At December 31, 2021 and 2020, deposits exceeding the FDIC's Standard Maximum Deposit Insurance Amount of $250,000 were $7.6 billion and $6.4 billion, respectively. The Corporation experienced increases from December 31, 2020 in demand and savings accounts of $883.0 million and $673.1 million, respectively. A portion of the increase is due to PPP loans that have remained on deposit, in addition to consumer Economic Impact Payments from the IRS that have also remained on deposit. Offsetting these increases were decreases in certificates of deposit and brokered deposits of $142.2 million and $42.9 million, respectively, from December 31, 2020. The low interest rate environment has resulted in customers migrating funds from maturing time deposit products into non-maturity products due to similar rates offered for both products.

At December 31, 2021, the contractual maturities of time deposits are summarized as follows:
