A Letter to Shareholders

Dear Shareholder

For most financial markets, 2007 opened just as 2006 ended -- on a positive
trajectory. At the end of February and into March, however, 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 several concerns, notably a weakening economy, some disappointing
corporate earnings announcements, escalating geopolitical concerns in the Middle
East and increasing delinquencies in the subprime mortgage market. Despite the
recent spate of volatility, underlying stock market fundamentals appear quite
sound, supported by a generally favorable global economic backdrop, tame
inflation, relatively low interest rates and attractive valuations.

Not unlike the equity market, the bond market also has seen volatility recently
as observers have attempted to interpret mixed economic signals. A bond market
rally late last year reversed itself early in 2007 as economic data
strengthened. Prices improved (and yields fell) again in February as equities
struggled, but retrenched slightly in March. Notably, the Treasury curve
remained inverted for much of 2006 and into 2007. The 30-year Treasury yield
stood at 4.84% at the end of March 2007, while the one-month Treasury offered
the highest yield on the curve at 5.07%.

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. Although the central bankers continue to express
concern about potential inflationary pressures, they also have made reference to
signs of economic weakness in their public statements. Most observers expect the
Fed to keep interest rates on hold for now.

Notwithstanding some recent volatility, most major market indexes managed to
post positive returns for the annual and semi-annual reporting periods ended
March 31, 2007:

If recent market movements are any guide, 2007 could be a year of enhanced

the markets, please ask your financial professional for the latest issue of

A Discussion With Your Fund's Portfolio Manager

      We continued to diversify the Fund geographically while also reducing
exposure to more interest-rate-sensitive subsectors within the financials
industry.

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

For the six-month period ended March 31, 2007, BlackRock Global Financial
Services Fund, Inc.'s Institutional, Investor A, Investor B, Investor C and
Class R Shares had total returns of +8.68%, +8.53%, +8.18%, +8.07% and +8.36%,
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 and 7 of this report to shareholders.) The Fund's results were
competitive with the +8.39% return of the Morgan Stanley Capital International
(MSCI) World Financials Index, but lagged the +11.07% return of the MSCI World
Index for the six-month period, as the financials sector was the third-worst
performer in the broader index.

During the six-month period, the main driver of Fund performance was an
allocation to options on positions in The Goldman Sachs Group, Inc. and The Bear
Stearns Cos., Inc. within the capital markets subsector. This strategy added
over 300 basis points (3%) to performance relative to the MSCI World Financials
Index. An underweight position and strong stock selection in commercial banks
also contributed positively to performance, led by shares of Shinhan Financial
Group Co. Ltd., Kookmin Bank, Mitsubishi UFJ Financial Group, Inc. and Hana
Financial Holdings. On an absolute basis, the insurance subsector contributed
180 basis points to Fund performance, while the real estate management &
development subsector added over 150 basis points for the semi-annual period.

The Fund's exposure to real estate investment trusts (REITs) and thrifts &
mortgage finance weighed on relative returns given the continued weakness in the
U.S. housing market. Stock selection in diversified financial services also
detracted somewhat from performance relative to the benchmark financials index.

What changes were made to the Portfolio during the period?

We continued the repositioning that was started near the end of the last fiscal
year with the intention of further risk reduction and geographic diversification
within the Portfolio. We increased our commercial bank exposure, primarily in
Europe and Asia, with new positions in Shinhan Financial Group, Banco Santander
Central Hispano SA, Kookmin Bank, Sumitomo Mitsui Financial Group, Inc., BNP
Paribas SA and Mitsubishi UFJ Financial Group. The Portfolio's exposure to
capital markets also was increased with the addition of asset management
companies Julius Baer Holdings AG and Franklin Resources, Inc.

The Portfolio's allocation to the thrifts & mortgage finance subsector was
increased with new positions in Fannie Mae and Countrywide Financial Corp.,
although the Portfolio no longer has exposure to the troubled monoline subprime
mortgage companies, such as New Century Mortgage Corp., Accredited Mortgage
Corp. and Fremont General Corp., all of which were sold last year. Having said
that, Countrywide Financial does some subprime originations (generally around 8%
- - 10% of originations) in its mortgage bank, which represent about one-half of
earnings. Securities firms in the Portfolio, such as Lehman Brothers and Bear
Stearns, also originate, securitize and trade subprime mortgages and securities
as part of their well-diversified business mix.

