Answer:
9.645%
Explanation:
According to the scenario, computation of the given data are as follow:-
For calculating the marginal cost of capital we need to first calculate the following things which are given below:
Debt Weight = Market Value of Debt ÷ Total Market Value of Debt × 100
= $60 Million ÷ $300 Million × 100
= 20%
Preferred Stock Weight = Market Value of Preferred Stock ÷ Total Market Value of Preferred Stock × 100
=$30 Million ÷ $300 Million × 100
= 10%
Common Equity Weight = $210 Million ÷ $300 Million × 100 = 70%
Cost of Preferred Stock is
= Dividend ÷ Price
= 15 ÷ $85
= 17.65%
Cost of Equity is
= (Market Return - Risk Free Rate) × Beta + Risk Free Rate
= (8 - 2) × 1.20 + 2
= 6 × 1.20 + 2
= 9.2%
Now
Marginal Cost of Capital is
= Cost of Equity × Equity Weight + (1 - Tax Rate) × Debt Weight × Cost of Debt + Cost of Preferred Stock × Preferred Weight
= 9.2 × 0.70 + (1 - 0.40) × 0.20 × 12 + 17.65 × 0.10
= 6.44 + 1.44 + 1.765
= 9.645%
