Organization and Summary of Significant Accounting Policies	1. Organization and Summary of Significant Accounting Policies Description of the Fund Futures Portfolio Fund, Limited Partnership (“Fund”) is a Maryland limited partnership, which operates as a commodity investment pool that commenced trading operations on January 2, 1990. The Fund issues units of limited partner interests (“Units”) in six classes, Class A, A2, A3, B, I and R, which represent units of fractional undivided beneficial interest in and ownership of the Fund. The Fund will automatically terminate on December 31, 2025, unless terminated earlier as provided in the Third Amended and Restated Limited Partnership Agreement (“Partnership Agreement”). The Fund uses commodity trading advisors to engage in the speculative trading of futures contracts, forward currency contracts and other financial instruments traded in the United States (“U.S.”) and internationally. The Fund is a registrant with the U.S. Securities and Exchange Commission (“SEC”) pursuant to the U.S. Securities Exchange Act of 1934, as amended (“1934 Act”). As a registrant, the Fund is subject to the regulations of the SEC and the disclosure requirements of the 1934 Act. As a commodity pool, the Fund is subject to the regulations of the U.S. Commodity Futures Trading Commission (“CFTC”), an agency of the U.S. Government, which regulates most aspects of the commodity futures industry; rules of the National Futures Association (“NFA”), an industry self-regulatory organization; rules of Financial Industry Regulatory Authority (“FINRA”), an industry self-regulatory organization; and the requirements of commodity exchanges where the Fund executes transactions. Additionally, the Fund is subject to the requirements of the futures brokers and interbank market makers through which the Fund trades. Steben & Company, LLC (“General Partner”), is the general partner of the Fund and a Maryland limited liability company registered with the CFTC as a commodity pool operator and a commodities introducing broker, and is also registered with the SEC as a registered investment advisor and a broker dealer. The General Partner is a member of the NFA and FINRA. The General Partner manages all aspects of the Fund’s business and serves as one of the Fund’s selling agents. On October 31, 2019, Octavus Group, LLC acquired all of the stock of the General Partner. Octavus Group is the parent company of LoCorr Fund Management LLC, which serves as the investment advisor to multiple alternative investment mutual funds. LoCorr Fund Management LLC operates alternative investment funds with a low correlation to traditional asset classes. The six classes of Units in the Fund differ only in the fees applicable to each class. Class A Units are subject to a 2% per annum selling agent fee. Class A2 Units may pay an up-front sales commission of up to 3% of the offering price and a 0.6% per annum selling agent fee. Class A3 Units may pay an up-front sales commission of up to 2% of the offering price and a 0.75% per annum selling agent fee. Class B Units are subject to a 0.2% per annum broker dealer servicing fee. Class I Units are subject to higher minimum investments requirements and lower General Partner management fees (0.75% per annum instead of 1.50% per annum) as well as a General Partner performance fee (7.5% of new profits, described more fully in Footnote 4). Class R Units do not pay selling compensation or servicing fees to selling agents and are generally intended for clients of registered investment advisors. Class R Units were introduced in March 2017, and on April 1, 2017, approximately $14 million in Class B Units transferred to R Units. Class A2 and A3 Units were introduced in June 2017. At December 31, 2019, the Fund owned approximately $22 million of Class I shares of the Steben Managed Futures Strategy Fund (“SMFSF”), which represents approximately 38% of that fund. SMFSF is a non-diversified series of shares of beneficial interest of Steben Alternative Investment Fund (the “Trust”), a statutory trust organized under the laws of the State of Delaware, and is registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as an open-end investment company. SMFSF has a similar investment strategy to the Fund, using commodity trading advisors to engage in the speculative trading of futures contracts, forward currency contracts and other financial instruments. Prior to August 31, 2017, the Fund owned more than 50% of the outstanding shares of SMFSF and therefore had effective control of that entity. Accordingly, the assets, liabilities and operating results of SMFSF were consolidated with the Fund through that date. The portion of SMFSF that was not owned by the Fund was presented as the non-controlling interest. On August 31, 2017, the Fund’s ownership of SMFSF dropped below 50%. With this decrease in ownership, the Fund no longer has effective control of SMFSF, and effective August 31, 2017 no longer consolidates the assets, liabilities and operating results of SMFSF into the Fund. The Fund continues to hold an investment in SMFSF and any changes in the fair value of its investment in SMFSF are reported on the Statement of