The securities in the Funds applicable benchmark index are those that are included in the Russell Midcap Index. The Russell Midcap Index measures the performance of the mid-capitalization segment of the U.S. equity universe. As of December 31, 2024, the market capitalization range for the Russell MidCap Index was approximately $351.6 million to $168.4 billion. As of December 31, 2024, the weighted average market capitalization of the Fund was approximately $28.7 billion. The Fund principally invests in common stock. The Fund will generally hold substantially all of the stocks in the index in approximately the same proportions as their weightings in the index. The sub-adviser will utilize a sampling approach to seek to replicate the performance of the Russell Midcap Index by investing in a portfolio of securities in the Russell Midcap Index that collectively has an investment profile similar to that of the Russell Midcap Index. The sampling approach may result in a small portion of the portfolio being invested in certain stocks in proportions that are not approximately the same as their index weightings, but which are expected to result in a portfolio that has, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the Funds benchmark index. The Fund will not concentrate, except to the same approximate extent as its index may concentrate, in the securities of a particular industry or group of industries (also known as a sector). The Fund will not deviate from the above noted strategies at any time for any reason. The Fund may become non-diversified, as defined under the Investment Company Act of 1940, solely as a result of a change in relative market capitalization or index weighting of one or more constituents of the index. The Fund may lend its portfolio holdings to certain financial institutions. Show less
