This Exam FM sample reference tests Cash-Flow and Risk Matching. Exact matching requires redemptions 4,000 and 6,000 in the one- and two-year zeros; discounting at their respective yields gives total current cost 8,573, choice B.
These notes identify the calculation error associated with each wrong letter when that error is reproducible.
AChoice A is inconsistent with the two independently discounted zero-coupon liabilities; no distinct standard single-step error producing it is identifiable.
CChoice C is inconsistent with the two independently discounted zero-coupon liabilities; no distinct standard single-step error producing it is identifiable.
DChoice D is inconsistent with the two independently discounted zero-coupon liabilities; no distinct standard single-step error producing it is identifiable.
EChoice E is inconsistent with the two independently discounted zero-coupon liabilities; no distinct standard single-step error producing it is identifiable.

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
Variant answer in brief
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.
