Effective March 24, 2025, the Russell 1000 Growth Index applies a capping methodology. Index constituents are capped quarterly so that no more than 22.5% of the index weight may be allocated to a single constituent, and the sum of the weights of all constituents representing more than 4.5% of the index should not exceed 45% of the total index weight. For periods prior to March 24, 2025, the index was uncapped. Lending securities to earn income for the fund.
