A 4% coupon bond has a par value of $1,000 and a yield-to-maturity of 8.1%. You purchase the bond when it has exactly 15 years remaining until maturity. You hold the bond for 6 months, collect the coupon payment, and then sell the bond immediately. If the bond's yield-to-maturity doesn't change between the time you buy and sell the bond, what is your percentage return over this 6-month holding period? Enter your answer as a decimal and show 4 decimal places. For example, if your answer is 6.25%, enter .0625
