Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Basis of Presentation	1. Organization and Basis of Presentation The Carlyle Group L.P., together with its consolidated subsidiaries, is one of the world’s largest global investment firms that originates, structures and acts as lead equity investor in management-led buyouts, strategic minority equity investments, equity private placements, consolidations and buildups, growth capital financings, real estate opportunities, bank loans, high-yield debt, distressed assets, mezzanine debt and other investment opportunities. The Carlyle Group L.P. is a Delaware limited partnership formed on July 18, 2011, which is managed and operated by its general partner, Carlyle Group Management L.L.C., which is in turn wholly-owned and controlled by Carlyle’s founders and other senior Carlyle professionals. Except as otherwise indicated by the context, references to the “Partnership” or “Carlyle” refer to The Carlyle Group L.P., together with its consolidated subsidiaries. Carlyle provides investment management services to, and has transactions with, various private equity funds, real estate funds, private credit funds, collateralized loan obligations (“CLOs”), and other investment products sponsored by the Partnership for the investment of client assets in the normal course of business. Carlyle typically serves as the general partner, investment manager or collateral manager, making day-to-day investment decisions concerning the assets of these products. Carlyle operates its business through four reportable segments: Corporate Private Equity, Real Assets, Global Credit, and Investment Solutions (see Note 14). Conversion On July 31, 2019, Carlyle announced its decision to convert The Carlyle Group L.P. from a Delaware limited partnership to a Delaware corporation named The Carlyle Group Inc. (the "Conversion"). The Conversion is expected to become effective on January 1, 2020. Carlyle also announced the termination of future obligations under the tax receivable agreement, whereby the Partnership will be obligated to pay cash payments aggregating to $1.50 per Carlyle Holdings partnership unit exchanged, payable in five annual installments of $0.30 per unit beginning in 2020. Based on the Carlyle Holdings partnership units outstanding as of September 30, 2019, the total cash payments would be approximately $344 million. Basis of Presentation The accompanying condensed consolidated financial statements include the accounts of the Partnership and its consolidated subsidiaries. In addition, certain Carlyle-affiliated funds, related co-investment entities, certain CLOs managed by the Partnership (collectively the “Consolidated Funds”) have been consolidated in the accompanying condensed consolidated financial statements pursuant to accounting principles generally accepted in the United States (“U.S. GAAP”), as described in Note 2. The consolidation of the Consolidated Funds generally has a gross-up effect on assets, liabilities and cash flows, and generally has no effect on the net income attributable to the Partnership. The economic ownership interests of the other investors in the Consolidated Funds are reflected as non-controlling interests in consolidated entities in the accompanying condensed consolidated financial statements (see Note 2). The accompanying condensed consolidated financial statements have been prepared in accordance with U.S. GAAP for interim financial information. These statements, including notes, have not been audited, exclude some of the disclosures required for annual financial statements, and should be read in conjunction with the audited consolidated financial statements included in the Partnership’s Annual Report on Form 10-K for the year ended December 31, 2018 filed with the Securities and Exchange Commission (“SEC”). 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. In the opinion of management, the condensed consolidated financial statements reflect all adjustments, consisting of normal recurring accruals, which are necessary for the fair presentation of the financial condition and results of operations for the interim periods presented.

2. Summary of Significant Accounting Policies

Principles of Consolidation

The Partnership consolidates all entities that it controls either through a majority voting interest or as the primary beneficiary of variable interest entities (“VIEs”).

The Partnership evaluates (1) whether it holds a variable interest in an entity, (2) whether the entity is a VIE, and (3) whether the Partnership’s involvement would make it the primary beneficiary. In evaluating whether the Partnership holds a variable interest, fees (including management fees, incentive fees and performance allocations) that are customary and commensurate with the level of services provided, and where the Partnership does not hold other economic interests in the entity that would absorb more than an insignificant amount of the expected losses or returns of the entity, are not considered

variable interests. The Partnership considers all economic interests, including indirect interests, to determine if a fee is considered a variable interest.

For those entities where the Partnership holds a variable interest, the Partnership determines whether each of these entities qualifies as a VIE and, if so, whether or not the Partnership is the primary beneficiary. The assessment of whether the entity is a VIE is generally performed qualitatively, which requires judgment. These judgments include: (a) determining whether the equity investment at risk is sufficient to permit the entity to finance its activities without additional subordinated financial support, (b) evaluating whether the equity holders, as a group, can make decisions that have a significant effect on the economic performance of the entity, (c) determining whether two or more parties' equity interests should be aggregated, and (d) determining whether the equity investors have proportionate voting rights to their obligations to absorb losses or rights to receive returns from an entity.

For entities that are determined to be VIEs, the Partnership consolidates those entities where it has concluded it is the primary beneficiary. The primary beneficiary is defined as the variable interest holder with (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. In evaluating whether the Partnership is the primary beneficiary, the Partnership evaluates its economic interests in the entity held either directly or indirectly by the Partnership.

As of September 30, 2019, assets and liabilities of the consolidated VIEs reflected in the unaudited condensed consolidated balance sheets were $4.7 billion and $4.5 billion, respectively. Except to the extent of the consolidated assets of the VIEs, the holders of the consolidated VIEs’ liabilities generally do not have recourse to the Partnership.

Substantially all of the Partnership’s Consolidated Funds are CLOs, which are VIEs that issue loans payable that are backed by diversified collateral asset portfolios consisting primarily of loans or structured debt. In exchange for managing the collateral for the CLOs, the Partnership earns investment management fees, including in some cases subordinated management fees and contingent incentive fees. In cases where the Partnership consolidates the CLOs (primarily because of a retained interest that is significant to the CLO), those management fees have been eliminated as intercompany transactions. As of September 30, 2019, the Partnership held $165.6 million of investments in these CLOs which represents its maximum risk of loss. The Partnership’s investments in these CLOs are generally subordinated to other interests in the entities and entitle the Partnership to receive a pro rata portion of the residual cash flows, if any, from the entities. Investors in the CLOs have no recourse against the Partnership for any losses sustained in the CLO structure.

Entities that do not qualify as VIEs are generally assessed for consolidation as voting interest entities. Under the voting interest entity model, the Partnership consolidates those entities it controls through a majority voting interest.

All significant inter-entity transactions and balances of entities consolidated have been eliminated.

Investments in Unconsolidated Variable Interest Entities

The Partnership holds variable interests in certain VIEs that are not consolidated because the Partnership is not the primary beneficiary, including its investments in certain CLOs and strategic investment in NGP Management Company, L.L.C. (“NGP Management” and, together with its affiliates, “NGP”). Refer to Note 4 for information on the strategic investment in NGP. The Partnership’s involvement with such entities is in the form of direct equity interests and fee arrangements. The maximum exposure to loss represents the loss of assets recognized by the Partnership relating to its variable interests in these unconsolidated entities. The assets recognized in the Partnership’s consolidated balance sheets related to the Partnership’s variable interests in these non-consolidated VIEs were as follows:



	As of
	September 30, 2019		December 31, 2018
	(Dollars in millions)
Investments	$	1,058.6	$	1,152.4
Performance allocations	162.8		121.2
Management fee arrangements	30.0		15.1
Total	$	1,251.4	$	1,288.7

These amounts represent the Partnership’s maximum exposure to loss related to the unconsolidated VIEs as of September 30, 2019 and December 31, 2018.

Basis of Accounting

The accompanying financial statements are prepared in accordance with U.S. GAAP. Management has determined that the Partnership’s Funds are investment companies under U.S. GAAP for the purposes of financial reporting. U.S. GAAP for an investment company requires investments to be recorded at estimated fair value and the unrealized gains and/or losses in an investment’s fair value are recognized on a current basis in the statements of operations. Additionally, the Funds do not consolidate their majority-owned and controlled investments (the “Portfolio Companies”). In the preparation of these unaudited condensed consolidated financial statements, the Partnership has retained the specialized accounting for the Funds.

All of the investments held and notes issued by the Consolidated Funds are presented at their estimated fair values in the Partnership’s condensed consolidated balance sheets. Interest and other income of the Consolidated Funds as well as interest expense and other expenses of the Consolidated Funds are included in the Partnership’s unaudited condensed consolidated statements of operations.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make assumptions and estimates that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Management’s estimates are based on historical experiences and other factors, including expectations of future events that management believes to be reasonable under the circumstances. It also requires management to exercise judgment in the process of applying the Partnership’s accounting policies. Assumptions and estimates regarding the valuation of investments and their resulting impact on performance allocations involve a higher degree of judgment and complexity and these assumptions and estimates may be significant to the consolidated financial statements and the resulting impact on performance allocations and incentive fees. Actual results could differ from these estimates and such differences could be material.

Business Combinations

The Partnership accounts for business combinations using the acquisition method of accounting, under which the purchase price of the acquisition is allocated to the assets acquired and liabilities assumed using the fair values determined by management as of the acquisition date. Contingent consideration obligations that are elements of consideration transferred are recognized as of the acquisition date as part of the fair value transferred in exchange for the acquired business. Acquisition-related costs incurred in connection with a business combination are expensed as incurred.

Revenue Recognition

The Partnership recognizes revenue in accordance with ASC 606, Revenue from Contracts with Customers. Revenue is recognized when the Partnership transfers promised goods or services to customers in an amount that reflects the consideration to which the Partnership expects to be entitled to in exchange for those goods or services. ASC 606 includes a five-step framework that requires an entity to: (i) identify the contract(s) with a customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations in the contract, and (v) recognize revenue when the entity satisfies a performance obligation.

The Partnership accounts for performance allocations that represent a performance-based capital allocation from fund limited partners to the Partnership (commonly known as “carried interest”, which comprises substantially all of the Partnership’s previously reported performance fee revenues) as earnings from financial assets within the scope of ASC 323, Investments - Equity Method and Joint Ventures, and therefore are not in the scope of ASC 606. In accordance with ASC 323, the Partnership records equity method income (losses) as a component of investment income based on the change in its proportionate claim on net assets of the investment fund, including performance allocations, assuming the investment fund was liquidated as of each reporting date pursuant to each fund’s governing agreements. See Note 4 for additional information on the components of investments and investment income. Performance fees that do not meet the definition of performance-based capital allocations are in the scope of ASC 606 and are included in incentive fees in the consolidated statements of operations.

While the determination of who is the customer in a contractual arrangement will be made on a contract-by-contract basis, the customer will generally be the investment fund for the Partnership’s significant management and advisory contracts. The customer determination impacts the Partnership’s analysis of the accounting for contract costs. Also, the recovery of certain costs incurred on behalf of Carlyle funds, primarily travel and entertainment costs, are presented gross in the unaudited condensed consolidated statements of operations, as the Partnership controls the inputs to its investment management performance obligation.

Fund Management Fees

The Partnership provides management services to funds in which it holds a general partner interest or has a management agreement. The Partnership considers the performance obligations in its contracts with its funds to be the promise to provide (or to arrange for third parties to provide) investment management services related to the management, policies and operations of the funds.

As it relates to the Partnership’s performance obligation to provide investment management services, the Partnership typically satisfies this performance obligation over time as the services are rendered, since the funds simultaneously receive and consume the benefits provided as the Partnership performs the service. The transaction price is the amount of consideration to which the Partnership expects to be entitled in exchange for transferring the promised services to the funds. Management fees earned from each investment management contract over the contract life represent variable consideration because the consideration the Partnership is entitled to varies based on fluctuations in the basis for the management fee, for example fund net asset value (“NAV”) or AUM. Given that the management fee basis is susceptible to market factors outside of the Partnership’s influence, management fees are constrained and, therefore, estimates of future period management fees are generally not included in the transaction price. Revenue recognized for the investment management services provided is generally the amount determined at the end of the period because that is when the uncertainty for that period is resolved.

For closed-end carry funds in the Corporate Private Equity, Real Assets and Global Credit segments, management fees generally range from 1.0% to 2.0% of commitments during the fund’s investment period based on limited partners’ capital commitments to the funds. Following the expiration or termination of the investment period, management fees generally are based on the lower of cost or fair value of invested capital and the rate charged may also be reduced to between 0.6% and 2.0%. For certain separately managed accounts and longer-dated carry funds, with expected terms greater than ten years, management fees generally range from 0.2% to 1.0% based on contributions for unrealized investments or the current value of the investment. The Partnership will receive management fees during a specified period of time, which is generally ten years from the initial closing date, or, in some instances, from the final closing date, but such termination date may be earlier in certain limited circumstances or later if extended for successive one-year periods, typically up to a maximum of two years. Depending upon the contracted terms of investment advisory or investment management and related agreements, these fees are generally called semi-annually in advance and are recognized as earned over the subsequent six month period. For certain longer-dated carry funds, management fees are called quarterly over the life of the funds.

Within the Global Credit segment, for CLOs and other structured products, management fees generally range from 0.4% to 0.5% based on the total par amounts of assets or the aggregate principal amount of the notes in the CLO and are due quarterly based on the terms and recognized over the respective period. Management fees for the CLOs and other structured products are governed by indentures and collateral management agreements. The Partnership will receive management fees for the CLOs until redemption of the securities issued by the CLOs, which is generally five to ten years after issuance. Management fees for the business development companies are due quarterly in arrears at annual rates that range from 1.25% of invested capital to 1.5% of gross assets, excluding cash and cash equivalents.

Management fees for the Partnership’s private equity and real estate carry fund vehicles in the Investment Solutions segment generally range from 0.25% to 1.0% of the vehicle’s capital commitments during the commitment fee period of the relevant fund or the weighted-average investment period of the underlying funds. Following the expiration of the commitment fee period or weighted-average investment period of such funds, the management fees generally range from 0.25% to 1.0% on (i) the lower of cost or fair value of the capital invested, (ii) the net asset value for unrealized investments, or (iii) the contributions for unrealized investments; however, certain separately managed accounts earn management fees at all times on contributions for unrealized investments or on the initial commitment amount. Management fees for the Investment Solutions carry fund vehicles are generally due quarterly and recognized over the related quarter.

As of September 30, 2019 and December 31, 2018, management fee receivables were $72.8 million and $76.2 million, respectively, and are included in due from affiliates and other receivables, net, in the unaudited condensed consolidated balance sheets.

The Partnership also provides transaction advisory and portfolio advisory services to the portfolio companies, and where covered by separate contractual agreements, recognizes fees for these services when the performance obligation has been satisfied and collection is reasonably assured. Transaction fees also include underwriting fees from the Partnership’s loan syndication and capital markets business, Carlyle Capital Solutions (“CCS”). Fund management fees include transaction and portfolio advisory fees of $9.9 million and $7.7 million for the three months ended September 30, 2019 and 2018, respectively, and $33.0 million and $21.3 million for the nine months ended September 30, 2019 and 2018, respectively, net of any offsets as defined in the respective partnership agreements.

Fund management fees exclude the reimbursement of any partnership expenses paid by the Partnership on behalf of the Carlyle funds pursuant to the limited partnership agreements, including amounts related to the pursuit of actual, proposed, or unconsummated investments, professional fees, expenses associated with the acquisition, holding and disposition of investments, and other fund administrative expenses. For the professional fees that the Partnership arranges for the investment funds, the Partnership concluded that the nature of its promise is to arrange for the services to be provided and it does not control the services provided by third parties before they are transferred to the customer. Therefore, the Partnership concluded it is acting in the capacity of an agent. Accordingly, the reimbursement for these professional fees paid on behalf of the investment funds is presented on a net basis in general, administrative and other expenses in the unaudited condensed consolidated statements of operations.

The Partnership also incurs certain costs, primarily employee travel and entertainment costs, employee compensation and systems costs, for which it receives reimbursement from the investment funds in connection with its performance obligation to provide investment and management services. For reimbursable travel, compensation and systems costs, the Partnership concluded it controls the services provided by its employees and the resources used to develop applicable systems before they are transferred to the customer and therefore is a principal. Accordingly, the reimbursement for these costs incurred by the Partnership to manage the fund limited partnerships are presented on a gross basis in interest and other income in the unaudited condensed consolidated statements of operations and the expense in general, administrative and other expenses or cash-based compensation and benefits expenses in the unaudited condensed consolidated statements of operations.

Incentive Fees

In connection with management contracts from certain of its Global Credit funds, the Partnership is also entitled to receive performance-based incentive fees when the return on assets under management exceeds certain benchmark returns or other performance targets. In such arrangements, incentive fees are recognized when the performance benchmark has been achieved. Incentive fees are variable consideration because they are contingent upon the investment vehicle achieving stipulated investment return hurdles. Investment returns are highly susceptible to market factors outside of the Partnership’s influence. Accordingly, incentive fees are constrained until the uncertainty is resolved. Estimates of future period incentive fees are generally not included in the transaction price because these estimates are constrained. The transaction price for incentive fees is generally the amount determined at the end of each accounting period to which they relate because that is when the uncertainty for that period is resolved, as these fees are not subject to clawback.

