suppliers of alloy steel plates. In order to manage the two separate businesses, the operations of Regis Steel 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 the investment defined as average operating assets used. Raddington has a policy of basing all employee bonuses on divisional ROI. All investments in operating assets are expected to earn a minimum return of 11 percent before income taxes.

Regiss cost of goods sold is considered to be entirely variable, whereas the divisions administrative expenses are not dependent on volume. Selling expenses are a mixed cost, with 40 percent attributed to sales volume. Over the last two years, Regiss ROI has ranged from 11.8 percent to 14.7 percent. During the fiscal year ended November 30, 2012, Regis contemplated a capital acquisition with an estimated ROI of 11.5 percent; however, division management decided against the investment because it believed that the investment would decrease Regiss overall ROI.

The 2012 income statement for Regis is presented next. The divisions operating assets were $15,750,000 on November 30, 2012, a 5 percent increase over the 2011 year-end balance.
