Fund L.P.
Limited
Partners for the year
ended December
31, 2000 II, III and IV


































PART I

Item 1. BUSINESS

(a) General Development of Business. Dean Witter Principal Plus

Fund L.P. (the "Partnership") is a Delaware limited partnership

organized to engage primarily in the speculative trading of

futures contracts, options on futures contracts and physical

commodities, forward contracts, and other commodity interests.



The general partner for the Partnership is Demeter Management

Corporation ("Demeter"). The non-clearing commodity broker is

Dean Witter Reynolds Inc. ("DWR"). The clearing commodity

brokers are Morgan Stanley & Co. Incorporated ("MS & Co.") and

Morgan Stanley & Co. International Limited ("MSIL") which provide

clearing and execution services. Prior to May 2000, Carr Futures

Inc. provided clearing and execution services to the Partnership.

Demeter, DWR, MS & Co. and MSIL are wholly-owned subsidiaries of

Morgan Stanley Dean Witter & Co. ("MSDW"). The trading manager

to the Partnership is RXR Inc. (the "Trading Manager").



The Partnership's net asset value per unit of limited partnership

interest ("Unit(s)") at December 31, 2000, was $1,941.87,

representing an increase of 6.96 percent from the net asset value

per Unit of $1,815.50 at December 31, 1999. For a more detailed

description of the Partnership's business see subparagraph (c).







(b) Financial Information about Segments. For financial

information reporting purposes, the Partnership is deemed to

engage in one industry segment, the speculative trading of

futures, forwards, and options. The relevant financial

information is presented in Items 6 and 8.



(c) Narrative Description of Business. The Partnership is in

the business of speculative trading of futures, forwards, and

options, pursuant to trading instructions provided by its Trading

Manager. For a detailed description of the different facets of

the Partnership's business, see those portions of the

Partnership's prospectus, dated November 8, 1995 (the

"Prospectus"), incorporated by reference in this Form 10-K, set

forth below.

brokers) enters into forward contract transactions where foreign

banks are the contracting party and trades in futures, forwards,

and options on foreign exchanges.



Item 2. PROPERTIES

The executive and administrative offices are located within the

offices of DWR. The DWR offices utilized by the Partnership are

located at Two World Trade Center, 62nd Floor, New York, NY

10048.



Item 3. LEGAL PROCEEDINGS

Similar class actions were filed in 1996 in California and New

York State courts. Each of these actions were dismissed in 1999.

However, the New York State class action discussed below is still

pending because plaintiffs appealed the trial court's dismissal

of their case on March 3, 2000.



On September 18 and 20, 1996, purported class actions were filed

in the Supreme Court of the State of New York, New York County,

on behalf of all purchasers of interests in limited partnership

commodity pools sold by DWR. Named defendants include DWR,





Demeter, MSDW, certain limited partnership commodity pools of

which Demeter is the general partner and certain trading managers

to these pools. A consolidated and amended complaint in the

action pending in the Supreme Court of the State of New York was

filed on August 13, 1997, alleging that the defendants committed

fraud, breach of fiduciary duty, and negligent misrepresentation

in the sale and operation of the various limited partnership

commodity pools. The complaints sought specified amounts of

compensatory and punitive damages and other relief. The New York

Supreme Court dismissed the New York action in November 1998, but

granted plaintiffs leave to file an amended complaint, which they

did in early December 1998. The defendants filed a motion to

dismiss the amended complaint with prejudice on February 1, 1999.

By decision dated December 21, 1999, the New York Supreme Court

dismissed the case with prejudice. However on March 3, 2000,

plaintiffs appealed the trial court's dismissal of their case.



Item 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

None.

















PART II

Item 5. MARKET FOR THE REGISTRANT'S PARTNERSHIP UNITS AND
RELATED SECURITY HOLDER MATTERS



(a) Market Information

There is no established public trading market for Units of the

Partnership.



(b) Holders

The number of holders of Units at December 31, 2000 was

approximately 2,347.



(c) Distributions

No distributions have been made by the Partnership since it

commenced operations on February 14, 1990. Demeter has sole

discretion to decide what distributions, if any, shall be made to

investors in the Partnership. Demeter currently does not intend

to make any distribution of Partnership profits.

Item 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
CONDITION AND RESULTS OF OPERATIONS

Liquidity. The Partnership deposits its assets with DWR as non-

clearing broker and MS & Co. and MSIL as clearing brokers in

separate futures, forwards, and options 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 Commodity Futures Trading Commission ("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 and 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.



Capital Resources. The Partnership does not have, or expect to

have, any capital assets. Redemptions of Units in the future

will affect the amount of funds available for investments 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.



Results of Operations.

General. The Partnership's results depend on its 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, forwards, and options markets. The following presents a

summary of the Partnership's operations for the three years ended

December 31, 2000 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 its Trading Manager's trading

activities on behalf of the Partnership and how the Partnership

has performed in the past.




At December 31, 2000, the Partnership's total capital was

$39,470,347, a decrease of $4,442,369 from the Partnership's

total capital of $43,912,716 at December 31, 1999. For the year

ended December 31, 2000, the Partnership generated net income of

$3,386,012, and total redemptions aggregated $7,828,381.



