Accounting Policies [Abstract]
Significant Accounting Policies	2. Significant Accounting Policies Basis of Presentation These consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (“GAAP”) and in the opinion of management reflect all adjustments, consisting of only normal recurring adjustments, necessary for a fair statement of financial condition, results of operations, and cash flows for the periods presented. The consolidated financial statements include the accounts of the Company’s wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. Consolidation The Company consolidates entities in which it has a controlling financial interest. The Company determines whether it has a controlling financial interest in an entity by first evaluating whether the entity is a voting interest entity (“VOE”) or a variable interest entity (“VIE”). The usual condition for a controlling financial interest in a VOE is ownership of a majority voting interest. If the Company has a majority voting interest in a VOE, the entity is consolidated. The Company has a controlling financial interest in a VIE when the Company has a variable interest that provides it with (i) the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and (ii) the obligation to absorb losses of the VIE or the right to receive benefits from the VIE that could potentially be significant to the VIE. The Company reassesses its evaluation of whether an entity is a VIE when certain reconsideration events occur. Segment and Geographic Information Effective January 1, 2020, the Company, through its subsidiaries in the U.S. and Europe, conducts business as a single operating segment as an ETP sponsor and asset manager which is based upon the Company’s current organizational and management structure, as well as information used by the chief operating decision maker to allocate resources and other factors. Previously, the Company’s financial results were reported in its U.S. Business and International Business reportable segments. Foreign Currency Translation Assets and liabilities of subsidiaries whose functional currency is not the U.S. dollar are translated based on the end of period exchange rates from local currency to U.S. dollars. Results of operations are translated at the average exchange rates in effect during the period. The impact of the foreign currency translation adjustment is included in the Consolidated Statements of Comprehensive (Loss)/Income as a component of other comprehensive (loss)/income. Use of Estimates The preparation of the Company’s consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the balance sheet dates and the reported amounts of revenues and expenses for the periods presented. Actual results could differ materially from those estimates. Revenue Recognition The Company earns substantially all of its revenue in the form of advisory fees from its ETPs and recognizes this revenue over time, as the performance obligation is satisfied. Advisory fees are based on a percentage of the ETPs’ average daily net assets. Progress is measured using the practical expedient under the output method resulting in the recognition of revenue in the amount for which the Company has a right to invoice. Contractual Gold Payments Contractual gold payments are measured and paid monthly based upon the average daily spot price of gold (Note 11). Marketing and Advertising Advertising costs, including media advertising and production costs, are expensed when incurred. Depreciation and Amortization Depreciation is provided for using the straight-line method over the estimated useful lives of the related assets as follows: Equipment 5 years Furniture and fixtures 15 years Leasehold improvements are amortized over the term of their respective leases or service lives of the improvements, whichever is shorter. Fixed assets are recorded at cost less accumulated depreciation and amortization. Stock-Based Awards Accounting for stock-based compensation requires the measurement and recognition of compensation expense for all equity awards based on estimated fair values. Stock-based compensation is measured based on the grant-date fair value of the award and is amortized over the relevant service period. Forfeitures are recognized when they occur. Third-Party Distribution Fees The Company pays a percentage of its advisory fee revenues based on incremental growth in AUM, subject to caps or minimums, to marketing agents to sell WisdomTree ETFs and for including WisdomTree ETFs on third-party customer platforms. Cash and Cash Equivalents The Company considers all highly liquid investments with an original maturity of 90 days or less at the time of purchase to be classified as cash equivalents. The Company maintains deposits with financial institutions in an amount that is in excess of federally insured limits. Accounts Receivable and Allowance for Doubtful Accounts Accounts receivable are customer and other obligations due under normal trade terms. The Company measures credit losses by applying historical loss rates, adjusted for current conditions and supportable forecasts to amounts outstanding using the aging method. Impairment of Long-Lived Assets The Company performs a review for the impairment of long-lived assets when events or changes in circumstances indicate that the estimated undiscounted future cash flows expected to be generated by the assets are less than their carrying amounts or when other events occur which may indicate that the carrying amount of an asset may not be recoverable. Notes Receivable Notes receivable are accounted for on an amortized cost basis, including accrued interest and net of original issue discount and impairments, if any. Interest income is accrued over the term of the notes using the effective interest method. Notes receivable are placed on non-accrual non-accrual Effective January 1, 2020, the Company performs a review for the impairment of the notes receivable and accrued interest on a quarterly basis using the current expected credit loss model and provides for an allowance for credit losses by applying an estimated loss rate to amounts outstanding at the balance sheet date. Previously, credit losses were measured using an incurred loss approach. Securities Owned and Securities Sold, but not yet Purchased (at fair value) Securities owned and securities sold, but not yet purchased are securities classified as either trading or available-for-sale Securities Held-to-Maturity The Company accounts for certain of its securities as held-to-maturity held-to-maturity than-not Held-to-maturity non-accrual held-to-maturity non-accrual Effective January 1, 2020, the Company reviews its portfolio of held-to-maturity Investments in pass-through government-sponsored enterprises (“GSEs”) are determined to have an estimated loss rate of zero due to an implicit U.S. government guarantee. Investments The Company accounts for equity investments that do not have a readily determinable fair value under the measurement