求助啊，为什么我老是会判断错时间呢，它上面写着5年，我就按照5年折现，可是答案却是4年，我要怎么分清楚问题中到底多少年这种呢，已经在这种题栽倒了无数次了，问题如下图：
选项：
A. 
B. 
C.

同学您好，这道题的意思是，有一个按季度付息的优先股从第五个季度开始以永续年金的形式按季付息，每个季度支付的利息为$2.00。按照永续年金的公式PV=A/r，已知A=2，r=6%/4（6%为年利率），可得PV4=$133.33（这个求得的PV实际上是第四个季度末的PV），所以我们想要求这个stock现在的价值，就要把这个PV4进行折现。根据折现公式
，这里的FV就是刚刚所求得的PV4，
对于这种类型的题目，画图其实是最好的办法。不是说题目写着五就是按照五来计算的意思。同学你可以再去听一听基础班何老师讲解的关于货币时间价值的一些例题，多画画图，应该可以帮助你更好地理解。因为你可以很清晰直观的看到这些payment是折现到哪一年等信息。加油哦~
NO.PZ2017092702000009 问题如下 A perpetupreferrestomakes its first quarterly vinpayment of $2.00 in five quarters. If the requireannurate of return is 6% compounquarterly, the stock’s present value is closest to: A.$31. B.$126. C.$133. B is correct. The value of the perpetuity one yefrom now is calculateas: PV = A/r, where PV is present value, A is annuity, anr is expressea quarterly requirerate of return because the payments are quarterly. PV = $2.00/(0.06/4) PV = $133.33. The value toy is (where FV is future value) PV = FV(1 + r)–NPV = $133.33(1 + 0.015)–4 PV = $125.62 ≈ $126 /sp12 /sp\frac12 /sp21 请问这个两阶段模型，第一阶段是后续永续增长的利息折现到t=5，然后用P5再向前折现对吗？P5向前折现为什么不是5次方呢？
