Organization, Consolidation and Presentation of Financial Statements [Abstract]
Business and Organization	Business and Organization Colony Capital, Inc. (together with its consolidated subsidiaries, the "Company" and formerly, Colony NorthStar, Inc. prior to June 25, 2018) is a leading global investment management firm with $43 billion of assets under management. The Company manages capital on behalf of its stockholders, as well as institutional and retail investors in private funds, and traded and non-traded real estate investment trusts ("REITs"). The Company has significant holdings in: (a) the healthcare, industrial and hospitality property sectors; (b) Colony Credit Real Estate, Inc. (NYSE: CLNC) and NorthStar Realty Europe, Corp. (NYSE: NRE), which are both externally managed by subsidiaries of the Company; and (c) various other equity and debt investments. The Company was organized in May 2016 as a Maryland corporation and was formed through a tri-party merger (the "Merger") among Colony Capital, Inc. ("Colony"), NorthStar Asset Management Group Inc. ("NSAM") and NorthStar Realty Finance Corp. ("NRF") in an all-stock exchange on January 10, 2017. The Company elected to be taxed as a REIT under the Internal Revenue Code, for U.S. federal income tax purposes beginning with its taxable year ended December 31, 2017. The Company conducts all of its activities and holds substantially all of its assets and liabilities through its operating subsidiary, Colony Capital Operating Company, LLC (the "Operating Company" or the "OP"). At March 31, 2019, the Company owned 93.9% of the OP, as its sole managing member. The remaining 6.1% is owned primarily by certain employees of the Company as noncontrolling interests. Colony Credit The Company owns an approximate 36.4% interest, on a fully diluted basis, in Colony Credit Real Estate, Inc. ("Colony Credit," formerly Colony NorthStar Credit Real Estate, Inc. prior to June 25, 2018). Colony Credit was formed on January 31, 2018 through a contribution of the CLNY Contributed Portfolio (as described below), represented by the Company's ownership interests ranging from 38% to 100% in certain investment entities ("CLNY Investment Entities"), and a concurrent all-stock merger with NorthStar Real Estate Income Trust, Inc. ("NorthStar I") and NorthStar Real Estate Income II, Inc. ("NorthStar II"), both publicly registered non-traded REITs sponsored and managed by a subsidiary of the Company (the "Combination"). The CLNY Contributed Portfolio comprised the Company's interests in certain commercial real estate loans, net lease properties and limited partnership interests in third party sponsored funds, which represented a select portfolio of U.S. investments within the Company’s other equity and debt segment that were transferable assets consistent with Colony Credit's strategy. Upon closing of the Combination, the Company's management contracts with NorthStar I and NorthStar II were terminated; concurrently, the Company entered into a new management agreement with Colony Credit. Corporate Restructuring Following a strategic review process, in November 2018, the Company announced a corporate restructuring and reorganization plan aimed at reducing its annual compensation and administrative expenses over the next 12 months. The restructuring plan was designed to match resources that further align the Company's increasing focus on its investment management business. In the fourth quarter of 2018, the Company incurred $19.3 million of restructuring costs, predominantly severance costs and accelerated equity-based compensation. In the first quarter of 2019, an additional $0.6 million of restructuring costs were incurred.

Summary of Significant Accounting Policies	Mar. 31, 2019
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 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 generally accepted accounting principles in the United States ("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. Merger The Merger was accounted for under the acquisition method for a business combination as a reverse acquisition, with NSAM as the legal acquirer for certain legal and regulatory matters, and Colony as the accounting acquirer for financial reporting purposes. The financial statements of the Company represent a continuation of the financial information of Colony as the accounting acquirer, except that the equity structure of the Company was adjusted to reflect the equity structure of the legal acquirer, including for any comparative periods presented. 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 a consolidated open-end fund sponsored by the Company. The limited partners in the consolidated open-end fund, who represent noncontrolling interests, generally have the ability to withdraw all or a portion of their interests in cash with 30 days' 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, with such adjustments 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. Reclassifications Beginning in the fourth quarter of 2018, the portion of carried interests earned by the Company that is allocated to employees is presented as carried interest and incentive compensation on the statement of operations. Such amounts had previously been presented as net income attributable to noncontrolling interests in investment entities. For the three months ended March 31, 2018, approximately $0.9 million was reclassified from net income attributable to noncontrolling interests in investment entities to compensation expense in the statement of operations to conform to the current period presentation. The reclassification increased net loss but did not have an impact on net loss attributable to Colony Capital, Inc. and net loss attributable to common stockholders. Accounting Standards Adopted in 2019 Leases In February 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2016-02, Leases, which amended lease accounting standards. ASU 2016-02, along with several clarifying amendments were codified in Accounting Standards Codification ("ASC") Topic 842. The new standard primarily requires lessees to recognize their rights and obligations under most leases on balance sheet, to be capitalized as a right-of-use ("ROU") asset and a corresponding liability for future lease obligations. Targeted changes were made to lessor accounting, primarily to align to the lessee model and the new revenue recognition standard. The Company adopted the new lease standard and related amendments on January 1, 2019 using the modified retrospective method to leases existing or commencing on or after January 1, 2019, with a cumulative effect adjustment to beginning retained earnings. Comparative periods have not been restated and continue to be reported under the standards in effect for those prior periods. ASC 842 limits the definition of initial direct costs to only the incremental costs of obtaining a lease, such as leasing commissions, for both lessee and lessor accounting. Indirect costs such as allocated overhead, certain legal fees and negotiation costs are no longer capitalized under the new standard. The application of ASC 842 on accounting for initial direct costs did not have a material impact on the statement of operations. The Company applied the package of practical expedients, which exempts the Company from having to reassess whether any expired or expiring contracts contain leases, revisit lease classification for any expired or expiring leases and reassess initial direct costs for any existing leases. The Company also elected the practical expedient related to land easements, allowing the Company to carry forward the accounting treatment for land easements on existing agreements. The Company did not, however, elect the hindsight practical expedient to determine the lease terms for existing leases. Lessee Accounting—The Company determines if an arrangement contains a lease and determines the classification of leasing arrangements at inception. A leasing arrangement is classified by the lessee either as a finance lease, which represents a financed purchase of the leased asset, or as an operating lease. The Company's operating leases relate primarily to ground leases acquired with real estate and leases for its corporate offices. For these ground and office leases, the Company has elected the accounting policy to combine lease and related nonlease components as a single lease component. ROU assets and lease liabilities are recognized at the lease commencement date based upon the present value of lease payments over the lease term. The ROU assets also include capitalized initial direct costs offset by lease incentives. Variable lease payments are excluded from the ROU assets and lease liabilities and are recognized in the period in which the obligation for those payments is incurred. The Company makes variable lease payments for: (i) leases with rental payments that are adjusted periodically for inflation or increases in property fair value, (ii) hotel ground leases with rental payments calculated based on a percentage of revenue over contractual levels, or (iii) nonlease services, such as common area maintenance in net leases. Variable lease payments are not included in lease liability and are instead recognized as lease expense when incurred. The Company made the accounting policy election to recognize lease payments from short-term leases on a straight-line basis over the lease term and will not record these leases on the balance sheet. Lease renewal or termination options are factored into the lease asset and lease liability only if it is reasonably certain that the option to extend or the option to terminate would be exercised. As the implicit rate is not readily determinable in most leases, the present value of the remaining lease payments was calculated for each lease using an estimated incremental borrowing rate, which is the interest rate that the Company would have to pay to borrow over the lease term on a collateralized basis. Lease expense is recognized over the lease term based on an effective interest method for finance leases and on a straight-line basis for operating leases. The Company recognized operating lease ROU assets totaling $143.7 million in other assets and corresponding operating lease liabilities totaling $126.8 million in accrued and other liabilities for ground leases in its real estate portfolio and corporate office leases. There was no impact to beginning equity as a result of adoption related to lessee accounting as the difference between the asset and liability balance is attributable to the derecognition of pre-existing balances, including straight-line rent, lease incentives, prepaid or deferred rent and ground lease obligation intangibles. Lessor Accounting—The Company determines if an arrangement contains a lease and determines the classification of leasing arrangements at inception. The Company has operating leases with property tenants that expire at various dates through 2038 with renewal options typically exercised at the lessee's election. Therefore, such options are only recognized once they are deemed reasonably certain, typically at the time the option is exercised. Lease revenue is composed of rental income, which includes the effect of minimum rent increases and rent abatements, resident fee income from healthcare properties, and tenant reimbursements, such as common area maintenance costs and other costs associated with the leases. As lessor, the Company made the accounting policy election to treat the lease and nonlease components in a contract as a single component to the extent that the timing and pattern of transfer are similar for the lease and nonlease components and the lease component qualifies as an operating lease. Nonlease components of tenant reimbursements for net leases and resident fee income qualify for the practical expedient to be combined with their respective lease component and accounted for as a single component under the lease standard as the lease component is predominant. Lease revenue is recognized on a straight-line basis over the remaining lease term and is included in property operating income on the consolidated statements of operations. The Company receives variable lease revenues from tenant reimbursements and resident fee income from ancillary services provided to nursing home residents. Under the new standard, lessors are required to evaluate the collectability of all lease payments based upon the creditworthiness of the lessee. Lease revenue is recognized only to the extent collection of all rents over the life of the lease is determined to be probable. If collection is subsequently determined to no longer be probable, any previously accrued lease revenue that has not been collected is subject to reversal. If collection is subsequently determined to be probable, lease revenue and corresponding receivable would be reestablished to an amount that would have been recognized if collection had always been deemed to be probable. Upon adoption of ASC 842, the Company determined that collection of certain lease receivables, net of existing allowance for bad debts, is not probable and recorded a cumulative adjustment of $4.5 million to reduce beginning equity. Beginning January 1, 2019, the Company also made the accounting policy election to present on a net basis sales and similar taxes assessed by a governmental authority that is imposed on specific lease revenue producing transactions with related collections from lessees. Property taxes and insurance paid directly by lessees to third parties on behalf of the Company are no longer recognized in the statement of operations, while such amounts paid by the Company and reimbursed by lessees continue to be presented as gross property operating income and expenses. Hedge Accounting In August 2017, the FASB issued ASU No. 2017-12, Targeted Improvements to Accounting for Hedging Activities, which simplifies and expands the application of hedge accounting. This standard amends hedge accounting recognition and presentation, including eliminating the requirement to separately measure and present hedge ineffectiveness as well as presenting the entire fair value change of a hedging instrument in the same income statement line as the hedged item. The new guidance also provides alternatives for applying hedge accounting to additional hedging strategies, and easing requirements for effectiveness testing and hedging documentation, although the "highly effective" threshold for a qualifying hedging relationship has not changed. Revised disclosures include tabular disclosures that focus on the effect of hedge accounting by income statement line item. Transition will generally be on a modified retrospective basis applied to existing hedging relationships as of date of adoption, with prospective application for income statement presentation and disclosure, and specific transition elections are available to modify existing hedge documentation. The Company adopted the standard on its effective date of January 1, 2019. Upon adoption, as it relates to the Company’s cash flow and net investment hedges, the Company records the entire change in fair value of the hedging instrument (other than amounts excluded from assessment of hedge effectiveness for net investment hedges) in other comprehensive income and no hedge ineffectiveness is recorded in earnings. Additionally, subsequent to initial quantitative hedge assessment, the Company has elected to perform effectiveness testing qualitatively so long as the Company can reasonably support an expectation that the hedge is highly effective now and in subsequent periods. As the standard allows more flexibility in hedging interest rate risk in cash flow hedges beyond a specified benchmark rate, the Company may be able to designate in the future other contractually specified variable interest rate as the hedged risk, which if effective, could decrease fluctuations in earnings. There was no impact to the Company's financial condition and results of operations upon adoption of this standard. Future Application of Accounting Standards Credit Losses In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses, which amends the credit impairment model for financial instruments. The existing incurred loss model will be replaced with a lifetime current expected credit loss ("CECL") model for financial instruments carried at amortized cost and off-balance sheet credit exposures, such as loans, loan commitments, held-to-maturity ("HTM") debt securities, financial guarantees, net investment in leases, reinsurance and trade receivables, which will generally result in earlier recognition of allowance for losses. For available-for-sale ("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. The accounting model for purchased credit-impaired loans and debt securities will be simplified, including elimination of some of the asymmetrical treatment between credit losses and credit recoveries, to be consistent with the CECL model for originated and purchased non-credit-impaired assets. The existing model for beneficial interests that are not of high credit quality will be amended to conform to the new impairment models for HTM and AFS debt securities. Expanded disclosures on credit risk include credit quality indicators by vintage for financing receivables and net investment in leases. Transition will generally be on a modified retrospective basis, with prospective application for other than temporarily impaired debt securities and purchased credit-impaired assets. ASU No. 2016-13 is effective for fiscal years and interim periods beginning after December 15, 2019. Early adoption is permitted for annual and interim periods beginning after December 15, 2018. The Company expects that recognition of credit losses will generally be accelerated under the CECL model. Evaluation of the impact of this new guidance is ongoing. 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. ASU No. 2018-13 is effective for fiscal years and interim periods beginning after December 15, 2019. Early adoption is permitted in an interim period for which financial statements have not been issued, and may be made only to provisions that eliminate or modify existing disclosures. The adoption of this standard is not expected to have a material effect on the Company's existing disclosures. Variable Interest Entities 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 the evaluation of a decision maker's or service provider's fee in assessing a variable interest with the guidance in the primary beneficiary test. Specifically, indirect interests held by a related party that is under common control will now be considered on a proportionate basis, rather than in their entirety, when assessing whether the fee qualifies as a variable interest. The proportionate basis approach is consistent with the treatment of indirect interests held by a related party under common control when evaluating the primary beneficiary of a VIE. This effectively means that when a decision maker or service provider has an interest in a related party, regardless of whether they are under common control, it will consider that related party's interest in a VIE on a proportionate basis throughout the VIE model, for both the assessment of a variable interest and the determination of a primary beneficiary. Transition is generally on a modified retrospective basis, with the cumulative effect adjusted to retained earnings at the beginning of the earliest period presented. ASU No. 2018-17 is effective for fiscal years and interim periods beginning after December 15, 2019, with early adoption permitted in an interim period for which financial statements have not been issued. The Company is currently evaluating the impact of this new guidance but does not expect the adoption of this standard to have a material effect on its financial condition or results of operations.

