Overview	'
	1	OVERVIEW
	Och-Ziff Capital Management Group LLC (the “Registrant”), a Delaware limited liability company, together with its consolidated subsidiaries (collectively, the “Company”), is a global alternative asset management firm with offices in New York, London, Hong Kong, Mumbai, Beijing and Dubai. The Company provides asset management services to its investment funds (the “Och-Ziff funds” or the “funds”), which pursue a broad range of global investment opportunities. The Company currently manages multi-strategy, credit, real estate and equity funds, collateralized loan obligations (“CLOs”) and other alternative investment vehicles.
	The Company’s primary sources of revenues are management fees, which are based on the amount of the Company’s assets under management, and incentive income, which is based on the investment performance of its funds. Accordingly, for any given period, the Company’s revenues will be driven by the combination of assets under management and the investment performance of the Och-Ziff funds.
	The Company conducts substantially all of its operations through its one reportable segment, the Och-Ziff Funds segment, which provides asset management services to its multi-strategy, credit and equity funds, CLOs and other alternative investment vehicles. The Company’s Other Operations are primarily comprised of its real estate business, which provides asset management services to its real estate funds. The businesses included in the Company’s Other Operations do not meet the thresholds of reportable business segments under U.S. generally accepted accounting principles (“GAAP”).
	The Company generates substantially all of its revenues in the United States. The liability of the Company’s Class A Shareholders is limited to the extent of their capital contributions.
	The Company conducts substantially all of its operations through OZ Management LP, OZ Advisors LP and OZ Advisors II LP and their consolidated subsidiaries (collectively, the “Och-Ziff Operating Group”). References to the Company’s “executive managing directors” refer to the current limited partners of OZ Management LP, OZ Advisors LP and OZ Advisors II LP other than the Company’s intermediate holding companies, including the Company’s founder, Mr. Daniel S. Och, and, except where the context requires otherwise, include certain limited partners who are no longer active in the business of the Company. References to the Company’s “active executive managing directors” refer to executive managing directors who remain active in the Company’s business. References to the “Ziffs” refer collectively to Ziff Investors Partnership, L.P. II and certain of its affiliates and control persons. References to the Company’s “intermediate holding companies” refer, collectively, to Och-Ziff Holding Corporation (“Och-Ziff Corp”) and Och-Ziff Holding LLC, both of which are wholly owned subsidiaries of the Registrant.

Basis of Presentation and Significant Accounting Policies	'
	2	BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	Basis of Presentation
	These unaudited, interim, consolidated financial statements are prepared in accordance with GAAP as set forth in the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”), and should be read in conjunction with the audited consolidated financial statements included in the Company’s annual report on Form 10-K for the year ended December 31, 2013 (the “Annual Report”). In the opinion of management, all adjustments considered necessary for a fair presentation of the Company’s unaudited, interim, consolidated financial statements have been included and are of a normal and recurring nature. The results of operations presented for the interim periods are not necessarily indicative of the results that may be expected for any other interim period or for the entire year, primarily because of the majority of incentive income and discretionary cash bonuses being recorded in the fourth quarter each year. All significant intercompany transactions and balances have been eliminated in consolidation.
	As discussed in Note 17, the Company restated the quarterly amounts previously reported in its Form 10-Qs for the first through third quarters of 2013. See Note 17 for additional information.
	Recently Adopted Accounting Pronouncements
	None of the changes to GAAP that went into effect in the nine months ended September 30, 2014 has had a material effect on the Company’s consolidated financial statements.
	Future Adoption of Accounting Pronouncements
	In May 2014, the FASB issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers. ASU 2014-09 supersedes the revenue recognition requirements in ASC 605—Revenue Recognition and most industry-specific guidance throughout the Codification. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Entities are permitted to apply the guidance in ASU 2014-09 using one of the following methods: (1) full retrospective application to each prior period presented, or (2) modified retrospective application with a cumulative effect adjustment to opening retained earnings in the annual reporting period that includes that date of initial application. The requirements of ASU 2014-09 are effective for the Company beginning in the first quarter of 2017. The Company is currently evaluating the impact, if any, that these updates will have on its financial condition and results of operations.
	In August 2014, the FASB issued ASU 2014-13, Measuring the Financial Assets and the Financial Liabilities of a Consolidated Collateralized Financing Entity. ASU 2014-13 amends ASC 810—Consolidation to address the measurement difference that may occur between the fair value, as determined under GAAP, of the financial assets and financial liabilities of a consolidated collateralized financing entity, such as a CLO. The new guidance provides a measurement alternative which allows entities to measure both the financial assets and financial liabilities of the consolidated collateralized financing entity using the more observable of the fair value of the financial assets and the fair value of the financial liabilities. The requirements of ASU 2014-13 are effective for the Company beginning in the first quarter of 2016, with early adoption permitted in the first quarter of 2015. The Company is currently evaluating the impact that this update will have on its financial condition and results of operations.
	None of the other changes to GAAP that are not yet effective is expected to have a material effect on the Company's consolidated financial statements.

