New Accounting Standards (Policies)	3 Months Ended
Mar. 31, 2023
Accounting Policies [Abstract]
Basis of Presentation	The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial information. Accordingly, certain financial information that is normally included in annual financial statements prepared in accordance with U.S. GAAP, but not required for interim reporting purposes, has been condensed or omitted. These Condensed Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements and the related notes included in our Annual Report on Form 10-K for the year ended December 31, 2022, as filed with the SEC on March 1, 2023, (the "2022 Annual Report"). The condensed consolidated financial information as of December 31, 2022, included herein, has been derived from the audited Consolidated Financial Statements in the 2022 Annual Report, but recast, as described in these notes, to reflect the adoption of the accounting standard discussed in the next paragraph. The Company adopted Accounting Standards Update (“ASU”) 2018-12, “Targeted Improvements to the Accounting for Long-Duration Contracts,” (“LDTI”) effective January 1, 2023, with a transition date of January 1, 2021. See Note 2 of the Notes to Condensed Consolidated Financial Statements for further description of the adoption of LDTI. Certain accounting policies, which significantly affect the determination of financial condition, results of operations and cash flows, are summarized in the Notes to Consolidated Financial Statements in the Company’s 2022 Annual Report. New accounting policies adopted for LDTI are included in the Notes 7, 8, 9, 10, 11, and 12 to the Condensed Consolidated Financial Statements in this Form 10-Q. In the opinion of management, these financial statements include all normal recurring adjustments necessary for a fair presentation of the Company’s results. Operating results for the three months ended March 31, 2023, are not necessarily indicative of the results that may be expected for the full year ending December 31, 2023.
Consolidation	All material intercompany accounts and transactions have been eliminated in consolidation.
Use of Estimates	The preparation of the Condensed Consolidated Financial Statements in conformity with U.S. GAAP requires the use of estimates and assumptions about future events that affect the amounts reported in the Condensed Consolidated Financial Statements and the accompanying notes. Significant estimates or assumptions, as further discussed in the notes, include: •Valuation of investments and derivative instruments, including fair values of securities deemed to be in an illiquid market and the determination of when an impairment is necessary; •Assessments as to whether certain entities are VIEs, the existence of reconsideration events and the determination of which party, if any, should consolidate the entity; •Assumptions used in calculating policy reserves and liabilities including policyholder behavior, mortality rates, expenses, investment returns and policy crediting rates; •Assumptions as to future earnings levels being sufficient to realize deferred tax benefits; •Estimates related to expectations of credit losses on certain financial assets and off-balance sheet exposures; •Assumptions and estimates associated with the Company’s tax positions, including an estimate of the dividends received deduction, which impact the amount of recognized tax benefits recorded by the Company; •Assumptions used in calculating market risk benefits including policyholder behavior, mortality rates, and capital market assumptions; •Assumptions impacting the expected term used in the calculation of amortization of deferred acquisition costs, including policyholder behavior and mortality rates. These estimates and assumptions are based on management’s best estimates and judgments. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors deemed appropriate. As facts and circumstances dictate, these estimates and assumptions may be adjusted. Since future events and their effects cannot be determined with precision, actual results could differ significantly from these estimates. Changes in estimates, including those resulting from continuing changes in the economic environment, will be reflected in the consolidated financial statements in the periods the estimates are changed.
Revision of Prior Period Financial Statements	In 2022, the Company identified errors related to the classification of certain balances and amounts in the line items of the Condensed Consolidated Balance Sheets and Condensed Consolidated Income Statements. These errors resulted in the revision of balances and amounts related to deferred sales inducement assets, liabilities for certain life-contingent annuities, sub-advisor fee expenses, and other operating expense items that impacted previously issued Condensed Consolidated Financial Statements. The impact of these errors to the prior periods' Condensed Consolidated Financial Statements were not considered to be material and had no impact on shareholders' equity or net income (loss). However, to improve the consistency and comparability of the financial statements, management revised the financial statements and related disclosures in this quarterly report. See Note 22 to the Notes to Condensed Consolidated Financial Statements for details of the revisions.
