Fair Value Disclosures [Abstract]

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, 2023 and 2022 are summarized below (dollars in millions):

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 the underlying products in reinsurance treaties, primarily equity-indexed and variable annuity treaties, the Company utilizes a discounted cash flow model, which includes an estimate of future equity option purchases and an adjustment for a CVA. The variable annuity embedded derivative calculations are performed by third parties based on methodology and input assumptions provided by the Company. To validate the reasonableness of the resulting fair value, the Company’s internal actuaries perform reviews and analytical procedures on the results. The capital market inputs to the model, such as equity indexes, short-term equity volatility and interest rates, 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 – All of the derivative instruments utilized by the Company are 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.

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 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):

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, 2023 and 2022, the Company did not have any material assets that were measured at fair value due to impairment.

Fair Value of Financial Instruments Carried at Other Than Fair Value

The following table presents the carrying values and estimated fair values of the Company’s financial instruments, which were not measured at fair value on a recurring basis, as of December 31, 2023 and 2022 (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.

(1)Carrying values presented herein may differ from those in the Company’s consolidated balance sheets because certain items within the respective financial statement captions may be measured at fair value on a recurring basis.

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 significant management judgment. The valuation of interest-sensitive contract liabilities is considered Level 3 in the fair value hierarchy.

Long-term Debt – The fair value of the Company’s long-term debt, and collateral finance and securitization notes is generally estimated by discounting future cash flows using market rates currently available for debt with similar remaining maturities and reflecting the credit risk of the Company, including inputs when available, from actively traded debt of the Company or other companies with similar credit quality. The valuation of long-term debt, and collateral finance and securitization notes is generally obtained from brokers and is considered Level 3 in the fair value hierarchy.

RGA has entered into an interest rate swap on its Variable Rate Junior Subordinated Debentures that effectively fixes the interest rate on these securities at 4.82% until December 2037.

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, 2023, the amount outstanding is $475 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.

On September 15, 2022, RGA announced a cash tender offer for any and all of its outstanding 6.20% Fixed-to-Floating Rate Subordinated Debentures due 2042 (the “2042 Debentures”) at a price of $25.20 for each $25 principal amount. The tender offer expired on September 22, 2022, and a total of $151 million or approximately 38%, of the aggregate principal amount of the 2042 Debentures were tendered. The Company redeemed the remaining debentures in accordance with the indenture governing the 2042 Debentures on December 15, 2022.

On September 23, 2022, RGA issued 7.125% fixed-rate reset subordinated debentures due October 15, 2052, with a face amount of $700 million. This security has been registered with the Securities and Exchange Commission. The net proceeds were approximately $690 million and a portion was used to pay for the tender offer and redemption of the 2042 Debentures. The remaining proceeds will be used for general corporate purposes. Capitalized issue costs were approximately $9 million.

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, 2023 and 2022, the Company had $4,464 million and $3,993 million, respectively, in outstanding borrowings under its debt agreements and was in compliance with all covenants under those agreements. As of December 31, 2023 and 2022, the average interest rate on long-term debt outstanding was 5.09% and 4.71%, 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, 2023, were as follows (dollars in millions):

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, 2023 and 2022, there were approximately $54 million and $128 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, 2023 and 2022, $728 million and $1.5 billion, 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 Company maintains seven committed credit facilities, a syndicated revolving credit facility and six letter of credit facilities. The committed credit facilities have a combined capacity of $928 million while the syndicated revolving credit facility is for $850 million and the remaining letter of credit facilities have a capacity of $1.3 billion. The Company may borrow cash and obtain letters of credit in multiple currencies under its syndicated revolving credit facility. The following table provides additional information on the Company’s existing committed credit facilities as of December 31, 2023 and 2022 (dollars in millions):

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. Overfunded 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 status of these plans as of December 31, 2023 and 2022 is summarized below (dollars in millions):

The Company has met the minimum funding requirements for its qualified pension plans and is not required to contribute to the qualified pension plans during 2024. The Company has not determined whether, and to what extent, contributions may be made to the qualified pension plans in 2024. During 2024, the Company expects to contribute $7 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):

Assumptions

The weighted average assumptions used to determine the benefit obligation and net periodic benefit cost were as follows:


	Pension Benefits						Other Benefits
	2023		2022		2021		2023		2022		2021
Benefit obligation
Discount rate	4.78	%	5.00	%	2.64	%	4.79	%	4.99	%	2.76	%
Rate of compensation increase	4.71	%	4.96	%	4.74	%	n/a		n/a		n/a
Net periodic benefit cost
Discount rate	5.01	%	2.65	%	2.21	%	4.99	%	2.76	%	2.41	%
Expected long-term rate of return on plan assets	7.00	%	6.50	%	6.50	%	n/a		n/a		n/a
Rate of compensation increase	4.97	%	4.75	%	4.71	%	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,
	2023		2022
Health care cost trend rates assumed for next year	6.50	%	7.00	%
Ultimate cost trend rate	4.50	%	4.50	%
Year ultimate trend is reached	2028		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 2023, and 60% equity securities and 40% debt securities for 2022. 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, 2023 and 2022 are summarized below (dollars in millions):


	December 31, 2023
			Fair Value Measurement Using:
	Total		Level 1		Level 2		Level 3

Total	$	180	$	180	$	—	$	—

(1)Mutual funds were invested 23% in U.S. equity funds, 36% in U.S. fixed income funds, 25% in non-U.S. equity funds and 16% in other.

(2)Exchange traded funds were invested 100% in U.S. equity funds.


	December 31, 2022

(3)Mutual funds were invested 25% in U.S. equity funds, 40% in U.S. fixed income funds, 16% in non-U.S. equity funds and 19% in other.

As of December 31, 2023 and 2022, the Company classified all of its qualified pension plan assets in the Level 1 category as quoted prices in active markets are available for these assets. 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 $27 million, $23 million and $21 million in 2023, 2022 and 2021, respectively.

COMMITMENTS, CONTINGENCIES AND GUARANTEES

Commitments

Funding of Investments

The Company’s commitments to fund investments as of December 31, 2023 and 2022, are presented in the following table (dollars in millions):


	2023		2022
Limited partnerships and real estate joint ventures	$	1,058	$	937
Mortgage loans	137		137

Bank loans and private placements	810		682
Lifetime mortgages	53		59

The Company anticipates that the majority of its current commitments will be invested over the next five years; however, these commitments could become due any time at the request of the counterparties. Bank loans and private placements are included in fixed maturity securities available-for-sale.

The Company has an immaterial liability, included in other liabilities, for current expected credit losses associated with unfunded commitments as of December 31, 2023 and 2022.

Off-Balance Sheet Arrangements

In 2013, the Company executed a series of incentive agreements with the County of St. Louis, Missouri (the “County”). Under these agreements, the Company transferred ownership in its newly constructed world headquarters to the County in exchange

for taxable industrial revenue bonds (the “bonds”), in a series of bond issuances during 2013 and 2014, with a maximum amount of $150 million. As a result, the Company was able to reduce the cost of constructing and operating its world headquarters by reducing certain state and local tax expenditures. The Company simultaneously leased the world headquarters from the County and has an option to purchase the world headquarters for a nominal fee upon tendering the bonds back to the County. The payments due to the Company under the terms of the bonds and the amounts owed by the Company under the terms of the lease agreement qualify for the right of offset under GAAP. As such, neither the bonds nor the lease obligation is recorded on the consolidated balance sheets as an asset or liability, respectively. The world headquarters is recorded as an asset of the Company in “Other assets” on the consolidated balance sheets.

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, 2023 and 2022, the Company had $1.1 billion and $1.3 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, 2023 and 2022, the Company had $1.3 billion and $900 million of FABN agreements outstanding, which are included within interest-sensitive contract liabilities. In January 2024, the Company issued additional FABN agreements totaling $700 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, 2023, the Company does not believe that it will be required to provide any funding under these commitments as the occurrence of the defined events is considered remote. The following table presents the maximum potential obligation for these commitments as of December 31, 2023 (dollars in millions):


Commitment Period	Maximum Potential Obligation

The calculation of common equivalent shares does not include the impact of stock awards with a conversion price that exceeds the average stock price for the earnings period as the result would be antidilutive. The calculation of common equivalent shares also excludes the impact of outstanding performance contingent awards as the conditions necessary for their issuance have not been satisfied as of the end of the reporting period.

Unpaid Claims and Claim Expense Short Duration Contracts

12 Months Ended

Dec. 31, 2023

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 2023.

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 2014.

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. Therefore, it is impractical to provide meaningful claim count detail by accident year in the tables shown below.

Net balance, end of period	2,650		2,423
Plus: reinsurance recoverable	80		57
Balance, end of period	$	2,730	$	2,480

Incurred claims associated with prior periods are primarily due to the development of claims for prior years being different than were anticipated when the liabilities for unpaid claims were originally estimated. These trends have been considered in establishing the current year liability for unpaid claims.

Financial Condition and Net Income on a Statutory Basis - Significant Subsidiaries

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.

*Prior period amounts have been updated to reflect the entity’s adoption of LDTI or International Financial Reporting Standards No. 17

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,
	2023		2022
Prescribed practice – surplus	$	340	$	527
Prescribed practice – letters of credit	(426)		(301)
Surplus (deficit) – NAIC SAP	$	(86)	$	226

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 $532 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.

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.

Equity Derivatives

Equity index options are used by the Company primarily to hedge minimum guarantees embedded in certain variable annuity products. To hedge against adverse changes in equity indices, the Company buys put 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

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 equity-indexed annuity contracts with benefits that are considered embedded derivatives. The changes in fair values of embedded derivatives on equity-indexed annuities described below relate to changes in the fair value associated with capital market and other related assumptions.

