In August 2017, the FASB issued ASU No. 2017-12, “Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities" and subsequent related updates. The Corporation adopted this guidance effective January 1, 2019, on a modified retrospective basis through a cumulative-effect adjustment to retained earnings at January 1, 2019. See Note 1, "Summary of Significant Accounting Policies - Accounting Pronouncements Adopted in 2019" for additional information.

The Corporation may use interest rate swap agreements to modify interest rate characteristics from variable to fixed or fixed to variable in order to reduce the impact of interest rate changes on future net interest income. Recorded amounts related to interest rate swaps are included in other assets or liabilities. The Corporation’s credit exposure on interest rate swaps includes fair value and any collateral that is held by a third party. Changes in the fair value of derivative instruments designated as hedges of future cash flows are recognized in accumulated other comprehensive income until the underlying transactions occur, at which time the deferred gains and losses are recognized in earnings. For a qualifying fair value hedge, the gain or loss on the hedging instrument is recognized in earnings, and the change in fair value of the hedge item, to the extent attributable to the hedged risk, adjusts the carrying amount of the hedge item and is recognized in earnings.

In 2014, the Corporation entered into an amortizing interest rate swap classified as a cash flow hedge with a notional amount of $20.0 million to hedge a portion of the debt financing of a pool of 10-year fixed rate loans with balances totaling $29.1 million, at time of the hedge, that were originated in 2013. A brokered money market demand account with a balance

exceeding the amortizing interest rate swap balance is being used for the cash flow hedge. Under the terms of the swap agreement, the Corporation pays a fixed rate of 2.10% and receives a floating rate of one-month LIBOR. The swap matures in November 2022. The Corporation performed an assessment of the hedge for effectiveness at the inception of the hedge and on a recurring basis to determine that the derivative has been and is expected to continue to be highly effective in offsetting changes in cash flows of the hedged item. At September 30, 2019, approximately $49 thousand in net deferred losses, net of tax, recorded in accumulated other comprehensive loss are expected to be reclassified into earnings during the next twelve months. This amount could differ from amounts actually recognized due to changes in interest rates, hedge de-designations, and the addition of other hedges subsequent to September 30, 2019. At September 30, 2019, the notional amount of the interest rate swap was $16.5 million, with a negative fair value of $326 thousand.

The Corporation had an interest rate swap classified as a fair value hedge for a 10-year fixed rate loan that was earning interest at 5.83%. The interest rate swap was terminated due to early payoff of the loan during the third quarter of 2019. The Corporation paid a fixed rate of 5.83% and received a floating rate based on the one-month LIBOR plus 350 basis points. The swap was due to mature in October 2021. Effective January 1, 2019, the entire change in the fair values of the interest rate swap and the hedged loan included in the assessment of hedge effectiveness was recorded in interest income in the consolidated statements of income. Prior to January 1, 2019, the difference between changes in the fair values of the interest rate swap agreement and the hedged loan represented hedge ineffectiveness and was recorded in other noninterest income in the consolidated statements of income.

The Corporation has an interest rate swap with a current notional amount of $332 thousand, for a 15-year fixed rate loan that is earning interest at 7.43%. The Corporation pays a fixed rate of 7.43% and receives a floating rate based on the one-month LIBOR plus 224 basis points. The swap matures in April 2022. The interest rate swap is carried at fair value in accordance with FASB ASC 815 "Derivatives and Hedging." The loan is carried at fair value under the fair value option as permitted by FASB ASC 825 "Financial Instruments."

The Corporation has agreements with third-party financial institutions whereby the third-party financial institution enters into interest rate derivative contracts with loan customers referred to them by the Corporation. By the terms of the agreements, the third-party financial institution has recourse to the Corporation for any exposure created under each swap contract in the event the customer defaults on the swap agreement and the agreement is in a paying position to the third-party financial institution. These transactions represent credit derivatives and are a customary arrangement that allows the Corporation to provide access to interest rate transactions for customers without creating the swap. The Corporation records the fair value of credit derivatives in other liabilities on the consolidated balance sheets. The Corporation recognizes changes in the fair value of credit derivatives, net of any fees received, in other noninterest income in the consolidated statements of income.

At September 30, 2019, the Corporation has thirty-three variable-rate to fixed-rate interest rate swap transactions between the third-party financial institution and customers with a current notional amount of $221.4 million and remaining maturities ranging from less than one year to 10 years. At September 30, 2019, the fair value of the swaps to the customers was a net liability of $11.9 million and $187.2 million of notional amount of the swaps were in paying positions while $34.2 million were in receiving positions to the third-party financial institution. At September 30, 2019, the fair value of the Corporation's interest rate swap credit derivatives was a liability of $263 thousand.

The maximum potential payments by the Corporation to the third-party financial institution under these credit derivatives are not estimable as they are contingent on future interest rates and the agreement does not provide for a limitation of the maximum potential payment amount.

Derivative loan commitments represent agreements for delayed delivery of financial instruments in which the buyer agrees to purchase and the seller agrees to deliver, at a specified future date, a specified instrument at a specified price or yield. The Corporation’s derivative loan commitments are commitments to sell loans secured by 1-to 4-family residential properties whose predominant risk characteristic is interest rate risk. The fair values of these derivative loan commitments are based upon the estimated amount the Corporation would receive or pay to terminate the contracts or agreements, taking into account current interest rates and, when appropriate, the current creditworthiness of the counterparties.

The following table presents the notional amounts and fair values of derivatives designated as hedging instruments recorded on the consolidated balance sheets at September 30, 2019 and December 31, 2018. The Corporation pledges cash or securities to cover the negative fair value of derivative instruments. Cash collateral associated with derivative instruments are not added to or netted against the fair value amounts.
