Protected up to US$600 million
The combined total of our SIPC coverage and our "excess SIPC" coverage means Schwab provides protection up to an aggregate of US$600 million, limited to a combined return of US$150 million per customer, up to US$1.15 million of which may be in cash. This protection becomes available in the event SIPC limits are exhausted.
