A Letter From the President

Dear Shareholder

Equity markets produced positive results for the most recent six-month and
12-month reporting periods. The U.S. stock market, as measured by the Standard &
Poor's 500 Index, returned +6.27% for the six-month period and +22.88% for the
12-month period ended April 30, 2004.

Though equity markets enjoyed favorable returns overall, we did experience an
overdue market correction late in the period. This was largely in response to
disappointing employment news (which has improved markedly since then),
terrorist attacks in Madrid and instability in Iraq -- all of which weighed
heavily on the markets. However, despite the more recent skittishness, we still
observe substantial economic strength in the United States.

In fact, the U.S. economy has continued to benefit from 2003's significant
fiscal and monetary stimulus in the form of low interest rates and tax cuts.
This has opened the door to consumer spending, capital spending, increases in
exports and long-awaited job growth. A major shift on the employment front came
on April 2 when the Department of Labor reported the biggest monthly jobs
increase in four years. These developments have supported continued improvements
in corporate earnings -- a positive for stock markets. For its part, the Federal
Reserve Board maintained its accommodative policy stance, and is expected to
raise interest rates at a gradual pace in order to ensure the sustainability of
the current economic recovery.

The events and efforts of the past year leave us with a much stronger economy
today. Of course, markets will always fluctuate, and there are many
uncertainties -- not the least of which are geopolitical in nature -- which can
translate into negative market movements. Keeping this in mind, however, we
encourage you to revisit your portfolio and your asset allocation strategy to
ensure you are well positioned to take advantage of the opportunities that lie
ahead. Importantly, your financial advisor can help you develop a strategy most
suitable for your circumstances through all types of market and economic cycles.

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

      Despite a favorable backdrop of improving corporate earnings and economic
revitalization, an equity market correction late in the period produced a drag
on Fund performance.

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

For the six-month period ended April 30, 2004, Merrill Lynch Large Cap Value
Fund's Class A, Class B, Class C, Class I and Class R Shares had total returns
of +7.60%, +7.25%, +7.17%, +7.76% and +7.42%, respectively. While these returns
reflect positive absolute results, the Fund's relative performance trailed the
+8.15% return of the unmanaged benchmark, the Russell 1000 Value Index, for the
same period. Fund returns were competitive with the Lipper Large-Cap Value Funds
category, which posted a return of +7.62% for the same six-month period. (Funds
in this Lipper category seek long-term growth of capital by investing in
large-capitalization companies that are considered to be undervalued relative to
a major unmanaged stock index.)

Importantly, over the long-term, the Fund has outperformed its benchmark, the
Russell 1000 Value Index. Since inception on December 22, 1999 through April 30,
2004, the Fund's Class A, Class B, Class C and Class I Shares had respective
total returns of +37.54%, +33.11%, +33.01% and +39.08%, far exceeding the
+13.92% return of the Russell 1000 Value Index. The Fund's Class R Shares, since
inception (January 3, 2003) to April 30, 2004, returned +33.10% compared to the
Index return of +26.77%. (Fund results shown do not reflect sales charges and
would be lower if sales charges were included. Complete performance information
can be found on pages 6 and 7 of this report to shareholders.)

Because the Fund invests in large-capitalization stocks that represent a
significant part of the U.S. stock market, its portfolio was influenced by the
same economic and market events that affected the broader stock market during
the period. The last quarter of 2003 and the first quarter of 2004 were marked
by dramatic rises and falls in world markets, with the equity markets undergoing
a correction in the spring of 2004, despite strong economic growth and robust
corporate earnings.

What factors influenced Fund performance during the period?

The Fund invests primarily in a diversified portfolio of large cap companies
selected from securities found in the Russell 1000 Index. During the past six
months, the Portfolio was positioned in economically sensitive cyclical stocks.
Despite improving corporate earnings and economic revitalization, a combination
of interest rate fears, rising energy prices, risks to growth in China and a
destabilized U.S. dollar pushed equity prices lower late in the period. Given
the Portfolio's heightened exposure to stocks leveraged to economic recovery and
a market upturn, the correction had a greater impact on the Portfolio and
ultimately resulted in the underperformance of the Fund relative to its
benchmark index.

Stock selection in the health care, financials and industrials sectors benefited
performance during the period. On the negative side, stock selection in
information technology was a drag on performance.

