Disclosures are events reported to regulators, such as customer disputes, regulatory actions, employment separations, or financial events. Some are resolved, denied, or contested — a disclosure is not a verdict. We recommend asking an advisor directly about any disclosure on their record.

Disclosures on record.

Disclosures can be potential red flags, including customer disputes, regulatory fines, employer terminations, bankruptcies, judgments, liens, or certain criminal activities. Check for any disclosures as part of your thorough research when choosing an advisor.

Why is a state registration marked "Terminated"?

The firm can still serve clients there through its individually registered Investment Advisor Representatives (IARs).

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.Note:This rule does not apply to broker-dealer activity.
