The investment objective of the FundUSOF is for the changes in percentage terms of its net asset value to reflect the changes in percentage terms of the price of light, sweet crude oil delivered to Cushing, Oklahoma, as measured by the changes in the price of the futures contract on light, sweet crude oil as traded on the New York Mercantile Exchange (the "NYMEX"“NYMEX”) that is the near month contract to expire, except when the near month contract is within two weeks of expiration, in which case the futures contract will be the next month contract to expire, less the Fund’sUSOF’s expenses. The FundUSOF will accomplish its objective through investments in futures contracts for light, sweet crude oil, and other types of crude oil, heating oil, gasoline, natural gas and other petroleum-based fuels that are traded on the NYMEX, ICE Futures andor other U.S. and foreign exchanges (collectively, “Oil Futures Contracts”) and other oil interestsrelated investments such as cash-settled options on Oil Futures Contracts, forward contracts for oil and over-the-counter transactions that are based on the price of oil.crude oil, heating oil, gasoline, natural gas and other petroleum-based fuels, Oil Futures Contracts and indices based on the foregoing (collectively, “Other Oil Interests”).

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Revenue Recognition

Commodity futures contracts, forward contracts, physical commodities, and related options are recorded on the trade date. All such transactions are recorded on the identified cost basis and marked to market daily. Unrealized gains or losses on open contracts are reflected in the condensed statement of financial condition and in the difference between the original contract amount and the market value (as determined by exchange settlement prices for futures contracts and related options and cash dealer prices at a predetermined time for forward contracts, physical commodities, and their related options) as of the last business day of the year or as of the last date of the condensed financial statements. Changes in the unrealized gains or losses between periods are reflected in the condensed statement of operations. The FundUSOF earns interest on its assets denominated in U.S. dollars on deposit with the futures commission merchant at the 90-day Treasury bill rate less 50 basis points.rate. In addition, the FundUSOF earns interest on funds held at the custodian at prevailing market rates earned on such investments.

Brokerage Commissions

Brokerage commissions on all open commodity futures contracts are accrued on a full-turn basis.
 
Income Taxes

The FundUSOF is not subject to federal income taxes; each partner reports his/herits allocable share of income, gain, loss deductions or credits on his/herits own income tax return.
 
Additions and Redemptions

Authorized purchasersPurchasers may purchase Creation Baskets consisting of 100,000 Units from the FundUSOF as of the beginning of each business day based upon the prior day’s net asset value. Authorized purchasersPurchasers may redeem Unitsunits from the FundUSOF only in blocks of 100,000 Unitsunits called “Redemption Baskets.”Baskets”. The amount of the redemption proceeds for a Redemption Basket will be equal to the net asset value of the Unitsunits in the Redemption Basket determined as of 4:00 p.m. New York time on the day the order to redeem the basket is properly received.

The FundUSOF receives or pays the proceeds from Unitsunits sold or redeemed one business day after the trade-date of the purchase or redemption. The amounts due from authorized purchasersAuthorized Purchasers are reflected in the Fund’sUSOF’s condensed statement of financial condition as receivable for Unitsunits sold, and amounts payable to authorized purchasersAuthorized Purchasers upon redemption are reflected as payable for Unitsunits redeemed.
 
Partnership Capital and Allocation of Partnership Income and Losses

Profit or loss is allocated among the partners of the FundUSOF in proportion to the number of Unitsunits each partner holds as of the close of each month. The General Partner may revise, alter or otherwise modify this method of allocation as described in the Limited PartnershipLP Agreement.

7

Calculation of Net Asset Value

The FundUSOF calculates its net asset value on each trading day by taking the current market value of its total assets, subtracting any liabilities and dividing the amount by the total number of Unitsunits issued and outstanding. The FundUSOF uses the closing price for the contracts on the relevant exchange on that day to determine the value of contracts held on such exchange.
8

 
Net Income (Loss) per Unit

Net income (loss) per Unitunit is the difference between the net asset value per Unitunit at the beginning of each period and at the end of each period. The weighted average number of Unitsunits outstanding was computed for purposes of disclosing net loss per weighted average Unit.unit. The weighted average Unitsunits are equal to the number of Unitsunits outstanding at the end of the period, adjusted proportionately for Unitsunits redeemed based on the amount of time the Unitsunits were outstanding during such period. There were no Unitsunits held by the General Partner at September 30, 2007.March 31, 2008.
 
Offering Costs

Offering costs incurred in connection with the registration of additional Unitsunits after the initial registration of Unitsunits are borne by the Fund.USOF. These costs include registration fees paid to regulatory agencies and all legal, accounting, printing and other expenses associated therewith. These costs will be accounted for as a deferred charge and thereafter amortized to expense over twelve months on a straight linestraight-line basis or a shorter period if warranted. 
 
Cash Equivalents

Cash and cash equivalents include money market portfolios and overnight time deposits with original maturity dates of three months or less.

Use of Estimates

The preparation of condensed financial statements in conformity with accounting principles generally accepted in the United States of America requires the Fund’sUSOF’s management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed financial statements, and the reported amounts of the revenue and expenses during the reporting period. Actual results could differ from those estimates and assumptions.

NOTE 5 - FINANCIAL INSTRUMENTS, OFF-BALANCE SHEET RISKS AND CONTINGENCIES

The FundUSOF engages in the speculative trading of Oil Futures ContractsU.S. futures contracts and options on Oil Futures ContractsU.S. futures contracts (collectively, “derivatives”). The FundUSOF is exposed to both market risk, which is the risk arising from changes in the market value of the contracts, and credit risk, which is the risk of failure by another party to perform according to the terms of a contract.

All of the contracts currently traded by the FundUSOF are exchange-traded. The risks associated with exchange-traded contracts are generally perceived to be less than those associated with over-the-counter transactions since, in over-the-counter transactions, the FundUSOF must rely solely on the credit of its respective individual counterparties. However, in the future, if the FundUSOF were to enter into non-exchange traded contracts, it would be subject to the credit risk associated with counterparty non-performance. The credit risk from counterparty non-performance associated with such instruments is the net unrealized gain, if any. The FundUSOF also has credit risk since the sole counterparty to all domestic and foreign futures contracts is the exchange on which the relevant contracts are traded. In addition, the FundUSOF bears the risk of financial failure by the clearing broker.
 
The purchase and sale of futures and options on futures contracts requiresrequire margin deposits with a futures commission merchant. Additional deposits may be necessary for any loss on contract value. The Commodity Exchange Act requires a futures commission merchant to segregate all customer transactions and assets from the futures commission merchant’s proprietary activities.

The Fund’sUSOF’s cash and other property, such as U.S. Treasury Bills, deposited with a futures commission merchant are considered commingled with all other customer funds subject to the futures commission merchant’s segregation requirements. In the event of a futures commission merchant’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 the total amount of cash and other property deposited. The insolvency of a futures commission merchant could result in the complete loss of USOFs assets posted with that futures commission merchant; however, the vast majority of USOF's assets are held in Treasuries, cash or cash equivalents with the USOFs custodian and would not be impacted by the insolvency of a futures commission merchant.
 
USOF invests its cash in money market funds that seek to maintain a stable net asset value. USOF is exposed to any risk of loss associated with an investment in these money market funds. As of September 30,March 31, 2008 and December 31, 2007, USOF had deposits in domestic and foreign financial institutions, including cash investments in money market funds, in the amount of $293,572,960.$630,349,360 and $441,146,799, respectively. This amount is subject to loss should these institutions cease operations.
9

For derivatives, risks arise from changes in the market value of the contracts. Theoretically, the FundUSOF is exposed to a market risk equal to the value of futures contracts purchased and unlimited liability on such contracts sold short. As both a buyer and a seller of options, the FundUSOF pays or receives a premium at the outset and then bears the risk of unfavorable changes in the price of the contract underlying the option.

