                         WORLD MONITOR TRUST--SERIES B
                          (a Delaware Business Trust)
                         NOTES TO FINANCIAL STATEMENTS
                                 June 27, 2003
                                  (Unaudited)

A. General

   These financial statements have been prepared without audit. In the opinion
of Prudential Securities Futures Management Inc. (the 'Managing Owner'), the
financial statements contain all adjustments (consisting of only normal
recurring adjustments) necessary to state fairly the financial position of World
Monitor Trust--Series B ('Series B') as of June 27, 2003 and December 31, 2002
and the results of its operations for the periods from January 1, 2003 to June
27, 2003 ('Year-To-Date 2003'), January 1, 2002 to June 28, 2002 ('Year-To-Date
2002'), March 29, 2003 to June 27, 2003 ('Second Quarter 2003') and March 30,
2002 to June 28, 2002 ('Second Quarter 2002'). However, the operating results
for the interim periods may not be indicative of the results expected for a full
year.

   Certain information and footnote disclosures normally included in annual
financial statements prepared in accordance with accounting principles generally
accepted in the United States of America have been omitted. It is suggested that
these financial statements be read in conjunction with the financial statements
and notes thereto included in Series B's Annual Report on Form 10-K filed with
the Securities and Exchange Commission for the year ended December 31, 2002.

   In February 2003, Prudential Financial, Inc. ('Prudential') and Wachovia
Corp. ('Wachovia') announced an agreement to combine each company's respective
retail securities brokerage and clearing operations within a new firm, which
will be headquartered in Richmond, Virginia. Under the agreement, Prudential
will have a 38% ownership interest in the new firm and Wachovia will own 62%.
The transaction, which includes the securities brokerage, securities clearing,
and debt capital markets operations of Prudential Securities Incorporated
('PSI'), but does not include the equity sales, trading and research operations
or commodity brokerage and derivative operations of PSI (which were renamed
Prudential Equity Group, Inc. upon closing), closed July 1, 2003. The Managing
Owner, as well as the commodity broker, will continue to be indirect wholly
owned subsidiaries of Prudential.

   The Managing Owner suspended the offering of Interests in Series B and World
Monitor Trust--Series C ('Series C') upon the expiration of selling
registrations, which expired by April 30, 2002.

B. Related Parties

   The Managing Owner of Series B is a wholly-owned subsidiary of Prudential
Equity Group, Inc. ('PEG'), which, in turn, is an indirect wholly-owned
subsidiary of Prudential Financial, Inc. The Managing Owner or its affiliates
perform services for Series B which include, but are not limited to: brokerage
services; accounting and financial management; registrar, transfer and
assignment functions; investor communications; printing and other administrative
services. Except for costs related to brokerage services, PEG or its affiliates
pay all costs of these services in addition to Series B's routine operational,
administrative, legal and auditing costs. Additionally, PEG or its affiliates
paid the costs associated with offering Series B's Interests.

   The costs charged to Series B for brokerage services for Year-To-Date 2003,
Year-To-Date 2002, Second Quarter 2003 and Second Quarter 2002 were $371,164,
$382,493, $190,303 and $190,435, respectively.

   All of the proceeds of the offering of Series B were received in the name of
Series B and were deposited in trading or cash accounts at PEG, Series B's
commodity broker. Series B's assets are maintained with PEG for margin purposes.
PEG credits Series B monthly with 100% of the interest it earns on the average
net assets in Series B's accounts.

   Series B, acting through its trading advisor, may execute over-the-counter,
spot, forward and/or option foreign exchange transactions with PEG. PEG then
engages in back-to-back trading with an affiliate, Prudential-Bache Global
Markets Inc. ('PBGM'). PBGM attempts to earn a profit on such transactions. PBGM
keeps its prices on foreign currency competitive with other interbank currency
trading desks. All over-the-counter currency transactions are conducted between
PEG and Series B pursuant to a line of credit. PEG may require that collateral
be posted against the marked-to-market positions of Series B.

