Income Tax Disclosure [Text Block]	12. Income Taxes The Company recorded an income tax benefit of $ 1.5 million and $ 1.2 million in the three and nine month periods ended December 31, 2020 , respectively. The Company recorded income tax expense of $0.1 million in the three months ended December 31, 2019 , and less than $0.1 million in the nine months ended December 31, 2019 . As a result of a difference in book and tax basis related to the intangible assets acquired in the Acquisition (see Note 2, "NEPSI Acquisition"), the Company recorded a deferred tax liability of $1.7 million. As a result, the Company was able to benefit from additional deferred tax assets and therefore released a corresponding valuation allowance of $1.7 million during the three and nine months ended December 31, 2020 . The purchase price allocation is preliminary and has not been finalized as the analysis on the assets and liabilities acquired, primarily the tax related liability, may require further adjustments to the Company's purchase accounting that could result in measurement period adjustments that would impact the Company's reported net assets and goodwill as of October 1, 2020. Material changes, if any, to the preliminary allocation summarized in Note 2, "NEPSI Acquisition" will be reported once the related uncertainties are resolved, but no later than October 1, 2021. Goodwill recognized in the Acquisition is not deductible for tax purposes. 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, 2020 and did not have any gross unrecognized tax benefits as of March 31, 2020 .
