What is UNL?

The United States 12 Month Natural Gas Fund, LP (“UNL”) is a Delaware limited partnership organized on June 27, 2007. UNL maintains its main business office at 1999 Harrison Street, Suite 1530, Oakland, California 94612. UNL is a commodity pool that issues limited partnership interests (“shares”) traded on the NYSE Arca, Inc. (the “NYSE Arca”). It operates pursuant to the terms of the Second Amended and Restated Agreement of Limited Partnership dated as of March 1, 2013 (as amended from time to time, the “LP Agreement”), which grants full management control to its general partner, United States Commodity Funds LLC (“USCF”).

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 spot 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 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. 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 contract as measured over a time period greater than one day. USCF believes that it is not practical to manage the portfolio to achieve such an investment goal when investing in Futures Contracts (as defined below) and Other Natural Gas-Related Investments (as defined below). UNL’s shares began trading on November 18, 2009. USCF is the general partner of UNL and is responsible for the management of UNL.

Who is USCF?

USCF is a single member limited liability company that was formed in the state of Delaware on May 10, 2005. USCF maintains its main business office at 1999 Harrison Street, Suite 1530, Oakland, California 94612. USCF is a wholly-owned subsidiary of Wainwright Holdings, Inc., a Delaware corporation (“Wainwright”). Mr. Nicholas Gerber (discussed below) controls Wainwright by virtue of his ownership or control of a majority of Wainwright’s shares. Wainwright is a holding company that currently holds shares of both USCF, as well as USCF Advisers LLC, an investment adviser registered under the Investment Advisers Act of 1940, as amended. USCF Advisers LLC serves as the investment adviser for the Stock Split Index Fund, a series of the USCF ETF Trust. USCF ETF Trust is registered under the Investment Company Act of 1940, as amended (the “1940 Act”). The Board of Trustees for the USCF ETF Trust consists of different independent trustees than those independent directors who serve on the Board of Directors of USCF. USCF is a member of the National Futures Association (the “NFA”) and registered as a commodity pool operator (“CPO”) with the Commodity Futures Trading Commission (the “CFTC”) on December 1, 2005 and as a Swaps Firm on August 8, 2013.

USCF also serves as general partner or sponsor of the United States Oil Fund, LP (“USO”), the United States Natural Gas Fund, LP (“UNG”), the United States 12 Month Oil Fund, LP (“USL”), the United States Gasoline Fund, LP (“UGA”), the United States Diesel-Heating Oil Fund, LP (“UHN”), the United States Short Oil Fund, LP (“DNO”), the United States Brent Oil Fund, LP (“BNO”), the United States Commodity Index Fund (“USCI”), the United States Copper Index Fund (“CPER”), the United States Agriculture Index Fund (“USAG”) and the United States Metals Index Fund (“USMI”). USO, UNG, USL, UGA, UHN, DNO, BNO, USCI, CPER, USAG and USMI are actively operating funds and all are listed on the NYSE Arca. On January 30, 2015, USCF as the sponsor of United States Commodity Index Funds Trust (the “Trust”) and its series USMI announced that its officers and members had authorized a plan to (i) liquidate USMI, (ii) terminate the continuous offering of USMI, and (iii) deregister USMI under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and therefore, terminate the Trust’s obligation to include USMI on its periodic and current reports with the Securities and Exchange Commission (“SEC”). USCF has submitted written notice to the NYSE Arca, Inc. (“NYSE Arca”) of its decision to liquidate USMI, terminate the offering and to terminate USMI’s obligations under the Exchange Act.

1

USCF intends to file a post-effective amendment on behalf of the Trust and USMI to terminate the offering of the registered and unsold shares of USMI. The NYSE Arca will file a Form 25 with the SEC to affect the withdrawal of the listing of USMI from the NYSE Arca. Delisting from the NYSE Arca will become effective 10 days after the filing date of the Form 25. Provided that USMI continues to meet the applicable legal requirements, USCF intends to file a Form 15 on behalf of the Trust and USMI with the SEC in early April 2015 to suspend the Trust’s duty to include USMI on its reports under Sections 13(a) and 15(d) of the Exchange Act. USMI expects the termination of registration will become effective 90 days after the date of the filing of the Form 15 with the SEC. All funds listed previously are referred to collectively herein as the “Related Public Funds.” The Related Public Funds are subject to reporting requirements under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). For more information about each of the Related Public Funds, investors in UNL may call 1.800.920.0259 or visit www.unitedstatescommodityfunds.com or the U.S. Securities and Exchange Commission’s (the “SEC”) website at www.sec.gov.

USCF is required to evaluate the credit risk of UNL to the futures commission merchant (“FCM”), oversee the purchase and sale of UNL’s shares by certain authorized purchasers (“Authorized Participants”), review daily positions and margin requirements of UNL and manage UNL’s investments. USCF also pays the fees of ALPS Distributors, Inc., which serves as the marketing agent for UNL (the “Marketing Agent”), and Brown Brothers Harriman & Co. (“BBH&Co.”), which serves as the administrator (the “Administrator”) and the custodian (the “Custodian”) for UNL.

Limited partners have no right to elect USCF as the general partner on an annual or any other continuing basis. If USCF voluntarily withdraws as general partner, however, the holders of a majority of UNL’s outstanding shares (excluding for purposes of such determination shares owned, if any, by the withdrawing USCF and its affiliates) may elect its successor. USCF may not be removed as general partner except upon approval by the affirmative vote of the holders of at least 66 and 2/3 percent of UNL’s outstanding shares (excluding shares owned, if any, by USCF and its affiliates), subject to the satisfaction of certain conditions set forth in the LP Agreement.

The business and affairs of USCF are managed by a board of directors (the “Board”), which is comprised of three management directors (the “Management Directors”), some of whom are also its executive officers, and three independent directors who meet the independent director requirements established by the NYSE Arca Equities Rules and the Sarbanes-Oxley Act of 2002. The Management Directors have the authority to manage USCF pursuant to the terms of the Fifth Amended and Restated Limited Liability Company Agreement of USCF, dated as of July 22, 2011 (as amended from time to time, the “LLC Agreement”). Through its Management Directors, USCF manages the day-to-day operations of UNL. The Board has an audit committee which is made up of the three independent directors (Gordon L. Ellis, Malcolm R. Fobes III and Peter M. Robinson). For additional information relating to the audit committee, please see “Item 10. Directors, Executive Officers and Corporate Governance – Audit Committee” in this annual report on Form 10-K.

How Does UNL Operate?

An investment in the shares provides a means for diversifying an investor’s portfolio or hedging exposure to changes in natural gas prices. An investment in the shares allows both retail and institutional investors to easily gain this exposure to the natural gas market in a transparent, cost-effective manner.

The net assets of UNL consist primarily of investments in futures contracts for natural gas, crude oil, diesel-heating oil, gasoline, and other petroleum-based fuels that are traded on the NYMEX, ICE Futures or other U.S. and foreign exchanges (collectively, “Futures Contracts”) and, to a lesser extent, in order to comply with regulatory requirements or in view of market conditions, other natural gas-related investments such as cash-settled options on Futures Contracts, forward contracts for natural gas, cleared swap contracts and non-exchange traded (“over-the-counter”) transactions that are based on the price of natural gas, oil and other petroleum-based fuels, Futures Contracts 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, Futures Contracts and Other Natural Gas-Related Investments collectively are referred to as “Natural Gas Interests” in this annual report on Form 10-K.

2

UNL invests substantially the entire amount of its assets in Futures Contracts while supporting such investments by holding the amounts of its margin, collateral and other requirements relating to these obligations in short-term obligations of the United States of two years or less (“Treasuries”), cash and cash equivalents. The daily holdings of UNL are available on UNL’s website at www.unitedstatescommodityfunds.com.

The investment objective of UNL is for the daily changes in percentage terms of its shares’ per share NAV to reflect the daily changes in percentage terms of the spot 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 on natural gas traded on the NYMEX, as measured by the changes in the average of the prices of 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 its 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 contract as measured over a time period greater than one day. UNL may invest in interests other than the Benchmark Futures Contracts to comply with accountability levels and position limits. For a detailed discussion of accountability levels and position limits, see “Item 1. Business – What are Futures Contracts?” below in this annual report on Form 10-K.

UNL seeks to achieve its investment objective by investing in a mix of Futures Contracts and Other-Natural-Gas Related Investments such that the changes in its NAV will closely track the changes in the price of the NYMEX Futures Contracts for natural gas delivered to Henry Hub Louisiana. USCF believes changes in the price of the Benchmark Futures Contracts have historically exhibited a close correlation with the changes in the spot price of natural gas. On any valuation day (a valuation day is any NYSE Arca trading day as of which UNL calculates its NAV as described herein), a Benchmark Futures Contract is the near month contract for natural gas traded on the NYMEX unless the near month contract will expire within two weeks of the valuation day, in which case a Benchmark Futures Contract is the next month contract for natural gas on the NYMEX.

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. For example, in cases in which the near month contract’s price is higher than the price of contracts that expire later in time (a situation known as “backwardation” in the futures markets), then absent the impact of the overall movement in natural gas prices the value of the near month contract would tend to rise as it approaches expiration. Conversely, in cases in which the near month contract’s price is lower than the price of contracts that expire later in time (a situation known as “contango” in the futures markets), then absent the impact of the overall movement in natural gas prices the value of the near month contract would tend to decline as it approaches expiration. The total return of a portfolio that owned the near month contract and “rolled” forward each month by selling the near month contract as it approached expiration and purchasing the next month contract to expire would be positively impacted by a backwardation market, and negatively impacted by a contango market. Depending on the exact price relationship of the different month’s prices, portfolio expenses, and the overall movement of natural gas prices, the impact of backwardation and contango could have a major impact on the total return of such a portfolio over time. 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 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.

3

USCF employs a “neutral” investment strategy in order to track changes in the average of the prices of the Benchmark Futures Contracts regardless of whether the price goes up or goes down. UNL’s “neutral” investment strategy is designed to permit investors generally to purchase and sell UNL’s shares for the purpose of investing indirectly in natural gas in a cost-effective manner, and/or to permit participants in the natural gas or other industries to hedge the risk of losses in their natural gas-related transactions. Accordingly, depending on the investment objective of an individual investor, the risks generally associated with investing in natural gas and/or the risks involved in hedging may exist. In addition, an investment in UNL involves the risk that the daily changes in the average of the prices of UNL’s shares, in percentage terms, will not accurately track the daily changes in the Benchmark Futures Contracts, in percentage terms, and that daily changes in the Benchmark Futures Contracts, in percentage terms, will not closely correlate with daily changes in the spot prices of natural gas, in percentage terms.

The Benchmark Futures Contracts are changed from the near month contract to expire and the 11 following months to the next month contract to expire and the 11 following months during one day each month. On that day, USCF anticipates it will “roll” UNL’s positions by closing, or selling, its natural gas interests and reinvests the proceeds from closing these positions in new natural gas interests.

The anticipated monthly dates on which UNL will “roll” its positions are posted on UNL’s website at www.unitedstatescommodityfunds.com, and are subject to change without notice.

UNL’s total portfolio composition is disclosed on its website each business day that the NYSE Arca is open for trading. The website disclosure of portfolio holdings is made daily and includes, as applicable, the name and value of each Natural Gas Interest, the specific types of Natural Gas Interests and characteristics of such Other Natural Gas Interests, the name and value of each Treasury and cash equivalent, and the amount of cash held in UNL’s portfolio. UNL’s website is publicly accessible at no charge. UNL’s assets used for margin and collateral are held in segregated accounts pursuant to the Commodity Exchange Act (the “CEA”) and CFTC regulations.

The shares issued by UNL may only be purchased by Authorized Participants and only in blocks of 50,000 shares called Creation Baskets. The amount of the purchase payment for a Creation Basket is equal to the aggregate NAV of shares in the Creation Basket. Similarly, only Authorized Participants may redeem shares and only in blocks of 50,000 shares called Redemption Baskets. The amount of the redemption proceeds for a Redemption Basket is equal to the aggregate NAV of the shares in the Redemption Basket. The purchase price for Creation Baskets, and the redemption price for Redemption Baskets are the actual NAV calculated at the end of the business day when a request for a purchase or redemption is received by UNL. The NYSE Arca publishes an approximate per share NAV intra-day based on the prior day’s per share NAV and the current price of the Benchmark Futures Contracts, but the price of Creation Baskets and Redemption Baskets is determined based on the actual per share NAV calculated at the end of the day.

While UNL issues shares only in Creation Baskets, shares are listed on the NYSE Arca and investors may purchase and sell shares at market prices like any listed security.

What is UNL’s Investment Strategy?

In managing UNL’s assets, USCF does not use a technical trading system that issues buy and sell orders. USCF instead employs a quantitative methodology whereby each time a Creation Basket is sold, USCF purchases Natural Gas Interests, such as the Benchmark Futures Contracts, that have an aggregate market value that approximates the amount of Treasuries and/or cash received upon the issuance of the Creation Basket.

By remaining invested as fully as possible in Futures Contracts or Other Natural Gas-Related Investments, USCF believes that the daily changes in percentage terms in UNL’s per share NAV will continue to closely track the daily changes in percentage terms in the average of the prices of the Benchmark Futures Contracts. USCF believes that certain arbitrage opportunities result in the price of the shares traded on the NYSE Arca closely tracking the per share NAV of UNL. Additionally, Futures Contracts traded on the NYMEX have closely tracked the spot price of natural gas. Based on these expected interrelationships, USCF believes that the daily changes in the price of UNL’s shares traded on the NYSE Arca, on a percentage basis, have closely tracked and will continue to closely track on a daily basis, the daily changes in the spot price of natural gas, on a percentage basis. For performance data relating to UNL’s ability to track its benchmark, see “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations – Tracking UNL’s Benchmark” in this annual report on Form 10-K.

USCF endeavors to place UNL’s trades in Futures Contracts and Other Natural Gas-Related Investments and otherwise manage UNL’s investments so that “A” will be within plus/minus ten percent (10%) of “B,” where:

| • | A is the average daily change in UNL’s per share NAV for any period of 30 successive valuation days; i.e., any NYSE Arca trading day as of which UNL calculates its per share NAV; and

| • | B is the average daily percentage change in the prices of the Benchmark Futures Contracts over the same period.

USCF believes that market arbitrage opportunities will cause the daily changes in UNL’s share price on the NYSE Arca, on a percentage basis, to closely track the daily changes in UNL’s per share NAV, on a percentage basis. USCF believes that the net effect of these two expected relationships and the relationships described above between UNL’s per share NAV and the Benchmark Futures Contracts will be that the daily changes in the price of UNL’s shares on the NYSE Arca will closely track, in percentage terms, the changes in the spot price of a barrel of natural gas, less UNL’s expenses.

The specific Futures Contracts purchased depend on various factors, including a judgment by USCF as to the appropriate diversification of UNL’s investments in futures contracts with respect to the month of expiration, and the prevailing price volatility of particular contracts. While USCF has made significant investments in NYMEX Futures Contracts, for various reasons, including the ability to enter into the precise amount of exposure to the natural gas market, position limits or other regulatory requirements limiting UNL’s holdings, and market conditions, it may invest in Futures Contracts traded on other exchanges or invest in Other Natural Gas-Related Investments. To the extent that UNL invests in Other Natural Gas-Related Investments, it would prioritize investments in contracts and instruments that are economically equivalent to the Benchmark Futures Contracts, including cleared swaps that satisfy such criteria, and then, to a lesser extent, it would invest in other types of cleared swaps and other contracts, instruments and non-cleared swaps, such as swaps in the over-the-counter market (or commonly referred to as the “OTC market”). If UNL is required by law or regulation, or by one of its regulators, including a futures exchange, to reduce its position in the Futures Contracts to the applicable position limit or to a specified accountability level or if market conditions dictate it would be more appropriate to invest in Other Natural Gas-Related Investments, a substantial portion of UNL’s assets could be invested in accordance with such priority in Other Natural Gas-Related Investments that are intended to replicate the return on the Benchmark Futures Contracts. As UNL’s assets reach higher levels, it is more likely to exceed position limits, accountability levels or other regulatory limits and, as a result, it is more likely that it will invest in accordance with such priority in Other Natural Gas-Related Investments at such higher levels. In addition, 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. See “Item 1. Business – Regulation” in this annual report on Form 10-K for a discussion of the potential impact of regulation on UNL’s ability to invest in over-the-counter transactions and cleared swaps.

USCF may not be able to fully invest UNL’s assets in the Futures Contracts having an aggregate notional amount exactly equal to UNL’s NAV. For example, as standardized contracts, the Futures Contracts are for a specified amount of a particular commodity, and UNL’s NAV and the proceeds from the sale of a Creation Basket are unlikely to be an exact multiple of the amounts of those contracts. As a result, in such circumstances, UNL may be better able to achieve the exact amount of exposure to changes in price of the Benchmark Futures Contracts through the use of Other Natural Gas-Related Investments, such as over-the-counter contracts that have better correlation with changes in price of the Benchmark Futures Contracts.

UNL anticipates that to the extent it invests in Futures Contracts other than contracts on natural gas (such as futures contracts for light, sweet crude oil, diesel-heating oil and other petroleum-based fuels) and Other Natural Gas-Related Investments, it will enter into various non-exchange-traded derivative contracts to hedge the short-term price movements of such Futures Contracts and Other Natural Gas-Related Investments against the current Benchmark Futures Contracts.

USCF does not anticipate letting UNL’s Futures Contracts expire and taking delivery of the underlying commodity. Instead, USCF closes existing positions, e.g., when it changes the Benchmark Futures Contracts or Other Natural Gas-Related Investments or it otherwise determines it would be appropriate to do so and reinvests the proceeds in new Futures Contracts or Other Natural Gas-Related Investments. Positions may also be closed out to meet orders for Redemption Baskets and in such case proceeds for such baskets will not be reinvested.

What is the Natural Gas Market and the Petroleum-Based Fuel Market?

Natural Gas. Natural gas accounts for almost a quarter of U.S. energy consumption. The price of natural gas is established by the supply and demand conditions in the North American market, and more particularly, in the main refining center of the U.S. Gulf Coast. The natural gas market essentially constitutes an auction, where the highest bidder wins the supply. When markets are “strong” (i.e., when demand is high and/or supply is low), the bidder must be willing to pay a higher premium to capture the supply. When markets are “weak” (i.e., when demand is low and/or supply is high), a bidder may choose not to outbid competitors, waiting instead for later, possibly lower priced, supplies. Demand for natural gas by consumers, as well as agricultural, manufacturing and transportation industries, determines overall demand for natural gas. Since the precursors of product demand are linked to economic activity, natural gas demand will tend to reflect economic conditions. However, other factors such as weather significantly influence natural gas demand.

The NYMEX is the world’s largest physical commodity futures exchange and the dominant market for the trading of energy and precious metals. The Benchmark Futures Contracts trade in units of 10,000 million British thermal units (“MMBtu”) and is based on delivery at the Henry Hub in Louisiana, the nexus of 16 intra- and interstate natural gas pipeline systems that draw supplies from the region’s prolific gas deposits. The pipelines serve markets throughout the U.S. East Coast, the Gulf Coast, the Midwest, and up to the Canadian border. Because of the volatility of natural gas prices, a vigorous basis market has developed in the pricing relationships between the Henry Hub and other important natural gas market centers in the continental United States and Canada. The NYMEX makes available for trading a series of basis swap futures contracts that are quoted as price differentials between approximately 30 natural gas pricing points and the Henry Hub. The basis contracts trade in units of 2,500 MMBtu on the New York Mercantile Exchange ClearPort® trading platform. The New York Mercantile Exchange ClearPort® is an electronic trading platform through which a slate of energy futures contracts are available for competitive trading. Transactions can also be consummated off-NYMEX and submitted to the NYMEX for clearing via the NYMEX ClearPort® clearing website as an exchange of futures for physicals or an exchange of futures for swaps transactions.

Light, Sweet Crude Oil. Light, sweet crudes are preferred by refiners because of their low sulfur content and relatively high yields of high-value products such as gasoline, diesel fuel, diesel-heating oil, and jet fuel. The price of light, sweet crude oil has historically exhibited periods of significant volatility.

Demand for petroleum products by consumers, as well as agricultural, manufacturing and transportation industries, determines demand for crude oil by refiners. Since the precursors of product demand are linked to economic activity, crude oil demand will tend to reflect economic conditions. However, other factors such as weather also influence product and crude oil demand.

Crude oil supply is determined by both economic and political factors. Oil prices (along with drilling costs, availability of attractive prospects for drilling, taxes and technology, among other factors) determine exploration and development spending, which influence output capacity with a lag. In the short run, production decisions by the Organization of Petroleum Exporting Countries (“OPEC”) also affect supply and prices. Oil export embargoes and the current conflicts in the Middle East represent other routes through which political developments move the market. It is not possible to predict the aggregate effect of all or any combination of these factors.

Diesel-Heating Oil. Diesel-heating oil, also known as No. 2 fuel oil, accounts for 25% of the yield of a barrel of crude oil, the second largest “cut” from oil after gasoline. The heating oil futures contract listed and traded on the NYMEX trades in units of 42,000 gallons (1,000 barrels) and is based on delivery in the New York harbor, the principal cash market center. The ICE Futures also offers a heating oil futures contract which trades in units of 42,000 U.S. gallons (1,000 barrels). The heating oil futures contract is cash-settled against the prevailing market price for heating oil delivered to the New York Harbor.

