Audit Committee Financial Expertise,Litigation Risk,and Auditor‐Provided Tax Services*

The Sarbanes‐Oxley Act (SOX) greatly expanded audit committees' oversight responsibilities by requiring that they preapprove all non‐prohibited non‐audit services (NAS). Using data from 2003 to 2011, we find that tax NAS are significantly lower when accounting financial experts (ACT‐FEs) serve on the audit committee, suggesting that ACT‐FEs consider auditor independence risk, perceived and/or real, more than other members, including supervisory experts, to the point of not accepting any tax NAS, not even compliance. However, in firms with higher ex ante litigation risk, ACT‐FEs approve relatively more tax NAS than other members, suggesting that they accept the costs of a perceived lack of auditor independence from tax NAS in return for the potential benefits of increased financial reporting quality arising from tax NAS. Our analysis by subperiod (2003–2006 vs. 2007–2011) shows that this result is significant only in the second period. ACT‐FEs' differential evaluation of the trade‐off between the benefits and costs of joint audit and tax NAS provision between the two periods suggests the need for additional research in later post‐SOX years.     

Independent and joint effects of audit partner tenure and non-audit fees on audit quality

We examine the individual and joint effects of auditors’ non-audit services (NAS)/abnormal NAS fees and length of audit partner tenure on audit quality. Our results raise questions about the ‘one size fits all’ approach imposed by the current audit partner rotation requirement in Australia as a result of (1) a learning differentiation that we observe between Big 4 and non-Big 4 auditors and (2) higher discretionary accruals associated with non-Big 4 auditors. We find abnormal NAS fees to have a positive association with both absolute and positive (income-increasing) values of discretionary accruals for firms with short audit partner tenure. NAS/abnormal NAS fees are also negatively associated with the issuance of going concern opinions to financially distressed firms when partner tenure is short. In terms of policy implications, regulators are able to gauge the efficacy of the CLERP 9 reforms which currently impose a five year mandatory audit partner rotation requirement.     

Non-audit services provided to audit clients,independence of mind and independence in appearance: latest evidence from large UK listed companies

This paper investigates whether the provision of non-audit services (NAS) to audit clients impairs auditor independence of mind and independence in appearance. The main contributions of this paper are in terms of its timeliness with respect to regulatory changes, the simultaneous examination of both forms of auditor independence and the methodological innovation whereby it uses a variable derived from the level of abnormal audit fees as a moderating variable in order to capture the direct impact of the NAS fee level on auditor independence as well as how its influence is moderated by the level of unexpected audit fees. Our results indicate that auditor independence of mind is compromised by the size of NAS fees, particularly for clients who pay below the level of expected audit fee. The stock market perceives that auditor independence is compromised by NAS fees but, at the same time, additional tests indicate that there are benefits that accrue from NAS and, in particular, the relation between return and non-discretionary net income is increasing in NAS fees. The balance of evidence suggests that the European Union is correct in undertaking some reform of the auditing market.     

Audit committee characteristics and investment in internal auditing

Regulators and others recently highlighted the increasingly important role of internal auditing in supporting and interacting with the audit committee to ensure the integrity and quality of financial reporting. Likewise, one of the roles of the audit committee is to oversee the quality of monitoring mechanisms implemented by the firm, which includes the internal audit function. However, our understanding of the relationship between the audit committee and internal auditing is limited. We fill this void by providing the first empirical evidence of the association between audit committee characteristics and the investment in internal auditing. Our analyses, from a sample of 181 SEC registrants, suggest that the investment in internal auditing (internal audit budget) is negatively related to the presence of auditing experts on the committee and the average tenure of audit committee members, but positively related to the number of audit committee meetings (a proxy for audit committee diligence). These observations suggest potential complementary and substitution effects between the audit committee and internal auditing, and thus raise important implications for future research.     

Audit Firm Tenure,Non‐Audit Services,and Internal Assessments of Audit Quality

We use data from internal assessments of audit quality in a Big 4 firm to investigate the impact of audit firm tenure and auditor‐provided non‐audit services (NAS) on audit quality. We find that first‐year audits receive lower assessments of audit quality and that quality improves shortly thereafter and then declines as tenure becomes very long. Partitioning our sample between SEC registrants and private clients, we find that the decline in audit quality in the long tenure range is attributable to audits of private clients. For audits of SEC registrants, the probability of a high quality audit reaches its maximum with very long tenure. We also find that audit fees are discounted for first‐year audits but auditor effort is higher than in subsequent years. We find no association, on average, between total NAS fees and audit quality in the full sample but observe that total NAS fees are positively associated with quality for SEC registrants and negatively associated with quality for privately held clients. Our findings are important for regulatory policies related to audit firm tenure and auditor‐provided NAS.     

