Marketable securities are composed of available-for-sale debt securities and marketable equity securities and all marketable securities are held at fair value. We carry a portion of our marketable securities portfolio in long-term assets since they are generally held for the settlement of our insurance claims processed through our wholly owned captive insurance subsidiary.

Available-for-sale debt securities are included in other current assets and marketable securities and other investments totaling $37,062 and $25,518 at December 31, 2023 and December 31, 2022, respectively. Realized gains and losses on sales of available-for-sale debt securities are recognized in net income on the specific identification basis. Changes in the fair values of available-for-sale debt securities that are determined to be holding gains or losses are recorded through accumulated other comprehensive income (loss) net of applicable taxes, within shareholders' equity. In assessing whether a credit loss exists, we evaluate our ability to hold the investment, the strength of the underlying collateral and the extent to which the investment's amortized cost or cost, as appropriate, exceeds its related fair value.

As of December 31, 2023 and December 31, 2022 we held approximately $12,102 and $18,110 in marketable equity securities, respectively. Realized and unrealized gains and losses on marketable equity securities are included in other income (expense) in the Consolidated Statements of Operations.

The net carrying values of available-for-sale debt securities at December 31, 2023 by contractual maturity, are shown below. Expected maturities may differ from contractual maturities because the issuers of the securities may have the right to prepay obligations without prepayment penalties.
