Accounting Policies [Abstract]
Business, Basis of Presentation, and Significant Accounting Policies	1. Business, Basis of Presentation and Significant Accounting Policies Athene Holding Ltd. (AHL), a Bermuda exempted company, together with its subsidiaries (collectively, Athene, we, our, us, or the Company), is a leading financial services company specializing in retirement services that issues, reinsures and acquires retirement savings products in the United States (US) and internationally. We conduct business primarily through the following consolidated subsidiaries: • Our non-US reinsurance subsidiaries, to which AHL’s other insurance subsidiaries and third-party ceding companies directly and indirectly reinsure a portion of their liabilities, including Athene Life Re Ltd. (ALRe), a Bermuda exempted company, and Athene Life Re International Ltd. (ALReI); and • Athene USA Corporation, an Iowa corporation (together with its subsidiaries, AUSA). In addition, we consolidate certain variable interest entities (VIEs) for which we have determined we are the primary beneficiary. See Note 4 – Variable Interest Entities for further information on VIEs. Consolidation and Basis of Presentation —We have prepared the accompanying condensed consolidated financial statements in accordance with accounting principles generally accepted in the United States of America (GAAP) for interim financial information and the United States Securities and Exchange Commission’s rules and regulations for Form 10-Q and Article 10 of Regulation S-X. The accompanying condensed consolidated financial statements are unaudited and reflect all adjustments, consisting only of normal recurring items except as noted below, considered necessary for fair statement of the results for the interim periods presented. All intercompany accounts and transactions have been eliminated. Interim operating results are not necessarily indicative of the results expected for the entire year. For entities that are consolidated, but not wholly owned, we allocate a portion of the income or loss and corresponding equity to the owners other than us. We include the aggregate of the income or loss and corresponding equity that is not owned by us in noncontrolling interests in the consolidated financial statements. The condensed consolidated balance sheet as of December 31, 2020 has been derived from the audited financial statements, but does not include all of the information and footnotes required by GAAP for complete financial statements. Therefore, these condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2020. The preparation of financial statements requires the use of management estimates. Actual results may differ from estimates used in preparing the condensed consolidated financial statements. During the quarter ended September 30, 2021, we recorded an out-of-period adjustment that affected the condensed consolidated statements of income. The adjustment related to the correction of errors in taxable income by jurisdiction, which resulted in the misstatement of income tax expense. The adjustment overstated consolidated net income for the three and nine months ended September 30, 2021 by $116 million and $63 million, respectively. We evaluated the out-of-period adjustment and determined it was not material to the condensed consolidated financial statements for either the three or nine months ended September 30, 2021, or any other previously reported period. Merger —On March 8, 2021, we entered into an Agreement and Plan of Merger (Merger Agreement), by and among the Company, Apollo Global Management, Inc., a Delaware corporation (AGM), Tango Holdings, Inc., a Delaware corporation and a direct wholly owned subsidiary of AGM (HoldCo), Blue Merger Sub, Ltd., a Bermuda exempted company and a direct wholly owned subsidiary of HoldCo (AHL Merger Sub), and Green Merger Sub, Inc., a Delaware corporation and a direct wholly owned subsidiary of HoldCo (AGM Merger Sub). The Company and AGM have agreed, subject to the terms and conditions of the Merger Agreement, to effect an all-stock merger transaction to combine our respective businesses by: (1) AGM merging with AGM Merger Sub, with AGM surviving such merger as a direct wholly owned subsidiary of HoldCo (AGM Merger), (2) the Company merging with AHL Merger Sub, with the Company surviving such merger as a direct wholly owned subsidiary of HoldCo (AHL Merger and, together with the AGM Merger, Mergers), and (3) as of the effective time of the Mergers, changing the name of HoldCo to be Apollo Global Management, Inc. At the effective time of the Mergers, each AHL Class A common share, subject to certain exceptions, will be converted automatically into the right to receive 1.149 shares of HoldCo common stock. The Mergers are expected to close in January 2022, subject to shareholder and regulatory approvals and other customary closing conditions. Adopted Accounting Pronouncements Codification Improvements to Subtopic 310-20, Receivables – Nonrefundable Fees and Other Costs (ASU 2020-08) The amendments in this update clarify that callable debt securities should be reevaluated each reporting period to determine if the amortized cost exceeds the amount repayable by the issuer at the next earliest call date and, if so, the excess should be amortized to the next call date. We adopted this update January 1, 2021 on a prospective basis for existing or newly purchased callable debt securities. The adoption of this update did not have a material effect on our condensed consolidated financial statements. Clarifying the Interactions between Topic 321, Topic 323, and Topic 815 (ASU 2020-01) The amendments in this update are related to certain equity securities without a readily determinable fair value that apply measurement alternative to measure based on cost, minus impairment, if any, adjusted for any observable price changes in orderly transactions of identical or similar investments of the same issuer. The amendment clarifies that an entity should consider observable transactions that require it to either apply or discontinue the equity method of accounting for the purposes of applying the measurement alternative immediately before applying or upon discontinuing the equity method. The amendment further clarifies that for the purpose of applying accounting for certain forward contracts or purchased options, an entity should not consider whether the underlying securities would be accounted for under the equity method or the fair value option upon settlement or exercise. We adopted this update on a prospective basis effective January 1, 2021. This update did not have a material effect on our condensed consolidated financial statements. Income Taxes – Simplifying the Accounting for Income Taxes (ASU 2019-12) The amendments in this update simplify the accounting for income taxes by eliminating certain exceptions to the tax accounting guidance related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period, and the recognition of deferred tax liabilities related to foreign investment ownership changes. It also simplifies aspects of the accounting for franchise taxes and enacted changes in tax laws or rates and clarifies the accounting for transactions that result in a step-up in the tax basis of goodwill and allocating consolidated income taxes to separate financial statements of entities not subject to income tax. We adopted this update January 1, 2021 and applied certain aspects of the update retrospectively while other aspects were applied on a modified retrospective basis. The adoption of this update did not have a material effect on our condensed consolidated financial statements. Recently Issued Accounting Pronouncements Insurance – Targeted Improvements to the Accounting for Long-Duration Contracts (ASU 2020-11, ASU 2019-09, ASU 2018-12) These updates amend four key areas pertaining to the accounting and disclosures for long-duration insurance and investment contracts. • The update requires cash flow assumptions used to measure the liability for future policy benefits to be updated at least annually and no longer allows a provision for adverse deviation. The remeasurement of the liability associated with the update of assumptions is required to be recognized in net income. Loss recognition testing is eliminated for traditional and limited-payment contracts. The update also requires the discount rate used in measuring the liability to be an upper-medium grade fixed-income instrument yield, which is to be updated at each reporting date. The change in liability due to changes in the discount rate is to be recognized in other comprehensive income. • The update simplifies the amortization of deferred acquisition costs and other balances amortized in proportion to premiums, gross profits, or gross margins, requiring such balances to be amortized on a constant level basis over the expected term of the contracts. Deferred costs are required to be written off for unexpected contract terminations but are not subject to impairment testing. • The update requires certain contract features meeting the definition of market risk benefits to be measured at fair value. Among the features included in this definition are guaranteed lifetime withdrawal benefit (GLWB) and guaranteed minimum death benefit (GMDB) riders attached to our annuity products. The change in fair value of the market risk benefits is to be recognized in net income, excluding the portion attributable to changes in instrument-specific credit risk which is recognized in other comprehensive income. • The update also introduces disclosure requirements around the liability for future policy benefits, policyholder account balances, market risk benefits, separate account liabilities, and deferred acquisition costs. This includes disaggregated rollforwards of these balances and information about significant inputs, judgments, assumptions and methods used in their measurement. We are required to adopt these updates on January 1, 2023. Certain provisions of the update are required to be adopted on a fully retrospective basis, while others may be adopted on a modified retrospective basis. Early adoption is permitted. We are currently evaluating the impact of this guidance on our consolidated financial statements.

Key loan characteristics affecting the estimate include, among others: time to maturity, delinquency status, loan-to-value ratios, debt service coverage ratios, etc. Key macroeconomic variables include unemployment rates, London Inter-bank Offered Rate (LIBOR), commercial real estate price index, and market liquidity score. Management reviews and approves forecasted macroeconomic variables, along with the reasonable and supportable forecast period and mean reversion technique. Management also evaluates assumptions from independent third parties and these assumptions have a high degree of subjectivity. The mean reversion technique varies by macroeconomic variable and may vary by geographic location. As of September 30, 2021, our reasonable and supportable forecast period was one year, after which, we revert to the 20-year or greater historical average over one year.

