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 two segments: U.S. 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. Except for balances affected by the adoption of Accounting Standards Update (“ASU”) 2018-12 noted below, the December 31, 2022 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, 2022 (the “2022 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 2022 Annual Report. Adoption of ASU 2018-12 - Targeted Improvements to the Accounting for Long-Duration Contracts Effective January 1, 2023, the Company adopted ASU 2018-12, Financial Services—Insurance (Topic 944): Targeted Improvements to the Accounting for Long-Duration Contracts , as amended by ASU 2019-09, Financial Services—Insurance (Topic 944): Effective Date ; ASU 2020-11, Financial Services—Insurance (Topic 944): Effective Date and Early Application ; and ASU 2022-05, Financial Services—Insurance (Topic 944): Transition for Sold Contracts (“LDTI”), with a transition date of January 1, 2021 (the “Transition Date”). Adoption of LDTI impacted the Company’s accounting and presentation related to long-duration insurance contracts and certain related balances for the years ended December 31, 2022 and 2021. Amounts within these interim condensed consolidated financial statements which were previously presented, have been revised to conform with the current year accounting and presentation under LDTI. Disclosures as of the Transition Date are reflected in summary within “— Recent Accounting Pronouncements — Adoption of ASU 2018-12 - Targeted Improvements to the Accounting for Long-Duration Contracts,” and in further detail (at the disaggregated level) within Notes 3, 4, 5 and 7. 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 or the fair value option (“FVO”) 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. Revisions Cash flows from short term investments in the prior years’ Interim Condensed Consolidated Statement of Cash Flows, which were previously presented net, have been revised to gross presentation to conform with the current year presentation. The revision in presentation was not material to the previously presented financial statements. Pending Reinsurance Transaction In May 2023, the Company entered into a definitive agreement with a subsidiary of Global Atlantic Financial Group, a retirement and life insurance company, to reinsure an in-force block of universal life, variable universal life, universal life with secondary guarantees, and fixed annuities, which are reported in the MetLife Holdings segment. At the closing of the transaction, the Company will enter into a reinsurance agreement on a coinsurance basis for the general account products, and on a modified coinsurance basis for the separate account products, representing total liabilities of approximately $12.8 billion at September 30, 2023. Under the terms of such agreement, assets primarily consisting of fixed maturity securities available-for-sale and mortgage loans supporting the general account liabilities will be transferred to the reinsurer at closing, reduced by an approximately $1.8 billion pre-tax ceding commission. The Company will retain separate account assets of approximately $4.7 billion at September 30, 2023 under the modified coinsurance arrangement. The transaction is expected to close in the fourth quarter of 2023 and is subject to satisfaction of certain remaining closing conditions. As of October 31, 2023, the Company had received all required regulatory approvals. See Note 9 for additional information on assets to be transferred to the reinsurer at closing, including associated impairments recorded to net investment gains (losses). Summary of Significant Accounting Policies The following table presents the Company’s significant accounting policies which have changed as a result of the adoption of LDTI with cross-references to the notes which provide additional information on such policies. Accounting Policy Note Future Policy Benefit Liabilities 3 Policyholder Account Balances 4 Market Risk Benefits 5 Deferred Policy Acquisition Costs, Value of Business Acquired and Unearned Revenue 7 Derivatives 10 Future Policy Benefit Liabilities Traditional Non-participating and Limited-payment Long-duration products The Company establishes future policy benefit liabilities (“FPBs”) for amounts payable under traditional non-participating and limited-payment long-duration insurance and reinsurance policies which include, but are not limited to, pension risk transfers, structured settlements, institutional income annuities and long-term care products. Generally, amounts are payable over an extended period of time and the related liabilities are calculated as the present value of future expected benefits and claim settlement expenses to be paid, reduced by the present value of future expected net premiums. FPBs are measured as cohorts (e.g., groups of long-duration contracts), with the exception of pension risk transfers and longevity reinsurance solutions contracts, each of which are generally considered their own cohort. Contracts from different subsidiaries or branches, issue years, benefit currencies and product types are not grouped together in the same cohort. Such liabilities are established based on methods and underlying assumptions in accordance with GAAP and applicable actuarial standards. A net premium ratio (“NPR”) approach is utilized, where net premiums (i.e., the portion of gross premiums required to fund expected insurance benefits and claim settlement expenses) under the contract are accrued each period as an FPB. The NPR used to accrue the FPB in each period is determined by using the historical and present value of expected future benefits and claim settlement expenses for the cohort divided by the historical and present value of expected future gross premiums for the cohort. Cash flow assumptions are incorporated into the calculation of a cohort's NPR and FPB reserve. These assumptions are used to project the amount and timing of expected benefits and claim settlement expenses to be paid and the expected amount of premiums to be collected for a cohort. The principal inputs and assumptions used in the establishment of FPBs are actual premiums, actual benefits, in-force policies, and best estimate cash flow assumptions to project future premium and benefit amounts. The Company’s primary best estimate cash flow assumptions include expectations related to mortality, morbidity, termination, claim settlement expense, policy lapse, renewal, retirement, disability incidence, disability terminations, inflation and other contingent events as appropriate to the respective product type and geographical area. Upon transition to LDTI, generally, the NPR and FPB reserve are updated retrospectively on a quarterly basis for actual experience and at least once a year for any changes in future cash flow assumptions, except for claim settlement expenses, for which the Company has elected to lock in assumptions at the Transition Date or inception (for contracts sold after the Transition Date), as allowed by LDTI. The resulting remeasurement (gain) loss is recorded through net income and reflects the impact on the change in the NPR based on experience at end of the quarter applied to the cumulative premiums received from the inception of the cohort (or from the Transition Date for contracts issued prior to the Transition Date) to the beginning of the quarter. The total contractual profit pattern is recognized over the expected life of the cohort by retrospectively updating the NPR. If net premiums exceed gross premiums (i.e., expected benefits exceed expected gross premiums), the FPB is increased, and a corresponding adjustment is recognized immediately in net income. The change in FPB reflected in the statement of operations is calculated using a locked-in discount rate. For products issued prior to the Transition Date, a cohort level locked-in discount rate was developed that reflected the interest accretion rates that were locked in at inception of the underlying contracts (unless there was a historical premium deficiency event that resulted in updating the interest accretion rate prior to the Transition Date), or the acquisition date for contracts acquired through an assumed in-force reinsurance transaction or a business combination. For contracts issued subsequent to the Transition Date, the upper-medium grade discount rate used for interest accretion is locked in for the cohort and represents the original upper-medium grade discount rate at the issue date of the underlying contracts. The FPB for all cohorts is remeasured to a current upper-medium grade discount rate at each reporting date through other comprehensive income (loss) (“OCI”). The Company generally interprets the upper-medium grade discount rate to be a rate comparable to that of a U.S. corporate single A rate that reflects the duration characteristics of the liability. The upper-medium grade discount rate for the products that are included in the disaggregated rollforwards in Note 3 which are issued in the U.S. is determined by using observable market data, including published single A base curves. The last liquid point on the upper-medium grade discount curve grades to an ultimate forward rate, which is derived using assumptions of economic growth, inflation, and a long-term upper-medium grade spread. For limited-payment long-duration contracts, the collection of premiums does not represent the completion of the earnings process, therefore, any gross premiums received in excess of net premiums is deferred and amortized as a deferred profit liability (“DPL”). The DPL is presented within FPBs and is amortized in proportion to either the present value of expected benefit payments or insurance in-force of each cohort to ensure that profits are recognized over the life of the underlying policies in that cohort, regardless of when premiums are received. This amortization of the DPL is recorded through net income within policyholder benefits and claims. Consistent with the Company’s measurement of traditional long-duration products, management also recognizes a FPB reserve for limited-payment contracts that is representative of the difference between the present value of expected future benefit payments and the present value of expected future net premiums, subject to retrospective remeasurement through net income and OCI, as described above. The DPL is also subject to retrospective remeasurement through net income, however, it is not remeasured for changes in discount rates. Traditional Participating Products The Company establishes FPBs for traditional participating contracts in the U.S., which include whole and term life participating contracts in both the open and closed block using a net premium approach, similar to traditional non-participating contracts. However, for participating contracts, the discount rate and actuarial assumptions are locked in at inception, include a provision for adverse deviation, and all changes in the associated FPBs are reported within policyholder benefits and claims. See Note 8 for additional information on the closed block. For traditional participating contracts, the Company reviews its estimates of actuarial liabilities for future benefits and compares them with current best estimate assumptions. The Company revises estimates, to increase FPBs, if the Company determines that the liabilities previously established for future benefit payments less future expected net premiums in the aggregate for this line of business prove inadequate. Additional Insurance Liabilities Liabilities for universal, variable universal, and variable life policies with secondary guarantees (“ULSG”) and paid-up guarantees are determined by estimating the expected value of death benefits payable when the account balance is projected to be zero and recognizing those benefits ratably over the life of the contract based on total expected assessments. The additional insurance liabilities are updated retrospectively on a quarterly basis for actual experience and at least once a year for any changes in future cash flow assumptions. The assumptions used in estimating the secondary and paid-up guarantee liabilities are investment income, mortality, lapse, and premium payment pattern and persistency. The assumptions of investment performance and volatility for variable products are consistent with historical experience of appropriate underlying equity indices, such as the S&P Global Ratings (“S&P”) 500 Index. The benefits used in calculating the liabilities are based on the average benefits payable over a range of scenarios. The resulting remeasurement (gain) loss recorded through net income reflects the impact on the change in the ratio of benefits payable to total assessments over the life of the contract based on experience at end of the quarter applied to the cumulative assessments received as of the beginning of the quarter. Premium Deficiency Reserves on Short-Duration Contracts Premium deficiency reserves may be established for short-duration contracts to provide for expected future losses and certain expenses that exceed unearned premiums. These reserves are based on actuarial estimates of the amount of loss inherent in that period, including losses incurred for which claims have not been reported. The provisions for unreported claims are calculated using studies that measure the historical length of time between the incurred date of a claim and its eventual reporting to the Company. Anticipated investment income is considered in the calculation of premium deficiency losses for short-duration contracts. Policyholder Account Balances Policyholder account balances (“PABs”) represent the amount held by the Company on behalf of the policyholder at each reporting date. This amount includes deposits received from the policyholder, interest credited to the policyholder’s account balance, net of charges assessed against the account balance and any policyholder withdrawals. This balance also includes liabilities for structured settlement and institutional income annuities, and certain other contracts, that do not contain significant insurance risk, as well as the estimated fair value of embedded derivatives associated with indexed annuity products. Market Risk Benefits As defined by LDTI, market risk benefits (“MRBs”) are contracts or contract features that guarantee benefits, such as guaranteed minimum benefits, in addition to an account balance, which expose insurance companies to other than nominal capital market risk (equity price, interest rate, and/or foreign currency exchange risk) and subsequently protect the contractholder from the same risk. These contracts and contract features were generally recorded as embedded derivatives or additional insurance liabilities prior to the Transition Date. Certain contracts may have multiple contract features or guarantees. In these cases, each feature is separately evaluated to determine whether it meets the definition of an MRB at contract inception. If a contract includes multiple benefits that meet the definition of an MRB, those benefits are aggregated and measured as a single compound MRB. All identified MRBs are required to be measured at estimated fair value, whether the contract or contract feature represents a direct, assumed or ceded capital market risk. All MRBs in an asset position are aggregated and presented as an asset, and all MRBs in a liability position are aggregated and presented as a liability. Changes in the estimated fair value of MRBs are recognized in net income, except for the portion of the fair value change attributable to the change in nonperformance risk of the Company which is recorded as a separate component of OCI. The Company generally uses an attributed fee approach to value MRBs, where the attributed fee is determined at contract inception by estimating the fair value of expected future benefits and the expected future fees. The attributed fee percentage is the portion of the expected future fees due from contractholders deemed necessary at contract inception to fund all future expected benefits. This typically results in a zero fair value for the MRB at inception. The estimated fair value of the expected future benefits is estimated using a stochastically-generated set of risk-neutral scenarios. Once calculated, the attributed fee percentage is fixed and does not change over the life of the contract. All fees due from contractholders in excess of the attributed fees are reported in universal life and investment-type product policy fees. Other Policy-Related Balances Other policy-related balances include policy and contract claims, premiums received in advance, unearned revenue (“UREV”) liabilities, obligations assumed under structured settlement assignments, policyholder dividends due and unpaid and policyholder dividends left on deposit. The liability for policy and contract claims generally relates to incurred but not reported (“IBNR”) death and dental claims. In addition, generally included in other policy-related balances are claims which have been reported but not yet settled for death and dental . The liability for these claims is based on the Company’s estimated ultimate cost of settling all claims. The Company derives estimates for the development of IBNR claims principally from analyses of historical patterns of claims by business line. The methods used to determine these estimates are continually reviewed. Adjustments resulting from this continuous review process and differences between estimates and payments for claims are recognized in policyholder benefits and claims expense in the period in which the estimates are changed or payments are made. The Company accounts for the prepayment of premiums on its individual life, group life and health contracts as premiums received in advance. These amounts are then recognized in premiums when due. The UREV liability relates to universal life and investment-type products and represents policy charges for services to be provided in future periods. The charges are deferred as unearned revenue and amortized on a basis consistent with the methodologies and assumptions used for amortizing deferred policy acquisition costs (“DAC”) for the related contracts. Changes in the UREV liability for each period (representing deferrals less amortization) are reported in universal life and investment-type product policy fees. Recognition of Insurance Revenues and Deposits Premiums related to whole and term life products, individual disability, individual and group fixed annuities (including pension risk transfers, certain structured settlements and certain income annuities), long-term care and participating products are recognized as revenues when due from policyholders. Policyholder benefits and expenses are provided to recognize profits over the estimated lives of the insurance policies. When premiums are due over a significantly shorter period than the period over which benefits are provided, any excess profit is deferred as a DPL and recognized into earnings in a constant relationship to insurance in-force or, for annuities, the present value of expected future policy benefit payments. Premiums related to short-duration non-medical health and disability contracts are recognized on a pro rata basis over the applicable contract term. Unearned premiums, representing the portion of premium written related to the unexpired coverage, are reflected as liabilities until earned. Deposits related to universal life and investment-type products are credited to PABs. Revenues from such contracts consist of fees for mortality, policy administration and surrender charges and are recorded in universal life and investment-type product policy fees in the period in which services are provided. All fees due from contractholders in excess of the attributed fees on contracts with MRBs are reported in universal life and investment-type product policy fees. Amounts that are charged to earnings include interest credited and benefit claims incurred in excess of related PABs. All revenues and expenses are presented net of reinsurance, as applicable. Deferred Policy Acquisition Costs, Value of Business Acquired and Other Intangibles The Company incurs significant costs in connection with acquiring new and renewal insurance business. Costs that are related directly to the successful acquisition or renewal of insurance contracts are capitalized as DAC. Such costs include: • incremental direct costs of contract acquisition, such as commissions; • the portion of an employee’s total compensation and benefits related to time spent selling, underwriting or processing the issuance of new and renewal insurance business only with respect to actual policies acquired or renewed; and • other essential direct costs that would not have been incurred had a policy not been acquired or renewed. All other acquisition-related costs, including those related to general advertising and solicitation, market research, agent training, product development, unsuccessful sales and underwriting efforts, as well as all indirect costs, are expensed as incurred. Value of business acquired (“VOBA”) is an intangible asset resulting from a business combination that represents the excess of book value over the estimated fair value of acquired insurance, annuity, and investment-type contracts in-force at the acquisition date. The estimated fair value of the acquired liabilities is based on projections, by each block of business, of future policy and contract charges, premiums, mortality and morbidity, separate account performance, surrenders, operating expenses, investment returns, nonperformance risk adjustment and other factors. Actual experience with the purchased business may vary from these projections. VOBA is subject to periodic recoverability testing for traditional life and limited-payment contracts, as well as universal life type contracts. Beginning on the Transition Date, DAC and VOBA for most long-duration products are amortized on a constant-level basis that approximates straight-line amortization on an individual contract basis. The DAC and VOBA related to U.S. annuities are amortized over expected benefit payments, and for all other long-duration products are generally amortized in proportion to policy count. For short-duration products, DAC and VOBA are amortized in proportion to actual and expected future earned premiums. DAC and VOBA are aggregated on the financial statements for reporting purposes. See Note 7 for additional information on DAC and VOBA amortization. Amortization of DAC and VOBA is included in other expenses. The Company generally has two different types of sales inducements which are included in other assets: (i) the policyholder receives a bonus whereby the policyholder’s initial account balance is increased by an amount equal to a specified percentage of the customer’s deposit; and (ii) the policyholder receives a higher interest rate using a dollar cost averaging method than would have been received based on the normal general account interest rate credited. The Company defers sales inducements and amortizes them over the life of the policy using the same methodologies and assumptions used to amortize DAC for the related contracts. The amortization of sales inducements is included in policyholder benefits and claims. Each year, or more frequently if circumstances indicate a potential recoverability issue exists, the Company reviews deferred sales inducements (“DSI”) to determine the recoverability of the asset. DSI assets were $46 million and $49 million at September 30, 2023 and December 31, 2022, respectively. Value of distribution agreements acquired (“VODA”) is reported in other assets and represents the present value of expected future profits associated with the expected future business derived from the distribution agreements acquired as part of a business combination. Value of customer relationships acquired (“VOCRA”) is also reported in other assets and represents the present value of the expected future profits associated with the expected future business acquired through existing customers of the acquired company or business. The VODA and VOCRA associated with past business combinations are amortized over the assets’ useful lives ranging from 10 to 30 years and such amortization is included in other expenses. Each year, or more frequently if circumstances indicate a possible impairment exists, the Company reviews VODA and VOCRA to determine whether the asset is impaired. Reinsurance For each of its reinsurance agreements, the Company determines whether the agreement provides indemnification against loss or liability relating to insurance risk in accordance with applicable accounting standards. Cessions under reinsurance agreements do not discharge the Company’s obligations as the primary insurer. The Company reviews all contractual features, including those that may limit the amount of insurance risk to which the reinsurer is subject or features that delay the timely reimbursement of claims. The reinsurance recoverable for traditional non-participating and limited-payment contracts is generally measured using a net premium methodology to accrue the projected net gain or loss on reinsurance in proportion to the gross premiums of the underlying reinsured cohorts; and is updated retrospectively on a quarterly basis for actual experience and at least once a year for any changes in cash flow assumptions. The locked-in discount rate used to measure changes in the reinsurance recoverable recorded in net income was established at the Transition Date, or at the inception of the reinsurance coverage for new reinsurance agreements entered into subsequent to the Transition Date. The reinsurance recoverable is remeasured to an upper-medium grade discount rate through OCI at each reporting date, similar to the underlying reinsured contracts. The reinsurance recoverable for other long-duration contracts and associated contract features is measured using assumptions and methods generally consistent with the underlying direct policies. For reinsurance of existing in-force blocks of long-duration contracts that transfer significant insurance risk, the difference, if any, between the amounts paid (received), and the liabilities ceded (assumed) related to the underlying reinsured contracts is considered the net cost of reinsurance at the inception of the reinsurance agreement. The net cost of reinsurance is amortized on a basis consistent with the methodologies and assumptions used for amortizing DAC related to the underlying reinsured contracts. Subsequent amounts paid (received) on the reinsurance of in-force blocks, as well as amounts paid (received) related to new business, are recorded as ceded (assumed) premiums; and ceded (assumed) premiums, reinsurance and other receivables (future policy benefits) are established. For prospective reinsurance of short-duration contracts that meet the criteria for reinsurance accounting, amounts paid (received) are recorded as ceded (assumed) premiums and ceded (assumed) unearned premiums. Ceded (assumed) unearned premiums are reflected as a component of premiums, reinsurance and other receivables (future policy benefits). Such amounts are amortized through earned premiums over the remaining contract period in proportion to the amount of insurance protection provided. For retroactive reinsurance of short-duration contracts that meet the criteria for reinsurance accounting, amounts paid (received) in excess of the related insurance liabilities ceded (assumed) are recognized immediately as a loss and are reported in the appropriate line item within the statement of operations. Any gain on such retroactive agreement is deferred and is amortized as part of DAC, primarily using the recovery method. Amounts currently recoverable under reinsurance agreements are included in premiums, reinsurance and other receivables and amounts currently payable are included in other liabilities. Assets and liabilities relating to reinsurance agreements with the same reinsurer may be recorded net on the balance sheet, if a right of offset exists within the reinsurance agreement. In the event that reinsurers do not meet their obligations to the Company under the terms of the reinsurance agreements, or when events or changes in circumstances indicate that its carrying amount may not be recoverable, reinsurance recoverable balances could become uncollectible. In such instances, reinsurance recoverable balances are stated net of allowances for uncollectible reinsurance, consistent with credit loss guidance which requires recording an allowance for credit loss (“ACL”). The funds withheld liability represents amounts withheld by the Company in accordance with the terms of the reinsurance agreements. The Company withholds the funds rather than transferring the underlying investments and, as a result, records funds withheld liability within other liabilities. The Company recognizes interest on funds withheld, included in other expenses, at rates defined by the terms of the agreement which may be contractually specified or directly related to the investment portfolio. See Note 1 of the Notes to the Consolidated Financial Statements included in the 2022 Annual Report for information on funds withheld assets. Premiums, fees and policyholder benefits and claims include amounts assumed under reinsurance agreements and are net of reinsurance ceded. Amounts received from reinsurers for policy administration are reported in other expenses. If the Company determines that a reinsurance agreement does not expose the reinsurer to a reasonable possibility of a significant loss from insurance risk, the Company records the agreement using the deposit method of accounting. Deposits received are inclu