Nonaccrual and Past Due Loans

Non-PCI loans, excluding loans carried at fair value, that are 90 days or more past due as to principal or interest, or where reasonable doubt exists as to timely collection, are generally considered nonperforming and placed on nonaccrual status.

The following table provides an aging summary of non-PCI loans held for investment at carrying values before allowance for loan losses:



(In thousands)	Current or Less Than 30 Days Past Due		30-59 Days Past Due		60-89 Days Past Due		90 Days or More Past Due and Nonaccrual		Total Non-PCI Loans

Troubled Debt Restructuring

During the three months ended March 31, 2019 and 2018, there were no loans modified as TDRs, in which the Company provided borrowers, who are experiencing financial difficulties, with various concessions in interest rates, payment terms or default waivers. At both March 31, 2019 and December 31, 2018, the Company had one existing TDR loan that was in maturity default, with a carrying value before allowance for loan loss of $37.8 million, and for which the Company had previously recorded an allowance for loan loss. The Company has no additional lending commitment on this TDR loan.

Non-PCI Impaired Loans

Non-PCI loans, excluding loans carried at fair value, are identified as impaired when it is no longer probable that interest or principal will be collected according to the contractual terms of the original loan agreement. Non-PCI impaired loans include predominantly loans under nonaccrual, performing and nonperforming TDRs, as well as loans in maturity default.

The following table summarizes non-PCI impaired loans:

Purchased Credit-Impaired Loans

PCI loans are acquired loans with evidence of credit quality deterioration for which it is probable at acquisition that the Company will collect less than the contractually required payments. PCI loans are recorded at the initial investment in the loans and accreted to the estimated cash flows expected to be collected as measured at acquisition date. The excess of cash flows expected to be collected, measured as of acquisition date, over the estimated fair value represents the accretable yield and is recognized in interest income over the remaining life of the loan. The difference between contractually required payments as of the acquisition date and the cash flows expected to be collected, which represents the nonaccretable difference, is not recognized as an adjustment of yield, loss accrual or valuation allowance.

Factors that most significantly affect estimates of cash flows expected to be collected, and accordingly the accretable yield, include: (i) estimate of the remaining life of acquired loans which may change the amount of future interest income; (ii) changes to prepayment assumptions; (iii) changes to collateral value assumptions for loans expected to foreclose; and (iv) changes in interest rates on variable rate loans.

There were no PCI loans acquired in the three months ended March 31, 2019 and 2018.

Changes in accretable yield of PCI loans were as follows:



	Three Months Ended March 31,

Effect of changes in foreign exchange rates	(40		)	354
Ending accretable yield	$	7,935		$	29,634

The Company applied either the cash basis or cost recovery method for recognition of interest income on PCI loans with carrying value before allowance for loan losses of $171.6 million at March 31, 2019 and $175.6 million at December 31, 2018, as the Company did not have reasonable expectations of the timing and amount of future cash receipts on these loans.

Allowance for Loan Losses

On a periodic basis, the Company analyzes the extent and effect of any credit migration from underwriting and the initial investment review associated with the performance of a loan and/or value of its underlying collateral, financial and operating capability of the borrower or sponsor, as well as amount and status of any senior loan, where applicable. Specifically, operating results of collateral properties and any cash reserves are analyzed and used to assess whether cash from operations are sufficient to cover debt service requirements currently and into the future, ability of the borrower to refinance the loan, liquidation value of collateral properties, financial wherewithal of any loan guarantors as well as the borrower’s competency in managing and operating the collateral properties. Such analysis is performed at least quarterly, or more often as needed when impairment indicators are present.

Allowance for loan losses represents the estimated probable credit losses inherent in loans held for investment at balance sheet date and is generally measured as the difference between the carrying value of the loan and either the present value of cash flows expected to be collected or an observable market price for the loan.

For PCI loans, provision for loan losses is recorded if it is assessed that decreases in cash flows expected to be collected would result in a decrease in the estimated fair value of the loan below its amortized cost.

The allowance for loan losses and related carrying values of loans held for investment were as follows:

Equity Investments

The Company's equity investments represent noncontrolling equity interests in various entities, including investments for which fair value option was elected.

Equity Method Investments

The Company owns significant interests in Colony Credit and NRE, both publicly-traded REITs that it manages. The Company accounts for its investments under the equity method as it exercises significant influence over operating and financial policies of these entities through a combination of its ownership interest, its role as the external manager and board representation, but does not control these entities. The Company also owns equity method investments that are structured as joint ventures with one or more private funds or other investment vehicles managed by the Company, or with third party joint venture partners. These investment ventures are generally capitalized through equity contributions from the members and/or leveraged through various financing arrangements. The Company elected the fair value option to account for its interests in certain investment ventures and limited partnership interests in third party private equity funds (see Note 11).

The liabilities of the equity method investment entities may only be settled using the assets of these entities and there is no recourse to the general credit of either the Company or the other investors for the obligations of these investment entities. Neither the Company nor the other investors are required to provide financial or other support in excess of their capital commitments. The Company’s exposure to the investment entities is limited to its equity method investment balance.

The Company’s investments accounted for under the equity method, including investments for which fair value option was elected, are summarized below:

⁽¹⁾

The Company's ownership interest represents capital contributed to date and may not be reflective of the Company's economic interest in the entity because of provisions in operating agreements governing various matters, such as classes of partner or member interests, allocations of profits and losses, preferential returns and guaranty of debt. Each equity method investment has been determined to be either a VIE for which the Company was not deemed to be the primary beneficiary or a voting interest entity in which the Company does not have the power to control through a majority of voting interest or through other arrangements.


⁽²⁾	These entities are governed by their respective boards of directors. The Company's role as manager is under the supervision and direction of such entity's board of directors, which includes representatives from the Company but the majority of whom are independent directors.

In connection with the Company's investment in NRE, the Company has an ownership waiver under NRE’s charter which allows the Company to own up to 45% of NRE’s common stock, and to the extent the Company owns more than 25% of NRE’s common stock, the Company will vote the excess shares in the same proportion that the remaining NRE shares not owned by the Company are voted.


⁽³⁾	Some preferred equity investments may not have a stated ownership interest.


⁽⁴⁾	The Company owns varying levels of stated equity interests in certain acquisition, development and construction ("ADC") arrangements as well as profit participation interests without a stated ownership interest in other ADC arrangements.

Impairment of Equity Method Investments

The Company evaluates its equity method investments for other-than-temporary impairment ("OTTI").

Impairment of $2.6 million was recorded in equity method earnings for the three months ended March 31, 2019 based upon a pending sale of the underlying real estate held by the investee.

No OTTI was recognized for the three months ended March 31, 2018. However, impairment of $61.2 million was subsequently recorded during the year ended December 31, 2018. In making its assessment, the Company considered a variety of factors and assumptions specific to each investment, including: offer prices on the Company's investment; expected payoffs from sales of the underlying business of the investee; estimated fair values or sale proceeds of the underlying real estate held by the investee; estimated enterprise value of the investee; or discounted cash flows from the investment.

Colony Credit—In January 2018, the Company deconsolidated the CLNY Contributed Entities and measured its interest in Colony Credit based upon its proportionate share of Colony Credit's estimated fair value at the closing date of the Combination. The excess of fair value over carrying value of the Company's equity interest in the CLNY Investment Entities upon deconsolidation of $9.9 million was recognized in other gain on the consolidated statement of operations in the three months ended March 31, 2018.

Colony Credit’s class A common stock had traded between $15.32 and $23.23 per share since its inception through March 29, 2019, the last trading day of the first quarter. At March 31, 2019, the Company's investment in Colony Credit had a carrying value of $1.03 billion or $21.43 per share, which was approximately $276.7 million in excess of its fair value of $750.7 million based upon the closing stock price of $15.66 per share on March 29, 2019. The Company believes that the carrying value of its investment in Colony Credit is recoverable in the near term and determined that its investment in Colony Credit was not other-than-temporarily impaired as of March 31, 2019. If Colony Credit's common stock continues to trade below the Company's carrying value for a prolonged period of time, an other-than-temporary impairment may be recognized in the future.

Other Equity Investments

Other equity investments that do not qualify for equity method accounting consist of the following:

Marketable Equity Securities—These are equity investment in a third party managed mutual fund and publicly traded equity securities held by a consolidated private open-end fund. The equity securities of the consolidated fund comprise listed stock predominantly in the U.S. and to a lesser extent, in the United Kingdom, and primarily in the financial, real estate and consumer sectors.

Investment Ventures—This represents primarily common equity in the Albertsons/Safeway supermarket chain (with 50% ownership by a co-investment partner) which was initially recorded at cost and prior to 2018, adjusted for distributions in excess of cumulative earnings. There were no adjustments for any impairment or observable price changes.

Private Fund and Retail Company—This represents limited partnership interest in a third party private fund sponsored by an equity method investee and interest in the Company's sponsored non-traded REIT, NorthStar Healthcare Income, Inc. ("NorthStar Healthcare"), for which the Company elected the NAV practical expedient (see Note 11).

Investment Commitments

Investment Ventures—Pursuant to the operating agreements of certain unconsolidated ventures, the venture partners may be required to fund additional amounts for future investments, unfunded lending commitments, ordinary operating costs, guaranties or commitments of the venture entities. The Company also has lending commitments under ADC arrangements which are accounted for as equity method investments. At March 31, 2019, the Company’s share of these commitments was $31.3 million.

Private Funds—At March 31, 2019, the Company has unfunded commitments of $270.8 million to funds sponsored or co-sponsored by the Company that are accounted for as equity method investments.

Debt Securities

The Company's investment in debt securities is composed of N-Star CDO Bonds, classified as available-for-sale ("AFS") and commercial mortgage-backed securities (“CMBS”) held by a consolidated sponsored investment company that is currently in liquidation, accounted for at fair value through earnings.

