监管政策、审计师变更与后任审计师谨慎性

本文以我国2001～2002年出台的相关审计监管政策为例,讨论审计监管对审计师变更和后任审计师谨慎性的影响。由于证监会2001年发布的《公开发行证券的公司信息披露编报规则第14号—非标准无保留审计意见及其涉及事项的处理》(以下简称14号文)增强了非标审计意见之于上市公司的不利后果,因此可能推动了机会主义审计师变更的增加。我们发现,在14号文出台后,前期非标审计意见同审计师变更的正相关关系变得更为紧密,且大所向小所的审计师变更频率显著上升。但是,没有证据表明,相比于未变更公司而言,变更公司的后续审计意见改善程度更高。并且,在2000～2002年,后任审计师针对变更公司的谨慎性有逐渐增强的趋势,这意味着2002年中注协关于审计师变更的监管政策可能发挥了一定的积极作用。     

诉讼风险、审计师变更与审计意见改善

本文对企业陷入诉讼纠纷后变更审计师购买审计意见的行为后果进行考察,研究发现,后任审计师能充分关注客户诉讼事件带来的审计风险,对审计意见购买行为进行抵制,不清洁审计意见的出具概率增加,审计意见并没有改善.进一步区分审计师变更方向后,结果显示升级、平级和降级变更审计师均不能改善审计意见.本文结论表明当前审计市场监管,对审计...     

审计师变更之管理层与审计师博弈：模型与抉策

审计师的变更具有经济后果。管理当局通过变更审计师，购买有利的审计意见或是通过提出变更审计师威胁审计师的独立性，都将有损审计质量。本文通过构建管理层与审计师的博弈模型，分析可能影响其行为决策的因素，以期对我国审计师变更监管政策的制定存所帮助。     

盈余管理、事务所客户资源控制权的归属与审计质量——来自中国证券市场的经验证据

与西方市场仅能观察到事务所变更不同的是,中国资本市场还同时提供了审计师变更的佐证。基于此,本文应用新制度经济学中的资产专有理论,从审计师和事务所两个角度,分析了中国证券市场特有的审计师/事务所变更行为,并结合盈余管理和审计意见进一步分析这种行为的原因和后果。文章通过对比签字审计师离开事务所并带走客户的公司与签字审计师离开事务所没有带走客户的公司后,发现在审计师跳槽之前,公司的盈余管理越强,越会跟随审计师到新的事务所,表明客户资源的控制权归审计师而非事务所所有。并且,我们还发现,这类公司在审计师变更前的审计质量更差。本文的研究丰富了审计理论的研究手段和现有成果,并对于规范审计师行为和提高审计独立性具有积极的理论价值和现实意义。     

国外关于审计委员会的实证研究回顾

国外对审计委员会的实证研究(一)审计委员会特征与审计师变更根据蓝带委员会的报告,审计委员会的一项重要职能是确保外部审计师的独立性,特别是外部审计师与管理当局就有关会计处理以及审计意见类型发生分歧时,审计委员会应该站在客观、公允的立场上解决二者之间的冲突,确保审计师出具客观公允的审计报告。许多学者在研究审计师变更时发现,与管理当局的意见分歧是导致审计师变更的一个重要原因(Chow,1982;Stephens,1996)。Carcello和neal也发现,当公司审计委员会独立性很低时,审计师很少给财务上陷入困境的客户出具非持续经营报告,因为管…     

审计委员会治理与审计意见

本文从审计委员会的存在性、独立性和勤勉程度三个方面,将审计委员会与审计师规模、异常审计收费、审计师变更等结合起来考虑,探讨审计委员会治理对上市公司年报审计意见类型以及不利审计意见改善和审计意见恶化的影响。研究表明,相对于审计委员会的存在性,审计委员会的独立性和勤勉程度对外部独立审计师审计判断及其所出具的审计意见的影响更为显著;在结合考虑审计师规模、审计收费、审计师变更等相关因素的前后均可以发现,在董事会中设立审计委员会并切实提高审计委员会的独立性和勤勉程度,不仅有助于提升上市公司财务报告的质量,而且亦有助于在一定程度上对管理层的审计意见购买行为进行有效的制衡。     

审计收费、审计师变更与意见购买

实证研究表明,虽然变更审计师增加了上市公司年报被出具非标准审计意见和审计意见恶化的可能性,但是审计师变更更为显著地提高了审计意见改善的可能性;审计收费异常增加与被出具非标准审计意见和审计意见恶化的可能性负相关.公司管理层在一定程度上可以成功实现审计意见购买的动机.此外,异常审计收费、审计收费异常增加和异常降低与审计师变更之间不存在显著的交互效应.     

