Answer and Explanation:
The computation is shown below:
a. The gain on sale is
= Book value of brand names - sales consideration
= $0 - $278 million
= -$278 million
b. Income or loss from operations
= Income from operations + gain on sale
= $165 million - $278 million
= -$113 million
c. Income from operations before impairment loss
= Income from operations + impairment loss
= $83.9 million + $13.1 million
= $103 million
d. The percentage of operating income is
= Impairment loss ÷ Income from operations before impairment loss
= $13.1 million ÷ $103 million
= 12.72%
We simply applied the above formulas
