Suppose you purchased, a 27-year, 6.39 percent coupon (annual payments) bond at par. You hold it for 4 years and sell it so that you can take a vacation to Virgin Islands. At the time you sell the bond, 23-year bonds with similar characteristics (e.g., default risk) sell at yields of 7.25 percent. Calculate bond's realized yield. Round the answers to two decimal places in percentage form.
