UNITED STATES 12 MONTH OIL FUND, LP

Table of Contents

Part I

Item 1.  Business.

What is USL?

The United States 12 Month Oil Fund, LP (“USL”) is a Delaware limited partnership organized on June 27, 2007. USL maintains its main business office at 1999 Harrison Street, Suite 1530, Oakland, California 94612. USL 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 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 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. When calculating the daily movement of the average price of the 12 contracts, each contract month will be equally weighted. It is not the intent of USL to be operated in a fashion such that the per share NAV will equal, in dollar terms, the spot price of light, sweet crude oil or any particular futures contract based on light, sweet crude oil. It is not the intent of USL 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 Oil Futures Contracts (as defined below) and Other Oil-Related Investments (as defined below). USL’s shares began trading on December 6, 2007. USCF is the general partner of USL and is responsible for the management of USL.

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 of Wainwright’s shares. Wainwright is a holding company that that currently holds 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, as 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 Gasoline Fund, LP (“UGA”), the United States Diesel-Heating Oil Fund, LP (“UHN”), the United States Short Oil Fund, LP (“DNO”), the United States 12 Month Natural Gas Fund, LP (“UNL”), 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, UGA, UHN, DNO, UNL, 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 of its decision to liquidate USMI, terminate the offering and to terminate USMI’s obligations under the Exchange Act.

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 Area 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 Exchange Act. For more information about each of the Related Public Funds, investors in USL may call 1.800.920.0259 or visit www.unitedstatescommodityfunds.com or the SEC’s website at www.sec.gov.

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

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 USL’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 USL’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 USL. 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 USL Operate?

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

The net assets of USL consist primarily of investments in futures contracts for light, sweet crude oil, other types of crude oil, diesel-heating oil, gasoline, natural gas, and other petroleum-based fuels that are traded on the NYMEX, ICE Futures or other U.S. and foreign exchanges (collectively, “Oil Futures Contracts”) and, to a lesser extent, in order to comply with regulatory requirements or in view of market conditions, other oil-related investments such as cash-settled options on Oil Futures Contracts, forward contracts for oil, cleared swap contracts and non-exchange traded (“over-the-counter”) transactions that are based on the price of oil, other petroleum-based fuels, Oil Futures Contracts and indices based on the foregoing (collectively, “Other Oil-Related Investments”). Market conditions that USCF currently anticipates could cause USL to invest in Other Oil-Related Investments include those allowing USL to obtain greater liquidity or to execute transactions with more favorable pricing. For convenience and unless otherwise specified, Oil Futures Contracts and Other Oil-Related Investments collectively are referred to as “Oil Interests” in this annual report on Form 10-K. USL invests substantially the entire amount of its assets in Oil 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 USL are available on USL’s website at www.unitedstatescommodityfunds.com.

The investment objective of USL 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 light, sweet crude oil delivered to Cushing, Oklahoma, as measured by the daily changes in the average of the prices of 12 futures contracts for light, sweet crude oil traded on the 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 (the “Benchmark Oil Futures Contracts”), less USL’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 USL to be operated in a fashion such that its per share NAV will equal, in dollar terms, the spot price of light, sweet crude oil or any particular futures contract based on light, sweet crude oil. It is not the intent of USL 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. USL may invest in interests other than the Benchmark Oil Futures Contract to comply with accountability levels and position limits. For a detailed discussion of accountability levels and position limits, see “Item 1. Business – What are Oil Futures Contracts?” below in this annual report on Form 10-K.

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

The Benchmark Oil 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 “rolls” USL’s positions by closing, or selling, USL’s Oil Interests and reinvests the proceeds from closing these positions in new Oil Interests.

The anticipated dates on which the Benchmark Oil Futures Contracts are changed and USL’s Oil Interests are “rolled” will be posted on USL’s website at www.unitedstatescommodityfunds.com, and are subject to change without notice.

USL’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 Oil Interest, the specific types of Other Oil-Related Investments and characteristics of such Other Oil-Related Investments, the name and value of each Treasury security and cash equivalent, and the amount of cash held in USL’s portfolio. USL’s website is publicly accessible at no charge. USL’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 USL 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 the 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 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 USL. 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 Oil 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 USL 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 USL’s Investment Strategy?

In managing USL’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 Oil Interests, such as the Benchmark Oil 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 Oil Futures Contracts or Other Oil-Related Investments, USCF believes that the changes in percentage terms in USL’s per share NAV will continue to closely track the daily changes in percentage terms in the average of the prices of the price of the Benchmark Oil Futures Contract. 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 USL. Additionally, Oil Futures Contracts traded on the NYMEX have closely tracked the spot price of light, sweet crude oil. Based on these expected interrelationships, USCF believes that the changes in the price of USL’s shares traded on the NYSE Arca have closely tracked and will continue to closely track the changes in the spot price of light, sweet crude oil, on a percentage basis. For performance data relating to USL’s ability to track its benchmark, see “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations – Tracking USL’s Benchmark” in this annual report on Form 10-K.

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

USCF believes that market arbitrage opportunities will cause the daily changes in USL’s share price on the NYSE Arca to closely track the daily changes in USL’s per share NAV. USCF believes that the net effect of these two expected relationships and the relationships described above between USL’s per share NAV and the Benchmark Oil Futures Contracts, will be that the daily changes in the price of USL’s shares on the NYSE Arca will closely track, in percentage terms, the daily changes in the spot price of a barrel of light, sweet crude oil, less USL’s expenses. For performance data relating to USL’s ability to track its benchmark, see “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations – Tracking USL’s Benchmark” in this annual report on Form 10-K.

The specific Oil Futures Contracts purchased depend on various factors, including a judgment by USCF as to the appropriate diversification of USL’s investments in futures contracts with respect to the month of expiration, and the prevailing price volatility of particular contracts. In addition, USL may make use of a mixture of standard sized futures contracts as well as the smaller sized “mini” contracts. While USCF has made significant investments in NYMEX Oil Futures Contracts, for various reasons, including the ability to enter into the precise amount of exposure to the crude oil market, position limits or other regulatory requirements limiting USL’s holdings, and market conditions, it may invest in Futures Contracts traded on other exchanges or invest in Other Oil-Related Investments. To the extent that USL invests in Other Oil-Related Investments, it would prioritize investments in contracts and instruments that are economically equivalent to the Benchmark Oil 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 USL 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 Oil-Related Investments, a substantial portion of USL’s assets could be invested in accordance with such priority in Other Oil-Related Investments that are intended to replicate the return on the Futures Contracts. As USL’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 Oil-Related Investments at such higher levels. In addition, market conditions that USCF currently anticipates could cause USL to invest in Other Oil-Related Investments include those allowing USL 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 USL’s ability to invest in over-the-counter transactions and cleared swaps.

USCF may not be able to fully invest USL’s assets in the Futures Contracts having an aggregate notional amount exactly equal to USL’s NAV. For example, as standardized contracts, the Futures Contracts are for a specified amount of a particular commodity, and USL’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, USL may be better able to achieve the exact amount of exposure to changes in price of the Benchmark Oil Futures Contracts through the use of Other Oil-Related Investments, such as over-the-counter contracts that have better correlation with changes in price of the Benchmark Oil Futures Contracts.

