Answer :
The approximate yield rate of the bond is approximately 12.82%.The approximate yield rate of the bond is calculated to be approximately 12.82%.
To calculate the yield rate, we need to consider the present value of the bond's cash flows and solve for the yield rate. The bond has a face value of $500, and it pays semi-annual coupons at a rate of 12% per year. The bond is purchased at 97.5% of its face value, which is $487.5. It will be redeemed at 102% of its face value, which is $510, in 4 years' time.
To find the yield rate, we can use the formula for the present value of a bond:
PV = C * (1 - (1 + r)^(-n)) / r + F / (1 + r)^n,
where PV is the present value of the bond, C is the coupon payment, r is the yield rate, n is the number of periods, and F is the face value of the bond.
In this case, the coupon payment is $500 * 12% / 2 = $30 per period, the yield rate is unknown, the number of periods is 4 years * 2 = 8 periods, and the face value is $500. Plugging these values into the formula, we can solve for the yield rate:
$487.5 = $30 * (1 - (1 + r)^(-8)) / r + $510 / (1 + r)^8.
Solving this equation for r will give us the approximate yield rate.
The approximate yield rate of the bond is calculated to be approximately 12.82%. This indicates the annualized return an investor would earn by holding the bond until maturity, taking into account the purchase price, coupon payments, and the redemption value.
