Note 1.
ORGANIZATION



| | A. | General Description of the Trust
| | -- | --------------------------------

The statement of
financial condition, including the condensed schedule of investments, as of June 30, 2006, the statements of operations for the three months and six months ended June 30, 2006 and 2005, and the statements of changes in trust capital for
the six months ended June 30, 2006 and 2005 are unaudited. The December 31, 2005 references were taken from audited financial statements. In the opinion of Preferred Investment Solutions Corp. (Preferred or Managing
Owner), the financial statements contain all adjustments (consisting of only normal recurring adjustments) necessary to state fairly the financial position of Diversified Futures Trust I (the Trust) as of June 30, 2006 and the
results of its operations for the three months and six months ended June 30, 2006 and 2005. The operating results for the interim periods may not be indicative of the results expected for the full year.

Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with accounting principles generally
accepted in the United States of America have been omitted. It is suggested that these financial statements be read in conjunction with the financial statements and notes thereto included in the Trusts annual report on Form 10-K filed with the
Securities and Exchange Commission for the year ended December 31, 2005.

The Trust was organized under the Delaware Statutory Trust
Act on May 18, 1994 and will continue until December 31, 2020 unless terminated sooner under the provisions of the Second Amended and Restated Declaration of Trust and Trust Agreement (the Trust Agreement). The Trust was formed
to engage in the speculative trading of commodity futures and forward contracts. The Trusts trustee is Wilmington Trust Company.

Note 2. RELATED PARTIES

The Managing Owner or third parties engaged by the Managing Owner perform
services for the Trust which include, but are not limited to: brokerage services; accounting and financial management; registrar, transfer and assignment function; investor communications; printing and other administrative services. Except for costs
related to brokerage services, Preferred pays all the costs of these services as well as the Trusts routine operational, administrative, legal and auditing costs.

The costs charged to the Trust for brokerage commissions for the six months ended June 30, 2006 and 2005 were $631,923 and $707,603, respectively, and for the three months ended June 30, 2006 and 2005 were
$307,973 and $342,864, respectively.

The Trusts assets are maintained either in trading or cash accounts at the Trusts
commodity broker, or for margin purposes, with the various exchanges on which the Trust is permitted to trade. The broker credits the Trust monthly with 100% of the interest it earns on the average net assets in the Trusts accounts.

Note 3. DERIVATIVE INSTRUMENTS AND ASSOCIATED RISKS

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

Note 3.
DERIVATIVE INSTRUMENTS AND ASSOCIATED RISKS (CONTINUED)

Market Risk

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

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

Credit Risk

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

Note 3.
DERIVATIVE INSTRUMENTS AND ASSOCIATED RISKS (CONTINUED)

Credit Risk (Continued)

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

The Trusts futures commission merchant in accepting orders for the purchase or sale of domestic futures contracts, is required by Commodity Futures
Trading Commission (CFTC) regulations to separately account for and segregate as belonging to the Trust all assets of the Trust relating to domestic futures trading and is not to commingle such assets with its other assets. At
June 30, 2006 and December 31, 2005, such segregated assets totaled $9,053,248 and $8,829,027, respectively. Part 30.7 of the CFTC regulations also requires the Trusts futures commission merchant to secure assets of the Trust related
to foreign futures trading which totaled $6,514,491 and $340,601 at June 30, 2006 and December 31, 2005, respectively. There are no segregation requirements for assets related to forward trading.

As of June 30, 2006, substantially all of the Trusts open futures and forward contracts mature within eighteen months.

DIVERSIFIED FUTURES TRUST I

(a Delaware Business Trust)



|ITEM 2. | MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
|------- | -------------------------------------------------------------------------------------

This Report includes forward-looking statements that reflect Preferred Investment Solutions Corps. (the Managing Owner) current expectations about the future results, performance, prospects and
opportunities of Diversified Futures Trust I (the Trust ). The Managing Owner has tried to identify these forward-looking statements by using words such as may, will, expect, anticipate,
believe, intend, should, estimate or the negative of those terms or similar expressions. These forward-looking statements are based on information currently available to the Managing Owner and are
subject to a number of risks, uncertainties and other factors, both known, such as those described in this Report, and unknown, that could cause the Trusts actual results, performance, prospects or opportunities to differ materially from those
expressed in, or implied by, these forward-looking statements.

