Inventories

Inventories are stated at the lower of cost or net realizable value, and cost is determined by the first-in, first-out (“FIFO”) method. Manufactured inventories consist of the following costs: components, direct labor, and manufacturing overhead. Purchased inventories also include internal purchasing overhead costs. We review inventory quantities on hand and record a provision for excess and obsolete inventory based on forecasts of product demand and production requirements or historical consumption when appropriate.
