  • Natural Gas Liquids

The partnership was formerly Northern Border Partners, L.P. which was formed in 1993. On May 17, 2006, Northern Border Partners (NYSE: NBP) was renamed ONEOK Partners, L.P. Trading of ONEOK Partners common units on the New York Stock Exchange under the symbol OKS was effective May 22, 2006.
