Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company is not subject to taxation under the laws of Bermuda since it was organized as a Bermuda Exempted Limited Company, for which there is no current tax regime. The Company’s provision for income taxes is primarily based on income taxes in the United States for federal, state and local taxes. The Company’s effective income tax rate for the three months ended December 31, 2017 and 2016 was 0.51% and (0.36)%, respectively. The Company’s effective income tax rate for the nine months ended December 31, 2017 and 2016 was (0.64)% and (0.06)%, respectively. The Company's effective income tax rate for all periods presented differs from the Bermuda federal statutory rate of 0% primarily due to the U.S. permanent unfavorable tax differences, and a valuation allowance that effectively eliminates the Company's net deferred tax assets in the United States. On December 22, 2017, the President of the United States signed into law an Act to provide for reconciliation pursuant to titles II and V of the concurrent resolution on the budget for fiscal year 2018 (commonly known as “the Tax Cuts and Jobs Act”), which introduced a comprehensive set of tax reforms. The Tax Cuts and Jobs Act significantly revises U.S. tax law by, among other provisions, lowering the U.S. federal statutory income tax rate from 35% to 21% and eliminating or reducing certain income tax deductions. The effects of changes in tax laws are required to be recognized in the period in which the legislation is enacted. However, due to the complexity and significance of the Tax Cuts and Jobs Act’s provisions, the SEC staff issued Staff Accounting Bulletin No. 118 (“SAB 118”), which allows companies to record the tax effects of the Tax Cuts and Jobs Act on a provisional basis based on a reasonable estimate, and then, if necessary, subsequently adjust such amounts during a limited measurement period as more information becomes available. The measurement period ends when a company has obtained, prepared, and analyzed the information necessary to finalize its accounting, but cannot extend beyond one year from enactment. The Tax Cuts and Jobs Act did not have a material impact on the Company’s financial statements since its deferred temporary tax differences are fully offset by a valuation allowance and the Company does not have any off shore earnings from which to record the mandatory transition tax. However, given the significant complexity of the Tax Cuts and Jobs Act, anticipated guidance from the U.S. Treasury about implementing the Tax Cuts and Jobs Act, and the potential for additional guidance from the SEC or the FASB related to the Tax Cuts and Jobs Act, these estimates may be adjusted during the measurement period. The provisional amounts were based on the Company’s present interpretations of the Tax Cuts and Jobs Act and currently available information, including assumptions and expectations about future events, such as its projected financial performance, and are subject to further refinement as additional information becomes available (including the Company’s actual results of operations for the year ending March 31, 2018, as well as potential new or interpretative guidance issued by the FASB or the Internal Revenue Service and other tax agencies) and further analyses are completed. The Company continues to analyze the changes in certain income tax deductions, and gather additional data to compute the full impacts on the Company’s deferred and current tax assets and liabilities. The Company assesses the realizability of its deferred tax assets at each balance sheet date based on available positive and negative evidence to determine the amount which is more likely than not to be realized and records a valuation allowance as necessary.