Noncontrolling Interests	'
	3		NONCONTROLLING INTERESTS
	Noncontrolling interests represent ownership interests in the Company’s subsidiaries held by parties other than the Company, and primarily relate to the Och-Ziff Operating Group A Units held by the Company’s executive managing directors and the Ziffs (until they exchanged their remaining interests during the 2014 second quarter) and fund investors’ interests in the consolidated Och-Ziff funds. Net income allocated to the Och-Ziff Operating Group A Units is driven by the earnings of the Och-Ziff Operating Group. Net income allocated to fund investors’ interests in consolidated Och-Ziff funds is driven by the earnings of those funds, including the net difference in the fair value of CLO assets and liabilities that are subsequently reclassified to appropriated retained earnings on the consolidated balance sheets.
	The following table presents the components of the net income allocated to noncontrolling interests:
		Three Months Ended				Nine Months Ended

	Och-Ziff Operating Group Ownership
	The Company’s interest in the Och-Ziff Operating Group increased to 36.3% as of September 30, 2014, from 35.9% as of December 31, 2013. Increases in the Company’s interest in the Och-Ziff Operating Group were driven by the exchange of Och-Ziff Operating Group A Units for an equal number of Class A Shares and the issuance of Class A Shares under the Company’s Amended and Restated 2007 Equity Incentive Plan, primarily related to the vesting of Class A restricted share units (“RSUs”). The Company also makes awards under its 2013 Incentive Plan, which may result in the issuance of Class A Shares in the future, primarily related to the vesting of RSUs or the exchange of Och-Ziff Operating Group A Units. The Company’s interest in the Och-Ziff Operating Group is expected to continue to increase over time as additional Class A Shares are issued upon the exchange of Och-Ziff Operating Group A Units and vesting of RSUs. These increases will be offset upon any conversion of Och-Ziff Operating Group D Units, which are not considered equity for GAAP purposes, into Och-Ziff Operating Group A Units.
	Och-Ziff Operating Group A Unit Exchanges
	During the nine months ended September 30, 2014, the Company issued 1,345,472 Class A Shares in connection with the Ziffs’ exchange of an equal number of Och-Ziff Operating Group A Units. As a result, the Company recorded an increase to shareholders’ equity related to deferred income tax assets resulting from the exchange, net of an increase in the tax receivable agreement liability. Following such exchange, the Ziffs ceased to own any Och-Ziff Operating Group A Units.

	Fair value represents the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between market participants as of the measurement date (i.e., an exit price). Due to the inherent uncertainty of valuations of investments that are determined to be illiquid or do not have readily ascertainable fair values, the estimates of fair value may differ from the values ultimately realized, and those differences can be material.
	GAAP prioritizes the level of market price observability used in measuring assets and liabilities at fair value. Market price observability is impacted by a number of factors, including the type of assets and liabilities and the specific characteristics of the assets and liabilities. Assets and liabilities with readily available, actively quoted prices or for which fair value can be measured from actively-quoted prices generally will have a higher degree of market price observability and lesser degree of judgment used in measuring fair value.
	Assets and liabilities measured at fair value are classified into one of the following categories:
	•	Level I – Fair value is determined using quoted prices that are available in active markets for identical assets or liabilities. The types of assets and liabilities that would generally be included in this category are certain listed equities, U.S. Treasury obligations and certain listed derivatives.
	•	Level II – Fair value is determined using quotations received from dealers making a market for these assets or liabilities (“broker quotes”), valuations obtained from independent third-party pricing services, the use of models or other valuation methodologies based on pricing inputs that are either directly or indirectly market observable as of the measurement date. The types of assets and liabilities that would generally be included in this category are certain corporate bonds, certain credit default swap contracts, certain bank debt securities, certain commercial real estate debt, less liquid and restricted equity securities, forward contracts and certain over the-counter (“OTC”) derivatives.
	•	Level III – Fair value is determined using pricing inputs that are unobservable in the market and includes situations where there is little, if any, market activity for the asset or liability. The fair value of assets and liabilities in this category may require significant judgment or estimation in determining fair value of the assets or liabilities. The fair value of these assets and liabilities may be estimated using a combination of observed transaction prices, independent pricing services, relevant broker quotes, models or other valuation methodologies based on pricing inputs that are neither directly or indirectly market observable. The types of assets and liabilities that would generally be included in this category include real estate investments, equity and debt securities issued by private entities, limited partnerships, certain corporate bonds, certain credit default swap contracts, certain bank debt securities, certain commercial real estate debt, certain OTC derivatives, residential and commercial mortgage-backed securities, asset-backed securities, collateralized debt obligations, as well as the notes payable of consolidated CLOs.
	In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, an asset or liability’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. The assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability.
	The assets and liabilities presented in the tables below belong to the investors in the consolidated funds. The Company has a minimal, if any, investment in these funds.