Summary of Derivative Positions

Derivatives, except for embedded derivatives, are included in other invested assets or other liabilities, at fair value. Embedded derivative assets and liabilities on modco or funds withheld arrangements are included on the consolidated balance sheets with the host contract in funds withheld at interest or funds withheld payable, at fair value. Embedded derivative liabilities on indexed annuity products are included on the consolidated balance sheets with the host contract in interest-sensitive contract liabilities, at fair value. The following table presents the notional amounts and gross fair value of derivative instruments prior to taking into account the netting effects of master netting agreements as of December 31, 2023 and 2022 (dollars in millions):

Fair Value Hedges

The Company designates and reports the following as fair value hedges when they meet the requirements of the general accounting principles for Derivatives and Hedging: (i) certain foreign currency swaps to hedge the foreign currency fair value exposure of foreign currency denominated assets; and (ii) interest rate swaps to convert fixed rate liabilities to floating rate liabilities. 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, 2023, 2022 and 2021 were as follows (dollars in millions):

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.

As of December 31, 2023, approximately $13 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 $9 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.

For the years ended December 31, 2023, 2022 and 2021, there were no material amounts reclassified into earnings relating to instances in which the Company discontinued cash flow hedge accounting because the forecasted transaction did not occur by the anticipated date or within the additional time period permitted by the authoritative guidance for the accounting for derivatives and hedging.

Hedges of Net Investments in Foreign Operations

The Company uses foreign currency swaps and foreign currency forwards to hedge a portion of its net investment in certain foreign operations against adverse movements in exchange rates. The following table illustrates the Company’s net investments in foreign operations (“NIFO”) hedges and the gains (losses) deferred in OCI for the years ended December 31, 2023, 2022 and 2021 (dollars in millions):


	Derivative Gains (Losses) Deferred in OCI
	For the years ended December 31,
Derivative Type	2023		2022		2021
Foreign currency swaps	$	—	$	—	$	(2)
Foreign currency forwards	(18)		73		—
Total	$	(18)	$	73	$	(2)

The cumulative foreign currency translation gain recorded in AOCI related to these hedges was $192 million and $210 million as of December 31, 2023 and 2022, 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.

Netting Arrangements and Credit Risk

Certain of the Company’s derivatives are subject to enforceable master netting arrangements and reported as a net asset or liability in the consolidated balance sheets. The Company nets all derivatives that are subject to such arrangements.

The Company has elected to include all derivatives, except embedded derivatives, in the table below, irrespective of whether they are subject to an enforceable master netting arrangement or a similar agreement. See Note 11 – “Investments” for information regarding the Company’s securities borrowing, lending, and repurchase/reverse repurchase agreements. 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, 2023 and December 31, 2022 (dollars in millions):


	Gross Amounts Recognized		Gross Amounts Offset in the Balance Sheet		Net Amounts Presented in the Balance Sheet		Financial Instruments/Collateral (1)		Net Amount
December 31, 2023:
Derivative assets	$	154	$	(57)	$	97	$	(97)	$	—
Derivative liabilities	254		(57)		197		(197)		—
December 31, 2022:
Derivative assets	$	223	$	(53)	$	170	$	(170)	$	—
Derivative liabilities	236		(53)		183		(183)		—

(1)Includes initial margin posted to a central clearing partner for financial instruments and excludes the excess of collateral received/pledged from/to the counterparty.

The Company may be exposed to credit-related losses in the event of non-performance by counterparties to derivative financial instruments. Generally, the credit exposure of the Company’s derivative contracts is limited to the fair value and accrued interest of non-collateralized derivative contracts in an asset position at the reporting date. As of December 31, 2023, 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. 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.

Future Policy Benefits

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.

During 2023, the Company completed its annual assumption review resulting in a decrease in its total liability for future policy benefits. The decrease was primarily the result of updated mortality assumptions, which had a favorable impact on the liability for future policy benefits for the Company’s Financial Solutions business and an unfavorable impact on the Company’s Traditional business.

During 2022, the Company’s assumption review resulted in an increase in its total liability for future policy benefits. The increase was primarily the result of updated mortality assumptions, which had an unfavorable impact on the liability for future policy benefits for the Company’s Traditional business. There were no significant changes in the assumptions used to measure the liability for future policy benefits for the Company’s Financial Solutions business.

