(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 Global Perspective Portfolio L.P. (the
"Partnership"). The financial statements and condensed notes
herein should be read in conjunction with the Partnership's
December 31, 2001 Annual Report on Form 10-K.

1. Organization
Dean Witter Global Perspective Portfolio 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.

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., Inc. ("MS & Co.") and
Morgan Stanley & Co. International Limited ("MSIL"). Demeter,
Morgan Stanley DW, MS & Co. and MSIL are wholly-owned subsidiaries
of Morgan Stanley. The trading advisors for the Partnership are

DEAN WITTER GLOBAL PERSPECTIVE PORTFOLIO L.P.
NOTES TO FINANCIAL STATEMENTS (CONTINUED)

EMC Capital Management, Inc. and Millburn Ridgefield Corporation
(collectively, the "Trading Advisors").

On February 27, 2002, the Partnership received notification of a
preliminary entitlement to payment from the Sumitomo Copper
Litigation Settlement Administrator. The Partnership received
payment of this settlement award in the amount of $675,411 as of
August 31, 2002.

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 the average yield on 13-week U.S.
Treasury bill rates. The Partnership pays brokerage commissions
to Morgan Stanley DW.

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

DEAN WITTER GLOBAL PERSPECTIVE PORTFOLIO L.P.
NOTES TO FINANCIAL STATEMENTS (CONTINUED)

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
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.

DEAN WITTER GLOBAL PERSPECTIVE PORTFOLIO L.P.
NOTES TO FINANCIAL STATEMENTS (CONTINUED)

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:

Net Unrealized Gains (Losses)
on Open Contracts Longest Maturities

Dec. 31, 2001 111,366 268,883 380,249 Jun. 2002 Mar. 2002

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

DEAN WITTER GLOBAL PERSPECTIVE PORTFOLIO L.P.
NOTES TO FINANCIAL STATEMENTS (CONTINUED)

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 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 $11,944,392 and
$10,085,692 at September 30, 2002 and December 31, 2001,
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

DEAN WITTER GLOBAL PERSPECTIVE PORTFOLIO L.P.
NOTES TO FINANCIAL STATEMENTS (CONCLUDED)

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 each 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 contracts has increased
or decreased by an amount equal to the daily limit, positions in
that futures or options contracts 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.

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.

The Partnership has never had illiquidity affect a material
portion of its assets.

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, 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, 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 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 Advisors
and the ability of the Trading Advisors' 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 and nine
month periods ended September 30, 2002 and 2001 and a general
discussion of its trading activities during each period. It is
important to note, however, that the Trading Advisors trade 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 Advisors 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
Advisors' trading activities on behalf of the Partnership and how
the Partnership has performed in the past.

The Partnership's results of operations are set forth in
financial statements prepared in accordance with United States
generally accepted accounting principles, 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. Earned interest

income revenue, as well as management fees, incentive fees and
brokerage 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 other than those presently used
relating to the application of critical accounting policies are
reasonably plausible that could affect reported amounts.

For the Quarter and Nine Months Ended September 30, 2002
For the quarter ended September 30, 2002, the Partnership recorded
total trading revenues, including interest income, of $2,204,722
and posted an increase in net asset value per Unit. The most
significant gains of approximately 12.4% were recorded in the
global interest rate futures markets from previously established
long positions in U.S. and European interest rate futures, as
prices trended higher, due to investors seeking a safe haven from
falling equity prices and increased pessimism regarding a global
economic recovery. Additional gains of approximately 5.1% were
recorded in the global stock index futures markets, primarily
during July and August, from short positions in Pacific Rim,
European, and U.S. stock index futures as prices weakened amid
suspicions regarding corporate accounting practices and global
political and economic uncertainty. A portion of the
Partnership's overall gains was offset by losses of approximately
3.6% in the currency markets from long positions in the Japanese

yen and euro relative to the U.S. dollar as these currencies
weakened against the dollar due to the emphasis on a strong dollar
policy by the Bush Administration during July and the persistence
of trendless price activity during August and September. In the
metals markets, losses of approximately 1.4% were recorded from
positions in zinc and silver futures as prices in both markets
moved erratically. Smaller losses of approximately 1.3% were
recorded in the agricultural markets from long positions in cotton
and coffee futures as prices reversed lower amid supply and demand
concerns. On February 27, 2002, the Partnership received
notification of a preliminary entitlement to payment from the
Sumitomo Copper Litigation Settlement Administrator. The
Partnership received payment of this settlement award in the
amount of $675,411 as of August 31, 2002. Total expenses for the
three months ended September 30, 2002 were $280,950, resulting in
net income of $1,923,772. The net asset value of a Unit increased
from $1,064.04 at June 30, 2002 to $1,265.29 at September 30,
2002.

