ORGANIZATION AND BUSINESS

ORGANIZATION AND BUSINESS	Dec. 31, 2019
ORGANIZATION AND BUSINESS
ORGANIZATION AND BUSINESS	NOTE 1 — ORGANIZATION AND BUSINESS The United States Gasoline Fund, LP (“UGA”) was organized as a limited partnership under the laws of the state of Delaware on April 13, 2007. UGA is a commodity pool that issues limited partnership shares (“shares”) that may be purchased and sold on the NYSE Arca, Inc. (the “NYSE Arca”). Prior to November 25, 2008, UGA’s shares traded on the American Stock Exchange (the “AMEX”). UGA will continue in perpetuity, unless terminated sooner upon the occurrence of one or more events as described in its Third Amended and Restated Agreement of Limited Partnership dated as of December 15, 2017 (the “LP Agreement”). The investment objective of UGA 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 gasoline (also known as reformulated gasoline blendstock for oxygen blending, or “RBOB”, for delivery to the New York harbor), as measured by the daily changes in the price of the futures contract for gasoline 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 (the “Benchmark Futures Contract”), plus interest earned on UGA’s collateral holdings, less UGA’s expenses. UGA’s investment objective is not for its NAV or market price of shares to equal, in dollar terms, the spot price of gasoline or any particular futures contract based on gasoline, nor is UGA’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. United States Commodity Funds LLC (“USCF”), the general partner of UGA, believes that it is not practical to manage the portfolio to achieve such an investment goal when investing in Futures Contracts (as defined below) and Other Gasoline-Related Investments (as defined below). UGA accomplishes its objective through investments in futures contracts for gasoline, crude oil, natural gas, diesel-heating oil and other petroleum-based fuels that are traded on the NYMEX, ICE Futures or other U.S. and foreign exchanges (collectively, “Futures Contracts”) and other gasoline-related investments such as cash-settled options on Futures Contracts, forward contracts for gasoline, cleared swap contracts and over-the-counter (“OTC”) transactions that are based on the price of gasoline, crude oil and other petroleum-based fuels, Futures Contracts and indices based on the foregoing (collectively, “Other Gasoline-Related Investments”). As of December 31, 2019, UGA held 410 Futures Contracts for gasoline traded on the NYMEX and did not hold any Futures Contracts traded on the ICE Futures. UGA commenced investment operations on February 26, 2008 and has a fiscal year ending on December 31. USCF is responsible for the management of UGA. 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 Oil Fund, LP (“USO”), the United States Natural Gas Fund, LP (“UNG”) and the United States 12 Month Oil Fund, LP (“USL”), which listed their limited partnership shares on the AMEX under the ticker symbols “USO” on April 10, 2006, “UNG” on April 18, 2007 and “USL” on December 6, 2007, respectively. As a result of the acquisition of the AMEX by NYSE Euronext, each of USO’s, UNG’s, and USL’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 previously served as the general partner for the United States Short Oil Fund, LP (“DNO”) and the United States Diesel-Heating Oil Fund, LP (“UHN”), both of which were liquidated in 2018. USCF is also the sponsor of the United States Commodity Index Fund (“USCI”), the United States Copper Index Fund (“CPER”) and the USCF Crescent Crypto Index Fund (“XBET”), each a series of the United States Commodity Index Funds Trust (“USCIFT”). USCF previously served as the sponsor for the United States Agricultural Index Fund (“USAG”) a series of USCIFT which was liquidated in 2018. XBET is currently in registration and has not commenced operations. 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. In addition, USCF is the sponsor of the USCF Funds Trust, a Delaware statutory trust, and each of its series, the United States 3x Oil Fund (“USOU”) and the United States 3x Short Oil Fund (“USOD”), which listed their shares on the NYSE Arca on July 20, 2017 under the ticker symbols “USOU” and “USOD”, respectively. Each of USOU and USOD liquidated all of its assets and distributed cash pro rata to all remaining shareholders in December 2019. USO, UNG, UGA, UNL, USL, BNO, USCI and CPER are referred to collectively herein as the “Related Public Funds.” UGA issues 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 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 UGA a $350 transaction fee for each order placed to create one or more Creation Baskets or to redeem one or more Redemption Baskets. 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 UGA but rather at market prices quoted on such exchange. In November 2007, UGA initially registered 30,000,000 shares on Form S‑1 with the U.S. Securities and Exchange Commission (“SEC”). On February 26, 2008, UGA listed its shares on the AMEX under the ticker symbol “UGA” and switched to trading on the NYSE Arca under the same ticker symbol on November 25, 2008. On that day, UGA established its’ initial per share NAV by setting the price at $50.00 and issued 300,000 shares in exchange for $15,000,000. UGA also commenced investment operations on February 26, 2008 by purchasing Futures Contracts traded on the NYMEX based on gasoline. As of December 31, 2019, UGA had registered a total of 80,000,000 shares.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	NOTE 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America ("U.S. GAAP") as detailed in the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification. UGA is an investment company 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 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 financial statements. Changes in the unrealized gains or losses between periods are reflected in the statements of operations. UGA 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 UGA 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, UGA 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. UGA files an income tax return in the U.S. federal jurisdiction and may file income tax returns in various U.S. states. UGA is not subject to income tax return examinations by major taxing authorities for years before 2016. 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 UGA recording a tax liability that reduces net assets. However, UGA’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. UGA 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, 2019. Creations and Redemptions Authorized Participants may purchase Creation Baskets or redeem Redemption Baskets 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. UGA 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 UGA’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 UGA a $350 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 UGA 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 UGA’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. UGA 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, 2019. Offering Costs Offering costs incurred in connection with the registration of additional shares after the initial registration of shares are borne by UGA. 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.