Investment Income (Loss), including Performance Allocations

Investment income (loss) represents the unrealized and realized gains and losses resulting from the Partnership’s equity method investments, including any associated general partner performance allocations, and other principal investments, including CLOs.

General partner performance allocations consist of the allocation of profits from certain of the funds to which the Partnership is entitled (commonly known as carried interest).

For closed-end carry funds in the Corporate Private Equity, Real Assets and Global Credit segments, the Partnership is generally entitled to a 20% allocation (or 10% to 20% on certain longer-dated carry funds, certain credit funds, up to 25% on certain Corporate Private Equity funds in the event performance benchmarks are achieved, and external co-investment vehicles, or approximately 2% to 10% for most of the Investment Solutions segment carry fund vehicles) of the net realized income or gain as a carried interest after returning the invested capital, the allocation of preferred returns of generally 7% to 9% (or 4% to 7% for certain longer-dated carry funds) and return of certain fund costs (generally subject to catch-up provisions as set forth in the fund limited partnership agreement). Carried interest is recognized upon appreciation of the funds’ investment values above certain return hurdles set forth in each respective partnership agreement. The Partnership recognizes revenues attributable to performance allocations based upon the amount that would be due pursuant to the fund partnership agreement at each period end as if the funds were terminated at that date. Accordingly, the amount recognized as investment income for performance allocations reflects the Partnership’s share of the gains and losses of the associated funds’ underlying investments measured at their then-current fair values relative to the fair values as of the end of the prior period. Because of the inherent uncertainty, these estimated values may differ significantly from the values that would have been used had a ready market for the investments existed, and it is reasonably possible that the difference could be material.

Carried interest is ultimately realized when: (i) an underlying investment is profitably disposed of, (ii) certain costs borne by the limited partner investors have been reimbursed, (iii) the fund’s cumulative returns are in excess of the preferred return and (iv) the Partnership has decided to collect carry rather than return additional capital to limited partner investors. Realized carried interest may be required to be returned by the Partnership in future periods if the funds’ investment values decline below

certain levels. When the fair value of a fund’s investments remains constant or falls below certain return hurdles, previously recognized performance allocations are reversed. In all cases, each fund is considered separately in this regard, and for a given fund, performance allocations can never be negative over the life of a fund. If upon a hypothetical liquidation of a fund’s investments at their then-current fair values, previously recognized and distributed carried interest would be required to be returned, a liability is established for the potential giveback obligation.

Principal investment income (loss) is realized when the Partnership redeems all or a portion of its investment or when the Partnership receives or is due cash income, such as dividends or distributions. Principal investment income (loss) also includes the Partnership’s allocation of earnings from its investment in Fortitude Re. As it relates to the Partnership’s investments in NGP (see Note 4), principal investment income includes the related amortization of the basis difference between the Partnership’s carrying value of its investment and the Partnership’s share of underlying net assets of the investee, as well as the compensation expense associated with compensatory arrangements provided by the Partnership to employees of its equity method investee. Unrealized principal investment income (loss) results from the Partnership's proportionate share of the investee's unrealized earnings, including changes in the fair value of the underlying investment, as well as the reversal of unrealized gain (loss) at the time an investment is realized.

Interest Income

Interest income is recognized when earned. For debt securities representing non-investment grade beneficial interests in securitizations, the effective yield is determined based on the estimated cash flows of the security. Changes in the effective yield of these securities due to changes in estimated cash flows are recognized on a prospective basis as adjustments to interest income in future periods. Interest income earned by the Partnership is included in interest and other income in the accompanying unaudited condensed consolidated statements of operations. Interest income of the Consolidated Funds was $49.8 million and $57.9 million for the three months ended September 30, 2019 and 2018, respectively, $144.5 million and $155.9 million for the nine months ended September 30, 2019 and 2018, respectively, and is included in interest and other income of Consolidated Funds in the accompanying unaudited condensed consolidated statements of operations.

Compensation and Benefits

Cash-based Compensation and Benefits – Cash-based compensation and benefits includes salaries, bonuses (discretionary awards and guaranteed amounts), performance payment arrangements and benefits paid and payable to Carlyle employees. Bonuses are accrued over the service period to which they relate.

Equity-Based Compensation – Compensation expense relating to the issuance of equity-based awards to Carlyle employees is measured at fair value on the grant date. In June 2018, the Partnership adopted ASU 2018-7, Improvements to Nonemployee Share-Based Payment Accounting, which aligned the accounting for non-employee equity-based awards with the accounting for employee equity-based awards, retroactive to January 1, 2018. The compensation expense for awards that vest over a future service period is recognized over the relevant service period on a straight-line basis. The compensation expense for awards that do not require future service is recognized immediately. Cash settled equity-based awards are classified as liabilities and are re-measured at the end of each reporting period. The compensation expense for awards that contain performance conditions is recognized when it is probable that the performance conditions will be achieved; in certain instances, such compensation expense may be recognized prior to the grant date of the award. The compensation expense for awards that contain market conditions is based on a grant-date fair value that factors in the probability that the market conditions will be achieved and is recognized over the requisite service period on a straight-line basis.

Equity-based awards issued to non-employees are generally recognized as general, administrative and other expenses, except to the extent they are recognized as part of the Partnership’s equity method earnings because they are issued to employees of equity method investees.

The Partnership recognizes equity-based award forfeitures in the period they occur as a reversal of previously recognized compensation expense. The reduction in compensation expense is determined based on the specific awards forfeited during that period. Furthermore, the Partnership recognizes all excess tax benefits and deficiencies as income tax benefit or expense in the unaudited condensed consolidated statement of operations.

Performance Allocations and Incentive Fee Related Compensation – A portion of the performance allocations and incentive fees earned is due to employees and advisors of the Partnership. These amounts are accounted for as compensation expense in conjunction with the recognition of the related performance allocations and incentive fee revenue and, until paid, are recognized as a component of the accrued compensation and benefits liability. Accordingly, upon a reversal of performance allocations or incentive fee revenue, the related compensation expense, if any, is also reversed. As of September 30, 2019 and December 31, 2018, the Partnership had recorded a liability of $2.0 billion and $1.8 billion, respectively, related to the portion

of accrued performance allocations and incentive fees due to employees and advisors, respectively, which was included in accrued compensation and benefits in the accompanying unaudited condensed consolidated balance sheets.

Income Taxes

Certain of the wholly-owned subsidiaries of the Partnership and the Carlyle Holdings partnerships are subject to federal, state, local and foreign corporate income taxes at the entity level and the related tax provision attributable to the Partnership’s share of this income is reflected in the unaudited condensed consolidated financial statements. Based on applicable federal, foreign, state and local tax laws, the Partnership records a provision for income taxes for certain entities. Tax positions taken by the Partnership are subject to periodic audit by U.S. federal, state, local and foreign taxing authorities.

On July 31, 2019, the Partnership announced its decision to convert the Carlyle Group L.P. from a Delaware limited partnership to a Delaware corporation named The Carlyle Group Inc.

The Partnership accounts for income taxes using the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future consequences of events that have been included in the financial statements or tax returns. Under this method, deferred tax assets and liabilities are determined based on the difference between the financial statement reporting and the tax basis of assets and liabilities using enacted tax rates in effect for the period in which the difference is expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in the period of the change in the provision for income taxes. Further, deferred tax assets are recognized for the expected realization of available net operating loss and tax credit carry forwards. A valuation allowance is recorded on the Partnership’s gross deferred tax assets when it is “more likely than not” that such asset will not be realized. When evaluating the realizability of the Partnership’s deferred tax assets, all evidence, both positive and negative, is evaluated. Items considered in this analysis include the ability to carry back losses, the reversal of temporary differences, tax planning strategies, and expectations of future earnings.

Under U.S. GAAP for income taxes, the amount of tax benefit to be recognized is the amount of benefit that is “more likely than not” to be sustained upon examination. The Partnership analyzes its tax filing positions in all of the U.S. federal, state, local and foreign tax jurisdictions where it is required to file income tax returns, as well as for all open tax years in these jurisdictions. If, based on this analysis, the Partnership determines that uncertainties in tax positions exist, a liability is established, which is included in accounts payable, accrued expenses and other liabilities in the unaudited condensed consolidated financial statements. The Partnership recognizes accrued interest and penalties related to unrecognized tax positions in the provision for income taxes. If recognized, the entire amount of unrecognized tax positions would be recorded as a reduction in the provision for income taxes.

Tax Receivable Agreement

Exchanges of Carlyle Holdings partnership units for the Partnership’s common units that are executed by the limited partners of the Carlyle Holdings partnerships result in transfers of and increases in the tax basis of the tangible and intangible assets of Carlyle Holdings, primarily attributable to a portion of the goodwill inherent in the business. These transfers and increases in tax basis will increase (for tax purposes) depreciation and amortization and therefore reduce the amount of tax that certain of the Partnership’s subsidiaries, including Carlyle Holdings I GP Inc., which are referred to as the “corporate taxpayers,” would otherwise be required to pay in the future. This increase in tax basis may also decrease gain (or increase loss) on future dispositions of certain capital assets to the extent tax basis is allocated to those capital assets. The Partnership has entered into a tax receivable agreement with the limited partners of the Carlyle Holdings partnerships whereby the corporate taxpayers have agreed to pay to the limited partners of the Carlyle Holdings partnerships involved in any exchange transaction 85% of the amount of cash tax savings, if any, in U.S. federal, state and local income tax or foreign or franchise tax that the corporate taxpayers realize as a result of these increases in tax basis and, in limited cases, transfers or prior increases in tax basis. The corporate taxpayers expect to benefit from the remaining 15% of cash tax savings, if any, in income tax they realize. Payments under the tax receivable agreement will be based on the tax reporting positions that the Partnership will determine. The corporate taxpayers will not be reimbursed for any payments previously made under the tax receivable agreement if a tax basis increase is successfully challenged by the Internal Revenue Service.

The Partnership records an increase in deferred tax assets for the estimated income tax effects of the increases in tax basis based on enacted federal and state tax rates at the date of the exchange. To the extent that the Partnership estimates that the corporate taxpayers will not realize the full benefit represented by the deferred tax asset, based on an analysis that will consider, among other things, its expectation of future earnings, the Partnership will reduce the deferred tax asset with a valuation allowance and will assess the probability that the related liability owed under the tax receivable agreement will be paid. The Partnership records 85% of the estimated realizable tax benefit (which is the recorded deferred tax asset less any recorded

valuation allowance) as an increase to the liability due under the tax receivable agreement, which is included in due to affiliates in the accompanying condensed consolidated financial statements. The remaining 15% of the estimated realizable tax benefit is initially recorded as an increase to the Partnership’s partners’ capital.

All of the effects to the deferred tax asset of changes in any of the Partnership’s estimates after the tax year of the exchange will be reflected in the provision for income taxes. Similarly, the effect of subsequent changes in the enacted tax rates will be reflected in the provision for income taxes.

On July 31, 2019, the Partnership announced the termination of future obligations under the tax receivable agreement.

Non-controlling Interests

Non-controlling interests in consolidated entities represent the component of equity in consolidated entities held by third-party investors. These interests are adjusted for general partner allocations which occur during the reporting period. Any change in ownership of a subsidiary while the controlling financial interest is retained is accounted for as an equity transaction between the controlling and non-controlling interests. Transaction costs incurred in connection with such changes in ownership of a subsidiary are recorded as a direct charge to partners’ capital.

Non-controlling interests in Carlyle Holdings relate to the ownership interests of the other limited partners of the Carlyle Holdings partnerships. The Partnership, through wholly-owned subsidiaries, is the sole general partner of Carlyle Holdings. Accordingly, the Partnership consolidates Carlyle Holdings into its consolidated financial statements, and the other ownership interests in Carlyle Holdings are reflected as non-controlling interests in the Partnership’s unaudited condensed consolidated financial statements. Any change to the Partnership’s ownership interest in Carlyle Holdings while it retains the controlling financial interest in Carlyle Holdings is accounted for as a transaction within partners’ capital as a reallocation of ownership interests in Carlyle Holdings.

Earnings Per Common Unit

The Partnership computes earnings per common unit in accordance with ASC 260, Earnings Per Share. Basic earnings per common unit is calculated by dividing net income (loss) attributable to the common units of the Partnership by the weighted-average number of common units outstanding for the period. Diluted earnings per common unit reflects the assumed conversion of all dilutive securities. Net income (loss) attributable to the common units excludes net income (loss) and dividends attributable to any participating securities under the two-class method of ASC 260.

Investments

Investments include (i) the Partnership’s ownership interests (typically general partner interests) in the Funds, (ii) strategic investments made by the Partnership (both of which are accounted for as equity method investments), (iii) the investments held by the Consolidated Funds (which are presented at fair value in the Partnership’s unaudited condensed consolidated financial statements), and (iv) certain credit-oriented investments, including investments in the CLOs (which are accounted for as trading securities).

The valuation procedures utilized for investments of the Funds vary depending on the nature of the investment. The fair value of investments in publicly-traded securities is based on the closing price of the security with adjustments to reflect appropriate discounts if the securities are subject to restrictions.

The fair value of non-equity securities or other investments, which may include instruments that are not listed on an exchange, considers, among other factors, external pricing sources, such as dealer quotes or independent pricing services, recent trading activity or other information that, in the opinion of the Partnership, may not have been reflected in pricing obtained from external sources.

When valuing private securities or assets without readily determinable market prices, the Partnership gives consideration to operating results, financial condition, economic and/or market events, recent sales prices and other pertinent information. These valuation procedures may vary by investment, but include such techniques as comparable public market valuation, comparable acquisition valuation and discounted cash flow analysis. Because of the inherent uncertainty, these estimated values may differ significantly from the values that would have been used had a ready market for the investments existed, and it is reasonably possible that the difference could be material. Furthermore, there is no assurance that, upon liquidation, the Partnership will realize the values presented herein.

Upon the sale of a security or other investment, the realized net gain or loss is computed on a weighted average cost basis, with the exception of the investments held by the CLOs, which compute the realized net gain or loss on a first in, first out basis. Securities transactions are recorded on a trade date basis.

Principal Equity Method Investments

The Partnership accounts for all investments in which it has or is otherwise presumed to have significant influence, including investments in the unconsolidated Funds and strategic investments, using the equity method of accounting. The carrying value of equity method investments is determined based on amounts invested by the Partnership, adjusted for the equity in earnings or losses of the investee (including performance allocations) allocated based on the respective partnership agreement, less distributions received. The Partnership evaluates its equity method investments for impairment whenever events or changes in circumstances indicate that the carrying amounts of such investments may not be recoverable.

Cash and Cash Equivalents

Cash and cash equivalents include cash held at banks and cash held for distributions, including investments with original maturities of less than three months when purchased.

Cash and Cash Equivalents Held at Consolidated Funds

Cash and cash equivalents held at Consolidated Funds consists of cash and cash equivalents held by the Consolidated Funds, which, although not legally restricted, is not available to fund the general liquidity needs of the Partnership.

Restricted Cash

Restricted cash primarily represents cash held by the Partnership’s foreign subsidiaries due to certain government regulatory capital requirements as well as certain amounts held on behalf of Carlyle funds.

Corporate Treasury Investments

Corporate treasury investments represent investments in U.S. Treasury and government agency obligations, commercial paper, certificates of deposit, other investment grade securities and other investments with original maturities of greater than three months when purchased. These investments are accounted for as trading securities in which changes in the fair value of each investment are recorded through investment income (loss). Any interest earned on debt investments is recorded through interest and other income.

Derivative Instruments

The Partnership uses derivative instruments primarily to reduce its exposure to changes in foreign currency exchange rates. Derivative instruments are recognized at fair value in the unaudited condensed consolidated balance sheets with changes in fair value recognized in the unaudited condensed consolidated statements of operations for all derivatives not designated as hedging instruments.

Securities Sold Under Agreements to Repurchase

As it relates to certain European CLOs sponsored by the Partnership, securities sold under agreements to repurchase (“repurchase agreements”) are accounted for as collateralized financing transactions. The Partnership provides securities to counterparties to collateralize amounts borrowed under repurchase agreements on terms that permit the counterparties to repledge or resell the securities to others. As of September 30, 2019, $40.6 million of securities were transferred to counterparties under repurchase agreements and are included within investments in the condensed consolidated balance sheets. Cash received under repurchase agreements is recognized as a liability within debt obligations in the condensed consolidated balance sheets. Interest expense is recognized on an effective yield basis and is included within interest expense in the condensed consolidated statements of operations. See Note 5 for additional information.

Fixed Assets

Fixed assets consist of furniture, fixtures and equipment, leasehold improvements, and computer hardware and software and are stated at cost, less accumulated depreciation and amortization. Depreciation is recognized on a straight-line method over the assets’ estimated useful lives, which for leasehold improvements are the lesser of the lease terms or the life of the asset,

and three to seven years for other fixed assets. Fixed assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable.

