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.     

External auditors’ reliance on internal audit: the impact of sourcing arrangements and consulting activities

This study examines the impact of internal audit outsourcing and involvement in consulting on external auditors’ reliance on the work of internal audit. We test whether these factors influence reliance on internal audit work already undertaken and the use of internal auditors as assistants, distinguishing between control evaluation and substantive testing. Involvement in consulting impacts reliance on work undertaken and the use of internal auditors as assistants for control evaluation. External auditors make greater use of internal auditors as assistants for substantive testing when internal audit is provided in‐house. Overall, external auditors use internal audit more for control evaluation tasks.     

Factors affecting the internal audit effectiveness: A survey of the Saudi public sector

This study assesses factors influencing internal audit effectiveness (IAE) in Saudi Arabia. Data were obtained from 203 managers and 239 internal auditors from 79 Saudi Arabian public sector organizations. Multiple regression analysis examines the association between IAE and five principal factors. Results suggest that management support for IAE drives perceived effectiveness of the internal audit function from both management's and the internal auditors’ perspective. Management support is linked to hiring trained and experienced staff, providing sufficient resources, enhancing the relationship with external auditors, and having an independent internal audit department. Saudi Arabia is representative of many developed and developing environments, and its recent tradition of governance and audit is mirrored in countries worldwide. Moreover, its specific cultural traditions involving clan and tribal allegiances, and pervasive and core religious beliefs, characterize the GCC countries, the Arab World generally, and indeed, many other developing countries, irrespective of wealth. Thus, links between management support and internal audit effectiveness are likely generalizable beyond the Saudi public sector context.     

The influence of litigation risk and internal audit source on reliance decisions

External auditor reliance on the work of internal auditors in an integrated audit of the financial statements and internal control is an important audit planning procedure that can impact audit efficiency and effectiveness. The purpose of this study is to examine how perceived auditor litigation risk and internal audit source affect external auditors' reliance decisions in an integrated audit environment under varying levels of risk of material misstatement. In an experimental study using 89 practicing Big 4 auditors, this study finds that auditors who perceive low litigation risk from placing reliance on the work of internal auditors will rely more on outsourced internal auditors than in-house internal auditors. The results also show that auditors' reliance decisions are sensitive to the level of account risk consistent with the risk-based approach to the integrated audit encouraged by the PCAOB.     

Audit committee quality indices,reporting quality and firm value

We investigate the relation between audit committee (AC) quality indices, financial reporting, internal control quality and firm value using a US dataset for the period 2002–12. The indices are developed by linking firm value with principal component analysis (PCA) factors based on a broad set of 82 AC variables, some of which influence the quality of the AC, but are not addressed in prior literature. Significant AC factors include ‘overlapping directors’, ‘busyness’ and ‘foreign director’, and we use these factors to develop ‘high’ and ‘low’ AC quality indices. We show that low AC quality firms are more likely to manage earnings, be external auditor dependent with respect to non‐audit tax services, and switch to a lower quality auditor. Low AC quality firms are also more likely to have internal control concerns disclosed by predecessor auditors, including accounting issues, financial restatements, audit opinion concerns and deficiencies that undermine internal control effectiveness. Further, they are more likely to receive an audit report containing additional explanatory notes. Conversely, high AC quality firms are significantly less likely to have these concerns. Our findings highlight the value of using AC quality indices in delivering greater oversight of the financial reporting process.     

The Effect of Litigation Risk Increase on Big N Auditor Exits and Audit Quality in the Korean Savings Banking Industry

This study investigates whether an increase in litigation risk results in Big N auditors leaving the industry and examines the impact of this increase on audit quality. Using a sample of Korean savings banks from 2009 to 2015, the study finds that the proportion of Big N auditors sharply decreases after a savings bank crisis, suggesting that Big N auditors are likely to reject riskier clients, while audit quality is unchanged. The results provide new evidence that an increase in litigation risk does not necessarily increase audit quality. The findings have academic and practical implications, as they suggest that policies for improving audit quality should consider auditors’ strategies in response to litigation risk.     

The impact of audit committee quality on financial reporting quality and audit fees

This study examines the association between the quality of audit committees on financial reporting quality and external audit fees in an environment where the formation of audit committees was unregulated. The study uses a sample of 87 New Zealand firms in 2001 when no regulations or listing rules existed for audit committees. The results show no significant association between the quality of an audit committee and the quality of financial reporting. These results are robust to alternative measures of earnings quality. Similarly, the quality of audit committees has little impact on the level of fees paid to external auditors. The results suggest that the benefits of ‘best practice’ audit committees may be less than anticipated by regulators and policymakers.     

