	1.    General:
	Orion Futures Fund L.P. (the “Partnership”), is a limited partnership organized on March 22, 1999, under the partnership laws of the State of New York to engage, directly or indirectly, in the speculative trading of a diversified portfolio of commodity interests, including futures contracts, options, swaps and forward contracts. The sectors traded include currencies, energy, grains, livestock, lumber, indices, U.S. and non-U.S. interest rates, softs and metals. The commodity interests that are traded by the Partnership and the Funds (as defined in Note 5, “Investment in Funds”) are volatile and involve a high degree of market risk. The Partnership commenced trading on June 10, 1999. The Partnership privately and continuously offers redeemable units of limited partnership interest (“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 are made for the Partnership by Transtrend B.V. (“Transtrend”), Winton Capital Management Limited (“Winton”) and AAA Capital Management Advisors, Ltd. (“AAA”) (each an “Advisor” and, collectively, the “Advisors”), each of which is a registered commodity trading advisor. Each Advisor is allocated a portion of the Partnership’s assets to manage. The Partnership invests the portion of its assets allocated to each of the Advisors indirectly through investments in master funds. In addition, the General Partner may allocate the Partnership’s assets to additional non-major trading advisors (i.e., commodity trading advisors intended to be allocated less than 10% of the Partnership’s assets). Information about advisors allocated less than 10% of the Partnership’s assets may not be disclosed.
	During the three months ended March 31, 2014, the Partnership’s/Funds’ 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, CMF Winton Master L.P. (“Winton Master”) entered into a foreign exchange brokerage account agreement with MS&Co., a registered futures commission merchant. During the third quarter of 2013, Winton Master also entered into a futures brokerage account agreement with MS&Co. Winton Master commenced foreign exchange trading through accounts at MS&Co. on or about May 1, 2013 and Winton Master commenced futures trading through an account at MS&Co. on or about July 22, 2013. During the third quarter of 2013, AAA Master LLC (“AAA Master”) entered into a futures brokerage account agreement with MS&Co. and commenced futures trading through an account at MS&Co. on or about September 9, 2013. Morgan Stanley Smith Barney TT II, LLC (“Transtrend Master”) continues to be party to a futures brokerage account agreement with MS&Co. Effective October 29, 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. As of October 29, 2013, the Partnership ceased paying a brokerage commission to CGM and began paying a brokerage commission to MS&Co. equal to (i) $18.00 per round-turn on futures transactions, up to an equivalent amount for swaps and $9.00 per side on options transactions for Class A units, and (ii) $3.00 per round-turn on futures transactions, up to an equivalent amount for swaps and $1.50 per side on options transactions for Class Z units. The brokerage commissions were inclusive of applicable floor brokerage fees. Also effective October 29, 2013, the Partnership entered into a selling agreement with Morgan Stanley Smith Barney LLC (d/b/a Morgan Stanley Wealth Management).
	Effective March 1, 2014, the Partnership entered into a new futures brokerage account agreement with MS&Co. and ceased paying brokerage commissions to MS&Co. Effective that same date, the Partnership terminated its existing selling agent agreement and entered into a new selling agreement with Morgan Stanley Wealth Management (the “Selling Agreement”). Pursuant to the Selling Agreement, Morgan Stanley Wealth Management receives a monthly selling agent fee, the amount of which is calculated by multiplying (i) the Partnership’s round turn futures transactions by $18.00 each, swaps by up to an equivalent amount and options transactions by $9.00 each per side for Class A units and (ii) the Partnership’s round turn futures transactions by $3.00 each, swaps by up to an equivalent amount and options transactions by $1.50 each per side for Class Z units. The ongoing selling agent fee amount is reduced by applicable floor brokerage. Morgan Stanley Wealth Management pays a portion of its ongoing selling agent fees to other properly licensed and/or registered selling agents and to financial advisers who have sold Redeemable Units in the Partnership.
	The Partnership, through its investment in the Funds, will pay MS&Co. trading fees for the clearing and, where applicable, execution of transactions.
	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 commissions.
	On June 1, 2011, the Partnership began offering “Class A” Redeemable Units and “Class Z” Redeemable Units pursuant to the offering memorandum. All Redeemable Units issued prior to June 1, 2011, were deemed Class A Redeemable Units. The rights, powers, duties and obligations associated with investment in Class A Redeemable Units were not changed. On August 1, 2011, Class Z Redeemable Units were first issued to certain employees of Morgan Stanley Smith Barney LLC and its affiliates (and their family members). Class A Redeemable Units and Class Z Redeemable Units will each be referred to as a “Class” and collectively referred to as the “Classes.” The Class of Redeemable Units that a limited partner receives upon a subscription will generally depend upon the status of the limited partner, although the General Partner may determine to offer Redeemable Units to investors at its discretion.
	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 the General Partner, 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 the General Partner 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.
	In May 2013, the General Partner discovered an overstatement of brokerage commissions for the Partnership occurring during the period from June 2011 to March 2013 (the “Time Period”). As a result, the General Partner contributed the amount of the overstatement, $14,069,403, to the Partnership. This contribution was applied to current limited partners of the Partnership as well as former limited partners whose redemption proceeds were impacted by the overstatement. The Statements of Changes in Partners’ Capital reflects an allocation from the General Partner of $12,227,974 for the then current limited partners. The impact of the overstatement on the financial statements during the Time Period was not considered material.

