Organization, Consolidation and Presentation of Financial Statements [Abstract]
Business, Basis of Presentation and Summary of Significant Accounting Policies	1. Business, Basis of Presentation and Summary of Significant Accounting Policies Business Metropolitan Life Insurance Company and its subsidiaries (collectively, “MLIC” or the “Company”) is a provider of insurance, annuities, employee benefits and asset management and is organized into three segments: Group Benefits, Retirement and Income Solutions (“RIS”), and MetLife Holdings. Metropolitan Life Insurance Company is a wholly-owned subsidiary of MetLife, Inc. (MetLife, Inc., together with its subsidiaries and affiliates, “MetLife”). Basis of Presentation The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to adopt accounting policies and make estimates and assumptions that affect amounts reported on the interim condensed consolidated financial statements. In applying these policies and estimates, management makes subjective and complex judgments that frequently require assumptions about matters that are inherently uncertain. Many of these policies, estimates and related judgments are common in the insurance and financial services industries; others are specific to the Company’s business and operations. Actual results could differ from these estimates. The accompanying interim condensed consolidated financial statements are unaudited and reflect all adjustments (including normal recurring adjustments) necessary to present fairly the financial position, results of operations and cash flows for the interim periods presented in conformity with GAAP. Interim results are not necessarily indicative of full year performance. The December 31, 2023 consolidated balance sheet data was derived from audited consolidated financial statements included in Metropolitan Life Insurance Company’s Annual Report on Form 10-K for the year ended December 31, 2023 (the “2023 Annual Report”), which include all disclosures required by GAAP. Therefore, these interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements of the Company included in the 2023 Annual Report. Consolidation The accompanying interim condensed consolidated financial statements include the accounts of Metropolitan Life Insurance Company and its subsidiaries, as well as partnerships and joint ventures in which the Company has a controlling financial interest, and variable interest entities (“VIEs”) for which the Company is the primary beneficiary. Intercompany accounts and transactions have been eliminated. The Company uses the equity method of accounting, unless the fair value option (“FVO”) is applied, for real estate joint ventures and other limited partnership interests (“investee”) when it has more than a minor ownership interest or more than a minor influence over the investee’s operations. The Company generally recognizes its share of the investee’s earnings in net investment income on 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. Since the Company is a member of a controlled group of affiliated companies, its results may not be indicative of those of a stand-alone entity. Recent Accounting Pronouncements Changes to GAAP are established by the Financial Accounting Standards Board (“FASB”) in the form of Accounting Standards Updates (each, an “ASU”) to the FASB Accounting Standards Codification. The Company considers the applicability and impact of all ASUs. The following tables provide a description of ASUs recently issued by the FASB and the impact of their adoption on the Company’s consolidated financial statements. Adopted Accounting Pronouncements The table below describes the impacts of ASUs adopted by the Company. Standard Description Effective Date and Impact on Financial Statements ASU 2023-02, Investments—Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method The amendments in this update permit reporting entities to elect to account for their tax equity investments, regardless of the tax credit program from which the income tax credits are received, using the proportional amortization method if certain conditions are met. In addition, disclosures describing the nature of the investments and related income tax credits and benefits will be required. January 1, 2024. The Company adopted this update, applying a modified retrospective basis. The Company has elected to use the proportional amortization method to account for its tax equity investments that meet the required criteria. The adoption of this update resulted in a decrease to retained earnings of $219 million, net of income tax, primarily related to the Company’s tax equity investments reported within other invested assets, as of January 1, 2024. Future Adoption of Accounting Pronouncements ASUs not listed below were assessed and either determined to be not applicable or are not expected to have a material impact on the Company’s consolidated financial statements or disclosures. ASUs issued but not yet adopted as of June 30, 2024 that are currently being assessed and may or may not have a material impact on the Company’s consolidated financial statements or disclosures are summarized in the table below. Standard Description Effective Date and Impact on Financial Statements ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures Among other things, the amendments in this update require that public business entities, on an annual basis: (i) disclose specific categories in the rate reconciliation; and (ii) provide additional information for reconciling items that meet a quantitative threshold. In addition, the amendments in this update require that all entities disclose on an annual basis the following information about income taxes paid: (i) the amount of income taxes paid (net of refunds received) disaggregated by federal (national), state, and foreign taxes; and (ii) the amount of income taxes paid (net of refunds received) disaggregated by individual jurisdictions in which income taxes paid (net of refunds received) is equal to or greater than five percent of total income taxes paid (net of refunds received). Effective for annual periods beginning January 1, 2025, to be applied prospectively with an option for retrospective application (with early adoption permitted). The Company is evaluating the impact of the guidance on its consolidated financial statements. ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures The amendments in this update are intended to improve reportable segment disclosure requirements primarily through enhanced disclosures about significant segment expenses. The key amendments include: (i) disclosures on significant segment expenses that are regularly provided to the chief operating decision maker (“CODM”) and included within each reported measure of segment profit or loss on an annual and interim basis; (ii) disclosures on an amount for other segment items by reportable segment and a description of its composition on an annual and interim basis. The other segment items category is the difference between segment revenue less the significant expenses disclosed and each reported measure of segment profit or loss; (iii) providing all annual disclosures on a reportable segment’s profit or loss and assets currently required by FASB ASC Topic 280, Segment Reporting in interim periods; and (iv) specifying the title and position of the CODM. Effective for annual periods beginning January 1, 2024 and interim periods beginning January 1, 2025, to be applied on a retrospective basis unless it is impracticable (with early adoption permitted). The Company is evaluating the impact of the guidance on its consolidated financial statements.

Segment Reporting [Abstract]
Segment Information	2. Segment Information In the fourth quarter of 2023, MLIC reorganized from two segments into the following three segments to reflect changes in management’s responsibilities: Group Benefits, RIS and MetLife Holdings. The Group Benefits and RIS businesses were previously reported as the U.S. segment. These changes were applied retrospectively and did not have an impact on prior period total consolidated net income (loss) or adjusted earnings. In addition, the Company continues to report certain of its results of operations in Corporate & Other. Group Benefits The Group Benefits segment, based in the U.S., offers a broad range of products to corporations and their respective employees, other institutions and their respective members, as well as individuals. These products include term, variable and universal life insurance, dental, group and individual disability and accident & health insurance. RIS The RIS segment, based in the U.S., offers a broad range of life and annuity-based insurance and investment products to corporations and their respective employees, other institutions and their respective members, as well as individuals. These products include stable value and pension risk transfer products, institutional income annuities, structured settlements, benefit funding solutions and capital markets investment products. MetLife Holdings The MetLife Holdings segment consists of operations relating to products and businesses that the Company no longer actively markets in the U.S. These include variable, universal, term and whole life insurance, variable, fixed and index-linked annuities and long-term care insurance. Corporate & Other Corporate & Other contains various start-up, developing and run-off businesses, including the Company’s ancillary non-U.S. operations. Also included in Corporate & Other are: the excess capital, as well as certain charges and activities, not allocated to the segments (including enterprise-wide strategic initiatives), interest expense related to the majority of the Company’s outstanding debt, expenses associated with certain legal proceedings and income tax audit issues, and the elimination of intersegment amounts (which generally relate to intersegment loans bearing interest rates commensurate with related borrowings). Financial Measures and Segment Accounting Policies Adjusted earnings is used by management to evaluate performance and allocate resources. Consistent with GAAP guidance for segment reporting, adjusted earnings is also the Company’s GAAP measure of segment performance and is reported below. Adjusted earnings should not be viewed as a substitute for net income (loss). The Company believes the presentation of adjusted earnings, as the Company measures it for management purposes, enhances the understanding of its performance by highlighting the results of operations and the underlying profitability drivers of the business. Adjusted earnings is defined as adjusted revenues less adjusted expenses, net of income tax. These financial measures focus on the Company’s primary businesses principally by excluding the impact of (i) market volatility which could distort trends, (ii) asymmetrical and non-economic accounting, and (iii) revenues and costs related to divested businesses, non-core products and certain entities required to be consolidated under GAAP. Also, these measures exclude results of discontinued operations under GAAP. Market volatility can have a significant impact on the Company’s financial results. Adjusted earnings excludes net investment gains (losses), net derivative gains (losses), market risk benefits (“MRBs”) remeasurement gains (losses) and goodwill impairments. Further, policyholder benefits and claims exclude (i) changes in the discount rate on certain annuitization guarantees accounted for as additional liabilities, and (ii) market value adjustments. Asymmetrical and non-economic accounting adjustments are made to the line items indicated in calculating adjusted earnings: • Net investment income includes earned income on derivatives and amortization of premium on derivatives that are hedges of investments or that are used to replicate certain investments, but do not qualify for hedge accounting treatment. • Other revenues include settlements of foreign currency earnings hedges and exclude asymmetrical accounting associated with in-force reinsurance. • Policyholder benefits and claims excludes (i) amortization of basis adjustments associated with de-designated fair value hedges of future policy benefits (“FPBs”), (ii) inflation-indexed benefit adjustments associated with contracts backed by inflation-indexed investments, (iii) asymmetrical accounting associated with in-force reinsurance, and (iv) non-economic losses incurred at contract inception for certain single premium annuity business. These losses are amortized into adjusted earnings within policyholder benefits and claims over the estimated lives of the contracts . • Interest credited to policyholder account balances (“PABs”) excludes amounts associated with periodic crediting rate adjustments based on the total return of a contractually referenced pool of assets and other pass-through adjustments and asymmetrical accounting associated with in-force reinsurance. Divested businesses are those that have been or will be sold or exited by MLIC but do not meet the discontinued operations criteria under GAAP. Divested businesses also include the net impact of transactions with exited businesses that have been eliminated in consolidation under GAAP and costs relating to businesses that have been or will be sold or exited by MLIC that do not meet the criteria to be included in results of discontinued operations under GAAP. Other adjustments are made to the line items indicated in calculating adjusted earnings: • Net investment income and interest credited to PABs excludes certain amounts related to contractholder-directed equity securities . • Other revenues include fee revenue on synthetic guaranteed interest contracts (“GICs”) accounted for as freestanding derivatives . • Other revenues exclude and other expenses include fees received in connection with services provided under transition service agreements . • Other expenses exclude (i) implementation of new insurance regulatory requirements and other costs, and (ii) acquisition, integration and other related costs. Other expenses include (i) deductions for net income attributable to noncontrolling interests, and (ii) benefits accrued on synthetic GICs accounted for as freestanding derivatives. Adjusted earnings also excludes the recognition of certain contingent assets and liabilities that could not be recognized at acquisition or adjusted for during the measurement period under GAAP business combination accounting guidance . The tax impact of the adjustments mentioned above are calculated net of the U.S. or foreign statutory tax rate, which could differ from the Company’s effective tax rate. Additionally, the provision for income tax (expense) benefit also includes the impact related to the timing of certain tax credits, as well as certain tax reforms. Set forth in the tables below is certain financial information with respect to the Company’s segments, as well as Corporate & Other, for the three months and six months ended June 30, 2024 and 2023. The segment accounting policies are the same as those used to prepare the Company’s interim condensed consolidated financial statements, except for adjusted earnings adjustments as defined above. In addition, segment accounting policies include the method of capital allocation described below. Economic capital is an internally developed risk capital model, the purpose of which is to measure the risk in the business and to provide a basis upon which capital is deployed. The economic capital model accounts for the unique and specific nature of the risks inherent in MetLife’s and the Company’s businesses. MetLife’s economic capital model, coupled with considerations of local capital requirements, aligns segment allocated equity with emerging standards and consistent risk principles. The model applies statistics-based risk evaluation principles to the material risks to which the Company is exposed. These consistent risk principles include calibrating required economic capital shock factors to a specific confidence level and time horizon while applying an industry standard method for the inclusion of diversification benefits among risk types. MetLife’s management is responsible for the ongoing production and enhancement of the economic capital model and reviews its approach periodically to ensure that it remains consistent with emerging industry practice standards. Segment net investment income is credited or charged based on the level of allocated equity; however, changes in allocated equity do not impact the Company’s consolidated net investment income, net income (loss) or adjusted earnings. Net investment income is based upon the actual results of each segment’s specifically identifiable investment portfolios adjusted for allocated equity. Other costs are allocated to each of the segments based upon: (i) a review of the nature of such costs; (ii) time studies analyzing the amount of employee compensation costs incurred by each segment; and (iii) cost estimates included in the Company’s product pricing.

