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。     

非标准审计意见足以保护审计师吗?——基于证券执法的证据

本文以2001—2012年93家因虚假陈述被证监会惩戒的公司和39家审计师被同时惩戒的公司为研究样本,采用Bivariate probit和两阶段最小二乘法模型对审计意见和审计师惩戒之间的关系进行了验证。研究结果表明,我国审计师出具非标意见反而越易受到惩戒,且惩戒程度也越高的悖论,这与我们的预期不符。而进一步研究发现,这是由于审计意见变通所导致。监管部门有效发现了审计意见变通行为,因此审计师仅出具非标意见不足以保护自身,只有有效披露公司的重大错报,出具正确恰当的审计意见才可以远离惩戒。本文的研究对于正确认识审计师惩戒有着重要的启示,同时为监管机构出台更加有效的审计监管政策提供一定的借鉴。     

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。     

上市公司违规处罚与审计师更换——基于“一会两所”处罚案例的分析

本文以2002-2009年被中国证券监督委员会及上海和深圳证券交易所处罚且违规行为与审计师相关的上市公司为样本,研究上市公司被处罚后审计师更换的选择行为以及更换审计师对避免再次处罚的效果。结果表明,相对于未受处罚的公司,被处罚公司更倾向于更换审计师;相对于上一年被出具非标审计意见的被处罚公司,上一年被出具标准审计意见的被处罚公司更倾向于更换审计师;上一年被出具标准审计意见的被处罚公司,更换审计师的行为能够有效抑制再次被处罚事件的发生。     

制度环境、审计供求与审计治理——基于我国证券市场中审计师变更问题的实证分析

本文基于我国证券市场中审计师变更问题这一动态视角考察了制度环境对外部审计治理的影响。通过研究,我们发现:首先,在制度环境发展相对落后的地区,上市公司频繁更换审计师的现象更严重;其次,在制度环境发展相对较好的地区,上市公司更可能发生审计师升级变更,表明其对高质量审计服务的需求;第三,在制度环境发展较差的地区,由于诉讼风险和诉讼成本较低,继任审计师为了获得审计客户更容易发生变通审计意见的行为,说明审计师难以发挥其外部治理的功能进而弥补制度环境的缺陷。本文的研究发现说明制度环境同时影响审计需求和审计供给两方面的行为表现,并支持了制度环境与外部审计治理是相互促进的关系。     

客户相对规模、非诉讼成本与审计意见决策

通过对2004年沪深两市上市公司的研究,我们发现,相对较小的客户(相对于其审计师事务所的其他客户)被出具非标准审计意见的概率较高。审计师事务所对小客户出具非标准审计意见的倾向性,可能与诉讼成本和非诉讼成本的权衡有关。给定会计准则的偏离事项,审计师对大客户出具审计意见,预期的非诉讼成本(如果出具非标准审计意见)可能高于预期的诉讼成本(如果出具标准无保留意见),因此理性的审计师倾向于出具标准无保留意见;审计师对小客户出具审计意见,预期的非诉讼成本(如果出具非标准审计意见)可能低于预期的诉讼成本(如果出具标准无保留意见),因此理性的审计师倾向于出具非标准审计意见。诉讼成本和非诉讼成本的权衡,导致相对较小的客户更容易招致审计师的不利审计意见。     

非标准审计意见可以减轻审计师的处罚吗?——基于2001～2015年证监会的处罚公告

本文手工搜集中国证监会的处罚公告,以2001~2015年间因虚假陈述被中国证监会处罚的176家上市公司和49家同时被处罚的事务所和审计师为样本。通过统计分析的方法研究审计意见类型与审计师被处罚,以及处罚程度的关系。研究结果显示,非标准审计意见类型并不能避免审计师被处罚但是非标准审计意见类型可以减轻审计师以及事务所被处罚的程度。     

审计师选择与设立审计委员会的自选择问题——来自中国证券市场的经验证据

本文采用Heckman(1978)的二阶段回归方法,以2002-2006年我国证券市场上市公司为研究样本,在研究审计师选择的同时控制了设立审计委员会的自选择问题,并将公司设立审计委员会的实际情况与假设的相反情况进行对比,分析它们不同的审计师选择倾向,从而间接检验了审计委员会的治理效率。研究发现:自选择问题对审计师选择存在显著的影响。因此,拒绝了公司随机设立审计委员会的原假设;在控制自选择之后,回归方程中变量的斜率系数整体上存在显著差异;并且没有设立审计委员会的公司比设立审计委员会的公司更可能聘请四大会计师事务所。     

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.     