Gasoline. Gasoline is the largest single volume refined product sold in the U.S. and accounts for almost half of national oil consumption. The gasoline futures contract listed and traded on the NYMEX trades in units of 42,000 gallons (1,000 barrels) and is based on delivery at petroleum products terminals in the New York harbor, the major East Coast trading center for imports and domestic shipments from refineries in the New York harbor area or from the Gulf Coast refining centers. The price of gasoline has historically been volatile.

What are Futures Contracts?

Futures Contracts are agreements between two parties. One party agrees to buy a commodity such as natural gas from the other party at a later date at a price and quantity agreed upon when the contract is made. Futures Contracts are traded on futures exchanges, including the NYMEX. For example, the Benchmark Futures Contracts are traded on the NYMEX in units of 10,000 MMBtu. Futures Contracts traded on the NYMEX are priced by floor brokers and other exchange members both through an “open outcry” of offers to purchase or sell the contracts and through an electronic, screen-based system that determines the price by matching electronically offers to purchase and sell. Additional risks of investing in Futures Contracts are included in “Item 1A. Risk Factors” in this annual report on Form 10-K.

Impact of Accountability Levels, Position Limits and Price Fluctuation Limits. Futures contracts include typical and significant characteristics. Most significantly, the CFTC and U.S. designated contract markets such as the NYMEX 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 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 Futures Contracts traded on U.S.-based futures exchanges, such as the NYMEX, are not a fixed ceiling, but rather a threshold above which the NYMEX may exercise greater scrutiny and control over an investor’s positions. The current accountability level for investments for any one-month in a Benchmark Futures Contract is 6,000 net contracts. In addition, the NYMEX imposes an accountability level for all months of 12,000 net futures contracts for natural gas. In addition, the ICE Futures maintains the same accountability levels, position limits and monitoring authority for its natural gas contract as the NYMEX. If UNL and the Related Public Funds exceed these accountability levels for investments in the futures contract for natural gas, the NYMEX and ICE Futures will monitor such exposure and may ask for further information on their activities, including the total size of all positions, investment and trading strategy, and the extent of liquidity resources of UNL and the Related Public Funds. If deemed necessary by the NYMEX and/or ICE Futures, UNL could be ordered to reduce its aggregate position back to the accountability level. As of December 31, 2014, UNL held 537 Natural Gas NG Futures Contracts traded on the NYMEX and did not hold any Futures Contracts traded on ICE Futures. For the year ended December 31, 2014, 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 contracts to expire to the next month contracts during a one-day period beginning two weeks from expiration of the contracts. For the year ended December 31, 2014, UNL did not exceed any position limits imposed by the NYMEX and ICE Futures.

7

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: over-the-counter, DCMs, SEFs as well as non-U.S. located platforms. Furthermore, 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 over-the-counter 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 ten percent (10%) 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 “The Commodity Interest Markets – Regulation” in this annual report on Form 10-K for additional information.

Price Volatility. The price volatility of Futures Contracts generally has been historically greater than that for traditional securities such as stocks and bonds. Price volatility often is greater day-to-day as opposed to intra-day. Futures Contracts tend to be more volatile than stocks and bonds because price movements for natural gas are more currently and directly influenced by economic factors for which current data is available and are traded by natural gas futures traders throughout the day. Because UNL invests a significant portion of its assets in Futures Contracts, the assets of UNL, and therefore the prices of UNL shares, may be subject to greater volatility than traditional securities.

Marking-to-Market Futures Positions. Futures Contracts are marked to market at the end of each trading day and the margin required with respect to such contracts is adjusted accordingly. This process of marking-to-market is designed to prevent losses from accumulating in any futures account. Therefore, if UNL’s futures positions have declined in value, UNL may be required to post “variation margin” to cover this decline. Alternatively, if UNL’s futures positions have increased in value, this increase will be credited to UNL’s account.

Why Does UNL Purchase and Sell Futures Contracts?

UNL’s investment objective is for the daily changes in percentage terms of its shares’ per share NAV to reflect the daily changes in percentage terms of the spot price of natural gas delivered at the Henry Hub, Louisiana, as measured by the changes in the average of the prices of 12 futures contracts on natural gas traded on 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, less UNL’s expenses. When calculating the daily movement of the average price of the 12 Benchmark Futures Contracts, each contract month is equally weighted.

In connection with investing in Futures Contracts and Other Natural Gas-Related Investments, UNL holds Treasuries, cash and/or cash equivalents that serve as segregated assets supporting UNL’s positions in Futures Contracts and Other Natural Gas-Related Investments. For example, the purchase of a Futures Contract with a stated value of $10 million would not require UNL to pay $10 million upon entering into the contract; rather, only a margin deposit, generally of 5% to 30% of the stated value of the Futures Contract, would be required. To secure its Futures Contract obligations, UNL would deposit the required margin with the FCM and would separately hold, through its Custodian or FCM, Treasuries, cash and/or cash equivalents in an amount equal to the balance of the current market value of the contract, which at the contract’s inception would be $10 million minus the amount of the margin deposit, or $9.5 million (assuming a 5% margin).

8

As a result of the foregoing, typically 5% to 30% of UNL’s assets are held as margin in segregated accounts with a FCM. In addition to the Treasuries and cash it posts with the FCM for the Futures Contracts it owns, UNL may hold, through the Custodian, Treasuries, cash and/or cash equivalents that can be posted as additional margin or as other collateral to support its over-the-counter contracts. UNL earns income from the Treasuries and/or cash equivalents that it purchases, and on the cash it holds through the Custodian or FCM. UNL anticipates that the earned income will increase the NAV and limited partners’ capital contribution accounts. UNL reinvests the earned income, holds it in cash, or uses it to pay its expenses. If UNL reinvests the earned income, it makes investments that are consistent with its investment objective.

What are the Trading Policies of UNL?

Liquidity

UNL invests only in Futures Contracts and Other Natural Gas-Related Investments that, in the opinion of USCF, are traded in sufficient volume to permit the ready taking and liquidation of positions in these financial interests and Other Natural Gas-Related Investments that, in the opinion of USCF, may be readily liquidated with the original counterparty or through a third party assuming the position of UNL.

Spot Commodities

While the Futures Contracts can be physically settled, UNL does not intend to take or make physical delivery. UNL may from time to time trade in Other Natural Gas-Related Investments, including contracts based on the spot price of natural gas.

Leverage

USCF endeavors to have the value of UNL’s Treasuries, cash and cash equivalents, whether held by UNL or posted as margin or other collateral, at all times approximate the aggregate market value of its obligations under its Futures Contracts and Other Natural Gas-Related Investments. Commodity pools’ trading positions in futures contracts or other related investments are typically required to be secured by the deposit of margin funds that represent only a small percentage of a futures contract’s (or other commodity interest’s) entire market value. While USCF has not and does not intend to leverage UNL’s assets, it is not prohibited from doing so under the LP Agreement.

Borrowings

Borrowings are not used by UNL, unless UNL is required to borrow money in the event of physical delivery, if UNL trades in cash commodities, or for short-term needs created by unexpected redemptions.

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

In addition to Futures Contracts, there are also a number of listed options on the Futures Contracts on the principal futures exchanges. These contracts offer investors and hedgers another set of financial vehicles to use in managing exposure to the natural gas market. Consequently, UNL may purchase options on natural gas Futures Contracts on these exchanges in pursuing its investment objective.

In addition to the Futures Contracts and options on the Futures Contracts, there also exists an active non-exchange-traded market in derivatives tied to natural gas. These derivatives transactions (also known as over-the-counter contracts) are usually entered into between two parties in private contracts. Unlike most of the exchange-traded Futures Contracts or exchange-traded options on the Futures Contracts, each party to such contract bears the credit risk of the other party, i.e., the risk that the other party may not be able to perform its obligations under its contract.

9

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, Inc. (“ISDA”) that provides for the netting of its overall exposure to its counterparty.

USCF assesses or reviews, as appropriate, the creditworthiness of each potential or existing counterparty to an over-the-counter contract pursuant to guidelines approved by USCF’s Board.

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

UNL may employ spreads or straddles in its trading to mitigate the differences in its investment portfolio and its goal of tracking the price of the Benchmark Futures Contract. UNL would use a spread when it chooses to take simultaneous long and short positions in futures written on the same underlying asset, but with different delivery months.

During the reporting period of this annual report on Form 10-K, UNL limited its derivatives activities to Futures Contracts and EFRP transactions.

Pyramiding

UNL has not and will not employ the technique, commonly known as pyramiding, in which the speculator uses unrealized profits on existing positions as variation margin for the purchase or sale of additional positions in the same or another commodity interest.

Who are the Service Providers?

In its capacity as the Custodian for UNL, BBH&Co. may hold UNL’s Treasuries, cash and/or cash equivalents pursuant to a custodial agreement. BBH&Co. is also the registrar and transfer agent for the shares. In addition, in its capacity as Administrator for UNL, BBH&Co. performs certain administrative and accounting services for UNL and prepares certain SEC, NFA and CFTC reports on behalf of UNL. USCF pays BBH&Co.’s fees for these services.

BBH&Co.’s principal business address is 50 Post Office Square, Boston, MA 02110-1548. BBH&Co., a private bank founded in 1818, is neither a publicly held company nor insured by the Federal Deposit Insurance Corporation. BBH&Co. is authorized to conduct a commercial banking business in accordance with the provisions of Article IV of the New York State Banking Law, New York Banking Law §§160–181, and is subject to regulation, supervision, and examination by the New York State Department of Financial Services. BBH&Co. is also licensed to conduct a commercial banking business by the Commonwealths of Massachusetts and Pennsylvania and is subject to supervision and examination by the banking supervisors of those states.

UNL also employs ALPS Distributors, Inc. as its marketing agent (the “Marketing Agent” or “ALPS Distributors”). USCF pays the Marketing Agent an annual fee. In no event may the aggregate compensation paid to the Marketing Agent and any affiliate of USCF for distribution-related services in connection with the offering of shares exceed ten percent (10%) of the gross proceeds of the offering.

ALPS Distributors’ principal business address is 1290 Broadway, Suite 1100, Denver, CO 80203. ALPS Distributors is the marketing agent for UNL. ALPS Distributors is a broker-dealer registered with the Financial Industry Regulatory Authority (“FINRA”) and a member of the Securities Investor Protection Corporation.

On October 8, 2013, USCF entered into a Futures and Cleared Derivatives Transactions Customer Account 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, UBS Securities LLC (“UBS Securities”) was UNL’s FCM. This agreement requires RBC Capital to provide services to UNL, as of October 10, 2013, in connection with the purchase and sale of Futures Contracts and Other Natural Gas-Related Investments that may be purchased or sold by or through RBC Capital for UNL’s account. For the period October 10, 2013 and after, UNL pays RBC Capital commissions for executing and clearing trades on behalf of UNL. Prior to October 10, 2013, UNL paid UBS Securities commissions for executing and clearing trades on behalf of UNL.

RBC Capital’s primary address is 500 West Madison Street, Suite 2500, Chicago, Illinois 60661. UBS Securities’ principal business address is 677 Washington Blvd., Stamford, Connecticut 06901. From UNL’s commencement of trading to October 10, 2013, UBS Securities was a futures clearing broker for UNL. Effective October 10, 2013, RBC Capital became the futures clearing broker for UNL. Both RBC Capital and UBS Securities are registered in the United States with FINRA as a broker-dealer and with the CFTC as a FCM. RBC Capital and UBS Securities are members of various U.S. futures and securities exchanges.

RBC is a large broker-dealer subject to many different complex legal and regulatory requirements. As a result, certain of RBC’s regulators may from time to time conduct investigations, initiate enforcement proceedings and/or enter into settlements with RBC with respect to issues raised in various investigations. RBC complies fully with its regulators in all investigations being conducted and in all settlements it reaches. In addition, RBC is and has been subject to a variety of civil legal claims in various jurisdictions, a variety of settlement agreements and a variety of orders, awards and judgments made against it by courts and tribunals, both in regard to such claims and investigations. RBC complies fully with all settlements it reaches and all orders, awards and judgments made against it.

RBC has been named as a defendant in various legal actions, including arbitrations, class actions and other litigation including those described below, arising in connection with its activities as a broker-dealer. Certain of the actual or threatened legal actions include claims for substantial compensatory and/or punitive damages or claims for indeterminate amounts of damages. RBC is also involved, in other reviews, investigations and proceedings (both formal and informal) by governmental and self-regulatory agencies regarding RBC's business, including among other matters, accounting and operational matters, certain of which may result in adverse judgments, settlements, fines, penalties, injunctions or other relief.

RBC contests liability and/or the amount of damages as appropriate in each pending matter. In view of the inherent difficulty of predicting the outcome of such matters, particularly in cases where claimants seek substantial or indeterminate damages or where investigations and proceedings are in the early stages, RBC cannot predict the loss or range of loss, if any, related to such matters; how or if such matters will be resolved; when they will ultimately be resolved; or what the eventual settlement, fine, penalty or other relief, if any, might be. Subject to the foregoing, RBC believes, based on current knowledge and after consultation with counsel, that the outcome of such pending matters will not have a material adverse effect on the consolidated financial condition of RBC.

On March 11, 2013, the New Jersey Bureau of Securities entered a consent order settling an administrative complaint against RBC, which alleged that RBC failed to follow its own procedures with respect to monthly account reviews and failed to maintain copies of the monthly account reviews with respect to certain accounts that James Hankins Jr. maintained at the firm in violation of N.J.S.A. 49:3-58(a)(2)(xi) and 49:3-59(b). Without admitting or denying the findings of fact and conclusions of law, RBC consented to a civil monetary penalty of $150,000 (of which $100,000 was suspended as a result of the firm’s cooperation) and to pay disgorgement of $300,000.

On June 12, 2012, the State of Illinois Secretary of State Securities Department consented to entry of a judgment enjoining the firm for violation of the Illinois Securities Law of 1953. RBC undertook to repurchase auction rate securities from certain customers before June 30, 2009. RBC also undertook to use best efforts to provide, by December 31, 2009, liquidity opportunities for customers ineligible for the buyback. RBC undertook to provide periodic reports to regulator. RBC paid a penalty of $1,400,139.82.

On May 10, 2012, FINRA commenced and settled an administrative proceeding against RBC for violations of FINRA Rules 1122 and 2010 and NASD Rules 2110 and 3010 for failing to establish, maintain and enforce written supervisory procedures reasonably designed to achieve compliance with applicable rules concerning short-term transactions in closed end funds. RBC paid a fine of $200,000.

11

On May 2, 2012, the Massachusetts Securities Division entered a consent order settling an administrative complaint against RBC, which alleged that RBC recommended unsuitable products to its brokerage and advisory clients and failed to supervise its registered representatives’ sales of inverse and leveraged ETFs in violation of Section 204(a)(2) of the Massachusetts Uniform Securities Act ("MUSA"). Without admitting or denying the allegations of fact, RBC consented to permanently cease and desist from violations of MUSA, pay restitution of $2.9 million to the investors who purchased the inverse and leveraged ETFs and pay a civil monetary penalty of $250,000.

On September 27, 2011, the SEC commenced and settled an administrative proceeding against RBC for wilful violations of Sections 17(a)(2) and 17(a)(3) of the 1933 Act for negligently selling the collateralized debt obligations to five Wisconsin school districts despite concerns about the suitability of the product. The firm agreed to pay disgorgement of $6.6 million, prejudgment interest of $1.8 million, and a civil monetary penalty of $22 million.

For more details, please see RBC’s Form BD, as filed with the SEC.

RBC Capital will act only as clearing broker for UNL and as such will be paid commissions for executing and clearing trades on behalf of UNL. Prior to October 10, 2013, UBS Securities acted only as clearing broker for UNL and as such was paid commissions for executing and clearing trades on behalf of UNL. RBC Capital has not passed upon the adequacy or accuracy of this annual report on Form 10-K. RBC Capital will not act in any supervisory capacity with respect to USCF or participate in the management of USCF or UNL.

RBC Capital is not affiliated with UNL or USCF. Therefore, neither USCF nor UNL believes that there are any conflicts of interest with RBC Capital or its trading principals arising from its acting as UNL’s FCM.

Currently, USCF does not employ commodity trading advisors for the trading of UNL contracts. USCF currently does, however, employ SummerHaven Investment Management, LLC as a trading advisor for CPER, USAG, USCI and USMI. If, in the future, USCF does employ commodity trading advisors for UNL, it will choose each advisor based on arm’s-length negotiations and will consider the advisor’s experience, fees and reputation.

Form of Shares

Registered Form. Shares are issued in registered form in accordance with the LP Agreement. The Administrator has been appointed registrar and transfer agent for the purpose of transferring shares in certificated form. The Administrator keeps a record of all limited partners and holders of the shares in certificated form in the registry (the “Register”). USCF recognizes transfers of shares in certificated form only if done in accordance with the LP Agreement. The beneficial interests in such shares are held in book-entry form through participants and/or accountholders in the Depository Trust Company (“DTC”).

Book Entry. Individual certificates are not issued for the shares. Instead, shares are represented by one or more global certificates, which are deposited by the Administrator with DTC and registered in the name of Cede & Co., as nominee for DTC. The global certificates evidence all of the shares outstanding at any time. Shareholders are limited to (1) participants in DTC such as banks, brokers, dealers and trust companies (“DTC Participants”), (2) those who maintain, either directly or indirectly, a custodial relationship with a DTC Participant (“Indirect Participants”), and (3) those banks, brokers, dealers, trust companies and others who hold interests in the shares through DTC Participants or Indirect Participants, in each case who satisfy the requirements for transfers of shares. DTC Participants acting on behalf of investors holding shares through such participants’ accounts in DTC will follow the delivery practice applicable to securities eligible for DTC’s Same-Day Funds Settlement System. Shares are credited to DTC Participants’ securities accounts following confirmation of receipt of payment.

DTC. DTC has advised UNL as follows: It is a limited purpose trust company organized under the laws of the State of New York and is a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code and a “clearing agency” registered pursuant to the provisions of Section 17A of the Exchange Act. DTC holds securities for DTC Participants and facilitates the clearance and settlement of transactions between DTC Participants through electronic book-entry changes in accounts of DTC Participants.

Calculating Per Share NAV

UNL’s per share NAV is calculated by:

• | Taking the current market value of its total assets;
• | Subtracting any liabilities; and
• | Dividing that total by the total number of outstanding shares.

The Administrator, calculates the per share NAV of UNL once each NYSE Arca trading day. The per share NAV for a normal 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. The 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 Futures Contracts traded on the NYMEX, but calculates or determines the value of all other UNL investments (including Futures Contracts not traded on the NYMEX, Other Natural Gas-Related Investments and Treasuries) using market quotations, if available, or other information customarily used to determine the fair value of such investments as of the earlier of the close of the NYSE Arca or 4:00 p.m. New York time in accordance with the current Administrative Agency Agreement among BBH&Co., UNL and USCF. “Other information” customarily used in determining fair value includes information consisting of market data in the relevant market supplied by one or more third parties including, without limitation, relevant rates, prices, yields, yield curves, volatilities, spreads, correlations or other market data in the relevant market; or information of the types described above from internal sources if that information is of the same type used by UNL in the regular course of its business for the valuation of similar transactions. The information may include costs of funding, to the extent costs of funding are not and would not be a component of the other information being utilized. Third parties supplying quotations or market data may include, without limitation, dealers in the relevant markets, end-users of the relevant product, information vendors, brokers and other sources of market information.

14

In addition, in order to provide updated information relating to UNL for use by investors and market professionals, the NYSE Arca calculates and disseminates throughout the core trading session on each trading day an updated indicative fund value. The indicative fund value is calculated by using the prior day’s closing per share NAV of UNL as a base and updating that value throughout the trading day to reflect changes in the most recently reported trade price for the active natural gas Futures Contracts on the NYMEX. The prices reported for those Futures Contract months are adjusted based on the prior day’s spread differential between settlement values for the relevant contract and the spot month contract. In the event that the spot month contract is also the Benchmark Futures Contracts, the last sale price for that contract is not adjusted. The indicative fund value share basis disseminated during NYSE Arca core trading session hours should not be viewed as an actual real time update of the per share NAV, because the per share NAV is calculated only once at the end of each trading day based upon the relevant end of day values of UNL’s investments.

The indicative fund value is disseminated on a per share basis every 15 seconds during regular NYSE Arca core trading session hours of 9:30 a.m. New York time to 4:00 p.m. New York time. The normal trading hours of the NYMEX are 10:00 a.m. New York time to 2:30 p.m. New York time. This means that there is a gap in time at the beginning and the end of each day during which UNL’s shares are traded on the NYSE Arca, but real-time NYMEX trading prices for Futures Contracts traded on the NYMEX are not available. During such gaps in time, the indicative fund value will be calculated based on the end of day price of such Futures Contracts from the NYMEX’s immediately preceding trading session. In addition, other Futures Contracts, Other Natural Gas-Related Investments and Treasuries held by UNL will be valued by the Administrator, using rates and points received from client-approved third party vendors (such as Reuters and WM Company) and advisor quotes. These investments will not be included in the indicative fund value.

