Interactive Brokers Ireland Limited ("IBIE") custodies certain of your securities positions with its US affiliate, Interactive Brokers LLC ("IBLLC"), which is licensed by the US Securities & Exchange Commission and a member of the US Securities Investor Protection Corporation ("SIPC'). To the extent that your securities (or cash balances, to the extent they are acting as margin in support of a short stock or option position carried by IBLLC) are custodied at IBLLC, they are protected by SIPC for a maximum coverage of $500,000 (with a cash sublimit of $250,000) and under Interactive Brokers LLC's excess SIPC policy with certain underwriters at Lloyd's of London for up to an additional $30 million (with a cash sublimit of $900,000) subject to an aggregate limit of $150 million. Futures and options on futures are not covered. This coverage provides protection against failure of a broker-dealer, not against loss of market value of securities. In the unlikely event it should ever become necessary to assert a claim in a SIPC insolvency proceeding as a result of a failure of IBLLC, Interactive Brokers Ireland Limited will make the claim on your behalf.
