CAMPBELL ALTERNATIVE ASSET TRUST
NOTES TO FINANCIAL STATEMENTS
(Unaudited)

Note 1.ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

A.	General Description of the Trust
	Campbell Alternative Asset Trust (the Trust) is a Delaware statutory trust which operates as a commodity investment pool. The Trust was formed on May 3, 2000 and commenced trading on October 1, 2001. The Trust engages in the speculative trading of futures contracts, forward currency contracts and options on forward currency contracts.
	As of December 31, 2002, units are no longer offered to the public, but are offered exclusively for sale to the Campbell & Company, Inc. 401(K) Plan (the 401(K) Plan). At June 30, 2006, the 401(K) Plan held approximately 49.05% of the Trust’s outstanding units.
B.	Regulation
	As a registrant with the Securities and Exchange Commission, the Trust is subject to the regulatory requirements under the Securities Act of 1933 and the Securities Exchange Act of 1934. As a commodity investment pool, the Trust is subject to the regulations of the Commodity Futures Trading Commission, an agency of the United States (U.S.) government which regulates most aspects of the commodity futures industry; rules of the National Futures Association, an industry self-regulatory organization; and the requirements of the various commodity exchanges where the Trust executes transactions. Additionally, the Trust is subject to the requirements of futures commission merchants (brokers) and interbank market makers through which the Trust trades.
C.	Method of Reporting
	The Trust’s financial statements are presented in accordance with accounting principles generally accepted in the United States of America, which may require the use of certain estimates made by the Trust’s management. Actual results may differ from these estimates. Investment transactions are accounted for on the trade date. Gains or losses are realized when contracts are liquidated. Unrealized gains and losses on open contracts (the difference between contract trade price and market price) are reported in the statement of financial condition as a net gain or loss, as there exists a right of offset of unrealized gains or losses in accordance with Financial Accounting Standards Board Interpretation No. 39 – “Offsetting of Amounts Related to Certain Contracts.” The market value of futures (exchange-traded) contracts is determined by the various futures exchanges, and reflects the settlement price for each contract as of the close of the last business day of the reporting period. The market value of swap and forward currency (non-exchange traded) contracts is extrapolated on a forward basis from the spot prices quoted as of 5:00 P.M. (E.T.) of the last business day of the reporting period or based on the market value of its exchange-traded equivalent. The market value of option (non-exchange traded) contracts is calculated by applying an industry-standard adaptation of the Black-Scholes options valuation model to foreign currency options, using as input, the spot prices, interest rates and option implied volatilities quoted as of 3:00 P.M. (E.T.) on the last business day of the reporting period. Any change in net unrealized gain or loss from the preceding period is reported in the statement of operations. Brokerage commissions include other trading fees and are charged to expense when contracts are opened. United States government securities are stated at cost plus accrued interest, which approximates market value.

CAMPBELL ALTERNATIVE ASSET TRUST
NOTES TO FINANCIAL STATEMENTS (CONTINUED)
(Unaudited)

Note 1.ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

C.	Method of Reporting (Continued)
	For purposes of both financial reporting and calculation of redemption value, Net Asset Value per unit is calculated by dividing Net Asset Value by the number of outstanding units.
D.	Income Taxes
	The Trust prepares calendar year U.S. and applicable state information tax returns and reports to the unitholders their allocable shares of the Trust’s income, expenses and trading gains or losses. No provision for income taxes has been made in the accompanying financial statements as each unitholder is individually responsible for reporting income or loss based on such unitholder’s respective share of the Trust’s income and expenses as reported for income tax purposes.
E.	Offering Costs
	Campbell & Company, Inc. (Campbell & Company) has incurred all costs in connection with the initial and continuous offering of units of the Trust (offering costs). Offering costs are charged to the Trust at a monthly rate of 1/12 of 0.9% (0.9% annualized) of the Trust’s month-end net asset value (as defined in the Amended and Restated Declaration of Trust and Trust Agreement) until such amounts are fully reimbursed. Such amounts are charged directly to unitholders’ capital. The Trust is only liable for payment of offering costs on a monthly basis. At June 30, 2006 and December 31, 2005, the Trust reflects a liability in the statement of financial condition for offering costs payable to Campbell & Company of $15,764 and $16,208, respectively.
	The offering costs for which Campbell & Company are being reimbursed relate to the offering of units of the Trust to all unitholders except the 401(K) Plan. Therefore, Campbell & Company rebates to the 401(K) Plan the offering costs charged to the 401(K) Plan. All such rebates are made by issuing additional units to the 401(K) Plan.
	If the Trust terminates prior to completion of payment to Campbell & Company for the unreimbursed offering costs incurred through the date of such termination, Campbell & Company will not be entitled to any additional payments, and the Trust will have no further obligation to Campbell & Company. At June 30, 2006 and December 31, 2005, the amount of unreimbursed offering costs incurred by Campbell & Company is $495,169 and $592,663, respectively.
F.	Foreign Currency Transactions
	The Trust’s functional currency is the U.S. dollar; however, it transacts business in currencies other than the U.S. dollar. Assets and liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the rates in effect at the date of the statement of financial condition. Income and expense items denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the rates in effect during the period. Gains and losses resulting from the translation to U.S. dollars are reported in income.

