Investment Risks and Uncertainties
Investments are exposed to the following primary sources of risk: credit, interest rate, liquidity, market valuation, currency and real estate risk. The financial statement risks, stemming from such investment risks, are those associated with the determination of estimated fair values, the diminished ability to sell certain investments in times of strained market conditions, the recognition of ACL and impairments, the recognition of income on certain investments and the potential consolidation of VIEs. The use of different methodologies, assumptions and inputs relating to these financial statement risks may have a material effect on the amounts presented within the consolidated financial statements.
The determination of ACL and impairments is highly subjective and is based upon quarterly evaluations and assessments of known and inherent risks associated with the respective asset class. Such evaluations and assessments are revised as conditions change and new information becomes available.
The recognition of income on certain investments (e.g. structured securities, including mortgage-backed securities, asset-backed securities and collateralized loan obligations (“ABS & CLO”), certain structured investment transactions and FVO securities) is dependent upon certain factors such as prepayments and defaults, and changes in such factors could result in changes in amounts to be earned.

Methodology for Amortization of Premium and Accretion of Discount on Structured Products
Amortization of premium and accretion of discount on Structured Products considers the estimated timing and amount of prepayments of the underlying loans. Actual prepayment experience is periodically reviewed and effective yields are recalculated when differences arise between the originally anticipated and the actual prepayments received and currently anticipated. Prepayment assumptions for Structured Products are estimated using inputs obtained from third-party specialists and based on management’s knowledge of the current market. For credit-sensitive and certain prepayment-sensitive Structured Products, the effective yield is recalculated on a prospective basis. For all other Structured Products, the effective yield is recalculated on a retrospective basis.

Evaluation of Fixed Maturity Securities AFS for Credit Loss
Evaluation and Measurement Methodologies
Management considers a wide range of factors about the security issuer and uses its best judgment in evaluating the cause of the decline in the estimated fair value of the security and in assessing the prospects for near-term recovery. Inherent in management’s evaluation of the security are assumptions and estimates about the operations of the issuer and its future earnings potential. Considerations used in the credit loss evaluation process include, but are not limited to: (i) the extent to which the estimated fair value has been below amortized cost, (ii) adverse conditions specifically related to a security, an industry sector or sub-sector, or an economically depressed geographic area, adverse change in the financial condition of the issuer of the security, changes in technology, discontinuance of a segment of the business that may affect future earnings, and changes in the quality of credit enhancement, (iii) payment structure of the security and likelihood of the issuer being able to make payments, (iv) failure of the issuer to make scheduled interest and principal payments, (v) whether the issuer, or series of issuers or an industry has suffered a catastrophic loss or has exhausted natural resources, (vi) whether the Company has the intent to sell or will more likely than not be required to sell, including transfers in connection with reinsurance transactions, a particular security before the decline in estimated fair value below amortized cost recovers, (vii) with respect to Structured Products, changes in forecasted cash flows after considering the changes in the financial condition of the underlying loan obligors and quality of underlying collateral, expected prepayment speeds, current and forecasted loss severity, consideration of the payment terms of the underlying assets backing a particular security, and the payment priority within the tranche structure of the security, (viii) changes in the rating of the security by a rating agency, and (ix) other subjective factors, including concentrations and information obtained from regulators.
The methodology and significant inputs used to determine the amount of credit loss are as follows:
The Company calculates the recovery value by performing a discounted cash flow analysis based on the present value of future cash flows. The discount rate is generally the effective interest rate of the security at the time of purchase for fixed-rate securities and the spot rate at the date of evaluation of credit loss for floating-rate securities.
