[1] Returns for net indices generally assume the reinvestment of dividends after the deduction of the maximum withholding tax in each country applicable to non-residents of the country as determined by the index provider. Such indices use withholding tax rates that are often at a higher rate than the rates to which the Fund is subject in each country, including for countries where the Fund is not subject to withholding taxes. When this is the case, index performance will be lower than if the index used the Fund's applicable withholding tax rates, if any.

[2] The STOXX Emerging Markets Equity Factor Index (Spliced) reflects the performance of the MSCI Emerging Markets Diversified Multiple-Factor Index (Net) through February 28, 2023 and the STOXX Emerging Markets Equity Factor Index (Net) thereafter, which reflect the times when each index was the Underlying Index of the Fund.
