A key element of our sustainability efforts is helping customers and suppliers adopt more sustainable practices. We set procurement guidelines to advise supply chain management decisions. In addition to new sustainable supplying principles, practices and contract clauses launched in 2015, we have plans and policies that focus on maintaining strong, trusted relationships with internal business partners. As we build deeper collaboration and engagement on programs, these partnerships strengthen our relationships in key business areas, bolstering our commitment to financial stability by balancing revenue growth initiatives, cost controls and investments in the future.