See Note 10 – Related Parties for further information on the related party loans. Credit Quality Indicators Residential mortgage loans – The underwriting process for our residential mortgage loans includes an evaluation of relevant credit information including past loan performance, credit scores, loan-to-value and other relevant information. Subsequent to purchase or origination, we closely monitor economic conditions and loan performance to manage and evaluate our exposure to credit risk in our residential mortgage loan portfolio. The primary credit quality indicator monitored for residential mortgage loans is loan performance. Nonperforming residential mortgage loans are 90 days or more past due and/or are in non-accrual status.

Loan-to-value and debt service coverage ratios are measures we use to assess the risk and quality of commercial mortgage loans other than those under development. Loans under development are not evaluated using these ratios as the properties underlying these loans are generally not yet income-producing and the value of the underlying property significantly fluctuates based on the progress of construction. Therefore, the risk and quality of loans under development are evaluated based on the aging and geographical distribution of such loans as shown above. The loan-to-value ratio is expressed as a percentage of the amount of the loan relative to the value of the underlying property. A loan-to-value ratio in excess of 100% indicates the unpaid loan amount exceeds the value of the underlying collateral. Loan-to-value information is updated annually as part of the re-underwriting process supporting the National Association of Insurance Commissioners (NAIC) risk-based capital rating criteria.

A debt service ratio of less than 1.0 indicates a property’s operations do not generate enough income to cover debt payments. Debt service coverage ratios are updated as more recent financial statements become available, at least annually or as frequently as quarterly in some cases.

Non-Consolidated Securities and Investment Funds Fixed maturity securities – We invest in securitization entities as a debt holder or an investor in the residual interest of the securitization vehicle. These entities are deemed VIEs due to insufficient equity within the structure and lack of control by the equity investors over the activities that significantly impact the economics of the entity. In general, we are a debt investor within these entities and, as such, hold a variable interest; however, due to the debt holders’ lack of ability to control the decisions within the trust that significantly impact the entity, and the fact the debt holders are protected from losses due to the subordination of the equity tranche, the debt holders are not deemed the primary beneficiary. Securitization vehicles in which we hold the residual tranche are not consolidated because we do not unilaterally have substantive rights to remove the general partner, or when assessing related party interests, we are not under common control, as defined by GAAP, with the related party, nor are substantially all of the activities conducted on our behalf; therefore, we are not deemed the primary beneficiary. Debt investments and investments in the residual tranche of securitization entities are considered debt instruments and are held at fair value on the balance sheet and classified as AFS or trading. Investment funds – Investment funds include non-fixed income, alternative investments in the form of limited partnerships or similar legal structures. Equity securities – We invest in preferred equity securities issued by entities deemed to be VIEs due to insufficient equity within the structure. Our risk of loss associated with our non-consolidated investments depends on the investment. Investment funds, equity securities and trading securities are limited to the carrying value plus unfunded commitments. AFS securities are limited to amortized cost plus unfunded commitments.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	3. Derivative Instruments We use a variety of derivative instruments to manage risks, primarily equity, interest rate, credit, foreign currency and market volatility. See Note 5 – Fair Value for information about the fair value hierarchy for derivatives. The following table presents the notional amount and fair value of derivative instruments: September 30, 2021 December 31, 2020 Notional Amount Fair Value Notional Amount Fair Value (In millions) Assets Liabilities Assets Liabilities Derivatives designated as hedges Foreign currency swaps 5,765 $ 202 $ 71 4,417 $ 134 $ 181 Foreign currency forwards 2,584 — 136 2,038 3 9 Foreign currency interest rate swaps 5,571 210 4 — — — Foreign currency forwards on net investments 232 5 — 173 — 2 Total derivatives designated as hedges 417 211 137 192 Derivatives not designated as hedges Equity options 55,746 3,093 45 53,666 3,209 22 Futures 38 62 — 24 58 2 Total return swaps 155 — 2 97 6 — Foreign currency swaps 1,897 34 10 1,510 96 — Interest rate swaps 482 71 1 803 — 34 Credit default swaps 10 — 4 10 — 4 Foreign currency forwards 5,781 109 30 3,595 17 44 Embedded derivatives Funds withheld including related party 1,829 45 2,806 59 Interest sensitive contract liabilities — 14,102 — 12,873 Total derivatives not designated as hedges 5,198 14,239 6,192 13,038 Total derivatives $ 5,615 $ 14,450 $ 6,329 $ 13,230 Derivatives Designated as Hedges Cash Flow Hedges – We use foreign currency swaps to convert foreign currency denominated cash flows of investments or liabilities to US dollars to reduce cash flow fluctuations due to changes in currency exchange rates. These swaps will expire by March 2052. The following is a summary of the gains (losses) related to cash flow hedges: Three months ended September 30, Nine months ended September 30, (In millions) 2021 2020 2021 2020 Foreign currency swaps – Other comprehensive income $ 114 $ (178) $ 171 $ 140 Foreign currency swaps – Investment related gains (losses) (21) — 6 — There were no amounts deemed ineffective during the three and nine months ended September 30, 2021 and 2020 . As of September 30, 2021, no amounts are expected to be reclassified to income within the next 12 months. Fair Value Hedges – We use foreign currency forward contracts and foreign currency interest rate swaps that are designated and accounted for as fair value hedges. We use foreign currency forward contracts to hedge certain exposures to foreign currency risk. The price is agreed upon at the time of the contract and payment is made at a specified future date. We use foreign currency interest rate swaps to hedge certain exposures to foreign currency risk and interest rate risk relating to foreign currency denominated funding agreements. The following represents the carrying amount and the cumulative fair value hedging adjustments included in the hedged assets or liabilities: September 30, 2021 December 31, 2020 (In millions) Carrying amount of the hedged assets or liabilities 1 Cumulative amount of fair value hedging gains (losses) Carrying amount of the hedged assets or liabilities 1 Cumulative amount of fair value hedging gains (losses) AFS securities – Foreign currency forwards $ 3,598 $ (64) $ 1,932 $ 117 Mortgage loans – Foreign currency forwards 1,316 (24) — — Interest sensitive contract liabilities Foreign currency forwards 87 4 65 (1) Foreign currency interest rate swaps 2,574 98 — — 1 The carrying amount disclosed for AFS securities is amortized cost.

(In millions) Derivatives Hedged Items Net Amount Excluded 1 Nine months ended September 30, 2021 Investment related gains (losses) Foreign currency forwards $ 338 $ (337) $ 1 $ (37) Foreign currency interest rate swaps (82) 82 — — Interest sensitive contract benefits Foreign currency interest rate swaps 13 (11) 2 — Nine months ended September 30, 2020 Investment related gains (losses) – Foreign currency forwards $ (60) $ 59 $ (1) $ — 1 Amount of derivative gains (losses) excluded from the assessment of hedge effectiveness are primarily recognized in income through changes in fair value. Foreign currency forward gains and losses excluded from the assessment of hedge effectiveness that were recognized in OCI were gains of $86 million and $0 million for the three months ended September 30, 2021 and 2020, respectively, and gains of $90 million and $0 million for the nine months ended September 30, 2021 and 2020, respectively. Net Investment Hedges – We use foreign currency forwards to hedge the foreign currency exchange rate risk of our investments in subsidiaries that have a reporting currency other than the US dollar. We assess hedge effectiveness based on the changes in forward rates. During the three months ended September 30, 2021 and 2020, these derivatives had gains of $7 million and $3 million, respectively. During the nine months ended September 30, 2021 and 2020 , these derivatives had gains of $5 million and $5 million, respectively. These derivatives are included in foreign currency translation and other adjustments on the condensed consolidated statements of comprehensive income. As of September 30, 2021 and December 31, 2020, the cumulative foreign currency translation recorded in accumulated other comprehensive income (AOCI) related to these net investment hedges were gains of $5 million and $0 million, respectively. During the three and nine months ended September 30, 2021 and 2020 , there were no amounts deemed ineffective. Derivatives Not Designated as Hedges Equity options – We use equity indexed options to economically hedge fixed indexed annuity products that guarantee the return of principal to the policyholder and credit interest based on a percentage of the gain in a specified market index, primarily the S&P 500. To hedge against adverse changes in equity indices, we enter into contracts to buy equity indexed options. The contracts are net settled in cash based on differentials in the indices at the time of exercise and the strike price. Futures – Futures contracts are purchased to hedge the growth in interest credited to the customer as a direct result of increases in the related indices. We enter into exchange-traded futures with regulated futures commission clearing brokers who are members of a trading exchange. Under exchange-traded futures contracts, we agree to