AFS Debt Securities

The N-Star CDO bonds are investment-grade subordinate bonds retained by NRF from its sponsored collateralized debt obligations ("CDOs"), and CDO bonds originally issued by NRF that were subsequently repurchased by NRF at a discount. These CDOs are collateralized primarily by commercial real estate ("CRE") debt and CRE securities.

The following tables summarize the balance and activities of the N-Star CDO bonds.



			Gross Cumulative Unrealized

March 31, 2019	$	65,732	$	2,180	$	(3,502	)	$	64,410
December 31, 2018	67,513		1,565		(4,951		)	64,127

Results from disposition of N-Star CDO bonds, with realized gains (losses) recorded in other gain (loss), were as follows for the three months ended March 31, 2018. There were no dispositions in the three months ended March 31, 2019.

Impairment of AFS Debt Securities

The following table presents AFS debt securities that have been in a gross unrealized loss position:



	March 31, 2019								December 31, 2018
	Less Than 12 Months				More Than 12 Months				Less Than 12 Months
(In thousands)	Fair Value		Gross Unrealized Loss		Fair Value		Gross Unrealized Loss		Fair Value		Gross Unrealized Loss
N-Star CDO bonds	$	9,194	$	409	$	42,865	$	3,093	$	54,459	$	4,951

The Company performs an assessment, at least quarterly, to determine whether a decline in fair value below

amortized cost of AFS debt securities is other than temporary. OTTI exists when either (i) the holder has the intent to sell

the impaired security, (ii) it is more likely than not the holder will be required to sell the security, or (iii) the holder does not

expect to recover the entire amortized cost of the security. In assessing OTTI and estimating future expected cash flows,

factors considered include, but are not limited to, credit rating of the security, financial condition of the issuer, defaults for

similar securities, performance and value of assets underlying an asset-backed security.

OTTI loss of $0.7 million was recorded during the three months ended March 31, 2019. For the three months ended March 31, 2018, the Company recorded $4.4 million of OTTI loss in other gain (loss) due to an adverse change in expected cash flows on N-Star CDOs, and CMBS held by consolidated N-Star CDOs which were subsequently deconsolidated in the second quarter of 2018. The Company believed that it was not likely that it would recover the amortized cost on these securities prior to selling them.

At March 31, 2019 and December 31, 2018, the Company believed that the N-Star CDOs with unrealized loss in accumulated other comprehensive income were not other than temporarily impaired as it is not more likely than not that the Company will be required to sell the investments before recovery of their amortized cost bases.

⁽¹⁾	The fixed rate recourse debt represents two promissory notes secured by the Company's aircraft.

⁽²⁾

Mortgage debt in the healthcare and other real estate equity segment with an aggregate outstanding principal of $460.2 million at March 31, 2019 and $538.5 million at December 31, 2018 were either in payment default or were not in compliance with certain debt and/or lease covenants. The Company is negotiating with the lenders and the tenants to restructure the debt and leases, as applicable, or otherwise refinance the debt.

⁽³⁾

$1.725 billion outstanding principal of non-recourse fixed rate mortgage debt on certain properties in our U.S. healthcare portfolio is scheduled to mature in December 2019. The Company continues to evaluate its options in connection with the scheduled debt maturity. In the fourth quarter of 2018, the Company had impaired the real estate collateralizing the debt by $109.1 million based on a reassessment of the expected hold period, taking into consideration the upcoming debt maturity (see Note 11). The Company will continue to re-evaluate certain assumptions, including with respect to the hold period of the real estate collateralizing the debt, which could result in further impairment of the underlying real estate in a future period. At March 31, 2019, carrying value of the real estate collateralizing the debt was approximately $2.5 billion.


⁽⁴⁾	Includes $613.7 million of outstanding principal of non-recourse unsecured debt that is supported by an unencumbered asset pool within the light industrial portfolio.

Corporate Credit Facility

On January 10, 2017, the OP entered into an amended and restated credit agreement (the “Credit Agreement”) with several lenders and JPMorgan Chase Bank, N.A. as administrative agent, and Bank of America, N.A. as syndication agent. The Credit Agreement provides a secured revolving credit facility in the maximum principal amount of $1.0 billion, with an option to increase up to $1.5 billion, subject to agreement of existing or substitute lenders to provide the additional loan commitment and satisfaction of customary closing conditions. The credit facility is scheduled to mature in January 2021, with two 6-month extension options, each subject to a fee of 0.10% of the commitment amount upon exercise.

The maximum amount available at any time is limited by a borrowing base of certain investment assets, with the valuation of such investment assets generally determined according to a percentage of adjusted net book value or a multiple of base management fee EBITDA (as defined in the Credit Agreement).

Advances under the Credit Agreement accrue interest at a per annum rate equal to the sum of one-month London Inter-bank Offered Rate ("LIBOR") plus 2.25% or a base rate determined according to a prime rate or federal funds rate plus a margin of 1.25%. The Company pays a commitment fee of 0.25% or 0.35% per annum of the unused amount (0.35% at March 31, 2019), depending upon the amount of facility utilization.

Some of the Company’s subsidiaries guarantee the obligations of the Company under the Credit Agreement. As security for the advances under the Credit Agreement, the Company and some of its affiliates pledged their equity interests in certain subsidiaries through which the Company directly or indirectly owns substantially all of its assets.

The Credit Agreement contains various affirmative and negative covenants, including financial covenants that require the Company to maintain minimum tangible net worth, liquidity levels and financial ratios, as defined in the Credit Agreement.

The Credit Agreement also includes customary events of default, in certain cases subject to reasonable and customary periods to cure. The occurrence of an event of default may result in the termination of the credit facility, accelerate the Company’s repayment obligations, in certain cases limit the Company’s ability to make distributions, and allow the lenders to exercise all rights and remedies available to them with respect to the collateral. There have been no events of default since the inception of the credit facility.

In April 2019, the Credit Agreement was amended to reduce the aggregate commitments available from $1.0 billion to $750 million, and the option to increase the borrowing commitments, subject to agreement by the lenders and customary closing conditions, from $1.5 billion to $1.125 billion. The amendment also provides that the Company may operate at below the minimum fixed charge coverage ratio, as defined in the Credit Agreement, for a reduced valuation of the borrowing base, and establishes a new floor for the minimum fixed charge coverage ratio for fiscal quarters ended March 31, 2019 and thereafter. At March 31, 2019, the Company was in compliance with all of the financial covenants as amended.

Convertible and Exchangeable Senior Notes

Convertible senior notes and exchangeable senior notes (assumed from NRF at fair value in the Merger) are senior unsecured obligations of the Company and are guaranteed by the Company on a senior unsecured basis.

Convertible and exchangeable senior notes issued by the Company and outstanding are as follows:



Description	Issuance Date	Due Date	Interest Rate	Conversion or Exchange Price (per share of common stock)		Conversion or Exchange Ratio ⁽²⁾ (In Shares)	Conversion or Exchange Shares (in thousands)	Earliest Redemption Date	Outstanding Principal

									$	616,105	$	616,105

__________


⁽¹⁾	Represents initial date of issuance of exchangeable senior notes by NRF prior to the Merger.

⁽²⁾

The conversion or exchange rate for convertible and exchangeable senior notes is subject to periodic adjustments to reflect the carried-forward adjustments relating to common stock splits, reverse stock splits, common stock adjustments in connection with spin-offs and cumulative cash dividends paid on the Company's common stock since the issuance of the convertible and exchangeable senior notes. The conversion or exchange ratios are presented in shares of common stock per $1,000 principal of each convertible or exchangeable note.

The convertible and exchangeable senior notes mature on their respective due dates, unless redeemed, repurchased or exchanged prior to such date in accordance with the terms of their respective governing documents. The convertible and exchangeable senior notes are redeemable at a redemption price equal to 100% of their principal amount, plus accrued and unpaid interest up to, but excluding, the redemption date.

The Company may redeem the convertible notes for cash at its option at any time on or after their respective redemption dates if the last reported sale price of the Company's common stock has been at least 130% of the conversion price of the convertible notes then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period ending on, and including, the trading day immediately preceding the date on which the Company provides notice of redemption.

The exchangeable notes may be exchanged for cash, common stock or a combination thereof, at the Company's election, upon the occurrence of specified events, and at any time on or after their respective redemption dates, and on the second business day immediately preceding their maturity dates. The holders of the exchangeable notes have the right, at their option, to require the Company to repurchase the exchangeable notes for cash on certain specific dates in accordance with the terms of their respective governing documents.

Secured and Unsecured Debt

These are primarily investment level financing, which are generally subject to customary non-recourse carve-outs, secured by underlying commercial real estate and mortgage loans receivable.

Junior Subordinated Debt

The junior subordinated debt was assumed by the Company through the Merger at fair value. Prior to the Merger, subsidiaries of NRF, which were formed as statutory trusts, NorthStar Realty Finance Trust I through VIII (the “Trusts”), issued trust preferred securities ("TruPS") in private placement offerings. The sole assets of the Trusts consist of a like amount of junior subordinated notes issued by NRF at the time of the offerings (the "Junior Notes").

The Company may redeem the Junior Notes at par, in whole or in part, for cash, after five years. To the extent the Company redeems the Junior Notes, the Trusts are required to redeem a corresponding amount of TruPS. The ability of the Trusts to pay dividends depends on the receipt of interest payments on the Junior Notes. The Company has the right, pursuant to certain qualifications and covenants, to defer payments of interest on the Junior Notes for up to six consecutive quarters. If payment of interest on the Junior Notes is deferred, the Trusts will defer the quarterly distributions on the TruPS for a corresponding period. Additional interest accrues on deferred payments at the annual rate payable on the Junior Notes, compounded quarterly.

Interest Incurred

Total interest incurred on the Company's debt, including interest capitalized on real estate under development or construction, was as follows:

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivatives

The Company uses derivative instruments to manage the risk of changes in interest rates and foreign exchange rates, arising from both its business operations and economic conditions. Specifically, the Company enters into derivative instruments to manage differences in the amount, timing, and duration of the Company’s known or expected cash receipts and cash payments, the values of which are driven by interest rates, principally relating to the Company’s investments and borrowings. Additionally, the Company’s foreign operations expose the Company to fluctuations in foreign interest rates and exchange rates. The Company enters into derivative instruments to protect the value or fix certain of these foreign denominated amounts in terms of its functional currency, the U.S. dollar. Derivative instruments used in the Company’s risk management activities may be designated as qualifying hedge accounting relationships (“designated hedges”) or otherwise used for economic hedging purposes (“non-designated hedges”).

Fair value of derivative assets and derivative liabilities were as follows:

Designated Net Investment Hedges

The Company’s foreign denominated net investments in subsidiaries or joint ventures were €652.4 million and £232.7 million, or a total of $1.0 billion at March 31, 2019, and €614.0 million and £235.7 million, or a total of $1.0 billion at December 31, 2018.

The Company entered into foreign exchange contracts to hedge the foreign currency exposure of certain investments in foreign subsidiaries or equity method joint ventures, designated as net investment hedges, as follows:


•	forward contracts whereby the Company agrees to sell an amount of foreign currency for an agreed upon amount of U.S. dollars; and


•	foreign exchange collars (caps and floors) without upfront premium costs, which consist of a combination of currency options with single date expirations, whereby the Company gains protection against foreign currency weakening below a specified level and pays for that protection by giving up gains from foreign currency appreciation above a specified level.

Foreign exchange contracts are used to protect the Company’s foreign denominated investments from adverse foreign currency fluctuations, with notional amounts and termination dates based upon the anticipated return of capital from the investments.

Release of accumulated other comprehensive income ("AOCI") related to net investment hedges occurs upon losing a controlling financial interest in an investment or obtaining control over an equity method investment. Upon sale, complete or substantially complete liquidation of an investment in a foreign subsidiary, or partial sale of an equity method investment, the gain or loss on the related net investment hedge is reclassified from AOCI to other gain (loss) as summarized below.