Segment Reporting [Abstract]
Segment Information	2. Segment Information The Company is organized into two segments: U.S. and MetLife Holdings. In addition, the Company reports certain of its results of operations in Corporate & Other. U.S. The U.S. segment offers a broad range of protection products and services aimed at serving the financial needs of customers throughout their lives. These products are sold to corporations and their respective employees, other institutions and their respective members, as well as individuals. The U.S. segment is organized into two businesses: Group Benefits and Retirement and Income Solutions (“RIS”). • The Group Benefits business offers products such as term, variable and universal life insurance, dental, group and individual disability and accident & health insurance. • The RIS business offers a broad range of life and annuity-based insurance and investment products, including 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. 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 affiliated reinsurance and 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. The adoption of LDTI impacted the Company’s calculation of adjusted earnings. With the adoption of LDTI, the measurement model was simplified for DAC and VOBA, and most embedded derivatives were reclassified as MRBs. As a result, the Company updated its calculation of adjusted earnings to remove certain adjustments related to the amortization of DAC, VOBA and related intangibles and adjusted for changes in measurement of certain guarantees. Under LDTI, adjusted earnings excludes changes in fair value associated with MRBs, changes in discount rates on certain annuitization guarantees, losses at contract inception for certain single premium business, and asymmetrical accounting associated with in-force reinsurance. All periods presented herein reflect the updated calculation of adjusted earnings. 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), MRB 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. • Policyholder benefits and claims excludes (i) amortization of basis adjustments associated with de-designated fair value hedges of future policy benefits, (ii) inflation-indexed benefit adjustments associated with contracts backed by inflation-indexed investments, and (iii) 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 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. 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 nine months ended September 30, 2023 and 2022. 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. The adoption of LDTI resulted in changes to the economic capital model. The changes related to this adoption do not represent a change in the composition of the segments and, in accordance with GAAP guidance for segment reporting, the Company will apply the changes to the economic capital model prospectively and did not update the economic model for 2022 and 2021. 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. With the adoption of LDTI, net investment income was reallocated for certain segments to reflect the impact of the change to certain liability balances, with no impact to consolidated net investment income. 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.

Liability for Future Policy Benefits and Unpaid Claims Disclosure	3. Future Policy BenefitsThe Company establishes liabilities for amounts payable under insurance policies. These liabilities are comprised of traditional and limited-payment contracts and associated DPLs, additional insurance liabilities, participating life and short-duration contracts. The LDTI transition adjustments related to traditional and limited-payment contracts, DPLs, and additional insurance liabilities, as well as the associated ceded recoverables, as described in Note 1, were as follows at the Transition Date: U.S. MetLife Holdings MetLife Holdings Other Long-Duration Short-Duration and Other Total (In millions) Balance, future policy benefits, at December 31, 2020 $ 54,535 $ 14,281 $ 45,349 $ 9,625 $ 10,131 $ 133,921 Removal of additional insurance liabilities for separate presentation (1) (4) — — (2,925) — (2,929) Subtotal - pre-adoption balance, excluding additional liabilities 54,531 14,281 45,349 6,700 10,131 130,992 Removal of related amounts in AOCI (5,571) (1,210) — (54) — (6,835) Adjustment of future policy benefits to remeasure cohorts where net premiums exceed gross premiums under the modified retrospective approach 41 — — 48 — 89 Effect of remeasurement of future policy benefits to an upper-medium grade discount rate 15,011 8,270 — 1,927 — 25,208 Other balance sheet reclassifications and adjustments upon adoption of the LDTI standard (4,747) — — (47) — (4,794) Removal of remeasured deferred profit liabilities for separate presentation (1) (2,413) — — (250) — (2,663) Balance, traditional and limited-payment contracts, at January 1, 2021 $ 56,852 $ 21,341 $ 45,349 $ 8,324 $ 10,131 $ 141,997 Balance, deferred profit liabilities at January 1, 2021 $ 2,413 $ — $ — $ 250 $ — $ 2,663 Balance, ceded recoverables on traditional and limited-payment contracts at December 31, 2020 $ 203 $ — $ 752 $ 955 Effect of remeasurement of the ceded recoverable to an upper-medium grade discount rate 135 — 268 403 Adjustments for loss contracts (with net premiums in excess of gross premiums) under the modified retrospective approach — — 32 32 Adjustments for the cumulative effect of adoption on ceded recoverables on traditional and limited-payment contract 6 — 20 26 Balance ceded recoverables on traditional and limited-payment contracts at January 1, 2021 $ 344 $ — $ 1,072 $ 1,416 __________________ (1) LDTI requires separate disaggregated rollforwards of the additional insurance liabilities balance and the traditional and limited-payment FPBs. Therefore, the additional insurance liabilities and DPL amounts that are recorded in the FPB financial statement line item are removed to derive the opening balance of traditional and limited-payment contracts at the Transition Date.

Rollforwards - Traditional and Limited-Payment Contracts The following information about the direct and assumed liability for future policy benefits includes disaggregated rollforwards of expected future net premiums and expected future benefits. 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 adjusted balance in each disaggregated rollforward reflects the remeasurement (gains) losses. U.S. - Annuities The U.S. segment’s annuities products include pension risk transfers, certain structured settlements and certain institutional income annuities, which are mainly single premium spread-based products. Information regarding these products was as follows: Nine Months 2023 2022 (Dollars in millions) Present Value of Expected Net Premiums Balance, beginning of period, at current discount rate at balance sheet date $ — $ — Balance, beginning of period, at original discount rate $ — $ — Effect of changes in cash flow assumptions (1) — — Effect of actual variances from expected experience (2) (44) — Adjusted balance (44) — Issuances 290 8,272 Net premiums collected (246) (8,272) Ending balance at original discount rate — — Balance, end of period, at current discount rate at balance sheet date $ — $ — Present Value of Expected Future Policy Benefits Balance, beginning of period, at current discount rate at balance sheet date $ 48,190 $ 54,172 Balance, beginning of period, at original discount rate $ 49,194 $ 42,453 Effect of changes in cash flow assumptions (1) (193) (99) Effect of actual variances from expected experience (2) (370) (120) Adjusted balance 48,631 42,234 Issuances 294 8,370 Interest accrual 1,785 1,574 Benefit payments (3,480) (2,728) Ending balance at original discount rate 47,230 49,450 Effect of changes in discount rate assumptions (3,053) (2,372) Balance, end of period, at current discount rate at balance sheet date 44,177 47,078 Cumulative amount of fair value hedging adjustments (431) (169) Net liability for future policy benefits 43,746 46,909 Less: Reinsurance recoverables — — Net liability for future policy benefits, net of reinsurance $ 43,746 $ 46,909 Undiscounted - Expected future benefit payments $ 92,052 $ 96,089 Discounted - Expected future benefit payments (at current discount rate at balance sheet date) $ 44,177 $ 47,078 Weighted-average duration of the liability 9 years 9 years Weighted-average interest accretion (original locked-in) rate 5.1 % 4.7 % Weighted-average current discount rate at balance sheet date 6.1 % 5.8 % __________________ (1) For the nine months ended September 30, 2023, the net effect of changes in cash flow assumptions was largely offset by the corresponding impact in DPL associated with the U.S. segment’s annuities products of $136 million. For the nine months ended September 30, 2022, the net effect of changes in cash flow assumptions was more than offset by the corresponding impact in DPL associated with the U.S. segment’s annuities products of $113 million. (2) For the nine months ended September 30, 2023, the net effect of actual variances from expected experience was largely offset by the corresponding impact in DPL associated with the U.S. segment’s annuities products of $243 million. For the nine months ended September 30, 2022, the net effect of actual variances from expected experience was partially offset by the corresponding impact in DPL associated with the U.S. segment’s annuities products of $48 million. Significant Methodologies and Assumptions The principal inputs used in the establishment of the FPB for the U.S. segment’s annuities products include actual premiums, actual benefits, in-force data, locked-in claim-related expense, the locked-in interest accretion rate, the current upper-medium grade discount rate at the balance sheet date and best estimate mortality assumptions. For the nine months ended September 30, 2023 and 2022, the net effect of changes in cash flow assumptions was primarily driven by updates in biometric assumptions related to mortality. For the nine months ended September 30, 2023, the net effect of actual variances from expected experience was primarily driven by favorable mortality and the amendment of an affiliated reinsurance treaty. For the nine months ended September 30, 2022, the net effect of actual variances from expected experience was primarily driven by favorable mortality. When single-premium annuity contracts are issued, the FPB reserve is required to be measured at an upper-medium grade discount rate. Due to differences between the upper-medium grade discount rate and pricing assumptions used to determine the contractual premium, the initial FPB reserve at issue for a particular cohort may be greater than the contractual premium received, and the difference must be recognized as an immediate loss at issue. On these cohorts, future experience that differs from expected experience and changes in cash flow assumptions result in the recognition of remeasurement gains and losses with net remeasurement gains limited to the amount of the original loss at issue, after which any favorable experience is deferred and recorded within the DPL. For the three months ended September 30, 2022, the Company incurred a loss at issue of $91 million and recognized a net remeasurement loss of $41 million attributable to cohorts with no DPL or where the DPL was depleted during the period. For the nine months ended September 30, 2022, the Company incurred a loss at issue of $91 million and recognized a net remeasurement loss of $6 million attributable to cohorts with no DPL or where the DPL was depleted during the period. MetLife Holdings - Long-term Care The MetLife Holdings segment’s long-term care products offer protection against potentially high costs of long-term health care services. Information regarding these products was as follows: Nine Months 2023 2022 (Dollars in millions) Present Value of Expected Net Premiums Balance, beginning of period, at current discount rate at balance sheet date $ 5,775 $ 7,058 Balance, beginning of period, at original discount rate $ 5,807 $ 5,699 Effect of changes in cash flow assumptions (152) 272 Effect of actual variances from expected experience 173 101 Adjusted balance 5,828 6,072 Interest accrual 222 223 Net premiums collected (438) (434) Ending balance at original discount rate 5,612 5,861 Effect of changes in discount rate assumptions (258) (142) Balance, end of period, at current discount rate at balance sheet date $ 5,354 $ 5,719 Present Value of Expected Future Policy Benefits Balance, beginning of period, at current discount rate at balance sheet date $ 19,619 $ 27,627 Balance, beginning of period, at original discount rate $ 20,165 $ 19,406 Effect of changes in cash flow assumptions (190) 301 Effect of actual variances from expected experience 194 100 Adjusted balance 20,169 19,807 Interest accrual 801 778 Benefit payments (579) (522) Ending balance at original discount rate 20,391 20,063 Effect of changes in discount rate assumptions (2,012) (1,358) Balance, end of period, at current discount rate at balance sheet date 18,379 18,705 Net liability for future policy benefits $ 13,025 $ 12,986 Undiscounted: Expected future gross premiums $ 10,713 $ 11,335 Expected future benefit payments $ 45,152 $ 46,011 Discounted (at current discount rate at balance sheet date): Expected future gross premiums $ 6,714 $ 7,126 Expected future benefit payments $ 18,379 $ 18,705 Weighted-average duration of the liability 14 years 15 years Weighted -average interest accretion (original locked-in) rate 5.5 % 5.5 % Weighted-average current discount rate at balance sheet date 6.3 % 6.0 % Significant Methodologies and Assumptions The principal inputs used in the establishment of the FPB reserve for long-term care products include actual premiums, actual benefits, in-force data, locked-in claim-related expense, the locked-in interest accretion rate, current upper-medium grade discount rate at the balance sheet date and best estimate assumptions. The best estimate assumptions include mortality, lapse, incidence, claim utilization, claim cost inflation, claim continuance, and premium rate increases. Rollforward - Additional Insurance Liabilities The Company establishes additional insurance liabilities for annuitization, death or other insurance benefits for universal life and variable universal life contract features where the Company guarantees to the contractholder either a secondary guarantee or a guaranteed paid-up benefit. The policy can remain in force, even if the base policy account value is zero, as long as contractual secondary guarantee requirements have been met. The following information about the direct liability for additional insurance liabilities includes a disaggregated rollforward. The products grouped within the rollforward were selected based upon common characteristics and valuations using similar inputs, judgments, assumptions and methodologies within a particular segment of the business. The adjusted balance in each disaggregated rollforward reflects the remeasurement (gains) losses. MetLife Holdings The MetLife Holdings segment’s universal life and variable universal life products offer a contract feature where the Company guarantees to the contractholder a secondary guarantee or a guaranteed paid-up benefit. Information regarding these additional insurance liabilities was as follows: Nine Months 2023 2022 Universal and Variable Universal Life (Dollars in millions) Balance, beginning of period $ 1,642 $ 1,623 Less: AOCI adjustment (63) 66 Balance, beginning of period, before AOCI adjustment 1,705 1,557 Effect of changes in cash flow assumptions 25 18 Effect of actual variances from expected experience 9 21 Adjusted balance 1,739 1,596 Assessments accrual 70 67 Interest accrual 67 61 Excess benefits paid (56) (51) Balance, end of period, before AOCI adjustment 1,820 1,673 Add: AOCI adjustment (65) (66) Balance, end of period 1,755 1,607 Less: Reinsurance recoverables 659 618 Balance, end of period, net of reinsurance $ 1,096 $ 989 Weighted-average duration of the liability 17 years 18 years Weighted-average interest accretion rate 5.2 % 5.2 % Significant Methodologies and Assumptions Liabilities for ULSG and paid-up guarantees are determined by estimating the expected value of death benefits payable when the account balance is projected to be zero and recognizing those benefits ratably over the life of the contract based on total expected assessments. The Company’s revenue and interest recognized in the interim condensed consolidated statements of operations and comprehensive income (loss) for long-duration contracts, excluding MetLife Holdings’ participating life contracts, were as follows: Nine Months 2023 2022 Gross Premiums or Assessments (1) Interest Expense (2) Gross Premiums or Assessments (1) Interest Expense (2) (In millions) Traditional and Limited-Payment Contracts: U.S. - Annuities $ 221 $ 1,785 $ 8,291 $ 1,574 MetLife Holdings - Long-term care 547 579 550 555 Deferred Profit Liabilities: U.S. - Annuities N/A 107 N/A 102 Additional Insurance Liabilities: MetLife Holdings - Universal and variable universal life 347 67 356 61 Other long duration 671 227 532 226 Total $ 1,786 $ 2,765 $ 9,729 $ 2,518 __________________ (1) Gross premiums are related to traditional and limited-payment contracts and are included in premiums.

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) Included is the covariance impact from aggregating the market observable inputs, mostly driven by interest rate and capital market volatility. Information regarding the Company’s net amount at risk, excluding offsets from hedging, and the weighted-average attained age of the contractholder for the MetLife Holdings segment’s annuities products was as follows at: September 30, 2023 2022 In the Event of Death (1) At Annuitization or Exercise of Other Living Benefits (2) In the Event of Death (1) At Annuitization or Exercise of Other Living Benefits (2) (Dollars in millions) Net amount at risk (3) $ 3,970 $ 880 $ 5,188 $ 1,309 Weighted-average attained age of contractholders 70 years 70 years 69 years 69 years __________________ (1) For those guarantees of benefits that are payable in the event of death, the net amount at risk is generally defined as the current guaranteed minimum death benefit in excess of the current account balance at the balance sheet date. It represents the amount of the claim that the Company would incur if death claims were filed on all contracts at the balance sheet date. (2) For benefits that are payable in the event of annuitization or exercise of other living benefits, the net amount at risk is generally defined as the amount (if any) that would be required to be added to the total account value to purchase a lifetime income stream, based on current annuity rates or to provide other living benefits. This amount represents the Company’s potential economic exposure in the event all contractholders were to annuitize or to exercise other living benefits at the balance sheet date. (3) Includes amounts for certain variable annuities with guarantees, which are also disclosed in “MetLife Holdings – Annuities” in Note 4, due to contracts recorded as PABs, along with related guarantees recorded as MRBs. 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 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, but not limited to, 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.

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, but not limited to, 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.

Closed Block

Closed Block Disclosure [Abstract]
Closed Block	8. Closed BlockOn 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. Assets have been allocated to the closed block in an amount that has been determined to produce cash flows which, together with anticipated revenues from the policies included in the closed block, are reasonably expected to be sufficient to support obligations and liabilities relating to these policies, including, but not limited to, provisions for the payment of claims and certain expenses and taxes, and to provide for the continuation of policyholder dividend scales in effect for 1999, if the experience underlying such dividend scales continues, and for appropriate adjustments in such scales if the experience changes. At least annually, the Company compares actual and projected experience against the experience assumed in the then-current dividend scales. Dividend scales are adjusted periodically to give effect to changes in experience. The closed block assets, the cash flows generated by the closed block assets and the anticipated revenues from the policies in the closed block will benefit only the holders of the policies in the closed block. To the extent that, over time, cash flows from the assets allocated to the closed block and claims and other experience related to the closed block are, in the aggregate, more or less favorable than what was assumed when the closed block was established, total dividends paid to closed block policyholders in the future may be greater than or less than the total dividends that would have been paid to these policyholders if the policyholder dividend scales in effect for 1999 had been continued. Any cash flows in excess of amounts assumed will be available for distribution over time to closed block policyholders and will not be available to stockholders. If the closed block has insufficient funds to make guaranteed policy benefit payments, such payments will be made from assets outside of the closed block. The closed block will continue in effect as long as any policy in the closed block remains in-force. The expected life of the closed block is over 100 years from the Demutualization Date. The Company uses the same accounting principles to account for the participating policies included in the closed block as it used prior to the Demutualization Date. However, the Company establishes a policyholder dividend obligation for earnings that will be paid to policyholders as additional dividends as described below. The excess of closed block liabilities over closed block assets at the Demutualization Date (adjusted to eliminate the impact of related amounts in AOCI) represents the estimated maximum future earnings from the closed block expected to result from operations, attributed net of income tax, to the closed block. Earnings of the closed block are recognized in income over the period the policies and contracts in the closed block remain in-force. If, over the period the closed block remains in existence, the actual cumulative earnings of the closed block are greater than the expected cumulative earnings of the closed block, the Company will pay the excess to closed block policyholders as additional policyholder dividends unless offset by future unfavorable experience of the closed block and, accordingly, will recognize only the expected cumulative earnings in income with the excess recorded as a policyholder dividend obligation. If over such period, the actual cumulative earnings of the closed block are less than the expected cumulative earnings of the closed block, the Company will recognize only the actual earnings in income. However, the Company may change policyholder dividend scales in the future, which would be intended to increase future actual earnings until the actual cumulative earnings equal the expected cumulative earnings. At least annually, management performs a premium deficiency test using best estimate assumptions to determine whether the projected future earnings of the closed block are sufficient to support the payment of future closed block contractual benefits. The most recent deficiency test demonstrated that the projected future earnings of the closed block are sufficient to support the payment of future closed block contractual benefits. 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. 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.