You should not place undue reliance on any forward-looking statements. Except as expressly
required by the Federal securities laws, the Managing Owner undertakes no obligation to publicly update or revise any forward-looking statements or the risks, uncertainties or other factors described in this Report, as a result of new information,
future events or changed circumstances or for any other reason after the date of this Report.

Critical Accounting Policies

Preparation of the financial statements and related disclosures in compliance with accounting principles generally accepted in the United States of America requires the
application of appropriate accounting rules and guidance, as well as the use of estimates. The Trusts application of these policies involves judgments and actual results may differ from the estimates used.

The Managing Owner has evaluated the nature and types of estimates that it makes in preparing the Trusts financial statements and related disclosures and has
determined that the valuation of its investments which are not traded on a United States or Internationally recognized futures exchange involves a critical accounting policy. The market values of futures (exchange traded) contracts is verified by
the administrator who obtains valuation data from third party data providers such as Bloomberg and Reuters and compares those prices with the Trusts broker. The market value of currency swap and forward (non-exchange traded) contracts is
extrapolated on a forward basis from the spot prices quoted as of 3 PM on the last business day of the reporting period. All values assigned by the administrator and confirmed by the Managing Owner are final and conclusive as to all Interest
holders.

As such, if actual results vary from estimates used, they are anticipated to not have a material impact on the financial statements and related
disclosures.

Liquidity and Capital Resources

The
Trust commenced operations on January 5, 1995 with gross proceeds of $25,262,800 allocated to commodities trading. The Trust continued to offer interests on a monthly basis until the continuous offering period ended on August 31, 1996,
resulting in additional gross proceeds to the Trust of $41,129,100.

The Trust Agreement provides that an Interest holder may redeem its Interests as of
the last business day of any calendar quarter at the then current NAV per Interest. Redemptions of Limited Interests and general interests for the three months and six months ended June 30, 2006 were $525,606, $0, $1,298,452 and $8,285,
respectively. Redemptions of Limited Interests and General Interests from the commencement of operations, January 5, 1995, to June 30, 2006 totaled $84,866,678 and $713,430, respectively. Future redemptions will impact the amount of funds
available for investment in commodity contracts in subsequent periods.

At June 30, 2006, 100% of the Trusts net assets were allocated to
commodities trading. A significant portion of the net assets was held in cash which was used as margin for the Trusts trading in commodities. Inasmuch as the sole business of the Trust is to trade in commodities, the Trust continues to own
such liquid assets to be used as margin. The broker credits the Trust monthly with 100% of the interest it earns on the average net assets in these accounts.

The commodities contracts are subject to periods of illiquidity because of market conditions, regulatory considerations and other reasons. For example, commodity exchanges limit fluctuations in certain commodity futures contract prices
during a single day by regulations referred to as daily limits. During a single day, no trades may be executed at prices beyond the daily limit. Once the price of a futures contract for a particular commodity has increased or decreased
by an amount equal to the daily limit, positions in the commodity can neither be taken nor liquidated unless traders are willing to effect trades at or within the limit. Commodity futures prices have occasionally moved the daily limit for several
consecutive days with little or no trading. Such market conditions could prevent the Trust from promptly liquidating its commodity futures positions.

Since the Trusts business is to trade futures and forward contracts, its capital is at risk due to changes in the
value of these contracts (market risk) or the inability of counterparties to perform under the terms of the contracts (credit risk). The Trusts exposure to market risk is influenced by a number of factors, including the volatility of interest
rates and foreign currency exchange rates, the liquidity of the markets in which the contracts are traded and the relationships among the contracts held. The inherent uncertainty of the Trusts speculative trading, as well as the development of
drastic market occurrences could result in monthly losses considerably beyond the Trusts experience to date and could ultimately lead to a loss of all or substantially all of investors capital. The Managing Owner attempts to minimize
these risks by requiring the Trust and its trading managers to abide by various trading limitations and policies which include limiting margin amounts, trading only in liquid markets and permitting the use of stop loss provisions. See Note 3 to the
financial statements for a further discussion of the credit and market risks associated with the Trusts futures and forward contracts.

The Trust
does not have, nor does it expect to have, any capital assets.

