DERIVATIVE FINANCIAL INSTRUMENTS AND HEDGING ACTIVITIES |
DERIVATIVE FINANCIAL INSTRUMENTS AND HEDGING ACTIVITIES | ​ ​ NOTE 8. DERIVATIVE FINANCIAL INSTRUMENTS AND HEDGING ACTIVITIES ​ We use derivative instruments to minimize fluctuations in earnings and cash flows caused by interest rate volatility. Our interest rate risk management strategy involves modifying the re-pricing characteristics of certain assets or liabilities so the changes in interest rates do not have a significant effect on net interest income. Thus, all of our derivative contracts are considered to be interest rate contracts. ​ We recognize our derivative instruments on the consolidated balance sheet at fair value. On the date the derivative instrument is entered into, we designate whether the derivative is part of a hedging relationship (i.e., cash flow or fair value hedge). We formally document relationships between hedging instruments and hedged items, as well as our risk management objective and strategy for undertaking hedge transactions. We also assesses, both at the hedge’s inception and on an ongoing basis, whether the derivatives used in hedging transactions are highly effective in offsetting the changes in cash flows or fair values of hedged items. Changes in fair value of derivative instruments that are highly effective and qualify as cash flow hedges are recorded in other comprehensive income or loss. ​ We offer derivative products in the form of interest rate swaps, to commercial loan customers to facilitate their risk management strategies. These instruments are executed through Master Netting Arrangements (MNA) with financial institution counterparties or Risk Participation Agreements (RPA) with commercial bank counterparties, for which we assumes a pro rata share of the credit exposure associated with a borrower's performance related to the derivative contract with the counterparty. ​ The following tables present information about derivative assets and liabilities at March 31, 2022 and December 31, 2021: ​

​ Cash flow hedges ​ Interest rate swaps on wholesale funding As of March 31, 2022 we have two interest rate swaps on wholesale borrowings (the "SWAPS") to limit our exposure to rising interest rates over a five year term on 3-month FHLB borrowings or brokered certificates, or a combination thereof at each maturity date. The first of the two agreements were entered in November 2019 with a $50.0 million notional amount and pays a fixed interest rate of 1.53%. A second agreement was entered on April 2020 with a $25.0 million notional amount and pays a fixed rate of 0.59%. The financial institution counterparty pays us interest on the three-month LIBOR rate. We designated the swaps as cash flow hedges. ​ Interest rate swap on variable rate loans We have an interest rate swap that effectively fixes our interest rate on $50 million of 1 month USD-LIBOR-BBA (or LIBOR less two days) based loan assets at 0.806% plus the credit spread on the loans that reprices on weighted average basis. The instrument is specifically designed to hedge the risk of changes in its cash flows from interest receipts attributable to changes in a contractually specified interest rate, on an amount of our variable rate loan assets equal to $50 million. We designated the swap as a cash flow hedge. ​ ​ ​ ​ Fair value hedges ​ Interest rate swap on securities For derivative instruments that are designated and qualify as a fair value hedge, the gain or loss on the derivative instrument as well as the offsetting loss or gain on the hedged asset or liability attributable to the hedged risk are recognized in current earnings. We utilize interest rate swaps designated as fair value hedges to mitigate the effect of changing interest rates on the fair values of fixed rate callable securities available-for-sale. The hedging strategy on securities converts the fixed interest rates to LIBOR-based variable interest rates. These derivatives are designated as partial term hedges of selected cash flows covering specified periods of time prior to the call dates of the hedged securities. During 2019, we entered into eight swap transactions with a notional amount of $37.2 million designated as fair value hedges. These derivatives are intended to protect against the effects of changing interest rates on the fair values of fixed rate securities. The fixed rates on the transactions have a weighted average of 1.696%. ​ Economic hedges ​ Forward sale commitments We utilize forward sale commitments on residential mortgage loans to hedge interest rate risk and the associated effects on the fair value of interest rate lock commitments and loans originated for sale. The forward sale commitments are accounted for as derivatives. We typically use a combination of best efforts and mandatory delivery contracts. The contracts are loan sale agreements where we commit to deliver a certain principal amount of mortgage loans to an investor at a specified price on or before a specified date. Generally, we enter into contracts just prior to the loan closing with a customer. ​ Customer loan derivatives We enter into customer loan derivatives to facilitate the risk management strategies for commercial banking customers. We mitigate this risk by entering into equal and offsetting loan swap agreements with highly rated third-party financial institutions. The loan swap agreements are free standing derivatives and are recorded at fair value in our consolidated balance sheet. We are party to master netting arrangements with our financial institutional counterparties; however, we do not offset assets and liabilities under these arrangements for financial statement presentation purposes. ​ The master netting arrangements provide for a single net settlement of all loan swap agreements, as well as collateral or cash funds, in the event of default on, or termination of, any one contract. Collateral is provided by cash or securities received or posted by the counterparty with net liability positions, respectively, in accordance with contract thresholds. ​

​ Non-hedging derivatives ​ Interest rate lock commitments We enter into interest rate lock commitments (IRLCs) for residential mortgage loans, which commit us to lend funds to a potential borrower at a specific interest rate and within a specified period of time. IRLCs relate to the origination of residential mortgage loans that are held for sale are considered derivative financial instruments under applicable accounting guidance. Outstanding IRLCs expose us to the risk that the price of the mortgage loans underlying the commitments may decline due to increases in mortgage interest rates from inception of the rate lock to the funding of the loan. The IRLCs are free standing derivatives which are carried at fair value with changes recorded in non-interest income in our Consolidated Statements of Income. Changes in the fair value of IRLCs subsequent to inception are based on; (i) changes in the fair value of the underlying loan resulting from the fulfillment of the commitment and (ii) changes in the probability when the loan will fund within the terms of the commitment, which is affected primarily by changes in interest rates and the passage of time.
