A Letter From the President

Dear Shareholder

As we ended the current reporting period, the financial markets were facing a
number of uncertainties. At the top of investors' minds were questions about
economic expansion, corporate earnings, interest rates and inflation, politics,
oil prices and terrorism.

After benefiting from aggressive monetary and fiscal policy stimulus, some fear
the U.S. economy has hit a "soft patch." In fact, economic expansion has slowed
somewhat in recent months, but we believe it is easing into a pace of growth
that is sustainable and healthy. The favorable economic environment has served
to benefit American corporations, which have continued to post strong earnings.
Although the most impressive results were seen earlier in the year, solid
productivity, improved revenue growth and cost discipline all point to a vital
corporate sector.

In terms of inflation and interest rates, the Federal Reserve Board (the Fed)
has signaled its confidence in the economic recovery by increasing the Federal
Funds target rate four times in the past several months, from 1% to 2% as of the
November 10 Federal Open Market Committee meeting. Inflation, for its part, has
remained in check. Investors and economists are focused on how quickly monetary
policy will move from here, anxiously absorbing every bit of economic data and
Fed innuendo.

With the presidential election now behind us, any politically provoked market
angst should subside to some extent. The effect of oil prices, however, is more
difficult to predict. At around $50 per barrel, the price of oil is clearly a
concern. However, on an inflation-adjusted basis and considering modern usage
levels, the situation is far from the crisis proportions we saw in the 1980s.
Finally, although terrorism and geopolitical tensions are realities we are
forced to live with today, history has shown us that the financial effects of
any single event tend to be short-lived.

Amid the uncertainty, the Standard & Poor's 500 Index returned +9.42% for the
12-month period and +2.96% for the six-month period ended October 31, 2004. As
always, our investment professionals are closely monitoring the markets, the
economy and the overall environment in an effort to make well-informed decisions
for the portfolios they manage. For the individual investor, the key during
uncertain times is to remain focused on the big picture. While tracking current
events is important, investment success comes not from reacting to short-term
volatility, but from maintaining a long-term perspective and adhering to the
disciplines of asset allocation, diversification and rebalancing. We encourage
you to work with your financial advisor to ensure these time-tested techniques
are incorporated into your investment plan. 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 provided positive returns for the year, outperforming the
benchmark Russell 1000 Growth Index and pacing its comparable Lipper category of
Multi-Cap Growth Funds.

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

For the 12-month period ended October 31, 2004, Merrill Lynch Large Cap Growth
Fund's Class A, Class B, Class C, Class I and Class R Shares had total returns
of +4.69%, +3.92%, +3.92%, +4.89% and +4.39%, 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.) Fund returns exceeded the +3.38% return of the benchmark Russell
1000 Growth Index and were generally competitive with the +4.67% average return
of its comparable Lipper category of Multi-Cap Growth Funds. (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 growth funds typically have an
above-average price-to-earnings ratio, price-to-book ratio and three-year
sales-per-growth value compared to the S&P SuperComposite 1500 Index.)

For the six-month period ended October 31, 2004, the Fund outperformed both its
benchmark and the Lipper category average. The Fund's Class A, Class B, Class C,
Class I and Class R Shares had total returns of +3.25%, +2.84%, +2.85%, +3.34%
and +3.06%, respectively, for the six months ended October 31, 2004. This
compared to a return of -.73% for the Russell 1000 Growth Index and +2.09% for
the Lipper Multi-Cap Growth Funds average.

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. Essentially, the past year could be described as two distinct
periods. The stock market performed strongly in the first six months, carrying
the momentum from year-end 2003 into the new year. Specifically, equities
gleaned support from favorable economic news, unprecedented fiscal and monetary
policy stimulus, extraordinary corporate earnings results, strong money flows
and attractive valuations. In the six months that followed, the market was much
more volatile, taking its cues from election-related uncertainty, violence in
Iraq, record-high oil prices, rising interest rates and a series of soft
economic data.

For the 12-month period, the value style of investing significantly outpaced
growth. The Standard & Poor's 500 (S&P 500) Barra Growth Index recorded a
one-year return of +4.49% as of October 31, 2004, while the S&P 500 Barra Value
Index returned +14.46% for the same period. Also during the year, we witnessed a
"flight to quality," whereby investor favor shifted from low-quality, low-price
and higher-risk securities early in 2004 to higher-quality, higher-cap and
lower-risk stocks as investors became more cautious. Looking ahead, we believe
good stock picking is going to be more a matter of evaluating underlying company
fundamentals, with no clear winners in terms of sector, style or market cap
size.