Leases

On January 1, 2019, the Partnership adopted ASU 2016-2, Leases (Topic 842) under the modified retrospective method. ASU 2016-2, and related amendments, requires lessees to recognize virtually all of their leases on the balance sheet by recording right-of-use assets and lease liabilities. The lease liability is measured at the present value of lease payments and the right-of-use asset is based on the lease liability value, subject to adjustments for deferred rent, lease incentives, unamortized initial direct costs, or impairment. As of December 31, 2018, there was $65.2 million of deferred rent and lease incentives that was reclassified from accounts payable, accrued expenses and other liabilities into right-of-use assets upon the adoption of ASU 2016-2. Leases can be classified as either operating leases or finance leases. Operating leases will result in straight-line lease expense, while finance leases will result in front-loaded expense. The adoption of this guidance did not have a material impact on operating results. The Partnership elected the transition option provided by the FASB, which allows entities to not apply ASC 842 in the comparative periods presented in the financial statements in the year of adoption. The Partnership also elected to use the practical expedients available under the transition provisions under which the Partnership did not need to reassess whether an arrangement is or contains a lease, lease classification, and the accounting for initial direct costs.

The Partnership recognizes a lease liability and right-of-use asset in the condensed consolidated balance sheet for contracts that it determines are leases or contain a lease. The Partnership’s leases primarily consist of operating leases for office space in various countries around the world. The Partnership also has operating leases for office equipment and vehicles, which are not significant. The Partnership does not separate non-lease components from lease components for its office space and equipment operating leases and instead accounts for each separate lease component and its associated non-lease component as a single lease component. Right-of-use assets represent the Partnership’s right to use an underlying asset for the lease term and lease liabilities represent the Partnership’s obligation to make lease payments arising from the leases. The Partnership’s right-of-use assets and lease liabilities are recognized at lease commencement based on the present value of lease payments over the lease term. Lease right-of-use assets include initial direct costs incurred by the Partnership and are presented net of deferred rent and lease incentives. Absent an implicit interest rate in the lease, the Partnership uses its incremental borrowing rate, adjusted for the effects of collateralization, based on the information available at commencement in determining the present value of lease payments. The Partnership’s lease terms may include options to extend or terminate the lease when it is reasonably certain that the Partnership will exercise those options. Lease expense for lease payments is recognized on a straight-line basis over the lease term.

The Partnership does not recognize a lease liability or right-of-use asset on the balance sheet for short-term leases. Instead, the Partnership recognizes short-term lease payments as an expense on a straight-line basis over the lease term. A short-term lease is defined as a lease that, at the commencement date, has a lease term of 12 months or less and does not include an option to purchase the underlying asset that the lessee is reasonably certain to exercise. When determining whether a lease qualifies as a short-term lease, the Partnership evaluates the lease term and the purchase option in the same manner as all other leases.

Intangible Assets and Goodwill

The Partnership’s intangible assets consist of acquired contractual rights to earn future fee income, including management and advisory fees, customer relationships, and acquired trademarks. Finite-lived intangible assets are amortized over their estimated useful lives, which range from four to ten years, and are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. Intangible asset amortization expense was $3.9 million and $2.6 million during the three months ended September 30, 2019 and 2018, respectively, and $11.6 million and $7.9 million during the nine months ended September 30, 2019 and 2018, respectively, and is included in general, administrative, and other expenses in the unaudited condensed consolidated statements of operations.

Goodwill represents the excess of cost over the identifiable net assets of businesses acquired and is recorded in the functional currency of the acquired entity. Goodwill is recognized as an asset and is reviewed for impairment annually as of October 1st and between annual tests when events and circumstances indicate that impairment may have occurred.

Deferred Revenue

Deferred revenue represents management fees and other revenue received prior to the balance sheet date, which has not yet been earned. The increase in the deferred revenue balance for the nine months ended September 30, 2019 was primarily

driven by cash payments received in advance of the Partnership satisfying its performance obligations, partially offset by revenues that were included in the deferred revenue balance at the beginning of the period.

Accumulated Other Comprehensive Income (Loss)

The Partnership’s accumulated other comprehensive income (loss) is comprised of foreign currency translation adjustments and gains and losses on defined benefit plans sponsored by AlpInvest. The components of accumulated other comprehensive income (loss) as of September 30, 2019 and December 31, 2018 were as follows:



	As of
	September 30, 2019			December 31, 2018
	(Dollars in millions)
Currency translation adjustments	$	(92.2	)	$	(79.7	)
Unrealized losses on defined benefit plans	(3.5		)	(4.6		)
Fortitude Re available-for-sale securities	6.6			1.0
Total	$	(89.1	)	$	(83.3	)

Foreign Currency Translation

Non-U.S. dollar denominated assets and liabilities are translated at period-end rates of exchange, and the unaudited condensed consolidated statements of operations are translated at rates of exchange in effect throughout the period. Foreign currency gains (losses) resulting from transactions outside of the functional currency of an entity of $0.7 million and $3.2 million for the three months ended September 30, 2019 and 2018, respectively, and $(5.0) million and $1.6 million for the nine months ended September 30, 2019 and 2018, respectively, are included in general, administrative and other expenses in the unaudited condensed consolidated statements of operations.

Recent Accounting Pronouncements

In August 2018, the SEC adopted amendments to certain disclosure requirements in Securities Act Release No. 33-10532, Disclosure Update and Simplification. The amendments became effective on November 5, 2018. Among the amendments is the requirement to present the changes in shareholders’ equity in the interim financial statements (either in a separate statement or footnote) in quarterly reports on Form 10-Q. The Partnership included a separate statement of changes in partners’ capital in these condensed consolidated financial statements.

Recently Issued Accounting Standards Adopted as of January 1, 2019

In February 2018, the FASB issued ASU 2018-2, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. ASU 2018-2 allows a reclassification from accumulated other comprehensive income to partners’ capital for stranded effects resulting from the Tax Cuts and Jobs Act. The guidance was effective for the Partnership on January 1, 2019 and the Partnership adopted this guidance on that date. The impact of this guidance was not material to the Partnership.

In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815) - Targeted Improvements to Accounting for Hedging Activities. ASU 2017-12, among other things, permits hedge accounting for risk components in hedging relationships to now involve nonfinancial risk components and requires an entity to present the earnings effect of the hedging instrument in the same income statement line item in which the earnings effect of the hedge item is reported. The guidance was effective for the Partnership on January 1, 2019 and requires cash flow hedges and net investment hedges existing at the date of adoption to apply a cumulative effect adjustment to eliminate the measurement of ineffectiveness to accumulated other comprehensive income with a corresponding adjustment to the opening balance of partners’ capital as of the beginning of the fiscal year that an entity adopts the guidance. The amended presentation and disclosure guidance is required only prospectively. The Partnership adopted this guidance on January 1, 2019 and the impact was not material.

Recently Issued Accounting Standards Effective on January 1, 2020

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820) - Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement. ASU 2018-13 eliminates, adds and modifies certain disclosure requirements for fair value measurements. This guidance is effective for the Partnership on January 1, 2020 and early adoption is permitted. The Partnership is currently assessing the potential impact of this guidance to the fair value disclosures.

In January 2017, the FASB issued ASU 2017-4, Intangibles - Goodwill and Other (Topic 350) - Simplifying the Test for Goodwill Impairment. ASU 2017-04 simplifies an entity’s annual goodwill test for impairment by eliminating the requirement to calculate the implied fair value of goodwill, and instead an entity should compare the fair value of a reporting unit with its carrying amount. The impairment charge will then be the amount by which the carrying amount exceeds the reporting unit’s fair value. An entity would still have the option to perform a qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. The guidance is effective for the Partnership on January 1, 2020 and requires the guidance to be applied using a prospective transition method. Early adoption is permitted. The Partnership does not expect the impact of this guidance to be material.

In June 2016, the FASB issued ASU 2016-13, Accounting for Financial Instruments - Credit Losses (Topic 326). ASU 2016-13 requires an organization to measure all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Currently, GAAP requires an “incurred loss” methodology that delays recognition until it is probable a loss has been incurred. Under the new standard, the allowance for credit losses must be deducted from the amortized cost of the financial asset to present the net amount expected to be collected. The income statement will reflect the measurement of credit losses for newly recognized financial assets as well as the expected increases or decreases of expected credit losses that have taken place during the period. This provision of the guidance requires a modified retrospective transition method and will result in a cumulative-effect adjustment in retained earnings upon adoption. This guidance is effective for the Partnership on January 1, 2020 and early adoption is permitted. The Partnership has identified all of the material financial assets that are within the scope of this guidance and does not expect the impact of this guidance to be material.

Fair Value Disclosures [Abstract]

Fair Value Measurement

3. Fair Value Measurement

The fair value measurement accounting guidance establishes a hierarchical disclosure framework which ranks the observability of market price inputs used in measuring financial instruments at fair value. The observability of inputs is impacted by a number of factors, including the type of financial instrument, the characteristics specific to the financial instrument and the state of the marketplace, including the existence and transparency of transactions between market participants. Financial instruments with readily available quoted prices, or for which fair value can be measured from quoted prices in active markets, will generally have a higher degree of market price observability and a lesser degree of judgment applied in determining fair value.

Financial instruments measured and reported at fair value are classified and disclosed based on the observability of inputs used in the determination of fair values, as follows:

Level I – inputs to the valuation methodology are quoted prices available in active markets for identical instruments as of the reporting date. The types of financial instruments in this category include unrestricted securities, such as equities and derivatives, listed in active markets. The Partnership does not adjust the quoted price for these instruments, even in situations where the Partnership holds a large position and a sale could reasonably impact the quoted price.

Level II – inputs to the valuation methodology are other than quoted prices in active markets, which are either directly or indirectly observable as of the reporting date. The types of financial instruments in this category include less liquid and restricted securities listed in active markets, securities traded in other than active markets, government and agency securities, and certain over-the-counter derivatives where the fair value is based on observable inputs.

Level III – inputs to the valuation methodology are unobservable and significant to overall fair value measurement. The inputs into the determination of fair value require significant management judgment or estimation. The types of financial instruments in this category include investments in privately-held entities, non-investment grade residual interests in securitizations, collateralized loan obligations, and certain over-the-counter derivatives where fair value is based on unobservable inputs.

In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, the determination of which category within the fair value hierarchy is appropriate for any given financial instrument is based on the lowest level of input that is significant to the fair value measurement. The Partnership’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the financial instrument.

In certain cases, debt and equity securities are valued on the basis of prices from an orderly transaction between market participants provided by reputable dealers or pricing services. In determining the value of a particular investment, pricing services may use certain information with respect to transactions in such investments, quotations from dealers, pricing matrices, market transactions in comparable investments and various relationships between investments.

The following table summarizes the Partnership’s assets and liabilities measured at fair value on a recurring basis by the above fair value hierarchy levels as of September 30, 2019:

There were no transfers from Level II to Level I during the nine months ended September 30, 2019 and 2018.

Investment professionals with responsibility for the underlying investments are responsible for preparing the investment valuations pursuant to the policies, methodologies and templates prepared by the Partnership’s valuation group, which is a team made up of dedicated valuation professionals reporting to the Partnership’s chief accounting officer. The valuation group is responsible for maintaining the Partnership’s valuation policy and related guidance, templates and systems that are designed to be consistent with the guidance found in ASC 820, Fair Value Measurement. These valuations, inputs and preliminary conclusions are reviewed by the fund accounting teams. The valuations are then reviewed and approved by the respective fund valuation

subcommittees, which include the respective fund head(s), segment head, chief financial officer and chief accounting officer, as well as members of the valuation group. The valuation group compiles the aggregate results and significant matters and presents them for review and approval by the global valuation committee, which includes the Partnership’s co-executive chairmen of the board, chairman emeritus, co-chief executive officers, chief risk officer, chief financial officer, chief accounting officer, co-chief investment officers and the business segment heads, and observed by the chief compliance officer, the director of internal audit, the Partnership’s audit committee and others. Additionally, each quarter a sample of valuations is reviewed by external valuation firms.

In the absence of observable market prices, the Partnership values its investments using valuation methodologies applied on a consistent basis. For some investments little market activity may exist. Management’s determination of fair value is then based on the best information available in the circumstances and may incorporate management’s own assumptions and involve a significant degree of judgment, taking into consideration a combination of internal and external factors, including the appropriate risk adjustments for non-performance and liquidity risks. Investments for which market prices are not observable include private investments in the equity of operating companies and real estate properties, and certain debt positions. The valuation technique for each of these investments is described below:

Private Equity and Real Estate Investments – The fair values of private equity investments are determined by reference to projected net earnings, earnings before interest, taxes, depreciation and amortization (“EBITDA”), the discounted cash flow method, public market or private transactions, valuations for comparable companies or sales of comparable assets, and other measures which, in many cases, are unaudited at the time received. The methods used to estimate the fair value of real estate investments include the discounted cash flow method and/or capitalization rate (“cap rate”) analysis. Valuations may be derived by reference to observable valuation measures for comparable companies or transactions (e.g., applying a key performance metric of the investment such as EBITDA or net operating income to a relevant valuation multiple or cap rate observed in the range of comparable companies or transactions), adjusted by management for differences between the investment and the referenced comparables, and in some instances by reference to option pricing models or other similar models. Adjustments to observable valuation measures are frequently made upon the initial investment to calibrate the initial investment valuation to industry observable inputs. Such adjustments are made to align the investment to observable industry inputs for differences in size, profitability, projected growth rates, geography and capital structure if applicable. The adjustments are reviewed with each subsequent valuation to assess how the investment has evolved relative to the observable inputs. Additionally, the investment may be subject to certain specific risks and/or development milestones which are also taken into account in the valuation assessment. Option pricing models and similar tools do not currently drive a significant portion of private equity or real estate valuations and are used primarily to value warrants, derivatives, certain restrictions and other atypical investment instruments.

Credit-Oriented Investments – The fair values of credit-oriented investments (including corporate treasury investments) are generally determined on the basis of prices between market participants provided by reputable dealers or pricing services. In determining the value of a particular investment, pricing services may use certain information with respect to transactions in such investments, quotations from dealers, pricing matrices, market transactions in comparable investments and various relationships between investments. Specifically, for investments in distressed debt and corporate loans and bonds, the fair values are generally determined by valuations of comparable investments. In some instances, the Partnership may utilize other valuation techniques, including the discounted cash flow method.

CLO Investments and CLO Loans Payable – The Partnership measures the financial liabilities of its consolidated CLOs based on the fair value of the financial assets of its consolidated CLOs, as the Partnership believes the fair value of the financial assets are more observable. The fair values of the CLO loan and bond assets are primarily based on quotations from reputable dealers or relevant pricing services. In situations where valuation quotations are unavailable, the assets are valued based on similar securities, market index changes, and other factors. The Partnership performs certain procedures to ensure the reliability of the quotations from pricing services. Generally, the loan and bond assets of the CLOs are not publicly traded and are classified as Level III. The fair values of the CLO structured asset positions are determined based on both discounted cash flow analyses and third party quotes. Those analyses consider the position size, liquidity, current financial condition of the CLOs, the third party financing environment, reinvestment rates, recovery lags, discount rates and default forecasts and are compared to broker quotations from market makers and third party dealers.

The Partnership measures the CLO loans payable held by third party beneficial interest holders on the basis of the fair value of the financial assets of the CLO and the beneficial interests held by the Partnership. The Partnership continues to measure the CLO loans payable that it holds at fair value based on both discounted cash flow analyses and third-party quotes, as described above.

Fund Investments – The Partnership’s investments in external funds are valued based on its proportionate share of the net assets provided by the third party general partners of the underlying fund partnerships based on the most recent available information which typically has a lag of up to 90 days. The terms of the investments generally preclude the ability to redeem the investment. Distributions from these investments will be received as the underlying assets in the funds are liquidated, the timing of which cannot be readily determined.

The changes in financial instruments measured at fair value for which the Partnership has used Level III inputs to determine fair value are as follows (Dollars in millions):

(1) As a result of the consolidation of one CLO during the nine months ended September 30, 2019, the investment that the Partnership held in that CLO is now eliminated in consolidation and no longer included in investments in CLOs and other. Additionally, two CLOs were deconsolidated during the nine months ended September 30, 2019 and as a result the investments that the Partnership held in those CLOs are no longer eliminated in consolidation and are now included in investments in CLOs and other.

Strategic Investment in Fortitude Re (f/k/a DSA Re)

On November 13, 2018, the Partnership acquired a 19.9% interest in Fortitude Group Holdings, LLC (“Fortitude Holdings”), a wholly owned subsidiary of American International Group, Inc. (“AIG”) (“the Transaction”). Fortitude Holdings owns 100% of the outstanding common shares of Fortitude Reinsurance Company Ltd., a Bermuda domiciled reinsurer (“Fortitude Re”, f/k/a “DSA Re”) established to reinsure a portfolio of AIG’s legacy life, annuity and property and casualty liabilities. Fortitude Re had approximately $35 billion in reserves as of December 31, 2018.

