Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company’s provision for income taxes is based upon estimated annual tax rates for the year applied to federal, state and foreign income. The provision for income taxes increased to $29.9 million in the third quarter of 2014 from $22.8 million in the third quarter of 2013. The effective tax rate increased to 29.5% for the third quarter of 2014 compared to 26.3% in the third quarter of 2013 due to the recognition of discrete tax benefits in prior year and the mix of global pre-tax income among jurisdictions. The provision for income taxes increased to $89.3 million in the first nine months of 2014 from $72.8 million in the same period of 2013. The effective tax rate increased to 29.1% for the first nine months of 2014 compared to 27.9% in the same period of 2013 due to the mix of global pre-tax income among jurisdictions. Additionally, the effective tax rate for the first nine months of 2014 was favorably impacted by settlements with taxing authorities primarily related to purchase price adjustments for prior period acquisitions, while the comparable period tax rate in the prior year was favorably impacted by recognition of discrete benefits, as well as the enactment of the American Taxpayer Relief Act of 2012 on January 2, 2013, which reinstated the U.S. R&D credit retroactively to January 1, 2012. The Company and its subsidiaries file income tax returns in the U.S. federal jurisdiction, and various state and foreign jurisdictions. Due to the potential for resolution of federal, state and foreign examinations, and the expiration of various statutes of limitation, it is reasonably possible that the Company’s gross unrecognized tax benefits balance may change within the next twelve months by a range of zero to $1.0 million.