From the 2.85% fee, a portion (0.35%) is used to compensate selling agents for administrative services and a portion (2.5%) is retained by Campbell & Company for trading and management services rendered.

Campbell & Company is also paid a performance fee equal to 20% of New Appreciation (as defined) calculated as of the end of each calendar quarter and upon redemption of units.

The Trust is exposed to both market risk, the risk arising from changes in the market value of the contracts, and credit risk, the risk of failure by another party to perform according to the terms of a contract.

Purchase and sale of futures contracts requires margin deposits with the broker. Additional deposits may be necessary for any loss on contract value. The Commodity Exchange Act requires a broker to segregate all customer transactions and assets from such broker’s proprietary activities. A customer’s cash and other property (for example, U.S. Treasury bills) deposited with a broker are considered commingled with all other customer funds subject to the broker’s segregation requirements. In the event of a broker’s insolvency, recovery may be limited to a pro rata share of segregated funds available. It is possible that the recovered amount could be less than total cash and other property deposited.

The amount of required margin and good faith deposits with the broker and interbank market makers usually range from 10% to 30% of Net Asset Value. The market value of securities held to satisfy such requirements at June 30, 2006 and December 31, 2005 was $36,000,424 and $29,830,276, respectively, which equals approximately 88% and 75% of Net Asset Value, respectively. The cash deposited with interbank market makers at June 30, 2006 and December 31, 2005 was $2,015,618 and $8,987,245, respectively, which equals approximately 5% and 23% of Net Asset Value, respectively. Included in cash deposits with interbank market makers at December 31, 2005 was restricted cash for margin requirements of $1,873,271 which equals approximately 5% of Net Asset Value at December 31, 2005. There was no restricted cash as of June 30, 2006.

The Trust trades forward currency and options on forward currency contracts in unregulated markets between principals and assumes the risk of loss from counterparty nonperformance. Accordingly, the risks associated with forward currency and options on forward currency contracts are generally greater than those associated with exchange traded contracts because of the greater risk of counterparty default. Additionally, the trading of forward currency and options on forward currency contracts typically involves delayed cash settlement.

The Trust has a substantial portion of its assets on deposit with financial institutions. In the event of a financial institution’s insolvency, recovery of Trust assets on deposit may be limited to account insurance or other protection afforded such deposits.

Note 7.TRADING ACTIVITIES AND RELATED RISKS (CONTINUED)

For derivatives, risks arise from changes in the market value of the contracts. Theoretically, the Trust is exposed to a market risk equal to the notional contract value of futures, forward currency and swap contracts purchased and unlimited liability on such contracts sold short. As a seller of options, the Trust receives a premium at the outset and then bears the risk of unfavorable changes in the price of the contract underlying the option. Written options expose the Trust to potentially unlimited liability.

The unrealized gain (loss) on open futures, forward currency and options on forward currency contracts is comprised of the following:

	Futures Contracts						Forward Currency and Options on Forward
	(exchange traded)						Currency Contracts (non-exchange traded)
	June 30,			December 31,			June 30,			December 31,
	2006			2005			2006			2005
Gross unrealized gains	$	658,673		$	537,098		$	1,507,312		$	1,046,611
Gross unrealized losses		(225,364	)		(697,758	)		(1,871,983	)		(2,371,475	)
Net unrealized gain (loss)	$	433,309		$	(160,660	)	$	(364,671	)	$	(1,324,864	)

Open contracts generally mature within three months; as of June 30, 2006, the latest maturity date for open futures contracts is March 2007, and the latest maturity date for open forward currency contracts is September 2006. However, the Trust intends to close all contracts prior to maturity.

