We expect that our direct suppliers also comply with the laws, related to slavery and human trafficking, of their respective countries. We use a risk-based approach to determine the level of verification; auditing; certification; internal accountability; and, training that are required. GBC has an ethics code to which its employees must adhere or face disciplinary action. We expect our suppliers to maintain and enforce similar ethics codes.
