The Fund is an actively managed exchange-traded fund (ETF). The Fund seeks a high level of current income and, as a secondary objective, capital appreciation, by investing in high quality midstream energy infrastructure companies that pay current distributions to shareholders. The Funds investment sub-adviser, Miller/Howard Investments, Inc. (the Sub-Adviser), utilizes a bottom-up fundamental research process to evaluate these midstream energy infrastructure companies on a number of key metrics, including income, growth of income, distribution coverage, leverage, direct-commodity price exposure, and contract quality. To be considered as potential Fund investments, such companies will typically meet the Sub-Advisers criteria of persistent cash flow generation and have management teams with a consistent track record of efficient capital allocation. The Fund will seek to achieve its investment objectives by investing, under normal market conditions, at least 80% of its net assets in equity securities of U.S. and Canadian companies of any market capitalization deemed by the Sub-Adviser to be engaged in the midstream energy sector. The midstream energy sector primarily includes publicly-traded master limited partnerships and limited liability companies taxed as partnerships (MLPs), and companies structured or who elect to be taxed as C-corporations that derive the majority of their revenue from operating or providing midstream energy services. The Sub-Adviser considers midstream energy services to be transportation, storage, and gathering & processing infrastructure that primarily collect fees for transporting customers oil, natural gas, and other products
