New Jersey

Registered Investment Advisory firm - SEC (5/2/2013 Terminated)

Broker-Dealer Firm Regulated by FINRA (New York district office)

Why is a state registration marked "Terminated"? When a firm registers with the SEC (usually after managing $100M+ AUM), it often withdraws separate state firm registrations unless required by that state. The firm can still serve clients there through its individually registered Investment Advisor Representatives (IARs).
