The Provision of Non-audit Services and the Pricing of Audit Fees

There have been a number of studies examining audit fees and this research has covered various nations. Recent legislation in Norway requires a company to disclose information on the audit fee and the fees for non-audit services paid to its auditor. Using this data, models of audit fee structure are developed. As with other studies, the size of the company is a major determinant of the audit fee. Payments for non-audit services are positively and significantly associated with audit fees; this relationship is difficult to explain although it parallels some research in the United States. Overall, the models explain about 75 per cent of the variability in audit fees.     

The determinants of audit fees—evidence from the voluntary sector

Given the growing demand for accountability in the public sector, there is a need to begin to investigate audit pricing issues in this sector. This study makes three contributions. First, it develops and estimates, for the first time, a model of audit fee determinants for the charity sector. As in previous private sector company studies, size, organisational complexity and audit firm location are the major determinants. A positive association between audit fees and fees for non-audit services is also observed. Charity sector factors of empirical significance include the nature of the charity (i.e., grant-making or fund-raising), its area of activity and the importance of trading income. Separate models for grant-making and fund-raising charities reflect the relative complexity of the audit of fund-raising charities. Second, the lower auditor concentration in the charity sector market, compared to the private sector market, permits a more powerful test of whether large firms and/or auditor expertise are rewarded with a fee premium. In the more complex audit environment of fund-raising charities, the results show that Big Six audit firms receive higher audit fees (18.5%, on average) than non-Big Six firms. Also, non-Big Six audit firms with charity expertise are rewarded with a fee premium over other non-Big Six firms. Finally, the study demonstrates that the charity audit fee rate is significantly lower than that of private sector companies; in fact it is approximately half. A change in the reporting of charity audit fees is proposed to reflect any element of ‘charitable giving’ by the audit firm.     

Auditor specialization, perceived audit quality, and audit fees in the local government audit market

Prior governmental research implies a positive relation between auditor specialization and audit quality, but the effect of specialization on audit fees is mixed. However, no single governmental study investigates the effect of auditor specialization on both audit quality and audit fees. Also, prior studies focus on either large- or small audit firms and often employ indirect proxies for audit quality. We study the effects of auditor specialization on perceived audit quality and audit fees. Our data represent both Big 5 and smaller audit firms and include three market-based measures of specialization. We survey 241 Florida local government finance directors and find that specialization is positively associated with perceived audit quality but not with audit fees. We also find that Big 5 auditors, often used as a proxy for higher audit quality in prior research, are not uniformly associated with increased perceived audit quality but consistently charge higher audit fees. Our results confirm a relation between measures of audit firm specialization and audit quality and raise questions regarding audit firm size and audit quality in the municipal sector. Our findings suggest that engaging specialized auditors may be good policy for many local governments.     

Changes in audit effort and changes in auditors’ disclosures of risks of material misstatement

This paper investigates whether auditors' year-to-year modification to risks of material misstatements (RMMs) in extended auditors' reports (EARs) are associated with changes in underlying audit effort, as proxied by changes in audit fees. We examine the dynamics of RMMs over time in terms of adding or dropping specific RMMs. Our main results show that, on average, audit fees increase more from the previous year's fees when more RMMs are added to the current year's EAR. This increase is partially offset by dropping RMMs that were disclosed in the previous year, but changes in audit fees are not significantly affected by dropping RMMs without adding new RMMs. Further analysis suggests the effect of added RMMs is attributable to “new” RMMs originating with the auditor and that added RMMs that were previously known, based on related disclosures in the prior year's audit committee report, do not significantly impact on changes in audit fees. Overall, our results suggest that changes in the choice of RMMs included in EARs reflect changes in underlying audit effort.     

The effect of small audit firms’ failure to remediate the PCAOB’s quality control criticisms on audit market segmentation

This paper examines the role of the Public Company Accounting Oversight Board (PCAOB) quality control inspection program on market segmentation of small firms’ audit services. Specifically, we investigate how non-remediation of quality control criticisms (QCCs) affects the supply and demand of low-quality audits. We find that remediation of QCCs improves audit quality for small accounting firms. However, some small accounting firms do not remediate QCCs (NR firms) and continue to provide low audit quality. We investigate how NR clients react to the disclosure of non-remediation of QCCs. We find that NR clients with low agency costs are more likely to retain NR firms after the disclosure of non-remediation. This finding is consistent with our expectation that voluntary QCC remediation creates a low-quality audit market segment for NR firms. Our findings suggest that the public disclosure of QCCs is not sufficient to remove low-quality auditors. Instead, NR clients use the disclosure of non-remediation of QCCs as a signal to sort themselves into segments based on their demand for audit quality. We are the first to study and find that PCAOB inspections, and specifically the voluntary nature of remediation and public disclosure of lack of remediation, create market segmentation.     

