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

Dallas, Texas (January 26, 2015) Swank Capital, LLC and Cushing® Asset Management, LP announce today an interim constituent change to The Cushing® MLP Market Cap Index (the “Index”). Index constituents Williams Partners L.P. (NYSE: WPZ) and Access Midstream Partners, L.P. (NYSE: ACMP) previously entered a merger agreement between the two firms wherein WPZ would become a subsidiary of ACMP (the “Merger”). Pursuant to the terms of the merger agreement, following the Merger closing after the market opens on February 2, 2015 (the “Distribution Date”), each publicly held WPZ Common Unit will be exchanged for 0.86672 ACMP Common Units, with ACMP continuing as the surviving entity following the Merger.

Following the closing of the Merger, ACMP anticipates changing its name to Williams Partners L.P. and changing the ticker symbol for ACMP Common Units to “WPZ”.

Accordingly, barring any unforeseen events, WPZ will be removed from the Index and replaced with NGL Energy Partners LP (NYSE: NGL) after the markets close on February 2, 2015. The changes will be effective on February 3, 2015.

Upon the aforementioned name change being made effective, which may be as early as February 3, 2015, the Index will reflect Williams Partners, L.P. with ticker symbol “WPZ” (changed from Access Midstream Partners, L.P. and ticker ACMP) as a constituent.

The remaining constituents of the Index will be unaffected.
