**REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM**

To the Partners of

United States Oil Fund, LP

**Opinions on the Financial Statements and Internal Control over Financial Reporting**

We have audited the accompanying statements of financial condition of United States Oil Fund, LP (the "Fund") as of December 31, 2022 and 2021, including the schedule of investments as of December 31, 2022 and 2021, and the related statements of operations, changes in partners' capital and cash flows for each of the years in the three-year period ended December 31, 2022, and the related notes (collectively referred to as the "financial statements"). We also have audited the Fund's internal control over financial reporting as of December 31, 2022, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO").

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of United States Oil Fund, LP as of December 31, 2022 and 2021, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2022, in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion, the Fund maintained, in all material respects, effective internal control over financial reporting as of December 31, 2022 based on criteria established in Internal Control — Integrated Framework (2013) issued by COSO.

**Basis for Opinion** 

The Fund's management is responsible for these financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management's Annual Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Fund's financial statements and an opinion on the Fund's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the financial statements included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

![](i23129002.jpg)

**Definition and Limitations of Internal Control over Financial Reporting**

A Fund's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A Fund's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Fund; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the Fund are being made only in accordance with authorizations of management and directors of the Fund; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the Fund's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

**Critical Audit Matters**

Critical audit matters are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. We determined that there are no critical audit matters.

We have served as the Fund's auditor since 2005.

**United States Oil Fund, LP**

**Notes to Financial Statements<br> For the years ended December 31, 2022, 2021 and 2020**

**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 ten 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 requirements imposed on USO, and risk mitigation measures taken, including those taken by USO's FCMs. As a result of such market conditions, the regulatory conditions that were and could again be imposed and the risk mitigation measures 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 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 December 31, 2022, USO held 21,034 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"). 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.

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-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 December 31, 2022, USO had registered a total of 5,627,000,000 shares.

**NOTE 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES**

**Basis of Presentation**

The 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.

**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 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 financial statements. Changes in the unrealized gains or losses between periods are reflected in the 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 2019. 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. No interest expense or penalties have been recognized as of and for the year ended December 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 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.

**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 no shares held by USCF at December 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 financial statements were reclassified to conform to the current presentation.

**Use of Estimates**

The preparation of 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 financial statements, and the reported amounts of the revenue and expenses during the reporting period. Actual results may differ from those estimates and assumptions.

**NOTE 3 — FEES PAID BY THE FUND AND RELATED PARTY TRANSACTIONS**

**USCF Management Fee**

Under the LP Agreement, USCF is responsible for investing the assets of USO in accordance with the objectives and policies of USO. In addition, USCF has arranged for one or more third parties to provide administrative, custody, accounting, transfer agency and other necessary services to USO. For these services, USO is contractually obligated to pay USCF a fee, which is paid monthly, equal to 0.45% per annum of average daily total net assets.

**Ongoing Registration Fees and Other Offering Expenses**

USO pays all costs and expenses associated with the ongoing registration of its shares subsequent to the initial offering. These costs include registration or other fees paid to regulatory agencies in connection with the offer and sale of shares, and all legal, accounting, printing and other expenses associated with such offer and sale. For the year ended December 31, 2022, USO did not incur in registration fees and other offering expenses. For the years ended December 31, 2022, 2021 and 2020, USO incurred $0, $1,260,041 and $3,203,939 respectively, in registration fees and other offering expenses.

**Independent Directors' and Officers' Expenses**

USO is responsible for paying its portion of the directors' and officers' liability insurance for USO and the other Related Public Funds and the fees and expenses of the independent directors who also serve as audit committee members of USO and the other Related Public Funds. USO shares the fees and expenses on a pro rata basis with each other Related Public Fund, as described above, based on the relative assets of each Related Public Fund computed on a daily basis. These fees and expenses for the year ending December 31, 2022 totaled $828,823 for USO and, in the aggregate for USO and the other Related Public Funds, approximately $1,258,000. For the year ending December 31, 2021 these fees and expenses were $745,448 for USO and, in the aggregate for USO and the Related Public Funds, $1,081,963. For the year ended December 31, 2020, these fees and expenses were $585,896 for USO and the Related Public Funds. USO's portion of such fees and expenses for the year ended December 31, 2020 was $391,372.

