As of March 31, 2024, the Company’s security portfolio consisted of 947 securities, 767 of which were in an unrealized loss position. The treasury, agency, mortgage-backed securities, collateralized mortgage obligations and small business administration securities that the Company owns are all issued by government sponsored entities and therefore contain no potential for credit loss. The Company does not consider any of its available-for-sale securities with unrealized losses to be attributable to credit-related factors, as the unrealized losses have occurred as a result of changes in noncredit related factors such as changes in interest rates, market spreads and market conditions subsequent to purchase, not credit deterioration. The vast majority of the Company's state and political subdivisions holdings are of high credit quality, and are rated AA or higher. In addition, management has both the ability and intent to hold the securities for a period of time sufficient to allow for the recovery in fair value. As of March 31, 2024, the Company has not recorded an allowance for credit losses on available for sale ("AFS") securities.

Equity Securities

The Company also holds equity securities which include $15.3 million in Small Business Investment Company (“SBIC”) partnership investments as well as $238 thousand in local and regional bank holdings and other miscellaneous equity funds at March 31, 2024. At December 31, 2023, the Company held $14.9 million in SBIC investments and $226 thousand in local and regional bank holdings and other miscellaneous equity funds. Gains on these equity funds were recognized as income in 2024 and 2023 in compliance with ASU 2016-01, which requires all equity securities to be measured at their fair value with changes in fair value being recognized through the statements of income.
