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).

State Registrations and Notice Filings

Listed states reflect where the advisor is authorized to serve clients under state regulations.

IAR

means the advisor is registered as an Investment Advisor Representative in this state and is authorized to provide investment advice to clients there.

Highlighted states indicate IAR registrations

IAR

Iowa
(11/25/2025)

Don't see your state listed? The advisor may still be able to work with you under the federal De Minimis Rule, which allows up to five investment advisory clients in a state without registration. Some states, like TX, LA, NE, and NH, may still require registration or notice filing. Contact the advisor or their firm to confirm their investment advisory availability in your state.
