Audit Fees in a Joint Audit Setting

Abstract

This paper uses the uniqueness of the French audit environment to conduct an in-depth study of audit pricing issues associated with the requirement to hire two independent auditors (joint audit). I use a model derived from Simunic's [(1980). The pricing of audit services: Theory and evidence. Journal of Accounting Research, 18(1), 161–190] seminal work to examine to what extent audit fees are influenced by the number of Big 4 joint auditors (zero, one, or two). After controlling for well-known drivers of audit fees that are specific to audit client firms (size, complexity, and risk), for governance characteristics and for auditor selection, the paper shows that the decision to hire two Big 4 auditors as joint auditors does not require the payment of a higher Big 4 premium compared to the choice of one Big 4 auditor paired with a smaller auditor, other things being equal. The choice of two Big 4 auditors thus appears to be a rational economic choice for large and international firms.     

事务所转制效果存在差异吗？——原因与后果

借助理论模型将会计师事务所转制对审计质量及审计收费的影响纳入一个整合的分析框架,推导出影响转制效果的关键因素：除审计师法律责任的增加程度以外,客户经营风险以及转制前审计质量水平也同样影响审计质量及审计收费的提高。基于2007—2015年中国A股上市公司数据,在控制了客户经营风险之后进行实证研究,结果表明审计质量及审计收费的提升确实在初始审计质量较低的中小型事务所样本中更加显著。进一步研究发现,在事务所转制的过程中及完成后,更多的审计客户从中小型事务所转换为前十大事务所,且这种客户流动趋势在异常审计收费较高的样本中更加显著。     

审计关系错配、盈余质量与整合审计收费

以2012—2015年沪深主板A股执行整合审计的上市公司为研究样本，基于整合审计背景探讨审计关系错配与整合审计收费，研究发现大所对小规模客户给予整合审计收费折扣；小所对大规模客户给予整合审计收费折扣。进一步研究发现，基于财务报表审计与内部控制审计的知识溢出效应及联动机制，执行整合审计有助于审计师识别公司管理层的盈余管理行为。     

Legal Liability,Government Intervention,and Auditor Behavior: Evidence from Structural Reform of Audit Firms in China

This paper investigates how legal liability influences audit quality and audit fees, particularly in the presence of government intervention. Since 2010, all Chinese audit firms were required to transform from a structure of limited liability company (LLC) to limited liability partnership (LLP), which removes the cap on the liability exposure of negligent auditors. By adopting this natural experiment, we document the following findings: first, after audit firms reorganize as LLPs, auditors are more likely to (1) issue modified audit opinions and going-concern opinions, (2) constrain clients’ earnings management, and (3) charge a premium in audit fees, which suggest that exerting unlimited legal liability on negligent auditors improves both audit quality and audit fees. Second, the effect of the LLP adoption is more pronounced when auditors are from local audit firms, and clients are controlled by local governments. Further analyses suggest that the stock prices of clients positively react to the reform event, which indicates that LLP adoption improves the overall value of audits. In summary, our empirical findings are consistent with the argument that legal liability is able to effectively shape auditor behavior in emerging markets where the other institutional mechanisms are relatively weaker and government intervention is heavy.     

商业模式创新与审计收费——基于线上销售的视角

考察企业线上销售这一商业模式创新对审计收费的影响，基于2009—2020年我国全部A股上市公司的年报数据，利用Python语言构建企业开展线上销售的度量指标，实证研究发现,企业开展线上销售会使得审计收费显著增加,该结论在经过一系列稳健性检验后仍然成立。从机制检验结果来看，线上销售增加了审计风险，导致审计师采取更多的应对措施，从而提高了审计收费。异质性分析结果表明，“四大”事务所、具有行业专长以及具有较高信息技术水平的审计师审计会削弱线上销售对审计收费的正向影响。总之，厘清了线上销售这一商业模式创新对上市公司审计收费的影响及作用机制，加深了关于商业模式创新对企业经营及审计行为影响的认识，同时也为推动审计行业转型发展提供了有益启示。     

The future international tax environment and European tax harmonization: a personal view

This study examines whether the decision to voluntarily (i.e. without a statutory obligation) employ two audit firms to conduct a joint audit is related to audit quality. We use separate samples and empirical designs for public and privately held companies in Sweden, where a sufficient number of companies have a joint audit on a voluntary basis. Our empirical findings suggest that companies opting to employ joint audits have a higher degree of earnings conservatism, lower abnormal accruals, better credit ratings and lower perceived risk of becoming insolvent within the next year than other firms. These findings are robust to the use of a propensity score matching technique to control for the differences in client characteristics between firms that employ joint audits and those that use single Big 4 auditors (i.e. auditor self-selection). We also find evidence that the choice of a joint audit is associated with substantial increases in the fees paid by the client firm, suggesting a higher perceived level of quality. Collectively, our analyses support the view that voluntary joint audits are positively associated with audit quality in a relatively low litigious setting both for public and private firms.     

