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. Following the close of business on August 31, 2020, an outcome period for each Fund ended. Each Fund will commence a new outcome period that will begin on September 1, 2020 and end on August 31, 2021. An investment in a Fund over the course of the outcome period will be subject to the applicable Cap set forth in the table below.