Dissemination of the indicative fund value provides additional information that is not otherwise available to the public and is useful to investors and market professionals in connection with the trading of UNL shares on the NYSE Arca. Investors and market professionals are able throughout the trading day to compare the market price of UNL and the indicative fund value. If the market price of UNL shares diverges significantly from the indicative fund value, market professionals will have an incentive to execute arbitrage trades. For example, if UNL appears to be trading at a discount compared to the indicative fund value, a market professional could buy UNL shares on the NYSE Arca and sell short Futures Contracts. Such arbitrage trades can tighten the tracking between the market price of UNL and the indicative fund value and thus can be beneficial to all market participants.

Creation and Redemption of Shares

UNL creates and redeems shares from time to time, but only in one or more Creation Baskets or Redemption Baskets. The creation and redemption of baskets are only made in exchange for delivery to UNL or the distribution by UNL of the amount of Treasuries and any cash represented by the baskets being created or redeemed, the amount of which is based on the combined NAV of the number of shares included in the baskets being created or redeemed determined after 4:00 p.m. New York time on the day the order to create or redeem baskets is properly received.

Authorized Participants are the only persons that may place orders to create and redeem baskets. Authorized Participants must be (1) registered broker-dealers or other securities market participants, such as banks and other financial institutions, that are not required to register as broker-dealers to engage in securities transactions as described below, and (2) DTC Participants. To become an Authorized Participant, a person must enter into an Authorized Participant Agreement with USCF on behalf of UNL. The Authorized Participant Agreement provides the procedures for the creation and redemption of baskets and for the delivery of the Treasuries and any cash required for such creations and redemptions. The Authorized Participant Agreement and the related procedures attached thereto may be amended by UNL, without the consent of any limited partner or shareholder or Authorized Participant. From July 1, 2011 through December 31, 2014 (and continuing at least through April 30, 2015), the applicable transaction fee paid by Authorized Participants is $350 for each order placed to create or redeem one or more baskets; prior to July 1, 2011, this fee was $1,000. Authorized Participants who make deposits with UNL in exchange for baskets receive no fees, commissions or other form of compensation or inducement of any kind from either UNL or USCF, and no such person will have any obligation or responsibility to USCF or UNL to effect any sale or resale of shares. As of December 31, 2014, 10 Authorized Participants had entered into agreements with USCF on behalf of UNL. During the year ended December 31, 2014, UNL issued 6 Creation Baskets and redeemed 12 Redemption Baskets.

15

Certain Authorized Participants are expected to be capable of participating directly in the physical natural gas market and the natural gas futures market. In some cases, Authorized Participants or their affiliates may from time to time buy natural gas or sell natural gas or Natural Gas Interests and may profit in these instances. USCF believes that the size and operation of the natural gas market make it unlikely that an Authorized Participant’s direct activities in the natural gas or securities markets will significantly affect the price of natural gas, Natural Gas Interests, or the price of the shares.

Each Authorized Participant is required to be registered as a broker-dealer under the Exchange Act and is a member in good standing with FINRA, or exempt from being or otherwise not required to be registered as a broker-dealer or a member of FINRA, and qualified to act as a broker or dealer in the states or other jurisdictions where the nature of its business so requires. Certain Authorized Participants may also be regulated under federal and state banking laws and regulations. Each Authorized Participant has its own set of rules and procedures, internal controls and information barriers as it determines is appropriate in light of its own regulatory regime.

Under the Authorized Participant Agreement, USCF, and UNL under limited circumstances, have agreed to indemnify the Authorized Participants against certain liabilities, including liabilities under the 1933 Act, and to contribute to the payments the Authorized Participants may be required to make in respect of those liabilities.

The following description of the procedures for the creation and redemption of baskets is only a summary and an investor should refer to the relevant provisions of the LP Agreement and the form of Authorized Participant Agreement for more detail, each of which is incorporated by reference into this annual report on Form 10-K.

Creation Procedures

On any business day, an Authorized Participant may place an order with the Marketing Agent to create one or more baskets. For purposes of processing purchase and redemption orders, a “business day” means any day other than a day when any of the NYSE Arca, the NYMEX or the NYSE is closed for regular trading. Purchase orders must be placed by 12:00 p.m. New York time or the close of regular trading on the NYSE Arca, whichever is earlier. The day on which the Marketing Agent receives a valid purchase order is referred to as the purchase order date.

By placing a purchase order, an Authorized Participant agrees to deposit Treasuries, cash, or a combination of Treasuries and cash, as described below. Prior to the delivery of baskets for a purchase order, the Authorized Participant must also have wired to the Custodian the non-refundable transaction fee due for the purchase order. Authorized Participants may not withdraw a creation request.

The manner by which creations are made is dictated by the terms of the Authorized Participant Agreement. By placing a purchase order, an Authorized Participant agrees to (1) deposit Treasuries, cash or a combination of Treasuries and cash with the Custodian, and (2) if required by USCF in its sole discretion, enter into or arrange for a block trade, an exchange for physical or exchange for swap, or any other over-the-counter energy transaction (through itself or a designated acceptable broker) with UNL for the purchase of a number and type of futures contracts at the closing settlement price for such contracts on the purchase order date. If an Authorized Participant fails to consummate (1) and (2), the order shall be cancelled. The number and type of contracts specified shall be determined by USCF, in its sole discretion, to meet UNL’s investment objective and shall be purchased as a result of the Authorized Participant’s purchase of shares.

Determination of Required Deposits

The total deposit required to create each basket (“Creation Basket Deposit”) is the amount of Treasuries and/or cash that is in the same proportion to the total assets of UNL (net of estimated accrued but unpaid fees, expenses and other liabilities) on the purchase order date as the number of shares to be created under the purchase order is in proportion to the total number of shares outstanding on the purchase order dates. USCF determines, directly in its sole discretion or in consultation with the Administrator, the requirements for Treasuries and the amount of cash, including the maximum permitted remaining maturity of a Treasury and proportions of Treasury and cash that may be included in deposits to create baskets. The Marketing Agent will publish such requirements at the beginning of each business day. The amount of cash deposit required is the difference between the aggregate market value of the Treasuries required to be included in a Creation Basket Deposit as of 4:00 p.m. New York time on the date the order to purchase is properly received and the total required deposit.

16

Delivery of Required Deposits

An Authorized Participant who places a purchase order is responsible for transferring to UNL’s account with the Custodian the required amount of Treasuries and cash by the end of the third business day following the purchase order date. Upon receipt of the deposit amount, the Administrator directs DTC to credit the number of baskets ordered to the Authorized Participant’s DTC account on the third business day following the purchase order date. The expense and risk of delivery and ownership of Treasuries until such Treasuries have been received by the Custodian on behalf of UNL shall be borne solely by the Authorized Participant.

Because orders to purchase baskets must be placed by 12:00 p.m., New York time, but the total payment required to create a basket during the continuous offering period will not be determined until after 4:00 p.m. New York time on the date the purchase order is received, Authorized Participants will not know the total amount of the payment required to create a basket at the time they submit an irrevocable purchase order for the basket. UNL’s per share NAV and the total amount of the payment required to create a basket could rise or fall substantially between the time an irrevocable purchase order is submitted and the time the amount of the purchase price in respect thereof is determined.

Rejection of Purchase Orders

USCF acting by itself or through the Marketing Agent shall have the absolute right but no obligation to reject a purchase order or a Creation Basket Deposit if:

• | it determines that the investment alternative available to UNL at that time will not enable it to meet its investment objective;
• | it determines that the purchase order or the Creation Basket Deposit is not in proper form;
• | it believes that the purchase order or the Creation Basket Deposit would have adverse tax consequences to UNL, the limited partners or its shareholders;
• | the acceptance or receipt of the Creation Basket Deposit would, in the opinion of counsel to USCF, be unlawful; or
• | circumstances outside the control of USCF, Marketing Agent or Custodian make it, for all practical purposes, not feasible to process creations of baskets.

None of USCF, the Marketing Agent or the Custodian will be liable for the rejection of any purchase order or Creation Basket Deposit.

Redemption Procedures

The procedures by which an Authorized Participant can redeem one or more baskets mirror the procedures for the creation of baskets. On any business day, an Authorized Participant may place an order with the Marketing Agent to redeem one or more baskets. Redemption orders must be placed by 12:00 p.m. New York time or the close of regular trading on the NYSE Arca, whichever is earlier. A redemption order so received will be effective on the date it is received in satisfactory form by the Marketing Agent (“Redemption Order Date”). The redemption procedures allow Authorized Participants to redeem baskets and do not entitle an individual shareholder to redeem any shares in an amount less than a Redemption Basket, or to redeem baskets other than through an Authorized Participant.

By placing a redemption order, an Authorized Participant agrees to deliver the baskets to be redeemed through DTC’s book-entry system to UNL, as described below. Prior to the delivery of the redemption distribution for a redemption order, the Authorized Participant must also have wired to UNL’s account at the Custodian the non-refundable transaction fee due for the redemption order. An Authorized Participant may not withdraw a redemption order.

17

The manner by which redemptions are made is dictated by the terms of the Authorized Participant Agreement. By placing a redemption order, an Authorized Participant agrees to (1) deliver the Redemption Basket to be redeemed through DTC’s book-entry system to UNL’s account with the Custodian not later than 3:00 p.m. New York time on the third business day following the effective date of the redemption order (“Redemption Distribution Date”), and (2) if required by USCF in its sole discretion, enter into or arrange for a block trade, an exchange for physical or exchange for swap, or any other over-the-counter energy transaction (through itself or a designated acceptable broker) with UNL for the sale of a number and type of futures contracts at the closing settlement price for such contracts on the Redemption Order Date. If an Authorized Participant fails to consummate (1) and (2) above, the order shall be cancelled. The number and type of contracts specified shall be determined by USCF, in its sole discretion, to meet UNL’s investment objective and shall be sold as a result of the Authorized Participant’s sale of shares.

Determination of Redemption Distribution

The redemption distribution from UNL consists of a transfer to the redeeming Authorized Participant of an amount of Treasuries and/or cash that is in the same proportion to the total assets of UNL (net of estimated accrued but unpaid fees, expenses and other liabilities) on the date the order to redeem is properly received as the number of shares to be redeemed under the redemption order is in proportion to the total number of shares outstanding on the date the order is received. USCF, directly or in consultation with the Administrator, determines the requirements for Treasuries and the amounts of cash, including the maximum permitted remaining maturity of a Treasury, and the proportions of Treasuries and cash that may be included in distributions to redeem baskets. The Marketing Agent will publish an estimate of the redemption distribution per basket as of the beginning of each business day.

Delivery of Redemption Distribution

The redemption distribution due from UNL will be delivered to the Authorized Participant by 3:00 p.m. New York time on the third business day following the redemption order date if, by 3:00 p.m. New York time on such third business day, UNL’s DTC account has been credited with the baskets to be redeemed. If UNL’s DTC account has not been credited with all of the baskets to be redeemed by such time, the redemption distribution will be delivered to the extent of whole baskets received. Any remainder of the redemption distribution will be delivered on the next business day to the extent of remaining whole baskets received if UNL receives the fee applicable to the extension of the redemption distribution date which USCF may, from time to time, determine and the remaining baskets to be redeemed are credited to UNL’s DTC account by 3:00 p.m. New York time on such next business day. Any further outstanding amount of the redemption order shall be cancelled. Pursuant to information from USCF, the Custodian will also be authorized to deliver the redemption distribution notwithstanding that the baskets to be redeemed are not credited to UNL’s DTC account by 3:00 p.m. New York time on the third business day following the redemption order date if the Authorized Participant has collateralized its obligation to deliver the baskets through DTC’s book entry-system on such terms as USCF may from time to time determine.

Suspension or Rejection of Redemption Orders

USCF may, in its discretion, suspend the right of redemption, or postpone the redemption settlement date, (1) for any period during which the NYSE Arca or the NYMEX is closed other than customary weekend or holiday closings, or trading on the NYSE Arca or the NYMEX is suspended or restricted, (2) for any period during which an emergency exists as a result of which delivery, disposal or evaluation of Treasuries is not reasonably practicable, or (3) for such other period as USCF determines to be necessary for the protection of the limited partners or shareholders. For example, USCF may determine that it is necessary to suspend redemptions to allow for the orderly liquidation of UNL’s assets at an appropriate value to fund a redemption. If USCF has difficulty liquidating its positions, e.g., because of a market disruption event in the futures markets, a suspension of trading by the exchange where the futures contracts are listed or an unanticipated delay in the liquidation of a position in an over-the-counter contract, it may be appropriate to suspend redemptions until such time as such circumstances are rectified. None of USCF, the Marketing Agent, the Administrator, or the Custodian will be liable to any person or in any way for any loss or damages that may result from any such suspension or postponement.

18

Redemption orders must be made in whole baskets. USCF will reject a redemption order if the order is not in proper form as described in the Authorized Participant Agreement or if the fulfillment of the order, in the opinion of its counsel, might be unlawful. USCF may also reject a redemption order if the number of shares being redeemed would reduce the remaining outstanding shares to 100,000 shares (i.e., two baskets) or less.

Creation and Redemption Transaction Fee

To compensate UNL for its expenses in connection with the creation and redemption of baskets, an Authorized Participant is required to pay a transaction fee to UNL per order to create or redeem baskets, regardless of the number of baskets in such order. From July 1, 2011 through December 31, 2014 (and continuing at least through April 30, 2015), the applicable transaction fee paid by Authorized Participants is $350 for each order they placed to create or redeem one or more baskets; prior to July 1, 2011, this fee was $1,000. The transaction fee may be reduced, increased or otherwise changed by USCF. USCF shall notify DTC of any change in the transaction fee and will not implement any increase in the fee for the redemption of baskets until 30 days after the date of the notice.

Tax Responsibility

Authorized Participants are responsible for any transfer tax, sales or use tax, stamp tax, recording tax, value added tax or similar tax or governmental charge applicable to the creation or redemption of baskets, regardless of whether or not such tax or charge is imposed directly on the Authorized Participant, and agree to indemnify USCF and UNL if they are required by law to pay any such tax, together with any applicable penalties, additions to tax and interest thereon.

Secondary Market Transactions

As noted, UNL creates and redeems shares from time to time, but only in one or more Creation Baskets or Redemption Baskets. The creation and redemption of baskets are only made in exchange for delivery to UNL or the distribution by UNL of the amount of Treasuries and cash represented by the baskets being created or redeemed, the amount of which will be based on the aggregate NAV of the number of shares included in the baskets being created or redeemed determined on the day the order to create or redeem baskets is properly received.

As discussed above, Authorized Participants are the only persons that may place orders to create and redeem baskets. Authorized Participants must be registered broker-dealers or other securities market participants, such as banks and other financial institutions that are not required to register as broker-dealers to engage in securities transactions. An Authorized Participant is under no obligation to create or redeem baskets, and an Authorized Participant is under no obligation to offer to the public shares of any baskets it does create. Authorized Participants that do offer to the public shares from the baskets they create will do so at per-share offering prices that are expected to reflect, among other factors, the trading price of the shares on the NYSE Arca, the NAV of UNL at the time the Authorized Participant purchased the Creation Baskets and the per share NAV of the shares at the time of the offer of the shares to the public, the supply of and demand for shares at the time of sale, and the liquidity of the Futures Contract market and the market for Other Natural Gas-Related Investments. The prices of shares offered by Authorized Participants are expected to fall between UNL’s per share NAV and the trading price of the shares on the NYSE Arca at the time of sale. Shares initially comprising the same basket but offered by Authorized Participants to the public at different times may have different offering prices. An order for one or more baskets may be placed by an Authorized Participant on behalf of multiple clients. Authorized Participants who make deposits with UNL in exchange for baskets receive no fees, commissions or other form of compensation or inducement of any kind from either UNL or USCF, and no such person has any obligation or responsibility to USCF or UNL to effect any sale or resale of shares. Shares trade in the secondary market on the NYSE Arca. Shares may trade in the secondary market at prices that are lower or higher relative to their per share NAV. The amount of the discount or premium in the trading price relative to the per share NAV may be influenced by various factors, including the number of investors who seek to purchase or sell shares in the secondary market and the liquidity of the Futures Contracts market and the market for Other Natural Gas-Related Investments. While the shares trade during the core trading session on the NYSE Arca until 4:00 p.m. New York time, liquidity in the market for Futures Contracts and Other Natural Gas-Related Investments may be reduced after the close of the NYMEX at 2:30 p.m. New York time. As a result, during this time, trading spreads, and the resulting premium or discount, on the shares may widen.

19

Investments

USCF causes UNL to transfer the proceeds from the sale of Creation Baskets to the Custodian or other custodian for trading activities. USCF will invest UNL’s assets in Futures Contracts and Other Natural Gas-Related Investments and investments in Treasuries, cash and/or cash equivalents. When UNL purchases a Futures Contract and certain exchange-traded Other Natural Gas-Related Investments, UNL is required to deposit 5% to 30% with the selling FCM on behalf of the exchange a portion of the value of the contract or other interest as security to ensure payment for the obligation under Natural Gas Interests at maturity. This deposit is known as initial margin. Counterparties in transactions in over-the-counter Natural Gas Interests will generally impose similar collateral requirements on UNL. USCF will invest the assets that remain after margin and collateral are posted in Treasuries, cash and/or cash equivalents subject to these margin and collateral requirements. USCF has sole authority to determine the percentage of assets that are:

• | held on deposit with the FCM or other custodian,
• | used for other investments, and
• | held in bank accounts to pay current obligations and as reserves.

Ongoing margin and collateral payments will generally be required for both exchange-traded and over-the-counter Natural Gas Interests based on changes in the value of the Natural Gas Interests. Furthermore, ongoing collateral requirements with respect to over-the-counter Natural Gas Interests are negotiated by the parties, and may be affected by overall market volatility, volatility of the underlying commodity or index, the ability of the counterparty to hedge its exposure under a Natural Gas Interest and each party’s creditworthiness. In light of the differing requirements for initial payments under exchange-traded and over-the-counter Natural Gas Interests and the fluctuating nature of ongoing margin and collateral payments, it is not possible to estimate what portion of UNL’s assets will be posted as margin or collateral at any given time. The Treasuries, cash and cash equivalents held by UNL will constitute reserves that will be available to meet ongoing margin and collateral requirements. All interest income will be used for UNL’s benefit.

A FCM, counterparty, government agency or commodity exchange could increase margin or collateral requirements applicable to UNL to hold trading positions at any time. Moreover, margin is merely a security deposit and has no bearing on the profit or loss potential for any positions held.

The assets of UNL posted as margin for Futures Contracts are held in segregated accounts pursuant to the CEA and CFTC regulations.

If UNL enters into a swap agreement, UNL must post both collateral and independent amounts to its swap counterparties. The amount of collateral UNL posts changes according to the amounts owed by UNL to its counterparty on a given swap transaction, while independent amounts are fixed amounts posted by UNL at the start of a swap transaction. Collateral and independent amounts posted to swap counterparties will be held by a third party custodian.

The Commodity Interest Markets

General

The CEA governs the regulation of commodity interest transactions, markets and intermediaries. The CEA provides for varying degrees of regulation of commodity interest transactions depending upon: (1) the type of instrument being traded (e.g., contracts for future delivery, options, swaps or spot contracts), (2) the type of commodity underlying the instrument (distinctions are made between instruments based on agricultural commodities, energy and metals commodities and financial commodities), (3) the nature of the parties to the transaction (retail, eligible contract participant, or eligible commercial entity), (4) whether the transaction is entered into on a principal-to-principal or intermediated basis, (5) the type of market on which the transaction occurs, and (6) whether the transaction is subject to clearing through a clearing organization.

The offer and sale of shares of UNL, as well as shares of each Related Public Fund, is registered under the Securities Act. UNL and the Related Public Funds are subject to the requirements of the Securities Act, the Exchange Act and the rules and regulations adopted thereunder as administered by the SEC. Firms’ participation in the distribution of shares is regulated as described above, as well as by the self-regulatory association, FINRA.

20

Futures Contracts

A futures contract is a standardized contract traded on, or subject to the rules of, an exchange that calls for the future delivery of a specified quantity and type of a commodity at a specified time and place. Futures contracts are traded on a wide variety of commodities, including agricultural products, bonds, stock indices, interest rates, currencies, energy and metals. The size and terms of futures contracts on a particular commodity are identical and are not subject to any negotiation, other than with respect to price and the number of contracts traded between the buyer and seller.

The contractual obligations of a buyer or seller may generally be satisfied by taking or making physical delivery of the underlying commodity or by making an offsetting sale or purchase of an identical futures contract on the same or linked exchange before the designated date of delivery. The difference between the price at which the futures contract is purchased or sold and the price paid for the offsetting sale or purchase, after allowance for brokerage commissions, constitutes the profit or loss to the trader. Some futures contracts, such as stock index contracts, settle in cash (reflecting the difference between the contract purchase/sale price and the contract settlement price) rather than by delivery of the underlying commodity.

In market terminology, a trader who purchases a futures contract is long in the market and a trader who sells a futures contract is short in the market. Before a trader closes out his long or short position by an offsetting sale or purchase, his outstanding contracts are known as open trades or open positions. The aggregate amount of open positions held by traders in a particular contract is referred to as the open interest in such contract.

