The investment manager has agreed to reduce its fees to reflect reduced services resulting from the Fund’s investments in Franklin Templeton affiliated funds. In addition, the transfer agency fees on Class R6 shares of the Fund have been capped so that transfer agency fees for that class do not exceed 0.03%. These contractual arrangements are expected to continue until January 31, 2027. During the terms, the fee waiver and expense reimbursement agreements may not be terminated or amended without approval of the board of trustees except to add series or classes, to reflect the extension of termination dates or to lower the waiver and expense limitation (which would result in lower fees for shareholders).
