Income Tax Disclosure [Abstract] |
INCOME TAXES | INCOME TAXES The Company recorded income tax expense of $31.0 million and $51.1 million for the three and six months ended June 30, 2012, respectively, as compared to $15.0 million and $22.7 million for the three and six months ended June 30, 2011. The Company's effective income tax rate was 39% and 50% for the six months ended June 30, 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. The Company's 2012 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 supply agreement termination income and related income tax effects and the liability for unrecognized tax benefits recorded during the three months ended June 30, 2012. ASC 740 provides 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 $3.1 million and $0.0 million as of June 30, 2012 and December 31, 2011, respectively. As of June 30, 2012, $2.0 million would affect income tax expense if recognized. 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 June 30, 2012 and December 31, 2011 were $0.3 million and $0.0 million, respectively. During the three months ended June 30, 2012, the increase in unrecognized tax benefits relates to potential nexus exposure in various jurisdictions where the Company has activities.
