The Company enters into derivative financial instruments to manage risks related to differences in the amount, timing, and duration of the Company’s known or expected cash receipts and its known or expected cash payments. The Bank also entered into interest rate derivative agreements as a service to certain qualifying customers. The Bank manages a matched book with respect to these customer derivatives in order to minimize its net interest rate risk exposure resulting from such agreements. In addition, the Bank also enters into risk participation agreements under which it may either sell or buy credit risk associated with a customer’s performance under certain interest rate derivative contracts related to loans in which participation interests have been sold to or purchased from other banks.

The table below presents the notional or contractual amounts and fair values of the Company’s derivative financial instruments as well as their classification on the consolidated balance sheets at March 31, 2021 and December 31, 2020.

The Company is party to various interest rate swap agreements designated and qualifying as cash flow hedges of the Company’s forecasted variable cash flows for pools of variable rate loans. For each agreement, the Company receives interest at a fixed rate and pays at a variable rate. The notional amounts of the swap agreements in place at March 31, 2021 expire as follows: $50 million in 2021; $475 million in 2022; $550 million in 2023; $100 million in 2024; $250 million thereafter.

The Company is party to forward-starting fixed payer swaps that convert the latter portion of the term of certain available for sale securities to a floating rate. These derivative instruments are designated as fair value hedges of interest rate risk. This strategy provides the Company with a fixed rate coupon during the front-end unhedged tenor of the bonds and results in a floating rate security during the back-end hedged tenor with hedged start dates between August 2023 through September 2025, and maturity dates from December 2027 through March 2031. The fair value of the hedged item attributable to interest rate risk will be presented in interest income along with the change in the fair value of the hedging instrument.

The majority of the hedged available for sale securities is a closed portfolio of pre-payable commercial mortgage backed securities. In accordance with ASC 815, prepayment risk may be excluded when measuring the change in fair value of such hedged items attributable to interest rate risk under the last-of-layer approach. At March 31, 2021, the amortized cost basis of the closed portfolio of pre-payable commercial mortgage backed securities totaled $1.7 billion. The amount that represents the hedged items was $1.4 billion and the basis adjustment associated with the hedged items totaled $55.5 million.

The Bank enters into interest rate derivative agreements, primarily rate swaps, with commercial banking customers to facilitate their risk management strategies. The Bank enters into offsetting agreements with unrelated financial institutions, thereby mitigating its net risk exposure resulting from such transactions. Because the interest rate derivatives associated with this program do not meet hedge accounting requirements, changes in the fair value of both the customer derivatives and the offsetting derivatives are recognized directly in earnings.

The Bank also enters into risk participation agreements under which it may either assume or sell credit risk associated with a borrower’s performance under certain interest rate derivative contracts. In those instances where the Bank has assumed credit risk, it is not a direct counterparty to the derivative contract with the borrower and has entered into the risk participation agreement because it is a party to the related loan agreement with the borrower. In those instances in which the Bank has sold credit risk, it is the sole counterparty to the derivative contract with the borrower and has entered into the risk participation agreement because other banks participate in the related loan agreement. The Bank manages its credit risk under risk participation agreements by monitoring the creditworthiness of the borrower, based on the Bank’s normal credit review process.

The Bank also enters into certain derivative agreements as part of its mortgage banking activities. These agreements include interest rate lock commitments on prospective residential mortgage loans and forward commitments to sell these loans to investors on a best efforts delivery basis.

The Company enters into foreign exchange forward derivative agreements, primarily forward foreign currency contracts, with commercial banking customers to facilitate their risk management strategies. The Bank manages its risk exposure from such transactions by entering into offsetting agreements with unrelated financial institutions. The Bank has not elected to designate these foreign exchange forward contract derivatives as hedge; as such changes in the fair value of both the customer derivatives and the offsetting derivatives are recognized directly in earnings.

The Company is a member of Visa USA. During the fourth quarter of 2018, the Company sold the majority of its Visa Class B holdings, at which time it entered into a derivative agreement with the purchaser whereby the Company will make or receive cash payments whenever the conversion ratio of the Visa Class B shares into Visa Class A shares is adjusted. The conversion ratio changes when Visa deposits funds to a litigation escrow account established by Visa to pay settlements for certain litigation, for which Visa is

indemnified by Visa USA members. The Company is also required to make periodic financing payments to the purchaser until all of Visa’s covered litigation matters are resolved. Thus, the derivative contract extends until the end of Visa’s covered litigation matters, the timing of which is uncertain.

The contract includes a contingent accelerated termination clause based on the credit ratings of the Company. At March 31, 2021 and December 31, 2020, the fair value of the liability associated with this contract was $5.3 million and $5.6 million, respectively. Refer to Note 13 – Fair Value of Financial Instruments for discussion of the valuation inputs and process for this derivative liability.

The effects of derivative instruments on the consolidated statements of income for the three months ended March 31, 2021 and 2020 are presented in the table below. Interest income or the reduction of interest income attributable to cash flow hedges includes amortization of accumulated other comprehensive loss that resulted from termination of certain interest rate swap contracts.

Certain of the Bank’s derivative instruments contain provisions allowing the financial institution counterparty to terminate the contracts in certain circumstances, such as a downgrade of the Bank’s credit ratings below specified levels, a default by the Bank on its indebtedness, or the failure of the Bank to maintain specified minimum regulatory capital ratios or its regulatory status as a well-capitalized institution. These derivative agreements also contain provisions regarding the posting of collateral by each party. At March 31, 2021, the Company was not in violation of any such provisions. The aggregate fair value of derivative instruments with credit risk-related contingent features that were in a net liability position at March 31, 2021 and December 31, 2020 was $16.0 million and $109.7 million, respectively, for which the Company had posted collateral of $18.4 million and $44.7 million, respectively.

The Bank’s derivative instruments with certain counterparties contain legally enforceable netting provisions that allow for net settlement of multiple transactions to a single amount, which may be positive, negative, or zero. Agreements with certain bilateral counterparties require both parties to maintain collateral in the event that the fair values of derivative instruments exceed established exposure thresholds. For centrally cleared derivatives, the Company is subject to initial margin posting and daily variation margin exchange with the central clearinghouses. Offsetting information in regards to all derivative assets and liabilities, including accrued interest, subject to these master netting agreements at March 31, 2021 and December 31, 2020 is presented in the following tables.

The Company has excess collateral compared to total exposure due to initial margin requirements for day-to-day rate volatility.
