(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 Morgan Stanley Charter Millburn L.P. (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
Morgan Stanley Charter Millburn L.P. is a Delaware limited
partnership organized to engage primarily in the speculative
trading of futures contracts, options on futures contracts and
forward contracts on physical commodities and other commodity
interests, including foreign currencies, financial instruments,
metals, energy and agricultural products. The Partnership is one
of the Morgan Stanley Charter series of funds, comprised of the
Partnership, Morgan Stanley Charter Campbell L.P., Morgan Stanley
Charter Graham L.P., Morgan Stanley Charter Welton L.P. (?Charter
Welton?), and Morgan Stanley Charter MSFCM L.P.

MORGAN STANLEY CHARTER MILLBURN L.P.
NOTES TO FINANCIAL STATEMENTS (CONTINUED)

Charter Welton terminated trading effective December 31, 2002 and
commenced its dissolution in April 2003 pursuant to its Limited
Partnership Agreement.

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?).
Demeter, Morgan Stanley DW, MS & Co. and MSIL are wholly-owned
subsidiaries of Morgan Stanley. Millburn Ridgefield Corporation
(the ?Trading Advisor?) is the trading advisor to the Partnership.

2. Related Party Transactions
The Partnership's cash is on deposit with Morgan Stanley DW, MS &
Co. and MSIL in futures, forwards and options trading accounts to
meet margin requirements as needed. Morgan Stanley DW pays
interest on these funds based on a rate equal to that earned by
Morgan Stanley DW on its U.S. Treasury bill investments. The
Partnership pays brokerage fees to Morgan Stanley DW.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

3. Financial Instruments
The Partnership trades futures contracts, options on futures
contracts and forward contracts on physical commodities and other

commodity interests, including foreign currencies, financial
instruments, metals, energy and agricultural products. 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.

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
MORGAN STANLEY CHARTER MILLBURN L.P.
NOTES TO FINANCIAL STATEMENTS (CONTINUED)

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 net unrealized gains (losses) on open contracts, reported as a
component of ?Equity in futures interests trading accounts? on the
statements of financial condition, and their longest contract
maturities were as follows:

MORGAN STANLEY CHARTER MILLBURN L.P.
NOTES TO FINANCIAL STATEMENTS (CONTINUED)

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 and futures-styled options contracts are
marked to market on a daily basis, with variations in value
settled on a daily basis. Each of Morgan Stanley DW, MS & Co.,
and MSIL, as a futures commission merchant for the Partnership?s
exchange-traded futures and futures-styled options contracts, are
required, pursuant to regulations of the Commodity Futures
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 and futures-
styled options contracts, including an amount equal to the net
unrealized gains (losses) on all open futures and futures-styled
options contracts, which funds, in the aggregate, totaled
$51,099,599 and $42,946,755 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
MORGAN STANLEY CHARTER MILLBURN L.P.
NOTES TO FINANCIAL STATEMENTS (CONTINUED)

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

MORGAN STANLEY CHARTER MILLBURN L.P.
NOTES TO FINANCIAL STATEMENTS (CONTCLUDED)

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, forwards and options trading accounts
established for the Trading Advisor, 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, forwards and options, it is expected that the Partnership
will continue to own such liquid assets for margin purposes.

The Partnership?s investment in futures, forwards and options 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 or options contract has increased
or decreased by an amount equal to the daily limit, positions in
that futures or options 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 or options
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, exchanges and sales of
additional units of limited partnership interest (?Unit(s)?) in
the future will affect the amount of funds available for
investment in futures, forwards and options 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 Advisor
and the ability of the Trading Advisor?s trading programs to take
advantage of price movements or other profit opportunities in the
futures, forwards and options 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 Advisor 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 Advisor 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
Advisor'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 11 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
fees 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 $952,464
and, after expenses, posted a decrease in net asset value per
Unit. The most significant losses of approximately 3.8% were
recorded in the currency markets, primarily during February and
March, from positions in the Japanese yen versus the U.S. dollar
as the value of the yen moved without consistent direction in
response to changing perceptions regarding the progress of
military action against Iraq and ongoing uncertainty regarding the
Japanese economy. Additional losses of approximately 0.5% were
recorded in the global stock index markets, primarily during
January and February, from positions in Asian stock index futures
from trendless equity prices amid a continued lack of confidence
in the global economy, particularly in the Pacific Rim region. A
portion of the Partnership?s overall losses was offset by gains of
approximately 4.5% recorded in the energy markets, primarily
during February, from long positions in natural gas futures as
prices jumped sharply higher amid prolonged frigid temperatures in
the northeastern and midwestern U.S. Additional gains were
recorded from long futures positions in crude oil and its related
products as prices continued to trend higher amid the
looming threat of military action against Iraq. Gains of
approximately 2.4% were recorded in the global interest rate
markets, primarily during February, from long positions in German
and U.S. interest rate futures as prices moved higher as investors
continued to seek the ?safe haven? of fixed income investments in
response to prolonged uncertainty in global equity markets. Total
expenses for the three months ended March 31, 2003 were
$1,535,952, resulting in a net loss of $583,488. The net asset
value of a Unit decreased from $11.18 at December 31, 2002 to
$11.11 at March 31, 2003.

