On February 23, 2026, the Trust, on behalf of each of the Funds, and U.S. Bank N.A. entered into a Securities Lending Agreement. *As a result, the following disclosure is added under the heading "Additional Investments and Risk" beginning on page 4 of the SAI:*

**LENDING OF PORTFOLIO SECURITIES.** In order to generate additional income, each of the Funds may lend portfolio securities to broker-dealers, banks or other institutional borrowers of securities. As with other extensions of credit, there may be risks of delay in recovery of the securities should the borrower of the securities fail financially. In these loan arrangements, the Funds will receive collateral in the form of cash or securities issued by or guaranteed by the U.S. Government or its agencies equal to at least 102% of the value of the securities loaned at the inception of each loan. Collateral is marked to market daily. When a Fund lends portfolio securities, it continues to be entitled to the income payable on the loaned securities by way of substitute payment and, in addition, receives securities lending income from the reinvestment of cash collateral, adjusted to reflect any fees or other payments to and from borrowers of securities.

U.S. Bank N.A. acts as securities lending agent for the Funds and receives compensation for such services, subject to compliance with conditions contained in an SEC exemptive order permitting U.S. Bank N.A. to provide such services and receive such compensation. U.S. Bank N.A. receives fees equal to a percentage of each Fund's net income from securities lending transactions. USBAM may also receive separate fees in connection with the investment of securities lending cash collateral in certain affiliated cash collateral investment vehicles managed or advised by USBAM. This may create potential conflicts of interest, including: (i) U.S. Bank N.A. as securities lending agent may have an incentive to increase or decrease the amount of securities on loan, lend particular securities, delay or forgo calling securities on loans, or lend securities to less creditworthy borrowers, in order to

------

generate additional fees for U.S. Bank N.A. and its affiliates; and (ii) U.S. Bank N.A. as securities lending agent may have an incentive to allocate loans to clients that would provide more fees to U.S. Bank N.A. To safeguard against these potential conflicts of interest, the Board of Trustees has adopted procedures designed to ensure that the fee arrangement and the other terms governing the relationship between each Fund and U.S. Bank N.A., acting as securities lending agent for the Fund, are fair.

*The entry in the table of Trustees and Officers under the heading "Management of the Trust" starting on page 58 of the SAI for "Other Directorships Held by Trustee" for Carmen A. Heredia- Lopez hereby adds the following:*

Board Member, Northwestern University Foundation (2025–Present).
