Organization, Consolidation and Presentation of Financial Statements [Abstract]
ORGANIZATION AND BASIS OF PRESENTATION	ORGANIZATION AND BASIS OF PRESENTATION Oaktree Capital Group, LLC (together with its subsidiaries, “Oaktree” or the “Company”) is a leader among global investment managers specializing in alternative investments. Oaktree emphasizes an opportunistic, value-oriented and risk-controlled approach to investments in credit, private equity, real assets and listed equities. Funds managed by Oaktree (the “Oaktree funds”) include commingled funds, separate accounts, collateralized loan obligation vehicles (“CLOs”) and publicly-traded business development companies (“BDCs”). Commingled funds include open-end and closed-end limited partnerships in which the Company makes an investment and for which it serves as the general partner. CLOs are structured finance vehicles in which the Company typically makes an investment and for which it serves as collateral manager. Oaktree Capital Group, LLC is a Delaware limited liability company that was formed on April 13, 2007. The Company is owned by its Class A and Class B unitholders and its preferred unitholders. Oaktree Capital Group Holdings GP, LLC acts as the Company’s manager and is the general partner of Oaktree Capital Group Holdings, L.P. (“OCGH”), which owns 100% of the Company’s outstanding Class B units. OCGH is owned by the Company’s senior executives, current and former employees, and certain other investors (collectively, the “OCGH unitholders”). The Company’s operations are conducted through a group of operating entities collectively referred to as the “Oaktree Operating Group.” OCGH has a direct economic interest in the Oaktree Operating Group and the Company has an indirect economic interest in the Oaktree Operating Group. The interests in the Oaktree Operating Group are referred to as the “Oaktree Operating Group units.” An Oaktree Operating Group unit is not a separate legal interest but represents one limited partnership interest in each of the Oaktree Operating Group entities. Class A units are entitled to one vote per unit. Class B units are entitled to ten votes per unit and do not represent an economic interest in the Company. The number of Class B units held by OCGH increases or decreases in response to corresponding changes in OCGH’s economic interest in the Oaktree Operating Group; consequently, the OCGH unitholders’ economic interest in the Oaktree Operating Group is reflected within non-controlling interests in consolidated subsidiaries in the accompanying condensed consolidated financial statements. Basis of Presentation The accompanying unaudited condensed consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information. The condensed consolidated financial statements, including these notes, are unaudited and exclude some of the disclosures required in annual financial statements. Management believes it has made all necessary adjustments (consisting of only normal recurring items) such 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. The condensed consolidated financial statements include the accounts of the Company, its wholly-owned or majority-owned subsidiaries and entities in which the Company is deemed to have a direct or indirect controlling financial interest based on either a variable interest model or voting interest model. Certain of the Oaktree funds consolidated by the Company are investment companies that follow a specialized basis of accounting established by GAAP. All intercompany transactions and balances have been eliminated in consolidation. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements of the Company for the year ended December 31, 2017 included in the Company’s Annual Report on Form 10-K filed with the U.S. Securities and Exchange Commission (“SEC”) on February 23, 2018.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	Jun. 30, 2018
Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Accounting Policies of the Company Consolidation The Company consolidates entities in which it has a direct or indirect controlling financial interest based on either a variable interest model or voting interest model. A limited partnership or similar entity is a variable interest entity (“VIE”) if the unaffiliated limited partners do not have substantive kick-out or participating rights. Most of the Oaktree funds are VIEs because they have not granted unaffiliated limited partners substantive kick-out or participating rights. The Company consolidates those VIEs in which it is the primary beneficiary. An entity is deemed to be the primary beneficiary if it holds a controlling financial interest. A controlling financial interest is defined as (a) the power to direct the activities of a VIE that most significantly impact the entity’s economic performance and (b) the obligation to absorb losses of the entity or the right to receive benefits from the entity that could potentially be significant to the VIE. The consolidation guidance requires an analysis to determine (a) whether an entity in which the Company holds a variable interest is a VIE and (b) whether the Company’s involvement, through holding interests directly or indirectly in the entity or contractually through other variable interests (e.g., management and performance-based fees), would give it a controlling financial interest. A decision maker’s fee arrangement is not considered a variable interest if (a) it is compensation for services provided, commensurate with the level of effort required to provide those services, and part of a compensation arrangement that includes only terms, conditions or amounts that are customarily present in arrangements for similar services negotiated at arm’s length (“at-market”), and (b) the decision maker does not hold any other variable interests that absorb more than an insignificant amount of the potential VIE’s expected residual returns. The Company determines whether it is the primary beneficiary of a VIE at the time it becomes involved with a VIE and reconsiders that conclusion at each reporting date. In evaluating whether the Company is the primary beneficiary, the Company evaluates its economic interests in the entity held either directly by the Company or indirectly through related parties. The consolidation analysis can generally be performed qualitatively; however, if it is not readily apparent that the Company is not the primary beneficiary, a quantitative analysis may also be performed. Investments and redemptions (either by the Company, affiliates of the Company or third parties) or amendments to the governing documents of the respective Oaktree funds could affect an entity’s status as a VIE or the determination of the primary beneficiary. The Company does not consolidate most of the Oaktree funds because it is not the primary beneficiary of those funds due to the fact that its fee arrangements are considered at-market and thus not deemed to be variable interests, and it does not hold any other interests in those funds that are considered to be more than insignificant. Please see note 5 for more information regarding both consolidated and unconsolidated VIEs. For entities that are not VIEs, consolidation is evaluated through a majority voting interest model. “Consolidated funds” refers to Oaktree-managed funds and CLOs that the Company is required to consolidate. When funds or CLOs are consolidated, the Company reflects the assets, liabilities, revenues, expenses and cash flows of the funds or CLOs on a gross basis, and the majority of the economic interests in those funds or CLOs, which are held by third-party investors, are reflected as non-controlling interests in consolidated funds or debt obligations of CLOs in the condensed consolidated financial statements. All of the revenues earned by the Company as investment manager of the consolidated funds are eliminated in consolidation. However, because the eliminated amounts are earned from and funded by third-party investors, the consolidation of a fund does not impact net income or loss attributable to the Company. Certain entities in which the Company has the ability to exert significant influence, including unconsolidated Oaktree funds for which the Company acts as general partner, are accounted for under the equity method of accounting. Non-controlling Redeemable Interests in Consolidated Funds The Company records non-controlling interests to reflect the economic interests of the unaffiliated limited partners. These interests are presented as non-controlling redeemable interests in consolidated funds within the condensed consolidated statements of financial condition, outside of the permanent capital section. Limited partners in open-end and evergreen funds generally have the right to withdraw their capital, subject to the terms of the respective limited partnership agreements, over periods ranging from one month to three years . While limited partners in consolidated closed-end funds generally have not been granted redemption rights, these limited partners do have withdrawal or redemption rights in certain limited circumstances that are beyond the control of the Company, such as instances in which retaining the limited partnership interest could cause the limited partner to violate a law, regulation or rule. The allocation of net income or loss to non-controlling redeemable interests in consolidated funds is based on the relative ownership interests of the unaffiliated limited partners after the consideration of contractual arrangements that govern allocations of income or loss. At the consolidated level, potential incentives are allocated to non-controlling redeemable interests in consolidated funds until such incentives become allocable to the Company under the substantive contractual terms of the limited partnership agreements of the funds. Non-controlling Interests in Consolidated Funds Non-controlling interests in consolidated funds represent the equity interests held by third-party investors in CLOs that had not yet priced as of the respective period end. All non-controlling interests in those CLOs are attributed a share of income or loss arising from the respective CLO based on the relative ownership interests of third-party investors after consideration of contractual arrangements that govern allocations of income or loss. Investors in those CLOs are generally unable to redeem their interests until the respective CLO liquidates, is called or otherwise terminates. Non-controlling Interests in Consolidated Subsidiaries Non-controlling interests in consolidated subsidiaries reflect the portion of unitholders’ capital attributable to OCGH unitholders (“OCGH non-controlling interest”) and third parties. All non-controlling interests in consolidated subsidiaries are attributed a share of income or loss in the respective consolidated subsidiary based on the relative economic interests of the OCGH unitholders or third parties after consideration of contractual arrangements that govern allocations of income or loss. Please see note 13 for more information. Acquisitions The Company accounts for business combinations using the acquisition method of accounting, which requires the use of estimates and judgment to measure the fair value of identifiable tangible and intangible assets acquired, liabilities assumed, and non-controlling interests in the acquiree as of the acquisition date. Contingent consideration that is determined to be part of the business combination is recognized at fair value as of the acquisition date and is included in the purchase price. Transaction costs are expensed as incurred. Transactions that do not meet the definition of a business are accounted for as asset acquisitions. The cost of an asset acquisition is allocated to the individual assets acquired and liabilities assumed on a relative fair value basis. Transaction costs are included in the cost of the acquisition and no goodwill is recognized. Goodwill and Intangibles Goodwill represents the excess of cost over the fair value of identifiable net assets of acquired businesses. Goodwill has an indefinite useful life and is not amortized, but instead is tested for impairment annually in the fourth quarter of each fiscal year, or more frequently when events or circumstances indicate that impairment may have occurred. The Company’s acquired identifiable intangible assets primarily relate to contractual rights to earn future management fees and incentive income. Finite-lived intangible assets are amortized over their estimated useful lives, which range from seven to 25 years, and are reviewed for impairment whenever events or circumstances indicate that the carrying amount of the asset may not be recoverable. Fair Value of Financial Instruments GAAP establishes a hierarchical disclosure framework that prioritizes the inputs used in measuring financial instruments at fair value into three levels based on their market observability. Market price observability is affected by a number of factors, such as the type of instrument and the characteristics specific to the instrument. Financial instruments with readily available quoted prices from an active market or for which fair value can be measured based on actively quoted prices generally will have a higher degree of market price observability and a lesser degree of judgment inherent in measuring fair value. Financial assets and liabilities measured and reported at fair value are classified as follows: • Level I – Quoted unadjusted prices for identical instruments in active markets to which the Company has access at the date of measurement. The types of investments in Level I include exchange-traded equities, debt and derivatives with quoted prices. • Level II – Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs are directly or indirectly observable. Level II inputs include interest rates, yield curves, volatilities, prepayment risks, loss severities, credit risks and default rates. The types of investments in Level II generally include corporate bonds and loans, government and agency securities, less liquid and restricted equity investments, over-the-counter traded derivatives, debt obligations of consolidated CLOs, and other investments where the fair value is based on observable inputs. • Level III – Valuations for which one or more significant inputs are unobservable. These inputs reflect the Company’s assessment of the assumptions that market participants use to value the investment based on the best available information. Level III inputs include prices of quoted securities in markets for which there are few transactions, less public information exists or prices vary among brokered market makers. The types of investments in Level III include non-publicly traded equity, debt, real estate and derivatives. In some instances, the inputs used to value an instrument may fall into multiple levels of the fair-value hierarchy. In such instances, the instrument’s level within the fair-value hierarchy is based on the lowest of the three levels (with Level III being the lowest) that is significant to the fair-value measurement. The Company’s assessment of the significance of an input requires judgment and considers factors specific to the instrument. Transfers of assets into or out of each fair value hierarchy level as a result of changes in the observability of the inputs used in measuring fair value are accounted for as of the beginning of the reporting period. Transfers resulting from a specific event, such as a reorganization or restructuring, are accounted for as of the date of the event that caused the transfer. In the absence of observable market prices, the Company values Level III investments using valuation methodologies applied on a consistent basis. The quarterly valuation process for Level III investments begins with each portfolio company, property or security being valued by the investment and/or valuation teams. With the exception of open-end funds, all unquoted Level III investment values are reviewed and approved by (i) the Company’s valuation officer, who is independent of the investment teams, (ii) a designated investment professional of each strategy and (iii) for a substantial majority of unquoted Level III holdings as measured by market value, a valuation committee of the respective strategy. For open-end funds, unquoted Level III investment values are reviewed and approved by the Company’s valuation officer. For certain investments, the valuation process also includes a review by independent valuation parties, at least annually, to determine whether the fair values determined by management are reasonable. Results of the valuation process are evaluated each quarter, including an assessment of whether the underlying calculations should be adjusted or recalibrated. In connection with this process, the Company periodically evaluates changes in fair-value measurements for reasonableness, considering items such as industry trends, general economic and market conditions, and factors specific to the investment. Certain assets are valued using prices obtained from pricing vendors or brokers. The Company seeks to obtain prices from at least two pricing vendors for the subject or similar securities. In cases where vendor pricing is not reflective of fair value, a secondary vendor is unavailable, or no vendor pricing is available, a comparison value made up of quotes for the subject or similar securities received from broker dealers may be used. These investments may be classified as Level III because the quoted prices may be indicative in nature for securities that are in an inactive market, may be for similar securities, or may require adjustment for investment-specific factors or restrictions. The Company evaluates the prices obtained from brokers or pricing vendors based on available market information, including trading activity of the subject or similar securities, or by performing a comparable security analysis to ensure that fair values are reasonably estimated. The Company also performs back-testing of valuation information obtained from pricing vendors and brokers against actual prices received in transactions. In addition to ongoing monitoring and back-testing, the Company performs due diligence procedures surrounding pricing vendors to understand their methodology and controls to support their use in the valuation process. Fair Value Option The Company has elected the fair value option for certain corporate investments that otherwise would not have reflected unrealized gains and losses in current-period earnings. Such election is irrevocable and is applied on an investment-by-investment basis at initial recognition. Unrealized gains and losses resulting from changes in fair value are reflected as a component of investment income in the condensed consolidated statements of operations. The Company’s accounting for these investments is similar to its accounting for investments held by the consolidated funds at fair value and the valuation methods are consistent with those used to determine the fair value of the consolidated funds’ investments. The Company has elected the fair value option for the financial assets and financial liabilities of its consolidated CLOs. The assets and liabilities of CLOs are primarily reflected within the investments, at fair value and within the debt obligations of CLOs line items in the condensed consolidated statements of financial condition. The Company’s accounting for CLO assets is similar to its accounting for its funds with respect to both carrying investments held by CLOs at fair value and the valuation methods used to determine the fair value of those investments. The fair value of CLO liabilities are measured as the fair value of CLO assets less the sum of (a) the fair value of any beneficial interests held by the Company and (b) the carrying value of any beneficial interests that represent compensation for services. Realized gains or losses and changes in the fair value of CLO assets, respectively, are included in net realized gain on consolidated funds’ investments and net change in unrealized appreciation (depreciation) on consolidated funds’ investments in the condensed consolidated statements of operations. Interest income of CLOs is included in interest and dividend income, and interest expense and other expenses, respectively, are included in interest expense and consolidated fund expenses in the condensed consolidated statements of operations. Changes in the fair value of a CLO’s financial liabilities in accordance with the CLO measurement guidance are included in net change in unrealized appreciation (depreciation) on consolidated funds’ investments in the condensed consolidated statements of operations. Please see notes 7 and 11 for more information. Accounting Policies of Consolidated Funds Investments, at Fair Value The consolidated funds include investment limited partnerships and CLOs that reflect their investments, including majority-owned and controlled investments, at fair value. The Company has retained the specialized investment company accounting guidance under GAAP for investment limited partnerships with respect to consolidated investments and has elected the fair value option for the financial assets of CLOs. Thus, the consolidated investments are reflected in the condensed consolidated statements of financial condition at fair value, with unrealized gains and losses resulting from changes in fair value reflected as a component of net change in unrealized appreciation (depreciation) on consolidated funds’ investments in the condensed consolidated statements of operations. Fair value is the amount 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 (i.e., the exit price). Non-publicly traded debt and equity securities and other securities or instruments for which reliable market quotations are not available are valued by management using valuation methodologies applied on a consistent basis. These securities may initially be valued at the acquisition price as the best indicator of fair value. The Company reviews the significant unobservable inputs, valuations of comparable investments and other similar transactions for investments valued at acquisition price to determine whether another valuation methodology should be utilized. Subsequent valuations will depend on the facts and circumstances known as of the valuation date and the application of valuation methodologies as further described below under “—Non-publicly Traded Equity and Real Estate Investments.” The fair value may also be based on a pending transaction expected to close after the valuation date. Exchange-traded Investments Securities listed on one or more national securities exchanges are valued at their last reported sales price on the date of valuation. If no sale occurred on the valuation date, the security is valued at the mean of the last “bid” and “ask” prices on the valuation date. Securities that are not readily marketable due to legal restrictions that may limit or restrict transferability are generally valued at a discount from quoted market prices. The discount would reflect the amount market participants would require due to the risk relating to the inability to access a public market for the security for the specified period and would vary depending on the nature and duration of the restriction and the perceived risk and volatility of the underlying securities. Securities with longer duration restrictions or higher volatility are generally valued at a higher discount. Such discounts are generally estimated based on put option models or an analysis of market studies. Instances where the Company has applied discounts to quoted prices of restricted listed securities have been infrequent. The impact of such discounts is not material to the Company’s condensed consolidated statements of financial condition and results of operations for all periods presented. Credit-oriented Investments (including Real Estate Loan Portfolios) Investments in corporate and government debt which are not listed or admitted to trading on any securities exchange are valued at the mean of the last bid and ask prices on the valuation date based on quotations supplied by recognized quotation services or by reputable broker-dealers. The market-yield approach is considered in the valuation of non-publicly traded debt securities, utilizing expected future cash flows and discounted using estimated current market rates. Discounted cash-flow calculations may be adjusted to reflect current market conditions and/or the perceived credit risk of the borrower. Consideration is also given to a borrower’s ability to meet principal and interest obligations; this may include an evaluation of collateral and/or the underlying value of the borrower utilizing techniques described below under “—Non-publicly Traded Equity and Real Estate Investments.” Non-publicly Traded Equity and Real Estate Investments The fair value of equity and real estate investments is determined using a cost, market or income approach. The cost approach is based on the current cost of reproducing a real estate investment less deterioration and functional and economic obsolescence. The market approach utilizes valuations of comparable public companies and transactions, and generally seeks to establish the enterprise value of the portfolio company or investment property using a market-multiple methodology. This approach takes into account the financial measure (such as EBITDA, adjusted EBITDA, free cash flow, net operating income, net income, book value or net asset value) believed to be most relevant for the given company or investment property. Consideration also may be given to factors such as acquisition price of the security or investment property, historical and projected operational and financial results for the portfolio company, the strengths and weaknesses of the portfolio company or investment property relative to its comparable companies or properties, industry trends, general economic and market conditions, and others deemed relevant. The income approach is typically a discounted cash-flow method that incorporates expected timing and level of cash flows. It incorporates assumptions in determining growth rates, income and expense projections, discount and capitalization rates, capital structure, terminal values, and other factors. The applicability and weight assigned to market and income approaches are determined based on the availability of reliable projections and comparable companies and transactions. The valuation of securities may be impacted by expectations of investors’ receptiveness to a public offering of the securities, the size of the holding of the securities and any associated control, information with respect to transactions or offers for the securities (including the transaction pursuant to which the investment was made and the elapsed time from the date of the investment to the valuation date), and applicable restrictions on the transferability of the securities. These valuation methodologies involve a significant degree of management judgment. Accordingly, valuations by the Company do not necessarily represent the amounts that eventually may be realized from sales or other dispositions of investments. Fair values may differ from the values that would have been used had a ready market for the investment existed, and the differences could be material to the condensed consolidated financial statements. Recent Accounting Developments In January 2017, the Financial Accounting Standards Board (“FASB”) issued guidance to simplify the accounting for goodwill impairments by eliminating step 2 of the goodwill impairment test. This step currently requires an entity to perform a hypothetical purchase price allocation to derive the implied fair value of goodwill. Under the new guidance, an impairment loss is recognized if the carrying value of a reporting unit exceeds its fair value. The impairment loss would equal the amount of that excess, limited to the total amount of goodwill. All other goodwill impairment guidance remains largely unchanged. Entities will continue to have the option to perform a qualitative assessment to determine if a quantitative impairment test is necessary. The guidance is effective for the Company in the first quarter of 2020 on a prospective basis, with early adoption permitted. The Company expects that adoption of this guidance will not have a material impact on the consolidated financial statements. In August 2016, the FASB issued guidance on the classification of certain cash receipts and payments in the statement of cash flows. The amendments add to or clarify guidance on a number of cash flow issues, including debt prepayment or debt extinguishment costs, contingent consideration payments made after a business combination, distributions received from equity-method investees and beneficial interests in securitization transactions. The Company adopted this guidance in the first quarter of 2018 on a retrospective basis. The impact of adoption was not material to the Company’s consolidated financial statements. In February 2016, the FASB issued guidance that will require a lessee to recognize a lease asset and a lease liability for most of its operating leases. Under current GAAP, operating leases are not recognized by a lessee in its statements of financial position. In general, the new asset and liability will each equal the present value of lease payments. The guidance does not significantly change the recognition, measurement and presentation of expenses and cash flows arising from a lease by a lessee. The Company expects to adopt the guidance in the first quarter of 2019 under the simplified transition method approved by the FASB in March 2018. 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 does not expect that adoption will have a material impact on the consolidated statements of operations because all of the Company’s leases are currently classified as operating leases, which under the guidance will continue to be recognized as expense on a straight-line basis. The adoption, however, will result in a significant gross-up in total assets and total liabilities on the consolidated statements of financial position. The gross-up impact as of June 30, 2018 is estimated to be approximately $129 million , which represents the aggregate discounted amount of the Company’s minimum lease payments under lease obligations as of June 30, 2018. In May 2014, the FASB issued guidance on revenue recognition that superseded most existing revenue recognition guidance, including industry-specific guidance. The guidance outlined a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers, and provides a largely principles-based framework for addressing revenue recognition issues on a comprehensive basis. Under the guidance, revenue is recognized when an entity satisfies a performance obligation by transferring control of a promised good or service to a customer in an amount that reflects the consideration for which the entity expects to be entitled for that good or service. The guidance also requires qualitative and quantitative disclosures about revenue that has been recognized and revenue that is expected to be recognized in the future from existing contracts, significant judgments and changes in those judgments made by management in recognizing revenue, disaggregation of revenue, and information about contract balances. The Company adopted this guidance in the first quarter of 2018 on a modified retrospective basis. The most significant effect of the guidance for the Company relates to the recognition of incentive income. The guidance requires the Company to recognize incentive income when it concludes that it is probable that significant reversals of revenue will not occur in subsequent periods. Under legacy GAAP, the amount of incentive income recognized by the Company was generally limited to the amount not contingent on a future event. Upon adoption, the Company recorded a cumulative-effect increase to unitholders’ capital of $ 48.7 million , net of tax, as of January 1, 2018. This adjustment relates to incentive income that would have met the “probable that significant reversal will not occur” criteria as of that date. In addition, effective January 1, 2018, certain reimbursements received by the Company from the investment funds it manages are reported as revenues on a gross basis with an equal offset to expenses in the consolidated statements of operations. Please see note 4 for more information on revenues.

