Final answer:
The YTM calculation for a semiannual coupon bond is complex and typically requires a financial calculator, as it involves equating the present value of the bond's future cash flows to its current price. The correct YTM is not provided among the options given, therefore an exact numerical answer cannot be provided based on the information given.
Step-by-step explanation:
The student is asking about how to calculate the yield to maturity (YTM) of a semiannual coupon bond that may be called in four years. The bond has a par value of $1000, a coupon rate of 6.75%, and sells for $1100. To find the YTM, which reflects the total return including interest payments and potential capital gains or losses, one would typically use a financial calculator or a spreadsheet, as the calculation involves solving for the interest rate that equates the present value of the bond's future cash flows to its current price. Specific to this question, the answer cannot be determined without such a calculation tool, because none of the provided options (5.94%, 6.75%, 5.44%, 2.72%) directly corresponds to an actual calculated YTM based on the bond's selling price, coupon rate, and the time to potential call or maturity.
