Dear Shareholder

As the financial markets continued to muddle their way through 2005, the Federal
Reserve Board (the Fed) advanced its monetary tightening campaign full steam
ahead. The 12th consecutive interest rate hike since June 2004 came on November
1, bringing the target federal funds rate to 4%. The central bank is clearly
more focused on inflationary figures than on economic growth, which has shown
some signs of moderating. Despite rising short-term interest rates and
record-high energy prices, the major market indexes managed to post positive
results for the current reporting period:

The headlines in recent months focused on Hurricanes Katrina and Rita and, more
recently, the nomination of Ben Bernanke to succeed Alan Greenspan as Chairman
of the Fed. While the hurricanes prompted a spike in energy prices and
short-term disruptions to production and spending, the longer-term economic
impact is likely to be tempered. In fact, the fiscal stimulus associated with
reconstruction efforts in the Gulf Coast region could add to gross domestic
product growth in 2006. Notably, the uncontroversial nomination of Dr. Bernanke
was well received by the markets.

The U.S. equity markets remained largely range bound in 2005. Up to this point,
strong corporate earnings reports and relatively low long-term bond yields have
worked in favor of equities. Looking ahead, high energy prices, continued
interest rate hikes, a potential consumer slowdown and/or disappointing earnings
pose the greatest risks to U.S. stocks. Internationally, many markets have
benefited from strong economic statistics, trade surpluses and solid finances.

The bond market continued to be characterized by a flattening yield curve,
although long-term yields finally began to inch higher toward period end. The
10-year Treasury yield hit 4.57% on October 31, 2005, its highest level in more
than six months. Still, the difference between the two-year and 10-year Treasury
yield was just 17 basis points (.17%) at period end, compared to 149 basis
points a year earlier.

Financial markets are likely to face continued crosscurrents in the months
ahead. Nevertheless, opportunities do exist and we encourage you to work with
your financial advisor to diversify your portfolio among a variety of asset
types. This can help to diffuse risk while also tapping into the potential
benefits of a broader range of investment alternatives. As always, we thank you
for trusting Merrill Lynch Investment Managers with your investment assets.

                                Sincerely,


                                /s/ Robert C. Doll, Jr.

A Discussion With Your Funds' Portfolio Manager

      The Funds significantly outperformed their respective benchmarks for the
period, largely due to successful stock selection across various sectors and
good sector allocation decisions.

How did the Merrill Lynch Large Cap Series Funds perform during the fiscal year
in light of the existing market conditions?

For the 12-month period ended October 31, 2005, Merrill Lynch Large Cap Core
Fund's Class A, Class B, Class C, Class I and Class R Shares had total returns
of +17.61%, +16.69%, +16.80%, +17.94% and 17.39%, respectively, well ahead of
the +10.47% return of the benchmark Russell 1000 Index and the +10.50% average
return of its comparable Lipper category of Multi-Cap Core Funds*. Merrill Lynch
Large Cap Growth Fund's Class A, Class B, Class C, Class I and Class R Shares
had 12-month total returns of +11.62%, +10.80%, +10.82%, +11.96% and +11.39%,
respectively, exceeding the +8.81% return of the benchmark Russell 1000 Growth
Index. For the same period the Lipper Multi-Cap Growth Funds category had an
average return of +12.95%*. Merrill Lynch Large Cap Value Fund's Class A, Class
B, Class C, Class I and Class R Shares had total returns of +21.20%, +20.29%,
+20.31%, +21.49% and +20.93%, respectively, also surpassing the +11.86% return
of its benchmark, the Russell 1000 Value Index, and the +11.02% average return
of the Lipper Multi-Cap Value Funds category for the 12-month period*. (Fund
results shown do not reflect sales charges and would be lower if sales charges
were included. Complete performance information for each Fund can be found on
pages 6 - 10 of this report to shareholders.)

Because the Funds invest in large-capitalization stocks that represent a
significant part of the U.S. stock market, their portfolios were influenced by
the same economic and market events that affected the broader stock market
during the past 12 months. Impressive gains in the fourth quarter of 2004 were
given back in the early months of 2005 as major equity indexes struggled to find
their footing. The rally that followed the conclusion of the presidential
election in November 2004 was hampered by concerns over inflation, a weak U.S.
dollar and continuing interest rate hikes by the Federal Reserve Board (the
Fed). As of November 1, 2005, the Fed had increased the federal funds rate 12
consecutive times since June 2004, bringing the short-term interest rate target
to 4%. Oil prices continued to fluctuate and achieved record highs on more than
one occasion during the reporting period, leading to inflationary concerns, but
also contributing to strong performance from the energy sector.

