### Notes to Consolidated Financial Statements (cont.)

#### December 31, 2024
Investment in Marketable Securities

At acquisition, we designate a debt security as held-to-maturity, available-for-sale, or trading. As of December 31, 2024, we did not have any debt securities designated as trading. We account for our available-for-sale securities at fair value pursuant to ASC 820-10, with the net unrealized gains or losses reported as a component of accumulated other comprehensive income or loss. The cost of marketable securities sold and the amount reclassified out of accumulated other comprehensive income into earnings is determined using the specific identification method. We account for our held-to-maturity securities at amortized cost basis. Credit losses for our debt securities are recognized in accordance with ASC 326. Noallowance for loan losses were recognized
