When the Company acquires a controlling financial interest through a business combination, the Company uses the acquisition method of accounting to allocate the purchase consideration to the assets acquired and liabilities assumed, which are recorded at fair value. Any excess of purchase consideration over the net fair value of the net assets acquired is recognized as goodwill. The additions of goodwill in the respective periods relate to the acquisitions made by the Company. The Company has not disposed of any entities, nor has the Company recognized impairment on the goodwill in these periods.