purchase a specified number of contracts with other parties and to post variation margin on a daily basis in an amount equal to the difference in the daily fair values of those contracts. Total return swaps – We purchase total rate of return swaps to gain exposure and benefit from a reference asset or index without ownership. Total rate of return swaps are contracts in which one party makes payments based on a set rate, either fixed or variable, while the other party makes payments based on the return of the underlying asset or index, which includes both the income it generates and any capital gains. Interest rate swaps – We use interest rate swaps to reduce market risks from interest rate changes and to alter interest rate exposure arising from duration mismatches between assets and liabilities. With an interest rate swap, we agree with another party to exchange the difference between fixed-rate and floating-rate interest amounts tied to an agreed-upon notional principal amount at specified intervals. Credit default swaps – Credit default swaps provide a measure of protection against the default of an issuer or allow us to gain credit exposure to an issuer or traded index. We use credit default swaps coupled with a bond to synthetically create the characteristics of a reference bond. These transactions have a lower cost and are generally more liquid relative to the cash market. We receive a periodic premium for these transactions as compensation for accepting credit risk. Hedging credit risk involves buying protection for existing credit risk. The exposure resulting from the agreements, which is usually the notional amount, is equal to the maximum proceeds that must be paid by a counterparty for a defaulted security. If a credit event occurs on a reference entity, then a counterparty who sold protection is required to pay the buyer the trade notional amount less any recovery value of the security. Embedded derivatives – We have embedded derivatives which are required to be separated from their host contracts and reported as derivatives. Host contracts include reinsurance agreements structured on a modified coinsurance (modco) or funds withheld basis and indexed annuity products. The following is a summary of the gains (losses) related to derivatives not designated as hedges: Three months ended September 30, Nine months ended September 30, (In millions) 2021 2020 2021 2020 Equity options $ (45) $ 606 $ 1,501 $ (303) Futures (2) 50 53 63 Swaps (40) 29 (4) 9 Foreign currency forwards 75 (114) 25 (70) Embedded derivatives on funds withheld 205 1,077 463 1,260 Amounts recognized in investment related gains (losses) 193 1,648 2,038 959 Embedded derivatives in indexed annuity products 1 132 (553) (716) (910) Total gains (losses) on derivatives not designated as hedges $ 325 $ 1,095 $ 1,322 $ 49 1 Included in interest sensitive contract benefits on the condensed consolidated statements of income. Credit Risk —We may be exposed to credit-related losses in the event of counterparty nonperformance on derivative financial instruments. Generally, the current credit exposure of our derivative contracts is the fair value at the reporting date less any collateral received from the counterparty. We manage credit risk related to over-the-counter derivatives by entering into transactions with creditworthy counterparties. Where possible, we maintain collateral arrangements and use master netting agreements that provide for a single net payment from one counterparty to another at each due date and upon termination. We have also established counterparty exposure limits, where possible, in order to evaluate if there is sufficient collateral to support the net exposure. Collateral arrangements typically require the posting of collateral in connection with its derivative instruments. Collateral agreements often contain posting thresholds, some of which may vary depending on the posting party’s financial strength ratings. Additionally, a decrease in our financial strength rating to a specified level can result in settlement of the derivative position. The estimated fair value of our net derivative and other financial assets and liabilities after the application of master netting agreements and collateral were as follows: Gross amounts not offset on the condensed consolidated balance sheets (In millions) Gross amount recognized 1 Financial instruments 2 Collateral (received)/pledged Net amount Off-balance sheet securities collateral 3 Net amount after securities collateral September 30, 2021 Derivative assets $ 3,786 $ (277) $ (3,531) $ (22) $ — $ (22) Derivative liabilities (303) 277 18 (8) — (8) December 31, 2020 Derivative assets $ 3,523 $ (165) $ (3,196) $ 162 $ (46) $ 116 Derivative liabilities (298) 165 144 11 — 11 1 The gross amounts of recognized derivative assets and derivative liabilities are reported on the condensed consolidated balance sheets. As of September 30, 2021 and December 31, 2020, amounts not subject to master netting or similar agreements were immaterial. 2 Represents amounts offsetting derivative assets and derivative liabilities that are subject to an enforceable master netting agreement or similar agreement that are not netted against the gross derivative assets or gross derivative liabilities for presentation on the condensed consolidated balance sheets. 3 For non-cash collateral received, we do not recognize the collateral on our balance sheet unless the obligor (transferor) has defaulted under the terms of the secured contract and is no longer entitled to redeem the pledged asset. Amounts do not include any excess of collateral pledged or received.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Variable Interest Entities	4. Variable Interest Entities As of September 30, 2021, we consolidate the following primary VIEs: • Hamlet Securitization Trust 2020-CRE1 (Hamlet) • A-A SPN-9 (ASREII - ACRASP), L.P. and A-A SPN-9 (ASREII - ALRESP), L.P. (collectively, A-A SPN-9) • A-A Offshore 2021-1 (Java), L.P. (Java) • NNN AGP Opportunities Fund, L.P. and NNN AGP Opportunities Fund II, L.P. (collectively, NNN AGP Opportunities) • A-A Debt Euro Investment Fund (Lux) SCSP and A-A Euro Investment Fund (Lux) SCSP (collectively, A-A Euro) • AOP Finance Partners, LP (AOP) The following summarizes the investments of these consolidated VIEs: (In millions) September 30, 2021 December 31, 2020 Mortgage loans Hamlet $ 1,795 $ 1,880 A-A Euro 230 — Other 17 — Investment funds AOP 241 — A-A SPN-9 181 — NNN AGP Opportunities 106 — Java 80 — A-A Euro 56 — Hamlet was formed to securitize a portion of our commercial mortgage loan portfolio as CMBS securities held by AHL subsidiaries and third-party cedant portfolios. Securitization of these commercial mortgage loans allows retention of the full economics of these assets while being able to pledge these assets as collateral to the Federal Home Loan Bank (FHLB) under the funding agreement program. As substantially all of the activities and economics of Hamlet are conducted on our behalf, we are the primary beneficiary and consolidate Hamlet and the assets are included in mortgage loans on the condensed consolidated balance sheets. Additionally, as Hamlet is in the form of a trust, the commercial mortgage loan assets are included in the pledged assets and funds in trust table in Note 11 – Commitments and Contingencies . A-A SPN-9 is comprised of limited partnership entities that invest in an underlying investment fund. We are a limited partner in these entities and receive a significant portion of the economic benefits and losses, other than management fees and carried interest, as applicable, paid to the general partner in each entity, which are Apollo affiliates and related parties. We do not have any direct voting rights as a limited partner at the A-A SPN-9 level, but we do have an ability to dissolve the underlying investment that results in dissolution of the entities. Therefore, as we have a unilateral ability to ultimately dissolve the entities and also receive a significant portion of the economics of each of the entities, we are deemed to be the primary beneficiary of the VIEs. Java is an investment fund. We are both the general partner and the only limited partner in this investment fund and receive all of the economic benefits and losses. As the general partner, we hired an Apollo affiliate as the related party investment manager who receives management fees and service fees, as applicable. We hold both the power, as a general partner, and significant economics, as a limited partner, satisfying the primary beneficiary criteria. NNN AGP Opportunities is an investment fund formed to purchase US-based net lease properties. We are both the general partner and a limited partner of the fund. As the general partner, we hired an Apollo affiliate as the related party investment manager who receives management fees and service fees, as applicable. We hold both the power, as a general partner, and significant economics, as a limited partner, satisfying the primary beneficiary criteria. A-A Euro is an investment fund formed to purchase investments in European real estate. We are both the general partner and a limited partner in the entity and receive a significant portion of its economic benefits and losses. As the general partner, we hired an Apollo affiliate as the related party investment manager who receives management fees and service fees, as applicable. As we control this entity and receive a significant portion of its economic benefits and losses, we are deemed to be the primary beneficiary of the VIE. AOP is an investment fund formed to participate in a platform that originates loans. We are a limited partner in this entity and receive a significant portion of its economic benefits and losses, other than management fees and carried interest, as applicable, paid to the general partner, which is an Apollo affiliate and related party. We do not have any direct voting rights as a limited partner, but we do have a unilateral ability to dissolve the entity; therefore, we are deemed to be the primary beneficiary of the VIE. No arrangement exists requiring us to provide additional funding in excess of our committed capital investment, liquidity, or the funding of losses or an increase to our loss exposure in excess of our investment in any of the consolidated VIEs.

