The easiest way to exercise a warrant is through your broker. When a warrant is exercised, the company issues new shares, increasing the total number of shares outstanding, which has a dilutive effect. Warrants can be bought and sold on the secondary market up until expiry.
The two main rules to account for stock warrants are that the issuer must recognize the fair value of the equity instruments issued or the fair value of the consideration received, whichever can be more reliably measured; and recognize the asset or expense related to the provided goods or services at the same time.
Unlike detachable warrants, undetachable ones cannot be separated from their underlying securities. This means investors who hold these types of warrants must sell both the warrants and the underlying assets at the same time.
