We verify supplier conformance with these standards through dialogue, independent audits and assessments,worker surveys, and other forms of assurance. Any nonconformances identified are actively addressed through our corrective action and key performance indicator programs. We are committed to engaging meaningfully and proactively with our supply chain partners, building supplier capacity, and responding quickly to challenges as they arise.

We have a Responsible Supply Chain program in place to manage social and environmental risks in our global supply

chain. Facebook requires that priority suppliers, which are identified using risk-based methodology, conform with all

of the standards on labor, health and safety, the environment, business ethics, and the establishment of

management systems in the Responsible Business Alliance (“RBA”) Code of Conduct.1
