Income Tax Disclosure [Text Block] | H. Income Taxes The effective tax rate for the three months ended September 30, 2018 was 20.6%. The rate differs slightly from the U.S. federal statutory rate of 21% primarily due to the favorable impact of foreign earnings of NAIE, which are taxed at less than the U.S. statutory rate. The effective tax rate for the three months ended September 30, 2017 was 28.0%. To determine our quarterly provision for income taxes, 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 to which we are subject. 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 rate from quarter to quarter. There were no significant discrete items for the three months ended September 30, 2018. We recognize interest and penalties related to uncertain tax positions, if any, as an income tax expense. We record valuation allowances to reduce our deferred tax assets to an amount we believe is more likely than not to be realized. In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. During the three months ended September 30, 2018, there was no change to our valuation allowance for our deferred tax assets. Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are measured using enacted tax rates, for each of the jurisdictions in which we operate, expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized as income or expense in the period that includes the enactment date for such new rates. We are subject to taxation in the U.S., Switzerland and various state jurisdictions. Our tax years for the fiscal year ended June 30, 2015 and forward are subject to examination by the U.S. tax authorities and our years for the fiscal year ended June 30, 2007 and forward are subject to examination by the state tax authorities. Our tax years for the fiscal year ended June 30, 2015 and forward are subject to examination by the Swiss tax authorities. It is our policy to establish reserves based on management’s assessment of exposure for certain positions taken in previously filed tax returns that may become payable upon audit by tax authorities. Our tax reserves are analyzed quarterly and adjustments are made as events occur that we believe warrant adjustments to those reserves. There were no adjustments to reserves in the three months ended September 30, 2018.
