Warrants
In finance, a warrant is a security that entitles the holder to buy stock of the company that issued it at a specified price, which is much lower than the stock price at time of issue. Warrants are frequently attached to bonds or preferred stock as a sweetener, allowing the issuer to pay lower interest rates or dividends. They can be used to enhance the yield of the bond, and make them more attractive to potential buyers.
