MERRILL LYNCH INTERNATIONAL VALUE FUND, DECEMBER 31, 2003



A Letter From the President


Dear Shareholder

In my 35 years in the asset management business, 2003 was among the
more memorable. The year, which opened with global economic
uncertainty and a dismal continuation of a three-year equity market
slump, vigorously reversed course in the months that followed. To be
sure, 2003 came in like a lamb and went out like a lion. Or, some
might suggest, the year started as a bear and ended as a bull.

Notably, the U.S. stock market exceeded the expectations of even the
optimistic investor, with the S&P 500 Index and the Nasdaq posting
respective 12-month returns of +28.68% and +50.01% as of December
31, 2003. Notwithstanding the impressive results, several foreign
stock markets eclipsed the U.S. market returns in dollar terms.
Overall, the Morgan Stanley Capital International (MSCI) World
Index, which measures the performance of equity markets in 23
developed countries worldwide, returned +33.11% over the past 12
months. Several emerging markets also fared particularly well, with
Thailand's equity market up 139% and Brazil's up 131% for the year,
as measured by MSCI.

As we begin a new year, it is heartening to note that a global
economic expansion appears to be underway. In 2003, the U.S. economy
benefited from stimulative monetary and fiscal policy, improving
corporate profits and tightening credit spreads. Gross domestic
product (GDP) growth rallied from a dismal 1.4% in the first quarter
of the year to an extraordinary 8.2% in the third quarter. In
Europe, the central bank initiated a more active monetary policy in
an effort to rouse economic growth. The economies of several Asian
countries experienced strong growth in 2003. China, in particular,
is expected to grow at an annualized rate of 8% for 2003-2004.
Encouragingly, Japan, the world's second-largest economy, finally
appeared to be emerging from a long period of deflation. Elsewhere,
Latin America benefited from a combination of declining global risk
and relative political stability. It has been a long road for equity
investors, but coming into 2004, the events and efforts of 2003
leave us with stronger economies around the world.

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

We thank you for trusting Merrill Lynch Investment Managers with
your investment assets, and we look forward to serving you in the
New Year and beyond.


Sincerely,



(Terry K. Glenn)

President and Trustee

A Discussion With Your Fund's Portfolio Manager


The Fund provided strong absolute and relative returns for the
period, with favorable stock selection having the greatest positive
impact on results.


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

For the six-month period ended December 31, 2003, Merrill Lynch
International Value Fund's Class A, Class B, Class C, Class I and
Class R Shares had total returns of +27.23%, +26.77%, +26.72%,
+27.39% and +27.22%, respectively. (Fund results shown do not
reflect sales charges and would be lower if sales charges were
included. Complete performance information can be found on pages
6 - 8 of this report to shareholders.) This compared to returns of
+26.59% for the unmanaged benchmark Morgan Stanley Capital
International Europe, Australasia, Far East (MSCI EAFE) Index and
+29.82% for the unmanaged MSCI EAFE Value Index for the same period.
Fund performance exceeded the +23.93% average return of the Lipper
International Funds category for the same six-month period. (Funds
in this Lipper category invest in securities with primary trading
markets outside the United States.)

The year 2003 began with a three-month bear market trend followed by
a nine-month equity market rally that was led by lower-quality
issues with little earnings. The type of value stocks that we
consider for our shareholders--those with some earnings, cash flow
and dividends--generally were laggards during this rally. The
principal driver of Fund performance in 2003 as a whole was stock
selection, whereas sector and geographic allocation added little
value. Two of our positions, Germany's DePfa Bank PLC and Dutch
employment agency Vedior NV, returned more than 100% in local
currency terms during the year. Currency strength meant that these
returns were significantly enhanced when translated into U.S. dollar
terms. These remarkable returns point to the extent of the extreme
market conditions during the year.

The Fund's strong relative and absolute performance during the
six-month period also is attributed to stock selection, which was
particularly favorable in the Netherlands, France and Japan. Our
holdings in Netherlands-based Vedior, Japanese computer games
company Namco Ltd. and brewer Asahi Breweries Limited, and French
metals company Pechiney SA were the top contributors to performance
for the period. Stocks that disappointed included French car company
PSA Peugeot Citroen, Anglo-Dutch oil company Shell Transport &
Trading Company, British engineering company Smiths Industries PLC
and Allied Irish Banks PLC.

Also contributing positively to performance in the six-month period
were our overweight positions in economically cyclical sectors, such
as energy, materials, commercial services and diversified
financials. At the same time, maintaining underweightings in highly
rated sectors, such as technology hardware and media, had a modest
positive effect on performance.


What changes were made to the portfolio during the period?

