Use the following information for Questions 14 : Consider a bond with the following features and a hypothetical settlement date of 17 October 2022. 1. Calculate the current full price of the bond (PV0). 2. Assume a 10 bp change in annual yield to maturity to approximate the bond's modified duration. The formula is (2Y2eldPV6)PVPV+. 3. Assume a 10 bp change in annual yield to maturity to approximate the bond's convexity. The formula is (ried2rv6)PV+PV42rV2, 4. What is the approximate percentage price change if the bond's yield to maturity decreases by 50 basis points? Use the formula that relies on modified duration and convexity. Round your answer to three decimal places and express your answer in percentage terms (e.g., 3.500\% not 0.035 )