The effects of audit firm rotation on perceived auditor independence and audit quality

Our study explores loan officers’ perceptions of auditors’ independence and audit quality under three experimental audit firm rotation scenarios. We use a case experiment with a between-subjects design to determine whether rotation of the audit firm impacts financial statement users’ perceptions of auditor’s independence and quality. Findings based on 212 useable responses indicate that loan officers do perceive an increase in independence when the company follows an audit firm rotation policy. However, the length of auditor tenure within rotation fails to significantly change loan officers’ perceptions of independence. Findings also indicate that neither the presence of a rotation policy nor the length of the auditor tenure within rotation significantly influences the loan officers’ perceptions of audit quality.     

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.     

Independent audit committee members’ board tenure and audit fees

An independent audit committee is an audit committee on which all members are independent directors. This study examines whether independent audit committee members’ board tenure affects audit fees. On the basis of the prior literature, we formulate an unsigned hypothesis. This is because on the one hand, long board tenure audit committee members (defined as members with board tenure of 10 or more years) have greater incentives to protect their reputational capitals by purchasing increased audit effort, which positively affects audit fees. On the other hand, audit pricing reflects audit committee quality. Long board tenure audit committee members may have less need for increased audit effort because they can effectively oversee the financial reporting process themselves, which negatively affects audit fees. We find that audit fees are negatively associated with the proportion of long board tenure directors on the independent audit committee, consistent with the notion that audit committee members’ long board tenure results in lower audit effort.     

Characteristics of non-audit services and financial restatements in Malaysia

Various types of purchased non-audit services (NAS) and their recurring nature affect the likelihood of financial statement restatements in Malaysia. Based on 953 firm-year observations during the period 2007–2009, evidence of a negative relationship between non-audit fees and financial statement restatements is provided. The purchase of both tax-related and audit-related NAS decreases the likelihood of restatements. Recurring (as opposed to non-recurring) tax-related and audit-related NAS are negatively and significantly related to the likelihood of restatements. These findings support our hypothesis that both types of NAS and their recurrence provide knowledge spillover, which enhances audit and financial reporting quality. When considering institutional settings, we find that politically connected firms are more likely to require financial restatements than non-politically connected firms, while audit committee independence and the purchase of tax-related, recurring tax-related and other NAS decrease this likelihood. The purchase of audit-related and recurring audit-related NAS and non-recurring other NAS decreases the likelihood of restatements for non-politically connected firms.     

On the Relationship between Audit Tenure and Fees Paid to the Audit Firm and Audit Quality

Abstract

We investigate the impact of audit firm tenure, partner tenure, audit fees, fees for non-audit services and total fees on audit quality, as measured by discretionary accruals. Our sample consists of Spanish non-financial public companies for the years between 2006 and 2013. Results indicate that audit quality increases with audit firm tenure but decreases with partner tenure. Moreover, the level of fees paid to the audit firm seems to have a negative impact on audit quality, which is mainly driven by fees for audit services. In this regard, we do not observe any significant relationship between fees for non-audit services and audit quality. Our results also show that the negative relationship between either long partner tenures or high fees and audit quality does not occur when the tenure with the audit firm is long. Therefore, long audit firm tenures do not only seem to involve higher audit quality ‘per se’, but also moderate the negative effects of partner tenure and audit fees on audit quality. The results of this study, which are robust to several sensitivity checks, may be relevant for the current debate on auditor rotation and the joint provision of audit and non-audit services.     

Audit Partner Tenure and Independence in a Low Litigation Risk Setting

We investigate whether long audit partner tenures impair auditor independence, as proxied by the opinion of the audit report, with a sample of Spanish companies for the period: 2002–2010. The Spanish audit market constitutes an ideal setting in which to address this issue, as it is characterized by unusually lengthy engagements with the audit firm. The motivation relies, on the one hand, on the current discussion about the necessity to reinforce the independence of auditors and, on the other hand, on the very limited available research at the partner level. The main result is the lack of significant effects of partner tenure on independence. This finding is robust to various checks. Unlike prior research, we also address the joint effects of firm and partner tenure on independence. Results indicate that partner tenure does not compromise independence, even under long or extremely long audit firm tenures. These findings might have some interesting policy implications, in particular for the intense current debate on auditor rotation regimes which is taking place within the European Union.     

