 CASH AND DUE FROM DEPOSITORY INSTITUTIONS
Included in “Cash and due from depository institutions” are required federal reserves of $3.6 million for December 31, 2018 and $5.2 million for December 31, 2017, respectively, for facilitating the implementation of monetary policy by the Federal Reserve System. The required reserves are computed by applying prescribed ratios to the classes of average deposit balances. These are held in the form of vault cash and a depository amount held with the Federal Reserve Bank.
