Answer:
the required rate of return i r=0.13%
Step-by-step explanation:
In order to calculate the required rate of interest in the case of a perpetual preferred stock we will use the following formula:
P(p) = D(p) / r
where P(p) is the preferred price of the stock, D(p) is the preferred dividend price and r is the required rate of interest.
This gives us the following values:
30 = 4 / r
r = 4 / 30
r = 0.13%
