To decrease your contribution amount, you could decrease the number of units in your CSTTM Advantage Plan (provided you maintain at least 1/10 of a unit). To initiate this change, please reach out to us at 1-877-333-7377 or email us at [email protected] The sales charges paid to date on decreased units are kept in the plan as a credit on your account, to be used to purchase additional units later. For additional details, please refer to the Prospectus.
