EMLP is an actively-managed ETF which invest in MLPs, Canadian income trusts, pipeline companies, and utilities that generate at least half of their revenues from the operation of energy infrastructure assets including pipelines, storage tanks, and power transmission. MLPs have attracted significant interest for two primary reasons: (1) required quarterly distributions provide a steady stream of current income, and (2) because they are partnerships, MLPs avoid corporate income taxes at both the federal and state level; the tax liability is passed through to the individual partners. By generating at least 90% of income from natural resource-based activities such as transportation and storage, an entity can qualify as an MLP and not be taxed as a corporation. So the IRS treats shareholders of an MLP as partners, making the MLP itself a pass-through entity. That means that taxes are avoided at the corporate level, and investors avoid the double taxation of income. Investors who prefer the ETN structure as the preferred means of tapping into this asset class should consider AMJ or MLPI. Those looking to minimize expenses should take a closer look at MLPA, as this offering has by far the cheapest price tag in the MLP space.
