C.

Under the BGN mode.

An investor purchased an annuity many years ago. The first payment of the annuity is to be received today. 


老师看了您给其他学生的解答说是received today所以是0时刻，但是题目不是说很多年前就买了这个annuity，那么买的时候就应该是0时刻？然后今天才付钱，今天付钱的时刻不应该是1了吗？先买后付，不应该是ordinary annuity吗？

对的，这就是题目所表述的意思。

同学你好，

“... purchased an annuity many years ago”这句话没有用，无论年金是在什么时候买的，过去的已经过去了。年金的价值是未来的现金流折现求和。

换而言之，年金的现值求的就是“today”的值，而不是“many years ago”的值。

对于未来的现金流来说，首笔就是在今天付的，所以就是先付年金的形式。如果首笔是在一年后 / at the end of the first year时付的，就是后付年金。

老师，你的意思是，这个年金是在过去买的，但是是从今天开始支付首笔款，连续支付20年，求现值？