Traditional Business

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, 2023 and 2022 (dollars in millions):

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 2023 and 2022, the Company updated its assumptions which resulted in a $85 million and $222 million increase, excluding the effects of reinsurance, in the Company’s liability for future policy benefits for its Traditional business. Including the effects of reinsurance, a future policy benefits remeasurement loss of $75 million and $259 million was recognized for the years ending December 31, 2023 and 2022, respectively, as a result of changes in cash flow assumptions. The increase in the liability in 2023 and 2022 was primarily the result of updating the 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 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, 2023 and 2022 are summarized in the tables below:

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 2023 and 2022, the Company updated its assumptions which resulted in a $78 million and $17 million decrease, excluding the effects of reinsurance, in the Company’s liability for future policy benefits for its Financial Solutions business during 2023 and 2022, respectively. Including the effects of reinsurance, a future policy benefits remeasurement gain of $78 million and $17 million was recognized during the years ending December 31, 2023 and 2022, respectively, as a result of changes in cash flow assumptions. The decrease in the liability in 2023 and 2022 was primarily the result of updating the 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 Company’s Financial Solutions business actual-to-expected variances (including the effects of model updates), the effects of changes in cash flow assumptions and the effects of changes in discount rate assumptions for the years ended December 31, 2023 and 2022 are summarized in the tables below:

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 treaty recapture fees, 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 reinsurers 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 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 surrenders 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 records accruals 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, 2023 or 2022.

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 2023 and 2022. 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 the adoption of ASU 2018-12 (i.e., January 1, 2021, and after) is based on the average upper-medium grade fixed-income instrument yields during the first calendar year of the reinsurance contract. The locked-in discount rates at contract inception for contracts that were effective prior to the adoption of ASU 2018-12 (i.e., prior to January 1, 2021) are the discount rate assumptions used prior to the adoption of ASU 2018-12, which were based on estimates of expected investment yields.

Included in the liability for future policy benefits are unpaid claims related to long-duration contracts and an accrual for incurred but not reported losses (“IBNR”). The Company’s IBNR accrual related to long-duration contracts is determined using case-basis estimates and lag studies of past experience. The time lag from the date of the claim or death to when the ceding company reports the claim to the Company can vary significantly by ceding company, business segment and product type. 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. Prior to the adoption of ASU 2018-12, unpaid claims and IBNR related to long-duration contracts were included in other policy claims and benefits. Upon adoption of ASU 2018-12, the Company revised prior period amounts to conform to the current period’s presentation. See Note 2 – “Impact of New Accounting Standard” for additional information.

Interest-Sensitive Contract Liabilities and Policyholder Account Balances

Liabilities for future benefits on interest-sensitive life and investment-type contract liabilities are carried at the accumulated contract holder values without reduction for potential surrender or withdrawal charges. The Company reinsures asset-intensive products, including annuities and corporate-owned life insurance. The investment portfolios for these products are segregated for management purposes within the general account of the respective legal entity. The liabilities under asset-intensive insurance contracts or reinsurance contracts reinsured on a coinsurance basis are included in interest-sensitive contract liabilities on the 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 as well as related adjustments to deferred acquisition costs, if applicable, 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. 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 105% 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 accumulated other comprehensive income (loss) (“AOCI”).

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 charged off 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.

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 annuity products that contain terms that are deemed to be embedded derivatives, primarily equity-indexed annuities. 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 or 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 funds withheld at interest and funds withheld payable on the consolidated balance sheet, 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

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 net asset value (“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.

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 charged to earnings 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 including the impact of the December 27, 2023, enactment of the Bermuda corporate income tax regime and enactment of numerous Organization for Economic Cooperation Pillar II regimes.

Other Accounting Policies

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.

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.

Acquired Intangibles

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 $6 million and $12 million as of December 31, 2023 and 2022, 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 $11 million and $14 million as of December 31, 2023 and 2022, respectively.

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 $279 million and $270 million as of December 31, 2023 and 2022, respectively.

Computer software, which is included in other assets, is stated at cost, less accumulated amortization. Purchased software costs, as well as certain internal and external costs incurred to develop internal-use computer software during the application development stage, are capitalized. Amortization of software costs is recorded on a straight-line basis over periods ranging from three to ten years. Carrying values are reviewed at least annually for indicators of impairment in value. Unamortized computer software costs were $137 million and $138 million at December 31, 2023 and 2022, respectively.

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.

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.

Other Liabilities

Other liabilities primarily include investments in transit, separate accounts, employee benefits, and cash collateral received on derivative positions.

Foreign Currency Translation

Assets, liabilities and results of foreign operations are recorded based on the functional currency of each foreign operation. The determination of the functional currency is based on economic facts and circumstances pertaining to each foreign operation. The Company’s material functional currencies are the U.S. dollar, Canadian dollar, British pound, Australian dollar, Japanese yen, Korean won, Euro and South African rand. The translation of the functional currency into U.S. dollars is performed for balance sheet accounts using current exchange rates in effect at the balance sheet date and for revenue and expense accounts using weighted-average exchange rates during each year. Gains or losses, net of applicable deferred income taxes, resulting from such translation are included in accumulated currency translation adjustments, in AOCI until the underlying functional currency operation is sold or substantially liquidated.

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

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.

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. In the individual life markets, the Company retains a maximum of $8 million of coverage per individual life. 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 $8 million 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 $8 million 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, 2023 and 2022, 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, 2023, all rated retrocession pool participants followed by the A.M. Best Company were rated “A- (excellent)” or better. The Company verifies retrocession pool participants’ ratings on a quarterly basis. For a majority of the retrocessionaires 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.

