Derivatives and hedging activities |
Derivatives and hedging activities | 15. Derivatives and hedging activities: Risk Management Objective of Using Derivatives The Company is exposed to certain risk arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity, and credit risk primarily by managing the amount, sources, and duration of its assets and liabilities and the use of derivative financial instruments. Specifically, the Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. The Company’s derivative financial instruments are used to manage differences in the amount, timing, and duration of the Company’s known or expected cash receipts principally related to the Company’s assets and borrowings. ​ Cash Flow Hedges of Interest Rate Risk ​ The Company’s objectives in using interest rate derivatives are to add stability to interest income/expense and to manage its exposure to interest rate movements. To accomplish this objective, the Company primarily uses interest rate swaps and floors as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. Interest rate floors designated as cash flow hedges involve the receipt of variable-rate amounts from a counterparty if interest rates fall below the strike rate on the contract in exchange for an up-front premium. During 2020, such derivatives were used to hedge the variable cash flows associated with existing variable-rate assets and issuances of debt. ​ The Company executed an interest rate swap to reduce its exposure to variability in the interest rate associated with floating-rate borrowings. For derivatives designated and that qualify as cash flow hedges of interest rate risk, the gain or loss on the derivative is recorded in Accumulated Other Comprehensive Income and subsequently reclassified into interest expense/income in the same period(s) during which the hedged transaction affects earnings. Amounts reported in accumulated other comprehensive income related to derivatives will be reclassified to interest expense/income as interest payments are made/received on the Company’s variable-rate debt/assets. During 2021 the Company estimates that an additional $50 will be reclassified as a decrease to interest income. Non-designated Hedges Derivatives not designated as hedges are not speculative and result from a service the Company provides to certain customers. The Company executes interest rate swaps with commercial banking customers to facilitate their respective risk management strategies. Those interest rate swaps are simultaneously hedged by offsetting interest rate swaps that the Company executes with a third party, such that the Company minimizes its net risk exposure resulting from such transactions. As 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. As of December 31, 2020, the Company had 73 interest rate swaps with an aggregate notional amount of $375,341 related to this program. ​ Fair Values of Derivative Instruments on the Balance Sheet The table below presents the fair value of the Company’s derivative financial instruments as well as their classification on the Consolidated Balance Sheets as of December 31, 2020 and December 31, 2019. ​

​ Credit-risk-related Contingent Features ​ The Company has agreements with certain of its derivative counterparties that contain a provision where if the Company defaults on any of its indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender, then the Company could also be declared in default on its derivative obligations. The Company also has agreements with certain of its derivative counterparties that contain a provision where if the Company fails to maintain its status as a well capitalized institution, then the counterparty could terminate the derivative positions and the Company would be required to settle its obligations under the agreements. As of December 31, 2020, the termination value of derivatives in a net asset position, which includes accrued interest but excludes any adjustment for nonperformance risk, related to these agreements was $79. As of December 31, 2019, the termination value of derivatives in a net asset position, which includes accrued interest but excludes any adjustment for nonperformance risk, related to these agreements was $48. The Company has minimum collateral posting thresholds with certain of its derivative counterparties, and has posted collateral of $15,360 against its obligations under these agreements as of December 30, 2020, compared to having posted collateral of $4,140 with counterparties at December 31, 2019. If the Company had breached any of these provisions it could have been required to settle its obligations under the agreements at the termination value.
