BLACKROCK NEW YORK MUNICIPAL BOND FUND SEPTEMBER 30, 2006 3 A Discussion With Your Fund's Portfolio Manager The Fund outperformed its broad market benchmark and its Lipper category average for the fiscal year as we continued our efforts to balance yield and total return in the portfolio. Discuss the recent market environment relative to municipal bonds. Long-term bond yields rose throughout most of the past year before moving lower in August and September 2006 as bond prices, which move opposite of yields, rose. The recent improvement in bond prices came in response to the Federal Reserve Board's (the Fed) decision to refrain from raising the federal funds rate at its August 8 meeting. This left the short-term interest rate target at 5.25%. After 17 consecutive interest rate hikes since June 2004, moderating U.S. economic growth and declining inflationary expectations were cited as reasons for the Fed pause. Earlier in the period, bond yields rose steadily (and prices declined) as investors focused on solid economic growth and rising commodity prices, which reignited fears of inflation. More recently, declines in oil prices, and particularly in gasoline prices, served to ease these earlier concerns and help boost bond prices. Overall, 30-year U.S. Treasury bond yields rose 20 basis points (.20%) during the 12-month period to 4.77%, while 10-year U.S. Treasury note yields increased 30 basis points to 4.64%. On balance, the yield curve continued to flatten during the year, leading to significant underperformance in the intermediate maturity range. Meanwhile, the tax-exempt market's strong technical position provided significant price support, allowing municipal yields to decline during the past year. As measured by Municipal Market Data, yields on AAA-rated issues maturing in 30 years fell to 4.17%, while yields on AAA-rated issues maturing in 10 years declined five basis points to 3.68%. Despite the modest decline in yields, investor demand for municipal product remained strong, evidenced by significant inflows to tax-exempt mutual funds. As reported by the Investment Company Institute, for the first eight months of 2006, municipal bond funds experienced new cash flows of over $8.25 billion, nearly a 45% increase from 2005 levels. The tax-exempt market's positive technical position has been bolstered by a decline in new bond issuance. Over the past six months, approximately $192 billion in new long-term municipal bonds was underwritten, a decline of 9.8% versus the same period a year ago. Third quarter 2006 new-issue volume of $82.3 billion represented a 20% decline from third quarter 2005. Monthly issuance of $24 billion this September represented the slowest September volume in the past five years -- and a 24% decline from September 2005. Reduced refunding activity has continued to drive the declining supply trend. For the first nine months of 2006, refundings fell more than 54% relative to the same period in 2005. Despite historically low yields, few analysts project a dramatic rebound in refunding activity for the remainder of 2006. Describe conditions in the State of New York. In December, credit-rating agency Moody's upgraded New York's rating to Aa3, the state's highest rating from Moody's since 1975. Standard & Poor's and Fitch maintained ratings of AA and AA-, respectively, and all three agencies assign a stable outlook to the state's ratings. The New York economy continues to improve and revenue collections are increasing. State tax collections remain largely dependent on the performance of the financial sector, but tax receipts over the past few years have been strong. New York's 2006 fiscal year closed on March 31, and preliminary operating results indicate a $2 billion surplus and a $945 million rainy day fund. The 2006 budget had closed an estimated $4 billion deficit. The state's 2006-2007 enacted budget was finalized on April 26, 2006. The $112.5 billion budget, which kept most of Governor George Pataki's proposals intact, includes about $850 million in tax cuts and allocates much of the prior year's surplus toward out-year gaps. The budget also includes $700 million in school operating aid as part of compliance with a court order on school funding. It is unclear whether this amount, as well as additional capital grants and bonding authority to New York City, will be sufficient in meeting the court mandate. In terms of job growth in the state, July 2006 employment estimates reflect a 1% increase from July 2005 levels. New York ranks fifth-highest among all states in per capita income. Economic growth is disproportionately stronger downstate, while the upstate economy remains lackluster. How did the Fund perform during the fiscal year? For the 12-month period ended September 30, 2006, BlackRock New York Municipal Bond Fund's (formerly Merrill Lynch New York Municipal Bond Fund) Class A, Class B, Class C and Class I Shares had total returns of +5.08%, +4.56%, +4.46% and +5.19%, respectively. (Fund results shown do not reflect sales charges and would be lower if sales charges were included. Complete performance information can be 4 BLACKROCK NEW YORK MUNICIPAL BOND FUND SEPTEMBER 30, 2006 found on pages 6 and 7 of this report to shareholders.) The unmanaged Lehman Brothers Municipal Bond Index, which measures the performance of municipal bonds nationwide, returned +4.45% for the same period while the Lipper New York Municipal Debt Funds category had an average return of +4.16%. (Funds in this Lipper category invest in securities that are exempt from New York state or city taxes.) The Fund was able to provide an above-average yield and a total return exceeding that of the broader municipal market and the average of its New York municipal bond fund peers. For the most part, performance was driven by our focus on yield, which included ample exposure to lower-quality, higher-yielding credits and an emphasis on strategies geared toward maintaining a high level of income. As credit spreads tightened and lower-quality issues outperformed, we were able to pick up incremental yield while also benefiting from the price appreciation of these credits. Particular areas of outperformance included the tobacco, airline and lower-rated hospital sectors. The Fund also benefited from its exposure to bonds issued by Puerto Rico. After lagging at the end of 2005, Puerto Rico bonds performed quite well in the spring and early summer as the commonwealth began to resolve some of its fiscal woes. Detracting from performance, although not enough to derail the Fund's strong results for the year, was a decline in the high yield sector during the final three months of the period. At this time, the bond market rallied (that is, yields declined as prices rose) and the high yield sector underperformed. What changes were made to the portfolio during the period? Throughout the year, we aimed to balance our desire to maintain an attractive yield with our goal of enhancing the portfolio's total return potential. While seeking to add exposure to higher-yielding, longer-dated credits, we also sold some short-duration bonds of the high-coupon, short-call structure. This included bonds that were either prerefunded or have a call date within three years or less. These bonds are priced with a premium and, as the call date approaches, the bonds lose value at an accelerating rate. We were willing to give up some yield in order to protect the Fund's total return potential. At times when interest rates rose, we sought to engage in yield pickup swaps -- that is, booking bonds at higher yields than those we swapped out of in order to improve the distribution rate of the portfolio. Because the new bonds come at lower prices than the book prices on the bonds being sold, this strategy also allows the portfolio to book losses, which helps to protect shareholders from potential taxable gains in the future. We also looked to buy some out-of-favor coupons, primarily discount bonds and slightly longer-maturity issues, in an effort to pick up yield. In the final quarter of the fiscal year, once the Fed paused, higher-quality and liquid credits enjoyed a strong rally, outpacing the higher yield sector for a time. Municipal bond yields hit their lows for the year and outperformed Treasury issues significantly. At this time, we saw no reason to turn over the portfolio and opted to hold onto our more attractive book yield bonds. The Fund is barbelled in terms of its