Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Basis of Presentation	BUSINESS AND BASIS OF PRESENTATION Business Reinsurance Group of America, Incorporated (“RGA”) is an insurance holding company that was formed on December 31, 1992. RGA and its subsidiaries (collectively, the “Company”) is engaged in providing traditional reinsurance, which includes individual and group life and health, disability and critical illness reinsurance. The Company also provides financial solutions, which includes longevity reinsurance, asset-intensive products (primarily annuities), financial reinsurance, capital solutions and stable value products. Basis of Presentation The unaudited condensed consolidated financial statements of the Company have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X of the Securities and Exchange Commission (“SEC”). Accordingly, these condensed consolidated financial statements do not include all of the information and footnotes required by GAAP for complete financial statements and should be read in conjunction with the Company’s 2022 Annual Report on Form 10-K filed with the SEC on February 24, 2023 (the “2022 Annual Report”). In the opinion of management, all adjustments, including normal recurring adjustments necessary for a fair presentation have been included. Interim results are not necessarily indicative of the results that may be expected for the year ending December 31, 2023. Consolidation These unaudited condensed consolidated financial statements include the accounts of RGA and its subsidiaries and all intercompany accounts and transactions have been eliminated. Entities in which the Company has significant influence over the operating and financing decisions but are not required to be consolidated are reported under the equity method of accounting. Standards Issued and Implemented In the first quarter of 2023, the Company adopted Accounting Standards Update (“ASU”): ASU 2018-12, Financial Services – Insurance (Topic 944): Targeted Improvements to the Accounting for Long-Duration Contracts (“ASU 2018-12”). ASU 2018-12 updates certain requirements for the accounting for long-duration insurance contracts. • Cash flow assumptions and measuring liability for future policy benefits – ASU 2018-12 requires the Company to review its cash flow assumptions at least annually and update, if necessary, with the impact recognized in net income in the period of the change. The liability for future policy benefits includes required adjustments at the cohort level to cap the net premium ratio at 100% and eliminate negative reserves. Upon adoption, an adjustment was recorded to retained earnings as a result of capping the net premium ratio at 100% and eliminating negative reserves on certain issue year cohorts. • Discount rat e – The discount rate assumption is prescribed by ASU 2018-12 as an upper-medium (low credit risk) fixed-income yield and is required to be updated every quarter. The change in the liability as a result of updating the discount rate assumption is recognized in other comprehensive income (loss) (“OCI”). Upon adoption, an adjustment was recorded to accumulated other comprehensive income (loss) (“AOCI”) as a result of remeasuring in force contract liabilities using the current upper-medium grade fixed income instrument yields as of the date of transition. The adjustment reflects the difference between discount rates locked-in at contract inception versus current discount rates at transition. • Deferred policy acquisition costs and similar balances – Deferred policy acquisition costs (“DAC”) and other capitalized costs such as unearned revenue should be amortized on a constant level or straight-line basis over the expected term of the contracts. Upon adoption, an adjustment was recorded to AOCI for the removal of cumulative adjustments to DAC associated with unrealized investment gains and losses previously recorded in accumulated other comprehensive income (loss). • Market risk benefits – Market risk benefits, which are contracts or contract features that provide protection to the policyholder from capital market risk and expose the Company to other-than-nominal capital market risk, are measured at fair value. The periodic change in fair value is recognized in net income with the exception of the periodic change in fair value related to the liability’s instrument-specific credit risk, which is recognized in OCI. Upon adoption, an adjustment was recorded to retained earnings for the difference between the fair value and carrying value of the contracts at the transition date, excluding changes in the instrument-specific credit risks, and an adjustment to AOCI for the cumulative effect of changes in the instrument-specific credit risk between contract issue date and transition date. Change in Certain Segment Allocations Investment income for each segment has been adjusted to reflect the impacts of adopting ASU 2018-12 and due to an update to the Company’s internally developed economic capital model. Internal excess capital charges, included in each segment’s policy acquisition costs and other insurance expenses, were also updated as a result of adopting ASU 2018-12 and updates to the Company’s internally developed economic capital model. These changes did not impact the recognition or presentation of investment income or policy acquisition costs and other insurance expenses in the condensed consolidated financial statements. Significant Accounting Polices – Update The Company’s significant accounting policies are discussed in Note 2 – “ Significant Accounting Policies and Pronouncements” of the 2022 Annual Report. The significant accounting policies discussed below have been updated to reflect the impact of adopting ASU 2018-12. Liability for Future Policy Benefits Utilizing the net premium model, a liability for future policy benefits for life and long-term health business is established to meet the estimated future benefits to be paid on assumed life and health reinsurance in force less the present value of estimated future new premiums to be collected. The liability is estimated using the Company’s mortality, morbidity, and persistency assumptions that reflect the Company’s historical experience, industry data, cedant specific experience, and discount rates based on the current yields of upper-medium grade fixed income instruments. These assumptions vary with the characteristics of the reinsurance contract, the year the risk was assumed, age of the insured and other appropriate factors. The Company reviews actual and anticipated experience compared to the assumptions used to establish policy benefits on a quarterly basis and will update those assumptions if evidence suggests that they should be revised. The Company expects to complete its annual review and any necessary updates of cash flow assumptions used to calculate the liability for future policy benefits during the third quarter of each year. Updates may occur in other quarters if information becomes available during the quarter that indicates an assumption update is necessary. Liabilities for future benefits for annuities in the payout phase have been established in an amount adequate to meet the estimated future obligations on policies in force using expected mortality, discount rates and other assumptions. These assumptions vary with the characteristics of the plan of insurance, year of issue, age of insured, and other appropriate factors. The mortality assumptions are based on the Company’s historical experience, industry data and cedant specific experience. A deferred profit liability is established when the insurance benefit extends beyond the period in which premiums are collected, and the gross premium exceeds the net premium. The deferred profit liability is amortized in proportion to insurance in force for traditional life insurance and expected future benefits for annuity contracts. The deferred profit liability is included in the liabilities for future policy benefits, and the amortization of the deferred profit liability is recognized as a reduction in claims and other policy benefits. For the purpose of calculating the liability for future policy benefits, the Company’s reinsurance contracts for its Traditional business are grouped into annual cohorts based on the effective date of the reinsurance contract. The annual groupings are further disaggregated based on: • How the reinsurance contracts are priced and managed; • Geographical locations; • Underlying currency of the contract; • Ceding company and other factors. Given the unique risks and highly customized nature of the Company’s financial solutions business, reinsurance contracts for the Financial Solutions business are not aggregated with other contracts for the purpose of calculating the liability for future policy benefits. Each quarter, the Company updates its estimate of cash flows expected over the entire life of a group of contracts using actual historical experience and current future cash flow assumptions. These updated cash flows, discounted using the original contract issuance discount rates, are used to calculate the revised net premium ratio, as of the beginning of the current reporting period. The present value of these updated cash flows is compared to the carrying amount of the liability as of that same date, before updating cash flow assumptions, to determine the current period change in the liability’s estimate. This current period change in the liability is a component of the liability remeasurement gain or loss. In subsequent periods, the revised net premium ratio is used to measure the liability for future policy benefits, subject to future revisions. The Company also reviews actual and anticipated experience compared to the assumptions used to establish the liability for future policy benefits on a quarterly basis. If evidence suggests that the assumptions should be revised, the cumulative effect of the change is reflected in future policy benefits remeasurement (gains) losses in the current period. The Company has elected to lock-in claims expense assumptions at contract inception and those assumptions are not subsequently reviewed or updated. The discount rates used to measure the liability are based on upper-medium grade fixed-income instruments (A rated credit) with similar tenor to the expected liability cash flows. The discount rate assumption is updated quarterly and used to remeasure the liability at the reporting date, with the resulting change reflected in other comprehensive income (loss). For unobservable discount rates, the Company uses estimates consistent with fair value guidance, maximizing the use of relevant, observable market prices and minimizing the use of unobservable inputs. The Company utilizes the discount rate curve at contract inception for purposes of interest accretion and updating the net premium ratio. Interest accretion is recognized in claims and other policy benefits on the condensed consolidated statements of income. The locked-in discount curve at contract inception for contracts entered into after the adoption of ASU 2018-12 (i.e., January 1, 2021 and after) is based on the average upper-medium grade fixed-income instrument yields during the first calendar year of the reinsurance contract. The locked-in discount rates at contract inception for contracts that were effective prior to the adoption of ASU 2018-12 (i.e., prior to January 1, 2021) are the discount rate assumptions used prior to the adoption of ASU 2018-12, which were based on estimates of expected investment yields. Included in the liability for future policy benefits are unpaid claims related to long-duration contracts and an accrual for incurred but not reported losses (“IBNR”). The Company’s IBNR accrual related to long-duration contracts is determined using case-basis estimates and lag studies of past experience. The time lag from the date of the claim or death to when the ceding company reports the claim to the Company can vary significantly by ceding company, business segment and product type, but generally averages around 3 months. Incurred but not reported claims are estimates on an undiscounted basis, using actuarial estimates of historical claims expense, adjusted for current trends and conditions. These estimates are continually reviewed and the ultimate liability may vary significantly from the amount recognized. Claims payable for incurred but not reported losses for long-duration contracts are included in the liability for future policy benefits on the condensed consolidated balance sheets. Prior to the adoption of ASU 2018-12, unpaid claims and IBNR related to long-duration contracts were included in other policy claims and benefits. Upon adoption of ASU 2018-12, the Company revised prior period amounts to conform to the current period’s presentation. See Note 2 – “Impact of New Accounting Standard” for additional information. Interest-Sensitive Contract Liabilities and Policyholder Account Balances Liabilities for future benefits on interest-sensitive life and investment-type contract liabilities are carried at the accumulated contract holder values without reduction for potential surrender or withdrawal charges. The Company reinsures asset-intensive products, including annuities and corporate-owned life insurance. The investment portfolios for these products are segregated for management purposes within the general account of the respective legal entity. The liabilities under asset-intensive insurance contracts or reinsurance contracts reinsured on a coinsurance basis are included in interest-sensitive contract liabilities on the condensed consolidated balance sheets. Asset-intensive contracts principally include individual fixed annuities in the accumulation phase, single premium immediate annuities, with no significant life contingency, equity-indexed annuities, individual variable annuities, corporate-owned life, and interest-sensitive whole life insurance contracts. Interest-sensitive contract liabilities are equal to (i) policy account values, which consist of an accumulation of gross premium payments; (ii) credited interest less expenses, mortality charges, and withdrawals; and (iii) fair value adjustments relating to business combinations. Liabilities for immediate annuities are calculated as the present value of the expected cash flows, with the locked-in discount rate determined such that there is no gain or loss at inception. Equity-indexed annuity contracts reinsured by the Company allow the contract holder to elect an interest rate return or an equity market component where interest credited is based on the performance of common stock market indices, such as the S&P 500 Index ® , the Dow Jones Industrial Average, or the NASDAQ. The equity market option is considered an embedded derivative, similar to a call option, which is reflected at fair value on the condensed consolidated balance sheets in interest-sensitive contract liabilities. The fair value of embedded derivatives is computed based on a projection of future equity option costs using a budget methodology, discounted back to the balance sheet date using current market indicators of volatility and interest rates. Changes in the fair value of the embedded derivatives are included as a component of interest credited on the condensed consolidated statements of income (loss). The Company reviews its estimates of actuarial liabilities for interest-sensitive contract liabilities and compares them with its actual experience. Differences between actual experience and the assumptions used in pricing these guarantees and benefits and in the establishment of the related liabilities result in variances in profit and could result in losses. The effects of changes in such estimated liabilities are included in the results of operations in the period in which the changes occur. Market Risk Benefits Market risk benefits are contracts or contract features that both provide protection to the contract holder from other-than-nominal capital market risk and expose the Company to other-than-nominal capital market risk. Market risk benefits are measured at fair value using an option-based valuation model based on current net amounts at risk, market data, Company experience, and other factors. Changes in fair value are recognized in net income each period with the exception of the portion of the change in fair value due to a change in the liability’s instrument-specific credit risk, which is recognized in other comprehensive income. Market risk benefits include the following contract features on certain annuity products that provide minimum guarantees to policyholders: • Guaranteed minimum income benefits (“GMIB”) provide the contract holder, after a specified period of time determined at the time of issuance of the variable annuity contract, with a minimum level of income (annuity) payments. Under the reinsurance treaty, the Company makes a payment to the ceding company equal to the GMIB net amount-at-risk at the time of annuitization. • Guaranteed minimum withdrawal benefits (“GMWB”) guarantee the contract holder a return of their purchase payment via partial withdrawals, even if the account value is reduced to zero, provided that the contract holder’s cumulative withdrawals in a contract year do not exceed a certain limit. The initial guaranteed withdrawal amount is equal to the initial benefit base as defined in the contract (typically, the initial purchase payments plus applicable bonus amounts). • Guaranteed minimum accumulation benefits (“GMAB”) provide the contract holder, after a specified period of time determined at the time of issuance of the variable annuity contract, with a minimum accumulation of their purchase payments even if the account value is reduced to zero. The initial guaranteed accumulation amount is equal to the initial benefit base as defined in the contract (typically, the initial purchase payments plus applicable bonus amounts). • Guaranteed minimum death benefits (“GMDB”) provides the beneficiary a guaranteed minimum amount upon the death of the contract holder, regardless of the account balance. The fair values of the GMIB, GMWB, GMDB and GMAB contract features are reflected in market risk benefits and are calculated based on actuarial and capital market assumptions related to the projected cash flows, including benefits and related contract charges over the lives of the contracts. These projected cash flows incorporate expectations concerning policyholder behavior, such as lapses, withdrawals and benefit selections, and capital market assumptions such as interest rates and equity market volatilities. In measuring the fair value of GMIBs, GMWBs, GMABs and GMDBs, the Company attributes a portion of the fees collected from the policyholder equal to the present value of expected future guaranteed minimum income, withdrawal and accumulation and death benefits (at inception). The changes in fair value are reported in market risk benefits remeasurement (gains) losses. Any additional fees represent “excess” fees and are reported in other revenues. These variable annuity guaranteed living and death benefits may be more costly than expected in volatile or declining equity markets or falling interest rate markets, causing an increase in market risk benefit liabilities. Deferred Policy Acquisition Costs Costs of acquiring new business, which vary with and are directly related to the production of new business, have been deferred to the extent that such costs are deemed recoverable from future premiums or gross profits. Such costs include commissions and allowances as well as certain costs of policy issuance and underwriting. Non-commission costs related to the acquisition of new and renewal insurance contracts may be deferred only if they meet the following criteria: • Incremental direct costs of a successful contract acquisition • Portions of employees’ salaries and benefits directly related to time spent performing specified acquisition activities for a contract that has been acquired or renewed • Other costs directly related to the specified acquisition or renewal activities that would not have been incurred had that acquisition contract transaction not occurred DAC related to traditional life and interest-sensitive contracts are grouped by contract type and issue year into cohorts for consistency with the groupings used in estimating the associated liability. DAC is amortized on a constant level basis for the grouped contracts over the expected term of the related contracts to approximate straight-line amortization. The constant level basis used is based on the number of policies or policy face amount of the risk assumed in the reinsurance contract. The constant level bases used for amortization are projected using mortality and actuarial assumptions for policyholder behavior that are based on the Company’s experience, industry data and other factors and are consistent with those used for the liability for future policy benefits. Changes in assumptions are reflected in DAC amortization prospectively, and actual experience relating to number of policies reinsured will likely differ from the experience previously estimated. Amortization of DAC is included in policy acquisition costs and other insurance expenses. Reinsurance Ceded Receivables The Company generally reports retrocession activity on a gross basis. Amounts paid or deemed to have been paid for reinsurance are reflected in reinsurance ceded receivables and other. Reinsurance ceded receivables related to long-duration contracts are estimated using mortality, morbidity, and persistency assumptions that are similar to the liability for future policy benefits ceded. The discount rate used to measure the ceded receivable is based on the current yields of an upper-medium grade fixed income instrument. Similar to the liability for future policy benefits, ceded receivables are grouped into annual cohorts based on the effective date of the reinsurance contract.

