Village Bank has $240 million worth of assets with a duration of 12 years and liabilities worth $216 million with a duration of five years. In the interest of hedging interest rate risk, Village Bank is contemplating a macrohedge with interest rate T-bond futures contracts now selling for 104-22 (31nds). The T-bond underlying the futures contract has a duration of seven years. If the spot and futures interest rates move together, how many futures contracts must Village Bank sell to fully hedge the balance sheet? (Negative amount should be indicated by a minus sign. Do not round intermediate calculations. Round your answer to the nearest whole number.)
