The effect of mandatory auditor assignment and non-audit service on audit fees: Evidence from Korea

In Korea, regulators could assign auditors to firms. We investigate the relationship among audit fees, mandatory auditor assignment, and the joint provision of non-audit and auditor services in Korea. We find that assigned auditors charge significantly higher audit fees than freely selected auditors. We also find that the joint provision of non-audit and audit services does intensify the relation between auditor assignment and audit fees. Combined with the results of other studies that have shown that firms audited by assigned auditors report smaller amounts of discretionary accruals than firms audited by freely selected auditors, our results suggest the possibility that mandatory auditor assignment may improve auditor independence.     

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.     

The pricing of audit and non-audit services in a regulated environment: a longitudinal study of the UK life insurance industry

This paper studies the relationship between audit and non-audit service fees paid to the statutory auditor by UK life insurance firms, utilising an extensive panel-data sample set for the period 1999–2009. Consistent with a knowledge spillover (impairment of independence) hypothesis, we predict and find that audit fees are positively (negatively) associated with actuarial (tax service) fees. Additionally, our results indicate that regulatory changes enforced after 2004 deterred UK life insurance firms from purchasing non-audit services that are perceived to impair auditor independence. Finally, we find evidence concerning the inter-temporal determination of audit fees.     

The effect of disclosing audit quality control deficiencies on non-audit tax services: Evidence from Deloitte’s 2007 PCAOB Part II inspection report

We examine whether public disclosure of Deloitte 2007 PCAOB Part II report, which identifies quality control deficiencies related to audits of income tax accounts, affects Deloitte’s auditor-provided tax services (APTS). Using a difference-in-differences model, we document a 17 percent lower likelihood of Deloitte’s audit clients employing APTS relative to clients of other annually inspected firms when the report is made public. We also find that the dampening effect of publicly disclosing the Part II report on Deloitte’s APTS is more evident among audit clients paying higher non-audit fees to auditors and those with more complex tax planning. These results suggest that revealing income tax-specific quality control deficiencies prompts audit clients to revise upward (downward) their expected costs (benefits) of perceived auditor independence impairment (knowledge spillover) stemming from APTS. Overall, our study suggests that public disclosure of audit firm-wide quality control deficiencies pertaining to audits of income tax accounts imposes a collateral damage to the inspected firm’s non-audit tax services, thereby providing a more complete understanding of the consequences of the PCAOB’s communications about quality control deficiencies in Part II reports.     

UK investors’ perceptions of auditor independence

The auditor’s role in society is that of validating the truth and fairness of financial statements. If owners of organisations doubt the auditor’s independence, financial statements will lack credibility. This questionnaire-based study investigated how investors perceive three potentially independence-impairing auditor–client relationships: the joint provision of audit and non-audit services, an audit firm’s economic dependence upon a client and long-term relationships between auditor and client. The objective was to determine whether, after a series of high-profile corporate collapses, owners retain faith in the integrity of the auditor. The results suggest that economic dependence and the provision of non-audit services are perceived as greater threats to auditor independence than long-term relationships between the auditor and client.     

Consulting revenue sharing,auditor effort and independence,and the regulation of auditor compensation

The joint provision of audit and non-audit services by audit firms to their audit clients has posed a threat to auditor independence. To mitigate the independence problem, the US Securities and Exchange Commission (SEC) issued a regulation (SEC, 2003) that prohibits audit partners from receiving compensation for the sale of non-audit services to their audit clients. This study examines the effects of this regulatory change on the effort and reporting decisions of audit partners. We show that partners in an audit firm strategically change the firm’s liability-sharing rule. As a consequence, the regulation restores truthful reporting but has an undesirable negative effect on audit effort. The effect of the regulation on the welfare of the economy (defined as the total payoff to both audit firms and their clients) hinges on the tradeoff between the benefit of the regulation, which is derived from the inducement of truthful reporting, and the cost of the regulation, which results from less diligent audit work. We show that the regulation is more likely to increase the welfare in a strong legal regime (where the legal liability cost of auditor litigation is high) than in a weak legal regime.     

Perceived auditor independence and audit firm fees

Regulations requiring the disclosure of fees paid to an auditor for audit and non-audit services (NAS) respond to concerns that such payments are potentially detrimental to auditors' actual or perceived independence. Although empirical studies have failed to produce unequivocal evidence of detrimental effects on auditor independence, the actions of regulators, audit firms and companies are consistent with the belief that economic bonding generated by fees can impair perceived levels of auditor independence.

Using a sample of UK companies over a six year period to March 2006, we study perceived impairment of auditor independence by examining the relationship between levels of total relative fees (combined audit and NAS fees payable by a company to its auditor as a proportion of the audit firm's UK income) and market value. This paper's methodological innovation is its use of a valuation framework in this setting. A further contribution lies in dropping the assumption of linearity found in most prior empirical studies. We provide evidence that shareholders perceive a threat to auditor independence only at high total relative fee levels. At lower levels, total relative fees are positively related to company value. These results suggest that disclosure of NAS and audit fees are of relevance to investors, as is information about auditor income. Our results support the view that regulation by reference to the threshold at which total relative fees are perceived negatively is more consistent with investor preferences than prohibition of the supply of NAS by auditors to their audit clients.     

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.     

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 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.     

