INVESTMENT RETURNS, NET ASSET VALUE (NAV) AND COMMON SHARE MARKET PRICE WILL FLUCTUATE AND TRUST SHARES, WHEN SOLD, MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL COST. NAV per share is determined by dividing the value of the trust's portfolio securities, cash and other assets, less all liabilities and preferred shares, by the total number of common shares outstanding. The common share market price is the price the market is willing to pay for shares of the trust at a given time. Common share market price is influenced by a range of factors, including supply and demand and market conditions. Total return assumes an investment at the beginning of the period, reinvestment of all distributions for the period in accordance with the trust's dividend reinvestment plan, and sale of all shares at the end of the period. The trust's adviser has waived or reimbursed fees and expenses from time to time, absent such waivers/reimbursements the trust's returns would have been lower. The Lehman Brothers Municipal Bond Index is a broad-based statistical composite of municipal bonds. The Index does not include any expenses, fees or sales charges, which would lower performance. The Index is unmanaged and should not be considered an investment. It is not possible to invest directly in an index. 1 Trust Report FOR THE SIX-MONTH PERIOD ENDED APRIL 30, 2008 MARKET CONDITIONS The financial markets experienced significant volatility throughout the six- month reporting period as many large banks and financial firms began writing down mortgage-related losses, and liquidity and credit availability became even more restricted. At the same time, the pace of economic growth began to slow, with gross domestic product (GDP) growth measuring an anemic 0.6 percent for the fourth quarter of 2007. As weaker economic data was released in the first quarter of 2008, fears of recession grew and consumer confidence waned, prompting investors to continue to seek out the relative safety of high-quality Treasury securities over other sectors of the fixed income market. The municipal bond market faced additional headwinds as various monoline bond insurers experienced credit rating downgrades, which caused spreads to widen, and the auction rate and variable rate markets deteriorated. As a result, the municipal market underperformed Treasuries for the overall period, with municipal bond prices reaching historically attractive levels relative to Treasury bonds in the first quarter of 2008. While yields on short-dated municipal securities declined, yields on intermediate- and long-dated securities rose, leading to the steepest yield curve in the past four years as the spread between one-year and 30-year maturities reached 343 basis points. After a record year for new municipal bond issuance in 2007, the amount of new issues coming to market in the first four months of 2008 declined by roughly nine percent versus the same period one year earlier due in part to a drop in refunding issuance. The Federal Reserve (the "Fed") took various steps to ease the liquidity crisis and boost the economy during the period. Not only did the Federal Open Market Committee reduce the target federal funds rate from 4.50 percent to 2.00 percent by the end of the period, but in an unprecedented move, the Fed granted primary Treasury dealers (mostly brokerage firms) access to its discount window and loosened its collateral requirements, extending loans of Treasury securities in exchange for lower quality, less liquid securities. Finally, in the biggest headline event, the Fed arranged and supported JPMorgan Chase's purchase of Bear Stearns, which was viewed by many as necessary to avoid serious market repercussions had the firm failed. 2 PERFORMANCE ANALYSIS The Trust's return can be calculated based upon either the market price or the net asset value (NAV) of its shares. NAV per share is determined by dividing the value of the Trust's portfolio securities, cash and other assets, less all liabilities and preferred shares, by the total number of common shares outstanding, while market price reflects the supply and demand for the shares. As a result, the two returns can differ, as they did during the reporting period. On an NAV basis, the Trust underperformed its benchmark index, the Lehman Brothers Municipal Bond Index. On a market price basis, the Trust outperformed its benchmark. TOTAL RETURN FOR THE SIX-MONTH PERIOD ENDED APRIL 30, 2008 ------------------------------------------------------------------------ LEHMAN BROTHERS BASED ON NAV BASED ON MARKET PRICE MUNICIPAL BOND INDEX -4.86% 9.75% 1.47% ------------------------------------------------------------------------ Performance data quoted represents past performance, which is no guarantee of future results, and current performance may be lower or higher than the figures shown. Investment return, net asset value and common share market price will fluctuate and Trust shares, when sold, may be worth more or less than their original cost. See Performance Summary for additional performance information and