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.

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.

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.

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.
