(d)	Joint exemption.
(e)	Security is a “step-up” bond where the coupon increases on a predetermined future date.
(f)	Security is subject to a shortfall agreement which may require the Trust to pay amounts to a counterparty in the event of a significant decline in the market value of the security underlying the inverse floater. In case of a shortfall, the maximum potential amount of payments the Trust could ultimately be required to make under the agreement is $4,535,000. However, such shortfall payment would be reduced by the proceeds from the sale of the security underlying the inverse floater.
(g)	Current coupon rate for an inverse floating rate municipal obligation. This rate resets periodically as the auction rate on the related security changes. Position in an inverse floating rate municipal obligation has a total value of $6,268,690 which represents 3.4% of net assets.
(h)	Resale is restricted to qualified institutional investors.
(i)	The Trust invests in Morgan Stanley Institutional Liquidity Funds — Tax Exempt Portfolio — Institutional Class, an open-end management investment 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 Funds — Tax Exempt Portfolio — Institutional Class with respect to assets invested by the Trust in Morgan Stanley Institutional Liquidity Funds — Tax Exempt Portfolio — Institutional Class.
(j)	Securities have been designated as collateral in connection with inverse floating rate municipal obligations.
(k)	The aggregate cost for federal income tax purposes approximates the aggregate cost for book purposes.
(l)	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 January 31, 2010, Trust investments with a value of $61,003,089 are held by the Dealer Trusts and serve as collateral for the $35,340,000 in floating rate note obligations outstanding at that date.

Fair Valuation Measurements

Fair value is defined as the price that the Trust would receive to sell an investment or pay to transfer a liability in a timely transaction with an independent buyer in the principal market, or in the absence of a principal market the most advantageous market for the investment or liability. GAAP utilizes a three-tier hierarchy to distinguish between (1) inputs that reflect the assumptions market participants would use in pricing an asset or liability developed based on market data obtained from sources independent of the reporting entity (observable inputs) and (2) inputs that reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing an asset or liability developed based on the best information available in the circumstances (unobservable inputs) and to establish classification of fair value measurements for disclosure purposes. Various inputs are used in determining the value of the Trust’s investments. The inputs are summarized in the three broad levels listed below.

     • Level 1 — unadjusted quoted prices in active markets for identical investments

     • Level 2 — other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit
     risk, etc.)

     • Level 3 — significant unobservable inputs (including the Trust’s own assumptions in determining the fair value of investments)

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities and the determination of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to each security.

The following is the summary of the inputs used as of January 31, 2010 in valuing the Trust’s investments carried at fair value:

Valuation of Investments — (1) portfolio securities are valued by an outside independent pricing service approved by the Trustees. The pricing service uses both a computerized grid matrix of tax-exempt securities and evaluations by its staff, in each case based on information concerning market transactions and quotations from dealers which reflect the mean between the last reported bid and ask price. The portfolio securities are thus valued by reference to a combination of transactions and quotations for the same or other securities believed to be comparable in quality, coupon, maturity, type of issue, call provisions, trading characteristics and other features deemed to be relevant. The Trustees believe that timely and reliable market quotations are generally not readily available for purposes of valuing tax-exempt securities and that the valuations supplied by the pricing service are more likely to represent the fair value of such securities; (2) futures are valued at the latest sale price on the commodities exchange on which they trade unless it is determined that such price does not reflect their market value, in which case they will be valued at their fair value as determined in good faith under procedures established by and under the supervision of the Trustees; (3) interest rate swaps are marked-to-market daily based upon quotations from market makers; (4) investments in open-end mutual funds, including the Morgan Stanley Institutional Liquidity Funds, are valued at the net asset value as of the close of each business day; and (5) short-term debt securities having a maturity date of more than sixty days at time of purchase are valued on a mark-to-market basis until

sixty days prior to maturity and thereafter at amortized cost based on their value on the 61st day. Short-term debt securities having a maturity date of sixty days or less at the time of purchase are valued at amortized cost, which approximates market value.

* Morgan Stanley announced on October 19, 2009 that it has entered into a definitive agreement to sell substantially all of its retail asset management business to Invesco Ltd. (“Invesco”), a leading global investment management company. The Trustees of the Trust approved an Agreement and Plan of Reorganization (the “Plan”). Pursuant to the Plan, substantially all of the assets of the Trust would be combined with those of a newly organized mutual fund advised by an affiliate of Invesco Ltd. (the “New Trust”). Pursuant to the Plan, shareholders of the Trust would become shareholders of the New Trust, receiving shares of such New Trust equal to the value of their holdings in the Trust. The Plan is subject to the approval of the Trust’s shareholders at a special meeting of shareholders anticipated to be held during the second quarter of 2010.

Item 2. Controls and Procedures.

(a) The Trust’s principal executive officer and principal financial officer have concluded that the Trust’s disclosure controls and procedures are sufficient to ensure that information required to be disclosed by the Trust in this Form N-Q was recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms, based upon such officers’ evaluation of these controls and procedures as of a date within 90 days of the filing date of the report.

(b) There were no changes in the Trust’s internal control over financial reporting that occurred during the registrant’s fiscal quarter that has materially affected, or is reasonably likely to materially affect, the Trust’s internal control over financial reporting.

Item 3. Exhibits.

(a) A separate certification for each principal executive officer and principal financial officer of the registrant are attached hereto.
