Notes to Condensed Financial Statements

For the period ended March 31, 2015 (Unaudited)

NOTE 1 — ORGANIZATION AND BUSINESS

The United States 12 Month Natural Gas Fund, LP (“UNL”) was organized as a limited partnership under the laws of the state of Delaware on June 27, 2007. UNL is a commodity pool that issues limited partnership shares (“shares”) that may be purchased and sold on the NYSE Arca, Inc. (the “NYSE Arca”). UNL 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 UNL is for the daily changes in percentage terms of its shares’ per share net asset value (“NAV”) to reflect the daily changes in percentage terms of the price of natural gas delivered at the Henry Hub, Louisiana, as measured by the daily changes in the average of the prices of 12 futures contracts for natural gas 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 UNL’s expenses. When calculating the daily movement of the average price of the 12 contracts, each contract month is equally weighted. It is not the intent of UNL to be operated in a fashion such that the per share NAV will equal, in dollar terms, the spot price of natural gas or any particular futures contract based on natural gas. It is not the intent of UNL to be operated in a fashion such that its per share 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 UNL, believes that it is not practical to manage the portfolio to achieve such an investment goal when investing in Natural Gas Futures Contracts (as defined below) and Other Natural Gas-Related Investments (as defined below). UNL accomplishes its objective through investments in futures contracts for natural gas that are traded on the NYMEX, ICE Futures Exchange (“ICE Futures”) or other U.S. and foreign exchanges (collectively, “Natural Gas Futures Contracts”) and, to a lesser extent, in investments such as cash-settled options on Natural Gas Futures Contracts, forward contracts for natural gas, cleared swap contracts and non-exchange traded over-the-counter (“OTC”) transactions that are based on the price of natural gas, crude oil and other petroleum-based fuels, as well as futures contracts for crude oil, diesel-heating oil, gasoline and other petroleum-based fuels and indices based on the foregoing (collectively, “Other Natural Gas-Related Investments”). Market conditions that USCF currently anticipates could cause UNL to obtain greater liquidity or to execute transactions with more favorable pricing. For convenience and unless otherwise specified, Natural Gas Futures Contracts and Other Natural Gas-Related Investments collectively are referred to as “Natural Gas Interests.” As of March 31, 2015, UNL held 584 Natural Gas Futures Contracts for natural gas traded on the NYMEX and did not hold any Natural Gas Futures Contracts traded on ICE Futures.

UNL commenced investment operations on November 18, 2009 and has a fiscal year ending on December 31. USCF is responsible for the management of UNL. 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 and a swaps firm on August 8, 2013. USCF is also the general partner of the United States Oil Fund, LP (“USO”), the United States Natural Gas Fund, LP (“UNG”), the United States 12 Month Oil Fund, LP (“USL”), the United States Gasoline Fund, LP (“UGA”) and the United States Diesel-Heating Oil Fund, LP (“UHN”), which listed their limited partnership shares on the American Stock Exchange (the “AMEX”) under the ticker symbols “USO” on April 10, 2006, “UNG” on April 18, 2007, “USL” on December 6, 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 USO’s, UNG’s, USL’s, UGA’s and UHN’s shares commenced trading on the NYSE Arca on November 25, 2008. USCF is also the general partner of the United States Short Oil Fund, LP (“DNO”) and United States Brent Oil Fund, LP (“BNO”), which listed their limited partnership shares on the NYSE Arca under the ticker symbols “DNO” on September 24, 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”) and the United States Agriculture Index Fund (“USAG”), each a series of the United States Commodity Index Funds Trust. USCI, CPER and USAG listed their shares on the NYSE Arca under the ticker symbol “USCI” on August 10, 2010, “CPER” on November 15, 2011 and “USAG” on April 13, 2012, respectively. All funds listed previously are referred to collectively herein as the “Related Public Funds.”

UNL issues shares to certain Authorized Participants (“Authorized Participants”) by offering baskets consisting of 50,000 shares (“Creation Baskets”) through ALPS Distributors, Inc., as the marketing agent (the “Marketing Agent”). The purchase price for a Creation Basket is based upon the NAV of a share calculated shortly after the close of the core trading session on the NYSE Arca on the day the order to create the basket is properly received.

Authorized Participants pay UNL a $350 fee for each order placed to create one or more Creation Baskets or to redeem one or more baskets (“Redemption Baskets”). Shares may be purchased or sold on a nationally recognized securities exchange in smaller increments than a Creation Basket or Redemption Basket. Shares purchased or sold on a nationally recognized securities exchange are not purchased or sold at the per share NAV of UNL but rather at market prices quoted on such exchange.

7

In November 2009, UNL initially registered 30,000,000 shares on Form S-1 with the U.S. Securities and Exchange Commission (the “SEC”). On November 18, 2009, UNL listed its shares on the NYSE Arca under the ticker symbol “UNL”. On that day, UNL established its initial per share NAV by setting the price at $50.00 and issued 200,000 shares in exchange for $10,000,000. UNL also commenced investment operations on November 18, 2009 by purchasing Natural Gas Futures Contracts traded on the NYMEX based on natural gas. As of March 31, 2015, UNL had registered a total of 30,000,000 shares.

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

Basis of Presentation

The financial statements have been prepared in conformity with GAAP as detailed in the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification. UNL is an investment company and follows the accounting and reporting guidance in FASB Topic 946.

Revenue Recognition

Commodity futures contracts, forward contracts, physical commodities and related options are recorded on the trade date. All such transactions are recorded on the identified cost basis and marked to market daily. Unrealized gains or losses on open contracts are reflected in the 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. UNL earns interest on its assets denominated in U.S. dollars on deposit with the futures commission merchant (“FCM”). In addition, UNL earns income on funds held at the custodian or FCM at prevailing market rates earned on such investments.

Brokerage Commissions

Brokerage commissions on all open commodity futures contracts are accrued on a full-turn basis.

Income Taxes

UNL 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, UNL 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. UNL files an income tax return in the U.S. federal jurisdiction, and may file income tax returns in various U.S. states. UNL is not subject to income tax return examinations by major taxing authorities for years before 2011. 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 UNL recording a tax liability that reduces net assets. However, UNL’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. UNL 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 March 31, 2015.

Creations and Redemptions

Authorized Participants may purchase Creation Baskets or redeem Redemption Baskets only in blocks of 50,000 shares at a price equal to the NAV of the shares calculated shortly after the close of the core trading session on the NYSE Arca on the day the order is placed.