alternative prescribed within Accounting Standards Update (“ASU”) 2016-01, Financial Instruments – Recognition and Measurement of Financial Assets and Financial Liabilities issuer. In addition, income is recognized when dividends are received only to the extent they are distributed from net accumulated earnings of the investee. Otherwise, such distributions are considered returns of investment and are recorded as a reduction of the cost of the investment. Goodwill Goodwill is the excess of the fair value of the purchase price over the fair values of the identifiable net assets at the acquisition date. The Company tests goodwill for impairment at least annually and at the time of a triggering event requiring re-evaluation, Goodwill is allocated to the Company’s U.S. Business and European Business components. Effective January 1, 2020, for impairment testing purposes, these components are aggregated as a single reporting unit as they fall under the same operating segment and have similar economic characteristics. Previously, these components were tested separately for impairment when Company was operating as more than one operating segment. Goodwill is assessed for impairment annually on November 30 th Intangible Assets Indefinite-lived intangible assets are tested for impairment at least annually and are also reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Indefinite-lived intangible assets are impaired if their estimated fair values are less than their carrying values. Finite-lived intangible assets, if any, are amortized over their estimated useful life, which is the period over which the assets are expected to contribute directly or indirectly to the future cash flows of the Company. These intangible assets are tested for impairment at the time of a triggering event, if one were to occur. Finite-lived intangible assets may be impaired when the estimated undiscounted future cash flows generated from the assets are less than their carrying amounts. The Company may rely on a qualitative assessment when performing its intangible asset impairment test. Otherwise, the impairment evaluation is performed at the lowest level of reasonably identifiable cash flows independent of other assets. The annual impairment testing date for all of the Company’s intangible assets is November 30 th Leases Effective January 1, 2019, the Company accounts for its lease obligations in accordance with Accounting Standards Codification (“ASC”) Topic 842, Leases right-of-use right-of-use ASC 842 also provides a practical expedient which allows for consideration in a contract to be accounted for as a single lease component rather than allocated between lease and non-lease Upon adoption of ASC 842 on January 1, 2019, the Company applied the transitional practical expedients to its outstanding leases and therefore the Company did not reassess (i) whether any expired or existing contracts are or contain leases; (ii) the lease classification for any expired or existing leases; and (iii) initial direct costs for any existing leases. The Company also elected to apply the new lease requirements at the effective date, rather than the beginning of the earliest comparative period presented. Deferred Consideration – Gold Payments Deferred consideration represents the present value of an obligation to pay gold to a third party into perpetuity and is measured using forward-looking gold prices and a selected discount rate (Note 11). Changes in the fair value of this obligation are reported as (loss)/gain on revaluation of deferred consideration – gold payments on the Company’s Consolidated Statements of Operations. Debt Debt is carried at amortized cost, net of debt issuance costs. Interest expense is recognized using the effective interest method and includes amortization of debt issuance costs over the life of the debt. Earnings per Share Basic earnings per share (“EPS”) is computed by dividing net income available to common stockholders by the weighted-average number of common shares outstanding for the period. Net income available to common stockholders represents net income of the Company reduced by an allocation of earnings to participating securities. The Series A non-voting non-forfeitable two-class Diluted EPS is calculated under the treasury stock and if-converted two-class Income Taxes The Company accounts for income taxes using the liability method, which requires the determination of deferred tax assets and liabilities based on the differences between the financial and tax bases of assets and liabilities using the enacted tax rates in effect for the year in which differences are expected to reverse. Deferred tax assets are reduced by a valuation allowance if, based on the weight of available evidence, it is more-likely-than-not Tax positions are evaluated utilizing a two-step likely-than-not Non-income Going Concern The Company performs a quarterly assessment of its ability to continue as a going concern within one year of the date the financial statements are issued. This assessment include s Recently Issued Accounting Pronouncements In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740) – Simplifying the Accounting for Income Taxes 2019-12). ; ; ; year-to-date non-income-based ; ; ; 2019-12 Recently Adopted Accounting Pronouncements On January 1, 2020, the Company adopted ASU 2016-13, Financial Instruments-Credit Losses (Topic 326) – Measurement of Credit Losses on Financial Instruments 2016-13). with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. In issuing this standard, the FASB is responding to criticism that prior guidance delayed recognition of credit losses. The standard replaced the prior guidance’s “incurred loss” approach with an “expected loss” model. The new model, referred to as the current expected credit loss (“CECL”) model, applies to: (1) financial assets subject to credit losses and measured at amortized cost, and (2) certain off-balance off-balance held-to-maturity) ASU , notes receivable held-to-maturity On January , , the Company adopted ASU 2018-13, Fair Value Measurement (Topic 820) – Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement (ASU 2018-13), which modified the disclosure requirements on fair value measurements, including removing the requirement to disclose the amount of and reasons for transfers between Level and Level of the fair value hierarchy, the policy for timing of transfers between levels and the valuation processes for Level fair value measurements. ASU 2018-13 also added new disclosures including the requirement to disclose (a) the changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level fair value measurements held at the end of the reporting period and (b) the range and weighted average of significant unobservable inputs used to develop Level fair value measurements. This standard only impacted the disclosures pertaining to fair value measurements and were incorporated into the notes to the Company’s consolidated financial statements.

