资源控制权与审计师轮换的治理效应

审计师轮换是构建独立审计秩序化格局以防范会计舞弊的重要监管手段。本文基于会计师事务所内部治理尤其是资源整合的角度研究了审计师轮换对审计质量的影响,结果发现,审计师轮换后,会计师事务所出具非标意见的概率显著上升,高客户资源控制权个人化会计师事务所显著抑制了公司的正向盈余管理水平;高客户资源控制权个人化会计师事务所在审计师轮换后抑制公司正向盈余管理水平的提高幅度大于低客户资源控制权个人化会计师事务所。结果表明,审计师轮换提高了审计独立性和审计质量,有助于实现客户资源控制权个人化向会计师事务所化的转变。     

本地审计师的合谋效应

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。     

环境不确定性与审计意见:基于股权结构的考察

本文从公司股权结构的角度,研究企业环境不确定性与审计意见之间的关系。发现环境不确定性所带来的风险,促使审计师出具更多的非标审计意见以降低可能的损失赔偿;由于政府的支持,环境不确定性对国有企业的影响较小,审计师因而对国有企业环境不确定性出具非标审计意见的概率相对要低;进一步的研究发现,审计师对环境不确定性增加了收费,然而,国有控股公司因环境不确定性而增加的审计收费幅度相对较低。     

财务报表重述公司审计质量研究

以财务报表重述公司为研究对象,考察财务报表重述公司年报审计质量。结果表明:财务报表重述的幅度对非标审计意见的出具有显著的影响力;初始差错年和报表重述年,注册会计师都能在一定程度上识别上市公司的盈余管理动机,并在审计意见中有所反映;审计师任期和对财务报表重述公司出具非标审计意见之间没有显著的相关性;事务所规模和非标审计意见的相关性并不显著,结论没有支持大事务所更有可能对重述公司出具非标审计意见。     

事务所变更、审计意见类型与财务重述

本文以2005-2009年间中国A股上市公司补充与更正报告中出现"会计差错更正"项目的公司为研究对象,分别以是否发生财务重述和重述调整方向为因变量,系统研究了事务所变更、审计意见类型对财务重述的影响。形成的结论主要有:被出具标准审计意见的公司,发生财务重述以及负向财务重述的概率均低于被出具非标审计意见的公司;没有发现事务所变更的公司发生财务重述和负向重述的概率高于事务所未变更的公司;而被出具标准审计意见的公司在事务所变更后发生负向重述的概率高于事务所未变更的公司,但没有发现其发生财务重述的概率高于事务所未变更的公司;未更换事务所的公司其前期被出具标准审计意见与发生财务重述的概率负相关,而与负向财务重述的关系不显著。     

盈余管理、信息风险与审计意见

盈余管理和信息风险是影响审计意见的两个重要因素。已有研究主要关注当期盈余管理与审计意见的关系,少有关注信息风险对审计意见的影响。本文运用我国上市公司的数据,同时研究盈余管理和信息风险对审计意见的影响。检验结果表明,公司的信息风险与审计师出具非标意见概率显著正相关,而当期盈余管理与审计师出具非标意见的概率无显著相关性。这表明,审计师出具审计意见时主要考虑信息风险,而没有证据表明审计师出具审计意见时考虑了盈余管理。本文的研究结论深化了已有审计意见和审计质量决定因素方面的研究。     

会计事务所组织形式、法律责任与审计质量——基于签字审计师个体层面的研究

本文从签字审计师个体层面研究了会计事务所组织形式对审计质量的影响。与有限责任制相比,特殊普通合伙制将审计法律责任与风险落实到了签字审计师个人,增加了审计师的违规成本,因此审计师可能会变得更加独立和谨慎。研究表明,同一签字审计师同年在特殊普通合伙制身份下比在有限责任制身份下更容易出具非标审计意见,其审计公司的盈余管理水平更低,审计质量更高。同时,我们还发现,事务所从有限责任制转变为特殊普通合伙制以后,相同签字审计师转制后出具非标审计意见的可能性更高,而且被审计公司的盈余管理水平更低,审计质量也明显提高。这些结果为我们判断2010年以来我国推动事务所转制为特殊普通合伙制的政策提供了直接的经验证据,表明特殊普通合伙制对审计师的审计行为产生了预期的政策治理效果,有助于事务所做强。     

审计意见和年报披露会影响盈余质量吗?

