Suppose that the current 1-year rate (1-year spot rate) and expected 1-year T-bill rates over the following three years (.e., years 2, 3, and 4, respectively) are as follows: 1R1 = 4%, E(211) = 5%, E311) = 5.50%, E(411) = 5.85% Using the unbiased expectations theory, calculate the current (long-term) rates for 1-, 2-, 3-, and 4-year- maturity Treasury securities (Round your answers to 2 decimal places.)
