7. Inventory

Inventory (composed entirely of finished goods) is valued at the lower of cost or market. Cost is determined using the average cost method. The Company writes down its inventory for obsolete or excess inventory based on assumptions about future demand and market conditions. For the years ended December 31, 2011, 2010 and 2009, there were no significant charges recorded for obsolete or excess inventory.