New Accounting Standards	Changes in Accounting Principles – Adopted in Current Year In March 2020, the Financial Accounting Standards Board (“FASB”) issued ASU 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting.” The new guidance provides optional expedients for applying U.S. GAAP to contracts and other transactions affected by reference rate reform and is effective for contract modifications made between March 12, 2020 and December 31, 2022. If certain criteria are met, an entity will not be required to remeasure or reassess contracts impacted by reference rate reform. The practical expedient allowed by this standard was elected and is being applied prospectively by the Company as reference rate reform unfolds. The contracts modified to date met the criteria for the practical expedient and therefore had no material impact on the Company’s Condensed Consolidated Financial Statements. In December 2022, the FASB issued ASU 2022-06, “Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848” which defers the sunset date of Topic 848 from December 31, 2022 to December 31, 2024, after which entities will no longer be permitted to apply the relief in Topic 848. The amendments are effective for all entities as of December 21, 2022. The Company will continue to evaluate the impacts of reference rate reform on contract modifications and other transactions through December 31, 2024. In August 2018, the FASB issued ASU 2018-12, “Targeted Improvements to the Accounting for Long Duration Contracts,” ("LDTI"), which included changes to the existing recognition, measurement, presentation and disclosure requirements for long-duration contracts issued by an insurance entity. The Company adopted LDTI effective January 1, 2023, with a transition date of January 1, 2021, using the modified retrospective transition method relating to liabilities for traditional and limited payment contracts and deferred policy acquisition costs associated therewith, and on a retrospective basis, in relation to market risk benefits ("MRBs"). Under the modified retrospective approach, the Company applied the guidance to contracts in force on the transition date on the basis of their existing carrying value, using updated future cash flow assumptions, and eliminated certain related amounts in accumulated other comprehensive income (loss) (“AOCI”). Under the full retrospective transition approach, the Company applied the guidance as of the transition date, using actual historical assumption information as of contract inception, as if the accounting principle had always been applied. Amounts reported as of March 31, 2023 and December 31, 2022 and for the three months ended March 31, 2023 and 2022 within these Condensed Consolidated Financial Statements are accounted for and presented in accordance with U.S. GAAP reflecting the adoption of LDTI. LDTI contains four significant changes: 1.Market risk benefits: market risk benefits, a new term for certain contract features that provide for potential benefits in addition to the account balance that expose the Company to other-than-nominal market risk (for example, guaranteed benefits on annuity contracts, including guaranteed minimum withdrawal benefits and guaranteed minimum death benefits on variable annuities), are measured at fair value. Changes in fair value are recorded and presented separately within the income statement, with the exception of changes in fair value due to non-performance risk, which are recognized in other comprehensive income (loss) (“OCI”); 2.Deferred acquisition costs: deferred acquisition costs (“DAC”) are amortized on a constant-level basis, independent of profitability of the underlying business; 3.Liability for future policy benefits: annual review and, if necessary, update of cash flow assumptions used to measure the liability for future policy benefits for nonparticipating traditional and limited-payment insurance contracts is required. These liabilities are discounted using an upper-medium grade fixed income instrument yield which is updated quarterly, with related changes in the liability recognized in OCI; and 4.Enhanced disclosures: enhanced disclosures, including disaggregated roll-forwards of certain balance sheet accounts that provide information about actual and expected cash flows, as well as information about significant inputs, judgments, assumptions and methods used in measurement, are required. The enhanced disclosures are intended to improve the ability of users of the financial statements to evaluate the timing, amount, and uncertainty of cash flows arising from long-duration contracts. The adoption of LDTI resulted in a decrease in total equity of $3.0 billion as of the transition date of January 1, 2021, comprised of a reduction in AOCI of $0.4 billion and a reduction in retained earnings of $2.6 billion. The primary drivers for this impact to total equity included: 1.the classification of certain benefits as market risk benefits (“MRB”) which were remeasured at fair value as of the transition date. The resulting change in the value of these benefits at the transition date, net of the related deferred tax effect, is recognized in retained earnings, with the exception of the cumulative effect of changes in non-performance risk, net of the related deferred tax effect, which is recognized in AOCI; 2.changes to the discount rate used to measure liabilities for future policyholder benefits which, under LDTI, are remeasured each reporting period using current upper-medium grade fixed-income instrument yields, which are generally considered to be those on single-A rated public corporate debt. The cumulative effect of the remeasurement of these liabilities using the transition date discount rate, net of the related deferred tax effect, is recognized in AOCI; and

