We have to use trial and error to find the value of r that makes P

equal $50. It turns
out that the r implicit in these more realistic forecasts is approximately .099, quite
a difference from our “constant-growth” estimate of .21.
DCF Valuation with Varying Growth Rates
Our present value calculations for Growth-Tech used a two-stage DCF valuation
model. In the first stage (years 1 and 2), Growth-Tech is highly profitable (ROE
25 percent), and it plows back 80 percent of earnings. Book equity, earnings, and
dividends increase by 20 percent per year. In the second stage, starting in year 3,
profitability and plowback decline, and earnings settle into long-term growth at 8
percent. Dividends jump up to $1.15 in year 3, and then also grow at 8 percent.
Growth rates can vary for many reasons. Sometimes growth is high in the short
run not because the firm is unusually profitable, but because it is recovering from
an episode of low profitability. Table 4.4 displays projected earnings and dividends
for Phoenix.com, which is gradually regaining financial health after a near melt-
down. The company’s equity is growing at a moderate 4 percent. ROE in year 1 is
only 4 percent, however, so Phoenix has to reinvest all its earnings, leaving no cash
for dividends. As profitability increases in years 2 and 3, an increasing dividend
can be paid. Finally, starting in year 4, Phoenix settles into steady-state growth,
with equity, earnings, and dividends all increasing at 4 percent per year.
Assume the cost of equity is 10 percent. Then Phoenix shares should be worth
$9.13 per share:
PV (first-stage dividends) PV (second-stage dividends)
We could go on to three- or even four-stage valuation models—but you get the
idea. Two warnings, however. First, it’s almost always worthwhile to lay out a simple

TABLE 4.3
Forecasted earnings and dividends for
Growth-Tech. Note the changes in year
3: ROE and earnings drop, but payout
ratio increases, causing a big jump in
dividends. However, subsequent
growth in earnings and dividends falls
to 8 percent per year. Note that the
increase in equity equals the earnings
not paid out as dividends.
