                              Merrill Lynch Large Cap Value Fund, April 30, 2003

DEAR SHAREHOLDER

Effective April 14, 2003, the share class names for the Merrill Lynch family of
mutual funds were changed to be consistent with the standard share classes of
most other mutual fund families. As of that date, all Class A Shares were
redesignated Class I Shares. At the same time, Class D Shares were redesignated
Class A Shares. There are no changes to the Class B or Class C share class
labels. Trading symbols have not changed nor have current eligibility rules or
pricing structures. This redesignation of share classes does not impact your
investment in any way.

Merrill Lynch Large Cap Value Fund invests primarily in a diversified portfolio
of equity securities of large cap companies that Fund management selects from
among the securities found in the Russell 1000 Value Index. Our investment
process attempts to add value through both security selection and portfolio
construction. Security selection involves the use of quantitative selection
criteria including earnings momentum, earnings surprise and valuation. These
criteria are input into a proprietary quantitative model and are subject to
selective fundamental overrides. Portfolio construction consists of an
optimization process with risk management controlling style, capitalization,
sector and individual security selection.

Fund Performance

For the six months ended April 30, 2003, the Fund's Class A, Class B, Class C
and Class I Shares had total returns of +1.38%, +1.01%, +1.01% and + 1.47%,
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 4 and 5 of this report to shareholders.) The Fund's results were
below the +5.25% total return of the benchmark, the unmanaged Russell 1000 Value
Index for the same six-month period.

The past six months have been challenging. While we generated positive absolute
performance, our relative performance trailed the benchmark. Overall, most of
the underperformance was attributable to stock selection, particularly in
information technology and consumer discretionary. In addition, the Portfolio's
underweight in energy had a negative impact on performance. On the positive
side, the Portfolio benefited from its underweight in telecommunication
services. At the individual stock level, the largest positive contributors to
performance were The Ryland Group, Inc., CheckFree Corp., Countrywide Credit
Industries, Inc., AutoNation, Inc. and Aetna Inc. We also benefited from our
underweights in SBC Communications Inc. and Altria Group Inc. (formerly Philip
Morris Companies Inc.). The largest detractors to performance included
Hewlett-Packard Company, Adolph Coors Company and Sprint Corporation. Our
largest purchases included J.P. Morgan Chase & Co., Merck & Co., Inc., Sprint
and Hewlett-Packard, while our largest sales included Gannett Co., Inc.,
National City Corporation and The Procter & Gamble Company.

During the course of the period, we increased our positions relative to the
benchmark in technology, health care and energy, and reduced our holdings in
consumer staples, industrials and consumer discretionary. Our largest
overweights were in information technology and health care, while our largest
underweights were in industrials, materials, and utilities. We are positioned
for an improvement in economic activity, continued positive earnings
comparisons, and an eventual uptick in interest rates. As always, we seek to own
companies that we believe have improving earnings momentum, a high probability
of positive earnings surprises, and reasonable valuations.

Economic Environment

To provide a larger context in which to view the portfolio, it is important to
understand that the economy has suffered a sharp loss of confidence this year.
The Conference Board survey showed that employment conditions are at risk of
deteriorating. Although new unemployment claims have not surged, jobs are still
seen as hard to come by, indicating that new job creation is still weak. The
risk is that a new round of layoffs and investment cutbacks will occur if the
business sector sees final demand slipping. Consumption has slowed in the past
two months, partly owing to bad weather, but also because confidence was hit by
the deterioration in the geopolitical backdrop and energy price crunch. While
there has been a modest drop in oil and natural gas prices recently, the relief
is not sufficient to offset renewed concerns about employment.

Treasury securities remain overvalued, but are likely to remain so until
economic expectations stabilize and deflation fears ease. The Federal Reserve
Board is going to continue to focus on trying to boost the economy and will not
contemplate shifting from this stance until well after the economy has
strengthened. In our opinion, longer-term investors should stay underweight in
bonds (slightly below-average duration), and within bond portfolios maintain an
overweight stance on corporates. Corporate bonds have weathered a difficult
economic patch in recent months, underscoring the power of good value and
improving corporate balance sheets.

