Supplement dated September 22, 2022 to the
Prospectus dated May 1, 2022
This supplement provides new and additional information beyond that contained in the Prospectus and any previous supplements. It should be retained and read in conjunction with the Prospectus and any previous supplements.
Effective immediately, the following information replaces the information found in the fifth sentence of the first paragraph in the section titled Determining Net Asset Value on page 131 of the Prospectus:
A Fund will not treat an intraday disruption in NYSE trading or other event that causes an unscheduled closing of the NYSE as a close of business of the NYSE for these purposes; instead, MML Advisers will determine the fair value of a Fund’s securities in accordance with MML Advisers’ valuation procedures.
Effective immediately, the following information replaces the fourth paragraph in the section titled Determining Net Asset Value on page 132 of the Prospectus:
The Trustees have designated MML Advisers as the Funds’ “valuation designee,” responsible for determining the fair value, in good faith, of securities and other instruments held by the Funds for which market quotations are not readily available or for which such market quotations or values are considered by MML Advisers or a subadviser to be unreliable (including, for example, certain foreign securities, thinly-traded securities, certain restricted securities, certain initial public offerings, or securities whose values may have been affected by a significant event). It is possible that a significant amount of a Fund’s assets will be subject to fair valuation. The fair value determined for an investment by MML Advisers may differ from recent market prices for the investment and may be significantly different from the value realized upon the sale of such investment.
