Cushing^® Asset Management and Swank Capital Announce a Constituent Change to The Cushing^® 30 MLP Index

Dallas, Texas (July 22, 2019) Cushing^® Asset Management, LP, and Swank Capital, LLC, announce an upcoming interim change to the constituents of The Cushing^® 30 MLP Index (the “Index”). On May 7, 2019, Index constituents Andeavor Logistics LP (NYSE: ANDX) and MPLX LP (NYSE: MPLX) and related entities entered into an Agreement and Plan of Merger (“Merger Agreement”) that would result in ANDX common units ceasing to be publicly traded, subject to the approval of the holders of at least a majority of the ANDX common units. On June 28, 2019, ANDX publicly announced that entities holding a majority of common units of ANDX have agreed to deliver written consents approving the Merger Agreement and, accordingly, the merger may be completed as soon as July 30, 2019. Per the Index’s methodology guide, this event will result in a constituent replacement. Accordingly, after the market closes on July 29, 2019, and effective on July 30, 2019, TC PipeLines, LP (NYSE: TCP) will replace ANDX as a constituent of the Index at ANDX’s then-current weight.

There will be no changes to the remaining constituents of the Index due to this event.
