A Letter to Shareholders


Dear Shareholder


The October reporting period was fairly tumultuous for financial markets, but
culminated in positive performance for most major benchmarks:




Total Returns as of October 31, 2007                                                  6-month        12-month
                                                                                               
U.S. equities (S&P 500 Index)                                                          +5.49%        +14.56%

Subprime mortgage woes dominated headlines for much of 2007, but intensified
in the summer and fall, spawning a widespread liquidity and credit crisis with
ramifications across global markets. The Federal Reserve Board (the "Fed") and
other countries' central banks stepped in to inject liquidity into the markets
and bolster investor confidence. The Fed cut the federal funds rate by 0.50%
in September and another 0.25% on the final day of the reporting period,
bringing its target rate to 4.50%. In taking action, the central bankers, who
had long deemed themselves inflation fighters, were seeking to stem the
fallout from the credit crunch and forestall a wider economic unraveling. By
period-end, the Fed had cited the risks between slower economic growth and
faster inflation as equally balanced.

Amid the volatility throughout the past year, equity markets have displayed
surprising resilience. Most recently, the credit turmoil dampened corporate
merger-and-acquisition (M&A) activity, a key source of strength for equity
markets. Still, market fundamentals have held firm, dividend payouts and share
buybacks have continued to grow, and valuations remain attractive. These
tailwinds generally have prevailed over the headwinds created by the slowing
U.S. economy, troubled housing market and, recently, a more difficult
corporate earnings backdrop. International markets fared even better than U.S.
equities, benefiting from robust M&A activity and generally stronger economies.

In fixed income markets, mixed economic signals and the credit woes resulted
in a flight to quality. At the height of the uncertainty, investors shunned
bonds associated with the housing and credit markets in favor of higher-
quality Treasury issues. The yield on 10-year Treasury issues, which touched
5.30% in June (its highest level in five years), fell to 4.48% by period-end,
while prices correspondingly rose. The tax-exempt bond market has been
challenged by a combination of record-setting supply year-to-date, economic
uncertainty and concerns around the credit worthiness of bond insurers. This
has brought municipal bond prices to relatively attractive levels and, as
such, demand generally has remained firm.

As you navigate market volatility, we encourage you to review your investment
goals with your financial professional and to make portfolio changes, as
needed. For more market insight and commentary from BlackRock investment
professionals, we invite you to visit www.blackrock.com/funds. As always, we
thank you for entrusting BlackRock with your investment assets, and we look
forward to continuing to serve you in the months and years ahead.


Sincerely,


/s/ Robert C. Doll, Jr.

Fund Summary


Portfolio Management Commentary


  How did the Fund perform?

* The Fund posted solid absolute returns, but underperformed its benchmark
  for the 12-month period.


  What factors Influenced performance?

* The main detractor from performance was the Fund's overweight in
  financials, especially in banking and diversified financials. We have been
  positioned for tougher markets and materially reduced our exposure to the
  sector throughout the year, but the extent of liquidity contagion from the
  subprime markets and the resulting risk aversion across the sector led to a
  broad-based sell-off that affected a number of the Fund's holdings,
  including U.K. bank HBOS Plc, Irish bank Allied Irish Banks Plc and Swiss
  investment bank UBS AG.

* The Fund's exposure to the automobile industry underperformed on concerns
  that a U.S. consumer slowdown, along with a weaker U.S. dollar, would
  negatively impact demand. Relative returns also suffered from not owning
  Finnish handset maker Nokia Oyj, and from the Fund's holdings in Irish
  construction company CRH Plc and Belgium imaging technology company AGFA
  Gevaert NV.

* The Fund's large cap bias detracted from performance relative to its
  benchmark, especially in the latter part of 2006 and early 2007, when
  merger-and-acquisition activity reached record levels and tended to benefit
  mid to small cap names. The Fund's value bias also was a relative
  disadvantage, as value underperformed growth for the year.

