Evaluation of Fixed Maturity Securities AFS for Credit Loss Evaluation and Measurement Methodologies See Note 11 of the Notes to the Consolidated Financial Statements included in the 2023 Annual Report for a description of the Company’s Evaluation and Measurement Methodologies of Fixed Maturity Securities AFS for Credit Loss. Evaluation of Fixed Maturity Securities AFS in an Unrealized Loss Position Gross unrealized losses on securities without an ACL increased $2.3 billion for the three months ended March 31, 2024 to $28.1 billion primarily due to an increase in interest rates and the impact of weakening foreign currencies on certain non-functional currency denominated fixed maturity securities, partially offset by narrowing credit spreads. As shown in the table 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 March 31, 2024, 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 March 31, 2024, $769 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 March 31, 2024, 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 March 31, 2024. 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.

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 and subsequent performance are considered in determining any ACL recorded. These mortgage loan modifications are summarized as follows:

The carrying value of wholly-owned real estate acquired through foreclosure was $192 million and $190 million at March 31, 2024 and December 31, 2023, respectively. Depreciation expense on real estate investments was $29 million and $28 million for the three months ended March 31, 2024 and 2023, respectively. Real estate investments, net of accumulated depreciation, were $958 million and $952 million at March 31, 2024 and December 31, 2023, respectively. 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. See Note 11 of the Notes to the Consolidated Financial Statements included in the 2023 Annual Report for a summary of leased real estate investments and income earned, by property type. Tax Equity Investments The Company invests in certain tax equity investments, including low income housing tax credit partnerships and renewable energy partnerships. The carrying value of tax equity investments, reported in other invested assets on the interim condensed consolidated balance sheet, was $781 million and $1.0 billion at March 31, 2024 and December 31, 2023, respectively. Beginning January 1, 2024, tax equity investments that meet certain criteria are accounted for using the proportional amortization method, where the initial cost of the investment is amortized in proportion to the tax credits received and recognized as a component of income tax expense (benefit) in the interim condensed consolidated statements of operations. Investments which do not meet the qualification criteria for the proportional amortization method are accounted for using the equity method of accounting. For the three months ended March 31, 2024, income tax credits and other income tax benefits of $37 million and amortized expense of $33 million were recognized net as a component of income tax expense in the Company’s interim condensed consolidated statement of operations. Cash Equivalents Cash equivalents, which includes securities and other investments with an original or remaining maturity of three months or less at the time of purchase, was $11.2 billion and $10.8 billion, principally at estimated fair value, at March 31, 2024 and December 31, 2023, respectively. Concentrations of Credit Risk Investments in any counterparty that were greater than 10% of the Company’s equity, other than the U.S. government and its agencies, at estimated fair value, were in fixed income securities of the following foreign governments and their agencies:

__________________ (1)The related security could be returned to the Company on the next business day, which would require the Company to immediately return the cash collateral. If the Company is required to return significant amounts of cash collateral on short notice and is forced to sell investments to meet the return obligation, it may have difficulty selling such collateral that is invested in a timely manner, be forced to sell investments in a volatile or illiquid market for less than what otherwise would have been realized under normal market conditions, or both. The securities lending and repurchase agreements reinvestment portfolios consist principally of high quality, liquid, publicly traded fixed maturity securities AFS, short-term investments, cash equivalents or cash. If the securities in the reinvestment portfolio become less liquid, liquidity resources within the general account are available to meet any potential cash demands when securities are put back by the counterparty. Invested Assets on Deposit, Held in Trust and Pledged as Collateral Invested assets on deposit, held in trust and pledged as collateral are presented below at estimated fair value for all asset classes, except mortgage loans, which are presented at carrying value, and were as follows at:

(2) The Company has pledged invested assets in connection with various agreements and transactions, including funding agreements, repurchase agreements and a collateral financing arrangement (see Notes 5, 16 and 17 of the Notes to the Consolidated Financial Statements included in the 2023 Annual Report). For information regarding invested assets pledged in connection with derivative transactions, see Note 11. See “— Securities Lending Transactions and Repurchase Agreements” for information regarding securities supporting securities lending transactions and repurchase agreements, and Note 9 for information regarding investments designated to the closed block. In addition, the Company’s investment in Federal Home Loan Bank of New York common stock, included within other invested assets, which is considered restricted until redeemed by the issuer, was $714 million, at redemption value, at both March 31, 2024 and December 31, 2023 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:
|  | March 31, 2024 |  | December 31, 2023

__________________ (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 unrecognized 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. As described in Note 19, 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 either the three months ended March 31, 2024 or 2023.
