A Letter From the President

Dear Shareholder

Financial markets faced a number of crosscurrents over the past several months,
but most major benchmarks managed to post positive returns for the annual and
semi-annual reporting periods ended April 30, 2005:



Total Returns as of April 30, 2005                              6-month    12-month

After expanding at an annualized rate of 4.4% in 2004, U.S. gross domestic
product growth for the first quarter of 2005 came in at an estimated 3.1%
(although that figure was later revised upward to 3.5%). Nevertheless, the
Federal Reserve Board continued increasing interest rates at a measured pace to
combat emergent inflation. The most recent hike came on May 3, and brought the
federal funds rate to 3%. Recently, signs of inflation have taken the form of
rising business costs and increasing consumer prices, particularly in the areas
of gasoline, healthcare, housing and education.

U.S. equities ended 2004 in a strong rally, but stumbled into negative territory
in 2005. The market weakness was largely fueled by the potential for slowing
economic and corporate earnings growth, renewed energy price concerns and a lack
of investor conviction. On the positive side, certain sectors of the market have
been performing well (particularly energy) and corporate transactions, such as
mergers and acquisitions, stock buy-backs and dividend payouts, have all
increased. International equities, especially in Asia, have benefited from
higher economic growth rates.

In the bond market, we witnessed a yield curve flattening trend over the past
several months as short-term yields increased and longer-term interest rates
remained more stable or fell. At the end of April 2005, the two-year Treasury
note yielded 3.66% and the 10-year Treasury note yielded 4.21%, a difference of
55 basis points (.55%). This compared to a spread of 149 basis points six months
earlier and 222 basis points 12 months ago.

Looking ahead, the environment is likely to be a challenging one for investors.
With this in mind, we encourage you to meet with your financial advisor to
review your goals and asset allocation and to rebalance your portfolio, as
necessary, to ensure it remains aligned with your objectives and risk tolerance.
As always, we thank you for trusting Merrill Lynch Investment Managers with your
investment assets, and we look forward to serving you in the months and years
ahead.

                                 Sincerely,


                                 /s/ Robert C. Doll, Jr.

A Discussion With Your Fund's Portfolio Manager

      The Fund significantly outperformed both its benchmark and its comparable
Lipper category average for the period, benefiting primarily from successful
stock selection across various industry sectors.

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

For the six-month period ended April 30, 2005, the Fund's Class A, Class B,
Class C, Class I and Class R Shares had total returns of +8.04%, +7.61%, +7.69%,
+8.15% and +7.93%, 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.) These
results compare quite favorably to the +6.72% return of the Fund's unmanaged
benchmark, the Russell 1000 Value Index, for the same period. In addition, the
Fund significantly outperformed its comparable Lipper category of Multi-Cap
Value Funds, which posted an average return of +5.15% for the six-month period.
(Funds in this Lipper category invest in a variety of market capitalization
ranges without concentrating 75% of their equity assets in any one market
capitalization range over an extended period of time. Multi-Cap Value funds
typically have a below-average price-to-earnings ratio, price-to-book ratio and
three-year sales-per-growth value compared to the S&P SuperComposite 1500
Index.)

The Fund invests primarily in a diversified portfolio of large cap companies
selected from securities found in the Russell 1000 Index. Stock selection in the
health care sector (particularly health care providers and services) and
financials (particularly insurance) benefited Fund performance. In the energy
sector, the combination of a sector overweight and effective stock selection
enhanced returns, although this was somewhat offset by the negative impact of
our underweight position in Exxon Mobil Corp. Detracting from performance versus
the benchmark was our relative weighting and security selection in the
technology and consumer staples sectors.

At the individual stock level, the largest positive contributors to performance
during the six-month period were Humana, Inc., PacifiCare Health Systems, Valero
Energy Corp. and Cigna Corp. For the most part, we retained our positions in
these strong performers, although we do typically take some marginal profits in
select stocks that appreciate significantly. This allows us to maintain our
desired relative weightings in any individual stock and/or sector. Also
benefiting Fund performance were our underweight positions in JPMorgan Chase &
Co., Verizon Communications Inc. and International Business Machines Corp.

