Inergy Midstream To Join The Alerian MLP Index And Alerian MLP Equal Weight Index

DALLAS, Oct. 3, 2013 /PRNewswire/ -- Alerian announced today that Inergy Midstream NRGM is expected to be added to the Alerian MLP Index AMZ and the Alerian MLP Equal Weight Index AMZE, replacing Crestwood Midstream Partners CMLP 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, CMLP will cease to trade on the NYSE due to its merger with NRGM. If approved, the rebalancing will take place one full trading session after the issuance of a press release indicating all needed merger votes have passed.

Inergy Midstream operates natural gas, NGL and crude oil storage, transportation, and logistics businesses in the United States.

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.
