审计委员会治理与审计意见   总被引:4,自引:0,他引:4  
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。  相似文献

机构持股、审计师选择与审计意见   总被引:1,自引:0,他引:1  
本文运用中国A股上市公司的数据,研究了机构投资者持股对上市公司的审计师选择及审计意见的影响。研究结果发现,机构投资者持股比例越高,公司越可能聘请大型会计师事务所进行审计,也更容易获得清洁的审计意见。机构投资者对审计师选择、审计意见的上述影响在法律保护较差的环境中更加明显。在控制了自选择问题后,上述结论仍然成立。本文的研究结论表明,我国的机构投资者能够改善独立审计的治理环境,进而提升公司的治理水平,它是法制等外部治理环境的重要替代性治理机制。  相似文献

高质量审计能够降低信息不对称、约束管理层的机会主义行为,而权益融资和债务融资对信息不对称的敏感性是不同的,这两类资财提供者对外部审计的依赖程度也不同,因此,审计质量可能会对公司融资方式的选择产生影响。本文利用我国2008-2012年沪深两市A股上市公司及其审计师数据,分别以行业专长和事务所规模作为审计师质量的替代变量,并用控制函数方法解决审计师的自选择问题,考察了审计师质量对上市公司融资方式选择的影响。结果发现,选择高质量审计师的公司,更倾向于进行权益融资。进一步研究发现,在信息不对称问题更为严重的小规模公司中,审计师质量对权益融资的促进作用更为明显。  相似文献

本文在理论上深入分析审计制度安排中独立性威胁现象及审计委员会制度对独立性威胁的制约作用之后,基于2002—2004年我国上市公司审计委员会设立的基本情况,以审计意见和事务所变更为反应变量,对审计委员会制约独立性威胁的有效性进行了实证研究。研究发现,设立审计委员会的公司更不易被出具非标准审计意见,说明审计委员会的设立并不能有效提高审计师的独立性,但这同时也是反映政策效应的结果,即规模较大的上市公司倾向于主动配合监管政策设立审计委员会。本文的研究还发现,审计委员会的设立并不能令审计师免于因出具令上市公司不满的审计意见而被改聘的结果,说明我国的审计委员会制度未能在制约独立性威胁方面发挥作用,该结论同时得到实践调查结果与补充检验的支持。据此,本文认为,我国审计委员会制度在制约独立性威胁方面的功能还有待于进一步落实。  相似文献

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。  相似文献

本文结合公司的信息不对称程度,从审计收费与审计质量的角度来研究本地审计师的合谋效应问题。研究结果表明,异常审计收费降低了本地审计师对信息不对称程度高的盈余管理公司出具非标审计意见的概率,而并不会降低本地审计师对信息不对称程度低的盈余管理公司出具非标审计意见的概率,同时,异常审计收费也不影响外地审计师出具非标审计意见的概率,表明本地审计师与信息不对称程度高的盈余管理公司之间存在合谋行为;进一步研究表明,信息不对称程度高的盈余管理公司更可能选择本地审计师进行审计,从而为本地审计师的合谋效应提供了进一步的证据。  相似文献

审计委员会与审计质量——来自中国A股市场的经验证据   总被引:12,自引:0,他引:12  
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。  相似文献

审计委员会作为公司治理结构中的重要组成部分,其在公司治理中的作用越来越受到重视。中国上市公司很多都是国有企业或者由国有企业改制而来,终极控制人是国家控制的公司占有相当大的比例。这种所有制的特殊性是否会对审计委员会以及公司治理产生一定影响?针对这一问题,本文从中国上市公司终极控制人类型的角度入手,通过研究国家控制与民营企业控制的公司、政府直接控制与间接控制的公司以及中央政府控制与地方政府控制的公司之间有无显著差异来研究审计委员会的设立动机。研究结果表明:同民企控股上市公司相比,国家控股上市公司建立审计委员会的动机更强。政府通过实业公司间接控制的公司比政府直接控制的公司设立审计委员会的动机更强。相对于中央政府,地方政府通过设立审计委员会来加强监督的动机更强。  相似文献

以2002~2012年我国1337家 A 股 IPO 公司为样本,实证检验了审计师选择与 IPO 公司盈余稳健性的关系。研究发现:国际四大审计的 IPO 公司的营业利润、利润总额、净利润和综合收益的稳健性均显著低于非四大审计的 IPO 公司的盈余稳健性,但本土十大与非十大审计的 IPO 公司之间的盈余稳健性不存在显著差异。  相似文献

上市公司董事会特征与审计费用率   总被引:3,自引:0,他引:3  
本文以披露了2003年年报审计费用的上市公司为样本,借助回归分析方法,研究了审计费用率与董事会特征的相关性。本文发现,审计费用率与独立董事的规模显著负相关,与董事会的独立性、非独立董事规模显著正相关,与董事会会议次数不相关;与审计委员会的设立、独立董事的薪酬相关性不显著。客户规模、子公司个数、应收账款和存货在总资产中的比重、审计任期仍是影响审计费用率的主要因素;审计任期与审计费用率的相关性说明,审计师首次执行审计业务时不仅没有审计折价现象,反而可能存在显著的审计溢价。发现表明,独立董事相对规模较大的董事会支持高质量的审计服务,而绝对规模较大的董事会更可能改善公司内部控制环境。  相似文献

An important issue in the regulation of corporate behavior is its impact on the monitoring configuration selected by top management. In this article, we provide evidence consistent with the notion that the recent trend toward audit committee formation, and the movement toward Big-Eight auditors, are responses to increased legal exposure of the board of directors, notably stemming from the passage of the Foreign Corrupt Practices Act of 1977. The costs associated with changes in monitoring configurations are also considered. In particular, it is argued that auditor assistance can substantially reduce the cost of audit committee formation. Because external auditors may have differential incentives to support audit committee formation, a hypothesis linking auditor identity and audit committee formation is offered. Recent auditor changes and audit committee formations of American Stock Exchange companies are examined to provide positive evidence for the theory. The data reveal a clear trend to form audit committees, and a movement to Big-Eight auditors. Underscoring the importance of auditor involvement, it is shown that audit committees were more likely to be formed given recent selection of a new Big-Eight auditor.  相似文献

基于中国证券市场在2007年年度报告中首次公开披露的审计委员会履职信息,本文考察了审计委员会与注册会计师的沟通过程、方式和内容,初步探究了审计委员会发挥公司治理功效的可能机制。我们发现:审计委员会投入的审阅时间普遍很少;审计委员会与注册会计师的沟通方式普遍单一,且以函件方式为主,沟通内容以程序化内容为主,具体内容或实质性内容的沟通较少;公司披露的审计委员会与注册会计师的沟通方式和内容信息的可靠性值得商榷;用以反映审计委员会宏观特征的变量(诸如规模、独立性、会计与财务专长)是否能有效反映审计委员会的治理职能,值得商榷。  相似文献

We investigate whether the characteristics of audit committee (AC) chairs are associated with decisions about auditor choice, audit fees and audit quality. Using hand-collected Australian data, firms with AC chairs who have longer tenure and multiple AC memberships across several boards are found to be more likely to choose Big 4 and/or industry specialist auditors, pay higher audit fees and have lower discretionary accruals. Those AC chairs with higher business qualifications are more likely to hire a Big 4 auditor, pay higher audit fees and have lower discretionary accruals, while AC chairs with professional qualifications are more likely to hire a Big 4 and/or industry specialist auditor. In contrast, firms with AC chairs who are executive directors are less likely to hire a Big 4 auditor and have higher discretionary accruals. Our findings contribute to the literature by documenting that various characteristics of AC chairs are important for enhancement of auditor selection and audit quality.  相似文献

Studies focusing on governance mechanisms argue that auditor monitoring is one of several governance mechanisms that exist in the firm, and these mechanisms supplement each other. Extending this argument, I examine whether firms support auditor monitoring with audit committee monitoring when auditor oversight is deemed to be weak. Prior auditing literature argues that audit quality is affected by auditors' lack of familiarity with their clients' activities. Since lack of auditor–client familiarity exists in the first year of auditor–client tenure, I examine whether firms increase their audit committee monitoring during the year of auditor change. For a sample of firms that changed auditors between 2006 and 2012, the findings show that audit committees meet more frequently in the first year of audit engagement. Further tests show that firms' past reporting behavior play a significant role in the demand for more audit committee meetings and the increase in the audit committee meetings in the initial year of auditor engagement positively affects reporting quality.  相似文献

