(Unaudited)

The unaudited financial statements contained herein include, in
the opinion of management, all adjustments necessary for a fair
presentation of the results of operations and financial condition
of Dean Witter Diversified Futures Fund Limited Partnership (the
?Partnership?). The financial statements and condensed notes
herein should be read in conjunction with the Partnership?s
December 31, 2002 Annual Report on Form 10-K.

1. Organization
Dean Witter Diversified Futures Fund Limited Partnership is a
Delaware limited partnership organized to engage primarily in the
speculative trading of futures contracts and forward contracts on
physical commodities and other commodity interests, including
foreign currencies, financial instruments, metals, energy products
and agriculturals (collectively, ?futures interests?).

The Partnership?s general partner is Demeter Management
Corporation (?Demeter?). The non-clearing commodity broker is
Morgan Stanley DW Inc. (?Morgan Stanley DW?). The clearing
commodity brokers are Morgan Stanley & Co. Incorporated (?MS &
Co.?) and Morgan Stanley & Co. International Limited (?MSIL?).
The trading manager is Morgan Stanley Futures & Currency
Management Inc. (?MSFCM? or the ?Trading Manager?). Demeter,
DEAN WITTER DIVERSIFIED FUTURES FUND LIMITED PARTNERSHIP
NOTES TO FINANCIAL STATEMENTS (CONTINUED)

Morgan Stanley DW, MS & Co., MSIL and MSFCM are wholly-owned
subsidiaries of Morgan Stanley.

2. Related Party Transactions
The Partnership?s cash is on deposit with Morgan Stanley DW, MS &
Co. and MSIL in futures and forwards trading accounts to meet
margin requirements as needed. Morgan Stanley DW pays interest on
these funds based on a prevailing rate on U.S. Treasury bills.
The Partnership pays brokerage commissions to Morgan Stanley DW.
Management fees and incentive fees, if any, incurred by the
Partnership are paid to MSFCM.

3. Financial Instruments
The Partnership trades futures contracts and forward contracts on
physical commodities and other commodity interests, including
foreign currencies, financial instruments, metals, energy
products and agriculturals. Futures and forwards represent
contracts for delayed delivery of an instrument at a specified
date and price. Risk arises from changes in the value of these
contracts and the potential inability of counterparties to
perform under the terms of the contracts. There are numerous
factors which may significantly influence the market value of
these contracts, including interest rate volatility.

DEAN WITTER DIVERSIFIED FUTURES FUND LIMITED PARTNERSHIP
NOTES TO FINANCIAL STATEMENTS (CONTINUED)

The market value of contracts is based on closing prices quoted by
the exchange, bank or clearing firm through which the contracts
are traded.

The Partnership?s contracts are accounted for on a trade-date
basis and marked to market on a daily basis. The Partnership
accounts for its derivative investments in accordance with the
provisions of Statement of Financial Accounting Standard No. 133,
?Accounting for Derivative Instruments and Hedging Activities?
(?SFAS No. 133?). SFAS No. 133 defines a derivative as a
financial instrument or other contract that has all three of the
following characteristics:

1) One or more underlying notional amounts or payment
provisions;
2) Requires no initial net investment or a smaller initial net
investment than would be required relative to changes in
market factors;
3) Terms require or permit net settlement.

Generally derivatives include futures, forward, swaps or options
contracts and other financial instruments with similar
characteristics such as caps, floors and collars.

The Partnership has credit risk associated with counterparty non-
performance. The credit risk associated with the instruments in
which the Partnership is involved is limited to the amounts
reflected in the Partnership?s statements of financial condition.

