We may indirectly have negative impact on supply chain workers through the business relationships we maintain with our suppliers as explained above. Our actions to address these potential indirect negative impacts are centered around our supply chain due diligence and assurance practices deployed through our Procurement function. Our supply chain policies described above are supported by a detailed set of internal procurement standards setting out requirements that our procurement and supplier engagement process must comply with. At the core is our risk categorisation of our suppliers. Our risk categorisation considers the type of goods and services provided, the environment in which goods and services are delivered as well as geographical risks and potential customer impact. From these criteria suppliers are grouped in high, medium and low risk categories, which determines activities undertaken during each supplier lifecycle phase: Vetting, Contracting, On-boarding, Operations and Off-boarding.
