Choosing between ROIC and CFROI  489 the CFROI for a division or corporate group does not easily follow from the CFROI calculations of the underlying business units. A group’s ROIC, how- ever, is simply the capital-weighted average of the returns on invested capital of the underlying businesses. An additional feature of CFROI is that, in its precise definition, it includes an adjustment for the effect of inflation on returns. The gross invested capital is indexed for inflation over the years dating to the initial purchase of the as- sets involved. For most economies in North America and Western Europe, this usually does not make a big difference. But the impact of the adjustment is significant when inflation is more than a couple of percentage points per year. In some cases, we found that this adjustment was the key source of difference between a company’s CFROI and ROIC. However, adjustments for inflation can also be made when calculating ROIC. Basically, the adjustment involves using current-year dollars to express depreciation and property, plant, and equipment (PP&E). Adjusting ROIC for inflation and using CFROI with its inflation adjust- ment typically lead to similar results across widely different inflation rates and asset lifetimes, as illustrated for a range of stylized examples in Exhibit 25.3. (See Chapter 26 for more details about inflation’s impact on ROIC and cash flows.) Differences between ROIC and CFROI could be sizable for specific busi- nesses, depending on their economics, as we saw in the preceding two ex- amples. Nevertheless, when we analyzed 1,000 U.S. companies between 2003 EXHIBIT 25.3  Returns under Inflation: ROIC vs. CFROI % Return after 20 years Inflation rate Asset life, years ROIC CFROI1 Inflation-adjusted ROIC 0 5 15 14 15 2 5 17 13 12 4 5 19 13 11 6 5 22 13 10 8 5 24 12 10 10 5 26 12 10 0 10 15 13 15 2 10 19 12 11 4 10 23 12 10 6 10 27 11 10 8 10 31 11 10 10 10 35 11 10 0 20 17 12 17 2 20 21 12 15 4 20 25 12 14 6 20 30 12 13 8 20 35 11 13 10 20 39 11 13 1 CFROI includes an inflation adjustment. 490  Alternative Ways to Measure Return on Capital and 2013, we found that, on average, these differences were not very large (see Exhibit 25.4). For all but one of the ten nonfinancial sectors we considered, the spread between the average ROIC and CFROI was three percentage points or less when taking both ROIC and CFROI without inflation adjustments. The difference between the highest- and lowest-quartile ROIC in a sector was typically four times larger than this spread. Thus, your decision whether to measure a business’s return on capital by using ROIC or CFROI is unlikely to make a difference in what the result tells you about the company’s relative performance versus that of sector peers. Flaws of Other Cash Returns on Capital In practice, we see managers and analysts apply other measures of return on capital, not just ROIC and CFROI. Sometimes the only difference is in the name.
