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 VOE or VIE when certain reconsideration events occur.
Segment and Geographic Information | Segment and Geographic Information 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.
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 Income/(Loss) 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 10 ).
Marketing and Advertising | Marketing and Advertising Marketing and advertising costs, including media advertising and production costs, are expensed when incurred.
Depreciation and Amortization | Depreciation and Amortization Depreciation and amortization is provided for using the straight-line method over the estimated useful lives of the related assets as follows:
Equipment |  |  | 3 to 5 years |
Internally-developed software |  |  | 3 years |
The assets listed above 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 assets under management (“AUM”), subject to caps or minimums, to marketing agents to sell WisdomTree ETFs and for including WisdomTree ETFs on third-party customer platforms and recognizes these expenses as incurred.
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 | Accounts Receivable Accounts receivable are customer and other obligations due under normal trade terms. The Company measures credit losses, if any, by applying historical loss rates, adjusted for current conditions and reasonable 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.
Financial Instruments Owned and Financial Instruments Sold, but Not yet Purchased (at Fair Value) | Financial Instruments Owned and Financial Instruments Sold, but Not yet Purchased (at Fair Value) Financial instruments owned and financial instruments sold, but not yet purchased are financial instruments classified as either trading or available-for-sale (“AFS”). These financial instruments are recorded on their trade date and are measured at fair value. All equity instruments that have readily determinable fair values are classified by the Company as trading. Debt instruments are classified based primarily on the Company’s intent to hold or sell the instrument. Changes in the fair value of debt instruments classified as trading and AFS are reported in other income/(expenses) and other comprehensive income, respectively, in the period the change occurs. Debt instruments classified as AFS are assessed for impairment on a quarterly basis and an estimate for credit loss is provided when the fair value of the AFS debt instrument is below its amortized cost basis. Credit-related impairments are recognized in earnings with a corresponding adjustment to the instrument’s amortized cost basis if the Company intends to sell the impaired AFS debt instrument or it is more likely than not the Company will be required to sell the instrument before recovering its amortized cost basis. Other credit-related impairments are recognized as an allowance with a corresponding adjustment to earnings. Impairments resulting from noncredit-related factors are recognized in other comprehensive income. Amounts recorded in other comprehensive income are reclassified into earnings upon sale of the AFS debt instrument using the specific identification method.
Securities Held-to-Maturity | Securities Held-to-Maturity The Company accounts for certain of its securities as held-to-maturity on a trade date basis, which are recorded at amortized cost. For held-to-maturity securities, the Company has the intent and ability to hold these securities to maturity and it is not more-likely-than-not that the Company will be required to sell these securities before recovery of their amortized cost bases, which may be maturity. Held-to-maturity securities are placed on non-accrual status when the Company is in receipt of information indicating collection of interest is doubtful. Cash received on held-to-maturity securities placed on non-accrual status is recognized on a cash basis as interest income if and when received. The Company reviews its portfolio of held-to-maturity securities for impairment on a quarterly basis, recognizing an allowance, if any, by applying an estimated loss rate after consideration for the nature of collateral securing the financial asset as well as potential future changes in collateral values and historical loss information for financial assets secured with similar collateral. 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 in Accounting Standards Codification (“ASC”) Topic 321, Investments – Equity Securities (“ASC 321”), to the extent such investments are not subject to consolidation or the equity method. Under the measurement alternative, these financial instruments are carried at cost, less any impairment (assessed quarterly), plus or minus changes resulting from observable price changes in orderly transactions for an identical or similar investment of the same 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. Inve stments in debt instruments are accounted for at fair value, with changes in fair value reported in other income/(expenses).
Goodwill | Goodwill Goodwill is the excess 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, if one were to occur. Goodwill is considered impaired when the estimated fair value of the reporting unit that was allocated the goodwill is less than its carrying value. If the estimated fair value of such reporting unit is less than its carrying value, goodwill impairment is recognized based on that difference, not to exceed the carrying amount of goodwill. A reporting unit is an operating segment or a component of an operating segment provided that the component constitutes a business for which discrete financial information is available and management regularly reviews the operating results of that component. Goodwill is allocated to the Company’s U.S. business and European business components. 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. Goodwill is assessed for impairment annually on November 30 th . When performing its goodwill impairment test, the Company considers a qualitative assessment, when appropriate, and a quantitative assessment using the market approach and its market capitalization when determining the fair value of the reporting unit.
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. 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 .
Software Development Costs | Software Development Costs Software development costs incurred after the preliminary project stage is complete are capitalized if it is probable that the project will be completed and the software will be used as intended. Capitalized costs consist of employee compensation costs and fees paid to third parties who are directly involved in the application development efforts and are included in intangible assets, net in the Consolidated Balance Sheets. Such costs are amortized over the estimated useful life of the software on a straight-line basis and are included in depreciation and amortization in the Consolidated Statements of Operations. Once the application development stage is complete, additional costs are expensed as incurred.
Leases | Leases The Company accounts for its lease obligations in accordance with ASC Topic 842 , Leases (“ASC 842 ”), which requires the recognition of both (i) a lease liability equal to the present value of the remaining lease payments and (ii) an offsetting right-of-use asset. The remaining lease payments are discounted using the rate implicit in the lease, if known, or otherwise the Company’s incremental borrowing rate. After lease commencement, right-of-use assets are assessed for impairment and otherwise are amortized over the remaining lease term on a straight-line basis. These recognition requirements are not applied to short-term leases which are those with a lease term of 12 months or less. Instead, lease payments associated with short-term leases are recognized as an expense on a straight-line basis over the lease term. 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 components. The Company has elected to apply this practical expedient to all lease contracts, where applicable.
