Organization, Consolidation and Presentation of Financial Statements [Abstract]
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 three classes, Class A, B and I, 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, Inc. (“General Partner”), is the general partner of the Fund and a Maryland corporation 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. The three 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 and 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). During 2017, the Fund introduced a fourth class of units, R Units. Class R Units do not pay selling compensation or servicing fees to Selling Agents, and are generally intended for clients of Registered Investment Advisors. During 2014, the Fund purchased $58.5 million of Class I shares of the Steben Managed Futures Strategy Fund (“SMFSF”). 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 management investment company. SMFSF issues four classes of shares: Class A, C, I and N. At December 31, 2016, the Fund owned 60% of the outstanding shares of SMFSF and therefore had effective control of that entity. Accordingly, the assets, liabilities and operating results of SMFSF have been consolidated with the Fund. The portion of SMFSF that is not owned by the Fund is presented as the non-controlling interest. SMFSF has a similar investment strategy to the Fund, using trading advisors to engage in the speculative trading of futures contracts, forward currency contracts and other financial instruments. Prior to March 2016, SMFSF used a total return swap to gain access to the gains and losses of a basket of trading advisors. The General Partner serves as the investment manager of SMFSF. During 2016, the Fund redeemed $6 million of its investment in SMFSF, which is eliminated in consolidation. Significant Accounting Policies Accounting Principles The Fund’s consolidated financial statements are prepared in conformity with U.S. generally accepted accounting principles (“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 The accompanying consolidated financial statements include the accounts of the Fund and SMFSF, for which the Fund was the majority shareholder. Intercompany accounts and transactions have been eliminated in consolidation. Use of Estimates Preparing consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. Revenue Recognition Futures, forward currency contracts, investments in securities, and certificates of deposit 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 consolidated statements of operations. Unrealized gains and losses on open contracts (the difference between contract trade price and fair value) are reported in the consolidated 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 consolidated 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. 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 money market 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 U.S. government sponsored enterprise notes. 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, 2016 and 2015, 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 U.S. government sponsored enterprise notes 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 U.S. government sponsored enterprise notes are classified within Level 2. The investment in a money market fund, included in cash and cash equivalents in the consolidated statements of financial condition, and futures contracts, all of which are exchange-traded, are valued using quoted market prices for identical assets 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. The fair value of the swap investment is based on quoted market prices for the underlying contracts of the trading advisor programs within the swap and is 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. 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, 2016. 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 2013. 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 consolidated statements of operations. Swap Agreement Through its investment in SMFSF, the Fund had exposure to a total return swap with Deutsche Bank AG. This two-party contract was entered in to exchange, or swap, the returns realized on a basket of CTA programs. Under the terms of the swap agreement, the investment manager of SMFSF had the ability to periodically adjust the notional level of the swap, the notional allocation to each CTA program and the mix of CTA programs. The swap agreement was terminated in March 2016. At December 31, 2015, the notional value of the swap was $98,065,907. SMFSF had provided $12,796,500 as collateral, which was included in cash in broker trading accounts in the consolidated statements of financial condition. During the year ended December 31, 2016, the swap had appreciation in fair value of $5,265,762 and during the year ended December 31, 2015, the swap had an depreciation in fair value of $4,630,918. Amounts are included in net change in unrealized gain (loss) on futures, forwards and swap contracts in the consolidated statements of operations. Reclassification Certain amounts in the 2015 and 2014 consolidated financial statements have been reclassified to conform to the 2016 presentation without affecting previously reported partners’ capital (net asset value) or net income (loss). New Accounting Pronouncements Revenue from Contracts with Customers In May 2014, the FASB issued guidance that replaces the existing accounting standards for revenue recognition. The guidance provides a new model to determine when and over what period revenue is recognized. Under this new model, revenue is recognized as goods or services are delivered in an amount that reflects the consideration to be received. In March 2016, the FASB issued an Accounting Standards Update (“ASU”), Revenue from Contracts with Customers: Principal versus Agent Considerations (Reporting Revenue Gross versus Net) Revenue from Contracts with Customers: Identifying Performance Obligations and Licensing Revenue from Contracts with Customers: Narrow-Scope Improvements and Practical Expedient Consolidation In February 2015, the FASB issued guidance that amends prior consolidation analysis. The effect of the guidance is to modify the analysis performed to determine if an entity should be consolidated. The new guidance is effective for fiscal years beginning after December 15, 2016. The Fund does not expect any change as a result of adopting this guidance.

