Inventory Disclosure [Abstract]

Inventories

Inventories are valued at the lower of cost (first-in, first-out) or net realizable value. Inventory costs include the cost of raw materials, packaging supplies, labor and other overhead costs. We perform a detailed review of our inventory items to determine if an obsolescence reserve adjustment is necessary. The review surveys all of our operating facilities and sales groups to ensure that both historical issues and new market trends are considered. The obsolescence reserve not only considers specific items, but also takes into consideration the overall value of the inventory as of the balance sheet date.