Campbell & Company has established procedures to actively monitor market risk and minimize credit risk, although there can be no assurance that it will, in fact, succeed in doing so. Campbell & Company’s basic market risk control procedures consist of continuously monitoring open positions, diversification of the portfolio and maintenance of a margin-to-equity ratio that rarely exceeds 30%. Campbell & Company seeks to minimize credit risk primarily by depositing and maintaining the Trust’s assets at financial institutions and brokers which Campbell & Company believes to be creditworthy. The unitholders bear the risk of loss only to the extent of the market value of their respective investments and, in certain specific circumstances, distributions and redemptions received.

Note 8.INDEMNIFICATIONS

In the normal course of business, the Trust enters into contracts and agreements that contain a variety of representations and warranties and which provide general indemnifications. The Trust’s maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Trust that have not yet occurred. The Trust expects the risk of any future obligation under these indemnifications to be remote.

Item 2.Management’s Discussion and Analysis of Financial Condition andResults of Operations

Introduction

The offering of Campbell Alternative Asset Trust’s (the “Trust”) Units of Beneficial Interest commenced on May 15, 2001, and the initial offering terminated on September 30, 2001 with proceeds of $15,821,743. The continuing offering period commenced immediately after the termination of the initial offering period; additional subscriptions totaling $30,811,592 have been accepted during the continuing offering period as of June 30, 2006. Redemptions over the same time period total $23,022,720. The Trust commenced operations on October 1, 2001.

As of December 31, 2002, units are no longer offered to the public, but are offered exclusively for sale to the Campbell & Company, Inc. 401(K) Plan.

Critical Accounting Policies

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and expense during the reporting period. Management believes that the estimates utilized in preparing the financial statements are reasonable and prudent; however, actual results could differ from those estimates. The Trust’s significant accounting policies are described in detail in Note 1 of the Financial Statements.

The Trust records all investments at fair value in its financial statements, with changes in fair value reported as a component of realized and change in unrealized trading gain (loss) in the Statements of Operations. Generally, fair values are based on market prices; however, in certain circumstances, estimates are involved in determining fair value in the absence of an active market closing price (e.g. forward contracts which are traded in the inter-bank market).

Capital Resources

The Trust will raise additional capital only through the sale of Units offered pursuant to the continuing offering, and does not intend to raise any capital through borrowing. Due to the nature of the Trust’s business, it will make no capital expenditures and will have no capital assets which are not operating capital or assets.

Liquidity

Most United States commodity exchanges limit fluctuations in futures contracts prices during a single day by regulations referred to as “daily price fluctuation limits” or “daily limits.” During a single trading day, no trades may be executed at prices beyond the daily limit. Once the price of a futures contract has reached the daily limit for that day, positions in that contract can neither be taken nor liquidated. Futures prices have occasionally moved the daily limit for several consecutive days with little or no trading. Similar occurrences could prevent the Trust from promptly liquidating unfavorable positions and subject the Trust to substantial losses which could exceed the margin initially committed to such trades. In addition, even if futures prices have not moved the daily limit, the Trust may not be able to execute futures trades at favorable prices if little trading in such contracts

- 16 -

is taking place. Other than these limitations on liquidity, which are inherent in the Trust’s futures trading operations, the Trust’s assets are expected to be highly liquid.

The entire offering proceeds, without deductions, will be credited to the Trust’s bank and brokerage accounts to engage in trading activities and as reserves for that trading. The Trust meets its margin requirements by depositing U.S. government securities with the futures broker and the over-the-counter counterparties. In this way, substantially all (i.e., 95% or more) of the Trust’s assets, whether used as margin for trading purposes or as reserves for such trading, can be invested in U.S. government securities and time deposits with U.S. banks. Investors should note that maintenance of the Trust’s assets in U.S. government securities and banks does not reduce the risk of loss from trading futures and forward contracts. The Trust receives all interest earned on its assets. No other person shall receive any interest or other economic benefits from the deposit of Trust assets.

