(1) | Fiscal 2019 effective tax rate computed based on actual tax rate for the 26 weeks ended August 4, 2018.
During the 26 weeks ended August 3, 2019, the Company’s effective tax rate was lower than the US federal income tax rate primarily due to the unfavorable impact of impairment of goodwill which was not deductible for tax purposes. The forecasted annual effective tax rate excludes the effects of any discrete items that may be recognized in future periods. There has been no material change in the amounts of unrecognized tax benefits, or the related accrued interest and penalties (where appropriate), in respect of uncertain tax positions identified as of February 2, 2019.