Market Risk Benefits The Company establishes liabilities for variable annuity contract features which include a minimum benefit guarantee that provides to the contractholder a minimum return based on their initial deposit less withdrawals. In some cases, the benefit base may be increased by additional deposits, bonus amounts, accruals or optional market value resets.

The products grouped within this rollforward were selected based upon common characteristics and valuations using similar inputs, judgments, assumptions and methodologies within a particular segment of the business. MetLife Holdings - Annuities The MetLife Holdings segment’s variable annuity products offer contract features where the Company guarantees to the contractholder a minimum benefit, which includes guaranteed minimum death benefits (“GMDBs”) and living benefit guarantees. The GMDB contract features include return of premium, which provides a return of the purchase payment upon death, annual step-up and roll-up and step-up combinations. The living benefit guarantees contract features primarily include guaranteed minimum income benefits (“GMIBs”), which provide a minimum accumulation of purchase payments that can be annuitized to receive a monthly income stream, and guaranteed minimum withdrawal benefits (“GMWBs”), which provide a series of withdrawals, provided that withdrawals in a contract year do not exceed a contractual limit.

(2) Includes amounts for certain variable annuity guarantees recorded as MRBs on contracts also recorded as PABs which are disclosed in “MetLife Holdings – Annuities” in Note 4. Significant Methodologies and Assumptions The Company issues GMDBs, GMWBs, guaranteed minimum accumulation benefits (“GMABs”) and GMIBs that typically meet the definition of MRBs, which are measured in aggregate, as one compound MRB, at estimated fair value separately from the variable annuity contract, with changes in estimated fair value reported in net income, except for changes in nonperformance risk of the Company which are recorded in other comprehensive income (loss) (“OCI”). The Company calculates the fair value of these MRBs, which is estimated as the present value of projected future benefits minus the present value of projected attributed fees, using actuarial and capital market assumptions including expectations concerning policyholder behavior. The calculation is based on in-force business, projecting future cash flows from the MRB over multiple risk neutral stochastic scenarios using observable risk-free rates. Capital market assumptions, such as risk-free rates and implied volatilities, are based on market prices for publicly traded instruments to the extent that prices for such instruments are observable. Implied volatilities beyond the observable period are extrapolated based on observable implied volatilities and historical volatilities. Actuarial assumptions, including mortality, lapse, withdrawal and utilization, are unobservable and are reviewed at least annually based on actuarial studies of historical experience. See Note 11 for additional information on significant unobservable inputs. The valuation of these MRBs includes a nonperformance risk adjustment and adjustments for a risk margin related to non-capital market inputs. The nonperformance adjustment is determined by taking into consideration publicly available information relating to spreads in the secondary market for MetLife, Inc.’s debt, including related credit default swaps. These observable spreads are then adjusted, as necessary, to reflect the priority of these liabilities and the claims paying ability of the issuing insurance subsidiaries as compared to MetLife, Inc. Risk margins are established to capture the non-capital market risks of the instrument which represent the additional compensation a market participant would require to assume the risks related to the uncertainties of such actuarial assumptions at annuitization, premium persistency, partial withdrawal and surrenders. The establishment of risk margins requires the use of significant management judgment, including assumptions of the amount and cost of capital needed to cover the guarantees. These guarantees may be more costly than expected in volatile or declining equity markets. Market conditions, including changes in interest rates, equity indices, market volatility and foreign currency exchange rates; and variations in actuarial assumptions regarding policyholder behavior, mortality and risk margins related to non-capital market inputs, impact the estimated fair value of the guarantees and affect net income, and changes in nonperformance risk of the Company affect OCI. Other In addition to the disaggregated MRB product rollforward above, the Company offers other products with guaranteed minimum benefit features. These MRBs are measured at estimated fair value, with changes in estimated fair value reported in net income, except for changes in nonperformance risk of the Company which are recorded in OCI. See Note 11 for additional information on significant unobservable inputs used in the fair value measurement of MRBs.

Separate Accounts Disclosure [Abstract]
Separate Account	6. Separate Accounts Separate account assets consist of investment accounts established and maintained by the Company. The investment objectives of these assets are directed by the contractholder. An equivalent amount is reported as separate account liabilities. These accounts are reported separately from the general account assets and liabilities. Separate Account Liabilities The Company’s separate account liabilities on the interim condensed consolidated balance sheets were as follows at: June 30, 2024 December 31, 2023 (In millions) RIS: Stable Value and Risk Solutions $ 32,256 $ 35,562 Annuities 11,246 11,659 MetLife Holdings - Annuities 28,780 29,162 Other 7,303 6,814 Total $ 79,585 $ 83,197 Rollforwards The following information about the separate account liabilities includes disaggregated rollforwards. The products grouped within these rollforwards were selected based upon common characteristics and valuations using similar inputs, judgments, assumptions and methodologies within a particular segment of the business. The separate account liabilities are primarily comprised of the following: RIS stable value and risk solutions contracts, RIS annuities participating and non-participating group contracts, and MetLife Holdings variable annuities. The balances of and changes in separate account liabilities were as follows: RIS RIS MetLife Holdings (In millions) Six Months Ended June 30, 2024 Balance, beginning of period $ 35,562 $ 11,659 $ 29,162 Premiums and deposits 541 25 123 Policy charges (108) (10) (296) Surrenders and withdrawals (2,919) (401) (1,851) Benefit payments (49) — (259) Investment performance 490 (95) 1,964 Net transfers from (to) general account (20) — (58) Other (1) (1,241) 68 (5) Balance, end of period $ 32,256 $ 11,246 $ 28,780 Six Months Ended June 30, 2023 Balance, beginning of period $ 43,249 $ 11,694 $ 28,443 Premiums and deposits 1,069 120 139 Policy charges (121) (11) (305) Surrenders and withdrawals (7,532) (360) (1,359) Benefit payments (44) — (242) Investment performance 1,145 448 2,924 Net transfers from (to) general account (57) 3 (47) Other (667) (102) — Balance, end of period $ 37,042 $ 11,792 $ 29,553 Cash surrender value at June 30, 2024 (2) $ 28,766 N/A $ 28,643 Cash surrender value at June 30, 2023 (2) $ 32,886 N/A $ 29,471 __________________ (1) Other for RIS stable value and risk solutions primarily includes changes related to unsettled trades of mortgage-backed securities.

Evaluation of Fixed Maturity Securities AFS in an Unrealized Loss Position Gross unrealized losses on securities without an ACL increased $2.2 billion for the six months ended June 30, 2024 to $13.9 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. 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 June 30, 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 June 30, 2024, $419 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 June 30, 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 June 30, 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.

The accrued interest income excluded from total amortized cost for commercial, agricultural and residential mortgage loans at June 30, 2024 was $189 million, $158 million and $79 million, respectively. The accrued interest income excluded from total amortized cost for commercial, agricultural and residential mortgage loans at December 31, 2023 was $196 million, $166 million and $79 million, respectively. Purchases of mortgage loans from unaffiliated parties, consisting primarily of residential mortgage loans, were $198 million and $453 million for the three months and six months ended June 30, 2024, respectively, and $100 million and $857 million for the three months and six months ended June 30, 2023, respectively. See “— Related Party Investment Transactions” for information regarding transfers of mortgage loans to and from affiliates. For both the three months and six months ended June 30, 2024, the Company contributed commercial mortgage loans with an amortized cost of $181 million to REJVs which subsequently completed foreclosure on those mortgage loans. See “— Real Estate and REJV” for the carrying value of wholly-owned real estate acquired through foreclosure. Rollforward of ACL for Mortgage Loans by Portfolio Segment The rollforward of ACL for mortgage loans, by portfolio segment, is as follows: Six Months Ended June 30, 2024 2023 Commercial Agricultural Residential Total Commercial Agricultural Residential Total (In millions) Balance, beginning of period $ 210 $ 152 $ 147 $ 509 $ 174 $ 105 $ 169 $ 448 Provision (release) 74 6 (37) 43 37 48 5 90 Charge-offs, net of recoveries (12) (7) — (19) — (13) — (13) Balance, end of period $ 272 $ 151 $ 110 $ 533 $ 211 $ 140 $ 174 $ 525 ACL 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 mortgage 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: Three Months Ended June 30, 2024 2023 Maturity Extension Weighted Average Life Increase Maturity Extension Weighted Average Life Increase Amortized Cost Affected Loans (in Years) % of Book Value Amortized Cost Affected Loans (in Years) % of Book Value (Dollars in millions) Commercial $ 137 Less than one year < 1% $ 149 One year < 1% Six Months Ended June 30, 2024 2023 Maturity Extension Weighted Average Life Increase Maturity Extension Weighted Average Life Increase Amortized Cost Affected Loans (in Years) % of Book Value Amortized Cost Affected Loans (in Years) % of Book Value (Dollars in millions) Commercial $ 167 Less than one year <1% $ 180 Less than one year < 1% During the three months ended June 30, 2024, commercial mortgage loans with an amortized cost of $171 million which were extended over the past 12 months became foreclosed. During the six months ended June 30, 2024, commercial mortgage loans with an amortized cost of $171 million which were extended over the past 12 months became delinquent and foreclosed. For both the three months and six months ended June 30, 2023, all commercial mortgage loans which were modified to borrowers experiencing financial difficulties were current.

Past Due and Nonaccrual Mortgage Loans The Company has a high quality, well performing mortgage loan portfolio, with 99% of all mortgage loans classified as performing at both June 30, 2024 and December 31, 2023. The Company defines delinquency consistent with industry practice, when mortgage loans are past due more than two or more months, as applicable, by portfolio segment. The past due and nonaccrual mortgage loans at amortized cost, prior to ACL, by portfolio segment, were as follows: Past Due Past Due Nonaccrual Portfolio Segment June 30, 2024 December 31, 2023 June 30, 2024 December 31, 2023 June 30, 2024 December 31, 2023 (In millions) Commercial $ 271 $ 19 $ — $ — $ 381 $ 303 Agricultural 188 40 15 — 182 206 Residential 319 343 — — 319 343 Total $ 778 $ 402 $ 15 $ — $ 882 $ 852 Real Estate and REJV The Company’s real estate investment portfolio is diversified by property type, geography and income stream, including income from operating leases, operating income and equity in earnings from equity method REJV. Real estate investments, by income type, as well as income earned, were as follows at and for the periods indicated: June 30, 2024 December 31, 2023 Three Months Six Months 2024 2023 2024 2023 Income Type Carrying Value Income (In millions) Wholly-owned real estate: Leased real estate $ 1,656 $ 1,594 $ 38 $ 41 $ 76 $ 83 Other real estate 518 506 77 83 120 129 REJV 6,895 6,590 (57) (7) (107) (43) Total real estate and REJV $ 9,069 $ 8,690 $ 58 $ 117 $ 89 $ 169 The carrying value of wholly-owned real estate acquired through foreclosure was $263 million and $190 million at June 30, 2024 and December 31, 2023, respectively. Depreciation expense on real estate investments was $23 million and $44 million for the three months and six months ended June 30, 2024, respectively, and $22 million and $42 million for the three months and six months ended June 30, 2023, respectively. Real estate investments net of accumulated depreciation were $683 million and $638 million at June 30, 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, apartment 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 10 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. Other Invested Assets 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 $787 million and $1.0 billion at June 30, 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 and six months ended June 30, 2024, income tax credits and other income tax benefits of $38 million and $75 million, respectively, and amortized expense of $34 million and $67 million , respectively, were recognized net as a component of income tax expense in the Company’s interim condensed consolidated statement of operations.

