Income Tax Disclosure [Abstract]
Income Taxes	6. Income Taxes Our effective tax rate for the three months ended March 31, 2020 was 11.2%, based on an estimated annual effective tax rate of 8.3% and including the impact of certain return to provision adjustments in the quarter. Income taxes estimated for the year include state and foreign income taxes in jurisdictions where we have no net operating losses. As of March 31, 2020 we continue to maintain a full valuation allowance against our net deferred tax assets based on our assessment that it is not more likely than not these future benefits will be realized before expiration. A future release of the valuation allowance will result in a material tax benefit recognized in the quarter of release.