盈余管理 审计师变更与审计师独立性

盈余管理与审计师变更存在一定的相关性。本文检验了审计师变更公司在新任审计师的第一年、前任审计师最后一年、倒数第二年的可操控性应计利润及其在不同年份之间的变化。检验结果表明 ,虽然前任审计师在其最后一年聘期内采取了比其他审计师更为稳健的会计处理方法 ,以致被公司变更 ;但新任审计师在第一年并未完全配合公司。这在一定程度上表明 ,公司变更审计师并未达到预期的目的 ;前任审计师、后任审计师的独立性均很强。这可能要归功于事务所脱钩改制 ,以及有关部门有效的监管措施     

审计师变更的经济后果研究——来自中国证券市场的经验证据

本文运用2002—2008年我国上市公司数据研究了审计师变更的经济后果。以公司市场价值与其财务盈利的相关系数(简称为盈利可信度)作为审计师变更的经济后果的替代变量,通过研究我们发现:审计师变更总体上降低了上市公司的盈利可信度;变更前一年度财务报告被出具非标准审计意见或者处于财务困境的公司,发生审计师变更使其盈利可信度下降的程度更大;出于对审计服务级差需求的审计师变更,无论是升级变更还是降级变更公司的盈利可信度均显著高于同级变更的公司,而升级变更为声誉较好的国际四大会计师事务所带来的盈利可信度的提高程度最大;审计委员会的设立与否以及上市公司的盈余管理程度对于审计师变更的经济后果没有显著影响,这可能是由于我国上市公司审计委员会的独立性不强以及投资者对上市公司的盈余管理行为识别不足造成的。研究结论同时还说明审计意见分歧、上市公司财务困境以及对审计服务的级差需求是我国上市公司变更审计师的主要原因。本文的研究发现有助于包括上市公司、会计师事务所、投资者以及证券市场监管部门在内的信息使用者更好地理解和评价我国证券市场中的审计师变更现象,并为相关领域的研究提供了新的经验证据。     

企业集团审计师变更与审计意见购买

审计意见购买是学术界和监管部门都十分关注的话题,但以往研究多以单个上市公司为对象来研究审计师变更和审计意见购买,且国内外的经验研究一直未得到一致的结论。考虑到在新兴市场国家,企业集团是主要的企业组织形式,本文以企业集团作为一个整体进行研究,发现审计师对集团内任何一家上市公司出具非标准审计意见,可能导致集团内多家上市公司变更该事务所的审计业务;企业集团通过变更事务所能够实现审计意见改善。此外,变更对象不同,变更后果也不同,首次审计该集团业务的审计师更容易屈服于集团,更容易被收买。     

The Simultaneous Relation Between Auditor Switching and Audit Opinion: An Empirical Analysis

Previous studies examining the relation between the audit opinion and auditor switching assume a one-way causation, with the issuance of a qualified opinion triggering a switch. However, analytical studies dealing with auditor independence issues (e.g., Magee and Tseng, 1990; Dye, 1991; Teoh, 1992) suggest an opposite causation, in which the auditor is less likely to qualify the opinion for a client who may switch auditors. Some evidence of an opposite causation is provided by Krishnan (1994), who finds that auditors treat switchers more conservatively (relative to non-switchers) in issuing the audit opinion. The causation between switching and the audit opinion is clearly important for policy decisions regarding both opinion shopping and auditor independence. In this paper, we test the two-way causation hypothesis and find evidence in support of a two-way causation. Our simultaneity-adjusted estimates confirm previous findings of a positive effect of a qualified opinion on switching (Chow and Rice, 1982; Craswell, 1988; Citron and Taffler, 1992). However, we find in addition that auditors are more likely to issue qualified opinions to switchers. This finding does not support the analytical studies cited earlier.     

