Income Tax Disclosure [Text Block] | Note 8. Income Taxes The Company generally calculates its effective income tax rate at the end of an interim period using an estimate of the annualized effective income tax rate expected to be applicable for the full fiscal year. However, when a reliable estimate of the annualized effective income tax rate cannot be made, the Company computes its provision for income taxes using the actual effective income tax rate for the results of operations reported within the year-to-date periods. The Company’s effective income tax rate is highly influenced by relative income or losses reported and the amount of the nondeductible stock-based compensation associated with grants of its common stock options and from the results of international operations. A small change in estimated annual pretax income can produce a significant variance in the annualized effective income tax rate given the expected amount of these items. As a result, the Company has computed its provision for income taxes for the three-month periods ended March 31, 2025 and 2024 by applying the actual effective tax rates to income or reported within the condensed consolidated financial statements through those periods. The provision for income taxes for the three-month period ended March 31, 2024 included a non-recurring adjustment for unrecognized tax benefits related to foreign taxes of $100,000 which offset income tax expense for the same period.
