Columbia Pipeline Partners LP (CPPL) (“CPPL”), a NiSource Inc. (NI) company, today provided its average distribution growth outlook through 2020.  Subject to the key assumptions described below, CPPL expects to offer unitholders an average annual distribution growth rate of approximately 20 percent.

“With approximately $8 billion in capital being deployed over the next several years at Columbia Pipeline Group, we plan to create value for CPPL unitholders through transparent and long-term distribution growth,” Robert C. Skaggs Jr., chairman and chief executive officer of CPPL said. “Most of this investment is supported by long-term, fee-based, take-or-pay contracts.”

CPPL’s minimum quarterly distribution is $0.1675 per unit, or $0.67 per unit annually. On April 29, CPPL announced its initial prorated quarterly distribution of $0.0912 per unit to both common and subordinated unitholders, which covered the portion of the first quarter 2015 between the day following the close of the initial public offering on February 11, 2015, and March 31, 2015.

CPPL’s business and operations are conducted through its 15.7 percent interest in CPG OpCo LP and its subsidiaries, which own and operate substantially all of the natural gas transmission, storage and midstream assets of NiSource Inc.’s Columbia Pipeline Group (CPG) unit.
