Fair Value Disclosures [Abstract]  
Fair Value of Assets and Liabilities FAIR VALUE OF ASSETS AND LIABILITIES
Fair Value Measurement - Fair value represents the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The authoritative fair value guidance establishes a framework for measuring fair value that includes a hierarchy used to classify the inputs used in measuring fair value. The level in the fair value hierarchy within which the fair value measurement falls is determined based on the lowest level input that is significant to the fair value measurement. The levels of the fair value hierarchy are as follows:

Level 1 Fair value is based on unadjusted quoted prices in active markets that are accessible to the Company for identical assets or liabilities.

Level 2 Fair value is based on significant inputs, other than quoted prices included in Level 1, that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability through corroboration with observable market data. Level 2 inputs include quoted market prices in active markets for similar assets and liabilities, quoted market prices in markets that are not active for identical or similar assets or liabilities, and other market observable inputs.

Level 3 Fair value is based on at least one significant unobservable input for the asset or liability. The assets and liabilities in this category may require significant judgment or estimation in determining the fair value.

For a discussion of the Company's valuation methodologies for assets and liabilities measured at fair value and the fair value hierarchy, see Note 5 to the Consolidated Financial Statements included in the Company’s restated Consolidated Financial Statements for the year ended December 31, 2022 included as Exhibit 99.1 within the Company's Current Report on Form 8-K filed on July 14, 2023.

As a result of the adoption of ASU 2018-12 in the first quarter of 2023, the Company is required to measure all market risk benefits (e.g., living benefit and death benefit guarantees associated with variable annuities) at fair value. Market risk benefit liabilities (or assets) represent contracts or contract features that provide protection to the contractholder and exposes the Company to other than nominal capital market risk, primarily related to deferred annuities with guaranteed minimum benefits in the annuities products including GMDB, GMIB, GMAB, GMWB and GMIWB. The benefits are bundled together and accounted for as single compound market risk benefits using a fair value measurement framework.
The fair value of these market risk benefits is calculated as the present value of expected future benefit payments to contractholders less the present value of expected future rider fees attributable to the market risk benefit. The fair value of these benefit features is based on assumptions a market participant would use in valuing market risk benefits. This methodology could result in either a liability or asset balance, given changing capital market conditions and various actuarial assumptions. Since there is no observable active market for the transfer of these obligations, the valuations are calculated using internally-developed models with option pricing techniques. The models are based on a risk neutral valuation framework and incorporate premiums for risks inherent in valuation techniques, inputs, and the general uncertainty around the timing and amount of future cash flows. The determination of these risk premiums requires the use of management’s judgment.

The significant inputs to the valuation models for these market risk benefits include capital market assumptions, such as interest rate levels and volatility assumptions, the Company’s market-perceived NPR, as well as actuarially determined assumptions, including contractholder behavior, such as lapse rates, benefit utilization rates, withdrawal rates, and mortality rates. Since many of these assumptions are unobservable and are considered to be significant inputs to the valuations, the assets and liabilities included in market risk benefits have been reflected within Level 3 in the fair value hierarchy.

Capital market inputs and actual policyholders’ account values are updated each quarter based on capital market conditions as of the end of the quarter, including interest rates, equity markets and volatility. In the risk neutral valuation, the initial swap curve drives the total return used to grow the policyholders’ account values. The Company’s discount rate assumption is based on the SOFR swap curve adjusted for an additional spread relative to SOFR to reflect the Company’s market-perceived NPR, which is the risk that the obligation will not be fulfilled by the Company. NPR is primarily estimated by utilizing the credit spreads associated with the Company issued funding agreements, adjusted for any illiquidity risk premium. In order to reflect the financial strength ratings of the Company, credit spreads associated with funding agreements, as opposed to credit spread associated with debt, are utilized in developing this estimate because funding agreements are insurance liabilities and are therefore senior to debt.

Actuarial assumptions, including contractholder behavior and mortality, are reviewed at least annually, and updated based upon company emerging experience and industry studies, future expectations and other data, including any observable market data. These assumptions are generally updated annually unless a material change that the Company feels is indicative of a long-term trend is observed in an interim period. See "Annual Assumptions Review" in Note 2 for additional information.

