Business combinations – Note 31
The Group applies the acquisition method in accounting for business combinations. The cost of an acquisition is measured as the aggregate of the consideration transferred (excluding amounts relating to the settlement of pre-existing relationships), the amount of any non-controlling interest in the acquiree and, in a business combination achieved in stages, the acquisition-date fair value of the acquirer’s previously-held equity interest in the acquiree. Transaction costs that the Group incurs in connection with a business combination are expensed as incurred.
To the extent that settlement of all or any part of consideration for a business combination is deferred, the fair value of the deferred component is determined through discounting the amounts payable to their present value at the date of exchange. The discount component is unwound as an interest charge in the Consolidated Income Statement over the life of the obligation. Any contingent consideration is recognised at fair value at the acquisition date and included in the cost of the acquisition. The fair value of contingent consideration at acquisition date is arrived at through discounting the expected payment (based on scenario modelling) to present value. In general, in order for contingent consideration to become payable, pre-defined profit and/or profit/net asset ratios must be exceeded. Subsequent changes to the fair value of the contingent consideration will be recognised in profit or loss unless the contingent consideration is classified as equity, in which case it is not remeasured and settlement is accounted for within equity.
The assets and liabilities arising on business combination activity are measured at their acquisition-date fair values. Contingent liabilities assumed in business combination activity are recognised as of the acquisition date, where such contingent liabilities are present obligations arising from past events and their fair value can be measured reliably. In the case of a business combination achieved in stages, the acquisition-date fair value of the acquirer’s previously-held equity interest in the acquiree is remeasured to fair value as at the acquisition date through profit or loss. When the initial accounting for a business combination is determined provisionally, any adjustments to the provisional values allocated to the consideration, identifiable assets or liabilities (and contingent liabilities, if relevant) are made within the measurement period, a period of no more than one year from the acquisition date.
