Relation between external audit fees, audit committee characteristics and internal audit

This study examines whether the existence of an audit committee, audit committee characteristics and the use of internal audit are associated with higher external audit fees. Higher audit fees imply increased audit testing and higher audit quality. We find that the existence of an audit committee, more frequent committee meetings and increased use of internal audit are related to higher audit fees. The expertise of audit committee members is associated with higher audit fees when meeting frequency and independence are low. These findings are consistent with an increased demand for higher quality auditing by audit committees, and by firms that make greater use of internal audit.     

An Investigation of Audit Committees' Oversight Responsibilities

Audit committee performance has come under close scrutiny in recent years from a variety of policy-makers, interest groups and researchers. In particular, the adequacy of audit committee oversight has been challenged. At the same time, audit committees are under pressure to increase the scope of their oversight work. This study examines audit committee oversight from the internal perspective of active U.S. audit committee members. A two-part survey used Wolnizer's (1995) list of seventeen prescribed audit committee objectives related to accounting and reporting, auditors and auditing, and corporate governance in general as a basis to assess audit committee members' abilities to recognize their assigned objectives and explore their perceptions of the key tasks and issues currently addressed by audit committees. The results indicate that audit committee members appreciate the importance of all audit committee members having sufficient expertise in oversight areas related to accounting, auditing and the law. However, some respondents agreed they lacked sufficient expertise in many or all of these areas. In addition, the findings indicate that audit committee members tend not to recognize their assigned responsibilities, but agree with the proposed expansion of committee responsibilities. Using a multimethod approach, internal control evaluation was consistently listed and ranked as the most important oversight responsibility. These findings provide insight into the priority perceived by audit committee members as to their oversight responsibilities, and the adequacy of U.S. reporting disclosures as signals of audit committee work.     

审计委员会:本原性质与作用机理

本文研究审计委员会的本原性质和其在公司治理中的作用机理,并剖析以美国为代表的现行审计委员会制度安排。本文分析指出,审计委员会的本原性质在于,它是代表股东利益直接负责企业外部会计事务,并享有企业内部会计事务的消极权力,从而确保注册会计师对经理人的独立性,以降低企业治理成本。审计委员会的作用机理则需基础于其本原性质而设计。而以美国为代表的现行制度安排下的审计委员会不是符合本原性质的审计委员会,其性质是经理人为履行自身向股东等诚实报告之受托责任而专设的职能管理机构。     

Some Economics of Audit Market Reform

The purpose of audit market reforms since 2001 is to restore public confidence in the institution of auditing based on two considerations: (1) ensuring audit quality; and (2) controlling the ‘adverse effect of competition’ in audit supply. Market reforms for audit quality are delivered through a package of prescribed actions motivated by an analytical relationship between audit quality and its possible determinants: (1) limiting audit tenure through a combination of mandatory firm rotation, partner rotation and re‐tendering; (2) limiting provision of non‐audit services (NAS) by the incumbent auditor; and (3) joint auditing and empowering the audit committee to enhance audit quality. This paper examines the competing independence hypothesis and expertise hypothesis that produce ambiguous theoretical relationships for audit quality–audit tenure and the independence‐provision of NAS. We then review whether the empirical literature resolves these conundrums. We also review the usefulness of joint auditing and empowering the audit committee to improve audit quality in the context of audit market reform.     

Internal audit: A comfort provider to the audit committee

This study, based upon four Belgian case studies, provides insights on (1) what drives the audit committee to look for the support of the internal audit function; and (2) what makes the internal audit function an expert at providing comfort to the audit committee [Pentland, B.T., 1993. Getting comfortable with the numbers: auditing and the micro-production of macro-order. Accounting, Organizations and Society 18 (7–8), 605–620; Carrington, T., Catasús, B., 2007. Auditing stories about discomfort: becoming comfortable with comfort theory. European Accounting Review 16 (1), 35–58]. We found that audit committees seek comfort, with respect to the control environment and internal controls, two areas in which they confront considerable discomfort. Besides the internal audit function's traditional assurance role, its involvement in improving internal controls provides a significant level of comfort to the audit committee. Internal auditors' unique knowledge about risk management and internal control, combined with appropriate inter-personal and behavioural skills, enables them to provide this comfort. Besides, their internal position, their familiarity with the company, and their position close to people across the company facilitate internal auditors being a major source of comfort for the audit committee. Formal audit reports and presentations, together with informal contacts, seem to be important symbols of comfort [Power, M., 1997. The Audit Society: Rituals of Verification. Oxford University Press, Oxford]. In addition, we found that the overall level of comfort to the audit committee can be enhanced via collaboration between internal and external auditing (the so-called ‘joint audit approach’).     

