Investment securities have been classified in the consolidated balance sheets according to management’s intent. Available-for-sale securities consist of debt securities not classified as trading or held to maturity. Available-for-sale securities are stated at fair value, and unrealized holding gains and losses, net of the related deferred tax effect, are reported as a separate component of stockholders' equity. As of June 30, 2026 and December 31, 2025, all securities held were rated investment grade based upon external ratings where available and, where not available, based upon management knowledge of the local issuers and their financial situations. The Company has no securities designated as trading or held to maturity in its portfolio as of June 30, 2026 or December 31, 2025.

The Company considered the following information in reaching the conclusion that the unrealized losses disclosed in the table above are not attributable to credit losses. None of the unrealized losses in the above table were due to the deterioration in the credit quality of any of the issues that might result in the non-collection of contractual principal and interest. The unrealized losses are due to changes in interest rates. The Company completed several balance sheet repositioning transactions related to its investment securities portfolio throughout the last four months of 2025. This consisted of the sale of lower-yielding AFS debt securities resulting in a pre-tax realized loss on the sales of $9.63 million in total for 2025. All of the proceeds from the sale of these securities were used to purchase AFS debt securities at higher yields to improve income going forward, while maintaining the liquidity provided by the investment portfolio. Management has concluded that it is more likely than not that the Company will not be required to sell these securities prior to recovery of the amortized cost basis. The securities are of high credit quality (investment grade credit ratings) and principal and interest payments are made timely with no payments past due as of June 30, 2026. The fair value is expected to recover as the securities approach maturity. The Company evaluates whether a credit loss exists by monitoring to ensure it has adequate credit support considering the nature of the investment, number and significance of investments in an unrealized loss position, collectability or delinquency issues, the underlying financial statements of the issuers, credit ratings and subsequent changes thereto, and other available relevant information. Considering the above factors, management has determined that no allowance for credit losses is necessary for the securities portfolio as of June 30, 2026.

The Company held Visa Class B common stock received in connection with Visa's restructuring. During April 2026, the Company sold its Visa Class B shares and recognized a gain of approximately $1.69 million in gain on sale of investment securities. At June 30, 2026, no Visa Class B shares remained outstanding.
