Organization, Consolidation and Presentation of Financial Statements [Abstract]
Business 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”) engage 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. Reinsurance is an arrangement under which an insurance company, the reinsurer, agrees to indemnify another insurance company, the ceding company, for all or a portion of the insurance risks underwritten by the ceding company. Reinsurance is designed to: (i) reduce the net amount at risk on individual risks, thereby enabling the ceding company to increase the volume of business it can underwrite, as well as increase the maximum risk it can underwrite on a single risk; (ii) enhance the ceding company’s financial strength and surplus position; (iii) stabilize operating results by leveling fluctuations in the ceding company’s loss experience; and (iv) assist the ceding company in meeting applicable regulatory requirements. Basis of Presentation The consolidated financial statements of the Company have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”). The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosures of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The most significant estimates include those used in determining the following: • Premiums receivable; • Future policy benefits and incurred but not reported claims; • Income taxes; • Valuation of investments, investment allowance for credit losses and investment impairments; • Valuation of embedded derivatives and market risk benefits. Actual results could differ materially from the estimates and assumptions used by management. The accompanying consolidated financial statements include the accounts of RGA and its subsidiaries, all of which are wholly owned, and any variable interest entities where the Company is the primary beneficiary. The Company evaluates variable interest entities in accordance with the general accounting principles for Consolidation . 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. Intercompany balances and transactions have been eliminated. There were no subsequent events that would require disclosure or adjustments to the accompanying consolidated financial statements through the date the consolidated financial statements were issued.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	SIGNIFICANT ACCOUNTING POLICIES AND PRONOUNCEMENTS The following table includes the Company’s significant accounting policies with references to the notes providing additional information on such policies and critical accounting estimates related to such policies. Accounting Policy Page Insurance Related Activities: Premium and Fee Revenue and Receivable Recognition 97 Future Policy Benefits 98 Interest-Sensitive Contract Liabilities and Policyholder Account Balances 99 Unpaid Claims and Claim Expense – Short-Duration Contracts 99 Market Risk Benefits 99 Deferred Policy Acquisition Costs 100 Reinsurance Ceded Receivables 100 Investments 101 Derivative Instruments 104 Fair Value Measurements 105 Income Tax 105 Other Accounting Policies 106 Insurance Related Activities Premium and Fee Revenue and Receivable Recognition Premium and Fee Revenue Life and health premiums are recognized as revenue when due from the insured and are reported net of amounts retroceded. Benefits and expenses are reported net of amounts retroceded and are associated with earned premiums so that profits are recognized over the life of the related contract. This association is accomplished through the provision for future policy benefits and the amortization of deferred policy acquisition costs. Other revenue includes items such as certain treaty recapture fees related to short duration products, fees associated with financial reinsurance and policy changes on interest-sensitive and investment-type products that the Company reinsures. Any fees that are collected in advance of the period benefited are deferred and recognized over the period benefited. The Company reinsures medical, disability, life and other products for fixed period of short-duration, typically one to three years. Premiums for short-duration products are recognized over the coverage period in proportion to the amount of insurance protection provided. For certain reinsurance transactions involving the reinsurance of in force blocks of business, the ceding company pays a premium equal to the initial required reserve (future policy benefit). In such transactions, for income statement presentation, the Company nets the expense associated with the establishment of the reserve against the premiums from the transaction. Premiums related to pension risk transfer transactions are recognized when due, and partially offset by an increase in the liability for future policy benefits. Revenues for interest-sensitive and investment-type products consist of investment income, policy charges for the cost of insurance, policy administration, and surrender charges that have been assessed against policy account balances during the period. Interest-sensitive contract liabilities for these products represent policy account balances before applicable surrender charges. Policy benefits and claims that are charged to expenses include claims incurred in the period in excess of related policy account balances and interest credited to policy account balances. Interest is credited to policyholder account balances according to terms of the policies or contracts. For each of its reinsurance contracts, the Company must determine if the contract provides indemnification against loss or liability relating to insurance risk, in accordance with GAAP. The Company must review all contractual features, particularly those that may limit the amount of insurance risk to which the Company is subject or features that delay the timely reimbursement of claims. If the Company determines that a contract does not expose it to a reasonable possibility of a significant loss from insurance risk, the Company records the contract on a deposit method of accounting with any net amount receivable reflected as an asset within premiums receivable and other reinsurance balances, and any net amount payable reflected as a liability within other reinsurance balances. Fees earned on the contracts are reflected as other revenues, rather than premiums. Premium Receivable Premiums are accrued when due and in accordance with information received from the ceding company. When the Company enters into a new reinsurance agreement, it accrues premium based on the terms of the reinsurance treaty. Similarly, when a ceding company fails to report information on a timely basis, the Company records accruals based on the terms of the reinsurance treaty as well as historical experience. Other management estimates include adjustments for increased in force on existing treaties, lapsed premiums given historical experience, the financial health of specific ceding companies, collateral value and the legal right of offset on related amounts (i.e., allowances and claims) owed to the ceding company. Under the legal right of offset provisions in its reinsurance treaties, the Company can withhold payments for allowances and claims from unpaid premiums. Based on its review of these factors and historical experience, the Company did not believe a provision for doubtful accounts was necessary as of December 31, 2024 or 2023. Future Policy Benefits Utilizing the net premium model, a liability for future policy benefits for life, pension risk transfer transactions, 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 completed 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 2024 and 2023. 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 and pension risk transfer transactions 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 consolidated statements of income. The locked-in discount curve at contract inception for contracts entered into after January 1, 2021, 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 January 1, 2021, are 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. 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 consolidated balance sheets. 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 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 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 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. Unpaid Claims and Claim Expense – Short-Duration Contracts The Company provides reinsurance of medical, disability, life and other products for a fixed period of short-duration, typically one to three years. Under the short-duration insurance accounting model, claims or benefits are recognized when insured events occur, based on the ultimate cost to settle the claim, and are adjusted to reflect changes in estimates during the life of the contract. The estimated cost to settle the claim is based on actuarial assumptions for similar claims. The Company also establishes an incurred but not reported (“IBNR”) liability based on historical reporting patterns. 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 (loss). 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. Eligible deferred policy acquisition costs related to short-duration contracts are capitalized and amortized in proportion to premium. 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 for traditional business are grouped into annual cohorts based on the effective date of the reinsurance contract. Given the unique risks and highly customizable nature of the financial solutions business and pension risk transfer transactions, they are not aggregated with other reinsurance contracts for the purposes of calculating the ceded receivable. Investments Fixed Maturity Securities Fixed maturity securities classified as available-for-sale are reported at fair value and are so classified based upon the possibility that such securities could be sold prior to maturity if that action enables the Company to execute its investment philosophy and appropriately match investment results to operating and liquidity needs. Unrealized gains and losses on fixed maturity securities classified as available-for-sale, less applicable deferred income taxes, are recorded in other comprehensive income (loss) (“OCI”). Investment income is recognized as it accrues or is legally due. Realized gains and losses on sales of investments are included in investment related gains (losses), net, as are changes in allowance for credit losses and impairments. The cost of investments sold is primarily determined based upon the specific identification method. Equity Securities Equity securities are carried at fair value and realized and unrealized gains and losses are included in investment related gains (losses), net. Mortgage Loans Mortgage loans are carried at unpaid principal balances, net of any unamortized premium or discount, unamortized balance of loan origination fees and expenses, and allowance for credit losses. Interest income is accrued on the principal amount of the mortgage loan based on its contractual interest rate. Amortization of premiums, discounts, and loan origination fees are recorded using the effective yield method. The Company accrues interest on loans until it is probable the Company will not receive interest, or the loan is 90 days past due. Interest income, amortization of premiums, accretion of discounts, amortization of loan origination fees and prepayment fees are reported in net investment income. Policy Loans Policy loans are reported at the unpaid principal balance. Interest income on such loans is recorded as earned using the contractually agreed-upon interest rate. These policy loans present no credit risk because the amount of the loan cannot exceed the obligation due the ceding company upon the death of the insured or surrender of the underlying policy. Funds Withheld at Interest Funds withheld at interest represent amounts contractually withheld by ceding companies in accordance with reinsurance agreements. For agreements written on a modified coinsurance (“modco”) basis and agreements written on a coinsurance funds withheld basis, assets that support the net statutory reserves or as defined in the treaty, are withheld and legally owned by the ceding company. Interest, recorded in net investment income, accrues to these assets at calculated rates as defined by the treaty terms. Changes in the value of the equity options held within the funds withheld portfolio associated with equity-indexed annuity treaties are reflected in net investment income. Limited Partnerships and Real Estate Joint Ventures Limited partnerships and real estate joint ventures, in which the Company has more than a minor influence over the investee’s operations, are reported using the equity method of accounting. Contributions paid by the Company increase carrying value and distributions received by the Company reduce carrying value. 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. Limited partnerships, in which the Company has a minor ownership interest in or virtually no influence over the investee’s operations, are primarily carried at estimated fair value. If a readily determinable fair value is not available, the Company uses the net asset value ("NAV") per share. Changes in estimated fair value are included in investment related gains (losses), net. Certain other limited partnerships are carried at cost less impairment. Short-Term Investments Short-term investments represent investments with remaining maturities of one year or less, but greater than three months, at the time of acquisition and are stated at estimated fair value or amortized cost, which approximates estimated fair value. Interest on short-term investments is recorded in net investment income. Other Invested Assets In addition to derivative contracts discussed below, other invested assets include Federal Home Loan Bank common stock, unit-linked investments, lifetime mortgages, and real estate held for investment. FHLB common stock is carried at cost. The fair value option (“FVO”) was elected for contractholder-directed investments supporting unit-linked variable annuity type liabilities that do not qualify for presentation and reporting as separate accounts. Changes in estimated fair value of unit-linked investments are included in net investment income. Lifetime mortgages are carried at unpaid principal balances, net of any unamortized premium or discount, unamortized balance of loan origination fees and expenses, and allowance for credit losses. Interest income is accrued on the principal amount of the lifetime mortgage based on its contractual interest rate. Real estate held for investment, including related improvements, is carried at cost less accumulate depreciation. Depreciation is calculated on a straight-line basis over the estimated useful life of the property. The Company’s real estate held for investment is primarily acquired upon foreclosure of mortgage loans and is recorded at estimated fair value at the time of foreclosure. The carrying value of real estate held for investment is adjusted for impairments whenever events or changes in circumstances indicate the carrying amount of the asset may not be recoverable. Such impairment adjustments are recorded in investment related gains (losses), net. Securities Lending and Repurchase/Reverse Repurchase Agreements The Company participates in securities lending programs whereby securities, which are not reflected on the Company’s consolidated balance sheets, are borrowed from third parties. The borrowed securities are used to provide collateral under affiliated reinsurance transactions. The Company is generally required to maintain a minimum of 100% to 110% of the fair value, or par value under certain programs, of the borrowed securities as collateral. The collateral generally consists of securities pledged to the third parties or rights to reinsurance treaty cash flows. If cash flows from the reinsurance treaties are insufficient to maintain the minimum collateral requirement, the Company may substitute cash or securities to meet the requirement. The Company participates in a securities lending program whereby securities, reflected as investments on the Company’s consolidated balance sheets, are loaned to a third party. In return, the Company receives securities from the third party, with an estimated fair value generally equal to 105% of the securities lent. The securities received as collateral are not reflected on the Company’s consolidated balance sheets. The Company participates in repurchase/reverse repurchase programs whereby securities, reflected as investments on the Company’s consolidated balance sheets, are sold to third parties. In return, the Company purchases securities from the third parties. Under the agreements the Company’s value of the securities sold is generally equal to 100% to 108% of the estimated fair value of the securities purchased. The securities purchased under reverse repurchase agreements are not reflected on the Company’s consolidated balance sheets. Securities sold under such transactions may be sold or re-pledged by the transferee. The Company participates in repurchase programs, whereby securities, reflected as investments on the Company’s consolidated balance sheets are sold to a third party. Under these agreements, the Company receives cash in an amount generally equal to 72% to 100% of the estimated fair value of the securities sold at the inception of the transaction, with a simultaneous agreement to repurchase such securities at a future date or on demand in an amount equal to the cash initially received plus interest. The Company monitors the ratio of the cash held to the estimated fair value of the securities sold throughout the duration of the transaction and additional cash or securities are provided or obtained as necessary. Securities sold under such transactions may be sold or re-pledged by the transferee. The obligation to repurchase bonds is reflected in other liabilities. Allowance for Credit Losses and Impairments Fixed Maturity Securities The Company identifies fixed maturity securities that could result in a credit loss by monitoring market events that could impact issuers’ credit ratings, business climates, management changes, litigation, government actions and other similar factors. The Company also monitors late payments, pricing levels, rating agency actions, key financial ratios, financial statements, revenue forecasts and cash flow projections as indicators of credit issues. The Company reviews all securities to determine whether a decline in fair value below amortized cost has resulted from a credit loss and whether an allowance for credit loss should be recognized. In making this determination, the Company considers relevant facts and circumstances including: (1) the reasons for the decline in fair value; (2) the issuer’s financial position and access to capital; and (3) the Company’s intent to sell a security or whether it is more likely than not it will be required to sell the security before the recovery of its amortized cost that, in some cases, may extend to maturity. If the Company intends to sell a security or it is more likely than not that it would be required to sell a security before the recovery of its amortized cost, less any recorded credit loss, it recognizes an impairment loss in investment related gains (losses), net for the difference between amortized cost and fair value. Credit impairments and changes in the allowance for credit losses on fixed maturity securities are reflected in investment related gains (losses), net, while non-credit impairment losses are recognized in other comprehensive income (loss) (“OCI”). The Company estimates the amount of the credit loss component of a fixed maturity security impairment as the difference between amortized cost and the present value of the expected cash flows of the security. The Company excludes accrued interest from the amortized cost and the present value of the expected cash flows of the security. The present value is determined using the best estimate cash flows discounted at the effective interest rate implicit to the security at the date of purchase or the current yield to accrete an asset-backed or floating rate secur

Insurance [Abstract]
Future Policy Benefits	FUTURE POLICY BENEFITS 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. It is the Company’s policy to complete its annual assumption review during the third quarter of each year. However, updates may occur in other quarters if information becomes available during the quarter that indicates an assumption update is necessary. Traditional Business Significant assumptions used to compute the liability for future policy benefits for the Traditional business include mortality, morbidity, lapse rates and discount rates (both accretion and current). During 2024 and 2023, the Company completed its annual assumption review resulting in a $39 million and $85 million increase in the Company’s liability for future policy benefits for its Traditional business during 2024 and 2023, respectively. The increase in the liability in 2024 and 2023 was primarily the result of updating the mortality and lapse assumptions used to measure the liability for future policy benefits. The Company also updated the underlying market data used to determine the current discount rate resulting in changes to the discount rate assumption used to measure the net liability for future policy benefits. 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 years ended December 31, 2024 and 2023 (dollars in millions): For the year ended December 31, 2024: 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 $ 76,943 $ 22,689 $ 15,328 $ 42,741 Effect of changes in cash flow assumptions 67 (592) 187 975 Effect of actual variances from expected experience (455) 333 593 368 Adjusted balance, beginning of year 76,555 22,430 16,108 44,084 Issuances (1) 5,844 549 1,144 3,965 Interest accrual (2) 3,494 741 532 1,140 Net premiums collected (3) (6,230) (994) (1,513) (2,258) Derecognition (4) (1,776) — — — Foreign currency translation (6) (1,798) (360) (2,130) Ending balance at original discount rate 77,881 20,928 15,911 44,801 Effect of changes in discount rate assumptions (8,683) (4,042) (2,767) (12,583) Balance, end of period $ 69,198 $ 16,886 $ 13,144 $ 32,218 Present Value of Expected Future Policy Benefits Beginning of year balance at original discount rate $ 89,036 $ 26,275 $ 16,756 $ 47,370 Effect of changes in cash flow assumptions 36 (620) 212 1,048 Effect of actual variances from expected experience (639) 331 601 289 Adjusted balance, beginning of year 88,433 25,986 17,569 48,707 Issuances (1) 5,844 549 1,135 3,989 Interest accrual (2) 4,078 955 574 1,305 Benefit payments (5) (5,853) (1,085) (1,501) (2,024) Derecognition (4) (1,783) — — — Foreign currency translation (8) (2,096) (412) (2,265) Ending balance at original discount rate 90,711 24,309 17,365 49,712 Effect of changes in discount rate assumptions (10,975) (3,323) (3,101) (14,891) Balance, end of period $ 79,736 $ 20,986 $ 14,264 $ 34,821 Liability for future policy benefits $ 10,538 $ 4,100 $ 1,120 $ 2,603 Less: reinsurance recoverable (810) (263) (22) (74) Net liability for future policy benefits $ 9,728 $ 3,837 $ 1,098 $ 2,529 Weighted-average duration of the liability (in years) 11 14 8 15 Weighted-average interest accretion rate 4.6 % 3.6 % 3.4 % 2.7 % Weighted-average current discount rate 5.7 % 4.8 % 5.6 % 4.7 % (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.

