Notes to Condensed Financial Statements

For the period ended June 30, 2013 (Unaudited)

NOTE 1 — ORGANIZATION AND BUSINESS

The United States 12 Month Oil Fund, LP (“US12OF”) was organized as a limited partnership under the laws of the state of Delaware on June 27, 2007. US12OF is a commodity pool that issues limited partnership units (“units”) that may be purchased and sold on the NYSE Arca, Inc. (the “NYSE Arca”). Prior to November 25, 2008, US12OF’s units traded on the American Stock Exchange (the “AMEX”). US12OF will continue in perpetuity, unless terminated sooner upon the occurrence of one or more events as described in its Second Amended and Restated Agreement of Limited Partnership dated as of March 1, 2013 (the “LP Agreement”). The investment objective of US12OF is for the daily changes in percentage terms of its units’ per unit 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 average of the prices of the 12 futures contracts for light, sweet crude oil traded on the New York Mercantile Exchange (the “NYMEX”), consisting of the near month contract to expire and the contracts for the following 11 months for a total of 12 consecutive months’ contracts, 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 and the contracts for the following 11 consecutive months (the “Benchmark Futures Contracts”), less US12OF’s expenses. When calculating the daily movement of the average price of the 12 contracts, each contract month will be equally weighted. It is not the intent of US12OF to be operated in a fashion such that the per unit NAV will equal, in dollar terms, the spot price of light, sweet crude oil or any particular futures contract based on light, sweet crude oil. It is not the intent of US12OF to be operated in a fashion such that its per unit NAV will reflect the percentage change of the price of any particular futures contracts as measured over a time period greater than one day. United States Commodity Funds LLC (“USCF”), the general partner of US12OF, believes that it is not practical to manage the portfolio to achieve such an investment goal when investing in Oil Futures Contracts (as defined below) and Other Oil-Related Investments (as defined below). US12OF 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 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 June 30, 2013, US12OF held 772 Oil Futures Contracts for light, sweet crude oil traded on the NYMEX and did not hold any Oil Futures Contracts traded on the ICE Futures.

US12OF commenced investment operations on December 6, 2007 and has a fiscal year ending on December 31. USCF is responsible for the management of US12OF. USCF is a member of the National Futures Association (the “NFA”) and became a commodity pool operator registered with the Commodity Futures Trading Commission (the “CFTC”) effective December 1, 2005. USCF is also the general partner of the United States Oil Fund, LP (“USOF”), the United States Natural Gas Fund, LP (“USNG”), the United States Gasoline Fund, LP (“UGA”) and the United States Diesel-Heating Oil Fund, LP (formerly, the United States Heating Oil Fund, LP) (“USDHO”), which listed their limited partnership units on the AMEX under the ticker symbols “USO” on April 10, 2006, “UNG” on April 18, 2007, “UGA” on February 26, 2008 and “UHN” on April 9, 2008, respectively. As a result of the acquisition of the AMEX by NYSE Euronext, each of USOF’s, USNG’s, UGA’s and USDHO’s units commenced trading on the NYSE Arca on November 25, 2008. USCF is also the general partner of the United States Short Oil Fund, LP (“USSO”), the United States 12 Month Natural Gas Fund, LP (“US12NG”) and the United States Brent Oil Fund, LP (“USBO”), which listed their limited partnership units on the NYSE Arca under the ticker symbols “DNO” on September 24, 2009, “UNL” on November 18, 2009 and “BNO” on June 2, 2010, respectively. USCF is also the sponsor of the United States Commodity Index Fund (“USCI”), the United States Copper Index Fund (“CPER”), the United States Agriculture Index Fund (“USAG”) and the United States Metals Index Fund (“USMI”), each a series of the United States Commodity Index Funds Trust. USCI, CPER, USAG and USMI listed their units on the NYSE Arca under the ticker symbol “USCI” on August 10, 2010, “CPER” on November 15, 2011, “USAG” on April 13, 2012 and “USMI” on June 19, 2012, respectively. All funds listed previously are referred to collectively herein as the “Related Public Funds.” USCF has also filed registration statements to register units of the United States Sugar Fund (“USSF”), the United States Natural Gas Double Inverse Fund (“UNGD”), the United States Gasoil Fund (“USGO”) and the United States Asian Commodities Basket Fund (“UAC”), each a series of the United States Commodity Funds Trust I, and the US Golden Currency Fund (“HARD”), a series of the United States Currency Funds Trust. USSF, UNGD, USGO and HARD are currently not available to the public, as such funds are still in the process of review by various regulatory agencies which have regulatory authority over USCF and such funds. UAC has been declared effective by the regulatory agencies which have regulatory authority over USCF and UAC, but at the time of the filing of this quarterly report on Form 10-Q, UAC has not been made available to the public.

Effective February 29, 2012, US12OF issues units to certain authorized purchasers (“Authorized Purchasers”) by offering baskets consisting of 50,000 units (“Creation Baskets”) through ALPS Distributors, Inc., as the marketing agent (the “Marketing Agent”). Prior to February 29, 2012, US12OF issued units to Authorized Purchasers by offering baskets consisting of 100,000 units through the Marketing Agent. The purchase price for a Creation Basket is based upon the NAV of a unit 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.

From July 1, 2011 through December 31, 2013 (and continuing at least through May 1, 2014), the applicable transaction fee paid by Authorized Purchasers is $350 to US12OF for each order they place to create or redeem one or more baskets (“Redemption Baskets”); prior to July 1, 2011, this fee was $1,000. Units may be purchased or sold on a nationally recognized securities exchange in smaller increments than a Creation Basket or Redemption Basket. Units purchased or sold on a nationally recognized securities exchange are not purchased or sold at the per unit NAV of US12OF but rather at market prices quoted on such exchange.

On December 4, 2007, US12OF initially registered 11,000,000 units on Form S-1 with the U.S. Securities and Exchange Commission (the “SEC”). On December 6, 2007, US12OF listed its units on the AMEX under the ticker symbol “USL”. On that day, US12OF established its initial per unit NAV by setting the price at $50.00 and issued 300,000 units in exchange for $15,000,000. US12OF also commenced investment operations on December 6, 2007, by purchasing Oil Futures Contracts traded on the NYMEX based on light, sweet crude oil. As of June 30, 2013, US12OF had registered a total of 100,000,000 units.

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 (“GAAP”) in the United States of America. The financial information included herein is unaudited; however, such financial information reflects all adjustments, consisting only of normal recurring adjustments, which are, in the opinion of USCF, necessary for the fair presentation of the condensed financial statements for the interim period.

NOTE 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

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. US12OF earns interest on its assets denominated in U.S. dollars on deposit with the futures commission merchant at the 90-day Treasury bill rate. In addition, US12OF earns income on funds held at the custodian or futures commission merchant 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.

8

Income Taxes

US12OF 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 GAAP, US12OF 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. US12OF files an income tax return in the U.S. federal jurisdiction, and may file income tax returns in various U.S. states. US12OF is not subject to income tax return examinations by major taxing authorities for years before 2009. 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 US12OF recording a tax liability that reduces net assets. However, US12OF’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. US12OF 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, 2013.

Creations and Redemptions

Effective February 29, 2012, Authorized Purchasers may purchase Creation Baskets or redeem Redemption Baskets only in blocks of 50,000 units at a price equal to the NAV of the units calculated shortly after the close of the core trading session on the NYSE Arca on the day the order is placed. Prior to February 29, 2012, Authorized Purchasers could only purchase Creation Baskets or redeem Redemption Baskets in blocks of 100,000 units.

US12OF receives or pays the proceeds from units sold or redeemed within three business days after the trade date of the purchase or redemption. The amounts due from Authorized Purchasers are reflected in US12OF’s condensed statements of financial condition as receivable for units sold, and amounts payable to Authorized Purchasers upon redemption are reflected as payable for units redeemed.

Partnership Capital and Allocation of Partnership Income and Losses

Profit or loss shall be allocated among the partners of US12OF in proportion to the number of units 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 Unit Net Asset Value

US12OF’s per unit 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 units outstanding. US12OF 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 Unit

Net income (loss) per unit is the difference between the per unit NAV at the beginning of each period and at the end of each period. The weighted average number of units outstanding was computed for purposes of disclosing net income (loss) per weighted average unit. The weighted average units are equal to the number of units outstanding at the end of the period, adjusted proportionately for units added and redeemed based on the amount of time the units were outstanding during such period. There were no units held by USCF at June 30, 2013.

9

Offering Costs

Offering costs incurred in connection with the registration of additional units after the initial registration of units are borne by US12OF. These costs include registration fees paid to regulatory agencies and all legal, accounting, printing and other expenses associated with such offerings. These costs are accounted for as a deferred charge and thereafter amortized to expense over twelve months on a straight-line basis or a shorter period if warranted.

Cash Equivalents

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

Reclassification

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

Use of Estimates

The preparation of condensed financial statements in conformity with 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.

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 US12OF in accordance with the objectives and policies of US12OF. In addition, USCF has arranged for one or more third parties to provide administrative, custody, accounting, transfer agency and other necessary services to US12OF. For these services, US12OF is contractually obligated to pay USCF a fee, which is paid monthly, equal to 0.60% per annum of average daily total net assets.

Ongoing Registration Fees and Other Offering Expenses

US12OF pays all costs and expenses associated with the ongoing registration of its units subsequent to the initial offering. These costs include registration or other fees paid to regulatory agencies in connection with the offer and sale of units, and all legal, accounting, printing and other expenses associated with such offer and sale. For the six months ended June 30, 2013 and 2012, US12OF incurred $59,049 and $4,732, respectively, in registration fees and other offering expenses.

Directors’ Fees and Expenses

US12OF is responsible for paying its portion of the directors’ and officers’ liability insurance for US12OF and the Related Public Funds and the fees and expenses of the independent directors who also serve as audit committee members of US12OF and the Related Public Funds organized as limited partnerships and, as of July 8, 2011, the Related Public Funds organized as a series of a Delaware statutory trust. US12OF 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 fund computed on a daily basis. These fees and expenses for the year ending December 31, 2013 are estimated to be a total of $560,625 for US12OF and the Related Public Funds.

10

Licensing Fees

As discussed in Note 4 below, US12OF entered into a licensing agreement with the NYMEX on April 10, 2006, as amended on October 20, 2011. Pursuant to the agreement, through October 19, 2011, US12OF and the Related Public Funds, other than USBO, USCI, CPER, USAG and USMI, paid a licensing fee that was equal to 0.04% for the first $1,000,000,000 of combined net assets of the funds and 0.02% for combined net assets above $1,000,000,000. On and after October 20, 2011, US12OF and the Related Public Funds, other than USBO, USCI, CPER, USAG and USMI, pay a licensing fee that is equal to 0.015% on all net assets. During the six months ended June 30, 2013 and 2012, US12OF incurred $7,084 and $11,577, respectively, under this arrangement.

Investor Tax Reporting Cost

The fees and expenses associated with US12OF’s audit expenses and tax accounting and reporting requirements are paid by US12OF. These costs are estimated to be $200,000 for the year ending December 31, 2013.

Other Expenses and Fees

In addition to the fees described above, US12OF pays all brokerage fees and other expenses in connection with the operation of US12OF, excluding costs and expenses paid by USCF as outlined in Note 4 below.

NOTE 4 — CONTRACTS AND AGREEMENTS

US12OF is party to a marketing agent agreement, dated as of November 13, 2007, as amended from time to time, with the Marketing Agent and USCF, whereby the Marketing Agent provides certain marketing services for US12OF as outlined in the agreement. The fee of the Marketing Agent, which is borne by USCF, is equal to 0.06% on US12OF’s assets up to $3 billion and 0.04% on US12OF’s assets in excess of $3 billion. 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 US12OF’s offering.