When determining collectability and the period over which value is expected to recover, the Company applies considerations utilized in its overall credit loss evaluation process which incorporates information regarding the specific security, fundamentals of the industry and geographic area in which the security issuer operates, and overall macroeconomic conditions. Projected future cash flows are estimated using assumptions derived from management’s single best estimate, the most likely outcome in a range of possible outcomes, after giving consideration to a variety of variables that include, but are not limited to: payment terms of the security; the likelihood that the issuer can service the interest and principal payments; the quality and amount of any credit enhancements; the security’s position within the capital structure of the issuer; possible corporate restructurings or asset sales by the issuer; any private and public sector programs to restructure foreign government securities and municipals; and changes to the rating of the security or the issuer by rating agencies.
Additional considerations are made when assessing the features that apply to certain Structured Products including, but not limited to: the quality of underlying collateral, historical performance of the underlying loan obligors, historical rent and vacancy levels, changes in the financial condition of the underlying loan obligors, expected prepayment speeds, current and forecasted loss severity, consideration of the payment terms of the underlying loans or assets backing a particular security, changes in the quality of credit enhancement and the payment priority within the tranche structure of the security.
With respect to securities that have attributes of debt and equity (“perpetual hybrid securities”), consideration is given in the credit loss analysis as to whether there has been any deterioration in the credit of the issuer and the likelihood of recovery in value of the securities that are in a severe unrealized loss position. Consideration is also given as to whether any perpetual hybrid securities with an unrealized loss, regardless of credit rating, have deferred any dividend payments.
In periods subsequent to the recognition of an initial ACL on a security, the Company reassesses credit loss quarterly. Subsequent increases or decreases in the expected cash flow from the security result in corresponding decreases or increases in the ACL which are recognized in earnings and reported within net investment gains (losses); however, the previously recorded ACL is not reduced to an amount below zero. Full or partial write-offs are deducted from the ACL in the period the security, or a portion thereof, is considered uncollectible. Recoveries of amounts previously written off are recorded to the ACL in the period received. When the Company has the intent-to-sell the security or it is more likely than not that the Company will be required to sell the security before recovery of its amortized cost, any ACL is written off and the amortized cost is written down to estimated fair value through a charge within net investment gains (losses), which becomes the new amortized cost of the security.
Evaluation of Fixed Maturity Securities AFS in an Unrealized Loss Position
Gross unrealized losses on securities without an ACL decreased $8.5 billion for the year ended December 31, 2023 to $25.8 billion primarily due to interest rate volatility, narrowing credit spreads, impairments in connection with a reinsurance transaction and, to a lesser extent, the strengthening of foreign currencies on certain non-functional currency denominated fixed maturity securities.
As shown above, most of the gross unrealized losses on securities without an ACL that have been in a continuous gross unrealized loss position for 12 months or greater at December 31, 2023 relate to investment grade securities. These unrealized losses are principally due to widening credit spreads since purchase and, with respect to fixed-rate securities, rising interest rates since purchase.
As of December 31, 2023, $719 million of gross unrealized losses on securities without an ACL that have been in a continuous gross unrealized loss position for 12 months or greater on below investment grade securities were concentrated in the consumer, transportation, and communications sectors within corporate securities and in foreign government securities. These unrealized losses are the result of significantly wider credit spreads resulting from higher risk premiums since purchase, largely due to economic and market uncertainty and, with respect to fixed-rate securities, rising interest rates since purchase.
At December 31, 2023, the Company did not intend to sell its securities in an unrealized loss position without an ACL, and it was not more likely than not that the Company would be required to sell these securities before the anticipated recovery of the remaining amortized cost. Therefore, the Company concluded that these securities had not incurred a credit loss and should not have an ACL at December 31, 2023.
Future provisions for credit loss will depend primarily on economic fundamentals, issuer performance (including changes in the present value of future cash flows expected to be collected), changes in credit ratings and collateral valuation.

(1)Includes certain mortgage loans originated for third parties of $8.5 billion at amortized cost ($8.2 billion commercial and $246 million agricultural) and the related ACL of $73 million, with the corresponding mortgage loan secured financing liability of $8.5 billion included in other liabilities on the consolidated balance sheet. The investment income on these mortgage loans originated for third parties and the interest expense on the mortgage loan secured financing liability was $408 million for the year ended December 31, 2023, and recorded in investment income and investment expenses, within net investment income. See Note 1.
