AMB is committed to the responsible sourcing of minerals through our supply chain. AMB works with our supply chain to trace potential sources of minerals such as tantalum, tin, gold or tungsten, which are known to help finance conflict and contribute to the humanitarian crisis in the Democratic Republic of the Congo (DRC) and the DRC’s adjoining countries.

AMB currently focuses its compliance efforts in the following areas:

• Conducting a reasonable country of origin inquiry with our supply base as part of our conflict minerals due diligence process.

• We request suppliers to identify products in their supply chain that contain conflict minerals and validate the country of origin of these minerals.

• Including a contractual clause related to conflict minerals in new or renewed U.S. and non-U.S. supplier contracts as part of our standard Terms and Conditions.

• Requiring our suppliers to comply with any applicable laws and regulations regarding conflict minerals and assist us in meeting our obligations under law and regulations.

We recognize these rules have required, and will continue to require, time and effort on the part of our suppliers. We appreciate their ongoing support in this important effort. If you have specific questions or would like additional information, please contact us.
