SIPC was created under the Securities Investor Protection Act as a non-profit membership corporation. SIPC oversees the liquidation of member firms that close when the firm is bankrupt or in financial trouble, and customer assets are missing. In a liquidation under the Securities Investor Protection Act, SIPC and the court-appointed Trustee work to return customers’ securities and cash as quickly as possible. Within limits, SIPC expedites the return of missing customer property by protecting each customer up to $500,000 for securities and cash (including a $250,000 limit for cash only).
