Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Our effective income tax rates were 31.5% and 31.5% for the nine and three months ended September 30, 2015 and 23.6% and 32.9% for the same periods in the prior year. The effective tax rate for the nine months ended September 30, 2015 is higher than the comparable prior year period primarily due to the tax benefits of $524 recorded in the second quarter of 2014 related to tax basis adjustments and settlement of the 2007-2008 and 2009-2010 federal tax audits. The effective tax rate for the three months ended September 30, 2015 is lower than the comparable prior year period primarily due to a higher U.S. manufacturing activity tax benefit than in 2014. Due to the expiration of the U.S. research and development tax credit (research tax credit) at the end of 2014, no tax benefit has been recorded in 2015. If the research tax credit is reinstated there will be a favorable impact on our 2015 effective income tax rate. Federal income tax audits have been settled for all years prior to 2011. The years 2011-2012 are currently being examined by the IRS. We are also subject to examination in major state and international jurisdictions for the 2001-2014 tax years. We believe appropriate provisions for all outstanding tax issues have been made for all jurisdictions and all open years. Audit outcomes and the timing of audit settlements are subject to significant uncertainty. It is reasonably possible that within the next 12 months we will resolve the matters presently under consideration for the 2011-2012 tax years with the IRS.

Our effective income tax rates were 31.5% and 31.5% for the nine and three months ended September 30, 2015 and 23.6% and 32.9% for the same periods in the prior year. The effective tax rate for the nine months ended September 30, 2015 is higher than the comparable prior year period primarily due to the tax benefits of $524 recorded in the second quarter of 2014 related to tax basis adjustments and settlement of the 2007-2008 and 2009-2010 federal tax audits. The effective tax rate for the three months ended September 30, 2015 is lower than the comparable prior year period primarily due to a higher U.S. manufacturing activity tax benefit than in 2014.

Due to the expiration of the U.S. research and development tax credit (research tax credit) at the end of 2014, no tax benefit has been recorded in 2015. If the research tax credit is reinstated there will be a favorable impact on our 2015 effective income tax rate.

Federal income tax audits have been settled for all years prior to 2011. The years 2011-2012 are currently being examined by the IRS. We are also subject to examination in major state and international jurisdictions for the 2001-2014 tax years. We believe appropriate provisions for all outstanding tax issues have been made for all jurisdictions and all open years.

Audit outcomes and the timing of audit settlements are subject to significant uncertainty. It is reasonably possible that within the next 12 months we will resolve the matters presently under consideration for the 2011-2012 tax years with the IRS. Depending on the timing and outcome of that audit settlement, unrecognized tax benefits could decrease by up to $125 based on current estimates.
