Three years ago, Jameson and Co. issued 20-year coupon bonds. The yield to maturity at the time of issuance was 5 percent and the bonds sold at par. The bonds are currently selling at 90 percent of par value. What is the current yield to maturity for these bonds? [Assume that the coupon is paid annually]. (Round your answer to 2 decimal places and record as a percent but without a percent sign. For example, record 18.3893 4.17 % as 18.39).
