Annual Report to Dean
Witter
Diversified Futures Fund
Limited Partnership Limited Partners for
the year ended December 31, 1999 II, III, and
IV



























PART I

Item 1. BUSINESS

(a) General Development of Business. Dean Witter Diversified

Futures Fund Limited Partnership (the "Partnership") is a

Delaware limited partnership organized to engage primarily in the

speculative trading of futures and forward contracts, physical

commodities and other commodity interests, including foreign

currencies, financial instruments, metals, energy products and

agriculturals (collectively, "futures interests").



The general partner for the Partnership is Demeter Management

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

Dean Witter Reynolds Inc. ("DWR") and an unaffiliated clearing

commodity broker, Carr Futures Inc. ("Carr"), provides clearing

and execution services. The trading manager is Dean Witter

Futures & Currency Management Inc. ("DWFCM" or the "Trading

Manager"). Demeter, DWR and DWFCM are wholly-owned subsidiaries

of Morgan Stanley Dean Witter & Co. ("MSDW").



The Partnership's Net Asset Value per unit of limited partnership

interest ("Unit(s)"), as of December 31, 1999, was $963.26

representing a decrease of 11.1 percent from the Net Asset Value

per Unit of $1,084.04 at December 31, 1998. For a more detailed

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





(b) Financial Information about Industry Segments. For financial

information reporting purposes, the Partnership is deemed to

engage in one industry segment, the speculative trading of

futures interests. 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 interests, pursuant to

trading instructions provided by the Trading Manager. For a

detailed description of the different facets of the Partnership's

business, see those portions of the Partnership's Prospectus

dated June 30, 1995, (the "Prospectus"), incorporated by

reference in this Form 10-K, set forth below.

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

The class actions first filed in 1996 in California and in New

York State courts were each dismissed in 1999. However, in the

New York State class action, plaintiffs appealed the trial

court's dismissal of their case on March 3, 2000.



On September 6, 10, and 20, 1996, and on March 13, 1997,

purported class actions were filed in the Superior Court of the

State of California, County of Los Angeles, on behalf of all

purchasers of interests in limited partnership





commodity pools sold by DWR. Named defendants include DWR,

Demeter, DWFCM, MSDW, the Partnership, certain limited

partnership commodity pools of which Demeter is the general

partner (all such parties referred to hereafter as the "Morgan

Stanley Dean Witter Parties") and certain trading advisors to

those pools. On June 16, 1997, the plaintiffs in the above

actions filed a consolidated amended complaint, alleging, among

other things, that the defendants committed fraud, deceit,

negligent misrepresentation, various violations of the California

Corporations Code, intentional and negligent breach of fiduciary

duty, fraudulent and unfair business practices, unjust

enrichment, and conversion in the sale and operation of the

various limited partnership commodity pools. The complaints seek

unspecified amounts of compensatory and punitive damages and

other relief. The court entered an order denying class

certification on August 24, 1999. On September 24, 1999, the

court entered an order dismissing the case without prejudice on

consent. Similar purported class actions were also filed on

September 18 and 20, 1996, in the Supreme Court of the State of

New York, New York County, and on November 14, 1996 in the

Superior Court of the State of Delaware, New Castle County,

against the Morgan Stanley Dean Witter Parties and certain

trading advisors on behalf of all purchasers of interests in

various limited partnership commodity pools, including the

Partnership, sold by DWR. 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 seek unspecified 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.



In addition, on December 16, 1997, upon motion of the plaintiffs,

the action pending in the Superior Court of the State of Delaware

was voluntarily dismissed without prejudice.



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

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 Carr as clearing broker in separate futures

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, and forwards, it is expected that the Partnership will

continue to own such liquid assets for margin purposes.



The Partnership's investment in futures and forwards may, from

time to time, be illiquid. Most U.S. futures exchanges limit

fluctuations in prices during a single day by regulations

referred to as "daily price fluctuations limits" or "daily

limits". Trades may not be executed at prices beyond the daily

limit. If the price for a particular futures contract has

increased or decreased by an amount equal to the daily limit,

positions in that futures contract can neither be taken nor

liquidated unless traders are willing to effect trades at or

within the limit. Futures prices have occasionally moved the

daily limit for several consecutive days with little or no

trading. These market conditions





could prevent the Partnership from promptly liquidating its

futures contracts and result in restrictions on redemptions.



