Derivative Instruments and Hedging Activities Disclosure [Abstract]

The Company uses interest rate swaps to manage its interest rate risk and market risk in accommodating the needs of its customers. Interest rate swaps include both traditional interest rate swaps and interest rate swaps which can be canceled by the customer on specified dates at no cost, typically referred to as swaptions. The Company recognizes all derivatives on the consolidated balance sheet at fair value in either other assets or accrued expenses and other liabilities as appropriate.

The following table presents the notional amounts and gross fair values of all derivative assets and liabilities held by the Company as of September 30, 2020 and 2019.

Netting of Derivatives

The Company records the derivatives on a net basis when a right of offset exists, based on transactions with a single counterparty that are subject to a legally enforceable master netting agreement. When bilateral netting agreements or similar agreements exist between the Company and its counterparties that create a single legal claim or obligation to pay or receive the net amount in settlement of the individual derivative contracts, the Company reports derivative assets and liabilities on a net by derivative contract by counterparty basis.

The following tables provide information on the Company's netting adjustments as of September 30, 2020 and 2019.


	Gross Fair Value		Fair Value Offset Amount		Cash Collateral		Net Amount Presented on the Consolidated Balance Sheet

As with any financial instrument, derivative financial instruments have inherent risk including adverse changes in interest rates. The Company’s exposure to derivative credit risk is defined as the possibility of sustaining a loss due to the failure of the counterparty to perform in accordance with the terms of the contract. Credit risks associated with interest rate swaps are similar to those relating to traditional on-balance sheet financial instruments. The Company manages interest rate swap credit risk with the same standards and procedures applied to its commercial lending activities.

Credit-risk-related contingent features

The Company has agreements with its derivative counterparties that contain a provision where if the Company or the derivative counterparty fails to maintain its status as a well/adequately capitalized institution, then the counterparty has the right to terminate the derivative positions and the Company or the derivative counterparty would be required to settle its obligations under the agreements. The Company has minimum collateral pledging thresholds with its Swap Dealers and Futures Clearing Merchant.
