¹ The Fund will terminate as of the close of business on 2 May, 2033, 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 2 May, 2033 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. Because the Impact Criteria and/or Nuveen's Environmental Social Governance (ESG) investment criteria may exclude investments of certain issuers for non-financial reasons, the Fund may forgo some market opportunities available to funds that do not use these criteria. This may cause the Fund to underperform the market as a whole or other funds that do not use an Impact Criteria or ESG investment strategy or that use a different methodology or different factors to determine an investment's impact and/or ESG investment criteria. Issuers of debt instruments in which the Fund may invest may default on their obligations to pay principal or interest when due. Investments of below investment grade quality are regarded as having speculative characteristics with respect to the issuer's capacity to pay interest and repay principal, and may be subject to higher price volatility and default risk than investment grade investments of comparable terms and duration. Non-U.S. investments involve risks such as currency fluctuation, political and economic instability, lack of liquidity and differing legal and accounting standards. These risks are magnified in emerging markets. The values of municipal securities held by the Fund may be adversely affected by local political and economic conditions and developments. 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. These and other risk considerations are described in more detail in the Shareholder Update section of the Fund’s annual report at nuveen.com/NPCT-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.

Responsible investing incorporates Environmental Social Governance (ESG) factors that may affect exposure to issuers, sectors, industries, limiting the type and number of investment opportunities available, which could result in excluding investment that perform well.
