Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies Consolidation and Basis of Presentation The accompanying consolidated financial statements of American Equity Investment Life Holding Company ("we", "us", "our" or the "Company") have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP") for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X. The consolidated financial statements include a variable interest entity (“VIE”) in which we are the primary beneficiary. All of the adjustments in the consolidated financial statements are normal recurring items which are necessary to present fairly our financial position and results of operations on a basis consistent with the prior audited consolidated financial statements. Operating results for the three and nine month periods ended September 30, 2021 are not necessarily indicative of the results that may be expected for any other period, including for the year ended December 31, 2021. All significant intercompany accounts and transactions have been eliminated. The preparation of financial statements requires management estimates and assumptions using subjective and complex judgments that frequently require assumptions about matters that are inherently uncertain. Our actual results could differ from these estimates. For further information related to a description of areas of judgment and estimates and other information necessary to understand our financial position and results of operations, refer to the audited consolidated financial statements and notes included in our Annual Report on Form 10-K for the year ended December 31, 2020. Real Estate Investments Beginning in the second quarter of 2021, we held residential real estate investments through consolidation of an investment company VIE. Residential real estate investments are reported at fair value and the change in fair value on these investments is reported in net income as a component of net investment income. Fair values of residential real estate are initially based on the cost to purchase the properties and subsequently based on a discounted cash flow methodology. See Note 3 – Fair Values of Financial Instruments for more information on the determination of fair value. The residential real estate investments are leased to renters through operating lease arrangements. Rental income is recognized on a straight-line basis over the term of the respective leases. Variable Interest Entities We have relationships with various special purpose entities and other legal entities that must be evaluated to determine if the entities meet the criteria of a VIE. This assessment is performed by reviewing contractual, ownership and other rights and requires use of judgment. First, we determine if we hold a variable interest in an entity by assessing if we have the right to receive expected losses and expected residual returns of the entity. If we hold a variable interest, then the entity is assessed to determine if it is a VIE. An entity is a VIE if the equity at risk is not sufficient to support its activities, if the equity holders lack a controlling financial interest or if the entity is structured with non-substantive voting rights. In addition to the previous criteria, if the entity is a limited partnership or similar entity, it is a VIE if the limited partners do not have the power to direct the entity’s most significant activities through substantive kick-out rights or participating rights. A VIE is evaluated to determine the primary beneficiary. The primary beneficiary of a VIE is the enterprise with (1) the power to direct the activities of a VIE that most significantly impact the entity's economic performance and (2) the obligation to absorb losses of the entity or the right to receive benefits from the entity that could potentially be significant to the VIE. When we are the primary beneficiary, we are required to consolidate the entity in our financial statements. We reassess our involvement with VIEs on a quarterly basis. For further information about VIEs, refer to Note 6 – Variable Interest Entities. Adopted Accounting Pronouncements There were no accounting pronouncements that were adopted during the current period. In June 2016, the Financial Accounting Standards Board (“FASB”) issued an accounting standards update (“ASU”) that significantly changed the impairment model for most financial assets that are measured at amortized cost and certain other instruments from an incurred loss model to an expected loss model that requires these assets be presented at the net amount expected to be collected. In addition, credit losses on available for sale debt securities are recorded through an allowance account subsequent to the adoption of this ASU. We adopted this ASU on January 1, 2020. The adoption of this ASU resulted in an increase in our mortgage loan allowance for credit losses of $8.6 million and the recognition of an allowance for credit losses on our reinsurance recoverable/coinsurance deposits balances of $3.2 million on the date of adoption. Retained earnings was decreased by $9.3 million, which reflects the net of tax impact of the increase in the mortgage loan allowance for credit losses and the recognition of an allowance for credit losses on our reinsurance recoverable/coinsurance deposits balances on the date of adoption. New Accounting Pronouncements In August 2018, the FASB issued an ASU that revises certain aspects of the measurement models and disclosure requirements for long duration insurance and investment contracts. The FASB’s objective in issuing this ASU is to improve, simplify, and enhance the accounting for long-duration contracts. The revisions include updating cash flow assumptions in the calculation of the liability for traditional life products, introducing the term ‘market risk benefit’ ("MRB") and requiring all contract features meeting the definition of an MRB to be measured at fair value, simplifying the method used to amortize deferred policy acquisition costs and deferred sales inducements to a constant basis over the expected term of the related contracts rather than based on actual and estimated gross profits and enhancing disclosure requirements. While this ASU is effective for us on January 1, 2023, the transition date (the remeasurement date) is January 1, 2021. Early adoption of this ASU is permitted. We are in the process of evaluating the impact this guidance will have on our consolidated financial statements.
