Securities Investor Protection Corporation

The Securities Investor Protection Corporation (SIPC ) is a non-profit, member-funded, United States government corporation created under the Securities Investor Protection Act (SIPA) of 1970 that most US-registered broker-dealers are required to join. Although created by federal legislation and overseen by the Securities and Exchange Commission, the SIPC is neither a government agency nor a regulator of broker-dealers.