The Fund’sUSOF’s policy is to continuously monitor its exposure to market and counterparty risk through the use of a variety of financial, position and credit exposure reporting controls and procedures. In addition, the FundUSOF has a policy of requiring review of the credit standing of each broker or counterparty with which it conducts business.

The financial instruments held by the FundUSOF are reported in its condensed statement of financial condition at market or fair value, or at carrying amounts that approximate fair value, because of their highly liquid nature and short-term maturity.

On March 17, 2006, the Fund received a letter from
11

Goldman, Sachs & Co. (“Goldman Sachs”) sent USOF a letter on March 17, 2006, providing USOF and the FundGeneral Partner notice under 35 U.S.C. Section 154(d) of two pending United States patent applications, Publication Nos. 2004/0225593A1 and 2006/0036533A1. The Fund is currently reviewing the Goldman Sachs published patent applications, and has engaged in discussions with Goldman Sachs regarding its pending applications and the Fund’s own pending patent application. The Fund is unable to determine the outcome of this matter at this time, due in part to the fact that the Goldman SachsBoth patent applications are pendinggenerally directed to a method and havesystem for creating and administering a publicly traded interest in a commodity pool. In particular, the abstract of each patent application defines a means for creating and administering a publicly traded interest in a commodity pool that includes the steps of forming a commodity pool having a first position in a futures contract and a corresponding second position in a margin investment, and issuing equity interests of the commodity pool to third party investors. Subsequently, two U.S. patents were issued; the first, patent number US7,283,978B2, was issued on October 16, 2007, and the second, patent number US7,319,984B2, was issued on January 15, 2008.

Preliminarily, USOF’s management is of the view that the structure and operations of USOF and its affiliated commodity pools do not been issued as U.S. Patents.infringe these patents. USOF is also in the process of reviewing prior art (prior structures and operations of similar investment vehicles) that may invalidate one or more of the claims in these patents. In addition, USOF has retained patent counsel to advise it on these matters and is in the process of obtaining their opinions regarding the non-infringement of each of these patents by USOF and/or the patents’ invalidity based on prior art. If the patents were alleged to apply to USOF’s structure and/or operations, and are found by a court to be valid and infringed, Goldman Sachs may be awarded significant monetary damages and/or injunctive relief.

Management's Discussion and Analysis of Financial Condition and Results of Operations





During the three month period from January 1, 2007 to September 30, 2007,ended March 31, 2008, the daily average total net assets of USOF were $815,003,993.$427,078,224. During the three month period from January 1,ended March 31, 2008, the total net assets of USOF did not exceed $1 billion on any day. The management fee paid by USOF during the period amounted to $530,931. Management fees as a percentage of total net assets averaged 0.50% over the course of this three month period. By comparison, for the three month period ended March 31, 2007, to September 30,the average daily total net assets of USOF were $970,772,068. During the three month period ended March 31, 2007, the total net assets of USOF did exceed $1 billion on a number of days. The management fee paid by USOF for this three month period amounted to $3,007,089,$1,144,115, which was calculated at the 0.50% rate for total net assets up to and including $1 billion and at the rate of 0.20% on totalaverage net assets over $1 billion, and accrued daily. Management expensesfees as a percentage of totalaverage net assets averaged 0.50% over the course of the nine month period. By comparison, for the three months ended September 30, 2006, the average daily total net assets of USOF was approximately $359,609,583. At no time during the quarter did the total net assets rise above the $1 billion level. The investment advisory fee paid by USOF amounted to $452,264. Management expenses as a percentage of total net assets averaged 0.50%0.48% over the course of this three month period.
USOF pays for all brokerage fees, taxes and other expenses, including certain tax reporting costs, licensing fees for the use of intellectual property, ongoing registration or other fees paid to the SEC, the Financial Industry Regulatory Authority ("FINRA"(“FINRA”) and any other regulatory agency in connection with subsequent offers and sales of its units subsequent to the initial offering and all legal, accounting, printing and other expenses associated therewith.  For the ninethree month period ended September 30, 2007,March 31, 2008, USOF incurred $384,058$105,629 in ongoing registration fees and other offering expenses. USOF is responsible for paying the fees and expenses, including directors'directors’ and officers'officers’ liability insurance, of the independent directors of the General Partner who are also audit committee members. USOF shares these fees with United States Natural Gas Fund, LP ("USNG")USNG, US12OF, USG and USHO based on the relative assets of each fund computed on a daily basis. These fees for calendar year 20072008 are estimated to be a total of $276,000$286,000 for bothall five funds. By comparison, for the three monthsmonth period ended September 30, 2006, the cost ofMarch 31, 2007, USOF incurred $369,059 in ongoing registration fees as well as director’s and officer’s liability insurance forother offering expenses. In addition, USOF agreed to pay the independent directors of the General Partner who are also audit committee members, were paid$184,000 to cover their expenses and pay for by the General Partner and were not an expense of USOF.their services for 2007.