* The Fund benefited from an overweight exposure to oil prices, reflected
  through energy holdings such as Statoilhydro ASA and refiner MOL Hungarian
  Oil and Gas, and power utilities such as RWE AG, E.ON AG and Electricite de
  France SA. Other stocks that contributed positively included German
  chemical/pharmaceutical company Bayer AG, steel company Arcelor-Mittal,
  construction company Hochtief AG and chemical company BASF AG.


  Describe recent portfolio activity.

* We reduced exposure to the financial sector across banks, diversified
  financials and insurance, including ING Groep NV CVA, French banks BNP
  Paribas and Credit Agricole SA, Banco Bilbao Vizcaya Argentaria SA and
  Barclays Plc. We increased our defensive exposure in the food, beverage &
  tobacco subsector, with increases in Unilever Plc, Nestle SA and British
  American Tobacco Plc. We also added to the materials sector, through Anglo
  American Plc and chemical company Akzo Nobel NV. Other new or increased
  positions included Deutsche Telekom AG, DaimlerChrysler AG and Banco
  Santander SA.


  Describe Fund positioning at period-end.

* We remain optimistic on the prospects for European equities. In our view,
  the recent equity market sell-off is not the result of any specific issues
  in Europe, although some banks may have some moderate exposure to the
  credit market crisis. While it is too early to know if the market has hit
  bottom, we are actively looking for opportunities among stocks that we
  believe are now oversold. In our view, a combination of strong earnings
  growth and attractive valuations should allow the market to make progress
  against what may be a more challenging international backdrop.

About Fund Performance


* Institutional Shares are not subject to any sales charge. Institutional
  Shares bear no ongoing distribution or service fees and are available only
  to eligible investors.

* Investor A Shares incur a maximum initial sales charge (front-end load) of
  5.25% and a service fee of 0.25% per year (but no distribution fee).

* Investor B Shares are subject to a maximum contingent deferred sales charge
  of 4.50% declining to 0% after six years. In addition, Investor B Shares
  are subject to a distribution fee of 0.75% per year and a service fee of
  0.25% per year. These shares automatically convert to Investor A Shares
  after approximately eight years. (There is no initial sales charge for
  automatic share conversions.) All returns for periods greater than eight
  years reflect this conversion.

* Investor C Shares are subject to a distribution fee of 0.75% per year and a
  service fee of 0.25% per year. In addition, Investor C Shares are subject
  to a 1% contingent deferred sales charge if redeemed within one year of
  purchase.

* Class R Shares do not incur a maximum initial sales charge (front-end load)
  or deferred sales charge. These shares are subject to a distribution fee of
  0.25% per year and a service fee of 0.25% per year. Class R Shares are
  available only to certain retirement plans. Prior to inception, Class R
  Share performance results are those of the Institutional Shares (which have
  no distribution or service fees) restated to reflect Class R Share fees.

Performance information reflects past performance and does not guarantee
future results. Current performance may be lower or higher than the
performance data quoted. Refer to www.blackrock.com/funds 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. The Fund may charge a 2%
redemption fee for sales or exchanges of shares within 30 days of purchase or
exchange. Performance data does not reflect this potential fee. Figures shown
in each of the performance tables on pages 4 and 5 assume reinvestment of all
dividends and capital gain distributions, if any, at net asset value on the
ex-dividend 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.



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 expense
example on page 5 (which is based on a hypothetical investment of $1,000
invested on May 1, 2007 and held through October 31, 2007) 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 table 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 corresponding to their share
class under the heading entitled "Expenses Paid During the Period."

The table also 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 hypothetical
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.

