The low-priced security surcharge is an additional commission on Stock and ETF trades when the average execution price per share in the trade is less than $1.00. For each share that is bought or sold through a real-time trade, ShareBuilder will add a $0.007 surcharge per share when the average execution price per share is less than $1.00. This surcharge is not applicable to investments made with an Automatic Investment Plan. The total commission (base commission + surcharge) is subject to a maximum of 15 percent of the principal amount of the trade, but no less than the base commission.