USL anticipates that to the extent it invests in Futures Contracts other than contracts on light, sweet crude oil (such as futures contracts for diesel-heating oil, natural gas, and other petroleum-based fuels) and Other Oil-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 Oil-Related Investments against the current Benchmark Oil Futures Contracts.

USCF does not anticipate letting USL’s Oil Futures Contracts expire and taking delivery of the underlying commodity. Instead, USCF closes existing positions, e.g., when it changes the Benchmark Oil Futures Contracts or Other Oil-Related Investments or it otherwise determines it would be appropriate to do so and reinvests the proceeds in new Oil Futures Contracts or Other Oil-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 Crude Oil Market and the Petroleum-Based Fuel Market?

USL may purchase Oil Futures Contracts traded on the NYMEX that are based on light, sweet crude oil. It may also purchase contracts on other exchanges, including the ICE Futures and the Singapore Exchange. The NYMEX contracts provide for delivery of several grades of domestic and internationally traded foreign crudes, and, among other things, serves the diverse needs of the physical market. In Europe, Brent crude oil is the standard for futures contracts and is primarily traded on the ICE Futures Europe. Brent crude oil is the price reference for two-thirds of the world’s traded oil. The ICE Brent Futures is a deliverable contract with an option to cash settle which trades in units of 1,000 barrels (42,000 U.S. gallons). The ICE Futures also offers a West Texas Intermediate (“WTI”) crude oil futures contract which trades in units of 1,000 barrels. The WTI crude oil futures contract is cash settled against the prevailing market price for U.S. light sweet crude oil.

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.

Natural Gas. Natural gas accounts for almost a quarter of U.S. energy consumption. The natural gas futures contract listed and traded on the NYMEX trades in units of 10,000 million British thermal units 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. The price of natural gas has historically been volatile.

What are Oil Futures Contracts?

Futures Contracts are agreements between two parties. One party agrees to buy a commodity such as crude oil from the other party at a later date at a price and quantity agreed-upon when the contract is made. Oil Futures Contracts are traded on futures exchanges, including the NYMEX. For example, the Benchmark Oil Futures Contracts are traded on the NYMEX in units of 1,000 barrels. Oil 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 Oil 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 USL 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 Oil Futures Contracts and other Oil Futures Contracts traded on U.S.-based futures exchanges, such as the NYMEX, are not a fixed ceiling, but rather a threshold above which the NYMEX may exercise greater scrutiny and control over an investor’s positions. The current accountability level for investments for any one-month in the Benchmark Oil Futures Contracts is 10,000 net contracts. In addition, the NYMEX imposes an accountability level for all months of 20,000 net futures contracts for light, sweet crude oil. In addition, the ICE Futures maintains the same accountability levels, position limits and monitoring authority for its light, sweet crude oil contract as the NYMEX. If USL and the Related Public Funds exceed these accountability levels for investments in the futures contract for light, sweet crude oil, the NYMEX and ICE Futures will monitor such exposure and may ask for further information on their activities, including the total size of all positions, investment and trading strategy, and the extent of liquidity resources of USL and the Related Public Funds. If deemed necessary by the NYMEX and/or ICE Futures, USL could be ordered to reduce its aggregate position back to the accountability level. As of December 31, 2014, USL held 658 NYMEX Crude Oil Futures CL contracts. As of December 31, 2014, USL did not hold any Futures Contracts traded on the ICE Futures. For the year ended December 31, 2014, USL did not exceed accountability levels imposed by the NYMEX or ICE Futures.

Position limits differ from accountability levels in that they represent fixed limits on the maximum number of futures contracts that any person may hold and cannot allow such limits to be exceeded without express CFTC authority to do so. In addition to accountability levels and position limits that may apply at any time, the NYMEX and the ICE Futures impose position limits on contracts held in the last few days of trading in the near month contract to expire. It is unlikely that USL will run up against such position limits because USL’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, USL did not exceed any position limits imposed by the NYMEX and ICE Futures.

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, USL 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 USL, 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 USL to meet its investment objectives through limits that may inhibit USCF’s ability to sell additional Creation Baskets of USL. See “The Commodity Interest Markets – Regulation” in this annual report on Form 10-K for additional information.

Price Volatility. The price volatility of Oil 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. Oil Futures Contracts tend to be more volatile than stocks and bonds because price movements for crude oil are more currently and directly influenced by economic factors for which current data is available and are traded by crude oil futures traders throughout the day. Because USL invests a significant portion of its assets in Oil Futures Contracts, the assets of USL, and therefore the prices of USL’s shares, may be subject to greater volatility than traditional securities.

Marking-to-Market Futures Positions. Oil 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 USL’s futures positions have declined in value, USL may be required to post “variation margin” to cover this decline. Alternatively, if USL’s futures positions have increased in value, this increase will be credited to USL’s account.

Why Does USL Purchase and Sell Oil Futures Contracts?

USL’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 average price of the Benchmark Oil Futures Contracts, less USL’s expenses. USL invests primarily in Oil Futures Contracts. USL seeks to have its aggregate NAV approximate at all times the aggregate market value of the Oil Futures Contracts (or Other Oil-Related Investments) it holds.

In connection with investing in Oil Futures Contracts and Other Oil-Related Investments, USL holds Treasuries, cash and/or cash equivalents that serve as segregated assets supporting USL’s positions in Oil Futures Contracts and Other Oil-Related Investments. For example, the purchase of an Oil Futures Contract with a stated value of $10 million would not require USL 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 Oil Futures Contract, would be required. To secure its Oil Futures Contract obligations, USL would deposit the required margin with the FCM and would separately hold, through its Custodian, 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).

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

What are the Trading Policies of USL?

Liquidity

USL invests only in Oil Futures Contracts and Other Oil-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 in over-the-counter Other Oil-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 USL.

Spot Commodities

While the crude Oil Futures Contracts traded can be physically settled, USL does not intend to take or make physical delivery. USL may from time to time trade in Other Oil-Related Investments, including contracts based on the spot price of crude oil.

Leverage

USCF endeavors to have the value of USL’s Treasuries, cash and cash equivalents, whether held by USL or posted as margin or other collateral, at all times approximate the aggregate market value of its obligations under its Oil Futures Contracts and Other Oil-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 USL’s assets, it is not prohibited from doing so under the LP Agreement.

Borrowings

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

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

In addition to Oil Futures Contracts, there are also a number of listed options on the Oil 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 crude oil market. Consequently, USL may purchase options on crude Oil Futures Contracts on these exchanges in pursuing its investment objective.

In addition to the Oil Futures Contracts and options on the Oil Futures Contracts, there also exists an active non-exchange-traded market in derivatives tied to crude oil. 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 Oil Futures Contracts or exchange-traded options on the Oil 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. To reduce the credit risk that arises in connection with such contracts, USL 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.

USL may enter into certain transactions where an over-the-counter component is exchanged for a corresponding futures contract (“Exchange for Risk” or “EFR” transaction.) These EFR transactions may expose USL 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 EFR transaction will exist only on the day of execution.

USL 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 Oil Futures Contract. USL 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, USL limited its derivatives activities to Oil Futures Contracts and EFR transactions.

Pyramiding

USL 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 USL, BBH&Co. may hold USL’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 USL, BBH&Co. performs certain administrative and accounting services for USL and prepares certain SEC, NFA and CFTC reports on behalf of USL. 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.