The Standard & Poor's 500 Index is roughly in the middle of its trading range
(800-950), and we remain hopeful that a test of the upper end will develop. A
break to the upside would likely occur if the economy and corporate earnings
improve in a sustainable fashion. While profits have managed to do a bit better
than expected, some of this has been driven by cutbacks in investment and labor,
which have been economically bearish. Continued strong productivity growth
helped to contain unit labor costs, while pricing power improved a bit. Profits
likely suffered a setback in the first quarter given the spike in energy costs
and softness in overall demand. The budding stability in pricing power will be
in jeopardy unless demand growth re-accelerates. The profit environment will
remain tough, but the corporate sector is still focused on boosting the bottom
line, raising the hope that better times loom once the drag from the war lifts
and oil prices correct further. Investors need to believe that corporate profits
will rise in a self-reinforcing fashion before they will shift funds into
equities, particularly given the lack of great value in the market. It could be
a few months before the economic data clarifies whether the economy is still on
a recovery track or has been delayed or derailed. Until then, equities are
likely to remain trendless. While other investments are not offering much
competition to stocks, investors also have lost considerable capital in the
equity market since March 2000, and will remain leery, absent clear evidence
that the world economy is healing.

The bottom line is that the economy has taken a hard blow this year, but it is
not yet down for the count. If the economy does not revive soon, then hopes for
another equity upleg are likely to be dashed. Worse, equities could break below
their October 2002 low if the economy falters. Investors are already deeply
pessimistic and monetary policy will stay highly reflationary, but these
conditions are not sufficient to spur a bull market in the absence of stronger
earnings. Importantly, investors and the business sector need greater confidence
and rising hopes for a more profitable future in order to take risks. The energy
market and geopolitical backdrop have punished risk-taking and only these
factors can help restore some vitality.

In Conclusion

We appreciate your investment in Merrill Lynch Large Cap Value Fund, and we look
forward to serving your financial needs in the months and years ahead.

Sincerely,

PERFORMANCE DATA

About Fund
Performance

Effective April 14, 2003, Class A Shares were redesignated Class I Shares and
Class D Shares were redesignated Class A Shares. Investors are able to purchase
shares of the Fund through multiple pricing alternatives:

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

o     Effective June 1, 2001, 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% and an account maintenance fee of 0.25%. These shares automatically
      convert to Class A Shares after approximately eight years. (There is no
      initial sales charge for automatic share conversions.)

o     Class C Shares are subject to a distribution fee of 0.75% and an account
      maintenance fee of 0.25%. 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% and an account maintenance fee of 0.25%. Class R Shares are
      available only to certain retirement plans.

None of the past results shown should be considered a representation of future
performance. 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 gains distributions 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.
The Fund's Administrator voluntarily waived a portion of its administration fee.
Without such waiver, and reimbursement of expenses, the Fund's performance would
have been lower.

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 a
diversified mutual fund. The Fund seeks to achieve its investment objective by
investing all of its assets in the Master Large Cap Value Portfolio (the
"Portfolio"), which is a portfolio of Master Large Cap Series Trust that has the
same investment objective 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 accounting principles generally
accepted in the United States of America, which may require the use of
management accruals and estimates. These unaudited financial statements reflect
all adjustments, which are, in the opinion of management, necessary to a fair
statement of the results for the interim period presented. All such adjustments
are of a normal, recurring nature. The percentage of the Portfolio owned by the
Fund at April 30, 2003 was 100%. The Fund offers multiple classes of shares.
Effective April 14, 2003, Class A Shares were redesignated Class I Shares and
Class D Shares were redesignated Class A Shares. The Fund's financial statements
and financial highlights, contained within this report, reflect the new share
class redesignation. Shares of Class I and Class A 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. Income, expenses (other than expenses attributable to
a specific class) and realized and unrealized gains and losses on investments
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 1a 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. 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"), a 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 Plans
with FAM Distributors, Inc. ("FAMD" or the "Distributor"), which is a
wholly-owned subsidiary of Merrill Lynch Group, 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 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 A ......................................      .25%                 --