Forward Contracts

A forward contract is a contractual obligation to purchase or sell a specified quantity of a commodity at or before a specified date in the future at a specified price and, therefore, is economically similar to a futures contract. Unlike futures contracts, however, forward contracts are typically traded in the OTC markets and are not standardized contracts. Forward contracts for a given commodity are generally available for various amounts and maturities and are subject to individual negotiation between the parties involved. Moreover, generally there is no direct means of offsetting or closing out a forward contract by taking an offsetting position as one would a futures contract on a U.S. exchange. If a trader desires to close out a forward contract position, he generally will establish an opposite position in the contract but will settle and recognize the profit or loss on both positions simultaneously on the delivery date. Thus, unlike in the futures contract market where a trader who has offset positions will recognize profit or loss immediately, in the forward market a trader with a position that has been offset at a profit will generally not receive such profit until the delivery date, and likewise a trader with a position that has been offset at a loss will generally not have to pay money until the delivery date. In recent years, however, the terms of forward contracts have become more standardized, and in some instances such contracts now provide a right of offset or cash settlement as an alternative to making or taking delivery of the underlying commodity.

In general, the CFTC does not regulate the interbank and forward foreign currency markets with respect to transactions in contracts between certain sophisticated counterparties such as UNL or between certain regulated institutions and retail investors. Although U.S. banks are regulated in various ways by the Federal Reserve Board, the Comptroller of the Currency and other U.S. federal and state banking officials, banking authorities do not regulate the forward markets to the same extent that the swap markets are regulated by the CFTC and SEC. At a minimum, over-the-counter currency forwards, options and swaps will be subject to heightened recordkeeping, reporting and business conduct standards.

Regulation exempts both foreign exchange swaps and foreign exchange forwards from the definition of “swap” and, by extension, additional regulatory requirements (such as clearing and margin). The final determination does not extend to other foreign exchange derivatives, such as foreign exchange options, currency swaps, and non-deliverable forwards.

21

While the U.S. government does not currently impose any restrictions on the movements of currencies, it could choose to do so. The imposition or relaxation of exchange controls in various jurisdictions could significantly affect the market for that and other jurisdictions’ currencies. Trading in the interbank market also exposes UNL to a risk of default since the failure of a bank with which UNL had entered into a forward contract would likely result in a default and thus possibly substantial losses to UNL.

Options on Futures Contracts

Options on futures contracts are standardized contracts traded on an exchange. An option on a futures contract gives the buyer of the option the right, but not the obligation, to take a position at a specified price (the striking, strike, or exercise price) in the underlying futures contract or underlying interest. The buyer of a call option acquires the right, but not the obligation, to purchase or take a long position in the underlying interest, and the buyer of a put option acquires the right, but not the obligation, to sell or take a short position in the underlying interest.

The seller, or writer, of an option is obligated to take a position in the underlying interest at a specified price opposite to the option buyer if the option is exercised. The seller of a call option must stand ready to take a short position in the underlying interest at the strike price if the buyer should exercise the option. The seller of a put option, on the other hand, must stand ready to take a long position in the underlying interest at the strike price.

A call option is said to be in-the-money if the strike price is below current market levels and out-of-the-money if the strike price is above current market levels. Conversely, a put option is said to be in-the-money if the strike price is above the current market levels and out-of-the-money if the strike price is below current market levels.

Options have limited life spans, usually tied to the delivery or settlement date of the underlying interest. Some options, however, expire significantly in advance of such date. The purchase price of an option is referred to as its premium, which consists of its intrinsic value (which is related to the underlying market value) plus its time value. As an option nears its expiration date, the time value shrinks and the market and intrinsic values move into parity. An option that is out-of-the-money and not offset by the time it expires becomes worthless. On certain exchanges, in-the-money options are automatically exercised on their expiration date, but on others unexercised options simply become worthless after their expiration date.

Regardless of how much the market swings, the most an option buyer can lose is the option premium. The option buyer deposits his premium with his broker, and the money goes to the option seller. Option sellers, on the other hand, face risks similar to participants in the futures markets. For example, since the seller of a call option is assigned a short futures position if the option is exercised, his risk is the same as someone who initially sold a futures contract. Because no one can predict exactly how the market will move, the option seller posts margin to demonstrate his ability to meet any potential contractual obligations.

Options on Forward Contracts or Commodities

Options on forward contracts or commodities operate in a manner similar to options on futures contracts. An option on a forward contract or commodity gives the buyer of the option the right, but not the obligation, to take a position at a specified price in the underlying forward contract or commodity. However, unlike options on futures contracts, options on forward contracts or on commodities are individually negotiated contracts between counterparties and are typically traded in the OTC market. Therefore, options on forward contracts and physical commodities possess many of the same characteristics of forward contracts with respect to offsetting positions and credit risk that are described above.

Swap Contracts

Swap transactions generally involve contracts between two parties to exchange a stream of payments computed by reference to a notional amount and the price of the asset that is the subject of the swap. Swap contracts are principally traded off-exchange, although certain swap contracts are also being traded in electronic trading facilities and cleared through clearing organizations.

22

Swaps are usually entered into on a net basis, that is, the two payment streams are netted out in a cash settlement on the payment date or dates specified in the agreement, with the parties receiving or paying, as the case may be, only the net amount of the two payments. Swaps do not generally involve the delivery of underlying assets or principal. Accordingly, the risk of loss with respect to swaps is generally limited to the net amount of payments that the party is contractually obligated to make. In some swap transactions one or both parties may require collateral deposits from the counterparty to support that counterparty’s obligation under the swap agreement. If the counterparty to such a swap defaults, the risk of loss consists of the net amount of payments that the party is contractually entitled to receive less any collateral deposits it is holding.

Some swap transactions are cleared through central counterparties. These transactions, known as cleared swaps, involve two counterparties first agreeing to the terms of a swap transaction, and then submitting the transaction to a clearing house that acts as the central counterparty. Once accepted by the clearing house, the original swap transaction is novated and the central counterparty becomes the counterparty to a trade with each of the original parties based upon the trade terms determined in the original transaction. In this manner each individual swap counterparty reduces its risk of loss due to counterparty nonperformance because the clearing house acts as the counterparty to each transaction.

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 over-the-counter instruments presently entered into and settled on a bi-lateral basis. If a swap is required to be cleared, the initial margin will be set by the clearing 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.”

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

Regulation 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.

Regulation

Futures exchanges in the United States are subject to varying degrees of regulation under the CEA depending on whether such exchange is a designated contract market, exempt board of trade or electronic trading facility. Clearing organizations are also subject to the CEA and the rules and regulations adopted thereunder and administered by the CFTC. The CFTC is the governmental agency charged with responsibility for regulation of futures exchanges and commodity interest trading conducted on those exchanges. The CFTC’s function is to implement the CEA’s objectives of preventing price manipulation and excessive speculation and promoting orderly and efficient commodity interest markets. In addition, the various exchanges and clearing organizations themselves exercise regulatory and supervisory authority over their member firms.

23

The CFTC also regulates the activities of “commodity trading advisors” and “commodity pool operators” and the CFTC has adopted regulations with respect to certain of such persons’ activities. Pursuant to its authority, the CFTC requires a CPO, such as USCF, to keep accurate, current and orderly records with respect to each pool it operates. The CFTC may suspend, modify or terminate the registration of any registrant for failure to comply with CFTC rules or regulations. Suspension, restriction or termination of USCF’s registration as a CPO would prevent it, until such time (if any) as such registration were to be reinstated, from managing, and might result in the termination of, UNL or the Related Public Funds.

The CEA also gives the states certain powers to enforce its provisions and the regulations of the CFTC.

Under certain circumstances, the CEA grants shareholders the right to institute a reparations proceeding before the CFTC against USCF (as a registered commodity pool operator), as well as those of their respective employees who are required to be registered under the CEA. Shareholders may also be able to maintain a private right of action for certain violations of the CEA.

Pursuant to authority in the CEA, the NFA has been formed and registered with the CFTC as a registered futures association. The NFA is the only self-regulatory association for commodities professionals other than the exchanges. As such, the NFA promulgates rules governing the conduct of commodity professionals and disciplines those professionals that do not comply with such standards. The CFTC has delegated to the NFA responsibility for the registration of commodity pool operation. USCF is a member of the NFA. As a member of the NFA, USCF is subject to NFA standards relating to fair trade practices, financial condition and consumer protection. The CFTC is prohibited by statute from regulating trading on foreign commodity exchanges and markets.

The CEA requires all FCMs, such as UNL’s clearing brokers, to meet and maintain specified fitness and financial requirements, to segregate customer funds from proprietary funds and account separately for all customers’ funds and positions, and to maintain specified books and records open to inspection by the staff of the CFTC. The CFTC has similar authority over introducing brokers, or persons who solicit or accept orders for commodity interest trades but who do not accept margin deposits for the execution of trades. The CEA authorizes the CFTC to regulate trading by FCMs and by their officers and directors, permits the CFTC to require action by exchanges in the event of market emergencies, and establishes an administrative procedure under which customers may institute complaints for damages arising from alleged violations of the CEA. The CEA also gives the states powers to enforce its provisions and the regulations of the CFTC.

The regulations of the CFTC and the NFA prohibit any representation by a person registered with the CFTC or by any member of the NFA, that registration with the CFTC, or membership in the NFA, in any respect indicates that the CFTC or the NFA, as the case may be, has approved or endorsed that person or that person’s trading program or objectives. The registrations and memberships of the parties described in this summary must not be considered as constituting any such approval or endorsement. Likewise, no futures exchange has given or will give any similar approval or endorsement.

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.

UNL’s investors are afforded prescribed rights for reparations under the CEA against USCF (as a registered commodity pool operator), as well as its respective employees who are required to be registered under the CEA. Investors may also be able to maintain a private right of action for violations of the CEA. The CFTC has adopted rules implementing the reparation provisions of the CEA, which provide that any person may file a complaint for a reparations award with the CFTC for violation of the CEA against a floor broker or a FCM, introducing broker, commodity trading advisor, CPO, and their respective associated persons.

24

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 CFTC, 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 traded 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 DCMs and 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. Furthermore, 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 over-the-counter 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 ten percent (10%) 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.

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.

Commodity Margin

Original or initial margin is the minimum amount of funds that must be deposited by a commodity interest trader with the trader’s broker to initiate and maintain an open position in futures contracts. Maintenance margin is the amount (generally less than the original margin) to which a trader’s account may decline before he must deliver additional margin. A margin deposit is like a cash performance bond. It helps assure the trader’s performance of the futures contracts that he or she purchases or sells. Futures contracts are customarily bought and sold on initial margin that represents a very small percentage (ranging upward from less than 5%) of the aggregate purchase or sales price of the contract. Because of such low margin requirements, price fluctuations occurring in the futures markets may create profits and losses that, in relation to the amount invested, are greater than are customary in other forms of investment or speculation. As discussed below, adverse price changes in the futures contract may result in margin requirements that greatly exceed the initial margin. In addition, the amount of margin required in connection with a particular futures contract is set from time to time by the exchange on which the contract is traded and may be modified from time to time by the exchange during the term of the contract.

25

Brokerage firms, such as UNL’s clearing brokers, carrying accounts for traders in commodity interest contracts may not accept lower, and generally require higher, amounts of margin as a matter of policy to further protect themselves. The clearing brokers require UNL to make margin deposits equal to exchange minimum levels for all commodity interest contracts. This requirement may be altered from time to time in the clearing brokers’ discretion.

Regulators have not yet finalized the Dodd-Frank Act rules regarding initial margin levels for over-the-counter derivatives. It is possible that such levels may be higher than those for futures contracts. Also initial margin requirements for non-cleared swaps will be subject to higher margin requirements than cleared swaps. And, under pending rule proposals, UNL may be required to post, but not be entitled to receive, initial and variation margin in respect of non-cleared swaps. Until such time as the regulators finalize these margin rules, trading in the OTC markets where no clearing facility is provided generally will not require margin per se. Rather, it will involve the extension of credit between counterparties that is secured by transfers of credit support and/or independent amounts. Credit support is transferred between counterparties in respect of the open over-the-counter derivatives entered into between them, while independent amounts are fixed amounts posted by one or both counterparties at the execution of a particular over-the-counter transaction.

When a trader purchases an option, there is no margin requirement; however, the option premium must be paid in full. When a trader sells an option, on the other hand, he or she is required to deposit margin in an amount determined by the margin requirements established for the underlying interest and, in addition, an amount substantially equal to the current premium for the option. The margin requirements imposed on the selling of options, although adjusted to reflect the probability that out-of-the-money options will not be exercised, can in fact be higher than those imposed in dealing in the futures markets directly. Complicated margin requirements apply to spreads and conversions, which are complex trading strategies in which a trader acquires a mixture of options positions and positions in the underlying interest.

Margin requirements are computed each day by a trader’s clearing broker. When the market value of a particular open commodity interest position changes to a point where the margin on deposit does not satisfy maintenance margin requirements, a margin call is made by the broker. If the margin call is not met within a reasonable time, the broker may close out the trader’s position. With respect to UNL’s trading, UNL (and not its investors personally) is subject to margin calls.

Regulations impose 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.

Finally, many major U.S. exchanges have passed certain cross margining arrangements involving procedures pursuant to which the futures and options positions held in an account would, in the case of some accounts, be aggregated and margin requirements would be assessed on a portfolio basis, measuring the total risk of the combined positions.

General Regulation Applicable to UNL

On August 12, 2013, the CFTC issued final rules establishing compliance obligations for commodity pool operators (“CPOs”) of investment companies registered under the 1940 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 1940 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.

26

On July 23, 2014, the SEC adopted final rules governing the structure and operation of money market funds, in a release adopting amendments to Rule 2a-7 under the 1940 Act. The new rules will require institutional prime money market funds to price their shares using market-based values instead of the amortized cost method (i.e., to use a “floating NAV”). In addition, all money market funds will be able, and in certain cases will be required, to impose liquidity fees and temporarily suspend redemptions during periods of market stress, subject to certain board findings. Finally, the SEC also revised certain diversification provisions of Rule 2a-7, as well as provisions relating to stress testing. 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 Futures Contracts. It is unclear at this time what impact of money market reform would have on UNL’s ability to hedge risk, however, the imposition of a floating NAV could cause UNL to limit remaining assets solely in Treasuries and cash.

With regard to any other rules that the CFTC or SEC may adopt in the future, the effect of any such regulatory changes on UNL is impossible to predict, but it could be substantial and adverse.

| Item 1A. | Risk Factors.

The following risk factors should be read in connection with the other information included in this annual report on Form 10-K, including Management’s Discussion and Analysis of Financial Condition and Results of Operations and UNL’s financial statements and the related notes.

UNL’s investment objective is for the daily changes in percentage terms of its shares’ per share net asset value (“NAV”) to reflect the daily changes in percentage terms of the spot price of natural gas delivered at the Henry Hub, Louisiana, as measured by the daily changes in the average of the prices of the Benchmark Futures Contracts, less UNL’s expenses. UNL seeks to achieve its investment objective by investing in a combination of Futures Contracts and Other Natural Gas-Related Investments such that the daily changes in its NAV, measured in percentage terms, will closely track the changes in the average in the prices of the Benchmark Futures Contracts, also measured in percentage terms. UNL’s investment strategy is designed to provide investors with a cost-effective way to invest indirectly in natural gas and to hedge against movements in the spot price of natural gas. An investment in UNL involves investment risk similar to a direct investment in Futures Contracts and Other Natural Gas-Related Investments, and correlation risk, or the risk that investors purchasing shares to hedge against movements in the price of natural gas will have an efficient hedge only if the price they pay for their shares closely correlates with the price of natural gas. In addition to investment risk and correlation risk, an investment UNL involves tax risks, over-the-counter risks and other risks.

Investment Risk

The daily changes in percentage terms of UNL’s shares per share net asset value relates directly to daily changes in the average of the prices of the Benchmark Futures Contracts and other assets held by UNL and fluctuations in the prices of these assets could materially adversely affect an investment in UNL’s shares.

The net assets of UNL consist primarily of investments in Futures Contracts and, to a lesser extent, in Other Natural Gas-Related Investments. The NAV of UNL’s shares relates directly to the value of these assets (less liabilities, including accrued but unpaid expenses), which in turn relates to the price of natural gas in the marketplace. Natural gas prices depend on local, regional and global events or conditions that affect supply and demand for natural gas.

Economic conditions. The demand for natural gas correlates closely with general economic growth rates. The occurrence of recessions or other periods of low or negative economic growth will typically have a direct adverse impact on natural gas demand and therefore may have an adverse impact on natural gas prices.

Other demand-related factors. Other factors that may affect the demand for natural gas and therefore its price, include technological improvements in energy efficiency; seasonal weather patterns, which affect the demand for natural gas associated with heating; increased competitiveness of alternative energy sources that have so far generally not been competitive with natural gas without the benefit of government subsidies or mandates; and changes in technology or consumer preferences that alter fuel choices, such as toward alternative fueled vehicles.

Other supply-related factors. Natural gas prices also vary depending on a number of factors affecting supply. For example, increased supply from the development of new natural gas sources and technologies to enhance recovery from existing sources tends to reduce natural gas prices to the extent such supply increases are not offset by commensurate growth in demand. Similarly, increases in industry refining or manufacturing capacity may impact the supply of natural gas. Natural gas supply levels can also be affected by factors that reduce available supplies, such natural disasters, disruptions in competitors’ operations, or unexpected unavailability of distribution channels that may disrupt supplies. Technological change can also alter the relative costs for companies in the natural gas industry to find, produce, and transport natural gas, which in turn, may affect the supply of and demand for natural gas.

28

Other market factors. The supply of and demand for natural gas may also be impacted by changes in interest rates, inflation, and other local or regional market conditions.

Correlation Risk

Investors purchasing shares to hedge against movements in the price of natural gas will have an efficient hedge only if the price they pay for their shares closely correlates with the price of natural gas. Investing in UNL’s shares for hedging purposes involves the following risks:

| · | The market price at which the investor buys or sells shares may be significantly less or more than NAV.

| · | Daily percentage changes in NAV may not closely correlate with daily percentage changes in the average of the prices of the Benchmark Futures Contracts.

| · | Daily percentage changes in the average of the prices of the Benchmark Futures Contracts may not closely correlate with daily percentage changes in the price of natural gas.

The market price at which investors buy or sell shares may be significantly less or more than net asset value.

UNL’s NAV per share will change throughout the day as fluctuations occur in the market value of UNL’s portfolio investments. The public trading price at which an investor buys or sells shares during the day from their broker may be different from the NAV of the shares. Price differences may relate primarily to supply and demand forces at work in the secondary trading market for shares that are closely related to, but not identical to, the same forces influencing the prices of the natural gas and the Benchmark Futures Contracts at any point in time. USCF expects that exploitation of certain arbitrage opportunities by Authorized Participants and their clients and customers will tend to cause the public trading price to track NAV per share closely over time, but there can be no assurance of that.

The NAV of UNL’s shares may also be influenced by non-concurrent trading hours between the NYSE Arca and the various futures exchanges on which natural gas is traded. While the shares trade on the NYSE Arca from 9:30 a.m. to 4:00 p.m. Eastern Time, the trading hours for the futures exchanges on which natural gas trades may not necessarily coincide during all of this time. For example, while the shares trade on the NYSE Arca until 4:00 p.m. Eastern Time, liquidity in the natural gas market will be reduced after the close of the NYMEX at 2:30 p.m. Eastern Time. As a result, during periods when the NYSE Arca is open and the futures exchanges on which natural gas is traded are closed, trading spreads and the resulting premium or discount on the shares may widen and, therefore, increase the difference between the price of the shares and the NAV of the shares.

Daily percentage changes in UNL’s net asset value may not correlate with daily percentage changes in the average of the prices of the Benchmark Futures Contracts.

It is possible that the daily percentage changes in UNL’s NAV per share may not closely correlate to daily percentage changes in the average of the prices of the Benchmark Futures Contracts. Non-correlation may be attributable to disruptions in the market for natural gas, the imposition of position or accountability limits by regulators or exchanges, or other extraordinary circumstances. As UNL approaches or reaches position limits with respect to the Benchmark Futures Contracts and other Futures Contracts or in view of market conditions, UNL may begin investing in Other Natural Gas-Related Investments. In addition, UNL is not able to replicate exactly the changes in the price of the Benchmark Futures Contract because the total return generated by UNL is reduced by expenses and transaction costs, including those incurred in connection with UNL’s trading activities, and increased by interest income from UNL’s holdings of Treasury securities. Tracking the Benchmark Futures Contracts requires trading of UNL’s portfolio with a view to tracking the Benchmark Futures Contracts over time and is dependent upon the skills of USCF and its trading principals, among other factors.

29

Daily percentage changes in the price of the Benchmark Futures Contracts may not correlate with daily percentage changes in the spot price of natural gas.

The correlation between changes in prices of the Benchmark Futures Contracts and the spot price of natural gas may at times be only approximate. The degree of imperfection of correlation depends upon circumstances such as variations in the speculative natural gas market, supply of and demand for Futures Contracts (including the Benchmark Futures Contracts) and Other Natural Gas-Related Investments, and technical influences in natural gas futures trading.

Natural forces in the natural gas futures market known as “backwardation” and “contango” may increase UNL’s tracking error and/or negatively impact total return.