Approximately 10% to 30% of the Trust’s assets normally are committed as required margin for futures contracts and held by the futures broker, although the amount committed may vary significantly. Such assets are maintained in the form of cash or U.S. Treasury bills in segregated accounts with the futures broker pursuant to the Commodity Exchange Act and regulations thereunder. Approximately 10% to 30% of the Trust’s assets are deposited with over-the-counter counterparties in order to initiate and maintain forward contracts. Such assets are not held in segregation or otherwise regulated under the Commodity Exchange Act, unless such over-the-counter counterparty is registered as a futures commission merchant. These assets are held either in U.S. government securities or short-term time deposits with U.S.-regulated bank affiliates of the over-the-counter counterparties. The remaining 40% to 80% of the Trust’s assets will normally be invested in cash equivalents, such as U.S. Treasury bills, and held by the futures broker or the over-the-counter counterparties.

The Trust’s assets are not and will not be, directly or indirectly, commingled with the property of any other person in violation of law or invested with or loaned to Campbell & Company or any affiliated entities.

Results of Operations

The returns for the six months ending June 30, 2006 and 2005 were (0.77)% and 9.40%, respectively.

2006

Of the 2006 year-to-date decrease of 0.77%, approximately 0.04% was due to trading gains (before commissions) and approximately 2.24% was due to interest income, offset by approximately 3.05% due to brokerage fees, performance fees and operating cost and offering costs borne by the Trust. An analysis of the 0.04% trading gains by sector is as follows:

- 17 -

Sector	% Gain (Loss)
Interest Rates		2.57	%
Metals		2.16
Stock Indices		0.95
Energy		0.90
Currencies		(6.54	)
		0.04	%

The Trust began the year with gains in each sector during January. The stock indices sector was the best performing sector for the month as prices rallied back from a mid-month sell off and continued the up-trend which began in late 2005. The energy markets were volatile but profitable as losses in natural gas were more than offset by gains in the crude oil complex. Industrial and precious metals prices also rose in January, contributing solid gains to the Trust’s portfolios. The long end of the U.S. yield curve reversed sharply mid-month, resulting in losses as the interest rate markets tried to assimilate conflicting economic data and the change in Federal Reserve leadership. The continued weakening of the U.S. Dollar also resulted in losses, but was offset by gains earned on non-U.S. Dollar positions.

Performance for the Trust was negative in February reversing most of the gains earned in January. Prices for crude oil and natural gas fell sharply in February as inventory build-ups weighed on the market in the midst of one of the mildest winters on record in the northeastern U.S. Concern over geopolitical tensions also eased somewhat. While this brought welcome relief at the gas pumps, this trend reversal caused the majority of the Trust’s losses this month. A relatively quiet month in currencies left the Trust mainly flat in this sector as the markets tried to ascertain the major central banks policy intentions for 2006. Ben Bernanke’s first official appearances as Chairman of the Fed and the reintroduction of the U.S. 30 year bond were digested by the bond markets, but the Trust did make some gains on its short-term interest rate positions. February was a volatile month for U.S. equities, but Euro stocks enjoyed another strong month, and contributed solid gains to the portfolio.

Strong performance from several sectors contributed to a positive March and positive first quarter. The biggest gains in March were in currencies, as the U.S. Dollar rallied in response to expectations of further interest rate hikes. Correspondingly, U.S. and Euro fixed income instruments had their worst quarter in several years, which benefited the Trust’s short positions. Energy prices rebounded profitably from February’s sell-off on renewed production and supply concerns, but this was not enough to restrain equity prices, and the stock indices sector also finished higher. Many of the base and precious metals again made new highs, and contributed positively to the Trust’s returns.

A sell-off in the U.S. Dollar against all the major currencies resulted in negative performance for the Trust in April. The currency sector was active throughout the month, and reacted sharply to comments by new Federal Reserve Chairman Ben Bernanke suggesting that U.S. interest rate hikes may be near an end. Concern that the U.S. Dollar may be losing its position as the world’s primary reserve currency also led to heavy selling of the U.S Dollar. The decline was exacerbated by the rally in non-U.S. Dollar currencies amid expectations that other central banks may be about to begin rate-hike campaigns. In response to the U.S. Dollar sell-off, fundamental

concerns and increasing geopolitical uncertainties, metals traded sharply higher and were profitable for the Trust. The energy markets also traded higher, pushing the price of crude oil to all-time new highs. Gains from these moves together with the continued bearish trend in fixed income and the mid-month rebound in equities prices helped to offset the Trust’s currency losses.

