(A)	The Company is contractually obligated to reimburse its contract manufacturers for the cost of excess inventory that has been purchased as a result of the Company's forecasted demand when there is no alternative use. The Company's inventory deposit represents a cash deposit paid to its contract manufacturers for inventory in excess of near term demand. The deposit is recorded net of adverse purchase commitment liabilities, and therefore the net balance of the deposit represents inventory the Company believes will be utilized. The deposit will be applied against future adverse purchase commitments owed to the Company's contract manufacturers or reduced based on the usage of inventory. See Note 9 - Commitments and Contingencies for additional information regarding the Company's adverse purchase commitment liability.

Consigned inventory is held at third-party locations, including the Company's contract manufacturing partners and customers. The Company retains title to the inventory until purchased by the third-party. Consigned inventory, consisting of raw materials and finished goods, was $5.3 million and $3.0 million at September 30, 2011 and December 31, 2010.