The design of UNL’s Benchmark Futures Contracts is such that every month it begins by using the near month contract to expire and the contracts for the following 11 months until the near month contract is within two weeks of expiration, when, over a one day period, it transitions to the next month contract to expire and the contracts for the following 11 months as its benchmark contracts and keeps those contracts as its benchmark until it becomes the near month contract and close to expiration. In the event of a natural gas futures market where near month contracts trade at a higher price than next month to expire contracts, a situation described as “backwardation” in the futures market, then absent the impact of the overall movement in natural gas prices the value of the benchmark contract would tend to rise as it approaches expiration. Conversely, in the event of a natural gas futures market where near month contracts trade at a lower price than next month contracts, a situation described as “contango” in the futures market, then absent the impact of the overall movement in natural gas prices the value of the Benchmark Futures Contracts would tend to decline as it approaches expiration. When compared to total return of other price indices, such as the spot price of natural gas, the impact of backwardation and contango may cause the total return of UNL’s per share NAV to vary significantly. Moreover, absent the impact of rising or falling natural gas prices, a prolonged period of contango could have a significant negative impact on UNL’s per share NAV and total return and investors could lose part or all of their investment. See “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” in this annual report on Form 10-K for a discussion of the potential effects of contango and backwardation.

Accountability levels, position limits, and daily price fluctuation limits set by the exchanges have the potential to cause tracking error, which could cause the price of shares to substantially vary from the average of the prices of the Benchmark Futures Contracts.

Designated contract markets, such as the NYMEX, 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. In addition to accountability levels and position limits, the NYMEX also set daily price fluctuation limits on futures contracts. The daily price fluctuation limit establishes the maximum amount that the price of a futures contract may vary either up or down from the previous day’s settlement price. Once the daily price fluctuation limit has been reached in a particular futures contract, no trades may be made at a price beyond that limit.

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 DCMs and 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 trading platforms.

30

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 Futures Contracts and Other Natural Gas-Related Investment 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 over-the-counter 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.

All of these limits may potentially cause a tracking error between the price of UNL’s shares and the average of the prices of the Benchmark Futures Contracts. This may in turn prevent investors from being able to effectively use UNL as a way to hedge against natural gas-related losses or as a way to indirectly invest in natural gas.

UNL has not limited the size of its offering and is committed to utilizing substantially all of its proceeds to purchase Futures Contracts and Other Natural Gas-Related Investments. If UNL encounters accountability levels, position limits, or price fluctuation limits for Futures Contracts on the NYMEX, it may then, if permitted under applicable regulatory requirements, purchase Futures Contracts on other exchanges that trade listed natural gas futures. In addition, if UNL exceeds accountability levels on either the NYMEX and is required by such exchanges to reduce its holdings, such reduction could potentially cause a tracking error between the price of UNL’s shares and the average of the prices of the Benchmark Futures Contracts.

Tax Risk

An investor’s tax liability may exceed the amount of distributions, if any, on its shares.

Cash or property will be distributed at the sole discretion of USCF. USCF has not and does not currently intend to make cash or other distributions with respect to shares. Investors will be required to pay U.S. federal income tax and, in some cases, state, local, or foreign income tax, on their allocable share of UNL’s taxable income, without regard to whether they receive distributions or the amount of any distributions. Therefore, the tax liability of an investor with respect to its shares may exceed the amount of cash or value of property (if any) distributed.

An investor’s allocable share of taxable income or loss may differ from its economic income or loss on its shares.

Due to the application of the assumptions and conventions applied by UNL in making allocations for tax purposes and other factors, an investor’s allocable share of UNL’s income, gain, deduction or loss may be different than its economic profit or loss from its shares for a taxable year. This difference could be temporary or permanent and, if permanent, could result in it being taxed on amounts in excess of its economic income.

Items of income, gain, deduction, loss and credit with respect to shares could be reallocated if the U.S. Internal Revenue Service (“IRS”) does not accept the assumptions and conventions applied by UNL in allocating those items, with potential adverse consequences for an investor.

The U.S. tax rules pertaining to partnerships are complex and their application to large, publicly traded partnerships such as UNL is in many respects uncertain. UNL applies certain assumptions and conventions in an attempt to comply with the intent of the applicable rules and to report taxable income, gains, deductions, losses and credits in a manner that properly reflects shareholders’ economic gains and losses. These assumptions and conventions may not fully comply with all aspects of the Internal Revenue Code (the “Code”) and applicable Treasury Regulations, however, and it is possible that the IRS will successfully challenge UNL’s allocation methods and require UNL to reallocate items of income, gain, deduction, loss or credit in a manner that adversely affects investors. If this occurs, investors may be required to file an amended tax return and to pay additional taxes plus deficiency interest.

31

UNL could be treated as a corporation for federal income tax purposes, which may substantially reduce the value of the shares.

UNL has received an opinion of counsel that, under current U.S. federal income tax laws, UNL will be treated as a partnership that is not taxable as a corporation for U.S. federal income tax purposes, provided that (i) at least 90 percent of UNL’s annual gross income consists of “qualifying income” as defined in the Code, (ii) UNL is organized and operated in accordance with its governing agreements and applicable law and (iii) UNL does not elect to be taxed as a corporation for federal income tax purposes. Although USCF anticipates that UNL has satisfied and will continue to satisfy the “qualifying income” requirement for all of its taxable years, that result cannot be assured. UNL has not requested and will not request any ruling from the IRS with respect to its classification as a partnership not taxable as a corporation for federal income tax purposes. If the IRS were to successfully assert that UNL is taxable as a corporation for federal income tax purposes in any taxable year, rather than passing through its income, gains, losses and deductions proportionately to shareholders, UNL would be subject to tax on its net income for the year at corporate tax rates. In addition, although USCF does not currently intend to make distributions with respect to shares, any distributions would be taxable to shareholders as dividend income. Taxation of UNL as a corporation could materially reduce the after-tax return on an investment in shares and could substantially reduce the value of the shares.

UNL is organized and operated as a limited partnership in accordance with the provisions of the LP Agreement and applicable state law, and therefore, UNL has a more complex tax treatment than traditional mutual funds.

UNL is organized and operated as a limited partnership in accordance with the provisions of the LP Agreement and applicable state law. No U.S. federal income tax is paid by UNL on its income. Instead, UNL will furnish shareholders each year with tax information on IRS Schedule K-1 (Form 1065) and each U.S. shareholder is required to report on its U.S. federal income tax return its allocable share of the income, gain, loss and deduction of UNL.

This must be reported without regard to the amount (if any) of cash or property the shareholder receives as a distribution from UNL during the taxable year. A shareholder, therefore, may be allocated income or gain by UNL but receive no cash distribution with which to pay the tax liability resulting from the allocation, or may receive a distribution that is insufficient to pay such liability.

In addition to federal income taxes, shareholders may be subject to other taxes, such as state and local income taxes, unincorporated business taxes, business franchise taxes and estate, inheritance or intangible taxes that may be imposed by the various jurisdictions in which UNL does business or owns property or where the shareholders reside. Although an analysis of those various taxes is not presented here, each prospective shareholder should consider their potential impact on its investment in UNL. It is each shareholder’s responsibility to file the appropriate U.S. federal, state, local and foreign tax returns.

Over-the-Counter Contract Risk

Currently, over-the-counter transactions are subject to changing regulation.

A portion of UNL’s assets may be used to trade over-the-counter contracts, such as forward contracts or swap or spot contracts. Over-the-counter contracts are typically contracts traded on a principal-to-principal, non-cleared basis through dealer markets that are dominated by major money center and investment banks and other institutions. The markets for over-the-counter contracts rely upon the integrity of market participants in lieu of the additional regulation imposed by the CFTC on participants in the futures markets. While certain regulations adopted over the past two years are intended to provide additional protections to participants in the OTC market, the current regulation of the over-the-counter contracts could expose UNL in certain circumstances to significant losses in the event of trading abuses or financial failure by participants. As a result of such regulations, if UNL enters 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 over-the-counter instruments presently entered into and settled on a bi-lateral basis. See “Item 1. Business – Regulation” for a discussion of how the OTC market will be subject to much more extensive regulatory oversight.

32

UNL will be subject to credit risk with respect to counterparties to over-the-counter contracts entered into by UNL or held by special purpose or structured vehicles.

UNL faces the risk of non-performance by the counterparties to the over-the-counter contracts. Unlike in futures contracts, the counterparty to these contracts is generally a single bank or other financial institution, rather than a clearing organization backed by a group of financial institutions. As a result, there will be greater counterparty credit risk in these transactions. A counterparty may not be able to meet its obligations to UNL, in which case UNL could suffer significant losses on these contracts.

If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, UNL may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. UNL may obtain only limited recovery or may obtain no recovery in such circumstances.

Valuing over-the-counter derivatives may be less certain that actively traded financial instruments.

In general, valuing over-the-counter 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 over-the-counter 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 over-the-counter 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 over-the-counter derivatives transaction.

Other Risks

Certain of UNL’s investments could be illiquid, which could cause large losses to investors at any time or from time to time.

Futures positions cannot always be liquidated at the desired price. It is difficult to execute a trade at a specific price when there is a relatively small volume of buy and sell orders in a market. A market disruption, such as a foreign government taking political actions that disrupt the market for its currency, its natural gas production or exports, or another major export, can also make it difficult to liquidate a position. Because both Futures Contracts and Other Natural Gas-Related Investments may be illiquid, UNL's Natural Gas Interests may be more difficult to liquidate at favorable prices in periods of illiquid markets and losses may be incurred during the period in which positions are being liquidated. The large size of the positions that UNL may acquire increases the risk of illiquidity both by making its positions more difficult to liquidate and by potentially increasing losses while trying to do so.

Over-the-counter contracts that are not subject to clearing may be even less marketable that futures contracts because they are not traded on an exchange, do not have uniform terms and conditions, and are entered into based upon the creditworthiness of the parties and the availability of credit support, such as collateral, and in general, they are not transferable without the consent of the counterparty. These conditions make such contracts less liquid than standardized futures contracts traded on a commodities exchange and could adversely impact UNL’s ability to realize the full value of such contracts. In addition, even if collateral is used to reduce counterparty credit risk, sudden changes in the value of over-the-counter 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.

UNL is not actively managed and tracks the Benchmark Futures Contracts during periods in which the price of the Benchmark Futures Contracts is flat or declining as well as when the price is rising.

UNL is not actively managed by conventional methods. Accordingly, if UNL’s investments in Natural Gas Interests are declining in value, UNL will not close out such positions except in connection with paying the proceeds to an Authorized Participant upon the redemption of a basket or closing out futures positions in connection with the monthly change in the Benchmark Futures Contracts. USCF will seek to cause the NAV of UNL’s shares to track the Benchmark Futures Contracts during periods in which its price is flat or declining as well as when the price is rising.

33

The NYSE Arca may halt trading in UNL’s shares, which would adversely impact an investor’s ability to sell shares.

UNL’s shares are listed for trading on the NYSE Arca under the market symbol “UNL.” Trading in shares may be halted due to market conditions or, in light of NYSE Arca rules and procedures, for reasons that, in the view of the NYSE Arca, make trading in shares inadvisable. In addition, trading is subject to trading halts caused by extraordinary market volatility pursuant to “circuit breaker” rules that require trading to be halted for a specified period based on a specified market decline. Additionally, there can be no assurance that the requirements necessary to maintain the listing of UNL’s shares will continue to be met or will remain unchanged.

The lack of an active trading market for UNL’s shares may result in losses on an investor’s investment in UNL at the time the investor sells the shares.

Although UNL’s shares are listed and traded on the NYSE Arca, there can be no guarantee that an active trading market for the shares will be maintained. If an investor needs to sell shares at a time when no active trading market for them exists, the price the investor receives upon sale of the shares, assuming they were able to be sold, likely would be lower than if an active market existed.

USCF is leanly staffed and relies heavily on key personnel to manage UNL and other funds.

USCF was formed to be the sponsor and manager of investment vehicles such as UNL and has been managing such investment vehicles since April 2006. Since April 2006, the Chief Investment Officer and Chief Financial Officer have been managing and directing the day-to-day activities and affairs of UNL. Since January 2015, Mr. Gerber has assumed a more active role in the day-to-day activities of USCF, UNL and the Related Public Funds. The Chief Investment Officer has resigned effective May 1, 2015. Mr. Gerber has stated that it is his intent to not replace the Chief Investment Officer’s position, but to utilize current and future staff to fill any material gaps that may ensue from the Chief Investment Officer’s departure. There is a risk that not replacing the Chief Investment Officer may have a material adverse effect on the management and/or financial results of UNL.

The Fifth Amended and Restated Limited Liability Company Agreement of USCF (the “LLC Agreement”) provides limited authority to the Non-Management Directors, and any Director of USCF may be removed by USCF’s parent company, which is a closely-held private company where the majority of shares has historically been voted by one person.

USCF’s Board of Directors currently consists of three Management Directors, each of whom are shareholders of USCF’s parent, Wainwright Holdings, Inc. (“Wainwright”), and three Non-Management Directors, each of whom are considered independent for purposes of applicable NYSE Arca and SEC rules. Under USCF’s LLC Agreement, the Non-Management Directors have only such authority as the Management Directors expressly confer upon them, which means that the Non-Management Directors may have less authority to control the actions of the Management Directors than is typically the case with the independent members of a company’s Board of Directors. In addition, any Director may be removed by written consent of Wainwright, which is the sole member of USCF. Wainwright is a privately held company in which the majority of shares are held by or on behalf of Nicholas D. Gerber and his immediate family members (the “Gerber Family”). Historically, shares of Wainwright have been voted by, and on behalf of, the Gerber Family by Nicholas D. Gerber, and it is anticipated that such trend will continue in the future. Accordingly, although USCF is governed by the USCF Board of Directors, which consists of both Management Directors and Non-Management Directors, pursuant to the LLC Agreement, it is possible for Mr. Gerber to exercise his control of Wainwright to effect the removal of any Director (including the Non-Management Directors which comprise the Audit Committee) and to replace that Director with another Director. Having control in one person could have a negative impact on USCF and UNL, including their regulatory obligations.

34

There is a risk that UNL will not earn trading gains sufficient to compensate for the fees and expenses that it must pay and as such UNL may not earn any profit.

UNL pays brokerage charges of approximately 0.04% of average total net assets based on brokerage fees of $3.50 per buy or sell, management fees of 0.75% of NAV on its average net assets and over-the-counter spreads and extraordinary expenses (e.g., subsequent offering expenses, other expenses not in the ordinary course of business, including the indemnification of any person against liabilities and obligations to the extent permitted by law and required under the LP Agreement and under agreements entered into by USCF on UNL’s behalf and the bringing and defending of actions at law or in equity and otherwise engaging in the conduct of litigation and the incurring of legal expenses and the settlement of claims and litigation) that cannot be quantified.

These fees and expenses must be paid in all cases regardless of whether UNL’s activities are profitable. Accordingly, UNL must earn trading gains sufficient to compensate for these fees and expenses before it can earn any profit.

Regulation of the commodity interests and energy markets is extensive and constantly changing; future regulatory developments are impossible to predict but may significantly and adversely affect UNL.

The futures markets are subject to comprehensive statutes, regulations, and margin requirements. In addition, the CFTC and futures exchanges are authorized to take extraordinary actions in the event of a market emergency, including, for example, the retroactive implementation of speculative position limits or higher margin requirements, the establishment of daily price limits and the suspension of trading. Regulation of commodity interest transactions in the United States is a rapidly changing area of law and is subject to ongoing modification by governmental and judicial action. Considerable regulatory attention has been focused on non-traditional investment pools that are publicly distributed in the United States. In addition, various national governments outside of the United States have expressed concern regarding the disruptive effects of speculative trading in the energy markets and the need to regulate the derivatives markets in general. The effect of any future regulatory change on UNL is impossible to predict, but it could be substantial and adverse. For a more detailed discussion of the regulations to be imposed by the CFTC and the SEC and the potential impacts thereof on UNL, please see “Item 1. Business – Regulation” in this annual report on Form 10-K.

An investment in UNL may provide little or no diversification benefits. Thus, in a declining market, UNL may have no gains to offset losses from other investments, and an investor may suffer losses on an investment in UNL while incurring losses with respect to other asset classes.

Historically, Futures Contracts and Other Natural Gas-Related Investments have generally been non-correlated to the performance of other asset classes such as stocks and bonds. Non-correlation means that there is a low statistically valid relationship between the performance of futures and other commodity interest transactions, on the one hand, and stocks or bonds, on the other hand.

However, there can be no assurance that such non-correlation will continue during future periods. If, contrary to historic patterns, UNL’s performance were to move in the same general direction as the financial markets, investors will obtain little or no diversification benefits from an investment in UNL’s shares. In such a case, UNL may have no gains to offset losses from other investments, and investors may suffer losses on their investment in UNL at the same time they incur losses with respect to other investments.

35

Variables such as drought, floods, weather, embargoes, tariffs and other political events may have a larger impact on natural gas prices and natural gas-linked instruments, including Futures Contracts and Other Natural Gas-Related Investments, than on traditional securities. These additional variables may create additional investment risks that subject UNL’s investments to greater volatility than investments in traditional securities.

Non-correlation should not be confused with negative correlation, where the performance of two asset classes would be opposite of each other. There is no historical evidence that the spot price of natural gas and prices of other financial assets, such as stocks and bonds, are negatively correlated. In the absence of negative correlation, UNL cannot be expected to be automatically profitable during unfavorable periods for the stock market, or vice versa.

UNL is not a registered investment company so shareholders do not have the protections of the Investment Company Act of 1940, as amended (the “ 1940 Act”).

UNL is not an investment company subject to the 1940 Act. Accordingly, investors do not have the protections afforded by that statute which, for example, requires investment companies to have a majority of disinterested directors and regulates the relationship between the investment company and its investment manager.

Trading in international markets could expose UNL to credit and regulatory risk.

UNL invests primarily in Futures Contracts, a significant portion of which are traded on United States exchanges, including the NYMEX. However, a portion of UNL’s trades may take place on markets and exchanges outside the United States. Some non-U.S. markets present risks because they are not subject to the same degree of regulation as their U.S. counterparts. Trading in non-U.S. markets also leaves UNL susceptible to swings in the value of the local currency against the U.S. dollar. Additionally, trading on non-U.S. exchanges is subject to the risks presented by exchange controls, expropriation, increased tax burdens and exposure to local economic declines and political instability. An adverse development with respect to any of these variables could reduce the profit or increase the loss earned on trades in the affected international markets.

UNL and USCF may have conflicts of interest, which may permit them to favor their own interests to the detriment of shareholders.

UNL is subject to actual and potential inherent conflicts involving USCF, various commodity futures brokers and Authorized Participants. USCF’s officers, directors and employees do not devote their time exclusively to UNL. These persons are directors, officers or employees of other entities that may compete with UNL for their services. They could have a conflict between their responsibilities to UNL and to those other entities. As a result of these and other relationships, parties involved with UNL have a financial incentive to act in a manner other than in the best interests of UNL and the shareholders. USCF has not established any formal procedure to resolve conflicts of interest. Consequently, investors are dependent on the good faith of the respective parties subject to such conflicts of interest to resolve them equitably. Although USCF attempts to monitor these conflicts, it is extremely difficult, if not impossible, for USCF to ensure that these conflicts do not, in fact, result in adverse consequences to the shareholders.

UNL may also be subject to certain conflicts with respect to the FCM, including, but not limited to, conflicts that result from receiving greater amounts of compensation from other clients, or purchasing opposite or competing positions on behalf of third party accounts traded through the FCM. In addition, USCF’s principals, officers, directors or employees may trade futures and related contracts for their own account. A conflict of interest may exist if their trades are in the same markets and at the same time as UNL trades using the clearing broker to be used by UNL. A potential conflict also may occur if USCF’s principals, officers, directors or employees trade their accounts more aggressively or take positions in their accounts which are opposite, or ahead of, the positions taken by UNL.

36

UNL could terminate at any time and cause the liquidation and potential loss of an investor’s investment and could upset the overall maturity and timing of an investor’s investment portfolio.

UNL may terminate at any time, regardless of whether UNL has incurred losses, subject to the terms of the LP Agreement. In particular, unforeseen circumstances, including the death, adjudication of incompetence, bankruptcy, dissolution, or removal of USCF as the general partner of UNL could cause UNL to terminate unless a majority interest of the limited partners within 90 days of the event elects to continue the partnership and appoints a successor general partner, or the affirmative vote of a majority in interest of the limited partners subject to certain conditions. However, no level of losses will require USCF to terminate UNL. UNL’s termination would cause the liquidation and potential loss of an investor’s investment. Termination could also negatively affect the overall maturity and timing of an investor’s investment portfolio.

UNL does not expect to make cash distributions.

UNL has not previously made any cash distributions and intends to reinvest any realized gains in additional Natural Gas Interests rather than distributing cash to limited partners. Therefore, unlike mutual funds, commodity pools or other investment pools that actively manage their investments in an attempt to realize income and gains from their investing activities and distribute such income and gains to their investors, UNL generally does not expect to distribute cash to limited partners. An investor should not invest in UNL if the investor will need cash distributions from UNL to pay taxes on its share of income and gains of UNL, if any, or for any other reason. Nonetheless, although UNL does not intend to make cash distributions, the income earned from its investments held directly or posted as margin may reach levels that merit distribution, e.g., at levels where such income is not necessary to support its underlying investments in Natural Gas Interests and investors adversely react to being taxed on such income without receiving distributions that could be used to pay such tax. If this income becomes significant then cash distributions may be made.

An unanticipated number of redemption requests during a short period of time could have an adverse effect on UNL’s net asset value.

If a substantial number of requests for redemption of Redemption Baskets are received by UNL during a relatively short period of time, UNL may not be able to satisfy the requests from UNL’s assets not committed to trading. As a consequence, it could be necessary to liquidate positions in UNL’s trading positions before the time that the trading strategies would otherwise dictate liquidation.

