Stocks are measured at the lower of cost and estimated selling price less costs to complete and sell. Costs include all costs of purchase, costs of conversion and other costs incurred in bringing the stocks to their present location and condition.
The cost of finished goods comprises direct materials and, where applicable, direct labour costs and those overheads that have been incurred in bringing the inventories to their present location and condition. At each reporting date, stocks are assessed for impairment. If stocks are impaired, the carrying amount is reduced to its selling price less costs to complete and sell; the impairment loss is recognised immediately in profit or loss.
