Strategy. Under normal circumstances, the Fund invests at least 80% of its net assets, plus the amount of any borrowings for investment purposes (if any), in the securities of the Underlying Index. The Fund's 80% investment policy is non-fundamental and requires 60 days prior written notice to shareholders before it can be changed. The Underlying Index, as presently constituted, is designed to track the performance of U.S. listed and domiciled companies within the S&P 500 Index that generate at least 50% of their revenues from the United States (U.S. Revenue Leaders), as determined by S&P Dow Jones Indices LLC (S&P or the "Index Provider").

The Fund's 80% investment policy is non-fundamental and requires 60 days prior written notice to shareholders before it can be changed. The Underlying Index, as presently constituted, is designed to track the performance of U.S. listed and domiciled companies within the S&P 500 Index that generate at least 50% of their revenues from the United States (U.S. Revenue Leaders), as determined by S&P Dow Jones Indices LLC (S&P or the "Index Provider"). The S&P 500 Index, which rebalances on a quarterly basis, is a float-adjusted market capitalization equity benchmark which is generally regarded as being representative of the large-capitalization segment of the U.S. stock market. A float-adjusted market capitalization weighted index weights each index component according to its market capitalization, using the number of shares that are readily available for purchase on the open market. In constructing the Underlying Index, the Index Provider utilizes FactSet, a leading financial data provider, to review the constituents of the S&P 500 Index on the basis of their geographic revenue exposure. Further, the Underlying Index will have caps in place to ensure that deviation from the sectors of the S&P 500 Index does not exceed 5% at each semi-annual rebalancing of the Underlying Index. The Underlying Index is weighted according to a modified capitalization weighting methodology and is reconstituted and re-weighted on a semi-annual basis. The modified capitalization weighting seeks to weight constituents based on their free float market capitalization subject to caps on the weights of the individual securities. Free float market capitalization measures a companys market capitalization discounted by the percentage of its shares readily available to be traded by the general public in the open market (free float). At each rebalance, the maximum weight of a company is capped at 10%. Modified capitalization weighting is expected to limit the Funds exposure to the largest market capitalization companies in the Underlying Index. As of December 31, 2025, the Underlying Index had 380 constituents. The Fund's investment objective and Underlying Index may be changed without shareholder approval. The Underlying Index is created and sponsored by the Index Provider. Any determinations related to the constituents of the Underlying Index are made by the Index Provider and are independent of the Fund's portfolio managers. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index. The Adviser uses an indexing approach to try to achieve the Fund's investment objective. Unlike many investment companies, the Fund does not try to outperform the Underlying Index and does not seek temporary defensive positions when markets decline or appear overvalued. The Fund generally will use a replication strategy. A replication strategy is an indexing strategy that involves investing in the securities of the Underlying Index in approximately the same proportions as in the Underlying Index. However, the Fund may utilize a representative sampling strategy with respect to the Underlying Index when a replication strategy might be detrimental or disadvantageous to shareholders, such as when there are practical difficulties or substantial costs involved in compiling a portfolio of equity securities to replicate the Underlying Index, in instances in which a security in the Underlying Index becomes temporarily illiquid, unavailable or less liquid, or as a result of legal restrictions or limitations (such as tax diversification requirements) that apply to the Fund but not the Underlying Index. The Adviser expects that, over time, the correlation between the Fund's performance and that of the Underlying Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation. If the Fund uses a replication strategy, it can be expected to have greater correlation to the Underlying Index than if it uses a representative sampling strategy. The Fund concentrates its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. As of December 31, 2025, the Underlying Index had significant exposure to the information technology sector. The Fund is classified as non-diversified, which means it may invest a larger percentage of its assets in a smaller number of issuers than a diversified fund. Show less
