Answer:
Cost of common equity is 16.49%
Step-by-step explanation:
The WACC of weighted average cost of capital is the cost of a firm's capital structure. The capital structure of the firm can comprise of the following components namely debt, preferred stock and common stock.
For a firm which has only debt and equity, the WACC is calculated as follows,
WACC = wD * rD * (1 - tax rate) + wE * rE
Where,
- w represents the weight of each component
- r represents the cost of each component
- we multiply the cost of debt (rD) by (1 - tax rate) to calculate the after tax cost of debt
Plugging in the values of the available components, we can calculate the cost of common equity to be,
0.1370 = 0.3 * 0.12 * (1 - 0.4) + 0.7 * rE
0.1370 = 0.0216 + 0.7 * rE
0.1370 - 0.0216 = 0.7 * rE
0.1154 / 0.7 = rE
rE = 0.164857 or 16.4857% rounded off to 16.49%