Operations. The investment in SMFSF is reported on the statements of financial condition as investment in SMFSF. For financial reporting purposes, SMFSF is treated as a related party. For the years ended December 31, 2019 and 2018, the Fund redeemed $6 million and $5 million, respectively, of its investment in SMFSF. In January 2020 SMFSF was merged into the LoCorr Macro Strategies Fund and the Fund fully redeemed its investment following the merger. Significant Accounting Policies Accounting Principles The Fund’s financial statements are prepared in conformity with U.S. generally accepted accounting principles (“GAAP”). Under GAAP, the Fund is an investment company and follows accounting and reporting guidance under the Financial Accounting Standards Board (FASB) Accounting Standard Codification (ASC) Topic 946, Financial Services – Investment Companies Consolidation Through August 31, 2017, the accompanying financial statements included the accounts of the Fund and SMFSF, for which the Fund was the majority shareholder. On August 31, 2017, the Fund ceased being the majority shareholder of SMFSF and no longer consolidates that entity into its financial statements. Intercompany accounts and transactions have been eliminated in consolidation. Use of Estimates Preparing financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Revenue Recognition Futures, forward currency contracts, investments in securities, certificates of deposit, and the exchange membership are recorded on a trade date basis, and gains or losses are realized when contracts/positions are liquidated. Realized gains and losses on investments in securities and certificates of deposit are determined on a specific identification basis and are included in net realized and change in unrealized gain (loss) in the statements of operations. Unrealized gains and losses on open contracts (the difference between contract trade price and fair value) are reported in the statements of financial condition as net unrealized gain or loss, as there exists a right of offset of any unrealized gains or losses. The difference between cost and the fair value of open investments in securities and certificates of deposit is reflected as unrealized gain or loss on investments in securities and certificates of deposit. Any change in net unrealized gain or loss from the preceding period is reported in the statements of operations. Interest income earned on investments in securities, certificates of deposit and other cash and cash equivalent balances is recorded on an accrual basis. Market discounts and premiums on fixed-income securities are amortized daily over the expected life of the security using the effective yield method. Fair Value of Financial Instruments Financial instruments are recorded at fair value, the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. Assets and liabilities recorded at fair value are classified within a fair value hierarchy based upon the level of judgment associated with the inputs used to measure their value. This fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The three levels of the fair value hierarchy are described below: Level 1 – Fair value is based on unadjusted quoted prices for identical instruments in active markets. Financial instruments utilizing Level 1 inputs include futures contracts, U.S. Treasury securities and mutual funds. Level 2 – Fair value is based on quoted prices for similar instruments in active markets and inputs other than quoted prices that are observable for the financial instrument, such as interest rates and yield curves that are observable at commonly quoted intervals using a market approach. Financial instruments utilizing Level 2 inputs include forward currency contracts, swaps, commercial paper, corporate notes, certificates of deposit, asset backed securities and the exchange membership. Level 3 – Fair value is based on valuation techniques in which one or more significant inputs are unobservable. The Fund has no financial instruments utilizing Level 3 inputs. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, an instrument’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. The Fund’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the investment. The Fund assesses the classification of the instruments at each measurement date, and any transfers between levels are recognized on the actual date of the event or change in circumstances that caused the transfer in accordance with the Fund’s accounting policy regarding the recognition of transfers between levels of the fair value hierarchy. For the years ended December 31, 2019 and 2018, there were no such transfers between levels. A description of the valuation techniques applied to the Fund’s major categories of assets and liabilities measured at fair value on a recurring basis follows. U.S. Treasury securities are recorded at fair value based on bid and ask quotes for identical instruments. Commercial paper, certificates of deposit, corporate notes, asset backed securities and the exchange membership are recorded at fair value based on bid and ask quotes for similar, but not identical, instruments. Accordingly, U.S. Treasury securities are classified within