The Partnership may trade commodity futures and options contracts of any kind. In addition, the Partnership may enter into swap contracts on energy-related products. The commodity interests that are traded by the Partnership are volatile and involve a high degree of market risk.

Between March 31, 1999 (commencement of the offering period) and June 10, 1999, 10,499 redeemable units of Limited Partnership Interest (‘‘Redeemable Units’’) and 106 Unit equivalents representing the general partner’s contribution were sold at $1,000 per Redeemable Unit. The proceeds of the offering were held in an escrow account until June 10, 1999, at which time they were turned over to the Partnership for trading. The Partnership continues to offer Redeemable Units.

Citigroup Managed Futures LLC a Delaware Limited Liability Company, is the Partnership’s general partner and commodity pool operator (‘‘the General Partner’’). The Partnership’s commodity broker is Citigroup Global Markets Inc. (‘‘CGM’’). CGM is an affiliate of the General Partner. The General Partner is wholly owned by Citigroup Global Markets Holdings Inc. (‘‘CGMHI’’), which is the sole owner of CGM. CGMHI is a wholly-owned subsidiary of Citigroup Inc. (‘‘Citigroup’’). As of March 31, 2007, all trading decisions are made by Willowbridge Associates Inc., (‘‘Willowbridge’’), Winton Capital Management Limited (‘‘Winton’’) and AAA Capital Management Advisors, Ltd. (successor to AAA Capital Management, Inc.) (‘‘AAA’’), (each an ‘‘Advisor’’ and, collectively, the ‘‘Advisors’’). Willowbridge Associates Inc. trades both the Willowbridge Argo and Willowbridge Vulcan trading programs for the Partnership.

5.    Financial Instrument Risks:

In the normal course of its business, the Partnership and the Funds are party to financial instruments with off-balance sheet risk, including derivative financial instruments and derivative commodity instruments. These financial instruments may include forwards, futures, options and swaps, whose values are based upon an underlying asset, index, or reference rate, and generally represent future commitments to exchange currencies or cash flows, or 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. 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 or Funds 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.

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 risk of loss in the event of counterparty default is typically limited to the amounts recognized as unrealized appreciation in the statements of financial condition and not represented by the contract or notional amounts of the instruments. The Partnership and Funds have concentration risk because the sole counterparty or broker with respect to the Partnership’s and Funds’ assets is CGM.

Salomon Smith Barney Orion Futures Fund L.P. Notes to Financial Statements March 31, 2007 (Unaudited)

The General Partner monitors and controls the Partnership’s and Funds’ 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/Funds are 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, forwards and options 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 and Fund’s businesses, these instruments may not be held to maturity.

Item 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. The Partnership’s only assets are its (i) investment in Partnership (ii) equity in its commodity futures trading account consisting of cash, net unrealized appreciation on open futures and forward contracts, commodity options, if applicable, and (iii) interest receivable. Because of the low margin deposits normally required in commodity futures trading, relatively small price movements may result in substantial losses to the Partnership. While substantial losses could lead to a decrease in liquidity, no such losses occurred in the first quarter of 2007.

The Partnership’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 Redeemable Units and distributions of profits, if any.

For the three months ended March 31, 2007, Partnership capital increased 2.5% from $308,398,078 to $315,987,517. This increase was attributable to additional sales of 21,948.5373 Redeemable Units of Limited Partnership totaling $39,596,000, which was partially offset by a net loss from operations of $19,759,914 coupled with the redemption of 6,411.9515 Redeemable Units resulting in an outflow of $11,496,514 and 436.3952 General Partner Unit equivalents totaling $750,133. Future redemptions can impact the amount of funds available for investment in the Partnership 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, and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates.

All commodity interests (including derivative financial instruments and derivative commodity instruments) held by Partnership/Funds’ are used for trading purposes. The commodity interests are recorded on trade date and open contracts are recorded in the statement 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, including dealer quotes for swaps and certain option contracts. The value of the Partnership’s investments in other Partnerships reflects the Partnership’s proportional interest in other Partnerships. 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 values on commodity interests and foreign currencies are recognized in the period in which the contract is closed or the changes occur and are included in net gains (losses) on trading of commodity interests.

Foreign currency contracts are those contracts where the Partnership 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 net equity therein, representing unrealized 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 dates, is included in the statement 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 

14

----

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 on the financial statements.

Results of Operations

During the Partnership’s first quarter of 2007, the Net Asset Value per Redeemable Unit decreased 6.0% from $1,827.79 to $1,718.93 as compared to an increase of 6.1% in the first quarter of 2006. The Partnership experienced a net trading loss (comprised of realized gains (losses) on closed positions and changes in unrealized gains (losses) on open positions and investments in Partnerships) before brokerage commissions and related fees in the first quarter of 2007 of $16,498,257. Losses were primarily attributable to the Partnership’s trading of currencies, grains, metals, indices, softs, U.S. and non-U.S. interest rates and were partially offset by gains in energy. The Partnership experienced a net trading gain before brokerage commissions and related fees in the first quarter of 2006 of $17,257,573. Gains were primarily attributable to the Partnership’s trading of energy, metals, indices and U.S. interest rates and were partially offset by losses in currencies, grains, livestock, non-U.S. interest rates and softs.

