Data availability
Those 23 subsidiaries span United States, Kenya, Mauritius, South Korea, Barbados, Belgium, 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 23 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