The Partnership also has credit risk because Morgan Stanley DW, MS
& Co., and MSIL act as the futures commission merchants or the
counterparties, with respect to most of the Partnership?s assets.
Exchange-traded futures contracts are marked to market on a daily
basis, with variations in value settled on a daily basis. Morgan
Stanley DW, MS & Co. and MSIL, each as a futures commission
merchant for the Partnership?s exchange-traded futures contracts,
are required, pursuant to regulations of the Commodity Futures
DEAN WITTER DIVERSIFIED FUTURES FUND LIMITED PARTNERSHIP
NOTES TO FINANCIAL STATEMENTS (CONCLUDED)

Trading Commission (?CFTC?), to segregate from their own assets,
and for the sole benefit of their commodity customers, all funds
held by them with respect to exchange-traded futures contracts,
including an amount equal to the net unrealized gains (losses) on
all open futures contracts, which funds, in the aggregate, totaled
$101,052,889 and $83,636,660 at March 31, 2003 and December 31,
2002, respectively. With respect to the Partnership?s off-
exchange-traded forward currency contracts, there are no daily
settlements of variations in value nor is there any requirement
that an amount equal to the net unrealized gains (losses) on open
forward contracts be segregated. With respect to those off-
exchange-traded forward currency contracts, the Partnership is at
risk to the ability of MS & Co., the sole counterparty on all of
such contracts, to perform. The Partnership has a netting
agreement with MS & Co. This agreement, which seeks to reduce
both the Partnership?s and MS & Co.?s exposure on off-exchange-
traded forward currency contracts, should materially decrease the
Partnership?s credit risk in the event of MS & Co.?s bankruptcy or
insolvency.

Item 2. MANAGEMENT?S DISCUSSION AND ANALYSIS OF FINANCIAL
CONDITION AND RESULTS OF OPERATIONS

Liquidity. The Partnership deposits its assets with Morgan
Stanley DW as non-clearing broker and MS & Co. and MSIL as
clearing brokers in separate futures and forwards trading accounts
established for the Trading Manager, which assets are used as
margin to engage in trading. The assets are held in either non-
interest bearing bank accounts or in securities and instruments
permitted by the CFTC for investment of customer segregated or
secured funds. The Partnership?s assets held by the commodity
brokers may be used as margin solely for the Partnership?s
trading. Since the Partnership?s sole purpose is to trade in
futures and forwards, it is expected that the Partnership will
continue to own such liquid assets for margin purposes.

The Partnership?s investment in futures and forwards may, from
time to time, be illiquid. Most U.S. futures exchanges limit
fluctuations in prices during a single day by regulations referred
to as ?daily price fluctuations limits? or ?daily limits?. Trades
may not be executed at prices beyond the daily limit. If the
price for a particular futures contract has increased or decreased
by an amount equal to the daily limit, positions in that futures
contract can neither be taken nor liquidated unless traders are
willing to effect trades at or within the limit. Futures prices
have occasionally moved the daily limit for several consecutive
days with little or no trading. These market conditions could
prevent the Partnership from promptly liquidating its
futures contracts and result in restrictions on redemptions.

There is no limitation on daily price moves in trading forward
contracts on foreign currencies. The markets for some world
currencies have low trading volume and are illiquid, which may
prevent the Partnership from trading in potentially profitable
markets or prevent the Partnership from promptly liquidating
unfavorable positions in such markets, subjecting it to
substantial losses. Either of these market conditions could
result in restrictions on redemptions.

The Partnership has never had illiquidity affect a material
portion of its assets. Furthermore, there are no material
trends, demands, commitments, events or uncertainties known at the
present time that will result in, or that are reasonably likely to
result in, the Partnership?s liquidity increasing or decreasing in
any material way.

Capital Resources. The Partnership does not have, nor expect to
have, any capital assets. Redemptions of additional units of
limited partnership interest (?Unit(s)?) in the future will affect
the amount of funds available for investment in futures and
forwards in subsequent periods. It is not possible to estimate
the amount, and therefore, the impact of future redemptions of
Units.