Pursuant to the Membership Interest Purchase Agreement, the Partnership entered into a strategic asset management relationship with Fortitude Re pursuant to which Fortitude Re, together with certain AIG-affiliated ceding companies it has reinsured, committed to allocate assets in asset management strategies and vehicles of the Partnership and its affiliates. If Fortitude Re, together with AIG and its affiliates, fails to allocate an agreed upon amount of assets to the Partnership’s asset management strategies and vehicles within 30 to 36 months of the closing of the transaction, the Partnership may be entitled to certain payments from AIG based on the commitment shortfall and assumed customary fee rates.

The Partnership paid $381 million in cash at closing (the “Initial Purchase Price”) and expects to pay up to $95 million in additional deferred consideration following December 31, 2023. If Fortitude Re is unable to distribute a planned non-pro rata dividend to AIG by May 2020, then the Initial Purchase Price may be adjusted upward by up to $100 million to account for the increased value of Fortitude Re’s equity. AIG also agreed to a post-closing purchase price adjustment pursuant to which AIG will pay affiliates of the Partnership in respect of certain adverse reserve development in Fortitude Re’s property and casualty insurance business, based on an agreed methodology, that occur on or prior to December 31, 2023, up to the value of the Partnership’s investment. The Partnership incurred approximately $17.9 million in transaction costs, which are included in the carrying value of the investment.

In connection with the Transaction, the Partnership also entered into an operating agreement that governs its rights and obligations as an equity holder of Fortitude Re and entitles the Partnership to customary minority protections contingent upon the Partnership maintaining agreed upon ownership percentages of Fortitude Re.

The Partnership’s investment is accounted for under the equity method of accounting and the investment is included in the Global Credit segment. Separately, income from the assets managed by the Partnership is included in the segment of the relevant investment fund. The Partnership’s net investment earnings (loss) from its investment are included in principal investment income in the unaudited condensed consolidated statements of operations.

As of September 30, 2019 and December 31, 2018, the Partnership’s investment in Fortitude Re is $1,285.1 million and $460.2 million, respectively. The Partnership’s earnings from its investment for the three and nine months ended September 30, 2019 were $281.6 million and $808.9 million, respectively, which represents 19.9% of Fortitude Re’s estimated net income for the respective periods. These amounts are inclusive of $213.5 million and $673.7 million, respectively, of unrealized gains related to the change in fair value of embedded derivatives related to certain reinsurance contracts included in Fortitude Re’s U.S. GAAP financial statements. Modified coinsurance is subject to the general accounting principles for hedging, specifically the guidance originally issued as Derivatives Implementation Group Issue No. B36: Embedded Derivatives: Modified Coinsurance Agreements and Debt Instruments That Incorporate Credit Risk Exposures That Are Unrelated or Only Partially Related to the Creditworthiness of the Obligor under Those Instruments (“DIG B36”).

Management fee-related revenues from NGP Management are primarily driven by NGP XII, NGP XI and NGP X during the three and nine months ended September 30, 2019 and 2018.

The Partnership records investment income (loss) for its equity income allocation from NGP management fee-related revenues and also records its share of any allocated expenses from NGP Management, expenses associated with the compensatory elements of the strategic investment, and the amortization of the basis differences related to the definite-lived identifiable intangible assets of NGP Management. The net investment income (loss) recognized in the Partnership’s unaudited condensed consolidated statements of operations for the three and nine months ended September 30, 2019 and 2018 were as follows:

The Partnership’s investment in the general partners of the NGP Carry Funds entitle it to 47.5% of the performance allocations received by certain current and future NGP fund general partners. The Partnership records its equity income allocation from NGP performance allocations in principal investment income from equity method investments rather than performance allocations. The Partnership recognized net investment earnings (losses) related to these performance allocations in its unaudited condensed consolidated statements of operations of $(81.6) million and $10.2 million for the three months ended September 30, 2019 and 2018, respectively, and $(111.5) million and $62.1 million for the nine months ended September 30, 2019 and 2018, respectively.

Senior Credit Facility

On February 11, 2019, the Partnership entered into an amendment and restatement of its senior credit facility. In connection with this amendment and restatement, the capacity under the revolving credit facility was increased to $775.0 million from $750.0 million, the term was extended to February 11, 2024, and the $25.0 million term loan was repaid. Principal amounts outstanding under the amended and restated revolving credit facility accrue interest, at the option of the borrowers, either (a) at an alternate base rate plus an applicable margin not to exceed 0.50% per annum, or (b) at LIBOR plus an applicable margin not to exceed 1.50% per annum (at September 30, 2019, the interest rate was 3.27%). There was no amount outstanding under the revolving credit facility at September 30, 2019. Interest expense under the senior credit facility was not significant for the three and nine months ended September 30, 2019 and 2018. The fair value of the outstanding balances of the term loan and revolving credit facility at September 30, 2019 and December 31, 2018 approximated par value based on current market rates for similar debt instruments and are classified as Level III within the fair value hierarchy.

Global Credit Revolving Credit Facility

On December 17, 2018, certain subsidiaries of the Partnership established a $250.0 million revolving line of credit, primarily intended to support certain lending activities within the Global Credit segment. The credit facility includes a $125.0 million line of credit with a one-year term, and a $125.0 million line of credit with a three-year term. Principal amounts outstanding under the facility accrue interest, at the option of the borrowers, either (a) at an alternate base rate plus an applicable margin not to exceed 1.00%, or (b) at the Eurocurrency rate plus an applicable margin, not to exceed 2.00%.

During the three and nine months ended September 30, 2019, the Partnership borrowed $25.3 million and $42.3 million, respectively, and repaid $0 million and $17.0 million, respectively, under the credit facility. As of September 30, 2019, there was $25.3 million outstanding under this facility, which was repaid in October. Interest expense was not significant for the three and nine months ended September 30, 2019.

CLO Borrowings

For certain of the Partnership’s CLOs, the Partnership finances a portion of its investment in the CLOs through the proceeds received from term loans and other financing arrangements with financial institutions. The Partnership’s outstanding CLO borrowings consist of the following (Dollars in millions):



Formation Date	Borrowing Outstanding September 30, 2019		Borrowing Outstanding December 31, 2018		Maturity Date (1)	Interest Rate as of September 30, 2019

The CLO term loans are secured by the Partnership’s investments in the respective CLO, have a general unsecured interest in the Carlyle entity that manages the CLO, and generally do not have recourse to any other Carlyle entity. Interest expense on these term loans was not significant for the three and nine months ended September 30, 2019 and 2018. The fair value of the outstanding balance of the CLO term loans at September 30, 2019 approximated par value based on current market rates for similar debt instruments. These CLO term loans are classified as Level III within the fair value hierarchy.

European CLO Financing - February 28, 2017

On February 28, 2017, a subsidiary of the Partnership entered into a financing agreement with several financial institutions under which these financial institutions have provided a €67.1 million term loan ($73.2 million at September 30, 2019) to the Partnership. This term loan is secured by the Partnership’s investments in the retained notes in certain European CLOs that were formed in 2014 and 2015. This term loan will mature on the earlier of November 17, 2031 or the date that the certain European CLO retained notes have been redeemed. The Partnership may prepay the term loan in whole or in part at any time after the third anniversary of the date of issuance without penalty. Prepayment of the term loan within the first three years will incur a penalty based on the prepayment amount. Interest on this term loan accrues at EURIBOR plus applicable margins (2.33% at September 30, 2019).

Master Credit Agreement - Term Loans

In January 2017, the Partnership entered into a master credit agreement with a financial institution under which the financial institution expects to provide term loans to the Partnership for the purchase of eligible interests in CLOs. This agreement will terminate in January 2020. Any term loan to be issued under this master credit agreement will be secured by the Partnership’s investment in the respective CLO as well as any senior management fee and subordinated management fee payable by each CLO. Any term loan bears interest at LIBOR plus a weighted average spread over LIBOR on the CLO notes and an applicable margin. Interest is due quarterly. CLO Indentures for the respective CLO borrowings entered on November 30, 2017 and after provide for an alternative rate framework determined at the Partnership's discretion upon a trigger event of LIBOR.

CLO Repurchase Agreements

On February 5, 2019, the Partnership entered into a €100.0 million master credit facility agreement (the “CLO Financing Facility”) to finance a portion of the risk retention investments in certain European CLOs managed by the Partnership. Subject to the terms and conditions of the CLO Financing Facility, the Partnership and the counterparty may enter into repurchase agreements on such terms agreed upon by the parties. Each transaction entered into under the CLO Financing Facility will bear interest at a rate based on the weighted average effective interest rate of each class of securities that have been sold plus a spread to be agreed upon by the parties. As of September 30, 2019, €64.8 million of the CLO Financing Facility remained available.

Each transaction entered into under the CLO Financing Facility provides for payment netting and, in the case of a default or similar event with respect to the counterparty to the CLO Financing Facility, provides for netting across transactions. Generally, upon a counterparty default, the Partnership can terminate all transactions under the CLO Financing Facility and offset amounts it owes in respect of any one transaction against collateral, if any, or other amounts it has received in respect of any other transactions under the CLO Financing Facility; provided, however, that in the case of certain defaults, the Partnership may only be able to terminate and offset solely with respect to the transaction affected by the default. During the term of a transaction entered into under the CLO Financing Facility, the Partnership will deliver cash or additional securities acceptable to the counterparty if the securities sold are in default. Upon termination of a transaction, the Partnership will repurchase the previously sold securities from the counterparty at a previously determined repurchase price. The CLO Financing Facility may be terminated at any time upon certain defaults or circumstances agreed upon by the parties.

The repurchase agreements may result in credit exposure in the event the counterparty to the transaction is unable to fulfill its contractual obligations. The Partnership minimizes the credit risk associated with these activities by monitoring counterparty credit exposure and collateral values. Other than margin requirements, the Partnership is not subject to additional terms or contingencies which would expose the Partnership to additional obligations based upon the performance of the securities pledged as collateral.

Senior Notes

Certain indirect subsidiaries of the the Partnership have issued long term borrowings in the form of senior notes, on which interest is payable semi-annually in arrears. The following table provides information regarding these senior notes (Dollars in millions):



							Interest Expense

(2) Issued in January 2013 at 99.966% of par.

(3) Issued $400.0 million in aggregate principal at 99.583% of par in March 2013. An additional $200.0 million in aggregate principal was issued at 104.315% of par in March 2014, and is treated as a single class with the outstanding $400.0 million in senior notes previously issued.

(4) Issued in September 2018 at 99.914% of par.

(5) Issued in September 2019 at 99.841% of par.

(6) In September 2018, the Partnership completed a tender offer to re-purchase $250.0 million in aggregate principal amount of the 3.875% senior notes. As a result of this repurchase, the Partnership recognized $6.9 million of costs in interest expense and $0.9 million of costs in general, administrative and other expenses upon early extinguishment of the debt.

The issuers may redeem the senior notes, in whole at any time or in part from time to time, at a price equal to the greater of (i) 100% of the principal amount of the notes being redeemed and (ii) the sum of the present values of the remaining scheduled payments of principal and interest on any notes being redeemed discounted to the redemption date on a semiannual basis at the Treasury Rate plus 40 basis points (30 basis points in the case of the 3.875% and 3.500% senior notes), plus in each case accrued and unpaid interest on the principal amounts being redeemed.

Promissory Notes

Promissory Note Due January 1, 2022

On January 1, 2016, the Partnership issued a $120.0 million promissory note to Barclays Natural Resource Investments, a division of Barclays Bank PLC (“BNRI”) as part of the Partnership's strategic investment in NGP. Interest on the promissory note accrued at the three month LIBOR plus 2.50%. In September 2018, the Partnership prepaid the $108.8 million outstanding promissory note, plus $1.2 million of accrued and unpaid interest. Interest expense on the promissory note was not significant for the nine months ended September 30, 2018.

Promissory Notes Due July 15, 2019

In June 2017, as part of the settlement with investors in two commodities investment vehicles managed by an affiliate of the Partnership (disclosed in Note 7), the Partnership issued a series of promissory notes, aggregating to $53.9 million, to the investors of these commodities investment vehicles. Interest on these promissory notes accrued at the three month LIBOR plus 2%. These promissory notes matured on July 15, 2019 and were fully repaid as of that date. Interest expense on these promissory notes was not significant for the three and nine months ended September 30, 2019 and 2018. The fair value of the outstanding balance of these promissory notes at December 31, 2018 approximated par value based on current market rates for similar debt instruments and is classified as Level III within the fair value hierarchy.

Debt Covenants

The Partnership is subject to various financial covenants under its loan agreements including, among other items, maintenance of a minimum amount of management fee-earning assets. The Partnership is also subject to various non-financial

covenants under its loan agreements and the indentures governing its senior notes. The Partnership was in compliance with all financial and non-financial covenants under its various loan agreements as of September 30, 2019.

Loans Payable of Consolidated Funds

Loans payable of Consolidated Funds primarily represent amounts due to holders of debt securities issued by the CLOs. Several of the CLOs issued preferred shares representing the most subordinated interest, however these tranches are mandatorily redeemable upon the maturity dates of the senior secured loans payable, and as a result have been classified as liabilities and are included in loans payable of Consolidated Funds in the unaudited condensed consolidated balance sheets.

As of September 30, 2019 and December 31, 2018, the following borrowings were outstanding, which includes preferred shares classified as liabilities (Dollars in millions):



	As of September 30, 2019
	Borrowing Outstanding		Fair Value		Weighted Average Interest Rate			Weighted Average Remaining Maturity in Years
Senior secured notes	$	4,129.4	$	4,049.4	1.92	%		11.03
Subordinated notes, preferred shares and other	142.3		182.0		N/A		(1)	11.16
Total	$	4,271.7	$	4,231.4



	As of December 31, 2018
	Borrowing Outstanding		Fair Value		Weighted Average Interest Rate			Weighted Average Remaining Maturity in Years
Senior secured notes	$	4,723.4	$	4,607.2	1.94	%		10.70
Subordinated notes, preferred shares and other	178.5		232.9		N/A		(1)	9.95
Total	$	4,901.9	$	4,840.1


(1)	The subordinated notes and preferred shares do not have contractual interest rates, but instead receive distributions from the excess cash flows of the CLOs.

Loans payable of the 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 consisted of cash and cash equivalents, corporate loans, corporate bonds and other securities. As of September 30, 2019 and December 31, 2018, the fair value of the CLO assets was $4.6 billion and $5.5 billion, respectively.

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

7. Commitments and Contingencies

Capital Commitments

The Partnership and its unconsolidated affiliates have unfunded commitments to entities within the following segments as of September 30, 2019 (Dollars in millions):



	Unfunded Commitments
Corporate Private Equity	$	2,427.0
Real Assets	975.9
Global Credit	432.0
Investment Solutions	107.5
Total	$	3,942.4

Of the $3.9 billion of unfunded commitments, approximately $3.4 billion is subscribed individually by senior Carlyle professionals, advisors and other professionals, with the balance funded directly by the Partnership. In addition to these unfunded commitments, the Partnership may from time to time exercise its right to purchase additional interests in its investment funds that become available in the ordinary course of their operations.

Guaranteed Loans

On September 3, 2019, the Partnership entered into an agreement with a financial institution pursuant to which the Partnership is the guarantor on loans made to eligible employees investing in Carlyle sponsored funds (the “Program”). The Program has an initial period of one year, renewed annually, and accrues interest at either the WSJ Prime Rate minus 1.00% floating or the 12MAT Index plus 2.00% floating, in either case with a floor rate of 3.50% (versus actual rates of 4.00% and 4.33%, respectively, as of September 30, 2019). The aggregate Program limit of all loans is $100.0 million, and is collateralized by each borrower’s interest in the Carlyle sponsored funds. As of September 30, 2019, approximately $9.0 million was outstanding under the Program and payable by the employees. The Partnership has not funded any amounts under the guarantee to date, and believes the likelihood of any material funding under this guarantee to be remote. The fair value of the guarantee is not significant to the unaudited condensed consolidated financial statements.

The Partnership is party to an agreement with a financial institution pursuant to which the Partnership is the guarantor on a credit facility for eligible employees investing in Carlyle sponsored funds. This credit facility, which was replaced by the Program, renewed on an annual basis, allowed for annual incremental borrowings up to an aggregate of $11.3 million, and accrued interest at the lower of the prime rate, as defined, or three-month LIBOR plus 3%, reset quarterly. Subsequent to September 3, 2019, no incremental borrowings are allowed under the facility, and the remaining balance was substantially transferred to the Program. As of September 30, 2019 and December 31, 2018, approximately $2.4 million and $10.3 million, respectively, was outstanding under the credit facility and payable by the employees. The amount funded by the Partnership under this guarantee was not material.

Certain consolidated subsidiaries of the Partnership are the guarantor of revolving credit facilities for certain funds in the Investment Solutions segment. The guarantee is limited to the lesser of the total amount drawn under the credit facilities or the net asset value of the guarantor subsidiaries, which is approximately $16.5 million as of September 30, 2019. The outstanding balances are secured by uncalled capital commitments from the underlying funds and the Partnership believes the likelihood of any material funding under this guarantee to be remote.

