Answer:
year 1:
preferred stock dividends = 24,000 x 140 x 4% = $134,400, but only $90,000 were distributed ($44,400 to be distributed next year). Dividends per preferred stock share = $90,000 / 24,000 = $3.75
common stocks dividends = no common stock dividends distributed
year 2:
preferred stock dividends = $134,400 for the current year and $44,400 form last year = $178,800. Dividends per preferred stock share = $174,800 / 24,000 = $7.45
common stocks dividends = ($188,800 - $178,800) / 80,000 common stocks = $0.125 per common stock
year 3:
preferred stock dividends = $134,400 / 24,000 = $5.60 per preferred stock.
common stocks dividends = ($227,360 - $134,400) / 80,000 = $1.162 per common stock
year 4:
preferred stock dividends = $134,400 / 24,000 = $5.60 per preferred stock.
common stocks dividends = ($243,200 - $134,400) / 80,000 = $1.36 pe common stock