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

Authorized Participants pay UNL a fee of $350 for each order placed to create one or more Creation Baskets or to redeem one or more Redemption Baskets.

Partnership Capital and Allocation of Partnership Income and Losses

Profit or loss shall be allocated among the partners of UNL in proportion to the number of shares each partner holds as of the close of each month. USCF may revise, alter or otherwise modify this method of allocation as described in the LP Agreement.

Calculation of Per Share Net Asset Value (“NAV”)

UNL’s per share NAV is calculated on each NYSE Arca trading day by taking the current market value of its total assets, subtracting any liabilities and dividing that amount by the total number of shares outstanding. UNL uses the closing price for the contracts on the relevant exchange on that day to determine the value of contracts held on such exchange.

Net Income (Loss) Per Share

Net income (loss) per share is the difference between the per share NAV at the beginning of each period and at the end of each period. The weighted average number of shares outstanding was computed for purposes of disclosing net income (loss) per weighted average share. The weighted average shares are equal to the number of shares outstanding at the end of the period, adjusted proportionately for shares added and redeemed based on the amount of time the shares were outstanding during such period. There were no shares held by USCF at March 31, 2015.

Offering Costs

Offering costs incurred in connection with the registration of additional shares after the initial registration of shares are borne by UNL. 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 UNL in accordance with the objectives and policies of UNL. In addition, USCF has arranged for one or more third parties to provide administrative, custody, accounting, transfer agency and other necessary services to UNL. For these services, UNL is contractually obligated to pay USCF a fee, which is paid monthly, equal to 0.75% per annum of average daily total net assets.

Ongoing Registration Fees and Other Offering Expenses

UNL pays all costs and expenses associated with the ongoing registration of its shares subsequent to the initial offering. These costs include registration or other fees paid to regulatory agencies in connection with the offer and sale of shares, and all legal, accounting, printing and other expenses associated with such offer and sale. For the three months ended March 31, 2015 and 2014, UNL did not incur any registration fees or other offering expenses.

Directors’ Fees and Expenses

UNL is responsible for paying its portion of the directors’ and officers’ liability insurance for UNL and the Related Public Funds and the fees and expenses of the independent directors who also serve as audit committee members of UNL and the Related Public Funds. UNL shares the fees and expenses on a pro rata basis with each Related Public Fund, as described above, based on the relative assets of each Related Public Fund computed on a daily basis. These fees and expenses for the year ending December 31, 2015 are estimated to be a total of $4,644 for UNL and $560,625 for UNL and the Related Public Funds.

Licensing Fees

UNL and the Related Public Funds, other than BNO, USCI, CPER and USAG, pay a licensing fee that is equal to 0.015% on all net assets. During the three months ended March 31, 2015 and 2014, UNL incurred $649 and $894, respectively, under this arrangement.

Investor Tax Reporting Cost

The fees and expenses associated with UNL’s audit expenses and tax accounting and reporting requirements are paid by UNL. These costs are estimated to be $86,000 for the year ending December 31, 2015.

Other Expenses and Fees and Expense Waivers

In addition to the fees described above, UNL pays all brokerage fees and other expenses in connection with the operation of UNL, excluding costs and expenses paid by USCF as outlined in Note 4 – Contracts and Agreements below. USCF has voluntarily agreed to pay certain expenses normally borne by UNL to the extent that such expenses exceed 0.15% (15 basis points) of UNL’s NAV, on an annualized basis, through at least June 30, 2015. USCF has no obligation to continue such payments into subsequent periods. For the three months ended March 31, 2015, USCF waived $17,835 of UNL’s expenses. This voluntary expense waiver is in addition to those amounts USCF is contractually obligated to pay as described in Note 4 – Contracts and Agreements.

NOTE 4 — CONTRACTS AND AGREEMENTS

UNL is party to a marketing agent agreement, dated as of October 30, 2009, as amended from time to time, with the Marketing Agent and USCF, whereby the Marketing Agent provides certain marketing services for UNL as outlined in the agreement. The fee of the Marketing Agent, which is borne by USCF, is equal to 0.06% on UNL’s assets up to $3 billion and 0.04% on UNL’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 UNL’s offering.

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

UNL is also party to a custodian agreement, dated November 3, 2009, as amended from time to time, with Brown Brothers Harriman & Co. (“BBH&Co.”) and USCF, whereby BBH&Co. holds investments on behalf of UNL. USCF pays the fees of the custodian, which are determined by the parties from time to time. In addition, UNL is party to an administrative agency agreement, dated November 3, 2009, as amended from time to time, with USCF and BBH&Co., whereby BBH&Co. acts as the administrative agent, transfer agent and registrar for UNL. 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 UNL 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 the Related Public Funds’ combined net assets, (b) 0.0465% for the Related Public Funds’ combined net assets greater than $500 million but less than $1 billion, and (c) 0.035% once the Related Public Funds’ 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.

On October 8, 2013, UNL entered into a brokerage agreement with RBC Capital Markets, LLC (“RBC Capital” or “RBC”) to serve as UNL’s FCM, effective October 10, 2013. Prior to October 10, 2013, the FCM was UBS Securities LLC. The agreement with RBC requires it to provide services to UNL in connection with the purchase and sale of Natural Gas Futures Contracts and Other Natural Gas-Related Investments that may be purchased and sold by or through RBC Capital and/or UBS Securities for UNL’s account. In accordance with the agreement, RBC Capital charges UNL commissions of approximately $7 to $15 per round-turn trade, including applicable exchange and NFA fees for Natural Gas Futures Contracts and options on Natural Gas Futures Contracts. Such fees include those incurred when purchasing Natural Gas Futures Contracts and options on Natural Gas Futures Contracts when UNL issues shares as a result of a Creation Basket, as well as fees incurred when selling Natural Gas Futures Contracts and options on Natural Gas Futures Contracts when UNL redeems shares as a result of a Redemption Basket. Such fees are also incurred when Natural Gas Futures Contracts and options on Natural Gas Futures Contracts are purchased or redeemed for the purpose of rebalancing the portfolio. UNL also incurs commissions to brokers for the purchase and sale of Natural Gas Futures Contracts, Other Natural Gas-Related Investments or short-term obligations of the United States of two years or less (“Treasuries”).

|  | For the three months ended March 31, 2015 |  |  | For the three months ended March 31, 2014 |
Total commissions accrued to brokers |  | $ | 1,595 |  |  | $ | 2,070 |
Total commissions as an annualized percentage of average net assets |  |  | 0.04 | % |  |  | 0.03 | %
Commissions accrued as a result of rebalancing |  | $ | 969 |  |  | $ | 1,072 |
Percentage of commissions accrued as a result of rebalancing |  |  | 60.78 | % |  |  | 51.79 | %
Commissions accrued as a result of creation and redemption activity |  | $ | 626 |  |  | $ | 998 |
Percentage of commissions accrued as a result of creation and redemption activity |  |  | 39.22 | % |  |  | 48.21 | %

The decrease in UNL’s total commissions accrued to brokers for the three months ended March 31, 2015, as compared to the three months ended March 31, 2014, was a result of a lower number of futures contracts being held and traded as a result of UNL’s reduced net assets during the three months ended March 31, 2015.

