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.     

Auditor–Provided Consultancy Services and their Associations with Audit Fees and Audit Opinions

This study examines the relationships between non–audit services fees (consultancy fees) paid to auditors and (1) audit fees, and (2) the occurrence of qualified audit opinions. The positive association between consultancy fees and audit fees is shown to be due to certain company specific events that generate a demand for consultancy services as well as requiring additional audit effort. Identified company specific events are mergers and acquisitions, new share issues, new accounting and information systems, new CEOs, and corporate restructurings. When these events are absent, there is no statistically significant relationship between audit fees and consultancy fees after controlling for company size. Companies that have relatively high consultancy fees are more likely to receive a clean audit opinion. This may be due to the non–audit work clearing up problem areas at the client company or it may be due to high consultancy fees impairing auditor independence. With the available data it is not possible to distinguish between these two reasons.     

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.     

审计费用的事前确定、异常审计费用与审计质量

实务中,我国部分上市公司年报审计费用采取事前确定方式,也就是在审计工作开展之前的董事会上确定。事前确定审计费用的动机何在,会产生什么样的审计后果?已有国内外文献尚缺乏这方面的研究。本文以2008～2017年全部A股上市公司为样本,通过实证考察审计费用事前确定方式对异常审计费用以及审计质量的影响发现:基于低价揽客或折价维持客户的经济动因,事前确定的审计费用显著偏低。进一步研究表明,在事前确定审计费用方式下,客户的审计质量更低。本文研究丰富和拓展了审计费用及审计质量决定因素的相关文献,同时也为监管机构规范审计费用确定方式提供了经验证据。     

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。     

注册会计师发展非审计业务探讨

本文在对比考察国内外注册会计师发展非审计业务的实践和遇到的问题后得出以下结论:会计师事务所超出审计范围从事会计服务和管理咨询服务等非审计业务,属于注册会计师职能的拓展;注册会计师有能力和优势从事非审计业务服务;非审计业务是一把双刃剑,它需要在政府的监管下规范发展。这些研究有利于进一步规范非审计业务的发展,促进注册会计师深度服务于中国经济发展。     

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's Engagement Risk and Audit Fees: The Role of Audit Firm Alumni

Abstract:  This study explores the effect of the association of audit firm alumni with their alma mater on audit prices. The tests indicate that there is a moderate reduction of up to 21% in the level of audit fee when alumni (i.e., former employees) of the incumbent audit firm sit on the client board of directors which is consistent with the engagement risk theory. This suggests that there is an 'alumni effect' in the market for audit services. The findings hold only in the large company segment of the market. The results are robust to different model specifications and alternative samples. The sample comprises all executive and non-executive directors who run the UK quoted companies and are simultaneously ICAEW qualified chartered accountants. The study's implications for the accounting profession and the regulators are also discussed.     

The Market for External Audit Services in the Public Sector: An Empirical Analysis of NHS Trusts

This study investigates the market for audit services in the UK National Health Service (NHS). The market has a number of interesting features, including the presence of the Audit Commission as a regulator, appointer and provider of audit services. Following a theoretical overview of audit pricing in the NHS, evidence is provided on the behaviour of private sector auditors in an environment where audit risk characteristics differ from the private sector. The research also investigates, for the first time in the public sector, the relationship between audit fees and non–audit (consultancy) fees. Comparisons are also drawn between audit fees in the public and private sectors in an analysis of audit fees by industry. Despite some key similarities, the study shows that a number of differences exist between private and public sector audit fee models. In particular, we find no evidence of Big 6 (or mid–tier) auditor premiums, but we do find a significant negative relationship between audit and consultancy fees providing support for the 'knowledge spill–over' hypothesis. In addition, the fees charged to trusts appear significantly lower than their private sector counterparts, despite trust auditors having additional duties to perform. Possible explanations for this finding are offered in the paper.     

An Empirical Investigation of Audit Pricing in the Public Sector: The Case of Greek LGOs

This paper investigates the associations between audit pricing and multidimensional characteristics of local governments by using a sample of Greek municipalities. The Greek institutional setting is interesting because it is politically pluralistic. Moreover, independent auditors appointed through a bid process exclusively perform the audits. Our results suggest a considerable variation on audit fees which is mainly driven by politically related factors indicating the importance of relevant theoretical anticipations in audit pricing in the public sector. Agency costs appear strong enough to explain audit pricing. We also confirm prior findings on the significance of audit complexity and size. Results also suggest that audit fees are reduced when an internal team dedicated to accrual accounting is appointed. Therefore, our conclusions offer practical implications for policy setters and regulators in the public sector in relation to audit quality.     

Audit Pricing of Shared Leadership

This study explores audit implications of shared leadership in client firms. Analyzing data from 2002 to 2013 of Korean listed companies, we find that auditors spend fewer audit hours and charge lower audit fees for clients with multiple CEOs. Additional tests reveal that the lower audit fees for co-CEO clients are likely attributable to reduced audit effort rather than to reduced hourly rates. We also document that firms with co-CEOs exhibit better-reporting quality than do firms with a solitary CEO. In sum, this article presents evidence that mutual monitoring via co-CEO appointments assures high-quality financial reporting of audit clients, and thus leads to reduced audit fees.     