Inherent in management’s evaluation of the security are assumptions and estimates about the operations of the issuer and its future earnings potential. Considerations used in the credit loss evaluation process include, but are not limited to: (i) the extent to which the estimated fair value has been below amortized cost, (ii) adverse conditions specifically related to a security, an industry sector or sub-sector, or an economically depressed geographic area, adverse change in the financial condition of the issuer of the security, changes in technology, discontinuance of a segment of the business that may affect future earnings, and changes in the quality of credit enhancement, (iii) payment structure of the security and likelihood of the issuer being able to make payments, (iv) failure of the issuer to make scheduled interest and principal payments, (v) whether the issuer, or series of issuers or an industry has suffered a catastrophic loss or has exhausted natural resources, (vi) whether the Company has the intent to sell or will more likely than not be required to sell, including transfers in connection with reinsurance transactions, a particular security before the decline in estimated fair value below amortized cost recovers, (vii) with respect to Structured Products, changes in forecasted cash flows after considering the changes in the financial condition of the underlying loan obligors and quality of underlying collateral, expected prepayment speeds, current and forecasted loss severity, consideration of the payment terms of the underlying assets backing a particular security, and the payment priority within the tranche structure of the security, (viii) changes in the rating of the security by a rating agency, and (ix) other subjective factors, including concentrations and information obtained from regulators. The methodology and significant inputs used to determine the amount of credit loss are as follows: • The Company calculates the recovery value by performing a discounted cash flow analysis based on the present value of future cash flows. The discount rate is generally the effective interest rate of the security at the time of purchase for fixed-rate securities and the spot rate at the date of evaluation of credit loss for floating-rate securities. • When determining collectability and the period over which value is expected to recover, the Company applies considerations utilized in its overall credit loss evaluation process which incorporates information regarding the specific security, fundamentals of the industry and geographic area in which the security issuer operates, and overall macroeconomic conditions. Projected future cash flows are estimated using assumptions derived from management’s single best estimate, the most likely outcome in a range of possible outcomes, after giving consideration to a variety of variables that include, but are not limited to: payment terms of the security; the likelihood that the issuer can service the interest and principal payments; the quality and amount of any credit enhancements; the security’s position within the capital structure of the issuer; possible corporate restructurings or asset sales by the issuer; any private and public sector programs to restructure foreign government securities and municipals; and changes to the rating of the security or the issuer by rating agencies. • Additional considerations are made when assessing the unique features that apply to certain Structured Products including, but not limited to: the quality of underlying collateral, historical performance of the underlying loan obligors, historical rent and vacancy levels, changes in the financial condition of the underlying loan obligors, expected prepayment speeds, current and forecasted loss severity, consideration of the payment terms of the underlying loans or assets backing a particular security, changes in the quality of credit enhancement and the payment priority within the tranche structure of the security. With respect to securities that have attributes of debt and equity (“perpetual hybrid securities”), consideration is given in the credit loss analysis as to whether there has been any deterioration in the credit of the issuer and the likelihood of recovery in value of the securities that are in a severe unrealized loss position. Consideration is also given as to whether any perpetual hybrid securities with an unrealized loss, regardless of credit rating, have deferred any dividend payments. In periods subsequent to the recognition of an initial ACL on a security, the Company reassesses credit loss quarterly. Subsequent increases or decreases in the expected cash flow from the security result in corresponding decreases or increases in the ACL which are recognized in earnings and reported within net investment gains (losses); however, the previously recorded ACL is not reduced to an amount below zero. Full or partial write-offs are deducted from the ACL in the period the security, or a portion thereof, is considered uncollectible. Recoveries of amounts previously written off are recorded to the ACL in the period received. When the Company has the intent-to-sell the security or it is more likely than not that the Company will be required to sell the security before recovery of its amortized cost, any ACL is written off and the amortized cost is written down to estimated fair value through a charge within net investment gains (losses), which becomes the new amortized cost of the security. Evaluation of Fixed Maturity Securities AFS in an Unrealized Loss Position Gross unrealized losses on securities without an ACL increased $2.7 billion for the nine months ended September 30, 2023 to $19.2 billion primarily due to increases in interest rates and the impact of weakening foreign currencies on certain non-functional currency denominated fixed maturity securities, partially offset by impairments in connection with a pending reinsurance transaction, and narrowing credit spreads. Gross unrealized losses on securities without an ACL that have been in a continuous gross unrealized loss position for 12 months or greater were $16.9 billion at September 30, 2023, or 88% of the total gross unrealized losses on securities without an ACL. Investment Grade Fixed Maturity Securities AFS Of the $16.9 billion of gross unrealized losses on securities without an ACL that have been in a continuous gross unrealized loss position for 12 months or greater, $16.2 billion, or 96%, were related to 8,032 investment grade securities. Unrealized losses on investment grade securities are principally related to widening credit spreads since purchase and, with respect to fixed-rate securities, rising interest rates since purchase. Below Investment Grade Fixed Maturity Securities AFS Of the $16.9 billion of gross unrealized losses on securities without an ACL that have been in a continuous gross unrealized loss position for 12 months or greater, $678 million, or 4%, were related to 718 below investment grade securities. Unrealized losses on below investment grade securities are principally related to foreign corporate and U.S. corporate securities (primarily consumer, transportation and communications). 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, as well as with respect to fixed-rate securities, rising interest rates since purchase. Management evaluates U.S. corporate and foreign corporate securities based on several factors such as expected cash flows, financial condition and near-term and long-term prospects of the issuers. Current Period Evaluation At September 30, 2023, with respect to securities in an unrealized loss position without an ACL, the Company did not intend to sell these securities, 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. Based on the Company’s current evaluation of its securities in an unrealized loss position without an ACL, the Company concluded that these securities had not incurred a credit loss and should not have an ACL at September 30, 2023. Future provisions for credit loss will depend primarily on economic fundamentals, issuer performance (including changes in the present value of future cash flows expected to be collected), changes in credit ratings and collateral valuation.

See Note 1. The amount of net (discounts) premiums and deferred (fees) expenses, included within total amortized cost, primarily attributable to residential mortgage loans was ($720) million and ($717) million at September 30, 2023 and December 31, 2022, respectively. The accrued interest income excluded from total amortized cost for commercial, agricultural and residential mortgage loans at September 30, 2023 was $189 million, $147 million and $78 million, respectively. The accrued interest income excluded from total amortized cost for commercial, agricultural and residential mortgage loans at December 31, 2022 was $171 million, $147 million and $70 million, respectively. Purchases of mortgage loans, from unaffiliated parties, consisting primarily of residential mortgage loans, were $118 million and $975 million for the three months and nine months ended September 30, 2023, respectively, and $182 million and $1.3 billion for the three months and nine months ended September 30, 2022, respectively. During the second quarter of 2023, the Company assigned mortgage loans with a previously recorded amortized cost of $5.3 billion to its affiliated mortgage origination company, which is wholly-owned by MetLife. In connection with the assignment, this affiliate contemporaneously assumed the Company’s rights and obligations associated with the assigned mortgage loans. In exchange, the Company received $5.3 billion of mortgage secured loans from this affiliate, secured by the same mortgage loans assigned. As of September 30, 2023, the Company’s aggregate participation interest in affiliated mortgage secured loans included in commercial and agricultural mortgage loans was $12.9 billion. In addition, see “— Related Party Investment Transactions” for information regarding transfers of mortgage loans from affiliates. Rollforward of Allowance for Credit Loss for Mortgage Loans by Portfolio Segment The rollforward of ACL for mortgage loans, by portfolio segment, is as follows: Nine Months Ended September 30, 2023 2022 Commercial Agricultural Residential Total Commercial Agricultural Residential Total (In millions) Balance, beginning of period $ 174 $ 105 $ 169 $ 448 $ 260 $ 79 $ 197 $ 536 Provision (release) 42 50 (11) 81 (8) 48 (77) (37) Charge-offs, net of recoveries (10) (13) — (23) (83) (22) (2) (107) Balance, end of period $ 206 $ 142 $ 158 $ 506 $ 169 $ 105 $ 118 $ 392 Allowance for Credit Loss Methodology The Company records an allowance for expected lifetime credit loss in earnings within net investment gains (losses) in an amount that represents the portion of the amortized cost basis of mortgage loans that the Company does not expect to collect, resulting in mortgage loans being presented at the net amount expected to be collected. In determining the Company’s ACL, management applies significant judgment to estimate expected lifetime credit loss, including: (i) pooling mortgage loans that share similar risk characteristics, (ii) considering expected lifetime credit loss over the contractual term of its mortgage loans adjusted for expected prepayments and any extensions, and (iii) considering past events and current and forecasted economic conditions. Each of the Company’s commercial, agricultural and residential mortgage loan portfolio segments are evaluated separately. The ACL is calculated for each mortgage loan portfolio segment based on inputs unique to each loan portfolio segment. On a quarterly basis, mortgage loans within a portfolio segment that share similar risk characteristics, such as internal risk ratings or consumer credit scores, are pooled for calculation of ACL. On an ongoing basis, mortgage loans with dissimilar risk characteristics (i.e., loans with significant declines in credit quality), such as collateral dependent mortgage loans (i.e., when the borrower is experiencing financial difficulty, including when foreclosure is reasonably possible or probable), are evaluated individually for credit loss. The ACL for loans evaluated individually are established using the same methodologies for all three portfolio segments. For example, the ACL for a collateral dependent loan is established as the excess of amortized cost over the estimated fair value of the loan’s underlying collateral, less selling cost when foreclosure is probable. Accordingly, the change in the estimated fair value of collateral dependent loans, which are evaluated individually for credit loss, is recorded as a change in the ACL which is recorded on a quarterly basis as a charge or credit to earnings in net investment gains (losses). Mortgage loans to be disposed of in connection with a pending reinsurance transaction are carried at the lower of amortized cost or estimated fair value. 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. Commitments to lend: After 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 are 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 where the borrower was determined to be experiencing financial difficulties and the mortgage loans were modified by any of the following means, principal forgiveness, interest rate reduction, other-than-insignificant payment delay or term extension. The amount, timing and extent of modifications granted are considered in determining any ACL recorded. Commercial mortgage loans: For the three months ended September 30, 2023, the Company granted a short-term extension on a loan with an amortized cost of $135 million. In addition, the Company further extended the term of a loan modified in the first and second quarters of 2023 by an additional two months. These modifications added a weighted-average of less than one year to the life of the modified loans. These modified loans represent less than 1% of the portfolio segment. For the nine months ended September 30, 2023, the Company granted term extensions on loans with an amortized cost of $315 million. These modifications added a weighted-average of less than one year to the life of the modified loans. These modified loans represent less than 1% of the portfolio segment. Residential mortgage loans: For the three months ended September 30, 2023, the Company granted term extensions on loans with an amortized cost of $1 million, other-than-insignificant payment delays on loans with an amortized cost of $7 million, and term extensions and other-than-insignificant payment delays on loans with an amortized cost of $6 million. These modified loans represent less than 1% of the portfolio segment. These loan modifications added a weighted-average of eight years to the life of the modified loans. For the nine months ended September 30, 2023, the Company granted term extensions on loans with an amortized cost of $6 million, other-than-insignificant payment delays on loans with an amortized cost of $12 million, term extensions and other-than-insignificant payment delays on loans with an amortized cost of $15 million and term extensions, other-than-insignificant payment delays and interest rate reductions on loans with an amortized cost of $4 million. These modified loans represent less than 1% of the portfolio segment. These loan modifications added a weighted-average of nine years to the life of the modified loans, capitalized or deferred amounts due and reduced the weighted-average interest rate of the modified loans from 5.8% to 4.2%. For both the three months and nine months ended September 30, 2023, the Company did not have a significant amount of mortgage loans that were modified to borrowers experiencing financial difficulty that were not considered current.

Derivatives Accounting for Derivatives See Note 1 of the Notes to the Consolidated Financial Statements included in the 2022 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 8 of the Notes to the Consolidated Financial Statements included in the 2022 Annual Report.

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 September 30, 2023 December 31, 2022 September 30, 2023 December 31, 2022 (In millions) Fixed maturity securities AFS $ 110 $ 247 $ 1 $ 1 Mortgage loans $ 304 $ 319 $ (15) $ (18) Future policy benefits $ (2,579) $ (2,816) $ 431 $ 200 Policyholder account balances $ (1,696) $ (1,735) $ 119 $ 80 __________________ (1) Includes ($119) million and ($136) million of hedging adjustments on discontinued hedging relationships at September 30, 2023 and December 31, 2022, 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 $1 million and $21 million for the three months and nine months ended September 30, 2023, respectively, and $18 million and $22 million for the three months and nine months ended September 30, 2022, respectively. At both September 30, 2023 and December 31, 2022, 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 six years. At September 30, 2023 and December 31, 2022, the balance in AOCI associated with cash flow hedges was $1.2 billion and $2.0 billion, respectively. All components of each derivative’s gain or loss were included in the assessment of hedge effectiveness. At September 30, 2023, the Company expected to reclassify $114 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: September 30, 2023 December 31, 2022 Rating Agency Designation of Referenced Estimated Maximum Weighted Estimated Maximum Weighted (Dollars in millions) Aaa/Aa/A Single name credit default swaps (3) $ — $ 10 0.7 $ 1 $ 10 1.5 Credit default swaps referencing indices 72 4,351 2.6 79 4,251 3.4 Subtotal 72 4,361 2.6 80 4,261 3.4 Baa Single name credit default swaps (3) — 55 2.5 — 40 2.5 Credit default swaps referencing indices 50 5,982 5.8 13 4,598 5.9 Subtotal 50 6,037 5.8 13 4,638 5.8 Ba Single name credit default swaps (3) 1 20 0.2 1 45 0.7 Credit default swaps referencing indices 2 25 3.2 2 25 4.0 Subtotal 3 45 1.9 3 70 1.9 B Credit default swaps referencing indices 1 75 5.2 1 75 4.5 Subtotal 1 75 5.2 1 75 4.5 Caa Credit default swaps referencing indices (7) 30 2.7 (10) 30 3.5 Subtotal (7) 30 2.7 (10) 30 3.5 Total $ 119 $ 10,548 4.4 $ 87 $ 9,074 4.6 __________________ (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 and Fitch Ratings. If no rating is available from a rating agency, then an internally developed rating is used. (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 over-the-counter bilateral (“OTC-bilateral”), contracts between two counterparties, 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: September 30, 2023 December 31, 2022 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) $ 7,279 $ 3,522 $ 8,456 $ 3,499 OTC-cleared (1) 71 12 57 29 Exchange-traded 2 — 2 1 Total gross estimated fair value of derivatives presented on the interim condensed consolidated balance sheets (1) 7,352 3,534 8,515 3,529 Gross amounts not offset on the interim condensed consolidated balance sheets: Gross estimated fair value of derivatives: (2) OTC-bilateral (2,983) (2,983) (3,317) (3,317) OTC-cleared (8) (8) (14) (14) Exchange-traded — — — — Cash collateral: (3), (4) OTC-bilateral (3,204) — (4,044) — OTC-cleared (52) — (18) (1) Securities collateral: (5) OTC-bilateral (1,026) (538) (1,078) (182) OTC-cleared — (4) — (14) Exchange-traded — — — (1) Net amount after application of master netting agreements and collateral $ 79 $ 1 $ 44 $ — __________________ (1) At September 30, 2023 and December 31, 2022, derivative assets included income (expense) accruals reported in accrued investment income or in other liabilities of $173 million and $119 million, respectively, and derivative liabilities included (income) expense accruals reported in accrued investment income or in other liabilities of $43 million and $0, 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 application of netting agreements. At September 30, 2023 and December 31, 2022, the Company received excess cash collateral of $182 million and $210 million, respectively, and provided excess cash collateral of $5 million and $1 million, respectively. (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 September 30, 2023, 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 September 30, 2023 and December 31, 2022, the Company received excess securities collateral with an estimated fair value of $315 million and $366 million, respectively, for its OTC-bilateral derivatives, which are not included in the table above due to the foregoing limitation. At September 30, 2023 and December 31, 2022, the Company provided excess securities collateral with an estimated fair value of $853 million and $934 million, respectively, for its OTC-bilateral derivatives, $453 million and $442 million, respectively, for its OTC-cleared derivatives, and $51 million and $96 million, respectively, for its exchange-traded derivatives, which are not included in the table above due to the 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 and 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.

(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. At September 30, 2023 and December 31, 2022, the estimated fair value of such investments was $55 million and $61 million, respectively. (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.