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。     

Audit firm, corporate governance, and audit quality: Evidence from Bahrain

The aim of this research is to document the perceptions of credit and financial analysts with regard to the relationship between the effectiveness of audit committee, size of the auditing firm and audit quality in the context of Bahrain, which is characterized by a developed financial sector, low-liquidity stock market, low turnover in board of directors of listed firms, an inactive merger and acquisitions market and almost non-extent litigation. A survey of 300 credit and financial analysts shows that analysts considered auditors' opinion useful. Both credit and financial analysts see the credibility of financial statements to be a function of the size of the auditing firm. Both groups assume that the characteristics of Big-Four firms allow them to produce better-quality reports than non-Big firms. Non-audit services were found to affect auditor's independence and hence impair audit quality. Both the groups of analysts believe that effective audit committee enhances the quality of audit reports. Financial analysts perceive financial statements to be more credible than do credit analysts.     

Audit pricing, quality of earnings and board independence: The case of the Athens stock exchange

Prior research has pointed to the importance of the determinants of audit pricing. This paper examines empirically the effect of both audit independence and earnings management on the audit pricing by companies listed on the Athens Stock Exchange. This test is performed in an institutional setting with excessive earnings management and poor corporate governance mechanisms. The results based on a sample of 97 Greek companies for a five-year period (2000-2004), show that there is a positive association between audit independence and auditing pricing. Our results also indicate a positive association between audit pricing and earnings management for the small size companies. Taken together our results suggest that strong governance is related to increased needs for quality assurance services and that the relation between earnings management and audit pricing might indicate potential red flags. Finally, limitations, suggestions for further research and policy implications for regulatory agencies are offered.     

Are fully independent audit committees really necessary?

Accounting scandals and concerns about the quality of financial statements have led to many calls for improved audit committee effectiveness. Prior research indicates that audit committee independence is positively related to effective oversight of the financial reporting process. Unfortunately, prior research has not provided an answer as to how much independence on the audit committee is enough. This is an important unanswered question because while Section 301 of the Sarbanes-Oxley Act of 2002 (SOX) currently requires all listed companies to maintain an audit committee that is 100% independent there has been much debate regarding easing the SOX requirements for smaller and foreign companies. In this paper we examine whether the regulatory requirements of a completely independent audit committee are necessary to obtain the monitoring benefits related to audit committee independence that have been documented in prior literature. Our results suggest that the benefits of audit committee independence are consistently achieved only when the audit committee is completely independent. These results provide support for the SOX requirement of 100% independent audit committees.     

审计委员会制度与中国上市公司治理创新

本文研究中国上市公司现行治理结构中的企业会计事务控制权安排及其缺陷,并提出改进措施。我们研究发现,在中国上市公司现行治理结构中,企业经理人不仅拥有企业内部会计事务的积极权力,而且实质拥有企业外部会计事务的积极权力,其中的作为董事会下设专门委员会的审计委员会不是我们所设计的本原性质的审计委员会,而是接近于美国现行公司治理结构中的审计委员会。这一安排不符合关于现代企业会计事务控制权安排的分权制衡原则,难以保证注册会计师审计的独立性。我们在分析中国上市公司治理中的监事会监督为什么会流于形式的基础上,提出应进行中国上市公司治理的创新,即取消监事会(制度),设立独立于董事会与之平行的符合本原性质的审计委员会,或将监事会改造为符合我们界定的本原性质的审计委员会。     

审计委员会与审计质量——来自中国A股市场的经验证据

本文以中国2004年—2005年期间获得无保留审计意见的A股上市公司为研究样本,采用截面Jones模型估计出的公司操纵性应计利润(盈余管理)的绝对值作为审计质量的衡量指标,考察了审计委员会与审计质量之间的关系。研究发现,在控制了"会计师事务所规模"、"公司是否面临退市风险"、"审计意见是否带强调事项"、"公司经营活动现金流"、"公司盈余数量"、"年度"等指标后,设立审计委员会的公司的盈余管理绝对值显著比未设立审计委员会的公司小,这说明审计委员会能够显著的提高审计质量。进一步研究发现:审计委员会的成立时间越长,审计质量越高;审计委员会在2005年的作用比2004年更加显著。     

Audit Committee Members: What Goes on Behind Closed Doors?