Fair Value Disclosures [Abstract]
Fair Value Measurements	4. Fair Value Measurements The fair value of financial instruments is defined as the price that would be received to sell an asset or paid to transfer a liability (i.e., “the exit price”) in an orderly transaction between market participants at the measurement date. ASC 820, Fair Value Measurements Level 1 – Quoted prices for identical instruments in active markets. Level 2 – Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable. Level 3 – Instruments whose significant drivers are unobservable. The availability of observable inputs can vary from product to product and is affected by a wide variety of factors, including, for example, the type of product, whether the product is new and not yet established in the marketplace, and other characteristics particular to the transaction. To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by management in determining fair value is greatest for instruments categorized in Level 3. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for disclosure purposes, the level in the fair value hierarchy within which the fair value measurement in its entirety falls is determined based on the lowest level input that is significant to the fair value measurement in its entirety. The tables below summarize the categorization of the Company’s assets and liabilities measured at fair value. During the three months ended March 31, 2020 and 2019, there were no transfers between Levels 2 and 3.

Interest on the Term Loan accrues at an annual rate equal to LIBOR, plus up to 2.00% (commencing at LIBOR, plus 1.75%), and interest on the Revolver accrues at an annual rate equal to LIBOR, plus up to 1.50% (commencing at LIBOR, plus 1.25%), in each case, with the exact interest rate margin determined based on the Total Leverage Ratio (as defined below). The Revolver is also subject to a facility fee equal to an annual rate of up to 0.50% of the actual daily amount of the aggregate commitments (whether used or unused) under the Revolver, with the exact facility fee rate determined based on the Total Leverage Ratio. The Credit Facility matures on April 11, 2021. The Term Loan does not amortize and the entire principal balance is due in a single payment on the maturity date. The following table provides a summary of the Company’s outstanding borrowings under the Credit Facility: March 31, 2020 December 31, 2019 Term Loan Revolver (1) Term Loan Revolver (1) Amount borrowed $ 179,000 $ — $ 200,000 $ — Amounts repaid (5,000 ) — (21,000 ) — Amounts outstanding 174,000 — 179,000 — Unamortized issuance costs (2,452 ) 540 (3,044 ) 671 Carrying amount $ 171,548 $ 540 $ 175,956 $ 671 Effective interest rate (2) 5.00 % n/a 5.32 % n/a (1) The available capacity under the Revolver is subject to compliance with the Total Leverage Ratio.

