(i) Inventory
Inventory and work in progress are measured at the lower of cost and net realisable value. The
production cost of inventory includes an appropriate proportion of depreciation and production
overheads. Cost is determined on the following basis:
• Raw materials and consumables are measured at cost on a first in, first out (FIFO) basis or a
weighted average cost basis.
• Work in progress and finished products are measured at raw material cost, labour costs and a
proportion of production overhead expenses.
* Coal stocks are included within finished products and are measured at weighted average cost.