BLACKROCK EUROFUND                                             OCTOBER 31, 2007



Notes to Financial Statements


1. Significant Accounting Policies:

BlackRock EuroFund (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. Institutional Shares are sold without
a sales charge and only to certain eligible investors. Investor A Shares are
sold with a front-end sales charge. Shares of Investor B and Investor C may be
subject to a contingent deferred sales charge. Class R Shares are sold only to
certain retirement plans. Institutional 1 Shares were issued in connection
with the Fund's acquisition of The Europe Fund, Inc. on November 6, 2006.
Institutional 1 Shares generally were not available for purchase except for
dividend and capital gain reinvestments for existing shareholders and
automatically converted to Institutional Shares on May 7, 2007. All classes of
shares have identical voting, dividend, liquidation and other rights and the
same terms and conditions, except that Investor A, Investor B, Investor C and
Class R Shares bear certain expenses related to the shareholder servicing of
such shares, and Investor B, Investor C and Class R 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 shareholder servicing
and distribution expenditures (except that Investor B shareholders may vote on
certain changes to the Investor A distribution plan). 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 securities--Equity securities held by the Fund that are
traded on stock exchanges or the NASDAQ Global Market are valued at the last
sale price or official close price on the exchange, as of the close of
business on the day the securities are being valued or, lacking any sales, at
the last available bid price for long positions, and at the last available
asked price for short positions. In cases where equity securities are traded
on more than one exchange, the securities are valued on the exchange
designated as the primary market by or under the authority of the Board of
Trustees of the Fund. Long positions traded in over-the-counter ("OTC")
markets, NASDAQ Capital Market or Bulletin Board are valued at the last
available bid price or yield equivalent obtained from one or more dealers or
pricing services approved by the Board of Trustees of the Fund. Short
positions traded in the OTC markets are valued at the last available asked
price. Portfolio securities that are traded both in the OTC markets and on a
stock exchange are valued according to the broadest and most representative
market.

Effective September 4, 2007, exchange-traded options are valued at the mean
between the last bid and ask prices at the close of the options market in
which the options trade and previously were valued at the last sales price as
of the close of options trading on applicable exchanges. Options traded in the
OTC market are valued at the last asked price (options written) or the last
bid price (options purchased). Swap agreements are valued based upon quoted
fair valuations received daily by the Fund from a pricing service or
counterparty. Financial futures contracts and options thereon, which are
traded on exchanges, are valued at their last sale price as of the close of
such exchanges. Valuation of other short-term investment vehicles is generally
based on the net asset value of the underlying investment vehicle or amortized
cost.

Repurchase agreements are valued at cost plus accrued interest. The Fund
employs pricing services to provide certain securities prices for the Fund.
Securities and 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 Fund, including valuations furnished by the
pricing services retained by the Fund, which may use a matrix system for
valuations. The procedures of a pricing service and its valuations are
reviewed by the officers of the Fund under the general supervision of the
Fund's Board of Trustees. Such valuations and procedures will be reviewed
periodically by the Board of Trustees of the Fund.

Generally, trading in foreign securities, as well as U.S. government
securities, money market instruments and certain fixed income securities,
is substantially completed each day at various times prior to the close of
business on the New York Stock Exchange ("NYSE"). The values of such
securities used in computing the net asset value of the Fund's shares are
determined as of such times. Foreign currency exchange rates will generally
be determined as of the close of business on the NYSE. Occasionally, events
affecting the values of such securities and such exchange rates may occur
between the times at which they are determined and the close of business on
the NYSE that may not be reflected in the computation of the Fund's net asset
value. If events (for example, a company announcement, market volatility or a
natural disaster) occur during such periods that are expected to materially
affect the value of such securities, those securities will be valued at their
fair value as determined in good faith by the Fund's Board of Trustees or by
the Manager using a pricing service and/or procedures approved by the Fund's
Board of Trustees.

(b) Foreign currency transactions--Transactions denominated in foreign
currencies are recorded at the exchange rate prevailing when recognized.
Assets and liabilities denominated in foreign currencies are valued at the
exchange rate at the end of the period. Foreign currency transactions are the
result of settling (realized) or valuing (unrealized) assets or liabilities
expressed in foreign currencies into U.S. dollars. Realized and unrealized
gains or losses from investments include the effects of foreign exchange rates
on investments. The Fund invests in foreign securities, which may involve a
number of risk factors and special considerations not present with investments
in securities of U.S. corporations.

Notes to Financial Statements (continued)


(c) 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 due to an unfavorable change in the price of the underlying security
or if the counterparty does not perform under the contract. The counterparty
for certain instruments may pledge cash or securities as collateral.

