|3 Months Ended|
Mar. 31, 2017
We file income tax returns in the United States federal jurisdiction, as well as in various state jurisdictions. We did not record any current or deferred U.S. federal income tax provision or benefit during the three months ended March 31, 2017 and 2016 because we have experienced operating losses since inception. We have recognized a full valuation allowance related to our net deferred tax assets, including substantial net operating loss carryforwards. As of March 31, 2017, we had approximately $61.0 million of net operating loss carryforwards and amortizable expenses related to acquisitions that can be used to offset our income for federal and state tax purposes.
The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.