The above fee does not include the following expenses, which are also borne by USCF: the cost of placing advertisements in various periodicals; website construction and development; or the printing and production of various marketing materials.

US12OF is also party to a custodian agreement, dated October 5, 2007, as amended from time to time, with Brown Brothers Harriman & Co. (“BBH&Co.”) and USCF, whereby BBH&Co. holds investments on behalf of US12OF. USCF pays the fees of the custodian, which are determined by the parties from time to time. In addition, US12OF is party to an administrative agency agreement, dated October 5, 2007, as amended from time to time, with USCF and BBH&Co., whereby BBH&Co. acts as the administrative agent, transfer agent and registrar for US12OF. USCF also pays the fees of BBH&Co. for its services under such agreement and such fees are determined by the parties from time to time.

Currently, USCF pays BBH&Co. for its services, in the foregoing capacities, a minimum amount of $75,000 annually for its custody, fund accounting and fund administration services rendered to US12OF and each of the Related Public Funds, as well as a $20,000 annual fee for its transfer agency services. In addition, USCF pays BBH&Co. an asset-based charge of (a) 0.06% for the first $500 million of US12OF’s, USOF’s, USNG’s, UGA’s, USDHO’s, USSO’s, US12NG’s, USBO’s, USCI’s, CPER’s, USAG’s and USMI’s combined net assets, (b) 0.0465% for US12OF’s, USOF’s, USNG’s, UGA’s, USDHO’s, USSO’s, US12NG’s, USBO’s, USCI’s, CPER’s, USAG’s and USMI’s combined net assets greater than $500 million but less than $1 billion, and (c) 0.035% once US12OF’s, USOF’s, USNG’s, UGA’s, USDHO’s, USSO’s, US12NG’s, USBO’s, USCI’s, CPER’s, USAG’s and USMI’s combined net assets exceed $1 billion. The annual minimum amount will not apply if the asset-based charge for all accounts in the aggregate exceeds $75,000. USCF also pays transaction fees ranging from $7 to $15 per transaction.

11

US12OF has entered into a brokerage agreement with UBS Securities LLC (“UBS Securities”). The agreement requires UBS Securities to provide services to US12OF 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 UBS Securities for US12OF’s account. In accordance with the agreement, UBS Securities charges US12OF commissions of approximately $7 to $15 per round-turn trade, including applicable exchange 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 US12OF issues units as a result of a Creation Basket, as well as fees incurred when selling Oil Futures Contracts and options on Oil Futures Contracts when US12OF redeems units 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. US12OF 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”). During the six months ended June 30, 2013, total commissions accrued to brokers amounted to $6,271. Of this amount, approximately $2,449 was a result of rebalancing costs and approximately $3,822 was the result of trades necessitated by creation and redemption activity. By comparison, during the six months ended June 30, 2012, total commissions accrued to brokers amounted to $11,344. Of this amount, approximately $3,587 was a result of rebalancing costs and approximately $7,757 was the result of trades necessitated by creation and redemption activity. The decrease in the total commissions accrued to brokers for the six months ended June 30, 2013, as compared to the six months ended June 30, 2012, was primarily a function of decreased brokerage fees due to a lower number of futures contracts being held and traded as a result of the decrease in US12OF’s total net assets during the six months ended June 30, 2013. The decrease in total net assets required US12OF to purchase a fewer number of Oil Futures Contracts and incur a lower amount of broker commissions during the six months ended June 30, 2013. As an annualized percentage of average daily total net assets, the figure for the six months ended June 30, 2013 represents approximately 0.01% of average daily total net assets. By comparison, the figure for the six months ended June 30, 2012 represented approximately 0.01% of average daily total net assets. However, there can be no assurance that commission costs and portfolio turnover will not cause commission expenses to rise in future quarters.

US12OF and the NYMEX entered into a licensing agreement on April 10, 2006, as amended on October 20, 2011, whereby US12OF was granted a non-exclusive license to use certain of the NYMEX’s settlement prices and service marks. Under the licensing agreement, US12OF and the Related Public Funds, other than USBO, USCI, CPER, USAG and USMI, pay the NYMEX an asset-based fee for the license, the terms of which are described in Note 3. US12OF expressly disclaims any association with the NYMEX or endorsement of US12OF 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

US12OF engages in the trading of futures contracts, options on futures contracts and cleared swaps (collectively, “derivatives”). US12OF 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. US12OF may enter into futures contracts and options on futures contracts 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.

The purchase and sale of futures contracts, options on futures contracts and cleared swaps require margin deposits with a futures commission merchant. Additional deposits may be necessary for any loss on contract value. The Commodity Exchange Act requires a futures commission merchant to segregate all customer transactions and assets from the futures commission merchant’s proprietary activities.

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 US12OF 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.

12

All of the futures contracts held by US12OF were exchange-traded through June 30, 2013. The risks associated with exchange-traded contracts are generally perceived to be less than those associated with over-the-counter transactions since, in over-the-counter transactions, a party must rely solely on the credit of its respective individual counterparties. However, in the future, if US12OF 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. US12OF 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, US12OF bears the risk of financial failure by the clearing broker.

US12OF’s cash and other property, such as Treasuries, deposited with a futures commission merchant are considered commingled with all other customer funds, subject to the futures commission merchant’s segregation requirements. In the event of a futures commission merchant’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 a futures commission merchant could result in the complete loss of US12OF’s assets posted with that futures commission merchant; however, the majority of US12OF’s assets are held in Treasuries, cash and/or cash equivalents with US12OF’s custodian and would not be impacted by the insolvency of a futures commission merchant. The failure or insolvency of US12OF’s custodian, however, could result in a substantial loss of US12OF’s assets.

USCF invests a portion of US12OF’s cash in money market funds that seek to maintain a stable per unit NAV. US12OF is exposed to any risk of loss associated with an investment in such money market funds. As of June 30, 2013 and December 31, 2012, US12OF held investments in money market funds in the amounts of $62,156,064 and $86,156,064, respectively. US12OF 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 June 30, 2013 and December 31, 2012, US12OF held cash deposits and investments in Treasuries in the amounts of $9,734,601 and $12,085,820, respectively, with the custodian and futures commission merchant. Some or all of these amounts may be subject to loss should US12OF’s custodian and/or futures commission merchant cease operations.

For derivatives, risks arise from changes in the market value of the contracts. Theoretically, US12OF 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, US12OF 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.

US12OF’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, US12OF 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 US12OF 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.

NOTE 6 — FINANCIAL HIGHLIGHTS

The following table presents per unit performance data and other supplemental financial data for the six months ended June 30, 2013 and 2012 for the unitholders. This information has been derived from information presented in the condensed financial statements.

Total returns are calculated based on the change in value during the period. An individual unitholder’s total return and ratio may vary from the above total returns and ratios based on the timing of contributions to and withdrawals from US12OF.

NOTE 7 — FAIR VALUE OF FINANCIAL INSTRUMENTS

US12OF 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 US12OF (observable inputs) and (2) US12OF’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.

14

The following table summarizes the valuation of US12OF’s securities at June 30, 2013 using the fair value hierarchy:

At June 30, 2013 |  | Total |  |  | Level I |  |  | Level II |  |  | Level III |
Short-Term Investments |  | $ | 66,155,111 |  |  | $ | 66,155,111 |  |  | $ | — |  |  | $ | — |

United States Contracts |  |  | 445,310 |  |  |  | 445,310 |  |  |  | — |  |  |  | — |

During the six months ended June 30, 2013, there were no transfers between Level I and Level II.

The following table summarizes the valuation of US12OF’s securities at December 31, 2012 using the fair value hierarchy:

At December 31, 2012 |  | Total |  |  | Level I |  |  | Level II |  |  | Level III |

| Item 2. | Management’s Discussion and Analysis of Financial Condition and Results of Operations.

The following discussion should be read in conjunction with the condensed financial statements and the notes thereto of the United States 12 Month Oil Fund, LP (“US12OF”) included elsewhere in this quarterly report on Form 10-Q.

Forward-Looking Information

This quarterly report on Form 10-Q, including this “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” contains forward-looking statements regarding the plans and objectives of management for future operations. This information may involve known and unknown risks, uncertainties and other factors that may cause US12OF’s actual results, performance or achievements to be materially different from future results, performance or achievements expressed or implied by any forward-looking statements. Forward-looking statements, which involve assumptions and describe US12OF’s future plans, strategies and expectations, are generally identifiable by use of the words “may,” “will,” “should,” “expect,” “anticipate,” “estimate,” “believe,” “intend” or “project,” the negative of these words, other variations on these words or comparable terminology. These forward-looking statements are based on assumptions that may be incorrect, and US12OF cannot assure investors that the projections included in these forward-looking statements will come to pass. US12OF’s actual results could differ materially from those expressed or implied by the forward-looking statements as a result of various factors.

US12OF has based the forward-looking statements included in this quarterly report on Form 10-Q on information available to it on the date of this quarterly report on Form 10-Q, and US12OF assumes no obligation to update any such forward-looking statements. Although US12OF undertakes no obligation to revise or update any forward-looking statements, whether as a result of new information, future events or otherwise, investors are advised to consult any additional disclosures that US12OF may make directly to them or through reports that US12OF in the future files with the U.S. Securities and Exchange Commission (the “SEC”), including annual reports on Form 10-K, quarterly reports on Form 10-Q and current reports on Form 8-K.

Introduction

US12OF, a Delaware limited partnership, is a commodity pool that issues units that may be purchased and sold on the NYSE Arca, Inc. (the “NYSE Arca”). The investment objective of US12OF is for the daily changes in percentage terms of its units’ per unit 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 average of the prices of 12 futures contracts for light, sweet crude oil traded on the New York Mercantile Exchange (the “NYMEX”) that is the near month contract to expire and the contracts for the following 11 months for a total of 12 consecutive months’ contracts, 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 and the contracts for the following 11 consecutive months (the “Benchmark Futures Contracts”), less US12OF’s expenses. “Near month contract” means the next contract traded on the NYMEX due to expire. “Next month contract” means the first contract traded on the NYMEX due to expire after the near month contract. When calculating the daily movement of the average price of the 12 contracts, each contract month will be equally weighted. It is not the intent of US12OF to be operated in a fashion such that the per unit NAV will equal, in dollar terms, the spot price of light, sweet crude oil or any particular futures contract based on light, sweet crude oil. It is not the intent of US12OF to be operated in a fashion such that its per unit NAV will reflect the percentage change of the price of any particular futures contract as measured over a time period greater than one day. The general partner of US12OF, United States Commodity Funds LLC (“USCF”), believes that it is not practical to manage the portfolio to achieve such an investment goal when investing in Oil Futures Contracts (as defined below) and Other Oil-Related Investments (as defined below).

US12OF invests in futures contracts for light, sweet crude oil, other types of crude oil, 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 interests such as cash-settled options on Oil Futures Contracts, forward contracts for oil, cleared swap contracts and over-the-counter transactions that are based on the price of crude oil, other petroleum-based fuels, Oil Futures Contracts and indices based on the foregoing (collectively, “Other Oil-Related Investments”). For convenience and unless otherwise specified, Oil Futures Contracts and Other Oil-Related Investments collectively are referred to as “Oil Interests” in this quarterly report on Form 10-Q.

