Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies The significant accounting policies of the Company are described below. The accounting policies of the Company's unconsolidated ventures are substantially similar to those of the Company. Basis of Presentation The accompanying unaudited interim financial statements have been prepared in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all information and footnotes required by accounting principles generally accepted in the United States of America (“GAAP”) for complete financial statements. These statements reflect all normal and recurring adjustments which, in the opinion of management, are necessary to present fairly the financial position, results of operations and cash flows of the Company for the interim periods presented. However, the results of operations for the interim period presented are not necessarily indicative of the results that may be expected for the year ending December 31, 2020, or any other future period. These interim financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in, or presented as exhibits to, the Company’s Annual Report on Form 10-K for the year ended December 31, 2019. The accompanying consolidated financial statements include the accounts of the Company and its controlled subsidiaries. All significant intercompany accounts and transactions have been eliminated. The portions of equity, net income and other comprehensive income of consolidated subsidiaries that are not attributable to the parent are presented separately as amounts attributable to noncontrolling interests in the consolidated financial statements. A substantial portion of noncontrolling interests represents interests held by private investment funds or other investment vehicles managed by the Company and which invest alongside the Company and membership interests in OP primarily held by certain employees of the Company. To the extent the Company consolidates a subsidiary that is subject to industry-specific guidance, the Company retains the industry-specific guidance applied by that subsidiary in its consolidated financial statements. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates and assumptions. Principles of Consolidation The Company consolidates entities in which it has a controlling financial interest by first considering if an entity meets the definition of a variable interest entity ("VIE") for which the Company is deemed to be the primary beneficiary, or if the Company has the power to control an entity through a majority of voting interest or through other arrangements. Variable Interest Entities—A VIE is an entity that either (i) lacks sufficient equity to finance its activities without additional subordinated financial support from other parties; (ii) whose equity holders lack the characteristics of a controlling financial interest; or (iii) is established with non-substantive voting rights. A VIE is consolidated by its primary beneficiary, which is defined as the party who has a controlling financial interest in the VIE through (a) power to direct the activities of the VIE that most significantly affect the VIE’s economic performance, and (b) obligation to absorb losses or right to receive benefits of the VIE that could be significant to the VIE. The Company also considers interests held by its related parties, including de facto agents. The Company assesses whether it is a member of a related party group that collectively meets the power and benefits criteria and, if so, whether the Company is most closely associated with the VIE. In performing the related party analysis, the Company considers both qualitative and quantitative factors, including, but not limited to: the amount and characteristics of its investment relative to the related party; the Company’s and the related party's ability to control or significantly influence key decisions of the VIE including consideration of involvement by de facto agents; the obligation or likelihood for the Company or the related party to fund operating losses of the VIE; and the similarity and significance of the VIE’s business activities to those of the Company and the related party. The determination of whether an entity is a VIE, and whether the Company is the primary beneficiary, may involve significant judgment, including the determination of which activities most significantly affect the entities’ performance, and estimates about the current and future fair values and performance of assets held by the VIE. Voting Interest Entities—Unlike VIEs, voting interest entities have sufficient equity to finance their activities and equity investors exhibit the characteristics of a controlling financial interest through their voting rights. The Company consolidates such entities when it has the power to control these entities through ownership of a majority of the entities' voting interests or through other arrangements. At each reporting period, the Company reassesses whether changes in facts and circumstances cause a change in the status of an entity as a VIE or voting interest entity, and/or a change in the Company's consolidation assessment. Changes in consolidation status are applied prospectively. An entity may be consolidated as a result of this reassessment, in which case, the assets, liabilities and noncontrolling interest in the entity are recorded at fair value upon initial consolidation. Any existing equity interest held by the Company in the entity prior to the Company obtaining control will be remeasured at fair value, which may result in a gain or loss recognized upon initial consolidation. However, if the consolidation represents an asset acquisition of a voting interest entity, the Company's existing interest in the acquired assets, if any, is not remeasured to fair value but continues to be carried at historical cost. The Company may also deconsolidate a subsidiary as a result of this reassessment, which may result in a gain or loss recognized upon deconsolidation depending on the carrying values of deconsolidated assets and liabilities compared to the fair value of any interests retained. Noncontrolling Interests Redeemable Noncontrolling Interests—This represents noncontrolling interests in the Company's digital investment management business and in consolidated open-end funds sponsored by the Company. The noncontrolling interests either have redemption rights that will be triggered upon the occurrence of certain events (Note 16) or have the ability to withdraw all or a portion of their interests from the consolidated open-end funds in cash with advance notice. Redeemable noncontrolling interests is presented outside of permanent equity. Allocation of net income or loss to redeemable noncontrolling interests is based upon their ownership percentage during the period. The carrying amount of redeemable noncontrolling interests is adjusted to its redemption value at the end of each reporting period to an amount not less than its initial carrying value, except for amounts contingently redeemable which will be adjusted to redemption value only when redemption is probable. Such adjustments will be recognized in additional paid-in capital. Noncontrolling Interests in Investment Entities—This represents predominantly interests in consolidated investment entities held by private investment funds or retail companies managed by the Company or held by third party joint venture partners. Allocation of net income or loss is generally based upon relative ownership interests held by equity owners in each investment entity, or based upon contractual arrangements that may provide for disproportionate allocation of economic returns among equity interests, including using a hypothetical liquidation at book value basis, where applicable and substantive. Noncontrolling Interests in Operating Company—This represents membership interests in OP held primarily by certain employees of the Company. Noncontrolling interests in OP are allocated a share of net income or loss in OP based on their weighted average ownership interest in OP during the period. Noncontrolling interests in OP have the right to require OP to redeem part or all of such member’s membership units in OP ("OP Units") for cash based on the market value of an equivalent number of shares of class A common stock at the time of redemption, or at the Company's election as managing member of OP, through issuance of shares of class A common stock (registered or unregistered) on a one-for-one basis. At the end of each reporting period, noncontrolling interests in OP is adjusted to reflect their ownership percentage in OP at the end of the period, through a reallocation between controlling and noncontrolling interests in OP, as applicable. Business Combinations Definition of a Business—The Company evaluates each purchase transaction to determine whether the acquired assets meet the definition of a business. If substantially all of the fair value of gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets, then the set of transferred assets and activities is not a business. If not, for an acquisition to be considered a business, it would have to include an input and a substantive process that together significantly contribute to the ability to create outputs (i.e., there is a continuation of revenue before and after the transaction). A substantive process is not ancillary or minor, cannot be replaced without significant costs, effort or delay or is otherwise considered unique or scarce. To qualify as a business without outputs, the acquired assets would require an organized workforce with the necessary skills, knowledge and experience that performs a substantive process. Asset Acquisitions—For acquisitions that are not deemed to be businesses, the assets acquired are recognized based on their cost to the Company as the acquirer and no gain or loss is recognized. The cost of assets acquired in a group is allocated to individual assets within the group based on their relative fair values and does not give rise to goodwill. Transaction costs related to acquisition of assets are included in the cost basis of the assets acquired. Business Combinations—The Company accounts for acquisitions that qualify as business combinations by applying the acquisition method. Transaction costs related to acquisition of a business are expensed as incurred and excluded from the fair value of consideration transferred. The identifiable assets acquired, liabilities assumed and noncontrolling interests in an acquired entity are recognized and measured at their estimated fair values. The excess of the fair value of consideration transferred over the fair values of identifiable assets acquired, liabilities assumed and noncontrolling interests in an acquired entity, net of fair value of any previously held interest in the acquired entity, is recorded as goodwill. Such valuations require management to make significant estimates and assumptions. Contingent Consideration—Contingent consideration is classified as a liability or equity, as applicable. Contingent consideration in connection with the acquisition of a business is measured at fair value on acquisition date, and unless classified as equity, is remeasured at fair value each reporting period thereafter until the consideration is settled, with changes in fair value included in net income. Contingent consideration in connection with the acquisition of assets is generally recognized only when the contingency is resolved, as part of the basis of the acquired assets. Discontinued Operations If the disposition of a component, being an operating or reportable segment, business unit, subsidiary or asset group, represents a strategic shift that has or will have a major effect on the Company’s operations and financial results, the operating profits or losses of the component when classified as held for sale, and the gain or loss upon disposition of the component, are presented as discontinued operations in the statements of operations. A business or asset group acquired in connection with a purchase business combination that meets the criteria to be accounted for as held for sale at the date of acquisition is reported as discontinued operations, regardless of whether it meets the strategic shift criteria. The pending disposition of the hotel business, composed of the Hospitality segment and the THL Hotel Portfolio in the Other segment, and the disposition of the industrial business in December 2019, including its related management platform, represent strategic shifts that have major effects on the Company’s operations and financial results, and have met the criteria as held for sale and discontinued operations in September 2020 and June 2019, respectively. Accordingly, for all prior periods presented, the related assets and liabilities are presented as assets and liabilities held for disposition on the consolidated balance sheets (Note 8) and the related operating results are presented as income from discontinued operations on the consolidated statements of operations (Note 16). Reclassifications Reclassifications were made related to discontinued operations as discussed above and to prior period segment reporting presentation as discussed in Note 22. Additionally, interest receivable, which was included in other assets as of December 31, 2019, has been reclassified to be presented as part of loans receivable to conform to current period presentation. These reclassification did not affect the Company's financial position, results of operations or cash flows. Accounting Standards Adopted in 2020 Credit Losses In June 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2016-13, Financial Instruments—Credit Losses, followed by subsequent amendments, which