Fund L.P.



























PART I

Item 1. BUSINESS

(a) General Development of Business. Dean Witter

Portfolio Strategy Fund L.P. (formerly Dean Witter Principal

Secured Futures Fund L.P.) (the "Partnership") is a Delaware

limited partnership formed to engage in the speculative

trading of commodity futures contracts and other commodity

interests, including, but not limited to, forward contracts

on foreign currencies and options on futures contracts and

physical commodities (collectively, "futures interests").

Units of limited partnership interest (Units) in the

Partnership were registered pursuant to a Registration

Statement on Form S-1 (File No. 33-36656) which became

effective on October 30, 1990. The offering of Units was

underwritten on a "best efforts" basis by Dean Witter

Reynolds Inc. ("DWR"). The Partnership's general partner is

Demeter Management Corporation ("Demeter"). DWR and Demeter

are wholly-owned subsidiaries of Morgan Stanley, Dean

Witter, Discover & Co. ("MSDWD"). The Partnership commenced

operations on February 1, 1991. 50,000 additional Units in

the Partnership were registered pursuant to the Registration

Statement on Form S-1 (File No. 333-24109) which became

effective on May 12, 1997.

Through July 31, 1997, the sole commodity broker for the

Partnership's transactions was DWR. On July 31, 1997, DWR

closed the sale of its institutional futures business and

foreign currency trading operations to Carr Futures, Inc. ("Carr"),

a subsidiary of Credit Agricole Indosuez. Following the sale, Carr

became the clearing commodity broker for the Partnership's futures





and futures options trades and the counterparty on the Partnership's

foreign currency trades. DWR serves as the non-clearing

commodity broker for the Partnerships with Carr providing

all clearing services for the Partnerships' transactions.

The Partnership's net asset value per unit, as of

December 31, 1997, was $2,373.36, representing an increase

of 11.27 percent from the net asset value per unit of

$2,132.79 at December 31, 1996. For a more detailed

description of the Partnership's business see subparagraph

(c).

(b) Financial Information about Industry Segments. The

Partnership's business comprises only one segment for

financial reporting purposes, speculative trading of

commodity futures contracts and other commodity 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 in commodity

futures interests, pursuant to trading instructions provided

by John W. Henry & Company, Inc. ("JWH") its independent

trading advisor. For a detailed description of the

different facets of the Partnership's business, see those

portions of the Partnership's Prospectus, dated May 12,

1997, filed as part of the Registration Statement on Form S-

1 (see "Documents Incorporated by Reference" Page 1), set

forth on the next page.

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

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

1997, similar purported class actions were filed in the

Superior Court of the State of California, County of Los

Angeles, on behalf of all purchasers of interest in limited

partnership commodity pools sold by DWR. Named defendants

include DWR, Demeter, Dean Witter Futures & Currency

Management Inc. ("DWFCM"), MSDWD (all such parties referred

to hereafter as the "Dean Witter Parties"), the Partnership

(under its original name), certain other limited partnership

commodity pools of which Demeter is the general partner, and

certain trading advisors (including JWH), 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. 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 Dean Witter Parties and certain trading advisors (including JWH)

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. 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. The complaints seek

unspecified amounts of compensatory and punitive damages and

other relief. It is possible that additional similar

actions may be filed and that, in the course of these

actions, other parties could be added as defendants. The

Dean Witter Parties believe that they and the Partnership

have strong defenses to, and they will vigorously contest,

the actions. Although the ultimate outcome of legal

proceedings cannot be predicted with certainty, it is the

opinion of management of the Dean Witter Parties that the

resolution of the actions will not have a material adverse

effect on the financial condition or the results of

operations of any of the Dean Witter Parties or the

Partnership.







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

There is no established public trading market for the

Units of Limited Partnership Interest in the Partnership.

The number of holders of Units at December 31, 1997 was

approximately 8,101. No distributions have been made by the

Partnership since it commenced trading operations on

February 1, 1991. Demeter has sole discretion to decide

what distributions, if any, shall be made to investors in

the Partnership. No determination has yet been made as to

future distributions.

