The Natural Resources Index is a global index that tracks the performance of Natural Resources Companies. Natural Resources Companies are companies principally engaged in activities related to raw materials and commodities, including metals, energy sources and agricultural products, together natural resources activities. To be initially eligible for inclusion in the Natural Resources Index, a company must generate at least 50% of its revenue from natural resources activities or have mining projects with the potential to generate at least 50% of its revenue from natural resources activities when developed and must have a market capitalization of greater than $500 million. Effective on or about June 20, 2025, to be initially eligible for inclusion in the Natural Resources Index, a company must generate at least 50% of its revenue from natural resources activities or have at least 50% of their mineral resources related to natural resources and must have a market capitalization of greater than $500 million. The Index selects Natural Resources Companies from the following sub-themes: agriculture, energy, renewable energy, industrial metals, precious metals, and forest and paper products. These sub-themes are subject to change at the discretion of MarketVector Indexes GmbH (the Index Provider or MarketVector). The Index is weighted by modified market capitalization and is published by the Index Provider, an indirectly wholly owned subsidiary of the Adviser. The Index is currently reconstituted semi-annually and rebalanced quarterly. The agriculture sub-theme includes companies principally engaged in agri-chemicals, fertilizers, seeds, traits, farm and irrigation equipment, livestock, and cultivation, among other agriculture-related activities. The energy sub-theme includes companies principally engaged in non-renewable energy sources encompassing upstream, midstream, and downstream operations. The renewable energy sub-theme includes companies principally engaged in energy storage and the operational activities and generation of energy from sustainable energy sources including, but not limited to, solar, wind, hydro, geothermal, and hydrogen. The industrial metals sub-theme includes companies principally engaged in the production of metals including, but not limited to, aluminum, copper, ferrous metals, nickel, and uranium. The precious metals sub-theme includes companies that are principally engaged in the production of gold, silver, palladium, platinum, and/or diamonds. The forest and paper products sub-theme includes companies principally engaged in the production of timber, paper, and paper-based containers as well as those companies servicing the industry. As of December 31, 2024, the Index included securities of 109 companies with a market capitalization range of between approximately $3.23 billion and $472.8 billion and a weighted average market capitalization of $92.06 billion. These amounts are subject to change. The Funds 80% investment policy is non-fundamental and may be changed without shareholder approval upon 60 days prior written notice to shareholders. The Fund, using a passive or indexing investment approach, attempts to approximate the investment performance of the Natural Resources Index by investing in a portfolio of securities that generally replicates the Natural Resources Index. Unlike many investment companies that try to beat the performance of a benchmark index, the Fund does not try to beat the Natural Resources Index and does not seek temporary defensive positions that are inconsistent with its investment objective of seeking to track the Natural Resources Index. The Fund may concentrate its investments in a particular industry or group of industries to the extent that the Natural Resources Index concentrates in an industry or group of industries. As of December 31, 2024, each of the basic materials, energy and utilities sectors represented a significant portion of the Fund. The Fund may invest in foreign securities, some of which may be denominated in foreign currencies. Additionally, the Fund may invest in depositary receipts. Show less
