Income Tax Disclosure [Abstract]
Income Taxes	The Company computes its provision for income taxes by applying the estimated annual effective tax rate to income from recurring operations and adjusts the provision for discrete items recorded in the period. The Company's effective tax rate for the three and nine months ended September 30, 2012 was 4.4% and 6.5%, respectively. The Company's effective tax rate for the three and nine months ended September 30, 2011 was 15.2% and 10.0%, respectively. The provision for income taxes for the nine months ended September 30, 2012 primarily reflects the provision for income taxes for foreign and state taxes, partially offset by a tax benefit of $0.2 million resulting from the reduction of liability for uncertain tax positions in foreign jurisdictions. The provision for income taxes for the nine months ended September 30, 2011 primarily reflects the provision for income taxes for international operations and state taxes. As of September 30, 2012 and December 31, 2011, unrecognized tax benefits were $1.1 million and $1.2 million, respectively. The total amount of unrecognized tax benefits, if recognized, and in absence of full valuation allowance, would favorably impact the effective tax rate.
