Some of the clean energy companies in which the Fund invests, including companies that the Investment Adviser believes are involved in the transition to a more sustainable energy sector, may have operations that involve traditional energy facilities (including oil, gas or other hydrocarbons). The Fund will concentrate its investments in companies in the clean energy group of industries. The Fund intends to focus its investments on clean energy infrastructure companies. The Investment Adviser expects that the Funds investments will be weighted in favor of companies that pay dividends or other current distributions. The Funds investment strategy combines bottom-up company analysis with fundamental real asset research. The Investment Adviser may decide to sell a position for various reasons, including valuation and price considerations or for risk management purposes. The Investment Adviser may integrate environmental, social and governance (ESG) factors alongside traditional fundamental factors as part of its fundamental research process. No one factor or consideration is determinative in the stock selection process. The Funds investments in U.S. and non-U.S. equity securities may include common stock, preferred stock and depositary receipts. The Fund may invest without restriction as to issuer capitalization (including small- and mid-capitalization companies). A portion of the Funds securities may be denominated in foreign currencies and held outside the United States. The Fund may invest up to 25% of its total assets (measured at time of purchase) in master limited partnerships (MLPs) that are taxed as partnerships and may invest up to 20% of its Net Assets in securities of companies that are not clean energy companies. The Funds investments in other investment companies (including exchange-traded funds (ETFs)), real estate investment trusts (REITs) and other instruments are counted towards the Funds 80% investment policy to the extent they have economic characteristics similar to the investments included within that policy. The Fund may also invest in privately held companies and companies that only recently began to trade publicly. The Fund may invest in stock, warrants and other securities of special purpose acquisition companies (SPACs). THE FUND IS NON-DIVERSIFIED UNDER THE INVESTMENT COMPANY ACT OF 1940, AS AMENDED (INVESTMENT COMPANY ACT), AND MAY INVEST A LARGER PERCENTAGE OF ITS ASSETS IN FEWER ISSUERS THAN DIVERSIFIED MUTUAL FUNDS. The Investment Adviser measures the Funds performance against the Clean Energy Income Composite Index, which is comprised of two indices: Eagle Global Renewables Infrastructure Index (Total Return, USD, Unhedged) (50%) and S&P Global Clean Energy Index (Total Return, USD, Unhedged) (50%).