Unamortized issuance costs related to the Revolver of $540 and $671 at March 31, 2020 and December 31, 2019, respectively, are included in other noncurrent assets on the Consolidated Balance Sheet. The fair value of the Company’s debt (classified as Level 2 within the fair value hierarchy) was $168,128 and $176,986 at March 31, 2020 and December 31, 2019, respectively. The credit agreement includes a financial covenant that requires that the Company maintain a Total Leverage Ratio (as defined below), calculated as of the last day of each fiscal quarter, equal to or less than the ratio set forth opposite such fiscal quarter: Fiscal Quarter Ending Total Leverage Ratio March 31, 2020 2.25:1.00 June 30, 2020 2.25:1.00 September 30, 2020 and each subsequent fiscal quarter ending on or before the maturity date 2.00:1.00 Total Leverage Ratio means, as of the last day of any fiscal quarter, the ratio of Consolidated Total Debt of the Company and its restricted subsidiaries (as defined in the credit agreement) as of such date to Consolidated EBITDA of the Company and its restricted subsidiaries (as defined in the credit agreement) for the four consecutive fiscal quarters ended on such date. The Company’s obligations under the Term Loan and Revolver are unconditionally guaranteed by the Company and certain of its subsidiaries and secured by substantially all of the present and future property and assets of the Company and such subsidiaries, in each case, subject to customary exceptions and exclusions. The credit agreement contains customary affirmative covenants for transactions of this type and other affirmative covenants agreed to by the parties, including, among others, the provision of annual and quarterly financial statements and compliance certificates, maintenance of property, insurance, compliance with laws and environmental matters. The credit agreement contains customary negative covenants, including among others, restrictions on the incurrence of indebtedness, granting of liens, making investments and acquisitions, paying dividends, repurchasing equity interests of the Company, entering into affiliate transactions and asset sales. The credit agreement also provides for a number of customary events of default, including, among others, payment, bankruptcy, covenant, representation and warranty, change of control and judgment defaults. The Company is in compliance with its covenants under the credit agreement and is actively exploring refinancing and extension alternatives as the facility matures within approximately the next 12 months.

Preferred Shares On April 10, 2018, the Company filed a Certificate of Designations of Series A Non-Voting as-converted As described in the Certificate of Designations, the Company will not issue, and ETFS Capital does not have the right to require the Company to issue, any shares of common stock upon conversion of the Preferred Shares, if, as a result of such conversion, ETFS Capital (together with certain attribution parties) would beneficially own more than 9.99% of the Company’s outstanding common stock immediately after giving effect to such conversion. In connection with the completion of the ETFS Acquisition, the Company issued 14,750 shares of Series A Non-Voting Convertible Preferred Stock (the “ Preferred Shares ”) , which are convertible into an aggregate of 14,750,000 shares of common stock. The fair value of this consideration was $132,750, based on the closing price of the Company’s common stock on April 10, 2018 of $9.00 per share, the trading day prior to the closing of the acquisition. The following is a summary of the Preferred Share balance: March 31, 2020 December 31, Issuance of Preferred Shares $ 132,750 $ 132,750 Less: Issuance costs (181 ) (181 ) Preferred Shares – carrying value $ 132,569 $ 132,569 Temporary equity classification is required for redeemable instruments for which redemption triggers are outside of the issuer’s control. ETFS Capital has the right to redeem all the Preferred Shares specified to be converted during the period of time specified in the Certificate of Designations in the event that: (a) the number of shares of the Company’s common stock authorized by its certificate of incorporation is insufficient to permit the Company to convert all of the Preferred Shares requested by ETFS Capital to be converted; or (b) ETFS Capital does not, upon completion of a change of control of the Company, receive the same amount per Preferred Share as it would have received had each outstanding Preferred Share been converted into common stock immediately prior to the change of control. However, the Company will not be obligated to make any such redemption payments to the extent such payments would be a breach of any covenant or obligation the Company owes to any of its secured creditors or is otherwise prohibited by applicable law. Any such redemption will be at a price per Preferred Share equal to the dollar volume-weighted average price for a share of common stock for the 30-trading The carrying amount of the Preferred Shares was not adjusted as it was not probable that the Preferred Shares would become redeemable.