For the year ended December 31, 2000, the Partnership recorded

total trading revenues, including interest income, of $3,942,875

and posted an increase in net asset value per Unit. Unrealized

gains recorded on the Yield Pool totaled $1,703,855. The

Partnership's exposure to Australian, European, Japanese and

North American fixed income markets added value to the global



interest rate futures markets sector with gains of approximately

5.9%. The currency sector also recorded gains of approximately

0.9% aided by a strengthening euro and a weakening Japanese yen.

The Partnership's exposure to the energy sector also performed

well with profits of approximately 1.2%, taking advantage of

falling crude oil inventories during the early part of the year

and reactionary supply boosts later in 2000. Conversely, equity

markets declined in all G4 economies, creating a subsequent

flight-to-quality and driving nominal interest rates lower in

most major money markets. The G4 economies are U.S., Japan,

Germany and Britain. As a result, losses of approximately 3.2%

were recorded in these markets. Exposure to agricultural

commodities markets under-performed slightly reflecting non-

directional price movement within the sector. The Partnership

experienced a profitable first quarter, despite tremendous

volatility in the U.S. stock market. The S&P 500 Index declined

through February but rallied to post a positive quarter and

enabled the hedged equity strategy to salvage a modest gain. The

Federal Reserve Bank raised the overnight borrowing rate by 50

basis points during the quarter responding to a perceived

inflationary threat. U.S. interest rates, however, continued to

decline benefiting the hedged fixed income component. The global

macro component also added value, enjoying most of its gains from

long futures positions in Sweden's OMX Index as the market

advanced throughout the quarter. The second quarter was a

sluggish one for the Partnership. The Federal Reserve Bank



decided to raise short-term rates by another 50 basis points at

its May meeting, which proved to be the last proactive move made

by the U.S. central bank in 2000. The hedged equity component

underperformed as U.S. stocks endured a modest decline. Treasury

bonds continued to strengthen and the hedged fixed income

strategy helped to buffer the Partnership. The global macro

component under-performed due to unexpected weakness in the U.S.

dollar and simultaneous strength in the euro. Conversely, long

futures positions in the crude oil complex performed well after

OPEC failed to raise output in a timely fashion. The

Partnership's performance was relatively flat for the third

quarter. U.S. interest rates fell by an average of 15 basis

points along the yield curve benefiting the hedged fixed income

strategy. Rising energy prices prompted the Clinton

Administration to release 30 million barrels of crude oil from

the Strategic Petroleum Reserve prior to the winter months. Long

futures positions in the energy sector were adversely affected by

this decision as crude oil prices fell. Short positions in

Australian financial futures also under-performed as the Reserve

Bank of Australia failed to make good on an expected interest

rate hike. The global macro component did enjoy gains from long

positions in copper futures along with short positions in New

Zealand dollar, South African rand and Australian dollar. The

Partnership posted a profitable fourth quarter due primarily to

performance in the global macro component. Interest rates fell

throughout the world, supporting the Partnership's long positions



in U.S., European and Australian financial futures. Long

positions in the Swiss franc and euro versus most major

currencies also added value. Long positions in natural gas

futures were profitable as prices rose due to a severe inventory

shortage, which was first noted in California and continued

spreading throughout the country. The S&P 500, DAX 30, FTSE 100

and Nikkei 225 Index all posted losses for the fourth quarter and

the year 2000. Total expenses for the year were $2,271,429,

resulting in income before minority interest of $3,375,301. The

minority interest in trading losses experienced outside the Yield

Pool was $10,711, resulting in net income of $3,386,012 for the

Partnership. The net asset value of a Unit increased from

$1,815.50 at December 31, 1999 to $1,941.87 at December 31, 2000.



At December 31, 1999, the Partnership's total capital was

$43,912,716, a decrease of $8,351,449 from the Partnership's

total capital of $52,264,165 at December 31, 1998. For the year

ended December 31, 1999, the Partnership generated a net loss of

$3,799,938, and total redemptions aggregated $4,551,511.



For the year ended December 31, 1999, the Partnership recorded

total trading revenues, including interest income, of $1,638,358

and posted a decrease in net asset value per Unit. Losses

recorded on the Yield Pool totaled $2,971,134. Extreme price

volatility in U.S. and Australian fixed income markets created

losses, while the Partnership's exposure to the U.S. equity and



energy markets and its net short exposure to European interest

rate sector helped steady performance. The most significant

losses of approximately 5.00% were experienced primarily during

February, April and May in the fixed income component of the

balanced portfolio from long U.S. interest rate futures positions

as prices dropped in reaction to Federal Reserve Chairman Alan

Greenspan's warnings in Congressional testimony in late February

that a strong economy could reignite inflation. Fears that the

Federal Reserve eventually could boost target interest rates

continued to push down domestic bond prices and forced yields

higher. Losses were also experienced in this market complex

during July and August after Federal Reserve Chairman Alan

Greenspan commented that central bankers must consider stock

prices when setting monetary policy and as reports on labor

costs, home sales, manufacturing and personal income added to

concern that the U.S. Federal Reserve will raise interest rates

soon. Mitigating gains of approximately 1.12% were recorded in

the energy markets primarily during March from long positions in

crude and gas oil futures as prices moved significantly higher

due largely to the news that both OPEC and non-OPEC countries had

reached an agreement to cut total output beginning April 1st.

