Generally, it is presumed that an interest rate swap hedge of fixed income assets and liabilities will be 100% effective. Specifically, SFAS-133.68 actualizes this effectiveness through its short-cut method (SCM) interest rate risk hedge specification. We show that this presumption is false. This negative finding leads to a severe IAS-39 implementation problem because IAS-39 explicitly precludes the SCM. Furthermore, this problem has major implications for bank (and insurance) capital requirements. We specify a series of remedies for this problem. We believe that the best remedy falls in the fine print of IAS-39.F.5.5 guidance. In this guidance, a "theoretical swap" hedge effectiveness method, (B), effectively, provides FAS-133 SCM treatment for analogous IAS-39 interest rate risk hedges.
一般假设固定收益资产和负债的利率互换对冲是100%有效的。具体而言,sfas133.68通过其利率风险对冲的捷径方法(SCM)规范实现了这一有效性。我们证明这种假设是错误的。这一负面发现导致了严重的IAS-39实施问题,因为IAS-39明确排除了SCM。此外,这个问题对银行(和保险)的资本要求有重大影响。我们针对这个问题提出了一系列补救措施。我们认为,最好的补救办法是IAS-39.F.5.5指导的细则。在本指南中,“理论互换”套期保值有效性方法(B)有效地为类似的IAS-39利率风险套期保值提供了fas133 SCM处理。

This paper analyzes the current state of non-executive employee stock option (ESO) issuance in Japan. First, I find that the main determinant of ESO issuance for individual firms is the extent of their corporate flexibility, although other hypotheses may be applicable depending on the industrial sector; second, the impact on the macro-economy is still quite small at the aggregate level. However, taking account of the fair cost of issuing ESOs could have a substantial effect on the profits of individual firms. Furthermore, I find that issuing ESOs tends to have a somewhat negative effect on stock prices.
本文分析了日本非执行董事员工股票期权发行的现状。首先,我发现个别公司发行ESO的主要决定因素是其公司灵活性的程度,尽管根据工业部门,其他假设可能适用;第二,从总量上看,对宏观经济的影响还很小。然而,考虑到发行股票的公平成本可能会对个别公司的利润产生重大影响。此外,我发现发行eso往往对股价有一定的负面影响。

Preparing for the imminent arrival of International Financial Reporting Standards (IFRS) is proving to be challenging for many European companies for which IFRS takes effect in 2005. Not least among these challenges are that reporting requirements are substantial and time to prepare is running short. Transition to the new standards will bring further demands as market participants familiarize themselves with the revised financial reporting. Specifically, companies will need to pay particular attention to how they communicate their financial restatements. If market participants are not provided with clear information, the capital markets could face potential disruption if investors and analysts adopt overly conservative positions until greater clarity is obtained.
事实证明,为即将到来的国际财务报告准则(IFRS)做准备对许多将于2005年生效的欧洲公司来说是一项挑战。在这些挑战中,最重要的是报告要求非常多,准备时间越来越短。随着市场参与者熟悉修订后的财务报告,向新准则的过渡将带来进一步的要求。具体来说,公司需要特别注意他们如何传达他们的财务重述。如果市场参与者没有获得明确的信息,在获得更明确的信息之前,如果投资者和分析师采取过于保守的立场,资本市场可能面临潜在的混乱。

Operating Leverage and the Interaction between Abandonment Options and Exotic Hedging 经营杠杆与放弃期权与异域套期保值的相互作用
Pub Date : 2005-03-01 DOI: 10.1142/S0219868105000331

This paper examines the interaction between operational and financial hedging in the context of the competitive firm under output price uncertainty. The firm is endowed with an abandonment option in that its production decision is made after the true realization of the random output price has been observed. If the realized output price is less than its marginal cost, the firm optimally exercises its abandonment option and ceases from production. Otherwise, the firm lets its abandonment option extinguish and produces at its capacity. The existence of the abandonment option is shown to induce the firm to opt for a concave payoff risk-sharing rule that can be perfectly replicated by writing call options with a single strike price set equal to the marginal cost. We derive necessary and sufficient conditions that ensure a positive (negative) effect of operational hedging via the abandonment option on the firm's optimal operating leverage. In contrast, we show that the effect of financial hedging via customized exotic derivatives on the firm's optimal operating leverage is unambiguously positive. These results suggest that the interaction between abandonment options and exotic hedging is multi-dimensional and deserves further scrutiny.
本文研究了在产出价格不确定的竞争企业背景下,操作和财务套期保值之间的相互作用。由于企业的生产决策是在观察到随机产出价格真正实现之后做出的,因此企业被赋予了放弃选项。如果实现的产出价格小于边际成本,企业最优地行使放弃选择权并停止生产。否则,企业让其放弃选择权消失,并以其产能生产。放弃期权的存在诱使企业选择凹支付风险分担规则,该规则可以通过编写单一执行价格等于边际成本的看涨期权来完美复制。我们推导了通过放弃期权对公司最优经营杠杆进行操作套期保值的正(负)效应的充分必要条件。相反,我们表明,通过定制的外来衍生品进行金融对冲对公司的最优经营杠杆的影响是明确的积极的。这些结果表明,放弃期权与外来套期保值之间的相互作用是多维的,值得进一步研究。