credit profile, consistent with our efforts to maintain a diversified portfolio. We were able to make a number of additions on both the insured and uninsured sides of the barbell, despite a 32% decline in New York new issuance over the past year. How would you characterize the Fund's position at the close of the period? Recently, amid the decline in yields and optimism about a future Fed easing, it appears the market has gotten ahead of itself. With the 30-year Treasury yield at 4.75%, 50 basis points below the federal funds rate, it seems unlikely that the strong rally can continue. This prompted us to move to a slightly more defensive posture at period-end. We do not anticipate any significant restructuring of the portfolio in the immediate future. Since spring of this year, we have focused our attention on the 25-year sector of the curve and continue to believe that the most compelling opportunities reside there, where we are able to find attractive relative yields and good call protection for the portfolio. Timothy T. Browse, CFA Vice President and Portfolio Manager October 10, 2006 - -------------------------------------------------------------------------------- Effective October 2, 2006, the Fund's Class A, Class B, Class C and Class I Shares were redesignated Investor A1, Investor B, Investor C1 and Institutional Shares, respectively. As previously communicated to shareholders, new sales charge schedules came into effect at the same time for certain of these classes. - -------------------------------------------------------------------------------- BLACKROCK NEW YORK MUNICIPAL BOND FUND SEPTEMBER 30, 2006 5 Performance Data About Fund Performance The Fund has multiple classes of shares: o Class A Shares incur a maximum initial sales charge (front-end load) of 4% and a service fee of 0.10% per year (but no distribution fee). o Class B Shares are subject to a maximum contingent deferred sales charge of 4%, declining to 0% after six years. All Class B Shares purchased prior to December 1, 2002 will maintain the four-year schedule. In addition, Class B Shares are subject to a distribution fee of 0.25% per year and a service fee of 0.25% per year. These shares automatically convert to Class A Shares after approximately ten years. (There is no initial sales charge for automatic share conversions.) o Class C Shares are subject to a distribution fee of 0.35% per year and an account maintenance fee of 0.25% per year. In addition, Class C Shares are subject to a 1% contingent deferred sales charge if redeemed within one year of purchase. o Class I Shares are not subject to any front-end sales charge. Class I Shares bear no ongoing distribution or service fees and are available only to eligible investors. None of the past results shown should be considered a representation of future performance. Current performance may be lower or higher than the performance data quoted. Refer to www.blackrock.com to obtain performance data current to the most recent month-end. Performance results do not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares. Figures shown in each of the following tables assume reinvestment of all dividends and capital gain distributions, if any, at net asset value on the payable date. Investment return and principal value of shares will fluctuate so that shares, when redeemed, may be worth more or less than their original cost. Dividends paid to each class of shares will vary because of the different levels of service, distribution and transfer agency fees applicable to each class, which are deducted from the income available to be paid to shareholders. The Fund's Investment Adviser reimbursed a portion of its fee. Without such reimbursement, the Fund's performance would have been lower.

BLACKROCK NEW YORK MUNICIPAL BOND FUND SEPTEMBER 30, 2006 7 Disclosure of Expenses Shareholders of this Fund may incur the following charges: (a) expenses related to transactions, including sales charges, redemption fees and exchange fees; and (b) operating expenses, including advisory fees, distribution fees including 12b-1 fees, and other Fund expenses. The following example (which is based on a hypothetical investment of $1,000 invested on April 1, 2006 and held through September 30, 2006) is intended to assist shareholders both in calculating expenses based on an investment in the Fund and in comparing these expenses with similar costs of investing in other mutual funds. Each of the Actual tables below provides information about actual account values and actual expenses. In order to estimate the expenses a shareholder paid during the period covered by this report, shareholders can divide their account value by $1,000 and then multiply the result by the number in the first line under the heading entitled "Expenses Paid During the Period." Each of the Hypothetical tables below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses. In order to assist shareholders in comparing the ongoing expenses of investing in this Fund and other funds, compare the 5% hypothetical example with the 5% hypothetical examples that appear in other funds' shareholder reports. The expenses shown in the tables are intended to highlight shareholders' ongoing costs only and do not reflect any transactional expenses, such as sales charges, redemption fees or exchange fees. Therefore, the second table is useful in comparing ongoing expenses only, and will not help shareholders determine the relative total expenses of owning different funds. If these transactional expenses were included, shareholder expenses would have been higher.

Significant Accounting Policies: On September 29, 2006, Merrill Lynch New York Municipal Bond Fund and Merrill Lynch Multi-State Municipal Series Trust, of which the Fund is a part of, were renamed BlackRock New York Municipal Bond Fund (the "Fund") and BlackRock Multi-State Municipal Series Trust (the "Trust"), respectively. The Fund is registered under the Investment Company Act of 1940, as amended, as a diversified, open-end management investment company. The Fund's financial statements are prepared in conformity with U.S. generally accepted accounting principles, which may require the use of management accruals and estimates. Actual results may differ from these estimates. The Fund offers multiple classes of shares. Class A Shares are sold with a front-end sales charge. Shares of Class B and Class C may be subject to a contingent deferred sales charge. Class I Shares are sold only to certain eligible investors. All classes of shares have identical voting, dividend, liquidation and other rights and the same terms and conditions, except that Class A, Class B and Class C Shares bear certain expenses related to the account maintenance of such shares, and Class B and Class C Shares also bear certain expenses related to the distribution of such shares. Each class has exclusive voting rights with respect to matters relating to its account maintenance and distribution expenditures (except that Class B shareholders may vote on certain changes to the Class A distribution plan). Effective October 2, 2006, Class A, Class B, Class C and Class I Shares were redesignated Investor A1, Investor B, Investor C1 and Institutional Shares, respectively. Investor A1, Investor B and Investor C1 will no longer be available for purchase except through dividend reinvestment in connection with existing holdings or through certain authorized qualified employee benefit plans. Income, expenses (other than expenses attributable to a specific class) and realized and unrealized gains and losses are allocated daily to each class based on its relative net assets. The following is a summary of significant accounting policies followed by the Fund. (a) Valuation of investments -- Municipal bonds are traded primarily in the over-the-counter ("OTC") markets and are valued at the last available bid price in the OTC market or on the basis of values as obtained by a pricing service. Pricing services use valuation matrixes that incorporate both dealer-supplied valuations and valuation models. The procedures of the pricing service and its valuations are reviewed by the officers of the Fund under the general direction of the Board of Trustees. Such valuations and procedures are reviewed periodically by the Board of Trustees of the Trust. Financial futures contracts and options thereon, which are traded on exchanges, are valued at their closing prices