Hunton & Williams LLP advised J.P. Morgan Securities LLC, Mitsubishi UFJ Securities (USA), Inc. and Scotia Capital (USA) Inc., as joint book-running managers, in connection with Columbia Pipeline Group, Inc.’s (“CPG”) inaugural issuance of $2.75 billion in aggregate principal amount of its senior unsecured notes (the “notes”) in a private placement under Rule 144A and Regulation S of the Securities Act of 1933, as amended, to eligible purchasers. The notes will initially be fully and unconditionally guaranteed on a senior unsecured basis by certain of CPG’s subsidiaries. A portion of the net proceeds from the private offering will be used to fund a special dividend to NiSource Inc., CPG’s parent company, in connection with their planned separation, which is expected to take place in mid-2015. Upon the completion of the planned separation, CPG will become a stand-alone publicly traded company, focusing on natural gas pipeline and related businesses.

Headquartered in Houston, Texas, CPG and its subsidiaries own and operate more than 15,000 miles of strategically located natural gas pipelines, integrated with one of the largest underground storage systems in North America. From the Gulf Coast to the Midwest, Mid-Atlantic and Northeast, their systems connect premium natural gas supplies with some of the nation’s strongest energy markets, serving customers in more than 16 states. Approximately 1.3 trillion cubic feet of natural gas flows through CPG pipeline and storage systems each year, providing competitively priced, clean energy for millions of homes, businesses and industries.

The Hunton & Williams LLP team included Pete O’Brien, Christina Kwon and Henry Jin.
