In a situation where a parent company reduces its ownership in a subsidiary from 100% to 90% but still retains control according to IFRS 10, the transaction is NOT treated as a disposal of a subsidiary; therefore, it is not an equity transaction. Instead, it is treated as a continuous involvement with the subsidiary. The carrying amounts of the assets and liabilities of the subsidiary do not change in the parent's consolidated financial statements. Non-controlling interest may be adjusted to reflect the new ownership proportion, and any difference between the amount of consideration received and the portion of the subsidiary's net assets attributed to the non-controlling interest is recognized in equity, not as a gain or loss. Thus, the FALSE statement is that a gain or loss is recorded.
