Smith Barney Westport Futures Fund L.P.Notes to Financial StatementsJune 30, 2007 (Unaudited)

1.    General:

Smith Barney Westport Futures Fund L.P. (the ‘‘Partnership’’) is a limited partnership which was organized on March 21, 1997 under the partnership laws of the State of New York to engage in the speculative trading of a diversified portfolio of commodity interests including futures contracts, options and forward contracts. The commodity interests that are traded by the Partnership are volatile and involve a high degree of market risk.

Citigroup Managed Futures LLC, a Delaware limited liability company, acts as the general partner (the ‘‘General Partner’’) of the Partnership. The Partnership’s commodity broker is Citigroup Global Markets (‘‘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. As of June 30, 2007, all trading decisions for the Partnership are made by John W. Henry & Company, Inc. (the ‘‘Advisor’’).

The accompanying financial statements are unaudited but, in the opinion of management, include all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation of the Partnership’s financial condition at June 30, 2007 and December 31, 2006, and the results of its operations and cash flows for the three and six months ended June 30, 2007 and 2006. These financial statements present the results of interim periods and do not include all disclosures normally provided in annual financial statements. You should read these financial statements together with the financial statements and notes included in the Partnership’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (the ‘‘SEC’’) for the year ended December 31, 2006.

Due to the nature of commodity trading, the results of operations for the interim periods presented should not be considered indicative of the results that may be expected for the entire year.

The above ratios may vary for individual investors based on the timing of capital transactions during the period. Additionally, these ratios are calculated for the Limited Partner class using the Limited Partners’ share of income, expenses and average net assets.

3.    Trading Activities:

The Partnership was formed for the purpose of trading contracts in a variety of commodity interests, including derivative financial instruments and derivative commodity instruments. The results of the Partnership’s trading activities are shown in the Statements of Income and Expenses and Partners’ Capital and are discussed in Item 2, Management’s Discussion and Analysis of Financial Condition and Results of Operations.

The Customer Agreement between the Partnership and CGM gives the Partnership the legal right to net unrealized gains and losses on open futures positions.

All of the commodity interests owned by the Partnership are held for trading purposes. The average fair values of these interests during the six and twelve months ended June 30, 2007 and December 31, 2006, based on a monthly calculation, were $760,967 and $3,139,285, respectively. The fair values of these commodity interests, including options thereon, if applicable, at June 30, 2007 and December 31, 2006, were $1,402,407 and $681,558, respectively. Fair values for exchange traded commodity futures and options are based on quoted market prices for those futures and options. Fair values for all other financial instruments for which market quotations are not readily available are based on other measures of fair value deemed appropriate by the General Partner.

4.    Financial Instrument Risks:

In the normal course of its business, the Partnership 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. 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 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 has credit risk and concentration risk because the sole counterparty or broker with respect to the Partnership’s assets is CGM.

The General Partner monitors and controls the Partnership’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 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 June 30, 2007. However, due to the nature of the Partnership’s business, 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. Its only assets are its equity in its commodity futures trading account, consisting of cash, net unrealized appreciation on open futures, unrealized appreciation on forward contracts and 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 substantial decrease in liquidity, no such losses occurred in the second quarter of 2007.

The Partnership’s capital consists of capital contributions, as increased or decreased by realized and/or unrealized gains or losses on commodity futures trading and expenses, interest income, redemptions of Redeemable Units and distributions of profits, if any.

For the six months ended June 30, 2007, Partnership capital decreased 30.0% from $99,986,338 to $70,021,413. This decrease was attributable to a net loss from operations of $7,774,885, coupled with the redemption of 24,671.2067 Redeemable Units of Limited Partnership Interest totaling $23,700,361, and General Partners equivalent Units of 477.0956 totaling $430,679, which was partially offset by additional sales of 1,958.6602 Redeemable Units of Limited Partnership Interest totaling $1,941,000. Future redemptions can impact the amount of funds available for investment 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 (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 values on open positions 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 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.

In July 2006, the Financial Accounting Standards Board (‘‘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 adopted FIN 48 as of January 1, 2007 and the application of this standard did not impact the financial statements.

In September 2006, the FASB issued Statement of Financial Accounting Standards (‘‘SFAS’’) No. 157, Fair Value Measurements. This accounting standard establishes a single authoritative definition of fair values, sets out a framework for measuring fair value and expands disclosures about fair value measurements. SFAS No. 157 applies to fair value measurements already required or permitted by existing standards. SFAS No. 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007, and the interim periods within those fiscal years. As of June 30, 2007, the Partnership is still evaluating the impact the adoption of SFAS No. 157 will have on the financial statement amounts; however, additional disclosures will be required about the inputs used to develop the measurements and the effect of certain measurements on changes in Partners’ Capital for the period.

