Answer:
a. What are the company's capital structure weights on a book value basis?
common stocks' book value = 4,000,000 x $7 = $28,000,000
first bond = $105,000,000
second bond = $90,000,000
total book value = $223,000,000
capital structure:
common stocks = $28 / $223 = 0.1256
debt = $195 / $223 = 0.8744
b. What are the company’s capital structure weights on a market value basis?
common stocks' market value = 4,000,000 x $76 = $304,000,000
first bond = $99,750,000
second bond = $96,300,000
total book value = $500,050,000
capital structure:
common stocks = $304 / $500.05 = 0.6079
debt = $196.05 / $500.05 = 0.3921
c. Which are more relevant, the book or market value weights?
The market value is always more relevant and it is used to calculate the company's WACC.
