United States Oil Fund, LP

Notes to Condensed Financial Statements (Unaudited)

For the period ended September 30, 2021March 31, 2022

NOTE 1 — ORGANIZATION AND BUSINESS

The United States Oil Fund, LP (“USO”) was organized as a limited partnership under the laws of the state of Delaware on May 12, 2005. USO is a commodity pool that issues limited partnership interests (“shares”) that may be purchased and sold on the NYSE Arca, Inc. (the “NYSE Arca”). Prior to November 25, 2008, USO’s shares traded on the American Stock Exchange (the “AMEX”). USO will continue in perpetuity, unless terminated sooner upon the occurrence of one or more events as described in its Seventh Amended and Restated Agreement of Limited Partnership dated as of December 15, 2017 (the “LP Agreement”), which grants full management control to its general partner, United States Commodity Funds LLC (“USCF”). The investment objective of USO is for the daily changes in percentage terms of its shares’ per share net asset value (“NAV”) to reflect the daily changes in percentage terms of the spot price of light, sweet crude oil delivered to Cushing, Oklahoma, as measured by the daily changes in the price of the Benchmark Oil Futures Contract, plus interest earned on USO’s collateral holdings, less USO’s expenses. The Benchmark Oil Futures Contract is the futures contract for light, sweet crude oil as traded on the New York Mercantile Exchange (the “NYMEX”) that is the near month contract to expire, except when the near month contract is within two weeks of expiration, in which case it will be measured by the futures contract that is the next month contract to expire. Specifically, USO seeks to achieve its investment objective by investing so that the average daily percentage change in USO’s NAV for any period of 30 successive valuation days will be within plus/minus 10 percent (10)% of the average daily percentage change in the price of the Benchmark Oil Futures Contract over the same period. USO is currently unable to pursue its investment objective with the same high degree of success that it has in the past due to its limited ability to invest in the Benchmark Oil Futures Contract and certain other Oil Futures Contracts, as defined below, to the same extent it was able to before the market conditions that occurred in 2020, as described herein, and the resulting regulatory limitationsrequirements imposed on USO, occurred in Spring of 2020, and risk mitigation measures taken, including those taken by USO’s FCMs as a result, as described herein, arose.FCMs. As a result of such market conditions, the regulatory conditions that were and could again be imposed and the risk mitigation measures imposed by its FCMs,described below, there is still uncertainty as to whether USO will be able to achieve its investment objective within as narrow a percentage change difference in its NAV for any period of 30 successive valuation days and the average daily percentage change in the price of the Benchmark Oil Futures Contract as it typically had prior to the Spring of 2020 due to the foregoing factors.

Investors should be aware that USO’s investment objective is not for its NAV or market price of shares to equal, in dollar terms, the spot price of light, sweet crude oil or any particular futures contract based on light, sweet crude oil, nor is USO’s investment objective for the percentage change in its NAV to reflect the percentage change of the price of any particular futures contract as measured over a time period greater than one day. This is because natural market forces called contango and backwardation have impacted the total return on an investment in USO’s shares during the past year relative to a hypothetical direct investment in crude oil and, in the future, it is likely that the relationship between the market price of USO’s shares and changes in the spot prices of light, sweet crude oil will continue to be so impacted by contango and backwardation. While USO’s shares may be impacted by contango and backwardation, the potential costs associated with physically owning and storing crude oil, could be substantial. USCF believes that it is not practical to manage the portfolio to achieve the foregoing investment objective when investing in Oil Futures Contracts (as defined below) and Other Oil-Related Investments (as defined below). USO accomplishes its objective through investments in futures contracts for light, sweet crude oil and other types of crude oil, diesel-heating oil, gasoline, natural gas and other petroleum-based fuels that are traded on the NYMEX, ICE Futures or other U.S. and foreign exchanges (collectively, “Oil Futures Contracts”) and other oil-related investments such as cash-settled options on Oil Futures Contracts, forward contracts for oil, cleared swap contracts and over-the-counter (“OTC”) transactions that are based on the price of crude oil, diesel-heating oil, gasoline, natural gas and other petroleum-based fuels, Oil Futures Contracts and indices based on the foregoing (collectively, “Other Oil-Related Investments”). As of September 30, 2021,March 31, 2022, USO held 35,456 31,661 Oil Futures Contracts for light, sweet crude oil traded on the NYMEX and did not hold any Oil Futures Contracts for light, sweet crude oil traded on the ICE Futures Europe.