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. However, the Partnership’s investments are in other funds. The results of the Partnership’s trading activities resulting from its investments in the Funds are shown in the Statements of Income and Expenses.
	The customer agreement among the Partnership, the Funds and MS&Co. gives, and the Customer Agreements between the Partnership, the Funds and CGM gave, the Partnership and the Funds the legal right to net unrealized gains and losses on open futures, exchange-cleared swaps and open forward contracts. The Partnership and the Funds net, for financial reporting purposes, the unrealized gains and losses on open futures, exchange-cleared swaps and open forward contracts on the Statements of Financial Condition as the criteria under Accounting Standards Codification (“ASC”) 210 - 20, “Balance Sheet,” have been met.
	Brokerage commissions previously paid to CGM and MS&Co. were, and selling agent fees paid to MS&Co are, based on the number of trades executed by the Advisors and the Partnership’s ownership of the Funds.
	Trading and transaction fees are based on the number of trades executed by the Advisors for the Funds.

Fair_Value_Measurements

Fair Value Measurements	3 Months Ended

Fair Value Measurements	'
	4.    Fair Value Measurements:
	Partnership’s and the Funds’ Investments. All commodity interests held by the Partnership and the Funds, 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 gains or losses from the preceding period are reported in the Statements of Income and Expenses.
	Partnership’s and the Funds’ 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 Partnership’s and the Funds’ 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 markets 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 and the Funds’ Level 2 assets and liabilities.
	The Partnership and the Funds 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 Accounting Standards Update (“ASU”) 2012-04, “Technical Corrections and Improvements,” which makes minor technical corrections and clarifications to 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/Funds consider prices for exchange-traded commodity futures, forward, swaps and options 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, swaps and options 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 funds (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 investments in the Funds reflects its proportional interest in the Funds. As of and for the periods ended March 31, 2014, and December 31, 2013, the Partnership and the Funds did not hold any derivative instruments that were priced at fair value using unobservable inputs through the application of the management’s assumptions and internal valuation pricing models (Level 3). During the three months ended March 31, 2014 and the twelve months ended December 31, 2013, there were no transfers of assets or liabilities between Level 1 and Level 2.

	5.    Investment in Funds:
	On September 1, 2001, the assets allocated to AAA for trading were invested in AAA Master, a limited liability company organized under the limited liability company laws of the State of New York. The Partnership purchased 5,173.4381 units of AAA Master with cash equal to $5,173,438. AAA Master permits accounts managed by AAA using the Energy Program – Futures and Swaps, a proprietary, discretionary trading system, to invest together in one trading vehicle. The General Partner is also the managing member of AAA Master. Individual and pooled accounts currently managed by AAA, including the Partnership, are permitted to be non-managing members of AAA Master. The General Partner and AAA believe that trading through this structure should promote efficiency and economy in the trading process.
	On November 1, 2004, the assets allocated to Winton for trading were invested in Winton Master, a limited partnership organized under the partnership laws of the State of New York. The Partnership purchased 35,389.8399 units of Winton Master with cash equal to $33,594,083 and a contribution of open commodity futures and forward contracts with a fair value of $1,795,757. Winton Master permits accounts managed by Winton using the Diversified Program as applied without equities, a proprietary, systematic trading system, to invest together in one trading vehicle. The General Partner is also the general partner of Winton Master. Individual and pooled accounts currently managed by Winton, including the Partnership, are permitted to be limited partners of Winton Master. The General Partner and Winton believe that trading through this structure should promote efficiency and economy in the trading process. The General Partner and Winton have agreed that Winton will trade the Partnership’s assets allocated to Winton at a level that is up to 1.5 times the amount of the assets allocated.
	On June 1, 2011, the Partnership allocated a portion of its assets, with cash equal to $384,370,435 to Transtrend Master, a limited liability company organized under the limited liability company laws of the State of Delaware. Transtrend Master permits accounts managed by Transtrend using the Diversified Trend Program-Enhanced Risk Profile (US Dollar), a proprietary, systematic trading system, to invest together in one trading vehicle. The General Partner is also the trading manager of Transtrend Master. Individual and pooled accounts managed by Transtrend, including the Partnership are permitted to be non-managing members of Transtrend Master. The General Partner and Transtrend believe that trading through this structure should promote efficiency and economy in the trading process.
	The General Partner is not aware of any material changes to any of the trading programs discussed above during the fiscal quarter ended March 31, 2014.
	AAA Master’s, Transtrend Master’s and Winton Master’s (collectively, the “Funds”) trading of futures, forwards, swaps and options contracts, if applicable, on commodities is done primarily on U.S. commodity exchanges and foreign commodity exchanges. During the three months ended March 31, 2014, the Funds engaged in such trading through commodity brokerage accounts maintained with MS&Co. During prior periods included in this report, the Funds also engaged in such trading through commodity brokerage accounts maintained with CGM.
	A limited partner/non-managing member of the Funds may withdraw all or part of its capital contribution and undistributed profits, if any, from the Funds in multiples of the net asset value per unit as of the end of any day (the “Redemption Date”) after a request 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/non-managing member elects to redeem and informs the Funds.
	Management, administrative and incentive fees are charged at the Partnership level, except for fees payable to Transtrend which are charged at the Transtrend Master level. All trading, exchange, clearing, user, give-up, and National Futures Association fees (collectively the “clearing fees”) are borne by the Funds and allocated to their limited partners/non-managing members, including the Partnership. All other fees are charged at the Partnership level.
	At March 31, 2014, the Partnership owned approximately 47.5% of AAA Master, 95.9% of Transtrend Master and 68.6% of Winton Master. At December 31, 2013, the Partnership owned approximately 48.1% of AAA Master, 95.1% of Transtrend Master and 67.3% of Winton Master. It is the Partnership’s intention to continue to invest in the Funds. The performance of the Partnership is directly affected by the performance of the Funds. Expenses to investors as a result of the investment in the Funds are approximately the same and redemption rights are not affected.

Financial Instrument Risks	'
	6.    Financial Instrument Risks:
	In the normal course of 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 balances, 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, a swap execution facility or over-the-counter (“OTC”). Exchange-traded instruments include futures and certain standardized forwards, options and swap contracts. Certain swap contracts may also be traded on a swap execution facility or OTC. OTC contracts are negotiated between contracting parties and also include swaps and certain forward and option contracts. Specific market movements of commodities or futures contracts underlying on option cannot accurately be 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 16.3% to 22.9% of the Fund’s contracts are traded OTC.
	The risk to the limited partners that have purchased Redeemable Units is limited to the amount of 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 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. The Funds are exposed to a 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/Funds’ 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/Funds’ risk of loss is reduced through the use of legally enforceable master netting agreements with counterparties that permit the Partnership/Funds to offset unrealized gains and losses and other assets and liabilities with such counterparties upon the occurrence of certain events. The Partnership/Funds had credit risk and concentration risk during the reporting period and prior periods included in this report, as MS&Co. and/or CGM or their affiliates were the sole counterparties or brokers with respect to the Partnership and the Funds assets. Credit risk with respect to exchange-traded instruments is reduced to the extent that, through MS&Co. or CGM, the Partnership’s/Funds’ counterparty is an exchange or clearing organization. The Partnership/Funds continue to be subject to such risks with respect to MS&Co.
	As both a buyer and seller of options, the Funds pay or receive a premium at the outset and then bears the risk of unfavorable changes in the price of the contract underlying the option. Written options expose the Funds to potentially unlimited liability; for purchased options, the risk of loss is limited to the premiums paid. Certain written put options permit cash settlement and do not require the option holder to own the reference asset. The Funds do not consider these contracts to be guarantees.
	Management monitors and attempts to control the Partnership’s/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 may be subject. These monitoring systems generally allow management to statistically analyze actual trading results with risk-adjusted performance indicators and correlation statistics. In addition, online monitoring systems provide account analysis of futures, exchange-cleared swaps, forwards and options 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 Funds’ businesses, these instruments may not be held to maturity.

	7.    Critical Accounting Policies:
	Use of Estimates. The preparation of financial statements and accompanying notes in conformity with GAAP requires the General Partner 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 Funds’ Investments. All commodity interests held by the Partnership and the Funds, 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 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.
	Partnership’s and the Funds’ 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 Partnership’s and the Funds’ 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 markets 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 and the Funds’ Level 2 assets and liabilities.
	The Partnership and the Funds 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 under GAAP.
	The Partnership and the Funds consider prices for exchange-traded commodity futures, forwards, swaps and options 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 certain options 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 funds (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 investments in the Funds reflects its proportional interest in the Funds. As of and for the periods ended March 31, 2014 and December 31, 2013, the Partnership and the Funds did not hold any derivative instruments that were priced at fair value using unobservable inputs through the application of the management’s assumptions and internal valuation pricing models (Level 3). During the three months ended March 31, 2014, and the twelve months ended December 31, 2013, there were no transfers of assets or liabilities between Level 1 and Level 2.
	Futures Contracts. The Funds trade futures contracts and exchange-cleared swaps. Exchange-cleared swaps are swaps that are traded as futures. 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 Funds 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 Funds. When the contract is closed, the Funds 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.
	Forward Foreign Currency Contracts. Forward foreign currency contracts are those contracts where the Funds agree to receive or deliver a fixed quantity of foreign currency for an agreed-upon price on an agreed upon future date. Forward foreign currency contracts are valued daily, and the Funds’ 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.
	The Funds do not isolate the portion of the results of operations arising from the effect of changes in foreign exchange rates on investments from fluctuations due to changes in market prices of investments held. Such fluctuations are included in net income (loss) in the Statements of Income and Expenses.
	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 Funds are cash settled based on prompt dates published by the LME. Payments (“variation margin”) may be made or received by the Funds 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 Funds. 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 Funds 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.
	Options. The Funds may purchase and write (sell) both exchange-listed and OTC options on commodities or financial instruments. An option is a contract allowing, but not requiring, its holder to buy (call) or sell (put) a specific or standard commodity or financial instrument at a specified price during a specified time period. The option premium is the total price paid or received for the option contract. When the Funds write an option, the premium received is recorded as a liability in the Statements of Financial Condition and marked to market daily. When the Funds purchase an option, the premium paid is recorded as an asset in the Statements of Financial Condition and marked to market daily. Net realized gains (losses) and changes in net unrealized gains (losses) on options contracts are included in the Statements of Income and Expenses.
	Ongoing Selling Agent Fees. Ongoing selling agent fees to open and close futures and exchange-cleared swap contracts were expensed at the time the positions were opened. Ongoing selling agent fees on option contracts were expensed at the time the position was established and when the option contract was closed.
	Investment Company Status. Effective January 1, 2014, the Partnership adopted, ASU (“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 and typical characteristics 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 there were no subsequent events requiring adjustment of or disclosure in the financial statements.

When the contract is closed at the prompt date, the Funds 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.
Options	'
	Options. The Funds may purchase and write (sell) both exchange-listed and OTC options on commodities or financial instruments. An option is a contract allowing, but not requiring, its holder to buy (call) or sell (put) a specific or standard commodity or financial instrument at a specified price during a specified time period. The option premium is the total price paid or received for the option contract. When the Funds write an option, the premium received is recorded as a liability in the Statements of Financial Condition and marked to market daily. When the Funds purchase an option, the premium paid is recorded as an asset in the Statements of Financial Condition and marked to market daily. Net realized gains (losses) and changes in net unrealized gains (losses) on options contracts are included in the Statements of Income and Expenses.
Ongoing Selling Agent Fees	'
	Ongoing Selling Agent Fees. Ongoing selling agent fees to open and close futures and exchange-cleared swap contracts were expensed at the time the positions were opened. Ongoing selling agent fees on option contracts were expensed at the time the position was established and when the option contract was closed.
Investment Company Status	'
	Investment Company Status. Effective January 1, 2014, the Partnership adopted, ASU (“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 and typical characteristics 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 there were no 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.”
