Answer:
Value of bond = Present value of coupon payments + Present value of maturity or par value
Present value of coupon payments:
Coupon is semi annual = 275,000 * 10% * 1/2
= $13,750
Interest = 9%/ 2 = 4.5%
Duration = 5 * 2 = 10 semi annual periods
Present value will be that of an annuity as this cash flow is fixed:
= 13,750 * (1 - (1 + 4.5%)⁻¹⁰) / 4.5%
= $108,799.87
Present value of par value:
= 275,000 / ( 1 + 4.5%)¹⁰
= 177,080.11
Value of bond:
= 108,799.87 + 177,080.11
= $285,879.98
= $285,880
Proven.
