Municipal Bonds Risk. Municipal bonds are subject to numerous risks, including higher interest rates, economic recession, deterioration of the municipal bond market, possible downgrades and defaults of interest and/or principal.

Municipal Securities Volatility Risk. The value of the securities held by the trust may be subject to steep declines or increased volatility due to changes in performance or perception of the issuers. The markets for credit instruments, including municipal securities, have experienced periods of extreme illiquidity and volatility.

Public Health Crisis Risk. A public health crisis, and the ensuing policies enacted by governments and central banks in response, could cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects.

Operational Risk. As the use of Internet technology has become more prevalent in the course of business, the trust has become more susceptible to potential operational risks through breaches in cybersecurity.

Income distributions per unit will vary with changes in interest received on the underlying bonds and with changes in the trust's fees and expenses. Generally, as bonds in the portfolio mature or are redeemed by the issuer, income distributions per unit will decrease. Principal distributions per unit will be made only when the trust receives principal cash, generally from bonds maturing or proceeds from bond calls, and therefore will vary. With the exception of zero coupon bonds, bonds are generally callable at par value, or possibly, at a premium over par. Zero coupon bonds are generally callable at their accreted value on the call date or, possibly, at a premium over such accreted value. Both income and principal distributions may be affected by the sale of bonds in the portfolio. Refer to the prospectus for a further discussion of the factors which could affect income and principal distributions.
