Income Taxes	7. Income Taxes The Company recorded an income tax expense of $107,087 and $10,928 for the thirteen week periods ended September 2, 2017 and August 27, 2016, respectively, and an income tax expense of $71,878 and $4,619 for the twenty-six week periods ended September 2, 2017 and August 27, 2016, respectively. The effective tax rate for the thirteen week periods ended September 2, 2017 and August 27, 2016 was 38.5% and 42.5%, respectively. The effective tax rate for the twenty-six week periods ended September 2, 2017 and August 27, 2016 was 42.9% and 31.2%, respectively. The effective tax rate for the thirteen and twenty-six week periods ended September 2, 2017 includes an adjustment of 3.0% and 10.4%, respectively, primarily related to the tax impact of the Walgreens Boots Alliance merger termination fee. The lower effective income tax expense rate for the twenty-six week period ended August 27, 2016 is the result of a discrete income tax benefit recorded for the lapse of a statute of limitations on an uncertain tax position which lowered the Company’s effective income tax expense rate by 8.9%. The Company recognizes tax liabilities in accordance with the guidance for uncertain tax positions and management adjusts these liabilities with changes in judgment as a result of the evaluation of new information not previously available. Due to the complexity of some of these uncertainties, the ultimate resolution may result in a payment that is materially different from the current estimate of the tax liabilities. While it is expected that the amount of unrecognized tax benefits will change in the next twelve months, the Company does not expect the change to have a significant impact on the results of operations or the financial position of the Company. The Company regularly evaluates valuation allowances established for deferred tax assets for which future realization is uncertain. Management will continue to monitor all available evidence related to the net deferred tax assets that may change the most recent assessment, including events that have occurred or are anticipated to occur. The Company continues to maintain a valuation allowance against net deferred tax assets of $234,706 and $226,726, which relates primarily to state deferred tax assets at September 2, 2017 and March 4, 2017, respectively.
