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, RGP will cease to trade on the NYSE due to its merger with Energy Transfer Partners (NYSE: ETP). 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.
CSI Compressco is a provider of compression services and equipment for natural gas and oil production, gathering, transportation, processing, and storage.
The 20 constituents of the 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.
