A Letter From the President

Dear Shareholder

As 2003 draws to a close, it seems appropriate to reflect on what has been a
meaningful year in many respects. We saw the beginning and the end of all-out
war in Iraq, equity market uncertainty turned to strength and sub par gross
domestic product (GDP) growth of 1.4% in the first quarter of 2003 grew to an
extraordinary 8.2% in the third quarter.

Equity markets rebounded from one of the most dismal three-year periods in
history to make a strong showing this year. The S&P 500 Index posted
year-to-date and 12-month returns of +21.21% and +20.80%, respectively, as of
October 31, 2003. Although continued market strength cannot be assured, the
positives have begun to eclipse the negatives. In addition to the impressive GDP
growth, the positive economic news includes waning risk of deflation and
surprisingly strong business spending and corporate earnings. In fact, business
spending in the third quarter was the strongest it has been in three years, up
14%, and many company earnings reports exceeded forecasts in the first three
quarters of the year. The good news did not go unnoticed, as investors appeared
to regain confidence by returning to the equity market.

Against this backdrop, our portfolio managers continued to work diligently to
deliver on our commitment to provide superior performance within reasonable
expectations for risk and return. This included striving to outperform our peers
and the market indexes. With that said, remember that the advice and guidance of
a skilled financial advisor often can mean the difference between successful and
unsuccessful investing. A financial professional can help you choose those
investments that will best serve you as you plan for your financial future.

Finally, I am proud to premiere a new look to our shareholder communications.
Our portfolio manager commentaries have been trimmed and organized in such a way
that you can get the information you need at a glance, in plain language.
Today's markets are confusing enough. We want to help you put it all in
perspective. The report's new size also allows us certain mailing efficiencies.
Any cost savings in production or postage are passed on to the Fund and,
ultimately, to Fund shareholders.

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/ Terry K. Glenn

                                                Terry K. Glenn
                                                President and Director/Trustee

A Discussion With Your Fund's Portfolio Manager

      The Fund outperformed its benchmark for the period and remained positioned
to benefit from improving corporate earnings and economic revitalization, which
we believe will persist into 2004.

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

For the 12-month period ended October 31, 2003, the Fund's Class A, Class B,
Class C and Class I Shares had total returns of +23.47%, +22.56%, +22.40% and
+23.76%, respectively. (Fund results shown do not reflect sales charges, and
would be lower if sales charges were included. Complete performance information
can be found on pages 6 - 9 of this report to shareholders.) These results
compare quite favorably to the +21.81% total return of the Fund's unmanaged
benchmark, the Russell 1000 Growth Index, for the same period. In addition, the
Fund outperformed its comparable Lipper category of Large-Cap Growth Funds,
which posted an average return of +19.06% for the same 12-month period.

For the six months ended October 31, 2003, the Fund's Class A, Class B, Class C
and Class I Shares had total returns of +25.04%, +24.55%, +24.39% and +25.12%,
respectively. The six-month results were well ahead of the +16.81% total return
of the Russell 1000 Growth Index and the +15.53% average return of the Lipper
Large-Cap Growth Funds for the same period.

The Fund invests primarily in a diversified portfolio (Master Large Cap Growth
Portfolio) of large cap companies selected from securities found in the Russell
1000 Index. During this particular period, the main drivers of the positive
performance were stock selection in the consumer staples, consumer
discretionary, financials and energy sectors, and an overweight in consumer
discretionary. In contrast, stock selection in the information technology sector
had a negative impact on Fund returns.

In the last six months of the fiscal year, the Portfolio began to benefit from
its exposure to cyclical stocks -- those believed to strengthen along with a
strengthening economy. This enabled the Fund to gain significant ground relative
to both its benchmark and its peers. During the six-month period, the Fund
benefited from stock selection in consumer discretionary, health care and
information technology. Stock selection in financials, however, had a negative
impact on performance.

At the individual stock level, the largest positive contributors to performance
in the last six months were Invitrogen Corporation, Amkor Technology, Inc.,
National Semiconductor Corporation and SanDisk Corporation. Performance also
benefited from an underweight in Johnson & Johnson. The largest detractor from
performance was Sprint Corp. (PCS Group). Underweights in Intel Corporation and
Altria Group Inc. also had a negative impact on performance.

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. The last quarter of 2002 and the first quarter of 2003 were marked
by dramatic rises and falls in world markets, sub par economic growth and frail
consumer confidence. This was prompted by geopolitical uncertainties,
particularly war fears, and exacerbated by a weak employment picture. The period
following the Iraq war, however, saw a rise in investor confidence that drove
the major stock market indexes to levels not seen since early in 2002. Despite
alternating periods of rising and falling consumer confidence, spending by
consumers helped propel the slow and steady growth of the economy throughout the
entire period. Capital spending by businesses remained sluggish until late in
the period when signs of a pick-up began to emerge, along with improved
corporate earnings and a third-quarter 2003 jump in gross domestic product.