Derivatives	10. Derivatives Accounting for Derivatives See Note 1 of the Notes to the Consolidated Financial Statements included in the 2023 Annual Report for a description of the Company’s accounting policies for derivatives and Note 11 for information about the fair value hierarchy for derivatives. Derivative Strategies Types of Derivative Instruments and Derivative Strategies The Company is exposed to various risks relating to its ongoing business operations, including interest rate, foreign currency exchange rate, credit and equity market. The Company uses a variety of strategies to manage these risks, including the use of derivatives. Commonly used derivative instruments include, but are not limited to: • Interest rate derivatives: swaps, total return swaps, caps, floors, futures, swaptions, forwards and synthetic GICs; • Foreign currency exchange rate derivatives: swaps and forwards; • Credit derivatives: purchased or written single name or index credit default swaps, and forwards; and • Equity derivatives: index options, variance swaps, exchange-traded futures and total return swaps. For detailed information on these contracts and the related strategies, see Note 11 of the Notes to the Consolidated Financial Statements included in the 2023 Annual Report. Primary Risks Managed by Derivatives The following table presents the primary underlying risk exposure, gross notional amount, and estimated fair value of the Company’s derivatives, excluding embedded derivatives, held at: June 30, 2024 December 31, 2023 Primary Underlying Risk Exposure Gross Notional Amount Estimated Fair Value Gross Estimated Fair Value Assets Liabilities Assets Liabilities (In millions) Derivatives Designated as Hedging Instruments: Fair value hedges: Interest rate swaps Interest rate $ 4,870 $ 1,094 $ 610 $ 4,443 $ 1,257 $ 508 Foreign currency swaps Foreign currency exchange rate 1,317 37 13 1,459 55 1 Subtotal 6,187 1,131 623 5,902 1,312 509 Cash flow hedges: Interest rate swaps Interest rate 3,788 — 323 3,789 1 246 Interest rate forwards Interest rate 369 — 81 970 — 175 Foreign currency swaps Foreign currency exchange rate 31,966 2,181 851 30,342 1,977 846 Subtotal 36,123 2,181 1,255 35,101 1,978 1,267 Total qualifying hedges 42,310 3,312 1,878 41,003 3,290 1,776 Derivatives Not Designated or Not Qualifying as Hedging Instruments: Interest rate swaps Interest rate 15,482 1,428 731 15,516 1,476 638 Interest rate floors Interest rate 8,078 29 — 13,921 39 — Interest rate caps Interest rate 24,970 236 — 28,890 355 — Interest rate futures Interest rate 70 — — 25 — — Interest rate options Interest rate 37,416 216 66 39,226 361 27 Synthetic GICs Interest rate 5,966 — — 6,145 — — Foreign currency swaps Foreign currency exchange rate 4,259 454 9 4,304 446 24 Foreign currency forwards Foreign currency exchange rate 1,097 8 4 1,176 8 10 Credit default swaps — purchased Credit 749 6 3 809 3 7 Credit default swaps — written Credit 11,522 197 5 10,007 186 4 Equity futures Equity market 647 3 1 941 3 — Equity index options Equity market 13,203 222 189 17,703 339 193 Equity total return swaps Equity market 2,020 1 100 1,912 — 218 Total non-designated or nonqualifying derivatives 125,479 2,800 1,108 140,575 3,216 1,121 Total $ 167,789 $ 6,112 $ 2,986 $ 181,578 $ 6,506 $ 2,897 Based on gross notional amounts, a substantial portion of the Company’s derivatives was not designated or did not qualify as part of a hedging relationship at both June 30, 2024 and December 31, 2023. The Company’s use of derivatives includes (i) derivatives that serve as macro hedges of the Company’s exposure to various risks and that generally do not qualify for hedge accounting due to the criteria required under the portfolio hedging rules, (ii) derivatives that economically hedge insurance liabilities that contain mortality or morbidity risk and that generally do not qualify for hedge accounting because the lack of these risks in the derivatives cannot support an expectation of a highly effective hedging relationship, (iii) derivatives that economically hedge MRBs that do not qualify for hedge accounting because the changes in estimated fair value of the MRBs are already recorded in net income, and (iv) written credit default swaps and interest rate swaps that are used to synthetically create investments and that do not qualify for hedge accounting because they do not involve a hedging relationship. For these nonqualified derivatives, changes in market factors can lead to the recognition of fair value changes on the statement of operations without an offsetting gain or loss recognized in earnings for the item being hedged.

Fair Value Hedges The Company designates and accounts for the following as fair value hedges when they have met the requirements of fair value hedging: (i) interest rate swaps to convert fixed rate assets and liabilities to floating rate assets and liabilities, and (ii) foreign currency swaps to hedge the foreign currency fair value exposure of foreign currency denominated assets and liabilities. The following table presents the balance sheet classification, carrying amount and cumulative fair value hedging adjustments for items designated and qualifying as hedged items in fair value hedges: Balance Sheet Line Item Carrying Amount of the Cumulative Amount June 30, 2024 December 31, 2023 June 30, 2024 December 31, 2023 (In millions) Fixed maturity securities AFS $ 118 $ 120 $ 1 $ 1 Mortgage loans $ 208 $ 345 $ (5) $ (10) FPBs $ (2,661) $ (2,863) $ 337 $ 191 PABs $ (2,198) $ (1,844) $ 141 $ 2 __________________ (1) Includes ($101) million and ($113) million of hedging adjustments on discontinued hedging relationships at June 30, 2024 and December 31, 2023, respectively. All components of each derivative’s gain or loss were included in the assessment of hedge effectiveness. Cash Flow Hedges The Company designates and accounts for the following as cash flow hedges when they have met the requirements of cash flow hedging: (i) interest rate swaps to convert floating rate assets and liabilities to fixed rate assets and liabilities, (ii) foreign currency swaps to hedge the foreign currency cash flow exposure of foreign currency denominated assets and liabilities, (iii) interest rate forwards and credit forwards to lock in the price to be paid for forward purchases of investments, and (iv) interest rate swaps and interest rate forwards to hedge the forecasted purchases of fixed-rate investments. In certain instances, the Company discontinued cash flow hedge accounting because the forecasted transactions were no longer probable of occurring. Because certain of the forecasted transactions also were not probable of occurring within two months of the anticipated date, the Company reclassified amounts from AOCI into income. These amounts were $2 million for both the three months and six months ended June 30, 2024, and $19 million and $20 million for the three months and six months ended June 30, 2023, respectively. At both June 30, 2024 and December 31, 2023, the maximum length of time over which the Company was hedging its exposure to variability in future cash flows for forecasted transactions did not exceed five years. At June 30, 2024 and December 31, 2023, the balance in AOCI associated with cash flow hedges was $1.0 billion and $894 million, respectively. All components of each derivative’s gain or loss were included in the assessment of hedge effectiveness. At June 30, 2024, the Company expected to reclassify $289 million of deferred net gains (losses) on derivatives in AOCI to earnings within the next 12 months. Credit Derivatives In connection with synthetically created credit investment transactions, the Company writes credit default swaps for which it receives a premium to insure credit risk. Such credit derivatives are included within the effects of derivatives on the interim condensed consolidated statements of operations and comprehensive income (loss) table. If a credit event occurs, as defined by the contract, the contract may be cash settled or it may be settled gross by the Company paying the counterparty the specified swap notional amount in exchange for the delivery of par quantities of the referenced credit obligation. The Company can terminate these contracts at any time through cash settlement with the counterparty at an amount equal to the then current estimated fair value of the credit default swaps. The following table presents the estimated fair value, maximum amount of future payments and weighted average years to maturity of written credit default swaps at: June 30, 2024 December 31, 2023 Rating Agency Designation of Referenced Estimated Maximum Weighted Estimated Maximum Weighted (Dollars in millions) Aaa/Aa/A Single name credit default swaps (3) $ — $ — — $ — $ 10 0.5 Credit default swaps referencing indices 82 4,125 2.6 80 3,831 2.7 Subtotal 82 4,125 2.6 80 3,841 2.7 Baa Single name credit default swaps (3) 1 55 1.8 1 55 2.3 Credit default swaps referencing indices 105 7,213 4.4 102 5,982 5.6 Subtotal 106 7,268 4.4 103 6,037 5.5 Ba Credit default swaps referencing indices 2 25 2.5 2 25 3.0 Subtotal 2 25 2.5 2 25 3.0 B Credit default swaps referencing indices 5 74 4.5 1 74 5.0 Subtotal 5 74 4.5 1 74 5.0 Caa Credit default swaps referencing indices (3) 30 2.0 (4) 30 2.5 Subtotal (3) 30 2.0 (4) 30 2.5 Total $ 192 $ 11,522 3.7 $ 182 $ 10,007 4.4 __________________ (1) The rating agency designations are based on availability and the midpoint of the applicable ratings among Moody’s Investors Service (“Moody’s”), S&P Global Ratings (“S&P”) and Fitch Ratings.