Accounting Changes and Error Corrections [Abstract]
New Accounting Standards	IMPACT OF NEW ACCOUNTING STANDARD As discussed in Note 1, the Company adopted ASU 2018-12 during the first quarter of 2023. The updated guidance materially changed how the Company accounts for its long-duration insurance contracts. Below is a summary of the impact of adopting ASU 2018-12: • For the liability for future policy benefits, the net transition adjustment recorded in accumulated other comprehensive income (loss) is related to the difference in the discount rate used prior to the adoption of ASU 2018-12 and the discount rate at January 1, 2021, and the removal of shadow adjustments previously recorded in accumulated other comprehensive income (loss) for the impact of unrealized gains and losses that were included in the expected gross profits amortization calculation as of the transition date of $8,593 million, pretax. • At transition, the Company identified certain cohorts in its Traditional segments where the present value of future expected benefits and expenses exceeded the sum of existing benefit reserve and the present value of future gross premiums, resulting in a decrease to retained earnings, net of reinsurance (and a corresponding increase in the liabilities for future policy benefits and reinsurance recoverable) of approximately $1,462 million, pretax. See “Impact of Adoption by Segment” for the transition impact by reportable segment. • At transition, the Company identified certain cohorts, primarily longevity swaps, where the present value of future premiums exceeded the present value of future benefits resulting in a negative liability. The elimination of the negative liability at transition resulted in a decrease to retained earnings (and a corresponding increase in the liabilities for future policy benefits) of $284 million, pretax. See “Impact of Adoption by Segment” for the transition impact by reportable segment. • For DAC, the Company removed shadow adjustments previously recorded in AOCI in the amount of $114 million, pretax, for the impact of unrealized gains and losses that were included in the pre-ASU 2018-12 expected gross profits amortization calculation as of the transition date. See “Impact of Adoption by Segment” for the transition impact by reportable segment. • For market risk benefits, the transition adjustment of $45 million, pretax, recognized in AOCI relates to the cumulative effect of changes in the instrument-specific credit risk between contract issue date and transition date. The remaining difference of $(72) million, pretax between the fair value and carrying value of the market risk benefits at transition, excluding the amounts recorded in AOCI, was recorded as an adjustment to retained earnings as of the transition date. See “Impact of Adoption by Segment” for the transition impact by reportable segment.

