ONEOK Partners Declares Quarterly Distribution





TULSA, Okla. – Oct. 21, 2015 – The board of directors of the general partner of ONEOK Partners, L.P. (NYSE: OKS) today declared a quarterly cash distribution of 79 cents per unit, effective for the third quarter 2015, payable Nov. 13, 2015, to unitholders of record as of Nov. 2, 2015.





The distribution remains unchanged from the previous quarter and represents a 2 percent increase compared with the third quarter 2014.





“At ONEOK Partners, we continue to take important steps to increase fee-based earnings in all three of our business segments,” said Terry K. Spencer, president and chief executive officer of ONEOK Partners. “By focusing on projects and initiatives that decrease our commodity exposure, we expect to obtain distribution coverage of greater than 1.0 times in 2016.”





ONEOK Partners has increased its distribution by 98 percent since April 2006, when a wholly owned subsidiary of ONEOK, Inc. (NYSE: OKE) became the sole general partner.








ONEOK Partners, L.P. (pronounced ONE-OAK) (NYSE: OKS ) is one of the largest publicly traded master limited partnerships in the United States and owns one of the nation’s premier natural gas liquids (NGL) systems, connecting NGL supply in the Mid-Continent, Permian and Rocky Mountain regions with key market centers and is a leader in the gathering, processing, storage and transportation of natural gas in the U.S. Its general partner is a wholly owned subsidiary of ONEOK, Inc.