UNL and the NYMEX entered into a licensing agreement on December 4, 2007, as amended on October 20, 2011, whereby UNL was granted a non-exclusive license to use certain of the NYMEX’s settlement prices and service marks. Under the licensing agreement, UNL and the Related Public Funds, other than BNO, USCI, CPER and USAG, pay the NYMEX an asset-based fee for the license, the terms of which are described in Note 3. UNL expressly disclaims any association with the NYMEX or endorsement of UNL 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

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

UNL may enter into futures contracts, options on futures contracts and cleared swaps to gain exposure to changes in the value of an underlying commodity. A futures contract obligates the seller to deliver (and the purchaser to accept) the future delivery of a specified quantity and type of a commodity at a specified time and place. Some futures contracts may call for physical delivery of the asset, while others are settled in cash. The contractual obligations of a buyer or seller may generally be satisfied by taking or making physical delivery of the underlying commodity or by making an offsetting sale or purchase of an identical futures contract on the same or linked exchange before the designated date of delivery. Cleared swaps are OTC agreements that are eligible to be cleared by a clearinghouse, e.g., ICE Clear Europe, but which are not traded on an exchange. A cleared swap is created when the parties to an off-exchange OTC swap transaction agree to extinguish their OTC contract and replace it with a cleared swap. Cleared swaps are intended to provide the efficiencies and benefits that centralized clearing on an exchange offers to traders of futures contracts, including credit risk intermediation and the ability to offset positions initiated with different counterparties.

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

Futures contracts, options on futures contracts and cleared swaps involve, to varying degrees, elements of market risk (specifically commodity price risk) and exposure to loss in excess of the amount of variation margin. The face or contract amounts reflect the extent of the total exposure UNL has in the particular classes of instruments.

11

Additional risks associated with the use of futures contracts are an imperfect correlation between movements in the price of the futures contracts and the market value of the underlying securities and the possibility of an illiquid market for a futures contract. Buying and selling options on futures contracts exposes investors to the risks of purchasing or selling futures contracts.

All of the futures contracts held by UNL were exchange-traded through March 31, 2015. The risks associated with exchange-traded contracts are generally perceived to be less than those associated with OTC transactions since, in OTC transactions, a party must rely solely on the credit of its respective individual counterparties. However, in the future, if UNL were to enter into non-exchange traded contracts, it would be subject to the credit risks associated with counterparty non-performance. OTC transactions subject UNL 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. UNL 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, UNL bears the risk of financial failure by the clearing broker.

UNL’s cash and other property, such as Treasuries, deposited with a FCM are considered commingled with all other customer funds, subject to the FCM’s segregation requirements. In the event of a FCM’s insolvency, recovery may be limited to a pro rata share of segregated funds available. It is possible that the recovered amount could be less than the total of cash and other property deposited. The insolvency of a FCM could result in the complete loss of UNL’s assets posted with that FCM; however, the majority of UNL’s assets are held in cash and/or cash equivalents with UNL’s custodian and would not be impacted by the insolvency of a FCM. The failure or insolvency of UNL’s custodian, however, could result in a substantial loss of UNL’s assets.

USCF invests a portion of UNL’s cash in money market funds that seek to maintain a stable per share NAV. UNL is exposed to any risk of loss associated with an investment in such money market funds. As of March 31, 2015 and December 31, 2014, UNL held investments in money market funds in the amounts of $9,510,692 and $9,510,692, respectively. UNL 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 March 31, 2015 and December 31, 2014, UNL held cash deposits and investments in Treasuries in the amounts of $11,481,181 and $11,127,927, respectively, with the custodian and FCM. Some or all of these amounts may be subject to loss should UNL’s custodian and/or FCM cease operations.

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

UNL’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, UNL 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 UNL 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 7 — FAIR VALUE OF FINANCIAL INSTRUMENTS

UNL 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 UNL (observable inputs) and (2) UNL’s own assumptions about market participant assumptions developed based on the best information available under the circumstances (unobservable inputs). The three levels defined by the ASC 820 hierarchy are as follows:

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

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

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

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

The following table summarizes the valuation of UNL’s securities at March 31, 2015 using the fair value hierarchy:

At March 31, 2015 |  | Total |  |  | Level I |  |  | Level II |  |  | Level III |
Short-Term Investments |  | $ | 12,510,559 |  |  | $ | 12,510,559 |  |  | $ | — |  |  | $ | — |

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 Natural Gas Fund, LP (“UNL”) 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 UNL’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 UNL’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 UNL cannot assure investors that the projections included in these forward-looking statements will come to pass. UNL’s actual results could differ materially from those expressed or implied by the forward-looking statements as a result of various factors.

UNL 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 UNL assumes no obligation to update any such forward-looking statements. Although UNL 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 UNL may make directly to them or through reports that UNL 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

UNL, a Delaware limited partnership, is a commodity pool that issues shares that may be purchased and sold on the NYSE Arca, Inc. (the “NYSE Arca”). The investment objective of UNL is for the daily changes in percentage terms of its shares’ per share net asset value (“NAV”) to reflect the daily changes, in percentage terms, of the price of natural gas delivered at the Henry Hub, Louisiana, as measured by the daily changes, in percentage terms, in the average of the prices of 12 futures contracts on natural gas 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 UNL’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 is equally weighted. It is not the intent of UNL to be operated in a fashion such that the per share NAV will equal, in dollar terms, the spot price of natural gas or any particular futures contract based on natural gas. It is not the intent of UNL to be operated in a fashion such that its per share NAV will reflect the percentage change of the price of any particular futures contracts as measured over a time period greater than one day. The general partner of UNL, 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 Natural Gas Futures Contracts (as defined below) and Other Natural Gas-Related Investments (as defined below).