(1)“Netting” amounts represent cash collateral of $(9,595) million and $(8,931) million as of September 30, 2023 and December 31, 2022, respectively.
(2)Includes credit-tranched securities collateralized by syndicated bank loans, sub-prime mortgages, auto loans, credit cards, education loans and other asset types.
(3)Other invested assets excluded from the fair value hierarchy include certain hedge funds, private equity funds and other funds for which fair value is measured at net asset value ("NAV") per share (or its equivalent) as a practical expedient. As of September 30, 2023 and December 31, 2022, the fair values of such investments were $65 million and $69 million, respectively.
(4)Separate account assets represent segregated funds that are invested for certain customers. Investment risks associated with market value changes are borne by the customers, except to the extent of minimum guarantees made by the Company with respect to certain accounts. Separate account liabilities are not included in the above table as they are reported at contract value and not fair value in the Company's Unaudited Interim Consolidated Statements of Financial Position.
(5)Separate account assets included in the fair value hierarchy exclude investments in entities that calculate NAV per share (or its equivalent) as a practical expedient. Such investments excluded from the fair value hierarchy include investments in real estate, hedge funds and a corporate owned life insurance fund, for which fair value is measured at NAV per share (or its equivalent). At September 30, 2023 and December 31, 2022, the fair value of such investments were $4,957 million and $5,262 million, respectively.

(1)Conversely, the impact of a decrease in input would have the opposite impact on fair value as that presented in the table.
(2)Includes assets classified as fixed maturities, available-for-sale.
(3)Represents multiples of earnings before interest, taxes, depreciation and amortization ("EBITDA"), and are amounts used when the Company has determined that market participants would use such multiples when valuing the investments.
(4)Market risk benefits primarily represent fair value for all living benefit guarantees including accumulation, withdrawal and income benefits. Since the valuation methodology for these assets and liabilities uses a range of inputs that vary at the contract level over the cash flow projection period, presenting a range, rather than weighted average, is a more meaningful representation of the unobservable inputs used in the valuation.
(5)Lapse rates for contracts with living benefit guarantees are adjusted at the contract level based on the in-the-moneyness of the living benefit and reflect other factors, such as the applicability of any surrender charges. Lapse rates are reduced when contracts are more in-the-money. Lapse rates for contracts with index-linked crediting guarantees may be adjusted at the contract level based on the applicability of any surrender charges, product type, and market related factors such as interest rates. Lapse rates are also generally assumed to be lower for the period where surrender charges apply. For any given contract, lapse rates vary throughout the period over which cash flows are projected for the purposes of valuing these embedded derivatives.
(6)The spread over the Secured Overnight Financing Rate (“SOFR”) swap curve and the London Inter-Bank Offered Rate (“LIBOR”) swap curve represents the premium added to the proxy for the risk-free rate (SOFR or LIBOR, as applicable) to reflect the Company’s estimates of rates that a market participant would use to value the living benefits in both the accumulation and payout phases and index-linked interest crediting guarantees as of September 30, 2023 and December 31, 2022, respectively. This spread includes an estimate of NPR, which is the risk that the obligation will not be fulfilled by the Company. NPR is primarily estimated by utilizing the credit spreads associated with issuing funding agreements, adjusted for any illiquidity risk premium. In order to reflect the financial strength ratings of the Company, credit spreads associated with funding agreements, as opposed to credit spread associated with debt, are utilized in developing this estimate because funding agreements are insurance liabilities and are therefore senior to debt. Effective April 2023, the Company entered into an agreement with The Ohio National Life Insurance Company ("Ohio National"), an affiliate of Constellation Insurance Holdings, Inc., to reinsure approximately $10 billion of account values of PDI traditional variable annuity contracts with guaranteed living benefits. See Note 11 for additional information regarding this transaction. As a result of this transaction, a ceded MRB asset balance was established to fair value the reinsurance reimbursements to the Company. The establishment of the fair value also required an estimate of NPR for Ohio National, which may differ from that of the Company's; however, the NPR spreads for Ohio National were developed using a methodology similar to that of the Company.
(7)The utilization rate assumption estimates the percentage of contracts that will utilize the benefit during the contract duration and begin lifetime withdrawals at various time intervals from contract inception. The remaining contractholders are assumed to either begin lifetime withdrawals immediately or never utilize the benefit. Utilization assumptions may vary by product type, tax status and age. The impact of changes in these assumptions is highly dependent on the product type, the age of the contractholder at the time of the sale, and the timing of the first lifetime income withdrawal. Range reflects the utilization rate for the vast majority of business with living benefits.
(8)The withdrawal rate assumption estimates the magnitude of annual contractholder withdrawals relative to the maximum allowable amount under the contract. These assumptions vary based on the age of the contractholder, the tax status of the contract and the duration since the contractholder began lifetime withdrawals. As of September 30, 2023 and December 31, 2022, the minimum withdrawal rate assumption is 81% and 77%, respectively. As of September 30, 2023 and December 31, 2022, the maximum withdrawal rate assumption may be greater than 100%. The fair value of the liability will generally increase the closer the withdrawal rate is to 100% and decrease as the withdrawal rate moves further away from 100%.
(9)The range reflects the mortality rates for the vast majority of business with living benefits and other contracts, with policyholders ranging from 50 to 90 years old. While the majority of living benefits have a minimum age requirement, certain other contracts do not have an age restriction. This results in contractholders with mortality rates approaching 0% for certain benefits. Mortality rates may vary by product, age, and duration. A mortality improvement assumption is also incorporated into the overall mortality table.
(10)Policyholders’ account balances primarily represent general account liabilities for the index-linked interest credited on certain of the Company’s life and annuity products that are accounted for as embedded derivatives. Since the valuation methodology for these liabilities uses a range of inputs that vary at the contract level over the cash flow projection period, presenting a range, rather than weighted average, is a more meaningful representation of the unobservable inputs used in the valuation.
(11)Option budget estimates the expected long-term cost of options used to hedge exposures associated with equity price and interest rate changes. The level of option budgets determines future costs of the options, which impacts the growth in account value and the valuation of embedded derivatives.