Audit Fees, Non-Audit Fees and Auditor Going-Concern Reporting Decisions in the United Kingdom

The accounting profession has come under increased scrutiny over recent years about the growing number of non-audit fees received from audit clients and the possible negative impact of such fees on auditor independence. The argument advanced is that providing substantial amounts of non-audit services to clients may make it more likely that auditors concede to the wishes of the client management when difficult judgments are made. Such concerns are particularly salient in the case of reporting decisions related to going-concern uncertainties for financially stressed clients.
 This study empirically examines audit reports provided to financially stressed companies in the United Kingdom and the magnitude of audit and non-audit service fees paid to the company's auditors. We find that the magnitude of both audit fees and non-audit fees are significantly associated with the issuance of a going-concern modified audit opinion. In particular, financially stressed companies with high audit fees are more likely to receive a going-concern modified audit opinion, whereas companies with high non-audit fees are less likely to receive a going-concern modified audit opinion. Additional analyses indicate that the results are generally robust across alternative model and variable specifications. Overall, evidence supports the contention that high non-audit fees have a detrimental effect on going-concern reporting judgments for financially stressed U.K. companies.     

超额商誉、高管激励与审计收费

基于2011-2018年沪深A股上市公司样本,实证检验超额商誉对审计收费的影响以及高管激励的调节效应.研究表明:超额商誉提高了审计收费,且在民营企业更显著;而高管不同激励方式对超额商誉与审计收费的调节具有异质性:股权激励具有抑制作用,而薪酬激励具有增强效应;从作用机制来看,超额商誉通过增加经营风险和审计投入,进而提高审计收费.     

融资约束、审计费用与现金持有价值

审计费用和现金持有价值是公司财务审计研究领域的两个重要话题。审计费用高低所隐含的公司风险程度影响着投资者对公司增加现金持有量将产生积极还是消极效应的判断,会导致公司股票超额回报率的变化,进而也可能影响其现金持有价值,目前尚无相关的研究。本文以现金持有的边际价值模型为基础,引入审计费用和融资约束变量,对融资约束条件下审计费用与公司现金持有价值的关系进行研究后发现,过高的审计费用会降低公司的现金持有价值,审计费用增加得越多,公司的现金持有价值越低。进一步的分析发现,相对于其面临较高程度的融资约束时,公司面临较低程度的融资约束时审计费用对其现金持有价值的负向影响更为显著。     

The Effect of Corporate Status on External Audit Fees: Evidence From the UK

Abstract:  This paper simultaneously examines, for the first time, the determinants of external audit fees of UK companies drawn from the quoted sector (Main Market, the Alternative Investment Market and Ofex), and the unquoted sector (public and private limited companies). The paper also provides new evidence on the effects of corporate failure and the persistence of the big four and mid-tier auditor premiums across the public and private corporate sectors. After controlling for firm size, audit risk and complexity, we find that quoted and unquoted public limited companies have significantly higher audit fees than their private limited counterparts. Our estimates imply that relative premiums for market/corporate form are as follows: Main Market over AIM, 6.8%; AIM over Ofex, 19.5%; Ofex over unquoted plc, 15.5%; and unquoted plc over private, 16.7%. However, despite indications in prior US research to the contrary, we find no evidence that insolvent firms that failed were charged higher audit fees in the year preceding failure. A positive relationship is also found between audit and consultancy fees – a result that persists using an instrumental variables approach to control for endogeneity.     

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.     

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.     

Panel Cointegration Analysis of Audit Pricing Model

This paper addresses two issues that arise from testing and estimating cointegration in accounting research. The first issue is the failure to use more powerful cointegration tests by earlier researchers. This has led to the problem of low test power in the cointegration procedures employed in the earlier accounting literature. Another issue that has not received much attention in earlier studies of audit pricing is the endogeneity bias that arises from the endogenous nature of the regressors. Commonly used regressors such as auditee size and auditee complexity are endogenous and are often related to audit fees through a system of simultaneous equations. Endogeneity bias suggests that the conventional OLS estimators are biased.Using more powerful panel sample estimation procedures, we find that elasticities of total assets are in general under-estimated in the earlier studies when the conventional OLS method was used. We also find that the earlier studies tend to under-state the effects of the foreign subsidiary ratio and over-state the effect of the ratio of account receivables to total assets on audit fees.JEL Classification: C33, M41     

数字化转型对审计费用的影响研究——基于企业商誉的中介效应

依据2010—2022年中国A股创业板上市公司数据,运用多元线性回归模型探究数字化转型对审计费用的影响。结果显示,企业数字化转型进程与审计费用的增加呈正相关关系,这一关系在重污染行业尤为显著。进一步分析表明,商誉在企业数字化转型对审计费用的提升过程中具有中介效应。鉴于此,企业应加强精细化审计成本预见性与规划性,全面考虑数字化投资与审计成本之间的平衡,适时调整审计策略与资源配置,监管层需适时调整审计行业规则应对数字化转型。     

对外直接投资、控制风险与上市公司审计费用

本文在国家实施"走出去"战略的背景下,研究企业对外直接投资对审计费用的影响。研究以2007~2018年我国A股上市公司为样本,发现进行对外直接投资的企业,审计费用显著高于没有对外直接投资的企业,说明审计师能够识别因企业对外直接投资导致的审计风险的上升和审计成本的增加,并通过增加审计费用的方式予以补偿;且此差异不因产权性质和企业所在地市场化水平而异;采用改变样本量、PSM及多时点DID等进行稳健性检验后,研究结论保持不变。进一步分析发现,如果企业内部控制质量较高,控制风险水平较低,则对外直接投资与审计费用之间的关系会弱化,表明控制风险在对外直接投资与审计费用之间起到调节作用,且此作用仅在非国有控股及市场化水平较高地区的企业中显著。