Independent Directors’ and Officers’ Expenses UGA is responsible for paying its portion of the directors’ and officers’ liability insurance for UGA and the Related Public Funds and the fees and expenses of the independent directors who also serve as audit committee members of UGA and the Related Public Funds. UGA shares the fees and expenses on a pro rata basis with each 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 ended December 31, 2019 were $556,951 for UGA and the Related Public Funds.

During the years ended December 31, 2019, 2018 and 2017, UGA incurred $5,492, $6,537 and $9,033, respectively, under this arrangement. Investor Tax Reporting Cost The fees and expenses associated with UGA’s audit expenses and tax accounting and reporting requirements are paid by UGA. These costs were approximately $65,523 for the year ended December 31, 2019, approximately $150,695 for the year ended December 31, 2018 and approximately $170,000 for the year ended December 31, 2017. Tax reporting costs fluctuate between years due to the number of shareholders during any given year. Other Expenses and Fees and Expense Waivers In addition to the fees described above, UGA pays all brokerage fees and other expenses in connection with the operation of UGA, excluding costs and expenses paid by USCF as outlined in Note 4 – Contracts and Agreements below. USCF paid certain expenses on a discretionary basis typically borne by UGA, where expenses exceed 0.15% (15 basis points) of UGA’s NAV, on an annualized basis. USCF has no obligation to continue such payments into subsequent periods. For the year ended December 31, 2019, USCF waived $66,155 of UGA’s expenses. This voluntary expense waiver is in addition to those amounts USCF is contractually obligated to pay as described in Note 4 – Contracts and Agreements .

For the Year Ended For the Year Ended For the Year Ended December 31, 2019 December 31, 2018 December 31, 2017 Total commissions accrued to brokers $ 41,772 $ 42,294 $ 71,846 Total commissions as annualized percentage of average total net assets 0.11 % 0.10 % 0.12 % Commissions accrued as a result of rebalancing $ 39,760 $ 40,992 $ 67,782 Percentage of commissions accrued as a result of rebalancing 95.18 % 96.92 % 94.34 % Commissions accrued as a result of creation and redemption activity $ 2,012 $ 1,302 $ 4,064 Percentage of commissions accrued as a result of creation and redemption activity 4.82 % 3.08 % 5.66 % The decrease in total commissions accrued to brokers for the year ended December 31, 2019, compared to the year ended December 31, 2018, was due primarily to a lower number of gasoline futures contracts being held and traded. The decrease in total commissions accrued to brokers for the year ended December 31, 2018, compared to the year ended December 31, 2017, was due primarily to lower number of futures contracts being held and traded. However, there can be no assurance that commission costs and portfolio turnover will not cause commission expenses to rise in future quarters. NYMEX Licensing Agreement UGA and the NYMEX entered into a licensing agreement on April 10, 2006, as amended on October 20, 2011, whereby UGA was granted a non-exclusive license to use certain of the NYMEX’s settlement prices and service marks. Under the licensing agreement, UGA and the Related Public Funds, other than BNO, USCI, CPER, USOU and USOD, pay the NYMEX an asset-based fee for the license, the terms of which are described in Note 3. UGA expressly disclaims any association with the NYMEX or endorsement of UGA by the NYMEX and acknowledges that “NYMEX” and “New York Mercantile Exchange” are registered trademarks of the NYMEX.

