DALLAS, June 23, 2017 /PRNewswire/ -- Swank Capital, LLC and Cushing(®) Asset Management, LP announce a potential interim change to the constituents of The Cushing(®) 30 MLP Index (the "Index"). On February 1, 2017, Index constituents ONEOK, Inc. (NYSE: OKE) and ONEOK Partners, L.P. (NYSE: OKS) announced an Agreement and Plan of Merger wherein OKS would be acquired by OKE, subject to the approval of both OKE shareholders and OKS unitholders. Under the terms of the proposed transaction, OKE would terminate the master limited partnership ("MLP") structure of OKS and absorb it as a wholly-owned subsidiary within a C-corporation structure; consequently, OKE would cease to have an interest as a holder of general partner or limited partner units in an MLP and would, per the Methodology Guide for the Index, no longer be eligible for inclusion in the Index.

Special meetings of the OKE shareholders and OKS unitholders are scheduled for June 30, 2017, commencing at 9:00 AM Central Daylight Time for OKE shareholders and 10:00 AM Central Daylight Time for OKS unitholders for the purpose of considering and voting on the proposed transaction.

If the transaction is approved, the following changes to the Index will take place after the market closes on June 30, 2017, and be effective on July 3, 2017:
