AMTR tracks a broad-based index of energy infrastructure MLP companies that are selected by distributions and weighted by market cap. Securities in the fund are linked to the adjusted net total return of the index. The index level reflects the notional reinvestment of the distributions from the constituent securities, subject to withholding taxes on any applicable Canadian securities. MLP investors looking to receive regular distributions should consider AMNA which tracks a variation of the same index. To be included in the underlying index, midstream energy companies must have their principal office in the US or Canada and earn the majority of their cash flow from qualifying midstream activities, such as gathering and processing, liquefaction, pipelines transportation, rail terminaling, and storage of energy commodities. The index is rebalanced quarterly. As an ETN wrapper, AMTR investors do not have any implied ownership of individual MLPs and have the credit risk of the issuer.
