30. The results of operations of a subsidiary disposed of are included in the consolidated income statement until the date of disposal which is the date on which the parent ceases to have control of the subsidiary. A subsidiary should continue to be consolidated even if its net assets are negative or the parent has the intention to either liquidate or dispose of the subsidiary in the foreseeable future. The difference between the proceeds from the disposal of the subsidiary and the carrying amount of its assets less liabilities, together with any goodwill, as of the date of disposal is recognised in the consolidated income statement as the gain or loss on the disposal of the subsidiary.
