Business combinations are accounted for using the purchase method. The consideration for each acquisition is measured at the aggregate of the fair values at acquisition date of assets given, liabilities incurred or assumed, and equity instruments issued by the group in exchange for control of the acquired, plus any costs directly attributable to the business combination. When a business combination agreement provides for an adjustment to the cost of the combination contingent on future events, the group includes the estimated amount of that adjustment in the cost of the combination at the acquisition date if the adjustment is probable and can be measured reliably.

Investments in equity shares which are publicly traded or where the fair value can be measured reliably are initially measured at fair value, with changes in fair value recognised in profit or loss. Investments in equity shares which are not publicly traded and where fair value cannot be measured reliably are measured at cost less impairment.
