Original variant: determine an intermediate bond face
Liabilities of 3,000, 5,000, and 8,000 fall due at years 1, 2, and 3. They are exactly matched with annual coupon bonds maturing at years 1, 2, and 3, carrying coupon rates 2%, 4%, and 6% respectively. Each bond redeems at par. Find the face amount of the two-year bond.
- A
3,940.11 - B
4,180.56 - C
4,372.28 - D
4,615.38 - E
4,807.69
Answer and calculation
The three-year bond face is 7547.17 from the last liability. Removing its year-2 coupon leaves a two-year bond face of 4372.28, choice C.
Setup
Setup
Back-solve the three-year face C from its maturity cash flow.
1.06C=8,000 C=7,547.1698 Model
Model
At year 2, the two-year maturity and the three-year coupon must total 5000.
1.04B+0.06C=5,000 Compute
Compute
Solve for the requested face amount.
B=1.045,000−0.06(7,547.1698)=4,372.2787 Answer
Answer
The two-year bond face is 4372.28, choice C.