The Company’s Traditional business actual-to-expected variances, the effects of changes in cash flow assumptions and the effects of changes in discount rate assumption for the years ended December 31, 2024 and 2023 are summarized in the tables below: For the year ended December 31, 2024: Segment Liability for future policy benefits at original discount rate Changes in cash flow assumptions Actual-to-expected variance Impact of updating discount rate recognized in OCI U.S. and Latin America – Traditional $12.8 billion $(31) million $(184) million $(1.2) billion Canada – Traditional $3.4 billion $(28) million $(2) million $(152) million Europe, Middle East and Africa – Traditional $1.5 billion $25 million $8 million $(115) million Asia Pacific – Traditional $4.9 billion $73 million $(79) million $(343) million For the year ended December 31, 2023: Segment Liability for future policy benefits at original discount rate Changes in cash flow assumptions Actual-to-expected variance Impact of updating discount rate recognized in OCI U.S. and Latin America – Traditional $12.1 billion $17 million $82 million $458 million Canada – Traditional $3.6 billion $12 million $9 million $245 million Europe, Middle East and Africa – Traditional $1.4 billion $47 million $13 million $(50) million Asia Pacific – Traditional $4.6 billion $9 million $(45) million $(34) million Financial Solutions Business Significant assumptions used to compute the liability for future policy benefits for the Financial Solutions business include mortality, morbidity, lapse rates and discount rates (both accretion and current). During 2024 and 2023, the Company completed its annual assumption review resulting in a $20 million increase and $78 million decrease in the Company’s liability for future policy benefits for its Financial Solutions business during 2024 and 2023, respectively. The increase and decrease in the liability in 2024 and 2023 were primarily the result of updating the lapse and mortality assumptions used to measure the liability for future policy benefits. The Company also updated the underlying market data used to determine the current discount rate resulting in changes to the discount rate assumption used to measure the net liability for future policy benefits. The following tables provide the balances of and changes in the Company’s liability for future policy benefits, including the deferred profit liability related to the longevity business, for its Financial Solutions business, which primarily consists of longevity reinsurance, asset-intensive products, primarily annuities and financial reinsurance for the years ended December 31, 2024 and 2023 (dollars in millions): For the year ended December 31, 2024: U.S. and Latin America – Financial Solutions Canada – Financial Solutions Europe, Middle East and Africa – Financial Solutions Asia Pacific – Financial Solutions Present Value of Expected Net Premiums Beginning of year balance at original discount rate $ 1,455 $ 3,184 $ 54,832 $ 2,057 Effect of changes in cash flow assumptions 12 — (93) 1 Effect of actual variances from expected experience 73 (7) 1,081 (2) Adjusted balance, beginning of year 1,540 3,177 55,820 2,056 Issuances (1) 2,807 5,346 21,381 7,995 Interest accrual (2) 45 131 1,947 29 Net premiums collected (3) (3,046) (4,752) (5,846) (7,100) Derecognition (4) — — — — Foreign currency translation — (288) (1,942) (222) Ending balance at original discount rate 1,346 3,614 71,360 2,758 Effect of changes in discount rate assumptions (254) (187) (8,636) (294) Balance, end of period $ 1,092 $ 3,427 $ 62,724 $ 2,464 Present Value of Expected Future Policy Benefits Beginning of year balance at original discount rate $ 6,843 $ 3,210 $ 60,938 $ 8,019 Effect of changes in cash flow assumptions 20 — (90) 10 Effect of actual variances from expected experience 67 (7) 1,081 (9) Adjusted balance, beginning of year 6,930 3,203 61,929 8,020 Issuances (1) 2,934 5,372 21,381 7,995 Interest accrual (2) 382 276 2,169 191 Benefit payments (5) (757) (423) (5,114) (460) Derecognition (4) — — — — Foreign currency translation — (494) (2,075) (1,120) Ending balance at original discount rate 9,489 7,934 78,290 14,626 Effect of changes in discount rate assumptions (651) 5 (9,531) (1,880) Balance, end of period $ 8,838 $ 7,939 $ 68,759 $ 12,746 Cumulative amount of fair value hedging adjustments (7) — — — Liability for future policy benefits $ 7,739 $ 4,512 $ 6,035 $ 10,282 Less: reinsurance recoverable (1,373) — — — Net liability for future policy benefits $ 6,366 $ 4,512 $ 6,035 $ 10,282 Weighted-average duration of the liability (in years) 8 13 10 14 Weighted-average interest accretion rate 4.0 % 4.5 % 3.1 % 1.5 % Weighted-average current discount rate 5.6 % 4.7 % 5.2 % 3.1 % (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.

Unpaid Claims and Claim Expense

Unpaid Claims and Claim Expense Short Duration Contracts	12 Months Ended
	Dec. 31, 2024
Insurance [Abstract]
Short-Duration Insurance and Deposit Contracts [Text Block]	UNPAID CLAIMS AND CLAIM EXPENSE – SHORT DURATION CONTRACTS Liabilities for Unpaid Claims and Claim Expense The Company uses several actuarial methods to compute incurred-but-not reported liabilities. These methods use historical claim reporting patterns to develop a triangle of reported claim amounts. The claim triangle is then used to develop the ultimate claims amount and the incurred-but-not reported liabilities. Expected claim methods use exposure data such as premiums to develop the ultimate claim amount. The final method blends the estimates from the development and the expected claim methods. There were no significant changes in methodologies during 2024. The following tables provide information on incurred and paid claims development, net of retrocession, for short-duration reinsurance contracts for the Company’s U.S. and Latin America and Asia Pacific Traditional segments, which primarily relate to group life and health (including disability) business. The short-duration business for the Company’s other segments is immaterial. Liabilities for claims and claims adjustment expenses, net of reinsurance, equals total incurred claims less cumulative paid claims plus outstanding liabilities prior to 2015. The Company provides reinsurance on large quota share transactions. It is common industry practice for cedants to provide loss information on a bulk basis without comprehensive claim details. Additionally, a claim under aggregate stop loss coverage may be the result of thousands of claims, but the Company only pays the excess amount.

Fair Value Measurement See Note 13 – “Fair Value of Assets and Liabilities” for information about fair value measurement of assets and liabilities, except for market risk benefits. Market risk benefits are classified within Level 3 on the fair value hierarchy. The fair value of market risk benefits is monitored through the use of attribution reports to quantify the effect of underlying sources of fair value change, including capital market inputs based on policyholder account values, interest rates and short-term and long-term implied volatility from period to period. D uring the years ended December 31, 2024 and 2023, there were no material changes made to the inputs in the market risk benefit calculations, and nonfinancial assumptions were unchanged.

Reinsurance

Reinsurance Disclosures [Abstract]
Reinsurance	REINSURANCE Ceded Reinsurance In the normal course of business, the Company seeks to limit its exposure to loss on any single insured and to recover a portion of benefits paid by ceding reinsurance to other insurance or reinsurance companies under excess coverage and coinsurance contracts. During the third quarter of 2024, the Company increased its per life retention limit from $8 million to $30 million effective January 1, 2025, and began notifying the Company’s retrocessionaires of the increased per life retention limit and the Company’s intention to recapture the risk ceded to the retrocessionaire in the future. The increased retention limit and updated recapture assumption resulted in a future policy benefits remeasurement loss of $136 million recognized in the third quarter of 2024. Claims in excess of this retention amount are retroceded to retrocessionaires; however, the Company remains fully liable to the ceding company for the entire amount of risk it assumes. In certain limited situations the Company has retained more than its retention limit per individual policy. The Company enters into agreements with other reinsurers to mitigate the residual risk related to the over-retained policies. Additionally, due to some lower face amount reinsurance coverage provided by the Company in addition to individual life, such as group life, disability and health, under certain circumstances, the Company could potentially incur net claims totaling more than its retention limit per individual life. Retrocession reinsurance treaties do not relieve the Company from its obligations to the ceding companies. Failure of retrocessionaires to honor their obligations could result in losses to the Company. The Company regularly evaluates the financial condition of the insurance and reinsurance companies from which it assumes and to which it cedes reinsurance. Allowances would be established for amounts deemed uncollectible. At December 31, 2024 and 2023, no allowances were deemed necessary. Retrocessions are arranged through the Company’s retrocession pools for amounts in excess of the Company’s retention limit. As of December 31, 2024, all rated retrocession pool participants followed by the A.M. Best Company were rated “B++ (good)” or better. The Company verifies retrocession pool participants’ ratings on a quarterly basis. For a majority of the retrocessionaires in the pool that were not rated, security in the form of letters of credit or trust assets has been posted. In addition, the Company performs annual financial reviews of its retrocessionaires to evaluate financial stability and performance. In addition to its third party retrocessionaires, various RGA reinsurance subsidiaries retrocede amounts in excess of their retention to affiliated subsidiaries. Ruby Reinsurance Company (Ruby Re), a Missouri-domiciled life reinsurance company to reinsure U.S. asset-intensive business was launched with the Company as a sponsor. The Company, which is not an investor in Ruby Re, does not consolidate the entity. During 2024, the Company completed two coinsurance funds withheld transactions under which it retroceded $608 million of existing liabilities associated with asset-intensive business to Ruby Re. As of December 31, 2024, the Company has a ceded reinsurance recoverable from Ruby Re of approximately $2.8 billion. Excluding amounts retroceded to Ruby Re, three major reinsurance companies account for approximately 42% of reinsurance ceded receivables and other as of December 31, 2024. As of December 31, 2024 and 2023, $4 million and $10 million of claims recoverable were in excess of 90 days past due, respectively. Also included in the total reinsurance ceded receivables and other is a deposit asset on reinsurance of $2.8 billion and $3.1 billion as of December 31, 2024 and 2023, respectively. The effect of reinsurance on net premiums is as follows (dollars in millions): Years ended December 31, 2024 2023 2022 Direct insurance $ 2,919 $ 1,477 $ 26 Reinsurance assumed 15,573 14,281 13,830 Reinsurance ceded (649) (673) (778) Net premiums $ 17,843 $ 15,085 $ 13,078 The effect of reinsurance on claims and other policy benefits and future policy benefits remeasurement gains and losses is as follows (dollars in millions): Years ended December 31, 2024 2023 2022 Direct insurance $ 3,257 $ 1,577 $ 73 Reinsurance assumed 13,997 12,912 12,867 Reinsurance ceded (383) (679) (667) Net claims and other policy benefits and future policy benefits remeasurement gains and losses $ 16,871 $ 13,810 $ 12,273 The effect of reinsurance on life reinsurance in force is shown in the following schedule (dollars in millions): Direct Assumed Ceded Net Assumed/Net % December 31, 2024 $ 863 $ 3,878,640 $ 71,887 $ 3,807,616 101.9 % December 31, 2023 924 3,704,061 69,242 3,635,743 101.9 % December 31, 2022 1,027 3,400,735 151,569 3,250,193 104.6 Funds Withheld Certain of the Company’s retrocession agreements, including those with Ruby Re, are on a modco or funds withheld basis. While the economic benefits of the funds withheld assets are passed on to the assuming company, the Company retains legal ownership of the assets within the funds withheld account and established a funds withheld liability. Net investment income related to the funds withheld assets is reported in other reinsurance expense and net realized gains (losses) related to the assets are reported net of the amount that is passed on to the assuming company. The following assets were held in support of the Company’s funds withheld arrangements and are reported in the line items shown in the consolidated balance sheets as of December 31, 2024 and 2023 (dollars in millions): For the years ended December 31, 2024 2023 Fixed maturity securities available-for-sale $ 2,615 $ 2,442 Equity securities 2 2 Mortgage loans 451 451 Funds withheld at interest 1,466 1,545 Real estate joint ventures 54 35 Short-term investments and cash and cash equivalents 89 30 Accrued investment income 31 28 Net other assets — 1 Net assets $ 4,708 $ 4,534 Certain assets are reported at amortized cost while the fair value of those assets is reflected in the funds withheld payable. The Company had a $5,017 million and $4,483 million funds withheld payable, net of an embedded derivative asset of $160 million and $206 million as of December 31, 2024 and 2023, respectively. Assumed Reinsurance At December 31, 2024 and 2023, respectively, the Company provided approximately $32.2 billion and $28.3 billion of financial reinsurance, as measured by pre-tax statutory surplus, risk based capital and other financial reinsurance structures, to other insurance companies under financial reinsurance or capital solutions transactions to assist ceding companies in meeting applicable regulatory requirements. Generally, such financial reinsurance is provided by the Company committing cash or assuming insurance liabilities, which are collateralized by future profits on the reinsured business. The Company earns a fee based on the amount of net outstanding financial reinsurance. Reinsurance treaties, whether facultative or automatic, may provide for recapture rights on the part of the ceding company. Recapture rights permit the ceding company to reassume all, or a portion of, the risk formerly ceded to the reinsurer after an agreed-upon period of time, generally 10 years, or in some cases due to changes in the financial condition or ratings of the reinsurer. Recapture of business previously ceded does not affect premiums ceded prior to the recapture of such business but would reduce premiums in subsequent periods. Additionally, some reinsurance treaties give the ceding company the right to require the Company to place assets in trust for their benefit to support the ceding company’s statutory reserve credits, in the event of a downgrade of the Company’s credit ratings and or other statutory measure to specified levels, generally non-investment grade levels, or if minimum levels of financial condition are not maintained. As of December 31, 2024, neither the Company nor its subsidiaries have been required to post additional collateral or have had a reinsurance treaty recaptured as a result of credit downgrade or defined statutory measure decline. Certain reinsurance treaties require the reinsurer to place assets in trust to collateralize the reinsurer’s obligation to the ceding company. Assets placed in trust continue to be owned by the Company, but their use is restricted based on the terms of the trust agreement. Securities with an amortized cost of $3.1 billion and $3.5 billion were held in trust for the benefit of the Company’s subsidiaries to satisfy collateral requirements for reinsurance business at December 31, 2024 and 2023, respectively. Additionally, securities with an amortized cost of $47.1 billion and $32.8 billion as of December 31, 2024 and 2023, respectively, were held in trust to satisfy collateral requirements under certain third-party reinsurance treaties. Under certain conditions, the Company may be obligated to move reinsurance from one subsidiary to another subsidiary, post additional collateral or make payments under a given reinsurance treaty. These conditions include change in control or ratings of the subsidiary, insolvency, nonperformance under a reinsurance treaty, or loss of license or other regulatory authorization of such subsidiary. If the Company was ever required to move reinsurance from one subsidiary to another subsidiary, the risk to the Company on a consolidated basis under the reinsurance treaties would not change; however, additional collateral may need to be posted or additional capital may be required due to the change in jurisdiction of the subsidiary reinsuring the business, which could lead to a strain on liquidity.

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 years ended December 31, 2024 and 2023 (dollars in millions) : Corporate ABS CMBS Total For the year ended December 31, 2024: Balance, beginning of period $ 62 $ 12 $ 1 $ 75 Credit losses recognized on securities for which credit losses were not previously recorded 56 — — 56 Reductions for securities sold during the period (30) — — (30) Additional increases or decreases for credit losses on securities that had an allowance recorded in a previous period (7) 3 — (4) Write-offs recognized against the allowance — — — — Foreign currency translation 1 — — 1 Balance, end of period $ 82 $ 15 $ 1 $ 98 Corporate ABS CMBS Total For the year ended December 31, 2023: Balance, beginning of period $ 27 $ 10 $ — $ 37 Credit losses recognized on securities for which credit losses were not previously recorded 51 — 1 52 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 — 2 — 2 Write-offs recognized against the allowance (6) — — (6) Foreign currency translation — — — — Balance, end of period $ 62 $ 12 $ 1 $ 75 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 6,401 and 5,788 fixed maturity securities for which both the estimated fair value had declined and remained below amortized cost and an allowance for credit loss has not been recorded as of December 31, 2024 and 2023 (dollars in millions). These investments are presented by class and grade of security, as well as the length of time the related fair value has continuously remained below amortized cost.

However, unforeseen facts and circumstances may cause the Company to sell fixed maturity securities in the ordinary course of managing its portfolio to meet certain diversification, credit quality and liquidity guidelines. Changes in unrealized losses are primarily driven by changes in risk-free interest rates and credit spreads. Net Investment Income Major categories of net investment income consist of the following (dollars in millions): For the years ended December 31, 2024 2023 2022 Fixed maturity securities available-for-sale $ 3,541 $ 2,753 $ 2,305 Equity securities 6 6 6 Mortgage loans 401 324 298 Policy loans 56 54 54 Funds withheld at interest 341 317 253 Limited partnerships and real estate joint ventures 96 181 331 Short-term investments and cash and cash equivalents 182 99 29 Other invested assets (11) 21 12 Investment income 4,612 3,755 3,288 Investment expense (196) (164) (127) Net investment income $ 4,416 $ 3,591 $ 3,161 As of December 31, 2024, the Company held non-income producing securities with amortized costs, net of allowances, of $144 million and estimated fair values of $159 million. As of December 31, 2023, the Company held non-income producing securities with amortized costs, net of allowances, of $88 million and estimated fair values of $46 million. Generally, securities are non-income producing when principal or interest is not paid primarily as a result of bankruptcies or credit defaults.

Pledged invested assets are included in the condensed consolidated balance sheets. Invested assets received as collateral are held in separate custodial accounts and are not recorded on the Company’s condensed consolidated balance sheets. Subject to certain constraints, the Company is permitted by contract to sell or repledge collateral it receives; however, as of December 31, 2024 and 2023, none of the collateral received had been sold or repledged. The Company also holds invested assets on deposit to meet regulatory requirements and holds assets in trust to satisfy collateral requirements under derivative transactions and certain third-party reinsurance treaties. The following table includes invested assets on deposit, invested assets pledged and received as collateral, assets in trust held to satisfy collateral requirements and FHLB common stock restricted as to sale as of December 31, 2024 and 2023 (dollars in millions): 2024 2023 Amortized Estimated Amortized Estimated Invested assets on deposit (regulatory deposits) $ 10 $ 8 $ 12 $ 9 Invested assets pledged as collateral 1,200 1,046 572 517 Invested assets received as collateral n/a 2,233 n/a 1,827 Assets in trust held to satisfy collateral requirements 47,162 44,473 32,758 30,359 FHLB common stock restricted as to sale 71 71 63 63 Securities Lending and Repurchase/Reverse Repurchase Agreements The following table provides the estimated fair value of securities relating to securities lending and repurchase/reverse repurchase agreements as of December 31, 2024 and 2023 (dollars in millions): 2024 2023 Securities Loaned, Pledged, or Sold (1) Securities Borrowed or Collateral Received from Counterparties (2) Cash Collateral Received from Counterparties (3) Securities Loaned, Pledged, or Sold (1) Securities Borrowed or Collateral Received from Counterparties (2) Cash Collateral Received from Counterparties (3) Securities lending transactions $ 836 $ 1,093 $ — $ 732 $ 1,013 $ — Repurchase/reverse repurchase transactions 1,781 688 982 1,333 517 820 (1) Securities loaned or pledged through securities lending transactions or sold to counterparties through repurchase transactions are included within fixed maturity securities. Collateral associated with certain securities lending transactions is not included within this table as the collateral pledged to the counterparty is the right to reinsurance treaty cash flows. Certain securities lending transactions do not require collateral. (2) Securities borrowed or received as collateral through securities lending transactions or purchased from counterparties through reverse repurchase transactions are not reflected on the condensed consolidated balance sheets. (3) A payable for the cash received by the Company is included within other liabilities.

