Original variant: recover the liability supported by a bond ladder
A ladder holds a one-year 2% coupon bond with face 452.85, a two-year 5% coupon bond with face 761.90, and a three-year zero with face 1,000. Coupons are annual. If years two and three are exactly matched, what year-one liability does the ladder support?
- A
450.00 - B
475.00 - C
500.00 - D
525.00 - E
550.00
Answer and calculation
Year one receives 1.02(452.85) plus 5% of 761.90, totaling 500.00, choice C.
Setup
Setup
At year one, the first bond pays coupon plus redemption while the second bond pays its first coupon.
C1=1.02(452.85)+0.05(761.90) Model
Model
The three-year zero contributes nothing before year three.
C1=461.907+38.095 Compute
Compute
Adding the two available year-one cash flows gives 500.002, with the difference caused by quoted face-value rounding.
C1=500.002 Answer
Answer
The ladder supports a year-one liability of 500.00, corresponding to choice C.
C1≈500.00(C)