as of the close of such exchanges. Options written or purchased are valued at the last sale price in the case of exchange-traded options. In the case of options traded in the OTC market, valuation is the last asked price (options written) or the last bid price (options purchased). Swap agreements are valued by quoted fair values received daily by the Fund's pricing service. Short-term investments with a remaining maturity of 60 days or less are valued at amortized cost, which approximates market value, under which method the investment is valued at cost and any premium or discount is amortized on a straight line basis to maturity. Investments in open-end investment companies are valued at their net asset value each business day. Securities and other assets for which market quotations are not readily available are valued at fair value as determined in good faith by or under the direction of the Board of Trustees of the Trust. (b) Derivative financial instruments -- The Fund may engage in various portfolio investment strategies both to increase the return of the Fund and to hedge, or protect, its exposure to interest rate movements and movements in the securities markets. Losses may arise due to changes in the value of the contract or if the counterparty does not perform under the contract. o Financial futures contracts -- The Fund may purchase or sell financial futures contracts and options on such financial futures contracts. Financial futures contracts are contracts for delayed delivery of securities at a specific future date and at a specific price or yield. Upon entering into a contract, the Fund deposits and maintains as collateral such initial margin as required by the exchange on which the transaction is effected. Pursuant to the contract, the Fund agrees to receive from or pay to the broker an amount of cash equal to the daily fluctuation in value of the contract. Such receipts or payments are known as variation margin and are recorded by the Fund as unrealized gains or losses. When the contract is closed, the Fund records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed. o Forward interest rate swaps -- The Fund may enter into forward interest rate swaps. In a forward interest rate swap, the Fund and the counterparty agree to make periodic net payments on a specified notional contract amount, commencing on a specified future effective date, unless terminated earlier. When the agreement is closed, the Fund records a realized gain or loss in an amount equal to the value of the agreement. 18 BLACKROCK NEW YORK MUNICIPAL BOND FUND SEPTEMBER 30, 2006 Notes to Financial Statements (continued) (c) Municipal bonds held in trust -- The Fund invests in leveraged residual certificates ("TOB Residuals") issued by tender option bond trusts ("TOBs"). A TOB is established by a third party sponsor forming a special purpose entity, into which the Fund, or an agent on behalf of the Fund, transfers municipal securities. A TOB typically issues two classes of beneficial interests: short-term floating rate certificates, which are sold to third party investors, and residual certificates, which are generally issued to the Fund which made the transfer or to affiliates of the Fund. The Fund's transfer of the municipal securities to a TOB does not qualify for sale treatment under Statement of Financial Accounting Standards No. 140 "Accounting for Transfers and Servicing of Financial Assets and Extinguishments of Liabilities," therefore the municipal securities deposited into a TOB are presented in the Fund's schedule of investments and the proceeds from the transaction are reported as a liability for trust certificates of the Fund. Similarly, proceeds from residual certificates issued to affiliates, if any, from the transaction are included in the liability for trust certificates. Interest income from the underlying security is recorded by the Fund on an accrual basis. Interest expense incurred on the secured borrowing and other expenses related to remarketing, administration and trustee services to a TOB are reported as expenses of the Fund. The floating rate certificates have interest rates that generally reset weekly and their holders have the option to tender certificates to the TOB for redemption at par at each reset date. The residual interests held by the Fund include the right of the Fund (1) to cause the holders of a proportional share of the floating rate certificates to tender their certificates at par, and (2) to transfer a corresponding share of the municipal securities from the TOB to the Fund. At September 30, 2006, the aggregate value of the underlying municipal securities transferred to TOBs was $18,637,323, the related liability for trust certificates was $8,475,000 and the range of interest rates was 3.50% to 3.54%. Financial transactions executed through TOBs generally will underperform the market for fixed rate municipal bonds in a rising interest rate environment, but tend to outperform the market for fixed rate bonds when interest rates decline or remain relatively stable. Should short-term interest rates rise, the Fund's investment in TOB Residuals likely will adversely affect the Fund's investment income-net and distributions to shareholders. Fluctuations in the market value of municipal securities deposited into the TOB may adversely affect the Fund's net asset value per share. While the Fund's investment policies and restrictions expressly permit investments in inverse floating rate securities such as TOB Residuals, they generally do not allow the Fund to borrow money for purposes of making investments. The Fund's management believes that the Fund's restrictions on borrowings do not apply to the secured borrowings deemed to have occurred for accounting purposes. (d) Income taxes -- It is the Fund's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all of its taxable income to its shareholders. Therefore, no federal income tax provision is required. (e) Recent accounting pronouncement -- In July 2006, the Financial Accounting Standards Board ("FASB") issued Interpretation No. 48 ("FIN 48") entitled "Accounting for Uncertainty in Income Taxes -- an interpretation of FASB Statement No. 109." FIN 48 prescribes the minimum recognition threshold a tax position must meet in connection with accounting for uncertainties in income tax positions taken or expected to be taken by an entity including mutual funds before being measured and recognized in the financial statements. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006. The impact on the Fund's financial statements, if any, is currently being assessed. (f) Security transactions and investment income -- Security transactions are recorded on the dates the transactions are entered into (the trade dates). Realized gains and losses on security transactions are determined on the identified cost basis. Dividend income is recorded on the ex-dividend dates. Interest income is recognized on the accrual basis. The Fund amortizes all premiums and discounts on debt securities. (g) Prepaid registration fees -- Prepaid registration fees are charged to expense as the related shares are issued. (h) Dividends and distributions -- Dividends from net investment income are declared daily and paid monthly. Distributions of capital gains are recorded on the ex-dividend dates. (i) Expenses -- Certain expenses have been allocated to the individual funds in the Trust on a pro rata basis based upon the respective aggregate net asset value of each fund included in the Trust. 2. Investment Advisory Agreement and Transactions with Affiliates: The Fund has entered into an Investment Advisory Agreement with Fund Asset Management, L.P. ("FAM"). The general partner of FAM is Princeton Services, Inc. ("PSI"), an indirect, wholly owned subsidiary of Merrill Lynch & BLACKROCK NEW YORK MUNICIPAL BOND FUND SEPTEMBER 30, 2006 19 Notes to Financial Statements (continued) Co., Inc. ("ML & Co."), which is the limited partner. The Fund has entered into a Distribution Agreement and Distribution Plans with FAM Distributors, Inc. ("FAMD" or the "Distributor"), which is a wholly owned subsidiary of Merrill Lynch Group, Inc. FAM is responsible for the management of the Fund's portfolio and provides the necessary personnel, facilities, equipment and certain other services necessary to the operations of the Fund. For such services, the Fund pays a monthly fee based upon the average daily value of the Fund's net assets at the following annual rates: .55% of the Fund's average daily net assets not exceeding $500 million; .525% of average daily net assets in excess of $500 million but not exceeding $1 billion; and .50% of average daily net assets in excess of $1 billion. The Investment Adviser has agreed to waive its management fee by the amount of management fees the Fund pays to FAM indirectly through its investment in CMA New York Municipal Money Fund. For the year ended September 30, 2006, FAM reimbursed the Fund in the amount of $8,055. Pursuant to the Distribution Plans adopted by the Fund in accordance with Rule 12b-1 under the Investment Company Act of 1940, the Fund pays the Distributor an ongoing account maintenance fee ("service fee") and a distribution fee. These fees are accrued daily and paid monthly, at the annual rates based upon the average daily net assets of the shares as follows: - -------------------------------------------------------------------------------- Service Distribution Fee Fee - -------------------------------------------------------------------------------- Class A ........................................... .10% -- Class B ........................................... .25% .25% Class C ........................................... .25% .35% - -------------------------------------------------------------------------------- Pursuant to a sub-agreement with the Distributor, Merrill Lynch, Pierce, Fenner & Smith Incorporated ("MLPF&S"), an affiliate of FAM, also provides account maintenance and distribution services to the Fund. The ongoing service fee compensates the Distributor and MLPF&S for providing account maintenance services to Class A, Class B and Class C shareholders. The ongoing distribution fee compensates the Distributor and MLPF&S for providing shareholder and distribution-related services to Class B and Class C shareholders. For the year ended September 30, 2006, FAMD earned underwriting discounts and MLPF&S earned dealer concessions on the sales of the Fund's Class A and Class I Shares as follows: - -------------------------------------------------------------------------------- FAMD MLPF&S - -------------------------------------------------------------------------------- Class A ............................ $ 7,931 $52,975 Class I ............................ $ 1,621 $18,309 - -------------------------------------------------------------------------------- For the year ended September 30, 2006, MLPF&S received contingent deferred sales charges of $24,440 and $5,944 relating to transactions in Class B and Class C Shares, respectively. Financial Data Services, Inc. ("FDS"), a wholly owned subsidiary of ML & Co., is the Fund's transfer agent. For the year ended September 30, 2006, the Fund reimbursed FAM $5,528 for certain accounting services. In February 2006, ML & Co. and BlackRock, Inc. entered into an agreement to contribute ML & Co.'s investment management business, including FAM, to the investment management business of BlackRock, Inc. The transaction closed on September 29, 2006. On July 31, 2006, shareholders of the Fund approved a new Investment Advisory Agreement with BlackRock Advisors, Inc. (the "Manager"), a wholly owned subsidiary of BlackRock, Inc. BlackRock Advisors, Inc. was reorganized into BlackRock Advisors, LLC. The new advisory agreement became effective on September 29, 2006 and the investment advisory fee is unchanged. In addition, the Manager has entered into a sub-advisory agreement with BlackRock Investment Management, LLC, an affiliate, under which the Manager pays the Sub-Adviser for services it provides a fee equal to 59% of the management fee paid to the Manager. In connection with the closing, the Fund's Transfer Agent became PFPC Inc., an affiliate of the Manager. In addition, BlackRock Distributors, Inc., an affiliate of BlackRock, Inc., became an additional distributor. Prior to the closing, certain officers and/or trustees of the Fund were officers and/or directors of FAM, PSI, FDS, FAMD, and/or ML & Co. Commencing September 29, 2006, certain officers and/or trustees of the Fund are officers and/or directors of BlackRock, Inc. or its affiliates. 20 BLACKROCK NEW YORK MUNICIPAL BOND FUND SEPTEMBER 30, 2006 Notes to Financial Statements (continued) 3.

Short-Term Borrowings: The Trust, on behalf of the Fund, along with certain other funds managed by FAM and its affiliates, is a party to a $500,000,000 credit agreement with a group of lenders, which expires November 2006. The Fund may borrow under the credit agreement to fund shareholder redemptions and for other lawful purposes other than for leverage. The Fund may borrow up to the maximum amount allowable under the Fund's current prospectus and statement of additional information, subject to various other legal, regulatory or contractual limits. The Fund pays a commitment fee of .07% per annum based on the Fund's pro rata share of the unused portion of the credit agreement. Amounts borrowed under the credit agreement bear interest at a rate equal to, at each Fund's election, the federal funds rate plus .50% or a base rate as defined in the credit agreement. The Fund did not borrow under the credit agreement during the year ended September 30, 2006. 6. Distributions to Shareholders: The tax character of distributions paid during the fiscal years ended September 30, 2006 and September 30, 2005 was as follows: - -------------------------------------------------------------------------------- 9/30/2006 9/30/2005 - -------------------------------------------------------------------------------- Distributions paid from: Tax-exempt income .................... $10,684,700 $10,303,457 ------------------------------- Total distributions .................... $10,684,700 $10,303,457 =============================== As of September 30, 2006, the components of accumulated earnings on a tax basis were as follows: ============================================================================= Undistributed tax-exempt income -- net .................. $ 271,841 Undistributed long-term capital gains -- net ............ -- ------------ Total undistributed earnings -- net ..................... 271,841 Capital loss carryforward ............................... (17,135,319)* Unrealized gains -- net ................................. 18,590,129** ------------ Total accumulated earnings -- net ....................... $ 1,726,651 ============ * On September 30, 2006, the Fund had a net capital loss carryforward of $17,135,319, of which $8,200,112 expires in 2009 and $8,935,207 expires in 2013. This amount will be available to offset like amounts of any future taxable gains. ** The difference between book-basis and tax-basis net unrealized gains is attributable primarily to the tax deferral of losses on wash sales, the tax deferral of losses on straddles, the difference between book and tax amortization methods for premiums and discounts on fixed income securities, the realization for tax purposes of unrealized gains (losses) on certain futures contracts and the difference between the book and tax treatment of residual interests in tender option bond trusts. 7. Acquisition of Lebenthal New York Municipal Bond Fund: On May 1, 2006, the Fund acquired substantially all of the assets and assumed substantially all of the liabilities of Lebenthal New York Municipal Bond Fund pursuant to a plan of reorganization. The acquisition was accomplished by a tax-free exchange of 10,938,694 shares of Common Stock of Lebenthal New York Municipal Bond Fund for 7,992,857 Class A Shares of beneficial interest of the Fund. Lebenthal New York Municipal Bond Fund's net assets on that date of $87,042,207, including $6,175 of accumulated net realized losses and $3,460,794 of net unrealized appreciation were combined with those of the Fund. The aggregate net assets immediately after the acquisition amounted to $293,674,393. 8. Restatement Information: Subsequent to issuance of its September 30, 2006 financial statements, the Fund determined that the criteria for sale accounting in Statement of Financial Accounting Standards No. 140 had not been met for certain transfers of municipal bonds and that these transfers should have been accounted for as secured borrowings rather than as sales. Accordingly, the Fund has restated the statement of assets and liabilities as of September 30, 2006, the statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended. The effects of the restatement were to record the transfers of the municipal bonds as secured borrowings, to give effect to offsetting changes in realized gain -- net and in the change in unrealized appreciation/depreciation -- net on the transferred municipal securities and to give effect to recording interest on the bonds as interest income and interest on the secured borrowings as interest expense. -

