IFRS 10 states that an investor controls an investee if and only if it has all of the following:
Power over the investee
Ability to direct the relevant activities of the investee - either via majority voting rights (including potential voting rights) or rights to appoint or remove key management personnel or rights to appoint or remove another entity that directs the relevant activities or rights to direct the investee to enter into transactions that benefit of the investor
Exposure, or rights, to variable returns from its involvement with the investee
The ability to use its power to affect the amount of the investor's returns from its involvement with the investee
The identifiable assets acquired and the liabilities assumed at their fair values at the acquisition date.
Adjustments will therefore be required in Group Consolidated FS where the subsidiary's financial statements do not reflect the fair value of assets and liabilities.
Some assets or liability may not recognised by the acquiree in its individual company financial statements. However, this may be recognised by the acquirer in the consolidated financial statements.
Identifiable intangible assets, such as brand names.
(i.e. fair value of the net assets acquired exceeds the total of the consideration transferred and the value of any non-controlling interest) is recognised in profit and loss.
It may be that in some cases only provisional values can be established at the acquisition date, i.e. for the value of subsidiary's assets fair value.
Provisional values should initially be used in the calculation of goodwill.
Adjustments can be made to the fair values of the assets acquired and liabilities assumed and/or the consideration transferred made within one year of the acquisition date (i.e. measurement period).
Such adjustments should be backdated to the acquisition date and readjusted the goodwill value.
