Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes. Our provision for income taxes for the three months ended March 31, 2019 and 2018 was a tax expense of approximately $651,000 and $1.1 million, respectively, which resulted in an effective tax rate of 9.5% and 17.1%, respectively. The decrease in the income tax expense and effective income tax rate for the first quarter of 2019 as compared to the first quarter of 2018 was primarily due to an increase in the discrete tax benefit related to share-based payment awards.

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.