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.     

审计委员会制度与中国上市公司治理创新

本文研究中国上市公司现行治理结构中的企业会计事务控制权安排及其缺陷,并提出改进措施。我们研究发现,在中国上市公司现行治理结构中,企业经理人不仅拥有企业内部会计事务的积极权力,而且实质拥有企业外部会计事务的积极权力,其中的作为董事会下设专门委员会的审计委员会不是我们所设计的本原性质的审计委员会,而是接近于美国现行公司治理结构中的审计委员会。这一安排不符合关于现代企业会计事务控制权安排的分权制衡原则,难以保证注册会计师审计的独立性。我们在分析中国上市公司治理中的监事会监督为什么会流于形式的基础上,提出应进行中国上市公司治理的创新,即取消监事会(制度),设立独立于董事会与之平行的符合本原性质的审计委员会,或将监事会改造为符合我们界定的本原性质的审计委员会。     

Audit firm, corporate governance, and audit quality: Evidence from Bahrain

The aim of this research is to document the perceptions of credit and financial analysts with regard to the relationship between the effectiveness of audit committee, size of the auditing firm and audit quality in the context of Bahrain, which is characterized by a developed financial sector, low-liquidity stock market, low turnover in board of directors of listed firms, an inactive merger and acquisitions market and almost non-extent litigation. A survey of 300 credit and financial analysts shows that analysts considered auditors' opinion useful. Both credit and financial analysts see the credibility of financial statements to be a function of the size of the auditing firm. Both groups assume that the characteristics of Big-Four firms allow them to produce better-quality reports than non-Big firms. Non-audit services were found to affect auditor's independence and hence impair audit quality. Both the groups of analysts believe that effective audit committee enhances the quality of audit reports. Financial analysts perceive financial statements to be more credible than do credit analysts.     

Audit committee diligence around initial audit engagement

Studies focusing on governance mechanisms argue that auditor monitoring is one of several governance mechanisms that exist in the firm, and these mechanisms supplement each other. Extending this argument, I examine whether firms support auditor monitoring with audit committee monitoring when auditor oversight is deemed to be weak. Prior auditing literature argues that audit quality is affected by auditors' lack of familiarity with their clients' activities. Since lack of auditor–client familiarity exists in the first year of auditor–client tenure, I examine whether firms increase their audit committee monitoring during the year of auditor change. For a sample of firms that changed auditors between 2006 and 2012, the findings show that audit committees meet more frequently in the first year of audit engagement. Further tests show that firms' past reporting behavior play a significant role in the demand for more audit committee meetings and the increase in the audit committee meetings in the initial year of auditor engagement positively affects reporting quality.     

Audit Committee Members: What Goes on Behind Closed Doors?

Using a qualitative research paradigm, this study examines audit committee effectiveness from the perspective of audit committee members of New Zealand listed companies. The findings reveal that audit committee members perform a range of overlapping tasks and justify their existence in their audit committees by fulfilling the ‘expectations’ that are placed on them. Many quantitative research studies have examined the association between different dimensions of audit committee inputs and financial reporting outputs. The empirical evidence, however, is mixed and remains far from conclusive (Bédard and Gendron 2010). One of the primary reasons for the inconsistent findings is the lack of understanding of the actual process by which audit committees perform their responsibilities. Using a qualitative research paradigm, this study examines audit committee activities, processes and effectiveness from the perspective of audit committee members of New Zealand listed companies. The study argues that performing audit committee duties is an intended process, whereby audit committee members justify their actions and the effectiveness of their audit committees. The paper contributes to the limited literature on how audit committees operate and, by doing so, provides possible explanations for the inconsistent findings of the quantitative audit committee research. In particular, the paper invites further discussion on whether audit committee members can be (or should be assumed to be) independent when discharging their role of overseeing auditing and financial reporting‐related matters.     

