Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company’s effective income tax rate was 35.0% and 39.2% for the three months ended March 31, 2015 and 2014, respectively. The effective income tax rate is based on estimated income for the year, the estimated composition of the income in different jurisdictions and discrete adjustments, if any, in the applicable quarterly periods, including retroactive changes in tax legislation, settlements of tax audits or assessments, the resolution or identification of tax position uncertainties and acquisitions of other companies. For the three months ended March 31, 2015, the effective income tax rate reflects the federal statutory tax rate. The effects of accounting for stock-based compensation in accordance with the authoritative guidance for share-based payments and state income taxes cause our tax rate to be higher than the federal statutory tax rate; however, those items were offset by the domestic production activities deduction and the composition of income from foreign jurisdictions that is taxed at lower rates compared to the statutory tax rates in the U.S. For the three months ended March 31, 2014, the effective income tax rate was higher than the federal statutory tax rate mainly due to the effects of accounting for stock-based compensation in accordance with the authoritative guidance for share-based payments and state income taxes.