Revenues from Contracts with Customers The following table presents the Company’s total revenues from contracts with customers: Three Months Ended March 31, 2020 March 31, 2019 Revenues from contracts with customers: Advisory fees $ 62,950 $ 64,840 Other 924 645 Total operating revenues $ 63,874 $ 65,485 The Company recognizes revenues from contracts with customers when the performance obligation is satisfied, which is when the promised goods or services are transferred to the customer. A good or service is considered to be transferred when the customer obtains control, which is represented by the transfer of rights with regard to the good or service. Transfer of control happens either over time or at a point in time. When a performance obligation is satisfied over time, an entity is required to select a single method of measuring progress for each performance obligation that depicts the entity’s performance in transferring control of goods or services to the customer. Substantially all the Company’s revenues from contracts with customers are derived primarily from investment advisory agreements with related parties (Note 18). These advisory fees are recognized over time, are earned from the Company’s ETPs and are calculated based on a percentage of the ETPs’ average daily net assets. There is no significant judgment in calculating amounts due which are invoiced monthly in arrears and are not subject to any potential reversal. Progress is measured using the practical expedient under the output method resulting in the recognition of revenue in the amount for which the Company has a right to invoice. There are no contract assets or liabilities that arise in connection with the recognition of advisory fee revenue. In addition, there are no costs incurred to obtain or fulfill the contracts with customers, all of which are investment advisory agreements with related parties. Geographic Distribution of Revenue The following table presents the Company’s total revenues geographically as determined by where the respective management companies reside: Three Months Ended March 31, 2020 March 31, 2019 United States $ 39,870 $ 42,623 Jersey 22,525 21,161 Ireland 1,114 1,155 Canada (Note 24) 365 546 Total operating revenues $ 63,874 $ 65,485

Stock-Based Awards	19. Stock-Based Awards On June 20, 2016, the Company’s stockholders approved a new equity award plan under which the Company can issue up to 10,000,000 shares of common stock (less one share for every share granted under prior plans since March 31, 2016 and inclusive of shares available under the prior plans as of March 31, 2016) in the form of stock options and other stock-based awards. The Company also has issued from time to time stock-based awards outside a plan. The Company grants equity awards to employees and directors which include restricted stock awards (“RSAs”), restricted stock units (“RSUs”), performance-based restricted stock units (“PRSUs”) and stock options. Certain awards described below are subject to acceleration under certain conditions. Stock options: Generally issued for terms of ten years and may vest after at least one year of service and have an exercise price equal to the Company’s stock price on the grant date. The Company estimates the fair value of stock options (when granted) using the Black-Scholes option pricing model. RSAs/RSUs: Awards are valued based on the Company’s stock price on grant date and generally vest ratably over three years. PRSUs: These awards cliff vest three years from the grant date and contain a market condition whereby the number of PRSUs ultimately vesting is tied to how the Company’s total shareholder return (“TSR”) compares to a peer group of other publicly traded asset managers over the three-year period. A Monte-Carlo simulation is used to value these awards. The number of PRSUs vesting ranges from 0% to 200% of the target number of PRSUs granted, as follows: • If the relative TSR is below the 25 th • If the relative TSR is at the 25 th • If the relative TSR is above the 25 th th th Stock-based compensation during the three months ended March 31, 2020 and 2019 was $3,239 and $3,072, respectively. A summary of unrecognized stock-based compensation expense and average remaining vesting period is as follows: March 31, 2020 Unrecognized Stock- Average Employees and directors $ 17,760 1.91 A summary of stock-based compensation award activity during the three months ended March 31, 2020 is as follows: Stock RSAs RSUs PRSUs Balance at January 1, 2020 485,536 3,244,558 39,278 232,610 Granted — 1,436,089 32,901 117,013 (1) Exercised/vested (107,000 ) (936,186 ) (27,130 ) — Forfeitures (63,536 ) (23,483 ) (1,993 ) — Balance at March 31, 2020 315,000 3,720,978 43,056 349,623 (1) Represents the target number of PRSUs granted and outstanding. The number of PRSUs that ultimately vest ranges from 0% to 200% of this amount. A Monte-Carlo simulation was used to value these awards using the following assumptions for the Company and the peer group: (i) beginning 90-day average stock prices; (ii) valuation date stock prices; (iii) historical stock price volatilities ranging from 21% to 36% (average 26%); (iv) correlation coefficients based upon the price data used to calculate the historical volatilities; (v) a risk free interest rate of 1.47%; and (vi) an expected dividend yield of 0%

