All our suppliers are required to go through a Third Party Assessment before being onboarded. There is a detailed process in place to ensure that suppliers are assessed prior to being engaged, and periodically reassessed thereafter, depending on the associated risk

of the supplier. During the assessment, our specialized teams of subject matter experts review the supplier’s risk profile and the effectiveness of any control measures already in place for each

relevant risk area, including environmental, health and safety and human rights, before making recommendations to proceed with initial or continued engagement, or otherwise. Each supplier is assessed according to the use case, nature of work, geographic location and other relevant features of the engagement or intended engagement. Depending on the results of the assessment, Facebook may introduce additional control measures in the engagement. We

routinely perform ongoing third party reassessments on our suppliers depending on the applicable risks. p. 4

We verify supplier conformance with RSC policies and standards through continuous dialogue,

independent audits and assessments, corrective action plans, worker surveys, and other forms of assurance. We collect targeted metrics on the presence of migrant workers and other types of

worker demographics to find and monitor modern slavery and human trafficking risks. p. 5
