Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes For the three months ended September 30, 2018, the Company recognized income tax expense of approximately $0.6 million. For the three months ended September 30, 2017, the Company recognized income tax expense of approximately $1.3 million, which included a discrete tax benefit of $0.4 million related principally to an intercompany asset transfer.

The changes in the effective tax rate and tax expense between the periods resulted primarily from changes in the mix of earnings in various geographic jurisdictions between the current year and the same period of last year somewhat offset by the reduction in the U.S. corporate tax rate following the enactment of the 2017 U.S. Tax Cut and Jobs Act.

If the Company's estimate of income tax liabilities proves to be less than the ultimate assessment, then a further charge to expense would be required.

A final decision has yet to be issued by the Tax Court due to other outstanding issues related to the case. At this time, the U.S. Department of the Treasury has not withdrawn the requirement to include share-based compensation from its regulations.
