同學(xué),上午好。
此題思路是計(jì)算exhibit 1 中的dollar duration,然后和liability的dollar duration計(jì)算??词欠衿ヅ?br/>
然后exhibit 1 需要作以下調(diào)整:
1. treasury bonds Strips會新增加 500m(make a $500 million contribution to fully fund the plan and invest the funds in Treasury STRIPs)
2. 題干中說,reallocate pension investments away from the fund that presents the greatest contingent claim risk and into the long corporate bond fund,其中有 greatest contingent claim risk的是MBS,所以將MBS中的700,000要調(diào)整到long corporate bond fund中。
然后,根據(jù)這兩個信息,重新計(jì)算exhibit 1 中的dollar duration,然后和liability的dollar duration計(jì)算。看是否匹配。

所以最后是用Dollar Duration ($ thousands)和500m比較嗎?

追答
對的,同學(xué),你的理解是正確的。但是liability的dollar duration是4 billion×14=56000million
-
追問
4 billion和14是怎么來的?我看解析是在每一項(xiàng)用New Market Value ($ thousands)乘以Duration (years)得出Dollar Duration ($ thousands)。然后再把Dollar Duration ($ thousands)加總的結(jié)果和500million比較,然后兩個數(shù)字差不多。

追答
4billion和14是題干給的條件 (the pension liability has a duration of 14 years and a present value of $4 billion)
解析是加總得到55,998,750,然后和56,000,000比較,兩個數(shù)字差不多。