During the fourth quarter of 2023, 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. The Company completed a coinsurance funds withheld transaction under which it retroceded $2.5 billion of existing liabilities associated with asset-intensive business to Ruby Re.

Excluding amounts retroceded to Ruby Re, two major reinsurance companies account for approximately 74% of reinsurance ceded receivables and other as of December 31, 2023.

As of December 31, 2023 and 2022, $10 million and $16 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 $3.1 billion and $1.5 billion as of December 31, 2023 and 2022, respectively.

The effect of reinsurance on net premiums is as follows (dollars in millions):

December 31, 2021	1,117		3,467,054		166,842		3,301,329		105.0

Fund Withheld

Certain of the Company’s retrocession agreements, including those with Ruby Re, are on a 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 are reported in other reinsurance expense and net realized gains (losses) related to the assets is 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 sheet as of December 31, 2023 and 2022 (dollars in millions):


	For the years ended December 31,
	2023		2022
Fixed maturity securities available-for-sale	$	2,442	$	203
Equity securities	2		1
Mortgage loans	451		18

Short-term investments and cash and cash equivalents	30		1
Accrued investment income	28		3
Net other assets	1		—
Net assets	$	4,534	$	1,822

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 $4,483 million and $1,486 million funds withheld payable, net of an embedded derivative asset of $206 million and $361 million as of December 31, 2023 and 2022, respectively.

Assumed Reinsurance

At December 31, 2023 and 2022, respectively, the Company provided approximately $28.3 billion and $28.7 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, 2023, 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 $3.5 billion and $3.7 billion were held in trust for the benefit of the Company’s subsidiaries to satisfy collateral requirements for reinsurance business at December 31, 2023 and 2022, respectively. Additionally, securities with an amortized cost of $32.8 billion and $31.5 billion as of December 31, 2023 and 2022, 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.

Segment Reporting [Abstract]

Segment Information

SEGMENT INFORMATION

The Company has geographic-based and business-based operational segments. Geographic-based operations are further segmented into traditional and financial solutions businesses.

The U.S. and Latin America Traditional segment provides individual and group life and health reinsurance to domestic clients for a variety of products through yearly renewable term agreements, coinsurance, and modified coinsurance. The U.S. and Latin America Financial Solutions segment includes asset-intensive products that concentrate on the investment risk within underlying annuities and corporate-owned life insurance policies, financial reinsurance, and capital solutions that assists ceding

companies in meeting applicable regulatory requirements while enhancing their financial strength and regulatory surplus position.

The Canada Traditional segment is primarily engaged in individual life reinsurance, and to a lesser extent creditor, group life and health, critical illness and disability reinsurance, through yearly renewable term and coinsurance agreements. The Canada Financial Solutions segment concentrates on assisting clients with longevity risk transfer structures within underlying annuities and pension benefit obligations and provides capital solutions to assist clients in meeting applicable regulatory requirements while enhancing their financial strength and regulatory surplus position through financial reinsurance and other capital solutions structures.

The Europe, Middle East and Africa Traditional segment provides individual and group life and health products through yearly renewable term and coinsurance agreements, reinsurance of critical illness coverage that provides a benefit in the event of the diagnosis of a pre-defined critical illness and underwritten annuities. The Europe, Middle East and Africa Financial Solutions segment provides longevity, asset-intensive and financial reinsurance. Longevity reinsurance takes the form of closed block annuity reinsurance and longevity swap structures.

The Asia Pacific Traditional segment provides individual and group life and health reinsurance, critical illness coverage, disability and superannuation through yearly renewable term and coinsurance agreements. The Asia Pacific Financial Solutions segment provides financial reinsurance, asset-intensive and certain disability and life blocks.

Corporate and Other revenues primarily include investment income from unallocated invested assets, investment related gains and losses 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 overhead and executive costs, interest expense related to debt, and the investment income and expense associated with the Company’s collateral finance and securitization transactions and service business expenses. Additionally, Corporate and Other includes results that, among other activities, develop and market technology, and provide consulting and outsourcing solutions for the insurance and reinsurance industries. The Company invests in this area in an effort to both support its clients and accelerate the development of new solutions and services to increase consumer engagement within the life industry.

The accounting policies of the segments are the same as those described in Note 2 – “Significant Accounting Policies and Pronouncements.” The Company measures segment performance primarily based on profit or loss from operations before income taxes. There are no intersegment reinsurance transactions and the Company does not have any material long-lived assets.

The Company allocates capital to its segments based on an internally developed economic capital model, the purpose of which is to measure the risk in the business and to provide a basis upon which capital is deployed. The economic capital model considers the unique and specific nature of the risks inherent in the Company’s businesses. As a result of the economic capital allocation process, a portion of investment income is attributed to the segments based on the level of allocated capital. 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.

