摘　　要：基于证券投资者的投资需要,借助于数理统计方法发展起来的期权定价模型,无法避免主观估计的影响,所确定的估价金额与会计计量中的公允价值在内在要求上存在一定差距。公允价值的基本特征可概括为"公允性"、"现时性"和"估计性",从中可得出结论:期权的公允价值应该只包括相当于其内在价值的部分,对于因期权标的物未来价值不确定所带来的风险价值部分,可通过报表附注的形式予以充分披露。The options pricing model developed according to mathematics statistic method and based on the needs of investor would be inevitably affected by subjective factor. The price acquired in this model does not agree with the fair value of accounting measurement in inwardness. The fair value has three elementary characteris- tics ： fairness, presentness and estimation through which we can draw the conclusion that the option＇ s fair value ought to contain its intrinsic value only. The option＇ s risk value coming from value uncertainty of its corpore could be fully disclosed by the annotations of statement.
