Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company recorded an income tax expense of $1.6 million and $4.5 million in the three and nine months ended December 31, 2018, respectively. The Company recorded income tax expense of $0.6 million and $0.5 million in the three and nine months ended December 31, 2017, respectively. On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (the “Act”) was signed into law. ASC Topic 740 requires deferred tax assets and liabilities to be measured using the enacted rate for the period in which they are expected to reverse. Accordingly, the new 21% U.S. Federal corporate tax rate was used to measure the U.S. deferred tax assets and liabilities that will reverse in future periods. The Company's deferred tax attributes are generally subject to a full valuation allowance in the U.S. and thus, this adjustment to the attributes did not impact the tax provision. In addition, the new legislation includes a one-time transition tax in which all foreign earnings are deemed to be repatriated to the U.S. and taxable at specified rates included within the Act. The Company reviewed the accumulated foreign earnings aggregated across all non U.S. subsidiaries, net of foreign deficits. The Company believes it is in an aggregate net foreign deficit position for U.S. tax purposes and therefore not liable for the transition tax. The SEC staff issued Staff Accounting Bulletin No. 118, which provides guidance for companies that have not completed their accounting for the income tax effects of the Act in the period of enactment, allowing for a measurement period of up to one year after the enactment date to finalize the recording of the related tax impacts. As of December 31, 2018, the Company completed its tax accounting for the income tax effects of the Act and made no updates to its initial estimates. The Act had no significant financial impact for the fiscal year ended March 31, 2018. Accounting for income taxes requires a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if, based on the technical merits, it is more likely than not the position will be sustained upon audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely to be realized upon ultimate settlement. The Company re-evaluates these uncertain tax positions on a quarterly basis. The evaluation is based on factors including, but not limited to, changes in facts or circumstances, changes in tax law, effectively settled issues under audit and new audit activity. Any changes in these factors could result in the recognition of a tax benefit or an additional charge to the tax provision. The Company did not identify any uncertain tax positions in the nine months ended December 31, 2018 and did not have any gross unrecognized tax benefits as of March 31, 2018.