Non-audit services, auditor quality and the value relevance of earnings

This paper tests the hypothesis that there is an inverse relation between non‐audit services (NAS) provided by a firm auditor and the value relevance of earnings (measured as the earnings response coefficient) and that this relation is weaker for firms with Big 6 auditors. The hypothesis is based on anecdotal evidence and previous research that suggests that the provision of NAS by the external auditor is likely to adversely affect investors’ perceptions of the credibility of financial reports, and that Big 6 auditors, because of reputational capital and litigation costs, are likely to mitigate the adverse effects of NAS. Results using 840 firm‐year observations of Australian companies document a statistically significant inverse relationship between NAS and the value relevance of earnings, and this inverse relationship is weaker for Big 6 auditors, therefore supporting the hypothesis.

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.     

Auditor rotation and the appearance of independence: Evidence from non-professional investors

We examine the impact of audit firm versus partner rotation on non-professional investors’ independence-related perceptions, extending prior research on auditor rotation and independence in fact. Arguments for mandatory audit firm rotation continue to be made by regulators and investor groups based, in part, on the idea that firm rotation will incrementally strengthen independence in appearance relative to audit partner rotation. We report the results of two experiments. The first examines 5-year audit firm versus partner rotation under relatively weak or strong audit committees. We find no statistically significant difference in beliefs about how much of an income reducing audit difference management will record, or in beliefs about auditor independence, between the two auditor rotation conditions. On the other hand, we find that non-professional investors do believe more of the audit difference will be recorded, and the auditors will be more independent, under a strong audit committee than a relatively weak audit committee. The second experiment provides further evidence on audit firm versus partner rotation by examining a setting involving a 26-year audit firm–client relationship. Again, no statistically significant differences between the two auditor rotation conditions were found. These findings suggest that compared to audit partner rotation, audit firm rotation does not strengthen independence in appearance among non-professional investors and that non-professional investors recognize the value of strong audit committees.     

The effects of disclosing critical audit matters and auditor tenure on nonprofessional investors’ judgments

In an effort to provide more meaningful information to financial statement users, the Public Company Accounting Oversight Board (PCAOB) recently adopted sweeping changes to the audit report, requiring the audit firm to disclose whether or not it identified a critical audit matter (CAM) and its tenure with the client. To our knowledge, ours is the first study to explore how nonprofessional investors’ judgments are influenced by (1) the relative effects of a CAM disclosure versus a disclosure that the auditor did not identify a CAM, and (2) the disclosure of the audit firm’s tenure. We find that, relative to disclosing that no CAMs were identified, disclosing a CAM reduces investment intentions. We do not find a significant effect of tenure disclosure on investment intentions, despite evidence that participants attended to and understood the tenure manipulation. Concerning investors’ cognitive processes, we find that perceptions of both risk of material misstatement and management disclosure credibility mediate the effect of CAM disclosure on investment intentions, while perceived audit quality suppresses this effect. Our contributions include furthering the understanding of cognitive mechanisms through which CAM disclosure influences investment intentions, identifying a relatively unique setting in which perceptions of management disclosure credibility and audit quality move in opposite directions, and providing evidence that auditor tenure disclosure does not appear to affect investment intentions. Our findings should be of interest to regulators, auditors, issuers, and investors.     

Audit Firm Tenure and Audit Quality in a Constrained Market

We examine the relation between audit quality and audit firm tenure in the Iranian audit market, which is constrained by government policies that create intense competition for clients among many small audit firms. We develop arguments that these circumstances create cost pressures that entrench low audit quality and render auditors' plans more predictable to managers wishing to misstate their accounts. Using publicly available data for the audits of listed companies in Iran prior to mandatory audit firm rotation and the incidence of misstated financial reports identified by the Iranian Association of Certified Public Accountants Inspection Office, we find that the likelihood of a misstatement is lowest in the first two years of audit firm tenure. We also find that the likelihood of misstatement is not associated with the year preceding a mandatory audit firm rotation, suggesting outgoing auditor effort is not sensitive to the prospect of subsequent revelations of deficiencies. Although our results from a pre-mandatory rotation period show that frequent rotations appear to improve the financial reporting quality in our sample, we are wary of interpreting these results as support for the mandatory audit firm rotation policy in Iran. Rather, we suggest this is a peculiar consequence of deficiencies in audit quality inherent in the Iranian market.     

Do supply shocks in the audit partner labor market affect auditor choice? Evidence from a quasi-natural experiment

We examine whether supply shocks in the audit partner labor market induce clients to switch audit partners. We argue that audit partners in their early careers (i.e., junior partners) charge low audit fees to attract clients, which induces client firms to switch from senior partners to junior partners when there are more junior partners available. Utilizing the Big4 localization policy, we find that Big4 clients are more likely to replace senior auditors with junior auditors to cut costs after the policy. Furthermore, the results are mainly driven by clients who are charged high fees. Our empirical evidence enriches the understanding of auditor choice determinants and informs the ongoing debates surrounding new regulations for Big4 firms in China.     

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.