There is no limitation on daily price moves in trading forward

contracts on foreign currencies. The markets for some world

currencies have low trading volume and are illiquid, which may

prevent the Partnership from trading in potentially profitable

markets or prevent the Partnership from promptly liquidating

unfavorable positions in such markets 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 interests 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, 1999 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 as a whole and how the

Partnership has performed in the past.




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

$91,649,223, a decrease of $36,197,354 from the Partnership's

total capital of $127,846,577 at December 31, 1998. For the year

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

$13,289,436, and total redemptions aggregated $22,907,918.







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

total trading losses, net of interest income, of $2,601,037 and

posted a decrease in Net Asset Value per Unit. The Partnership

experienced losses in the global interest rate futures markets,

approximately 10.23%, primarily from short Australian interest

rate futures positions as prices increased during July and August

on the temporary strength in U.S. bonds and weaker-than-expected

business spending data out of Australia. Additional losses were

recorded from short Japanese bond futures positions as prices

increased during the first quarter and third quarters. In the

currency markets, losses of approximately 7.21% were recorded

primarily from Australian dollar positions. Throughout a

majority of the first quarter, losses were experienced from long

Australian dollar positions as its value dropped significantly

relative to the U.S. dollar on speculation regarding potential

currency devaluations in the Asian region. Early in the third

quarter, additional losses were recorded from long positions in

this currency due to depressed commodities prices, emerging

market concerns and on-going talks that China may eventually

devalue its currency. Newly established short positions in the

Australian dollar resulted in losses during September as

its value strengthened relative to the U.S. dollar following the

rally in gold prices. Offsetting currency gains of 3.76% were

recorded from Japanese yen positions, primarily long positions.

During the third quarter, gains were recorded from long positions

in the Japanese yen as the value of the yen climbed to a 44-month

high versus the U.S. dollar due to continued optimism





over Japan's economic recovery. The energy markets produced

gains of approximately 7.60%. During March, gains were recorded

from long positions in oil futures as prices moved significantly

higher on 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 next year. Total expenses for the

year were $10,688,399, resulting in a net loss of $13,289,436.

The value of a Unit decreased from $1,084.04 at December 31, 1998

to $963.26 at December 31, 1999.



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

$127,846,577, a decrease of $17,705,046 from the Partnership's

total capital of $145,551,623 at December 31, 1997. For the year

ended December 31, 1998, the Partnership generated net income of

$6,976,181, and total redemptions aggregated $24,681,227.



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

total trading revenues, including interest income, of $19,531,954

and posted an increase in Net Asset Value per Unit. Gains of

approximately 13.96% were recorded in the global interest rate

futures markets from bond futures in most major world countries

throughout the year. The most significant gains were recorded in

German bond futures, by approximately 5.83%, U.S. bond futures,

by approximately 3.92% and Japanese bond futures, by

approximately 3.41% from



primarily long positions during August and September as investors

sought the safety of fixed income investments from notable

volatility in the global financial markets. Additional profits

were recorded from short Japanese government bond futures

positions during December as prices declined amid a surge in

Japanese bond yields, which was attributed to news that Japan's

Ministry of Finance will end outright purchases of government

debt. Total expenses for the year were $12,555,773, resulting in

net income of $6,976,181. The value of a Unit increased from

$1,020.54 at December 31, 1997 to $1,084.04 at December 31, 1998.



At December 31, 1997, the Partnership's total capital was

$145,551,623, a decrease of $18,135,532 from the Partnership's

total capital of $163,687,155, at December 31, 1996. For the

year ended December 31, 1997, the Partnership generated net

income of $17,349,458 and total redemptions aggregated

$35,484,990.



