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.     

Are the ‘Big Six’ ‘big’ in Belgium?

Studies in the United States, Europe and Australia have shown that the market for audit services is highly concentrated and largely dominated by the same ‘Big Six’ international audit firms. This paper measures the degree of concentration in the Belgian audit market through an empirical study of the number of professionally qualified auditors employed by each audit firm and some characteristics of their clients. Our calculations show that the concentration ratios, however measured, are low when compared with other countries, possibly due to the low value attached to the certification of financial statements by a professionally qualified auditor. This lack of importance can be explained by characteristics of the Belgian environment (e.g. a relatively passive capital market, dominated by a few large holding companies) which may induce companies to chose cheaper (domestic) audit firms. We also calculate Spearman rank correlations between the rankings of the audit firms based upon the different audit firm revenue proxies. All the correlations show it is of no importance which measure is used to rank audit firms.     

The changing public sector: from transition to transformation

This paper contributes to the empirical audit-quality literature and provides evidence on (the lack of) audit-quality differentiation in the private client segment of the Belgian audit market. Auditor size is used as audit-quality proxy. Prior evidence on audit-quality differentiation between Big Six and non-Big Six auditors in the private client segment of the Belgian audit market is mixed. In this paper we investigate whether these mixed results stem from the inability of the dichotomous Big Six/non-Big Six variable to capture auditor-size differences in a less concentrated audit market. To that end we examine whether alternative continuous measures of audit-firm size (i.e. auditor market share, number of audit-firm clients, number of partners in the audit firm, total assets and operating profit of the audit firm) have a constraining impact on earnings management in a large sample of privately held Belgian companies (n?=?1,302). Overall, we do not find evidence that is supportive of quality differentiation in the private client segment of the Belgian audit market.     

Enforcement Actions and Auditor Changes

In this paper, we examine whether the uncovering of erroneous financial statements by German enforcement agencies is related to subsequent auditor changes. We argue that enforcement actions are likely to reveal information about the client or its auditor, which might affect auditor choice by initiating an update of mutual expectations. Our empirical findings indicate that firms with erroneous financial statements indeed have an increased probability of subsequent auditor changes. Firms also tend to change from a non-Big4 auditor to a Big4 auditor in this situation, suggesting that clients increasingly seek the reputation and services of Big4 auditors. Big4 auditors in turn do not appear to refrain from taking over error-firms as new clients in the German setting, which is characterized by limited auditor liability. Additionally, auditor changes are more likely to occur before the public announcement of an error, indicating that firms take action as soon as the uncovering of an accounting error becomes sufficiently certain.     

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.     

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。     

从会计师事务所变更看审计质量一个实证分析

本文考察了2000年至2002年我国深圳证券交易市场变更会计师事务所上市公司的审计意见情况,并以此分析了我国会计师事务所的审计质量。结果发现,近年来我国的审计质量正在逐年提高,同时会计师事务所变更的事例有减少的趋势。但是,我国的审计质量仍未达到令人满意的水平,有许多问题还需有关监管部门给予关注。     

Auditors' Ability to Resist Client Pressure and Culture: Perceptions in China and the United Kingdom

Ongoing corporate scandal and audit failure raise serious concerns about the ability of auditors to resist client pressure. Based on a sample of 93 auditors from China and the United Kingdom (U.K.), we analyze the effect of specificity of accounting standard, level of auditor tenure, provision of management advisory services (MAS) and degree of audit market competition on perceptions of auditors' ability to withstand client pressure in audit conflict situations. We draw on cultural differences to explain differences in auditors' perceptions in the respective countries. Our findings are consistent with national cultural characteristics identified in the research literature. We find that U.K. auditors perceive specificity of accounting standards, auditor tenure, MAS and competition as less likely to affect decisions as to whether or not to accept clients' preferred accounting treatments than do their Chinese counterparts. Additionally while Chinese auditors perceive MAS and competition to be significant factors, they perceive accounting standard specificity and auditor tenure to be insignificant. For U.K. auditors, these results are reversed. The results may be relevant to international audit firms operating cross‐culturally and seeking to apply common audit procedures or codes of professional conduct in different national settings.     

