Inventory is measured at the lower of cost and net realizable value. The cost of inventory is based on the moving average method, and includes expenditure incurred in acquiring the inventory and the costs incurred in bringing it to its existing location and condition. Net realizable value is the estimated selling price in the ordinary course of business, less the estimated costs of completion and selling expenses. Management regularly evaluates the necessity of provisions for obsolescence, which may result from excess, slow-moving or obsolete inventories.
