Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company is subject to U.S. federal, state, and foreign income taxes. The Company's effective tax rate for the three and nine months ended September 30, 2013 was 37.4% and 36.4%, respectively. The nine month effective tax rate included, as a discrete item, the favorable impact of the enactment of The American Taxpayer Relief Act in January 2013. The American Taxpayer Relief Act included a provision to extend the income tax credit for increased research activities retroactively to the tax year ended December 31, 2012, as well as for 2013. As a result, the Company's 2012 research tax credit reduced its effective tax rate for the nine months ended September 30, 2013 by 4.3%. For the three and nine months ended September 30, 2013, the Company recorded an income tax provision of $84.4 million and $187.7 million, respectively. For the three and nine months ended September 30, 2012, income tax expense relating to the Company's pre-tax income was fully offset by a reversal of a portion of the Company's valuation allowance. As of September 30, 2012, the Company continued to recognize a full valuation allowance against its net operating loss carry-forward and other deferred tax assets since the Company had an extended history of losses. In the fourth quarter of 2012, the Company recorded an income tax benefit attributable to the release of substantially all of the remaining valuation allowance against the Company's deferred tax assets. The decision to release this valuation allowance was made after the Company determined that it was more likely than not that these deferred tax assets would be realized. Tax years subsequent to 2009 remain open to examination by federal tax authorities. In addition, New York State has commenced an examination of the Company's 2009, 2010, and 2011 tax years.