The total recorded investment before allowance for credit losses for the modified loans was $124 million as of December 31, 2024. During 2023, the company modified ten mortgage loans providing interest only payments and maturity extensions, two of which were paid in full as of December 31, 2023. The total recorded investment before allowance for credit losses for the remaining modified loans was $92 million as of December 31, 2023. During 2022, the company modified three mortgage loans to interest only payments, one of which was paid in full as of December 31, 2022. During 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 $67 million. The Company had one mortgage loan in the amount of $6 million on nonaccrual status as of December 31, 2024. The Company had one mortgage loan in the amount of $7 million that was on nonaccrual status as of December 31, 2023. During 2024, the Company converted four mortgage loans totaling $46 million to owned properties. Additionally, the Company reclassified one property in the amount of $21 million, that was previously held for sale, to held for use. During 2023, the Company converted three mortgage loans tota lin g $62 million at the time of foreclosure to owned properties as a result of foreclosures. The Company did not acquire any impaired mortgage loans during 2024, 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 December 31, 2024, $3.1 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 December 31, 2024 and 2023 are as follows (dollars in millions): 2024 2023 Limited partnerships – equity method $ 1,067 $ 925 Limited partnerships – fair value 966 856 Limited partnerships – cost method 64 71 Real estate joint ventures 970 783 Total limited partnerships and real estate joint ventures $ 3,067 $ 2,635 Other Invested Assets Other invested assets include lifetime mortgages, derivative contracts and FHLB common stock.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	DERIVATIVE INSTRUMENTS Accounting for Derivative Instruments and Hedging Activities See Note 2 – “Significant Accounting Policies and Pronouncements” for a detailed discussion of the accounting treatment for derivative instruments, including embedded derivatives. See Note 13 – “Fair Value of Assets and Liabilities” for additional disclosures related to the fair value hierarchy for derivative instruments, including embedded derivatives. Types of Derivatives Used by the Company Interest Rate Derivatives Interest rate swaps are used by the Company primarily to reduce market risks from changes in interest rates, to alter interest rate exposure arising from mismatches between assets and liabilities (duration mismatches) and to manage the risk of cash flows of liabilities that are variable based on a benchmark rate. With an interest rate swap, the Company agrees with another party to exchange, at specified intervals, the difference between two rates, which can be either fixed-rate or floating-rate interest amounts, tied to an agreed-upon notional principal amount. These transactions are executed pursuant to master agreements that provide for a single net payment or individual gross payments at each due date. Interest rate options include swaptions that are used by the Company to hedge interest rate risk associated with the Company’s long-term liabilities and invested assets. A swaption is an option to enter a swap with a forward starting effective date. The Company pays a premium for purchased swaptions. Total return swaps are used by the Company to exchange, at specified intervals, the difference between the economic risk and calculated rate of return of an asset or a market index and a benchmark interest rate, calculated by reference to an agreed notional amount. No cash is exchanged at the outset of the contract. Cash is paid and received over the life of the contract based on the terms of the swap. These transactions are entered into pursuant to master agreements that provide for a single net payment to be made by the counterparty at each due date. Total return swaps are used by the Company to reduce market risks from changes in interest rates and to alter interest rate exposure arising from mismatches between assets and liabilities (duration mismatches). Interest rate futures are used primarily to hedge minimum guarantees embedded in certain variable annuity products reinsured by the Company. With exchange-traded interest rate futures transactions, the Company agrees to purchase or sell a specified number of contracts, the value of which is determined by different classes of interest rate securities. The Company posts variation margin on a daily basis in an amount equal to the difference between the daily estimated fair values of those contracts. The Company enters into exchange-traded interest rate futures with regulated futures commission merchants that are members of the exchange. Forward bond purchase commitments are used by the Company to hedge against the variability in the anticipated cash flows required to purchase securities. With forward bond purchase commitments, the forward price is agreed upon at the time of the contract and payment for such contract is made at the future specified settlement date of the securities. Foreign Currency Derivatives Foreign currency swaps are used by the Company to reduce the risk from fluctuations in foreign currency exchange rates associated with its assets and liabilities denominated in foreign currencies. With a foreign currency swap transaction, the Company agrees with another party to exchange, at specified intervals, the difference between one currency and another at a forward exchange rate calculated by reference to an agreed upon principal amount. The principal amount of each currency is exchanged at the termination of the currency swap by each party. Foreign currency forwards are used by the Company to reduce the risk from fluctuations in foreign currency exchange rates associated with its assets and liabilities denominated in foreign currencies. With a foreign currency forward transaction, the Company agrees with another party to deliver a specified amount of an identified currency at a specified future date. The price is agreed upon at the time of the contract and payment for such a contract is made in a different currency at the specified future date. Foreign currency options are used by the Company to reduce the risk from fluctuations in foreign currency exchange rates associated with its assets and liabilities denominated in foreign currencies. With a foreign currency option transaction, the Company purchases an option contract that gives it the right, but not the obligation, to exchange a specified amount of one currency for a specified amount of a different currency on or before a specific date. The contracts may also be net settled in cash, based on differentials in the foreign currency exchange rate and the strike price. Equity Derivatives Equity index options are used by the Company primarily to hedge minimum guarantees embedded in certain variable annuity products and as well as indexed universal life products. To hedge against adverse changes in equity indices, the Company buys put and sells index options. The contracts are net settled in cash based on differentials in the indices at the time of exercise and the strike price. Equity futures are used primarily to economically hedge liabilities embedded in certain variable annuity products. With exchange-traded equity futures transactions, the Company agrees to purchase or sell a specified number of contracts, the value of which is determined by the relevant stock indices. The Company posts variation margin on a daily basis in an amount equal to the difference between the daily estimated fair values of those contracts. The Company enters into exchange-traded futures with regulated futures commission merchants that are members of the exchange. Credit Derivatives The Company sells protection under single name credit default swaps and credit default swap index tranches, as well as other credit derivatives, to diversify its credit risk exposure in certain portfolios and, in combination with purchasing securities, to replicate characteristics of similar investments based on the credit quality and term of the credit default swap. Credit default triggers for indexed reference entities and single name reference entities are defined in the contracts. The Company’s maximum exposure to credit loss equals the notional value for credit default swaps. In the event of default of a referencing entity, the Company is typically required to pay the protection holder the full notional value less a recovery amount determined at auction. Other Derivatives The Company entered into a financial solutions transaction structured as a derivative (“other swaps”) and an offsetting non-payment insurance contract, also accounted for as a derivative, to support capital relief solutions for customers with credit risk to various reference entities. The Company’s maximum exposure to credit loss equals the notional value of the derivative. In the event of default of a referencing entity, the Company is typically required to pay the protection holder the full notional value less a recovery amount up to a contractual detachment point from the non-payment insurance. Consumer price index (“CPI”) swaps are used by the Company primarily to economically hedge liabilities embedded in certain insurance products where value is directly affected by changes in a designated benchmark consumer price index. With a CPI swap transaction, the Company agrees with another party to exchange the actual amount of inflation realized over a specified period of time for a fixed amount of inflation determined at inception. These transactions are executed pursuant to master agreements that provide for a single net payment or individual gross payments to be made by the counterparty at each due date. Most of these swaps will require a single payment to be made by one counterparty at the maturity date of the swap. The Company sells fee-based synthetic guaranteed investment contracts (“GICs”) to retirement plans that include investment-only, stable value contracts. The assets are owned by the trustees of such plans, who invest the assets under the terms of investment guidelines to which the Company agrees. The contracts contain a guarantee of a minimum rate of return on participant balances supported by the underlying assets, and a guarantee of liquidity to meet certain participant-initiated plan cash flow requirements. These contracts are reported as derivatives and recorded at fair value. The Company has certain embedded derivatives that are required to be separated from their host contracts and reported as derivatives. Host contracts include reinsurance treaties structured on a modco or funds withheld basis. Additionally, the Company reinsures insurance products with benefits that are considered embedded derivatives. The changes in fair values of embedded derivatives on insurance products described below relate to changes in the fair value associated with capital market and other related assumptions. Summary of Derivative Positions Freestanding derivatives, except for other swaps, are included in other invested assets or other liabilities, at fair value.

