Answer:
(a) WACC before tax is 7.43%
(b) WACC after tax is 5.89%
Step-by-step explanation:
WACC = Value of equity * cost of equity/ (Value of equity & debt) + Value of debt * cost of debt/ (Value of equity & debt)
Value of equity = number of share * current price = 40,000 * $81 = $3,240,000
Market value of bond = $1,100 * 8,500 = $9,350,000
Market value of equity & debt = $3,240,000 + $1,800,000 + $9,350,000 = $14,390,000
(a) WACC before tax = 3,240,000 * 15%/ 14,390,000 +1,800,000 * 6.4%/ 14,390,000 + 9,350,000 * 5%/ 14,390,000 = 7.43%
(b) If tax rate is 38%, then cost of debt is changed as below:
Cost of two-year loan = 6.4%* (1-38%) = 3.97%
Cost of bond = 5% * (1-38%) = 3.1%
WACC after tax = 3,240,000 * 15%/ 14,390,000 +1,800,000 * 3.97%/ 14,390,000 + 9,350,000 * 3.1%/ 14,390,000 = 5.89%