AUDITOR INDEPENDENCE,AUDIT QUALIFICATIONS AND THE PROVISION OF NON-AUDIT SERVICES: A NOTE

This paper presents the results of a study designed to investigate the question of whether there is the potential for an appearance of auditor independence impairment when higher levels of non-audit services are provided to audit clients. This question was investigated by analysing the audit reports for a sample of publicly listed companies over the period 1980 to 1989. The results of the analysis indicate that the auditors of companies not receiving an audit qualification of any type over the period derived a significantly higher proportion of their remuneration from non-audit services fees than the auditors of companies receiving at least one audit qualification. This result is driven by the non-Top 100 companies in the research sample. These findings could suggest that auditors are less likely to qualify a given company's financial statements when higher levels of non-audit services fees are derived. This could convey the view that the independence of the auditors of these companies may have been compromised.     

非审计业务对审计市场绩效的影响——基于会计师事务所业务结构的角度

以审计质量和审计收费作为审计市场绩效的衡量指标,从会计师事务所业务结构角度来考察我国注册会计师行业拓展非审计业务对审计市场所带来的影响。实证检验发现,相对于其他事务所而言,非审计业务规模越大和当年非审计业务规模较上年扩大的事务所,其审计质量越好,审计收费也越高。这说明在目前审计服务市场容量有限,竞争过于激烈的环境下,拓展非审计业务有利于增强审计独立性和提高审计收费,是改善行业执业环境的一个重要途径。     

Audit fee lowballing: Determinants,recovery, and future audit quality

Prior research on the link between lowballing (LB) of audit fees and audit quality is inconclusive. Using more recent data and an innovative design, we define LB engagements as those where the audit fee discount is at least 30 percent. We consider three research questions to understand the possible link between LB and audit quality. First, we investigate whether the two variables that are often associated with auditor independence in the literature—non-audit fees and client importance—are related to LB. Second, we test whether lowballing auditors recoup initial audit fee discounts in the future period. Lastly, we investigate the relation between recovery of audit fees and future audit quality. We find that non-audit fees in the first year of engagement are negatively related to the propensity to LB. LB is significantly positively related to client importance for client firms switching from a non-Big N to another non-Big N auditor while the relation is insignificant for client firms switching from a Big N to another Big N auditor. The results of non-audit fees and client importance indicate that economic dependence does not motivate audit firms to lowball. Further, lowballing auditors tend to recoup their initial fee discounts in subsequent periods via increases in audit fees. Using multiple measures of audit quality, we do not find a significant relation between recovery of audit fees and future audit quality. Overall, contrary to regulators’ concerns, our results suggest that LB does not impair audit quality.     

Non-audit Services and Auditor Independence: New Zealand Evidence

Abstract:  This paper examines evidence in New Zealand about whether auditors providing more non-audit services are less independent. Three sets of tests are used to address the issue. The first examines whether there is a relation between non-audit fees and audit fees, the second examines whether there is a relation between non-audit fees and audit report qualification or modification, and the third examines whether there is a relation between non-audit fees and stability of audit tenure. The results suggest a potential for the impairment of auditor independence in appearance when auditors provide non-audit services but no evidence of any impact on independence of mind.     

The impact of board of director oversight characteristics on corporate tax aggressiveness: An empirical analysis

This paper examines the impact of board of director oversight characteristics on corporate tax aggressiveness. Based on a 812 firm-year dataset of 203 publicly-listed Australian firms over the 2006–2009 period, our regression results show that if a firm has established an effective risk management system and internal controls, engages a big-4 auditor, its external auditor’s services involve proportionally fewer non-audit services than audit services and the more independent is its internal audit committee, it is less likely to be tax aggressive. Our additional regression results also indicate that the interaction effect between board of director composition (i.e., a higher ratio of independent directors on the board) and the establishment of an effective risk management system and internal controls jointly reduce tax aggressiveness.     

The effect of consistency in book-tax differences on analysts’ earnings forecasts: Evidence from forecast accuracy and informativeness

This study examines the relationship between the consistency of book-tax differences and the quality of analysts’ earnings forecasts. We find that the consistency of book-tax differences is associated with more accurate and informative forecasts. This suggests that the information embedded in the consistency of book-tax differences plays an important role in elevating the quality of analysts’ forecasts. Furthermore, the effect of consistency in book-tax differences on analyst forecast quality is greater for firms with noisier information environment. Finally, we find that the relation between consistency in book-tax differences and improvements in forecast accuracy and informativeness is stronger after the implementation of Regulation Fair Disclosure, which increased the role of public information in analysts’ forecasts.     

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.     

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 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.     

Non-audit fees, institutional monitoring, and audit quality

We posit that the effect of non-audit fees on audit quality is conditional on the extent of institutional monitoring. We suggest that institutional investors have incentives and the ability to monitor financial reporting quality. Because of the reputation concerns and potential litigation exposure, auditors are likely to provide high audit quality, when they also provide non-audit services to clients, particularly when clients are subject to high institutional monitoring. We find evidence that, as non-audit fees increase, audit quality (measured by performance-adjusted discretionary current accruals and earnings-response coefficients) reduces only for clients with low institutional ownership but not for clients with high institutional ownership. Our results are robust after controlling for auditor industry specialization, firms’ operating volatility, size effect, and potential endogeneity between institutional ownership and audit quality.