Using a qualitative research paradigm, this study examines audit committee effectiveness from the perspective of audit committee members of New Zealand listed companies. The findings reveal that audit committee members perform a range of overlapping tasks and justify their existence in their audit committees by fulfilling the ‘expectations’ that are placed on them. Many quantitative research studies have examined the association between different dimensions of audit committee inputs and financial reporting outputs. The empirical evidence, however, is mixed and remains far from conclusive (Bédard and Gendron 2010). One of the primary reasons for the inconsistent findings is the lack of understanding of the actual process by which audit committees perform their responsibilities. Using a qualitative research paradigm, this study examines audit committee activities, processes and effectiveness from the perspective of audit committee members of New Zealand listed companies. The study argues that performing audit committee duties is an intended process, whereby audit committee members justify their actions and the effectiveness of their audit committees. The paper contributes to the limited literature on how audit committees operate and, by doing so, provides possible explanations for the inconsistent findings of the quantitative audit committee research. In particular, the paper invites further discussion on whether audit committee members can be (or should be assumed to be) independent when discharging their role of overseeing auditing and financial reporting‐related matters.     

审计委员会特征与会计师事务所变更的经验研究

本文以会计师事务所变更为视角,探讨具备怎样特征的审计委员会才能有效履行其职责。研究表明:审计委员会的独立性和专业性与会计师事务所变更显著负相关;审计委员会的开会次数与会计师事务所变更没有显著关系,说明审计委员会的存在有助于减少会计师事务所变更。但在对会计师事务所变更的进一步研究中,我们并没有发现会计师事务所变是为了追求更高审计质量的进一步证据,也说明审计委员会对会计师事务所变更的影响仍然有限。这些研究结论为完善我国审计委员会制度提供了经验证据。     

The existence and independence of audit committees in France

This paper uses an agency theory framework to investigate the determinants of audit committees in France. Empirical tests address a cross-sectional sample of 285 listed companies for the fiscal year 1997, which is two years after the first Viénot report recommending the creation of audit committees among listed companies. Multivariate analyses show that the existence of an audit committee, and the committee's independence, are both negatively correlated with insider ownership, consistent with the owner-manager agency theory that considers audit committees as devices aimed at strengthening the monitoring system, the quality of financial reporting and the whole corporate governance environment. The existence of an audit committee that complies with corporate governance recommendations (i.e., a minimum of three directors, all of whom are non-executive directors) also positively depends on leverage if the firm has a high-IOS (Investment Opportunity Set). The quality of accounting numbers thus seems important in shareholder-debtholder relationships if lenders are potentially more exposed to default risk and expropriation mechanisms. However, this result might be sensitive to the IOS measurement and classification of high- and low-IOS companies. Finally, the presence of an audit committee is found to be positively correlated with board size, firm size, auditor reputation, and with the diversity of the company's operations.     

The Role of Risk Management and Governance in Determining Audit Demand

Abstract:  Most prior research into audit fees has been based on a theoretical model which treats audit fees as the by-product of a production function ignoring potential demand forces that may drive the level of the audit fee. Inspired by prior 'anomalous' results, we take a different perspective by focusing on demand factors that may affect the level of the audit fee. Using data collected from a sample of listed companies in Belgium, we consider both disclosures about risk and risk management and actual decisions about corporate governance to examine whether audit fees are higher when these demand forces exist. In general, we expect that external auditing will increase in situations where there are multiple stakeholders with individual risk profiles who can shift some of the cost of monitoring to other stakeholders. Consistent with our theory and expectations, our results indicate that audit fees are higher when a company has an audit committee, discloses a relatively high level of financial risk management, and has a larger proportion of independent Board Members. Audit fees are lower when a company discloses a relatively high level of compliance risk management. The latter result indicates that controls are only complementary as long as they are voluntary, as mandated controls act as substitutes for non-mandated controls.     

上市公司内部审计外包决策的影响因素研究

本文在分析我国上市公司内部审计外包情况的基础上,建立了基于交易成本理论和公司治理理论的外包程度影响因素模型,并利用我国上市公司数据予以实证分析。结果发现,内审资产的专用性、内审活动的开展频率、审计委员会的有效性是影响内部审计外包程度的主要因素,即内审资产的专用性越低,内审活动开展越不频繁,审计委员会未成立或未有效运作,公司越可能进行内部审计外包。