The Portfolio's exposure to the real estate management & development subsector
was increased slightly, primarily in China/Hong Kong, where we believe the
property development sector is attractive despite attempts by the government to
slow housing appreciation. We significantly reduced the Portfolio's exposure to
mortgage REITs. Insurance sector exposure also was reduced, although we did
initiate a new position in AXA SA. Finally, we took profits on our Goldman Sachs
options prior to the downturn in capital markets performance near the middle of
the period.

From a geographic standpoint, we increased the Portfolio's exposure to Europe
and Asia, while reducing exposure to the United States. In Europe, we added to
commercial banks with new positions in Banco Santander Central Hispano SA, BNP
Paribas SA, Erste Bank der Oesterreichischen Sparkassen AG and increased our
existing holding in Barclays Plc. Likewise, we added to our European insurance
weighting with the aforementioned position in AXA, and to asset management
companies with the aforementioned new position in Julius Baer Holding. We added
to positions in Europe for some time with the intent of further diversifying the
Portfolio's portfolio. In our view, an underweight position in Europe is not
warranted given the up-tick in growth we have seen there. We believe growth in
Europe should be at least as good as in the United States, if not better. In
addition, we do not expect


4       BLACKROCK GLOBAL FINANCIAL SERVICES FUND, INC.       MARCH 31, 2007


margin compression to be as difficult as it could be in the United States. We
anticipate loan growth and deposit growth that is better than we have seen in
the United States, with better net interest margins. We also see more growth
opportunities in consumer lending in Europe.

In Asia, we have been adding to the Portfolio's positions in commercial banks in
Japan and South Korea. In Japan, we believe further interest rate increases this
year, which are still possible, would be good for that nation's banks. The
Portfolio's overweight position in South Korean banks and insurance companies,
while materially reduced, remains significant, as we continue to see value in
their combination of high profitability, high growth and relatively low
valuations. In our view, the valuations and business prospects of these
companies remain more attractive than most alternatives in both developed and
emerging markets, especially since it presently appears that South Korea's
central bank is done raising interest rates. The Portfolio's reduced exposure to
the United States has funded our repositioning elsewhere in the world.

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

The Portfolio ended the period underweight in commercial banks, primarily in the
United States. This reflects our negligible exposure to regional or community
banks, which are more susceptible to interest rate movements or inversions of
the yield curve. Most of the commercial bank exposure in the Portfolio is
overseas. The Portfolio ended the period overweight in securities firms,
diversified financial services with large capital markets businesses, and
insurance. We believe the diversified financial services companies are not as
tied to interest rate changes because many of them have large capital markets
businesses. We also believe the diversified financial services and insurance
sectors are undervalued versus other opportunities in the financials sector.
Additionally, the Portfolio ended the period overweight in real estate
management & development, based on our belief that the property development
sector in China and Hong Kong is attractive. The Portfolio had an underweight
position at period-end in the mortgage REIT sector given the continued weakness
in the United States housing market. The Portfolio's commitment to stocks
outside of the financial sector has been almost entirely eliminated.

From a geographic standpoint, the Portfolio ended the period overweight in Asia
ex-Japan, primarily due to the South Korean overweight. The Portfolio had a
neutral weighting in Japan compared to the MSCI World Financials Index and was
underweight in Europe, although much less so than at the beginning of the
period. We do not want to be materially underweight in Europe, as we prefer the
opportunities we are seeing there. Having said that, it will take time to
significantly change the Portfolio's weighting in Europe, as we are being
selective in our stock-selection process. We will continue to move money out of
the United States and into Europe and Asia as we continue to research
opportunities to diversify the portfolio geographically.

Finally, in our view, larger cap financial stocks still appear to be undervalued
and more attractive than their small- to mid-cap counterparts and, as such,
should experience good earnings growth and multiple expansion going forward.