(2) The weighted average years to maturity of the credit default swaps is calculated based on weighted average gross notional amounts. (3) Single name credit default swaps may be referenced to the credit of corporations, foreign governments, or municipals. Credit Risk on Freestanding Derivatives The Company may be exposed to credit-related losses in the event of nonperformance by its counterparties to derivatives. Generally, the current credit exposure of the Company’s derivatives is limited to the net positive estimated fair value of derivatives at the reporting date after taking into consideration the existence of master netting or similar agreements and any collateral received pursuant to such agreements. The Company manages its credit risk related to derivatives by entering into transactions with creditworthy counterparties in jurisdictions in which it understands that close-out netting should be enforceable and establishing and monitoring exposure limits. The Company’s bilateral contracts between two counterparties (“OTC-bilateral”) derivative transactions are governed by International Swaps and Derivatives Association, Inc. (“ISDA”) Master Agreements which provide for legally enforceable set-off and close-out netting of exposures to specific counterparties in the event of early termination of a transaction, which includes, but is not limited to, events of default and bankruptcy. In the event of an early termination, close-out netting permits the Company (subject to financial regulations such as the Orderly Liquidation Authority under Title II of the Dodd-Frank Wall Street Reform and Consumer Protection Act) to set off receivables from the counterparty against payables to the same counterparty arising out of all included transactions and to apply collateral to the obligations without application of the automatic stay, upon the counterparty’s bankruptcy. All of the Company’s ISDA Master Agreements also include Credit Support Annex provisions which require both the pledging and accepting of collateral in connection with its OTC-bilateral derivatives as required by applicable law. Additionally, the Company is required to pledge initial margin for certain new OTC-bilateral derivative transactions to third party custodians. The Company’s over-the-counter cleared (“OTC-cleared”) derivatives are effected through central clearing counterparties and its exchange-traded derivatives are effected through regulated exchanges. Such positions are marked to market and margined on a daily basis (both initial margin and variation margin), and the Company has minimal exposure to credit-related losses in the event of nonperformance by brokers and central clearinghouses to such derivatives. See Note 11 for a description of the impact of credit risk on the valuation of derivatives. The estimated fair values of the Company’s net derivative assets and net derivative liabilities after the application of master netting agreements and collateral were as follows at: June 30, 2024 December 31, 2023 Derivatives Subject to a Master Netting Arrangement or a Similar Arrangement Assets Liabilities Assets Liabilities (In millions) Gross estimated fair value of derivatives: OTC-bilateral (1) $ 6,083 $ 3,013 $ 6,534 $ 2,892 OTC-cleared (1) 143 41 112 13 Exchange-traded 3 1 3 — Total gross estimated fair value of derivatives presented on the interim condensed consolidated balance sheets (1) 6,229 3,055 6,649 2,905 Gross amounts not offset on the interim condensed consolidated balance sheets: Gross estimated fair value of derivatives: (2) OTC-bilateral (2,411) (2,411) (2,350) (2,350) OTC-cleared (12) (12) (4) (4) Exchange-traded (1) (1) — — Cash collateral: (3), (4) OTC-bilateral (2,645) — (2,872) — OTC-cleared (113) — (105) (1) Securities collateral: (5) OTC-bilateral (1,021) (602) (1,283) (542) OTC-cleared — (29) — (8) Exchange-traded — — — — Net amount after application of master netting agreements and collateral $ 26 $ — $ 35 $ — __________________ (1) At June 30, 2024 and December 31, 2023, derivative assets included income (expense) accruals reported in accrued investment income or in other liabilities of $117 million and $143 million, respectively, and derivative liabilities included (income) expense accruals reported in accrued investment income or in other liabilities of $69 million and $8 million, respectively. (2) Estimated fair value of derivatives is limited to the amount that is subject to set-off and includes income or expense accruals. (3) Cash collateral received by the Company for OTC-bilateral and OTC-cleared derivatives, where the central clearinghouse treats variation margin as collateral, is included in cash and cash equivalents, short-term investments or in fixed maturity securities AFS, and the obligation to return it is included in payables for collateral under securities loaned and other transactions on the balance sheet. (4) The receivable for the return of cash collateral provided by the Company is inclusive of initial margin on exchange- traded and OTC-cleared derivatives and is included in premiums, reinsurance and other receivables on the balance sheet. The amount of cash collateral offset in the table above is limited to the net estimated fair value of derivatives after app lication of netting agreements. At June 30, 2024 and December 31, 2023, the Company received excess cash collateral of $48 million and $154 million, respectively, and provided excess cash collateral of $4 million for both periods, which are not included in the table above due to the foregoing limitation. (5) Securities collateral received by the Company is held in separate custodial accounts and is not recorded on the balance sheet. Subject to certain constraints, the Company is permitted by contract to sell or re-pledge this collateral, but at June 30, 2024, none of the collateral had been sold or re-pledged. Securities collateral pledged by the Company is reported in fixed maturity securities AFS on the balance sheet. Subject to certain constraints, the counterparties are permitted by contract to sell or re-pledge this collateral. The amount of securities collateral offset in the table above is limited to the net estimated fair value of derivatives after application of netting agreements and cash collateral. At June 30, 2024 and December 31, 2023, the Company received excess securities collateral with an estimated fair value of $455 million and $286 million, respectively, for its OTC-bilateral derivatives, which are not included in the table above due to the foregoing limitation. At June 30, 2024 and December 31, 2023, the Company provided excess securities collateral with an estimated fair value of $905 million and $1.1 billion, respectively, for its OTC-bilateral derivatives, $416 million and $495 million, respectively, for its OTC-cleared derivatives, and $31 million and $56 million, respectively, for its exchange-traded derivatives, which are not included in the table above due to th e foregoing limitation. The Company’s collateral arrangements for its OTC-bilateral derivatives generally require the counterparty in a net liability position, after considering the effect of netting agreements, to pledge collateral when the collateral amount owed by that counterparty reaches a minimum transfer amount. All of the Company’s netting agreements for derivatives contain provisions that require both Metropolitan Life Insurance Company and the counterparty to maintain a specific investment grade financial strength or credit rating from each of Moody’s and S&P. If a party’s financial strength or credit rating were to fall below that specific investment grade financial strength or credit rating, that party would be in violation of these provisions, and the other party to the derivatives could terminate the transactions and demand immediate settlement payment based on such party’s reasonable valuation of the derivatives. The following table presents the estimated fair value of the Company’s OTC-bilateral derivatives that were in a net liability position after considering the effect of netting agreements, together with the estimated fair value and balance sheet location of the collateral pledged.

Fair Value	11. Fair Value Considerable judgment is often required in interpreting the market data used to develop estimates of fair value, and the use of different assumptions or valuation methodologies may have a material effect on the estimated fair value amounts. Recurring Fair Value Measurements The assets and liabilities measured at estimated fair value on a recurring basis and their corresponding placement in the fair value hierarchy, including those items for which the Company has elected the FVO, are presented below at: June 30, 2024 Fair Value Hierarchy Level 1 Level 2 Level 3 Total Estimated Fair Value (In millions) Assets Fixed maturity securities AFS: U.S. corporate $ — $ 39,926 $ 8,921 $ 48,847 Foreign corporate — 15,875 8,554 24,429 U.S. government and agency 10,834 11,705 — 22,539 RMBS — 18,818 1,746 20,564 ABS & CLO — 10,043 1,867 11,910 Municipals — 5,477 — 5,477 CMBS — 4,914 500 5,414 Foreign government — 2,965 11 2,976 Total fixed maturity securities AFS 10,834 109,723 21,599 142,156 Short-term investments 1,479 186 3 1,668 Other investments 46 91 1,434 1,571 Derivative assets: (1) Interest rate — 3,003 — 3,003 Foreign currency exchange rate — 2,680 — 2,680 Credit — 203 — 203 Equity market 3 217 6 226 Total derivative assets 3 6,103 6 6,112 Embedded derivatives within asset host contracts (4) — — 126 126 MRBs — — 230 230 Separate account assets (2) 13,630 64,986 969 79,585 Total assets (3) $ 25,992 $ 181,089 $ 24,367 $ 231,448 Liabilities Derivative liabilities: (1) Interest rate $ — $ 1,730 $ 81 $ 1,811 Foreign currency exchange rate — 877 — 877 Credit — 8 — 8 Equity market 1 289 — 290 Total derivative liabilities 1 2,904 81 2,986 Embedded derivatives within liability host contracts (4) — — (279) (279) MRBs — — 2,391 2,391 Separate account liabilities (2) — 3 — 3 Total liabilities $ 1 $ 2,907 $ 2,193 $ 5,101 December 31, 2023 Fair Value Hierarchy Level 1 Level 2 Level 3 Total Estimated Fair Value (In millions) Assets Fixed maturity securities AFS: U.S. corporate $ — $ 41,718 $ 8,775 $ 50,493 Foreign corporate — 16,875 8,340 25,215 U.S. government and agency 8,963 12,097 — 21,060 RMBS 3 17,616 1,329 18,948 ABS & CLO — 10,109 1,532 11,641 Municipals — 6,319 — 6,319 CMBS — 5,499 335 5,834 Foreign government — 3,281 14 3,295 Total fixed maturity securities AFS 8,966 113,514 20,325 142,805 Short-term investments 2,745 288 15 3,048 Other investments 76 77 1,317 1,470 Derivative assets: (1) Interest rate — 3,489 — 3,489 Foreign currency exchange rate — 2,486 — 2,486 Credit — 181 8 189 Equity market 3 332 7 342 Total derivative assets 3 6,488 15 6,506 Embedded derivatives within asset host contracts (4) — — 15 15 MRBs — — 177 177 Separate account assets (2) 13,945 68,284 968 83,197 Total assets (3) $ 25,735 $ 188,651 $ 22,832 $ 237,218 Liabilities Derivative liabilities: (1) Interest rate $ — $ 1,419 $ 175 $ 1,594 Foreign currency exchange rate — 881 — 881 Credit — 11 — 11 Equity market — 411 — 411 Total derivative liabilities — 2,722 175 2,897 Embedded derivatives within liability host contracts (4) — — (37) (37) MRBs — — 2,878 2,878 Separate account liabilities (2) 4 4 — 8 Total liabilities $ 4 $ 2,726 $ 3,016 $ 5,746 __________________ (1) Derivative assets are presented within other invested assets on the interim condensed consolidated balance sheets and derivative liabilities are presented within other liabilities on the interim condensed consolidated balance sheets.

(2) Investment performance related to separate account assets is fully offset by corresponding amounts credited to contractholders whose liability is reflected within separate account liabilities. Separate account liabilities are set equal to the estimated fair value of separate account assets. Separate account liabilities presented in the tables above represent derivative liabilities. (3) Total assets included in the fair value hierarchy exclude OLPI that are measured at estimated fair value using the net asset value (“NAV”) per share (or its equivalent) practical expedient. The estimated fair value of such investments was $48 million at both June 30, 2024 and December 31, 2023. (4) Embedded derivatives within asset host contracts are presented within other invested assets on the interim condensed consolidated balance sheets. Embedded derivatives within liability host contracts are presented within PABs and other liabilities on the interim condensed consolidated balance sheets. The following describes the valuation methodologies used to measure assets and liabilities at fair value. Investments Securities, Short-term Investments and Other Investments When available, the estimated fair value of these financial instruments is based on quoted prices in active markets that are readily and regularly obtainable. Generally, these are the most liquid of the Company’s securities holdings, and valuation of these securities does not involve management’s judgment. When quoted prices in active markets are not available, the determination of estimated fair value of securities is based on market standard valuation methodologies, giving priority to observable inputs. The significant inputs to the market standard valuation methodologies for certain types of securities with reasonable levels of price transparency are inputs that are observable in the market or can be derived principally from, or corroborated by, observable market data. When observable inputs are not available, the market standard valuation methodologies rely on inputs that are significant to the estimated fair value that are not observable in the market or cannot be derived principally from, or corroborated by, observable market data. These unobservable inputs can be based, in large part, on management’s judgment or estimation and cannot be supported by reference to market activity. Unobservable inputs are based on management’s assumptions about the inputs market participants would use in pricing such investments. The estimated fair value of short-term investments and other investments is determined on a basis consistent with the methodologies described herein. The valuation approaches and key inputs for each category of assets or liabilities that are classified within Level 2 and Level 3 of the fair value hierarchy are presented below. The primary valuation approaches are the market approach, which considers recent prices from market transactions involving identical or similar assets or liabilities, and the income approach, which converts expected future amounts (e.g., cash flows) to a single current, discounted amount. The valuation of most instruments listed below is determined using independent pricing sources, matrix pricing, discounted cash flow methodologies or other similar techniques that use either observable market inputs or unobservable inputs. Instrument Level 2 Observable Inputs Level 3 Unobservable Inputs Fixed maturity securities AFS U.S. corporate and Foreign corporate securities Valuation Approaches: Principally the market and income approaches. Valuation Approaches: Principally the market approach. Key Inputs: Key Inputs: • quoted prices in markets that are not active • illiquidity premium • benchmark yields; spreads off benchmark yields; new issuances; issuer ratings • delta spread adjustments to reflect specific credit-related issues • trades of identical or comparable securities; duration • credit spreads • privately-placed securities are valued using the additional key inputs: • quoted prices in markets that are not active for identical or similar securities that are less liquid and based on lower levels of trading activity than securities classified in Level 2 • market yield curve; call provisions • observable prices and spreads for similar public or private securities that incorporate the credit quality and industry sector of the issuer • independent non-binding broker quotations • delta spread adjustments to reflect specific credit-related issues U.S. government and agency securities, Municipals and Foreign government securities Valuation Approaches: Principally the market approach.

