Item 1. Business

General

   World Monitor Trust II (the 'Trust') is a business trust organized under the
laws of Delaware on April 22, 1999. As of December 31, 1999, the Trust had not
yet commenced trading operations. The Trust consists of three separate and
distinct series ('Series'): Series D, E and F (each a 'Registrant' and
collectively, the 'Registrants'). The assets of each Series are segregated from
the other Series, separately valued and independently managed. Each Series was
formed to engage in the speculative trading of a diversified portfolio of
futures, forward and options contracts and may, from time to time, engage in
cash and spot transactions. The trustee of the Registrants is Wilmington Trust
Company. The Registrants' fiscal year for book and tax purposes ends on December
31.

   Up to $50,000,000 of beneficial interests in each Series ('Interests') are
being offered (totalling $150,000,000) unless the managing owner, in its sole
discretion, exercises its over-subscription option to offer additional interests
('Subscription Maximum'). Interests are being offered to investors who meet
certain established suitability standards, with a minimum initial subscription
of $5,000 ($2,000 for an individual retirement account ('IRA')), although the
minimum purchase for any single Series is $1,000.

   Initially, the Interests for each Series were being offered for a period of
up to 180 days after the date of the Prospectus ('Initial Offering Period'). The
price per Interest during the Initial Offering Period was $100. Each Series
could commence operations at any time if the minimum amount of Interests were
sold before the Initial Offering Period expired ('Subscription Minimum'). The
Subscription Minimum is $5,000,000 for each Series. During March 2000, the
Subscription Minimum for each Series was reached and as a result, trading began
for Series D and Series F on March 13, 2000 and March 1, 2000, respectively. It
is anticipated that Series E will begin trading shortly. Thereafter, or until
the Subscription Maximum for each Series is reached, each Series' Interests will
continue to be offered on a weekly basis at the then current net asset value per
Interest ('Continuous Offering Period').

   The Registrants are engaged solely in the business of commodity futures and
forward trading; therefore, presentation of industry segment information is not
available.

Managing Owner and its Affiliates

   The managing owner of the Registrants is Prudential Securities Futures
Management Inc. (the 'Managing Owner'), a wholly owned subsidiary of Prudential
Securities Incorporated ('PSI') which, in turn, is a wholly owned subsidiary of
Prudential Securities Group Inc. PSI is the selling agent for the Registrants as
well as the commodity broker of the Registrants. The Managing Owner is required
to maintain at least a 1% interest in the capital, profits and losses of each
Series so long as it is acting as the Managing Owner, and it will make such
contributions (and in return will receive such general interests) as are
necessary to effect this requirement.

The Trading Advisors

   Each Series has its own professional commodity trading advisor that makes
that Series' trading decisions. The Managing Owner, on behalf of the Trust,
entered into advisory agreements with Bridgewater Associates, Inc., Graham
Capital Management, L.P. and Campbell & Company, Inc. (each a 'Trading Advisor')
to make the trading decisions for Series D, E and F, respectively. Each advisory
agreement may be terminated at the discretion of the Managing Owner. It is
currently contemplated that each Series' Trading Advisor will be allocated one
hundred percent of the capital raised for that Series during the Initial and
Continuous Offering Periods.

Competition

   The Managing Owner and its affiliates have formed, and may continue to form,
various entities to engage in the speculative trading of futures, forward and
options contracts which have certain of the same investment policies as the
Registrants.

                                       3

<PAGE>
   The Trust is an open-end series of funds which will solicit the sale of
additional Interests on a weekly basis until the Subscription Maximum for each
Series is reached. As such, each Registrant may compete with other entities to
attract new participants. In addition, to the extent that a Trading Advisor
recommends similar or identical trades to a Registrant and other accounts which
it manages, that Registrant may compete with those accounts for the execution of
the same or similar trades.

Employees

   The Registrants have no employees. Management and administrative services for
each Registrant are performed by the Managing Owner and its affiliates pursuant
to the First Amended and Restated Declaration of Trust and Trust Agreement
('Trust Agreement') as further discussed in Notes A, C and D to the Registrants'
annual report for the period ended December 31, 1999 ('Registrants' 1999 Annual
Report') which is filed as an exhibit hereto.

Item 2. Properties

   The Registrants do not own or lease any property.

Item 3. Legal Proceedings

   There are no material legal proceedings pending by or against the Registrants
or the Managing Owner.

Item 4. Submission of Matters to a Vote of Interest Holders

   None

                                    PART II

Item 5. Market for the Registrant's Interests and Related Interest Holder
        Matters

   Information with respect to the offering of Interests is incorporated by
reference to Note A to the Registrants' 1999 Annual Report, which is filed as an
exhibit hereto.

   A significant secondary market for the Interests is not expected to develop
in the future. There are also certain restrictions set forth in the Trust
Agreement limiting the ability of an Interest holder to transfer Interests.
However, Interests may be redeemed on a weekly basis, but are subject to a
redemption fee if effected within one year of the effective date of purchase.
Additionally, Interests owned in one Series may be exchanged, without any
charge, for Interests of one or more other Series on a weekly basis for as long
as Interests in those Series are being offered to the public. Exchanges and
redemptions are calculated based on the applicable Series' then current net
asset value per Interest as of the close of business on the Friday immediately
preceding the week in which the exchange or redemption request is effected.

Item 6. Selected Financial Data

   As of December 31, 1999, the Registrants had not yet commenced operations.
The Managing Owner had contributed $1,000 to each Series and in return the
Managing Owner received 10 general interests in each Series.

Item 7. Management's Discussion and Analysis of Financial Condition and Results
        of Operations

   This information is incorporated by reference to page 8 of the Registrants'
1999 Annual Report which is filed as an exhibit hereto.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

   Information regarding quantitative and qualitative disclosures about market
risk is not required pursuant to Item 305(e) of Regulation S-K.

Item 8. Financial Statements and Supplementary Data

   The financial statements are incorporated by reference to pages 2 through 6
of the Registrants' 1999 Annual Report which is filed as an exhibit hereto.

                                       4

   Supplementary data specified by Item 302 of Regulation S-K (selected
quarterly financial data) is not applicable.

Item 9. Changes in and Disagreements with Accountants on Accounting and
        Financial Disclosure

   None

                                    PART III

Item 10. Directors and Executive Officers of the Registrant

   There are no directors or executive officers of the Registrants. The
Registrants are managed by the Managing Owner.

   The Managing Owner's directors and executive officers and any person holding
more than ten percent of each Registrant's Interests ('Ten Percent Owners') are
required to report their initial ownership of such Interests and any subsequent
changes in that ownership to the Securities and Exchange Commission on Forms 3,
4 or 5. Such executive officers, directors and Ten Percent Owners are required
by Securities and Exchange Commission regulations to furnish the Registrant with
copies of all Forms 3, 4 or 5 they file. All of these filing requirements were
satisfied on a timely basis. In making these disclosures, the Registrants have
relied solely on written representations of the Managing Owner's directors and
executive officers and Ten Percent Owners or copies of the reports that they
have filed with the Securities and Exchange Commission during and with respect
to its most recent fiscal year.

   The directors and executive officers of Prudential Securities Futures
