Answer:
option (B) 18.13%
Step-by-step explanation:
Given:
Cost of debt = 30%
Cost of equity = 70%
New debt will be issued at a before-tax yield = 14%
coupon rate = 10%
Required rate of return on the firm's stock = 22%
marginal tax rate = 35%
Now,
the firm's cost of capital is calculated as :
= ( Cost of Debt × (1-Tax Rate) × Weight of Debt ) + ( Cost of Equity × Required rate of return on stocks ) × 100%
on substituting the respective values, we get
= 30% × (1-0.35) × 14% + ( 70% × 22% )
or
= ( 0.3 × 0.65 × 0.14 + 0.7 × 0.22 ) × 100%
or
the firm's cost of capital = 18.13%
hence, the correct answer is option (B) 18.13%