Off-Balance Sheet Arrangements and Contractual Obligations

As of June 30, 2006, the Trust has not utilized special purpose entities to facilitate off-balance sheet financing arrangements and has no loan guarantee
arrangements or off-balance sheet arrangements of any kind other than agreements entered into in the normal course of business, which may include indemnification provisions related to certain risks service providers, such as our accountants,
undertake in performing services which are in the best interests of the Trust. While the Trusts exposure under such indemnification provisions can not be estimated, these general business indemnifications are not expected to have a material
impact on the Trusts financial position.

The Trusts contractual obligations are with the Managing Owner, each Trading Manager and its
commodity broker. Payments made under the Trusts agreement with each Trading Manager are at a fixed rate, calculated as a percentage of the Trusts New High Net Trading Profits. Management fee payments made to the Trading
Managers and fees paid to the Managing Owner are calculated as a fixed percentage of the Trusts Net Asset Values (NAVs). As such, the Managing Owner cannot anticipate the amount of payments that will be required under these
agreements for futures periods as NAVs are not known until a future date. Commission payments to the commodity broker are based on a cost per executed trade and, as such, the Managing Owner cannot anticipate the amount of payments that will be
required under the brokerage agreement for future periods as the level of executed trades are not known until a future date. These agreements are effective for one-year terms, renewable automatically for additional one-year terms unless terminated.
Additionally, these agreements may be terminated by either party for various reasons. For a further discussion on these payments, see Notes 1 and 3 of the Registrants 2005 Annual Report.

Results of Operations

The net asset value per interest as of
June 30, 2006 was $224.71 a decrease of 3.30% from the December 31, 2005 net asset value per interest of $232.38 and a decrease of 2.36% from the March 31, 2006 net asset value per interest of $230.14. Past performance is not
necessarily indicative of future results.

The Trusts trading gains (losses) before commissions were approximately $(179,000), $(116,000), $527,000
and $(540,000) during the three months and six months ended June 30, 2006 and 2005, respectively. Due to the nature of the Trusts trading activities, a period to period comparison of its trading results is not meaningful. However, a
detailed discussion of the Trusts current quarter trading results is presented below.

Second Quarter 2006 Economic Overview

News from the Federal Reserve (Fed) and its new chairman, Ben Bernanke, dominated the markets in the second quarter of 2006. Chairman Bernanke appears fully
committed to fighting inflation and has quickly eliminated speculation that he might take a softer stance than his predecessor. The Fed continued to raise rates throughout the quarter. The Fed minutes have repeatedly stated that the Federal
Open Market Committees (FOMC) actions will be data dependent and to this point that means the rate hike cycle is likely to continue at least for one addition meeting. As global liquidity and geopolitical concerns arose during the
second quarter, U.S. Treasury yields found safe haven support.

Inflation and housing were again the major factors within the U.S. economic landscape. As
gasoline prices continued to rise, inflation data drew particular attention. The housing market was somewhat mixed and the outlook remains uncertain. Despite these factors, final first quarter Gross Domestic Product (GDP) was revised
upwards to 5.3% from the original 4.6%. However, the impact of a weaker housing sector and high gasoline and energy prices may be starting to take a toll, as the preliminary GDP for the second quarter was lower than expected at 2.5%.

The Eurozone continued to experience economic improvement in the second quarter. However, like the U.S., the third quarter may present a somewhat less buoyant
picture. The euro turned in a strong quarter benefiting from central bank currency diversification. Interest rates were a primary focus as the European Central Bank (ECB) hiked rates by 25 basis points to 2.75% at its June meeting with
further increases anticipated later in the year. An ongoing pattern of improved economic data was noted, particularly from Germany. In the U.K., the Bank of England (BOE) made no rate changes; economic data was fairly decent but
showed some strain as the third quarter began.

In Japan, speculation that the Bank of Japan (BOJ) would finally end its zero interest
rate policy proved correct as they imposed a 0.25% rate during the first week of July. Japan was at the forefront of the short-lived liquidity crisis, which instigated a sell-off in global assets during the second quarter, and their
equity market fell approximately 9%. Other Asian equity markets saw a similar fate with Korea, Hong Kong and Shanghai also experiencing weakness. Despite the temporary disruption,

---

overall economic data from Japan, and the region in general, showed an improved tone. Chinas growth continues to be strong, as second quarter GDP rose
to a 10 year high of 11.2%. The Bank of China raised interest rates in April in an attempt to harness growth and its inflationary implications. Further rate hikes are expected.

