Answer: Required return = 15%
Explanation:
Current Price using the constant-growth DDM is;
Current Price = Expected dividend / ( Required return - growth rate)
This can therefore be used to calculate the required return.
Growth rate = Return on Equity * Retention ratio
= 15% * ( 1 - payout ratio )
= 15% * (1 - 40%)
= 15% * 60%
= 9%
Expected dividend = Earnings per share * Payout ratio
= 3 * 40%
= $1.20
Using the formula;
Current Price = Expected dividend / ( Required return - growth rate)
20 = 1.20 / (Required return - 9%)
20 * (Required return - 9%) = 1.20
Required return - 9% = 1.20 / 20
Required return = (1.20 / 20) + 9%
Required return = 15%
