Inventories

Inventories are stated at the lower of cost (first-in, first-out) or market (net realizable value). We evaluate our ending inventories for estimated excess quantities and obsolescence. Our evaluation includes the analysis of future sales demand by product within specific time horizons. Inventories in excess of projected future demand are written down to net realizable value. In addition, we assess the impact of changing technology on our inventory balances and write-off inventories that are considered obsolete. Write downs of inventory are recorded as a cost of products.
