Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES The Company recorded income tax expense of $20.1 million and $7.7 million for the quarters ended March 31, 2012 and 2011, respectively. The Company's effective income tax rate was 36% and 165% for the three months ended March 31, 2012 and 2011, respectively. The Company's 2011 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 the $16.1 million noncash charge taken in connection with the Company's convertible debt. This noncash charge is not fully deductible for income tax purposes.
