ATC 9-2 (Algo) Group Assignment Return on investment versus residual income

Bellco, a division of Becker International Corporation, is operated under the direction of Antoin Sedatt. Bellco is an independent investment center with approximately $72,830,000 of assets that generate approximately $9,560,000 in annual net income. Becker International has additional investment capital of $12,900,000 that is available for the division managers to invest. Mr. Sedatt is aware of an investment opportunity that will provide an 12 percent annual net return. Becker International's desired rate of return is 11 percent.

Required

1. Assume that Mr. Sedatt's performance is evaluated based on his ability to maximize return on investment (ROI). Compute ROI using the following two assumptions: Bellco retains its current asset size and Bellco accepts and invests the additional $12,900,000 of assets. Based on ROI, should Mr. Sedatt accept or reject the opportunity to invest additional funds?
2. Assume that Mr. Sedatt's performance is evaluated based on his ability to maximize residual income. Compute residual income using the following two assumptions: Bellco retains its current asset base and Bellco accepts and invests the additional $12,900,000 of assets. Based on residual income, should Mr. Sedatt accept or reject the opportunity to invest additional funds?
3. Which technique (ROI or residual income) is more likely to result in suboptimization?