Subscriptions, Distributions and Redemptions	7. Subscriptions, Distributions and Redemptions Investments in the Fund are made by subscription agreement and must be received within five business days of the end of the month, subject to acceptance by the General Partner. The minimum investment is $10,000 for Class A and B units and $2,000,000 for Class I units. Units are sold at the respective net asset value per unit for Class A, B or I 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, 2016 and 2015, the Fund received advance subscriptions of $2,687,191 and $1,086,965, respectively, which were recognized as subscriptions to the Fund or returned, if applicable, subsequent to period-end.

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 and Société Générale International Limited (formerly Société Générale Newedge UK Limited) and UBG 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 consolidated 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, 2016.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Accounting Principles	Accounting Principles The Fund’s consolidated financial statements are prepared in conformity with U.S. generally accepted accounting principles (“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 The accompanying consolidated financial statements include the accounts of the Fund and SMFSF, for which the Fund was the majority shareholder. Intercompany accounts and transactions have been eliminated in consolidation.
Use of Estimates	Use of Estimates Preparing consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates.
Revenue Recognition	Revenue Recognition Futures, forward currency contracts, investments in securities, and certificates of deposit 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 consolidated statements of operations. Unrealized gains and losses on open contracts (the difference between contract trade price and fair value) are reported in the consolidated 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 consolidated 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.
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 money market 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 U.S. government sponsored enterprise notes. 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, 2016 and 2015, 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 U.S. government sponsored enterprise notes 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 U.S. government sponsored enterprise notes are classified within Level 2. The investment in a money market fund, included in cash and cash equivalents in the consolidated statements of financial condition, and futures contracts, all of which are exchange-traded, are valued using quoted market prices for identical assets 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. The fair value of the swap investment is based on quoted market prices for the underlying contracts of the trading advisor programs within the swap and is 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.
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, 2016. 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 2013.
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 consolidated statements of operations.
Swap Agreement	Swap Agreement Through its investment in SMFSF, the Fund had exposure to a total return swap with Deutsche Bank AG. This two-party contract was entered in to exchange, or swap, the returns realized on a basket of CTA programs. Under the terms of the swap agreement, the investment manager of SMFSF had the ability to periodically adjust the notional level of the swap, the notional allocation to each CTA program and the mix of CTA programs. The swap agreement was terminated in March 2016. At December 31, 2015, the notional value of the swap was $98,065,907. SMFSF had provided $12,796,500 as collateral, which was included in cash in broker trading accounts in the consolidated statements of financial condition. During the year ended December 31, 2016, the swap had appreciation in fair value of $5,265,762 and during the year ended December 31, 2015, the swap had an depreciation in fair value of $4,630,918. Amounts are included in net change in unrealized gain (loss) on futures, forwards and swap contracts in the consolidated statements of operations.
Reclassification	Reclassification Certain amounts in the 2015 and 2014 consolidated financial statements have been reclassified to conform to the 2016 presentation without affecting previously reported partners’ capital (net asset value) or net income (loss).
New Accounting Pronouncements	New Accounting Pronouncements Revenue from Contracts with Customers In May 2014, the FASB issued guidance that replaces the existing accounting standards for revenue recognition. The guidance provides a new model to determine when and over what period revenue is recognized. Under this new model, revenue is recognized as goods or services are delivered in an amount that reflects the consideration to be received. In March 2016, the FASB issued an Accounting Standards Update (“ASU”), Revenue from Contracts with Customers: Principal versus Agent Considerations (Reporting Revenue Gross versus Net) Revenue from Contracts with Customers: Identifying Performance Obligations and Licensing Revenue from Contracts with Customers: Narrow-Scope Improvements and Practical Expedient Consolidation In February 2015, the FASB issued guidance that amends prior consolidation analysis. The effect of the guidance is to modify the analysis performed to determine if an entity should be consolidated. The new guidance is effective for fiscal years beginning after December 15, 2016. The Fund does not expect any change as a result 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, B or I 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 consolidated 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 consolidated statements of operations. The resulting amount is divided by the average net asset value for the period.
[3]	Ratio excludes General Partner 1% allocation.
