Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes For interim financial reporting, we estimate the annual tax rate based on projected pre-tax income for the full year and record a quarterly income tax provision (benefit) in accordance with Accounting Standards Codification Topic 740-270, Income taxes—Interim Reporting. As the year progresses, we refine the estimate of the year's pre-tax income as new information becomes available. The continual estimation process often results in a change to the expected effective tax rate for the year. When this occurs, we adjust the income tax provision (benefit) during the quarter in which the change in estimate occurs so that the year to date provision reflects the expected annual tax rate. Our effective tax rate on income from continuing operations before income taxes was 26.9% and 24.1% for the three months ended June 30, 2015 and 2014, respectively, and 22.5% and 22.4% for the six months ended June 30, 2015 and 2014, respectively. In addition, the tax rate for all periods is lower than the U.S. statutory income tax rate of 35% due to lower statutory tax rates in certain foreign jurisdictions where we operate. As of June 30, 2015, there were no significant changes to our unrecognized tax benefits as reported in our audited financial statements for the year ended December 31, 2014.

For interim financial reporting, we estimate the annual tax rate based on projected pre-tax income for the full year and record a quarterly income tax provision (benefit) in accordance with Accounting Standards Codification Topic 740-270, Income taxes—Interim Reporting. As the year progresses, we refine the estimate of the year's pre-tax income as new information becomes available. The continual estimation process often results in a change to the expected effective tax rate for the year. When this occurs, we adjust the income tax provision (benefit) during the quarter in which the change in estimate occurs so that the year to date provision reflects the expected annual tax rate.

Our effective tax rate on income from continuing operations before income taxes was 26.9% and 24.1% for the three months ended June 30, 2015 and 2014, respectively, and 22.5% and 22.4% for the six months ended June 30, 2015 and 2014, respectively. In addition, the tax rate for all periods is lower than the U.S. statutory income tax rate of 35% due to lower statutory tax rates in certain foreign jurisdictions where we operate.
