Derivative Instruments

From time to time, the Company enters into interest rate swap agreements with certain borrowers to assist them in mitigating their interest rate risk exposure associated with the loans they have with the Company. At the same time, the Company enters into identical interest rate swap agreements with another financial institution to mitigate the Company’s interest rate risk exposure associated with the swap agreements it enters into with its borrowers. The Company had swaps with matched terms with an aggregate notional amount of $57.7 million and a fair value of $3.3 million at June 30, 2018 compared with and aggregate notional amount of $58.6 million and a fair value of $1.1 million at December 31, 2017. The fair value of these agreements are determined through a third party valuation model used by the Company's counterparty bank, which uses observable market data such as cash LIBOR rates, prices of Eurodollar future contracts and market swap rates. The fair values of these swaps are recorded as components of other assets and other liabilities in the Company’s condensed consolidated balance sheet. Changes in the fair value of these swaps, which occur due to changes in interest rates, are recorded in the Company’s income statement as a component of noninterest income. Since the terms of the swap agreements between the Company and its borrowers have been matched with the terms of swap agreements with another financial institution, the adjustments for the change in their fair value offset each other in non-interest income.

Although changes in the fair value of swap agreements between the Company and borrowers and the Company and other financial institutions offset each other, changes in the credit risk of these counterparties may result in a difference in the fair value of these swap agreements. Offsetting swap agreements the Company has with other financial institutions are collateralized with cash, and swap agreements with borrowers are secured by the collateral arrangements for the underlying loans these borrowers have with the Company. During the six months ended June 30, 2018 and December 31, 2017, there were no losses recorded on swap agreements, attributable to the change in credit risk associated with a counterparty. All interest rate swap agreements entered into by the Company as of June 30, 2018 and December 31, 2017 are not designated as hedging instruments.