US12OF seeks to achieve its investment objective by investing in a combination of Oil Futures Contracts and Other Oil-Related Investments such that daily changes in its per unit NAV, measured in percentage terms, will closely track the daily changes in the average of the prices of the Benchmark Oil Futures Contracts, also measured in percentage terms. USCF believes the daily changes in the average of the prices of the Benchmark Oil Futures Contracts have historically exhibited a close correlation with the daily changes in the spot price of light, sweet crude oil. It is not the intent of US12OF to be operated in a fashion such that the per unit NAV will equal, in dollar terms, the spot price of light, sweet crude oil or any particular futures contract based on light, sweet crude oil. It is not the intent of US12OF to be operated in a fashion such that its per unit NAV will reflect the percentage change of the price of any particular futures contract as measured over a time period greater than one day. USCF believes that it is not practical to manage the portfolio to achieve such an investment goal when investing in Oil Futures Contracts and Other Oil-Related Investments.

Regulatory Disclosure

Impact of Accountability Levels, Position Limits and Price Fluctuation Limits. Futures contracts include typical and significant characteristics. Most significantly, the Commodity Futures Trading Commission (the “CFTC”) and the futures exchanges have established accountability levels and position limits on the maximum net long or net short futures contracts in commodity interests that any person or group of persons under common trading control (other than as a hedge, which an investment by US12OF is not) may hold, own or control. The net position is the difference between an individual’s or firm’s open long contracts and open short contracts in any one commodity. In addition, most U.S.-based futures exchanges, such as the NYMEX, limit the daily price fluctuation for futures contracts. Currently, the ICE Futures imposes position and accountability limits that are similar to those imposed by U.S.-based futures exchanges and also limits the maximum daily price fluctuation, while some other non-U.S. futures exchanges have not adopted such limits.

The accountability levels for the Benchmark Futures Contracts and other Oil Futures Contracts traded on U.S.-based futures exchanges, such as the NYMEX, are not a fixed ceiling, but rather a threshold above which the NYMEX may exercise greater scrutiny and control over an investor’s positions. The current accountability level for investments for any one month in the Benchmark Futures Contracts is 10,000 contracts. In addition, the NYMEX imposes an accountability level for all months of 20,000 net futures contracts for light, sweet crude oil. In addition, ICE Futures maintains accountability levels, position limits and monitoring authority for its futures contracts for light, sweet crude oil. If US12OF and the Related Public Funds (as defined below) exceed these accountability levels for investments in the futures contract for light, sweet crude oil, the NYMEX and ICE Futures will monitor such exposure and may ask for further information on their activities including the total size of all positions, investment and trading strategy, and the extent of liquidity resources of US12OF and the Related Public Funds. If deemed necessary by the NYMEX and/or ICE Futures, US12OF could be ordered to reduce its position back to the accountability level. As of June 30, 2013, US12OF held 772 futures contracts for light, sweet crude oil traded on the NYMEX and did not hold any Oil Futures Contracts traded on the ICE Futures. For the six months ended June 30, 2013, US12OF did not exceed accountability levels imposed by the NYMEX or ICE Futures.

Position limits differ from accountability levels in that they represent fixed limits on the maximum number of futures contracts that any person may hold and cannot allow such limits to be exceeded without express CFTC authority to do so. In addition to accountability levels and position limits that may apply at any time, the NYMEX and the ICE Futures impose position limits on contracts held in the last few days of trading in the near month contract to expire. It is unlikely that US12OF will run up against such position limits because US12OF’s investment strategy is to close out its positions and “roll” from the near month contract to expire and the eleven following months to the next month contract to expire and the eleven following months during one day each month. For the six months ended June 30, 2013, US12OF did not exceed any position limits imposed by the NYMEX and ICE Futures.

The regulation of commodity interest trading in the United States and other countries is an evolving area of the law, as exemplified by the various discussions of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”). The various statements made in this summary are subject to modification by legislative action and changes in the rules and regulations of the CFTC, the National Futures Association (the “NFA”), the futures exchanges, clearing organizations and other regulatory bodies. Pending final resolution of all applicable regulatory requirements, some specific examples of how the new Dodd-Frank Act provisions and rules adopted thereunder could impact US12OF are discussed below.

Futures Contracts and Position Limits

The CFTC is prohibited by statute from regulating trading on non-U.S. futures exchanges and markets. The CFTC, however, has adopted regulations relating to the marketing of non-U.S. futures contracts in the United States. These regulations permit certain contracts on non-U.S. exchanges to be offered and sold in the United States.

In October 2011, the CFTC adopted rules that impose new position limits on Referenced Contracts (as defined below) involving 28 energy, metals and agricultural commodities (the “Position Limit Rules”). The Position Limit Rules were scheduled to become effective on October 12, 2012. However, on September 28, 2012, the United States District Court for the District of Columbia vacated these regulations on the basis of ambiguities in the provisions of the Commodity Exchange Act (“CEA”) (as modified by the Dodd-Frank Act) upon which the regulations were based. In its September 28, 2012 decision, the court remanded the Position Limit Rules to the CFTC with instructions to use its expertise and experience to resolve the ambiguities in the statute. On November 15, 2012, the CFTC indicated that it will move forward with an appeal of the District Court’s decision to vacate the Position Limit Rules. At this time, it is not possible to predict how the CFTC’s appeal could affect US12OF, but it may be substantial and adverse. Furthermore, until such time as the appeal is resolved or, if applicable revisions to the Position Limit Rules are proposed and adopted, the regulatory architecture in effect prior to the enactment of the Position Limit Rules will govern transactions in commodities and related derivatives (collectively, “Referenced Contracts”). Under that system, the CFTC enforces federal limits on speculation in agricultural products (e.g., corn, wheat and soy), while futures exchanges enforce position limits and accountability levels for agricultural and certain energy products (e.g., oil and natural gas). As a result, US12OF may be limited with respect to the size of its investments in any commodities subject to these limits. Finally, subject to certain narrow exceptions, the vacated Position Limit Rules would have required the aggregation, for purposes of the position limits, of all positions in the 28 Referenced Contracts held by a single entity and its affiliates, regardless of whether such position existed on U.S. futures exchanges, non-U.S. futures exchanges, in cleared swaps or in over-the-counter swaps. The CFTC is presently considering new aggregation rules, under a rulemaking proposal that is distinct from the Position Limit Rules. At this time, it is unclear how any modified aggregation rules may affect US12OF, but it may be substantial and adverse. By way of example, the aggregation rules in combination with any potential revised Position Limit Rules may negatively impact the ability of US12OF to meet its investment objectives through limits that may inhibit USCF’s ability to sell additional Creation Baskets of US12OF.

Based on its current understanding of the final position limit regulations, USCF does not anticipate significant negative impact on the ability of US12OF to achieve its investment objective.

“Swap” Transactions

The Dodd-Frank Act imposes new regulatory requirements on certain “swap” transactions that US12OF is authorized to engage in that may ultimately impact the ability of US12OF to meet its investment objective. On August 13, 2012, the CFTC and the SEC published joint final rules defining the terms “swap” and “security-based swap.” The term “swap” is broadly defined to include various types of over-the-counter derivatives, including swaps and options. The effective date of these final rules was October 12, 2012.

The Dodd-Frank Act requires that certain transactions ultimately falling within the definition of “swap” be executed on organized exchanges or “swap execution facilities” and cleared through regulated clearing organizations (which are referred to in the Dodd-Frank Act as “derivative clearing organizations” (“DCOs”)), if the CFTC mandates the central clearing of a particular contract. On November 28, 2012, the CFTC issued its final clearing determination requiring that certain credit default swaps and interest rate swaps be cleared by registered DCOs. This is the CFTC’s first clearing determination under the Dodd-Frank Act and became effective on February 11, 2013. Beginning on March 11, 2013, “swap dealers,” “major swap participants” and certain active funds were required to clear certain credit default swaps and interest rate swaps; and beginning on June 10, 2013, commodity pools, certain private funds and entities predominantly engaged in financial activities were required to clear the same types of swaps. As a result, if US12OF enters into or has entered into certain interest rate and credit default swaps on or after June 10, 2013, such swaps will be required to be centrally cleared. Determination on other types of swaps are expected in the future, and, when finalized, could require US12OF to centrally clear certain over-the-counter instruments presently entered into and settled on a bi-lateral basis. If a swap is required to be cleared, the initial margin will be set by the clearing organization, subject to certain regulatory requirements and guidelines. Initial and variation margin requirements for swap dealers and major swap participants who enter into uncleared swaps and capital requirements for swap dealers and major swap participants who enter into both cleared and uncleared trades will be set by the CFTC, the SEC or the applicable Prudential Regulator.

18

On April 11, 2013, the CFTC published a final rule to exempt swaps between certain affiliated entities within a corporate group from the clearing requirement. The rule permits affiliated counterparties to elect not to clear a swap subject to the clearing requirement if, among other things, the counterparties are majority-owned affiliates whose financial statements are included in the same consolidated financial statements and whose swaps are documented and subject to a centralized risk management program. However, the exemption does not apply to swaps entered into by affiliated counterparties with unaffiliated counterparties.

On November 14, 2012, the CFTC proposed new regulations that would require enhanced customer protections, risk management programs, internal monitoring and controls, capital and liquidity standards, customer disclosures and auditing and examination programs for FCMs. The proposed rules are intended to afford greater assurances to market participants that customer segregated funds and secured amounts are protected, customers are provided with appropriate notice of the risks of futures trading and of the FCMs with which they may choose to do business, FCMs are monitoring and managing risks in a robust manner, the capital and liquidity of FCMs are strengthened to safeguard their continued operations and the auditing and examination programs of the CFTC and the self-regulatory organizations are monitoring the activities of FCMs in a thorough manner. The final regulations have not yet been adopted.

Additionally, the CFTC published rules on February 17, 2012 and April 3, 2012 that require “swap dealers” and “major swap participants” to: 1) adhere to business conduct standards, 2) implement policies and procedures to ensure compliance with the CEA and 3) maintain records of such compliance. These new requirements may impact the documentation requirements for both cleared and non-cleared swaps and cause swap dealers and major swap participants to face increased compliance costs that, in turn, may be passed along to counterparties (such as US12OF) in the form of higher fees and expenses that related to trading swaps. On July 27, 2013, the Division of Swap Dealer and Intermediary Oversight issued a time-limited no-action letter delaying the implementation of some of the documentation requirements placed on “swap dealers” and “major swap participants” for certain foreign-exchange forwards and swaps until September 1, 2013.

On April 5, 2013, the CFTC’s Division of Clearing and Risk issued a letter granting no-action relief from certain swap data reporting requirements for swaps entered into between affiliated counterparties. In general, the letter grants relief from, among others: real-time, historical and regular swap reporting (under Part 43, Part 45 and Part 46 of the CFTC’s regulations, respectively).

On April 9, 2013, the CFTC’s Division of Market Oversight issued a letter granting time-limited no-action relief to non-swap dealer, non-major swap participant counterparties from the real-time, regular and historical swap reporting requirements (under Part 43, Part 45 and Part 46 of the CFTC’s regulations, respectively). The regular reporting requirements (Part 45 of the CFTC regulations) for interest rate and credit swaps of a financial entity (including a commodity pool such as US12OF) began on April 10, 2013. The letter delays implementation of the reporting requirements based upon the asset class underlying the swap and the classification of the reporting counterparty. For a financial entity (including a commodity pool such as US12OF), regular reporting requirements for equity, foreign exchange and other commodity swaps (including swaps on oil) began on May 29, 2013 and reporting of all historical swaps for all asset classes begins on September 30, 2013.

The effect of the future regulatory change on US12OF is impossible to predict, but it could be substantial and adverse.

USCF, which is registered as a commodity pool operator (“CPO”) and as a swaps firm (pending) with the CFTC, is authorized by the Second Amended and Restated Agreement of Limited Partnership of US12OF (the “LP Agreement”) to manage US12OF. USCF is authorized by US12OF in its sole judgment to employ and establish the terms of employment for, and termination of, commodity trading advisors or FCMs.