January, March and April were particularly weak months for the market. May
through July brought a stock market upturn, as a significant number of
acquisition announcements, along with a resilient economy, solid consumer
spending, a robust housing sector, and solid growth in corporate profits, served
to boost equities. The summer rally was short-lived, however, as the markets
reacted to the uncertainty created in the aftermath of Hurricanes Katrina and
Rita. Specifically, equities stalled in response to spiking energy prices, still
rising interest rates, waning consumer confidence, the potential for slowing
corporate profit growth and impending new leadership at the Fed as Chairman Alan
Greenspan approaches the end of his 18-year tenure. Notably, the October 24
nomination of Dr. Ben Bernanke as Greenspan's replacement was well received by
the markets. Still, October ended as one of the weaker months of the fiscal
year.

What factors most influenced the Funds' performance during the fiscal year?

In the case of all three Funds, stock selection contributed positively to
returns in most sectors, including health care (particularly health care
providers and services) and financials (particularly insurance). In the energy
sector, the combination of a sector overweight and effective stock selection
enhanced returns, particularly in oil, gas and consumable fuels. Although stock
selection in the technology sector added to returns for Merrill Lynch Large Cap
Growth Fund, the combination of a sector overweight and stock selection
detracted from the relative performance of Merrill Lynch Large Cap Value Fund
and Merrill Lynch Large Cap Core Fund. Our positions in the consumer staples
sector detracted from relative performance in all three portfolios; however,
this was more than offset by the strong positive returns from other sectors.

*     Lipper Multi-Cap funds 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 Core funds
      typically have an average price-to-earnings ratio, price-to-book ratio and
      three-year sales-per-share growth value compared to the S&P SuperComposite
      1500 Index. 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.
      Multi-Cap Value funds typically have a below-average price-to-earnings
      ratio, price-to-book ratio and three-year sales-per-growth value compared
      to the S&P SuperComposite 1500 Index.


4       MERRILL LYNCH LARGE CAP SERIES FUNDS, INC.      OCTOBER 31, 2005


At the individual stock level (based on the combined effect of stock returns and
relative weightings in each Portfolio), the largest positive contributors to
Merrill Lynch Large Cap Core Fund's relative performance during the 12-month
period were Valero Energy Corp., Humana, Inc., PacifiCare Health Systems,
Sunoco, Inc., Express Scripts, Inc., Cigna Corp. and Autodesk, Inc. The largest
performance detractors included Altria Group, Inc., TIBCO Software, Inc.,
Symantec Corporation, Dell, Inc. and QLogic Corp. In the Merrill Lynch Large Cap
Growth Fund portfolio, the largest positive contributors to relative performance
were PacifiCare Health Systems, Aetna, Inc., Express Scripts, AutoDesk and
Burlington Resources, Inc. Stocks that detracted most from that Fund's relative
performance included Dell, Pfizer, Inc., Amgen, Inc., Advanced Micro Devices,
Inc. and Cree, Inc. In terms of Merrill Lynch Large Cap Value Fund, the largest
positive contributors to relative performance were Valero Energy, Humana,
PacifiCare Health Systems, Sunoco and Pfizer. The largest detractors included
Altria Group, Claire's Stores, Inc., Exxon Mobil Corp., QLogic and Energizer
Holdings, Inc. Our underweight position in Fannie Mae also had a positive impact
on the performance of all three Funds, as this was a negative contributor in all
three benchmarks.

What changes were made to the Portfolios during the fiscal period?

Overall, we continued to identify companies with favorable growth
characteristics and earnings developments, selling at attractive relative
valuations. As a result of our bottom-up stock-selection process, we increased
the Portfolios' positions in technology and energy while reducing exposure to
the consumer discretionary, materials and consumer staples sectors.

In Master Large Cap Core Portfolio, the largest purchases during the period
included Intel Corp., Dell, Exxon Mobil, Hewlett-Packard Co. and Texas
Instruments, Inc. The largest sales included Johnson & Johnson, Apple Computer,
Inc., Chevron Corp., PacifiCare Health Systems and Monsanto Co. In Master Large
Cap Growth Portfolio, the largest purchases included Intel Corp., Dell, Amgen,
General Electric Co. and Best Buy Co., Inc. The largest sales included Johnson &
Johnson, Pfizer, Microchip Technology, The Home Depot, Inc. and PacifiCare
Health Systems. In Master Large Cap Value Portfolio, the largest purchases
included Intel, Exxon Mobil, Goldman Sachs Group, Inc., Hewlett-Packard, The St.
Paul Travelers Companies, Inc. and MeadWestvaco Corp. The largest sales included
Chevron Texaco, The Bear Stearns Cos., Inc., PacifiCare Health Systems, Monsanto
and Chubb Corp.