**Licensing Fees**

As discussed in Note 4 below, USO entered into a licensing agreement with the NYMEX on April 10, 2006, as amended on October 20, 2011. Pursuant to the agreement, USO and the other Related Public Funds, other than BNO, USCI and CPER, pay a licensing fee that is equal to 0.015% on all net assets. During the years ended December 31, 2022, 2021 and 2020, USO incurred $384,747, $446,110 and $512,944, respectively under this arrangement.

**Investor Tax Reporting Cost**

The fees and expenses associated with USO's audit expenses and tax accounting and reporting requirements are paid by USO. These costs were estimated to be $1,779,300 for the year ending December 31, 2022. For the years ending December 31, 2021, and 2020 USO's investor reporting costs totaled $6,671,000 and $2,694,975 respectively. Tax reporting costs fluctuate between years due to the number of shareholders during any given year.

**Other Expenses and Fees**

In addition to the fees described above, USO pays all brokerage fees and other expenses in connection with the operation of USO, excluding costs and expenses paid by USCF as outlined in *Note 4 – Contracts and Agreements* below.

**NOTE 4 — CONTRACTS AND AGREEMENTS**

**Marketing Agent Agreement**

USO is party to a marketing agent agreement, dated as of March 13, 2006, as amended from time to time, with the Marketing Agent and USCF, whereby the Marketing Agent provides certain marketing services for USO as outlined in the agreement. The fees of the Marketing Agent, which are borne by USCF, include a marketing fee of $425,000 per annum plus the following incentive fee: 0.00% on USO's assets from $0 – $500 million; 0.04% on USO's assets from $500 million – $4 billion and 0.03% on USO's assets in excess of $4 billion. The agreement with the Marketing Agent has been amended and, commencing October 1, 2022, the fee of the Marketing Agent, which is calculated daily and payable monthly by USCF, is equal to 0.025% of USO's total net assets. In no event may the aggregate compensation paid to the Marketing Agent and any affiliate of USCF for distribution-related services exceed 10% of the gross proceeds of USO's offering.

The above fee does not include website construction and development, which are also borne by USCF.

**Custody, Transfer Agency and Fund Administration and Accounting Services Agreements**

USCF engaged The Bank of New York Mellon, a New York corporation authorized to conduct a banking business ("BNY Mellon"), to provide USO and each of the other Related Public Funds with certain custodial, administrative and accounting, and transfer agency services, pursuant to the following agreements with BNY Mellon dated as of March 20, 2020 (together, the "BNY Mellon Agreements"), which were effective as of April 1, 2020: (i) a Custody Agreement; (ii) a Fund Administration and Accounting Agreement; and (iii) a Transfer Agency and Service Agreement. USCF pays the fees of BNY Mellon for its services under the BNY Mellon Agreements and such fees are determined by the parties from time to time.

**Brokerage and Futures Commission Merchant Agreements**

USO entered into a brokerage agreement with RBC Capital Markets LLC ("RBC") to serve as USO's FCM effective October 10, 2013. USO has engaged each of RCG Division of Marex Spectron ("RCG"), E D & F Man Capital Markets Inc. ("MCM") and Macquarie Futures USA LLC ("MFUSA") to serve as additional FCMs to USO effective on May 28, 2020, June 5, 2020, and December 3, 2020, respectively. The agreements with USO's FCMs require the FCMs to provide services to USO in connection with the purchase and sale of Oil Futures Contracts and Other Oil-Related Investments that may be purchased and sold by or through the applicable FCM for USO's account. In accordance with the FCM agreements, USO pays each FCM commissions of approximately $7 to $8 per round-turn trade, including applicable exchange, clearing and NFA fees for Oil Futures Contracts and options on Oil Futures Contracts. Such fees include those incurred when purchasing Oil Futures Contracts and options on Oil Futures Contracts when USO issues shares as a result of a Creation Basket, as well as fees incurred when selling Oil Futures Contracts and options on Oil Futures Contracts when USO redeems shares as a result of a Redemption Basket. Such fees are also incurred when Oil Futures Contracts and options on Oil Futures Contracts are purchased or redeemed for the purpose of rebalancing the portfolio. USO also incurs commissions to brokers for the purchase and sale of Oil Futures Contracts, Other Oil-Related Investments or short-term obligations of the United States of two years or less ("Treasuries").

