"This includes our robust assessment processes, risk mapping, and participation in industry level, third-party assessments. We also leverage predictive analytics, years of audit data, reports and guidance from internal and external experts, and feedback from third-party hotlines, surveys, and supplier employees to identify potential issues. By focusing on suppliers that cover the largest portion of our direct manufacturing spend, as well as those that are higher-risk, as identified by the activities mentioned above, we are maximizing the impact of our risk identification and prevention efforts" - page 9

Conducting Research - "We have been mapping and managing salient human rights risks in our supply chain for many years, and we continue to work with third parties, such as The Remedy Project, to deepen our understanding of how Apple’s management policies and practices align with the UNGPs, particularly related to identifying, preventing, mitigating, and remediating human rights risks and impacts. The findings from these engagements help guide continued improvements to our policies and human rights due diligence processes" - page 9

Risk-based questionnaires - "We directly engage with rights-holders through anonymous interviews, workplace satisfaction surveys, and the grievance channels we and our suppliers maintain. We recently established a new requirement in our Code whereby our suppliers must implement systems to collect feedback from and identify the needs of their employees, including in relation to wages and benefits, workplace conditions, healthcare, employee relations, living conditions, health and safety, the environment, and education and training. Suppliers are also required to take appropriate action to respond to employee feedback and communicate regularly on the progress of actions taken." - page 12

These reports also demonstrate our alignment with the UNGPs and meet regulatory requirements in Australia, California, Canada, Norway, and the United Kingdom."
