What these terms mean

What is an RIA?

A registered investment adviser is a firm whose Form ADV/IARD record reports it as registered with the SEC or, in other contexts, a state. InvestorTrustHub shows what the cited official dataset reports. Registration is a regulatory category, not a quality rating.

What is an Exempt Reporting Adviser?

An Exempt Reporting Adviser files a limited Form ADV report because it qualifies for an exemption from full SEC registration. It is not a registered investment adviser. Exemption from full registration is not a finding of safety, quality, or honesty.

What is a CRD number?

A CRD number is the Central Registration Depository identifier assigned to a firm or individual in the IARD/CRD system. InvestorTrustHub uses the firm CRD as the stable identity key. A CRD is an identifier, not an endorsement.

What is an SEC file number?

An SEC file number (often beginning 801- for registered advisers or 802- for exempt reporting advisers) is an official file identifier in SEC/IARD records. If this source record does not include one, that absence is not proof that no file number exists in another source.

What does “reported as registered” mean?

It means the cited official dataset reports the firm as a registered investment adviser as of the source date. It does not mean InvestorTrustHub or the SEC approved, certified, or recommended the firm.

What does it NOT mean?

Registration does not establish investment quality, performance, honesty, suitability, low risk, fiduciary compliance in every circumstance, or the absence of regulatory problems. Missing research is not a clean record.

What InvestorTrustHub has not researched yet

Absence from this page is not a finding that a record is clean, that no disclosure exists, or that the firm has no associated professionals.