Proposed Money Market Reform

On July 23, 2014, the SEC adopted final rules governing the structure and operation of money market funds, in a release adopting amendments to Rule 2a-7 under the 1940 Act. The new rules will require institutional prime money market funds to price their shares using market-based values instead of the amortized cost method (i.e., to use a “floating NAV”). In addition, all money market funds will be able, and in certain cases will be required, to impose liquidity fees and temporarily suspend redemptions during periods of market stress, subject to certain board findings. Finally, the SEC also revised certain diversification provisions of Rule 2a-7, as well as provisions relating to stress testing. 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 Futures Contracts. It is unclear at this time what impact of money market reform would have on UNL’s ability to hedge risk, however, the imposition of a floating NAV could cause UNL to limit remaining assets solely in Treasuries and cash.

The failure or bankruptcy of a clearing broker or UNL’s Custodian could result in a substantial loss of UNL’s assets and could impair UNL in its ability to execute trades.

Under CFTC regulations, a clearing broker maintains customers’ assets in a bulk segregated account. If a clearing broker fails to do so, or even if the customers’ funds are segregated by the clearing broker but the clearing broker is unable to satisfy a substantial deficit in a customer account, the clearing broker’s other customers may be subject to risk of a substantial loss of their funds in the event of that clearing broker’s bankruptcy. In that event, the clearing broker’s customers, such as UNL, are entitled to recover, even in respect of property specifically traceable to them, only a proportional share of all property available for distribution to all of that clearing broker’s customers. The bankruptcy of a clearing broker could result in the complete loss of UNL’s assets posted with the clearing broker although the majority of UNL’s assets are held in Treasuries, cash and/or cash equivalents with the Custodian and would not be impacted by the bankruptcy of a clearing broker. UNL may also be subject to the risk of the failure of, or delay in performance by, any exchanges and markets and their clearing organizations, if any, on which commodity interest contracts are traded.

37

In addition, to the extent UNL’s clearing broker is required to post UNL’s assets as margin to a clearinghouse, the margin will be maintained in an omnibus account containing the margin of all the clearing broker’s customers. If UNL’s clearing broker defaults to a clearinghouse because of a default by one of the clearing broker’s other customers or otherwise, then the clearinghouse can look to all of the margin in the omnibus account, including margin posted by UNL and any other non-defaulting customers of the clearing broker to satisfy the obligations of the clearing broker.

From time to time, clearing brokers may be subject to legal or regulatory proceedings in the ordinary course of their business. A clearing broker’s involvement in costly or time-consuming legal proceedings may divert financial resources or personnel away from the clearing broker’s trading operations, which could impair the clearing broker’s ability to successfully execute and clear UNL’s trades.

In addition, the majority of UNL’s assets are held in Treasuries, cash and/or cash equivalents with the Custodian. The insolvency of the Custodian could result in a complete loss of UNL’s assets held by that Custodian, which, at any given time, would likely comprise a substantial portion of UNL’s total assets.

Third parties may infringe upon or otherwise violate intellectual property rights or assert that USCF has infringed or otherwise violated their intellectual property rights, which may result in significant costs and diverted attention.

It is possible that third parties might utilize UNL’s intellectual property or technology, including the use of its business methods, trademarks and trading program software, without permission. USCF has a patent for UNL’s business method and has registered its trademarks. UNL does not currently have any proprietary software. However, if it obtains proprietary software in the future, any unauthorized use of UNL’s proprietary software and other technology could also adversely affect its competitive advantage. UNL may not have adequate resources to implement procedures for monitoring unauthorized uses of its patents, trademarks, proprietary software and other technology. Also, third parties may independently develop business methods, trademarks or proprietary software and other technology similar to that of USCF or claim that USCF has violated their intellectual property rights, including their copyrights, trademark rights, trade names, trade secrets and patent rights. As a result, USCF may have to litigate in the future to protect its trade secrets, determine the validity and scope of other parties’ proprietary rights, defend itself against claims that it has infringed or otherwise violated other parties’ rights, or defend itself against claims that its rights are invalid. Any litigation of this type, even if USCF is successful and regardless of the merits, may result in significant costs, divert its resources from UNL, or require it to change its proprietary software and other technology or enter into royalty or licensing agreements.

Item 7. | Management’s Discussion and Analysis of Financial Condition and Results of Operations.

The following discussion should be read in conjunction with the financial statements and the notes thereto of UNL included elsewhere in this annual report on Form 10-K.

Forward-Looking Information

This annual report on Form 10-K, 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.

Introduction

UNL, a Delaware limited partnership, is a commodity pool that issues shares that may be purchased and sold on the NYSE Arca. The investment objective of UNL is for the daily changes in percentage terms of its shares’ per share NAV to reflect the daily changes, in percentage terms, of the spot 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 on natural gas traded on 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 contract as measured over a time period greater than one day. USCF believes that it is not practical to manage the portfolio to achieve such an investment goal when investing in Futures Contracts and Other Natural Gas-Related Investments.

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.

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 CFTC, the NFA, the futures exchanges, clearing organizations and other regulatory bodies. Pending final resolution of all applicable regulatory requirements, some examples of how new rules and regulations could impact UNL are discussed in “Item 1. Business” and “Item 1A. Risk Factors” in this annual report on Form 10-K.

Price Movements

Natural gas futures prices were volatile during the year ended December 31, 2014. The average price of the Benchmark Futures Contracts started the year at $4.188. It rose over the course of the year and hit a peak on February 21, 2014 of $4.836. The average low price of the year was on December 31, 2014, when the average price of the Benchmark Futures Contracts was $3.057. The average price of the Benchmark Futures Contracts on December 31, 2014 was $3.057, for a decrease of approximately 27.010% over the year. UNL’s per share NAV began the year at $18.32 and ended the year at $13.69 on December 31, 2014, a decrease of approximately 25.27% over the year. UNL’s per share NAV reached its high for the year on February 21, 2014 at $21.20 and reached its low for the year on December 31, 2014 at $13.69. The average Benchmark Futures Contracts price listed above began with the February 2014 to January 2015 contracts and ended with the February 2015 to January 2016 contracts. The decrease of approximately 27.010% 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 Futures Contracts. An investment in natural gas Futures Contracts would need to be rolled forward during the time period described in order to achieve such a result. Furthermore, the change in the nominal price of these differing natural gas Futures Contracts, measured from the start of the year to the end of the year, 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 year ended December 31, 2014, the natural gas futures market exhibited a period of both contango and backwardation. A backwardated market is one in which the near month natural gas Futures Contract is higher than the price of the next month natural gas Futures Contract, or contracts further away from expiration. A contango market is one in which the price of the near month natural gas Futures Contract is less than the price of the next month natural gas Futures Contract, or contracts further away from expiration. For a discussion of the impact of backwardation and contango on total returns, see “Term Structure of Natural Gas Futures Prices and the Impact on Total Returns” below.

Valuation of 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. The 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, Merrill Lynch Professional Clearing Corp., 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 December 31, 2014, UNL had issued 4,400,000 shares, 1,200,000 of which were outstanding. As of December 31, 2014, there were 25,600,000 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 1940 Act, 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 December 31, 2014, 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.

The decrease in the per share NAV for December 31, 2014, compared to the year ended December 31, 2013; and the year ended December 31, 2013, compared to the year ended December 31, 2012, were primarily due to the decrease in value of the Futures Contracts in which UNL invested.

The decrease in cash assets in overnight deposits and investments in Treasuries and money market funds for December 31, 2014, compared to year ended December 31, 2013; and for the year ended December 31, 2013, compared to the year ended December 31, 2012, were the result of UNL’s smaller size as measured by total net assets.

Average interest income earned on short-term investments held by UNL, including cash, cash equivalents and Treasuries, were similar during the year ended December 31, 2014, compared to the year ended December 31, 2013; and were similar for the year ended December 31, 2013 compared to 2012, as measured on average daily total net assets.

The decrease in total fees and expenses excluding management fees for the year ended December 31, 2014, compared to the year ended December 31, 2013 was due to a decrease in certain of UNL’s expenses; and the increase in total fees and expenses excluding management fees for the year ended December 31, 2013, compared to the year ended December 31, 2012, was due to an increase in certain of UNL’s expenses.

UNL’s total commissions accrued to brokers for the year ended December 31, 2104, compared to the year ended December 31, 2013, was similar; and was similar for the year ended December 31, 2013, compared to the year ended December 31, 2012, as measured as an annualized percentage of average total net assets.

Average interest income earned on short-term investments held by UNL, including cash, cash equivalents and Treasuries, were similar during the three months ended December 31, 2014, compared to the three months ended December 31, 2013; and during the three months ended December 31, 2013, and 2012, as measured on average daily total net assets.

The decrease in total fees and expenses excluding management fees for the three months ended December 31, 2014, compared to the three months ended December 31, 2013 due to a decrease in certain UNL’s expenses. Total fees and expenses excluding management fees for the three months ended December 31, 2013, compared to the year ended December 31, 2012 were similar.

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 average daily changes in the average 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 price 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 0.50% (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 listed natural gas Futures Contracts and Other Natural Gas-Related Investments.

For the 30 valuation days ended December 31, 2014, the simple average daily change in the Benchmark Futures Contracts was (0.861)% while the simple average daily change in the per share NAV of UNL over the same time period was (0.862)%. The average daily difference was (0.0010)% (or (0.10) 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 0.11% 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 first chart below shows the daily movement of UNL’s per share NAV versus the daily movement of the Benchmark Futures Contracts for the 30-valuation day period ended December 31, 2014, the last trading day in December. The second chart below shows the monthly total returns of UNL as compared to the monthly value of the Benchmark Futures Contracts for the three years ended December 31, 2014.

Since the commencement of the offering of UNL shares to the public on November 18, 2009 to December 31, 2014, the simple average daily change in the average price of its Benchmark Futures Contracts was (0.081)%, while the simple average daily change in the per share NAV of UNL over the same time period was (0.085)%. 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 (0.74)%, meaning that over this time period UNL’s tracking error was within the plus or minus 10% range established as its benchmark tracking goal.

PAST PERFORMANCE IS NOT NECESSARILY INDICATIVE OF FUTURE RESULTS

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 year ended December 31, 2014, the actual total return of UNL as measured by changes in its per share NAV was (25.27)%. This is based on an initial per share NAV of $18.32 on December 31, 2013 and an ending per share NAV as of December 31, 2014 of $13.69. 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 $13.81 as of December 31, 2014, for a total return over the relevant time period of (24.62)%. The difference between the actual per share NAV total return of UNL of (25.27)% and the expected total return based on the Benchmark Futures Contracts of (24.62)% was an error over the time period of (0.65)%, 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. During the year ended December 31, 2014, UNL earned dividend and interest income of $5,086, which is equivalent to a weighted average income rate of approximately 0.03% for such period. In addition, during the year ended December 31, 2014, UNL also collected $5,600 from its Authorized Participants for creating or redeeming baskets of shares. This income also contributed to UNL’s actual total return. During the year ended December 31, 2014, UNL incurred net expenses of $178,677. Income from dividends and interest and Authorized Participant collections net of expenses was $(167,991), which is equivalent to a weighted average net income rate of approximately (0.88)% for the year ended December 31, 2014.

By comparison, for the year ended December 31, 2013, the actual total return of UNL as measured by changes in its per share NAV was 6.33%. This is based on an initial per share NAV of $17.23 on December 31, 2012 and an ending per share NAV as of December 31, 2013 of $18.32. 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 $18.48 as of December 31, 2013, for a total return over the relevant time period of 7.24%. The difference between the actual per share NAV total return of UNL of 6.33% and the expected total return based on the Benchmark Futures Contracts of 7.24% was an error over the time period of (0.91)%, 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. During the year ended December 31, 2013, UNL earned dividend and interest income of $9,200, which is equivalent to a weighted average income rate of approximately 0.03% for such period. In addition, during the year ended December 31, 2013, UNL also collected $9,450 from its Authorized Participants for creating or redeeming baskets of shares. This income also contributed to UNL’s actual total return. During the year ended December 31, 2013, UNL incurred net expenses of $320,978. Income from dividends and interest and Authorized Participant collections net of expenses was $(302,328), which is equivalent to a weighted average net income rate of approximately (0.91)% for the year ended December 31, 2013.

46

By comparison, for the year ended December 31, 2012, the actual total return of UNL as measured by changes in its per share NAV was (18.76)%. This was based on an initial per share NAV of $21.21 on December 31, 2011 and an ending per share NAV as of December 31, 2012 of $17.23. 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 $17.39 As of December 31, 2012, for a total return over the relevant time period of (18.01)%. The difference between the actual per share NAV total return of UNL of (18.76)% and the expected total return based on the Benchmark Futures Contracts of (18.01)% was an error over the time period of (0.75)%, 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 paid, offset in part by the income that UNL collected on its cash and cash equivalent holdings. During the year ended December 31, 2012, UNL earned dividend and interest income of $11,446, which is equivalent to a weighted average income rate of approximately 0.03% for such period. In addition, during the year ended December 31, 2012, UNL also collected $10,500 from its Authorized Participants for creating or redeeming baskets of shares. This income also contributed to UNL’s actual total return. During the year ended December 31, 2012, UNL incurred net expenses of $366,228. Income from dividends and interest and Authorized Participant collections net of expenses was $(344,282), which is equivalent to a weighted average net income rate of approximately (0.91)% for the year ended December 31, 2012.

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 daily changes in the 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 year ended December 31, 2014, 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.

Second, UNL incurs expenses primarily composed of the management fees, 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 average price of the Benchmark Futures Contracts. 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 year ended December 31, 2014. 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 Benchmark Futures Contracts. During the year ended December 31, 2014, UNL earned, on an annualized basis, approximately 0.03% on its cash and cash equivalent holdings. It also incurred cash expenses on an annualized basis of (0.75)% for management fees, approximately (0.02)% in brokerage commission costs related to the purchase and sale of Futures Contracts, and approximately (0.51)% for other expenses. The foregoing fees and expenses, net of other income and reimbursements, resulted in a net yield on an annualized basis of approximately (0.90)% and affected UNL’s ability to track its benchmark. If short-term interest rates rise above the current levels, the level of deviation created by the yield would decrease. Conversely, if short-term interest rates were to decline, the amount of error created by the yield would increase. When short-term yields drop to a level lower than the combined expenses of the management fee and the brokerage commissions, then the tracking error becomes a negative number and would tend to cause the daily returns of the per 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 time when interest earned at least equals or exceeds the fees and expenses paid by UNL.

47

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 year ended December 31, 2014, 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 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.

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.

PAST PERFORMANCE IS NOT NECESSARILY INDICATIVE OF FUTURE RESULTS

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 December 31, 2004 and December 31, 2014. Investors will note that the natural gas market spent time in both backwardation and contango.

PAST PERFORMANCE IS NOT NECESSARILY INDICATIVE OF FUTURE RESULTS

An investment in a portfolio that involved owning only the near month contract would likely produce a different result than an investment in a portfolio that owned an equal number of each of the near 12 months’ worth of contracts. Generally speaking, when the 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 twelfth 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.

51

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 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. While the investment objective of UNL is not to have the market price of its shares match, dollar for dollar, changes in the spot price of natural gas, contango impacted the total return on an investment in UNL shares during the year ended December 31, 2014 relative to a hypothetical direct investment in natural gas. For example, an investment in UNL shares made on December 31, 2013 and held to December 31, 2014 decreased, based upon the changes in the NAV for UNL shares on those days, by approximately 25.27%, while the spot price of natural gas for immediate delivery during the same period decreased by approximately 27.01% (note: this comparison ignores the potential costs associated with physically owning and storing natural gas, which could be substantial). By comparison, an investment in UNL shares made on December 31, 2012 and held to December 31, 2013 increased, based upon the changes in the NAV for UNL shares on those days, by approximately 6.33%, while the spot price of natural gas for immediate delivery during the same period increased by approximately 16.33% (note: this comparison ignores the potential costs associated with physically owning and storing natural gas, which could be substantial).

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 price 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 year ended December 31, 2014, 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. Colder weather in some parts of the country during the early months of 2014 increased demand for natural gas, while a historic storage surplus that had weighed on prices in recent years fell below the five-year average and 2013 levels. From April through October, strong weekly supply injections allowed inventory levels to recover, and a combination of warmer weather and weak storage withdraws heading into the winter resulted in inventories returning to approximate 5-year average levels. As of December 31, 2014, the amount of natural gas in storage had reached 3,089 billion cubic feet, which was approximately 2.1% below the five-year average and 0.09% above 2013 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.

52

For the ten year time period between 2004 and 2014, 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 or 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 the one year period ended December 31, 2014, the movement of natural gas on a monthly basis remained neither strongly correlated, nor inversely correlated with large-cap U.S. equities, global equities, crude oil or unleaded gasoline. However, movements in natural gas were correlated with U.S. government bonds and diesel-heating oil.

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 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 futures contracts do not closely correlate with the natural gas Futures Contracts, then their use could lead to greater tracking error. As noted, 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 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 financial statements and related disclosures and has determined that the valuation of its investments which are not traded on a United States or internationally recognized futures exchange (such as forward contracts and over-the-counter contracts) involves a critical accounting policy. The values which are used by UNL for its Futures Contracts are provided by its commodity broker who uses market prices when available, while over-the-counter contracts are valued based on the present value of estimated future cash flows that would be received from or paid to a third party in settlement of these derivative contracts prior to their delivery date and valued on a daily basis. In addition, UNL estimates dividend and interest 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.

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 over-the-counter contracts and, if applicable, payment of its expenses, summarized below under “Contractual Obligations.”

UNL currently generates cash primarily from: (i) the sale of 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 Futures Contracts and Other Natural Gas-Related Investments. A significant portion of UNL’s NAV is held in Treasuries, 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 the Custodian 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 year ended December 31, 2014, UNL’s expenses did not exceed the income UNL earned and the cash earned from the sales of Creation Baskets. During the year ended December 31, 2013, UNL’s expenses exceeded the income UNL earned and the cash earned from the sale of Creation Baskets and 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 was negatively impacted.

54

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 futures contracts. During the year ended December 31, 2014, 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 by USCF. USCF has voluntary agreed to pay certain expenses typically borne by UNL, to the extent that such expenses exceeded 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 payment into subsequent periods. UNL will be 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. 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 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 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.

Credit Risk

When UNL enters into 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 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.

55

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 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 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 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 Futures Contracts trading.

In the future, UNL may purchase over-the-counter contracts. See “Item 7A. Quantitative and Qualitative Disclosures About Market Risk” in this annual report on Form 10-K for a discussion of over-the-counter contracts.

As of December 31, 2014, UNL held cash deposits and investments in Treasuries and money market funds in the amount of $20,638,619 with the Custodian and FCM. Some or all of these amounts may be subject to loss should the Custodian and/or FCM cease operations.

Off Balance Sheet Financing

As of December 31, 2014, 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 December 31, 2014 and has no direct exposure to European sovereign debt as of the filing of this annual report on Form 10-K.

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.

USCF pays the fees of the Marketing Agent and the fees of the Custodian and Transfer Agent, BBH&Co., as well as BBH&Co.’s fees for performing administrative services, including those in connection with the preparation of UNL’s 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, USAG and USMI, pay a licensing fee to the NYMEX. UNL also pays the fees and expenses associated with its tax accounting and reporting requirements. USCF has voluntarily agreed to pay certain expenses typically borne by UNL, to the extent that such expenses exceeded 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 payment 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 8 of this annual report on Form 10-K.

In addition to USCF’s management fee, UNL pays its brokerage fees (including fees to a FCM), over-the-counter dealer spreads, any licensing fees for the use of intellectual property, and, subsequent to the initial offering, registration and other fees paid to the SEC, FINRA, or other regulatory agencies in connection with the offer and sale of 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 Financial Statements in Item 8 of this annual report on Form 10-K.

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 December 31, 2014, UNL’s portfolio consisted of 537 Natural Gas Futures NG Contracts traded on the NYMEX. As of December 31, 2014, UNL did not hold any Futures Contracts traded on ICE Futures. For a list of UNL’s current holdings, please see UNL’s website at www.unitedstatescommodityfunds.com.

Item 7A. | Quantitative and Qualitative Disclosures About Market Risk

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

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

UNL may enter into certain transactions where an over-the-counter component is exchanged for a corresponding futures contract (“Exchange for Related Position” or “EFRP” transactions). In the most common type of EFRP transaction entered into by UNL, the over-the-counter component is the purchase or sale of one or more baskets of UNL’s shares. These EFRP transactions may expose UNL to counterparty risk during the interim period between the execution of the over-the-counter component and the exchange for a corresponding futures contract. Generally, the counterparty risk from the EFRP 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.

57

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 ISDA 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.

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. 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 12 month reporting period ended December 31, 2014, UNL limited its over-the-counter activities to EFRP transactions.

Management’s Annual Report on Internal Control Over Financial Reporting.

USCF assessed the effectiveness of UNL’s internal control over financial reporting as of December 31, 2014. In making this assessment, it used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control Integrated Framework. Based on the assessment, USCF believes that, as of December 31, 2014, UNL’s internal control over financial reporting is effective.

