DALLAS, Aug. 8, 2018 /PRNewswire/ -- Alerian announced today that Williams Partners (NYSE: WPZ) is expected to be removed from the Alerian Midstream Energy Index (AMNA), Alerian MLP Infrastructure Index (AMZI), Alerian US Midstream Energy Index (AMUS), Alerian MLP Index (AMZ), Alerian MLP Equal Weight Index (AMZE), Alerian Natural Gas MLP Index (ANGI), and Alerian Large Cap MLP Index (AMLI) in a special rebalancing.