modifies the credit impairment model for financial instruments, and codified as Accounting Standards Codification ("ASC") Topic 326. The multiple existing incurred loss models are replaced with a lifetime current expected credit loss ("CECL") model for off-balance sheet credit exposures that are not unconditionally cancellable by the lender and financial instruments carried at amortized cost, such as loans, loan commitments, held-to-maturity ("HTM") debt securities, financial guarantees, net investment in sales-type and direct financing leases, reinsurance and trade receivables. Targeted changes are also made to the impairment model of available-for-sale ("AFS") debt securities which are not within the scope of CECL. The CECL model, in estimating expected credit losses over the life of a financial instrument at the time of origination or acquisition, considers historical loss experience, current conditions and the effects of a reasonable and supportable expectation of changes in future macroeconomic conditions. Recognition of allowance for credit losses under the CECL model will generally be accelerated as it encompasses credit losses over the full remaining expected life of the affected financial instruments. For collateralized financial assets, measurement of credit losses under CECL is based on fair value of the collateral if foreclosure is probable or if the collateral-dependent practical expedient is elected for financial assets expected to be repaid substantially through operation or sale of the collateral when the borrower is experiencing financial difficulty. The accounting model for purchased credit-impaired loans and debt securities will be simplified to be consistent with the CECL model for originated and purchased non-credit-impaired assets. For AFS debt securities, unrealized credit losses will be recognized as allowances rather than reductions in amortized cost basis and elimination of the other-than-temporary impairment ("OTTI") concept will result in more frequent estimation of credit losses. ASC 326 also requires expanded disclosures on credit risk, including credit quality indicators by vintage of financing receivables. Transitional relief is provided through the ability, upon adoption of the new standard, to elect the fair value option for eligible financial instruments within the scope of the new standard, except for HTM and AFS debt securities. Transition will generally be on a modified retrospective basis, including the election of the fair value option, with a cumulative effect adjustment to beginning retained earnings, except for prospective application of the CECL model for other than temporarily impaired debt securities and purchased credit-impaired assets. The Company adopted the new standard on January 1, 2020. The Company elected the fair value option for all of its outstanding loans receivable, with a cumulative effect adjustment to increase beginning retained earnings by $3.3 million. Under the fair value option, the loans receivable are measured at each reporting period based upon their exit values in an orderly transaction and unrealized gains or losses from changes in fair value are recorded in other gain (loss) on the consolidated statement of operations. The loans are no longer subject to evaluation for impairment through an allowance for loan loss as such losses are captured through fair value changes. Additionally, there is no longer an amortization of loan origination fees or discounts on purchased loans as additional interest income. The Company had no debt securities with unrealized loss in accumulated other comprehensive income ("AOCI") at December 31, 2019 and accordingly, there was no impact upon adoption of the new standard. As it relates to the Company's other accounts receivable that are subject to CECL, the effect of adoption was immaterial. The Company reflected the effect of adoption of CECL by its equity method investee, CLNC, through an adjustment to decrease beginning retained earnings by approximately $8.5 million on January 1, 2020, representing the Company's share of CLNC's cumulative effect adjustment. Fair Value Disclosures In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurements. The ASU requires new disclosures of changes in unrealized gains and losses in other comprehensive income for recurring Level 3 fair value measurements of instruments held at balance sheet date, as well as the range and weighted average or other quantitative information, if more relevant, of significant unobservable inputs for recurring and nonrecurring Level 3 fair values. Certain previously required disclosures are eliminated, specifically around the valuation process required for Level 3 fair values, policy for timing of transfers between levels of the fair value hierarchy, as well as amounts and reason for transfers between Levels 1 and 2. Additionally, the new guidance clarifies or modifies certain existing disclosures, including clarifying that information about measurement uncertainty of Level 3 fair values should be as of reporting date and requiring disclosures of the timing of liquidity events for investments measured under the net asset value ("NAV") practical expedient, but only if the investee has communicated this information or has announced it publicly. The provisions on new disclosures and modification to disclosure of Level 3 measurement uncertainty are to be applied prospectively, while all other provisions are to be applied retrospectively. The Company adopted ASU No. 2018-13 on January 1, 2020. Related Party Guidance for VIEs In November 2018, the FASB issued ASU No. 2018-17, Targeted Improvements to Related Party Guidance for Variable Interest Entities. The ASU amends the VIE guidance to align, throughout the VIE model, the evaluation of a decision maker's or service provider's fee held by a related party, whether or not they are under common control, in both the assessment of whether a fee qualifies as a variable interest and the determination of a primary beneficiary. Specifically, a decision maker or service provider considers interests in a VIE held by a related party under common control only if it has a direct interest in that related party under common control and considers such indirect interest in the VIE held by the related party under common control on a proportionate basis, rather than in its entirety. Transition is generally on a modified retrospective basis, with the cumulative effect adjusted to retained earnings at the beginning of the earliest period presented. The Company adopted ASU No. 2018-17 on January 1, 2020, with no transitional impact upon adoption. Reference Rate Reform In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. The guidance in Topic 848 is optional, the election of which provides temporary relief for the accounting effects on contracts, hedging relationships