Data-provider feed — rows as supplied to Zavia for Massachusetts Secretary of the Commonwealth, including entries the profile above does not cover. These rows are not a verbatim copy of the register: they have been found to duplicate the same person under different spellings and to keep a status of Active after an appointment ended. Where they disagree with the profile above, the profile is the checked version.

Those 22 subsidiaries span United States, Canada, Malaysia, Argentina, Thailand, Romania, and 1 more jurisdictions, though this list should not be read as complete — subsidiaries only become visible here where shareholder data has actually been filed with a register, so holdings in jurisdictions without that filing simply won't appear. Three of the 22 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
