These financial statements have been prepared without audit. In the opinion of
management, the financial statements contain all adjustments (consisting of only

results of its operations for the three months ended March 31, 2001 and 2000.
However, the operating results for the interim periods may not be indicative of
the results expected for the full year.

Certain information and footnote disclosures normally included in annual
financial statements prepared in accordance with accounting principles
generally accepted in the United States of America have been omitted. It is
suggested that these financial statements be read in conjunction with the

3.   FAIR VALUE AND OFF-BALANCE SHEET RISK

The Partnership invests all of its assets in ML Multi Manager Portfolio LLC
("MM LLC"). Accordingly, the Partnership is invested indirectly in derivative
instruments, but does not itself hold any derivative instrument positions. The
application of the provisions of Statement of Financial Accounting Standards
No. 133 as amended by SFAS No. 137, and further amended by SFAS No. 138, did
not have a significant effect on the financial statements of the Partnership.

MARKET RISK

Derivative financial instruments involve varying degrees of off-balance sheet
market risk. Changes in the level or volatility of interest rates, foreign
currency exchange rates or the market values of the underlying financial
instruments or commodities underlying such derivative instruments frequently
result in changes in the Partnership's net unrealized profit on such derivative
instruments with respect to Partnership assets invested in MM LLC, as reflected
in the Statements of Financial Condition of the MM LLC. The Partnership's
exposure to market risk is influenced by a number of factors, including the
relationships among the derivative instruments held by MM LLC, as well as
the volatility and liquidity of such markets in which such derivative
instruments are traded.

                                       6
<PAGE>

The General Partner, Merrill Lynch Investment Partners Inc. ("MLIP"), has
procedures in place intended to control market risk exposure, although there
can be no assurance that they will, in fact, succeed in doing so. These
procedures focus primarily on monitoring the trading of the Advisors selected
from time to time for MM LLC, and include calculating the Net Asset Value of
the Advisors' respective MM LLC accounts as of the close of business on each
day and reviewing outstanding positions for over-concentrations both on an
Advisor-by-Advisor and on an overall Partnership basis. While MLIP does not
itself intervene in the markets to hedge or diversify the Partnership's market
exposure, through MM LLC, MLIP may urge Advisors to reallocate positions, or
itself reallocate Partnership assets among Advisors through MM LLC (although
typically only as of the end of a month) in an attempt to avoid
over-concentration. However, such interventions are unusual. Except in cases in
which it appears that an Advisor has begun to deviate from past practice and
trading policies or to be trading erratically, MLIP's basic risk control
procedures consist simply of the ongoing process of advisor monitoring and
selection, with the market risk controls being applied by the Advisors
themselves.

CREDIT RISK

The risks associated with exchange-traded contracts are typically perceived to
be less than those associated with over-the-counter (non-exchange-traded)
transactions, because exchanges typically (but not universally) provide
clearinghouse arrangements in which the collective credit (in some cases limited
in amount, in some cases not) of the members of the exchange is pledged to
support the financial integrity of the exchange. In over-the-counter
transactions, on the other hand, traders must rely solely on the credit of their
respective individual counterparties. Margins, which may be subject to loss in
the event of a default, are generally required in exchange trading, and
counterparties may require margin in the over-the-counter markets.

The Partnership, through MM LLC, has credit risk in respect of its
counterparties and brokers, but attempts to mitigate this risk by dealing almost
exclusively with Merrill Lynch entities as clearing brokers.

The Partnership, through MM LLC, in its normal course of business, enters into
various contracts, with Merrill Lynch Futures ("MLF") acting as its commodity
broker. Pursuant to the brokerage agreement with MLF (which includes a netting
arrangement), to the extent that such trading results in receivables from and
payables to MLF, these receivables and payables are offset and reported as a
net receivable or payable in the financial statements of MM LLC in the Equity
in commodity futures trading accounts in the Statements of Financial Condition.

Performance Summary

All of the Partnership's assets are invested in MM LLC. The Partnership
recognizes trading profits or losses as an investor in MM LLC. The following
commentary describes the trading results of MM LLC.