Liability for Future Policy Benefits and Unpaid Claims Disclosure	FUTURE POLICY BENEFITS Liability for Future Policy Benefits – Traditional Business The Company reviews actual and anticipated experience compared to the assumptions used to establish policy benefits on a quarterly basis and will update those assumptions if evidence suggests that they should be revised.

D uring the six months ended June 30, 2023 and 2022, there were no material changes made to the inputs in the market risk benefit calculations, and nonfinancial assumptions were unchanged.

Retrocession Arrangements And Reinsurance Ceded Receivables [Abstract]
Retrocession Arrangements and Reinsurance Ceded Receivables	REINSURANCE CEDED RECEIVABLES AND OTHER Retrocession reinsurance treaties do not relieve the Company from its obligations to direct writing companies. Failure of retrocessionaires to honor their obligations could result in losses to the Company. Consequently, allowances would be established for amounts deemed uncollectible. The Company regularly evaluates the financial condition of the insurance companies from which it assumes and to which it cedes reinsurance. At June 30, 2023 and December 31, 2022, no allowances were deemed necessary. Two major reinsurance companies account for approximately 77% of reinsurance ceded receivables and other as of June 30, 2023. Retrocessions are arranged through the Company’s retrocession pools for amounts in excess of the Company’s retention limit. As of June 30, 2023, all rated retrocession pool participants followed by the A.M. Best Company were rated “A- (excellent)” or better. The Company verifies retrocession pool participants’ ratings on a quarterly basis. For a majority of the retrocessionaires that were not rated, security in the form of letters of credit or trust assets have been posted. In addition, the Company performs annual financial reviews of its retrocessionaires to evaluate financial stability and performance. Included in the total reinsurance ceded receivables and other balance are $157 million and $183 million of claims recoverable, of which $12 million and $16 million were in excess of 90 days past due, as of June 30, 2023 and December 31, 2022, respectively. Also included in the total reinsurance ceded receivable and other is a deposit asset on reinsurance of $1.5 billion and $1.6 billion as of June 30, 2023 and December 31, 2022, respectively.

