Some information is missing on this question:
I looked for similar questions and they include a recently paid dividend of $4.75 and a growth rate of 5.2%
Answer:
8.97%
Explanation:
total value of equity = $79 x 7,000,000 = $553,000,000
cost of equity:
$79 = $4.997 / (rrr - 5.2%)
rrr - 5.2% = 6.3%
rrr = 11.5%
total value of debt:
$120 million x 0.92 = $110,400,000
YTM = {40 + [(1,000 - 920)/22]} / [(1,000 + 920)/2] = 43.64 / 960 = 4.55%
$105 million x 1.04 = $109,200,000
YTM = {30 + [(1,000 - 1,040)/7]} / [(1,000 + 1,040)/2] = 24.29 / 1,020 = 2.38%
total value of the firm = $553,000,000 + $110,400,000 + $109,200,000 = $772,600,000
equity weight = $553,000,000 / $772,600,000 = 0.7158
debt₁ weight = $110,400,000 / $772,600,000 = 0.1429
debt₂ weight = $109,200,000 / $772,600,000 = 0.1413
WACC = (0.7158 x 11.5%) + (0.1429 x 4.55% x 0.75) + (0.1413 x 2.38% x 0.75) = 8.23% + 0.49% + 0.25% = 8.97%
