A Letter to Shareholders


Dear Shareholder

In its first four months, 2007 could already be termed an eventful year for
investors. For most financial markets, 2007 opened just as 2006 ended - on a
positive trajectory. Then, at the end of February and into March, global
equity markets registered their first significant decline since last summer.
The market jitters were triggered by a significant setback in the Chinese
market and were exacerbated by worries of a weakening economy, escalating
geopolitical concerns and rising delinquencies in the subprime mortgage
market. Still, underlying stock market fundamentals appeared quite sound,
supported by a generally favorable global economic backdrop, tame inflation,
slowing but still positive earnings growth, relatively low interest rates and
attractive valuations. These conditions prevailed later, and the Dow Jones
Industrial Average crossed the 13,000 mark for the first time in its history
in late April.

Not unlike the equity market, the bond market also experienced volatility as
observers attempted to interpret mixed economic signals. A bond market rally
(falling yields and rising prices) late last year reversed itself early in
2007 amid some transitory signs of economic strength. Overall, yields have
fluctuated month to month but ended April little changed from the beginning of
the year. However, compared to one year ago, yields on 30-year Treasury bonds
fell 36 basis points (.36%) and 10-year yields fell 44 basis points, while
prices correspondingly rose.

For its part, the Federal Reserve Board (the Fed) has left the target short-
term interest rate on hold at 5.25% since first pausing in its interest rate-
hiking campaign on August 8, 2006. The central bankers continue to express
concern about potential inflationary pressures, but also acknowledge signs of
economic weakness. Given this relatively "balanced" assessment, most observers
believe the Fed will keep interest rates on hold for now.

Against this backdrop, most major market indexes posted positive returns for
the annual and semi-annual reporting periods ended April 30, 2007:

If the first four months are any guide, 2007 could be a year of enhanced
market volatility. As you navigate the un-certainties, we encourage you to
review your investment goals with your financial professional and to make
portfolio changes, as needed. For more insight, we invite you to view "What's
Ahead in 2007: An Investment Perspective" and "Are You Prepared for
Volatility?" at www.blackrock.com/funds. 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,

A Discussion With Your Fund's Portfolio Manager


The Fund provided strong absolute performance for the period, but lagged the
MSCI Europe Index's return, as its large-cap bias did not allow it to benefit
from the robust merger-and-acquisition activity in European mid- and small-cap
stocks.


How did the Fund perform during the period in light of the existing market
conditions?

For the six-month period ended April 30, 2007, BlackRock EuroFund's
Institutional, Institutional 1, Investor A, Investor B, Investor C and Class R
Shares had total returns (in U.S. dollar terms) of +14.53%, +14.53%, +14.44%,
+13.84%, +13.96% and +14.15%, respectively. (Fund results shown do not reflect
sales charges and would be lower if sales charges were included. Complete
performance information can be found on pages 6 - 9 of this report to
shareholders.) For the same period, the benchmark Morgan Stanley Capital
International (MSCI) Europe Index returned +18.17% (net return in U.S. dollar
terms), and the Fund's comparable Lipper category of European Region Funds
posted an average return of +18.46%. (Funds in this Lipper category invest in
equity securities whose primary trading markets or operations are concentrated
in the European region or a single country within this region.)

Equity markets delivered healthy returns for the majority of the period before
suffering an abrupt correction at the end of February. The result was a broad-
based global equity decline, but markets quickly recovered and by period-end
had surpassed their previous highs.

Despite looming concerns of a slowdown in U.S. economic growth and more recent
concerns that a crisis in the U.S. subprime mortgage market could hurt
economic growth, the global economy has remained on track. European companies
have continued to deliver stronger-than-expected earnings growth and record
profits, driven by a combination of robust export demand (especially from the
faster-growing Asian economies) and a pick-up in domestic demand in Europe.

In an environment of positive earnings momentum, central banks have remained
active, with short-term interest rates moving higher in most regions. Both the
European Central Bank (ECB) and Bank of England (BoE) have continued to nudge
short-term rates higher in response to the healthier performance of the main
European economies and a modest rise in consumer price inflation. However,
monetary policy still remains accommodative, with inexpensive debt financing
leading to abundant levels of global liquidity and fueling corporate activity.
Mergers and acquisitions (M&A) have subsequently been a primary driver of
market returns, especially in Europe where record corporate activity has been
seen across a range of sectors.

The oil price, having reached a new high of $77 per barrel in August 2006,
declined to levels as low as $50 per barrel in January, but has since
recovered. This decline was attributed to an exceptionally mild winter,
increased global supply and concerns that a slowdown in global growth could
impact demand.

