The Gordon model is one of the models used in dividend valuation. It is very simple, as long as one knows the formula, which is:
P0=D1/rs-g
Where:
P0
price of the stock
D1
per share dividend expected at the end of year 1 (at the end of the next financial period)
rs
required return
g
constant growth rate
It is very important to note that if you are only given the current per share dividend (D0, per share dividend received in this financial period), then you will need to adjust it for the next financial period before you can use it in the Gordon model. To do this you will need to take the current dividend and multiply it by (1 + g). The calculation is as follows:
D1=D0*(1+g)
The original equation of the Gordon model (P0=D1/rs-g) calculates the price of the share. However, you are looking for the cost of common stock.Therefore, you need to rearrange equation of the Gordon model as follows:
rs = D1/Po + g
Now you just plug in the numbers into the adjusted Gordon equation and you will be able to obtain the cost of common stock. Because common stock is paid out of the after-tax earnings, the tax adjustment is irrelevant.
Sometimes it is necessary to find the growth rate (g) first, before you can calculate the cost of the common stock (rs) with the help of the Gordon model. To do so, you need to find out what was the per share dividends applicable to common stock over the last few years (this information will be given). After obtaining this information, you can calculate the growth rate.
It is best to explain this with the help of the example.
EXAMPLE 1:
Calculating the growth rate, which is necessary for usage of the Gordon model:
The information given below is on per share dividends applicable to common stock over the last few years. You need to find the growth rate of dividends over the given period.
Per share dividends from 2005-2010:
2010 – $4
2009 – 3.96
2008 – 3.76
2007 – 3.27
2006 – 3.25
2005 – 3
Now, by using a financial calculator , you can calculate the growth rate as follows:
PV =
-3 (per share dividend in 2005, the first year from which per share dividend information is available)
FV =
4 (per share dividend in 2010, the per share dividend in the current period)
N =
5 (number of periods over which growth occurred)
Find I =
it will be 5.92% (this number represents growth of dividends over the given period)
EXAMPLE 2:
Using the growth rate (found above) in the Gordon model:
Now, if we know that the growth of the dividends is expected to be the same into the future and the price of the stock is $55, we can compute the cost of common stock (rs) as follows:
rs=4*(1+0.0592)/55+0.0592
rs=0.0770+0.0592
rs=0.1362=0.14%
The cost of common stock also represents the return that investors expect to earn from their shares. If the actual return is less – investors will sell their stock.
Test yourself
The
ordinary share is currently sold for $40 each. The growth of shares was 10% over the last 5 years and is expected to be the same in the future. A dividend of $3.5 dollars was paid to shareholders in the current period.
REQUIRED: What is the cost of an ordinary share?
SOLUTION:
We need to use the adjusted Gordon model. In other words, we need to use the formula: rs = D1/Po + g
Rs=3.5*(1+.1)/40 +.1
Rs=3.85/40 +.1
Rs=19.63%
Note that the dividend is adjusted for growth in the next period by multiplying the current dividend by (1+g).
TEST YOURSELF:
ABC’s financial manager prepared the following information. The dividends, which were paid in the current year, were $5. The growth of dividends over the last 5 years was 7% and the same growth of dividends is expected in the future. The risk free rate is 8%, the market rate is 14% and the beta coefficient is 2.
REQUIRED: What is the market price of ABC’s ordinary shares?
SOLUTION
Firstly you need to find the required return (rs) with the help of the capital asset pricing model (CAPM).
rs= Rf+(b*(rm-Rf)
rs=8+(2*(14-8))
rs=20
Next, you need to use the Gordon model:
Po=D1/rs-g
Po=5*(1+0.07)/0.20-0.07
Po=5.35/0.13
Po=41.15
The price of the ABC’s ordinary share is $41.15. Note that you had to adjust the current dividend for the dividend in the future period by the growth rate (by multiplying current dividend by (1+g)).
