How to compare Form ADV filing history

Start with a name, finish with an identifier

A business name is useful for discovery but weak as a final join key. An adviser may use a legal name, a doing-business-as name, or a brand shared with affiliated entities. Different firms can also have very similar names. Begin with the name you know, review the possible matches, and confirm the firm’s CRD number, main office, registration status, and official profile before carrying fields into an analysis.

The firm CRD number is the durable identifier for the adviser record. Preserve it beside normalized names and any SEC file number or other identifier. If a project combines Form ADV with EDGAR filings, do not assume that the adviser CRD and an EDGAR CIK describe exactly the same legal entity merely because their names resemble one another.

Choose the filing that answers the question

The current profile is only one view of a filing history. An adviser can submit an annual updating amendment, an other-than-annual amendment, an initial application, or a withdrawal. The right record depends on whether the question concerns the firm now, the firm at a historical date, or a change between two filings.

Record the form version, filing date, and effective or reporting period relevant to the field. A later amendment may change ownership, offices, services, client categories, regulatory assets, disciplinary answers, or private-fund details. Comparing a current field to an undated historical export can produce a precise but unrepeatable result.

• Use the latest accepted filing for a current regulatory snapshot.
• Use two identified filing versions to describe a reported change.
• Keep withdrawals and registration changes separate from ordinary amendments.

Read regulatory assets and client fields carefully

Regulatory assets under management follows the calculation framework in the Form ADV instructions. It is not automatically the same as assets displayed on a marketing site, total firm assets, or the aggregate reported value in a Form 13F information table. Label the field as regulatory assets, retain its filing date, and avoid silently substituting a broader term such as company AUM.

Client and service categories are also filer-reported regulatory disclosures. They can help define a research universe, but they do not prove commercial intent, current product usage, investment performance, or a willingness to purchase a service. A defensible market map uses these fields as qualification evidence and leaves the final interpretation to a researcher.

Follow Schedule D relationships

Schedule D expands the adviser record with private funds, related vehicles, offices, other locations, and certain service-provider relationships. For private-fund research, retain the adviser CRD, filing identifier, private-fund identifier, fund name, fund type, jurisdiction, gross asset field, minimum investment, and reported service providers together.

A private-fund name can resemble an issuer name in Form D, but name similarity is not sufficient to prove that the records describe the same vehicle or offering. Compare identifiers, addresses, related people, advisers, dates, and official documents before publishing the connection. When the evidence is incomplete, preserve the candidate match rather than converting it into a confirmed relationship.

Compare history without erasing missing states

Historical Form ADV analysis is useful because the filing is a series of dated snapshots. It can show reported changes in regulatory assets, offices, ownership, client categories, services, registrations, or private-fund records. The analysis should identify the two versions compared and calculate the change separately from the filer-reported values.

Do not collapse blank, zero, not applicable, and not reported into a single value. Those states can have different meanings in a regulatory form. A missing field may reflect a source limitation, form-version change, filing choice, or extraction gap. The safest output keeps the original state visible and explains any normalization used for analysis.

A repeatable Form ADV search checklist

A repeatable workflow records what was searched, which adviser was selected, which filing version supplied each fact, and where the source can be reviewed. This makes the result useful beyond the person who performed the first lookup.

• Search the known firm name and review legal-name variants.
• Confirm the CRD number, location, status, and official profile.
• Select a specific filing version and record its filing date.
• Interpret regulatory assets, clients, services, ownership, and disclosures under Form ADV definitions.
• Review Schedule D when the question concerns private funds or operating relationships.
• Link the conclusion to the official record and state any calculation or match assumption.
