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。     

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.     

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.     

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.     

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.     

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 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.     

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.     

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。     

关系型交易对审计费用的影响——基于经营风险理论视角

关系型交易模式可能会在议价能力、关系专用性投资成本转换等方面加剧上市公司的经营风险,进而影响审计费用。已有研究主要集中于关系型交易对审计行为的影响,鲜有文献关注其中的作用机制。本文基于经营风险理论视角,选取2008~2017年沪深A股制造业上市公司的相关数据,实证分析了关系型交易对审计费用的影响,结果表明:关系型交易显著加剧了企业经营风险的集聚,进而提升审计费用,即经营风险在关系型交易对审计费用的影响中起到了中介作用。进一步研究,在区分了产权性质以及耐用品特征后,实证结果显示关系型交易与审计费用的正相关关系在非国有企业以及耐用品行业的企业中较为显著,为审计师进行合理审计定价提供了经验证据支持。     

Non-audit Service Fees and Audit Quality: The Impact of Auditor Specialization

We posit that the effect of non‐audit fees on audit quality is conditional on auditor industry specialization. Industry specialist auditors are more likely than nonspecialists to be concerned about reputation losses and litigation exposure, and to benefit from knowledge spillovers from the provision of non‐audit services. We find evidence that audit quality measured by increased propensity to issue going‐concern opinion, increased propensity to miss analysts' forecasts, as well as higher earnings‐response coefficients increases with the level of non‐audit services acquired from industry specialist auditors compared to nonspecialist auditors.     

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.     

审计机关购买社会审计服务决策研究

审计机关购买社会审计服务是基于承接单位所提供的审计服务质量可以达到预期、承接人员可以做到勤勉尽责这两个前提。通过服务购买,审计机关与社会中介机构缔结经济契约,弥补自身审计资源的不足。不同社会中介机构所能提供的审计服务在质量和价格上是有差异的;由于信息不对称,社会中介机构作为审计服务的供给方可能会选择性提供审计业务能力相关信息,审计机关可能无法优选目标而出现逆向选择现象。面对质量和成本双重目标约束,在探索协调路径的基础上,运用层次分析法,根据审计机关购买社会审计服务的特点,构建各指标的层次结构模型,从质量和成本两个维度进行量化分析,提出可行性方案,再进行决策,这种方法可以解决目前审计机关购买社会审计服务中可行性方案量化不足的问题。     

审计独立性与非审计服务

传统的审计服务曾经在相当长的时间内,在会计师事务所的服务结构中占有绝对优势.但是由于上市公司丑闻不断发生,尤其安然事件的爆发,引起政府相关部门、广大投资者、债权人及社会公众对非审计服务是否影响审计独立性这一问题的高度关注.本文介绍了非审计服务对审计独立性的正面影响和负面影响,并结合我国的现实国情,对我国发展非审计服务进行了必要性与可行性分析,讨论如何规范和发展我国非审计服务,如何保持注册会计师审计独立性,并着重论述了发展策略方面的问题.