Information related to revenues, income (loss) before income taxes, interest expense, depreciation and amortization, and assets of the Company’s operations are summarized below (dollars in millions):

Accounting Changes and Error Corrections [Abstract]

Accounting Standards Update and Change in Accounting Principle

IMPACT OF NEW ACCOUNTING STANDARD

As discussed in Note 1, the Company adopted ASU 2018-12 during the first quarter of 2023. The updated guidance materially changed how the Company accounts for its long-duration insurance contracts. Below is a summary of the impact of adopting ASU 2018-12:

•For the liability for future policy benefits, the net transition adjustment recorded in accumulated other comprehensive income (loss) is related to the difference in the discount rate used prior to the adoption of ASU 2018-12 and the discount rate at January 1, 2021, and the removal of shadow adjustments previously recorded in accumulated other comprehensive income (loss) for the impact of unrealized gains and losses that were included in the expected gross profits amortization calculation as of the transition date of $8,593 million, pretax.

•At transition, the Company identified certain cohorts in its Traditional segments where the present value of future expected benefits and expenses exceeded the sum of existing benefit reserve and the present value of future gross premiums, resulting in a decrease to retained earnings, net of reinsurance (and a corresponding increase in the liabilities for future policy benefits and reinsurance recoverable) of approximately $1,462 million, pretax. See “Impact of Adoption by Segment” for the transition impact by reportable segment.

•At transition, the Company identified certain cohorts, primarily longevity swaps, where the present value of future premiums exceeded the present value of future benefits resulting in a negative liability. The elimination of the negative liability at transition resulted in a decrease to retained earnings (and a corresponding increase in the liabilities for

future policy benefits) of $284 million, pretax. See “Impact of Adoption by Segment” for the transition impact by reportable segment.

•For DAC, the Company removed shadow adjustments previously recorded in AOCI in the amount of $114 million, pretax, for the impact of unrealized gains and losses that were included in the pre-ASU 2018-12 expected gross profits amortization calculation as of the transition date. See “Impact of Adoption by Segment” for the transition impact by reportable segment.

•For market risk benefits, the transition adjustment of $45 million, pretax, recognized in AOCI relates to the cumulative effect of changes in the instrument-specific credit risk between contract issue date and transition date. The remaining difference of $(72) million, pretax between the fair value and carrying value of the market risk benefits at transition, excluding the amounts recorded in AOCI, was recorded as an adjustment to retained earnings as of the transition date. See “Impact of Adoption by Segment” for the transition impact by reportable segment.

Income Tax Disclosure [Abstract]

Income Tax

INCOME TAX

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 2023 and is currently evaluating the likelihood that it will be an applicable corporation in 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 EUR 750 million or more. The Company established no net deferred taxes as a result of the enactment. The tax regime is effective for fiscal years beginning on or after January 1, 2025. The Company is still evaluating the impact of the newly enacted Bermuda corporate income tax regime on our financial position.

The Organization for Economic Cooperation and Development 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 EUR 750 million pay at least an effective tax rate of 15% on income arising in each jurisdiction in which they operate. The GloBE model rules serve as a template to allow for each jurisdiction to modify and incorporate into domestic law. As of December 31, 2023, many of the jurisdictions in which RGA operates enacted Pillar II legislation into domestic law with an effective date of January 1, 2024. Guidance is expected to continue throughout 2024 and beyond. The Company continues to evaluate the expected impact of the new law.

Pre-tax income for the years ended December 31, 2023, 2022 and 2021 consists of the following (dollars in millions):


	2023		2022		2021
Pre-tax income – U.S.	$	898	$	294	$	1,112

The provision for income tax expense for the years ended December 31, 2023, 2022 and 2021 consists of the following (dollars in millions):

Foreign	(25)		35		34
Total deferred	211		67		53
Total provision for income taxes	$	251	$	197	$	215

The effective tax rate for 2023 was slightly 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 effective tax rate for 2022 was higher than the U.S. Statutory rate of 21% primarily as a result of income in jurisdictions with tax rates differing from the U.S., Subpart F income and Global Intangible Low-Taxed income. These expenses were offset with benefits from foreign tax credits and return to provision adjustments.

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.

As of December 31, 2022, the valuation allowance against deferred tax assets was $235 million. During 2022, the Company established a $25 million valuation allowance on certain unrealized losses in the Company’s fixed maturity portfolio due to limitations on the utilization of the deferred tax asset. Additionally, there were 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 pretax earnings in certain subsidiaries with valuation allowances and foreign currency translation.

The earnings of substantially all of the Company's foreign subsidiaries have been permanently reinvested in foreign operations. The Company has provided a deferred tax liability for the future expected tax on foreign subsidiaries where the Company cannot assert permanent reinvestment. At December 31, 2023 and 2022, the financial reporting basis in excess of the tax basis for which no deferred taxes have been recognized was approximately $1.7 billion and $1.5 billion, respectively. As 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 2023, 2022 and 2021, the Company received federal and foreign income tax refunds of approximately $13 million, $3 million and $20 million, respectively. The Company made cash income tax payments of approximately $311 million, $131 million and $388 million, in 2023, 2022 and 2021, respectively.