The Canadian economy has been moving at a brisk pace all year and the Bank of Canada has steadily raised rates. However, the statement at the conclusion of its most recent meeting suggests that a pause may be on the
horizon. The Canadian dollar strengthened in the second quarter of 2006 and Canadas economic fortunes seem bright.

Currencies

Interest rates were the primary drivers of the currency sector in the second quarter of 2006. The U.S. dollar suffered against the euro as the ECB appears to be at the
beginning of its rate hike cycle and the Fed appears to be close to the end. Additionally, a continued pattern of improving economic data in the Eurozone was noted throughout the quarter, particularly from Germany, the leading driver of
the regions growth. The euro also benefited from central bank currency diversification away from the U.S. dollar as the global reserve currency, as Russia, China, Sweden, and the United Arab Emirates were prominent in this trend, which is
expected to continue. Despite this pressure, the U.S. dollar attracted flight to safety support in mid June when the Korean missile crisis emerged.

In Japan, the focus was also on interest rates, as market participants attempted to discern when the BOJ would end its long standing zero interest rate policy. The BOJ drained liquidity throughout the quarter in preparation for
this eventuality. The Japanese economy continues to improve, as highlighted by one of the most watched economic indicators, the Tankan Report, which was released at the end of June and the second quarter saw the definitive conclusion of the
nations deflationary era. The yen was pressured a bit in late June by the scandal surrounding BOJ Governor Fukui.

The Chinese yuan traded at 7.999
to the U.S. dollar in late June compared to 8.017 at the end of the first quarter and has gained slightly over 1% since its 2.1% revaluation in July 2005. Recent comments from Bank of China officials have hinted at a potentially faster pace, but the
markets have lent little credence to this statement.

Energies

The energy sector was volatile in the second quarter of 2006. Crude ended the quarter around $74 per barrel, up approximately 8.5% from the end of the previous quarter. Geopolitical uncertainty regarding Iran, North Korea and Nigeria were
supportive of crude. Additional support is coming from increased demand from China and India. The price at the pump for unleaded gasoline remains high, but demand continued to display a relatively inelastic pattern. The only component of the sector
that fell was natural gas. With plenty of supply, moderate temperatures and a slow start to the hurricane season, prices of natural gas continued their downward slide.

Grains

The sector was mixed for the quarter. On the production side of the equation, weather played the single
largest role in corn prices for the second quarter. On a week-by-week basis, as chances for seasonally beneficial precipitation ebbed and flowed, corn prices moved higher and lower respectively. The start of the period found the corn market firmly
ensconced in an uptrend that began at the end of calendar year 2005, but prices fell off sharply in June after the release of a U.S. Department of Agriculture (USDA) Supply/Demand Report that raised questions about the demand for corn.
The decline in corn prices, along with many other commodity markets, may have had its roots in a consumption-restricting announcement made by the Chinese government. The statement made was that internal growth needed to be slowed, in light of a
too-rapidly expanding economy. The graphic profile of the wheat market is almost identical as that seen in corn. For most of the second quarter, soybean prices moved sideways. Due to Chinas dependence on Brazilian soybean imports, the
tightening credit situation in China will likely not have as great a bearing on U.S. soybean prices.

Indices

By and large, global equity indices were lower in the second quarter of 2006 versus the first quarter of 2006. For most of the quarter, U.S. stocks suffered from the
uncertainty surrounding the interest rate environment and from fears that the U.S. economy was slowing, mainly due to higher energy prices and a softer housing sector. The S&P 500 ended the quarter down 1.9% and the NASDAQ ended the quarter down
7.2%. Going forward U.S. equities are likely to remain highly sensitive to any events that might alter the outlook for the Fed, particularly inflation related data.

European markets had been strong for most of the year prior to the sell-off in May. Foreign money flows into Europe slowed significantly in May and were still at a somewhat reduced level in June. The German DAX ended
the quarter down 4.8%, the French CAC 40 was down 4.9% and the British FTSE was down 2.2%.