USO commenced investment operations on April 10, 2006 and has a fiscal year ending on December 31. USCF is a member of the National Futures Association (the “NFA”) and became registered as a commodity pool operator with the Commodity Futures Trading Commission (the “CFTC”) effective December 1, 2005 and a swaps firm on August 8, 2013.

USCF is also the general partner of the United States Natural Gas Fund, LP (“UNG”), the United States 12 Month Oil Fund, LP (“USL”) and the United States Gasoline Fund, LP (“UGA”), which listed their limited partnership shares on the AMEX under the ticker symbols “UNG” on April 18, 2007, “USL” on December 6, 2007 and “UGA” on February 26, 2008, respectively. As a result of the acquisition of the AMEX by NYSE Euronext, each of UNG’s, USL’s and UGA’s shares commenced trading on the NYSE Arca on November 25, 2008. USCF is also the general partner of the United States 12 Month Natural Gas Fund, LP (“UNL”) and the United States Brent Oil Fund, LP (“BNO”), which listed their limited partnership shares on the NYSE Arca under the ticker symbols “UNL” on November 18, 2009 and “BNO” on June 2, 2010, respectively.

USCF is also the sponsor of the United States Commodity Index Funds Trust (“USCIFT”), a Delaware statutory trust and each of its series: the United States Commodity Index Fund (“USCI”), and the United States Copper Index Fund (“CPER”) and the USCF Crescent Crypto Index Fund (“XBET”). USCI and CPER listed their shares on the NYSE Arca under the ticker symbols “USCI” on August 10, 2010 and “CPER” on November 15, 2011, respectively. A registration statement that had been previously filed for XBET was withdrawn on June 25, 2020.

USO, UNG, UGA, UNL, USL, BNO, USCI and CPER are referred to collectively herein as the “Related Public Funds.”

USO issues shares to certain authorized purchasers (“Authorized Participants”) by offering baskets consisting of 100,000 shares (“Creation Baskets”) through ALPS Distributors, Inc., as the marketing agent (the “Marketing Agent”). The purchase price for a Creation Basket is based upon the NAV of a share calculated shortly after the close of the core trading session on the NYSE Arca on the day the order to create the basket is properly received.

Authorized Participants pay USO a transaction fee of $1,000 for each order placed to create one or more Creation Baskets or to redeem one or more baskets (“Redemption Baskets”), consisting of 100,000 shares. Shares may be purchased or sold on a nationally recognized securities exchange in smaller increments than a Creation Basket or Redemption Basket. Shares purchased or sold on a nationally recognized securities exchange are not purchased or sold at the per share NAV of USO but rather at market prices quoted on such exchange.

On April 28, 2020, after the close of trading on the NYSE Arca, USO effected a 1-for-81-for-8 reverse share split and post-split shares of USO began trading on April 29, 2020. As a result of the reverse share split, every eight pre-split shares of USO were automatically exchanged for one post-split share. Immediately prior to the reverse split, there were 1,482,900,000 shares of USO issued and outstanding, representing a per share NAV of $2.04. Immediately after the effect of the reverse share split, the number of issued and outstanding shares of USO decreased to 185,362,500, not accounting for fractional shares, and the per share NAV increased to $16.35. In connection with the reverse share split, the CUSIP number for USO’s shares changed to 91232N207. USO’s ticker symbol, “USO,” remains the same. The accompanying financial statements have been adjusted to reflect the effect of the reverse share split on a retroactive basis.

In April 2006, USO initially registered 17,000,000 shares on Form S-1 with the U.S. Securities and Exchange Commission (the “SEC”). On April 10, 2006, USO listed its shares on the AMEX under the ticker symbol “USO” and switched to trading on the NYSE Arca under the same ticker symbol on November 25, 2008. On that day, USO established its initial per share NAV by setting the price at $67.39 and issued 200,000 shares in exchange for $13,479,000. USO also commenced investment operations on April 10, 2006, by purchasing Oil Futures Contracts traded on the NYMEX based on light, sweet crude oil. As of September 30, 2021,March 31, 2022, USO had registered a total of 5,627,000,000 shares.