The Company also holds assets in trust to satisfy collateral requirements under derivative transactions and certain third-party reinsurance treaties. The following table includes fixed maturity securities pledged and received as collateral and assets in trust held to satisfy collateral requirements under derivative transactions and certain third-party reinsurance treaties as of June 30, 2023 and December 31, 2022 (dollars in millions): June 30, 2023 December 31, 2022 Amortized Estimated Amortized Estimated Fixed maturity securities pledged as collateral $ 401 $ 352 $ 355 $ 292 Fixed maturity securities received as collateral n/a 1,742 n/a 1,428 Assets in trust held to satisfy collateral requirements 32,516 29,259 31,510 27,817 The Company monitors its concentrations of financial instruments on an ongoing basis and mitigates credit risk by maintaining a diversified investment portfolio that limits exposure to any one issuer.

The amount recognized represents the difference between the amortized cost of the security and the net present value of its projected future cash flows discounted at the effective interest rate implicit in the fixed maturity security prior to the allowance for credit losses. Any remaining difference between the fair value and amortized cost is recognized in OCI. The following tables present the rollforward of the allowance for credit losses in fixed maturity securities by type for the six months ended June 30, 2023 and 2022 (dollars in millions) : Six months ended June 30, 2023: Corporate ABS CMBS Other Foreign Government Total Balance, beginning of year $ 27 $ 10 $ — $ — $ 37 Credit losses recognized on securities for which credit losses were not previously recorded 44 — 1 — 45 Reductions for securities sold during the period (10) — — — (10) Additional increases or decreases for credit losses on securities that had an allowance recorded in a previous period 1 2 — — 3 Balance, end of period $ 62 $ 12 $ 1 $ — $ 75 Six months ended June 30, 2022: Corporate ABS CMBS Other Foreign Government Total Balance, beginning of year $ 26 $ — $ 1 $ 4 $ 31 Credit losses recognized on securities for which credit losses were not previously recorded 18 5 — 1 24 Reductions for securities sold during the period (6) — — (1) (7) Additional increases or decreases for credit losses on securities that had an allowance recorded in a previous period 5 — — 2 7 Balance, end of period $ 43 $ 5 $ 1 $ 6 $ 55 Unrealized Losses for Fixed Maturity Securities Available-for-Sale The Company’s determination of whether a decline in value necessitates the recording of an allowance for credit losses includes an analysis of whether the issuer is current on its contractual payments, evaluating whether it is probable that the Company will be able to collect all amounts due according to the contractual terms of the security and analyzing the overall ability of the Company to recover the amortized cost of the investment. The following tables present the estimated fair value and gross unrealized losses for the 6,456 and 6,441 fixed maturity securities for which an allowance for credit loss has not been recorded as of June 30, 2023 and December 31, 2022, and the estimated fair value had declined and remained below amortized cost (dollars in millions).

Changes in unrealized losses are primarily driven by changes in risk-free interest rates and credit spreads.

The total recorded investment before allowance for credit losses for the modified loans were $17 million as of June 30, 2023. During the six months ended June 30, 2022, the Company restructured three mortgage loans to interest only payments, one of which was paid in full as of December 31, 2022. The total recorded investment before allowance for credit losses for mortgage loans that were modified and met the criteria of Troubled Debt Restructuring (“TDR”) was $77 million as of June 30, 2022. During the six months ended June 30, 2023, the Company converted two mortgage loans in the total amount of $36 million to owned properties through foreclosure-type transactions. The Company had one mortgage loan in the amount of $7 million that was on a nonaccrual status as of June 30, 2023. The Company had no mortgage loans that were on a nonaccrual status as of June 30, 2022. The Company did not acquire any impaired mortgage loans during the six months ended June 30, 2023 and 2022. Policy Loans The majority of policy loans are associated with one client. These policy loans present no credit risk as the amount of the loan cannot exceed the obligation due to the ceding company upon the death of the insured or surrender of the underlying policy. The provisions of the treaties in force and the underlying policies determine the policy loan interest rates. The Company earns a spread between the interest rate earned on policy loans and the interest rate credited to corresponding liabilities. Funds Withheld at Interest As of June 30, 2023, $3.6 billion of the funds withheld at interest balance is primarily associated with two clients. For reinsurance agreements written on a modco basis and certain agreements written on a coinsurance funds withheld basis, assets equal to the net statutory reserves are withheld and legally owned and managed by the ceding company and are reflected as funds withheld at interest. In the event of a ceding company’s insolvency, the Company would need to assert a claim on the assets supporting its reserve liabilities. However, the risk of loss to the Company is mitigated by its ability to offset amounts it owes the ceding company for claims or allowances against amounts owed to the Company from the ceding company. Limited Partnerships and Real Estate Joint Ventures The carrying values of limited partnerships and real estate joint ventures as of June 30, 2023 and December 31, 2022 are as follows (dollars in millions): June 30, 2023 December 31, 2022 Limited partnerships – equity method $ 928 $ 934 Limited partnerships – fair value 768 683 Limited partnerships – cost method 62 49 Real estate joint ventures 715 661 Total limited partnerships and real estate joint ventures $ 2,473 $ 2,327 Other Invested Assets Other invested assets include lifetime mortgages and derivative contracts.