Fair Value Disclosures [Abstract]
Fair Value	5. Fair Value Fair value is the price we would receive to sell an asset or pay to transfer a liability (exit price) in an orderly transaction between market participants. We determine fair value based on the following fair value hierarchy: Level 1 – Unadjusted quoted prices for identical assets or liabilities in an active market. Level 2 – Quoted prices for inactive markets or valuation techniques that require observable direct or indirect inputs for substantially the full term of the asset or liability. Level 2 inputs include the following: • Quoted prices for similar assets or liabilities in active markets, • Observable inputs other than quoted market prices, and • Observable inputs derived principally from market data through correlation or other means. Level 3 – Prices or valuation techniques with unobservable inputs significant to the overall fair value estimate. These valuations use critical assumptions not readily available to market participants. Level 3 valuations are based on market standard valuation methodologies, including discounted cash flows, matrix pricing or other similar techniques. Net Asset Value (NAV) – Investment funds are typically measured using NAV as a practical expedient in determining fair value and are not classified in the fair value hierarchy. Our carrying value reflects our pro rata ownership percentage as indicated by NAV in the investment fund financial statements, which we may adjust if we determine NAV is not calculated consistent with investment company fair value principles. The underlying investments of the investment funds may have significant unobservable inputs, which may include but are not limited to, comparable multiples and weighted average cost of capital rates applied in valuation models or a discounted cash flow model. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1) 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 instrument’s fair value measurement. We use a number of valuation sources to determine fair values. Valuation sources can include quoted market prices; third-party commercial pricing services; third-party brokers; industry-standard, vendor modeling software that uses market observable inputs; and other internal modeling techniques based on projected cash flows. We periodically review the assumptions and inputs of third-party commercial pricing services through internal valuation price variance reviews, comparisons to internal pricing models, back testing to recent trades, or monitoring trading volumes.

These are classified as Level 2 assets. The pricing services incorporate a variety of market observable information in their valuation techniques, including benchmark yields, trading activity, credit quality, issuer spreads, bids, offers and other reference data. This category typically includes US and non-US corporate bonds, US agency and government guaranteed securities, CLO, ABS, CMBS and RMBS. We also have fixed maturity securities priced based on indicative broker quotes or by employing market accepted valuation models. For certain fixed maturity securities, the valuation model uses significant unobservable inputs and are included in Level 3 in our fair value hierarchy. Significant unobservable inputs used include: discount rates, issue specific credit adjustments, material non-public financial information, estimation of future earnings and cash flows, default rate assumptions, liquidity assumptions and indicative quotes from market makers. These inputs are usually considered unobservable, as not all market participants have access to this data. We value privately placed fixed maturity securities based on the credit quality and duration of comparable marketable securities, which may be securities of another issuer with similar characteristics. In some instances, we use a matrix-based pricing model. These models consider the current level of risk-free interest rates, corporate spreads, credit quality of the issuer and cash flow characteristics of the security. We also consider additional factors such as net worth of the borrower, value of collateral, capital structure of the borrower, presence of guarantees and our evaluation of the borrower’s ability to compete in its relevant market. Privately placed fixed maturity securities are classified as Level 2 or 3. Equity securities – Fair values of publicly traded equity securities are based on quoted market prices and classified as Level 1. Other equity securities, typically private equities or equity securities not traded on an exchange, we value based on other sources, such as commercial pricing services or brokers, and are classified as Level 2 or 3. Mortgage loans – Mortgage loans for which we have elected the fair value option or those held for sale are carried at fair value. We estimate fair value on a monthly basis using discounted cash flow analysis and rates being offered for similar loans to borrowers with similar credit ratings. Loans with similar characteristics are aggregated for purposes of the calculations. The discounted cash flow model uses unobservable inputs, including estimates of discount rates and loan prepayments. Mortgage loans are classified as Level 3. Investment funds – Certain investment funds for which we elected the fair value option are included in Level 3 and are priced based on market accepted valuation models. The valuation models use significant unobservable inputs, which include material non-public financial information, estimation of future distributable earnings and demographic assumptions. These inputs are usually considered unobservable, as not all market participants have access to this data. Funds withheld at interest embedded derivative – We estimate the fair value of the embedded derivative based on the change in the fair value of the assets supporting the funds withheld payable under modco and funds withheld reinsurance agreements. As a result, the fair value of the embedded derivative is classified as Level 2 or 3 based on the valuation methods used for the assets held supporting the reinsurance agreements. Derivatives – Derivative contracts can be exchange traded or over-the-counter. Exchange-traded derivatives typically fall within Level 1 of the fair value hierarchy depending on trading activity. Over-the-counter derivatives are valued using valuation models or an income approach using third-party broker valuations. Valuation models require a variety of inputs, including contractual terms, market prices, yield curves, credit curves, measures of volatility, prepayment rates and correlation of the inputs. We consider and incorporate counterparty credit risk in the valuation process through counterparty credit rating requirements and monitoring of overall exposure. We also evaluate and include our own nonperformance risk in valuing derivatives. The majority of our derivatives trade in liquid markets; therefore, we can verify model inputs and model selection does not involve significant management judgment. These are typically classified within Level 2 of the fair value hierarchy. Cash and cash equivalents, including restricted cash – The carrying amount for cash equals fair value. We estimate the fair value for cash equivalents based on quoted market prices. These assets are classified as Level 1. Interest sensitive contract liabilities embedded derivative – Embedded derivatives related to interest sensitive contract liabilities with fixed indexed annuity products are classified as Level 3. The valuations include significant unobservable inputs associated with economic assumptions and actuarial assumptions for policyholder behavior. AmerUs Closed Block – We elected the fair value option for the future policy benefits liability in the AmerUs Closed Block. Our valuation technique is to set the fair value of policyholder liabilities equal to the fair value of assets. There is an additional component which captures the fair value of the open block’s obligations to the closed block business. This component is the present value of the projected release of required capital and future earnings before income taxes on required capital supporting the AmerUs Closed Block, discounted at a rate which represents a market participant’s required rate of return, less the initial required capital. Unobservable inputs include estimates for these items. The AmerUs Closed Block policyholder liabilities and any corresponding reinsurance recoverable are classified as Level 3. ILICO Closed Block – We elected the fair value option for the ILICO Closed Block. Our valuation technique is to set the fair value of policyholder liabilities equal to the fair value of assets. There is an additional component which captures the fair value of the open block’s obligations to the closed block business. This component uses the present value of future cash flows which include commissions, administrative expenses, reinsurance premiums and benefits, and an explicit cost of capital. The discount rate includes a margin to reflect the business and nonperformance risk. Unobservable inputs include estimates for these items. The ILICO Closed Block policyholder liabilities and corresponding reinsurance recoverable are classified as Level 3. Universal life liabilities and other life benefits – We elected the fair value option for certain blocks of universal and other life business ceded to Global Atlantic. We use a present value of liability cash flows. Unobservable inputs include estimates of mortality, persistency, expenses, premium payments and a risk margin used in the discount rates that reflects the riskiness of the business. These universal life policyholder liabilities and corresponding reinsurance recoverable are classified as Level 3. Fair Value Option — The following represents the gains (losses) recorded for instruments for which we have elected the fair value option, including related parties: Three months ended September 30, Nine months ended September 30, (In millions) 2021 2020 2021 2020 Trading securities $ (23) $ 24 $ (31) $ (8) Investment funds 4 (57) 439 109 Future policy benefits 21 (4) 70 (31) Total gains (losses) $ 2 $ (37) $ 478 $ 70 Gains and losses on trading securities are recorded in investment related gains (losses) on the condensed consolidated statements of income. For fair valu e option mortgage loans, we record interest income in net investment income and subsequent changes in fair value in investment related gains (losses) on the condensed consolidated statements of income. Gains and losses related to investment funds, including related party investment funds, are recorded in net investment income on the condensed consolidated statements of income. We record the change in fair value of future policy benefits to future policy and other policy benefits on the condensed consolidated statements of income.

