SIPC
SIPC was created under the Securities Investor Protection Act as a non-profit membership corporation. SIPC oversees the liquidation of member broker-dealers that close when the broker-dealer is bankrupt or in financial trouble, and customer assets are missing.
SIPC is an important part of the overall system of investor protection in the United States. While a number of federal and state securities agencies and self-regulatory organizations deal with cases of investment fraud, SIPC’s focus is both different and narrow: restoring customer cash and securities left in the hands of bankrupt or otherwise financially troubled brokerage firms.
