Supplement dated September 6, 2024

to the Funds’ Prospectus, dated March 1, 2024 (the “Prospectus”)

This supplement provides new and additional information beyond that contained in the Prospectus and should be read in conjunction with the Prospectus.

The following paragraph is hereby added to the “More Information about Fund Investments” section of the Prospectus, after the second paragraph in that section:

Each Fund is classified as a “diversified” investment company under the 1940 Act. This means that with respect to 75% of its total assets, a Fund may not purchase securities of any issuer (other than obligations of, or guaranteed by, the U.S. government or its agencies or instrumentalities, or securities of other investment companies) if, as a result, more than 5% of the Fund’s total assets would be invested in the securities of such issuer, or more than 10% of the issuer’s voting securities would be held by the Fund. Under applicable federal securities laws, the diversification of a mutual fund’s holdings is measured at the time a fund purchases a security. If a Fund holds securities that perform well on a relative basis, the value of those securities could appreciate such that the value of the Fund’s securities that constitute more than 5% of the Fund’s total assets, in the aggregate, might exceed 25% of the Fund’s total assets. In these circumstances, the Adviser might determine that it is in the best interests of a Fund’s shareholders not to reduce one or more of the Fund’s holdings in securities that constitute more than 5% of the Fund’s total assets. If the Adviser makes such a determination, a Fund’s holdings in such securities would continue to exceed 25% of the Fund’s total assets, and the Fund would not purchase any additional shares of securities that constituted more than 5% of the Fund’s total assets. The Fund would continue to qualify as a diversified fund under applicable federal securities laws. If more than 25% of a Fund’s assets were invested, in the aggregate, in securities of issuers that individually represented more than 5% of the Fund’s total assets, the Fund would be subject to the risk that its performance could be disproportionately affected by the performance of such securities.
