为什么这道题选低利率

NO.PZ2020011901000034

问题如下:

A company’s defined benefit plan invests primarily in equities. Which of the following creates risks for the company? (Assume that equity markets are unaffected by A, B, C, and D.)

选项:

A.

High interest rates

B.

Low interest rates

C.

Employees working past retirement age

D.

An epidemic that shortens life expectancy

解释:

B. Low interest rates will reduce the discount rate used to assess liabilities and therefore increase the present value of the liabilities. High interest rates, employees working past retirement age, and a shortening of life expectancy all lessen risks. (The question states that the impact of A, B, C, and D on equity markets should not be considered. In practice a reduction in interest rates tends to lead to an increase in equity prices.)

公司的DB plan是给员工退休后固定的养老金,相当于一个债券性质的负债。

为了满足这个负债,公司却投资的全是股票。那此时利率下降时债券的PV变大,买的股票不一定能cover这些负债。