C. Derivative Instruments and Associated Risks

   Series B is exposed to various types of risk associated with the derivative
instruments and related markets in which it invests. These risks include, but
are not limited to, risk of loss from fluctuations in the value of derivative
instruments held (market risk) and the inability of counterparties to perform
under the terms of Series B's investment activities (credit risk).

Market risk

   Trading in futures and forward contracts (including foreign exchange)
involves entering into contractual commitments to purchase or sell a particular
commodity at a specified date and price. The gross or face amount of the
contracts, which is typically many times that of Series B's net assets being
traded, significantly exceeds Series B's future cash requirements since Series B
intends to close out its open positions prior to settlement. As a result, Series
B is generally subject only to the risk of loss arising from the change in the
value of the contracts. As such, Series B considers the 'fair value' of its
derivative instruments to be the net unrealized gain or loss on the contracts.
The market risk associated with Series B's commitments to purchase commodities
is limited to the gross or face amount of the contracts held. However, when
Series B enters into a contractual commitment to sell commodities, it must make
delivery of the underlying commodity at the contract price and then repurchase
the contract at prevailing market prices or settle in cash. Since the repurchase
price to which a commodity can rise is unlimited, entering into commitments to
sell commodities exposes Series B to unlimited risk.

   Market risk is influenced by a wide variety of factors including government
programs and policies, political and economic events, the level and volatility
of interest rates, foreign currency exchange rates, the diversification effects
among the derivative instruments Series B holds and the liquidity and inherent
volatility of the markets in which Series B trades.

Credit risk

   When entering into futures or forward contracts, Series B is exposed to
credit risk that the counterparty to the contract will not meet its obligations.
The counterparty for futures contracts traded on United States and most foreign
futures exchanges is the clearinghouse associated with the particular exchange.
In general, clearinghouses are backed by their corporate members who are
required to share any financial burden resulting from the nonperformance by one
of their members and, as such, should significantly reduce this credit risk. In
cases where the clearinghouse is not backed by the clearing members (i.e., some
foreign exchanges), it is normally backed by a consortium of banks or other
financial institutions. On the other hand, there is concentration risk on
forward transactions entered into by Series B as PEG, Series B's commodity
broker, is the sole counterparty. Series B has entered into a master netting
agreement with PEG and, as a result, when applicable, presents unrealized gains
and losses on open forward positions as a net amount in the statements of
financial condition. The amount at risk associated with counterparty
nonperformance of all of Series B's contracts is the net unrealized gain
included in the statements of financial condition; however, counterparty
nonperformance on only certain of Series B's contracts may result in greater
loss than nonperformance on all of Series B's contracts. There can be no
assurance that any counterparty, clearing member or clearinghouse will meet its
obligations to Series B.

   The Managing Owner attempts to minimize both credit and market risks by
requiring Series B and its trading advisor to abide by various trading
limitations and policies. The Managing Owner monitors compliance with these
trading limitations and policies which include, but are not limited to,
executing and clearing all trades with creditworthy counterparties; limiting the
amount of margin or premium required for any one commodity or all commodities
combined; and generally limiting transactions to contracts which are traded in
sufficient volume to permit the taking and liquidating of positions.
Additionally, pursuant to the advisory agreement among Series B, the Managing
Owner and the trading advisor, Series B shall automatically terminate the
trading advisor if the net asset value allocated to the trading advisor declines
by 33 1/3% from the value at the beginning of any year or since the commencement
of trading activities. Furthermore, the Second Amended and Restated Declaration
of Trust and Trust Agreement provides that Series B will liquidate its
positions, and eventually dissolve, if Series B experiences a decline in the net
asset value of 50% from the value at the beginning of any year or since the
commencement of trading activities. In each case, the decline in net asset value
is after giving effect for distributions, contributions and redemptions. The
Managing Owner may impose additional restrictions (through modifications of
trading limitations and policies) upon the trading activities of the trading
advisor as it, in good faith, deems to be in the best interests of Series B.