In 2003, we made several considerable changes to the portfolio. As
many of the stocks we owned reached our price target, we sold those
holdings and invested the proceeds in new positions. Overall, the
portfolio's turnover for the year was higher than normal, again
pointing to the extreme market environment. Having said that, our
strategy of concentrating on attractive companies with low
valuations and a mild tilt toward economic recovery remained
constant during the six-month period.

The main transactions during the six months were all the result of
bottom-up stock picking, based on our assessment of whether the
stocks were trading at bargain prices. Major additions to the
portfolio included mobile phone operator Vodafone Group PLC,
consumer electricals retailer Kesa Electricals PLC, insurer Mitsui
Sumitomo Insurance Company, Limited, car manufacturer Toyota Motor
Corporation, and French bank Credit Agricole SA. All were added on
the grounds of attractive valuations. In contrast, our positions in
drug giant GlaxoSmithKline PLC, U.K. bank Barclays PLC, electronics
manufacturer Motion Engineering Inc., German bank DePfa and Dutch
financial conglomerate Fortis were all trimmed as valuations reached
levels that were no longer appealing.



MERRILL LYNCH INTERNATIONAL VALUE FUND, DECEMBER 31, 2003



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

The portfolio maintained its position in inexpensive stocks, with a
bias toward a continuation of global economic recovery. At December
31, 2003, we were overweight relative to the benchmark in the more
economically sensitive sectors, such as materials, energy and
automotive, and underweight in telecommunication services,
pharmaceuticals and capital goods.

We expect global earnings to continue their rise in 2004, although
perhaps at a slower pace than in 2003. As nominal gross domestic
product accelerates, the key driver of earnings growth is likely to
shift from margin enhancement through cost cutting to top-line
growth. Our analysis shows that earnings are still cyclically
depressed and are likely to rise as capacity utilization increases.

The earnings seasons in the United States, Europe and Japan have
provided further reason for encouragement. Not only have earnings
exceeded market expectations in all three regions, but earnings
guidance is beginning to improve. In 2003, earnings expectations
were upgraded dramatically from the depressed levels at the start of
the year, when fear and depression gripped the markets. While we
believe further upgrades are probable, the pace of earnings momentum
is not likely to be sustained. The initial spectacular rebound in
reported earnings was supported by the virtual cessation of write-
offs, while market expectations for 2004 are already very positive.
As a result, some slowdown in the pace of earnings growth is
inevitable in 2004.

While the recent equity market rally has taken absolute valuations
back above their long-run averages, valuations remain close to their
historic means and are not yet sending a strong signal. Equities
still appear attractively valued relative to real government bond
yields, whether on an equity risk premium or implied earnings growth
basis. Nevertheless, the compelling valuation case that appeared
early in the year has largely disappeared. In the United States, the
gap has closed, while in Europe, particularly the United Kingdom,
equities still possess attractive long-term return potential
relative to bonds. Global valuations have converged significantly,
with all major large cap markets trading within a relatively narrow
price/earnings ratio range.

Asian valuations remained attractive as of period end. The Japanese
market, in our opinion, is bifurcated. We believe the blue chip
stocks are still attractive, while the valuations of many low-
quality stocks appear excessive. In our view, improving economic
performance both in the United States and internationally will
result in higher stock market values ahead.

Performance Data


About Fund Performance


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

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

* Class B Shares are subject to a maximum contingent deferred sales
charge of 4% if redeemed during the first two years, decreasing to
3% for each of the next two years and decreasing 1% each year
thereafter to 0% after the sixth year. In addition, Class B Shares
are subject to a distribution fee of 0.75% and an account
maintenance fee of 0.25%. These Shares automatically convert to
Class A Shares after approximately eight years.

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

* Class I Shares  incur a maximum initial sales charge of 5.25% and
bear no ongoing distribution and account maintenance fees. Class I
Shares are available only to eligible investors.

* Class R Shares do not incur a maximum sales charge (front-end
load) or deferred sales charge. These shares are subject to a
distribution fee of 0.25% and an account maintenance fee of
0.25%.Class R Shares are available only to certain retirement plans.

None of the past results shown should be considered a representation
of future performance. 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 gains distributions at net asset value on the
ex-dividend date. Investment return and principal value of shares
will fluctuate so that shares, when redeemed, may be worth more or
less than their original cost. Dividends paid to each class of
shares will vary because of the different levels of account
maintenance, distribution and transfer agency fees applicable to the
classes, which are deducted from the income available to be paid to
shareholders. The Fund's investment adviser voluntarily paid annual
operating expenses in excess of 1.0% of average Class I net assets
until 3/1/99, when it removed/discontinued capping expenses. Without
such expense cap, the Fund's Class I performance would have been
lower.

