There is no guarantee the issuers of the securities included in the trust will declare dividends or distributions in the future. The historical distribution rate of the securities included in the trust is for illustrative purposes only and is not indicative of the trust's distribution rate. The historical distribution rate is calculated by dividing the weighted average of the trailing twelve month distributions paid by the securities included in the portfolio by the trust's offering price and is reduced to account for the effects of fees and expenses which will be incurred when investing in a trust. Certain of the issuers may have reduced their dividends or distributions over the prior twelve months. The distribution rate paid by the trust may be higher or lower than the amount shown above due to certain factors that may include, but are not limited to, a change in the dividends or distributions paid by issuers, actual expenses incurred, or the sale of securities in the portfolio.

As a result of several factors which may include changing interest rates, refundings, and sales or defaults on the underlying securities, there is no guarantee that distributions will either remain at current levels or increase over time. Estimated current return is determined by dividing a Trusts 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 net income, estimated current return and estimated long-term return calculations.