The amount of net (discounts) premiums and deferred (fees) expenses, included within total amortized cost, primarily attributable to residential mortgage loans was ($736) million and ($744) million at December 31, 2023 and 2022, respectively. The accrued interest income excluded from total amortized cost for commercial, agricultural and residential mortgage loans at December 31, 2023 was $277 million, $204 million, and $95 million, respectively. The accrued interest income excluded from total amortized cost for commercial, agricultural and residential mortgage loans at December 31, 2022 was $219 million, $176 million and $81 million, respectively.
Purchases of mortgage loans, consisting primarily of residential mortgage loans, were $1.5 billion, $3.1 billion and $1.8 billion for the years ended December 31, 2023, 2022 and 2021, respectively.
During the year ended December 31, 2023, the Company disposed of commercial mortgage loans with an amortized cost of $254 million in connection with a reinsurance transaction. The disposition resulted in a loss of $58 million for the year ended December 31, 2023.
During the years ended December 31, 2023 and 2022, the Company contributed commercial mortgage loans with an amortized cost of $15 million and $489 million, respectively, to joint ventures in anticipation of subsequent foreclosure or deed-in-lieu of foreclosure transactions. During the years ended December 31, 2023 and 2022, the joint ventures completed foreclosure or deed-in-lieu of foreclosure transactions on loans with an amortized cost of $37 million and $467 million, respectively. During the year ended December 31, 2023, no gains or losses were recognized on foreclosures or deed-in-lieu of foreclosures within joint ventures as the estimated fair value of the real estate collateralizing the foreclosures or deed-in-lieu of foreclosures approximated amortized cost. The real estate collateralizing the 2022 foreclosures or deed-in-lieu of foreclosures had an estimated fair value in excess of amortized cost. Therefore, during the year ended December 31, 2022, the Company recognized its pro rata share of $34 million within net investment gains (losses) upon consummation of the foreclosures or deed-in-lieu of foreclosures. See “— Real Estate and Real Estate Joint Ventures” for the carrying value of wholly-owned real estate acquired through foreclosure.

Allowance for Credit Loss Methodology
The Company records an allowance for expected lifetime credit loss in earnings within net investment gains (losses) in an amount that represents the portion of the amortized cost basis of mortgage loans that the Company does not expect to collect, resulting in mortgage loans being presented at the net amount expected to be collected. In determining the Company’s ACL, management applies significant judgment to estimate expected lifetime credit loss, including: (i) pooling mortgage loans that share similar risk characteristics, (ii) considering expected lifetime credit loss over the contractual term of its mortgage loans adjusted for expected prepayments and any extensions, and (iii) considering past events and current and forecasted economic conditions. Each of the Company’s commercial, agricultural and residential mortgage loan portfolio segments are evaluated separately. The ACL is calculated for each mortgage loan portfolio segment based on inputs unique to each loan portfolio segment. On a quarterly basis, mortgage loans within a portfolio segment that share similar risk characteristics, such as internal risk ratings or consumer credit scores, are pooled for calculation of ACL. On an ongoing basis, mortgage loans with dissimilar risk characteristics (i.e., loans with significant declines in credit quality), such as collateral dependent mortgage loans (i.e., when the borrower is experiencing financial difficulty, including when foreclosure is reasonably possible or probable), are evaluated individually for credit loss. The ACL for loans evaluated individually are established using the same methodologies for all three portfolio segments. For example, the ACL for a collateral dependent loan is established as the excess of amortized cost over the estimated fair value of the loan’s underlying collateral, less selling cost when foreclosure is probable. Accordingly, the change in the estimated fair value of collateral dependent loans, which are evaluated individually for credit loss, is recorded as a change in the ACL which is recorded on a quarterly basis as a charge or credit to earnings in net investment gains (losses).
