A shared commitment. STE is committed to global social responsibility, ethical sourcing and a sustainable supply chain. Sales of tin, tantalum, tungsten and gold from mines controlled by armed groups in the Democratic Republic of the Congo and neighboring countries may finance ongoing conflict. STE takes this issue seriously and acts to address it. As a technology company, STE respects human rights and monitors conflict-mineral risks. We are committed to investigating our supply chain to ensure that the tin (Sn), tantalum (Ta), tungsten (W) and gold (Au) we use do not originate from mines controlled by armed groups in these regions. ### Our conflict-minerals policy 1. Do not purchase conflict metals produced in conflict regions. 2. Require suppliers to reject conflict metals from conflict regions and provide a written commitment. 3. Require suppliers to communicate these requirements to their own upstream suppliers. STE supports industry collaboration on social responsibility throughout the supply chain. We will work with customers and suppliers to find sustainable solutions to conflict-mineral risks.