The valuation approaches and observable inputs used in their valuation are also similar to those described above. Other investments contain equity securities valued using quoted prices in markets that are not considered active. • Certain short-term investments and certain other investments are of a similar nature and class to the fixed maturity securities AFS described above, while certain other investments are similar to equity securities. The valuation approaches and unobservable inputs used in their valuation are also similar to those described above. Other investments contain equity securities that use key unobservable inputs such as credit ratings, issuance structures and those described above for fixed maturities AFS. Other investments also include certain REJV and use the valuation approach and key inputs as described for OLPI below. Separate account assets and Separate account liabilities (1) Mutual funds and hedge funds without readily determinable fair values as prices are not published publicly Key Input: • N/A • quoted prices or reported NAV provided by the fund managers OLPI • N/A Valued giving consideration to the underlying holdings Key Inputs: • liquidity; bid/ask spreads; performance record of the fund manager • other relevant variables that may impact the exit value of the particular partnership interest __________________ (1) Estimated fair value equals carrying value, based on the value of the underlying assets, including: mutual fund interests, fixed maturity securities, equity securities, derivatives, hedge funds, OLPI, short-term investments and cash and cash equivalents. The estimated fair value of fixed maturity securities, equity securities, derivatives, short-term investments and cash and cash equivalents is determined on a basis consistent with the assets described under “— Securities, Short-term Investments and Other Investments” and “— Derivatives — Freestanding Derivatives.” Derivatives The estimated fair value of derivatives is determined through the use of quoted market prices for exchange-traded derivatives, or through the use of pricing models for OTC-bilateral and OTC-cleared derivatives. The determination of estimated fair value, when quoted market values are not available, is based on market standard valuation methodologies and inputs that management believes are consistent with what other market participants would use when pricing such instruments. Derivative valuations can be affected by changes in interest rates, foreign currency exchange rates, financial indices, credit spreads, default risk, nonperformance risk, volatility, liquidity and changes in estimates and assumptions used in the pricing models. The significant inputs to the pricing models for most OTC-bilateral and OTC-cleared derivatives are inputs that are observable in the market or can be derived principally from, or corroborated by, observable market data. With respect to certain OTC-bilateral and OTC-cleared derivatives, management may rely on inputs that are significant to the estimated fair value that are not observable in the market or cannot be derived principally from, or corroborated by, observable market data. These unobservable inputs may involve significant management judgment or estimation. Unobservable inputs are based on management’s assumptions about the inputs market participants would use in pricing such derivatives. Most inputs for OTC-bilateral and OTC-cleared derivatives are mid-market inputs but, in certain cases, liquidity adjustments are made when they are deemed more representative of exit value. Market liquidity, as well as the use of different methodologies, assumptions and inputs, may have a material effect on the estimated fair values of the Company’s derivatives and could materially affect net income. The credit risk of both the counterparty and the Company is considered in determining the estimated fair value for all OTC-bilateral and OTC-cleared derivatives, and any potential credit adjustment is based on the net exposure by counterparty after taking into account the effects of netting agreements and collateral arrangements. The Company values its OTC-bilateral and OTC-cleared derivatives using standard swap curves which may include a spread to the risk-free rate, depending upon specific collateral arrangements. This credit spread is appropriate for those parties that execute trades at pricing levels consistent with similar collateral arrangements. As the Company and its significant derivative counterparties generally execute trades at such pricing levels and hold sufficient collateral, additional credit risk adjustments are not currently required in the valuation process. The Company’s ability to consistently execute at such pricing levels is, in part, due to the netting agreements and collateral arrangements that are in place with all of its significant derivative counterparties. An evaluation of the requirement to make additional credit risk adjustments is performed by the Company each reporting period. Freestanding Derivatives Level 2 Valuation Approaches and Key Inputs: This level includes all types of derivatives utilized by the Company with the exception of exchange-traded derivatives included within Level 1 and those derivatives with unobservable inputs as described in Level 3. Level 3 Valuation Approaches and Key Inputs: These valuation methodologies generally use the same inputs as described in the corresponding sections for Level 2 measurements of derivatives. However, these derivatives result in Level 3 classification because one or more of the significant inputs are not observable in the market or cannot be derived principally from, or corroborated by, observable market data. Freestanding derivatives are principally valued using the income approach. Valuations of non-option-based derivatives utilize present value techniques, whereas valuations of option-based derivatives utilize option pricing models. Key inputs are as follows: Instrument Interest Rate Foreign Currency Credit Equity Market Inputs common to Level 2 and Level 3 by instrument type • swap yield curves • swap yield curves • swap yield curves • swap yield curves • basis curves • basis curves • credit curves • spot equity index levels • interest rate volatility (1) • currency spot rates • recovery rates • dividend yield curves • cross currency basis curves • equity volatility (1) Level 3 • swap yield curves (2) • swap yield curves (2) • swap yield curves (2) • dividend yield curves (2) • basis curves (2) • basis curves (2) • credit curves (2) • equity volatility (1), (2) • repurchase rates • cross currency basis curves (2) • credit spreads • correlation between model inputs (1) • interest rate volatility (1), (2) • currency correlation • repurchase rates • independent non-binding broker quotations __________________ (1) Option-based only. (2) Extrapolation beyond the observable limits of the curve(s). Embedded Derivatives Embedded derivatives principally include equity-indexed annuity contracts and investment risk within funds withheld related to certain reinsurance agreements. Embedded derivatives are recorded at estimated fair value with changes in estimated fair value reported in net income. The estimated fair value of the embedded derivatives within funds withheld related to certain ceded reinsurance and experience refund related to certain assumed reinsurance is determined based on the change in estimated fair value of the underlying assets held by the Company in a reference portfolio backing the reinsurance liability. The estimated fair value of the underlying assets is determined as described in “— Investments — Securities, Short-term Investments and Other Investments.” The estimated fair value of these embedded derivatives is included, along with their underlying host contracts, in other liabilities and other invested assets on the interim condensed consolidated balance sheets with changes in estimated fair value recorded in net derivative gains (losses). Changes in the credit spreads on the underlying assets, interest rates and market volatility may result in significant fluctuations in the estimated fair value of these embedded derivatives that could materially affect net income. The estimated fair value of the embedded equity indexed derivatives, based on the present value of future equity returns to the policyholder using actuarial and present value assumptions including expectations concerning policyholder behavior, is calculated by the Company’s actuarial department. The calculation is based on in-force business and uses standard capital market techniques, such as Black-Scholes, to calculate the value of the portion of the embedded derivative for which the terms are set. The portion of the embedded derivative covering the period beyond where terms are set is calculated as the present value of amounts expected to be spent to provide equity indexed returns in those periods. The valuation of these embedded derivatives also includes the establishment of a risk margin, as well as changes in nonperformance risk. MRBs See Note 5 for information on the Company’s valuation approaches and key inputs for MRBs. Transfers between Levels Overall, transfers between levels occur when there are changes in the observability of inputs and market activity. Transfers into or out of Level 3: Assets and liabilities are transferred into Level 3 when a significant input cannot be corroborated with market observable data. This occurs when market activity decreases significantly and underlying inputs cannot be observed, current prices are not available, and/or when there are significant variances in quoted prices, thereby affecting transparency. Assets and liabilities are transferred out of Level 3 when circumstances change such that a significant input can be corroborated with market observable data. This may be due to a significant increase in market activity, a specific event, or one or more significant input(s) becoming observable. Assets and Liabilities Measured at Fair Value Using Significant Unobservable Inputs (Level 3) The following table presents certain quantitative information about the significant unobservable inputs used in the fair value measurement, and the sensitivity of the estimated fair value to changes in those inputs, for the more significant asset and liability classes measured at fair value on a recurring basis using significant unobservable inputs (Level 3) at: June 30, 2024 December 31, 2023 Impact of Valuation Techniques Significant Range Weighted Range Weighted Fixed maturity securities AFS (3) U.S. corporate and foreign corporate • Matrix pricing • Offered quotes (4) 53 - 125 93 4 - 131 95 Increase • Market pricing • Quoted prices (4) 27 - 111 94 — - 110 93 Increase RMBS • Market pricing • Quoted prices (4) — - 116 96 — - 112 93 Increase (5) ABS & CLO • Market pricing • Quoted prices (4) 84 - 103 96 78 - 101 94 Increase (5) Derivatives Interest rate • Present value techniques • Swap yield (6) 428 - 452 437 367 - 399 385 Increase (7) Credit • Consensus pricing • Offered quotes (8) MRBs Direct and assumed guaranteed minimum benefits • Option pricing techniques • Mortality rates: Ages 0 - 40 0.01% - 