Bond value and timeChanging required returns

Lynn Parsons is considering investing in either of two outstanding bonds. The bonds both have $1,000 par values and 12% coupon interest rates and pay annual interest. Bond A has exactly 9 years to maturity, and bond B has 19

years to maturity.

a. Calculate the present value of bond A if the required rate of return is: (1) 9%, (2) 12%, and (3)

15%.

b. Calculate the present value of bond B if the required rate of return is: (1) 9%, (2) 12%, and (3) 15%.

c. From your findings in parts a and b, discuss the relationship between time to maturity and changing required returns.

d. If Lynn wanted to minimize interest rate risk, which bond should she purchase? Why?
