Income Tax Disclosure [Abstract] |
Income Taxes | Income Taxes The Company is incorporated in Switzerland but operates in various countries with differing tax laws and rates. Further, a portion of the Company’s income before taxes and the provision for (benefit from) income taxes are generated outside of Switzerland. The Company has not adjusted the net provisional charge from remeasuring deferred tax assets related to the Tax Cuts and Jobs Act (the "Tax Act") in the United States in fiscal year 2018. The Company will continue to refine the estimate based on ongoing analysis and available information and interpretations through the third quarter of fiscal year 2019. The income tax benefit for the three months ended June 30, 2018 was $5.2 million based on an effective income tax rate of (15.7)% of pre-tax income, compared to an income tax benefit of $5.4 million based on an effective income tax rate of (17.2)% of pre-tax income for the three months ended June 30, 2017. The change in the effective income tax rate for the three months ended June 30, 2018, compared to the three months ended June 30, 2017, is primarily due to the mix of income and losses in the various tax jurisdictions which the Company operates and less excess tax benefits recognized in the United States in the three months ended June 30, 2018. The Company recognized excess tax benefits of $8.3 million at 21% federal corporate income tax rate post the Tax Act in the three months ended June 30, 2018. In the same period in fiscal year 2018, the Company recognized $9.9 million of excess tax benefits at 35% federal corporate income tax rate, offset by valuation allowance of $1.3 million for federal tax credit carryforwards after adoption of ASU 2016-09. In the three months ended June 30, 2018 and June 30, 2017, there was a discrete tax benefit of $0.9 million and $0.7 million, respectively, from the reversal of uncertain tax positions from the expiration of statutes of limitations. As of June 30, 2018 and March 31, 2018, the total amount of unrecognized tax benefits due to uncertain tax positions was $68.5 million and $69.1 million, respectively, all of which would affect the effective income tax rate if recognized. As of June 30, 2018 and March 31, 2018, the Company had $33.8 million and $35.0 million, respectively, in non-current income taxes payable including interest and penalties, related to the Company's income tax liability for uncertain tax positions. The Company recognizes interest and penalties related to unrecognized tax positions in income tax expense. As of June 30, 2018 and March 31, 2018, the Company had $2.4 million and $2.3 million, respectively, of accrued interest and penalties related to uncertain tax positions. Although the Company has adequately provided for uncertain tax positions, the provisions on these positions may change as revised estimates are made or the underlying matters are settled or otherwise resolved. During fiscal year 2019, the Company continues to review its tax positions and provide for or reverse unrecognized tax benefits as issues arise. During the next twelve months, it is reasonably possible that the amount of unrecognized tax benefits could increase or decrease significantly due to changes in tax law in various jurisdictions, new tax audits and changes in the U.S. dollar as compared to other currencies. Excluding these factors, uncertain tax positions may decrease by as much as $3.3 million from the lapse of the statutes of limitations in various jurisdictions during the next twelve months.
