Insurance [Abstract]
Future Policy Benefits	Future policy benefits primarily include reserves for traditional life and annuity payout contracts, which represent an estimate of the present value of future benefits less the present value of future net premiums. Included in Future policy benefits are liabilities for annuities issued in structured settlement arrangements whereby a claimant receives life contingent payments over their lifetime. Also included are pension risk transfer arrangements whereby an upfront premium is received in exchange for guaranteed retirement benefits. All payments under these arrangements are fixed and determinable with respect to their amounts and dates. Structured settlement or other annuitization elections (e.g., certain single premium immediate annuities) that do not involve life contingent payments, but rather payments for a stated period are included in Policyholder contract deposits. For traditional and limited pay long-duration products, benefit reserves are accrued and benefit expense is recognized using a net premium ratio (“NPR”) methodology for each annual cohort of business. This NPR method incorporates periodic retrospective revisions to the NPR to reflect updated actuarial assumptions and variances in actual versus expected experience. The Future policy benefit liability is accrued by multiplying the gross premium recognized in each period by the NPR. The net premium is equal to the portion of the gross premium required to provide for all benefits and certain expenses and may not exceed 100%. Benefits in excess of premiums are expensed immediately through policyholder benefits. In addition, periodic revisions to the NPR below 100% may result in reclassification between the benefit reserves and deferred profit liability for limited pay contracts. Insurance contracts are aggregated into annual cohorts for the purposes of determining the liability for future policy benefits (“LFPB”), but are not aggregated across segments. These annual cohorts may be further segregated based on product characteristics, or to distinguish business reinsured from non-reinsured business or products issued in different functional currencies. The assumptions used to calculate the future policy benefits include discount rates, persistency and recognized morbidity and mortality tables modified to reflect the Company's experience. The current discount rate assumption for the liability for future policy benefits is derived from market observable yields on upper-medium-grade fixed income instruments. The Company uses an external index as the source of the yields on these instruments for the first 30 years. For years 30 to 50, the yield is derived using market observable yields. Yields for years 50 to 100 are extrapolated using a flat forward approach, maintaining a constant forward spread through the period. The current discount rate assumption is updated quarterly and used to remeasure the liability at the reporting date, with the resulting change in the discount rate reflected in OCI. The method for constructing and applying the locked-in discount rate assumptions on newly issued business is determined based on factors such as product characteristics and the expected timing of cash flows. This discount rate assumption is derived from market observable yields on upper-medium-grade fixed income instruments. Similar to the current discount rate assumption, the Company may employ conversion and interpolation methodologies when necessary. The applicable interest accretion is reflected in policyholder benefits in the Consolidated Statements of Income (Loss). Deferred Profit Liability: Corebridge issues certain annuity and life insurance contracts where premiums are paid up-front or for a shorter period than benefits will be paid (i.e., limited pay contracts). A Deferred Profit Liability (“DPL”) is required to be established to avoid recognition of gains when these contracts are issued. DPLs are amortized over the life of the contracts to align the revenue recognized with the related benefit expenses. The difference between the gross premium received and recorded as revenue and the net premium is deferred and recognized in policyholder benefits in a constant relationship to insurance in-force, or for annuities, the amount of expected future policy benefits. This deferred profit liability accretes interest and is recorded in the Consolidated Balance Sheets in Future policy benefits. Cash flow assumptions included in the measurement of the DPL are the same as those utilized in the respective LFPBs and are reviewed at least annually. The cash flow estimates for DPLs are updated on a retrospective catch-up basis at the same time as the cash flow estimates for the related LFPBs. The updated LFPB cash flows are used to recalculate the DPL at the inception of the applicable related LFPB cohort. The difference between the recalculated DPL at the beginning of the current reporting period and the carrying amount of the DPL at the current reporting period is recognized as a gain or loss in policyholder benefits in the Consolidated Statements of Income (Loss).
