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 one year. The current Outcome Period will end on October 31, 2025, and each Fund will commence a new Outcome Period that will begin on November 1, 2025 and end on October 31, 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 October 24, 2025, the expected range of each Fund’s Cap is set forth below.
