Audit committee financial expertise,corporate governance,and the voluntary switch from auditor-provided to non-auditor-provided tax services

A prime objective of the SOX is to safeguard auditor independence. We investigate the relation between audit committee quality, corporate governance, and audit committees' decision to switch from permissible auditor-provided tax services. We find that firms with more independent boards, audit committees with greater accounting financial expertise, higher stock ownership by directors and institutions, that separate the CEO and Chairman of the board positions, and with higher tax to audit fee ratios are more likely to switch to a non-auditor provider. Further, we document that firms are more likely to switch prior to issuing equity. We find no evidence that broad financial expertise on audit committees is related to the switch decision, suggesting that the SEC's initial narrow definition of expertise is more consistent with the objective of the SOX. Overall, our results suggest that accounting financial expertise and strong corporate governance contribute to enhanced audit committee monitoring of auditor independence.     

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 auditor IT expertise on internal controls

Material weaknesses in internal controls related to information technology (IT) represent unique threats to organizations. Utilizing the external auditor as an example of an externally observable governance mechanism, we investigate if firms with revealed IT internal control deficiencies employ a strategy of disassociation with their current auditor. Our tests show that prior evidence of disassociation strategies hold in both IT and non-IT contexts. Of particular focus to our study, we document a positive association between firms that report IT material weaknesses and subsequent auditor dismissals or switching. We next investigate the potential internal control benefits of switching to auditors with greater expertise in environments that emphasize the importance of IT. We argue that greater audit firm IT expertise promotes improved internal controls for their clients, especially those controls that are dependent on IT. We find that clients that switch to auditors with greater IT expertise, relative to their former auditor, have a greater likelihood of material weakness remediation within one year of reporting control weaknesses. Complementing these findings, we find that audit IT expertise is negatively associated with both non-IT and IT material weaknesses in an ex ante reporting setting. Prior literature takes a longstanding interest in both the incentive for developing auditor expertise and the effects of that expertise. We contribute to this literature stream by providing additional evidence related to a specific type of expertise.     

Corporate governance,SFAS 157 and cost of equity capital: evidence from US financial institutions

This study examines the association between fair value measurements and the cost of equity capital under different fair value valuation methods, and assesses the impact of corporate governance on this relationship for US financial firms. We find that firms’ cost of equity capital is negatively associated with more verifiable fair value assets and positively related to less verifiable fair value assets. Furthermore, the positive association between less verifiable fair value assets and the cost of equity capital is mitigated under better corporate governance. The differential impact between more and less verifiable assets becomes smaller for firms with stronger governance. Our findings contribute to the ongoing debate on fair value regulation by investigating the economic consequences of adopting Statement of Financial Accounting Standards No. 157, Fair Value Measurements (SFAS 157) and the importance of audit committee financial expertise on fair value reporting. We also provide evidence on the importance of board independence, internal control strength, auditor industry specialists, and audit committee financial experts in fair value reporting.     

On the effort-saving effect of audit committee–auditor interlocking

Using unique data on audit hours from China, this paper investigates the effort-saving effect of the audit committee–auditor interlocking (AClk). We find that AClk is negatively associated with audit effort without any deterioration in audit quality. The results suggest that AClk has an effort-saving effect through information sharing between interlocked audit committee members and auditors. However, auditors retain the effort-saving benefits of AClk without sharing them with their client firms. Further analysis shows that the effort-saving effect of AClk is more pronounced for client firms whose auditors have industry expertise, for client firms that share the same individual auditor, or for client firms that share audit committee members with financial expertise.     

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.     

Investor perceptions of the earnings quality consequences of hiring an affiliated auditor

The Sarbanes–Oxley Act (SOX) requires that firms wait 1 year before hiring an individual employed as a member of the external audit team. SOX’s intent is to reduce the perceived loss of auditor independence due to affiliated hiring. SOX also requires fully independent audit committees and disclosure of directors with financial expertise. Using a sample of financial executive hires during the pre-SOX period, we find that earnings response coefficients (ERCs) decline following hires of individuals recently employed by the firm’s external auditor, but ERCs do not decline following hires not recently employed by the external auditor. We also find smaller ERC declines following affiliated hires for firms with audit committee compositions consistent with subsequently imposed SOX requirements. Further investigation using measures of earnings quality suggests that differences in ERC changes are attributable to perceived, rather than real, changes in earnings quality following affiliated hires.     

