(1) Other bonds include asset-backed securities.

(2) Comprised of 363 and 33 individual securities as of December 31, 2022 and December 31, 2021, respectively.

The Company has evaluated AFS securities in an unrealized loss position for credit related impairment at December 31, 2022 and 2021 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 December 31, 2022 and 2021, 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.

Held to Maturity

The Company’s HTM investment portfolio primarily consists of highly-rated municipal securities. The Company’s HTM securities were all current, with no securities past due or on non-accrual at December 31, 2022 and 2021.

The Company reports HTM securities on the Company’s Consolidated Balance Sheets at carrying value. Carrying value is amortized cost, which includes any unamortized unrealized gains and losses recognized in AOCI prior to reclassifying the securities from AFS securities to HTM securities. Investment securities transferred into the HTM category from the AFS category are recorded at fair value at the date of transfer. The unrealized holding gains or losses at the date of transfer are retained in AOCI and in the carrying value of the HTM securities. Such unrealized gains or losses are accreted over the remaining life of the security with no impact on future net income.

The carrying value, gross unrealized gains and losses, and estimated fair values of HTM securities as of December 31, 2022 are summarized as follows (dollars in thousands):

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 immaterial at December 31, 2022 and 2021. 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.