The slowing of the U.S. economy continued to weight on the markets as equity prices showed little change amid a significant increase in volatility. In late February, the unanticipated decline of the Shanghai Composite Index triggered a global equity correction as volatility in the financial markets spiked and U.S. recession concerns emerged. The fund was negatively impacted by a number of price trend reversals in both financial and commodity markets as correlation between traditionally unrelated markets linked. Losses were realized in trading fixed income, currency, grains and equity indices

The first quarter of 2007 presented a difficult investment landscape for the Advisors. Fixed income markets exhibited significant volatility whilst remaining largely directionless, resulting in losses for the sector. 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 Euro, Japanese Yen and British Pounds. In grains, prices in the soybean complex unexpectedly jumped as agricultural data indicated a decline in soybean production this year, rendering losses for the sector. A spike in global equity volatility proved a difficult environment for trading as losses were accumulated in equity indices.

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 depends on the existence of major price trends and the ability of the Advisors 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 Advisors are able to identify them, the Partnership expects to increase capital through operations. AAA is aware of price trends but does not trade upon trends. AAA often takes profits in positions with specific trends even though that trend may still be intact or perhaps even stronger. AAA occasionally establishes positions that are counter-trend.

Interest income is earned on 100% of the Partnership’s average daily equity maintained in cash in its account during each month 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 from the date on which such weekly rate is determined. CGM may continue to maintain the Partnership’s assets in cash and/or place all of the Partnership’s assets in 90-day Treasury bills and pay the Partnership 100% of the interest earned on Treasury bills purchased. Interest income for the three months ended March 31, 2007 increased by $135,496 as compared to the corresponding period in 2006. The increase is due to the higher average net assets held for direct trading for the partnership when compared to the corresponding period in 2006. The interest earned at the investment in Partnerships level is included in the Partnership’s share of overall net income (loss) of the other partnerships in 2007 as compared to 2006.

Brokerage commissions are based on the number of trades executed by the Advisors. Brokerage commissions and fees for the three months ended March 31, 2007 increased by $193,249, as compared to 

15

----

the corresponding period in 2006. The increase in commissions and fees is primarily due to an increase in the number of trades 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 increased by $523,287, as compared to the corresponding period in 2006. The increase of management fees is due to an increase in net assets during the three months ended March 31, 2007 as compared to the corresponding period in 2006.

Administrative fees are paid to the General Partner for administering the business and affairs of the Partnership. These 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 and redemptions. Administrative fees for the three months ended March 31, 2007 increased by $146,070, as compared to the corresponding period in 2006. The increase in administrative fees is due to an increase in net assets during the three months ended March 31, 2007 as compared to the corresponding period in 2006.

Incentive fees paid by the Partnership are based on the new trading profits generated by each Advisor at the end of the quarter, as defined in the management agreements between the Partnership, the General Partner and each Advisor. Trading performance for the three months ended March 31, 2007 and 2006 resulted in incentive fees of $0 and $3,102,589, respectively.

Item 3.    Quantitative and Qualitative Disclosures about Market Risk

The Partnership is a speculative commodity pool. The market sensitive instruments held by Partnership/Funds are acquired for speculative trading purposes, and all or substantially all of the Partnership’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 Partnership’s main line of business.

Market movements result in frequent changes in the fair value of the Partnership’s open positions and, consequently, in its earnings and cash flow. The Partnership’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 Partnership’s open positions and the liquidity of the markets in which it trades.

The Partnership 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 Partnership’s past performance is not necessarily indicative of its future results.

Value at Risk is a measure of the maximum amount which the Partnership could reasonably be expected to lose in a given market sector. However, the inherent uncertainty of the Partnership’s speculative trading and the recurrence in the markets traded by the Partnership of market movements far exceeding expectations could result in actual trading or non-trading losses far beyond the indicated Value at Risk or the Partnership’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 Partnership’s losses in any market sector will be limited to Value at Risk or by the Partnership’s attempts to manage its market risk.

Exchange maintenance margin requirements have been used by the Partnership 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 Partnership’s investments and investments in other Partnerships by market category as of March 31, 2007 and the highest, lowest and average value during the three months ended March 31, 2007. All open position trading risk exposures of the Partnership have been included in calculating the figures set forth below. As of March 31, 2007, the Partnership’s total capitalization was $315,987,517. There has been no material change in the trading Value at Risk information previously disclosed in the Partnership’s Annual Report on Form 10-K for the year ended December 31, 2006.
