Income Tax Disclosure [Abstract]
Income Taxes	7.            Income Taxes The income tax benefit was $326 thousand for the three months ended June 30, 2019 compared to an income tax expense of $249 thousand in the same period of 2018. The income tax benefit for the nine months ended June 30, 2019 was $466 thousand and tax expense for the same period of the prior year was $1.2 million primarily due to the enactment of the Tax Cuts and Jobs Act. The U.K. did not have any income tax expense in the three or nine-month periods of fiscal year 2019 due to benefits from the pension contribution and utilization of a small portion of its net tax operating loss. The provisions above are estimates, and accordingly, changes to these estimates will be recorded in subsequent periods as more information and guidance becomes available.
