Income Tax Disclosure [Abstract]
Income Taxes	11. Income Taxes Our income tax provision represents federal, state, and international taxes on our income recognized for financial statement purposes and includes the effects of temporary differences between financial statement income and income recognized for tax return purposes. Deferred tax assets and liabilities are recorded for temporary differences between the financial reporting basis and the tax basis of assets and liabilities as adjusted for the expected benefits of utilizing net operating loss carryforwards. We record a valuation allowance to reduce our deferred tax assets to reflect the net deferred tax assets that we believe will be realized. In assessing the likelihood that we will be able to recover our deferred tax assets and the need for a valuation allowance, we consider all available evidence, both positive and negative, including historical levels of pre-tax book income, expiration of net operating losses, expectations and risks associated with estimates of future taxable income, and ongoing prudent and feasible tax planning strategies, as well as current tax laws. As of March 31, 2020, we continue to record a valuation allowance of $12.0 million against deferred tax assets attributable to state net operating loss carryovers. We recorded an income tax expense of $8.2 million during the three months ended March 31, 2020, consisting primarily of $3.6 million from US and foreign operations, $2.1 million of state taxes in the U.S., $1.3 million attributable to stock-based compensation, and $1.2 million of base erosion anti-abuse tax (“BEAT”) in the U.S. The total amount of unrecognized tax benefits as of March 31, 2020, and December 31, 2019, were $1.6 million, including $0.2 million of accrued interest, and $1.5 million, including $0.2 million of accrued interest, respectively. Of the total amount of unrecognized tax benefits as of March 31, 2020, $1.6 million represents the amount that, if recognized, would favorably impact our effective income tax rate. It is reasonable to expect that the amount of unrecognized tax benefits will change in the next twelve months; however, we do not expect the change to have a significant impact on our results of operations or financial condition. We file income tax returns in the U.S. federal jurisdiction, various states, and foreign jurisdictions. With a few exceptions, we are no longer subject to U.S. federal, state and local, or non-U.S. income tax examinations by tax authorities for years before 2015.