What were the primary factors that influenced Fund performance?

The Fund invests primarily in a diversified portfolio of large cap companies
selected from securities found in the Russell 1000 Growth Index. Over the past
12 months, positive performance came from stock selection in the consumer
discretionary, especially specialty retailers, and health care sectors. This was
partially offset by stock selection in information technology and industrials,
especially education-related stocks.

At the individual stock level, the largest positive contributors to performance
were Harman International Industries, Incorporated, American Eagle Outfitters,
Inc., Urban Outfitters, Inc., The Home Depot Inc., Limited Brands, Inc., Oxford
Health Plans, Inc. and Autodesk, Inc. The largest detractors from performance
included Best Buy Co., Inc., Blockbuster Inc., Rite Aid Corporation, ImClone
Systems, ITT Educational Services Inc., Amkor Technology, Inc. and Cypress
Semiconductor Corporation. In addition, our underweight position in UnitedHealth
Group Incorporated negatively affected performance.


4       MERRILL LYNCH LARGE CAP GROWTH FUND        OCTOBER 31, 2004


What changes were made to the Portfolio during the year?

We maintained a procyclical bias for the majority of the fiscal year, investing
in those companies and sectors that we believed could benefit from a burgeoning
U.S. economy. For the most part, portfolio activity involved fine-tuning our
exposures based on our fundamental research, including the use of both
qualitative and quantitative screens. Although we continue to believe the U.S.
economy is on relatively solid footing, we had moderated our cyclical focus to
some extent by period-end as investors grew somewhat more cautious.

From a sector perspective, we increased our positions relative to the Russell
1000 Growth Index in health care, industrials and energy. Conversely, we reduced
exposure relative to the benchmark in information technology, financials and
consumer discretionary, although we remained significantly overweight in this
sector at period-end.

In terms of individual stocks, we continued to search for companies with what we
viewed as good earnings momentum and compelling valuations. The largest
purchases during the year included Johnson & Johnson, Pfizer, Inc., The Home
Depot, Inc., Cree, Inc., Medtronic, Inc., The Gillette Company, The Boeing
Company and QUALCOMM Incorporated. Among the largest sales were General Electric
Company, Intel Corporation, Cendant Corporation, Station Casinos Inc., Yahoo!
Inc., Apollo Group Inc., Rite Aid Corporation and Sprint Corp. (PCS).

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

In general, we maintain our focus on cyclical stocks in anticipation of positive
economic developments and continued strong earnings growth. Some observers have
come to question the vitality of economic growth in recent months, citing
negligible inflation, slowing consumer spending and record-high oil prices.
However, we continue to believe that the foundations of the economy are
reasonably strong and corporate balance sheets are in good shape. Corporations
continue to post earnings increases well above the historical average of 7%. At
this time, the market has already found some relief in the conclusion of the
presidential election. Investors appear to have viewed the re-election of
President Bush as a positive for American businesses.

Based on our relatively optimistic view, the Portfolio's largest overweights
compared to the Russell 1000 Growth Index as of October 31, 2004 were in
consumer discretionary, materials and energy. In our view, these sectors should
benefit from continued strong corporate earnings growth. The Portfolio's largest
underweights compared to the Russell 1000 Growth Index at period-end were in
financials, which tend to underperform in periods of rising interest rates, and
consumer staples, traditionally a more defensive sector.

We remain committed to our search for companies exhibiting good earnings
momentum, earnings surprise and favorable valuation characteristics, and that we
believe are positioned to deliver strong performance over the long term.

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 May 1, 2004 and held through
October 31, 2004) is intended to assist shareholders both in calculating
expenses based on an investment in the Fund and in comparing these expenses with
similar costs of investing in other mutual funds.

The first table below provides information about actual account values and
actual expenses. In order to estimate the expenses a shareholder paid during the
period covered by this report, shareholders can divide their account value by
$1,000 and then multiply the result by the number in the first line under the
heading entitled "Expenses Paid During the Period."

The second table below provides information about hypothetical account values
and hypothetical expenses based on the Fund's actual expense ratio and an
assumed rate of return of 5% per year before expenses. In order to assist
shareholders in comparing the ongoing expenses of investing in this Fund and
other funds, compare the 5% hypothetical example with the 5% hypothetical
examples that appear in other funds' shareholder reports.