Hindering relative performance somewhat was an underweight position in Altria
Group. The largest individual detractors included Dynegy, Inc., Claire's Stores,
Inc. and Eastman Kodak Co. Each of these stocks disappointed during the period
as company fundamentals developed unfavorably and, in general, contrary to our
expectations. As part of our overall investment strategy, we eliminated or
reduced the detractors to make room in the portfolio for stocks with more
promising investment cases.

Because the Fund invests in large-capitalization stocks that represent a
significant part of the U.S. stock market, its portfolio was influenced by the
same economic and market events that affected the broader stock market during
the period. Over the past six months, the markets reacted to positive and
negative economic news, as well as national and international events, such as
the conclusion of the U.S. presidential election and the ongoing war and
elections in Iraq. The major indexes posted impressive returns in the fourth
quarter of 2004, although these gains were largely given back in the new year as
concerns grew over inflation, record-high oil prices, the weakening of the U.S.
dollar and the threat of continuing interest rate hikes. Under these conditions,
large-capitalization shares were favored by investors. Notably, value stocks
outperformed during the period. For the six months ended April 30, 2005, the
Russell 1000 Value Index's return of +6.72% far outpaced the +1.14% return of
the Russell 1000 Growth Index. An advanced estimate of first quarter 2005 gross
domestic product (GDP) growth came in unexpectedly low at 3.1%, although that
figure was later revised upward to 3.5%. However, throughout this challenging
environment, solid growth in corporate profits was recorded, and the housing
market continued at a strong pace.

The recent correction in the broad markets--and cyclical stocks in particular --
reflects both general concerns over the slowing of economic growth and specific
concerns regarding the impact of tighter monetary policy, higher energy prices,
currency market volatility and credit market risks. Amid these conditions, we
are pleased with the Fund's ability to outperform its benchmark and its peers.


4       MERRILL LYNCH LARGE CAP VALUE FUND      APRIL 30, 2005


What changes were made to the Portfolio during the period?

We maintained a procyclical bias throughout the period. Through our bottom-up
stock selection process, we continued to identify stocks with favorable growth
characteristics and earnings developments, selling at attractive relative
valuations. As a result of this process, we increased our positions relative to
the benchmark in the information technology, energy and health care sectors. We
reduced our positions in the consumer discretionary, industrials, utilities,
consumer staples and materials sectors, although the Portfolio remained
overweight in materials at period-end.

The largest purchases during the period included Exxon Mobil Corp.,
Hewlett-Packard Co., Lehman Brothers Holdings, Inc. and Unocal Corp. The largest
sales included McDonald's Corp., WellPoint, Inc., Countrywide Financial Corp.
and Costco Wholesale Corp. These transactions reflected our ongoing refinement
of the portfolio, as we continue to look for stocks that best meet our
investment criteria while pruning those that have deteriorated versus our
original assessment.

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

The Portfolio's largest overweights as of April 30, 2005 were in information
technology, which we believe should benefit from strong earnings growth, as well
as energy, health care and materials. The largest underweights were in
financials, which tend to underperform in periods of rising interest rates,
telecommunications services, consumer staples, industrials and utilities.

Companies exhibiting good earnings momentum, earnings surprise and valuation
characteristics continue to deliver strong performance, and we remain committed
to these disciplines for stock selection. The Portfolio remains positioned in
cyclical stocks, which should benefit amid favorable economic conditions.
Despite softer first quarter GDP growth and some recent rumblings of an economic
slowdown, we believe the current environment is still generally supportive of
equities. Having said that, we continue to believe that a highly diversified
portfolio and a focus on individual security selection (rather than a more macro
approach) is appropriate and should be rewarded on a relative basis.

Performance Data

About Fund Performance

Investors are able to purchase shares of the Fund through multiple pricing
alternatives:

o     Class A Shares incur a maximum initial sales charge (front-end load) of
      5.25% and an account maintenance fee of 0.25% per year (but no
      distribution fee).

o     Class B Shares are subject to a maximum contingent deferred sales charge
      of 4% declining to 0% after six years. All Class B Shares purchased prior
      to June 1, 2001 will maintain the four-year schedule. In addition, Class B
      Shares are subject to a distribution fee of 0.75% per year and an account
      maintenance fee of 0.25% per year. These shares automatically convert to
      Class 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     Class C Shares are subject to a distribution fee of 0.75% per year and an
      account maintenance fee of 0.25% per year. In addition, Class C Shares are
      subject to a 1% contingent deferred sales charge if redeemed within one
      year of purchase.

o     Class I Shares incur a maximum initial sales charge (front-end load) of
      5.25% and bear no ongoing distribution or account maintenance fees. Class
      I Shares are available only to eligible investors.

o     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 an account maintenance 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 Class I Shares (which have
      no distribution or account maintenance fees) restated for Class R Share
      fees.