Gains were also recorded in this market complex during the third

quarter after OPEC ministers confirmed that they would uphold

their global cutbacks until April of 2000. Reports of declining

crude oil and gasoline inventories also boosted oil prices during

the third quarter. Total expenses for the year were $2,589,673,



resulting in a net loss before minority interest of $3,922,449.

The minority interest in such losses was $122,511, resulting in a

net loss of $3,799,938 for the Partnership. The net asset value

of a Unit decreased from $1,887.62 at December 31, 1998 to

$1,815.50 at December 31, 1999.



At December 31, 1998, the Partnership's total capital was

$52,264,165, a decrease of $681,697 from the Partnership's total

capital of $52,945,862 at December 31, 1997. For the year ended

December 31, 1998, the Partnership generated net income of

$7,203,198, and total redemptions aggregated $7,884,895.



For the year ended December 31, 1998, the Partnership recorded

total trading revenues, including interest income, of $8,079,935

and posted an increase in net asset value per Unit. Gains

recorded on the Yield Pool totaled $2,163,176. The Partnership

profited during 1998, primarily from gains of approximately 6.27%

recorded in the global stock index futures markets. Long S&P 500

Index futures positions were profitable in the equity portion of

the portfolio as stock prices reached record levels during the

first half of the year, as well as closing the year with a move

higher. The global interest rate futures markets were also key

contributors to overall gains, recording gains of approximately

3.45% primarily from long global bond futures positions,







especially U.S., European and Japanese bond futures. Bond prices

benefited from a "flight-to-quality" during the third quarter

amid the world's shaky financial system and global economic

deterioration. Total expenses for the year were $2,958,490,

resulting in income before minority interest of $7,284,621. The

minority interest in such gains was $81,423, resulting in net

income of $7,203,198 for the Partnership. The net asset value of

a Unit in the Partnership increased from $1,707.59 at December

31, 1997 to $1,887.62 at December 31, 1998.



The Partnership's overall performance record represents varied

results of trading in different futures, forwards, and options

markets. For a further description of 2000 trading results,

refer to the letter to the Limited Partners in the accompanying

Annual Report to Limited Partners for the year ended December 31,

2000, which is incorporated by reference to Exhibit 13.01 of this

Form 10-K. The Partnership's gains and losses are allocated

among its partners for income tax purposes.



Credit Risk.

Financial Instruments. The Partnership is a party to financial

instruments with elements of off-balance sheet market and credit

risk. The Partnership may trade futures, forwards, and options

to gain long biased exposure to global stock markets and global

bond markets, as well as long and short exposure to a component

of managed futures contracts in agricultural commodities, energy



products, foreign currencies, precious and base metals, and soft

commodities. In entering into these contracts, the Partnership

is subject to the market risk that such contracts may be

significantly influenced by market conditions, such as interest

rate volatility, resulting in such contracts being less valuable.

If the markets should move against all of the positions held by

the Partnership at the same time, and if the Trading Manager was

unable to offset positions of the Partnership, the Partnership

could lose all of its assets and investors would realize a 100%

loss.



In addition to the Trading Manager's internal controls, the

Trading Manager must comply with the trading policies of the

Partnership. These trading policies include standards for

liquidity and leverage with which the Partnership must comply.

The Trading Manager and Demeter monitor the Partnership's trading

activities to ensure compliance with the trading policies.

Demeter may require the Trading Manager to modify positions of

the Partnership if Demeter believes they violate the

Partnership's trading policies.



In addition to market risk, in entering into futures, forwards,

and options contracts there is a credit risk to the Partnership

that the counterparty on a contract will not be able to meet its

obligations to the Partnership. The ultimate counterparty or

guarantor of the Partnership for futures contracts traded in the



United States and the foreign exchanges on which the Partnership

trades is the clearinghouse associated with such exchange. In

general, a clearinghouse is backed by the membership of the

exchange and will act in the event of non-performance by one of

its members or one of its member's customers, which should

significantly reduce this credit risk. For example, a

clearinghouse may cover a default by drawing upon a defaulting

member's mandatory contributions and/or non-defaulting members'

contributions to a clearinghouse guarantee fund, established

lines or letters of credit with banks, and/or the clearinghouse's

surplus capital and other available assets of the exchange and

clearinghouse, or assessing its members. In cases where the

Partnership trades off-exchange forward contracts with a

counterparty, the sole recourse of the Partnership will be the

forward contracts counterparty.



There is no assurance that a clearinghouse or exchange will meet

its obligations to the Partnership, and Demeter and the commodity

brokers will not indemnify the Partnership against a default by

such parties. Further, the law is unclear as to whether a

commodity broker has any obligation to protect its customers from

loss in the event of an exchange or clearinghouse defaulting on

trades effected for the broker's customers. Any such obligation

on the part of a broker appears even less clear where the default

occurs in a non-U.S. jurisdiction.