USL 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 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 USL’s FCM, effective October 10, 2013. Prior to October 10, 2013, UBS Securities LLC (“UBS Securities”) was USL’s FCM. This agreement requires RBC Capital to provide services to USL, as of October 10, 2013, in connection with the purchase and sale of Oil Futures Contracts and Other Oil-Related Investments that may be purchased or sold by or through RBC Capital for USL’s account. For the period October 10, 2013 and after, USL pays RBC Capital commissions for executing and clearing trades on behalf of USL. Prior to October 10, 2013, USL paid UBS Securities commissions for executing and clearing trades on behalf of USL.

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 USL’s commencement of trading to October 10, 2013, UBS Securities was a futures clearing broker for USL. Effective October 10, 2013, RBC Capital became the futures clearing broker for USL. 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 its 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.

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 USL and as such will be paid commissions for executing and clearing trades on behalf of USL. Prior to October 10, 2013, UBS Securities acted only as clearing broker for USL and as such was paid commissions for executing and clearing trades on behalf of USL. 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 USL.

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

Currently, USCF does not employ commodity trading advisors for trading of USL 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 USL, it will choose each advisor based on arm’s-length negotiations and will consider the advisor’s experience, fees and reputation.

Fees of USL

Fees and Compensation Arrangements with USCF and Non-Affiliated Service Providers⁽¹⁾

Compensation to USCF

USL is contractually obligated to pay USCF a management fee based on 0.60% per annum on its average daily total net assets. Fees are calculated on a daily basis (accrued at 1/365 of the applicable percentage of total net assets on that day) and paid on a monthly basis. Total net assets are calculated by taking the current market value of USL’s total assets and subtracting any liabilities.

Fees and Compensation Arrangements between USL and Non-Affiliated Service Providers⁽³⁾

New York Mercantile Exchange Licensing Fee⁽⁵⁾ - 0.015% on all net assets

Expenses Paid or Accrued by USL from Inception through December 31, 2014 in dollar terms:

Expenses Paid or Accrued by USL from Inception through December 31, 2014 as a Percentage of Average Daily Net Assets:

Other Fees. USL also pays the fees and expenses associated with its tax accounting and reporting requirements. These fees were approximately $169,000 for the fiscal year ended December 31, 2014. In addition, USL is responsible for paying its portion of the directors’ and officers’ liability insurance for USL and the Related Public Funds and the fees and expenses of the independent directors who also serve as audit committee members of USL and the Related Public Funds organized as limited partnerships and, as of July 8, 2011, those Related Public Funds organized as a series of a Delaware statutory trust. USL 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 USL and the Related Public Funds. USL’s portion of such fees and expenses for the year ended December 31, 2014 was $15,649.

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 USL 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

USL’s per share NAV is calculated by:

The Administrator calculates the per share NAV of USL 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 Oil Futures Contracts traded on the NYMEX, but calculates or determines the value of all other USL investments (including Oil Futures Contracts not traded on the NYMEX, Other Oil-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., USL 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 USL 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.

In addition, in order to provide updated information relating to USL 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 USL as a base and updating that value throughout the trading day to reflect changes in the most recently reported trade price for the active light, sweet Oil Futures Contracts on the NYMEX. The prices reported for those Oil 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 Oil Futures Contract, 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 USL’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 USL’s shares are traded on the NYSE Arca, but real-time NYMEX trading prices for Oil 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 Oil Futures Contracts from the NYMEX’s immediately preceding trading session. In addition, other Oil Futures Contracts, Other Oil-Related Investments and Treasuries held by USL 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.

The NYSE Arca disseminates the indicative fund value through the facilities of CTA/CQ High Speed Lines. In addition, the indicative fund value is published on the NYSE Arca’s website and is available through on-line information services such as Bloomberg and Reuters.

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 USL shares on the NYSE Arca. Investors and market professionals are able throughout the trading day to compare the market price of USL and the indicative fund value. If the market price of USL shares diverges significantly from the indicative fund value, market professionals will have an incentive to execute arbitrage trades. For example, if USL appears to be trading at a discount compared to the indicative fund value, a market professional could buy USL shares on the NYSE Arca and sell short Oil Futures Contracts. Such arbitrage trades can tighten the tracking between the market price of USL and the indicative fund value and thus can be beneficial to all market participants.

Creation and Redemption of Shares

USL 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 USL or the distribution by USL 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 USL. 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 USL, 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 May 1, 2015), the applicable transaction fee paid by Authorized Participants was $350 to USL for each order they place to create or redeem one or more baskets; prior to July 1, 2011, this fee was $1,000. Authorized Participants who make deposits with USL in exchange for baskets receive no fees, commissions or other form of compensation or inducement of any kind from either USL or USCF, and no such person will have any obligation or responsibility to USCF or USL 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 USL. During the year ended December 31, 2014, USL issued 5 Creation Baskets and redeemed 6 Redemption Baskets.

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

Delivery of Required Deposits

An Authorized Participant who places a purchase order is responsible for transferring to USL’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 USL 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. USL’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:

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 USL, as described below. Prior to the delivery of the redemption distribution for a redemption order, the Authorized Participant must also have wired to USL’s account at the Custodian the non-refundable transaction fee due for the redemption order. An Authorized Participant may not withdraw a redemption order.

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 USL’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 USL 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 USL’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 USL 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 USL (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 USL 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, USL’s DTC account has been credited with the baskets to be redeemed. If USL’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 USL 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 USL’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 USL’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 USL’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.

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 USL for its expenses in connection with the creation and redemption of baskets, an Authorized Participant is required to pay a transaction fee to USL per order to create or redeem baskets, regardless of the number of baskets in such order. From July 1, 2011 through December 31, 2013 (and continuing at least through May 1, 2015), the applicable transaction fee paid by Authorized Participants was $350 to USL for each order they place 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 USL 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, USL 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 USL or the distribution by USL 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 USL 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 Oil Futures Contracts market and the market for Other Oil-Related Investments. The prices of shares offered by Authorized Participants are expected to fall between USL’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 USL in exchange for baskets receive no fees, commissions or other form of compensation or inducement of any kind from either USL or USCF, and no such person has any obligation or responsibility to USCF or USL 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 Oil Futures Contracts market and the market for Other Oil-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 Oil Futures Contracts and Other Oil-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.

Investments

USCF causes USL to transfer the proceeds from the sale of Creation Baskets to the Custodian or other custodian for trading activities. USCF will invest USL’s assets in Oil Futures Contracts and Other Oil-Related Investments and investments in Treasuries, cash and/or cash equivalents. When USL purchases an Oil Futures Contract and certain exchange-traded Other Oil-Related Investments, USL 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 Oil Interests at maturity. This deposit is known as initial margin. Counterparties in transactions in over-the-counter Oil Interests will generally impose similar collateral requirements on USL. 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:

Ongoing margin and collateral payments will generally be required for both exchange-traded and over-the-counter Oil Interests based on changes in the value of the Oil Interests. Furthermore, ongoing collateral requirements with respect to over-the-counter Oil 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 an Oil Interest, and each party’s creditworthiness. In light of the differing requirements for initial payments under exchange-traded and over-the-counter Oil Interests and the fluctuating nature of ongoing margin and collateral payments, it is not possible to estimate what portion of USL’s assets will be posted as margin or collateral at any given time. The Treasuries, cash and cash equivalents held by USL will constitute reserves that will be available to meet ongoing margin and collateral requirements. All interest income will be used for USL’s benefit.

