                                     PART I

Item 1:  Business
         --------

         (a)      General Development of Business:
                  -------------------------------

                  ML Principal Protection L.P. (the "Partnership" or the "Fund")
was organized under the Delaware Revised Uniform Limited Partnership Act on
January 3, 1994 and began trading operations on October 12, 1994. The Fund is a
multi-strategy, multi-market managed futures investment employing a range of
proprietary strategies diversified across major markets of the global economy --
financials, currencies, energy, metals and agriculture. The Fund trades in the
international futures and forward markets under the direction of multiple
independent professional advisors (the "Trading Advisors" or the "Advisors").
The Fund's objectives are achieving, through speculative trading, long-term
capital appreciation while controlling performance volatility.

                  Merrill Lynch Investment Partners Inc. (the "General Partner"
or "MLIP") acts as the general partner of the Partnership, and allocates the
Fund's assets among the Advisors, each of which trades independently of the
others. MLIP also determines what percentage of the Fund's assets to allocate to
trading and what percentage to hold in reserve. Merrill Lynch Futures Inc. (the
"Commodity Broker" or "MLF") is the Partnership's commodity broker. Merrill
Lynch Asset Management, L.P. ("MLAM") provides cash management services to the
Partnership, pursuant to guidelines established by MLIP for which MLAM assumes
no responsibility, investing Fund assets in securities issued by the U.S.
Government and its agencies ("Government Securities"). The General Partner is a
wholly-owned subsidiary of Merrill Lynch Group, Inc., which in turn is a
wholly-owned subsidiary of Merrill Lynch & Co., Inc. ("ML&Co."). The Commodity
Broker and MLAM are each an indirect wholly-owned subsidiary of ML&Co. (ML&Co.
and its affiliates are herein sometimes referred to as "Merrill Lynch.")

                  The Partnership does not trade directly but rather through a
subsidiary limited partnership, ML Principal Protection Trading L.P. (the
"Trading Partnership"), of which the General Partner is the general partner and
the Partnership the sole limited partner. See Item 1(c), "Narrative Description
of Business -- Two-Tier Structure of the Fund."

                  The Fund offers its units of limited partnership interest
("Units"), and receives and processes subscriptions, on a continuous basis
throughout each calendar quarter. Investors whose subscriptions are accepted at
any time during a calendar quarter are admitted to the Fund as Limited Partners
as of the beginning of the immediately following quarter, acquiring Units at
$100 per Unit. Investors' customer securities accounts are debited in the amount
of their subscriptions on settlement dates throughout each quarter shortly after
their subscriptions are accepted by MLIP. Subscription proceeds received during
a quarter are held in escrow pending investment in Units as of the beginning of
the following quarter. All interest earned on subscriptions while held in escrow
is paid to the investors on or about the date that Units are issued to them or
their subscription is rejected.

                  The Units sold, generally, at the beginning of each calendar
quarter, are sold in separate Series, each of which has its own Net Asset Value.
All Series trade pursuant to the same Advisor combination, but because they
begin trading at different times they have different Net Asset Values and may
have different percentages of their capital invested in the Trading Partnership.

                  Only the assets attributable to each Series of Units allocated
to the Trading Partnership are allocated to the Trading Advisors for management.
All outstanding Series of Units currently being issued initially allocate
approximately 85% of their total capital to the Trading Partnership, holding the
rest in reserve at the Partnership level.

                  As of December 31, 1998, the Partnership's capitalization was
$79,106,838, and the Net Asset value per Series A Unit (the initial Series of 
Units), originally $100 as of October 12, 1994, had risen to 134.74 (adding back
$19.00 in Distributions).

                  Through December 31, 1998, the highest month-end Net Asset
Value of a Series A Unit (the initial Series of Units) was $135.27
(adding back $15.50 in Distributions) (September 30, 1998) and the lowest
$101.04, (October 31, 1994).

                                       1
<PAGE>
 
                  The outstanding Series of Units are entitled to fixed-rate
annual distributions (which cannot be reduced prior to the first Principal
Assurance Date, as defined below, for such Series) and may also receive certain
discretionary distributions. No distributions are made on any Series of Units
sold after May 1, 1997.

                  The Fund is a "principal protected" commodity pool. ML&Co.
provides the guarantee described below under 1(c), "Narrative Description of
Business -- ML&Co.'s 'Principal Protection' Undertaking to the Fund" that all
Units of any given Series will have a Net Asset Value -- after payment of all
fixed-rate annual as well as discretionary distributions on such Units, in the
case of Units sold on or prior to May 1, 1997 -- of at least their initial $100
subscription price as of a specified date after their issuance (the "Principal
Assurance Date" for such Series, seven years after issuance for all outstanding
Series sold before May 1, 1997 and five years after issuance for all Series sold
thereafter ). This guarantee does not prevent substantial losses, but rather
serves only as a form of "stop loss," limiting the maximum loss which investors
who retain their Units until such Units' Principal Assurance Date can incur. In
order to protect ML&Co. from any liability under its guarantee, MLIP imposes
substantial opportunity costs on the Partnership by deleveraging its trading,
retaining a substantial portion of the Fund's assets in the Partnership rather
than investing such assets in the Trading Partnership for allocation to trading.
At such time, if any, as the Net Asset Value per Unit of a Series declined to
110% or less of the present value of $100, plus any fixed-rate annual
distributions due on such Series, discounted back from the Principal Assurance
Date, MLIP would terminate trading with respect to such Series altogether in
order to ensure that ML&Co. incurred no financial obligation to the Fund under
ML&Co.'s guarantee of the minimum Net Asset Value per Unit of such Series.

                  In the case of Units sold after May 1, 1997, the potential
opportunity costs of the Fund's "principal protection" are significantly
increased due to the fact that in the event that MLIP deleverages any Series of
such Units, it must deleverage all Series to the same degree. A Series could be
deleveraged as a result of losses which accrued subsequent to such Series having
recognized profits more than sufficient to offset such losses, but which were
earned before a more recent Series was issued and, consequently, were not
available to offset the same losses incurred by such Series. Conversely, losses
incurred before a particular Series is issued could indirectly cause a further
deleveraging of such Series' trading due to the effect of such losses on the
leverage which MLIP believes it is appropriate to use for an earlier-issued
Series.

         (b)      Financial Information about Segments:
                  ------------------------------------

                  The Partnership's business constitutes only one segment for
financial reporting purposes, i.e., a speculative "commodity pool." The
Partnership does not engage in sales of goods or services.

         (c)      Narrative Description of Business:
                  ---------------------------------

                  General

                  The Fund trades in the international futures, options on
futures, forwards and options on forward markets, with the objectives of
achieving long-term capital appreciation while controlling performance
volatility. The Fund's assets are allocated and reallocated by MLIP to the
trading management of independent trading advisors applying proprietary
strategies in numerous markets. MLIP may from time to time direct certain
individual Advisors to manage their Fund accounts as if they were managing up to
50% more equity than the actual capital allocated to them.

                  One of the objectives of the Fund is to provide
diversification for a limited portion of the risk segment of the Limited
Partners' portfolios. Commodity pool performance has historically often
demonstrated a low degree of performance correlation with traditional stock and
bond holdings. Since it began trading, the Fund's returns have, in fact,
frequently been significantly non-correlated (not, however, negatively
correlated) with the United States stock and bond markets.

                  ML&Co.'s "Principal Protection" Undertaking to the Fund

                  ML&Co. has agreed to contribute sufficient capital to the
Partnership so that it will have adequate funds, after adjusting for all
liabilities to third parties, that the Net Asset Value per Unit of each Series
will be no less than $100 as of the Principal Assurance Date for such Series
(after the payment of all distributions, if any, on Units of such Series). This
guarantee, which is effective with respect to any given Series as of the
Principal Assurance Date for 

                                       2
<PAGE>
 
such Series, is a guarantee only of a return of an investor's initial investment
(plus distributions, if any), not against the loss of the time value of such
investment or a guarantee of profit.


                  Operation of a Series after its Principal Assurance Date

                  MLIP may determine to dissolve a Series as of its Principal
Assurance Date, to extend the ML&Co. guarantee for a certain period of time
(resetting the minimum Net Asset Value per Unit of such Series guaranteed by
ML&Co.) or to continue to operate such Series without a "principal protection"
feature.

                  Two-Tier Structure of the Fund

                  The Fund does not trade in the futures and forward markets
directly, but rather through the Trading Partnership, of which the Fund is the
sole limited partner, and MLIP the sole general partner. The Fund's liability
for any trading losses is limited to the Fund's investment in the Trading
Partnership.