Demeter deals with these credit risks of the Partnership in

several ways. First, it monitors the Partnership's credit

exposure to each exchange on a daily basis, calculating not only

the amount of margin required for it but also the amount of its

unrealized gains at each exchange, if any. The commodity brokers

inform the Partnership, as with all their customers, of its net

margin requirements for all its existing open positions, but do

not break that net figure down, exchange by exchange. Demeter,

however, has installed a system which permits it to monitor the

Partnership's potential margin liability, exchange by exchange.

As a result, Demeter is able to monitor the Partnership's

potential net credit exposure to each exchange by adding the

unrealized trading gains on that exchange, if any, to the

Partnership's margin liability thereon.



Second, the Partnership's trading policies limit the amount of

its net assets that can be committed at any given time to futures

contracts and require, in addition, a minimum amount of

diversification in the Partnership's trading, usually over

several different products. One of the aims of such trading

policies has been to reduce the credit exposure of the

Partnership to a single exchange and, historically, the

Partnership's exposure to any one exchange has typically amounted

to only a small percentage of its total net assets. On those

relatively few occasions where the Partnership's credit exposure

may climb above that level, Demeter deals with the situation on a



case by case basis, carefully weighing whether the increased

level of credit exposure remains appropriate. Material changes

to the trading policies may be made only with the prior written

approval of the limited partners owning more than 50% of Units

then outstanding.



Third, with respect to forward contract trading, the Partnership

trades with only those counterparties which Demeter, together

with DWR, have determined to be creditworthy. The Partnership

presently deals with MS & Co. as the sole counterparty on forward

contracts.



See "Financial Instruments" under Notes to Financial Statements

in the Partnership's Annual Report to Limited Partners for the

year ended December 31, 2000, which is incorporated by reference

to Exhibit 13.01 of this Form 10-K.



Item 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET
RISK

Introduction

The Partnership is a commodity pool involved 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 experiences 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 using 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 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.



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.


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 December 31, 2000 and 1999.

At December 31, 2000 and 1999, the Partnership's total

capitalization was approximately $39 million and $44 million,

respectively.

Primary Market December 31, 2000 December 31, 1999
Risk Category Value at Risk Value at Risk

Interest Rate (0.87)% (0.14)%

Currency (0.35) (0.12)

Commodity (0.15) (0.12)

Equity (0.05) (0.33)

Aggregate Value at Risk (0.91)% (0.43)%

Aggregate Value at Risk represents the aggregate VaR of all the

Partnership's open positions and not the sum of the VaR of the

individual market categories listed above. Aggregate VaR will be

lower as it takes into account correlation among different

positions and categories.


The table above represents the VaR of the Partnership's open

positions at December 31, 2000 and 1999 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 December 31, 2000 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 January 1, 2000 through December 31, 2000.



Primary Market Risk Category High Low Average

Interest Rate (0.87)% (0.68)% (0.77)%

Currency (0.35) (0.19) (0.27)

Commodity (0.21) (0.15) (0.17)

Equity (0.59) (0.05) (0.30)

Aggregate Value at Risk (1.02)% (0.77)% (0.91)%




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 in response to 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 December 31, 2000 and for the end of the four

quarterly reporting periods during calendar year 2000. 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 1 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 December 31, 2000, the

Partnership's cash balance at DWR was approximately 8% 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.



The Partnership also has non-trading risk on the zero-coupon U.S.

Treasury Securities it holds to support the guaranteed net asset

value per Unit at the Guaranteed Redemption Date of August 31,

2003. The fair value of these securities is subject to interest

rate risk.



For non-trading securities, the Partnership measures its market

risk using sensitivity analysis. The sensitivity analysis

estimates the potential change in fair value based on a

hypothetical 10% change in interest rates. Based on the current

valuation of the Zero-Coupon U.S. Treasury Securities, such a

change in interest rates will cause an approximately (5.68)%

decline in their fair value. Such a change will not have a

material effect on the net asset value per Unit.



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.



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 expropri-

ations, 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 as of December 31, 2000, by market sector. It may be

anticipated however, that these market exposures will vary

materially over time.



Interest Rate. The largest market exposure at December 31, 2000

was in the global interest rate complex. Exposure was primarily

spread across the U.S. and European 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 United States and the other G-7 countries.

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 changes in interest rates which have the most effect

on the Partnership are changes in long-term, as opposed to short-

term, rates. Most of the speculative futures positions held by

the Partnership are in medium- to long-term instruments.

Consequently, even a material change in short-term rates would





have little effect on the Partnership, were the medium- to long-

term rates to remain steady.



Currency. The Partnership's currency exposure at December 31,

2000 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 in a large number of

currencies, including cross-rates - i.e., positions between two

currencies other than the U.S. dollar. For the fourth quarter of

2000, 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 dollar-based Partnership in

expressing VaR in a functional currency other than dollars.



Commodity.

Energy. On December 31, 2000, the Partnership's energy exposure

was shared primarily by futures contracts in the crude oil and

natural gas markets. Price movements in these markets result



from political developments in the Middle East, weather patterns,

and other economic fundamentals. It is possible that volatility

will remain high. Significant profits and losses, which have

been experienced in the past, are expected to continue to be

experienced in this market. Natural gas has exhibited volatility

in prices resulting from weather patterns and supply and demand

factors and may continue in this choppy pattern.