The following table presents consolidated net operating loss carryforwards (“NOL”) as of December 31, 2023 (dollars in millions):


	2023
NOL with no expiration and with no valuation allowance	$	423
NOL with a full valuation allowance	126
NOL with no expiration and a partial valuation allowance	505
NOL with expiration date of 2034 and no valuation allowance	12
Total net operating loss carryforwards	$	1,066

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, 2023, the Company had foreign tax credit carryforwards of $108 million related to the U.S. and Ireland. The earliest year of expiration on the U.S. foreign tax credits is 2029. 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. Furthermore, the Company established anticipatory future foreign tax credits to offset Bermuda deferred tax liabilities established upon enactment of the Bermuda Income Tax.

The Company files income tax returns in the U.S. federal jurisdiction and various state and foreign jurisdictions. The income tax years under examination vary by jurisdiction, but tax years 2020, 2021 and 2022 are generally subject to examination by the tax authorities. The Company is no longer subject to U.S. federal income tax examinations by tax authorities for years prior to 2020, Canadian tax authorities for years prior to 2018 and with a few exceptions, the Company is no longer subject to state and foreign income tax examinations by tax authorities for years prior to 2019.

As of December 31, 2023, 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 $3 million over the next 12 months if statutes expire.

A reconciliation of the beginning and ending amount of unrecognized tax benefits for the years ended December 31, 2023, 2022 and 2021 is as follows (dollars in millions):


	Total Unrecognized Tax Benefits
	2023		2022		2021
Beginning balance, January 1	$	36	$	34	$	342

Additions for tax positions of prior years	9		3		2
Reductions for tax positions of prior years	(15)		(4)		(312)
Additions for tax positions of current year	3		3		2


Ending balance, December 31	$	33	$	36	$	34

The Company recognized minimal interest expense (benefit) associated with uncertain tax positions in 2023 and 2022 and $(31) million in 2021. As of December 31, 2023 and 2022, 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, 2023 or 2022.

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

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, premiums receivable, future policy benefits, incurred but not reported claims, income taxes, valuation of investments and investment impairments, and 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. Standards Issued and Implemented In the first quarter of 2023, the Company adopted Accounting Standards Update (“ASU”): ASU 2018-12, Financial Services – Insurance (Topic 944): Targeted Improvements to the Accounting for Long-Duration Contracts (“ASU 2018-12”). ASU 2018-12 updates certain requirements for the accounting for long-duration insurance contracts. •Cash flow assumptions and measuring liability for future policy benefits – ASU 2018-12 requires the Company to review its cash flow assumptions at least annually and update, if necessary, with the impact recognized in net income in the period of the change. The liability for future policy benefits includes required adjustments at the cohort level to cap the net premium ratio at 100% and eliminate negative reserves. Upon adoption, an adjustment was recorded to retained earnings as a result of capping the net premium ratio at 100% and eliminating negative reserves on certain issue year cohorts. •Discount rate – The discount rate assumption is prescribed by ASU 2018-12 as an upper-medium (low credit risk) fixed-income yield and is required to be updated every quarter. The change in the liability as a result of updating the discount rate assumption is recognized in other comprehensive income (loss) (“OCI”). Upon adoption, an adjustment was recorded to accumulated other comprehensive income (loss) (“AOCI”) as a result of remeasuring in force contract liabilities using the current upper-medium grade fixed income instrument yields as of the date of transition. The adjustment reflects the difference between discount rates locked-in at contract inception versus current discount rates at transition. •Deferred policy acquisition costs and similar balances – Deferred policy acquisition costs (“DAC”) and other capitalized costs such as unearned revenue should be amortized on a constant level or straight-line basis over the expected term of the contracts. Upon adoption, an adjustment was recorded to AOCI for the removal of cumulative adjustments to DAC associated with unrealized investment gains and losses previously recorded in accumulated other comprehensive income (loss). •Market risk benefits – Market risk benefits, which are contracts or contract features that provide protection to the policyholder from capital market risk and expose the Company to other-than-nominal capital market risk, are measured at fair value. The periodic change in fair value is recognized in net income with the exception of the periodic change in fair value related to the liability’s instrument-specific credit risk, which is recognized in OCI. Upon adoption, an adjustment was recorded to retained earnings for the difference between the fair value and carrying value of the contracts at the transition date, excluding changes in the instrument-specific credit risks, and an adjustment to AOCI for the cumulative effect of changes in the instrument-specific credit risk between contract issue date and transition date.

