Unless you are eligible for a waiver, you may be assessed a contingent deferred sales charge ("CDSC") of 1.00% if you redeem any of your shares within 18 months of purchase.

Shareholders with an account held directly with a Fund that holds Retail Class shares of the Fund prior to May 6, 2024 will not be subject to the sales charge or a CDSC on any future purchases or redemptions of Retail Class shares of that Fund or any other fund that is a series of the TIAA-CREF Funds or is a Nuveen Fund in their account.