The gain or loss on the hedged item attributable to a change in interest rates or foreign currency and the offsetting gain or loss on the related interest rate or foreign currency swaps for the years ended December 31, 2024, 2023 and 2022 were as follows (dollars in millions): Derivative Type Hedged Item Investment Related Claims and Other Policy Interest Credited Derivatives Hedged Items Derivatives Hedged Items Derivatives Hedged Items For the Year Ended December 31, 2024: Foreign currency swaps Foreign-denominated fixed maturity securities $ 2 $ (4) $ — $ — $ — $ — Interest rate swaps Future policy benefits — — (13) 7 — — Interest rate swaps Interest-sensitive contract liabilities — — — — (18) 12 For the Year Ended December 31, 2023: Foreign currency swaps Foreign-denominated fixed maturity securities (2) (2) — — — — For the Year Ended December 31, 2022: Foreign currency swaps Foreign-denominated fixed maturity securities (1) 7 — — — — 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 (dollars in millions): Hedged Item Carrying Amount of Cumulative Fair Value Hedging Adjustments Included in the Carrying Amount of Hedged Assets / (Liabilities) Discontinued Fair Value Hedge Adjustments Included in the Cumulative Adjustments December 31, December 31, December 31, December 31, December 31, December 31, Foreign-denominated fixed maturity securities $ — $ 89 n/a n/a n/a n/a Future policy benefits (508) — 7 — — — Interest-sensitive contract liabilities (1,111) (25) 11 (1) — 1 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 floating rate assets are converted to fixed rate assets; (iii) forward bond purchase commitments; and (iv) certain foreign currency swaps, in which the cash flows of assets are denominated in different currencies, commonly referred to as cross-currency swaps. The following table presents the cash flow hedge components of AOCI, before income taxes, and where the gain or loss related to cash flow hedges is recognized on the consolidated income statement classification for the years ended December 31, 2024, 2023 and 2022 (dollars in millions): Amounts Included in AOCI Balance December 31, 2021 $ (22) Gains (losses), net deferred in other comprehensive income (loss) (192) Amounts reclassified to net investment income 8 Amounts reclassified to interest expense 1 Balance December 31, 2022 (205) Gains (losses), net deferred in other comprehensive income (loss) (26) Amounts reclassified to net investment income 23 Amounts reclassified to interest expense (10) Balance December 31, 2023 (218) Gains (losses), net deferred in other comprehensive income (loss) (328) Amounts reclassified to net investment income 62 Amounts reclassified to interest expense (11) Balance December 31, 2024 $ (495) As of December 31, 2024, approximately $74 million of before-tax deferred net losses on derivative instruments recorded in AOCI are expected to be reclassified to net investment income during the next twelve months. For the same time period, approximately $7 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 consolidated statements of income for the years ended December 31, 2024, 2023 and 2022 (dollars in millions): Derivative Type Gains (Losses) Deferred in OCI Gains (Losses) Reclassified into Income from AOCI For the year ended December 31, 2024: Net Investment Income Interest Expense Interest rate $ (180) $ (11) $ 11 Foreign currency (148) (51) — Total $ (328) $ (62) $ 11 For the year ended December 31, 2023: Interest rate $ 18 $ (7) $ 10 Foreign currency (44) (16) — Total $ (26) $ (23) $ 10 For the year ended December 31, 2022: Interest rate $ (187) $ — $ (1) Foreign currency (5) (8) — Total $ (192) $ (8) $ (1) For the years ended December 31, 2024, 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 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 years ended December 31, 2024, 2023 and 2022 (dollars in millions): Derivative Gains (Losses) Deferred in OCI For the years ended December 31, Derivative Type 2024 2023 2022 Foreign currency forwards $ 130 $ (18) $ 73 Total $ 130 $ (18) $ 73 The cumulative foreign currency translation gain recorded in AOCI related to these hedges was $313 million a nd $183 million as of December 31, 2024 and 2023, respectively. If a hedged foreign operation was sold or substantially liquidated, the amounts in AOCI would be reclassified to the 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-qualifying derivatives, including embedded derivatives, on the Company’s consolidated statements of income for the years ended December 31, 2024, 2023 and 2022 is as follows (dollars in millions): Gains (Losses) for the years ended December 31, Type of Non-qualifying Derivative Income Statement 2024 2023 2022 Interest rate swaps Investment related gains (losses), net $ (49) $ (15) $ (131) Interest rate options Investment related gains (losses), net (6) (33) 3 Total return swaps Investment related gains (losses), net (7) 14 21 Interest rate futures Investment related gains (losses), net 2 1 6 Foreign currency swaps Investment related gains (losses), net 29 17 21 Foreign currency forwards Investment related gains (losses), net (167) (98) (93) Foreign currency options Investment related gains (losses), net (7) — — Equity options Investment related gains (losses), net (5) (28) 14 Equity futures Investment related gains (losses), net (28) (31) 22 Credit default swaps Investment related gains (losses), net 15 42 (66) CPI swaps Investment related gains (losses), net (4) 6 31 Subtotal (227) (125) (172) Embedded derivatives in: Modco or funds withheld arrangements Investment related gains (losses), net 116 (163) (173) Indexed products Interest credited (22) 17 98 Total non-qualifying derivatives $ (133) $ (271) $ (247) The Company’s utilization of a credit valuation adjustment did not have a material effect on the change in fair value of embedded derivatives for the years ended December 31, 2024, 2023 and 2022. 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 as of December 31, 2024 and 2023 (dollars in millions): 2024 2023 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 (2) Weighted (3) AAA/AA/A Single name credit default swaps $ (5) $ 410 17.5 $ 2 $ 420 18.1 BBB Single name credit default swaps 3 150 2.3 4 165 2.8 Credit default swaps referencing indices — 2,086 5.1 (1) 880 5.0 Subtotal 3 2,236 4.9 3 1,045 4.7 BB Single name credit default swaps — 5 1.5 (1) 10 2.2 B Single name credit default swaps — 10 1.2 — — 0.0 Total $ (2) $ 2,661 6.8 $ 4 $ 1,475 8.5 (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 freestanding derivatives are subject to enforceable master netting arrangements and reported as a net asset or liability in the consolidated balance sheets. The Company nets all derivatives that are subject to such arrangements. The Company has elected to include all freestanding 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. See “Embedded Derivatives” above for information regarding the Company’s bifurcated embedded derivatives. The following table provides information relating to the netting of the Company’s derivative instruments as of December 31, 2024 and December 31, 2023 (dollars in millions): Gross Amounts Recognized Gross Amounts Net Amounts Financial Instruments/Collateral (1) Net Amount December 31, 2024: Derivative assets $ 187 $ (64) $ 123 $ (123) $ — Derivative liabilities 550 (64) 486 (486) — December 31, 2023: Derivative assets $ 154 $ (57) $ 97 $ (97) $ — Derivative liabilities 254 (57) 197 (197) — (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 December 31, 2024, the Company had credit exposure of $15 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. Additionally, the Company is required to pledge initial margin for certain OTC-bilateral derivative transactions. 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 of Assets and Liabilities	FAIR VALUE OF ASSETS AND LIABILITIES 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. 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 December 31, 2024 and 2023 are summarized below (dollars in millions): December 31, 2024: Fair Value Measurements Using: Total Level 1 Level 2 Level 3 Assets: (1) Fixed maturity securities available-for-sale: Corporate $ 50,991 $ — $ 44,137 $ 6,854 Canadian government 5,016 — 5,016 — Japanese government 4,445 — 4,445 — ABS 5,040 — 3,254 1,786 CMBS 2,267 — 2,254 13 RMBS 1,317 — 1,317 — U.S. government 2,464 2,379 80 5 State and political subdivisions 693 — 693 — Other foreign government 5,384 — 5,354 30 Total fixed maturity securities available-for-sale 77,617 2,379 66,550 8,688 Equity securities 155 67 — 88 Funds withheld at interest – embedded derivatives (215) — — (215) Funds withheld at interest 56 — — 56 Cash equivalents 2,055 2,053 2 — Short-term investments 313 175 127 11 Other invested assets: Derivatives 121 — 121 — Other 17 — 17 — Total other invested assets 138 — 138 — Other assets – derivatives 2 — — 2 Total $ 80,121 $ 4,674 $ 66,817 $ 8,630 Liabilities: Interest-sensitive contract liabilities – embedded derivatives $ 435 $ — $ — $ 435 Other liabilities: Funds withheld at interest – embedded derivatives (160) — — (160) Derivatives 486 — 484 2 Total $ 761 $ — $ 484 $ 277 (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, 2023, the fair value of such investments was $856 million. The Company may utilize information from third parties, such as pricing services and brokers, to assist in determining the fair value for certain assets and liabilities; however, management is ultimately responsible for all fair values presented in the Company’s financial statements. This includes responsibility for monitoring the fair value process, ensuring objective and reliable valuation practices and pricing of assets and liabilities, and approving changes to valuation methodologies and pricing sources. The selection of the valuation technique(s) to apply considers the definition of an exit price and the nature of the asset or liability being valued and significant expertise and judgment is required. The Company performs initial and ongoing analysis and review of the various techniques utilized in determining fair value to ensure that they are appropriate and consistently applied, and that the various assumptions are reasonable. The Company analyzes and reviews the information and prices received from third parties to ensure that the prices represent a reasonable estimate of the fair value and to monitor controls around pricing, which includes quantitative and qualitative analysis and is overseen by the Company’s investment and accounting personnel. Examples of procedures performed include, but are not limited to, review of pricing trends, comparison of a sample of executed prices of securities sold to the fair value estimates, comparison of fair value estimates to management’s knowledge of the current market, and ongoing confirmation that third party pricing services use, wherever possible, market-based parameters for valuation. In addition, the Company utilizes both internal and external cash flow models to analyze the reasonableness of fair values utilizing credit spread and other market assumptions, where appropriate. As a result of the analysis, if the Company determines there is a more appropriate fair value based upon the available market data, the price received from the third party is adjusted accordingly. The Company also determines if the inputs used in estimated fair values received from pricing services are observable by assessing whether these inputs can be corroborated by observable market data. For assets and liabilities reported at fair value, the Company utilizes, when available, fair values based on quoted prices in active markets that are regularly and readily obtainable. Generally, these are very liquid investments, and the valuation does not require management judgment. When quoted prices in active markets are not available, fair value is based on market valuation techniques, market comparable pricing and the income approach. The use of different techniques, assumptions and inputs may have a material effect on the estimated fair values of the Company’s securities holdings. For the periods presented, the application of market standard valuation techniques applied to similar assets and liabilities has been consistent. The methods and assumptions the Company uses to estimate the fair value of assets and liabilities measured at fair value on a recurring basis are summarized below. Fixed Maturity Securities – The fair values of the Company’s publicly-traded fixed maturity securities are generally based on prices obtained from independent pricing services. Prices from pricing services are sourced from multiple vendors, and a vendor hierarchy is maintained by asset type based on historical pricing experience and vendor expertise. The Company generally receives prices from multiple pricing services for each security, but ultimately uses the price from the vendor that is highest in the hierarchy for the respective asset type. To validate reasonableness, prices are periodically reviewed as explained above. Consistent with the fair value hierarchy described above, securities with quotes from pricing services are generally reflected within Level 2, as they are primarily based on observable pricing for similar assets and/or other market observable inputs. If the pricing information received from third party pricing services is not reflective of market activity or other inputs observable in the market, the Company may challenge the price through a formal process with the pricing service. If the Company ultimately concludes that pricing information received from the independent pricing service is not reflective of fair value, non-binding broker quotes are used, if available. If the Company concludes that the values from both pricing services and brokers are not reflective of fair value, an internally developed valuation may be prepared; however, this occurs infrequently. Internally developed valuations or non-binding broker quotes are also used to determine fair value in circumstances where vendor pricing is not available. These valuations may use significant unobservable inputs, which reflect the Company’s assumptions about the inputs that market participants would use in pricing the asset. Observable market data may not be available in certain circumstances, such as market illiquidity and credit events related to the security. Internally developed valuations and non-binding broker quotes are generally based on significant unobservable inputs and are reflected as Level 3 in the valuation hierarchy. The inputs used in the valuation of corporate and government securities include, but are not limited to, standard market observable inputs that are derived from, or corroborated by, market observable data including market yield curve, duration, call provisions, observable prices and spreads for similar publicly traded or privately placed issues that incorporate the credit quality and industry sector of the issuer. For internal pricing of private placements and structured securities, valuation is based primarily on matrix pricing or other similar techniques using standard market inputs including spreads for actively traded securities, spreads off benchmark yields, expected prepayment speeds and volumes, current and forecasted loss severity, rating, weighted average coupon, weighted average maturity, average delinquency rates, geographic region, debt service coverage ratios and issuance-specific information including, but not limited to: collateral type, payment terms of the underlying assets, payment priority within the tranche, structure of the security, transaction performance and vintage of loans. When observable inputs are not available, the market standard valuation techniques for determining the estimated fair value of certain types of securities that trade infrequently, and therefore have little or no price transparency, 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, such as market illiquidity. Other significant unobservable inputs used in the fair value measurement of the Company’s private debt investments include a multiple of earnings before interest, taxes, depreciation and amortization (“EBITDA”). These unobservable inputs can be based in large part on management judgment or estimation and cannot be supported by reference to market activity. Even though unobservable, these inputs are based on assumptions deemed appropriate given the circumstances and are believed to be consistent with what other market participants would use when pricing such securities. Equity Securities – Equity securities consist principally of common and preferred stock of publicly and privately traded companies. The fair values of publicly traded equity securities are primarily based on quoted market prices in active markets and are classified within Level 1 in the fair value hierarchy. Non-binding broker quotes and internally developed evaluations for equity securities are generally based on significant unobservable inputs and are reflected as Level 3 in the fair value hierarchy. Embedded Derivatives – The fair value of embedded derivative liabilities, including those calculated by third parties, are monitored through the use of attribution reports to quantify the effect of underlying sources of fair value change, including capital market inputs based on policyholder account values, interest rates and short-term and long-term implied volatilities, from period to period. Actuarial assumptions are based on experience studies performed internally in combination with available industry information and are reviewed on a periodic basis, at least annually. For embedded derivative liabilities associated with underlying insurance products in reinsurance treaties, the Company utilizes a discounted cash flow model, which includes an estimate of future equity option purchases and an adjustment for a CVA. To validate the reasonableness of the resulting fair value, the Company’s actuaries perform reviews and analytical procedures on the results. The capital market inputs to the model are generally observable. The valuation also requires certain significant inputs, which are generally not observable and accordingly, the valuation is considered Level 3 in the fair value hierarchy. The fair value of embedded derivatives associated with funds withheld reinsurance treaties is determined based upon a total return swap technique with reference to the fair value of the investments held by the ceding company that support the Company’s funds withheld at interest asset with an adjustment for a CVA. The fair value of the underlying assets is generally based on a variety of sources and pricing methodologies chosen by the ceding company, which are not transparent to the Company and may include significant unobservable inputs. Additionally, some of the valuations also require certain significant inputs, which are generally not observable. Therefore, the valuation of the embedded derivative assets and liabilities associated with these funds withheld reinsurance treaties are considered Level 3 in the fair value hierarchy. Where those funds withheld reinsurance agreements are ceded by the Company, the same approach is taken to valuing the embedded derivatives associated with the funds withheld at interest liability. Credit Valuation Adjustment – The Company bases its CVA on corporate Option-adjusted spread (“OAS”) indexes and market conditions adjusted for the Company’s specific factors. The input assumptions are a combination of externally derived and publicly available information, corporate OAS indexes, market inputs and internally developed data based on Company specific investments by rating category. Funds Withheld at Interest – Funds withheld at interest, elected at fair value on a limited basis, include assets where inputs are not observable in the market and are considered Level 3 in the fair value hierarchy. Cash Equivalents and Short-Term Investments – Cash equivalents and short-term investments include money market instruments and other highly liquid debt instruments which are generally valued using unadjusted quoted prices in active markets that are accessible for identical assets and are primarily classified as Level 1. The fair value of certain other cash equivalents and short-term investments, such as bonds with original maturities twelve months or less, are based upon other market observable data and are typically classified as Level 2. However, certain short-term investments may incorporate significant unobservable inputs resulting in a Level 3 classification. Various time deposits, certificates of deposit and sweeps carried as cash equivalents or short-term investments are not measured at estimated fair value and therefore are excluded from the tables presented. Other – FVO contractholder-directed investments supporting unit-linked variable annuity type liabilities consist of fixed maturity securities. The fair value of the fixed maturity contractholder-directed securities is determined on a basis consistent with the methodologies described above for fixed maturity securities and are classified within Level 2 of the hierarchy. Derivative Assets and Derivative Liabilities – Derivative instruments utilized by the Company are typically classified within Level 2 on the fair value hierarchy. These derivatives are principally valued using an income approach. Valuations of interest rate contracts are based on present value techniques, which utilize significant inputs that may include the swap yield curve, Secured Overnight Financing Rate (“SOFR”) basis curves, Overnight Index Swaps curves, and repurchase rates. Valuations of foreign currency contracts are based on present value techniques, which utilize significant inputs that may include the swap yield curve, currency spot rates, and cross currency basis curves. Valuations of credit contracts are based on present value techniques, which utilize significant inputs that may include the swap yield curve, credit curves, and recovery rates. Valuations of equity market contracts are based on present value techniques, which utilize significant inputs that may include the swap yield curve, spot equity index levels, and dividend yield curves. Valuations of equity market contracts, option-based, are based on option pricing models, which utilize significant inputs that may include the swap yield curve, spot equity index levels, dividend yield curves, and equity volatility. Other swaps relate to a financial solutions transaction structured as a derivative. These derivatives are valued using a credit default swap model utilizing inputs that are both observable and unobservable and are thus classified as Level 3 on the fair value hierarchy. 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 December 31, 2024 and 2023 (dollars in millions): Estimated Fair Value Valuation Unobservable Range (Weighted Average) 2024 2023 Technique Input 2024 2023 Assets: Corporate $ 99 $ 91 Market comparable securities Liquidity premium 2% 0-2% (1%) EBITDA Multiple 6.7x-11.0x (9.7x) 6.0x-8.5x (7.1x) ABS 564 268 Market comparable securities Liquidity premium 0-10% (3%) 0-18% (2%) U.S. government — 7 Market comparable Liquidity premium — 0-1% (1%) Equity securities 33 31 Market comparable Liquidity premium 4% 4% EBITDA Multiple 7.4x-12.8x (10.9x) 8.4x-12.3x (10.1x) Funds withheld at interest – embedded derivatives 22 (50) Total return swap Mortality 0-100% (3%) 0-100% (3%) Lapse 0-35% (18%) 0-35% (18%) Withdrawal 0-10% (4%) 0-5% (4%) CVA 0-5% (0%) 0-5% (0%) Crediting rate 1-4% (2%) 1-4% (2%) Other assets – derivatives 2 — Credit default swap Credit spread 0-1% (0%) — Probability of default 0-8% (0%) — Liabilities: Interest-sensitive contract liabilities – embedded derivatives – indexed products 435 415 Discounted cash flow Mortality 0-100% (3%) 0-100% (3%) Lapse 0-35% (17%) 0-35% (17%) Withdrawal 0-10% (4%) 0-5% (4%) Option budget 1-4% (2%) 1-4% (2%) Other liabilities – derivatives 2 — Credit default swap Credit spread 0-1% (0%) — Probability of default 0-8% (0%) — 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. The Company had Level 3 other swap assets and liabilities that on a gross and net basis were not material for the year ended December 31, 2024. The reconciliations for all assets and liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3) are as follows (dollars in millions): For the year ended December 31, 2024: Fixed maturity securities – available-for-sale Funds withheld at interest –embedded derivatives, net (1) Funds Interest-sensitive contract Corporate Foreign govt Structured securities U.S. and local govt Equity securities Cash equivalents Short-term investments Fair value, beginning of period $ 4,933 $ 35 $ 1,425 $ 26 $ 70 $ — $ 2 $ (171) $ 54 $ (415) Total gains/losses (realized/unrealized) Included in earnings, net: Net investment income 13 — 4 — — — — — 5 — Investment related gains (losses), net (58) — (1) — (5) — (1) — — — Interest credited — — — — — — — 116 — (22) Included in other comprehensive income (loss) (26) (5) — — — — — — (1) — Purchases (2) 3,142 — 752 — 24 — 14 — 2 (98) Sales (2) (344) — (65) — (1) — (1) — — — Settlements (2) (754) — (396) (2) — — (1) — (4) 100 Transfers into Level 3 2 — 117 2 — — — — — — Transfers out of Level 3 (54) — (37) (21) — — (2) — — — Fair value, end of period $ 6,854 $ 30 $ 1,799 $ 5 $ 88 $ — $ 11 $ (55) $ 56 $ (435) Total gains/losses (realized/unrealized) recorded for the period relating to those Level 3 assets and liabilities that were still held at the end of the period Included in earnings, net: Net investment income $ 8 $ — $ 3 $ — $ — $ — $ — $ — $ 5 $ — Investment related gains (losses), net (55) — (3) — (6) — (1) 116 — — Interest credited — — — — — — — — — (123) Included in other comprehensive income (loss) (24) (5) 1 — — — — — (1) — (1) Funds withheld at interest – embedded derivative assets and liabilities are presented net for purposes of the rollforward.

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. For the years ended December 31, 2024 and 2023, 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 December 31, 2024 and 2023 (dollars in millions). 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.

(2) Carrying values and estimated fair values presented herein include a reinsurance recoverable of $2.0 billion and $2.2 billion as of December 31, 2024 and 2023, respectively. (3) Carrying values and estimated fair values presented herein exclude FABN carrying values of $3.2 billion and $1.3 billion as of December 31, 2024 and 2023, respectively, and estimated fair values of $3.2 billion and $1.2 billion as of December 31, 2024 and 2023, respectively. Mortgage Loans – The fair value of mortgage loans is estimated by discounting cash flows, both principal and interest, using current interest rates for mortgage loans with similar credit ratings and similar remaining maturities. As such, inputs include current treasury yields and spreads, which are based on the credit rating and average life of the loan, corresponding to the market spreads. The valuation of mortgage loans is considered Level 3 in the fair value hierarchy. Policy Loans – Policy loans typically carry an interest rate that is adjusted annually based on an observable market index and therefore carrying value approximates fair value. The valuation of policy loans is considered Level 2 in the fair value hierarchy. Funds Withheld at Interest – The carrying value of funds withheld at interest approximates fair value except where the funds withheld are specifically identified in the agreement. When funds withheld are specifically identified in the agreement, the fair value is based on the fair value of the underlying assets that are held by the ceding company. A variety of sources and pricing methodologies, which are not transparent to the Company and may include significant unobservable inputs, are used to value the securities that are held in distinct portfolios, therefore the valuation of these funds withheld assets and liabilities are considered Level 3 in the fair value hierarchy. Limited Partnerships – The fair value of limited partnerships accounted for using the cost method, considered Level 3 in the fair value hierarchy, is estimated by internally developed valuation techniques. Cash and Cash Equivalents and Short-term Investments – The carrying values of cash and cash equivalents and short-term investments approximate fair values due to the short-term maturities of these instruments and are considered Level 1 in the fair value hierarchy. Other Invested Assets – This primarily includes lifetime mortgages, FHLB common stock, and cash collateral. The fair value of the Company’s lifetime mortgage loan portfolio, considered Level 3 in the fair value hierarchy, is estimated by discounting cash flows, both principal and interest, using a risk-free rate plus an illiquidity premium. The cash flow analysis considers future expenses, changes in property prices, and actuarial analysis of borrower behavior, mortality and morbidity. The fair value of the Company’s common stock investment in the FHLB is considered to be the carrying value and it is considered Level 2 in the fair value hierarchy. The fair value of the Company’s cash collateral is considered to be the carrying value and considered to be Level 1 in the fair value hierarchy. Accrued Investment Income – The carrying value for accrued investment income approximates fair value as there are no adjustments made to the carrying value. This is considered Level 2 in the fair value hierarchy. Interest-Sensitive Contract Liabilities – The carrying and fair values of interest-sensitive contract liabilities reflected in the table above exclude contracts with significant mortality risk. The fair value of the Company’s interest-sensitive contract liabilities utilizes a market standard technique with both capital market inputs and policyholder behavior assumptions, as well as cash values adjusted for recapture fees. The capital market inputs to the model, such as interest rates, are generally observable. Policyholder behavior assumptions are generally not observable and may require use of signific

