Strategy. Under normal circumstances, the Fund invests at least 80% of its net assets (plus the amount of any borrowings for investment purposes) in income-producing master limited partnership (MLP) investments of issuers that are engaged in the transportation, storage, processing, refining, marketing, exploration, production, and mining of minerals and natural resources and in derivatives and other instruments that have economic characteristics similar to such securities.

The Fund seeks to achieve its investment objective by normally investing substantially all of its net assets in the equity securities of MLP investments. The Funds MLP investments may include the following: MLPs structured as limited partnerships (LPs) or limited liability companies (LLCs); MLPs that are taxed as C corporations; businesses that operate and have the economic characteristics of MLPs but are organized and taxed as C corporations; and securities issued by MLP affiliates. The Fund invests in MLP investments that primarily derive their revenue from businesses engaged in the gathering, processing, transporting, terminalling, storing, distributing, or marketing of natural gas, natural gas liquids, crude oil, refined products (including non-hydrocarbon based products) or other hydrocarbons (Midstream MLP investments). While the Fund primarily invests in Midstream MLP investments, it also may invest in MLP investments that primarily derive their revenue from businesses engaging in or supporting the acquisition, exploration and development, or extraction of crude oil, condensate, natural gas, natural gas liquids, or other hydrocarbons (Upstream MLP investments) and businesses engaging in the processing, treating, or refining of crude oil, natural gas liquids or other hydrocarbons (Downstream MLP investments). The Fund may invest in MLP investments of all market capitalization ranges. The Fund is non-diversified, which means that it may invest in a limited number of issuers. Under normal circumstances, the Fund typically targets higher-yielding MLP investments. The Fund concentrates its investments in the instruments of the group of industries that comprise the energy sector. The Adviser relies on its disciplined investment process in determining investment selection and weightings. To determine whether an investment should be selected for the Funds portfolio, the Adviser performs a detailed fundamental analysis of the underlying businesses owned and operated by potential MLP and energy infrastructure portfolio companies. The Adviser seeks to invest in MLP and energy infrastructure companies that it believes have, among other characteristics, sound business fundamentals, a strong record of cash flow growth, distribution continuity, a solid business strategy, and a respected management team, as well as MLP and energy infrastructure companies that are not overly exposed to changes in commodity prices. The Adviser will sell investments if it determines that any of the above-mentioned characteristics have changed materially from its initial analysis, or if it determines that an investment is no longer earning a return commensurate with its risk.
