ORGANIZATION AND BUSINESS
ORGANIZATION AND BUSINESS	NOTE 1 — The United States Commodity Index Funds Trust (the “Trust”) was organized as a Delaware statutory trust on December 21, 2009. The Trust is a series trust formed pursuant to the Delaware Statutory Trust Act and includes the United States Commodity Index Fund (“USCI”), a commodity pool formed on April 1, 2010 and first made available to the public on August 10, 2010, and the United States Copper Index Fund (“CPER”), a commodity pool formed on November 26, 2010 and first made available to the public on November 15, 2011. USCI and CPER each issue shares (“shares”) that are traded on the NYSE Arca, Inc. (“NYSE Arca”). USCI and CPER are collectively referred to herein as the “Trust Series.” The Trust and each of its series operates pursuant to the Fourth Amended and Restated Declaration of Trust and Trust Agreement dated as of December 15, 2017 (the “Trust Agreement”). United States Commodity Funds LLC (“USCF”) is the sponsor of the Trust and the Trust Series and is also responsible for the management of the Trust and the Trust Series. For purposes of the financial statement presentation, unless specified otherwise, all references will be to the Trust Series. USCF has the power and authority to establish and designate one or more series of the Trust and to issue shares thereof, from time to time as it deems necessary or desirable. USCF has exclusive power to fix and determine the relative rights and preferences as between the shares of any series as to right of redemption, special and relative rights as to dividends and other distributions and on liquidation, conversion rights, and conditions under which the series shall have separate voting rights or no voting rights. The term for which the Trust is to exist commenced on the date of the filing of the Certificate of Trust, and the Trust and any Trust Series will exist in perpetuity, unless earlier terminated in accordance with the provisions of the Trust Agreement. Separate and distinct records must be maintained for each Trust Series and the assets associated with a Trust Series must be held in such separate and distinct records (directly or indirectly, including a nominee or otherwise) and accounted for in such separate and distinct records separately from the assets of any other Trust Series. Each Trust Series is separate from all other Trust Series created as series of the Trust in respect of the assets and liabilities allocated to that Trust Series and represents a separate investment portfolio of the Trust. The sole Trustee of the Trust is Wilmington Trust Company (the “Trustee”), a Delaware banking corporation. The Trustee is unaffiliated with USCF. The Trustee’s duties and liabilities with respect to the offering of shares and the management of the Trust are limited to its express obligations under the Trust Agreement. USCF is a member of the National Futures Association (the “NFA”) and became a commodity pool operator (“CPO”) registered with the Commodity Futures Trading Commission (the “CFTC”) effective December 1, 2005. The Trust and each Trust Series has a fiscal year ending on December 31. USCF is also the general partner of the United States Oil Fund, LP (“USO”), 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”). USO, UNG, UGA, UNL, USL and BNO are referred to collectively herein as the “Related Public Funds.” Each of USCI and CPER issue shares to certain authorized purchasers (“Authorized Participants”) by offering baskets consisting of 50,000 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 net asset value (“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 each Trust Series a $350 transaction fee for each order placed to create one or more Creation Baskets or to redeem one or more baskets (“Redemption Baskets”), consisting of 50,000 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 each Trust Series but rather at market prices quoted on such exchange. 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.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	Jun. 30, 2024
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	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. Each Trust Series is an investment company for accounting purposes and follows the accounting and reporting guidance in FASB Topic 946. 