---

The decrease in total commissions accrued to brokers for the year ended December 31, 2022, compared to the year ended December 31, 2021, was due primarily to a lower number of crude oil futures contracts being held and traded.

**Swap Dealer Agreements**

USO entered into ISDA 2002 Master Agreements with each of Macquarie Bank Limited the ("Macquarie ISDA") and Société Générale ("Société Générale ISDA") on November 30, 2021 and June 13, 2022, respectively, pursuant to which each of Macquarie Bank Limited and Société Générale has agreed to serve as an over-the-counter ("OTC") swap counterparty for USO. The Macquarie ISDA and the Société Générale ISDA each provide USO with the ability to invest in OTC swaps in furtherance of USO's investment objective by providing it with investment flexibility in light of market conditions, liquidity, regulatory requirements, and risk diversification. USO may enter into OTC swap transactions under each of the Macquarie ISDA and Société Générale ISDA in light of the foregoing. Any OTC swap transactions of USO that are outstanding under the Macquarie ISDA and the Société Générale ISDA, along with USO's other holdings, will be published on USO's webpage, www.uscfinvestments.com. In accordance with each of the swap agreements described above, USO pays each swap dealer a flat fee in a range between 0.20% and 0.30% on the daily notional value of each OTC swap transaction.

**NYMEX Licensing Agreement**

USO and the NYMEX entered into a licensing agreement on April 10, 2006, as amended on October 20, 2011, whereby USO was granted a non-exclusive license to use certain of the NYMEX's settlement prices and service marks. Under the licensing agreement, USO and the other Related Public Funds, other than BNO, USCI, and CPER, pay the NYMEX an asset-based fee for the license, the terms of which are described in Note 3. USO expressly disclaims any association with the NYMEX or endorsement of USO by the NYMEX and acknowledges that "NYMEX" and "New York Mercantile Exchange" are registered trademarks of the NYMEX.

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

USO may engage in the trading of futures contracts, options on futures contracts, cleared swaps and OTC swaps (collectively, "derivatives"). USO 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.

USO may enter into futures contracts, options on futures contracts, cleared swaps, and OTC-swaps to gain exposure to changes in the value of an underlying commodity. A futures contract obligates the seller to deliver (and the purchaser to accept) the future delivery of a specified quantity and type of a commodity at a specified time and place. Some futures contracts may call for physical delivery of the asset, while others are settled in cash. The contractual obligations of a buyer or seller may generally be satisfied by taking or making physical delivery of the underlying commodity or by making an offsetting sale or purchase of an identical futures contract on the same or linked exchange before the designated date of delivery. Cleared swaps are agreements that are eligible to be cleared by a clearinghouse, e.g., ICE Clear Europe, and provide the efficiencies and benefits that centralized clearing on an exchange offers to traders of futures contracts, including credit risk intermediation and the ability to offset positions initiated with different counterparties. OTC swaps are entered into between two parties in private contracts. In an OTC swap, each party bears credit risk to the other party, i.e., the risk that the other party may not be able to perform its obligations under the OTC swap.

The purchase and sale of futures contracts, options on futures contracts and cleared swaps require margin deposits with an FCM. Additional deposits may be necessary for any loss on contract value. The Commodity Exchange Act requires FCMs to segregate all customer transactions and assets from the FCM's proprietary transactions and assets. To reduce the credit risk that arises in connection with OTC swaps, USO will generally enter into an agreement with each counterparty based on the Master Agreement published by the International Swaps and Derivatives Association, Inc., which provides for the netting of its overall exposure to its counterparty. The Master Agreement is negotiated as between the parties and would address, among other things, the exchange of margin between the parties.

Futures contracts, options on futures contracts and cleared swaps involve, to varying degrees, elements of market risk (specifically commodity price risk) and exposure to loss in excess of the amount of variation margin. The face or contract amounts reflect the extent of the total exposure USO has in the particular classes of instruments. Additional risks associated with the use of futures contracts are an imperfect correlation between movements in the price of the futures contracts and the market value of the underlying securities and the possibility of an illiquid market for a futures contract. Buying and selling options on futures contracts exposes investors to the risks of purchasing or selling futures contracts.