Level 1, and commercial paper, certificates of deposit, corporate notes, asset backed securities and exchange memberships are classified within Level 2. The investment in SMFSF (a mutual fund), a money market fund and futures contracts are valued using quoted market prices for identical assets in active markets and are classified within Level 1. The fair values of forward currency contracts are based upon third-party quoted dealer values on the interbank market and are classified within Level 2. Cash and Cash Equivalents Cash and cash equivalents may include cash, funds held in money market accounts and short-term investments with maturities of three months or less at the date of acquisition and that are not held for sale in the normal course of business. The Fund maintains deposits with financial institutions in amounts that are in excess of federally insured limits; however, the Fund does not believe it is exposed to any significant credit risk. Exchange Membership During 2017, the Fund purchased a membership interest in the Chicago Mercantile Exchange (CME). By purchasing the membership, the Fund will incur reduced fees for transactions on the CME. The membership is accounted at its fair value and changes in fair value are reported in net change in unrealized gain (loss) in exchange membership on the statement of operations. Brokerage Commissions and Trading Expenses Brokerage commissions and trading expenses include brokerage and other trading fees and are charged to expense when contracts are opened and closed. Redemptions Payable Redemptions payable represent redemptions that meet the requirements of the Fund and have been approved by the General Partner prior to year-end. These redemptions have been recorded using the year end net asset value per Unit. Income Taxes The Fund prepares calendar year U.S. and applicable state and local tax returns. The Fund is not subject to federal income taxes as each partner is individually liable for his or her allocable share of the Fund’s income, expenses and trading gains or losses. The Fund evaluates the tax positions taken or expected to be taken in the course of preparing the Fund’s tax returns to determine whether the tax positions are more-likely-than-not to be sustained when examined 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 and asset or liability in the current year. Management has determined there are no material uncertain income tax positions through December 31, 2019. With few exceptions, the Fund is no longer subject to U.S. federal, or state and local income tax examinations by tax authorities for years before 2016. Foreign Currency Transactions The Fund has certain investments denominated in foreign currencies. The purchase and sale of investments, and income and expenses are translated at the rates of exchange prevailing on the respective dates of such transactions. The Fund does not isolate that portion of the results of operations resulting from changes in foreign exchange rates on investments from the fluctuations arising from changes in market prices of investments held. Such fluctuations are included with the net realized and change in unrealized gain or loss on such investments in the statements of operations. Reclassification Certain amounts in the 2018 and 2017 financial statements may have been reclassified to conform to the 2019 presentation without affecting previously reported partners’ capital (net asset value) or net income (loss). New Accounting Pronouncements Fair Value Disclosures In August 2018, the FASB issued guidance updating the disclosure requirements for fair value measurement and the fair value hierarchy. Primarily, the guidance added or modified certain disclosures regarding Level 3 fair value measurements and removed certain disclosures involving transfers between Level 1 and Level 2 of the fair value hierarchy. Historically, the Fund has not had any Level 3 fair value measurements and has not had any transfers between Level 1 and Level 2 on the fair value hierarchy. The update is effective beginning after December 15, 2019, although early adoption is permitted. The Fund anticipates no impact of adopting this guidance.

The minimum investment is $10,000 for Class A, A2, A3, B and R units and $2,000,000 for Class I units. Units are sold at the respective net asset value per unit for Class A, A2, A3, B, I or R interests as of the close of business on the last day of the month in which the subscription is accepted. Investors whose subscriptions are accepted are admitted as limited partners as of the beginning of the month following the month in which their subscriptions were accepted. At December 31, 2019 and 2018, the Fund received advance subscriptions of $266,000 and $224,523, respectively, which were recognized as subscriptions to the Fund subsequent to period-end. The Fund is not required to make distributions but may do so at the sole discretion of the General Partner. A limited partner may request and receive redemption of Class A, A2, A3, B, I or R Units owned at the end of any month, subject to five business days’ prior written notice to the General Partner, and in certain circumstances, restrictions in the Partnership Agreement.