                  Use of Proceeds and Cash Management Income

                  Subscription Proceeds. MLIP pays from its own funds the
                  ---------------------
selling commissions relating to the sale of the Units. Accordingly, 100% of the
proceeds of Unit sales are received in cash by the Partnership and are available
for use in its speculative trading. In such trading, the Partnership's assets
are used as security for and to pay the Partnership's trading losses as well as
any expenses and redemptions. The primary use of the proceeds of the sale of the
Units is to permit the Advisors to trade on a speculative basis in a wide range
of different futures, options on futures, forwards and options on forward
markets on behalf of the Trading Partnership. While being used for this purpose,
the Partnership's assets are also generally available for cash management and to
earn interest, as more fully described below under "-- Available Assets."

                  Market Sectors. The Partnership trades in a diversified group
                  --------------
of markets under the direction of multiple independent Advisors. These Advisors
can, and do, from time to time materially alter the allocation of their overall
trading commitments among different market sectors. Except in the case of
certain trading programs which are purposefully limited in the markets which
they trade, there is essentially no restriction on the commodity interests which
may be traded by any Advisor or the rapidity with which an Advisor may alter its
market sector allocations.

                  The Fund's financial statements contain information relating
to the market sectors traded by the Fund. There can, however, be no assurance as
to which markets may be included in the Fund's portfolio or in which market
sectors the Fund's trading may be concentrated at any one time or over time.

                  Market Types. The Partnership trades on a variety of United
                  ------------
States and foreign futures exchanges. Substantially all of the Fund's
off-exchange trading takes places in the highly liquid, institutionally-based
currency forward markets.

                  Many of the Partnership's currency trades are executed in the
spot and forward foreign exchange markets (the "FX Markets") where there are no
direct execution costs. Instead, the participants, banks and dealers, including
Merrill Lynch International Bank ("MLIB"), in the FX Markets take a "spread"
between the prices at which they are prepared to buy and sell a particular
currency and such spreads are built into the pricing of the spot or forward
contracts with the Partnership. The General Partner anticipates that some of the
Partnership's foreign currency trades will be executed through MLIB, an
affiliate of the General Partner. MLIB has discontinued the operation of the
foreign exchange service desk, which included seeking multiple quotes from
counterparties unrelated to MLIB for a service fee and trade execution.

                  In its exchange of futures for physical ("EFP") trading, the
Partnership acquires cash currency positions through banks and dealers,
including Merrill Lynch. The Partnership pays a spread when it exchanges these
positions for futures. This spread reflects, in part, the different settlement
dates of the cash and the futures contracts, as well as prevailing interest
rates, but also includes a pricing spread in favor of the banks and dealers,
which may include a Merrill Lynch entity.

                                       3
<PAGE>
 
                  As in the case of its market sector allocations, the Fund's
commitments to different types of markets -- U.S. and non-U.S., regulated and
unregulated -- differ substantially from time to time as well as over time. The
Fund has no policy restricting its relative commitments to any of these
different types of markets.

                  The Fund's financial statements contain information relating
to the types of markets traded by the Fund. There can, however, be no assurance
as to in which markets the Fund may trade or as to how the Fund's trading may be
concentrated at any one time or over time.

                  Custody of Assets. All of the Fund's assets are currently held
                  -----------------
either in custodial or customer accounts at Merrill Lynch. Fund assets managed
by MLAM are generally held in custodial accounts at a major bank, separate from
all other Merrill Lynch or banking client assets. Assets held in customer
accounts are held at MLPF&S or MLF. These customer accounts are maintained in
the Fund's name, but the assets deposited by the Fund in such accounts are
commingled with those of other MLPF&S and MLF customers.

                  Available Assets. The Fund earns income, as described below,
                  ----------------
on its "Available Assets," which can be generally described as the cash actually
held by the Fund or invested in Treasury bills or Government Securities.
Available Assets are held primarily in U.S. dollars or in U.S. dollar
denominated Government Securities, and to a lesser extent in foreign currencies,
and are comprised of the following: (a) the Fund's assets managed by MLAM and
the Fund's cash balances held in the offset accounts (as described below)
which include "open trade equity" (unrealized gain and loss on open positions)
on United States futures contracts, which is paid into or out of the Fund's
account on a daily basis; (b) short-term Treasury bills purchased by the Fund;
and (c) the Fund's cash balance in foreign currencies derived from its trading
in non-U.S. dollar denominated futures and options contracts, which includes
open trade equity on those exchanges which settle gains and losses on open
positions in such contracts prior to closing out such positions. Available
Assets do not include, and the Fund does not earn interest on, the Fund's gains
or losses on its open forward, commodity option and certain foreign futures
positions since such gains and losses are not collected or paid until such
positions are closed out.

                  The Fund's Available Assets may be greater than, less than or
equal to the Fund's Net Asset Value (on which the redemption value of the Units
is based) primarily because Net Asset Value reflects all gains and losses on
open positions as well as accrued but unpaid expenses.

                  The Fund's U.S. Dollar Available Assets Managed by MLAM.
                  -------------------------------------------------------
Approximately 80% of the Fund's U.S. dollar Available Assets are managed
directly by MLAM, pursuant to guidelines established by MLIP for which MLAM
assumes no responsibility, in the Government Securities markets. MLIP's
objective in retaining MLAM to provide cash management services to the Fund is
to enhance the return earned on the Fund's U.S. dollar Available Assets managed
by MLAM to slightly above the 91-day Treasury bill rate. However, cash
management returns cannot be assured, and there may be losses of principal.

                  The Government Securities acquired by MLAM on behalf of the
Fund are maintained in a custodial account at Merrill Lynch and are specifically
traceable to the Fund. All income earned on such Government Securities inures to
the benefit of the Fund. All fees due to MLAM are paid at no additional cost to
the Fund.

                  Interest Earned on the Fund's U.S. Dollar Available Assets Not
                  --------------------------------------------------------------
Managed by MLAM. The following description relates to the approximately 20% of
---------------
the Fund's U.S. dollar Available Assets not managed by MLAM.

Offset Accounts and Short-Term Treasury Bills
---------------------------------------------

                  The Fund's U.S. dollar Available Assets not managed by MLAM
are held in cash in offset accounts and in short-term Treasury bills purchased
from dealers unaffiliated with Merrill Lynch. Offset accounts are non-interest
bearing demand deposit accounts maintained with banks unaffiliated with Merrill
Lynch. An integral feature of the offset arrangements is that the participating
banks specifically acknowledge that the offset accounts are MLF customer
accounts, not subject to any Merrill Lynch liability.

                  MLF credits the Fund, as of the end of each month, with
interest at the effective daily 91-day Treasury bill rate on the average daily
U.S. dollar Available Assets held in the offset accounts during such month. The
Fund receives all the interest paid on the short-term Treasury bills in which it
invests.

                                       4
<PAGE>
 
Possible Discontinuation of the Offset Accounts
-----------------------------------------------

                  The use of the offset account arrangements for the Fund's U.S.
dollar Available Assets not managed by MLAM may be discontinued by Merrill Lynch
whether or not Merrill Lynch otherwise continues to maintain its offset
arrangements. The offset arrangements are dependent on the banks' continued
willingness to make overnight credits available to Merrill Lynch, which, in
turn, is dependent on the credit standing of ML&Co. If Merrill Lynch were to
determine that the offset arrangements had ceased to be practicable (either
because ML&Co. credit lines at participating banks were exhausted or for any
other reason), Merrill Lynch would thereafter attempt to invest all of the
Fund's U.S. dollar Available Assets not managed by MLAM to the maximum
practicable extent in short-term Treasury bills. All interest earned on the U.S.
dollar Available Assets so invested would be paid to the Fund, but MLIP would
expect the amount of such interest to be less than that available to the Fund
under the offset account arrangements. The remaining U.S. dollar Available
Assets of the Fund not managed by MLAM would be kept in cash to meet variation
margin payments and pay expenses, but would not earn interest for the Fund.

Offset Account Benefit to Merrill Lynch
---------------------------------------

                  The banks at which the offset accounts are maintained make
available to Merrill Lynch interest-free overnight credits, loans or overdrafts
in the amount of the Fund's U.S. dollar Available Assets held in the offset
accounts, charging Merrill Lynch a small fee for this service. The economic
benefits derived by Merrill Lynch, net of the interest credits paid to the Fund
and the fee (of approximately 0.25% per annum) paid to the offset banks, from
the offset accounts have not exceeded 0.75% per annum of the Fund's average
daily U.S. dollar Available Assets held in the offset accounts. These benefits
to Merrill Lynch are in addition to the Brokerage Commissions and Administrative
Fees paid by the Fund to MLF and MLIP, respectively.

                  Interest Paid by Merrill Lynch on the Fund's Non-U.S. Dollar
                  ------------------------------------------------------------
Available Assets. Under the single currency margining system implemented for the
----------------
Fund, the Fund itself does not deposit foreign currencies to margin trading in
non-U.S. dollar denominated futures contracts and options, if any, MLF provides
the necessary margin, permitting the Fund to retain the monies which would
otherwise be required for such margin as part of the Fund's U.S. dollar
Available Assets. The Fund does not earn interest on foreign margin deposits
provided by MLF. The Fund does, however, earn interest on its non-U.S. dollar
Available Assets. Specifically, the Fund is credited by Merrill Lynch with
interest at the prevailing local short-term rate on realized and unrealized
gains on non-U.S. dollar denominated positions for such gains actually held in
cash by the Fund. Merrill Lynch charges the Fund Merrill Lynch's cost of
financing realized and unrealized losses on such positions.

                  The Fund holds foreign currency gains and finances foreign
currency losses on an interim basis until converted into U.S. dollars and either
paid into or out of the Fund's U.S. dollar Available Assets. Foreign currency
gains or losses on open positions are not converted into U.S. dollars until the
positions are closed. Assets of the Fund while held in foreign currencies are
subject to exchange-rate risk.

</TABLE>
                  The foregoing table does not reflect the bid-ask spreads paid
by the Fund on its forward trading, or the benefits which may be derived by
Merrill Lynch from the deposit of certain of the Fund's U.S.
dollar available assets in offset accounts.

                  The Fund's average month-end Net Assets during 1998, 1997 and
1996 equaled $95,777,172, $85,646,152 and $82,789,767, respectively.

                  During 1998, 1997 and 1996, the Fund earned $5,434,851,
$4,873,872 and $4,545,186 in interest income, or approximately 5.67%, 5.69% and
5.49% of the Fund's average month-end Net Assets.

                  Effective January 1, 1997, MLIP reduced the Fund's annual
Brokerage Commissions from 9.25% to 8.75% of trading assets (i.e., assets
committed to trading).

                  Effective October 1, 1998, MLIP reduced the Fund's annual
Brokerage Commission from 8.75% to 7.50% of trading assets.

                  Effective October 1, 1998, the Administrative Fee, while it
continues to be calculated at the rate of 0.25% per annum, is based on the
Fund's month-end total assets (prior to reduction for accrued expenses), not the
Fund's assets allocated to trading.

                                                     to 7.50% per annum (0.625 of 1% of the Fund's month-end traded assets).

                                                     During 1998, 1997 and 1996, the round-turn (each purchase and sale or sale and

Trading Advisors           Profit Shares              Prior to January 1, 1997, all Advisors received quarterly Profit Shares
                                                      ranging from 15% to 25% (depending on the Trading Advisor) of any New Trading

                                                      annual Profit Shares. Profit Shares are also paid upon the net reallocation of
                                                      assets away from an Advisor and the redemption of Units. New Trading Profit is

                  Regulation

                  The General Partner, the Trading Advisors and the Commodity
Broker are each subject to regulation by the Commodity Futures Trading
Commission (the "CFTC") and the National Futures Association. Other than in
respect of its periodic reporting requirements under the Securities Exchange Act
of 1934, and the registration of the Units for continuous public distribution
under the Securities Act of 1933, the Partnership itself is generally not
subject to regulation by the Securities and Exchange Commission. However, MLIP
itself is registered as an "investment adviser" under the Investment Advisers
Act of 1940.

                  (i) through (xii) -- not applicable.

                  (xiii)  The Partnership has no employees.

          (d)     Financial Information about Geographic Areas:
                  --------------------------------------------

                  The Trading Partnership trades, on a number of foreign
commodity exchanges. The Partnership does not engage in the sales of goods or
services.

Item 2:  Properties
         ----------

         Neither the Partnership nor the Trading Partnership use any physical
properties in the conduct of its business.

         The Partnership's and the Trading Partnership's only place of business
is the place of business of the General Partner (Merrill Lynch World
Headquarters, World Financial Center, South Tower, New York, New York, 10080).
The General Partner performs all administrative services for the Partnership and
the Trading Partnership from the General Partner's offices.

Item 3:  Legal Proceedings
         -----------------

                  ML&Co. -- the sole stockholder of Merrill Lynch Group, Inc.
(which is the sole stockholder of MLIP) -- as well as certain of its
subsidiaries and affiliates have been named as defendants in civil actions,
arbitration proceedings and claims arising out of their respective business
activities. Although the ultimate outcome of these 

                                       8
<PAGE>
 
actions cannot be predicted at this time and the results of legal proceedings
cannot be predicted with certainty, it is the opinion of management that the
result of these matters will not be materially adverse to the business
operations of financial condition of MLIP or the Fund.

                  MLIP itself has never been the subject of any material
litigation.

Item 4:  Submission of Matters to a Vote of Security Holders
         ---------------------------------------------------

                  The Partnership has never submitted any matters to a vote of
its Limited Partners.

Item 5:  Market for Registrant's Common Equity and Related Stockholder Matters
         ---------------------------------------------------------------------
Item 5(a)
---------

         (a)      Market Information:
                  ------------------

                  There is no established public trading market for the Units,
nor will one develop. Rather, Limited Partners may redeem Units as of the end of
each month at Net Asset Value, subject to certain early redemption charges.
Units redeemed prior to the Principal Assurance Date are not entitled to any
benefits under the Merrill Lynch & Co., Inc. guarantee.

         (b)      Holders:
                  -------

                  As of December 31, 1998, there were 4,114 holders of Units,
including the General Partner.

          (c)     Dividends:
                  ---------

                  For Series issued on or prior to May 1, 1997, the Partnership
makes annual fixed-rate distributions, payable irrespective of profitability, of
$3.50 per Unit. The General Partner may also make discretionary distributions of
up to 50% of any Distributable New Appreciation, as defined, recognized as of
each twelve-month anniversary of the issuance of each Series of Units, subject
to an annual limit of 4% of the Net Asset Value per Unit of each Series as of
the beginning of the preceding twelve-month period. Distributions, whether
fixed-rate or discretionary, do not reduce the $100 minimum Net Asset Value per
Unit assured to investors as of the Principal Assurance Date for their Series of
Units.

         (1) As of January 1, 1996, a portion of the Brokerage Commissions were
reclassified as Administrative Fees, at no additional cost to the Fund. Certain
amounts in prior periods have been reclassified to conform to the current period
presentation of the Administrative Fees.

         (2) MLIP is general partner of the Trading Partnership. Because the
Fund owns substantially all of the Trading Partnership, Trading Partnership
activities are referred to as Fund activities in this Report. The minority
interest represents MLIP's share, as general partner of the Trading Partnership,
of the Trading Partnership's profit or loss.

         (3) Balance Sheet Data is based on redemption values which differ
immaterially from Net Asset Values as determined under Generally Accepted
Accounting Principle ("GAAP") due to the treatment of organizational and initial

                  Rates of Return are presented on a composite, not a
Series-by-Series, basis.


                            -------------------------

                  All Units issued on or prior to May 1, 1997 commenced trading
with 60%, and Units issued after May 1, 1997 with 75%, of their assets allocated
to trading. Beginning May 1, 1998, all Units issued after May 1, 1997 have
allocated 85% of their assets to trading.

                            -------------------------

                  (1) Pursuant to applicable CFTC regulations, a "Multi-Advisor"
fund is defined as one that allocates no more than 25% of its trading assets to
any single manager. The Fund does not currently allocate more than 25% of its
trading assets to any single Advisor but may do so in the future; consequently,
it is referred to as a"Multi-Advisor; Selected Advisor" fund. Certain funds,
including funds sponsored by MLIP, are structured so as to guarantee to
investors that their investment will be worth no less than a specified amount
(typically, the initial purchase price) as of a date certain after the date of
investment. The CFTC refers to such funds as "principal protected." The ML&Co.
Guarantee and MLIP- related deleveraging of the Fund's trading provides the
"principal protection" feature of the Fund.