There are no known material trends, favorable or
unfavorable, that would affect, nor any expected material changes
to, the Partnership?s capital resource arrangements at the present
time. The Partnership has no off-balance sheet arrangements, nor
contractual obligations or commercial commitments to make future
payments that would affect the Partnership?s liquidity or capital
resources. The contracts traded by the Partnership are accounted
for on a trade-date basis and marked to market on a daily basis.
The value of futures contracts is the settlement price on the
exchange on which that futures contract is traded on a particular
day and the value of foreign currency forward contracts is based
on the spot rate as of the close of business, New York City time,
on a given day.

Results of Operations
General. The Partnership?s results depend on the Trading Manager
and the ability of the Trading Manager?s trading programs to take
advantage of price movements or other profit opportunities in the
futures and forwards markets. The following presents a summary
of the Partnership?s operations for the three month periods ended
March 31, 2003 and 2002 and a general discussion of its trading
activities during each period. It is important to note, however,
that the Trading Manager trades in various markets at different
times and that prior activity in a particular market does not
mean that such market will be actively traded by the Trading
Manager or will be profitable in the future. Consequently, the
results of operations of the Partnership are difficult to discuss
other than in the context of the Trading Manager?s trading
activities on behalf of the Partnership and how the Partnership
has performed in the past.

The Partnership?s results of operations set forth in the financial
statements on pages 2 through 10 of this report were prepared in
accordance with accounting principles generally accepted in the
United States of America, which require the use of certain
accounting policies that affect the amounts reported in these
financial statements, including the following: The contracts the
Partnership trades are accounted for on a trade-date basis and
marked to market on a daily basis. The difference between their
cost and market value is recorded on the Statements of Operations
as ?Net change in unrealized profit/loss? for open (unrealized)
contracts, and recorded as ?Realized profit/loss? when open
positions are closed out, and the sum of these amounts constitutes
the Partnership?s trading revenues. Interest income revenue, as
well as management fees, incentive fees and brokerage commission
expenses of the Partnership are recorded on an accrual basis.

Demeter believes that, based on the nature of the operations of
the Partnership, no assumptions relating to the application of
critical accounting policies other than those presently used could
reasonably affect reported amounts.

For the Quarter Ended March 31, 2003
For the quarter ended March 31, 2003, the Partnership recorded
total trading revenues, including interest income, of $14,581,732
and posted an increase in net asset value per Unit. The most
significant gains of approximately 8.8% were recorded in the
energy markets, primarily during January and February, from long
positions in natural gas futures as prices trended higher in
response to prolonged frigid temperatures in the northeastern and
midwestern United States. Additional gains were recorded from
long positions in crude oil futures as prices increased amid the
looming threat of military action against Iraq and an overall
decline in inventories. Gains of approximately 4.6% were
recorded in the currency markets, primarily during January and
February, from long positions in the euro versus the British
pound, as the pound?s value declined due to weak economic data
out of the U.K. and an interest rate cut by the Bank of England.
Additional gains stemmed from long positions in the Australian
dollar and South African rand versus the U.S. dollar as the value
of these currencies increased on the heels of higher commodity
prices. Gains of approximately 2.5% were recorded in the global
interest rate markets from long positions in Japanese and German
interest rate futures as prices trended higher amid continued
uncertainty in the global equity markets and ongoing demand from
investors seeking the ?safe haven? of fixed income investments.
A portion of the Partnership?s gains was offset by losses of
approximately 1.0% in the agricultural markets from long
positions in soybean futures as prices reversed in January amid
news of increased supply. Elsewhere in the agricultural
markets, losses were recorded from short positions in coffee
futures as prices reversed higher in early January amid a
decrease in Colombian exports. Total expenses for the three
months ended March 31, 2003 were $3,377,677, resulting in net
income of $11,204,055. The net asset value of a Unit increased
from $1,528.82 at December 31, 2002 to $1,715.93 at March 31,
2003.

