[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 three months ended May 2, 2015 and for the fiscal year ended January 31, 2015.

[3] In accordance with ASC No. 360-10, Accounting for the Impairment or Disposal of Long-Lived Assets, using an undiscounted cash flow model, we identified certain stores whose cash flow trends indicated that the carrying value of store property, equipment and leasehold improvements may not be fully recoverable and recognized impairment charges to reflect the assets at fair value. We use a discounted cash flow model to determine the fair value of our impaired assets. Key assumptions in determining future cash flows include, among other things, expected future operating performance and changes in economic conditions. Impairment charges of $0.6 million recognized during the three months ended May 2, 2015 and $0.6 million recognized during fiscal year 2014 are recorded in cost of sales and related buying, occupancy and distribution expenses.
