During Phase 2b of the revised implementation schedule, Industry Members will be required to report to the CAT Industry Member Data related to Eligible Securities that are options and that are related to Simple Electronic Option Orders, excluding Electronic Paired Option Orders. “Simple Electronic Option Orders” mean orders to buy or sell a single option that are not related to or dependent on any other transaction for pricing or timing of execution that are either received or routed electronically by an Industry Member CAT Reporter. A “Paired Option Order” is defined for CAT reporting purposes as an electronic simple or multi-leg option order that contains both the initial and contra side that is routed as a single message to an exchange for crossing and/or price improvement. Further, the events related to Simple Electronic Option Orders subject to reporting in Phase 2b are limited to those events which involve electronic receipt of an order, or electronic routing of an order. Electronic receipt of an order is defined as the initial receipt of an order by an Industry Member in electronic form in standard format directly into an order handling or execution system. Electronic routing of an order is the routing of an order via electronic medium in standard format from one Industry Member’s order handling or execution system to an exchange or another Industry Member.