As to OTC swaps, valuing OTC derivatives is less certain than valuing actively traded financial instruments such as exchange-traded futures contracts and securities or cleared swaps, because the price and terms on which such OTC derivatives are entered into or can be terminated are individually negotiated, and those prices and terms may not reflect the best price or terms available from other sources. In addition, while market makers and dealers generally quote indicative prices or terms for entering into or terminating OTC contracts, they typically are not contractually obligated to do so, particularly if they are not a party to the transaction. As a result, it may be difficult to obtain an independent value for an outstanding OTC derivatives transaction.

Significant market volatility has recently occurred in the crude oil markets and the crude oil futures markets. Such volatility is attributable in part to the COVID-19 pandemic, related supply chain disruptions, war, including the war in Ukraine, and continuing disputes among oil-producing countries. These factors could cause continuing or increased volatility in the future, which may affect the value, pricing and liquidity of some investments or other assets, including those held by or invested in by USO and the impact of which could limit USO's ability to have a substantial portion of its assets invested in the Futures Contracts and/or Other Oil-Related Investments.

All of the futures contracts held by USO through December 31, 2022 were exchange-traded. The risks associated with exchange-traded contracts are generally perceived to be less than those associated with OTC swaps since, in OTC swaps, a party must rely solely on the credit of its respective individual counterparties. USO entered OTC swaps during the period ended March 31, 2022. These OTC swaps are 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, on the transaction. USO also has credit risk to the sole counterparty to all domestic and foreign futures contracts, the clearinghouse for the exchange on which the relevant contracts are traded. In addition, USO bears the risk of financial failure by the clearing broker.

USO's cash and other property, such as Treasuries, deposited with its FCMs are considered commingled with all other customer funds, subject to such FCM's segregation requirements. In the event of an FCM'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 of cash and other property deposited. The insolvency of an FCM could result in the complete loss of USO's assets posted with that FCM; however, the majority of USO's assets are held in investments in Treasuries, cash and/or cash equivalents with USO's custodian and would not be impacted by the insolvency of an FCM. The failure or insolvency of USO's custodian, however, could result in a substantial loss of USO's assets.

USCF invests a portion of USO's cash in money market funds that seek to maintain a stable per share NAV. USO is exposed to any risk of loss associated with an investment in such money market funds. As of December 31, 2022 and December 31, 2021, USO held investments in money market funds in the amounts of $856,400,000 and $1,544,534,000, respectively. USO also holds cash deposits with its custodian. As of December 31, 2022 and December 31, 2021, USO held cash deposits and investments in Treasuries in the amounts of $1,097,496,501 and $719,884,396 respectively, with the custodian and FCMs. Some or all of these amounts may be subject to loss should USO's custodian and/or FCMs cease operations.

For derivatives, risks arise from changes in the market value of the contracts. Theoretically, USO is exposed to market risk equal to the value of futures contracts purchased and unlimited liability on such contracts sold short or that the value of the futures contract could fall below zero. As both a buyer and a seller of options, USO 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.

USO'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, USO 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 USO are reported in its statements 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.

*Optimum Strategies Action*

On April 6, 2022, USO and USCF were named as defendants in an action filed by Optimum Strategies Fund I, LP, a purported investor in call option contracts on USO (the "Optimum Strategies Action"). The action is pending in the U.S. District Court for the District of Connecticut at Civil Action No. 3:22-cv-00511.

The Optimum Strategies Action asserts claims under the Securities Exchange Act of 1934, as amended (the "1934 Act"), Rule 10b-5 thereunder, and the Connecticut Uniform Securities Act. It purports to challenge statements in registration statements that became effective in February 2020, March 2020, and on April 20, 2020, as well as public statements between February 2020 and May 2020, in connection with certain extraordinary market conditions and the attendant risks that caused the demand for oil to fall precipitously, including the COVID-19 global pandemic and the Saudi Arabia-Russia oil price war. The complaint seeks damages, interest, costs, attorney's fees, and equitable relief.

USCF and USO intend to vigorously contest such claims and have moved for their dismissal.

*Settlement of SEC and CFTC Investigations*

On November 8, 2021, USCF and USO announced a resolution with each of the SEC and the CFTC relating to matters set forth in certain Wells Notices issued by the staffs of each of the SEC and CFTC as more fully described below.

