限制性股票这种激励模式已经成为我国上市公司股权激励的主要方式,会计准则规定,权益性股份支付需要在等待期内的每个资产负债表日按“权益工具授予日的公允价值乘以估计的行权数量”摊销激励费用。权益工具授予日公允价值既影响激励费... 限制性股票这种激励模式已经成为我国上市公司股权激励的主要方式,会计准则规定,权益性股份支付需要在等待期内的每个资产负债表日按“权益工具授予日的公允价值乘以估计的行权数量”摊销激励费用。权益工具授予日公允价值既影响激励费用的摊销金额,也影响激励指标达成与否,管理层存在低估公允价值以提高公司业绩的可能性。对于限制性股票,以内在价值为基础确定的公允价值一般会大于以期权估值模型为基础确定的公允价值。本文研究发现,上市公司限制性股票权益工具公允价值大都采用以期权估值模型为基础的方法,存在低估公允价值进行业绩管理的现象。 展开更多

This analysis includes a carbon sequestration structure cost and possible revenues from carbon credit markets. The evaluation focuses on the determination of an optimal timing for the investment in different scenarios, regarding the volatility of the uncertain variable, oil prices. Historical prices data from different moments are used to estimate different prices uncertainty scenarios and its impacts on the decision making on building a carbon sequestration structure. The results are compared between a real option model to the ones obtained using the traditional net present value evaluation. Trigger point of investments are defined for different scenarios with and without carbon sequestration. There is also an analysis of the effects on decision-making in different scenarios for carbon market prices. It is perceived an important difference in the decision making considering the different methods of economic analysis. The real option model is a fundamental valuation tool in periods of high price volatility and higher sunk costs added to a project such as the carbon sequestration structure. Greenhouse gas projects demand high oil prices, positive market trend expectation and volatility. 展开更多
