Acquisitions And Divestitures
Business combinations	Business combinations - The acquisition method of accounting is used to account for all business combinations, irrespective of whether equity instruments or other assets are acquired. The consideration transferred for acquiring a subsidiary comprises (i) the fair values of the assets transferred; (ii) assumed liabilities of the acquired business; (iii) equity interests issued to the Company; (iv) the fair value of any asset or liability resulting from a contingent consideration arrangement; and (v) the fair value of any pre-existing equity interest in the subsidiary. Identifiable assets acquired, and liabilities and contingent liabilities assumed in a business combination are, with limited exceptions, initially measured at their fair values on the acquisition date. The Company recognizes any noncontrolling interest in the acquired entity on an acquisition-by-acquisition basis, either at fair value or at the noncontrolling interest’s proportionate share of the acquired entity’s net identifiable assets.
Discontinued operations	Discontinued operations - The designation as a discontinued operation occurs either upon disposal or when the operation meets the criteria for classification as held for sale if this condition is met earlier. A discontinued operation refers to a component of a Company's business that encompasses cash flows and operations distinguishable from the remainder of the Company, representing a significant separate line of business or geographical area of operations. The results of discontinued operations are presented in a single amount in the income statement, including the post-tax results of these operations, net of any impairment loss. Cash flows related to operating, investing, and financing activities of discontinued operations are disclosed in a separate note. Upon classifying an operation as discontinued, the income statements for prior periods are restated as if the operation had been discontinued since the beginning of the comparative period. Any noncontrolling interest associated with a group disposal held for sale is presented in equity and is not reclassified in the statement of financial position.
