Income Taxes	9 Months Ended

Income Taxes [Abstract]
Income Taxes	 Note 10.      Income Taxes  Our effective income tax rate was 30.8 percent for the three months ended September 30, 2016, and 30.7 percent for the nine months ended September 30, 2016. Our effective tax rate was 31.8 percent for the three months ended September 30, 2015, and 30.8 percent for the nine months ended September 30, 2015. The decrease in our effective tax rate for the three and nine months ended September 30, 2016, as compared to the same period in the prior year, was related to the availability of the U.S. R&D tax credit, which was not available during the nine months ending September 30, 2015, as the credit had not yet been extended. In December 2015, the R&D tax credit was permanently extended with retroactive application to January 1, 2015.  As a result, we fully recognized the related 2015 tax benefit entirely in the fourth quarter of 2015.  These favorable factors were offset by a shift in earnings mix in 2016, with relatively higher earnings subject to domestic tax rates as opposed to lower international tax rates, including the impact of foreign currency exchange rates.
