Choosing the Right Valuation Model
All discounted cash flow models ultimately boil down to estimating four inputs -
current cashflows, an expected growth rate in these cashflows, a point in time when the
firm will be growing a rate it can sustain forever and a discount rate to use in discounting
these cashflows. In this section, we will examine the choices available in terms of each of
these inputs.
In terms of cashflows, there are three choices - dividends or free cashflows to
equity for equity valuation models, and free cashflows to the firm for firm valuation
models. Discounting dividends usually provides the most conservative estimate of value
for the equity in any firm, since most firms pay less in dividends than they can afford to.
In the dividend policy section, we noted that the free cash flow to equity, i.e., the cash
flow left over after meeting all investment needs and making debt payments, is the
amount that a firm can pay in dividends. The value of equity, based upon the free cash
flow to equity, will therefore yield a more realistic estimate of value for equity, especially
in the context of a takeover. Even if a firm is not the target of a takeover, it can be argued
that the value of equity has to reflect the possibility of a takeover, and hence the expected
free cash flows to equity. The choice between free cash flows to equity and free cash
flows to the firm is really a choice between equity and firm valuation. Done consistently,
both approaches should yield the same values for the equity in a business. As a practical
concern, however, cash flows to equity are after net debt issues or payments and become
much more difficult to estimate when financial leverage is changing over time, whereas
cashflows to the firm are pre-debt cash flows and are unaffected by changes in the
leverage. Ease of use dictates that firm valuation will be more straightforward under this
scenario.
While we can estimate any of these cashflows from the most recent financial
statements, the challenge in valuation is in estimating these cashflows in future years. In
most valuations, this takes the form of an expected growth rate in earnings that is then
used to forecast earnings and cash flows in future periods. The growth rates estimated
should be consistent with our definition of cashflows. When forecasting cashflows to
equity, we will generally forecast growth in net income or earnings per share that are
