¹ The Fund will terminate as of the close of business on 1 February, 2034, provided that the Fund’s Board of Trustees may, in its sole discretion and without any action by the shareholders of the Fund, by vote of a majority of the then Board of Trustees with notice to the shareholders, extend the Fund’s term for up to two one year periods. In addition, the Board may determine to cause the Fund to conduct an Eligible Tender Offer. If the Eligible Tender Offer is completed, the Board of Trustees may, in its sole discretion and without any action by the shareholders of the Fund, by vote of a majority of the then Board of Trustees, provide that the Fund may continue without limitation of time subject to certain terms and conditions. If an Eligible Tender Offer is not conducted, the Fund will cease investment operations, retire or redeem its leverage facilities, liquidate its investment portfolio (to the extent possible) and distribute all of its liquidated net assets to Common Shareholders of record in one or more distributions on or after 1 February, 2034 or as extended by the Board.

Important information on risk

Investing in closed-end funds involves risk; principal loss is possible. There is no guarantee the Fund's investment objectives will be achieved. Closed-end fund shares may frequently trade at a discount or premium to their net asset value. Preferred securities are subordinated to bonds and other debt instruments in a company's capital structure, and therefore are subject to greater credit risk. Debt or fixed income securities such as those held by the Fund, are subject to market risk, credit risk, interest rate risk, derivatives risk, liquidity risk, and income risk. As interest rates rise, bond prices fall. Lower credit debt securities may be more likely to fail to make timely interest or principal payments. Leverage increases return volatility and magnifies the Fund's potential return and its risks; there is no guarantee a fund's leverage strategy will be successful. Certain types of preferred, hybrid or debt securities with special loss absorption provisions, such as contingent capital securities (CoCos), may be or become so subordinated that they present risks equivalent to, or in some cases even greater than, the same company's common stock. These loss absorption features work to the benefit of the security issuer, not the investor (this fund). These and other risk considerations, including the Fund's limited term and concentration risk, are described in more detail in the Shareholder Update section of the Fund's annual report at nuveen.com/NPFD-annual-report.

An investment in this fund presents a number of risks and is not suitable for all investors. Investors should carefully review and consider potential risks before investing.
