(2) Income Taxes

The provisions for income taxes for both the 2015 and 2014 thirty-nine-week periods were based on estimated annual effective income tax rates of 38.2%, adjusted for discrete events, such as benefits resulting from disqualifying dispositions of the Company’s common stock by employees who obtained the stock through exercises of incentive stock options. The effective income tax rates for the 2015 and 2014 thirty-nine-week periods were 37.9% and 37.7%, respectively, which were higher than the statutory federal income tax rate primarily as a result of state taxes, the meals and entertainment exclusion and non-deductible stock-based compensation.
