WOO Retired President & CEO, Catholic Relief Services Partnering again with industry peers, NiSource supported a targeted solution in the Tax Cuts and Jobs Act, which lowers costs for customers and supports continued customer-focused system modernization investments. And while it may affect some of NiSource’s financing plans as a result of lower cash flow, the Board of Directors and management remain confident in NiSource’s financial commitments, including its ability to retain investment grade credit. Last year, we also welcomed a new member to the Board – Eric Butler. A former executive officer with Union Pacific Corporation, Eric has extensive business experience, including leadership roles in strategic and financial planning, marketing, purchasing and corporate governance. His skills and perspective will be valuable as we continue to execute on our robust long-term utility infrastructure investment plans. At our January 2018 meeting, the Board voted to add the position of nonexecutive Vice Chairman to assist in leading our talented and dedicated Board. Kevin Kabat, NiSource board member since 2015 and retired CEO of Fifth Third Bancorp, was appointed to this role. The entire Board remains fully engaged with Joe Hamrock and the leadership team as NiSource works to create continued value for all stakeholders.