and other transactions affected by the transition from interbank offered rates (such as the London Interbank Offered Rate ("LIBOR")) that are expected to be discontinued by the end of 2021 to alternative reference rates (such as the Secured Overnight Financing Rate ("SOFR")). Modification of contractual terms to effect the reference rate reform transition on debt, leases, derivatives and other contracts is eligible for relief from modification accounting and accounted for as a continuation of the existing contract. Topic 848 is effective upon issuance through December 31, 2022, and may be applied retrospectively to January 1, 2020. The Company has elected to apply the hedge accounting expedients related to probability and assessment of effectiveness for future LIBOR-indexed cash flows to assume that the index upon which future hedged transactions will be based matches the index on the corresponding derivatives, which preserves existing derivative treatment and presentation. The Company may elect other practical expedients or exceptions as applicable over time as reference rate reform activities occur. Future Application of Accounting Standards Income Tax Accounting In December 2019, the FASB issued ASU No. 2019-12, Simplifying Accounting for Income Taxes. The ASU simplifies accounting for income taxes by eliminating certain exceptions to the general approach in ASC 740, Income Taxes, and clarifies certain aspects of the guidance for more consistent application. The simplifications relate to intraperiod tax allocations when there is a loss in continuing operations and a gain outside of continuing operations, accounting for tax law or tax rate changes and year-to-date losses in interim periods, recognition of deferred tax liability for outside basis difference when investment ownership changes, and accounting for franchise taxes that are partially based on income. The ASU also provides new guidance that clarifies the accounting for transactions resulting in a step-up in tax basis of goodwill, among other changes. Transition is generally prospective, other than the provision related to outside basis difference which is on a modified retrospective basis with cumulative effect adjusted to retained earnings at the beginning of the period adopted, and franchise tax provision which is on either full or modified retrospective. ASU No. 2019-12 is effective January 1, 2021, with early adoption permitted in an interim period, to be applied to all provisions. The Company is currently evaluating the impact of this new guidance. Accounting for Certain Equity Investments In January 2020, the FASB issued ASU No. 2020-01, Clarifying the Interactions between Topic 321 Investments—Equity Securities, Topic 323—Investments Equity Method and Joint Ventures, and Topic 815—Derivatives and Hedging. The ASU clarifies that if as a result of an observable transaction, an equity investment under the measurement alternative is transitioned into equity method and vice versa, an equity method investment is transitioned into measurement alternative, the investment is to be remeasured immediately before and after the transaction, respectively. The ASU also clarifies that certain forward contracts or purchased options to acquire equity securities that are not deemed to be derivatives or in-substance common stock will generally be measured using the fair value principles of ASC 321 before settlement or exercise, and that an entity should not be considering how it will account for the resulting investments upon eventual settlement or exercise. ASU No. 2020-01 is to be applied prospectively, effective January 1, 2021, with early adoption permitted in an interim period. The Company is currently evaluating the impact of this new guidance. Accounting for Convertible Instruments and Contracts on Entity's Own Equity In August 2020, the FASB issued ASU No. 2020-06, Debt—Debt With Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity. The ASU (1) simplifies an issuer’s accounting for convertible instruments as a single unit of account; (2) allows more contracts on an entity’s own equity to qualify for equity classification and more embedded derivatives meeting the derivative scope exception; and (3) simplifies diluted earnings per share (“EPS”) computation. •The guidance eliminates the requirement to separate embedded conversion features in convertible instruments, except for (1) a convertible instrument that contains features requiring bifurcation as a derivative under ASC 815 or (2) a convertible debt instrument that was issued at a substantial premium. •Under the new guidance, certain conditions under Subtopic ASC 815-40 that may result in contracts being settled in cash rather than shares and therefore preclude (1) equity classification for contracts on an entity’s own equity; and (2) embedded derivatives from qualifying for the derivative scope exception, have been removed; for example, the requirement that equity contracts permit settlement in unregistered shares unless such contracts explicitly require settlement in cash if registered shares are unavailable. The guidance also clarifies that freestanding contracts on an entity’s own equity that do not qualify for equity classification under the indexation criteria (ASC 815-4015) or settlement criteria (ASC 815-40-25) are to be measured at fair value through earnings, even if they do not meet the definition of a derivative under ASC 815. •The ASU also amends certain guidance on computation of diluted EPS for convertible instruments and contracts on an entity’s own equity that results in a more dilutive EPS, including (1) requiring the if converted method to be applied for all convertible instruments (the treasury stock method is no longer available), and (2) removing the ability to rebut the presumption of share settlement for contracts that may be settled in cash or stock and that are not liability classified share based payments. •Expanded disclosures are required, including but not limited to, (1) terms and features of convertible instruments and contracts on entity’s own equity; and (2) information about events, conditions, and circumstances that could affect amount or timing of future cash flows related to these instruments or contracts; and in the period of adoption (3) nature of and reason for the change in accounting principle; and (4) effects of the change on EPS. Upon adoption, a one-time election may be made to apply the fair value option for any liability-classified convertible securities. Adoption of the new standard may be made either on a full retrospective approach or a modified retrospective approach, with cumulative effect adjustment recorded to beginning retained earnings. ASU No. 2020-06 is effective January 1, 2022, with early adoption permitted on January 1, 2021. The Company is currently evaluating the effects of this new guidance.