Summary of Derivative Positions Derivatives, except for embedded derivatives, are included in other invested assets or other liabilities, at fair value. Embedded derivative assets and liabilities on modco or funds withheld arrangements are included on the condensed consolidated balance sheets with the host contract in funds withheld at interest or other liabilities, at fair value. Embedded derivative liabilities on indexed annuity products are included on the condensed consolidated balance sheets with the host contract in interest-sensitive contract liabilities, at fair value. The following table presents the notional amounts and gross fair value of derivative instruments prior to taking into account the netting effects of master netting agreements as of June 30, 2023 and December 31, 2022 (dollars in millions): June 30, 2023 December 31, 2022 Primary Underlying Risk Notional Carrying Value/Fair Value Notional Carrying Value/Fair Value Amount Assets Liabilities Amount Assets Liabilities Derivatives not designated as hedging instruments: Interest rate swaps Interest rate $ 1,683 $ 6 $ 4 $ 1,271 $ 2 $ 2 Interest rate options Interest rate 6,555 8 — 7,756 34 — Total return swaps Interest rate 500 25 3 500 18 — Interest rate futures Interest rate 96 — — 96 — — Equity futures Equity 241 — — 164 — — Foreign currency swaps Foreign currency 150 26 — 150 18 — Foreign currency forwards Foreign currency 850 — 28 766 50 — CPI swaps CPI 477 14 2 496 20 3 Credit default swaps Credit 1,515 4 10 1,523 2 21 Equity options Equity 306 12 — 358 38 — Synthetic GICs Interest rate 17,027 — — 17,411 — — Embedded derivatives in: Modco or funds withheld arrangements — 368 359 — 363 371 Indexed annuity products — — 472 — — 530 Total non-hedging derivatives 29,400 463 878 30,491 545 927 Derivatives designated as hedging instruments: Interest rate swaps Foreign currency/Interest rate 1,997 5 148 1,310 3 113 Foreign currency swaps Foreign currency 104 — 3 114 — — Foreign currency forwards Foreign currency 1,158 14 9 1,019 38 1 Forward bond purchase commitments Interest rate 775 1 84 407 — 96 Total hedging derivatives 4,034 20 244 2,850 41 210 Total derivatives $ 33,434 $ 483 $ 1,122 $ 33,341 $ 586 $ 1,137 Fair Value Hedges The Company designates and reports certain foreign currency swaps to hedge the foreign currency fair value exposure of foreign currency denominated assets as fair value hedges when they meet the requirements of the general accounting principles for Derivatives and Hedging . The gain or loss on the hedged item attributable to a change in foreign currency and the offsetting gain or loss on the related foreign currency swaps as of June 30, 2023 and 2022 were as follows (dollars in millions): Type of Fair Value Hedge Hedged Item Gains (Losses) Recognized for Derivatives Gains (Losses) Recognized for Hedged Items Investment Related Gains (Losses), Net For the three months ended June 30, 2023: Foreign currency swaps Foreign-denominated fixed maturity securities $ — $ — For the three months ended June 30, 2022: Foreign currency swaps Foreign-denominated fixed maturity securities $ (8) $ 8 For the six months ended June 30, 2023: Foreign currency swaps Foreign-denominated fixed maturity securities $ (3) $ 2 For the six months ended June 30, 2022: Foreign currency swaps Foreign-denominated fixed maturity securities $ (1) $ 5 Cash Flow Hedges Certain derivative instruments are designated as cash flow hedges when they meet the requirements of the general accounting principles for Derivatives and Hedging . The Company designates and accounts for the following as cash flow hedges: (i) certain interest rate swaps, in which the cash flows of assets and liabilities are variable based on a benchmark rate; (ii) certain interest rate swaps, in which the cash flows of assets are denominated in different currencies, commonly referred to as cross-currency swaps; (iii) certain interest rate swaps, in which floating rate assets are converted to fixed rate assets; and (iv) forward bond purchase commitments. The following table presents the components of AOCI, before income tax, and the condensed consolidated income statement classification where the gain or loss is recognized related to cash flow hedges for the three and six months ended June 30, 2023 and 2022 (dollars in millions): Three months ended June 30, 2023 2022 Balance, beginning of period $ (198) $ (81) Gains (losses), net deferred in other comprehensive income (loss) (32) (128) Amounts reclassified to net investment income 4 2 Amounts reclassified to interest expense (2) 1 Balance, end of period $ (228) $ (206) Six months ended June 30, 2023 2022 Balance, beginning of period $ (205) $ (22) Gains (losses), net deferred in other comprehensive income (loss) (26) (188) Amounts reclassified to net investment income 7 2 Amounts reclassified to interest expense (4) 2 Balance, end of period $ (228) $ (206) As of June 30, 2023, approximately $12 million of before-tax deferred net losses recorded in AOCI are expected to be reclassified to net investment income during the next twelve months. For the same time period, $11 million of before-tax deferred net gains on derivative instruments recorded in AOCI are expected to be reclassified to interest expense during the next twelve months. The following table presents the effect of derivatives in cash flow hedging relationships on the condensed consolidated statements of income and the condensed consolidated statements of comprehensive income for the three and six months ended June 30, 2023 and 2022 (dollars in millions): Derivative Type Gains (Losses) Deferred in OCI Gains (Losses) Reclassified into Income from AOCI Net Investment Income Interest Expense For the three months ended June 30, 2023: Interest rate $ (8) $ — $ 2 Foreign currency/interest rate (24) (4) — Total $ (32) $ (4) $ 2 For the three months ended June 30, 2022: Interest rate $ (106) $ — $ (1) Foreign currency/interest rate (22) (2) — Total $ (128) $ (2) $ (1) For the six months ended June 30, 2023: Interest rate $ 6 $ — $ 4 Foreign currency/interest rate (32) (7) — Total $ (26) $ (7) $ 4 For the six months ended June 30, 2022: Interest rate $ (170) $ — $ (2) Foreign currency/interest rate (18) (2) — Total $ (188) $ (2) $ (2) For the three and six months ended June 30, 2023 and 2022, there were no material amounts reclassified into earnings relating to instances in which the Company discontinued cash flow hedge accounting because the forecasted transaction did not occur by the anticipated date or within the additional time period permitted by the authoritative guidance for the accounting for derivatives and hedging. Hedges of Net Investments in Foreign Operations The Company uses foreign currency swaps and foreign currency forwards to hedge a portion of its net investment in certain foreign operations against adverse movements in exchange rates. The following table illustrates the Company’s net investments in foreign operations (“NIFO”) hedges and the gains (losses) deferred in OCI for the three and six months ended June 30, 2023 and 2022 (dollars in millions): Derivative Gains (Losses) Deferred in OCI Three months ended June 30, Six months ended June 30, Type of NIFO Hedge 2023 2022 2023 2022 Foreign currency swaps $ — $ 1 $ — $ 1 Foreign currency forwards (21) 38 (21) 22 Total $ (21) $ 39 $ (21) $ 23 The cumulative foreign currency translation gain recorded in AOCI related to these hedges was $189 million and $210 million as of June 30, 2023 and December 31, 2022, respectively. If a hedged foreign operation was sold or substantially liquidated, the amounts in AOCI would be reclassified to the condensed consolidated statements of income. A pro rata portion would be reclassified upon partial sale of a hedged foreign operation. There were no sales or substantial liquidations of net investments in foreign operations that would have required the reclassification of gains or losses from AOCI into investment income during the periods presented. Non-qualifying Derivatives and Derivatives for Purposes Other Than Hedging The Company uses various other derivative instruments for risk management purposes that either do not qualify or have not been elected for hedge accounting treatment. The gain or loss related to the change in fair value for these derivative instruments is recognized in investment related gains (losses), net, except where otherwise noted. A summary of the effect of non-hedging derivatives, including embedded derivatives, on the Company’s condensed consolidated statements of income for the three and six months ended June 30, 2023 and 2022 is as follows (dollars in millions): Gains (Losses) for the three months ended Type of Non-hedging Derivative Income Statement Location of Gains (Losses) 2023 2022 Interest rate swaps Investment related gains (losses), net $ (30) $ (44) Interest rate options Investment related gains (losses), net (3) (6) Total return swaps Investment related gains (losses), net 5 — Interest rate futures Investment related gains (losses), net 2 1 Equity futures Investment related gains (losses), net (10) 23 Foreign currency swaps Investment related gains (losses), net 12 11 Foreign currency forwards Investment related gains (losses), net (74) (76) CPI swaps Investment related gains (losses), net 6 (11) Credit default swaps Investment related gains (losses), net 10 (33) Equity options Investment related gains (losses), net (11) 21 Subtotal (93) (114) Embedded derivatives in: Modco or funds withheld arrangements Investment related gains (losses), net (20) (56) Indexed annuity products Interest credited (5) 44 Total non-hedging derivatives $ (118) $ (126) Gains (Losses) for the six months ended Type of Non-hedging Derivative Income Statement Location of Gains (Losses) 2023 2022 Interest rate swaps Investment related gains (losses), net $ (10) $ (96) Interest rate options Investment related gains (losses), net (26) (6) Total return swaps Investment related gains (losses), net 8 — Interest rate futures Investment related gains (losses), net 2 3 Equity futures Investment related gains (losses), net (19) 28 Foreign currency swaps Investment related gains (losses), net 12 18 Foreign currency forwards Investment related gains (losses), net (93) (99) CPI swaps Investment related gains (losses), net 7 18 Credit default swaps Investment related gains (losses), net 21 (91) Equity options Investment related gains (losses), net (25) 21 Subtotal (123) (204) Embedded derivatives in: Modco or funds withheld arrangements Investment related gains (losses), net 17 (89) Indexed annuity products Interest credited 11 80 Total non-hedging derivatives $ (95) $ (213) Credit Derivatives The following table presents the estimated fair value, maximum amount of future payments and weighted average years to maturity of credit default swaps sold by the Company at June 30, 2023 and December 31, 2022 (dollars in millions): June 30, 2023 December 31, 2022 Rating Agency Designation of Referenced Credit Obligations (1) Estimated Fair Maximum Amount of Future Payments under Credit Default Swaps (2) Weighted Average Years to Maturity (3) Estimated Fair Maximum Amount of Future Payments under Credit Default Swaps (2) Weighted Average Years to Maturity (3) AAA/AA+/AA/AA-/A+/A/A- Single name credit default swaps $ (9) $ 420 18.6 $ (18) $ 428 18.7 BBB+/BBB/BBB- Single name credit default swaps 3 155 3.1 1 155 3.3 Credit default swaps referencing indices 1 915 4.5 — 915 6.2 Subtotal 4 1,070 4.3 1 1,070 5.8 BB+/BB/BB- Single name credit default swaps (1) 25 2.7 (2) 25 3.2 Total $ (6) $ 1,515 8.2 $ (19) $ 1,523 9.4 (1) The rating agency designations are based on ratings from Standard and Poor’s (“S&P”).

