Risks To Consider

• Investing in securities involves risk and there is no guarantee of principal.
  
  Investors should consider the investment objectives, risks, charges, and expenses of the Fund/Portfolio carefully before investing. For copies of our prospectus or summary prospectus, which contain this and other information, visit us online at www.alliancebernstein.com or contact your AB representative. Please read the prospectus and/or summary prospectus carefully before investing.
  

• Below Investment Grade Securities Risk: Investments in fixed-income securities with lower ratings (a/k/a junk bonds) are subject to a higher probability that an issuer will default or fail to meet its payment obligations. These securities may be subject to greater price volatility due to such factors as specific municipal or corporate developments and negative performance of the junk bond market generally and may be more difficult to trade than other types of securities.

• Bond Risk: The Fund is subject to the same risks as the underlying bonds in the portfolio such as credit, prepayment, call and interest rate risk. As interest rates rise the value of bond prices will decline.

• Credit Risk: A bond’s credit rating reflects the issuer’s ability to make timely payments of interest or principal—the lower the rating, the higher the risk of default. If the issuer’s financial strength deteriorates, the issuer’s rating may be lowered, and the bond’s value may decline.

• Derivatives Risk: Derivatives may be more sensitive to changes in market conditions and may amplify risks.

• Duration Risk: Duration is a measure that relates the expected price volatility of a fixed-income security to changes in interest rates. The duration of a fixed-income security may be shorter than or equal to full maturity of a fixed-income security. Fixed-income securities with longer durations have more risk and will decrease in price as interest rates rise. 

• Illiquid Investment Risk: Illiquid investments risk exists when certain investments are or become difficult to purchase or sell. Difficulty in selling such investments may result in sales at disadvantageous prices affecting the value of your investment in the Fund. 

• Inflation Risk: Prices for goods and services tend to rise over time, which may erode the purchasing power of investments.

• Interest Rate Risk: As interest rates rise, bond prices fall and vice versa, long-term securities tend to rise and fall more than short-term securities.

• Leverage Risk: To the extent the Fund uses leveraging techniques, its NAV may be more volatile because leverage tends to exaggerate the effect of changes in interest rates, and any increase or decrease in the value of the Fund’s investments.

• Market Risk: The market values of the portfolio’s holdings rise and fall from day to day, so investments may lose value. 

• Municipal Market Risk: Economic conditions, political or legislative changes, public health crises, uncertainties related to the tax status of municipal securities, or the rights of investors in these securities may negatively impact the yield or value of a municipal security.

• Non-Diversification Risk: The Fund may have more risk because it is “non-diversified”, meaning that it can invest more of its assets in a smaller number of issuers. Accordingly, changes in the value of a single security may have a more significant effect, either negative or positive, on the Fund’s net asset value. 

• Tax Risk: The U.S. Government and the U.S. Congress may periodically consider changes in federal tax law that could limit or eliminate the federal tax exemption for municipal bond income, which would in effect reduce the income received by shareholders from the Fund by increasing taxes on that income.

• Variable and Floating-Rate Securities Risk: Variable and floating-rate securities pay interest at rates that are adjusted periodically, according to a specific formula. Because the interest rate is reset only periodically, changes in the interest rate on these securities may lag behind changes in the prevailing market interest rates. The value of the security may rise or fall depending on changes in interest rates between periodic resets.

• When-Issued and Forward Commitment Risks: These securities are purchased before the securities are actually issued or delivered. These securities are subject to the risk that, when delivered, they will be worth less than the agreed-upon purchase price.

• New Fund Risk: The Fund is a recently organized, giving prospective investors a limited track record on which to base their investment decision.