Sustainability reporting quality and post‐audit financial reporting quality: Empirical evidence from the UK

This study examines whether firms that appear to exhibit high sustainability reporting quality are less likely to engage in earnings management activities, thereby delivering financial information that is more transparent and reliable than that delivered by firms that do not produce high‐quality sustainability reports. I also investigate whether the association between sustainability reporting quality and post‐audit financial reporting quality is conditional on audit effort. Analysis of data drawn from FTSE 350 companies covering 2007 to 2018 indicates that firms that produce high‐quality sustainability reports are significantly and negatively associated with earnings management metrics. More importantly, this association is moderated by audit effort, measured by audit fees, suggesting that sustainability reporting quality reflects factors considered by auditors in their audit risk assessment practices. These results remain robust after several sensitivity analyses. I conclude that firms that devote more resources to producing high‐quality sustainability reports are likely to demonstrate an overall commitment to quality that alleviates auditors' concerns about the opportunistic use of sustainability reporting and reduces business risk, thereby reducing the effort auditors expend to verify financial reports.     

Audit Team Attributes Matter: How Diversity Affects Audit Quality

How audit teams are structured and function plays a crucial role in determining the level of audit service quality. Despite this claim, little empirical research has been conducted on this effect. Using private data from two of the Big 4 audit firms, we fill this gap and document how diversity of audit teams influences audit quality. By combining the existing work in psychology and sociology with that in auditing, we develop our model by arguing that teams are composed not simply of single auditors but of sub-teams of individuals whose various combinations affect team performance. Starting from this premise, we study how the diversity of audit teams in terms of the different mix of work assigned to staff, seniors, managers, and partners influences audit quality and how this effect varies depending upon years of tenure. We also show that the proportion of leading auditors characterized by a common educational background and the percentage of female leading auditors affect audit quality. As an additional analysis, we examine how team diversity affects audit efficiency. The same elements found relevant for audit quality also affect audit efficiency.     

The international firms as new entrants to the statutory audit market: an empirical analysis of auditor selection in Greece, 1993 to 1997

This paper investigates choice of statutory auditor in Greece in the five years subsequent to the 1992 liberalization of the audit market. We analyse auditor choices by 205 companies which, by 1997, represented almost 90% of companies listed on the Athens Stock Exchange. We find that the level of shareholdings by foreign shareholders is positively associated with choice of a Big Six versus any other auditor both immediately after liberalization in 1993 and still in 1997, indicative of the role of the Big Six in providing audit credibility in the eyes of international investors. In addition, Big Six auditors strengthened their position in the finance sector and, outside the finance sector, among larger companies over the period studied. We also find that in both 1993 and 1997 Big Six firms were distinguished specifically from the second-tier international firms, consistent with the view that, in post-liberalization Greece, companies by their choice of auditor appear to be distinguishing Big Six firms from all others but not between second-tier international firms and local auditors. These findings shed light on the hitherto unresearched area of which companies Big Six auditors target in order to gain market share when they are new entrants in an environment radically changed by regulatory reform. In addition the research extends the auditor name brand reputation debate by its finding that, in post-liberalization Greece, second-tier international firms appear to be distinguished from the Big Six but not from the local audit firms.     