The Statements of Operations for the years ended September 30, 2005, 2004, 2003 and 2002, not presented herein, have not been reissued to give effect to the restatement. However, the principal effects of the restatement would be to increase interest income and interest expense and fees by corresponding amounts each year, and, where applicable, to revise realized gain (loss) on investments - -- net, and the change in unrealized appreciation/depreciation on investments -- net, by corresponding and offsetting amounts. The Statements of Changes in Net Assets for the years ended September 30, 2004, 2003 and 2002, not presented herein, have not been reissued to give effect to the restatement, but the principal effects of a restatement, where applicable, would be to revise previously reported realized gain (loss) -- net, and change in unrealized appreciation/depreciation -- net, by corresponding and offsetting amounts. BLACKROCK NEW YORK MUNICIPAL BOND FUND SEPTEMBER 30, 2006 23 Report of Independent Registered Public Accounting Firm To the Shareholders and Board of Trustees of BlackRock Multi-State Municipal Series Trust: We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of BlackRock New York Municipal Bond Fund, one of the portfolios constituting BlackRock Multi-State Municipal Series Trust (formerly Merrill Lynch New York Municipal Bond Fund of Merrill Lynch Multi-State Municipal Series Trust) (the "Trust"), as of September 30, 2006, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Trust's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Trust is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Trust's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of September 30, 2006, by correspondence with the custodian and brokers; where replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of BlackRock New York Municipal Bond Fund of BlackRock Multi-State Municipal Series Trust as of September 30, 2006, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and its financial highlights for each of the five years in the period then ended, in conformity with U.S. generally accepted accounting principles. As discussed in Note 8, the statement of assets and liabilities, including the schedule of investments, as of September 30, 2006, the statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended have been restated. Deloitte & Touche LLP Princeton, New Jersey November 21, 2006 (January 26, 2007 as to Note 8) Important Tax Information (unaudited) All of the net investment income distributions paid monthly by BlackRock New York Municipal Bond Fund of BlackRock Multi-State Municipal Series Trust during the taxable year ended September 30, 2006 qualify as tax-exempt interest dividends for federal income tax purposes. 24 BLACKROCK NEW YORK MUNICIPAL BOND FUND SEPTEMBER 30, 2006 Disclosure of New Investment Advisory Agreement New BlackRock Investment Advisory Agreement -- Matters Considered by the Board In connection with the combination of Merrill Lynch's investment advisory business, including Fund Asset Management, L.P. (the "Previous Investment Adviser"), with that of BlackRock, Inc. ("BlackRock") to create a new independent company ("New BlackRock") (the "Transaction"), the Fund's Board of Trustees considered and approved a new investment advisory agreement (the "BlackRock Investment Advisory Agreement") between the Fund and BlackRock Advisors, LLC ("BlackRock Advisors"). The Fund's shareholders subsequently approved the BlackRock Investment Advisory Agreement and it became effective on September 29, 2006, replacing the investment advisory agreement with the Previous Investment Adviser (the "Previous Investment Advisory Agreement"). The Board discussed the BlackRock Investment Advisory Agreement at telephonic and in-person meetings held during April and May 2006. The Board, including the independent trustees, approved the BlackRock Investment Advisory Agreement at an in-person meeting held on May 9, 2006. The Board also approved the issuance of new classes of shares and new distribution arrangements with respect to these new share classes, including higher distribution fees for certain new share classes, which took effect after September 29, 2006. The Board also approved revised front-end sales charge schedules with respect to certain classes of shares of the Fund. To assist the Board in its consideration of the BlackRock Investment Advisory Agreement, BlackRock provided materials and information about BlackRock, including its financial condition and asset management capabilities and organization, and Merrill Lynch provided materials and information about the Transaction. The independent trustees, through their independent legal counsel, also requested and received additional information from Merrill Lynch and BlackRock in connection with their consideration of the BlackRock Investment Advisory Agreement. The additional information was provided in advance of the May 9, 2006 meeting. In addition, the independent trustees consulted with their counsel and Fund counsel on numerous occasions, discussing, among other things, the legal standards and certain other considerations relevant to the trustees' deliberations. At the Board meetings, the trustees discussed with Merrill Lynch management and certain BlackRock representatives the Transaction, its strategic rationale and BlackRock's general plans and intentions regarding the Fund. At these Board meetings, representatives of Merrill Lynch and BlackRock made presentations to and responded to questions from the Board. The trustees also inquired about the plans for and anticipated roles and responsibilities of certain employees and officers of the Previous Investment Adviser, and of its affiliates, to be transferred to BlackRock in connection with the Transaction. The independent trustees of the Board also conferred separately and with their counsel about the Transaction and other matters related to the Transaction on a number of occasions, including in connection with the April and May 2006 meetings. After the presentations and after reviewing the written materials provided, the independent trustees met in executive sessions with their counsel to consider the BlackRock Investment Advisory Agreement. In connection with the Board's review of the BlackRock Investment Advisory Agreement, Merrill Lynch and/or BlackRock advised the trustees about a variety of matters. The advice included the following, among other matters: o that there was not expected to be any diminution in the nature, quality and extent of services provided to the Fund and its shareholders by BlackRock Advisors, including compliance services; o that operation of New BlackRock as an independent investment management firm would enhance its ability to attract and retain talented professionals; o that the Fund was expected to benefit from having access to BlackRock's state of the art technology and risk management analytic tools, including investment tools, provided under the BlackRock Solutions(R) brand name; o that BlackRock had no present intention to alter any applicable expense waivers or reimbursements that were currently in effect and, while it reserved the right to do so in the future, it would seek the approval of the Board before making any changes; o that BlackRock and Merrill Lynch would enter into an agreement, for an initial three-year period and automatically renewable from year to year thereafter, in connection with the Transaction under which Merrill Lynch-affiliated broker-dealers would continue to offer the Fund as an investment product; BLACKROCK NEW YORK MUNICIPAL BOND FUND SEPTEMBER 30, 2006 25 Disclosure of New Investment Advisory Agreement (continued) o that BlackRock Advisors would have substantially the same access to the Merrill Lynch sales force when distributing shares of the Fund as was currently being provided to the Previous Investment Adviser and that other arrangements between the Previous Investment Adviser and Merrill Lynch sales channels would be preserved; o that the Fund