Asset Acquisitions [Abstract]
ACQUISITIONS	ACQUISITIONS On October 17, 2017, the Company completed a transaction in which it became the new investment adviser to two business development companies (the “BDCs”): Oaktree Specialty Lending Corporation (NASDAQ: OCSL) and Oaktree Strategic Income Corporation (NASDAQ: OCSI). Upon the closing of the transaction (the “BDC acquisition”), the Company paid $ 320.0 million in cash to Fifth Street Management LLC (“FSM”), net of certain transaction-related expenses, for all of FSM’s right, title and interest in specified business records related to FSM’s then-existing investment advisory agreements with each BDC. The transaction was accounted for as an asset acquisition. The net purchase price was $ 319.4 million , consisting of the $ 320.0 million cash payment, net of certain transaction-related expenses and reimbursements received from the seller. Substantially all of the purchase price was allocated to finite-lived contractual rights. While FSM pledged cash and other assets with an estimated fair value of $ 56.2 million to indemnify the Company or the BDCs against potential claims or assessments, the Company determined that the amount of the potential liability associated with these claims could not be reasonably estimated as of the acquisition date so no amounts were recognized in purchase accounting related to the indemnification agreement.

Revenue from Contract with Customer [Abstract]
REVENUES	REVENUES On January 1, 2018, the Company adopted the new revenue recognition standard on a modified retrospective basis. As a result, prior period amounts continue to be reported under historic GAAP. Upon adoption, the Company recorded a cumulative-effect increase to unitholders’ capital as of January 1, 2018 of $ 48.7 million , net of tax. This adjustment relates to incentive income that would have met the “probable that significant reversal will not occur” criteria as of January 1, 2018 under the new revenue standard. Revenue Recognition The Company earns management fees and incentive income from the investment advisory services it provides to its customers. Revenue is recognized when control of the promised services is transferred to customers in an amount that reflects the consideration the Company expects to receive in exchange for those services. The Company typically enters into contracts with investment funds to provide investment management and administrative services. These services are generally capable of being distinct and each is accounted for as separate performance obligations comprised of distinct service periods because the services are performed over time. The Company determined that for accounting purposes the investment funds are generally considered to be the customers with respect to commingled funds, while the individual investors are the customers with respect to separate account and fund-of-one vehicles. The Company receives management fees and/or incentive income with respect to its investment management services, and it is reimbursed by the funds for expenses incurred or paid on behalf of the funds with respect to its investment advisory services and its administrative services. The Company evaluates whether it is the principal (i.e., report as management fees on a gross basis) or agent (i.e., report as management fees on a net basis) with respect to each performance obligation and associated reimbursement arrangements. The Company has elected to apply the variable consideration exemption for its fee arrangements with its customers. Management Fees Management fees are recognized over the period in which the investment management services are performed because customers simultaneously consume and receive benefits that are satisfied over time. The contractual terms of management fees generally vary by fund structure. For most closed-end funds, the management fee rate is applied against committed capital during the fund’s investment period and the lesser of total funded capital or cost basis of assets in the liquidation period. Certain closed-end funds pay management fees during the investment period based on drawn capital or cost basis. Additionally, for closed-end funds that pay management fees based on committed capital, the Company may elect to delay the start of the fund’s investment period and thus its full management fees, in which case it earns management fees based on drawn capital, and in certain cases outstanding borrowings under a fund-level credit facility made in lieu of drawing capital, until the Company elects to start the fund’s investment period. In the case of CLOs, the management fee is based on the aggregate par value of collateral assets and principal cash, as defined in the applicable CLO indentures, and a portion of the management fees is dependent on the sufficiency of the particular vehicle’s cash flow. For open-end and evergreen funds, the management fee is generally based on the NAV of the fund. For the publicly-traded BDCs, the management fee is based on gross assets (including assets acquired with leverage), net of cash. In the case of certain open-end fund accounts, the Company has the potential to earn performance-based fees, typically in reference to a relevant benchmark index or hurdle rate, which are classified as management fees. The Company also earns quarterly incentive fees on the investment income from certain evergreen funds, such as the publicly-traded BDCs and other fund accounts, which are generally recurring in nature and reflected as management fees. The ultimate amount of management fees that will be earned over the life of the contract is subject to a large number and broad range of possible outcomes due to market volatility and other factors outside of the Company’s control. However, the amount of revenue earned in any given period is generally determined at the end of each reporting period and relates to services performed during that period. The impact on management fees as a result of applying the new revenue standard for the three and six months ended June 30, 2018 was an increase of $2.5 million and $6.7 million , respectively. This amount relates to the gross-up of reimbursable costs incurred on behalf of Oaktree funds in which the Company has determined it is the principal. Such costs are presented in compensation and benefits and general and administrative expenses. Incentive Income Incentive income generally represents 20% of each closed-end fund’s profits, subject to the return of contributed capital and a preferred return of typically 8% per annum, and up to 20% of certain evergreen fund’s annual profits, subject to high-water marks or hurdle rates. Incentive income is recognized when it is probable that a significant reversal will not occur. Revenue recognition is typically met (a) for closed-end funds, only after all contributed capital and the preferred return on that capital have been distributed to the fund’s investors, and (b) for certain evergreen funds, at the conclusion of each annual measurement period. Potential incentive income is highly susceptible to market volatility, the judgment and actions of third parties, and other factors outside of the Company’s control. The Company’s experience has demonstrated little predictive value in the amount of potential incentive income ultimately earned due to the highly uncertain nature of returns inherent in the markets and contingencies associated with many realization events. As a result, the amount of incentive income recognized in any given period is generally determined after giving consideration to a number of factors, including whether the fund is in its investment or liquidation period, and the nature and level of risk associated with changes in fair value of the remaining assets in the fund. In general, it would be unlikely that any amount of potential incentive income would be recognized until (a) the uncertainty is resolved or (b) the fund is near final liquidation, assets are under contract for sale or are of low risk of significant fluctuation in fair value, and the assets are significantly in excess of the threshold at which incentive income would be earned. The impact on incentive income as a result of applying the new revenue standard for the three and six months ended June 30, 2018 was a decrease of $0.1 million and $47.0 million , respectively. Incentives received by Oaktree before the revenue recognition criteria have been met are deferred and recorded as a deferred incentive income liability within accounts payable, accrued expenses and other liabilities in the condensed consolidated statements of financial condition. The Company may receive tax distributions related to taxable income allocated by funds, which are treated as an advance of incentive income and subject to the same recognition criteria. Tax distributions are contractually not subject to clawback. The following schedule presents revenues disaggregated by fund structure, each of which is affected by economic factors related to the asset class composition of the holdings and the contractual terms such as the basis for calculating the management fees and investors’ ability to redeem: Three Months Ended June 30, Six Months Ended June 30, 2018 2017 2018 2017 Management Fees Closed-end $ 117,423 $ 126,257 $ 240,810 $ 253,978 Open-end 36,557 40,283 74,109 80,228 Evergreen 24,116 13,488 48,592 26,750 Total $ 178,096 $ 180,028 $ 363,511 $ 360,956 Incentive Income Closed-end $ 31,880 $ 449,708 $ 183,786 $ 558,365 Evergreen 3,307 4,319 3,307 4,319 Total $ 35,187 $ 454,027 $ 187,093 $ 562,684 Contract Balances The Company receives management fees monthly or quarterly in accordance with its contracts with customers. Incentive income is received when the fund makes a distribution. Contract assets relate to the Company’s conditional right to receive payment for its performance completed under the contract. Receivables are recorded when the right to consideration becomes unconditional (i.e., only requires the passage of time). Contract liabilities (i.e., deferred revenues) relate to payments received in advance of performance under the contract. Contract liabilities are recognized as revenues when the Company provides investment management services. The table below sets forth contract balances for the periods indicated: As of June 30, 2018 December 31, 2017 Receivables (1) $ 62,752 $ 98,738 Contract assets (1) 7,935 54,221 Contract liabilities (2) (23,038 ) (25,297 ) (1) The decline in balances was primarily related to payments received, net of accruals. (2) Revenue recognized in the three and six months ended June 30, 2018 from amounts included in the contract liability balance was $3.7 million and $21.6 million , respectively.

VARIABLE INTEREST ENTITIES

VARIABLE INTEREST ENTITIES	6 Months Ended
VARIABLE INTEREST ENTITIES	Jun. 30, 2018
Organization, Consolidation and Presentation of Financial Statements [Abstract]
VARIABLE INTEREST ENTITIES	VARIABLE INTEREST ENTITIES The Company consolidates VIEs for which it is the primary beneficiary. VIEs include funds managed by Oaktree and CLOs for which Oaktree acts as collateral manager. The purpose of these VIEs is to provide investment opportunities for investors in exchange for management fees and, in certain cases, performance-based fees. While the investment strategies of the funds and CLOs differ by product, in general the fundamental risks of the funds and CLOs have similar characteristics, including loss of invested capital and reduction or absence of management and performance-based fees. As general partner or collateral manager, respectively, Oaktree generally considers itself the sponsor of the applicable fund or CLO. The Company does not provide performance guarantees and, other than capital commitments, has no financial obligation to provide funding to VIEs. Consolidated VIEs As of June 30, 2018, the Company consolidated 20 VIEs for which it was the primary beneficiary, including 11 funds managed by Oaktree, eight CLOs for which Oaktree serves as collateral manager, and Oaktree AIF Holdings, Inc., which was formed to hold certain assets for regulatory and other purposes. Two of the consolidated funds, Oaktree Enhanced Income Retention Holdings III, LLC and Oaktree CLO RR Holder, LLC, were formed to satisfy risk retention requirements under Section 15G of the Exchange Act. One of the CLOs had not priced as of June 30, 2018. As of December 31, 2017, the Company consolidated 21 VIEs. As of June 30, 2018, the assets and liabilities of the 19 consolidated VIEs representing funds and CLOs amounted to $5.7 billion and $4.4 billion , respectively. The assets of these consolidated VIEs primarily consisted of investments in debt and equity securities, while their liabilities primarily represented debt obligations issued by CLOs. The assets of these VIEs may be used only to settle obligations of the same VIE. In addition, there is no recourse to the Company for the VIEs’ liabilities. In exchange for managing either the funds’ or CLOs’ collateral, the Company typically earns management fees and may earn performance fees, all of which are eliminated in consolidation. As of June 30, 2018, the Company’s investments in consolidated VIEs had a carrying value of $470.6 million , which represented its maximum risk of loss as of that date. The Company’s investments in CLOs are generally subordinated to other interests in the CLOs and entitle the Company to receive a pro-rata portion of the residual cash flows, if any, from the CLOs. Please see note 11 for more information on CLO debt obligations. Unconsolidated VIEs The Company holds variable interests in certain VIEs in the form of direct equity interests that are not consolidated because it is not the primary beneficiary, inasmuch as its fee arrangements are considered at-market and it does not hold interests in those entities that are considered more than insignificant. The carrying value of the Company’s investments in VIEs that were not consolidated are shown below. Carrying Value as of June 30, 2018 December 31, 2017 Corporate investments $ 926,252 $ 930,699 Due from affiliates 83,472 160,257 Maximum exposure to loss $ 1,009,724 $ 1,090,956

Investments [Abstract]
INVESTMENTS	INVESTMENTS Corporate Investments Corporate investments consist of investments in funds and companies in which the Company does not have a controlling financial interest. Investments for which the Company is deemed to exert significant influence are accounted for under the equity method of accounting and reflect Oaktree’s ownership interest in each fund or company. In the case of investments for which the Company is not deemed to exert significant influence or control, the fair value option of accounting has been elected. Investment income represents the Company’s pro-rata share of income or loss from these funds or companies, or the change in fair value of the investment, as applicable. Oaktree’s general partnership interests are substantially illiquid. While investments in funds reflect each respective fund’s holdings at fair value, equity-method investments in DoubleLine Capital LP and its affiliates (collectively, “DoubleLine”) and other companies are not adjusted to reflect the fair value of the underlying company. The fair value of the underlying investments in Oaktree funds is based on the Company’s assessment, which takes into account expected cash flows, earnings multiples and/or comparisons to similar market transactions, among other factors. Valuation adjustments reflecting consideration of credit quality, concentration risk, sales restrictions and other liquidity factors are integral to valuing these instruments. Corporate investments consisted of the following: As of Corporate Investments June 30, 2018 December 31, 2017 Equity-method investments: Funds $ 925,073 $ 916,559 Companies 25,775 42,294 Other investments, at fair value 60,998 50,778 Total corporate investments $ 1,011,846 $ 1,009,631 The components of investment income are set forth below: Three Months Ended June 30, Six Months Ended June 30, Investment Income 2018 2017 2018 2017 Equity-method investments: Funds $ 25,798 $ 36,562 $ 53,064 $ 69,483 Companies 17,430 18,829 35,568 34,723 Other investments, at fair value 13,695 (6,285 ) 2,854 (4,649 ) Total investment income $ 56,923 $ 49,106 $ 91,486 $ 99,557 Equity-method Investments The Company’s equity-method investments include its investments in Oaktree funds for which it serves as general partner and other third-party funds and companies that are not consolidated but for which the Company is deemed to exert significant influence. The Company’s share of income or loss generated by these investments is recorded within investment income in the condensed consolidated statements of operations. The Company’s equity-method investments in Oaktree funds principally reflect the Company’s general partner interests in those funds, which typically does not exceed 2.5% in each fund. The Oaktree funds are investment companies that follow a specialized basis of accounting established by GAAP. Equity-method investments in companies include the Company’s one-fifth equity stake in DoubleLine. Each reporting period, the Company evaluates each of its equity-method investments to determine if any are considered significant, as defined by the SEC. As of or for the year ended December 31, 2017, no individual equity-method investment met the significance criteria. As a result, separate financial statements were not required for any of the Company’s equity-method investments. Summarized financial information of the Company’s equity-method investments is set forth below.

Net Gains (Losses) From Investment Activities of Consolidated Funds Net gains (losses) from investment activities in the condensed consolidated statements of operations consist primarily of realized and unrealized gains and losses on the consolidated funds’ investments (including foreign-exchange gains and losses attributable to foreign-denominated investments and related activities) and other financial instruments. Unrealized gains or losses result from changes in the fair value of these investments and other financial instruments. Upon disposition of an investment, unrealized gains or losses are reversed and an offsetting realized gain or loss is recognized in the current period.

Fair Value Disclosures [Abstract]
FAIR VALUE	FAIR VALUE Fair Value of Financial Assets and Liabilities The short-term nature of cash and cash-equivalents, receivables and accounts payable causes each of their carrying values to approximate fair value. The fair value of short-term investments included in cash and cash-equivalents is a Level I valuation. The Company’s other financial assets and financial liabilities by fair-value hierarchy level are set forth below. Please see notes 11 and 18 for the fair value of the Company’s outstanding debt obligations and amounts due from/to affiliates, respectively.