For the Quarter Ended March 31, 2002
For the quarter ended March 31, 2002, the Partnership recorded
total trading revenues, including interest income, of $2,026,816
and posted an increase in net asset value per Unit. The most
significant gains of approximately 9.4% were recorded in the
energy markets primarily during March from previously established
long positions in crude oil futures as prices continued trending
higher amid escalating tensions in the Middle East and
supply/demand factors. Additional gains were recorded during
January from previously established short natural gas futures
positions as prices declined following a higher-than-expected
American Gas Association inventory report and forecasts of mild
weather for the Eastern U.S. A portion of the Partnership?s
overall gains was partially offset by losses of approximately 7.9%
recorded in the currency markets primarily during March from
positions in the euro versus the U.S. dollar and British pound
from short-term, choppy price movement. Additional losses were
experienced during early March from previously established short
positions in the Japanese yen as its value reversed higher
versus U.S. dollar amid a repatriation of assets form the U.S. to
Japan. As a result of this strengthening, new long Japanese yen
positions were established only to result in additional losses
later in March as the value of the yen reversed lower on
expectations that the repatriation flows ahead of the Japanese
fiscal year-end would be ending. In the metals markets, losses of
approximately 0.5% were incurred primarily during January from
gold futures positions as prices moved in an erratic manner on
conflicting supply concerns and on the economic outlook. Total
expenses for the three months ended March 31, 2002 were
$1,603,941, resulting in net income of $422,875. The net asset
value of a Unit increased from $1,190.47 at December 31, 2001 to
$1,196.80 March 31, 2002.
Item 3.QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT
MARKET RISK

Introduction
The Partnership is a commodity pool engaged primarily in the
speculative trading of futures and forwards. The market-
sensitive instruments held by the Partnership are acquired for
speculative trading purposes only and, as a result, all or
substantially all of the Partnership?s assets are at risk of
trading loss. Unlike an operating company, the risk of market-
sensitive instruments is central, not incidental, to the
Partnership?s main business activities.

The futures and forwards traded by the Partnership involve
varying degrees of related market risk. Market risk is often
dependent upon changes in the level or volatility of interest
rates, exchange rates, and prices of financial instruments and
commodities. Fluctuations in market risk based upon these
factors result in frequent changes in the fair value of the
Partnership?s open positions, and consequently, in its earnings
and cash flow.

The Partnership?s total market risk is influenced by a wide
variety of factors, including the diversification among the
Partnership?s open positions, the volatility present within the
markets, and the liquidity of the markets. At different times,
each of these factors may act to increase or decrease the market
risk associated with the Partnership.
The Partnership?s past performance is not necessarily
indicative of its future results. Any attempt to numerically
quantify the Partnership?s market risk is limited by the
uncertainty of its speculative trading. The Partnership?s
speculative trading may cause future losses and volatility (i.e.,
?risk of ruin?) that far exceed the Partnership?s experience to
date or any reasonable expectations based upon historical changes
in market value.

Quantifying the Partnership?s Trading Value at Risk
The following quantitative disclosures regarding the Partnership?s
market risk exposures contain ?forward-looking statements? within
the meaning of the safe harbor from civil liability provided for
such statements by the Private Securities Litigation Reform Act of
1995 (set forth in Section 27A of the Securities Act of 1933 and
Section 21E of the Securities Exchange Act of 1934). All
quantitative disclosures in this section are deemed to be forward-
looking statements for purposes of the safe harbor, except for
statements of historical fact.

The Partnership accounts for open positions on the basis of mark-
to-market accounting principles. Any loss in the market value of
the Partnership?s open positions is directly reflected in the
Partnership?s earnings, whether realized or unrealized, and its
cash flow. Profits and losses on open positions of exchange-
traded futures and forwards are settled daily through variation
margin.
The Partnership?s risk exposure in the market sectors
traded by the Trading Manager is estimated below in terms of Value
at Risk (?VaR?). The VaR model used by the Partnership includes
many variables that could change the market value of the
Partnership?s trading portfolio. The Partnership estimates VaR
using a model based upon historical simulation with a confidence
level of 99%. Historical simulation involves constructing a
distribution of hypothetical daily changes in the value of a
trading portfolio. The VaR model takes into account linear
exposures to price and interest rate risk. Market risks that are
incorporated in the VaR model include equity and commodity prices,
interest rates, foreign exchange rates, and correlation among
these variables. The hypothetical changes in portfolio value are
based on daily percentage changes observed in key market indices
or other market factors (?market risk factors?) to which the
portfolio is sensitive. The historical observation period of the
Partnership?s VaR is approximately four years. The one-day 99%
confidence level of the Partnership?s VaR corresponds to the
negative change in portfolio value that, based on observed market
risk factors, would have been exceeded once in 100 trading days.
In other words, one-day VaR for a portfolio is a number such that
losses in this portfolio are estimated to exceed the VaR only one
day in 100. VaR typically does not represent the worst-case
outcome.

