[1] Effective October 31, 2024, the S&P 500® Index was added as a broad measure of market performance in accordance with recent changes to regulatory disclosure requirements. The Fund uses the Russell 2000® Growth Index as an additional benchmark that reflects the market segment(s) in which the Fund invests.
[2] The Russell 2000® Growth Index replaced the S&P 500® Growth Index as the Fund's additonal benchmark on December 8, 2025 because the Investment Manager and Subadviser believe the new benchmark is more representative of the Fund's current strategies.
