B. Estimate term structure of discount factors, spot rates and forward rates by using data on five semi-annual coupon paying bonds with $100 face value each: The bonds, respectively, have 1.25, 5.35, 10.4, 15.15 and 20.2 years to maturity; pay coupon at annual rates of B1, B2, B3, B4, and B5 percent of face value; and are trading at quoted spot market prices in dollars of B6, B7, B8, B9 and B10. Specify the discount factor function d(t) by a third degree polynomial with unknown parameters a, b, and c, as done in class. Using estimated d(t) function, determine spot rate and forward rate functions by assuming half-year compounding. Then write the values of the following based on your estimation.

9. Coefficient of parameter c in third bond price equation.

10. Coefficient of parameter a in fourth bond price equation.

11. Coefficient of parameter b in fourth bond price equation.

12. Coefficient of parameter c in fourth bond price equation.

13. Coefficient of parameter a in fifth bond price equation.

14. Coefficient of parameter b in fifth bond price equation.

15. Coefficient of parameter c in fifth bond price equation.