The Trust’s performance in May was negative as another trend reversal caused losses. Global stock indices posted steep declines, reversing much of their year-to-date gains, amid renewed fears of inflation, rising interest rates, and a growing concern about the housing slow-down. This was a reversal of a very profitable trend for the year in the equities sector and resulted in the Trust’s biggest losses for the month. The U.S. Dollar continued to slide against the major currencies through the first half of the month, though not as severely as in April. While the U.S. Dollar improved somewhat in the latter part of the month, it was not enough to recover the earlier losses. Energy prices came off their highs in response to a perceived easing of Middle East tensions resulted in losses for the Trust. The metals and interest rates sectors were positive, but not enough to offset the losses in these other sectors.

In June, volatile markets across the globe resulted in modest losses for the Trust. Markets in most sectors were choppy as traders tried to interpret the monetary policies expressed by each of the world’s major central banks. Gains made in the interest rates sector were offset by a continued reversal in commodity-related trends. The Australian Dollar was hit hard by weaker than expected economic data in the region which caused losses in the currencies sector. Expectations of slowed economic growth due to central bank policies as well as the shifting sands of geopolitical concerns continued to pressure prices and caused losses in the metals sector. The Trust had gains in the energy sector as prices moved higher in response to continuing uncertainty in Iran. In the face of these uncertainties and more, the equities sector was volatile, but ended the month relatively unchanged.

2005

Of the 2005 year-to-date increase of the 9.40%, approximately 10.49% was due to trading gains (before commissions) and approximately 1.25% was due to interest income, offset by approximately 2.34% due to brokerage fees and operating cost and offering costs borne by the Trust. An analysis of the 10.49% trading gains by sector is as follows:

Sector	% Gain (Loss)
Interest Rates		8.62	%
Currencies		3.80
Energy		1.48
Metals		0.18
Stock Indices		(3.59	)
		10.49	%

- 19 -

The late December 2004 reversal of the major trends in currencies and equities persisted into January 2005 leaving the Trust with negative performance for the month. The U.S. Dollar rallied sharply in the first week of the month and held its new levels, which produced losses in the currency sector. The post-election rally in equities gave way to selling in January, which also produced losses for the Trust. The energy sector was positive as crude oil approached $50 per barrel. The interest rate sector was also positive.

The rally in the U.S. Dollar failed early in February and the Dollar ended the month lower. However, the small gains on the Trust’s U.S. Dollar short positions were offset by losses in its non-Dollar currency pairs, resulting in losses in the currency sector overall. This was a difficult interest rate environment with different pressures observable at different points along the yield curve. Consequently, the Trust’s short-term interest rate positions were positive, but not profitable enough to offset the losses in long-term interest rates. The stock index sector was the best performing sector for the month as the equity markets reversed again and traded higher reclaiming a portion of the losses in January. Crude oil’s continued rally also contributed profits for the month.

The Trust had a small trading profit in the month of March. The gains for the month were in the interest rate sector, as both short-term and long-term positions were profitable, and in the energy sector where crude oil made a new high. The U.S. Dollar closed higher for the month, reversing a long downtrend, which caused losses for the Trust. In addition, the Trust incurred losses in its non-Dollar currency positions in March making the currency sector the worst performing sector for the first quarter. The equity index markets also reversed and ended the month lower which caused losses for the Trust.

Gains in the interest rate and currency sectors led to a positive return for April. Interest rate instruments continued the rally which began in late March. The energy sector was the worst performing sector for the month. Crude oil prices fell by almost $8 a barrel, which, combined with the related sell-off in other energy products, resulted in losses for the month. Equity indices were also negative with stock prices ending lower following sharp declines mid-month.