January 1, 2001 to March 31, 2001

Trading in the interest rate sector was highly profitable for the Partnership
during the quarter. Long positions in the Euro resulted in gains in January.
The impact of the weakening U.S. economy and the Federal Reserve's move to cut
interest rates was felt throughout the interest rate futures market. Euro
futures contracts rose dramatically since December 2000. Euro-yen and Euro-bund
cross futures trading produced gains for the sector.

                                      7

Agricultural trading was profitable despite losses sustained early in the
quarter. During January, the agricultural sector faced weak grain and oilseed
prices. Excellent growing weather in the U.S., Argentina and Brazil, concerns
about U.S. export potential and inventories at historically high levels kept
the markets on the defensive. Contract lows in cotton produced gains for
short positions. The cotton market sank to a 15 year low as a result of short
supply and increased demand. Potential increased planting paired with a drop
in demand forced prices lower.

Currency trading resulted in gains for the Partnership. Losses were realized
during January and February on long Euro and Swiss franc trading. After
rallying from a low of 82--83 cents to 96 cents, the Euro corrected back to
the 90 cent level, despite strong fundamentals. This resulted in losses for
the Partnership's long positions. The sector rebounded strongly in March on
substantial gains from short Japanese yen positions.

Trading in the metals markets was successful. Losses from short silver
positions were sustained in January as silver had minor technical run as it
reached it's four month high. Short silver positions were profitable in
February as silver prices reversed its earlier trend and declined as the
market was generally weak and on gold's failure to rally weighed on the
market. March was a volatile trading month as another attempted gold rally
failed, resulting in gains in short positions.

Stock index trading was moderately successful despite uncertainty in equity
markets. Short S&P 500 and NASDAQ positions resulted in gains as global
equity markets remain caught between negative news about earnings and the
potential positive effects of further monetary easing.

Energy trading was the only unprofitable sector during the quarter. Natural
gas prices pulled back in January after rallying during the last few months,
resulting in losses. Crude oil prices were driven lower by both a seasonal
downturn in global oil usage and heavier than normal refinery maintenance
work, reducing the demand. Short natural gas positions were unprofitable in
March on concerns over supply availability.

January 1, 2000 to March 31, 2000

Energy trading was profitable for the quarter due to long crude oil and
unleaded gas positions. Despite the possibility of OPEC increasing oil
production by 5%, crude oil prices continued to rise as such a hike would
still leave oil inventories at levels much below normal during the balance of
the year. Prices began to decline in mid-March as Iran backed down from its
position on the point of "no increase" and again later in the month as OPEC
announced a production increase of 1.716 million barrels per day offsetting
some gains from the previous two months.

Stock Index trading was profitable for the quarter. During the month of
January, the Hang Seng Index found market conditions to be difficult. However
stock index trading returned in February and March with gains in positions in
CAC 40 Euro futures, DAX German Stock Index and long S&P 500 positions
resulted in gains as investors focused more on value stocks near the end of
the quarter.

Metals trading alternated from profitable to unprofitable during the quarter.
In January gains in aluminum positions outweighed losses in zinc and copper,
however losses in aluminum and gold positions outweighed gains in nickel
positions during February. In March, metals trading was slightly profitable
as gains in silver positions outweighed losses in zinc and copper.

Short Swiss franc and Euro positions launched the quarter with gains after
officials from the Group of Seven met and failed to express concern about the
low levels of the European currency, however the positions were unprofitable
in February offsetting gains in Japanese yen positions. Short Euro positions
then bounced back in March but were outweighed by losses in Japanese yen and
British pound positions.

Agriculture trading resulted in losses for the quarter. In January and
February, gains in sugar positions were outweighed by losses in corn
positions. In March, corn positions were profitable as prices rose, but were
outweighed by unprofitable soyoil and sugar positions. Corn prices fluctuated
as changes in weather forecasts occurred throughout the quarter.

Short Eurodollar trading was profitable as the currency continued to decline
in January. The European Union ministers blamed the currency's slide in
January on rapid U.S. growth and fears that the Federal Reserve will increase
U.S. interest rates. These profits were far outweighed by losses in the
Japanese 10-year bond, U.S. 10-year Treasury note positions and long U.S.
Treasury positions as the yield curve fluctuated widely during the quarter.
