To solve this problem, we should recall that the formula for Weighted Average Cost of Capital (WACC) is:
WACC = (E / V) * Re + (D / V) * Rd * (1 – Tc)
Where,
WACC = 0.132
E / V = percentage of financing or percentage of equity = 1 – percent debt = 1 – 0.3 = 0.7
Re = the cost of equity (unknown)
D / V = percentage of debt = 0.3
Rd = cost of debt
1 - Tc = corporate borrow rate = 0.08
Therefore substituting all given values into the WACC equation:
0.132 = 0.7 * Re + 0.3 * 0.08
Re = 0.1543
Answer:
The cost of equity Re is 0.1543 or 15.43%.
