What a public filing does and does not prove
- An owner may hold investments through companies, family offices or holding structures.
- A filing can show that a company owns an asset without showing the ultimate economic arrangement.
- We separate what the person owns personally, what their company owns, what they control through a holding company, what they only manage, and what has only been reported in the press.