Income Taxes Effective Income Tax Rate – Three Months Ended March 31, 2020 and March 31, 2019 The Company’s effective income tax rate for the three months ended March 31, 2020 of 21.5% resulted in an income tax benefit of $2,371. The Company’s effective income tax rate differs from the federal statutory tax rate of 21% primarily due to a $5,981 reduction in unrecognized tax benefits, a $2,877 non-taxable a valuation allowance on capital losses, non-deductible The Company’s effective income tax rate for the three months ended March 31, 2019 of negative 13.5% resulted in an income tax benefit of $1,049. The Company’s effective income tax rate differs from the federal statutory tax rate of 21% primarily due to a $4,309 reduction in unrecognized tax benefits, a non-taxable Deferred Tax Assets A summary of the components of the Company’s deferred tax assets at March 31, 2020 and December 31, 2019 are as follows: March 31, 2020 December 31, 2019 Deferred tax assets: Capital losses $ 17,002 $ 8,226 Operating lease liabilities 5,295 5,529 NOLs – International 5,233 9,336 Goodwill and intangible assets 1,622 1,671 Stock-based compensation 1,115 1,754 NOLs – U.S. 514 642 Accrued expenses 373 4,054 Outside basis differences 123 123 Other 159 218 Deferred tax assets 31,436 31,553 Deferred tax liabilities: Right of use assets – operating leases 4,189 4,400 Fixed assets and prepaid assets 1,309 1,326 Unrealized gains 717 744 Deferred tax liabilities 6,215 6,470 Total deferred tax assets less deferred tax liabilities 25,221 25,083 Less: valuation allowance (22,358 ) (17,685 ) Deferred tax assets, net $ 2,863 $ 7,398 Net Operating and Capital Losses – U.S The Company’s tax effected net operating losses (“NOLs”) at March 31, 2020 were $514 which expire in 2024. The net operating loss carryforwards have been reduced by the impact of annual limitations described in the Internal Revenue Code Section 382 that arose as a result of an ownership change. The Company’s tax effected capital losses at March 31, 2020 and December 31, 2019 were $17,002 and $8,226, respectively. The change in capital losses is due to the impairment recognized on the Company’s financial interests in AdvisorEngine (Note 7 ) and a capital loss recognized upon sale of the Canadian ETF business. Net Operating Losses – International Certain of the Company’s European subsidiaries generated NOLs outside the U.S. These tax effected NOLs were $5,233 and $9,336 at March 31, 2020 and December 31, 2019, respectively. All of these NOLs at March 31, 2020 are carried forward indefinitely. The reduction in NOLs was due to the sale of the Company’s Canadian ETF business, which occurred on February 19, 2020 (Note 24). Valuation Allowance The Company’s valuation allowance has been established on its net capital losses, international net operating losses and outside basis differences as it is more-likely-than-not Coronavirus Aid, Relief, and Economic Security Act of 2020 (the “CARES Act”) On March 27, 2020, the CARES Act was enacted in response to the COVID-19 non-income Uncertain Tax Positions Tax positions are evaluated utilizing a two-step likely-than-not In connection with the ETFS Acquisition, the Company accrued a liability for uncertain tax positions and interest and penalties at the acquisition date. The table below sets forth the aggregate changes in the balance of these gross unrecognized tax benefits during the three months ended March 31, 2020: Total Unrecognized Interest Penalties Balance on January 1, 2020 $ 32,101 $ 25,998 $ 6,103 Decrease - Lapse of statute of limitations (1) (5,981 ) (4,620 ) (1,361 ) Increases 76 — 76 Foreign currency translation (2) (1,767 ) (1,432 ) (335 ) Balance at March 31, 2020 $ 24,429 $ 19,946 $ 4,483 (1) Recorded as an income tax benefit of $5,981 during the three months ended March 31, 2020, along with an equal and offsetting amount recorded in other losses, net, to recognize a reduction in the indemnification asset. During the three months ended March 31, 2019, an income tax benefit of $4,309 was recorded along with an equal and offsetting amount in other losses, net. (2) The gross unrecognized tax benefits were accrued in British pounds sterling. The Company also recorded an offsetting indemnification asset provided by ETFS Capital as part of its agreement to indemnify the Company for any potential claims, for which an amount is being held in escrow. ETFS Capital has also agreed to provide additional collateral by maintaining a minimum working capital balance up to a stipulated amount. The gross unrecognized tax benefits and interest and penalties totaling $24,429 at March 31, 2020 are included in other non-current At March 31, 2020, there were $24,429 of unrecognized tax benefits (including interest and penalties) that, if recognized, would impact the effective tax rate. The recognition of any unrecognized tax benefits would result in an equal and offsetting adjustment to the indemnification asset which would be recorded in income before taxes due to the indemnity for any potential claims. Income Tax Examinations The Company is subject to U.S. federal income tax as well as income tax of multiple state, local and certain foreign jurisdictions. The Company’s federal tax return and ManJer’s tax return (a Jersey-based subsidiary) for the year ended December 31, 2016 and the Company’s New York state tax return for the years ended December 31, 2015 through 2018 are currently under review by the relevant tax authorities. The Company is indemnified by ETFS Capital for any potential exposure associated with ManJer’s tax return under audit. The Company is not currently under audit in any other income tax jurisdictions. As of March 31, 2020, with few exceptions, the Company was no longer subject to income tax examinations by any taxing authority for years before 2015. Undistributed Earnings of Foreign Subsidiaries Due to the imposition of the Global Intangible Low-Taxed Income (“ GILTI ”) provisions, all unremitted earnings are no longer subject to U.S. federal income tax; however, there could be U.S. state and/or foreign withholding taxes upon distribution of such unremitted earnings. The Company recognizes deferred tax liabilities for withholding taxes that may become payable, where applicable, upon the distribution of earnings and profits from foreign subsidiaries unless considered permanent in duration. As of March 31, 2020, the Company considers all undistributed foreign earnings and profits to be permanent in duration.

