Shareholders of CONSTRUCCIONES Y AUXILIAR DE FERROCARRILES SA
10 shareholders are currently on record for CONSTRUCCIONES Y AUXILIAR DE FERROCARRILES SA, reflecting the Libro Registro de Socios (shareholder registry book) maintained under Article 104 of the Ley de Sociedades de Capital rather than a public filing. The largest of these is Vanguard International Stock Index-Total Intl Stock Indx, holding 18% — the largest recorded stake — followed by Invesco EQV European Equity Fund at 15.2%; the remaining 8 shareholders shown hold smaller stakes.

Data availability
Those 48 subsidiaries span Spain, Poland, France, Mexico, Sweden, Italy, and 16 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. 13 of the 48 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