Performance Data

About Fund Performance

Effective October 2, 2006, the Fund's Class A, Class B, Class C and Class I
Shares were redesignated Investor A, Investor B, Investor C and Institutional
Shares, respectively. Class R Shares did not change their designation. As
previously 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:

o     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.

o     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).

o     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.

o     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.

o     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 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 October 1, 2006 and held through
March 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 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 (1.42% for Institutional, 1.67% for Investor A, 2.43%
      for Investor B, 2.44% for Investor C and 1.93% for Class R), multiplied by
      the average account value over the period, multiplied by 182/365 (to
      reflect the one-half year period shown). Because the Fund is a feeder
      fund, the expense table example reflects the expenses of both the feeder
      fund and the master portfolio in which it invests.
**    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 (Unaudited)
                                  BlackRock Global Financial Services Fund, Inc.

1. Significant Accounting Policies:

BlackRock Global Financial Services Fund, Inc. (the "Fund") is registered under
the Investment Company Act of 1940, as amended, as a diversified, open-end
management investment company. The Fund seeks to achieve its investment
objective by investing all of its assets in Global Financial Services Portfolio
(the "Portfolio") of Global Financial Services Master Trust, which has the same
investment objective and strategies as the Fund. The value of the Fund's
investment in the Portfolio reflects the Fund's proportionate interest in the
net assets of the Portfolio. The performance of the Fund is directly affected by
the performance of the Portfolio. The financial statements of the Portfolio,
including the Schedule of Investments, are included elsewhere in this report and
should be read in conjunction with the Fund's financial statements. 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 unaudited
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 percentage
of the Portfolio owned by the Fund at March 31, 2007 was 100%. The Fund offers
multiple classes of shares. Effective October 2, 2006, Class I, Class A, Class B
and Class C Shares were redesignated Institutional, Investor A, Investor B and
Investor C Shares, respectively. Class R Shares did not change their
designation. Institutional Shares are sold only to certain eligible investors.
Investor A Shares are sold with a front-end sales charge. Shares of Investor B
and Investor C Shares may be subject to a contingent deferred sales charge.
Class R Shares are sold only to certain retirement plans. 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 -- The Fund records its investment in the Portfolio
at fair value. Valuation of securities held by the Portfolio is discussed in
Note 1(a) of the Portfolio's Notes to Financial Statements, which are included
elsewhere in this report.

(b) Investment income and expenses -- The Fund records daily its proportionate
share of the Portfolio's income, expenses and realized and unrealized gains and
losses. In addition, the Fund accrues its own expenses.

(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 shareholders. Therefore,
no federal income tax provision is required.

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

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

(f) Investment transactions -- Investment transactions in the Portfolio are
accounted for on a trade date basis.

(g) 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. Transactions with Affiliates:

The Investment Advisory Agreement between the Trust, on behalf of the Fund, and
BlackRock Advisors, LLC (the "Manager"), an indirect, wholly owned subsidiary of
BlackRock, Inc., became effective on September 29, 2006. Prior to September 29,
2006, Fund Asset Management, L.P. ("FAM") was the Trust's manager. The general
partner of FAM is Princeton Services, Inc. ("PSI"), an indirect, wholly owned
subsidiary of Merrill Lynch & Co., Inc. ("Merrill Lynch"), which is the limited
partner. Merrill Lynch and The PNC Financial Services Group, Inc. are the
principal owners of BlackRock, Inc.

The Fund has entered into an Administration Agreement with the Manager. The Fund
pays a monthly fee at an annual rate of .35% of the Fund's average daily net
assets for the performance of administrative services (other than investment
advice and related portfolio activities) necessary for the operation of the
Fund. Prior to September 29, 2006, FAM acted as the Fund's administrator and was
compensated at the same fee rate.

The Fund has also entered into separate Distribution Agreements and Distribution
Plans with FAM Distributors, Inc. ("FAMD") and BlackRock Distributors, Inc.
("BDI"), collectively, the "Distributor." FAMD is a wholly owned subsidiary of
Merrill Lynch Group, Inc. and BDI is an affiliate of BlackRock, Inc.

