"An accredited investor is a person or entity that can deal with securities not registered with financial authorities by satisfying one of the requirements regarding income, net worth, asset size, governance status or professional experience. The term is used by the Securities and Exchange Commission (SEC) under Regulation D to refer to investors who are financially sophisticated and have a reduced need for the protection provided by regulatory disclosure filings. Accredited investors include natural individuals, banks, insurance companies, brokers and trusts."
