Iqaluit Corporation recently announced a bonus plan to be awarded to the vice-president of the most profitable division. The three managers are to choose whether the ROI or residual income (RI) will be used to measure profitability. In addition, they must decide whether investments will be measured using the gross book value (GBV) or net book value (NBV) of assets. Iqaluit defines income as operating income and investments as total assets. The following information is available for the year just ended: Division Gross Book Value of Assets Accumulated Depreciation Operating Income A $790,000 $395,000 $98,750 B 710,000 426,000 80,230 C 260,000 52,000 52,000 NBV ROI [A] 25.00 % [B] 28.25 % [C] 25.00 % GBV RI [A] $19,750 [B] $9,230 [C] $26,000 Iqaluit uses a required rate of return of 10% on investments to calculate RI. Calculate ROI and RI for all the three divisions by using GBV and NBV. (Round ROI to 2 decimal places, eg. 15.25%)
