-------------
As of April 1, 1997, the Net Asset Value of a Series A Unit initially
issued for $100 as of October 12, 1994 had risen to $126.69 (adding back to Net
Asset Value aggregate distributions of $12.00 per Series A Unit).
-------------
The allocation of the Fund's trading assets (75% of the capital initially
attributable to each series of Units sold pursuant to this Prospectus Supplement
and thereafter) among its core Advisors as of April 1, 1997 is set forth below
in the parentheses following each core Advisor's name. The accompanying
Prospectus includes more detailed information concerning the core Advisors.
See "The Advisors" and "The Core Advisors" in the Prospectus. Core Advisors are
Advisors allocated 10% or more of the Fund's trading assets for management. Non-
core Advisors are each allocated less than 10% of the Fund's assets for
management. The particular percentage allocations to the non-core Advisors are
not identified because, among other things, these allocations are subject to
frequent changes both due to the effects of differential performance and to
Merrill Lynch Investment Partners Inc. reallocating the Fund's traded assets
among such Advisors.

PAST PERFORMANCE IS NOT NECESSARILY INDICATIVE OF FUTURE RESULTS.
Performance and assets under management information is current as of March 31,
1997.
Performance figures are not audited.
Futures trading is highly leveraged, as is each Advisor's trading program.
No Advisor has been asked to make any special adjustments to its leveraging
policies in the case of the Fund. See "Leverage Considerations" and "Risk
Factors" in the Prospectus.
In considering the leverage at which the different Advisors trade and the
volatility of their performance, prospective investors should recognize that due
to the limited percentage of the Fund's trading assets allocated to each of
them, none of the non-core Advisors, individually, is likely to have a material
effect, over the short-term, on either the overall return or the overall
performance volatility of the Fund. The non-core Advisors as a group can have a
significant effect on performance. However, the likely performance non-
correlation among at least certain of these Advisors reduces the likelihood of
any major short-term effect.
The current non-core Advisors each receive Consulting Fees of up to 2% per
annum of the Fund's assets managed by each of them, respectively, plus quarterly
or annual Profit Shares of between 15% and 20% of any cumulative New Trading
Profit achieved by each such Advisor.
- ----------
1 The lowest and the highest monthly rate of return for the program traded for
the Fund. Performance information is presented for the period from January
1, 1992 (or inception, if later) through March 31, 1997.
2 An annualized standard deviation of 2% and a mean return of 1% would mean
that approximately two-thirds of all monthly returns during a year have
historically fallen between (1)% and 3%, i.e., within a range (deviation) of
2% above or below the mean. Standard deviation is one widely-accepted measure
of risk, as standard deviation indicates the variability of returns. In
general, the more variable an Advisor's historical returns, the greater the
risk that substantial losses have been included within the historical range
of returns.
3 Assets under management in the program traded for the Fund ("notional" funds
excluded, except as described in Note (6) below).
4 See "The Core Advisors" in the Prospectus for a description of these strategy
classifications.
5 The worst Monthly Rate of Return of any individual account, not of the
program on a composite basis.
6 "Notional" funds are included in assets under management for Quantitative
Financial Strategies, Inc.
