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.

Insurance Risks. Certain of the securities in the trust are covered by insurance policies obtained by the issuers or underwriters of the bonds from insurance companies. There can be no assurance that any insurer will be able to satisfy its commitments in the event claims are made in the future.

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.

Estimated current return is determined by dividing a Trust's estimated net annual interest income per unit by the public offering price per unit. Estimated long-term return is a measure of the estimated return over the estimated life of a Trust. Unlike estimated current return, estimated long-term return reflects maturities, estimated principal prepayments, Trust charges and expenses, and discounts and premiums of securities in a Trust. Returns and prices will fluctuate. Consult a prospectus for a more complete description of the estimated current return and estimated long-term return calculations.