   PEG, when acting as Series B's futures commission merchant in accepting
orders for the purchase or sale of domestic futures contracts, is required by
Commodity Futures Trading Commission ('CFTC') regulations to separately account
for and segregate as belonging to Series B all assets of Series B relating to
domestic futures trading and is not permitted to commingle such assets with
other assets of PEG. At June 27, 2003, such segregated assets totalled
$1,360,335. Part 30.7 of the CFTC regulations also requires PEG to secure assets
of Series B related to foreign futures trading which totalled $8,326,809 at June
27, 2003. There are no segregation requirements for assets related to forward
trading.

   As of June 27, 2003, all of Series B's open futures and forward contracts
mature within six months.

                         WORLD MONITOR TRUST--SERIES B
                          (a Delaware Business Trust)
           ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS

Liquidity and Capital Resources

   Series B commenced operations on June 10, 1998 with gross proceeds of
$5,709,093 allocated to commodities trading. Additional contributions raised
through the continuous offering for the period from June 10, 1998 (commencement
of operations) to April 30, 2002 resulted in additional gross proceeds to Series
B of $24,385,015. The Managing Owner suspended the offering of Interests in
Series B and Series C and allowed all selling registrations to expire by April
30, 2002. As such, Interests owned in one series of World Monitor Trust may no
longer be exchanged for the Interests of one or more other Series.

   Interests in Series B may be redeemed on a weekly basis, but are subject to a
redemption fee if transacted within one year of the effective date of purchase.
Redemptions of limited interests for Year-To-Date 2003, Second Quarter 2003 and
for the period from June 10, 1998 (commencement of operations) to June 27, 2003
were $715,712, $386,379 and $22,063,391, respectively. While there were no
redemptions of general interests during the First Quarter of 2003, redemptions
of general interests for Year-To-Date 2003 and the period from June 10, 1998
(commencement of operations) to June 27, 2003 totalled $18,845 and $207,046,
respectively. Future redemptions will impact the amount of funds available for
investment in commodity contracts in subsequent periods.

   At June 27, 2003, 100% of Series B's net assets were allocated to commodities
trading. A significant portion of the net assets was held in cash which is used
as margin for Series B's trading in commodities. Inasmuch as the sole business
of Series B is to trade in commodities, Series B continues to own such liquid
assets to be used as margin. PEG credits Series B monthly with 100% of the
interest it earns on the average net assets in Series B's accounts.

   The commodities contracts are subject to periods of illiquidity because of
market conditions, regulatory considerations and other reasons. For example,
commodity exchanges limit fluctuations in certain commodity futures contract
prices during a single day by regulations referred to as 'daily limits.' During
a single day, no trades may be executed at prices beyond the daily limit. Once
the price of 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 Series B from promptly liquidating its commodity
futures positions.

   Since Series B's business is to trade futures and forward contracts, its
capital is at risk due to changes in the value of these contracts (market risk)
or the inability of counterparties to perform under the terms of the contracts
(credit risk). Series B's exposure to market risk is influenced by a number of
factors including the volatility of interest rates and foreign currency exchange
rates, the liquidity of the markets in which the contracts are traded and the
relationships among the contracts held. The inherent uncertainty of Series B's
speculative trading as well as the development of drastic market occurrences
could result in monthly losses considerably beyond Series B's experience to date
and could ultimately lead to a loss of all or substantially all of investors'
capital. The Managing Owner attempts to minimize these risks by requiring Series
B and its trading advisor to abide by various trading limitations and policies,
which include limiting margin amounts, trading only in liquid markets and
permitting the use of stop loss provisions. See Note C to the financial
statements for a further discussion on the credit and market risks associated
with Series B's futures and forward contracts.

   Series B does not have, nor does it expect to have, any capital assets.