A FCM, counterparty, government agency or commodity exchange could increase margin or collateral requirements applicable to USL 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 USL’s posted as margin for Oil Futures Contracts are held in segregated accounts pursuant to the CEA and CFTC regulations.

If USL enters into a swap agreement, USL must post both collateral and independent amounts to its swap counterparty(ies). The amount of collateral USL posts changes according to the amounts owed by USL to its counterparty on a given swap transaction, while independent amounts are fixed amounts posted by USL 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 USL, as well as shares of each Related Public Fund, is registered under the Securities Act. USL 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 are regulated as described above, as well as by the self regulatory association, FINRA.

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 USL 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.

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 USL to a risk of default since the failure of a bank with which USL had entered into a forward contract would likely result in a default and thus possibly substantial losses to USL.

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 over-the-counter 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.

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, 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 USL 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 USL 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 USL) began on April 10, 2013. For a financial entity (including a commodity pool such as USL), regular reporting requirements for equity, foreign exchange and other commodity swaps (including swaps on oil) began on May 29, 2013 and reporting of all historical swaps for all asset classes 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 USL 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.

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, USL 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 USL’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.

USL’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.

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, USL 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 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 USL, 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 USL to meet its investment objectives through limits that may inhibit USCF’s ability to sell additional Creation Baskets of USL.

Based on its current understanding of the final position limit regulations, USCF does not anticipate significant negative impact on the ability of USL 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 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.

Brokerage firms, such as USL’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 USL 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, USL 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 over-the-counter 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 USL’s trading, USL (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 USL 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 Regulations Applicable to USL

On August 12, 2013, the CFTC issued final rules establishing compliance obligations for commodity pool operators (“CPOs”) of investment companies registered under the Investment Company Act of 1940, as amended (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 USL is not a registered investment company under the Investment Company Act, the Harmonization Rules amended certain CFTC disclosure rules to make the requirements for all CPOs to periodically update their disclosure documents consistent with those of the SEC. This change will decrease the burden to USL 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 USL and USCF, but any such further rule changes could result in additional operating efficiencies for USL and USCF.

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. USL 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 Oil Futures Contracts. It is unclear at this time what impact of money market reform would have on USL’s ability to hedge risk, however, the imposition of a floating NAV could cause USL 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 USL 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 USL’s financial statements and the related notes.

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

Investment Risk

The net asset value of USL’s shares relates directly to the value of the Benchmark Oil Futures Contracts and other assets held by USL and fluctuations in the prices of these assets could materially adversely affect an investment in USL’s shares.

The net assets of USL consist primarily of investments in Oil Futures Contracts and, to a lesser extent, in Other Oil-Related Investments. The NAV of USL’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 light, sweet crude oil in the marketplace. Crude oil prices depend on local, regional and global events or conditions that affect supply and demand for oil.

Economic conditions. The demand for crude oil 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 crude oil prices. Other factors that affect general economic conditions in the world or in a major region, such as changes in population growth rates, periods of civil unrest, government austerity programs, or currency exchange rate fluctuations, can also impact the demand for crude oil. Sovereign debt downgrades, defaults, inability to access debt markets due to credit or legal constraints, liquidity crises, the breakup or restructuring of fiscal, monetary, or political systems such as the European Union, and other events or conditions that impair the functioning of financial markets and institutions also may adversely impact the demand for crude oil.

Other demand-related factors. Other factors that may affect the demand for crude oil and therefore its price, include technological improvements in energy efficiency; seasonal weather patterns, which affect the demand for crude oil associated with heating and cooling; increased competitiveness of alternative energy sources that have so far generally not been competitive with oil 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. Crude oil prices also vary depending on a number of factors affecting supply. For example, increased supply from the development of new oil supply sources and technologies to enhance recovery from existing sources tends to reduce crude oil prices to the extent such supply increases are not offset by commensurate growth in demand. Similarly, increases in industry refining or petrochemical manufacturing capacity may impact the supply of crude oil. World oil supply levels can also be affected by factors that reduce available supplies, such as adherence by member countries to OPEC production quotas and the occurrence of wars, hostile actions, 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 petroleum industry to find, produce, and refine oil and to manufacture petrochemicals, which in turn may affect the supply of and demand for oil.

Other market factors. The supply of and demand for crude oil 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 crude oil will have an efficient hedge only if the price they pay for their shares closely correlates with the price of crude oil. Investing in USL’s shares for hedging purposes involves the following risks:

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

USL’s NAV per share will change throughout the day as fluctuations occur in the market value of USL’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 light, sweet crude oil and the Benchmark Oil Futures Contract 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 USL’s shares may also be influenced by non-concurrent trading hours between the NYSE Arca and the various futures exchanges on which crude oil 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 sweet, light crude oil trade 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 global light sweet crude 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 sweet, light crude oil 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 USL’s net asset value may not correlate with daily percentage changes in the average of the prices of the Benchmark Oil Futures Contracts.

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

Daily percentage changes in the price of the Benchmark Oil Futures Contract may not correlate with daily percentage changes in the spot price of light, sweet crude oil.

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

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

The design of USL’s Benchmark Oil Futures Contracts consists of the near month contract to expire and the 11 following months, which are changed to the next month contract to expire and the 11 following months during one day each month. In the event of a crude oil 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 crude oil prices the value of the benchmark contract would tend to rise as it approaches expiration. Conversely, in the event of a crude oil 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 crude oil prices the value of the benchmark contract would tend to decline as it approaches expiration. When compared to total return of other price indices, such as the spot price of crude oil, the impact of backwardation and contango may cause the total return of USL’s per share NAV to vary significantly. Moreover, absent the impact of rising or falling oil prices, a prolonged period of contango could have a significant negative impact on USL’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 Oil Futures Contracts.

Designated contract markets, such as the NYMEX and ICE Futures, 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 USL is not) may hold, own or control. In addition to accountability levels and position limits, the NYMEX and ICE Futures 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.

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, USL may be limited with respect to the size of its investments in Oil Futures Contracts and Other Oil-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 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 USL, 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 USL to meet its investment objectives through limits that may inhibit USCF’s ability to sell additional Creation Baskets of USL.

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

USL has not limited the size of its offering and is committed to utilizing substantially all of its proceeds to purchase Oil Futures Contracts and Other Oil-Related Investments. If USL encounters accountability levels, position limits, or price fluctuation limits for Oil Futures Contracts on the NYMEX or ICE Futures, it may then, if permitted under applicable regulatory requirements, purchase Oil Futures Contracts on other exchanges that trade listed crude oil futures. In addition, if USL exceeds accountability levels on either the NYMEX or ICE Futures and is required by such exchanges to reduce its holdings, such reduction could potentially cause a tracking error between the price of USL’s shares and the average of the prices of the Benchmark Oil 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 USL’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 USL in making allocations for tax purposes and other factors, an investor’s allocable share of USL’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 USL 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 USL is in many respects uncertain. USL 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 USL’s allocation methods and require USL 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.

