A common stock is a legal claim on future Net Income after the dividend payments on the JPS, regardless that the earnings are later retained by the companies.
A JPS is a legal claim on their par value per contract and a dividend payment (fixed-income security), where it's written that the dividend may be scrapped at the BOD's discretion.
