But for "individuals", a "straight" preferred stock, a hybrid between a bond and a stock, bears some disadvantages of each type of securities without enjoying the advantages of either. Like a bond, a straight preferred does not participate in future earnings and dividend growth of the company, or growth in the price of the common stock. However, a bond has greater security than the preferred and has a maturity date at which the principal is to be repaid. Like the common, the preferred has less security protection than the bond. However, the potential increase in the market price of the common (and its dividends, paid from future growth of the company) is lacking for the preferred. One advantage of the preferred to its issuer is that the preferred receives better equity credit at rating agencies than straight debt (since it is usually perpetual). Also, certain types of preferred stock qualify as Tier 1 capital; this allows financial institutions to satisfy regulatory requirements without diluting common shareholders. Through preferred stock, financial institutions are able to gain leverage while receiving Tier 1 equity credit.