At the end of each quarter, the Company reassesses the effectiveness of its net investment hedges and as appropriate, dedesignates the portion of the derivative notional that is in excess of the beginning balance of its net investments.

Forward Contracts and Performance Swaps

During December 2018 and January 2019, the Company entered into a series of forward contracts on a portfolio of shares in a real estate mutual fund with a counterparty in an aggregate notional amount of $100 million with a one year term to be settled, at the election of the Company, in cash or through delivery of the mutual fund shares. Concurrently with the forward contracts, the Company entered into a series of swap transactions with the same counterparty to pay the return of the Dow Jones U.S. Select REIT Total Return Index. The forward and swap transactions required a combined collateral deposit of $12 million, subject to daily net settlements in net fair value changes in excess of a predetermined threshold.

The forwards and swaps are not designated as hedges for accounting purposes and are subject to fair value adjustments through earnings. For the three months ended March 31, 2019, fair value loss in the forwards of $11.3 million and fair value gain on the swaps of $2.6 million are included in other gain (loss) in the Company’s statement of operations. The Company’s investment in the mutual fund is carried at fair value and is included in equity and debt investments on the balance sheet. Unrealized gain on the mutual fund shares of $11.8 million for the three months ended March 31, 2019 is included in other gain (loss).

Offsetting Assets and Liabilities

The Company enters into agreements subject to enforceable master netting arrangements with its derivative counterparties that allow the Company to offset the settlement of derivative assets and liabilities in the same currency by derivative instrument type or, in the event of default by the counterparty, to offset all derivative assets and liabilities with the same counterparty. The Company has elected not to net derivative asset and liability positions, notwithstanding the conditions for right of offset may have been met. The Company presents derivative assets and liabilities with the same counterparty on a gross basis on the consolidated balance sheets.

The following table sets forth derivative positions where the Company has a right of offset under netting arrangements with the same counterparty.

Fair Value Disclosures [Abstract]

Fair Value

Recurring Fair Values

The table below presents a summary of financial assets and financial liabilities carried at fair value on a recurring basis, including financial instruments for which the fair value option was elected, but excluding financial assets under the NAV practical expedient, categorized into the following three tier hierarchy:

Level 1—Quoted prices (unadjusted) in active markets for identical assets or liabilities.

Level 2—Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in non-active markets, or valuation techniques utilizing inputs that are derived principally from or corroborated by observable data directly or indirectly for substantially the full term of the financial instrument.

Level 3—At least one assumption or input is unobservable and it is significant to the fair value measurement, requiring significant management judgment or estimate.

Equity Method Investments

Equity method investments for which fair value option was elected are carried at fair value on a recurring basis.

Fair values are determined using either discounted cash flow models based on expected future cash flows for income and realization events of the underlying assets, applying revenue multiples, based on transaction price for recently acquired investments, or pending or comparable market sales price on an investment, as applicable. In valuing the Company's investment in third party private equity funds, the Company considers cash flows provided by the general partners of the funds and the implied yields of the funds. The Company has not elected the practical expedient to measure the fair value of its investments in these private equity funds using NAV of the underlying funds. Fair value of equity method investments are classified as Level 3 of the fair value hierarchy, unless investments are valued based on contracted sales prices which are classified as Level 2 of the fair value hierarchy. Changes in fair value of equity method investments under the fair value option are recorded in equity method earnings.

Marketable Equity Securities

Marketable equity securities consist of investment in a third party managed mutual fund and equity securities held by a consolidated fund, which are valued based on listed prices in active markets and classified as Level 1 of the fair value hierarchy.

Debt Securities

N-Star CDO bonds—Fair value of N-Star CDO bonds are determined internally based on recent trades, if any with such securitizations, the Company's knowledge of the underlying collateral and are determined using an internal price interpolated based on third party prices of the senior N-Star CDO bonds of the respective CDOs. All N-Star CDO bonds are classified as Level 3 of the fair value hierarchy.

CMBS of consolidated fund—Fair value is determined based on broker quotes or third party pricing services, classified as Level 2 of the fair value hierarchy.

Derivatives

Derivative instruments consist of interest rate contracts and foreign exchange contracts that are generally traded over-the-counter, and are valued using a third-party service provider, except for exchange traded futures contracts which are Level 1 fair values. Quotations on over-the-counter derivatives are not adjusted and are generally valued using observable inputs such as contractual cash flows, yield curve, foreign currency rates and credit spreads, and are classified as Level 2 of the fair value hierarchy. Although credit valuation adjustments, such as the risk of default, rely on Level 3 inputs, these inputs are not significant to the overall valuation of its derivatives. As a result, derivative valuations in their entirety are classified as Level 2 of the fair value hierarchy.

Other Liabilities—Contingent Consideration for THL Hotel Portfolio

In connection with the consensual foreclosure of the THL Hotel Portfolio (Note 3), contingent consideration is payable to the former preferred equity holder of the borrower in an amount up to $13.0 million. Fair value of the contingent consideration is measured using discounted cash flows based on the probability of the former preferred equity holder receiving such payment.

⁽¹⁾	Represents the directional change in fair value that would result from an increase to the corresponding unobservable input. A decrease to the unobservable input would have the reverse effect. Significant increases or decreases in these inputs in isolation could result in significantly higher or lower fair value measures.


⁽²⁾	Fair value was estimated based on a combination of inputs, namely indicative prices of investments sold by the Company as well as underlying NAV of the respective funds on a quarter lag.


⁽³⁾	Fair value is affected by change in revenue multiple relative to change in rate of revenue growth.


⁽⁴⁾	Valued based upon transaction price of investments recently acquired or offer prices on investments or underlying assets of investee pending sales. Transaction price approximates fair value for an investee engaged in multi-family development during the development stage and pending certificate of occupancy.

Securitized Loans and Securitized Bonds Payable

Prior to May 2018, the Company had elected the fair value option for loans receivable and bonds payable issued by a securitization trust that was consolidated by a N-Star CDO. The N-Star CDO was in turn consolidated by the Company. In May 2018, the Company sold its interests in the N-Star CDO and deconsolidated the N-Star CDO along with the securitization trust consolidated by the N-Star CDO.

Prior to deconsolidation, the Company had adopted the measurement alternative to measure the fair value of the loans receivable held by the securitization trust using the fair value of the bonds payable issued by the securitization trust as the latter represented the more observable fair value. As such, the net gain or loss that was reflected in earnings was limited to changes in fair value of the beneficial interest held by the Company in the previously consolidated securitization trust, and not as a result of a remeasurement of the loans receivable and bonds payable held by third parties in the previously consolidated securitization trust. Fair value of the bonds payable issued by the securitization trust was determined based on broker quotes, which were generally derived from unobservable inputs, and therefore classified as Level 3 of the fair value hierarchy. Correspondingly, the fair value of the loans receivable held by the securitization trust was also classified as Level 3.

Due To Affiliates—Contingent Consideration for Internalization

In connection with the Company's acquisition of the investment management business and operations of its former

manager in April 2015 (the "Internalization"), contingent consideration is payable to certain senior management personnel of the Company. The contingent consideration is payable in a combination of shares of class A common stock, shares of class B common stock and OP Units, measured based on multi-year performance targets for achievement of a contractually-defined funds from operations ("Benchmark FFO") per share target, as well as real estate and non-real estate capital-raising thresholds from the funds management business, to the extent these targets are met. If the minimum performance target for either of these metrics is not met or exceeded, a portion of the contingent consideration paid in respect of the other metric would not be paid out in full.

Prior to June 30, 2018, the contingent consideration had been remeasured at fair value using a third party valuation service provider and classified as Level 3 of the fair value hierarchy, with the change in fair value recorded in other gain (loss). Fair value of the contingent consideration was measured using a Monte Carlo probability simulation model for the Benchmark FFO component and a discounted payout analysis based on probabilities of achieving prescribed targets for the capital-raising component, adjusted for certain targets that had not been met and that had expired. The Company's class A common stock price and related equity volatilities were applied to convert the contingent consideration payout into shares.

At June 30, 2018, the end of the measurement period, the contingent consideration was settled with certain senior management personnel of the Company in a combination of approximately 15,000 shares of class A common stock, 40,000 shares of class B common stock and 1.95 million OP Units. At June 30, 2018, as the contingency was resolved and the number of shares and units to be issued was no longer variable, the payable of $12.5 million, valued based on the closing price of the Company's class A common stock on June 29, 2018, the last trading day of the second quarter, was reclassified out of liabilities into equity, while the associated dividends payable of approximately $6.4 million remained in liabilities. The contingent consideration and associated dividends were fully settled in August 2018.

Investments Carried at Fair Value Using Net Asset Value

Investments in a Company-sponsored non-traded REIT and limited partnership interest in a third party private fund are valued using NAV of the respective vehicles.

Retail Company—real estate	14,312		—		11,990		—

The Company's limited partnership interest in the private fund is not subject to redemption, with distributions to be received through liquidation of underlying investments of the fund. The private fund has an expected life of eight years from its inception in 2017, which may be extended in one year increments up to two years at the discretion of its general partner, an equity method investee of the Company.

No secondary market currently exists for shares of the non-traded REIT and the Company does not currently expect to seek liquidity of its shares of the non-traded REIT. Subject to then-existing market conditions, the board of directors of the non-traded REIT, along with the Company, as sponsor, expects to consider alternatives for providing liquidity to the non-traded REIT shares beginning five years from completion of the offering stage in January 2016, but with no definitive date by which it must do so. In addition, the Company has agreed that any right to have its shares redeemed is subordinated to third party stockholders for so long as its advisory agreement is in effect.

Nonrecurring Fair Values

The Company measures fair value of certain assets on a nonrecurring basis when events or changes in circumstances indicate that the carrying value of the assets may not be recoverable. Adjustments to fair value generally result from the application of lower of amortized cost or fair value accounting for assets held for sale or write-down of asset values due to impairment.

The following table summarizes assets carried at fair value on a nonrecurring basis, measured at the time of impairment.

Impairment is discussed in Note 4 for loans receivable, Note 5 for equity method investments and Note 6 for investment management intangible assets.

Real Estate Held For Sale

At March 31, 2019 and December 31, 2018, real estate held for sale carried at fair value consisted primarily of properties in the European portfolio, valued using either broker price opinions, or a combination of market information, including third-party appraisals and indicative selling prices, adjusted as deemed appropriate by management to account for the inherent risk associated with the properties, and net of 2% to 5% selling cost, classified as Level 3.

Other significant real estate held for sale carried at fair value comprised of certain hotels in the hospitality segment for which the Company previously held a long term hold strategy but in the third quarter of 2018, adopted a sales strategy. These hotels are currently classified as held for sale. Impairment was mostly recorded in 2018 when the hotels were classified as held for investment, based on broker price opinions and net of 3% selling cost, classified as Level 3. In the first quarter of 2019, additional impairment was recorded on certain hotels based on their respective auction prices, classified as Level 2.

Real estate held for sale carried at fair value also included U.S. multi tenant office buildings, valued based on broker quotes net of 2% selling cost, classified as Level 3.

Additionally, at December 31, 2018, certain properties in the THL Hotel Portfolio were impaired and valued based on auction prices or contracted sales prices, net of 2% selling costs, classified as Level 2.

Real Estate Held For Investment

At March 31, 2019, further impairment was recorded on certain properties in the THL Hotel Portfolio that were impacted by the hurricanes in 2017 based upon revised insurance estimates.

At December 31, 2018, real estate held for investment carried at fair value consisted of $282.4 million of healthcare properties that were impaired in the fourth quarter of 2018, driven by shorter hold periods. In the fourth quarter of 2018, the Company had reassessed the hold period on its healthcare properties, taking into consideration the Company's ability to refinance the related debt with upcoming maturities. The Company considered the possibility of shorter hold periods to be an indicator of impairment, among other factors. For properties for which indicators of impairment were identified, the Company compared their carrying values to the undiscounted future net cash flows expected to be generated by these properties over their hold periods, with terminal values estimated based on indicative capitalization rates, adjusted as appropriate for risk characteristics of each property. In performing this analysis, the Company considered the likelihood of possible outcomes under various hold period scenarios depending on its ability to refinance the related debt and applied a probability-weighted approach to different hold periods for each property. For properties where carrying value exceeded undiscounted future net cash flows, the carrying value was determined to not be recoverable. Fair values were estimated for these properties based on the income capitalization approach, using net operating income for each property and applying capitalization rates ranging from 5.5% to 11%. Impairment was measured as the excess of carrying value over fair value, totaling $212.0 million. As the impairment assessment involved subjectivity and judgment, actual results may differ if changes occur in the assumptions used and/or in market conditions and accordingly, negative changes to these variables would result in further impairment charge in the future.

