Prefer
red stock is in many ways like common stock but it differs from common stock in that the preferred stock holders are paid before common stock holders in profit sharing and liquidation.
Another cool aspect of preferred stock that common stock doesn’t have is the cumulative nature i.e. if dividends are not paid to a preferred stock holder then they are passed on to the next year and so on.
Even though preferred shareholders do not have voting rights, this may change in special circumstances like in the issuance of new shares, acqusition of another company, election of new directors and also when these shareholders have not been paid their dividends for a long time

And this is a major reason why public companies shy away from issuing too much of this type of stock. Another reason why preferred stock is unpopular to public companies is that ies preferred stock holders are paid with after tax dividends and this means that the company cannot get tax breaks for this stocks. This means that they are expensive for a company.