VaR is calculated using historical simulation. Demeter uses
approximately four years of daily market data (1,000 observations)
and revalues its portfolio (using delta-gamma
approximations) for each of the historical market moves that
occurred over this time period. This generates a probability
distribution of daily ?simulated profit and loss? outcomes. The
VaR is the appropriate percentile of this distribution. For
example, the 99% one-day VaR would represent the 10th worst outcome
from Demeter?s simulated profit and loss series.

The Patnership?s VaR computations are based on the risk
representation of the underlying benchmark for each instrument or
contract and does not distinguish between exchange and non-
exchange-traded instruments and is also not based on exchange
and/or dealer-based margin requirements.

VaR models, including the Partnership?s, are continuously
evolving as trading portfolios become more diverse and modeling
techniques and systems capabilities improve. Please note that
the VaR model is used to numerically quantify market risk for
historic reporting purposes only and is not utilized by either
Demeter or the Trading Manager in their daily risk management
activities. Please further note that VaR as described above may
not be comparable to similarly titled measures used by other
entities.

The Partnership?s Value at Risk in Different Market Sectors
The following table indicates the VaR associated with the
Partnership?s open positions as a percentage of total net assets
by primary market risk category at March 31, 2003 and
2002. At March 31, 2003 and 2002, the Partnership?s total
capitalization was approximately $98 million and $77 million,
respectively.

Primary Market March 31, 2003 March 31, 2002
Risk Category Value at Risk Value at Risk

Currency (1.57)% (2.61)%
Interest Rate (1.39) (1.96)
Equity - (0.08)
Commodity (1.76) (2.28)
Aggregate Value at Risk (2.88)% (4.01)%

The VaR for a market category represents the one-day downside risk
for the aggregate exposures associated with this market category.
The Aggregate Value at Risk above represents the VaR of the
Partnership?s open positions across all the market categories, and
is less than the sum of the VaRs for all such market categories
due to the diversification benefit across asset classes.

The table above represents the VaR of the Partnership?s open
positions at March 31, 2003 and 2002 only and is not necessarily
representative of either the historic or future risk of an
investment in the Partnership. Because the Partnership?s only
business is the speculative trading of futures and forwards, the
composition of its trading portfolio can change significantly over
any given time period, or even within a single trading day. Any
changes in open positions could positively or negatively
materially impact market risk as measured by VaR.

The table below supplements the quarter-end VaR by presenting the
Partnership?s high, low and average VaR, as a percentage of total
net assets for the four quarterly reporting periods from
April 1, 2002 through March 31, 2003.

Primary Market Risk Category High Low Average
Currency (3.42)% (1.57)% (2.50)%

Interest Rate (3.02) (1.16) (2.02)

Equity (0.16) - (0.05)

Commodity (2.48) (0.97) (1.87)