Netting Arrangements and Credit Risk Certain of the Company’s derivatives are subject to enforceable master netting arrangements and reported as a net asset or liability in the condensed consolidated balance sheets. The Company nets all derivatives that are subject to such arrangements. The Company has elected to include all derivatives, except embedded derivatives, in the table below, irrespective of whether they are subject to an enforceable master netting arrangement or a similar agreement. See Note 11 – “Investments” for information regarding the Company’s securities borrowing, lending and repurchase/reverse repurchase agreements. The following table provides information relating to the netting of the Company’s derivative instruments as of June 30, 2023 and December 31, 2022 (dollars in millions): Gross Amounts Gross Amounts Net Amounts Financial Instruments/Collateral (1) Net Amount June 30, 2023: Derivative assets $ 115 $ (54) $ 61 $ (61) $ — Derivative liabilities 291 (54) 237 (237) — December 31, 2022: Derivative assets 223 (53) 170 (170) — Derivative liabilities 236 (53) 183 (183) — (1) Includes initial margin posted to a central clearing partner for financial instruments and excludes the excess of collateral received/pledged from/to the counterparty. The Company may be exposed to credit-related losses in the event of non-performance by counterparties to derivative financial instruments. Generally, the credit exposure of the Company’s derivative contracts is limited to the fair value and accrued interest of non-collateralized derivative contracts in an asset position at the reporting date. As of June 30, 2023, the Company had credit exposure of $14 million. Derivatives may be exchange-traded or they may be privately negotiated contracts, which are referred to as over-the-counter (“OTC”) derivatives. Certain of the Company’s OTC derivatives are cleared and settled through central clearing counterparties (“OTC cleared”) and others are bilateral contracts between two counterparties. The Company manages its credit risk related to OTC derivatives by entering into transactions with creditworthy counterparties, maintaining collateral arrangements and through the use of master netting agreements that provide for a single net payment to be made by one counterparty to another at each due date and upon termination. The Company is only exposed to the default of the central clearing counterparties for OTC cleared derivatives, and these transactions require initial and daily variation margin collateral postings. Exchange-traded derivatives are settled on a daily basis, thereby reducing the credit risk exposure in the event of non-performance by counterparties to such financial instruments.

