Inventories are measured at the lower of cost and net realisable value. Net realisable value represents the estimated selling price for the inventories in the ordinary course of business, less all estimated costs of completion and costs necessary to make the sale. Costs, including purchase costs, process costs, storage costs and all other costs incurred in bringing the inventories to their present location and condition, are assigned to inventories mainly by the weighted-average method. The production costs include an appropriate portion of fixed and variable overhead expenses.
