Raddington 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. Raddington 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 13 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 14.5 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 $12,600,000 at November 30, 20x2, a 5 percent increase over the 20x1 year-end balance. Keimer Steel Company Operating Statement For the Year Ended November 30, 20x2 Sales revenue $25,000,000 Less expenses: Cost of goods sold Administrative expenses Selling expenses $16,500,000 3,955,000 2,700,000 23,155,000 Operating income before income taxes $1,845,000 Required: 1. Calculate the unit contribution for Keimer Steel Company if 1,187,000 units were produced and sold during the year ended November 30, 20x2. Round your answer to the nearest cent. 6.25 per unit 2. Calculate the following performance measures for 20x2 for Keimer Steel Company: a. Pretax return on average investment in operating assets employed (ROI) Residual income calculated on the basis of average operating assets employed 3. Explain why the management of Keimer Steel Company would have been more likely to accept the contemplated capital acquisition if residual income rather than ROI were used as a performance measure. The investment would have increased both the division's residual income and the management bonuses. 4. Keimer Steel Company is a separate investment center within Raddington Industries. Identify several items that Keimer should control if it is to be evaluated fairly by either the ROI or residual income performance measures. (CMA adapted) Keimer must be able to control all items related to profits and investment
