Inventories

Inventories are valued at the lower of cost or net realizable value, with cost determined by the last-in, first-out (“LIFO”) method for most inventories and first-in, first-out (“FIFO”) method for all other inventories. The company establishes a reserve for excess, slow-moving, and obsolete inventory that is equal to the difference between the cost and estimated net realizable value for that inventory. These reserves are based on a review and comparison of current inventory levels to the planned production, as well as planned and historical sales of the inventory.
