Notes to Schedule of Investments:
 
(a)   Principal and/or interest payments are secured by the bond insurance company listed.
 
(b)   Capital appreciation bond.
 
(c)   Underlying security related to inverse floater entered into by the Fund. See Note 1E.
 
(d)   Advance refunded; secured by an escrow fund of U.S. Government obligations or other highly rated collateral.
 
(e)   Demand security payable upon demand by the Fund at specified time intervals no greater than thirteen months. Interest rate is redetermined periodically. Rate shown is the rate in effect on July 31, 2010.
 
(f)   Security is considered a cash equivalent.
 
(g)   Security is subject to a shortfall agreement which may require the Trust to pay amounts to a counterparty in the event of 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 $955,000. However, such shortfall payment would be reduced by the proceeds from the sale of the security underlying the inverse floater.
 
(h)   Floating rate note obligations related to securities held. The interest rates shown reflect the rates in effect at July 31, 2010. At July 31, 2010, the Fund’s investments with a value of $7,046,658 are held by the Dealer Trusts and serve as collateral for the $4,415,000 in floating rate note and dealer trust obligations outstanding at that date.

Notes to Quarterly Schedule of Portfolio Holdings
July 31, 2010
(Unaudited)
NOTE 1 — Significant Accounting Policies
A.   Security Valuations — Securities, including restricted securities, are valued according to the following policy.
     Securities are fair valued using an evaluated quote provided by an independent pricing service approved by the Board of Trustees. Evaluated quotes provided by the pricing service may be determined without exclusive reliance on quoted prices and may reflect appropriate factors such as institution-size trading in similar groups of securities, yield, quality, coupon rate, maturity, type of issue, individual trading characteristics and other market data. Short-term obligations, including commercial paper, having 60 days or less to maturity are recorded at amortized cost which approximates value. Securities with a demand feature exercisable within one to seven days are valued at par. Debt securities are subject to interest rate and credit risks. In addition, all debt securities involve some risk of default with respect to interest and principal payments.
     Securities for which market quotations either are not readily available or are unreliable are valued at fair value as determined in good faith by or under the supervision of the Trust’s officers following procedures approved by the Board of Trustees. Some of the factors which may be considered in determining fair value are fundamental analytical data relating to the investment; the nature and duration of any restrictions on transferability or disposition; trading in similar securities by the same issuer or comparable companies; relevant political, economic or issuer specific news; and other relevant factors under the circumstances.
     Valuations change in response to many factors including the historical and prospective earnings of the issuer, the value of the issuer’s assets, general economic conditions, interest rates, investor perceptions and market liquidity. Because of the inherent uncertainties of valuation, the values reflected in the financial statements may materially differ from the value received upon actual sale of those investments.
B.   Securities Transactions and Investment Income – Securities transactions are accounted for on a trade date basis. Realized gains or losses on sales are computed on the basis of specific identification of the securities sold. Interest income is recorded on the accrual basis from settlement date. Dividend income is recorded on the ex-dividend date. Bond premiums and discounts are amortized and/or accreted for financial reporting purposes.
     The Fund may periodically participate in litigation related to Fund investments. As such, the Fund may receive proceeds from litigation settlements. Any proceeds received are included in the Statement of Operations as realized gain/loss for investments no longer held and as unrealized gain/loss for investments still held.
     Brokerage commissions and mark ups are considered transaction costs and are recorded as an increase to the cost basis of securities purchased and/or a reduction of proceeds on a sale of securities. Such transaction costs are included in the determination of realized and unrealized gain (loss) from investment securities reported in the Statement of Operations and the Statement of Changes in Net Assets and the realized and unrealized net gains (losses) on securities per share in the Financial Highlights. Transaction costs are included in the calculation of the Fund’s net asset value and, accordingly, they reduce the Fund’s total returns. These transaction costs are not considered operating expenses and are not reflected in net investment income reported in the Statement of Operations and Statement of Changes in Net Assets, or the net investment income per share and ratios of expenses and net investment income reported in the Financial Highlights, nor are they limited by any expense limitation arrangements between the Fund and the investment adviser.
C.   Country Determination — For the purposes of making investment selection decisions and presentation in the Schedule of Investments, the investment adviser may determine the country in which an issuer is located and/or credit risk exposure based on various factors. These factors include the laws of the country under which the issuer is organized, where the issuer maintains a principal office, the country in which the issuer derives 50% or more of its total revenues and the country that has the primary market for the issuer’s securities, as well as other criteria. Among the other criteria that may be evaluated for making this determination are the country in which the issuer maintains 50% or more of its assets, the type of security, financial guarantees and enhancements, the nature of the collateral and the sponsor organization. Country of issuer and/or credit risk exposure has been determined to be the United States of America, unless otherwise noted.

