Residual Income Model
The residual income model values a company's equity by adding the present value of future residual income — earnings in excess of the cost of equity capital — to the current book value of equity. Unlike discounted cash flow models, it anchors valuation to the accounting balance sheet and measures value creation through returns that exceed the minimum required by shareholders.
The residual income model, also known as the Edwards-Bell-Ohlson model after the academics who formalized it, addresses a conceptual gap in pure discounted cash flow analysis: many companies invest heavily in the near term, depressing free cash flow, while creating substantial long-run value. The residual income framework captures this by starting with the balance sheet and adding to it the present value of all earnings that exceed what shareholders require as a return on their capital.
Residual income for any given period is calculated by subtracting the equity charge — the book value of equity multiplied by the cost of equity — from reported net income. A company earning a 15% return on equity with a 10% cost of equity is generating positive residual income. A company earning exactly its cost of equity generates zero residual income, and its intrinsic value equals book value. A company that consistently earns below its cost of capital destroys residual income and is worth less than its stated book value.
The model is commonly applied in equity research covering financial institutions, where tangible book value provides a natural anchor and return on equity is the primary performance metric. Bank analyst teams at major U.S. investment banks routinely express fair value targets for lenders like Wells Fargo and Citigroup as multiples of tangible book, with the premium or discount to book derived from the spread between expected return on tangible equity and the cost of equity.
One advantage of the residual income model is that it is directly connected to observable accounting data, making it less sensitive to terminal value assumptions than multi-decade discounted cash flow projections. However, its accuracy depends heavily on the quality and conservatism of reported earnings — a limitation that makes quality-of-earnings analysis an essential companion to the valuation exercise.