New Accounting Standards (Policies)

3 Months Ended

Mar. 31, 2023

The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial information. Accordingly, certain financial information that is normally included in annual financial statements prepared in accordance with U.S. GAAP, but not required for interim reporting purposes, has been condensed or omitted. These Condensed Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements and the related notes included in our Annual Report on Form 10-K for the year ended December 31, 2022, as filed with the SEC on March 1, 2023, (the "2022 Annual Report"). The condensed consolidated financial information as of December 31, 2022, included herein, has been derived from the audited Consolidated Financial Statements in the 2022 Annual Report, but recast, as described in these notes, to reflect the adoption of the accounting standard discussed in the next paragraph.

The Company adopted Accounting Standards Update (“ASU”) 2018-12, “Targeted Improvements to the Accounting for Long-Duration Contracts,” (“LDTI”) effective January 1, 2023, with a transition date of January 1, 2021. See Note 2 of the Notes to Condensed Consolidated Financial Statements for further description of the adoption of LDTI.

Certain accounting policies, which significantly affect the determination of financial condition, results of operations and cash flows, are summarized in the Notes to Consolidated Financial Statements in the Company’s 2022 Annual Report. New accounting policies adopted for LDTI are included in the Notes 7, 8, 9, 10, 11, and 12 to the Condensed Consolidated Financial Statements in this Form 10-Q.

In the opinion of management, these financial statements include all normal recurring adjustments necessary for a fair presentation of the Company’s results. Operating results for the three months ended March 31, 2023, are not necessarily indicative of the results that may be expected for the full year ending December 31, 2023.

Consolidation

All material intercompany accounts and transactions have been eliminated in consolidation.

Use of Estimates

The preparation of the Condensed Consolidated Financial Statements in conformity with U.S. GAAP requires the use of estimates and assumptions about future events that affect the amounts reported in the Condensed Consolidated Financial Statements and the accompanying notes. Significant estimates or assumptions, as further discussed in the notes, include:

•Valuation of investments and derivative instruments, including fair values of securities deemed to be in an illiquid market and the determination of when an impairment is necessary;

•Assessments as to whether certain entities are VIEs, the existence of reconsideration events and the determination of which party, if any, should consolidate the entity;

•Assumptions used in calculating policy reserves and liabilities including policyholder behavior, mortality rates, expenses, investment returns and policy crediting rates;

•Assumptions as to future earnings levels being sufficient to realize deferred tax benefits;

•Estimates related to expectations of credit losses on certain financial assets and off-balance sheet exposures;

•Assumptions and estimates associated with the Company’s tax positions, including an estimate of the dividends received deduction, which impact the amount of recognized tax benefits recorded by the Company;

•Assumptions used in calculating market risk benefits including policyholder behavior, mortality rates, and capital market assumptions;

•Assumptions impacting the expected term used in the calculation of amortization of deferred acquisition costs, including policyholder behavior and mortality rates.

These estimates and assumptions are based on management’s best estimates and judgments. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors deemed appropriate. As facts and circumstances dictate, these estimates and assumptions may be adjusted. Since future events and their effects cannot be determined with precision, actual results could differ significantly from these estimates. Changes in estimates, including those resulting from continuing changes in the economic environment, will be reflected in the consolidated financial statements in the periods the estimates are changed.

Revision of Prior Period Financial Statements

In 2022, the Company identified errors related to the classification of certain balances and amounts in the line items of the Condensed Consolidated Balance Sheets and Condensed Consolidated Income Statements. These errors resulted in the revision of balances and amounts related to deferred sales inducement assets, liabilities for certain life-contingent annuities, sub-advisor fee expenses, and other operating expense items that impacted previously issued Condensed Consolidated Financial Statements. The impact of these errors to the prior periods' Condensed Consolidated Financial Statements were not considered to be material and had no impact on shareholders' equity or net income (loss). However, to improve the consistency and comparability of the financial statements, management revised the financial statements and related disclosures in this quarterly report. See Note 22 to the Notes to Condensed Consolidated Financial Statements for details of the revisions.

