Answer:
B) $8 million.
Explanation:
There are $80 worth of convertible bonds, since half of them were converted to common stocks = $80 million x 50% = $40 million
Common stock = 6 million shares x 50% x $10 (par value) = $30 million
Unamortized balance in bond discount = $4 million x 50% = $2 million
Additional paid-in capital = convertible bonds - common stock - unamortized bond discount = $40 million - $30 million - $2 million = $8 million