The Company enters into various collateral arrangements with counterparties that require both the pledging and acceptance of fixed maturity securities as collateral. Pledged fixed maturity securities are included in fixed maturity securities, available-for-sale in the consolidated balance sheets. Fixed maturity securities received as collateral are held in separate custodial accounts and are not recorded on the Company’s 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, 2023 and 2022, none of the collateral received had been sold or repledged. The Company also holds assets in trust to satisfy collateral requirements under derivative transactions and certain third-party reinsurance treaties. The following table includes fixed maturity securities pledged and received as collateral and assets in trust held to satisfy collateral requirements under derivative transactions and certain third-party reinsurance treaties as of December 31, 2023 and 2022 (dollars in millions):

Allowance for Credit Losses and Impairments – Fixed Maturity Securities Available-for-Sale

As discussed in Note 2 – “Significant Accounting Policies and Pronouncements,” allowances for credit losses on fixed maturity securities are recognized in investment related gains (losses), net. The amount recognized represents the difference between the amortized cost of the security and the net present value of its projected future cash flows discounted at the effective interest rate implicit in the fixed maturity security prior to the allowance for credit losses. Any remaining difference between the fair value and amortized cost is recognized in OCI.

The following tables present the rollforward of the allowance for credit losses in fixed maturity securities by type for the years ended December 31, 2023 and 2022 (dollars in millions):

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 5,788 and 6,441 fixed maturity securities for which an allowance for credit loss has not been recorded as of December 31, 2023 and December 31, 2022, and the estimated fair value had declined and remained below amortized cost (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.

The Company did not intend to sell, and more likely than not would not be required to sell, the securities outlined in the tables above, as of the dates indicated. 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.

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 $7 million on nonaccrual status as of December 31, 2023. The Company had two mortgage loans in the amount of $36 million that were on nonaccrual status as of December 31, 2022. During 2023, the Company converted three mortgage loans totaling $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 2023, 2022 and 2021.

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, 2023, $3.3 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, 2023 and 2022 are as follows (dollars in millions):

Accounting Policies [Abstract]

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, premiums receivable, future policy benefits, incurred but not reported claims, income taxes, valuation of investments and investment impairments, and 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.

Standards Issued and Implemented

In the first quarter of 2023, the Company adopted Accounting Standards Update (“ASU”): ASU 2018-12, Financial Services – Insurance (Topic 944): Targeted Improvements to the Accounting for Long-Duration Contracts (“ASU 2018-12”). ASU 2018-12 updates certain requirements for the accounting for long-duration insurance contracts.

•Cash flow assumptions and measuring liability for future policy benefits – ASU 2018-12 requires the Company to review its cash flow assumptions at least annually and update, if necessary, with the impact recognized in net income in the period of the change. The liability for future policy benefits includes required adjustments at the cohort level to cap the net premium ratio at 100% and eliminate negative reserves.

Upon adoption, an adjustment was recorded to retained earnings as a result of capping the net premium ratio at 100% and eliminating negative reserves on certain issue year cohorts.

•Discount rate – The discount rate assumption is prescribed by ASU 2018-12 as an upper-medium (low credit risk) fixed-income yield and is required to be updated every quarter. The change in the liability as a result of updating the discount rate assumption is recognized in other comprehensive income (loss) (“OCI”).

Upon adoption, an adjustment was recorded to accumulated other comprehensive income (loss) (“AOCI”) as a result of remeasuring in force contract liabilities using the current upper-medium grade fixed income instrument yields as of

the date of transition. The adjustment reflects the difference between discount rates locked-in at contract inception versus current discount rates at transition.

•Deferred policy acquisition costs and similar balances – Deferred policy acquisition costs (“DAC”) and other capitalized costs such as unearned revenue should be amortized on a constant level or straight-line basis over the expected term of the contracts.

Upon adoption, an adjustment was recorded to AOCI for the removal of cumulative adjustments to DAC associated with unrealized investment gains and losses previously recorded in accumulated other comprehensive income (loss).

•Market risk benefits – Market risk benefits, which are contracts or contract features that provide protection to the policyholder from capital market risk and expose the Company to other-than-nominal capital market risk, are measured at fair value. The periodic change in fair value is recognized in net income with the exception of the periodic change in fair value related to the liability’s instrument-specific credit risk, which is recognized in OCI.

Upon adoption, an adjustment was recorded to retained earnings for the difference between the fair value and carrying value of the contracts at the transition date, excluding changes in the instrument-specific credit risks, and an adjustment to AOCI for the cumulative effect of changes in the instrument-specific credit risk between contract issue date and transition date.

Change in Certain Segment Allocations

Investment income for each segment has been adjusted to reflect the impacts of adopting ASU 2018-12 and due to an update to the Company’s internally developed economic capital model. Internal excess capital charges, included in each segment’s policy acquisition costs and other insurance expenses, were also updated as a result of adopting ASU 2018-12 and updates to the Company’s internally developed economic capital model. These changes did not impact the recognition or presentation of investment income or policy acquisition costs and other insurance expenses in the consolidated financial statements.

•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

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.