Transfers between Level I and Level II positions for the six months ended June 30, 2018 included $ 0.7 million from Level I to Level II due to a decline in trading activity for one credit-oriented security, which was valued using vendor prices. Transfers between Level I and Level II positions for the six months ended June 30, 2017 included $0.4 million from Level I to Level II due to a decline in trading activity for one credit-oriented security, which was valued using broker quotes. Transfers out of Level III are generally attributable to certain investments that experienced a more significant level of market trading activity or completed an initial public offering during the respective period and thus were valued using observable inputs. Transfers into Level III typically reflect either investments that experienced a less significant level of market trading activity during the period or portfolio companies that undertook restructurings or bankruptcy proceedings and thus were valued in the absence of observable inputs. The following table sets forth a summary of the valuation techniques and quantitative information utilized in determining the fair value of the consolidated funds’ Level III investments as of June 30, 2018: Investment Type Fair Value Valuation Technique Significant Unobservable (1)(2) Range Weighted Average (3) Credit-oriented investments: Consumer $ 6,112 Discounted cash flow (4) Discount rate 11% – 24% 15% 13,395 Recent market information (5) Quoted prices Not applicable Not applicable Financials: 101,104 Recent market information (5) Quoted prices Not applicable Not applicable 1,591 Recent transaction price (8) Not applicable Not applicable Not applicable Industrials: 4,045 Discounted cash flow (4) Discount rate 10% – 12% 11% 11,750 Recent market information (5) Quoted prices Not applicable Not applicable Real estate: 2,663 Discounted cash flow (4) Discount rate 12% – 14% 13% 25,774 Recent market information (5) Quoted prices Not applicable Not applicable Other: 13,836 Discounted cash flow (4) Discount rate 8% – 16% 13% 27,195 Recent market information (5) Quoted prices Not applicable Not applicable Equity investments: 2,097 Discounted cash flow (4) Discount rate 10% – 30% 13% 1,529 Market approach (6) Earnings multiple (7) 5x – 11x 7x 52,000 Recent transaction price (8) Not applicable Not applicable Not applicable 894 Recent market information (5) Quoted prices Not applicable Not applicable Total Level III $ 263,985 The following table sets forth a summary of the valuation techniques and quantitative information utilized in determining the fair value of the consolidated funds’ Level III investments as of December 31, 2017: Investment Type Fair Value Valuation Technique Significant Unobservable (1)(2) Range Weighted Average (3) Credit-oriented investments: Financials: $ 53,732 Recent market information (5) Quoted prices Not applicable Not applicable Industrials: 14,563 Discounted cash flow (4) Discount rate 6% – 11% 7% 3,782 Recent market information (5) Quoted prices Not applicable Not applicable Information 5,331 Discounted cash flow (4) Discount rate 11% – 13% 12% 13,965 Recent market information (5) Quoted prices Not applicable Not applicable Real estate: 2,897 Discounted cash flow (4) Discount rate 11% – 13% 12% 22,297 Recent market information (5) Quoted prices Not applicable Not applicable 327 Recent transaction price (8) Not applicable Not applicable Not applicable Other: 15,881 Discounted cash flow (4) Discount rate 8% – 20% 12% 660 Market approach (6) Earnings multiple (7) 8x – 10x 9x 29,452 Recent market information (5) Quoted prices Not applicable Not applicable Equity investments: 378 Market approach (6) Earnings multiple (7) 9x – 11x 10x 1,343 Discounted cash flow (4) Discount rate 11% – 30% 13% 1,707 Recent market information (5) Quoted prices Not applicable Not applicable Real estate investments: Real estate: 121,087 Recent transaction price (8) Not applicable Not applicable Not applicable Total Level III $ 287,402 (1) The discount rate is the significant unobservable input used in the fair-value measurement of performing credit-oriented investments in which the consolidated funds do not have a controlling interest in the underlying issuer, as well as certain equity investments and real estate loan portfolios. An increase (decrease) in the discount rate would result in a lower (higher) fair-value measurement. (2) Multiple of either earnings or underlying assets is the significant unobservable input used in the market approach for the fair-value measurement of distressed credit-oriented investments, credit-oriented investments in which the consolidated funds have a controlling interest in the underlying issuer, equity investments and certain real estate-oriented investments. An increase (decrease) in the multiple would result in a higher (lower) fair-value measurement. (3) The weighted average is based on the fair value of the investments included in the range. (4) A discounted cash-flow method is generally used to value performing credit-oriented investments in which the consolidated funds do not have a controlling interest in the underlying issuer, as well as certain equity investments, real estate-oriented investments and real estate loan portfolios. (5) Certain investments are valued using vendor prices or broker quotes for the subject or similar securities. Generally, investments valued in this manner are classified as Level III because the quoted prices may be indicative in nature for securities that are in an inactive market, may be for similar securities, or may require adjustment for investment-specific factors or restrictions. (6) A market approach is generally used to value distressed investments and investments in which the consolidated funds have a controlling interest in the underlying issuer. (7) Earnings multiples are based on comparable public companies and transactions with comparable companies. The Company typically utilizes multiples of EBITDA; however, in certain cases the Company may use other earnings multiples believed to be most relevant to the investment. The Company typically applies the multiple to trailing twelve-months’ EBITDA. However, in certain cases other earnings measures, such as pro forma EBITDA, may be utilized if deemed to be more relevant. (8) Certain investments are valued based on recent transactions, generally defined as investments purchased or sold within six months of the valuation date. The fair value may also be based on a pending transaction expected to close after the valuation date. A significant amount of judgment may be required when using unobservable inputs, including assessing the accuracy of source data and the results of pricing models. The Company assesses the accuracy and reliability of the sources it uses to develop unobservable inputs. These sources may include third-party vendors that the Company believes are reliable and commonly utilized by other marketplace participants. As described in note 2, other factors beyond the unobservable inputs described above may have a significant impact on investment valuations. During the six months ended June 30, 2018 and 2017, there were no changes in the valuation techniques for Level III securities.

DERIVATIVES AND HEDGING

DERIVATIVES AND HEDGING	Jun. 30, 2018
Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVES AND HEDGING	DERIVATIVES AND HEDGING The Company enters into derivatives as part of its overall risk management strategy or to facilitate its investment management activities. Risks associated with fluctuations in interest rates and foreign-currency exchange rates in the normal course of business are addressed as part of the Company’s overall risk management strategy that may include the use of derivatives to economically hedge or reduce these exposures. From time to time, the Company may enter into (a) foreign-currency option and forward contracts to reduce earnings and cash-flow volatility associated with changes in foreign-currency exchange rates, and (b) interest-rate swaps to manage all or a portion of the interest-rate risk associated with its variable-rate borrowings. As a result of the use of these or other derivative contracts, the Company is exposed to the risk that counterparties will fail to fulfill their contractual obligations. The Company attempts to mitigate this counterparty risk by entering into derivative contracts only with major financial institutions that have investment-grade credit ratings. Counterparty credit risk is evaluated in determining the fair value of derivatives. When the Company enters into a derivative contract, it may elect to designate the derivative as a hedging instrument and apply hedge accounting as part of its overall risk management strategy. In other situations, when a derivative does not qualify for hedge accounting or when the derivative and the hedged item are both recorded in current-period earnings and thus deemed to be economic hedges, hedge accounting is not applied. Freestanding derivatives are financial instruments that the Company enters into as part of its overall risk management strategy but does not utilize hedge accounting. These financial instruments may include foreign-currency exchange contracts, interest-rate swaps and other derivative contracts. There were no derivatives outstanding that were designated as hedging instruments for accounting purposes as of June 30, 2018 and December 31, 2017. The fair value of freestanding derivatives consisted of the following: Assets Liabilities Notional Fair Value Notional Fair Value As of June 30, 2018 Foreign-currency forward contracts $ 86,847 $ 2,082 $ (141,734 ) $ (1,964 ) Cross-currency swap — — (248,311 ) (9,256 ) Total $ 86,847 $ 2,082 $ (390,045 ) $ (11,220 ) As of December 31, 2017 Foreign-currency forward contracts $ 288,451 $ 5,020 $ (242,972 ) $ (13,154 ) Cross-currency swap — — (255,210 ) (7,479 ) Total $ 288,451 $ 5,020 $ (498,182 ) $ (20,633 ) Realized and unrealized gains and losses arising from freestanding derivatives were recorded in the condensed consolidated statements of operations as follows: Three Months Ended June 30, Six Months Ended June 30, 2018 2017 2018 2017 Investment income $ 10,056 $ (8,455 ) $ (2,317 ) $ (9,328 ) General and administrative expense (1) 1,769 (6,268 ) (1,303 ) (8,951 ) Total $ 11,825 $ (14,723 ) $ (3,620 ) $ (18,279 ) (1) To the extent that the Company’s freestanding derivatives are utilized to hedge its foreign-currency exposure to investment income and management fees earned from consolidated funds, the related hedged items are eliminated in consolidation, with the derivative impact (a positive number reflects a reduction in expenses) reflected in consolidated general and administrative expense. Derivatives Held By Consolidated Funds Certain consolidated funds utilize derivatives in their ongoing investment operations. These derivatives primarily consist of foreign-currency forward contracts and options utilized to manage currency risk, interest-rate swaps to hedge interest-rate risk, options and futures used to hedge certain exposures for specific securities, and total-return swaps utilized mainly to obtain exposure to leveraged loans or to participate in foreign markets not readily accessible. The primary risk exposure for options and futures is price, while the primary risk exposure for total-return swaps is credit. None of the derivative instruments are accounted for as a hedging instrument utilizing hedge accounting.

In connection with its derivative activities, the Company generally enters into agreements subject to enforceable master netting arrangements that allow the Company to offset derivative assets and liabilities in the same currency by specific derivative type or, in the event of default by the counterparty, to offset derivative assets and liabilities with the same counterparty. While these derivatives are eligible to be offset in accordance with applicable accounting guidance, the Company has elected to present derivative assets and liabilities based on gross fair value in its condensed consolidated statements of financial condition. The table below sets forth the setoff rights and related arrangements associated with derivatives held by the Company. The “gross amounts not offset in statements of financial condition” columns represent derivatives that management has elected not to offset in the consolidated statements of financial condition even though they are eligible to be offset in accordance with applicable accounting guidance.

Goodwill and Intangible Assets Disclosure [Abstract]
GOODWILL AND INTANGIBLES	GOODWILL AND INTANGIBLES Goodwill represents the excess of cost over the fair value of identifiable net assets of acquired businesses. Goodwill has an indefinite useful life and is not amortized, but instead is tested for impairment annually in the fourth quarter of each fiscal year, or more frequently if events or circumstances indicate that impairment may have occurred. As of June 30, 2018, the Company had determined there was no goodwill impairment. The carrying value of goodwill was $69.3 million as of June 30, 2018 and December 31, 2017. The following table summarizes the carrying value of intangible assets: As of June 30, 2018 December 31, 2017 Contractual rights $ 347,452 $ 347,452 Accumulated amortization (24,689 ) (16,301 ) Intangible assets, net $ 322,763 $ 331,151 Amortization expense associated with the Company’s intangible assets was $4.2 million and $8.4 million for the three and six months ended June 30, 2018, respectively, and $1.0 million and $2.0 million for the three and six months ended June 30, 2017, respectively. Amortization expense is estimated to be $8.4 million for the remaining six months of 2018, $16.8 million per annum for each of the years ending December 31, 2019 and 2020, $15.1 million for 2021, and $12.8 million for 2022.

The credit facility consists of a $150 million term loan and a $500 million revolving credit facility. Borrowings generally bear interest at a spread to either LIBOR or an alternative base rate. Based on the current credit ratings of Oaktree Capital Management, L.P., the interest rate on borrowings is LIBOR plus 1.00% per annum and the commitment fee on the unused portions of the revolving credit facility is 0.10% per annum. The credit agreement contains customary financial covenants and restrictions, including ones regarding a maximum leverage ratio and a minimum required level of assets under management (as defined in the credit agreement, as amended above). As of June 30, 2018, the Company had no outstanding borrowings under the revolving credit facility. As of June 30, 2018, future scheduled principal payments of debt obligations were as follows: Last six months of 2018 $ — 2019 — 2020 — 2021 — 2022 — Thereafter 750,000 Total $ 750,000 The Company was in compliance with all financial maintenance covenants associated with its senior notes and bank credit facility as of June 30, 2018 and December 31, 2017. The fair value of the Company’s debt obligations, which are carried at amortized cost, is a Level III valuation that is estimated based on a discounted cash-flow calculation using estimated rates that would be offered to Oaktree for debt of similar terms and maturities. The fair value of these debt obligations, gross of debt issuance costs, was $733.4 million and $762.7 million as of June 30, 2018 and December 31, 2017, respectively, utilizing an average borrowing rate of 4.2% and 3.6% , respectively. As of June 30, 2018, a 10% increase in the assumed average borrowing rate would lower the estimated fair value to $708.8 million , whereas a 10% decrease would increase the estimated fair value to $759.3 million . In July 2017, the Company agreed to guarantee a $17.5 million standby letter of credit extended to one of the investment funds that it manages, which expired in January 2018. Credit Facilities of the Consolidated Funds Certain consolidated funds may maintain revolving credit facilities that are secured by the assets of the fund or may issue senior variable rate notes to fund investments on a longer term basis, generally up to ten years. The obligations of the consolidated funds are nonrecourse to the Company. The consolidated funds had the following debt obligations outstanding: Outstanding Amount as of Facility Capacity Weighted Average Interest Rate Weighted Average Remaining Maturity (years) Commitment Fee Rate L/C Fee Credit Agreement June 30, 2018 December 31, 2017 Senior variable rate notes $ 870,098 $ 870,098 $ 870,100 3.52% 10.2 N/A N/A Less: Debt issuance costs (6,633 ) (7,697 ) Total debt obligations, net $ 863,465 $ 862,401 As of both June 30, 2018 and December 31, 2017, the consolidated funds had debt obligations with an aggregate outstanding principal balance of $870.1 million . The fair value of the senior variable rate notes is a Level III valuation and aggregated $873.1 million and $872.1 million as of June 30, 2018 and December 31, 2017, respectively, using prices obtained from pricing vendors. Financial instruments that are valued using quoted prices for the security or similar securities are generally classified as Level III because the quoted prices may be indicative in nature for securities that are in an inactive market, may be for similar securities, or may require adjustment for investment-specific factors or restrictions. Debt Obligations of CLOs Debt obligations of CLOs represent amounts due to holders of debt securities issued by the CLOs, as well as term loans of CLOs that had not priced as of period end. Outstanding debt obligations of CLOs were as follows: As of June 30, 2018 As of December 31, 2017 Fair Value (1) Weighted Average Interest Rate Weighted Average Remaining Maturity (years) Fair Value (1) Weighted Average Interest Rate Weighted Average Remaining Maturity (years) Senior secured notes $ 3,209,576 2.57% 9.6 $ 3,107,955 2.18% 10.7 Subordinated note (2) 109,971 N/A 10.3 111,637 N/A 10.8 Total CLO debt obligations $ 3,319,547 $ 3,219,592 (1) The fair value of CLO liabilities was measured as the fair value of CLO assets less the sum of (a) the fair value of any beneficial interests held by the Company and (b) the carrying value of any beneficial interests that represent compensation for services. Please see notes 2 and 7 for more information. (2) The subordinated notes do not have a contractual interest rate; instead, they receive distributions from the excess cash flows generated by the CLO. The debt obligations of CLOs are nonrecourse to the Company and are backed by the investments held by the respective CLO. Assets of one CLO may not be used to satisfy the liabilities of another. As of both June 30, 2018 and December 31, 2017, the fair value of CLO assets was $3.9 billion and consisted of cash, corporate loans, corporate bonds and other securities. As of June 30, 2018, future scheduled principal or par value payments with respect to the debt obligations of CLOs were as follows: Last six months of 2018 $ 195,153 2019 — 2020 — 2021 — 2022 — Thereafter 3,070,701 Total $ 3,265,854

UNITHOLDERS' CAPITAL	Jun. 30, 2018
Stockholders' Equity Note [Abstract]
UNITHOLDERS' CAPITAL	UNITHOLDERS’ CAPITAL Unitholders’ capital reflects the economic interests attributable to Class A unitholders, Series A preferred unitholders, non-controlling interests in consolidated subsidiaries and non-controlling interests in consolidated funds. Non-controlling interests in consolidated subsidiaries represent the portion of unitholders’ capital attributable to the OCGH non-controlling interest and third parties. The OCGH non-controlling interest is determined at the Oaktree Operating Group level, after giving effect to distributions, if any, attributable to the Series A preferred unitholders, based on the proportionate share of Oaktree Operating Group units held by the OCGH unitholders. Certain expenses, such as income taxes and related administrative expenses of Oaktree Capital Group, LLC and its Intermediate Holding Companies, are solely attributable to the Class A unitholders. As of June 30, 2018 and December 31, 2017, respectively, OCGH units represented 86,007,356 of the total 157,182,329 Oaktree Operating Group units and 90,975,687 of the total 156,285,913 Oaktree Operating Group units. Based on total allocable Oaktree Operating Group capital of $1,879,618 and $1,912,517 as of June 30, 2018 and December 31, 2017, respectively, the OCGH non-controlling interest was $1,028,496 and $1,113,314 . As of June 30, 2018 and December 31, 2017, non-controlling interests attributable to third parties was $6,757 and $7,923 , respectively. Class A Unit Issuance On February 12, 2018, the Company issued and sold 5,000,000 Class A units in a public offering, resulting in $ 219.5 million in net proceeds to the Company. The Company did not retain any proceeds from the sale of Class A units in this offering. The proceeds were used to acquire interests in the Company’s business from certain of the Company’s directors, employees and other investors, including certain senior executives and other members of the Company’s senior management. Series A Preferred Unit Issuance On May 17, 2018, the Company issued 7,200,000 6.625% Series A preferred units representing limited liability company interests with a liquidation preference of $25.00 per unit. The issuance resulted in $173.7 million in net proceeds to the Company. The Company intends to use the net proceeds from the sale of the Series A preferred units for general corporate purposes, including to fund investments. Distributions on the Series A preferred units, when and if declared by the board of directors of Oaktree, will be paid quarterly on March 15, June 15, September 15 and December 15 of each year, beginning on September 15, 2018. Distributions on the Series A preferred units are non-cumulative. Unless distributions have been declared and paid or declared and set apart for payment on the Series A preferred units for a quarterly distribution period, during the remainder of that distribution period the Company may not repurchase any common units or any other units that are junior in rank, as to the payment of distributions, to the Series A preferred units and the Company may not declare or pay or set apart payment for distributions on any common units or junior units for the remainder of that distribution period, other than certain Permitted Distributions (as defined in the unit designation related to the Series A preferred units (the “Series A Preferred Unit Designation”)). These restrictions are not applicable during the initial distribution period, which is the period from the original issue date to, but excluding, September 15, 2018. The Company may redeem, at its option, out of funds legally available, the Series A preferred units, in whole or in part, at any time on or after June 15, 2023 at a price of $25.00 per Series A preferred unit plus declared and unpaid distributions to, but excluding, the redemption date, without payment of any undeclared distributions. Holders of the Series A preferred units have no right to require the redemption of the Series A preferred units. If a Change of Control Event (as defined in the Series A Preferred Unit Designation) occurs prior to June 15, 2023, the Company may, at its option, out of funds legally available, redeem the Series A preferred units, in whole but not in part, upon at least 30 days’ notice, within 60 days of the occurrence of such Change of Control Event, at a price of $25.25 per Series A preferred unit, plus declared and unpaid distributions to, but excluding, the redemption date, without payment of any undeclared distributions. If a Tax Redemption Event or Rating Agency Event (each, as defined in the Series A Preferred Unit Designation) occurs prior to June 15, 2023, the Company may, at its option, out of funds legally available, redeem the Series A preferred units, in whole but not in part, upon at least 30 days’ notice, within 60 days of the occurrence of such Tax Redemption Event or Rating Agency Event, at a price of $25.50 per Series A preferred unit, plus declared and unpaid distributions to, but excluding, the redemption date, without payment of any undeclared distributions. The Series A preferred units are not convertible into Class A units or any other class or series of the Company’s interests or any other security. Holders of the Series A preferred units do not have any of the voting rights given to holders of our Class A units, except that holders of the Series A preferred units are entitled to certain voting rights under certain conditions.

EARNINGS PER UNIT	EARNINGS PER UNIT The computation of net income per Class A unit is set forth below: Three Months Ended June 30, Six Months Ended June 30, 2018 2017 2018 2017 Net income per Class A unit (basic and diluted): (in thousands, except per unit amounts) Net income attributable to OCG Class A unitholders $ 31,121 $ 117,324 $ 83,853 $ 172,239 Weighted average number of Class A units outstanding (basic and diluted) 71,177 64,193 69,556 63,611 Basic and diluted net income per Class A unit $ 0.44 $ 1.83 $ 1.21 $ 2.71 OCGH units may be exchanged on a one -for- one basis into Class A units, subject to certain restrictions. As of June 30, 2018, there were 86,007,356 OCGH units outstanding, which are vested or will vest through February 15, 2028, that ultimately may be exchanged into 86,007,356 Class A units. The exchange of these units would proportionally increase the Company’s interest in the Oaktree Operating Group. However, as the restrictions set forth in the exchange agreement were in place at the end of each respective reporting period, those units were not included in the computation of diluted earnings per unit for the three and six months ended June 30, 2018 and 2017. A deferred equity unit represents a special unit award that, when vested, will be settled with an unvested OCGH unit on a one -for- one basis. The number of deferred equity units that will vest is based on the achievement of certain performance targets through June 2021. Once a performance target has been met, the applicable number of OCGH units will be issued and begin to vest over 4.0 years. The holder of a deferred equity unit is not entitled to any distributions until the issuance of an OCGH unit in settlement of a deferred equity unit. As of June 30, 2018, no OCGH units were considered issuable under the terms of the arrangement; consequently, no contingently issuable units were included in the computation of diluted earnings per unit for the three and six months ended June 30, 2018. Please see note 15 for more information. Certain compensation arrangements include performance-based awards that could result in the issuance of up to 340,000 OCGH units in total, which would vest over periods of four to ten years from date of issuance. As of June 30, 2018, no OCGH units were considered issuable under the terms of these arrangements; consequently, no contingently issuable units were included in the computation of diluted earnings per unit for the three and six months ended June 30, 2018. The Company had a contingent consideration liability that was payable in cash and fully-vested OCGH units. In May 2018, the contingent consideration arrangement was modified in respect of certain performance targets and payment terms. The new arrangement provides for contingent consideration payable in cash and Class A units. No Class A units or OCGH units were considered issuable under the terms of the arrangement for the three and six months ended June 30, 2018 and 2017; consequently no contingently issuable units were included in the computation of diluted earnings per unit for for such periods. Please see note 17 for more information.

