Mandatory Audit Firm Rotation and Audit Quality

In a setting where mandatory audit firm rotation has been effective for more than 20 years (i.e. Italy), we analyse changes in audit quality during the auditor engagement period. In our research setting, auditors are appointed for a three-year period and their term can be renewed twice up to a maximum of nine years. Since the auditor has incentives to be re-appointed at the end of the first and the second three-year periods, we expect audit quality to be lower in the first two three-year periods compared to the third (i.e. the last) term. Assuming that a better audit quality is associated with a higher level of accounting conservatism, and using abnormal working capital accruals as a proxy for the latter, we find that the auditor becomes more conservative in the last three-year period, i.e. the one preceding the mandatory rotation. These results are confirmed using Basu's [1997. The conservatism principle and the asymmetric timeliness of earnings. Journal of Accounting and Economics, 24(1), 3–37] timely loss recognition model. In an additional analysis, we use earnings response coefficients as a proxy for investor perception of audit quality, and we observe results consistent with an increase in audit quality perception in the last engagement period.     

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.     

Do (Fe)Male Auditors Impair Audit Quality? Evidence from Going-Concern Opinions

Recent research indicates that there may be a relationship between the characteristics of the audit engagement partner and audit quality. In this paper, we examine the relationship between audit quality and the presence of a female or male audit engagement partner. We use the likelihood that an auditor issues a going-concern opinion (GCO), conditional on the client's financial situation, as an indicator of audit quality. Using a sample of 7105 financially distressed, private Belgian companies, we find that female auditors are, ceteris paribus, more likely to issue GCOs than male auditors. Our results also show that this effect is stronger when clients are either important (i.e. represent a material portion of the auditor's revenues) or high-risk (i.e. associated with increased uncertainties and risks). Collectively, these results indicate higher audit quality by female auditors.     

强制更换会计师事务所对审计质量的影响——对企业更换中天勤等事务所的实证分析

中天勤、沈阳华伦等5家会计师事务所2001年未通过年检被取消执业资格,他们的原有客户不得不改聘其他会计师事务所.该事件为强制更换会计师事务所提供了研究背景.以非正常性应计利润(DA)来衡量审计质量发现,在强制更换会计师事务所以后,这些公司的非正常性应计利润不降反升.进一步分析的结果显示,在正DA组,后任会计师没有调低那些公司的非正常性应计利润;而在负DA组,这些公司的非正常性应计利润在更换会计师以后反而增加了.研究显示,在中国这样一个极度分散的审计市场中,强制更换会计师事务所并没有带来大家预期的效果.     

Toward the Effect of Audit Quality on Earnings Management——Empirical Evidence from Manufacturing Enterprises Listed in Shanghai Stock Market

Nowadays, earnings management is a hot issue, but most of the researches focus on the incentives of earnings management and few of them refer to the effect of audit quality on earnings management. In this study, we directly examine the effect of external audit quality on earnings management by using discretionary accruals. We find that the discretionary accruals of non-dual audit companies are significantly greater than those of dual audit companies. We also find that clients of non-First Ten auditors intend to report greater discretionary accruals than those of First Ten auditors.     

审计师性别组成对审计质量、审计费用的影响——来自中国的经验证据

以2001年—2008年中国A股上市公司为研究对象,考察签字审计师性别和性别组成对审计质量和审计费用的影响后发现,女性组审计师可以在5%的显著性统计水平上增加负向的操纵性应计利润,审计师的性别组成与绝对的、正向及负向操纵性应计利润并无显著关系,女性组审计师及混合组审计师的审计费用都要显著高于男性组审计师。研究结论为审计师性别组成对中国审计市场的影响提供了重要的经验证据。     

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 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.     

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.     

