NO.PZ2016031201000043 相当于不用考虑时间价值，这样理解对么
NO.PZ2016031201000043 present value of the exercise priminus the value of the unrlying. value of the unrlying minus the present value of the exercise price. B is correct. Prior to expiration, the lowest value of a Europeput is the greater of zero or the present value of the exercise priminus the value of the unrlying.请问最低价格是因为不考虑到期日之前的时间价值吗
