Answer:
Option (B) is correct.
Explanation:
cost of equity, Re = Risk free rate + equity rate × market risk premium
Re = 0.03 + (1.7 × 0.8)
= 0.166R
cost of preferred stock, pfd = Dividend ÷ stock price
Rpfd = 4 ÷ 30
= 0.1333
D% = 13 billion ÷ 21 billion
= 0.619
E% = 6 billion ÷ 21 billion
= 0.286
P% = 2 billion ÷ 21 billion
= 0.095
Rd = debt capital comes from yield to maturity of 8% (YTM is an estimate of debt capital)
Tc= 30%
Rwacc =(w/ preferred stock)
= Re × E% + Rpfd × P% + Rd(1-Tc)D%
Rwacc = (0.166)(0.286) + (0.1333)(0.095) + (0.08)(1-(0.3))(0.619)
= 0.094803 ie 9.48%
Therefore, Ford's weighted average cost of capital if its tax rate is 30% is 9.48%.
