A 6% cоupоn bоnd mаkes semi-аnnuаl coupon payments and has two years until maturity and a yield to maturity of 6%. The bond has a par value of $1,000. What is the modified duration of this bond? Round your answer to two decimal places. (Hint: Make sure to account for the semi-annual periodicity in your calculation here – i.e., you should use YTM / 2 in the formula for modified duration)