0.13% 0.05% 0.01% - 0.13% 0.05% (9) Ages 41 - 60 0.05% - 0.67% 0.22% 0.05% - 0.67% 0.22% (9) Ages 61 - 115 0.35% - 100% 1.23% 0.35% - 100% 1.23% (9) • Lapse rates: Durations 1 - 10 0.80% - 20.10% 8.72% 0.80% - 20.10% 8.72% Decrease (10) Durations 11 - 20 3.10% - 10.10% 4.34% 3.10% - 10.10% 4.34% Decrease (10) Durations 21 - 116 0.10% - 10.10% 4.59% 0.10% - 10.10% 4.59% Decrease (10) • Utilization rates 0.20% - 22% 0.44% 0.20% - 22% 0.44% Increase (11) • Withdrawal rates 0.25% - 7.75% 4.47% 0.25% - 7.75% 4.47% (12) • Long-term equity volatilities 16.37% - 21.85% 18.55% 16.37% - 21.85% 18.55% Increase (13) • Nonperformance risk spread 0.33% - 0.66% 0.73% 0.38% - 0.70% 0.73% Decrease (14) __________________ (1) The weighted average for fixed maturity securities AFS and derivatives is determined based on the estimated fair value of the securities and derivatives. The weighted average for MRBs is determined based on a combination of account values and experience data. (2) The impact of a decrease in input would have resulted in the opposite impact on estimated fair value. For MRBs, changes to direct and assumed guaranteed minimum benefits are based on liability positions. (3) Significant increases (decreases) in expected default rates in isolation would have resulted in substantially lower (higher) valuations. (4) Range and weighted average are presented in accordance with the market convention for fixed maturity securities AFS of dollars per hundred dollars of par. (5) Changes in the assumptions used for the probability of default would have been accompanied by a directionally similar change in the assumption used for the loss severity and a directionally opposite change in the assumptions used for prepayment rates. (6) Ranges represent the rates across different yield curves and are presented in basis points. The swap yield curves are utilized among different types of derivatives to project cash flows, as well as to discount future cash flows to present value. Since this valuation methodology uses a range of inputs across a yield curve to value the derivative, presenting a range is more representative of the unobservable input used in the valuation. (7) Changes in estimated fair value are based on long U.S. dollar net asset positions and will be inversely impacted for short U.S. dollar net asset positions. (8) At June 30, 2024 and December 31, 2023, independent non-binding broker quotations were used in the determination of 0% and less than 1%, respectively, of the total net derivative estimated fair value. (9) Mortality rates vary by age and by demographic characteristics such as gender. Mortality rate assumptions are based on company experience. A mortality improvement assumption is also applied. For any given contract, mortality rates vary throughout the period over which cash flows are projected for purposes of valuing the MRBs. For contracts that contain only a GMDB, any increase (decrease) in mortality rates result in an increase (decrease) in the estimated fair value of MRBs. Generally, for contracts that contain both a GMDB and a living benefit (e.g., GMIB, GMWB, GMAB), any increase (decrease) in mortality rates result in a decrease (increase) in the estimated fair value of MRBs. (10) Base lapse rates are adjusted at the contract level based on a comparison of the actuarially calculated guaranteed values and the current policyholder account value, as well as other factors, such as the applicability of any surrender charges. A dynamic lapse function reduces the base lapse rate when the guaranteed amount is greater than the account value as in the money contracts are less likely to lapse. Lapse rates are also generally assumed to be lower in periods when a surrender charge applies. For any given contract, lapse rates vary throughout the period over which cash flows are projected for purposes of valuing the MRBs. (11) The utilization rate assumption estimates the percentage of contractholders with GMIBs or a lifetime withdrawal benefit who will elect to utilize the benefit upon becoming eligible. The rates may vary by the type of guarantee, the amount by which the guaranteed amount is greater than the account value, the contract’s withdrawal history and by the age of the policyholder. For any given contract, utilization rates vary throughout the period over which cash flows are projected for purposes of valuing the MRBs. (12) The withdrawal rate represents the percentage of account balance that any given policyholder will elect to withdraw from the contract each year. The withdrawal rate assumption varies by age and duration of the contract, and also by other factors such as benefit type. For any given contract, withdrawal rates vary throughout the period over which cash flows are projected for purposes of valuing the MRBs. For GMWBs, any increase (decrease) in withdrawal rates results in an increase (decrease) in the estimated fair value of the guarantees. For GMABs and GMIBs, any increase (decrease) in withdrawal rates results in a decrease (increase) in the estimated fair value. (13) Long-term equity volatilities represent equity volatility beyond the period for which observable equity volatilities are available. For any given contract, long-term equity volatility rates vary throughout the period over which cash flows are projected for purposes of valuing the MRBs. (14) Nonperformance risk spread varies by duration and by currency. For any given contract, multiple nonperformance risk spreads will apply, depending on the duration of the cash flow being discounted for purposes of valuing the MRBs. All other classes of securities classified within Level 3, including those within Other investments, Separate account assets, and Embedded derivatives within funds withheld related to certain ceded reinsurance, use the same valuation techniques and significant unobservable inputs as previously described for Level 3 securities. Generally, all other classes of assets and liabilities classified within Level 3 that are not included above use the same valuation techniques and significant unobservable inputs as previously described for Level 3. The sensitivity of the estimated fair value to changes in the significant unobservable inputs for these other assets and liabilities is similar in nature to that described in the preceding table. The valuation techniques and significant unobservable inputs used in the fair value measurement for the more significant assets measured at estimated fair value on a nonrecurring basis and determined using significant unobservable inputs (Level 3) are summarized in “— Nonrecurring Fair Value Measurements.” The following tables summarize the change of assets (liabilities) measured at estimated fair value on a recurring basis using significant unobservable inputs (Level 3), excluding MRBs (see Note 5): Fair Value Measurements Using Significant Unobservable Inputs (Level 3) Fixed Maturity Securities AFS Corporate (6) Structured Municipals Foreign Short-term (In millions) Three Months Ended June 30, 2024 Balance, beginning of period $ 17,154 $ 3,543 $ — $ 15 $ 11 Total realized/unrealized gains (losses) included in net income (loss) (1), (2) (29) 10 — — — Total realized/unrealized gains (losses) included in AOCI (137) 13 — (4) — Purchases (3) 1,148 934 — — 1 Sales (3) (620) (104) — — (9) Issuances (3) — — — — — Settlements (3) — — — — — Transfers into Level 3 (4) 64 51 — — — Transfers out of Level 3 (4) (105) (334) — — — Balance, end of period $ 17,475 $ 4,113 $ — $ 11 $ 3 Three Months Ended June 30, 2023 Balance, beginning of period $ 15,717 $ 3,501 $ — $ 15 $ 57 Total realized/unrealized gains (losses) included in net income (loss) (1), (2) (11) 7 — (1) — Total realized/unrealized gains (losses) included in AOCI (101) (20) — 3 (1) Purchases (3) 808 67 4 — 5 Sales (3) (393) (86) — — (44) Issuances (3) — — — — — Settlements (3) — — — — — Transfers into Level 3 (4) 125 34 — — — Transfers out of Level 3 (4) (129) (94) — — — Balance, end of period $ 16,016 $ 3,409 $ 4 $ 17 $ 17 Changes in unrealized gains (losses) included in net income (loss) for the instruments still held at June 30, 2024 (5) $ (11) $ 9 $ — $ — $ — Changes in unrealized gains (losses) included in net income (loss) for the instruments still held at June 30, 2023 (5) $ (10) $ 8 $ — $ (1) $ — Changes in unrealized gains (losses) included in AOCI for the instruments still held at June 30, 2024 (5) $ (147) $ 12 $ — $ (4) $ — Changes in unrealized gains (losses) included in AOCI for the instruments still held at June 30, 2023 (5) $ (110) $ (21) $ — $ 3 $ (1) Fair Value Measurements Using Significant Unobservable Inputs (Level 3) Other Investments Net Net Embedded Separate (In millions) Three Months Ended June 30, 2024 Balance, beginning of period $ 1,403 $ (121) $ 285 $ 980 Total realized/unrealized gains (losses) included in net income (loss) (1), (2) 28 (1) 121 (5) Total realized/unrealized gains (losses) included in AOCI — (14) — — Purchases (3) 12 — — 44 Sales (3) (9) — — (50) Issuances (3) — — — — Settlements (3) — 67 (1) — Transfers into Level 3 (4) — — — — Transfers out of Level 3 (4) — (6) — — Balance, end of period $ 1,434 $ (75) $ 405 $ 969 Three Months Ended June 30, 2023 Balance, beginning of period $ 1,052 $ (271) $ 168 $ 1,000 Total realized/unrealized gains (losses) included in net income (loss) (1), (2) 63 (12) 212 (10) Total realized/unrealized gains (losses) included in AOCI — (39) — — Purchases (3) — — — 72 Sales (3) — — — (20) Issuances (3) — — — — Settlements (3) — 44 (2) — Transfers into Level 3 (4) — — — 12 Transfers out of Level 3 (4) — — — — Balance, end of period $ 1,115 $ (278) $ 378 $ 1,054 Changes in unrealized gains (losses) included in net income (loss) for the instruments still held at June 30, 2024 (5) $ 28 $ — $ 121 $ — Changes in unrealized gains (losses) included in net income (loss) for the instruments still held at June 30, 2023 (5) $ 64 $ 1 $ 212 $ — Changes in unrealized gains (losses) included in AOCI for the instruments still held at June 30, 2024 (5) $ — $ (9) $ — $ — Changes in unrealized gains (losses) included in AOCI for the instruments still held at June 30, 2023 (5) $ — $ (48) $ — $ — Fair Value Measurements Using Significant Unobservable Inputs (Level 3) Fixed Maturity Securities AFS Corporate (6) Structured Municipals Foreign Short-term (In millions) Six Months Ended June 30, 2024 Balance, beginning of period $ 17,115 $ 3,196 $ — $ 14 $ 15 Total realized/unrealized gains (losses) included in net income (loss) (1), (2) (42) 14 — 2 — Total realized/unrealized gains (losses) included in AOCI (317) 53 — (5) — Purchases (3) 1,783 1,104 — — 3 Sales (3) (1,038) (257) — — (15) Issuances (3) — — — — — Settlements (3) — — — — — Transfers into Level 3 (4) 97 101 — — — Transfers out of Level 3 (4) (123) (98) — — — Balance, end of period $ 17,475 $ 4,113 $ — $ 11 $ 3 Six Months Ended June 30, 2023 Balance, beginning of period $ 14,733 $ 3,373 $ — $ 15 $ 47 Total realized/unrealized gains (losses) included in net income (loss) (1), (2) (18) 1 — (1) — Total realized/unrealized gains (losses) included in AOCI 285 — — 2 — Purchases (3) 2,015 153 4 2 17 Sales (3) (848) (175) — (1) (47) Issuances (3) — — — — —

