[1] The liability for the amount due to participants corresponding in value to the securities held in the grantor trust is recorded in other long-term liabilities.

[2] Using the market approach, the fair values of these securities represent quoted market prices multiplied by the quantities held. Net gains and losses related to the changes in fair value in the assets and liabilities under the various deferred compensation plans are recorded in selling, general and administrative expenses and were nil for the six months ended August 3, 2019 and August 4, 2018, and for the fiscal year ended February 2, 2019.

[3] Assets held for sale are recorded at the asset’s fair value less estimated costs to sell and are reflected in prepaid expenses and other current assets. For the six months ended August 3, 2019, we recognized impairment charges of $1.0 million based on a third party valuation of the underlying assets. These impairment charges are recorded in selling, general and administrative expenses.

[4] Using an undiscounted cash flow model, we evaluate the cash flow trends of our stores at least annually and when events or changes in circumstances, such as a store closure, indicate that the asset group may not be fully recoverable. When a store’s projected undiscounted cash flows indicate its asset carrying value may not be recoverable, we use a discounted cash flow model to estimate the fair value of the underlying asset group. An impairment write-down is recorded if the carrying value of an asset exceeds its fair value. Key assumptions in estimating future cash flows include, among other things, expected future operating performance, including expected closure date and lease term, and changes in economic conditions. We believe estimated future cash flows are sufficient to support the carrying value of our right-of-use operating lease and long-lived assets. Significant changes in the key assumptions used in our cash flow projections may result in additional asset impairments. For the six months ended August 3, 2019 and August 4, 2018 and during fiscal year 2018, we recognized impairment charges of $0.6 million, $1.1 million, and $2.8 million, respectively. Impairment charges related to store property, equipment and leasehold improvements are recorded in cost of sales and related buying, occupancy and distribution expenses
