Income Taxes [Abstract]
Income Taxes	11. INCOME TAXES During the three months ended June 30, 2014, we recognized an income tax expense of $18.7 million on pre-tax income of $42.0 million, representing an effective income tax expense rate of 44.6% compared to an income tax expense of $14.3 million on pre-tax income of $49.7 million, representing an effective income tax expense rate of 28.8% for the same period in 2013. During the six months ended June 30, 2014, we recognized an income tax expense of $24.1 million on pre-tax income of $56.5 million, representing an effective income tax expense rate of 42.6% compared to an income tax expense of $20.5 million on pre-tax income of $84.8 million, representing an effective income tax expense rate of 24.2% for the same period in 2013. The increase in effective tax rate compared to the same period in 2013 is primarily the result of increased profitability in higher tax jurisdictions and losses recorded in tax jurisdictions for which no tax benefits are being recorded partially offset by tax benefits recognized during the quarter due to the release of certain unrecognized tax benefits as a result of settling the Company’s audit with the Canada Revenue Agency. 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 and due to losses in tax jurisdictions for which no tax benefits are being recorded. We had unrecognized tax benefits of $23.0 million at June 30, 2014 and $31.6 million at December 31, 2013.

11. INCOME TAXES

During the three months ended June 30, 2014, we recognized an income tax expense of $18.7 million on pre-tax income of $42.0 million, representing an effective income tax expense rate of 44.6% compared to an income tax expense of $14.3 million on pre-tax income of $49.7 million, representing an effective income tax expense rate of 28.8% for the same period in 2013. During the six months ended June 30, 2014, we recognized an income tax expense of $24.1 million on pre-tax income of $56.5 million, representing an effective income tax expense rate of 42.6% compared to an income tax expense of $20.5 million on pre-tax income of $84.8 million, representing an effective income tax expense rate of 24.2% for the same period in 2013.

The increase in effective tax rate compared to the same period in 2013 is primarily the result of increased profitability in higher tax jurisdictions and losses recorded in tax jurisdictions for which no tax benefits are being recorded partially offset by tax benefits recognized during the quarter due to the release of certain unrecognized tax benefits as a result of settling the Company’s audit with the Canada Revenue Agency. 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 and due to losses in tax jurisdictions for which no tax benefits are being recorded. We had unrecognized tax benefits of $23.0 million at June 30, 2014 and $31.6 million at December 31, 2013.
