For purpose of the 80% policy, the Fund considers mid cap companies to be those whose market capitalization falls within the 12-month range of companies in the Russell Midcap Growth Index. The market capitalizations within the index will vary, but as of October 31, 2025, the market capitalization range of the Russell Midcap Growth Index was between $121 million and $108.41 billion. The Fund is actively managed and may engage in active and frequent trading of its portfolio securities. The Fund uses an active, systematic strategy designed to select mid-sized capitalization growth stocks using a proprietary quantitative methodology. The Fund seeks to generate alpha and maximize expected excess returns by utilizing a set of proprietary factors or signals based on fundamental research. Alpha is a measure of how much the Fund outperforms relative to its performance benchmark index. The Fund utilizes portfolio optimization techniques to manage risk by maintaining characteristics that are similar to those of the performance benchmark index and to evaluate security combinations and weightings in an effort to construct the portfolio given the Funds performance benchmark index and target risk objective. The Fund may concentrate its portfolio investments in any one industry or group of industries under certain circumstances. Generally, the Fund will not invest more than 25% of the value of its total assets in the securities of companies conducting their principal business activities in the same industry, except that, to the extent that an industry represents 20% or more of the Funds benchmark index at the time of investment, the Fund may invest up to 35% of its total assets in that industry. The Funds benchmark index is the Russell Midcap Growth Index. The Fund is actively-managed and, thus, does not seek to replicate the performance of a specified index. Accordingly, portfolio management has discretion on a daily basis to manage the Funds portfolio in accordance with the Funds investment objective. The Fund may seek to earn additional income through lending its securities to certain qualified broker-dealers and institutions in an amount equal to up to one-third of its total assets as determined at the time of the loan origination.
