Those 60 subsidiaries span United States, Qatar, United Kingdom, Marshall Islands, Equatorial Guinea, The Bahamas 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.
