Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The provision for income taxes was 27.2% and 38.6% for the three months ended June 30, 2018 and 2017, respectively. The provision for income taxes was 27.8% and 38.0% for the six months ended June 30, 2018 and 2017, respectively. The lower tax rate is primarily due to the reduction of the U.S. federal corporate income tax rate from 35% to 21% beginning in 2018. The Company recognized the income tax effects of the Tax Cuts and Jobs Act (“TCJA”) in its audited consolidated financial statements included in the Company’s 2017 Annual Report on Form 10-K in accordance with Staff Accounting Bulletin No. 118, which provides SEC staff guidance for the application of income tax guidance in the reporting period in which the TCJA was signed into law. The guidance also provides for a measurement period of up to one year from the enactment date for the Company to complete the accounting for the U.S. tax law changes. As such, the Company’s 2017 financial results reflected the provisional amounts and an estimate of the income tax effects of the TCJA. During the six months ended June 30, 2018, new guidance was released and as a result the Company recorded a charge of $3 million related to the transition tax on its total post-1986 foreign earnings and profits. The estimate of the impact of TCJA is based on certain assumptions and the Company's current interpretation, which may change, as the Company receives additional clarification and implementation guidance and as the interpretation of the TCJA evolves over time. No additional income taxes have been provided for any remaining undistributed foreign earnings not subject to the transition tax, or any additional outside basis differences inherent in our foreign entities, as the Company is still in the process of evaluating its foreign cash needs, and how much, if any, of the amount of earnings should be considered indefinitely reinvested.
