Best-Practice EVA

What this book actually teaches

Bennett Stewart's book makes the case for Economic Value Added (EVA) as the superior metric for measuring corporate performance and aligning management incentives. The central argument is that accounting earnings — net income, EPS, even EBITDA — systematically mislead investors and managers because they ignore the cost of the equity capital a company uses. A company can report growing earnings while actually destroying shareholder value if its return on invested capital is below its cost of capital. EVA, which subtracts a capital charge from net operating profit, corrects for this distortion.

Stewart developed EVA at Stern Stewart & Co. in the 1980s, and this book represents his mature articulation of how companies should implement and use it. The framework starts with the calculation: EVA = Net Operating Profit After Tax (NOPAT) minus a capital charge (Weighted Average Cost of Capital × Invested Capital). But the more substantive chapters cover the dozens of accounting adjustments Stewart recommends to make NOPAT and Invested Capital better reflect economic reality — capitalizing R&D rather than expensing it, adjusting for operating leases, smoothing out one-time charges that management uses to manipulate reported earnings.

The incentive compensation chapters are where the book is most distinctive. Stewart argues that executive bonuses should be tied to year-over-year EVA improvement rather than absolute EVA levels or accounting earnings, because sustainable value creation comes from continuous improvement. He also advocates for bonus banks — multi-year pools that defer a portion of earned bonuses, which can be clawed back if future performance deteriorates. This structure aligns managers with long-term shareholders rather than quarterly earnings beats.

The book's weaknesses are significant for general investors. First, it is densely practitioner-focused — the accounting adjustment tables and capital charge calculations assume considerable financial statement literacy. Second, the EVA framework, while intellectually sound, requires significant data to implement correctly, and Stewart acknowledges that the appropriate capital charge (cost of equity, in particular) involves assumptions that can drive very different conclusions. Third, the book was written in an era when EVA was being aggressively sold as a proprietary consulting framework, and the promotional undertone occasionally crowds out the analytical content.

For corporate finance practitioners, CFOs, and investors who conduct serious fundamental analysis, the core EVA insight — that capital has a cost that accounting ignores — is genuinely important and under-taught. For general equity investors, the same insight is more accessibly handled in books on return on invested capital.
