3. Inventories

The Company regularly reviews inventories on hand, using specific aging categories, and writes down the carrying value of its inventories for excess and potentially obsolete inventories based on historical usage and estimated future usage. In assessing the ultimate realization of its inventories, the Company is required to make judgments as to future demand requirements. As actual future demand or market conditions may vary from those projected by the Company, adjustments to inventories may be required.
