Five years ago, Arlington Industries expanded vertically by acquiring one of its suppliers, Raddix Plastics. Arlington monitors its divisions based on both product contribution and return on investment (ROI), with investment defined as average operating assets employed. All investments in operating assets are expected to earn a minimum return of 11% before income taxes. Management bonuses are also determined based on ROI. The cost of goods sold at Raddix is fully variable while administrative expenses are not dependent on sales volume. Selling expenses are a mixed cost with 40% attributed to sales volume. Since Arlington acquired Raddix, the ROI at Raddix has ranged from 11.8% to 14.7%. During the fiscal year just ended, Raddix considered a capital acquisition with an estimated ROI of 11.5%; however, division management decided against the capital acquisition because it believed that the capital acquisition would decrease the divisions ROI. The abbreviated most recent income statement for Raddix is presented here. The divisions operating assets employed were $15,750,000 at year end, a 5% increase over the previous year-end balance
