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 retirement services company that issues, reinsures and acquires retirement savings products in all United States (U.S.) states and the District of Columbia, and the United Kingdom (UK). We conduct business primarily through the following consolidated subsidiaries: • Our non-U.S. 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, Athene USA). In addition, we consolidate certain variable interest entities (VIEs), for which we determined we are the primary beneficiary. 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, considered necessary for fair statement of the results for the interim periods presented. All significant intercompany accounts and transactions have been eliminated. Interim operating results are not necessarily indicative of the results expected for the entire year, particularly in light of the material risks and uncertainties surrounding the spread of the Coronavirus Disease of 2019 (COVID-19), which has resulted in significant volatility in the financial markets. The condensed consolidated balance sheet as of December 31, 2019 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, 2019 . The preparation of financial statements requires the use of management estimates. Our estimates may vary as more information about the extent to which COVID-19 and the resulting impact on economic conditions and the financial markets become known. Actual results may differ from estimates used in preparing the condensed consolidated financial statements. VIE Deconsolidation – During the first quarter 2020, as a result of the Apollo Global Management, Inc. (AGM and, together with its subsidiaries, Apollo) share transaction discussed further in Note 9 – Related Parties , we reassessed the consolidation conclusions for the following VIEs which are managed by Apollo affiliates: • AAA Investments (Co-Invest VI), L.P. (CoInvest VI); • AAA Investments (Co-Invest VII), L.P. (CoInvest VII); • AAA Investments (Other), L.P. (CoInvest Other); • Entities included under our agreement to purchase funds managed by Apollo entities (Strategic Partnership). Following the share transaction we determined that we are no longer the primary beneficiary of these entities, as a result of Apollo receiving significant economics of these entities through their increased economic ownership in the Company. We did not recognize a gain or loss upon deconsolidation, as the deconsolidated VIEs accounted for their assets and liabilities at fair value. As of March 31, 2020 , the deconsolidated VIEs are included at net asset value (NAV) in related party investment funds on the condensed consolidated balance sheets. Summary of Significant Accounting Policies The following accounting policies have been updated for the adoption of Accounting Standards Update (ASU) 2016-13 and related ASUs, and apply for reporting periods beginning January 1, 2020. Investments Purchased Credit Deteriorated (PCD) Investments – We purchase certain structured securities, primarily residential mortgage backed securities (RMBS), and re-performing mortgage loans having experienced a more-than-insignificant deterioration in credit quality since their origination which upon our assessment have been determined to meet the definition of PCD investments. Additionally, structured securities classified as beneficial interests follow the initial measurement guidance for PCD investments if there is a significant difference between contractual cash flows adjusted for expected prepayments and expected cash flows at the date of recognition. The initial allowance for credit losses for PCD investments is recorded through a gross-up adjustment to the initial amortized cost. For mortgage loans, the initial allowance is determined using the methodology described in the Credit Losses – Assets Held at Amortized Cost and Off-Balance Sheet Credit Exposures section. For structured securities classified as beneficial interests, the initial allowance is calculated as the present value of the difference between contractual cash flows adjusted for expected prepayments and expected cash flows at the date of recognition. The non-credit purchase discount or premium is amortized into investment income using the effective interest method. The credit discount, represented by the allowance for expected credit losses, is remeasured each period following the policies for measuring credit losses described in the Credit Losses – Assets Held at Amortized Cost and Off-Balance Sheet Credit Exposures and Credit Losses – Available-for-Sale Securities sections below. Credit Losses – Assets Held at Amortized Cost and Off-Balance Sheet Credit Exposures – We establish an allowance for expected credit losses at the time of purchase for assets held at amortized cost, which primarily includes our residential and commercial mortgage loan portfolios, but also includes certain other loans and reinsurance assets. The allowance for expected credit losses represents the portion of the asset's amortized cost basis that we do not expect to collect due to credit losses over the asset's contractual life, considering past events, current conditions, and reasonable and supportable forecasts of future economic conditions or macroeconomic forecasts. We use a quantitative probability of default and loss given default methodology to develop our estimate of expected credit loss. We develop the estimate on a collective basis factoring in the risk characteristics of the assets in the portfolio. If an asset does not share similar risk characteristics with other assets, the asset is individually assessed. Allowance estimates are highly dependent on expectations of future economic conditions and macroeconomic forecasts, which involve significant judgment and subjectivity. We use quantitative modeling to develop the allowance for expected credit losses. Key inputs into the model include data pertaining to the characteristics of the assets, historical losses and current market conditions. Additionally, the model incorporates management’s expectations around future economic conditions and macroeconomic forecasts over a reasonable and supportable forecast period, after which the model reverts to historical averages. These inputs, the reasonable and supportable forecast period, and reversion to historical average technique are subject to a formal governance and review process by management. Additionally, management considers qualitative adjustments to the model output to the extent that any relevant information regarding the collectability of the asset is available and not already considered in the quantitative model. If we determine that a financial asset has become collateral dependent, which we determine to be when foreclosure is probable, the allowance is measured as the difference between amortized cost and the fair value of the collateral, less any expected costs to sell. The initial allowance for invested assets held at amortized cost other than for PCD investments, and subsequent changes in the allowance including PCD investments, are recorded through a charge to credit loss expense within investment related gains (losses) on the condensed consolidated statements of income (loss). Credit loss expense for reinsurance assets held at amortized cost is recorded through policy and other operating expenses on the condensed consolidated statements of income (loss). We limit accrued interest income on loans to 90 days of interest. Once a loan becomes 90 days past due, the loan is put on non-accrual status and any accrued interest is written off. Once a loan is on non-accrual status, we first apply any payments received to the principal of the loan, and once the principal is repaid, we include amounts received in net investment income. We have elected to present accrued interest receivable separately in accrued investment income on the condensed consolidated balance sheets. We have also elected the practical expedient to exclude the accrued interest receivable from the amortized cost balance used to calculate the allowance given our policy to write off such balances in a timely manner. Any write-off of accrued interest is recorded through a reversal of net investment income on the condensed consolidated statements of income (loss). Upon determining that all or a portion of the amortized cost of an asset is uncollectible, which is generally when all efforts for collection are exhausted, the amortized cost is written off against the existing allowance. Any write off in excess of the existing allowance is recorded through credit loss expense within investment related gains (losses) on the condensed consolidated statements of income (loss). We also have certain off-balance sheet credit exposures for which we establish a liability for expected future credit losses. These exposures primarily relate to commitments to fund commercial or residential mortgage loans that are not unconditionally cancelable. The methodology for estimating the liability for these credit exposures is consistent with that described above, with the additional consideration pertaining to the probability of funding. At the time the commitment expires or is funded, the liability is reversed and an allowance for expected credit losses is established, as applicable. The liability for off-balance sheet credit exposures is included in other liabilities on the condensed consolidated balance sheets. The establishment of the initial liability and all subsequent changes are recorded through credit loss expense within investment related gains (losses) on the condensed consolidated statements of income (loss). Credit Losses – Available-for-Sale Securities – We evaluate available-for-sale (AFS) securities with a fair value that has declined below amortized cost to determine how the decline in fair value should be recognized. If we determine, based on the facts and circumstances related to the specific security, that we intend to sell a security or it is more likely than not that we would be required to sell a security before the recovery of its amortized cost, any existing allowance for credit losses is reversed and the amortized cost of the security is written down to fair value. If neither of these conditions exist, we evaluate whether the decline in fair value has resulted from a credit loss or other factors. For non-structured AFS securities, we qualitatively consider relevant facts and circumstances in evaluating whether a decline below fair value is credit-related. Relevant facts and circumstances include but are not limited to: (1) the extent to which the fair value is less than amortized cost; (2) changes in agency credit ratings, (3) adverse conditions related to the security’s industry or geographical area, (4) failure to make scheduled payments, and (5) other known changes in the financial condition of the issuer or quality of any underlying collateral or credit enhancements. For structured AFS securities meeting the definition of beneficial interests, the qualitative assessment is bypassed, and any securities having experienced a decline in fair value below amortized cost move directly to a quantitative analysis. If upon completion of this analysis it is determined that a potential credit loss exists, an allowance for expected credit losses is established equal to the amount by which the present value of expected cash flows is less than amortized cost, limited by the amount by which fair value is less than amortized cost. A non-structured security’s cash flow estimates are derived from scenario-based outcomes of expected corporate restructurings or the disposition of assets using security-specific facts and circumstances including timing, security interests and loss severity. A structured security’s cash flow estimates are based on security-specific facts and circumstances that may include collateral characteristics, expectations of delinquency and default rates, loss severity, prepayments and structural support, including subordination and guarantees. The expected cash flows are discounted at the effective interest rate implicit to the security at the date of purchase or the current yield to accrete a structured security. For securities with a contractual interest rate that varies based on changes in an independent factor, such as an index or rate, the effective interest rate is calculated based on the factor as it changes over the life of the security. Inherently under the discounted cash flow model, both the timing and amount of cash flows affect the measurement of the allowance for expected credit losses. The allowance for expected credit losses is remeasured each period for the passage of time, any change in expected cash flows, and changes in the fair value of the security. All impairments, whether intent or requirement to sell or credit-related, are recorded through a charge to credit loss expense within investment related gains (losses) on the condensed consolidated statements of income (loss). All changes in the allowance for expected credit losses are recorded through credit loss expense within investment related gains (losses) on the condensed consolidated statements of income (loss). We have elected to present accrued interest receivable separately in accrued investment income on the condensed consolidated balance sheets. We have also elected the practical expedient to exclude the accrued interest receivable from the amortized cost balance used to calculate the allowance for expected credit losses, as we have a policy to write off such balances in a timely manner, when they become 90 days past due. Any write-off of accrued interest is recorded through a reversal of net investment income on the condensed consolidated statements of income (loss). Upon determining that all or a portion of the amortized cost of an asset is uncollectible, which is generally when all efforts for collection are exhausted, the amortized cost is written off against the existing allowance. Any write off in excess of the existing allowance is recorded through credit loss expense within investment related gains (losses) on the condensed consolidated statements of income (loss). Adopted Accounting Pronouncements Financial Instruments – Credit Losses (ASU 2019-05, ASU 2019-04, ASU 2018-19 and ASU 2016-13) This update limits the number of credit impairment models used for different assets and results in accelerated credit loss recognition on assets held at amortized cost, which primarily includes our commercial and residential mortgage loans, but also includes certain other loans and reinsurance assets. The identification of PCD financial assets includes all assets that have experienced a more-than-insignificant deterioration in credit since origination. Additionally, changes in the expected cash flows of purchased credit-deteriorated financial assets are recognized immediately in the income statement. AFS securities are not in scope of the new credit loss model, but were subject to targeted improvements including the establishment of a valuation allowance for credit losses versus the previous direct write down approach. We adopted this update effective January 1, 2020 with a cumulative-effect adjustment that decreased retained earnings by $117 million net of tax and offsetting impacts to DAC, DSI, VOBA and the SOP 03-1 reserve. The adjustment to retained earnings primarily relates to the establishment of an allowance on our commercial mortgage loan portfolio, which represented approximately 1.59% of the amortized cost of the portfolio, but also includes immaterial impacts relating to other assets in scope, including residential mortgage loans, funds withheld at interest, and reinsurance recoverable. Additionally, the update requires investments previously considered purchased credit impaired (PCI), which includes certain of our residential mortgage loans and RMBS to become subject to a modified PCD framework at the transition date. Any required allowance at transition for these assets is to be recorded through a gross-up of the amortized cost, rather than a charge to retained earnings. Additionally, under the AFS impairment model, the recording of an allowance is prohibited in instances where fair value exceeds amortized cost as such securities are not considered impaired under the AFS impairment model. Therefore, no allowance was recorded at transition for PCI RMBS that were in an unrealized gain position. The transition increase of amortized cost and corresponding valuation allowance for residential mortgage loans and RMBS was $36 million and $17 million , respectively. Collaborative Arrangements (ASU 2018-18) The amendments in this update provide guidance on whether certain transactions between collaborative arrangement participants should be accounted for as revenue under Topic 606, providing comparability in the presentation of revenue for certain transactions. We adopted this update effective January 1, 2020. This update did not have a material effect on our consolidated financial statements. Consolidation (ASU 2018-17) The amendments in this update expand certain discussions in the VIE guidance, including considerations necessary for determining when a decision-making fee is a variable interest. We adopted this update effective January 1, 2020. The adoption of this update did not have a material effect on our consolidated financial statements. Cloud Computing Arrangements (ASU 2018-15) The amendments in this update align the requirements for capitalizing implementation costs incurred in a cloud computing service arrangement with the requirements for capitalizing implementation costs incurred for internal-use software. We adopted this update on a prospective basis effective January 1, 2020. This update did not have a material effect on our consolidated financial statements. Fair Value Measurement – Disclosure Requirements (ASU 2018-13) The amendments in this update modify the disclosure requirements for fair value measurements by removing, modifying or adding certain disclosures. On October 1, 2018, we early adopted the removal and modification of certain disclosures as permitted. The additional disclosures in the update were adopted effective January 1, 2020. The adoption of this update did not have a material effect on our consolidated financial statements. Intangibles – Simplifying the Test for Goodwill Impairment (ASU 2017-04) The amendments in this update simplify the subsequent measurement of goodwill by eliminating the comparison of the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill to determine the goodwill impairment loss. With the adoption of this guidance, a goodwill impairment is the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of the goodwill allocated to that reporting unit. Entities continue to have the option to perform a qualitative assessment to determine if a quantitative impairment test is necessary. We do not have material goodwill and adopted this update on a prospective basis effective January 1, 2020. The adoption of this update did not have a material effect on our consolidated financial statements. Recently Issued Accounting Pronouncements Insurance – Targeted Improvements to the Accounting for Long-Duration Contracts (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 the guaranteed lifetime withdrawal benefits (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. The amendments in ASU 2018-12 were originally intended to become effective January 1, 2021; however, with the issuance of ASU 2019-09, we will not be required to adopt the amendments until January 1, 2022. 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. 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 will be required to adopt this update January 1, 2021 and apply certain aspects of the update retrospectively while other aspects will be applied on a modified retrospective basis. Early adoption is permitted. We are currently evaluating the impact of this guidance on our consolidated financial statements.

Of this total, eight were in an unrealized loss position 12 months or more. The unrealized losses on AFS securities can primarily be attributed to changes in market interest rates since acquisition. We did not recognize the unrealized losses in income as we intend to hold these securities and it is not more likely than not we will be required to sell a security before the recovery of its amortized cost.

Loan Valuation Allowance — The allowances for our mortgage loan portfolio and other loans is summarized as follows: Three months ended March 31, 2020 (In millions) Commercial Mortgage Residential Mortgage Related Party Other Investments Total Beginning balance $ 10 $ 1 $ — $ 11 Adoption of accounting standard 167 43 11 221 Provision for expected credit losses 166 37 1 204 Ending balance $ 343 $ 81 $ 12 $ 436 Residential mortgage loans – Our allowance model for residential mortgage loans is based on the characteristics of the loans in our portfolio, historical economic data and loss information, and current and forecasted economic conditions. Key loan characteristics affecting the estimate include, among others: time to maturity, delinquency status, original credit scores and loan-to-value ratios. Key macroeconomic variables include unemployment rates and the housing price index. 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 March 31, 2020 , our reasonable and supportable forecast period ranged from 3 months – 1 year , after which, we revert to the 30-year or greater historical average over a period of up to 9 months and then continue at those averages through the contractual life of the loan. Commercial mortgage loans – Our allowance model for commercial mortgage loans is based on the characteristics of the loans in our portfolio, historical economic data and loss information, and current and forecasted economic conditions. 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, rent growth, capitalization rates, and the housing price index.

Related party other investments – The allowance model for the loans included in related party other investments derives an estimate based on historical loss data available for similarly rated unsecured corporate debt obligations, while also incorporating management’s expectations around prepayment. 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. The following represents our residential loan portfolio by origination year and performance status: March 31, 2020 (In millions) 2020 2019 2018 2017 2016 Prior Total Current (less than 30 days past due) $ 38 $ 998 $ 2,042 $ 547 $ 151 $ 9 $ 3,785 30 to 59 days past due — 47 36 32 15 1 131 60 to 89 days past due — 7 11 8 4 — 30 Over 90 days past due — 9 17 32 15 2 75 Total residential mortgages $ 38 $ 1,061 $ 2,106 $ 619 $ 185 $ 12 $ 4,021 As of December 31, 2019 , $67 million of our residential mortgage loans were nonperforming.

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 NAIC risk based capital rating criteria. The following represents the loan-to-value ratio of the commercial mortgage loan portfolio, excluding those under development, by origination year: March 31, 2020 (In millions) 2020 2019 2018 2017 2016 Prior Total Less than 50% $ 149 $ 760 $ 207 $ 147 $ 74 $ 1,351 $ 2,688 50% to 60% 143 1,128 786 332 40 172 2,601 61% to 70% 441 2,023 1,481 476 46 108 4,575 71% to 80% 342 599 287 95 — 54 1,377 81% to 100% — — — — — 40 40 Commercial mortgage loans $ 1,075 $ 4,510 $ 2,761 $ 1,050 $ 160 $ 1,725 $ 11,281 The following represents the loan-to-value ratio of the commercial mortgage loan portfolio, excluding those under development, net of valuation allowances: (In millions) December 31, 2019 Less than 50% $ 2,640 50% to 60% 2,486 61% to 70% 4,093 71% to 80% 1,162 81% to 100% 31 Commercial mortgage loans $ 10,412 The debt service coverage ratio is expressed as a percentage of a property’s net operating income to its debt service payments. 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. The following represents the debt service coverage ratio of the commercial mortgage loan portfolio, excluding those under development, by origination year: March 31, 2020 (In millions) 2020 2019 2018 2017 2016 Prior Total Greater than 1.20x $ 860 $ 3,661 $ 2,703 $ 974 $ 160 $ 1,599 $ 9,957 1.00x – 1.20x 149 849 58 53 — 114 1,223 Less than 1.00x 66 — — 23 — 12 101 Commercial mortgage loans $ 1,075 $ 4,510 $ 2,761 $ 1,050 $ 160 $ 1,725 $ 11,281 The following represents the debt service coverage ratio of the commercial mortgage loan portfolio, excluding those under development, net of valuation allowances: (In millions) December 31, 2019 Greater than 1.20x $ 9,212 1.00x – 1.20x 1,166 Less than 1.00x 34 Commercial mortgage loans $ 10,412 Investment Funds —Our investment fund portfolio consists of funds that employ various strategies and include investments in real estate, real assets, credit , equity and natural resources.

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.

The following table presents the notional amount and fair value of derivative instruments: March 31, 2020 December 31, 2019 Notional Amount Fair Value Notional Amount Fair Value (In millions) Assets Liabilities Assets Liabilities Derivatives designated as hedges Foreign currency swaps 3,226 $ 519 $ 58 3,158 $ 113 $ 56 Foreign currency forwards 801 6 2 717 1 9 Foreign currency forwards on net investments 136 4 — 139 — 2 Total derivatives designated as hedges 529 60 114 67 Derivatives not designated as hedges Equity options 48,654 999 11 49,549 2,746 5 Futures 7 19 7 8 10 1 Total return swaps 124 — 25 106 6 — Foreign currency swaps 11 2 — 35 2 1 Interest rate swaps 776 9 88 776 3 4 Credit default swaps 10 — 7 10 — 3 Foreign currency forwards 3,230 52 24 1,924 7 16 Embedded derivatives Funds withheld including related party (389 ) 24 1,395 31 Interest sensitive contract liabilities — 9,089 — 10,942 Total derivatives not designated as hedges 692 9,275 4,169 11,003 Total derivatives $ 1,221 $ 9,335 $ 4,283 $ 11,070 Derivatives Designated as Hedges Foreign currency swaps – We use foreign currency swaps to convert foreign currency denominated cash flows of an investment to U.S. dollars to reduce cash flow fluctuations due to changes in currency exchange rates. Certain of these swaps are designated and accounted for as cash flow hedges, which will expire by December 2050 . During the three months ended March 31, 2020 and 2019 , we had foreign currency swap gains of $401 million and losses of $8 million , respectively, recorded in AOCI. There were no amounts reclassified to income and no amounts deemed ineffective for the three months ended March 31, 2020 and 2019 . As of March 31, 2020 , no amounts are expected to be reclassified to income within the next 12 months. Foreign currency forwards – 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. Certain of these forwards are designated and accounted for as fair value hedges. As of March 31, 2020 and December 31, 2019 , the carrying amount of the hedged AFS securities was $659 million and $456 million , respectively, and the cumulative amount of fair value hedging adjustments included in the hedged AFS securities included losses of $8 million and gains of $1 million , respectively. The gains and losses on derivatives and the related hedged items in fair value hedge relationships are recorded in investment related gains (losses) on the condensed consolidated statements of income (loss). During the three months ended March 31, 2020 and 2019 , the derivatives had gains of $12 million and $3 million , respectively, and t he related hedged items had losses of $8 million and $3 million , respectively. Foreign currency forwards on net investments – We have foreign currency forwards designated as net investment hedges. These forwards hedge the foreign currency exchange rate risk of our investments in subsidiaries that have a reporting currency other than the U.S. dollar. We assess hedge effectiveness based on the changes in forward rates. During the three months ended March 31, 2020 , these derivatives had gains of $13 million , which are included in foreign currency translation and other adjustments on the condensed consolidated statements of comprehensive income (loss). As of March 31, 2020 and December 31, 2019 , the cumulative foreign currency translation recorded in AOCI related to these net investment hedges were gains of $11 million and losses of $2 million , respectively. During the three months ended March 31, 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 March 31, (In millions) 2020 2019 Equity options $ (1,581 ) $ 849 Futures 16 (11 ) Swaps (75 ) 18 Foreign currency forwards 67 6 Embedded derivatives on funds withheld (1,446 ) 830 Amounts recognized in investment related gains (losses) (3,019 ) 1,692 Embedded derivatives in indexed annuity products 1 1,177 (1,017 ) Total gains (losses) on derivatives not designated as hedges $ (1,842 ) $ 675 1 Included in interest sensitive contract benefits on the condensed consolidated statements of income (loss). 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 March 31, 2020 Derivative assets $ 1,610 $ (64 ) $ (1,589 ) $ (43 ) $ (170 ) $ (213 ) Derivative liabilities (222 ) 64 15 (143 ) — (143 ) December 31, 2019 Derivative assets $ 2,888 $ (67 ) $ (2,743 ) $ 78 $ (145 ) $ (67 ) Derivative liabilities (97 ) 67 31 1 — 1 1 T he gross amounts of recognized derivative assets and derivative liabilities are reported on the c ondensed c onsolidated balance sheets. As of March 31, 2020 and December 31, 2019, 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.

Fair Value Disclosures [Abstract]
Fair Value	4. 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. 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. 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. The following represents the hierarchy for our assets and liabilities measured at fair value on a recurring basis: March 31, 2020 (In millions) Total NAV Level 1 Level 2 Level 3 Assets AFS securities U.S. government and agencies $ 40 $ — $ 40 $ — $ — U.S. state, municipal and political subdivisions 909 — — 872 37 Foreign governments 291 — — 291 — Corporate 44,468 — — 43,235 1,233 CLO 6,641 — — 6,519 122 ABS 4,563 — — 3,646 917 CMBS 2,291 — — 2,246 45 RMBS 6,468 — — 6,426 42 Total AFS securities 65,671 — 40 63,235 2,396 Trading securities U.S. government and agencies 11 — 8 3 — U.S. state, municipal and political subdivisions 112 — — 112 — Corporate 1,425 — — 1,393 32 CLO 3 — — — 3 ABS 94 — — 80 14 CMBS 51 — — 51 — RMBS 283 — — 213 70 Total trading securities 1,979 — 8 1,852 119 Equity securities 206 — 23 176 7 Mortgage loans 26 — — — 26 Investment funds 157 136 — — 21 Funds withheld at interest – embedded derivative (374 ) — — — (374 ) Derivative assets 1,610 — 19 1,591 — Short-term investments 393 — 42 284 67 Other investments 98 — — 98 — Cash and cash equivalents 5,419 — 5,419 — — Restricted cash 564 — 564 — — Investments in related parties AFS securities Corporate 19 — — 19 — CLO 1,040 — — 1,040 — ABS 2,487 — — 600 1,887 Total AFS securities – related party 3,546 — — 1,659 1,887 Trading securities CLO 42 — — 10 32 ABS 676 — — — 676 Total trading securities – related party 718 — — 10 708 Equity securities 49 — — — 49 Investment funds 1,097 118 — — 979 Funds withheld at interest – embedded derivative (15 ) — — — (15 ) Reinsurance recoverable 2,115 — — — 2,115 Total assets measured at fair value $ 83,259 $ 254 $ 6,115 $ 68,905 $ 7,985 (Continued) March 31, 2020 (In millions) Total NAV Level 1 Level 2 Level 3 Liabilities Interest sensitive contract liabilities Embedded derivative $ 9,089 $ — $ — $ — $ 9,089 Universal life benefits 1,322 — — — 1,322 Future policy benefits AmerUs Life Insurance Company (AmerUs) Closed Block 1,481 — — — 1,481 Indianapolis Life Insurance Company (ILICO) Closed Block and life benefits 778 — — — 778 Derivative liabilities 222 — 7 208 7 Funds withheld liability – embedded derivative 24 — — 24 — Total liabilities measured at fair value $ 12,916 $ — $ 7 $ 232 $ 12,677 (Concluded) December 31, 2019 (In millions) Total NAV Level 1 Level 2 Level 3 Assets AFS securities U.S. government and agencies $ 36 $ — $ 36 $ — $ — U.S. state, municipal and political subdivisions 1,541 — — 1,501 40 Foreign governments 327 — — 327 — Corporate 47,228 — — 46,503 725 CLO 7,349 — — 7,228 121 ABS 5,118 — — 3,744 1,374 CMBS 2,400 — — 2,354 46 RMBS 7,375 — — 7,375 — Total AFS securities 71,374 — 36 69,032 2,306 Trading securities U.S. government and agencies 11 — 8 3 — U.S. state, municipal and political subdivisions 135 — — 135 — Corporate 1,456 — — 1,456 — CLO 6 — — — 6 ABS 108 — — 92 16 CMBS 51 — — 51 — RMBS 303 — — 251 52 Total trading securities 2,070 — 8 1,988 74 Equity securities 247 — 43 201 3 Mortgage loans 27 — — — 27 Investment funds 154 132 — — 22 Funds withheld at interest – embedded derivative 801 — — — 801 Derivative assets 2,888 — 10 2,878 — Short-term investments 406 — 46 319 41 Other investments 93 — — 93 — Cash and cash equivalents 4,240 — 4,240 — — Restricted cash 402 — 402 — — (Continued) December 31, 2019 (In millions) Total NAV Level 1 Level 2 Level 3 Investments in related parties AFS securities Corporate 19 — — 19 — CLO 936 — — 936 — ABS 2,849 — — 525 2,324 Total AFS securities – related party 3,804 — — 1,480 2,324 Trading securities CLO 74 — — 36 38 ABS 711 — — — 711 Total trading securities – related party 785 — — 36 749 Equity securities 64 — — — 64 Investment funds 819 687 — — 132 Funds withheld at interest – embedded derivative 594 — — — 594 Short-term investments — — — — — Reinsurance recoverable 1,821 — — — 1,821 Total assets measured at fair value $ 90,589 $ 819 $ 4,785 $ 76,027 $ 8,958 Liabilities Interest sensitive contract liabilities Embedded derivative $ 10,942 $ — $ — $ — $ 10,942 Universal life benefits 1,050 — — — 1,050 Future policy benefits AmerUs Closed Block 1,546 — — — 1,546 ILICO Closed Block and life benefits 755 — — — 755 Derivative liabilities 97 — 1 93 3 Funds withheld liability – embedded derivative 31 — — 31 — Total liabilities measured at fair value $ 14,421 $ — $ 1 $ 124 $ 14,296 (Concluded) Fair Value Valuation Methods —We used the following valuation methods and assumptions to estimate fair value: AFS and trading securities – We obtain the fair value for most marketable securities without an active market from several commercial pricing services. 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 U.S. and non-U.S. corporate bonds, U.S. 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: 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 March 31, (In millions) 2020 2019 Trading securities $ (223 ) $ 56 Investment funds (300 ) (4 ) Future policy benefits 65 (40 ) Total gains (losses) $ (458 ) $ 12 Gains and losses on trading securities are recorded in investment related gains (losses) on the condensed consolidated statements of income (loss). 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 (loss). 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 (loss). 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 (loss).

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 U.S. Department of the Treasury (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: March 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 $ 3,522 Discounted cash flow Discount 3.8 % 19.0 % 7.8 % 1 Decrease Interest sensitive contract liabilities – fixed indexed annuities embedded derivatives $ 9,089 Option budget method Nonperformance risk 1.9 % 2.5 % 2.3 % 2 Decrease Option budget 0.7 % 3.7 % 1.9 % 3 Increase Surrender rate 5.0 % 10.4 % 7.2 % 4 Decrease December 31, 2019 Fair value Valuation technique Unobservable inputs Minimum Maximum Weighted average Impact of an increase in the input on fair value AFS and trading securities $ 1,289 Discounted cash flow Discount 3.0 % 9.0 % 6.6 % 1 Decrease Interest sensitive contract liabilities – fixed indexed annuities embedded derivatives $ 10,942 Option budget method Nonperformance risk 0.2 % 1.1 % 0.6 % 2 Decrease Option budget 0.7 % 3.7 % 1.9 % 3 Increase Surrender rate 3.5 % 8.1 % 7.1 % 4 Decrease 1 The discount 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.

The financial instruments presented above are reported at carrying value on the condensed consolidated balance sheets; however, in the case of policy loans, funds withheld at interest and liability, short-term investments, short-term debt, and securities to repurchase, the carrying amount approximates fair value. Investment in related parties – Other investments – The fair value of related party other investments is determined using a discounted cash flow model using discount rates for similar investments. Interest sensitive contract liabilities – The carrying and fair value of interest sensitive contract liabilities above includes fixed indexed and traditional fixed annuities without mortality or morbidity risks, funding agreements and payout annuities without life contingencies. The embedded derivatives within fixed indexed annuities without mortality or morbidity risks are excluded, as they are carried at fair value. The valuation of these investment contracts is based on discounted cash flow methodologies using significant unobservable inputs. The estimated fair value is determined using current market risk-free interest rates, adding a spread to reflect our nonperformance risk and subtracting a risk margin to reflect uncertainty inherent in the projected cash flows. Long-term debt – We obtain the fair value of long-term debt from commercial pricing services. These are classified as Level 2. 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.

Debt	6. Debt Short-term Borrowing —As of March 31, 2020 , we had $400 million of short-term debt outstanding with the Federal Home Loan Bank (FHLB) through their variable rate short-term federal funds program. As of March 31, 2020 , the borrowings had maturity dates ranging from May 4, 2020 to May 11, 2020 and a weighted average interest rate of 1.80% , with interest due at maturity. In connection with short-term borrowings, the FHLB requires the borrower to purchase member stock and post sufficient collateral to secure the borrowing. See Note 10 – Commitments and Contingencies for further discussion regarding existing collateral posting with the FHLB. Senior Notes —In the second quarter of 2020, AHL issued $500 million of senior unsecured notes due April 3, 2030. The senior notes have a 6.150% coupon rate, payable semi-annually. The senior notes are callable, in whole or in part, at any time prior to January 3, 2030 by AHL, at a price equal to the greater of (1) 100% of the principal and any accrued and unpaid interest and (2) an amount equal to the sum of the present values of remaining scheduled payments, discounted from the scheduled payment date to the redemption date at the Treasury Rate (as defined in the second supplemental indenture, dated April 3, 2020) plus 50 basis points, and any accrued and unpaid interest.

As a result, the EPS calculation for the first quarter of 2020 uses the weighted average shares for the quarter for all classes to allocate net income; however, for Class B and Class M shares, the weighted average shares outstanding represents only that period of time that the shares were outstanding. The warrants issued as part of the conversion of the Class M shares are evaluated for dilution within the dilutive effect of stock compensation plans. We use the two-class method for allocating net income available to Athene Holding Ltd. common shareholders to each class of our common stock. 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 11.1 million and 34.8 million shares, restricted stock units, options and warrants as of March 31, 2020 and 2019 , respectively.

Preferred stock ranks senior to our common stock with respect to dividends, to the extent declared, and in liquidation, to the extent of the liquidation preference. Common Stock— During the first quarter of 2020, shareholders approved amendments to our bye-laws which eliminated our multi-class share structure at closing of the share transaction with Apollo. See Note 9 – Related Parties for further information on this transaction. On February 28, 2020, all Class B shares were converted to Class A shares on a one-to-one basis. Class M shares were converted to Class A shares representing 5% of the Class M value and warrants representing 95% of the Class M value. The warrants were issued with substantially the same terms, including the same economic terms, as the Class M shares. Our bye-laws place certain restrictions on Class A shares such that a holder of Class A shares, except for shareholders permitted by our board of directors, which include members of the Apollo Group, as defined in our bye-laws, cannot control greater than 9.9% of the total outstanding vote and if a holder of Class A shares were to control greater than 9.9% , then a holder’s voting power is automatically reduced to 9.9% and the other holders of Class A shares would vote the remainder on a prorated basis. Share Repurchase Authorization Our board of directors has approved authorizations of $1,567 million for the repurchase of our Class A shares under our repurchase program. We may repurchase shares in open market transactions, in privately negotiated transactions or otherwise. The size and timing of repurchases will depend on legal requirements, market and economic conditions and other factors, and are solely at our discretion. The program has no expiration date, but may be modified, suspended or terminated by the board at any time.

Under the Fee Agreement, effective retroactive to January 1, 2019, 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 U.S. 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, U.S. treasuries, non-preferred equities and alternatives. The following represents assets based on the above sub-allocation structure: (In millions, except percentages) March 31, 2020 Percent of Total December 31, 2019 Percent of Total Core $ 28,858 23.8 % $ 32,474 25.5 % Core Plus 29,717 24.5 % 30,155 23.6 % Yield 44,269 36.4 % 48,557 38.0 % High Alpha 5,390 4.4 % 5,062 4.0 % Other 13,290 10.9 % 11,302 8.9 % Total sub-allocation assets $ 121,524 100.0 % $ 127,550 100.0 % 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 March 31, 2020 and 2019 , we incurred management fees, inclusive of the base and sub-allocation fees, of $128 million and $92 million , respectively. Management fees are included within net investment income on the condensed consolidated statements of income (loss). As of March 31, 2020 and December 31, 2019 , management fees payable were $43 million and $42 million , respectively, and are included in other liabilities on the condensed consolidated balance sheets. 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 (Interest). It is expected that the Interest will be revised such that Mr. Belardi will receive a lesser interest in the equity of ISG and also receive a specified percentage of other fee streams earned by Apollo, potentially comprised of or including the sub-allocation fees. Additionally, six of the fifteen 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 Opportunities, L.P. ( A-A Mortgage) – We have an equity method investment of $508 million and $487 million as of March 31, 2020 and December 31, 2019 , respectively, in A-A Mortgage, which has an investment in AmeriHome. We have a loan purchase agreement with AmeriHome. 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 $169 million and $0 million of residential mortgage loans under this agreement during the three months ended March 31, 2020 and 2019 , respectively. Additionally, we hold ABS securities issued by AmeriHome affiliates of $164 million and $170 million as of March 31, 2020 and December 31, 2019 , respectively, which are included in related party AFS securities on the condensed consolidated balances sheets. We also have commitments to make additional equity investments in A-A Mortgage of $169 million as of March 31, 2020 . MidCap – AAA Investment (Co Invest VII), L.P. (CoInvest VII) holds a significant investment in MidCap, which was $508 million and $547 million as of March 31, 2020 and December 31, 2019 , respectively. CoInvest VII is included in related party investment funds on the condensed consolidated balance sheets and was reflected as a consolidated VIE in prior periods. We have also advanced amounts under a subordinated debt facility to Midcap and, as of March 31, 2020 and December 31, 2019 , the principal balance was $345 million and, net of discounts and allowances, was $330 million and $339 million , respectively, which is included in other related party investments on the condensed consolidated balance sheets. Our total investment in MidCap, including amounts advanced under credit facilities, was $838 million and $886 million as of March 31, 2020 and December 31, 2019 , respectively. Additionally, we hold ABS and CLO securities issued by MidCap affiliates of $524 million and $624 million as of March 31, 2020 and December 31, 2019 , 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 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 March 31, 2020 , 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 $130 million and $132 million as of March 31, 2020 and December 31, 2019 , respectively. Additionally, as of March 31, 2020 and December 31, 2019 , we had $110 million and $146 million , respectively, of funding agreements outstanding to Athora . During the first quarter of 2020, Athora called capital and we remitted $361 million to Athora. We did not receive shares from Athora until April 1, 2020; therefore, we recorded a receivable in other assets on the consolidated balance sheets as of March 31, 2020 for the capital funding. We also have commitments to make additional equity investments in Athora of $364 million as of March 31, 2020 . Venerable – We have coinsurance and modco agreements with Venerable Insurance and Annuity Company (VIAC, formerly Voya Insurance and Annuity Company). VIAC is a related party due to our minority equity investment in its holding company’s parent, VA Capital Company LLC (VA Capital) , which was $110 million and $99 million as of March 31, 2020 and December 31, 2019 , 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 and Reverence Capital Partners, and is the parent of Venerable, which is the parent of VIAC. Additionally, we have a 15-year term loan receivable from Venerable due in 2033, which is included in related party other investments on the condensed consolidated balance sheets. The loan is held at the principal balance less allowances and was $145 million and $148 million as of March 31, 2020 and December 31, 2019 , respectively. While management views the overall transactions with Venerable as favorable to us, the stated interest rate of 6.257% on the term loan to Venerable represents a below-market interest rate, and management considered such rate as part of its evaluation and pricing of the reinsurance transactions. Strategic Partnership – On October 24, 2018, we entered into 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 March 31, 2020 and December 31, 2019 , we had $162 million and $97 million , respectively, of investments under the Strategic Partnership and these investments are included in related party investment funds on the condensed consolidated balance sheets and were reflected as consolidated VIEs in prior periods. PK AirFinance – During the fourth quarter of 2019, we and Apollo purchased PK AirFinance (PK), an aviation lending business, including PK’s in force loan portfolio (Aviation Loans), from the Aviation Services Unit of GE Capital (GE). The Aviation Loans are generally fully secured by aircraft leases and aircraft. In connection with such transaction, Apollo acquired 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 (collectively, PK Transaction Agreements), the existing Aviation Loans were acquired and securitized by a newly formed SPV for which Apollo acts as ABS manager (ABS-SPV). The ABS-SPV issued tranches of senior notes and subordinated notes, which are secured by the Aviation Loans. In connection with the acquisition of the existing Aviation Loans by the ABS-SPV (i) a tranche of senior notes was acquired by third-party investors and (ii) we purchased mezzanine tranches of the senior notes and the subordinated notes. As of March 31, 2020 and December 31, 2019 , our investment in securitizations of loans originated by PK was $1,141 million and $1,282 million , respectively, and are included in related party AFS or trading securities on the condensed consolidated balance sheets. In addition to the investment in the senior notes and subordinated notes, we also have a right to acquire, whether directly, through the ABS-SPV or through a similar vehicle, all Aviation Loans originated by PK (Forward Flow Loans). All servicing and administrative costs and expenses of Apollo (determined at cost, without mark-up) that are incurred in connection with the sourcing, origination, servicing and maintaining the Forward Flow Loans, net of any service fees and servicing and administrative cost and expense reimbursement amounts received directly from the ABS-SPV or other entities investing in the Forward Flow Loans are allocated to, and reimbursed by the ABS-SPV or us, as applicable, subject to an agreed-upon annual cap. In addition to the payment of the expenses described in the preceding paragraph and the base management fee paid to Apollo on all assets managed by Apollo, we have paid or expect to pay the following fees to Apollo or certain service providers that are affiliates of, or are companies managed by, Apollo in connection with the PK Transaction Agreements: (A) To Apollo, sub-allocation fees on the senior notes based on the rates applicable to Yield assets and sub-allocation fees on the subordinated notes based on the rates applicable to High Alpha assets. (B) To Redding Ridge Asset Management LLC, a company in which certain funds managed by Apollo have an interest, as consideration for assistance with the structuring, monitoring, support and maintenance of the securitization transactions, a one-time structuring fee, as well as ongoing support fees equal to 1.5 bps on the total capitalization amount and certain other fees, which may become due upon the occurrence of certain events; and (C) To Merx Aviation Servicing Limited, a company externally managed by Apollo Investment Management, L.P., with respect to certain diligence, technical support and enforcement, remarketing and restructuring services with respect to the existing Aviation Loans and the Forward Flow Loans, a one-time servicing fee, as well as certain special situations fees, which may become due upon the occurrence of certain events. 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. As of March 31, 2020 , ADIP owned 67% of the equity interests, while we retained 100% of the voting power and 33% of the equity interests in ACRA. During the first quarter of 2020, we received capital of $240 million from and paid a dividend of $46 million to ADIP. On April 1, 2020, ALRe purchased 14,000 newly issued ACRA shares for $66 million , which resulted in ALRe holding 36.55% of the economic interests in ACRA. The remaining 63.45% of the economic interests in ACRA are held by 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 . Pursuant to the underlying transaction agreements, among other things (1) AGM has the right to purchase additional Class A common shares until August 26, 2020 to the extent AOG and certain affiliates, employees and consultants of AGM do not beneficially own at least 35% of the issued and outstanding Class A common shares (inclusive of Class A common shares over which any such persons have a valid proxy), on a fully diluted basis, in a number to achieve such 35% ownership level at a price based upon a weighted average price during the 30 days prior to the exercise of the purchase right and (2) 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 current multi-class share structure. Concurrently 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. AA Infrastructure Fund 1 LLC (AA Infrastructure) – We have an investment in preferred shares of AA Infrastructure, which is a fund managed by ISG. As of March 31, 2020 and December 31, 2019 , we held $49 million and $58 million , respectively, of preferred shares, which are included in related party equity securities on the consolidated balance sheets and also held AA Infrastructure ABS securities of $284 million and $267 million , respectively, which are included in related party trading securities on the consolidated balance sheets.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	10. 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 $4,939 million a nd $4,793 million as of March 31, 2020 and December 31, 2019 , 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 March 31, 2020 and December 31, 2019 , we had $1,426 million and $1,226 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 March 31, 2020 and December 31, 2019 , we had $4,325 million and $3,700 million , respectively, of FABN f unding agreements outstanding . We had $5,375 million of remaining FABN capacity as of March 31, 2020 . Pledged Assets and Funds in Trust (Restricted Assets)— The total restricted assets included on the condensed consolidated balance sheets are as follows: (In millions) March 31, 2020 December 31, 2019 AFS securities $ 8,877 $ 9,369 Trading securities 46 45 Equity securities 16 22 Mortgage loans 2,964 2,535 Investment funds 7 84 Derivative assets 60 105 Short-term investments 101 92 Other investments 93 88 Restricted cash 564 402 Total restricted assets $ 12,728 $ 12,742 The restricted assets are primarily related to reinsurance trusts established in accordance with coinsurance agreements, and the FHLB funding agreements described above. Letter of Credit— We have an undrawn letter of credit for $188 million as of March 31, 2020 . This letter of credit was issued for our reinsurance program and expires by December 31, 2020 . 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 March 31, 2020 , had an asset value of $382 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 took the matter under advisement and we expect an opinion in the next few months. 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 value of the guarantees included within the asset value reflected above is $202 million as of March 31, 2020 . Regulatory Matters – Beginning in 2015, our U.S. insurance subsidiaries have 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 on a reduced scale. 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, indicating, in each case, that the respective regulator planned to undertake a market conduct examinations or enforcement proceeding of the applicable U.S. 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 have entered into consent orders with several states, including the NYSDFS, to resolve underlying matters in those 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. Global Atlantic is currently in negotiation with the CDI to resolve the pending joint action related to the converted life insurance policies. In addition to the examinations and proceedings initiated to date, it is possible that other regulators may pursue similar formal examinations, inquiries or enforcement proceedings and that any examinations, inquiries and/or enforcement proceedings may result in fines, administrative penalties and payments to policyholders. While we do not expect the amount of any such fines, penalties or payments arising from these matters to be material to our financial condition, results of operations or cash flows, it is possible that such amounts could be material. 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. On January 23, 2019, we received a letter from the NYSDFS, with respect to a pension risk transfer (PRT) transaction, which expressed concerns with our interpretation and reliance upon certain exemptions from licensing in New York in connection with certain activities performed by employees in our PRT channel, including specific activities performed within New York. On April 13, 2020, we entered into a consent order with the NYSDFS to resolve this matter. Pursuant to the consent order, the NYSDFS imposed a fine of $45 million , which was accrued in other liabilities on the consolidated balance sheets as of December 31, 2019. Caldera Matters – On May 3, 2018, AHL filed a writ commencing litigation in the Supreme Court of Bermuda against a former officer of AHL, a former director of AHL (who is also considered a former officer pursuant to Bermuda law), and Caldera Holdings, Ltd. (Caldera). AHL alleges in the writ, among other things, that the defendants breached various duties owed to AHL under Bermuda law by using AHL’s confidential information in their attempted acquisition of a company referred to in the litigation as Company A. AHL is seeking injunctive relief and damages. Athene amended its writ on October 16, 2018. The trial court denied two separate motions to dismiss made by defendant Caldera on June 28, 2018 and by the former officer and former director defendants on January 14, 2019. On September 20, 2019, the Bermuda Court of Appeal affirmed both trial court rulings and dismissed the defendants’ appeal. Defendants have not further pursued an appeal of this decision to the Judicial Committee of the Privy Council, the court of final appeal for matters litigated in Bermuda. On March 17, 2020, we filed an application for leave to amend the complaint to more broadly assert defendants’ breaches of duties. On May 3, 2018, following AHL’s filing of the writ in Bermuda described above, Caldera, Caldera Life Reinsurance Company, and Caldera Shareholder, L.P., commenced an action in the Supreme Court of the State of New York, County of New York, by filing a Summons with Notice against AHL, Apollo, certain affiliates of Apollo and Leon Black, a founder of Apollo. On July 12, 2018, plaintiffs filed a complaint alleging claims for tortious interference with prospective business relations, defamation, and unfair competition related to plaintiffs’ attempt to purchase Company A and seeking alleged damages of “no less than $1.5 billion .” AHL has moved to dismiss the complaint. On January 21, 2019, plaintiffs filed an amended complaint, which revised certain allegations about jurisdiction, venue and the merits of the plaintiffs’ claims. We have renewed our motion to dismiss and, on December 20, 2019, the court granted our motion to dismiss. Plaintiffs have filed an appeal. We believe we have meritorious defenses to the claims and intend to vigorously defend the litigation. In light of the inherent uncertainties involved in this matter, reasonably possible losses, if any, cannot be estimated at this time.

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, considered necessary for fair statement of the results for the interim periods presented. All significant intercompany accounts and transactions have been eliminated. Interim operating results are not necessarily indicative of the results expected for the entire year, particularly in light of the material risks and uncertainties surrounding the spread of the Coronavirus Disease of 2019 (COVID-19), which has resulted in significant volatility in the financial markets. The condensed consolidated balance sheet as of December 31, 2019 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, 2019
Use of Estimates	The preparation of financial statements requires the use of management estimates. Our estimates may vary as more information about the extent to which COVID-19 and the resulting impact on economic conditions and the financial markets become known. 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 Financial Instruments – Credit Losses (ASU 2019-05, ASU 2019-04, ASU 2018-19 and ASU 2016-13) This update limits the number of credit impairment models used for different assets and results in accelerated credit loss recognition on assets held at amortized cost, which primarily includes our commercial and residential mortgage loans, but also includes certain other loans and reinsurance assets. The identification of PCD financial assets includes all assets that have experienced a more-than-insignificant deterioration in credit since origination. Additionally, changes in the expected cash flows of purchased credit-deteriorated financial assets are recognized immediately in the income statement. AFS securities are not in scope of the new credit loss model, but were subject to targeted improvements including the establishment of a valuation allowance for credit losses versus the previous direct write down approach. We adopted this update effective January 1, 2020 with a cumulative-effect adjustment that decreased retained earnings by $117 million net of tax and offsetting impacts to DAC, DSI, VOBA and the SOP 03-1 reserve. The adjustment to retained earnings primarily relates to the establishment of an allowance on our commercial mortgage loan portfolio, which represented approximately 1.59% of the amortized cost of the portfolio, but also includes immaterial impacts relating to other assets in scope, including residential mortgage loans, funds withheld at interest, and reinsurance recoverable. Additionally, the update requires investments previously considered purchased credit impaired (PCI), which includes certain of our residential mortgage loans and RMBS to become subject to a modified PCD framework at the transition date. Any required allowance at transition for these assets is to be recorded through a gross-up of the amortized cost, rather than a charge to retained earnings. Additionally, under the AFS impairment model, the recording of an allowance is prohibited in instances where fair value exceeds amortized cost as such securities are not considered impaired under the AFS impairment model. Therefore, no allowance was recorded at transition for PCI RMBS that were in an unrealized gain position. The transition increase of amortized cost and corresponding valuation allowance for residential mortgage loans and RMBS was $36 million and $17 million , respectively. Collaborative Arrangements (ASU 2018-18) The amendments in this update provide guidance on whether certain transactions between collaborative arrangement participants should be accounted for as revenue under Topic 606, providing comparability in the presentation of revenue for certain transactions. We adopted this update effective January 1, 2020. This update did not have a material effect on our consolidated financial statements. Consolidation (ASU 2018-17) The amendments in this update expand certain discussions in the VIE guidance, including considerations necessary for determining when a decision-making fee is a variable interest. We adopted this update effective January 1, 2020. The adoption of this update did not have a material effect on our consolidated financial statements. Cloud Computing Arrangements (ASU 2018-15) The amendments in this update align the requirements for capitalizing implementation costs incurred in a cloud computing service arrangement with the requirements for capitalizing implementation costs incurred for internal-use software. We adopted this update on a prospective basis effective January 1, 2020. This update did not have a material effect on our consolidated financial statements. Fair Value Measurement – Disclosure Requirements (ASU 2018-13) The amendments in this update modify the disclosure requirements for fair value measurements by removing, modifying or adding certain disclosures. On October 1, 2018, we early adopted the removal and modification of certain disclosures as permitted. The additional disclosures in the update were adopted effective January 1, 2020. The adoption of this update did not have a material effect on our consolidated financial statements. Intangibles – Simplifying the Test for Goodwill Impairment (ASU 2017-04) The amendments in this update simplify the subsequent measurement of goodwill by eliminating the comparison of the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill to determine the goodwill impairment loss. With the adoption of this guidance, a goodwill impairment is the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of the goodwill allocated to that reporting unit. Entities continue to have the option to perform a qualitative assessment to determine if a quantitative impairment test is necessary. We do not have material goodwill and adopted this update on a prospective basis effective January 1, 2020. The adoption of this update did not have a material effect on our consolidated financial statements. Recently Issued Accounting Pronouncements Insurance – Targeted Improvements to the Accounting for Long-Duration Contracts (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 the guaranteed lifetime withdrawal benefits (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. The amendments in ASU 2018-12 were originally intended to become effective January 1, 2021; however, with the issuance of ASU 2019-09, we will not be required to adopt the amendments until January 1, 2022. 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. 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 will be required to adopt this update January 1, 2021 and apply certain aspects of the update retrospectively while other aspects will be applied on a modified retrospective basis. Early adoption is permitted. We are currently evaluating the impact of this guidance on our consolidated financial statements.
