Contractual arrangements have been made with the fund’s investment manager, Transamerica Asset Management, Inc.

These arrangements cannot be terminated prior to March 1, 2022 without the Board of Trustees’ consent. TAM is permitted to recapture amounts waived and/or reimbursed to a class during any of the 36 months from the date on which TAM waived fees and/or reimbursed expenses for the class. A class may reimburse TAM only if such reimbursement does not cause, on any particular business day of the fund, the class’s total annual operating expenses (after the reimbursement is taken into account) to exceed the applicable limits described above or any other lower limit then in effect.
