text: The Company evaluates the recoverability of its slow moving or obsolete inventories at least quarterly. The Company estimates the 
  recoverable cost of such inventory by product type while considering factors such as its age, historic and current demand trends, the 
  physical condition of the inventory as well as assumptions regarding future demand. The Company’s ability to recover its cost for 
  slow moving or obsolete inventory can be affected by such factors as general market conditions, future customer demand and 
  relationships with suppliers. Historically, the Company’s inventories have demonstrated long shelf lives, are not highly susceptible to 
  obsolescence and are eligible for return under various supplier return programs.