Are fully independent audit committees really necessary?

Accounting scandals and concerns about the quality of financial statements have led to many calls for improved audit committee effectiveness. Prior research indicates that audit committee independence is positively related to effective oversight of the financial reporting process. Unfortunately, prior research has not provided an answer as to how much independence on the audit committee is enough. This is an important unanswered question because while Section 301 of the Sarbanes-Oxley Act of 2002 (SOX) currently requires all listed companies to maintain an audit committee that is 100% independent there has been much debate regarding easing the SOX requirements for smaller and foreign companies. In this paper we examine whether the regulatory requirements of a completely independent audit committee are necessary to obtain the monitoring benefits related to audit committee independence that have been documented in prior literature. Our results suggest that the benefits of audit committee independence are consistently achieved only when the audit committee is completely independent. These results provide support for the SOX requirement of 100% independent audit committees.     

Do investment in and the sourcing arrangement of the internal audit function affect audit delay?

This paper investigates the association between the internal audit function attributes and audit delay using a sample of 432 publicly traded firms in Malaysia in 2009. In this unique setting, we capitalize on the publicly available data concerning the investment in and the sourcing arrangement of internal audit function. We find a negative relationship between the costs incurred for the internal audit function and audit delay. However, we do not find any significant association between the internal audit function sourcing arrangements and audit delay. Additionally, we find that greater audit committee independence and longer auditor–client tenure shorten audit delay, and more frequent audit committee meetings and higher misstatements in the preliminary unaudited earnings are associated with a longer audit delay.     

The influence of corporate governance mechanisms on the quality of financial reporting and auditing: Perceptions of auditors and directors in Singapore

This study uses two hypothetical cases to examine the perceptions of auditors and directors in Singapore about corporate governance practices relating to the quality of financial reporting and auditing. In the first case, the strength of the audit committee, the existence of an internal audit function and the strength of a corporate code of conduct were manipulated. All three variables were perceived to have some influence on financial reporting and audit quality. However, some interesting differences were found between the perceptions of auditors and directors. Auditors place more weight on the internal audit function, possibly due to their familiarity with the role that internal audit can play in reducing audit risk and enhancing controls. Directors have more confidence in board enforcement of a strong code of conduct, possibly reflecting the view that this encourages staff to adhere to higher ethical standards. In the second case, audit partner rotation, outsourcing of internal audit services and whether the audit firm audited all companies within a group were manipulated. Auditors believed that their ability to resist management pressure was enhanced when they audited all companies within the group. No significant differences were found for the other variables, suggesting that neither group believes that these practices impair audit independence.     

独立性威胁、审计委员会制约有效性:理论分析与实证研究

本文在理论上深入分析审计制度安排中独立性威胁现象及审计委员会制度对独立性威胁的制约作用之后,基于2002—2004年我国上市公司审计委员会设立的基本情况,以审计意见和事务所变更为反应变量,对审计委员会制约独立性威胁的有效性进行了实证研究。研究发现,设立审计委员会的公司更不易被出具非标准审计意见,说明审计委员会的设立并不能有效提高审计师的独立性,但这同时也是反映政策效应的结果,即规模较大的上市公司倾向于主动配合监管政策设立审计委员会。本文的研究还发现,审计委员会的设立并不能令审计师免于因出具令上市公司不满的审计意见而被改聘的结果,说明我国的审计委员会制度未能在制约独立性威胁方面发挥作用,该结论同时得到实践调查结果与补充检验的支持。据此,本文认为,我国审计委员会制度在制约独立性威胁方面的功能还有待于进一步落实。     