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

USL has received an opinion of counsel that, under current U.S. federal income tax laws, USL 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 USL’s annual gross income consists of “qualifying income” as defined in the Code, (ii) USL is organized and operated in accordance with its governing agreements and applicable law and (iii) USL does not elect to be taxed as a corporation for federal income tax purposes. Although USCF anticipates that USL has satisfied and will continue to satisfy the “qualifying income” requirement for all of its taxable years, that result cannot be assured. USL 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 USL 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, USL 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 USL as a corporation could materially reduce the after-tax return on an investment in shares and could substantially reduce the value of the shares.

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

USL 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 USL on its income. Instead, USL 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 USL.

This must be reported without regard to the amount (if any) of cash or property the shareholder receives as a distribution from USL during the taxable year. A shareholder, therefore, may be allocated income or gain by USL 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 USL 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 USL. 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 USL’s assets may be used to trade over-the-counter Oil Interests, 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 over-the-counter market, the current regulation of the over-the-counter contracts could expose USL in certain circumstances to significant losses in the event of trading abuses or financial failure by participants. As a result of such regulations, if USL 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 USL 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 over-the-counter market will be subject to much more extensive regulatory oversight.

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

USL 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 USL, in which case USL could suffer significant losses on these contracts.

If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, USL may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. USL 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 USL’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 crude oil production or exports, or another major export, can also make it difficult to liquidate a position. Because both Oil Futures Contracts and Other Oil-Related Investments may be illiquid, USL's Oil 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 USL 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 USL’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.

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

USL is not actively managed by conventional methods. Accordingly, if USL’s investments in Oil Interests are declining in value, USL 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 Oil Futures Contract. USCF will seek to cause the NAV of USL’s shares to track the Benchmark Oil Futures Contract during periods in which its price is flat or declining as well as when the price is rising.

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

USL’s shares are listed for trading on the NYSE Arca under the market symbol “USL.” 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 USL’s shares will continue to be met or will remain unchanged.

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

Although USL’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 USL and other funds.

USCF was formed to be the sponsor and manager of investment vehicles such as USL and has been managing such investment vehicles since April 2006. In managing and directing the day-to-day activities and affairs of USL, USCF relies heavily on Messrs. Nicholas D. Gerber, Howard Mah and John Hyland. On October 13, 2014, Mr. Hyland tendered his resignation to USCF effective May 1, 2015. In order to ensure an orderly transition, Mr. Hyland will remain as the Chief Investment Officer of USCF until May 1, 2015. On January 14, 2015, Mr. Mah tendered his resignation to USCF to be effective no later than July 15, 2015. Due to the resignations of Messrs. Hyland and Mah, Mr. Gerber has assumed a more active role in the day-to-day activities of USCF, USL and the Related Public Funds, as well as USCF Advisers LLC, USCF ETF Trust and its series the Stock Split Index Fund (USCF Advisers LLC, the USCF ETF Trust and its series the Stock Split Index Fund are affiliated companies of USCF and the Related Public Funds). On January 26, 2015, Mr. Gerber became the Chief Executive Officer, President and Secretary of Concierge Technologies, Inc. (“Concierge”), a company unaffiliated with USCF, other than through ownership by common control. Concierge is a publicly traded company whose stock is listed under the ticker symbol “CNGC.” None of the employees of USCF are employees of Concierge. The management of USCF intends to find replacements for Messrs. Hyland and Mah prior to their departure. However, there is a risk that if suitable replacements for Messrs. Hyland and Mah are not found prior to Mr. Hyland’s or Mr. Mah’s departure, such departures may have a material adverse effect on the management, operations and/or financial results of USL. The potential magnitude of such an adverse impact would be greater if Mr. Gerber’s increased responsibilities, as a result of his new position with Concierge made it more difficult for him to adequately assume directing the day-to-day activities of USCF, USL and the Related Public Funds particularly if suitable replacements for Messrs. Hyland and Mah are not found.

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 USL, including their regulatory obligations.

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

USL pays brokerage charges of approximately 0.01% of average total net assets based on brokerage fees of $3.50 per buy or sell, management fees of 0.60% 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 USL’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 USL’s activities are profitable. Accordingly, USL 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 USL.

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 USL 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 USL, please see “Item 1. Business – Regulation” in this annual report on Form 10-K.

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

Historically, Oil Futures Contracts and Other Oil-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, USL'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 USL’s shares. In such a case, USL may have no gains to offset losses from other investments, and investors may suffer losses on their investment in USL at the same time they incur losses with respect to other investments.

Variables such as drought, floods, weather, embargoes, tariffs and other political events may have a larger impact on crude oil prices and crude oil-linked instruments, including Oil Futures Contracts and Other Oil-Related Investments, than on traditional securities. These additional variables may create additional investment risks that subject USL'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 crude oil and prices of other financial assets, such as stocks and bonds, are negatively correlated. In the absence of negative correlation, USL cannot be expected to be automatically profitable during unfavorable periods for the stock market, or vice versa.

USL 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”).

USL 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 USL to credit and regulatory risk.

USL invests primarily in Oil Futures Contracts, a significant portion of which are traded on United States exchanges, including the NYMEX. However, a portion of USL’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 USL 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.

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

USL 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 USL. These persons are directors, officers or employees of other entities that may compete with USL for their services. They could have a conflict between their responsibilities to USL and to those other entities. As a result of these and other relationships, parties involved with USL have a financial incentive to act in a manner other than in the best interests of USL 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.

USL 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 USL trades using the clearing broker to be used by USL. 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 USL.

USL 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.

USL may terminate at any time, regardless of whether USL 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 USL could cause USL 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 USL. USL’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.

USL does not expect to make cash distributions.

USL has not previously made any cash distributions and intends to reinvest any realized gains in additional Oil 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, USL generally does not expect to distribute cash to limited partners. An investor should not invest in USL if the investor will need cash distributions from USL to pay taxes on its share of income and gains of USL, if any, or for any other reason. Nonetheless, although USL 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 Oil 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 USL’s net asset value.

If a substantial number of requests for redemption of Redemption Baskets are received by USL during a relatively short period of time, USL may not be able to satisfy the requests from USL’s assets not committed to trading. As a consequence, it could be necessary to liquidate positions in USL’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. USL 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 Oil Futures Contracts. It is unclear at this time what impact of money market reform would have on USL’s ability to hedge risk, however, the imposition of a floating NAV could cause USL to limit remaining assets solely in Treasuries and cash.

The failure or bankruptcy of a clearing broker or USL’s Custodian could result in a substantial loss of USL’s assets and could impair USL 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 USL, 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 USL’s assets posted with the clearing broker, although the majority of USL’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. USL 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.

In addition, to the extent USL’s clearing broker is required to post USL’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 USL’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 USL 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 USL’s trades.

In addition, the majority of USL’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 USL’s assets held by that Custodian, which, at any given time, would likely comprise a substantial portion of USL’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 USL’s intellectual property or technology, including the use of its business methods, trademarks and trading program software, without permission. USCF has a patent for USL’s business method and has registered its trademarks. USL does not currently have any proprietary software. However, if it obtains proprietary software in the future, any unauthorized use of USL’s proprietary software and other technology could also adversely affect its competitive advantage. USL 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 USL, or require it to change its proprietary software and other technology or enter into royalty or licensing agreements.

