An estimated regression equation was developed to predict the average number of runs given up per inning pitched (R/IP) given the average number of strikeouts per inning pitched (SO/IP) and the average number of home runs per inning pitched (HR/IP).

R/IP = 0.5365 - 0.2483 SO/IP + 1.032 HR/IP

Problem 7-8
Yield to call

Seven years ago the Singleton Company issued 26-year bonds with a 12% annual coupon rate at their $1,000 par value. The bonds had a 7% call premium, with 5 years of call protection. Today Singleton called the bonds.

a.Compute the realized rate of return for an investor who purchased the bonds when they were issued and held them until they were called. Round your answer to two decimal places.

b.Explain why the investor should or should not be happy that Singleton called them. (select multiple choice answer)

-Since the bonds have been called, interest rates must have risen sufficiently such that the YTC is greater than the YTM. If investors wish to reinvest their interest receipts, they can now do so at higher interest rates.

-Since the bonds have been called, interest rates must have risen sufficiently such that the YTC is greater than the YTM. If investors wish to reinvest their interest receipts, they must do so at lower interest rates.

-Since the bonds have been called, investors will receive a call premium and can declare a capital gain on their tax returns.

-Since the bonds have been called, investors will no longer need to consider reinvestment rate risk.

-Since the bonds have been called, interest rates must have fallen sufficiently such that the YTC is less than the YTM. If investors wish to reinvest their interest receipts, they must do so at lower interest rates.
