Dilution of Earnings per Share in an Option Pricing Framework.
重新审视每股收益计算中处理潜在稀释性证券的现行方法，利用期权和可转换证券的均衡定价模型，提出可预测自愿转换或行权时点的理论框架，并讨论政策含义。
Abstract ABSTRACT: The currently prescribed method of dealing with potentially dilutive securities in earnings per share calculations is reconsidered in light of the more recent development of equilibrium pricing models for options and convertible securities. This new treatment of an old problem offers a theoretical structure founded upon recent developments in finance. It is shown that fairly precise statements about the timing of voluntary conversion or exercise of potentially dilutive securities are often possible. Moreover, assessments of the probabilities of future stock prices reaching levels which would allow conversion or exercise can be derived from a widely used stochastic model of security price behavior. Some implications for policy are discussed.