Soft Commodities and Agriculturals . On December 31, 2000, the

Partnership had exposure in the corn, cattle, and cotton markets.

Supply and demand inequalities, severe weather disruption and

market expectations affect price movements in these markets.



Metals. The Partnership's metals market exposure at December 31,

2000 was to fluctuations in the price of base metals. During

period of volatility, base metals will affect performance

dramatically. Demeter anticipates that the base metals will

remain the primary metals market exposure of the Partnership.



Equity. The primary equity exposure at December 31, 2000 was to

equity price risk in the G-7 countries. The G-7 countries

consist of France, U.S., Britain, Germany, Japan, Italy and

Canada. The stock index futures traded by the Partnership are by

law limited to futures on broadly based indices. As of December

31, 2000, the Partnership's primary exposures were in the S&P 500

(U.S.) and Nikkei (Japan) stock indices. The Partnership is



primarily exposed to the risk of adverse price trends or static

markets in the U.S. and Japanese 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.



Qualitative Disclosures Regarding Non-Trading Risk Exposure

The following were the only non-trading risk exposures of the

Partnership at December 31, 2000:



Foreign Currency Balances. The Partnership's primary

foreign currency balances at December 31, 2000 were in

Australian dollars, euros, Japanese yen and South African

rands. The Partnership controls the non-trading risk of

these balances by regularly converting these balances back

into dollars upon liquidation of the respective position.



Zero-Coupon U.S. Treasury Securities. It is the

Partnership's intention to hold the Zero-Coupon U.S.

Treasury Securities until their August 15, 2003 maturity

date except as needed to fund quarterly redemptions.

Consequently, the period to period interest rate risk these

securities are subject to is not considered material.



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 instruments, cash and Zero-Coupon U.S. Treasury

Securities. Cash and Zero-Coupon U.S. Treasury Securities are

the only Partnership investments directed by Demeter, rather than

the Trading Manager.

trading results for the year is provided in the Annual Report of the Trading
Manager located on the next page of this report.

Should you have any questions concerning this report, please feel free to con-

Annual Report of the Trading Manager

Principal Plus Fund's Net Asset Value gained in the year 2000. The Fund's ex-
posure to Australian, European, Japanese and North American fixed income mar-
kets added value, as did the currency sector aided by a strengthening euro and
a weakening Japanese yen late in the year. The Fund's exposure to the energy
sector also performed well, taking advantage of falling crude oil inventories
during the early part of the year and reactionary supply boosts later in 2000.
Conversely, equity markets declined in all G4 economies, creating a subsequent
flight-to-quality and driving nominal interest rates lower in most major money
markets. The G4 economies are U.S., Japan, Germany and Britain. Exposure to
agricultural commodities markets under-performed, reflecting non-directional
price movement within the sector.

The Fund experienced a profitable first quarter, despite tremendous volatility
in the U.S. stock market. The S&P 500 Index declined through February but ral-
lied to post a positive quarter and enabled the hedged equity strategy to sal-
vage a modest gain. The Federal Reserve Bank raised the overnight borrowing
rate by 50 basis points during the quarter responding to a perceived infla-
tionary threat. U.S. interest rates, however, continued to decline benefiting
the hedged fixed income component. The global macro component also added val-
ue, enjoying most of its gains from long futures positions in Sweden's OMX In-
dex as the market advanced throughout the quarter.

The second quarter was a sluggish one for the Fund. The Federal Reserve Bank
decided to raise short-term rates by another 50 basis points at its May meet-
ing, which proved to be the last proactive move made by the U.S. central bank
in 2000. The hedged equity component under-performed as U.S. stocks endured a
modest decline. Treasury bonds continued to strengthen and the hedged fixed
income strategy helped to buffer the Fund. The global macro component under
performed due to unexpected weakness in the U.S. dollar and simultaneous
strength in the euro. Conversely, long futures positions in the crude oil com-
plex performed well after OPEC failed to raise output in a timely fashion.

The Fund's performance was relatively flat for the third quarter. U.S. inter-
est rates fell by an average of 15 basis points along the yield curve benefit-
ing the hedged fixed

income strategy. Rising energy prices prompted the Clinton Administration to
release 30 million barrels of crude oil from the Strategic Petroleum Reserve
prior to the winter months. Long futures positions in the energy sector were
adversely affected by this decision as crude oil prices fell. Short positions
in Australian financial futures also under-performed as the Reserve Bank of
Australia failed to make good on an expected interest rate hike. The global
macro component did enjoy gains from long positions in copper futures along
with short positions in New Zealand dollar, South African rand and Australian
dollar.

The Fund posted a profitable fourth quarter due primarily to performance in
the global macro component. Interest rates fell throughout the world, support-
ing the Fund's long positions in U.S., European and Australian financial
futures. Long positions in the Swiss franc and euro versus most major curren-
cies also added value. Long positions in natural gas futures were profitable
as prices rose due to a severe inventory shortage, which was first noted in
California and continued spreading throughout the country. The S&P 500, DAX
30, FTSE 100 and Nikkei 225 Index all posted losses for the fourth quarter and
the year 2000.

