The following tables present fair value and gross unrealized losses, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position, as of the dates stated. The reference point for determining when securities are in an unrealized loss position is period-end; therefore, it is possible that a security's market value exceeded its amortized cost on other days during the past twelve-month period. Excluded from the tables below were securities whose amortized cost equaled their fair value or were in an unrealized gain position as of the dates stated totaling $1.1 million and $4.4 million, as of December 31, 2024 and 2023, respectively.

At December 31, 2024 and 2023, the majority of securities in an unrealized loss position were of investment grade; however, a portion of the portfolio does not have a third-party investment grade available (securities with fair values of of $29.3 million and $20.5 million, respectively). These securities were primarily subordinated debt instruments issued by bank holding companies and are classified as corporate bonds in the tables above. The Company evaluated the issuers of these individually, observing that each issuer had strong capital ratios and profitability thereby indicating limited exposure to asset quality or liquidity issues, which resulted in no identifiable credit losses. Contractual cash flows for mortgage backed securities and U.S. Treasury and agencies are guaranteed and/or funded by the U.S. government and government agencies. State and municipal securities showed no indication that the contractual cash flows would not be received when due. The Company does not intend to sell, nor does it believe that it will be required to sell, any of its impaired securities prior to the recovery of the amortized cost. As of December 31, 2024 and 2023, there was no ACL for the Company's securities AFS portfolio. Any impairment that has not been recorded through an ACL is recognized in accumulated other comprehensive income (loss).

Restricted equity investments consisted of stock in the FHLB (carrying basis $9.4 million and $12.3 million at December 31, 2024 and 2023, respectively), FRB stock (carrying basis of $9.4 million and $5.9 million at December 31, 2024 and 2023), respectively, and stock in the Company’s correspondent bank (carrying basis of $468 thousand at both December 31, 2024 and 2023). Restricted equity investments are carried at cost.

The Company has various other equity investments, including investments in a fintech company and limited partnerships, totaling $4.8 million and $12.9 million as of December 31, 2024 and 2023, respectively. In the second quarter of 2024, the Company identified potential impairment triggers related to one of its investments, mainly due to regulatory pressures on banks partnering with fintech companies in the banking-as-a-service sector. These pressures led some fintech companies to announce cost-saving measures and at least one to seek bankruptcy protection. As a result, the Company engaged a third-party valuation firm to value the Company's investment in a fintech company. This valuation resulted in an $8.5 million impairment charge to adjust the investment to its estimated fair market value recorded in fair value adjustments of other equity investments in the consolidated statement of operations.

As of December 31, 2024, the Company held investments in early-stage focused investment funds and low-income housing partnerships, which totaled $19.4 million.

These investments are reported in other investments on the consolidated balance sheets. The Company sold all of its SBIC investments ($11.9 million) during 2024 for a $139 thousand net gain, which is reported in other noninterest income in the consolidated statement of operations.