本文使用沪深两市A股上市公司的面板数据,分析了审计意见和年报披露及时性与盈余质量的关系,认为二者与盈余质量之间存在显著的相关性:首先,年度财务报告被出具非标类型审计意见的上市公司,盈余质量较低;其次,年报披露越及时的公司,盈余质量越高。另外我们的研究结果还表明年报被出具非标审计意见的公司,会更晚披露财务报告,验证了变更年报预约披露日期(延迟披露)的公司则更容易被出具非标审计意见。     

盈余管理会影响审计意见——基于两类盈余管理的经验研究

研究发现,会计选择盈余管理和真实活动盈余管理都是影响审计师出具审计意见的重要因素。盈余管理程度越大,被出具非标准审计意见的概率越高,随着公司两种方式盈余管理程度的增大,出具更差类型审计意见的概率越高。     

审计意见的决定因素：来自中国上市公司的证据

利用中国上市公司和相应会计师事务所2001—2003年的综列数据,本文研究了审计意见和会计师事务所规模、上市公司的风险和盈余管理等因素之间的关系。本文发现有破产风险的、进行盈余管理的或小规模的上市公司更可能得到非标准审计意见。如果它们又是大会计师事务所的客户,则得到非标意见的概率更大。本文不支持合资会计师事务所的审计质量更高的结论。     

Political embeddedness and firms’ choices of earnings management strategies in China

We examine whether and how political embeddedness influences financial reporting quality in China by investigating how government ownership and political connections affect Chinese listed firms’ choices of earnings management strategies. The results show that state-owned enterprises (SOEs), and in particular, central SOEs, are more likely to substitute accrual-based earnings management strategies with costlier but less detectable real earnings management strategies than non-SOEs. The results also indicate that politically connected enterprises (PCEs) are more likely to employ less detectable real earnings management strategies than non-PCEs, so much so that PCEs’ total earnings management level is higher than that of non-PCEs.     

高质量内部控制能抑制盈余管理吗?——基于自愿性内部控制鉴证报告的经验研究

本文以2009年度A股非金融类上市公司为研究对象,探讨高质量内部控制对盈余管理的影响。结果表明:高质量内部控制能够抑制公司的会计选择盈余管理和真实活动盈余管理;披露内部控制鉴证报告的公司具有更低的盈余管理程度;尤其是获得合理保证的内部控制鉴证报告的公司,其盈余管理程度更低。采用处理效应模型校正自选择性偏差后,上述结论更为稳健。     

信息披露与国有股权私有化中的盈余管理

国有股权私有化是我国国有企业改革的重要措施。国有股权私有化过程中是否存在影响国有股权转让价格的盈余管理行为,以及如何抑制这种盈余管理,是我国国有企业改革中需要予以回答的重大问题。本文以我国通过控制权转移进行私有化的上市公司为样本,研究了国有股权私有化过程中的盈余管理以及信息披露对盈余管理影响的问题。研究发现,国有企业在国有股权私有化前1年和当年的操控性应计项目显著小于0,而私有化后的第1年显著大于0;及时披露国有股权私有化信息的公司在私有化前的操控性应计项目显著大于滞后披露信息的公司。以上结果表明,国有企业在国有股权私有化前存在降低收益的盈余管理行为,信息及时披露对私有化前的盈余管理有显著的抑制作用。本文的研究结论对规范我国国有企业改制和国有产权转让行为具有重要启示。     

Internal governance structures and earnings management

This paper investigates the role of a firm's internal governance structure in constraining earnings management. It is hypothesized that the practice of earnings management is systematically related to the strength of internal corporate governance mechanisms, including the board of directors, the audit committee, the internal audit function and the choice of external auditor. Based on a broad cross‐sectional sample of 434 listed Australian firms, for the financial year ending in 2000, a majority of non‐executive directors on the board and on the audit committee are found to be significantly associated with a lower likelihood of earnings management, as measured by the absolute level of discretionary accruals. The voluntary establishment of an internal audit function and the choice of auditor are not significantly related to a reduction in the level of discretionary accruals. Our additional analysis, using small increases in earnings as a measure of earnings management, also found a negative association between this measure and the existence of an audit committee.     

A game of accounting numbers in asset pricing: Evidence from the privatization of state-owned enterprises

This study examines a public policy issue: whether government officials engage in earnings management to collude with private investors in the privatization of state-owned enterprises (SOEs). We find that the managers of listed Chinese SOEs, who are de facto bureaucrats, employ income-decreasing earnings management to reduce the price of shares to be sold to private investors. We also find that more aggressive income-decreasing earnings management is associated with a lower CEO turnover rate in the year following the privatization. These findings highlight the need to consider the opportunism of government agents when accounting information is used in redistribution of state assets.     