On August 17, 2020, USCF, USO, and John Love received a "Wells Notice" from the staff of the SEC (the "SEC Wells Notice"). The SEC Wells Notice stated that the SEC staff made a preliminary determination to recommend that the SEC file an enforcement action against USCF, USO, and Mr. Love alleging violations of Sections 17(a)(1) and 17(a)(3) of the Securities Act of 1933, as amended (the "1933 Act"), and Section 10(b) of the 1934 Act, and Rule 10b-5 thereunder.

Subsequently, on August 19, 2020, USCF, USO, and Mr. Love received a Wells Notice from the staff of the CFTC (the "CFTC Wells Notice"). The CFTC Wells Notice stated that the CFTC staff made a preliminary determination to recommend that the CFTC file an enforcement action against USCF, USO, and Mr. Love alleging violations of Sections 4o(1)(A) and (B) and 6(c)(1) of the Commodity Exchange Act of 1936, as amended (the "CEA"), 7 U.S.C. §§ 6o(1)(A) and (B) and 9(1) (2018), and CFTC Regulations 4.26, 4.41, and 180.1(a), 17 C.F.R. §§ 4.26, 4.41, 180.1(a) (2019).

On November 8, 2021, acting pursuant to an offer of settlement submitted by USCF and USO, the SEC issued an order instituting cease-and-desist proceedings, making findings, and imposing a cease-and-desist order pursuant to Section 8A of the 1933 Act, directing USCF and USO to cease and desist from committing or causing any violations of Section 17(a)(3) of the 1933 Act, 15 U.S.C. § 77q(a)(3) (the "SEC Order"). In the SEC Order, the SEC made findings that, from April 24, 2020 to May 21, 2020, USCF and USO violated Section 17(a)(3) of 1933 Act, which provides that it is "unlawful for any person in the offer or sale of any securities to engage in any transaction, practice, or course of business which operates or would operate as a fraud or deceit upon the purchaser." USCF and USO consented to entry of the SEC Order without admitting or denying the findings contained therein, except as to jurisdiction.

Separately, on November 8, 2021, acting pursuant to an offer of settlement submitted by USCF, the CFTC issued an order instituting cease-and-desist proceedings, making findings, and imposing a cease-and-desist order pursuant to Section 6(c) and (d) of the CEA, directing USCF to cease and desist from committing or causing any violations of Section 4o(1)(B) of the CEA, 7 U.S.C. § 6o(1) (B), and CFTC Regulation 4.41(a)(2), 17 C.F.R. § 4.41(a)(2) (the "CFTC Order"). In the CFTC Order, the CFTC made findings that, from on or about April 22, 2020 to June 12, 2020, USCF violated Section 4o(1)(B) of the CEA and CFTC Regulation 4.41(a)(2), which make it unlawful for any commodity pool operator ("CPO") to engage in "any transaction, practice, or course of business which operates as a fraud or deceit upon any client or participant or prospective client or participant" and prohibit a CPO from advertising in a manner which "operates as a fraud or deceit upon any client or participant or prospective client or participant," respectively. USCF consented to entry of the CFTC Order without admitting or denying the findings contained therein, except as to jurisdiction.

Pursuant to the SEC Order and the CFTC Order, in addition to the command to cease and desist from committing or causing any violations of Section 17(a)(3) of the 1933 Act, Section 4o(1)(B) of the CEA, and CFTC Regulation 4.14(a)(2), civil monetary penalties totaling two million five hundred thousand dollars ($2,500,000) in the aggregate were required to be paid to the SEC and CFTC, of which one million two hundred fifty thousand dollars ($1,250,000) was paid by USCF to each of the SEC and the CFTC, respectively, pursuant to the offsets permitted under the orders.

*In re: United States Oil Fund, LP Securities Litigation*

On June 19, 2020, USCF, USO, John P. Love, and Stuart P. Crumbaugh were named as defendants in a putative class action filed by purported shareholder Robert Lucas (the "Lucas Class Action"). The Court thereafter consolidated the Lucas Class Action with two related putative class actions filed on July 31, 2020 and August 13, 2020, and appointed a lead plaintiff. The consolidated class action is pending in the U.S. District Court for the Southern District of New York under the caption *In re: United States Oil Fund, LP Securities Litigation*, Civil Action No. 1:20-cv-04740.