index definition. Although the municipal market rebounded in the last two months of the reporting period and outperformed Treasuries, it was an extremely difficult period overall, particularly for higher-yielding, lower-rated bonds as the flight to quality put considerable pressure on prices. The Trust maintained an allocation to non-rated bonds throughout the reporting period whereas the Lehman Brother Municipal Bond Index contains only investment-grade issues. As such, the Trust's overweight to non-rated, higher-yielding securities was a contributor to its relative underperformance. Holdings in BBB- rated bonds, particularly within the health care and tobacco sectors, also tempered returns. The Trust's yield curve positioning also hindered performance, as it was overweighted on the long end of the municipal yield curve, which underperformed the shorter end of the curve. The negative impact was amplified by holdings in longer-maturity inverse floating-rate securities*, which are highly sensitive to interest rate changes. However, these securities did serve to enhance the Trust's income and diversification during the period. Additionally, the emphasis on the long end of the curve led to a longer duration (a measure of interest-rate sensitivity) for the Trust, which we reduced somewhat through the use of a Treasury futures hedge. However, the Trust still maintained a slightly longer duration than that of the Lehman Brothers Municipal Bond Index, which detracted from performance as rates on the intermediate and long end of the curve rose. At the same time, the Treasury market rally hurt the performance of the hedge. *An inverse floating-rate security, or "inverse floater", is a variable rate security whose coupon rate changes in the opposite direction from the change in the reference rate used to calculate the coupon rate. 3 Conversely, an overweight to pre-refunded bonds was additive to performance. These are high-quality, shorter-maturity issues which benefited as short-term rates declined during the period. The Trust's holdings in higher-yielding municipal auction rate securities (ARS) with low durations were also beneficial to performance. The Trustees have approved a procedure whereby the trust may, when appropriate, repurchase its shares in the open market or in privately negotiated transactions at a price not above market value or NAV, whichever is lower at the time of purchase. This may help support the market value of the trust's shares. There is no guarantee that any sectors mentioned will continue to perform as discussed herein or that securities in such sectors will be held by the Trust in the future. 4 RATINGS ALLOCATION AS OF 4/30/08 AAA/Aaa 45.0% AA/Aa 17.1 A/A 9.9 BBB/Baa 16.0 BB/Ba 0.8 B/B 0.4 Non-Rated 10.8 TOP FIVE SECTORS AS OF 4/30/08 Hospital 24.4% General Purpose 7.7 Single-Family 7.1 Master Tobacco Settlement 6.0 Water & Sewer 5.7 SUMMARY OF INVESTMENTS BY STATE CLASSIFICATION AS OF 4/30/08 California 12.5% Florida 10.1 Illinois 9.6 Texas 8.6 New York 7.5 New Jersey 5.0 Ohio 3.8 South Carolina 3.1 Colorado 2.6 Alabama 2.4 North Carolina 2.2 Massachusetts 2.0 Virginia 1.9 Missouri 1.9 Washington 1.8 Wisconsin 1.8 Nevada 1.7 Arizona 1.7 Connecticut 1.7 Michigan 1.7 Pennsylvania 1.7 Louisiana 1.6 Iowa 1.5 Indiana 1.3 Tennessee 1.3 District of Columbia 1.2 Maryland 1.1 Kentucky 0.9 Georgia 0.8 New Hampshire 0.6 Minnesota 0.6 Guam 0.6 Kansas 0.5 Oklahoma 0.5 Alaska 0.4 (continued on next page) 5 SUMMARY OF INVESTMENTS BY STATE CLASSIFICATION AS OF 4/30/08 (continued from previous page) West Virginia 0.3 South Dakota 0.3 North Dakota 0.3 Nebraska 0.2 Arkansas 0.2 New Mexico 0.1 Wyoming 0.1 Idaho 0.1 Vermont 0.1 Utah 0.1 Puerto Rico 0.0* ----- Total Investments 100.0% * Amount is less than 0.1% Subject to change daily.

SIGNIFICANT ACCOUNTING POLICIES Van Kampen Municipal Trust (the "Trust") is registered as a diversified, closed-end management investment company under the Investment Company Act of 1940 (the "1940 Act"), as amended. The Trust's investment objective is to seek to provide a high level of current income exempt from federal income tax, consistent with preservation of capital. The Trust will invest in a portfolio consisting substantially of municipal obligations rated investment grade at the time of investment, but may invest up to 20% of its assets in unrated securities which are believed to be of comparable quality to those rated investment grade. The Trust commenced investment operations on September 27, 1991. The following is a summary of significant accounting policies consistently followed by the Trust in the preparation of its financial statements. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. A. SECURITY VALUATION Municipal bonds are valued by independent pricing services or dealers using the mean of the last reported bid and asked prices or, in the absence of market quotations, at fair value based upon yield data relating to municipal bonds with similar characteristics and general market conditions. Securities which are not valued by independent pricing services or dealers are valued at fair value using procedures established in good faith by the Board of Trustees. Futures contracts are valued at the settlement price established each day on the exchange on which they are traded. Interest rate swaps are valued using market quotations obtained from brokers. Short-term securities with remaining maturities of 60 days or less are valued at amortized cost, which approximates market value. B. SECURITY TRANSACTIONS Security transactions are recorded on a trade date basis. Realized gains and losses are determined on an identified cost basis. The Trust may purchase and sell securities on a "when-issued" or "delayed delivery" basis, with settlement to occur at a later date. The value of the security so purchased is subject to market fluctuations during this period. The Trust will segregate assets with the custodian having an aggregate value at least equal to the amount of the when-issued or delayed delivery purchase commitments until payment is made. At April 30, 2008, the Trust had $46,050,729 of when-issued or delayed delivery purchase commitments. C. INVESTMENT INCOME Interest income is recorded on an accrual basis. Bond premium is amortized and discount is accreted over the expected life of each applicable security. D. FEDERAL INCOME TAXES It is the Trust's policy to comply with the requirements of Subchapter M of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all of its taxable income to its shareholders. Therefore, no provision for federal income taxes is required. The Trust adopted the provisions of the Financial Accounting Standards Board ("FASB") Interpretation No. 48 ("FIN 48") Accounting for Uncertainty in Income Taxes on April 30, 2008. FIN 48 sets forth a minimum threshold for financial statement recognition of the benefit of a tax position taken or expected to be 39 VAN KAMPEN MUNICIPAL TRUST NOTES TO FINANCIAL STATEMENTS -- APRIL 30, 2008 (UNAUDITED) continued taken in a tax return. The implementation of FIN 48 did not result in any unrecognized tax benefits in the accompanying financial statements. If applicable, the Trust recognizes interest accrued related to unrecognized tax benefits in "Interest Expense" and penalties in "Other" expenses on the Statement of Operations. The Trust files tax returns with the U.S. Internal Revenue Service and various states. Generally, each of the tax years in the four year period ended October 31, 2007, remains subject to examination by taxing authorities. The Trust intends to utilize provisions of the federal income tax laws which allow it to carry a realized capital loss forward for eight years following the year of the loss and offset these losses against any future realized capital gains. At October 31, 2007, the Trust had an accumulated capital loss carry forward for tax purposes of $11,515,569, which will expire according to the following schedule. AMOUNT EXPIRATION $ 468,317 ............................................................ October 31, 2008 $ 929,222 ............................................................

October 31, 2015 A portion of the capital loss carry forward above was acquired due to a merger with another regulated investment company and is subject to annual limitations. At April 30, 2008, the cost and related gross unrealized appreciation and depreciation were as follows: Cost of investments for tax purposes........................ $905,191,964 ============ Gross tax unrealized appreciation........................... $ 23,278,531 Gross tax unrealized depreciation........................... (29,860,561) ------------ Net tax unrealized depreciation on investments.............. $ (6,582,030) ============ E. DISTRIBUTION OF INCOME AND GAINS The Trust declares and pays monthly dividends from net investment income to common shareholders. Net realized gains, if any, are distributed at least annually on a pro rata basis to common and preferred shareholders. Distributions from net realized gains for book purposes may include short-term capital gains and a portion of futures gains, which are included as ordinary income for tax purposes. The tax character of distributions paid during the year ended October 31, 2007 was as follows: Distributions paid from: Ordinary income........................................... $ 14,942 Tax exempt income......................................... 43,237,394 Long-term capital gain.................................... -0- ----------- $43,252,336 =========== 40 VAN KAMPEN MUNICIPAL TRUST NOTES TO FINANCIAL STATEMENTS -- APRIL 30, 2008 (UNAUDITED) continued As of October 31, 2007, the components of distributable earnings on a tax basis were as follows: Undistributed ordinary income............................... $ 2,390 Undistributed tax-exempt income............................. 2,339,650 Undistributed long-term capital gain........................ -0- Net realized gains or losses may differ for financial reporting and tax purposes primarily as a result of gains or losses recognized on securities for tax purposes but not for book purposes. F. FLOATING RATE NOTE OBLIGATIONS RELATED TO SECURITIES HELD The Trust enters into transactions in which it transfers to 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 interests 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 under the caption "Floating Rate Note Obligations" on the Statement of Assets and Liabilities. The Trust records the interest income from the fixed rate bonds under the caption "Interest" and records the expenses related to floating rate note obligations and any administrative expenses of the dealer trusts under the caption "Interest and Residual Trust Expenses" on the Trust's Statement of Operations. 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 April 30, 2008, Trust investments with a value of $212,651,296 are held by the dealer trusts and serve as collateral for the $158,638,000 in floating rate notes outstanding at that date. Contractual maturities of the floating rate notes and interest rates in effect at April 30, 2008 are presented on the Portfolio of Investments. The average floating rate notes outstanding and average annual interest and fee rate related to residual interests during the fiscal six months ended April 30, 2008 were $200,975,143 and 3.262%, respectively. 2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES Under the terms of the Trust's Investment Advisory Agreement, Van Kampen Asset Management (the "Adviser") will provide investment advice and facilities to the Trust for an annual fee payable monthly of .55% of the average daily net assets including preferred shares of the Trust. The Adviser has agreed to waive investment advisory fees equal to .10% of the average daily net assets including preferred shares of the Trust. During the six months ended 41 VAN KAMPEN MUNICIPAL TRUST NOTES TO FINANCIAL STATEMENTS -- APRIL 30, 2008 (UNAUDITED) continued April 30, 2008, the Adviser waived $445,364 of its advisory fees. The waiver is voluntary and can be discontinued at any time. For the six months ended April 30, 2008, the Trust recognized expenses of approximately $27,200 representing legal services provided by Skadden, Arps, Slate, Meagher & Flom LLP, of which a trustee of the Trust is a partner of such firm and he and his law firm provide legal services as legal counsel to the Trust. Under separate Legal Services, Accounting Services and Chief Compliance Officer (CCO) Employment agreements, the Adviser provides accounting and legal services and the CCO provides compliance services to the Trust. The costs of these services are allocated to each trust. For the six months ended April 30, 2008, the Trust recognized expenses of approximately $48,800 representing Van Kampen Investments Inc.'s or its affiliates' (collectively "Van Kampen") cost of providing accounting and legal services to the Trust, as well as the salary, benefits and related costs of the CCO and related support staff paid by Van Kampen. Services provided pursuant to the Legal Services agreement are reported as part of "Professional Fees" on the Statement of Operations. Services provided pursuant to the Accounting Services and CCO Employment agreement are reported as part of "Accounting and Administrative Expenses" on the Statement of Operations. Certain officers and trustees of the Trust are also officers and directors of Van Kampen. The Trust does not compensate its officers or trustees who are also officers of Van Kampen. The Trust provides deferred compensation and retirement plans for its trustees who are not officers of Van Kampen. Under the deferred compensation plan, trustees may elect to defer all or a portion of their compensation to a later date. Benefits under the retirement plan are payable upon retirement for a ten-year period and are based upon each trustee's years of service to the Trust. The maximum annual benefit per trustee under the plan is $2,500. 3. CAPITAL TRANSACTIONS For the six months ended April 30, 2008 and the year ended October 31, 2007, transactions in common shares were as follows: SIX MONTHS ENDED YEAR ENDED APRIL 30, 2008 OCTOBER 31, 2007 Beginning Shares........................................ 39,063,367 39,379,538 Shares Issued Through Dividend Reinvestment............. 39,941 7,320 Shares Repurchased*..................................... (209,935) (323,491) ---------- ---------- Ending Shares........................................... 38,893,373 39,063,367 ========== ========== * On February 28, 2007, the Trust commenced a share repurchase program for purposes of enhancing stockholder value and reducing the discount at which the Trust's shares trade from their net asset value. For the six months ended April 30, 2008 and the year ended October 31, 2007, the Trust repurchased 209,935 and 323,491, respectively of its shares at an average discount of 8.51% and 6.32%, respectively from net asset value per share. The Trust expects to continue to repurchase its outstanding shares at such time and in such amounts as it believes such activity will further the accomplishment of the foregoing objectives, subject to review of the Trustees. 