Valuation and optimal strategies of convertible bonds

This article presents a contingent claim valuation of a callable convertible bond with the issuer's credit risk. The optimal call, voluntary conversion, and bankruptcy strategies are jointly determined by shareholders and bondholders to maximize the equity value and the bond value, respectively. This model not only incorporates tax benefits, bankruptcy costs, refunding costs, and a call notice period, but also takes account of the issuer's debt size and structure. The numerical results show that the predicted optimal call policies are generally consistent with recent empirical findings; therefore, calling convertible bonds too late or too early can be rational. © 2006 Wiley Periodicals, Inc.

Determinants of callable convertible bond prices

A new model is proposed in this paper that efficiently estimates the after-market prices of callable convertible bonds. The proposed model is shown to be fairly stable over time and across firm size. The paper also shows that, among other factors, call price and bankruptcy indicators are significant determinants of callable convertible bond prices, suggesting that a priori specification regarding the exercise of call option and the ignorance of firm's possible bankruptcy, as done in past studies, are inappropriate for convertible bond price estimation.     

Are green bonds priced lower than their conventional peers?

The green bond market's rapid growth has alerted issuers and investors to this sustainable area of investment. This study ascertains whether green bonds are priced lower than conventional bonds—whether a negative green bond premium exists in both Chinese and global bond markets—and the driving forces behind any such green bond premium. First, an event study is set up to observe stock market's reaction upon issuance of green bonds to test whether green bonds are embedded with additional value by improving the issuer's equity market performance. Then, using the matching method and a two-layer regression process, the study estimates the green bond premium in the Chinese and global markets, respectively, and analyses factors affecting the green bond premium. The event study reveals that green bond issuance could reduce the issuer's equity return performance. The regression models found no significant negative green bond premium in either Chinese or global markets, indicating that green bonds are not priced significantly lower than conventional bonds. However, global market models show that issuing green bonds in CNY could reduce the green bond premium, unlike in USD or EUR.     

A NONZERO‐SUM GAME APPROACH TO CONVERTIBLE BONDS: TAX BENEFIT,BANKRUPTCY COST,AND EARLY/LATE CALLS

Convertible bonds are hybrid securities that embody the characteristics of both straight bonds and equities. The conflicts of interest between bondholders and shareholders affect the security prices significantly. In this paper, we investigate how to use a nonzero‐sum game framework to model the interaction between bondholders and shareholders and to evaluate the bond accordingly. Mathematically, this problem can be reduced to a system of variational inequalities and we explicitly derive the Nash equilibrium to the game. Our model shows that credit risk and tax benefit have considerable impacts on the optimal strategies of both parties. The shareholder may issue a call when the debt is in‐the‐money or out‐of‐the‐money. This is consistent with the empirical findings of “late and early calls.” In addition, the optimal call policy under our model offers an explanation for certain stylized patterns related to the returns of company assets and stocks on call.     

可转债发行公司经营绩效实证研究

对中国上市公司2000-2004年间发行的可转债进行研究,统计检验结果发现,可转债发行后两年内,发行公司经营绩效有小幅下降,与行业规模组对比,发行可转债的公司属于绩优公司,发行前后各项绩效指标都高于行业规模组,而与增发配股组比较,二者不存在显著差异,发行后转债组的成长性指标高于增发配股组。     

预期转股冲击与企业杠杆调整——基于可转债的断点回归分析

股票价格高于转股价格时可转换债券内嵌期权由虚值变成实值状态,可转债持有者可能自愿转为股票对企业而言是一种外生的杠杆率下降冲击。文章从可转债预期转股冲击视角,采用断点回归分析的方法,探讨预期转股冲击对企业杠杆调整的作用程度和影响路径,同时分析预期转股冲击对不同来源负债的影响差异,并检验债务累积风险不同的企业杠杆调整的异质性。研究发现：企业增加当期杠杆率以应对预期转股冲击,预期转股冲击通过增加股价信息含量和提高股票流动性的路径影响企业杠杆调整,其显著提高经营杠杆而不影响金融杠杆。进一步分组检验表明,债务累积风险低的企业对预期转股冲击导致的预期杠杆率下降更为敏感,积极调整企业杠杆率,预期转股冲击不会叠加债务累积风险高的企业杠杆率。可转债融资工具有助于企业实现稳杠杆。     

上市动机、投资者情绪与首次公开募股市场收益

文章以发行人筹资收益最大化为假设,对市场热季周期下发行人、承销商与投资人三者之间的博弈过程以及投资者情绪对首次公开募股(IPO)市场定价的影响机制进行研究.研究结果表明,发行人最优发行数量小于市场需求数量、承销商定价低于市场需求价格的目的在于确保发行成功和获取日后收益;投资者高亢的投资情绪可以对IPO市场短期收益正偏和长期收益负偏成为普遍现象进行解释.     

我国可转债转股价调整条款设计存在的问题与修正建议

可转债转股价格调整条款设计的基本原则是要使可转债是红利保护的，要实现这一目标，必须将转股价格和股票价格进行同比例调整。我国可转债发行过程中转股价格调整条款对现金红利、增发和配股的处理办法在一般情况下基本符合红利保护的原则，但在现金红利数额较大，增发和配股比例比较高的情况下，必须根据更科学的方法来调整转股价格。     

可转换债券融资对我国上市公司价值的影响研究

可转换债券兼有股权融资和债权融资的两种效用,通常会促使投资者对转股时机与转股数量有不同的决策,这些决策对发行可转换债券的公司价值有不同影响。文章通过建立影响公司价值的分析模型,探讨我国上市公司发行可转换债券对公司价值所产生的影响,并利用我国上市公司1998年至2014年期间发行可转换债券的样本数据进行实证分析。研究发现：上市公司进行可转换债券融资后,公司价值会因其偿债能力变化而下降;国有股权比例之于公司价值的影响,是通过影响公司经理人经营行为来实现的;成长性不同的公司在债券存续期内的公司价值变化,并不存在显著差异。文章基于委托代理角度对可转换债券影响我国上市公司价值展开研究,在一定程度和范围内拓宽了公司治理问题的分析空间。     

可转换债券发行的长期股票市场价格绩效研究

应用长期事件研究法,对2000-2004年间发行可转换债券的上市公司的长期市场绩效表现进行了实证研究。研究结果表明,可转债发行前后,可转债标的公司的长期股票价格绩效在绝大多数区间上显著优于行业、规模与权益市值对面值比率的对照组,也显著优于等权加权和总市值加权的综合市场收益率;选择兼有债权和股票期权双重属性的可转债,在一定程度上可以维持标的公司股票价格长期绩效的优良表现。     

Contingent Capital,Real Options,and Agency Costs

This paper aims to clarify how contingent convertible bond (CoCo) as a debt financing instrument affects a firm's investment policy, agency cost of debt, and capital structure. We consider endogenous and exogenous conversion thresholds, respectively. Under the exogenous case, there is an explicit optimal fraction of equity allocated to CoCo holders upon conversion, such that the agency cost reaches zero. Numerical analysis demonstrates that under an endogenous conversion threshold, CoCo induces overinvestment, a higher leverage, a possible bigger agency cost, and a stronger incentive to increase risk. But if the conversion threshold is exogenously determined, almost the opposite holds true.     

Efficiency in IPO Issuance Processes?

Is the online auction an efficient mechanism for pricing initial public offerings (IPOs)? Its intent was to minimize first day price surges in IPOs, which represented “money left on the table” for issuers. Evidence from Google's IPO suggests that the online auction process may not have minimized the first day price surge, since 82 percent of the IPOs issued in 2004 using the traditional process experienced less of an increase. Furthermore, a comparison of auction IPOs with traditional IPOs issued in the same year and in the same threedigit SIC code suggests that 44 percent of the auction IPOs have greater first day price surges than their traditional counterparts. A broader comparison of the pricing behavior of auction IPOs with traditional IPOs presents a mixed picture and suggests that the size of underwriter may be an important factor. The mispricing that occurs in auctions may be due to an informational asymmetry on the part of small investors. This informational gap could arise because small investors lack access to the information sources that institutional investors have or because companies are not required to provide detailed information in the online process, inasmuch as they don't undergo the rigorous scrutiny of investment banks in the traditional bookbuilding process. This informational gap may be alleviated by the SEC reforms of the “quiet period” and by the issuer providing more detailed information on the uses of the funds.     

Reverse convertible bonds analyzed

We study the pricing of reverse convertible (RC) bonds. These are bonds that carry high coupon payments. In exchange, the issuer has an option at the maturity date to either redeem the bonds in cash or to deliver a pre‐specified number of shares. We find that Dutch plain vanilla and knock‐in RC bonds are, on average, overpriced by almost 6%. This overpricing is confirmed in a model‐free analysis with respect to option‐ and bond‐pricing models. We find that rational factors explain 23% of the documented overpricing. In addition, we find that the combination of financial marketing, framing, and the representativeness bias further increases our ability to explain the documented overpricing to more than 35%. © 2009 Wiley Periodicals, Inc.

Quantitative Easing and Liquidity in the Japanese Government Bond Market

The “Quantitative and Qualitative Monetary Easing” enacted immediately after the inauguration of Bank of Japan Governor Kuroda brought violent fluctuations in the prices of government bonds and deteriorated market liquidity. Does a central bank's government bond purchasing policy generally reduce market liquidity? Do conditions exist that can prevent such a decrease? This study analyzes how the Bank of Japan's purchasing policy changes influenced market liquidity. The results reveal that three specific policy changes contributed significantly to improving market liquidity: (i) increased purchasing frequency; (ii) a decrease in the purchase amount per auction; and (iii) reduced variability in the purchase amounts. These policy changes facilitated investors' purchase schedule expectations and helped reduce market uncertainty. The evidence supports the theory that the effect of government bond purchasing policy on market liquidity depends on the market's informational environment.

The valuation of inflation‐indexed and FX convertible bonds

This paper derives a valuation model of inflation‐indexed convertible bonds that incorporates the firm's stock price, inflation indexing and the firm's credit risk. The pricing of inflation‐indexed convertible bonds traded on the Tel‐Aviv Stock Exchange (TASE) was empirically tested by using a comprehensive database. The study is the first to empirically test the pricing of convertibles in emerging markets. It was found that the theoretical values for the bonds are, on average, 1.94% higher than the observed market prices. Unlike previous studies, it was found that the underpricing increases with the moneyness of the convertible. It was found that as the maturity lengthens, the underpricing increases. © 2008 Wiley Periodicals, Inc. Jrl Fut Mark 28:634–655, 2008     

E-coli,Repo Madness,and the Financial Crisis

All bond prices plummeted (spreads rose) during the financial crisis, not just the prices of subprime-related bonds. These price declines were because of a banking panic in which institutional investors and firms refused to renew sale and repurchase agreements (repos)—short-term, collateralized, agreements that the U.S. Federal Reserve rightly used to count as money. Collateral for repos was, to a large extent, securitized bonds. Firms were forced to sell assets as a result of the banking panic, reducing all bond prices and creating losses. There is nothing mysterious or irrational about the panic. There were genuine fears about the locations of subprime risk concentrations among counterparties. This banking system (the “shadow” or “parallel” banking system)—repos based on securitization—is a genuine banking system, as large as the traditional, regulated banking system. It is of critical importance to the economy because it is the funding basis for the traditional banking system. Without it, traditional banks will not lend and credit will not be created.     

中国可转债发行的股权价值效应

本文运用Merton(1990)的或有索取权分析方法,对中国上市公司发行可转债行为对非流通股东和流通股东股权价值的不同影响作了深入的分析,得出如下结论:(1)在中国目前股权分割的情况下,无论可转债是否按照合理价格发行,原有流通股的价值都会减少;(2)在非流通股东占控股地位的情况下,它会选择折价发行并向全体股东配售这一对其最为有利而对流通股东最为不利的可转债发行方案。并在此基础上提出政策建议:修改可转债发行法规,规定可转债只能向原有流通股股东配售,不能向社会公众和非流通股股东配售。     

The impact of household level heterogeneity in reference price effects on optimal retailer pricing policies

The field of marketing has witnessed substantial improvement in modeling household level heterogeneity. However, relatively little has been written about how modeling household heterogeneity translates into better marketing decisions. In this paper, we study the impact of household level heterogeneity in reference price effects on a retailer's pricing policy. Reference prices are certain anchors or standards that households use to compare the observed purchase price of a product against. If the observed price is greater than the reference price it is perceived as a “loss” and if it is smaller than the reference price it is perceived as a “gain”. In order to study the impact of heterogeneity in reference price effects on retail pricing, we test a nested logit model under two alternative reference price (memory and stimulus based) and heterogeneity (finite mixture and hierarchical Bayes) specifications. In the empirical analysis, we find that households are quite heterogeneous in terms of their gain and loss effects. For some households a gain has higher impact than a corresponding loss, while the opposite is true for others. Using individual level estimates we then develop a normative pricing policy for a retailer maximizing category profit. Our results indicate that the optimal pricing policy derived from the heterogeneous case is qualitatively different, and more profitable, than the case when heterogeneity is ignored. We show that for an important marketing problem pertaining to a retailer, the optimal pricing decisions for various brands in a category are inextricably related to household heterogeneity in reference effects and brand preference.
