of framing is mitigated by the simultaneous presentation of information. Ninety‐eight auditors performed a control risk evaluation task and recorded their judgement and their confidence. We find that judgement confidence increases with audit experience and that judgement confidence decreases as perceived task difficulty increases. However, we find no relation between audit experience and judgement accuracy or between perceived task difficulty and judgement accuracy. In addition, we find a significant negative relation between judgement confidence and judgement accuracy, which indicates that the participants' confidence is not appropriate. As expected, there is no framing effect when information is presented simultaneously.     

An empirical assessment of reinsurance risk

We analyse the effect of failing reinsurance cover on the stability of Dutch insurers. As insurers often reinsure themselves with other (re)insurers, a firm's loss could spread contagiously through the sector. Using a unique and confidential data set on reinsurance exposures, we gain insight into the reinsurance market structure and perform a scenario analysis to measure contagion risks. Considering entities on a standalone basis, we find no evidence of systemic risk in the Netherlands, even if multiple reinsurance companies fail simultaneously. At group level our analysis points to the contagion risk of in-house reinsurance structures, given that such in-house reinsurance parties are generally not higher capitalised than other group members.
