Answer:
The WACC is 6.52%
Step-by-step explanation:
The formula to compute WACC is shown below:
= Weightage of debt × cost of debt × ( 1- tax rate) + (Weightage of preferred stock) × (cost of preferred stock) + (Weightage of common stock) × (cost of common stock)
where,
Weighted of debt = Debt ÷ total firm
The total firm includes debt, preferred stock, and the equity which equals to
= $30 million + $30 million + $40 million
= $100 million
So, Weighted of debt = ($30 million ÷ $100 million) =0.3
So, the weight of preferred stock = (Preferred stock ÷ total firm)
= $30 million ÷ $100 million
= 0.3
And, the weighted of common stock = (Common stock ÷ total firm)
= $40 million ÷ $100 million
= 0.4
Now put these values to the above formula
So, the value would equal to
= (0.3 × 4%) × ( 1 - 40%) + (0.3 × 6%) + (0.4 × 10%)
= 0.72% + 1.8% + 4%
= 6.52%
