In a situation such as this, you can use a two-stage variation of the value driver formula for discounted cash flow (DCF) valua- tions. The first stage is based on a limited-life annuity formula, and the second stage is based on a perpetuity: CV Annuity Stage Perpetuity Stage = + such that Annuity Stage NOPAT RONIC WACC = −     −               + t A A A g g 1 1 1 1 1 1 1 − + +             = + × gA N N WACC Perpetuity Stage WACC NOP ( ) AT RONIC WACC t A N B B B g g g + + −     − ( ) 1 1 1 ( ) where  NOPAT = net operating profit after taxes gA = expected growth rate in the first stage of the CV period RONICA = expected return on new invested capital during the first stage of the CV period WACC = weighted average cost of capital N = number of years in the first stage of the CV period gB = expected growth rate in the second stage of the CV period RONICB = expected return on new invested capital during the second stage of the CV period 860  Appendix I Note that gA can take any value; it does not have to be less than the weighted average cost of capital. Conversely, gB must be less than WACC for this perpetuity formula to be valid. Otherwise the formula goes to infinity, and the company eventually overtakes the world economy. A two-stage variation can also be used for the economic-profit continuing- value formula:1 CV Economic Profit WACC NOPAT RONIC RONIC WACC = +     − + + t t A A A g 1 1 ( ) − ( )               − + +             + WACC WACC WACC g g A A N 1 1 1 NOPAT RONIC RONIC WACC WACC WACC WAC 1 1 + ( )     − ( ) − ( ) + g g g A N B B B B C ( )N These formulas assume that the return on the base level of capital remains constant. If you want to model a decline in ROIC for all capital, including the base level of capital, it is best to model this into the explicit forecast. It is difficult to model changes in average ROIC with formulas, because the growth rate in revenues and NOPAT will not equal the growth rate in free cash flow (FCF), and there are multiple ways for the ROIC to decline. You could model declining ROIC by setting the growth rate for capital and reducing NOPAT over time (in which case NOPAT will grow much more slowly than capital). Or you could set the growth rate for NOPAT and adjust FCF each period (so FCF growth again will be slower than NOPAT growth). The dynamics of these relationships are complex, and we do not recommend embedding the dynamics in continuing-value formulas, especially if the key value drivers become less transparent. 1 Thanks to Pieter de Wit and David Krieger for deriving this formula.
