Income Taxes	Income Taxes The effective income tax rate for the quarter and nine months ended February 26, 2012 was 24.7 percent and 25.7 percent, respectively, compared to an effective income tax rate of 23.8 percent and 26.1 percent for the quarter and nine months ended February 27, 2011, respectively. The increase in the effective income tax rate for the quarter ended February 26, 2012 as compared to the quarter ended February 27, 2011 is primarily attributable to the fiscal 2011 impact of the favorable resolution of prior year tax matters expensed in prior years in addition to the impact of market-driven changes in the value of our trust-owned life insurance that are excluded for tax purposes, partially offset by an increase in federal income tax credits related to the Hiring Incentives to Restore Employment (HIRE) Act, an increase in the impact of FICA tax credits for employee reported tips and the impact of solar energy tax credits. The decrease in the effective income tax rate during the nine months ended February 26, 2012 as compared to the nine months ended February 27, 2011 is primarily attributable to an increase in federal income tax credits related to the HIRE Act, an increase in the impact of FICA tax credits for employee reported tips and the impact of solar energy tax credits, partially offset by the fiscal 2011 impact of the favorable resolution of prior year tax matters expensed in prior years in addition to the impact of market-driven changes in the value of our trust-owned life insurance that are excluded for tax purposes. Included in our remaining balance of unrecognized tax benefits is $1.6 million related to tax positions for which it is reasonably possible that the total amounts could change within the next twelve months based on the outcome of examinations or as a result of the expiration of the statute of limitations for specific jurisdictions.