* Forward foreign exchange contracts--The Fund may enter into forward foreign
exchange contracts as a hedge against either specific transactions or
portfolio positions. The contract is marked-to-market daily and the change in
market value is recorded by the Fund as an unrealized gain or loss. When the
contract is closed, the Fund records a realized gain or loss equal to the
difference between the value at the time it was opened and the value at the
time it was closed.

* Options--The Fund may write covered call options and put options and
purchase put and call options. When the Fund writes an option, an amount equal
to the premium received by the Fund is reflected as an asset and an equivalent
liability. The amount of the liability is subsequently marked-to-market to
reflect the current market value of the option written. When a security is
purchased or sold through an exercise of an option, the related premium paid
(or received) is added to (or deducted from) the basis of the security
acquired or deducted from (or added to) the proceeds of the security sold.
When an option expires (or the Fund enters into a closing transaction), the
Fund realizes a gain or loss on the option to the extent of the premiums
received or paid (or gain or loss to the extent the cost of the closing
transaction exceeds the premium paid or received).

Written and purchased options are non-income producing investments.

* Foreign currency options and futures--The Fund may also purchase or sell
listed or OTC foreign currency options, foreign currency futures and related
options on foreign currency futures as a short or long hedge against possible
variations in foreign exchange rates. Such transactions may be effected with
respect to hedges on non-U.S. dollar denominated securities owned by the Fund,
sold by the Fund but not yet delivered, or committed or anticipated to be
purchased by the Fund.

(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. Under the applicable
foreign tax law, a withholding tax may be imposed on interest, dividends and
capital gains at various rates.

(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.
Dividends from foreign securities where the ex-dividend date may have passed
are subsequently recorded when the Fund has determined the ex-dividend date.
Interest income is recognized on the accrual basis.

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

(g) Dividends and distributions--Dividends and distributions paid by the Fund
are recorded on the ex-dividend dates.

(h) Securities lending--The Fund may lend securities to financial
institutions that provide cash or securities issued or guaranteed by the U.S.
government as collateral, which will be maintained at all times in an amount
equal to at least 100% of the current market value of the loaned securities.
The market value of the loaned securities is determined at the close of
business of the Fund and any additional required collateral is delivered to
the Fund on the next business day. Where the Fund receives securities as
collateral for the loaned securities, it collects a fee from the borrower.
The Fund typically receives the income on the loaned securities but does not
receive the income on the collateral. Where the Fund receives cash
collateral, it may invest such collateral and retain the amount earned on
such investment, net of any amount rebated to the borrower. Loans of
securities are terminable at any time and the borrower, after notice, is
required to return borrowed securities within five business days. The Fund
may pay reasonable finder's, lending agent, administrative and custodial fees
in connection with its loans. In the event that the borrower defaults on its
obligation to return borrowed securities because of insolvency or for any
other reason, the Fund could experience delays and costs in gaining access to
the collateral. The Fund also could suffer a loss where the value of the
collateral falls below the market value of the borrowed securities, in the
event of borrower default or in the event of losses on investments made with
cash collateral.

(i) Recent accounting pronouncements--In July 2006, the Financial Accounting
Standards Board ("FASB") issued Interpretation No. 48 ("FIN 48"), "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 the last net asset value calculation in the first required
financial statement reporting period for fiscal years beginning after December
15, 2006. The impact on the Fund's financial statements, if any, is currently
being assessed.



BLACKROCK EUROFUND                                             OCTOBER 31, 2007



Notes to Financial Statements (continued)


In September 2006, Statement of Financial Accounting Standards No. 157, "Fair
Value Measurements" ("FAS 157") was issued and is effective for fiscal years
beginning after November 15, 2007. FAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. At this time, management is evaluating the implications of FAS
157 and its impact on the Fund's financial statements, if any, has not been
determined.