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
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:

- --------------------------------------------------------------------------------
                                                                    Distribution
                                                    Service 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, and an affiliate of each Distributor, provides
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 each Distributor and
MLPF&S for providing shareholder services and distribution-related services to
Investor B, Investor C and Class R shareholders.

For the six months ended March 31, 2007, FAMD and BDI earned underwriting
discounts and MLPF&S earned dealer concessions on sales of the Fund's Investor A
Shares as follows:

- --------------------------------------------------------------------------------
                                            FAMD            MLPF&S           BDI
- --------------------------------------------------------------------------------
Investor A ..........................      $1,140          $11,692          $504
- --------------------------------------------------------------------------------

For the six months ended March 31, 2007, MLPF&S received contingent deferred
sales charges of $4,319 and $2,668 relating to transactions in Investor B and
Investor C Shares, respectively.

Furthermore, MLPF&S received contingent deferred sales charges of $2,182
relating to transactions subject to front-end sales charge waivers in Class A.

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. During the six months
ended March 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.

Notes to Financial Statements (Unaudited)    Global Financial Services Portfolio

1. Significant Accounting Policies:

Global Financial Services Portfolio (the "Portfolio") is part of Global
Financial Services Master Trust (the "Trust"). The Trust is registered under the
Investment Company Act of 1940, as amended, and is organized as a Delaware
statutory trust. The Declaration of Trust permits the Trustees to issue
nontransferable interests in the Trust, subject to certain limitations. The
Portfolio'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 unaudited
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 following is
a summary of significant accounting policies followed by the Portfolio.

(a) Valuation of investments -- Equity securities that are held by the Portfolio
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 Trust.
Long positions traded in the over-the-counter ("OTC") market, 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 Trust. Short positions traded in the OTC market are
valued at the last available asked price. Portfolio securities that are traded
both in the OTC market and on a stock exchange are valued according to the
broadest and most representative market.

Options written or 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
Portfolio 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 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 Portfolio
employs pricing services to provide certain securities prices for the Portfolio.
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 Trust, including valuations furnished by the
pricing services retained by the Portfolio, which may use a matrix system for
valuations. The procedures of a pricing service and its valuations are reviewed
by the officers of the Portfolio under the general supervision of the Trust's
Board of Trustees. Such valuations and procedures will be reviewed periodically
by the Board of Trustees of the Trust.

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 assets of the Portfolio 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 Portfolio's net assets. 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 Trust's
Board of Trustees or by BlackRock Advisors, LLC (the "Manager"), an indirect
wholly owned subsidiary of BlackRock, Inc., using a pricing service and/or
procedures approved by the Trust's Board of Trustees.

(b) Derivative financial instruments -- The Portfolio may engage in various
portfolio investment strategies, both to increase the return of the Portfolio,
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 Portfolio 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


    BLACKROCK GLOBAL FINANCIAL SERVICES FUND, INC.       MARCH 31, 2007       29


Notes to Financial Statements (continued)    Global Financial Services Portfolio

into a contract, the Portfolio deposits, and maintains as collateral, such
initial margin as required by the exchange on which the transaction is effected.
Pursuant to the contract, the Portfolio 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 Portfolio as unrealized gains or losses. When the contract is
closed, the Portfolio 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     Options -- The Portfolio may purchase and write call and put options. When
      the Portfolio writes an option, an amount equal to the premium received by
      the Portfolio 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 Portfolio enters into a closing
      transaction), the Portfolio realizes a gain or loss on the option to the
      extent of the premiums received or paid (or a gain or loss to the extent
      that the cost of the closing transaction exceeds the premium paid or
      received).

      Written and purchased options are non-income producing investments.

o     Forward foreign exchange contracts -- The Portfolio 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 Portfolio as an unrealized gain
      or loss. When the contract is closed, the Portfolio 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.

o     Foreign currency options and futures -- The Portfolio 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 Portfolio, sold by the Portfolio but not yet
      delivered, or committed or anticipated to be purchased by the Portfolio.

(c) 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 Portfolio 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.

