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。 这样解释应该可以理解一些？

老师，这道题真的很难看懂，很想问考试是否还会有类似的题目和表述？感觉再做一次还是会错。

我印象里考试中的题目的还是比较好理解的，不会有特别难读懂的情况。不过这道题相对来说表达还是可以理解的，你主要的疑问点应该是in five quarters，你理解为在五个季度中，但其实是从第五个季度开始的意思，这里表达的确实很容易让人误解。不过考试的时候应该不会有这种困扰哈。

同学你好，是的。
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？