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

Liquidity. The Partnership's assets are on deposit in

separate commodity interest trading accounts with DWR and

Carr, the commodity brokers, and are used by the Partnership

as margin to engage in commodity futures, forward contracts

and other commodity interest trading. DWR and Carr hold

such assets in either designated depositories or in

securities approved by the Commodity Futures Trading

Commission ("CFTC") for investment of customer funds. The

Partnership's assets held by DWR and Carr may be used as

margin solely for the Partnership's trading. Since the

Partnership's sole purpose is to trade in commodity futures

contracts, forward contracts on foreign currencies and other

commodity interests, it is expected that the Partnership

will continue to own such liquid assets for margin purposes.

The Partnership's investment in commodity futures

contracts, forward contracts and other commodity interests

may be illiquid. If the price for a futures contract for a

particular commodity has increased or decreased by an amount

equal to the "daily limit", positions in the commodity can

neither be taken nor liquidated unless traders are willing

to effect trades at or within the limit. Commodity futures

prices have occasionally moved the daily limit for several

consecutive days with little or no trading. Such market

conditions could prevent the Partnership from promptly

liquidating its commodity futures positions.





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.

Market Risk. The Partnership trades futures, options

and forward contracts in interest rates, stock indices,

commodities and currencies. In entering into these

contracts there exists a risk to the Partnership (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 futures interest

positions held by the Partnership at the same time, and if

the Trading Advisor were unable to offset futures interest

positions of the Partnership, the Partnership could lose all

of its assets and the Limited Partners would realize a 100%

loss. The Partnership has established Trading Policies,

which include standards for liquidity and leverage which

help control market risk. Both the Trading Advisor and

Demeter monitor the Partnership's trading activities on a

daily basis to ensure compliance with the Trading Policies.

Demeter may





(under terms of the Management Agreement) override the

trading instructions of the Trading Advisor to the extent

necessary to comply with the Partnership's Trading Policies.

Credit Risk. In addition to market risk, in entering

into futures, options and forward 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 of a Partnership for

futures contracts traded in the United States and most

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, and, as such,

should significantly reduce this credit risk. For example,

a clearinghouse may cover a default by (i) 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 (ii)

assessing its members. In cases where the Partnership

trades on a foreign exchange where the clearinghouse is not

funded or guaranteed by the membership or where the exchange

is a "principals' market" in which performance is the

responsibility of the exchange member and not the exchange

or a clearinghouse, or when the Partnership enters into off-



exchange contracts with a counterparty, the sole recourse of

the Partnership will be the clearinghouse, the exchange

member or the off-exchange contract counterparty, as the

case may be.

There can be no assurance that a clearinghouse,

exchange or other exchange member will meet its obligations

to the Partnership, and the Partnership is not indemnified

against a default by such parties from Demeter or MSDWD or

DWR. 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, clearinghouse or other exchange

member default on trades effected for the broker's

customers; any such obligation on the part of the broker

appears even less clear where the default occurs in a non-US

jurisdiction.

Demeter deals with these credit risks of the

partnerships in several ways. First, it monitors each

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 each

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

each partnership's potential margin liability, exchange by

exchange. Demeter is then able to monitor the individual

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, as discussed earlier, each partnership's

trading policies limit the amount of partnership Net Assets

that can be committed at any given time to futures contracts

and require, in addition, a certain 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 any

partnership to any single exchange and, historically, such

partnership exposure has typically amounted to only a small

percentage of its total Net Assets. On those relatively few

occasions where a partnership's credit exposure has climbed

above that level, Demeter has dealt with the situations on a

case by case basis, carefully weighing whether the increased

level of credit exposure remained appropriate. Demeter

expects to continue to deal with such situations in a

similar manner in the future.

Third, Demeter has secured, with respect to Carr acting

as the clearing broker for the partnerships, a guarantee by

Credit Agricole Indosuez, Carr's parent, of the payment of

the "net liquidating value" of the transactions (futures,

options and forward contracts) in each partnership's

account. As of December 31, 1997, Credit Agricole







Indosuez' total capital was over $3.25 billion and it is

currently rated AA2 by Moody's.

With respect to forward contract trading, the

partnerships trade with only those counterparties which

Demeter, together with DWR, have determined to be

creditworthy. At the date of this filing, the partnerships

deal only with Carr as their 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

1997 Annual Report to Partners, incorporated by reference in

this Form 10-K.

Capital Resources. The Partnership does not have, nor

does it expect to have, any capital assets. Redemptions and

sales of additional Units of Limited Partnership Interest in

the future will affect the amount of funds available for

investments in subsequent periods. As redemptions are at

the discretion of Limited Partners, it is not possible to

estimate the amount and therefore, the impact of future

redemptions.