Price Movements

Crude oil futures prices were volatile during the six months ended June 30, 2013 and exhibited moderate daily swings along with a slight upward trend during the period. The average price of the Benchmark Oil Futures Contracts started the period at $93.19 per barrel. Average prices hit a peak on February 12, 2013 at $98.51 per barrel. The low of the period was on April 17, 2013 when prices reached $86.46 per barrel. The period ended with the average price of the Benchmark Oil Futures Contracts at $93.41 per barrel, up approximately 0.24% over the period. US12OF’s per unit NAV started the period at $39.81 and ended the period at $40.07 on June 30, 2013, an increase of approximately 0.65% over the period. US12OF’s per unit NAV reached its high for the period on February 12, 2013 at $42.02 and reached its low for the period on April 17, 2013 at $36.90. The average Benchmark Oil Futures Contract prices listed above began with the February 2013 to January 2014 contracts and ended with the August 2013 to July 2014 contracts. The increase of approximately 0.24% on the average price of the Benchmark Oil Futures Contracts listed above is a hypothetical return only and could not actually be achieved by an investor holding Oil Futures Contracts. An investment in Oil Futures Contracts would need to be rolled forward during the time period described in order to simulate such a result. Furthermore, the change in the nominal price of these differing crude Oil Futures Contracts, measured from the start of the period to the end of the period, does not represent the actual benchmark results that US12OF seeks to track, which are more fully described below in the section titled “Tracking US12OF’s Benchmark.”

During the six months ended June 30, 2013, crude oil moved into a mild state of backwardation, meaning that the price of the near month crude Oil Futures Contract was greater than the price of the next month crude Oil Futures Contract, and contracts further away from expiration. Crude oil inventories, which reached historic levels in January 2009 and February 2009 and which appeared to be the primary cause of the steep level of contango, began to drop in March 2009 and continued to drop for the remainder of 2009 and the beginning of 2010. During the year ended December 31, 2011, crude oil inventories began to climb higher, which contributed to the crude oil futures market remaining in contango through the end of December 2011. During the six months ended June 30, 2013, crude oil inventories began to draw down from present levels which contributed to the crude oil futures market moving into backwardation through the end of June 2013. For a discussion of the impact of backwardation and contango on total returns, see “Term Structure of Crude Oil Prices and the Impact on Total Returns” below.

Valuation of Oil Futures Contracts and the Computation of the Per Unit NAV

The per unit NAV of US12OF’s units is calculated once each NYSE Arca trading day. The per unit NAV for a particular trading day is released after 4:00 p.m. New York time. Trading during the core trading session on the NYSE Arca typically closes at 4:00 p.m. New York time. US12OF’s administrator uses the NYMEX closing price (determined at the earlier of the close of the NYMEX or 2:30 p.m. New York time) for the contracts held on the NYMEX, but calculates or determines the value of all other US12OF investments, including ICE Futures contracts or other futures contracts, as of the earlier of the close of the NYSE Arca or 4:00 p.m. New York time.

Results of Operations and the Crude Oil Market

Results of Operations. On December 6, 2007, US12OF listed its units on the American Stock Exchange (the “AMEX”) under the ticker symbol “USL.” On that day, US12OF established its initial offering price at $50.00 per unit and issued 300,000 units to the initial authorized purchaser in exchange for $15,000,000 in cash. As a result of the acquisition of the AMEX by NYSE Euronext, US12OF’s units no longer trade on the AMEX and commenced trading on the NYSE Arca on November 25, 2008.

Since its initial offering of 11,000,000 units, US12OF has registered one subsequent offering of its units: 100,000,000 units which were registered with the SEC on March 31, 2009. Units offered by US12OF in the subsequent offerings were sold by it for cash at the units’ per unit NAV as described in the applicable prospectus. As of June 30, 2013, US12OF had issued 14,050,000 units, 1,800,000 of which were outstanding. As of June 30, 2013, there were 96,950,000 units registered but not yet issued.

20

More units may have been issued by US12OF than are outstanding due to the redemption of units. Unlike funds that are registered under the Investment Company Act of 1940, as amended, units that have been redeemed by US12OF cannot be resold by US12OF. As a result, US12OF contemplates that additional offerings of its units will be registered with the SEC in the future in anticipation of additional issuances and redemptions.

As of June 30, 2013, US12OF had the following authorized purchasers: Citadel Securities LLC, Citigroup Global Markets Inc., JP Morgan Securities Inc., Merrill Lynch Professional Clearing Corp., Morgan Stanley & Company Inc., NewEdge Group LLC, Nomura Securities International Inc., RBC Capital Markets Corporation, SG Americas Securities LLC and Virtu Financial Capital Markets.

For the Six Months Ended June 30, 2013 Compared to the Six Months Ended June 30, 2012

As of June 30, 2013, the total unrealized gain on Oil Futures Contracts owned or held on that day was $445,310 and US12OF established cash deposits and investments in short-term obligations of the United States of two years or less (“Treasuries”) and money market funds that were equal to $71,890,665. US12OF held 91.55% of its cash assets in overnight deposits and investments in money market funds at its custodian bank, while 8.45% of the cash balance was held as investments in Treasuries and margin deposits for the Oil Futures Contracts purchased at the FCM. The ending per unit NAV on June 30, 2013 was $40.07.

By comparison, as of June 30, 2012, the total unrealized loss on Oil Futures Contracts owned or held on that day was $8,462,260 and US12OF established cash deposits and investments in Treasuries and money market funds that were equal to $120,375,193. US12OF held 78.41% of its cash assets in overnight deposits and investments in money market funds at its custodian bank, while 21.59% of the cash balance was held as investments in Treasuries and margin deposits for the Oil Futures Contracts purchased at the FCM. The decrease in cash assets in overnight deposits and investments in Treasuries and money market funds for June 30, 2013, as compared to June 30, 2012, was the result of US12OF’s smaller size as measured by total net assets during the six months ended June 30, 2013. The ending per unit NAV on June 30, 2012 was $37.90. The increase in the per unit NAV for June 30, 2013, as compared to June 30, 2012, was primarily a result of higher prices for crude oil and the related increase in the value of the Oil Futures Contracts in which US12OF had invested between the period ended June 30, 2012 and the period ended June 30, 2013.

Portfolio Expenses. US12OF’s expenses consist of investment management fees, brokerage fees and commissions, certain offering costs, licensing fees, the fees and expenses of the independent directors of USCF and expenses relating to tax accounting and reporting requirements. The management fee that US12OF pays to USCF is calculated as a percentage of the total net assets of US12OF. US12OF pays USCF a management fee of 0.60% of its average daily total net assets. The fee is accrued daily and paid monthly.

During the six months ended June 30, 2013, the average daily total net assets of US12OF were $95,230,067. The management fee incurred by US12OF during the period amounted to $283,342. By comparison, during the six months ended June 30, 2012, the average daily total net assets of US12OF were $155,204,688. The management fee paid by US12OF during the period amounted to $463,070.

In addition to the management fee, US12OF pays all brokerage fees and other expenses, including tax reporting costs, licensing fees for the use of intellectual property, ongoing registration or other fees paid to the SEC, the Financial Industry Regulatory Authority (“FINRA”) and any other regulatory agency in connection with offers and sales of its units subsequent to the initial offering and all legal, accounting, printing and other expenses associated therewith. The total of these fees and expenses for the six months ended June 30, 2013 was $184,170, as compared to $117,943 for the six months ended June 30, 2012. The increase in total expenses excluding management fees for the six months ended June 30, 2013 as compared to the six months ended June 30, 2012, was primarily due to an increase in the amortization rate of registration expenses during the six months ended June 30, 2013. For the six months ended June 30, 2013, US12OF incurred $59,049 in ongoing registration fees and other expenses relating to the registration and offering of additional units. By comparison, for the six months ended June 30, 2012, US12OF incurred $4,732 in ongoing registration fees and other expenses relating to the registration and offering of additional units. The increase in registration fees and expenses incurred by US12OF for the six months ended June 30, 2013, as compared to the six months ended June 30, 2012, was due to a higher amortization rate of registration fees and expenses and increased audit and tax reporting expenses during the six months ended June 30, 2013.

21

US12OF is responsible for paying its portion of the directors’ and officers’ liability insurance of US12OF and the United States Oil Fund, LP, the United States Natural Gas Fund, LP, the United States Gasoline Fund, LP, the United States Diesel-Heating Oil Fund, LP (formerly, the United States Heating Oil Fund, LP), the United States Short Oil Fund, LP, the United States 12 Month Natural Gas Fund, LP, the United States Brent Oil Fund, LP, the United States Commodity Index Fund, the United States Copper Index Fund, the United States Agriculture Index Fund and the United States Metals Index Fund (collectively, the “Related Public Funds”) and the fees and expenses of the independent directors who also serve as audit committee members of US12OF and the Related Public Funds organized as limited partnerships and, as of July 8, 2011, the Related Public Funds organized as a series of a Delaware statutory trust. US12OF 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 fund computed on a daily basis. These fees and expenses for the year ending December 31, 2013 are estimated to be a total of $560,625 for US12OF and the Related Public Funds. By comparison, for the year ended December 31, 2012, these fees and expenses amounted to a total of $540,586 for US12OF and the Related Public Funds. US12OF’s portion of such fees and expenses for the year ended December 31, 2012 was $25,332.

US12OF also incurs commissions to brokers for the purchase and sale of Oil Futures Contracts, Other Oil-Related Investments or Treasuries. During the six months ended June 30, 2013, total commissions accrued to brokers amounted to $6,271. Of this amount, approximately $2,449 was a result of rebalancing costs and approximately $3,822 was the result of trades necessitated by creation and redemption activity. By comparison, during the six months ended June 30, 2012, total commissions accrued to brokers amounted to $11,344. Of this amount, approximately $3,587 was a result of rebalancing costs and approximately $7,757 was the result of trades necessitated by creation and redemption activity. The decrease in the total commissions accrued to brokers for the six months ended June 30, 2013, as compared to the six months ended June 30, 2012, was primarily a function of decreased brokerage fees due to a lower number of futures contracts being held and traded as a result of the decrease in US12OF’s total net assets during the six months ended June 30, 2013. The decrease in total net assets required US12OF to purchase a fewer number of Oil Futures Contracts and incur a lower amount of broker commissions during the six months ended June 30, 2013. As an annualized percentage of average daily total net assets, the figure for the six months ended June 30, 2013 represents approximately 0.01% of average daily total net assets. By comparison, the figure for the six months ended June 30, 2012 represented approximately 0.01% of average daily total net assets. However, there can be no assurance that commission costs and portfolio turnover will not cause commission expenses to rise in future quarters.

The fees and expenses associated with US12OF’s audit expenses and tax accounting and reporting requirements are paid by US12OF. These costs are estimated to be $200,000 for the year ending December 31, 2013.

Dividend and Interest Income. US12OF seeks to invest its assets such that it holds Oil Futures Contracts and Other Oil-Related Investments in an amount equal to the total net assets of its portfolio. Typically, such investments do not require US12OF to pay the full amount of the contract value at the time of purchase, but rather require US12OF to post an amount as a margin deposit against the eventual settlement of the contract. As a result, US12OF retains an amount that is approximately equal to its total net assets, which US12OF invests in Treasuries, cash and/or cash equivalents. This includes both the amount on deposit with the FCM as margin, as well as unrestricted cash and cash equivalents held with US12OF’s custodian bank. The Treasuries, cash and/or cash equivalents earn income that accrues on a daily basis. For the six months ended June 30, 2013, US12OF earned $14,243 in dividend and interest income on such Treasuries, cash and/or cash equivalents. Based on US12OF’s average daily total net assets, this was equivalent to an annualized yield of approximately 0.03%. US12OF purchased Treasuries during the six months ended June 30, 2013 and also held cash and/or cash equivalents during this time period. By comparison, for the six months ended June 30, 2012, US12OF earned $19,072 in dividend and interest income on such Treasuries, cash and/or cash equivalents. Based on US12OF’s average daily total net assets, this was equivalent to an annualized yield of approximately 0.02%. US12OF purchased Treasuries during the six months ended June 30, 2012 and also held cash and/or cash equivalents during this time period. Interest rates on short-term investments held by US12OF, including cash, cash equivalents and Treasuries, were higher during the six months ended June 30, 2013 compared to the six months ended June 30, 2012. As a result, the amount of income earned by US12OF as a percentage of average daily total net assets was higher during the six months ended June 30, 2013 as compared to the six months ended June 30, 2012.