would have access to BlackRock's network of third party brokers, retirement plan platforms and registered investment advisers; o that in connection with the Transaction, Merrill Lynch and BlackRock had agreed to conduct, and use reasonable best efforts to cause their respective affiliates to conduct, their respective businesses in compliance with the conditions of Section 15(f) of the Investment Company Act of 1940 (the "1940 Act") in relation to any public funds advised by BlackRock or the Previous Investment Adviser (or affiliates), respectively; and o that Merrill Lynch and BlackRock would derive benefits from the Transaction and that, as a result, they had a financial interest in the matters being considered that was different from that of Fund shareholders. The trustees considered the information provided by Merrill Lynch and BlackRock above, and, among other factors, the following: o the potential benefits to Fund shareholders from being part of a combined fund family with BlackRock-sponsored funds, including possible economies of scale and access to investment opportunities; o the potential for expanding distribution of Fund shares through improved access to third party distribution; o the reputation, financial strength and resources of BlackRock and its investment advisory subsidiaries and the anticipated financial strength and resources of New BlackRock; o the compliance policies and procedures of BlackRock Advisors; o the terms and conditions of the BlackRock Investment Advisory Agreement, including the fact that the Fund's advisory fee schedule would not increase under the BlackRock Investment Advisory Agreement, but would remain the same; o that in February 2006, the Board had performed a full annual review of the Previous Investment Advisory Agreement, as required by the 1940 Act, and had determined that the Previous Investment Adviser had the capabilities, resources and personnel necessary to provide the advisory and administrative services that were then being provided to the Fund; and that the advisory and/or management fees paid by the Fund, taking into account any applicable agreed-upon fee waivers and breakpoints, had represented reasonable compensation to the Previous Investment Adviser in light of the services provided, the costs to the Previous Investment Adviser of providing those services, economies of scale, the fees and other expenses paid by similar funds (including information provided by Lipper Inc. ["Lipper"]), and such other matters as the trustees had considered relevant in the exercise of their reasonable judgment; and o that Merrill Lynch had agreed to pay all expenses of the Fund in connection with the Board's consideration of the BlackRock Investment Advisory Agreement and related agreements and all costs of shareholder approval of the BlackRock Investment Advisory Agreement and as a result the Fund would bear no costs in obtaining shareholder approval of the BlackRock Investment Advisory Agreement. Certain of these considerations are discussed in more detail below. In its review of the BlackRock Investment Advisory Agreement, the Board assessed the nature, quality and scope of the services to be provided to the Fund by the personnel of BlackRock Advisors and its affiliates, including administrative services, shareholder services, oversight of fund accounting, marketing services and assistance in meeting legal and regulatory requirements. In its review of the BlackRock Investment Advisory Agreement, the Board also considered a range of information in connection with its oversight of the services to be provided by BlackRock Advisors and its affiliates. Among the matters considered were: (a) fees (in addition to management fees) to be paid to BlackRock Advisors and its affiliates by the Fund; (b) Fund operating expenses paid to third parties; (c) the resources devoted to and compliance reports relating to the Fund's investment objective, policies and restrictions, and its compliance with its Code of Ethics and BlackRock Advisors' compliance policies and procedures; and (d) the nature, cost and character of non-investment management services to be provided by BlackRock Advisors and its affiliates. 26 BLACKROCK NEW YORK MUNICIPAL BOND FUND SEPTEMBER 30, 2006 In the period prior to the Board meeting to consider renewal of the Previous Investment Advisory Agreement, the Board had requested and received materials specifically relating to the Previous Investment Advisory Agreement. These materials included (a) information compiled by Lipper on the fees and expenses and the investment performance of the Fund as compared to a comparable group of funds as classified by Lipper; (b) a discussion by the Fund's portfolio management team on investment strategies used by the Fund during its most recent fiscal year; (c) information on the profitability to the Previous Investment Adviser of the Previous Investment Advisory Agreement and other payments received by the Previous Investment Adviser and its affiliates from the Fund; and (d) information provided by the Previous Investment Adviser concerning services related to the valuation and pricing of Fund portfolio holdings, the Fund's portfolio turnover statistics, and direct and indirect benefits to the Previous Investment Adviser and its affiliates from their relationship with the Fund. In their deliberations, the trustees considered information received in connection with their most recent approval of the continuance of the Previous Investment Advisory Agreement, in addition to information provided by BlackRock and BlackRock Advisors in connection with their evaluation of the terms and conditions of the BlackRock Investment Advisory Agreement. The trustees did not identify any particular information that was all-important or controlling. The trustees, including a majority of the independent trustees, concluded that the terms of the BlackRock Investment Advisory Agreement are appropriate, that the fees to be paid are reasonable in light of the services to be provided to the Fund, and that the BlackRock Investment Advisory Agreement should be approved and recommended to Fund shareholders. Nature, Quality and Extent of Services Provided -- The Board reviewed the nature, quality and extent of services provided by the Previous Investment Adviser, including the investment advisory services and the resulting performance of the Fund, as well as the nature, quality and extent of services expected to be provided by BlackRock Advisors. The Board focused primarily on the Previous Investment Adviser's investment advisory services and the Fund's investment performance, but also considered certain areas in which both the Previous Investment Adviser and the Fund received services as part of the Merrill Lynch complex. The Board compared the Fund's performance -- both including and excluding the effects of fees and expenses -- to the performance of a comparable group of mutual funds, and the performance of a relevant index or combination of indexes. While the Board reviews performance data at least quarterly, consistent with the Previous Investment Adviser's investment goals, the Board attaches more importance to performance over relatively long periods of time, typically three to five years. In evaluating the nature, quality and extent of the services to be provided by BlackRock Advisors under the BlackRock Investment Advisory Agreement, the trustees considered, among other things, the expected impact of the Transaction on the operations, facilities, organization and personnel of New BlackRock and how it would affect the Fund; the ability of BlackRock Advisors to perform its duties after the Transaction; and any anticipated changes to the investment and other practices of the Fund. The trustees were given information with respect to the potential benefits to the Fund and its shareholders from having access to BlackRock's state of the art technology and risk management analytic tools, including the investment tools provided under the BlackRock Solutions brand name. The trustees were advised that, as a result of Merrill Lynch's equity interest in BlackRock after the Transaction, the Fund would continue to be subject to restrictions concerning certain transactions involving Merrill Lynch affiliates (for example, transactions with a Merrill Lynch broker-dealer acting as principal) absent revised or new regulatory relief. The trustees were advised that a revision of