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.     

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.     

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.     

External Auditor Reassessment of Client Business Risk Following the Issuance of a Comment Letter by the SEC

Abstract

Following Arthur Andersen's conviction for obstructing justice, auditors faced a one-time significant change in their regulatory environment because it was clear that (i) major audit partnerships could be closed and (ii) post Sarbanes-Oxley Act (SOX), regulators would take a far more attentive (aggressive) role. In response auditors considered whether the pricing of audits should be revised to take account of the increased risk of regulatory intervention and litigation. Obviously such re-pricing would need to be targeted at those firms for which the risks were greatest. One early warning signal of such events occurring is the issuance by the Security Exchange Commission (SEC) of a Comment Letter (CL). We investigate whether there is any evidence that if a client receives a CL this is used to re-price audit services. Specifically, we investigate whether issuance resulted in upward pressure on audit fees, and whether this effect was simply transient around the issuance period or alternatively persisted some years into the future. This research finds that after a client receives a CL, auditors adjust audit fees upwards in the period in which the CL is received. In addition it is shown that for subsequent periods in which the auditor does not spend time assisting the client respond to a specific CL, an initial rise in audit fee persists. This is consistent with the hypothesis that auditors reassess the reputation and litigation risk of the client on the basis of the SEC issuance of a Comment Letter.     

胁迫威胁下的审计独立性问题研究

Loss Aversion,Audit Risk Judgments,and Auditor Liability

Abstract

I investigate how different legal regimes affect auditor's effort and investors' investment decisions when the auditor is subject to probability weighting and loss aversion, which are two important characteristics of Prospect Theory. Probability weighting encourages an auditor to overrate the audit risk and the likelihood of damages leading to inflated audit fees which could help to explain the BigN audit-fee premium. With loss aversion, an auditor is sensitive to the risk of damage compensation and, thus, tends to exert excessive caution which also generates excessive audit fees. Consequently, investors may choose not to hire an auditor and, as a result, may forego an otherwise profitable investment. These effects are more intense with a strict liability regime than with a negligence rule because with the latter, the auditor is not held liable when due care has been exerted. This removes the risk of incurring losses. The paper highlights the robustness of the negligence regime when preferences are unobservable.     

客户资源控制权与审计师轮换的治理效应

审计师轮换是构建注册会计师审计秩序化格局以防范会计欺诈的重要监管手段。我国资本市场以行政权力和关系网络为主导的治理模式影响了会计师事务所的产权结构安排和资源配置模式,出现了客户资源控制权个人化的现象,致使我国监管政策的微观运行基础与欧美国家存在重大差异,同时也阻碍了会计师事务所的内部治理,从而说明我国审计市场存在审计师轮换的客观需求基础。为此,将审计师的私人人力资本转化为会计师事务所的组织资本是提高审计师轮换质量效应的重要路径。     

政府管制、事务所规模与审计意见——基于我国SEO管制的实证研究

结合我国特有的SEO管制环境,从制度变迁的视角动态地考察事务所规模对审计意见签发的影响及其相应的监管后果。经验数据表明,事务所规模对审计意见签发的作用程度会随着SEO管制环境的加强而得到强化,表现为小型会计师事务所在管制环境变迁后显著的不倾向于签发非标意见,而监管者对这一行为在统计上并没有如同变迁前一样进行有效的识别。本文的研究不仅为深入理解事务所规模对审计意见签发的作用程度受制度变迁的影响及其监管后果提供了直接的经验证据,也为当前我国证券市场的改革提供一定的政策启示。     

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.     

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.     

审计任期与审计独立性——持续经营审计意见的经验研究

以注册会计师是否因财务方面存在可能导致公司持续经营能力问题的事项或情况对上市公司出具持续经营审计意见作为审计独立性的衡量指标,分别从签字注册会计师任期与会计师事务所任期两个角度具体考察了审计任期与审计独立性之间的关系。结果发现,无论是注册会计师任期,还是事务所任期,审计任期越长,审计独立性就越低。这为我国已实施的签字注册会计师强制轮换政策的合理性提供了经验支持。     

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。     

审计师客户不匹配关系如何影响资本市场信息环境？——基于关键审计事项披露视角

新审计报告准则增加了披露关键审计事项的要求,以2016—2020年的关键审计事项文本数据为研究对象,考察了审计师客户不匹配关系对关键审计事项披露的影响。研究发现,向上的审计师客户不匹配关系显著提升了关键审计事项可读性、详细程度和数量,有助于优化资本市场信息环境;向下的审计师客户不匹配关系显著降低了关键审计事项可读性、详细程度和数量,无益于资本市场信息环境的改善。进一步分析发现,在向上的审计师客户不匹配关系中,审计师更倾向于清晰说明关键审计事项的披露原因,给出结论性评价,并且会披露更多的行业共性风险事项和公司特性风险事项。研究结论为完善关键审计事项披露制度、持续优化资本市场信息环境提供了有益借鉴。     

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 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.     

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.     

Internationalization and Auditor Choice

Prior research shows that internationalization increases information asymmetry and conflicts of interest between managers and outside investors, which lead to greater agency problems. Agency theory predicts a demand for higher quality auditors when agency problems are more severe. This study investigates whether the extent of internationalization influences auditor choice and whether audit quality has performance implications for internationalization. Using a set of U.S. firms from 2003 to 2009, we find the extent of internationalization positively related to audit quality. Furthermore, higher quality audits positively moderate the relation between internationalization and firm performance. Taken together, these results suggest that higher quality audit mitigates the agency problem associated with internationalization.     

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 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.
