Original variant: recover a bond coupon from price
A bond redeems for 1,100 and pays level annual coupons. Its annual effective yield is 6%. The present value of redemption is 550, and the total bond price is 1,050. Determine the annual coupon.
- A
40 - B
50 - C
60 - D
70 - E
80
Answer and calculation
Redemption has discount factor 0.5, making the coupon annuity factor 8.3333; the 500 coupon value therefore requires coupon 60, choice C.
Setup
Setup
Use the redemption present value to identify the discount factor through maturity.
550=1100vn⟹vn=0.5 Model
Model
Convert that factor into the present-value factor for the annual coupon annuity.
an∣0.06=0.061−0.5=8.333333 Compute
Compute
Coupons account for 500 of the price, so dividing by 8.333333 gives 60.
C=8.3333331050−550=60 Answer
Answer
The annual coupon is 60, corresponding to choice C.
C=60(C)
