Supplement To the Fund's Prospectus

Dated November 12, 2025

As described in the Fund's prospectus, Fund shareholders are subject to an upside return cap that represents the maximum percentage return an investor can achieve from an investment in the Fund for a given buffer and Target Outcome Period. On November 21, 2025, the Fund's current Target Outcome Period will end, and a new Target Outcome Period will begin as of November 24, 2025. The new Target Outcome Period will end on February 20, 2026. While the actual caps and buffer will not be determined until the first day of the new Target Outcome Period, set forth below are the anticipated cap ranges and buffer for the Fund for the Target Outcome Period beginning on November 24, 2025. A supplement to the Fund's prospectus will be filed on November 24, 2025 that will include the actual cap and buffer for the new Target Outcome Period, which may be higher or lower than the anticipated cap ranges and buffer set forth below.