The accompanying unaudited interim financial statements have been prepared in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all information and footnotes required by accounting principles generally accepted in the United States of America (“GAAP”) for complete financial statements. These statements reflect all normal and recurring adjustments which, in the opinion of management, are necessary to present fairly the financial position, results of operations and cash flows of the Company for the interim periods presented. However, the results of operations for the interim period presented are not necessarily indicative of the results that may be expected for the year ending December 31, 2020, or any other future period. These interim financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in, or presented as exhibits to, the Company’s Annual Report on Form 10-K for the year ended December 31, 2019.

The accompanying consolidated financial statements include the accounts of the Company and its controlled subsidiaries. All significant intercompany accounts and transactions have been eliminated. The portions of equity, net income and other comprehensive income of consolidated subsidiaries that are not attributable to the parent are presented separately as amounts attributable to noncontrolling interests in the consolidated financial statements. A substantial portion of noncontrolling interests represents interests held by private investment funds or other investment vehicles managed by the Company and which invest alongside the Company and membership interests in OP primarily held by certain employees of the Company.

Variable Interest Entities—A VIE is an entity that either (i) lacks sufficient equity to finance its activities without additional subordinated financial support from other parties; (ii) whose equity holders lack the characteristics of a controlling financial interest; or (iii) is established with non-substantive voting rights. A VIE is consolidated by its primary beneficiary, which is defined as the party who has a controlling financial interest in the VIE through (a) power to direct the activities of the VIE that most significantly affect the VIE’s economic performance, and (b) obligation to absorb losses or right to receive benefits of the VIE that could be significant to the VIE. The Company also considers interests held by its related parties, including de facto agents. The Company assesses whether it is a member of a related party group that collectively meets the power and benefits criteria and, if so, whether the Company is most closely associated with the VIE. In performing the related party analysis, the Company considers both qualitative and quantitative factors, including, but not limited to: the amount and characteristics of its investment relative to the related party; the Company’s and the related party's ability to control or significantly influence key decisions of the VIE including consideration of involvement by de facto agents; the obligation or likelihood for the Company or the related party to fund operating losses of the VIE; and the similarity and significance of the VIE’s business activities to those of the Company and the related party. The determination of whether an entity is a VIE, and whether the Company is the primary beneficiary, may involve significant judgment, including the determination of which activities most significantly affect the entities’ performance, and estimates about the current and future fair values and performance of assets held by the VIE.

At each reporting period, the Company reassesses whether changes in facts and circumstances cause a change in the status of an entity as a VIE or voting interest entity, and/or a change in the Company's consolidation assessment. Changes in consolidation status are applied prospectively. An entity may be consolidated as a result of this reassessment, in which case, the assets, liabilities and noncontrolling interest in the entity are recorded at fair value upon initial consolidation. Any existing equity interest held by the Company in the entity prior to the Company obtaining control will be remeasured at fair value, which may result in a gain or loss recognized upon initial consolidation. However, if the consolidation represents an asset acquisition of a voting interest entity, the Company's existing interest in the acquired assets, if any, is not remeasured to fair value but continues to be carried at historical cost. The Company may also deconsolidate a subsidiary as a result of this reassessment, which may result in a gain or loss recognized upon deconsolidation depending on the carrying values of deconsolidated assets and liabilities compared to the fair value of any interests retained.

Redeemable Noncontrolling Interests—This represents noncontrolling interests in the Company's digital investment management business and in consolidated open-end funds sponsored by the Company. The noncontrolling interests either have redemption rights that will be triggered upon the occurrence of certain events (Note 16) or have the ability to withdraw all or a portion of their interests from the consolidated open-end funds in cash with advance notice.

Redeemable noncontrolling interests is presented outside of permanent equity. Allocation of net income or loss to redeemable noncontrolling interests is based upon their ownership percentage during the period. The carrying amount of redeemable noncontrolling interests is adjusted to its redemption value at the end of each reporting period to an amount not less than its initial carrying value, except for amounts contingently redeemable which will be adjusted to redemption value only when redemption is probable. Such adjustments will be recognized in additional paid-in capital.

Noncontrolling Interests in Investment Entities—This represents predominantly interests in consolidated investment entities held by private investment funds or retail companies managed by the Company or held by third party joint venture partners. Allocation of net income or loss is generally based upon relative ownership interests held by equity owners in each investment entity, or based upon contractual arrangements that may provide for disproportionate allocation of economic returns among equity interests, including using a hypothetical liquidation at book value basis, where applicable and substantive.

Noncontrolling Interests in Operating Company—This represents membership interests in OP held primarily by certain employees of the Company. Noncontrolling interests in OP are allocated a share of net income or loss in OP based on their weighted average ownership interest in OP during the period. Noncontrolling interests in OP have the right to require OP to redeem part or all of such member’s membership units in OP ("OP Units") for cash based on the market value of an equivalent number of shares of class A common stock at the time of redemption, or at the Company's election as managing member of OP, through issuance of shares of class A common stock (registered or unregistered) on a one-for-one basis. At the end of each reporting period, noncontrolling interests in OP is adjusted to reflect their ownership percentage in OP at the end of the period, through a reallocation between controlling and noncontrolling interests in OP, as applicable.

Definition of a Business—The Company evaluates each purchase transaction to determine whether the acquired assets meet the definition of a business. If substantially all of the fair value of gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets, then the set of transferred assets and activities is not a business. If not, for an acquisition to be considered a business, it would have to include an input and a substantive process that together significantly contribute to the ability to create outputs (i.e., there is a continuation of revenue before and after the transaction). A substantive process is not ancillary or minor, cannot be replaced without significant costs, effort or delay or is otherwise considered unique or scarce. To qualify as a business without outputs, the acquired assets would require an organized workforce with the necessary skills, knowledge and experience that performs a substantive process.

Asset Acquisitions—For acquisitions that are not deemed to be businesses, the assets acquired are recognized based on their cost to the Company as the acquirer and no gain or loss is recognized. The cost of assets acquired in a group is allocated to individual assets within the group based on their relative fair values and does not give rise to goodwill. Transaction costs related to acquisition of assets are included in the cost basis of the assets acquired.

Business Combinations—The Company accounts for acquisitions that qualify as business combinations by applying the acquisition method. Transaction costs related to acquisition of a business are expensed as incurred and excluded from the fair value of consideration transferred. The identifiable assets acquired, liabilities assumed and noncontrolling interests in an acquired entity are recognized and measured at their estimated fair values. The excess of the fair value of consideration transferred over the fair values of identifiable assets acquired, liabilities assumed and noncontrolling interests in an acquired entity, net of fair value of any previously held interest in the acquired entity, is recorded as goodwill. Such valuations require management to make significant estimates and assumptions.

Contingent Consideration—Contingent consideration is classified as a liability or equity, as applicable. Contingent consideration in connection with the acquisition of a business is measured at fair value on acquisition date, and unless classified as equity, is remeasured at fair value each reporting period thereafter until the consideration is settled, with changes in fair value included in net income. Contingent consideration in connection with the acquisition of assets is generally recognized only when the contingency is resolved, as part of the basis of the acquired assets.

If the disposition of a component, being an operating or reportable segment, business unit, subsidiary or asset group, represents a strategic shift that has or will have a major effect on the Company’s operations and financial results, the operating profits or losses of the component when classified as held for sale, and the gain or loss upon disposition of the component, are presented as discontinued operations in the statements of operations.

The pending disposition of the hotel business, composed of the Hospitality segment and the THL Hotel Portfolio in the Other segment, and the disposition of the industrial business in December 2019, including its related management platform, represent strategic shifts that have major effects on the Company’s operations and financial results, and have met the criteria as held for sale and discontinued operations in September 2020 and June 2019, respectively. Accordingly, for all prior periods presented, the related assets and liabilities are presented as assets and liabilities held for disposition on the consolidated balance sheets (Note 8) and the related operating results are presented as income from discontinued operations on the consolidated statements of operations (Note 16).

