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 effect of audit market structure on audit quality and audit pricing in the private-client market

This study examines whether audit market structure affects audit quality and audit pricing. We analyze two conceptually distinct dimensions of market structure: audit market concentration and client mobility. Focusing on the private-client segment of the Belgian audit market, we compare the pricing and quality effects of market structure between the segment of small and medium-sized (SME) clients and the segment of large clients to test how audit complexity moderates such effects. We find that market concentration impairs price and quality competition in the SME-client segment. Market concentration is unrelated to audit quality in the large-client segment, where we argue that concentration is endogenous to audit complexity. Furthermore, we find that client mobility stimulates price competition in both segments but improves audit quality only in the large-client segment. We interpret our findings as evidence that (a) audit market concentration impairs competition especially when audits have low complexity and that (b) the large-client market segment, characterized by higher audit complexity and higher market concentration, can also be price and quality competitive if clients are sufficiently mobile, and change auditors relatively frequently.     

Client importance and audit partner independence

We use data from Taiwan where audit partners are required to sign audit reports to examine whether audit partners compromise their independence for economically important clients. Uniquely, we include both listed and unlisted clients in audit partners’ client portfolios and separately study these clients for Big N and non-Big N auditors. We employ multiple proxies for auditor independence, including various abnormal accruals measures, the propensity of audit partners to issue modified audit opinions, and the probability that clients meet or just beat earnings targets. We fail to find evidence that Big N audit partners compromise their independence for economically important clients; however, we find such evidence for non-Big N auditors. Our results are robust to a battery of sensitivity analyses. While our inferences are limited to the Taiwanese capital market, our study may be of interest to market participants and regulators in other well developed capital markets.     

Audit market concentration,audit fees,and audit quality: A cross-country analysis of complex audit clients

Regulators around the world are concerned about the potentially harmful effects of high audit market concentration on audit pricing and quality. However, results in the overall literature have failed to reach consensus on this issue. We contribute to this debate by arguing that the audit market is segmented and that concentration in the Big 4 segment of the market leads to higher audit pricing. Accordingly, our analyses use international data and focus on concentration within the Big 4 group of firms across countries. We find that audit fees are increasing in our concentration measure for clients where the barriers to entry by competing auditors are higher, as proxied by client size, international operations, and IFRS use. Finally, we find evidence that audit quality is decreasing in Big 4 market concentration for these types of engagements. This indicates a wealth transfer from shareholders to audit firms when auditor concentration is high because these complex clients are charged more, but receive audits that are of lower quality.     

Joint Audit: Issues and Challenges for Researchers and Policy-Makers

Abstract

The publication of the European Commission Green Paper, ‘Audit Policy: Lessons from the Crisis’ in October 2010, has stirred up a lively debate on the role of joint audits. This literature review identifies and evaluates, for the benefit of future research and regulators, existing evidence about joint audits. We find limited empirical support to suggest that joint audits lead to increased audit quality, but some empirical support to suggest that joint audits lead to additional costs. Overall, this paper indicates that joint audit should be seen as a mechanism that is embedded in a broader institutional context and not be considered in isolation from other factors that might impact the audit market. The results indicate that various country-level characteristics are simultaneously at play. While joint audits can potentially enhance the audit market competition by allowing smaller audit firms to maintain larger market shares, the related impact on audit quality has not yet been clearly demonstrated and thus provides a promising avenue for future research.     

Busy auditors,financial reporting timeliness and quality

We investigate whether audit partners with multiple clients are able to complete their audits in a timely fashion, an important but largely unexplored area of academic research. One view is that having multiple clients increases the knowledge and experience of the audit partner resulting in a more efficient and therefore, quicker audit. On the other hand, having multiple clients may over-burden an audit partner resulting in a slower audit process and longer completion times. We find that audit partners with multiple clients take longer to complete their annual audit. More importantly, we also find that companies with busy auditors who take longer to complete their audits also have poorer levels of financial reporting quality. Additionally, in terms of consequences for busy auditors, firms with lengthy audit report lag switched their auditors the next year suggesting that busy audit partners may lose clients if their workload is excessive and they are not able to maintain audit quality. Our results are robust to alternative measures for both audit report lag and audit partner busyness and a range of endogeneity tests. We also undertake simultaneous quantile regression to assess changes in audit report lag depending on the number of audit clients per partner where we find preliminary evidence of a knowledge spill-over effect. Consequently, our results have implications for companies, audit firms, regulators and other key stakeholders.     