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。     

Audit report information content and the provision of non-audit services: Evidence from Spanish lending decisions

This study examines whether auditor economic independence affects the information content of going concern audit reports in the European setting. We conduct an experiment where 80 experienced Spanish loan officers from the second largest European commercial bank review a loan request under two lending scenarios: (1) a potential borrower receiving an unqualified but modified going concern opinion, and (2) a potential borrower receiving a qualified going concern opinion. Auditor economic independence, measured by the provision of non-audit services (NAS), is manipulated (absence vs. presence of significant NAS). We find that a qualified going concern audit report is interpreted as a primary warning signal (death penalty). However, the provision of NAS acts as a second order mechanism that only activates loan officers’ professional skepticism in the case of an unqualified but modified going concern report scenario. Therefore, we find evidence suggesting that the potential negative impact of a perceived lack of auditor independence depends on the nature of the audit report. Our findings have important implications for the European regulator, which is currently considering establishing an auditor independence regulation framework similar to that in the United States of America.     

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。     

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.     

审计委员会治理与审计意见

本文从审计委员会的存在性、独立性和勤勉程度三个方面,将审计委员会与审计师规模、异常审计收费、审计师变更等结合起来考虑,探讨审计委员会治理对上市公司年报审计意见类型以及不利审计意见改善和审计意见恶化的影响。研究表明,相对于审计委员会的存在性,审计委员会的独立性和勤勉程度对外部独立审计师审计判断及其所出具的审计意见的影响更为显著;在结合考虑审计师规模、审计收费、审计师变更等相关因素的前后均可以发现,在董事会中设立审计委员会并切实提高审计委员会的独立性和勤勉程度,不仅有助于提升上市公司财务报告的质量,而且亦有助于在一定程度上对管理层的审计意见购买行为进行有效的制衡。     

The interaction effects of firm and partner tenure on audit quality†

This paper investigates the impact of firm and partner tenure on audit quality, where audit quality is proxied by discretionary accruals. We study a sample of Spanish listed companies between 2005 and 2011 and address both the individual and the interaction effects of firm and partner tenure. Our study is motivated by the current debate, particularly intense at the EU level, on the impact of the auditor rotation regime on the quality of auditing. We find that, without considering the interaction effects, firm and partner tenure do not seem to play a relevant role as determinants of audit quality. Importantly, the interaction of firm and partner tenure shows stronger effects on audit quality than both forms of tenure separately considered. Finally, our analysis suggests that audit quality is maximized when medium firm and partner tenures interact. However, results for the interaction variables are sensitive to the accruals estimation method.     

Non‐audit Services and Auditor Independence Depending on Client Performance

We posit that the effect of non‐audit fees on auditor independence in Korea is based on audit client performance. Further, we suggest that an audit client with low performance has an incentive to purchase non‐audit services (NAS) from an incumbent auditor to facilitate earnings management and steer accounting practices in a preferred direction. We find evidence that as non‐audit fees in Korea increase, auditor independence is reduced only for low‐performing audit clients. Thus, unconditional prohibition of NAS seems unnecessary. Regulators and policymakers should examine the motivation for purchasing NAS, particularly among audit clients with poor performance.     

Do political connections affect the role of independent audit committees and CEO Duality? Some evidence from Malaysian audit pricing

This study examines whether political connection to firms affects the association between audit committee independence and demand for higher quality audits. In line with Carcello et al. (2002), our findings show that there is a positive association between audit committee independence and audit fees thus supporting the hypothesis that more independent audit committees demand higher audit quality. However, we find that this relationship is weaker for politically connected (PCON) firms suggesting that the independence of audit committees in Malaysian PCON firms may be compromised. Additionally, we provide evidence that PCON firms that have CEO duality are perceived by audit firms as being of higher risk than CEO duality firms without political connection.     

Conservative Reporting and the Incremental Effect of Mandatory Audit Firm Rotation Policy: A Comparative Analysis of Audit Partner Rotation vs Audit Firm Rotation in South Korea

In this paper, we take advantage of Korea's unique experiment with mandatory audit firm rotation (MAFR) and mandatory audit partner rotation (MAPR) to ascertain their influence on audit quality, proxied by conditional conservatism. Overall, we find that the implementation of MAFR did not have the desired effect. Firms that adopted MAFR demonstrate higher levels of conservatism in previous periods under MAPR (or compared to voluntary adopters). Furthermore, we find that audit tenure increases conservatism levels consistent with the auditor expertise hypothesis. However, whilst evidence suggests MAFR decreases audit quality on the whole, we find that firms that switch from non‐Big 4 to Big 4 auditors demonstrate higher conservatism because Big 4 auditors are more likely to demand conservative accounting practices, consistent with Big 4 audit firm knowledge superiority. Overall, the results suggest that MAFR's negative effect on audit quality can be mitigated by Big 4 auditor supervision.
