Answer
INCOME STATEMENT
Other Incomes
Fair value gain on assets held for sale of $5 million
Explanation:
fair value gain = fair value less costs to sell - book value
=$24mil - $19 mil
= $5 mil
The assumptions only relate to the assets held for sale's fair value and whether they are still held for sale on 31 Dec 2018 or not but the income statement will also reflect the contributions from the discontinued operations as a separate line item net of tax just below the net income from continued operations.
