Income Tax Disclosure [Abstract]
INCOME TAX	INCOME TAX Our effective income tax rates were 15.1% and 0.0% for the three months ended June 30, 2017 and June 30, 2016, respectively. Our effective income tax rates were 16.7% and 12.9% for the six months ended June 30, 2017 and June 30, 2016, respectively. Our effective income tax rates differ from the U.S. statutory rate primarily due to income generated in international jurisdictions with lower tax rates. In addition, during the three and six months ended June 30, 2016, we recorded an income tax benefit of $12.7 million associated with the elimination of certain net deferred tax liabilities associated with undistributed earnings from Canada as a result of management's plans to reinvest these earnings outside the United States indefinitely. This income tax benefit reduced our effective income tax rates for those periods. We conduct business globally and file income tax returns in the U.S. federal jurisdiction and various state and foreign jurisdictions. In the normal course of business, we are subject to examination by taxing authorities around the world, including, without limitation, the United States and the United Kingdom. We are no longer subject to state income tax examinations for years ended on or before May 31, 2008, U.S. federal income tax examinations for fiscal years prior to 2013 and U.K. federal income tax examinations for years ended on or before May 31, 2013.