Introduction

USL, 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 USL 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 light, sweet crude oil delivered to Cushing, Oklahoma, as measured by the daily changes, in percentage terms, in the average of the prices of 12 futures contracts for light, sweet crude oil traded on the NYMEX that is the near month contract to expire and the contracts for the following 11 months for a total of 12 consecutive months’ contracts, except when the near month contract is within two weeks of expiration, in which case it will be measured by the futures contract that is the next month contract to expire and the contracts for the following 11 consecutive months, (the “Benchmark Oil Futures Contracts”), less USL’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 USL to be operated in a fashion such that the per share NAV will equal, in dollar terms, the spot price of light, sweet crude oil or any particular futures contract based on light, sweet crude oil. It is not the intent of USL to be operated in a fashion such that its per share NAV will reflect the percentage change of the price of any particular futures contracts as measured over a time period greater than one day. USCF believes that it is not practical to manage the portfolio to achieve such an investment goal when investing in Oil Futures Contracts and Other Oil-Related Investments.

USL seeks to achieve its investment objective by investing in a combination of Oil Futures Contracts and Other Oil-Related Investments such that daily changes in its per share NAV, measured in percentage terms, will closely track the daily changes in the average of the prices of the Benchmark Oil Futures Contracts, also measured in percentage terms. USCF believes the daily changes in the average of the prices of the Benchmark Oil Futures Contracts have historically exhibited a close correlation with the daily changes in the spot price of light, sweet crude oil.

On any valuation day, the Benchmark Oil Futures Contracts are the near month futures contract for light, sweet crude oil traded on the NYMEX and the contracts for the following 11 months for a total of 12 consecutive months’ contracts unless the near month contract is within two weeks of expiration in which case the Benchmark Oil Futures Contracts are the next month contract for light, sweet crude oil traded on the NYMEX and the contracts for the following 11 consecutive months.

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 USL are discussed in “Item 1. Business” and “Item 1A. Risk Factors” in this annual report on Form 10-K.

Price Movements

Crude oil futures prices were volatile during the year ended December 31, 2014 and exhibited moderate daily swings along with a downward trend during the year. The average price of the Benchmark Oil Futures Contracts started the year at $95.79 per barrel. Average prices hit a peak on June 25, 2014 at $101.74 per barrel. The low of the year was on December 18, 2014, when prices reached $56.32 per barrel. The year ended with the average price of the Benchmark Oil Futures Contracts at $56.57 per barrel, down approximately 40.94% over the year. USL’s per share NAV started the year at $42.83 and ended the year at $26.59 on December 31, 2014, a decrease of approximately 37.92% over the year. USL’s per share NAV reached its high for the year on June 25, 2014 at $47.47 and reached its low for the year on December 18, 2014 at $26.48. The average Benchmark Oil Futures Contracts prices listed above began with the February 2014 to January 2015 contracts and ended with the February 2015 to January 2016 contracts. The return of approximately 40.94% on the average price of the Benchmark Oil Futures Contracts listed above is a hypothetical return only and could not actually be achieved by an investor holding Oil Futures Contracts. An investment in Oil Futures Contracts would need to be rolled forward during the time period described in order to achieve such a result. Furthermore, the change in the nominal price of these differing crude Oil Futures Contracts, measured from the start of the year to the end of the year, does not represent the actual benchmark results that USL seeks to track, which are more fully described below, in the section titled “Tracking USL’s Benchmark.”

During the year ended December 31, 2014, crude oil began the year in a mild state of backwardation, meaning that the price of the near month crude Oil Futures Contract was greater than the price of the next month crude Oil Futures Contract, or contracts further away from expiration. Crude oil inventories, which reached historic levels in January 2009 and February 2009 and which appeared to be the primary cause of the steep level of contango, began to drop in March 2009 and continued to drop for the remainder of 2010 and the beginning of 2011. During the year ended December 31, 2013, crude oil inventories fluctuated, which contributed to the crude oil futures market alternating between contango and backwardation through the end of December 2013. During the year ended December 31, 2014, crude oil inventories, particularly those in Cushing, Oklahoma, began to build from present levels, which contributed to the crude oil futures market moving into contango through the end of December 2014. For a discussion of the impact of backwardation and contango on total returns, see “Term Structure of Crude Oil Prices and the Impact on Total Returns” below.

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

The per share NAV of USL’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 USL investments, including ICE Futures contracts or other futures contracts, as of the earlier of the close of the NYSE Arca or 4:00 p.m. New York time.

Results of Operations and the Crude Oil Market

Results of Operations. On December 6, 2007, USL listed its shares on the AMEX under the ticker symbol “USL.” On that day, USL established its initial offering price at $50.00 per share and issued 300,000 shares to the initial Authorized Participant, Merrill Lynch Professional Clearing Corp., in exchange for $15,000,000 in cash. As a result of the acquisition of the AMEX by NYSE Euronext, USL’s shares no longer trade on the AMEX and commenced trading on the NYSE Arca on November 25, 2008.

Since its initial offering of 11,000,000 shares, USL has registered one subsequent offering of its shares: 100,000,000 shares which were registered with the SEC on March 31, 2009. Shares offered by USL in the subsequent offerings were sold by it for cash at the shares’ per share NAV as described in the applicable prospectus. As of December 31, 2014, USL had issued 14,450,000 shares, 1,400,000 of which were outstanding. As of December 31, 2014, there were 96,550,000 shares registered but not yet issued.

More shares may have been issued by USL than are outstanding due to the redemption of shares. Unlike funds that are registered under the 1940 Act, shares that have been redeemed by USL cannot be resold by USL. As a result, USL 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, USL had the following Authorized Participants: Citadel Securities LLC, Citigroup Global Markets Inc., JP Morgan Securities Inc., Merrill Lynch Professional Clearing Corp., Morgan Stanley & Company, Inc., Newedge Group LLC, Nomura Securities International Inc., RBC Capital Markets LLC, SG Americas Securities LLC and Virtu Financial Capital Markets.

For the Year Ended December 31, 2014 Compared to the Year Ended December 31, 2013; and for the Year Ended December 31, 2013 Compared to the Year Ended December 31, 2012

Portfolio Expenses. USL’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 USL pays to USCF is calculated as a percentage of the total net assets of USL. 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, was a result of lower prices for crude oil and the related decrease in the value of the Oil Futures Contracts held and traded by USL; and the increase in the per share NAV for the year ended December 31, 2013, as compared to December 31, 2012, was a result of higher prices for crude oil and the related increase in the value of the Oil Futures Contracts held and traded by USL.

Average interest rates on short-term investments held by USL, including cash, cash equivalents and Treasuries, were similar during the year ended December 31, 2014, compared to the years ended December 31, 2013, and to the year ended 2012. As a result, the amount of income earned by USL as a percentage of average daily total net assets was similar during the year ended December 31, 2014, compared to years ended 2013 and 2012.

The decrease in total fees and expenses excluding management fees for the year ended December 31, 2014, compared to the years ended December 31, 2013 and 2012, was due to USL’s smaller size as measured by total net assets; and for the year ended December 31, 2013, compared to year ended December 31, 2012, the increase in USL’s total fees and expenses excluding management fees was due to USL’s larger size as measured by total net assets.

USL’s decrease in total commissions accrued to brokers for December 31, 2014, compared to the year ended December 31, 2013; and for the year ended December 31, 2013, compared to December 31, 2012, was a result of decreased brokerage fees due to a lower number of Oil Futures Contracts held and traded.

For the Three Months Ended December 31, 2014 Compared to the Three Months Ended December 31, 2013; and for the Three Months Ended December 31, 2013 Compared to the Three Months Ended December 31, 2012

Average interest rates on short-term investments held by USL, 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 to the three months ended 2012. As a result, the amount of income earned by USL as a percentage of average daily total net assets was similar during the year ended December 31, 2014, compared to years ended 2013 and 2012.

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 and 2012, was due to USL’s smaller size as measured by total net assets. The decrease in the total commissions accrued to brokers by USL for the three months ended December 31, 2014, compared to the three months ended December 31, 2013 and 2012, was a result of decreased brokerage fees due to a lower number of futures contracts being held and traded.

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

For the 30 valuation days ended December 31, 2014, the simple average daily change in the Benchmark Oil Futures Contracts was (0.954)%, while the simple average daily change in the per share NAV of USL over the same time period was (0.958)%. The average daily difference was (0.004)% (or (0.4) basis points, where 1 basis point equals 1/100 of 1%). As a percentage of the daily movement of the average price of the Benchmark Oil Futures Contracts, the average error in daily tracking by the per share NAV was (0.26)%, meaning that over this time period USL’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 USL’s per share NAV versus the daily movement of the Benchmark Oil 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 USL as compared to the monthly value of the Benchmark Oil Futures Contracts for the five years ended December 31, 2014.

Since the commencement of the offering of USL’s shares to the public on December 6, 2007 to December 31, 2014, the simple average daily change in the average price of the Benchmark Oil Futures Contracts was (0.02)%, while the simple average daily change in the per share NAV of USL over the same time period was (0.02)%. The average daily difference was 0.002% (or 0.2 basis points, where 1 basis point equals 1/100 of 1%). As a percentage of the daily movement of the average price of the Benchmark Oil Futures Contracts, the average error in daily tracking by the per share NAV was (0.74)%, meaning that over this time period USL’s tracking error was within the plus or minus 10% range established as its benchmark tracking goal.

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

For the year ended December 31, 2014, the actual total return of USL as measured by changes in its per share NAV was (37.92)%. This is based on an initial per share NAV of $42.83 on December 31, 2013 and an ending per share NAV as of December 31, 2014 of $26.59. During this time period, USL made no distributions to its shareholders. However, if USL’s daily changes in its per share NAV had instead exactly tracked the changes in the daily total return of the Benchmark Oil Futures Contracts, USL would have had an estimated per share NAV of $26.83 as of December 31, 2014, for a total return over the relevant time period of (37.36)%. The difference between the actual per share NAV total return of USL of (37.92)% and the expected total return based on the Benchmark Oil Futures Contracts of (37.36)% was an error over the time period of (0.56)%, which is to say that USL’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 USL pays, offset in part by the income that USL collects on its cash and cash equivalent holdings. During the year ended December 31, 2014, USL earned dividend and interest income of $15,837, 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, USL also collected $3,150 from its Authorized Participants for creating or redeeming baskets of shares. This income also contributed to USL’s actual total return. During the year ended December 31, 2014, USL incurred total expenses of $488,740. Income from dividends and interest and Authorized Participant collections net of expenses was $(469,753), which is equivalent to a weighted average net income rate of approximately (0.89)% for the year ended December 31, 2014.

By comparison, for the year ended December 31, 2013, the actual total return of USL as measured by changes in its per share NAV was 7.59%. This was based on an initial per share NAV of $39.81 on December 31, 2012 and an ending per share NAV as of December 31, 2013 of $42.83. During this time period, USL made no distributions to its shareholders. However, if USL’s daily changes in its per share NAV had instead exactly tracked the changes in the daily total return of the Benchmark Oil Futures Contracts, USL would have had an estimated per share NAV of $43.23 as of December 31, 2013, for a total return over the relevant time period of 8.59%. The difference between the actual per share NAV total return of USL of 7.59% and the expected total return based on the Benchmark Oil Futures Contracts of 8.59% was an error over the time period of (1.00)%, which is to say that USL’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 USL paid, offset in part by the income that USL collected on its cash and cash equivalent holdings. During the year ended December 31, 2013, USL earned dividend and interest income of $24,631, which is equivalent to a weighted average income rate of approximately 0.02% for such period. In addition, during the year ended December 31, 2013, USL also collected $8,050 from its Authorized Participants for creating or redeeming baskets of shares. This income also contributed to USL’s actual total return. During the year ended December 31, 2013, USL incurred total expenses of $842,737. Income from dividends and interest and Authorized Participant collections net of expenses was $(810,056), which is equivalent to a weighted average net income rate of approximately (0.95)% for the year ended December 31, 2013.

By comparison, for the year ended December 31, 2012, the actual total return of USL as measured by changes in its per share NAV was (8.40)%. This was based on an initial per share NAV of $43.46 on December 31, 2011 and an ending per share NAV as of December 31, 2012 of $39.81. During this time period, USL made no distributions to its shareholders. However, if USL’s daily changes in its per share NAV had instead exactly tracked the changes in the daily total return of the Benchmark Oil Futures Contracts, USL would have had an estimated per share NAV of $40.11 as of December 31, 2012, for a total return over the relevant time period of (7.71)%. The difference between the actual per share NAV total return of USL of (8.40)% and the expected total return based on the Benchmark Oil Futures Contracts of (7.71)% was an error over the time period of (0.69)%, which is to say that USL’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 USL paid, offset in part by the income that USL collected on its cash and cash equivalent holdings. During the year ended December 31, 2012, USL earned dividend and interest income of $38,380, 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, USL also collected $12,950 from its Authorized Participants for creating or redeeming baskets of shares. This income also contributed to USL’s actual total return. During the year ended December 31, 2012, USL incurred total expenses of $1,050,378. Income from dividends and interest and Authorized Participant collections net of expenses was $(999,048), which is equivalent to a weighted average net income rate of approximately (0.74)% for the year ended December 31, 2012.

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

First, USL may buy or sell its holdings in the then current Benchmark Oil Futures Contracts at a price other than the closing settlement price of that contract on the day during which USL executes the trade. In that case, USL may pay a price that is higher, or lower, than that of the Benchmark Oil Futures Contracts, which could cause the daily changes in the per share NAV of USL to either be too high or too low relative to the daily changes in the average price of the Benchmark Oil 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 Oil Futures Contracts at, or as close as possible to, the end of the day settlement price. However, it may not always be possible for USL 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 USL’s attempt to track the Benchmark Oil Futures Contracts over time.

Second, USL 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 USL to track slightly lower than daily changes in the price of the Benchmark Oil Futures Contract. At the same time, USL earns dividend and interest income on its cash, cash equivalents and Treasuries. USL 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 USL’s NAV. When this income exceeds the level of USL’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), USL will realize a net yield that will tend to cause daily changes in the per share NAV of USL to track slightly higher than daily changes in the average of the prices of the Benchmark Oil Futures Contracts. During the year ended December 31, 2014, USL earned, on an annualized basis, approximately 0.03% on its cash and cash equivalent holdings. It also incurred cash expenses on an annualized basis of (0.60)% for management fees, approximately (0.01)% in brokerage commission costs related to the purchase and sale of futures contracts and approximately (0.32)% for other expenses. The foregoing fees and expenses resulted in a net yield on an annualized basis of approximately (0.90)% and affected USL’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 Oil Futures Contracts. USCF anticipates that interest rates will continue to remain at historical lows and therefore, it is anticipated that fees and expenses paid by USL will continue to be higher than interest earned by USL. As such, USCF anticipates that USL will continue to underperform its benchmark until such time when interest earned at least equals or exceeds the fees and expenses paid by USL.

