This Exam FM sample reference tests Immunization and Asset-Liability Management. The annuity price implies each liability payment is 4999.97. Exact immunization with one- and two-year zeros places the discounted second payment in the two-year bond, requiring 4535.12 today; choice B.
These notes identify the calculation error associated with each wrong letter when that error is reproducible.
AChoice A (3769) does not satisfy the present value of the second annuity payment in its maturity-matched zero; no distinct standard one-step error is identifiable.
CChoice C (4762) does not satisfy the present value of the second annuity payment in its maturity-matched zero; no distinct standard one-step error is identifiable.
DChoice D (5000) does not satisfy the present value of the second annuity payment in its maturity-matched zero; no distinct standard one-step error is identifiable.
EChoice E (9297) does not satisfy the present value of the second annuity payment in its maturity-matched zero; no distinct standard one-step error is identifiable.

Original variant: level-annuity price implied by one maturity-matched zero investment
A three-year level annuity is exactly cash-flow matched with one-, two-, and three-year zero-coupon bonds at 4%. The insurer invests 4,000 today in the three-year zero. Calculate the present value of the full annuity.
A 12,486.40
B 13,110.72
C 13,735.04
D 14,359.36
E 14,983.68
Variant answer in brief
The three-year zero grows to the common annuity payment 4,499.46. Multiplying that payment by the three-year annuity factor gives total annuity price 12,486.40, choice A.
Setup
Setup
Accumulate the three-year zero investment to its maturity; exact matching makes that maturity value the level payment.
P=4000(1.04)3
Model