During the period, the Fund benefited from successful stock selection in the
materials sector, particularly through its exposure to the steel industry,
which has experienced robust global demand and increased pricing power, along
with chemical companies. The Fund's holdings in Arcelor Mittal, Bayer AG and
BASF AG were positive contributors to performance. An underweight position in
the pharmaceuticals sector also aided the Fund's relative returns.

The primary negative performance factor during the period was the Fund's
exposure to the financials sector, especially in the banking subsector where
the portfolio is overweight relative to its benchmark, the MSCI Europe Index.
The sector has fallen amid market concerns about the sustainability of capital-
markets-related revenue in the context of a slowing U.S. economy and subprime
market fallout, along with worries that rising interest rates could impact
retail loan growth. Over the last few months of the reporting period, M&A
activity also was a negative factor in terms of Fund returns. Specifically,
the Fund was negatively influenced by its avoidance of ABN Amro, which rose
sharply after an unexpected bid from Barclays Plc was quickly followed by
another offer from a consortium. This generated considerable speculation in
the sector which has, in general, tended to hold back stock values of
potential acquirers (typically large-cap banks to which the Fund is exposed)
and raise the value of potential targets (mid cap names in which the Fund is
underweight).



BLACKROCK EUROFUND                                               APRIL 30, 2007



Additional performance detractors included disappointing stock selection in
the consumer discretionary sector and an overweight position in the energy
sector. In consumer discretionary, the Fund's lack of ownership of Daimler
Chrysler AG hurt relative results as the automaker's stock rose sharply after
the company announced the sale of its struggling U.S. subsidiary, Chrysler.
The Fund's overweight position in the energy sector also hindered performance
as the sector fell in conjunction with the downward movement in oil prices.
Finally, selected holdings in the telecommunications and retail sectors, along
with a significant underweight in food, beverage & tobacco stocks, negatively
impacted the Fund's relative results.


What changes were made to the portfolio during the period?

During the six-month period, we increased the Fund's exposure to the
pharmaceuticals sector based on our view that valuations have become
attractive after a period of underperformance that was the result of both
political and research & development concerns. We established new positions in
Novartis AG and Sanofi-Aventis, both of which offer strong product pipelines
and good growth prospects. We also added to the food, beverage & tobacco and
capital goods sectors through the purchase of household & personal goods
manufacturer Unilever Plc, tobacco manufacturer British American Tobacco Plc,
industrial conglomerate Siemens AG and construction company CRH Plc.

These transactions were mostly funded by taking profits in telecommunications -
a sector that had underperformed for most of 2005 and then experienced
substantial earnings upgrades in the second half of 2006 as pricing remained
resilient and cost-cutting began to positively impact profitability.
Specifically, the Fund took profits in Teliasonera and reduced its position in
Telecom Italia SpA. Within the financials sector, the Fund made a timely exit
from U.K. bank HSBC Holdings Plc and Dutch bank/insurer ING Groep on concerns
that a downward sloping yield curve would impact profitability, which it did.
The proceeds from these sales were used to establish new positions in Spanish
bank Banco Santander Central Hispano SA, which we believe offers one of the
strongest growth stories in Europe through its exposure to Brazil and Mexico,
along with Societe Generale and Intesa San Paulo.


How would you characterize the Fund's position at the close of the period?

At the end of the period, the Fund was overweight in financials (most notably
banks, insurance companies and diversified financials), capital goods and
utilities. The most significant underweights held in the portfolio were in
media, information technology, hardware & equipment, consumer durables &
apparel and food retail. We maintain our strategy of investing in stocks that
we believe have relatively low valuations.

Business and consumer confidence continues to improve in Europe, pointing to
sustained momentum in economic growth during 2007. Encouragingly, growth has
been driven by improving trends in domestic demand as well as robust export
demand, which has resulted from lower unemployment and tighter labor markets,
especially in the laggard economies such as Germany and Italy. Though we have
seen an increase in interest rate hikes from central banks, the monetary
policy environment remains accommodative and the combination of inexpensive
credit, strong corporate earnings and attractive valuations should allow the
market to make progress against what may be a more challenging international
backdrop.

communicated to shareholders, new sales charge schedules came into effect at
the same time for certain of these classes.

The Fund has multiple classes of shares:

* 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.

* Institutional 1 Shares are not subject to any sales charge. Institutional 1
Shares bear no ongoing distribution or service fees and are available only to
shareholders of The Europe Fund, Inc. in connection with the reorganization
and for dividend and capital gain reinvestment. These shares automatically
converted to Institutional Shares on May 7, 2007. Prior to inception,
Institutional 1 Share performance results are those of Institutional Shares.