Income Tax Disclosure [Abstract]
Income Tax	INCOME TAX Pre-tax income for the years ended December 31, 2024, 2023 and 2022 consists of the following (dollars in millions): 2024 2023 2022 Pre-tax income – U.S. $ 572 $ 898 $ 294 Pre-tax income – foreign 408 262 424 Total pre-tax income $ 980 $ 1,160 $ 718 The provision for income tax expense for the years ended December 31, 2024, 2023 and 2022 consists of the following (dollars in millions): 2024 2023 2022 Current income tax expense (benefit): U.S. $ 150 $ (18) $ 10 Foreign 167 58 120 Total current 317 40 130 Deferred income tax expense (benefit): U.S. (129) 236 32 Foreign 68 (25) 35 Total deferred (61) 211 67 Total provision for income taxes $ 256 $ 251 $ 197 The effective tax rate for 2024 was higher than the U.S. statutory rate of 21% primarily due to income earned in non-U.S. jurisdictions and the tax expense related to a legal entity restructuring which were partially offset by the release of valuation allowances in non-U.S. jurisdictions and benefits related to return to provision adjustments. The effective tax rate for 2023 was higher than the U.S. statutory rate of 21% primarily as a result of income earned in jurisdictions with tax rates higher than the U.S. and changes to the valuation allowance which were partially offset with foreign tax credits. The Organization for Economic Cooperation and Development (“OECD”) developed Model Global Anti-Base Erosion (“GloBE”) rules under Pillar II establishing a Global Minimum Tax to ensure multinational enterprises with consolidated revenue of more than EUR750 Million pay at least an effective tax rate of 15% on income arising in each jurisdiction in which they operate. As of December 31, 2024, many of the jurisdictions in which the Company operates enacted Pillar II legislation into domestic law with an effective date of January 1, 2024, while others enacted domestic law with an effective date of January 1, 2025. The Company recorded a tax expense of $5 million related to Pillar II. The Inflation Reduction Act of 2022 (“the Act”) was enacted in 2022. 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 over $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 2024. 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. Bermuda enacted the Corporate Income Tax Act of 2023 on December 27, 2023. The Bermuda regime establishes a statutory tax rate of 15%, applicable to companies with annual revenue of EUR750 million or more. The tax regime is effective for fiscal years beginning on or after January 1, 2025. The Company maintains deferred taxes and associated valuation allowances on the applicable subsidiaries’ financial statements. The Company’s effective tax rate differed from the U.S. federal income tax statutory rate of 21% as a result of the following for the years ended December 31, 2024, 2023 and 2022 (dollars in millions): 2024 2023 2022 Tax provision at U.S. statutory rate $ 206 $ 244 $ 150 Increase (decrease) in income taxes resulting from: Tax rate differences on income in other jurisdictions 44 14 35 Differences in tax basis in foreign jurisdictions (18) 4 10 Deferred tax valuation allowance (5) 15 (4) Amounts related to uncertain tax positions 2 (2) 3 Compensation 1 2 (2) Corporate rate changes (4) — 7 GILTI, net of credits 14 — 21 Subpart F for non-full inclusion companies 26 28 60 Foreign tax credits (5) (42) (72) Return to provision and amended adjustments (17) (9) (13) Pillar II 5 — — Effects of tax law changes and restructuring 9 — — Other, net (2) (3) 2 Total provision for income taxes $ 256 $ 251 $ 197 Effective tax rate (1) 26.3 % 21.8 % 27.3 % (1) The Company rounds amounts in the financial statements to millions and calculates the effective tax rate from the underlying whole dollar amounts. Thus, certain amounts may not recalculate based on the numbers due to rounding. Total income taxes for the years ended December 31, 2024, 2023 and 2022 were as follows (dollars in millions): 2024 2023 2022 Provision for income taxes $ 256 $ 251 $ 197 Income tax from OCI and additional paid-in-capital: Net unrealized investment gains (losses) recognized in OCI (176) 449 (2,542) Liability for future policyholder benefits 586 (161) 2,224 Market risk benefits — (3) 5 Foreign currency translation 32 22 35 Unrealized pension and postretirement 2 (2) 7 Total income taxes provided $ 700 $ 556 $ (74) The tax effects of temporary differences that give rise to significant portions of the deferred income tax assets and liabilities as of December 31, 2024 and 2023 are presented in the following tables (dollars in millions): 2024 2023 Deferred income tax assets: Nondeductible accruals $ 102 $ 96 Net operating loss carryforward 846 272 Capital loss carryforwards 92 15 Tax credit carryforward 220 108 Invested assets 1,407 1,092 Anticipated future foreign tax credit 442 267 Subtotal 3,109 1,850 Valuation allowance (678) (567) Total deferred income tax assets 2,431 1,283 Deferred income tax liabilities: Deferred acquisition costs 931 833 Policy reserves and other reinsurance liabilities 3,428 1,789 Outside basis difference foreign subsidiaries — 152 Foreign currency translation 190 179 Other 3 80 Total deferred income tax liabilities 4,552 3,033 Net deferred income tax liabilities $ 2,121 $ 1,750 Balance sheet presentation of net deferred income tax liabilities: Included in other assets $ 78 $ 112 Included in deferred income taxes 2,199 1,862 Net deferred income tax liabilities $ 2,121 $ 1,750 As of December 31, 2024, the valuation allowance against deferred tax assets was $678 million. The increase in the valuation allowance was primarily related to the deferred tax associated with mark to market losses included in AOCI. The Company reduced the deferred tax asset to the amount more likely than not to be realized. Other increases to the valuation allowance related to losses in foreign subsidiaries that do not have a history of income. These increases were partially offset by releases in certain jurisdictions where the deferred tax assets are more likely than not to be utilized. As of December 31, 2023, the valuation allowance against deferred tax assets was $567 million. During 2023, the Company established a $303 million deferred tax asset and a corresponding valuation allowance related to the enactment of the Bermuda tax regime. Other increases to the valuation allowance were related to losses in foreign subsidiaries that do not have a history of income. These increases were partially offset by releases in certain jurisdictions where the deferred tax assets are more likely than not to be utilized. The earnings of substantially all of the Company's foreign subsidiaries have been permanently reinvested in foreign operations. U.S. tax law generally eliminates U.S. federal income taxes on dividends from foreign subsidiaries, the Company does not expect to incur material income taxes if these funds were repatriated. During 2024, 2023 and 2022, the Company received federal and foreign income tax refunds of approximately $12 million, $13 million and $3 million, respectively. The Company made cash income tax payments of approximately $90 million, $311 million and $131 million, in 2024, 2023 and 2022, respectively. The following table presents consolidated net operating loss carryforwards (“NOL”) as of December 31, 2024 (dollars in millions): 2024 NOL with no expiration and with no valuation allowance $ 2,845 NOL with a full valuation allowance 591 NOL with no expiration and a partial valuation allowance 463 NOL with expiration date of 2034 and no valuation allowance — Total net operating loss carryforwards $ 3,899 These net operating losses, other than the net operating losses for which there is a valuation allowance, are expected to be utilized in the normal course of business during the period allowed for carryforwards and in any event, are not expected to be lost, due to the application of tax planning strategies that management would utilize. As of December 31, 2024, the Company had foreign tax credit carryforwards of $220 million related to the U.S. and Ireland. The earliest year of expiration on the U.S. foreign tax credits is 2033. The U.S. credits are expected to be utilized in the ordinary course of business to offset U.S. tax liabilities. The Ireland foreign tax credit of $23 million has a full valuation allowance. The Company files income tax returns in the U.S. federal jurisdiction and various state and foreign jurisdictions. U.S. audit periods remain open for refund claims for 2018-2020 and for years beginning after 2020. The Company is also subject to audit by state and foreign jurisdictions for years 2019 and thereafter, with a few exceptions. As of December 31, 2024, the Company’s total amount of unrecognized tax benefits is $33 million all of which would affect the effective tax rate, if recognized. Management believes it is reasonably possible that the unrecognized tax benefit could decrease by up to $6 million over the next 12 months if statues expire. A reconciliation of the beginning and ending amount of unrecognized tax benefits for the years ended December 31, 2024, 2023 and 2022 is as follows (dollars in millions): Total Unrecognized Tax Benefits 2024 2023 2022 Beginning balance, January 1 $ 33 $ 36 $ 34 Additions for tax positions of prior years 2 9 3 Reductions for tax positions of prior years (9) (15) (4) Additions for tax positions of current year 7 3 3 Ending balance, December 31 $ 33 $ 33 $ 36 The Company recognized minimal interest expense (benefit) associated with uncertain tax positions in 2024, 2023 and 2022. As of December 31, 2024 and 2023, the Company had $3 million and $3 million of accrued interest related to unrecognized tax benefits. There are no penalties accrued as of December 31, 2024 or 2023.

Retirement Benefits [Abstract]
Defined Benefit Plan	EMPLOYEE BENEFIT PLANS Certain subsidiaries of the Company are sponsors or administrators of both qualified and non-qualified defined benefit pension plans (“Pension Plans”). The largest of these plans is a non-contributory qualified defined benefit pension plan sponsored by RGA Reinsurance Company (“RGA Reinsurance”) that covers U.S. employees. The benefits under the Pension Plans are generally based on years of service and compensation levels. The qualified defined benefit pension plan and some of the non-qualified defined benefit pension plans are closed to new employees. The Company also provides select health care and life insurance benefits for certain retired employees. The health care benefits are provided through a self-insured welfare benefit plan. Employees become eligible for these benefits if they meet minimum age and service requirements. The retiree’s cost for health care benefits varies depending upon the credited years of service. New employees hired in the U.S. are not eligible for retiree health care benefits. Virtually all retirees, or their beneficiaries, contribute a portion of the total cost of postretirement health benefits. Over funded and underfunded plans are recognized in other assets and other liabilities, respectively. A December 31 measurement date is used for all of the defined benefit and postretirement plans.

The Company has not determined whether, and to what extent, contributions may be made to the qualified pension plans in 2025. During 2025, the Company expects to contribute $4 million and $3 million to its non-qualified pension plans and other benefit plans, respectively. The following benefit payments, which reflect expected future service as appropriate, are expected to be paid (dollars in millions): Pension Benefits Other Benefits 2025 $ 20 $ 3 2026 18 3 2027 18 4 2028 20 4 2029 19 4 2030-2034 111 20 Assumptions The weighted average assumptions used to determine the benefit obligation and net periodic benefit cost were as follows: Pension Benefits Other Benefits 2024 2023 2022 2024 2023 2022 Benefit obligation Discount rate 5.33 % 4.78 % 5.00 % 5.47 % 4.79 % 4.99 % Rate of compensation increase 4.55 % 4.71 % 4.96 % n/a n/a n/a Net periodic benefit cost Discount rate 4.78 % 5.01 % 2.65 % 4.79 % 4.99 % 2.76 % Expected long-term rate of return on plan assets 7.00 % 7.00 % 6.50 % n/a n/a n/a Rate of compensation increase 4.71 % 4.97 % 4.75 % n/a n/a n/a The expected rate of return on plan assets is based on anticipated performance of the various asset sectors in which the plan invests, weighted by target allocation percentages. Anticipated future performance is based on long-term historical returns of the plan assets by sector, adjusted for the long-term expectations on the performance of the markets. While the precise expected return derived using this approach may fluctuate from year to year, the policy is to hold this long-term assumption constant as long as it remains within reasonable tolerance from the derived rate. The assumed health care cost trend rates used in measuring the accumulated non-pension postretirement benefit obligation were as follows: As of December 31, 2024 2023 Health care cost trend rates assumed for next year 6.90 % 6.50 % Ultimate cost trend rate 4.50 % 4.50 % Year ultimate trend is reached 2032 2028 Plan Assets The Company’s overall investment strategy is to allocate 100% of investments for long-term growth. Target allocations of U.S. qualified pension plan assets are determined with the objective of maximizing returns and minimizing volatility of net assets through adequate asset diversification and partial liability immunization. Adjustments are made to target allocations based on the Company’s assessment of the effect of economic factors and market conditions. The target allocations for plan assets were 75.5% equity and alternative securities and 24.5% debt securities for 2024 and 2023. The Company’s plan assets are invested in mutual funds and exchange traded funds. The mutual funds and exchange traded funds include holdings of S&P 500 securities, large-cap securities, mid-cap securities, small-cap securities, international securities, corporate debt securities, U.S. and other government securities, mortgage-related securities and cash. Equity and debt securities are exposed to various risks, such as interest rate risk, credit risk and overall market volatility. Due to the level of risk associated with certain investment securities, changes in the values of investment securities will occur and any change would affect the amounts reported in the financial statements. The fair values of the Company’s qualified pension plan assets as of December 31, 2024 and 2023 are summarized below (dollars in millions): December 31, 2024 Fair Value Measurement Using: Total Level 1 Level 2 Level 3 Mutual Funds (1) $ 131 $ 131 $ — $ — Exchange Traded Funds (2) 65 65 — — Cash — — — — Total $ 196 $ 196 $ — $ — (1) Mutual funds were invested 18% in U.S. equity funds, 53% in U.S. fixed income funds, 15% in non-U.S. equity funds and 14% in other.

See Note 13 – “Fair Value of Asset and Liabilities” for additional information on the fair value hierarchy. Savings and Investment Plans Certain subsidiaries of RGA also sponsor savings and investment plans under which a portion of employee contributions are matched. Subsidiary contributions to these plans were $30 million, $27 million and $23 million in 2024, 2023 and 2022, respectively.

Statutory Basis [Abstract]
Financial Condition and Net Income on a Statutory Basis - Significant Subsidiaries	FINANCIAL CONDITION AND NET INCOME ON A STATUTORY BASIS – SIGNIFICANT SUBSIDIARIES The domestic and foreign insurance subsidiaries of RGA prepare their statutory financial statements in conformity with accounting practices prescribed or permitted by the applicable state insurance department or local regulatory authority, which may vary materially from statements prepared in accordance with GAAP. Prescribed statutory accounting practices in the U.S. include publications of the National Association of Insurance Commissioners (“NAIC”), as well as state laws, local regulations and general administrative rules. The differences between statutory financial statements and financial statements prepared in accordance with GAAP vary between jurisdictions. The principal differences between GAAP and NAIC are that statutory financial statements do not reflect deferred policy acquisition costs and limit deferred tax assets, life benefit reserves predominately use interest rate and mortality assumptions prescribed by the NAIC and local regulatory agencies, bonds are generally carried at amortized cost and reinsurance assets and liabilities are presented net of reinsurance. Statutory net income and capital and surplus of the Company’s primary operating insurance subsidiaries, determined in accordance with statutory accounting practices prescribed by the applicable state insurance department or local regulatory authority. The amounts below reflect the Company’s best estimate of the statutory capital, surplus and net income for the subsidiaries listed below as of the date the Company files this Annual Report. (dollars in millions): Statutory Capital and Surplus Statutory Net Income (Loss) 2024 2023 2024 2023 2022 RGA Americas Reinsurance Company, Ltd. $ 5,466 $ 4,304 $ 686 $ 657 $ (441) RGA Life and Annuity Insurance Company 3,253 3,206 122 157 5 RGA Reinsurance Company 2,307 2,437 (3) 483 (332) RGA Reinsurance Company (Barbados) Ltd. 2,200 1,621 275 133 (143) RGA Life Reinsurance Company of Canada 1,447 1,303 36 38 (7) RGA International Reinsurance Company Dac 781 718 20 21 44 RGA Worldwide Reinsurance Company, Ltd. 688 641 41 64 8 RGA Reinsurance Company of Australia Limited 445 456 14 52 (67) RGA Global Reinsurance Company, Ltd. 447 561 (43) (22) — Rockwood Reinsurance Company 420 93 104 (883) 90 Each U.S. domestic insurance subsidiary’s state of domicile imposes minimum risk-based capital (“RBC”) requirements that were developed by the NAIC. The formulas for determining the amount of RBC specify various weighting factors that are applied to financial balances or various levels of activity based on the perceived degree of risk. Regulatory compliance is determined by a ratio of total adjusted capital, as defined by the NAIC, to authorized control level RBC, as defined by the NAIC. Companies below specific trigger points or ratios are classified within certain levels, each of which requires specified corrective action. Each of RGA’s U.S. domestic insurance subsidiaries exceeded the minimum RBC requirements for all periods presented herein. These requirements do not represent a significant constraint for the payment of dividends by RGA’s U.S. domestic insurance companies. The licensing orders of the Company’s special purpose companies stipulate a minimum amount of capital required based on the purpose of the entity and the underlying business. These companies are subject to enhanced oversight by the regulator which includes filing detailed plans of operations before commencing operations or making material changes to existing agreements or entering into new agreements. Each of the Company’s Special Purpose Life Reinsurance Captives (“SPLRC”) exceeded the minimum capital requirements for all periods presented herein. The Company’s foreign insurance subsidiaries prepare financial statements in accordance with local regulatory requirements. The regulatory authorities in these foreign jurisdictions establish some form of minimum regulatory capital and surplus requirements. All of the Company’s foreign insurance subsidiaries have regulatory capital and surplus that exceed the local minimum requirements. These requirements do not represent a significant constraint for the payment of dividends by the Company’s foreign insurance companies. The state of domicile of certain of the Company’s SPLRCs follow prescribed accounting practices differing from NAIC statutory accounting practices (“NAIC SAP”) applicable to their statutory financial statements. Specifically, these prescribed practices require that surplus note interest accrued but not approved for payment be reported as a direct reduction of surplus and an addition to the surplus note balance. Under NAIC SAP, surplus note interest is not to be reported until approved for payment and is reported as a reduction of net investment income in the Summary of Operations. In addition, these prescribed practices allow the SPLRC to reflect letters of credit issued for its benefit as an admitted asset and a direct credit to unassigned surplus. Under NAIC SAP, letters of credit issued on behalf of the reporting company are not reported on the balance sheet. A reconciliation of the surplus between NAIC SAP and practices prescribed by the state of domicile is shown below (dollars in millions): December 31, 2024 2023 Prescribed practice – surplus $ 549 $ 340 Prescribed practice – letters of credit (380) (426) Surplus (deficit) – NAIC SAP $ 169 $ (86) RGA Life and Annuity and RGA Reinsurance are subject to Missouri statutory provisions that restrict the payment of dividends. They may not pay dividends in any 12 month period in excess of the greater of the prior year’s statutory net gain from operations or 10% of statutory capital and surplus at the preceding year-end, without regulatory approval. Aurora National is subject to California statutory provisions that are identical to those imposed by Missouri regarding the ability of Aurora National to pay dividends to RGA Reinsurance. The applicable statutory provisions only permit an insurer to pay a shareholder dividend from unassigned surplus. As of January 1, 2024, RGA Reinsurance could pay maximum dividends, without prior approval, of approximately $231 million. Any dividends paid by RGA Reinsurance would be paid to RGA Life and Annuity, its parent company, which in turn has restrictions related to its ability to pay dividends to RGA. The Missouri Department of Commerce and Insurance allows RGA Life and Annuity to pay a dividend to RGA to the extent RGA Life and Annuity received the dividend from its subsidiaries, without limitation related to the level of unassigned surplus. Dividend payments from other subsidiaries are subject to regulations in the jurisdiction of domicile, which are generally based on their earnings and/or capital level. Dividend payments from non-U.S. operations are subject to similar restrictions established by local regulators. The non-U.S. regulatory regimes also commonly limit the dividend payments to the parent to a portion of the prior year’s statutory income, as determined by the local accounting principles. The regulators of the Company’s non-U.S. operations may also limit or prohibit profit repatriations or other transfers of funds to the U.S. if such transfers are deemed to be detrimental to the solvency or financial strength of the non-U.S. operations, or for other reasons. Most of the non-U.S. operating subsidiaries are second tier subsidiaries that are owned by various non-U.S. holding companies. The capital and rating considerations applicable to the first tier subsidiaries may also impact the dividends paid to RGA. There are no regulatory restrictions that limit the payment of dividends by RGA, except those generally applicable to Missouri corporations. Dividends are payable by Missouri corporations only under the circumstances specified in The General and Business Corporation Law of Missouri. RGA would not be permitted to pay common stock dividends if there is any accrued and unpaid interest on its subordinated debentures and its junior subordinated debentures. Furthermore, the ability of RGA to pay dividends is dependent on business conditions, income, cash requirements of the Company, receipt of dividends from its subsidiaries, financial covenant provisions and other relevant factors.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingent Liabilities	COMMITMENTS, CONTINGENCIES AND GUARANTEES Commitments Funding of Investments The Company’s commitments to fund investments as of December 31, 2024 and 2023, are presented in the following table (dollars in millions): 2024 2023 Limited partnerships and real estate joint ventures $ 1,103 $ 1,058 Mortgage loans 81 137 Bank loans and private placements 1,950 810 Lifetime mortgages 103 53 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 current expected credit losses associated with unfunded commitments as of December 31, 2024 and 2023. Funding Agreements Federal Home Loan Bank (“FHLB”) 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 December 31, 2024 and 2023, the Company had $1.3 billion and $1.1 billion, respectively, 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 December 31, 2024 and 2023, the Company had $3.2 billion and $1.3 billion of FABN agreements outstanding, which are included within interest-sensitive contract liabilities. In January 2025, the Company issued additional FABN agreements totaling $600 million. 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 December 31, 2024, 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 December 31, 2024 (dollars in millions): Commitment Period Maximum Potential Obligation 2034 $ 1,243 2035 1,874 2036 2,349 2037 5,100 2038 1,750 2039 8,751 2041 720 2046 3,000 2049 4,750 Support Agreements The Company, the obligor, is a party to a capital maintenance agreement with its subsidiary, RGA Life and Annuity, the beneficiary. Under this agreement, the obligor guarantees for specified periods of time that the beneficiary will meet specified capital and surplus levels. The Company anticipates that in the event this arrangement places demand on it, there will be sufficient liquidity and capital to meet such demand.