Evaluating the Work of Internal Audit: A Comparison of Standards and Empirical Evidence

Numerous changes have recently been proposed or made to audit standards providing guidance for external auditors' evaluations of internal audit work. This paper reports the results of a study to compare the UK's Accounting Practices Board Statement of Auditing Standard 500, first, with similar standards promulgated by international, Canadian and US societies, and second, with audit quality factors derived from practising internal auditors. The data for the latter comparison was obtained from a two-phase study that first generated a set of potential quality factors through intensive structured interviews with audit groups from six different and diverse organisations, and then obtained evaluations of these factors from a large sample of internal auditors worldwide. Results first indicate that there are strong similarities between the guidance provided by SAS 500 and that proposed or promulgated by the UK, international, Canadian and US audit groups. Furthermore, the guidance provided by these SASs for items to consider in evaluating the quality of internal audit work are largely in agreement with the factors determined by practising internal auditors. There are, however, several items listed in SAS 500 that are not considered useful by internal auditors and there are other factors considered crucial by internal auditors but not mentioned in the SASs.     

Internal Audit Outsourcing: A Literature Synthesis and Future Directions

The internal audit function (IAF), which has traditionally been an in‐house function, is increasingly being outsourced to outside consultants, in line with global trends for other services. This study synthesises research on the outsourcing and co‐sourcing of internal audit services over the last three decades, and suggests directions for future research. It draws from professional and academic literature to highlight the nature of organisations that outsource the IAF, and the main reasons behind the outsourcing decision. The study further examines the financial impact of outsourcing, as well as its impact on financial reporting, internal audit quality and auditors’ independence. The study shows widespread adoption of outsourcing of internal auditing services, largely due to the perceived cost benefits as well as perceived improved access to specialised internal auditing resources. There are mixed findings on the impact of outsourcing of internal auditing services on quality, cost, independence and availability of resources. This study contributes to internal and external audit, corporate governance and outsourcing literature in general, by synthesising the existing research and providing a roadmap with which to understand the origins, development, present state and impact of outsourcing of internal auditing.     

Organizational legitimacy,conflict, and hypocrisy: An alternative view of the role of internal auditing

This article provides a commentary on Everett and Tremblay's (2014) analysis of ethics and internal audit by further exploring the role of the internal audit function within Nils Brunsson's model of organized hypocrisy (Brunsson, 1986, Brunsson, 1993, Brunsson, 2002). Specifically, we extend Everett and Tremblay's discussion of internal auditors as ‘moral’ actors and propose that the counter-coupling of an organization's primary outputs–talk, decision and action–provides internal auditors with the necessary tools to carry out conflicting ethical roles within the organization.     

Internal audit reporting lines,fraud risk decomposition,and assessments of fraud risk

The main purpose of this research is to examine the effects of internal audit reporting lines on fraud risk assessments made by internal auditors when the level of fraud risk varies. Significant emphasis has been placed on the importance of reporting lines in maintaining the autonomy of internal auditors, but the perceived benefits of requiring internal audit to report directly to the audit committee have not been validated or systematically investigated. Results of an experiment involving 172 experienced internal auditors and additional survey findings indicate that internal auditors perceive more personal threats when they report high levels of risk directly to the audit committee, relative to management. Perceived threats lead internal auditors to reduce assessed levels of fraud risk when reporting to the audit committee relative to when reporting to management. This finding runs counter to the anticipated benefits of requirements that the internal audit function report directly to the audit committee, and it reveals potential conflicts of interest and independence threats created by the audit committee itself. We also investigate the effects of fraud risk decomposition on risk assessments made by internal auditors. We find that fraud risk assessment decomposition does not have the same effects on internal auditors as it has on external auditors, and the effects of decomposition do not align with the expected benefits of decomposition.     

The Small Company Audit Qualification: A Preliminary Investigation

In recent years there has been much debate in the UK regarding the value and feasibility of the small company audit. The lack of formal internal control systems and the application of universal auditing standards has given rise to the use of a special ‘Small Company (Example 6) Audit Qualification’. However, doubts concerning the uniformity of practice between auditors has created difficulties for users in interpreting its meaning. This paper examines the extent to which a number of financial, organisational and auditor variables are able to explain the receipt of a ‘Small Company Audit Qualification’. The main empirical findings, using multivariate logistic analysis on a sample of 540 small company reports, are that companies audited by large audit practices, companies which had a prior year qualification, a secured loan, declining earnings, large audit lags and few non-director shareholders were more likely to receive an audit qualification than other companies.     

The Effect of Auditor Style on Reporting Quality: Evidence from Germany

This paper examines whether the ‘style’ of individual auditors influences financial reporting quality in Germany. Audit quality in Germany should be uniformly high, because of strong reputational needs, strict controls on operating procedures, and quality enforcement mechanisms. An audit partner's style should not affect this quality level. However, our results do not support this expectation. Exploiting a unique dataset comprising the names of the audit engagement and review partners of listed German companies, we find that audit engagement partners in Germany have a significant influence on audit quality, beyond firm‐ and office‐level factors. In contrast, audit review partners do not have a consistent significant influence on audit quality. We measure audit quality by the level of a firm's abnormal accruals and its propensity to meet or beat an earnings target. We also find that the 2005 adoption of a new audit quality enforcement system that includes ‘naming and shaming’ does not reduce the influence of audit partner style on financial reporting quality.     

