Answer:
WACC = 8.98%
Step-by-step explanation:
total value of equity = $68 x 7,000,000 = $476,000,000
cost of equity:
$68 = $3.4125 / (rrr - 5%)
rrr - 5% = 5.02%
rrr = 10.02%
total value of debt:
$70 million x 0.97 = $67,900,000
YTM = {60 + [(1,000 - 970)/21]} / [(1,000 + 970)/2] = 61.43 / 985 = 6.24%
$40 million x 1.08 = $43,200,000
YTM = {65 + [(1,000 - 1,080)/6]} / [(1,000 + 1,080)/2] = 51.67 / 1,040 = 4.97%
weighted cost of debt = ($67,900,000 / $111,100,000 x 6.24%) + ($43,200,000 / $111,100,000 x 4.97%) = 3.81% + 1.93% = 5.74%
total value of the firm = $476,000,000 + $67,900,000 + $43,200,000 = $587,100,000
equity weight = $476,000,000 / $587,100,000 = 0.81076
debt weight = 1 - 0.81076 = 0.18924
WACC = (0.81076 x 10.02%) + (0.18924 x 5.74% x 0.79) = 8.12% + 0.86 = 8.98%