4       MERRILL LYNCH LARGE CAP GROWTH FUND           OCTOBER 31, 2003


What changes were made to the Portfolio during the fiscal year?

We increased our position relative to the benchmark in the information
technology sector, based on our belief that stocks in this sector would benefit
from the increases in business and consumer spending that accompany economic
recovery. We reduced our positions in consumer staples, health care and
industrials. Consumer staples tend to be more defensive in nature and we would
not expect the sector to benefit meaningfully during times of economic recovery.
Within health care, we reduced our positions in large-capitalization
pharmaceuticals. In our view, growth rates for stocks in this area are likely to
slow given increased competition, heightened government regulation and a
diminishing new-product pipeline. However, we were slightly overweight in health
care service providers and equipment suppliers because we see favorable
demographics and strong unit growth in this area. The largest purchases during
the period included Arrow Electronics, Inc., Blockbuster Inc., Intel
Corporation, D.R. Horton, Inc., Staples, Inc. and QUALCOMM Inc. The largest
sales included Dell Computer Corporation, Fannie Mae, Varian Medical Systems,
Inc., H&R Block, Inc. and CheckFree Corp.

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

The Portfolio's largest overweights as of October 31, 2003 were in information
technology and consumer discretionary, which we believe should continue to
benefit from economic improvement. The largest underweights were in consumer
staples and health care.

Companies exhibiting good earnings momentum, earnings surprise and valuation
characteristics saw a pick-up in performance late in the summer that accelerated
in the fall. We remain committed to these disciplines for stock selection,
although cognizant that the equity market could experience a temporary downturn
at any time.

Looking ahead, we believe the economic recovery will continue to gain traction.
Record monetary and fiscal policy stimulus, in the form of low interest rates
and tax cuts, along with solid consumer spending and increasing business
spending, all support this thesis. The job market was still disappointingly weak
as we ended the period, but there were signs of improvement.

As low interest rates continue to make for a positive liquidity environment, we
are reluctant to abandon our strategy of focusing on cyclical stocks that have
the potential to benefit from economic recovery. We are prepared to move to a
more cautious investment stance as the likelihood of monetary tightening by the
Federal Reserve Board approaches, although that still seems months away. From a
longer-term perspective, the U.S. current account imbalance and the potential
for a destabilizing decline in the dollar pose the greatest threats to our
outlook. We will continue to monitor these situations for developments that
could potentially impact the Fund.

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     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.

Notes to Financial Statements                Merrill Lynch Large Cap Growth Fund

1. Significant Accounting Policies:

Merrill Lynch Large Cap Growth 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 mutual fund. The Fund seeks to achieve its investment
objective by investing all of its assets in the Master Large Cap Growth
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. The percentage of the Portfolio
owned by the Fund at October 31, 2003 was 100.0%. 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 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. Income, expenses (other than
expenses attributable to a specific class) and realized and unrealized gains and
losses on investments (and foreign currency transactions) 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, a withholding tax may be imposed on interest, dividends and capital gains
at various rates.

(d) Prepaid registration fees -- Prepaid registration fees are charged to
expenses 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) Reclassification -- Accounting principles generally accepted in the United
States of America require that certain components of net assets be adjusted to
reflect permanent differences between financial and tax reporting. Accordingly,
the current year's permanent book/tax differences of $2,682,487 have been
reclassified between paid-in capital in excess of par and accumulated net
investment loss, $153,963 has been reclassified between paid-in capital in
excess of par and accumulated net realized capital losses and $19 has been
reclassified between paid-in capital in excess of par and unrealized
appreciation. These reclassifications have no effect on net assets or net asset
values per share.

4. Distributions to Shareholders:

As of October 31, 2003, the components of accumulated losses on a tax basis were
as follows:

- -----------------------------------------------------------------------------
Undistributed ordinary income--net .....................        $          --
Undistributed long-term capital gains--net .............                   --

Unrealized gains--net ..................................           35,585,622**
                                                                -------------

                                                                =============

*     On October 31, 2003, the Fund had a net capital loss carryforward of
      $106,177,155, of which $10,449,992 expires in 2007, $2,792,851 expires in
      2008, $52,484,238 expires in 2009 and $40,450,074 expires in 2010. This
      amount will be available to offset like amounts of any future taxable
      gains.
**    The difference between book-basis and tax-basis net unrealized gains is
      attributable primarily to the tax deferral of losses on wash sales.

