Prospectus Supplement NT Emerging Markets Fund

Supplement dated April 1, 2022 n Prospectus dated April 1, 2022

The Board of Directors has approved an agreement and plan of reorganization, whereby the net assets of NT Emerging Markets Fund will be transferred to Emerging Markets Fund in exchange for shares of Emerging Markets Fund (the “Reorganization”). The Board, including the directors who are not deemed to be “interested persons” pursuant to Section 2(a)(19) of the Investment Company Act of 1940, as amended, considered the proposed Reorganization and determined that it is in the best interests of each fund and would not dilute the interests of either fund’s shareholders. The Reorganization does not require a shareholder vote.

The Reorganization is expected to be effective on or about April 22, 2022, as of the close of the New York Stock Exchange. NT Emerging Markets Fund’s G Class shareholders will receive shares of equal value of the corresponding class of Emerging Markets Fund in exchange for their shares of NT Emerging Markets Fund. The value of a shareholder’s account will not change as a result of the transaction.

It is expected that the Reorganization will qualify as a tax-free reorganization for federal income tax purposes and that shareholders will not recognize any gain or loss as a result of the Reorganization. Shareholders will receive a distribution of substantially all net income and/or realized gains, if any, prior to the Reorganization.

NT Emerging Markets Fund and Emerging Markets Fund have the same investment objectives, strategies and management fees.