Effects of audit committee chair characteristics on auditor choice,audit fee and audit quality

We investigate whether the characteristics of audit committee (AC) chairs are associated with decisions about auditor choice, audit fees and audit quality. Using hand-collected Australian data, firms with AC chairs who have longer tenure and multiple AC memberships across several boards are found to be more likely to choose Big 4 and/or industry specialist auditors, pay higher audit fees and have lower discretionary accruals. Those AC chairs with higher business qualifications are more likely to hire a Big 4 auditor, pay higher audit fees and have lower discretionary accruals, while AC chairs with professional qualifications are more likely to hire a Big 4 and/or industry specialist auditor. In contrast, firms with AC chairs who are executive directors are less likely to hire a Big 4 auditor and have higher discretionary accruals. Our findings contribute to the literature by documenting that various characteristics of AC chairs are important for enhancement of auditor selection and audit quality.

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。     

Effective board monitoring over earnings reports and forecasts: Evidence from CFO outside director appointments

Prior evidence that firms adjust their board structure following accounting restatements suggests that firms expect the board to effectively monitor the firm’s financial accounting system. However, little is known about signals firms use to identify monitoring weaknesses or the types of individuals firms appoint to improve the quality of monitoring. We expand on Ghannam, Bujega, Matolcsy, and Spiropolous (2019)’s evidence that firms appoint directors with accounting experience after financial fraud by investigating whether firms that file restatements or issue highly inaccurate earnings forecasts appoint individuals with CFO experience (i.e., a subset of accounting experts) to their audit committee. We find that firms are more likely to appoint an outside director with CFO experience to the audit committee when they have recently restated earnings and when they have higher prior management forecast error. We also find that the appointment of a CFO outside director to the audit committee is followed by a lower likelihood of restatement and more accurate management forecast. Together, our results suggest that firms respond to accounting failures by appointing outside directors with CFO experience. Thus, we provide insight into the signals firms use to identify weaknesses in the monitoring of the accounting function and the types of expertise firms value in addressing those weaknesses.     

An exploratory study of the effects of the European Union 8th Directive on Company Law on audit committees: Evidence from EU companies listed on the US stock exchanges

Member States in the European Union will be required to establish audit committees for all public-interest entities, according to the EU 8th Directive on Company Law. This EU 8th Directive creates a convergence of corporate oversight for both audit processes and financial reporting process and thus provides an opportunity to examine and contrast associations that exist among audit committee, board of directors characteristics with audit committee alignment, and the impact of such alignment on earnings management. Results of a logistic regression analysis suggest that firms with audit committees possessing greater financial expertise, with larger boards and more independent boards are less likely to engage in audit committee alignment while firms with audit committees possessing greater governance expertise are more likely to engage in alignment. In addition, we find that firms associated with audit committee alignment engage in less earnings management.     

The characteristics of firms subject to adverse rulings by the Financial Reporting Review Panel

This study presents evidence on the characteristics of firms judged by the Financial Reporting Review Panel (FRRP) as having published defective financial statements. Relative to a pairwise-matched control sample, FRRP firms are associated with weak performance in the defect year. In contrast, their performance in the post-defect period is indistinguishable from that of the control sample, suggesting that rather than being perennial underachieves, FRRP firms are average performers suffering temporary performance difficulties. FRRP firms are also less likely to have a Big Five auditor. Weaker evidence is also presented that FRRP firms are less likely to have an audit committee and a high proportion of outside directors. In contrast, their remaining governance characteristics are largely indistinguishable from those of the control sample. Moreover, there is no evidence that public censure by the FRRP leads to a higher incidence of executive turnover in subsequent years.     

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.     

How Effective Is Internal Control Reporting under SOX 404? Determinants of the (Non‐)Disclosure of Existing Material Weaknesses

We study determinants of internal control reporting decisions under Section 404 of the Sarbanes‐Oxley Act (SOX 404) using a sample of restating firms whose original misstatements are linked to underlying control weaknesses. We find that only a minority of these firms acknowledge their existing control weaknesses during their misstatement periods, and that this proportion has declined over time. Further, the probability of reporting existing weaknesses is negatively associated with external capital needs, firm size, non‐audit fees, and the presence of a large audit firm; it is positively associated with financial distress, auditor effort, previously reported control weaknesses and restatements, and recent auditor and management changes. These results provide evidence that detection and disclosure incentives play a role in whether existing material weaknesses are reported, which has implications for the effectiveness of SOX 404 in providing investors with advance warning of potential accounting problems.     

