Schedule of Components of Income Tax Expense (Benefit) [Table Text Block]	Income Taxes The provision for income taxes for the three months ended April 30, 2018 was an expense of $218 on income before income taxes of $4,243 for a consolidated effective tax rate of 5.1%. The provision for income taxes for the six months ended April 30, 2018 was a benefit of $2,840 on income before income taxes of $6,043 for a consolidated effective tax rate of (47.0)%. The consolidated effective tax rate for the year decreased primarily due to the enactment of the TCJA on December 22, 2017. On December 22, 2017, the TCJA was enacted into law, which changed various U.S. corporate income tax provisions within the existing Internal Revenue Code. The TCJA, among other things, lowered the U.S. corporate tax rate from 35% to 21% effective January 1, 2018, while also repealing the deduction for domestic production activities, implementing a modified territorial tax system and imposing a repatriation tax on deemed repatriated earnings of foreign subsidiaries. As a result, we are provisionally estimating our one-time non-cash net tax benefit related to the remeasurement of our U.S. deferred taxes to be approximately$3,126 and $840 for the three months ended January 31, 2018 and for the three months ended April 30, 2018, respectively. We have performed an analysis on taxes related to deemed repatriation of foreign earnings and concluded we have no liability based on information to date. We will continue to analyze the TCJA to assess the full effects on our financial results, including disclosures, for our fiscal year ending October 31, 2018. In accordance with guidance provided by Staff Accounting Bulletin No. 118 (SAB 118), we have not completed our accounting for the tax effects of the TCJA; however, in certain cases, as described above, we have made a provisional estimate of the effects on our existing deferred tax balances and the one-time transition tax. Any adjustments to the provisional amounts will be recognized as a component of the provision for income taxes in the period in which such adjustments are determined, but in any event, no later than the fourth quarter of 2018, in accordance with SAB 118. The provision for income taxes for the three months ended April 30, 2017 was an expense of $2,323 on income before income taxes of $6,552 for a consolidated effective tax rate of 35.5%. The consolidated effective tax rate was impacted by foreign losses without a tax benefit. The provision for income taxes for the six months ended April 30, 2017 was an expense of $2,247 on income before income taxes of $4,458 for a consolidated effective tax rate of 50.4%. The consolidated effective tax rate was impacted by foreign losses without a tax benefit.