Shares Repurchased	22. Shares Repurchased On April 24, 2019, the Company’s Board of Directors extended the term of the Company’s share repurchase program for three years through April 27, 2022. Included under this program are purchases to offset future equity grants made under the Company’s equity plans and purchases made in open market or privately negotiated transactions. This authority may be exercised from time to time, subject to the terms of the credit agreement described below and regulatory considerations. The timing and actual number of shares repurchased will depend on a variety of factors including price, corporate and regulatory requirements, market conditions and other corporate liquidity requirements and priorities. The repurchase program may be suspended or terminated at any time without prior notice. Shares repurchased under this program are returned to the status of authorized and unissued on the Company’s books and records. In addition, the Company entered into a credit agreement (Note 12) which contains customary negative covenants, including, among others, a covenant which may restrict the Company’s ability to repurchase equity interests. Share repurchases only are permitted to the extent the Total Leverage Ratio (as defined in the credit agreement) does not exceed 1.75 to 1.00 and no event of default (as defined in the credit agreement) has occurred and is continuing at the time the share repurchase is made. However, the Company’s ability to purchase shares of its common stock withheld pursuant to the terms of equity awards granted to employees to satisfy tax withholding obligations is not restricted. During the three months ended March 31, 2020 and March 31, 2019, the Company repurchased 385,399 shares and 311,213 shares of its common stock, respectively, under this program for an aggregate cost of $1,495 and $2,005, respectively.

Significant Accounting Policies (Policies)	Mar. 31, 2020
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation These consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (“GAAP”) and in the opinion of management reflect all adjustments, consisting of only normal recurring adjustments, necessary for a fair statement of financial condition, results of operations, and cash flows for the periods presented. The consolidated financial statements include the accounts of the Company’s wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.
Consolidation	Consolidation The Company consolidates entities in which it has a controlling financial interest. The Company determines whether it has a controlling financial interest in an entity by first evaluating whether the entity is a voting interest entity (“VOE”) or a variable interest entity (“VIE”). The usual condition for a controlling financial interest in a VOE is ownership of a majority voting interest. If the Company has a majority voting interest in a VOE, the entity is consolidated. The Company has a controlling financial interest in a VIE when the Company has a variable interest that provides it with (i) the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and (ii) the obligation to absorb losses of the VIE or the right to receive benefits from the VIE that could potentially be significant to the VIE. The Company reassesses its evaluation of whether an entity is a VIE when certain reconsideration events occur.
Segment and Geographic Information	Segment and Geographic Information Effective January 1, 2020, the Company, through its subsidiaries in the U.S. and Europe, conducts business as a single operating segment as an ETP sponsor and asset manager which is based upon the Company’s current organizational and management structure, as well as information used by the chief operating decision maker to allocate resources and other factors. Previously, the Company’s financial results were reported in its U.S. Business and International Business reportable segments.
Foreign Currency Translation	Foreign Currency Translation Assets and liabilities of subsidiaries whose functional currency is not the U.S. dollar are translated based on the end of period exchange rates from local currency to U.S. dollars. Results of operations are translated at the average exchange rates in effect during the period. The impact of the foreign currency translation adjustment is included in the Consolidated Statements of Comprehensive (Loss)/Income as a component of other comprehensive (loss)/income.
Use of Estimates	Use of Estimates The preparation of the Company’s consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the balance sheet dates and the reported amounts of revenues and expenses for the periods presented. Actual results could differ materially from those estimates.
Revenue Recognition	Revenue Recognition The Company earns substantially all of its revenue in the form of advisory fees from its ETPs and recognizes this revenue over time, as the performance obligation is satisfied. Advisory fees are based on a percentage of the ETPs’ average daily net assets. Progress is measured using the practical expedient under the output method resulting in the recognition of revenue in the amount for which the Company has a right to invoice.
Contractual Gold Payments	Contractual Gold Payments Contractual gold payments are measured and paid monthly based upon the average daily spot price of gold (Note 11).
Marketing and Advertising	Marketing and Advertising Advertising costs, including media advertising and production costs, are expensed when incurred.
Depreciation and Amortization	Depreciation and Amortization Depreciation is provided for using the straight-line method over the estimated useful lives of the related assets as follows: Equipment 5 years Furniture and fixtures 15 years Leasehold improvements are amortized over the term of their respective leases or service lives of the improvements, whichever is shorter. Fixed assets are recorded at cost less accumulated depreciation and amortization.
Stock-Based Awards	Stock-Based Awards Accounting for stock-based compensation requires the measurement and recognition of compensation expense for all equity awards based on estimated fair values. Stock-based compensation is measured based on the grant-date fair value of the award and is amortized over the relevant service period. Forfeitures are recognized when they occur.
