The amortized cost and estimated fair value of debt securities available-for-sale and held-to-maturity as of September 30, 2024, by contractual maturity are shown below. Maturities may differ from contractual maturities in mortgage-backed securities because the mortgages underlying these securities may be called or repaid without penalty. Therefore, these securities are not included in the maturity categories in the following maturity summary:

As of September 30, 2024, the Company’s held-to-maturity security portfolio consisted of 35 securities, 28 of which were in an unrealized loss position. At September 30, 2024, the Company held 20 mortgage-backed securities and eight state, county and municipal securities that were in an unrealized loss position.

At September 30, 2024 and December 31, 2023, all of the Company’s mortgage-backed securities were obligations of government-sponsored agencies.

Management and the Company’s Asset and Liability Committee (the “ALCO Committee”) evaluate available-for-sale securities in an unrealized loss position on at least a quarterly basis, and more frequently when economic or market concerns warrant such evaluation, to determine if credit-related impairment exists. Management first evaluates whether they intend to sell or more likely than not will be required to sell an impaired security before recovering its amortized cost basis. If either criteria is met, the entire amount of unrealized loss is recognized in earnings with a corresponding adjustment to the security's amortized cost basis. If either of the above criteria is not met, management evaluates whether the decline in fair value is attributable to credit or resulted from other factors. The Company does not intend to sell these available-for-sale investment securities at an unrealized loss position at September 30, 2024, and it is more likely than not that the Company will not be required to sell these securities prior to recovery or maturity. Based on the results of management's review, at September 30, 2024, management determined that $66,000 was attributable to credit impairment and an allowance for credit losses was recorded. The remaining $24.4 million in unrealized loss was determined to be from factors other than credit.