Deferred Consideration—Gold Payments | 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 observed on the CMX exchange, a selected discount rate and perpetual growth rate (Note 10). Changes in the fair value of this obligation are reported as gain/(loss) on revaluation of deferred consideration—gold payments in the Consolidated Statements of Operations.
Convertible Notes | Convertible Notes Convertible notes are carried at amortized cost, net of issuance costs. In accordance with Accounting Standards Update (“ASU”) 2020-06, Debt – Debt with Conversion and Other Options , the Company accounts for convertible instruments as a single liability (applicable to the convertible notes) or equity with no separate accounting for embedded conversion features unless the conversion feature meets the criteria for accounting under the substantial premium model or does not qualify for a derivative scope exception. Interest expense is recognized using the effective interest method and includes amortization of issuance costs over the life of the debt.
Contingencies | Contingencies The Company may be subject to reviews, inspections and investigations by regulatory authorities as well as legal proceedings arising in the ordinary course of business. The Company evaluates the likelihood of an unfavorable outcome of all legal or regulatory proceedings to which it is a party and accrues a loss contingency when the loss is probable and reasonably estimable.
Contingent Payments | Contingent Payments The Company recognizes a gain on contingent payments when the contingency is resolved and the gain is realized.
Earnings per Share | 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 convertible preferred stock (Note 13) and unvested share-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are participating securities and are included in the computation of EPS pursuant to the two-class method. Share-based payment awards that do not contain such rights are not deemed participating securities and are included in diluted shares outstanding (if dilutive). Diluted EPS is calculated under the treasury stock method and the two-class method. The calculation that results in the lowest diluted EPS amount for the common stock is reported in the Company’s consolidated financial statements. The treasury stock method includes the dilutive effect of potential common shares including unvested stock-based awards, the Series A non-voting convertible preferred stock and the convertible notes, if any. Potential common shares associated with the Series A non-voting convertible preferred stock and the convertible notes are computed under the if-converted method. Potential common shares associated with the conversion option embedded in the convertible notes are dilutive when the Company’s average stock price exceeds the conversion price.
Income Taxes | 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 that some portion or all the deferred tax assets will not be realized. Tax positions are evaluated utilizing a two-step process. The Company first determines whether any of its tax positions are more-likely-than-not to be sustained upon examination, based solely on the technical merits of the position. Once it is determined that a position meets this recognition threshold, the position is measured as the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settlement. The Company records interest expense and penalties related to tax expenses as income tax expense. The Global Intangible Low-Taxed Income (“GILTI”) provisions of the Tax Reform Act requires the Company to include in its U.S. income tax return foreign subsidiary earnings in excess of an allowable return on the foreign subsidiary’s tangible assets. An accounting policy election is available to either account for the tax effects of GILTI in the period that is subject to such taxes or to provide deferred taxes for book and tax basis differences that upon reversal may be subject to such taxes. The Company accounts for the tax effects of these provisions in the period that is subject to such tax. Non-income based taxes are recorded as part of other liabilities and other expenses.
Recently Adopted Accounted Pronouncements | Recently Adopted Accounting Pronouncements On January 1, 2021, the Company early adopted ASU 2020-06, Debt – Debt with Conversion and Other Options (ASU 2020-06) under the modified retrospective approach. Under the ASU, the accounting for convertible instruments was simplified by removing major separation models required under current GAAP. Accordingly, more convertible instruments are reported as a single liability or equity with no separate accounting for embedded conversion features. Certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception are removed and, as a result, more equity contracts will qualify for the scope exception. The ASU also simplifies the diluted earnings-per-share calculation in certain areas. Upon the adoption of this ASU, the Company reclassified the equity component related to the convertible notes, net of deferred taxes, reducing accumulated deficit by $616, increasing the carrying value of the convertible notes by $4,088, reducing additional paid-in capital by $3,682 and reducing deferred tax liabilities by $1,022. These updates also reduced interest expense recognized on the Company’s convertible notes by approximately $420 per quarter and $1,680 for the year ended December 31, 2021 (Note 12) and the impact on earnings per share was negligible. On January 1, 2021, the Company adopted ASU 2019-12, Income Taxes (Topic 740) – Simplifying the Accounting for Income Taxes (ASU 2019-12). The main objective of the standard is to reduce complexity in the accounting for income taxes by removing the f ollowing exceptions: (1) exception to the incremental approach for intraperiod tax allocation when there is a loss from continuing operations and income or a gain from other items (for example, discontinued operations or other comprehensive income); (2) exception to the requirement to recognize a deferred tax liability for equity method investments when a foreign subsidiary becomes an equity method investment; (3) exception to the ability not to recognize a deferred tax liability for a foreign subsidiary when a foreign equity method investment becomes a subsidiary; and (4) exception to the general methodology for calculating income taxes in an interim period when a year-to-date loss exceeds the anticipated loss for the year. The standard also simplifies the accounting for income taxes by enacting the following: (a) requiring that an entity recognize a franchise tax (or similar tax) that is partially based on income as an income-based tax and account for any incremental amount as a non-income-based tax; (b) requiring that an entity evaluate when a step up in the tax basis of goodwill should be considered part of the business combination in which the book goodwill was originally recognized and when it should be considered as a separate transaction; (c) specifying that an entity is not required to allocate the consolidated amount of current and deferred tax expense to a legal entity that is not subject to tax in its separate financial statements; and (d) requiring that an entity reflect the enacted change in tax laws or rates in the annual effective tax rate computation in the interim period that includes the enactment date. The Company has determined that the adoption of this standard did not have a material impact on its financial statements.