The expenses shown in the table are intended to highlight shareholders ongoing
costs only and do not reflect any transactional expenses, such as sales charges,
redemption fees, or exchange fees. Therefore, the second table is useful in
comparing ongoing expenses only, and will not help shareholders determine the
relative total expenses of owning different funds. If these transactional
expenses were included, shareholder expenses would have been higher.

*     For each class of the Fund, expenses are equal to the annualized expense
      ratio for the class (1.39% for Class A, 2.18% for Class B, 2.17% for Class
      C, 1.14% for Class I and 1.63% for Class R), multiplied by the average
      account value over the period, multiplied by 182/364 (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 364.

18      MERRILL LYNCH LARGE CAP GROWTH FUND        OCTOBER 31, 2004


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 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. The percentage of the Portfolio owned by the Fund at October 31, 2004
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 material changes to the Class A distribution plan).
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 -- U.S. generally accepted accounting principles require
that certain components of net assets be adjusted to reflect permanent
differences between financial and tax reporting. Accordingly, during the current
year, $3,345,613 has been reclassified between paid-in capital in excess of par
and accumulated net investment loss as a result of permanent differences
attributable to net operating losses and non-deductible expenses. This
reclassification has no effect on net assets or net asset values per share.

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 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

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, 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 year ended October 31, 2004, 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 ............................               $   111               $ 1,350

For the year ended October 31, 2004, MLPF&S received contingent deferred sales
charges of $166,821 and $11,403 relating to transactions in Class B and Class C
Shares of the Fund, respectively.

Financial Data Services, Inc. ("FDS"), a 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, PSI, FAMD, FDS, and/or ML & Co.

*     On October 31, 2004, the Fund had a net capital loss carryforward of
      $82,684,257, of which $7,837,494 expires in 2007, $2,749,271 expires in
      2008, $31,647,418 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.

28      MERRILL LYNCH LARGE CAP GROWTH FUND        OCTOBER 31, 2004


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 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. 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. 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. 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, 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 Trust under the general supervision of the Board of Trustees. Such
valuations and procedures will be reviewed periodically by the Board of
Trustees.

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
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 Board of Trustees or by the Investment Adviser
using a pricing service and/or procedures approved by the 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 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

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

      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. 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

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

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 Agree-ment 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, a subsidiary of ML & Co., 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, 2004, MLIM, LLC
received $10,029 in securities lending agent fees.

For the year ended October 31, 2004, the Portfolio reimbursed FAM $6,189 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, 2004 were $571,153,954 and $492,523,219, respectively.

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 a group of 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 defined in
the credit agreement. The Portfolio did not borrow under the facility during the
year ended October 31, 2004. On November 26, 2004, the credit agreement was
renewed for one year under substantially the same terms.

Report of Independent Registered Public Accounting Firm

                                               Master Large Cap Growth Portfolio

To the Investors and Board of Trustees of
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, one of the
series constituting Master Large Cap Series Trust (the "Trust"), as of October
31, 2004, 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 Trust'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 the standards of the Public Company
Accounting Oversight Board (United States). 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. Our procedures included confirmation of
securities owned as of October 31, 2004, 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 of Master Large Cap Series Trust as of October 31,
2004, 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 each of the respective periods then ended, in conformity with
U.S. generally accepted accounting principles.

         (e)(1) The registrant's audit committee (the "Committee") has adopted

         Audit, audit-related and tax compliance services provided to the

         Committee. The Committee also must approve other non-audit services

         registrant's affiliated service providers that relate directly to the
         operations and the financial reporting of the registrant. Certain of
         these non-audit services that the Committee believes are a) consistent
         with the SEC's auditor independence rules and b) routine and recurring
         services that will not impair the independence of the independent
         accountants may be approved by the Committee without consideration on a
         specific case-by-case basis ("general pre-approval"). However, such
         services will only be deemed pre-approved provided that any individual
         project does not exceed $5,000 attributable to the registrant or
         $50,000 for all of the registrants the Committee oversees. Any proposed
         services exceeding the pre-approved cost levels will require specific
         pre-approval by the Committee, as will any other services not subject
         to general pre-approval (e.g., unanticipated but permissible services).
         The Committee is informed of each service approved subject to general
         pre-approval at the next regularly scheduled in-person board meeting.