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, in addition to those described above for fixed maturities AFS. Other investments also include certain real estate joint ventures 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 guarantees related to reinsurance is determined based on multiple stochastic scenarios and includes a nonperformance risk adjustment. 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. Market Risk Benefits 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: September 30, 2023 December 31, 2022 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) 13 - 120 89 — - 126 89 Increase • Market pricing • Quoted prices (4) 4 - 102 91 20 - 107 92 Increase RMBS • Market pricing • Quoted prices (4) — - 112 93 — - 106 93 Increase (5) ABS & CLO • Market pricing • Quoted prices (4) 75 - 100 92 74 - 101 91 Increase (5) Derivatives Interest rate • Present value techniques • Swap yield (6) 433 - 462 451 372 - 392 381 Increase (7) Credit • Present value techniques • Credit spreads (8) — - — — 84 - 138 101 Decrease (7) • Consensus pricing • Offered quotes (9) Market Risk Benefits Direct and assumed guaranteed minimum benefits • Option pricing techniques • Mortality rates: Ages 0 - 40 0.01% - 0.13% 0.05% 0.01% - 0.08% 0.05% (10) Ages 41 - 60 0.05% - 0.67% 0.22% 0.05% - 0.43% 0.20% (10) Ages 61 - 115 0.35% - 100% 1.23% 0.34% - 100% 1.44% (10) • Lapse rates: Durations 1 - 10 0.80% - 20.10% 8.72% 0.50% - 37.50% 8.96% Decrease (11) Durations 11 - 20 3.10% - 10.10% 4.34% 0.70% - 35.75% 6.52% Decrease (11) Durations 21 - 116 0.10% - 10.10% 4.59% 1.60% - 35.75% 2.89% Decrease (11) • Utilization rates 0.20% - 22% 0.44% 0.20% - 22% 0.38% Increase (12) • Withdrawal rates 0.25% - 7.75% 4.47% 0.25% - 10% 4.02% (13) • Long-term equity volatilities 16.37% - 21.85% 18.55% 16.46% - 22.01% 18.49% Increase (14) • Nonperformance risk spread 0.41% - 0.77% 0.73% 0.34% - 0.74% 0.75% Decrease (15) __________________ (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) Represents the risk quoted in basis points of a credit default event on the underlying instrument. Credit derivatives with significant unobservable inputs are primarily comprised of written credit default swaps. (9) At September 30, 2023 and December 31, 2022, independent non-binding broker quotations were used in the determination of 3% and 1%, respectively, of the total net derivative estimated fair value. (10) 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. (11) 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. (12) 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. (13) 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 MRB. 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. (14) 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. (15) 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.” 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 September 30, 2023 Balance, beginning of period $ 16,016 $ 3,409 $ 4 $ 17 $ 17 Total realized/unrealized gains (losses) included in net income (loss) (1), (2) — (4) — 4 — Total realized/unrealized gains (losses) included in AOCI (529) (3) — (9) 1 Purchases (3) 652 320 — — 3 Sales (3) (456) (308) — — (8) Issuances (3) — — — — — Settlements (3) — — — — — Transfers into Level 3 (4) 115 48 — — — Transfers out of Level 3 (4) (189) (99) (4) (2) — Balance, end of period $ 15,609 $ 3,363 $ — $ 10 $ 13 Three Months Ended September 30, 2022 Balance, beginning of period $ 13,004 $ 4,090 $ — $ 21 $ 100 Total realized/unrealized gains (losses) included in net income (loss) (1), (2) (4) 10 — 4 — Total realized/unrealized gains (losses) included in AOCI (1,179) (110) — — — Purchases (3) 622 216 — — 5 Sales (3) (293) (181) — — — Issuances (3) — — — — — Settlements (3) — — — — — Transfers into Level 3 (4) 186 30 — — — Transfers out of Level 3 (4) (487) (94) — — (100) Balance, end of period $ 11,849 $ 3,961 $ — $ 25 $ 5 Changes in unrealized gains (losses) included in net income (loss) for the instruments still held at September 30, 2023 (5) $ — $ (2) $ — $ 4 $ — Changes in unrealized gains (losses) included in net income (loss) for the instruments still held at September 30, 2022 (5) $ (3) $ 5 $ — $ 5 $ — Changes in unrealized gains (losses) included in AOCI for the instruments still held at September 30, 2023 (5) $ (538) $ (7) $ — $ (9) $ — Changes in unrealized gains (losses) included in AOCI for the instruments still held at September 30, 2022 (5) $ (1,180) $ (105) $ — $ — $ — Fair Value Measurements Using Significant Unobservable Inputs (Level 3) Residential Other Investments Net Net Embedded Separate (In millions) Three Months Ended September 30, 2023 Balance, beginning of period $ — $ 1,115 $ (278) $ 378 $ 1,054 Total realized/unrealized gains (losses) included in net income (loss) (1), (2) — (18) — 525 (12) Total realized/unrealized gains (losses) included in AOCI — — (107) — — Purchases (3) — 22 — — 15 Sales (3) — (2) — — (30) Issuances (3) — — — — — Settlements (3) — — 91 (26) — Transfers into Level 3 (4) — — — — 6 Transfers out of Level 3 (4) — — — — (10) Balance, end of period $ — $ 1,117 $ (294) $ 877 $ 1,023 Three Months Ended September 30, 2022 Balance, beginning of period $ 109 $ 961 $ (103) $ (81) $ 1,029 Total realized/unrealized gains (losses) included in net income (loss) (1), (2) 1 (20) (176) 488 2 Total realized/unrealized gains (losses) included in AOCI — — (124) — — Purchases (3) — 4 54 — 61 Sales (3) (108) (9) — — (75) Issuances (3) — — (1) — (1) Settlements (3) (2) — 25 41 — Transfers into Level 3 (4) — — — — — Transfers out of Level 3 (4) — — (161) — (11) Balance, end of period $ — $ 936 $ (486) $ 448 $ 1,005 Changes in unrealized gains (losses) included in net income (loss) for the instruments still held at September 30, 2023 (5) $ — $ (18) $ — $ 525 $ — Changes in unrealized gains (losses) included in net income (loss) for the instruments still held at September 30, 2022 (5) $ — $ (21) $ (31) $ 488 $ — Changes in unrealized gains (losses) included in AOCI for the instruments still held at September 30, 2023 (5) $ — $ — $ (92) $ — $ — Changes in unrealized gains (losses) included in AOCI for the instruments still held at September 30, 2022 (5) $ — $ — $ (145) $ — $ — Fair Value Measurements Using Significant Unobservable Inputs (Level 3) Fixed Maturity Securities AFS Corporate (6) Structured Municipals Foreign Short-term (In millions) Nine Months Ended September 30, 2023 Balance, beginning of period $ 14,733 $ 3,373 $ — $ 15 $ 47 Total realized/unrealized gains (losses) included in net income (loss) (1), (2) (25) (3) — 3 — Total realized/unrealized gains (losses)

