Income Taxes [Abstract]
Income Taxes	10. INCOME TAXES During the three months ended September 30, 2013, we recognized an income tax expense of $4.6 million on pre-tax income of $17.7 million, representing an effective income tax rate of 26.2% compared to an income tax benefit of $5.4 million on pre-tax income of $39.7 million, representing an effective income tax rate of (13.6%) for the same period in 2012. During the nine months ended September 30, 2013, we recognized an income tax expense of $25.1 million on pre-tax income of $102.5 million, representing an effective income tax rate of 24.6% compared to an income tax expense of $14.6 million on pre-tax income of $149.6 million, representing an effective income tax rate of 9.8% for the same period in 2012. The increase in effective tax rate for the three and nine months ended September 30, 2013 compared to the same period in 2012 is principally the result of the release of certain valuation allowances associated with deferred tax assets that occurred in 2012 and did not reoccur in 2013. Our effective tax rates for all periods presented also differ from the federal U.S. statutory rate due to differences between income tax rates between U.S. and foreign jurisdictions. We had unrecognized tax benefits of $28.0 million at September 30, 2013 and $31.9 million at December 31, 2012. We are regularly subject to, and are currently undergoing, audits by tax authorities in the United States and foreign jurisdictions for prior tax years.

During the three months ended September 30, 2013, we recognized an income tax expense of $4.6 million on pre-tax income of $17.7 million, representing an effective income tax rate of 26.2% compared to an income tax benefit of $5.4 million on pre-tax income of $39.7 million, representing an effective income tax rate of (13.6%) for the same period in 2012. During the nine months ended September 30, 2013, we recognized an income tax expense of $25.1 million on pre-tax income of $102.5 million, representing an effective income tax rate of 24.6% compared to an income tax expense of $14.6 million on pre-tax income of $149.6 million, representing an effective income tax rate of 9.8% for the same period in 2012.

The increase in effective tax rate for the three and nine months ended September 30, 2013 compared to the same period in 2012 is principally the result of the release of certain valuation allowances associated with deferred tax assets that occurred in 2012 and did not reoccur in 2013. Our effective tax rates for all periods presented also differ from the federal U.S. statutory rate due to differences between income tax rates between U.S. and foreign jurisdictions.

We are regularly subject to, and are currently undergoing, audits by tax authorities in the United States and foreign jurisdictions for prior tax years. Please refer to Note 12 – “Commitments & Contingencies” for further details regarding these audits.
