MAKING IT POSSIBLE Before I close, I want to acknowledge that it’s our people who power our success. When we completed our annual employee survey in 2017, 95 percent said that they were willing to put in the extra effort to help NiSource meet its goals. Our execution in 2017 reflects that commitment. This team is also committed to giving back to our communities, demonstrated by the more than 12,000 hours volunteered at local nonprofits and the more than $6 million in charitable giving, including nearly $1.3 million from the NiSource Charitable Foundation. That concern for the community and utility customers extends beyond the boundaries of the NiSource service territory. This was best 14 exemplified by the team of more than 220 NIPSCO employees and contractors who headed south to Florida to help restore electricity to customers affected by Hurricane Irma. Following a solid year of performance, we’ll continue to get better at creating value for our customers and all stakeholders through improved safety, reliability, affordability and environmental performance. Thank you for your continued interest and support, and for your investment in NiSource.
