A friend of yours purchased $50,000 (face value) of Sortinu Corporation bonds for $62, 500 on March 1, 2014. The bonds were issued on September 1, 2006, have a 6% annual coupon rate, and pay interest semiannually on February 28 and August 31. It is now March 23, 2017, and your friend has received all of the coupon payments since she acquired the bonds. The bonds mature on August 31, 2031. Required: Answer the following questions concerning this investment. What is the amount of the coupon payments that your friend received on August 31, 2014, February 28, 2015, August 31, 2015, February 28, 2016, August 31, 2016, and February 28, 20177? What was the Yield-to-Maturity your friend expected when she purchased the bonds in 2014? The yield-to-maturity is effectively the internal rate of return if she holds the bonds until they mature and collects all of the promised coupon payments and the maturity value when the bond matures. Assume that the market interest rate for similar bonds was 8%, compounded semiannually, on February 28, 2017. At what price would those bonds have been selling at that time? If your friend had sold the bonds on February 28, 2017, at the price you determined in part 3, what annual rate of return (APR) would she have earned over her three-year holding period? (Regardless of whether she sells the bonds or not, this is called the holding-period return. It is an unrealized return if she doesn't sell them and a realized return if she sells them.)