22

For the Three Months Ended June 30, 2013 Compared to the Three Months Ended June 30, 2012

Portfolio Expenses. During the three months ended June 30, 2013, the average daily total net assets of US12OF were $86,614,883. The management fee incurred by US12OF during the period amounted to $129,566. By comparison, during the three months ended June 30, 2012, the average daily total net assets of US12OF were $138,881,021. The management fee paid by US12OF during the period amounted to $207,183.

In addition to the management fee, US12OF pays all brokerage fees and other expenses, including tax reporting costs, licensing fees for the use of intellectual property, ongoing registration or other fees paid to the SEC, FINRA and any other regulatory agency in connection with offers and sales of its units subsequent to the initial offering and all legal, accounting, printing and other expenses associated therewith. The total of these fees and expenses for the three months ended June 30, 2013 was $90,851, as compared to $58,114 for the three months ended June 30, 2012. The increase in total expenses excluding management fees for the three months ended June 30, 2013 as compared to the three months ended June 30, 2012, was primarily due to an increase in the amortization rate of registration expenses during the three months ended June 30, 2013. For the three months ended June 30, 2013, US12OF incurred $29,687 in ongoing registration fees and other expenses relating to the registration and offering of additional units. By comparison, for the three months ended June 30, 2012, US12OF incurred $2,366 in ongoing registration fees and other expenses relating to the registration and offering of additional units. The increase in registration fees and expenses incurred by US12OF for the three months ended June 30, 2013, as compared to the three months ended June 30, 2012, was primarily due to a higher amortization rate of registration fees and expenses during the three months ended June 30, 2013.

US12OF is responsible for paying its portion of the directors’ and officers’ liability insurance of US12OF and the Related Public Funds and the fees and expenses of the independent directors who also serve as audit committee members of US12OF and the Related Public Funds organized as limited partnerships and, as of July 8, 2011, the Related Public Funds organized as a series of a Delaware statutory trust. US12OF 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 fund computed on a daily basis. These fees and expenses for the year ending December 31, 2013 are estimated to be a total of $560,625 for US12OF and the Related Public Funds. By comparison, for the year ended December 31, 2012, these fees and expenses amounted to a total of $540,586 for US12OF and the Related Public Funds. US12OF’s portion of such fees and expenses for the year ended December 31, 2012 was $25,332.

US12OF also incurs commissions to brokers for the purchase and sale of Oil Futures Contracts, Other Oil-Related Investments or Treasuries. During the three months ended June 30, 2013, total commissions accrued to brokers amounted to $2,289. Of this amount, approximately $598 was a result of rebalancing costs and approximately $1,691 was the result of trades necessitated by creation and redemption activity. By comparison, during the three months ended June 30, 2012, total commissions accrued to brokers amounted to $6,454. Of this amount, approximately $879 was a result of rebalancing costs and approximately $5,575 was the result of trades necessitated by creation and redemption activity. The decrease in the total commissions accrued to brokers for the three months ended June 30, 2013, as compared to the three months ended June 30, 2012, was primarily a function of decreased brokerage fees due to a lower number of futures contracts being held and traded as a result of the decrease in US12OF’s total net assets during the three months ended June 30, 2013. The decrease in total net assets required US12OF to purchase a fewer number of Oil Futures Contracts and incur a lower amount of broker commissions during the three months ended June 30, 2013. As an annualized percentage of average daily total net assets, the figure for the three months ended June 30, 2013 represents approximately 0.01% of average daily total net assets. By comparison, the figure for the three months ended June 30, 2012 represented approximately 0.02% of average daily total net assets. However, there can be no assurance that commission costs and portfolio turnover will not cause commission expenses to rise in future quarters.

The fees and expenses associated with US12OF’s audit expenses and tax accounting and reporting requirements are paid by US12OF. These costs are estimated to be $200,000 for the year ending December 31, 2013.

Dividend and Interest Income. US12OF seeks to invest its assets such that it holds Oil Futures Contracts and Other Oil-Related Investments in an amount equal to the total net assets of its portfolio. Typically, such investments do not require US12OF to pay the full amount of the contract value at the time of purchase, but rather require US12OF to post an amount as a margin deposit against the eventual settlement of the contract. As a result, US12OF retains an amount that is approximately equal to its total net assets, which US12OF invests in Treasuries, cash and/or cash equivalents. This includes both the amount on deposit with the FCM as margin, as well as unrestricted cash and cash equivalents held with US12OF’s custodian bank. The Treasuries, cash and/or cash equivalents earn income that accrues on a daily basis. For the three months ended June 30, 2013, US12OF earned $6,436 in dividend and interest income on such Treasuries, cash and/or cash equivalents. Based on US12OF’s average daily total net assets, this was equivalent to an annualized yield of approximately 0.03%. US12OF purchased Treasuries during the three months ended June 30, 2013 and also held cash and/or cash equivalents during this time period. By comparison, for the three months ended June 30, 2012, US12OF earned $10,738 in dividend and interest income on such Treasuries, cash and/or cash equivalents. Based on US12OF’s average daily total net assets, this was equivalent to an annualized yield of approximately 0.03%. US12OF purchased Treasuries during the three months ended June 30, 2012 and also held cash and/or cash equivalents during this time period. Interest rates on short-term investments held by US12OF, including cash, cash equivalents and Treasuries, were lower during the three months ended June 30, 2013 compared to the three months ended June 30, 2012. As a result, the amount of income earned by US12OF as a percentage of average daily total net assets remained the same during the three months ended June 30, 2013 as compared to the three months ended June 30, 2012.

Tracking US12OF’s Benchmark

USCF seeks to manage US12OF’s portfolio such that changes in its average daily per unit NAV, on a percentage basis, closely track the daily changes in the average of the prices of the Benchmark Oil Futures Contracts, also on a percentage basis. Specifically, USCF seeks to manage the portfolio such that over any rolling period of 30 valuation days, the average daily change in US12OF’s per unit NAV is within a range of 90% to 110% (0.9 to 1.1) of the average daily change in the prices of the Benchmark Oil Futures Contracts. As an example, if the average daily movement of the average of the prices of the Benchmark Oil Futures Contracts for a particular 30-valuation day time period was 0.50% per day, USCF would attempt to manage the portfolio such that the average daily movement of the per unit NAV during that same time period fell between 0.45% and 0.55% (i.e., between 0.9 and 1.1 of the benchmark’s results). US12OF’s portfolio management goals do not include trying to make the nominal price of US12OF’s per unit NAV equal to the average of the nominal prices of the current Benchmark Oil Futures Contracts or the spot price for light, sweet crude oil. USCF believes that it is not practical to manage the portfolio to achieve such an investment goal when investing in listed Oil Futures Contracts.

For the 30 valuation days ended June 28, 2013, the simple average daily change in the Benchmark Oil Futures Contracts was (0.001)%, while the simple average daily change in the per unit NAV of US12OF over the same time period was (0.005)%. The average daily difference was (0.004)% (or (0.4) basis points, where 1 basis point equals 1/100 of 1%). As a percentage of the daily movement of the Benchmark Oil Futures Contracts, the average error in daily tracking by the per unit NAV was (2.516)%, meaning that over this time period US12OF’s tracking error was within the plus or minus 10% range established as its benchmark tracking goal. A significant portion of the level of US12OF’s relative tracking error as a percentage of the benchmark was due to periods of flat price returns. The first chart below shows the daily movement of US12OF’s per unit NAV versus the daily movement of the Benchmark Oil Futures Contracts for the 30-valuation day period ended June 28, 2013, the last day of trading in June. The second chart below shows the monthly total returns of US12OF as compared to the monthly value of the Benchmark Oil Futures Contracts since inception.

Since the commencement of the offering of US12OF units to the public on December 6, 2007 to June 30, 2013, the simple average daily change in the Benchmark Oil Futures Contracts was 0.008%, while the simple average daily change in the per unit NAV of US12OF over the same time period was 0.007%. The average daily difference was (0.002)% (or (0.2) basis points, where 1 basis point equals 1/100 of 1%). As a percentage of the daily movement of the Benchmark Oil Futures Contracts, the average error in daily tracking by the per unit NAV was (0.621)%, meaning that over this time period US12OF’s tracking error was within the plus or minus 10% range established as its benchmark tracking goal.

* PAST PERFORMANCE IS NOT NECESSARILY INDICATIVE OF FUTURE RESULTS

An alternative tracking measurement of the return performance of US12OF versus the return of its Benchmark Oil Futures Contracts can be calculated by comparing the actual return of US12OF, measured by changes in its per unit NAV, versus the expected changes in its per unit NAV under the assumption that US12OF’s returns had been exactly the same as the daily changes in its Benchmark Oil Futures Contracts.

For the six months ended June 30, 2013, the actual total return of US12OF as measured by changes in its per unit NAV was 0.65%. This is based on an initial per unit NAV of $39.81 as of December 31, 2012 and an ending per unit NAV as of June 30, 2013 of $40.07. During this time period, US12OF made no distributions to its unitholders. However, if US12OF’s daily changes in its per unit NAV had instead exactly tracked the changes in the daily total return of the Benchmark Oil Futures Contracts, US12OF would have had an estimated per unit NAV of $40.26 as of June 30, 2013, for a total return over the relevant time period of 1.13%. The difference between the actual per unit NAV total return of US12OF of 0.65% and the expected total return based on the Benchmark Oil Futures Contracts of 1.13% was an error over the time period of (0.48)%, which is to say that US12OF’s actual total return underperformed the benchmark result by that percentage. USCF believes that a portion of the difference between the actual total return and the expected benchmark total return can be attributed to the net impact of the expenses that US12OF pays, offset in part by the income that US12OF collects on its cash and cash equivalent holdings. During the six months ended June 30, 2013, US12OF earned dividend and interest income of $14,243, which is equivalent to a weighted average income rate of approximately 0.03% for such period. In addition, during the six months ended June 30, 2013, US12OF also collected $5,250 from its Authorized Purchasers for creating or redeeming baskets of units. This income also contributed to US12OF’s actual total return. During the six months ended June 30, 2013, US12OF incurred total expenses of $467,512. Income from dividends and interest and Authorized Purchaser collections net of expenses was $(448,019), which is equivalent to an annualized weighted average net income rate of approximately (0.95)% for the six months ended June 30, 2013. These expenses also contributed to US12OF’s actual return underperforming the benchmark results.

