Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company recorded income tax expenses of $0.6 million and $0.5 million in the three and nine months ended December 31, 2017, respectively. The Company recorded income tax benefit of $0.1 million and expense of $1.0 million in the three and nine months ended December 31, 2016, respectively. As a result of purchase accounting for the acquired intangible assets in the ITC acquisition, the Company recorded a deferred tax liability of $1.1 million for the difference in book and tax basis. As a result, the Company was able to benefit additional deferred tax assets and therefore released a corresponding valuation allowance of $1.1 million during the nine months ended December 31, 2017. Goodwill recognized in the acquisition is not deductible for tax purposes. Section 382 of the U.S. Internal Revenue Code of 1986, as amended (the “IRC”), provides limits on the extent to which a corporation that has undergone an ownership change (as defined in the IRC) can utilize any net operating loss ("NOL") and general business tax credit carryforwards it may have. The Company conducted a study as a result of the Company's May 2017 equity offering to determine whether Section 382 could limit the use of its carryforwards in this manner. After completing this study, the Company has concluded that the limitation will not have a material impact on its ability to utilize its NOL carryforwards. If there were material ownership changes subsequent to the study, such changes could limit the Company's ability to utilize its NOL carryforwards. The Company increased its NOL’s by $0.3 million due to acquired losses in the nine months ended December 31, 2017 from ITC. The Company conducted a study on the acquired NOL and concluded that the limitations under Section 382 will not have a material impact on its ability to utilize its NOL carryforwards. On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (“tax reform”) 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. The tax reform was enacted as of December 22, 2017. 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 reduction to its net U.S. deferred tax asset was offset by a corresponding reduction to its valuation allowance. In addition, the new legislation includes a transition tax in which all foreign earnings are deemed to be repatriated to the U.S. and taxable at specified rates included within the tax reform. The Company is in the process of calculating the impact of the transition tax. The analysis is complex and encompasses many years. The Company is working with its foreign subsidiaries and their local tax service providers to gather historical information, including historical tax returns, in order to complete the calculation. Pursuant to Staff Accounting Bulletin No. 118, the Company's measurement period for the tax impact of the tax law changes is still open. At this time, the Company does not anticipate a material impact due to the transition tax, and the Company anticipates completing the analysis under ASC Topic 740 by March 31, 2018, at which time the Company expects to be in a position to book any required adjustments for any transition tax impact. The Company does not anticipate any other material tax exposure due to the tax reform at this time. 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, 2017 and did not have any gross unrecognized tax benefits as of March 31, 2017.