Commitments and Contingencies Disclosure [Abstract]
Contingencies, Commitments and Guarantees	16. 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 September 30, 2023. 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 September 30, 2023, 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 2022 Annual Report, Metropolitan Life Insurance Company received approximately 2,610 asbestos-related claims in 2022. For the nine months ended September 30, 2023 and 2022, Metropolitan Life Insurance Company received approximately 1,924 and 1,962 new asbestos-related claims, respectively. See Note 16 of the Notes to the Consolidated Financial Statements included in the 2022 Annual Report for historical information concerning asbestos claims and Metropolitan Life Insurance Company’s update in its recorded liability at December 31, 2022. 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 September 30, 2023. 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 this 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 $2.0 billion and $2.7 billion at September 30, 2023 and December 31, 2022, 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 $4.8 billion at September 30, 2023 and December 31, 2022, 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 $220 million, with a cumulative maximum of $317 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. Except for balances affected by the adoption of Accounting Standards Update (“ASU”) 2018-12 noted below, the December 31, 2022 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, 2022 (the “2022 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 2022 Annual Report. Adoption of ASU 2018-12 - Targeted Improvements to the Accounting for Long-Duration Contracts Effective January 1, 2023, the Company adopted ASU 2018-12, Financial Services—Insurance (Topic 944): Targeted Improvements to the Accounting for Long-Duration Contracts , as amended by ASU 2019-09, Financial Services—Insurance (Topic 944): Effective Date ; ASU 2020-11, Financial Services—Insurance (Topic 944): Effective Date and Early Application ; and ASU 2022-05, Financial Services—Insurance (Topic 944): Transition for Sold Contracts (“LDTI”), with a transition date of January 1, 2021 (the “Transition Date”). Adoption of LDTI impacted the Company’s accounting and presentation related to long-duration insurance contracts and certain related balances for the years ended December 31, 2022 and 2021. Amounts within these interim condensed consolidated financial statements which were previously presented, have been revised to conform with the current year accounting and presentation under LDTI. Disclosures as of the Transition Date are reflected in summary within “— Recent Accounting Pronouncements — Adoption of ASU 2018-12 - Targeted Improvements to the Accounting for Long-Duration Contracts,” and in further detail (at the disaggregated level) within Notes 3, 4, 5 and 7. 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 or the fair value option (“FVO”) 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.
Reclassifications	Revisions Cash flows from short term investments in the prior years’ Interim Condensed Consolidated Statement of Cash Flows, which were previously presented net, have been revised to gross presentation to conform with the current year presentation. The revision in presentation was not material to the previously presented financial statements.
Pending Transaction	Pending Reinsurance Transaction In May 2023, the Company entered into a definitive agreement with a subsidiary of Global Atlantic Financial Group, a retirement and life insurance company, to reinsure an in-force block of universal life, variable universal life, universal life with secondary guarantees, and fixed annuities, which are reported in the MetLife Holdings segment. At the closing of the transaction, the Company will enter into a reinsurance agreement on a coinsurance basis for the general account products, and on a modified coinsurance basis for the separate account products, representing total liabilities of approximately $12.8 billion at September 30, 2023. Under the terms of such agreement, assets primarily consisting of fixed maturity securities available-for-sale and mortgage loans supporting the general account liabilities will be transferred to the reinsurer at closing, reduced by an approximately $1.8 billion pre-tax ceding commission. The Company will retain separate account assets of approximately $4.7 billion at September 30, 2023 under the modified coinsurance arrangement. The transaction is expected to close in the fourth quarter of 2023 and is subject to satisfaction of certain remaining closing conditions. As of October 31, 2023, the Company had received all required regulatory approvals. See Note 9 for additional information on assets to be transferred to the reinsurer at closing, including associated impairments recorded to net investment gains (losses).
Future Policy Benefit Liabilities and Policyholder Account Balances	Future Policy Benefit Liabilities Traditional Non-participating and Limited-payment Long-duration products The Company establishes future policy benefit liabilities (“FPBs”) for amounts payable under traditional non-participating and limited-payment long-duration insurance and reinsurance policies which include, but are not limited to, pension risk transfers, structured settlements, institutional income annuities and long-term care products. Generally, amounts are payable over an extended period of time and the related liabilities are calculated as the present value of future expected benefits and claim settlement expenses to be paid, reduced by the present value of future expected net premiums. FPBs are measured as cohorts (e.g., groups of long-duration contracts), with the exception of pension risk transfers and longevity reinsurance solutions contracts, each of which are generally considered their own cohort. Contracts from different subsidiaries or branches, issue years, benefit currencies and product types are not grouped together in the same cohort. Such liabilities are established based on methods and underlying assumptions in accordance with GAAP and applicable actuarial standards. A net premium ratio (“NPR”) approach is utilized, where net premiums (i.e., the portion of gross premiums required to fund expected insurance benefits and claim settlement expenses) under the contract are accrued each period as an FPB. The NPR used to accrue the FPB in each period is determined by using the historical and present value of expected future benefits and claim settlement expenses for the cohort divided by the historical and present value of expected future gross premiums for the cohort. Cash flow assumptions are incorporated into the calculation of a cohort's NPR and FPB reserve. These assumptions are used to project the amount and timing of expected benefits and claim settlement expenses to be paid and the expected amount of premiums to be collected for a cohort. The principal inputs and assumptions used in the establishment of FPBs are actual premiums, actual benefits, in-force policies, and best estimate cash flow assumptions to project future premium and benefit amounts. The Company’s primary best estimate cash flow assumptions include expectations related to mortality, morbidity, termination, claim settlement expense, policy lapse, renewal, retirement, disability incidence, disability terminations, inflation and other contingent events as appropriate to the respective product type and geographical area. Upon transition to LDTI, generally, the NPR and FPB reserve are updated retrospectively on a quarterly basis for actual experience and at least once a year for any changes in future cash flow assumptions, except for claim settlement expenses, for which the Company has elected to lock in assumptions at the Transition Date or inception (for contracts sold after the Transition Date), as allowed by LDTI. The resulting remeasurement (gain) loss is recorded through net income and reflects the impact on the change in the NPR based on experience at end of the quarter applied to the cumulative premiums received from the inception of the cohort (or from the Transition Date for contracts issued prior to the Transition Date) to the beginning of the quarter. The total contractual profit pattern is recognized over the expected life of the cohort by retrospectively updating the NPR. If net premiums exceed gross premiums (i.e., expected benefits exceed expected gross premiums), the FPB is increased, and a corresponding adjustment is recognized immediately in net income. The change in FPB reflected in the statement of operations is calculated using a locked-in discount rate. For products issued prior to the Transition Date, a cohort level locked-in discount rate was developed that reflected the interest accretion rates that were locked in at inception of the underlying contracts (unless there was a historical premium deficiency event that resulted in updating the interest accretion rate prior to the Transition Date), or the acquisition date for contracts acquired through an assumed in-force reinsurance transaction or a business combination. For contracts issued subsequent to the Transition Date, the upper-medium grade discount rate used for interest accretion is locked in for the cohort and represents the original upper-medium grade discount rate at the issue date of the underlying contracts. The FPB for all cohorts is remeasured to a current upper-medium grade discount rate at each reporting date through other comprehensive income (loss) (“OCI”). The Company generally interprets the upper-medium grade discount rate to be a rate comparable to that of a U.S. corporate single A rate that reflects the duration characteristics of the liability. The upper-medium grade discount rate for the products that are included in the disaggregated rollforwards in Note 3 which are issued in the U.S. is determined by using observable market data, including published single A base curves. The last liquid point on the upper-medium grade discount curve grades to an ultimate forward rate, which is derived using assumptions of economic growth, inflation, and a long-term upper-medium grade spread. For limited-payment long-duration contracts, the collection of premiums does not represent the completion of the earnings process, therefore, any gross premiums received in excess of net premiums is deferred and amortized as a deferred profit liability (“DPL”). The DPL is presented within FPBs and is amortized in proportion to either the present value of expected benefit payments or insurance in-force of each cohort to ensure that profits are recognized over the life of the underlying policies in that cohort, regardless of when premiums are received. This amortization of the DPL is recorded through net income within policyholder benefits and claims. Consistent with the Company’s measurement of traditional long-duration products, management also recognizes a FPB reserve for limited-payment contracts that is representative of the difference between the present value of expected future benefit payments and the present value of expected future net premiums, subject to retrospective remeasurement through net income and OCI, as described above. The DPL is also subject to retrospective remeasurement through net income, however, it is not remeasured for changes in discount rates. Traditional Participating Products The Company establishes FPBs for traditional participating contracts in the U.S., which include whole and term life participating contracts in both the open and closed block using a net premium approach, similar to traditional non-participating contracts. However, for participating contracts, the discount rate and actuarial assumptions are locked in at inception, include a provision for adverse deviation, and all changes in the associated FPBs are reported within policyholder benefits and claims. See Note 8 for additional information on the closed block. For traditional participating contracts, the Company reviews its estimates of actuarial liabilities for future benefits and compares them with current best estimate assumptions. The Company revises estimates, to increase FPBs, if the Company determines that the liabilities previously established for future benefit payments less future expected net premiums in the aggregate for this line of business prove inadequate. Additional Insurance Liabilities Liabilities for universal, variable universal, and variable life policies with secondary guarantees (“ULSG”) and paid-up guarantees are determined by estimating the expected value of death benefits payable when the account balance is projected to be zero and recognizing those benefits ratably over the life of the contract based on total expected assessments. The additional insurance liabilities are updated retrospectively on a quarterly basis for actual experience and at least once a year for any changes in future cash flow assumptions. The assumptions used in estimating the secondary and paid-up guarantee liabilities are investment income, mortality, lapse, and premium payment pattern and persistency. The assumptions of investment performance and volatility for variable products are consistent with historical experience of appropriate underlying equity indices, such as the S&P Global Ratings (“S&P”) 500 Index. The benefits used in calculating the liabilities are based on the average benefits payable over a range of scenarios. The resulting remeasurement (gain) loss recorded through net income reflects the impact on the change in the ratio of benefits payable to total assessments over the life of the contract based on experience at end of the quarter applied to the cumulative assessments received as of the beginning of the quarter. Premium Deficiency Reserves on Short-Duration Contracts Premium deficiency reserves may be established for short-duration contracts to provide for expected future losses and certain expenses that exceed unearned premiums. These reserves are based on actuarial estimates of the amount of loss inherent in that period, including losses incurred for which claims have not been reported. The provisions for unreported claims are calculated using studies that measure the historical length of time between the incurred date of a claim and its eventual reporting to the Company. Anticipated investment income is considered in the calculation of premium deficiency losses for short-duration contracts. Policyholder Account Balances Policyholder account balances (“PABs”) represent the amount held by the Company on behalf of the policyholder at each reporting date. This amount includes deposits received from the policyholder, interest credited to the policyholder’s account balance, net of charges assessed against the account balance and any policyholder withdrawals. This balance also includes liabilities for structured settlement and institutional income annuities, and certain other contracts, that do not contain significant insurance risk, as well as the estimated fair value of embedded derivatives associated with indexed annuity products.
Market Risk Benefit	Market Risk Benefits As defined by LDTI, market risk benefits (“MRBs”) are contracts or contract features that guarantee benefits, such as guaranteed minimum benefits, in addition to an account balance, which expose insurance companies to other than nominal capital market risk (equity price, interest rate, and/or foreign currency exchange risk) and subsequently protect the contractholder from the same risk. These contracts and contract features were generally recorded as embedded derivatives or additional insurance liabilities prior to the Transition Date. Certain contracts may have multiple contract features or guarantees. In these cases, each feature is separately evaluated to determine whether it meets the definition of an MRB at contract inception. If a contract includes multiple benefits that meet the definition of an MRB, those benefits are aggregated and measured as a single compound MRB. All identified MRBs are required to be measured at estimated fair value, whether the contract or contract feature represents a direct, assumed or ceded capital market risk. All MRBs in an asset position are aggregated and presented as an asset, and all MRBs in a liability position are aggregated and presented as a liability. Changes in the estimated fair value of MRBs are recognized in net income, except for the portion of the fair value change attributable to the change in nonperformance risk of the Company which is recorded as a separate component of OCI. The Company generally uses an attributed fee approach to value MRBs, where the attributed fee is determined at contract inception by estimating the fair value of expected future benefits and the expected future fees. The attributed fee percentage is the portion of the expected future fees due from contractholders deemed necessary at contract inception to fund all future expected benefits. This typically results in a zero fair value for the MRB at inception. The estimated fair value of the expected future benefits is estimated using a stochastically-generated set of risk-neutral scenarios. Once calculated, the attributed fee percentage is fixed and does not change over the life of the contract. All fees due from contractholders in excess of the attributed fees are reported in universal life and investment-type product policy fees.
Other Policy-Related Balances	Other Policy-Related Balances Other policy-related balances include policy and contract claims, premiums received in advance, unearned revenue (“UREV”) liabilities, obligations assumed under structured settlement assignments, policyholder dividends due and unpaid and policyholder dividends left on deposit. The liability for policy and contract claims generally relates to incurred but not reported (“IBNR”) death and dental claims. In addition, generally included in other policy-related balances are claims which have been reported but not yet settled for death and dental . The liability for these claims is based on the Company’s estimated ultimate cost of settling all claims. The Company derives estimates for the development of IBNR claims principally from analyses of historical patterns of claims by business line. The methods used to determine these estimates are continually reviewed. Adjustments resulting from this continuous review process and differences between estimates and payments for claims are recognized in policyholder benefits and claims expense in the period in which the estimates are changed or payments are made. The Company accounts for the prepayment of premiums on its individual life, group life and health contracts as premiums received in advance. These amounts are then recognized in premiums when due. The UREV liability relates to universal life and investment-type products and represents policy charges for services to be provided in future periods. The charges are deferred as unearned revenue and amortized on a basis consistent with the methodologies and assumptions used for amortizing deferred policy acquisition costs (“DAC”) for the related contracts. Changes in the UREV liability for each period (representing deferrals less amortization) are reported in universal life and investment-type product policy fees.
Recognition of Insurance Revenues and Deposits	Recognition of Insurance Revenues and Deposits Premiums related to whole and term life products, individual disability, individual and group fixed annuities (including pension risk transfers, certain structured settlements and certain income annuities), long-term care and participating products are recognized as revenues when due from policyholders. Policyholder benefits and expenses are provided to recognize profits over the estimated lives of the insurance policies. When premiums are due over a significantly shorter period than the period over which benefits are provided, any excess profit is deferred as a DPL and recognized into earnings in a constant relationship to insurance in-force or, for annuities, the present value of expected future policy benefit payments. Premiums related to short-duration non-medical health and disability contracts are recognized on a pro rata basis over the applicable contract term. Unearned premiums, representing the portion of premium written related to the unexpired coverage, are reflected as liabilities until earned. Deposits related to universal life and investment-type products are credited to PABs. Revenues from such contracts consist of fees for mortality, policy administration and surrender charges and are recorded in universal life and investment-type product policy fees in the period in which services are provided. All fees due from contractholders in excess of the attributed fees on contracts with MRBs are reported in universal life and investment-type product policy fees. Amounts that are charged to earnings include interest credited and benefit claims incurred in excess of related PABs. All revenues and expenses are presented net of reinsurance, as applicable.
Deferred Policy Acquisition Costs and Value of Business Acquired	Deferred Policy Acquisition Costs, Value of Business Acquired and Other Intangibles The Company incurs significant costs in connection with acquiring new and renewal insurance business. Costs that are related directly to the successful acquisition or renewal of insurance contracts are capitalized as DAC. Such costs include: • incremental direct costs of contract acquisition, such as commissions; • the portion of an employee’s total compensation and benefits related to time spent selling, underwriting or processing the issuance of new and renewal insurance business only with respect to actual policies acquired or renewed; and • other essential direct costs that would not have been incurred had a policy not been acquired or renewed. All other acquisition-related costs, including those related to general advertising and solicitation, market research, agent training, product development, unsuccessful sales and underwriting efforts, as well as all indirect costs, are expensed as incurred. Value of business acquired (“VOBA”) is an intangible asset resulting from a business combination that represents the excess of book value over the estimated fair value of acquired insurance, annuity, and investment-type contracts in-force at the acquisition date. The estimated fair value of the acquired liabilities is based on projections, by each block of business, of future policy and contract charges, premiums, mortality and morbidity, separate account performance, surrenders, operating expenses, investment returns, nonperformance risk adjustment and other factors. Actual experience with the purchased business may vary from these projections. VOBA is subject to periodic recoverability testing for traditional life and limited-payment contracts, as well as universal life type contracts. Beginning on the Transition Date, DAC and VOBA for most long-duration products are amortized on a constant-level basis that approximates straight-line amortization on an individual contract basis. The DAC and VOBA related to U.S. annuities are amortized over expected benefit payments, and for all other long-duration products are generally amortized in proportion to policy count. For short-duration products, DAC and VOBA are amortized in proportion to actual and expected future earned premiums.
Intangible Assets Arising from Insurance Contracts Acquired in Business Combination, Policy	Deferred Policy Acquisition Costs, Value of Business Acquired and Other Intangibles The Company incurs significant costs in connection with acquiring new and renewal insurance business. Costs that are related directly to the successful acquisition or renewal of insurance contracts are capitalized as DAC. Such costs include: • incremental direct costs of contract acquisition, such as commissions; • the portion of an employee’s total compensation and benefits related to time spent selling, underwriting or processing the issuance of new and renewal insurance business only with respect to actual policies acquired or renewed; and • other essential direct costs that would not have been incurred had a policy not been acquired or renewed. All other acquisition-related costs, including those related to general advertising and solicitation, market research, agent training, product development, unsuccessful sales and underwriting efforts, as well as all indirect costs, are expensed as incurred. Value of business acquired (“VOBA”) is an intangible asset resulting from a business combination that represents the excess of book value over the estimated fair value of acquired insurance, annuity, and investment-type contracts in-force at the acquisition date. The estimated fair value of the acquired liabilities is based on projections, by each block of business, of future policy and contract charges, premiums, mortality and morbidity, separate account performance, surrenders, operating expenses, investment returns, nonperformance risk adjustment and other factors. Actual experience with the purchased business may vary from these projections. VOBA is subject to periodic recoverability testing for traditional life and limited-payment contracts, as well as universal life type contracts. Beginning on the Transition Date, DAC and VOBA for most long-duration products are amortized on a constant-level basis that approximates straight-line amortization on an individual contract basis. The DAC and VOBA related to U.S. annuities are amortized over expected benefit payments, and for all other long-duration products are generally amortized in proportion to policy count. For short-duration products, DAC and VOBA are amortized in proportion to actual and expected future earned premiums.
Deferred Sales Inducements	The Company generally has two different types of sales inducements which are included in other assets: (i) the policyholder receives a bonus whereby the policyholder’s initial account balance is increased by an amount equal to a specified percentage of the customer’s deposit; and (ii) the policyholder receives a higher interest rate using a dollar cost averaging method than would have been received based on the normal general account interest rate credited. The Company defers sales inducements and amortizes them over the life of the policy using the same methodologies and assumptions used to amortize DAC for the related contracts. The amortization of sales inducements is included in policyholder benefits and claims. Each year, or more frequently if circumstances indicate a potential recoverability issue exists, the Company reviews deferred sales inducements (“DSI”) to determine the recoverability of the asset. DSI assets were $46 million and $49 million at September 30, 2023 and December 31, 2022, respectively.
Value of Distribution Agreements and Customer Relationships Acquired	Value of distribution agreements acquired (“VODA”) is reported in other assets and represents the present value of expected future profits associated with the expected future business derived from the distribution agreements acquired as part of a business combination. Value of customer relationships acquired (“VOCRA”) is also reported in other assets and represents the present value of the expected future profits associated with the expected future business acquired through existing customers of the acquired company or business. The VODA and VOCRA associated with past business combinations are amortized over the assets’ useful lives ranging from 10 to 30 years and such amortization is included in other expenses. Each year, or more frequently if circumstances indicate a possible impairment exists, the Company reviews VODA and VOCRA to determine whether the asset is impaired.
Reinsurance	Reinsurance For each of its reinsurance agreements, the Company determines whether the agreement provides indemnification against loss or liability relating to insurance risk in accordance with applicable accounting standards. Cessions under reinsurance agreements do not discharge the Company’s obligations as the primary insurer. The Company reviews all contractual features, including those that may limit the amount of insurance risk to which the reinsurer is subject or features that delay the timely reimbursement of claims. The reinsurance recoverable for traditional non-participating and limited-payment contracts is generally measured using a net premium methodology to accrue the projected net gain or loss on reinsurance in proportion to the gross premiums of the underlying reinsured cohorts; and is updated retrospectively on a quarterly basis for actual experience and at least once a year for any changes in cash flow assumptions. The locked-in discount rate used to measure changes in the reinsurance recoverable recorded in net income was established at the Transition Date, or at the inception of the reinsurance coverage for new reinsurance agreements entered into subsequent to the Transition Date. The reinsurance recoverable is remeasured to an upper-medium grade discount rate through OCI at each reporting date, similar to the underlying reinsured contracts. The reinsurance recoverable for other long-duration contracts and associated contract features is measured using assumptions and methods generally consistent with the underlying direct policies. For reinsurance of existing in-force blocks of long-duration contracts that transfer significant insurance risk, the difference, if any, between the amounts paid (received), and the liabilities ceded (assumed) related to the underlying reinsured contracts is considered the net cost of reinsurance at the inception of the reinsurance agreement. The net cost of reinsurance is amortized on a basis consistent with the methodologies and assumptions used for amortizing DAC related to the underlying reinsured contracts. Subsequent amounts paid (received) on the reinsurance of in-force blocks, as well as amounts paid (received) related to new business, are recorded as ceded (assumed) premiums; and ceded (assumed) premiums, reinsurance and other receivables (future policy benefits) are established. For prospective reinsurance of short-duration contracts that meet the criteria for reinsurance accounting, amounts paid (received) are recorded as ceded (assumed) premiums and ceded (assumed) unearned premiums. Ceded (assumed) unearned premiums are reflected as a component of premiums, reinsurance and other receivables (future policy benefits). Such amounts are amortized through earned premiums over the remaining contract period in proportion to the amount of insurance protection provided. For retroactive reinsurance of short-duration contracts that meet the criteria for reinsurance accounting, amounts paid (received) in excess of the related insurance liabilities ceded (assumed) are recognized immediately as a loss and are reported in the appropriate line item within the statement of operations. Any gain on such retroactive agreement is deferred and is amortized as part of DAC, primarily using the recovery method. Amounts currently recoverable under reinsurance agreements are included in premiums, reinsurance and other receivables and amounts currently payable are included in other liabilities. Assets and liabilities relating to reinsurance agreements with the same reinsurer may be recorded net on the balance sheet, if a right of offset exists within the reinsurance agreement. In the event that reinsurers do not meet their obligations to the Company under the terms of the reinsurance agreements, or when events or changes in circumstances indicate that its carrying amount may not be recoverable, reinsurance recoverable balances could become uncollectible. In such instances, reinsurance recoverable balances are stated net of allowances for uncollectible reinsurance, consistent with credit loss guidance which requires recording an allowance for credit loss (“ACL”). The funds withheld liability represents amounts withheld by the Company in accordance with the terms of the reinsurance agreements. The Company withholds the funds rather than transferring the underlying investments and, as a result, records funds withheld liability within other liabilities. The Company recognizes interest on funds withheld, included in other expenses, at rates defined by the terms of the agreement which may be contractually specified or directly related to the investment portfolio. See Note 1 of the Notes to the Consolidated Financial Statements included in the 2022 Annual Report for information on funds withheld assets. Premiums, fees and policyholder benefits and claims include amounts assumed under reinsurance agreements and are net of reinsurance ceded. Amounts received from reinsurers for policy administration are reported in other expenses.
Derivatives	Derivatives Freestanding Derivatives Freestanding derivatives are carried on the Company’s balance sheet either as assets within other invested assets or as liabilities within other liabilities at estimated fair value. The Company does not offset the estimated fair value amounts recognized for derivatives executed with the same counterparty under the same master netting agreement. Accruals on derivatives are generally recorded in accrued investment income or within other liabilities. However, accruals that are not scheduled to settle within one year are included with the derivative’s carrying value in other invested assets or other liabilities. If a derivative is not designated as an accounting hedge or its use in managing risk does not qualify for hedge accounting, changes in the estimated fair value of the derivative are reported in net derivative gains (losses) except as follows: Statement of Operations Presentation: Derivative: Net investment income • Economic hedges of equity method investments in joint ventures • Economic hedges of fair value option securities (“FVO Securities”) which are linked to equity indices Hedge Accounting To qualify for hedge accounting, at the inception of the hedging relationship, the Company formally documents its risk management objective and strategy for undertaking the hedging transaction, as well as its designation of the hedge. Hedge designation and financial statement presentation of changes in estimated fair value of the hedging derivatives are as follows: • Fair value hedge - a hedge of the estimated fair value of a recognized asset or liability - in the same line item as the earnings effect of the hedged item. The carrying value of the hedged recognized asset or liability is adjusted for changes in its estimated fair value due to the hedged risk. • Cash flow hedge - a hedge of a forecasted transaction or of the variability of cash flows to be received or paid related to a recognized asset or liability - in OCI and reclassified into the statement of operations when the Company’s earnings are affected by the variability in cash flows of the hedged item. The changes in estimated fair values of the hedging derivatives are exclusive of any accruals that are separately reported on the statement of operations within interest income or interest expense to match the location of the hedged item. In its hedge documentation, the Company sets forth how the hedging instrument is expected to hedge the designated risks related to the hedged item and sets forth the method that will be used to retrospectively and prospectively assess the hedging instrument’s effectiveness. A derivative designated as a hedging instrument must be assessed as being highly effective in offsetting the designated risk of the hedged item. Hedge effectiveness is formally assessed at inception and at least quarterly throughout the life of the designated hedging relationship. Assessments of hedge effectiveness are also subject to interpretation and estimation and different interpretations or estimates may have a material effect on the amount reported in net income. The Company discontinues hedge accounting prospectively when: (i) it is determined that the derivative is no longer highly effective in offsetting changes in the estimated fair value or cash flows of a hedged item; (ii) the derivative expires, is sold, terminated, or exercised; (iii) it is no longer probable that the hedged forecasted transaction will occur; or (iv) the derivative is de-designated as a hedging instrument. When hedge accounting is discontinued because it is determined that the derivative is not highly effective in offsetting changes in the estimated fair value or cash flows of a hedged item, the derivative continues to be carried on the balance sheet at its estimated fair value, with changes in estimated fair value recognized in net derivative gains (losses). The carrying value of the hedged recognized asset or liability under a fair value hedge is no longer adjusted for changes in its estimated fair value due to the hedged risk, and the cumulative adjustment to its carrying value is amortized into income over the remaining life of the hedged item. The changes in estimated fair value of derivatives related to discontinued cash flow hedges remain in OCI unless it is probable that the hedged forecasted transaction will not occur. When hedge accounting is discontinued because it is no longer probable that the forecasted transactions will occur on the anticipated date or within two months of that date, the derivative continues to be carried on the balance sheet at its estimated fair value, with changes in estimated fair value recognized currently in net derivative gains (losses). Deferred gains and losses of a derivative recorded in OCI pursuant to the discontinued cash flow hedge of a forecasted transaction that is no longer probable of occurring are recognized immediately in net investment gains (losses). In all other situations in which hedge accounting is discontinued, the derivative is carried at its estimated fair value on the balance sheet, with changes in its estimated fair value recognized in the current period as net derivative gains (losses). Embedded Derivatives As discussed above, certain guarantees previously accounted for as embedded derivatives are accounted for as MRBs upon adoption of LDTI. The Company issues certain products and investment contracts and is a party to certain reinsurance agreements that have embedded derivatives. The Company assesses each identified embedded derivative to determine whether it is required to be bifurcated. The embedded derivative is bifurcated from the host contract and accounted for as a freestanding derivative if: • the contract or contract feature does not meet the definition of a MRB (as a result of the adoption of LDTI); • the combined instrument is not accounted for in its entirety at estimated fair value with changes in estimated fair value recorded in earnings; • the terms of the embedded derivative are not clearly and closely related to the economic characteristics of the host contract; and • a separate instrument with the same terms as the embedded derivative would qualify as a derivative instrument. Such embedded derivatives are carried on the balance sheet at estimated fair value with the host contract and changes in their estimated fair value are generally reported in net derivative gains (losses). If the Company is unable to properly identify and measure an embedded derivative for separation from its host contract, the entire contract is carried on the balance sheet at estimated fair value, with changes in estimated fair value recognized in the current period in net investment gains (losses) or net investment income. Additionally, the Company may elect to carry an entire contract on the balance sheet at estimated fair value, with changes in estimated fair value recognized in the current period in net investment gains (losses) or net investment income if that contract contains an embedded derivative that requires bifurcation. 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 over-the-counter bilateral (“OTC-bilateral”), contracts between two counterparties, 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.
New Accounting Pronouncements	Recent Accounting Pronouncements Changes to GAAP are established by the Financial Accounting Standards Board (“FASB”) in the form of ASUs 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 interim condensed consolidated financial statements. Adoption of ASU 2018-12 - Targeted Improvements to the Accounting for Long-Duration Contracts The Company adopted LDTI effective January 1, 2023 with a Transition Date of January 1, 2021. The standard required a full retrospective transition approach for MRBs, and allowed for a transition method election for FPBs and DAC, as well as other balances that have historically been amortized in a manner consistent with DAC. The Company has elected the modified retrospective transition approach for all FPBs, DAC, and related balances on all long-duration contracts, subject to the transition provisions. Additionally, an amendment in LDTI allowed entities to make an accounting policy election to exclude certain sold or disposed contracts or legal entities from application of the transition guidance. The Company did not make such an election. Under the modified retrospective approach, the Company was required to establish LDTI-compliant FPBs, DAC and related balances for the Company’s Transition Date opening balance sheet by utilizing the Company’s December 31, 2020 balances with certain adjustments as described below. The following table presents a summary of the Transition Date impacts associated with the implementation of LDTI to the consolidated balance sheet: Premiums, Reinsurance and Other Receivables Deferred Policy Acquisition Costs and Value of Business Acquired Deferred Tax Asset Other Future Policy Benefits Policyholder Account Balances Market Risk Benefit Liabilities Deferred Income Tax Liability Retained Earnings Accumulated Other Comprehensive Income (Loss) (In millions) Balances as reported, December 31, 2020 $ 21,478 $ 2,649 $ — $ 4,158 $ 133,921 $ 96,635 $ — $ 1,980 $ 10,548 $ 11,662 Reclassification of carrying amounts of contracts and contract features that are market risk benefits (59) — — — (1,447) (495) 1,883 — — — Adjustments for the difference between previous carrying amounts and fair value measurements for market risk benefits — — — — — — 4,906 (1,030) (3,897) 21 Removal of related amounts in accumulated other comprehensive income — 1,482 — 29 (6,835) — — 1,751 — 6,595 Adjustment of future policy benefits to remeasure cohorts where net premiums exceed gross premiums under the modified retrospective approach 32 — — — 89 — — (12) (45) — Effect of remeasurement of future policy benefits to an upper-medium grade discount rate 403 — — — 25,208 — — (5,209) — (19,596) Adjustments for the cumulative effect of adoption on additional insurance assets and liabilities 29 — — — 36 — — — (7) Other balance sheet reclassifications and adjustments upon adoption of the LDTI standard 2 12 2,518 — (4,794) 4,794 — 2,520 10 — Balances as adjusted, January 1, 2021 $ 21,885 $ 4,143 $ 2,518 $ 4,187 $ 146,178 $ 100,934 $ 6,789 $ — $ 6,616 $ (1,325) The Transition Date impacts associated with the implementation of LDTI were applied as follows: Market Risk Benefits (See Note 5) The full retrospective transition approach for MRBs required assessing products to determine whether contract or contract features expose the Company to other than nominal capital market risk. The population of MRBs identified was then reviewed to determine the historical measurement model prior to adoption of LDTI. If the MRB was a bifurcated embedded derivative prior to the adoption of LDTI, the existing measurement approach was retained, except that the fair value of the MRB at inception was recalculated to isolate the contract issue date nonperformance risk of the Company. If, prior to the adoption of LDTI, the MRB was partially a bifurcated embedded derivative (e.g., a contract with multiple features where one was a bifurcated embedded derivative and one was an additional insurance liability), or was accounted for under a different model, the at-inception attributed fee ratio was calculated for every identified MRB, and using the at inception attributed fee ratio, the fair value of the MRB at the contract issue date was calculated to isolate the contract issue date nonperformance risk of the Company. At the Transition Date, the impacts to the financial statements of the full retrospective approach for MRBs include the following: • The amounts previously recorded for these contracts within additional insurance liabilities, embedded derivatives, and other insurance liabilities were reclassified to MRB liabilities; • The difference between the fair value of the MRBs and the previously recorded carrying value at the Transition Date, excluding the cumulative effect of changes in nonperformance risk of the Company, was recorded as an adjustment to the opening balance of retained earnings; and • The cumulative effect of changes in nonperformance risk between the contract issue date and the Transition Date was recorded as an adjustment to opening accumulated OCI (“AOCI”) as of the Transition Date. Future Policy Benefits (See Note 3) Traditional Non-participating Long-duration products • Loss recognition balances related to unrealized investment gains associated with certain long-duration products previously recorded in AOCI were removed; • Contracts in-force as of the Transition Date were grouped into cohorts; a revised NPR was calculated for each cohort using the existing Transition Date balance, best estimate cash flow assumptions without a provision for adverse deviation, and the historical discount rates used for the contracts within the cohort prior to the adoption of LDTI (the “locked-in” discount rate). For any cohorts where the net premiums exceeded gross premiums (NPR exceeded 100%), the FPB was increased for the excess of net premiums over gross premiums, with a corresponding adjustment recorded to opening retained earnings as of the Transition Date; • The difference between the FPB balance calculated at the current upper-medium grade discount rate and the FPB balance calculated at the locked-in discount rate was recorded as an adjustment to opening AOCI as of the Transition Date; and • Corresponding adjustments were made to ceded reinsurance balances. Limited-payment Long-duration products Limited-payment long-duration products transition to LDTI follows a similar approach to traditional non-participating products, except that these product cohorts may have a DPL which is adjusted at the Transition Date. If an increase to FPB depleted the DPL, the remaining adjustment was recorded to opening retained earnings as of the Transition Date. Additional insurance liabilities • The contracts and contract features that met the definition of a MRB were reclassified; • The impact of updating assessments used in the calculation of the additional insurance liabilities to reflect the constant margin amortization basis for UREV liabilities was recorded as an adjustment to opening retained earnings and AOCI; and • Corresponding adjustments were made to ceded reinsurance balances. DAC and other balances to be amortized in a manner consistent with DAC (VOBA, DSI and UREV) (See Note 7 for information on DAC, VOBA and UREV) The opening balances of these accounts were adjusted for removal of the related amounts in AOCI, as these balances are no longer amortized using expected future gross premiums, margins, profits or earned premiums. Other balance sheet reclassifications and adjustments at LDTI adoption (See Notes 3, 4 and 7) Individual income annuities reclassification Prior to the Transition Date, the Company classified all structured settlement and institutional income annuity products within FPBs. While the pre-LDTI GAAP reserving model was the same for these products, upon transition to LDTI, the reserving model for a subset of these products changed, requiring the Company to reclassify $4.7 billion of FPBs to PABs at the Transition Date. Other reclassifications and adjustments Other minor reclassifications and adjustments were made to conform to LDTI presentation requirements. The following table presents the effects of the retrospective application of the adoption of the new LDTI accounting guidance to the Company’s previously reported consolidated balance sheet: December

