Income Tax Disclosure [Text Block]	Note 1 0 – Income tax es On March 27, 2020, the United States enacted the Coronavirus Aid, Relief and Economic Security Act (the "CARES Act"). The CARES Act is an emergency economic stimulus package that includes spending and tax breaks to strengthen the United States economy and fund a nationwide effort to curtail the effects of the COVID- 19 pandemic. The CARES Act includes several provisions that provide economic relief for individuals and businesses. We continue to evaluate the impact the CARES Act will have on our tax obligations, but have concluded it did not materially impact our income taxes for the three and nine months ended July 31, 2020. We use an estimated annual effective tax rate, which is based on expected annual income, statutory tax rates and tax planning opportunities available in the various jurisdictions in which we operate, to determine its quarterly provision (benefit) for income taxes. Certain significant or unusual items are separately recognized in the quarter in which they occur and can be a source of variability in the effective tax rates from quarter to quarter. The provision or benefit for income taxes was 63% and 21% of (loss) income before income taxes for the three months ended July 31, 2020 ( the “fiscal 2020 quarter”) and 2019 (the “fiscal 2019 quarter”), respectively, and 38% and 22% of (loss) income before income taxes for the nine months ended July 31, 2020 ( the “fiscal 2020 period”) and 2019 (the “fiscal 2019 period”), respectively. The change in the effective tax rate from the fiscal 2019 period to fiscal 2020 period was primarily driven by the disproportionate impact of various permanent book-tax differences with respect to our forecasted book income or loss in each period. We had $101,000 and $80,000 of unrecognized tax benefits, inclusive of interest and penalties, as of July 31, 2020 and October 31, 2019, respectively. The unrecognized tax benefits, if recognized, would result in a net tax benefit of $26,000 as of July 31, 2020.
