FINRA Rule 3110.08 provides that in the course of review and supervision of correspondences and internal communications as required under Rule 3110(b)(4), the supervisor/principal can delegate specific functions to individuals who do not need to be registered. However, the supervisor/principal remains responsible for the performance of all supervisory reviews, even if some have been delegated. This means that the supervisor/principal needs to take reasonable and appropriate actions to ensure that any delegated duties are properly executed.