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

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

For the six months ended April 30, 2003, 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 A .......................................... $4,458             $68,844
Class I .......................................... $   37             $   520
- --------------------------------------------------------------------------------

For the six months ended April 30, 2003, MLPF&S received contingent deferred
sales charges of $211,370 and $10,696 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, 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 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 accounting principles generally accepted in the
United States of America, which may require the use of management accruals and
estimates. These unaudited financial statements reflect all adjustments, which
are, in the opinion of management, necessary to a fair statement of the results
for the interim period presented. 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 -- Portfolio securities that are traded on stock
exchanges or Nasdaq National are valued at the last sale price or official
closing price on the exchange on which such securities are traded 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 ask price for short positions. Securities traded in the
over-the-counter market are valued at the last available bid price to the time
of valuation. Portfolio securities that are traded both in the over-the-counter
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. In the case of options traded in
the over-the-counter market, valuation is the last asked price (options written)
or the last bid price (options purchased). Short-term securities are valued at
amortized cost, which approximates market value. Other investments, including
futures contracts and related options, are stated at market value. Securities
and assets for which market quotations are not readily available are valued at
fair market value, as determined in good faith by or under the direction of the
Trust's Board of Trustees. Occasionally, events affecting the values of
securities and other assets may occur between the times at which valuations of
such securities are determined (that is, close of the market on which such
securities trade) and the close of business on the NYSE. If events (for example,
company announcement, natural disasters, market volatility) occur during such
periods that are expected to materially affect the value for such securities,
those securities may be valued at their fair market 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 Board of Trustees of the
Trust.

(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 movement 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 futures contracts. 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 is authorized to 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 is authorized to 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, the Portfolio typically receives the
income on both the loaned securities and the collateral and, as a result, the
Portfolio's yield may increase. 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. The Portfolio may receive a flat fee for
its loans. 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 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) Custodian bank -- The Fund 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 .75% of the average daily
value of the Portfolio's net assets. Effective January 17, 2001, the annual rate
was changed to .50%. 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 Fund. There is no increase in the aggregate fees paid by the Fund for these
services.

In addition, Merrill Lynch, Pierce, Fenner & Smith ("MLPF&S") received $60 in
commissions on the execution of portfolio security transactions for the Fund for
the six months ended April 30, 2003.

For the six months ended April 30, 2003, the Fund reimbursed FAM $4,440 for
certain accounting services.

The Portfolio has received an exemptive order from the Securities and Exchange
Commission permitting it to lend portfolio securities to MLPF&S Incorporated or
its affiliates. As of April 30, 2003, the Portfolio lent securities with a value
of $7,746,344 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 funds advised by FAM or its affiliates. For the six
months ended April 30, 2003, MLIM, LLC received $13,038 in securities lending
agent fees.

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, 2003 were $328,840,263 and $311,752,378, respectively.

As of April 30, 2003, net unrealized appreciation for Federal income tax
purposes aggregated $16,551,553, of which $31,739,578 related to appreciated
securities and $15,188,025 related to depreciated securities. At April 30, 2003,
the aggregate cost of investments for Federal income tax purposes was
$459,566,286.

4. Short-Term Borrowings:

The Fund, along with certain other funds managed by FAM and its affiliates, is a
party to a $500,000,000 credit agreement with Bank One, N.A. and certain other
lenders. 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 .09% per
annum based on the Fund's pro rata share of the unused portion of the credit
agreement. Amounts borrowed under the credit agreement bear interest at a rate
equal to, at each fund's election, the Federal Funds rate plus .50% or a base
rate as determined by Bank One, N.A. On November 29, 2002, the credit agreement
was renewed for one year under the same terms, except that the commitment was
reduced from $1,000,000,000 to $500,000,000. The Fund did not borrow under the
credit agreement during the six months ended April 30, 2003.
