[1] The Company has recorded in other long-term liabilities amounts related to these assets for the amount due to participants corresponding in value to the securities held in the grantor trust.

[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 twenty-six weeks ended August 3, 2013 and for the fiscal year ended February 2, 2013.

[3] In accordance with ASC No. 360-10, Accounting for the Impairment or Disposal of Long-Lived Assets, using an undiscounted cash flow model, the Company 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 determined that impairment charges were necessary for the current year. The Company uses a discounted cash flow model to determine the fair value of its impaired assets. Key assumptions in determining future cash flows include, among other things, expected future operating performance and changes in economic conditions. Long-lived assets with a carrying amount of $3.6 million at August 3, 2013 and $4.0 million at February 2, 2013 were written down to their estimated fair value of $3.4 million at August 3, 2013 and $3.0 million at February 2, 2013, resulting in impairment charges of $0.2 million during the thirteen weeks ended August 3, 2013 and $1.0 million during fiscal year 2012. The impairment charges are included in cost of sales and related buying, occupancy and distribution expenses in the Condensed Consolidated Statements of Operations and Comprehensive Income (Unaudited).