Contingent Obligations (Giveback)

A liability for potential repayment of previously received performance allocations of $63.2 million at September 30, 2019 is shown as accrued giveback obligations in the unaudited condensed consolidated balance sheets, representing the giveback obligation that would need to be paid if the funds were liquidated at their current fair values at September 30, 2019. However, the ultimate giveback obligation, if any, generally is not paid until the end of a fund’s life or earlier if the giveback becomes fixed and early payment is agreed upon by the fund's partners (see Note 2). The Partnership has recorded $1.4 million of unbilled receivables from former and current employees and senior Carlyle professionals as of September 30, 2019 and December 31, 2018, related to giveback obligations, which are included in due from affiliates and other receivables, net in the accompanying unaudited condensed consolidated balance sheets. The receivables are collateralized by investments made by individual senior Carlyle professionals and employees in Carlyle-sponsored funds. In addition, $176.4 million and $176.1 million have been withheld from distributions of carried interest to senior Carlyle professionals and employees for potential giveback obligations as of September 30, 2019 and December 31, 2018, respectively. Such amounts are held on behalf of the respective current and former Carlyle employees to satisfy any givebacks they may owe and are held by entities not included in the accompanying condensed consolidated balance sheets. Current and former senior Carlyle professionals and employees are personally responsible for their giveback obligations. As of September 30, 2019, approximately $36.0 million of the Partnership's accrued giveback obligation is the responsibility of various current and former senior Carlyle professionals and other limited partners of the Carlyle Holdings partnerships, and the net accrued giveback obligation attributable to Carlyle Holdings is $27.2 million.

If, at September 30, 2019, all of the investments held by the Partnership’s Funds were deemed worthless, a possibility that management views as remote, the amount of realized and distributed carried interest subject to potential giveback would be $0.4 billion, on an after-tax basis where applicable.

Leases

The Partnership’s leases primarily consist of operating leases for office space in various countries around the world, including its headquarters in Washington, D.C. These leases have remaining lease terms of 1 year to 15 years, some of which include options to extend for up to 5 years and some of which include an option to terminate the leases within 1 year. The Partnership also has operating leases for office equipment and vehicles, which are not significant.

In June 2018, the Partnership entered into an amended non-cancelable lease agreement expiring on March 31, 2030 for its Washington, D.C. office. In connection with the amended lease, the Partnership exercised an option to terminate its office lease in Arlington, Virginia at the end of 2019. The Partnership will be relocating one of its New York City offices in late 2020 to new office space in Midtown New York. The new lease was signed in July 2018 and expires in 2036. In connection with this new lease, the Partnership incurred a charge of $63.5 million (including transaction costs) during the third quarter of 2018 related to the assignment of an existing office lease in New York City. The charge is expected to be paid over approximately 15 years beginning in 2021. This charge (excluding $3.5 million of transaction costs paid) was accounted for as a lease incentive, and is included in accounts payable, accrued expenses and other liabilities in the accompanying unaudited condensed consolidated balance sheets, since the lease has not yet commenced.

The following table summarizes the Partnership’s lease cost, cash flows and other supplemental information related to its operating leases (Dollars in millions):



	Three Months Ended September 30,			Nine Months Ended September 30,

Legal Matters

In the ordinary course of business, the Partnership is a party to litigation, investigations, inquiries, employment-related matters, disputes and other potential claims. Certain of these matters are described below. The Partnership is not currently able to estimate the reasonably possible amount of loss or range of loss, in excess of amounts accrued, for the matters that have not been resolved. The Partnership does not believe it is probable that the outcome of any existing litigation, investigations, disputes or other potential claims will materially affect the Partnership or these financial statements in excess of amounts accrued. The Partnership believes that the matters described below are without merit.

Along with many other companies and individuals in the financial sector, the Partnership and Carlyle Mezzanine Partners, L.P. (“CMP”) are named as defendants in Foy v. Austin Capital, a case filed in June 2009 in state court in New Mexico, which purports to be a qui tam suit on behalf of the State of New Mexico under the state Fraud Against Taxpayers Act (“FATA”). The suit alleges that investment decisions by New Mexico public investment funds were improperly influenced by campaign contributions and payments to politically connected placement agents. The plaintiffs seek, among other things, actual damages for lost income, rescission of the investment transactions described in the complaint and disgorgement of all fees received. In September 2017, the Court dismissed the lawsuit and the plaintiffs then filed an appeal seeking to reverse that decision. That appeal is pending. The Attorney General may also separately pursue its own recovery from defendants in the action.

Carlyle Capital Corporation Limited (“CCC”) was a fund sponsored by the Partnership that invested in AAA-rated residential mortgage backed securities on a highly leveraged basis. In March of 2008, amidst turmoil throughout the mortgage markets and money markets, CCC filed for insolvency protection in Guernsey. The Guernsey liquidators who took control of CCC in March 2008 filed a suit on July 7, 2010 against the Partnership, certain of its affiliates and the former directors of CCC in the Royal Court of Guernsey seeking more than $1.0 billion in damages in a case styled Carlyle Capital Corporation Limited v. Conway et al. On September 4, 2017, the Royal Court of Guernsey ruled that the Partnership and Directors of CCC acted reasonably and appropriately in the management and governance of CCC and that none of the Partnership, its affiliates or former directors of CCC had any liability. In December 2017, the plaintiff filed a notice of appeal of the trial court decision. A hearing before the Guernsey appellate court took place from October 8 through October 18, 2018. On April 12, 2019 the Guernsey Court of Appeal dismissed the appeal and affirmed the trial court’s decision. On July 31, 2019, the plaintiffs filed a notice of appeal with the Judicial Committee of the Privy Council. To date, the Partnership has received approximately £23.3 million ($28.6 million as of September 30, 2019) from the plaintiff as a deposit towards their obligation to reimburse the Partnership for legal fees and expenses incurred to defend against the claims. The Partnership has not recognized income in respect of the reimbursement as of September 30, 2019, as such amount is subject to adjustment pending a final determination of the correct reimbursement amount.

A Luxembourg subsidiary of CEREP I, a real estate fund, has been involved since 2010 in a tax dispute with the French authorities relating to whether gain from the sale of an investment was taxable in France. In April 2015, the French tax court issued an opinion in this matter adverse to CEREP I, holding the Luxembourg subsidiary of CEREP I liable for approximately €105 million (including interest accrued since the beginning of the tax dispute). CEREP I paid approximately €30 million of the tax obligations and the Partnership paid the remaining approximately €75 million in its capacity as a guarantor. The Partnership appealed the decision of the French tax court. In December 2017, the French appellate court reversed the earlier tax court opinion and awarded the Partnership a refund of the full €105 million of tax and penalties (inclusive of amounts paid

by CEREP I) and awarded interest on the refund of €12.5 million, before tax. The French government appealed the decision. In July 2019, the parties agreed to settle this matter by reducing the tax claim to €37.1 million of French tax and interest. The remaining €80.5 million will be retained by the Partnership and CEREP I. Accordingly, the Partnership recognized $71.5 million in principal investment income in the three months ended June 30, 2019.

The Partnership currently is and expects to continue to be, from time to time, subject to examinations, formal and informal inquiries and investigations by various U.S. and non-U.S. governmental and regulatory agencies, including but not limited to, the SEC, Department of Justice, state attorneys general, FINRA, National Futures Association and the U.K. Financial Conduct Authority. The Partnership routinely cooperates with such examinations, inquiries and investigations, and they may result in the commencement of civil, criminal, or administrative or other proceedings against the Partnership or its personnel.

During 2017, the Partnership entered into settlement and purchase agreements with investors in a hedge fund and two structured finance vehicles managed by Vermillion related to investments of approximately $400 million in petroleum commodities that the Partnership believes were misappropriated by third parties outside the U.S. In total, the Partnership paid $265 million ($165 million of which was paid in 2017 with the remaining $100 million paid in 2016) to fully resolve all claims related to these matters, and issued promissory notes in aggregate amount of $54 million to repurchase the investors' interests in the two structured finance vehicles. In connection with these settlements, the Partnership acquired certain rights to recoveries from certain marine cargo insurance policies and is continuing to undertake efforts to obtain reimbursement for the misappropriation of petroleum. During the fourth quarter of 2018, the Partnership reached an agreement with the primary underwriters in the marine cargo insurance policies for $55 million, of which the Partnership recognized approximately $32 million in insurance proceeds during the year ended December 31, 2018, with the remaining proceeds to be distributed to former investors. Although additional recovery efforts continue, there is no assurance that the Partnership will be successful in any of these efforts and the Partnership will not recognize any amounts in respect of such recoveries until such amounts are probable of payment.

It is not possible to predict the ultimate outcome of all pending investigations and legal proceedings and employment-related matters, and some of the matters discussed above involve claims for potentially large and/or indeterminate amounts of damages. Based on information known by management, management does not believe that as of the date of this filing the final resolutions of the matters above will have a material effect upon the Partnership’s unaudited condensed consolidated financial statements. However, given the potentially large and/or indeterminate amounts of damages sought in certain of these matters and the inherent unpredictability of investigations and litigations, it is possible that an adverse outcome in certain matters could, from time to time, have a material effect on the Partnership's financial results in any particular period.

The Partnership accrues an estimated loss contingency liability when it is probable that such a liability has been incurred and the amount of the loss can be reasonably estimated. As of September 30, 2019, the Partnership had recorded liabilities aggregating to approximately $35 million for litigation-related contingencies, regulatory examinations and inquiries, and other matters. The Partnership evaluates its outstanding legal and regulatory proceedings and other matters each quarter to assess its loss contingency accruals, and makes adjustments in such accruals, upward or downward, as appropriate, based on management's best judgment after consultation with counsel. There is no assurance that the Partnership's accruals for loss contingencies will not need to be adjusted in the future or that, in light of the uncertainties involved in such matters, the ultimate resolution of these matters will not significantly exceed the accruals that the Partnership has recorded.

Indemnifications

In the normal course of business, the Partnership and its subsidiaries enter into contracts that contain a variety of representations and warranties and provide general indemnifications. The Partnership’s maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Partnership that have not yet occurred. However, based on experience, the Partnership believes the risk of material loss to be remote.

Risks and Uncertainties

Carlyle’s funds seek investment opportunities that offer the possibility of attaining substantial capital appreciation. Certain events particular to each industry in which the underlying investees conduct their operations, as well as general economic conditions, may have a significant negative impact on the Partnership’s investments and profitability. Such events are beyond the Partnership’s control, and the likelihood that they may occur and the effect on the Partnership cannot be predicted.

Furthermore, certain of the funds’ investments are made in private companies and there are generally no public markets for the underlying securities at the current time. The funds’ ability to liquidate their publicly-traded investments are often subject to limitations, including discounts that may be required to be taken on quoted prices due to the number of shares being sold. The funds’ ability to liquidate their investments and realize value is subject to significant limitations and uncertainties, including among others currency fluctuations and natural disasters.

The Partnership and the funds make investments outside of the United States. Investments outside the United States may be subject to less developed bankruptcy, corporate, partnership and other laws (which may have the effect of disregarding or otherwise circumventing the limited liability structures potentially causing the actions or liabilities of one fund or a portfolio company to adversely impact the Partnership or an unrelated fund or portfolio company). Non-U.S. investments are subject to the same risks associated with the Partnership’s U.S. investments as well as additional risks, such as fluctuations in foreign currency exchange rates, unexpected changes in regulatory requirements, heightened risk of political and economic instability, difficulties in managing non-U.S. investments, potentially adverse tax consequences and the burden of complying with a wide variety of foreign laws.

Furthermore, Carlyle is exposed to economic risk concentrations related to certain large investments as well as concentrations of investments in certain industries and geographies.

Additionally, the Partnership encounters credit risk. Credit risk is the risk of default by a counterparty in the Partnership’s investments in debt securities, loans, leases and derivatives that result from a borrower’s, lessee’s or derivative counterparty’s inability or unwillingness to make required or expected payments.

The Partnership considers cash, cash equivalents, securities, receivables, equity method investments, accounts payable, accrued expenses, other liabilities, loans, senior notes, assets and liabilities of Consolidated Funds and contingent and other consideration for acquisitions to be its financial instruments. Except for the senior notes, the carrying amounts reported in the unaudited condensed consolidated balance sheets for these financial instruments equal or closely approximate their fair values. The fair value of the senior notes is disclosed in Note 5.

Due from Affiliates and Other Receivables, Net

The Partnership had the following due from affiliates and other receivables at September 30, 2019 and December 31, 2018:



	As of
	September 30, 2019		December 31, 2018
	(Dollars in millions)
Accrued incentive fees	$	7.9	$	7.1
Unbilled receivable for giveback obligations from current and former employees	1.4		1.4

Management fee, reimbursable expenses and other receivables from unconsolidated funds and affiliates, net	217.3		418.2
Total	$	246.4	$	441.1

Notes receivable represent loans that the Partnership has provided to certain unconsolidated funds to meet short-term obligations to purchase investments. Reimbursable expenses and other receivables from certain of the unconsolidated funds and portfolio companies relate to management fees receivable from limited partners, advisory fees receivable and expenses paid on behalf of these entities. These costs represent costs related to the pursuit of actual or proposed investments, professional fees and expenses associated with the acquisition, holding and disposition of the investments. The affiliates are obligated at the discretion of the Partnership to reimburse the expenses. Based on management’s determination, the Partnership accrues and charges interest on amounts due from affiliate accounts at interest rates ranging up to 6.96% as of September 30, 2019. The accrued and charged interest to the affiliates was not significant for any period presented.

These receivables are assessed regularly for collectability and amounts determined to be uncollectible are charged directly to general, administrative and other expenses in the condensed consolidated statements of operations. A corresponding allowance for doubtful accounts is recorded and such amounts were not significant for any period presented.

Due to Affiliates

The Partnership had the following due to affiliates balances at September 30, 2019 and December 31, 2018:



	As of
	September 30, 2019		December 31, 2018
	(Dollars in millions)
Due to non-consolidated affiliates	$	40.6	$	27.6
Amounts owed under the tax receivable agreement	107.1		101.9
Other	34.5		44.5
Total	$	182.2	$	174.0

The Partnership has recorded obligations for amounts due to certain of its affiliates. The Partnership periodically offsets expenses it has paid on behalf of its affiliates against these obligations. The amount owed under the tax receivable agreement is related primarily to the acquisition by the Partnership of Carlyle Holdings partnership units in June 2015 and March 2014, respectively, the exchange in May 2012 by CalPERS of its Carlyle Holdings partnership units for Partnership common units, as well as certain unit exchanges by senior Carlyle professionals which began in the second quarter of 2017 (see Note 12).

Other Related Party Transactions

In the normal course of business, the Partnership has made use of aircraft owned by entities controlled by senior Carlyle professionals. The senior Carlyle professionals paid for their purchases of aircraft and bear all operating, personnel and maintenance costs associated with their operation for personal use. Payment by the Partnership for the business use of these aircraft by senior Carlyle professionals and other employees, which is made at market rates, totaled $2.1 million and $1.6 million for the three months ended September 30, 2019 and 2018, respectively, and $5.6 million and $5.1 million for the nine months ended September 30, 2019 and 2018, respectively. These fees are included in general, administrative, and other expenses in the unaudited condensed consolidated statements of operations.

Senior Carlyle professionals and employees are permitted to participate in co-investment entities that invest in Carlyle funds or alongside Carlyle funds. In many cases, participation is limited by law to individuals who qualify under applicable legal requirements. These co-investment entities generally do not require senior Carlyle professionals and employees to pay management fees or performance allocations, however, Carlyle professionals and employees are required to pay their portion of partnership expenses.

Carried interest income from the funds can be distributed to senior Carlyle professionals and employees on a current basis, but is subject to repayment by the subsidiary of the Partnership that acts as general partner of the fund in the event that certain specified return thresholds are not ultimately achieved. The senior Carlyle professionals and certain other investment professionals have personally guaranteed, subject to certain limitations, the obligation of these subsidiaries in respect of this general partner obligation. Such guarantees are several and not joint and are limited to a particular individual’s distributions received.

The Partnership does business with some of its portfolio companies; all such arrangements are on a negotiated basis.

Substantially all revenue is earned from affiliates of Carlyle.

Weighted-average common units outstanding	105,560,193	346,930,017	102,936,949	112,851,327

The Partnership applies the treasury stock method to determine the dilutive weighted-average common units represented by the unvested deferred restricted common units. Also included in the determination of dilutive weighted-average common units are issuable and contingently issuable Carlyle Holdings partnership units and common units associated with the Partnership’s acquisitions, strategic investments in NGP and performance-vesting deferred restricted common units.

The Partnership applies the “if-converted” method to the vested Carlyle Holdings partnership units to determine the dilutive weighted-average common units outstanding. The Partnership applies the treasury stock method to the unvested Carlyle Holdings partnership units and the “if-converted” method on the resulting number of additional Carlyle Holdings partnership units to determine the dilutive weighted-average common units represented by the unvested Carlyle Holdings partnership units.