Market Implications of the Audit Quality and Auditor Switches: Evidence from China

Independent audits enhance the credibility of corporate financial reports and assist investors to make rational decisions in the capital market. Nonetheless, the utility of the auditing function depends upon the quality of audits, which is determined by the independence and expertise of auditors. Hence, auditor choice and switch will not only affect an audit's quality, but will also influence decisions made by investors and other market participants. The purpose of this paper is to investigate how investors respond to the quality of audits and auditor switches in the Chinese context. Empirical results show that the quality of an audit and switching to a larger auditor have a positive (negative) impact on earnings response coefficients (ERCs) for firms with positive (negative) abnormal earnings. In contrast, switching to a smaller auditor has a negative (positive) impact on ERCs for firms with positive (negative) abnormal earnings. These results suggest that large auditing firms (Top 10) in China are perceived as more effective for curbing income-increased earnings management, which leads to higher (lower) ERCs for clients with positive (negative) abnormal earnings. Firms' switching to a larger auditor may signal high-quality earnings. Therefore, investors more often increase stock prices when firms have positive abnormal earnings and less often depreciate prices for negative abnormal earnings. Similarly, switching to a smaller auditor may signal lower earning quality, resulting in opposite market responses. In general, the empirical evidence suggests that audit information is valued by the capital market in China. Large auditing firms have been able to product-differentiate themselves within the Chinese stock market.     

审计师选择与业绩承诺精准达标——基于中国借壳上市公司的经验证据

在借壳交易中，对借壳方（非上市公司）财务报告执行审计的审计师可以是壳公司（上市公司）的现任审计师，也可以是新任审计师。以2011—2020年完成借壳上市并签订业绩补偿承诺的我国A股借壳交易案件为样本，检验借壳上市审计师选择对借壳公司业绩承诺实现情况的影响。研究发现，与保留壳公司现任审计师的借壳公司相比，借壳上市交易中选择新审计师的借壳公司更可能在业绩承诺期间精准实现业绩承诺，盈余管理是借壳交易中审计师选择影响借壳公司精准实现业绩承诺的作用渠道。此外，当业绩承诺补偿方式为股份补偿以及借壳交易双方为关联方时，借壳交易中选择新审计师的公司对业绩承诺精准达标的正向作用更加显著。进一步研究发现，借壳上市交易中选择新审计师的公司更可能在业绩承诺到期后经历业绩滑坡，且大股东更可能在锁定期结束后减持股票。结果表明，与保留壳公司现任审计师的借壳公司相比，借壳交易中选择新审计师的借壳公司的机会主义行为更严重。     

股权结构、治理结构与审计师选聘——基于委托代理理论的实证考察

本文以委托代理理论为基础,选择2002年深圳股市的484家上市公司为样本,考察了大股东控制的公司审计师选择行为。结果发现第一大股东持股比例越高,就越不聘请国际“四大”会计师事务所的境内合作所,以便实施其掏空行为;而设立审计委员会可以在一定程度上遏制大股东的审计师选择偏好;如果第一大股东是外资股,则更可能聘请国际“四大”会计师事务所的境内合作所,以求降低其代理成本。     

自愿性审计师变更原因与投资者反应

本文选取2001￣2004年发生自愿性审计师变更的公司作为样本,采用事件研究法考察投资者对审计师变更公告中所披露不同变更原因的反应。研究发现,市场对于不同原因的审计师变更反应存在差异,投资者根据变更原因判定审计师变更为好消息的反应显著大于判定其为坏消息的反应。由此可知,投资者对于披露的变更原因信息具有一定的识别能力,不同类型的审计师变更会影响公司的价值。监管部门强制披露审计师变更原因有助于提高市场有效性。     

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.     

