Answer:
The WACC is 8.66%
Step-by-step explanation:
The WACC or weighted average cost of capital is the cost to firm of its capital structure which can have 3 components namely debt, preferred stock and common stock. We take the weighted average of these components and their respective costs to calculate WACC. Furthermore, we take the after tax cost of debt for WACC calculation and that is why we multiply the cost of debt by (1-tax rate).
WACC = wD * rD * (1-tax rate) + wP * rP + wE * rE
WACC = 0.33 * 0.065 * (1-0.28) + 0.08 * 0.06 + 0.59 * 0.1125
WACC = 0.086619 or 8.86619% rounded off to 8.66%