At the individual stock level, the largest positive contributors to performance
were Foot Locker, Inc., DaVita, Inc., Motorola, Inc., Georgia-Pacific
Corporation and J.C. Penney Company, Inc. The largest detractors from
performance included Amkor Technology, Inc., Cypress Semiconductor Corporation,
Emulex Corporation and VERITAS Software Corporation. Underweights in Exxon Mobil
Corporation and Altria Group, Inc. also negatively affected performance.

What changes were made to the Portfolio during the period?

We increased our positions relative to the benchmark in materials, consumer
staples and energy based on our belief that stocks in these sectors would
benefit as we transition from an economic recovery to an environment of rising
interest rates. We reduced our position relative to the benchmark in
telecommunication services, given improved valuations, and in financials, based
on interest rate concerns.


4         MERRILL LYNCH LARGE CAP VALUE FUND      APRIL 30, 2004


The largest purchases during the period included The Allstate Corporation,
Lucent Technologies Inc., Norfolk Southern Corporation, Motorola, Inc.,
Fairchild Semiconductor Corporation and CIGNA Corporation. The largest sales
included CVS Corporation, Sprint Corp. (PCS), Lehman Brothers Holdings, Inc.,
Anthem, Inc. and National Semiconductor Corporation.

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

The Portfolio's largest overweights as of April 30, 2004 were in the consumer
discretionary and information technology sectors, which we believe should
benefit from strong earnings growth. The largest underweights were in
financials, which tend to underperform in periods of rising interest rates, and
telecommunication services.

Companies exhibiting good earnings momentum, earnings surprise and valuation
characteristics saw strong performance through the end of 2003. However,
relative performance for these companies deteriorated as the broad markets
turned downward in spring 2004. We remain committed to these disciplines for
stock selection, and the Portfolio ended the period positioned in cyclical
stocks that we believe should benefit as investor focus returns to the robust
corporate earnings environment. Nonetheless, given the recent equity market
correction and interest rate pressures, we are moderating our exposure to
economic sensitivity as well as reducing our exposure to lower-capitalization
securities. Our intention is to continue to reduce the interest rate sensitivity
of the Portfolio as rates continue to increase.

The Federal Funds futures market now projects a near certain hike in the Federal
Funds target rate in June with another potential increase in August. We believe
the economy is stronger than many expected at this point. Strong payroll reports
for March and April, as well as recent data from the Institute for Supply
Management survey, indicate that a sustainable economic recovery is underway,
which should continue to support consumption and other business activity. We
believe a modest increase in inflation also is underway, and our projection at
the beginning of the year that the Federal Reserve Board would double its rate
from 1% to 2% by year-end currently seems more realistic.

The equity market correction, while not a surprise, has been more significant
than expected, particularly given the boom in corporate earnings. Our view is
that there is at least one more up-leg in the equity market before the cyclical
backdrop becomes a problem. The timing of this rally will hinge on when the
Treasury market calms, the dollar stabilizes or resumes its slow decline, and
oil prices ease. Some combination of these factors should set the stage for more
focus on earnings and a better equity market. In the meantime, sluggishness in
stock prices is likely to persist. We will continue to monitor economic and
market developments in order to make the most informed decisions regarding the
Portfolio's investments.

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 more current performance
information. 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.

[LOGO] Merrill Lynch Investment Managers

Notes to Financial Statements                 Merrill Lynch Large Cap Value Fund

1. Significant Accounting Policies:

Merrill Lynch Large Cap Value Fund of Merrill Lynch Large Cap Series Funds, Inc.
(the "Fund") is registered under the Investment Company Act of 1940, as amended,
as a diversified mutual fund. The Fund seeks to achieve its investment objective
by investing all of its assets in Master Large Cap Value Portfolio (the
"Portfolio"), which is a portfolio of Master Large Cap Series Trust that has the
same investment objective as the Fund. The value of the Fund's investment in the
Portfolio reflects the Fund's proportionate interest in the net assets of the
Portfolio. The performance of the Fund is directly affected by the performance
of the Portfolio. The financial statements of the Portfolio, including the
Schedule of Investments, are included elsewhere in this report and should be
read in conjunction with the Fund's financial statements. The Fund's financial
statements are prepared in conformity with accounting principles generally
accepted in the United States of America, which may require the use of
management accruals and estimates. Actual results may differ from these
estimates. These unaudited financial statements reflect all adjustments, which
are, in the opinion of management, necessary to a fair statement of the results
for the interim period presented. All such adjustments are of a normal,
recurring nature. The percentage of the Portfolio owned by the Fund at April 30,
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. Income, expenses (other than
expenses attributable to a specific class) and realized and unrealized gains and
losses on investments are allocated daily to each class based on its relative
net assets. The following is a summary of significant accounting policies
followed by the Fund.

