     In the opinion of management, the financial statements contain all
     adjustments necessary to present fairly the financial position of ML Winton

     its operations for the period February 1, 2005 (commencement of operations)
     to September 30, 2005. However, the operating results for the interim
     period may not be indicative of the results for the period ending December

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.

     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 SEPTEMBER 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 Federal Reserve 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 U.S.
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.

July 1, 2005 to September 30, 2005

The Fund posted a trading loss for the quarter, primarily due to losses in the
interest rate sector. The energy, stock indices, currencies, commissions, and
metals sectors posted gains, while trading in the agricultural commodities and
interest rates posted losses.

The energy sector posted the largest gains for the quarter. Steady returns
mid-quarter driven by the spike in energy prices caused by Hurricane Katrina and
the impact on United States energy production and distribution. As concerns over
supply shortages subsided, a sell off in the energy markets detracted from
performance but not enough to offset gains posted earlier in the quarter.

Trading in stock indices posted gains throughout the quarter for the Fund.
Strong gains early in the quarter in equity markets were caused by a rally as
sentiment and stronger earnings boosted confidence. Trading in the Nikkei and
Hang Seng contributed to performance.

The currency sector posted a gain for the Fund despite losses in the first half
of the quarter. Currencies endured a volatile period. The long awaited decision
by China to take the first steps to reforming its currency markets had a slight
impact on currency positions. The Australian dollar strengthened, attributing to
profits while the Swiss franc was the worst affected market.

A slight gain was also posted for the quarter in the metals sector. The metals
sector had relatively flat performance throughout the entire quarter posting
small gains early on and ending the quarter posting losses.

Trading in agricultural commodities posted a slight loss. The agriculture sector
had relatively flat performance throughout the entire quarter posting losses
throughout with small gains during mid-quarter.

The interest rate sector posted the largest losses for the Fund during the
quarter. Fixed income positions suffered as the markets slid on the back of
comments from Federal Reserve chairman Greenspan on the continued robustness of
the U.S. economy, and the perceived reduction in future demand from China as
they are now free to invest in other currencies and not simply invest in U.S.
treasuries. The after effects of the U.S. hurricane season continued to plague
the markets later in the quarter. The initial feeling that the Federal Reserve
would react to the inevitable impact on the U.S. economy by holding interest
rates steady proved mistaken. As a result, the sell off in the U.S. treasuries
dragged bond markets down across the globe. Short term interest rate futures
came under similar pressure, as the continued high level of oil prices and other
input prices continued to add weight to inflationary fears in the U.S.