家族企业国际化对审计收费的影响研究

以我国2010—2020年沪深A股上市家族企业为研究样本,实证检验家族企业国际化与审计收费之间的关系。研究结果发现,家族企业国际化程度的加深会使得审计收费提高。代际传承和家族董事席位分别在两者之间发挥正向和负向调节作用。机制检验表明,家族企业开展国际化经营增加了企业的经营风险,提高了审计师对于风险的评估,从而导致审计收费的提高。进一步研究发现,家族企业国际化与审计收费之间的正向影响在不具有海外背景高管的企业以及不存在国有持股的企业中更为突出。研究结论为从审计师视角加强对家族企业国际化的监管提供理论依据和经验证据。     

The Impact of the Big 8 Mergers on Market Power: Evidence from the Hong Kong Market

This study examines the impact of the Big 8 mergers on market power in an audit market where the merging firms have little presence. Audit fee changes for each merger participating firm are identified and fee changes for several post‐merger years are examined. The pre‐merger differential market power between the merging and non‐merging long‐established Big 8 firms (Price Waterhouse and KPMG Peat Marwick) in Hong Kong provides a unique opportunity to examine whether the mergers could help the merging firms to increase their market power. The results are consistent with the hypotheses that the audit fees of the merging firms were significantly lower than that of the non‐merging, long‐established Big 8 firms before the mergers, but the audit fees of the merged firms increased significantly to a level comparable with that of the latter group after the mergers. In addition, the market share of the merged firms increased significantly after the mergers. However, no association is found between market concentration and market power. Overall, the results show that the Big 8 mergers have helped the merged firms increase their market power and market share in the Hong Kong audit market where they had little presence.     

The impact of litigation risk on the association between audit quality and auditor size: Evidence from China

We examine whether audit quality varies across different sizes of CPA firms under high or low auditor‐specific litigation risk exposure. We measure audit quality by the issuance of modified audit opinions and the audit fees charged to clients, and we use the organizational form of CPA firms as the proxy for auditors’ litigation risk exposure, where a partnership (limited liability) CPA firm represents a high (low) litigation risk exposure. Built on Choi, Kim, Liu, and Simunic's (2008) theoretical framework, we hypothesize that the litigation risk exposure of CPA firm moderates the association between auditor size and audit quality. Our results show that when the auditor's liability is capped (i.e., registered as a limited liability form of CPA firm), larger size CPA firms are associated with higher audit quality when compared to smaller size CPA firms. However, this positive association between auditor size and audit quality disappears for audit firms that are subject to high litigation risk exposures (i.e., registered as a partnership form of CPA firm). Our research provides new insights on the impact of auditor‐specific litigation risks on the relation between audit quality and auditor size. In particular, we show that only when auditor‐specific litigation risk is limited, do large CPA firms appear to perform higher quality audits than small CPA firms.     

Audit Market Response to PCAOB Censures of US Big 4 Firms

Abstract

Subsequent to the first-ever Public Company Accounting Oversight Board (PCAOB) censure of a US Big 4 firm (Deloitte) in December 2007, there were two other PCAOB US Big 4 firm censures as of 2016 year-end. We examine whether these two post-2007 PCAOB censures of US Big 4 firms conveyed new information to the audit market. For both censures, we find little or no evidence of any change in the factual audit quality of the censured firm over a three-year window surrounding the censure. Our findings suggest that the quality control deficiencies (identified during inspection of specific audit engagements) that triggered the PCAOB censure were isolated occurrences rather than systemic to the firm at large, i.e., the censures do not imply an impairment in the US Big 4 firm's overall factual audit quality. We also find that the negative response of investors and audit committees documented in prior research for the 2007 Deloitte censure disappeared for the later US Big 4 firm censures. Given that the PCAOB inspects (and can censure) non-US auditors who audit US-listed foreign companies, our findings are of potential interest to regulators, investors and audit committees outside the US.     

真实活动盈余管理影响审计师的风险决策吗？

以2000—2012年我国上市公司为样本,分析并检验客户公司的真实活动盈余管理对审计师风险决策的影响。研究发现：客户公司的真实活动盈余管理程度越大,审计师出具非标准审计意见的概率越大、审计收费越高,但和审计师变更没有显著关系。进一步研究还发现：在纵向上,随着法律制度不断完善,审计费用、非标准审计意见的概率和真实活动盈余管理程度之间的关系更敏感;在横向上,审计收费策略和非标准审计意见策略之间存在替代效应。     

客户关系变动提高了审计费用吗？

在全球供应链不断发展的形势下，稳定的供应链关系愈发重要。从审计师风险应对视角探讨客户关系变动是否以及如何影响审计费用。实证结果表明，客户关系变动显著增加了审计费用。机制检验发现，客户关系变动使审计师加大审计投入并感知到更高的审计风险，进而收取更高的审计费用。进一步探究客户关系变动的原因及其对审计费用的影响后发现，客户自身面临财务困境时引发客户关系变动，提高了审计费用;但当企业经济政策不确定性较高时却降低了客户关系变动，从而降低审计费用。基于事务所层面和企业层面的异质性检验还发现，客户关系变动与审计费用的正向关系主要体现在高资质事务所、客户集中度较高和治理水平低的企业中。研究结论为探讨客户关系变动的经济后果提供了新的证据和视角，对当下中国如何进行供应链风险管理具有启示意义。     