describes the impacts of the other ASUs adopted by the Company. Standard Description Effective Date and Impact on Financial Statements ASU 2022-02, Financial Instruments—Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures The amendments in the new ASU eliminate the accounting guidance for troubled debt restructurings by creditors that have adopted the current expected credit loss guidance while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty. In addition, the amendments require that a public business entity disclose current-period gross write-offs by year of origination for financing receivables and net investment in leases. January 1, 2023, the Company adopted, using a prospective approach. The adoption of the new guidance has reduced the complexity involved with evaluating and accounting for certain loan modifications. The Company has included the required disclosures within its interim condensed consolidated financial statements. ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting; as clarified and amended by ASU 2021-01, Reference Rate Reform (Topic 848): Scope; as amended by ASU 2022-06, Reference Rate Reform (Topic 848)—Deferral of the Sunset Date of Topic 848 The guidance provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships and other transactions affected by reference rate reform if certain criteria are met. The expedients and exceptions provided by the amendments do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, with certain exceptions. ASU 2021-01 amends the scope of the recent reference rate reform guidance. New optional expedients allow derivative instruments impacted by changes in the interest rate used for margining, discounting, or contract price alignment to qualify for certain optional relief. The amendments in ASU 2022-06 extend the sunset date of the reference rate reform optional expedients and exceptions to December 31, 2024. Effective for contract modifications made between March 12, 2020 and December 31, 2024. The guidance has reduced the operational and financial impacts of contract modifications that replace a reference rate, such as London Interbank Offered Rate, affected by reference rate reform. Contract modifications to replace reference rates affected by the reform occurred during 2021, 2022 and 2023. The adoption of the guidance did not have a material impact on the Company’s interim condensed 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. Assets have been allocated to the closed block in an amount that has been determined to produce cash flows which, together with anticipated revenues from the policies included in the closed block, are reasonably expected to be sufficient to support obligations and liabilities relating to these policies, including, but not limited to, provisions for the payment of claims and certain expenses and taxes, and to provide for the continuation of policyholder dividend scales in effect for 1999, if the experience underlying such dividend scales continues, and for appropriate adjustments in such scales if the experience changes. At least annually, the Company compares actual and projected experience against the experience assumed in the then-current dividend scales. Dividend scales are adjusted periodically to give effect to changes in experience. The closed block assets, the cash flows generated by the closed block assets and the anticipated revenues from the policies in the closed block will benefit only the holders of the policies in the closed block. To the extent that, over time, cash flows from the assets allocated to the closed block and claims and other experience related to the closed block are, in the aggregate, more or less favorable than what was assumed when the closed block was established, total dividends paid to closed block policyholders in the future may be greater than or less than the total dividends that would have been paid to these policyholders if the policyholder dividend scales in effect for 1999 had been continued. Any cash flows in excess of amounts assumed will be available for distribution over time to closed block policyholders and will not be available to stockholders. If the closed block has insufficient funds to make guaranteed policy benefit payments, such payments will be made from assets outside of the closed block. The closed block will continue in effect as long as any policy in the closed block remains in-force. The expected life of the closed block is over 100 years from the Demutualization Date. The Company uses the same accounting principles to account for the participating policies included in the closed block as it used prior to the Demutualization Date. However, the Company establishes a policyholder dividend obligation for earnings that will be paid to policyholders as additional dividends as described below. The excess of closed block liabilities over closed block assets at the Demutualization Date (adjusted to eliminate the impact of related amounts in AOCI) represents the estimated maximum future earnings from the closed block expected to result from operations, attributed net of income tax, to the closed block. Earnings of the closed block are recognized in income over the period the policies and contracts in the closed block remain in-force. If, over the period the closed block remains in existence, the actual cumulative earnings of the closed block are greater than the expected cumulative earnings of the closed block, the Company will pay the excess to closed block policyholders as additional policyholder dividends unless offset by future unfavorable experience of the closed block and, accordingly, will recognize only the expected cumulative earnings in income with the excess recorded as a policyholder dividend obligation. If over such period, the actual cumulative earnings of the closed block are less than the expected cumulative earnings of the closed block, the Company will recognize only the actual earnings in income. However, the Company may change policyholder dividend scales in the future, which would be intended to increase future actual earnings until the actual cumulative earnings equal the expected cumulative earnings. At least annually, management performs a premium deficiency test using best estimate assumptions to determine whether the projected future earnings of the closed block are sufficient to support the payment of future closed block contractual benefits. The most recent deficiency test demonstrated that the projected future earnings of the closed block are sufficient to support the payment of future closed block contractual benefits. 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 AFSActual 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 Management considers a wide range of factors about the security issuer and uses its best judgment in evaluating the cause of the decline in the estimated fair value of the security and in assessing the prospects for near-term recovery. Inherent in management’s evaluation of the security are assumptions and estimates about the operations of the issuer and its future earnings potential. Considerations used in the credit loss evaluation process include, but are not limited to: (i) the extent to which the estimated fair value has been below amortized cost, (ii) adverse conditions specifically related to a security, an industry sector or sub-sector, or an economically depressed geographic area, adverse change in the financial condition of the issuer of the security, changes in technology, discontinuance of a segment of the business that may affect future earnings, and changes in the quality of credit enhancement, (iii) payment structure of the security and likelihood of the issuer being able to make payments, (iv) failure of the issuer to make scheduled interest and principal payments, (v) whether the issuer, or series of issuers or an industry has suffered a catastrophic loss or has exhausted natural resources, (vi) whether the Company has the intent to sell or will more likely than not be required to sell, including transfers in connection with reinsurance transactions, a particular security before the decline in estimated fair value below amortized cost recovers, (vii) with respect to Structured Products, changes in forecasted cash flows after considering the changes in the financial condition of the underlying loan obligors and quality of underlying collateral, expected prepayment speeds, current and forecasted loss severity, consideration of the payment terms of the underlying assets backing a particular security, and the payment priority within the tranche structure of the security, (viii) changes in the rating of the security by a rating agency, and (ix) other subjective factors, including concentrations and information obtained from regulators. The methodology and significant inputs used to determine the amount of credit loss are as follows: • The Company calculates the recovery value by performing a discounted cash flow analysis based on the present value of future cash flows. The discount rate is generally the effective interest rate of the security at the time of purchase for fixed-rate securities and the spot rate at the date of evaluation of credit loss for floating-rate securities. • When determining collectability and the period over which value is expected to recover, the Company applies considerations utilized in its overall credit loss evaluation process which incorporates information regarding the specific security, fundamentals of the industry and geographic area in which the security issuer operates, and overall macroeconomic conditions. Projected future cash flows are estimated using assumptions derived from management’s single best estimate, the most likely outcome in a range of possible outcomes, after giving consideration to a variety of variables that include, but are not limited to: payment terms of the security; the likelihood that the issuer can service the interest and principal payments; the quality and amount of any credit enhancements; the security’s position within the capital structure of the issuer; possible corporate restructurings or asset sales by the issuer; any private and public sector programs to restructure foreign government securities and municipals; and changes to the rating of the security or the issuer by rating agencies. • Additional considerations are made when assessing the unique features that apply to certain Structured Products including, but not limited to: the quality of underlying collateral, historical performance of the underlying loan obligors, historical rent and vacancy levels, changes in the financial condition of the underlying loan obligors, expected prepayment speeds, current and forecasted loss severity, consideration of the payment terms of the underlying loans or assets backing a particular security, changes in the quality of credit enhancement and the payment priority within the tranche structure of the security. With respect to securities that have attributes of debt and equity (“perpetual hybrid securities”), consideration is given in the credit loss analysis as to whether there has been any deterioration in the credit of the issuer and the likelihood of recovery in value of the securities that are in a severe unrealized loss position. Consideration is also given as to whether any perpetual hybrid securities with an unrealized loss, regardless of credit rating, have deferred any dividend payments. In periods subsequent to the recognition of an initial ACL on a security, the Company reassesses credit loss quarterly. Subsequent increases or decreases in the expected cash flow from the security result in corresponding decreases or increases in the ACL which are recognized in earnings and reported within net investment gains (losses); however, the previously recorded ACL is not reduced to an amount below zero. Full or partial write-offs are deducted from the ACL in the period the security, or a portion thereof, is considered uncollectible. Recoveries of amounts previously written off are recorded to the ACL in the period received. When the Company has the intent-to-sell the security or it is more likely than not that the Company will be required to sell the security before recovery of its amortized cost, any ACL is written off and the amortized cost is written down to estimated fair value through a charge within net investment gains (losses), which becomes the new amortized cost of the security. Allowance for Credit Loss Methodology The Company records an allowance for expected lifetime credit loss in earnings within net investment gains (losses) in an amount that represents the portion of the amortized cost basis of mortgage loans that the Company does not expect to collect, resulting in mortgage loans being presented at the net amount expected to be collected. In determining the Company’s ACL, management applies significant judgment to estimate expected lifetime credit loss, including: (i) pooling mortgage loans that share similar risk characteristics, (ii) considering expected lifetime credit loss over the contractual term of its mortgage loans adjusted for expected prepayments and any extensions, and (iii) considering past events and current and forecasted economic conditions. Each of the Company’s commercial, agricultural and residential mortgage loan portfolio segments are evaluated separately. The ACL is calculated for each mortgage loan portfolio segment based on inputs unique to each loan portfolio segment. On a quarterly basis, mortgage loans within a portfolio segment that share similar risk characteristics, such as internal risk ratings or consumer credit scores, are pooled for calculation of ACL. On an ongoing basis, mortgage loans with dissimilar risk characteristics (i.e., loans with significant declines in credit quality), such as collateral dependent mortgage loans (i.e., when the borrower is experiencing financial difficulty, including when foreclosure is reasonably possible or probable), are evaluated individually for credit loss. The ACL for loans evaluated individually are established using the same methodologies for all three portfolio segments. For example, the ACL for a collateral dependent loan is established as the excess of amortized cost over the estimated fair value of the loan’s underlying collateral, less selling cost when foreclosure is probable. Accordingly, the change in the estimated fair value of collateral dependent loans, which are evaluated individually for credit loss, is recorded as a change in the ACL which is recorded on a quarterly basis as a charge or credit to earnings in net investment gains (losses). Mortgage loans to be disposed of in connection with a pending reinsurance transaction are carried at the lower of amortized cost or estimated fair value. 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. Commitments to lend: After 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 are 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 where the borrower was determined to be experiencing financial difficulties and the mortgage loans were modified by any of the following means, principal forgiveness, interest rate reduction, other-than-insignificant payment delay or term extension. The amount, timing and extent of modifications granted are considered in determining any ACL recorded. Commercial mortgage loans: For the three months ended September 30, 2023, the Company granted a short-term extension on a loan with an amortized cost of $135 million. In addition, the Company further extended the term of a loan modified in the first and second quarters of 2023 by an additional two months. These modifications added a weighted-average of less than one year to the life of the modified loans. These modified loans represent less than 1% of the portfolio segment. For the nine months ended September 30, 2023, the Company granted term extensions on loans with an amortized cost of $315 million. These modifications added a weighted-average of less than one year to the life of the modified loans. These modified loans represent less than 1% of the portfolio segment. Residential mortgage loans: For the three months ended September 30, 2023, the Company granted term extensions on loans with an amortized cost of $1 million, other-than-insignificant payment delays on loans with an amortized cost of $7 million, and term extensions and other-than-insignificant payment delays on loans with an amortized cost of $6 million. These modified loans represent less than 1% of the portfolio segment. These loan modifications added a weighted-average of eight years to the life of the modified loans. For the nine months ended September 30, 2023, the Company granted term extensions on loans with an amortized cost of $6 million, other-than-insignificant payment delays on loans with an amortized cost of $12 million, term extensions and other-than-insignificant payment delays on loans with an amortized cost of $15 million and term extensions, other-than-insignificant payment delays and interest rate reductions on loans with an amortized cost of $4 million. These modified loans represent less than 1% of the portfolio segment. These loan modifications added a weighted-average of nine years to the life of the modified loans, capitalized or deferred amounts due and reduced the weighted-average interest rate of the modified loans from 5.8% to 4.2%. For both the three months and nine months ended September 30, 2023, the Company did not have a significant amount of mortgage loans that were modified to borrowers experiencing financial difficulty that were not considered current.