Results of Operations

During the Partnership’s second quarter of 2007, the Net Asset Value Per Redeemable Unit increased 5.7% from $902.71 to $954.35, as compared to a decrease of 2.3% in the second quarter of 2006. The Partnership experienced a net trading gain (comprised of realized gains (losses) on closed positions and change in unrealized gains (losses) on open positions) before brokerage commissions and related fees in the second quarter of 2007 of $5,012,623. Gains were primarily attributable to the trading of commodity futures in currencies, energy, U.S. and non- U.S. interest rates, and indices and were partially offset by losses in grains, metals, livestock and softs. The Partnership experienced a net trading loss before brokerage commissions and related fees in the second quarter of 2006 of $962,513. Losses were primarily attributable to the trading of commodity futures in currencies, softs, grains and indices and were partially offset by gains in metals, energy, U.S. and non-U.S. interest rates.

The second quarter presented a favorable trading environment to the trading advisor, as trends emerged in several sectors, most notably in fixed income and currencies. Inflationary pressures remained high in several economies as they continued to show strong growth characteristics and resilience even as the central banks increased the interest rates or kept them high relative to recent past. The Partnership registered minor losses in trading agricultural products and metals and posted gains in currencies, fixed income, stock indices and energy.

In the currency market. strong trends emerged as the Japanese Yen weakened relative to the U.S. Dollar. The Partnership was favorably positioned to register gains by capturing this trend through the quarter. Trading was also profitable in the Australian Dollar and the Brazilian Real. In the fixed income sector, gains were realized as the economic data suggested continued growth and elevated inflationary pressures in several major world economies. As the global stock indices continued to reach new record levels. the Partnership was favorably positioned to profit from the long-term trends in this sector. Energy sector also presented favorable conditions as moderate gains were registered, especially trading natural gas.

Minor losses were realized in agricultural products, especially in corn, wheat and sugar. In the metals sector, losses were registered in precious metals while there were modest gains from copper.

During the Partnership’s six months ended June 30, 2007, the Net Asset Value Per Redeemable Unit decreased 7.8% from $1,035.48 to $954.35, as compared to a decrease of 10.1% for the six months ended June 30, 2006. The Partnership experienced a net trading loss (comprised of realized gains (losses) on closed positions and change in unrealized gains (losses) on open positions) before brokerage commissions and related fees for the six months ended June 30, 2007, of $6,142,197. Losses were primarily attributable to the trading of commodity futures in currencies, energy, grains, U.S. interest rates, livestock, metals, softs and indices and were partially offset by gains in non-U.S. interest rates. The Partnership experienced a net trading loss before brokerage commissions and related fees for the six months ended June 30, 2006 of $11,144,777. Losses were primarily attributable to the trading of commodity futures in currencies, energy, grains, livestock and softs and were partially offset by gains in metals, indices, U.S. and non-U.S. Interest rates.

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 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 expects to increase capital through operations.

Interest income on 80% of the Partnership’s daily average equity maintained in cash 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 Partnership’s assets in cash and/or place all of the Partnership’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 interest earned on Treasury bills. Interest income for the three and six months ended June 30, 2007 decreased by $550,186 and $771,458, respectively, as compared to the corresponding periods in 2006. The decrease is due to lower average net assets during the three and six months ended June 30, 2007 as compared to the corresponding periods 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 and six months ended June 30, 2007 decreased by $881,823 and $1,533,485, respectively, as compared to the corresponding periods in 2006. The decrease in brokerage commissions and fees is due to lower average adjusted net assets during the three and six months ended June 30, 2007 as compared to the corresponding periods in 2006.

Management fees are calculated as a percentage of the Partnership’s adjusted net asset value as of the end of each month and are affected by trading performance, additions and redemptions. Management fees for the three and six months ended June 30, 2007 decreased by $307,515 and $530,625, as compared to the corresponding periods in 2006. The decrease in management fees is due to lower average adjusted net assets during the three and six months ended June 30, 2007 as compared to the corresponding periods 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 for the three and six months ended June 30, 2007 and 2006.

Item 3.    Quantitative and Qualitative Disclosures about Market Risk

The Partnership 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 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 market 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 open positions by market category as of June 30, 2007 and the highest, lowest and average values during the three months ended June 30, 2007. All open position trading risk exposures of the Partnership have been included in calculating the figures set forth below. As of June 30, 2007, the Partnership’s total capitalization was $70,021,413. 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.

Item 4.    Controls and Procedures

The Partnership’s disclosure controls and procedures are designed to ensure that information required to be disclosed under the Exchange Act is accumulated and communicated to management, including the Chief Executive Officer (CEO) and Chief Financial Officer (CFO) of the General Partner, to allow for timely decisions regarding required disclosure and appropriate SEC filings.

Management is responsible for ensuring that there is an adequate and effective process for establishing, maintaining and evaluating disclosure controls and procedures for the Partnership’s external disclosures.

The General Partner’s CEO and CFO have evaluated the effectiveness of the Partnership’s disclosure controls and procedures (as defined in Rule 13a-15(e) and 15d-15(e) under the Exchange Act) as of June 30, 2007 and, based on that evaluation, the CEO and CFO have concluded that at that date the Partnership’s disclosure controls and procedures were effective.

The Partnership’s internal control over financial reporting is a process under the supervision of the General Partner’s CEO and CFO to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements in accordance with generally accepted accounting principles. These controls include policies and procedures that:
