This Exam FM sample reference tests Cash-Flow and Risk Matching. Strategy I reproduces both liability amounts at their exact dates; II only matches current value under a rate that may change, and III is Redington immunization rather than exact matching, so choice A.
How to solve this Cash-Flow and Risk Matching question
Setup
Setup
Exact matching requires each asset payment to equal the corresponding liability on the same date.
CFI,1=1000,CFI,2=1000
Model
Model
The two zeros in strategy I do exactly that.
PVII=PVL⟹CFII,t=CFL,t
Compute
Compute
A deposit subject to repricing after one year does not lock both payments, while matching duration and convexity is an immunization strategy rather than cash-flow identity.
PVIII=PVL,DIII=DL,CIII>CL
Answer
Answer
Only strategy I qualifies, which is choice A.
I only(A)

The searchable 2210-page manual includes this complete solution, its error analysis, and one original worked variant for every active reference.
These notes identify the calculation error associated with each wrong letter when that error is reproducible.
BStrategy II depends on a future reinvestment rate and does not lock both liability payments.
CStrategy III states Redington conditions, not equality of every dated cash flow.
DIncluding II and III ignores the distinction between exact matching and summary risk matching.
EStrategy I is an explicit exact match, so the catch-all option cannot be correct.

Original variant: identifying exact funding for a two-stage restoration
A restoration project owes 700 after one year and 900 after three years. Plan R buys zeros maturing for exactly those amounts on those dates. Plan S buys one security with equal present value and duration but different payment dates. Which plan is guaranteed to be an exact match?
A R only
B S only
C Both R and S
D Neither
E Only if rates are flat
Variant answer in brief
R reproduces both dated obligations; value and duration do not force S's cash-flow vector, so choice A.
Setup
Setup
Write exact matching as equality of the full dated cash-flow vector.
CFR=(700 at 1,900 at 3)=CFL
Model

Plan R meets that definition directly at both liability dates.
PVS=PVL,DS=DL

Plan S matches two summary measures, but many distinct cash-flow streams share those measures.
(PV,D) equality⟹CFS=CFL
Answer
Answer
Only R is guaranteed exact, so choice A is correct.