The accompanying unaudited condensed financial statements have been prepared in accordance with Rule 10-01 of Regulation S-X promulgated by the SEC and, therefore, do not include all information and footnote disclosure required under generally accepted accounting principles in the United States of America (“U.S. GAAP”). The financial information included herein is unaudited; however, such financial information reflects all adjustments, consisting only of normal recurring adjustments, which are, in the opinion of USCF, necessary for the fair presentation of the condensed financial statements for the interim period.

​

NOTE 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The condensed financial statements have been prepared in conformity with U.S. GAAP as detailed in the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification. USO is an investment company for accounting purposes and follows the accounting and reporting guidance in FASB Topic 946.

Table of Contents

Revenue Recognition

Commodity futures contracts, swap and 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 statements of financial condition and represent 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 swap and 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 statements of operations. USO earns income on funds held at the custodian or futures commission merchants (“FCMs”) 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

USO is not subject to federal income taxes; each partner reports his/her allocable share of income, gain, loss deductions or credits on his/her own income tax return.

In accordance with U.S. GAAP, USO is required to determine whether a tax position is more likely than not to be sustained upon examination by the applicable taxing authority, including resolution of any tax related appeals or litigation processes, based on the technical merits of the position. USO files an income tax return in the U.S. federal jurisdiction and may file income tax returns in various U.S. states. USO is not subject to income tax return examinations by major taxing authorities for years before 2018. The tax benefit recognized is measured as the largest amount of benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement. De-recognition of a tax benefit previously recognized results in USO recording a tax liability that reduces net assets. However, USO’s conclusions regarding this policy may be subject to review and adjustment at a later date based on factors including, but not limited to, on-going analysis of and changes to tax laws, regulations and interpretations thereof. USO recognizes interest accrued related to unrecognized tax benefits and penalties related to unrecognized tax benefits in income tax fees payable, if assessed. NaN interest expense or penalties have been recognized as of and for the period ended September 30, 2021.March 31, 2022.

Creations and Redemptions

Authorized Participants may purchase Creation Baskets or redeem Redemption Baskets only in blocks of 100,000 shares at a price equal to the NAV of the shares calculated shortly after the close of the core trading session on the NYSE Arca on the day the order is placed.

USO receives or pays the proceeds from shares sold or redeemed within two business days after the trade date of the purchase or redemption. The amounts due from Authorized Participants are reflected in USO’s condensed statements of financial condition as receivable for shares sold and amounts payable to Authorized Participants upon redemption are reflected as payable for shares redeemed.

Authorized Participants pay USO a $1,000 transaction fee for each order placed to create one or more Creation Baskets or to redeem one or more Redemption Baskets.

Partnership Capital and Allocation of Partnership Income and Losses

Profit or loss shall be allocated among the partners of USO in proportion to the number of shares each partner holds as of the close of each month. USCF may revise, alter or otherwise modify this method of allocation as described in the LP Agreement.

Calculation of Per Share NAV

USO’s per share NAV is calculated on each NYSE Arca trading day by taking the current market value of its total assets, subtracting any liabilities and dividing that amount by the total number of shares outstanding. USO uses the closing price for the contracts on the relevant exchange on that day to determine the value of contracts held on such exchange.

Table of Contents

Net Income (Loss) Per Share

Net income (loss) per share is the difference between the per share NAV at the beginning of each period and at the end of each period. The weighted average number of shares outstanding was computed for purposes of disclosing net income (loss) per weighted average share. The weighted average shares are equal to the number of shares outstanding at the end of the period, adjusted proportionately for shares added and redeemed based on the amount of time the shares were outstanding during such period. There were 0 shares held by USCF at September 30, 2021.March 31, 2022.

Offering Costs

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

Cash Equivalents

Cash equivalents include money market funds and overnight deposits or time deposits with original maturity dates of six months or less.

Reclassification

Certain amounts in the accompanying condensed financial statements were reclassified to conform to the current presentation.

Use of Estimates

The preparation of condensed financial statements in conformity with U.S. GAAP requires USCF 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 may differ from those estimates and assumptions.
