Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes In the quarter ended December 31, 2015, the Company determined that a small change in its estimated pretax results for the year ended March 31, 2016 would create a large change in its expected annual effective rate. Accordingly, it was determined that a reliable estimate of the expected annual effective tax rate could not be made. As a result, the Company computed its tax provision (benefit) using the cut-off method which resulted in an income tax benefit of $45.1 million for the three months ended December 31, 2015 based on the actual taxes attributable to its year-to-date earnings. This tax benefit is primarily related to the mix of the Company's pre-tax income (loss) generated across the various jurisdictions in which the Company operates in addition to the tax deductions generated by the Company's capital structure. The income tax provision for the three and nine months ended December 31, 2014 was calculated by estimating the Company's annual effective tax rate, and then applying the effective tax rate to income before income taxes for the period, along with any items that relate discretely to the period. The Company's effective tax rate differs from the federal statutory rate and has changed from the prior period and could fluctuate significantly in the future, as the Company's effective tax rates are affected by many factors, including the overall level of pre-tax income, the mix of pre-tax income generated across the various jurisdictions in which the Company operates, changes in tax laws and regulations in those jurisdictions, changes in valuation allowances on its deferred tax assets, tax planning strategies available to the Company, and other discrete items.
