Worked Practitioner Scenario

Practitioner Application: CAT Reporting: Data Elements and Submission Requirements for Equities

A proprietary trading firm's automated trading system (ATS) executes thousands of equity orders daily across multiple venues. One morning, a system glitch causes a delay in transmitting order event data for a subset of these trades to the Consolidated Audit Trail (CAT). The firm's compliance officer must immediately assess the impact, identify the specific missing data elements, and determine the appropriate corrective action to avoid FINRA violations, all while adhering to strict CAT reporting deadlines. The exam question will test your ability to identify which specific data points are critical for a complete CAT submission and the consequences of their omission.

  1. The Consolidated Audit Trail (CAT) is a comprehensive, consolidated order and trade reporting system designed to create a single, accurate, and time-sequenced audit trail of all equity and option orders and trades across U.S. markets. It was established under SEC Rule 613 of Regulation NMS to enhance regulators' ability to monitor market activity, reconstruct events, and investigate misconduct. All CAT Reporters, including broker-dealers, exchanges, and alternative trading systems (ATSs), are obligated to report specific data elements for every order and trade event.
  2. Order Events: Capturing the lifecycle of an order from origination, routing, modification, cancellation, to execution. Trade Events: Reporting the actual execution details of a trade. Participant Identifiers: Unique identifiers for firms and customers involved. Timeliness: Strict deadlines for data submission.
CAT Reporters are responsible for accurately and completely reporting all required data elements. The data must be submitted to the CAT system in a prescribed format, typically through a CAT Reporting Agent or directly via an approved submission mechanism. The integrity and timeliness of this data are paramount for regulatory oversight.
