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.     

Audit Committee Effectiveness and Financial Reporting Quality: Implications for Auditor Independence

Auditors participating in a survey identified oversight of financial reporting and the external audit process, and ensuring quality internal controls, as the most important functions of effective audit committees. Financial literacy or expertise, independence, and a strong commitment to perform the job effectively were noted as important attributes. The results also suggest that although audit committees have enough power to confront management on contentious issues, they are not very effective in helping to resolve financial reporting disputes. Management was identified as a key influence in affecting the nature, extent, and quality of communication between the auditor and the audit committee. Most auditors believe that it is not important for each member of the audit committee to be an expert, but it is important that they are financially literate.     

Non‐Audit Service Fees and Financial Reporting Quality: A Meta‐Analysis

Auditing as a corporate governance mechanism has attracted considerable research attention. Because of the information asymmetry between corporate managers and outside shareholders, auditors are hired to provide independent assurance that financial statements are prepared following generally accepted accounting principles. The credibility of such assurance depends on the independence, both in fact and in appearance, of the auditor. Over the years, however, the independence of auditors has come under increased scrutiny because of their joint provision of both audit and non‐audit services. A sizable literature on the impact of non‐audit fees on financial reporting quality has developed. The evidence from this literature, however, remains inconclusive. This paper provides a meta‐analysis of the available literature by assessing (a) the net effect of non‐audit fees on financial reporting quality, and (b) whether there is homogeneity in the financial reporting quality proxies used in the extant literature. Findings suggest that the level of client‐specific non‐audit fees is associated with reduced financial reporting quality. However, the underlying studies used to conduct this meta‐analysis are not homogenous.     

Effects of Increasing Enforcement on Financial Reporting Quality and Audit Quality

A widely held assumption in policy making and empirical research is that increasing the strength of public enforcement improves financial reporting quality and audit quality. This paper provides a more nuanced view. In a model with a manager who can manage earnings, a strategic auditor, and an enforcement institution, we show that enforcement and auditing are complements in a weak enforcement regime but can be substitutes in a strong regime. Although stronger enforcement always mitigates earnings management, the effects of different instruments of strengthening enforcement are ambiguous. We show that they can improve or impair financial reporting quality and audit quality, depending on production risk, accounting system characteristics, and the scope of auditing relative to enforcement.     

Trust and Financial Reporting Quality

Using unique survey data from Great Place to Work® Institute, we investigate the association of intraorganizational trust (i.e., employees’ trust in management) with three aspects of financial reporting: accruals quality, misstatements, and internal control quality. We find that trust is associated with better accrual quality, lower likelihood of financial statement misstatements, and lower likelihood of internal control material weakness disclosures. However, these effects are not uniform across all companies. Consistent with trust improving financial reporting quality through improved information production and information sharing, we find that trust is significantly associated with financial reporting quality in relatively decentralized firms, but not in firms that are relatively centralized. Our results are robust to several analyses that attempt to control for potential alternative explanations.     

EC Green Paper Proposals and Audit Quality

In order to restore confidence in financial statements the European Commission proposes different measures to enhance audit quality. This paper examines potential effects of selected proposals on audit quality in the light of prior research findings. It concludes that an increased emphasis on substantive audit procedures may not be beneficial and that joint audits potentially improve competition and audit quality, but might increase audit fees. An appointment by a third party would strengthen auditor independence. The overall impact of a mandatory rotation of audit firms is unclear due to opposite effects on auditor competence and auditor independence. The provision of non-audit services might affect independence in appearance negatively. However, a total ban would not be necessary. Finally, a limit to the proportion of fees an audit firm can receive from a single client as well as a capping of non-audit fees seem to be desirable.     

Effect of international working experience of individual auditors on audit quality: Evidence from China

This paper investigates the effects of auditors with international working experience on audit quality in emerging markets. Such auditors are associated with better audit quality, a pattern that is further supported by an examination based on a propensity score matching sample that controls for endogeneity. Chief financial officers with international experience are more conservative in the client company of their auditors who have international working experience. Further, reviewer partners with international working experience provide better audit quality in terms of low accruals, less below‐the‐line items, and less audit reporting aggressiveness, while engagement partners with international working experience require high audit fees. Moreover, financial reports signed by auditors with international working experience significantly increase analyst forecast accuracy and decrease analyst forecast dispersion. Our results are robust to different specifications and alternative measures. Overall, this paper highlights the importance of human capital and provides direct evidence on how auditors with international working experience use their knowledge and audit skills in emerging markets.     

Determinants and implications of long audit reporting lags: evidence from China

Audit reporting lag is the single most important determinant influencing the timeliness of the release of financial statements. In this study, we first explore the determinants of audit reporting lags in China where the audit market for listed firms is dominated by non-Big 4 auditors. We then examine the implications of long audit reporting lags in subsequent years. We find that selected measures of audit risk and complexity, and auditor expertise are all associated with the length of audit reporting lags in China. Firms with long audit reporting lags are more likely to have the receipt of non-standard opinions in subsequent periods. There is also evidence that firms with extremely long audit reporting lags tend to have more restatements in the subsequent year. As prior research has not specifically investigated the consequences of long audit reporting lags in subsequent years, this study makes an important contribution to the literature in this area.     

Audit committee quality,auditor independence,and internal control weaknesses

In this paper we investigate the relation between audit committee quality, auditor independence, and the disclosure of internal control weaknesses after the enactment of the Sarbanes-Oxley Act. We begin with a sample of firms with internal control weaknesses and, based on industry, size, and performance, match these firms to a sample of control firms without internal control weaknesses. Our conditional logit analyses indicate that a relation exists between audit committee quality, auditor independence, and internal control weaknesses. Firms are more likely to be identified with an internal control weakness, if their audit committees have less financial expertise or, more specifically, have less accounting financial expertise and non-accounting financial expertise. They are also more likely to be identified with an internal control weakness, if their auditors are more independent. In addition, firms with recent auditor changes are more likely to have internal control weaknesses.
