Income Taxes	9 Months Ended
Income Taxes	Sep. 30, 2014
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes. Our overall effective tax rate for the three months ended September 30, 2014 was 24.3% compared to 12.9% for the corresponding period of 2013. For the nine months ended September 30, 2014, our overall effective tax rate was 25.6%, compared to 14.0% for the corresponding period of 2013. The increase in the effective tax rate for the three and nine-month periods ended September 30, 2014 was primarily attributable to the increase in income before income taxes, resulting in a relatively lower impact of certain discrete tax benefits during the three and nine-month periods ended September 30, 2014 compared to the corresponding periods of 2013. Additionally, the effective income tax rates for the three and nine month periods ended September 30, 2014, compared to the corresponding periods of 2013, were higher as a result of a higher mix of earnings from our U.S. operations, which are taxed at a higher rate than our foreign operations.
