6. Impairment of Long-Lived Assets

If facts and circumstances indicate that a long-lived asset may be impaired, the carrying value is reviewed. If this review indicates that the carrying value of the asset will not be recovered as determined based on projected undiscounted cash flows related to the asset over its remaining life, the carrying value of the asset is reduced to its estimated fair value.  Non-cash impairment expense related to leasehold improvements and fixtures and equipment at underperforming stores totaled $0.9 million and $0.1 million in the twenty-six week periods ended August 4, 2018 and July 29, 2017, respectively.
