[1] The Company tests unamortizable intangible assets, at least annually or earlier if there are impairment indicators, by comparing the fair value and the carrying value of such assets. During this quarter, the Company impaired one of its publishing contracts due to a significant drop in current year business with that publisher, driven by lower title offerings, product quality and the loss of a distribution partner. As a result, the Company recorded an impairment charge of $3,840 in selling and administrative expenses during the 13 weeks ended January 30, 2016.