Other significant real estate held for investment carried at fair value at December 31, 2018 pertained to certain healthcare properties and THL Hotel Portfolio that were damaged by hurricanes or fire in 2017, and further impaired in 2018, with impairment based on estimates from insurance appraisers.

Loans Receivable—Loans receivable carried at amortized cost consist of first mortgages, subordinated mortgages and corporate loans, including such loans held by securitization trusts consolidated by the Company. Fair values were determined by comparing the current yield to the estimated yield of newly originated loans with similar credit risk or the market yield at which a third party might expect to purchase such investment; or based on discounted cash flow projections of principal and interest expected to be collected, which includes consideration of the financial standing of the borrower or sponsor as well as operating results of the underlying collateral. Carrying values of loans held for investment carried at amortized cost are presented net of allowance for loan losses, where applicable.

Debt—Fair value of convertible notes was determined using the last trade price in active markets. Fair value of exchangeable notes was determined based on unadjusted quoted prices in a non-active market. Fair values of the corporate credit facility and secured and unsecured debt were estimated by discounting expected future cash outlays at interest rates currently available to the Company for instruments with similar terms and remaining maturities; and such fair values approximated carrying value for floating rate debt with credit spreads that approximate market rates. Fair value of junior subordinated debt was based on unadjusted quotations from a third party valuation firm, with such quotes derived using a combination of internal valuation models, comparable trades in non-active markets and other market data. Fair value of securitization bonds payable was based on quotations from brokers or financial institutions that act as underwriters of the securitized bonds.

Other—The carrying values of cash, due from and to affiliates, other receivables and other payables approximate fair value due to their short term nature, and credit risk, if any, are negligible.

Variable Interest Entities	3 Months Ended
Variable Interest Entities	Mar. 31, 2019
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Variable Interest Entities	Variable Interest Entities A VIE is an entity that lacks sufficient equity to finance its activities without additional subordinated financial support from other parties, or whose equity holders lack the characteristics of a controlling financial interest. The following discusses the Company's involvement with VIEs where the Company is the primary beneficiary and consolidates the VIEs or where the Company is not the primary beneficiary and does not consolidate the VIEs. Operating Subsidiary The Company's operating subsidiary, OP, is a limited liability company that has governing provisions that are the functional equivalent of a limited partnership. The Company holds the majority of membership interest in OP, acts as the managing member of OP and exercises full responsibility, discretion and control over the day-to-day management of OP. The noncontrolling interests in OP do not have substantive liquidation rights, substantive kick-out rights without cause, or substantive participating rights that could be exercised by a simple majority of noncontrolling interest members (including by such a member unilaterally). The absence of such rights, which represent voting rights in a limited partnership equivalent structure, would render OP to be a VIE. The Company, as managing member, has the power to direct the core activities of OP that most significantly affect OP's performance, and through its majority interest in OP, has both the right to receive benefits from and the obligation to absorb losses of OP. Accordingly, the Company is the primary beneficiary of OP and consolidates OP. As the Company conducts its business and holds its assets and liabilities through OP, the total assets and liabilities of OP represent substantially all of the total consolidated assets and liabilities of the Company. Company-Sponsored Private Funds The Company sponsors private funds and other investment vehicles as general partner for the purpose of providing investment management services in exchange for management fees and performance-based fees. These private funds are established as limited partnerships or equivalent structures. Limited partners of the private funds do not have either substantive liquidation rights, or substantive kick-out rights without cause, or substantive participating rights that could be exercised by a simple majority of limited partners or by a single limited partner. Accordingly, the absence of such rights, which represent voting rights in a limited partnership, results in the private funds being considered VIEs. The nature of the Company's involvement with its sponsored funds comprise fee arrangements and equity interests. The fee arrangements are commensurate with the level of management services provided by the Company, and contain terms and conditions that are customary to similar at-market fee arrangements. Consolidated Company-Sponsored Private Fund—The Company currently consolidates a sponsored private fund where it has more than insignificant equity interest in the fund as general partner during the early stages of the fund while additional third party capital is being raised. As a result, the Company is considered to be acting in the capacity of a principal of the sponsored private fund and is therefore the primary beneficiary of the fund. The Company’s exposure is limited to the value of its outstanding investment in the consolidated private fund of $15.3 million at March 31, 2019 and $13.2 million at December 31, 2018. The Company, as general partner, is not obligated to provide any financial support to the consolidated private fund. At March 31, 2019 and December 31, 2018, the consolidated private fund had total assets of $26.6 million and $42.7 million, respectively, made up primarily of marketable equity securities, and total liabilities of $3.8 million and $20.1 million, respectively. Unconsolidated Company-Sponsored Private Funds—The Company does not consolidate its sponsored private funds where it has insignificant direct equity interests or capital commitments to these funds as general partner. The Company may invest alongside certain of its sponsored private funds through joint ventures between the Company and these funds, or the Company may have capital commitments to its sponsored private funds that are satisfied directly through the co-investment joint ventures as an affiliate of the general partner. In these instances, the co-investment joint ventures are consolidated by the Company. As the Company's direct equity interests in its sponsored private funds as general partner absorb insignificant variability, the Company is considered to be acting in the capacity of an agent of these funds and is therefore not the primary beneficiary of these funds. The Company accounts for its equity interests in unconsolidated sponsored private funds under the equity method. The Company's maximum exposure to loss is limited to the carrying value of its investment in the unconsolidated sponsored private funds, totaling $121.2 million at March 31, 2019 and $117.3 million at December 31, 2018, included within equity and debt investments. Securitizations The Company previously securitized loans receivable and CRE debt securities using VIEs. Upon securitization, the Company had retained beneficial interests in the securitization vehicles, usually in the form of equity tranches or subordinate securities. The Company also acquired securities issued by securitization trusts that are VIEs. The securitization vehicles were structured as pass-through entities that receive principal and interest on the underlying mortgage loans and debt securities and distribute those payments to the holders of the notes, certificates or bonds issued by the securitization vehicles. The loans and debt securities were transferred into securitization vehicles such that these assets are restricted and legally isolated from the creditors of the Company, and therefore are not available to satisfy the Company's obligations but only the obligations of the securitization vehicles. The obligations of the securitization vehicles did not have any recourse to the general credit of the Company and its other subsidiaries. Consolidated Securitizations—Prior to June 30, 2018, the Company consolidated securitization trusts for which it had a retained interest and for which it acted as special servicer or collateral manager or otherwise, its interest in the trust may have become the controlling class or directing holder. The Company's role as special servicer, collateral manager or as controlling class or directing holder provided the Company with the ability to direct activities that most significantly impact the economic performance of the securitization vehicles, and together with the interests previously retained by the Company in the securitization vehicles, the Company was deemed to be the primary beneficiary and consolidated these securitization vehicles. As of June 30, 2018, the Company no longer has any consolidated securitization trusts. The Company contributed its interests in three consolidated securitization trusts to Colony Credit upon closing of the Combination and sold its interests in two consolidated securitization trusts to third parties in the second quarter of 2018, resulting in a deconsolidation of these securitization trusts. The Company has retained its role as special servicer or as collateral manager in these securitization trusts. However, the Company may be removed as special servicer by the controlling class interest holders and may be removed as collateral manager through a right of removal provided to the buyer. Additionally, as of June 30, 2018, the underlying assets of the Company's remaining consolidated securitization trust was liquidated. Unconsolidated Securitizations—The Company does not consolidate the assets and liabilities of CDOs in which the Company has an interest but does not retain the collateral management function. NRF had previously delegated the collateral management rights for certain sponsored N-Star CDOs and third party-sponsored CDOs to a third party collateral manager or collateral manager delegate who is entitled to a percentage of the senior and subordinate collateral management fees. The Company continues to receive fees as named collateral manager or collateral manager delegate and retained administrative responsibilities. The Company determined that the fees paid to the third party collateral manager or collateral manager delegate represent a variable interest in the CDOs and that the third party is acting as a principal. The Company concluded that it does not have the power to direct the activities that most significantly impact the economic performance of these CDOs, which include but are not limited to, the ability to sell distressed collateral, and therefore the Company is not the primary beneficiary of such CDOs and does not consolidate these CDOs. The Company’s exposure to loss is limited to its investment in these unconsolidated CDOs, comprising CDO bonds, which aggregate to $65.7 million at March 31, 2019 and $67.5 million at December 31, 2018. Trusts The Company, through the Merger, acquired the Trusts, wholly-owned subsidiaries of NRF formed as statutory trusts. The Trusts issued preferred securities in private placement offerings, and used the proceeds to purchase junior subordinated notes to evidence loans made to NRF (Note 9). The Company owns all of the common stock of the Trusts but does not consolidate the Trusts as the holders of the preferred securities issued by the Trusts are the primary beneficiaries of the Trusts. The Company accounts for its interest in the Trusts under the equity method and its maximum exposure to loss is limited to its investment carrying value of $3.7 million at March 31, 2019 and December 31, 2018, recorded in investments in unconsolidated ventures on the consolidated balance sheet. The junior subordinated notes are recorded as debt on the Company's consolidated balance sheet.

Preferred Stock

In the event of a liquidation or dissolution of the Company, preferred stockholders have priority over common stockholders for payment of dividends and distribution of net assets.

The table below summarizes the preferred stock issued and outstanding at March 31, 2019:



Description	Dividend Rate Per Annum		Initial Issuance Date	Shares Outstanding (in thousands)	Par Value (in thousands)		Liquidation Preference (in thousands)		Earliest Redemption Date

				57,464	$	575	$	1,436,605

All series of preferred stock are at parity with respect to dividends and distributions, including distributions upon liquidation, dissolution or winding up of the Company. Dividends on each series of preferred stock of the Company are payable quarterly in arrears, in the case of the Series B and E preferred stock, in February, May, August and November, and in the case of Series G, H, I and J preferred stock, in January, April, July and October.

Each series of preferred stock is redeemable on or after the earliest redemption date for that series at $25.00 per share plus accrued and unpaid dividends (whether or not declared) exclusively at the Company’s option. The redemption period for each series of preferred stock is subject to the Company’s right under limited circumstances to redeem the preferred stock earlier in order to preserve its qualification as a REIT or upon the occurrence of a change of control (as defined in the articles supplementary relating to each series of preferred stock).

Preferred stock generally does not have any voting rights, except if the Company fails to pay the preferred dividends for six or more quarterly periods (whether or not consecutive). Under such circumstances, the preferred stock will be entitled to vote, together as a single class with any other series of parity stock upon which like voting rights have been conferred and are exercisable, to elect two additional directors to the Company’s board of directors, until all unpaid dividends have been paid or declared and set aside for payment. In addition, certain changes to the terms of any series of preferred stock cannot be made without the affirmative vote of holders of at least two-thirds of the outstanding shares of each such series of preferred stock voting separately as a class for each series of preferred stock.

Redemption of Preferred Stock

In May 2018, the Company redeemed all of its outstanding Series D preferred stock, with settlement in July 2018. The preferred stock redemption was at $25.00 per share liquidation preference plus accrued and unpaid dividends prorated to the redemption date. The deficit of the $25.00 per share liquidation preference over the carrying value of the preferred stock redeemed resulted in an increase to net income attributable to common stockholders.

