2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES continued

s. Accounting for derivative financial instruments and hedging activities

Derivative financial instruments are initially recognised in the balance sheet at cost and subsequently are remeasured at their fair value. The method of recognising the resulting gain or loss is dependent on the nature of the item being hedged. The Group designates certain derivatives as either 1 a hedge of the fair value of a recognised asset or liability or of an unrecognised firm commitment fair value hedge; or 2 a hedge of a forecasted transaction cash flow hedge. Changes in the fair value of derivatives that are designated and qualify as fair value hedges and that are highly effective are recorded in the consolidated statement of income, along with any changes in the fair value of the hedged asset or liability that is attributable to the hedged risk. When a hedging instrument expires or is sold, or when a hedge no longer meets the criteria for hedge accounting, any cumulative gain or loss existing in equity at that time remains in equity and is recognised when the committed or forecasted transaction is ultimately recognised in the consolidated statement of income. When a committed or forecasted transaction is no longer expected to occur, the cumulative gain or loss that was reported in equity is immediately transferred to the consolidated statement of income. Changes in the fair value of derivatives that are designated and qualify as cash flow hedges and that are highly effective, are recognised in equity, in the fair value reserve account. Amounts deferred in equity are subsequently released to the consolidated statement of income and classified as revenue or expense in the periods during which the hedged forecasted transaction affects the consolidated statement of income. Changes in the fair value of any derivative instruments that do not qualify for hedge accounting are recognised immediately in the consolidated statement of income. At the inception of the transaction, the Group documents the relationship between hedging instruments and hedged items, as well as its risk management objective and strategy for undertaking various hedge transactions. This process includes linking all derivatives designated as hedges to specific assets and liabilities or to specific firm commitments or forecast transactions. The Group also documents its assessment, both at the hedge inception and on an ongoing basis, of whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in fair values or cash flows of hedged items.

t. Earnings per share

Basic earnings per share is computed by dividing net income by the weighted-average number of ordinary shares outstanding during the period or the year. Diluted earnings per share is computed by dividing net income adjusted for the interest expense and the foreign exchange gains or losses on convertible bonds, and its related tax effects, by the weighted-average number of issued and fully paid shares during the period, assuming that all options have been excercised and all the convertible bonds have been converted.

u. Segment reporting

A business segment is a distinguishable component in providing a product or service which is subject to risks and returns that are different from those of other business segments. A geographical segment is a distinguishable component in providing products or services within a particular economic environment that is subject to risks and returns that are different from those of components operating in other economic environments. The Group segments its financial reporting as follows: i business segments primary, where the Group’s business activities are classified into coal mining and trading, mining services and others power plant services and building management; and ii geographical segments secondary in which sales are classified based on target market areas.

v. Share issuance costs

Incremental costs directly attributable to the issuance of new shares are shown in equity as a deduction, net of tax, from the proceeds.

w. Difference in value from restructuring transactions of entities under common control

Restructuring transactions among entities under common control are accounted for using the pooling -of -interests method. The difference between the transfer price and the book value of each restructuring transaction among entities under common control is recorded under the account “difference in value from restructuring transactions of entities under common control” in the equity section of the consolidated financial statements.
