Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company’s practice is to recognize interest and/or penalties related to income tax matters in income tax expense. The Company had no accruals for interest and penalties on the Company’s Condensed Consolidated Balance Sheets at March 31, 2018 or September 30, 2017, and has not recognized any interest or penalties in the Condensed Consolidated Statements of Operations for the three and six months ended March 31, 2018 or 2017, respectively. On December 22, 2017, the Tax Cuts and Jobs Act (“TCJA”) was enacted into law, which significantly changes existing U.S. tax law and includes provisions that affect our business. The TCJA reduces the U.S. federal statutory tax rate from 35% to 21% effective January 1, 2018. The TCJA is effective in the second quarter of fiscal year 2018 and the effective tax rate for the quarter ended December 31, 2017 is a blended rate reflecting the anticipated benefit of the three quarters of federal tax rate reductions for fiscal 2018. During the three and six months ended March 31, 2018, we recorded an income tax benefit of zero and $1.3 million, respectively, resulting from the application of TCJA to existing deferred tax balances based on reasonable estimates for those tax effects. The deemed repatriation of undistributed foreign earnings is not expected to result in a material change to our financial results. Our accounting for the tax effects of the TCJA will be completed during the measurement period, which should not extend beyond one year from the enactment date. The final impact of the TCJA may differ due to and among other things, changes in interpretations, assumptions made by the Company, the issuance of additional guidance, and actions the Company may take as a result.