The effect of mandatory auditor assignment and non-audit service on audit fees: Evidence from Korea

In Korea, regulators could assign auditors to firms. We investigate the relationship among audit fees, mandatory auditor assignment, and the joint provision of non-audit and auditor services in Korea. We find that assigned auditors charge significantly higher audit fees than freely selected auditors. We also find that the joint provision of non-audit and audit services does intensify the relation between auditor assignment and audit fees. Combined with the results of other studies that have shown that firms audited by assigned auditors report smaller amounts of discretionary accruals than firms audited by freely selected auditors, our results suggest the possibility that mandatory auditor assignment may improve auditor independence.     

The determinants of auditor switching from the perspective of corporate governance in China

This paper reports the association between firms' internal corporate governance mechanisms and their auditor switch decisions in the Chinese context. We identify two types of auditor switch, namely switching to a larger auditor and switching to a smaller auditor. Three variables are used to proxy for firms' internal corporate governance mechanism, including the ownership concentration (shareholding by the largest owner), the effectiveness of supervisory board (SB), and the duality of chairman of board of directors (CBoD) and CEO. We regressed the internal corporate governance variables over firms' audit switching types during a specific period of 2001-2004 when a bear market continued in China. The empirical results demonstrate that firms with larger controlling owners or in which CBoD and CEO are held by the same person are more likely to switch to a smaller auditor rather than to a larger one. However, the effect of the SB variable does not have a significant impact on auditor switching decisions. In general, the study findings suggest that firms with weak internal corporate governance mechanism tend to switch to smaller or more pliable auditors in order to sustain the opaqueness gains derived from weak corporate governance. On the other hand, with the improvement of corporate government, firms should be more likely to choose large (high-quality) auditors in making auditor switching decisions.     

New Auditors’ Decisions for Released Firms from the Mandatory Auditor Designation Rule: Evidence From South Korea

This study examines the effect of the mandatory designation rule on audit fees charged and audit hours rendered by auditors for firms released from the mandatory auditor designation rule in the Korean audit market. Under the mandatory auditor designation rule, which took effect in 1991, problematic firms are assigned new auditors by the Financial Supervisory Service. Previous studies suggest that this regulation positively affects the quality of audits by promoting auditor independence. Thus, this study hypothesises that firms that have been subjected to mandatory auditor designation improve the quality of their financial reporting, and that auditors hired after the mandatory designation period account for reduced audit risks when determining audit fees and audit hours. This study shows that audit fees and audit hours of firms released from the mandatory auditor designation rule are lower than those of other initial audit engagements. Taken together, this study's findings reinforce the notion that auditors’ perceptions of changes in audit risk yield corresponding changes in the audit fees they charge and audit hours they render.     

Costs Associated With Going-Concern-Modified Audit Opinions: An Analysis of the Australian Audit Market

This article examines the potential costs to Australian auditors and their clients from the issuance of first-time going-concern-modified audit opinions. We examine the population of Australian companies receiving a first-time going-concern-modified audit opinion during the period 1994–97 and a matched sample of financially distressed firms receiving a clean audit opinion. Results indicate that auditor switching is positively associated with receipt of a going-concern-modified opinion. However, we find no empirical evidence that there is a self-fulfilling prophecy of increased probability of company failure following the issuance of a going-concern-modified opinion for the Australian companies in our study. Our analyses of lost audit fees indicate that auditors issuing first-time going-concern-modified audit opinions lost proportionately more fees by losing clients (through switching or company failure) than firms not issuing a going-concern-modified opinion to financially stressed clients.     