                  (2) Worst Monthly Drawdown represents the largest negative
Monthly Rate of Return experienced by the Fund; a drawdown is measured on the
basis of month-end Net Asset Value only, and does not reflect intra-month
figures.

         (3) Worst Peak-to-Valley Drawdown represents the greatest percentage
decline from a month-end cumulative Monthly Rate of Return without such
cumulative Monthly Rate of Return being equaled or exceeded as of a subsequent
month-end. For example, if the Monthly Rate of Return was (1)% in each of
January and February, 1% in March and (2)% in April, the Peak-to-Valley Drawdown
would still be continuing at the end of April in the amount of approximately
(3)%, whereas if the Monthly Rate of Return had been approximately 3% in March,
the Peak-to-Valley Drawdown would have ended as of the end of February at
approximately the (2)% level.

                  (4) Monthly Rate of Return is the net performance of the Fund
during the month of determination (including interest income and after all
expenses accrued or paid) divided by the total equity of the Fund as of the
beginning of such month.

         The Two-Tier Structure of the Fund

                  The Fund does not trade directly through opening managed
accounts with the Advisors, but rather through investing in the Trading
Partnership. The Trading Partnership, in turn, allocates its capital to the
Advisors. No series of Units can lose more in its trading than the amount which
such series has invested in the Trading Partnership.

                  Although different series of Units invest different
percentages of their overall capital in the Trading Partnership, all assets so
invested are 100% allocated to trading. All trading profits and losses are
shared pro rata among the different series based on their respective investments
in the Trading Partnership.

                  The use of the Trading Partnership by the Fund has no effect
on the leverage at which the different series of Units trade. The Fund trades
through investing in the Trading Partnership rather than directly, solely in
order to eliminate the highly unlikely risk that one series of Units might be
subject to paying trading debts attributable to another.

                  There is no benefit (or detriment) to investors from the
two-tier Fund/Trading Partnership structure other than permitting the Fund to
issue the series of Units at different times, which series, may, over time,
trade with different percentages of their capital allocated to trading.

Results of Operations

         Advisor Selections

                  The Fund's results of operations depend on MLIP's ability to
select Advisors and the Advisors' ability to trade profitably. MLIP's selection
procedures and trading leveraging analysis, as well as the Advisors' trading
methods, are confidential, so that substantially the only available information
relevant to the Fund's results of operations is its actual performance record to
date. Because of the speculative nature of its trading, the Fund's past
performance is not necessarily indicative of its future results.

                  MLIP has made and expects to continue making frequent changes
to both trading asset allocations among Advisors and Advisor combinations as
well as from time to time adjusting the percentage of the Fund's assets
committed to trading. All series of Units trade under the direction of the same
Advisor allocation and combination, as the same may be changed from time to time
by MLIP.

                  MLIP's decision to terminate or reallocate assets among
Advisors is based on a combination of numerous factors. Advisors are, in
general, terminated primarily for unsatisfactory performance, but other factors
-- for example, a change in MLIP's or an Advisor's market outlook, apparent
deviation from announced risk control policies, excessive turnover of positions,
changes in principals, commitment of resources to other business activities,
etc. -- may also have a role in the termination or reallocation decision. The
market judgment and experience of MLIP's principals is an important factor in
its asset allocation decisions.

                  MLIP has no timetable or schedule for making Advisor changes
or reallocations, and generally makes a medium- to long-term commitment to all
Advisors selected. There can be no assurance as to the frequency or number of
Advisor changes that may take place in the future, or as to how long any of the
current Advisors will continue to manage assets for the Fund.

General

                  A number of the Advisors are trend-following traders, whose
programs do not attempt to predict price movements. No fundamental economic
supply or demand analyses are used by these Advisors, and no macroeconomic
assessments of the relative strengths of different national economies or
economic sectors. Instead, the programs apply proprietary computer models to
analyzing past market data, and from this data alone attempt to determine
whether market prices are trending. These technical traders base their
strategies on the theory that market prices reflect the collective judgment of
numerous different traders and are, accordingly, the best and most efficient
indication of market movements. However, there are frequent periods during which
fundamental factors external to the market dominate prices.

                  If a trend-following Advisor's models identify a trend, they
signal positions which follow it. When these models identify the trend as having
ended or reversed, these positions are either closed out or reversed. Due to
their trend-following character, these Advisors' programs do not predict either
the commencement or the end of a price movement. Rather, their objective is to
identify a trend early enough to profit from it and detect its end or reversal
in time to close out the Fund's positions while retaining most of the profits
made from following the trend.

                  In analyzing the performance of trend-following programs,
economic conditions, political events, weather factors, etc., are not directly
relevant because only market data has any input into trading results.
Furthermore, there is no direct connection between particular market conditions
and price trends. There are so many influences on the markets that the same
general type of economic event may lead to a price trend in some cases but not
in others. The analysis is further complicated by the fact that the programs are
designed to recognize only certain types of trends and to apply only certain
criteria of when a trend has begun. Consequently, even though significant price
trends may occur, if these trends are not comprised of the type of intra-period
price movements which the programs are designed to identify, a trend-following
Advisor may miss the trend altogether.

                  In the case of the Advisors which implement strategies which
rely more on discretion and market judgment, it is not possible to predict, from
their performance during past market cycles, how they will respond to future
market events.

         Performance Summary

                  This performance summary is an outline description of how the
Fund performed in the past, not necessarily any indication of how it will
perform in the future. In addition, the general causes to which certain price
movements are attributed may or may not in fact have caused such movements, but
simply occurred at or about the same time.

                  The Advisors, as a group, are unlikely to be profitable in
markets in which such trends do not occur. Static or erratic prices are likely
to result in losses. Similarly, unexpected events (for example, a political
upheaval, natural disaster or governmental intervention) can lead to major
short-term losses as well as gains.

                  While there can be no assurance that any Advisor will be
profitable, under any given market condition, markets in which substantial and
sustained price movements occur typically offer the best profit potential for
the Fund.

                  Global interest rate markets provided the Fund with its most
profitable positions for the first quarter, particularly in European bonds where
an extended bond market rally continued despite an environment of robust growth
in the United States, Canada and the United Kingdom, as well as a strong pick-up
in growth in continental Europe. In the second quarter, swings in the U.S.
dollar and developments in Japan affected bond markets, causing the Fund's
interest rate trading to result in losses. This was turned around in the third
quarter, as markets worldwide were turned upside down and the Fund's
non-correlation with general equity and debt markets was strongly exhibited, and
trading was particularly profitable in positions in Eurodollars, German and
Japanese bonds, and U.S. Treasury notes and bonds. Global investors staged a
major flight to quality, resulting in a significant widening of credit spreads
on a global basis. In October, investors pushed the yields on U.S. Treasury
bonds to a 31-year low. The long bond yield fell about 75 basis points in 1998
as the world economy slowed more than expected, inflation continued to fall, the
anticipated small U.S. budget deficit turned into substantial surplus, and the
Fed lowered interest rates.

                  In currency markets, results early in the year were mixed,
although marginally profitable. During the second quarter, strong gains were
realized in positions in the Japanese yen, which weakened during June to an
eight-year low versus the U.S. dollar. Significant gains from Japanese yen
trading continued into the third quarter, and Japan's problems spread to other
sectors of the global economy, causing commodities prices to decline as demand
from the Asian economies weakened. Japan's deepening recession and credit crunch
continued through the fourth quarter, and the Fund achieved gains from long yen
positions.

                  Trading results in stock index markets were also mixed in
early 1998, despite a strong first-quarter performance by the U.S. equity market
as several consecutive weekly gains were recorded with most market averages
setting new highs. Second quarter results were profitable as the Asia-Pacific
region's equity markets weakened across the board. In particular, Hong Kong's
Hang Seng index trended downward during most of the second quarter and traded at
a three-year low. As U.S. equity markets declined in July and August, the Fund
profited from short positions in the S&P 500, most notably during August, when
the index dropped 14.5%. Volatility in September made for a difficult trading
environment in the stock index sector, and the Fund incurred modest losses,
although results remained profitable for the quarter and the year overall in
these markets.

