The Securities and Exchange Commission has approved requests by both the Chicago Board Options Exchange and the International Securities Exchange to permanently extend their respective incentive programs regarding preferenced orders. These programs allow order providers to designate a Preferred Market Maker on orders sent to the exchange and entitle the Preferred Market Maker to an enhanced allocation for such orders if the Preferred Market Maker was quoting at the national best bid and offer at the time the order was received. These programs previously had been operating on a pilot basis and were scheduled to expire this month.
