Dividend valuation models
Dividend valuation model: constant annual dividends
Dividend valuation method: constant rate of growth in annual dividends
Retained earnings: the earnings retention valuation model
3 Dividend valuation models
3.1 Dividend valuation model: constant annual dividends
The dividend valuation model is a more objective and cash-based approach to the
valuation of shares. Like the P/E ratio method and earnings yield method, it is an
income-based valuation method. However the valuation is based on expected future
dividends rather than on total earnings.
The basic assumption with the dividend valuation models is that the value of shares
to shareholders is the value of all the future dividends that they expect to receive
from those shares in the future.
If the fair value of a share represents the value of all expected future dividends, this
value can be estimated by discounting expected future dividends to a present value
at the shareholders’ cost of capital. All expected future dividends ‘in perpetuity’
are therefore discounted to a present value at the cost of equity capital.
Without going into the mathematics to prove the valuation model, it can be shown
that if it is assumed that the company will pay a constant annual dividend every
year into the foreseeable future, the present value of those dividends, and so the
value of the shares, is:
e
0
r
D
P =
where:
P
0
= the current value of the share ex dividend. A share price ex dividend is a price
that excludes the value of the annual dividend in the current year.
D = the amount of the annual cash dividend.
r
e
= the shareholders’ cost of capital expressed as a proportion (so 9% = 0.09, etc).
This valuation model assumes that the dividend is paid annually, and that the
current year’s dividend has just been paid. This is the assumption that is commonly
used in examination questions. For an ‘exact’ valuation using this model, it should
be assumed the next dividend is payable in one year’s time.
If the annual dividend in the current year has not yet been paid, but will soon be
paid, the value of the share is its value ‘cum dividend’. You might be asked to
suggest a cum dividend valuation, where an annual dividend will be paid in the
near future. If so, you should estimate the ex dividend price using the dividend
