In the normal course of its business, the Partnership, through its investment in the Master, is party to financial instruments with off-balance sheet risk, including derivative financial instruments and derivative commodity instruments. These financial instruments may include forwards, futures and options, whose values are based upon an underlying asset, index, or reference rate, and generally represent future commitments to exchange currencies or cash flows, to purchase or sell other financial instruments at specific terms at specified future dates, or, in the case of derivative commodity instruments, to have a reasonable possibility to be settled in cash, through physical delivery or with another financial instrument. The Fund may trade commodity options. Specific market movements of the commodities or futures contracts underlying an option cannot accurately be predicted. The purchaser of an option may lose the entire premium paid for the option. The writer, o r seller, of an option has unlimited risk. These instruments may be traded on an exchange or over-the-counter (‘‘OTC’’). Exchange-traded instruments are standardized and include futures and certain option contracts. OTC contracts are negotiated between contracting parties and include forwards and certain options.
Each of these instruments is subject to various risks similar to those related to the underlying financial instruments including market and credit risk. In general, the risks associated with OTC contracts are greater than those associated with exchange-traded instruments because of the greater risk of default by the counterparty to an OTC contract.
Market risk is the potential for changes in the value of the financial instruments traded by the Partnership/Master due to market changes, including interest and foreign exchange rate movements and fluctuations in commodity or security prices. Market risk is directly impacted by the volatility and liquidity in the markets in which the related underlying assets are traded by the Master.
Credit risk is the possibility that a loss may occur due to the failure of a counterparty to perform according to the terms of a contract. Credit risk with respect to exchange-traded instruments is reduced to the extent that an exchange or clearing organization acts as a counterparty to the transactions. The Partnership’s/Master’s risk of loss in the event of counterparty default is typically limited to the amounts recognized in the statements of financial condition and not represented by the contract or notional amounts of the instruments. The Partnership, through its investment in the Master, has credit risk and concentration risk because the sole counterparty or broker with respect to the Master’s assets is CGM.
The General Partner monitors and controls the Partnership’s/Master’s risk exposure on a daily basis through financial, credit and risk management monitoring systems, and accordingly believes that it has effective procedures for evaluating and limiting the credit and market risks to which the Partnership/Master is subject. These monitoring systems allow the General Partner to statistically analyze actual trading results with risk adjusted performance indicators and correlation statistics. In addition, on-line monitoring systems provide account analysis of futures, forward and option positions by sector, margin requirements, gain and loss transactions and collateral positions.
The majority of these instruments mature within one year of March 31, 2007. However, due to the nature of the Partnership’s/Master’s business, these instruments may not be held to maturity.
Table of ContentsItem 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.
Liquidity and Capital Resources
The Partnership does not engage in the sale of goods or services. Its only assets are its investment in the Master and cash. The Master does not engage in the sale of goods or services. Because of the low margin deposits normally required in commodity futures trading, relatively small price movements may result in substantial losses to the Partnership/Master. While substantial losses could lead to a substantial decrease in liquidity, no such losses occurred in the first quarter of 2007.
The Partnership’s capital consists of capital contributions, as increased or decreased by its investment in the Master, expenses, interest income, redemptions of Redeemable Units and distributions of profits, if any.
For the three months ended March 31, 2007, Partnership capital decreased 9.6% from $229,858,247 to $207,782,182. This decrease was attributable to a net loss from operations of $15,867,105 coupled with the redemption of 4,448.6153 Redeemable Units of Limited Partnership Interest totaling $7,978,960, which was partially offset by additional sales of 961.4288 Redeemable Units of Limited Partnership Interest totaling $1,770,000. Future redemptions can impact the amount of funds available for investment in commodity contract positions in subsequent periods.
The Master’s capital consists of the capital contributions of the partners as increased or decreased by realized and/or unrealized gains or losses on commodity futures trading, expenses, interest income, redemptions of Units and distributions of profits, if any.
For the three months ended March 31, 2007, the Master’s capital decreased 11.7% from $327,090,390 to $288,929,775. This decrease was attributable to a net loss from operations of $15,198,428 coupled with the redemption of 17,873.2954 units totaling $21,751,778, which was partially offset by additional sales of 1,450.4636 Units totaling $1,770,000 and distribution of interest totaling $2,980,409 to the limited partners of the Master. Future redemptions can impact the amount of funds available for investments in commodity contract positions in subsequent periods.