                  In agricultural commodity markets, 1998 began with strong
gains as live cattle and hog prices trended downward throughout the first
quarter. In the second quarter, although the U.S. soybean crop got off to a good
start which contributed to higher yield expectations and a more burdensome
supply outlook, soybean prices traded in a volatile pattern. Sugar futures
maintained mostly a downtrend, as no major buyers emerged to support the market.
Similarly, coffee prices trended downward, as good weather conditions in Central
America and Mexico increased the prospects of more output from these countries.
The third quarter resulted in losses as the U.S. soybean crop increased relative
to the USDA's production estimate as a result of timely rains, which contributed
to lower prices. These losses continued into the fourth quarter as the Fund was
caught on the short side of the soybean complex, as the soybean supply surplus
became more manageable following the November 10th USDA reports, causing prices
to gain upward momentum.

                  Gold prices began the year drifting sideways, and continued to
weaken following news in the second quarter of a European Central Bank consensus
that ten to fifteen percent of reserves should be made up of gold bullion, which
was at the low end of expectations. Gold was unable to extend third quarter
rallies or to build any significant upside momentum, resulting in a trendless
environment. This was also the case in the fourth quarter, as gold's cost of

                                       17

production declined. Also, silver markets remained range-bound, while also
experiencing a significant selloff in November, and aluminum traded at its
lowest levels since 1994, with many aluminum smelters operating at a loss.

                  In energy markets, demand for crude oil in the Middle East was
affected by low oil prices early in the year, and trading resulted in losses.
Initially buoyed on concerns about a U.S.-led military strike against Iraq,
crude oil fell to a nine-year low, as the globally warm winter, the return of
Iraq as a producer and the Asian economic crisis added to OPEC's supply glut
problems. Despite production cuts initiated by OPEC at the end of March, world
oil supplies remained excessive and oil prices stood at relatively low levels
throughout the first half of 1998. Short heating oil positions in the third
quarter proved profitable for the Fund as the market for heating oil prices
dropped to its lowest level in more than a decade. In early December, oil and
natural gas prices dropped sharply, causing continued problems for many emerging
market countries that depend on commodity exports for economic growth and
government financing. These price pressures were mainly due to excessive supply
availability and near-term weather indications that inventories would remain at
more than adequate levels even in the event of a cold Northern Hemisphere
winter. Also, the December U.S. air attack on Iraq failed to cause any damage to
oil pumping and shipping operations, and oil prices fell over 10%.

                  In currency markets, the U.S. dollar rallied and started 1997
on a strong note, rising to a four-year high versus the Japanese yen and
two-and-a-half year highs versus the Deutsche mark and the Swiss franc. However,
the dollar underwent two significant corrections during the year. The first
correction occurred in the Spring against the Japanese yen, due to the G7
finance ministers' determination that a further dollar advance would be
counter-productive to their current goals. From August through mid-November, the
dollar corrected against the Eurocurrencies in advance of a well-advertised
tightening by the Bundesbank. By mid-December the dollar had bounced back to new
highs against the yen and was rallying against the mark.

                  Global interest rate markets began the year on a volatile
note, as investors evaluated economic data for signs of inflation. By the middle
of the year, economic data in key countries was positive indicating lower
inflation and igniting a worldwide rally in the bond markets. Specifically,
investor sentiment was particularly strong in the U.S., where prices on the
30-year Treasury bond and 10-year Treasury note rose to their highest levels in
over two years. This followed a largely positive economic report delivered by
Federal Reserve Chairman Greenspan in testimony before Congress. Effects of the
plunge in the Hong Kong stock market in late October spread rapidly throughout
the world's financial markets, including global bond markets. After continued
volatility in subsequent months made trading difficult, 1997 interest rate
trading ended on a positive note when U.S. and Japanese bond markets rallied as
a flight to safety from plunging stock markets around the world occurred in
December.

                  In energy markets, a slump in crude oil prices was
characteristic of its lackluster performance from the beginning of the year.
Early in 1997, volatility returned in the energy markets, reflecting the impact
of a winter significantly warmer than normal. By mid-year, the decline in prices
reversed sharply as Saudi Arabia and Iran, together representing about 45% of
OPEC's oil production, joined forces to pressure oil-producing nations to stay
within OPEC production quotas. In December, financial and economic problems in
Asia reduced demand for oil, and in combination with ample supplies, resulted in
crude oil prices declining once again.

                  1996 began with the East Coast blizzard, continuing
difficulties in the U.S. federal budget talks and an economic slowdown having a
negative impact on many markets. The Fund was profitable in January due to the
strong profits in currency trading as the U.S. dollar reached a 23-month high
against the Japanese yen. In February, however, the Fund incurred its worst
monthly loss due to the sudden reversals in several strong price trends and
considerable volatility in the currency and financial markets. During March,
large profits were taken in the crude oil and gasoline markets as strong demand
continued and talks between the United Nations and Iraq were suspended. This
trend continued into the second quarter, during which strong gains were also
recognized in the agricultural markets as a combination of drought and excessive
rain drove wheat and grain prices to historic highs. In the late summer and
early fall months, the Fund continued to trade profitably as trending prices in
a number of key markets favorably impacted the Fund's performance. In September
heating oil hit a five-year high on soaring prices in Europe, and the Fund was
also able to capitalize on downward trends in the metals markets. Strong trends
in the currency and global bond markets produced significant gains in October
and November, but the year ended with declining performance as December
witnessed the reversal of several strong upward trends and increased volatility
in key markets.

Variables Affecting Performance
-------------------------------

                  The principal variables which determine the net performance of
the Fund are gross profitability and interest income. Gross profitability is, in
turn, affected by the percentage of the Fund's assets allocated to trading.

                  During all periods set forth under "Selected Financial Data,"
the interest rates in many countries were at unusually low levels. The low
interest rates in the United States (although higher than in many other
countries) negatively impacted revenues because interest income is typically a
major component of the Fund's profitability. In addition, low interest rates are
frequently associated with reduced fixed income market volatility, and in static
markets the Fund's profit potential generally tends to be diminished. On the
other hand, during periods of higher interest rates, the relative attractiveness
of a high risk investment such as the Fund may be reduced as compared to high
yielding and much lower risk fixed-income investments.

                  The Fund's Brokerage Commissions and Administrative Fees are a
constant percentage of the Fund's assets allocated to trading and total assets,
respectively. The only Fund costs (other than the insignificant currency trading
costs) which are not based on a percentage of the Fund's assets (allocated to
trading or total) are the Profit Shares payable to the Advisors on an
Advisor-by-Advisor basis. During periods when Profit Shares are a high
percentage of net trading gains, it is likely that there has been substantial
performance non-correlation among the Advisors (so that the total Profit Shares
paid to those Advisors which have traded profitably are a high percentage, or
perhaps even in excess, of the total profits recognized, as other Advisors have
incurred offsetting losses, reducing overall trading gains but not the Profit
Shares paid to the successful Advisors) -- suggesting the likelihood of
generally trendless, non-consensus markets.

                  Unlike many investment fields, there is no meaningful
distinction in the operation of the Fund between realized and unrealized
profits. Most of the contracts traded by the Fund are highly liquid and can be
closed out at any time.

                  Except in unusual circumstances, factors -- regulatory
approvals, cost of goods sold, employee relations and the like -- which often
materially affect an operating business have virtually no impact on the Fund.

<PAGE>
 
The Different Series of Units
-----------------------------

                  All series of Units trade in a common trading account and are
subject to the same method of calculating their fees. Furthermore, any
discretionary action taken by MLIP -- e.g., adjusting trading leverage -must be
done in such a way that all Units have the same percentage of capital allocated
to trading after the adjustment (this restructuring applies only to Units issued
after May 1, 1997). Despite these fundamental similarities among the different
series, because the series begin trading at different times they are likely, as
a result of trading profits and losses, to pay different Profit Shares (although
to the same group of Advisors) and have different Net Asset Values. The series
offered since May 1, 1997 have begun trading at 85%-95% leverage. Series issued
before May 1, 1997 began trading at 60%-75% leverage.

Liquidity; Capital Resources
----------------------------

                  The Fund sells no securities other than the Units. The Fund
borrows only to a limited extent and only on a strictly short-term basis in
order to finance losses on non-U.S. dollar denominated trading positions pending
the conversion of the Fund's dollar deposits. These borrowings are at a
prevailing short-term rate in the relevant currency. 

                  The Fund's assets are held primarily in short-term debt
securities with maturities under one year, and to a lesser extent in short- and
mid-term debt securities with maturities up to five years, as well as in cash.
The Net Asset Value of the Fund's cash and financial instruments is not
materially affected by inflation. Changes in interest rates, which are often
associated with inflation, could cause the value of certain of the Fund's debt
securities to decline, but only to a limited extent. More importantly, changes
in interest rates could cause periods of strong up or down price trends, during
which the Fund's profit potential generally increases. Inflation in commodity
prices could also generate price movements which the strategies might
successfully follow.