Fair Value Disclosures [Abstract]
Fair Value Disclosures	Fair Value Measurement General accounting principles for Fair Value Measurements and Disclosures define fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. These principles also establish a three-level fair value hierarchy that requires an entity to maximize the use of observable inputs and to minimize the use of unobservable inputs when measuring fair value: Level 1 – Unadjusted quoted prices in active markets for identical assets or liabilities. Active markets are defined through various characteristics for the measured asset/liability, such as having many transactions and narrow bid/ask spreads. Level 2 – Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or market standard valuation techniques and assumptions that use significant inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the related assets or liabilities and include those whose value is determined using market standard valuation techniques described above. Prices are determined using valuation methodologies such as discounted cash flow models and other similar techniques that require management’s judgment or estimation in developing inputs that are consistent with those other market participants would use when pricing similar assets and liabilities. For a discussion of the Company’s valuation methodologies for assets and liabilities measured at fair value and the fair value hierarchy, see Note 6 – “Fair Value of Assets and Liabilities” in the Notes to Consolidated Financial Statements included in the Company’s 2022 Annual Report. See Note 8 – “Market Risk Benefits” for information about fair value measurement of market risk benefits. Assets and Liabilities by Hierarchy Level Assets and liabilities measured at fair value on a recurring basis as of June 30, 2023 and December 31, 2022 are summarized below (dollars in millions): June 30, 2023: Fair Value Measurements Using: Total Level 1 Level 2 Level 3 Assets: (1) Fixed maturity securities available-for-sale: Corporate $ 36,178 $ — $ 31,524 $ 4,654 Canadian government 3,752 — 3,752 — Japanese government 3,046 — 3,046 — ABS 4,165 — 2,826 1,339 CMBS 1,699 — 1,642 57 RMBS 1,037 — 1,036 1 U.S. government 1,366 1,272 86 8 State and political subdivisions 1,109 — 1,088 21 Other foreign government 3,884 — 3,849 35 Total fixed maturity securities available-for-sale 56,236 1,272 48,849 6,115 Equity securities 136 68 — 68 Funds withheld at interest – embedded derivatives (353) — — (353) Funds withheld at interest 53 — — 53 Cash equivalents 1,329 1,326 3 — Short-term investments 193 93 94 6 Other invested assets: Derivatives 61 — 61 — Other 21 — 21 — Total other invested assets 82 — 82 — Total $ 57,676 $ 2,759 $ 49,028 $ 5,889 Liabilities: Interest-sensitive contract liabilities – embedded derivatives $ 472 $ — $ — $ 472 Other liabilities: Funds withheld at interest – embedded derivatives (362) — — (362) Derivatives 237 — 237 — Total $ 347 $ — $ 237 $ 110 (1) Excludes limited partnerships that are measured at estimated fair value using the NAV per share (or its equivalent) as a practical expedient.

As of December 31, 2022, the fair value of such investments was $683 million. Quantitative Information Regarding Internally Priced Assets and Liabilities The following table presents quantitative information about significant unobservable inputs used in Level 3 fair value measurements that are developed internally by the Company as of June 30, 2023 and December 31, 2022 (dollars in millions): Estimated Fair Value Valuation Technique Unobservable Inputs Range (Weighted Average) June 30, 2023 December 31, 2022 June 30, 2023 December 31, 2022 Assets: Corporate $ 4 $ 25 Market comparable securities Liquidity premium N/A 1% EBITDA Multiple 5.3x-8.0x (6.0x) 5.3x ABS 267 274 Market comparable securities Liquidity premium 0-18% (2%) 0-18% (2%) U.S. government 8 9 Market comparable securities Liquidity premium 0-1% (1%) 0-1% (1%) Equity securities 21 9 Market comparable securities Liquidity premium 1% N/A EBITDA Multiple 8.4x-11.2x (10.4x) 8.4x-11.2x (9.6x) Funds withheld at interest – embedded derivatives (16) (34) Total return swap Mortality 0-100% (3%) 0-100% (3%) Lapse 0-35% (15%) 0-35% (17%) Withdrawal 0-5% (4%) 0-5% (4%) CVA 0-5% (0%) 0-5% (0%) Crediting rate 1-4% (2%) 1-4% (2%) Liabilities: Interest-sensitive contract liabilities – embedded derivatives – indexed annuities 472 530 Discounted cash flow Mortality 0-100% (3%) 0-100% (3%) Lapse 0-35% (14%) 0-35% (16%) Withdrawal 0-5% (4%) 0-5% (3%) Option budget projection 1-4% (2%) 1-4% (2%) Changes in Level 3 Assets and Liabilities Assets and liabilities transferred into Level 3 are due to a lack of observable market transactions and price information. Transfers out of Level 3 are primarily the result of the Company obtaining observable pricing information or a third-party pricing quotation that appropriately reflects the fair value of those assets and liabilities. For further information on the Company’s valuation processes, see Note 6 – “Fair Value of Assets and Liabilities” in the Notes to Consolidated Financial Statements included in the Company’s 2022 Annual Report.

Nonrecurring Fair Value Measurements The Company has certain assets subject to measurement at fair value on a nonrecurring basis, in periods subsequent to their initial recognition if they are determined to be impaired. During the six months ended June 30, 2023 and 2022, the Company did not have any material assets that were measured at fair value due to impairment. Fair Value of Financial Instruments Carried at Other Than Fair Value The following table presents the carrying values and estimated fair values of the Company’s financial instruments, which were not measured at fair value on a recurring basis, as of June 30, 2023 and December 31, 2022 (dollars in millions). For additional information regarding the methods and significant assumptions used by the Company to estimate these fair values, see Note 6 – “Fair Value of Assets and Liabilities” in the Notes to Consolidated Financial Statements included in the Company’s 2022 Annual Report. This table excludes any payables or receivables for collateral under repurchase/reverse repurchase agreements and other transactions. The estimated fair value of the excluded amount approximates carrying value as they equal the amount of cash collateral received/paid.

