7. Inventories

 

Inventories are stated at the lower of cost or market. Cost is determined using standard costs which approximate costing determined on a first-in, first out basis. Standard costs are reviewed and adjusted periodically and at year end based on actual direct and indirect production costs. On a periodic basis, the Company reviews its inventory for estimated obsolescence or unmarketable items, primarily by reviewing future demand requirements and shelf life of the product.
