Organization, Consolidation and Presentation of Financial Statements [Abstract]
ORGANIZATION	ORGANIZATION Apollo Global Management, Inc. (“AGM Inc.”, together with its consolidated subsidiaries, the “Company” or “Apollo”) is a global alternative investment manager whose predecessor was founded in 1990. Its primary business is to raise, invest and manage credit, private equity and real assets funds as well as strategic investment accounts, on behalf of pension, endowment and sovereign wealth funds, as well as other institutional and individual investors. For these investment management services, Apollo receives management fees generally related to the amount of assets managed, transaction and advisory fees, incentive fees and performance allocations related to the performance of the respective funds that it manages. Apollo has three primary business segments: • Credit —primarily invests in non-control corporate and structured debt instruments including performing, stressed and distressed investments across the capital structure; • Private equity —primarily invests in control equity and related debt instruments, convertible securities and distressed debt investments; and • Real assets —primarily invests in (i) real estate equity and infrastructure equity for the acquisition and recapitalization of real estate and infrastructure assets, portfolios, platforms and operating companies, (ii) real estate and infrastructure debt including first mortgage and mezzanine loans, preferred equity and commercial mortgage backed securities and (iii) European performing and non-performing loans, and unsecured consumer loans. Organization of the Company Effective September 5, 2019, Apollo Global Management, Inc. converted from a Delaware limited liability company named Apollo Global Management, LLC to a Delaware corporation named Apollo Global Management, Inc. The Company was formed as a Delaware limited liability company on July 3, 2007, and, until the Conversion, was managed by AGM Management, LLC, which is indirectly wholly-owned and controlled by Leon Black, Joshua Harris and Marc Rowan, its Managing Partners. As of September 30, 2019 , the Company owned, through six intermediate holding companies, 55.2% of the economic interests of, and operated and controlled all of the businesses and affairs of, the Apollo Operating Group through its wholly owned subsidiaries. AP Professional Holdings, L.P., a Cayman Islands exempted limited partnership (“Holdings”), is the entity through which the Managing Partners and certain of the Company’s other partners (the “Contributing Partners”) indirectly beneficially own interests in each of the entities that comprise the Apollo Operating Group (“AOG Units”). As of September 30, 2019 , Holdings owned the remaining 44.8% of the economic interests in the Apollo Operating Group. The Company consolidates the financial results of the Apollo Operating Group and its consolidated subsidiaries. Holdings’ ownership interest in the Apollo Operating Group is reflected as a Non-Controlling Interest in the accompanying condensed consolidated financial statements. Conversion to a Corporation On September 4, 2019, AGM LLC notified the New York Stock Exchange (the “NYSE”) that a Certificate of Conversion (the “Certificate of Conversion”) had been filed with the Secretary of State of the State of Delaware. Effective at 12:01 a.m. (Eastern Time) on September 5, 2019 (the “Effective Time”), (i) each Class A share (“Class A Share”) representing limited liability company interests of AGM LLC outstanding immediately prior to the Effective Time converted into one issued and outstanding, fully paid and nonassessable share of Class A common stock, $0.00001 par value per share, of the Company (“Class A Common Stock”), (ii) the Class B share (the “Class B Share”) representing limited liability company interests of AGM LLC outstanding immediately prior to the Effective Time converted into one issued and outstanding, fully paid and nonassessable share of Class B common stock, $0.00001 par value per share, of the Company (the “Class B Common Stock”), (iii) each Series A preferred share (“Series A Preferred Share”) representing limited liability company interests of AGM LLC outstanding immediately prior to the Effective Time converted into one issued and outstanding, fully paid and nonassessable share of Series A preferred stock, having a liquidation preference of $25.00 per share, of the Company (“Series A Preferred Stock”), (iv) each Series B preferred share (“Series B Preferred Share”) representing limited liability company interests of AGM LLC outstanding immediately prior to the Effective Time converted into one issued and outstanding, fully paid and nonassessable share of Series B preferred stock, having a liquidation preference of $25.00 per share, of the Company (“Series B Preferred Stock”) and (v) AGM Management, LLC, a Delaware limited liability company (the “Former Manager”), was granted one issued and outstanding, fully paid and nonassessable share of Class C common stock, $0.00001 par value per share, of the Company (“Class C Common Stock”), which bestows to its holder certain management rights over the Company. Prior to the Effective Time, the Former Manager held all such management powers over the business and affairs of AGM LLC pursuant to the Third Amended and Restated Limited Liability Company Agreement of AGM LLC, dated as of March 19, 2018.

Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying unaudited condensed consolidated financial statements are prepared in accordance with U.S. GAAP for interim financial information and instructions to the Quarterly Report on Form 10-Q. The condensed consolidated financial statements and these notes are unaudited and exclude some of the disclosures required in annual financial statements. Management believes it has made all necessary adjustments (consisting only of normal recurring items) so that the condensed consolidated financial statements are presented fairly and that estimates made in preparing its condensed consolidated financial statements are reasonable and prudent. The operating results presented for interim periods are not necessarily indicative of the results that may be expected for any other interim period or for the entire year. These condensed consolidated financial statements should be read in conjunction with the annual financial statements included in the 2018 Annual Report. The condensed consolidated financial statements include the accounts of the Company, its wholly-owned or majority-owned subsidiaries, the consolidated entities which are considered to be variable interest entities (“VIEs”) and for which the Company is considered the primary beneficiary, and certain entities which are not considered VIEs but which the Company controls through a majority voting interest. Intercompany accounts and transactions, if any, have been eliminated upon consolidation. Certain reclassifications, when applicable, have been made to the prior periods’ condensed consolidated financial statements and notes to conform to the current period’s presentation and are disclosed accordingly. Consolidation The types of entities with which Apollo is involved generally include subsidiaries (e.g., general partners and management companies related to the funds the Company manages), entities that have all the attributes of an investment company (e.g., funds) and securitization vehicles (e.g., CLOs). Each of these entities is assessed for consolidation on a case by case basis depending on the specific facts and circumstances surrounding that entity. Pursuant to the consolidation guidance, the Company first evaluates whether it holds a variable interest in an entity. Fees that are customary and commensurate with the level of services provided, and where the Company does not hold other economic interests in the entity that would absorb more than an insignificant amount of the expected losses or returns of the entity, would not be considered a variable interest. Apollo factors in all economic interests including proportionate interests through related parties, to determine if such interests are considered a variable interest. As Apollo’s interests in many of these entities are solely through market rate fees and/or insignificant indirect interests through related parties, Apollo is not considered to have a variable interest in many of these entities and no further consolidation analysis is performed. For entities where the Company has determined that it does hold a variable interest, the Company performs an assessment to determine whether each of those entities qualify as a VIE. The determination as to whether an entity qualifies as a VIE depends on the facts and circumstances surrounding each entity and therefore certain of Apollo’s funds may qualify as VIEs under the variable interest model whereas others may qualify as voting interest entities (“VOEs”) under the voting interest model. The granting of substantive kick-out rights is a key consideration in determining whether a limited partnership or similar entity is a VIE and whether or not that entity should be consolidated. Under the variable interest model, Apollo consolidates those entities where it is determined that the Company is the primary beneficiary of the entity. The Company is determined to be the primary beneficiary when it has a controlling financial interest in the VIE, which is defined as possessing both (i) the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and (ii) the obligation to absorb losses of the VIE or the right to receive benefits from the VIE that could potentially be significant to the VIE. When Apollo alone is not considered to have a controlling financial interest in the VIE but Apollo and its related parties under common control in the aggregate have a controlling financial interest in the VIE, Apollo will be deemed the primary beneficiary if it is the party that is most closely associated with the VIE. When Apollo and its related parties not under common control in the aggregate have a controlling financial interest in the VIE, Apollo would be deemed to be the primary beneficiary if substantially all the activities of the entity are performed on behalf of Apollo. Apollo determines whether it is the primary beneficiary of a VIE at the time it becomes initially involved with the VIE and reconsiders that conclusion continuously. Investments and redemptions (either by Apollo, related parties of Apollo or third parties) or amendments to the governing documents of the respective entity may affect an entity’s status as a VIE or the determination of the primary beneficiary. Assets and liabilities of the consolidated VIEs are primarily shown in separate sections within the condensed consolidated statements of financial condition. Changes in the fair value of the consolidated VIEs’ assets and liabilities and related interest, dividend and other income and expenses are presented within net gains from investment activities of consolidated variable interest entities in the condensed consolidated statements of operations. The portion attributable to Non-Controlling Interests is reported within net income attributable to Non-Controlling Interests in the condensed consolidated statements of operations. For additional disclosures regarding VIEs, see note 5 . Under the voting interest model, Apollo consolidates those entities it controls through a majority voting interest. Apollo does not consolidate those VOEs in which substantive kick-out rights have been granted to the unrelated investors to either dissolve the fund or remove the general partner. Cash and Cash Equivalents Apollo considers all highly liquid short-term investments with original maturities of three months or less when purchased to be cash equivalents. Cash and cash equivalents include money market funds and U.S. Treasury securities with original maturities of three months or less when purchased. Interest income from cash and cash equivalents is recorded in interest income in the condensed consolidated statements of operations. The carrying values of the money market funds and U.S. Treasury securities were $302.3 million and $231.8 million as of September 30, 2019 and December 31, 2018 , respectively, which approximate their fair values due to their short-term nature and are categorized as Level I within the fair value hierarchy. Substantially all of the Company’s cash on deposit is in interest bearing accounts with major financial institutions and exceed insured limits. Restricted Cash Restricted cash includes cash held in reserve accounts used to make required payments in respect of the 2039 Senior Secured Guaranteed Notes. Restricted cash also includes cash deposited at a bank, which is pledged as collateral in connection with leased premises. U.S. Treasury securities, at fair value U.S. Treasury securities, at fair value includes U.S. Treasury bills with original maturities greater than three months when purchased. These securities are recorded at fair value. Interest income on such securities is separately presented from the overall change in fair value and is recognized in interest income in the condensed consolidated statements of operations. Any remaining change in fair value of such securities, that is not recognized as interest income, is recognized in net gains (losses) from investment activities in the condensed consolidated statements of operations. Fair Value of Financial Instruments Apollo has elected the fair value option for the Company’s investment in Athene Holding, the assets and liabilities of certain of its consolidated VIEs (including CLOs), the Company’s U.S. Treasury securities with original maturities greater than three months when purchased, and certain of the Company’s other investments. Such election is irrevocable and is applied to financial instruments on an individual basis at initial recognition. The fair value of a financial instrument is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date under current market conditions. Except for the Company’s debt obligations, financial instruments are generally recorded at fair value or at amounts whose carrying values approximate fair value. The actual realized gains or losses will depend on, among other factors, future operating results, the value of the assets and market conditions at the time of disposition, any related transaction costs and the timing and manner of sale, all of which may ultimately differ significantly from the assumptions on which the valuations were based. Fair Value Hierarchy U.S. GAAP establishes a hierarchical disclosure framework which prioritizes and ranks the level of market price observability used in measuring financial instruments at fair value. Market price observability is affected by a number of factors, including the type of financial instrument, the characteristics specific to the financial instrument and the state of the marketplace, including the existence and transparency of transactions between market participants. Financial instruments with readily available quoted prices in active markets generally will have a higher degree of market price observability and a lesser degree of judgment used in measuring fair value. Financial instruments measured and reported at fair value are classified and disclosed based on the observability of inputs used in the determination of fair values, as follows: Level I - Quoted prices are available in active markets for identical financial instruments as of the reporting date. The types of financial instruments included in Level I include listed equities and debt. The Company does not adjust the quoted price for these financial instruments, even in situations where the Company holds a large position and the sale of such position would likely deviate from the quoted price. Level II - Pricing inputs are other than quoted prices in active markets, which are either directly or indirectly observable as of the reporting date, and fair value is determined through the use of models or other valuation methodologies. Financial instruments that are generally included in this category include corporate bonds and loans, less liquid and restricted equity securities and certain over-the-counter derivatives where the fair value is based on observable inputs. These financial instruments exhibit higher levels of liquid market observability as compared to Level III financial instruments. Level III - Pricing inputs are unobservable for the financial instrument and includes situations where there is little observable market activity for the financial instrument. The inputs into the determination of fair value may require significant management judgment or estimation. Financial instruments that are included in this category generally include general and limited partner interests in corporate private equity and real assets funds, opportunistic credit funds, distressed debt and non-investment grade residual interests in securitizations and CDOs and CLOs where the fair value is based on observable inputs as well as unobservable inputs. When a security is valued based on broker quotes, the Company subjects those quotes to various criteria in making the determination as to whether a particular financial instrument would qualify for classification as Level II or Level III. These criteria include, but are not limited to, the number and quality of the broker quotes, the standard deviations of the observed broker quotes, and the percentage deviation from independent pricing services. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, a financial instrument’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the financial instrument when the fair value is based on unobservable inputs. Equity Method Investments For investments in entities over which the Company exercises significant influence but which do not meet the requirements for consolidation and for which the Company has not elected the fair value option, the Company uses the equity method of accounting, whereby the Company records its share of the underlying income or loss of such entities. The Company’s share of the underlying net income or loss of such entities is recorded in principal investment income in the condensed consolidated statements of operations. The carrying amounts of equity method investments are recorded in investments in the condensed consolidated statements of financial condition. As the underlying entities that the Company manages and invests in are, for U.S. GAAP purposes, primarily investment companies which reflect their investments at estimated fair value, the carrying value of the Company’s equity method investments in such entities approximates fair value. Financial Instruments held by Consolidated VIEs The Company measures both the financial assets and financial liabilities of the consolidated CLOs in its condensed consolidated financial statements using the fair value of the financial assets of the consolidated CLOs, which are more observable than the fair value of the financial liabilities of the consolidated CLOs. As a result, the financial assets of the consolidated CLOs are measured at fair value and the financial liabilities are measured in consolidation as: (i) the sum of the fair value of the financial assets and the carrying value of any non-financial assets that are incidental to the operations of the CLOs less (ii) the sum of the fair value of any beneficial interests retained by the Company (other than those that represent compensation for services) and the Company’s carrying value of any beneficial interests that represent compensation for services. The resulting amount is allocated to the individual financial liabilities (other than the beneficial interest retained by the Company) using a reasonable and consistent methodology. Under the measurement alternative, net income attributable to Apollo Global Management, Inc. reflects the Company’s own economic interests in the consolidated CLOs including (i) changes in the fair value of the beneficial interests retained by the Company and (ii) beneficial interests that represent compensation for collateral management services. The consolidated VIEs hold investments that could be traded over-the-counter. Investments in securities that are traded on a securities exchange or comparable over-the-counter quotation systems are valued based on the last reported sale price at that date. If no sales of such investments are reported on such date, and in the case of over-the-counter securities or other investments for which the last sale date is not available, valuations are based on independent market quotations obtained from market participants, recognized pricing services or other sources deemed relevant, and the prices are based on the average of the “bid” and “ask” prices, or at ascertainable prices at the close of business on such day. Market quotations are generally based on valuation pricing models or market transactions of similar securities adjusted for security-specific factors such as relative capital structure priority and interest and yield risks, among other factors. When market quotations are not available, a model based approach is used to determine fair value. Leases The Company determines if an arrangement is a lease or contains a lease at inception. Operating leases are included in lease assets and lease liabilities in the condensed consolidated statements of financial condition. The Company does not have any finance leases. Lease assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Lease assets and lease liabilities are recognized at the date of commencement of the lease (the “commencement date”) based on the present value of lease payments over the lease term. As most of the Company’s leases do not provide an implicit rate, the Company uses its derived incremental borrowing rate based on information available at commencement date in determining the present value of lease payments. The determination of an appropriate incremental borrowing rate requires judgment. The Company determined its incremental borrowing rate based on consideration of market conditions, the Company’s overall creditworthiness, and recent debt and preferred equity issuances. The Company adjusts its rate accordingly based on the term of the leases. Lease assets also include any lease payments made (e.g. pre-paid rent) and are reduced by any deferred rent liabilities arising from lease escalation provisions and lease incentives within the Company’s lease agreements. Accordingly, as of September 30, 2019 , the difference between lease assets and lease liabilities represents the Company’s deferred rent liabilities that are netted against the lease asset amount. Certain lease agreements contain lease escalation or lease incentive provisions based on the terms of the arrangement with the landlord. Lease escalations and lease incentives, if any, are recognized on a straight-line basis over the lease term. The Company’s lease agreements may also include options to extend or terminate the lease. Options to extend would not be included in the lease term until it is reasonably certain that the Company will exercise that option. Lease expense is recognized on a straight-line basis over the lease term and is recorded within general, administrative and other in the condensed consolidated statements of operations. The Company has lease agreements with non-lease components (e.g. estimated operating expenses associated with the lease), which are accounted for separately. Other Assets Other assets primarily includes fixed assets, net, deferred equity-based compensation and prepaid expenses. During 2019, the presentation of intangible assets, net was combined with other assets on the condensed consolidated statements of financial condition and the prior period was recast to conform to the current presentation. Deferred Revenue Apollo records deferred revenue, which is a type of contract liability, when consideration is received in advance of management services provided. Apollo also earns management fees subject to the Management Fee Offset (described below). When advisory and transaction fees are earned by the management company, the Management Fee Offset reduces the management fee obligation of the fund. When the Company receives cash for advisory and transaction fees, a certain percentage of such advisory and/or transaction fees, as applicable, is allocated as a credit to reduce future management fees, otherwise payable by such fund. Such credit is recorded as deferred revenue in the condensed consolidated statements of financial condition. A portion of any excess advisory and transaction fees may be required to be returned to the limited partners of certain funds upon such fund’s liquidation. As the management fees earned by the Company are presented on a gross basis, any Management Fee Offsets calculated are presented as a reduction to advisory and transaction fees in the condensed consolidated statements of operations. Additionally, Apollo earns advisory fees pursuant to the terms of the advisory agreements with certain of the portfolio companies that are owned by the funds Apollo manages. When Apollo receives a payment from a portfolio company that exceeds the advisory fees earned at that point in time, the excess payment is recorded as deferred revenue in the condensed consolidated statements of financial condition. The advisory agreements with the portfolio companies vary in duration and the associated fees are received monthly, quarterly or annually. Deferred revenue is reversed and recognized as revenue over the period that the agreed upon services are performed. There was $77.1 million of revenue recognized during the nine months ended September 30, 2019 that was previously deferred as of January 1, 2019. Under the terms of the funds’ partnership agreements, Apollo is normally required to bear organizational expenses over a set dollar amount and placement fees or costs in connection with the offering and sale of interests in the funds it manages to investors. The placement fees are payable to placement agents, who are independent third parties that assist in identifying potential investors, securing commitments to invest from such potential investors, preparing or revising offering and marketing materials, developing strategies for attempting to secure investments by potential investors and/or providing feedback and insight regarding issues and concerns of potential investors, when a limited partner either commits or funds a commitment to a fund. In certain instances the placement fees are paid over a period of time. Based on the management agreements with the funds, Apollo considers placement fees and organizational costs paid in determining if cash has been received in excess of the management fees earned. Placement fees and organizational costs are normally the obligation of Apollo but can be paid for by the funds. When these costs are paid by the fund, the resulting obligations are included within deferred revenue. The deferred revenue balance will also be reduced during future periods when management fees are earned but not paid. Revenues The Company’s revenues are reported in four separate categories that include (i) management fees; (ii) advisory and transaction fees, net; (iii) investment income, which is comprised of performance allocations and principal investment income; and (iv) incentive fees. On January 1, 2018, the Company adopted new revenue guidance issued by the FASB for recognizing revenue from contracts with customers. The new revenue guidance requires that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services (i.e., the transaction price). When determining the transaction price under the new revenue guidance, an entity may recognize variable consideration only to the extent that it is probable to not be significantly reversed. The new revenue guidance also requires improved disclosures to help users of financial statements better understand the nature, amount, timing, and uncertainty of revenue that is recognized. The Company has concluded that its management fees, advisory and transaction fees, and incentive fees are within the scope of the new revenue guidance. For incentive fees, the new revenue guidance delays the timing of certain revenues compared to the prior accounting treatment. These amounts were previously recognized in carried interest income in the condensed consolidated statements of operations and are now recognized within a separate line, incentive fees. Effective January 1, 2018, the Company implemented a change in accounting principle for performance allocations to be accounted for under guidance applicable to equity method investments, and therefore not within the scope of the new revenue guidance. The accounting change does not change the timing or amount of revenue recognized related to performance allocation arrangements. These amounts were previously recognized within carried interest income in the condensed consolidated statements of operations and carried interest receivable within the condensed consolidated statements of financial condition. As a result of the change in accounting principle, the Company recognizes performance allocations within investment income along with the related principal investment income (as further described below) in the condensed consolidated statements of operations and within the investments line in the condensed consolidated statements of financial condition. The Company applied this change in accounting principle on a full retrospective basis. Management Fees Management fees are recognized over time during the periods in which the related services are performed in accordance with the contractual terms of the related agreement. Management fees are generally based on (1) a percentage of the capital committed during the commitment period, and thereafter based on the remaining invested capital of unrealized investments, or (2) net asset value, gross assets or as otherwise defined in the respective agreements. Included in management fees are certain expense reimbursements where the Company is considered the principal under the agreements and is required to record the expense and related reimbursement revenue on a gross basis. Advisory and Transaction Fees, Net Advisory fees, including management consulting fees and directors’ fees, are generally recognized over time as the underlying services are provided in accordance with the contractual terms of the related agreement. The Company receives such fees in exchange for ongoing management consulting services provided to portfolio companies of funds it manages. Transaction fees, including structuring fees and arranging fees are generally recognized at a point in time when the underlying services rendered are complete. The amounts due from fund portfolio companies are recorded in due from related parties, which is discussed further in note 14 . Under the terms of the limited partnership agreements for certain funds, the management fee payable by the funds may be subject to a reduction based on a certain percentage of such advisory and transaction fees, net of applicable broken deal costs (“Management Fee Offset”). Advisory and transaction fees are presented net of the Management Fee Offset in the condensed consolidated statements of operations. Underwriting fees, which are also included within advisory and transaction fees, net, include gains, losses and fees, arising from securities offerings in which one of the Company’s subsidiaries participates in the underwriter syndicate. Underwriting fees are recognized at a point in time when the underwriting is completed. Underwriting fees recognized but not received are recorded in other assets on the condensed consolidated statements of financial condition. During the normal course of business, the Company incurs certain costs related to certain transactions that are not consummated (“broken deal costs”). These costs (e.g., research costs, due diligence costs, professional fees, legal fees and other related items) are determined to be broken deal costs upon management’s decision to no longer pursue the transaction. In accordance with the related fund agreement, in the event the deal is deemed broken, all of the costs are reimbursed by the funds and then included as a component of the calculation of the Management Fee Offset. If a deal is successfully completed, Apollo is reimbursed by the fund or fund’s portfolio company for all costs incurred and no offset is generated. As the Company acts as an agent for the funds it manages, any transaction costs incurred and paid by the Company on behalf of the respective funds relating to successful or broken deals are recorded net on the Company’s condensed consolidated statements of operations, and any receivable from the respective funds is recorded in due from related parties on the condensed consolidated statements of financial condition. Investment Income Investment income is comprised of performance allocations and principal investment income. Performance Allocations Performance allocations are a type of performance revenue (i.e., income earned based on the extent to which an entity’s performance exceeds predetermined thresholds). Performance allocations are generally structured from a legal standpoint as an allocation of capital in which the Company’s capital account receives allocations of the returns of an entity when those returns exceed predetermined thresholds. The determination of which performance revenues are considered performance allocations is primarily based on the terms of an agreement with the entity. As noted above, as a result of a change in accounting principle, the Company recognizes performance allocations within investment income along with the related principal investment income (as described further below) in the condensed consolidated statements of operations and within the investments line in the condensed consolidated statements of financial condition. Principal Investment Income Principal investment income includes the Company’s income or loss from equity method investments and certain other investments in entities in which the Company is generally eligible to receive performance allocations. Income from equity method investments includes the Company’s share of net income or loss generated from its investments, which are not consolidated, but in which the Company exerts significant influence. Prior to the change in accounting principle noted above, income from equity method investments was included within other income (loss) in the condensed consolidated statements of operations. All prior periods have been conformed to reflect this change in presentation. Incentive Fees Incentive fees are a type of performance revenue. Incentive fees differ from performance allocations in that incentive fees do not represent an allocation of capital but rather a contractual fee arrangement with the entity. Incentive fees are considered a form of variable consideration under the new revenue recognition guidance as they are subject to clawback or reversal and therefore must be deferred until the fees are probable to not be significantly reversed. Accrued but unpaid incentive fees are reported within incentive fees receivable in the Company’s condensed consolidated statements of financial condition. As noted earlier, prior to the adoption of the new revenue recognition guidance, incentive fees were recognized on an assumed liquidation basis. The Company’s incentive fees primarily relate to the credit segment and are generally received from CLOs, managed accounts and AINV. Compensation and Benefits Equity-Based Compensation Equity-based awards granted to employees and non-employees as compensation are measured based on the grant date fair value of the award. Equity-based awards that do not require future service (i.e., vested awards) are expensed immediately. Equity-based employee awards that require future service are expensed over the relevant service period. In addition, certain restricted share units (“RSUs”) granted by the Company vest based on both continued service and the Company’s receipt of performance revenues, within prescribed periods, sufficient to cover the associated equity-based compensation expense. In accordance with U.S. GAAP, equity-based compensation expense for such awards, if and when granted, will be recognized on an accelerated recognition method over the requisite service period to the extent the performance revenue metrics are met or deemed probable. The Company accounts for forfeitures of equity-based awards when they occur. Profit Sharing Profit sharing expense and profit sharing payable primarily consist of a portion of performance revenues earned from certain funds that are allocated to employees, former employees and Contributing Partners. Profit sharing amounts are recognized as the related performance revenues are earned. Accordingly, profit sharing amounts can be reversed during periods when there is a decline in performance revenues that were previously recognized. Profit sharing amounts are generally not paid until the related performance revenue is distributed to the general partner upon realization of the fund’s investme