Valuation Methodologies for Fair Value Measurements Categorized within Levels II and III
Real Estate Investments
Real estate investments are generally structured as equity, preferred equity, mezzanine debt, and participating debt in entities domiciled primarily in the United States and include investments in lodging, gaming, multifamily properties, retail, healthcare, distressed residential, senior housing, golf, parking, office buildings and land. The fair values of these investments are generally based upon discounting the expected cash flows from the investment or a cash flow multiple. In reaching the determination of fair value for investments, the Company considers many factors including, but not limited to: the operating cash flows and financial performance of the real estate investments relative to budgets or projections; property types; geographic locations; the physical condition of the asset; prevailing market capitalization rates; prevailing market discount rates; general economic conditions; economic conditions specific to the market in which the assets are located; the prevailing interest rate environment; the prevailing state of the debt markets; comparable public company trading multiples; independent third-party appraisals; available pricing data on comparable properties in the specific market in which the asset is located; expected exit timing and strategy; and any specific rights or terms associated with the investment.
The significant unobservable inputs used in the fair value measurement of the Company’s real estate investments are discount rates, cash flow growth rates, capitalization rates, the price per square foot, the absorption percentage per year and exit multiples. Significant increases (decreases) in the discount rates and capitalization rates in isolation would be expected to result in a significantly lower (higher) fair value measurement. Significant increases (decreases) in the cash flow growth rates, the price per square foot, the absorption percentage per year and exit multiples in isolation would be expected to result in a significantly higher (lower) fair value measurement. A change in the assumption used for price per square foot is generally accompanied by a directionally inverse change in the absorption percentage per year.
Bank Debt; Residential and Commercial Mortgage-Backed Securities; Collateralized Debt Obligations; Commercial Real Estate Debt; Corporate Bonds; Asset-Backed Securities; Notes Payable of Consolidated CLOs
The fair value of investments in bank debt, residential and commercial mortgage-backed securities, collateralized debt obligations, commercial real estate debt, corporate bonds, asset-backed securities and notes payable of consolidated CLOs that do not have readily ascertainable fair values is generally determined using broker quotes or independent pricing services. For month-end valuations, the Company generally receives one to four broker quotes for each security, depending on the type of security being valued. These broker quotes are generally non-binding or indicative in nature. The Company verifies that these broker quotes are reflective of fair value as defined in GAAP generally through procedures such as comparison to independent pricing services, back testing procedures, review of stale pricing reports and performance of other due diligence procedures as may be deemed necessary. Historically, the Company has only adjusted a small number of broker quotes when used in determining final valuations for securities as a result of these procedures.
To the extent broker quotes are not available or deemed unreliable, the methods and procedures to value these investments may include, but are not limited to: obtaining and using other additional broker quotes deemed reliable; using independent pricing services; performing comparisons with prices of comparable or similar securities; obtaining valuation-related information from the issuers; calculating the present value of future cash flows; assessing other analytical data and information relating to these investments that is an indication of their value; obtaining information provided by third parties; reviewing the amounts invested in these investments; and evaluating financial information provided by the management of these investments. Market data is used to the extent that it is observable and considered reliable.
The significant unobservable inputs used in the fair value measurement of the Company’s bank debt, residential and commercial mortgage-backed securities, commercial real estate debt, corporate bonds and asset-backed securities that are not valued using broker quotes or independent pricing services are discount rates, credit spreads and yields. Significant increases (decreases) in the discount rates, credit spreads and yields in isolation would be expected to result in a significantly lower (higher) fair value measurement.
During the first quarter of 2014, the Company changed the valuation methodology for its senior secured notes payable of consolidated CLOs from discounted cash flows to broker quote. The use of broker quotes is generally consistent with the valuation methodologies of the Company's other credit investments.
Energy and Natural Resources Limited Partnerships
The fair value of energy and natural resources limited partnerships are generally determined using discounted cash flows when assets are producing oil or gas, or when it is reasonably certain that an asset will be capable of producing oil or gas, or using recent financing for certain investments. Acreage with proven undeveloped, probable or possible reserves are valued using prevailing prices of comparable properties, and may include adjustments for other assets or liabilities such as seismic data, equipment, and cash held by the investee. Certain natural resource assets may also be valued using scenario analyses and sum of the parts analyses.
The fair value for certain energy and natural resources limited partnership investments is based on the net asset value of the underlying fund. This amount represents a certain consolidated fund’s investment into another fund managed by the Company. The investee invests primarily in energy and natural resource investments. The fund may not redeem its investment into the investee prior to liquidation. The fund will receive distributions from the investee as investments are sold, the timing of which cannot be estimated. The consolidated fund has $46.8 million of unfunded commitments that will be funded by capital contributions from investors in the fund, as the Company is not an investor in the fund.
The significant unobservable inputs used in the fair value measurement of the Company’s energy and natural resources limited partnerships are discount rates, EBITDA multiples, price per acre, production multiples, EV/risked prospective resources, price of natural gas per thousand cubic feet, price of oil per barrel and well risking. Significant increases (decreases) in the discount rates and well risking in isolation would be expected to result in a lower (higher) fair value measurement. Significant increases (decreases) in the EBITDA multiples, price per acre, production multiples, EV/risked prospective resources, price of natural gas per thousand cubic feet and price of oil per barrel in isolation would be expected to result in a significantly higher (lower) fair value measurement.
Investments in Affiliated Credit Funds
The fair value of investments in affiliated credit funds relates to consolidated feeder funds’ investments into their related master funds. The Company is not an investor of these feeder funds or master funds. The fair value of these investments is based on the consolidated feeder funds’ proportionate share of the respective master funds’ net asset value. These master funds invest primarily in credit-related strategies. Approximately 73% of these investments can be redeemed and paid to investors in the feeder fund after an initial lock-up period of one to three years, after which the feeder fund may redeem its investment on a quarterly basis upon 90 days’ prior written notice. The Company, as investment manager of the master fund, has the option (not exercised to date) to suspend redemptions in certain situations. The remaining 27% relates to a feeder fund that is not able to redeem its investment in the master fund prior to liquidation, the timing of which cannot be estimated. The feeder fund will receive distributions from the master fund as investments are sold, the timing of which cannot be estimated due to the illiquid nature of the investments held by the master fund. The consolidated feeder funds have $24.6 million of unfunded commitments that will be funded by capital contributions from investors in the feeder funds, as the Company is not an investor in the feeder funds or master funds.