In addition, in February 2007, Statement of Financial Accounting Standards
No. 159, "The Fair Value Option for Financial Assets and Financial
Liabilities" ("FAS 159") was issued and is effective for fiscal years
beginning after November 15, 2007. Early adoption is permitted as of the
beginning of a fiscal year that begins on or before November 15, 2007,
provided the entity also elects to apply the provisions of FAS 157. FAS 159
permits entities to choose to measure many financial instruments and certain
other items at fair value that are not currently required to be measured at
fair value. FAS 159 also establishes presentation and disclosure requirements
designed to facilitate comparisons between entities that choose different
measurement attributes for similar types of assets and liabilities. At this
time, management is evaluating the implications of FAS 159 and its impact on
the Fund's financial statements, if any, has not been determined.

(j) Reclassification--U.S. generally accepted accounting principles require
that certain components of net assets be adjusted to reflect permanent
differences between financial and tax reporting. Accordingly, during the
current year, $4,048,978 has been reclassified between undistributed net
realized capital gains and undistributed net investment income as a result of
gains from the sale of stock of passive foreign investment companies and
foreign currency transactions. These reclassifications have no effect on net
assets or net asset values per share.


2. Investment Advisory Agreements and Transactions with Affiliates:

The Fund has entered into an Investment Advisory Agreement with the Manager.
The Fund has also entered into separate Distribution Agreements and
Distribution Plans with FAM Distributors, Inc. ("FAMD") and BlackRock
Distributors, Inc. and its affiliates ("BDI") (collectively, the
"Distributor"). FAMD is a wholly owned subsidiary of Merrill Lynch Group,
Inc., and BDI is an affiliate of BlackRock, Inc. Merrill Lynch & Co., Inc.
("Merrill Lynch") and The PNC Financial Services Group, Inc. ("PNC") are the
principal owners of BlackRock, Inc.

The Manager 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 at an annual rate of .75% on an annual basis of the average
daily value of the Fund's net assets.

In addition, the Manager has entered into a Sub-Advisory Agreement with
BlackRock Investment Management, LLC ("BIM"), and BlackRock Asset Management
U.K. Limited, both affiliates of the Manager, under which the Manager pays
each sub-adviser for services it provides a monthly fee at an annual rate that
is a percentage of the management fee paid by the Fund to the Manager.

Pursuant to the Distribution Plan adopted by the Fund in accordance with Rule
12b-1 under the Investment Company Act of 1940, the Fund pays the Distributor
ongoing service and distribution fees. The fees are accrued daily and paid
monthly at annual rates based upon the average daily net assets of the shares
as follows:


                                      Service          Distribution
                                          Fee                   Fee

Investor A                               .25%                    --
Investor B                               .25%                  .75%
Investor C                               .25%                  .75%
Class R                                  .25%                  .25%


Pursuant to sub-agreements with each Distributor, broker-dealers, including
Merrill Lynch, Pierce, Fenner & Smith Incorporated ("MLPF&S"), a wholly owned
subsidiary of Merrill Lynch, provide shareholder servicing and distribution
services to the Fund. The ongoing service fee compensates the Distributor and
each broker-dealer (including MLPF&S) for providing shareholder servicing to
Investor A, Investor B, Investor C and Class R shareholders. The ongoing
distribution fee compensates the Distributor and the broker-dealers for
providing shareholder servicing and distribution-related services to Investor
B, Investor C and Class R shareholders.

For the year ended October 31, 2007, FAMD and BDI earned underwriting
discounts and direct commissions and MLPF&S and BDI earned dealer concessions
on sales of the Fund's Investor A Shares, which totaled $133,533.

For the year ended October 31, 2007, affiliates received contingent deferred
sales charges of $10,709 and $8,752 relating to transactions in Investor B and
Investor C Shares, respectively.

Furthermore, affiliates received contingent deferred sales charges of $607
relating to transactions subject to front-end sales charge waivers in Investor
A Shares.

Notes to Financial Statements (continued)


The Manager maintains a call center, which is responsible for providing
certain shareholder services to the Fund, such as responding to shareholder
inquiries and processing transactions based upon instructions from
shareholders with respect to the subscription and redemption of Fund shares.
For the year ended October 31, 2007, the following amounts have been accrued
by the Fund to reimburse the Manager for costs incurred running the call
center, which are a component of the transfer agent fees in the accompanying
Statement of Operations.