Using unique data on audit hours from China, this paper investigates the effort-saving effect of the audit committee–auditor interlocking (AClk). We find that AClk is negatively associated with audit effort without any deterioration in audit quality. The results suggest that AClk has an effort-saving effect through information sharing between interlocked audit committee members and auditors. However, auditors retain the effort-saving benefits of AClk without sharing them with their client firms. Further analysis shows that the effort-saving effect of AClk is more pronounced for client firms whose auditors have industry expertise, for client firms that share the same individual auditor, or for client firms that share audit committee members with financial expertise.  相似文献

We examine the impact of audit firm versus partner rotation on non-professional investors’ independence-related perceptions, extending prior research on auditor rotation and independence in fact. Arguments for mandatory audit firm rotation continue to be made by regulators and investor groups based, in part, on the idea that firm rotation will incrementally strengthen independence in appearance relative to audit partner rotation. We report the results of two experiments. The first examines 5-year audit firm versus partner rotation under relatively weak or strong audit committees. We find no statistically significant difference in beliefs about how much of an income reducing audit difference management will record, or in beliefs about auditor independence, between the two auditor rotation conditions. On the other hand, we find that non-professional investors do believe more of the audit difference will be recorded, and the auditors will be more independent, under a strong audit committee than a relatively weak audit committee. The second experiment provides further evidence on audit firm versus partner rotation by examining a setting involving a 26-year audit firm–client relationship. Again, no statistically significant differences between the two auditor rotation conditions were found. These findings suggest that compared to audit partner rotation, audit firm rotation does not strengthen independence in appearance among non-professional investors and that non-professional investors recognize the value of strong audit committees.  相似文献

This paper offers an explanation for audit committee failures within a corporate governance context. The management of a firm sets up financial statements that are possibly biased. These statements are audited/reviewed by an external auditor and by an audit committee. Both agents report the result of their work, the auditor acting first. Both use an imperfect technology that results in a privately observed signal regarding the quality of financial statements. The audit committee as well as the auditor are anxious to build up reputation in the labor market. Given this predominant goal they report on the signal in order to maximize the market’s assessment of their ability. At the end of the game the true character of the financial statements is revealed to the public with some positive probability. The market uses this information along with the agents’ reports to update beliefs about the agents’ abilities. We show that a herding equilibrium exists in which the audit committee “herds” and follows the auditor’s judgement no matter what its own insights suggest. This result holds even if the audit committee members are held liable for detected failure. However, performance based bonus payments induce truthful reporting at least in some cases.  相似文献

A prime objective of the SOX is to safeguard auditor independence. We investigate the relation between audit committee quality, corporate governance, and audit committees' decision to switch from permissible auditor-provided tax services. We find that firms with more independent boards, audit committees with greater accounting financial expertise, higher stock ownership by directors and institutions, that separate the CEO and Chairman of the board positions, and with higher tax to audit fee ratios are more likely to switch to a non-auditor provider. Further, we document that firms are more likely to switch prior to issuing equity. We find no evidence that broad financial expertise on audit committees is related to the switch decision, suggesting that the SEC's initial narrow definition of expertise is more consistent with the objective of the SOX. Overall, our results suggest that accounting financial expertise and strong corporate governance contribute to enhanced audit committee monitoring of auditor independence.  相似文献

In this paper we investigate the relation between audit committee quality, auditor independence, and the disclosure of internal control weaknesses after the enactment of the Sarbanes-Oxley Act. We begin with a sample of firms with internal control weaknesses and, based on industry, size, and performance, match these firms to a sample of control firms without internal control weaknesses. Our conditional logit analyses indicate that a relation exists between audit committee quality, auditor independence, and internal control weaknesses. Firms are more likely to be identified with an internal control weakness, if their audit committees have less financial expertise or, more specifically, have less accounting financial expertise and non-accounting financial expertise. They are also more likely to be identified with an internal control weakness, if their auditors are more independent. In addition, firms with recent auditor changes are more likely to have internal control weaknesses.  相似文献
