Answer:
12.88%
Step-by-step explanation:
The formula to compute the WACC is shown below:
= Weightage of debt × cost of debt × ( 1- tax rate) + ((Weightage of common stock) × (cost of common stock)
where,
Market Value of Equity is
= Book Value of Equity × Market to book ratio
= $10 million × 1.5
= $15 million.
Market value of debt = Face Value × Percentage of par value
= $5 million × 110%
= $5.50 million
Now
Weight of debt = Debt ÷ (Debt + Equity)
= $5.50 ÷ ($5.50 + $15)
= 26.83%
And,
Weight of equity = Equity ÷ (Debt + Equity)
= $150 ÷ ($5.50 + $15)
= 73.17%
Now the WACC is
= 26.83% × 9% × (1 - 21%) + (73.17% × 15% )
= 1.91% + 10.98
= 12.88%