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 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 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. Each Trust Series earns income on funds held at the custodian or a futures commission merchant (“FCM”) 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 Trust Series are not subject to federal income taxes; each investor 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, each Trust Series 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. Each Trust Series files an income tax return in the U.S. federal jurisdiction and may file income tax returns in various U.S. states. None of the Trust Series is 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 each Trust Series recording a tax liability that reduces net assets. However, each Trust Series’ 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. Each Trust Series 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 period ended June 30, 2024 for any Trust Series. Creations and Redemptions Effective as of May 1, 2012, Authorized Participants may purchase Creation Baskets or redeem Redemption Baskets for USCI and CPER only in blocks of 50,000 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. Each Trust Series 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 each Trust Series’ 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 each Trust Series a $350 transaction fee for each order placed to create one or more Creation Baskets or to redeem one or more Redemption Baskets. Trust Capital and Allocation of Income and Losses Profit or loss shall be allocated among the shareholders of each Trust Series in proportion to the weighted-average number of shares each investor holds as of the close of each month. USCF may revise, alter or otherwise modify this method of allocation as described in the Trust Agreement. Calculation of Per Share NAV Each Trust Series’ 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. Each Trust Series uses the closing prices on the relevant Futures Exchanges (as defined in Note 3 below) of the Applicable Benchmark Component Futures Contracts (as defined in Note 3 below) that at any given time make up the Applicable Index (as defined in Note 3 below) (determined at the earlier of the close of such exchange or 2:30 p.m. New York time) for the contracts traded on the Futures Exchanges, but calculates or determines the value of all other investments of each Trust Series using market quotations, if available, or other information customarily used to determine the fair value of such investments. 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. As of June 30, 2024, USCF held 5 shares of USCI and 40 shares of CPER. Offering Costs Offering costs incurred in connection with the registration of shares prior to the commencement of the offering are borne by USCF. Offering costs incurred in connection with the registration of additional shares after the commencement of the offering are borne by each Trust Series. These costs include registration fees paid to regulatory agencies and all legal, accounting, printing and other expenses associated with such offerings. Costs borne by the Trust Series after the commencement of an offering 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. 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.

TRUST SERIES
TRUST SERIES	NOTE 3 — TRUST SERIES In connection with the execution of the First Trust Agreement on April 1, 2010, USCI was designated as the first series of the Trust. USCF contributed $1,000 to the Trust upon its formation on December 21, 2009, representing an initial contribution of capital to the Trust. Following the designation of USCI as the first series of the Trust, the initial capital contribution of $1,000 was transferred from the Trust to USCI and deemed an initial contribution to USCI. In connection with the commencement of USCI’s initial offering of shares, USCF received 20 Sponsor Shares of USCI in exchange for the previously received capital contribution, representing a beneficial ownership interest in USCI. On July 30, 2010, USCI received a notice of effectiveness from the SEC for its registration of 50,000,000 shares on Form S-1 with the SEC. On August 10, 2010, USCI listed its shares on the NYSE Arca under the ticker symbol “USCI”. USCI established its initial per share NAV by setting the price at $50.00 and issued 100,000 shares in exchange for $5,000,000 on August 10, 2010. USCI also commenced investment operations on August 10, 2010 by purchasing Futures Contracts traded on the Futures Exchanges. In order to satisfy NYSE Arca listing standards that at least 100,000 shares be outstanding at the beginning of the trading day on the NYSE Arca, USCF purchased the initial Creation Basket from the initial Authorized Participant at the initial offering price. The $1,000 fee that would otherwise be charged to the Authorized Participant in connection with an order to create or redeem was waived in connection with the initial Creation Basket. USCF held such initial Creation Basket until September 3, 2010, at which time the initial Authorized Participant repurchased the shares comprising such basket in accordance with the specified conditions noted above. On September 14, 2011, USCF redeemed the 20 