UNL accomplishes its objective through investments in futures contracts for natural gas that are traded on the NYMEX, ICE Futures Exchange (“ICE Futures”) or other U.S. and foreign exchanges (collectively, “Natural Gas Futures Contracts”) and, to a lesser extent, in investments such as cash-settled options on Natural Gas Futures Contracts, forward contracts for natural gas, cleared swap contracts and non-exchange traded over-the-counter (“OTC”) transactions that are based on the price of natural gas, crude oil and other petroleum-based fuels and indices based on the foregoing (collectively, “Other Natural Gas-Related Investments”). Market conditions that USCF currently anticipates could cause UNL to invest in Other Natural Gas-Related Investments include those allowing UNL to obtain greater liquidity or to execute transactions with more favorable pricing. For convenience and unless otherwise specified, Natural Gas Futures Contracts and Other Natural Gas-Related Investments collectively are referred to as “Natural Gas Interests” in this quarterly report on Form 10-Q.

UNL seeks to achieve its investment objective by investing in a combination of Natural Gas Futures Contracts and Other Natural Gas-Related Investments such that daily changes in its per share NAV, measured in percentage terms, will closely track the daily changes in the average of the prices of the Benchmark Futures Contracts, also measured in percentage terms. USCF believes the daily changes in the average of the prices of the Benchmark Futures Contracts have historically exhibited a close correlation with the daily changes in the spot price of natural gas. It is not the intent of UNL to be operated in a fashion such that the per share NAV will equal, in dollar terms, the spot price of natural gas or any particular futures contract based on natural gas. It is not the intent of UNL to be operated in a fashion such that its per share NAV will reflect the percentage change of the price of any particular futures contracts 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 listed Natural Gas Futures Contracts and Other Natural Gas-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 UNL 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 Natural Gas Futures Contracts traded on 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 any one-month in the Benchmark Futures Contracts is 6,000 net contracts. In addition, the NYMEX imposes an accountability levels for all months of 12,000 net futures contracts for investments in futures contracts for natural gas. In addition, the ICE Futures maintains the same accountability levels, position limits and monitoring authority for its natural gas contracts as the NYMEX. If UNL and the Related Public Funds (as defined below) exceed these accountability levels for investments in the futures contract for natural gas, the NYMEX and ICE Futures will monitor UNL’s and the Related Public Funds’ 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 UNL and the Related Public Funds. If deemed necessary by the NYMEX and/or ICE Futures, UNL and the Related Public Funds could be ordered to reduce their aggregate net position back to the accountability level. As of March 31, 2015, UNL held 584 Natural Gas NG Futures Contracts traded on the NYMEX and did not hold any Natural Gas Futures Contracts traded on ICE Futures. For the three months ended March 31, 2015, UNL did not exceed accountability levels imposed by the NYMEX and 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 UNL will run up against such position limits because UNL’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 three months ended March 31, 2015, UNL 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. The various statements made in this summary are subject to modification by legislative action and changes in the rules and regulations of the SEC, Financial Industry Regulatory Authority (“FINRA”), CFTC, the National Futures Association (the “NFA”), the futures exchanges, clearing organizations and other regulatory bodies.

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.

On November 5, 2013, the CFTC proposed a rulemaking that would establish specific limits on speculative positions in 28 physical commodity futures and option contracts as well as swaps that are economically equivalent to such contracts in the agriculture, energy and metals markets (the “Position Limit Rules”). On the same date, the CFTC proposed another rule addressing the circumstances under which market participants would be required to aggregate their positions with other persons under common ownership or control (the “Proposed Aggregation Requirements”). Specifically, the Position Limit Rules would, among other things: identify which contracts are subject to speculative position limits; set thresholds that restrict the number of speculative positions that a person may hold in a spot month, individual month, and all months combined; create an exemption for positions that constitute bona fide hedging transactions; impose responsibilities on designated contract markets (“DCMs”) and swap execution facilities (“SEFs”) to establish position limits or, in some cases, position accountability rules; and apply to both futures and swaps across four relevant venues: OTC, DCMs, SEFs as well as non-U.S. located platforms. Until such time as the Position Limit Rules are adopted, the regulatory architecture in effect prior to the adoption 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, UNL 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 Position Limit Rules require 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 OTC swaps. Under the CFTC’s existing position limits requirements and the Position Limit Rules, a market participant is generally required to aggregate all positions for which that participant controls the trading decisions with all positions for which that participant has a 10 percent or greater ownership interest in an account or position, as well as the positions of two or more persons acting pursuant to an express or implied agreement or understanding. At this time, it is unclear how the Proposed Aggregation Requirements may affect UNL, but it may be substantial and adverse. By way of example, the Proposed Aggregation Requirements in combination with the Position Limit Rules may negatively impact the ability of UNL to meet its investment objectives through limits that may inhibit USCF’s ability to sell additional Creation Baskets of UNL. See “Commodity Interest Markets – Regulation” in this quarterly report on Form 10-Q for additional information.

16

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

“Swap” Transactions

The Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) imposes regulatory requirements on certain “swap” transactions that UNL is authorized to engage in that may ultimately impact the ability of UNL to meet its investment objective. The term “swap” is broadly defined to include various types of OTC derivatives, including swaps and options.

Regulations require 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 (“derivative clearing organizations” (“DCOs”)), if the CFTC mandates the central clearing of a particular contract. As of June 10, 2013, swap dealers, major swap participants, commodity pools, certain private funds and entities predominantly engaged in financial activities were required to clear certain credit default swaps and interest rate swaps. As a result, if UNL enters into or has entered into certain interest rate and credit default swaps, 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 UNL to centrally clear certain OTC 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 organizations, 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.”

Current rules and regulations also require that certain swaps determined to be available to trade on a SEF must be executed over such a facility, including the obligation for facilities offering multiple person execution services. Based upon applications filed by several SEFs with the CFTC, the CFTC has determined that certain interest rate swaps and credit default index swaps must register as a SEF and be executed on a SEF.

Current rules and regulations 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 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 the 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.

On November 6, 2013, the CFTC published a final rule that imposes requirements on swap dealers and major swap participants with respect to the treatment of collateral posted by their counterparties to margin, guarantee, or secure uncleared swaps. In other words, the rule places restrictions on what swap dealers and major swap participants can do with collateral posted by UNL in connection with uncleared swaps.

In addition to the rules and regulations imposed under the Dodd-Frank Act, swap dealers that are European banks may also be subject to European Market Infrastructure Regulation (“EMIR”). These regulations have not yet been fully implemented.

17

On August 12, 2013, the CFTC issued final rules establishing compliance obligations for commodity pool operators (“CPOs”) of investment companies registered under the Investment Company Act of 1940 (the “Investment Company Act”) that are required to register due to recent changes to CFTC Regulation 4.5. The final rules were issued in a CFTC release entitled “Harmonization of Compliance Obligations for Registered Investment Companies Required to Register as Commodity Pool Operators.” For entities that are registered with both the CFTC and the SEC, the CFTC will accept the SEC’s disclosure, reporting and recordkeeping regime as substituted compliance for substantially all of Part 4 of the CFTC’s regulations, so long as they comply with comparable requirements under the SEC’s statutory and regulatory compliance regime. Thus, the final rules (the “Harmonization Rules”) allow dually registered entities to meet certain CFTC regulatory requirements for CPOs by complying with SEC rules to which they are already subject. Although UNL is not a registered investment company under the Investment Company Act, the Harmonization Rules amended certain CFTC disclosure rules to make the requirements for all CPOs to periodically update their disclosure documents consistent with those of the SEC. This change will decrease the burden to UNL and USCF of having to comply with inconsistent regulatory requirements. It is not known whether the CFTC will make additional amendments to its disclosure, reporting and recordkeeping rules to further harmonize these obligations with those of the SEC as they apply to UNL and USCF, but any such further rule changes could result in additional operating efficiencies for UNL and USCF.

Money Market Reform

On July 23, 2014, the SEC adopted to reform money market funds such that institutional prime money market funds will float their net asset value as well as impose rules such that all money market funds’ boards of directors will be required to implement rules to discourage and prevent runs by investors through the use of redemption fees and gates. Money market funds have two years from the date of adoption to implement the reform. UNL currently invests in money market funds, as well as Treasuries with a maturity date of two years or less, as an investment for assets not used for margin or collateral in the Natural Gas Futures Contracts. It is unclear at this time what the impact of money market reform would have on UNL’s ability to hedge risk, however, the imposition of a floating net asset value could cause UNL to limit remaining assets solely in Treasuries and cash.

As the regulatory requirements are constantly evolving, it is difficult to predict the effect any regulatory changes may have on UNL.

Price Movements

Natural gas futures prices were volatile during the three months ended March 31, 2015. The average price of the Benchmark Futures Contracts started the period at $3.057. It rose during the course of the period and hit a peak on January 14, 2015 of $3.248. The average low price of the period was on February 5, 2015, when the average price of the Benchmark Futures Contracts was $2.839. The average price of the Benchmark Futures Contracts on March 31, 2015 was $2.912, a decrease of approximately 4.74% over the period. UNL’s per share NAV began the period at $13.69 and ended the period at $12.60 on March 31, 2015, a decrease of approximately 7.96% over the period. UNL’s per share NAV reached its high for the period on January 14, 2015 at $14.54 and reached its low for the period on March 27, 2015 at $12.58. The average Benchmark Futures Contract prices listed above began with the February 2015 contract to January 2016 contracts and ended with the May 2015 to April 2016 contracts. The decrease of approximately 4.74% on the average price of the Benchmark Futures Contracts listed above is a hypothetical return only and could not actually be achieved by an investor holding Natural Gas Futures Contracts. An investment in Natural Gas 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 Natural Gas Futures Contracts, measured from the start of the period to the end of the period, does not represent the actual benchmark results that UNL seeks to track, which are more fully described below in the section titled “Tracking UNL’s Benchmark.”

During the three months ended March 31, 2015, the natural gas futures market exhibited periods of both contango and backwardation. During periods of contango, the price of the near month natural gas Futures Contract was typically lower than the price of the next month natural gas Futures Contract, or contracts further away from expiration. On days when the market was in backwardation, the price of the near month natural gas Futures Contract was typically higher than the price of the next month natural gas Futures Contract, or contracts further away from expiration. For a discussion of the impact of contango and backwardation on total returns, see “Term Structure of Natural Gas Futures Prices and the Impact on Total Returns” below.

Valuation of Natural Gas Futures Contracts and the Computation of the Per Share NAV

The per share NAV of UNL’s shares is calculated once each NYSE Arca trading day. The per share 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. UNL’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 UNL investments, including cleared swaps, 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 Natural Gas Market

Results of Operations. On November 18, 2009, UNL listed its shares on the NYSE Arca under the ticker symbol “UNL.” On that day, UNL established its initial offering price at $50.00 per share and issued 200,000 shares to the initial Authorized Participant in exchange for $10,000,000 in cash.

Since its initial offering of 30,000,000 shares, UNL has not registered any subsequent offerings of its shares. As of March 31, 2015, UNL had issued 4,700,000 shares, 1,350,000 of which were outstanding. As of March 31, 2015, there were 25,300,000 shares registered but not yet issued.

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

As of March 31, 2015, UNL had the following Authorized Participants: Citigroup Global Markets Inc., Credit Suisse Securities (USA) LLC, JP Morgan Securities Inc., Merrill Lynch Professional Clearing Corporation, Morgan Stanley & Company Inc., NewEdge USA LLC, Nomura Securities International Inc., RBC Capital Markets LLC, SG Americas Securities LLC and Virtu Financial BD LLC.

Portfolio Expenses. UNL’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 UNL pays to USCF is calculated as a percentage of the total net assets of UNL. The fee is accrued daily and paid monthly.

Average interest rates earned on short-term investments held by UNL, including cash, cash equivalents and Treasuries, were similar during the three months ended March 31, 2015, compared to the three months ended March 31, 2014. As a result, the amount of income earned by UNL as a percentage of average daily total net assets was similar during the three months ended March 31, 2015.

The decrease in gross total expenses excluding management fees for the three months ended March 31, 2015, compared to the three months ended March 31, 2014, was primarily due to a decrease in certain of UNL’s operating expenses.

The decrease in UNL’s total commissions accrued to brokers for the three months ended March 31, 2015, as compared to the three months ended March 31, 2014, was a result of a lower number of futures contracts being held and traded as a result of UNL’s reduced net assets during the three months ended March 31, 2015.

