Answer:
Part 1 - ROI
In terms of Margin :
Division Osaka = 20 %
Division Yokohama = 14 %
In terms of Turnover :
Division Osaka = 400 %
Division Yokohama = 200 %
Part 2 - Residual Income
Division Osaka = $182,000
Division Yokohama = $210,000
Explanation:
<em>Return on investment (ROI) = Divisional Profit Contribution / Assets Employed in the division x 100</em>
In terms of Margin :
Division Osaka = $ 455,000 / $ 2,275,000 x 100 = 20 %
Division Yokohama = $ 1,470,000/ $ 10,500,000 x 100 = 14 %
In terms of Turnover :
Division Osaka = $ 9,100,000 / $ 2,275,000 x 100 = 400 %
Division Yokohama = $ 21,000,000/ $ 10,500,000 x 100 = 200 %
<em>Residual income = Controllable Profit - Cost of Capital Charge on Controllable Investment</em>
Therefore,
Division Osaka = $ 455,000 - $ 2,275,000 x 12 % = $182,000
Division Yokohama = $ 1,470,000 - $ 10,500,000 x 12 % = $210,000