Significant unobservable inputs occur when we could not obtain or corroborate the quantitative detail of the inputs. This applies to fixed maturity securities, equity securities, mortgage loans and certain derivatives, as well as embedded derivatives in liabilities. Additional significant unobservable inputs are described below. AFS and trading securities – For certain fixed maturity securities, internal models are used to calculate the fair value. We use a discounted cash flow approach. The discount rate is the significant unobservable input due to the determined credit spread being internally developed, illiquid, or as a result of other adjustments made to the base rate. The base rate represents a market comparable rate for securities with similar characteristics. This excludes assets for which significant unobservable inputs are not developed internally, primarily consisting of broker quotes. Interest sensitive contract liabilities – embedded derivative – Significant unobservable inputs we use in the fixed indexed annuities embedded derivative of the interest sensitive contract liabilities valuation include: 1. Nonperformance risk – For contracts we issue, we use the credit spread, relative to the Treasury curve based on our public credit rating as of the valuation date. This represents our credit risk for use in the estimate of the fair value of embedded derivatives. 2. Option budget – We assume future hedge costs in the derivative’s fair value estimate. The level of option budgets determines the future costs of the options and impacts future policyholder account value growth. 3. Policyholder behavior – We regularly review the lapse and withdrawal assumptions (surrender rate). These are based on our initial pricing assumptions updated for actual experience. Actual experience may be limited for recently issued products. The following summarizes the unobservable inputs for AFS and trading securities and the embedded derivatives of fixed indexed annuities: September 30, 2021 (In millions, except for percentages) Fair value Valuation technique Unobservable inputs Minimum Maximum Weighted average Impact of an increase in the input on fair value AFS and trading securities $ 7,351 Discounted cash flow Discount rate 1.4 % 17.7 % 4.9 % 1 Decrease Interest sensitive contract liabilities – fixed indexed annuities embedded derivatives $ 14,102 Option budget method Nonperformance risk 0.1 % 0.9 % 0.5 % 2 Decrease Option budget 0.4 % 3.3 % 1.8 % 3 Increase Surrender rate 5.1 % 9.7 % 7.1 % 4 Decrease December 31, 2020 (In millions, except for percentages) Fair value Valuation technique Unobservable inputs Minimum Maximum Weighted average Impact of an increase in the input on fair value AFS and trading securities $ 5,858 Discounted cash flow Discount rate 1.7 % 35.0 % 4.6 % 1 Decrease Interest sensitive contract liabilities – fixed indexed annuities embedded derivatives $ 12,873 Option budget method Nonperformance risk 0.0 % 1.1 % 0.5 % 2 Decrease Option budget 0.6 % 3.5 % 1.9 % 3 Increase Surrender rate 5.3 % 9.5 % 7.1 % 4 Decrease 1 The discount rate weighted average is calculated based on the relative fair values of the securities. 2 The nonperformance risk weighted average is based on the projected excess benefits of reserves used in the calculation of the embedded derivative. 3 The option budget weighted average is calculated based on the indexed account values. 4 The surrender rate weighted average is calculated based on projected account values. Financial Instruments Without Readily Determinable Fair Values —We had elected the measurement alternative for certain equity securities that did not have a readily determinable fair value. During the third quarter of 2021, these equity securities no longer qualified for the measurement alternative and, effective September 30, 2021, are measured at fair value. As of December 31, 2020, the carrying amount of the equity securities was $202 million, with a cumulative recorded impairment of $231 million. Fair Value of Financial Instru

Earnings Per Share The following represents our basic and diluted earnings per share (EPS) calculations, which are calculated using unrounded amounts: Class A Three months ended Nine months ended (In millions, except per share data) September 30, 2021 September 30, 2020 September 30, 2021 Net income available to Athene Holding Ltd. common shareholders – basic and diluted $ 698 $ 622 $ 2,658 Basic weighted average shares outstanding 191.7 193.1 191.5 Dilutive effect of stock compensation plans and warrants 7.1 4.0 6.5 Diluted weighted average shares outstanding 198.8 197.1 198.0 Earnings per share Basic $ 3.64 $ 3.22 $ 13.88 Diluted $ 3.51 $ 3.16 $ 13.42 Nine months ended September 30, 2020 (In millions, except per share data) Class A Class B Class M-1 Class M-2 Class M-3 Class M-4 Net income (loss) available to Athene Holding Ltd. common shareholders – basic and diluted $ 508 $ (98) $ (13) $ (3) $ (4) $ (9) Basic weighted average shares outstanding 182.8 25.4 3.3 0.8 1.0 2.4 Dilutive effect of stock compensation plans and warrants 3.1 — — — — — Diluted weighted average shares outstanding 185.9 25.4 3.3 0.8 1.0 2.4 Earnings per share Basic $ 2.78 $ (3.87) $ (3.87) $ (3.87) $ (3.87) $ (3.87) Diluted $ 2.73 $ (3.87) $ (3.87) $ (3.87) $ (3.87) $ (3.87) For the periods in which we had multiple classes of stock participating in earnings, we used the two-class method for allocating net income available to Athene Holding Ltd. common shareholders to each class of our common stock. During the first quarter of 2020, as a result of the closing of the share transaction discussed further in Note 10 – Related Parties , we converted outstanding Class B shares to Class A shares and Class M shares were converted to Class A shares and warrants. As a result, the EPS calculation for the nine months ended September 30, 2020 allocated all net income for the second and third quarters of 2020 to Class A shares and, for the first quarter of 2020, used only the weighted average shares for the first quarter to allocate first quarter net loss to Class B and Class M shares; however, for Class B and Class M shares, the weighted average shares outstanding represented only that period of time that the shares were outstanding. The warrants issued as part of the conversion of the Class M shares are included within the dilutive effect of stock compensation plans and warrants above if dilutive. Dilutive shares are calculated using the treasury stock method. For Class A shares, this method takes into account shares that can be settled into Class A shares, net of a conversion price. The diluted EPS calculations for Class A shares excluded 1.0 million and 2.8 million shares, restricted stock units, options and warrants as of September 30, 2021 and 2020, respectively, for the three and nine months then ended.

Related Party Transactions [Abstract]
Related Parties	10. Related Parties Apollo Fee structure – Substantially all of our investments are managed by Apollo. Apollo provides us a full suite of services that includes: direct investment management; asset sourcing and allocation; mergers and acquisition sourcing, execution and asset diligence; and strategic support and advice. Apollo also provides certain operational support services for our investment portfolio including investment compliance, tax, legal and risk management support. Apollo has extensive experience managing our investment portfolio and its knowledge of our liability profile enables it to tailor an asset management strategy to fit our specific needs. This strategy has proven responsive to changing market conditions and focuses on earning incremental yield by taking liquidity risk and complexity risk, rather than assuming solely credit risk. Our partnership has enabled us to take advantage of investment opportunities that would likely not otherwise have been available to us. Under the Seventh Amended and Restated Fee Agreement between us and AGM’s subsidiary, Apollo Insurance Solutions Group LP (ISG) (Fee Agreement), we pay Apollo: (1) a base management fee equal to the sum of (i) 0.225% per year of the lesser of (A) the aggregate market value of substantially all of the assets in substantially all of the investment accounts of or relating to us (collectively, the Accounts) on December 31, 2018 of $103.4 billion (Backbook Value) and (B) the aggregate market value of substantially all of the assets in the Accounts at the end of the respective month, plus (ii) 0.15% per year of the amount, if any (Incremental Value), by which the aggregate market value of substantially all of the assets in the Accounts at the end of the respective month exceeds the Backbook Value; plus (2) with respect to each asset in an Account, subject to certain exceptions, that is managed by Apollo and that belongs to a specified asset class tier (Core, Core Plus, Yield, and High Alpha), a sub-allocation fee as follows, which will, in the case of assets acquired after January 1, 2019, be subject to a cap of 10% of the applicable asset’s gross book yield: (i) 0.065% of the market value of Core assets, which include public investment grade corporate bonds, municipal securities, agency RMBS or CMBS, and obligations of governmental agencies or government sponsored entities that are not expressly backed by the US government; (ii) 0.13% of the market value of Core Plus assets, which include private investment grade corporate bonds, fixed rate first lien commercial mortgage loans (CML), and certain obligations issued or assumed by financial institutions and determined by Apollo to be “Tier 2 Capital” under Basel III, a set of recommendations for international banking regulations developed by the Bank for International Settlements; (iii) 0.375% of the market value of Yield assets, which include non-agency RMBS, investment grade CLO, CMBS and other ABS (other than RMBS and CLO), emerging market investments, below investment grade corporate bonds, subordinated debt obligations, hybrid securities or surplus notes issued or assumed by a financial institution, rated preferred equity, residential mortgage loans (RML), bank loans, investment grade infrastructure debt, and floating rate CMLs on slightly transitional or stabilized traditional real estate; (iv) 0.70% of the market value of High Alpha assets, which include subordinated CML, below investment grade CLO, unrated preferred equity, debt obligations originated by MidCap, CMLs for redevelopment or construction loans or secured by non-traditional real estate, below investment grade infrastructure debt, certain loans originated directly by Apollo (other than MidCap loans), and agency mortgage derivatives; and (v) 0.00% of the market value of cash and cash equivalents, US treasuries, non-preferred equities and alternatives. The following represents assets based on the above sub-allocation structure: (In millions, except percentages) September 30, 2021 Percent of Total December 31, 2020 Percent of Total Core $ 50,562 25.2 % $ 49,392 27.3 % Core Plus 45,593 22.7 % 41,516 23.0 % Yield 77,947 38.9 % 64,693 35.8 % High Alpha 7,474 3.7 % 6,200 3.4 % Other 19,118 9.5 % 19,088 10.5 % Total sub-allocation assets $ 200,694 100.0 % $ 180,889 100.0 % Additionally, the Fee Agreement provides for a possible payment by Apollo to us, or a possible payment by us to Apollo, equal to 0.025% of the Incremental Value as of the end of each year, beginning on December 31, 2019, depending upon the percentage of our investments that consist of