The Trust had a positive return in May which turned the Trust’s year-to-date return positive. The interest rate and currency sectors continued their profitability in April and May. The apparent breakdown of the EU constitutional ratification process was a key development late in the month causing investors to readjust their expectations for the Euro. The shift in favor of the U.S. Dollar topped off a six week rally that led to its highest level since before the 2004 U.S. elections which benefited the Trust’s currency positions. The Trust’s interest rate positions benefited from the U.S. 10-year Treasury yield being pushed once again below 4%.

In June, global uncertainties continued to provide profitable trends for the Trust. The U.S. Dollar was up sharply in June to new six month highs, as the Euro and Yen continued a steep six-week slide. A further flattening of the yield curve provided a profitable opportunity for the Trust’s models and the fixed income sector. Several energy markets made new all-time highs in June contributing to the Trust’s profits for the month.

Off-Balance Sheet Risk

The term “off-balance sheet risk” refers to an unrecorded potential liability that, even though it does not appear on the balance sheet, may result in future obligation or loss. The Trust trades in futures, forward, option and swap contracts and is therefore a party to financial instruments with elements of off-balance sheet market and credit risk. In entering into these contracts there exists a risk to the Trust, market risk, that such contracts may be significantly influenced by market conditions, such as interest rate volatility, resulting in such contracts being less valuable. If the markets should move against all of the futures interests positions of the Trust at the same time, and if the Trust’s trading advisor was unable to offset futures interests positions of the Trust, the Trust could lose all of its assets and the Unitholders would realize a 100% loss. Campbell & Company, Inc., the managing owner (who also acts as trading advisor), minimizes market risk through real-time monitoring of open positions, diversification of the portfolio and maintenance of a margin-to-equity ratio that rarely exceeds 30%.

In addition to market risk, in entering into futures, forward, option and swap contracts there is a credit risk that a counterparty will not be able to meet its obligations to the Trust. The counterparty for futures contracts traded in the United States and on most foreign exchanges is the clearinghouse associated with such exchange. In general, clearinghouses are backed by the corporate members of the clearinghouse 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, like some foreign exchanges, it is normally backed by a consortium of banks or other financial institutions.

In the case of forward, option and swap contracts, which are traded on the interbank market rather than on exchanges, the counterparty is generally a single bank or other financial institution, rather than a group of financial institutions; thus there may be a greater counterparty credit risk. Campbell & Company trades for the Trust only with those counterparties which it believes to be creditworthy. All positions of the Trust are valued each day on a mark-to-market basis. There can be no assurance that any clearing member, clearinghouse or other counterparty will be able to meet its obligations to the Trust.

Disclosures About Certain Trading Activities that Include Non-Exchange Traded Contracts Accounted for at Fair Value

The Trust invests in futures, forward currency and option on forward currency contracts. The market value of futures (exchange-traded) contracts is determined by the various futures exchanges, and reflects the settlement price for each contract as of the close of the last business day of the reporting period. The market value of forward (non-exchange traded) contracts is extrapolated on a forward basis from the spot prices quoted as of 5:00 P.M. (E.T.) of the last business day of the reporting period. The market value of option (non-exchange traded) contracts is calculated by applying an industry-standard adaptation of the Black-Scholes options valuation model to foreign currency options, using as input, the spot prices, interest rates and option implied volatilities quoted as of 3:00 P.M. (E.T.) on the last business day of the reporting period.

Item 3.Quantitative and Qualitative Disclosures About Market Risk

Introduction

Past Results Not Necessarily Indicative of Future Performance

      The Trust is a speculative commodity pool. The market sensitive instruments held by it are acquired for speculative trading purposes, and all or a substantial amount of the Trust’s assets are subject to the risk of trading loss. Unlike an operating company, the risk of market sensitive instruments is integral, not incidental, to the Trust’s main line of business.

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

      The Trust 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 particular future market scenario will affect performance, and the Trust’s past performance is not necessarily indicative of its future results.

Standard of Materiality

     Materiality as used in this section, “Quantitative and Qualitative Disclosures About Market Risk,” is based on an assessment of reasonably possible market movements and the potential losses caused by such movements, taking into account the leverage, and multiplier features of the Trust’s market sensitive instruments.

Quantifying the Trust’s Trading Value at Risk

Quantitative Forward-Looking Statements

     The following quantitative disclosures regarding the Trust’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 (such as the dollar amount of maintenance margin required for market risk sensitive instruments held at the end of the reporting period).

