The structure, investment objective, security selection process, Portfolio composition and risk considerations for each Series, as described in the referenced final Prospectus or Prospectuses, will be substantially the same as, and will not materially differ from, that of the final Prospectus for this Series. Information with respect to pricing, the number of Units, dates and summary information regarding the characteristics of securities to be deposited in this Series is not now available and will be different since each Series has a unique Portfolio. Accordingly the information contained herein with regard to the previous Series should be considered as being included for informational purposes only.

A registration statement relating to the units of this Series will be filed with the Securities and Exchange Commission but has not yet become effective. Information contained herein is subject to completion or amendment. Such Units may not be sold nor may offers to buy be accepted prior to the time the registration statement becomes effective. This Prospectus shall not constitute an offer to sell or the solicitation of an offer to buy nor shall there be any sale of the Units in any state in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state. (Incorporated herein by reference is the final prospectus for [FTP 4](https://www.sec.gov/Archives/edgar/data/2087891/000144554626002513/s487.htm) (Registration No. 333-293226) as filed April 7, 2026 which shall be used as the preliminary Prospectus for the current series of the Fund.)
