It is not authorized for distribution to prospective investors unless accompanied or preceded by a current Mercer Funds prospectus. The prospectus contains more complete information about the Funds’ investment objectives, risks, and expenses. Investors are reminded to read the prospectus carefully before investing. Beginning on January 1, 2021, as permitted by regulations adopted by the Securities and Exchange Commission, paper copies of the Funds’ shareholder reports will no longer be sent by mail, unless you specifically request paper copies of the reports from a Fund or from your financial intermediary, such as a broker-dealer or bank if you hold your shares through such an institution. Instead, the reports will be made available on a website, and you will be notified by mail each time a report is posted and provided with a website link to access the report. If you already elected to receive shareholder reports electronically, you will not be affected by this change and you need not take any action. You may elect to receive shareholder reports and other communications from a Fund or your financial intermediary electronically by calling 1-888-887-0619 if you hold your shares directly with the Mercer Funds, or, if you hold your shares through a financial intermediary, by contacting your financial intermediary. You may elect to receive all future reports in paper copies free of charge. You can inform the Funds or your financial intermediary that you wish to continue receiving paper copies of your shareholder reports by calling 1-888-887-0619 if you hold your shares directly with the Mercer Funds, or, if you hold your shares through a financial intermediary, by contacting your financial intermediary. Your election to receive reports in paper copies will apply to all Funds held with the Mercer Funds or through your financial intermediary, as applicable.