                  The Fund's assets are held in cash and highly liquid U.S.
government securities. Accordingly, except in very unusual circumstances, the
Fund should be able to close out any or all of its open trading positions and
liquidate any or all of its securities holdings quickly and at market prices.
This permits an Advisor to limit losses as well as reduce market exposure on
short notice should its strategies indicate doing so. In addition, because there
is a readily available market value for the Fund's positions and assets, the
Fund's monthly Net Asset Value calculations are precise, and investors need only
wait 10 business days to receive the full redemption proceeds of their Units.

         Year 2000 Compliance Initiative

                  As the millennium approaches, Merrill Lynch has undertaken
initiatives to address the Year 2000 problem (the "Y2K problem"). The Y2K
problem is the result of a widespread programming technique that causes computer
systems to identify a date based on the last two numbers of a year, with the
assumption that the first two numbers of the year are "19". As a result, the
year 2000 would be stored as "00," causing computers to incorrectly interpret
the year as 1900. Left uncorrected, the Y2K problem may cause information
technology systems (e.g., computer databases) and non-information technology
systems (e.g., elevators) to produce incorrect data or cease operating
completely.

                  Merrill Lynch believes that it has identified and evaluated
its internal Y2K problem and that it is devoting sufficient resources to
renovating technology systems that are not already Year 2000 compliant. The
resource-intensive renovation phase (as further discussed) of Merrill Lynch's
Year 2000 efforts was approximately 95% completed as of January 31, 1999.
Merrill Lynch will focus primarily on completing its renovation and testing and
on integration of the Year 2000 programs of recent acquisitions during the
remainder of 1999. In order to focus attention on the Y2K problem, management
has deferred certain other technology projects: however, this deferral is not
expected to have a material adverse effect on the company's business, results of
operations, or financial condition.

                  The failure of Merrill Lynch's technology systems relating to
a Y2K problem would likely have a material adverse effect on the company's
business, results of operations, and financial condition. This effect could
include disruption of normal business transactions, such as the settlement,
execution, processing, and recording of trades in securities, commodities,
currencies, and other assets. The Y2K problem could also increase Merrill
Lynch's exposure to risk and its need for liquidity.

                  In 1995, Merrill Lynch established the Year 2000 Compliance
Initiative, which is an enterprisewide effort to address the risks associated
with the Y2K problem, both internal and external. The Year 2000 Compliance
Initiative's efforts to address the risks associated with the Y2K problem have
been organized into six phases: planning, pre-renovation, renovation, production
testing, certification, and integration testing.

                  The planning phase involved defining the scope of the Year
2000 Compliance Initiative, including its annual budget and strategy, and
determining the level of expert knowledge available within Merrill Lynch
regarding particular systems or applications. The pre-renovation phase involved
developing a detailed enterprisewide inventory of applications and systems,
identifying the scope of necessary renovations to each application system, and
establishing a conversion schedule. During the renovation phase, source code is
actually converted, date fields are expanded or windowed (windowing is used on
an exception basis only), test data is prepared, and each system or application
is tested using a variety of Year 2000 scenarios. The production testing phase
validates that a renovated system is functionally the same as the existing
production version, that renovation has not introduced defects, and that
expanded or windowed date fields continue to handle current dates properly. The
certification phase validates that a system can run successfully in a Year 2000
environment. The integration testing phase, which will occur throughout 1999,
validates that a system can successfully interface with both internal and
external systems. Finally, as Merrill Lynch continues to implement new systems,
they are also being tested for Year 2000 readiness.

                  In 1996 and 1997, as part of the planning and pre-renovation
phases, both plans and funding of plans for inventory, preparation, renovation,
and testing of computer systems for the Y2K problem were approved. All plans for
both mission-critical and non-mission-critical systems are tracked and
monitored. The work associated with the Year 2000 Compliance Initiative has been
accomplished by Merrill Lynch employees, with the assistance of consultants
where necessary.

                  As part of the production testing and certification phases,
Merrill Lynch has performed, and will continue to perform, both internal and
external Year 2000 testing intended to address the risks from the Y2K problem.
As of January 31, 1999, production testing was approximately 93% completed. In
July 1998, Merrill Lynch participated in an industrywide Year 2000 systems test
sponsored by the Securities Industry Association ("SIA"), in which selected
firms tested their computer systems in mock stock trades that simulated dates in
December 1999 and January 2000. Merrill Lynch will participate in further
industrywide testing sponsored by the SIA, currently scheduled for March and
April 1999, which will involve an expanded number of firms, transactions, and
conditions. Merrill Lynch also participated in various other domestic and
international industry tests during 1998.

                  Merrill Lynch continues to survey and communicate with third
parties whose Year 2000 readiness is important to the company. Information
technology and non-information technology vendors and service providers are
contacted in order to obtain their Year 2000 compliance plans. Based on the
nature of the response and the importance of the product or service involved,
Merrill Lynch determines if additional testing is needed. The results of these
efforts are maintained in a database that is accessible throughout the firm.
Third parties that have been contacted include transactional counterparties,
exchanges, and clearinghouses; a process to access and rate their responses has
been developed. This information as well as other Year 2000 readiness
information on particular countries and their political subdivisions will be
used by Merrill Lynch to manage risk resulting from the Y2K problem. Management
is unable at this point to ascertain whether all significant third parties will
successfully address the Y2K problem. Merrill Lynch will continue to monitor
third parties' Year 2000 readiness to determine if additional or alternative
measures are necessary. In connection with information technology and
non-information technology products and services, contingency plans, which are
developed at the business unit level, may include selection of alternative
vendors or service providers and changing business practices so that a
particular system is not needed. In the case of securities exchanges and
clearinghouses, risk mitigation could include the re-routing of business. In
light of the interdependency of the parties in or serving the financial markets,
however, there can be no assurance that all Y2K problems will be identified and
remediated on a timely basis or that all remediation will be successful. The
failure of exchanges, clearing organizations, vendors, service providers,
counterparties, regulators, or others to resolve their own processing issues

                                       21
<PAGE>
 
in a timely manner could have a material adverse effect on Merrill Lynch's
business, results of operations, and financial condition.

                  At year-end 1998, the total estimated expenditures for the
entire Year 2000 Compliance Initiative were approximately $425 million, of which
approximately $125 million was remaining. The majority of these remaining
expenditures are expected to cover testing, risk management, and contingency
planning. There can be no assurance that the costs associated with such
remediation efforts will not exceed those currently anticipated by Merrill
Lynch, or that the costs associated with the remediation efforts or the possible
failure of such remediation efforts would not have a material adverse effect on
Merrill Lynch's business, results of operations, or financial condition.

         European Economic and Monetary Union ("EMU") Initiative
         -------------------------------------------------------

                  As of January 1, 1999, the "euro" was adopted as the common
legal currency of participating member states of the EMU. As a consequence of
the introduction of and conversion to the euro, Merrill Lynch was required to
make significant changes to nearly 200 global business systems in order to
reflect the substitution of the euro for the 11 member national currencies and
the European currency unit. The introduction of the euro brings about
fundamental changes in the structure and nature of European financial markets,
including the creation of a unified, more liquid capital market in Europe. As
financial markets in EMU member states converge and local barriers are removed,
competition is expected to increase.

                  The introduction of the euro affects all Merrill Lynch
facilities that transact, distribute, or provide custody or recordkeeping for
securities or cash denominated in the currency of a participating member state.
Merrill Lynch's systems or procedures that handle such securities or cash were
modified in order to implement the conversion to the euro. The implementation
phase is continuing into the first quarter of 1999 to resolve any
post-conversion issues. The success of Merrill Lynch's euro conversion efforts
was dependent on the euro-compliance of third parties, such as trading
counterparties, financial intermediaries (e.g., securities and commodities
exchanges, depositories, clearing organizations, and commercial banks), and
vendors.

                  As of the end of the 1998 fiscal year, the total estimated
expenditures associated with the introduction of and conversion to the euro were
approximately $79 million, of which $1 million is remaining to be spent during
the first quarter of 1999 on compliance efforts and project administration.
Management believes that it has identified and evaluated all of the systems and
operational modifications necessary for the conversion to the euro. On January
4, 1999 and since then, Merrill Lynch has conducted normal business operations,
having successfully completed its conversion program. Management does not expect
the introduction of the euro to have a negative effect on its future business,
currency risk, or competitive positioning in the European markets.