Third-Party Distribution Fees	Third-Party Distribution Fees The Company pays a percentage of its advisory fee revenues based on incremental growth in AUM, subject to caps or minimums, to marketing agents to sell WisdomTree ETFs and for including WisdomTree ETFs on third-party customer platforms.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers all highly liquid investments with an original maturity of 90 days or less at the time of purchase to be classified as cash equivalents. The Company maintains deposits with financial institutions in an amount that is in excess of federally insured limits.
Accounts Receivable and Allowance for Doubtful Accounts	Accounts Receivable and Allowance for Doubtful Accounts Accounts receivable are customer and other obligations due under normal trade terms. The Company measures credit losses by applying historical loss rates, adjusted for current conditions and supportable forecasts to amounts outstanding using the aging method.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets The Company performs a review for the impairment of long-lived assets when events or changes in circumstances indicate that the estimated undiscounted future cash flows expected to be generated by the assets are less than their carrying amounts or when other events occur which may indicate that the carrying amount of an asset may not be recoverable.
Notes Receivable	Notes Receivable Notes receivable are accounted for on an amortized cost basis, including accrued interest and net of original issue discount and impairments, if any. Interest income is accrued over the term of the notes using the effective interest method. Notes receivable are placed on non-accrual non-accrual Effective January 1, 2020, the Company performs a review for the impairment of the notes receivable and accrued interest on a quarterly basis using the current expected credit loss model and provides for an allowance for credit losses by applying an estimated loss rate to amounts outstanding at the balance sheet date. Previously, credit losses were measured using an incurred loss approach.
Securities Owned and Securities Sold, but not yet Purchased (at fair value)	Securities Owned and Securities Sold, but not yet Purchased (at fair value) Securities owned and securities sold, but not yet purchased are securities classified as either trading or available-for-sale
Securities Held-to-Maturity	Securities Held-to-Maturity The Company accounts for certain of its securities as held-to-maturity held-to-maturity than-not Held-to-maturity non-accrual held-to-maturity non-accrual Effective January 1, 2020, the Company reviews its portfolio of held-to-maturity Investments in pass-through government-sponsored enterprises (“GSEs”) are determined to have an estimated loss rate of zero due to an implicit U.S. government guarantee.
Investments	Investments The Company accounts for equity investments that do not have a readily determinable fair value under the measurement alternative prescribed within Accounting Standards Update (“ASU”) 2016-01, Financial Instruments – Recognition and Measurement of Financial Assets and Financial Liabilities issuer. In addition, income is recognized when dividends are received only to the extent they are distributed from net accumulated earnings of the investee. Otherwise, such distributions are considered returns of investment and are recorded as a reduction of the cost of the investment.
Goodwill	Goodwill Goodwill is the excess of the fair value of the purchase price over the fair values of the identifiable net assets at the acquisition date. The Company tests goodwill for impairment at least annually and at the time of a triggering event requiring re-evaluation, Goodwill is allocated to the Company’s U.S. Business and European Business components. Effective January 1, 2020, for impairment testing purposes, these components are aggregated as a single reporting unit as they fall under the same operating segment and have similar economic characteristics. Previously, these components were tested separately for impairment when Company was operating as more than one operating segment. Goodwill is assessed for impairment annually on November 30 th
Intangible Assets	Intangible Assets Indefinite-lived intangible assets are tested for impairment at least annually and are also reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Indefinite-lived intangible assets are impaired if their estimated fair values are less than their carrying values. Finite-lived intangible assets, if any, are amortized over their estimated useful life, which is the period over which the assets are expected to contribute directly or indirectly to the future cash flows of the Company. These intangible assets are tested for impairment at the time of a triggering event, if one were to occur. Finite-lived intangible assets may be impaired when the estimated undiscounted future cash flows generated from the assets are less than their carrying amounts. The Company may rely on a qualitative assessment when performing its intangible asset impairment test.

The standard replaced the prior guidance’s “incurred loss” approach with an “expected loss” model. The new model, referred to as the current expected credit loss (“CECL”) model, applies to: (1) financial assets subject to credit losses and measured at amortized cost, and (2) certain off-balance off-balance held-to-maturity) ASU , notes receivable held-to-maturity On January , , the Company adopted ASU 2018-13, Fair Value Measurement (Topic 820) – Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement (ASU 2018-13), which modified the disclosure requirements on fair value measurements, including removing the requirement to disclose the amount of and reasons for transfers between Level and Level of the fair value hierarchy, the policy for timing of transfers between levels and the valuation processes for Level fair value measurements. ASU 2018-13 also added new disclosures including the requirement to disclose (a) the changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level fair value measurements held at the end of the reporting period and (b) the range and weighted average of significant unobservable inputs used to develop Level fair value measurements. This standard only impacted the disclosures pertaining to fair value measurements and were incorporated into the notes to the Company’s consolidated financial statements.
