A Letter to Shareholders

Dear Shareholder

It is my pleasure to welcome you to BlackRock.

On September 29, 2006, BlackRock, Inc. ("BlackRock") and Merrill Lynch
Investment Managers, L.P. ("MLIM") united to form one of the largest asset
management firms in the world. Now with more than $1 trillion in assets under
management, over 4,000 employees in 18 countries and representation in key
markets worldwide, BlackRock's global presence means greater depth and scale to
serve you.

The new BlackRock unites some of the finest money managers in the industry. Our
ranks include more than 500 investment professionals globally -- portfolio
managers, research analysts, risk management professionals and traders. With
offices strategically located around the world, our investment professionals
have in-depth local knowledge and the ability to leverage our global presence
and robust infrastructure to deliver focused investment solutions. BlackRock's
professional investors are supported by disciplined investment processes and
best-in-class technology, ensuring that our portfolio managers are well equipped

the belief that experienced investment and risk professionals using disciplined

value to client portfolios.

As you probably are aware, most former MLIM investment products now carry the
"BlackRock" name. This is reflected in newspapers and online fund reporting
resources. Your account statements, as of the October month-end reporting

your funds maintain the same investment objectives that they did prior to the
combination of MLIM and BlackRock. Importantly, this union does not affect your
brokerage account or your relationship with your financial advisor. Clients of
Merrill Lynch remain clients of Merrill Lynch.

We view this combination of asset management leaders as a complementary union
that reinforces our commitment to shareholders. Individually, each firm made
investment performance its single most important mission. Together, we are even
better prepared to capitalize on market opportunities on behalf of our
shareholders. Our focus on investment excellence is accompanied by an unwavering
commitment to service, enabling us to assist clients, in cooperation with their
financial professionals, in working toward their investment goals. We thank you
for allowing us the opportunity, and we look forward to serving your investment
needs in the months and years ahead as the new BlackRock.

                                                         Vice Chairman
                                                         BlackRock, Inc.

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.

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 an account maintenance 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 an
      account maintenance 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 account maintenance 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 account maintenance, 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.

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.

The first table 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."

The second table 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 table 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.

*     For each class of the Fund, expenses are equal to the annualized expense
      ratio for the class (.83% for Class A, 1.24% for Class B, 1.33% for Class
      C and .73% for Class I), multiplied by the average account value over the
      period, multiplied by 182/365 (to reflect the one-half year period shown).
**    Hypothetical 5% annual return before expenses is calculated by pro-rating
      the number of days in the most recent fiscal half year divided by 365.

Notes to Financial Statements

1. 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.

Notes to Financial Statements (continued)

(c) 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.

(d) 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.

(e) 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.

(f) Prepaid registration fees -- Prepaid registration fees are charged to
expense as the related shares are issued.

(g) 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.

(h) 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 & 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 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:

- --------------------------------------------------------------------------------
                                                Account            Distribution
                                             Maintenance 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 account
maintenance 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.

Notes to Financial Statements (continued)

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 are 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.

5. 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 ...............................         (17,122,042)*
Unrealized gains -- net .................................          18,576,852**
                                                                 ------------
Total accumulated earnings -- net .......................        $  1,726,651
                                                                 ============

*     On September 30, 2006, the Fund had a net capital loss carryforward of
      $17,122,042, of which $8,186,835 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
      and the realization for tax purposes of unrealized gains (losses) on
      certain futures contracts.

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 Common Stock 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.

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.

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      23


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.


24      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      25


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.


26      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.

         (e)(1) The registrant's audit committee (the "Committee") has adopted
         policies and procedures with regard to the pre-approval of services.
         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

         registrant's affiliated service providers that relate directly to the
         operations and the financial reporting of the registrant. Certain of

         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.

         the provision of non-audit services that were rendered to the
         registrant's investment adviser and any entity controlling, controlled
         by, or under common control with the investment adviser that provides