On November 30, 2020, the lead plaintiff filed an amended complaint (the "Amended Lucas Class Complaint"). The Amended Lucas Class Complaint asserts claims under the 1933 Act, the Exchange Act, and Rule 10b-5. The Amended Lucas Class Complaint challenges statements in registration statements that became effective on February 25, 2020 and March 23, 2020 as well as subsequent public statements through April 2020 concerning certain extraordinary market conditions and the attendant risks that caused the demand for oil to fall precipitously, including the COVID-19 global pandemic and the Saudi Arabia-Russia oil price war. The Amended Lucas Class Complaint purports to have been brought by an investor in USO on behalf of a class of similarly-situated shareholders who purchased USO securities between February 25, 2020 and April 28, 2020 and pursuant to the challenged registration statements. The Amended Lucas Class Complaint seeks to certify a class and to award the class compensatory damages at an amount to be determined at trial as well as costs and attorney's fees. The Amended Lucas Class Complaint named as defendants USCF, USO, John P. Love, Stuart P. Crumbaugh, Nicholas D. Gerber, Andrew F Ngim, Robert L. Nguyen, Peter M. Robinson, Gordon L. Ellis, and Malcolm R. Fobes III, as well as the marketing agent, ALPS Distributors, Inc., and the Authorized Participants: ABN Amro, BNP Paribas Securities Corporation, Citadel Securities LLC, Citigroup Global Markets, Inc., Credit Suisse Securities USA LLC, Deutsche Bank Securities Inc., Goldman Sachs & Company, J.P. Morgan Securities Inc., Merrill Lynch Professional Clearing Corporation, Morgan Stanley & Company Inc., Nomura Securities International Inc., RBC Capital Markets LLC, SG Americas Securities LLC, UBS Securities LLC, and Virtu Financial BD LLC.

The lead plaintiff has filed a notice of voluntary dismissal of its claims against BNP Paribas Securities Corporation, Citadel Securities LLC, Citigroup Global Markets Inc., Credit Suisse Securities USA LLC, Deutsche Bank Securities Inc., Morgan Stanley & Company, Inc., Nomura Securities International, Inc., RBC Capital Markets, LLC, SG Americas Securities LLC, and UBS Securities LLC.

USCF, USO, and the individual defendants in *In re: United States Oil Fund, LP Securities Litigation* intend to vigorously contest such claims and have moved for their dismissal.

*Wang Class Action*

On July 10, 2020, purported shareholder Momo Wang filed a putative class action complaint, individually and on behalf of others similarly situated, against defendants USO, USCF, John P. Love, Stuart P. Crumbaugh, Nicholas D. Gerber, Andrew F Ngim, Robert L. Nguyen, Peter M. Robinson, Gordon L. Ellis, Malcolm R. Fobes, III, ABN Amro, BNP Paribas Securities Corp., Citadel Securities LLC, Citigroup Global Markets Inc., Credit Suisse Securities USA LLC, Deutsche Bank Securities Inc., Goldman Sachs & Company, JP Morgan Securities Inc., Merrill Lynch Professional Clearing Corp., Morgan Stanley & Company Inc., Nomura Securities International Inc., RBC Capital Markets LLC, SG Americas Securities LLC, UBS Securities LLC, and Virtu Financial BD LLC, in the U.S. District Court for the Northern District of California as Civil Action No. 3:20-cv-4596 (the "Wang Class Action").

The Wang Class Action asserted federal securities claims under the 1933 Act, challenging disclosures in a March 19, 2020 registration statement. It alleged that the defendants failed to disclose to investors in USO certain extraordinary market conditions and the attendant risks that caused the demand for oil to fall precipitously, including the COVID-19 global pandemic and the Saudi Arabia-Russia oil price war. The Wang Class Action was voluntarily dismissed on August 4, 2020.

*Mehan Action*

On August 10, 2020, purported shareholder Darshan Mehan filed a derivative action on behalf of nominal defendant USO, against defendants USCF, John P. Love, Stuart P. Crumbaugh, Nicholas D. Gerber, Andrew F Ngim, Robert L. Nguyen, Peter M. Robinson, Gordon L. Ellis, and Malcolm R. Fobes, III (the "Mehan Action"). The action is pending in the Superior Court of the State of California for the County of Alameda as Case No. RG20070732.

