VettaFi LLC (the Index Provider) constructs the Index in accordance with a rules-based methodology that selects 50 companies from the VettaFi US Equity Large/Mid-Cap 1000 Index (the Parent Index). As of September 30, 2025, the Index had a market capitalization range from $12.4 billion to $480.7 billion. The actual range of market capitalization will vary over time according to changes in market capitalization of the securities in the Parent Index. The Index Provider is not affiliated with the Fund or the Adviser. The Index is designed to deliver exposure to equity securities of large-capitalization U.S. issuers within the Parent Index that have high free cash flow yields, which is a financial valuation metric that compares the free cash flow a company is expected to earn against its market value adjusted for a companys debt and cash. The ratio is calculated by taking the free cash flow divided by the enterprise value. The initial Index universe is derived from the component companies of the Parent Index, excluding financial companies and real estate investment trusts. The Index Provider screens the initial universe of companies based on their projected free cash flows and earnings. Companies with negative projected free cash flows or earnings are removed from the Index universe. The remaining companies are ranked by their free cash flow yields. A growth score is then derived from each companys growth metrics (e.g., sales trends and earnings trends) for the 75 companies with the highest free cash flow yields. The 50 companies with the highest growth scores are selected by the Index Provider for inclusion in the Index. Free Cash Flow Yields = Money the company has left over after paying its operating expenses and capital expenses Enterprise Value: Total value of a company taking into consideration both the current share price (market capitalization) and the cost to pay off debt (net debt, or debt minus cash) The Adviser believes that free cash flow is a useful measure for investors as it shows the cash a company has available after operating expenses and capital expenditures, indicating the companys financial health and efficiency. A positive free cash flow indicates a companys ability to generate sufficient revenue to maintain operations and potentially return value to shareholders. The Index employs a rules-based methodology that assigns scores to certain attributes related to free cash flows. Securities that achieve a higher score, or weighting, comprise a proportionately higher amount of the Index. The rules-based methodology assigns weightings by measuring a combination of total free cash flow and free cash flow yield (that is, the yield that the company earns on its free cash flow). Individual companies are capped at 4% of the Index. The rules-based methodology also limits the amount of companies in any one sector. That is, companies in any one sector will not exceed 45% of the Index. In addition, the allocation of companies in any single sector (or weighting) will not exceed 20% of the weighting of that sector in the Parent Index. The Index rebalances quarterly and is reconstituted quarterly. The Fund generally seeks to track the returns of the Index before fees and expenses by employing a replication strategy that seeks to hold all the stocks in the Index. The Fund also may invest up to 20% of its assets in instruments other than the securities in the Index, such as derivatives, including index futures, which the Fund may use for cash management to provide for liquidity to pay redemptions and fees (attempting to remain fully invested while maintaining liquidity). The Fund will concentrate its investments (i.e., hold more than 25% of its assets) in a particular industry or group of industries to the extent that the Index is concentrated. As of the date of this Prospectus, the Fund is not concentrated in any industry or group of industries. The degree to which certain sectors, industries, or asset classes are represented in the Index may change over time. Show less
