We expect to sell the above inventory, net of reserves, at or above the stated cost and believe that no loss will be incurred on its sale.

 

Current finished goods include consigned inventory in the amounts of approximately $1,246 and $1,199 as of June 30, 2012 and December 31, 2011, respectively. Consigned inventory represents inventory at distributors and other customers where revenue recognition criteria have not been achieved.
