This Exam FM sample reference tests Immunization and Asset-Liability Management. Exact cash-flow matching requires investing 925.93 for the year-1 liability and 751.31 for the year-3 liability. Their difference is 174.61, so choice E is correct.
These notes identify the calculation error associated with each wrong letter when that error is reproducible.
AChoice A (0) does not satisfy the separate present values of the year-1 and year-3 matched liabilities; no distinct standard one-step error is identifiable.
BChoice B (84) does not satisfy the separate present values of the year-1 and year-3 matched liabilities; no distinct standard one-step error is identifiable.
CChoice C (132) does not satisfy the separate present values of the year-1 and year-3 matched liabilities; no distinct standard one-step error is identifiable.
DChoice D (158) does not satisfy the separate present values of the year-1 and year-3 matched liabilities; no distinct standard one-step error is identifiable.

Original variant: budget for an exact two-date cash-flow match
A scholarship plan must pay 800 at the end of year 1 and 1,200 at the end of year 3. One- and three-year zero-coupon securities yield 4% and 6% annually. Calculate the total amount that must be invested today to match both payments exactly.
A 1,599.10
B 1,687.94
C 1,776.77
D 1,865.61
E 1,954.45
Variant answer in brief
The two matching investments are 769.23 and 1,007.54. Their total present cost is 1,776.77, choice C.
Setup
Setup
Assign each liability to the zero-coupon security with the same maturity.
I1=800(1.04)−1
I3=1200(1.06)−3
Model
Model
Because the cash flows are exactly matched, the required budget is the sum of the two present investments.
B=I1+I3
Compute