                                                 Call Center

Institutional                                  $       9,660
Investor A                                     $      10,467
Investor B                                     $       1,664
Investor C                                     $       1,474
Class R                                        $          39


The Fund has received an exemptive order from the Securities and Exchange
Commission permitting it to lend portfolio securities to MLPF&S or its
affiliates. Pursuant to that order, the Fund has retained BIM, an affiliate
of the Manager, as the securities lending agent for a fee based on a share of
the returns on investment of cash collateral. BIM may, on behalf of the Fund,
invest cash collateral received by the Fund for such loans, among other
things, in a private investment company managed by the Manager or in
registered money market funds advised by the Manager or its affiliates.

For the year ended October 31, 2007, the Fund reimbursed the Manager $18,879
for certain accounting services.

PFPC Inc., an indirect, wholly owned subsidiary of PNC and an affiliate of the
Manager, is the Fund's transfer agent.

Certain officers and/or trustees of the Fund are officers and/or directors of
BlackRock, Inc. or its affiliates.


3. Investments:

Purchases and sales of investments, excluding short-term securities, for the
year ended October 31, 2007 were $611,040,933 and $786,348,245, respectively.


4. Beneficial Interest Transactions:

Net increase (decrease) in net assets derived from beneficial interest
transactions was $10,110,593 and $(33,186,593) for the year ended October 31,
2007 and October 31, 2006, respectively.

Transactions in beneficial interest for each class were as follows:

Notes to Financial Statements (concluded)



5. Short-Term Borrowings:

The Fund, along with certain other funds managed by the Manager and its
affiliates, is a party to a $500,000,000 credit agreement with a group of
lenders, which expires November 2007 and was subsequently renewed. 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 .35% or a base rate as
defined in the credit agreement. The Fund did not borrow under the credit
agreement during the year ended October 31, 2007.


6. Distributions to Shareholders:

The tax character of distributions paid during the fiscal years ended
October 31, 2007 and October 31, 2006 was as follows:


                                          10/31/2007         10/31/2006
Distributions paid from:
   Ordinary income                    $   26,823,003     $   14,440,973
   Net long-term capital gains        $   70,869,341                 --
                                      --------------     --------------
Total distributions                   $   97,692,344     $   14,440,973
                                      ==============     ==============


As of October 31, 2007, the components of accumulated earnings on a
tax basis were as follows:

Undistributed ordinary income--net                       $   46,587,353
Undistributed long-term capital gains--net                  132,085,236
                                                         --------------
Total undistributed earnings--net                           178,672,589
Capital loss carryforward                                  (8,158,403)*
Unrealized gains--net                                     263,855,751**
                                                         --------------
Total accumulated earnings--net                          $  434,369,937
                                                         ==============

 * On October 31, 2007, the Fund had a net capital loss carryforward
   of $8,158,403 all of which expires in 2009. 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 realization for tax purposes of unrealized gains on investments
   in passive foreign investment companies and the realization for tax
   purposes of unrealized gains (losses) on certain foreign currency
   contracts.


7. Commitments:

As of October 31, 2007, the Fund had entered into foreign exchange contracts
under which it had sold various foreign currencies with approximate value of
$4,053,000.


8. Acquisition of The Europe Fund, Inc.

On November 6, 2006, the Fund acquired substantially all of the assets and
assumed substantially all of the liabilities of The Europe Fund, Inc.,
pursuant to a plan of reorganization. The acquisition was accomplished by a
tax-free exchange of 10,066,319 shares of common stock of The Europe Fund,
Inc. for 5,532,829 shares of common stock of the Fund. The Europe Fund, Inc.'s
net assets on that date of $113,021,126, including $152,626 of distributions
in excess of net investment income, $141,914 of accumulated net realized
losses and $8,113,020 of net unrealized appreciation, were combined with those
of the Fund. The Fund's aggregate net assets immediately after the acquisition
amounted to $1,001,508,858.


9. Subsequent Event:

The Fund paid an ordinary income dividend in the amount of $1.170464 per
Institutional Share, $1.126287 per Investor A Share, $.870836 per Investor B
Share, $1.004501 per Investor C Share and $1.095411 per Class R Share on
December 17, 2007 to shareholders of record on December 13, 2007.

