Answer:
a. WACC of the company before bond sale = Risk Free Rate + Beta * (Market return - Risk Free rate)
= 2% + 0.80 * 10%
= 2% + 0.80*0.1
= 2% + 8%
= 10%
b. Market value of Debt after Bond sales = $40,000,000
c. Market Value of equity = Current Value of Equity + Debt * tax rate - Debt
= 50*4,000,000 + 40000000*25% - 40000000
= 200000000 + 10000000 - 40000000
= $170,000,000
d. Weight of equity = Market value of equity / Total value of equity
= 170000000 / 200000000 + 10000000
= 170000000 / 210000000
= 0.80952381
= 81%
e. Cost of debt after bond sale = YTM * (1 - tax Rate)
= 12% * 0.75
= 0.09
= 9%
f. Cost of equity after bond sale = Risk Free Rate + Beta * (Market return - Risk Free rate)
= 2% + 1.20 * 10%
= 0.02 + 0.12
= 0.14
= 14%
g. Adjusted WACC = weight of debt * Cost of debt + weight of equity * cost of equity
= 19% * 9% + 81% * 14%
= 0.0171 + 0.1134
= 0.1305
= 13.05%
