(1)“Netting” amounts represent cash collateral of $(9,569) million and $(8,931) million as of December 31, 2023 and 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)Equity securities excluded from the fair value hierarchy include a fund for which fair value is measured at net asset value ("NAV") per share (or its equivalent) as a practical expedient. As of December 31, 2023, the fair value of this investment was $14.6 million.
(4)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 NAV per share (or its equivalent) as a practical expedient. At December 31, 2023 and 2022, the fair values of such investments were $67 million and $69 million, respectively.
(5)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 Consolidated Statements of Financial Position.
(6)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 December 31, 2023 and 2022, the fair value of such investments was $5,259 million and $5,262 million, respectively.
(7)Other liabilities includes embedded derivatives associated with reinsurance agreements.
(8)Amounts reflect the implementation of ASU 2018-12: Targeted Improvements to the Accounting for Long-Duration Contracts.

(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 balances.
(6)The spread over the SOFR swap curve and the 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 December 31, 2023 and 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, now known as AuguStar Life Insurance Company ("AuguStar"), 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 AuguStar, which may differ from that of the Company's; however, the NPR spreads for AuguStar 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 December 31, 2023 and 2022, the minimum withdrawal rate assumption is 81% and 77%, respectively. As of December 31, 2023 and 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 budget determines future costs of the options, which impacts the growth in account value and the valuation of embedded derivatives.
(12)Amounts reflect the implementation of ASU 2018-12: Targeted Improvements to the Accounting for Long-Duration Contracts.
Fair Value, Assets Measured on Recurring Basis, Unobservable Input Reconciliation 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.

Fair Value Measurements, Nonrecurring 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 the years ended December 31, 2023 and 2021, there were no triggering events.
