text: purchase incentive arrangements are unique to each supplier and are generally annual programs ending at either the Company’s 
  fiscal year end or the supplier’s year end. Incentives are received in the form of cash or credits against purchases upon attainment of 
  specified purchase volumes and are received monthly, quarterly or annually. The incentives are generally a specified percentage of 
  the Company’s net purchases based upon achieving specific purchasing volume levels. These percentages can increase or decrease 
  based on changes in the volume of purchases. The Company accrues for the receipt of these inventory purchase incentives based 
  upon cumulative purchases of inventory. The percentage level utilized is based upon the estimated total volume of purchases 
  expected during the life of the program. Supplier programs are analyzed each quarter to determine the appropriateness of the 
  amount of purchase incentives accrued. Upon program completion, differences between estimates and actual incentives 
  subsequently received have not been material. Benefits under these supplier purchasing programs are recognized under the 
  Company’s LIFO inventory accounting method as a reduction of cost of sales when the inventories representing these purchases are 
  recorded as cost of sales. Accrued incentives expected to be settled as a credit against purchases are reported on the consolidated 
  balance sheet as an offset to amounts due to the related supplier.