26

By comparison, for the six months ended June 30, 2012, the actual total return of US12OF as measured by changes in its per unit NAV was (12.79)%. This was based on an initial per unit NAV of $43.46 as of December 31, 2011 and an ending per unit NAV as of June 30, 2012 of $37.90. During this time period, US12OF made no distributions to its unitholders. However, if US12OF’s daily changes in its per unit NAV had instead exactly tracked the changes in the daily total return of the Benchmark Oil Futures Contracts, US12OF would have had an estimated per unit NAV of $38.04 as of June 30, 2012, for a total return over the relevant time period of (12.47)%. The difference between the actual per unit NAV total return of US12OF of (12.79)% and the expected total return based on the Benchmark Oil Futures Contracts of (12.47)% was an error over the time period of (0.32)%, which is to say that US12OF’s actual total return underperformed the benchmark result by that percentage. USCF believes that a portion of the difference between the actual total return and the expected benchmark total return can be attributed to the net impact of the expenses that US12OF paid, offset in part by the income that US12OF collected on its cash and cash equivalent holdings. During the six months ended June 30, 2012, US12OF earned dividend and interest income of $19,072, which was equivalent to a weighted average income rate of approximately 0.02% for such period. In addition, during the six months ended June 30, 2012, US12OF also collected $8,400 from its Authorized Purchasers for creating or redeeming baskets of units. This income also contributed to US12OF’s actual total return. During the six months ended June 30, 2012, US12OF incurred total expenses of $581,013. Income from dividends and interest and Authorized Purchaser collections net of expenses was $(553,541), which was equivalent to an annualized weighted average net income rate of approximately (0.72)% for the six months ended June 30, 2012. These expenses also contributed to US12OF’s actual return underperforming the benchmark results.

There are currently three factors that have impacted or are most likely to impact US12OF’s ability to accurately track its Benchmark Oil Futures Contracts.

First, US12OF may buy or sell its holdings in the then current Benchmark Oil Futures Contracts at a price other than the closing settlement price of that contract on the day during which US12OF executes the trade. In that case, US12OF may pay a price that is higher, or lower, than that of the Benchmark Oil Futures Contracts, which could cause the changes in the daily per unit NAV of US12OF to either be too high or too low relative to the daily changes in the Benchmark Oil Futures Contracts. During the six months ended June 30, 2013, USCF attempted to minimize the effect of these transactions by seeking to execute its purchase or sale of the Benchmark Oil Futures Contracts at, or as close as possible to, the end of the day settlement price. However, it may not always be possible for US12OF to obtain the closing settlement price and there is no assurance that failure to obtain the closing settlement price in the future will not adversely impact US12OF’s attempt to track the Benchmark Oil Futures Contracts over time.

Second, US12OF earns dividend and interest income on its cash, cash equivalents and Treasuries. US12OF is not required to distribute any portion of its income to its unitholders and did not make any distributions to unitholders during the six months ended June 30, 2013. Interest payments, and any other income, were retained within the portfolio and added to US12OF’s NAV. When this income exceeds the level of US12OF’s expenses for its management fee, brokerage commissions and other expenses (including ongoing registration fees, licensing fees and the fees and expenses of the independent directors of USCF), US12OF will realize a net yield that will tend to cause daily changes in the per unit NAV of US12OF to track slightly higher than daily changes in the average of the prices of the Benchmark Oil Futures Contracts. During the six months ended June 30, 2013, US12OF earned, on an annualized basis, approximately 0.03% on its cash and cash equivalent holdings. It also incurred cash expenses on an annualized basis of 0.60% for management fees, approximately 0.01% in brokerage commission costs related to the purchase and sale of futures contracts and approximately 0.38% for other expenses. The foregoing fees and expenses resulted in a net yield on an annualized basis of approximately (0.96)% and affected US12OF’s ability to track its benchmark. If short-term interest rates rise above the current levels, the level of deviation created by the yield would decrease. Conversely, if short-term interest rates were to decline, the amount of error created by the yield would increase. When short-term yields drop to a level lower than the combined expenses of the management fee and the brokerage commissions, then the tracking error becomes a negative number and would tend to cause the daily returns of the per unit NAV to underperform the daily returns of the Benchmark Oil Futures Contracts. USCF anticipates that interest rates will continue to remain at historical lows and, therefore, it is anticipated that fees and expenses paid by US12OF will continue to be higher than interest earned by US12OF. As such, USCF anticipates that US12OF will continue to underperform its benchmark until such a time when interest earned at least equals or exceeds the fees and expenses paid by US12OF.

27

Third, US12OF may hold Other Oil-Related Investments in its portfolio that may fail to closely track the Benchmark Oil Futures Contracts’ total return movements. In that case, the error in tracking the Benchmark Oil Futures Contracts could result in daily changes in the per unit NAV of US12OF that are either too high, or too low, relative to the daily changes in the Benchmark Oil Futures Contracts. During the six months ended June 30, 2013, US12OF did not hold any Other Oil-Related Investments. If US12OF increases in size, and due to its obligations to comply with regulatory limits, US12OF may invest in Other Oil-Related Investments which may have the effect of increasing transaction related expenses and may result in increased tracking error.

Term Structure of Crude Oil Futures Prices and the Impact on Total Returns. Several factors determine the total return from investing in a futures contract position. One factor that impacts the total return that will result from investing in near month futures contracts and “rolling” those contracts forward each month is the price relationship between the current near month contract and the next month contract. For example, if the price of the near month contract is higher than the next month contract (a situation referred to as “backwardation” in the futures market), then absent any other change there is a tendency for the price of a next month contract to rise in value as it becomes the near month contract and approaches expiration. Conversely, if the price of a near month contract is lower than the next month contract (a situation referred to as “contango” in the futures market), then absent any other change there is a tendency for the price of a next month contract to decline in value as it becomes the near month contract and approaches expiration.

As an example, assume that the price of crude oil for immediate delivery (the “spot” price), was $50 per barrel, and the value of a position in the near month futures contract was also $50. Over time, the price of the barrel of crude oil will fluctuate based on a number of market factors, including demand for oil relative to its supply. The value of the near month contract will likewise fluctuate in reaction to a number of market factors. If investors seek to maintain their position in a near month contract and not take delivery of the oil, every month they must sell their current near month contract as it approaches expiration and invest in the next month contract.

If the futures market is in backwardation, e.g., when the expected price of crude oil in the future would be less, the investor would be buying a next month contract for a lower price than the current near month contract. Using the $50 per barrel price above to represent the front month price, the price of the next month contract could be $49 per barrel, that is, 2% cheaper than the front month contract. Hypothetically, and assuming no other changes to either prevailing crude oil prices or the price relationship between the spot price, the near month contract and the next month contract (and ignoring the impact of commission costs and the income earned on cash and/or cash equivalents), the value of the $49 next month contract would rise as it approaches expiration and becomes the new near month contract with a price of $50. In this example, the value of an investment in the second month contract would tend to rise faster than the spot price of crude oil, or fall slower. As a result, it would be possible in this hypothetical example for the spot price of crude oil to have risen 10% after some period of time, while the value of the investment in the second month futures contract would have risen 12%, assuming backwardation is large enough or enough time has elapsed. Similarly, the spot price of crude oil could have fallen 10% while the value of an investment in the futures contract could have fallen only 8%. Over time, if backwardation remained constant, the difference would continue to increase.

If the futures market is in contango, the investor would be buying a next month contract for a higher price than the current near month contract. Using again the $50 per barrel price above to represent the front month price, the price of the next month contract could be $51 per barrel, that is, 2% more expensive than the front month contract. Hypothetically, and assuming no other changes to either prevailing crude oil prices or the price relationship between the spot price, the near month contract and the next month contract (and ignoring the impact of commission costs and the income earned on cash and/or cash equivalents), the value of the next month contract would fall as it approaches expiration and becomes the new near month contract with a price of $50. In this example, it would mean that the value of an investment in the second month would tend to rise slower than the spot price of crude oil, or fall faster. As a result, it would be possible in this hypothetical example for the spot price of crude oil to have risen 10% after some period of time, while the value of the investment in the second month futures contract will have risen only 8%, assuming contango is large enough or enough time has elapsed. Similarly, the spot price of crude oil could have fallen 10% while the value of an investment in the second month futures contract could have fallen 12%. Over time, if contango remained constant, the difference would continue to increase.

The chart below compares the price of the near month contract to the average price of the near 12 month contracts over the last 10 years for light, sweet crude oil. When the price of the near month contract is higher than the average price of the near 12 month contracts, the market would be described as being in backwardation. When the price of the near month contract is lower than the average price of the near 12 month contracts, the market would be described as being in contango. Although the prices of the near month contract and the average price of the near 12 month contracts do tend to move up or down together, it can be seen that at times the near month prices are clearly higher than the average price of the near 12 month contracts (backwardation), and other times they are below the average price of the near 12 month contracts (contango).

* PAST PERFORMANCE IS NOT NECESSARILY INDICATIVE OF FUTURE RESULTS

An alternative way to view the same data is to subtract the dollar price of the average dollar price of the near 12 month contracts for light, sweet crude oil from the dollar price of the near month contract for light, sweet crude oil. If the resulting number is a positive number, then the near month price is higher than the average price of the near 12 months and the market could be described as being in backwardation. If the resulting number is a negative number, then the near month price is lower than the average price of the near 12 months and the market could be described as being in contango. The chart below shows the results from subtracting the average dollar price of the near 12 month contracts from the near month price for the 10 year period between June 30, 2003 and June 30, 2013.

29

* PAST PERFORMANCE IS NOT NECESSARILY INDICATIVE OF FUTURE RESULTS

An investment in a portfolio that involved owning only the near month contract would likely produce a different result than an investment in a portfolio that owned an equal number of each of the near 12 months’ worth of contracts. Generally speaking, when the crude oil futures market is in backwardation, the near month only portfolio would tend to have a higher total return than the 12 month contract portfolio. Conversely, if the crude oil futures market was in contango, the portfolio containing 12 months’ worth of contracts would tend to outperform the near month only portfolio. The chart below shows the annual results of owning a portfolio consisting of the near month contract and a portfolio containing the near 12 months’ worth of contracts. In addition, the chart shows the annual change in the spot price of light, sweet crude oil. In this example, each month, the near month only portfolio would sell the near month contract at expiration and buy the next month out contract. The portfolio holding an equal number of the near 12 months’ worth of contracts would sell the near month contract at expiration and replace it with the contract that becomes the new twelfth month contract.

HYPOTHETICAL PERFORMANCE RESULTS HAVE MANY INHERENT LIMITATIONS, SOME OF WHICH ARE DESCRIBED BELOW. NO REPRESENTATION IS BEING MADE THAT US12OF WILL OR IS LIKELY TO ACHIEVE PROFITS OR LOSSES SIMILAR TO THOSE SHOWN. IN FACT, THERE ARE FREQUENTLY SHARP DIFFERENCES BETWEEN HYPOTHETICAL PERFORMANCE RESULTS AND THE ACTUAL RESULTS ACHIEVED BY ANY PARTICULAR TRADING PROGRAM.

ONE OF THE LIMITATIONS OF HYPOTHETICAL PERFORMANCE RESULTS IS THAT THEY ARE GENERALLY PREPARED WITH THE BENEFIT OF HINDSIGHT. IN ADDITION, HYPOTHETICAL TRADING DOES NOT INVOLVE FINANCIAL RISK, AND NO HYPOTHETICAL TRADING RECORD CAN COMPLETELY ACCOUNT FOR THE IMPACT OF FINANCIAL RISK IN ACTUAL TRADING.

FOR EXAMPLE, THE ABILITY TO WITHSTAND LOSSES OR TO ADHERE TO A PARTICULAR TRADING PROGRAM IN SPITE OF TRADING LOSSES ARE MATERIAL POINTS WHICH CAN ALSO ADVERSELY AFFECT ACTUAL TRADING RESULTS. THERE ARE NUMEROUS OTHER FACTORS RELATED TO THE MARKETS IN GENERAL OR TO THE IMPLEMENTATION OF ANY SPECIFIC TRADING PROGRAM WHICH CANNOT BE FULLY ACCOUNTED FOR IN THE PREPARATION OF HYPOTHETICAL PERFORMANCE RESULTS AND ALL OF WHICH CAN ADVERSELY AFFECT ACTUAL TRADING RESULTS.

