TABLE OF CONTENTS The following graphic shows how the Board has organized oversight of ESG responsibilities to its standing committees: The primary responsibility for assisting the Board in overseeing ESG-related matters has been assigned to the Nominating and Corporate Governance Committee. The Nominating and Corporate Governance Committee, which has been helping to guide these activities, is focused on elevating the Company’s ESG performance to that of a leader amongst its peers. The Human Capital and Compensation Committee also has responsibilities related to ESG-related matters, such as ensuring the consideration of executive compensation to the achievement of ESG-related goals, employee resource group initiatives, and certifying the full and proper disclosure of our EEO-1 report. The Environmental, Health and Safety Committee exercises direct oversight over a number of ESG-related matters such as the implementation of our first greenhouse gas (“GHG”) reductions goals, the continual improvement of our workforce health and safety performance and an examination of water conservation, waste minimization, and air emission reduction efforts. The Audit Committee oversees certain ESG-related matters, such as all financial reporting disclosures related to ESG, the Company’s legal and regulatory compliance, and any potential financial risk exposure related to ESG. Each committee reports its activities to our Board, which retains overall responsibility for incorporating ESG considerations into our strategic plans.
