Note 5. Income Taxes	3 Months Ended
Mar. 31, 2020
Income Tax Disclosure [Abstract]
Income Taxes	We recognized income tax expense of $80,000 for the three-month period ended March 31, 2020, compared to income tax expense of $13,000 during the same period of 2019. At the end of each interim period, we estimate the effective tax rate we expect to be applicable for the full fiscal year and this rate is applied to our results for the year-to-date period, and then adjusted for any discrete period items. For the three-month period ended March 31, 2020, the variance between the Company’s effective tax rate and the U.S. statutory rate of 21% is primarily attributable to state income tax. For the three-month periods ended March 31, 2019, the variance between our effective tax rate and the U.S. statutory rate, is primarily attributable to excess stock-based compensation tax benefits of $35,000, recognized in income tax expense during the period, as well as, tax credits offset by state income taxes.
