ORGANIZATION AND BUSINESS |
ORGANIZATION AND BUSINESS | 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 are traded 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 and changes, over a ten-day period, into the NYMEX futures contract that is the next month to expire. The change from the near month contract to the next month contract occurs at the beginning of each month and will be approximately proportional, relative to total net assets, over each day of the ten-day roll period. 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 ten percent (10%) of the average daily percentage change in the price of the Benchmark Oil Futures Contract over the same period. As a result, investors should be aware that USO would meet its investment objective even if there are significant deviations between changes in its daily NAV and changes in the daily price of the Benchmark Oil Futures Contract provided that the average daily percentage change in USO’s NAV over 30 successive valuation days is within plus/minus ten percent (10%) of the average daily percentage change in the price of the Benchmark Oil Futures Contract over the same period. USO seeks to achieve its investment objective by investing primarily 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 to a lesser extent, in order to comply with regulatory requirements, risk mitigation measures (including those that may be taken by USO, USO’s futures commission merchants (“FCMs”), counterparties or other market participants), liquidity requirements, or in view of market conditions, 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, 2025, USO held 11,962 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. Following the significant market volatility that occurred in the Spring of 2020 and the market conditions, regulatory requirements and risk mitigation measures taken by USO and USO’s FCM that impacted USO as a result thereof, USO disclosed its parameters for making decisions regarding the permitted investments USO would hold, including the intended order of priority in selecting investments and the type of investments to be held in its portfolio. Beginning with the monthly roll in September 2023 and ending with the monthly roll in January 2024, USO transitioned its investment portfolio to primarily invest in the Benchmark Oil Futures Contract, consistent with USO’s investment strategy prior to the Spring of 2020. However, USO has had, and will continue to have, the ability to invest in Oil Futures Contracts beyond the Benchmark Oil Futures Contract and Other Oil-Related Investments, such as OTC swaps, and USO may make such investments if market conditions, (including but not limited to those allowing USO to obtain greater liquidity (i.e., liquidity requirements) or to execute transactions with more favorable pricing), regulatory requirements (including, but not limited to, exchange accountability levels and position limits imposed by NYMEX as well as statutory or regulatory limits), risk mitigation measures (including those that may be taken by USO, USO’s FCMs, counterparties or other market participants), liquidity requirements, or other factors require USO to do so in order to meet its investment objective. USO may invest in Oil Futures Contracts beyond the Benchmark Oil Futures Contract, and/or Other Oil-Related Investments, as a result of, or in response to, any of the foregoing factors. In addition, USO may need to hold significant portions of its portfolio in cash beyond what it has historically held for reasons including (but not limited to) the need to address changes in market conditions, regulatory requirements or risk mitigation measures or the need to satisfy potential margin requirements. 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, and may in the future impact, the total return on an investment in USO’s shares 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 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 commenced investment operations on April 10, 2006 and has a fiscal year ending on December 31. USCF is responsible for the management of USO. USCF is a member of the National Futures Association (the “NFA”) and became registered as a commodity pool operator (“CPO”) 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”), the United States Gasoline Fund, LP (“UGA”), the United States 12 Month Natural Gas Fund, LP (“UNL”) and the United States Brent Oil Fund, LP (“BNO”). 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”). 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 they place 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-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. USO has an unlimited number of shares available for issuance. On August 29, 2023, the SEC declared effective a registration statement filed by USO that registered an unlimited number of shares. As a result, USO has an unlimited number of shares that can be issued in the form of Creation Baskets. The accompanying unaudited 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 financial statements for the interim period.