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.     

Audit pricing and auditor industry specialization in an emerging market: Evidence from China

In this paper we examine the determinants of audit fees by focusing on auditor industry specialization and second tier auditors in the Chinese market. We find evidence of Big 4 premiums for brand name as well as industry specialization in both the statutory and supplementary market. Big 4 industry specialists earn additional premiums in the statutory market as compared to non-industry specialists. We also find that market expansion did not provide the second tier auditors any price advantage. These auditors increased their market share mainly in the mid- and small-sized clienteles. Moreover, industry experience developed by the second tier firms may have helped them gain economy of scale and reduce service fees. This may be their strategy to win future clients that seek low-priced audits.     

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.     

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.     

Note on audit fee premiums to client size and industry specialization

This research note examines the impact of client size on the estimation of audit fee premiums in the Australian market for audit services. Previous research suggests that higher audit fees are expected for both larger clients and for industry specialization. We find that in the Australian market for audit services, the fee premium attributed to industry specialist audit firms is concentrated in the audit fees paid by the largest clients in each industry. One reason for higher fees paid by larger clients is the demand for additional audit services. We find higher fees for companies cross‐listed on US exchanges. We also find that fee premiums to auditors that are city‐industry leaders are strongly related to client size.     

Is mandated independence necessary for audit quality?

Independence (in fact as well as in appearance) is widely thought to be necessary for the quality of audits, and audit quality is often equated with independence. Private incentives to demand (and supply) independent certification of financial statements are thought to be insufficient, thus the need to mandate independence through regulation. This study presents data from a field experiment on the unregulated market for certification of baseball cards to assess the role of independence vis-à-vis other auditor attributes such as competence, price, and service on audit quality. In our field experiment, we examine prices of baseball cards sold on eBay with or without third party certification. In addition, the certifier was either independent or deeply immersed in providing other services to market participants. We find that market participants pay a significant premium for certified cards. Certifiers who are deeply immersed (and therefore apparently less independent) also provide higher quality service in the form of being stricter graders, command larger price premiums, and dominate in market share. Implications for independence and audit quality are discussed.     

Responsiveness of Auditors to the Audit Risk Standards: Unique Evidence from Big 4 Audit Firms

We examine the effect of changes in audit risk standards on the conduct of financial statement audits in a European setting. We investigate this by analysing the audit hours and audit fees for clients of Big 4 audit firms in Finland in 1996 and 2010. Our results show that audit firms became more sensitive to clients’ business risk due to the introduction of the new audit risk standards, with more audit hours allocated to owner-managed companies in 2010 than in 1996, and fewer audit hours allocated to low-risk clients in 2010 than in 1996. Also, the labour mix in the audit team changed for owner-managed companies, with a greater work load carried by junior auditors in 2010 than in 1996. Regarding the price of audit, we find an increase in audit fees for clients with high business risk, while audit fees remained at roughly the same level for low-risk clients. These findings should be of interest to the auditing profession and those involved in the development of auditing regulations.     