existing regulatory relief with respect to these restrictions was being sought from the Securities and Exchange Commission and were advised of the possibility of receipt of such revised regulatory relief. Based on their review of the materials provided and the assurances they had received from the management of Merrill Lynch and of BlackRock, the trustees determined that the nature and quality of services to be provided to the Fund under the BlackRock Investment Advisory Agreement were expected to be as good as or better than that provided under the Previous Investment Advisory Agreement. The trustees were advised that BlackRock Advisors did not plan to change the Fund's portfolio management team upon the closing of the transaction. It was noted, however, that other changes in personnel were expected to follow the Transaction and the combination of the operations of the Previous Investment Adviser and its affiliates with those of BlackRock. The trustees noted that if portfolio managers or other personnel were to cease to be available prior to the closing of the Transaction, the Board would consider all available options, including seeking the investment advisory or other services of BLACKROCK NEW YORK MUNICIPAL BOND FUND SEPTEMBER 30, 2006 27 Disclosure of New Investment Advisory Agreement (concluded) BlackRock affiliates. Accordingly, the trustees concluded that, overall, they were satisfied with assurances from BlackRock and BlackRock Advisors as to the expected nature, quality and extent of the services to be provided to the Fund under the BlackRock Investment Advisory Agreement. Costs of Services Provided and Profitability -- It was noted that, in conjunction with the recent review of the Previous Investment Advisory Agreement, the trustees had received, among other things, a report from Lipper comparing the Fund's fees and expenses to those of a peer group selected by Lipper, and information as to the fees charged by the Previous Investment Adviser or its affiliates to other registered investment company clients for investment management services. The Board reviewed the Fund's contractual management fee rate and actual management fee rate as a percentage of total assets at common asset levels -- the actual rate includes advisory fees and the effects of any fee waivers -- compared to the other funds in its Lipper category. They also compared the Fund's total expenses to those of other comparable funds. The information showed that the Fund had fees and expenses within the range of fees and expenses of comparable funds. The Board considered the services to be provided by and the fees to be charged by BlackRock Advisors to other funds with similar investment mandates and noted that the fees charged by BlackRock Advisors in those cases, including fee waivers and expense reimbursements, were generally comparable to those being charged to the Fund. The Board concluded that the Fund's management fee and fee rate and overall expense ratio are reasonable compared to those of other comparable funds. In evaluating the costs of the services to be provided by BlackRock Advisors under the BlackRock Investment Advisory Agreement, the trustees considered, among other things, whether advisory fees or other expenses would change as a result of the Transaction. Based on their review of the materials provided and the fact that the BlackRock Investment Advisory Agreement is substantially similar to the Previous Investment Advisory Agreement in all material respects, including the rate of compensation, the trustees determined that the Transaction should not increase the total fees payable, including any fee waivers or after any expense caps or expense reimbursements, for advisory and administrative services. The trustees noted that it was not possible to predict how the Transaction would affect BlackRock Advisors' profitability from its relationship with the Fund. The trustees discussed with BlackRock Advisors its general methodology to be used in determining its profitability with respect to its relationship with the Fund and noted that they expect to receive profitability information from BlackRock Advisors on at least an annual basis. Fees and Economies of Scale -- The Board considered the extent to which economies of scale might be realized as the assets of the Fund increase and whether there should be changes in the management fee rate or structure in order to enable the Fund to participate in these economies of scale. The Board determined that changes were not currently necessary and that the Fund appropriately participated in these economies of scale. In reviewing the Transaction, the trustees considered, among other things, whether advisory fees or other expenses would change as a result of the Transaction. Based on the fact that the BlackRock Investment Advisory Agreement is substantially similar to the Previous Investment Advisory Agreement in all material respects, including the rate of compensation, the trustees determined that as a result of the Transaction, the Fund's total advisory fees would be no higher than the fees under the Previous Investment Advisory Agreement. The trustees concluded that because the rates for advisory fees for the Fund would be no higher than the fee rates in effect at the time, the proposed management fee structure, including any fee waivers, was reasonable and that no additional changes were currently necessary. Fall-Out Benefits -- The trustees considered whether the Fund would generate any fall-out benefits to BlackRock Advisors. Fall-out benefits are indirect profits from other activities that accrue to the adviser or its affiliates solely because of the existence of the Fund. In evaluating the fall-out benefits to be received by BlackRock Advisors under the BlackRock Investment Advisory Agreement, the trustees considered whether BlackRock Advisors would experience such benefits to the same extent that the Previous Investment Adviser was experiencing such benefits under the Previous Investment Advisory Agreement. Based on their review of the materials provided, including materials received in connection with their most recent approval of the continuance of the Previous Investment Advisory Agreement, and their discussions with management of the Previous Investment Adviser and BlackRock, the trustees determined that those benefits could include increased ability for BlackRock to distribute shares of its funds and other investment products. The trustees noted that any such benefits were difficult to quantify with certainty at this time. 28 BLACKROCK NEW YORK MUNICIPAL BOND FUND SEPTEMBER 30, 2006 Investment Performance -- The trustees considered investment performance for the Fund. The trustees compared the Fund's performance -- both including and excluding the effects of fees and expenses -- to the performance of a comparable group of mutual funds, and the performance of a relevant index or combination of indexes. The comparative information received from Lipper showed Fund performance at various levels within the range of performance of comparable funds over different time periods. The trustees believed the Fund's performance was satisfactory. Also, the trustees took into account the investment performance of funds advised by BlackRock Advisors. The Board considered comparative information from Lipper which showed that the performance of the funds advised by BlackRock Advisors was within the range of performance of comparable funds over different time periods. The Board noted BlackRock's considerable investment management experience and capabilities, but was unable to predict what effect, if any, consummation of the Transaction would have on the future performance of the Fund. Conclusion -- After the independent trustees of the Fund deliberated in executive session, the entire Board, including the independent trustees, approved the BlackRock Investment Advisory Agreement, concluding that the advisory fee rate was reasonable in relation to the services provided and that the BlackRock Investment Advisory Agreement was in the best interests of the shareholders. In approving the BlackRock Investment Advisory Agreement, the Board noted that it anticipated reviewing the continuance of the agreement in advance of the expiration of the initial two-year period. New BlackRock Sub-Advisory Agreement -- Matters Considered by the Board At an in-person meeting held on August 22-23, 2006, the Board of