问一道题：NO.PZ2015120604000013 [ CFA I ]

  1. CFA I
  2. Quantitative

问题如下图：

    

选项：

A.

B.

C.

解释：


答案解析中的第一步为什么说PMT可以是2000；第二步，为什么PMT是0，不是2000呢？我的理解是，前面12年每年存2000，后面20年再每年取钱，直到把这12个2000的pv全部取出来。

题目的意思是有一个20年期的年金，在第十三年末收到第一笔PMT。

所以第一步是先算出这笔年金在十二年末的价值。然后第二步再折现到现在t=0时刻。

是不是相当于0-12年末什么事情都没发生？t=13至t=33是每年年末得到一笔2000PMT