Sponsor Shares of USCI and, on September 19, 2011, USCF purchased 5 shares of USCI in the open market. In connection with the Second Amended and Restated Trust Agreement dated November 10, 2010, CPER was designated as additional series of the Trust. USCF and the Trustee entered into the Fourth Amended and Restated Declaration of Trust and Trust Agreement effective as of December 15, 2017. Following the designation of CPER as an additional series, USCF made an initial capital contribution to the Trust and on November 10, 2010, the Trust transferred $1,000 to CPER, which was deemed a capital contribution to the series. On November 14, 2011, USCF received 40 Sponsor Shares of CPER in exchange for the previously received capital contribution, representing a beneficial interest in CPER. On December 7, 2011, USCF redeemed the 40 Sponsor Shares of CPER and purchased 40 shares of CPER in the open market. CPER received notice of effectiveness from the SEC for its registration of 30,000,000 CPER shares September 6, 2011. The order to permit listing CPER on the NYSE Arca was received on October 20, 2011. On November 15, 2011, CPER listed its shares on the NYSE Arca under the ticker symbol “CPER.” CPER established its initial per share NAV by setting the price at $25 and issued 100,000 shares to the initial Authorized Participant, Merrill Lynch Professional Clearing Corp., in exchange for $2,500,000 in cash on November 15, 2011. The $1,000 fee that would otherwise be charged to the Authorized Participant in connection with an order to create or redeem was waived in connection with the initial Creation Basket. USCI’s Investment Objective The investment objective of USCI 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 SummerHaven Dynamic Commodity Index Total Return SM The SDCI is designed to reflect the performance of a diversified group of commodities. The SDCI is owned and maintained by SummerHaven Index Management, LLC (“SHIM”) and is calculated and published by Bloomberg L.P. Futures contracts for the commodities comprising the SDCI are traded on the New York Mercantile Exchange (“NYMEX”), ICE Futures (“ICE Futures”), Chicago Board of Trade (“CBOT”), Chicago Mercantile Exchange (“CME”), London Metal Exchange (“LME”), and Commodity Exchange, Inc. (“COMEX” together with the NYMEX, ICE Futures, CBOT, CME and LME, the “Futures Exchanges”) and are collectively referred to herein as “Futures Contracts.” The Futures Contracts that at any given time make up the SDCI are referred to herein as “Benchmark Component Futures Contracts.” The relative weighting of the Benchmark Component Futures Contracts will change on a monthly basis, based on quantitative formulas relating to the prices of the Benchmark Component Futures Contracts developed by SHIM. USCI seeks to achieve its investment objective by investing primarily in the Benchmark Component Futures Contracts. Then, if constrained by regulatory requirements, risk mitigation measures (including those that may be taken by USCI, USCI’s FCMs, counterparties or other market participants), liquidity requirements, or in view of market conditions, USCI will invest next in other Futures Contracts based on the same commodity as the futures contracts subject to such regulatory constraints or market conditions, and finally, to a lesser extent, in other exchange-traded futures contracts that are economically identical or substantially similar to the Benchmark Component Futures Contracts if one or more other Futures Contracts is not available. When USCI has invested to the fullest extent possible in exchange-traded futures contracts, USCI may then invest in other contracts and instruments based on the Benchmark Component Futures Contracts, other Futures Contracts or the commodities included in the SDCI, such as cash-settled options, forward contracts, cleared swap contracts and swap contracts other than cleared swap contracts. Other exchange-traded futures contracts that are economically identical or substantially similar to the Benchmark Component Futures Contracts and other contracts and instruments based on the Benchmark Component Futures Contracts are collectively referred to as “Other Commodity-Related Investments,” and together with Benchmark Component Futures Contracts and other Futures Contracts, “Commodity Interests.” USCI seeks to achieve its investment objective by investing so that the average daily percentage change in USCI’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 SDCI over the same period. As a result, investors should be aware that USCI 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 SDCI, provided that the average daily percentage change in USCI’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 SDCI over the same period. USCF believes that the market arbitrage opportunities