Organization, Consolidation and Presentation of Financial Statements [Abstract]
VARIABLE INTEREST ENTITIES	VARIABLE INTEREST ENTITIES As described in note 2 , the Company consolidates entities that are VIEs for which the Company has been designated as the primary beneficiary. There is no recourse to the Company for the consolidated VIEs’ liabilities. Consolidated Variable Interest Entities Apollo has consolidated VIEs in accordance with the policy described in note 2 . Through its role as investment manager of these VIEs, the Company determined that Apollo has the power to direct the activities that most significantly impact the economic performance of these VIEs. Additionally, Apollo determined that its interests, both directly and indirectly from these VIEs, represent rights to returns that could potentially be significant to such VIEs. As a result, Apollo determined that it is the primary beneficiary and therefore should consolidate the VIEs. Certain CLOs are consolidated by Apollo as the Company is considered to hold a controlling financial interest through direct and indirect interests in these CLOs exclusive of management and performance-based fees received. Through its role as collateral manager of these VIEs, the Company determined that Apollo has the power to direct the activities that most significantly impact the economic performance of these VIEs. These CLOs were formed for the sole purpose of issuing collateralized notes to investors. The assets of these VIEs are primarily comprised of senior secured loans and the liabilities are primarily comprised of debt. The assets of consolidated CLOs are not available to creditors of the Company. In addition, the investors in these consolidated CLOs have no recourse against the assets of the Company. The Company measures both the financial assets and the financial liabilities of the CLOs using the fair value of the financial assets as further described in note 2 . The Company has elected the fair value option for financial instruments held by its consolidated CLOs, which includes investments in loans and corporate bonds, as well as debt obligations and contingent obligations held by such consolidated CLOs. Other assets include amounts due from brokers and interest receivables. Other liabilities include payables for securities purchased, which represent open trades within the consolidated CLOs and primarily relate to corporate loans that are expected to settle within 60 days . As of September 30, 2019 and December 31, 2018 , the Company held investments of $42.2 million and $44.2 million , respectively, in consolidated foreign currency denominated CLOs, which eliminate in consolidation. Net Gains from Investment Activities of Consolidated Variable Interest Entities The following table presents net gains from investment activities of the consolidated VIEs: For the Three Months Ended For the Nine Months Ended 2019 (1) 2018 (1) 2019 (1) 2018 (1) Net gains from investment activities $ 14,892 $ 17,898 $ 38,679 $ 23,211 Net gains (losses) from debt (5,217 ) (6,131 ) (16,287 ) 2,043 Interest and other income 7,357 8,391 20,772 27,118 Interest and other expenses (6,401 ) (7,157 ) (18,436 ) (23,626 ) Net gains from investment activities of consolidated variable interest entities $ 10,631 $ 13,001 $ 24,728 $ 28,746 (1) Amounts reflect consolidation eliminations. Senior Secured Notes, Subordinated Notes and Secured Borrowings Included within debt are amounts due to third-party institutions by the consolidated VIEs. The following table summarizes the principal provisions of the debt of the consolidated VIEs: As of September 30, 2019 As of December 31, 2018 Principal Outstanding Weighted Average Interest Rate Weighted Average Remaining Maturity in Years Principal Outstanding Weighted Average Interest Rate Weighted Average Remaining Maturity in Years Senior Secured Notes (2) $ 730,820 1.67 % 10.4 $ 768,860 1.67 % 11.2 Subordinated Notes (2) 90,951 N/A (1) 20.7 95,686 N/A (1) 21.4 Secured Borrowings (2)(3) 18,976 3.82 % 8.1 18,976 3.42 % 8.8 Total $ 840,747 $ 883,522 (1) The subordinated notes do not have contractual interest rates but instead receive distributions from the excess cash flows of the VIEs. (2) The debt of the consolidated VIEs is collateralized by assets of the consolidated VIEs and assets of one vehicle may not be used to satisfy the liabilities of another vehicle. The fair value of the debt and collateralized assets of the Senior Secured Notes, Subordinated Notes and Secured Borrowings are presented below: As of September 30, 2019 As of December 31, 2018 Debt, at fair value $ 828,824 $ 855,461 Collateralized assets $ 1,244,868 $ 1,290,891 (3) Secured borrowings consist of a consolidated VIE’s obligation through a repurchase agreement redeemable at maturity with a third party lender. The fair value of the secured borrowings as of September 30, 2019 and December 31, 2018 was $19.0 million and $19.0 million , respectively. The consolidated VIEs’ debt obligations contain various customary loan covenants. As of September 30, 2019 , the Company was not aware of any instances of non-compliance with any of these covenants. As of September 30, 2019 , the contractual maturities for debt of the consolidated VIEs is greater than 5 years . Variable Interest Entities Which are Not Consolidated The Company holds variable interests in certain VIEs which are not consolidated, as it has been determined that Apollo is not the primary beneficiary. The following table presents the carrying amounts of the assets and liabilities of the VIEs for which Apollo has concluded that it holds a significant variable interest, but that it is not the primary beneficiary. In addition, the table presents the maximum exposure to losses relating to these VIEs.

