The rule change takes effect on April 3, 2017.
The SEC has approved FINRA’s proposed rule change to adopt a new, consolidated rule governing accounts opened or established by associated persons at firms other than the firm at which they are employed. The new rule—FINRA Rule 3210 (Accounts At Other Broker-Dealers and Financial Institutions)—helps facilitate effective oversight of such accounts. New FINRA Rule 3210 replaces NASD Rule 3050, Incorporated NYSE Rules 407 and 407A and Incorporated NYSE Rule Interpretations 407/01 and 407/02.
