Income Tax Disclosure [Abstract]
Income Taxes	Note 7 — Income Taxes The effective tax rate for the current quarter was 9.1% compared to 16.5% for the quarter ended September 30, 2017. The current quarter benefitted from discrete benefits of $9.6 million primarily related to a change in tax accounting method and the release of a valuation allowance in a foreign jurisdiction. The third quarter of 2017 included a non-recurring discrete benefit of $4.2 million resulting from the reversal of reserves for uncertain tax positions. The effective tax rate for the nine months ended September 30, 2018, was 16.9% compared to 18.6% for the nine months ended September 30, 2017. The provision for the nine months ended September 30, 2018 also included a discrete benefit of $1.3 million related to the release of reserves for uncertain tax positions. The provision for the nine months ended September 30, 2017, also included nonrecurring discrete benefits of $9.1 million related to the release of a valuation allowance in a foreign jurisdiction. Excluding these discrete benefits the effective tax rates were 21.3% and 24.2%, respectively. The 2018 periods also reflect the cumulative impact of the reduction of our underlying estimated annual effective rate to 24% from 25%. Both periods benefitted from deductions associated with share-based compensation payments. The Tax Cuts and Jobs Act (the “Act”) enacted in 2017, resulted in the U.S. Federal income tax rate being reduced to 21% from 35% for the same period last year. During the measurement period, which is one year from the date of enactment, or the completion of all estimates made in connection with the Act, companies are permitted to make additional income tax adjustments and revisions of estimates related to the Act. During the quarter ended September 30, 2018, there were no material adjustments made to previously made estimates related to the Act.