As seen in the chart above, there have been periods of both positive and negative annual total returns for both hypothetical portfolios over the last 10 years. In addition, there have been periods during which the near month only approach had higher returns, and periods where the 12 month approach had higher total returns. The above chart does not represent the performance history of US12OF or any Related Public Fund.

Historically, the crude oil futures markets have experienced periods of contango and backwardation, with backwardation being in place more often than contango. During 2006 and the first half of 2007, these markets experienced contango. However, starting early in the third quarter of 2007, the crude oil futures market moved into backwardation. The crude oil markets remained in backwardation until late in the second quarter of 2008 when they moved into contango. The crude oil markets remained in contango until late in the third quarter of 2008, when the markets moved into backwardation. Early in the fourth quarter of 2008, the crude oil market moved back into contango and remained in contango for the balance of 2008. Throughout 2009, the crude oil market remained in contango. During parts of January and February 2009, the level of contango was unusually steep. Crude oil inventories, which reached historic levels in January and February 2009 and which appeared to be the primary cause of the steep level of contango, began to drop in March 2009 and continued to drop for the balance of 2009 and the beginning of 2010. The crude oil futures market remained in contango through 2010. In 2011, the crude oil futures market experienced long periods of mild contango, with the exception of a short period during the first quarter of 2011 where contango steepened by 4%. The 12 month strip for crude oil futures moved into backwardation on January 10, 2013 and remained in backwardation through the six months ended June 30, 2013.

USCF believes that holding futures contracts whose expiration dates are spread out over a 12 month period of time will cause the total return of such a portfolio to vary compared to a portfolio that holds only a single month’s contract (such as the near month contract). In particular, USCF believes that the total return of a portfolio holding contracts with a range of expiration months will be impacted differently by the price relationship between different contract months of the same commodity future compared to the total return of a portfolio consisting of the near month contract. USCF believes that based on historical evidence a portfolio that held futures contracts with a range of expiration dates spread out over a 12 month period of time would typically be impacted less by the positive effect of backwardation, and less by the negative effect of contango, compared to a portfolio that held contracts of a single near month. As a result, absent the impact of any other factors, a portfolio of 12 different monthly contracts would tend to have a lower total return than a near month only portfolio in a backwardation market and a higher total return in a contango market. However there can be no assurance that such historical relationships would provide the same or similar results in the future.

Periods of contango or backwardation do not materially impact US12OF’s investment objective of having the daily percentage changes in its per unit NAV track the daily percentage changes in the average of the prices of the Benchmark Oil Futures Contracts since the impact of backwardation and contango tend to equally impact the daily percentage changes in price of both US12OF’s units and the Benchmark Oil Futures Contracts. It is impossible to predict with any degree of certainty whether backwardation or contango will occur in the future. It is likely that both conditions will occur during different periods.

Crude Oil Market. During the six months ended June 30, 2013, crude oil prices were impacted by several factors. On the consumption side, demand moderated inside and outside the United States as global economic growth, including emerging economies such as China and India, showed signs of slowing economic growth. Europe in particular showed signs of weakness as the ongoing financial and banking crisis raised concerns during the first quarter of 2013. On the supply side, efforts to reduce production by the Organization of the Petroleum Exporting Countries (“OPEC”) to more closely match global consumption were partially successful. In the summer of 2011, production had been disrupted by political unrest in the Middle East, particularly Libya, which reduced global supply by approximately 1.8 million barrels per day. A partial resolution of the Libyan situation has reduced concerns regarding the global supply of crude oil. However, continuing concerns about the political standoff with Iran have left the market subject to bouts of heightened volatility as OPEC’s ability to replace Iranian oil currently subject to embargo is not unlimited. In recent years, oil production in the United States has increased, particularly in the Midwest. However, limits on oil transportation infrastructure, including pipelines, have made it more difficult for the increased production to move to the centers of refining, often leading to a build-up in crude oil inventory in the U.S. Midwest. The result is that crude oil prices in the middle of the United States, where the pricing point of the light, sweet crude oil contract is located, have tended to trade at a lower price than crude oil in other parts of the United States or globally. United States crude oil prices finished the second quarter of 2013 approximately 5.2% higher than at the beginning of the year, as the global economy continues to adjust to periods of slow recovery and economic growth. USCF believes that should the global economic situation cease to improve, or decline, there is a meaningful possibility that crude oil prices could further retreat from their current levels, while any military actions involving Iran would likely have the opposite effect.

Crude Oil Price Movements in Comparison to Other Energy Commodities and Investment Categories. USCF believes that investors frequently measure the degree to which prices or total returns of one investment or asset class move up or down in value in concert with another investment or asset class. Statistically, such a measure is usually done by measuring the correlation of the price movements of the two different investments or asset classes over some period of time. The correlation is scaled between 1 and -1, where 1 indicates that the two investment options move up or down in price or value together, known as “positive correlation,” and -1 indicates that they move in completely opposite directions, known as “negative correlation.” A correlation of 0 would mean that the movements of the two are neither positively nor negatively correlated, known as “non-correlation.” That is, the investment options sometimes move up and down together and other times move in opposite directions.

For the ten-year time period between June 30, 2003 and June 30, 2013, the table below compares the monthly movements of natural gas prices versus the monthly movements of the prices of several other energy commodities, such as crude oil, diesel-heating oil, and unleaded gasoline, as well as several major non-commodity investment asset classes, such as large cap U.S. equities, U.S. government bonds and global equities. It can be seen that over this particular time period, the movement of crude oil on a monthly basis was not strongly correlated, positively or negatively, with the movements of U.S. government bonds, global equities, large cap U.S. equities and natural gas. However, movements in crude oil had a strong positive correlation to movements in diesel-heating oil and unleaded gasoline.

PAST PERFORMANCE IS NOT NECESSARILY INDICATIVE OF FUTURE RESULTS

The table below covers a more recent, but much shorter, range of dates than the above table. Over the one-year period ended June 30, 2013, crude oil was not strongly correlated, positively or negatively, with the movements of U.S. government bonds, global equities, large cap U.S. equities and natural gas. However, movements in crude oil still had a strong positive correlation to the movements in diesel-heating oil and unleaded gasoline over the shorter time period. The correlation of crude oil with the movements of diesel-heating oil was stronger compared to what it had displayed over the ten-year period ended June 30, 2013. Unleaded gasoline still had a positive, yet weaker, correlation during the one-year period as compared to the ten-year period ended June 30, 2013. Crude oil and natural gas, which had been positively correlated over the ten-year period, were essentially weakly negatively correlated over the shorter time frame.

PAST PERFORMANCE IS NOT NECESSARILY INDICATIVE OF FUTURE RESULTS

Investors are cautioned that the historical price relationships between crude oil and various other energy commodities, as well as other investment asset classes, as measured by correlation may not be reliable predictors of future price movements and correlation results. The results pictured above would have been different if a different range of dates had been selected. USCF believes that crude oil has historically not demonstrated a strong correlation with equities or bonds over long periods of time. However, USCF also believes that in the future it is possible that crude oil could have long-term correlation results that indicate prices of crude oil more closely track the movements of equities or bonds. In addition, USCF believes that, when measured over time periods shorter than ten years, there will always be some periods where the correlation of crude oil to equities and bonds will be either more strongly positively correlated or more strongly negatively correlated than the long term historical results suggest.

The correlations between crude oil, natural gas, diesel-heating oil and gasoline are relevant because USCF endeavors to invest US12OF’s assets in Oil Futures Contracts and Other Oil-Related Investments so that daily changes in percentage terms in US12OF’s per unit NAV correlate as closely as possible with daily changes in percentage terms in the price of the Benchmark Oil Futures Contracts. If certain other fuel-based commodity futures contracts do not closely correlate with the Oil Futures Contracts, then their use could lead to greater tracking error. As noted above, USCF also believes that the changes in percentage terms in the price of the Benchmark Oil Futures Contracts will closely correlate with changes in percentage terms in the spot price of light, sweet crude oil.

Critical Accounting Policies

Preparation of the condensed financial statements and related disclosures in compliance with accounting principles generally accepted in the United States of America requires the application of appropriate accounting rules and guidance, as well as the use of estimates. US12OF’s application of these policies involves judgments and actual results may differ from the estimates used.

USCF has evaluated the nature and types of estimates that it makes in preparing US12OF’s condensed financial statements and related disclosures and has determined that the valuation of its investments, which are not traded on a United States or internationally recognized futures exchange (such as forward contracts and over-the-counter contracts) involves a critical accounting policy. The values which are used by US12OF for its Oil Futures Contracts are provided by its commodity broker who uses market prices when available, while over-the-counter contracts are valued based on the present value of estimated future cash flows that would be received from or paid to a third party in settlement of these derivative contracts prior to their delivery date and valued on a daily basis. In addition, US12OF estimates interest and dividend income on a daily basis using prevailing rates earned on its cash and cash equivalents. These estimates are adjusted to the actual amount received on a monthly basis and the difference, if any, is not considered material.

34

Liquidity and Capital Resources

US12OF has not made, and does not anticipate making, use of borrowings or other lines of credit to meet its obligations. US12OF has met, and it is anticipated that US12OF will continue to meet, its liquidity needs in the normal course of business from the proceeds of the sale of its investments, or from the Treasuries, cash and/or cash equivalents that it intends to hold at all times. US12OF’s liquidity needs include: redeeming units, providing margin deposits for its existing Oil Futures Contracts or the purchase of additional Oil Futures Contracts and posting collateral for its over-the-counter contracts, if applicable, and payment of its expenses, summarized below under “Contractual Obligations.”

US12OF currently generates cash primarily from: (i) the sale of baskets consisting of 50,000 units (“Creation Baskets”) and (ii) income earned on Treasuries, cash and/or cash equivalents. US12OF has allocated substantially all of its net assets to trading in Oil Interests. US12OF invests in Oil Interests to the fullest extent possible without being leveraged or unable to satisfy its current or potential margin or collateral obligations with respect to its investments in Oil Futures Contracts and Other Oil-Related Investments. A significant portion of US12OF’s NAV is held in cash and cash equivalents that are used as margin and as collateral for its trading in Oil Interests. The balance of the assets is held in US12OF’s account at its custodian bank. Income received from US12OF’s investments in money market funds and Treasuries is paid to US12OF. During the six months ended June 30, 2013, US12OF’s expenses exceeded the income US12OF earned and the cash earned from the sale of Creation Baskets and the redemption of Redemption Baskets. During the six months ended June 30, 2013, US12OF used other assets to pay expenses, which could cause a drop in US12OF’s NAV over time. To the extent expenses exceed income, US12OF’s NAV will be negatively impacted.

US12OF’s investments in Oil Interests may be subject to periods of illiquidity because of market conditions, regulatory considerations and other reasons. For example, most commodity exchanges limit the fluctuations in futures contracts prices during a single day by regulations referred to as “daily limits.” During a single day, no trades may be executed at prices beyond the daily limit. Once the price of a futures contract has increased or decreased by an amount equal to the daily limit, positions in the contracts can neither be taken nor liquidated unless the traders are willing to effect trades at or within the specified daily limit. Such market conditions could prevent US12OF from promptly liquidating its positions in Oil Futures Contracts. During the six months ended June 30, 2013, US12OF was not forced to purchase or liquidate any of its positions while daily limits were in effect; however, US12OF cannot predict whether such an event may occur in the future.

Prior to the initial offering of US12OF, all payments with respect to US12OF’s expenses were paid by USCF. US12OF does not have an obligation or intention to refund such payments by USCF. USCF is under no obligation to pay US12OF’s current or future expenses. Since the initial offering of units, US12OF has been responsible for expenses relating to: (i) management fees, (ii) brokerage fees and commissions, (iii) licensing fees for the use of intellectual property, (iv) ongoing registration expenses in connection with offers and sales of its units subsequent to the initial offering, (v) other expenses, including tax reporting costs, (vi) fees and expenses of the independent directors of USCF and (vii) other extraordinary expenses not in the ordinary course of business, while USCF has been responsible for expenses relating to the fees of US12OF’s Marketing Agent, Administrator and Custodian and registration expenses relating to the initial offering of units. If USCF and US12OF are unsuccessful in raising sufficient funds to cover these respective expenses or in locating any other source of funding, US12OF will terminate and investors may lose all or part of their investment.

Market Risk

Trading in Oil Futures Contracts and Other Oil-Related Investments, such as forwards, involves US12OF entering into contractual commitments to purchase or sell oil at a specified date in the future. The aggregate market value of the contracts will significantly exceed US12OF’s future cash requirements since US12OF intends to close out its open positions prior to settlement. As a result, US12OF is generally only subject to the risk of loss arising from the change in value of the contracts. US12OF considers the “fair value” of its derivative instruments to be the unrealized gain or loss on the contracts. The market risk associated with US12OF’s commitments to purchase oil is limited to the aggregate market value of the contracts held. However, should US12OF enter into a contractual commitment to sell oil, it would be required to make delivery of the oil at the contract price, repurchase the contract at prevailing prices or settle in cash. Since there are no limits on the future price of oil, the market risk to US12OF could be unlimited.

35

US12OF’s exposure to market risk depends on a number of factors, including the markets for oil, the volatility of interest rates and foreign exchange rates, the liquidity of the Oil Futures Contracts and Other Oil-Related Investments markets and the relationships among the contracts held by US12OF. Drastic market occurrences could ultimately lead to the loss of all or substantially all of an investor’s capital.

Credit Risk

When US12OF enters into Oil Futures Contracts and Other Oil-Related Investments, it is exposed to the credit risk that the counterparty will not be able to meet its obligations. The counterparty for the Oil Futures Contracts traded on the NYMEX and on most other futures exchanges is the clearinghouse associated with the particular exchange. In general, in addition to margin required to be posted by the clearinghouse in connection with cleared trades, clearinghouses are backed by their members who may be required to share in the financial burden resulting from the nonperformance of one of their members and, therefore, this additional member support should significantly reduce credit risk. Some foreign exchanges are not backed by their clearinghouse members but may be backed by a consortium of banks or other financial institutions. There can be no assurance that any counterparty, clearinghouse, or their members or their financial backers will satisfy their obligations to US12OF in such circumstances.

USCF attempts to manage the credit risk of US12OF by following various trading limitations and policies. In particular, US12OF generally posts margin and/or holds liquid assets that are approximately equal to the market value of its obligations to counterparties under the Oil Futures Contracts and Other Oil-Related Investments it holds. USCF has implemented procedures that include, but are not limited to, executing and clearing trades only with creditworthy parties and/or requiring the posting of collateral or margin by such parties for the benefit of US12OF to limit its credit exposure. UBS Securities LLC, US12OF’s commodity broker, or any other broker that may be retained by US12OF in the future, when acting as US12OF’s FCM in accepting orders to purchase or sell Oil Futures Contracts on United States exchanges, is required by CFTC regulations to separately account for and segregate as belonging to US12OF, all assets of US12OF relating to domestic Oil Futures Contracts trading. These FCMs are not allowed to commingle US12OF’s assets with their other assets. In addition, the CFTC requires commodity brokers to hold in a secure account US12OF’s assets related to foreign Oil Futures Contracts trading.

If, in the future, US12OF purchases over-the-counter contracts, see “Item 3. Quantitative and Qualitative Disclosures About Market Risk” in this quarterly report on Form 10-Q for a discussion of over-the-counter contracts.

As of June 30, 2013, US12OF held cash deposits and investments in Treasuries and money market funds in the amount of $71,890,665 with the custodian and FCM. Some or all of these amounts may be subject to loss should US12OF’s custodian and/or FCM cease operations.

Off Balance Sheet Financing

As of June 30, 2013, US12OF had no loan guarantee, credit support or other off-balance sheet arrangements of any kind other than agreements entered into in the normal course of business, which may include indemnification provisions relating to certain risks that service providers undertake in performing services which are in the best interests of US12OF. While US12OF’s exposure under these indemnification provisions cannot be estimated, they are not expected to have a material impact on US12OF’s financial position.

European Sovereign Debt

US12OF had no direct exposure to European sovereign debt as of June 30, 2013 and has no direct exposure to European sovereign debt as of the filing of this quarterly report on Form 10-Q.

36

Redemption Basket Obligation

In order to meet its investment objective and pay its contractual obligations described below, US12OF requires liquidity to redeem units, which redemptions must be in blocks of 50,000 units as of February 29, 2012 called “Redemption Baskets.” (Prior to February 29, 2012, the size of the Redemption Basket was 100,000 units). US12OF has to date satisfied this obligation by paying from the cash or cash equivalents it holds or through the sale of its Treasuries in an amount proportionate to the number of units being redeemed.

Contractual Obligations

US12OF’s primary contractual obligations are with USCF. In return for its services, USCF is entitled to a management fee calculated daily and paid monthly as a fixed percentage of US12OF’s NAV, currently 0.60% of NAV on its average daily total net assets.

USCF agreed to pay the start-up costs associated with the formation of US12OF, primarily its legal, accounting and other costs in connection with USCF’s registration with the CFTC as a CPO and the registration and listing of US12OF and its units with the SEC, FINRA and NYSE Arca (formerly, AMEX), respectively. However, since US12OF’s initial offering of units, offering costs incurred in connection with registering and listing additional units of US12OF have been directly borne on an ongoing basis by US12OF, and not by USCF.

USCF pays the fees of US12OF’s marketing agent, ALPS Distributors, Inc., and the fees of the custodian and transfer agent, Brown Brothers Harriman & Co. (“BBH&Co.”), as well as BBH&Co.’s fees for performing administrative services, including those in connection with the preparation of US12OF’s condensed financial statements and its SEC, NFA and CFTC reports. USCF and US12OF have also entered into a licensing agreement with the NYMEX pursuant to which US12OF and the Related Public Funds, other than USBO, USCI, CPER, USAG and USMI, pay a licensing fee to the NYMEX. US12OF also pays the fees and expenses associated with its tax accounting and reporting requirements.

In addition to USCF’s management fee, US12OF pays its brokerage fees (including fees to a FCM), over-the-counter dealer spreads, any licensing fees for the use of intellectual property, and, subsequent to the initial offering, registration and other fees paid to the SEC, FINRA, or other regulatory agencies in connection with the offer and sale of units, as well as legal, printing, accounting and other expenses associated therewith, and extraordinary expenses. The latter are expenses not incurred in the ordinary course of US12OF’s business, including expenses relating to the indemnification of any person against liabilities and obligations to the extent permitted by law and under the LP Agreement, the bringing or defending of actions in law or in equity or otherwise conducting litigation and incurring legal expenses and the settlement of claims and litigation. Commission payments to a FCM are on a contract-by-contract, or round turn, basis. US12OF also pays a portion of the fees and expenses of the independent directors of USCF. See Note 3 to the Notes to Condensed Financial Statements (Unaudited) in Item 1 of this quarterly report on Form 10-Q.

The parties cannot anticipate the amount of payments that will be required under these arrangements for future periods, as US12OF’s per unit NAVs and trading levels to meet its investment objective will not be known until a future date. These agreements are effective for a specific term agreed upon by the parties with an option to renew, or, in some cases, are in effect for the duration of US12OF’s existence. Either party may terminate these agreements earlier for certain reasons described in the agreements.

As of June 30, 2013, US12OF’s portfolio consisted of 772 WTI Crude Oil Futures CL Contracts traded on the NYMEX. As of June 30, 2013, US12OF did not hold any Oil Futures Contracts traded on the ICE Futures. For a list of US12OF’s current holdings, please see US12OF’s website at www.unitedstates12monthoilfund.com.

Item 3. | Quantitative and Qualitative Disclosures About Market Risk.

Over-the-Counter Derivatives (Including Spreads and Straddles)

In the future, US12OF may purchase over-the-counter contracts (“OTC Contracts”). Unlike most exchange-traded futures contracts or exchange-traded options on such futures, each party to an OTC Contract bears the credit risk that the other party may not be able to perform its obligations under its contract.

Swap transactions, like other financial transactions, involve a variety of significant risks. The specific risks presented by a particular swap transaction necessarily depend upon the terms and circumstances of the transaction. In general, however, all swap transactions involve some combination of market risk, credit risk, counterparty credit risk, funding risk, liquidity risk and operational risk.

Highly customized swap transactions in particular may increase liquidity risk, which may result in a suspension of redemptions. Highly leveraged transactions may experience substantial gains or losses in value as a result of relatively small changes in the value or level of an underlying or related market factor.

In evaluating the risks and contractual obligations associated with a particular swap transaction, it is important to consider that a swap transaction may be modified or terminated only by mutual consent of the original parties and subject to agreement on individually negotiated terms. Therefore, it may not be possible for USCF to modify, terminate or offset US12OF’s obligations or its exposure to the risks associated with a transaction prior to its scheduled termination date.

To reduce the credit risk that arises in connection with such contracts, US12OF will generally enter into an agreement with each counterparty based on the Master Agreement published by the International Swaps and Derivatives Association that provides for the netting of its overall exposure to its counterparty, if the counterparty is unable to meet its obligations to US12OF due to the occurrence of a specified event, such as the insolvency of the counterparty.

USCF assesses or reviews, as appropriate, the creditworthiness of each potential or existing counterparty to an OTC Contract pursuant to guidelines approved by USCF’s board of directors (the “Board”). Furthermore, USCF on behalf of US12OF only enters into OTC Contracts with counterparties who are, or are affiliates of, (a) banks regulated by a United States federal bank regulator, (b) broker-dealers regulated by the SEC, (c) insurance companies domiciled in the United States, or (d) producers, users or traders of energy, whether or not regulated by the CFTC. Any entity acting as a counterparty shall be regulated in either the United States or the United Kingdom unless otherwise approved by the Board after consultation with its legal counsel. Existing counterparties are also reviewed periodically by USCF. US12OF will also require that the counterparty be highly rated and/or provide collateral or other credit support. Even if collateral is used to reduce counterparty credit risk, sudden changes in the value of OTC transactions may leave a party open to financial risk due to a counterparty default since the collateral held may not cover a party’s exposure on the transaction in such situations.

In general, 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.

During the six months ended June 30, 2013, US12OF did not employ any hedging methods such as those described above since all of its investments were made over an exchange. Therefore, during such period, US12OF was not exposed to counterparty risk.

US12OF anticipates that the use of Other Oil-Related Investments together with its investments in Oil Futures Contracts will produce price and total return results that closely track the investment goals of US12OF. However, there can be no assurance of this. OTC Contracts may result in higher transaction-related expenses than the brokerage commissions paid in connection with the purchase of Oil Futures Contracts, which may impact US12OF’s ability to successfully track the Benchmark Oil Futures Contracts.

Item 4. | Controls and Procedures.

Disclosure Controls and Procedures

US12OF maintains disclosure controls and procedures that are designed to ensure that material information required to be disclosed in US12OF’s periodic reports filed or submitted under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the time period specified in the SEC’s rules and forms.

The duly appointed officers of USCF, including its chief executive officer and chief financial officer, who perform functions equivalent to those of a principal executive officer and principal financial officer of US12OF if US12OF had any officers, have evaluated the effectiveness of US12OF’s disclosure controls and procedures and have concluded that the disclosure controls and procedures of US12OF have been effective as of the end of the period covered by this quarterly report on Form 10-Q.