Item 7A:  Quantitative and Qualitative Disclosures About Market Risk
          ----------------------------------------------------------

Introduction

       Past Results Not Necessarily Indicative of Future Performance
       -------------------------------------------------------------

                  The Fund is a speculative commodity pool. Unlike an operating
company, the risk of market sensitive instruments traded by it is integral, not
incidental, to the Fund's main line of business.

                  Market movements result in frequent changes in the fair market
value of the Fund's open positions and, consequently, in its earnings and cash
flow. The Fund's market risk is influenced by a wide variety of factors,
including the level and volatility of interest rates, exchange rates, equity
price levels, the market value of financial instruments and contracts, the
diversification effects among the Fund's open positions and the liquidity of the
markets in which it trades.

                  The Fund, under the direction of the Trading Advisors, rapidly
acquires and liquidates both long and short positions in a wide range of
different markets. Consequently, it is not possible to predict how a possible
future market scenario will affect performance, and the Fund's past performance
is not necessarily indicative of its future results.

                                       22
<PAGE>
 
                  Value at Risk is a measure of the maximum amount which the
Fund could reasonably be expected to lose in a given market sector. However, the
inherent uncertainty of the Fund's speculative trading and the recurrence in the
markets traded by the Fund of market movements far exceeding expectations could
result in actual trading or non-trading losses far beyond the indicated Value at
Risk or the Fund's experience to date (i.e., "risk of ruin"). In light of the
foregoing as well as the risks and uncertainties intrinsic to all future
projections, the inclusion of the quantification in this section should not be
considered to constitute any assurance or representation that the Fund's losses
in any market sector will be limited to Value at Risk or by the Fund's attempts
to manage its market risk.

Quantifying the Fund's Trading Value at Risk
--------------------------------------------

       Quantitative Forward-Looking Statements
       ---------------------------------------

                  The following quantitative disclosures regarding the Fund'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 Fund's risk exposure in the various market sectors traded
by the Advisors is quantified below in terms of Value at Risk. Due to the Fund's
mark-to-market accounting, any loss in the fair value of the Fund's open
positions is directly reflected in the Fund's earnings (realized or unrealized)
and cash flow (at least in the case of exchange-traded contracts in which
profits and losses on open positions are paid daily through variation margin).

                  Exchange maintenance margin requirements have been used by the
Fund as the measure of its Value at Risk. Maintenance margin requirements are
set by exchanges to equal or exceed the maximum loss in the fair value of any
given contract incurred in 95% - 99% of the one-day time periods included in the
historical sample (generally approximately one year) researched for purposes of
establishing margin levels. Maintenance margin levels are established by dealers
and exchanges using historical price studies as well as an assessment of current
market volatility and economic fundamentals to provide a probabilistic estimate
of the maximum expected near-term one-day price fluctuation.

                  In the case of market sensitive instruments which are not
exchange-traded (almost exclusively currencies in the case of the Fund), the
margin requirements for the equivalent futures positions have been used as Value
at Risk. In those rare cases in which a futures-equivalent margin is not
available, dealers' margins have been used.

                  The fair value of the Fund's futures and forward positions
does not have any optionality component. However, certain of the Advisors trade
commodity options. The Value at Risk associated with options is reflected in the
following table as the margin requirement attributable to the instrument
underlying each option.

                  100% positive correlation in the different positions held in
each market risk category has been assumed. Consequently, the margin
requirements applicable to the open contracts have been aggregated to determine
each trading category's aggregate Value at Risk. The diversification effects
resulting from the fact that the Fund's positions are rarely, if ever, 100%
positively correlated have not been reflected.

The Fund's Trading Value at Risk in Different Market Sectors
------------------------------------------------------------

                  The following table indicates the trading Value at Risk
associated with the Fund's open positions by market category as of December 31,
1998. As of December 31, 1998, the Fund's total capitalization was approximately
$79,106,838, of which $63,424,815 was allocated to trading.

Material Limitations on Value at Risk as an Assessment of Market Risk
---------------------------------------------------------------------

                  The face value of the market sector instruments held by the
Fund is typically many times the applicable maintenance margin requirement
(maintenance margin requirements generally ranging between approximately 1% and
10% of contract face value) as well as many times the capitalization of the
Fund. The magnitude of the Fund's open positions creates a "risk of ruin" not
typically found in most other investment vehicles. Because of the size of its
positions, certain market conditions - unusual, but historically recurring from
time to time - could cause the Fund to incur severe losses over a short period
of time. Even comparatively minor losses could cause MLIP to further deleverage
or terminate the Fund's trading. The foregoing Value at Risk table - as well as
the past performance of the Fund - gives no indication of this "risk of ruin."

Non-Trading Risk
----------------

         Foreign Currency Balances; Cash on Deposit with MLF
         ---------------------------------------------------

                  The Fund has non-trading market risk on its foreign cash
balances not needed for margin. However, these balances (as well as the market
risk they represent) are immaterial.

                  The Fund also has non-trading market risk on the approximately
20% of its assets which are held in cash at MLF. The value of this cash is not
interest rate sensitive, but there is cash flow risk in that if interest rates
decline so will the cash flow generated on these monies. This cash flow risk is
immaterial.

                  Certain unusual market conditions could cause greater interest
rate related losses on the Fund's non-trading instruments in excess of those
suggested by the foregoing quantification, but given the fact that virtually
none of the Fund's Government Securities have any optionality or derivative
multiplier feature, MLIP believes that this would be highly unlikely.

Qualitative Disclosures Regarding Primary Trading Risk Exposures
----------------------------------------------------------------

                  The following qualitative disclosures regarding the Fund's
market risk exposures - except for (i) those disclosures that are statements of
historical fact and (ii) the descriptions of how the Fund 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 Fund's primary market risk exposures as well as the strategies used and
to be used by MLIP and the Advisors for managing such exposures are subject to
numerous uncertainties, contingencies and risks, any one of which could cause
the actual results of the Fund'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 Fund. There can be no assurance that the
Fund's current market exposure and/or risk management strategies will not change
materially or that any such strategies will be effective in either the short- or
long-term. Investors must be prepared to lose all or substantially all of the
time value of their investment in the Fund.

                  The following were the primary trading risk exposures of the
Fund as of December 31, 1998, by market sector.

                  Interest Rates. Interest rate risk is the principal market
                  --------------
exposure of the Fund. Interest rate movements directly affect the price of
derivative sovereign bond positions held by the Fund and indirectly 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 Fund's profitability. The Fund's primary interest rate exposure is to
interest rate fluctuations in the United States and the other G-7 countries.
However, the Fund also takes positions in the government debt of smaller nations
? e.g., New Zealand and Australia. The General Partner anticipates that G-7
interest rates will remain the primary market exposure of the Fund for the
foreseeable future.

                  Currencies. The Fund trades in a large number of currencies.
                  ----------
However, the Fund's major exposures have typically been in the dollar/yen,
dollar/mark and dollar/pound positions. The General Partner does not anticipate
that the risk profile of the Fund's currency sector will change significantly in
the future, although it is difficult at this point to predict the effect of the
introduction of the Euro on the Advisors' currency trading strategies. The
currency trading Value at Risk figure includes foreign margin amounts converted
into U.S. dollars with an incremental adjustment to reflect the exchange rate
risk of maintaining Value at Risk in a functional currency other than dollars.

                  Stock Indices. The Fund's primary equity exposure is to G-7
                  -------------
equity index price movements. As of December 31, 1998, the Fund's primary
exposures were in the S&P 500, Financial Times (England), Nikkei (Japan) and DAX
(Germany) stock indices. The General Partner anticipates little, if any, trading
in non-G-7 stock indices. The Fund is primarily exposed to the risk of adverse
price trends or static markets in the major U.S., European and Japanese indices.

                  Metals. The Fund's primary metals market exposure is to
                  ------
fluctuations in the price of gold and silver. Although certain of the Advisors
will, from time to time, trade base metals such as aluminum, copper and tin, the
principal market exposures of the Fund have consistently been in the precious
metals, gold and silver (and, to a much lesser extent, platinum). The Advisors'
gold trading has been increasingly limited due to the long-lasting and mainly
non-volatile decline in the price of gold over the last 10?15 years. However,
silver prices have remained volatile over this period, and the Advisors have,
from time to time, taken substantial positions as they have perceived market
opportunities to develop. The General Partner anticipates that gold and silver
will remain the primary metals market exposure for the Fund.

