Faced with headquarters' desire to add a new product line, Stefanie Regierre, manager of Lufta Products East Division, felt that she had to see the numbers before she made a move. Her division's ROI has led the company for three years, and she doesn't want any letdown. Lufta Products is a decentralized wholesaler with four autonomous divisions. The divisions are evaluated on the basis of ROI, with year-end bonuses given to divisional managers who have the highest ROI. Operating results for the company's East Division for last year are given below: Sales $29.400,000 Variable Expenses 14,480,000 Contribution Margin 14.920,000 Fixed Expenses 12,568,000 Operating Income $21352.000 Divisional Operating Assets: $7,350,000 The company had an overall ROI of 15% last year (considering all divisions). The new product line that headquarters wants Regierre's East Division to add would require an investment of $4,200,000. The cost and revenue characteristics of the new product line per year would be as follows: Sales $12,600,000 Variable Expenses 70% of sales Fixed Expenses $3.024.000 Required: A) Compute the East Division's ROI for last year, the ROI for the new product line. and the total ROI as it would appear if the new product line were added.
