Income Tax Disclosure [Abstract] |
Income taxes | Income Taxes The effective income tax rate for the three months ended June 30, 2012 was 16.1% compared to 20.3% for the same period in 2011. This net decrease in the effective income tax rate was primarily due to the benefit of items required to be treated discretely, such as changes in domestic and foreign uncertain tax positions, offsetting the effect of the increase in the projected and actual domestic pretax book income as compared to the prior year. The effective income tax rate for the six months ended June 30, 2012 was 18.4% compared to 17.0% for the same period in 2011. This net increase in the effective income tax rate was primarily due to the increase in the projected and actual domestic pretax book income as compared to the prior year offsetting the benefit of items required to be treated discretely, such as changes in domestic and foreign uncertain tax positions. The effective income tax rates for the three and six months ended June 30, 2012 were lower than the combined federal and state statutory rate of 38.7% primarily 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 projected annual pretax income. This was partially offset by an increase in the valuation allowance. The effective income tax rates for the three and six months ended June 30, 2011 were lower than the combined federal and state statutory rate of 38.9% due to the benefit of the expected tax credit for excess FICA tax on employee-reported tips and the foreign rate differential together being such a large percentage of projected annual pretax income. This was partially offset by an increase in the valuation allowance. As of June 30, 2012 and December 31, 2011, the Company had $11.9 million and $14.0 million, respectively, of unrecognized tax benefits ($0.9 million and $1.5 million, respectively, in “Other long-term liabilities, net,” $1.0 million and $2.5 million, respectively, in “Accrued and other current liabilities” and $10.0 million in “Deferred income tax liabilities”). Additionally, the Company accrued $2.3 million and $4.1 million of interest and penalties related to uncertain tax positions as of June 30, 2012 and December 31, 2011, respectively. Of the total amount of unrecognized tax benefits, including accrued interest and penalties, $12.1 million and $15.2 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 decrease by approximately $2.0 million to $4.0 million within the next twelve months after June 30, 2012. The Company is currently open to audit under the statute of limitations by the Internal Revenue Service 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 2011.
