Income Taxes	11. Income Taxes Subsequent to consummation of the Reorganization Transactions and the IPO, the Company is subject to U.S. federal, state and local income tax at the rate applicable to corporations less the rate attributable to the noncontrolling interest in Virtu Financial. These noncontrolling interests are subject to U.S. taxation as partnerships. Accordingly, for the three months ended March 31, 2017 and 2016, the income attributable to these noncontrolling interests is reported in the condensed consolidated statements of comprehensive income, but the related U.S. income tax expense attributable to these noncontrolling interests is not reported by the Company as it is the obligation of the individual partners. The Company’s provisions for income taxes were $2.8 million and $7.3 million for the three months ended March 31, 2017 and 2016, respectively; and the effective tax rates were 11.8% and 12.5% for the three months ended March 31, 2017 and 2016, repectively. Income tax expense is also affected by the differing effective tax rates in foreign, state and local jurisdictions where certain of the Company’s subsidiaries are subject to corporate taxation. Deferred income taxes arise primarily due to the amortization of the deferred tax assets recognized in connection with the IPO (see Note 4 and Note 13), differences in the valuation of financial assets and liabilities, and in connection with other temporary differences arising from the deductibility of compensation and depreciation expenses in different time periods for book and income tax return purposes. There are no expiration dates on the deferred tax assets. The provisions of ASC 740 require that carrying amounts of deferred tax assets be reduced by a valuation allowance if, based on the available evidence, it is more likely than not that some portion or all of the deferred tax assets will not be realized. Accordingly, the need to establish valuation allowances for deferred tax assets is assessed periodically with appropriate consideration given to all positive and negative evidence related to the realization of the deferred tax assets. A valuation allowance against deferred tax assets at the balance sheet date is not considered necessary because it is more likely than not that the deferred tax asset will be fully realized. There are no unrecognized tax benefits as of March 31, 2017 and December 31, 2016. The Company is subject to taxation in U.S. federal, state, local and foreign jurisdictions. As of March 31, 2017, the Company’s tax years for 2013 through 2016 and 2010 through 2016 are subject to examination by U.S. and non-U.S. tax authorities, respectively.