The effect of external audits of internal control over financial reporting on financial reporting for clients of Big 4, Second-tier,and small audit firms

The external audit of internal control over financial reporting (ICFR) is a very expensive and contentious aspect of the Sarbanes–Oxley Act (SOX). Larger public firms were first required to file a management report on and have an external audit of ICFR in 2004. Smaller public firms were first required to file a management report on ICFR in 2007 but are exempt from the audit requirement. Whereas most related prior research investigates the combined effect of management and auditor reports on financial reporting, this study examines the distinct effect of auditor reports on reporting quality. For companies audited by small auditors, we find evidence that financial reporting quality improves with an auditor report on ICFR. We find no evidence that auditor ICFR reports improve reporting quality for clients of Big 4 or Second-tier audit firms. Our study adds to the debate on the applicability of SOX Section 404 to smaller firms.     

Corporate Governance and Efficiency: Evidence From U.S. Property–Liability Insurance Industry

This study examines the relation between corporate governance and the efficiency of the U.S. property–liability insurance industry during the period from 2000 to 2007. We find a significant relation between efficiency and corporate governance (board size, proportion of independent directors on the audit committee, proportion of financial experts on the audit committee, director tenure, proportion of block shareholding, average number of directorships, proportion of insiders on the board, and auditor dependence). We also find property–liability insurers have complied with the Sarbanes‐Oxley Act (SOX) to a large extent. Although SOX achieved the goal of greater auditor independence and might have prevented Enron‐like scandals, it had some unexpected effects. For example, insurers became less efficient when they had more independent auditors because the insurers were unable to recoup the benefits of auditor independence.     

Internal and external influences on IT control governance

This study provides empirical evidence on the effects of internal and external governance on IT control quality proxied by IT related material weaknesses. IT control governance is defined as the leadership and organizational structures and control processes which ensure that the company's IT sustains and extends the company's strategies and objectives. Specifically, we examine the influence of senior management, the board of directors, and audit committees regarding IT control governance. We find that companies with more IT-experienced senior managers, with CIO positions or longer tenured CIOs and with higher percentages of independent board directors are less likely to have IT material weaknesses. We also provide partial evidence that more IT-experienced audit committee members are associated with less IT material weakness. The results suggest that both internal and external governance serve important roles in IT control quality.     

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.     

Auditor Independence: A Nonparametric Test of Differences Across the Big‐5 Public Accounting Firms

This small sample study provides additional evidence on the unsettled question of auditor independence: Does the provision of non‐audit services by an auditor compromise independence resulting in a poor quality audit? We also examine whether these findings vary across the “Big‐5” public accounting firms. Most prior studies addressing this question, using parametric approaches and various measures of audit quality, have reported conflicting results. Contrary to these studies, we use a non‐parametric approach and the probability of GAAP violation as a new measure of audit quality to address this question. Using data from a sample of Fortune 500 companies for the year 2000, we find that firms whose auditors provide substantial non‐audit services tend to have a higher propensity to violate GAAP. At the firm‐level analysis, we find that these results are more likely driven by few of the Big‐5 public accounting firms. For the remaining firms, the association between non‐audit services and quality of audit could not be established, primarily because of small sample size and lack of power in the test. Our main finding is consistent with other recent studies that provide evidence that the rendering of significant non‐audit services by auditors creates conflict of interest resulting in poor quality audits. Furthermore, our result of differences in these levels of association among the Big‐5 accounting firms represents a new finding, and suggests that there is a need for controlling them separately in research studies examining auditor independence.     

Audit committee characteristics and financial statement comparability

Financial statement comparability enables weighing the similarities and differences in financial performance between firms. Prior studies mainly focus on the role of accounting standards in the production of comparability, but the role of economic agents has been largely overlooked. We find that a firm's audit committee size and financial expertise affect its financial statement comparability. Financial information tends to be more comparable among industry peers when audit committees are larger and more members have financial and accounting expertise. The effect of audit committee expertise on comparability is stronger for firms with less independent and smaller boards, for firms with non-Big 4 auditors and for firms with CEOs serving as the chairperson of the boards.
