Corporate Insider such as Board Chairman is a common financial term that usually refers to C-Level executive or Vice President of a company. It can also be used as a term describing
anyone that owns more than 10% of a company's voting shares. Corporate Insider practices are regulated by the SEC to impose very strict disclosure requirements on
all insiders when they trade shares of their company on public or private exchanges.