Critical Accounting Policies
The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities at the date of the financial statements and reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates.
All commodity interests of the Master (including derivative financial instruments and derivative commodity instruments) are used for trading purposes. The commodity interests are recorded on trade date and open contracts are recorded in the Statements of Financial Condition at fair value on the last business day of the period, which represents market value for those commodity interests for which market quotations are readily available or other measures of fair value deemed appropriate by management of the General Partner for those commodity interests and foreign currencies for which market quotations are not readily available. Investments in commodity interests denominated in foreign currencies are translated into U.S. dollars at the exchange rates prevailing on the last business day of the period. Realized gains (losses) and changes in unrealized gains (losses) on open positions are recognized in the period in which the contract is closed or the changes occur a nd are included in net gains (losses) on trading of commodity interests.
The value of the Partnership’s investment in the Master reflects the Partnership’s proportional interest in the Partners’ capital of the Master. All of the income and expenses and unrealized and realized gains and losses from the commodity transactions of the Master are allocated pro rata among the investors at the time of such determination.
Foreign currency contracts are those contracts where the Partnership/Master agrees to receive or deliver a fixed quantity of foreign currency for an agreed-upon price on an agreed future date. Foreign currency contracts are valued daily, and the Partnership’s/Master’s net equity therein, representing
15
Table of Contentsunrealized gain or loss on the contracts as measured by the difference between the forward foreign exchange rates at the dates of entry into the contracts and the forward rates at the reporting date, is included in the Statements of Financial Condition. Realized gains (losses) and changes in unrealized values on foreign currency contracts are recognized in the period in which the contract is closed or the changes occur and are included in the Statements of Income and Expenses and Partners’ Capital.
On July 13, 2006, the FASB released FASB Interpretation No. 48 ‘‘Accounting for Uncertainty in Income Taxes’’ (FIN 48). FIN 48 provides guidance for how uncertain tax positions should be recognized, measured, presented and disclosed in the financial statements. FIN 48 requires the evaluation of tax positions taken or expected to be taken in the course of preparing the Partnership’s tax returns to determine whether the tax positions are ‘‘more-likely-than-not’’ of being sustained by the applicable tax authority. Tax positions not deemed to meet the more-likely-than-not threshold would be recorded as a tax benefit or expense in the current year. The Partnership has adopted FIN 48 and management has determined that the application of this standard will not impact the financial statements.
Results of Operations
During the Partnership’s first quarter of 2007 the net asset value per Redeemable unit decreased 7.0% from $1,844.57 to $1,715.42 compared to an increase of 4.2% in the first quarter of 2006. The Partnership experienced a net trading loss (comprised of realized losses on closed positions allocated from Master and change in unrealized gains (losses) on open positions allocated from Master) before brokerage commissions and related fees in the first quarter of 2007 of $13,168,855. Losses were primarily attributable to the Master’s trading of commodity futures in currencies, U.S. and non-U.S. interest rates, metals and energy and were partially offset by gains in indices. The Partnership experienced a net trading gain before brokerage commissions and related fees in the first quarter of 2006 of $14,826,859. Gains were primarily attributable to the Master’s trading of commodity futures in currencies, U.S. interest rates, livestock, metal and indices and were partially offset by losses in non-U.S. interest rates.
The first quarter of 2007 presented a challenging trading environment to the trading Advisor due to several short-term price reversals triggered by a precipitous decline in the world equity markets towards the end of February. The price reversals caused a sharp increase in the short-term correlation among several sectors thereby eliminating the diversification benefits. The fund registered losses in currencies, energy, fixed income and metals while gains were made in stock indices.
Currency markets were dominated by short-term reversals for the quarter as mixed global and regional economic data caused the markets to move erratically. Speculation over further widening of global interest rate differentials continued to negatively impact certain currency positions, such as Japanese Yen and British Pounds. Fixed income markets exhibited significant volatility whilst remaining largely directionless, resulting in losses for the sector. Price trends in base metals were not favorable, causing losses in Copper and Zinc through the quarter.
The fund registered gains in the stock indices early in the quarter driven by continuing trend from previous year. Some of the gains were given back as short-term price reversal and increased volatility were seen in the world equity markets towards the end of February.
Commodity futures markets are highly volatile. The potential for broad and rapid price fluctuations increases the risks involved in commodity trading, but also increases the possibility of profit. The profitability of the Partnership (and the Master) depends on the existence of major price trends and the ability of the Advisor to correctly identify those price trends. Price trends are influenced by, among other things, changing supply and demand relationships, weather, governmental, agricultural, commercial and trade programs and policies, national and international political and economic events and changes in interest rates. To the extent that market trends exist and the Advisor is able to identify them, the Partnership (and the Master) expects to increase capital through operations.
Interest income on 80% of the Partnership’s daily average equity allocated to it by the Master was earned at a 30-day U.S. Treasury bill rate determined weekly by CGM based on the average non-competitive yield on 3-month U.S. Treasury bills maturing in 30 days. CGM may continue to maintain the Master’s assets in cash and/or place all of the Master’s assets in 90-day Treasury bills and pay the Partnership 80% of the interest earned on the Treasury bills purchased. CGM will retain 20% of any
16
Table of Contentsinterest earned on Treasury bills. Interest income allocated from the Master for the three months ended March 31, 2007 increased by $94,509 as compared to the corresponding period in 2006. The increase in interest income is primarily due to higher interest rates during the three months ended March 31, 2007 as compared to the corresponding period in 2006.
Brokerage commissions are calculated on the Partnership’s adjusted net asset value on the last day of each month and are affected by trading performance, additions and redemptions. Accordingly, they must be analyzed in relation to the fluctuations in the monthly net asset values. Commissions and fees for the three months ended March 31, 2007 decreased by $414,922 as compared to the corresponding period in 2006. The decrease in brokerage commissions and fees is due to lower net assets during the three months ended March 31, 2007 as compared to the corresponding period in 2006.
Management fees are calculated as a percentage of the Partnership’s net asset value as of the end of each month and are affected by trading performance, additions and redemptions. Management fees for the three months ended March 31, 2007 decreased by $126,039 as compared to the corresponding period in 2006. The decrease in management fees is due to lower net assets during the three months ended March 31, 2007 as compared to the corresponding period in 2006.
Incentive fees are based on the new trading profits generated by the Advisor at the end of the quarter as defined in the advisory agreements between the Partnership, the General Partner and the Advisor. There were no incentive fees earned for the three months ended March 31, 2007. Trading performance for the three months ended March 31, 2006 resulted in incentive fees of $1,237,713.

Table of ContentsItem 3. Quantitative and Qualitative Disclosures about Market Risk
All of the Partnership’s assets are subject to the risk of trading loss through its investment in the Master. The Master is a speculative commodity pool. The market sensitive instruments held by it are acquired for speculative trading purposes, and all or substantially all of the Master’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 Master’s main line of business.
Market movements result in frequent changes in the fair market value of the Master’s open positions and, consequently, in its earnings and cash flow. The Master’s market risk is influenced by a wide variety of factors, including the level and volatility of interest rates, exchange rates, equity price levels, the market value of financial instruments and contracts, the diversification effects among the Master’s open positions and the liquidity of the markets in which it trades.
The Master 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 Master’s past performance is not necessarily indicative of its future results.
Value at Risk is a measure of the maximum amount which the Master could reasonably be expected to lose in a given market sector. However, the inherent uncertainty of the Master’s speculative trading and the recurrence in the markets traded by the Master of market movements far exceeding expectations could result in actual trading or non-trading losses far beyond the indicated Value at Risk or the Master’s experience to date (i.e., ‘‘risk of ruin’’). In light of the foregoing as well as the risks and uncertainties intrinsic to all future projections, the inclusion of the quantification in this section should not be considered to constitute any assurance or representation that the Master’s losses in any market sector will be limited to Value at Risk or by the Master’s attempts to manage its market risk.
Exchange maintenance margin requirements have been used by the Master as the measure of its Value at Risk. Maintenance margin requirements are set by exchanges to equal or exceed the maximum losses reasonably expected to be incurred in the fair value of any given contract in 95%-99% of any one-day interval. Maintenance margin has been used rather than the more generally available initial margin, because initial margin includes a credit risk component, which is not relevant to Value at Risk.
The following table indicates the trading Value at Risk associated with the Master’s open positions by market category as of March 31, 2007 and the highest, lowest and average values during the three months ended March 31, 2007. All open position trading risk exposures of the Master have been included in calculating the figures set forth below. As of March 31, 2007, the Master’s total capitalization was $288,929,775.