Trading Activities And Related Risks
Trading Activities and Related Risks	8. Trading Activities and Related Risks The Fund engages in the speculative trading of futures, options and over-the-counter contracts, including forward currency contracts traded in the U.S. and internationally. Trading in derivatives exposes the Fund to both market risk, the risk arising from a change in the fair value of a contract, and credit risk, the risk of failure by another party to perform according to the terms of a contract. Purchase and sale of futures contracts requires margin deposits with the futures brokers. Additional deposits may be necessary for any loss of contract value. The Commodity Exchange Act (“CEAct”) requires a broker to segregate all customer transactions and assets from such broker’s proprietary activities. A customer’s cash and other property (for example, U.S. Treasury securities) deposited with a broker are considered commingled with all other customer funds subject to the broker’s segregation requirements. In the event of a broker’s insolvency, recovery may be limited to a pro rata share of segregated funds available. It is possible that the recovered amount could be less than (or none of) the total cash and other property deposited. The Fund uses with SG Americas Securities, LLC, JP Morgan Securities, LLC, and Deutsche Bank Securities, Inc. as its futures brokers. The Fund uses Société Générale International Limited and Deutsche Bank AG as its forward currency counterparties. For futures contracts, risks arise from changes in the fair value of the contracts. Theoretically, the Fund is exposed to a market risk equal to the value of futures and forward currency contracts purchased, and unlimited liability on such contracts sold short. In addition to market risk, upon entering into commodity interest contracts there is a credit risk that a counterparty will not be able to meet its obligations to the Fund. The counterparty for futures and options on futures contracts traded in the U.S. and on most non-U.S. futures exchanges is the clearinghouse associated with such exchanges. In general, clearinghouses are backed by the corporate members of the clearinghouse who are required to share any financial burden resulting from the non-performance by one of their members and, as such, should significantly reduce this credit risk. In cases where the clearinghouse is not backed by the clearing members, like some non-U.S. exchanges, it is normally backed by a consortium of banks or other financial institutions. In the case of forward currency contracts, which are traded on the interbank or other institutional market rather than on exchanges, the counterparty is generally a single bank or other financial institution, rather than a clearinghouse backed by a group of financial institutions; thus there likely will be greater counterparty credit risk. While the Fund trades only with those counterparties that it believes to be creditworthy, there can be no assurance that any clearing member, clearinghouse or other counterparty will be able to meet its obligations to the Fund. The Fund trades forward currency contracts in unregulated markets between principals and assumes the risk of loss from counterparty non-performance. Accordingly, the risks associated with forward currency contracts are generally greater than those associated with exchange-traded contracts because of the greater risk of counterparty default. Additionally, the trading of forward currency contracts typically involves delayed cash settlement. The Fund has a portion of its assets on deposit with interbank market makers and other financial institutions in connection with its trading of forward currency contracts and its cash management activities. In the event of an interbank market maker’s or financial institution’s insolvency, recovery of Fund assets on deposit may be limited to account insurance or other protection afforded such deposits. Entering into swap agreements involves, to varying degrees, credit, market, and counterparty risk in excess of the amounts recognized on the statement of financial condition. The Cash Managers manage the Fund’s cash and excess margin through investments in fixed income instruments, pursuant to investment parameters established by the General Partner. Fluctuations in prevailing interest rates could cause mark-to-market losses on the Fund’s fixed income instruments. Through its investments in debt securities and certificates of deposit, the Fund has exposure to U.S. and foreign enterprises. The following table presents the exposure at December 31, 2019.

The Fund’s maximum exposure under these arrangements cannot be estimated. However, the Fund believes that it is unlikely it will have to make material payments under these arrangements and has not recorded any contingent liability in the financial statements for such indemnifications.

Discontinued Operations and Disposal Groups [Abstract]
Deconsolidation of Steben Managed Futures Strategy Fund	12. Deconsolidation of Steben Managed Futures Strategy Fund As of August 31, 2017, the Fund no longer has effective control of the financial and operating policies of SMFSF as it no longer owns a majority of the outstanding shares of that mutual fund. Accordingly, the Fund deconsolidated the related assets, liabilities and non-controlling interest in SMFSF on that date. The Fund did not receive any consideration in the deconsolidation of SMFSF and there was no gain or loss upon deconsolidation. The assets and liabilities which the Fund deconsolidated were: Assets August 31, 2017 Equity in broker trading accounts Cash $ 17,813,620 Net unrealized gain (loss) on open futures contracts 1,206,044 Net unrealized gain (loss) on open forward currency contracts 74,520 Total equity in broker trading accounts 19,094,184 Cash and cash equivalents 1,690,646 Investments in securities, at fair value 53,611,230 Subscription receivable 543,627 Liabilities Trading advisor management fees 112,367 Distribution (12b-1) fees payable 3,331 Operating services fee payable 15,410 Redemptions payable 35,760 Net assets deconsolidated 74,772,819 Less: non-controlling interest (38,169,976 ) Fair value of interest retained $ 36,602,843 On the statement of cash flows, the balance of cash and cash equivalents deconsolidated on August 31, 2017 was $19,504,266. On the statement of operations, the income and expenses incurred by SMFSF during the period of consolidation are recognized as income and expenses of the Fund pursuant to the principles of consolidation. Income and expenses incurred by SMFSF following deconsolidation on August 31, 2017 are not directly recognized by the Fund, but they do impact the net asset value of SMFSF and consequently the fair value of the Fund’s investment in SMFSF. Realized gains (losses) and changes in unrealized gains (losses) on the Fund’s investment in SMFSF following deconsolidation on August 31, 2017 are recognized on the Fund’s statement of operations.

Organization and Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2019
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Accounting Principles	Accounting Principles The Fund’s financial statements are prepared in conformity with U.S. generally accepted accounting principles (“GAAP”). Under GAAP, the Fund is an investment company and follows accounting and reporting guidance under the Financial Accounting Standards Board (FASB) Accounting Standard Codification (ASC) Topic 946, Financial Services – Investment Companies
Consolidation	Consolidation Through August 31, 2017, the accompanying financial statements included the accounts of the Fund and SMFSF, for which the Fund was the majority shareholder. On August 31, 2017, the Fund ceased being the majority shareholder of SMFSF and no longer consolidates that entity into its financial statements. Intercompany accounts and transactions have been eliminated in consolidation.
Use of Estimates	Use of Estimates Preparing financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.
Revenue Recognition	Revenue Recognition Futures, forward currency contracts, investments in securities, certificates of deposit, and the exchange membership are recorded on a trade date basis, and gains or losses are realized when contracts/positions are liquidated. Realized gains and losses on investments in securities and certificates of deposit are determined on a specific identification basis and are included in net realized and change in unrealized gain (loss) in the statements of operations. Unrealized gains and losses on open contracts (the difference between contract trade price and fair value) are reported in the statements of financial condition as net unrealized gain or loss, as there exists a right of offset of any unrealized gains or losses. The difference between cost and the fair value of open investments in securities and certificates of deposit is reflected as unrealized gain or loss on investments in securities and certificates of deposit. Any change in net unrealized gain or loss from the preceding period is reported in the statements of operations. Interest income earned on investments in securities, certificates of deposit and other cash and cash equivalent balances is recorded on an accrual basis. Market discounts and premiums on fixed-income securities are amortized daily over the expected life of the security using the effective yield method.
Fair Value of Financial Instruments	Fair Value of Financial Instruments Financial instruments are recorded at fair value, the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. Assets and liabilities recorded at fair value are classified within a fair value hierarchy based upon the level of judgment associated with the inputs used to measure their value. This fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The three levels of the fair value hierarchy are described below: Level 1 – Fair value is based on unadjusted quoted prices for identical instruments in active markets. Financial instruments utilizing Level 1 inputs include futures contracts, U.S. Treasury securities and mutual funds. Level 2 – Fair value is based on quoted prices for similar instruments in active markets and inputs other than quoted prices that are observable for the financial instrument, such as interest rates and yield curves that are observable at commonly quoted intervals using a market approach. Financial instruments utilizing Level 2 inputs include forward currency contracts, swaps, commercial paper, corporate notes, certificates of deposit, asset backed securities and the exchange membership. Level 3 – Fair value is based on valuation techniques in which one or more significant inputs are unobservable. The Fund has no financial instruments utilizing Level 3 inputs. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, an instrument’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. The Fund’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the investment. The Fund assesses the classification of the instruments at each measurement date, and any transfers between levels are recognized on the actual date of the event or change in circumstances that caused the transfer in accordance with the Fund’s accounting policy regarding the recognition of transfers between levels of the fair value hierarchy. For the years ended December 31, 2019 and 2018, there were no such transfers between levels. A description of the valuation techniques applied to the Fund’s major categories of assets and liabilities measured at fair value on a recurring basis follows. U.S. Treasury securities are recorded at fair value based on bid and ask quotes for identical instruments. Commercial paper, certificates of deposit, corporate notes, asset backed securities and the exchange membership are recorded at fair value based on bid and ask quotes for similar, but not identical, instruments. Accordingly, U.S. Treasury securities are classified within Level 1, and commercial paper, certificates of deposit, corporate notes, asset backed securities and exchange memberships are classified within Level 2. The investment in SMFSF (a mutual fund), a money market fund and futures contracts are valued using quoted market prices for identical assets in active markets and are classified within Level 1. The fair values of forward currency contracts are based upon third-party quoted dealer values on the interbank market and are classified within Level 2.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents may include cash, funds held in money market accounts and short-term investments with maturities of three months or less at the date of acquisition and that are not held for sale in the normal course of business. The Fund maintains deposits with financial institutions in amounts that are in excess of federally insured limits; however, the Fund does not believe it is exposed to any significant credit risk.
