[1] The Institutional Shares commenced operations on November 29, 2017, and the Institutional Plus Shares commenced operations on November 1, 2021. In the table above, the returns of the Institutional Shares for the period prior to November 29, 2017, and the returns for Institutional Plus Shares for the period prior to November 1, 2021, reflect the returns of the Fund's Investor Shares. The Institutional Shares and Institutional Plus Shares would have had similar annual returns to the Investor Shares because the shares of each class represent investments in the same portfolio securities. However, the expenses of the Institutional Shares and Institutional Plus Shares differ from those of the Investor Shares, which would affect performance. To the extent that the Investor Shares had lower expenses than a newer share class, the performance of the Investor Shares would likely have been higher than the newer share class would have realized during the same period. The performance of the Institutional Shares and Institutional Plus Shares shown in the table has not been adjusted for differences in operating expenses of the Investor Shares.
