IMPORTANT INFORMATION ABOUT THE
VOYA MULTI-MANAGER INTERNATIONAL SMALL CAP FUND

On September 12, 2019, the Voya Multi-Manger International Small Cap Fund’s (the “Fund”) Board of Trustees (the “Board”) approved the removal of Wellington Management Company, LLP (“Wellington”) as one of the Fund’s subadvisors. Currently, Acadian Asset Management LLC (“Acadian”), Victory Capital Management Inc. (“Victory Capital”) and Wellington each manage a portion of the Fund’s assets. From the close of business November 1, 2019, through the close of business on November 15, 2019, the Fund will be in a “transition period” during which time the Fund’s assets currently managed by Wellington will be equally allocated between Acadian and Victory Capital. During this time, the Fund may not be pursuing its investment objective and strategies, and limitations on permissible investments and investment restrictions will not apply.

Accordingly, effective on or about November 15, 2019, all references in your contract prospectus and contract prospectus summary, as applicable, to “Acadian Asset Management LLC, Victory Capital Management Inc., and Wellington Management Company LLP” as subadvisers to the Fund are to be deleted and replaced with “Acadian Asset Management LLC and Victory Capital Management Inc.”
