2.2 Common Stock and Potential Common Stock
ASC 260-10-20 defines common stock as “stock that is subordinate to all other
                stock of the issuer.” Further, potential common stock is defined as a “security or
                other contract that may entitle its holder to obtain common stock during the
                reporting period or after the end of the reporting period.” Because the valuation of
                securities that are considered potential common stock is largely derived from the
                value of the related common stock, changes in the value of those securities tend to
                reflect changes in the value of the common stock. Examples of financial instruments
                that involve potential common stock include share-based payment arrangements,
                warrants, and securities convertible into common stock. Preferred stock would not
                meet the definition of potential common stock unless it is convertible into common
                stock.
