[1] Effective December 31, 2020 the Fund changed its benchmark from the MSCI EAFE® Index to the MSCI EAFE® Value Index because the MSCI EAFE® Value Index is considered by the adviser to be a more appropriate benchmark reflecting the type of securities in which the Fund invests.

[2] The index returns include the reinvestment of dividends and distributions net of withholding taxes, but do not reflect fees, brokerage commissions, or other expenses.