Audit quality and the going-concern decision-making process: Spanish evidence

In this study, we attempt empirically to investigate the relationship between audit quality and the probability that a financially distressed company would receive a going-concern opinion. Auditor decision-making in the presence of going-concern uncertainties may be characterized as a two-stage process. The first stage is the identification of a potential going-concern problem and the second stage is to determine whether the particular company should receive a qualified going-concern opinion. A sample of 1,199 non-financial Spanish company-years has been obtained from the database issued by the Stock Exchange National Commission for the fiscal years ending between December 1991 and December 2000. The results indicate that audit quality (measured by the auditor's level of independence and knowledge) affects the probability that a financially distressed company would receive a going-concern opinion. This probability is influenced not only by the auditor's ability to detect financial uncertainties, but also by the auditor's decision-making as to what type of opinion should be finally issued.     

Governance Role of Auditors and Legal Environment: Evidence from Corporate Disclosure Transparency

In a sample of firms originating from 20 countries, we examine whether and how auditor size (our proxy for audit quality) associates with corporate disclosure transparency. While prior studies examine the relation between auditor size and several aspects of financial reporting quality (e.g. discretionary accruals, restatements, etc.), there is limited evidence on how auditor size relates to disclosure transparency. There is also mixed evidence on how auditor size relates to reporting quality in different legal environments. We find that auditor size is positively associated with disclosure transparency around the world and that the association is stronger in code law regimes than in common law regimes. The latter finding supports the view that audits play a greater governing role in weaker legal environments.     

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.     

The Effect of Arthur Andersen's Demise on Clients' Audit Fees and Auditor Conservatism: International Evidence

Using samples from 12 non‐U.S.A. countries, we find that following Arthur Andersen's failure in the United States of America, successor Big‐N auditors charged an audit fee premium for ex‐Andersen clients compared to existing clients and non‐Andersen switch‐ins. We show that this audit fee premium is not attributable to the Andersen switch‐ins having lower prior earnings quality or lower bargaining power than non‐Andersen switch‐ins. We also show that ex‐Andersen clients exhibit higher earnings quality after the switch than do ongoing clients and other switch‐ins. These results suggest that the audit fee premium is attributable to auditor conservatism. Furthermore, we find that risk assessments for ex‐Andersen clients are higher in countries with weak legal and extra‐legal institutions. We interpret this result as suggesting that the effect of lost auditor reputation is stronger when objective evidence of earnings quality is uncertain because of weaker supporting institutions. This is the first study to document a direct effect of countrywide institutions on audit risk assessment.     

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。     

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.     

CPA-Firm Merger: An Investigation of Audit Quality

It would be interesting to know how the theories and hypotheses in auditing developed for a mature economy work in an emerging market. This paper uses the merger of Diwan, Ernst & Young and J.T. Lai & Co., CPAs in Taiwan in 2000 as a target to study the effects of a CPA-firm merger on audit quality, measured by discretionary accruals. Diwan, Ernst & Young and J.T. Lai & Co., CPAs belonged to Big 5 and non-Big 5 CPA firms in Taiwan, respectively, before they merged. The magnitudes of the increased size and reputation caused by the merger are different between the two firms. Therefore, we also analyse whether the merger has different effects on audit quality of these two firms. The empirical evidence shows that after the merger, the discretionary accruals of the two firms' clients significantly decrease. In addition, the magnitude of the change is greater for the clients of J.T. Lai & Co., CPAs than for those of Diwan, Ernst & Young. The results are consistent with predictions of both size and reputation effect hypotheses.     

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.     

The Role of Overbilling in Hospitals’ Earnings Management Decisions

Abstract

This paper examines the role of overbilling in hospitals’ earnings management choices. Overbilling by hospitals is a form of revenue manipulation that involves misclassifying a patient into a diagnosis-related group that yields higher reimbursement. As overbilling allows hospitals to increase revenues without altering operations, affecting costs, or having to reverse such behavior in the future, I propose and find that overbilling reduces hospitals’ use of managing accruals or cutting discretionary expenditures. Next, I find that hospital managers prefer overbilling to managing accruals (cutting discretionary expenditures) when cutting discretionary expenditures (managing accruals) is constrained, and vice versa. Collectively, my findings suggest that overbilling is an important alternative manipulation tool in hospitals.