For the year ended December 31, 1997, the Partnership recorded

total trading revenues, including interest income, of $33,683,534

and posted an increase in Net Asset Value per Unit. 1997 was a

profitable year for the Partnership. Gains of approximately

19.09% were recorded in the currency markets primarily from

sustained price movements during January and February and then

again in November and December from short Japanese yen positions

as the value of the U.S. dollar increased versus the yen. A

portion of the Partnership's overall



gains was offset by losses of approximately 4.84% recorded in the

global interest rate futures markets primarily due to a sharp

trend reversal in international interest rate futures prices

during the fourth quarter and as a result of short-term

volatility in domestic bond and stock index futures. Offsetting

gains were recorded from long global interest rate futures

positions during June and July. Although, many of the profitable

periods with long price trends were followed by trend reversals

and short-term volatile price movement, DWFCM's intermediate to

long-term trend following trading methodology was able to retain

profits. Total expenses for the year were $16,334,076,

resulting in net income of $17,349,458. The value of a Unit

increased from $911.49 at December 31, 1996 to $1,020.54 at

December 31, 1997.



The Partnership's overall performance record represents varied

results of trading in different futures interest markets. For a

further description of 1999 trading results, refer to the letter

to the Limited Partners in the accompanying Annual Report to

Limited Partners for the year ended December 31, 1999, 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 in a portfolio of

agricultural commodities, energy products, foreign currencies,

interest rates, precious and base metals, soft commodities, and

stock indices. 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, Demeter has secured, with respect to Carr acting as the

clearing broker for the Partnership, a guarantee by Credit

Agricole Indosuez, Carr's parent, of the payment of the "net

liquidating value" of the transactions (futures and forward

contracts) in the Partnership's account.



With respect to forward contract trading, the Partnership trades

with only those counterparties which Demeter, together with DWR,

have determined to be creditworthy. At the date of this filing,

the Partnership deals only with Carr as its counterparty on

forward contracts. The guarantee by Carr's parent, discussed

above, covers these 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, 1999, which is incorporated by reference

to Exhibit 13.01 of this Form

10-K.



Year 2000. Commodity pools, like financial and business

organizations and individuals around the world, depend on the

smooth functioning of computer





systems. The Year 2000 issue arose since many of the world's

computer systems (including those in non-information technology

systems) traditionally recorded years in a two-digit format. If

not addressed, such computer systems may have been unable to

properly interpret dates beyond the year 1999, which may have led

to business disruptions in the U.S. and internationally. Such

disruptions could have adversely affected the handling or

determination of futures trades and prices and other services for

the Partnership. Accordingly, Demeter has fully participated in

a firmwide initiative established by MSDW to address issues

associated with the Year 2000. As part of this initiative, MSDW

reviewed its global software and hardware infrastructure for

mainframe, server and desktop computing environments and engaged

in extensive remediation and testing. The Year 2000 initiative

also encompassed the review of agencies, vendors and facilities

for Year 2000 compliance.



Since 1995, MSDW prepared actively for the Year 2000 issue to

ensure that it would have the ability to respond to any critical

business process failure, to prevent the loss of workspace and

technology, and to mitigate any potential financial loss or

damage to its global franchise. Where necessary, contingency

plans were expanded or developed to address specific Year 2000

risk scenarios, supplementing existing business policies and

practices. In conjunction with MSDW's Year 2000 preparations,

Demeter monitored the progress of Carr and each Trading Manager

throughout 1999 in their Year 2000 compliance and, where

applicable, tested its external interfaces, with Carr and the



Trading Manager. In addition, Demeter, the commodity brokers,

the Trading Manager and all U.S. futures exchanges were subjected

to monitoring by the CFTC of their Year 2000 preparedness, and

the major foreign futures exchanges engaged in market-wide

testing of their Year 2000 compliance during 1999.



MSDW and Demeter consider the transition into the Year 2000

successful from the perspective of their internal systems and

global external interactions. Over the millennial changeover

period, no material issues were encountered, and MSDW, Demeter

and the Partnership conducted business as usual.