will cause the daily changes in USCI’s share price on the NYSE Arca on a percentage basis to closely track the daily changes in USCI’s per share NAV on a percentage basis. USCF believes that the net effect of this expected relationship and the expected relationship described above between USCI’s per share NAV and the SDCI will be that the daily changes in the price of USCI’s shares on the NYSE Arca on a percentage basis will closely track the daily changes in the SDCI on a percentage basis, less USCI’s expenses. While USCI is composed of Benchmark Component Futures Contracts and is therefore a measure of the prices of the corresponding commodities comprising the SDCI for future delivery, there is nonetheless expected to be a reasonable degree of correlation between the SDCI and the cash or spot prices of the commodities underlying the Benchmark Component Futures Contracts. Investors should be aware that USCI’s investment objective is not for its NAV or market price of shares to equal, in dollar terms, the spot prices of the commodities underlying the Benchmark Component Futures Contracts or the prices of any particular group of futures contracts. USCI will not seek to achieve its stated investment objective over a period of time greater than one day. This is because natural market forces called contango and backwardation have impacted the total return on an investment in USCI’s shares during the past year relative to a hypothetical direct investment in the various commodities and, in the future, it is likely that the relationship between the market price of USCI’s shares and changes in the spot prices of the underlying commodities will continue to be impacted by contango and backwardation. (It is important to note that the disclosure above ignores the potential costs associated with physically owning and storing the commodities, which could be substantial.) USCI’s shares began trading on August 10, 2010. As of June 30, 2024, USCI held 293 Futures Contracts on the NYMEX, held 997 Futures Contracts on the ICE Futures, held 619 Futures Contracts on the CBOT, held 557 Futures Contracts on the CME, held 240 Futures Contracts on the LME and held 176 Futures Contracts on the COMEX, totaling 2,882 futures contracts. CPER’s Investment Objective The investment objective of CPER is for the daily changes in percentage terms of its shares’ per share NAV to reflect the daily changes in percentage terms of the SummerHaven Copper Index Total Return SM The SCI is designed to reflect the performance of the investment returns from a portfolio of copper futures contracts on the COMEX. The SCI is owned and maintained by SHIM and calculated and published by the NYSE Arca. The SCI is comprised of either one or three Eligible Copper Futures Contracts that are selected on a monthly basis based on quantitative formulas relating to the prices of the Eligible Copper Futures Contracts developed by SHIM. The Eligible Copper Futures Contracts that at any given time make up the SCI are referred to herein as “Benchmark Component Copper Futures Contracts.” CPER seeks to achieve its investment objective by investing primarily in Benchmark Component Copper Futures Contracts. CPER may also, to a lesser extent, invest in other Eligible Copper Futures Contracts beyond the Benchmark Component Copper Futures Contracts or other exchange-traded futures contracts that are economically identical or substantially similar to the Benchmark Component Copper Futures Contracts, as well as other investments based on copper, such as cash-settled options on Benchmark Component Copper Futures Contracts, forward contracts for copper, cleared swap contracts, non-cleared “over-the-counter” or “OTC” transactions that are based on the price of copper and other Benchmark Component Copper Futures Contracts and indices based on the foregoing (collectively, “Other Copper-Related Investments”). The following factors, among others, may be considered when determining CPER’s investments in Eligible Copper Futures Contracts or in Other Copper-Related Investments: regulatory requirements, risk mitigation measures taken by CPER, CPER’s FCMs, counterparties or other market participants, liquidity and market conditions. Other factors that may impact CPER’s investments in other Eligible Copper Futures Contracts, other exchange-traded futures contracts, or Other Copper-Related Investments include allowing CPER to obtain greater liquidity or to execute transactions with more favorable pricing. In addition, CPER 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 the changes in market conditions, regulatory requirements or risk mitigation measures or the need to satisfy potential margin requirements. For convenience and unless otherwise specified, Benchmark Component Copper Futures Contracts, other