FHA Federal Housing Authority. + Prerefunded to call date shown. ++ Security is a "step-up" bond where the coupon increases on predetermined future date. +++ A portion of this security has been physically segregated in connection with open futures contracts in an amount equal to $128,000. # Underlying security related to inverse floaters entered into by the Trust. ## Floating rate note obligations related to securities held. The interest rates shown reflect the rates in effect at July 31, 2007. (a) The Trust invests in Morgan Stanley Institutional Liquidity Tax-Exempt Portfolio - Institutional Class, an open end investment management company managed by the Investment Adviser. Investment advisory fees paid by the Trust are reduced by an amount equal to the advisory and administrative service fees paid by Morgan Stanley Institutional Liquidity Tax-Exempt Portfolio - Institutional Class with respect to assets invested by the Trust in Morgan Stanley Institutional Liquidity Tax-Exempt Portfolio - Institutional Class. Income distributions earned by the Trust totaled $42,044 for the period ended July 31, 2007. (b) Floating Rate Note Obligations Related to Securities Held - The Trust enters into transactions in which it transfers to Dealer Trusts ("Dealer Trusts"), fixed rate bonds in exchange for cash and residual interests in the Dealer Trusts' assets and cash flows, which are in the form of inverse floating rate investments. The Dealer Trusts fund the purchases of the fixed rate bonds by issuing floating rate notes to third parties and allowing the Trust to retain residual interest in the bonds. The Trust enters into shortfall agreements with the Dealer Trusts which commit the Trust to pay the Dealer Trusts, in certain circumstances, the difference between the liquidation value of the fixed rate bonds held by the Dealer Trusts and the liquidation value of the floating rate notes held by third parties, as well as any shortfalls in interest cash flows. The residual interests held by the Trust (inverse floating rate investments) include the right of the Trust (1) to cause the holders of the floating rate notes to tender their notes at par at the next interest rate reset date, and (2) to transfer the municipal bond from the Dealer Trusts to the Trust, thereby collapsing the Dealer Trusts. The Trust accounts for the transfer of bonds to the Dealer Trusts as secured borrowings, with the securities transferred remaining in the Trust's investment assets, and the related floating rate notes reflected as Trust liabilities. The notes issued by the Dealer Trusts have interest rates that reset weekly and the floating rate note holders have the option to tender their notes to the Dealer Trusts for redemption at par at each reset date. At July 31, 2007, Trust investments with a value of $65,404,270 are held by the Dealer Trusts and serve as collateral for the $48,260,000 in floating rate note obligations outstanding at that date. Contractual maturities of the floating rate note obligations and interest rates in effect at July 31, 2007 are presented in the "Portfolio of Investments". (c) Securities have been designated as collateral in an amount equal to $14,026,909 in connection with open futures contracts and an open swap contract. (d) The aggregate cost for federal income tax purposes is $374,352,041. The aggregate gross unrealized appreciation is $15,244,394 and the aggregate gross unrealized depreciation is $2,038,001, resulting in net unrealized appreciation of $13,206,393.