For the nine months ended September 30, 2002, the Partnership
recorded total trading revenues, including interest income, of
$3,424,655 and posted an increase in net asset value per Unit.
The most significant gains of approximately 9.2% were recorded in
the currency markets, primarily during May and June, from
previously established long positions in the euro, Japanese yen,
and Swiss franc relative to the U.S. dollar as the value of these

currencies strengthened against the dollar amid falling U.S.
equity prices and increased tensions in the Israeli-Palestinian
conflict. Gains of approximately 9.1% were recorded from long
positions in the global interest rate futures markets as prices
trended higher during a majority of the second and third quarters
due to uncertainty regarding a global economic recovery.
Additional gains of approximately 5.4% were recorded in the global
stock index futures markets from short positions in European and
U.S. stock index futures as prices continued to trend lower due to
suspicions regarding corporate accounting practices and weak
economic data. A portion of the Partnership's overall gains was
offset by losses of approximately 5.0% in the agricultural markets
primarily from positions in sugar and coffee futures as prices
moved without consistent direction amid supply and demand
concerns. Smaller losses of approximately 2.1% were recorded in
the metals markets from positions in aluminum, copper, and zinc
futures as trendless price activity persisted throughout the
period. Total expenses for the nine months ended September 30,
2002 were $797,516, resulting in net income of $2,627,139. The
net asset value of a Unit increased from $990.95 at December 31,
2001 to $1,265.29 at September 30, 2002.

For the Quarter and Nine Months Ended September 30, 2001
For the quarter ended September 30, 2001, the Partnership recorded
total trading revenues, including interest income, of $882,435 and

posted an increase in net asset value per Unit. The most
significant gains of approximately 11.6% were recorded throughout
a majority of the quarter in the global stock index futures
markets from short positions in DAX, Hang Seng and Nikkei Index
futures as equity prices decreased on corporate profit warnings
and amid worries regarding global economic uncertainty. In the
metals markets, gains of approximately 2.1% were recorded
primarily during July from short positions in aluminum, zinc,
nickel and copper futures as base metal prices declined on waning
demand prompted by weak U.S. economic data. These gains were
partially offset by losses of approximately 5.7% experienced in
the energy markets primarily during August from short positions in
crude oil and unleaded gas futures as prices rose as a result of
declining inventories and growing tensions in the Middle East.
Additional losses in these same markets were recorded during
September from long futures positions as oil prices reversed lower
due to near-term concerns over the effects of a global economic
slowdown on oil demand. Smaller losses of approximately 4.6% were
recorded in the currency markets primarily during September from
cross-rate transactions involving the euro relative to the British
pound. During August, additional currency losses were experienced
from short positions in the Japanese yen as the value of the yen
strengthened versus the U.S. dollar due to Japanese repatriation
of assets and the weakness in the U.S. resulting from economic
pessimism. Long Japanese yen positions experienced additional

losses during September as the value of the yen reversed lower and
the U.S. dollar strengthened amid optimistic economic data and the
Bank of Japan's surprising interventions. Total expenses for the
three months ended September 30, 2001 were $360,781, resulting in
net income of $521,654. The net asset value of a Unit increased
from $1,036.09 at June 30, 2001 to $1,084.38 at September 30,
2001.