Asian markets were very volatile, particularly in May and
June, as a liquidity crunch was experienced in Japan and in various other sectors around the region. Indications of higher interest rates in Japan, Korea and China in coming months provided a negative tone, but the flow of economic data
took on a positive tone and bodes well for the rest of the year. Japans Nikkei was down 9.1% for the quarter and Koreas Kospi was down 4.7%. Australias All Ordinaries closed out the quarter down approximately 1%, but the strength
in resource issues aided this market and the outlook for Australia is positive.

Interest Rates

U.S. Treasuries were in a rally mode for much of May and June as the markets evaluated the new Fed under Ben Bernanke. The FOMC appeared to be taking on a more
aggressively anti-inflationary tone as the quarter progressed, with the Chairman and numerous Fed Governors focusing on the threat of inflation. After closing out the first quarter at 4.85%, the yield on the 10-year Treasury Note moved
over 5.26% in mid June on the market view that that the Fed would continue to raise rates through the August meeting and possibly beyond. The softer tone of the statement accompanying the 25 basis point rate hike

---

at the end of June caught the markets by surprise. While still recognizing the risk of inflation, the Fed gave greater credence to the potential for some
economic slowing, and appeared to put into question the prospect of a further rate hike in August. As June concluded, the yield on the 10-year Treasury Note stood at 5.145%.

Outside of the U.S., the ECB raised rates 25 basis points in June to 2.75%. Statements by ECB President Jean Claude Trichet regarding inflation were mixed throughout the quarter, but were leaning towards the
tightening side as June ended and additional ECB rate hikes are expected later this summer. Trichet has emphasized that inflation will remain elevated and that there is a risk of a surge in consumer prices. European data, particularly from Germany
remains buoyant. The 10-year German Bund was yielding 4.07% at the end of June while the 30-year stood at 4.31%.

In the first week of July, the BOJ
officially ended its zero interest rate policy by imposing a 0.25% rate, finally putting an end to the speculation that was rampant throughout the second quarter. Other Asian banks, including the Bank of Korea, raised rates in June and
there are growing indications that the Bank of China will embark on a tightening bias to temper the expected 10% plus GDP growth and its inflationary potential. The Bank of Canada raised rates another 25 basis points but the accompanying statement
hinted at a pause. The Reserve Bank of Australia held rates at 5.75% but there is speculation of an increase.

Metals

Gold had been in an upside surge for the entire year until things finally came to an end, at least temporarily, in late May. Global liquidity tightness, particularly in
the Far East, which impacted other commodities as well as the equity and fixed income markets, served as a clear negative for gold and essentially put an end to the rally. Geopolitical concerns surrounding Iran, Iraq and Korea have been
supportive for gold and are likely to aid the bull case in coming weeks. In addition, reserve asset diversification is likely to persist. Russia, China and Sweden, along with the United Arab Emirates and other petro-nations were active in that
regard during the second quarter. Petrodollars have been flowing into gold for much of the year, although that slowed somewhat in June. Silver followed a similar pattern to gold, retaining its dependent relationship with the yellow metal.

The entire base metal complex was very volatile during the second quarter. Copper ended the quarter up 37% from the previous quarter, as labor and
production problems in Mexico, Chile and Zambia added to the bullish scenario. With China forecast to see 10% plus GDP growth in 2006, the demand side of the equation still looks strong, as it does for most of Asia as well as the U.S. and
Europe. Mines still lack the ability to significantly ramp up production, giving copper a solid fundamental base. After surging nearly 17% in May, zinc lost 15% in June but it is still up more than 75% for the year. Fundamentally, zinc presents
the strongest picture among all the base metals as it faces a significant production deficit. Nickel rallied strongly for the quarter as well. While its fundamentals have improved, as stainless steel demand increased, the recent highs are vastly
ahead of reasonable value.

Softs

The sector was mixed
for the second quarter, with several markets experiencing significant sell-offs in May. Sugar had been extremely firm in the first quarter through mid second quarter, before undergoing a correction in May. Following a weak performance in May,
which saw sugar decline over 11%, prices rebounded in June. However, the outlook is uncertain, as the weather in Brazils sugar producing areas has been crop friendly after a period of dry conditions. Coffee prices also fell in May,
losing 10%. Brazilian weather has been excellent, which weighed on sentiment throughout the second quarter. The harvest has been moving at a brisk pace and at 35% complete for the season, is ahead of schedule. The second quarter saw cocoa
prices trend higher. The Ivory Coast was the focus after the disarmament process broke down yet again. Cattle scored gains in May and June as the USDA announced an agreement with Japan to restart U.S. beef exports to that nation. Hogs also
put in a strong June, as Far Eastern demand remained brisk.

Currencies: (-)Long positions in the euro and the British pound, short positions in
the Swiss franc, and long and short positions in both the Australian dollar and the Japanese yen were the largest contributors to the loss in the second quarter of 2006.

Energies: (-) Losses experienced on long positions in Brent crude, crude oil, heating oil, and unleaded gas, as well as long and short positions in natural gas, resulted in a loss for the second quarter of
2006.

Grains: (-)The sector was down for the second quarter of 2006, with a majority of the losses from long and short positions in corn and
wheat, as well as short positions in soybean meal.

Indices: (-) Long positions in the FTSE 100 and the IBEX 35, and long and short positions in the
NASDAQ, the Japanese Nikkei and the S&P 500, contributed to losses in the second quarter.

Interest Rates: (+)The interest rate
sector was up for the second quarter of 2006. Short positions in the German Bund, Eurodollar, British Gilt and Short Sterling led to the sectors profits for the quarter.

Metals: (+) The metals sector was positive for the second quarter of 2006, with long positions in gold, copper, aluminum, nickel, zinc and silver providing the largest profits.

Softs: (-)The sector was negative for the second quarter of 2006 primarily due to short positions in cocoa, live cattle and live hogs, and long and short
positions in sugar.

The Trusts average net assets have declined for the three and sixth month periods ending June 30, 2006
compared to the three and sixth month periods ending June 30, 2005 due to the effect of redemptions during 2005 and Year-to-Date 2006, offset in part by positive trading performance between July 1, 2005 and June 30, 2006.

Interest income is earned on the average net assets held at the broker and, therefore, varies monthly according to interest rates, as well as the effect of trading
performance, and redemptions. Interest income increased by approximately $60,000 and $126,000 for the three months and six months ended June 30, 2006 respectively, as compared to the corresponding periods in 2005. The increase was primarily due
to higher interest rates during the First and Second Quarter of 2006 versus 2005.

Brokerage commissions are calculated on the Trusts net asset value
at the beginning of each month and, therefore, vary monthly according to trading performance and redemptions. Brokerage commissions decreased by approximately $35,000 and $76,000 for the three months and six months ended June 30, 2006
respectively, as compared to the corresponding periods in 2005. The decrease in 2006 versus 2005 was due to decreases in average net asset levels as discussed above.

Management fees are calculated on the Trusts net asset value at the end of each month and, therefore, are affected by trading performance and redemptions. Management fees for the three months and six months
ended June 30, 2006 decreased approximately $10,000 and $18,000 respectively, due to decreases in average net asset levels as discussed above.

Incentive fees are based on the New High Net Trading Profits generated by the Trading Managers, as defined in the Advisory Agreements among the Trust, the Managing Owner and the Trading Managers. No incentive fees were earned for the three
months and six months ended June 30, 2006 and June 30, 2005.

|ITEM 4. | CONTROLS AND PROCEDURES
|------- | -----------------------

As of the end of the period covered by
this report, the Managing Owner carried out an evaluation, under the supervision and with the participation of the officers of the Managing Owner, including the Managing Owners co-chief executive officer, chief financial officer and director
of fund administration, of the effectiveness of the design and operation of the Trusts disclosure controls and procedures. Based upon that evaluation, the Managing Owners co-chief executive officer, chief financial officer and director
of fund administration concluded that the Trusts disclosure controls and procedures are effective.

In designing and evaluating the Trusts
disclosure controls and procedures (as defined in Rules 13a-15(e) or 15d-15(e) of the Exchange Act), the Managing Owner recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurances of
achieving the desired control objectives, as ours are designed to do, and the Managing Owner necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures. We believe that our
disclosure controls and procedures provide such reasonable assurance.

There have not been any changes in our internal controls over financial reporting
(as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended) during the fiscal quarter to which this report relates that have materially affected, or are reasonably likely to materially affect, our internal