EQUITY-BASED COMPENSATION	Jun. 30, 2018
Share-based Compensation [Abstract]
EQUITY-BASED COMPENSATION	EQUITY-BASED COMPENSATION Class A and OCGH Unit Awards During the six months ended June 30, 2018, the Company granted 1,150,196 Class A units and 113,801 restricted OCGH units to its employees and directors, subject to annual vesting over a weighted average period of approximately 4.4 years . The grant date fair value of OCGH units awarded during the six months ended June 30, 2018 was determined by applying a 20% discount to the Class A unit trading price on the New York Stock Exchange as of the grant date. With respect to forfeitures, the Company has made an accounting policy election to account for forfeitures when they occur. Accordingly, no forfeitures have been assumed in the calculation of compensation expense. As of June 30, 2018, the Company expected to recognize compensation expense on its unvested Class A and OCGH unit awards of $163.5 million over a weighted average period of 4.0 years. A summary of the status of the Company’s unvested Class A and OCGH unit awards and changes for the period presented are set forth below (actual dollars per unit): Class A Units OCGH Units (1) Number of Units Weighted Average Grant Date Fair Value Number of Units Weighted Average Grant Date Fair Value Balance, December 31, 2017 2,556,316 $ 44.05 2,158,835 $ 39.79 Granted 1,150,196 39.60 113,801 31.68 Vested (863,389 ) 42.53 (282,028 ) 37.61 Forfeited (68,915 ) 39.81 — — Balance, June 30, 2018 2,774,208 $ 42.78 1,990,608 $ 39.63 (1) Excludes certain performance-based awards that could result in the issuance of up to 340,000 OCGH units, which would vest over periods of four to ten years from date of issuance. Though no units have been issued to date under these arrangements, as of June 30, 2018 the Company expected to recognize compensation expense on 120,000 unvested OCGH performance awards of $3.6 million over a weighted average period of 4.7 years under applicable accounting rules. Equity Value Units OCGH equity value units (“EVUs”) represent special limited partnership units in OCGH that entitle the holder the right to receive special distributions that will be settled in OCGH units, based on value created during a specified period in excess of a fixed “Base Value.” The value created will be measured on a per unit basis, based on the appreciation of the Class A units and certain components of quarterly distributions with respect to OCGH units over the period beginning on January 1, 2015 and ending on each of December 31, 2019, December 31, 2020 and December 31, 2021, with one-third of the EVUs recapitalizing on each such date. EVUs also give the holder the right, subject to service vesting and Oaktree performance relative to the accreting Base Value, to receive certain quarterly distributions from OCGH. EVUs do not entitle the holder to any voting rights. The value received under the EVUs will be reduced by (i) distributions received by the holder on 225,000 OCGH units granted to the holder on April 26, 2017, (ii) the value of the portion of profit sharing payments received by the holder attributable to the net incentive income received from certain funds, and (iii) the full value of the OCGH units granted to the holder on April 26, 2017. To the extent that the reduction relates to the value of any such OCGH units that are unvested at the time of the reduction, such OCGH units will vest at that time. Certain EVUs provide the holder with liquidity rights in respect of the special distributions, if any, that will be settled in OCGH units. The Company accounts for EVUs with liquidity rights as liability-classified awards. As of June 30, 2018, there were 1,000,000 equity-classified EVUs and 1,000,000 liability-classified EVUs outstanding. As of June 30, 2018, the Company expected to recognize $2.2 million of compensation expense on its unvested EVUs over the next 1.5 years . Equity-classified EVUs that require future service are expensed on a straight-line basis over the requisite service period. Liability-classified EVUs are remeasured at the end of each quarter. The fair value of EVUs was determined using a Monte Carlo simulation model. The fair value is affected by the Class A unit trading price and assumptions regarding certain complex and subjective variables, including the expected Class A unit trading price volatility, distributions and exercise timing, and the risk-free interest rate. Deferred Equity Units A deferred equity unit represents a special unit award that, when vested, will be settled with an unvested OCGH unit on a one -for- one basis. The number of deferred equity units that will vest is based on the achievement of certain performance targets through June 2021. Once a performance target has been met, the applicable number of OCGH units will be issued and begin to vest over 4.0 years. The holder of a deferred equity unit is not entitled to any distributions until settled by the issuance of an OCGH unit. As of June 30, 2018, there were 250,000 deferred equity units outstanding, all of which were granted in the second quarter of 2017. As of June 30, 2018, the Company expected to recognize $2.5 million of compensation expense on its unvested deferred equity units over a weighted average period of approximately 5.5 years. The fair value of the deferred equity units was determined at the grant date based on the then-prevailing Class A unit trading price and reflected a 20% lack-of-marketability discount for the OCGH units that will be issued upon vesting.

INCOME TAXES AND RELATED PAYMEN

INCOME TAXES AND RELATED PAYMENTS	6 Months Ended
INCOME TAXES AND RELATED PAYMENTS	Jun. 30, 2018
Income Tax Disclosure [Abstract]
INCOME TAXES AND RELATED PAYMENTS	INCOME TAXES AND RELATED PAYMENTS Oaktree is a publicly traded partnership and Oaktree Holdings, Inc. and Oaktree AIF Holdings, Inc., two of its Intermediate Holding Companies, are wholly-owned corporate subsidiaries. Income earned by these corporate subsidiaries is subject to U.S. federal and state income taxation and taxed at prevailing rates. Income earned by non-corporate subsidiaries is not subject to U.S. federal corporate income tax and is allocated to the Oaktree Operating Group’s unitholders. The Company’s effective tax rate is dependent on many factors, including the estimated nature of many amounts and the mix of revenues and expenses between the subsidiaries that are or are not subject to income tax; consequently, from period to period the effective tax rate is subject to significant variation. The Company’s effective tax rate used for interim periods is based on the estimated full-year income tax rate. Certain future items that cannot be reliably estimated, such as incentive income, are excluded from the estimated annual effective tax rate. The tax expense or benefit stemming from these items is recognized in the same period as the underlying income or expense. Tax authorities currently are examining certain income tax returns of Oaktree, with certain of these examinations at an advanced stage. Over the next four quarters ending June 30, 2019, the Company believes that it is reasonably possible that one outcome of these examinations and expiring statutes of limitation on other items may be the release of up to approximately $5.2 million of previously accrued Operating Group income taxes. The Company believes that it has adequately provided for any reasonably foreseeable outcomes related to its tax examinations and that any settlements related thereto will not have a material adverse effect on the Company’s consolidated financial statements; however, there can be no assurances as to the ultimate outcomes. Tax Legislation On December 22, 2017, the Tax Cuts and Jobs Act (the “Tax Act”) was enacted. The Tax Act reduced the corporate income tax rate from 35% to 21%, and included significant changes to other domestic and international corporate income tax provisions. The rate change resulted in a net reduction to net income attributable to Oaktree Capital Group, LLC of $ 33.2 million in the fourth quarter of 2017. The SEC Staff issued Staff Accounting Bulletin No. 118 in December 2017, which allows a financial statement issuer that does not have all necessary information to fully account for the income tax effect of the Tax Act to record a provisional amount in its financial statements that may be subject to adjustment during a subsequent measurement period. As of June 30, 2018, no adjustments have been made to the above provisional amounts. The Company will continue to evaluate the impact of the Tax Act with respect to certain international provisions as well as provisions that have been identified as requiring additional technical guidance. The Company expects to complete its evaluation of the provisional amounts during the second half of 2018 as technical guidance is released and as it completes its 2017 federal and state income tax returns. Exchange Agreement and Tax Receivable Agreement Subject to certain restrictions and the approval of the Company’s board of directors, each holder of OCGH units has the right to exchange his or her vested units for, at the option of the Company’s board of directors, Class A units, an equivalent amount of cash based on then-prevailing market prices and/or other consideration of equal value. Certain of the Oaktree Operating Group entities made an election under Section 754 of the U.S. Internal Revenue Code, as amended, which may result in an adjustment to the tax basis of the assets owned by the Oaktree Operating Group at the time of an exchange. These exchanges may result in increases in tax deductions and tax basis that would reduce the amount of tax that Oaktree Holdings, Inc. and Oaktree AIF Holdings, Inc. would otherwise be required to pay in the future. Oaktree Holdings, Inc. and Oaktree AIF Holdings, Inc. have entered into a tax receivable agreement with OCGH unitholders that, as amended, provides for the payment to an exchanging or selling OCGH unitholder of 85% of the amount of cash savings, if any, in U.S. federal, state, local and foreign income taxes that they actually realize (or are deemed to realize in the case of an early termination payment by Oaktree Holdings, Inc. or Oaktree AIF Holdings, Inc., or a change of control) as a result of an increase in the tax basis of the assets owned by the Oaktree Operating Group. When an exchange of OCGH units results in an increase to the tax basis of the assets owned by the Oaktree Operating Group, a deferred tax asset and an associated liability for payments to OCGH unitholders under the tax receivable agreement are recorded, subject to realizability considerations. The establishment of a deferred tax asset increases additional paid-in capital because the transactions are between Oaktree and its unitholders. Assuming no further material changes in the relevant tax law and that the Company earns sufficient taxable income to realize the full tax benefit of the increased amortization of the assets, the expected estimated future payments to OCGH unitholders under the tax receivable agreement, as of June 30, 2018, are set forth below: Transaction Total Future Payments Payments Through Fiscal Year 2007 Private Offering $ 17,339 2029 Initial public offering 36,767 2034 May 2013 Offering 51,122 2035 March 2014 Offering 38,557 2036 March 2015 Offering 32,498 2037 February 2018 Offering 34,288 2040 Total $ 210,571 Future estimated payments to OCGH unitholders under the tax receivable agreement are subject to increase in the event of additional exchanges of OCGH units. No amounts were paid under the tax receivable agreement during the six months ended June 30, 2018.

COMMITMENTS AND CONTINGENCIES	Jun. 30, 2018
Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES In the normal course of business, Oaktree enters into contracts that contain certain representations, warranties and indemnifications. The Company’s exposure under these arrangements would involve future claims that have not yet been asserted. Inasmuch as no such claims currently exist or are expected to arise, the Company has not accrued any liability in connection with these indemnifications. Legal Actions Oaktree, its affiliates, investment professionals, and portfolio companies are routinely involved in litigation and other legal actions in the ordinary course of their business and investing activities. In addition, Oaktree is subject to the authority of a number of U.S. and non-U.S. regulators, including the SEC and the Financial Industry Regulatory Authority, and those authorities periodically conduct examinations of Oaktree and make other inquiries that may result in the commencement of regulatory proceedings against Oaktree and its personnel. Oaktree is currently not subject to any pending actions or regulatory proceedings that either individually or in the aggregate are expected to have a material impact on its consolidated financial statements. Incentive Income In addition to the incentive income recognized by the Company, certain of its funds have amounts recorded as potentially allocable to the Company as its share of potential future incentive income, based on each fund’s net asset value. Inasmuch as this incentive income is contingent upon future investment activity and other factors, it is not recognized by the Company as revenue until it is probable that a significant reversal will not occur. As of June 30, 2018 and December 31, 2017, respectively, the aggregate of such amounts recorded at the fund level in excess of incentive income recognized by the Company was $1,854,610 and $1,918,952 , for which related direct incentive income compensation expense was estimated to be $961,874 and $1,000,232 . Contingent Liabilities The Company had a contingent consideration obligation of up to $60.0 million related to the Highstar acquisition that was payable in cash and fully-vested OCGH units. The amount of contingent consideration was based on the achievement of certain performance targets over a period of up to seven years from the acquisition date of August 2014. In May 2018, the contingent consideration arrangement was modified in respect of certain performance targets and payment terms. The new arrangement provides for contingent consideration of up to $36.1 million , payable in cash and Class A units. The modification resulted in a $7.1 million reduction in the contingent consideration liability. As of June 30, 2018 and December 31, 2017, respectively, the fair value of the contingent liability was $9.1 million and $18.8 million . Changes in this liability resulted in income of $7.1 million and $9.6 million for the three and six months ended June 30, 2018, respectively, and income of $0.1 million and expense of $0.5 million for the three and six months ended June 30, 2017, respectively. The fair value of the contingent consideration liability is a Level III valuation, which uses a discounted cash-flow analysis based on a probability-weighted average estimate of certain performance targets, including fundraising and revenue levels. The assumptions used in the analysis are inherently subjective, and thus the ultimate amount of the contingent consideration liability may differ materially from the most recent estimate. The contingent consideration liability is included in accounts payable, accrued expenses and other liabilities in the condensed consolidated statements of financial condition. Changes in the liability are recorded in general and administrative expense in the condensed consolidated statements of operations. In connection with the October 2017 BDC acquisition, FSM pledged assets with an estimated fair value of $ 56.2 million to indemnify the Company or the BDCs against any claims or assessments arising from the period during which it managed the BDCs. Please see note 3 for more information. Commitments to Funds As of June 30, 2018 and December 31, 2017, the Company, generally in its capacity as general partner, had undrawn capital commitments of $410.5 million and $429.1 million , respectively, including commitments to both unconsolidated and consolidated funds. Investment Commitments of the Consolidated Funds Certain of the consolidated funds are parties to credit arrangements that provide for the issuance of letters of credit and/or revolving loans, which may require the particular fund to extend loans to investee companies. The consolidated funds use the same investment criteria in making these commitments as they do for investments that are included in the condensed consolidated statements of financial condition. The unfunded liability associated with these credit arrangements is equal to the amount by which the contractual loan commitment exceeds the sum of funded debt and cash held in escrow, if any. As of June 30, 2018 and December 31, 2017, the consolidated funds had potential aggregate commitments of $10.5 million and $6.0 million , respectively. These commitments are expected to be funded by the funds’ cash balances, proceeds from asset sales or drawdowns against existing capital commitments. A consolidated fund may agree to guarantee the repayment obligations of certain investee companies. As of June 30, 2018 and December 31, 2017, there were no guaranteed amounts under such arrangements. Certain consolidated funds are investment companies that are required to disclose financial support provided or contractually required to be provided to any of their portfolio companies. During the six months ended June 30, 2018, the consolidated funds did not provide any financial support to portfolio companies.

