Inventories are stated at the lower of cost and net realizable value. Cost is determined using the weighted average cost method.
The cost of finished and in process products includes the cost of raw materials, direct labor, other direct costs and manufacturing overhead expenses.
Initial costs of harvested wood are determined at fair value less cost of sale at the point of harvest.
Biological assets are transferred to inventories when forests are harvested.
Net realizable value is the estimated selling price in the ordinary course of business less the estimated costs of completion and the estimated costs necessary to make the sale.
When market conditions result in the production costs of a product exceeding its net realizable value, the inventories are written-down to their net realizable value. This write-down also includes obsolescence amounts resulting from slow moving inventories and technical obsolescence.
Spare parts that will be consumed in a period of less than twelve months are presented in inventories and recognized as an expense when they are consumed.