Results of Operations. As of December 31, 1997, the

Partnership's total capital was $133,632,644, an increase of

$46,320,501 from the Partnership's total capital of

$87,312,143, at December 31, 1996. For











the year ended December 31, 1997, the Partnership generated

DEAN WITTER PORTFOLIO STRATEGY FUND L.P.
(FORMERLY DEAN WITTER PRINCIPAL SECURED FUTURES FUND L.P.) ANNUAL REPORT
1997

Dear Limited Partner:

This marks the seventh annual report for the Dean Witter Portfolio Strategy
Fund L.P. (the "Fund"). Please note, as stated in the Fund's prospectus dated
May 12, 1997, effective with the closing of re-offering of the Fund on July 31,
1997, assets were allocated to the following five John W. Henry & Company Inc.
trading programs in equal increments (20% each): Original Investment Program,
Financial and Metals Portfolio, the World Financial Perspective, Global
Financial Portfolio, and International Currency and Bond Portfolio. The Fund
began the year trading at a Net Asset Value per Unit of $2,132.79 and increased
by 11.2% to $2,373.36 on December 31, 1997. Since its inception in 1991, the
Fund has increased by 137.3% (a compound annualized return of 13.3%).

In January, the Fund posted gains as the value of the U.S. dollar increased
relative to the Japanese yen and German mark. Additional gains were recorded
from short gold futures positions as prices declined to their lowest levels in
over three years. The Fund recorded small losses during February as gains from
a continued strengthening of the U.S. dollar were offset by losses from
trendless price movement in the global interest rate futures and metals
markets. During March, the Fund experienced losses from short positions in
energies due to a reversal higher in oil and gas prices early in the month.
Losses were also recorded from long positions in nickel futures as prices
decreased and from trading gold futures as


prices moved in a choppy pattern. Losses were also recorded from short
positions in the German mark.

During April, the Fund recorded losses from long positions in Japanese
government bond futures as prices in this market moved lower. Additional losses
were recorded from short U.S. interest rate futures positions as domestic bond
prices spiked higher during the last week of April after moving lower
previously. During May, the Fund experienced significant losses primarily from
trading the Japanese yen as its value moved without consistent direction.
Smaller losses were recorded from short-term volatile price movement in crude
oil and gold futures. The Fund recorded profits in June primarily from long
positions in Australian and U.S. interest rate futures as prices moved higher.
Additional gains were recorded from long positions in global stock index
futures as most global equity prices moved higher. Smaller gains were recorded
from short gold futures positions.

The Fund recorded significant gains during July from long global bond futures
positions as prices trended higher. Additional gains were recorded in the
currency markets from short German mark and Swiss franc positions as the value
of the U.S. dollar strengthened versus these currencies. A portion of July's
profits was given back during August as prices of most global interest rate
futures reversed lower. Additional losses were recorded in the energy markets
as oil prices moved without consistent direction. In September, the Fund
recorded small losses primarily from transactions involving the British pound
and Swiss franc, as the value of these currencies moved in a trendless pattern.
Additional losses were recorded in energies as oil prices moved without
consistent direction. A majority of these losses was offset by gains recorded
from an upward price move in international interest rate futures.



The Fund recorded gains in currencies during the month of October as a result
of a weakening of the British pound relative to the U.S. dollar. Additional
gains were recorded from long positions in both Japanese and U.S. interest rate
futures as prices in these markets trended upward. In November, the Fund
recorded gains from short Japanese yen positions as the yen's value weakened
versus the U.S. dollar on continued concerns regarding the Asian economic
crisis. Additional gains were experienced from short positions in gold futures
as prices dropped below $300 an ounce, their lowest level in twelve years.
Gains in December were experienced primarily from long silver futures positions
as prices increased on reports of declining inventories. Additional gains were
recorded from long positions in U.S. and European interest rate futures as
prices in these markets increased due to a "flight to quality" by investors in
lieu of the economic turmoil in Asia. Smaller gains were recorded from short
positions in crude oil futures.