Eligible Copper Futures Contracts and Other Copper-Related Investments collectively are referred to as “Copper Interests.” CPER seeks to achieve its investment objective by investing so that the average daily percentage change in CPER’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 prices of the Benchmark Component Copper Futures Contracts over the same period. As a result, investors should be aware that CPER 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 SCI, provided that the average daily percentage change in CPER’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 SCI over the same period. USCF believes that market arbitrage opportunities will cause daily changes in CPER’s share price on the NYSE Arca on a percentage basis, to closely track the daily changes in CPER’s per share NAV on a percentage basis. USCF believes that the net effect of this expected relationship and the expected relationship described above between CPER’s per share NAV and the SCI will be that the daily changes in the price of CPER’s shares on the NYSE Arca on a percentage basis will closely track the daily changes in the SCI on a percentage basis, less CPER’s expenses. While CPER is composed of Benchmark Component Copper Futures Contracts and is therefore a measure of the prices of the corresponding commodities comprising the SCI for future delivery, there is nonetheless expected to be a reasonable degree of correlation between the SCI and the cash or spot prices of the commodities underlying the Benchmark Component Copper Futures Contracts. Investors should be aware that CPER’s investment objective is not for its NAV or market price of shares to equal, in dollar terms, the spot prices of the commodities underlying the Benchmark Component Copper Futures Contracts or the prices of any particular group of futures contracts. CPER will not seek to achieve its stated investment objective over a period of time greater than one day. This is because natural market forces called contango and backwardation have impacted the total return on an investment in CPER’s shares during the past year relative to a hypothetical direct investment in various commodities and, in the future, it is likely that the relationship between the market price of CPER’s shares and changes in the spot prices of the underlying commodities will continue to be so impacted by contango and backwardation.

FEES PAID BY EACH TRUST SERIES AND RELATED PARTY TRANSACTIONS
FEES PAID BY EACH TRUST SERIES AND RELATED PARTY TRANSACTIONS	NOTE 4 — FEES PAID BY EACH TRUST SERIES AND RELATED PARTY TRANSACTIONS USCF Management Fee Under the Trust Agreement, USCF is responsible for investing the assets of each Trust Series in accordance with the objectives and policies of each such Trust Series. In addition, USCF has arranged for one or more third parties to provide trading advisory, administrative, custody, accounting, transfer agency and other necessary services to each Trust Series. For these services, each of USCI and CPER is contractually obligated to pay USCF a management fee of 0.80% (80 basis points) per annum of average daily total net assets for USCI and 0.65% (65 basis points) per annum of average daily total net assets for CPER. Trustee Fee The Trustee is the Delaware trustee of the Trust. In connection with the Trustee’s services, USCF is responsible for paying the Trustee’s annual fee in the amount of $3,300. Ongoing Registration Fees and Other Offering Expenses Each Trust Series pays the costs and expenses associated with the ongoing registration of its shares subsequent to the initial offering.

On April 30, 2021, 10,000,000 additional shares were registered for USCI and 50,000,000 additional shares were registered for CPER. On January 27, 2023 the SEC declared effective registration statements filed by each of USCI and CPER that registered an unlimited number of shares. As a result, USCI and CPER each have an unlimited number of shares that can be issued in the form of Creation Baskets. Independent Directors’ and Officers’ Expenses Each Trust Series is responsible for paying its portion of the directors’ fees and directors’ and officers’ liability insurance for such Trust Series and the Related Public Funds. Each Trust Series shares the fees and expenses on a pro rata basis with each Trust Series and each Related Public Fund, as described above, based on the relative assets of each fund computed on a daily basis. These fees and expenses for the year ending December 31, 2024 are estimated to be a total of $ 945,000 for the Trust Series and the Related Public Funds. USCI’s portion of such fees and expenses for the year ending December 31, 2024 are estimated to be $52,000 and CPER’s portion of such fees and expenses for the year ending December 31, 2024 are estimated to be $49,000 .

