Performance is shown after deduction of ongoing charges. Any entry and exit charges are excluded from the calculation.

The performance quoted represents past performance and does not guarantee future results. Investment return and principal value of an investment will fluctuate so that an investor's shares, when sold or redeemed, may be worth more or less than the original cost. Current performance may be lower or higher than the performance quoted.

The performance information for periods prior to January 25, 2018, the commencement of operations of the share class, shows the performance of the Fund’s Institutional Shares. The performance of this share class would be substantially similar to Institutional Shares because this share class and Institutional Shares invest in the same portfolio of securities and performance would only differ to the extent that this share class and Institutional Shares have different expenses. See the Fund’s prospectus for more details.