RELATED-PARTY TRANSACTIONS	Jun. 30, 2018
Related Party Transactions [Abstract]
RELATED-PARTY TRANSACTIONS	RELATED-PARTY TRANSACTIONS The Company considers its senior executives, employees and unconsolidated Oaktree funds to be affiliates (as defined in the FASB ASC Master Glossary). Amounts due from and to affiliates are set forth below. The fair value of amounts due from and to affiliates is a Level III valuation and was valued based on a discounted cash-flow analysis. The carrying value of amounts due from affiliates approximated fair value due to their short-term nature or because their average interest rate, which ranged from 2.0% to 3.0% , approximated the Company’s cost of debt. The fair value of amounts due to affiliates approximated $110,931 and $93,772 as of June 30, 2018 and December 31, 2017, respectively, based on a discount rate of 10.0% . As of June 30, 2018 December 31, 2017 Due from affiliates: Loans $ 4,134 $ 9,239 Amounts due from unconsolidated funds 70,116 57,155 Management fees and incentive income due from unconsolidated funds 70,687 152,959 Payments made on behalf of unconsolidated entities 3,468 3,784 Non-interest bearing advances made to certain non-controlling interest holders and employees — 87 Total due from affiliates $ 148,405 $ 223,224 Due to affiliates: Due to OCGH unitholders in connection with the tax receivable agreement (please see note 16) $ 210,571 $ 176,283 Amounts due to senior executives, certain non-controlling interest holders and employees 1,100 1,590 Total due to affiliates $ 211,671 $ 177,873 Loans Loans primarily consist of interest-bearing loans made to certain non-controlling interest holders, primarily certain employees, to meet tax obligations related to vesting of equity awards. The loans, which are generally recourse to the borrower or secured by vested equity and other collateral, typically bear interest at the Company’s cost of debt and generated interest income of $62 and $171 for the three and six months ended June 30, 2018, respectively, and $124 and $275 for the three and six months ended June 30, 2017, respectively. Due From Oaktree Funds and Portfolio Companies In the normal course of business, the Company advances certain expenses on behalf of Oaktree funds. Amounts advanced on behalf of consolidated funds are eliminated in consolidation. Certain expenses paid by the Company, which typically are employee travel and other costs associated with particular portfolio company holdings, are reimbursed to the Company by the portfolio companies. Revenues Earned From Oaktree Funds Management fees and incentive income earned from unconsolidated Oaktree funds totaled $189.5 million and $501.6 million for the three and six months ended June 30, 2018, respectively, and $604.6 million and $864.9 million for the three and six months ended June 30, 2017, respectively. Other Investment Transactions The Company’s senior executives, directors and senior professionals are permitted to invest their own capital (or the capital of family trusts or other estate planning vehicles they control) in Oaktree funds, for which they pay the particular fund’s full management fee but not its incentive allocation. To facilitate the funding of capital calls by funds in which employees are invested, the Company periodically advances on a short-term basis the capital calls on certain employees’ behalf. These advances are reimbursed generally toward the end of the calendar quarter in which the capital calls occurred. Amounts advanced by the Company are included within “non-interest bearing advances made to certain non-controlling interest holders and employees” in the above table. Aircraft Services The Company owns an aircraft for business purposes. Howard Marks, the Company’s co-chairman, may use this aircraft for personal travel and will reimburse the Company to the extent his use of the aircraft for personal travel exceeds a certain threshold pursuant to a Company policy adopted as of January 1, 2017. The Company also provides certain senior executives a personal travel allowance for private aircraft usage up to a certain threshold pursuant to the same Company policy. Additionally, the Company occasionally makes use of an aircraft owned by one of its senior executives for business purposes at a price to the Company that is based on market rates. Special Allocations Certain senior executives receive special allocations based on a percentage of profits of the Oaktree Operating Group. These special allocations, which are recorded as compensation expense, are made on a current basis for so long as they remain senior executives of the Company, with limited exceptions.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	Jun. 30, 2018
Accounting Policies [Abstract]
Consolidation	Consolidation The Company consolidates entities in which it has a direct or indirect controlling financial interest based on either a variable interest model or voting interest model. A limited partnership or similar entity is a variable interest entity (“VIE”) if the unaffiliated limited partners do not have substantive kick-out or participating rights. Most of the Oaktree funds are VIEs because they have not granted unaffiliated limited partners substantive kick-out or participating rights. The Company consolidates those VIEs in which it is the primary beneficiary. An entity is deemed to be the primary beneficiary if it holds a controlling financial interest. A controlling financial interest is defined as (a) the power to direct the activities of a VIE that most significantly impact the entity’s economic performance and (b) the obligation to absorb losses of the entity or the right to receive benefits from the entity that could potentially be significant to the VIE. The consolidation guidance requires an analysis to determine (a) whether an entity in which the Company holds a variable interest is a VIE and (b) whether the Company’s involvement, through holding interests directly or indirectly in the entity or contractually through other variable interests (e.g., management and performance-based fees), would give it a controlling financial interest. A decision maker’s fee arrangement is not considered a variable interest if (a) it is compensation for services provided, commensurate with the level of effort required to provide those services, and part of a compensation arrangement that includes only terms, conditions or amounts that are customarily present in arrangements for similar services negotiated at arm’s length (“at-market”), and (b) the decision maker does not hold any other variable interests that absorb more than an insignificant amount of the potential VIE’s expected residual returns. The Company determines whether it is the primary beneficiary of a VIE at the time it becomes involved with a VIE and reconsiders that conclusion at each reporting date. In evaluating whether the Company is the primary beneficiary, the Company evaluates its economic interests in the entity held either directly by the Company or indirectly through related parties. The consolidation analysis can generally be performed qualitatively; however, if it is not readily apparent that the Company is not the primary beneficiary, a quantitative analysis may also be performed. Investments and redemptions (either by the Company, affiliates of the Company or third parties) or amendments to the governing documents of the respective Oaktree funds could affect an entity’s status as a VIE or the determination of the primary beneficiary. The Company does not consolidate most of the Oaktree funds because it is not the primary beneficiary of those funds due to the fact that its fee arrangements are considered at-market and thus not deemed to be variable interests, and it does not hold any other interests in those funds that are considered to be more than insignificant. Please see note 5 for more information regarding both consolidated and unconsolidated VIEs. For entities that are not VIEs, consolidation is evaluated through a majority voting interest model. “Consolidated funds” refers to Oaktree-managed funds and CLOs that the Company is required to consolidate. When funds or CLOs are consolidated, the Company reflects the assets, liabilities, revenues, expenses and cash flows of the funds or CLOs on a gross basis, and the majority of the economic interests in those funds or CLOs, which are held by third-party investors, are reflected as non-controlling interests in consolidated funds or debt obligations of CLOs in the condensed consolidated financial statements. All of the revenues earned by the Company as investment manager of the consolidated funds are eliminated in consolidation. However, because the eliminated amounts are earned from and funded by third-party investors, the consolidation of a fund does not impact net income or loss attributable to the Company. Certain entities in which the Company has the ability to exert significant influence, including unconsolidated Oaktree funds for which the Company acts as general partner, are accounted for under the equity method of accounting.
Non-controlling Interests in Consolidated Funds and Subsidiaries	Non-controlling Redeemable Interests in Consolidated Funds The Company records non-controlling interests to reflect the economic interests of the unaffiliated limited partners. These interests are presented as non-controlling redeemable interests in consolidated funds within the condensed consolidated statements of financial condition, outside of the permanent capital section. Limited partners in open-end and evergreen funds generally have the right to withdraw their capital, subject to the terms of the respective limited partnership agreements, over periods ranging from one month to three years . While limited partners in consolidated closed-end funds generally have not been granted redemption rights, these limited partners do have withdrawal or redemption rights in certain limited circumstances that are beyond the control of the Company, such as instances in which retaining the limited partnership interest could cause the limited partner to violate a law, regulation or rule. The allocation of net income or loss to non-controlling redeemable interests in consolidated funds is based on the relative ownership interests of the unaffiliated limited partners after the consideration of contractual arrangements that govern allocations of income or loss. At the consolidated level, potential incentives are allocated to non-controlling redeemable interests in consolidated funds until such incentives become allocable to the Company under the substantive contractual terms of the limited partnership agreements of the funds. Non-controlling Interests in Consolidated Funds Non-controlling interests in consolidated funds represent the equity interests held by third-party investors in CLOs that had not yet priced as of the respective period end. All non-controlling interests in those CLOs are attributed a share of income or loss arising from the respective CLO based on the relative ownership interests of third-party investors after consideration of contractual arrangements that govern allocations of income or loss. Investors in those CLOs are generally unable to redeem their interests until the respective CLO liquidates, is called or otherwise terminates. Non-controlling Interests in Consolidated Subsidiaries Non-controlling interests in consolidated subsidiaries reflect the portion of unitholders’ capital attributable to OCGH unitholders (“OCGH non-controlling interest”) and third parties. All non-controlling interests in consolidated subsidiaries are attributed a share of income or loss in the respective consolidated subsidiary based on the relative economic interests of the OCGH unitholders or third parties after consideration of contractual arrangements that govern allocations of income or loss. Please see note 13 for more information.
Acquisitions	Acquisitions The Company accounts for business combinations using the acquisition method of accounting, which requires the use of estimates and judgment to measure the fair value of identifiable tangible and intangible assets acquired, liabilities assumed, and non-controlling interests in the acquiree as of the acquisition date. Contingent consideration that is determined to be part of the business combination is recognized at fair value as of the acquisition date and is included in the purchase price. Transaction costs are expensed as incurred. Transactions that do not meet the definition of a business are accounted for as asset acquisitions. The cost of an asset acquisition is allocated to the individual assets acquired and liabilities assumed on a relative fair value basis. Transaction costs are included in the cost of the acquisition and no goodwill is recognized.
Goodwill and Intangibles	Goodwill and Intangibles Goodwill represents the excess of cost over the fair value of identifiable net assets of acquired businesses. Goodwill has an indefinite useful life and is not amortized, but instead is tested for impairment annually in the fourth quarter of each fiscal year, or more frequently when events or circumstances indicate that impairment may have occurred. The Company’s acquired identifiable intangible assets primarily relate to contractual rights to earn future management fees and incentive income. Finite-lived intangible assets are amortized over their estimated useful lives, which range from seven to 25 years, and are reviewed for impairment whenever events or circumstances indicate that the carrying amount of the asset may not be recoverable.
Fair Value of Financial Instruments and Fair Value Option	Fair Value of Financial Instruments GAAP establishes a hierarchical disclosure framework that prioritizes the inputs used in measuring financial instruments at fair value into three levels based on their market observability. Market price observability is affected by a number of factors, such as the type of instrument and the characteristics specific to the instrument. Financial instruments with readily available quoted prices from an active market or for which fair value can be measured based on actively quoted prices generally will have a higher degree of market price observability and a lesser degree of judgment inherent in measuring fair value. Financial assets and liabilities measured and reported at fair value are classified as follows: • Level I – Quoted unadjusted prices for identical instruments in active markets to which the Company has access at the date of measurement. The types of investments in Level I include exchange-traded equities, debt and derivatives with quoted prices. • Level II – Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs are directly or indirectly observable. Level II inputs include interest rates, yield curves, volatilities, prepayment risks, loss severities, credit risks and default rates. The types of investments in Level II generally include corporate bonds and loans, government and agency securities, less liquid and restricted equity investments, over-the-counter traded derivatives, debt obligations of consolidated CLOs, and other investments where the fair value is based on observable inputs. • Level III – Valuations for which one or more significant inputs are unobservable. These inputs reflect the Company’s assessment of the assumptions that market participants use to value the investment based on the best available information. Level III inputs include prices of quoted securities in markets for which there are few transactions, less public information exists or prices vary among brokered market makers. The types of investments in Level III include non-publicly traded equity, debt, real estate and derivatives. In some instances, the inputs used to value an instrument may fall into multiple levels of the fair-value hierarchy. In such instances, the instrument’s level within the fair-value hierarchy is based on the lowest of the three levels (with Level III being the lowest) that is significant to the fair-value measurement. The Company’s assessment of the significance of an input requires judgment and considers factors specific to the instrument. Transfers of assets into or out of each fair value hierarchy level as a result of changes in the observability of the inputs used in measuring fair value are accounted for as of the beginning of the reporting period. Transfers resulting from a specific event, such as a reorganization or restructuring, are accounted for as of the date of the event that caused the transfer. In the absence of observable market prices, the Company values Level III investments using valuation methodologies applied on a consistent basis. The quarterly valuation process for Level III investments begins with each