The following tables summarize the quantitative inputs and assumptions used for financial assets and liabilities categorized as Level III under the fair value hierarchy: As of September 30, 2019 Fair Value Valuation Techniques Unobservable Inputs Ranges Weighted Average Financial Assets Other investments $ 5,319 Third Party Pricing N/A N/A N/A 107,311 Discounted cash flow Discount rate 15.0% - 16.0% 15.6% Investments of consolidated VIEs: Equity securities 298,405 Book value multiple Book value multiple 0.58x 0.58x Discounted cash flow Discount rate 11.9% 11.9% Total Financial Assets $ 411,035 Financial Liabilities Contingent consideration obligation $ 96,400 Discounted cash flow Discount rate 17.0% 17.0% Total Financial Liabilities $ 96,400 As of December 31, 2018 Fair Value Valuation Techniques Unobservable Inputs Ranges Weighted Average Financial Assets Other investments $ 6,901 Third Party Pricing N/A N/A N/A 89,469 Discounted cash flow Discount Rate 15.0% - 16.0% 15.5% Investments of consolidated VIEs: Corporate loans/bonds/CLO notes 4,116 Third party pricing N/A N/A N/A Equity securities 291,871 Book value multiple Book value multiple 0.65x 0.65x Discounted cash flow Discount rate 15.2% 15.2% Total investments of consolidated VIEs 295,987 Total Financial Assets $ 392,357 Financial Liabilities Contingent consideration obligation $ 74,487 Discounted cash flow Discount rate 17.0% 17.0% Total Financial Liabilities $ 74,487 Fair Value Measurement of Investment in Athene Holding As of September 30, 2019 and December 31, 2018 , the fair value of Apollo’s Level I investment in Athene Holding was calculated using the closing market price of Athene Holding shares of $42.06 and $39.83 , respectively. Discounted Cash Flow Model When a discounted cash flow model is used to determine fair value, the significant input used in the valuation model is the discount rate applied to present value the projected cash flows. Increases in the discount rate can significantly lower the fair value of an investment and the contingent consideration obligations; conversely decreases in the discount rate can significantly increase the fair value of an investment and the contingent consideration obligations. Consolidated VIEs Investments As of September 30, 2019 and December 31, 2018 , the significant unobservable inputs used in the fair value measurement of the equity securities include the discount rate applied and the book value multiples applied in the valuation models. These unobservable inputs in isolation can cause significant increases or decreases in fair value. The discount rate is determined based on the market rates an investor would expect for a similar investment with similar risks. When a comparable multiple model is used to determine fair value, the comparable multiples are generally multiplied by the underlying companies’ earnings before interest, taxes, depreciation and amortization (“EBITDA”) to establish the total enterprise value of the company. The comparable multiple is determined based on the implied trading multiple of public industry peers. Liabilities As of September 30, 2019 and December 31, 2018 , the debt obligations of the consolidated CLOs were measured on the basis of the fair value of the financial assets of the CLOs as the financial assets were determined to be more observable and, as a result, categorized as Level II in the fair value hierarchy. Contingent Consideration Obligations The significant unobservable input used in the fair value measurement of the contingent consideration obligations is the discount rate applied in the valuation models. This input in isolation can cause significant increases or decreases in fair value. The discount rate was based on the hypothetical cost of equity in connection with the acquisition of Stone Tower. See note 15 for further discussion of the contingent consideration obligations. Valuation of Underlying Investments of Equity Method Investees As discussed previously, the underlying entities that the Company manages and invests in are primarily investment companies which account for their investments at estimated fair value. On a quarterly basis, Apollo utilizes valuation committees consisting of members from senior management, to review and approve the valuation results related to the investments of the funds it manages. For certain publicly traded vehicles managed by the Company, a review is performed by an independent board of directors. The Company also retains independent valuation firms to provide third-party valuation consulting services to Apollo, which consist of certain limited procedures that management identifies and requests them to perform. The limited procedures provided by the independent valuation firms assist management with validating their valuation results or determining fair value. The Company performs various back-testing procedures to validate their valuation approaches, including comparisons between expected and observed outcomes, forecast evaluations and variance analyses. However, because of the inherent uncertainty of valuation, those estimated values may differ significantly from the values that would have been used had a ready market for the investments existed, and the differences could be material. Credit Investments The majority of investments in Apollo’s credit funds are valued based on quoted market prices and valuation models. Quoted market prices are valued based on the average of the “bid” and the “ask” quotes provided by multiple brokers wherever possible without any adjustments. Apollo will designate certain brokers to use to value specific securities. In order to determine the designated brokers, Apollo considers the following: (i) brokers with which Apollo has previously transacted, (ii) the underwriter of the security and (iii) active brokers indicating executable quotes. In addition, when valuing a security based on broker quotes wherever possible Apollo tests the standard deviation amongst the quotes received and the variance between the concluded fair value and the value provided by a pricing service. When broker quotes are not available Apollo considers the use of pricing service quotes or other sources to mark a position. When relying on a pricing service as a primary source, Apollo (i) analyzes how the price has moved over the measurement period, (ii) reviews the number of brokers included in the pricing service’s population and (iii) validates the valuation levels with Apollo’s pricing team and traders. Debt and equity securities that are not publicly traded or whose market prices are not readily available are valued at fair value utilizing a model based approach to determine fair value. Valuation approaches used to estimate the fair value of illiquid credit investments also may include the market approach and the income approach, as previously described above. The valuation approaches used consider, as applicable, market risks, credit risks, counterparty risks and foreign currency risks. Private Equity Investments The majority of the illiquid investments within our private equity funds are valued using the market approach, which provides an indication of fair value based on a comparison of the subject company to comparable publicly traded companies and transactions in the industry. Market Approach The market approach is driven by current market conditions, including actual trading levels of similar companies and, to the extent available, actual transaction data of similar companies. Judgment is required by management when assessing which companies are similar to the subject company being valued. Consideration may also be given to any of the following factors: (1) the subject company’s historical and projected financial data; (2) valuations given to comparable companies; (3) the size and scope of the subject company’s operations; (4) the subject company’s individual strengths and weaknesses; (5) expectations relating to the market’s receptivity to an offering of the subject company’s securities; (6) applicable restrictions on transfer; (7) industry and market information; (8) general economic and market conditions; and (9) other factors deemed relevant. Market approach valuation models typically employ a multiple that is based on one or more of the factors described above. Enterprise value as a multiple of EBITDA is common and relevant for most companies and industries, however, other industry specific multiples are employed where available and appropriate. Sources for gaining additional knowledge related to comparable companies include public filings, annual reports, analyst research reports, and press releases. Once a comparable company set is determined, Apollo reviews certain aspects of the subject company’s performance and determines how its performance compares to the group and to certain individuals in the group. Apollo compares certain measurements such as EBITDA margins, revenue growth over certain time periods, leverage ratios and growth opportunities. In addition, Apollo compares our entry multiple and its relation to the comparable set at the time of acquisition to understand its relation to the comparable set on each measurement date. Income Approach For investments where the market approach does not provide adequate fair value information, Apollo relies on the income approach. The income approach is also used to validate the market approach within our private equity funds. The income approach provides an indication of fair value based on the present value of cash flows that a business or security is expected to generate in the future. The most widely used methodology for the income approach is a discounted cash flow method. Inherent in the discounted cash flow method are significant assumptions related to the subject company’s expected results, the determination of a terminal value and a calculated discount rate, which is normally based on the subject company’s weighted average cost of capital, or “WACC.” The WACC represents the required rate of return on total capitalization, which is comprised of a required rate of return on equity, plus the current tax-effected rate of return on debt, weighted by the relative percentages of equity and debt that are typical in the industry. The most critical step in determining the appropriate WACC for each subject company is to select companies that are comparable in nature to the subject company and the credit quality of the subject company. Sources for gaining additional knowledge about the comparable companies include public filings, annual reports, analyst research reports, and press releases. The general formula then used for calculating the WACC considers the after-tax rate of return on debt capital and the rate of return on common equity capital, which further considers the risk-free rate of return, market beta, market risk premium and small stock premium, if applicable. The variables used in the WACC formula are inferred from the comparable market data obtained. The Company evaluates the comparable companies selected and concludes on WACC inputs based on the most comparable company or analyzes the range of data for the investment. Debt securities that are not publicly traded or whose market prices are not readily available are valued at fair value utilizing a model based approach to determine fair value. Valuation approaches used to estimate the fair value of hybrid capital investments also may include the market approach and the income approach, as previously described above. The valuation approaches used consider, as applicable, market risks, credit risks, counterparty risks and foreign currency risks. The value of liquid investments, where the primary market is an exchange (whether foreign or domestic), is determined using period end market prices. Such prices are generally based on the close price on the date of determination. Real Assets Investments The estimated fair value of commercial mortgage-backed securities (“CMBS”) in Apollo’s real assets funds is determined by reference to market prices provided by certain dealers who make a market in these financial instruments. Broker quotes are only indicative of fair value and may not necessarily represent what the funds would receive in an actual trade for the applicable instrument. Additionally, the loans held-for-investment are stated at the principal amount outstanding, net of deferred loan fees and costs for certain investments. The loans in Apollo’s real assets funds are evaluated for possible impairment on a quarterly basis. For Apollo’s real assets funds, valuations of non-marketable underlying investments are determined using methods that include, but are not limited to (i) discounted cash flow estimates or comparable analysis prepared internally, (ii) third party appraisals or valuations by qualified real estate appraisers and (iii) contractual sales value of investments/properties subject to bona fide purchase contracts. Methods (i) and (ii) also incorporate consideration of the use of the income, cost, or sales comparison approaches of estimating property values. Certain of the credit, private equity, and real assets funds may also enter into foreign currency exchange contracts, total return swap contracts, credit default swap contracts, and other derivative contracts, which may include options, caps, collars and floors. Foreign currency exchange contracts are marked-to-market by recognizing the difference between the contract exchange rate and the current market rate as unrealized appreciation or depreciation. If securities are held at the end of the period, the changes in value are recorded in income as unrealized. Realized gains or losses are recognized when contracts are settled. Total return swap and credit default swap contracts are recorded at fair value as an asset or liability with changes in fair value recorded as unrealized appreciation or depreciation. Realized gains or losses are recognized at the termination of the contract based on the difference between the close-out price of the total return or credit default swap contract and the original contract price. Forward contracts are valued based on market rates obtained from counterparties or prices obtained from recognized financial data service providers.

INCOME TAXES

INCOME TAXES	9 Months Ended

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES The Company’s income tax (provision) benefit totaled $231.9 million and $(19.1) million for the three months ended September 30, 2019 and 2018 , respectively, and $195.3 million and $(46.6) million for the nine months ended September 30, 2019 and 2018 , respectively. The Company’s effective tax rate was approximately (80.2)% and 5.0% for the three months ended September 30, 2019 and 2018 , respectively, and (19.9)% and 10.5% for the nine months ended September 30, 2019 and 2018 , respectively. Under U.S. GAAP, a tax benefit from an uncertain tax position may be recognized when it is more likely than not that the position will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. Based upon the Company’s review of its federal, state, local and foreign income tax returns and tax filing positions, the Company determined that no unrecognized tax benefits for uncertain tax positions were required to be recorded, including any additional items related to the Conversion. In addition, the Company does not believe that it has any tax positions for which it is reasonably possible that it will be required to record significant amounts of unrecognized tax benefits within the next twelve months. The primary jurisdictions in which the Company operates are the United States, New York State, New York City, California and the United Kingdom. There are no unremitted earnings with respect to the United Kingdom and other foreign entities. In the normal course of business, the Company is subject to examination by federal and certain state, local and foreign tax authorities. With a few exceptions, as of September 30, 2019 , the Company’s U.S. federal, state, local and foreign income tax returns for the years 2015 through 2017 are open under the general statute of limitations provisions and therefore subject to examination. Currently, the Internal Revenue Service is examining the tax return of a subsidiary for the 2011 tax year. The State and City of New York are examining certain subsidiaries’ tax returns for tax years 2011 to 2013. Prior to the Conversion, Apollo and certain of its subsidiaries operated in the U.S. as partnerships for income tax purposes. Effective September 5, 2019, Apollo Global Management, Inc. converted from a Delaware limited liability company named Apollo Global Management, LLC to a Delaware corporation named Apollo Global Management, Inc. Subsequent to the Conversion, we expect that all of the income we earn will be subject to U.S. corporate income taxes, which could result in an overall higher income tax expense (or benefit) in periods subsequent to the Conversion. As of September 30, 2019 , the Company recorded a net deferred tax benefit of $207.5 million . The Company’s income tax provision and related income tax assets and liabilities are based on, among other things, an estimate of the impact of the Conversion. This includes the impact of the step-up in tax basis of certain assets related to prior exchanges of the Managing Partners’ and Contributing Partners’ AOG units for Class A Common Stock. Additionally, the estimate includes an analysis, as of September 5, 2019, of the difference between tax and book basis of certain partnerships and related underlying assets and liabilities previously not subject to corporate income taxes. The Company’s estimate of income tax assets and liabilities is based on the most recent information available; however, the impact of the Conversion cannot be fully determined until the analysis of the tax and book basis of underlying assets of certain partnerships not previously subject to corporate income taxes has been finalized. The Company does not expect such information and analysis to be available until 2020. The tax basis of the partnerships and their underlying assets and liabilities are based on estimates subject to finalization of the Company’s 2019 tax return information. As a result, the impact of the Conversion may differ, possibly materially, from the current estimates described herein. The Company recorded additional deferred tax assets as a result of the step-up in tax basis of intangibles from subsequent exchanges of AOG Units for Class A Common Stock. A related tax receivable agreement liability is recorded in due to related parties in the condensed consolidated statements of financial condition for the expected payments under the tax receivable agreement entered into by and among APO Corp., the Managing Partners, the Contributing Partners, and other parties thereto (as amended, the “tax receivable agreement”) (see note 14 ). The benefit the Company obtains from the difference in the tax asset recognized and the related liability results in an increase to additional paid in capital. The amortization period for a portion of these tax basis intangibles is 15 years and the remaining portion relates to the disposition of the underlying assets to which the step-up was attributable. The associated deferred tax assets will reverse over the same corresponding time periods. The table below presents the impact to the deferred tax asset, tax receivable agreement liability and additional paid in capital related to the exchange of AOG Units for Class A Common Stock. Exchange of AOG Units for Class A Common Stock Increase in Deferred Tax Asset Increase in Tax Receivable Agreement Liability Increase to Additional Paid In Capital For the Nine Months Ended September 30, 2019 $ 168,058 (1) $ 39,092 $ 16,658 For the Nine Months Ended September 30, 2018 $ 47,011 $ 39,605 $ 7,406 (1) For the nine months ended September 30, 2019, $150.9 million and $38.6 million of the increase in deferred tax asset and the increase in tax receivable agreement liability, respectively, shown above are related to the step-up in assets from AOG Unit exchanges in prior years triggered by the Conversion, and therefore do not increase additional paid in capital, but rather increase income tax benefit and decrease other income, respectively.

The 2013 AMH Credit Facilities provided for (i) a term loan facility to AMH (the “Term Facility”) that included $750 million of term loan from third-party lenders and $271.7 million of term loan held by a subsidiary of the Company and (ii) a $500 million revolving credit facility (the “Revolver Facility”), in each case, with an original maturity date of January 18, 2019. On March 11, 2016, the maturity date of both the Term Facility and the Revolver Facility was extended by two years to January 18, 2021. The extension was determined to be a modification of the 2013 AMH Credit Facilities in accordance with U.S. GAAP. In connection with the issuance of the 2024 Senior Notes, the 2026 Senior Notes and the 2048 Senior Notes (as described below), $250 million , $200 million and $300 million of the proceeds, respectively, were used to repay the entire remaining amount of both the term loan from third-party lenders and the term loan held by a subsidiary of the Company as of March 15, 2018. The Revolver Facility was replaced as of July 11, 2018 by the 2018 AMH Credit Facility, as described below.

The 2018 AMH Credit Facility provides for a $750 million revolving credit facility to the Borrower with a final maturity date of July 11, 2023. The 2018 AMH Credit Facility is to remain available until its maturity, and any undrawn revolving commitments bear a commitment fee. The interest rate on the 2018 AMH Credit Facility is based on adjusted LIBOR and the applicable margin as of September 30, 2019 was 1.00% . The commitment fee on the $750 million undrawn 2018 AMH Credit Facility as of September 30, 2019 was 0.09% .

(2) Participating securities consist of vested and unvested RSUs that have rights to dividends and unvested restricted shares. (3) No allocation of undistributed losses was made to the participating securities as the holders do not have a contractual obligation to share in the losses of the Company with Class A Common Stockholders. (4) For the three and nine months ended September 30, 2019 , unvested RSUs were determined to be dilutive, and were accordingly included in the diluted earnings per share calculation. For the three and nine months ended September 30, 2019 , the share options, AOG Units and participating securities were determined to be anti-dilutive and were accordingly excluded from the diluted earnings per share calculation. For the three and nine months ended September 30, 2018 , all of the classes of securities were determined to be anti-dilutive. The Company has granted RSUs that provide the right to receive, subject to vesting during continued employment, shares of Class A Common Stock pursuant to the Equity Plan. The Company has three types of RSU grants, which we refer to as Plan Grants, Bonus Grants and Performance Grants. “Plan Grants” vest over time (generally one to six years ) and may or may not provide the right to receive dividend equivalents on vested RSUs on an equal basis with the Class A Common Stockholders any time a dividend is declared. “Bonus Grants” vest over time (generally three years ) and generally provide the right to receive dividend equivalents on both vested and unvested RSUs on an equal basis with the Class A Common Stockholders any time a dividend is declared. “Performance Grants” generally vest over time ( three to five years ), subject to the Company’s receipt of performance revenues, within prescribed periods, sufficient to cover the associated equity-based compensation expense. Performance Grants provide the right to receive dividend equivalents on vested RSUs and may also provide the right to receive dividend equivalents on unvested RSUs. Any dividend equivalent paid to an employee will not be returned to the Company upon forfeiture of the award by the employee. Vested and unvested RSUs that are entitled to non-forfeitable dividend equivalents qualify as participating securities and are included in the Company’s basic and diluted earnings per share computations using the two-class method. The holder of an RSU participating security would have a contractual obligation to share in the losses of the entity if the holder is obligated to fund the losses of the issuing entity or if the contractual principal or mandatory redemption amount of the participating security is reduced as a result of losses incurred by the issuing entity. The RSU participating securities do not have a mandatory redemption amount and the holders of the participating securities are not obligated to fund losses, therefore, neither the vested RSUs nor the unvested RSUs are subject to any contractual obligation to share in losses of the Company. Holders of AOG Units are subject to the transfer restrictions set forth in the agreements with the respective holders and may, a limited number of times each year, upon notice (subject to the terms of an exchange agreement), exchange their AOG Units for shares of Class A Common Stock on a one -for- one basis. An AOG Unit holder must exchange one unit in each of the Apollo Operating Group partnerships or limited liability companies to effectuate an exchange for one share of Class A Common Stock. Apollo Global Management, Inc. has one share of Class B Common Stock outstanding, which is held by BRH Holdings GP, Ltd. (“BRH”). The voting power of the share of Class B Common Stock is reduced on a one vote per one AOG Unit basis in the event of an exchange of AOG Units for shares of Class A Common Stock, as discussed above. The Class B Common Stock has no net income (loss) per share as it does not participate in Apollo’s earnings (losses) or dividends. The Class B Common Stock has no dividend or liquidation rights. The Class B Common Stock represented 44.8% and 52.5% of the total voting power of the Company’s Class A Common Stock and Class B Common Stock with respect to the limited matters upon which they are entitled to vote pursuant to the Company’s governing documents as of September 30, 2019 and 2018 , respectively.

EQUITY-BASED COMPENSATION

EQUITY-BASED COMPENSATION	9 Months Ended
	Sep. 30, 2019
Share-based Payment Arrangement [Abstract]
EQUITY-BASED COMPENSATION	EQUITY-BASED COMPENSATION Equity-based awards granted to employees and non-employees as compensation are measured based on the grant date fair value of the award. Equity-based awards that do not require future service (i.e., vested awards) are expensed immediately. Equity-based employee awards that require future service are expensed over the relevant service period. Equity-based awards that require performance metrics to be met are expensed only when the performance metric is met or deemed probable. RSUs The Company grants RSUs under the Equity Plan. The fair value of all grants is based on the grant date fair value, which considers the public share price of the Company’s Class A Common Stock subject to certain discounts, as applicable. The estimated total grant date fair value for Plan Grants and Bonus Grants is charged to compensation expense on a straight-line basis over the vesting period, which for Plan Grants is generally one to six years , with the first installment vesting one year after grant and quarterly vesting thereafter, and for Bonus Grants is generally annual vesting over three years . During the nine months ended September 30, 2019 , the Company awarded Performance Grants of 1.3 million RSUs to certain employees with a grant date fair value of $27.6 million , which vest over time (generally 3 to 5 years ) subject to the receipt of performance revenues, within prescribed periods, sufficient to cover the associated equity-based compensation expense. Additionally, the Company modified Plan Grants of 0.5 million RSUs with a grant date fair value of $10.5 million to Performance Grants of 0.5 million RSUs. The modification did not result in a change to the grant date fair value of the awards, as performance conditions that impact vesting are not considered in the determination of the fair value of an award. In accordance with U.S. GAAP, equity-based compensation expense for these and other Performance Grants will be recognized on an accelerated recognition method over the requisite service period to the extent the performance revenue metrics are met or deemed probable. The following table summarizes the equity based compensation expense recognized relating to Performance Grants. For the Three Months Ended September 30, For the Nine Months Ended September 30, 2019 2018 2019 2018 Equity-based compensation 16,456 19,259 45,587 46,207 Additionally, the Company entered into an agreement in 2018 with several employees under which it expects to grant them RSUs beginning in 2020 if year-over-year growth in certain discretionary earnings metrics is attained prior to grant and they remain employed at the grant date. Once granted, these RSUs will vest based on both continued service and the Company’s receipt of performance revenues, within prescribed periods, sufficient to cover the associated equity-based compensation expense. In accordance with U.S. GAAP, equity-based compensation expense for such awards, if and when granted, will be recognized on an accelerated recognition method over the requisite service period to the extent the performance revenue metrics are met or deemed probable. No equity-based compensation expense was recognized related to these RSUs for the three and nine months ended September 30, 2019 . The fair value of all RSU grants made during the nine months ended September 30, 2019 and 2018 was $102.2 million and $227.1 million , respectively. The following table presents the actual forfeiture rates and equity-based compensation expense recognized: For the Three Months Ended September 30, For the Nine Months Ended September 30, 2019 2018 2019 2018 Actual forfeiture rate 0.5 % 0.7 % 1.7 % 8.0 % Equity-based compensation $ 33,771 $ 37,166 $ 101,709 $ 99,544 The following table summarizes RSU activity: Unvested Weighted Average Grant Date Fair Value Vested Total Number of RSUs Outstanding Balance at January 1, 2019 9,839,968 $ 26.52 2,380,783 12,220,751 (1) Granted 4,141,766 24.66 — 4,141,766 Forfeited (214,041 ) 26.01 (18,524 ) (232,565 ) Vested (2,001,237 ) 27.71 2,001,237 — Issued — 23.84 (4,146,944 ) (4,146,944 ) Balance at September 30, 2019 11,766,456 (2) $ 25.67 216,552 11,983,008 (1) (1) Amount excludes RSUs which have vested and have been issued in the form of Class A Common Stock. (2) RSUs were expected to vest over the weighted average period of 3.0 years. Restricted Share Awards—Athene Holding The Company has granted Athene Holding restricted share awards to certain employees of the Company. Separately, Athene Holding has also granted restricted share awards to certain employees of the Company. Both awards are collectively referred to as the “AHL Awards.” Certain of the AHL Awards function similarly to options as they are exchangeable for Class A shares of Athene Holding upon payment of a conversion price and the satisfaction of certain other conditions. The awards granted are either subject to time-based vesting conditions that generally vest over three to five years or vest upon achieving certain metrics, such as attainment of certain rates of return and realized cash received by certain investors in Athene Holding upon sale of their shares. The Company records the AHL Awards in other assets and other liabilities in the condensed consolidated statements of financial condition. The fair value of the asset is amortized through equity-based compensation over the vesting period. The fair value of the liability is remeasured each period, with any changes in fair value recorded in compensation expense in the condensed consolidated statements of operations. For AHL Awards granted by Athene Holding, compensation expense related to amortization of the asset is offset, with certain exceptions, by related management fees earned by the Company from Athene. The grant date fair value of the AHL Awards is based on the share price of Athene Holding, less discounts for transfer restrictions, and has been categorized as Level II within the fair value hierarchy as a result. The AHL Awards that function similarly to options were valued using a multiple-scenario model, which considers the price volatility of the underlying share price of Athene Holding, time to expiration and the risk-free rate, while the other awards were valued using the share price of Athene Holding less any discounts for transfer restrictions. The following table summarizes the management fees, equity-based compensation expense and actual forfeiture rates for the AHL Awards: For the Three Months Ended September 30, For the Nine Months Ended September 30, 2019 2018 2019 2018 Management fees $ (167 ) $ 1,872 $ 375 $ (14 ) Equity-based compensation 194 3,349 1,909 1,075 Actual forfeiture rate — % — % — % 3.6 % Equity-Based Compensation Allocation Equity-based compensation is allocated based on ownership interests. Therefore, the amortization of equity-based compensation is allocated to stockholders’ equity attributable to AGM Inc. and the Non-Controlling Interests, which results in a difference in the amounts charged to equity-based compensation expense and the amounts credited to stockholders’ equity attributable to AGM in the Company’s condensed consolidated financial statements. Below is a reconciliation of the equity-based compensation allocated to AGM Inc.: For the Nine Months Ended September 30, 2019 Total Amount Non-Controlling Interest % in Apollo Operating Group Allocated to Non-Controlling Interest in Apollo Operating Group (1) Allocated to Apollo Global Management, Inc.

Equity [Abstract]
EQUITY	EQUITY Common Stock As a result of the Conversion, (i) each Class A Share converted into one share of Class A Common Stock (ii) the Class B Share converted into one share of Class B Common Stock and (iii) the Former Manager was granted one issued and outstanding, fully paid and nonassessable share of Class C Common Stock, which bestows to its holder certain management rights over the Company. Holders of Class A Common Stock are entitled to participate in dividends from the Company on a pro rata basis. Holders of Class A Common Stock do not elect the members of the Company’s board of directors and have limited voting rights. During the three and nine months ended September 30, 2019 and 2018 , the Company issued shares of Class A Common Stock in settlement of vested RSUs. The Company has generally allowed holders of vested RSUs and exercised share options to settle their tax liabilities by reducing the number of shares of Class A Common Stock issued to them, which the Company refers to as “net share settlement.” Additionally, the Company has generally allowed holders of share options to settle their exercise price by reducing the number of shares of Class A Common Stock issued to them at the time of exercise by an amount sufficient to cover the exercise price. The net share settlement results in a liability for the Company and a corresponding accumulated deficit adjustment. In February 2016, Apollo announced its adoption of a program to repurchase up to $250 million in the aggregate of its shares of Class A Common Stock, including up to $150 million in the aggregate of its outstanding shares of Class A Common Stock through a share repurchase program and up to $100 million through net share settlement of equity-based awards granted under the Equity Plan. In January 2019, Apollo increased its authorized share repurchase amount by $250 million bringing the total authorized repurchase amount to $500 million , which may be used to repurchase outstanding shares of Class A Common Stock as well as to reduce the number of shares of Class A Common Stock to be issued to employees to satisfy associated tax obligations in connection with the settlement of equity-based awards granted under the the Equity Plan (or any successor equity plan thereto). Shares of Class A Common Stock may be repurchased from time to time in open market transactions, in privately negotiated transactions, pursuant to a trading plan adopted in accordance with Rule 10b5-1 of the Exchange Act, or otherwise, with the size and timing of these repurchases depending on legal requirements, price, market and economic conditions and other factors. Apollo is not obligated under the terms of the program to repurchase any of its shares of Class A Common Stock. The repurchase program has no expiration date and may be suspended or terminated by the Company at any time without prior notice. The table below summarizes the issuance of shares of Class A Common Stock for equity-based awards: For the Nine Months Ended September 30, 2019 2018 Shares of Class A Common Stock issued in settlement of vested RSUs and share options exercised (1) 4,146,944 3,587,931 Reduction of shares of Class A Common Stock issued (2) (1,585,734 ) (1,201,328 ) Shares of Class A Common Stock purchased related to share issuances and forfeitures (3) (103,954 ) (183,969 ) Issuance of shares of Class A Common Stock for equity-based awards 2,457,256 2,202,634 (1) The gross value of shares issued was $127.2 million and $120.6 million for the nine months ended September 30, 2019 and 2018 , respectively, based on the closing price of a share of Class A Common Stock at the time of issuance. (2) Cash paid for tax liabilities associated with net share settlement was $48.8 million and $40.3 million for the nine months ended September 30, 2019 and 2018 , respectively. (3) Certain Apollo employees receive a portion of the profit sharing proceeds of certain funds in the form of (a) restricted shares of Class A Common Stock of AGM Inc. that they are required to purchase with such proceeds or (b) RSUs, in each case which equity-based awards generally vest over three years . These equity-based awards are granted under the Company's Equity Plan. To prevent dilution on account of these awards, Apollo may, in its discretion, repurchase of shares of Class A Common Stock on the open market and retire them.

Dividends on the Preferred Stock are discretionary and non-cumulative. During 2019, quarterly cash dividends were $0.398438 per share of Series A Preferred Stock and Series B Preferred Stock. Subject to certain exceptions, unless dividends have been declared and paid or declared and set apart for payment on the Preferred Stock for a quarterly dividend period, during the remainder of that dividend period Apollo may not declare or pay or set apart payment for dividends on any shares of Class A Common Stock or any other equity securities that the Company may issue in the future ranking as to the payment of dividends, junior to the Preferred Stock (“Junior Stock”) and Apollo may not repurchase any Junior Stock. These restrictions were not applicable during the initial dividend period, which was the period from March 19, 2018 to but excluding June 15, 2018 for the Series B Preferred Stock. The Series A Preferred Stock and the Series B Preferred Stock may be redeemed at Apollo’s option, in whole or in part, at any time on or after March 15, 2022 and March 15, 2023, respectively, at a price of $25.00 per share of Preferred Stock, plus declared and unpaid dividends to, but excluding, the redemption date, without payment of any undeclared dividends. Holders of the Preferred Stock will have no right to require the redemption of the Preferred Stock and there is no maturity date. If a certain change of control event or a certain tax redemption event occurs prior to March 15, 2022 and March 15, 2023 for the Series A Preferred Stock and the Series B Preferred Stock, respectively, the Preferred Stock may be redeemed at Apollo’s option, in whole but not in part, upon at least 30 days’ notice, within 60 days of the occurrence of such change of control event or such tax redemption event, as applicable, at a price of $25.25 per share of Preferred Stock, plus declared and unpaid dividends to, but excluding, the redemption date, without payment of any undeclared dividends.

In connection with the issuance of the Preferred Stock, certain Apollo Operating Group entities issued for the benefit of Apollo a series of preferred units with economic terms that mirror those of the Preferred Stock. Dividends and Distributions The table below presents information regarding the quarterly dividends and distributions which were made at the sole discretion of the Former Manager of the Company prior to the Conversion (in millions, except per share data). Certain subsidiaries of AGM Inc. may be subject to U.S. federal, state, local and non-U.S. income taxes at the entity level and may pay taxes and/or make payments under the tax receivable agreement in a given fiscal year; therefore, the net amounts ultimately distributed by AGM Inc. to its Class A Common Stockholders in respect of each fiscal year are generally expected to be less than the net amounts distributed to AOG Unitholders. Subsequent to the Conversion, distributions from AGM Inc. are referred to as dividends.