Valuation Process for Fair Value Measurements Categorized within Level III
The Company has established an internal control infrastructure over the valuation of financial instruments that includes ongoing oversight by its Financial Controls Group and Valuation Committee, as well as periodic audits by the Company’s Internal Audit Group. These control functions are segregated from the trading and investing functions.
The Valuation Committee is responsible for establishing the valuation policy and monitors compliance of the valuation policy, ensuring that all of the funds’ investments reflect fair values, as well as providing oversight of the valuation process. These valuation policies and procedures include, but are not limited to the following: determining the pricing sources used to value specific investment classes; the selection of independent pricing services; the periodic review of due diligence materials of independent pricing services; and the fair value hierarchy coding of the funds’ investments. The Valuation Committee reviews a variety of reports on a monthly basis, which include, but are not limited to the following: summaries of the sources used to determine the value of the funds’ investments; summaries of the fair value hierarchy of the funds’ investments; and variance reports that compare the values of investments to independent pricing services. The Valuation Committee is comprised of non-investment professionals, and may obtain input from investment professionals for consideration in carrying out its responsibilities.
The Financial Controls Group is responsible for seeking to ensure compliance with the valuation policies, performing price verification and preparing the monthly valuation reports reviewed by the Valuation Committee. The Financial Controls Group’s other responsibilities include, but are not limited to the following: preparation and distribution of daily profit and loss reports; overseeing the collection and evaluation of counterparty prices, broker-dealer quotations, exchange prices and third party pricing feeds; performing back testing by comparing prices observed in executed transactions to previous day valuations and/or pricing service providers on a weekly and monthly basis; preparing due diligence report reviews on independent pricing services on an annual or as needed basis; and assisting the Valuation Committee in developing valuation policies.
The Internal Audit Group employs a risk-based program of audit coverage that is designed to provide an assessment of the design and effectiveness of controls over the Company’s operations, regulatory compliance, valuation of financial instruments and reporting. Additionally, the Internal Audit Group meets with management periodically to evaluate and provide guidance on the existing risk framework and control environment assessments.
Monthly procedures have been established for Level III investments, which includes comparing unobservable inputs to observable inputs for similar positions, reviewing subsequent market activities, performing comparisons of actual versus projected performance indicators, and discussing the valuation methodology, including pricing techniques when applicable, with investment professionals. Independent pricing services may be used to corroborate the Company’s internal valuations. Investment professionals and members of the Financial Controls Group review a daily profit and loss report, as well as other periodic reports that analyze the profit and loss and related asset class exposure of the funds’ investments.
Fair Value of Other Financial Instruments
Management estimates that the fair value of the $381.3 million outstanding under the Company’s delayed draw term loan agreement entered into in November 2011 (the “Delayed Draw Term Loan”) was approximately 98% of its carrying value as of September 30, 2014, based on an analysis of comparable issuers. The carrying value of the Company’s other financial instruments approximated their fair values as of September 30, 2014. These fair value measurements would be categorized as Level III within the fair value hierarchy.

	5	BALANCE SHEET OFFSETTING
	In the ordinary course of business, certain consolidated funds have entered into certain transactions that are subject to master agreements that provide for payment netting and that, in the case of a default or similar event with respect to the counterparty to the master agreement, provide for netting across transactions. Generally, upon a counterparty default, the fund can terminate all transactions under the master agreement and set off amounts it owes across all transactions under a particular master agreement against collateral it has received under such master agreement; provided, however, that in the case of certain defaults, the fund may only be able to terminate and setoff solely with respect to the transactions affected by the default. Generally, the funds party to these agreements manage cash and securities collateral on a counterparty basis as permitted under each master agreement.
	The table below presents the repurchase agreements that are set off, if any, as well as securities transferred to counterparties related to those repurchase agreements (capped so that the net amount presented will not be reduced below zero). No other material financial instruments were subject to master netting agreements or other similar agreements.

Variable Interest Entities	'
	6		VARIABLE INTEREST ENTITIES
	In the ordinary course of business, the Company sponsors the formation of VIEs. These VIEs generally consist of the following categories: funds, including CLOs, and joint ventures. The Company has not recorded any liabilities with respect to VIEs that are not consolidated.
	Funds
	Many of the Company’s funds, including its CLOs, are VIEs. The Company generally serves as the general partner or the investment or collateral manager with decision-making rights for these entities. Substantially all of the funds that are VIEs managed by the Company qualify for the deferral granted under ASU 2010-10, Amendments to Statement 167 for Certain Investment Funds. Accordingly, the Company’s determination of whether it is the primary beneficiary of a fund that is a VIE is generally based on identifying the variable interest holder that is exposed to the majority of the expected losses or receives a majority of the expected residual returns. Fund investors are entitled to substantially all of the economics of these VIEs with the exception of management fees and incentive income, if any, earned by the Company. Accordingly, the determination of whether the Company is the primary beneficiary of these entities is not impacted by changes in the underlying assumptions made regarding future results or expected cash flows of these VIEs.
	The Company acts as collateral manager for CLOs that are VIEs. CLOs are entities that issue collateralized notes that offer investors the opportunity for returns that vary commensurately with the risk they assume. The notes issued by the CLOs are generally backed by asset portfolios consisting of loans or other debt. The Company receives collateral management fees for acting as collateral manager to the CLOs, and may earn incentive income based on the performance of the CLOs, subject to hurdle rates.
	The deferral granted in ASU 2010-10 does not apply to CLOs. Accordingly, the determination of whether the Company is the primary beneficiary that would consolidate a CLO is based on a qualitative assessment to determine whether the Company, as collateral manager, has (i) the power to direct the activities of the CLO that most significantly impact its economic performance, and (ii) the obligations to absorb losses or the right to receive benefits from the CLO that could potentially be significant to the CLO. The Company determined that when it launches its CLOs, it possesses the power to direct the activities of the CLOs that most significantly impact the CLOs’ economic performance through its role in managing collateral and credit risk as the collateral manager. In addition, the Company determined that when it launches its CLOs, it has the right to receive benefits from the CLOs that could potentially be significant, on a quantitative and qualitative basis, because of the management fees and incentive income the Company could earn from the CLOs, as well as the purpose and design of the CLOs. As a result, the Company consolidates the CLOs it manages upon launch.
	The following table presents the assets and liabilities of funds that are VIEs and consolidated by the Company:
		September 30, 2014				December 31, 2013

