Currently, the term structure is as follows: One-year bonds yield 10.50%, two-year zero-coupon bonds yield 11.50%, three-year and onger maturity zero-coupon bonds all yield 12.50%. You are choosing between one, two, and three-year maturity bonds all paying innual coupons of 11.50%. You strongly believe that at year-end the yield curve will be flat at 12.50%. ?equired: 1.
