ROI, Residual Income Garcia Industries produces tool and die machinery for manufacturers. The company expanded vertically in 20x1 by acquiring one of its suppliers of alloy steel plates, Keimer Steel Company. To manage the two separate businesses, the operations of Keimer are reported separately as an investment center. Garcia monitors its divisions on the basis of both unit contribution and return on average investment (ROI), with investment defined as average operating assets employed. Management bonuses are determined on ROI. All investments in operating assets are expected to earn a minimum return of 15 percent before income taxes. Keimer's cost of goods sold is considered to be entirely variable, while the division's administrative expenses are not dependent on volume. Selling expenses are a mixed cost with 40 percent attributed to sales volume. Keimer contemplated a capital acquisition with an estimated ROI of 17.50 percent; however, division management decided against the investment because it believed that the investment would decrease Keimer's overall ROI. The 20x2 operating statement for Keimer follows. The division's operating assets employed were $12,967,500 at November 30, 20x2, a 5 percent increase over the 20x1 year-end balance.