Risks Associated With the Euro. On January 1, 1999, eleven

countries in the European Union established fixed conversion

rates on their existing sovereign currencies and converted to a

common single currency (the euro). During a three-year

transition period, the sovereign currencies will continue to

exist but only as a fixed denomination of the euro. Conversion

to the euro prevents the Trading Manager from trading those

sovereign currencies and thereby limits its ability to take

advantage of potential market opportunities that might otherwise

have existed had separate currencies been available to trade.

This could adversely affect the performance results of the

Partnership.


Item 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET
RISK

Introduction

The Partnership is a commodity pool involved in the speculative

trading of



futures interests. 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 interests traded by the Partnership involve varying

degrees of 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 interests 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 tables indicates the VaR associated with the

Partnership's open positions as a percentage of total Net Assets

by primary market risk category as of December 31, 1999 and 1998.

As of December 31, 1999 and 1998, the Partnership's total

capitalization was approximately $92 million and $128 million,

respectively.

Primary Market December 31, 1999
December 31, 1998
Risk Category Value at Risk Value at
Risk

Interest Rate (.55)% (.57)%

Currency (2.27) (.93)

Commodity (2.43) (1.07)

Equity (.45) (.24)

Aggregate Value at Risk (3.67)%

(1.41)%



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, 1999 and 1998 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 interests, 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 year 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 January

1, 1999 through December 31, 1999.



Primary Market Risk Category High Low

Average

Interest Rate (2.01)% (.55)% (1.11)%

Currency (2.27) (1.69) (1.96)

Commodity (2.43) (.93) (1.44)

Equity (.77) (.19) (.48)

Aggregate Value at Risk (3.67)% (2.26)% (2.89)%



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, gives

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, 1999 and for the end of the four

quarterly reporting periods during calendar year 1999. 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. The Partnership also

maintains a substantial portion (approximately 90%) of its

available assets in cash at DWR. 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

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.





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

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 as of December 31, 1999, by market sector. It may be

anticipated however, that these market exposures will vary

materially over time.





Interest Rate. The largest exposure this quarter was in the

interest rate sector. Exposure was spread across the U.S., Swiss,

Australian, and Japanese interest rate sectors. Interest rate

movements directly affect the price of the sovereign bond

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 G-7 countries

and Australia. The G-7 countries consist of France, U.S.,

Britain, Germany, Japan, Italy and Canada. Demeter anticipates

that G-7 and Australian 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 and medium-

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 next most significant exposure in the Partnership

is in the currency complex. The Partnership's currency exposure

is to exchange rate fluctuations, primarily fluctuations that

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

1999, the Partnership's foreign currency exposure was in the euro

currency crosses and outright U.S. dollar positions (outright

positions consist of the U.S. dollar vs. other currencies). 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.

Metals. The next noteworthy exposure was in the base and

precious metals markets. The Partnership's metals market exposure

in the fourth quarter of 1999 was to fluctuations in the prices

of base metals, as well as exposure in the gold and silver

markets. A significant amount of exposure was evident in the

base metals as the Partnership held sizeable positions due to a

period of low volatility prior to the upward price breakout.



The Partnership aims to equally weight market exposure in the

metals as much as possible, however base metals, during periods

of volatility, will affect performance more dramatically than the

precious metals markets. Demeter anticipates that base metals

will remain the primary metals market exposure of the

Partnership.



Energy. On December 31, 1999, the Partnership's energy exposure

was in futures contracts in the New York and Brent crude oil

markets. Price movements in these markets result from political

developments in the Middle East, weather patterns, and other

economic fundamentals. As oil prices have increased over 100%

this year, and, given that the agreement by OPEC to cut

production is closing in on expiring in March of 2000, it is

possible that volatility will remain on the high end. Significant

profits and losses have been and are expected to continue to be

experienced in these markets.



Soft Commodities. On December 31, 1999, the Partnership had

moderate exposure in the markets that comprise these sectors.

Most of the exposure however was in the cotton and sugar markets.

Supply and demand inequalities, severe weather disruptions and

market expectations affect price movements in these markets.