                                       26
<PAGE>
 
                  Commodities. The Fund's primary commodities exposure is to
                  -----------
agricultural price movements which are often directly affected by severe or
unexpected weather conditions. Soybeans, grains and orange juice accounted for
the substantial bulk of the Fund's commodities exposure as of December 31, 1998.
In the past, the Fund has had material market exposure to live cattle and
hogbellies and may do so again in the future. However, the General Partner
anticipates that the Advisors will maintain an emphasis on soybeans, grains and
orange juice, in which the Fund has historically taken its largest positions.

                  Energy. The Fund's primary energy market exposure is to gas
                  ------
and oil price movements, often resulting from political developments in the
Middle East. Although the Advisors trade natural gas to a limited extent, oil is
by far the dominant energy market exposure of the Fund. Oil prices are currently
depressed, but they can be volatile and substantial profits and losses have been
and are expected to continue to be experienced in this market.

Qualitative Disclosures Regarding Non-Trading Risk Exposure
-----------------------------------------------------------

         The following were the only non-trading risk exposures of the Fund as
of December 31, 1998.

                  Foreign Currency Balances. The Fund's primary foreign currency
                  -------------------------
balances are in Japanese yen, German marks, British pounds and French francs.
The Fund has de minimis exchange rate exposure on these balances.

                  Securities Positions. The Fund holds only cash or
                  --------------------
interest-bearing Government Securities. The Fund's market exposure in
instruments held other than for trading is in the interest rate risk exposure of
the Fund's Government Securities portfolio, managed by MLAM pursuant to policies
established by MLIP for which MLAM assumes no responsibility. MLIP manages the
risk of the Fund's MLAM account by imposing limitations both on the overall
duration of the portfolio (two years) and on the maximum duration of any
Government Securities held by MLAM (no later than the Principal Assurance Date
for the most recently issued Series of Units). MLIP has applied essentially the
same risk control policies to the Fund's MLAM account since inception, and the
Fund has never experienced a material loss on this account. In a period of
rapidly rising interest rates (since the Fund's inception in 1994, interest
rates have generally declined until quite recently), the Fund could incur
marked-to-market losses on its MLAM account, but MLIP would attempt to prevent
or control these losses by further reducing the permissible durations of the
Fund's Government Securities in order to reduce the interest rate sensitivity of
these instruments.

Qualitative Disclosures Regarding Means of Managing Risk Exposure
-----------------------------------------------------------------

         Trading Risk

                  The General Partner has procedures in place intended to
control market risk exposure, although there can be no assurance that they will,
in fact, succeed in doing so. These procedures focus primarily on monitoring the
trading of the Advisors selected from time to time for the Fund, adjusting the
percentage of the Fund's total assets investing in the Trading Partnership with
respect to each series of Units and reviewing outstanding positions for
over-concentrations both on an Advisor-by-Advisor and on an overall Fund
basis. While MLIP does not itself intervene in the markets to hedge or diversify
the Fund's market exposure, MLIP may urge Advisors to reallocate positions, or
itself reallocate Partnership assets among Advisors (although typically only as
of the end of a month), in an attempt to avoid over-concentrations. However,
such interventions are unusual.

                  One important aspect of the General Partner's risk controls is
its adjustments to the leverage at which each Series of Units trades. By
controlling the percentage of each Series' assets investing in the Trading
Partnership, the General Partner can directly affect the market exposure of the
Fund. Leverage control is the principal means by which the General Partner hopes
to be able to ensure that Merrill Lynch is never required to make any payments
under its guarantee that the Net Asset Value per Unit of each series will equal
no less than $100 as of the Principal Assurance Date for such series, subject to
the limitation that all Series of Units issued after May 1997 must be adjusted,
if any such Series is adjusted, so that they all trade at the same degree of
leverage.

                  At the Advisor level, each Advisor applies its own risk
management policies to its trading. These policies generally limit the total
exposure that may be taken per "risk unit" of assets under management. In
addition, many Advisors follow diversification guidelines (often formulated in
terms of the maximum margin which they will commit to positions in any one
contract or group of related contracts), as well as imposing "stop-loss" points
at which open positions must be closed out. Occasionally, Advisors will limit
the market exposure of their Fund account through 

                                       27
<PAGE>
 
acquiring put or call options which "collar" the risk of open positions.
However, because of the typically high degree of liquidity in the markets traded
by the Fund and the expense of acquiring options, most Advisors rely simply on
stop-loss policies, requiring the liquidation of positions once losses of a
certain magnitude have been incurred.

                  Certain Advisors treat their risk control policies as strict
rules; others only as general guidelines for controlling risk.

         Non-Trading Risk
         ----------------

                  The Fund controls the non-trading exchange rate risk of these
balances by regularly converting its foreign currency balances back into dollars
(no less frequently than twice a month, and more frequently if a particular
foreign currency balance becomes unusually high).

                  The General Partner controls the interest-rate risk of the
Fund's non-trading instruments (Government Securities invested by MLAM for cash
management purposes) by limiting the overall duration of such instruments to no
more than two years and the maximum duration of any Government Securities held
by the Fund to no later than the Principal Assurance Date for the most recently
issued Series of Units. These risk control policies have been successful in the
Fund's operations to date, and MLIP does not anticipate any change in these
policies. However, where the interest rate environment changes materially, MLIP
might shorten the permissible duration of the Fund's Government Securities
portfolio.

                  The Fund has cash flow interest rate risk on its cash on
deposit with MLF in that declining interest rates would cause the income from
such cash to decline. However, a certain amount of cash or cash equivalents must
be held by the Fund in order to facilitate margin payments and pay expenses and
redemptions. MLIP does not take any steps to limit the cash flow risk on the
approximately 20% of its cash held on deposit at MLF.

Item 8:  Financial Statements and Supplementary Data
         -------------------------------------------

                  The financial statements required by this Item are included in
Exhibit 13.01.

                  The supplementary financial information ("selected quarterly
financial data" and "information about oil and gas producing activities")
specified by Item 302 of Regulation S-K is not applicable. The General Partner
promoted the Fund and is its controlling person.

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

                  There were no changes in or disagreements with independent
auditors on accounting and financial disclosure.

Item 13:  Certain Relationships and Related Exchange of Futures Transactions
          ------------------------------------------------------------------

         (a)      Transactions Between Merrill Lynch and the Fund
                  -----------------------------------------------

                  All of the service providers to the Fund, other than the
Advisors, are affiliates of Merrill Lynch. Merrill Lynch negotiated with the
Advisors over the level of its advisory fees and Profit Share. However, none of
the fees paid by the Fund to any Merrill Lynch party were negotiated, and they
are higher than would have been obtained in arm's-length bargaining.

                  The Fund pays Merrill Lynch substantial Brokerage Commissions
and Administrative Fees as well as bid-ask spreads on forward currency trades.
The Fund also pays MLF interest on short-term loans extended by MLF to cover
losses on foreign currency positions.

                  Within the Merrill Lynch organization, MLIP is the direct
beneficiary of the revenues received by different Merrill Lynch entities from
the Fund. MLIP controls the management of the Fund and serves as its promoter.
Although MLIP has not sold any assets, directly or indirectly, to the Fund, MLIP
makes substantial profits from the Fund due to the foregoing revenues.

                  No loans have been, are or will be outstanding between MLIP or
any of its principals nd the Fund.

                  MLIP pays substantial selling commissions and trailing
commissions to MLPF&S for distributing the Units. MLIP is ultimately paid back
for these expenditures from the revenues it receives from the Fund.

         (b)      Certain Business Relationships:
                  ------------------------------

                  MLF, an affiliate of the General Partner, acts as the
principal commodity broker for the Partnership.

                  In 1998, the Partnership expensed: (i) Brokerage Commissions
of $6,159,359 to the Commodity Broker, which included $1,154,486 in consulting
fees earned the Trading Advisors; and (ii) Administrative Fees of $193,861 to
MLIP. In addition, MLIP and its affiliates may have derived certain economic
benefit from possession of the Fund's assets, as well as from foreign exchange
and EFP trading.

                  See Item 1(c), "Narrative Description of Business -- Charges"
and "-- Description of Current Charges" for a discussion of other business
dealings between MLIP affiliates and the Partnership.

         (c)      Indebtedness of Management:
                  --------------------------

                  The Partnership is prohibited from making any loans, to
management or otherwise.

         (d)      Transactions with Promoters: 
                  ---------------------------

                  Not applicable.