For the nine months ended September 30, 2001, the Partnership
recorded total trading revenues, including interest income, of
$1,923,750 and posted an increase in net asset value per Unit.
The most significant gains of approximately 14.7% were recorded in
the global stock index futures markets primarily during February
and March and throughout a majority of the third quarter from
short positions in DAX, Hang Seng and Nikkei Index futures as
equity prices declined on weakness in high technology issues and
fears regarding global economics uncertainty. These gains were
partially offset by losses of approximately 7.7% recorded in the
energy markets during the first three quarters from positions in
crude oil futures and its related products as a result of
volatility in oil prices due to a continually changing outlook for
supply, production and global demand. In the global interest rate
futures markets, losses of approximately 2.2% were experienced
primarily during April from long positions in European interest
rate futures as prices reversed sharply lower, after trending

higher earlier in the year, as investors deserted fixed income
securities in an asset shift to equities. Smaller losses of
approximately 1.7% were recorded primarily during April in the
soft commodities markets from short sugar futures positions as
prices increased on technical factors. Total expenses for the
nine months ended September 30, 2001 were $1,040,273, resulting in
net income of $883,477. The net asset value of a Unit increased
from $1,005.36 at December 31, 2000 to $1,084.38 at September 30,
2001.

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 Advisors 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
for a portfolio are estimated to exceed the VaR only one day in
100.

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.

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 Advisors 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 September 30, 2002 and 2001.

At both September 30, 2002 and 2001, the Partnership's total
capitalization was approximately $12 million.

Primary Market September 30, 2002 September 30, 2001
Risk Category Value at Risk Value at Risk

Interest Rate (1.54)% (1.14)%
Equity (1.09) (0.95)
Currency (1.02) (0.93)
Commodity (1.69) (0.73)
Aggregate Value at Risk (2.85)% (2.02)%

The VaR for a market category represents the one-day downside
risk for the aggregate exposures associated with this market
category. The aggregate VaR, listed above for the Partnership,
represents the aggregate 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 September 30, 2002 and 2001 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
October 1, 2001 through September 30, 2002.

Primary Market Risk Category High Low Average
Interest Rate (2.38)% (0.99)% (1.70)%
Equity (1.87) (0.33) (1.04)
Currency (2.04) (0.60) (1.39)
Commodity (1.72) (0.55) (1.21)
Aggregate Value at Risk (3.56)% (2.34)% (2.92)%

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 exposure and on an
aggregate basis at September 30, 2002 and 2001, and for the end of
the four quarterly reporting periods from October 1, 2001 through
September 30, 2002. 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 September 30, 2002, the Partnership's cash balance at Morgan
Stanley DW was approximately 84% 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 Advisors
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 September 30, 2002, by market sector. It may be
anticipated, however, that these market exposures will vary
materially over time.

Interest Rate. The primary market exposure of the Partnership
at September 30, 2002 was to the global interest rate sector.
Exposure was primarily spread across the European, U.S. 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. However, the
Partnership also takes futures positions in the government debt
of smaller nations - e.g., Australia. Demeter anticipates that
G-7 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 equity market exposure at September
30, 2002 was to the global stock index sector, primarily 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 September 30, 2002, the Partnership's primary
exposures were to the Hang Seng (Hong Kong), NASDAQ (U.S.) and
S&P 500 (U.S.) stock indices. The Partnership was exposed to the
risk of adverse price trends or static markets in these 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.

Currency. The Partnership's currency exposure at September 30,
2002 was 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 September 30, 2002,
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.

Commodity.
Energy. At September 30, 2002, the Partnership's energy
exposure was shared primarily by 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 these markets. Natural gas
has exhibited volatility in prices resulting from weather
patterns and supply and demand factors and may continue in
this choppy pattern.

Metals. The Partnership's metals exposure at September 30,
2002 was to fluctuations in the price of precious metals,
such as gold, and base metals, such as aluminum, zinc,
copper and nickel. Economic forces, supply and demand

inequalities, geopolitical factors and market expectations
influence price movements in these markets. The Trading
Advisors have, from time to time, taken positions as market
opportunities develop. Demeter anticipates that the
Partnership will continue to be exposed to the precious and
base metals markets.

Soft Commodities and Agriculturals. At September 30, 2002,
the Partnership had exposure to the markets that comprise
these sectors. Most of the exposure was in sugar, cotton
and soybeans and its related products. 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 September 30, 2002:

Foreign Currency Balances. The Partnership's primary
foreign currency balances at September 30, 2002 were in
euros, Hong Kong dollars and British pounds. 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 Advisors, 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 Trading Advisors, each of
whose strategies focus on different market sectors and trading
approaches, and monitoring the performance of the Trading
Advisors daily. In addition, the Trading Advisors establish
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 Advisors.

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 Partnership's disclosure controls and procedures,
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.