FINANCIAL INSTRUMENTS, OFF-BALANCE SHEET RISKS AND CONTINGENCIES
FINANCIAL INSTRUMENTS, OFF-BALANCE SHEET RISKS AND CONTINGENCIES	NOTE 5 — FINANCIAL INSTRUMENTS, OFF-BALANCE SHEET RISKS AND CONTINGENCIES UGA may engage in the trading of futures contracts, options on futures contracts, cleared swaps and OTC swaps (collectively, “derivatives”). UGA 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. UGA 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 activities. 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 UGA 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 UGA through December 31, 2019 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 UGA were to enter into non-exchange traded contracts, it would be subject to the credit risk associated with counterparty non-performance. The credit risk from counterparty non-performance associated with such instruments is the net unrealized gain, if any, on the transaction. UGA 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, UGA bears the risk of financial failure by the clearing broker. UGA’s 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 UGA’s assets posted with that FCM; however, the majority of UGA’s assets are held in investments in Treasuries, cash and/or cash equivalents with UGA’s custodian and would not be impacted by the insolvency of an FCM. The failure or insolvency of UGA’s custodian, however, could result in a substantial loss of UGA’s assets. USCF invests a portion of UGA’s cash in money market funds that seek to maintain a stable per share NAV. UGA is exposed to any risk of loss associated with an investment in such money market funds. As of December 31, 2019, UGA held investments in money market funds in the amount of $4,100,000. As of December 31, 2018, UGA did not hold any investments in money market funds. UGA also holds cash deposits with its custodian. Pursuant to a written agreement with BBH&Co., uninvested overnight cash balances are swept to offshore branches of U.S. regulated and domiciled banks located in Toronto, Canada; London, United Kingdom; Grand Cayman, Cayman Islands; and Nassau, Bahamas; which are subject to U.S. regulation and regulatory oversight. As of December 31, 2019 and December 31, 2018, UGA held cash deposits and investments in Treasuries in the amounts of $25,575,052 and $34,253,119, respectively, with the custodian and FCM. Some or all of these amounts may be subject to loss should UGA’s custodian and/or FCM cease operations. For derivatives, risks arise from changes in the market value of the contracts. Theoretically, UGA 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, UGA 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. UGA’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, UGA 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 UGA 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.

FAIR VALUE OF FINANCIAL INSTRUMENTS
FAIR VALUE OF FINANCIAL INSTRUMENTS	NOTE 8 — FAIR VALUE OF FINANCIAL INSTRUMENTS UGA 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 UGA (observable inputs) and (2) UGA’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 UGA’s securities at December 31, 2019 using the fair value hierarchy: At December 31, 2019 Total Level I Level II Level III Short-Term Investments $ 28,999,188 $ 28,999,188 $ — $ — Exchange-Traded Futures Contracts Foreign Contracts 10,332 10,332 — — During the year ended December 31, 2019, there were no transfers between Level I and Level II.

RECENT ACCOUNTING PRONOUNCEMENTS	NOTE 9 - RECENT ACCOUNTING PRONOUNCEMENTS In August 2018, the FASB issued Accounting Standards Update (“ASU”) No. 2018-13, which changes certain fair value measurement disclosure requirements. The new ASU, in addition to other modifications and additions, removes the requirement to disclose the amount and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, and the Funds’ policy for the timing of transfers between levels. The amendments are effective for financial statements issued for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. The Fund has evaluated the implications of certain provisions of the ASU and has determined that there will be no material impacts to the financial statements.

SUMMARY OF SIGNIFICANT ACCOUN_2

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	Dec. 31, 2019
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Basis of Presentation	Basis of Presentation The financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America ("U.S. GAAP") as detailed in the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification. UGA is an investment company 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 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 financial statements. Changes in the unrealized gains or losses between periods are reflected in the statements of operations. UGA 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 UGA 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, UGA 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. UGA files an income tax return in the U.S. federal jurisdiction and may file income tax returns in various U.S. states. UGA is not subject to income tax return examinations by major taxing authorities for years before 2016. 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 UGA recording a tax liability that reduces net assets. However, UGA’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. UGA 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, 2019.
Creations and Redemptions	Creations and Redemptions Authorized Participants may purchase Creation Baskets or redeem Redemption Baskets 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. UGA 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 UGA’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 UGA a $350 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	Partnership Capital and Allocation of Partnership Income and Losses Profit or loss shall be allocated among the partners of UGA 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	Calculation of Per Share NAV UGA’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. UGA 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 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, 2019.
Offering Costs	Offering Costs Offering costs incurred in connection with the registration of additional shares after the initial registration of shares are borne by UGA. 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 Cash equivalents include money market funds and overnight deposits or time deposits with original maturity dates of six months or less.
Reclassification	Reclassification Certain amounts in the accompanying financial statements were reclassified to conform to the current presentation.
Use of Estimates	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.
