DALLAS, Jan. 15, 2015 /PRNewswire/ -- Alerian will be announcing constituent additions to the Alerian Index Series and rebalancing schedule related to the expected Williams Partners (NYSE: WPZ) and Access Midstream Partners (NYSE: ACMP) merger before market open on January 29, 2015. 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.
Alerian equips investors to make informed decisions about Master Limited Partnerships (MLPs) and energy infrastructure. Its benchmarks, including the flagship Alerian MLP Index (AMZ), are widely used by industry executives, investment professionals, research analysts, and national media to analyze relative performance. Over $19 billion is directly tied to the Alerian Index Series through exchange-traded products, delta one notes, and separately managed accounts.
