The Company enters into various collateral arrangements with counterparties that require both the pledging and acceptance of fixed maturity securities as collateral. Pledged fixed maturity securities are included in fixed maturity securities available-for-sale in the condensed consolidated balance sheets. Fixed maturity securities received as collateral are held in separate custodial accounts and are not recorded on the Company’s condensed consolidated balance sheets. Subject to certain constraints, the Company is permitted by contract to sell or repledge collateral it receives; however, as of March 31, 2022 and December 31, 2021, none of the collateral received had been sold or repledged. The Company also holds assets in trust to satisfy collateral requirements under derivative transactions and certain third-party reinsurance treaties. The following table includes fixed maturity securities pledged and received as collateral and assets in trust held to satisfy collateral requirements under derivative transactions and certain third-party reinsurance treaties as of March 31, 2022 and December 31, 2021 (dollars in millions):

Allowance for Credit Losses and Impairments – Fixed Maturity Securities Available-for-Sale As discussed in Note 2 – “Significant Accounting Policies and Pronouncements” of the Company’s 2021 Annual Report, allowances for credit losses on fixed maturity securities are recognized in investment related gains (losses), net. The amount recognized represents the difference between the amortized cost of the security and the net present value of its projected future cash flows discounted at the effective interest rate implicit in the fixed maturity security prior to the allowance for credit losses. Any remaining difference between the fair value and amortized cost is recognized in OCI. The following tables present the rollforward of the allowance for credit losses in fixed maturity securities by type for the three months ended March 31, 2022 and 2021 (dollars in millions):

Unrealized Losses for Fixed Maturity Securities Available-for-Sale The Company’s determination of whether a decline in value necessitates the recording of an allowance for credit losses includes an analysis of whether the issuer is current on its contractual payments, evaluating whether it is probable that the Company will be able to collect all amounts due according to the contractual terms of the security and analyzing the overall ability of the Company to recover the amortized cost of the investment. The following tables present the estimated fair value and gross unrealized losses for the 4,136 and 1,862 fixed maturity securities for which an allowance for credit loss has not been recorded as of March 31, 2022 and December 31, 2021, and the estimated fair value had declined and remained below amortized cost (dollars in millions). These investments are presented by class and grade of security, as well as the length of time the related fair value has continuously remained below amortized cost.

However, unforeseen facts and circumstances may cause the Company to sell fixed maturity securities in the ordinary course of managing its portfolio to meet certain diversification, credit quality and liquidity guidelines.

For the three months ended March 31, 2022, the Company restructured three mortgage loans to interest only payments as a result of lower occupancy levels. The total recorded investment before allowance for credit losses for mortgage loans, which were modified and met the criteria of Troubled Debt Restructuring (“TDR”), is $77 million as of March 31, 2022. For the three months ended March 31, 2021, the Company did not have any significant loans that were modified and met the criteria of a TDR. The Company had no mortgage loans that were on a nonaccrual status as of March 31, 2022 and 2021. The Company did not acquire any impaired mortgage loans during three months ended March 31, 2022 and 2021. Policy Loans The majority of policy loans are associated with one client. These policy loans present no credit risk as the amount of the loan cannot exceed the obligation due to the ceding company upon the death of the insured or surrender of the underlying policy. The provisions of the treaties in force and the underlying policies determine the policy loan interest rates. The Company earns a spread between the interest rate earned on policy loans and the interest rate credited to corresponding liabilities. Funds Withheld at Interest As of March 31, 2022, $4.4 billion of the funds withheld at interest balance is primarily associated with two clients. For reinsurance agreements written on a modco basis and certain agreements written on a coinsurance funds withheld basis, assets equal to the net statutory reserves are withheld and legally owned and managed by the ceding company and are reflected as funds withheld at interest. In the event of a ceding company’s insolvency, the Company would need to assert a claim on the assets supporting its reserve liabilities. However, the risk of loss to the Company is mitigated by its ability to offset amounts it owes the ceding company for claims or allowances against amounts owed to the Company from the ceding company. Other Invested Assets Other invested assets include limited partnership interests, joint ventures (other than operating joint ventures), lifetime mortgages, and derivative contracts. Other invested assets also includes FHLB common stock and unit-linked investments, which are included in Other in the table below. As of March 31, 2022 and December 31, 2021, the allowance for credit losses for lifetime mortgages was not material. The carrying values of other invested assets as of March 31, 2022 and December 31, 2021 are as follows (dollars in millions):
|  | March 31, 2022 |  | December 31, 2021
