Original variant: present cost of a two-date sculpture fund
A sculpture fund must deliver 2,500 after one year and 4,000 after three years. One-year zeros yield 4% and three-year zeros yield 6%, both effective annually. Calculate the current cost of exact cash-flow matching.
- A
5,500.00 - B
5,650.00 - C
5,762.32 - D
5,900.00 - E
6,100.00
Answer and calculation
Discounting each liability at its matching zero yield gives total cost 5,762.32, choice C.
Setup
Setup
Each zero-coupon holding can be selected to mature for exactly one required delivery.
C1=2500/1.04=2403.846 Model
Model
Apply the one-year yield only to the first amount and the three-year yield over all three years to the second.
C3=4000/1.063=3358.477 Compute
Compute
The two current costs are 2,403.846 and 3,358.477.
C=C1+C3=5762.323 Answer
Answer
Their sum is 5,762.32, which is choice C.
C=5762.32(C)
