Non-audit Services and Audit Quality: Evidence from Private Firms

The purpose of this study is to examine the relationship between audit quality in private firms and the provision of non-audit services (NAS) – an issue that has rarely been considered in prior research. The threats to auditor independence are different in private firms compared to public firms. The same is true of the opportunities to use the same knowledge for audit and for NAS. Therefore, the effect of the provision of NAS on audit quality is also likely to be different. In this study, audit quality is measured by discretionary accruals, as well as by managers' perceptions of the extent to which the audit improves accounting quality. The regression analysis is based on 420 surveyed private firms in Sweden and suggests that audit quality is positively associated with NAS in general and accounting services in particular. The findings indicate that the joint provision of audit and NAS do not necessarily result in impaired auditor independence, but rather support the existence of knowledge spillover between the services.     

Auditor Independence,Current and Future NAS Fees and Audit Quality: Were European Regulators Right?

Abstract

European Union adopted the Regulation (EU) No 537/2014, which in practice prohibits the joint provision of audit and most types of non-audit services (NAS). Regulators presume that NAS fees weaken auditor independence and, as a result, impair audit quality. As the evidence at the European level does not support this view, the question of whether the new regulation will enhance auditor independence remains open. We examine the association between future NAS fees and audit quality by distinguishing among tax, audit-related and other services. We base the analysis on a sample of Spanish listed companies for the period between 2005 and 2016, finding a consistent negative association between future other NAS fees and audit quality. This suggests that the expectation of future purchases of this type of NAS may impair auditor independence. Conversely, for tax and audit-related services results are not significant. Taken together, results suggest that European regulators should seek for further evidence before banning NAS, as some of them may in fact enhance audit quality.     

Auditor independence in economies in transition: a study of Russia

The independence of auditors is regarded as key to their credibility as external verifiers of external financial statements. The requirement for external auditors to be independent of their clients when undertaking an audit is enshrined in the International Federation of Accountants' (IFAC) Code of Ethics and in the European Union's Eighth Directive. In the IFAC code this requirement is translated into various situations where observance of certain rules should ensure independence. As the countries of Central Europe and the former Soviet Union have drafted and implemented new laws on external audit, some of these auditor independence rules have been included in the new laws and codes of professional practice. Yet the rationale for the inclusion of these rules is not always clear, particularly given the different cultural and business contexts. In this paper, the authors have identified the auditor independence rule requirements that have been implemented into the laws and codes of practice in Russia. These requirements are then analysed against the economic, social and historic background in Russia, based to a large extent on interviews with auditors, enterprise management and users of financial statements, to generate questions about the efficacy of the auditor independence rules. This should provide relevant input to international and national bodies concerned with the drafting of rules relating to auditor independence in countries with different social and economic traditions.     

Changing the Institutional Framework of Statutory Audit: Internal Stakeholders' Perceptions of the Associated Benefit and Costs

This paper analyses the expected benefits and costs associated with changes to the institutional framework of statutory audits. We focus on five changes: Mandatory external audit firm rotation, auditor appointment by an independent regulator, a general ban on providing non-audit services, a ban on providing non-audit services to audit clients, and mandatory joint audits. We survey supervisory board members and management representatives from German companies to analyse how these changes affect the following beneficial attributes: Client-specific expertise and knowledge, general professional competence and expertise, independence and professional scepticism, and reputation. Our results show that none of the proposed changes is expected to increase the benefit of audits. A ban on non-audit services to audit clients is perceived to have the least disadvantageous effect, followed by a general ban on non-audit services, mandatory external audit firm rotation, appointment by an independent regulator, and mandatory joint audits. Although all changes are expected to increase auditor independence and professional scepticism, this increase is offset by a decrease in other beneficial attributes, particularly client-specific expertise and knowledge. Compared to supervisory board members, management representatives anticipate significantly larger decreases in the benefit of audits and significantly larger increases in costs.     