Equity. The Partnership's equity exposure on December 31, 1999

to price risk in the S&P 500 futures index was noteworthy. The

stock index futures traded by the Partnership are by law limited

to futures on broadly based indices. Demeter anticipates little,

if any, trading in non G-7 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 was the only non-trading risk exposure of the

Partnership as of December 31, 1999:



Foreign Currency Balances. The Partnership's foreign currency

balances are in Japanese yen, British pounds, euros, Swiss francs

and Australian dollars. The Partnership controls the non-trading

risk of these balances by regularly converting these balances

back into dollars upon liquidation of the respective position.



Qualitative Disclosures Regarding Means of Managing Risk Exposure

The Partnership and the Trading Manager, separately, attempt to

manage the risk of the Partnership's open positions in

essentially the same manner in all market categories traded.

Demeter attempts to manage market exposure by diversifying the

Partnership's assets among different market sectors and trading

approaches and monitoring the performance of the Trading Manager

daily. In addition, the Trading Manager establishes

diversification guidelines, often set in terms of the maximum

margin to be committed to positions in any one market sector or

market-sensitive instrument.



Demeter monitors and controls the risk of the Partnership's non-

trading instrument, cash, which is the only Partnership

investment directed by Demeter, rather than the Trading Manager.



Item 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

The Financial Statements are incorporated by reference to the

Partnership's Annual Report, which is filed as Exhibit 13.01

hereto.



Supplementary data specified by Item 302 of Regulation S-K

(selected quarterly financial data) is not applicable.

Dean Witter Diversified Futures Fund Limited Partnership
Annual Report
1999

Dear Limited Partner:

This marks the twelfth annual report for the Dean Witter Diversified Futures
Fund Limited Partnership (the "Fund"). The Fund began the year at a Net Asset
Value per Unit of $1,084.04 and decreased by 11.1% to $963.26 on December 31,
1999. The Fund has increased by 281.9% since it began trading in April 1988 (a
compound annualized return of 12.1%).

Overall, the Fund experienced difficulty in the global interest rate futures
markets primarily from short Australian interest rate futures positions as
prices increased during July and August on the temporary strength in U.S. bonds
and weaker-than-expected business spending data out of Australia. Additional
losses were recorded from short Japanese bond futures positions as prices
increased during the first quarter and the third quarter. In the currency
markets, losses were recorded throughout the majority of the first quarter from
long Australian dollar positions as its value dropped significantly relative to
the U.S. dollar on speculation regarding potential currency devaluations in the
Asian region. Early in the third quarter, losses were recorded from long
positions in this currency due to depressed commodities prices, emerging market
concerns and on-going talks that China may eventually devalue its currency.
Newly established short positions in the Australian dollar resulted in
additional losses during September as its value strengthened relative to the
U.S. dollar following the rally in gold prices. Offsetting currency gains were
recorded during the third quarter from long positions in the Japanese yen as
the value of the yen climbed to a 44-month high versus the U.S. dollar due to
continued optimism over Japan's


economic recovery. The energy markets were profitable during March from long
positions in oil futures as prices moved significantly higher on 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 during the third
quarter after OPEC ministers confirmed that they would uphold their global
cutbacks until April of 2000.

While we are disappointed that the Fund had a difficult year in 1999, we remind
investors that managed futures funds such as Diversified Futures Fund are de-
signed to provide diversification and non-correlation, that is, the ability to
perform independently, of global equities and bonds. Managed futures have his-
torically performed independently of traditional investments, such as stocks
and bonds. This is referred to as non-correlation, or the potential for managed
futures to perform when traditional markets such as stocks and bonds may expe-
rience difficulty performing. Of course, managed futures funds will not auto-
matically be profitable during unfavorable periods for these traditional in-
vestments and vice versa. The degree of non-correlation of any given managed
futures fund will vary, particularly as a result of market conditions, and some
funds will have significantly lesser degrees of non-correlation (i.e., greater
correlation) with stocks and bonds than others. Managed futures have histori-
cally performed independently of traditional investments, such as stocks and
bonds. 1999 proved to be another strong year for equities, due in large part to
continued growth and stability in most major world economies accompanied by low
inflation. This environment, while strong for equities, provided few major sus-
tained price trends in the world's futures and currency markets, and as such,
proved to be a difficult trading environment for the money manager in this
Fund, whose trading strategy relies on the existence of longer-term price
trends for trading opportunities. Nevertheless, we remain confident in the role
that managed futures investments play in the overall investment portfolio, and
we believe this confidence is well-founded based on the longer-term diversified
non-correlated returns of this alternative investment. Demeter Management Cor-
poration, as General Partner to the Fund, has been and continues to be


