Income Tax Disclosure [Abstract]
Income taxes	Income Taxes The effective income tax rate for the three months ended March 31, 2013 was 14.1% compared to 19.2% for the same period in 2012. This net decrease in the effective income tax rate as compared to the prior year was primarily due to a decrease in the projected foreign pretax book income and the foreign provision being a smaller percentage of projected consolidated pretax annual income. The effective income tax rate for the three months ended March 31, 2013 was lower than the blended federal and state statutory rate of 38.6% primarily due to the benefit of the expected tax credit for excess FICA tax on employee-reported tips, the foreign rate differential, decrease in the valuation allowance and the elimination of noncontrolling interest together being such a large percentage of projected annual pretax income. The effective income tax rate for the three months ended March 31, 2012 was lower than the blended federal and state statutory rate of 38.7% due to the benefit of the expected tax credit for excess FICA tax on employee-reported tips and the elimination of noncontrolling interest together being such a large percentage of pretax income. This was partially offset by an increase in the valuation allowance. At December 31, 2012, the Company had a valuation allowance against deferred income tax assets recorded of $72.5 million, of which $67.7 million was for U.S. deferred income tax assets. The Company has reviewed and will continue to review its conclusions about the appropriate amount of its deferred income tax asset valuation allowance in light of circumstances existing in future periods. To the extent the Company continues to generate pretax income in the U.S. in fiscal 2013 at a sufficient level, then, absent other factors indicating a contrary conclusion, the Company will consider a potential reversal of the U.S. related valuation allowance within the next nine to 12 months. Should the Company reverse the valuation allowance, a discrete tax benefit ranging from $40.0 million to $50.0 million related to the valuation allowance recorded at December 31, 2012 could be realized. Any release of valuation allowance will be recorded as a tax benefit increasing net income or as an adjustment to paid-in capital. Such reversal will impact the Company’s quarterly and annual effective income tax rates and could result in an overall income tax benefit in the period of release. The Company expects to continue to generate significant U.S. income tax credits, which combined with the mix of U.S. and foreign earnings in periods subsequent to the reversal will result in an effective income tax rate that is lower than the blended federal and state statutory rate. As of March 31, 2013 and December 31, 2012, respectively, the Company had $13.8 million and $13.6 million, respectively, of unrecognized tax benefits ($0.8 million and $1.0 million, respectively, in Other long-term liabilities, net, $0.8 million and $0.9 million, respectively, in Accrued and other current liabilities and $12.2 million and $11.7 million, respectively, in Deferred income tax liabilities). Additionally, the Company accrued $2.3 million and $2.4 million of interest and penalties related to uncertain tax positions as of March 31, 2013 and December 31, 2012, respectively. Of the total amount of unrecognized tax benefits, including accrued interest and penalties, $14.0 million and $13.8 million, respectively, if recognized, would impact the Company’s effective tax rate. The difference between the total amount of unrecognized tax benefits and the amount that would impact the effective tax rate consists of items that are offset by deferred income tax assets and the federal tax benefit of state income tax items. In many cases, the Company’s uncertain tax positions are related to tax years that remain subject to examination by relevant taxable authorities. Based on the outcome of these examinations, or as a result of the expiration of the statute of limitations for specific jurisdictions, it is reasonably possible that the related recorded unrecognized tax benefits for tax positions taken on previously filed tax returns will change by approximately $0.5 million to $0.6 million within the next twelve months after March 31, 2013. The Company is currently open to audit under the statute of limitations by the IRS for the years ended December 31, 2007 through 2011. The Company and its subsidiaries’ state and foreign income tax returns are also open to audit under the statute of limitations for the years ended December 31, 2000 through 2012. The Company is currently under examination by the Internal Revenue Service for the years ended December 31, 2009 through 2011. At this time, the Company does not believe that the outcome of any examination will have a material impact on the Company’s results of operations or financial position.

Income Taxes

The effective income tax rate for the three months ended March 31, 2013 was 14.1% compared to 19.2% for the same period in 2012. This net decrease in the effective income tax rate as compared to the prior year was primarily due to a decrease in the projected foreign pretax book income and the foreign provision being a smaller percentage of projected consolidated pretax annual income.

The effective income tax rate for the three months ended March 31, 2013 was lower than the blended federal and state statutory rate of 38.6% primarily due to the benefit of the expected tax credit for excess FICA tax on employee-reported tips, the foreign rate differential, decrease in the valuation allowance and the elimination of noncontrolling interest together being such a large percentage of projected annual pretax income. The effective income tax rate for the three months ended March 31, 2012 was lower than the blended federal and state statutory rate of 38.7% due to the benefit of the expected tax credit for excess FICA tax on employee-reported tips and the elimination of noncontrolling interest together being such a large percentage of pretax income. This was partially offset by an increase in the valuation allowance.

At December 31, 2012, the Company had a valuation allowance against deferred income tax assets recorded of $72.5 million, of which $67.7 million was for U.S. deferred income tax assets. The Company has reviewed and will continue to review its conclusions about the appropriate amount of its deferred income tax asset valuation allowance in light of circumstances existing in future periods. To the extent the Company continues to generate pretax income in the U.S. in fiscal 2013 at a sufficient level, then, absent other factors indicating a contrary conclusion, the Company will consider a potential reversal of the U.S. related valuation allowance within the next nine to 12 months. Should the Company reverse the valuation allowance, a discrete tax benefit ranging from $40.0 million to $50.0 million related to the valuation allowance recorded at December 31, 2012 could be realized. Any release of valuation allowance will be recorded as a tax benefit increasing net income or as an adjustment to paid-in capital. Such reversal will impact the Company’s quarterly and annual effective income tax rates and could result in an overall income tax benefit in the period of release. The Company expects to continue to generate significant U.S. income tax credits, which combined with the mix of U.S. and foreign earnings in periods subsequent to the reversal will result in an effective income tax rate that is lower than the blended federal and state statutory rate.

As of March 31, 2013 and December 31, 2012, respectively, the Company had $13.8 million and $13.6 million, respectively, of unrecognized tax benefits ($0.8 million and $1.0 million, respectively, in Other long-term liabilities, net, $0.8 million and $0.9 million, respectively, in Accrued and other current liabilities and $12.2 million and $11.7 million, respectively, in Deferred income tax liabilities). Additionally, the Company accrued $2.3 million and $2.4 million of interest and penalties related to uncertain tax positions as of March 31, 2013 and December 31, 2012, respectively. Of the total amount of unrecognized tax benefits, including accrued interest and penalties, $14.0 million and $13.8 million, respectively, if recognized, would impact the Company’s effective tax rate. The difference between the total amount of unrecognized tax benefits and the amount that would impact the effective tax rate consists of items that are offset by deferred income tax assets and the federal tax benefit of state income tax items.

In many cases, the Company’s uncertain tax positions are related to tax years that remain subject to examination by relevant taxable authorities. Based on the outcome of these examinations, or as a result of the expiration of the statute of limitations for specific jurisdictions, it is reasonably possible that the related recorded unrecognized tax benefits for tax positions taken on previously filed tax returns will change by approximately $0.5 million to $0.6 million within the next twelve months after March 31, 2013.