FINANCIAL INSTRUMENTS, OFF-BALANCE SHEET RISKS AND CONTINGENCIES
FINANCIAL INSTRUMENTS, OFF-BALANCE SHEET RISKS AND CONTINGENCIES	NOTE 6 — FINANCIAL INSTRUMENTS, OFF-BALANCE SHEET RISKS AND CONTINGENCIES Each Trust Series engages in the trading of futures contracts, options on futures contracts, cleared swaps and OTC swaps (collectively, “derivatives”). As such, each Trust Series 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. Each Trust Series may enter into futures contracts, options on futures contracts and cleared 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. 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 an FCM to segregate all customer transactions and assets from the FCM’s proprietary transactions and assets. 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 each Trust Series 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. All of the futures contracts held by each Trust Series through June 30, 2024 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. However, in the future, if each Trust Series were to enter into non-exchange traded contracts (including Exchange for Related Position or EFRP), 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, on the transaction. Currently, each Trust Series has credit risk under its futures contracts since the sole counterparty to all domestic and foreign futures contracts is the clearinghouse for the exchange on which the relevant contracts are traded. In addition, each Trust Series bears the risk of financial failure by the clearing broker. Significant market volatility can occur in the commodity markets and the commodity futures markets. Such volatility can be caused by events such as the COVID-19 pandemic, related supply chain disruptions, war, including the Russia-Ukraine war, attacks or threats of attack by terrorists, conflicts in the Middle East, and disputes among commodity-producing countries. Events such as these can increase volatility, which may affect the value, pricing and liquidity of some investments or other assets, including those held by or invested in by a Trust Series and have a negative impact on such Trust Series or its ability to have all of its assets invested in the Benchmark Component Futures Contracts. A Trust Series’ cash and other property, such as Treasuries, deposited with an FCM are considered commingled with all other customer funds, subject to the 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 a Trust Series’ assets posted with that FCM; however, the majority of each Trust Series’ assets are held in investments in Treasuries, cash and/or cash equivalents with the Trust Series’ custodian and would not be impacted by the insolvency of an FCM. The failure or insolvency of the Trust Series’ custodian, however, could result in a substantial loss of each Trust Series’ assets. USCF may invest a portion of each Trust Series’ cash in money market funds that seek to maintain a stable per share NAV. Each Trust Series may be exposed to any risk of loss associated with an investment in such money market funds. As of June 30, 2024 and December 31, 2023, USCI held investments in money market funds in the amounts of $68,800,000 and $55,800,000, respectively. As of June 30, 2024 and December 31,2023, CPER held investments in money market funds in the amounts of $52,950,000 and $32,950,000, respectively. Each Trust Series also holds cash deposits with its custodian. As of June 30, 2024 and December 31, 2023, USCI held cash deposits and investments in Treasuries in the amounts of $117,464,777 and $116,309,309, respectively, with the custodian and FCMs. As of June 30, 2024 and December 31, 2023, CPER held cash deposits and investments in Treasuries in the amounts of $166,705,883 and $94,151,194, respectively, with the custodian and FCMs. Some or all of these amounts may be subject to loss should the Trust Series’ custodian and/or FCMs cease operations. For derivatives, risks arise from changes in the market value of the contracts. Theoretically, each Trust Series is exposed to 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, each Trust Series 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 Trust Series’ 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 Trust Series or USCF have a policy of requiring review of the credit standing of each broker or counterparty with which they conduct business. The financial instruments held by the applicable Trust Series are reported in its condensed 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.

