Income Tax Disclosure [Abstract] |
Income Taxes | Income Taxes The tax provision for interim periods is determined using the estimated annual effective consolidated tax rate, based on the current estimate of full-year earnings before taxes, adjusted for the impact of discrete quarterly items. For both the three and six months ended June 30, 2014, our effective tax rate was 27.7%, compared with 26.5% and 24.2% for the same periods in 2013. The increase in the second-quarter effective tax rate primarily reflects the absence of the Research and Development ("R&D") tax credit in 2014 and changes in our geographic mix of earnings. The R&D tax credit was retroactively reinstated in January 2013 for two years, from January 1, 2012 through December 31, 2013, as a result of the enactment of the American Taxpayer Relief Act of 2012 (the "Taxpayer Relief Act"). The year-to-date effective tax rate increased due to the items mentioned above, as well as the impact of the $1.3 million discrete tax benefit recorded during the six months ended June 30, 2013 related to the R&D tax credit for activities completed in 2012. In accordance with U.S. GAAP, although the Taxpayer Relief Act reinstated the tax credit on a retroactive basis to January 1, 2012, the credit was not taken into account for financial reporting purposes until 2013.
