Material changes to the Fund during the period
Effective May 13, 2026, the Fund reduced its management fee from 0.20% of average daily net assets to 0.18% of daily average net assets and the Fund’s adviser has contractually agreed to waive fees and/or reimburse expenses to the extent Total Annual Fund Operating Expenses (excluding acquired fund fees and expenses other than certain money market fund fees as described below, dividend and interest expenses related to short sales, interest, taxes, expenses related to litigation and potential litigation, costs of shareholder meetings, and extraordinary expenses) exceed 0.12% of the average daily net assets of the Fund. These contractual waivers are in effect through October 31, 2027, at which time the adviser expects to charge the full management fee of 0.18% of average daily net assets.
The Fund added “Financials Sector Risk” disclosure to its summary prospectus as of November 1, 2025. This disclosure was added in light of a larger concentration of portfolio securities in this sector.
Effective June 4, 2026, the Fund changed from a diversified company to a non-diversified company and removed “Significant Holdings” risk disclosure from its prospectus and added “Non-Diversified Fund” risk disclosure to its prospectus. Since the Fund is non-diversified, it may invest a greater percentage of its assets in a particular issuer or group of issuers than a diversified fund would. This increased investment in fewer issuers may result in the Fund’s Shares being more sensitive to economic results among those issuing the securities. The value of the Fund’s Shares may also be more volatile than the value of a Fund which invests in more securities.