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

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

(c) Income taxes -- It is the Fund's policy to comply with the requirements of
the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to shareholders. Therefore,
no Federal income tax provision is required. Under the applicable foreign tax
law, withholding taxes may be imposed on interest, dividends and capital gains
at various rates.

(d) Prepaid registration fees -- Prepaid registration fees are charged to
expense as the related shares are issued.

(e) Dividends and distributions -- Dividends and distributions paid by the Fund
are recorded on the ex-dividend dates.

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

2. Transactions with Affiliates:

The Fund has entered into an Administration Agreement with Fund Asset
Management, L.P. ("FAM"). The general partner of FAM is Princeton Services, Inc.
("PSI"), an indirect, wholly-owned subsidiary of Merrill Lynch & Co., Inc. ("ML
& Co."), which is the limited partner. The Fund pays a monthly fee at an annual
rate of .25% of the Fund's average daily net assets for the performance of
administrative services (other than investment advice and related portfolio
activities) necessary for the operation of the Fund.

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

Pursuant to the Distribution Plans adopted by the Fund in accordance with Rule
12b-1 under the Investment Company Act of 1940, the Fund pays the Distributor
ongoing account maintenance and distribution fees. The fees are accrued daily
and paid monthly at annual rates based upon the average daily net assets of the
shares as follows:

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

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

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 six months ended April 30, 2004, FAMD earned underwriting discounts and
MLPF&S earned dealer concessions on sales of the Fund's Class A and Class I

sales charges of $164,377 and $6,569 relating to transactions in Class B and
Class C Shares, respectively. Furthermore, MLPF&S received contingent deferred
sales charges of $24,822 relating to transactions subject to front-end sales
charge waivers in Class A Shares.

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

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

Notes to Financial Statements                   Master Large Cap Value Portfolio

1. Significant Accounting Policies:

Master Large Cap Value Portfolio (the "Portfolio") is part of Master Large Cap
Series Trust (the "Trust"). The Trust is registered under the Investment Company
Act of 1940, as amended, and is organized as a Delaware statutory trust. The
Declaration of Trust permits the Trustees to issue nontransferable interests in
the Portfolio, subject to certain limitations. The Portfolio's financial
statements are prepared in conformity with accounting principles generally
accepted in the United States of America, which may require the use of
management accruals and estimates. Actual results may differ from these
estimates. These unaudited financial statements reflect all adjustments, which
are, in the opinion of management, necessary to a fair statement of the results
for the interim period presented. All such adjustments are of a normal,
recurring nature. The following is a summary of significant accounting policies
followed by the Portfolio.

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

Options written are valued at the last sale price in the case of exchange-traded
options or, in the case of options traded in the OTC market, the last ask price.
Options purchased are valued at their last sale price in the case of
exchange-traded options or, in the case of options traded in the OTC market, the
last bid price. Swap agreements are valued daily based upon quotations from
market makers. Financial futures contracts and options thereon, which are traded
on exchanges, are valued at their last sale price as of the close of such
exchanges. Obligations with remaining maturities of 60 days or less are valued
at amortized cost unless the Investment Adviser believes that this method no
longer produces fair valuations.

Repurchase agreements are valued at cost plus accrued interest. The Portfolio
employs pricing services to provide certain securities prices for the Portfolio.
Securities and assets for which market quotations are not readily available are
valued at fair value as determined in good faith by or under the direction of
the Board of Trustees of the Portfolio, including valuations furnished by the
pricing services retained by the Portfolio, which may use a matrix system for
valuations. The procedures of a pricing service and its valuations are reviewed
by the officers of the Portfolio under the general supervision of the
Portfolio's Board of Trustees. Such valuations and procedures will be reviewed
periodically by the Board of Trustees of the Portfolio.