42 VAN KAMPEN MUNICIPAL TRUST NOTES TO FINANCIAL STATEMENTS -- APRIL 30, 2008 (UNAUDITED) continued 4. INVESTMENT TRANSACTIONS During the period, the cost of purchases and proceeds from sales of investments, excluding short-term investments, were $400,459,435 and 450,032,366 respectively. 5. DERIVATIVE FINANCIAL INSTRUMENTS A derivative financial instrument in very general terms refers to a security whose value is "derived" from the value of an underlying asset, reference rate or index. In order to seek to manage the interest rate exposure of the Trust's portfolio in a changing interest rate environment, the Trust may purchase or sell financial futures contracts or engage in transactions involving interest rate swaps, caps, floors or collars. The Trust expects to enter into these transactions primarily as a hedge against anticipated interest rate or fixed-income market changes, for duration management or for risk management purposes, but may also enter into these transactions to generate additional income. All of the Trust's portfolio holdings, including derivative instruments, are marked to market each day with the change in value reflected in the unrealized appreciation/depreciation. Upon disposition, a realized gain or loss is recognized accordingly, except when taking delivery of a security underlying a futures contract. In these instances, the recognition of gain or loss is postponed until the disposal of the security underlying the futures contract. Summarized below are the specific types of derivative financial instruments used by the Trust. A. FUTURES CONTRACTS A futures contract is an agreement involving the delivery of a particular asset on a specified future date at an agreed upon price. The Trust generally invests in exchange traded futures contracts on U.S. Treasury securities and typically closes the contract prior to the delivery date. These contracts are generally used to manage the Trust's effective maturity and duration. Upon entering into futures contracts, the Trust maintains an amount of cash or liquid securities with a value equal to a percentage of the contract amount with either a futures commission merchant pursuant to the rules and regulations promulgated under the 1940 Act, as amended, or with its custodian in an account in the broker's name. This amount is known as initial margin. During the period the futures contract is open, payments are received from or made to the broker based upon changes in the value of the contract (the variation margin). The risk of loss associated with a futures contract is in excess of the variation margin reflected on the Statement of Assets and Liabilities. Transactions in futures contracts for the six months ended April 30, 2008 were as follows: CONTRACTS Outstanding at October 31, 2007............................. 832 Futures Opened.............................................. 870 Futures Closed.............................................. (1,702) ------ Outstanding at April 30, 2008............................... -0- ====== B. INTEREST RATE SWAPS The Trust may enter into forward interest rate swap transactions intended to help the Trust manage its overall interest rate sensitivity, either shorter or longer, generally to more closely align the Trust's interest rate sensitivity with that of the broader 43 VAN KAMPEN MUNICIPAL TRUST NOTES TO FINANCIAL STATEMENTS -- APRIL 30, 2008 (UNAUDITED) continued municipal market. Forward interest rate swap transactions involve the Trust's agreement with a counterparty to pay, in the future, a fixed or variable rate payment in exchange for the counterparty paying the Trust a variable or fixed rate payment, the accruals for which would begin at a specified date in the future (the "effective date"). The amount of the payment obligation is based on the notional amount of the forward swap contract and the termination date of the swap (which is akin to a bond's maturity). The value of the Trust's swap commitment would increase or decrease based primarily on the extent to which long-term interest rates for bonds having a maturity of the swap's termination date increases or decreases. The Trust may terminate a swap contract prior to the effective date, at which point a realized gain or loss is recognized. When a forward swap is terminated, it ordinarily does not involve the delivery of securities or other underlying assets or principal, but rather is settled in cash on a net basis. The Trust intends, but is not obligated, to terminate its forward swaps before the effective date. Accordingly, the risk of loss with respect to the swap counterparty on such transactions is limited to the credit risk associated with a counterparty failing to honor its commitment to pay any realized gain to the Trust upon termination. To reduce such credit risk, all counterparties are required to pledge collateral daily (based on the daily valuation of each swap) on behalf of the Trust with a value approximately equal to the amount of any unrealized gain. Reciprocally, when the Trust has an unrealized loss on a swap contract, the Trust