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 June 30, 2021 and December 31, 2020, 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.

Structured securities are shown separately in the table below, as they are not due at a single maturity date.

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 2020 Annual Report, allowances for credit losses on fixed maturity securities are recognized in investment related gains (losses), net on the condensed consolidated statements of income. For these securities, the net 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 AOCI. The following table presents the rollforward of the allowance for credit losses in fixed maturity securities by type for the six months ended June 30, 2021 and 2020 (dollars in millions):

Unrealized Losses for Fixed Maturity Securities Available-for-Sale The following table presents the total gross unrealized losses for the 1,223 and 877 fixed maturity securities as of June 30, 2021 and December 31, 2020, where the estimated fair value had declined and remained below amortized cost by the indicated amount (dollars in millions):
|  | June 30, 2021 |  | December 31, 2020
|  | Gross Unrealized Losses |  | % of Total |  | Gross Unrealized Losses |  | % of Total
Less than 20% |  | $ | 213 |  |  | 79.8 | % |  | $ | 133 |  |  | 67.5 | %

20% or more for six months or greater |  | 52 |  |  | 19.5 |  |  | 22 |  |  | 11.2 |
Total |  | $ | 267 |  |  | 100.0 | % |  | $ | 197 |  |  | 100.0 | %
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 values and gross unrealized losses for fixed maturity securities that have estimated fair values below amortized cost as of June 30, 2021 and December 31, 2020 (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 remained below amortized cost.

The Company has no intention to sell, nor does it expect to be required to sell, the securities outlined in the tables above, as of the dates indicated. 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. Changes in unrealized losses are primarily driven by changes in interest rates. Investment Income and Investment Related Gains (Loss), Net – Accounting Correction During the first quarter of 2021, the Company reclassified approximately $92 million of pre-tax unrealized gains from AOCI to investment income, net of related expenses associated with investments in limited partnerships and private equity funds for which it utilizes the equity method of accounting. The unrealized gains should have been recognized directly in investment income in the same prior periods they were reported by the investees. In addition, the Company recorded approximately $70 million of pre-tax gains in investment related gains (losses), net, associated with investments in limited partnerships considered to be investment companies in order to adjust the carrying value from cost less impairments to a fair value approach, using the net asset value (“NAV”) per share or its equivalent. Had the adjustments been recorded in the years they were reported by the investees, the Company estimates it would have recognized approximately $102 million, $(2) million, $1 million and $10 million of pre-tax income (loss) in the years ended December 31, 2020, 2019, 2018 and 2017, respectively.

(1)Average recorded investment represents the average loan balances as of the beginning of period and all subsequent quarterly end of period balances. The Company did not acquire any impaired mortgage loans during the six months ended June 30, 2021 and 2020. The Company had no mortgage loans that were on a nonaccrual status as of June 30, 2021 and December 31, 2020. During the six months ended June 30, 2021, the Company modified the payment terms of one commercial mortgage loan, with a carrying value of approximately $10 million in response to COVID-19. During the year ended December 31, 2020, the Company modified the payment terms of 52 commercial mortgage loans, with a carrying value of approximately $660 million in response to COVID-19. These loans met the criteria established in the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) and were not considered a troubled debt restructuring. In accordance with the CARES Act criteria, these loans were not more than 30 days past due at December 31, 2019, and the modifications included deferral or delayed payments of principal or interest on the loan. 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 June 30, 2021, $4.7 billion of the funds withheld at interest balance is associated with two clients. For reinsurance agreements written on 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, derivative contracts and fair value option (“FVO”) contractholder-directed unit-linked investments. Other invested assets also include FHLB common stock, which is included in Other in the table below. The allowance for credit losses for lifetime mortgages as of June 30, 2021 and December 31, 2020, was $1 million and $2 million, respectively. Carrying values of these assets as of June 30, 2021 and December 31, 2020 are as follows (dollars in millions):
|  | June 30, 2021 |  | December 31, 2020
