| Stocks are stated at the lower of cost and estimated selling price less costs to complete and sell. Cost is determined using the first-in, first-out (FIFO) method.
The cost of finished goods and work in progress 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 recognized immediately in profit or loss |
