The following paragraph is hereby
added to the "Performance Information" section in the Fund's Summary Prospectus and in the "Summary of the Fund" section of the Fund's Prospectus:
Effective March 30, 2018 (the Effective Date), the Fund
compares its performance to that of the S&P Global 1200 Information Technology Index (Net) (the New Index). Prior to this date, the Fund compared its performance to that of the S&P Global 1200 Information Technology Index (Total
Return) (the Former Index). The Fund’s investment manager believes that the New Index provides a more appropriate basis for comparing the Fund's performance.
Additionally, as of the Effective Date, the "Average Annual
Total Returns" table in the "Performance Information" section in the Fund's Summary Prospectus and in the "Summary of the Fund" section of the Fund's Prospectus is deleted in its entirety and replaced with the following:
