Valuing Initial Public Offerings Using Article 11 Pro Forma Financial Information in the Prospectus*

We investigate whether Article 11 pro forma financial information assists investors in valuing IPOs. While the SEC expects it to be helpful in assisting investment decisions, Article 11 pro forma financial information is based on registrants' understanding and assumptions, and registrants can exercise their own judgment when preparing pro forma financial statements. It is therefore an empirical question whether the information contained in pro forma financial statements is useful to investors. We examine the association between pro forma adjustments of earnings and book value of equity and the IPO offer value and find asymmetric results. While positive pro forma adjustments of earnings and book value of equity are positively associated with the IPO offer value, negative pro forma adjustments of earnings and book value of equity are negatively associated with the IPO offer value, suggesting that negative pro forma adjustments are priced as growth opportunities. Additional analyses reveal that the association between pro forma adjustments of book value of equity and the IPO offer value varies across different time periods and industries and that pro forma adjustments of book value of equity are initially mispriced by investors. In contrast, we do not find similar results for pro forma adjustments of earnings. Further empirical tests show that the asymmetric results of mispricing of pro forma adjustments of earnings and book value of equity may be explained by the requirements of Article 11 of Regulation S‐X for pro forma adjustments dictating that adjustments to earnings reflect only recurring items while adjustments to book value reflect both recurring and nonrecurring items.     

中国A股市场IPO抑价影响因素的实证研究

IPO抑价是全球资本市场的普遍现象,是一级市场定价效率低下和二级市场交易不规范的具体表现。IPO抑价使得资本市场资源配置效率低,同时也会产生众多金融风险。在中国IPO抑价率过高,普遍达到100%以上,超过了国外成熟市场和很多的新兴市场。在对国内外相关研究进行综述之后,再构建模型引入实证分析,对理论在国内的适用性进行研究进而探寻导致IPO抑价的原因。信息不对称是导致IPO抑价的主要原因,同时承销商声誉、"公司信号"、资本市场"羊群效应"也有一定的影响。

REASONS FOR DELISTING AND CONSEQUENCES: A LITERATURE REVIEW AND RESEARCH AGENDA

This paper discusses the literature on delisting, drawing on USA and international evidence. Given the great heterogeneity in delisting operations, we first consider the standard existing typology based on the initiator of the delisting (the stock market authorities, or the firm itself). Second, while managers often cite high compliance costs (especially due to Sarbanes–Oxley Act implementation) as the official reason for the voluntary delisting of their firm, we highlight that firms face different trade-offs in their delisting decision. We also examine the reasons for involuntary delisting, especially the delisting dilemma faced by stock market authorities when the firm violates the listing requirements. Next, we review the economic consequences of delisting in terms of value creation or value destruction for shareholders. Finally, noting gaps in the literature and other contrasting results, we propose suggestions for future research.     

盈余操控方式对创业板上市公司IPO后业绩的影响

通过对创业板上市公司从应计盈余管理和真实盈余管理两个视角比较不同盈余操控方式对IPO后企业业绩的影响。实证分析结果表明,创业板公司IPO前后同时实施应计项目操控和真实活动操控两种盈余操控行为。其中真实盈余管理是IPO后企业业绩下滑的深层次原因,且不同盈余操控方式对IPO后3年业绩影响具有时间差异。     

Venture capital trusts and the expiration of IPO lock-up provisions

Venture capital trusts (VCTs) were introduced to provide private equity capital for small expanding companies and to promote innovation. Investors in initial public offerings are rewarded with tax relief on the cost of lock-up provisions to stabilize the market. This paper examines the market reaction and trading activity around the expiration of lock-up provisions of 148 VCTs listed on the London Stock Exchange from 1995 to 2006. Downward-sloping demand curve theory suggests that an increased supply of VCT shares at the expiry date could shift their value to a new equilibrium at a lower price. Supporting this prediction, we document evidence of negative abnormal returns as well as permanent increases in the price discount relative to net asset value and trading volumes at and around the expiries of the required holding periods of VCTs. In addition, less negative abnormal returns, lower abnormal discounts and lower abnormal trading volumes are associated with VCTs that invest in AIM-listed companies due to lower information asymmetry, that experience lower prior performance due to a less pronounced disposition effect, and that are subject to a shorter lock-up horizon or are offering more generous tax benefits.     

IPO、公司治理与企业价值——资本成本视角的理论综述

本文认为,首次公开发行上市(IPO)是企业生命周期中的里程碑。企业IPO行为改变了公司资本结构,通过资本结构对公司治理发生积极作用(融资机制、价格机制和并购机制),使得公司治理在经营者激励、信息披露、投资者保护等方面得到改善将提升企业价值,进而实现企业价值最大化的理财目标。     

基于复合期权的创业板上市公司IPO定价研究

指出传统IPO定价方法用于具有高风险、高成长性等特征的高新技术企业IPO定价的缺陷,将实物期权概念引入IPO定价研究中。根据高新技术企业项目投资的特征,引入复合期权建立相应的数学模型,采用复合期权方法建立高新技术企业的IPO定价模型。最后,通过算例分析说明该模型在实践运用中具有一定的借鉴意义。     

投资者的异质预期对IPO抑价的影响

针对IPO抑价中的有意抑价和无意抑价问题,运用行为金融理论,在以机构投资者利益最大化推导出机构投资者需求函数的基础上,研究了散户和机构投资者的同质和异质预期对IPO抑价的影响,并进行抑价进行比较分析。研究表明:机构投资者具有有意抑价的激励;当机构投资者与散户对新股价值不存在分歧时,IPO抑价中只有有意抑价,而无无意抑价;当机构投资者与散户对新股价值存在分歧时,分歧越大,IPO抑价越高,而抑价中的有意抑价不变、无意抑价增大。     

风险投资参与对中资企业首次公开发行折价的影响——不同证券市场的比较

本文考察中资企业在不同市场上市时风险投资的参与是否影响首次公开发行折价。研究发现,在大陆中小板和香港主板市场上市的中资企业中,有风险投资参与的企业IPO折价显著高于无风险投资参与的企业,支持声誉效应假说,即风险投资机构以IPO折价来提早退出投资项目,以此来建立自己的声誉,吸引更多的资金流入。在美国市场风险投资的参与对IPO折价则没有显著影响。本文进一步研究发现从业时间短的风险投资机构,其参与投资的公司上市时的历史也较短;风险投资进入企业的时间越长,IPO折价水平也越高。这两个检验都验证了风险投资机构通过IPO折价提早退出投资项目,进一步支持了声誉效应假说。