These transactions reflect our ongoing refinement of the portfolios, as we
continue to look for stocks that best meet our investment criteria while pruning
those that have deteriorated versus our original assessment.

How would you characterize the Portfolios' positioning at the close of the
period?

The Portfolios' largest overweights as of October 31, 2005, were in the
technology and energy sectors. The largest underweights were in financials,
which tend to underperform in periods of rising interest rates, consumer
staples, utilities, industrials and telecommunications services.

Our view is that a somewhat conservative investment position makes sense, at
least until there is more evidence that the Fed is prepared to cease increasing
short-term interest rates. Recently reported third quarter gross domestic
product (GDP) data showed that, contrary to investors' concerns, core inflation
(which excludes food and energy prices) actually declined from the second
quarter. By early 2006, we believe it will become more evident that consumers
are retrenching, and that real GDP has decelerated to a more non-inflationary
pace, specifically 3% or less. Having said that, we continue to believe that a
highly diversified portfolio and a focus on individual security selection
(rather than a more macro approach) is appropriate and should be rewarded on a
relative basis.

About Fund Performance

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

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

o     Class B Shares are subject to a maximum contingent deferred sales charge
      of 4% declining to 0% after six years. In addition, Class B Shares are
      subject to a distribution fee of 0.75% per year and an account maintenance
      fee of 0.25% per year. These shares automatically convert to Class A
      Shares after approximately eight years. (There is no initial sales charge
      for automatic share conversions.) All returns for periods greater than
      eight years reflect this conversion.

o     Class C Shares are subject to a distribution fee of 0.75% per year and an
      account maintenance fee of 0.25% per year. In addition, Class C Shares are
      subject to a 1% contingent deferred sales charge if redeemed within one
      year of purchase.

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

o     Class R Shares do not incur a maximum sales charge (front-end load) or
      deferred sales charge. These shares are subject to a distribution fee of
      0.25% per year and an account maintenance fee of 0.25% per year. Class R
      Shares are available only to certain retirement plans. Prior to inception,
      Class R Share performance results are those of Class I Shares (which have
      no distribution or account maintenance fees) restated for Class R Share
      fees.

None of the past results shown should be considered a representation of future
performance. Current performance may be lower or higher than the performance
data quoted. Refer to www.mlim.ml.com to obtain performance data current to the
most recent month-end. Performance results do not reflect the deduction of taxes
that a shareholder would pay on fund distributions or the redemption of fund
shares. Figures shown in each of the following tables assume reinvestment of all
dividends and capital gain distributions, if any, at net asset value on the
ex-dividend date. Investment return and principal value of shares will fluctuate
so that shares, when redeemed, may be worth more or less than their original
cost. Dividends paid to each class of shares will vary because of the different
levels of account maintenance, distribution and transfer agency fees applicable
to each class, which are deducted from the income available to be paid to
shareholders.

Disclosure of Expenses

Shareholders of these Funds 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, 2005 and held
through October 31, 2005) is intended to assist shareholders both in calculating
expenses based on an investment in each 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 each 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 these Funds 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 (1.24% for Class A, 2.00% for Class B, 2.00% for Class
      C, .99% for Class I and 1.49% for Class R), multiplied by the average
      account value over the period, multiplied by 185/365 (to reflect the
      one-half year period shown). Because the Fund is a feeder fund, the
      expense table example reflects the expenses of both the feeder fund and
      the master portfolio in which it invests.
**    Hypothetical 5% annual return before expenses is calculated by pro-rating
      the number of days in the most recent fiscal half-year divided by 365.

Notes to Financial Statements   Merrill Lynch Large Cap Series Funds, Inc.

