[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 items 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 nine months ended November 3, 2018 and October 28, 2017, and for the fiscal year ended February 3, 2018.

[3] 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 property, equipment and leasehold improvements may not be fully recoverable. When a store’s projected undiscounted cash flows indicate its carrying value may not be recoverable, we use a discounted cash flow model, with a 10% discount rate, to estimate the fair value of the underlying long-lived assets. An impairment write-down is recorded if the carrying value of a long-lived 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 long-lived assets. Significant changes in the key assumptions used in our cash flow projections may result in additional asset impairments. For the nine months ended November 3, 2018 and October 28, 2017, and fiscal year 2017, we recognized impairment charges of $1.1 million, $0.2 million, and $1.7 million, respectively. Impairment charges are recorded in cost of sales and related buying, occupancy and distribution expenses.
