Ladies and Gentlemen:

Pursuant to Rule 497(j) under the Securities Act of 1933, as amended (the “1933 Act”), this letter serves as certification that the form of Prospectus for Class P2 Shares of the UBS Engage for Impact Fund, a series of the Trust, that would have been filed under paragraph (c) of Rule 497 would not have differed from those contained in Post-Effective Amendment Nos. 150/151 to the Registration Statement of the Trust, which was filed with the U.S. Securities and Exchange Commission electronically via EDGAR on February 22, 2021, pursuant to Rule 485(b) under the 1933 Act.

Please direct questions or comments relating to the filing to me at the above-referenced telephone number.

Very truly yours,
