I know headquarters wants us to add that new product line, said Dell Havasi, manager of Billings Companys Office Products Division. But I want to see the numbers before I make any move. Our divisions return on investment (ROI) has led the company for three years, and I dont want any letdown. Billings Company is a decentralized wholesaler with five autonomous divisions. The divisions are evaluated on the basis of ROI, with year-end bonuses given to the divisional managers who have the highest ROIs. Operating results for the companys Office Products Division for the most recent year are given below: Sales $ 22,440,000 Variable expenses 14,094,600 Contribution margin 8,345,400 Fixed expenses 6,130,000 Net operating income $ 2,215,400 Divisional operating assets $ 4,480,000 The company had an overall return on investment (ROI) of 18.00% last year (considering all divisions). The Office Products Division has an opportunity to add a new product line that would require an additional investment in operating assets of $2,430,600. The cost and revenue characteristics of the new product line per year would be: Sales $ 9,705,000 Variable expenses 65% of sales Fixed expenses $ 2,591,710 Required: 1.
