Supplement to Each Fund’s Prospectus
Dated January 2, 2026 or February 27, 2026, As Supplemented To Date
June 24, 2026
As described in detail in each Fund’s prospectus, an investment in shares of a Fund is subject to an upside return cap (the “Cap”) that represents the maximum percentage return an investor can achieve from an investment in the Fund for the Outcome Period of approximately three months. The current Outcome Period will end on June 30, 2026, and each Fund will commence a new Outcome Period that will begin on July 1, 2026 and end on September 30, 2026. Each Fund’s Cap will not be determined until the start of the new Outcome Period. At the commencement of the new Outcome Period, each Fund will file a supplement to its prospectus that will include the actual Cap for the new Outcome Period, which may be higher or lower than the estimated Cap ranges set forth below. As of June 23, 2026, the expected range of each Fund’s Cap is set forth below.