Exchange Membership	Exchange Membership During 2017, the Fund purchased a membership interest in the Chicago Mercantile Exchange (CME). By purchasing the membership, the Fund will incur reduced fees for transactions on the CME. The membership is accounted at its fair value and changes in fair value are reported in net change in unrealized gain (loss) in exchange membership on the statement of operations.
Brokerage Commissions and Trading Expenses	Brokerage Commissions and Trading Expenses Brokerage commissions and trading expenses include brokerage and other trading fees and are charged to expense when contracts are opened and closed.
Redemptions Payable	Redemptions Payable Redemptions payable represent redemptions that meet the requirements of the Fund and have been approved by the General Partner prior to year-end. These redemptions have been recorded using the year end net asset value per Unit.
Income Taxes	Income Taxes The Fund prepares calendar year U.S. and applicable state and local tax returns. The Fund is not subject to federal income taxes as each partner is individually liable for his or her allocable share of the Fund’s income, expenses and trading gains or losses. The Fund evaluates the tax positions taken or expected to be taken in the course of preparing the Fund’s tax returns to determine whether the tax positions are more-likely-than-not to be sustained when examined 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 and asset or liability in the current year. Management has determined there are no material uncertain income tax positions through December 31, 2019. With few exceptions, the Fund is no longer subject to U.S. federal, or state and local income tax examinations by tax authorities for years before 2016.
Foreign Currency Transactions	Foreign Currency Transactions The Fund has certain investments denominated in foreign currencies. The purchase and sale of investments, and income and expenses are translated at the rates of exchange prevailing on the respective dates of such transactions. The Fund does not isolate that portion of the results of operations resulting from changes in foreign exchange rates on investments from the fluctuations arising from changes in market prices of investments held. Such fluctuations are included with the net realized and change in unrealized gain or loss on such investments in the statements of operations.
Reclassification	Reclassification Certain amounts in the 2018 and 2017 financial statements may have been reclassified to conform to the 2019 presentation without affecting previously reported partners’ capital (net asset value) or net income (loss).
New Accounting Pronouncements	New Accounting Pronouncements Fair Value Disclosures In August 2018, the FASB issued guidance updating the disclosure requirements for fair value measurement and the fair value hierarchy. Primarily, the guidance added or modified certain disclosures regarding Level 3 fair value measurements and removed certain disclosures involving transfers between Level 1 and Level 2 of the fair value hierarchy. Historically, the Fund has not had any Level 3 fair value measurements and has not had any transfers between Level 1 and Level 2 on the fair value hierarchy. The update is effective beginning after December 15, 2019, although early adoption is permitted. The Fund anticipates no impact of adopting this guidance.

[1]	The net investment income (loss) per unit is calculated by dividing the net investment income (loss) by the average number of Class A, A2, B, I or R Units outstanding during the period. Net realized and change in unrealized gain (loss) on investments is a balancing amount necessary to reconcile the change in net asset value per unit with the other per unit information. Such balancing amount may differ from the calculation of net realized and change in unrealized gain (loss) on investment per unit due to the timing of investment gains and losses during the period relative to the number of units outstanding.
[2]	The net investment income (loss) includes interest income and excludes net realized and net change in unrealized gain (loss) from investment activities as shown in the statements of operations. The total amount is then reduced by all expenses, excluding brokerage commissions, which are included in net investment gain (loss) in the statements of operations. The resulting amount is divided by the average net asset value for the period.
[3]	Ratio excludes General Partner 1% allocation.
[4]	Class A2 Units were first purchased in December 2018. Total return for 2018 is for the period from first purchase to year end and is not annualized.
[5]	Class A3 units were first purchased in July 2019. The total return for 2019 is for the period from first purchase to year end and is not annualized.
[6]	Class R Units were first purchased in April 2017. Total return for 2017 is for the period from first purchase to year end and is not annualized.