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: September 30, 2023 December 31, 2022 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) 13 - 120 89 — - 126 89 Increase • Market pricing • Quoted prices (4) 4 - 102 91 20 - 107 92 Increase RMBS • Market pricing • Quoted prices (4) — - 112 93 — - 106 93 Increase (5) ABS & CLO • Market pricing • Quoted prices (4) 75 - 100 92 74 - 101 91 Increase (5) Derivatives Interest rate • Present value techniques • Swap yield (6) 433 - 462 451 372 - 392 381 Increase (7) Credit • Present value techniques • Credit spreads (8) — - — — 84 - 138 101 Decrease (7) • Consensus pricing • Offered quotes (9) Market Risk Benefits Direct and assumed guaranteed minimum benefits • Option pricing techniques • Mortality rates: Ages 0 - 40 0.01% - 0.13% 0.05% 0.01% - 0.08% 0.05% (10) Ages 41 - 60 0.05% - 0.67% 0.22% 0.05% - 0.43% 0.20% (10) Ages 61 - 115 0.35% - 100% 1.23% 0.34% - 100% 1.44% (10) • Lapse rates: Durations 1 - 10 0.80% - 20.10% 8.72% 0.50% - 37.50% 8.96% Decrease (11) Durations 11 - 20 3.10% - 10.10% 4.34% 0.70% - 35.75% 6.52% Decrease (11) Durations 21 - 116 0.10% - 10.10% 4.59% 1.60% - 35.75% 2.89% Decrease (11) • Utilization rates 0.20% - 22% 0.44% 0.20% - 22% 0.38% Increase (12) • Withdrawal rates 0.25% - 7.75% 4.47% 0.25% - 10% 4.02% (13) • Long-term equity volatilities 16.37% - 21.85% 18.55% 16.46% - 22.01% 18.49% Increase (14) • Nonperformance risk spread 0.41% - 0.77% 0.73% 0.34% - 0.74% 0.75% Decrease (15) __________________ (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) Represents the risk quoted in basis points of a credit default event on the underlying instrument. Credit derivatives with significant unobservable inputs are primarily comprised of written credit default swaps. (9) At September 30, 2023 and December 31, 2022, independent non-binding broker quotations were used in the determination of 3% and 1%, respectively, of the total net derivative estimated fair value. (10) 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. (11) 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. (12) 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. (13) 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 MRB. 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. (14) 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. (15) 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.
