财务重述对债务期限结构影响分析

本文验证了财务重述现象是否会影响上市公司的债务期限结构。结果显示,发生过财务重述上市公司其债务期限结构要明显短于非重述公司;发布过更正公告、补充及更正公告上市公司其债务期限结构明显短于发布补充公告公司;重述公告涉及会计内容上市公司债务期限结构要明显短于没有涉及会计内容公司。且债务期限结构同公司规模、资产负债率、盈利能力等显著正相关,与资产周转率、高管持股比例显著负相关。     

上市公司财务重述对市场反应的实证研究

文章选取财务重述对市场造成的影响作为研究对象,采用事件研究法,选取(-200,-6)为估计期,分别计算每支股票的日超额回报率,并对所有样本的日超额回报率和累计超额回报率进行单样本T检验,以研究财务重述的市场反应。研究结果证明,财务重述行为发生前后较短的事件窗口期内,市场会做出显著的负面反应。且更正公告和传递坏消息的财务重述公告会给市场带来显著的负面影响,补充及更正公告、传递消息性质不确定的财务重述公告会造成较为显著的负面影响。而补充公告和传递好消息及无影响消息的财务重述公告不会给市场造成明显影响。

文章以2012—2014年间中国上交所发生财务重述的A股上市公司年报和季报为研究对象,对财务报告重述的特征进行了多角度分析。研究结果表明,当前财务重述具有五个外在特征:(1)财务重述现象具有一定的普遍性;(2)制造业以及经济欠发达地区的上市公司较容易发生财务重述;(3)部分公司是财务重述的"常客";(4)重述公告大部分属于更正公告;(5)重述公告整体及时性较强,其中补充公告滞后时间最长。具有三个内在特征:(1)涉及治理问题的财务重述最多;(2)重述中低级错误多;(3)上市公司财务报告披露格式不规范。以上研究成果对深入了解我国上市公司财务重述现象、特征以及发展趋势具有一定意义。

上市公司财务报表重述的趋势与特征:2004-2008

通过对中国A股上市公司2004年-2008年财务报表重述公告的五年趋势与特征研究发现,公司多次进行财务报表重述的现象严重,调减利润的财务报表重述数目每年基本稳定在75%左右,报表重述涉及的主要会计问题包括成本费用、估值与计价、税费相关、股权相关的投资损益以及收入等。公司的自愿性重述相对较低,而且通常选择重述公告的时机,导致重述公告的市场反应较弱,总体累计异常回报率(基于流通市值加权平均市场回报率调整)的中位数仅为-0.5%,均值为-0.2%。     

我国中小板上市公司财务重述状况分析

本文以2005年至2009年85家中小板上市公司发布的89份年报补充及更正公告作为研究对象,从年度分布、重述频数、重述行业与地域分布等角度系统分析我国中小板上市公司财务重述状况。结果发现:中小板上市公司财务重述现象逐渐减少,重述公司的行业与地域分布较为均衡;因会计问题和技术问题而进行重述的公司保持较高比例,涉及核心财务指标的重述约占重述内容总数的三分之一,且呈上升趋势。

An empirical investigation of environmental performance and the market value of the firm

This paper analyzes the shareholder value effects of environmental performance by measuring the stock market reaction associated with announcements of environmental performance. We examine the market reaction to two categories of environmental performance. The first category includes 417 announcements of Corporate Environmental Initiatives (CEIs) that provide information about self-reported corporate efforts to avoid, mitigate, or offset the environmental impacts of the firm's products, services, or processes. The second category includes 363 announcements of Environmental Awards and Certifications (EACs) that provide information about recognition granted by third-parties specifically for environmental performance. Although the market does not react significantly to the aggregated CEI and EAC announcements, we find statistically significant market reactions for certain CEI and EAC subcategories. Specifically, announcements of philanthropic gifts for environmental causes are associated with significant positive market reaction, voluntary emission reductions are associated with significant negative market reaction, and ISO 14001 certifications are associated with significant positive market reaction. The difference between the market reactions to the CEI and EAC categories is statistically insignificant. Overall, the market is selective in reacting to announcements of environmental performance with certain types of announcements even valued negatively.     

