Sector Concentration Risk. A portfolio which is concentrated in an individual sector is subject to additional risks, including limited diversification.

Build America Bonds Risk. Should a Build America Bond's issuer fail to continue meeting the requirements imposed by the American Recovery and Reinvestment Act of 2009, it may not receive federal cash subsidy payments which could impair the issuer's ability to make scheduled interest payments.

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.

Education Revenue Bonds Risk. Education revenue bonds are subject to certain risks including litigation, legislation or regulations which may adversely affect the revenues or costs of issuers of bonds in the trust, a decline in the population of "college" age individuals, and the inability to cover increased operating costs.

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.

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.

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.