We thank you for your continued support and look forward to serving your in-
vestment needs in 2001.

Independent Auditors' Report

The Limited Partners and the General Partner:

We have audited the accompanying consolidated statements of financial condi-
tion of Dean Witter Principal Plus Fund L.P. and subsidiary (the "Partner-
ship") as of December 31, 2000 and 1999 and the related consolidated state-
ments of operations, changes in partners' capital, and cash flows for each of
the three years in the period ended December 31, 2000. These consolidated fi-
nancial statements are the responsibility of the Partnership's management. Our
responsibility is to express an opinion on these consolidated financial state-
ments based on our audits.

We conducted our audits in accordance with auditing standards generally ac-
cepted in the United States of America. Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the finan-
cial statements are free of material misstatement. An audit includes examin-
ing, on a test basis, evidence supporting the amounts and disclosures in the
financial statements. An audit also includes assessing the accounting princi-
ples used and significant estimates made by management, as well as evaluating
the overall financial statement presentation. We believe that our audits pro-
vide a reasonable basis for our opinion.

In our opinion, such consolidated financial statements present fairly, in all
material respects, the consolidated financial position of Dean Witter Princi-
pal Plus Fund L.P. and subsidiary at December 31, 2000 and 1999 and the con-
solidated results of their operations and their cash flows for each of the
three years in the period ended December 31, 2000 in conformity with account-
ing principles generally accepted in the United States of America.

Dean Witter Principal Plus Fund L.P.
Notes to Consolidated Financial Statements

1. Summary of Significant Accounting Policies

Organization--Dean Witter Principal Plus Fund L.P. (the "Partnership") is a
limited partnership organized to engage primarily in the speculative trading
of futures contracts, options on futures contracts and physical commodities,
forward contracts, and other commodity interests (collectively, "futures in-
terests").

The Partnership's objective is to achieve long-term appreciation while assur-
ing investors at least a 3% compound annual rate of return over approximately
seven and one-half years from February 1, 1996 to August 31, 2003. At August
31, 2003, which is the Partnership's "Guaranteed Redemption Date," the Net As-
set Value is guaranteed to be at least $1,961.00 per Unit. The Partnership in-
itially invested approximately 80% of the Partnership's assets in Zero-Coupon
U.S. Treasury Securities (the "Yield Pool") to accomplish this objective. The
Partnership's remaining assets have been contributed to its subsidiary, Dean
Witter Principal Plus Fund Management L.P. (the "Trading Company"), which was
established solely to trade in futures interests on behalf of the Partnership.

The general partner for the Partnership is Demeter Management Corporation
("Demeter"). The non-clearing commodity broker is Dean Witter Reynolds Inc.
("DWR"). Morgan Stanley & Co., Inc. ("MS&Co.") and Morgan Stanley & Co. Inter-
national Limited ("MSIL") provide clearing and execution services. Prior to
May 2000, Carr Futures Inc. ("Carr") provided clearing and execution services
to the Partnership. Demeter, DWR, MS&Co. and MSIL are wholly-owned subsidiar-
ies of Morgan Stanley Dean Witter & Co. ("MSDW"). The trading manager to the
Partnership is RXR Inc. (the "Trading Manager").

Effective February 19, 1998, Morgan Stanley, Dean Witter, Discover & Co.
changed its corporate name to Morgan Stanley Dean Witter & Co.

Demeter is required to maintain a 1% minimum interest in the equity of the
Partnership and income (losses) are shared by Demeter and the Limited Partners
based upon their proportional ownership interests.

Use of Estimates--The financial statements are prepared in accordance with ac-
counting principles generally accepted in the United States of America, which
require management to make estimates and assumptions that affect the reported
amounts in the financial statements and related disclosures. Management be-
lieves that the estimates utilized in the preparation of the financial state-
ments are prudent and reasonable. Actual results could differ from those esti-
mates.


Dean Witter Principal Plus Fund L.P.
Notes to Consolidated Financial Statements--
(Continued)


Principles of Consolidation--The consolidated financial statements include the
accounts of the Partnership and the Trading Company. All intercompany balances
have been eliminated.

The ownership by Demeter in the Trading Company represents a minority interest
in the Partnership. Demeter's share of the Trading Company's profits and loss-
es is deducted from consolidated results of operations.

Revenue Recognition--The yield pool is valued at cost plus accreted interest
with the accumulated unrealized gain (loss) on the zero-coupon U.S. Treasury
Securities separately disclosed. The annual change in the yield pool's market
value is reflected in the consolidated statements of operations. The consoli-
dated statements of financial condition and the consolidated statements of op-
erations have been reconciled to reflect Net Assets, Net Asset Value per Unit
and Net Income (Loss) in accordance with the terms of the Limited Partnership
Agreement.

The following information pertains to the Yield Pool at December 31, 2000 and
1999:


2000 1999
---------- ----------

$ $
Year to Date Accreted Interest Income 2,108,883 2,303,952
Cost of Yield Pool at year-end 27,062,738 32,415,109
Accreted Interest Receivable at year-end 8,593,114 7,952,427
Market Value of Yield Pool at year-end 36,341,317 39,349,146


Futures interests are open commitments until settlement date. They are valued
at market on a daily basis and the resulting net change in unrealized gains
and losses is reflected in the change in unrealized profit (loss) on open con-
tracts from one period to the next in the consolidated statements of opera-
tions.

