Duration of the Bond | ||
a. | $10,000 par value, coupon rate = 8.4%, rb = 0.14 | years |
b. | $10,000 par value, coupon rate = 10.4%, rb = 0.14 | |
c. | $10,000 par value, coupon rate = 12.4%, rb = 0.14 | |
Par value = $10,000
Maturity = 5 years (Annual payments)
R = 14%
a). Coupon Rate = 8.4%
Time(t) | CF | PV of CF | PV of CF x t |
1 | $840 | $ 736.84 | $ 736.84 |
2 | $840 | $ 646.35 | $1,292.71 |
3 | $840 | $ 566.98 | $1,700.93 |

5 | $840 | $ 436.27 | $2,181.35 |
Total | $2,883.79 | $7,901.21 |
Duration = $7,901.21/$2,883.79 = 2.74 years
b). Coupon Rate = 10.4%