The Mehan Action alleges that the defendants breached their fiduciary duties to USO and failed to act in good faith in connection with a March 19, 2020 registration statement and offering and disclosures regarding certain extraordinary market conditions that caused demand for oil to fall precipitously, including the COVID-19 global pandemic and the Saudi Arabia-Russia oil price war. The complaint seeks, on behalf of USO, compensatory damages, restitution, equitable relief, attorney's fees, and costs. All proceedings in the Mehan Action are stayed pending disposition of the motion(s) to dismiss in *In re: United States Oil Fund, LP Securities Litigation*.

USCF, USO, and the other defendants intend to vigorously contest such claims.

*In re United States Oil Fund, LP Derivative Litigation*

On August 27, 2020, purported shareholders Michael Cantrell and AML Pharm. Inc. DBA Golden International filed two separate derivative actions on behalf of nominal defendant USO, against defendants USCF, John P. Love, Stuart P. Crumbaugh, Andrew F Ngim, Gordon L. Ellis, Malcolm R. Fobes, III, Nicholas D. Gerber, Robert L. Nguyen, and Peter M. Robinson in the U.S. District Court for the Southern District of New York at Civil Action No. 1:20-cv-06974 (the "Cantrell Action") and Civil Action No. 1:20-cv-06981 (the "AML Action"), respectively.

The complaints in the Cantrell and AML Actions are nearly identical. They each allege violations of Sections 10(b), 20(a), and 21D of the Exchange Act, Rule 10b-5 thereunder, and common law claims of breach of fiduciary duties, unjust enrichment, abuse of control, gross mismanagement, and waste of corporate assets. These allegations stem from USO's disclosures and defendants' alleged actions in light of the extraordinary market conditions in 2020 that caused demand for oil to fall precipitously, including the COVID-19 global pandemic and the Saudi Arabia-Russia oil price war. The complaints seek, on behalf of USO, compensatory damages, restitution, equitable relief, attorney's fees, and costs. The plaintiffs in the Cantrell and AML Actions have marked their actions as related to the Lucas Class Action.

The Court consolidated the Cantrell and AML Actions under the caption *In re United States Oil Fund, LP Derivative Litigation*, Civil Action No. 1:20-cv-06974 and appointed co-lead counsel. All proceedings in *In re United States Oil Fund, LP Derivative Litigation* are stayed pending disposition of the motion(s) to dismiss in *In re: United States Oil Fund, LP Securities Litigation*.

USCF, USO, and the other defendants intend to vigorously contest the claims in *In re United States Oil Fund, LP Derivative Litigation*.

**NOTE 8 — FAIR VALUE OF FINANCIAL INSTRUMENTS**

USO values its investments in accordance with Accounting Standards Codification 820 – Fair Value Measurements and Disclosures ("ASC 820"). ASC 820 defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value measurement. The changes to past practice resulting from the application of ASC 820 relate to the definition of fair value, the methods used to measure fair value, and the expanded disclosures about fair value measurement. ASC 820 establishes a fair value hierarchy that distinguishes between: (1) market participant assumptions developed based on market data obtained from sources independent of USO (observable inputs) and (2) USO's own assumptions about market participant assumptions developed based on the best information available under the circumstances (unobservable inputs). The three levels defined by the ASC 820 hierarchy are as follows:

Level I – Quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.

Level II – Inputs other than quoted prices included within Level I that are observable for the asset or liability, either directly or indirectly. Level II assets include the following: quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability, and inputs that are derived principally from or corroborated by observable market data by correlation or other means (market-corroborated inputs).

Level III – Unobservable pricing input at the measurement date for the asset or liability. Unobservable inputs shall be used to measure fair value to the extent that observable inputs are not available.

In some instances, the inputs used to measure fair value might fall within different levels of the fair value hierarchy. The level in the fair value hierarchy within which the fair value measurement in its entirety falls shall be determined based on the lowest input level that is significant to the fair value measurement in its entirety.

The following table summarizes the valuation of USO's securities at December 31, 2022 using the fair value hierarchy:
