	1.    General:
	Westport Futures Fund L.P. (formerly, Westport JWH Futures Fund L.P.) (the “Partnership”) is a limited partnership organized on March 21, 1997 under the partnership laws of the State of New York to engage, directly and indirectly, in the speculative trading of a diversified portfolio of commodity interests, including futures, options on futures, forwards, options on forwards, spot and swap contracts, cash commodities and any other rights or interests pertaining thereto including interest in commodity pools. The Partnership may also engage in exchange for physical transactions. The sectors traded include U.S. and international markets for energy, currencies, interest rates, indices, agricultural products and metals. The Partnership commenced trading on August 1, 1997. The commodity interests that are traded by the Partnership, through its investment in Rabar Master Fund L.P. (the “Master”), are volatile and involve a high degree of market risk. The Partnership privately and continuously offers redeemable units (“Redeemable Units”) to qualified investors. There is no maximum number of Redeemable Units that may be sold by the Partnership.
	Ceres Managed Futures LLC, a Delaware limited liability company, acts as the general partner (the “General Partner”) and commodity pool operator of the Partnership. The General Partner is wholly owned by Morgan Stanley Smith Barney Holdings LLC (“MSSB Holdings”). MSSB Holdings is ultimately owned by Morgan Stanley. Morgan Stanley is a publicly held company whose shares are listed on the New York Stock Exchange. Morgan Stanley is engaged in various financial services and other businesses. Prior to June 28, 2013, Morgan Stanley indirectly owned a majority equity interest in MSSB Holdings and Citigroup Inc. indirectly owned a minority equity interest in MSSB Holdings. Prior to July 31, 2009, the date as of which MSSB Holdings became its owner, the General Partner was wholly owned by Citigroup Financial Products Inc., a wholly owned subsidiary of Citigroup Global Markets Holdings Inc., the sole owner of which is Citigroup Inc.
	As of March 31, 2014, all trading decisions for the Partnership are made by Rabar Market Research Inc. (“Rabar”).
	During the three months ended March 31, 2014, the Partnership’s/Master’s commodity broker was Morgan Stanley & Co. LLC (“MS&Co.”). During prior periods included in this report, Citigroup Global Markets Inc. (“CGM”) also served as a commodity broker.
	During the second quarter of 2013, the Master entered into a futures brokerage account agreement and a foreign exchange brokerage account agreement with MS&Co, a registered futures commission merchant. The Master commenced foreign exchange trading through an account at MS&Co on or about April 12, 2013, and futures trading through an account at MS&Co on or about June 24, 2013. Effective August 2, 2013, the Partnership entered into a futures brokerage account agreement with MS&Co. and began transferring the brokerage account of the Partnership from CGM to MS&Co. The Partnership, through its investment in the Master, will pay MS&Co. trading fees for the clearing and, where applicable, execution of transactions.
	Effective October 1, 2013, the Partnership ceased paying a brokerage fee to CGM and CGM ceased acting as a selling agent for the Partnership. Also effective October 1, 2013, the Partnership entered into a selling agreement with Morgan Stanley Smith Barney LLC (d/b/a Morgan Stanley Wealth Management). Pursuant to the selling agreement, Morgan Stanley Wealth Management received a selling agent fee equal to 5.25% per year of month-end net assets. The selling agent fee received by Morgan Stanley Wealth Management will be shared with the properly registered/licensed financial advisers of Morgan Stanley Wealth Management who sold redeemable units in the Partnership.
	Effective April 1, 2014, the monthly ongoing selling agent fee was reduced from an annual rate of 5.25% to an annual rate of 3.00%.
	Certain prior period amounts have been reclassified to conform to current period presentation. Amounts reported separately on the Statements of Income and Expenses and Changes in Partners’ Capital as ongoing selling agent fees and clearing fees were previously combined and presented as brokerage fees, including clearing fees.
	The General Partner and each limited partner of the Partnership share in the profits and losses of the Partnership in proportion to the amount of Partnership interest owned by each except, that no limited partner is liable for obligations of the Partnership in excess of its capital contribution and profits, if any, net of distributions and losses, if any.
	The accompanying financial statements and accompanying notes are unaudited but, in the opinion of management, include all adjustments, consisting only of normal recurring adjustments, necessary for a fair statement of the Partnership’s financial condition at March 31, 2014 and December 31, 2013, and the results of its operations and changes in partners’ capital for the three months ended March 31, 2014, and 2013. 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, 2013.
	The preparation of financial statements and accompanying notes in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, income and expenses, and related disclosures of contingent assets and liabilities in the financial statements and accompanying notes. As a result, actual results could differ from these estimates.
	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.

Trading Activities	'
	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 Changes in Partners’ Capital.
	The customer agreements between the Partnership, CGM and the Master gave and the customer agreement with the Partnership, MS&Co. and the Master gives the Partnership and the Master, the legal right to net unrealized gains and losses on open futures and open forward contracts. The Partnership and the Master net, for financial reporting purposes, the unrealized gains and losses on open futures and on open forward contracts on the Statements of Financial Condition as the criteria under Accounting Standards Codification (“ASC”) 210-20, “Balance Sheet” have been met.
	The monthly average number of futures contracts traded by the Master during the three months ended March 31, 2014 and 2013 were 2,204 and 1,704, respectively. The monthly average number of metal forward contracts traded by the Master during the three months ended March 31, 2014 and 2013 were 170 and 153, respectively. The monthly average notional values of currency forward contracts held by the Master during the three months ended March 31, 2014 and 2013 were $10,292,148 and $32,074,364, respectively.
	All of the commodity interest owned by the Partnership are held for trading purposes.
	Brokerage fees previously paid to CGM were calculated as a percentage of the Partnership’s adjusted net asset value on the last day of each month and were affected by trading performance, subscriptions and redemptions. Trading and transaction fees are based on the number of trades executed by the Advisor for the Master.
	The Partnership adopted Accounting Standards Update (“ASU”) 2011-11, “Disclosure about Offsetting Assets and Liabilities” and ASU 2013-01, “Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities”. ASU 2011-11 created a new disclosure requirement about the nature of an entity’s rights to setoff and the related arrangements associated with its financial instruments and derivative instruments, while ASU 2013-01 clarified the types of instruments and transactions that are subject to the offsetting disclosure requirements established by ASU 2011-11. Entities are required to disclose both gross information and net information about both instruments and transactions eligible for offset in the statement of financial position and instruments and transactions subject to an agreement similar to a master netting arrangement. The objective of these disclosures is to facilitate comparison between those entities that prepare their financial statements on the basis of U.S. GAAP and those entities that prepare their financial statements on the basis of International Financial Reporting Standards (“IFRS”).

Fair Value Measurements	'
	4.    Fair Value Measurements:
	Partnership’s and the Master’s Investments. All commodity interests held by the Partnership and the Master (including derivative financial instruments and derivative commodity instruments) are held for trading purposes. The commodity interests are recorded on trade date and open contracts are recorded at fair value (as described below) at the measurement date. Investments in commodity interests denominated in foreign currencies are translated into U.S. dollars at the exchange rates prevailing at the measurement date. Gains or losses are realized when contracts are liquidated. Unrealized gains or losses on open contracts are included as a component of equity in trading account on the Statements of Financial Condition. Net realized gains or losses and any change in net unrealized gain or loss from the preceding period are reported in the Statements of Income and Expenses and Changes in Partners’ Capital.
	Partnership’s and the Master’s Fair Value Measurements. Fair Value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date under current market conditions. The fair value hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to fair values derived from unobservable inputs (Level 3). The level in the fair value hierarchy within which the fair value measurement in its entirety falls shall be determined based on the lowest level input that is significant to the fair value measurement in its entirety. Management has concluded that based on available information in the marketplace, the Master’s Level 1 assets and liabilities are actively traded.
	GAAP also requires the use of judgment in determining if a formerly active market has become inactive and in determining fair values when the market has become inactive. Management has concluded that based on available information in the marketplace, there has not been a significant decrease in the volume and level of activity in the Partnership’s Level 2 assets and liabilities.
	The Partnership and the Master will separately present purchases, sales, issuances and settlements in their reconciliation of Level 3 fair value measurements (i.e., to present such items on a gross basis rather than on a net basis), and make disclosures regarding the level of disaggregation as well as the inputs and valuation techniques used to measure fair value for measurements that fall within either Level 2 or Level 3 of the fair value hierarchy as required by GAAP.
	On October 1, 2012, the Financial Accounting Standards Board (the “FASB”) issued ASU 2012-04 “Technical Corrections and Improvements,” which makes minor technical corrections and clarifications to Accounting Standards Codification (“ASC”) 820, “Fair Value Measurements and Disclosures.” When the FASB issued Statement 157 (codified in ASC 820), it conformed the use of the term “fair value” in certain pre-Codification standards but not others. ASU 2012-04 conforms the term’s use throughout the ASC “to fully reflect the fair value measurement and disclosure requirements” of ASC 820. ASU 2012-04 also amends the requirements that must be met for an investment company to qualify for the exemption from presenting a statement of cash flows. Specifically, it eliminates the requirements that substantially all of an entity’s investments be carried at “market value” and that the investments be highly liquid. Instead, it requires substantially all of the entity’s investments to be carried at “fair value” and classified as Level 1 or Level 2 measurements under ASC 820.
	The Partnership and the Master consider prices for exchange-traded commodity futures, forward, swaps and option contracts to be based on unadjusted quoted prices in active markets for identical assets and liabilities (Level 1). The values of non-exchange-traded forwards, swaps and option contracts for which market quotations are not readily available are priced by broker-dealers that derive fair values for those assets and liabilities from observable inputs (Level 2). Investments in the Master (or other commodity pools) with no rights or obligations inherent within the ownership interest held by the Partnership are priced based on the end of the day net asset value of the Master (Level 2). The value of the Partnership’s investment in the Master reflects its proportional interest in the Master. As of and for the periods ended March 31, 2014, and December 31, 2013, the Partnership and the Master did not hold any derivative instruments that were priced at fair value using unobservable inputs through the application of management’s assumptions and internal valuation pricing models (Level 3).
	During the three months ended March 31, 2014 and for the twelve months ended December 31, 2013, there were no transfers of assets or liabilities between Level 1 and Level 2.

	5.    Investment in Master:
	Effective December 1, 2012, the Partnership allocated substantially all of its capital to the Master, a limited liability partnership organized under the partnership laws of the State of Delaware. The Partnership purchased an interest in the Master with cash equal to $31,143,887. The Master permits accounts managed now and in the future by the Advisor using the Diversified Program, a propriety, systematic trading program, to invest together in one trading vehicle. The General Partner is also the general partner of the Master. During the three months ended March 31, 2014, the Master’s commodity broker was MS&Co. During prior periods included in this report, CGM also served as a commodity broker to the Master. Individual and pooled accounts currently managed by the Advisor, including the Partnership, are permitted to be limited partners of the Master. The General Partner and the Advisor believe that trading through this master-feeder structure promotes efficiency and economy in the trading process. Expenses to investors as a result of the investment in the Master are approximately the same and redemption rights are not affected.
	The General Partner is not aware of any material changes to the trading program discussed above during the fiscal quarter ended March 31, 2014.
	The Master’s trading of futures, forward, swaps and option contracts, if applicable, on commodities is done primarily on U.S. commodity exchanges and foreign commodity exchanges. During the reporting period the Master engaged in such trading through commodity brokerage accounts maintained by MS&Co. During the periods included in this report, the Master also engaged in such trading through commodity brokerage accounts maintained by CGM.
	A limited partner of the Master may withdraw all or part of its capital contributions and undistributed profits, if any, from the Master as of the end of any day (the “Redemption Date”) after a request for redemption has been made to the General Partner at least 3 days in advance of the Redemption Date. Such withdrawals are classified as a liability when the limited partner elects to redeem and informs the Master.
	Management and incentive fees are charged at the Partnership level. All clearing fees are borne by the Partnership and through its investment in the Master and allocated to its limited partners including the Partnership. All other fees are charged at the Partnership level.
	As of March 31, 2014, the Partnership owned approximately 79.1% of the Master. As of December 31, 2013, the Partnership owned approximately 77.7% of the Master. The Partnership intends to continue to invest all of its assets in the Master. The performance of the Partnership is directly affected by the performance of the Master.
	The Master’s Statements of Financial Condition and Condensed Schedules of Investments as of March 31, 2014 and December 31, 2013 and Statements of Income and Expenses and Changes in Partners’ Capital for the three months ended March 31, 2014, are presented below:

The Master considers prices for exchange-traded commodity futures and forward contracts to be based on unadjusted quoted prices in active markets for identical assets and liabilities (Level 1). The values of non-exchange-traded forward contracts for which market quotations are not readily available are priced by broker-dealers that derive fair values for those assets and liabilities from observable inputs (Level 2). As of and for the periods ended March 31, 2014, and December 31, 2013, the Master did not hold any derivative instruments that were priced at fair value using unobservable inputs through the application of management’s assumptions and internal valuation pricing models (Level 3).
For the three months ended March 31, 2014 and for the year ended December 31, 2013, there were no transfers of assets or liabilities between Level 1 and Level 2.

Financial Instrument Risks	'
	6.    Financial Instrument Risks:
	In the normal course of 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, 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 balances, to purchase or sell other financial instruments on specific terms on 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 a swap-execution facility or over-the-counter (“OTC”). Exchange-traded instruments include futures and certain standardized forwards, swaps and option contracts. Certain swap contracts may also be traded on a swap execution facility of OTC. OTC contracts are negotiated between contracting parties and also include certain forward and option contracts. Specific market movements of commodities or futures contracts underlying an option cannot be accurately predicted. The purchaser of an option may lose the entire premium paid for the option. The writer or seller of an option has unlimited risk. Each of these instruments is subject to various risks similar to those relating 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. The General Partner estimates at any given time approximately 1.2% to 6.6% of the Partnership’s/Master’s contracts are traded OTC.
	The risk to the limited partners that have purchased Redeemable Units is limited to their share of the Partnership’s net assets and undistributed profits. This limited liability is a result of the organization of the Partnership as a limited partnership under New York law.
	Market risk is the potential for changes in the value of the financial instruments traded by the Partnership and the 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. The Partnership and the Master are exposed to market risk equal to the value of futures and forward contracts purchased and unlimited liability on such contracts sold short.
	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. The Partnership’s and the Master’s risk of loss in the event of a counterparty default is typically limited to the amounts recognized in the Statements of Financial Condition and is not represented by the contract or notional amounts of the instruments. The Partnership’s and the Master’s risk of loss is reduced through the use of legally enforceable master netting agreements with counterparties that permit the Partnership and the Master to offset unrealized gains and losses and other assets and liabilities with such counterparties upon the occurrence of certain events. The Partnership and the Master had credit risk and concentration risk during the three months ended March 31, 2014 and in prior periods included in this report, as CGM and/or MS&Co. or their affiliates were the sole counterparties or brokers with respect to the Partnership’s and the Master’s assets. Credit risk with respect to exchange-traded instruments is reduced to the extent that, through CGM and/or MS&Co, the Partnership’s and the Master’s counterparty is an exchange or clearing organization. The Partnership and the Master continue to be subject to such risks with respect to MS&Co.
	The General Partner monitors and attempts to control the Partnership’s and the 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 and the Master may be subject. These monitoring systems generally allow the General Partner to statistically analyze actual trading results with risk-adjusted performance indicators and correlation statistics. In addition, online monitoring systems provide account analysis of futures, forwards and option contracts by sector, margin requirements, gain and loss transactions and collateral positions.
	The majority of these financial instruments mature within one year of the inception date. However, due to the nature of the Partnership’s and the Master’s business, these instruments may not be held to maturity.

Critical Accounting Policies	'
	7.    Critical Accounting Policies:
	Use of Estimates. The preparation of financial statements and accompanying notes in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, income and expenses, and related disclosures of contingent assets and liabilities in the financial statements and accompanying notes. As a result, actual results could differ from these estimates.
	Partnership’s and the Master’s Investments. All commodity interests held by the Partnership and the Master including derivative financial instruments and derivative commodity instruments are held for trading purposes. The commodity interests are recorded on the trade date and open contracts are recorded at fair value (as described below) at the measurement date. Investments in commodity interests denominated in foreign currencies are translated into U.S. dollars at the exchange rates prevailing at the measurement date. Gains or losses are realized when contracts are liquidated. Unrealized gains or losses on open contracts are included as a component of equity in commodity futures trading account on the Statements of Financial Condition. Net realized gains or losses and any change in net unrealized gains or losses from the preceding period are reported in the Statements of Income and Expenses and Changes in Partners’ Capital.
	Partnership’s and the Master’s Fair Value Measurements. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date under current market conditions. The fair value hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to fair values derived from unobservable inputs (Level 3). The level in the fair value hierarchy within which the fair value measurement falls in its entirety shall be determined based on the lowest level input that is significant to the fair value measurement in its entirety. Management has concluded that based on available information in the marketplace, the Master’s Level 1 assets and liabilities are actively traded.
	GAAP also requires the use of judgment in determining if a formerly active market has become inactive and in determining fair values when the market has become inactive. Management has concluded that based on available information in the marketplace, there has not been a significant decrease in the volume and level of activity in the Partnership’s Level 2 assets and liabilities.
	The Partnership and the Master will separately present purchases, sales, issuances and settlements in their reconciliation of Level 3 fair value measurements (i.e., to present such items on a gross basis rather than on a net basis), and make disclosures regarding the level of disaggregation as well as the inputs and valuation techniques used to measure fair value for measurements that fall within either Level 2 or Level 3 of the fair value hierarchy as required by GAAP.
	The Partnership and the Master consider prices for exchange-traded commodity futures, forward and option contracts to be based on unadjusted quoted prices in active markets for identical assets and liabilities (Level 1). The values of non-exchange-traded forward and option contracts for which market quotations are not readily available are priced by broker-dealers that derive fair values for those assets and liabilities from observable inputs (Level 2). Investments in the Master or (other commodity pools) where there are no other rights or obligations inherent within the ownership interest held by the Partnership are priced based on the end of the day net asset value (Level 2). The value of the Partnership’s investment in the Master reflects its proportional interest in the Master. As of and for the periods ended March 31, 2014 and December 31, 2013, the Partnership and the Master did not hold any derivative instruments that were priced at fair value using unobservable inputs through the application of management’s assumptions and internal valuation pricing models (Level 3). During the three months ended March 31, 2014 and for the twelve months ended December 31, 2013, there were no transfers of assets or liabilities between Level 1 and Level 2.
	Futures Contracts. The Master trades futures contracts. A futures contract is a firm commitment to buy or sell a specified quantity of investments, currency or a standardized amount of a deliverable grade commodity, at a specified price on a specified future date, unless the contract is closed before the delivery date or if the delivery quantity is something where physical delivery cannot occur (such as the S&P 500 Index), whereby such contract is settled in cash. Payments (“variation margin”) may be made or received by the Master each business day, depending on the daily fluctuations in the value of the underlying contracts, and are recorded as unrealized gains or losses by the Master. When the contract is closed, the Master record a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed. Transactions in futures contracts require participants to make both initial margin deposits of cash or other assets and variation margin deposits, through the futures broker, directly with the exchange on which the contracts are traded. Net realized gains (losses) and changes in net unrealized gains (losses) on futures contracts are included in the Statements of Income and Expenses and Changes in Partners’ Capital.
	Forward Foreign Currency Contracts. Forward foreign currency contracts are those contracts where the Master agrees to receive or deliver a fixed quantity of foreign currency for an agreed-upon price on an agreed future date. Forward foreign currency contracts are valued daily, and the Master’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. Net realized gains (losses) and changes in net unrealized gains (losses) on foreign currency contracts are recognized in the period in which the contract is closed or the changes occur, respectively, and are included in the Statements of Income and Expenses and Changes in Partners’ Capital.
	The Master does not isolate the portion of the results of operations arising from the effect of changes in foreign exchange rates on investments due to fluctuations from changes in market prices of investments held. Such fluctuations are included in net income (loss) on investments in the Statements of Income and Expenses and Changes in Partners’ Capital.
	London Metals Exchange Forward Contracts. Metal contracts traded on the London Metals Exchange (“LME”) represent a firm commitment to buy or sell a specified quantity of aluminum, copper, lead, nickel, tin or zinc. LME contracts traded by the Master are cash settled based on prompt dates published by the LME. Payments (“variation margin”) may be made or received by the Partnership and the Master each business day, depending on the daily fluctuations in the value of the underlying contracts, and are recorded as unrealized gains or losses by the Master. A contract is considered offset when all long positions have been matched with a like number of short positions settling on the same prompt date. When the contract is closed at the prompt date, the Master record a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed. Transactions in LME contracts require participants to make both initial margin deposits of cash or other assets and variation margin deposits, through the broker, directly with the LME. Net realized gains (losses) and changes in net unrealized gains (losses) on metal contracts are included in the Statements of Income and Expenses and Changes in Partners’ Capital.
	Investment Company Status. Effective January 1, 2014, the Partnership adopted, ASU 2013-08, “Financial Services — Investment Companies (Topic 946): Amendments to the Scope, Measurement and Disclosure Requirements.” ASU 2013-08 changes the approach to the investment company assessment, requires non-controlling ownership interests in other investment companies to be measured at fair value, and requires additional disclosures about the investment company’s status as an investment company. ASU 2013-08 is effective for interim and annual reporting periods beginning after December 15, 2013. The adoption of this ASU did not have a material impact on the Partnership’s financial statements. Based on management’s assessment, the Partnership has been deemed to be an investment company since inception. It has all of the fundamental characteristics of an investment company. Although, the Partnership does not possess all of the typical characteristics of an investment company, its activities are consistent with those of an investment company.
	Income Taxes. Income taxes have not been provided as each partner is individually liable for the taxes, if any, on its share of the Partnership’s income and expenses.
	GAAP provides guidance for how uncertain tax positions should be recognized, measured, presented and disclosed in the financial statements and requires the evaluation of tax positions taken or expected to be taken in the course of preparing the Partnership’s financial statements to determine whether the tax positions are “more-likely-than-not” to be sustained by the applicable tax authority. Tax positions with respect to tax at the Partnership level not deemed to meet the “more-likely-than-not” threshold would be recorded as a tax benefit or expense in the current year. The General Partner concluded that no provision for income tax is required in the Partnership’s financial statements.
	The Partnership files U.S. federal and various state and local tax returns. No income tax returns are currently under examination. The 2010 through 2013 tax years remain subject to examination by U.S. federal and most state tax authorities. The General Partner does not believe that there are any uncertain tax positions that require recognition of a tax liability.
	Net Income (Loss) per unit. Net income (loss) per unit is calculated in accordance with investment company guidance. See Note 2, “Financial Highlights.”
	Subsequent Events. The General Partner evaluates events that occur after the balance sheet date but before financial statements are issued. The General Partner has assessed the subsequent events through the date of issuance and determined that except as noted in Note 1 to the financial statements, there were no other subsequent events requiring adjustment of or disclosure in the financial statements.

During the three months ended March 31, 2014 and for the twelve months ended December 31, 2013, there were no transfers of assets or liabilities between Level 1 and Level 2.
Futures Contracts	'
	Futures Contracts. The Master trades futures contracts. A futures contract is a firm commitment to buy or sell a specified quantity of investments, currency or a standardized amount of a deliverable grade commodity, at a specified price on a specified future date, unless the contract is closed before the delivery date or if the delivery quantity is something where physical delivery cannot occur (such as the S&P 500 Index), whereby such contract is settled in cash. Payments (“variation margin”) may be made or received by the Master each business day, depending on the daily fluctuations in the value of the underlying contracts, and are recorded as unrealized gains or losses by the Master. When the contract is closed, the Master record a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed. Transactions in futures contracts require participants to make both initial margin deposits of cash or other assets and variation margin deposits, through the futures broker, directly with the exchange on which the contracts are traded. Net realized gains (losses) and changes in net unrealized gains (losses) on futures contracts are included in the Statements of Income and Expenses and Changes in Partners’ Capital.
Forward Foreign Currency Contracts	'
	Forward Foreign Currency Contracts. Forward foreign currency contracts are those contracts where the Master agrees to receive or deliver a fixed quantity of foreign currency for an agreed-upon price on an agreed future date. Forward foreign currency contracts are valued daily, and the Master’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. Net realized gains (losses) and changes in net unrealized gains (losses) on foreign currency contracts are recognized in the period in which the contract is closed or the changes occur, respectively, and are included in the Statements of Income and Expenses and Changes in Partners’ Capital.
	The Master does not isolate the portion of the results of operations arising from the effect of changes in foreign exchange rates on investments due to fluctuations from changes in market prices of investments held. Such fluctuations are included in net income (loss) on investments in the Statements of Income and Expenses and Changes in Partners’ Capital.
London Metals Exchange Forward Contracts	'
	London Metals Exchange Forward Contracts. Metal contracts traded on the London Metals Exchange (“LME”) represent a firm commitment to buy or sell a specified quantity of aluminum, copper, lead, nickel, tin or zinc. LME contracts traded by the Master are cash settled based on prompt dates published by the LME. Payments (“variation margin”) may be made or received by the Partnership and the Master each business day, depending on the daily fluctuations in the value of the underlying contracts, and are recorded as unrealized gains or losses by the Master. A contract is considered offset when all long positions have been matched with a like number of short positions settling on the same prompt date. When the contract is closed at the prompt date, the Master record a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed. Transactions in LME contracts require participants to make both initial margin deposits of cash or other assets and variation margin deposits, through the broker, directly with the LME. Net realized gains (losses) and changes in net unrealized gains (losses) on metal contracts are included in the Statements of Income and Expenses and Changes in Partners’ Capital.
Investment Company Status	'
	Investment Company Status. Effective January 1, 2014, the Partnership adopted, ASU 2013-08, “Financial Services — Investment Companies (Topic 946): Amendments to the Scope, Measurement and Disclosure Requirements.” ASU 2013-08 changes the approach to the investment company assessment, requires non-controlling ownership interests in other investment companies to be measured at fair value, and requires additional disclosures about the investment company’s status as an investment company. ASU 2013-08 is effective for interim and annual reporting periods beginning after December 15, 2013. The adoption of this ASU did not have a material impact on the Partnership’s financial statements. Based on management’s assessment, the Partnership has been deemed to be an investment company since inception. It has all of the fundamental characteristics of an investment company. Although, the Partnership does not possess all of the typical characteristics of an investment company, its activities are consistent with those of an investment company.
Income Taxes	'
	Income Taxes. Income taxes have not been provided as each partner is individually liable for the taxes, if any, on its share of the Partnership’s income and expenses.
	GAAP provides guidance for how uncertain tax positions should be recognized, measured, presented and disclosed in the financial statements and requires the evaluation of tax positions taken or expected to be taken in the course of preparing the Partnership’s financial statements to determine whether the tax positions are “more-likely-than-not” to be sustained by the applicable tax authority. Tax positions with respect to tax at the Partnership level not deemed to meet the “more-likely-than-not” threshold would be recorded as a tax benefit or expense in the current year. The General Partner concluded that no provision for income tax is required in the Partnership’s financial statements.
	The Partnership files U.S. federal and various state and local tax returns. No income tax returns are currently under examination. The 2010 through 2013 tax years remain subject to examination by U.S. federal and most state tax authorities. The General Partner does not believe that there are any uncertain tax positions that require recognition of a tax liability.
Subsequent Events	'
	Subsequent Events. The General Partner evaluates events that occur after the balance sheet date but before financial statements are issued. The General Partner has assessed the subsequent events through the date of issuance and determined that except as noted in Note 1 to the financial statements, there were no other subsequent events requiring adjustment of or disclosure in the financial statements.
Net Income (Loss) per unit	'
	Net Income (Loss) per unit. Net income (loss) per unit is calculated in accordance with investment company guidance. See Note 2, “Financial Highlights.”