Generally, trading in foreign securities, as well as U.S. government securities
and money market instruments, is substantially completed each day at various
times prior to the close of business on the New York Stock Exchange ("NYSE").
The values of such securities used in computing the net assets of the
Portfolio's shares are determined as of such times. Foreign currency exchange
rates also are generally determined prior to the close of business on the NYSE.
Occasionally, events affecting the values of such securities and such exchange
rates may occur between the times at which they are determined and the close of
business on the NYSE that may not be reflected in the computation of the
Portfolio's net assets. If events (for example, a company announcement, market
volatility or a natural disaster) occur during such periods that are expected to
materially affect the value of such securities, those securities may be valued
at their fair value as determined in good faith by the Portfolio's Board of
Trustees or by the Investment Adviser using a pricing service and/or procedures
approved by the Portfolio's Board of Trustees.

(b) Derivative financial instruments -- The Portfolio may engage in various
portfolio investment strategies both to increase the return of the Portfolio and
to hedge, or protect, its exposure to interest rate movements and movements in
the securities markets. Losses may arise due to changes in the value of the
contract or if the counterparty does not perform under the contract.

o     Financial futures contracts -- The Portfolio may purchase or sell
      financial futures contracts and options on such futures contracts. Futures
      contracts are contracts for

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

      delayed delivery of securities at a specific date and at a specific price
      or yield. Upon entering into a contract, the Portfolio deposits and
      maintains as collateral such initial margin as required by the exchange on
      which the transaction is effected. Pursuant to the contract, the Portfolio
      agrees to receive from or pay to the broker an amount of cash equal to the
      daily fluctuation in value of the contract. Such receipts or payments are
      known as variation margin and are recorded by the Portfolio as unrealized
      gains or losses. When the contract is closed, the Portfolio records a
      realized gain or loss equal to the difference between the value of the
      contract at the time it was opened and the value at the time it was
      closed.

o     Options -- The Portfolio may purchase and write call and put options. When
      the Portfolio writes an option, an amount equal to the premium received by
      the Portfolio is reflected as an asset and an equivalent liability. The
      amount of the liability is subsequently marked to market to reflect the
      current market value of the option written. When a security is purchased
      or sold through an exercise of an option, the related premium paid (or
      received) is added to (or deducted from) the basis of the security
      acquired or deducted from (or added to) the proceeds of the security sold.
      When an option expires (or the Portfolio enters into a closing
      transaction), the Portfolio realizes a gain or loss on the option to the
      extent of the premiums received or paid (or a gain or loss to the extent
      that the cost of the closing transaction exceeds the premium paid or
      received).

      Written and purchased options are non-income producing investments.

o     Forward foreign exchange contracts -- The Portfolio may enter into forward
      foreign exchange contracts as a hedge against either specific transactions
      or portfolio positions. The contract is marked-to-market daily and the
      change in market value is recorded by the Portfolio as an unrealized gain
      or loss. When the contract is closed, the Portfolio records a realized
      gain or loss equal to the difference between the value at the time it was
      opened and the value at the time it was closed.

o     Foreign currency options and futures -- The Portfolio may also purchase or
      sell listed or over-the-counter foreign currency options, foreign currency
      futures and related options on foreign currency futures as a short or long
      hedge against possible variations in foreign exchange rates. Such
      transactions may be effected with respect to hedges on non-U.S. dollar
      denominated securities owned by the Portfolio, sold by the Portfolio but
      not yet delivered, or committed or anticipated to be purchased by the
      Portfolio.

(c) Foreign currency transactions -- Transactions denominated in foreign
currencies are recorded at the exchange rate prevailing when recognized. Assets
and liabilities denominated in foreign currencies are valued at the exchange
rate at the end of the period. Foreign currency transactions are the result of
settling (realized) or valuing (unrealized) assets or liabilities expressed in
foreign currencies into U.S. dollars. Realized and unrealized gains or losses
from investments include the effects of foreign exchange rates on investments.

(d) Income taxes -- The Portfolio is considered as a "pass through" entity for
Federal income tax purposes. As such, each investor in the Portfolio is treated
as owner of its proportionate share of the net assets, income, expenses and
realized and unrealized gains and losses of the Portfolio. Therefore, no Federal
income tax provision is required. It is intended that the Portfolio's assets
will be managed so an investor in the Portfolio can satisfy the requirements of
subchapter M of the Internal Revenue Code.

(e) Security transactions and investment income -- Security transactions are
accounted for on the date the securities are purchased or sold (the trade
dates). Realized gains and losses on security transactions are determined on the
identified cost basis. Dividend income is recorded on the ex-dividend dates.
Dividends from foreign securities where the ex-dividend date may have passed are
subsequently recorded when the Portfolio has determined the ex-dividend date.
Interest income is recognized on the accrual basis.

