The CAT NMS Plan requires the Plan Processor to provide the SEC and Participants access to the CAT for regulatory and oversight purposes and to create a method of accessing CAT Data that includes the ability to run complex searches and generate reports. The CAT NMS Plan requires regulator access by two different methods: (a) an online targeted query tool with predefined selection criteria to choose from; and (b) extractions of data via a query tool or language allowing querying of all available attributes and data sources. Appendix D of the CAT NMS Plan sets forth additional requirements concerning regulator access.
