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 Nuclear Energy Index by investing in a portfolio of securities that generally replicates the Nuclear Energy Index. Unlike many investment companies that try to beat the performance of a benchmark index, the Fund does not try to beat the Nuclear Energy Index and does not seek temporary defensive positions that are inconsistent with its investment objective of seeking to replicate the Nuclear Energy Index. The Fund is classified as a non-diversified fund under the Investment Company Act of 1940, as amended (the Investment Company Act of 1940), and, therefore, may invest a greater percentage of its assets in a particular issuer. The Fund may concentrate its investments in a particular industry or group of industries to the extent that the Nuclear Energy Index concentrates in an industry or group of industries. As of December 31, 2024, the energy, industrials and utilities sectors represented a significant portion of the Fund. Show less
