23-23 (25–30 min.) ROI, RI, measurement of assets.
The method for computing profitability preferred by each manager follows:
RI based on net book value
RI based on gross book value
ROI based on either gross or net book value

Income Operating
$142,050 ÷ $1,200,000 = 11.84% (3)
$137,550 ÷ $1,140,000 = 12.07% (2)
$ 92,100 ÷ $ 750,000 = 12.28% (1)
$142,050 ÷ $555,000 = 25.59% (3)
$137,550 ÷ $525,000 = 26.20% (2)
$ 92,100 ÷ $330,000 = 27.91% (1)
Operating Income – 10% Gross BV
Operating Income – 10% Net BV1
$142,050 – $120,000 = $22,050 (2)
$137,550 – $114,000 = $23,550 (1)
$ 92,100 – $ 75,000 = $17,100 (3)
$142,050 – $55,500 = $86,550 (1)
$137,550 – $52,500 = $85,050 (2)
$ 92,100 – $33,000 = $59,100 (3)
1Net book value is gross book value minus accumulated depreciation.
The biggest weakness of ROI is the tendency to reject projects that will lower historical ROI
even though the prospective ROI exceeds the required ROI. RI achieves goal congruence
because subunits will make investments as long as they earn a rate in excess of the required
return for investments. The biggest weakness of RI is that it favors larger divisions in ranking
performance. The greater the amount of the investment (the size of the division), the more likely
that larger divisions will be favored assuming that income grows proportionately. The strength of
ROI is that it is a ratio and so does not favor larger divisions. In general, though, achieving goal
congruence is very important. Therefore, the RI measure is often preferred to ROI.
