On April 4, 2013, Trustmark entered into a forward interest rate swap contract on junior subordinated debentures with a total notional amount of $60.0 million. The interest rate swap contract was designated as a derivative instrument in a cash flow hedge under FASB ASC Topic 815 with the objective of protecting the quarterly interest payments on Trustmark’s $60.0 million of junior subordinated debentures issued to Trustmark Preferred Capital Trust I throughout the five-year period beginning December 31, 2014 and ending December 31, 2019 from the risk of variability of those payments resulting from changes in the three-month LIBOR interest rate. Under the swap, which became effective on December 31, 2014, Trustmark will pay a fixed interest rate of 1.66% and receive a variable interest rate based on three-month LIBOR on a total notional amount of $60.0 million, with quarterly net settlements.

No ineffectiveness related to the interest rate swap designated as a cash flow hedge was recognized in the consolidated statements of income for the years ended December 31, 2018, 2017 and 2016. The accumulated net after-tax gain related to the effective cash flow hedge included in accumulated other comprehensive loss totaled $469 thousand at December 31, 2018 compared to a net after-tax gain of $278 thousand at December 31, 2017. Amounts reported in accumulated other comprehensive loss related to this derivative are reclassified to other interest expense as interest payments are made on Trustmark’s variable rate junior subordinated debentures. During the next twelve months, Trustmark estimates that $625 thousand will be reclassified as a decrease to other interest expense.

Trustmark utilizes a portfolio of exchange-traded derivative instruments, such as Treasury note futures contracts and option contracts, to achieve a fair value return that economically hedges changes in the fair value of the MSR attributable to interest rates. These transactions are considered freestanding derivatives that do not otherwise qualify for hedge accounting. The total notional amount of these derivative instruments was $318.0 million at December 31, 2018 compared to $349.0 million at December 31, 2017. Changes in the fair value of these exchange-traded derivative instruments are recorded as noninterest income in mortgage banking, net and are offset by changes in the fair value of the MSR. The impact of this strategy resulted in a net positive ineffectiveness of $2.4 million for the year ended December 31, 2018, compared to a net positive ineffectiveness of $254 thousand for the year ended December 31, 2017 and a net negative ineffectiveness of $2.9 million for the year ended December 31, 2016.

As part of Trustmark’s risk management strategy in the mortgage banking area, derivative instruments such as forward sales contracts are utilized. Trustmark’s obligations under forward sales contracts consist of commitments to deliver mortgage loans, originated and/or purchased, in the secondary market at a future date. Changes in the fair value of these derivative instruments are recorded as noninterest income in mortgage banking, net and are offset by changes in the fair value of LHFS. Trustmark’s off-balance sheet obligations under these derivative instruments totaled $132.0 million at December 31, 2018, with a negative valuation adjustment of $1.8 million, compared to $182.1 million at December 31, 2017, with a negative valuation adjustment of $237 thousand.

Trustmark also utilizes derivative instruments such as interest rate lock commitments in its mortgage banking area. Interest rate lock commitments are residential mortgage loan commitments with customers, which guarantee a specified interest rate for a specified time period. Changes in the fair value of these derivative instruments are recorded as noninterest income in mortgage banking, net and are offset by the changes in the fair value of forward sales contracts. Trustmark’s off-balance sheet obligations under these derivative instruments totaled $71.2 million at December 31, 2018, with a positive valuation adjustment of $1.2 million, compared to $83.0 million at December 31, 2017, with a positive valuation adjustment of $900 thousand.

Trustmark offers certain derivatives products directly to qualified commercial lending clients seeking to manage their interest rate risk. Trustmark economically hedges interest rate swap transactions executed with commercial lending clients by entering into offsetting interest rate swap transactions with institutional derivatives market participants. Derivatives transactions executed as part of this program are not designated as qualifying hedging relationships and are, therefore, carried at fair value with the change in fair value recorded as noninterest income in bank card and other fees. Because these derivatives have mirror-image contractual terms, in addition to collateral provisions which mitigate the impact of non-performance risk, the changes in fair value are expected to substantially offset. As of December 31, 2018, Trustmark had interest rate swaps with an aggregate notional amount of $475.8 million related to this program, compared to $351.9 million as of December 31, 2017.

Trustmark has agreements with its financial institution counterparties that contain provisions where if Trustmark defaults on any of its indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender, then Trustmark could also be declared in default on its derivatives obligations.

As of December 31, 2018 and 2017, the termination value of interest rate swaps in a liability position, which includes accrued interest but excludes any adjustment for nonperformance risk, related to these agreements was $75 thousand and $80 thousand, respectively. As of December 31, 2018, Trustmark had no posted collateral against its obligations because of negotiated thresholds and minimum transfer amounts under these agreements. If Trustmark had breached any of these triggering provisions at December 31, 2018, it could have been required to settle its obligations under the agreements at the termination value.

Credit risk participation agreements arise when Trustmark contracts with other financial institutions, as a guarantor or beneficiary, to share credit risk associated with certain interest rate swaps. These agreements provide for reimbursement of losses resulting from a third party default on the underlying swap. At December 31, 2018, Trustmark had entered into three risk participation agreements as a beneficiary with an aggregate notional amount of $23.1 million compared to two risk participation agreements as a beneficiary with an aggregate notional amount $13.7 million at December 31, 2017. At December 31, 2018, Trustmark had entered into seven risk participation agreements as a guarantor with an aggregate notional amount of $39.0 million compared to six risk participation agreements as a guarantor with an aggregate notional amount of $37.1 million at December 31, 2017. The aggregate fair values of these risk participation agreements were immaterial at December 31, 2018 and 2017.