MERRILL LYNCH INTERNATIONAL VALUE FUND, DECEMBER 31, 2003



Notes to Financial Statements


1. Significant Accounting Policies:
Merrill Lynch International Value Fund (the "Fund") is a fund of
Mercury Funds II (the "Trust"). The Trust is registered under the
Investment Company Act of 1940, as amended, as a diversified, open-
end management investment company, which is organized as a
Massachusetts business trust. The Fund's financial statements are
prepared in conformity with accounting principles generally accepted
in the United States of America, which may require the use of
management accruals and estimates. These unaudited financial
statements reflect all adjustments, which are, in the opinion of
management, necessary to a fair statement of the results for the
interim period presented. All such adjustments are of a normal,
recurring nature. The Fund offers multiple classes of shares. Class
A and Class I Shares are sold with a front-end sales charge. Class B
and Class C Shares 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 Shares have certain
voting rights with respect to Class A distribution expenditures).
Income, expenses (other than expenses attributable to a specific
class) and realized and unrealized gains and losses on investments
and foreign currency transactions are allocated daily to each class
based on its relative net assets. The following is a summary of
significant accounting policies followed by the Fund.

(a) Valuation of investments--Equity securities that are held by the
Fund 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 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 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
Fund employs pricing services to provide certain securities prices
for the Fund. 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 the Fund, 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 and money market instruments, is substantially completed
each day at various times prior to the close of business on the New
York Stock Exchange ("NYSE"). The values of such securities used in
computing the net asset value of the Fund'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 Fund's net asset value. If events (for example, a
company announcement, market volatility or a natural disaster) occur
during such periods that are expected to materially affect the value
of such securities, those securities may be valued at their fair
value as determined in good faith by the 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.



MERRILL LYNCH INTERNATIONAL VALUE FUND, DECEMBER 31, 2003



Notes to Financial Statements (continued)


(b) Derivative financial instruments--The Fund may engage in various
portfolio investment strategies both to increase the return of the
Fund 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.

* Forward foreign exchange contracts--The Fund 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
Fund as an unrealized gain or loss. When the contract is closed, the
Fund 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.

(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--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 its 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.

(e) Security transactions and investment income--Security
transactions are recorded on the dates the transactions are entered
into (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 Fund has determined the ex-dividend
date. Interest income is recognized on the accrual basis.

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

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

(h) Expenses--Common expenses incurred by the Trust are allocated
among the funds based upon: (i) relative net assets; (ii) as
incurred on a specific identification basis; or (iii) evenly among
the funds, depending on the nature of the expenditure.

(i) Securities lending--The Fund 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 Fund and
any additional required collateral is delivered to the Fund on the
next business day. Where the Fund receives securities as collateral
for the loaned securities, it collects a fee from the borrower. The
Fund typically receives the income on the loaned securities but does
not receive the income on the collateral. Where the Fund 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 Fund 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 Fund could experience delays and costs in gaining access
to the collateral. The Fund 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.



MERRILL LYNCH INTERNATIONAL VALUE FUND, DECEMBER 31, 2003



Notes to Financial Statements (continued)


(j) Custodian bank--The Fund recorded an amount payable to the
custodian bank which resulted from a failed foreign exchange
contract.


2. Investment Advisory Agreement and Transactions with Affiliates:
The Trust has entered into an Investment Advisory Agreement for the
Fund 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 Fund's
investments and provides the necessary personnel, facilities,
equipment and certain other services necessary to the operations of
the Fund. For such services, the Fund pays a monthly fee at an
annual rate of .75% of the average daily value of the Fund's net
assets.

FAM has entered into Sub-Advisory agreements for the Fund with
Merrill Lynch Investment Managers International Limited and Merrill
Lynch Asset Management U.K. Limited ("MLAM U.K."), affiliated
investment advisers that are indirect subsidiaries of ML & Co.
The Sub-Advisory arrangements are for investment research,
recommendations and other investment-related services to be provided
to the Fund. There is no increase in aggregate fees paid by the Fund
for these services.

The Trust on behalf of the Fund has also entered into a Distribution
Agreement and Distribution Plans with FAM Distributors, Inc. ("FAMD"
or the "Distributor"), an indirect, 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 on-going account
maintenance and distribution fees. The fees are accrued daily and
paid monthly at the annual rates based upon the average daily net
assets of the shares as follows:


                                  Account
                              Maintenance       Distribution
                                      Fee                Fee

Class A                              .25%                 --
Class B                              .25%               .75%
Class C                              .25%               .75%
Class R                              .25%               .25%


Pursuant to a sub-agreement with the Distributor, selected dealers
also provide account maintenance and distribution services to the
Fund. The ongoing account maintenance fee compensates the
Distributor and selected dealers for providing account maintenance
services to Class A, Class B, Class C and Class R shareholders. The
ongoing distribution fee compensates the Distributor and selected
dealers for providing shareholder and distribution-related services
