Rule 13h-1 – Large Trader Reporting System

The Securities and Exchange Commission ("Commission") is adopting new Rule 13h-1 and Form 13H under Section 13(h) of the Securities Exchange Act of 1934 ("Exchange Act") to establish large trader reporting requirements. The rule is intended to assist the Commission in identifying and obtaining certain baseline trading information about traders that conduct a substantial amount of trading activity, as measured by volume or market value, in the U.S. securities markets. In essence, a "large trader" will be defined as a person whose transactions in NMS securities equal or exceed (i) two million shares or $20 million during any calendar day, or (ii) 20 million shares or $200 million during any calendar month. The large trader reporting regime is designed to facilitate the Commission's ability to assess the large trader activity on the securities markets, to reconstruct trading activity following periods of unusual market volatility, and to analyze significant market events for regulatory purposes. It also should enhance the Commission's ability to detect and deter fraudulent and manipulative activity and other trading abuses, and should provide the Commission with a valuable source of useful data to study markets and market activity. The identification, recordkeeping, and reporting system will provide the Commission with a mechanism to identify large traders and their affiliates, accounts, and transactions. Specifically, Rule 13h-1 will require large traders to identify themselves to the Commission and make certain disclosures to the Commission on Form 13H. Upon receipt of Form 13H, the Commission will issue a unique identification number to the large trader, which the large trader will then provide to its registered broker-dealers. Registered broker-dealers will be required to maintain transaction records for each large trader, and will be required to report that information to the Commission upon request. In addition, certain registered broker-dealers subject to Rule 13h-1 will be required to perform limited monitoring of their customers' accounts for activity that may trigger the large trader identification requirements of Rule 13h-1.
