The consolidated financial statements include the accounts of the Company and subsidiaries in which the Company dir ectly or indirectly has ownership of more than 50 of voting rights, or if equal to or less than 50, the Company has the ability to control the subsidiaries. The subsidiaries are consolidated from the date on which effective control is transferred to the Company and are no longer consolidated from the date of disposal. The effect of all transactions and balances between companies in the Group has been eliminated in preparing the consolidated financial statements. The accounting policies adopted in prepar ing the consolidated financial statements have been consistently applied by the subsidiaries unless otherwise stated. The accounts of the foreign operations that are integral to the Company are translated as if the foreign operations’ transactions were the Company’s own transactions. Exchange differences arising from a monetary item that, in substance, forms part of the Groups net investment in a foreign entity is classified as equity in the Group’s consolidated financial statements until the disposal of the net investment, at which time an exchange difference is recognised as income or expense.

e. Inventories

Coal inventory is valued at the lower of cost or net realisable value. Cost is determined based on the weighted average cost incurred during the period and includes an appropriate portion of fixed and variable overheads. Net realisable value is the estimated sales amount in the ordinary course of business less the costs of completion and selling expenses. Spare parts, fuel, lubricants and supplies are valued at cost, determined on a first-in, first-out basis, less provision for obsolete items. Provision for obsolete and slow moving inventory is determined on the basis of estimated future usage or sale of individual inventory items. Supplies of maintenance materials are charged to production costs in the period in which they are used.

f. Investments in debt and equity securities

Investments in equity securities that do not have readily determinable fair values are recorded using either the equity method or the cost method. Investments in equity securities in which the Group has between 20 and 50 of the voting rights and over which the Group exercises significant influence, but which it does not control, are accounted for by the equity method. Investments in equity securities in which the Group has less than 20 of the voting rights and over which the Group exercises no significant influence, are accounted for by the cost method. Under the equity method, the investment is initially recorded at cost and the carrying amount is increased or decreased to recognise the Group’s share of the profits or losses of the investee after the date of acquisition. Profit distributions except stock dividends received from the investee reduce the carrying amount of the investment. Under the cost method, the Group records its investments in investees at cost. The Group recognises income only to the extent that it receives profit distributions except stock dividends from the accumulated net profits of the investee. For investments in debt and equity securities that have readily determinable fair values, the Group classifies its investments in securities into the following categories: trading, held-to-maturity and available-for-sale. The classification is dependent on the purpose for which the investments are acquired. Management determines the classification of its investments at the time of the purchase and re-evaluates the designation on a regular basis. Investments that are acquired principally for the purpose of generating a gain from short-term maximum of three months fluctuations in price are classified as trading investments and included in current assets.
