When it comes to dividends and liquidation, the owners of preferred stock have preferential treatment over the owners of common stock. Preferred stockholders receive their dividends before the common stockholders receive theirs. In other words, if the corporation does not declare and pay the dividends to preferred stock, there cannot be a dividend on the common stock. In return for these preferences, the preferred stockholders usually give up the right to share in the corporation's earnings that are in excess of their dividends.