FAIR VALUE OF FINANCIAL INSTRUMENTS
FAIR VALUE OF FINANCIAL INSTRUMENTS	NOTE 8 — FAIR VALUE OF FINANCIAL INSTRUMENTS The Trust and each Trust Series value their 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 the Trust and each Trust Series (observable inputs) and (2) the Trust’s and each Trust Series’ 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 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 USCI’s securities at June 30, 2024 using the fair value hierarchy: At June 30, 2024 Total Level I Level II Level III Short-Term Investments $ 130,553,243 $ 130,553,243 $ — $ — Exchange-Traded Futures Contracts United States Contracts (3,405,486) (3,405,486) — — Foreign Contracts 761,667 761,667 — — The following table summarizes the valuation of USCI’s securities at December 31, 2023 using the fair value hierarchy: At December 31, 2023 Total Level I Level II Level III Short-Term Investments $ 98,508,636 $ 98,508,636 $ — $ — Exchange-Traded Futures Contracts United States Contracts (3,158,862) (3,158,862) — — Foreign Contracts (146,218) (146,218) — — The following table summarizes the valuation of CPER’s securities at June 30, 2024 using the fair value hierarchy: At June 30, 2024 Total Level I Level II Level III Short-Term Investments $ 140,576,336 $ 140,576,336 $ — $ — Exchange-Traded Futures Contracts United States Contracts (3,066,813) (3,066,813) — — The following table summarizes the valuation of CPER’s securities at December 31, 2023 using the fair value hierarchy: At December 31, 2023 Total Level I Level II Level III Short-Term Investments $ 53,758,687 $ 53,758,687 $ — $ — Exchange-Traded Futures Contracts United States Contracts 3,996,334 3,996,334 — — The Trust and each Trust Series have adopted the provisions of Accounting Standards Codification 815 — Derivatives and Hedging, which require presentation of qualitative disclosures about objectives and strategies for using derivatives, quantitative disclosures about fair value amounts and gains and losses on derivatives.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	6 Months Ended
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	Jun. 30, 2024
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Basis of Presentation	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. Each Trust Series is an investment company for accounting purposes and follows the accounting and reporting guidance in FASB Topic 946.
Revenue Recognition	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 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 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. Each Trust Series earns income on funds held at the custodian or a futures commission merchant (“FCM”) at prevailing market rates earned on such investments.
Brokerage Commissions	Brokerage Commissions Brokerage commissions on all open commodity futures contracts are accrued on a full-turn basis.
Income Taxes	Income Taxes The Trust Series are not subject to federal income taxes; each investor 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, each Trust Series 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. Each Trust Series files an income tax return in the U.S. federal jurisdiction and may file income tax returns in various U.S. states. None of the Trust Series is 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 each Trust Series recording a tax liability that reduces net assets. However, each Trust Series’ 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. Each Trust Series 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 period ended June 30, 2024 for any Trust Series.
Creations and Redemptions	Creations and Redemptions Effective as of May 1, 2012, Authorized Participants may purchase Creation Baskets or redeem Redemption Baskets for USCI and CPER only in blocks of 50,000 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. Each Trust Series 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 each Trust Series’ 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 each Trust Series a $350 transaction fee for each order placed to create one or more Creation Baskets or to redeem one or more Redemption Baskets.
Trust Capital and Allocation of Income and Losses	Trust Capital and Allocation of Income and Losses Profit or loss shall be allocated among the shareholders of each Trust Series in proportion to the weighted-average number of shares each investor holds as of the close of each month. USCF may revise, alter or otherwise modify this method of allocation as described in the Trust Agreement.
Calculation of Per Share NAV	Calculation of Per Share NAV Each Trust Series’ 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. Each Trust Series uses the closing prices on the relevant Futures Exchanges (as defined in Note 3 below) of the Applicable Benchmark Component Futures Contracts (as defined in Note 3 below) that at any given time make up the Applicable Index (as defined in Note 3 below) (determined at the earlier of the close of such exchange or 2:30 p.m. New York time) for the contracts traded on the Futures Exchanges, but calculates or determines the value of all other investments of each Trust Series using market quotations, if available, or other information customarily used to determine the fair value of such investments.
Net Income (Loss) Per Share	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. As of June 30, 2024, USCF held 5 shares of USCI and 40 shares of CPER.
Offering Costs	Offering Costs Offering costs incurred in connection with the registration of shares prior to the commencement of the offering are borne by USCF. Offering costs incurred in connection with the registration of additional shares after the commencement of the offering are borne by each Trust Series. These costs include registration fees paid to regulatory agencies and all legal, accounting, printing and other expenses associated with such offerings. Costs borne by the Trust Series after the commencement of an offering 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 Cash equivalents include money market funds and overnight deposits or time deposits with original maturity dates of six months or less.
Use of Estimates	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.
