DALLAS, Nov. 30, 2015 /PRNewswire/ -- Alerian announced today that MPLX LP (NYSE: MPLX) is expected to be added to the Alerian MLP Infrastructure Index (NYSE: AMZI) replacing MarkWest Energy Partners (NYSE: MWE) in a special rebalancing.
Special rebalancings are triggered by corporate actions that result in the termination of trading of an index constituent on a major US exchange. Such corporate actions include, but are not limited to, mergers, delistings, and bankruptcies. Pending unitholder approval, MWE will cease to trade on the NYSE due to its merger with MPLX. If approved, the rebalancing will take place one full trading session after the constituent's issuance of a press release indicating all needed merger votes have passed.
MPLX owns, operates, develops, and acquires pipelines and other midstream assets related to the transportation and storage of crude oil, refined products, and other hydrocarbon-based products.
The constituents of the index will be rebalanced on a capped, float-adjusted, capitalization-weighted basis in accordance with the existing index methodology. Constituent additions to and deletions from the index do not reflect an opinion by Alerian on the investment merits of the respective securities.
