What is indirect ownership?
A person is an indirect beneficial owner when the person's securities are held through an issuer, an affiliated issuer, a family trust, a third person
or other legal entity. Securities beneficially owned but held through a nominee such as a broker or book-based depository are considered direct
holdings.
Example: The insider is the indirect beneficial owner of securities that are held by a holding company that an insider or its subsidiaries controls.
Whenever an insider is deemed to be the beneficial owner, the insider will be an indirect beneficial owner.
