DALLAS, Jan. 29, 2015 /PRNewswire/ -- Alerian announced that following the close of business on Monday, February 2, Williams Partners (NYSE: WPZ) will be removed from the Alerian MLP Infrastructure Index (NYSE: AMZI) in a special rebalancing.
Per Alerian's index methodology guides, special rebalancings are implemented as practically as possible on a case-by-case basis. 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. The merger between Williams Partners (NYSE: WPZ) and Access Midstream Partners (NYSE: ACMP) has been approved.
Notably, following the closing of the merger, it is anticipated that Access Midstream Partners will change its name to Williams Partners and that ACMP common units will trade on the NYSE under the ticker symbol "WPZ".
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.