Aggregate Value at Risk (4.78)% (2.88)% (3.83)%

Limitations on Value at Risk as an Assessment of Market Risk
The face value of the market sector instruments held by the
Partnership is typically many times the applicable margin
requirements. Margin requirements generally range between 2% and
15% of contract face value. Additionally, the use of leverage
causes the face value of the market sector instruments held by the
Partnership to typically be many times the total capitalization of
the Partnership. The value of the Partnership?s open positions
thus creates a ?risk of ruin? not typically found in other
investments. The relative size of the positions held may cause
the Partnership to incur losses greatly in excess of VaR within a
short period of time, given the effects of the leverage employed
and market volatility. The VaR tables above, as well as
the past performance of the Partnership, give no indication of
such ?risk of ruin?. In addition, VaR risk measures should be
viewed in light of the methodology?s limitations, which include
the following:
* past changes in market risk factors will not always result in
accurate predictions of the distributions and correlations of
future market movements;
* changes in portfolio value caused by market movements may
differ from those of the VaR model;
* VaR results reflect past trading positions while future risk
depends on future positions;
* VaR using a one-day time horizon does not fully capture the
market risk of positions that cannot be liquidated or hedged
within one day; and
* the historical market risk factor data used for VaR estimation
may provide only limited insight into losses that could be
incurred under certain unusual market movements.

The VaR tables above present the results of the Partnership?s VaR
for each of the Partnership?s market risk exposures and on an
aggregate basis at March 31, 2003 and 2002, and for the end of the
four quarterly reporting periods from April 1, 2002 through March
31, 2003. Since VaR is based on historical data, VaR should not
be viewed as predictive of the Partnership?s future financial
performance or its ability to manage or monitor risk. There can
be no assurance that the Partnership?s actual losses on a
particular day will not exceed the VaR amounts indicated above or
that such losses will not occur more than once in 100 trading
days.

Non-Trading Risk
The Partnership has non-trading market risk on its foreign cash
balances not needed for margin. These balances and any market
risk they may represent are immaterial.

At March 31, 2003, the Partnership?s cash balance at Morgan
Stanley DW was approximately 100% of its total net asset value.
A decline in short-term interest rates will result in a decline
in the Partnership?s cash management income. This cash flow risk
is not considered to be material.

Materiality, as used throughout this section, is based on an
assessment of reasonably possible market movements and any
associated potential losses, taking into account the leverage,
optionality and multiplier features of the Partnership?s market-
sensitive instruments, in relation to the Partnership?s net
assets.

Qualitative Disclosures Regarding Primary Trading Risk Exposures
The following qualitative disclosures regarding the Partnership?s
market risk exposures - except for (A) those disclosures that are
statements of historical fact and (B) the descriptions of how the
Partnership manages its primary market risk exposures -
constitute forward-looking statements within the meaning of
Section 27A of the Securities Act and Section 21E of the
Securities Exchange Act. The Partnership?s primary market risk
exposures as well as the strategies used and to be used by
Demeter and the Trading Manager for managing such exposures are
subject to numerous uncertainties, contingencies and risks, any
one of which could cause the actual results of the Partnership?s
risk controls to differ materially from the objectives of such
strategies. Government interventions, defaults and expropria-
tions, illiquid markets, the emergence of dominant fundamental
factors, political upheavals, changes in historical price
relationships, an influx of new market participants, increased
regulation and many other factors could result in material losses
as well as in material changes to the risk exposures and the risk
management strategies of the Partnership. Investors must be
prepared to lose all or substantially all of their investment in
the Partnership.

The following were the primary trading risk exposures of the
Partnership at March 31, 2003, by market sector. It may be
anticipated, however, that these market exposures will vary
materially over time.

Currency. The primary market exposure of the Partnership at
March 31, 2003 was to the currency sector. The Partnership?s
currency exposure is to exchange rate fluctuations, primarily
fluctuations which disrupt the historical pricing
relationships between different currencies and currency pairs.
Interest rate changes as well as political and general economic
conditions influence these fluctuations. The Partnership trades
a large number of currencies, including cross-rates - i.e.,
positions between two currencies other than the U.S. dollar. At
March 31, 2003, the Partnership?s major exposures were to the
euro currency crosses and outright U.S. dollar positions.
Outright positions consist of the U.S. dollar vs. other
currencies. These other currencies include major and minor
currencies. Demeter does not anticipate that the risk profile of
the Partnership?s currency sector will change significantly in
the future. The currency trading VaR figure includes foreign
margin amounts converted into U.S. dollars with an incremental
adjustment to reflect the exchange rate risk inherent to the
U.S.-based Partnership in expressing VaR in a functional currency
other than U.S. dollars.