1. Significant Accounting Policies:

Merrill Lynch Large Cap Core Fund, Merrill Lynch Large Cap Growth Fund and
Merrill Lynch Large Cap Value Fund constituting Merrill Lynch Large Cap Series
Funds, Inc. (the "Funds" or individually as the "Fund") are registered under the
Investment Company Act of 1940, as amended, as diversified, open-end investment
companies. The Funds seek to achieve their investment objective by investing all
of their assets in the Master Large Cap Core Portfolio, Master Large Cap Growth
Portfolio and Master Large Cap Value Portfolio (the "Portfolios" or individually
as the "Portfolio"), respectively, constituting Master Large Cap Series Trust,
which have the same investment objective and strategies as the corresponding
Funds. The value of the Funds' investment in the Portfolios reflect the Funds'
proportionate interest in the net assets of the Portfolios. The performance of
the Funds is directly affected by the performance of the Portfolios. The
financial statements of the Portfolios, including the Schedules of Investments,
are included elsewhere in this report and should be read in conjunction with the
Funds' financial statements. The Funds' 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. On October 31, 2005, the percentage of Master Large Cap Core
Portfolio owned by Merrill Lynch Large Cap Core Fund was 92.4%, and the
percentage of Master Large Cap Growth Portfolio and Master Large Cap Value
Portfolio owned by Merrill Lynch Large Cap Growth Fund and Merrill Lynch Large
Cap Value Fund, respectively, was 100%. The Funds offer multiple classes of
shares. Shares of Class A and Class I are sold with a front-end sales charge.
Shares of Class B and Class C may be subject to a contingent deferred sales
charge. Class R Shares are sold only to certain retirement plans. All classes of
shares have identical voting, dividend, liquidation and other rights and the
same terms and conditions, except that Class A, Class B, Class C and Class R
Shares bear certain expenses related to the account maintenance of such shares,
and Class B, Class C and Class R Shares also bear certain expenses related to
the distribution of such shares. Each class has exclusive voting rights with
respect to matters relating to its account maintenance and distribution
expenditures (except that Class B shareholders may vote on certain changes to
Class A distribution plan). Income, expenses (other than expenses attributable
to a specific class) and realized and unrealized gains and losses are allocated
daily to each class based on its relative net assets. The following is a summary
of significant accounting policies followed by the Funds.

(a) Valuation of investments -- Each Fund records its investment in the
Portfolio at fair value. Valuation of securities held by the Portfolio is
discussed in Note 1(a) of the Portfolios' Notes to Financial Statements, which
are included elsewhere in this report.

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

(c) Income taxes -- It is each 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 each Fund
are recorded on the ex-dividend dates.

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

(g) Reclassifications --

Merrill Lynch Large Cap Core Fund

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, $5,488,189 has been
reclassified between undistributed net realized capital gains and accumulated
net investment loss, and $492,254 has been reclassified between paid-in capital
in excess of par and undistributed net realized capital gains as a result of
permanent differences attributable to net operating losses and other permanent
differences. These reclassifications have no effect on net assets or net asset
values per share.

Merrill Lynch Large Cap Growth Fund

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, $3,266,027 has been
reclassified between paid-in capital in excess of par and accumulated net
investment loss as a result of a permanent difference attributable to net
operating losses. This reclassification has no effect on net assets or net asset
values per share.

                                      Merrill Lynch Large Cap Series Funds, Inc.

Merrill Lynch Large Cap Value Fund

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, $2,354,785 has been
reclassified between undistributed net realized capital gains and accumulated
net investment loss as a result of a permanent difference attributable to net
operating loss. This reclassification has no effect on net assets or net asset
values per share.

2. Transactions with Affiliates:

Each 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. Each 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.

Each 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 Funds 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:

- --------------------------------------------------------------------------------

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

Pursuant to a sub-agreement with the Distributor, Merrill Lynch, Pierce, Fenner
& Smith Incorporated ("MLPF&S"), an affiliate of FAM, also provides account
maintenance and distribution services to the Funds. 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.

      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 and a
      limitation on the utilization of capital loss carryforwards for tax
      purposes.

                                      Merrill Lynch Large Cap Series Funds, Inc.

To the Shareholders and Board of Directors of
Merrill Lynch Large Cap Series Funds, Inc.:

We have audited the accompanying statements of assets and liabilities of Merrill
Lynch Large Cap Series Funds, Inc. (the "Fund"), comprising Merrill Lynch Large
Cap Core Fund, Merrill Lynch Large Cap Growth Fund and Merrill Lynch Large Cap
Value Fund, as of October 31, 2005, and the related statements 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
five years in the period 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 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. The Fund
is not required to have, nor were we engaged to perform, an audit of its
internal control over financial reporting. Our audits included consideration of
internal control over financial reporting as a basis for designing audit
procedures that are appropriate in the circumstances, but not for the purpose of
expressing an opinion on the effectiveness of the Fund's internal control over
financial reporting. Accordingly, we express no such opinion. An audit also
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, 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 each
of the funds constituting Merrill Lynch Large Cap Series Funds, Inc. as of
October 31, 2005, the results of their operations for the year then ended, the
changes in their net assets for each of the two years in the period then ended,
and their financial highlights for each of the five years in the period then
ended, in conformity with U.S. generally accepted accounting principles.

