(1) The broker's or dealer's policies regarding receipt of payment for order flow from any broker or dealer, national securities exchange, national securities association, or exchange member to which it routes customers' orders for execution, including a statement as to whether any payment for order flow is received for routing customer orders and a detailed description of the nature of the compensation received; and

(2) The broker's or dealer's policies for determining where to route customer orders that are the subject of payment for order flow absent specific instructions from customers, including a description of the extent to which orders can be executed at prices superior to the national best bid and national best offer.