Income Tax Disclosure [Abstract]
Income Tax Disclosure [Text Block]	On August 16, 2022, the Inflation Reduction Act of 2022 (“the Act”) was enacted in the U.S. The Act includes law changes relating to tax, climate change, energy and health care. In particular, for tax years ending after December 31, 2022, the Act imposes a 15% minimum tax on adjusted financial statement income for “applicable corporations” with average financial statement income exceeding $1 billion for the previous 3-year period ending in 2022 or after. Based on the current guidance, the Company is not an applicable corporation for 2023. The Act also imposes a 1% excise tax on stock buybacks of a publicly traded corporation. The Act is not expected to have a material impact to the Company’s tax expense. The effective tax rate for the three and six months ending June 30, 2023, was 21.7% and 25.2% on pre-tax income. The tax rate differed from the U.S. statutory rate primarily due to income earned in jurisdictions with tax rates greater than the U.S. statutory tax rate, and adjustments to the valuation allowance. These increases were partially offset with benefits received from tax credits generated during the year. The effective tax rate for the three and six months ending June 30, 2022, was 27.7% and 26.8%. The Company’s effective tax rate for the three and six months ended June 30, 2022, differed from the U.S. statutory rate of 21% primarily due to income in jurisdictions with tax rates higher than the U.S., tax basis adjustments, adjustments to the valuation allowance and foreign tax credits.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingent Liabilities	Commitments Funding of Investments The Company’s commitments to fund investments as of June 30, 2023 and December 31, 2022, are presented in the following table (dollars in millions): June 30, 2023 December 31, 2022 Limited partnerships and real estate joint ventures $ 1,128 $ 937 Mortgage loans 147 137 Bank loans and private placements 631 682 Lifetime mortgages 1 59 The Company anticipates that the majority of its current commitments will be invested over the next five years; however, these commitments could become due any time at the request of the counterparties. Bank loans and private placements are included in fixed maturity securities available-for-sale. The Company has an immaterial liability, included in other liabilities, for expected credit losses associated with unfunded commitments as of June 30, 2023 and December 31, 2022. Funding Agreements Federal Home Loan Bank of Des Moines The Company is a member of the FHLB and, through membership, has issued funding agreements to the FHLB in exchange for cash advances. As of June 30, 2023 and December 31, 2022, the Company had $1.3 billion of FHLB funding agreements outstanding. The Company is required to provide collateral in excess of the funding agreement amounts outstanding, considering any discounts to the securities posted and prepayment penalties. Funding Agreement Backed Notes The Company’s Funding Agreement Backed Notes (“FABN”) program allows RGA Global Funding, a special-purpose, unaffiliated statutory trust, to offer its senior secured medium-term notes to investors. RGA Global Funding uses the net proceeds from each sale to purchase one or more funding agreements from the Company. As of both June 30, 2023 and December 31, 2022, the Company had $900 million of FABN agreements outstanding and are included within interest-sensitive contract liabilities. Contingencies Litigation The Company is subject to litigation and regulatory investigations or actions from time to time. Based on current knowledge, management does not believe that loss contingencies arising from pending legal, regulatory and governmental matters will have a material adverse effect on the financial condition, results of operations or cash flows of the Company. However, in light of the inherent uncertainties involved in future or pending legal, regulatory and governmental matters, some of which are beyond the Company’s control, and indeterminate or potentially substantial amount of damages sought in any such matters, an adverse outcome could be material to the Company’s financial condition, results of operations or cash flows for any particular reporting period. A legal reserve is established when the Company is notified of an arbitration demand, litigation or regulatory action or is notified that an arbitration demand, litigation or regulatory action is imminent, it is probable that the Company will incur a loss as a result and the amount of the probable loss is reasonably capable of being estimated. Other Contingencies The Company indemnifies its directors and officers as provided in its charters and by-laws. Since this indemnity generally is 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 due under this indemnity in the future. Guarantees Statutory Reserve Support Certain RGA subsidiaries have committed to provide statutory reserve support to third parties, in exchange for a fee, by funding loans if certain defined events occur. Such statutory reserves are required under the U.S. Valuation of Life Policies Model Regulation (commonly referred to as Regulation XXX for term life insurance policies and Regulation A-XXX for universal life secondary guarantees). In addition, certain subsidiaries have also committed to provide capital support to a third party, in exchange for a fee, by agreeing to assume real estate leases in the event of a severe and prolonged decline in the commercial lease market. Upon assumption of a lease, the Company would recognize a right to use asset and lease obligation. As of June 30, 2023, the Company does not believe that it will be required to provide any funding under these commitments as the occurrence of the defined events is considered remote. The following table presents the maximum potential obligation for these commitments as of June 30, 2023 (dollars in millions): Commitment Period Maximum Potential Obligation 2034 $ 1,243 2035 1,922 2036 3,599 2037 6,850 2038 800 2039 8,751 2041 720 2046 3,000

Segment Information	Jun. 30, 2023
Segment Reporting [Abstract]
Segment Information	The accounting policies of the segments are the same as those described in Note 2 – “Significant Accounting Policies and Pronouncements” in the Notes to Consolidated Financial Statements included in the Company’s 2022 Annual Report. The Company measures segment performance primarily based on profit or loss from operations before income taxes. There are no intersegment reinsurance transactions and the Company does not have any material long-lived assets. The Company allocates capital to its segments based on an internally developed economic 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 considers the unique and specific nature of the risks inherent in the Company’s businesses. As a result of the economic capital allocation process, a portion of investment income is attributed to the segments based on the level of allocated capital.

Insurance [Abstract]
Liability for Future Policy Benefit, Activity	Liability for Future Policy Benefits – Traditional Business The Company reviews actual and anticipated experience compared to the assumptions used to establish policy benefits on a quarterly basis and will update those assumptions if evidence suggests that they should be revised. During the six months ended June 30, 2023, and 2022, there were no material changes to the Traditional business assumptions. The Company expects to complete its annual review and any necessary updates of cash flow assumptions used to calculate the liability for future policy benefits during the third quarter of each year. Updates may occur in other quarters if information becomes available during the quarter that indicates an assumption update is necessary. The following tables provide the balances of and changes in the Company’s liability for future policy benefits for long-duration reinsurance contracts for its Traditional business, which primarily consists of individual life, group life and critical illness reinsurance for the six months ended June 30, 2023 and 2022 (dollars in millions): Six months ended June 30, 2023: U.S. and Latin America – Traditional Canada – Traditional Europe, Middle East and Africa – Traditional Asia Pacific – Traditional Present Value of Expected Net Premiums Beginning of year balance at original discount rate $ 74,207 $ 21,330 $ 14,244 $ 40,506 Effect of changes in cash flow assumptions — — — (8) Effect of actual variances from expected experience (83) 347 (51) 50 Adjusted balance, beginning of year 74,124 21,677 14,193 40,548 Issuances (1) 1,653 240 610 1,264 Interest accrual (2) 1,710 370 243 515 Net premiums collected (3) (2,534) (466) (696) (997) Derecognition (4) (35) — — — Foreign currency translation 3 498 445 (914) Ending balance at original discount rate 74,921 22,319 14,795 40,416 Effect of changes in discount rate assumptions (5,424) (4,436) (3,427) (10,296) Balance, end of period $ 69,497 $ 17,883 $ 11,368 $ 30,120 Present Value of Expected Future Policy Benefits Beginning of year balance at original discount rate $ 85,285 $ 24,655 $ 15,454 $ 44,785 Effect of changes in cash flow assumptions — — — (8) Effect of actual variances from expected experience (49) 347 (44) 27 Adjusted balance, beginning of year 85,236 25,002 15,410 44,804 Issuances (1) 1,653 240 610 1,264 Interest accrual (2) 1,972 474 259 588 Benefit payments (5) (2,801) (507) (682) (894) Derecognition (4) (54) — — — Foreign currency translation 4 580 488 (979) Ending balance at original discount rate 86,010 25,789 16,085 44,783 Effect of changes in discount rate assumptions (6,721) (3,626) (3,669) (12,197) Balance, end of period $ 79,289 $ 22,163 $ 12,416 $ 32,586 Liability for future policy benefits $ 9,792 $ 4,280 $ 1,048 $ 2,466 Less: reinsurance recoverable (407) (285) (36) (99) Net liability for future policy benefits $ 9,385 $ 3,995 $ 1,012 $ 2,367 Weighted-average duration of the liability (in years) 12 15 8 17 Weighted-average interest accretion rate 4.7 % 3.6 % 3.4 % 2.6 % Weighted-average current discount rate 5.1 % 4.6 % 6.1 % 4.2 % (1) Issuances: The present value, using the original discount rate, of the expected net premiums or the expected future policy benefits related to new reinsurance contracts that became effective during the current period and new policies assumed on existing contracts.