Interest Rate. The second largest exposure at March 31, 2003 was
to the global interest rate sector. Exposure was primarily
spread across the Japanese, Australian and U.S. interest rate
sectors. Interest rate movements directly affect the price of the
sovereign bond futures positions held by the Partnership and
indirectly affect the value of its stock index and currency
positions. Interest rate movements in one country, as well as
relative interest rate movements between countries, materially
impact the Partnership?s profitability. The Partnership?s
primary interest rate exposure is generally to interest
rate fluctuations in the U.S. and the other G-7 countries. The
G-7 countries consist of France, the U.S., Britain, Germany,
Japan, Italy and Canada. However, the Partnership also takes
futures positions in the government debt of smaller nations -
e.g., Australia. Demeter anticipates that G-7 countries and
Australian interest rates will remain the primary interest rate
exposure of the Partnership for the foreseeable future. The
speculative futures positions held by the Partnership may range
from short to long-term instruments. Consequently, changes in
short, medium or long-term interest rates may have an effect on
the Partnership.

Commodity.
Metals. The Partnership's metals exposure at March 31, 2003
was to fluctuations in the price of precious metals such as
gold, and base metals, such as aluminum, copper, nickel and
zinc. Economic forces, supply and demand inequalities,
geopolitical factors and market expectations influence price
movements in these markets. The Trading Manager, from time
to time, takes positions as market opportunities develop and
Demeter anticipates that the Partnership will continue to do
so.

Energy. At March 31, 2003, the Partnership?s energy exposure
was primarily to futures contracts in crude oil. Price
movements in this market result from political developments
in the Middle East, weather patterns and other
economic fundamentals. Significant profits and losses,
which have been experienced in the past, are expected to
continue to be experienced in the future.

Soft Commodities and Agriculturals. At March 31, 2003, the
Partnership had exposure to the markets that comprise these
sectors. Most of the exposure was to the coffee, corn and
cocoa markets. Supply and demand inequalities, severe
weather disruption and market expectations affect price
movements in these markets.

Qualitative Disclosures Regarding Non-Trading Risk Exposure
The following was the only non-trading risk exposure of the
Partnership at March 31, 2003:

Foreign Currency Balances. The Partnership?s primary
foreign currency balance at March 31, 2003 was in Australian
dollars. The Partnership controls the non-trading risk of
these balances by regularly converting them back into U.S.
dollars upon liquidation of their respective positions.

Qualitative Disclosures Regarding Means of Managing Risk Exposure
The Partnership and the Trading Manager, separately, attempt to
manage the risk of the Partnership?s open positions in essentially
the same manner in all market categories traded. Demeter attempts
to manage market exposure by diversifying the Partnership?s assets
among different market sectors and trading approaches, and
monitoring the performance of the Trading Manager daily. In
addition, the Trading Manager establishes diversification
guidelines, often set in terms of the maximum margin to be
committed to positions in any one market sector or market-
sensitive instrument.

Demeter monitors and controls the risk of the Partnership?s non-
trading instrument, cash. Cash is the only Partnership investment
directed by Demeter, rather than the Trading Manager.

Item 4. CONTROLS AND PROCEDURES
(a) As of a date within 90 days of the filing date of this
quarterly report, the President and Chief Financial
Officer of the general partner, Demeter, have evaluated
the effectiveness of the Partnership?s disclosure
controls and procedures (as defined in Rules 13a-14 and
15d-14 of the Exchange Act), and have judged such
controls and procedures to be effective.

(b) There have been no significant changes in the
Partnership?s internal controls or in other factors that
could significantly affect these controls subsequent to
the date of their evaluation.
