Eagle Global Advisors, LLC (the Sub-Adviser), the Funds investment sub-adviser, selects investments for the Funds portfolio from a universe of Renewable Energy Infrastructure Companies by utilizing a fundamentally-driven investment process which includes the analysis of global macro-economic and geo-political factors, fundamental company analysis, internal valuation methods, and the projected rate of return from the investment given its expected level of risk. The Sub-Adviser may sell a security when it no longer meets the criteria for inclusion in the Funds investment universe, when the security has not met or exceeded its projected rate of return or when a more attractive investment becomes available. The Fund is non-diversified and therefore may invest a larger percentage of its assets in the securities of a single issuer or smaller number of issuers than diversified funds. The Fund will concentrate ( i.e. , hold more than 25% of its total assets) in the securities of companies in the Utilities Industry Group within the Utilities Sector, as classified by the Global Industry Classification Standard. Under normal market conditions, the Fund expects to invest at least 40% of its assets in the securities of issuers that are tied economically to a number of countries throughout the world. As of March 31, 2025, the Fund had significant investment exposure to Renewable Energy Infrastructure Companies, the securities of which are issued and listed in Europe. Show less