Trustees, including the independent trustees, discussed and approved the sub-advisory agreement (the "BlackRock Sub-Advisory Agreement") between BlackRock Advisors and its affiliate, BlackRock Investment Management, LLC (the "Sub-Adviser"). The BlackRock Sub-Advisory Agreement became effective on September 29, 2006, at the same time the BlackRock Investment Advisory Agreement became effective. Pursuant to the BlackRock Sub-Advisory Agreement, the Sub-Adviser receives a monthly fee from BlackRock Advisors equal to 59% of the advisory fee received by BlackRock Advisors from the Fund. BlackRock Advisors pays the Sub-Adviser out of its own resources, and there is no increase in Fund expenses as a result of the BlackRock Sub-Advisory Agreement. In approving the BlackRock Sub-Advisory Agreement at the August in-person meeting, the Board reviewed its considerations in connection with its approval of BlackRock Investment Advisory Agreement in May 2006. The Board relied on the same information and considered the same factors as those discussed above in connection with the approval of the BlackRock Investment Advisory Agreement, and came to the same conclusions. In reviewing the sub-advisory fee rate provided in the BlackRock Sub-Advisory Agreement, the Board noted the fact that both BlackRock Advisors and the Sub-Adviser have significant responsibilities under their respective advisory agreements. BlackRock Advisors remains responsible for oversight of the Fund's operations and administration, and the Sub-Adviser provides advisory services to the Fund and is responsible for the day-to-day management of the Fund's portfolio under the BlackRock Sub-Advisory Agreement. The Board also took into account the fact that there is no increase in total advisory fees paid by the Fund as a result of the BlackRock Sub-Advisory Agreement. Under all of the circumstances, the Board concluded that it was a reasonable allocation of fees for the Sub-Adviser to receive 59% of the advisory fee paid by the Fund to BlackRock Advisors. After the independent trustees deliberated in executive session, the entire Board, including the independent trustees, approved the BlackRock Sub-Advisory Agreement, concluding that the sub-advisory fee was reasonable in relation to the services provided and that the BlackRock Sub-Advisory Agreement was in the best interests of shareholders.

Audit, audit-related and tax compliance services provided to the registrant on an annual basis require specific pre-approval by the Committee. The Committee also must approve other non-audit services provided to the registrant and those non-audit services provided to the registrant's affiliated service providers that relate directly to the operations and the financial reporting of the registrant. Certain of these non-audit services that the Committee believes are a) consistent with the SEC's auditor independence rules and b) routine and recurring services that will not impair the independence of the independent accountants may be approved by the Committee without consideration on a specific case-by-case basis ("general pre-approval"). However, such services will only be deemed pre-approved provided that any individual project does not exceed $5,000 attributable to the registrant or $50,000 for all of the registrants the Committee oversees. Any proposed services exceeding the pre-approved cost levels will require specific pre-approval by the Committee, as will any other services not subject to general pre-approval (e.g., unanticipated but permissible services). The Committee is informed of each service approved subject to general pre-approval at the next regularly scheduled in-person board meeting.

Item 11 - Controls and Procedures 11(a) - The Registrant's principal executive and principal financial officers have evaluated the Registrant's disclosure controls and procedures, including internal control over financial reporting, within 90 days of this filing. Such principal officers have concluded that the Registrant's disclosure controls and procedures were effective in design and operation to reasonably ensure that information required to be disclosed by the Registrant in this Form N-CSR was recorded, processed, summarized, and reported within the required time periods, and were sufficient to form the basis of the certifications required by Rule 30a-(2) of the Investment Company Act of 1940, as amended. Prior to reaching that conclusion, such principal officers had become aware of matters relating to the Registrant's participation in certain inverse floater structures that necessitated adjustments to financial information included in Item 1 of this filing. As a result, management of the Registrant has reevaluated certain disclosure controls and procedures determined not to be effective, as discussed more fully below. Management of the Registrant is responsible for establishing and maintaining effective internal control over financial reporting. In fulfilling this responsibility, estimates and judgments by management are required to assess the expected benefits and related costs of controls. The Registrant's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with U.S. generally accepted accounting principles. Such internal control includes policies and procedures that provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of a registrant's assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. A control deficiency exists when the design or operation of a control does not allow management or employees, in the normal course of performing their assigned functions, to prevent or detect misstatements on a timely basis. A significant deficiency is a control deficiency, or combination of control deficiencies, that adversely affects the Registrant's ability to initiate, authorize, record, process or report financial data reliably in accordance with generally accepted accounting principles such that there is more than a remote likelihood that a misstatement of the Registrant's annual or interim financial statements that is more than inconsequential will not be prevented or detected. A material weakness is a significant deficiency, or combination of significant deficiencies, that results in more than a remote likelihood that a material misstatement of the annual or interim financial statements will not be prevented or detected. Prior to the filing of this Form N-CSR, the Registrant identified the following control deficiency, that was determined to be a material weakness, as defined above, in the Registrant's internal control over financial reporting. The Registrant's controls related to the review and analysis of relevant terms and conditions of transfers of certain assets pertaining to inverse floater structures were not operating effectively to appropriately determine whether the transfers of assets qualified for sale accounting under the provisions of Statement of Financial Accounting Standards No. 140, "Accounting for Transfers and Servicing of Financial Assets and Extinguishments of Liabilities" ("SFAS 140"). Accordingly, the Registrant's financial statements as of and for the period ended October 31, 2006, including prior periods where applicable, were adjusted prior to being issued to appropriately reflect transfers of such securities as secured borrowings and to report the related income and expense. These adjustments had no impact on net assets, net asset value per share or total return. Management of the Registrant believes that subsequent to the adjustments, the Registrant's accounting treatment of such transfers is appropriate under SFAS 140. Additionally, management of the Registrant is taking such further actions as are necessary to enhance its internal control over financial reporting, and in doing so, increase the effectiveness of such controls, so that such transfers of assets are reviewed and evaluated appropriately under the provisions of SFAS 140. 11(b) - There have been no changes in the Registrant's internal control over financial reporting (as defined in Rule 30a-3(d) under the Investment Company Act of 1940, as amended) that occurred during the second half of the Registrant's fiscal year that have materially affected, or are reasonably likely to materially affect, the Registrant's internal control over financial reporting. However, as discussed above, subsequent to October 31, 2006, the Registrant is further enhancing controls related to the application of SFAS 140.