Monthly, DWR pays interest income on 90% of the Trading Company's average dai-
ly Net Assets as defined in the Limited Partnership Agreement for the month at
a prevailing rate on U.S. Treasury bills. For purposes of such interest pay-
ments, Net Assets do not include monies due the Trading Company on futures in-
terests, but not actually received.

Net Income (Loss) per Unit--Net income (loss) per unit of limited partnership
interest ("Unit(s)") is computed using the weighted average number of Units
outstanding during the period.

Equity in Futures Interests Trading Accounts--The Partnership's asset "Equity
in futures interests trading accounts," reflected in the consolidated state-
ments of financial condition,


Dean Witter Principal Plus Fund L.P.
Notes to Consolidated Financial Statements--
(Continued)

consists of (A) cash on deposit with DWR, MS&Co. and MSIL to be used as margin
for trading; (B) net unrealized gains or losses on open contracts which are
valued at market, and calculated as the difference between original contract
value and market value, and (C) net option premiums, which represent the net
of all monies paid and/or received for such option premiums.

The Partnership, in the normal course of business, enters into various con-
tracts with MS&Co. and MSIL acting as its commodity brokers. Pursuant to bro-
kerage agreements with MS&Co. and MSIL, to the extent that such trading re-
sults in unrealized gains or losses, the amounts are offset and reported on a
net basis on the Partnership's consolidated statements of financial condition.

The Partnership has offset the fair value amounts recognized for forward con-
tracts executed with the same counterparty as allowable under terms of the
master netting agreement with MS&Co., the sole counterparty on such contracts.
The Partnership has consistently applied its right to offset.

Brokerage Fees and Related Transaction Fees and Costs--The monthly brokerage
fee is equal to 1/3 of 1% per month (a 4% annual rate) of the Partnership's
adjusted month-end Net Assets. Transaction fees and costs are accrued on a
half-turn basis. In 2000, the brokerage fee charged was the equivalent of a
roundturn commission charge of approximately $157 per contract traded.

Operating Expenses--The Partnership bears all operating expenses related to
its trading activities. These include filing fees, clerical, administrative,
auditing, accounting, mailing, printing and other incidental operating ex-
penses as permitted by the Limited Partnership Agreement. In addition, the
Partnership incurs a monthly management fee and may incur an incentive fee.
Demeter bears all other operating expenses.

Redemptions--As of the last day of any calendar quarter, Limited Partners may
redeem some or all of their Units at 100% of the Net Asset Value per Unit upon
five business days advance notice by redemption form to Demeter.

During 2000 and 1999, the Partnership sold securities in the Yield Pool in or-
der to fund redemptions as detailed below:



2000 1999
--------- ---------

Cost of Securities Sold 5,352,371 1,927,054
Interest Accreted on Securities Sold 1,468,197 610,556
Proceeds from Sale of Securities 6,700,824 3,549,406



Dean Witter Principal Plus Fund L.P.
Notes to Consolidated Financial Statements--
(Continued)


Distributions--The Partnership will not make any distributions until after the
Guarantee Period, and thereafter will only make distributions on a pro-rata
basis at the sole discretion of Demeter.

Income Taxes--No provision for income taxes has been made in the accompanying
consolidated financial statements, as partners are individually responsible
for reporting income or loss based upon their respective share of the Partner-
ship's revenues and expenses for income tax purposes.

Dissolution of the Partnership--The Partnership will terminate on December 31,
2025, or at an earlier date if certain conditions set forth in the Limited
Partnership Agreement occur.

The Trading Company may terminate operations if its Net Assets decline to 5%
or less of consolidated Partnership Net Assets, and will terminate operations
if its Net Assets decline to less than 3% of consolidated Partnership Net As-
sets. At December 31, 2000 and 1999, the Trading Company had Net Assets of
$4,941,558 and $4,761,650 respectively, which represented 12% and 11% respec-
tively, of the consolidated Partnership's Net Assets at the respective dates.
If the operations of the Trading Company ceased, the remaining Net Assets
would be returned to the Partnership and held until the end of the Guarantee
Period, when they would be distributed to the Limited Partners.

2. Related Party Transactions

The Trading Company pays a monthly brokerage fee to DWR as described in Note
1. The Partnership's and Trading Company's cash is on deposit with DWR,
MS&Co., and MSIL in futures interests trading accounts to meet margin require-
ments as needed. DWR pays interest on these funds as described in Note 1. The
Yield Pool is on deposit with DWR in a customer security account. Pursuant to
the Limited Partnership Agreement, Demeter initially invested $200,000 of
General Partnership Interest in the Trading Company.

3. Trading Manager

Compensation to RXR as trading manager consists of a management fee and an in-
centive fee as follows:

Management Fee--The Partnership pays a monthly management fee equal to 1/12 of
1% per month (a 1% annual rate) of the Partnership's adjusted Net Assets, as
defined in the Limited Partnership Agreement, as of the last day of each
month.


