Answer:
Payout ratio =1- 12.96%*45%*9/1.4 = 0.6252 or 62.52%
Explanation:
WACC = Weight of Equity * Cost of Equity + Weight of Debt * (1-Tax rate) * Cost of Debt
16% = 45%* Cost of Equity + 55%*(1-40%)*9%
16%-55%*(1-40%)*9% = 45%*Cost of Equity
Cost of Equity = 28.9556%
Current price of Stock = D1/(Cost of Equity - Growth)
25 = 4/(28.9556%-Growth)
Growth = 28.9556%-4/25 = 12.96%
ROE = Net income/Equity = 1.4/(45%*9)
Growth rate = (1- Payout ratio)*ROE
12.96% = (1-Payout ratio)* 1.4/(45%*9)
Payout ratio =1- 12.96%*45%*9/1.4 = 0.6252 or 62.52%