an active investor with more than $18 million invested among the 24 managed
futures funds to which we act as General Partner.

Should you have any questions concerning this report, please feel free to con-
tact Demeter Management Corporation at Two World Trade Center, 62nd Floor, New
York, NY 10048 or your Morgan Stanley Dean Witter Financial Advisor.

I hereby affirm, that to the best of my knowledge and belief, the information
contained in this report is accurate and complete. Past performance is not a
guarantee of future results.

Independent Auditors' Report

The Limited Partners and the General Partner:

We have audited the accompanying statements of financial condition of Dean Wit-
ter Diversified Futures Fund Limited Partnership (the "Partnership") as of De-
cember 31, 1999 and 1998 and the related statements of operations, changes in
partners' capital, and cash flows for each of the three years in the period
ended December 31, 1999. These financial statements are the responsibility of
the Partnership's management. Our responsibility is to express an opinion on
these financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing stan-
dards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of mate-
rial misstatement. An audit includes examining, on a test basis, evidence sup-
porting the amounts and disclosures in the financial statements. An audit also
includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement pre-
sentation. We believe that our audits provide a reasonable basis for our opin-
ion.

In our opinion, such financial statements present fairly, in all material re-
spects, the financial position of Dean Witter Diversified Futures Fund Limited
Partnership at December 31, 1999 and 1998 and the results of its operations and
its cash flows for each of the three years in the period ended December 31,
1999 in conformity with generally accepted accounting principles.

Dean Witter Diversified Futures Fund
Limited Partnership

Notes to Financial Statements

1. Summary of Significant Accounting Policies

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

The general partner for the Partnership is Demeter Management Corporation ("De-
meter"). The non-clearing commodity broker is Dean Witter Reynolds Inc. ("DWR")
and an unaffiliated clearing commodity broker, Carr Futures Inc. ("Carr"), pro-
vides clearing and execution services. The trading manager is Dean Witter
Futures & Currency Management Inc. ("DWFCM" or the "Trading Manager"). Demeter,
DWR and DWFCM are wholly-owned subsidiaries of Morgan Stanley Dean Witter & Co.
("MSDW").

On May 31, 1997, Morgan Stanley Group Inc. was merged with and into Dean Wit-
ter, Discover & Co. ("DWD"). At that time DWD changed its corporate name to
Morgan Stanley, Dean Witter, Discover & Co. ("MSDWD"). Effective February 19,
1998, MSDWD 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 gen-
erally accepted accounting principles, which require management to make esti-
mates and assumptions that affect the reported amounts in the financial state-
ments and related disclosures. Management believes that the estimates utilized
in the preparation of the financial statements are prudent and reasonable. Ac-
tual results could differ from those estimates.

Revenue Recognition--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 are reflected in the change in unrealized profit
(loss) on open contracts from one period to the next in the statements of oper-
ations. Monthly, DWR pays the Partnership interest income based upon 80% of its
average daily Net Assets for the month


Dean Witter Diversified Futures Fund
Limited Partnership

Notes to Financial Statements--(Continued)

at a prevailing rate for U.S. Treasury bills. For purposes of such interest
payments, Net Assets do not include monies due the Partnership 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 statements of finan-
cial condition, consists of (A) cash on deposit with DWR and Carr to be used as
margin for trading and (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.