	Total Liabilities	$	4,808,243	$	11,850	$	2,777,270	$	51,854
	The assets presented in the table above belong to the investors in those funds, are available for use only by the fund to which they belong, and are not available for use by the Company. The consolidated funds have no recourse to the general credit of the Company with respect to any liability. The Company also consolidates funds that are not VIEs, and therefore the assets and liabilities of those funds are not included in the table above.
	The Company’s involvement with funds that are VIEs and not consolidated by the Company is generally limited to providing asset management services. The Company’s exposure to loss from these entities is limited to a decrease in the management fees and incentive income that may be earned in future periods, as well as the loss of investments in these entities, if any. The net assets of these VIEs were $36.6 billion and $33.7 billion as of September 30, 2014 and December 31, 2013, respectively. The Company does not provide, nor is it required to provide, any type of financial or other support to these entities. The Company’s variable interests related to these VIEs relate primarily to management fees and incentive income earned from these entities, as well as investments in these entities, if any. As of September 30, 2014 and December 31, 2013, the only assets arising from these variable interests related to income and fees receivable of $20.4 million and $574.1 million, respectively.
	Joint Ventures
	The Company holds a variable interest in a joint venture that is a VIE. The Company’s exposure to loss for this joint venture is limited to its investments in the entity, which totaled $231 thousand and $6.7 million as of September 30, 2014 and December 31, 2013, respectively, and is recorded within other assets in the Company’s consolidated balance sheets.

	Notes Payable of Consolidated CLOs
	The Company consolidates the CLOs it manages. As a result, the senior and subordinated notes issued by the CLOs are included in the Company’s consolidated balance sheets. Notes payable of the consolidated CLOs are collateralized by the assets held by the CLOs and the assets of one CLO may not be used to satisfy the liabilities of another. This collateral generally consists of corporate loans, corporate bonds and other securities. As of September 30, 2014 and December 31, 2013, the fair value of the CLO assets was $4.8 billion and $2.8 billion, respectively. The stated maturity dates for the notes issued by the CLOs range from 2023 to 2026.
	The Company has elected to carry these notes at fair value in its consolidated balance sheets to mitigate the accounting mismatch between the carrying values of the assets and liabilities of the consolidated CLOs. The Company recorded unrealized gains of $20.6 million and $11.0 million for the three months ended September 30, 2014 and 2013, respectively, and $17.7 million and $23.6 million for the nine months ended September 30, 2014 and 2013, respectively. These amounts are included within net gains (losses) of consolidated Och-Ziff funds in the statements of comprehensive income. Substantially all of these changes related to changes in instrument specific credit risk, as substantially all of these are floating-rate instruments.
	The tables below present information related to the CLO notes outstanding. The subordinated notes have no stated interest rate, and are entitled to any excess cash flows after contractual payments are made to the senior notes.

	Aircraft Loan
	On February 14, 2014, the Company entered into a secured multiple draw term loan agreement for up to $59.0 million to finance the purchase of a new corporate aircraft expected to be delivered in the first quarter of 2015 (the “Aircraft Loan”). The Aircraft Loan is guaranteed by OZ Management, OZ Advisors and OZ Advisors II. As of September 30, 2014, $48.7 million was outstanding under the Aircraft Loan.
	Amounts borrowed prior to aircraft delivery to fund progress payments under the aircraft purchase agreement bear interest at a rate of LIBOR plus 1.40%. Following aircraft delivery, the Company will have the option of selecting a 5- or 7-year term with either a fixed or floating interest rate, which rate will vary based on the term selected. There are no financial covenants associated with the Aircraft Loan. No principal payments are due prior to aircraft delivery; however, the Aircraft Loan will become due if the aircraft is not delivered by October 30, 2015. Following aircraft delivery, borrowings under the Aircraft Loan will be payable in installments for the term of the facility, with a balloon payment due upon maturity. The amount of the installment and balloon payments will be determined based upon the selection of either a 5- or 7-year term. The Aircraft Loan includes other customary terms and conditions, including customary events of default and covenants.

	11		INCOME TAXES
	The computation of the effective tax rate and provision at each interim period requires the use of certain estimates and significant judgment including, but not limited to, the expected operating income for the year, projections of the proportion of income earned and taxed in foreign jurisdictions, permanent differences, and the likelihood of recovering deferred tax assets existing as of the balance sheet date. The estimates used to compute the provision for income taxes may change as new events occur, additional information is obtained or as tax laws and regulations change. Additionally, the Company records the majority of its incentive income and discretionary cash bonuses in the fourth quarter each year. Accordingly, the effective tax rate for interim periods is not indicative of the tax rate expected for a full year.
	The Registrant and each of the Och-Ziff Operating Group entities are partnerships for U.S. federal income tax purposes. Due to the Company’s legal structure, only a portion of the income earned by the Company is subject to corporate-level tax rates in the United States and in foreign jurisdictions.
	The provision for income taxes includes federal, state and local taxes in the United States and foreign taxes at an approximate effective tax rate of 24.2% and 6.6% for the three months ended September 30, 2014 and 2013, respectively, and 17.4% and 8.6% for the nine months ended September 30, 2014 and 2013, respectively. The reconciling items from the Company’s statutory rate to the effective tax rate were driven primarily by the following: (i) a portion of the income earned by the Company is not subject to federal, state and local corporate income taxes in the United States; (ii) a portion of the income earned by the Company is subject to the New York City unincorporated business tax; (iii) certain foreign subsidiaries are subject to foreign corporate income taxes; and (iv) the Reorganization expenses related to the reclassification of the executive managing directors’ and the Ziffs’ interests as Och-Ziff Operating Group A Units are not deductible for tax purposes.
	In accordance with GAAP, the Company recognizes tax benefits for amounts that are “more likely than not” to be sustained upon examination by tax authorities. For uncertain tax positions in which the benefit to be realized does not meet the “more likely than not” threshold, the Company establishes a liability, which is included within other liabilities in the consolidated balance sheets.
	A reconciliation of the changes in the Company’s unrecognized tax benefits, excluding related interest and penalties, is presented in the table below. As of and prior to December 31, 2013, the Company did not have a liability for unrecognized tax benefits.

As of September 30, 2014, the Company does not believe that there will be a significant change to the uncertain tax positions during the next 12 months. The Company’s total unrecognized tax benefits that, if recognized, would affect its effective tax rate was $4.5 million as of September 30, 2014.

