Yield to maturity (YTM) is the rate of return expected from a bond held until its maturity date. However, the YTM equals the expected rate of return under certain assumptions. Which of the following is one of those assumptions? The bond is callable. The probability of default is zero. Consider the case of Demed Inc.: Demed Inc. has 9% annual coupon bonds that are callable and have 18 years left until maturity. The bonds have a par value of $1,000, and their current market price is $1,100.35. However, Demed Inc. may call the bonds in eight years at a call price of $1,060. What are the YTM and the yield to call (YTC) on Demed Inc.'s bonds? Value YTM YTC If interest rates are expected to remain constant, what is the best estimate of the remaining life left for Demed Inc.'s bonds? O 8 years O 13 years O 18 years O 10 years If Demed Inc. issued new bonds today, what coupon rate must the bonds have to be issued at par