For the Quarter Ended March 31, 2002
For the quarter ended March 31, 2002, the Partnership recorded
total trading losses, net of interest income, of $79,004 and
posted a decrease in net asset value per Unit. The most
significant losses of approximately 2.6% were recorded in the
currency markets primarily during February and March from
previously established short positions in the Japanese yen
relative to the U.S. dollar. The yen strengthened against the
dollar following asset repatriation from the U.S. to Japan and a
drop in Japan?s unemployment rate. Continued strength in the yen
through mid March encouraged establishing new long positions,
which eventually added to earlier losses when the value of the yen
fell on news that asset repatriation would end with the Japanese
fiscal year. Smaller losses of approximately 1.6% were recorded in
agricultural markets mostly during January from previously
established long positions in sugar futures when prices declined
on news that Brazilian exports would substantially increase
international supply. Additional losses were recorded during
February from subsequently established short positions in sugar
futures as prices finished slightly higher at March?s end after
non-trending movement for several weeks prior. Losses of
approximately 1.5% were recorded in the global stock index markets
mainly during March as equity pries continued non-trending
patterns amidst global economic and military uncertainty.
Partially offsetting gains of approximately 4.9% were recorded in
the energy markets primarily during March from previously
established long positions in crude oil when prices continued
trending higher amid escalating tensions in the Middle East and
supply/demand factors. Total expenses for the three months ended
March 31, 2002 were $680,189, resulting in a net loss of $759,193.
The net asset value of a Unit decreased from $9.23 at December 31,
2001 to $8.99 at 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, forwards and options. 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, forwards and options 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, forwards and options are settled daily
through variation margin.
The Partnership?s risk exposure in the market sectors traded by
the Trading Advisor 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 Partner-
ship?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 Partnership?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 Advisor 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 $49 million and $30 million, respectively.

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

Currency (1.51)% (0.45)%
Interest Rate (0.65) (1.84)
Equity (0.41) (0.61)
Commodity (0.61) (1.99)
Aggregate Value at Risk (1.87)% (2.75)%

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 VaR(s) 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, forwards and
options, 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 (2.59)% (1.51)% (2.18)%

Interest Rate (2.88) (0.65) (1.77)

Equity (1.08) (0.41) (0.70)

Commodity (1.65) (0.61) (0.99)

Aggregate Value at Risk (3.89)% (1.87)% (3.15)%

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 usually 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 94% 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 Advisor
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 expropriations, 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 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 market exposure of the
Partner-ship at March 31, 2003 was to the global interest rate
sector. Exposure was primarily spread across the U.S., European
and Japanese 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. Demeter anticipates
that the G-7 countries 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.

Equity. The Partnership?s primary equity exposure at March 31,
2003 was to price risk in the G-7 countries. The stock index
futures traded by the Partnership are by law limited to futures
on broadly-based indices. At March 31, 2003, the Partnership?s
primary exposures were to the Hang Seng (Hong Kong), NASDAQ
(U.S.) and TOPIX (Japan) stock indices. The Partnership is
primarily exposed to the risk of adverse price trends or
static markets in the Hong Kong, U.S. and Japanese stock indices.
Static markets would not cause major market changes but would
make it difficult for the Partnership to avoid being ?whipsawed?
into numerous small losses.

Commodity.
Energy. At March 31, 2003, the Partnership?s energy
exposure was primarily to futures contracts in crude oil and
its related products, and natural gas. Price movements in
these markets 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. Natural gas has exhibited
volatility in prices resulting from weather patterns and
supply and demand factors and will likely continue in this
choppy pattern.

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 and zinc.
Economic forces, supply and demand inequalities,
geopolitical factors and market expectations influence price
movements in these markets. The Trading Advisor,
from time to time, takes positions when market opportunities
develop and Demeter anticipates that the Partnership will
continue to do so.

Soft Commodities and Agriculturals. At March 31, 2003, the
Partnership had exposure to the corn, cotton and coffee
markets. Supply and demand inequalities, severe weather
disruptions 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 balances at March 31, 2003 were in euros, British
pounds, Japanese yen and Hong Kong 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 Advisor, 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 Advisor daily. In
addition, the Trading Advisor 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 Advisor.

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.