Notes to Financial Statements                      Master Large Cap Series Trust

1. Significant Accounting Policies:

Master Large Cap Core Portfolio, Master Large Cap Growth Portfolio and Master
Large Cap Value Portfolio (the "Portfolios" or individually as the "Portfolio")
constitute the 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 Portfolios' 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 each
Portfolio that are traded on stock exchanges or the Nasdaq National Market are
valued at the last sale price or official close price on the exchange, as of the
close of business on the day the securities are being valued or, lacking any
sales, at the last available bid price for long positions, and at the last
available asked price for short positions. In cases where equity securities are
traded on more than one exchange, the securities are valued on the exchange
designated as the primary market by or under the authority of the Board of
Trustees of the Trust. Long positions traded in the over-the-counter ("OTC")
market, Nasdaq Small Cap or Bulletin Board are valued at the last available bid
price or yield equivalent obtained from one or more dealers or pricing services
approved by the Board of Trustees of the Trust. Short positions traded in the
OTC market are valued at the last available asked price. Portfolio securities
that are traded both in the OTC market and on a stock exchange are valued
according to the broadest and most representative market.

Options written are valued at the last sale price in the case of exchange-traded
options or, in the case of options traded in the OTC market, the last ask price.
Options purchased are valued at their last sale price in the case of
exchange-traded options or, in the case of options traded in the OTC market, the
last bid price. Swap agreements are valued based upon quoted fair valuations
received daily by the Portfolios from a pricing service or counterparty.
Financial futures contracts and options thereon, which are traded on exchanges,
are valued at their last sale price as of the close of such exchanges.
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. Each Portfolio
employs pricing services to provide certain securities prices for the Portfolio.
Securities and assets for which market quotations are not readily available are
valued at fair value as determined in good faith by or under the direction of
the Board of Trustees of the Trust, including valuations furnished by the
pricing services retained by each 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 Trust's Board
of Trustees. Such valuations and procedures will be reviewed periodically by the
Board of Trustees of the Trust.

Generally, trading in foreign securities, as well as U.S. government securities,
money market instruments, and certain fixed income securities, is substantially
completed each day at various times prior to the close of business on the New
York Stock Exchange ("NYSE"). The values of such securities used in computing
the net assets of each 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 each Portfolio's net assets. If events (for example, a
company announcement, market volatility or a natural disaster) occur during such
periods that are expected to materially affect the value of such securities,
those securities may be valued at their fair value as determined in good faith
by the Trust's Board of Trustees or by the Investment Adviser using a pricing
service and/or procedures approved by the Trust's Board of Trustees.

(b) Derivative financial instruments -- Each 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 -- Each Portfolio may purchase or sell
      financial futures contracts and options on such futures contracts. Futures
      contracts are contracts for delayed delivery of securities at a specific
      date and at a specific price or yield. Upon entering into a contract, the
      Portfolio deposits and maintains as collateral such initial margin as
      required by the exchange on which the transaction is effected. Pursuant to
      the contract, the Portfolio


50      MERRILL LYNCH LARGE CAP SERIES FUNDS, INC.      OCTOBER 31, 2005


Notes to Financial Statements (continued)          Master Large Cap Series Trust

      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 -- Each 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.

(c) Income taxes -- Each 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.

(d) 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.

(e) Securities lending -- Each Portfolio may lend securities to financial
institutions that provide cash or securities issued or guaranteed by the U.S.
government as collateral, which will be maintained at all times in an amount
equal to at least 100% of the current market value of the loaned securities. The
market value of the loaned securities is determined at the close of business of
the Portfolio and any additional required collateral is delivered to the
Portfolio on the next business day. Where the Portfolio receives securities as
collateral for the loaned securities, it receives a fee from the borrower. The
Portfolio typically receives the income on the loaned securities, but does not
receive the income on the collateral. Where the Portfolio receives cash
collateral, it may invest such collateral and retain the amount earned on such
investment, net of any amount rebated to the borrower. Loans of securities are
terminable at any time and the borrower, after notice, is required to return
borrowed securities within five business days. The Portfolio may pay reasonable
finders, lending agent, administrative and custodial fees in connection with its
loans. In the event that the borrower defaults on its obligation to return
borrowed securities because of insolvency or for any other reason, the Portfolio
could experience delays and costs in gaining access to the collateral. The
Portfolio also could suffer a loss where the value of the collateral falls below
the market value of the borrowed securities, in the event of borrower default or
in the event of losses on investments made with cash collateral.

(f) Custodian bank --

Master Large Cap Core Portfolio

The Portfolio recorded an amount payable to the custodian bank reflecting an
overnight overdraft, which resulted from a failed trade that settled the next
day.

Master Large Cap Value Portfolio

The Portfolio recorded an amount payable to the custodian bank resulting from a
timing difference of security transaction settlements.