On May 13, 2024, the Company issued 5.75% fixed rate Senior Notes due 2034 with a face amount of $650 million, which will be used for general corporate purposes. Capitalized issuance costs were $6 million. On June 8, 2023, the Company issued 6.00% fixed rate Senior Notes due 2033 with a face amount of $400 million, which was used to repay upon maturity the $400 million 4.70% Senior Notes that matured on September 15, 2023. Capitalized issuance costs were $4 million. On March 23, 2023, Chesterfield Reinsurance Company, a subsidiary of RGA, issued 7.125% Surplus Notes due 2043, with a face amount of $500 million. Capitalized issue costs were $6 million. The loan is expected to be repaid over the term of the loan based on available funds and regulatory approval. As of December 31, 2024, the amount outstanding is $450 million. On March 13, 2023, the Company entered into a new syndicated revolving credit facility with a five year term and an overall capacity of $850 million, replacing its existing $850 million syndicated revolving credit facility, which was scheduled to mature in August 2023. The Company may borrow cash and may obtain letters of credit in multiple currencies under this facility. Certain of the Company’s debt agreements contain financial covenant restrictions related to, among others, liens, the issuance and disposition of stock of restricted subsidiaries, minimum requirements of consolidated net worth, maximum ratios of debt to capitalization and change of control provisions. A material ongoing covenant default could require immediate payment of the amount due, including principal, under the various agreements. Additionally, the Company’s debt agreements contain cross-default covenants, which would make outstanding borrowings immediately payable in the event of a material uncured covenant default under any of the agreements, including, but not limited to, non-payment of indebtedness when due for an amount in excess of the amounts set forth in those agreements, bankruptcy proceedings, or any other event that results in the acceleration of the maturity of indebtedness. As of December 31, 2024 and 2023, the Company had $5,081 million and $4,464 million, respectively, in outstanding borrowings under its debt agreements and was in compliance with all covenants under those agreements. As of December 31, 2024 and 2023, the average interest rate on long-term debt outstanding was 5.16% and 5.09%, respectively. The ability of the Company to make debt principal and interest payments depends on the earnings and surplus of subsidiaries, investment earnings on undeployed capital proceeds, and the Company’s ability to raise additional funds. Future principal payments due on long-term debt, excluding discounts, as of December 31, 2024, were as follows (dollars in millions): Calendar Year 2025 2026 2027 2028 2029 Thereafter Long-term debt $ 4 $ 404 $ 4 $ 4 $ 604 $ 4,071 Credit and Committed Facilities The Company has obtained bank letters of credit in favor of various affiliated and unaffiliated insurance companies from which the Company assumes business. These letters of credit represent guarantees of performance under the reinsurance agreements and allow ceding companies to take statutory reserve credits. Certain of these letters of credit contain financial covenant restrictions. At December 31, 2024 and 2023, there were approximately $126 million and $54 million, respectively, of undrawn outstanding bank letters of credit in favor of third parties. Additionally, the Company utilizes letters of credit primarily to secure reserve credits when it retrocedes business to its affiliated subsidiaries. The Company cedes business to its affiliates to help reduce the amount of regulatory capital required in certain jurisdictions such as the U.S. and the UK. As of December 31, 2024 and 2023, $1.1 billion and $728 million, respectively, in undrawn letters of credit from various banks were outstanding, primarily backing reinsurance between the various subsidiaries of the Company. The banks providing letters of credit to the Company are included on the NAIC list of approved banks.

The committed credit facilities have a combined capacity of $950 million while the syndicated revolving credit facility is for $850 million and the remaining letter of credit facilities have a capacity of $1.5 billion. The Company may borrow cash and obtain letters of credit in multiple currencies under its syndicated revolving credit facility. The Company’s subsidiaries, RGA Reinsurance and RGA Americas, maintain a $200 million committed facility to provide contingent capital to RGA Reinsurance and RGA Americas.

Total fees expensed associated with the Company’s letters of credit were $10 million, $6 million and $11 million for the years ended December 31, 2024, 2023 and 2022, respectively, and are included in policy acquisition costs and other insurance expenses.

Segment Information

Segment Information	12 Months Ended

Segment Reporting [Abstract]
Segment Information	SEGMENT INFORMATION Segments The Company has nine geographic-based and business-based operational segments including a Corporate and Other segment. Geographic-based operations are further segmented into traditional and financial solutions businesses. The Company’s geographic based segments are U.S. and Latin America; Canada, Europe Middle East and Africa, and Asia Pacific. Traditional reinsurance includes individual and group life and health, disability, long-term care and critical illness reinsurance. Financial Solutions includes asset-intensive reinsurance, longevity reinsurance, stable value products, pension risk transfer transactions and capital solutions products. The Corporate and Other revenues primarily include investment income from unallocated invested assets and service fees. Corporate and Other expenses consist of the offset to capital charges allocated to the operating segments within the policy acquisition costs and other insurance income line item, unallocated corporate overhead and executive costs, interest expense related to debt and service business expenses. Additionally, Corporate and Other includes results from the Company’s Funding Agreement Backed Notes (“FABN”) program. Segment Accounting Policies The accounting policies of the segments are the same as those described in Note 2 – “Significant Accounting Policies and Pronouncements.” 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. In addition, the segments are charged for excess capital utilized above the allocated economic capital basis. This charge is included in policy acquisition costs and other insurance expenses. There are no intersegment reinsurance transactions or revenues, and the Company does not have any material long-lived assets. No individual client generated 10% or more of the Company’s total gross premiums and other revenues on a consolidated basis in 2024, 2023 and 2022. For the purpose of this disclosure, companies that are within the same insurance holding company structure are combined. Financial Measures The Company segment measure of profit or loss is adjusted operating income (loss) before income taxes. Adjusted operating income before income taxes does not equate to “Income (loss) before income taxes” as determined in accordance with U.S. GAAP but is the measure of segment profit or loss used by the Company’s chief operating decision maker to evaluate segment performance and allocate resources and, consistent with authoritative guidance, is the measure of segment performance presented below. Adjusted operating income (loss) before income taxes is calculated as income before income taxes excluding, as applicable: • Substantially all of the effect of net investment related gains and losses; • Changes in the fair value of embedded derivatives; • Changes in the fair value of contracts that provide market risk benefits; • Non-economic losses at contract inception for direct pension risk transfer single premium business (which are amortized into adjusted operating income within claims and other policy benefits over the estimated lives of the contracts); • Any net gain or loss from discontinued operations; • The cumulative effect of any accounting changes; • The impact of certain tax related items; and • Any other items the Company believes are not indicative of the Company’s ongoing operations. The Company’s significant expenses are (1) adjusted claims and other policy benefits which exclude the non-economic losses at contract inception for direct pension risk transfer single premium business, (2) future policy benefits remeasurement gains and losses, (3) adjusted interest credited, which excludes the change in fair value of embedded derivatives associated with equity-indexed annuities and (4) interest expense. The Company’s chief operating decision maker is the President and Chief Executive Officer (“CEO”). The CEO uses segment adjusted operating income before income taxes to allocate resources (including employees and financial and capital resources) for each segment including consideration of future performance. The CEO considers performance on a monthly basis for segment adjusted operating income before income taxes when making decisions about allocating capital, personnel, evaluating market opportunities and future growth. The CEO also uses segment adjusted operating income before income taxes to assess the performance for each segment and for evaluating compensation of certain employees.

Equity Based Compensation

Equity Based Compensation	12 Months Ended

Share-Based Payment Arrangement [Abstract]
Equity Based Compensation	Long-term Incentive Compensation The Company adopted the RGA Flexible Stock Plan in February 1993, as amended, the Flexible Stock Plan for Directors in January 1997, as amended, and the Phantom Stock Plan for Directors in January 1997, as amended (collectively, the “Plans”). The Plans provide for the award of benefits of various types of long-term incentive compensation, including cash and equity based awards. Equity based awards include stock options, stock appreciation rights (“SARs”), restricted stock, performance shares and other equity based awards to key employees, officers, directors and others performing significant services for the benefit of the Company or its subsidiaries. As of December 31, 2024, shares authorized for the granting of benefits under the RGA Flexible Stock Plan, the Flexible Stock Plan for Directors and the Phantom Stock Plan for Directors totaled 16,460,077, 307,500 and 155,000, respectively. The Company uses treasury shares or shares made available from authorized but unissued shares to support the future exercise of options or settlement of awards granted under its Plans. The Company recognized equity based compensation expense of $60 million, $46 million and $45 million in 2024, 2023 and 2022, respectively, related to equity based awards under the Plans, primarily due to performance shares, stock appreciation rights and restricted stock. In general, equity based awards granted under the Plans become exercisable over vesting periods ranging from one to four years. SARs are generally granted with a conversion price equal to the stock’s fair value at the date of grant and expire 10 years after the date of grant. There were no stock options outstanding issued to the Company’s directors under the Flexible Stock Plan during the periods presented. Information with respect to grants under the Plans are as follows. Stock Options and Stock Appreciation Rights The following table presents a summary of options and SARs activity: Number of Options and SARs Weighted-Average Exercise/Conversion Price Aggregate Intrinsic Value (in millions) Outstanding as of December 31, 2023 1,870,582 $ 118.70 Granted 115,394 $ 187.92 Exercised (413,798) $ 107.29 Forfeited (11,785) $ 145.26 Outstanding as of December 31, 2024 1,560,393 $ 126.67 $ 136 Awards exercisable 1,364,619 $ 123.61 $ 123 The intrinsic value of awards exercised was $39 million, $27 million, and $16 million for 2024, 2023 and 2022, respectively. Awards Outstanding Awards Exercisable Range of Exercise Prices Number Outstanding as Weighted-Average Weighted- Number Weighted-Average $90.00 – $109.99 429,937 4.2 $ 99.93 369,545 $ 98.86 $110.00 – $129.99 629,326 5.0 $ 122.74 629,326 $ 122.74 $130.00 – $149.99 270,809 5.9 $ 142.30 211,351 $ 143.42 $150.00 + 230,321 6.1 $ 168.93 154,397 $ 159.30 Totals 1,560,393 5.1 $ 126.67 1,364,619 $ 123.61 The following table presents the weighted-average assumptions used to determine the fair value of SARs granted: For the years ended December 31, 2024 2023 2022 Dividend yield 1.84 % 2.31 % 2.74 % Risk-free rate of return 4.33 % 4.15 % 2.41 % Expected volatility 38.3 % 37.1 % 36.0 % Expected life (in years) 6.0 6.3 6.3 Weighted-average exercise price of stock options granted $ 185.28 $ 138.34 $ 106.53 Weighted-average fair value of stock options granted $ 67.95 $ 47.20 $ 30.55 The Black-Scholes model was used to determine the fair value recognized in the financial statements of SARs that have been granted. The Company used daily historical volatility when calculating the SAR’s value. The benchmark rate is based on observed interest rates for instruments with maturities similar to the expected term of the stock options. Dividend yield is determined based on historical dividend distributions compared to the price of the underlying common stock as of the valuation date and held constant over the life of the stock options. The Company estimated expected life using the historical average years to exercise or cancellation. Performance Shares Performance Shares are units that, if vested, are multiplied by a performance factor to produce a number of final shares that are paid in the Company’s common stock. Each unit represents the right to receive up to two shares of the Company’s common stock, depending on the results of certain performance measures. Compensation expense related to Performance Shares is recognized ratably over the requisite performance period. Restricted Stock Units In general, restricted stock units (“RSUs”) become payable at the end of a three year vesting period. Each RSU, if vested, represents the right to receive one share of Company common stock. RSUs generally do not have a strike price and are included in the Company’s shares outstanding. The following table presents a summary of Performance Units and Restricted Stock Units activity: Performance Units (1) Restricted Stock Units Outstanding as of December 31, 2023 359,551 417,306 Granted 116,883 95,566 Paid (100,158) (102,632) Forfeited (13,814) (15,841) Outstanding as of December 31, 2024 362,462 394,399 (1) Performance Unit amounts above represent the number of Performance Units to be issued at target performance and do not reflect potential increases or decreases that may result from the performance factor. At December 31, 2024, the performance period for the 2022 – 2024 Performance Share grants was completed, but the performance factor had not yet been determined. Included in the above table are 74,536 outstanding Performance Units to which the 2022 – 2024 performance factor will be applied. During 2024, the Company granted 116,883 Performance Shares at a weighted-average fair value per unit of $185.28. As of December 31, 2024, the total compensation cost of non-vested awards not yet recognized in the financial statements was $33 million. It is estimated that these costs will vest over a weighted-average period of 0.5 years. The majority of the awards granted each year under the Plans are made in the first quarter of each year.

