Income Tax Disclosure [Abstract] |
INCOME TAX | INCOME TAX On December 22, 2017, the United States enacted the U.S. Tax Cuts and Jobs Act of 2017 (the "2017 U.S. Tax Act"). The 2017 U.S. Tax Act resulted in numerous changes, including a reduction in the U.S. federal tax rate from 35% to 21% effective January 1, 2018 and the transition of the U.S. federal tax system to a territorial regime. As of March 31, 2018, we have not completed our accounting for the effects of the 2017 U.S. Tax Act; however, we made a reasonable estimate of the effects on our existing deferred tax balances and the one-time transition tax as of December 31, 2017 pursuant to guidance provided in SEC Staff Accounting Bulletin No. 118. We did not make any adjustment to these provisional amounts during the three months ended March 31, 2018. We are continuing to gather additional information to complete our accounting for these items and expect to complete our accounting within the prescribed measurement period. Our effective income tax rates were 20.2% and 18.9% for the three months ended March 31, 2018 and March 31, 2017, respectively. Our effective income tax rate for the three months ended March 31, 2017 differs from the U.S. statutory rate primarily due to income generated in international jurisdictions with lower tax rates. 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, 2014.