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 each 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
Master Large Cap Core Portfolio pays a monthly fee at an annual rate of .50% of
the average daily value of the Portfolio's net assets not


        MERRILL LYNCH LARGE CAP SERIES FUNDS, INC.      OCTOBER 31, 2005      51


Notes to Financial Statements (concluded)          Master Large Cap Series Trust

exceeding $1 billion and .45% of average daily net assets in excess of $1
billion. Master Large Cap Growth Portfolio and Master Large Cap Value Portfolio
each pay 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.

Each Portfolio has received an exemptive order from the Securities and Exchange
Commission permitting it to lend portfolio securities to Merrill Lynch, Pierce,
Fenner & Smith Incorporated ("MLPF&S"), an affiliate of FAM, or its affiliates.
As of October 31, 2005, the Master Large Cap Core Portfolio, Master Large Cap
Growth Portfolio and Master Large Cap Value Portfolio lent securities with
values of $11,244,452, $5,680,227 and $11,554,200, respectively, to MLPF&S or
its affiliates. Pursuant to that order, the Portfolios also have 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 Portfolios,
invest cash collateral received by the Portfolios for such loans, among other
things, in a private investment company managed by MLIM, LLC or in registered
money market Portfolios advised by FAM or its affiliates. For the year ended
October 31, 2005, MLIM, LLC received $77,387, $15,406 and $18,950 in securities
lending agent fees for Master Large Cap Core Portfolio, Master Large Cap Growth
Portfolio and Master Large Cap Value Portfolio, respectively.

For the year ended October 31, 2005, the Portfolios reimbursed FAM for certain
accounting services as follows:

                                                                   Reimbursement

- --------------------------------------------------------------------------------

4. Short-Term Borrowings:

Each 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,
which expires November 2005 and was subsequently renewed for one year under
substantially the same terms. The Portfolio may borrow under the credit
agreement to fund shareholder redemptions and for other lawful purposes other
than for leverage. The Portfolio may borrow up to the maximum amount allowable
under the Portfolio's current prospectus and statement of additional
information, subject to various other legal, regulatory or contractual limits.
The Portfolio pays a commitment fee of .07% per annum based on the Portfolio's
pro rata share of the unused portion of the credit agreement. Amounts borrowed
under the credit agreement bear interest at a rate equal to, at each Portfolio's
election, the federal funds rate plus .50% or a base rate as defined in the
credit agreement. None of the Portfolios borrowed under the credit agreement
during the year ended October 31, 2005.

                                                   Master Large Cap Series Trust

To the Investors and Board of Trustees of
Master Large Cap Series Trust:

We have audited the accompanying statements of assets and liabilities, including
the schedules of investments of Master Large Cap Series Trust (the "Trust"),
comprising Master Large Cap Core Portfolio, Master Large Cap Growth Portfolio
and Master Large Cap Value Portfolio, as of October 31, 2005, the related
statements 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 five years in the period 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. The Trust
is not required to have, nor were we engaged to perform, an audit of its
internal control over financial reporting. Our audits included consideration of
internal control over financial reporting as a basis for designing audit
procedures that are appropriate in the circumstances, but not for the purpose of
expressing an opinion on the effectiveness of the Trust's internal control over
financial reporting. Accordingly, we express no such opinion. An audit also
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. Our procedures included confirmation
of securities owned as of October 31, 2005, by correspondence with the custodian
and brokers; where replies were not received from brokers, we performed other
auditing procedures. 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 each
of the portfolios constituting Master Large Cap Series Trust, as of October 31,
2005, the results of their operations for the year then ended, the changes in
their net assets for each of the two years in the period then ended, and their
financial highlights for each of the five years in the period then ended, in
conformity with U.S. generally accepted accounting principles.

Disclosure of Investment Advisory Agreement

Activities of and Composition of the Board of Directors.

All but one member of each Fund's Board of Directors is an independent director
whose only association with the Investment Adviser or other Merrill Lynch
affiliates is as a director of the Funds and certain other funds advised by the
Investment Adviser or its affiliates. The Co-chairmen of the Board are also
independent directors. New director nominees are chosen as nominees by a
Nominating Committee comprised of independent directors. All independent
directors also are members of each Board's Audit Committee and the independent
directors meet in executive session at each regular Board meeting. Each Board
and the Audit Committee meet in person for at least two days each quarter and
conduct other in-person and telephone meetings throughout the year, some of
which are formal board meetings and some of which are informational meetings.
The independent counsel to the independent directors attends all in-person Board
and Audit Committee meetings and other meetings at the independent directors'
request.