Dean Witter Principal Plus Fund L.P.
Notes to Consolidated Financial Statements--
(Continued)


Incentive Fee--The Partnership will pay an annual incentive fee to RXR equal
to 15% of the "New Appreciation", as defined in the Limited Partnership Agree-
ment, of the Trading Company's Net Assets as of the end of each annual incen-
tive period ending December 31. Such incentive fee is accrued in each month in
which New Appreciation occurs. In those months in which New Appreciation is
negative, previous accruals, if any, during the incentive period will be re-
duced.

4. Financial Instruments

The Partnership trades futures contracts, options on futures contracts and
physical commodities, forward contracts, 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 of the contracts. There are numerous factors which may significantly in-
fluence the market value of these contracts, including interest rate volatili-
ty.

In June 1998, the Financial Accounting Standards Board ("FASB") issued State-
ment of Financial Accounting Standard ("SFAS") No. 133, "Accounting for Deriv-
ative Instruments and Hedging Activities" effective for fiscal years beginning
after June 15, 2000, as amended by SFAS No. 137. The Partnership adopted the
provisions of SFAS No. 133 beginning with the fiscal year ended December 31,
1998. SFAS No. 133 superceded SFAS Nos. 119 and 105, which required the dis-
closure of average aggregate fair values and contract/notional values, respec-
tively, of derivative financial instruments for an entity that carries its as-
sets at fair value. SFAS No. 133 was further amended by SFAS No. 138, which
clarifies issues surrounding interest rate risk, foreign currency denomina-
tions, normal purchases and sales and net hedging. The application of SFAS No.
133, as amended by SFAS No. 137 and SFAS No. 138, did not have a significant
effect on the Partnership's financial statements.

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 Principal Plus Fund L.P.
Notes to Consolidated Financial Statements--
(Continued)

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

The net unrealized gains on open contracts are reported as a component of "Eq-
uity in futures interests trading accounts" on the statements of financial
condition and totaled $1,629,964 and $380,736 at December 31, 2000 and 1999,
respectively.

Of the $1,629,964 net unrealized gain on open contracts at December 31, 2000,
$1,650,388 related to exchange-traded futures contracts and $(20,424) related
to off-exchange-traded forward currency contracts.

Of the $380,736 net unrealized gain on open contracts at December 31, 1999,
$325,528 related to exchange-traded futures contracts and $55,208 related to
off-exchange-traded forward currency contracts.

Exchange-traded futures contracts held by the Partnership at December 31, 2000
and 1999 mature through June 2001 and June 2000, respectively. Off-exchange-
traded forward currency contracts held by the Partnership at December 31, 2000
and 1999 mature through March 2001 and March 2000, respectively.

The Partnership has credit risk associated with counterparty nonperformance.
The credit risk associated with the instruments in which the Partnership is
involved is limited to the amounts reflected in the Partnership's consolidated
statements of financial condition.

The Partnership also has credit risk because DWR, 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 con-
tracts are marked to market on a daily basis, with variations in value settled
on a daily basis. DWR, MS&Co. and MSIL, each as a futures commission merchant
for all of the Partnership's exchange-traded futures and futures-styled op-
tions contracts, are required, pursuant to regulations of the Commodity
Futures Trading Commission, 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 option contracts including an
amount equal to the net unrealized gain on all open futures and futures-styled
option contracts, which funds, in the aggregate, totaled $5,068,219 and
$6,339,551 at December 31, 2000 and 1999, respectively. With respect to the
Partnership's off-exchange-traded forward currency contracts, there are no
daily settle-

ments of variations in value nor is there any requirement that an amount equal
to the net unrealized gain on open forward contracts be segregated. With re-
spect 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 con-
tracts, 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 insolven-
cy.

5. Legal Matters

Similar class actions were filed in 1996 in California and New York State
courts. Each of the actions were dismissed in 1999. However, the New York
State class action discussed below is still pending because plaintiffs ap-
pealed the trial court's dismissal of their case on March 3, 2000.

On September 18 and 20, 1996, purported class actions were filed in the Su-
preme Court of the State of New York, New York County, on behalf of all pur-
chasers of interests in limited partnership commodity pools sold by DWR. Named
defendants include DWR, Demeter, Dean Witter Futures & Currency Management
Inc., MSDW, certain limited partnership commodity pools of which Demeter is
the general partner and certain trading managers to those pools. A consolidat-
ed and amended complaint in the action pending in the Supreme Court of the
State of New York was filed on August 13, 1997, alleging that the defendants
committed fraud, breach of fiduciary duty, and negligent misrepresentation in
the sale and operation of the various limited partnership commodity pools. The
complaints sought unspecified amounts of compensatory and punitive damages and
other relief. The New York Supreme Court dismissed the New York action in No-
vember 1998, but granted plaintiffs leave to file an amended complaint, which
they did in early December 1998. The defendants filed a motion to dismiss the
amended complaint with prejudice on February 1, 1999. By decision dated Decem-
ber 21, 1999, the New York Supreme Court dismissed the case with prejudice.
However, on March 3, 2000 plaintiffs appealed the trial courts dismissal of
their case.
