Income Tax Disclosure [Text Block]	Note 5 - Income taxes The determination of the consolidated provision for income taxes, deferred tax assets and liabilities and related valuation allowances requires management to make judgments and estimates. As a company with subsidiaries in foreign jurisdictions, the process of calculating income taxes involves estimating current tax obligations and exposures in each jurisdiction as well as making judgments regarding the future recoverability of deferred tax assets. Income earned in the United Arab Emirates is not subject to local country income tax. Additionally, the relative proportion of taxable income earned domestically versus internationally can fluctuate significantly from period to period. Changes in the estimated level of annual pre-tax income, tax laws and the results of tax audits can affect the overall effective income tax rate, which impacts the level of income tax expense and net income. Judgments and estimates related to the Company's projections and assumptions are inherently uncertain; therefore, actual results could differ materially from projections. The Company's effective tax rate ("ETR") from operations for the second quarter and year-to-date in fiscal 2020 was ( 56.8% ) and 12.3% compared to ( 7.6% ) and 2.1% during the respective prior year periods. The change in the ETR from the prior year quarter to the current year quarter was largely due to changes in the mix of income and loss in various jurisdictions. The amount of unrecognized tax benefits, including interest and penalties at July 31, 2020, recorded in other long-term liabilities was $0.1 million, all of which would impact the Company's ETR if recognized. On March 7, 2020, President Trump signed into law the Coronavirus Aid, Relief and Economic Security Act (H.R. 748 ) (the "CARES Act"). Among the changes to the U.S. federal income tax rules, the CARES Act restored net operating loss carryback rules that were eliminated by the U.S. Tax Cuts and Jobs Act ("Tax Act"), restored 100% bonus depreciation for qualified improvement property, modified the limit on the deduction for net interest expense and accelerated the timeframe for refunds of alternative minimum tax credits. With consideration to these changes to federal income tax rules, there is no net impact to the Company's deferred taxes due to the full valuation allowance. The Company will continue to evaluate the effects of the CARES Act as additional legislative guidance becomes available.
