Income Tax Disclosure [Abstract]  
Income Tax Disclosure [Text Block] Income Taxes
Our income tax expense was $9,381 and $6,794 for the three months ended September 30, 2021 and 2020, respectively. Excluding the effect of discrete tax adjustments, our estimated annual effective tax rate is higher for fiscal 2022 as compared to fiscal 2021 primarily due to a less favorable mix of earnings. Our effective tax rate continues to be negatively impacted by losses in certain jurisdictions where we are unable to recognize a tax benefit in the current period.

As of September 30, 2021 we had unrecognized tax benefits of $15,400, including accrued interest and penalties of $1,049. We recognize interest and, if applicable, penalties related to unrecognized tax benefits in the provision for income taxes. If recognized, $1,169 of unrecognized tax benefits would reduce our tax expense. It is reasonably possible that a reduction in unrecognized tax benefits may occur within the next twelve months in the range of $300 to $350 related to the lapse of applicable statutes of limitations. We believe we have appropriately provided for all tax uncertainties.
    
We conduct business in a number of tax jurisdictions and, as such, are required to file income tax returns in multiple jurisdictions globally. The years 2014 through 2021 remain open for examination by the IRS and the years 2015 through 2021 remain open for examination in the various states and non-US tax jurisdictions in which we file tax returns. We believe that our income tax reserves are adequately maintained taking into consideration both the technical merits of our tax return positions and ongoing developments in our income tax audits. However, the final determination of our tax return positions, if audited, is uncertain, and there is a possibility that final resolution of these matters could have a material impact on our results of operations or cash flows.
