Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Our effective tax rate was 0.1% and 51.7% for the three months ended March 31, 2020 and 2019, respectively. Taxes in both periods relate to Louisiana state income tax and Texas margin tax. In the first quarter of 2020, the rate is largely driven by the recording of a valuation allowance against the Louisiana deferred tax assets, caused by the asset impairment recorded. In the first quarter of 2019, our effective tax rate was significantly higher based on our then full year forecast of net income before taxes and the application of our estimated annual rate to our year-to-date results. We finished 2019 with an annual effective rate of 0.2%.
