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.