Interest Income. USOF seeks to invest its assets such that it holds Oil Futures Contracts and Other Oil Interests in an amount equal to the total net assets of the portfolio. Typically, such investments do not require USOF to pay the full amount of the contract value at the time of purchase, but rather require USOF to post an amount as a margin deposit against the eventual settlement of the contract. As a result, USOF retains an amount that is approximately equal to its total net assets, which USOF invests in Treasuries, cash and/or cash equivalents. This includes both the amount on deposit with the Futures Commission Merchantfutures commission merchant as margin, as well as unrestricted cash held with USOF’s custodian bank. The Treasuries, cash and/or cash equivalents earn interest that accrues on a daily basis. For the three and nine monthsmonth period ended September 30, 2007,March 31, 2008, USOF earned $7,187,424 and $30,175,872, respectively,$2,895,300 in interest income on such cash holdings. Based on USOF’s average daily total net assets during this time period, this is equivalent to an annualized yield of 5.05% and 4.95%, respectively.2.73%. USOF did not purchase Treasuries during the three month period from January 1, 2007 through September 30, 2007ended March 31, 2008 and held all of its funds in cash and/or cash equivalents during this time period. By comparison, for the three monthsmonth period ended September 30, 2006,March 31, 2007, USOF earned $4,235,056$11,928,573 in interest income on cash holdings. Based on USOF’s average daily total net assets during this time period, which were smallerlarger than forUSOF’s assets during the same time period in 2007, the interest earned equaled2008, this is equivalent to an annualized yield of 4.7%4.98%.


For the three month period from July 1, 2007 through September 30, 2007,ended March 31, 2008, the actual total return of USOF as measured by changes in its NAV was 17.83%7.27%. This is based on an initial NAV of $53.18$75.82 on June 30,December 31, 2007 and an ending NAV as of September 30, 2007March 31, 2008 of $62.66.$81.33. During this time period, USOF made no distributions to its unitholders. However, if USOF’s daily changes in its NAV had instead exactly tracked the changes in the daily return of the Benchmark Oil Futures Contracts,Contract, USOF would have ended the thirdfirst quarter of 20072008 with an estimated NAV of $61.99,$81.01, for a total return over the relevant time period of 16.58%6.86%. The difference between the actual NAV total return of USOF of 17.83%7.27% and the expected total return based on the Benchmark Oil Futures ContractsContract of 16.58%6.86% was an error over the time period of +1.25%0.41%, which is to say that USOF’s actual total return exceeded the benchmark result by that percentage. Management believes that a portion of the difference between the actual return and the expected benchmark return can be attributed to the impact of the interest that USOF collects on its cash and cash equivalent holdings. In addition, during the ninethree month period ended September 30, 2007,March 31, 2008, USOF also collected fees from brokerage firms creating or redeeming baskets of units. This income also contributed to USOF’s actual return exceeding the benchmark results. However, if the total assets of USOF continue to increase, management believes that the impact on total returns of these fees from creations and redemptions will diminish as a percentage of the total return.