Common Stock

Except with respect to voting rights, class A common stock and class B common stock have the same rights and privileges and rank equally, share ratably in dividends and distributions, and are identical in all respects as to all matters. Class A common stock has one vote per share and class B common stock has thirty-six and one-half votes per share. This gives the holders of class B common stock a right to vote that reflects the aggregate outstanding non-voting economic interest in the Company (in the form of OP Units) attributable to class B common stock holders and therefore, does not provide any disproportionate voting rights. Class B common stock was issued as consideration in the Company's acquisition in April 2015 of the investment management business and operations of its former manager, which was previously controlled by the Company's Executive Chairman. Each share of class B common stock shall convert automatically into one share of class A common stock if the Executive Chairman or his beneficiaries directly or indirectly transfer beneficial ownership of class B common stock or OP Units held by them, other than to certain qualified transferees, which generally includes affiliates and employees. In addition, each holder of class B common stock has the right, at the holder’s option, to convert all or a portion of such holder’s class B common stock into an equal number of shares of class A common stock.

Common Stock Repurchases

During the three months ended March 31, 2019, the Company repurchased 652,311 shares of its class A common stock, at an aggregate cost of approximately $3.2 million (excluding commissions), or a weighted average price of $4.84 per share pursuant to a $300 million share repurchase program authorized by its board of directors in May 2018, and extended in May 2019 for an additional one year term.

During the year ended December 31, 2018, the Company repurchased 61,417,755 shares of its class A common stock, at an aggregate cost of approximately $350.1 million (excluding commissions), or a weighted average price of $5.70 per share. These repurchases were made pursuant to the Company's $300 million share repurchase program authorized in February 2018 and the May 2018 stock repurchase program.

Dividend Reinvestment and Direct Stock Purchase Plan

The Company's Dividend Reinvestment and Direct Stock Purchase Plan (the “DRIP Plan”) provides existing common stockholders and other investors the opportunity to purchase shares (or additional shares, as applicable) of the Company's class A common stock by reinvesting some or all of the cash dividends received on their shares of the Company's class A common stock or making optional cash purchases within specified parameters. The DRIP Plan involves the acquisition of the Company's class A common stock either in the open market, directly from the Company as newly issued common stock, or in privately negotiated transactions with third parties. There were no shares of class A common stock acquired under the DRIP Plan in the form of new issuances during the three months ended March 31, 2019 and during the year ended December 31, 2018.

Noncontrolling Interests in Investment Entities

These are interests in consolidated investment entities held by private investment funds managed by the Company, or by third party joint venture partners.

The Company's investment in the real estate portfolio of its industrial segment is made alongside third party limited partners through a joint venture consolidated by the Company. Over time, additional capital contributions from limited partners reduce the Company's ownership interest in the joint venture. New limited partners are admitted at the net asset value of the joint venture, based upon valuations determined by independent third parties, at the time of their contributions. For the three months ended March 31, 2019 and 2018, the difference between contributions received and the limited partners' share of the joint venture resulted in an increase to additional paid-in capital of $12.5 million and $5.8 million, respectively.

Noncontrolling Interests in Operating Company

Certain current and past employees of the Company directly or indirectly own interests in OP, presented as noncontrolling interests in the Operating Company. Noncontrolling interests in OP have the right to require OP to redeem part or all of such member’s 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 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.

For the three months ended March 31, 2019, the Company redeemed 2,793 OP Units with the issuance of an equal number of shares of class A common stock on a one-for-one basis.

For the year ended December 31, 2018, the Company redeemed 2,870,422 OP Units, of which 2,074,457 OP Units were redeemed in exchange for an equal number of shares of class A common stock on a one-for-one basis, and 795,965 OP Units were redeemed in exchange for cash of $4.8 million to satisfy tax obligations of OP unitholders. The redemptions included 1.0 million OP units issued for settlement of the contingent consideration in connection with the Internalization (Note 11).

Other fee income ($14 and $0 from affiliates, respectively)	29		70
Total fee income	$	33,500	$	36,842

Base Management Fees—The Company earns base management fees for the day-to-day operations and administration of its managed private funds and traded and non-traded REITs, calculated as follows:


•	Private Funds—generally 1% per annum of the limited partners' net funded capital;


•	Colony Credit—1.5% per annum of Colony Credit's stockholders' equity (as defined in its management agreement).

•

Non-Traded REITs—1.5% per annum of most recently published net asset value (as may be subsequently adjusted for any special distribution) for NorthStar Healthcare, and prior to closing of the Combination on January 31, 2018, 1% to 1.25% per annum of gross assets for NorthStar I and NorthStar II. $2.5 million per quarter of base management fee for NorthStar Healthcare is paid in shares of NorthStar Healthcare common stock at a price per share equal to its most recently published NAV per share (as may be subsequently adjusted for any special distribution); and

•

NRE—a variable fee of 1.5% per annum of NRE's reported European Public Real Estate Association Net Asset Value ("EPRA NAV" as defined in its management agreement) for EPRA NAV up to and including $2.0 billion, and 1.25% per annum for EPRA NAV amounts exceeding $2.0 billion. The management agreement had provided for the Company's management of NRE through at least January 1, 2023. In November 2018, NRE and the Company reached an agreement to terminate the management agreement upon a sale of NRE or, if no sale is consummated, upon internalization of the management of NRE. Such termination will result in a termination payment to the Company of $70 million, less any incentive fees earned through termination. The strategic review committee of NRE's board of directors is in the process of evaluating strategic alternatives to maximize NRE's shareholder value, which includes the potential sale of NRE.

Asset Management Fees—The Company earns asset management fees from its managed private funds, which represents a one-time fee upon closing of each investment, calculated as a fixed percentage, generally 0.5% of the limited partners' net funded capital on each investment.

Acquisition and Disposition Fees—Prior to closing of the Combination on January 31, 2018, the Company earned from NorthStar I and NorthStar II an acquisition fee of 1% of the amount funded or allocated to originate or acquire an investment, and a disposition fee of 1% to 2% of the contractual sales price for disposition of an investment.

Incentive Fees—The Company may earn incentive fees from NRE and Colony Credit, determined based on the performance of the investment vehicles subject to the achievement of minimum return hurdles in accordance with the terms set out in their respective governing agreements. A portion of the incentive fees earned by the Company (generally 40% to 50%) is allocable to senior management, investment professionals and certain other employees of the Company, included in carried interest and incentive fee compensation expense.

Other Fee Income—Other fees include advisory fees from affiliated and/or unaffiliated third parties, and prior to May 2018, selling commission and dealer manager fees through its broker-dealer platform for selling equity in certain classes of shares in the retail companies. In April 2018, the Company combined its broker-dealer platform with a third party to form a joint venture to distribute future investment products. The Company's share of earnings or losses from the joint venture is reflected in equity method earnings.

Equity-Based Compensation

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]

Equity-Based Compensation

The Colony Capital, Inc. 2014 Omnibus Stock Incentive Plan (the "Equity Incentive Plan") provides for the grant of restricted stock, performance stock units ("PSUs"), Long Term Incentive Plan ("LTIP") units, RSUs, deferred stock units ("DSUs"), options, warrants or rights to purchase shares of the Company's common stock, cash incentives and other equity-based awards to the Company's officers, directors (including non-employee directors), employees, co-employees, consultants or advisors of the Company or of any parent or subsidiary who provides services to the Company. Shares reserved for the issuance of awards under the Equity Incentive Plan are subject to equitable adjustment upon the occurrence of certain corporate events, provided that this number automatically increases each January 1st by 2% of the outstanding number of shares of the Company’s class A common stock on the immediately preceding December 31st. At March 31, 2019, an aggregate of 54.4 million shares of the Company's class A common stock were reserved for the issuance of awards under the Equity Incentive Plan.

Restricted Stock—Restricted stock awards relating to the Company's class A common stock are granted to senior executives, directors and certain employees, with a service condition only and generally subject to annual time-based vesting in equal tranches over a three-year period. Restricted stock is entitled to dividends declared and paid on the Company's class A common stock and such dividends are not forfeitable prior to vesting of the award. Restricted stock awards are valued based on the Company's class A common stock price on grant date and equity-based compensation expense is recognized on a straight-line basis over the requisite three-year service period.

Performance Stock Units ("PSUs")—PSUs are granted to senior executives and certain employees, and are subject to both a service condition and market condition. Following the end of the measurement period for the PSUs, the recipients of PSUs who remain employed will vest in, and be issued a number of shares of the Company's class A common stock, ranging from 0% to 200% of the number of PSUs granted, to be determined based upon the performance of the Company's class A common stock either relative to that of a specified peer group or against a target stock price over a three-year measurement period (such measurement metric the "total shareholder return"). In addition, recipients of PSUs who terminate after the first anniversary of the PSU grant are eligible to vest in a portion of the PSU award following the end of the measurement period based on achievement of the total shareholder return metric otherwise applicable to the award. PSUs also contain dividend equivalent rights which entitle the recipients to a payment equal to the amount of dividends that would have been paid on the shares that are ultimately issued at the end of the measurement period. In February 2019, the PSUs issued in 2018 were modified to, among other things, reduce the potential maximum number of shares of the Company’s class A common stock to be issued upon final vesting from 200% to 125% of the number of PSUs granted. The incremental value resulting from the modification was immaterial.

Fair value of PSUs, including dividend equivalent rights, was determined using a Monte Carlo simulation under a risk-neutral premise, with the following assumptions:



	2019 PSU Grant		2018 PSU Grant ⁽⁴⁾
Expected volatility of the Company's class A common stock⁽¹⁾	26.2	%	29.0	%
Expected annual dividend yield⁽²⁾	8.5	%	7.3	%
Risk-free rate (per annum)⁽³⁾	2.4	%	2.1	%

__________


⁽¹⁾	Based upon historical volatility of the Company's stock, and where applicable, a combination of historical volatility and implied volatility on actively traded stock options of a specified peer group.


⁽²⁾	Based upon a combination of historical dividend yields and the current annualized dividends.


⁽³⁾	Based upon the continuously compounded zero-coupon US Treasury yield for the term coinciding with the remaining measurement period of the award as of valuation date.


⁽⁴⁾	Reflects assumptions applied in valuing the award upon modification in February 2019.

Fair value of PSU awards, excluding dividend equivalent rights, is recognized on a straight-line basis over their measurement period as compensation expense, and is not subject to reversal even if the market condition is not achieved. The dividend equivalent right is accounted for as a liability-classified award. The fair value of the dividend equivalent right is recognized as compensation expense on a straight-line basis over the measurement period, and is subject to adjustment to fair value at each reporting period.

LTIP Units—LTIP units are designated as profits interests for federal income tax purposes. Unvested LTIP units do not accrue distributions. Each vested LTIP unit is convertible, at the election of the holder, into one common OP Unit and upon conversion, subject to the redemption terms of OP Units (Note 14). LTIP units are valued based on the Company's class A common stock price on grant date, with equity-based compensation cost recognized on a straight-line basis over the service period and represent an allocation to noncontrolling interest in the Operating Company.

Deferred Stock Units—Certain non-employee directors may elect to defer the receipt of annual base fees and/or restricted stock awards, and in lieu, receive awards of DSUs. DSUs awarded in lieu of annual base fees are fully vested on their grant date, while DSUs awarded in lieu of restricted stock awards vest one year from their grant date. DSUs are entitled to a dividend equivalent, in the form of additional DSUs based on dividends declared and paid on the Company's class A common stock. Any such additional DSUs will also be credited with additional DSUs as cash dividends are paid, subject to the same restrictions and vesting conditions, if any. Upon separation of service from the Company, vested DSUs are to be settled in shares of the Company’s class A common stock or cash, at the option of the Company. Fair value of DSUs are determined based on the price of the Company's class A common stock on grant date and recognized immediately if fully vested upon grant, or on a straight-line basis over the vesting period as equity based compensation expense and equity.

Equity-based compensation expense is as follows:

__________


⁽¹⁾	Represents the number of PSUs granted which does not reflect potential increases or decreases that could result from the final outcome of the total shareholder return at the end of the performance period.

Fair value of equity awards that vested, determined based on their respective fair values at vesting date, was $8.5 million and $105.0 million for the three months ended March 31, 2019 and 2018, respectively.

At March 31, 2019, aggregate unrecognized compensation cost for all unvested equity awards was $53.0 million, which is expected to be recognized over a weighted average period of 2.3 years.