The Partnership, in the normal course of business, enters into various con-
tracts with Carr acting as its commodity broker. Pursuant to brokerage agree-
ments with Carr, to the extent that such trading results in unrealized gains or
losses, the amounts are offset and reported on a net basis in the Partnership's
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 mas-
ter netting agreement with Carr, the sole counterparty on such contracts. The
Partnership has consistently applied its right to offset.

Brokerage Commissions and Related Transaction Fees and Costs--Brokerage commis-
sions are accrued at 80% of DWR's published non-member rates on a half-turn ba-
sis. Transaction fees and costs are accrued on a half-turn basis. Brokerage
commissions and transaction fees combined are capped at 13/20 of 1% per month
(a maximum 7.8% annual rate) of the Partnership's Net Assets as of the last day
of each month.

Operating Expenses--The Partnership bears all expenses related to its trading
activities. Such fees are capped at a maximum of 1/4 of 1% annually of the
Partnership's average monthly Net Assets as of the first day of each month.
These include legal, auditing, accounting, mailing, printing, filing fees and
other expenses as permitted by the Limited Partnership Agreement. In addition,
the Partnership incurs a monthly management fee and may incur incentive fees.
Demeter bears all other operating expenses.


Dean Witter Diversified Futures Fund
Limited Partnership

Notes to Financial Statements--(Continued)

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

Distributions--Distributions, other than redemptions of Units, are made on a
pro-rata basis at the sole discretion of Demeter. No distributions have been
made to date.

Redemptions--Limited Partners may redeem some or all of their Units at 100% of
the Net Asset Value per Unit as of the end of any month upon five business days
advance notice by redemption form to Demeter.

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

2. Related Party Transactions

The Partnership pays brokerage commissions to DWR as described in Note 1. The
Partnership's cash is on deposit with DWR and Carr in futures interests trading
accounts to meet margin requirements as needed. DWR pays interest on these
funds as described in Note 1.

Demeter, on behalf of the Partnership and itself, has entered into a Management
Agreement with DWFCM to make all trading decisions for the Partnership.

Compensation to DWFCM by the Partnership consists of a management fee and an
incentive fee as follows:

Management Fee--The monthly management fee is accrued daily at the rate of 1/4
of 1% per beginning of the month Net Assets (a 3% annual rate), as defined in
the Management Agreement.

Incentive Fee--The Partnership will pay a quarterly incentive fee equal to 15%
of the trading profits earned by the Partnership as of the end of each calendar
quarter. Trading profits represent the amount by which profits from futures and
forward trading exceed losses after brokerage commissions, management fee,
transaction fees and costs and administrative expenses are deducted. Such in-
centive fee is accrued in each month in which trading profits occur. In those
months in which trading profits are negative, previous accruals, if any, during
the quarter will be reduced.

3. Financial Instruments

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

In June 1998, the Financial Accounting Standards Board ("FASB") issued State-
ment of Financial Accounting Standard ("SFAS") No. 133, "Accounting for Deriva-
tive Instruments and Hedging Activities" effective for fiscal years beginning
after June 15, 1999. In June 1999, the FASB issued SFAS No. 137, "Accounting
for Derivative Instruments and Hedging Activities--Deferral of the Effective
Date of SFAS No. 133," which defers the required implementation of SFAS No. 133
until fiscal years beginning after June 15, 2000. However, the Partnership had
previously elected to adopt the provisions of SFAS No. 133 beginning with the
fiscal year ended December 31, 1998. SFAS No. 133 supercedes SFAS No. 119 and
No. 105, which required the disclosure of average aggregate fair values and
contract/notional values, respectively, of derivative financial instruments for
an entity which carries its assets at fair value. The application of SFAS No.
133 does not have a significant effect on the Partnership's financial
statements.

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 con-
dition and totaled $1,601,939 and $1,784,289 at December 31, 1999 and 1998, re-
spectively.

Of the $1,601,939 net unrealized gain on open contracts at December 31, 1999,
$1,280,887 related to exchange-traded futures contracts and $321,052 related to
off-exchange-traded forward currency contracts.

