This Exam FM sample reference tests Exact Cash-Flow Matching with Coupon Bonds. The year-4 liability fixes Bond C face at 7300, and the year-3 liability then fixes Bond B face at 14200. Their year-2 coupons total 1221, giving choice A.
These notes identify the calculation error associated with each wrong letter when that error is reproducible.
BChoice B rounds the inferred face amounts before forming the year-2 coupon cash flow.
CChoice C includes a coupon from the one-year bond even though that bond has already matured.
DChoice D uses the year-3 liability itself as Bond B face instead of removing Bond C's coupon first.
EChoice E applies Bond B's 5% coupon rate to both remaining bond face amounts.

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
Variant answer in brief
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.