* 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 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 Institutional Shares (which have no
distribution or service fees) restated for 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 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
following tables 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 following example (which is
based on a hypothetical investment of $1,000 invested on November 1, 2006 and
held through April 30, 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 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.

Notes to Financial Statements (Unaudited)


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. These
un-audited financial statements reflect all adjustments, which are, in the
opinion of management, necessary to present a fair statement of the results
for the interim period. All such adjustments are of a normal, recurring
nature. 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 will not be 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 investments--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.

Options written and purchased are valued at the last sale price in the case of
exchange-traded options. 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. Obligations with remaining
maturities of 60 days or less are valued at amortized cost unless BlackRock
Advisors, LLC (the "Manager"), an indirect, wholly owned subsidiary of
BlackRock Inc., believes that this method no longer produces fair valuations.
Effective April 2, 2007, securities purchased with a maturity of greater than
60 days may be valued at amortized cost. 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.



BLACKROCK EUROFUND                                               APRIL 30, 2007



Notes to Financial Statements (continued)


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.

(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 trans-actions 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.

Notes to Financial Statements (continued)


(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.

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, FASB issued "Statement of Financial Accounting
Standards No. 159, The Fair Value Option for Financial Assets and Financial
Liabilities" ("FAS 159"), which 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.


2. Investment Advisory Agreement and Transactions with Affiliates:
The Investment Advisory Agreement between the Fund and the Manager became
effective on September 29, 2006. Prior to September 29, 2006, Merrill Lynch
Investment Managers, L.P. ("MLIM") was the Fund's manager. The general partner
of MLIM is Princeton Services, Inc. ("PSI"), an indirect, wholly owned
subsidiary of Merrill Lynch & Co. Inc. ("Merrill Lynch"), which is the limited
partner. The Fund has also entered into a 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 and The PNC
Financial Services Group, Inc. are the principal owners of BlackRock, Inc.

Notes to Financial Statements (continued)


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 sub-advisory agreements 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. Prior to September 29, 2006, MLIM had a Sub-
Advisory Agreement with Merrill Lynch Asset Management U.K. Limited, an
affiliate of MLIM.

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%                 --

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 and an affiliate of each of the Distributors,
provide shareholder servicing and distribution services to the Fund. The
ongoing service fee compensates the Distributors 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 each Distributor and MLPF&S for providing shareholder and
distribution-related services to Investor B, Investor C and Class R
shareholders.

For the six months ended April 30, 2007, FAMD and BDI earned underwriting
discounts and direct commissions and MLPF&S and BDI earned dealer concessions
on sales of the Fund's Institutional and Investor A Shares as follows:


                                   MLPF&S           FAMD            BDI

Investor A                        $48,481         $4,293           $787

sales charges of $323 relating to transactions in Investor B Shares.

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 six months ended April 30, 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.

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. Prior to September 29, 2006, BIM was
organized as Merrill Lynch Investment Managers, LLC ("MLIM, LLC"), an
affiliate of MLIM, and MLIM, LLC was the securities lending agent. 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 six months ended April 30, 2007, the Fund reimbursed the Manager
$7,880 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 directors of the Fund are officers and/or directors
of BlackRock, Inc. or its affiliates.

The Fund charges a 2% redemption fee on the proceeds (calculated at market
value) of a redemption (either by sale or exchange) of Fund shares (except
Institutional 1 Shares) made within 30 days of purchase or exchange. The
redemption fee is paid to the Fund and is intended to offset the trading
costs, market impact and other costs associated with short-term trading into
and out of the Fund.

The Fund charges a 2% redemption fee on redemptions of Institutional 1 Shares
made prior to May 7, 2006. The redemption fee is paid to the Fund and is
intended to offset the trading costs, market impact and other costs associated
with the redemption of Institutional 1 Shares. Institutional 1 Shares convert
to Institutional Shares on May 7, 2007.


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. In November 2006, the agreement was renewed for one year under
substantially the same terms. 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 six
months ended April 30, 2007.


6. Capital Loss Carryforward:
On October 31, 2006, the Fund had a net capital loss carryforward of
$12,347,525, of which $1,163,623 expires in 2008 and $11,183,902 expires in
2009. This amount will be available to offset like amounts of any future
taxable gains.


7. 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 beneficial interest 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, $141,913 of distributions in
excess of net realized gains and $8,113,020 of net unrealized appreciation
were combined with those of the Fund. The aggregate net assets immediately
after the acquisition amounted to $1,125,904,035.
