Note 5. Income Taxes	6 Months Ended
Jun. 30, 2020
Income Tax Disclosure [Abstract]
Income Taxes	We recognized income tax expense of $230,000 and $310,000 during the three and six-month periods ended June 30, 2020, respectively, compared to $33,000 and $46,000 during the same periods 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 and six-month period ended June 30, 2020, the variance between the Company’s effective tax rate and the U.S. statutory rate of 21% is primarily attributable to state income taxes. For the three and six-month periods ended June 30, 2019, the variance between the Company’s effective tax rate and the U.S. statutory rate is primarily attributable to the excess stock-based compensation tax benefit recognized in income tax expense during the periods, as well as foreign statutory tax rate differentials and tax credits.