Tracking UNL’s Benchmark

USCF seeks to manage UNL’s portfolio such that changes in its average daily per share NAV, on a percentage basis, closely track the daily changes in the average of the prices of the Benchmark 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 UNL’s per share 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 Futures Contracts. As an example, if the average daily movement of the average of the prices of the Benchmark 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 share 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). UNL’s portfolio management goals do not include trying to make the nominal price of UNL’s per share NAV equal to the average of the nominal prices of the current Benchmark Futures Contracts or the spot price for natural gas. USCF believes that it is not practical to manage the portfolio to achieve such an investment goal when investing in Natural Gas Futures Contracts and Other Natural Gas-Related Investments.

For the 30 valuation days ended March 31, 2015, the simple average daily change in the average of the Benchmark Futures Contracts was (0.153)%, while the simple average daily change in the per share NAV of UNL over the same time period was (0.157)%. 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 average price of the Benchmark Futures Contracts, the average error in daily tracking by the per share NAV was (0.728)%, meaning that over this time period UNL’s tracking error was within the plus or minus 10% range established as its benchmark tracking goal.

Since the commencement of the offering of UNL shares to the public on November 18, 2009 to March 31, 2015, the simple average daily change in the average price of its Benchmark Futures Contracts was (0.082)%, while the simple average daily change in the per share NAV of UNL over the same time period was (0.086)%. The average daily difference was (0.003)% (or (0.3) basis points, where 1 basis point equals 1/100 of 1%). As a percentage of the daily movement of the average price of the Benchmark Futures Contracts, the average error in daily tracking by the per share NAV was (0.77)%, meaning that over this time period UNL’s tracking error was within the plus or minus 10% range established as its benchmark tracking goal. The following two graphs demonstrate the correlation between the changes in UNL’s NAV and the changes in the Benchmark Futures Contract. The first graph exhibits the daily changes for the last 30 valuation days ended March 31, 2015; the second graph measures monthly changes from March 31, 2010 through March 31, 2015.

*PAST PERFORMANCE IS NOT NECESSARILY INDICATIVE OF FUTURE RESULTS

20

*PAST PERFORMANCE IS NOT NECESSARILY INDICATIVE OF FUTURE RESULTS

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

For the three months ended March 31, 2015, the actual total return of UNL as measured by changes in its per share NAV was (7.96)%. This is based on an initial per share NAV of $13.69 as of December 31, 2014 and an ending per share NAV as of March 31, 2015 of $12.60. During this time period, UNL made no distributions to its shareholders. However, if UNL’s daily changes in its per share NAV had instead exactly tracked the changes in the daily total return of the Benchmark Futures Contracts, UNL would have had an estimated per share NAV of $12.62 as of March 31, 2015, for a total return over the relevant time period of (7.82)%. The difference between the actual per share NAV total return of UNL of (7.96)% and the expected total return based on the Benchmark Futures Contracts of (7.82)% was an error over the time period of (0.15)%, which is to say that UNL’s actual total return underperformed the benchmark result by that percentage. UNL incurs expenses primarily composed of the management fee, brokerage commissions for the buying and selling of futures contracts, and other expenses. The impact of these expenses tends to cause daily changes in the per share NAV of UNL to track slightly lower than daily changes in the price of the Benchmark Futures Contract.

By comparison, for the three months ended March 31, 2014, the actual total return of UNL as measured by changes in its per share NAV was 7.15%. This was based on an initial per share NAV of $18.32 as of December 31, 2013 and an ending per share NAV as of March 31, 2014 of $19.63. During this time period, UNL made no distributions to its shareholders. However, if UNL’s daily changes in its per share NAV had instead exactly tracked the changes in the daily total return of the Benchmark Futures Contracts, UNL would have had an estimated per share NAV of $19.67 as of March 31, 2014, for a total return over the relevant time period of 7.37%. The difference between the actual per share NAV total return of UNL of 7.15% and the expected total return based on the Benchmark Futures Contracts of 7.37% was an error over the time period of (0.22)%, which is to say that UNL’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 UNL pays, offset in part by the income that UNL collects on its cash and cash equivalent holdings.

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

First, UNL may buy or sell its holdings in the then current Benchmark Futures Contracts at a price other than the closing settlement price of that contract on the day during which UNL executes the trade. In that case, UNL may pay a price that is higher, or lower, than that of the Benchmark Futures Contracts, which could cause the changes in the daily per share NAV of UNL to either be too high or too low relative to the daily changes in the Benchmark Futures Contracts. During the three months ended March 31, 2015, USCF attempted to minimize the effect of these transactions by seeking to execute its purchase or sale of the Benchmark Futures Contracts at, or as close as possible to, the end of the day settlement price. However, it may not always be possible for UNL 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 UNL’s attempt to track the Benchmark Futures Contracts over time.

21

Second, UNL incurs expenses primarily composed of the management fee, brokerage commissions for the buying and selling of futures contracts, and other expenses. The impact of these expenses tends to cause daily changes in the per share NAV of UNL to track slightly lower than the inverse of daily changes in the price of the Benchmark Futures Contract. At the same time, UNL earns dividend and interest income on its cash, cash equivalents and Treasuries. UNL is not required to distribute any portion of its income to its shareholders and did not make any distributions to shareholders during the three months ended March 31, 2015. Interest payments, and any other income, were retained within the portfolio and added to UNL’s NAV. When this income exceeds the level of UNL’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), UNL will realize a net yield that will tend to cause daily changes in the per share NAV of UNL to track slightly higher than daily changes in the average of the prices of the Benchmark Futures Contracts.

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 share NAV to underperform the daily returns of the Benchmark 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 UNL will continue to be higher than interest earned by UNL. As such, USCF anticipates that UNL will continue to underperform its benchmark until such a time when interest earned at least equals or exceeds the fees and expenses paid by UNL.

Third, UNL may hold Other Natural Gas-Related Investments in its portfolio that may fail to closely track the Benchmark Futures Contracts’ total return movements. In that case, the error in tracking the changes in the average of the Benchmark Futures Contracts could result in daily changes in the per share NAV of UNL that are either too high, or too low, relative to the daily changes in the average of the Benchmark Futures Contracts. During the three months ended March 31, 2015, UNL did not hold Other Natural Gas-Related Investments. If UNL increases in size, and due to its obligations to comply with regulatory limits, UNL may invest in Other Natural Gas-Related Investments which may have the effect of increasing transaction related expenses and may result in increased tracking error.