In computing the dilutive effect that the exchange of Carlyle Holdings partnership units would have on earnings per common unit, the Partnership considered that net income available to holders of common units would increase due to the elimination of non-controlling interests in Carlyle Holdings (including any tax impact). Based on these calculations, 229,954,310 of vested Carlyle Holdings partnership units and 7,568 of unvested Carlyle Holdings partnership units for the three months ended September 30, 2019, 230,504,999 of vested Carlyle Holdings partnership units and 3,560 of unvested Carlyle Holdings partnership units for the nine months ended September 30, 2019, and 229,942,607 of vested Carlyle Holdings partnership units and 2,852,616 of unvested Carlyle Holdings partnership units for the nine months ended September 30, 2018 were antidilutive, and therefore have been excluded.

Further, based on these calculations, 232,303,828 of vested Carlyle Holdings partnership units and 11,976 of unvested Carlyle Holdings partnership units for the three months ended September 30, 2018 were dilutive. As a result, net income of non-controlling interests in Carlyle Holdings associated with the assumed exchange of $22.5 million for the three months ended September 30, 2018 has been included in net income attributable to The Carlyle Group L.P. for purposes of the dilutive earnings per common unit calculation.

Preferred Unit Issuance and Redemption

On September 13, 2017, the Partnership issued 16,000,000 of 5.875% Series A Preferred Units (the “Preferred Units”) for gross proceeds of $400.0 million, or $387.5 million, net of issuance costs and expenses.

Distributions on the Preferred Units were payable quarterly on March 15, June 15, September 15, and December 15 of each year, beginning on December 15, 2017, when, as and if declared by the Board of Directors of the general partner of the Partnership, at a rate per annum of 5.875%. Distributions on the Preferred Units were discretionary and non-cumulative.

On September 5, 2019, the Partnership issued a redemption notice pursuant to the tax redemption provisions of the Preferred Units and redeemed them in full on October 7, 2019 at a price of $25.339757 per unit, which is equal to $25.25 per Preferred Unit plus declared and unpaid distributions to, but excluding, the redemption date. As the redemption is not revocable, the Partnership has recorded a liability of approximately $405.4 million, which is reflected in redeemed Series A preferred units on the unaudited condensed consolidated balance sheet as of September 30, 2019.

Unit Repurchase Program

In December 2018, the Board of Directors of the general partner of the Partnership authorized the repurchase of up to $200.0 million of common units and/or Carlyle Holdings units, inclusive of amounts remaining as originally authorized in February 2016. Under this new unit repurchase program, which became effective January 1, 2019, units may be repurchased from time to time in open market transactions, in privately negotiated transactions or otherwise. The Partnership expects that the majority of repurchases under this program will be done via open market and brokered transactions. The timing and actual number of common units and/or Carlyle Holdings units repurchased will depend on a variety of factors, including legal requirements, price and economic and market conditions. This unit repurchase program may be suspended or discontinued at any time and does not have a specified expiration date. During the three and nine months ended September 30, 2019, the Partnership paid an aggregate of $22.5 million and $34.5 million, respectively, to repurchase and retire approximately 1.0 million units and 1.6 million units, respectively, with all of the repurchases done via open market and brokered transactions.

Quarterly Unit Exchange Program

Current and former senior Carlyle professionals are able to exchange their Carlyle Holdings partnership units for common units on a quarterly basis, subject to the terms of the Exchange Agreement. During the three and nine months ended September 30, 2019, current and former senior Carlyle professionals exchanged 1,175,224 and 1,588,977, respectively, Carlyle Holdings partnership units for common units, resulting in a reallocation of capital of $10.6 million and $13.6 million, respectively, from non-controlling interests in Carlyle Holdings to partners’ capital and accumulated other comprehensive loss.

Distributions

The table below presents information regarding the quarterly distributions on the common units, which were made at the sole discretion of the general partner of the Partnership. Because certain wholly owned subsidiaries of the Partnership must pay taxes and make payments under the tax receivable agreement, the amounts ultimately distributed to the common unitholders may be less, on a per unit basis, than the amounts distributed by the Carlyle Holdings partnerships to the other limited partners of the Carlyle Holdings partnerships in respect of their Carlyle Holdings partnership units.



Distribution Record Date	Distribution Payment Date	Distribution per Common Unit		Distribution to Common Unitholders

Total 2019 Distribution Year (through Q3 2019)		$	0.93	$	107.4

The general partner will take into account general economic and business conditions, as well as the Partnership’s strategic plans and prospects, business and investment opportunities, financial condition and obligations, legal, tax and regulatory restrictions, other constraints on the payment of distributions by the Partnership to its common unitholders or by subsidiaries to the Partnership, and other such factors as the general partner may deem relevant.

Under the Delaware Limited Partnership Act, the Partnership may not make a distribution to a partner if after the distribution all of the Partnership's liabilities, other than liabilities to partners on account of their partnership interest and

liabilities for which the recourse of creditors is limited to specific property of the partnership, would exceed the fair value of the Partnership's assets. If the Partnership were to make such an impermissible distribution, any limited partner who received a distribution and knew at the time of the distribution that the distribution was in violation of the Delaware Limited Partnership Act would be liable to the Partnership for the amount of the distribution for three years. In addition, the terms of the Partnership’s senior credit facility provide certain limits on its ability to make distributions.

Equity-Based Compensation

13. Equity-Based Compensation

In May 2012, Carlyle Group Management L.L.C., the general partner of the Partnership, adopted the Equity Incentive Plan. The Equity Incentive Plan is a source of equity-based awards permitting the Partnership to grant to Carlyle employees, directors of the Partnership’s general partner and consultants non-qualified options, unit appreciation rights, common units, restricted common units, deferred restricted common units, phantom restricted common units and other awards based on the Partnership’s common units and Carlyle Holdings partnership units. The total number of the Partnership’s common units and Carlyle Holdings partnership units which were initially available for grant under the Equity Incentive Plan was 30,450,000. The Equity Incentive Plan contains a provision which automatically increases the number of the Partnership’s common units and Carlyle Holdings partnership units available for grant based on a pre-determined formula; this increase occurs annually on January 1. As of January 1, 2019, pursuant to the formula, the total number of the Partnership’s common units and Carlyle Holdings partnership units available for grant under the Equity Incentive Plan was 33,872,427.

A summary of the status of the Partnership’s non-vested equity-based awards as of September 30, 2019 and a summary of changes for the nine months ended September 30, 2019, are presented below:



	Carlyle Holdings			The Carlyle Group L.P.
Unvested Units	Partnership Units	Weighted- Average Grant Date Fair Value		Deferred Restricted Common Units	Weighted- Average Grant Date Fair Value

Balance, September 30, 2019	9,387	$	28.26	15,080,942	$	17.12

The Partnership recorded compensation expense for deferred restricted common units of $36.5 million and $49.7 million for the three months ended September 30, 2019 and 2018, respectively, with $3.2 million and $4.7 million of corresponding deferred tax benefits, respectively. The Partnership recorded compensation expense for deferred restricted common units of $107.6 million and $143.8 million for the nine months ended September 30, 2019 and 2018, respectively, with $9.9 million and $12.9 million of corresponding deferred tax benefits, respectively. As of September 30, 2019, the total unrecognized equity-based compensation expense related to unvested deferred restricted common units is $213.5 million, which is expected to be recognized over a weighted-average term of 2.3 years.

Segment Reporting [Abstract]

Segment Reporting

14. Segment Reporting

Carlyle conducts its operations through four reportable segments:

Corporate Private Equity – The Corporate Private Equity segment is comprised of the Partnership’s operations that advise a diverse group of funds that invest in buyout, middle market and growth capital transactions that focus on either a particular geography or a particular industry.

Real Assets – The Real Assets segment is comprised of the Partnership’s operations that advise U.S. and international funds focused on real estate, infrastructure, energy and renewable energy transactions.

Global Credit – The Global Credit segment advises a group of funds that pursue investment opportunities across various types of credit, including loans & structured credit, direct lending, opportunistic credit, energy credit, distressed credit and aviation finance.

Investment Solutions – The Investment Solutions segment advises global private equity fund of funds programs and related co-investment and secondary activities through AlpInvest. This segment also includes Metropolitan, a global manager of real estate fund of funds and related co-investment and secondary activities.

The Partnership’s reportable business segments are differentiated by their various investment focuses and strategies. Overhead costs are generally allocated based on cash-based compensation and benefits expense for each segment. The Partnership’s earnings from its investment in NGP are presented in the respective operating captions within the Real Assets segment.

Distributable Earnings. Distributable Earnings, or “DE,” is a key performance benchmark used in the Partnership’s industry and is evaluated regularly by management in making resource deployment and compensation decisions and in assessing performance of the Partnership’s four reportable segments. Management also uses DE in budgeting, forecasting, and the overall management of the Partnership's segments. Management believes that reporting DE is helpful to understanding the Partnership's business and that investors should review the same supplemental financial measure that management uses to analyze the Partnership's segment performance. DE is intended to show the amount of net realized earnings without the effects of the consolidation of the Consolidated Funds. DE is derived from the Partnership's segment reported results and is used to assess performance and determine amounts potentially available for distribution from Carlyle Holdings to its unitholders.

Distributable Earnings differs from income (loss) before provision for income taxes computed in accordance with U.S. GAAP in that it includes certain tax expenses associated with performance revenues (comprised of performance allocations and incentive fees), and does not include unrealized performance allocations and related compensation expense, unrealized principal investment income, equity-based compensation expense, net income (loss) attributable to non-Carlyle interests in consolidated entities, or charges (credits) related to Carlyle corporate actions and non-recurring items. Charges (credits) related to Carlyle corporate actions and non-recurring items include: charges associated with acquisitions or strategic investments, changes in the tax receivable agreement liability, corporate conversion costs, amortization and any impairment charges associated with acquired intangible assets, transaction costs associated with acquisitions, charges associated with earnouts and contingent consideration including gains and losses associated with the estimated fair value of contingent considerations issued in conjunction with acquisitions or strategic investments, impairment charges associated with lease right-of-use assets, gains and losses from the retirement of debt, charges associated with contract terminations and employee severance. Management believes the inclusion or exclusion of these items provides investors with a meaningful indication of the Partnership’s core operating performance.

Fee Related Earnings. Fee Related Earnings, or “FRE,” is used to assess the ability of the business to cover direct base compensation and operating expenses from total fee revenues. FRE differs from income (loss) before provision for income taxes computed in accordance with U.S. GAAP in that it adjusts for the items included in the calculation of DE and also adjusts DE to exclude net realized performance revenues, realized principal investment income, net interest (interest income less interest expense), and certain general, administrative and other expenses when the timing of any future payment is uncertain.

The following table presents the financial data for the Partnership’s four reportable segments for the three and nine months ended September 30, 2019:

Summary of Significant Accounting Policies (Policies)	Sep. 30, 2019
Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation The Partnership consolidates all entities that it controls either through a majority voting interest or as the primary beneficiary of variable interest entities (“VIEs”). The Partnership evaluates (1) whether it holds a variable interest in an entity, (2) whether the entity is a VIE, and (3) whether the Partnership’s involvement would make it the primary beneficiary. In evaluating whether the Partnership holds a variable interest, fees (including management fees, incentive fees and performance allocations) that are customary and commensurate with the level of services provided, and where the Partnership does not hold other economic interests in the entity that would absorb more than an insignificant amount of the expected losses or returns of the entity, are not considered variable interests. The Partnership considers all economic interests, including indirect interests, to determine if a fee is considered a variable interest. For those entities where the Partnership holds a variable interest, the Partnership determines whether each of these entities qualifies as a VIE and, if so, whether or not the Partnership is the primary beneficiary. The assessment of whether the entity is a VIE is generally performed qualitatively, which requires judgment. These judgments include: (a) determining whether the equity investment at risk is sufficient to permit the entity to finance its activities without additional subordinated financial support, (b) evaluating whether the equity holders, as a group, can make decisions that have a significant effect on the economic performance of the entity, (c) determining whether two or more parties' equity interests should be aggregated, and (d) determining whether the equity investors have proportionate voting rights to their obligations to absorb losses or rights to receive returns from an entity. For entities that are determined to be VIEs, the Partnership consolidates those entities where it has concluded it is the primary beneficiary. The primary beneficiary is defined as the variable interest holder with (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. In evaluating whether the Partnership is the primary beneficiary, the Partnership evaluates its economic interests in the entity held either directly or indirectly by the Partnership. The Partnership’s investments in these CLOs are generally subordinated to other interests in the entities and entitle the Partnership to receive a pro rata portion of the residual cash flows, if any, from the entities. Investors in the CLOs have no recourse against the Partnership for any losses sustained in the CLO structure. Entities that do not qualify as VIEs are generally assessed for consolidation as voting interest entities. Under the voting interest entity model, the Partnership consolidates those entities it controls through a majority voting interest. All significant inter-entity transactions and balances of entities consolidated have been eliminated. Except to the extent of the consolidated assets of the VIEs, the holders of the consolidated VIEs’ liabilities generally do not have recourse to the Partnership. Substantially all of the Partnership’s Consolidated Funds are CLOs, which are VIEs that issue loans payable that are backed by diversified collateral asset portfolios consisting primarily of loans or structured debt. In exchange for managing the collateral for the CLOs, the Partnership earns investment management fees, including in some cases subordinated management fees and contingent incentive fees. In cases where the Partnership consolidates the CLOs (primarily because of a retained interest that is significant to the CLO), those management fees have been eliminated as intercompany transactions.
Investments in Unconsolidated Variable Interest Entities	Investments in Unconsolidated Variable Interest Entities The Partnership holds variable interests in certain VIEs that are not consolidated because the Partnership is not the primary beneficiary, including its investments in certain CLOs and strategic investment in NGP Management Company, L.L.C. (“NGP Management” and, together with its affiliates, “NGP”). Refer to Note 4 for information on the strategic investment in NGP. The Partnership’s involvement with such entities is in the form of direct equity interests and fee arrangements. The maximum exposure to loss represents the loss of assets recognized by the Partnership relating to its variable interests in these unconsolidated entities.
Basis of Accounting	Basis of Accounting The accompanying financial statements are prepared in accordance with U.S. GAAP. Management has determined that the Partnership’s Funds are investment companies under U.S. GAAP for the purposes of financial reporting. U.S. GAAP for an investment company requires investments to be recorded at estimated fair value and the unrealized gains and/or losses in an investment’s fair value are recognized on a current basis in the statements of operations. Additionally, the Funds do not consolidate their majority-owned and controlled investments (the “Portfolio Companies”). In the preparation of these unaudited condensed consolidated financial statements, the Partnership has retained the specialized accounting for the Funds. All of the investments held and notes issued by the Consolidated Funds are presented at their estimated fair values in the Partnership’s condensed consolidated balance sheets. Interest and other income of the Consolidated Funds as well as interest expense and other expenses of the Consolidated Funds are included in the Partnership’s unaudited condensed consolidated statements of operations.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make assumptions and estimates that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Management’s estimates are based on historical experiences and other factors, including expectations of future events that management believes to be reasonable under the circumstances. It also requires management to exercise judgment in the process of applying the Partnership’s accounting policies. Assumptions and estimates regarding the valuation of investments and their resulting impact on performance allocations involve a higher degree of judgment and complexity and these assumptions and estimates may be significant to the consolidated financial statements and the resulting impact on performance allocations and incentive fees. Actual results could differ from these estimates and such differences could be material.
Business Combinations	Business Combinations The Partnership accounts for business combinations using the acquisition method of accounting, under which the purchase price of the acquisition is allocated to the assets acquired and liabilities assumed using the fair values determined by management as of the acquisition date. Contingent consideration obligations that are elements of consideration transferred are recognized as of the acquisition date as part of the fair value transferred in exchange for the acquired business. Acquisition-related costs incurred in connection with a business combination are expensed as incurred.
Revenue Recognition and Deferred Revenue	Deferred Revenue Deferred revenue represents management fees and other revenue received prior to the balance sheet date, which has not yet been earned. The increase in the deferred revenue balance for the nine months ended September 30, 2019 was primarily driven by cash payments received in advance of the Partnership satisfying its performance obligations, partially offset by revenues that were included in the deferred revenue balance at the beginning of the period. Revenue Recognition The Partnership recognizes revenue in accordance with ASC 606, Revenue from Contracts with Customers. Revenue is recognized when the Partnership transfers promised goods or services to customers in an amount that reflects the consideration to which the Partnership expects to be entitled to in exchange for those goods or services. ASC 606 includes a five-step framework that requires an entity to: (i) identify the contract(s) with a customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations in the contract, and (v) recognize revenue when the entity satisfies a performance obligation. The Partnership accounts for performance allocations that represent a performance-based capital allocation from fund limited partners to the Partnership (commonly known as “carried interest”, which comprises substantially all of the Partnership’s previously reported performance fee revenues) as earnings from financial assets within the scope of ASC 323, Investments - Equity Method and Joint Ventures, and therefore are not in the scope of ASC 606. In accordance with ASC 323, the Partnership records equity method income (losses) as a component of investment income based on the change in its proportionate claim on net assets of the investment fund, including performance allocations, assuming the investment fund was liquidated as of each reporting date pursuant to each fund’s governing agreements. See Note 4 for additional information on the components of investments and investment income. Performance fees that do not meet the definition of performance-based capital allocations are in the scope of ASC 606 and are included in incentive fees in the consolidated statements of operations. While the determination of who is the customer in a contractual arrangement will be made on a contract-by-contract basis, the customer will generally be the investment fund for the Partnership’s significant management and advisory contracts. The customer determination impacts the Partnership’s analysis of the accounting for contract costs. Also, the recovery of certain costs incurred on behalf of Carlyle funds, primarily travel and entertainment costs, are presented gross in the unaudited condensed consolidated statements of operations, as the Partnership controls the inputs to its investment management performance obligation. Fund Management Fees The Partnership provides management services to funds in which it holds a general partner interest or has a management agreement. The Partnership considers the performance obligations in its contracts with its funds to be the promise to provide (or to arrange for third parties to provide) investment management services related to the management, policies and operations of the funds. As it relates to the Partnership’s performance obligation to provide investment management services, the Partnership typically satisfies this performance obligation over time as the services are rendered, since the funds simultaneously receive and consume the benefits provided as the Partnership performs the service. The transaction price is the amount of consideration to which the Partnership expects to be entitled in exchange for transferring the promised services to the funds. Management fees earned from each investment management contract over the contract life represent variable consideration because the consideration the Partnership is entitled to varies based on fluctuations in the basis for the management fee, for example fund net asset value (“NAV”) or AUM. Given that the management fee basis is susceptible to market factors outside of the Partnership’s influence, management fees are constrained and, therefore, estimates of future period management fees are generally not included in the transaction price. Revenue recognized for the investment management services provided is generally the amount determined at the end of the period because that is when the uncertainty for that period is resolved. For closed-end carry funds in the Corporate Private Equity, Real Assets and Global Credit segments, management fees generally range from 1.0% to 2.0% of commitments during the fund’s investment period based on limited partners’ capital commitments to the funds. Following the expiration or termination of the investment period, management fees generally are based on the lower of cost or fair value of invested capital and the rate charged may also be reduced to between 0.6% and 2.0%. For certain separately managed accounts and longer-dated carry funds, with expected terms greater than ten years, management fees generally range from 0.2% to 1.0% based on contributions for unrealized investments or the current value of the investment. The Partnership will receive management fees during a specified period of time, which is generally ten years from the initial closing date, or, in some instances, from the final closing date, but such termination date may be earlier in certain limited circumstances or later if extended for successive one-year periods, typically up to a maximum of two years. Depending upon the contracted terms of investment advisory or investment management and related agreements, these fees are generally called semi-annually in advance and are recognized as earned over the subsequent six month period. For certain longer-dated carry funds, management fees are called quarterly over the life of the funds. Within the Global Credit segment, for CLOs and other structured products, management fees generally range from 0.4% to 0.5% based on the total par amounts of assets or the aggregate principal amount of the notes in the CLO and are due quarterly based on the terms and recognized over the respective period. Management fees for the CLOs and other structured products are governed by indentures and collateral management agreements. The Partnership will receive management fees for the CLOs until redemption of the securities issued by the CLOs, which is generally five to ten years after issuance. Management fees for the business development companies are due quarterly in arrears at annual rates that range from 1.25% of invested capital to 1.5% of gross assets, excluding cash and cash equivalents. Management fees for the Partnership’s private equity and real estate carry fund vehicles in the Investment Solutions segment generally range from 0.25% to 1.0% of the vehicle’s capital commitments during the commitment fee period of the relevant fund or the weighted-average investment period of the underlying funds. Following the expiration of the commitment fee period or weighted-average investment period of such funds, the management fees generally range from 0.25% to 1.0% on (i) the lower of cost or fair value of the capital invested, (ii) the net asset value for unrealized investments, or (iii) the contributions for unrealized investments; however, certain separately managed accounts earn management fees at all times on contributions for unrealized investments or on the initial commitment amount. Management fees for the Investment Solutions carry fund vehicles are generally due quarterly and recognized over the related quarter. As of September 30, 2019 and December 31, 2018, management fee receivables were $72.8 million and $76.2 million, respectively, and are included in due from affiliates and other receivables, net, in the unaudited condensed consolidated balance sheets. Fund management fees exclude the reimbursement of any partnership expenses paid by the Partnership on behalf of the Carlyle funds pursuant to the limited partnership agreements, including amounts related to the pursuit of actual, proposed, or unconsummated investments, professional fees, expenses associated with the acquisition, holding and disposition of investments, and other fund administrative expenses. For the professional fees that the Partnership arranges for the investment funds, the Partnership concluded that the nature of its promise is to arrange for the services to be provided and it does not control the services provided by third parties before they are transferred to the customer. Therefore, the Partnership concluded it is acting in the capacity of an agent. Accordingly, the reimbursement for these professional fees paid on behalf of the investment funds is presented on a net basis in general, administrative and other expenses in the unaudited condensed consolidated statements of operations. The Partnership also incurs certain costs, primarily employee travel and entertainment costs, employee compensation and systems costs, for which it receives reimbursement from the investment funds in connection with its performance obligation to provide investment and management services. For reimbursable travel, compensation and systems costs, the Partnership concluded it controls the services provided by its employees and the resources used to develop applicable systems before they are transferred to the customer and therefore is a principal. Accordingly, the reimbursement for these costs incurred by the Partnership to manage the fund limited partnerships are presented on a gross basis in interest and other income in the unaudited condensed consolidated statements of operations and the expense in general, administrative and other expenses or cash-based compensation and benefits expenses in the unaudited condensed consolidated statements of operations. Incentive Fees In connection with management contracts from certain of its Global Credit funds, the Partnership is also entitled to receive performance-based incentive fees when the return on assets under management exceeds certain benchmark returns or other performance targets. In such arrangements, incentive fees are recognized when the performance benchmark has been achieved. Incentive fees are variable consideration because they are contingent upon the investment vehicle achieving stipulated investment return hurdles. Investment returns are highly susceptible to market factors outside of the Partnership’s influence. Accordingly, incentive fees are constrained until the uncertainty is resolved. Estimates of future period incentive fees are generally not included in the transaction price because these estimates are constrained. The transaction price for incentive fees is generally the amount determined at the end of each accounting period to which they relate because that is when the uncertainty for that period is resolved, as these fees are not subject to clawback. Investment Income (Loss), including Performance Allocations Investment income (loss) represents the unrealized and realized gains and losses resulting from the Partnership’s equity method investments, including any associated general partner performance allocations, and other principal investments, including CLOs. General partner performance allocations consist of the allocation of profits from certain of the funds to which the Partnership is entitled (commonly known as carried interest). For closed-end carry funds in the Corporate Private Equity, Real Assets and Global Credit segments, the Partnership is generally entitled to a 20% allocation (or 10% to 20% on certain longer-dated carry funds, certain credit funds, up to 25% on certain Corporate Private Equity funds in the event performance benchmarks are achieved, and external co-investment vehicles, or approximately 2% to 10% for most of the Investment Solutions segment carry fund vehicles) of the net realized income or gain as a carried interest after returning the invested capital, the allocation of preferred returns of generally 7% to 9% (or 4% to 7% for certain longer-dated carry funds) and return of certain fund costs (generally subject to catch-up provisions as set forth in the fund limited partnership agreement). Carried interest is recognized upon appreciation of the funds’ investment values above certain return hurdles set forth in each respective partnership agreement. The Partnership recognizes revenues attributable to performance allocations based upon the amount that would be due pursuant to the fund partnership agreement at each period end as if the funds were terminated at that date. Accordingly, the amount recognized as investment income for performance allocations reflects the Partnership’s share of the gains and losses of the associated funds’ underlying investments measured at their then-current fair values relative to the fair values as of the end of the prior period. Because of the inherent uncertainty, these estimated values may differ significantly from the values that would have been used had a ready market for the investments existed, and it is reasonably possible that the difference could be material. Carried interest is ultimately realized when: (i) an underlying investment is profitably disposed of, (ii) certain costs borne by the limited partner investors have been reimbursed, (iii) the fund’s cumulative returns are in excess of the preferred return and (iv) the Partnership has decided to collect carry rather than return additional capital to limited partner investors. Realized carried interest may be required to be returned by the Partnership in future periods if the funds’ investment values decline below certain levels. When the fair value of a fund’s investments remains constant or falls below certain return hurdles, previously recognized performance allocations are reversed. In all cases, each fund is considered separately in this regard, and for a given fund, performance allocations can never be negative over the life of a fund. If upon a hypothetical liquidation of a fund’s investments at their then-current fair values, previously recognized and distributed carried interest would be required to be returned, a liability is established for the potential giveback obligation. Principal investment income (loss) is realized when the Partnership redeems all or a portion of its investment or when the Partnership receives or is due cash income, such as dividends or distributions. Principal investment income (loss) also includes the Partnership’s allocation of earnings from its investment in Fortitude Re. As it relates to the Partnership’s investments in NGP (see Note 4), principal investment income includes the related amortization of the basis difference between the Partnership’s carrying value of its investment and the Partnership’s share of underlying net assets of the investee, as well as the compensation expense associated with compensatory arrangements provided by the Partnership to employees of its equity method investee. Unrealized principal investment income (loss) results from the Partnership's proportionate share of the investee's unrealized earnings, including changes in the fair value of the underlying investment, as well as the reversal of unrealized gain (loss) at the time an investment is realized. Interest Income Interest income is recognized when earned. For debt securities representing non-investment grade beneficial interests in securitizations, the effective yield is determined based on the estimated cash flows of the security. Changes in the effective yield of these securities due to changes in estimated cash flows are recognized on a prospective basis as adjustments to interest income in future periods. Interest income earned by the Partnership is included in interest and other income in the accompanying unaudited condensed consolidated statements of operations. Interest income of the Consolidated Funds was $49.8 million and $57.9 million for the three months ended September 30, 2019 and 2018, respectively, $144.5 million and $155.9 million for the nine months ended September 30, 2019 and 2018, respectively, and is included in interest and other income of Consolidated Funds in the accompanying unaudited condensed consolidated statements of operations. The Partnership also provides transaction advisory and portfolio advisory services to the portfolio companies, and where covered by separate contractual agreements, recognizes fees for these services when the performance obligation has been satisfied and collection is reasonably assured.
Compensation and Benefits	Compensation and Benefits Cash-based Compensation and Benefits – Cash-based compensation and benefits includes salaries, bonuses (discretionary awards and guaranteed amounts), performance payment arrangements and benefits paid and payable to Carlyle employees. Bonuses are accrued over the service period to which they relate. Equity-Based Compensation – Compensation expense relating to the issuance of equity-based awards to Carlyle employees is measured at fair value on the grant date. In June 2018, the Partnership adopted ASU 2018-7, Improvements to Nonemployee Share-Based Payment Accounting, which aligned the accounting for non-employee equity-based awards with the accounting for employee equity-based awards, retroactive to January 1, 2018. The compensation expense for awards that vest over a future service period is recognized over the relevant service period on a straight-line basis. The compensation expense for awards that do not require future service is recognized immediately. Cash settled equity-based awards are classified as liabilities and are re-measured at the end of each reporting period. The compensation expense for awards that contain performance conditions is recognized when it is probable that the performance conditions will be achieved; in certain instances, such compensation expense may be recognized prior to the grant date of the award. The compensation expense for awards that contain market conditions is based on a grant-date fair value that factors in the probability that the market conditions will be achieved and is recognized over the requisite service period on a straight-line basis. Equity-based awards issued to non-employees are generally recognized as general, administrative and other expenses, except to the extent they are recognized as part of the Partnership’s equity method earnings because they are issued to employees of equity method investees. The Partnership recognizes equity-based award forfeitures in the period they occur as a reversal of previously recognized compensation expense. The reduction in compensation expense is determined based on the specific awards forfeited during that period. Furthermore, the Partnership recognizes all excess tax benefits and deficiencies as income tax benefit or expense in the unaudited condensed consolidated statement of operations. Performance Allocations and Incentive Fee Related Compensation – A portion of the performance allocations and incentive fees earned is due to employees and advisors of the Partnership. These amounts are accounted for as compensation expense in conjunction with the recognition of the related performance allocations and incentive fee revenue and, until paid, are recognized as a component of the accrued compensation and benefits liability. Accordingly, upon a reversal of performance allocations or incentive fee revenue, the related compensation expense, if any, is also reversed.
Income Taxes	Income Taxes Certain of the wholly-owned subsidiaries of the Partnership and the Carlyle Holdings partnerships are subject to federal, state, local and foreign corporate income taxes at the entity level and the related tax provision attributable to the Partnership’s share of this income is reflected in the unaudited condensed consolidated financial statements. Based on applicable federal, foreign, state and local tax laws, the Partnership records a provision for income taxes for certain entities. Tax positions taken by the Partnership are subject to periodic audit by U.S. federal, state, local and foreign taxing authorities. On July 31, 2019, the Partnership announced its decision to convert the Carlyle Group L.P. from a Delaware limited partnership to a Delaware corporation named The Carlyle Group Inc. The Partnership accounts for income taxes using the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future consequences of events that have been included in the financial statements or tax returns. Under this method, deferred tax assets and liabilities are determined based on the difference between the financial statement reporting and the tax basis of assets and liabilities using enacted tax rates in effect for the period in which the difference is expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in the period of the change in the provision for income taxes. Further, deferred tax assets are recognized for the expected realization of available net operating loss and tax credit carry forwards. A valuation allowance is recorded on the Partnership’s gross deferred tax assets when it is “more likely than not” that such asset will not be realized. When evaluating the realizability of the Partnership’s deferred tax assets, all evidence, both positive and negative, is evaluated. Items considered in this analysis include the ability to carry back losses, the reversal of temporary differences, tax planning strategies, and expectations of future earnings. Under U.S. GAAP for income taxes, the amount of tax benefit to be recognized is the amount of benefit that is “more likely than not” to be sustained upon examination. The Partnership analyzes its tax filing positions in all of the U.S. federal, state, local and foreign tax jurisdictions where it is required to file income tax returns, as well as for all open tax years in these jurisdictions. If, based on this analysis, the Partnership determines that uncertainties in tax positions exist, a liability is established, which is included in accounts payable, accrued expenses and other liabilities in the unaudited condensed consolidated financial statements. The Partnership recognizes accrued interest and penalties related to unrecognized tax positions in the provision for income taxes. If recognized, the entire amount of unrecognized tax positions would be recorded as a reduction in the provision for income taxes.
Tax Receivable Agreement	Tax Receivable Agreement Exchanges of Carlyle Holdings partnership units for the Partnership’s common units that are executed by the limited partners of the Carlyle Holdings partnerships result in transfers of and increases in the tax basis of the tangible and intangible assets of Carlyle Holdings, primarily attributable to a portion of the goodwill inherent in the business. These transfers and increases in tax basis will increase (for tax purposes) depreciation and amortization and therefore reduce the amount of tax that certain of the Partnership’s subsidiaries, including Carlyle Holdings I GP Inc., which are referred to as the “corporate taxpayers,” would otherwise be required to pay in the future. This increase in tax basis may also decrease gain (or increase loss) on future dispositions of certain capital assets to the extent tax basis is allocated to those capital assets. The Partnership has entered into a tax receivable agreement with the limited partners of the Carlyle Holdings partnerships whereby the corporate taxpayers have agreed to pay to the limited partners of the Carlyle Holdings partnerships involved in any exchange transaction 85% of the amount of cash tax savings, if any, in U.S. federal, state and local income tax or foreign or franchise tax that the corporate taxpayers realize as a result of these increases in tax basis and, in limited cases, transfers or prior increases in tax basis. The corporate taxpayers expect to benefit from the remaining 15% of cash tax savings, if any, in income tax they realize. Payments under the tax receivable agreement will be based on the tax reporting positions that the Partnership will determine. The corporate taxpayers will not be reimbursed for any payments previously made under the tax receivable agreement if a tax basis increase is successfully challenged by the Internal Revenue Service. The Partnership records an increase in deferred tax assets for the estimated income tax effects of the increases in tax basis based on enacted federal and state tax rates at the date of the exchange. To the extent that the Partnership estimates that the corporate taxpayers will not realize the full benefit represented by the deferred tax asset, based on an analysis that will consider, among other things, its expectation of future earnings, the Partnership will reduce the deferred tax asset with a valuation allowance and will assess the probability that the related liability owed under the tax receivable agreement will be paid. The Partnership records 85% of the estimated realizable tax benefit (which is the recorded deferred tax asset less any recorded valuation allowance) as an increase to the liability due under the tax receivable agreement, which is included in due to affiliates in the accompanying condensed consolidated financial statements. The remaining 15% of the estimated realizable tax benefit is initially recorded as an increase to the Partnership’s partners’ capital. All of the effects to the deferred tax asset of changes in any of the Partnership’s estimates after the tax year of the exchange will be reflected in the provision for income taxes. Similarly, the effect of subsequent changes in the enacted tax rates will be reflected in the provision for income taxes.
Non-controlling Interests	Non-controlling Interests Non-controlling interests in consolidated entities represent the component of equity in consolidated entities held by third-party investors. These interests are adjusted for general partner allocations which occur during the reporting period. Any change in ownership of a subsidiary while the controlling financial interest is retained is accounted for as an equity transaction between the controlling and non-controlling interests. Transaction costs incurred in connection with such changes in ownership of a subsidiary are recorded as a direct charge to partners’ capital. Non-controlling interests in Carlyle Holdings relate to the ownership interests of the other limited partners of the Carlyle Holdings partnerships. The Partnership, through wholly-owned subsidiaries, is the sole general partner of Carlyle Holdings. Accordingly, the Partnership consolidates Carlyle Holdings into its consolidated financial statements, and the other ownership interests in Carlyle Holdings are reflected as non-controlling interests in the Partnership’s unaudited condensed consolidated financial statements. Any change to the Partnership’s ownership interest in Carlyle Holdings while it retains the controlling financial interest in Carlyle Holdings is accounted for as a transaction within partners’ capital as a reallocation of ownership interests in Carlyle Holdings.
Earnings Per Common Unit	Earnings Per Common Unit The Partnership computes earnings per common unit in accordance with ASC 260, Earnings Per Share. Basic earnings per common unit is calculated by dividing net income (loss) attributable to the common units of the Partnership by the weighted-average number of common units outstanding for the period. Diluted earnings per common unit reflects the assumed conversion of all dilutive securities. Net income (loss) attributable to the common units excludes net income (loss) and dividends attributable to any participating securities under the two-class method of ASC 260.
Investments and Corporate Treasury Investments	Investments Investments include (i) the Partnership’s ownership interests (typically general partner interests) in the Funds, (ii) strategic investments made by the Partnership (both of which are accounted for as equity method investments), (iii) the investments held by the Consolidated Funds (which are presented at fair value in the Partnership’s unaudited condensed consolidated financial statements), and (iv) certain credit-oriented investments, including investments in the CLOs (which are accounted for as trading securities). The valuation procedures utilized for investments of the Funds vary depending on the nature of the investment. The fair value of investments in publicly-traded securities is based on the closing price of the security with adjustments to reflect appropriate discounts if the securities are subject to restrictions. The fair value of non-equity securities or other investments, which may include instruments that are not listed on an exchange, considers, among other factors, external pricing sources, such as dealer quotes or independent pricing services, recent trading activity or other information that, in the opinion of the Partnership, may not have been reflected in pricing obtained from external sources. When valuing private securities or assets without readily determinable market prices, the Partnership gives consideration to operating results, financial condition, economic and/or market events, recent sales prices and other pertinent information. These valuation procedures may vary by investment, but include such techniques as comparable public market valuation, comparable acquisition valuation and discounted cash flow analysis. Because of the inherent uncertainty, these estimated values may differ significantly from the values that would have been used had a ready market for the investments existed, and it is reasonably possible that the difference could be material. Furthermore, there is no assurance that, upon liquidation, the Partnership will realize the values presented herein. Upon the sale of a security or other investment, the realized net gain or loss is computed on a weighted average cost basis, with the exception of the investments held by the CLOs, which compute the realized net gain or loss on a first in, first out basis. Securities transactions are recorded on a trade date basis. Corporate Treasury Investments Corporate treasury investments represent investments in U.S. Treasury and government agency obligations, commercial paper, certificates of deposit, other investment grade securities and other investments with original maturities of greater than three months when purchased. These investments are accounted for as trading securities in which changes in the fair value of each investment are recorded through investment income (loss). Any interest earned on debt investments is recorded through interest and other income.
Principal Equity Method Investments	Principal Equity Method Investments The Partnership accounts for all investments in which it has or is otherwise presumed to have significant influence, including investments in the unconsolidated Funds and strategic investments, using the equity method of accounting. The carrying value of equity method investments is determined based on amounts invested by the Partnership, adjusted for the equity in earnings or losses of the investee (including performance allocations) allocated based on the respective partnership agreement, less distributions received. The Partnership evaluates its equity method investments for impairment whenever events or changes in circumstances indicate that the carrying amounts of such investments may not be recoverable.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents include cash held at banks and cash held for distributions, including investments with original maturities of less than three months when purchased.
Cash and Cash Equivalents Held at Consolidated Funds	Cash and Cash Equivalents Held at Consolidated Funds Cash and cash equivalents held at Consolidated Funds consists of cash and cash equivalents held by the Consolidated Funds, which, although not legally restricted, is not available to fund the general liquidity needs of the Partnership.
Restricted Cash	Restricted Cash Restricted cash primarily represents cash held by the Partnership’s foreign subsidiaries due to certain government regulatory capital requirements as well as certain amounts held on behalf of Carlyle funds.
Derivative Instruments	Derivative Instruments The Partnership uses derivative instruments primarily to reduce its exposure to changes in foreign currency exchange rates. Derivative instruments are recognized at fair value in the unaudited condensed consolidated balance sheets with changes in fair value recognized in the unaudited condensed consolidated statements of operations for all derivatives not designated as hedging instruments.
Securities Sold Under Agreements to Repurchase	Securities Sold Under Agreements to Repurchase As it relates to certain European CLOs sponsored by the Partnership, securities sold under agreements to repurchase (“repurchase agreements”) are accounted for as collateralized financing transactions. The Partnership provides securities to counterparties to collateralize amounts borrowed under repurchase agreements on terms that permit the counterparties to repledge or resell the securities to others. As of September 30, 2019, $40.6 million of securities were transferred to counterparties under repurchase agreements and are included within investments in the condensed consolidated balance sheets. Cash received under repurchase agreements is recognized as a liability within debt obligations in the condensed consolidated balance sheets. Interest expense is recognized on an effective yield basis and is included within interest expense in the condensed consolidated statements of operations.
Fixed Assets	Fixed Assets Fixed assets consist of furniture, fixtures and equipment, leasehold improvements, and computer hardware and software and are stated at cost, less accumulated depreciation and amortization. Depreciation is recognized on a straight-line method over the assets’ estimated useful lives, which for leasehold improvements are the lesser of the lease terms or the life of the asset, and three to seven years for other fixed assets. Fixed assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable.
Leases	Leases On January 1, 2019, the Partnership adopted ASU 2016-2, Leases (Topic 842) under the modified retrospective method. ASU 2016-2, and related amendments, requires lessees to recognize virtually all of their leases on the balance sheet by recording right-of-use assets and lease liabilities. The lease liability is measured at the present value of lease payments and the right-of-use asset is based on the lease liability value, subject to adjustments for deferred rent, lease incentives, unamortized initial direct costs, or impairment. As of December 31, 2018, there was $65.2 million of deferred rent and lease incentives that was reclassified from accounts payable, accrued expenses and other liabilities into right-of-use assets upon the adoption of ASU 2016-2. Leases can be classified as either operating leases or finance leases. Operating leases will result in straight-line lease expense, while finance leases will result in front-loaded expense. The adoption of this guidance did not have a material impact on operating results. The Partnership elected the transition option provided by the FASB, which allows entities to not apply ASC 842 in the comparative periods presented in the financial statements in the year of adoption. The Partnership also elected to use the practical expedients available under the transition provisions under which the Partnership did not need to reassess whether an arrangement is or contains a lease, lease classification, and the accounting for initial direct costs. The Partnership recognizes a lease liability and right-of-use asset in the condensed consolidated balance sheet for contracts that it determines are leases or contain a lease. The Partnership’s leases primarily consist of operating leases for office space in various countries around the world. The Partnership also has operating leases for office equipment and vehicles, which are not significant. The Partnership does not separate non-lease components from lease components for its office space and equipment operating leases and instead accounts for each separate lease component and its associated non-lease component as a single lease component. Right-of-use assets represent the Partnership’s right to use an underlying asset for the lease term and lease liabilities represent the Partnership’s obligation to make lease payments arising from the leases. The Partnership’s right-of-use assets and lease liabilities are recognized at lease commencement based on the present value of lease payments over the lease term. Lease right-of-use assets include initial direct costs incurred by the Partnership and are presented net of deferred rent and lease incentives. Absent an implicit interest rate in the lease, the Partnership uses its incremental borrowing rate, adjusted for the effects of collateralization, based on the information available at commencement in determining the present value of lease payments. The Partnership’s lease terms may include options to extend or terminate the lease when it is reasonably certain that the Partnership will exercise those options. Lease expense for lease payments is recognized on a straight-line basis over the lease term. The Partnership does not recognize a lease liability or right-of-use asset on the balance sheet for short-term leases. Instead, the Partnership recognizes short-term lease payments as an expense on a straight-line basis over the lease term. A short-term lease is defined as a lease that, at the commencement date, has a lease term of 12 months or less and does not include an option to purchase the underlying asset that the lessee is reasonably certain to exercise. When determining whether a lease qualifies as a short-term lease, the Partnership evaluates the lease term and the purchase option in the same manner as all other leases.
Intangible Assets and Goodwill	Goodwill represents the excess of cost over the identifiable net assets of businesses acquired and is recorded in the functional currency of the acquired entity. Goodwill is recognized as an asset and is reviewed for impairment annually as of October 1st and between annual tests when events and circumstances indicate that impairment may have occurred. Intangible Assets and Goodwill The Partnership’s intangible assets consist of acquired contractual rights to earn future fee income, including management and advisory fees, customer relationships, and acquired trademarks. Finite-lived intangible assets are amortized over their estimated useful lives, which range from four to ten years, and are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable.
Accumulated Other Comprehensive Income (Loss)	Accumulated Other Comprehensive Income (Loss) The Partnership’s accumulated other comprehensive income (loss) is comprised of foreign currency translation adjustments and gains and losses on defined benefit plans sponsored by AlpInvest.
Foreign Currency Translation	Foreign Currency Translation Non-U.S. dollar denominated assets and liabilities are translated at period-end rates of exchange, and the unaudited condensed consolidated statements of operations are translated at rates of exchange in effect throughout the period.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In August 2018, the SEC adopted amendments to certain disclosure requirements in Securities Act Release No. 33-10532, Disclosure Update and Simplification. The amendments became effective on November 5, 2018. Among the amendments is the requirement to present the changes in shareholders’ equity in the interim financial statements (either in a separate statement or footnote) in quarterly reports on Form 10-Q. The Partnership included a separate statement of changes in partners’ capital in these condensed consolidated financial statements. Recently Issued Accounting Standards Adopted as of January 1, 2019 In February 2018, the FASB issued ASU 2018-2, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. ASU 2018-2 allows a reclassification from accumulated other comprehensive income to partners’ capital for stranded effects resulting from the Tax Cuts and Jobs Act. The guidance was effective for the Partnership on January 1, 2019 and the Partnership adopted this guidance on that date. The impact of this guidance was not material to the Partnership. In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815) - Targeted Improvements to Accounting for Hedging Activities. ASU 2017-12, among other things, permits hedge accounting for risk components in hedging relationships to now involve nonfinancial risk components and requires an entity to present the earnings effect of the hedging instrument in the same income statement line item in which the earnings effect of the hedge item is reported. The guidance was effective for the Partnership on January 1, 2019 and requires cash flow hedges and net investment hedges existing at the date of adoption to apply a cumulative effect adjustment to eliminate the measurement of ineffectiveness to accumulated other comprehensive income with a corresponding adjustment to the opening balance of partners’ capital as of the beginning of the fiscal year that an entity adopts the guidance. The amended presentation and disclosure guidance is required only prospectively. The Partnership adopted this guidance on January 1, 2019 and the impact was not material. Recently Issued Accounting Standards Effective on January 1, 2020 In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820) - Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement. ASU 2018-13 eliminates, adds and modifies certain disclosure requirements for fair value measurements. This guidance is effective for the Partnership on January 1, 2020 and early adoption is permitted. The Partnership is currently assessing the potential impact of this guidance to the fair value disclosures. In January 2017, the FASB issued ASU 2017-4, Intangibles - Goodwill and Other (Topic 350) - Simplifying the Test for Goodwill Impairment. ASU 2017-04 simplifies an entity’s annual goodwill test for impairment by eliminating the requirement to calculate the implied fair value of goodwill, and instead an entity should compare the fair value of a reporting unit with its carrying amount. The impairment charge will then be the amount by which the carrying amount exceeds the reporting unit’s fair value. An entity would still have the option to perform a qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. The guidance is effective for the Partnership on January 1, 2020 and requires the guidance to be applied using a prospective transition method. Early adoption is permitted. The Partnership does not expect the impact of this guidance to be material. In June 2016, the FASB issued ASU 2016-13, Accounting for Financial Instruments - Credit Losses (Topic 326). ASU 2016-13 requires an organization to measure all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Currently, GAAP requires an “incurred loss” methodology that delays recognition until it is probable a loss has been incurred. Under the new standard, the allowance for credit losses must be deducted from the amortized cost of the financial asset to present the net amount expected to be collected. The income statement will reflect the measurement of credit losses for newly recognized financial assets as well as the expected increases or decreases of expected credit losses that have taken place during the period. This provision of the guidance requires a modified retrospective transition method and will result in a cumulative-effect adjustment in retained earnings upon adoption. This guidance is effective for the Partnership on January 1, 2020 and early adoption is permitted. The Partnership has identified all of the material financial assets that are within the scope of this guidance and does not expect the impact of this guidance to be material.
Fair Value Measurement	The fair value measurement accounting guidance establishes a hierarchical disclosure framework which ranks the observability of market price inputs used in measuring financial instruments at fair value. The observability of inputs is impacted by a number of factors, including the type of financial instrument, the characteristics specific to the financial instrument and the state of the marketplace, including the existence and transparency of transactions between market participants. Financial instruments with readily available quoted prices, or for which fair value can be measured from quoted prices in active markets, will generally have a higher degree of market price observability and a lesser degree of judgment applied in determining fair value. Financial instruments measured and reported at fair value are classified and disclosed based on the observability of inputs used in the determination of fair values, as follows: Level I – inputs to the valuation methodology are quoted prices available in active markets for identical instruments as of the reporting date. The types of financial instruments in this category include unrestricted securities, such as equities and derivatives, listed in active markets. The Partnership does not adjust the quoted price for these instruments, even in situations where the Partnership holds a large position and a sale could reasonably impact the quoted price. Level II – inputs to the valuation methodology are other than quoted prices in active markets, which are either directly or indirectly observable as of the reporting date. The types of financial instruments in this category include less liquid and restricted securities listed in active markets, securities traded in other than active markets, government and agency securities, and certain over-the-counter derivatives where the fair value is based on observable inputs. Level III – inputs to the valuation methodology are unobservable and significant to overall fair value measurement. The inputs into the determination of fair value require significant management judgment or estimation. The types of financial instruments in this category include investments in privately-held entities, non-investment grade residual interests in securitizations, collateralized loan obligations, and certain over-the-counter derivatives where fair value is based on unobservable inputs. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, the determination of which category within the fair value hierarchy is appropriate for any given financial instrument is based on the lowest level of input that is significant to the fair value measurement. The Partnership’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the financial instrument. In certain cases, debt and equity securities are valued on the basis of prices from an orderly transaction between market participants provided by reputable dealers or pricing services. In determining the value of a particular investment, pricing services may use certain information with respect to transactions in such investments, quotations from dealers, pricing matrices, market transactions in comparable investments and various relationships between investments.

