text: We reserve for obsolescence based on historical trends and specific identification. Our obsolescence reserve contains uncertainties as the 
  calculations require management to make assumptions and to apply judgment regarding a number of factors, including market conditions, 
  the selling environment, historical results and current inventory trends. 
  
  We do not believe that the assumptions used in these estimates will change significantly based on prior experience. In the past three years, 
  we have made no material changes to our estimates included in the calculations of the obsolescence reserve. A 10% change in the 
  obsolescence reserve would have had no material impact on our net earnings for the year ended January 31, 2015. 
  
  **Goodwill**
  We review our goodwill annually for impairment or when circumstances indicate its carrying value may not be recoverable. We perform this 
  evaluation at the reporting unit level, comprised of the principal business units within our Retail segment, through the application of a two- 
  step fair value test. The first step compares the carrying value of the reporting unit to its estimated fair value, which is based on the expected 
  present value of future cash flows (income approach), comparable public companies and acquisitions (market approach) or a combination of 
  both. If fair value is lower than the carrying value, then a second step is performed to quantify the amount of the impairment.
