Income Tax Disclosure [Abstract]
Income Taxes	NOTE 10.Income Taxes The provision for income taxes is based on a current estimate of the annual effective income tax rate adjusted to reflect the impact of discrete items.  Our effective income tax rate was 22.5% and 32.2% for the three and nine months ended September 30, 2017, respectively, as compared to 38.4% for both the three and nine months ended September 30, 2016.  The lower tax rates for 2017 were driven primarily by the impact of domestic production activities deductions.