A descriptive analysis of audit price changes in the UK 1991–95

This paper examines changes in the audit fees of quoted public limited companies in the UK during the period from 1991 to 1995. After controlling for changes in the size, complexity and risk of auditees, it is shown (based on a logarithm audit fee model) that the audit market experienced a 9.7% reduction in inflation-adjusted fees over this five-year period. The results also provide evidence of overall fee reductions by each of the Big Six. On closer examination, a mixture of fee increases, decreases and no changes were observed for auditees of the Big Six and for the groups of medium-sized and small audit firms investigated. These results, which pertain to a period when market concentration increased markedly (Beattie and Fearnley, 1994; Peel, 1997; Pong, 1999), offer some amelioration of the concerns of the purchasers of audit services that, in general, audit fees will rise in response to an increase in dominance by a few large firms.     

Audit committee effectiveness and the audit fee

The UK is the only major country within the European Union the majority of whose listed companies have formed audit committees composed of non-executive directors to monitor financial reporting, the external auditors, and internal control strength. The adoption of audit committees in contrast to the approach in Europe has arisen despite the lack of evidence on their effectiveness even in the USA and Canada, where they have been mandatory since the 1970s. This paper seeks to establish whether audit committees are effective in ensuring audit quality by protecting the auditors from fee cuts which might affect audit quality, and signal tighter internal controls which help to reduce audit time and hence audit fees. The problem is that the audit committee may be expected to exert a two-way pressure on audit fees. To the extent that audit committees should enhance audit quality, partly by ensuring that audit hours are not reduced, an audit committee may be expected to increase total audit fees. At the same time, an audit committee may reasonably be thought to be a proxy for internal control strength. Ceteris paribus, companies with strong internal controls may be expected to pay lower audit fees than those with weak internal controls. Our paper argues that the ‘quality’ aspect of the audit can be captured through a dummy firm size variable, whilst the internal control aspects can be captured through dummy risk and complexity variables. The hypotheses examined are that size related audit fees are higher in companies with an audit committee; and that risk- and complexity-related audit fees are lower in companies with audit committees. The hypotheses are tested by developing a regression model for audit fees of a sample of the companies which comprise the FT-SE 500, with variables being included for the presence or absence of an audit committee. The results show that the relationship between size-related audit fees and the presence of an audit committee is positive and statistically significant, but that although there is a negative relationship between risk- and complexity-related audit fees and the presence of an audit committee, the relationships are not conclusively significant. The findings provide support for the contention that audit committees are at least partially effective in preventing reductions in the audit fee to levels where the quality of the audit may be compromised.     

会计师事务所合并、审计市场结构与审计定价

以2006年至2009年初发生的8起"强强联合"会计师事务所合并案为研究对象,分析合并发生前后审计市场结构与审计定价的变化后发现:随着会计师事务所合并案的增多,市场结构呈现出市场集中度增加以及大所之间竞争更为均衡的特点,国内本土所的市场力量在逐渐增强,但与国际"四大"之间还存在着十分明显的差距。从单变量检验来看,合并后会计师事务所对同一客户的审计收费较合并前显著增加,但在控制其他影响审计定价的因素后,合并因素对审计定价虽仍有正向作用,但是在统计上并不显著。     

Investor legal protection,capitalized development costs,and audit fees: A cross‐country analysis

Our study explores the association between capitalized development costs and audit fees. International Accounting Standard No. 38 stipulates the discretion to capitalize the development costs of internally generated intangible assets. We find a positive association between capitalized development costs and audit fees, which reflects auditors’ concern that managers may use the discretion of development cost capitalization to manipulate earnings. Moreover, this positive association is mitigated by stronger investor legal protection because stronger investor legal protection alleviates the earnings management concern from capitalized development costs. These results suggest that country‐level legal regimes affect auditors’ perception on client firms’ accounting choices. Our study contributes to the literature exploring how legal regimes affect auditor behaviors.
