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"? 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).