上市公司谴责公告研究与分析

公开谴责制度是证券交易所对上市公司违规信息披露监管的重要制度,对规范上市公司信息披露行为起着重要作用。本文以1999￣2005年被公开谴责的上市公司为研究对象,从谴责公告的年度分布、内容类型和再处罚情况等方面,分析了上市公司谴责公告的现状以及存在的问题,提出了加强上市公司信息披露监管的建议。     

上市公司财务报告补充更正问题研究

近几年来,我国上市公司发布财务报告补充更正公告的现象已经相当普遍。本文通过对1999至2003年期间A股上市公司发布的所有定期财务报告(包括年报和半年报)的补充、更正公告进行实证分析发现,频繁补充说明的事项几乎涉及上市公司各个方面,反映了财务信息的披露仍然存在很多不规范和随意性；而频繁更正的事项中有一半以上都与利润相关,可见这一问题背后可能隐藏着部分上市公司利用财务补充更正公告粉饰财务信息的恶意行为。这些行为不仅有损上市公司信息披露的质量和规范,也反映了市场监管的漏洞。为此,本文最后提出了几点政策建议。     

财务报表重述与公司非效率投资行为

以在2006—2010年的年报附注中披露会计差错更正的上市公司为重述样本,运用倾向得分匹配等两种方法产生控制样本,实证检验财务报表重述公告前后公司投资效率的变化,为财务报告信息质量与公司投资效率间的因果联系提供了更为直接的证据。结果发现：（1）财务报表重述之前,存在融资约束的重述公司会投资不足,不存在融资约束的重述公司倾向于投资过度;（2）报表重述公告后,重述公司投资效率显著提高。     

Inter-industry differences in layoff announcement effects for financial institutions

This study expands the examination of workforce layoffs by banks to include non-bank financial institutions and explores inter-industry differences in market reactions to layoff announcements. In examining inter-industry differences, we control for variables that influence the market’s reaction to a layoff announcement, such as firm size, the size of the layoff, the reason given for the layoff, and the governance structure of the firm. We provide evidence of inter-industry differences in market reaction to layoff announcements by financial institutions, with banks experiencing more favorable stock-price reactions than other types of regulated firms. These results provide evidence that bank regulation reduces asymmetric information surrounding managerial announcements to a greater degree than the regulation of other types of financial institutions.

Capital market reactions to earnings announcements: empirical evidence on the difference in the information content of IAS-based earnings and EC-Directives-based earnings

Listing on a foreign stock exchange and the aim to attract international investors usually forces European quoted companies to adapt information supplied in financial statements to different information needs of international investors. Because of the dominance of the American stock market, this adaptation raises especially the question whether Anglo-American-oriented accounting standards (for instance IAS — International Accounting Standards) convey a higher information content for investors than continental-Europe-oriented accounting standards (for instance EC-Directives). The study examines the information content of earnings announcements, i.e. abnormal returns resulting from un-expected earnings, for a sample of Swiss quoted companies which have changed the accounting standard used for presenting Swiss GAAP consolidated financial statements to either EC-Directives or IAS and can therefore contribute to this discussion. The results of the study suggest that IAS-based earnings announce-ments convey a statistically significant higher information content than earnings announcements based on the Swiss GAAP if a variance-approach is used. For investors in the Swiss capital market, the switch from Swiss GAAP to IAS has therefore increased the information content of financial statements. But comparing IAS-based and EC-Directives-based earnings announcements, the results suggest that for investors IAS-based earnings do not possess a statistically significant higher information content than EC-Directives-based earnings. This result has been achieved despite the fact that for Swiss financial analysts financial statements based on IAS convey a significant higher information content than financial statements based on EC-Directives. Avoiding problems in specifying a model for unexpected earnings by standardizing the mean of the abnormal returns of each event window to a positive value does not lead to a different conclusion if the variance approach is used.     

Stock price reactions to stock dividend announcements: A case from a sluggish economic period

The 2007 financial crisis and the Great Recession that followed resulted in a loss of confidence among investors, and regaining their full trust and confidence has been a challenge for companies. Although economic growth has been volatile throughout the postwar World War II period, recent growth (2008–2015) has been remarkably weaker than in the previous low-growth period (1974–1995). The 2006–2015 period is often characterized by sluggish economic growth. This study investigates stock price reactions to stock dividend announcements, 30 days before and after the announcement dates, of publicly traded companies in the period 2006–2012. We use an event study methodology for 460 events and daily stock price data for companies in the CRSP historical data set. The study shows a significant reaction in stock prices around the event date. On average, stock prices reacted positively to stock dividend announcements. However, compared to previous findings of abnormal returns (5.9%), results from this study show small abnormal returns (about 1.81%) attributable to stock dividend announcements that are cumulative of the announcement day and up to 3-day post-announcement days. Our estimates are even lower than the 2.01% stock price reaction obtained in the 1987–1996 period.