(d) Income taxes -- The Portfolio is considered as a "pass-through" entity for
federal income tax purposes. As such, each investor in the Portfolio is treated
as owner of its proportionate share of the net assets, income, expenses and
realized and unrealized gains and losses of the Portfolio. 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. It is intended that the Portfolio's assets will be managed so an
investor in the Portfolio can satisfy the requirements of Subchapter M of the
Internal Revenue Code.

(e) Security transactions and investment income -- Security transactions are
accounted for on the date the securities are purchased or sold (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 portfolio has determined the ex-dividend date.
Interest income is recognized on the accrual basis.

(f) Securities lending -- The Portfolio 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 Portfolio and any additional required collateral is delivered to the
Portfolio on the next business day. Where the Portfolio receives securities as
collateral for the loaned securities, it collects a fee from the borrower. The
Portfolio typically receives the income on the loaned securities but does not
receive the income on the collateral. Where the Portfolio 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


30       BLACKROCK GLOBAL FINANCIAL SERVICES FUND, INC.       MARCH 31, 2007


Notes to Financial Statements (continued)    Global Financial Services Portfolio

any time and the borrower, after notice, is required to return borrowed
securities within five business days. The Portfolio 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 Portfolio could
experience delays and costs in gaining access to the collateral. The Portfolio
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.

(g) 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 Portfolio'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 Portfolio'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 Portfolio's financial
statements, if any, has not been determined.

2. Investment Advisory Agreement and Transactions with Affiliates:

The Investment Advisory Agreement between the Trust and the Manager became
effective on September 29, 2006. Prior to September 29, 2006, Fund Asset
Management, L.P. ("FAM") was the Trust's manager. The general partner of FAM is
Princeton Services, Inc. ("PSI"), an indirect, wholly owned subsidiary of
Merrill Lynch & Co., Inc. ("Merrill Lynch"), which is the limited partner.
Merrill Lynch and The PNC Financial Services Group, Inc. are the principal
owners of BlackRock, Inc.

The Manager is responsible for the management of the Portfolio's investments and
provides the necessary personnel, facilities, equipment and certain other
services necessary to the operations of the Portfolio. For such services, the
Portfolio pays a monthly fee at an annual rate of .40% of the average daily
value of the Portfolio'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
Portfolio to the Manager. Prior to September 29, 2006, FAM had a Sub-Advisory
Agreement with Merrill Lynch Asset Management U.K. Limited ("MLAM U.K."), an
affiliate of FAM.

The Trust has received an exemptive order from the Securities and Exchange
Commission permitting it to lend portfolio securities to Merrill Lynch, Pierce,
Fenner & Smith Incorporated ("MLPF&S"), a wholly owned subsidiary of Merrill
Lynch, or its affiliates. Pursuant to that order, the Portfolio has retained BIM
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 FAM, and
MLIM, LLC was the securities lending agent. BIM may, on behalf of the Portfolio,
invest cash collateral received by the Portfolio for such loans, among other
things, in a private investment company managed by the Manager or in


    BLACKROCK GLOBAL FINANCIAL SERVICES FUND, INC.       MARCH 31, 2007       31


Notes to Financial Statements (concluded)    Global Financial Services Portfolio

registered money market funds advised by the Manager or its affiliates. For the
six months ended March 31, 2007, BIM received $3,301 in securities lending agent
fees.

In addition, MLPF&S received $5,665 in commissions on the execution of portfolio
security transactions for the Portfolio for the six months ended March 31, 2007.

For the six months ended March 31, 2007, the Portfolio reimbursed the Manager
$864 for certain accounting services.

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

3. Investments:

Purchases and sales of investments, for the six months ended March 31, 2007 were
$28,907,000 and $30,520,564, respectively.

4. Short-Term Borrowings:

The Portfolio, 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. The Portfolio may borrow under the credit agreement to fund shareholder
redemptions and for other lawful purposes other than for leverage. The Portfolio
may borrow up to the maximum amount allowable under the Portfolio's current
prospectus and statement of additional information, subject to various other
legal, regulatory or contractual limits. On November 22, 2006, the credit
agreement was renewed for one year under substantially the same terms. The
Portfolio pays a commitment fee of .06% per annum based on the Portfolio'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 Portfolio did not borrow under the credit agreement during the
six months ended March 31, 2007.
