论上市公司会计报表粉饰行为的识别及其防范

近几年我国证券市场出现的几宗大案使人们对会计报表的粉饰有了极大的关注,本文通过对上市公司报表粉饰的动机、常用手段的分析,提出了识别会计报表的粉饰的有效方法,以提高广大投资者识别盈余管理等粉饰方法的能力。     

Mutual fund flows and window-dressing

We use a sequential game to analyze an agency problem in the mutual fund industry where a representative fund manager considers window-dressing his portfolio holdings for the purpose of attracting fund flows from a representative investor. The manager is motivated to window-dress to improve the investor's perception of managerial skill which may positively affect fund flows in the next period. However, the investor may suspect window-dressing and thus downgrade perceived managerial skill. The model supports a Bayesian Nash equilibrium where the manager window-dresses only when receiving a low return in the first period and the investor withdraws funds only when observing low returns in both periods. Consequently, we show that window-dressing is a rational behavior even when fund outflows may result.     

Window-dressing in German inter-war balance sheets

German accounting rules value assets and liabilities asymmetrically and thus lead to grossly distorted balance sheets. In the inter-war debate on a reform of disclosure regulation, financial experts considered the (undisclosed) tax balance sheet, which had to be drawn up separately for the corporate tax assessment, as a paradigm for adequate financial disclosure. However, due to tax secrecy they were barred from analysing tax documents. Using archival evidence, we analyse tax balance sheets as a means of assessing the reliability of disclosed balance sheets of the inter-war period. It emerges that companies overstated their profits in the mid- and late-1920s, but grossly understated them in the Nazi economy.     

Factors affecting secondary share offerings in the IPO process

We investigate whether the sale of secondary shares in the IPO process is affected by an issuing firm's market-timing and window-dressing activities. We find that secondary share offerings in IPOs exhibit positive autocorrelation, and the positive autocorrelation is mainly affected by the overall stock market return. Similar to the IPO wave, this finding suggests that favorable market conditions attract existing pre-IPO shareholders to sell their shares in IPOs and cause the clustering of secondary share offering in IPOs. In addition, we find that window dressing has a significant effect on both the probability of secondary share offering and the proportion of secondary shares offered in an IPO. The result is robust after controlling for firm age, industry affiliation, and other factors. Our result also indicates that the number of firms offering secondary shares in IPOs, the probability of secondary share offerings, and the proportion of secondary shares offered in IPOs are significantly lower in the Internet bubble period.     

发审委关联、业绩粉饰与IPO审核决策

发审委关联对资本配置产生的影响已引发广泛关注,但对其影响资本配置决策的机制的关注还明显不足。以2007年9月24日至2017年8月31日的IPO申请为对象,研究了IPO企业通过其聘任的或其保荐机构聘任的会计师事务所与发审委形成的关联影响发审委决策的机制。研究发现:发审委关联的存在提高了IPO企业报告的历史业绩;报告业绩和发审委关联都能独立地提高审核通过率;而上述情形主要发生在民营企业。这意味着报告业绩并未完全成为发审委关联影响发审委决策的媒介,申请企业在利用业绩粉饰配合审核权限以达到上市目的。