Earnings Per Class A Share	'
	12		EARNINGS PER CLASS A SHARE
	Basic earnings per Class A Share is computed by dividing the net income allocated to Class A Shareholders by the weighted-average number of Class A Shares outstanding for the period. For the three months ended September 30, 2014 and 2013, the Company included, respectively, 1,091,238 and 1,600,165 RSUs that have vested but have not been settled in Class A Shares in the weighted-average Class A Shares outstanding used in the calculation of basic and diluted earnings per Class A Share. For the nine months ended September 30, 2014 and 2013, the Company included, respectively, 1,512,577 and 1,854,084 RSUs that have vested but have not been settled in Class A Shares in the weighted-average Class A Shares outstanding used in the calculation of basic and diluted earnings per Class A Share.

	13		RELATED PARTY TRANSACTIONS
	Due to Related Parties
	Amounts due to related parties relate primarily to future payments owed to the Company’s executive managing directors and the Ziffs under the tax receivable agreement. As further discussed in Note 14, the Company entered into an agreement with the executive managing directors and the Ziffs, whereby the Company would pay them a portion of any tax savings resulting from the purchase of Och-Ziff Operating Group A Units at the time of the 2007 Offerings or as a result of any subsequent exchanges of their interests for Class A Shares.
	Notes Payable of Consolidated CLOs
	A portion of the notes payable of consolidated CLOs is held by certain funds managed by the Company. As of September 30, 2014 and December 31, 2013, these amounts totaled $181.9 million and $162.8 million, respectively.
	Management Fees and Incentive Income Earned from the Och-Ziff Funds
	The Company earns substantially all of its management fees and incentive income from the Och-Ziff funds, which are considered related parties as the Company manages the operations of and makes investment decisions for these funds.
	Management Fees and Incentive Income Earned from Related Parties and Waived Fees
	Prior to the 2007 Offerings, the Company did not charge management fees or earn incentive income on investments made by the Company’s executive managing directors, employees and other related parties. Following the 2007 Offerings, the Company began charging management fees and earning incentive income on new investments made in the funds by executive managing directors and certain other related parties, including the reinvestment by executive managing directors of the after-tax proceeds from the 2007 Offerings. The Company continues to waive fees for employee investments in the funds.
	The following table presents management fees and incentive income charged on investments held by related parties and amounts waived by the Company for related parties before the impact of eliminations related to the consolidated funds:
		Three Months Ended September 30,				Nine Months Ended September 30,

	Corporate Aircraft
	The Company’s corporate aircraft is used primarily for business purposes. From time to time, Mr. Och uses the aircraft for personal use. For the three months ended September 30, 2014 and 2013, the Company charged Mr. Och $125 thousand and $94 thousand, respectively, for his personal use of the aircraft. For the nine months ended September 30, 2014 and 2013, the Company charged Mr. Och $474 thousand and $499 thousand, respectively, for his personal use of the aircraft.