Some Implications of Auditor and Client Lobbying Activities: A Comparative Analysis

This paper examines the degree to which auditor and client lobbying is related in a UK context. This may help to identify any linkage between the wealth of clients and auditors that is affected by accounting standards, as propounded in the ‘economic consequences’ literature. It also might have some implications for the independence question. Three tests are conducted to see if auditors tend to support the lobbying position of the majority, or the most financially influential, of their clients. The third test is also used to identify any evidence that the comments of smaller clients tend to follow the lead of their audit firms/professional advisors. Auditor and corporate client written submissions on 22 proposed accounting standards are included in the study. The analyses are conducted both at an aggregated and also at a disaggregated level. The results do not indicate that auditor and client collusion took place. In particular, the results are consistent with the view that auditors are independent of their clients. Some suggestions are made for further research.     

New development: Breaking out or hanging on? Internal audit in government

Public audit is in transition. On the one hand, professional organizations claim it is time ‘to break out’ and develop new roles for auditors that ‘add more value’. On the other hand, critics are concerned about public sector accountability deficits necessitating more control and urging auditors to hold on to their traditional role. This article discusses tensions and relevance between these positions and their implications for auditing in government. The article will help policy-makers in their strategic decision-making on the role and focus of internal audit in government.     

AUDITOR PREFERENCES FOR LIABILITY LIMITATION

Debate over statutorily limiting auditor civil liability has implicitly assumed auditors are homogeneous in their preferences for capping liability. This study examines the preferences of auditors for limiting auditor liability and investigates reasons for the preferences. The study uses an Australian setting in which there has been a persistent debate for a decade or more over regulatory intervention in this area. The study provides a background to the debate over this issue and addresses the effects of two factors suggested by the extant literature, namely auditor size and the business risk of an auditor's client portfolio. These factors are argued to affect the expected costs of litigation facing auditors and therefore their preferences on capping liability. Using the submissions by audit firms on an Australian Companies and Securities Law Review Committee Discussion Paper on limiting auditor liability, the study finds larger audit firms that have greater capacities to lobby and greater expected costs of litigation from unlimited liability than smaller firms, dominate the respondents on the Paper and tend to be more supportive of liability limitation than smaller audit firms. Within the array of possible methods of capping liability canvassed by the Discussion Paper, the study documents evidence of diversity in preferences among audit firms. Larger audit firm size is associated with a preference for a group of methods that provides such firms with opportunities to benefit from the capping at the expense of the smaller audit firms. The method most preferred by the larger audit firms is the multiple of fee with a prescribed minimum. Perhaps not surprisingly, this is also the preferred method of the professional accounting bodies in Australia. As to the effect of the riskiness of the client portfolio on preferences for methods of limiting liability, the study finds that higher business risk in an auditor's portfolio is associated with a preference for methods that give greater control over their liability exposure. The study has implications for the impact of regulation of capping liability on competition in the audit services market.     

The Contribution of Internal Audit as a Determinant of External Audit Fees and Factors Influencing This Contribution

Despite extensive research on the determinants of external audit fees, there is little empirical evidence on the effect of internal audit contribution on the external audit fee. Using a cross-sectional regression model based on prior audit fee research, this study provides evidence that internal audit contribution is a significant determinant of the external audit fee. Further, a second model that provides evidence on the determinants of internal audit contribution is developed and tested. This second model indicates that internal audit contribution is influenced by internal audit quality and, conditional on the level of inherent risk, the availability of internal audit and the extent of coordination between internal and external auditors. These results are based on a unique data-set comprised of publicly available data matched with survey responses from internal and external auditors affiliated with 70 non-financial services Fortune 1000 firms. The sample includes all of the former "Big 6" international accounting firms and clients from twenty-nine different industries.

A study of whistleblowing among trainee auditors

Over the last number of years whistleblowers have been gaining prominence. This paper investigates some of the factors that influence the propensity or willingness to blow the whistle among trainee auditors. Three categories of factors are examined: audit firm organisational structures, personal characteristics of whistleblowers and situational variables.A survey of 240 final year students of the Institute of Chartered Accountants in Ireland was undertaken. Trainee auditors (just about to sit their finals) were asked about their confidence in internal and external reporting structures in their firms. Using four scenarios, audit trainees were questioned on their willingness to challenge an audit partner's inappropriate response to concerns raised during the audit. Finally, audit trainees were asked about the influence of legal protection on their likelihood of whistleblowing.Results indicate that where firms have adequate formal structures for reporting wrongdoing, trainee auditors are more likely to report wrongdoing and have greater confidence that this will not adversely affect their careers. Training increases this confidence. Trainee auditors also express a willingness to challenge an audit partner's unsatisfactory response to wrongdoing. Significant differences were found in attitudes depending on whether the reports of wrongdoing were internal or external. The willingness to report wrongdoing externally reduces for older (aged over 25) trainees.