Second, USOF earns interest on its cash, cash equivalents and Treasury holdings. USOF is not required to distribute any portion of its income to its unitholders and did not make any distributiondistributions to unitholders induring the third quarter of 2007.three month period ended March 31, 2008. Interest payments, and any other income, were retained within the portfolio and added to USOF’s NAV. When this income exceeds the level of USOF’s expenses for its management fee, brokerage commissions and other expenses (including ongoing registration fees, licensing fees and the fees and expenses of the independent directors of the General Partner), USOF will realize a net yield that will tend to cause daily changes in the NAV of USOF to track slightly higher than daily changes in the Benchmark Oil Futures Contracts.Contract. During the third quarter of 2007,three month period ended March 31, 2008, USOF earned, on an annualized basis, approximately 5.05%2.73% on its cash holdings. It also incurred cash expenses on an annualized basis of 0.50% for management fees and approximately 0.14%0.22% in brokerage commission costs related to the purchase and sale of futures contracts, and 0.19%0.54% for other expenses. The foregoing fees and expenses resulted in a net yield on an annualized basis of approximately 4.21%1.46% and affected USOF’s ability to track its benchmark. If short-term interest rates rise above the current levels, the level of deviation created by the yield would increase. Conversely, if short-term interest rates were to decline, the amount of error created by the yield would decrease. If short-term yields drop to a level lower than the combined expenses of the management fee and the brokerage commissions, then the tracking error would become a negative number and would tend to cause the daily returns of the NAV to underperform the daily returns of the Benchmark Oil Futures Contracts.Contract.
















The General Partner attempts to manage the credit risk of USOF by following various trading limitations and policies. In particular, USOF generally posts margin and/or holds liquid assets that are approximately equal to the face amount of its obligations to counterparties under the Oil Futures Contracts and Other Oil Interests it holds. The General Partner has implemented procedures that include, but are not limited to, executing and clearing trades only with creditworthy parties and/or requiring the posting of collateral or margin by such parties for the benefit of USOF to limit its credit exposure. UBS Securities LLC, USOF'sUSOF’s commodity broker, or any other broker that may be retained by USOF in the future, when acting as USOF'sUSOF’s futures commission merchant in accepting orders to purchase or sell Oil Futures Contracts on United States exchanges, is required by U.S. Commodity Futures Trading Commission ("CFTC")CFTC regulations to separately account for and segregate as belonging to USOF, all assets of USOF relating to domestic Oil Futures Contracts trading. AThese futures commission merchant ismerchants are not allowed to commingle USOF'sUSOF’s assets with its other assets. In addition, the CFTC requires commodity brokers to hold in a secure account the USOF assets related to foreign Oil Futures ContractContracts trading. During the third quarter of 2007,three month period ended March 31, 2008, the only foreign exchange on which USOF made investments was the ICE Futures, which is a London based futures exchange. Those crude oil contracts are denominated in U.S. dollars.





Quantitative and Qualitative Disclosures About Market Risk


USOF may employ spreads or straddles in its trading to mitigate the differences in its investment portfolio and its goal of tracking the price of the Benchmark Oil Futures Contract. USOF would use a spread when it chooses to take simultaneous long and short positions in futures written on the same underlying asset, but with different delivery months. The effect of holding such combined positions is to adjust the sensitivity of USOF to changes in the price relationship between futures contracts which will expire sooner and those that will expire later. USOF would use such a spread if the General Partner felt that taking such long and short positions, when combined with the rest of its holdings, would more closely track the investment goals of USOF, or if the General Partner felt if it would lead to an overall lower cost of trading to achieve a given level of economic exposure to movements in oil prices. USOF would enter into a straddle when it chooses to take an option position consisting of a long (or short) position in both a call option and put option. The economic effect of holding certain combinations of put options and call options can be very similar to that of owning the underlying futures contracts. USOF would make use of such a straddle approach if, in the opinion of the General Partner, the resulting combination would more closely track the investment goals of USOF or if it would lead to an overall lower cost of trading to achieve a given level of economic exposure to movements in oil prices.