D.   Other Risks — The Fund may invest up to 20% of its net assets in lower-quality debt securities, i.e., “junk bonds”. Investments in lower-rated securities or unrated securities of comparable quality tend to be more sensitive to economic conditions than higher rated securities. Junk bonds involve a greater risk of default by the issuer because such securities are generally unsecured and are often subordinated to other creditors’ claims.
     The value of, payment of interest on, repayment of principal for and the ability of the Fund to sell a municipal security may be affected by constitutional amendments, legislative enactments, executive orders, administrative regulations, voter initiatives and the economics of the regions in which the issuers in which the Fund invests are located.
     Many municipal securities are issued to finance similar projects, especially those relating to education, health care, transportation and utilities, conditions in those sectors can affect the overall municipal securities market and the Fund.
     There is some risk that a portion or all of the interest received from certain tax-free municipal securities could become taxable as a result of determinations by the Internal Revenue Service.
E.   Floating Rate Obligations Related to Securities Held — The Fund enters into transactions in which it transfers to Special Purpose Trusts established by a Broker Dealer (“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 Fund to retain residual interest in the bonds. The Fund may enter into shortfall agreements with the Dealer Trusts which commit the Fund 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 Fund (inverse floating rate investments) include the right of the Fund (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 Fund, thereby collapsing the Dealer Trusts. The Fund accounts for the transfer of bonds to the Dealer Trusts as secured borrowings, with the securities transferred remaining in the Fund’s investment assets, and the related floating rate notes reflected as Fund liabilities under the caption “Floating rate note and dealer trust obligations” on the Statement of Assets and Liabilities. The Fund records the interest income from the fixed rate bonds under the caption “Interest” and records the expenses related to floating rate obligations and any administrative expenses of the Dealer Trusts under the caption “Interest and residual trust expenses” on the Statement of Operations. The floating rate 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.
NOTE 2 — Additional Valuation Information
Generally Accepted Accounting Principles (“GAAP”) defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date, under current market conditions. GAAP establishes a hierarchy that prioritizes the inputs to valuation methods giving the highest priority to readily available unadjusted quoted prices in an active market for identical assets (Level 1) and the lowest priority to significant unobservable inputs (Level 3) generally when market prices are not readily available or are unreliable. Based on the valuation inputs, the securities or other investments are tiered into one of three levels. Changes in valuation methods may result in transfers in or out of an investment’s assigned level:
  Level 1  —  Prices are determined using quoted prices in an active market for identical assets.
 
  Level 2  —  Prices are determined using other significant observable inputs. Observable inputs are inputs that other market participants may use in pricing a security. These may include quoted prices for similar securities, interest rates, prepayment speeds, credit risk, yield curves, loss severities, default rates, discount rates, volatilities and others.
 
  Level 3  —  Prices are determined using significant unobservable inputs. In situations where quoted prices or observable inputs are unavailable (for example, when there is little or no market activity for an investment at the end of the period), unobservable inputs may be used. Unobservable inputs reflect the Fund’s own assumptions about the factors market participants would use in determining fair value of the securities or instruments and would be based on the best available information.
               The following is a summary of the tiered valuation input levels, as of July 31, 2010. The level assigned to the securities valuations may not be an indication of the risk or liquidity associated with investing in those securities. Because of the inherent uncertainties of valuation, the values reflected in the financial statements may materially differ from the value received upon actual sale of those investments.
