INCOME TAXES

The effective income tax rate for the 12 weeks ended March 21, 2017 was 24.7%,  compared to 31.1% for the 12 weeks ended March 22, 2016. The factors that cause the effective tax rates to vary from the federal statutory rate of 35% include the impact of FICA tip and other credits, partially offset by state income taxes and certain non-deductible expenses.