Overall, the Fund recorded strong gains in 1997 from sustained price movements
in the currency markets during January and February, and then again in the
fourth quarter from short Japanese yen positions as the value of the U.S.
dollar increased versus the yen. Additional gains were also recorded from long
positions in global interest rate futures as prices in these markets trended
upward during June and July. These gains, coupled with John W. Henry & Company,
Inc.'s ability to limit losses during periods of short-term price volatility
and sharp trend reversals, contributed to the overall success of the Fund
during the year.

DEAN WITTER PORTFOLIO STRATEGY FUND L.P.
NOTES TO FINANCIAL STATEMENTS

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

ORGANIZATION--Dean Witter Portfolio Strategy Fund L.P. (formerly Dean Witter
Principal Secured Futures Fund L.P.) (the "Partnership") is a limited
partnership organized to engage in the speculative trading of commodity futures
contracts, commodity options contracts and forward contracts on foreign
currencies. The general partner for the Partnership is Demeter Management
Corporation ("Demeter"). Demeter is a wholly owned subsidiary of Morgan
Stanley, Dean Witter, Discover & Co. ("MSDWD").

On May 31, 1997, Morgan Stanley Group Inc. was merged with and into Dean
Witter, Discover & Co. ("DWD"). At the time DWD changed its corporate name to
Morgan Stanley, Dean Witter, Discover & Co.

Demeter has retained John W. Henry & Company, Inc. ("JWH") as the trading
manager of the Partnership.

Through July 31, 1997, the sole commodity broker for the Partnership's
transactions was Dean Witter Reynolds Inc. ("DWR"), also a subsidiary of MSDWD.
On July 31, 1997, DWR closed the sale of its institutional futures business and
foreign currency trading operations to Carr Futures, Inc. ("Carr"), a
subsidiary of Credit Agricole Indosuez. Following the sale, Carr became the
clearing commodity broker for the Partnership's futures and futures options
trades and the counterparty on the Partnership's foreign currency trades. DWR
will continue to serve as the non-clearing commodity broker for the Partnership
with Carr providing all clearing services for the Partnership's transactions.

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

On July 31, 1996, with the Partnership's Net Asset Value above $1,000 per unit,
the letter of credit arrangement which assured investors who redeemed their
units on July 31, 1996 a minimum Net Asset Value of $1,000 per unit expired. On
August 1, 1996, the Partnership was renamed and continued trading in a non-
guaranteed format. Both the reduction of interest income of 1.125% per annum
for the letter of credit fee paid by DWR and the letter of credit fee of 1% of
new appreciation were eliminated effective August 1, 1996.


DEAN WITTER PORTFOLIO STRATEGY FUND L.P.
NOTES TO FINANCIAL STATEMENTS--(CONTINUED)

OFFERING OF UNITS--Additional Units were offered to the public at a price equal
to 100% of the Net Asset Value as of the close of business on the last day of
the month prior to the August 1, 1997 closing date of the offering.

BASIS OF ACCOUNTING--The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts in the financial statements.

REVENUE RECOGNITION--Commodity futures contracts and forward contracts on
foreign currencies are open commitments until settlement date. They are valued
at market and the resulting unrealized gains and losses are reflected in
income. Prior to August 1, 1996, DWR paid the Partnership interest income based
upon 80% of the average daily Net Assets for the month that was allocated to
JWH's KT Diversified Program, Financial and Metals Portfolio, International
Foreign Exchange Program, and The World Financial Perspective at a rate equal
to the average yield on 13-week U.S. Treasury Bills issued during such month
less a monthly letter of credit fee paid by DWR. DWR paid Citibank, N.A.
("Citibank") on the twentieth day of each month a Letter of Credit fee of 3/32
of 1% per month of the amount available to be drawn under the Letter of Credit.
Such amounts for the period ended July 31, 1996 and the year ended December 31,
1995 were $306,187 and $586,638, respectively. Additionally, DWR paid the
Partnership interest income based upon 100% of the Partnership's average daily
Net Assets which were allocated to the InterRate(TM) trading program for the
month at a rate equal to the average yield on 13-week U.S. Treasury Bills
issued during such month. For purposes of such interest payments, Net Assets
did not include monies due the Partnership on forward contracts and other
commodity interests, but not actually received.

Effective August 1, 1996, DWR pays the Partnership monthly interest income
based upon 80% of the average daily Net Assets for the month 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 forward contracts and other
commodity interests, but not actually received.

NET INCOME (LOSS) PER UNIT--Net income (loss) per Unit is computed using the
weighted average number of units outstanding during the period.

EQUITY IN COMMODITY FUTURES TRADING ACCOUNTS--The Partnership's asset "Equity

trading accounts" consists of cash on deposit at DWR and Carr to be used as
margin for trading and the net asset or liability related to unrealized gains
or losses on open contracts. The asset or liability related to the unrealized
gains or losses on forward contracts is presented as a net amount in each
period due to master netting agreements.

BROKERAGE COMMISSIONS AND RELATED TRANSACTION FEES AND COSTS--The Partnership
accrues brokerage commissions on a half-turn basis at 80% of DWR's published
non-member rates. Transaction fees and costs are accrued on a half-turn basis.

Prior to September 1, 1996 brokerage commissions were capped at 3/4 of 1% per
month of the Partnership's Net Assets as defined in the Limited Partnership
Agreement. Additionally, each trading program's brokerage commissions were
capped at 1% per month of the Net Assets allocated to such trading program.

Effective September 1, 1996, brokerage commissions and transaction fees
chargeable to the Partnership were capped at 13/20 of 1% per month of the
Partnership's month-end Net Assets (as defined in the Limited Partnership
Agreement) with such cap applied on a per trading program basis.

OPERATING EXPENSES--The Partnership bears all operating expenses related to its
trading activities, to a maximum of 1/4 of 1% annually of the Partnership's
average month-end Net Assets. These include filing fees, clerical,
administrative, auditing, accounting, mailing, printing and other incidental
operating expenses as permitted by the Limited Partnership Agreement. In
addition, the Partnership incurs a monthly management fee and may incur an
incentive fee. Prior to August 1, 1996, pursuant to a Letter of Credit and
Reimbursement Agreement with JWH and Citibank, the Partnership paid to Citibank
a quarterly Letter of Credit fee equal to 1% of the Partnerships's "New
Appreciation," as defined in the Letter of Credit and Reimbursement Agreement,
of the Partnership's Net Assets as of the end of each calendar quarter. Such
fee was accrued in each month in which "New Appreciation" occurred. In those
months in which "New Appreciation" was negative, previous accruals, if any,
during the quarter were reduced. Demeter and/or DWR bear all other operating
expenses, including expenses which would be incurred if the Partnership were
required to register as an investment company.

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 the last day that is six months
after the closing at which a person becomes a limited partner, upon five
business days advance notice by redemption form to Demeter. Thereafter, Units
may be redeemed as of the end of any month upon five business days advance
notice by redemption form to Demeter. However, any Units redeemed at or prior
to the end of the twelfth, eighteenth or twenty-fourth full month following the
closing at which such person first becomes a limited partner, is subject to a
redemption charge equal to 3%, 2% or 1%, respectively, of the Net Asset Value
per Unit on the date of such redemption. Limited Partners who obtain their
units via an exchange from another DWR sponsored commodity pool are not subject
to the six months holding period or the redemption charges.

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

INCOME TAXES--No provision for income taxes has been made in the accompanying
financial statements, as partners are individually responsible for reporting
income or loss based upon their respective share of the Partnership'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.

2. RELATED PARTY TRANSACTIONS

The Partnership's cash is on deposit with DWR and Carr in commodity trading
accounts to meet margin requirements as needed. DWR pays interest on these
funds as described in Note 1. Under its Customer Agreement with DWR, the
Partnership pays DWR brokerage commissions as described in Note 1.

3. TRADING MANAGER

Compensation to JWH consists of a management fee and an incentive fee as
follows:

MANAGEMENT FEE--The Partnership pays a monthly management fee equal to 1/3 of
1% per month of the Partnership's adjusted Net Assets, as defined in the


DEAN WITTER PORTFOLIO STRATEGY FUND L.P.
NOTES TO FINANCIAL STATEMENTS--(CONTINUED)

Limited Partnership Agreement, as of the last day of each month.

INCENTIVE FEE--The Partnership pays a quarterly incentive fee to JWH equal to
15% of the Partnership's "New Appreciation", as defined in the Limited
Partnership Agreement, of the Partnership's Net Assets as of the end of each
calendar quarter. 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 are reduced. In those
instances, in which a Limited Partner redeems an investment, the incentive fee
(if earned through a redemption date) is paid to JWH on those redemptions in
the month of such redemptions.

4. FINANCIAL INSTRUMENTS

The Partnership trades futures and forward contracts in interest rates, stock
indices, commodities, currencies, petroleum and precious metals. 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. At December 31, 1997 and 1996 open contracts were:


CONTRACT OR NOTIONAL AMOUNT

EXCHANGE-TRADED CONTRACTS
Financial Futures:
Commitments to Purchase 231,632,000 65,197,000
Commitments to Sell 83,000,000 70,325,000
Commodity Futures:
Commitments to Purchase 20,890,000 5,005,000

Commitments to Purchase 78,711,000 89,146,000
Commitments to Sell 126,515,000 38,531,000


A portion of the amounts indicated as off-balance-sheet risk in forward
currency contracts is due to offsetting forward commitments to purchase and to
sell the same currency on the same date in the future. These commitments are
economically offsetting, but are not offset in the forward market until the
settlement date.


DEAN WITTER PORTFOLIO STRATEGY FUND L.P.
NOTES TO FINANCIAL STATEMENTS--(CONTINUED)

The unrealized gains on open contracts are reported as a component of "Equity
in Commodity futures trading accounts" on the Statements of Financial Condition
and totaled $9,771,078 and $3,053,880 at December 31, 1997 and 1996,
respectively.

Of the $9,771,078 net unrealized gain on open contracts at December 31, 1997,
$9,025,112 related to exchange-traded futures contracts and $745,966 related to
off-exchange-traded forward currency contracts.

Of the $3,053,880 net unrealized gain on open contracts at December 31, 1996,
$3,465,469 related to exchange-traded futures contracts and $(411,589) related
to off-exchange-traded forward currency contracts.

Exchange-traded futures contracts held by the Partnership at December 31, 1997
and 1996 mature through December 1998 and December 1997, respectively. Off-
exchange-traded forward currency contracts held by the Partnership at December
31, 1997 and 1996 mature through March 1998 and March 1997, respectively.

The contract amounts in the above table represent the Partnership's extent of
involvement in the particular class of financial instrument, but not the credit
risk associated with counterparty nonperformance. The credit risk associated
with these instruments is limited to the amounts reflected in the Partnership's
Statements of Financial Condition.

The Partnership also has credit risk because either DWR or Carr acts as the
futures commission merchant or the counterparty, with respect to the
Partnerships' assets. Exchange-traded futures contracts are marked to market on
a daily basis, with variations in value settled on a daily basis. DWR and Carr,
as the futures commission merchants 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 gains on all open futures contracts, which funds totaled
$134,305,522 and $91,312,827 at December 31, 1997 and 1996, respectively. With
respect to the Partnership's off-exchange-traded forward currency contracts,
there are no daily settlements of variations in value nor is there any
requirement that an amount equal to the net unrealized gains on open forward


DEAN WITTER PORTFOLIO STRATEGY FUND L.P.
NOTES TO FINANCIAL STATEMENTS--(CONTINUED)

contracts be segregated. With respect to those off-exchange-traded forward
currency contracts, the Partnership is at risk to the ability of Carr, the sole
counterparty on all of such contracts, to perform. Carr's parent, Credit
Agricole Indosuez, has guaranteed Carr's obligations to the Partnership.

For the years ended December 31, 1997 and 1996, the average fair value of
financial instruments held for trading purposes was as follows:

5. LEGAL MATTERS

On September 6, 10, and 20, 1996, and on March 13, 1997, similar 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,
Dean Witter Futures and Currency Management Inc., MSDWD (all such parties
referred to hereafter as the "Dean Witter Parties"), the Partnership (under its
original name), certain other limited partnership commodity pools of which
Demeter is the general partner, and certain trading advisors (including JWH) 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.

NOTES TO FINANCIAL STATEMENTS--(CONCLUDED)

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 Dean Witter Parties and certain trading advisors (including JWH) 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. 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. The
complaints seek unspecified amounts of compensatory and punitive damages and
other relief. It is possible that additional similar actions may be filed and
that, in the course of these actions, other parties could be added as
defendants. The Dean Witter Parties believe that they and the Partnership have
strong defenses to, and they will vigorously contest, the actions. Although the
ultimate outcome of legal proceedings cannot be predicted with certainty, it is
the opinion of management of the Dean Witter Parties that the resolution of the
actions will not have a material adverse effect on the financial condition or
the results of operations of any of the Dean Witter Parties or the Partnership.