     The Trust’s risk exposure in the various market sectors traded is estimated in terms of Value at Risk (VaR). The Trust estimates VaR using a model based upon historical simulation (with a confidence level of 97.5%) which involves constructing a distribution of hypothetical daily changes in the value of a trading portfolio. The VaR model takes into account linear exposures to risks, including equity and commodity prices, interest rates, foreign exchange rates, and correlation among these variables. The hypothetical changes in portfolio value are based on daily percentage changes observed in key market indices or other market factors to which the portfolio is sensitive. The one day 97.5% confidence level of the Trust’s VaR corresponds to the negative change in portfolio value that, based on observed market risk factors, would have been exceeded once in 40 trading days or one day in 40. VaR typically does not represent the worst case outcome.

- 22 -

     The Trust uses approximately one year of daily market data and revalues its portfolio for each of the historical market moves that occurred over this time period. This generates a probability distribution of daily “simulated profit and loss” outcomes. The VaR is the 2.5 percentile of this distribution.

     The VaR for a sector represents the one day downside risk for the aggregate exposures associated with this sector. The aggregate VaR represents the VaR of the Trust’s open positions across all market sectors, and is less than the sum of the VaRs for all such market sectors due to the diversification benefit across asset classes.

     The Trust’s VaR computations are based on the risk representation of the underlying benchmark for each instrument or contract and does not distinguish between exchange and non-exchange dealer-based instruments. It is also not based on exchange and/or dealer-based maintenance margin requirements.

     VaR models, including the Trust’s, are continually evolving as trading portfolios become more diverse and modeling techniques and systems capabilities improve. Please note that the VaR model is used to numerically quantify market risk for historic reporting purposes only and is not utilized by the Trust in its daily risk management activities. Please further note that VaR as described above may not be comparable to similarly titled measures used by other entities.

     Because the business of the Trust is the speculative trading of futures, forwards and options, the composition of the Trust’s trading portfolio can change significantly over any given time period, or even within a single trading day, which could positively or negatively materially impact market risk as measured by VaR.

The Trust’s Trading Value at Risk in Different Market Sectors

     The following tables indicate the trading Value at Risk associated with the Trust’s open positions by market category as of June 30, 2006 and December 31, 2005 and the trading gains/losses by market category for the six months ended June 30, 2006 and the year ended December 31, 2005.

Material Limitations oF Value at Risk as an Assessment of Market Risk

The following limitations of VaR as an assessment of market risk should be noted:

1) Past changes in market risk factors will not always result in accurate predictions of the distributions and correlations of future market movements;

2) Changes in portfolio value caused by market movements may differ from those of the VaR model;

3) VaR results reflect past trading positions while future risk depends on future positions;

4) VaR using a one day time horizon does not fully capture the market risk of positions that cannot be liquidated or hedged within one day; and

5) The historical market risk factor data for VaR estimation may provide only limited insight into losses that could be incurred under certain unusual market movements.

VaR is not necessarily representative of historic risk nor should it be used to predict the Trust’s future financial performance or its ability to manage and monitor risk. There can be no assurance that the Trust’s actual losses on a particular day will not exceed the VaR amounts indicated or that such losses will not occur more than once in 40 trading days.

Non-Trading Risk

     The Trust 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 Trust also has non-trading market risk as a result of investing a substantial portion of its available assets in U.S. Treasury Bills. The market risk represented by these investments is immaterial.

Qualitative Disclosures Regarding Primary Trading Risk Exposures

     The following qualitative disclosures regarding the Trust’s market risk exposures — except for (i) those disclosures that are statements of historical fact and (ii) the descriptions of how the Trust 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 Trust’s primary market risk exposures as well as the strategies used and to be used by Campbell & Company for managing such exposures are subject to numerous uncertainties, contingencies and risks, any one of which could cause the actual results of the Trust’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 Trust. There can be no assurance that the Trust’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 their investment in the Trust.

     The following were the primary trading risk exposures of the Trust as of June 30, 2006, by market sector.