Awards Granted by Managed Companies

Colony Credit and NRE, both managed by the Company, issued restricted stock and performance stock units to the Company and certain of the Company's employees (collectively, "managed company awards"). Colony Credit awards are primarily restricted stock grants that typically vest over a three-year period, subject to service conditions. NRE awards generally have similar terms as the Company's stock awards, except that the NRE performance stock units measure NRE's stock performance against either an absolute total shareholder return threshold or relative to the performance of a specified market index. Employees are entitled to receive shares of NRE common stock if service conditions and/or market conditions are met. Generally, the Company then grants the managed company awards that it receives in its capacity as manager to its employees with substantially the same terms and service requirements. Such grants are made at the discretion of the Company, and the Company may consult with the board of directors or compensation committees of the respective managed companies as to final allocation of awards to its employees.

Managed company awards granted to the Company, pending the grant by the Company to its employees, are recognized based upon their fair value at grant date as an investment in unconsolidated ventures and other liabilities on the consolidated balance sheet. The deferred revenue liability is amortized into other income as the awards vest to the Company. Managed company awards granted to employees, directly by NRE or Colony Credit, or through the Company, are recorded as other asset and other liability, and amortized on a straight-line basis as equity-based compensation expense and as other income, respectively, as the awards vest to the employees. The other asset and other liability associated with managed company awards granted to employees are subject to adjustment to fair value at each reporting period, with changes reflected in equity-based compensation and other income, respectively.

Equity-based compensation expense recognized in relation to managed company awards was $2.8 million and $0.8 million for the three months ended March 31, 2019 and 2018, respectively. A corresponding amount is recognized in other income for managed company awards granted to employees (Note 18). At March 31, 2019, aggregate unrecognized compensation cost for unvested managed company awards was $28.3 million, which is expected to be recognized over a weighted average period of 2.4 years.

Recoverable Expenses—The Company pays organization and offering costs associated with the formation and capital raising of the retail companies and private funds sponsored by the Company, for which the Company recovers from these investment vehicles, up to specified thresholds for certain private funds and up to 1% of proceeds expected to be raised from the offering of retail companies(excluding shares offered pursuant to distribution reinvestment plans).

NorthStar Healthcare Credit Facility—The Company has committed to provide NorthStar Healthcare with an unsecured revolving credit facility at market terms with a maximum principal amount of $35.0 million. The credit facility matures in December 2020, with a six-month extension option. Advances under the credit facility accrue interest at LIBOR plus 3.5%. There is no commitment fee for the unused portion of the facility. The credit facility is intended to provide additional liquidity to NorthStar Healthcare on an as needed basis. At March 31, 2019 and December 31, 2018, there were no outstanding advances under the revolving credit facility.

Liquidating Trust—In connection with the closing of the Combination, a wholly-owned subsidiary of the Company entered into a management services agreement with the liquidating trust that holds the junior participation interest in a loan receivable previously held by NorthStar I that was not transferred to Colony Credit ("NorthStar I Retained Asset"). The Company was engaged as an advisor to service and assist in the potential sale of the NorthStar I Retained Asset, and to provide administrative services to the liquidating trust on such terms and conditions as approved by the trustees for a management fee of 1.25% per annum of the net assets of the liquidating trust. Such fee amount is immaterial for the three months ended March 31, 2019 and 2018.

Sales to Colony Credit—There were no such sales in the three months ended March 31, 2019. In May 2018, the Company sold a preferred equity investment sponsored by the Company's equity method investee, RXR Realty, to Colony Credit at the unpaid principal amount of the investment of $89.1 million. In July 2018, the Company sold to Colony Credit its interest in a subsidiary holding a net lease property in Norway that was partially financed by a non-callable bond for $121.5 million based on an appraised value of the property, resulting in a gain on sale of $28.6 million.

Healthcare Partnership—The Healthcare Partnership was previously formed by NRF with the intention of expanding the Company’s healthcare business (see Note 17). The Healthcare Partnership is entitled to incentive fees ranging from 20% to 25% of distributions above certain hurdles for new and existing healthcare real estate investments held by the Company and a portion of incentive fees earned from NorthStar Healthcare. To date, no incentive fees have been earned by the Healthcare Partnership.

American Healthcare Investors Joint Venture—The Company has an equity method investment in American

Healthcare Investors, LLC (“AHI"). Prior to the termination of its management agreement in October 2018, AHI had provided certain healthcare-focused real estate investment management and related services to the Company and NorthStar Healthcare. For the three months ended March 31, 2018, the Company incurred property management fees and sub-advisory fees to AHI totaling $1.3 million.

Arrangements with Company-Sponsored Private Fund—The Company co-invests alongside a Company-sponsored private fund through joint ventures between the Company and the sponsored private fund. These co-investment joint ventures are consolidated by the Company. The Company has capital commitments, as general partner, directly into the private fund and as an affiliate of the general partner, capital commitments satisfied through co-investment joint ventures. In connection with the Company's commitments as an affiliate of the general partner, the Company is allocated a proportionate share of the costs of the private fund such as financing and administrative costs. Such costs expensed during the three months ended March 31, 2019 and 2018 were immaterial and relate primarily to the Company's share of the fund's operating costs and deferred financing costs on borrowings of the fund.

Equity Awards of NRE and Colony Credit—As discussed in Note 17, NRE and Colony Credit grant equity awards to the Company and certain of the Company's employees, either directly by NRE and Colony Credit, or indirectly through the Company, are recognized as a gross-up of equity-based compensation expense over the vesting period with a corresponding amount in other income.

Investment in Managed Investment Vehicles—Subject to the Company's related party policies and procedures, senior management, investment professionals and certain other employees may participate on a discretionary basis in investment vehicles sponsored by the Company, either directly in the vehicle or indirectly through the general partner entity. These investments are generally not subject to management fees, but otherwise bear their proportionate share of other operating expenses of the investment vehicles. At March 31, 2019 and December 31, 2018, such investments amounted to $6.4 million and $5.7 million, respectively, reflected in redeemable noncontrolling interests and noncontrolling interests on the balance sheet. Their share of net income was $0.5 million for the three months ended March 31, 2019 and was immaterial for the three months ended March 31, 2018.

Corporate Aircraft—The Company, through its subsidiary, Colony Capital Advisors, LLC, has entered into a time sharing agreement with Thomas J. Barrack, Jr., the Company's Executive Chairman and Chief Executive Officer, under which Mr. Barrack may use the Company’s aircraft for personal travel. Under this arrangement, Mr. Barrack pays the Company for personal usage based on the incremental cost to the Company, including direct and indirect variable costs, but in no case more than the maximum reimbursement permitted by the Federal Aviation Regulations under the agreement. Mr. Barrack has reimbursed the Company $0.2 million and $0.1 million for personal flights taken during the three months ended March 31, 2019 and 2018, respectively.

Segment Reporting

Mar. 31, 2019

Segment Reporting [Abstract]

Segment Reporting

The Company conducts its business through the following six reportable segments:

•

Healthcare—The Company's healthcare segment is composed of a diverse portfolio of senior housing, skilled nursing facilities, medical office buildings, and hospitals. The Company earns rental income from senior housing, skilled nursing facilities and hospital assets that are under net leases to single tenants/operators and from medical office buildings which are both single tenant and multi-tenant. In addition, certain of the Company's senior housing properties are managed by operators under a RIDEA (REIT Investment Diversification and Empowerment Act) structure, which effectively allows the Company to gain financial exposure to underlying operations of the facility in a tax efficient manner versus receiving contractual rent under a net lease arrangement.

•

Industrial—The Company's industrial segment is composed of primarily light industrial assets throughout the U.S. Light industrial properties serve as the “last mile” of the logistics chain, which are vital for e-commerce and tenants that require increasingly quick delivery times. In addition, in February 2019, the Company entered into the bulk industrial market as bulk assets remain integral to highly functional distribution networks.


•	Hospitality—The Company's hospitality portfolio is composed of primarily extended stay and select service hotels located mainly in major metropolitan and high-demand suburban markets in the U.S., with the majority affiliated with top hotel brands such as Marriott and Hilton.


•	CLNC—This represents the Company's investment in Colony Credit, a commercial real estate credit REIT with a diverse portfolio consisting primarily of CRE senior mortgage loans, mezzanine loans, preferred equity, debt securities and net lease properties primarily in the U.S.

•

Other Equity and Debt—The Company's other equity and debt segment consists of a diversified group of strategic and non-strategic real estate and real estate-related debt and equity investments. Strategic investments include investments for which the Company acts as a general partner and/or manager (“GP Co-Investments”) and receives various forms of investment management economics on related third-party capital. Non-strategic investments are composed of those investments the Company does not intend to own for the long term including other real estate equity, real estate debt, and net leased assets, among other holdings.

•

Investment Management—The Company's investment management business raises, invests and manages funds on behalf of a diverse set of institutional and individual investors, for which the Company earns management fees, generally based on the amount of assets or capital managed, and contractual incentive fees or carried interest based on the performance of the investment vehicles managed subject to the achievement of minimum return hurdles.

Amounts not allocated to specific segments include corporate level cash and corresponding interest income, fixed assets for administrative use, corporate level financing and related interest expense, income and expense related to cost reimbursement arrangements with certain affiliates, costs in connection with unconsummated investments, compensation expense not directly attributable to reportable segments, corporate level administrative and overhead costs as well as corporate level transaction and integration costs.

The chief operating decision maker assesses the performance of the business based on net income (loss) of each of the reportable segments. The various reportable segments generate distinct revenue streams, consisting of property operating income, interest income and fee income. Costs which are directly attributable, or otherwise can be subjected to a reasonable and systematic allocation, have been allocated to each of the reportable segments.

