Each Fund’s Underlying Index is an optimized index designed to reflect the performance of certain companies or securities, as applicable, that exhibit positive ESG characteristics, as well as maintain similar risk and return characteristics to the Parent Index. Effective with the rebalance at the end of May 2025, the Index Provider for each Fund has updated the index methodology for each Fund’s Underlying Index to require that the Underlying Index have a minimum ESG score of at least 10% better than that of the Parent Index, as determined by the Index Provider, which is applied at each review. Capitalized terms have the meanings ascribed to them in each Fund’s Prospectus and SAI.