None of the past results shown should be considered a representation of future
performance. Current performance may be lower or higher than the performance
data quoted. Refer to www.mlim.ml.com to obtain performance data current to the
most recent month-end. Performance results do not reflect the deduction of taxes
that a shareholder would pay on fund distributions or the redemption of fund
shares. Figures shown in each of the following tables assume reinvestment of all
dividends and capital gain distributions, if any, at net asset value on the
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 account maintenance, 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
12(b)-1 fees, and other Fund expenses. The following example (which is based on
a hypothetical investment of $1,000 invested on November 1, 2004 and held
through April 30, 2005) 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

*     For each class of the Fund, expenses are equal to the annualized expense
      ratio for the class (1.22% for Class A, 1.99% for Class B, 1.99% for Class
      C, .97% for Class I and 1.47% 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 fund 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.

16      MERRILL LYNCH LARGE CAP VALUE FUND      APRIL 30, 2005


Notes to Financial Statements                 Merrill Lynch Large Cap Value Fund

1. Significant Accounting Policies:

Merrill Lynch Large Cap Value Fund of Merrill Lynch Large Cap Series Funds, Inc.
(the "Fund") is registered under the Investment Company Act of 1940, as amended,
as a diversified, open-end investment company. The Fund seeks to achieve its
investment objective by investing all of its assets in Master Large Cap Value
Portfolio (the "Portfolio"), which is a portfolio of Master Large Cap Series
Trust that 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 April 30, 2005 was
100%. The Fund offers multiple classes of shares. Shares of Class A and Class I
are sold with a front-end sales charge. Shares of Class B and Class C may be
subject to a contingent deferred sales charge. Class 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
Class A, Class B, Class C and Class R Shares bear certain expenses related to
the account maintenance of such shares, and Class B, Class 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
account maintenance and distribution expenditures (except that Class B
shareholders may vote on certain changes to the Class 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 its shareholders.
Therefore, no federal income tax provision is required. Under the applicable
foreign tax law, withholding taxes may be imposed on interest, dividends and
capital gains at various rates.

(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.

2. Transactions with Affiliates:

The Fund has entered into an Administration Agreement with Fund Asset
Management, L.P. ("FAM"). The general partner of FAM is Princeton Services, Inc.
("PSI"), an indirect, wholly-owned subsidiary of Merrill Lynch & Co., Inc. ("ML
& Co."), which is the limited partner. The Fund pays a monthly fee at an annual
rate of .25% 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.

The Fund has also entered into a Distribution Agreement and Distribution Plan
with FAM Distributors, Inc. ("FAMD" or the "Distributor"), which is a
wholly-owned subsidiary of Merrill Lynch Group, Inc.

Notes to Financial Statements (continued)     Merrill Lynch Large Cap Value Fund

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 account maintenance 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:

- --------------------------------------------------------------------------------
                                                  Account           Distribution
                                               Maintenance Fee          Fee

Class R ................................            .25%                .25%
- --------------------------------------------------------------------------------

Pursuant to a sub-agreement with the Distributor, Merrill Lynch, Pierce, Fenner
& Smith Incorporated ("MLPF&S"), an affiliate of FAM, also provides account
maintenance and distribution services to the Fund. The ongoing account
maintenance fee compensates the Distributor and MLPF&S for providing account
maintenance services to Class A, Class B, Class C and Class R shareholders. The
ongoing distribution fee compensates the Distributor and MLPF&S for providing
shareholder and distribution-related services to Class B, Class C and Class R
shareholders.

For the six months ended April 30, 2005, FAMD earned underwriting discounts and
MLPF&S earned dealer concessions on sales of the Fund's Class A and Class I
Shares as follows:

- --------------------------------------------------------------------------------
                                                    FAMD                 MLPF&S
- --------------------------------------------------------------------------------

Class I ............................              $    160              $  2,646

For the six months ended April 30, 2005, MLPF&S received contingent deferred
sales charges of $91,371 and $13,735 relating to transactions in Class B and
Class C Shares, respectively.

