The Bank occasionally uses derivative financial instruments, such as interest rate swaps and interest rate floors and caps, as part of its interest rate risk management. Interest rate caps and floors are agreements whereby one party agrees to pay or receive a floating rate of interest on a notional principal amount for a predetermined period of time if certain market interest rate thresholds are met. The Bank considers the credit risk inherent in these contracts to be negligible.

The Bank is a party to interest rate derivatives that are not designated as hedging instruments. Under a program, the Bank executes interest rate swaps with commercial lending customers to facilitate their respective risk management strategies. These interest rate swaps with customers are simultaneously offset by interest rate swaps that the Bank executes with a third-party financial institution, such that the Bank minimizes its net risk exposure resulting from such transactions. Because the interest rate swaps associated with this program do not meet the strict hedge accounting requirements, changes in the fair value of both the customer swaps and the offsetting swaps are recognized directly in earnings. The changes in the fair value of the swaps offset each other, except for the credit risk of the counterparties, which is determined by taking into consideration the risk rating, probability of default and loss given default for all counterparties. The Bank had $200,000 in cash pledged for collateral on its interest rate swaps with financial institutions at June 30, 2021 and none in cash pledged for collateral on its interest rate swaps with financial institutions at September 30, 2020.

As of June 30, 2021 and September 30, 2020, the Company did not hold any interest rate floors or collars.