portfolio company, property or security being valued by the investment and/or valuation teams. With the exception of open-end funds, all unquoted Level III investment values are reviewed and approved by (i) the Company’s valuation officer, who is independent of the investment teams, (ii) a designated investment professional of each strategy and (iii) for a substantial majority of unquoted Level III holdings as measured by market value, a valuation committee of the respective strategy. For open-end funds, unquoted Level III investment values are reviewed and approved by the Company’s valuation officer. For certain investments, the valuation process also includes a review by independent valuation parties, at least annually, to determine whether the fair values determined by management are reasonable. Results of the valuation process are evaluated each quarter, including an assessment of whether the underlying calculations should be adjusted or recalibrated. In connection with this process, the Company periodically evaluates changes in fair-value measurements for reasonableness, considering items such as industry trends, general economic and market conditions, and factors specific to the investment. Certain assets are valued using prices obtained from pricing vendors or brokers. The Company seeks to obtain prices from at least two pricing vendors for the subject or similar securities. In cases where vendor pricing is not reflective of fair value, a secondary vendor is unavailable, or no vendor pricing is available, a comparison value made up of quotes for the subject or similar securities received from broker dealers may be used. These investments may be classified as Level III because the quoted prices may be indicative in nature for securities that are in an inactive market, may be for similar securities, or may require adjustment for investment-specific factors or restrictions. The Company evaluates the prices obtained from brokers or pricing vendors based on available market information, including trading activity of the subject or similar securities, or by performing a comparable security analysis to ensure that fair values are reasonably estimated. The Company also performs back-testing of valuation information obtained from pricing vendors and brokers against actual prices received in transactions. In addition to ongoing monitoring and back-testing, the Company performs due diligence procedures surrounding pricing vendors to understand their methodology and controls to support their use in the valuation process. Fair Value Option The Company has elected the fair value option for certain corporate investments that otherwise would not have reflected unrealized gains and losses in current-period earnings. Such election is irrevocable and is applied on an investment-by-investment basis at initial recognition. Unrealized gains and losses resulting from changes in fair value are reflected as a component of investment income in the condensed consolidated statements of operations. The Company’s accounting for these investments is similar to its accounting for investments held by the consolidated funds at fair value and the valuation methods are consistent with those used to determine the fair value of the consolidated funds’ investments. The Company has elected the fair value option for the financial assets and financial liabilities of its consolidated CLOs. The assets and liabilities of CLOs are primarily reflected within the investments, at fair value and within the debt obligations of CLOs line items in the condensed consolidated statements of financial condition. The Company’s accounting for CLO assets is similar to its accounting for its funds with respect to both carrying investments held by CLOs at fair value and the valuation methods used to determine the fair value of those investments. The fair value of CLO liabilities are measured as the fair value of CLO assets less the sum of (a) the fair value of any beneficial interests held by the Company and (b) the carrying value of any beneficial interests that represent compensation for services. Realized gains or losses and changes in the fair value of CLO assets, respectively, are included in net realized gain on consolidated funds’ investments and net change in unrealized appreciation (depreciation) on consolidated funds’ investments in the condensed consolidated statements of operations. Interest income of CLOs is included in interest and dividend income, and interest expense and other expenses, respectively, are included in interest expense and consolidated fund expenses in the condensed consolidated statements of operations. Changes in the fair value of a CLO’s financial liabilities in accordance with the CLO measurement guidance are included in net change in unrealized appreciation (depreciation) on consolidated funds’ investments in the condensed consolidated statements of operations. Please see notes 7 and 11 for more information.
Investments, at Fair Value	Investments, at Fair Value The consolidated funds include investment limited partnerships and CLOs that reflect their investments, including majority-owned and controlled investments, at fair value. The Company has retained the specialized investment company accounting guidance under GAAP for investment limited partnerships with respect to consolidated investments and has elected the fair value option for the financial assets of CLOs. Thus, the consolidated investments are reflected in the condensed consolidated statements of financial condition at fair value, with unrealized gains and losses resulting from changes in fair value reflected as a component of net change in unrealized appreciation (depreciation) on consolidated funds’ investments in the condensed consolidated statements of operations. Fair value is the amount 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 (i.e., the exit price). Non-publicly traded debt and equity securities and other securities or instruments for which reliable market quotations are not available are valued by management using valuation methodologies applied on a consistent basis. These securities may initially be valued at the acquisition price as the best indicator of fair value. The Company reviews the significant unobservable inputs, valuations of comparable investments and other similar transactions for investments valued at acquisition price to determine whether another valuation methodology should be utilized. Subsequent valuations will depend on the facts and circumstances known as of the valuation date and the application of valuation methodologies as further described below under “—Non-publicly Traded Equity and Real Estate Investments.” The fair value may also be based on a pending transaction expected to close after the valuation date. Exchange-traded Investments Securities listed on one or more national securities exchanges are valued at their last reported sales price on the date of valuation. If no sale occurred on the valuation date, the security is valued at the mean of the last “bid” and “ask” prices on the valuation date. Securities that are not readily marketable due to legal restrictions that may limit or restrict transferability are generally valued at a discount from quoted market prices. The discount would reflect the amount market participants would require due to the risk relating to the inability to access a public market for the security for the specified period and would vary depending on the nature and duration of the restriction and the perceived risk and volatility of the underlying securities. Securities with longer duration restrictions or higher volatility are generally valued at a higher discount. Such discounts are generally estimated based on put option models or an analysis of market studies. Instances where the Company has applied discounts to quoted prices of restricted listed securities have been infrequent. The impact of such discounts is not material to the Company’s condensed consolidated statements of financial condition and results of operations for all periods presented. Credit-oriented Investments (including Real Estate Loan Portfolios) Investments in corporate and government debt which are not listed or admitted to trading on any securities exchange are valued at the mean of the last bid and ask prices on the valuation date based on quotations supplied by recognized quotation services or by reputable broker-dealers. The market-yield approach is considered in the valuation of non-publicly traded debt securities, utilizing expected future cash flows and discounted using estimated current market rates. Discounted cash-flow calculations may be adjusted to reflect current market conditions and/or the perceived credit risk of the borrower. Consideration is also given to a borrower’s ability to meet principal and interest obligations; this may include an evaluation of collateral and/or the underlying value of the borrower utilizing techniques described below under “—Non-publicly Traded Equity and Real Estate Investments.” Non-publicly Traded Equity and Real Estate Investments The fair value of equity and real estate investments is determined using a cost, market or income approach. The cost approach is based on the current cost of reproducing a real estate investment less deterioration and functional and economic obsolescence. The market approach utilizes valuations of comparable public companies and transactions, and generally seeks to establish the enterprise value of the portfolio company or investment property using a market-multiple methodology. This approach takes into account the financial measure (such as EBITDA, adjusted EBITDA, free cash flow, net operating income, net income, book value or net asset value) believed to be most relevant for the given company or investment property. Consideration also may be given to factors such as acquisition price of the security or investment property, historical and projected operational and financial results for the portfolio company, the strengths and weaknesses of the portfolio company or investment property relative to its comparable companies or properties, industry trends, general economic and market conditions, and others deemed relevant. The income approach is typically a discounted cash-flow method that incorporates expected timing and level of cash flows. It incorporates assumptions in determining growth rates, income and expense projections, discount and capitalization rates, capital structure, terminal values, and other factors. The applicability and weight assigned to market and income approaches are determined based on the availability of reliable projections and comparable companies and transactions. The valuation of securities may be impacted by expectations of investors’ receptiveness to a public offering of the securities, the size of the holding of the securities and any associated control, information with respect to transactions or offers for the securities (including the transaction pursuant to which the investment was made and the elapsed time from the date of the investment to the valuation date), and applicable restrictions on the transferability of the securities. These valuation methodologies involve a significant degree of management judgment. Accordingly, valuations by the Company do not necessarily represent the amounts that eventually may be realized from sales or other dispositions of investments. Fair values may differ from the values that would have been used had a ready market for the investment existed, and the differences could be material to the condensed consolidated financial statements.
Recent Accounting Developments	Recent Accounting Developments In January 2017, the Financial Accounting Standards Board (“FASB”) issued guidance to simplify the accounting for goodwill impairments by eliminating step 2 of the goodwill impairment test. This step currently requires an entity to perform a hypothetical purchase price allocation to derive the implied fair value of goodwill. Under the new guidance, an impairment loss is recognized if the carrying value of a reporting unit exceeds its fair value. The impairment loss would equal the amount of that excess, limited to the total amount of goodwill. All other goodwill impairment guidance remains largely unchanged. Entities will continue to have the option to perform a qualitative assessment to determine if a quantitative impairment test is necessary. The guidance is effective for the Company in the first quarter of 2020 on a prospective basis, with early adoption permitted. The Company expects that adoption of this guidance will not have a material impact on the consolidated financial statements. In August 2016, the FASB issued guidance on the classification of certain cash receipts and payments in the statement of cash flows. The amendments add to or clarify guidance on a number of cash flow issues, including debt prepayment or debt extinguishment costs, contingent consideration payments made after a business combination, distributions received from equity-method investees and beneficial interests in securitization transactions. The Company adopted this guidance in the first quarter of 2018 on a retrospective basis. The impact of adoption was not material to the Company’s consolidated financial statements. In February 2016, the FASB issued guidance that will require a lessee to recognize a lease asset and a lease liability for most of its operating leases. Under current GAAP, operating leases are not recognized by a lessee in its statements of financial position. In general, the new asset and liability will each equal the present value of lease payments. The guidance does not significantly change the recognition, measurement and presentation of expenses and cash flows arising from a lease by a lessee. The Company expects to adopt the guidance in the first quarter of 2019 under the simplified transition method approved by the FASB in March 2018. 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 does not expect that adoption will have a material impact on the consolidated statements of operations because all of the Company’s leases are currently classified as operating leases, which under the guidance will continue to be recognized as expense on a straight-line basis. The adoption, however, will result in a significant gross-up in total assets and total liabilities on the consolidated statements of financial position. The gross-up impact as of June 30, 2018 is estimated to be approximately $129 million , which represents the aggregate discounted amount of the Company’s minimum lease payments under lease obligations as of June 30, 2018. In May 2014, the FASB issued guidance on revenue recognition that superseded most existing revenue recognition guidance, including industry-specific guidance. The guidance outlined a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers, and provides a largely principles-based framework for addressing revenue recognition issues on a comprehensive basis. Under the guidance, revenue is recognized when an entity satisfies a performance obligation by transferring control of a promised good or service to a customer in an amount that reflects the consideration for which the entity expects to be entitled for that good or service. The guidance also requires qualitative and quantitative disclosures about revenue that has been recognized and revenue that is expected to be recognized in the future from existing contracts, significant judgments and changes in those judgments made by management in recognizing revenue, disaggregation of revenue, and information about contract balances. The Company adopted this guidance in the first quarter of 2018 on a modified retrospective basis. The most significant effect of the guidance for the Company relates to the recognition of incentive income. The guidance requires the Company to recognize incentive income when it concludes that it is probable that significant reversals of revenue will not occur in subsequent periods. Under legacy GAAP, the amount of incentive income recognized by the Company was generally limited to the amount not contingent on a future event. Upon adoption, the Company recorded a cumulative-effect increase to unitholders’ capital of $ 48.7 million , net of tax, as of January 1, 2018. This adjustment relates to incentive income that would have met the “probable that significant reversal will not occur” criteria as of that date. In addition, effective January 1, 2018, certain reimbursements received by the Company from the investment funds it manages are reported as revenues on a gross basis with an equal offset to expenses in the consolidated statements of operations. Please see note 4 for more information on revenues.