Reclassifications were made related to discontinued operations as discussed above and to prior period segment reporting presentation as discussed in Note 22. Additionally, interest receivable, which was included in other assets as of December 31, 2019, has been reclassified to be presented as part of loans receivable to conform to current period presentation. These reclassification did not affect the Company's financial position, results of operations or cash flows.

In June 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2016-13, Financial Instruments—Credit Losses, followed by subsequent amendments, which modifies the credit impairment model for financial instruments, and codified as Accounting Standards Codification ("ASC") Topic 326. The multiple existing incurred loss models are replaced with a lifetime current expected credit loss ("CECL") model for off-balance sheet credit exposures that are not unconditionally cancellable by the lender and financial instruments carried at amortized cost, such as loans, loan commitments, held-to-maturity ("HTM") debt securities, financial guarantees, net investment in sales-type and direct financing leases, reinsurance and trade receivables. Targeted changes are also made to the impairment model of available-for-sale ("AFS") debt securities which are not within the scope of CECL.

The CECL model, in estimating expected credit losses over the life of a financial instrument at the time of origination or acquisition, considers historical loss experience, current conditions and the effects of a reasonable and supportable expectation of changes in future macroeconomic conditions. Recognition of allowance for credit losses under the CECL model will generally be accelerated as it encompasses credit losses over the full remaining expected life of the affected financial instruments. For collateralized financial assets, measurement of credit losses under CECL is based on fair value of the collateral if foreclosure is probable or if the collateral-dependent practical expedient is elected for financial assets expected to be repaid substantially through operation or sale of the collateral when the borrower is experiencing financial difficulty. The accounting model for purchased credit-impaired loans and debt securities will be simplified to be consistent with the CECL model for originated and purchased non-credit-impaired assets. For AFS debt securities, unrealized credit

Transitional relief is provided through the ability, upon adoption of the new standard, to elect the fair value option for eligible financial instruments within the scope of the new standard, except for HTM and AFS debt securities. Transition will generally be on a modified retrospective basis, including the election of the fair value option, with a cumulative effect adjustment to beginning retained earnings, except for prospective application of the CECL model for other than temporarily impaired debt securities and purchased credit-impaired assets.

The Company adopted the new standard on January 1, 2020. The Company elected the fair value option for all of its outstanding loans receivable, with a cumulative effect adjustment to increase beginning retained earnings by $3.3 million. Under the fair value option, the loans receivable are measured at each reporting period based upon their exit values in an orderly transaction and unrealized gains or losses from changes in fair value are recorded in other gain (loss) on the consolidated statement of operations. The loans are no longer subject to evaluation for impairment through an allowance for loan loss as such losses are captured through fair value changes. Additionally, there is no longer an amortization of loan origination fees or discounts on purchased loans as additional interest income.

In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurements. The ASU requires new disclosures of changes in unrealized gains and losses in other comprehensive income for recurring Level 3 fair value measurements of instruments held at balance sheet date, as well as the range and weighted average or other quantitative information, if more relevant, of significant unobservable inputs for recurring and nonrecurring Level 3 fair values. Certain previously required disclosures are eliminated, specifically around the valuation process required for Level 3 fair values, policy for timing of transfers between levels of the fair value hierarchy, as well as amounts and reason for transfers between Levels 1 and 2. Additionally, the new guidance clarifies or modifies certain existing disclosures, including clarifying that information about measurement uncertainty of Level 3 fair values should be as of reporting date and requiring disclosures of the timing of liquidity events for investments measured under the net asset value ("NAV") practical expedient, but only if the investee has communicated this information or has announced it publicly. The provisions on new disclosures and modification to disclosure of Level 3 measurement uncertainty are to be applied prospectively, while all other provisions are to be applied retrospectively. The Company adopted ASU No. 2018-13 on January 1, 2020.

In November 2018, the FASB issued ASU No. 2018-17, Targeted Improvements to Related Party Guidance for Variable Interest Entities. The ASU amends the VIE guidance to align, throughout the VIE model, the evaluation of a decision maker's or service provider's fee held by a related party, whether or not they are under common control, in both the assessment of whether a fee qualifies as a variable interest and the determination of a primary beneficiary. Specifically, a decision maker or service provider considers interests in a VIE held by a related party under common control only if it has a direct interest in that related party under common control and considers such indirect interest in the VIE held by the related party under common control on a proportionate basis, rather than in its entirety. Transition is generally on a modified retrospective basis, with the cumulative effect adjusted to retained earnings at the beginning of the earliest period presented. The Company adopted ASU No. 2018-17 on January 1, 2020, with no transitional impact upon adoption.

