Answer:
Preferred stock dividend in arrears = (12500 shares * $100 par * 6%) * 2 years
Preferred stock dividend in arrears = $150,000
Dividend paid this year = $350,000.
Dividend paid to Preferred stockholders = $150,000 in arrears + $75,000 current period = $225,000.
Dividend paid to Common Stockholders = $350,000 - $225,000 = $125,000.
Dividend per share of preferred stock = $225,000 / 12500 shares
Dividend per share of preferred stock = $18
Dividend per share of common stock = $125,000 / 25000 shares
Dividend per share of common stock = $5
