Black Stone Minerals (NYSE: BSM) is expected to be added to the Alerian MLP Index (NYSE: AMZ) and the Alerian MLP Equal Weight Index (CME: AMZE), 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.
Black Stone Minerals owns oil and natural gas mineral interests.
The 50 constituents of the Alerian MLP Index will be rebalanced on a float-adjusted, capitalization-weighted basis in accordance with the existing index methodology. The 50 constituents of the Alerian MLP Equal Weight Index will be rebalanced on an equal-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.
