For our group manufacturing sites, we conduct a survey using the Self-Assessment Questionnaire, whichincludes slavery and human trafficking. Based on the survey results, we conduct on-site hearings. Theresults are fed back to each site, based on which corrective measures will be taken. For sites engaged inmining, we conduct a survey which focuses on human rights issues specific to the mining business.

We request our suppliers to understand and implement the Procurement Policy. In addition, we haveidentified suppliers which could have a significant impact on our business as “critical suppliers”. We request
the critical suppliers to submit the Supplier Self-Assessment Questionnaire (hereinafter, called “SuppliersSAQ”) and assess their conditions relating to the issues of human rights & labour (including slavery, humantrafficking, child labour, non-discrimination, harassment, and working environment), health & safety,environment, and ethics.

Effectiveness and Performance Review
In FY 2020, we conducted surveys at seven sites of the Mitsui Kinzoku Group in Japan and one site in2

Indonesia. There were no cases of slavery and human trafficking. In FY 2021, we will conduct the surveys
in three sites in Japan and three overseas. This plan may be changed or postponed due to the influence ofCOVID-19.

We have started the supply chain management from FY 2018. In FY 2020, we conducted Supplier
Assessments using the Suppliers SAQ, and 266 suppliers answered. There were no cases of slavery andhuman trafficking among these suppliers. Of the 784 companies identified as “critical suppliers”, 721
suppliers, or more than 90% of them answered to the Suppliers SAQ from FY 2018 to FY 2020. From FY
2022 onward, we plan to implement the Suppliers SAQ to 100 % of target suppliers which will be identified
every financial year.