The Fund paid a long-term capital gain distribution in the amount of $3.170025
per Institutional Share, $3.170025 per Investor A Share, $3.170025 per
Investor B Share, $3.170025 per Investor C Share and $3.170025 per Class R
Share on December 17, 2007 to shareholders of record on December 13, 2007.

Report of Independent Registered Public Accounting Firm


To the Shareholders and Board of Trustees of
BlackRock EuroFund:

We have audited the accompanying statement of assets and liabilities,
including the schedule of investments, of BlackRock EuroFund (the "Fund") as
of October 31, 2007, 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 Fund'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 Fund 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 Fund'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 October 31, 2007, by correspondence with the
custodian. 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 EuroFund as of October 31, 2007, 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 accounting principles
generally accepted in the United States of America.

Item 3 -   Audit Committee Financial Expert - The registrant's board of
           directors or trustees, as applicable (the "board of directors") has
           determined that (i) the registrant has the following audit committee
           financial experts serving on its audit committee and (ii) each audit
           committee financial expert is independent:
           Ronald W. Forbes (term ended, effective November 1, 2007)
           Robert M. Hernandez (term began, effective November 1, 2007)
           Fred G. Weiss (term began, effective November 1, 2007)
           Richard R. West
           Edward D. Zinbarg (retired as of December 31, 2006)

           Under applicable securities laws, a person determined to be an audit
           committee financial expert will not be deemed an "expert" for any
           purpose, including without limitation for the purposes of Section 11
           of the Securities Act of 1933, as a result of being designated or
           identified as an audit committee financial expert.  The designation
           or identification as an audit committee financial expert does not
           impose on such person any duties, obligations, or liabilities
           greater than the duties, obligations, and liabilities imposed on
           such person as a member of the audit committee and board of
           directors in the absence of such designation or identification.

           (e)(1) Audit Committee Pre-Approval Policies and Procedures:
                  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 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.

           (e)(2) None of the services described in each of Items 4(b) through
                  (d) were approved by the audit committee pursuant to
                  paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X.

           (f) Not Applicable

           (g) Affiliates' Aggregate Non-Audit Fees:


                                        Current               Previous

           BlackRock EuroFund           $291,642             $2,936,383


           (h) The registrant's audit committee has considered and determined
           that the provision of non-audit services that were rendered to the
           registrant's investment adviser (not including any non-affiliated
           sub-adviser whose role is primarily portfolio management and is
           subcontracted with or overseen by the registrant's investment
           adviser), and any entity controlling, controlled by, or under common
           control with the investment adviser that provides ongoing services
           to the registrant that were not pre-approved pursuant to paragraph
           (c)(7)(ii) of Rule 2-01 of Regulation S-X is compatible with
           maintaining the principal accountant's independence.

Item 10 -  Submission of Matters to a Vote of Security Holders - The
           registrant's Nominating and Governance Committee will consider
           nominees to the Board recommended by shareholders when a vacancy
           becomes available.  Shareholders who wish to recommend a nominee
           should send nominations which include biographical information and
           set forth the qualifications of the proposed nominee to the
           registrant's Secretary.  There have been no material changes to
           these procedures.

Item 11 -  Controls and Procedures

11(a) -    The registrant's principal executive and principal financial
           officers or persons performing similar functions have concluded that
           the registrant's disclosure controls and procedures (as defined in
           Rule 30a-3(c) under the Investment Company Act of 1940, as amended
           (the "1940 Act")) are effective as of a date within 90 days of the
           filing of this report based on the evaluation of these controls and
           procedures required by Rule 30a-3(b) under the 1940 Act and Rule
           15d-15(b) under the Securities and Exchange Act of 1934, as amended.

11(b) -    There were no changes in the registrant's internal control over
           financial reporting (as defined in Rule 30a-3(d) under the 1940 Act)
           that occurred during the second fiscal quarter of the period covered
           by this report that have materially affected, or are reasonably
           likely to materially affect, the registrant's internal control over
           financial reporting.