Significant Accounting Policies and Pronouncements (Policies)	12 Months Ended

Accounting Policies [Abstract]
Consolidation and Basis of Presentation	Basis of Presentation The consolidated financial statements of the Company have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”). The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosures of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The most significant estimates include those used in determining the following: • Premiums receivable; • Future policy benefits and incurred but not reported claims; • Income taxes; • Valuation of investments, investment allowance for credit losses and investment impairments; • Valuation of embedded derivatives and market risk benefits. Actual results could differ materially from the estimates and assumptions used by management. The accompanying consolidated financial statements include the accounts of RGA and its subsidiaries, all of which are wholly owned, and any variable interest entities where the Company is the primary beneficiary. The Company evaluates variable interest entities in accordance with the general accounting principles for Consolidation . 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. Intercompany balances and transactions have been eliminated. There were no subsequent events that would require disclosure or adjustments to the accompanying consolidated financial statements through the date the consolidated financial statements were issued.
Investments	Investments Fixed Maturity Securities Fixed maturity securities classified as available-for-sale are reported at fair value and are so classified based upon the possibility that such securities could be sold prior to maturity if that action enables the Company to execute its investment philosophy and appropriately match investment results to operating and liquidity needs. Unrealized gains and losses on fixed maturity securities classified as available-for-sale, less applicable deferred income taxes, are recorded in other comprehensive income (loss) (“OCI”). Investment income is recognized as it accrues or is legally due. Realized gains and losses on sales of investments are included in investment related gains (losses), net, as are changes in allowance for credit losses and impairments. The cost of investments sold is primarily determined based upon the specific identification method. Equity Securities Equity securities are carried at fair value and realized and unrealized gains and losses are included in investment related gains (losses), net. Mortgage Loans Mortgage loans are carried at unpaid principal balances, net of any unamortized premium or discount, unamortized balance of loan origination fees and expenses, and allowance for credit losses. Interest income is accrued on the principal amount of the mortgage loan based on its contractual interest rate. Amortization of premiums, discounts, and loan origination fees are recorded using the effective yield method. The Company accrues interest on loans until it is probable the Company will not receive interest, or the loan is 90 days past due. Interest income, amortization of premiums, accretion of discounts, amortization of loan origination fees and prepayment fees are reported in net investment income. Funds Withheld at Interest Funds withheld at interest represent amounts contractually withheld by ceding companies in accordance with reinsurance agreements. For agreements written on a modified coinsurance (“modco”) basis and agreements written on a coinsurance funds withheld basis, assets that support the net statutory reserves or as defined in the treaty, are withheld and legally owned by the ceding company. Interest, recorded in net investment income, accrues to these assets at calculated rates as defined by the treaty terms. Changes in the value of the equity options held within the funds withheld portfolio associated with equity-indexed annuity treaties are reflected in net investment income. Limited Partnerships and Real Estate Joint Ventures Limited partnerships and real estate joint ventures, in which the Company has more than a minor influence over the investee’s operations, are reported using the equity method of accounting. Contributions paid by the Company increase carrying value and distributions received by the Company reduce carrying value. 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. Limited partnerships, in which the Company has a minor ownership interest in or virtually no influence over the investee’s operations, are primarily carried at estimated fair value. If a readily determinable fair value is not available, the Company uses the net asset value ("NAV") per share. Changes in estimated fair value are included in investment related gains (losses), net. Certain other limited partnerships are carried at cost less impairment. Short-Term Investments Short-term investments represent investments with remaining maturities of one year or less, but greater than three months, at the time of acquisition and are stated at estimated fair value or amortized cost, which approximates estimated fair value. Interest on short-term investments is recorded in net investment income. Other Invested Assets In addition to derivative contracts discussed below, other invested assets include Federal Home Loan Bank common stock, unit-linked investments, lifetime mortgages, and real estate held for investment. FHLB common stock is carried at cost. The fair value option (“FVO”) was elected for contractholder-directed investments supporting unit-linked variable annuity type liabilities that do not qualify for presentation and reporting as separate accounts. Changes in estimated fair value of unit-linked investments are included in net investment income. Lifetime mortgages are carried at unpaid principal balances, net of any unamortized premium or discount, unamortized balance of loan origination fees and expenses, and allowance for credit losses. Interest income is accrued on the principal amount of the lifetime mortgage based on its contractual interest rate. Real estate held for investment, including related improvements, is carried at cost less accumulate depreciation. Depreciation is calculated on a straight-line basis over the estimated useful life of the property. The Company’s real estate held for investment is primarily acquired upon foreclosure of mortgage loans and is recorded at estimated fair value at the time of foreclosure. The carrying value of real estate held for investment is adjusted for impairments whenever events or changes in circumstances indicate the carrying amount of the asset may not be recoverable. Such impairment adjustments are recorded in investment related gains (losses), net. Securities Lending and Repurchase/Reverse Repurchase Agreements The Company participates in securities lending programs whereby securities, which are not reflected on the Company’s consolidated balance sheets, are borrowed from third parties. The borrowed securities are used to provide collateral under affiliated reinsurance transactions. The Company is generally required to maintain a minimum of 100% to 110% of the fair value, or par value under certain programs, of the borrowed securities as collateral. The collateral generally consists of securities pledged to the third parties or rights to reinsurance treaty cash flows. If cash flows from the reinsurance treaties are insufficient to maintain the minimum collateral requirement, the Company may substitute cash or securities to meet the requirement. The Company participates in a securities lending program whereby securities, reflected as investments on the Company’s consolidated balance sheets, are loaned to a third party. In return, the Company receives securities from the third party, with an estimated fair value generally equal to 105% of the securities lent. The securities received as collateral are not reflected on the Company’s consolidated balance sheets. The Company participates in repurchase/reverse repurchase programs whereby securities, reflected as investments on the Company’s consolidated balance sheets, are sold to third parties. In return, the Company purchases securities from the third parties. Under the agreements the Company’s value of the securities sold is generally equal to 100% to 108% of the estimated fair value of the securities purchased. The securities purchased under reverse repurchase agreements are not reflected on the Company’s consolidated balance sheets. Securities sold under such transactions may be sold or re-pledged by the transferee. The Company participates in repurchase programs, whereby securities, reflected as investments on the Company’s consolidated balance sheets are sold to a third party. Under these agreements, the Company receives cash in an amount generally equal to 72% to 100% of the estimated fair value of the securities sold at the inception of the transaction, with a simultaneous agreement to repurchase such securities at a future date or on demand in an amount equal to the cash initially received plus interest. The Company monitors the ratio of the cash held to the estimated fair value of the securities sold throughout the duration of the transaction and additional cash or securities are provided or obtained as necessary. Securities sold under such transactions may be sold or re-pledged by the transferee. The obligation to repurchase bonds is reflected in other liabilities. Allowance for Credit Losses and Impairments Fixed Maturity Securities The Company identifies fixed maturity securities that could result in a credit loss by monitoring market events that could impact issuers’ credit ratings, business climates, management changes, litigation, government actions and other similar factors. The Company also monitors late payments, pricing levels, rating agency actions, key financial ratios, financial statements, revenue forecasts and cash flow projections as indicators of credit issues. The Company reviews all securities to determine whether a decline in fair value below amortized cost has resulted from a credit loss and whether an allowance for credit loss should be recognized. In making this determination, the Company considers relevant facts and circumstances including: (1) the reasons for the decline in fair value; (2) the issuer’s financial position and access to capital; and (3) the Company’s intent to sell a security or whether it is more likely than not it will be required to sell the security before the recovery of its amortized cost that, in some cases, may extend to maturity. If the Company intends to sell a security or it is more likely than not that it would be required to sell a security before the recovery of its amortized cost, less any recorded credit loss, it recognizes an impairment loss in investment related gains (losses), net for the difference between amortized cost and fair value. Credit impairments and changes in the allowance for credit losses on fixed maturity securities are reflected in investment related gains (losses), net, while non-credit impairment losses are recognized in other comprehensive income (loss) (“OCI”). The Company estimates the amount of the credit loss component of a fixed maturity security impairment as the difference between amortized cost and the present value of the expected cash flows of the security. The Company excludes accrued interest from the amortized cost and the present value of the expected cash flows of the security. The present value is determined using the best estimate cash flows discounted at the effective interest rate implicit to the security at the date of purchase or the current yield to accrete an asset-backed or floating rate security. The techniques and assumptions for establishing the best estimate cash flows vary depending on the type of security. The asset-backed securities’ cash flow estimates are based on security-specific facts and circumstances that may include collateral characteristics, expectations of delinquency and default rates, loss severity and prepayment speeds and structural support, including subordination and guarantees. The Company writes off uncollectible fixed maturity securities when (1) it has sufficient information to determine that the issuer of the security is insolvent or (2) it has received notice that the issuer of the security has filed for bankruptcy, and the collectability of the asset is expected to be adversely impacted by the bankruptcy. Mortgage Loans Allowance for credit losses on mortgage loans are computed on an expected loss basis using a model that utilizes probability of default and loss given default methods over the lifetime of the loan. Within the reasonable and supportable forecast period (i.e., typically two years), the allowance for credit losses for mortgage loans is established based on several pool-level loan assumptions, defaults and loss severity, loss expectations for loans with similar risk characteristics and industry statistics. These evaluations are revised as conditions change and new information becomes available. The evaluation also includes the impact of expected changes in future macro-economic conditions. The Company reverts to historical loss information for periods beyond which it believes it is able to develop or obtain reasonable and supportable forecasts of future economic conditions. When individual loans no longer have similar credit risk characteristics of the commercial mortgage loan pool, they are removed from the pool and are evaluated individually for an allowance. Any interest accrued or received on the net carrying amount of the impaired loan is included in net investment income or applied to the principal of the loan, depending on the assessment of the collectability of the loan. Mortgage loans deemed to be uncollectible or that have been foreclosed are recorded against the allowance for credit losses and subsequent recoveries, if any, are credited to the allowance for credit losses. Changes in allowance for credit losses are reported in investment related gains (losses), net. The Company may grant a loan modification related to a borrower’s ongoing financial difficulties. Generally, the types of concessions include reduction of the contractual interest rate, extension of the maturity date at an interest rate lower than current market interest rates and/or a reduction of accrued interest. The Company considers the amount, timing and extent of the concession granted in determining any changes in allowance for credit losses recorded in connection with the modification. Through the continuous monitoring process, the Company may have recorded a specific allowance for credit loss prior to when the mortgage loan is modified. Accordingly, the carrying value (after specific allowance for credit loss) before and after modification may not change significantly or may increase if the expected recovery is higher than the pre-modification recovery assessment. Limited Partnerships and Real Estate Joint Ventures The Company considers its limited partnership investments that are carried at cost for impairment when the carrying value of these investments exceeds the fair value. The Company takes into consideration the severity and duration of this excess when deciding if the investment is impaired. For equity method investments (including real estate joint ventures), the Company considers financial and other information provided by the investee, other known information and inherent risks in the underlying investments, as well as future capital commitments, in determining whether an impairment has occurred. When it is determined a limited partnership investment has had a loss in value that is other than temporary, an impairment is recognized. Such an impairment is reported in investment related gains (losses), net.
Policy Loans Receivable	Policy Loans Policy loans are reported at the unpaid principal balance. Interest income on such loans is recorded as earned using the contractually agreed-upon interest rate. These policy loans present no credit risk because the amount of the loan cannot exceed the obligation due the ceding company upon the death of the insured or surrender of the underlying policy.
Derivative Instruments	Derivative Instruments Overview The Company utilizes a variety of derivative instruments including swaps, options, forwards and futures, primarily to manage or hedge interest rate risk, credit risk, inflation risk, foreign currency risk, market volatility and various other market risks associated with its business. The Company does not invest in derivatives for speculative purposes. It is the Company’s policy to enter into derivative contracts primarily with highly rated parties. See Note 12 – “Derivative Instruments” for additional detail on the Company’s derivative positions. Accounting and Financial Statement Presentation of Derivatives Derivatives are carried on the Company’s consolidated balance sheets primarily in other invested assets or other liabilities, at fair value. Certain derivatives are subject to master netting provisions and reported as a net asset or liability. On the date a derivative contract is executed, the Company designates the derivative as (1) a fair value hedge, (2) a cash flow hedge, (3) a net investment hedge in a foreign operation or (4) free standing derivatives held for other risk management purposes, which primarily involve managing asset or liability risks associated with the Company’s reinsurance treaties that do not qualify for hedge accounting. Changes in the fair value of free standing derivative instruments, which do not receive accounting hedge treatment, are primarily reflected in investment related gains (losses), net. Hedge Documentation and Hedge Effectiveness 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 as either: (i) a fair value hedge; (ii) a cash flow hedge; or (iii) a hedge of a net investment in a foreign operation. In this 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 periodically throughout the life of the designated hedging relationship. Under a fair value hedge, changes in the fair value of the hedging derivative are reported within the same line item in the consolidated statements of income as changes in the fair value of the hedged item related to the designated risk being hedged. The fair values of the hedging derivatives are exclusive of any accruals that are separately reported within the consolidated statements of income to match the location of the hedged item. Under a cash flow hedge, changes in the fair value of the hedging derivative measured as effective are reported within AOCI and the deferred gains or losses on the derivative are reclassified into the consolidated statements of income when the Company’s earnings are affected by the variability in cash flows of the hedged item. The fair values of the hedging derivatives are exclusive of any accruals that are separately reported within investment income or interest expense to match the location of the hedged item. In a hedge of a net investment in a foreign operation, changes in the fair value of the hedging derivative that are measured as effective are reported within AOCI consistent with the translation adjustment for the hedged net investment in the foreign operation. 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, the derivative continues to be carried in the consolidated balance sheets at fair value, with changes in fair value recognized in investment related gains (losses), net. The carrying value of the hedged 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. Provided the hedged forecasted transaction occurrence is still probable, the changes in estimated fair value of derivatives recorded in OCI related to discontinued cash flow hedges are released into the consolidated statements of income when the Company’s earnings are affected by the variability in cash flows of the hedged item. 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 in the consolidated balance sheets at its estimated fair value, with changes in estimated fair value recognized currently in investment related gains (losses), net. 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 are recognized immediately in investment related gains (losses), net. In all other situations in which hedge accounting is discontinued, the derivative is carried at its estimated fair value in the consolidated balance sheets, with changes in its estimated fair value recognized in the current period as investment related gains (losses), net. Embedded Derivatives The Company reinsures certain insurance products that contain terms that are deemed to be embedded derivatives. The Company assesses reinsurance contract terms to identify embedded derivatives, which are required to be bifurcated under the general accounting principles for Derivatives and Hedging . If the contract is not reported for in its entirety at fair value and it is determined that the terms of the embedded derivative are not clearly and closely related to the economic characteristics of the host contract, and that a separate instrument with the same terms would qualify as a derivative instrument, the embedded derivative is bifurcated from the host contract and accounted for separately. Reinsurance treaties written on a modco or funds withheld basis are subject to the general accounting principles for Derivatives and Hedging related to embedded derivatives. The Company’s funds withheld at interest assets and liabilities are associated with its reinsurance treaties structured on a modco or funds withheld basis, the majority of which were subject to the general accounting principles for Derivatives and Hedging related to embedded derivatives. The valuation of embedded derivatives is sensitive to the investment credit spread environment. Changes in investment credit spreads are also affected by the application of a credit valuation adjustment (“CVA”). The fair value calculation of an embedded derivative in an asset position utilizes a CVA based on the ceding company’s retrocessionaire’s credit risk. Conversely, the fair value calculation of an embedded derivative in a liability position utilizes a CVA based on the Company’s credit risk. Generally, an increase in investment credit spreads, ignoring changes in the CVA, will have a negative impact on the fair value of the embedded derivative (decrease in income). The fair value of the embedded derivative assets and liabilities are included in the funds withheld at interest and funds withheld payable, respectively. The embedded derivatives are included in funds withheld at interest and funds withheld payable on the consolidated balance sheets, and the change in the fair value of the embedded derivatives is recorded in investment related gains (losses), net. The Company has entered into various financial reinsurance treaties on a funds withheld and modco basis. These treaties do not transfer significant insurance risk and are recorded on a deposit method of accounting with the Company earning a net fee. As a result of the experience refund provisions contained in these treaties, the value of the embedded derivatives in these contracts is currently considered immaterial. The Company monitors the performance of these treaties on a quarterly basis. Significant adverse performance or losses on these treaties may result in a loss associated with the embedded derivative.
Fair Value Measurements	Fair Value Measurements General accounting principles for Fair Value Measurements and Disclosures define fair value, establish a framework for measuring fair value, establish a fair value hierarchy based on the inputs used to measure fair value and enhance disclosure requirements for fair value measurements. In compliance with these principles, the Company has categorized its assets and liabilities, based on the priority of the inputs to the valuation technique, into a three level hierarchy or separately for assets measured using the NAV. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1), the second highest priority to quoted prices in markets that are not active or inputs that are observable either directly or indirectly (Level 2) and the lowest priority to unobservable inputs (Level 3). If the inputs used to measure fair value fall within different levels of the hierarchy, the category level is based on the lowest priority level input that is significant to the fair value measurement of the asset or liability. See Note 13 – “Fair Value of Assets and Liabilities” for further details on the Company’s assets and liabilities recorded at fair value.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents include cash on deposit and highly liquid debt instruments purchased with an original maturity of three months or less.
Deferred Policy Acquisition Costs	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. Eligible deferred policy acquisition costs related to short-duration contracts are capitalized and amortized in proportion to premium. Amortization of DAC is included in policy acquisition costs and other insurance expenses.
Other Reinsurance Balances	Other Reinsurance Balances The Company assumes and retrocedes financial reinsurance contracts that do not expose it to a reasonable possibility of loss from insurance risk. These contracts are reported as deposits and are included in other reinsurance assets/liabilities. The amount of revenue reported in other revenues on these contracts represents fees and the cost of insurance under the terms of the reinsurance agreement. Assets and liabilities are reported on a net or gross basis, depending on the specific details within each treaty. Reinsurance agreements reported on a net basis, where a legal right of offset exists, are generally included in other reinsurance balances on the consolidated balance sheets. Balances resulting from the assumption and/or subsequent transfer of benefits and obligations resulting from cash flows related to variable annuities have also been classified as other reinsurance balance assets and/or liabilities. Other reinsurance assets are included in premiums receivable and other reinsurance balances while other reinsurance liabilities are included in other reinsurance balances.
Value of Distribution Agreements and Customer Relationships Acquired	Value of Distribution Agreements and Customer Relationships Acquired Value of distribution agreements (“VODA”) is reported in other assets and represents the present value of future profits associated with the expected future business derived from the distribution agreements. 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. VODA is amortized over a useful life of 15 years and VOCRA is also amortized over a 15 year period in proportion to expected revenues generated, with amortization included in policy acquisition costs and other insurance expenses. Each year the Company reviews VODA and VOCRA to determine the recoverability of these balances. VODA and VOCRA totaled approximately $0 million and $6 million as of December 31, 2024 and 2023, respectively. Other Acquired Intangible Assets Other acquired intangibles are reported in other assets and primarily represent intangibles and licenses acquired through the Company’s acquisition of service and technology oriented companies in an effort to both support its clients and generate new future revenue streams. Other acquired intangible assets are amortized using the straight-line method over the estimated useful life of 10 to 15 years, with amortization included in other operating expenses. Each year the Company reviews other acquired intangibles to determine the recoverability of these balances. Other acquired intangibles totaled approximately $8 million and $11 million as of December 31, 2024 and 2023, respectively.
Other Assets	Property, Equipment, Leasehold Improvements and Computer Software Property, equipment and leasehold improvements, which are included in other assets, are stated at cost, less accumulated depreciation. Depreciation is determined using the straight-line method over the estimated useful lives of the assets, as appropriate. The estimated life is generally 40 years for company occupied real estate property, from one to seven years for leasehold improvements, and from three to seven years for all other property and equipment. The property, equipment and leasehold improvements totaled $325 million and $279 million as of December 31, 2024 and 2023, respectively.
Future Policy Benefits	FUTURE POLICY BENEFITS 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. It is the Company’s policy to complete its annual assumption review during the third quarter of each year. However, updates may occur in other quarters if information becomes available during the quarter that indicates an assumption update is necessary. Traditional Business Significant assumptions used to compute the liability for future policy benefits for the Traditional business include mortality, morbidity, lapse rates and discount rates (both accretion and current). During 2024 and 2023, the Company completed its annual assumption review resulting in a $39 million and $85 million increase in the Company’s liability for future policy benefits for its Traditional business during 2024 and 2023, respectively. The increase in the liability in 2024 and 2023 was primarily the result of updating the mortality and lapse assumptions used to measure the liability for future policy benefits. The Company also updated the underlying market data used to determine the current discount rate resulting in changes to the discount rate assumption used to measure the net liability for future policy benefits. 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 years ended December 31, 2024 and 2023 (dollars in millions): For the year ended December 31, 2024: 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 $ 76,943 $ 22,689 $ 15,328 $ 42,741 Effect of changes in cash flow assumptions 67 (592) 187 975 Effect of actual variances from expected experience (455) 333 593 368 Adjusted balance, beginning of year 76,555 22,430 16,108 44,084 Issuances (1) 5,844 549 1,144 3,965 Interest accrual (2) 3,494 741 532 1,140 Net premiums collected (3) (6,230) (994) (1,513) (2,258) Derecognition (4) (1,776) — — — Foreign currency translation (6) (1,798) (360) (2,130) Ending balance at original discount rate 77,881 20,928 15,911 44,801 Effect of changes in discount rate assumptions (8,683) (4,042) (2,767) (12,583) Balance, end of period $ 69,198 $ 16,886 $ 13,144 $ 32,218 Present Value of Expected Future Policy Benefits Beginning of year balance at original discount rate $ 89,036 $ 26,275 $ 16,756 $ 47,370 Effect of changes in cash flow assumptions 36 (620) 212 1,048 Effect of actual variances from expected experience (639) 331 601 289 Adjusted balance, beginning of year 88,433 25,986 17,569 48,707 Issuances (1) 5,844 549 1,135 3,989 Interest accrual (2) 4,078 955 574 1,305 Benefit payments (5) (5,853) (1,085) (1,501) (2,024) Derecognition (4) (1,783) — — — Foreign currency translation (8) (2,096) (412) (2,265) Ending balance at original discount rate 90,711 24,309 17,365 49,712 Effect of changes in discount rate assumptions (10,975) (3,323) (3,101) (14,891) Balance, end of period $ 79,736 $ 20,986 $ 14,264 $ 34,821 Liability for future policy benefits $ 10,538 $ 4,100 $ 1,120 $ 2,603 Less: reinsurance recoverable (810) (263) (22) (74) Net liability for future policy benefits $ 9,728 $ 3,837 $ 1,098 $ 2,529 Weighted-average duration of the liability (in years) 11 14 8 15 Weighted-average interest accretion rate 4.6 % 3.6 % 3.4 % 2.7 % Weighted-average current discount rate 5.7 % 4.8 % 5.6 % 4.7 % (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.