5. Acquisition of Mercury Large Cap Growth Fund:

On April 28, 2003, the Fund acquired all of the net assets of Mercury Large Cap
Growth Fund pursuant to a plan of reorganization. The acquisition was
accomplished by a tax-free exchange of 175,250 shares of Common Stock of Mercury
Large Cap Growth Fund for 157,517 shares of Common Stock of the Fund. Mercury
Large Cap Growth Fund's net assets on that date of $951,522, including $40,979
of net unrealized appreciation and $507,766 of accumulated net realized capital
losses, were combined with those of the Fund. The aggregate net assets
immediately after the acquisition amounted to $186,894,450.

We have audited the accompanying statement of assets and liabilities of Merrill

operations for the year then ended, the statements of changes in net assets for
each of the two years in the period then ended, and the financial highlights for
each of the respective periods then ended. These financial statements and
financial highlights are the responsibility of the Fund's management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States of America. Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. An audit also includes assessing the
accounting principles used and significant estimates made by management, as well
as evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
Merrill Lynch Large Cap Growth Fund as of October 31, 2003, the results of its
operations for the year then ended, the changes in its net assets for each of

Notes to Financial Statements                  Master Large Cap Growth Portfolio

1. Significant Accounting Policies:

Master Large Cap Growth Portfolio (the "Portfolio") is part of Master Large Cap
Series Trust (the "Trust"). The Portfolio 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 accounting principles generally
accepted in the United States of America, which may require the use of
management accruals and estimates. 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 ask
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
Portfolio. 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 Portfolio. Short positions traded in the OTC market are
valued at the last available ask 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 Portfolio, 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
Portfolio's Board of Trustees. Such valuations and procedures will be reviewed
periodically by the Board of Trustees of the Portfolio.

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 asset value 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 asset value. If events (for example, a company announcement,
market volatility or a natural disaster) occur during such periods that are
expected to materially affect the value of such securities, those securities may
be valued at their fair value as determined in good faith by the Portfolio's
Board of Trustees or by the Investment Adviser using a pricing service and/or
procedures approved by the Portfolio'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 futures contracts. Futures
      contracts are contracts for


30      MERRILL LYNCH LARGE CAP GROWTH FUND           OCTOBER 31, 2003


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

      delayed delivery of securities at a specific future 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 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. 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 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 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.

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., Ltd. ("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 or its affiliates. As of October 31, 2003, the
Portfolio lent securities with a value of $2,402,840 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 year ended October 31, 2003,
MLIM, LLC received $8,851 in securities lending agent fees.

For the year ended October 31, 2003, the Portfolio reimbursed FAM $4,308 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
year ended October 31, 2003 were $375,858,384 and $359,349,821, respectively.

- --------------------------------------------------------------------------------
                                                  Realized            Unrealized
                                                   Gains                Gains
- --------------------------------------------------------------------------------
Long-term investments ................          $10,011,741          $40,131,657
                                                --------------------------------
Total ................................          $10,011,741          $40,131,657
                                                ================================

As of October 31, 2003, net unrealized appreciation for Federal income tax
purposes aggregated $35,585,137, of which $44,238,090 related to appreciated
securities and $8,652,953 related to depreciated securities. At October 31,
2003, the aggregate cost of investments for Federal income tax purposes was
$242,967,784.

4. Short-Term Borrowings:

The Portfolio, along with certain other funds managed by FAM and its affiliates,
is party to a $500,000,000 credit agreement with Bank One, N.A. and certain
other lenders. The Portfolio may borrow under the credit agreement to fund
investor withdrawals 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 .09% per annum based on the Portfolio's pro rata share of the unused
portion of the facility. Amounts borrowed under the facility 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 28, 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 Portfolio did
not borrow under the facility during the year ended October 31, 2003.

Independent Auditors' Report                   Master Large Cap Growth Portfolio

The Investors and Board of Trustees of
Master Large Cap Growth Portfolio
(One of the Series constituting Master Large
Cap Series Trust):

We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of Master Large Cap Growth Portfolio as of October
31, 2003, and the related statement of operations for the year then ended, the
statements of changes in net assets for each of the two years in the period then
ended, and the financial highlights for each of the respective periods then
ended. These financial statements and financial highlights are the
responsibility of the Portfolio's management. Our responsibility is to express
an opinion on these financial statements and financial highlights based on our
audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States of America. Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free from material misstatement. An
audit includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2003, by correspondence with the custodian
and brokers; where replies were not received from brokers, we performed other
auditing procedures. An audit also includes assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of Master
Large Cap Growth Portfolio as of October 31, 2003, the results of its operations
for the year then ended, the changes in its net assets for each of the two years
in the period then ended, and its financial highlights for the respective
periods then ended, in conformity with accounting principles generally accepted
in the United States of America.
