Answer:
WACC is 7.84%
Explanation:
First we need to calculate the after-tax cost of debt
Cost of Debt (after Tax) = Pre-tax cost of debt ( 1 - Tax rate )
Cost of Debt (after Tax) = 5.7% x ( 1 - 35% ) = 3.705%
Now calculate the cost of preferred share
Cost of preferred share = Dividend on Preferred share / Market value of preferred share
Cost of preferred share = $2.45 / $29 = 0.0845 = 8.45%
Now calculate the cost f equity
Cost of equity = Rf + Beta x Market risk premium
Cost of equity = 2.4% + 1.13 x 7.3%
Cost of equity = 2.4% + 8.249%
Cost of equity = 10.649%
Now use following formula to calclulate the WACC
WACC = ( Cost of Equity x Weight of common stock ) + ( Cost of Debt x Weight of Debt ) + ( Cost of preferred share x weight of preferred share )
WACC = ( 10.649% x 50% ) + ( 3.705% x 36% ) + ( 8.45% x 14% )
WACC = 5.3245% + 1.3338% + 1.183%
WACC = 7.8413%
