      In the opinion of management, the financial statements contain all
      adjustments necessary to present fairly the financial position of ML
      Winton FuturesAccess LLC (the "Fund") as of June 30, 2005, and the results
      of its operations for the period February 1, 2005 (commencement of
      operations) to June 30, 2005. However, the operating results for the
      interim period may not be indicative of the results for the period ending
      December 31, 2005.

      Certain information and footnote disclosures normally included in annual
      financial statements prepared in accordance with accounting principles

3.    FAIR VALUE AND OFF-BALANCE SHEET RISK

      The nature of this Fund has certain risks, which cannot be presented on
      the financial statements. The following summarizes some of those risks.

      MARKET RISK

      Derivative 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 financial instruments
      or commodities underlying such derivative instruments frequently results
      in changes in the Fund's net unrealized profit on such derivative
      instruments as reflected in the Statement of Financial Condition. The
      Fund's exposure to market risk is influenced by a number of factors,
      including the relationships among the derivative instruments held by the
      Fund as well as the volatility and liquidity of the markets in which the
      derivative instruments are traded.

                                        5

      Merrill Lynch Alternative Investments LLC ("MLAI"), the Sponsor of the
      Fund, 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
      Winton Capital Management Limited ("Winton"), the trading advisor,
      calculating the Net Asset Value of the Fund as of the close of business on
      each day and reviewing outstanding positions for over-concentrations.
      While MLAI does not itself intervene in the markets to hedge or diversify
      the Fund's market exposure, MLAI may urge Winton to reallocate positions
      in an attempt to avoid over-concentrations. However, such interventions
      are expected to be unusual. It is expected that MLAI's basic risk control
      procedures will consist simply of the ongoing process of advisor
      monitoring, with the market risk controls being applied by Winton itself.

      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 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 also require margin
      in the over-the-counter markets.

      The credit risk associated with these instruments from counterparty
      nonperformance is the net unrealized profit, if any, included in the
      Statement of Financial Condition. The Fund attempts to mitigate this risk
      by dealing exclusively with Merrill Lynch entities as clearing brokers.

      The Fund, in its normal course of business, enters into various contracts,
      with Merrill Lynch Pierce Fenner & Smith Inc. ("MLPF&S") acting as its
      commodity broker. Pursuant to the brokerage arrangement with MLPF&S (which
      includes a netting arrangement), to the extent that such trading results
      in receivables from and payables to MLPF&S, these receivables and payables
      are offset and reported as a net receivable or payable and included in
      equity from commodity futures trading accounts in the Statement of
      Financial Condition.

Performance Summary

FEBRUARY 1, 2005 TO JUNE 30, 2005

February 1, 2005 to March 31, 2005

The Fund posted a gain for the first quarter of 2005. Profits were recorded in
financials with commodities posting mixed returns. The largest profits were
recorded in equities which rallied as strong gains in oil and mining stocks
dominated index returns. Solid gains were posted in short-term rates against
small losses in bonds as the yield curve finally steepened after Alan Greenspan,
U.S. Federal Reserve Chairman, testified before Congress about the "conundrum"
posed by the decline in forward rates. Modest gains were made in currencies as
the U.S. dollar continued to weaken over concerns about the huge U.S. current
account deficit and worries that Asian central banks may slow purchases of U.S.
assets. U.S. dollar weakness helped support metal and energy prices, a sector in
which the Fund experienced modest gains. The strength in the U.S. dollar could
also be attributed to a contrasting economic picture between the U.S. and
Europe, highlighted by dovish European Central Bank comments. Energy gains could
also be attributed to continuing cold weather and the possibility that OPEC
would cut production in March. Modest losses were recorded in crops largely due
to a short-covering rally in soybeans sparked by concern that drought will
damage crops in South America. Solid profits were recorded in bonds and interest
rates sectors against small losses in currencies, as strong U.S. inflation and
hawkish comments from the U.S. Federal Reserve sent rates and the U.S. dollar
higher. Modest profits were recorded in energies as crude prices remained
positive for the month despite strong U.S. inventory data. Equity returns were
mixed despite U.S. stocks reaching their lowest level in two months as higher
oil prices weighed on indexes.

April 1, 2005 to June 30, 2005

The Fund posted a gain for the second quarter of 2005. The strongest performing
sectors were interest rates and currency. The energy, agricultural and metals
sectors posted losses for the Fund.

The biggest gain for the quarter was posted in the interest rate sector. Profits
were recorded in bonds against losses in stocks as a raft of weak U.S. economic
data and disappointing earnings reports sent world equities lower. The sell off
in stocks sparked a flight to quality into bonds and a short covering rally in
interest rates; producing the flattest U.S. Treasury yield curve in four years.
Mid-quarter, solid gains were once again recorded in equities and bonds.
Financial futures moved higher as solid U.S. employment and retail sales data
confirmed continued growth in the U.S. while stable inflation data and lower oil
prices soothed concerns about the pace of Fed rate hikes ahead. Following a
stellar May, bonds posted a small increase after a volatile month in June.
Profits came from trading in the Euro, balanced by losses in treasuries, and in
particular short end Eurodollars, as sustained Federal Reserve tightening proved
more likely by the day.

A strong gain was posted for the currency sector. At the beginning of the
quarter, currency returns were mixed as the U.S. dollar remained in a tight
range. The currency returns continued to be mixed during the quarter as the U.S.
dollar regained some of the ground it lost earlier in the year as strong U.S.
economic data and France's rejection of the European Union constitution
supported the greenback. The end of the quarter saw strong gains posted in
currencies and equities, as the strength of the U.S. economy was once again the
main driver behind financial markets. The strength of the U.S. dollar, bolstered
by a widening interest rate differential and continuing U.S. economic growth
relative to Europe, proved positive for the Fund with profits coming from short
positions in the Swiss franc and Japanese yen. Elsewhere the Australian dollar
provided solid gains.

The Fund posted a loss for the agricultural sector. The agricultural sector
started the quarter with a loss and managed to rally back to a profit
mid-quarter. Profits spiraled downwards at the end of the quarter, resulting in
a loss posted for the quarter as a whole.

A loss was posted for the quarter in the metals sector also. The metals sector
performed poorly throughout the entire quarter, posting consistent losses each
month.

The energy sector was the poorest performing sector for the fund with a loss
posted for the quarter. Commodity returns were negative with the largest loss
recorded in energies as crude prices sharply reversed gains made early in April
as weak U.S. economic data coincided with climbing inventories. Commodity
returns were modestly lower, mid-quarter, with energies posting the largest loss
as oil prices slumped to three month lows on the back of rising inventory data.
Energies continued to endure a tough time, with crude oil and natural gas
rallying strongly in the first half of June, before retracing sharply and
generating losses as profit takers entered the market.
