"We regularly audit our supply chain through our partnership with the RBA, and in some instances, we use our own staff. Suppliers are required to perform periodic self-assessments, and many are required to undergo independent RBA audits. Specifically, those suppliers that comprise 90% of our purchases, strategic partners, and single-sourced suppliers are required to complete a biennial audit following RBA’s Validated Assessment Program through qualified third-party auditors. Suppliers must give Western Digital access to their completed self-assessment questionnaires (SAQs) and any completed RBA audit reports. We also engage with and conduct periodic audits of labor brokers and providers of on-site services such as cafeteria, janitorial cleaning, and security."
