FINRA Rule 5190

This rule sets forth notice requirements for member firms participating in offerings of securities to ensure compliance with SEC Regulation M, which regulates trading during restricted periods.

The rule requires member firms to provide written notice to FINRA of certain events, such as the pricing of a distribution, the cancellation or postponement of a distribution, and the imposition of penalty bids or engagement in syndicate covering transactions.

The notices must be provided in a specific form and within designated timeframes, and are intended to help FINRA monitor compliance with SEC Regulation M and prevent manipulative trading practices.