RELATED PARTY TRANSACTIONS AND INTERESTS IN CONSOLIDATED ENTITIES	RELATED PARTY TRANSACTIONS AND INTERESTS IN CONSOLIDATED ENTITIES Management fees, transaction and advisory fees and reimbursable expenses from the funds the Company manages and their portfolio companies are included in due from related parties in the condensed consolidated statements of financial condition. The Company also typically facilitates the payment of certain operating costs incurred by the funds that it manages as well as their related parties. These costs are normally reimbursed by such funds and are included in due from related parties. Other related party transactions include loans to employees and periodic sales of ownership interests in Apollo funds to employees. Due from related parties and due to related parties are comprised of the following: As of As of Due from Related Parties: Due from credit funds $ 190,919 $ 153,687 Due from private equity funds 21,901 19,993 Due from real assets funds 34,307 42,471 Due from portfolio companies 57,783 67,740 Due from Contributing Partners, employees and former employees 135,161 94,217 Total Due from Related Parties $ 440,071 $ 378,108 Due to Related Parties: Due to Managing Partners and Contributing Partners $ 287,456 $ 285,598 Due to credit funds 4,212 3,444 Due to private equity funds 215,110 136,078 Due to real assets funds 335 315 Total Due to Related Parties $ 507,113 $ 425,435 Tax Receivable Agreement Subject to certain restrictions, each of the Managing Partners and Contributing Partners has the right to exchange his vested AOG Units for the Company’s Class A Common Stock. All Operating Group entities have made, or will make, an election under Section 754 of the U.S. Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), which will result in an adjustment to the tax basis of the assets owned by the Apollo Operating Group at the time of the exchange. These exchanges will result in increases in the basis of underlying assets that will reduce the amount of tax that AGM Inc. and its subsidiaries will otherwise be required to pay in the future. The tax receivable agreement provides for the payment to the Managing Partners and Contributing Partners of 85% of the amount of cash savings, if any, in U.S. federal, state, local and foreign income taxes that AGM Inc. and its subsidiaries would realize as a result of the increases in tax basis of assets that resulted from the 2007 Reorganization, the Conversion and exchanges of AOG Units for Class A Common Stock. AGM Inc. and its subsidiaries retains the benefit from the remaining 15% of actual cash tax savings. If the Company does not make the required annual payment on a timely basis as outlined in the tax receivable agreement, interest is accrued on the balance until the payment date. As a result of the exchanges of AOG Units for Class A Common Stock during the nine months ended September 30, 2019 and 2018 , a $39.1 million and $39.6 million liability was recorded, respectively, to estimate the amount of the future expected payments to be made by AGM Inc. and its subsidiaries to the Managing Partners and Contributing Partners pursuant to the tax receivable agreement. In April 2019, Apollo made a $37.2 million cash payment pursuant to the tax receivable agreement resulting from the realized tax benefit for the 2018 tax year. Additionally, in connection with this payment, the Company made a corresponding pro rata distribution of $37.4 million ( $0.18 per AOG Unit) to the Non-Controlling Interest holders in the Apollo Operating Group. In April 2018, Apollo made a $50.3 million cash payment pursuant to the tax receivable agreement resulting from the realized tax benefit for the 2017 tax year. Additionally, in connection with this payment, the Company made a corresponding pro rata distribution of $50.5 million ( $0.25 per AOG Unit) to the Non-Controlling Interest holders in the Apollo Operating Group. Due from Contributing Partners, Employees and Former Employees As of September 30, 2019 and December 31, 2018 , due from Contributing Partners, Employees and Former Employees includes various amounts due to the Company including employee loans and return of profit sharing distributions. As of September 30, 2019 and December 31, 2018 , the balance included interest-bearing employee loans receivable of $17.0 million and $16.8 million , respectively. The outstanding principal amount of the loans as well as all accrued and unpaid interest is required to be repaid at the earlier of the eighth anniversary of the date of the relevant loan or at the date of the relevant employee’s resignation from the Company. The Company recorded a receivable from the Contributing Partners and certain employees and former employees for the potential return of profit sharing distributions that would be due if certain funds were liquidated as of September 30, 2019 and December 31, 2018 of $103.3 million and $66.3 million , respectively. Indemnity Performance revenues from certain funds can be distributed to the Company on a current basis, but are subject to repayment by the subsidiaries of the Apollo Operating Group that act as general partners of the funds in the event that certain specified return thresholds are not ultimately achieved. The Managing Partners, Contributing Partners and certain other investment professionals have personally guaranteed, subject to certain limitations, the obligations of these subsidiaries in respect of this general partner obligation. Such guarantees are several and not joint and are limited to a particular Managing Partner’s or Contributing Partner’s distributions. Pursuant to an existing shareholders agreement, the Company has agreed to indemnify each of the Company’s Managing Partners and certain Contributing Partners against all amounts that they pay pursuant to any of these personal guarantees in favor of certain funds that the Company manages (including costs and expenses related to investigating the basis for or objecting to any claims made in respect of the guarantees) for all interests that the Company’s Managing Partners and Contributing Partners have contributed or sold to the Apollo Operating Group. Accordingly, in the event that the Company’s Managing Partners, Contributing Partners and certain investment professionals are required to pay amounts in connection with a general partner obligation for the return of previously made distributions with respect to Fund IV, Fund V and Fund VI, the Company will be obligated to reimburse the Company’s Managing Partners and certain Contributing Partners for the indemnifiable percentage of amounts that they are required to pay even though the Company did not receive the certain distribution to which that general partner obligation related. The Company recorded an indemnification liability of $12.7 million and $12.2 million as of September 30, 2019 and December 31, 2018 , respectively. Due to Credit, Private Equity and Real Assets Funds Based upon an assumed liquidation of certain of the credit, private equity and real assets funds the Company manages, the Company has recorded a general partner obligation to return previously distributed performance allocations, which represents amounts due to these funds. The general partner obligation is recognized based upon an assumed liquidation of a fund’s net assets as of the reporting date. The actual determination and any required payment of any such general partner obligation would not take place until the final disposition of a fund’s investments based on the contractual termination of the fund or as otherwise set forth in the respective limited partnership agreement or other governing document of the fund. The following table presents the general partner obligation to return previously distributed performance allocations related to certain funds by segment: As of As of Credit $ 320 $ 1,370 Private Equity 213,573 135,723 Total general partner obligation $ 213,893 $ 137,093 Athene Athene Holding was founded in 2009 to capitalize on favorable market conditions in the dislocated life insurance sector.

Litigation and Contingencies— Apollo is, from time to time, party to various legal actions arising in the ordinary course of business including claims and lawsuits, reviews, investigations or proceedings by governmental and self-regulatory agencies regarding its business. On June 20, 2016 Banca Carige S.p.A. (“Carige”) commenced a lawsuit in the Court of Genoa (Italy) (No. 8965/2016), against its former Chairman, its former Chief Executive Officer, AGM Inc. and certain entities (the “Apollo Entities”) organized and owned by investment funds managed by affiliates of AGM Inc. The complaint alleged that AGM Inc. and the Apollo Entities (i) aided and abetted breaches of fiduciary duty to Carige allegedly committed by Carige’s former Chairman and former CEO in connection with the sale to the Apollo Entities of Carige subsidiaries engaged in the insurance business; and (ii) took wrongful actions aimed at weakening Banca Carige’s financial condition supposedly to facilitate an eventual acquisition of Carige. The causes of action were based in tort under Italian law. Carige purportedly seeks damages of €450 million in connection with the sale of the insurance businesses and €800 million for other losses. With judgment no. 3118/2018 published on December 6, 2018, the Court of Genoa fully rejected all the claims raised by Carige against AGM Inc. and the Apollo Entities, also awarding attorneys' fees in their favor for an amount of €428,996.10 . Carige filed an appeal on January 3, 2019 before the Court of Appeal of Genoa. The Apollo Entities appeared in the proceedings requesting the Court to reject Banca Carige’s appeal. By decree dated August 12, 2019, the Court of Appeal rejected some preliminary requests made by the former directors, including their request to join insurance companies and other members of the board of directors of Carige in the proceedings. By the same decree, the Court of Appeal scheduled the next hearing on September 22, 2021. Although the case appears to be in its final stages, no reasonable estimate of possible loss, if any, can be made at this time. On December 12, 2016, the CORE Litigation Trust (the “Trust”), which was created under the Chapter 11 reorganization plan for CORE Media and other affiliated entities, including CORE Entertainment, Inc. (“CORE”), commenced an action in California Superior Court for Los Angeles County, captioned Core Litigation Trust v. Apollo Global Management, LLC, et al., Case No. BC 643732, that was stayed on October 3, 2017, in favor of litigating in New York state court. On November 9, 2017, the Trust commenced an action in the Supreme Court of the State of New York, captioned Core Litigation Trust v. Apollo Global Management, LLC, et al., Index No. 656856/2017. The complaint names as defendants: (i) AGM Inc. and certain AGM Inc. affiliates including the Apollo-managed funds that were CORE’s beneficial owners (the “CORE Funds”), (ii) Twenty-First Century Fox, Inc. (“Fox”) and certain Fox affiliates, (iii) Endemol USA Holding, Inc. (“Endemol”) and certain Endemol-affiliated entities, and (iv) the joint venture through which the CORE Funds and Fox beneficially owned CORE Media and Endemol Shine (the “JV”). The Trust asserts claims against (i) all defendants for tortiously interfering with $360 million in loans under the 2011 loan agreements entered into between CORE and certain Lenders, and (ii) certain defendants for alter-ego and de-facto merger. The Trust seeks $240 million in compensatory, unspecified punitive damages, pre-judgment interests, and costs and expenses. Under the parties’ agreement, dated as of August 19, 2019, to settle and release all of the Trust’s claims against Defendants, both the New York and California actions have been dismissed with prejudice. On August 3, 2017, a complaint was filed in the United States District Court for the Middle District of Florida against AGM Inc., a senior partner of Apollo and a former principal of Apollo by Michael McEvoy on behalf of a purported class of employees of subsidiaries of CEVA Group, LLC (“CEVA Group”) who purchased shares in CEVA Investment Limited (“CIL”), the former parent company of CEVA Group. The complaint alleged that the defendants breached fiduciary duties to and defrauded the plaintiffs by inducing them to purchase shares in CIL and subsequently participating in a debt restructuring of CEVA Group in which shareholders of CIL did not receive a recovery. On February 9, 2018, the Bankruptcy Court for the Southern District of New York held that the claims asserted in the complaint were assets of CIL, which is a chapter 7 debtor, and that the complaint was null and void as a violation of the automatic stay. McEvoy subsequently revised his complaint to attempt to assert claims that do not belong to CIL. The amended complaint no longer names any individual defendants, but Apollo Management VI, L.P. and CEVA Group have been added as defendants. The amended complaint purports to seek damages of approximately €30 million and asserts, among other things, claims for violations of the Investment Advisers Act of 1940, breach of fiduciary duties, and breach of contract. On December 7, 2018, after receiving permission from the Bankruptcy Court, McEvoy filed his amended complaint in the District Court in Florida. Apollo is currently seeking dismissal of this action and believes that there is no merit to the claims. On October 28, 2019, the District Court in Florida scheduled a hearing for December 3, 2019 on Apollo and CEVA Group’s motions to dismiss. As the case is in its early stages, no reasonable estimate of possible loss, if any, can be made at this time. On December 21, 2017, Harbinger Capital Partners II, LP, Harbinger Capital Partners Master Fund I, Ltd., Harbinger Capital Partners Special Situations Fund, L.P., Harbinger Capital Partners Special Situations GP, LLC, Harbinger Capital Partners Offshore Manager, L.L.C., Global Opportunities Breakaway Ltd. (in voluntary liquidation), and Credit Distressed Blue Line Master Fund, Ltd. (collectively, “Harbinger”) commenced an action in New York Supreme Court captioned Harbinger Capital Partners II LP et al. v. Apollo Global Management LLC, et al. (No. 657515/2017). The complaint names as defendants (i) AGM Inc., (ii) the funds managed by Apollo that invested in SkyTerra Communications, Inc. (“SkyTerra”) equity before selling their interests to Harbinger under an April 2008 agreement that closed in 2010, and (iii) six former SkyTerra directors, five of whom are current or former Apollo employees. The complaint alleges that during the period of Harbinger’s various equity and debt investments in SkyTerra, from 2004 to 2010, the defendants concealed from Harbinger material defects in SkyTerra technology that was to be used to create a new mobile wi-fi network. The complaint alleges that Harbinger would not have made investments in SkyTerra totaling approximately $1.9 billion had it known of the defects, and that the public disclosure of these defects ultimately led to SkyTerra filing for bankruptcy in 2012 (after it had been renamed LightSquared). The complaint asserts claims against (i) all defendants for fraud, civil conspiracy, and negligent misrepresentation, (ii) AGM Inc. and the Apollo-managed funds only for breach of fiduciary duty, breach of contract, and unjust enrichment, and (iii) the SkyTerra director defendants only for aiding and abetting breach of fiduciary duty. The complaint seeks $1.9 billion in damages, as well as punitive damages, interest, costs, and fees. This action was stayed from February 14, 2018, through June 12, 2019. On February 14, 2018, the defendants moved the United States Bankruptcy Court for the Southern District of New York to reopen the LightSquared bankruptcy proceeding for the limited purpose of enforcing Harbinger’s assignment and release in that bankruptcy of the claims that it asserts in the New York state court action. Briefing and hearing on this motion were adjourned while the state court stay was pending. On June 12, 2019, Harbinger voluntarily discontinued the state action without prejudice subject to a tolling agreement. On June 12, 2019, Apollo voluntarily withdrew its bankruptcy court motion subject to a right to refile the motion if Harbinger were to refile the state court action. Apollo believes these claims are without merit. Because this action is in its early stages, no reasonable estimate of possible loss, if any, can be made at this time. Five shareholders filed substantially similar putative class action lawsuits in the Circuit Court of the Fifteenth Judicial Circuit in and for Palm Beach County, Florida in March, April, and May 2018, alleging violations of the Securities Act in connection with the January 19, 2018 IPO of ADT Inc. common stock. The actions were consolidated on July 10, 2018, and the case was re-captioned In re ADT Inc. Shareholder Litigation. On August 24, 2018, the state-court plaintiffs filed a consolidated complaint naming as defendants ADT Inc., several ADT officers and directors, the IPO underwriters (including Apollo Global Securities, LLC), AGM Inc. and certain other Apollo affiliates. Plaintiffs generally allege that the registration statement and prospectus for the IPO contained false and misleading statements and failed to disclose material information about certain litigation in which ADT was involved, ADT’s efforts to protect its intellectual property, and competitive pressures ADT faced. Defendants filed motions to dismiss the consolidated complaint on October 23, 2018, and those motions are fully briefed. On May 21, 2018, a similar shareholder class action lawsuit was filed in the United States District Court for the Southern District of Florida, naming as defendants ADT, several officers and directors, and AGM Inc. The federal action, captioned Perdomo v. ADT Inc., generally alleges that the registration statement was materially misleading because it failed to disclose ongoing deterioration in ADT’s financial results, along with certain customer and business metrics. On July 20, 2018, several alleged ADT shareholders filed competing motions to be named lead plaintiff in the federal action. On November 20, 2018, the court appointed a lead plaintiff, and on January 15, 2019, the lead plaintiff filed an amended complaint. The amended complaint names the same Apollo-affiliated defendants as the state-court action, along with three new Apollo entities. Defendants filed motions to dismiss on March 25, 2019, and those motions are fully briefed. On July 26, 2019, the state court denied defendants’ motions to dismiss, except it reserved judgment on the question whether it has personal jurisdiction over certain defendants, including the Apollo defendants. On September 12, 2019, all parties to the state and federal actions reached a settlement in principle of both actions, subject to court approval. The settlement requires no payment from any Apollo defendants. On May 3, 2018, Caldera Holdings Ltd, Caldera Life Reinsurance Company, and Caldera Shareholder, L.P. (collectively, “Caldera”) filed a summons with notice in the Supreme Court of the State of New York, New York County, naming as defendants AGM Inc., Apollo Management, L.P., Apollo Advisors VIII, L.P., Apollo Capital Management VIII, LLC, Athene Asset Management, L.P., Athene Holding, Ltd., and Leon Black (collectively, “Defendants” and all but Athene Holding, Ltd., the “Apollo Defendants”). On July 12, 2018, Caldera filed a complaint, Index No. 652175/2018 (the “Complaint”), alleging three causes of action: (1) tortious interference with prospective business relations/prospective economic advantage; (2) defamation/trade disparagement/injurious falsehood; and (3) unfair competition. The Complaint seeks damages of no less than $1.5 billion , as well as exemplary and punitive damages, attorneys’ fees, interest, and an injunction. Defendants moved to dismiss the Complaint on September 21, 2018 and Caldera filed an amended complaint on January 21, 2019 (the “Amended Complaint”). Defendants have moved to dismiss the Amended Complaint, and the Apollo Defendants have submitted to the Court a Final Arbitration Award issued on April 26, 2019 in a JAMS arbitration, finding Caldera, Imran Siddiqui, and Ming Dang liable for various causes of action, including breaches of fiduciary duty and/or aiding and abetting thereof. Oral argument on the motions to dismiss was held on May 31, 2019. The Apollo Defendants believe that the claims contained in the Complaint lack merit and intend to defend the case vigorously. Because this action is in the early stages, no reasonable estimate of possible loss, if any, can be made at this time. On March 7, 2019, plaintiff Elizabeth Morrison filed an amended complaint in an action captioned Morrison v. Ray Berry, et. al., Case No. 12808-VCG, pending in the Chancery Court for the State of Delaware, adding as defendants AGM Inc. and certain AGM Inc. affiliates. The original complaint had only named as defendants certain officers and directors (the “TFM defendants”) of The Fresh Market, Inc. (“TFM”), claiming that those defendants breached their fiduciary duties to the TFM shareholders in connection with their consideration and approval of a merger agreement between TFM and certain entities affiliated with Apollo, including by engaging in a sale process that improperly favored AGM Inc., and/or Apollo Management VIII, L.P., by agreeing to an inadequate price and by filing materially deficient disclosures regarding the transaction. In addition to AGM Inc., the amended complaint added as defendants Apollo Overseas Partners (Delaware 892) VIII, L.P., Apollo Overseas Partners (Delaware) VIII, L.P., Apollo Overseas Partners VIII, L.P., Apollo Management VIII, L.P., AIF VIII Management, LLC, Apollo Management, L.P., Apollo Management GP, LLC, Apollo Management Holdings, L.P., Apollo Management Holdings GP, LLC, APO Corp., AP Professional Holdings, L.P., Apollo Advisors VIII, L.P., Apollo Investment Fund VIII, L.P., and Pomegranate Holdings, Inc., and other defendants. The amended complaint alleges that the Apollo defendants aided and abetted the breaches of fiduciary duties by the TFM defendants. After the defendants moved to dismiss the complaint on May 1, 2019, Plaintiff filed a second amended complaint on June 3, 2019, maintaining the same claim against the same Apollo defendants as the prior complaint. Defendants moved to dismiss the second amended complaint on July 12, 2019. The court heard oral argument on the motions on September 23, 2019, and took them under advisement. Apollo believes the claims in this action are without merit. Because this action is in the early stages, no reasonable estimate of possible loss, if any, can be made at this time. Commitments and Contingencies— Other long-term obligations relate to payments with respect to certain consulting agreements entered into by Apollo Investment Consulting LLC, a subsidiary of Apollo, as well as long-term service contracts. A significant portion of these costs are reimbursable by funds or portfolio companies. As of September 30, 2019 , fixed and determinable payments due in connection with these obligations were as follows: Remaining 2019 2020 2021 2022 2023 Thereafter Total Other long-term obligations $ 8,884 $ 8,435 $ 1,836 $ 881 $ 654 $ 654 $ 21,344 Contingent Obligations— Performance allocations with respect to certain funds are subject to reversal in the event of future losses to the extent of the cumulative revenues recognized in income to date. If all of the existing investments became worthless, the amount of cumulative revenues that have been recognized by Apollo through September 30, 2019 and that would be reversed approximates $2.3 billion . Management views the possibility of all of the investments becoming worthless as remote. Performance allocations are affected by changes in the fair values of the underlying investments in the funds that Apollo manages. Valuations, on an unrealized basis, can be significantly affected by a variety of external factors including, but not limited to, bond yields and industry trading multiples. Movements in these items can affect valuations quarter to quarter even if the underlying business fundamentals remain stable. Additionally, at the end of the life of certain funds that the Company manages, there could be a payment due to a fund by the Company if the Company, as general partner, has received more performance allocations than was ultimately earned. The general partner obligation amount, if any, will depend on final realized values of investments at the end of the life of each fund or as otherwise set forth in the respective limited partnership agreement of the fund. See note 14 to our condensed consolidated financial statements for further details regarding the general partner obligation. Certain funds may not generate performance allocations as a result of unrealized and realized losses that are recognized in the current and prior reporting period. In certain cases, performance allocations will not be generated until additional unrealized and realized gains occur. Any appreciation would first cover the deductions for invested capital, unreturned organizational expenses, operating expenses, management fees and priority returns based on the terms of the respective fund agreements. One of the Company’s subsidiaries, AGS, provides underwriting commitments in connection with securities offerings to the portfolio companies of the funds Apollo manages. As of September 30, 2019 , there were no underwriting commitments. Contingent Consideration— In connection with the acquisition of Stone Tower in April 2012, the Company agreed to pay the former owners of Stone Tower a specified percentage of any future performance revenues earned from certain of the Stone Tower funds, CLOs, and strategic investment accounts. This contingent consideration liability was determined based on the present value of estimated future performance revenue payments, and is recorded in profit sharing payable in the condensed consolidated statements of financial condition. The fair value of the remaining contingent obligation was $96.4 million and $74.5 million as of September 30, 2019 and December 31, 2018 , respectively. The contingent consideration obligations will be remeasured to fair value at each reporting period until the obligations are satisfied and are characterized as Level III liabilities. The changes in the fair value of the contingent consideration obligations is reflected in profit sharing expense in the condensed consolidated statements of operations. See note 6 for further information regarding fair value measurements.

SEGMENT REPORTING

SEGMENT REPORTING	9 Months Ended

Segment Reporting [Abstract]
SEGMENT REPORTING	SEGMENT REPORTING Apollo conducts its business primarily in the United States and substantially all of its revenues are generated domestically. Apollo’s business is conducted through three reportable segments: credit, private equity and real assets. Segment information is utilized by our Managing Partners, who operate collectively as our chief operating decision maker, to assess performance and to allocate resources. These segments were established based on the nature of investment activities in each underlying fund, including the specific type of investment made and the level of control over the investment. The performance is measured by the Company’s chief operating decision maker on an unconsolidated basis because management makes operating decisions and assesses the performance of each of Apollo’s business segments based on financial and operating metrics and data that exclude the effects of consolidation of any of the affiliated funds. Segment Reporting Changes During the first quarter of 2019, Apollo’s chief operating decision maker determined that Segment Distributable Earnings, together with its main components including Fee Related Earnings, is the key performance measure used by management in evaluating the performance of Apollo’s credit, private equity and real assets segments. Accordingly, Apollo will no longer report Economic Income. Apollo believes these changes better reflect the manner in which it makes key operating decisions pertaining to resource allocation, capital deployment, budgeting and forecasting, and are consistent with what stockholders consider to be most important in evaluating its performance. Apollo determined to change the business segment in which it reports certain funds and accounts to align its segment reporting with the manner in which such funds and accounts were managed. Effective January 1, 2019, the European Principal Finance Fund series, which has been historically reported in the credit segment, moved to the real assets segment. Several funds and accounts that generally invest in illiquid opportunistic investments and the latest fund in the Credit Opportunity Fund series, which have been historically reported in the credit segment, moved to the private equity segment. Certain commercial real estate mortgage loan assets, previously reported in the credit segment, moved to the real assets segment. These changes affected the composition, but not the determination, of Apollo’s reporting segments. Apollo changed its definition of “Distributable Earnings” to include depreciation and amortization expenses and renamed it “Segment Distributable Earnings.” Historically, depreciation and amortization expenses were not reflected in Apollo’s calculation of Segment Distributable Earnings. Apollo also renamed “Distributable Earnings after Taxes and Related Payables” to “Distributable Earnings.” In connection with these changes, all prior periods have been recast to conform to the new presentation. Consequently, this information will be different from the historical segment financial results previously reported by Apollo in its reports filed with the SEC. Segment Distributable Earnings Segment Distributable Earnings, or “Segment DE”, is the key performance measure used by management in evaluating the performance of Apollo’s credit, private equity and real assets segments. Management believes the components of Segment DE, such as the amount of management fees, advisory and transaction fees and realized performance fees, are indicative of the Company’s performance. Management uses Segment DE in making key operating decisions such as the following: • Decisions related to the allocation of resources such as staffing decisions including hiring and locations for deployment of the new hires; • Decisions related to capital deployment such as providing capital to facilitate growth for the business and/or to facilitate expansion into new businesses; • Decisions related to expenses, such as determining annual discretionary bonuses and equity-based compensation awards to its employees. With respect to compensation, management seeks to align the interests of certain professionals and selected other individuals with those of the investors in the funds and those of Apollo’s stockholders by providing such individuals a profit sharing interest in the performance fees earned in relation to the funds. To achieve that objective, a certain amount of compensation is based on Apollo’s performance and growth for the year; and • Decisions related to the amount of earnings available for dividends to Class A Common Stockholders, holders of RSUs that participate in dividends and holders of AOG Units. Segment DE is a measure of profitability and has certain limitations in that it does not take into account certain items included under U.S. GAAP. Segment DE represents the amount of Apollo’s net realized earnings, excluding the effects of the consolidation of any of the related funds, Taxes and Related Payables, transaction-related charges and any acquisitions. Transaction-related charges includes equity-based compensation charges, the amortization of intangible assets, contingent consideration and certain other charges associated with acquisitions. In addition, Segment DE excludes non-cash revenue and expense related to equity awards granted by unconsolidated related parties to employees of the Company, compensation and administrative related expense reimbursements, as well as the assets, liabilities and operating results of the funds and variable interest entities that are included in the condensed consolidated financial statements. We believe the exclusion of the non-cash charges related to the 2007 Reorganization for equity-based compensation provides investors with a meaningful indication of our performance because these charges relate to the equity portion of our capital structure and not our core operating performance. Segment DE also excludes impacts of the remeasurement of the tax receivable agreement recorded in other income, which arises from changes in the associated deferred tax balance. Segment DE may not be comparable to similarly titled measures used by other companies and is not a measure of performance calculated in accordance with U.S. GAAP. We use Segment DE as a measure of operating performance, not as a measure of liquidity. Segment DE should not be considered in isolation or as a substitute for net income or other income data prepared in accordance with U.S. GAAP. The use of Segment DE without consideration of related U.S. GAAP measures is not adequate due to the adjustments described above. Management compensates for these limitations by using Segment DE as a supplemental measure to U.S. GAAP results, to provide a more complete understanding of our performance as management measures it. A reconciliation of Segment DE to its most directly comparable U.S. GAAP measure of income (loss) before income tax provision can be found in this footnote. Fee Related Earnings Fee Related Earnings (“FRE”) is derived from our segment reported results and refers to a component of Segment DE that is used as a supplemental performance measure to assess whether revenues that we believe are generally more stable and predictable in nature, primarily consisting of management fees, are sufficient to cover associated operating expenses and generate profits. FRE is the sum across all segments of (i) management fees, (ii) advisory and transaction fees, (iii) performance fees earned from business development companies and Redding Ridge Holdings (as defined below) and (iv) other income, net, less (x) salary, bonus and benefits, excluding equity-based compensation, (y) other associated operating expenses and (z) non-controlling interests in the management companies of certain funds the Company manages.

Subsequent Events [Abstract]
SUBSEQUENT EVENTS	SUBSEQUENT EVENTS On October 27, 2019 Athene Holding Ltd., a Bermuda exempted company (“AHL”), AGM and the entities that form the Apollo Operating Group entered into a Transaction Agreement (the “Transaction Agreement”), pursuant to which, among other things: • (i) AHL will issue 27,959,184 Class A common shares of AHL (the “AHL Class A Common Shares”) to certain subsidiaries of the Apollo Operating Group in exchange for an issuance by the Apollo Operating Group of 29,154,519 non-voting equity interests of the Apollo Operating Group to AHL and (ii) AGM, through the Apollo Operating Group, will purchase an additional $350 million of AHL Class A Common Shares (the “Share Issuance”); • AHL has granted to AGM the right to purchase additional AHL Class A Common Shares from the closing date of the Share Issuance (the “Closing Date”) until 180 days thereafter to the extent the issued and outstanding AHL Class A Common Shares beneficially owned by Apollo and certain of its related parties and employees (collectively, the “Apollo Parties”) (inclusive of AHL Class A Common Shares over which any such persons have a valid proxy) do not equal at least 35% of the issued and outstanding AHL Class A Common Shares, on a fully diluted basis (the “Conditional Right”); • A representative of the Apollo Operating Group will have the right to purchase up to that number of AHL Class A Common Shares that would increase by up to 5% the percentage of the issued and outstanding AHL Class A Common Shares beneficially owned by the Apollo Parties (inclusive of AHL Class A Common Shares over which any such persons have a valid proxy), calculated on a fully diluted basis (the “Facility Right”, and together with the Share Issuance and the Conditional Right, the “Share Transactions”); • AHL will make certain amendments to the Twelfth Amended and Restated Bye-laws of AHL (the “Bye-laws”), by way of amending and restating the Bye-laws (the “Thirteenth Amended and Restated Bye-laws”), which include, among other items, the elimination of AHL’s current multi-class share structure. The consummation of the Share Issuance and the other transactions contemplated by the Transaction Agreement are subject to the satisfaction or waiver of specified closing conditions, including (i) the approval of the Thirteenth Amended and Restated Bye-laws and the Share Transactions by AHL’s shareholders, (ii) the receipt of required governmental and regulatory approvals for the Share Transactions, and the approval of the NYSE for the listing of the AHL Class A Common Shares to be issued by AHL in connection with the Share Issuance, (iii) the absence of any applicable law or regulation or order that prohibits the transactions contemplated by the Transaction Agreement, and the absence of any pending or threatened proceeding by any governmental entity or any investigation by any governmental entity seeking any such order, and (iv) certain other customary closing conditions, including, among other things, delivery of certain transaction documents contemplated by the Transaction Agreement, accuracy of representations and warranties and compliance with covenants by the parties. The Company expects the Transaction Agreement to have a material impact on its condensed consolidated financial statements related to its investment in Athene Holding and corresponding Non-controlling Interests. Upon consummation of the Transaction Agreement, the fair value of the Company’s investment in Athene Holding will be calculated using the closing market price of AHL Class A Common Shares, less a discount due to a lack of marketability, as a result of a lock-up on existing and newly acquired AHL Class A Common Shares for three years from the initial closing date. In addition, the Company may have to consolidate certain entities in which it has an indirect ownership interest through its investment in Athene Holding, with a portion attributable to Non-controlling Interests. Dividends On October 31, 2019 , the Company declared a cash dividend of $0.50 per share of Class A Common Stock, which will be paid on November 29, 2019 to holders of record at the close of business on November 20, 2019 . On October 31, 2019 , the Company declared a cash dividend of $0.398438 per share of Series A Preferred Stock and Series B Preferred Stock, which will be paid on December 16, 2019 to holders of record at the close of business on November 29, 2019 .

SUMMARY OF SIGNIFICANT ACCOUN_2

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	9 Months Ended
	Sep. 30, 2019
Accounting Policies [Abstract]
Organization of the Company	Organization of the Company Effective September 5, 2019, Apollo Global Management, Inc. converted from a Delaware limited liability company named Apollo Global Management, LLC to a Delaware corporation named Apollo Global Management, Inc. The Company was formed as a Delaware limited liability company on July 3, 2007, and, until the Conversion, was managed by AGM Management, LLC, which is indirectly wholly-owned and controlled by Leon Black, Joshua Harris and Marc Rowan, its Managing Partners. As of September 30, 2019 , the Company owned, through six intermediate holding companies, 55.2% of the economic interests of, and operated and controlled all of the businesses and affairs of, the Apollo Operating Group through its wholly owned subsidiaries. AP Professional Holdings, L.P., a Cayman Islands exempted limited partnership (“Holdings”), is the entity through which the Managing Partners and certain of the Company’s other partners (the “Contributing Partners”) indirectly beneficially own interests in each of the entities that comprise the Apollo Operating Group (“AOG Units”). As of September 30, 2019 , Holdings owned the remaining 44.8% of the economic interests in the Apollo Operating Group. The Company consolidates the financial results of the Apollo Operating Group and its consolidated subsidiaries. Holdings’ ownership interest in the Apollo Operating Group is reflected as a Non-Controlling Interest in the accompanying condensed consolidated financial statements.
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements are prepared in accordance with U.S. GAAP for interim financial information and instructions to the Quarterly Report on Form 10-Q. The condensed consolidated financial statements and these notes are unaudited and exclude some of the disclosures required in annual financial statements. Management believes it has made all necessary adjustments (consisting only of normal recurring items) so that the condensed consolidated financial statements are presented fairly and that estimates made in preparing its condensed consolidated financial statements are reasonable and prudent. The operating results presented for interim periods are not necessarily indicative of the results that may be expected for any other interim period or for the entire year. These condensed consolidated financial statements should be read in conjunction with the annual financial statements included in the 2018 Annual Report. The condensed consolidated financial statements include the accounts of the Company, its wholly-owned or majority-owned subsidiaries, the consolidated entities which are considered to be variable interest entities (“VIEs”) and for which the Company is considered the primary beneficiary, and certain entities which are not considered VIEs but which the Company controls through a majority voting interest. Intercompany accounts and transactions, if any, have been eliminated upon consolidation. Certain reclassifications, when applicable, have been made to the prior periods’ condensed consolidated financial statements and notes to conform to the current period’s presentation and are disclosed accordingly.
Consolidation	Consolidation The types of entities with which Apollo is involved generally include subsidiaries (e.g., general partners and management companies related to the funds the Company manages), entities that have all the attributes of an investment company (e.g., funds) and securitization vehicles (e.g., CLOs). Each of these entities is assessed for consolidation on a case by case basis depending on the specific facts and circumstances surrounding that entity. Pursuant to the consolidation guidance, the Company first evaluates whether it holds a variable interest in an entity. Fees that are customary and commensurate with the level of services provided, and where the Company does not hold other economic interests in the entity that would absorb more than an insignificant amount of the expected losses or returns of the entity, would not be considered a variable interest. Apollo factors in all economic interests including proportionate interests through related parties, to determine if such interests are considered a variable interest. As Apollo’s interests in many of these entities are solely through market rate fees and/or insignificant indirect interests through related parties, Apollo is not considered to have a variable interest in many of these entities and no further consolidation analysis is performed. For entities where the Company has determined that it does hold a variable interest, the Company performs an assessment to determine whether each of those entities qualify as a VIE. The determination as to whether an entity qualifies as a VIE depends on the facts and circumstances surrounding each entity and therefore certain of Apollo’s funds may qualify as VIEs under the variable interest model whereas others may qualify as voting interest entities (“VOEs”) under the voting interest model. The granting of substantive kick-out rights is a key consideration in determining whether a limited partnership or similar entity is a VIE and whether or not that entity should be consolidated. Under the variable interest model, Apollo consolidates those entities where it is determined that the Company is the primary beneficiary of the entity. The Company is determined to be the primary beneficiary when it has a controlling financial interest in the VIE, which is defined as possessing both (i) the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and (ii) the obligation to absorb losses of the VIE or the right to receive benefits from the VIE that could potentially be significant to the VIE. When Apollo alone is not considered to have a controlling financial interest in the VIE but Apollo and its related parties under common control in the aggregate have a controlling financial interest in the VIE, Apollo will be deemed the primary beneficiary if it is the party that is most closely associated with the VIE. When Apollo and its related parties not under common control in the aggregate have a controlling financial interest in the VIE, Apollo would be deemed to be the primary beneficiary if substantially all the activities of the entity are performed on behalf of Apollo. Apollo determines whether it is the primary beneficiary of a VIE at the time it becomes initially involved with the VIE and reconsiders that conclusion continuously. Investments and redemptions (either by Apollo, related parties of Apollo or third parties) or amendments to the governing documents of the respective entity may affect an entity’s status as a VIE or the determination of the primary beneficiary. Assets and liabilities of the consolidated VIEs are primarily shown in separate sections within the condensed consolidated statements of financial condition. Changes in the fair value of the consolidated VIEs’ assets and liabilities and related interest, dividend and other income and expenses are presented within net gains from investment activities of consolidated variable interest entities in the condensed consolidated statements of operations. The portion attributable to Non-Controlling Interests is reported within net income attributable to Non-Controlling Interests in the condensed consolidated statements of operations. For additional disclosures regarding VIEs, see note 5 . Under the voting interest model, Apollo consolidates those entities it controls through a majority voting interest. Apollo does not consolidate those VOEs in which substantive kick-out rights have been granted to the unrelated investors to either dissolve the fund or remove the general partner.
Cash and Cash Equivalents and Restricted Cash	Cash and Cash Equivalents Apollo considers all highly liquid short-term investments with original maturities of three months or less when purchased to be cash equivalents. Cash and cash equivalents include money market funds and U.S. Treasury securities with original maturities of three months or less when purchased. Interest income from cash and cash equivalents is recorded in interest income in the condensed consolidated statements of operations. The carrying values of the money market funds and U.S. Treasury securities were $302.3 million and $231.8 million as of September 30, 2019 and December 31, 2018 , respectively, which approximate their fair values due to their short-term nature and are categorized as Level I within the fair value hierarchy. Substantially all of the Company’s cash on deposit is in interest bearing accounts with major financial institutions and exceed insured limits. Restricted Cash Restricted cash includes cash held in reserve accounts used to make required payments in respect of the 2039 Senior Secured Guaranteed Notes. Restricted cash also includes cash deposited at a bank, which is pledged as collateral in connection with leased premises.
U.S. Treasury securities, at fair value	U.S. Treasury securities, at fair value U.S. Treasury securities, at fair value includes U.S. Treasury bills with original maturities greater than three months when purchased. These securities are recorded at fair value. Interest income on such securities is separately presented from the overall change in fair value and is recognized in interest income in the condensed consolidated statements of operations. Any remaining change in fair value of such securities, that is not recognized as interest income, is recognized in net gains (losses) from investment activities in the condensed consolidated statements of operations.
Fair Value of Financial Instruments	Fair Value of Financial Instruments Apollo has elected the fair value option for the Company’s investment in Athene Holding, the assets and liabilities of certain of its consolidated VIEs (including CLOs), the Company’s U.S. Treasury securities with original maturities greater than three months when purchased, and certain of the Company’s other investments. Such election is irrevocable and is applied to financial instruments on an individual basis at initial recognition. The fair value of a financial instrument is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date under current market conditions. Except for the Company’s debt obligations, financial instruments are generally recorded at fair value or at amounts whose carrying values approximate fair value. The actual realized gains or losses will depend on, among other factors, future operating results, the value of the assets and market conditions at the time of disposition, any related transaction costs and the timing and manner of sale, all of which may ultimately differ significantly from the assumptions on which the valuations were based. Fair Value Hierarchy U.S. GAAP establishes a hierarchical disclosure framework which prioritizes and ranks the level of market price observability used in measuring financial instruments at fair value. Market price observability is affected by a number of factors, including the type of financial instrument, the characteristics specific to the financial instrument and the state of the marketplace, including the existence and transparency of transactions between market participants. Financial instruments with readily available quoted prices in active markets generally will have a higher degree of market price observability and a lesser degree of judgment used in measuring fair value. Financial instruments measured and reported at fair value are classified and disclosed based on the observability of inputs used in the determination of fair values, as follows: Level I - Quoted prices are available in active markets for identical financial instruments as of the reporting date. The types of financial instruments included in Level I include listed equities and debt. The Company does not adjust the quoted price for these financial instruments, even in situations where the Company holds a large position and the sale of such position would likely deviate from the quoted price. Level II - Pricing inputs are other than quoted prices in active markets, which are either directly or indirectly observable as of the reporting date, and fair value is determined through the use of models or other valuation methodologies. Financial instruments that are generally included in this category include corporate bonds and loans, less liquid and restricted equity securities and certain over-the-counter derivatives where the fair value is based on observable inputs. These financial instruments exhibit higher levels of liquid market observability as compared to Level III financial instruments. Level III - Pricing inputs are unobservable for the financial instrument and includes situations where there is little observable market activity for the financial instrument. The inputs into the determination of fair value may require significant management judgment or estimation. Financial instruments that are included in this category generally include general and limited partner interests in corporate private equity and real assets funds, opportunistic credit funds, distressed debt and non-investment grade residual interests in securitizations and CDOs and CLOs where the fair value is based on observable inputs as well as unobservable inputs. When a security is valued based on broker quotes, the Company subjects those quotes to various criteria in making the determination as to whether a particular financial instrument would qualify for classification as Level II or Level III. These criteria include, but are not limited to, the number and quality of the broker quotes, the standard deviations of the observed broker quotes, and the percentage deviation from independent pricing services. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, a financial instrument’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the financial instrument when the fair value is based on unobservable inputs.
Equity Method Investments	Equity Method Investments For investments in entities over which the Company exercises significant influence but which do not meet the requirements for consolidation and for which the Company has not elected the fair value option, the Company uses the equity method of accounting, whereby the Company records its share of the underlying income or loss of such entities. The Company’s share of the underlying net income or loss of such entities is recorded in principal investment income in the condensed consolidated statements of operations. The carrying amounts of equity method investments are recorded in investments in the condensed consolidated statements of financial condition. As the underlying entities that the Company manages and invests in are, for U.S. GAAP purposes, primarily investment companies which reflect their investments at estimated fair value, the carrying value of the Company’s equity method investments in such entities approximates fair value.
Financial Instruments held by Consolidated VIEs	Financial Instruments held by Consolidated VIEs The Company measures both the financial assets and financial liabilities of the consolidated CLOs in its condensed consolidated financial statements using the fair value of the financial assets of the consolidated CLOs, which are more observable than the fair value of the financial liabilities of the consolidated CLOs. As a result, the financial assets of the consolidated CLOs are measured at fair value and the financial liabilities are measured in consolidation as: (i) the sum of the fair value of the financial assets and the carrying value of any non-financial assets that are incidental to the operations of the CLOs less (ii) the sum of the fair value of any beneficial interests retained by the Company (other than those that represent compensation for services) and the Company’s carrying value of any beneficial interests that represent compensation for services. The resulting amount is allocated to the individual financial liabilities (other than the beneficial interest retained by the Company) using a reasonable and consistent methodology. Under the measurement alternative, net income attributable to Apollo Global Management, Inc. reflects the Company’s own economic interests in the consolidated CLOs including (i) changes in the fair value of the beneficial interests retained by the Company and (ii) beneficial interests that represent compensation for collateral management services. The consolidated VIEs hold investments that could be traded over-the-counter. Investments in securities that are traded on a securities exchange or comparable over-the-counter quotation systems are valued based on the last reported sale price at that date. If no sales of such investments are reported on such date, and in the case of over-the-counter securities or other investments for which the last sale date is not available, valuations are based on independent market quotations obtained from market participants, recognized pricing services or other sources deemed relevant, and the prices are based on the average of the “bid” and “ask” prices, or at ascertainable prices at the close of business on such day. Market quotations are generally based on valuation pricing models or market transactions of similar securities adjusted for security-specific factors such as relative capital structure priority and interest and yield risks, among other factors. When market quotations are not available, a model based approach is used to determine fair value.
Leases	Leases The Company determines if an arrangement is a lease or contains a lease at inception. Operating leases are included in lease assets and lease liabilities in the condensed consolidated statements of financial condition. The Company does not have any finance leases. Lease assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Lease assets and lease liabilities are recognized at the date of commencement of the lease (the “commencement date”) based on the present value of lease payments over the lease term. As most of the Company’s leases do not provide an implicit rate, the Company uses its derived incremental borrowing rate based on information available at commencement date in determining the present value of lease payments. The determination of an appropriate incremental borrowing rate requires judgment. The Company determined its incremental borrowing rate based on consideration of market conditions, the Company’s overall creditworthiness, and recent debt and preferred equity issuances. The Company adjusts its rate accordingly based on the term of the leases. Lease assets also include any lease payments made (e.g. pre-paid rent) and are reduced by any deferred rent liabilities arising from lease escalation provisions and lease incentives within the Company’s lease agreements. Accordingly, as of September 30, 2019 , the difference between lease assets and lease liabilities represents the Company’s deferred rent liabilities that are netted against the lease asset amount. Certain lease agreements contain lease escalation or lease incentive provisions based on the terms of the arrangement with the landlord. Lease escalations and lease incentives, if any, are recognized on a straight-line basis over the lease term. The Company’s lease agreements may also include options to extend or terminate the lease. Options to extend would not be included in the lease term until it is reasonably certain that the Company will exercise that option. Lease expense is recognized on a straight-line basis over the lease term and is recorded within general, administrative and other in the condensed consolidated statements of operations. The Company has lease agreements with non-lease components (e.g. estimated operating expenses associated with the lease), which are accounted for separately.
Other Assets	Other Assets Other assets primarily includes fixed assets, net, deferred equity-based compensation and prepaid expenses. During 2019, the presentation of intangible assets, net was combined with other assets on the condensed consolidated statements of financial condition and the prior period was recast to conform to the current presentation.
Deferred Revenue and Revenues	Deferred Revenue Apollo records deferred revenue, which is a type of contract liability, when consideration is received in advance of management services provided. Apollo also earns management fees subject to the Management Fee Offset (described below). When advisory and transaction fees are earned by the management company, the Management Fee Offset reduces the management fee obligation of the fund. When the Company receives cash for advisory and transaction fees, a certain percentage of such advisory and/or transaction fees, as applicable, is allocated as a credit to reduce future management fees, otherwise payable by such fund. Such credit is recorded as deferred revenue in the condensed consolidated statements of financial condition. A portion of any excess advisory and transaction fees may be required to be returned to the limited partners of certain funds upon such fund’s liquidation. As the management fees earned by the Company are presented on a gross basis, any Management Fee Offsets calculated are presented as a reduction to advisory and transaction fees in the condensed consolidated statements of operations. Additionally, Apollo earns advisory fees pursuant to the terms of the advisory agreements with certain of the portfolio companies that are owned by the funds Apollo manages. When Apollo receives a payment from a portfolio company that exceeds the advisory fees earned at that point in time, the excess payment is recorded as deferred revenue in the condensed consolidated statements of financial condition. The advisory agreements with the portfolio companies vary in duration and the associated fees are received monthly, quarterly or annually. Deferred revenue is reversed and recognized as revenue over the period that the agreed upon services are performed. There was $77.1 million of revenue recognized during the nine months ended September 30, 2019 that was previously deferred as of January 1, 2019. Under the terms of the funds’ partnership agreements, Apollo is normally required to bear organizational expenses over a set dollar amount and placement fees or costs in connection with the offering and sale of interests in the funds it manages to investors. The placement fees are payable to placement agents, who are independent third parties that assist in identifying potential investors, securing commitments to invest from such potential investors, preparing or revising offering and marketing materials, developing strategies for attempting to secure investments by potential investors and/or providing feedback and insight regarding issues and concerns of potential investors, when a limited partner either commits or funds a commitment to a fund. In certain instances the placement fees are paid over a period of time. Based on the management agreements with the funds, Apollo considers placement fees and organizational costs paid in determining if cash has been received in excess of the management fees earned. Placement fees and organizational costs are normally the obligation of Apollo but can be paid for by the funds. When these costs are paid by the fund, the resulting obligations are included within deferred revenue. The deferred revenue balance will also be reduced during future periods when management fees are earned but not paid. Revenues The Company’s revenues are reported in four separate categories that include (i) management fees; (ii) advisory and transaction fees, net; (iii) investment income, which is comprised of performance allocations and principal investment income; and (iv) incentive fees. On January 1, 2018, the Company adopted new revenue guidance issued by the FASB for recognizing revenue from contracts with customers. The new revenue guidance requires that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services (i.e., the transaction price). When determining the transaction price under the new revenue guidance, an entity may recognize variable consideration only to the extent that it is probable to not be significantly reversed. The new revenue guidance also requires improved disclosures to help users of financial statements better understand the nature, amount, timing, and uncertainty of revenue that is recognized. The Company has concluded that its management fees, advisory and transaction fees, and incentive fees are within the scope of the new revenue guidance. For incentive fees, the new revenue guidance delays the timing of certain revenues compared to the prior accounting treatment. These amounts were previously recognized in carried interest income in the condensed consolidated statements of operations and are now recognized within a separate line, incentive fees. Effective January 1, 2018, the Company implemented a change in accounting principle for performance allocations to be accounted for under guidance applicable to equity method investments, and therefore not within the scope of the new revenue guidance. The accounting change does not change the timing or amount of revenue recognized related to performance allocation arrangements. These amounts were previously recognized within carried interest income in the condensed consolidated statements of operations and carried interest receivable within the condensed consolidated statements of financial condition. As a result of the change in accounting principle, the Company recognizes performance allocations within investment income along with the related principal investment income (as further described below) in the condensed consolidated statements of operations and within the investments line in the condensed consolidated statements of financial condition. The Company applied this change in accounting principle on a full retrospective basis.
Management Fees	Management Fees Management fees are recognized over time during the periods in which the related services are performed in accordance with the contractual terms of the related agreement. Management fees are generally based on (1) a percentage of the capital committed during the commitment period, and thereafter based on the remaining invested capital of unrealized investments, or (2) net asset value, gross assets or as otherwise defined in the respective agreements. Included in management fees are certain expense reimbursements where the Company is considered the principal under the agreements and is required to record the expense and related reimbursement revenue on a gross basis.
Advisory and Transaction Fees, Net	Advisory and Transaction Fees, Net Advisory fees, including management consulting fees and directors’ fees, are generally recognized over time as the underlying services are provided in accordance with the contractual terms of the related agreement. The Company receives such fees in exchange for ongoing management consulting services provided to portfolio companies of funds it manages. Transaction fees, including structuring fees and arranging fees are generally recognized at a point in time when the underlying services rendered are complete. The amounts due from fund portfolio companies are recorded in due from related parties, which is discussed further in note 14 . Under the terms of the limited partnership agreements for certain funds, the management fee payable by the funds may be subject to a reduction based on a certain percentage of such advisory and transaction fees, net of applicable broken deal costs (“Management Fee Offset”). Advisory and transaction fees are presented net of the Management Fee Offset in the condensed consolidated statements of operations. Underwriting fees, which are also included within advisory and transaction fees, net, include gains, losses and fees, arising from securities offerings in which one of the Company’s subsidiaries participates in the underwriter syndicate. Underwriting fees are recognized at a point in time when the underwriting is completed. Underwriting fees recognized but not received are recorded in other assets on the condensed consolidated statements of financial condition. During the normal course of business, the Company incurs certain costs related to certain transactions that are not consummated (“broken deal costs”). These costs (e.g., research costs, due diligence costs, professional fees, legal fees and other related items) are determined to be broken deal costs upon management’s decision to no longer pursue the transaction. In accordance with the related fund agreement, in the event the deal is deemed broken, all of the costs are reimbursed by the funds and then included as a component of the calculation of the Management Fee Offset. If a deal is successfully completed, Apollo is reimbursed by the fund or fund’s portfolio company for all costs incurred and no offset is generated. As the Company acts as an agent for the funds it manages, any transaction costs incurred and paid by the Company on behalf of the respective funds relating to successful or broken deals are recorded net on the Company’s condensed consolidated statements of operations, and any receivable from the respective funds is recorded in due from related parties on the condensed consolidated statements of financial condition.
Investment Income	Investment Income Investment income is comprised of performance allocations and principal investment income. Performance Allocations Performance allocations are a type of performance revenue (i.e., income earned based on the extent to which an entity’s performance exceeds predetermined thresholds). Performance allocations are generally structured from a legal standpoint as an allocation of capital in which the Company’s capital account receives allocations of the returns of an entity when those returns exceed predetermined thresholds. The determination of which performance revenues are considered performance allocations is primarily based on the terms of an agreement with the entity. As noted above, as a result of a change in accounting principle, the Company recognizes performance allocations within investment income along with the related principal investment income (as described further below) in the condensed consolidated statements of operations and within the investments line in the condensed consolidated statements of financial condition. Principal Investment Income Principal investment income includes the Company’s income or loss from equity method investments and certain other investments in entities in which the Company is generally eligible to receive performance allocations. Income from equity method investments includes the Company’s share of net income or loss generated from its investments, which are not consolidated, but in which the Company exerts significant influence. Prior to the change in accounting principle noted above, income from equity method investments was included within other income (loss) in the condensed consolidated
Incentive Fees	Incentive Fees Incentive fees are a type of performance revenue. Incentive fees differ from performance allocations in that incentive fees do not represent an allocation of capital but rather a contractual fee arrangement with the entity. Incentive fees are considered a form of variable consideration under the new revenue recognition guidance as they are subject to clawback or reversal and therefore must be deferred until the fees are probable to not be significantly reversed. Accrued but unpaid incentive fees are reported within incentive fees receivable in the Company’s condensed consolidated statements of financial condition. As noted earlier, prior to the adoption of the new revenue recognition guidance, incentive fees were recognized on an assumed liquidation basis. The Company’s incentive fees primarily relate to the credit segment and are generally received from CLOs, managed accounts and AINV.
Equity-Based Compensation	Equity-Based Compensation Equity-based awards granted to employees and non-employees as compensation are measured based on the grant date fair value of the award. Equity-based awards that do not require future service (i.e., vested awards) are expensed immediately. Equity-based employee awards that require future service are expensed over the relevant service period. In addition, certain restricted share units (“RSUs”) granted by the Company vest based on both continued service and the Company’s receipt of performance revenues, within prescribed periods, sufficient to cover the associated equity-based compensation expense. In accordance with U.S. GAAP, equity-based compensation expense for such awards, if and when granted, will be recognized on an accelerated recognition method over the requisite service period to the extent the performance revenue metrics are met or deemed probable. The Company accounts for forfeitures of equity-based awards when they occur.
Profit Sharing	Profit Sharing Profit sharing expense and profit sharing payable primarily consist of a portion of performance revenues earned from certain funds that are allocated to employees, former employees and Contributing Partners. Profit sharing amounts are recognized as the related performance revenues are earned. Accordingly, profit sharing amounts can be reversed during periods when there is a decline in performance revenues that were previously recognized. Profit sharing amounts are generally not paid until the related performance revenue is distributed to the general partner upon realization of the fund’s investments. Under certain profit sharing arrangements, the Company requires that a portion of certain of the performance revenues distributed to its employees be used to purchase restricted shares of Class A Common Stock issued under the Company’s 2007 Omnibus Equity Incentive Plan, which, effective as of July 22, 2019, was amended, restated and renamed the 2019 Omnibus Equity Incentive Plan (the “Equity Plan”). Prior to distribution of the performance revenue, the Company records the value of the equity-based awards expected to be granted in other assets and other liabilities within the condensed consolidated statements of financial condition. Such equity-based awards are recorded as equity-based compensation expense over the relevant service period once granted. Additionally, profit sharing amounts previously distributed may be subject to clawback from employees, former employees and Contributing Partners. When applicable, the accrual for potential clawback of previously distributed profit sharing amounts, which is a component of due from related parties on the condensed consolidated statements of financial condition, represents all amounts previously distributed to employees, former employees and Contributing Partners that would need to be returned to the general partner if the Apollo funds were to be liquidated based on the fair value of the underlying funds’ investments as of the reporting date. The actual general partner receivable, however, would not become realized until the end of a fund’s life. Profit sharing payable also includes contingent consideration obligations that were recognized in connection with certain Apollo acquisitions. Changes in the fair value of the contingent consideration obligations are reflected in the Company’s condensed consolidated statements of operations as profit sharing expense. The Company has a performance-based incentive arrangement for certain Apollo partners and employees designed to more closely align compensation on an annual basis with the overall realized performance of the Company. This arrangement enables certain partners and employees to earn discretionary compensation based on performance revenue earned by the Company in a given year, which amounts are reflected in profit sharing expense in the accompanying condensed consolidated financial statements.
401(k) Savings Plan	401(k) Savings Plan The Company sponsors a 401(k) savings plan (the “401(k) Plan”) whereby U.S.-based employees are entitled to participate in the 401(k) Plan based upon satisfying certain eligibility requirements. The Company matches 50% of eligible annual employee contributions up to 3% of the eligible employees’ annual compensation. Matching contributions vest after three years of service.
General, Administrative and Other	General, Administrative and Other General, administrative and other primarily includes professional fees, occupancy, depreciation and amortization, travel, information technology and administration expenses.
Income Taxes	Income Taxes Prior to the Conversion, certain entities in the Apollo Operating Group operated as partnerships for U.S. federal income tax purposes. As a result, these members of the Apollo Operating Group were not subject to U.S. federal income taxes. However, certain of these entities were subject to New York City unincorporated business taxes (“NYC UBT”) and certain non-U.S. entities were subject to non-U.S. corporate income taxes. Effective September 5, 2019, Apollo Global Management, LLC converted from a Delaware limited liability company to a Delaware corporation named Apollo Global Management, Inc. Subsequent to the Conversion, we expect that all of the income the Company earns will be subject to U.S. corporate income taxes, which could result in an overall higher income tax expense (or benefit) in periods subsequent to the Conversion. Significant judgment is required in determining tax expense and in evaluating tax positions, including evaluating uncertainties. The Company recognizes the tax benefits of uncertain tax positions only where the position is “more likely than not” to be sustained upon examination, including resolutions of any related appeals or litigation processes, based on the technical merits of the position. The tax benefit is measured as the largest amount of benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. If a tax position is not considered more likely than not to be sustained, then no benefits of the position are recognized. The Company’s tax positions are reviewed and evaluated quarterly to determine whether or not the Company has uncertain tax positions that require financial statement recognition. Deferred tax assets and liabilities are recognized for the expected future tax consequences of differences between the carrying amount of assets and liabilities and their respective tax basis using currently enacted tax rates. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period during which the change is enacted. Deferred tax assets are reduced by a valuation allowance when it is more likely than not that some portion or all of the deferred tax assets will not be realized.
Use of Estimates	Use of Estimates The preparation of the condensed consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the condensed consolidated financial statements, the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. Apollo’s most significant estimates include goodwill, intangible assets, income taxes, performance allocations, incentive fees, contingent consideration obligation related to an acquisition, non-cash compensation, and fair value of investments and debt. Actual results could differ materially from those estimates.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Recently Issued Accounting Standards Effective on January 1, 2019 In February 2016, the FASB issued a new standard related to leases to increase transparency and comparability among organizations by requiring the recognition of right-of-use lease assets and lease liabilities on the statements of financial condition. The most significant among the changes in the standard is the recognition of right-of-use lease assets and lease liabilities by lessees for those leases classified as operating leases. Under the standard, disclosures are required to meet the objectives of enabling users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases. The Company adopted the standard effective January 1, 2019 under the simplified transition method. The simplified transition method allows companies to forgo the comparative reporting requirements initially required under the modified retrospective transition approach and apply the new guidance prospectively. The Company also elected to use the practical expedients available under the standard whereby the Company would not need to reassess whether an arrangement is or contains a lease, lease classification, and the accounting for initial direct costs. The adoption of the standard had an impact on the Company’s condensed consolidated statements of financial condition but did not have an impact on the Company’s condensed consolidated statements of operations, condensed consolidated statements of cash flows or beginning accumulated deficit. The most significant impact was the recognition of right-of-use lease assets and lease liabilities for operating leases. Refer to the condensed consolidated statements of financial condition and note 8 for further information on the impact of the adoption of the standard on the Company’s condensed consolidated financial statements. Recently Issued Accounting Standards Effective on January 1, 2020 In June 2016, the FASB issued guidance intended to provide financial statement users with more useful information about the expected credit losses on financial instruments held by a reporting entity at each reporting date. To achieve this objective, the new guidance replaces the incurred loss methodology in current GAAP with a methodology that reflects expected credit losses. The new guidance will affect entities to varying degrees depending on the credit quality of the assets held by the entity, their duration, and how the entity applies current GAAP. The new guidance is effective for the Company on January 1, 2020 and early adoption is permitted. The new guidance is not expected to have a material impact on the condensed consolidated financial statements of the Company. In January 2017, the FASB issued guidance intended to simplify the test for goodwill impairment. The new guidance removes the requirement to perform a hypothetical purchase price allocation to measure goodwill impairment (Step 2). Under the new guidance, a goodwill impairment is calculated as the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill in the reporting unit. The guidance is effective for annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019, and should be performed prospectively. Early adoption is permitted for interim or annual goodwill impairment tests performed after January 1, 2017. The guidance is not expected to have a material impact on the condensed consolidated financial statements of the Company.

(2) Cash paid for tax liabilities associated with net share settlement was $48.8 million and $40.3 million for the nine months ended September 30, 2019 and 2018 , respectively. (3) Certain Apollo employees receive a portion of the profit sharing proceeds of certain funds in the form of (a) restricted shares of Class A Common Stock of AGM Inc. that they are required to purchase with such proceeds or (b) RSUs, in each case which equity-based awards generally vest over three years . These equity-based awards are granted under the Company's Equity Plan. To prevent dilution on account of these awards, Apollo may, in its discretion, repurchase of shares of Class A Common Stock on the open market and retire them. During the nine months ended September 30, 2019 and 2018 , we issued 163,024 and 673,326 of such restricted shares and 102,089 and 75,636 of such RSUs under the Equity Plan, respectively, and repurchased 265,113 and 830,438 shares of Class A Common Stock in open-market transactions not pursuant to a publicly-announced repurchase plan or program, respectively. In addition, there were 1,865 and 26,857 restricted shares forfeited during the nine months ended September 30, 2019 and 2018 , respectively.
Schedule of Dividends and Distributions	The table below presents information regarding the quarterly dividends and distributions which were made at the sole discretion of the Former Manager of the Company prior to the Conversion (in millions, except per share data). Certain subsidiaries of AGM Inc. may be subject to U.S. federal, state, local and non-U.S. income taxes at the entity level and may pay taxes and/or make payments under the tax receivable agreement in a given fiscal year; therefore, the net amounts ultimately distributed by AGM Inc. to its Class A Common Stockholders in respect of each fiscal year are generally expected to be less than the net amounts distributed to AOG Unitholders. Subsequent to the Conversion, distributions from AGM Inc. are referred to as dividends.
