subsidiaries is a first-class data block in the Topograph data model. Where shareholders describe who owns the queried company (the upstream edge), subsidiaries describe what the queried company owns (the downstream edge). A subsidiary record is always a company. It carries the equity stake the queried company holds in it, plus optional details such as voting rights, nominal capital held, and acquisition or end dates. Classification (controlled, associated, minority investment) is left to the caller and follows directly from sharePercentage.

Best practices

Topograph does not flag participations as “controlled” or “associated”. Apply your own threshold (commonly 50% for control, 20% for significant influence) so the rule stays explicit in your code.
Request shareholders and subsidiaries together to see both ends of the ownership graph for the queried company.
Records with a non-empty endDate describe past holdings. Filter them out unless you need historical context.
