Inventory Disclosure [Abstract]
Inventories	Inventories are valued at the lower of cost (first-in, first-out) or market. 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.

Disclosure of accounting policy for major classes of inventories, bases of stating inventories (for example, lower of cost or market), methods by which amounts are added and removed from inventory classes (for example, FIFO, LIFO, or average cost), loss recognition on impairment of inventories, and situations in which inventories are stated above cost. If inventory is carried at cost, this disclosure includes the nature of the cost elements included in inventory.
