COMMERCIAL METALS COMPANY 2015-2016 SUSTAINABILITY REPORT 3 CMC established a commitment to keeping you up to date on our sustainability efforts in our initial Sustainability Report in 2014, and now it’s time to reinforce that commitment with our second report. We are eager to share with you all of our progress and our latest initiatives in this crucially important area for the fiscal years 2015 and 2016. With a foundation of strong ethics and values, CMC continues to organize sustainability endeavors and reporting around the key concepts of environmental stewardship, valuing our people, contributing to our communities and providing the highest levels of customer service and product responsibility. Some highlights: Safety is always our top priority, so we are pleased to report that our total recordable incident rate (TRIR) has dropped from 2.0 in 2014 to 1.5 in 2016. We believe this reduction is due, at least in part, to a number of safety initiatives we have put in place, including: • Job Instruction Training (JIT) that emphasizes a culture where employees are encouraged to do their jobs correctly, conscientiously and – above all – safely, every time. • Our Proactive Safety Measures initiative, with improved metrics that monitor and encourage proactive safety. • Increased automation of higher risk processes, including a hands- free automatic rebar bender at CMC Rebar in Gastonia, North Carolina. • Our Global Safety Management System, an online tool for tracking incidents and sharing information internally, that we’ve made easier to use. In addition to improved safety initiatives, we’ve also: • Invested in apprenticeship programs in the U.S. and Poland to attract new talent. • Continued to support worthy community causes, with $1.3 million donated to charitable organizations in 2015-2016. • Leveraged data analytics to help us optimize our energy efficiency. CMC continues to make the steel that reinforces the strength of roadways, bridges and buildings. While doing so, we also reinforce our commitment to operating our company in a sustainable, responsible, ethical way. Our greatest source of strength is our people, and every member of the CMC team deserves credit for helping the company achieve sustainability goals. All of us at CMC look forward to continuing to share our progress with you for years to come. An Introduction To the stakeholders of Commercial Metals Company – our customers, employees, communities and investors – thank you for your ongoing support. We believe operating CMC in a responsible, sustainable way is simply the right thing to do. We also believe it contributes to the success of our business.
