On Form 5500, an adviser usually appears as a plan service provider (Schedule C), not the plan sponsor.
See plans that list “TETRAGON PARTNERS” as a service provider on 5500mcp →Matched by name only — Form ADV and Form 5500 share no identifier, and names are searched loosely (“TETRAGON PARTNERS” may also match similarly-named firms). Confirm identity against each filing.
