COVID-19 Economic Impact Risk. The ongoing effects of the COVID-19 global pandemic, or the potential impacts of any future public health crisis, may cause significant volatility and uncertainty in global financial markets. While vaccines have been developed, there is no guarantee that vaccines will be effective against future variants of the disease.

Current Mortgage Backed Risk. Certain of the closed-end funds included in the portfolio invest in mortgage-backed securities. Rising interest rates tend to extend the duration of mortgage-backed securities, making them more sensitive to changes in interest rates, and may reduce the market value of the securities. In addition, mortgage-backed securities are subject to prepayment risk, the risk that borrowers may pay off their mortgages sooner than expected, particularly when interest rates decline.

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.

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.