Currencies

     Exchange rate risk is the principal market exposure of the Trust. The Trust’s currency exposure is to exchange rate fluctuations, primarily fluctuations which disrupt the historical pricing relationships between different currencies and currency pairs. These fluctuations are influenced by interest rate changes as well as political and general economic conditions. The Trust trades in a large number of currencies, including cross-rates —i.e.,positions between two currencies other than the U.S. Dollar. Campbell & Company does not anticipate that the risk profile of the Trust’s currency sector will change significantly in the future.

Interest Rates

     Interest rate risk is a significant market exposure of the Trust. Interest rate movements directly affect the price of the sovereign bond positions held by the Trust 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 Trust’s profitability. The Trust’s primary interest rate exposure is to interest rate fluctuations in the United States and the other G-7 countries. Additionally, the Trust takes positions in the government debt of Switzerland. Campbell & Company anticipates that G-7 interest rates will remain the primary rate exposure of the Trust for the foreseeable future.

Stock Indices

     The Trust’s primary equity exposure is to equity price risk in the G-7 countries and several other countries (Hong Kong, Spain and Taiwan). The stock index futures traded by the Trust are by law limited to futures on broadly based indices. The Trust is primarily exposed to the risk of adverse price trends or static markets in the major U.S., European and Japanese indices. (Static markets would not cause major market changes but would make it difficult for the Trust to avoid being “whipsawed” into numerous small losses.)

Energy

     The Trust’s primary energy market exposure is to gas and oil price movements, often resulting from political developments and ongoing conflicts in the Middle East. Oil and gas prices can be volatile and substantial profits and losses have been and are expected to continue to be experienced in this market.

Metals

     The Trust’s metals market exposure is to fluctuations in the price of copper, gold and zinc.

Qualitative Disclosures Regarding Non-Trading Risk Exposure

     The following were the only non-trading risk exposures of the Trust as of June 30, 2006.

Foreign Currency Balances

     The Trust’s primary foreign currency balances are in Japanese Yen, British Pounds and Euros. The Trust controls the non-trading risk of these balances by regularly converting these balances back into dollars (no less frequently than twice a month, and more frequently if a particular foreign currency balance becomes unusually large).

Treasury Bill Positions

     The Trust’s only market exposure in instruments held other than for trading is in its Treasury Bill portfolio. The Trust holds Treasury Bills (interest bearing and credit risk-free) with durations no longer than six months. Violent fluctuations in prevailing interest rates could cause immaterial mark-to-market losses on the Trust’s Treasury Bills, although substantially all of these short-term investments are held to maturity.

Qualitative Disclosures Regarding Means of Managing Risk Exposure

     The means by which Campbell & Company attempts to manage the risk of the Trust’s open positions is essentially the same in all market categories traded. Campbell & Company applies risk management policies to its trading which generally limit the total exposure that may be taken per “risk unit” of assets under management. In addition, Campbell & Company follows diversification guidelines (often formulated in terms of the balanced volatility between markets and correlated groups), as well as imposing “stop-loss” points at which open positions must be closed out.

     Campbell & Company controls the risk of the Trust’s non-trading instruments (Treasury Bills held for cash management purposes) by limiting the duration of such instruments to no more than six months.

General

The Trust is unaware of any (i) anticipated known demands, commitments or capital expenditures; (ii) material trends, favorable or unfavorable, in its capital resources; or (iii) trends or uncertainties that will have a material effect on operations. From time to time, certain regulatory agencies have proposed increased margin requirements on futures contracts. Because the Trust generally will use a small percentage of assets as margin, the Trust does not believe that any increase in margin requirements, as proposed, will have a material effect on the Trust’s operations.

Item 4.Controls and Procedures

Campbell & Company, Inc., the managing owner of the Trust, with the participation of the managing owner’s chief executive officer and chief financial officer, has evaluated the effectiveness of the design and operation of its disclosure controls and procedures (as defined in the Securities Exchange Act of 1934 Rules 13a-15(e) or 15d-15(e)) with respect to the Trust as of the end of the period covered by this quarterly report. Based on their evaluation, the chief executive officer and chief financial officer have concluded that these disclosure controls and procedures are effective. There were no changes in the managing owner’s internal control over financial reporting applicable to the Trust identified in connection with the evaluation required by paragraph (d) of Exchange Act Rules 13a-15 or 15d-15 that occurred during the last fiscal quarter that have materially affected, or is reasonably likely to materially affect, internal control over financial reporting applicable to the Trust.
