Professional and Friends & Family Advisors(1) may charge their clients for services rendered either through automatic billing, electronic invoice or direct billing. You determine the advisor markup at the time of the clients registration, and may modify these markups at any time within Account Management from the Funds Management/Client Fees section. In the case of fee increases, the client will be required to acknowledge the fee increase with a signature. In addition to the advisor client fees specified, IB will charge its normal commissions to the client.
