Income Taxes [Abstract]
Income Taxes	10. INCOME TAXES During the three months ended June 30, 2013, we recognized an income tax expense of $14.3 million on pre-tax income of $49.7 million, representing an effective income tax benefit rate of 28.8% compared to an income tax expense of $12.3 million on pre-tax income of $73.8 million, representing an effective income tax rate of 16.7% for the same period in 2012. During the six months ended June 30, 2013, we recognized an income tax expense of $20.5 million on pre-tax income of $84.8 million, representing an effective income tax benefit rate of 24.2% compared to an income tax expense of $20.0 million on pre-tax income of $109.9 million, representing an effective income tax rate of 18.2% for the same period in 2012. The increase in effective tax rate compared to the same period in 2012 is primarily the result of a shift of profits from lower tax jurisdictions to higher tax jurisdictions, losses recorded in tax jurisdictions for which no tax benefits are being recorded, and true-ups between accrued taxes and amounts included on statutory tax filings. 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 $27.9 million at June 30, 2013 and $31.9 million at December 31, 2012.

10. INCOME TAXES

During the three months ended June 30, 2013, we recognized an income tax expense of $14.3 million on pre-tax income of $49.7 million, representing an effective income tax benefit rate of 28.8% compared to an income tax expense of $12.3 million on pre-tax income of $73.8 million, representing an effective income tax rate of 16.7% for the same period in 2012. During the six months ended June 30, 2013, we recognized an income tax expense of $20.5 million on pre-tax income of $84.8 million, representing an effective income tax benefit rate of 24.2% compared to an income tax expense of $20.0 million on pre-tax income of $109.9 million, representing an effective income tax rate of 18.2% for the same period in 2012.

The increase in effective tax rate compared to the same period in 2012 is primarily the result of a shift of profits from lower tax jurisdictions to higher tax jurisdictions, losses recorded in tax jurisdictions for which no tax benefits are being recorded, and true-ups between accrued taxes and amounts included on statutory tax filings. 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 $27.9 million at June 30, 2013 and $31.9 million at December 31, 2012.