An Experimental Analysis of the Effects of Non‐audit Services on Auditor Independence in Appearance in the European Union: Evidence from Germany

The provision of non‐audit services by the statutory auditor may have a negative impact on auditor independence. Therefore, the European Union decided to prevent auditors from offering a significant extent of non‐audit services to audit clients. Prior research has revealed that different advisory services have different effects on perceived auditor independence. This could be caused by differences in number and intensity of independence threats (self‐interest, familiarity, self‐review, advocacy). Therefore, this experimental study investigates the effect of such threats on independence perceptions in the case of German individual investors. Multivariate analyses indicate that a high self‐interest and a high‐familiarity threat may impair auditor independence in appearance. On the other hand, our findings do not reveal a significant effect of an existing advocacy threat on investors’ trust in auditor independence. A negative effect of a self‐review threat is not directly confirmed. However, the provision of services with regard to internal controls, and thus the self‐review threat, interacts with the self‐interest threat. They potentially impact perceived auditor independence negatively when non‐audit fees are high. In contrast, no significant interactions with familiarity are found. Based on these findings, a general prohibition of non‐audit services does not seem to be necessary. On the other hand, a non‐audit fees cap might be reasonable.     

Review of empirical research on rotation and non-audit services: auditor independence in fact vs. appearance

Confidence in the processes of corporate reporting and auditing has rapidly decreased recently due to front-page accounting scandals in both the United States and Europe. The goal of audit regulations, such as the Sarbanes Oxley Act in the United States (US) and the 8th Directive in the European Union (EU), is to restore public trust in the auditing process. Along with other regulatory aspects, requirements related to audit partner rotation and bans on providing concurrent non-audit services were implemented to maintain auditor independence, both in fact and in appearance. However, the implementation of audit regulation implies that increased requirements are able to enhance the failed audit function. Empirical research should help to understand the impact of these two regulatory aspects and indicate their effectiveness in maintaining auditor independence. Thus, we outline the newest empirical research related to audit partner rotation and non-audit services and independence in fact or in appearance. Overall, we conclude that prior research does not point to one particular requirement that would most effectively restore trust in the audit function. Rather the existence of multiple threats to auditor independence might demand a combination of several requirements to maintain auditor independence. Thus, more research is needed to investigate the joint effects of different threats to auditor independence, e.?g., non-audit fees and audit partner tenure.     

Impact of renewable long-term audit mandates on audit quality

Anglo-American countries like the US and the UK allow companies to switch auditors every year. In contrast, some continental European countries restrict auditor switching by allowing only renewable long-term audit mandates. This paper aims to analyse the impact of renewable long-term audit mandates on audit quality. Audit quality is considered from the viewpoint of the external users of the financial statements. It is questioned whether renewable long-term audit mandates have an impact on the auditor's reporting behaviour and on auditor independence. This research is motivated by the lack of consensus in the literature on the impact of the length of the auditor client relationship on audit quality. Moreover, few empirical studies use publicly available secondary data in order to determine whether perceived threats to auditor independence actually compromise auditor independence. Therefore, our research methodology consists in the development of a logistic regression model in which the explanatory variables are measured using publicly available data. The results of the study suggest that long-term auditor client relationships significantly increase the likelihood of an unqualified opinion or significantly reduce the auditor's willingness to qualify audit reports. A significant difference was also found between the auditor's reporting behaviour in the first two years versus the last year of the audit mandate. Auditors are more willing to issue an unqualified audit report in the first two years of their official mandate than in the last year of their mandate. This could be an indication that the decision to renew the auditor's mandate is already taken and known to the auditor before he has issued his last audit report within his current mandate. The policy implications of these findings could be in favour of mandatory auditor rotation to maintain the value of an audit for the external users. However, given recent theoretic evidence on the adverse effects of mandatory auditor rotation, there is a need to develop alternative measures to safeguard auditors' independence.     

