Answer:
The amount of dividends paid to common stockholders in 2021 $18000.
Explanation:
The cumulative preferred stock is the stock that accumulates dividends when the dividends are partially or not paid at all in a certain year. The dividends must be paid in the future.
The common stock holders are paid after the preferred stockholders are paid.
The preferred stock dividend per year = 400000 * 0.06 = $24000 per year
As the cash dividends paid in 2019 and 2020 are $20000 each,
The dividend outstanding on preferred stocks for 2019 is = 24000 - 20000 = $4000
Similarly, the dividends outstanding on preferred stocks for 2020 is = 24000 - 20000 = $4000
The total dividends outstanding at start of 2021 = 4000 + 4000 = $8000
Preferred dividend for 2021 = 24000
Total dividend on preferred stock = 24000 + 8000 = $32000
The amount of dividends that common stock holders will receive in 2021 = 50000 - 32000 = $18000