Income Tax	14. Income Tax For both the three months and six months ended June 30, 2024, the effective tax rate on income (loss) before provision for income tax was 19%. The Company’s effective tax rate for the three months ended June 30, 2024 differed from the U.S. statutory rate of 21% primarily due to tax benefits from (i) non-taxable investment income and (ii) low income housing and other tax credits, partially offset by the impact of tax equity investments now accounted for under the proportional amortization method. The Company’s effective tax rate for the six months ended June 30, 2024 differed from the U.S. statutory rate of 21% primarily due to tax benefits from (i) non-taxable investment income, (ii) low income housing and other tax credits, partially offset by the impact of tax equity investments now accounted for under the proportional amortization method, and (iii) the corporate tax deduction for stock compensation.

Contingencies, Commitments and Guarantees	15. Contingencies, Commitments and Guarantees Contingencies Litigation The Company is a defendant in a large number of litigation matters. Putative or certified class action litigation and other litigation and claims and assessments against the Company, in addition to those discussed below and those otherwise provided for in the Company’s interim condensed consolidated financial statements, have arisen in the course of the Company’s business, including, but not limited to, in connection with its activities as an insurer, mortgage lending bank, employer, investor, investment advisor, broker-dealer, and taxpayer. The Company also receives and responds to subpoenas or other inquiries seeking a broad range of information from state regulators, including state insurance commissioners; state attorneys general or other state governmental authorities; federal regulators, including the U.S. Securities and Exchange Commission; federal governmental authorities, including congressional committees; and the Financial Industry Regulatory Authority, as well as from local and national regulators and government authorities in jurisdictions outside the United States where the Company conducts business. The issues involved in information requests and regulatory matters vary widely, but can include inquiries or investigations concerning the Company’s compliance with applicable insurance and other laws and regulations. The Company cooperates in these inquiries. It is not possible to predict the ultimate outcome of all pending investigations and legal proceedings. The Company establishes liabilities for litigation and regulatory loss contingencies when it is probable that a loss has been incurred and the amount of the loss can be reasonably estimated. In certain circumstances where liabilities have been established there may be coverage under one or more corporate insurance policies, pursuant to which there may be an insurance recovery. Insurance recoveries are recognized as gains when any contingencies relating to the insurance claim have been resolved, which is the earlier of when the gains are realized or realizable. It is possible that some of the matters could require the Company to pay damages or make other expenditures or establish accruals in amounts that could not be reasonably estimated at June 30, 2024. While the potential future charges could be material in the particular quarterly or annual periods in which they are recorded, based on information currently known to management, management does not believe any such charges are likely to have a material effect on the Company’s financial position. Given the large and/or indeterminate amounts sought in certain of these matters and the inherent unpredictability of litigation, it is possible that an adverse outcome in certain matters could, from time to time, have a material effect on the Company’s consolidated net income or cash flows in particular quarterly or annual periods. Matters as to Which an Estimate Can Be Made For some matters, the Company is able to estimate a reasonably possible range of loss. For matters where a loss is believed to be reasonably possible, but not probable, the Company has not made an accrual. As of June 30, 2024, the Company estimates the aggregate range of reasonably possible losses in excess of amounts accrued for these matters to be $0 to $125 million. Matters as to Which an Estimate Cannot Be Made For other matters, the Company is not currently able to estimate the reasonably possible loss or range of loss. The Company is often unable to estimate the possible loss or range of loss until developments in such matters have provided sufficient information to support an assessment of the range of possible loss, such as quantification of a damage demand from plaintiffs, discovery from other parties and investigation of factual allegations, rulings by the court on motions or appeals, analysis by experts, and the progress of settlement negotiations. On a quarterly and annual basis, the Company reviews relevant information with respect to litigation contingencies and updates its accruals, disclosures and estimates of reasonably possible losses or ranges of loss based on such reviews. Asbestos-Related Claims Metropolitan Life Insurance Company is and has been a defendant in a large number of asbestos-related suits filed primarily in state courts. These suits principally allege that the plaintiff or plaintiffs suffered personal injury resulting from exposure to asbestos and seek both actual and punitive damages. Metropolitan Life Insurance Company has never engaged in the business of manufacturing or selling asbestos-containing products, nor has Metropolitan Life Insurance Company issued liability or workers’ compensation insurance to companies in the business of manufacturing or selling asbestos-containing products. The lawsuits principally have focused on allegations with respect to certain research, publication and other activities of one or more of Metropolitan Life Insurance Company’s employees during the period from the 1920s through approximately the 1950s and allege that Metropolitan Life Insurance Company learned or should have learned of certain health risks posed by asbestos and, among other things, improperly publicized or failed to disclose those health risks. Metropolitan Life Insurance Company believes that it should not have legal liability in these cases. The outcome of most asbestos litigation matters, however, is uncertain and can be impacted by numerous variables, including differences in legal rulings in various jurisdictions, the nature of the alleged injury and factors unrelated to the ultimate legal merit of the claims asserted against Metropolitan Life Insurance Company. Metropolitan Life Insurance Company’s defenses include that: (i) Metropolitan Life Insurance Company owed no duty to the plaintiffs; (ii) plaintiffs did not rely on any actions of Metropolitan Life Insurance Company; (iii) Metropolitan Life Insurance Company’s conduct was not the cause of the plaintiffs’ injuries; and (iv) plaintiffs’ exposure occurred after the dangers of asbestos were known. During the course of the litigation, certain trial courts have granted motions dismissing claims against Metropolitan Life Insurance Company, while other trial courts have denied Metropolitan Life Insurance Company’s motions. There can be no assurance that Metropolitan Life Insurance Company will receive favorable decisions on motions in the future. While most cases brought to date have settled, Metropolitan Life Insurance Company intends to continue to defend aggressively against claims based on asbestos exposure, including defending claims at trials. As reported in the 2023 Annual Report, Metropolitan Life Insurance Company received approximately 2,565 asbestos-related claims in 2023. For the six months ended June 30, 2024 and 2023, Metropolitan Life Insurance Company received approximately 1,556 and 1,306 new asbestos-related claims, respectively. See Note 19 of the Notes to the Consolidated Financial Statements included in the 2023 Annual Report for historical information concerning asbestos claims and Metropolitan Life Insurance Company’s update in its recorded liability at December 31, 2023. The number of asbestos cases that may be brought, the aggregate amount of any liability that Metropolitan Life Insurance Company may incur, and the total amount paid in settlements in any given year are uncertain and may vary significantly from year to year. The ability of Metropolitan Life Insurance Company to estimate its ultimate asbestos exposure is subject to considerable uncertainty, and the conditions impacting its liability can be dynamic and subject to change. The availability of reliable data is limited and it is difficult to predict the numerous variables that can affect liability estimates, including the number of future claims, the cost to resolve claims, the disease mix and severity of disease in pending and future claims, the willingness of courts to allow plaintiffs to pursue claims against Metropolitan Life Insurance Company when exposure to asbestos took place after the dangers of asbestos exposure were well known, and the impact of any possible future adverse verdicts and their amounts. The ability to make estimates regarding ultimate asbestos exposure declines significantly as the estimates relate to years further in the future. In the Company’s judgment, there is a future point after which losses cease to be probable and reasonably estimable. It is reasonably possible that the Company’s total exposure to asbestos claims may be materially greater than the asbestos liability currently accrued and that future charges to income may be necessary, but management does not believe any such charges are likely to have a material effect on the Company’s financial position. The Company believes adequate provision has been made in its interim condensed consolidated financial statements for all probable and reasonably estimable losses for asbestos-related claims. Metropolitan Life Insurance Company’s recorded asbestos liability covers pending claims, claims not yet asserted, and legal defense costs and is based on estimates and includes significant assumptions underlying its analysis. Metropolitan Life Insurance Company reevaluates on a quarterly and annual basis its exposure from asbestos litigation, including studying its claims experience, reviewing external literature regarding asbestos claims experience in the United States, assessing relevant trends impacting asbestos liability and considering numerous variables that can affect its asbestos liability exposure on an overall or per claim basis. Based upon its regular reevaluation of its exposure from asbestos litigation, Metropolitan Life Insurance Company has updated its liability analysis for asbestos-related claims through June 30, 2024. Total Asset Recovery Services, LLC. v. MetLife, Inc., et al. (Supreme Court of the State of New York, County of New York, filed December 27, 2017) Total Asset Recovery Services (the “Relator”) brought an action under the qui tam provision of the New York False Claims Act (the “Act”) on behalf of itself and the State of New York. The Relator originally filed this action under seal in 2010, and the complaint was unsealed on December 19, 2017. The Relator alleges that MetLife, Inc., Metropolitan Life Insurance Company and several other insurance companies violated the Act by filing false unclaimed property reports with the State of New York from 1986 to 2017, to avoid having to escheat the proceeds of more than 25,000 life insurance policies, including policies for which the defendants escheated funds as part of their demutualizations in the late 1990s. The Relator seeks treble damages and other relief. The Appellate Division of the New York State Supreme Court, First Department, reversed the court’s order granting MetLife, Inc. and Metropolitan Life Insurance Company’s motion to dismiss and remanded the case to the trial court where the Relator has filed an amended complaint. The Company intends to defend the action vigorously. Matters Related to Group Annuity Benefits In 2018, the Company announced that it identified a material weakness in its internal control over financial reporting related to the practices and procedures for estimating reserves for certain group annuity benefits. Several regulators have made inquiries into the issue, and it is possible that other jurisdictions may pursue similar investigations or inquiries. The Company could be exposed to lawsuits, and additional legal actions relating to this issue. These may result in payments, including damages, fines, penalties, interest and other amounts assessed or awarded by courts or regulatory authorities under applicable escheat, tax, securities, Employee Retirement Income Security Act of 1974, or other laws or regulations. The Company could incur significant costs in connection with these actions. Commitments Mortgage Loan Commitments The Company commits to lend funds under mortgage loan commitments. The amounts of these mortgage loan commitments were $2.5 billion and $3.3 billion at June 30, 2024 and December 31, 2023, respectively. Commitments to Fund Partnership Investments, Bank Credit Facilities and Private Corporate Bond Investments The Company commits to fund partnership investments and to lend funds under bank credit facilities and private corporate bond investments. The amounts of these unfunded commitments were $4.3 billion and $4.4 billion at June 30, 2024 and December 31, 2023, respectively. Guarantees In the normal course of its business, the Company has provided certain indemnities and guarantees to third parties such that it may be required to make payments now or in the future. In the context of acquisition, disposition, investment and other transactions, the Company has provided indemnities and guarantees, including those related to tax, environmental and other specific liabilities and other indemnities and guarantees that are triggered by, among other things, breaches of representations, warranties or covenants provided by the Company. In addition, in the normal course of business, the Company provides indemnifications to counterparties in contracts with triggers similar to the foregoing, as well as for certain other liabilities, such as third-party lawsuits. These obligations are often subject to time limitations that vary in duration, including contractual limitations and those that arise by operation of law, such as applicable statutes of limitation. In some cases, the maximum potential obligation under the indemnities and guarantees is subject to a contractual limitation ranging from less than $1 million to $550 million, with a cumulative maximum of $649 million, while in other cases such limitations are not specified or applicable. Since certain of these obligations are not subject to limitations, the Company does not believe that it is possible to determine the maximum potential amount that could become due under these guarantees in the future. Management believes that it is unlikely the Company will have to make any material payments under these indemnities or guarantees. In addition, the Company indemnifies its directors and officers as provided in its charters and by-laws. Also, the Company indemnifies its agents for liabilities incurred as a result of their representation of the Company’s interests. Since these indemnities are generally not subject to limitation with respect to duration or amount, the Company does not believe that it is possible to determine the maximum potential amount that could become due under these indemnities in the future.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Use of Estimates	The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to adopt accounting policies and make estimates and assumptions that affect amounts reported on the interim condensed consolidated financial statements. In applying these policies and estimates, management makes subjective and complex judgments that frequently require assumptions about matters that are inherently uncertain. Many of these policies, estimates and related judgments are common in the insurance and financial services industries; others are specific to the Company’s business and operations. Actual results could differ from these estimates.
Consolidation of Subsidiaries	The accompanying interim condensed consolidated financial statements are unaudited and reflect all adjustments (including normal recurring adjustments) necessary to present fairly the financial position, results of operations and cash flows for the interim periods presented in conformity with GAAP. Interim results are not necessarily indicative of full year performance. The December 31, 2023 consolidated balance sheet data was derived from audited consolidated financial statements included in Metropolitan Life Insurance Company’s Annual Report on Form 10-K for the year ended December 31, 2023 (the “2023 Annual Report”), which include all disclosures required by GAAP. Therefore, these interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements of the Company included in the 2023 Annual Report. Consolidation The accompanying interim condensed consolidated financial statements include the accounts of Metropolitan Life Insurance Company and its subsidiaries, as well as partnerships and joint ventures in which the Company has a controlling financial interest, and variable interest entities (“VIEs”) for which the Company is the primary beneficiary. Intercompany accounts and transactions have been eliminated. The Company uses the equity method of accounting, unless the fair value option (“FVO”) is applied, for real estate joint ventures and other limited partnership interests (“investee”) when it has more than a minor ownership interest or more than a minor influence over the investee’s operations. The Company generally recognizes its share of the investee’s earnings in net investment income on 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. Since the Company is a member of a controlled group of affiliated companies, its results may not be indicative of those of a stand-alone entity. Closed block assets, liabilities, revenues and expenses are combined on a line-by-line basis with the assets, liabilities, revenues and expenses outside the closed block based on the nature of the particular item.
New Accounting Pronouncements	Recent Accounting Pronouncements Changes to GAAP are established by the Financial Accounting Standards Board (“FASB”) in the form of Accounting Standards Updates (each, an “ASU”) to the FASB Accounting Standards Codification. The Company considers the applicability and impact of all ASUs. The following tables provide a description of ASUs recently issued by the FASB and the impact of their adoption on the Company’s consolidated financial statements. Adopted Accounting Pronouncements The table below describes the impacts of ASUs adopted by the Company. Standard Description Effective Date and Impact on Financial Statements ASU 2023-02, Investments—Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method The amendments in this update permit reporting entities to elect to account for their tax equity investments, regardless of the tax credit program from which the income tax credits are received, using the proportional amortization method if certain conditions are met. In addition, disclosures describing the nature of the investments and related income tax credits and benefits will be required. January 1, 2024. The Company adopted this update, applying a modified retrospective basis. The Company has elected to use the proportional amortization method to account for its tax equity investments that meet the required criteria. The adoption of this update resulted in a decrease to retained earnings of $219 million, net of income tax, primarily related to the Company’s tax equity investments reported within other invested assets, as of January 1, 2024. Future Adoption of Accounting Pronouncements ASUs not listed below were assessed and either determined to be not applicable or are not expected to have a material impact on the Company’s consolidated financial statements or disclosures. ASUs issued but not yet adopted as of June 30, 2024 that are currently being assessed and may or may not have a material impact on the Company’s consolidated financial statements or disclosures are summarized in the table below. Standard Description Effective Date and Impact on Financial Statements ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures Among other things, the amendments in this update require that public business entities, on an annual basis: (i) disclose specific categories in the rate reconciliation; and (ii) provide additional information for reconciling items that meet a quantitative threshold. In addition, the amendments in this update require that all entities disclose on an annual basis the following information about income taxes paid: (i) the amount of income taxes paid (net of refunds received) disaggregated by federal (national), state, and foreign taxes; and (ii) the amount of income taxes paid (net of refunds received) disaggregated by individual jurisdictions in which income taxes paid (net of refunds received) is equal to or greater than five percent of total income taxes paid (net of refunds received). Effective for annual periods beginning January 1, 2025, to be applied prospectively with an option for retrospective application (with early adoption permitted). The Company is evaluating the impact of the guidance on its consolidated financial statements. ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures The amendments in this update are intended to improve reportable segment disclosure requirements primarily through enhanced disclosures about significant segment expenses. The key amendments include: (i) disclosures on significant segment expenses that are regularly provided to the chief operating decision maker (“CODM”) and included within each reported measure of segment profit or loss on an annual and interim basis; (ii) disclosures on an amount for other segment items by reportable segment and a description of its composition on an annual and interim basis. The other segment items category is the difference between segment revenue less the significant expenses disclosed and each reported measure of segment profit or loss; (iii) providing all annual disclosures on a reportable segment’s profit or loss and assets currently required by FASB ASC Topic 280, Segment Reporting in interim periods; and (iv) specifying the title and position of the CODM. Effective for annual periods beginning January 1, 2024 and interim periods beginning January 1, 2025, to be applied on a retrospective basis unless it is impracticable (with early adoption permitted). The Company is evaluating the impact of the guidance on its consolidated financial statements.
Closed Block	On April 7, 2000 (the “Demutualization Date”), Metropolitan Life Insurance Company converted from a mutual life insurance company to a stock life insurance company and became a wholly-owned subsidiary of MetLife, Inc. The conversion was pursuant to an order by the New York Superintendent of Insurance approving Metropolitan Life Insurance Company’s plan of reorganization, as amended (the “Plan of Reorganization”). On the Demutualization Date, Metropolitan Life Insurance Company established a closed block for the benefit of holders of certain individual life insurance policies of Metropolitan Life Insurance Company. See Note 9 to the Notes to the Consolidated Financial Statements included in the 2023 Annual Report for further information on the closed block. Experience within the closed block, in particular mortality and investment yields, as well as realized and unrealized gains and losses, directly impact the policyholder dividend obligation. Amortization of the closed block DAC, which resides outside of the closed block, is based upon policy count within the closed block.
Investments	Maturities of Fixed Maturity Securities AFS Actual maturities may differ from contractual maturities due to the exercise of call or prepayment options. Fixed maturity securities AFS not due at a single maturity date have been presented in the year of final contractual maturity. Structured Products are shown separately, as they are not due at a single maturity. Evaluation and Measurement Methodologies See Note 10 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. ACL 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.

