Board, audit committee and restatement-induced class action lawsuits

We examine the influence of monitoring provided by the board and audit committee on the probability of restatement-induced securities class action lawsuits using a sample of firms that have restated earnings in the period of 1997-2002. Logistic regression of the probability of restatement-induced class action lawsuits indicates a negative association between proportion of independent board members and the likelihood of restatement-induced class action lawsuits. We also find that when the market reacts more negatively to restatement announcements, shareholders are more likely to initiate a class action lawsuit. Finally, we document that restatement of revenues is positively associated with the likelihood of restatement-induced shareholder litigation. Our results are robust after controlling for the restatement initiator, restatements categorized as irregularities and Blue Ribbon Recommendations.     

卖空与盈余质量——来自财务重述的证据

本文利用2006-2014年中国A股上市公司数据,运用双重差分和安慰剂检验,考察卖空对财务重述的影响。研究发现,加入融券标的后,相较于不能被卖空的公司,融券标的公司发生财务重述的可能性显著降低,这种治理作用在金融市场欠发达和治理水平较差的公司更加明显。进一步研究发现,卖空机制可以通过增加激励合约的有效性和吸引分析师跟踪来减少财务重述。最后,使用可操控应计项目和是否报告微利作为盈余质量的代理变量进行稳健性检验,发现上述结论依然成立。因此,放开卖空限制,有助于改善上市公司信息披露质量和完善公司治理结构。     

Opaque auditor dismissal disclosures: What does timing reveal that disclosures do not?

Auditor resignations provide a clear signal of accounting problems or heightened audit risk; however, registrants label the vast majority of auditor changes as dismissals, which carry more ambiguity. Motivated by the opacity of current dismissal disclosures, this study explores the usefulness of these disclosures compared to an alternative signal – the timing of the dismissal within the reporting year – for inferring the causes and implications of dismissals. Dividing the reporting year into key periods, we find that the probabilities of future restatements, material weaknesses, and delistings following a dismissal generally increase within the reporting year while negative circumstances disclosed do not. Analyses suggest that the timing patterns are caused by burgeoning, yet undisclosed, conflicts between the client and the outgoing auditor, rather than by transition difficulties involving the new auditor (as prior literature claims). The timing patterns strongly persist after controlling for negative circumstances that registrants disclose in the dismissal filing, suggesting that the disclosures are not fully revealing. In fact, disclosed negative circumstances have no incremental predictive power for future restatements and delistings. Our results suggest a severe lack of informativeness of current disclosures and support previous calls for improvement of dismissal disclosure regulation.     

信用评级变动能反映企业真实财务信息吗?——基于财务重述的视角

本文以2007-2018年拥有主体信用评级的A股上市公司为研究对象,利用企业财务错报在未来被重述这一场景,检验主体信用评级变动能否反映企业真实财务信息。研究发现,评级机构在发债企业财务错报年显著下调了主体信用评级,而在重述公告发布年没有上述现象,这表明主体信用评级下调反映了企业的真实财务信息。在控制内生性影响后,结论仍然成立。进一步研究发现,发债企业当期财务错报涉及盈余时,主体信用评级被下调的幅度更大,说明评级机构更加关注与盈余相关的财务信息。机制分析表明,评级机构维护自身声誉是主体信用评级变动能够反映企业真实财务信息的主要机制。此外,主体信用评级被下调还导致了资本市场投资者的负面反应。本文的研究结果为主体信用评级变动反映企业真实财务信息提供了直接的证据支持,揭示了主体信用评级的信息含量,也对理解中国情境下评级机构调整主体信用评级的行为动机提供参考。