Research Forum: cross border comparisons Introduction

This paper investigates the effect of non-audit services on audit quality. Following the announcement of the requirement to disclose non-audit fees, approximately one-third of UK quoted companies disclosed before the requirement became effective. Whilst distressed companies were more likely to disclose early, auditor size, directors' shareholdings and non-audit fees were not significantly correlated with early disclosure. These results cast doubt on the view that voluntary disclosure of non-audit fees was used to signal audit quality. The evidence also indicates a positive weakly significant relationship between disclosed non-audit fees and audit qualifications. This suggests that when non-audit fees are disclosed, the provision of non-audit services does not reduce audit quality.     

胁迫威胁下的审计独立性问题研究

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.     

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.     

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。     

审计师行业专长与审计质量关系研究——基于客户规模视角

目前,我国国内学术界对于基于不同客户规模的审计师行业专长与审计质量关系的研究还不多。以2002年至2009年中国舞弊上市公司为研究样本,通过多元回归分析发现:审计师行业专长可以显著提高审计质量;在大客户市场上,审计师行业专长对审计质量提高的作用受到很大的限制和削弱,这可能是由于审计师对大客户审计时难以保持应有的独立性所致。     

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。     

The Provision of Tax Services by Incumbent Auditors and Earnings Management: Evidence from Korea

This study examines the associations between the provision of tax services by incumbent auditors and earnings management. We investigate whether three different effects of tax service provision play different roles in accounting practices. The three effects include the audit independence effect, the knowledge spillover effect, and the tax avoidance effect. If the provision of tax services by incumbent auditors harms auditor independence, firms may exercise greater earnings management (audit independence effect). However, if incumbent auditors gain incremental knowledge by offering tax services, the quality of their audit services could be enhanced, and therefore, reported earnings could be more conservative (knowledge spillover effect). If tax service fee leads to low taxable income, it could depress book income when book-tax conformity is high (tax avoidance effect). We find that the provision of tax services generally improves earnings quality by curtailing opportunistic accounting practices. The results also suggest that the negative association between the provision of tax services and discretionary accruals seems to be primarily driven by the knowledge spillover effect as opposed to the tax avoidance effect. Additional analysis is conducted in examining whether the tax avoidance effect exists in a sub-sample.

上市公司审计的失败应归因于注册会计师未能保持应有的独立性，而现有的上市公司审计法律关系三方主体中的委托人与被审计者合二为一是问题的关键。对此，审计业务转移、审计委员会委托、监管当局委托等多种重构思路被提出，但大多都有难以避免的缺陷。设立一个能代表众多审计报告使用者来进行审计委托并从中支付审计费用的上市公司审计基金是一个新的构想。     

The Empirical Research on Auditor Independence and Mandatory Auditor Rotation

Using, the method of correlation coefficient, this paper discusses the empirical relationship between audit tenure and audit opinion in annual reports in China A-share market and period of mandatory rotation of auditor. The research finds that the negative correlation between auditor tenure and non-standard unqualified audit opinion is statistically significant, and auditor tenure might impair his/her independence. To enhance auditor independence and improve audit quality, it is necessary to rotate mandatory auditor. The results also fred that consecutive auditing years should not exceed 5 years when the existing auditor has been the auditor of listed company, and mandatory rotation of auditor adapts to the rotation of CPA firms in charge of a client.     

European Market Reaction to Audit Reforms

Abstract

This paper investigates European stock market reaction to events associated with the proposed EU audit reforms that were ultimately implemented in 2016. These include, inter alia, mandatory audit firm rotation, prohibition of non-audit services, and fee caps. We find that investors react positively to the proposals, lifting aggregate market value by approximately €108,630 million. In cross-sectional analysis at both country and firm level, we find that these net benefits arise from the prohibition of non-audit services and the placing of a cap on total fees charged by the auditor. Furthermore, we find investors in firms with low earnings quality appear to perceive the greatest benefits from the proposed reforms.     

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.
