On Form 5500, an adviser usually appears as a plan service provider (Schedule C), not the plan sponsor.

See plans that list “AVENIR MANAGEMENT” as a service provider on 5500mcp →

Matched by name only — Form ADV and Form 5500 share no identifier, and names are searched loosely (“AVENIR MANAGEMENT” may also match similarly-named firms). Confirm identity against each filing.

Every value above is reproduced from this firm's Form ADV filing. Fields the firm left blank are shown as “Not reported” rather than filled in from other sources.