   Series B's trading gains before commissions were $1,425,000 and $580,000
during Year-To-Date 2003 and Second Quarter 2003, respectively, compared to
$1,029,000 and $1,097,000 for the corresponding periods in the prior year. Due
to the nature of Series B's trading activities, a period to period comparison of
its trading results is not meaningful. However, a detailed discussion of Series
B's Second Quarter 2003 trading results is presented below.

Quarterly Market Overview

   In the U.S., the beginning of the second quarter of 2003 saw few signs of
relief from a sluggish economy with a growth rate of 2.4 percent. Nominal GDP
continued to trend downward in hand with falling consumer and producer prices
and interest rates. Concerns about the slump in American telecom and internet
industries, accounting fraud and the largest budget deficit the U.S. has ever
faced have hampered investments in the U.S. Despite resolution to the war in
Iraq, consumer and business confidence remained tepid. Companies desiring to
improve profits remained unwilling to make big capital spending commitments or
increase their workforces and inventories. Orders to U.S. factories for
big-ticket items and production figures fell in April. In June, the unemployment
rate jumped to a nine-year high of 6.4 percent. Payroll slashes in manufacturing
and information industries generated the greatest job losses. As companies
attempted to do more with leaner workforces, overall productivity rose and
provided support for household income. The rise in income, combined with low
interest rates, reduced taxes, and availability of substantial home equity
spurred gains in consumer spending and increased sales of new homes. Toward the
end of the quarter, manufacturing rose slightly, but still indicated that the
sector shrank for the fourth straight month. Meanwhile, new orders for durable
goods, machinery, automobiles, electrical equipment, home supplies and computers
increased, reversing previous downward trends.

   Global economies remained weak in the second quarter of 2003 and were further
hampered by the decline of the U.S. dollar which made overseas goods more
expensive, thus, curtailing demand. In May, Germany, Italy and the Netherlands
reported an unexpected contraction in their economies during the first three
months of the year with Germany and Netherlands experiencing a second quarter of
negative growth. The European Union stated that overall economic growth had
stalled and consequently, applied pressure on the central banks to ease interest
rates. Business investment dropped sharply while domestic demand remained bleak.
The Japanese economy continued to stumble as other Asian economies began to
recover from the effects of the SARS outbreak. Furthermore, fears of deflation
loomed over already troubled global economies.

   Indices: Despite economic data indicating the worst is not yet over, global
equity markets surged in the second quarter of 2003. Spurred by the easing of
geopolitical tensions, massive short covering, excess liquidity, some positive
first quarter earnings reports, and optimism that economic recovery is near,
investors flocked toward equities. A rally in Japanese stocks was fueled
primarily by foreign mutual funds, hedge funds and other non-Japanese
institutional investors who invested more than ten times as much as local
investors in June. The Japanese Nikkei, London FTSE, Dow Jones Industrial
Average, NASDAQ and S&P 500 all ended the quarter higher.

   Interest rates: Fixed income markets in May witnessed a drop in interest
rates of developed countries due to the U.S. Federal Reserve (the 'Fed')
deflation talk as well as institutions and hedge funds borrowing to purchase
longer maturities, possible Fed purchases of longer maturities, hedging by
mortgage investors as rates fell, and central banks buying dollars and investing
in Treasuries. The decline in interest rates led to gains in German, Japanese,
U.S. Treasury and Eurodollar bond prices. In June, the market reacted with
disappointment to the Fed's quarter-point cut in short-term interest rates and
as a result, intermediate and long-term rates rose. Investors in Japan moved
capital into the equity markets at the expense of U.S. Treasury and Japanese
bonds. Concern about deteriorating public finances in most large economies and a
renewed interest in equities in hopes of an economic recovery resulted in
falling bond prices through the quarter and the subsequent rising of long-term
rates.

   Currencies: In the foreign exchange markets, the U.S. dollar moved sharply
lower against most major currencies during the quarter. Investors shifted their
focus from the war in Iraq to concerns about U.S. economic health with its
widening current account deficit and lower relative interest rate resulting in
the dollar's three-year low against the Canadian and Australian dollar and
four-year low against the Euro. The reversal of the U.S.'s strong dollar policy
by Treasury Secretary Snow led to a further sell off of the greenback leading to
a 4.5-year low against the Swiss franc.

