Accounting Policy The inventory is recorded at the lower of cost and net realizable value. The cost is determined using the weighted average cost method for the purchase of raw materials. The cost of finished products and work in process comprises raw materials, labor, other direct costs (based on normal production capacity). The 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 realize the sales. Estimated losses on slow-moving or obsolete inventories are recognized when deemed necessary.