has instructed the custodian to pledge cash or liquid securities as collateral with a value approximately equal to the amount of the unrealized loss. Collateral pledges are monitored and subsequently adjusted if and when the swap valuations fluctuate. Restricted cash for segregating purposes, if any, is shown on the Statement of Assets and Liabilities. C. INVERSE FLOATING RATE INVESTMENTS The Trust may invest a portion of its assets in inverse floating rate instruments, either through outright purchases of inverse floating rate securities or through the transfer of bonds to a dealer trust in exchange for cash and residual interests in the dealer trust. These investments are typically used by the Trust in seeking to enhance the yield of the portfolio. These instruments typically involve greater risks than a fixed rate municipal bond. In particular, these instruments are acquired through leverage or may have leverage embedded in them and therefore involve many of the risks associated with leverage. Leverage is a speculative technique that may expose the Trust to greater risk and increased costs. Leverage may cause the Trust's net asset value to be more volatile than if it had not been leveraged because leverage tends to magnify the effect of any increases or decreases in the value of the Trust's portfolio securities. The use of leverage may also cause the Trust to liquidate portfolio positions when it may not be advantageous to do so in order to satisfy its obligations with respect to inverse floating rate instruments. 6. PREFERRED SHARES The Trust has outstanding 13,000 APS. Series A, Series B, Series C and Series D each contain 3,000 shares and Series E contains 1,000 shares. Dividends are cumulative and the dividend rates are generally reset every 7 days for Series A and Series C, while Series B, Series D and Series E are generally reset every 28 days through an auction process. Beginning on February 12, 2008 and continuing through April 30, 2008, all series of preferred shares of the Trust were not successfully remarketed. As a result, the dividend rates of these preferred shares were reset to the maximum applicable rate on APS. The average rate in effect on 44 VAN KAMPEN MUNICIPAL TRUST NOTES TO FINANCIAL STATEMENTS -- APRIL 30, 2008 (UNAUDITED) continued April 30, 2008 was 2.815%. During the six months ended April 30, 2008, the rates ranged from 2.646% to 4.800%. The Trust pays annual fees equivalent to .25% of the preferred share liquidation value for the remarketing efforts associated with the preferred auctions. These fees are included as a component of "Preferred Share Maintenance" expense on the Statement of Operations. The APS are redeemable at the option of the Trust in whole or in part at the liquidation value of $25,000 per share plus accumulated and unpaid dividends. The Trust is subject to certain asset coverage tests and the APS are subject to mandatory redemption if the tests are not met. 7. INDEMNIFICATIONS The Trust enters into contracts that contain a variety of indemnifications. The Trust's maximum exposure under these arrangements is unknown. However, the Trust has not had prior claims or losses pursuant to these contracts and expects the risk of loss to be remote. 8. ACCOUNTING PRONOUNCEMENTS In September 2006, Statement of Financial Accounting Standards No. 157, Fair Value Measurements (SFAS 157), was issued and is effective for fiscal years beginning after November 15, 2007. SFAS 157 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. As of April 30, 2008 the Adviser does not believe the adoption of SFAS 157 will impact the amounts reported in the financial statements, however, additional disclosures will be required about the inputs used to develop the measurements of fair value and the effect of certain measurements reported on the Statement of Operations for a fiscal period. On March 19, 2008, Financial Accounting Standards Board released Statement of Financial Accounting Standards No. 161, Disclosures about Derivative Instruments and Hedging Activities (SFAS 161). SFAS 161 requires qualitative disclosures about objectives and strategies for using derivatives, quantitative disclosures about fair value amounts of and gains and losses on derivative instruments, and disclosures about credit-risk-related contingent features in derivative agreements. The application of SFAS 161 is required for fiscal years and interim periods beginning after November 15, 2008. At this time, management is evaluating the implications of SFAS 161 and its impact on the financial statements has not yet been determined. 9. SUBSEQUENT EVENT On June 13, 2008, the Trust announced plans for the partial redemption of its preferred shares. The Trust intends to redeem 20% of each of its Series per the table below. The Board of Trustees previously approved the use of tender option bonds as a replacement source of funding. The Depository Trust Company, the securities' holder of record, will determine how the partial series redemptions will be allocated among each participant broker-dealer account.
