The Company has evaluated AFS securities in an unrealized loss position for credit related impairment at September 30, 2023 and December 31, 2022 and concluded no impairment existed based on several factors which included: (1) the majority of these securities are of high credit quality, (2) unrealized losses are primarily the result of market volatility and increases in market interest rates, (3) the contractual terms of the investments do not permit the issuer(s) to settle the securities at a price less than the cost basis of each investment, (4) issuers continue to make timely principal and interest payments, and (5) the Company does not intend to sell any of the investments and the accounting standard of “more likely than not” has not been met for the Company to be required to sell any of the investments before recovery of its amortized cost basis.

Additionally, the majority of the Company’s MBS are issued by FNMA, FHLMC, and GNMA and do not have credit risk given the implicit and explicit government guarantees associated with these agencies. In addition, the non-agency mortgage-backed and asset-backed securities generally received a 20% simplified supervisory formula approach rating.

The following table presents the amortized cost and estimated fair value of AFS securities as of September 30, 2023 and December 31, 2022, by contractual maturity (dollars in thousands). Expected maturities may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.

Credit Quality Indicators & Allowance for Credit Losses HTM

For HTM securities, the Company evaluates the credit risk of its securities on at least a quarterly basis. The Company estimates expected credit losses on HTM debt securities on an individual basis based on the PD/LGD methodology primarily using security-level credit ratings. The Company’s HTM securities ACL was insignificant at September 30, 2023 and December 31, 2022. The primary indicators of credit quality for the Company’s HTM portfolio are security type and credit rating, which is influenced by a number of factors including obligor cash flow, geography, seniority, and others. The majority of the Company’s HTM securities with credit risk are obligations of states and political subdivisions.

The following table presents the amortized cost of HTM securities as of September 30, 2023 and December 31, 2022 by security type and credit rating (dollars in thousands):
