Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES In determining its interim provision for/(benefit from) income taxes, the Company uses an estimated annual effective tax rate, which is based on expected annual profit before tax, statutory tax rates and tax planning opportunities available in the various jurisdictions in which the Company operates. Certain significant or unusual items are separately recognized in the quarter in which they occur and can be a source of variability in the effective tax rates from quarter to quarter. The Company’s worldwide effective tax rates for the three months ended March 31, 2019 and 2018 were 5.4% and (34.5)%, respectively. The Company’s effective tax rates benefited from excess tax benefits recorded upon vesting or exercise of stock-based awards of $11,513 and $4,690 during the three months ended March 31, 2019 and 2018, respectively. The interim benefit from income taxes in the three months ended March 31, 2018 was favorably impacted by the recognition of $24,634 of net deferred tax assets resulting from the Company’s decision to change the tax status and to classify most of its foreign subsidiaries as disregarded for U.S. income tax purposes. This was partially offset by a provisional $2,157 increase in income taxes payable associated with the one-time transition tax on accumulated foreign subsidiary earnings not previously subject to U.S. income tax imposed by the Tax Cuts and Jobs Act (“U.S. Tax Act”).

INCOME TAXES

In determining its interim provision for/(benefit from) income taxes, the Company uses an estimated annual effective tax rate, which is based on expected annual profit before tax, statutory tax rates and tax planning opportunities available in the various jurisdictions in which the Company operates. Certain significant or unusual items are separately recognized in the quarter in which they occur and can be a source of variability in the effective tax rates from quarter to quarter.

The Company’s worldwide effective tax rates for the three months ended March 31, 2019 and 2018 were 5.4% and (34.5)%, respectively.

The Company’s effective tax rates benefited from excess tax benefits recorded upon vesting or exercise of stock-based awards of $11,513 and $4,690 during the three months ended March 31, 2019 and 2018, respectively.

The interim benefit from income taxes in the three months ended March 31, 2018 was favorably impacted by the recognition of $24,634 of net deferred tax assets resulting from the Company’s decision to change the tax status and to classify most of its foreign subsidiaries as disregarded for U.S. income tax purposes. This was partially offset by a provisional $2,157 increase in income taxes payable associated with the one-time transition tax on accumulated foreign subsidiary earnings not previously subject to U.S. income tax imposed by the Tax Cuts and Jobs Act (“U.S. Tax Act”).
