Using the prices and cash flows of Treasury coupon bonds shown below, determine the par bond yield for each of the Treasury securities.

Bond	Price	Year 1	Year 2	Year 3
1	99.50	105
2	101.25	6	106
3	100.25	7	7	107

Using Excel, solve the above problem and graph the resulting Treasury par bond yield curve (show formula). Suppose that the 6-month, 12-month, 18-month, and 24-month zero rates are 5%, 6%, 6.5%, and 7% respectively. What is the two-year par yield?
