Income Taxes	Income Taxes An estimate of the annual effective tax rate is used at each interim period based on the facts and circumstances available at that time, while the actual effective tax rate is calculated at year-end. For the 13-week periods ended July 29, 2017 and July 30, 2016, the Company recorded an income tax benefit of 33.0% and 39.6% of the loss before income taxes, respectively. For the 26-week periods ended July 29, 2017 and July 30, 2016, the Company recorded an income tax benefit of 33.9% and 39.7% of the loss before income taxes, respectively. The decrease in the tax rates for both the 13-week and 26-week periods ended July 29, 2017 was primarily due to new accounting guidance related to share-based compensation, which requires the inclusion of excess tax benefits and deficiencies as a component of income taxes. The tax rate for the 26-week period ended July 29, 2017 also decreased due to additional tax credits.
