Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	Basis of Presentation The accompanying condensed consolidated balance sheet as of March 31, 2017, has been derived from audited consolidated financial statements. The accompanying unaudited interim condensed consolidated financial statements have been prepared on the same basis as our annual audited consolidated financial statements and in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial statements. In the opinion of management, such unaudited information includes all adjustments (consisting only of normal recurring accruals) necessary for a fair presentation of this interim information. Operating results and cash flows for interim periods are not necessarily indicative of results that can be expected for the entire year. The information included in this report should be read in conjunction with our audited consolidated financial statements and notes thereto included in our Annual Report on Form 10 -K for the year ended March 31, 2017. The summary of our significant accounting policies is incorporated by reference to our Annual Report on Form 10 -K for the year ended March 31, 2017.
New Accounting Pronouncements, Policy [Policy Text Block]	Recently Issued Accounting Pronouncements In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2014 - 09, Revenue from Contracts with Customers (Topic 606 ) , which will replace most existing revenue recognition guidance in U.S. GAAP and is intended to improve and converge with international standards the financial reporting requirements for revenue from contracts with customers. The core principle of ASU 2014 - 09 is that an entity should recognize revenue for the transfer of goods or services equal to the amount that it expects to be entitled to receive for those goods or services. ASU 2014 - 09 also requires additional disclosures about the nature, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments. ASU 2014 - 09 allows for adoption either on a full retrospective basis to each prior reporting period presented or on a modified retrospective basis with the cumulative effect of initially applying the new guidance recognized at the date of initial application, which will be effective for the Company beginning April 1, 2018. We plan to adopt ASU 2014 - 09 and its amendments on a modified retrospective basis and are continuing to assess all future impacts of the guidance by reviewing our current contracts with customers to identify potential differences that could result from applying the new guidance. Based on our preliminary review, we expect that the adoption of ASU 2014 - 09 will not have a material impact on our consolidated financial statements. As we complete our overall assessment, we are evaluating our accounting policies and practices, business processes, systems and controls to determine if changes are necessary to support the new revenue recognition and disclosure requirements. Our assessment will be completed during the year ending March 31, 2018. In January 2017, the FASB issued ASU 2017 - 04, Intangibles – Goodwill and Other , which eliminates the requirement to calculate the implied fair value of goodwill to measure a goodwill impairment charge. ASU 2017 - 04 is required to be applied prospectively and we elected to early adopt ASU 2017 - 04 effective April 1, 2017. We do not anticipate that the adoption will have a significant impact on our consolidated financial statements.
