The total cash dividends are given as = $ 40,000
Since, the preferred stock is given, so first the cash dividends are allocated to the preferred stock.
The preferred stock given = $ 200,000 issued for 8 %.
The preferred dividends are calculated as = $ 200,000 × 8 % = $ 16,000
The total cash dividends = $ 40,000
The common stock dividends = Total dividends - Total preferred dividends
The common stock dividends = $ 40,000 - $ 16,000 = $ 24,000
Thus, common stock = $ 24,000, preferred dividends = $ 16,000