State audit budgets and market assessments of credit risk

While financial statement auditing dominates the market for corporate auditing, internal controls and operational auditing appear to be emphasized in governmental markets. The size of the governmental audit budget (beyond the minimum level prescribed by generally accepted auditing standards) is ultimately a cost/benefit decision, with lower borrowing costs being one of several potential benefits. In testing for empirical regularities between auditing quantity and investor decisions, we found the size of the audit budget to be indeed associated with borrowing costs, but the direction of the relationship was anomalous. The anomalous positive sign for the audit budget variable could be due to self-selection bias. Self-selection bias is a confounding effect that has come up repeatedly to muddy the interpretation of empirical findings in prior (corporate) market based research on discretionary accounting variables. The supply of (discretionary) internal and operational audits may be driven by operational considerations (e.g., internal control weaknesses), which cannot be directly observed by outsiders. The bond markets may be interpreting the size of the audit budget as a signal about underlying economic characteristics that make the state a more risky investment. Alternatively, larger state audit budgets may signal less use of private sector auditors and be interpreted as less useful to investors (though, possibly more useful to governmental concerns focusing on compliance issues). Despite the inclusion of CPAs' audit fees in state budgets, the signal “inferred” for the state's municipalities may have a carryover effect onto state issues.     

Audit committee composition and the use of an industry specialist audit firm

Independent, competent boards of directors and audit committees are said to be important mechanisms of corporate governance. The purpose of the present study is to empirically examine the association between audit committee composition and audit quality. Specifically, the link between the proportion of non‐executive directors on an audit committee, financial qualifications of directors and the number of audit committee meetings held in a year are investigated and expected to have a positive association with the quality of the audit firm used. Audit quality is proxied by industry specialization. The results support the link between a higher proportion of non‐executive directors on an audit committee and use of an industry specialist audit firm. Other measures of audit committee quality (those with a higher proportion of directors with financial qualifications and those that meet more frequently) are not significantly associated with the use of an industry specialist audit firm. Sensitivity analysis shows that the presence of an audit committee is linked to use of an industry specialist audit firm.     

Audit committees and earnings quality

This research investigates whether audit committees are associated with improved earnings quality for a sample of Australian listed companies prior to the introduction of mandatory audit committee requirements in 2003. Two measures of earnings quality are used based on models first developed by Jones (1991 ) and Dechow and Dichev (2002 ). Our results indicate that formation of an audit committee reduces intentional earnings management but not accrual estimation errors. We also find differences in the associations between audit committee accounting expertise and the two earnings quality measures. Other audit committee characteristics examined are not significantly related to either earnings quality measure.     

Audit Committee Members’ Reputation Incentives and Their Effectiveness in Monitoring the Financial Reporting Process

We examine whether the reputation incentives of audit committee members are associated with their effectiveness in monitoring the financial reporting process. Prior research assumes that audit committee members allocate their effort proportionately across all memberships on which they serve. However, our findings suggest that audit committee members with multiple audit committee memberships tend to focus their attention on the memberships that provide them with the greatest reputation incentives. Specifically, firms with a larger proportion of audit committee members where the membership is the most prominent are associated with higher financial reporting quality and more effective monitoring of internal control. Additional tests reveal that audit committee members’ reputation incentives are driving our results rather than independent non-audit committee members’ reputation incentives. We conclude that reputation is a strong incentive for audit committee members, such that it influences their monitoring effectiveness over the financial reporting process.     

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.     

审计委员会特征与会计师事务所变更的经验研究

本文以会计师事务所变更为视角,探讨具备怎样特征的审计委员会才能有效履行其职责。研究表明:审计委员会的独立性和专业性与会计师事务所变更显著负相关;审计委员会的开会次数与会计师事务所变更没有显著关系,说明审计委员会的存在有助于减少会计师事务所变更。但在对会计师事务所变更的进一步研究中,我们并没有发现会计师事务所变是为了追求更高审计质量的进一步证据,也说明审计委员会对会计师事务所变更的影响仍然有限。这些研究结论为完善我国审计委员会制度提供了经验证据。