The impact of revolving door practice and policy on nonprofessional investors’ perceptions of auditor independence

This study investigates whether an ex-auditor’s employment with an audit client impairs nonprofessional investors’ perceptions of auditor independence, and whether the strength of the US revolving door policy improves their perceptions of auditor independence. Despite nonprofessional investors owning over one-third of the US equity holdings, the literature has not examined how revolving door policy impacts their perceptions of auditor independence. Two between-subjects experiments examine these issues. The first experiment finds that investors perceive the ex-auditor’s integrity to be significant in explaining the firm’s decision to manage earnings, irrespective of the firm’s previous working relationship with the ex-auditor. The results from experiment two indicate that strengthening the revolving door policy above that of the American Institute of Certified Public Accountants’ policy does not improve perceptions of auditor independence. Academics may be interested in triangulating the independence ‘in appearance’ results of this study to the independence ‘in fact’ results of other studies, since the Securities and Exchange Commission asserts that both facets of independence are equally important. The results may also be of interest to academics and practitioners, as prior research suggests that restricting auditors’ moves to management positions with the client impairs firms’ abilities to hire quality auditors.     

Regulatory risk and auditors’ reporting conservatism: Evidence from Chinese comment letters

We study how auditors respond to regulatory risk that arises when their clients receive comment letters from Chinese stock exchanges. Our results show that auditors are more likely to issue modified or conservative—but not excessively conservative—audit opinions to the recipients of comment letters. This reporting conservatism is especially pronounced when the regulatory risk perceived by auditors rises, such as when comment letters contain more questions, when more comment letters are issued, when the auditors must give opinions on specific issues, or when comment letters involve more auditor issues. Comment letters have been issued in China since 2013, but did not have to be disclosed until 2015. We find no significant difference in the impact of comment letters on auditor conservatism between pre- and post-disclosure periods. Further, the size of auditor firms has no significant effect on the impact of comment letters in post-disclosure periods. We interpret our results as supporting the regulation risk hypothesis.     

Does auditor tenure affect accounting conservatism? Further evidence

Accounting regulators are concerned about the potential threat of long-term auditor–client relationships on auditor independence, leading to lower audit quality. Jenkins and Velury (2008, hereafter JV) document a positive association between the conservatism in reported earnings and the length of the auditor–client relationship. A primary objective of this study is to extend JV by providing evidence that the relationship between conservatism and auditor tenure is not unique for all firms. In particular, this study finds that the positive association only exists for large firms or firms strongly monitored by their auditors, while for smaller firms or firms weakly monitored by their auditors, I observe a significantly negative association between auditor tenure and conservatism.     

Client influence and auditor independence revisited: Evidence from auditor resignations

Financial scandals such as the Enron-Andersen debacle provoke concerns that auditors lack independence when faced with influential clients. Unlike previous studies that examine whether client influence affects audit quality on ongoing engagements (providing mixed results), we investigate whether client influence (which engenders “independence risk”) at the audit-office level affects auditor resignations from high engagement-risk clients. We construct summary measures of engagement risk, using client disclosures on Form 8-K filings, potential risk factors (e.g., litigation risk), and auditor action (e.g., issuance of a going concern opinion) on the previous year’s financial statements. Focusing on risky clients, we find that auditors are more likely on average to resign from influential clients, and this positive association holds for auditors that are less likely to have mechanisms in place to mitigate independence risk. Also, importantly, influential clients are prevalent across the spectrum of client size, and the positive association between client influence and auditor resignations holds for both large and small clients.     

Audit fee lowballing: Determinants,recovery, and future audit quality

Prior research on the link between lowballing (LB) of audit fees and audit quality is inconclusive. Using more recent data and an innovative design, we define LB engagements as those where the audit fee discount is at least 30 percent. We consider three research questions to understand the possible link between LB and audit quality. First, we investigate whether the two variables that are often associated with auditor independence in the literature—non-audit fees and client importance—are related to LB. Second, we test whether lowballing auditors recoup initial audit fee discounts in the future period. Lastly, we investigate the relation between recovery of audit fees and future audit quality. We find that non-audit fees in the first year of engagement are negatively related to the propensity to LB. LB is significantly positively related to client importance for client firms switching from a non-Big N to another non-Big N auditor while the relation is insignificant for client firms switching from a Big N to another Big N auditor. The results of non-audit fees and client importance indicate that economic dependence does not motivate audit firms to lowball. Further, lowballing auditors tend to recoup their initial fee discounts in subsequent periods via increases in audit fees. Using multiple measures of audit quality, we do not find a significant relation between recovery of audit fees and future audit quality. Overall, contrary to regulators’ concerns, our results suggest that LB does not impair audit quality.
