When Businesses Need Little or No Capital  479 Because ROIC is multiplied by invested capital, economic profit auto- matically corrects for any distortion in ROIC for business models with ex- tremely low capital intensity. The TradeCo example in Exhibit 24.8 illustrated this. ROIC shows very large fluctuations over the years, even becoming un- measurable in some years. In contrast, economic profit is fairly stable, just as TradeCo’s cash flows are stable and consistently positive over the years. Economic profit is a much better reflection of TradeCo’s underlying business economics. It provides more accurate insights into its historical performance and a useful basis for predicting s future performance. As economic profit is a measure of return on capital in absolute terms, it is very useful for understanding whether value creation in a particular business has increased from one year to the next. But it is harder to use for interpreting differences in economic profit generated by businesses of different sizes. Take, for example, DiversiCo in Exhibit 24.11. DiversiCo is a diversified industrial company with business units in software, hardware, hardware services, and supplies. The business units are very different in size and economics. Hard- ware, for example, has annual revenues of $2.5 billion, dwarfing the $100 mil- lion in revenues generated by software development. The software business has negative invested capital, thanks to customer prepayments, whereas hard- ware requires $1 billion in capital, mainly for manufacturing and distribution facilities and inventories. ROIC is meaningless for comparing performance across DiversiCo’s businesses, because software and hardware services have little or negative capital. Economic profit provides an accurate picture of value creation, but comparisons among businesses of such different sizes are diffi- cult. Economic profit is lowest for the software business (at $25 million), not so much because of the business’s performance, but because of its size. To better compare the value creation of DiversiCo’s businesses, scale eco- nomic profit by revenues, turning it into a measure of value creation per dol- lar of sales.10 As graphed in the final column of Exhibit 24.11, it now becomes clear that DiversiCo’s software business generates the highest value per dollar EXHIBIT 24.11  DiversiCo: Economic Profit Scaled by Revenues 25 17 10 4 25 43 73 103 n/m2 438 38 19 Invested capital Economic profit/ revenues,1 % Economic profit1 Software Hardware services Supplies Hardware (5) 10 250 1,000 NOPAT 25 44 94 188 NOPAT/ revenues, % 25 18 13 8 Revenues ROIC, % 100 250 750 2,500 1 Cost of capital equals 8.5%. 2 Not meaningful. 10 See M.

Driving revenue growth in software development would therefore be most benefi cial for shareholders. 11 Scaling economic profi t in this way provides DiversiCo’s management with a better yardstick for decisions on resource allocation and portfolio strategy. In the same way, the ratio of economic profi t over revenues can help in benchmarking performance with peers of different size and capital intensity. Consider the example of a branded-consumer-goods company, which we refer to as ReturnCo, in Exhibit 24.12 . ReturnCo is generating a ROIC of 105 per- cent, far above its international peers’ ROIC levels of around 30 to 40 percent. But this does not necessarily mean that ReturnCo creates more value and that it has some source of competitive advantage over its peers. Following our rule of thumb, ROICs above 50 percent should be interpreted with caution and carefully analyzed. In this case, it turns out that ReturnCo provides its customers with aggressive discounts for early payment. The discount pushes its earnings margins below peer levels, but the early payments make its net working capital negative and reduce its invested capital. The net result is an exceptionally high ROIC. Comparing its ROIC with those of its peers is point- less because of this difference in capital intensity, and absolute economic profi t will of course differ with the size of the competitors. Instead, an analysis of 11 Note how economic profi t over revenues is almost identical to NOPAT margin for capital-light busi- nesses, such as software and hardware services in this example. This is easily explained by examining Equation 24.2 : when invested capital is 0, the capital charge is 0, and economic profi t is equal to NOPAT.