United States 12 Month Natural Gas Fund, LP

Notes to Financial Statements

For the years ended December 31, 2014, 2013 and 2012

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 spot 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 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 contracts that are the next month contract to expire and the contracts for the following 11 consecutive months (the “Benchmark Futures Contracts”), less UNL’s expenses. 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 contract 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 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, crude oil, diesel-heating oil, gasoline and other petroleum-based fuels that are traded on the NYMEX, ICE Futures or other U.S. and foreign exchanges (collectively, “Futures Contracts”) and other natural gas-related investments such as cash-settled options on Futures Contracts, forward contracts for natural gas, cleared swap contracts and over-the-counter transactions that are based on the price of natural gas, crude oil and other petroleum-based fuels, Futures Contracts and indices based on the foregoing (collectively, “Other Natural Gas-Related Investments”). As of December 31, 2014, UNL held 537 Futures Contracts for natural gas traded on the NYMEX and did not hold any 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. USCF is also the general partner of the United States Oil Fund, LP (“USO”), the United States Natural Gas Fund, LP (“UNL”), 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 AMEX under the ticker symbols “USO” on April 10, 2006, “UNL” 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 American Stock Exchange (the “AMEX”) by NYSE Euronext, each of USO’s, UNL’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 the 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”), the United States Agriculture Index Fund (“USAG”) and the United States Metals Index Fund (“USMI”), each a series of the United States Commodity Index Funds Trust. USCI, CPER, USAG and USMI listed their shares on the NYSE Arca under the ticker symbol “USCI” on August 10, 2010, “CPER” on November 15, 2011, “USAG” on April 13, 2012 and “USMI” on June 19, 2012, respectively. All funds listed previously are referred to collectively herein as the “Related Public Funds.” On January 30, 2015, USCF as the sponsor of United States Commodity Index Funds Trust (the “Trust”) and its series USMI announced that its officers and members had authorized a plan to (i) liquidate USMI, (ii) terminate the continuous offering of USMI, and (iii) deregister USMI under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and therefore, terminate the Trust’s obligation to include USMI on its periodic and current reports with the Securities and Exchange Commission (“SEC”). USCF has submitted written notice to the NYSE Arca of its decision to liquidate USMI, terminate the offering and to terminate USMI’s obligations under the Exchange Act.

68

USCF intends to file a post-effective amendment on behalf of the Trust and USMI to terminate the offering of the registered and unsold shares of USMI. The NYSE Arca will file a Form 25 with the SEC to affect the withdrawal of the listing of USMI from the NYSE Arca. Delisting from the NYSE Arca will become effective 10 days after the filing date of the Form 25. Provided that USMI continues to meet the applicable legal requirements, USCF intends to file a Form 15 on behalf of the Trust and USMI with the SEC in early April 2015 to suspend the Trust’s duty to include USMI on its reports under Sections 13(a) and 15(d) of the Exchange Act. USMI expects the termination of registration will become effective 90 days after the date of the filing of the Form 15 with the SEC.

UNL issues shares to certain authorized purchasers (“Authorized Participants”) by offering baskets consisting of 50,000 shares (“Creation Baskets”) through ALPS Distributors, Inc. as its marketing agent (“ALPS Distributors” or 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.

From July 1, 2011 through December 31, 2014 (and continuing at least through April 30, 2015), the applicable transaction fee paid by Authorized Participants is $350 to UNL for each order they place to create or redeem one or more baskets (“Redemption Baskets”); prior to July 1, 2011, this fee was $1,000. 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.

In November 2009, UNL initially registered 30,000,000 shares on Form S-1 with 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 Futures Contracts traded on the NYMEX based on natural gas. As of December 31, 2014, UNL had registered a total of 25,600,000 shares.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Revenue Recognition

Commodity futures contracts, forward contracts, physical commodities and related options are recorded on the trade date. All such transactions are recorded on the identified cost basis and marked to market daily. Unrealized gains or losses on open contracts are reflected in the statements of financial condition and represent the difference between the original contract amount and the market value (as determined by exchange settlement prices for futures contracts and related options and cash dealer prices at a predetermined time for forward contracts, physical commodities, and their related options) as of the last business day of the year or as of the last date of the financial statements. Changes in the unrealized gains or losses between periods are reflected in the statements of operations. UNL earns interest on its assets denominated in U.S. dollars on deposit with the futures commission merchant (“FCM”) at the overnight Federal Funds Rate less 32 basis points. 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.

69

In accordance with accounting principles generally accepted in the United States of America (“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 year ended December 31, 2014.

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 statements of financial condition as receivable for shares sold, and amounts payable to Authorized Participants upon redemption are reflected as payable for shares redeemed.

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 December 31, 2014.

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.

70

Reclassification

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

Use of Estimates

The preparation of 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 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, that is 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 years ended December 31, 2014, 2013 and 2012, UNL did not incur any registration fees and 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 fund, computed on a daily basis. These fees and expenses for the year ended December 31, 2014 were $567,863 for UNL and the Related Public Funds. UNL’s portion of such fees and expenses for the year ended December 31, 2014 was $6,009. For the years ended December 31, 2013 and 2012, these fees and expenses were $555,465 and $540,586, respectively, for UNL and the Related Public Funds. UNL’s portion of such fees and expenses was $7,620 and $5,705, respectively.

Licensing Fees

UNL and the Related Public Funds, other than BNO, USCI, CPER, USAG and USMI, pay a licensing fee that is equal to 0.015% on all net assets. During the years ended December 31, 2014, 2013 and 2012, UNL incurred $2,879, $5,001 and $5,674, 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 were approximately $86,000, $125,000 and $75,000, respectively, for the years ended December 31, 2014, 2013 and 2012.

71

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 below. USCF has voluntarily agreed to pay certain expenses typically borne by UNL, to the extent that such expenses exceeded 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 payment into subsequent periods. For the year ended December 31, 2014, USCF waived $ 128,906 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 ten percent (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 as of 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 futures commission merchant (“FCM”), effective October 10, 2013. Prior to October 10, 2013, the FCM was UBS Securities LLC (“UBS Securities”). The agreements require RBC Capital and UBS Securities to provide services to UNL in connection with the purchase and sale of 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 each agreement, RBC Capital and UBS Securities charge UNL commissions of approximately $7 to $15 per round-turn trade, including applicable exchange and NFA fees for Futures Contracts and options on Futures Contracts. Such fees include those incurred when purchasing Futures Contracts and options on Futures Contracts when UNL issues shares as a result of a Creation Basket, as well as fees incurred when selling Futures Contracts and options on Futures Contracts when UNL redeems shares as a result of a Redemption Basket. Such fees are also incurred when Futures Contracts and options on 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 Futures Contracts, Other Natural Gas-Related Investments or short term obligations of the United States of two years or less (“Treasuries”).

|  | For the Year Ended December 31, 2014 |  |  | For the Year Ended December 31, 2013 |  |  | For the Year Ended December 31, 2012 |
Total commissions accrued to brokers |  | $ | 3,918 |  |  | $ | 8,360 |  |  | $ | 14,360 |
Total commissions as annualized percentage of average total net assets |  |  | 0.02 | % |  |  | 0.03 | % |  |  | 0.04 | %

Percentage of commissions accrued as a result of creation and redemption activity |  |  | 45.74 | % |  |  | 46.36 | % |  |  | 23.43 | %

UNL’s total commissions accrued to brokers for the year ended December 31, 2104, compared to the year ended December 31, 2013, was similar; and was similar for the year ended December 31, 2013, compared to the year ended December 31, 2012, as measured as an annualized percentage of average total net assets. However, there can be no assurance that commission costs and portfolio turnover will not cause commission expenses to rise in future quarters.

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, USAG and USMI, 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 swap contracts (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 and options on futures contracts and may engage in cleared swap contracts to gain exposure to changes in the value of an underlying commodity. A futures contract obligates the seller to deliver (and the purchaser to accept) the future delivery of a specified quantity and type of a commodity at a specified time and place. Some futures contracts may call for physical delivery of the asset, while others are settled in cash. The contractual obligations of a buyer or seller may generally be satisfied by taking or making physical delivery of the underlying commodity or by making an offsetting sale or purchase of an identical futures contract on the same or linked exchange before the designated date of delivery. Cleared swaps are over-the-counter agreements that are eligible to be cleared by a clearinghouse, but are not traded on an exchange. A cleared swap is created when the parties to an off-exchange over-the-counter swap transaction agree to extinguish their OTC contract and replace with a cleared swap. Cleared swaps are intended to provide the efficiencies and benefits that centralized clearing or 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 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. 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.

73

All of the Futures Contracts held by UNL were exchange-traded futures contracts through December 31, 2014. The risks associated with exchange-traded contracts are generally perceived to be less than those associated with over-the-counter transactions, since, in over-the-counter transactions, a party must rely solely on the credit of its respective individual counterparties. When UNL enters into non-exchange traded contracts (including Exchange for Related Position or EFRP transactions), it is subject to credit risks associated with counterparty non-performance. Over-the-counter 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 December 31, 2014 and December 31, 2013, UNL held investments in money market funds in the amounts of $9,510,692 and $19,522,574, 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 December 31, 2014 and December 31, 2013, UNL held cash deposits and investments in Treasuries in the amounts of $11,127,927 and $6,941,097, 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 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 8 - 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 December 31, 2014 using the fair value hierarchy:

At December 31, 2014 |  | Total |  |  | Level I |  |  | Level II |  |  | Level III |
Short-Term Investments |  | $ | 12,510,147 |  |  | $ | 12,510,147 |  |  | $ | — |  |  | $ | — |
Exchange-Traded Futures Contracts |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
United States Contracts |  |  | (4,919,890 | ) |  |  | (4,919,890 | ) |  |  | — |  |  |  | — |

During the year ended December 31, 2014, there were no transfers between Level I and Level II.

The following table summarizes the valuation of UNL’s securities at December 31, 2013 using the fair value hierarchy:

At December 31, 2013 |  | Total |  |  | Level I |  |  | Level II |  |  | Level III |
Short-Term Investments |  | $ | 22,522,078 |  |  | $ | 22,522,078 |  |  | $ | — |  |  | $ | — |
Exchange-Traded Futures Contracts |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
United States Contracts |  |  | 1,090,050 |  |  |  | 1,090,050 |  |  |  | — |  |  |  | — |

During the year ended December 31, 2013, there were no transfers between Level I and Level II.

Effective January 1, 2009, UNL adopted the provisions of Accounting Standards Codification 815 – Derivatives and Hedging (“ASC 815”), which require presentation of qualitative disclosures about objectives and strategies for using derivatives, quantitative disclosures about fair value amounts and gains and losses on derivatives.

NOTE 9 - RECENT ACCOUNTING PRONOUNCEMENTS

In December 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2011-11, “Balance Sheet (Topic 210): Disclosures about Offsetting Assets and Liabilities.” The amendments in ASU No. 2011-11 require an entity to disclose information about offsetting and related arrangements to enable users of its financial statements to understand the effect of those arrangements on its financial position. ASU No. 2011-11 is effective for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods.

NOTE 10 - SUBSEQUENT EVENTS

UNL has performed an evaluation of subsequent events through the date the financial statements were issued. This evaluation did not result in any subsequent events that necessitated disclosures and/or adjustments other than noted below:

On January 14, 2015, Mr. Howard Mah, Management Director, Chief Financial Officer (Principal Accounting Officer), Secretary and Treasurer of USCF, general partner of United States 12 Month Natural Gas Fund, LP, tendered his resignation effective as soon as the Board of Directors of USCF accepts and appoints a suitable replacement, but no later than the close of business July 15, 2015. In order to ensure an orderly transition, Mr. Mah will remain as the Management Director and Chief Financial Officer (Principal Accounting Officer) of USCF until such time.

On January 26, 2015, Mr. Nicholas D. Gerber was appointed Chief Executive Officer, President and Secretary of Concierge Technologies, Inc. (“Concierge”), a supplier of mobile video recording devices through its wholly owned subsidiary Janus Cam. Concierge is not affiliated with USCF and the Related Public Funds, other than through ownership by common control. Concierge is a publicly traded company under the ticker symbol “CNCG.”

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the statements of financial condition are free of material misstatement. An audit includes consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the statements of financial condition, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall statement of financial condition presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of United States Commodity Funds LLC as of December 31, 2014 and 2013 in conformity with accounting principles generally accepted in the United States of America.

USL commenced investment operations on December 6, 2007 and has a fiscal year ending on December 31. The investment objective of USL is for the daily changes in percentage terms of its shares’ per share net asset value (“NAV”) to reflect the daily changes in percentage terms of the spot price of light, sweet crude oil delivered to Cushing, Oklahoma, as measured by the daily changes in the average of the prices of the 12 futures contracts for light, sweet crude oil traded on the New York Mercantile Exchange (the “NYMEX”), consisting of the near month contract to expire and the contracts for the following 11 months for a total of 12 consecutive months’ contracts, except when the near month contract is within two weeks of expiration, in which case it will be measured by the futures contract that is the next month contract to expire and the contracts for the following 11 consecutive months (the “Benchmark Oil Futures Contracts”), less USL’s expenses.

USCI commenced investment operations on August 10, 2010 and has a fiscal year ending on December 31. The investment objective of USCI is for the daily changes in percentage terms of its shares’ per share Net Asset Value (“NAV”) to reflect the daily changes in percentage terms of the SummerHaven Dynamic Commodity Index Total ReturnSM (the “SDCI”), less USCI’s expenses. The SDCI is comprised of 14 Futures Contracts that are selected on a monthly basis from a list of 27 possible Futures Contracts. The Futures Contracts that at any given time make up the SDCI are referred to herein as “Benchmark Component Futures Contracts. USCI invests first in the current Benchmark Component Futures Contracts and other Futures Contracts intended to replicate the return on the current Benchmark Component Futures Contracts and, thereafter may hold Futures Contracts in a particular commodity other than one specified as the Benchmark Component Futures Contract, or may hold Other Commodity-Related Investments that are intended to replicate the return on the Benchmark Futures Contracts, but may fail to closely track the SDCI’s total return movements. If USCI increases in size, and due to its obligations to comply with regulatory limits or due to other market pricing or liquidity factors, USCI may invest in Futures Contract months other than the designated month specified as the Benchmark Component Futures Contract, or in Other Commodity-Related Investments, which may have the effect of increasing transaction related expenses and may result in increased tracking error.

CPER commenced investment operations on November 11, 2011 and has a fiscal year ending on December 31. The investment objective of CPER is for the daily changes in percentage terms of its shares’ per share NAV to reflect the daily changes in percentage terms of the SummerHaven Copper Index Total ReturnSM (the “SCI”), less CPER’s expenses. The SCI is comprised of either two or three Eligible Copper Futures Contracts that are selected on a monthly basis based on quantitative formulas relating to the prices of the Eligible Copper Futures Contracts developed by SHIM. The Eligible Copper Futures Contracts that at any given time make up the SCI are referred to herein as “Benchmark Component Copper Futures Contracts.” CPER seeks to achieve its investment objective by investing to the fullest extent possible in the Benchmark Component Copper Futures Contracts. Then, if constrained by regulatory requirements or in view of market conditions, CPER will invest next in other Eligible Copper Futures Contracts, and finally to a lesser extent, in other exchange traded futures contracts that are economically identical or substantially similar to the Benchmark Component Copper Futures Contracts if one or more other Eligible Copper Futures Contracts is not available. When CPER has invested to the fullest extent possible in exchange-traded futures contracts, CPER may then invest in other contracts and instruments based on the Benchmark Component Copper Futures Contracts, other Eligible Copper Futures Contracts or copper, such as cash-settled options, forward contracts, cleared swap contracts and swap contracts other than cleared swap contracts.

USAG commenced investment operations on April 13, 2012 and has a fiscal year ending on December 31.

Futures contracts for the agricultural commodities comprising the SDAI are traded on ICE Future US, ICE Futures Canada, the CBOT, the Kansas City Board of Trade (“KCBT”) and the CME and are collectively referred to herein as “Eligible Agriculture Futures Contracts.” The SDAI is comprised of 14 Eligible Agriculture Futures Contracts that are selected on a monthly basis based on quantitative formulas developed by SHIM. USAG seeks to achieve its investment objective by investing to the fullest extent possible in the Benchmark Component Agriculture Futures Contracts. Then, if constrained by regulatory requirements or in view of market conditions, USAG will invest next in other Eligible Agriculture Futures Contracts based on the same agricultural commodity as the futures contracts subject to such regulatory constraints or market conditions, and finally, to a lesser extent, in other exchange traded futures contracts that are economically identical or substantially similar to the Benchmark Component Agriculture Futures Contracts if one or more other Eligible Agriculture Futures Contracts is not available. When USAG has invested to the fullest extent possible in exchange-traded futures contracts, USAG may then invest in other contracts and instruments based on the Benchmark Component Agriculture Futures Contracts, other Eligible Agriculture Futures Contracts or the agricultural commodities included in the SDAI, such as cash-settled options, forward contracts, cleared swap contracts and swap contracts other than cleared swap contracts.

Revenue recognition

The Company recognizes revenue in the period earned under the terms of the Funds’ respective Limited Partnership Agreements, as amended from time to time (the “Limited Partnership Agreements”) and the Trust Agreement, as amended from time to time (the “Trust Agreement”). These Agreements provide for fees based upon a percentage of the daily average net asset value of the Funds. In connection with the Funds’ trading activities, commodity futures contracts, cleared swap contracts, forward contracts, physical commodities, and related options are recorded on the trade-date basis. All such transactions are recorded on the identified cost basis and marked to market daily. Unrealized gains and losses on open contracts are reflected in the statement of financial condition and represent the difference between original contract amount and market value (as determined by exchange settlement prices for futures contracts and related options and cash dealer prices at a predetermined time for forward contracts, physical commodities, and their related options) as of the last business day of the year or as of the last date of the financial statements. Changes in the unrealized gains or losses between periods are reflected in the statement of operations.

The Company earns interest on its assets on deposit at the broker at the 90-day Treasury bill rate for deposits denominated in U.S. dollars. In addition, the Funds earn interest on funds held with their custodian at prevailing market rates earned on such investments.

Management fee

Under the Funds’ respective Agreements, the Company is responsible for investing the assets of the Funds in accordance with the objectives and policies of the Funds. In addition, the Company has arranged for one or more third parties to provide administrative, custody, accounting, transfer agency and other necessary services to the Funds. For these services, the Funds are contractually obligated to pay the Company a management fee, which is paid monthly, based on the average daily net assets of the Funds. USO pays a management fee of 0.45% per annum on its average daily net assets. UNG pays a fee equal to 0.60% per annum on average daily net assets of $1,000,000,000 or less and 0.50% of average daily net assets that are greater than $1,000,000,000. USL, UGA, UHN, and DNO each pay a fee of 0.60% per annum on their average daily net assets. Since inception through April 30, 2010 the Company has been charging UNL a management fee at a reduced rate of 0.60% per annum of average daily net assets. Effective May 1, 2010, the Company resumed charging UNL its standard rate of 0.75% per annum of average daily net assets. The difference of 0.15% per annum of average daily net assets since inception through April 30, 2010 has been waived by the Company and will not be recouped from UNL. BNO pays a management fee of 0.75% per annum on its average daily net assets. Effective May 1, 2014 and continuing through December 31, 2015, the Company has contractually agreed to lower the management fee for USCI to 0.80%, 0.65% for CPER, 0.65% for USAG and 0.65% for USMI, per annum on its average daily net assets.

The Funds pay for all brokerage fees, taxes and other expenses, including registration or other fees paid to the SEC, the Financial Industry Regulatory Authority (“FINRA”) formerly the National Association of Securities Dealers, or any other regulatory agency in connection with the offer and sale of subsequent shares after their initial registration and all legal, accounting, printing and other expenses associated therewith.

Investments and Valuation of Investments

The Company’s investments in common stock are classified as available-for-sale-securities and are considered to be held for an indefinite period. Securities investments not classified as either held-to-maturity or trading securities are classified as available-for-sale securities. Available-for-sale-securities are recorded at fair value on the statement of financial condition, with the change in fair value excluded from earnings and recorded as a component of other comprehensive income (loss) included in member’s equity. Unrealized holding gains or losses on such securities, which were added to or subtracted from member’s equity was $552,571 and $6,820, for the years ended December 31, 2014 and 2013 (see Note 7).

Realized gains or losses are recorded upon disposition of investments calculated based upon the difference between the proceeds and the cost basis determined using the specific identification method.

The Company values its investments in accordance with FASB Accounting Standards Codification Topic 820, Fair Value Measurements and Disclosures (“FASB ASC Topic 820”). FASB ASC Topic 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 FASB ASC Topic 820 relate to the definition of fair value, the methods used to measure fair value, and the expanded disclosures about fair value measurement. FASB ASC Topic 820 establishes a fair value hierarchy that distinguishes between (1) market participant assumptions developed based on market data obtained from sources independent of the Company (observable inputs) and (2) the Company’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 FASB ASC Topic 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 1 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 in 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 Company’s adoption of FASB ASC Topic 820 did not have a material effect on its consolidated financial position, results of operations or liquidity.

In March 2008, the FASB released FASB ASC Topic 815-10, Disclosures about Derivative Instruments and Hedging Activities. FASB ASC Topic 815-10 requires qualitative disclosures about objectives and strategies for using derivatives, quantitative disclosures about fair value amounts of and gains and losses on derivative instruments, and disclosures about credit-risk-related contingent features in derivative agreements.

