Swift Software has a bond selling for $1,090.56 which has a coupon rate of 5.10%. The bond has 15 years until maturity.

a) What is the yield-to-maturity (YTM) on the bond?

b) Why would you expect the actual return you earn to be different than this YTM?

c) If you were comparing this to a Swift Software bond that also had a coupon rate of 5.10%, but 20 years left until maturity, which would you expect to be more sensitive to changes in interest rates?