Financial Data Services, Inc. ("FDS"), an indirect, wholly-owned subsidiary of
ML & Co., is the Fund's transfer agent.

Certain officers and/or directors of the Fund are officers and/or directors of
FAM, FAMD, PSI, FDS, and/or ML & Co.

Notes to Financial Statements                   Master Large Cap Value Portfolio

1. Significant Accounting Policies:

Master Large Cap Value Portfolio (the "Portfolio") is part of Master Large Cap
Series 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 Portfolio, 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 National 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 Small Cap
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 are valued at the last sale price in the case of exchange-traded
options or, in the case of options traded in the OTC market, the last ask price.
Options purchased are valued at their last sale price in the case of
exchange-traded options or, in the case of options traded in the OTC market, the
last bid price. Swap agreements are valued daily based upon quotations from
market makers. 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 the Investment Adviser believes that this method no
longer produces fair valuations.

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
and money market instruments, 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's shares are determined as of such times. Foreign currency exchange
rates also are generally determined prior to 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 may be valued
at their fair value as determined in good faith by the Trust's Board of Trustees
or by the Investment Adviser 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.

Notes to Financial Statements (continued)       Master Large Cap Value Portfolio

o     Financial futures contracts--The Portfolio may purchase or sell financial
      futures contracts and options on such futures contracts. Futures contracts
      are contracts for delayed delivery of securities at a specific date and at
      a specific price or yield. Upon entering 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 over-the-counter 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.

(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. 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 receives 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 any time and the borrower, after notice,
is required to return borrowed securities within five business days. The
Portfolio may pay reasonable finders, 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) Custodian bank--The Portfolio recorded an amount payable to the custodian
bank reflecting an overnight overdraft, which resulted from management estimates
of available cash.

2. Investment Advisory Agreement and Transactions with Affiliates:

The Trust has entered into an Investment Advisory Agreement with Fund Asset
Management, L.P. ("FAM"). The general partner of FAM is Princeton Services, Inc.
("PSI"), an indirect, wholly-owned subsidiary of Merrill Lynch & Co., Inc.
("ML & Co."), which is the limited partner.

FAM 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 .50% of the average daily
value of the Portfolio's net assets. FAM has entered into a Sub-Advisory
Agreement with Merrill Lynch Asset Management U.K. Limited ("MLAM U.K."), an
affiliate of FAM, pursuant to which MLAM U.K. provides investment advisory
services to FAM with respect to the Portfolio. There is no increase in the
aggregate fees paid by the Portfolio for these services.

The Portfolio 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"), an affiliate of FAM, or its affiliates.
As of April 30, 2005, the Portfolio lent securities with a value of $11,547,294
to MLPF&S or its affiliates. Pursuant to that order, the Portfolio also has
retained Merrill Lynch Investment Managers, LLC ("MLIM, LLC"), an affiliate of
FAM, as the securities lending agent for a fee based on a share of the returns
on investment of cash collateral. MLIM, LLC 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 MLIM, LLC or in registered
money market Portfolios advised by FAM or its affiliates. For the six months
ended April 30, 2005, MLIM, LLC received $5,234 in securities lending agent
fees.

For the six months ended April 30, 2005, the Portfolio reimbursed FAM $10,724
for certain accounting services.

Certain officers and/or trustees of the Trust are officers and/or directors of
FAM, PSI, MLAM U.K., and/or ML & Co.

3. Investments:

Purchases and sales of investments, excluding short-term securities, for the six
months ended April 30, 2005 were $630,181,714 and $440,822,540, respectively.

4. Short-Term Borrowings:

The Portfolio, along with certain other funds managed by FAM and its affiliates,
is a party to a $500,000,000 credit agreement with a group of lenders. 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. The Portfolio pays a commitment fee of .07% 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 Portfolio's election, the federal funds rate plus .50% or a
base rate as defined in the credit agreement. The Portfolio did not borrow under
the credit agreement during the six months ended April 30, 2005. On November 26,
2004, the credit agreement was renewed for one year under substantially the same
terms.
