Are Securitizations in Substance Sales or Secured Borrowings? Capital‐Market Evidence*

Two standard‐setting approaches have emerged globally to guide the choice of accounting for securitizations: the control and components approach (SFAS No. 125 and SFAS No. 140) and the risks and rewards transfer approach (IAS No. 39). A lack of consensus about derecognition accounting is a major impediment to achieving convergence in global standards that must be resolved. Thus, both SFAS No. 140 and IAS No. 39 will be reexamined, and evidence pertinent to the debate is timely and important. In this study, we present evidence consistent with the view of credit‐rating analysts, who view many securitizations as, in substance, secured borrowings. Specifically, for a sample of originators applying sale accounting guidance in SFAS No. 125 / 140 during the period 1997‐2003, we show that off‐balance‐sheet debt related to securitizations has, on average, the same risk‐relevance for explaining market measures of risk (that is, CAPM beta) as on‐balance‐sheet debt. We also find that, in a returns and earnings association framework, the pricing multiple on securitization gains declines as the amount of off‐balance‐sheet debt increases, implying that investors take off‐balance‐sheet debt into account when assessing the valuation‐relevance of such gains. For those who advocate the control and components approach to securitization accounting, our results suggest that, at least for frequent securitizers, the put option arising from implicit recourse is a “missing piece” that is not currently accounted for when calculating securitization gains. Our results challenge the extant measurement standards in SFAS No. 140.

The impact on stock prices of deferral and elimination of internal control audit requirement for small firms

This paper examines the cumulative market reaction to the events related to deferral of internal control audit requirement under the Sarbanes-Oxley Act of 2002 and its elimination under the Dodd-Frank Act of 2010 for nonaccelerated filers (small firms). We document that small firms experienced negative cumulative abnormal returns around these events; and the differences between the cumulative abnormal returns for small firms and the two control groups (accelerated and large accelerated filers) were negative and significant at the 1% level. These results support the notion that market participants value the reliability of financial information irrespective of the firm size. Within the small firms, we find no firm characteristic significantly explains the market reaction to the events considered. That is, all small firms lost market value in reaction to the events that delayed and eliminated their internal control audit requirement.     

谁从增加的财政转移支付中受益——基于中国县级数据的实证分析

基本公共服务均等化要求财政转移支付应有效保障贫困地区提供大致均等化公共服务的财政能力。本文运用边际受益归宿分析技术,实证评估了2003—2007年中国县(市)一级财政转移支付资金的边际受益分配状况。研究结果显示:贫困县(市)从增加的一般转移支付补助中受益更高;对于调整工资补助和农村税费改革补助,富裕县(市)是新增财政转移支付资金的最大受益者;专项转移支付增量资金的受益分配也存在配置失效问题。基于实证分析结论,我们的政策建议是:提升一般性转移支付补助在财政转移支付资金中的占比;制定更加\"亲穷\"的一般性财力转移支付制度,增强其均等化功能;规范专项转移支付分配机制。
