Income Taxes [Abstract]
Income Taxes	Note 11. Income Taxes Our effective income tax rates were 23.5% and 28.0% for the three and nine months ended September 30, 2014, respectively, as compared to 29.1% and 28.9% for the three and nine months ended September 30, 2013, respectively. The decrease in our effective income tax rate for the three months ended September 30, 2014, as compared to the same period of the prior year, was related to a non-recurring benefit related to the deferral of intercompany profits that were included in prior year tax provisions in error, which is not material to current or prior interim or annual periods, and higher relative earnings subject to international tax rates that are lower than domestic tax rates. These favorable factors were partly offset by the U.S. research and development (“R&D”) tax credit which was not available during the three months ended September 30, 2014 because the legislation expired as of January 1, 2014. The decrease in our effective income tax rate for the nine months ended September 30, 2014, as compared to the same period of the prior year, was related to higher relative earnings subject to international tax rates that are lower than domestic tax rates, a non-recurring benefit related to the deferral of intercompany profits that were included in prior year tax provisions in error, which is not material to current or prior interim or annual periods, and the resolution of domestic and international tax audits, which resulted in a net reduction in our provision for uncertain tax positions. These favorable factors were partly offset by the R&D tax credit, which expired as of January 1, 2014. During the three months ended March 31, 2013, legislation in the U.S. retroactively allowed the R&D tax credit for all of 2012 and extended the R&D tax credit through the year ending December 31, 2013. Because this legislation was enacted during the three months ended March 31, 2013, the full benefit of the credit related to the prior years’ activities was recognized within that quarter.

Note 11. Income Taxes

Our effective income tax rates were 23.5% and 28.0% for the three and nine months ended September 30, 2014, respectively, as compared to 29.1% and 28.9% for the three and nine months ended September 30, 2013, respectively.

The decrease in our effective income tax rate for the three months ended September 30, 2014, as compared to the same period of the prior year, was related to a non-recurring benefit related to the deferral of intercompany profits that were included in prior year tax provisions in error, which is not material to current or prior interim or annual periods, and higher relative earnings subject to international tax rates that are lower than domestic tax rates. These favorable factors were partly offset by the U.S. research and development (“R&D”) tax credit which was not available during the three months ended September 30, 2014 because the legislation expired as of January 1, 2014.

The decrease in our effective income tax rate for the nine months ended September 30, 2014, as compared to the same period of the prior year, was related to higher relative earnings subject to international tax rates that are lower than domestic tax rates, a non-recurring benefit related to the deferral of intercompany profits that were included in prior year tax provisions in error, which is not material to current or prior interim or annual periods, and the resolution of domestic and international tax audits, which resulted in a net reduction in our provision for uncertain tax positions. These favorable factors were partly offset by the R&D tax credit, which expired as of January 1, 2014. During the three months ended March 31, 2013, legislation in the U.S. retroactively allowed the R&D tax credit for all of 2012 and extended the R&D tax credit through the year ending December 31, 2013. Because this legislation was enacted during the three months ended March 31, 2013, the full benefit of the credit related to the prior years’ activities was recognized within that quarter.
