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.
