1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

   These financial statements have been prepared without audit.  In the opinion
   of management, the financial statements contain all adjustments (consisting
   of only normal recurring adjustments) necessary to present fairly the
   financial position of  ML Principal Protection L.P. (the "Partnership" or the
   "Fund") as of June 30, 1997 and December 31, 1996 and the results of its
   operations for the six months ended June 30, 1997 and 1996.  However, the

4.    SUBSEQUENT EVENTS

   On July 1, 1997 distributions were announced with respect to Series D Units
   and Series H Units.  Series D Units received an annual fixed rate
   distribution equal to $3.50 per Unit  as well as a discretionary distribution
   equal to $1.00 per Unit.  Series H Units received an annual fixed rate
   distribution equal to $3.50 per Unit as well as a discretionary distribution
   equal to $2.50 per Unit.

Item 2:  Management's Discussion and Analysis of Financial Condition and Results
         -----------------------------------------------------------------------
of Operations
- -------------

Operational Overview: Advisor Selections
- ----------------------------------------

         Due to the nature of the Fund's business, its results of operations
depend on Merrill Lynch Investment Partners' ("MLIP") ability to select Advisors
and determine the appropriate percentage of each series' assets to allocate to
them for trading, as well as the Advisors' ability to recognize and capitalize
on trends and other profit opportunities in different sectors of the world
commodity markets.  MLIP's Advisor selection procedure and leveraging analysis,
as well as the Advisors' trading methods, are confidential, so that
substantially the only information that can be furnished regarding the Fund's
results of operations is contained in the performance record of its trading.
Unlike operating businesses, general economic or seasonal conditions do not
directly affect the profit potential of the Fund, and its past performance is
not necessarily indicative of future results.  Because of the speculative nature
of its trading, operational or economic trends have little relevance to the
Fund's results.  MLIP believes, however, that there are certain market
conditions, for example, markets with strong price trends, in which the Fund has
a better likelihood of being profitable than in others.

         As of July 1, 1997, the trading assets attributable to each series of
Units were allocated approximately as follows (either 60% or 75% of each series'
total capital being allocated to trading):
 
         Chesapeake Capital Corporation     19.00
         John W. Henry & Company, Inc.      15.00
         Non-"Core" Advisors                66.00
                                           ------
         Total                             100.00%

         MLIP expects to continue to change both allocations and Advisor
selections from time to time without advance notice to existing investors.

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

Results of Operations - General
- -------------------------------

         MLIP believes that multi-Advisor futures funds should be regarded as
medium- to long-term investments but, unlike an operating business, it is
difficult to identify "trends" in the Fund's operations and virtually impossible
to make any predictions regarding future results based on results to date.

         Markets in which sustained price trends occur with some frequency tend
to be more favorable to managed futures investments than "whipsaw," "choppy"
markets, but (i) this is not always the case, (ii) it is impossible to predict
when trending markets will occur and (iii) different Advisors are affected
differently by trends in general as well as by particular types of trends.

         The Fund controls credit risk in its trading in the derivatives markets
by trading only through Merrill Lynch entities which MLIP believes to be
creditworthy.  The Fund attempts to control the market risk inherent in its
derivatives trading by utilizing a multi-advisor, multi-strategy structure.
This structure purposefully attempts to diversify the Fund's Advisor group among
different strategy types and market sectors in an effort to reduce risk
(although the Fund's portfolio currently emphasizes technical and trend-
following approaches).  The market risk to the Fund is, in any event, limited by
the deleveraged character of its trading (initially, either 60% or 75% of each
series' assets, and in certain cases possibly less, is allocated to trading) and
the related "principal protection" feature of the Fund.

Performance Summary
- -------------------

         During the first six months of 1996, the Fund's average month-end Net
Assets equaled $83,909,857, and the Fund recognized trading gains of $2,201,924
or 2.62% of average month-end Net Assets.  Brokerage commissions of $2,391,122
or 2.85%, Administrative fees of $64,625 or 0.08% and Profit Shares of $243,603
or 0.29% of average month-end Net Assets were paid.  Interest income of
$2,289,595 or 2.73% of average month-end Net Assets resulted in net gain of
$1,778,363 (before organizational and initial offering cost reimbursement
payments of $39,850, and after deduction of MLIP's "minority interest" of 13,806
in the Trading Partnership), or 2.12% of average month-end Net Assets which
resulted in 2.22% increase in the Net Asset Value per Series A Units (before
distribution), 2.09% increase in the Net Asset Value per Series B Units (before
distribution), 2.13% increase in the Net Asset Value per Series C Units (before
distribution), 2.12% increase in the Net Asset Value per Series D 

                                       9

 
Units, 2.08% increase in the Net Asset Value per Series E Units since December
31, 1995, a 1.72% increase in the Net Asset Value per Series F Units since
January 1996 and a .35% increase in the Net Asset Value per Series G Units since
April 1996. The performance of the different Series of Units differs somewhat
over the same period due primarily to profit share calculation differences
resulting from the different times at which the various Series began trading.

         During the first six months of 1997, the Fund's average month-end Net
Assets equaled $77,560,546 and the Fund recognized trading gains of $2,318,780
or 2.99% of average month-end Net Assets.  Brokerage commissions of $2,141,245
or 2.76%, Administrative fees of $61,179 or .08% and Profit Shares of $498,398
or .64% of average month-end Net Assets were paid.  Interest income of
$2,182,912 or 2.81% of average month-end Net Assets resulted in a net gain of
$1,788,581 (before organizational and initial offering cost reimbursement
payments of $39,851 and after deduction of MLIP's "minority interest" of $12,289
in the Trading Partnership), or 2.31% of average month-end Net Assets which
resulted in a 2.12% increase in the NAV per Series A Units, 1.99% increase
(before distribution)  in the NAV per Series B Units, 2.19% increase (before
distribution) in the NAV per Series C Units, 2.08% increase (before
distribution)  in the NAV per Series D Units, 2.08% increase (before
distribution) in the NAV per Series E Units, 1.96% increase (before
distribution) in the NAV per Series F Units, 2.17% increase (before
distribution) in the NAV per Series G Units, 2.12% increase (before
distribution) in the NAV per Series H Units since December 31, 1996 and a .71%
increase in the NAV per Series K Units since May 1997.  The performance of
different Series of Units differs somewhat over the period due primarily to the
profit share calculation differences resulting from the different times at which
the various Series began trading.

         During the first six months of 1997 and 1996, the Fund experienced 8
profitable months and 4 unprofitable months.

Importance of Market Factors
- ----------------------------

         Comparisons between the Fund's performance in a given period in one
fiscal year to the same period in a prior year are unlikely to be meaningful,
given the uncertainty of price movements in the markets traded by the Fund.  In
general, MLIP expects that the Fund is most likely to trade successfully in
markets which exhibit strong and sustained price trends.  The current Advisor
group emphasizes technical and trend-following methods.  Consequently, one would
expect that in trendless, "choppy" markets the Fund would likely be
unprofitable, while in markets in which major price movements occur, the Fund
would have its best profit potential (although there could be no assurance that
the Fund would, in fact, trade profitably).  However, trend-followers not
infrequently will miss major price movements, and market corrections can result
in rapid and material losses (sometimes as much as 5% in a single day).
Although MLIP monitors market conditions and Advisor performance on an ongoing
basis in overseeing the Fund's trading, MLIP does not attempt to "market
forecast" or to "match" trading styles with predicted market conditions.
Rather, MLIP concentrates on quantitative and qualitative analysis of
prospective Advisors, as well as on statistical studies of the historical
performance parameters of different Advisor combinations in selecting Advisors
and allocating and reallocating Fund assets among them.

         Because managed futures advisors' strategies are proprietary and
confidential and market movements unpredictable, selecting advisors to implement
speculative trading strategies involves considerable uncertainty.  Furthermore,
the concentration of the Fund's current Advisor portfolio, both in terms of the
number of managers retained and the common emphasis of their strategies on
technical and trend-following methods, increases the risk that unexpectedly bad
performance, turbulent market conditions or a combination of the two will result
in significant losses.

Interest Income
- ---------------

         The Fund's interest income varies from month to month due to a portion
of such income representing the yield enhancement return achieved by MLAM rather
than periodic interest accruals.  Although there can be no assurance that the
Fund will not incur losses in its yield enhancement activities in the future, to
date MLAM has achieved a yield for the Fund (on approximately 80% to 90% of the
Fund's assets managed by MLAM) of approximately 2.89% (annualized) over the
prevailing 91-day Treasury bill rate.

Liquidity
- ---------

         The Fund's assets, including the assets managed by MLAM, are available
to margin the Fund's futures positions and earn interest income and to be
withdrawn, as necessary, to pay redemptions and expenses.  Other than potential
limitations on liquidity, due, for example, to daily price fluctuation limits,
which are inherent in the Fund's futures and forward trading, the Fund's assets
are highly liquid and are expected to remain so.  To date, the Fund has
experienced no meaningful periods of illiquidity in any of the numerous markets
traded by the Advisors.

                                       11

 
         Although Units may be redeemed at any month-end, no one who cannot
afford to commit funds to a comparatively illiquid investment should subscribe
to the Fund (redemption penalties apply through the end of the first twelve
months after the beginning of the calendar quarter as of which a Unit is
issued).  MLIP believes that investors who are not prepared to regard the Fund
essentially as a medium- to long-term investment should not purchase Units.

         MLIP makes annual fixed-rate and, possibly, additional discretionary
distributions to investors from the assets attributable to their respective
series of Units.  Such distributions are made as of each Issuance Anniversary
for the various series.  The Series A Units and Series B Units each received
both fixed-rate and discretionary distributions of $3.50 and $2.50 (a total
distribution of $6.00) as of their respective first Issuance Anniversaries. The
Series C Units received a fixed rate distribution of $3.50 on its respective
first Issuance Anniversary.  The Series D Units received a fixed rate
distribution of $3.50 on its respective first Issuance Anniversary.  The Series
E Units received a fixed rate distribution of $3.50 on its first Issuance
Anniversary. The Series F Units received both a fixed rate and discretionary
distribution of $3.50 and $2.50 (a total distribution of $6.00), respectively,
on its first Issuance Anniversary. The Series G Units received both a fixed rate
and discretionary distribution of $3.50 and $3.50 (a total distribution of
$7.00), respectively, on its first Issuance Anniversary.  The Series A Units
received both a fixed rate and discretionary distribution of $3.50 and $2.50,
respectively, (a total distribution of $6.00), respectively, on its second
Issuance Anniversary. The Series B Units received both a fixed rate and
discretionary distribution of $3.50 and $3.00 (a total distribution of $6.50) on
its second Issuance Anniversary. The Series C Units received both a fixed rate
and discretionary distribution of $3.50 and $4.00, respectively, (a total
distribution of $7.50) on its second Issuance Anniversary.

     In making discretionary distributions from the Fund, even though such
distributions are made only from cumulative profits, if any (as opposed to
fixed-rate annual distributions, which are made irrespective of profitability),
MLIP considers the importance of not depleting the assets of any particular
series to the point that subsequent losses could result in MLIP further
deleveraging the trading of such series.

         As of July 1, 1996, the Fund has changed its name to ML Principal
Protection L.P.  Such  change is due to the General Partner restructuring the
continuous offerings to be sold without a guaranteed annual fixed-rate
distribution or a discretionary distribution as previously offered under ML
Principal Protection Plus L.P.

Capital Resources
- -----------------

         Units are offered for sale as of the beginning of each calendar
quarter, and may be redeemed as of the end of each month.

         The amount of capital raised for the Fund does not have a significant
impact on its operations, as, other than a de minims organizational and initial
offering cost reimbursement obligation, the Fund has no capital expenditure or
working capital requirements other than for moneys to pay trading losses,
brokerage commissions, Administrative Fees and Profit Shares (all of which
should be generally proportional to the capital available to a particular series
of Units).  Within broad ranges of capitalization, the Advisors' trading
positions should increase or decrease in approximate proportion to the size of
the Fund account managed by each of them, respectively.

         The Fund raises additional capital only through the sale of Units.  The
Fund is prohibited from borrowing under the terms of the Limited Partnership
Agreement.

         Due to the nature of the Fund's business, substantially all of its
assets are and will be represented by cash, Government Securities and short-term
foreign sovereign debt obligations, while it maintains its primary market
exposure through futures and forward contract positions.

         Inflation is not a significant factor in the Fund's profitability,
although inflationary cycles can give rise to the type of major price movements
which can have a materially favorable or adverse impact on the Fund's
performance.

         Changes in the level of prevailing interest rates (a factor generally
associated with inflation) could have a material effect on the percentage of the
total capital attributable to various series of Units which is committed to
trading, as interest rates affect the calculation of the discounted minimum Net
Asset Value per Unit which ML&Co. has guaranteed to investors.

Item 1.  Legal Proceedings

         There are no pending legal proceedings to which the Partnership or the
         General Partner is a party.

         John W. Henry & Company, Inc. ("JWH") is one of the Advisors retained
by the Fund, managing approximately 15% of the Fund's assets committed to
trading as of July 1, 1997.  In September 1996, JWH was named in a co-defendant
in a class action lawsuit brought in the California Superior Court, Los Angeles
County and in the New York Supreme Court, New York County.  In November, JWH was
named as a co-defendant in a class action complaint filed in Superior Court of
the State of Delaware for Newcastle County unspecified damages, purport to be
brought on behalf of investors in certain Dean Witter, Discover & Co. ("Dean
Witter") commodity pools, some of which are advised by JWH, and are primarily
directed at Dean Witter alleged fraudulent selling practices in connection with
the marketing of those pools. JWH is essentially alleged to have aided and
abetted or directly participated with Dean Witter in those practices.  JWH
believes the allegations against it are without merit; it intends to contest
these allegations vigorously, and is convinced that it will be shown to have
acted properly and in the best interest of the investors.

      On June 24, 1997, the Commodity Futures Trading Commission("CFTC")
accepted an Offer of Settlement from Merrill Lynch Futures Inc. ("MLF") and
others, in a matter captioned "In the Matter of Mitsubishi Corporation and
Merrill Lynch Futures Inc., et al.", CFTC Docket No. 97-10, pursuant to which
MLF, without admitting or denying the allegations against it,  consented to a
finding by the CFTC that MLF had violated Section 4c(a)(A) of the Commodity
Exchange Act (the "Act"), relating to wash sales, and CFTC Regulation 1.37(a),
relating to recordkeeping requirements .  MLF agreed  to cease and desist from
violating Section 4c(a)(A) of the Act and Regulation 1.37(a), and to pay a civil
monetary penalty of $175,000.
