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

Dallas, Texas (November 24, 2015) Swank Capital, LLC and Cushing® Asset Management, LP announce a potential interim change and special rebalancing of The Cushing® MLP Market Cap Index (the “Index”). Index constituent MarkWest Energy Partners, L.P. (NYSE: MWE) previously entered into an Agreement and Plan of Merger with MPLX LP (NYSE: MPLX) wherein MWE would be acquired by MPLX, subject to the approval of MWE unitholders. A special meeting of the unitholders of MWE is scheduled for December 1, 2015, at 9:00 AM Mountain Standard Time for the purpose of considering and voting on the proposed acquisition.

Should the acquisition be approved, MWE will be removed from the Index and replaced with Spectra Energy Partners, LP (NYSE: SEP) after the markets close on December 1, 2015. Additionally, because MWE is an incumbent constituent with a weighting exceeding 3.5%, all constituent weightings will be adjusted as shown below. The changes will be effective on December 2, 2015.

If the acquisition is not approved, there will be no change to the constituents of the Index or to Index constituent weightings.