Commercial and Agricultural Mortgage Loan Portfolio Segments
Within each loan portfolio segment, commercial and agricultural loans are pooled by internal risk rating. Estimated lifetime loss rates, which vary by internal risk rating, are applied to the amortized cost of each loan, excluding accrued investment income, on a quarterly basis to develop the ACL. Internal risk ratings are based on an assessment of the loan’s credit quality, which can change over time. The estimated lifetime loss rates are based on several loan portfolio segment-specific factors, including (i) the Company’s experience with defaults and loss severity, (ii) expected default and loss severity over the forecast period, (iii) current and forecasted economic conditions including growth, inflation, interest rates and unemployment levels, (iv) loan specific characteristics including loan-to-value (“LTV”) ratios, and (v) internal risk ratings. These evaluations are revised as conditions change and new information becomes available. The Company uses its several decades of historical default and loss severity experience which capture multiple economic cycles. The Company uses a forecast of economic assumptions for a two-year period for most of its commercial and agricultural mortgage loans, while a one-year period is used for loans originated in certain markets. After the applicable forecast period, the Company reverts to its historical loss experience using a straight-line basis over two years. For evaluations of commercial mortgage loans, in addition to historical experience, management considers factors that include the impact of a rapid change to the economy, which may not be reflected in the loan portfolio, recent loss and recovery trend experience as compared to historical loss and recovery experience, and loan specific characteristics including debt service coverage ratios (“DSCR”). In estimating expected lifetime credit loss over the term of its commercial mortgage loans, the Company adjusts for expected prepayment and extension experience during the forecast period using historical prepayment and extension experience considering the expected position in the economic cycle and the loan profile (i.e., floating rate, shorter-term fixed rate and longer-term fixed rate) and after the forecast period using long-term historical prepayment experience. For evaluations of agricultural mortgage loans, in addition to historical experience, management considers factors that include increased stress in certain sectors, which may be evidenced by higher delinquency rates, or a change in the number of higher risk loans. In estimating expected lifetime credit loss over the term of its agricultural mortgage loans, the Company’s experience is much less sensitive to the position in the economic cycle and by loan profile; accordingly, historical prepayment experience is used, while extension terms are not prevalent with the Company’s agricultural mortgage loans.
Commercial mortgage loans are reviewed on an ongoing basis, which review includes, but is not limited to, an analysis of the property financial statements and rent roll, lease rollover analysis, property inspections, market analysis, estimated valuations of the underlying collateral, LTV ratios, DSCR and tenant creditworthiness. The monitoring process focuses on higher risk loans, which include those that are classified as restructured, delinquent or in foreclosure, as well as loans with higher LTV ratios and lower DSCR. Agricultural mortgage loans are reviewed on an ongoing basis, which review includes, but is not limited to, property inspections, market analysis, estimated valuations of the underlying collateral, LTV ratios and borrower creditworthiness, as well as reviews on a geographic and property-type basis. The monitoring process for agricultural mortgage loans also focuses on higher risk loans.
For commercial mortgage loans, the primary credit quality indicator is the DSCR, which compares a property’s net operating income to amounts needed to service the principal and interest due under the loan. Generally, the lower the DSCR, the higher the risk of experiencing a credit loss. The Company also reviews the LTV ratio of its commercial mortgage loan portfolio. LTV ratios compare the unpaid principal balance of the loan to the estimated fair value of the underlying collateral. Generally, the higher the LTV ratio, the higher the risk of experiencing a credit loss. The DSCR and the values utilized in calculating the ratio are updated routinely. In addition, the LTV ratio is routinely updated for all but the lowest risk loans as part of the Company’s ongoing review of its commercial mortgage loan portfolio.
For agricultural mortgage loans, the Company’s primary credit quality indicator is the LTV ratio. The values utilized in calculating this ratio are developed in connection with the ongoing review of the agricultural mortgage loan portfolio and are routinely updated.
After commercial and agricultural mortgage loans are approved, the Company makes commitments to lend and, typically, borrowers draw down on some or all of the commitments. The timing of mortgage loan funding is based on the commitment expiration dates. A liability for credit loss for unfunded commercial and agricultural mortgage loan commitments that is not unconditionally cancellable is recognized in earnings and is reported within net investment gains (losses). The liability is based on estimated lifetime loss rates as described above and the amount of the outstanding commitments, which for lines of credit, considers estimated utilization rates. When the commitment is funded or expires, the liability is adjusted accordingly.
Residential Mortgage Loan Portfolio Segment
The Company’s residential mortgage loan portfolio is comprised primarily of purchased closed end, amortizing residential mortgage loans, including both performing loans purchased within 12 months of origination and reperforming loans purchased after they have been performing for at least 12 months post-modification. Residential mortgage loans are pooled by loan type (i.e., new origination and reperforming) and pooled by similar risk profiles (including consumer credit score and LTV ratios). Estimated lifetime loss rates, which vary by loan type and risk profile, are applied to the amortized cost of each loan excluding accrued investment income on a quarterly basis to develop the ACL. The estimated lifetime loss rates are based on several factors, including (i) industry historical experience and expected results over the forecast period for defaults, (ii) loss severity, (iii) prepayment rates, (iv) current and forecasted economic conditions including growth, inflation, interest rates and unemployment levels, and (v) loan pool specific characteristics including consumer credit scores, LTV ratios, payment history and home prices. These evaluations are revised as conditions change and new information becomes available. The Company uses industry historical experience which captures multiple economic cycles as the Company has purchased most of its residential mortgage loans in the last five years. The Company uses a forecast of economic assumptions for a two-year period for most of its residential mortgage loans. After the applicable forecast period, the Company reverts to industry historical loss experience using a straight-line basis over one year.
For residential mortgage loans, the Company’s primary credit quality indicator is whether the loan is performing or nonperforming. The Company generally defines nonperforming residential mortgage loans as those that are 60 or more days past due and/or in nonaccrual status which is assessed monthly. Generally, nonperforming residential mortgage loans have a higher risk of experiencing a credit loss.
Modifications to Borrowers Experiencing Financial Difficulty
The Company may modify mortgage loans to borrowers. Each mortgage loan modification is evaluated to determine whether the borrower was experiencing financial difficulties. Disclosed below are those modifications, in materially impacted segments, where the borrower was determined to be experiencing financial difficulties and the mortgage loans were modified by any of the following means, principal forgiveness, interest rate reduction, other-than-insignificant payment delay or term extension. The amount, timing and extent of modifications granted are considered in determining any ACL recorded. Mortgage loans are summarized as follows at:

Leases
Leased Real Estate Investments - Operating Leases
The Company, as lessor, leases investment real estate, principally commercial real estate for office and retail use, through a variety of operating lease arrangements, which typically include tenant reimbursement for property operating costs and options to renew or extend the lease. In some circumstances, leases may include an option for the lessee to purchase the property. In addition, certain leases of retail space may stipulate that a portion of the income earned is contingent upon the level of the tenants’ revenues. The Company has elected a practical expedient of not separating non-lease components related to reimbursement of property operating costs from associated lease components. These property operating costs have the same timing and pattern of transfer as the related lease component, because they are incurred over the same period of time as the operating lease. Therefore, the combined component is accounted for as a single operating lease. Risk is managed through lessee credit analysis, property type diversification, and geographic diversification. Leased real estate investments and income earned, by property type, were as follows at and for the periods indicated:

See “— Securities Lending Transactions and Repurchase Agreements” for information regarding securities supporting securities lending transactions and repurchase agreements and Note 10 for information regarding investments designated to the closed block. In addition, the Company’s investment in FHLBNY common stock, included within other invested assets, which is considered restricted until redeemed by the issuer, was $714 million and $729 million, at redemption value, at December 31, 2023 and 2022, respectively.
Collectively Significant Equity Method Investments
The Company held equity method investments of $25.2 billion at December 31, 2023, comprised primarily of other limited partnership interests (private equity funds and hedge funds), real estate joint ventures (including real estate funds), tax credit and renewable energy partnerships and operating joint ventures. The Company’s maximum exposure to loss related to these equity method investments was limited to the carrying value of these investments plus $6.7 billion of unfunded commitments at December 31, 2023.
As described in Note 1, the Company generally recognizes its share of earnings in its equity method investments within net investment income using a three-month lag in instances where the investee’s financial information is not sufficiently timely or when the investee’s reporting period differs from the Company’s reporting period. Aggregate net investment income from these equity method investments exceeded 10% of the Company’s consolidated pre-tax income (loss) for two of the three most recent annual periods: 2022 and 2021.
The following aggregated summarized financial data reflects the latest available financial information and does not represent the Company’s proportionate share of the assets, liabilities, or earnings of such entities. Aggregate total assets of these entities totaled $1.2 trillion at both December 31, 2023 and 2022. Aggregate total liabilities of these entities totaled $148.0 billion and $148.9 billion at December 31, 2023 and 2022, respectively. Aggregate net income (loss) of these entities totaled $32.8 billion, ($11.8) billion and $231.0 billion for the years ended December 31, 2023, 2022 and 2021, respectively. Aggregate net income (loss) from the underlying entities in which the Company invests is primarily comprised of investment income, including recurring investment income (loss) and realized and unrealized investment gains (losses).
Variable Interest Entities
The Company has invested in legal entities that are VIEs. In certain instances, the Company holds both the power to direct the most significant activities of the entity, as well as an economic interest in the entity and, as such, is deemed to be the primary beneficiary or consolidator of the entity. The determination of the VIE’s primary beneficiary requires an evaluation of the contractual and implied rights and obligations associated with each party’s relationship with or involvement in the entity.
Consolidated VIEs
Creditors or beneficial interest holders of VIEs where the Company is the primary beneficiary have no recourse to the general credit of the Company, as the Company’s obligation to the VIEs is limited to the amount of its committed investment.
The following table presents the total assets and total liabilities relating to investment related VIEs for which the Company has concluded that it is the primary beneficiary and which are consolidated at:

(1)The maximum exposure to loss relating to fixed maturity securities AFS and FVO securities is equal to their carrying amounts or the carrying amounts of retained interests. The maximum exposure to loss relating to other limited partnership interests (“OLPI”) and real estate joint ventures (“REJV”) is equal to the carrying amounts plus any unfunded commitments. For certain of its investments in other invested assets, the Company’s return is in the form of income tax credits which are guaranteed by creditworthy third parties. For such investments, the maximum exposure to loss is equal to the carrying amounts plus any unfunded commitments, reduced by income tax credits guaranteed by third parties. Such a maximum loss would be expected to occur only upon bankruptcy of the issuer or investee.
(2)For variable interests in Structured Products included within fixed maturity securities AFS, the Company’s involvement is limited to that of a passive investor in mortgage-backed or asset-backed securities issued by trusts that do not have substantial equity.
In connection with the reinsurance transaction with subsidiaries of Global Atlantic Financial Group, collateral securing the reinsurance transaction was transferred to trusts that do not have substantial equity. The Company does not have a carrying amount related to the trusts but does manage a portion of the invested assets. For managing these assets, the Company will receive an investment management fee which represents a variable interest. The Company’s maximum exposure to loss is limited to the investment management fee revenue that has been earned but not yet received. See Note 9 for further information on this reinsurance transaction.
As described in Note 24, the Company makes commitments to fund partnership investments in the normal course of business. Excluding these commitments, the Company did not provide financial or other support to investees designated as VIEs for each of the years ended December 31, 2023, 2022 and 2021
