The Company has 27 debt securities in the less than twelve month category and 188 debt securities in the twelve months or more category as of December 31, 2024. In management’s opinion, the unrealized losses on securities reflect changes in interest rates subsequent to the acquisition of specific securities. The Company does not intend to sell the securities in an unrealized loss position and is unlikely to be required to sell these securities before a recovery of fair value, which may be maturity. The Company concluded that the decline in fair value of these securities was not indicative of a credit loss. No securities in the portfolio required an allowance for credit losses to be recorded during the years ended December 31, 2024 and 2023. In December 2024, the Company did decide to sell a portion of the securities portfolio in order to take advantage of higher yields that could be attained on reinvesting those bonds. The goal was to increase the overall portfolio yield and thus increase net income for the Company.

The amortized cost and fair value of debt securities as of December 31, 2024 by contractual maturity, are shown below. Expected maturities may differ from contractual maturities because borrowers may have the right to prepay obligations with or without call or prepayment penalties.
