During 2022, Trustmark reclassified a total of $766.0 million of securities available for sale to securities held to maturity. On the date of these transfers, the net unrealized holding loss on the available for sale securities totaled approximately $91.9 million ($68.9 million, net of tax).

The securities were transferred at fair value, which became the cost basis for the securities held to maturity. The net unrealized holding loss will be amortized over the remaining life of the securities as a yield adjustment in a manner consistent with the amortization or accretion of the original purchase premium or discount on the associated security. There were no gains or losses recognized as a result of these transfers. At December 31, 2023, the net unamortized, unrealized loss on transferred securities included in accumulated other comprehensive income (loss) in the accompanying balance sheet totaled $57.6 million compared to approximately $69.2 million at December 31, 2022.

ACL on Securities

Securities Available for Sale

Quarterly, Trustmark evaluates if any security has a fair value less than its amortized cost. Once these securities are identified, in order to determine whether a decline in fair value resulted from a credit loss or other factors, Trustmark performs further analysis. If Trustmark determines that a credit loss exists, the credit portion of the allowance is measured using a DCF analysis using the effective interest rate as of the security’s purchase date. The amount of credit loss Trustmark records will be limited to the amount by which the amortized

cost exceeds the fair value. The DCF analysis utilizes contractual maturities, as well as third-party credit ratings and cumulative default rates published annually by Moody’s.

At both December 31, 2023 and 2022, the results of the loss analysis performed did not identify any securities that warranted DCF analysis and no credit loss was recognized on any of the securities available for sale.

Accrued interest receivable is excluded from the estimate of credit losses for securities available for sale. At December 31, 2023 and 2022, accrued interest receivable totaled $3.7 million and $4.0 million, respectively, for securities available for sale and was reported in other assets on the accompanying consolidated balance sheet.

Securities Held to Maturity

At December 31, 2023 and 2022, the potential credit loss exposure for Trustmark’s securities held to maturity was $340 thousand and $4.5 million, respectively, and consisted of municipal securities. After applying appropriate probability of default and loss given default assumptions, the total amount of current expected credit losses was deemed immaterial. Therefore, no reserve was recorded at December 31, 2023 and 2022.

Accrued interest receivable is excluded from the estimate of credit losses for securities held to maturity. At December 31, 2023 and 2022, accrued interest receivable totaled $2.6 million and $2.7 million for securities held to maturity and was reported in other assets on the accompanying consolidated balance sheet.

At both December 31, 2023 and 2022, Trustmark had no securities held to maturity that were past due 30 days or more as to principal or interest payments. Trustmark had no securities held to maturity classified as nonaccrual at December 31, 2023 and 2022.

Trustmark monitors the credit quality of securities held to maturity on a monthly basis through credit ratings. The following table presents the amortized cost of Trustmark’s securities held to maturity by credit rating, as determined by Moody’s, at December 31, 2023 and 2022 ($ in thousands):

The unrealized losses shown above are due to increases in market rates over the yields available at the time of purchase of the underlying securities and not credit quality. Trustmark does not intend to sell these securities and it is more likely than not that Trustmark will not be required to sell the investments before recovery of their amortized cost bases, which may be at maturity.

Securities Gains and Losses

Realized gains and losses are determined using the specific identification method and are included in noninterest income as securities gains (losses), net. For the years ended December 31, 2023, 2022 and 2021, gross realized gains or losses as a result of calls and dispositions of securities, as well as any associated proceeds, were as follows ($ in thousands):

Securities Pledged

Securities with a carrying value of $2.321 billion and $2.693 billion at December 31, 2023 and 2022, respectively, were pledged to collateralize public deposits and securities sold under repurchase agreements and for other purposes as permitted by law. At both December 31, 2023 and 2022, none of these securities were pledged under the Federal Reserve Discount Window program to provide additional contingency funding capacity.

Contractual Maturities

The amortized cost and estimated fair value of securities available for sale and held to maturity at December 31, 2023, by contractual maturity, are shown below ($ in thousands). Expected maturities may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.