(f) Securities lending -- The Portfolio may lend securities to financial
institutions that provide cash or securities issued or guaranteed by the U.S.
government as collateral, which will be maintained at all times in an amount
equal to at least 100% of the current market value of the loaned securities. The
market value of the loaned securities is determined at the close of business of
the Portfolio and any additional required collateral is delivered to the
Portfolio on the next business day. Where the Portfolio receives securities as
collateral for the loaned securities, it receives a fee from the borrower. The
Portfolio typically receives the income on the loaned securities, but does not
receive the income on the collateral. Where the Portfolio receives cash
collateral, it may invest

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

such collateral and retain the amount earned on such investment, net of any
amount rebated to the borrower. Loans of securities are terminable at any time
and the borrower, after notice, is required to return borrowed securities within
five business days. The Portfolio may pay reasonable finder's, lending agent,
administrative and custodial fees in connection with its loans. In the event
that the borrower defaults on its obligation to return borrowed securities
because of insolvency or for any other reason, the Portfolio could experience
delays and costs in gaining access to the collateral. The Portfolio also could
suffer a loss where the value of the collateral falls below the market value of
the borrowed securities, in the event of borrower default or in the event of
losses on investments made with cash collateral.

2. Investment Advisory Agreement and Transactions with Affiliates:

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

FAM is responsible for the management of the Portfolio's investments and
provides the necessary personnel, facilities, equipment and certain other
services necessary to the operations of the Portfolio. For such services, the
Portfolio pays a monthly fee at an annual rate of .50% of the average daily
value of the Portfolio's net assets. FAM has entered into a Sub-Advisory
Agreement with Merrill Lynch Asset Management U.K. 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.

For the six months ended April 30, 2004, the Portfolio reimbursed FAM $5,496 for
certain accounting services.

The Portfolio has received an exemptive order from the Securities and Exchange
Commission permitting it to lend portfolio securities to Merrill Lynch, Pierce,
Fenner & Smith Incorporated ("MLPF&S"), a subsidiary of ML & Co., or its
affiliates. As of April 30, 2004, the Portfolio lent securities with a value of
$15,382,882 to MLPF&S or its affiliates. Pursuant to that order, the Portfolio
also has retained Merrill Lynch Investment Managers, LLC ("MLIM, LLC"), an
affiliate of FAM, as the securities lending agent for a fee based on a share of
the returns on investment of cash collateral. MLIM, LLC may, on behalf of the
Portfolio, invest cash collateral received by the Portfolio for such loans,
among other things, in a private investment company managed by MLIM, LLC or in
registered money market funds advised by FAM or its affiliates. For the six
months ended April 30, 2004, MLIM, LLC received $19,576 in securities lending
agent fees.

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

3. Investments:

Purchases and sales of investments, excluding short-term securities, for the six
months ended April 30, 2004 were $456,970,444 and $357,994,915, respectively.

- --------------------------------------------------------------------------------
                                                 Realized           Unrealized
                                                  Gains            Appreciation

Long-term investments ................        $ 50,172,155         $ 79,115,222
                                              ---------------------------------
Total ................................        $ 50,172,155         $ 79,115,222
                                              =================================

As of April 30, 2004, net unrealized appreciation for Federal income tax
purposes aggregated $74,238,569, of which $90,567,730 related to appreciated
securities and $16,329,161 related to depreciated securities. At April 30, 2004,
the aggregate cost of investments for Federal income tax purposes was
$685,777,432.

4. Short-Term Borrowings:

The Portfolio, along with certain other funds managed by FAM and its affiliates,
is party to a $500,000,000 credit agreement with Bank One, N.A. and certain
other lenders. The Portfolio may borrow under the credit agreement to fund
investor withdrawals and for other lawful purposes other than for leverage. The
Portfolio may borrow up to the maximum amount allowable under the Portfolio's
current prospectus and statement of additional information, subject to various
other legal, regulatory or contractual limits. The Portfolio pays a commitment
fee of .09% per annum based on the Portfolio's pro rata share of the unused
portion of the facility. Amounts borrowed under the facility bear interest at a
rate equal to, at each fund's election, the Federal Funds rate plus .50% or a
base rate as determined by Bank One, N.A. On November 28, 2003, the credit
agreement was renewed for one year under the same terms. The Portfolio did not
borrow under the facility during the six months ended April 30, 2004.