Investment Advisory Agreements -- Matters Considered by the Board

Every year, the Board considers approval of the Investment Advisory Agreements
with respect to each Fund and throughout each year, reviews and evaluates the
performance of and services provided by the Investment Adviser. Each Board
assesses the nature, scope and quality of the services provided to the Trust
and/or the Fund by the personnel of the Investment Adviser, and its affiliates,
including administrative services, shareholder services, oversight of fund
accounting, marketing services and assistance in meeting legal and regulatory
requirements. Each Board also receives and assesses information regarding the
services provided to the Trust and the Fund by certain unaffiliated service
providers.

At various times throughout the year, each Board also considers a range of
information in connection with its oversight of the services provided by the
Investment Adviser and its affiliates. Among the matters considered with respect
to each Fund are: (a) fees (in addition to management fees) paid to the
Investment Adviser and its affiliates by the Trust and/or the Fund, such as
transfer agency fees and fees for marketing and distribution; (b) Trust or Fund
operating expenses paid to third parties; (c) the resources devoted to and
compliance reports relating to the Trust's and the Fund's investment objective,
policies and restrictions, and its compliance with its Code of Ethics and the
Investment Adviser's compliance policies and procedures; and (d) the nature,
cost and character of non-investment management services provided by the
Investment Adviser and its affiliates.

Each Board believes that the Investment Adviser is one of the most experienced
global asset management firms and considers the overall quality of services
provided by the Investment Adviser to be generally of high quality. Each Board
also believes that the Investment Adviser is financially sound and well managed
and notes that the Investment Adviser is affiliated with one of America's
largest financial firms. Each Board works closely with the Investment Adviser in
overseeing the Investment Adviser's efforts to achieve good performance. As part
of this effort, each Board discusses portfolio manager effectiveness and, when
performance is not satisfactory, discusses with the Investment Adviser taking
steps such as changing investment personnel.

Annual Consideration of Approval by the Board of Directors.

In the period prior to the Board meeting to consider renewal of the Investment
Advisory Agreements, each Board requests and receives materials specifically
relating to the Investment Advisory Agreements. These materials are prepared
separately with respect to each Fund, and include (a) information compiled by
Lipper Inc. ("Lipper") on the fees and expenses and the investment performance
of the Fund as compared to a comparable group of funds as classified by Lipper;
(b) sales and redemption data for the Fund; (c) a discussion by the
Trust's/Fund's portfolio management team regarding investment strategies used by
the Trust/Fund during its most recent fiscal year; (d) information on the
profitability to the Investment Adviser and its affiliates of the Investment
Advisory Agreements and other relationships with the Trust/Fund; and (e)
information provided by the Investment Adviser concerning investment advisory
fees charged to other clients, such as other mutual funds and offshore funds
under similar investment mandates and generally to institutional clients. The
Board also considers other matters it deems important to the approval process
such as payments made to the Investment Adviser or its affiliates relating to
the distribution of Fund shares, services related to the valuation and pricing
of Trust/Fund portfolio holdings, allocation of Trust/Fund brokerage fees, the
Trust's/Fund's portfolio turnover statistics, and direct and indirect benefits
to the Investment Adviser and its affiliates from their relationship with the
Trust/Fund.

Certain Specific Renewal Data

In connection with the most recent renewal of the Trust's Investment Advisory
Agreements, which occurred in May


54      MERRILL LYNCH LARGE CAP SERIES FUNDS, INC.      OCTOBER 31, 2005


2005, the independent Directors' and Board's review included the following:

The Investment Adviser's Services and Fund Performance -- Each Board reviewed
the nature, extent and quality of services provided by the Investment Adviser,
including the investment advisory services and the resulting performance of the
Fund. Each Board focused primarily on the Investment Adviser's investment
advisory services and the Fund's investment performance. Each Board compared the
Fund's performance -- both including and excluding the effects of the
Trust's/Fund's fees and expenses -- to the performance of a comparable group of
mutual funds, and the performance of a relevant index or combination of indexes.
While each Board reviews performance data at least quarterly, consistent with
the Investment Adviser's investment goals, the Board attaches more importance to
performance over relatively long periods of time, typically three to five years.
The Board noted that the Large Cap Growth Fund's performance within the group
compared for each of the one, three, and five year periods ended March 31, 2005
was in the second quartile. The Board noted that the Large Cap Core Fund's
performance within the group compared for each of the one and three year periods
ended March 31, 2005 was in the first quartile and in the second quartile for
the five year period ended March 31, 2005. The Board noted that the Large Cap
Value Fund's performance within the group compared for each of the one-, three-
and five-year periods ended March 31, 2005 was in the first quartile.
Considering these factors, each Board concluded that the nature and quality of
the services provided supported continuation of the Investment Advisory
Agreements.

The Investment Adviser's Personnel and Investment Process -- Each Board reviewed
the investment objectives and strategies of the Trust and the Fund. Each Board
discussed with senior management of the Investment Adviser responsible for
investment operations and the senior management of the Investment Adviser's
equity investing group the strategies being used to achieve the stated
objectives. Among other things, each Board considered the size, education and
experience of the Investment Adviser's investment staff, its use of technology,
and the Investment Adviser's approach to training and retaining portfolio
managers and other research, advisory and management personnel. Each Board also
reviewed the Investment Adviser's compensation policies and practices with
respect to the Trust's/Fund's portfolio manager. Each Board considered the
experience of the Trust's/Fund's portfolio manager and noted that Mr. Doll has
over twenty years experience in portfolio management. The Board concluded that
the Investment Adviser and its investment staff and the Trust's/Fund's portfolio
managers have extensive experience in analyzing and managing the types of
investments used by the Trust and the Fund and that the Trust and the Fund
benefit from that expertise.

Management Fees and Other Expenses -- Each Board reviewed the Trust's/Fund's
contractual management fee rate and actual management fee rate as a percentage
of total assets at common asset levels -- the actual rate includes advisory and
administrative service fees and the effects of any fee waivers -- compared to
the other funds in its Lipper category. It also compared the Trust's/Fund's
total expenses to those of other comparable funds. Each Board considered the
services provided to and the fees charged by the Investment Adviser to other
types of clients such as other mutual funds and off-shore funds, with similar
investment mandates and noted that the fees charged by the Investment Adviser in
those cases typically exceeded those being charged to the Trust/Fund. Each Board
also noted that, as a general matter, fees charged to institutional clients were
lower than the fees charged to the Trust/Fund, but determined that the
Investment Adviser provided less extensive services to such clients. The Board
noted that the Large Cap Growth Fund's contractual management fee rates for the
Fund was equal to the median fee rate charged by its peer group, as determined
by Lipper, while the Fund's actual management fee rate and total expenses were
below the median fees and expenses charged by its peers. The Board noted that
the Large Cap Core Fund's contractual and actual management fee rates for the
Fund, as well as its total expenses, were above the median fee rates charged by
its peer group as determined by Lipper. The Board noted that the Large Cap Value
Fund's contractual and actual management fee rates for the Fund, as well as its
total expenses, were below the median fee rates charged by its peer group as
determined by Lipper. Each Board has concluded that each Fund's management fee
and fee rate and overall expense ratio are reasonable compared to those of other
comparable funds.

Profitability -- The Boards considered the cost of the services provided to the
Trust and/or the Fund by the Investment Adviser and the Investment Adviser's and
its affiliates' profits relating to the management and distribution of the Fund
and the MLIM/FAM-advised funds. As part of its analysis, the Boards reviewed the
Investment Adviser's methodology in allocating its costs to the management of
the Trust and the Fund and concluded that there was a reasonable basis for the
allocation. The Boards also considered federal court decisions discussing an
investment adviser's profitability and


        MERRILL LYNCH LARGE CAP SERIES FUNDS, INC.      OCTOBER 31, 2005      55


Disclosure of Investment Advisory Agreement (concluded)

profitability levels considered to be reasonable in those decisions. The Boards
believe the Investment Adviser's profits are reasonable in relation to the
nature and quality of the services provided.

Economies of Scale -- The Boards considered the extent to which economies of
scale might be realized as the assets of the Trust and Fund increase and whether
there should be changes in the management fee rate or structure in order to
enable the Trust and the Funds to participate in these economies of scale. The
Boards determined that the current management fee structure was reasonable and
that no changes were currently necessary.

Conclusion

After the independent Directors deliberated in executive session, each entire
Board including all of the independent Directors, approved the renewal of the
existing Investment Advisory Agreements, concluding that the advisory fee was
reasonable in relation to the services provided and that a contract renewal was
in the best interests of the shareholders.

         (e)(1) The registrant's audit committee (the "Committee") has adopted
         policies and procedures with regard to the pre-approval of services.
         Audit, audit-related and tax compliance services provided to the
         registrant on an annual basis require specific pre-approval by the
         Committee. The Committee also must approve other non-audit services
         provided to the registrant and those non-audit services provided to the
         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.

         (h) The registrant's audit committee has considered and determined that
         the provision of non-audit services that were rendered to the
         registrant's investment adviser and any entity controlling, controlled
         by, or under common control with the investment adviser that provides
         ongoing services to the registrant that were not pre-approved pursuant
         to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X is compatible
         with maintaining the principal accountant's independence.