Core and Core Plus assets. If more than 60% of our invested assets that are subject to the sub-allocation fees are invested in Core and Core Plus assets, we will receive a 0.025% fee reduction on the Incremental Value. If less than 50% of our invested assets that are subject to the sub-allocation fee are invested in Core and Core Plus assets, we will pay an additional fee of 0.025% on Incremental Value. During the three months ended September 30, 2021 and 2020, we incurred management fees, inclusive of the base and sub-allocation fees, of $146 million and $111 million, respectively. During the nine months ended September 30, 2021 and 2020, we incurred management fees, inclusive of the base and sub-allocation fees, of $430 million and $362 million, respectively. Management fees are included within net investment income on the condensed consolidated statements of income. As of September 30, 2021 and December 31, 2020, management fees payable were $53 million and $41 million, respectively, and are included in other liabilities on the condensed consolidated balance sheets. Such amounts include fees incurred attributable to ACRA including all of the noncontrolling interest in ACRA. In addition to the assets on our condensed consolidated balance sheets managed by Apollo, Apollo manages the assets underlying our funds withheld receivable. For these assets, the third-party cedants pay Apollo fees based upon the same fee construct we have with Apollo. Such fees directly reduce the settlement payments that we receive from the third-party cedant and, as such, we indirectly pay those fees. Finally, Apollo charges management fees and carried interest on Apollo-managed funds and other entities in which we invest. Neither the fees paid by such third-party cedants nor the fees or carried interest paid by such Apollo-managed funds or other entities are included in the investment management fee amounts noted above. Investment management agreement (IMA) termination – Our bye-laws currently provide that we may not, and will cause our subsidiaries not to, terminate any IMA among us or any of our subsidiaries, on the one hand, and a member of the Apollo Group (as defined in our bye-laws), on the other hand, other than on June 4, 2023 or any two year anniversary of such date (each such date, an IMA Termination Election Date) and any termination on an IMA Termination Election Date requires (i) the approval of two-thirds of our Independent Directors (as defined in the bye-laws) and (ii) prior written notice to the applicable Apollo subsidiary of such termination at least 30 days, but not more than 90 days, prior to an IMA Termination Election Date. If our Independent Directors make such election to terminate and notice of such termination is delivered, the termination will be effective no earlier than the second anniversary of the applicable IMA Termination Election Date (IMA Termination Effective Date). Notwithstanding the foregoing, (A) except as set forth in clause (B) below, our board of directors may only elect to terminate an IMA on an IMA Termination Election Date if two-thirds of our Independent Directors determine, in their sole discretion and acting in good faith, that either (i) there has been unsatisfactory long-term performance materially detrimental to us by the applicable Apollo subsidiary or (ii) the fees being charged by the applicable Apollo subsidiary are unfair and excessive compared to a comparable asset manager (provided, that in either case such Independent Directors must deliver notice of any such determination to the applicable Apollo subsidiary and the applicable Apollo subsidiary will have until the applicable IMA Termination Effective Date to address such concerns, and provided, further, that in the case of such a determination that the fees being charged by the applicable Apollo subsidiary are unfair and excessive, the applicable Apollo subsidiary has the right to lower its fees to match the fees of such comparable asset manager) and (B) upon the determination by two-thirds of our Independent Directors, we or our subsidiaries may also terminate an IMA with the applicable Apollo subsidiary, on a date other than an IMA Termination Effective Date, as a result of either (i) a material violation of law relating to the applicable Apollo subsidiary’s advisory business, or (ii) the applicable Apollo subsidiary’s gross negligence, willful misconduct or reckless disregard of its obligations under the relevant agreement, in each case of this clause (B), that is materially detrimental to us, and in either case of this clause (B), subject to the delivery of written notice at least 30 days prior to such termination; provided, that in connection with an event described in clause (B)(i) or (B)(ii), the applicable Apollo subsidiary shall have the right to dispute such determination of the Independent Directors within 30 days after receiving notice from us of such determination, in which case the matter will be submitted to binding arbitration and such IMA shall continue to remain in effect during the period of the arbitration (the events described in the foregoing clauses (A) and (B) are referred to in more detail in our bye-laws as “AHL Cause”). Governance – We have a management investment committee, which includes members of our senior management and reports to the risk committee of our board of directors. The committee focuses on strategic decisions involving our investment portfolio, such as approving investment limits, new asset classes and our allocation strategy, reviewing large asset transactions, as well as monitoring our credit risk, and the management of our assets and liabilities. A significant voting interest in the Company is held by shareholders who are members of the Apollo Group. Also, James Belardi, our Chief Executive Officer, is an employee of ISG and receives remuneration from acting as Chief Executive Officer of ISG. Mr. Belardi also owns a 5% profit interest in ISG and in connection with such interest receives distributions in respect of ISG and sub-allocation fees earned by Apollo. Additionally, six of the sixteen members of our board of directors are employees of or consultants to Apollo (including Mr. Belardi). In order to protect against potential conflicts of interest resulting from transactions into which we have entered and will continue to enter into with the Apollo Group, our bye-laws require us to maintain a conflicts committee comprised solely of directors who are not officers or employees of any member of the Apollo Group. The conflicts committee reviews and approves material transactions between us and the Apollo Group, subject to certain exceptions. Other related party transactions A-A Mortgage – We have an equity method investment of $77 million and $444 million as of September 30, 2021 and December 31, 2020, respectively, in A-A Mortgage, which previously held an investment in AmeriHome. On February 16, 2021, Apollo, Athene and AmeriHome announced the sale of AmeriHome to a subsidiary of Western Alliance Bancorporation. This transaction closed on April 7, 2021 and we recognized $182 million of revenue from the premium of the platform sale, net of carry and transaction expenses. Of the total, $174 million was recognized during the first quarter of 2021 as a result of the underlying investment being held at fair value. We have a loan purchase agreement with AmeriHome, which survived the sale. The agreement allows us to purchase residential mortgage loans which AmeriHome has purchased from correspondent sellers and pooled for sale in the secondary market. AmeriHome retains the servicing rights to the sold loans. We purchased no residential mortgage loans under this agreement during the three months ended September 30, 2021 or 2020. We purchased $0 million and $169 million of residential mortgage loans under this agreement during the nine months ended September 30, 2021 and 2020, respectively. Additionally, as of December 31, 2020, we held $360 million of investments issued by AmeriHome or AmeriHome affiliates as related party AFS securities on the condensed consolidated balances sheets. MidCap – We have multiple investments in MidCap including profit participating notes, senior unsecured notes and redeemable preferred stock, which are included in related party AFS or trading securities on the condensed consolidated balance sheets. We also had advanced amounts to MidCap under a subordinated debt facility, which was included in related party other investments on the condensed consolidated balance sheets. During the second quarter 2021, the principal balance of the MidCap subordinated debt facility of $330 million was repaid and we received $19 million as a result of the early repayment. The following summarizes our investments in MidCap: (In millions) September 30, 2021 December 31, 2020 Profit participating notes $ 618 $ 534 Senior unsecured notes 157 — Redeemable preferred stock 8 77 Subordinated debt facility — 328 Total investment in MidCap $ 783 $ 939 Additionally, we hold ABS and CLO securities issued by MidCap affiliates of $801 million and $630 million as of September 30, 2021 and December 31, 2020, respectively, which are included in related party AFS securities on the condensed consolidated balance sheets. Athora – We have a cooperation agreement with Athora, pursuant to which, among other things, (1) for a period of 30 days from the receipt of notice of a cession, we have the right of first refusal to reinsure (i) up to 50% of the liabilities ceded from Athora’s reinsurance subsidiaries to Athora Life Re Ltd. and (ii) up to 20% of the liabilities ceded from a third party to any of Athora’s insurance subsidiaries, subject to a limitation in the aggregate of 20% of Athora’s liabilities, (2) Athora agreed to cause its insurance subsidiaries to consider the purchase of certain funding agreements and/or other spread instruments issued by our insurance subsidiaries, subject to a limitation that the fair market value of such funding agreements purchased by any of Athora’s insurance subsidiaries may generally not exceed 3% of the fair market value of such subsidiary’s total assets, (3) we provide Athora with a right of first refusal to pursue acquisition and reinsurance transactions in Europe (other than the United Kingdom (UK)) and (4) Athora provides us and our subsidiaries with a right of first refusal to pursue acquisition and reinsurance transactions in North America and the UK. Notwithstanding the foregoing, pursuant to the cooperation agreement, Athora is only required to use its reasonable best efforts to cause its subsidiaries to adhere to the provisions set forth in the cooperation agreement and therefore Athora’s ability to cause its subsidiaries to act pursuant to the cooperation agreement may be limited by, among other things, legal prohibitions or the inability to obtain the approval of the board of directors or other applicable governing body of the applicable subsidiary, which approval is solely at the discretion of such governing body. As of September 30, 2021 , we have not exercised our right of first refusal to reinsure liabilities ceded to Athora’s insurance or reinsurance subsidiaries. Our investment in Athora, which is included in related party investment funds on the condensed consolidated balance sheets, was $728 million and $709 million as of September 30, 2021 and December 31, 2020, respectively. Additionally, as of September 30, 2021 and December 31, 2020, we had $116 million and $122 million, respectively, of funding agreements outstanding to Athora . We also have commitments to make additional equity investments in Athora of $695 million as of September 30, 2021. Venerable – We have coinsurance and modco agreements with Venerable Insurance and Annuity Company (VIAC). VIAC is a related party due to our minority equity investment in its holding company’s parent, VA Capital , which was $235 million and $123 million as of September 30, 2021 and December 31, 2020, respectively. The minority equity investment in VA Capital is included in related party investment funds on the condensed consolidated balance sheets and accounted for as an equity method investment. VA Capital is owned by a consortium of investors, led by affiliates of AGM, Crestview Partners III Management, LLC (Crestview) and Reverence Capital Partners L.P. (Reverence), and is the parent of Venerable, which is the parent of VIAC. On June 1, 2021, Apollo Hybrid Value Fund, L.P., AA Direct, L.P. and certain entities affiliated with Athora, collectively through an acquisition vehicle, AP Violet, L.P. (AP Violet), along with Crestview and Reverence agreed to acquire a portion of the minority equity investment in VA Capital from us and Apollo. In the second and third quarters of 2021, we sold portions of our equity investment for $124 million, of which $25 million was deferred consideration, to Crestview, Reverence and AP Violet. We also have term loans receivable from Venerable due in 2033, which are included in related party other investments on the condensed consolidated balance sheets. The loans are held at the principal balance less allowances and were $178 million and $145 million as of September 30, 2021 and December 31, 2020, respectively. While management views the overall transactions with Venerable as favorable to us, the stated interest rate of 6.257% on the initial term loan to Venerable represented a below-market interest rate, and management considered such rate as part of its evaluation and pricing of the reinsurance transactions. Strategic Partnership – We have an agreement pursuant to which we may invest up to $2.5 billion over three years in funds managed by Apollo entities (Strategic Partnership). This arrangement is intended to permit us to invest across the Apollo alternatives platform into credit-oriented, strategic and other alternative investments in a manner and size that is consistent with our existing investment strategy. Fees for such investments payable by us to Apollo would be more favorable to us than market rates, and consistent with our existing alternative investments, investments made under the Strategic Partnership require approval of ISG and remain subject to our existing governance processes, including approval by our conflicts committee where applicable. As of September 30, 2021 and December 31, 2020, we had $274 million and $214 million, respectively, of investments under the Strategic Partnership and these investments are typically included in related party investment funds on the condensed consolidated balance sheets. PK AirFinance – We have an investment in PK AirFinance (PK), an aviation lending business with a portfolio of loans (Aviation Loans). The Aviation Loans are generally fully secured by aircraft leases and aircraft. Apollo owns the PK loan origination platform, including personnel and systems and, pursuant to certain agreements entered into between us, Apollo, and certain entities managed by Apollo, the Aviation Loans are securitized by an SPV for which Apollo acts as ABS manager (ABS-SPV). The ABS-SPV issues tranches of senior notes and subordinated notes, which are secured by the Aviation Loans. As of September 30, 2021 and December 31, 2020, our investment in securitizations of loans originated by PK was $1,364 million and $1,373 million, respectively, and are included in related party AFS or trading securities on the condensed consolidated balance sheets. We also have commitments to make additional investment in securitizations of loans originated by PK of $1,232 million as of September 30, 2021. Apollo/Athene Dedicated Investment Program (ADIP) – Our subsidiary, Athene Co-Invest Reinsurance Affiliate 1A Ltd. (together with its subsidiaries, ACRA) is partially owned by ADIP, which is managed by AGM. ALRe currently holds 36.55% of the economic interests in ACRA, with ADIP holding the remaining 63.45%. During the three months ended September 30, 2021 and 2020, we received capital contributions of $328 million and $0 million, respectively, from ADIP and paid dividends of $0 million and $0 million, respectively, to ADIP. During the nine months ended September 30, 2021 and 2020, we received capital contributions of $648 million and $240 million, respectively, from ADIP and paid dividends of $0 million and $46 million, respectively, to ADIP. Apollo Share Exchange and Related Transactions – On February 28, 2020, we closed a strategic transaction with AGM and certain affiliates of AGM which collectively comprise the Apollo Operating Group (AOG), pursuant to which we sold 27,959,184 newly issued Class A common shares to the AOG for an investment in Apollo of 29,154,519 newly issued AOG units valued at $1.1 billion and we sold 7,575,758 newly issued Class A common shares to the AOG for $350 million. Additionally, Apollo Management Holdings, L.P. (AMH) has the right to purchase up to that number of Class A common shares that would increase by 5 percentage points the percentage of the issued and outstanding Class A common shares beneficially owned by the AOG and certain affiliates, employees and consultants of AGM (inclusive of Class A common shares over which any such persons have a valid proxy), calculated on a fully diluted basis. In connection with the closing of the transaction, we made certain amendments to our bye-laws which, among other things, eliminated our multi-class common share structure. Concurrent with our entry into the transaction agreements, AMH, James Belardi, our Chief Executive Officer, and William Wheeler, our President (each an Other Shareholder), entered into a voting agreement, pursuant to which each Other Shareholder irrevocably appointed AMH as its proxy and attorney-in-fact (Proxy) to vote all of such Other Shareholder’s Class A common shares at any meeting of our shareholders occurring following the closing date and in connection with any written consent of our shareholders following the closing date. The Proxy will be of no force and effect if Apollo and certain affiliates thereof cease to hold some minimum level of ownership not to exceed 7.5% of our Class A common shares.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	11. Commitments and Contingencies Contingent Commitments —We had commitments to make investments, primarily capital contributions to investment funds, inclusive of related party commitments discussed previously, of $13,564 million a nd $7,472 million as of September 30, 2021 and December 31, 2020, respectively. We expect most of our current commitments will be invested over the next five years; however, these commitments could become due any time upon counterparty request. Funding Agreements —We are a member of the FHLB and, through membership, we have issued funding agreements to the FHLB in exchange for cash advances. As of September 30, 2021 and December 31, 2020, we had $2,001 million and $2,002 million, respectively, of FHLB funding agreements outstanding. We are required to provide collateral in excess of the funding agreement amounts outstanding, considering any discounts to the securities posted and prepayment penalties. We have a funding agreement backed notes (FABN) program, which allows Athene Global Funding, a special-purpose, unaffiliated statutory trust, to offer its senior secured medium-term notes. Athene Global Funding uses the net proceeds from each sale to purchase one or more funding agreements from us. As of September 30, 2021 and December 31, 2020, we had $18,292 million and $8,822 million, respectively, of FABN f unding agreements outstanding . We had $6,648 million of board-authorized FABN capacity remaining as of September 30, 2021. During the third quarter of 2020, we established a secured funding agreement backed repurchase agreement (FABR) program, in which a special-purpose, unaffiliated entity entered into repurchase agreements with a bank and the proceeds of the repurchase agreements were used by the special-purpose entity to purchase funding agreements from us. As of September 30, 2021 and December 31, 2020, we had $1,000 million of FABR funding agreements outstanding. Pledged Assets and Funds in Trust (Restricted Assets)— The total restricted assets included on the condensed consolidated balance sheets are as follows: (In millions) September 30, 2021 December 31, 2020 AFS securities $ 9,081 $ 9,884 Trading securities 75 60 Equity securities 27 26 Mortgage loans 4,831 5,028 Investment funds 168 68 Derivative assets 92 107 Short-term investments — 52 Other investments 100 105 Restricted cash 757 738 Total restricted assets $ 15,131 $ 16,068 The restricted assets are primarily related to reinsurance trusts established in accordance with coinsurance agreements and the FHLB and FABR funding agreements described above. Letters of Credit— We have undrawn letters of credit totaling $1,394 million as of September 30, 2021. These letters of credit were issued for our reinsurance program and expire between December 10, 2021 and June 19, 2023. Litigation, Claims and Assessments Corporate-owned Life Insurance (COLI) Matter – In 2000 and 2001, two insurance companies, which were subsequently merged into Athene Annuity and Life Company (AAIA), purchased broad based variable COLI policies from American General Life Insurance Company (American General) that, as of September 30, 2021, had an asset value of $423 million, and is included in other assets on the condensed consolidated balance sheets. In January 2012, the COLI policy administrator delivered to AAIA a supplement to the existing COLI policies and advised that American General and ZC Resource Investment Trust (ZC Trust) had unilaterally implemented changes set forth in the supplement that, if effective, would: (1) potentially negatively impact the crediting rate for the policies and (2) change the exit and surrender protocols set forth in the policies. In March 2013, AAIA filed suit against American General, ZC Trust, and ZC Resource LLC in Chancery Court in Delaware, seeking, among other relief, a declaration that the changes set forth in the supplement were ineffectual and in breach of the parties’ agreement. The parties filed cross motions for judgment as a matter of law, and the court granted defendants’ motion and dismissed without prejudice on ripeness grounds. The issue that negatively impacts the crediting rate for one of the COLI policies has subsequently been triggered and, on April 3, 2018, we filed suit against the same defendants in Chancery Court in Delaware seeking substantially similar relief. Defendants moved to dismiss and the court heard oral arguments on February 13, 2019. The court issued an opinion on July 31, 2019 that did not address the merits, but found that the Chancery Court did not have jurisdiction over our claims and directed us to either amend our complaint or transfer the matter to Delaware Superior Court. The matter has been transferred to the Delaware Superior Court. Defendants renewed their motion to dismiss and the Superior Court heard oral arguments on December 18, 2019. The Superior Court issued an opinion on May 18, 2020 in which it granted in part and denied in part defendants’ motion. The Superior Court denied defendants’ motion with respect to the issue that negatively impacts the crediting rate for one of the COLI policies, which issue will proceed to discovery. The Superior Court granted defendants’ motion and dismissed without prejudice on ripeness grounds claims related to the exit and surrender protocols set forth in the policies, and dismissed defendant ZC Resource LLC. If the supplement is ultimately deemed to be effective, the purported changes to the policies could impair AAIA’s ability to access the value of guarantees associated with the policies. The Superior Court issued a scheduling order providing for a July 2022 trial and the parties are currently engaged in discovery. The value of the guarantees included within the asset value reflected above is $199 million as of September 30, 2021 . Regulatory Matters – From 2015 to 2018, our US insurance subsidiaries experienced increased complaints related to the conversion and administration of the block of life insurance business acquired in connection with our acquisition of Aviva USA and reinsured to affiliates of Global Atlantic. The life insurance policies included in this block have been and are currently being administered by AllianceOne Inc. (AllianceOne), a subsidiary of DXC Technology Company, which was retained by such Global Atlantic affiliates to provide third party administration services on such policies. AllianceOne also administers a small block of annuity policies that were on Aviva USA’s legacy policy administration systems that were also converted in connection with the acquisition of Aviva USA and have experienced some similar service and administration issues, but to a lesser degree. As a result of the difficulties experienced with respect to the administration of such policies, we have received notifications from several state regulators, including but not limited to New York State Department of Financial Services (NYSDFS), the California Department of Insurance (CDI) and the Texas Department of Insurance (TDI), indicating, in each case, that the respective regulator planned to undertake a market conduct examination or enforcement proceeding of the applicable US insurance subsidiary relating to the treatment of policyholders subject to our reinsurance agreements with affiliates of Global Atlantic and the conversion of the life and annuity policies, including the administration of such blocks by AllianceOne. We entered into consent orders with several state regulators, including the NYSDFS, the CDI and the TDI, to resolve underlying matters in the respective states. All fines and costs, including those associated with remediation plans, paid in connection with the consent orders are subject to indemnification by Global Atlantic or affiliates of Global Atlantic. Pursuant to the terms of the reinsurance agreements between us and the relevant affiliates of Global Atlantic, the applicable affiliates of Global Atlantic have financial responsibility for the ceded life block and are subject to significant administrative service requirements, including compliance with applicable law. The agreements also provide for indemnification to us, including for administration issues.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation—We have prepared the accompanying condensed consolidated financial statements in accordance with accounting principles generally accepted in the United States of America (GAAP) for interim financial information and the United States Securities and Exchange Commission’s rules and regulations for Form 10-Q and Article 10 of Regulation S-X. The accompanying condensed consolidated financial statements are unaudited and reflect all adjustments, consisting only of normal recurring items except as noted below, considered necessary for fair statement of the results for the interim periods presented. All intercompany accounts and transactions have been eliminated. Interim operating results are not necessarily indicative of the results expected for the entire year.For entities that are consolidated, but not wholly owned, we allocate a portion of the income or loss and corresponding equity to the owners other than us. We include the aggregate of the income or loss and corresponding equity that is not owned by us in noncontrolling interests in the consolidated financial statements.The condensed consolidated balance sheet as of December 31, 2020 has been derived from the audited financial statements, but does not include all of the information and footnotes required by GAAP for complete financial statements. Therefore, these condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2020.
Consolidation	The accompanying condensed consolidated financial statements are unaudited and reflect all adjustments, consisting only of normal recurring items except as noted below, considered necessary for fair statement of the results for the interim periods presented. All intercompany accounts and transactions have been eliminated. Interim operating results are not necessarily indicative of the results expected for the entire year.For entities that are consolidated, but not wholly owned, we allocate a portion of the income or loss and corresponding equity to the owners other than us. We include the aggregate of the income or loss and corresponding equity that is not owned by us in noncontrolling interests in the consolidated financial statements.The condensed consolidated balance sheet as of December 31, 2020 has been derived from the audited financial statements, but does not include all of the information and footnotes required by GAAP for complete financial statements.
Use of Estimates	The preparation of financial statements requires the use of management estimates. Actual results may differ from estimates used in preparing the condensed consolidated financial statements.
Adopted Accounting Pronouncements and Recently Issued Accounting Pronouncements	Adopted Accounting Pronouncements Codification Improvements to Subtopic 310-20, Receivables – Nonrefundable Fees and Other Costs (ASU 2020-08) The amendments in this update clarify that callable debt securities should be reevaluated each reporting period to determine if the amortized cost exceeds the amount repayable by the issuer at the next earliest call date and, if so, the excess should be amortized to the next call date. We adopted this update January 1, 2021 on a prospective basis for existing or newly purchased callable debt securities. The adoption of this update did not have a material effect on our condensed consolidated financial statements. Clarifying the Interactions between Topic 321, Topic 323, and Topic 815 (ASU 2020-01) The amendments in this update are related to certain equity securities without a readily determinable fair value that apply measurement alternative to measure based on cost, minus impairment, if any, adjusted for any observable price changes in orderly transactions of identical or similar investments of the same issuer. The amendment clarifies that an entity should consider observable transactions that require it to either apply or discontinue the equity method of accounting for the purposes of applying the measurement alternative immediately before applying or upon discontinuing the equity method. The amendment further clarifies that for the purpose of applying accounting for certain forward contracts or purchased options, an entity should not consider whether the underlying securities would be accounted for under the equity method or the fair value option upon settlement or exercise. We adopted this update on a prospective basis effective January 1, 2021. This update did not have a material effect on our condensed consolidated financial statements. Income Taxes – Simplifying the Accounting for Income Taxes (ASU 2019-12) The amendments in this update simplify the accounting for income taxes by eliminating certain exceptions to the tax accounting guidance related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period, and the recognition of deferred tax liabilities related to foreign investment ownership changes. It also simplifies aspects of the accounting for franchise taxes and enacted changes in tax laws or rates and clarifies the accounting for transactions that result in a step-up in the tax basis of goodwill and allocating consolidated income taxes to separate financial statements of entities not subject to income tax. We adopted this update January 1, 2021 and applied certain aspects of the update retrospectively while other aspects were applied on a modified retrospective basis. The adoption of this update did not have a material effect on our condensed consolidated financial statements. Recently Issued Accounting Pronouncements Insurance – Targeted Improvements to the Accounting for Long-Duration Contracts (ASU 2020-11, ASU 2019-09, ASU 2018-12) These updates amend four key areas pertaining to the accounting and disclosures for long-duration insurance and investment contracts. • The update requires cash flow assumptions used to measure the liability for future policy benefits to be updated at least annually and no longer allows a provision for adverse deviation. The remeasurement of the liability associated with the update of assumptions is required to be recognized in net income. Loss recognition testing is eliminated for traditional and limited-payment contracts. The update also requires the discount rate used in measuring the liability to be an upper-medium grade fixed-income instrument yield, which is to be updated at each reporting date. The change in liability due to changes in the discount rate is to be recognized in other comprehensive income. • The update simplifies the amortization of deferred acquisition costs and other balances amortized in proportion to premiums, gross profits, or gross margins, requiring such balances to be amortized on a constant level basis over the expected term of the contracts. Deferred costs are required to be written off for unexpected contract terminations but are not subject to impairment testing. • The update requires certain contract features meeting the definition of market risk benefits to be measured at fair value. Among the features included in this definition are guaranteed lifetime withdrawal benefit (GLWB) and guaranteed minimum death benefit (GMDB) riders attached to our annuity products. The change in fair value of the market risk benefits is to be recognized in net income, excluding the portion attributable to changes in instrument-specific credit risk which is recognized in other comprehensive income. • The update also introduces disclosure requirements around the liability for future policy benefits, policyholder account balances, market risk benefits, separate account liabilities, and deferred acquisition costs. This includes disaggregated rollforwards of these balances and information about significant inputs, judgments, assumptions and methods used in their measurement. We are required to adopt these updates on January 1, 2023. Certain provisions of the update are required to be adopted on a fully retrospective basis, while others may be adopted on a modified retrospective basis. Early adoption is permitted. We are currently evaluating the impact of this guidance on our consolidated financial statements.