	14	COMMITMENTS AND CONTINGENCIES
	Tax Receivable Agreement
	The purchase of Och-Ziff Operating Group A Units from the executive managing directors and the Ziffs with the proceeds from the 2007 Offerings, and subsequent taxable exchanges by them of Och-Ziff Operating Group A Units for Class A Shares on a one-for-one basis (or, at the Company’s option, a cash equivalent), resulted, and, in the case of future exchanges, are anticipated to result, in an increase in the tax basis of the tangible and intangible assets of the Och-Ziff Operating Group that would not otherwise have been available. As a result, the Company expects that its future tax liability will be reduced. Pursuant to the tax receivable agreement entered into among the Company, the executive managing directors and the Ziffs, the Company has agreed to pay to the executive managing directors and the Ziffs 85% of the amount of tax savings, if any, actually realized by the Company.
	The Company recorded its initial estimate of future payments under the tax receivable agreement by recording a decrease to paid-in capital and an increase in amounts due to related parties in the consolidated financial statements. Subsequent adjustments to the liability for future payments under the tax receivable agreement related to changes in estimated future tax rates or state income tax apportionment are recognized through current period earnings within general, administrative and other expenses in the consolidated statements of comprehensive income.
	In connection with the departure of certain former executive managing directors since the 2007 Offerings, the right to receive payments under the tax receivable agreement by those former executive managing directors was contributed to the Och-Ziff Operating Group. As a result, the Company now expects to pay to the remaining executive managing directors and the Ziffs approximately 78% (from 85% at the time of the 2007 Offerings) of the amount of cash savings, if any, in federal, state and local income taxes in the United States that the Company actually realizes as a result of the increases in tax basis.
	The estimate of the timing and the amount of future payments under the tax receivable agreement involves several assumptions that do not account for the significant uncertainties associated with these potential payments, including an assumption that Och-Ziff Corp will have sufficient taxable income in the relevant tax years to utilize the tax benefits that would give rise to an obligation to make payments. The actual timing and amount of any actual payments under the tax receivable agreement will vary based upon these and a number of other factors.
	Lease Obligations
	The Company has non-cancelable operating leases for its headquarters in New York expiring in 2029 and various other operating leases for its offices in London, Hong Kong, Mumbai, Beijing and Dubai expiring on various dates through 2024. The Company also has operating leases for other locations, as well as operating leases on computer hardware. Certain operating leases allow for rent holiday periods. The Company recognizes expense related to its operating leases on a straight-line basis over the lease term taking into account these rent holiday periods. The related lease commitments have not changed materially since December 31, 2013.
	Litigation
	From time to time, the Company is involved in litigation and claims incidental to the conduct of the Company’s business. The Company is also subject to extensive scrutiny by regulatory agencies globally that have, or may in the future have, regulatory authority over the Company and its business activities. This has resulted, or may in the future result, in regulatory agency investigations, litigation and subpoenas and costs related to each.
	Beginning in 2011, and from time to time thereafter, the Company has received subpoenas from the Securities and Exchange Commission and requests for information from the U.S. Department of Justice in connection with an investigation involving the Foreign Corrupt Practices Act and related laws. The investigation concerns an investment by a foreign sovereign wealth fund in some of the Och-Ziff funds in 2007 and investments by some of the funds, both directly and indirectly, in a number of companies in Africa. At this time, the Company is unable to determine how the investigation will be resolved and what impact, if any, it will have. An adverse outcome could have a material effect on the Company’s consolidated financial statements.
	On May 5, 2014, a purported class of shareholders filed a lawsuit against the Company in the U.S. District Court for the Southern District of New York (Menaldi v. Och-Ziff Capital Mgmt., et al.).  Daniel Och and Joel Frank are also named defendants.  The complaint asserts claims on behalf of all purchasers of Company securities from February 9, 2012 to April 25, 2014, and asserts claims under the Securities Exchange Act of 1934.  The complaint alleges, among other things, breaches of certain disclosure obligations with respect to matters under investigation by the U.S. Securities and Exchange Commission and the U.S. Department of Justice.  On May 30, 2014, a shareholder derivative action was filed against the Company in the Supreme Court of the State of New York, County of New York (Stokes v. Och, et al.).  On August 8, 2014, a second shareholder derivative action was filed against us in the United States District Court for the Southern District of New York (Jha v. Och, et al.). Each complaint asserts claims derivatively on behalf of the Company against all of the Company’s directors and alleges that the directors breached their fiduciary duties and other disclosure obligations with respect to the matters described above.
	The Company believes these cases are without merit and intends to defend them vigorously.
	Investment Commitments
	From time to time, certain funds consolidated by the Company may have commitments to fund investments. These commitments are funded through contributions from investors in those funds. The Company generally only manages these funds and is not an investor in the funds.
	The Company has committed to fund a portion of the operating budget for a joint venture. The amount of the commitment will be equal to the actual costs incurred in the projects the joint venture manages, as determined by the Company and its joint venture partner. The joint venture periodically returns substantially all of the cash that is contributed by the Company, as expenses incurred by the joint venture are generally reimbursed by the projects it manages.
	Certain of the Company’s executive managing directors, collectively, have capital commitments to a fund managed by the Company of up to $30.0 million. The Company has guaranteed these commitments in the event any executive managing director fails to fund any portion when called by the fund. The Company has historically not funded any of these commitments and does not expect to in the future, as these commitments are expected to be funded by the Company’s executive managing directors individually.
	Other Contingencies
	In the normal course of business, the Company enters into contracts that provide a variety of general indemnifications. Such contracts include those with certain service providers, brokers and trading counterparties. Any exposure to the Company under these arrangements could involve future claims that may be made against the Company. Currently, no such claims exist or are expected to arise and, accordingly, the Company has not accrued any liability in connection with such indemnifications.

Segment Reporting [Abstract]	'
Segment Information	'
	15		SEGMENT INFORMATION
	The Och-Ziff Funds segment is currently the Company’s only reportable segment and represents the Company’s core business, as substantially all of the Company’s operations are conducted through this segment. The Och-Ziff Funds segment provides asset management services to the Company’s multi-strategy, credit and equity funds, CLOs and other alternative investment vehicles.
	The Company’s Other Operations are primarily comprised of its real estate business, which provides asset management services to its real estate funds. The businesses included in the Company’s Other Operations do not meet the thresholds of reportable business segments under GAAP.
	In addition to analyzing the Company’s results on a GAAP basis, management also reviews its results on an “Economic Income” basis. Economic Income excludes the adjustments described below that are required for presentation of the Company’s results on a GAAP basis, but that management does not consider when evaluating operating performance in any given period. Management uses Economic Income as the basis on which it evaluates the Company’s financial performance and makes resource allocation and other operating decisions. Management considers it important that investors review the same operating information that it uses.
	Economic Income is a measure of pre-tax operating performance that excludes the following from the Company’s results on a GAAP basis:
	•	Income allocations to the Company’s executive managing directors and the Ziffs (until they exchanged their remaining interests during the 2014 second quarter) on their direct interests in the Och-Ziff Operating Group. Management reviews operating performance at the Och-Ziff Operating Group level, where substantially all of the Company’s operations are performed, prior to making any income allocations.
	•	Reorganization expenses related to the 2007 Offerings, equity-based compensation expenses and depreciation and amortization expenses, as management does not consider these non-cash expenses to be reflective of operating performance.
	•	Changes in the tax receivable agreement liability and net gains (losses) on investments in Och-Ziff funds, as management does not consider these to be reflective of operating performance.
	•	Amounts related to the consolidated Och-Ziff funds, including the related eliminations of management fees and incentive income, as management reviews the total amount of management fees and incentive income earned in relation to total assets under management and fund performance. The Company also defers the recognition of incentive income allocations from the consolidated Och-Ziff funds until all clawback contingencies are resolved, consistent with the revenue recognition policy for the funds the Company does not consolidate.
	In addition, expenses related to compensation and profit-sharing arrangements based on fund investment performance are recognized at the end of the relevant performance measurement period, as management reviews the total compensation expense related to these arrangements in relation to any incentive income earned by the relevant fund.
	Finally, management reviews Economic Income revenues by presenting management fees net of recurring placement and related service fees, rather than considering these fees an expense, and by excluding the impact of eliminations related to the consolidated Och-Ziff funds.
	Management does not regularly review assets by operating segment in assessing operating segment performance and the allocation of company resources; therefore, the Company does not present total assets by operating segment. All interest expense related to outstanding indebtedness is allocated to the Och-Ziff Funds segment.