Of the $1,784,289 net unrealized gain on open contracts at December 31, 1998,
$6,485,141 related to exchange-traded futures contracts and $(4,700,852) re-
lated to off-exchange-traded forward currency contracts.

Exchange-traded futures contracts held by the Partnership at December 31, 1999
and 1998 mature through Sep-tember 2000 and June 1999, respectively. Off-ex-
change-


Dean Witter Diversified Futures Fund
Limited Partnership

Notes to Financial Statements--(Continued)

traded forward currency contracts held by the Partner-ship at December 31, 1999
and 1998 mature through March 2000 and March 1999, respectively.

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

The Partnership also has credit risk because DWR and Carr act as the futures
commission merchants or the counterparties, with respect to most of the Part-
nership's assets. Exchange-traded futures contracts are marked to market on a
daily basis, with variations in value settled on a daily basis. Each of DWR and
Carr, as a futures commission merchant for the Partnership's exchange-traded
futures 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 contracts including an amount equal to the net
unrealized gain on all open futures contracts, which funds, in the aggregate,
totaled $93,374,811 and $134,032,614 at December 31, 1999 and 1998, respective-
ly. With respect to the Partnership's off-exchange-traded forward currency con-
tracts, there are no daily settlements 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 respect to those off-exchange-traded forward cur-
rency contracts, the Partnership is at risk to the ability of Carr, the sole
counterparty on all of such contracts, to perform. The Partnership has a net-
ting agreement with Carr. This agreement, which seeks to reduce both the Part-
nership's and Carr's exposure on off-exchange-traded forward currency con-
tracts, should materially decrease the Partnership's credit risk in the event
of Carr's bankruptcy or insolvency. Carr's parent, Credit Agricole Indosuez,
has guaranteed to the Partnership payment of the net liquidating value of the
transactions in the Partnership's account with Carr (including foreign currency
contracts).

4. Legal Matters

The class actions first filed in 1996 in California and in New York State
courts were each dismissed in 1999. On September 6, 10, and 20, 1996, and on
March 13, 1997, purported class actions were filed in the Superior Court of the
State of California, County of Los Angeles, on


Dean Witter Diversified Futures Fund
Limited Partnership

Notes to Financial Statements--(Continued)

behalf of all purchasers of interests in limited partnership commodity pools
sold by DWR. Named defendants include DWR, Demeter, DWFCM, MSDW, the Partner-
ship, certain limited partnership commodity pools of which Demeter is the gen-
eral partner (all such parties referred to hereafter as the "Morgan Stanley
Dean Witter Parties") and certain trading advisors to those pools. On June 16,
1997, the plaintiffs in the above actions filed a consolidated amended com-
plaint alleging, among other things, that the defendants committed fraud, de-
ceit, negligent misrepresentation, various violations of the California Corpo-
rations Code, intentional and negligent breach of fiduciary duty, fraudulent
and unfair business practices, unjust enrichment, and conversion in the sale
and operation of the various limited partnership commodity pools. The com-
plaints seek unspecified amounts of compensatory and punitive damages and other
relief. The court entered an order denying class certification on August 24,
1999. On September 24, 1999, the court entered an order dismissing the case
without prejudice on consent. Similar purported class actions were also filed
on September 18, and 20, 1996, in the Supreme Court of the State of New York,
New York County, and on November 14, 1996 in the Superior Court of the State of
Delaware, New Castle County, against the Morgan Stanley Dean Witter Parties and
certain trading advisors on behalf of all purchasers of interests in various
limited partnership commodity pools, including the Partnership, sold by DWR. 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 defen-
dants committed fraud, breach of fiduciary duty, and negligent misrepresenta-
tion in the sale and operation of the various limited partnership commodity
pools. The complaints seek unspecified amounts of compensatory and punitive
damages and other relief. The New York Supreme Court dismissed the New York ac-
tion in November 1998, but granted plaintiffs leave to file an amended com-
plaint, 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.

In addition, on December 16, 1997, upon motion of the plaintiffs, the action
pending in the Superior Court of the State of Delaware was voluntarily dis-
missed without prejudice.