   Energies: Energy price declines began in March and continued as the war in
Iraq became inevitable. Because supplies were secured and unthreatened by the
war, the prices of crude oil, unleaded gasoline and London gas oil were down in
April of 2003. Natural gas prices were largely unaffected by events in the
Middle East, Nigeria and Venezuela. In order to stave off the declining prices
and correct an oversupply as crude demand reached a seasonal low, OPEC members
agreed to cut current output by seven percent in April. Toward the end of the
quarter, energy prices, in general, were higher due to Nigeria's general
worker's strike, low U.S. oil inventory levels and expectations of U.S. economic
growth.

Quarterly Performance of Series B

   The following is a summary of performance for the major sectors in which
Series B traded:

   Indices (+): Overall long positions in the NASDAQ, S&P 500 and German DAX
indices led to net gains as global equity markets rose throughout the quarter.

   Interest rates (+): Weak global economies, fears of deflation and renewed
interest in equities resulted in falling global bond prices. Short U.S. Treasury
and European bond positions led to net gains.

   Currencies (+): The U.S. dollar fell against many foreign currencies amid
concerns of a weak U.S. economy. Australian dollar and euro strengthened this
quarter resulting in net gains for long Australian dollar/U.S. dollar and
euro/U.S. dollar cross-rate positions.

   Energies (-): Nigeria's general worker's strike, low U.S. oil inventory
levels and expectation of economic growth led to rising energy prices toward the
end of the quarter. Short positions in natural gas and light crude oil resulted
in net losses.

   Metals (-): Declines in manufacturing resulted in falling base metal prices.
Long positions in aluminum and copper resulted in net losses.

   Slight decreases in interest income, commissions and management fees during
Year-To-Date 2003 as compared to Year-To-Date 2002 are primarily due to the
effect of redemptions during 2002 and 2003 on Series B's weekly net asset values
offset, significantly, by favorable trading performance during 2002 and 2003, as
further discussed below.

   Interest income is earned on the average net assets held at PEG and,
therefore, varies weekly according to interest rates, trading performance,
contributions and redemptions. Interest income decreased by approximately
$41,000 and $18,000 during Year-To-Date 2003 as compared to Year-To-Date 2002
and Second Quarter 2003 as compared to Second Quarter 2002, respectively, due to
the lower overall interest rates during 2003 versus 2002. Additionally, interest
income decreased during Year-To-Date 2003 as compared to Year-To-Date 2002 due
to the slight decrease in average net asset levels discussed above.

   Commissions are calculated on Series B's net asset value at the end of each
week and, therefore, vary according to weekly trading performance, contributions
and redemptions. Commissions decreased by approximately $11,000 during
Year-To-Date 2003 as compared to Year-To-Date 2002 due to the slight decrease in
average net asset levels as discussed above. Commissions during Second Quarter
2003 were comparable to the level incurred during Second Quarter 2002.

   All trading decisions for Series B are made by Eclipse Capital Management,
Inc. (the 'Trading Advisor'). Management fees are calculated on Series B's net
asset value at the end of each week and, therefore, are affected by weekly
trading performance, contributions and redemptions. Management fees decreased by
$3,000 during Year-To-Date 2003 as compared to Year-To-Date 2002 due to the
slight decrease in average net asset levels as discussed above. Management fees
during Second Quarter 2003 were comparable to the level incurred during Second
Quarter 2002.

   Incentive fees are based on the 'New High Net Trading Profits' generated by
the Trading Advisor, as defined in the advisory agreement among Series B, the
Managing Owner and the Trading Advisor. Incentive fees incurred during
Year-To-Date 2003 were $519. Series B did not incur an incentive fee during
Year-To-Date 2002 and the First Quarter of 2003.
