Inventories

Inventories are valued at the lower of cost using the First-In, First-Out, or FIFO, and weighted average methods, or market. The Company's costs included in inventory primarily include pulp, resins, chemicals, direct labor, utilities, maintenance, depreciation, finishing supplies and an allocation of overhead costs. Machine start-up costs or abnormal machine shut downs are expensed in the period incurred and are not reflected in inventory. The definition of market value, with respect to all inventories, is replacement cost or net realizable value. The Company reviews inventories at least quarterly to determine the necessity of write-offs for excess, obsolete or unsalable inventory. The Company estimates write-offs for inventory obsolescence and shrinkage based on its judgment of future realization. These reviews require the Company to assess customer and market demand.
