Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The effective tax rate for the three months ended December 31, 2017 and 2016 was 17.4% and 35.0%, respectively, and for the six months ended December 31, 2017 and 2016 was 22.0% and 33.1%, respectively. The decreases in the effective tax rates are primarily due to the Tax Cuts and Jobs Act (the “Act”) enacted on December 22, 2017 and the impact of sale of the CHSA and COBRA businesses in the three months ended December 31, 2016. The Act reduces the U.S. federal corporate income tax rate from 35% to 21%. In accordance with ASC 740 companies are required to re-measure deferred tax balances using the new enacted tax rates. The Act requires companies to pay a one-time transition tax on earnings of the Company's foreign subsidiaries that were previously tax deferred for U.S. income taxes and creates new taxes on the Company's foreign sourced earnings. The rate change is administratively effective at the beginning of the Company's fiscal year resulting in a blended rate for fiscal 2018 of 28.1%. Income tax expense reported for the three and six months ended December 31, 2017 was adjusted to reflect the effects of the Act and resulted in a decrease in income tax expense of approximately $98.0 million which includes a one-time net benefit of $45.7 million. The $45.7 million is comprised of the application of the newly enacted rates to the Company's U.S. deferred tax balances partially offset by the one-time transition tax and the recording of a valuation allowance against the Company's foreign tax credits which may not be realized. The Act’s foreign tax credit provisions may limit the Company’s ability to utilize existing foreign tax credits in future periods, accordingly we have estimated that approximately $23.1 million will expire unutilized. The accounting for the effects of the rate change on deferred tax balances is not complete and provisional amounts were recorded for these items. The Company re-measured certain deferred tax assets and liabilities based on the rates at which they are expected to reverse in the future. The benefit recorded relating to the re-measurement of the Company's deferred tax balances was $84.7 million. The Company is still analyzing certain aspects of the Act and refining calculations, which could potentially affect the re-measurement of these balances or potentially give rise to new deferred tax amounts. The one-time transition tax is based on the total post-1986 earnings and profits ("E&P") that was previously deferred from US income taxes. The Company recorded a provisional amount for the one-time transition tax liability of $15.9 million for the Company's foreign subsidiaries. The Company has not yet completed the calculation of the total post-1986 E&P for these foreign subsidiaries. Further, the transition tax is based in part on the amount of those earnings held in cash and other specified assets. This amount may change when the Company finalizes the calculation of post-1986 foreign E&P previously deferred from US federal taxation and finalizes the amounts held in cash or other specified assets.