Interrelationships Between Unobservable Inputs In addition to the sensitivities of fair value measurements to changes in each unobservable input in isolation, as reflected in the table above, interrelationships between these inputs may also exist, such that a change in one unobservable input may give rise to a change in another or multiple inputs. Examples of such interrelationships for significant internally-priced Level 3 assets and liabilities are as follows:

Corporate Securities – The rate used to discount future cash flows reflects current risk-free rates plus credit and liquidity spread requirements that market participants would use to value an asset. The discount rate may be influenced by many factors, including market cycles, expectations of default, collateral, term, and asset complexity. Each of these factors can influence discount rates, either in isolation, or in response to other factors. During weaker economic cycles, as the expectations of default increases, credit spreads widen, which results in a decrease in fair value.

Market Risk Benefits – The Company expects efficient benefit utilization and withdrawal rates to generally be correlated with lapse rates. However, behavior is generally highly dependent on the facts and circumstances surrounding the individual contractholder, such as their liquidity needs or tax situation, which could drive lapse behavior independent of other contractholder behavior assumptions. To the extent more efficient contractholder behavior results in greater in-the-moneyness at the contract level, lapse rates may decline for those contracts. Similarly, to the extent that increases in equity volatility are correlated with overall declines in the capital markets, lapse rates may decline as contracts become more in-the-money.

Changes in Level 3 Assets and Liabilities The following tables describe changes in fair values of Level 3 assets and liabilities as of the dates indicated, as well as the portion of gains or losses included in income attributable to unrealized gains or losses related to those assets and liabilities still held at the end of their respective periods (excluding MRBs disclosed in Note 10). When a determination is made to classify assets and liabilities within Level 3, the determination is based on significance of the unobservable inputs in the overall fair value measurement. All transfers are based on changes in the observability of the valuation inputs, including the availability of pricing service information that the Company can validate. Transfers into Level 3 are generally the result of unobservable inputs utilized within valuation methodologies and the use of indicative broker quotes for assets that were previously valued using observable inputs. Transfers out of Level 3 are generally due to the use of observable inputs in valuation methodologies as well as the availability of pricing service information for certain assets that the Company can validate.

Nonrecurring Fair Value Measurements – The following tables represent information for assets measured at fair value on a nonrecurring basis. The fair value measurement is nonrecurring as these assets are measured at fair value only when there is a triggering event (e.g., an evidence of impairment). Assets included in the table are those that were impaired during the respective reporting periods and that are still held as of the reporting date. The estimated fair values for these amounts were determined using significant unobservable inputs (Level 3). For both the three and nine months ended September 30, 2023, there were no triggering events.