Derivatives	The Company is exposed to various risks relating to its ongoing business operations, including interest rate, foreign currency exchange rate, credit and equity market. The Company uses a variety of strategies to manage these risks, including the use of derivatives. The Company designates and accounts for the following as fair value hedges when they have met the requirements of fair value hedging: (i) interest rate swaps to convert fixed rate assets and liabilities to floating rate assets and liabilities, and (ii) foreign currency swaps to hedge the foreign currency fair value exposure of foreign currency denominated assets and liabilities. The Company designates and accounts for the following as cash flow hedges when they have met the requirements of cash flow hedging: (i) interest rate swaps to convert floating rate assets and liabilities to fixed rate assets and liabilities, (ii) foreign currency swaps to hedge the foreign currency cash flow exposure of foreign currency denominated assets and liabilities, (iii) interest rate forwards and credit forwards to lock in the price to be paid for forward purchases of investments, and (iv) interest rate swaps and interest rate forwards to hedge the forecasted purchases of fixed-rate investments. The Company may be exposed to credit-related losses in the event of nonperformance by its counterparties to derivatives. Generally, the current credit exposure of the Company’s derivatives is limited to the net positive estimated fair value of derivatives at the reporting date after taking into consideration the existence of master netting or similar agreements and any collateral received pursuant to such agreements. The Company manages its credit risk related to derivatives by entering into transactions with creditworthy counterparties in jurisdictions in which it understands that close-out netting should be enforceable and establishing and monitoring exposure limits. The Company’s bilateral contracts between two counterparties (“OTC-bilateral”) derivative transactions are governed by International Swaps and Derivatives Association, Inc. (“ISDA”) Master Agreements which provide for legally enforceable set-off and close-out netting of exposures to specific counterparties in the event of early termination of a transaction, which includes, but is not limited to, events of default and bankruptcy. In the event of an early termination, close-out netting permits the Company (subject to financial regulations such as the Orderly Liquidation Authority under Title II of the Dodd-Frank Wall Street Reform and Consumer Protection Act) to set off receivables from the counterparty against payables to the same counterparty arising out of all included transactions and to apply collateral to the obligations without application of the automatic stay, upon the counterparty’s bankruptcy. All of the Company’s ISDA Master Agreements also include Credit Support Annex provisions which require both the pledging and accepting of collateral in connection with its OTC-bilateral derivatives as required by applicable law. Additionally, the Company is required to pledge initial margin for certain new OTC-bilateral derivative transactions to third party custodians. The Company’s over-the-counter cleared (“OTC-cleared”) derivatives are effected through central clearing counterparties and its exchange-traded derivatives are effected through regulated exchanges. Such positions are marked to market and margined on a daily basis (both initial margin and variation margin), and the Company has minimal exposure to credit-related losses in the event of nonperformance by brokers and central clearinghouses to such derivatives. See Note 11 for a description of the impact of credit risk on the valuation of derivatives.

(2) Investment performance related to separate account assets is fully offset by corresponding amounts credited to contractholders whose liability is reflected within separate account liabilities. Separate account liabilities are set equal to the estimated fair value of separate account assets. Separate account liabilities presented in the tables above represent derivative liabilities. (3) Total assets included in the fair value hierarchy exclude OLPI that are measured at estimated fair value using the net asset value (“NAV”) per share (or its equivalent) practical expedient. The estimated fair value of such investments was $48 million at both June 30, 2024 and December 31, 2023. (4) Embedded derivatives within asset host contracts are presented within other invested assets on the interim condensed consolidated balance sheets. Embedded derivatives within liability host contracts are presented within PABs and other liabilities on the interim condensed consolidated balance sheets.
Fair Value Inputs, Quantitative Information	The following table presents certain quantitative information about the significant unobservable inputs used in the fair value measurement, and the sensitivity of the estimated fair value to changes in those inputs, for the more significant asset and liability classes measured at fair value on a recurring basis using significant unobservable inputs (Level 3) at: June 30, 2024 December 31, 2023 Impact of Valuation Techniques Significant Range Weighted Range Weighted Fixed maturity securities AFS (3) U.S. corporate and foreign corporate • Matrix pricing • Offered quotes (4) 53 - 125 93 4 - 131 95 Increase • Market pricing • Quoted prices (4) 27 - 111 94 — - 110 93 Increase RMBS • Market pricing • Quoted prices (4) — - 116 96 — - 112 93 Increase (5) ABS & CLO • Market pricing • Quoted prices (4) 84 - 103 96 78 - 101 94 Increase (5) Derivatives Interest rate • Present value techniques • Swap yield (6) 428 - 452 437 367 - 399 385 Increase (7) Credit • Consensus pricing • Offered quotes (8) MRBs Direct and assumed guaranteed minimum benefits • Option pricing techniques • Mortality rates: Ages 0 - 40 0.01% - 0.13% 0.05% 0.01% - 0.13% 0.05% (9) Ages 41 - 60 0.05% - 0.67% 0.22% 0.05% - 0.67% 0.22% (9) Ages 61 - 115 0.35% - 100% 1.23% 0.35% - 100% 1.23% (9) • Lapse rates: Durations 1 - 10 0.80% - 20.10% 8.72% 0.80% - 20.10% 8.72% Decrease (10) Durations 11 - 20 3.10% - 10.10% 4.34% 3.10% - 10.10% 4.34% Decrease (10) Durations 21 - 116 0.10% - 10.10% 4.59% 0.10% - 10.10% 4.59% Decrease (10) • Utilization rates 0.20% - 22% 0.44% 0.20% - 22% 0.44% Increase (11) • Withdrawal rates 0.25% - 7.75% 4.47% 0.25% - 7.75% 4.47% (12) • Long-term equity volatilities 16.37% - 21.85% 18.55% 16.37% - 21.85% 18.55% Increase (13) • Nonperformance risk spread 0.33% - 0.66% 0.73% 0.38% - 0.70% 0.73% Decrease (14) __________________ (1) The weighted average for fixed maturity securities AFS and derivatives is determined based on the estimated fair value of the securities and derivatives. The weighted average for MRBs is determined based on a combination of account values and experience data. (2) The impact of a decrease in input would have resulted in the opposite impact on estimated fair value. For MRBs, changes to direct and assumed guaranteed minimum benefits are based on liability positions. (3) Significant increases (decreases) in expected default rates in isolation would have resulted in substantially lower (higher) valuations. (4) Range and weighted average are presented in accordance with the market convention for fixed maturity securities AFS of dollars per hundred dollars of par. (5) Changes in the assumptions used for the probability of default would have been accompanied by a directionally similar change in the assumption used for the loss severity and a directionally opposite change in the assumptions used for prepayment rates. (6) Ranges represent the rates across different yield curves and are presented in basis points. The swap yield curves are utilized among different types of derivatives to project cash flows, as well as to discount future cash flows to present value. Since this valuation methodology uses a range of inputs across a yield curve to value the derivative, presenting a range is more representative of the unobservable input used in the valuation. (7) Changes in estimated fair value are based on long U.S. dollar net asset positions and will be inversely impacted for short U.S. dollar net asset positions. (8) At June 30, 2024 and December 31, 2023, independent non-binding broker quotations were used in the determination of 0% and less than 1%, respectively, of the total net derivative estimated fair value. (9) Mortality rates vary by age and by demographic characteristics such as gender. Mortality rate assumptions are based on company experience. A mortality improvement assumption is also applied. For any given contract, mortality rates vary throughout the period over which cash flows are projected for purposes of valuing the MRBs. For contracts that contain only a GMDB, any increase (decrease) in mortality rates result in an increase (decrease) in the estimated fair value of MRBs. Generally, for contracts that contain both a GMDB and a living benefit (e.g., GMIB, GMWB, GMAB), any increase (decrease) in mortality rates result in a decrease (increase) in the estimated fair value of MRBs. (10) Base lapse rates are adjusted at the contract level based on a comparison of the actuarially calculated guaranteed values and the current policyholder account value, as well as other factors, such as the applicability of any surrender charges. A dynamic lapse function reduces the base lapse rate when the guaranteed amount is greater than the account value as in the money contracts are less likely to lapse. Lapse rates are also generally assumed to be lower in periods when a surrender charge applies. For any given contract, lapse rates vary throughout the period over which cash flows are projected for purposes of valuing the MRBs. (11) The utilization rate assumption estimates the percentage of contractholders with GMIBs or a lifetime withdrawal benefit who will elect to utilize the benefit upon becoming eligible. The rates may vary by the type of guarantee, the amount by which the guaranteed amount is greater than the account value, the contract’s withdrawal history and by the age of the policyholder. For any given contract, utilization rates vary throughout the period over which cash flows are projected for purposes of valuing the MRBs. (12) The withdrawal rate represents the percentage of account balance that any given policyholder will elect to withdraw from the contract each year. The withdrawal rate assumption varies by age and duration of the contract, and also by other factors such as benefit type. For any given contract, withdrawal rates vary throughout the period over which cash flows are projected for purposes of valuing the MRBs. For GMWBs, any increase (decrease) in withdrawal rates results in an increase (decrease) in the estimated fair value of the guarantees. For GMABs and GMIBs, any increase (decrease) in withdrawal rates results in a decrease (increase) in the estimated fair value. (13) Long-term equity volatilities represent equity volatility beyond the period for which observable equity volatilities are available. For any given contract, long-term equity volatility rates vary throughout the period over which cash flows are projected for purposes of valuing the MRBs. (14) Nonperformance risk spread varies by duration and by currency. For any given contract, multiple nonperformance risk spreads will apply, depending on the duration of the cash flow being discounted for purposes of valuing the MRBs.