The Company’s Traditional business actual-to-expected variances, the effects of changes in cash flow assumptions and the effects of changes in discount rate assumption for the years ended December 31, 2024 and 2023 are summarized in the tables below: For the year ended December 31, 2024: Segment Liability for future policy benefits at original discount rate Changes in cash flow assumptions Actual-to-expected variance Impact of updating discount rate recognized in OCI U.S. and Latin America – Traditional $12.8 billion $(31) million $(184) million $(1.2) billion Canada – Traditional $3.4 billion $(28) million $(2) million $(152) million Europe, Middle East and Africa – Traditional $1.5 billion $25 million $8 million $(115) million Asia Pacific – Traditional $4.9 billion $73 million $(79) million $(343) million For the year ended December 31, 2023: Segment Liability for future policy benefits at original discount rate Changes in cash flow assumptions Actual-to-expected variance Impact of updating discount rate recognized in OCI U.S. and Latin America – Traditional $12.1 billion $17 million $82 million $458 million Canada – Traditional $3.6 billion $12 million $9 million $245 million Europe, Middle East and Africa – Traditional $1.4 billion $47 million $13 million $(50) million Asia Pacific – Traditional $4.6 billion $9 million $(45) million $(34) million Financial Solutions Business Significant assumptions used to compute the liability for future policy benefits for the Financial Solutions business include mortality, morbidity, lapse rates and discount rates (both accretion and current). During 2024 and 2023, the Company completed its annual assumption review resulting in a $20 million increase and $78 million decrease in the Company’s liability for future policy benefits for its Financial Solutions business during 2024 and 2023, respectively. The increase and decrease in the liability in 2024 and 2023 were primarily the result of updating the lapse and mortality assumptions used to measure the liability for future policy benefits. The Company also updated the underlying market data used to determine the current discount rate resulting in changes to the discount rate assumption used to measure the net liability for future policy benefits. The following tables provide the balances of and changes in the Company’s liability for future policy benefits, including the deferred profit liability related to the longevity business, for its Financial Solutions business, which primarily consists of longevity reinsurance, asset-intensive products, primarily annuities and financial reinsurance for the years ended December 31, 2024 and 2023 (dollars in millions): For the year ended December 31, 2024: U.S. and Latin America – Financial Solutions Canada – Financial Solutions Europe, Middle East and Africa – Financial Solutions Asia Pacific – Financial Solutions Present Value of Expected Net Premiums Beginning of year balance at original discount rate $ 1,455 $ 3,184 $ 54,832 $ 2,057 Effect of changes in cash flow assumptions 12 — (93) 1 Effect of actual variances from expected experience 73 (7) 1,081 (2) Adjusted balance, beginning of year 1,540 3,177 55,820 2,056 Issuances (1) 2,807 5,346 21,381 7,995 Interest accrual (2) 45 131 1,947 29 Net premiums collected (3) (3,046) (4,752) (5,846) (7,100) Derecognition (4) — — — — Foreign currency translation — (288) (1,942) (222) Ending balance at original discount rate 1,346 3,614 71,360 2,758 Effect of changes in discount rate assumptions (254) (187) (8,636) (294) Balance, end of period $ 1,092 $ 3,427 $ 62,724 $ 2,464 Present Value of Expected Future Policy Benefits Beginning of year balance at original discount rate $ 6,843 $ 3,210 $ 60,938 $ 8,019 Effect of changes in cash flow assumptions 20 — (90) 10 Effect of actual variances from expected experience 67 (7) 1,081 (9) Adjusted balance, beginning of year 6,930 3,203 61,929 8,020 Issuances (1) 2,934 5,372 21,381 7,995 Interest accrual (2) 382 276 2,169 191 Benefit payments (5) (757) (423) (5,114) (460) Derecognition (4) — — — — Foreign currency translation — (494) (2,075) (1,120) Ending balance at original discount rate 9,489 7,934 78,290 14,626 Effect of changes in discount rate assumptions (651) 5 (9,531) (1,880) Balance, end of period $ 8,838 $ 7,939 $ 68,759 $ 12,746 Cumulative amount of fair value hedging adjustments (7) — — — Liability for future policy benefits $ 7,739 $ 4,512 $ 6,035 $ 10,282 Less: reinsurance recoverable (1,373) — — — Net liability for future policy benefits $ 6,366 $ 4,512 $ 6,035 $ 10,282 Weighted-average duration of the liability (in years) 8 13 10 14 Weighted-average interest accretion rate 4.0 % 4.5 % 3.1 % 1.5 % Weighted-average current discount rate 5.6 % 4.7 % 5.2 % 3.1 % (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.

Other Liabilities	Other Liabilities Other liabilities primarily include investments in transit, separate accounts, employee benefits, cash collateral received on derivative positions, and derivatives in a liability position.
Income Taxes	Income Taxes The U.S. consolidated tax return includes the operations of RGA and all eligible subsidiaries. The Company’s foreign subsidiaries are taxed under applicable local statutes. The Company provides for federal, state and foreign income taxes currently payable, as well as those deferred due to temporary differences between the tax basis of assets and liabilities and the reported amounts and are recognized in net income or in certain cases in other comprehensive income (loss). The Company’s accounting for income taxes represents management’s best estimate of various events and transactions considering the laws enacted as of the reporting date. Deferred tax assets and liabilities are measured by applying the relevant jurisdictions’ enacted tax rate for the period in which the temporary differences are expected to reverse to the temporary difference change for that period. The Company will establish a valuation allowance if management determines, based on available information, that it is more likely than not that deferred income tax assets will not be realized. The Company has deferred tax assets including those related to foreign tax credits, net operating, and capital losses. The Company has projected its ability to utilize its deferred tax assets and established a valuation allowance on the portion of the deferred tax assets the Company believes more likely than not will not be realized. Significant judgment is required in determining whether valuation allowances should be established as well as the amount of such allowances. When making such a determination, consideration is given to, among other things, the following: (i) taxable income in prior carryback years; (ii) future reversals of existing taxable temporary differences; (iii) future taxable income exclusive of reversing temporary differences and carryforwards; and (iv) tax planning strategies. Any such changes could significantly affect the amounts reported in the consolidated financial statements in the year these changes occur. It is the Company’s policy to account for global intangible low-taxed income (“GILTI”) as a period cost. The Company reports uncertain tax positions in accordance with generally accepted accounting principles. In order to recognize the benefit of an uncertain tax position, the position must meet the more likely than not criteria of being sustained. Unrecognized tax benefits due to tax uncertainties that do not meet the more likely than not criteria are included within income tax liabilities and are expensed in the period that such determination is made. The Company classifies interest related to tax uncertainties as interest expense whereas penalties related to tax uncertainties are classified as a component of income tax. See Note 14 – “Income Tax” for further discussion.

Share-based Payment Arrangement [Policy Text Block]	Equity Based Compensation The Company expenses the fair value of stock awards included in its incentive compensation plans. The fair value of the award is expensed over the performance or service period, which generally corresponds to the vesting period, and is recognized as an increase to additional paid-in-capital in stockholders’ equity, and stock based compensation expense is reflected in other operating expenses.
Earnings Per Share	Earnings Per Share Basic earnings per share is calculated based on the weighted average number of common shares outstanding during the period. Diluted earnings per share include the dilutive effects assuming the exercise or issuance of stock awards.
Revenue	Premium and Fee Revenue and Receivable Recognition Premium and Fee Revenue Life and health premiums are recognized as revenue when due from the insured and are reported net of amounts retroceded. Benefits and expenses are reported net of amounts retroceded and are associated with earned premiums so that profits are recognized over the life of the related contract. This association is accomplished through the provision for future policy benefits and the amortization of deferred policy acquisition costs. Other revenue includes items such as certain treaty recapture fees related to short duration products, fees associated with financial reinsurance and policy changes on interest-sensitive and investment-type products that the Company reinsures. Any fees that are collected in advance of the period benefited are deferred and recognized over the period benefited. The Company reinsures medical, disability, life and other products for fixed period of short-duration, typically one to three years. Premiums for short-duration products are recognized over the coverage period in proportion to the amount of insurance protection provided. For certain reinsurance transactions involving the reinsurance of in force blocks of business, the ceding company pays a premium equal to the initial required reserve (future policy benefit). In such transactions, for income statement presentation, the Company nets the expense associated with the establishment of the reserve against the premiums from the transaction. Premiums related to pension risk transfer transactions are recognized when due, and partially offset by an increase in the liability for future policy benefits. Revenues for interest-sensitive and investment-type products consist of investment income, policy charges for the cost of insurance, policy administration, and surrender charges that have been assessed against policy account balances during the period. Interest-sensitive contract liabilities for these products represent policy account balances before applicable surrender charges. Policy benefits and claims that are charged to expenses include claims incurred in the period in excess of related policy account balances and interest credited to policy account balances. Interest is credited to policyholder account balances according to terms of the policies or contracts. For each of its reinsurance contracts, the Company must determine if the contract provides indemnification against loss or liability relating to insurance risk, in accordance with GAAP. The Company must review all contractual features, particularly those that may limit the amount of insurance risk to which the Company is subject or features that delay the timely reimbursement of claims. If the Company determines that a contract does not expose it to a reasonable possibility of a significant loss from insurance risk, the Company records the contract on a deposit method of accounting with any net amount receivable reflected as an asset within premiums receivable and other reinsurance balances, and any net amount payable reflected as a liability within other reinsurance balances. Fees earned on the contracts are reflected as other revenues, rather than premiums. Premium Receivable Premiums are accrued when due and in accordance with information received from the ceding company. When the Company enters into a new reinsurance agreement, it accrues premium based on the terms of the reinsurance treaty. Similarly, when a ceding company fails to report information on a timely basis, the Company records accruals based on the terms of the reinsurance treaty as well as historical experience. Other management estimates include adjustments for increased in force on existing treaties, lapsed premiums given historical experience, the financial health of specific ceding companies, collateral value and the legal right of offset on related amounts (i.e., allowances and claims) owed to the ceding company. Under the legal right of offset provisions in its reinsurance treaties, the Company can withhold payments for allowances and claims from unpaid premiums. Based on its review of these factors and historical experience, the Company did not believe a provision for doubtful accounts was necessary as of December 31, 2024 or 2023.
Insurance Contract, Acquisition Cost	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 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 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 consolidated statements of income (loss).
Short-Duration Contracts, Policy	Unpaid Claims and Claim Expense – Short-Duration Contracts The Company provides reinsurance of medical, disability, life and other products for a fixed period of short-duration, typically one to three years. Under the short-duration insurance accounting model, claims or benefits are recognized when insured events occur, based on the ultimate cost to settle the claim, and are adjusted to reflect changes in estimates during the life of the contract. The estimated cost to settle the claim is based on actuarial assumptions for similar claims. The Company also establishes an incurred but not reported (“IBNR”) liability based on historical reporting patterns.
Market Risk Benefit	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 (loss). 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.
Reinsurance Accounting Policy	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
Funds Withheld Payable Policy Text Block	Funds Withheld Payable The Company has entered into reinsurance agreements under which it records a funds withheld payable that contains an embedded derivative. The fair value of the embedded derivative is estimated based on the fair value of the assets withheld that support the funds withheld payable. The change in the fair value of the embedded derivative is included in investment related gains (losses), net and investment income earned on the withheld assets is included in other insurance expenses.
Operating Joint Ventures	Operating Joint Ventures The Company has made investments in certain joint ventures that are strategic in nature and made other than for the sole purpose of generating investment income. These investments are reported under the equity method of accounting and are included in other assets. The Company’s share of earnings from these joint ventures is reported in other revenues on the consolidated statements of income. The Company’s investments in operating joint ventures do not have a material effect on the Company’s results of operations and financial condition, and as a result no additional disclosures have been presented.
Liability for Future Policy Benefit	Future Policy Benefits Utilizing the net premium model, a liability for future policy benefits for life, pension risk transfer transactions, 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 completed 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 2024 and 2023. 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 and pension risk transfer transactions 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 consolidated statements of income. The locked-in discount curve at contract inception for contracts entered into after January 1, 2021, 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 January 1, 2021, are 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. 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 consolidated balance sheets.

Liability for Future Policy Benefit, Activity	Traditional Business Significant assumptions used to compute the liability for future policy benefits for the Traditional business include mortality, morbidity, lapse rates and discount rates (both accretion and current). During 2024 and 2023, the Company completed its annual assumption review resulting in a $39 million and $85 million increase in the Company’s liability for future policy benefits for its Traditional business during 2024 and 2023, respectively. The increase in the liability in 2024 and 2023 was primarily the result of updating the mortality and lapse assumptions used to measure the liability for future policy benefits. The Company also updated the underlying market data used to determine the current discount rate resulting in changes to the discount rate assumption used to measure the net liability for future policy benefits. 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 years ended December 31, 2024 and 2023 (dollars in millions): For the year ended December 31, 2024: 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 $ 76,943 $ 22,689 $ 15,328 $ 42,741 Effect of changes in cash flow assumptions 67 (592) 187 975 Effect of actual variances from expected experience (455) 333 593 368 Adjusted balance, beginning of year 76,555 22,430 16,108 44,084 Issuances (1) 5,844 549 1,144 3,965 Interest accrual (2) 3,494 741 532 1,140 Net premiums collected (3) (6,230) (994) (1,513) (2,258) Derecognition (4) (1,776) — — — Foreign currency translation (6) (1,798) (360) (2,130) Ending balance at original discount rate 77,881 20,928 15,911 44,801 Effect of changes in discount rate assumptions (8,683) (4,042) (2,767) (12,583) Balance, end of period $ 69,198 $ 16,886 $ 13,144 $ 32,218 Present Value of Expected Future Policy Benefits Beginning of year balance at original discount rate $ 89,036 $ 26,275 $ 16,756 $ 47,370 Effect of changes in cash flow assumptions 36 (620) 212 1,048 Effect of actual variances from expected experience (639) 331 601 289 Adjusted balance, beginning of year 88,433 25,986 17,569 48,707 Issuances (1) 5,844 549 1,135 3,989 Interest accrual (2) 4,078 955 574 1,305 Benefit payments (5) (5,853) (1,085) (1,501) (2,024) Derecognition (4) (1,783) — — — Foreign currency translation (8) (2,096) (412) (2,265) Ending balance at original discount rate 90,711 24,309 17,365 49,712 Effect of changes in discount rate assumptions (10,975) (3,323) (3,101) (14,891) Balance, end of period $ 79,736 $ 20,986 $ 14,264 $ 34,821 Liability for future policy benefits $ 10,538 $ 4,100 $ 1,120 $ 2,603 Less: reinsurance recoverable (810) (263) (22) (74) Net liability for future policy benefits $ 9,728 $ 3,837 $ 1,098 $ 2,529 Weighted-average duration of the liability (in years) 11 14 8 15 Weighted-average interest accretion rate 4.6 % 3.6 % 3.4 % 2.7 % Weighted-average current discount rate 5.7 % 4.8 % 5.6 % 4.7 % (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.
