Original variant: level-annuity price implied by one maturity-matched zero investment
A three-year level annuity is exactly cash-flow matched with one-, two-, and three-year zero-coupon bonds at 4%. The insurer invests 4,000 today in the three-year zero. Calculate the present value of the full annuity.
- A
12,486.40 - B
13,110.72 - C
13,735.04 - D
14,359.36 - E
14,983.68
Answer and calculation
The three-year zero grows to the common annuity payment 4,499.46. Multiplying that payment by the three-year annuity factor gives total annuity price 12,486.40, choice A.
Setup
Setup
Accumulate the three-year zero investment to its maturity; exact matching makes that maturity value the level payment.