企业会选择与竞争对手共享审计师吗?——基于经营范围相似度的分析

在选择最适合自身需求的审计师方面,企业会关注竞争对手的选择,并在享受审计专家服务与保护专有信息外溢之间寻求平衡。以企业的收入排名和经营范围的相似度衡量竞争对手,检验竞争对手间的审计师共享行为。研究发现,当行业内经营范围高度相似的两个企业互为竞争对手时,共享审计师的可能性较低;行业竞争激烈程度会放大竞争对手共享审计师的负向关系;但当外部审计师为审计专家时,会改变同行竞争对手不愿共享审计师的倾向;从经济后果来看,聘用同一会计师事务所的同行企业会有相似的经济决策。从财务层面构建衡量竞争对手的方法,验证竞争对手间的共享审计师问题,发现审计师不仅是财务报表的鉴证者,也是知识与资源丰富的信息中介与来源。     

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.     

Discretionary Accruals and Auditor Behaviour in Code-Law Contexts: An Application to Failing Spanish Firms

This study examines the relationship between earnings management and auditor behaviour in the pre-bankrupt client segment of the Spanish audit market. As proxies for auditor behaviour, we use type of audit firm (Big N/non-Big N) and type of audit report. In contrast to the USA, audit reports in Spain often include modifications other than a going-concern opinion. This allows us to study the relationship in more detail than is possible with US data. The results of our study show that discretionary accruals are negatively related to going-concern opinions but are positively related to reports modified for reasons other than going-concern problems. However, unlike Butler et al. (Journal of Accounting and Economics, 37, pp. 139–165, 2004) the negative relationship is explained not by liquidity survival tactics but by auditor conservatism. We find this conservatism not only in the value of discretionary accruals but also in the qualifications that accompany a going concern. In these cases GAAP violations have a much greater income effect and a stronger relationship with the reversal of manipulation accumulated over the years than with the manipulation introduced during the last year. Finally, our results suggest that Big N differentiation in a code-law country is context-specific and depends on the business risk parameter of the ‘audit risk model’. In particular, for high-risk firms, Big N auditors show a significantly lower level of discretionary accruals and a greater propensity to issue a going-concern opinion.     

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。     

Ownership concentration,modified audit opinion,and auditor switch: New evidence and method

This study investigates: 1) how does the ownership structure of listed firms influence the relation between their earnings management behavior and auditor opinion; 2) how does the ownership structure influence the relation between the auditor opinion and auditor switch. We find that the level of listed firms’ earnings management is positively associated with the propensity of being issued modified audit opinions (MAOs) by auditors when their ownership structure is highly concentrated. However, the issuance of MAOs is not associated with the auditor switch under such condition. On the contrary, a high level of earnings management is not associated with the propensity of being issued MAOs when firms’ ownership structure is less concentrated. Further, the issuance of MAOs may increase the likelihood of auditor switch. The empirical findings suggest that auditors may cater for the preferences of the real controller of listed firms when issuing audit opinions. Moreover, the “auditor opinion shopping” behavior by listed firms is also affected by listed firms’ ownership structure.     

地区环境、政治关联与审计师选择——来自中国民营上市公司的经验证据

以2005年—2008年的民营企业为样本,实证分析地区环境、政治关系与企业审计需求之间的相互关系后发现,在市场环境差的地区,企业更倾向于选择低质量的审计师、更有动机寻求政治关系,并且在审计师选择上,政治关联与地区环境有着相互替代的作用;而有政治关系的企业更倾向于选择低质量的审计师,选择低质量审计师的企业往往对应着更大程度的盈余管理。研究结果不仅丰富了政治关联的文献,而且对我国法制化建设有一定的启示。     

审计师轮换类别与审计结果——基于“关系”的视角

审计师强制轮换制度能够从制度上对审计师独立性给予一定程度的保证,而社会关系的存在会对审计师的独立性产生影响,但同时也能够增加前后任审计师工作交接的效率。以2007—2019年签字审计师轮换为样本研究发现,同一事务所内签字审计师的变更会使得后任审计师出具清洁审计意见的可能性提升,后任审计师审计当年发生财务重述的可能性较低,且可操纵性应计利润较低。但是,后任审计师获取的审计费用并没有显著降低。与不同事务所之间的签字审计师轮换相比,同一事务所审计师轮换情况下,由于更易进行信息共享与沟通,后任审计师的审计质量更高,且与前任审计师审计质量相比,后任审计师审计质量有所提升。