An analysis of the effect of mandatory adoption of IAS/IFRS on earnings management

This paper examines whether mandatory adoption of international accounting standards, IAS/IFRS, by French companies is associated with lower earnings management. In addition, the impact of six factors that may be related to earnings management level are also considered: the independence and the efficiency of the board of directors, the separation of roles of CEO and Chairman of the board, the existence of an independent audit committee, the existence of block shareholders, the quality of the external audit and the listing on foreign financial markets.Based on a sample of 353 French listed groups relating to the period 2003–2006, our results show that the mandatory adoption of IAS/IFRS is associated with a reduction in the earnings management level. In addition, the independence and the efficiency of the board of directors, the existence of an independent audit committee, the existence of block shareholders, the quality of the external audit and the listing on foreign financial markets are important factors for enforcement of IAS/IFRS in France. Mandatory adoption of IAS/IFRS has decreased earnings management level for companies with good corporate governance and those that depend on foreign financial markets.     

会计师事务所组织形式、盈余管理与IPO折价

会计师事务所组织形式由有限责任制变为特殊普通合伙制,增加了审计师的法律责任,提高了审计的鉴证价值和保险价值,有利于审计师在 IPO 审计过程中更好地发挥信息中介作用。以保荐制下 IPO公司为样本,实证考察事务所组织形式对 IPO 盈余管理和 IPO 折价的影响。研究发现,相比有限责任制事务所,特殊普通合伙制事务所审计的发行公司的正向盈余管理水平更低,IPO 折价率也更低。研究结论表明事务所转制后,审计师加强了对发行公司盈余管理行为的约束,提高了 IPO 定价效率,监管部门推动的事务所转制对 IPO 市场具有积极治理效果。     

Former auditors on the audit committee and earnings management: Evidence from African banks

This paper investigates whether former auditors on the audit committee constrain earnings management through loan loss provisions. Based on an analysis of the annual reports of 82 African listed banks over the period 2011–2016, findings show that the presence of former auditors on an audit committee is associated with lower earnings management. This result suggests that audit committee members with auditing expertise and background contribute to effective monitoring of management’s accounting practices. Furthermore, results reveal that the reducing effect on earnings management of former auditors is strongest for directors who are unaffiliated with the bank’s current external auditor.     

Earnings Behaviour of Financially Distressed Firms: The Role of Institutional Ownership

Using a sample of 859 U.S. bankruptcy-filing firms over the period 1986–2004, we examine the earnings behaviour of managers during the distressed period by looking at sources of abnormal accruals prior to the bankruptcy-filing year. Results show that managers of highly distressed firms shift earnings downwards prior to the bankruptcy filing. We test and provide evidence in support of two potential contributing factors. First, top-level management turnover among distressed firms leads new managers to earnings bath choices during the distressed period. Second, qualified audit opinions exert pressure on managers to follow more conservative earnings behaviour during the distressed period. Evidence is also provided that the management of distressed firms with lower (higher) institutional ownership has greater (lesser) tendency to manage earnings downwards. Results also show that higher institutional ownership mitigates the negative abnormal returns of firms with top management turnover. To the authors' knowledge, this is the first study that attempts to examine whether institutional ownership relates to market reaction in conjunction with a top management turnover or a qualified audit opinion during the distressed period. Prior studies focused on the investigation of earnings management or institutional ownership (separately) during the distressed period, but did not examine if the effect of institutional ownership on earnings behaviour also influences subsequent returns. Thus, the results of this study should be of interest to analysts, standard setters and regulatory bodies since our results show that management turnover, qualified audit opinions and firm governance mechanisms affect the quality of earnings and the level of abnormal returns.     

Audit committee accounting expertise,expectations management,and nonnegative earnings surprises

We investigate whether accounting expertise on audit committees curtails expectations management to avoid negative earnings surprises. Controlling for the endogenous choice of an accounting expert, we find that firms with an accounting expert serving on the audit committee exhibit: (1) less expectations management to avoid negative earnings surprises; (2) less nonnegative earnings surprises through expectations management; and (3) more nonnegative earnings surprises that are less susceptible to manipulations of both realized earnings and earnings expectations. We find, however, that the inclusion of an accounting expert on the audit committee curtails expectations management only in the interim quarters. While Brown and Pinello (2007) find a greater magnitude of downward revisions in analysts’ forecasts in the fourth quarter, they also document a lower incidence of nonnegative earnings surprises. Together, this suggests that with an accounting expert, audit committees likely view the fourth quarter downward revisions as driven more by guidance than by manipulation, thus focusing on curbing only expectations management in interim quarters.