New Accounting Standards

Changes in Accounting Principles – Adopted in Current Year

In March 2020, the Financial Accounting Standards Board (“FASB”) issued ASU 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting.” The new guidance provides optional expedients for applying U.S. GAAP to contracts and other transactions affected by reference rate reform and is effective for contract modifications made between March 12, 2020 and December 31, 2022. If certain criteria are met, an entity will not be required to remeasure or reassess contracts impacted by reference rate reform. The practical expedient allowed by this standard was elected and is being applied prospectively by the Company as reference rate reform unfolds. The contracts modified to date met the criteria for the practical expedient and therefore had no material impact on the Company’s Condensed Consolidated Financial Statements. In December 2022, the FASB issued ASU 2022-06, “Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848” which defers the sunset date of Topic 848 from December 31, 2022 to December 31, 2024, after which entities will no longer be permitted to apply the relief in Topic 848. The amendments are effective for all entities as of December 21, 2022. The Company will continue to evaluate the impacts of reference rate reform on contract modifications and other transactions through December 31, 2024.

In August 2018, the FASB issued ASU 2018-12, “Targeted Improvements to the Accounting for Long Duration Contracts,” ("LDTI"), which included changes to the existing recognition, measurement, presentation and disclosure requirements for long-duration contracts issued by an insurance entity. The Company adopted LDTI effective January 1, 2023, with a transition date of January 1, 2021, using the modified retrospective transition method relating to liabilities for traditional and limited payment contracts and deferred policy acquisition costs associated therewith, and on a retrospective basis, in relation to market risk benefits ("MRBs").

Under the modified retrospective approach, the Company applied the guidance to contracts in force on the transition date on the basis of their existing carrying value, using updated future cash flow assumptions, and eliminated certain related amounts in accumulated other comprehensive income (loss) (“AOCI”). Under the full retrospective transition approach, the Company applied the guidance as of the transition date, using actual historical assumption information as of contract inception, as if the accounting principle had always been applied.

Amounts reported as of March 31, 2023 and December 31, 2022 and for the three months ended March 31, 2023 and 2022 within these Condensed Consolidated Financial Statements are accounted for and presented in accordance with U.S. GAAP reflecting the adoption of LDTI.

LDTI contains four significant changes:

1.Market risk benefits: market risk benefits, a new term for certain contract features that provide for potential benefits in addition to the account balance that expose the Company to other-than-nominal market risk (for example, guaranteed benefits on annuity contracts, including guaranteed minimum withdrawal benefits and guaranteed minimum death benefits on variable annuities), are measured at fair value. Changes in fair value are recorded and presented separately within the income statement, with the exception of changes in fair value due to non-performance risk, which are recognized in other comprehensive income (loss) (“OCI”);

2.Deferred acquisition costs: deferred acquisition costs (“DAC”) are amortized on a constant-level basis, independent of profitability of the underlying business;

3.Liability for future policy benefits: annual review and, if necessary, update of cash flow assumptions used to measure the liability for future policy benefits for nonparticipating traditional and limited-payment insurance contracts is required. These liabilities are discounted using an upper-medium grade fixed income instrument yield which is updated quarterly, with related changes in the liability recognized in OCI; and

4.Enhanced disclosures: enhanced disclosures, including disaggregated roll-forwards of certain balance sheet accounts that provide information about actual and expected cash flows, as well as information about significant inputs, judgments, assumptions and methods used in measurement, are required. The enhanced disclosures are intended to improve the ability of users of the financial statements to evaluate the timing, amount, and uncertainty of cash flows arising from long-duration contracts.

The adoption of LDTI resulted in a decrease in total equity of $3.0 billion as of the transition date of January 1, 2021, comprised of a reduction in AOCI of $0.4 billion and a reduction in retained earnings of $2.6 billion. The primary drivers for this impact to total equity included:

1.the classification of certain benefits as market risk benefits (“MRB”) which were remeasured at fair value as of the transition date. The resulting change in the value of these benefits at the transition date, net of the related deferred tax effect, is recognized in retained earnings, with the exception of the cumulative effect of changes in non-performance risk, net of the related deferred tax effect, which is recognized in AOCI;

2.changes to the discount rate used to measure liabilities for future policyholder benefits which, under LDTI, are remeasured each reporting period using current upper-medium grade fixed-income instrument yields, which are generally considered to be those on single-A rated public corporate debt. The cumulative effect of the remeasurement of these liabilities using the transition date discount rate, net of the related deferred tax effect, is recognized in AOCI; and