Brokerage commissions

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

Additions and redemptions

Authorized purchasers may purchase creation baskets of the Funds only in blocks of 100,000 shares at a price equal to the net asset value of the shares calculated shortly after the close of the core trading sessions on the NYSE Arca on the day the order is placed. Authorized purchasers may redeem shares from the Funds only in blocks of 100,000 shares called “Redemption Baskets.” Effective as of February 29, 2012, the size of the Creation Basket and Redemption Basket was reduced from 100,000 shares to 50,000 shares for USL, UGA, UHN, DNO, UNL and BNO. The amount of the redemption proceeds for a Redemption Basket will be equal to the net asset value of the Funds’ shares in the Redemption Basket as of the end of each business day.

The Funds receive or pay 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 purchasers are reflected in the Funds’ statement of financial condition as receivables for shares sold, and amounts payable to authorized purchasers upon redemption are reflected as payable for shares redeemed.

Capital and allocation of income and losses

Profit or loss shall be allocated among the shareholders of the Funds in proportion to the number of shares each shareholder holds as of the close of each month. The Company, when it serves in a capacity as a General Partner or Sponsor, may revise, alter or otherwise modify this method of allocation as described in the Limited Partnership Agreements or Trust Agreement.

Calculation of net asset value

The Funds calculate their net asset value on each NYSE Arca trading day by taking the current market value of their total assets, subtracting any liabilities and dividing the amount by the total number of shares issued and outstanding. The Funds use the closing price for the contracts on the relevant exchange on that day to determine the value of contracts held on such exchange.

Cash equivalents

Cash equivalents are highly liquid investments with original maturity dates of three months or less.

Accounting estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Income taxes

The Company has filed an election with the Internal Revenue Service to be treated as an association taxable as a corporation. The Company files a consolidated federal income tax return with Wainwright and provides for income taxes as if the Company filed separately. The Company, however, does not file on a consolidated basis for state income tax purposes. The Company accounts for income taxes in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Classification (“ASC”) Topic 740-10, Accounting for Income Taxes (“FASB ASC Topic 740-10”). Under the asset and liability method of FASB ASC Topic 740-10, deferred tax assets and liabilities are recognized for the estimated future tax consequences or benefits attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using the enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled.

Effective January 1, 2008, the Company adopted FASB ASC Topic 740-10, Accounting for Uncertainty in Income Taxes (“FASB ASC Topic 740-10”), which establishes that a tax position taken or expected to be taken in a tax return is to be recognized in the consolidated financial statements when it is more likely than not, based on the technical merits, that the position will be sustained upon examination. FASB ASC Topic 740-10 is effective for private companies for fiscal years beginning after December 15, 2008. The Company’s adoption of FASB ASC Topic 740-10 did not have a material effect on its consolidated financial position, results of operations or liquidity.

Fund startup expenses

The Company expenses all startup expenses associated with the registration of each fund. Fund startup expenses include offering costs relating to the initial registration of sharesand include, but are not limited to, legal fees pertaining to the initial registration of shares, SEC and FINRA registration fees, initial fees paid to be listed on an exchange and other similar costs.

Recent accounting pronouncements

In December 2009, the FASB issued ASU 2009-17, Consolidations (Topic 810) – Improvements to Financial Reporting by Enterprises Involved with Variable Interest Entities. This ASU changes how a reporting entity determines when an entity that is insufficiently capitalized or is not controlled through voting (or similar rights) should be consolidated. ASU 2009-17 also requires a reporting entity to provide additional disclosures about its involvement with variable interest entities and any significant changes in risk exposure due to that involvement. ASU 2009-17 is effective at the start of a reporting entity’s first fiscal year beginning after November 15, 2009.

In February 2010, the FASB issued ASU 2010-10, Consolidation (Topic 810) – Amendments for Certain Investment Funds. This ASU amends certain provisions of ASC 810 pertaining to investments in variable interest entities to defer the effective date of ASU 2009-17 for certain investment entities and changes how decision makers and service providers determine whether their fees are variable interests. The amendments in ASU 2010-10 are effective as of the beginning of a reporting entity’s first annual period that begins after November 15, 2009, and for interim periods within that first annual reporting period. The adoption of ASU 2010-10 did not have a material impact on the Company’s financial position.

In January 2010, the FASB issued ASU 2010-06, Fair Value Measurements and Disclosures (Topic 820) – Improving Disclosures about Fair Value Measurements. This ASU requires new disclosures and clarifies certain existing disclosure requirements about fair value measurements. ASU 2010-06 requires a reporting entity to disclose significant transfers in and out of Level 1 and Level 2 fair value measurements, to describe the reasons for the transfers, and to present separately information about purchases, sales, issuances, and settlements for fair value measurements using significant unobservable inputs. ASU 2010-05 is effective for interim and annual reporting periods beginning after December 15, 2009, except for the disclosures about purchases, sales, issuances, and settlements in the roll forward of activity in Level 3 fair value measurements, which is effective for interim and annual reporting periods beginning after December 15, 2010; early adoption is permitted.

For their services, the Company pays SummerHaven an advisory fee for USCI equal to a percentage of the average daily assets of USCI that is equal to the percentage paid to USCF by USCI minus 0.14% with that result multiplied by 0.5 minus 0.06%. The Company also pays an advisory fee for CPER, USAG and USMI equal to a percentage of the average daily assets of CPER, USAG and USMI that is equal to the percentage paid to the Company by CPER, USAG and USMI minus 0.18% with that result multiplied by 0.5 minus 0.06%. The Company also pays SummerHaven a sublicense fee for the use of the SDCI, SCITR, SDAI and SDMI. For each of USCI, CPER, USAG and USMI the Company paid $15,000 for the calendar year 2014, plus an annual fee of 0.06% of the average daily assets of each of USCI, CPER, USAG and USMI.

Each of the Funds, with the exception of USCI, CPER, USAG and USMI, has entered into brokerage agreements pursuant to which RBC Capital Markets, LLC act as the futures commission merchants (the “FCM”); Wells Fargo Securities, LLC acts as the FCM for USCI, CPER, USAG and USMI. The agreements provide that the FCM will charge commissions of approximately $7 to $8 per round-turn trade plus applicable exchange and NFA fees for futures contracts and options on futures contracts.

Each of the Funds, other than BNO, USCI, CPER, USAG and USMI, has invested primarily in futures contracts traded on the Exchange since the commencement of its operations. The Funds, other than BNO, USCI, CPER, USAG and USMI, have entered into a license agreement with the Exchange whereby the Funds were granted a non-exclusive license to use certain of the Exchange’s settlement prices and service marks. Up to October 19, 2011, the Funds, other than BNO, USCI, CPER, USAG and USMI, paid a licensing fee that was equal to 0.04% for the first $1,000,000,000 of combined assets of the Funds and 0.02% for combined assets above $1,000,000,000. On and after October 20, 2011, the Funds, other than BNO, USCI, CPER, USAG and USMI, pay a licensing fee that is equal to 0.015% on all assets.

The Funds expressly disclaim any association with the Exchange or endorsement of the Funds by the Exchange and acknowledge that “NYMEX” and “New York Mercantile Exchange” are registered trademarks of such Exchange.

The Company has contracted an accounting firm to prepare each of the Funds and the Trust’s yearly income tax filings with the Internal Revenue Service and various states. The cost associated with any registered new fund is expected to be comparable.

| NOTE 7 - | ACCUMULATED OTHER COMPREHENSIVE LOSS

Changes in accumulated other comprehensive loss for the years ended December 31, 2014 and 2013 are as follows:

Balance, December 31, 2012 |  | $ | (559,391 | )
Unrealized holding gains on investments |  |  | 6,820 |

The Company records its other comprehensive loss net of income tax expense (benefit). As of December 31, 2014 and 2013, the Company has not recorded an income tax expense or benefit associated with its accumulated other comprehensive loss (see Note 5).

| NOTE 8 - | OFF-BALANCE SHEET RISKS AND CONTINGENCIES

The Funds engage in the trading of U.S. futures contracts, options on U.S. contracts, cleared swap contracts and over-the-counter derivative transactions (collectively “derivatives”). The Funds are exposed to both market risk, the risk arising from changes in the market value of the contracts; and credit risk, the risk of failure by another party to perform according to the terms of a contract.

All of the contracts currently traded by the Funds, with the exception of USNG, are exchange-traded. The risks associated with exchange-traded contracts are generally perceived to be less than those associated with over-the-counter transactions since, in over-the-counter transactions, the Funds must rely solely on the credit of their respective individual counterparties. To the extent the Funds enter into non-exchange traded contracts, they are subject to the credit risk associated with counterparty non-performance. The credit risk from counterparty non-performance associated with such instruments is the net unrealized gain, if any. The Funds also have credit risk since the sole counterparty to all domestic futures contracts is the exchange clearing corporation. In addition, the Funds bear the risk of financial failure by the clearing broker.

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

NOTES TO CONSOLIDATED STATEMENTS OF FINANCIAL CONDITION

| NOTE 8 - | OFF-BALANCE SHEET RISKS AND CONTINGENCIES (concluded)

A customer’s cash and other property, such as U.S. Treasury Bills, deposited with an FCM are considered commingled with all other customer funds subject to the FCM’s segregation requirements. In the event of an FCM’s insolvency, recovery may be limited to a pro rata share of segregated funds available. It is possible that the recovered amount could be less than the total of cash and other property deposited.

For derivatives, risks arise from changes in the market value of the contracts. Theoretically, the Funds are exposed to market risk equal to the value of futures and forward contracts purchased and unlimited liability on such contracts sold short. As both buyers and sellers of options, the Funds pay or receive a premium at the outset and then bear the risk of unfavorable changes in the price of the contract underlying the option.

The Company’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 and control procedures. In addition, the Company has a policy of reviewing the credit standing of each clearing broker or counter-party with which it conducts business.

The financial instruments held by the Company are reported in the statement 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 maturities.

The Company has securities for its own account and may incur losses if the market value of the securities decreases subsequent to December 31, 2014.

The Company has a substantial portion of its assets on deposit with banks. Assets deposited with banks are subject to credit risk. In the event of a bank's insolvency, recovery of the Company's assets on deposit may be limited to account insurance or other protection afforded such deposits. As of December 31, 2014, the Company had cash of $870,123 in excess of the federally insured amount of $250,000.

| NOTE 9 - | SUBSEQUENT EVENTS

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 Exchange Act 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 annual report on Form 10-K.

Management’s Annual Report on Internal Control Over Financial Reporting

UNL is responsible for establishing and maintaining adequate internal control over financial reporting. UNL’s internal control system is designed to provide reasonable assurance to USCF and the Board of USCF regarding the preparation and fair presentation of published financial statements. All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation. USCF’s report on internal control over financial reporting is set forth above under the heading, “Management’s Annual Report on Internal Control Over Financial Reporting” in Item 8 of this annual report on Form 10-K.

Change in Internal Control Over Financial Reporting

There were no changes in UNL’s internal control over financial reporting during UNL’s last fiscal quarter that have materially affected, or are reasonably likely to materially affect, UNL’s internal control over financial reporting.

Audit Committee

The Board of USCF has an audit committee which is made up of the three independent directors (Gordon L. Ellis, Malcolm R. Fobes III and Peter M. Robinson). Mr. Fobes currently serves as chair of the Audit Committee. The audit committee is governed by an audit committee charter that is posted on UNL’s website at www.unitedstatescommodityfunds.com. Any shareholder of UNL may also obtain a printed copy of the audit committee charter, free of charge, by calling 1-800-920-0259. The Board has determined that each member of the audit committee meets the financial literacy requirements of the NYSE Arca and the audit committee charter. The Board has further determined that each of Messrs. Ellis and Fobes have accounting or related financial management expertise, as required by the NYSE Arca, such that each of them is considered an “Audit Committee Financial Expert” as such term is defined in Item 407(d)(5) of Regulation S-K.

Other Committees

Since the individuals who perform work on behalf of UNL are not compensated by UNL, but instead by USCF, UNL does not have a compensation committee. Similarly, since the directors noted above serve on the Board of USCF, there is no nominating committee of the Board that acts on behalf of UNL. USCF believes that it is necessary for each member of the Board to possess many qualities and skills. USCF further believes that all directors should possess a considerable amount of business management and educational experience. There have not been any vacancies on USCF’s Board since the commencement of operations of USO in April 2006; however, if such a vacancy were to occur, the members of the Board would consider a candidate’s management experience as well as his/her background, stature, conflicts of interest, integrity and ethics. In connection with this, the Board would also consider issues of diversity, such as diversity of gender, race and national origin, education, professional experience and differences in viewpoints and skills. The Board does not have a formal policy with respect to diversity; however, the Board believes that it is essential that the Board represent diverse viewpoints.

Corporate Governance Policy

The Board of USCF has adopted a Corporate Governance Policy that applies to UNL and the Related Public Funds. UNL has posted the text of the Corporate Governance Policy on its website at www.unitedstatescommodityfunds.com. Any shareholder of UNL may also obtain a printed copy of the Corporate Governance Policy, free of charge, by calling 1-800-920-0259.

Code of Ethics

USCF has adopted a Code of Business Conduct and Ethics (the “Code of Ethics”) that applies to its principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions, and also to UNL. UNL has posted the text of the Code of Ethics on its website at www.unitedstatescommodityfunds.com. Any shareholder of UNL may also obtain a printed copy of the Code of Ethics, free of charge, by calling 1-800-920-0259. UNL intends to disclose any amendments or waivers to the Code of Ethics applicable to USCF’s principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions, on its website.

99

Executive Sessions of the Non-Management Directors

In accordance with the Corporate Governance Policy of USCF, the non-management directors of the Board (who are the same as the independent directors of the Board) meet separately from the other directors in regularly scheduled executive sessions, without the presence of Management Directors or executive officers of USCF. The non-management directors have designated Gordon L. Ellis to preside over each such executive session. Interested parties who wish to make their concerns known to the non-management directors may communicate directly with Mr. Ellis by writing to 475 Milan Drive, No. 103, San Jose, CA 95134-2453 or by e-mail at uscf.director@gmail.com.

Board Leadership Structure and Role in Risk Oversight

The Board of USCF is led by a Chairman, Nicholas Gerber, who is also the President and CEO of USCF. The Board’s responsibilities include (i) the selection, evaluation, retention and succession of the Chief Executive Officer and the oversight of the selection and performance of other executive officers, (ii) understanding, reviewing and monitoring the implementation of strategic plans, annual operating plans and budgets, (iii) the selection and oversight of UNL’s independent auditors and the oversight of UNL’s financial statements, (iv) advising management on significant issues, (v) the review and approval of significant company actions and certain other matters, (vi) nominating directors and committee members and overseeing effective corporate governance and (vii) the consideration of other constituencies, such as USCF’s and UNL’s customers, employees, suppliers and the communities impacted by UNL. The non-management directors have designated Gordon L. Ellis as the presiding independent director. Mr. Ellis’ role as the presiding independent director includes presiding over each executive session of the non-management directors, facilitating communications by shareholders and employees with the non-management directors and may also include representing the non-management directors with respect to certain matters as to which the views of the non-management directors are sought pursuant to UNL’s Corporate Governance Policy.

The Board believes that Mr. Gerber is best situated to serve as Chairman of USCF because he is the director most familiar with the business of USCF, including investing in the futures contracts and other commodity interests in order to track the benchmark futures contracts of UNL and the Related Public Funds. Because of his background, he is most capable of effectively leading the discussion and execution of new strategic objectives. The independent directors of USCF are actively involved in the oversight of USCF and, because of their varied backgrounds, provide different perspectives in connection with the oversight of USCF, UNL and the Related Public Funds. USCF’s independent directors bring expertise from outside USCF and the commodities industry, while Mr. Gerber brings company-specific and industry-specific experience and expertise. The Board believes that the combined role of Chairman and Chief Executive Officer facilitates information flow between USCF and the Board, including the independent directors, which is essential to effective governance.

Risk Management

The full Board is actively involved in overseeing the management and operation of USCF, including oversight of the risks that face UNL and the Related Public Funds. For example, the Board has adopted an Investment Policy and a Policy for Use of Derivatives. The policies are intended to ensure that USCF takes prudent and careful action while entering into and managing investments taken by UNL, including Futures Contracts or Other Natural Gas-Related Investments such as over-the-counter swap contracts. Additionally, the policies are intended to provide assurance that there is sufficient flexibility in controlling risks and returns associated with the use of investments by UNL. The policies, among other things, limit UNL’s ability to have too high of a concentration of its assets in non-exchange traded futures contracts or cleared swap contracts or concentrating its investments in too few counterparties, absent prior approval from the Board. Existing counterparties are reviewed periodically by the Board to ensure that they continue to meet the criteria outlined in the policies. The Board tasks USCF with assessing risks, including market risk, credit risk, liquidity risk, cash flow risk, basis risk, legal and tax risk, settlement risk, and operational risk.

100

The Board also determines compensation payable to employees of USCF, including the portfolio managers of each of UNL and the Related Public Funds. The compensation of certain employees of USCF is, in part, based on the amount of assets under management by UNL and the Related Public Funds. The Board feels that compensating certain employees, in part, based on the amount of assets under management is appropriate since having more assets in a fund generally reflects that investors perceive the fund’s investment objective is being met. There are certain risks that may arise as a result of a growth in assets under management. For example, if position limits are imposed on UNL and the assets under management continue to increase, then UNL may not be able to invest solely in the Benchmark Futures Contracts and may have to invest in over-the-counter swap contracts or Other Natural Gas-Related Investments as it seeks to track its benchmark. Other Futures Contracts in which UNL may invest may not track changes in the price of the Benchmark Futures Contracts. Other Natural Gas-Related Investments, including over-the-counter swap contracts, may also expose UNL to increased counterparty credit risk and may be less liquid and more difficult to value than Futures Contracts. UNL and the Related Public Funds ameliorate the potential credit, liquidity and valuation risks by fully collateralizing any over-the-counter swap contracts or other investments. In making compensation decisions, the Board considers whether a compensation arrangement would expose UNL or the Related Public Funds to additional risks and whether the risks posed by such arrangement are consistent with the best interests of UNL’s investors.

Other Information

In addition to the certifications of the Chief Executive Officer and Chief Financial Officer of USCF filed or furnished with this annual report on Form 10-K regarding the quality of UNL’s public disclosure, UNL will submit, within 30 days after filing this annual report on Form 10-K, to the NYSE Arca a certification of the Chief Executive Officer of USCF certifying that he is not aware of any violation by UNL of NYSE Arca corporate governance listing standards.

Item 11. | Executive Compensation.

Compensation to USCF and Other Compensation

UNL does not directly compensate any of the executive officers noted above. The executive officers noted above are compensated by USCF for the work they perform on behalf of UNL and other entities controlled by USCF. UNL does not reimburse USCF for, nor does it set the amount or form of any portion of, the compensation paid to the executive officers by USCF. UNL pays fees to USCF pursuant to the LP Agreement under which it is obligated to pay USCF an annualized fee of 0.75% of its average daily total net assets.

Item 12. | Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters.

None of the directors or executive officers of USCF, nor the employees of UNL own any shares of UNL. In addition, UNL is not aware of any 5% holder of its shares.

Item 13. | Certain Relationships and Related Transactions, and Director Independence.

Certain Relationships and Related Transactions

UNL has and will continue to have certain relationships with USCF and its affiliates. However, there have been no direct financial transactions between UNL and the directors or officers of USCF that have not been disclosed herein. See “Item 11. Executive Compensation” and “Item 12. Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters.” Any transaction with a related person that must be disclosed in accordance with SEC Regulation S-K item 404(a), including financial transactions by UNL with directors or executive officers of USCF or holders of beneficial interests in USCF or UNL of more than 5%, will be subject to the provisions regarding “Resolutions of Conflicts of Interest; Standard of Care” as set forth in Section 7.7 of the LP Agreement and will be reviewed and approved by the audit committee of the Board of USCF.

Director Independence

In February 2015, the Board undertook a review of the independence of the directors of USCF and considered whether any director has a material relationship or other arrangement with USCF, UNL, or the Related Public Funds that could compromise his ability to exercise independent judgment in carrying out his responsibilities. As a result of this review, the Board determined that each of Messrs. Fobes, Ellis and Robinson is an “independent director,” as defined under the rules of NYSE Arca.

Audit fees consist of fees paid to Spicer Jeffries LLP for (i) the audit of UNL’s annual financial statements included in the annual report on Form 10-K, and review of financial statements included in the quarterly reports on Form 10-Q and certain of UNL’s current reports on Form 8-K; and (ii) services that are normally provided by the Independent Registered Public Accountants in connection with statutory and regulatory filings of registration statements.

Tax fees consist of fees paid to Spicer Jeffries LLP for professional services rendered in connection with tax compliance and partnership income tax return filings.

The audit committee has established policies and procedures which are intended to control the services provided by UNL’s independent auditors and to monitor their continuing independence. Under these policies and procedures, no audit or permitted non-audit services (including fees and terms thereof), except for the de minimis exceptions for non-audit services described in Section 10A(i)(1)(B) of the Exchange Act, may be undertaken by UNL’s independent auditors unless the engagement is specifically pre-approved by the audit committee. The audit committee may form and delegate authority to subcommittees consisting of one or more members when appropriate, including the authority to grant pre-approvals of audit and permitted non-audit services, provided that decisions of such subcommittee to grant pre-approvals must be presented to the full audit committee at its next scheduled meeting.
