Step-by-step explanation:
The residual income for each division will be calculated as follows:
Retail division:
Operating income = $8,000,000
Less: Minimum acceptable operating income as a percentage of invested assets = 10% × $40,000,000 = $4,000,000
Residual income = $4,000,000
Commercial division:
Operating income = $12,750,000
Less: Minimum acceptable operating income as a percentage of invested assets = 10% × $75,000,000 = $7,500,000
Residual income = $5,250,000
Internet division:
Operating income = $270,000
Less: Minimum acceptable operating income as a percentage of invested assets = 10% × $1,800,000 = $180,000
Residual income = $90,000
From the information above, we can also see that the commercial division has the highest residual value.