Term Structure of Natural Gas 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 natural gas 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 natural gas for immediate delivery (the “spot” price), was $7 per 10,000 million British thermal shares (“MMBtu”), and the value of a position in the near month futures contract was also $7. Over time, the price of 10,000 MMBtu of natural gas will fluctuate based on a number of market factors, including demand for natural gas 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 natural gas, 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 natural gas 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 $7 per MMBtu price above to represent the front month price, the price of the next month contract could be $6.86 per barrel, that is, 2% cheaper than the front month contract. Hypothetically, and assuming no other changes to either prevailing natural gas 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 $6.86 next month contract would rise as it approaches expiration and becomes the new near month contract with a price of $7. In this example, the value of an investment in the second month contract would tend to rise faster than the spot price of natural gas, or fall slower. As a result, it would be possible in this hypothetical example for the spot price of natural gas 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 natural gas 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.

22

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 $7 per MMBtu price above to represent the front month price, the price of the next month contract could be $7.14 per barrel, that is, 2% more expensive than the front month contract. Hypothetically, and assuming no other changes to either prevailing natural gas 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 $7. 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 natural gas, or fall faster. As a result, it would be possible in this hypothetical example for the spot price of natural gas 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 natural gas 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 natural gas. 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). In addition, investors can observe that natural gas prices, both front month and second month, often display a seasonal pattern in which the price of natural gas tends to rise in the early winter months and decline in the summer months. This mirrors the physical demand for natural gas, which typically peaks in the winter.

An alternative way to view backwardation and contango data over time is to subtract the dollar price of the near month natural gas Futures Contract from the dollar price of the near 12 month Natural Gas Futures Contracts. 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 March 31, 2005 and March 31, 2015. Investors will note that the natural gas market spent time in both backwardation and contango. Investors will further note that the markets display a seasonal pattern that corresponds to the seasonal demand patterns for natural gas above. That is, in many, but not all, cases the average price of the near 12-month contracts is higher than the near month during the approach to the winter months as the price of natural gas for delivery in those winter months rises on expectations of demand. At the same time, the price of the near month, when that month is just before the onset of winter, does not rise as far or as fast as the average price of the near 12-month contracts whose delivery falls during the winter season.

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 natural gas 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 natural gas 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 natural gas. 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 12 month contract.

HYPOTHETICAL PERFORMANCE RESULTS HAVE MANY INHERENT LIMITATIONS, SOME OF WHICH ARE DESCRIBED BELOW. NO REPRESENTATION IS BEING MADE THAT UNL 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 UNL or any Related Public Fund.

Historically, the natural gas futures markets have experienced periods of contango and backwardation. Because natural gas demand is seasonal, it is possible for the price of Natural Gas Futures Contracts for delivery within one or two months to rapidly move from backwardation into contango and back again within a relatively short period of time of less than one year.

26

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 UNL’s investment objective of having the daily percentage changes in its per share NAV track the daily percentage changes in the average of the prices of the Benchmark Futures Contracts since the impact of backwardation and contango tend to equally impact the daily percentage changes in price of both UNL’s shares and the Benchmark 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 and, because of the seasonal nature of natural gas demand, both may occur within a single year’s time.

Natural Gas Market. During the three months ended March 31, 2015, natural gas prices in the United States were volatile and finished the period lower than the beginning of the year. Prices were impacted by several factors. Seasonal demand and persistent cold in some parts of the country was offset by warmer weather in the western United States and record natural gas production. Storage levels fell persistently during the first quarter, but were significantly higher than the same time one year ago. Storage levels were also trended near the five-year-average storage level throughout the quarter, though ending somewhat lower. As of March 31, 2015, the amount of natural gas in storage had reached 1,461 billion cubic feet, which was approximately 12% below the five-year average and 77% above 2014 levels.

Natural Gas 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 March 31, 2005 and March 31, 2015, 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 natural gas on a monthly basis was neither strongly correlated nor inversely correlated with the movements of Large Cap U.S. equities, U.S. government bonds, global equities, crude oil, diesel-heating oil or unleaded gasoline.

The table below covers a more recent, but much shorter, range of dates than the above table. It can be seen that over this particular time period, the movement of natural gas on a monthly basis was neither strongly correlated nor inversely correlated with large cap U.S. equities, U.S. government bonds, global equities, crude oil and diesel-heating oil. However, movements in natural gas were strongly correlated to movements in unleaded gasoline.

*PAST PERFORMANCE IS NOT NECESSARILY INDICATIVE OF FUTURE RESULTS

Investors are cautioned that the historical price relationships between natural gas 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 natural gas 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 natural gas could have long-term correlation results that indicate prices of natural gas 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 natural gas 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 natural gas, crude oil, diesel-heating oil and gasoline are relevant because USCF endeavors to invest UNL’s assets in Natural Gas Futures Contracts and Other Natural Gas-Related Investments so that daily changes in percentage terms in UNL’s per share NAV correlate as closely as possible with daily changes in percentage terms in the average of the prices of the Benchmark Futures Contracts. If certain other fuel-based commodity Natural Gas Futures Contracts do not closely correlate with the Benchmark 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 average of the prices of the Benchmark Futures Contracts will closely correlate with changes in percentage terms in the spot price of natural gas.

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. UNL’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 UNL’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 OTC contracts) involves a critical accounting policy. The values which are used by UNL for its Natural Gas Futures Contracts are provided by its commodity broker who uses market prices when available, while OTC 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, UNL 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.

28

Liquidity and Capital Resources

UNL has not made, and does not anticipate making, use of borrowings or other lines of credit to meet its obligations. UNL has met, and it is anticipated that UNL 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. UNL’s liquidity needs include: redeeming shares, providing margin deposits for its existing Natural Gas Futures Contracts or the purchase of additional Natural Gas Futures Contracts and posting collateral for its OTC contracts and payment of its expenses, summarized below under “Contractual Obligations.”

UNL currently generates cash primarily from: (i) the sale of baskets consisting of 50,000 shares (“Creation Baskets”) and (ii) income earned on Treasuries, cash and/or cash equivalents. UNL has allocated substantially all of its net assets to trading in Natural Gas Interests. UNL invests in Natural Gas 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 Natural Gas Futures Contracts and Other Natural Gas-Related Investments. A significant portion of UNL’s NAV is held in cash and cash equivalents that are used as margin and as collateral for its trading in Natural Gas Interests. The balance of the assets is held in UNL’s account at its custodian bank and in investments in Treasuries at the FCM. Income received from UNL’s investments in money market funds and Treasuries is paid to UNL. During the three months ended March 31, 2015, UNL’s expenses exceeded the income UNL earned and the cash earned from the sale of Creation Baskets and the redemption of Redemption Baskets. During the three months ended March 31, 2015, UNL used other assets to pay expenses, which could cause a decrease in UNL’s NAV over time. To the extent expenses exceed income, UNL’s NAV will be negatively impacted.