An increase (decrease) in the discount rate would result in a lower (higher) fair-value measurement. (2) Multiple of either earnings or underlying assets is the significant unobservable input used in the market approach for the fair-value measurement of distressed credit-oriented investments, credit-oriented investments in which the consolidated funds have a controlling interest in the underlying issuer, equity investments and certain real estate-oriented investments. An increase (decrease) in the multiple would result in a higher (lower) fair-value measurement. (3) The weighted average is based on the fair value of the investments included in the range. (4) A discounted cash-flow method is generally used to value performing credit-oriented investments in which the consolidated funds do not have a controlling interest in the underlying issuer, as well as certain equity investments, real estate-oriented investments and real estate loan portfolios. (5) Certain investments are valued using vendor prices or broker quotes for the subject or similar securities. Generally, investments valued in this manner are classified as Level III because the quoted prices may be indicative in nature for securities that are in an inactive market, may be for similar securities, or may require adjustment for investment-specific factors or restrictions. (6) A market approach is generally used to value distressed investments and investments in which the consolidated funds have a controlling interest in the underlying issuer. (7) Earnings multiples are based on comparable public companies and transactions with comparable companies. The Company typically utilizes multiples of EBITDA; however, in certain cases the Company may use other earnings multiples believed to be most relevant to the investment. The Company typically applies the multiple to trailing twelve-months’ EBITDA. However, in certain cases other earnings measures, such as pro forma EBITDA, may be utilized if deemed to be more relevant. (8) Certain investments are valued based on recent transactions, generally defined as investments purchased or sold within six months of the valuation date. The fair value may also be based on a pending transaction expected to close after the valuation date.