Income Tax Disclosure [Abstract]
Income Taxes	9. Income Taxes The Partnership is generally organized as a series of pass through entities pursuant to the United States Internal Revenue Code. As such, the Partnership is not responsible for the tax liability due on certain income earned during the year. Such income is taxed at the unitholder and non-controlling interest holder level, and any income tax is the responsibility of the unitholders and is paid at that level. For income taxes on income earned for which the Partnership is responsible for the tax liability, the Partnership’s income tax expense was $9.4 million and $17.4 million for the three months ended September 30, 2019 and 2018, respectively, and $48.9 million and $36.8 million for the nine months ended September 30, 2019 and 2018, respectively. In the normal course of business, the Partnership is subject to examination by federal and certain state, local and foreign tax regulators. With a few exceptions, as of September 30, 2019, the Partnership’s U.S. federal income tax returns for the years 2016 through 2018 are open under the normal three-year statute of limitations and therefore subject to examination. State and local tax returns are generally subject to audit from 2014 to 2018. Foreign tax returns are generally subject to audit from 2011 to 2018. Certain of the Partnership’s affiliates are currently under audit by federal, state and foreign tax authorities. The Partnership does not believe that the outcome of these audits will require it to record material reserves for uncertain tax positions or that the outcome will have a material impact on the consolidated financial statements. The Partnership does not believe that it has any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly increase or decrease within the next twelve months.