Summary of Significant Accounting Policies (Policies)	Mar. 31, 2019
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation 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	Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles in the United States ("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.
Merger	Merger The Merger was accounted for under the acquisition method for a business combination as a reverse acquisition, with NSAM as the legal acquirer for certain legal and regulatory matters, and Colony as the accounting acquirer for financial reporting purposes. The financial statements of the Company represent a continuation of the financial information of Colony as the accounting acquirer, except that the equity structure of the Company was adjusted to reflect the equity structure of the legal acquirer, including for any comparative periods presented.
Principles of Consolidation	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	Noncontrolling Interests Redeemable Noncontrolling Interests—This represents noncontrolling interests in a consolidated open-end fund sponsored by the Company. The limited partners in the consolidated open-end fund, who represent noncontrolling interests, generally have the ability to withdraw all or a portion of their interests in cash with 30 days' 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, with such adjustments 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.
Reclassifications	Reclassifications Beginning in the fourth quarter of 2018, the portion of carried interests earned by the Company that is allocated to employees is presented as carried interest and incentive compensation on the statement of operations. Such amounts had previously been presented as net income attributable to noncontrolling interests in investment entities.
Accounting Standards Update	Accounting Standards Adopted in 2019 Leases In February 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2016-02, Leases, which amended lease accounting standards. ASU 2016-02, along with several clarifying amendments were codified in Accounting Standards Codification ("ASC") Topic 842. The new standard primarily requires lessees to recognize their rights and obligations under most leases on balance sheet, to be capitalized as a right-of-use ("ROU") asset and a corresponding liability for future lease obligations. Targeted changes were made to lessor accounting, primarily to align to the lessee model and the new revenue recognition standard. The Company adopted the new lease standard and related amendments on January 1, 2019 using the modified retrospective method to leases existing or commencing on or after January 1, 2019, with a cumulative effect adjustment to beginning retained earnings. Comparative periods have not been restated and continue to be reported under the standards in effect for those prior periods. ASC 842 limits the definition of initial direct costs to only the incremental costs of obtaining a lease, such as leasing commissions, for both lessee and lessor accounting. Indirect costs such as allocated overhead, certain legal fees and negotiation costs are no longer capitalized under the new standard. The application of ASC 842 on accounting for initial direct costs did not have a material impact on the statement of operations. The Company applied the package of practical expedients, which exempts the Company from having to reassess whether any expired or expiring contracts contain leases, revisit lease classification for any expired or expiring leases and reassess initial direct costs for any existing leases. The Company also elected the practical expedient related to land easements, allowing the Company to carry forward the accounting treatment for land easements on existing agreements. The Company did not, however, elect the hindsight practical expedient to determine the lease terms for existing leases. Lessee Accounting—The Company determines if an arrangement contains a lease and determines the classification of leasing arrangements at inception. A leasing arrangement is classified by the lessee either as a finance lease, which represents a financed purchase of the leased asset, or as an operating lease. The Company's operating leases relate primarily to ground leases acquired with real estate and leases for its corporate offices. For these ground and office leases, the Company has elected the accounting policy to combine lease and related nonlease components as a single lease component. ROU assets and lease liabilities are recognized at the lease commencement date based upon the present value of lease payments over the lease term. The ROU assets also include capitalized initial direct costs offset by lease incentives. Variable lease payments are excluded from the ROU assets and lease liabilities and are recognized in the period in which the obligation for those payments is incurred. The Company makes variable lease payments for: (i) leases with rental payments that are adjusted periodically for inflation or increases in property fair value, (ii) hotel ground leases with rental payments calculated based on a percentage of revenue over contractual levels, or (iii) nonlease services, such as common area maintenance in net leases. Variable lease payments are not included in lease liability and are instead recognized as lease expense when incurred. The Company made the accounting policy election to recognize lease payments from short-term leases on a straight-line basis over the lease term and will not record these leases on the balance sheet. Lease renewal or termination options are factored into the lease asset and lease liability only if it is reasonably certain that the option to extend or the option to terminate would be exercised. As the implicit rate is not readily determinable in most leases, the present value of the remaining lease payments was calculated for each lease using an estimated incremental borrowing rate, which is the interest rate that the Company would have to pay to borrow over the lease term on a collateralized basis. Lease expense is recognized over the lease term based on an effective interest method for finance leases and on a straight-line basis for operating leases. The Company recognized operating lease ROU assets totaling $143.7 million in other assets and corresponding operating lease liabilities totaling $126.8 million in accrued and other liabilities for ground leases in its real estate portfolio and corporate office leases. There was no impact to beginning equity as a result of adoption related to lessee accounting as the difference between the asset and liability balance is attributable to the derecognition of pre-existing balances, including straight-line rent, lease incentives, prepaid or deferred rent and ground lease obligation intangibles. Lessor Accounting—The Company determines if an arrangement contains a lease and determines the classification of leasing arrangements at inception. The Company has operating leases with property tenants that expire at various dates through 2038 with renewal options typically exercised at the lessee's election. Therefore, such options are only recognized once they are deemed reasonably certain, typically at the time the option is exercised. Lease revenue is composed of rental income, which includes the effect of minimum rent increases and rent abatements, resident fee income from healthcare properties, and tenant reimbursements, such as common area maintenance costs and other costs associated with the leases. As lessor, the Company made the accounting policy election to treat the lease and nonlease components in a contract as a single component to the extent that the timing and pattern of transfer are similar for the lease and nonlease components and the lease component qualifies as an operating lease. Nonlease components of tenant reimbursements for net leases and resident fee income qualify for the practical expedient to be combined with their respective lease component and accounted for as a single component under the lease standard as the lease component is predominant. Lease revenue is recognized on a straight-line basis over the remaining lease term and is included in property operating income on the consolidated statements of operations. The Company receives variable lease revenues from tenant reimbursements and resident fee income from ancillary services provided to nursing home residents. Under the new standard, lessors are required to evaluate the collectability of all lease payments based upon the creditworthiness of the lessee. Lease revenue is recognized only to the extent collection of all rents over the life of the lease is determined to be probable. If collection is subsequently determined to no longer be probable, any previously accrued lease revenue that has not been collected is subject to reversal. If collection is subsequently determined to be probable, lease revenue and corresponding receivable would be reestablished to an amount that would have been recognized if collection had always been deemed to be probable. Upon adoption of ASC 842, the Company determined that collection of certain lease receivables, net of existing allowance for bad debts, is not probable and recorded a cumulative adjustment of $4.5 million to reduce beginning equity. Beginning January 1, 2019, the Company also made the accounting policy election to present on a net basis sales and similar taxes assessed by a governmental authority that is imposed on specific lease revenue producing transactions with related collections from lessees. Property taxes and insurance paid directly by lessees to third parties on behalf of the Company are no longer recognized in the statement of operations, while such amounts paid by the Company and reimbursed by lessees continue to be presented as gross property operating income and expenses. Hedge Accounting In August 2017, the FASB issued ASU No. 2017-12, Targeted Improvements to Accounting for Hedging Activities, which simplifies and expands the application of hedge accounting. This standard amends hedge accounting recognition and presentation, including eliminating the requirement to separately measure and present hedge ineffectiveness as well as presenting the entire fair value change of a hedging instrument in the same income statement line as the hedged item. The new guidance also provides alternatives for applying hedge accounting to additional hedging strategies, and easing requirements for effectiveness testing and hedging documentation, although the "highly effective" threshold for a qualifying hedging relationship has not changed. Revised disclosures include tabular disclosures that focus on the effect of hedge accounting by income statement line item. Transition will generally be on a modified retrospective basis applied to existing hedging relationships as of date of adoption, with prospective application for income statement presentation and disclosure, and specific transition elections are available to modify existing hedge documentation. The Company adopted the standard on its effective date of January 1, 2019. Upon adoption, as it relates to the Company’s cash flow and net investment hedges, the Company records the entire change in fair value of the hedging instrument (other than amounts excluded from assessment of hedge effectiveness for net investment hedges) in other comprehensive income and no hedge ineffectiveness is recorded in earnings. Additionally, subsequent to initial quantitative hedge assessment, the Company has elected to perform effectiveness testing qualitatively so long as the Company can reasonably support an expectation that the hedge is highly effective now and in subsequent periods. As the standard allows more flexibility in hedging interest rate risk in cash flow hedges beyond a specified benchmark rate, the Company may be able to designate in the future other contractually specified variable interest rate as the hedged risk, which if effective, could decrease fluctuations in earnings. There was no impact to the Company's financial condition and results of operations upon adoption of this standard. Future Application of Accounting Standards Credit Losses In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses, which amends the credit impairment model for financial instruments. The existing incurred loss model will be replaced with a lifetime current expected credit loss ("CECL") model for financial instruments carried at amortized cost and off-balance sheet credit exposures, such as loans, loan commitments, held-to-maturity ("HTM") debt securities, financial guarantees, net investment in leases, reinsurance and trade receivables, which will generally result in earlier recognition of allowance for losses. For available-for-sale ("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. The accounting model for purchased credit-impaired loans and debt securities will be simplified, including elimination of some of the asymmetrical treatment between credit losses and credit recoveries, to be consistent with the CECL model for originated and purchased non-credit-impaired assets. The existing model for beneficial interests that are not of high credit quality will be amended to conform to the new impairment models for HTM and AFS debt securities. Expanded disclosures on credit risk include credit quality indicators by vintage for financing receivables and net investment in leases. Transition will generally be on a modified retrospective basis, with prospective application for other than temporarily impaired debt securities and purchased credit-impaired assets. ASU No. 2016-13 is effective for fiscal years and interim periods beginning after December 15, 2019. Early adoption is permitted for annual and interim periods beginning after December 15, 2018. The Company expects that recognition of credit losses will generally be accelerated under the CECL model. Evaluation of the impact of this new guidance is ongoing. 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. ASU No. 2018-13 is effective for fiscal years and interim periods beginning after December 15, 2019. Early adoption is permitted in an interim period for which financial statements have not been issued, and may be made only to provisions that eliminate or modify existing disclosures. The adoption of this standard is not expected to have a material effect on the Company's existing disclosures. Variable Interest Entities 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 the evaluation of a decision maker's or service provider's fee in assessing a variable interest with the guidance in the primary beneficiary test. Specifically, indirect interests held by a related party that is under common control will now be considered on a proportionate basis, rather than in their entirety, when assessing whether the fee qualifies as a variable interest. The proportionate basis approach is consistent with the treatment of indirect interests held by a related party under common control when evaluating the primary beneficiary of a VIE. This effectively means that when a decision maker or service provider has an interest in a related party, regardless of whether they are under common control, it will consider that related party's interest in a VIE on a proportionate basis throughout the VIE model, for both the assessment of a variable interest and the determination of a primary beneficiary. Transition is generally on a modified retrospective basis, with the cumulative effect adjusted to retained earnings at the beginning of the earliest period presented. ASU No. 2018-17 is effective for fiscal years and interim periods beginning after December 15, 2019, with early adoption permitted in an interim period for which financial statements have not been issued. The Company is currently evaluating the impact of this new guidance but does not expect the adoption of this standard to have a material effect on its financial condition or results of operations.

⁽¹⁾	Represents the directional change in fair value that would result from an increase to the corresponding unobservable input. A decrease to the unobservable input would have the reverse effect. Significant increases or decreases in these inputs in isolation could result in significantly higher or lower fair value measures.


⁽²⁾	Fair value was estimated based on a combination of inputs, namely indicative prices of investments sold by the Company as well as underlying NAV of the respective funds on a quarter lag.


⁽³⁾	Fair value is affected by change in revenue multiple relative to change in rate of revenue growth.


⁽⁴⁾	Valued based upon transaction price of investments recently acquired or offer prices on investments or underlying assets of investee pending sales. Transaction price approximates fair value for an investee engaged in multi-family development during the development stage and pending certificate of occupancy.

Fair value of PSUs, including dividend equivalent rights, was determined using a Monte Carlo simulation under a risk-neutral premise, with the following assumptions:



	2019 PSU Grant		2018 PSU Grant ⁽⁴⁾
Expected volatility of the Company's class A common stock⁽¹⁾	26.2	%	29.0	%
Expected annual dividend yield⁽²⁾	8.5	%	7.3	%
Risk-free rate (per annum)⁽³⁾	2.4	%	2.1	%

__________


⁽¹⁾	Based upon historical volatility of the Company's stock, and where applicable, a combination of historical volatility and implied volatility on actively traded stock options of a specified peer group.


⁽²⁾	Based upon a combination of historical dividend yields and the current annualized dividends.


⁽³⁾	Based upon the continuously compounded zero-coupon US Treasury yield for the term coinciding with the remaining measurement period of the award as of valuation date.


⁽⁴⁾	Reflects assumptions applied in valuing the award upon modification in February 2019.

⁽¹⁾	Represents the directional change in fair value that would result from an increase to the corresponding unobservable input. A decrease to the unobservable input would have the reverse effect. Significant increases or decreases in these inputs in isolation could result in significantly higher or lower fair value measures.


⁽²⁾	Fair value was estimated based on a combination of inputs, namely indicative prices of investments sold by the Company as well as underlying NAV of the respective funds on a quarter lag.


⁽³⁾	Fair value is affected by change in revenue multiple relative to change in rate of revenue growth.


⁽⁴⁾	Valued based upon transaction price of investments recently acquired or offer prices on investments or underlying assets of investee pending sales. Transaction price approximates fair value for an investee engaged in multi-family development during the development stage and pending certificate of occupancy.

Fair value of PSUs, including dividend equivalent rights, was determined using a Monte Carlo simulation under a risk-neutral premise, with the following assumptions:



	2019 PSU Grant		2018 PSU Grant ⁽⁴⁾
Expected volatility of the Company's class A common stock⁽¹⁾	26.2	%	29.0	%
Expected annual dividend yield⁽²⁾	8.5	%	7.3	%
Risk-free rate (per annum)⁽³⁾	2.4	%	2.1	%

__________


⁽¹⁾	Based upon historical volatility of the Company's stock, and where applicable, a combination of historical volatility and implied volatility on actively traded stock options of a specified peer group.


⁽²⁾	Based upon a combination of historical dividend yields and the current annualized dividends.


⁽³⁾	Based upon the continuously compounded zero-coupon US Treasury yield for the term coinciding with the remaining measurement period of the award as of valuation date.


⁽⁴⁾	Reflects assumptions applied in valuing the award upon modification in February 2019.