EVALUATION OF HEDGE EFFECTIVENESS TESTS 套期保值有效性测试的评价
Pub Date : 2005-03-01 DOI: 10.1142/S021986810500029X
Angelika C. Hailer, S. Rump
According to IAS 39 or FAS 133 an a posteriori test for hedge effectiveness has to be implemented when using hedge accounting. Both standards do not regulate which numerical method has to be used. A number of hedge effectiveness tests have been published recently. Such tests are of different quality; for example, not all of them can deal with the problem of small numbers. This means a test might determine an effective hedge to be ineffective, a scenario which would increase the volatility in earnings. Therefore, it seems useful to have criteria at hand to discriminate and assess hedge effectiveness tests. In this paper, we introduce such objective criteria, which we develop according to our understanding of miminum economic requirements. They are applicable to tests based on market values of two points in time as well as tests based on time series of market values. According to our criteria we compare common tests like the dollar offset ratio, regression analysis or volatility reduction, showing strengths and weaknesses. Finally, we develop a new Adjusted Hedge Interval test based on our previous one (Hailer, AC and SM Rump (2003). Zeitschrift fur das gesamte kreditwesen, 56(11), 599–603). Our test does not show weaknesses of other effectiveness tests.
根据IAS 39或FAS 133,在使用套期会计时必须实施套期有效性的后验检验。这两个标准都没有规定必须使用哪种数值方法。最近发表了许多对冲有效性测试。这些测试的质量各不相同;例如,不是所有的人都能处理小数字的问题。这意味着测试可能会确定有效的对冲无效,这种情况将增加收益的波动性。因此,手头有标准来区分和评估套期有效性测试似乎是有用的。在本文中,我们介绍了这些客观标准,这些标准是我们根据对最低经济要求的理解制定的。它们既适用于基于两个时间点的市场价值的测试,也适用于基于市场价值时间序列的测试。根据我们的标准,我们比较常见的测试,如美元抵消率,回归分析或波动性减少,显示优势和劣势。最后,我们在之前的测试(Hailer, AC和SM Rump(2003))的基础上开发了一个新的调整对冲区间测试。科学通报,26(1),393 - 393。我们的测试没有显示出其他有效性测试的弱点。

PRICING S&P 500 INDEX OPTIONS UNDER STOCHASTIC VOLATILITY WITH THE INDIRECT INFERENCE METHOD 随机波动下标准普尔500指数期权的间接推理定价方法

This paper studies the price of SP in the second step, the risk premium, λ, the spot variance, vt, and the correlation coefficient between the asset return and its volatility, ρ, are estimated by a nonlinear least-squares method that minimizes the sum of the squares of the error between the cross-sectional option price and the corresponding model price. The model performance is assessed by directly comparing the computed option model price with the market price. We find that both the Black–Scholes model and the Heston model overprice the out-of-the-money options and underprice the in-the-money options, but the degree of the bias is different. The Heston model significantly outperforms the Black–Scholes model in almost all moneyness-maturity groups. On average, the Heston model can reduce pricing errors by about 25%. However, pricing bias still exists in the Heston model. In particular, the Heston model always overprices short-term options, indicating that some other factors, such as the random jump, may also be needed to explain the option price.
本文在第二步中研究了SP的价格,采用非线性最小二乘法估计风险溢价λ、现货方差vt和资产收益与波动率的相关系数ρ,该方法使横截面期权价格与相应模型价格的误差平方和最小。通过直接比较计算出的期权模型价格与市场价格来评估模型的性能。我们发现,Black-Scholes模型和Heston模型都对价外期权定价过高,对价内期权定价过低,但偏差程度不同。赫斯顿模型在几乎所有的货币成熟度组中都明显优于布莱克-斯科尔斯模型。平均而言,赫斯顿模型可以减少约25%的定价误差。然而,赫斯顿模型中仍然存在定价偏差。特别是,赫斯顿模型总是高估短期期权,这表明可能还需要一些其他因素,如随机跳变,来解释期权价格。

VALUING AND HEDGING AMERICAN OPTIONS UNDER TIME-VARYING VOLATILITY 时变波动下的美国期权估值与对冲
Pub Date : 2004-09-01 DOI: 10.1142/S0219868104000191

There has been considerable interest in developing stochastic volatility and jump-diffusion option pricing models, e.g. Hull and White (1987, Journal of Finance, 42, 281–300) and Merton (1976, Journal of Financial Economics, 3, 125–144). These models, however, have some undesirable aspects that arise from introducing some non-traded sources of risks to the models. Furthermore, the models require much analytical complications; thus, if they are applied to American options then it is not easy to acquire practical implications for hedging and optimal exercise strategies. This paper examines the American option prices and optimal exercise strategies where the volatility of the underlying asset changes over time in a deterministic way. The paper considers two simple cases: monotonically increasing and decreasing volatilities. The discussion of these two simple cases gives useful implications for the possibility of early-exercise and optimal exercise strategies.
人们对开发随机波动率和跳跃扩散期权定价模型非常感兴趣,例如Hull和White (1987, Journal of Finance, 42, 281-300)和Merton (1976, Journal of Financial Economics, 3, 125-144)。然而,这些模型有一些不受欢迎的方面,这些方面是由于向模型引入了一些非交易的风险来源而产生的。此外,这些模型需要大量的分析复杂性;因此,如果将它们应用于美式期权,那么就不容易获得对冲和最优行使策略的实际含义。本文研究了标的资产波动率随时间以确定性方式变化的美式期权价格和最优行权策略。本文考虑两种简单的情况:单调增加和减少波动率。这两个简单案例的讨论为早期运动和最佳运动策略的可能性提供了有益的启示。

This study estimates the survival time distribution of the global macro class of hedge funds. We use methods of survival analysis to investigate how performance and nonperformance features of hedge funds could affect their lifetimes. We find that the effect of monthly returns and average assets under management is significant and has an impact on survival. We further discover that between 6 and 8 years of existence there is a sharp increase in the hazard of failure, which is most likely attributed to the Russian Ruble crisis of August 1998. The assumption by the media that many global macro hedge funds have been accused of failing due to their excessive leverage may in fact be wrong.
本研究估计了全球宏观类对冲基金的生存时间分布。我们使用生存分析的方法来研究对冲基金的业绩和不业绩特征如何影响它们的寿命。我们发现月收益和平均管理资产的影响是显著的,并且对生存有影响。我们进一步发现,在6至8年的存在期间,失败的危险急剧增加,这很可能归因于1998年8月的俄罗斯卢布危机。媒体认为,许多全球宏观对冲基金之所以失败,是因为它们的杠杆率过高,这一假设实际上可能是错误的。

DOES ALLOWING ALTERNATIVE HEDGE DESIGNATIONS AFFECT FINANCIAL STATEMENT COMPARABILITY 允许其他套期名称是否会影响财务报表的可比性
Pub Date : 2004-09-01 DOI: 10.1142/S0219868104000142

The comparability of hedge accounting disclosures between companies increases the informational value of financial statements. In order to eliminate inconsistency in the reporting of hedging activities, the FASB issued SFAS No. 133, which was intended to provide comprehensive guidance for all derivatives reporting and disclosure. The fact that SFAS No. 133 allows some hedging transactions to be designated as either a fair value hedge or a cash flow hedge might suggest a lack of comparability for similar transactions. This paper identified several of these transactions and provides the comparative accounting. Even though fair value and cash flow hedges are accounted for differently, there was little difference in their net effect on reported earnings while other comprehensive income did fluctuate somewhat for cash flow hedges.
公司间套期会计披露的可比性增加了财务报表的信息价值。为了消除套期活动报告中的不一致性,美国财务会计准则第133号发布,旨在为所有衍生品报告和披露提供全面指导。SFAS第133号允许某些套期交易被指定为公允价值套期或现金流量套期,这一事实可能表明类似交易缺乏可比性。本文确定了其中的几个交易,并提供了比较会计。尽管公允价值和现金流套期保值的核算方式不同,但它们对报告收益的净影响几乎没有差异,而其他综合收益对现金流套期保值的影响确实有所波动。

This paper investigates the effects of SFAS 133 on earnings volatility, earnings predictability, and equity volatility in bank holding companies (BHCs). In contrast to large BHCs' assertion prior to the adoption of SFAS 133, the three income-affecting portions (i.e. hedge ineffectiveness gains/losses, gains/losses excluded in the assessment of effectiveness, and effects from canceled forecasted transactions once designated as cash flow hedge) did not increase earnings volatility in the top 30 BHCs for the first 12 quarters after adoption. Also, the three income-affecting portions did not deteriorate analysts' forecast performance. In addition, there is no evidence that volatility of stockholders' equity significantly increases due to SFAS 133. Further investigation of notes to financial statements reveals that some BHCs adjusted their usage of derivatives prior to SFAS 133 to mitigate the impact of SFAS 133 on earnings volatility.
本文研究了《财务会计准则第133号》对银行控股公司盈余波动性、盈余可预测性和股票波动性的影响。与大型BHCs在采用SFAS 133之前的断言相反,在采用后的前12个季度,前30家BHCs的三个影响收入的部分(即对冲无效收益/损失,有效性评估中排除的收益/损失,以及被指定为现金流对冲的已取消预测交易的影响)并没有增加收益波动。此外,这三个影响收入的部分并没有降低分析师的预测业绩。此外,没有证据表明股东权益的波动性因SFAS 133而显著增加。对财务报表附注的进一步调查显示,一些bhc在SFAS 133之前调整了衍生品的使用,以减轻SFAS 133对收益波动的影响。
