Strategy. 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. Miller/Howard Investments, Inc. (the Sub-Adviser) serves as the sub-adviser for the Fund and manages the Funds investments. The Fund utilizes a bottom-up fundamental research process to evaluate 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 Funds criteria of persistent cash flow generation and have management teams with a consistent track record … Show more… 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. Miller/Howard Investments, Inc. (the Sub-Adviser) serves as the sub-adviser for the Fund and manages the Funds investments. The Fund utilizes a bottom-up fundamental research process to evaluate 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 Funds 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 Fund to be engaged in the midstream energy sector. Companies engaged in the midstream energy sector are primarily structured as 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. Midstream energy services include the provision of transportation, storage, and gathering and processing infrastructure for oil, natural gas, and other products. The Fund will typically invest in approximately twenty to twenty-five companies that are engaged in the midstream energy sector, though it is not required to do so. The Fund will select these companies for investment from, as of the date of this Prospectus, approximately forty to forty-five eligible midstream energy and MLP companies. In evaluating potential portfolio companies for investment, the Fund will consider the companys liquidity (including the companys average daily traded volume) and market capitalization (generally selecting companies with market capitalizations greater than $1.5 billion). The Fund will also consider the companys ownership, public float, and corporate structure, and the companys financial characteristics, business model, valuation, and management and board members. As part of its process to evaluate potential portfolio companies, the Fund also conducts an environmental, social and governance (ESG) risk assessment and assigns an ESG risk rating for each company reviewed. The risk assessment looks at a number of factors, including exposure to environmental risks, corporate board and management team structure , and corporate governance. The Fund may directly invest up to 25% of its total assets in equity securities of certain MLPs treated as publicly-traded partnerships. The Fund will invest more than 25% of the value of its total assets in the energy, oil, and gas industries. The Funds investments in the securities of Canadian issuers are generally expected to comprise less than 40% of the value of the Funds total assets. The Fund is non-diversified, as that term is defined in the Investment Company Act of 1940, as amended (the 1940 Act). Show less