UNL’s investments in Natural Gas 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 UNL from promptly liquidating its positions in Natural Gas Futures Contracts. During the three months ended March 31, 2015, UNL did not purchase or liquidate any of its positions while daily limits were in effect; however, UNL cannot predict whether such an event may occur in the future.

Since the initial offering of UNL, all payments with respect to UNL’s expenses were paid by USCF. UNL does not have an obligation or intention to refund such payments made by USCF. USCF is under no obligation to pay UNL’s current or future expenses. UNL is responsible for expenses incurred subsequent to the initial offering of shares 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 shares 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 UNL’s Marketing Agent, Administrator and Custodian and registration expenses relating to the initial offering of shares. If USCF and UNL are unsuccessful in raising sufficient funds to cover these respective expenses or in locating any other source of funding, UNL will terminate and investors may lose all or part of their investment.

Market Risk

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

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

29

Credit Risk

When UNL enters into Natural Gas Futures Contracts and Other Natural Gas-Related Investments, it is exposed to the credit risk that the counterparty will not be able to meet its obligations. The counterparty for the Natural Gas 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 UNL in such circumstances.

USCF attempts to manage the credit risk of UNL by following various trading limitations and policies. In particular, UNL generally posts margin and/or holds liquid assets that are approximately equal to the market value of its obligations to counterparties under the Natural Gas Futures Contracts and Other Natural Gas-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 UNL to limit its credit exposure. An FCM, when acting on behalf of UNL in accepting orders to purchase or sell Natural Gas Futures Contracts on United States exchanges, is required by CFTC regulations to separately account for and segregate as belonging to UNL, all assets of UNL relating to domestic Natural Gas Futures Contracts trading. These FCMs are not allowed to commingle UNL’s assets with their other assets. In addition, the CFTC requires commodity brokers to hold in a secure account UNL’s assets related to foreign Natural Gas Futures Contracts trading.

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

As of March 31, 2015, UNL held cash deposits and investments in Treasuries and money market funds in the amount of $20,991,873 with the custodian and FCM. Some or all of these amounts may be subject to loss should UNL’s custodian and/or FCM cease operations.

Off Balance Sheet Financing

As of March 31, 2015, UNL 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 UNL. While UNL’s exposure under these indemnification provisions cannot be estimated, they are not expected to have a material impact on UNL’s financial position.

European Sovereign Debt

UNL had no direct exposure to European sovereign debt as of March 31, 2015 and has no direct exposure to European sovereign debt as of the filing of this quarterly report on Form 10-Q.

Redemption Basket Obligation

In order to meet its investment objective and pay its contractual obligations described below, UNL requires liquidity to redeem shares, which redemptions must be in blocks of 50,000 shares called “Redemption Baskets.” UNL 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 shares being redeemed.

Contractual Obligations

UNL’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 UNL’s NAV, currently 0.75% of UNL’s NAV on its average daily total net assets.

USCF agreed to pay the start-up costs associated with the formation of UNL, 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 UNL and its shares with the SEC, FINRA and NYSE Arca (formerly, AMEX), respectively. However, since UNL’s initial offering of shares, offering costs incurred in connection with registering and listing additional shares of UNL have been directly borne on an ongoing basis by UNL, and not by USCF.

30

USCF pays the fees of UNL’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 UNL’s condensed financial statements and its SEC, NFA and CFTC reports. USCF and UNL have also entered into a licensing agreement with the NYMEX pursuant to which UNL and the Related Public Funds, other than BNO, USCI, CPER and USAG, pay a licensing fee to the NYMEX. UNL pays the fees and expenses associated with its tax accounting and reporting requirements. USCF has voluntarily agreed to pay certain expenses normally borne by UNL to the extent that such expenses exceed 0.15% (15 basis points) of UNL’s NAV, on an annualized basis, through at least June 30, 2015. USCF has no obligation to continue such payments into subsequent periods. This voluntary expense waiver is in addition to those amounts USCF is contractually obligated to pay as described in Note 4 in Item 1 of this quarterly report on Form 10-Q.

In addition to USCF’s management fee, UNL pays its brokerage fees (including fees to a FCM), OTC 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 shares, 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 UNL’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. UNL 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 UNL’s per share 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 UNL’s existence. Either party may terminate these agreements earlier for certain reasons described in the agreements.

As of March 31, 2015, UNL’s portfolio consisted of 584 Natural Gas Futures NG Contracts traded on the NYMEX. As of March 31, 2015, UNL did not hold any Natural Gas Futures Contracts traded on ICE Futures. For a list of UNL’s current holdings, please see UNL’s website at www.unitedstatescommodityfunds.com.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

Over-the-Counter Derivatives

UNL may purchase 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.

UNL may enter into certain transactions where an OTC component is exchanged for a corresponding futures contract (“Exchange for Risk” or “EFR transaction”). In the most common type of EFR transaction entered into by UNL, the OTC component is the purchase or sale of one or more baskets of UNL shares. These EFR transactions may expose UNL to counterparty risk during the interim period between the execution of the OTC component and the exchange for a corresponding futures contract. Generally, the counterparty risk from the EFR transaction will exist only on the day of execution.

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 UNL’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, UNL 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 UNL due to the occurrence of a specified event, such as the insolvency of the counterparty.

31

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 UNL 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. UNL 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 three month reporting period ended March 31, 2015, UNL limited its OTC activities to EFR transactions.

UNL anticipates that the use of Other Natural Gas-Related Investments together with its investments in Natural Gas Futures Contracts will produce price and total return results that closely track the investment goals of UNL. 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 Natural Gas Futures Contracts, which may impact UNL’s ability to successfully track the Benchmark Futures Contracts.

Item 4. Controls and Procedures.

Disclosure Controls and Procedures

UNL maintains disclosure controls and procedures that are designed to ensure that material information required to be disclosed in UNL’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 UNL if UNL had any officers, have evaluated the effectiveness of UNL’s disclosure controls and procedures and have concluded that the disclosure controls and procedures of UNL have been effective as of the end of the period covered by this quarterly report on Form 10-Q.
