"Audit policies and procedures for verifying the supply chain: In accordance with the Organizational Model, Ferragamo s quality control inspectors audit third parties and sub-contractors in its supply chain for any Crimes Against Individuals, including slavery and human trafficking. The Company inspectors prepare a quality control report for each supplier that includes a section explaining any findings resulting from its audit that indicate the possible exploitation of workers. The audit reports are provided to the head of the legal department for consideration and further action, if appropriate."
Ferragamo's quality control inspectors conduct audit of third parties and not audit was conducted by third parties, so the 'independent' answer has been replaced with self-reporting. And onsite visit audit is not explicitly mentioned.
