The Board of Trustees for the Fund approved a change in the Fund’s name and ticker symbol. This change is expected to become effective on or about August 24, 2026. The Fund’s name will change to “First Trust Active Factor International ETF,” and the Fund’s ticker will change to “AFDM.”
In connection with the change to the Fund’s name, the Fund will adopt a non-fundamental investment policy to invest at least 80% of its net assets (including investment borrowings) in the equity securities of international developed market companies listed and traded on U.S. and non-U.S. exchanges, and will no longer pursue its current dynamic developed international strategy. The Fund will instead seek to follow a multi-factor quantitative methodology to construct a portfolio of securities exhibiting exposure to the value, momentum, quality and low volatility factors. Additionally, the Fund’s annual unitary management fee will be reduced to 0.80% of the Fund’s average daily net assets, the Fund’s portfolio management team will change to members of the First Trust Investment Committee, and the Fund will no longer have a sub-advisor.
