The changes in fair value of embedded derivatives are reported in Net gains (losses) in the Condensed Consolidated Statements of Operations. The amortized cost and fair value of fixed maturities, including securities pledged, as of June 30, 2024, are shown below by contractual maturity. Actual maturities may differ from contractual maturities as securities may be restructured, called or prepaid. Mortgage-backed securities ("MBS") and Other asset-backed securities ("ABS") are shown separately because they are not due at a single maturity date.

As of June 30, 2024 and December 31, 2023, the Company did not have any investments in a single issuer, other than obligations of the U.S. Government and government agencies, with a carrying value in excess of 10% of the Company’s Total shareholders' equity. Repurchase Agreements and Securities Pledged As of June 30, 2024 and December 31, 2023, the Company did not have any securities pledged in dollar rolls or reverse repurchase agreements. The Company engages in securities lending whereby the initial collateral is required at a rate of at least 102% of the market value of the loaned securities. The lending agent retains the collateral and invests it in high quality liquid assets on behalf of the Company. The market value of the loaned securities is monitored on a daily basis with additional collateral obtained or refunded as the market value of the loaned securities fluctuates. The lending agent indemnifies the Company against losses resulting from the failure of a counterparty to return securities pledged where collateral is insufficient to cover the loss. In the normal course of business, the Company receives cash collateral and non-cash collateral in the form of securities. If cash is received as collateral, the lending agent retains the cash collateral and invests it in short-term liquid assets on behalf of the Company. Securities retained as collateral by the lending agent may not be sold or re-pledged, except in the event of default, and are not reflected on the Company’s Condensed Consolidated Balance Sheets. This collateral generally consists of U.S. Treasury, U.S. Government agency securities and MBS pools. The following table presents Securities pledged as of the dates indicated:

As of June 30, 2024, the average duration of our fixed maturities portfolio, including securities pledged, is between 6 and 6.5 years. As of June 30, 2024 and December 31, 2023, the Company concluded that an allowance for credit losses was not warranted for the securities above because the unrealized losses are interest rate related. The Company does not intend to sell the investments and it is not more likely than not that the Company will be required to sell the investments before recovery of their amortized cost bases. Evaluating Securities for Impairments The Company performs a regular evaluation, on a security-by-security basis, of its available-for-sale securities holdings, including fixed maturity securities, in accordance with its impairment policy in order to evaluate whether such investments are impaired. There were $5 intent impairments for the three and six months ended June 30, 2024 and $7 for the three and six months ended June 30, 2023. The Company may sell securities during the period in which fair value has declined below amortized cost for fixed maturities. In certain situations, new factors, including changes in the business environment, can change the Company’s previous intent to continue holding a security. Accordingly, these factors may lead the Company to record additional intent related capital losses. Debt Modifications The Company evaluates all debt modifications to determine whether a modification results in a new loan or a continuation of an existing loan. Disclosures are required for loan modifications with borrowers experiencing financial difficulty. For the three and six months ended June 30, 2024 and 2023, the Company had no material debt modifications that require such disclosure. Mortgage Loans on Real Estate The Company diversifies its commercial mortgage loan portfolio by geographic region and property type to reduce concentration risk. The Company manages risk when originating commercial mortgage loans by generally lending only up to 75% of the estimated fair value of the underlying real estate. Subsequently, the Company continuously evaluates mortgage loans based on relevant current information including a review of loan-specific performance, property characteristics and market trends. Loan performance is monitored on a loan specific basis through the review of submitted appraisals, operating statements, rent revenues and annual inspection reports, among other items. This review ensures properties are performing at a consistent and acceptable level to secure the debt. The components to evaluate debt service coverage are received and reviewed at least annually to determine the level of risk. Loan-to-value ("LTV") and debt service coverage ("DSC") ratios are measures commonly used to assess the risk and quality of mortgage loans. These ratios are utilized as part of the review process described above. The following tables present commercial mortgage loans by year of origination and LTV ratio as of the dates indicated. The information is updated as of June 30, 2024 and December 31, 2023, respectively.
