Final answer:
The student's question pertains to finding the coupon rate of a bond given its selling price, yield to maturity, face value, and bond life. The coupon rate can be calculated by determining the annual coupon payments using the present value of annuities formula and then solving for the coupon payment amount.
Step-by-step explanation:
The student is asking how to calculate the coupon rate of a bond with a yield to maturity of 7.9%, a selling price of $1,006.27, a face value of $1,000, annual coupon payments, and a bond life of 9 years. To find the coupon rate, we need to determine the annual coupon payments that make the present value of the bond's cash flows equal to its current price.
The present value of annuities formula in financial mathematics is used to calculate these coupon payments. We use the yield to maturity as the discount rate for the present value calculations. The bond's current price is the sum of the present value of all future coupon payments and the present value of the face value repaid at maturity.
Let's assume the annual coupon payment is C, then the present value of the coupon payments PV(C) is calculated by:
PV(C) = C × [(1 - (1 + 0.079)⁻¹) / 0.079]
The present value of the face value PV(F) at maturity is calculated as:
PV(F) = $1,000 × (1 + 0.079)⁻¹
The equation becomes:
$1,006.27 = PV(C) + PV(F)
By solving this equation, we obtain the value of C, which can be then used to find the coupon rate by dividing C by the face value and multiplying by 100 to get a percentage.