Opening Up the “Black Box” of Audit Firms: The Effects of Audit Partner Ownership on Audit Adjustments

Audit firms need to provide high-quality audits but they also need to please their clients. We argue that these conflicting incentives become manifest when comparing the incentive effects of equity ownership on engagement quality (EQ) reviewers and audit engagement partners. We predict that EQ reviewers monitor audit quality more closely when they hold greater ownership. In contrast, we expect that equity ownership has conflicting effects on the incentives of engagement partners because they need to please their clients as well as provide high-quality audits. Consistent with these predictions, we find that the associations between audit adjustments and partner equity ownership are (1) significantly positive for EQ reviewers, (2) significantly negative or insignificant for audit engagement partners, and (3) significantly more positive for EQ reviewers than engagement partners. Our findings suggest that larger ownership stakes motivate EQ reviewers to monitor audit quality more closely, whereas larger ownership stakes do not motivate engagement partners to deliver higher quality audits.     

An Assessment of the Provisions of Regulation (EU) No 537/2014 on Non-audit Services and Audit Firm Tenure: Evidence from Spain

On May 27, 2014, Regulation (EU) No 537/2014 was published in the Official Journal of the European Union. Aiming to enhance audit quality, the new regulation establishes important limitations to the selling of non-audit services by the audit firm to audit clients and a maximum tenure of ten years with the audit firm. However, it should be noted that the extant research has not consistently supported that non-audit services or long tenures impair the quality of audits. This research studies whether these provisions have been empirically associated with reduced audit quality for Spain. Because of its low litigation risk, the potentially negative impact of both non-audit services and tenure on audit quality should be clearly observed in the Spanish audit market. Nevertheless, we do not find significantly lower levels of audit quality associated with either non-audit services or long audit tenures. However, these results are conditional on the validity of using abnormal accruals to measure audit quality.     

An empirical investigation of the impact of audit and auditor characteristics on auditor performance

We use a unique and confidential database of 15,392 tax audits performed by the Croatian Tax Administration during the 2002–2006 period to examine the impact of task complexity, auditor experience, and auditor effort on audit performance. We provide external validation to prior experimental and analytical research showing that task complexity decreases while auditor experience and effort increase audit performance. We also extend this literature by examining the roles of task complexity and experience in moderating the impact of the effort on audit performance. We find that task complexity mitigates, while experience enhances the positive relationship between auditor effort and performance. However, we also find that auditor experience reinforces the positive effect of auditor effort on performance to a greater degree when complexity is high. Taken together, our findings provide new evidence on how audit and auditor characteristics impact audit performance, and new insight into how task complexity and auditor experience separately and jointly moderate the impact of auditor effort on performance.     

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.     

审计意见中的信息指标权效重构

代理人通过操纵信息来实现机会主义的行为已受到持久关注,本研究则考察在审计意见出具的过程中,审计双方不改变信息,但加重对自身更有利的指标的影响力的行为。以中国上市公司为样本的检验结果表明,会计业绩和市场回报都对审计意见具有解释力,当市场回报在同行业内相对于会计业绩的排序位置越差,其对审计意见的影响力也越大,同时,并没有证据表明,客户加强了表现较好的业绩指标的影响力。结果表明,表现较差的指标对审计意见的影响力得到增强,这可能源于审计方对执业风险的重视。进一步的测试表明,重构的效果随着公司业务复杂度的提升而下降,说明复杂的经营环境削弱了审计方的重构能力。综合结论为审计方的权效重构行为提供了经验证据。     

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.     

A study of auditor-client relationships and problems in the Bahraini audit environment

We report on a survey study of auditor-client relationship problems in an under-developed audit market in Bahrain. The study investigates client perspectives and views on important auditing process issues, value added audit activities for client organizations, and auditor rotation. Clients viewed high fees, excessive audit time requirements, difficulty in meeting auditor's requests, and audit personnel difficulties in understanding the business due to a lack of adequate audit professionals' experience as problems. From the audit firm perspective, the study explores audit client acceptance factors, independence issues, and common problems encountered with the clients. Auditor respondents indicated the major process problems to be associated with the client's culture, lack of access to information, and poor accounting systems. Auditors reported problems in collecting evidence. The audit process and evidence problems reported indicate possible audit quality problems faced by audit firms in Bahraini environment when conducting external audits, indicating the need for future research on auditor-client relationships in emerging economies.
