Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES The Company recorded income tax expense of $12.2 million and $20.1 million for the quarters ended March 31, 2013 and 2012, respectively. The Company's effective income tax rate was 39% and 36% for the three months ended March 31, 2013 and 2012, respectively. The Company's 2013 income tax expense and rate differs from the amount of income tax determined by applying the U.S. Federal income tax rate to pre-tax income primarily as a result of state tax expense, expense for unrecognized tax benefits, foreign earnings, domestic production activities deduction, and tax deductible expenses related to the convertible bond repurchase. Accounting standards for income taxes provide that a tax benefit from an uncertain tax position may be recognized when it is more likely than not that the position will be sustained upon examination. The Company's unrecognized tax benefits were $15.3 million and $14.3 million as of March 31, 2013 and December 31, 2012, respectively. As of March 31, 2013, $12.2 million would affect income tax expense if recognized. The majority of the increase in unrecognized tax benefits relates to potential state tax exposures. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as a component of income tax expense. The amount of accrued interest and penalties included in the unrecognized tax benefits at March 31, 2013 and December 31, 2012 was $2.5 million and $2.4 million, respectively.
