Item 4. Mine Safety Disclosures.

Our highest priority is the health, safety and well-being of our workforce. We believe health and safety considerations are integral to, and fundamental for, all other functions in our organization, and we understand that the health and safety of our workforce is critical to our operational efficiency and long-term success. Our global health and safety strategy, “Safe Production Matters,” is focused on fatality prevention, eliminating systemic root causes of incidents and continuous improvement through robust management systems, which are supported by leaders empowering our teams to work safely. Foundational to our Safe Production Matters strategy is our Fatal Risk Management (FRM) program. The goal of our FRM program is to achieve zero workplace fatalities by raising awareness to fatal risks and the measures necessary to mitigate them.