In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. The guidance in Topic 848 is optional, the election of which provides temporary relief for the accounting effects on contracts, hedging relationships and other transactions affected by the transition from interbank offered rates (such as the London Interbank Offered Rate ("LIBOR")) that are expected to be discontinued by the end of 2021 to alternative reference rates (such as the Secured Overnight Financing Rate ("SOFR")).

Modification of contractual terms to effect the reference rate reform transition on debt, leases, derivatives and other contracts is eligible for relief from modification accounting and accounted for as a continuation of the existing contract. Topic 848 is effective upon issuance through December 31, 2022, and may be applied retrospectively to January 1, 2020. The Company has elected to apply the hedge accounting expedients related to probability and assessment of effectiveness for future LIBOR-indexed cash flows to assume that the index upon which future hedged transactions will be based matches the index on the corresponding derivatives, which preserves existing derivative treatment and presentation. The Company may elect other practical expedients or exceptions as applicable over time as reference rate reform activities occur.

In December 2019, the FASB issued ASU No. 2019-12, Simplifying Accounting for Income Taxes. The ASU simplifies accounting for income taxes by eliminating certain exceptions to the general approach in ASC 740, Income Taxes, and clarifies certain aspects of the guidance for more consistent application. The simplifications relate to intraperiod tax allocations when there is a loss in continuing operations and a gain outside of continuing operations, accounting for tax law or tax rate changes and year-to-date losses in interim periods, recognition of deferred tax liability for outside basis difference when investment ownership changes, and accounting for franchise taxes that are partially based on income. The ASU also provides new guidance that clarifies the accounting for transactions resulting in a step-up in tax basis of goodwill, among other changes. Transition is generally prospective, other than the provision related to outside basis difference which is on a modified retrospective basis with cumulative effect adjusted to retained earnings at the beginning of the period adopted, and franchise tax provision which is on either full or modified retrospective. ASU No. 2019-12 is effective January 1, 2021, with early adoption permitted in an interim period, to be applied to all provisions. The Company is currently evaluating the impact of this new guidance.

In January 2020, the FASB issued ASU No. 2020-01, Clarifying the Interactions between Topic 321 Investments—Equity Securities, Topic 323—Investments Equity Method and Joint Ventures, and Topic 815—Derivatives and Hedging. The ASU clarifies that if as a result of an observable transaction, an equity investment under the measurement alternative is transitioned into equity method and vice versa, an equity method investment is transitioned into measurement alternative, the investment is to be remeasured immediately before and after the transaction, respectively. The ASU also clarifies that certain forward contracts or purchased options to acquire equity securities that are not deemed to be derivatives or in-substance common stock will generally be measured using the fair value principles of ASC 321 before settlement or exercise, and that an entity should not be considering how it will account for the resulting investments upon eventual settlement or exercise. ASU No. 2020-01 is to be applied prospectively, effective January 1, 2021, with early adoption permitted in an interim period. The Company is currently evaluating the impact of this new guidance.

In August 2020, the FASB issued ASU No. 2020-06, Debt—Debt With Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity. The ASU (1) simplifies an issuer’s accounting for convertible instruments as a single unit of account; (2) allows more contracts on an entity’s own equity to qualify for equity classification and more embedded derivatives meeting the derivative scope exception; and (3) simplifies diluted earnings per share (“EPS”) computation.

•Under the new guidance, certain conditions under Subtopic ASC 815-40 that may result in contracts being settled in cash rather than shares and therefore preclude (1) equity classification for contracts on an entity’s own equity; and (2) embedded derivatives from qualifying for the derivative scope exception, have been removed; for example, the requirement that equity contracts permit settlement in unregistered shares unless such contracts explicitly require settlement in cash if registered shares are unavailable. The guidance also clarifies that freestanding contracts on an entity’s own equity that do not qualify for equity classification under the indexation criteria (ASC 815-4015) or settlement criteria (ASC 815-40-25) are to be measured at fair value through earnings, even if they do not meet the definition of a derivative under ASC 815.

•The ASU also amends certain guidance on computation of diluted EPS for convertible instruments and contracts on an entity’s own equity that results in a more dilutive EPS, including (1) requiring the if converted method to be applied for all convertible instruments (the treasury stock method is no longer available), and (2) removing the ability to rebut the presumption of share settlement for contracts that may be settled in cash or stock and that are not liability classified share based payments.

•Expanded disclosures are required, including but not limited to, (1) terms and features of convertible instruments and contracts on entity’s own equity; and (2) information about events, conditions, and circumstances that could affect amount or timing of future cash flows related to these instruments or contracts; and in the period of adoption (3) nature of and reason for the change in accounting principle; and (4) effects of the change on EPS.