	17		RESTATEMENTS
	As discussed in Note 2 to the Company’s consolidated financial statements included in its Annual Report, the Company restated the quarterly amounts previously reported in its 2013 first through third quarters Form 10-Qs due to material adjustments necessary to give effect to the consolidation of the Company’s CLOs. In addition, due to a change related to the accounting for previously deferred incentive income allocations from the consolidated Och-Ziff funds that remained subject to clawback, as well as the presentation of redeemable noncontrolling interests, the Company adjusted the prior period amounts presented throughout this quarterly report to conform to the current period presentation. See Note 2 to the Company’s consolidated financial statements included in its Annual Report for additional information.
	The tables below present the effect of these adjustments on the affected line items in the Company’s consolidated statement of comprehensive income as originally reported in the Company’s quarterly report on Form 10-Q for the three and nine months ended September 30, 2013. There were no changes to the previously reported net cash flows from operating, investing and financing activities resulting from these adjustments.

	These unaudited, interim, consolidated financial statements are prepared in accordance with GAAP as set forth in the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”), and should be read in conjunction with the audited consolidated financial statements included in the Company’s annual report on Form 10-K for the year ended December 31, 2013 (the “Annual Report”). In the opinion of management, all adjustments considered necessary for a fair presentation of the Company’s unaudited, interim, consolidated financial statements have been included and are of a normal and recurring nature. The results of operations presented for the interim periods are not necessarily indicative of the results that may be expected for any other interim period or for the entire year, primarily because of the majority of incentive income and discretionary cash bonuses being recorded in the fourth quarter each year. All significant intercompany transactions and balances have been eliminated in consolidation.
	As discussed in Note 17, the Company restated the quarterly amounts previously reported in its Form 10-Qs for the first through third quarters of 2013. See Note 17 for additional information.

	Recently Adopted Accounting Pronouncements
	None of the changes to GAAP that went into effect in the nine months ended September 30, 2014 has had a material effect on the Company’s consolidated financial statements.
	Future Adoption of Accounting Pronouncements
	In May 2014, the FASB issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers. ASU 2014-09 supersedes the revenue recognition requirements in ASC 605—Revenue Recognition and most industry-specific guidance throughout the Codification. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Entities are permitted to apply the guidance in ASU 2014-09 using one of the following methods: (1) full retrospective application to each prior period presented, or (2) modified retrospective application with a cumulative effect adjustment to opening retained earnings in the annual reporting period that includes that date of initial application. The requirements of ASU 2014-09 are effective for the Company beginning in the first quarter of 2017. The Company is currently evaluating the impact, if any, that these updates will have on its financial condition and results of operations.
	In August 2014, the FASB issued ASU 2014-13, Measuring the Financial Assets and the Financial Liabilities of a Consolidated Collateralized Financing Entity. ASU 2014-13 amends ASC 810—Consolidation to address the measurement difference that may occur between the fair value, as determined under GAAP, of the financial assets and financial liabilities of a consolidated collateralized financing entity, such as a CLO. The new guidance provides a measurement alternative which allows entities to measure both the financial assets and financial liabilities of the consolidated collateralized financing entity using the more observable of the fair value of the financial assets and the fair value of the financial liabilities. The requirements of ASU 2014-13 are effective for the Company beginning in the first quarter of 2016, with early adoption permitted in the first quarter of 2015. The Company is currently evaluating the impact that this update will have on its financial condition and results of operations.
	None of the other changes to GAAP that are not yet effective is expected to have a material effect on the Company's consolidated financial statements.
Fair Value Disclosure	'
	Fair value represents the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between market participants as of the measurement date (i.e., an exit price). Due to the inherent uncertainty of valuations of investments that are determined to be illiquid or do not have readily ascertainable fair values, the estimates of fair value may differ from the values ultimately realized, and those differences can be material.
	GAAP prioritizes the level of market price observability used in measuring assets and liabilities at fair value. Market price observability is impacted by a number of factors, including the type of assets and liabilities and the specific characteristics of the assets and liabilities. Assets and liabilities with readily available, actively quoted prices or for which fair value can be measured from actively-quoted prices generally will have a higher degree of market price observability and lesser degree of judgment used in measuring fair value.
	Assets and liabilities measured at fair value are classified into one of the following categories:
	•	Level I – Fair value is determined using quoted prices that are available in active markets for identical assets or liabilities. The types of assets and liabilities that would generally be included in this category are certain listed equities, U.S. Treasury obligations and certain listed derivatives.
	•	Level II – Fair value is determined using quotations received from dealers making a market for these assets or liabilities (“broker quotes”), valuations obtained from independent third-party pricing services, the use of models or other valuation methodologies based on pricing inputs that are either directly or indirectly market observable as of the measurement date. The types of assets and liabilities that would generally be included in this category are certain corporate bonds, certain credit default swap contracts, certain bank debt securities, certain commercial real estate debt, less liquid and restricted equity securities, forward contracts and certain over the-counter (“OTC”) derivatives.
	•	Level III – Fair value is determined using pricing inputs that are unobservable in the market and includes situations where there is little, if any, market activity for the asset or liability. The fair value of assets and liabilities in this category may require significant judgment or estimation in determining fair value of the assets or liabilities. The fair value of these assets and liabilities may be estimated using a combination of observed transaction prices, independent pricing services, relevant broker quotes, models or other valuation methodologies based on pricing inputs that are neither directly or indirectly market observable. The types of assets and liabilities that would generally be included in this category include real estate investments, equity and debt securities issued by private entities, limited partnerships, certain corporate bonds, certain credit default swap contracts, certain bank debt securities, certain commercial real estate debt, certain OTC derivatives, residential and commercial mortgage-backed securities, asset-backed securities, collateralized debt obligations, as well as the notes payable of consolidated CLOs.
	In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, an asset or liability’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. The assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability.
