Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company’s provision for income taxes includes U.S. federal, state, local and foreign taxes. The Company’s effective tax rate for the nine months ended September 30, 2020 and 2019 was approximately 20.8% and 15.6%, respectively. The effective tax rate for the nine months ended September 30, 2020 differed from the U.S. federal statutory rate of 21.0% primarily due to the effect of non-controlling interests and the tax impact of the exercise of equity compensation, partially offset by state, local and foreign taxes. The effective tax rate for the nine months ended September 30, 2019 differed from the U.S. federal statutory rate of 21.0% primarily due to the effect of non-controlling interests and other discrete items, partially offset by state and local taxes. The Company’s effective tax rate for the three months ended September 30, 2020 and 2019 was approximately 19.1% and 17.5%, respectively. The effective tax rate for the three months ended September 30, 2020 differed from the U.S. federal statutory rate of 21.0% primarily due to the effect of non-controlling interests and the tax impact of the exercise of equity compensation, partially offset by state, local and foreign taxes. The effective tax rate for the three months ended September 30, 2019 differed from the U.S. federal statutory rate of 21.0% primarily due to the effect of non-controlling interests, partially offset by state, local and foreign taxes and other discrete items. As a result of the Reorganization Transactions, the Corporation is subject to U.S. federal, state and local income taxes with respect to its taxable income, including its allocable share of any taxable income of TWM LLC, and is taxed at prevailing corporate tax rates. The Company’s actual effective tax rate will be impacted by the Corporation’s ownership share of TWM LLC, which will increase over time as the Continuing LLC Owners redeem or exchange their LLC Interests for shares of Class A common stock or Class B common stock, as applicable, or the Corporation purchases LLC Interests from the Continuing LLC Owners. The Company's consolidated effective tax rate will vary from period to period depending on redemptions, exchanges or purchases of LLC Interests as described above, changes in the geographic mix of its earnings and changes in tax legislation and tax rates. The Company expects to obtain an increase in its share of the tax basis of the assets of TWM LLC when LLC Interests are redeemed or exchanged by the Continuing LLC Owners and in connection with certain other qualifying transactions. This increase in tax basis may have the effect of reducing the amounts that the Corporation would otherwise pay in the future to various tax authorities. Pursuant to the Tax Receivable Agreement, the Corporation is required to make cash payments to the Continuing LLC Owners equal to 50% of the amount of U.S. federal, state and local income or franchise tax savings, if any, that the Corporation actually realizes (or in some circumstances are deemed to realize) as a result of certain future tax benefits to which we may become entitled. The Corporation expects to benefit from the remaining 50% of tax benefits, if any, that the Corporation may actually realize. See Note 7 – Tax Receivable Agreement. The tax benefit has been recognized in deferred tax assets on the September 30, 2020 consolidated statement of financial condition. As a result of the Refinitiv Contribution, the Company assumed the tax liabilities of the contributed entity. The contributed entity is under audit by the State of New Jersey for the tax years 2012 – 2015 and is appealing a tax assessment from an audit by the State of New Jersey for the tax years 2008 – 2011. At September 30, 2020, the tax liability related to the Refinitiv Contribution is $2.7 million and is included within accounts payable, accrued expenses and other liabilities on the consolidated statement of financial condition. The Company is indemnified by Refinitiv for tax liabilities that were assumed by the Company as a result of the Refinitiv Contribution. At September 30, 2020, $2.7 million is included in other assets on the consolidated statement of financial condition related to this indemnification.