Third, USL may hold Other Oil-Related Investments in its portfolio that may fail to closely track the Benchmark Oil Futures Contracts’ total return movements. In that case, the error in tracking the Benchmark Oil Futures Contracts could result in daily changes in the per share NAV of USL that are either too high, or too low, relative to the daily changes in the average price of the Benchmark Oil Futures Contracts. During the year ended December 31, 2014, USL did not hold any Other Oil-Related Investments. If USL increases in size, and due to its obligations to comply with regulatory limits, USL may invest in Other Oil-Related Investments which may have the effect of increasing transaction related expenses and may result in increased tracking error.

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

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

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

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

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

*PAST PERFORMANCE IS NOT NECESSARILY INDICATIVE OF FUTURE RESULTS

An alternative way to view the same data is to subtract the dollar price of the average dollar price of the near 12 month contracts for light, sweet crude oil from the dollar price of the near month contract for light, sweet crude oil. If the resulting number is a positive number, then the near month price is higher than the average price of the near 12 months and the market could be described as being in backwardation. If the resulting number is a negative number, then the near month price is lower than the average price of the near 12 months and the market could be described as being in contango. The chart below shows the results from subtracting the average dollar price of the near 12 month contracts from the near month price for the 10 year period between December 31, 2004 and December 31, 2014. Investors will note that the crude oil 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 crude oil futures market is in backwardation, the near month only portfolio would tend to have a higher total return than the 12 month contract portfolio. Conversely, if the crude oil futures market was in contango, the portfolio containing 12 months’ worth of contracts would tend to outperform the near month only portfolio. The chart below shows the annual results of owning a portfolio consisting of the near month contract and a portfolio containing the near 12 months’ worth of contracts. In addition, the chart shows the annual change in the spot price of light, sweet crude oil. In this example, each month, the near month only portfolio would sell the near month contract at expiration and buy the next month out contract. The portfolio holding an equal number of the near 12 months’ worth of contracts would sell the near month contract at expiration and replace it with the contract that becomes the new twelfth month contract.

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

Historically, the crude oil futures markets have experienced periods of contango and backwardation, with backwardation being in place roughly as often as contango since oil futures for trading, started in 1982. Following the global financial crisis in the fourth quarter of 2008, the crude oil market moved into contango and remained in contango for a period of several years. During parts of 2009, the level of contango was unusually steep as a combination of slack U.S. and global demand for crude oil and issues involving the physical transportation and storage of crude oil at Cushing, Oklahoma, the primary pricing point for oil traded in the U.S., led to unusually high inventories of crude oil. Since then, a combination of improved transportation and storage capacity, along with growing demand for crude oil globally, has moderated the inventory build-up and lead to reduced levels of contango by 2011. The crude oil futures market moved back and forth between contango and backwardation during the year ended December 31, 2014.

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 USL’s investment objective of having the daily percentage changes in its per share NAV track the daily percentage changes in the average of the prices of the Benchmark Oil Futures Contracts since the impact of backwardation and contango tend to equally impact the daily percentage changes in price of both USL’s shares and the Benchmark Oil Futures Contracts. It is impossible to predict with any degree of certainty whether backwardation or contango will occur in the future. It is likely that both conditions will occur during different periods.

Crude Oil Market. During the year ended December 31, 2014, crude oil prices were impacted by several factors. On the consumption side, demand growth remained moderate inside and outside the United States as global economic growth, including emerging economies such as China and India, showed signs of slowing economic growth. Europe in particular showed signs of weakness as the ongoing financial and banking crisis raised concerns during the first quarter of 2013. On the supply side, efforts to reduce production in recent years by OPEC to more closely match global consumption were partially successful. However, continuing concerns about the political standoff with Iran have left the market subject to bouts of heightened volatility as OPEC’s ability to replace Iranian oil currently subject to embargo is not unlimited. In addition, security issues in Libya, Egypt, Iraq, and Syria also contributed to heightened volatility. In recent years, oil production in the United States and Canada has increased. However, limits on oil transportation infrastructure, including pipelines, have made it more difficult for the increased production to move to the centers of refining, often leading to a build-up in crude oil inventory in areas of the United States, such as the U.S. Midwest, and Canada. The result is that crude oil prices in the U.S. Midwest, where the pricing point of the light, sweet crude oil contract is located, have tended to trade at a lower price than crude oil in other parts of the United States and lower than global crude oil benchmarks such as Brent crude oil. United States crude oil prices finished the year ended December 31, 2014 approximately 45.87% lower than at the beginning of the year, as the global economy continues to adjust to periods of slow recovery and economic growth. USCF believes that should the global economic situation cease to improve, or decline, there is a meaningful possibility that crude oil prices could further retreat from their current levels, while any military actions involving Iran would likely have the opposite effect.

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

For the ten year time period between 2004 and 2014, the table below compares the monthly movements of crude oil prices versus the monthly movements of the prices of several other energy commodities, such as natural gas, diesel-heating oil, and unleaded gasoline, as well as several major non-commodity investment asset classes, such as large cap U.S. equities, U.S. government bonds and global equities. It can be seen that over this particular time period, the movement of crude oil on a monthly basis was neither strongly correlated nor inversely correlated with the movements of large cap U.S. equities, U.S. government bonds and natural gas. However, movements in crude oil were strongly correlated to movements in global equities, unleaded gasoline and diesel-heating oil.

PAST PERFORMANCE IS NOT NECESSARILY INDICATIVE OF FUTURE RESULTS

The table below covers a more recent, but much shorter, range of dates than the above table. Over the one year period ended December 31, 2014, crude oil still showed neither strongly correlated nor inversely correlated movements with large cap U.S. equities, U.S. government bonds, global equities and natural gas. Movements in crude oil were still strongly correlated to the movements in unleaded gasoline and diesel-heating oil.

PAST PERFORMANCE IS NOT NECESSARILY INDICATIVE OF FUTURE RESULTS

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

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

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. USL’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 USL’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 USL for its Oil Futures Contracts are provided by its commodity broker who uses market prices when available, while over-the-counter contracts are valued based on the present value of estimated future cash flows that would be received from or paid to a third party in settlement of these derivative contracts prior to their delivery date and valued on a daily basis. In addition, USL estimates interest and dividend income on a daily basis using prevailing rates earned on its cash and cash equivalents. These estimates are adjusted to the actual amount received on a monthly basis and the difference, if any, is not considered material.

Liquidity and Capital Resources

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

USL currently generates cash primarily from: (i) the sale of Creation Baskets and (ii) income earned on Treasuries, cash and/or cash equivalents. USL has allocated substantially all of its net assets to trading in Oil Interests. USL invests in Oil Interests to the fullest extent possible without being leveraged or unable to satisfy its current or potential margin or collateral obligations with respect to its investments in Oil Futures Contracts and Other Oil-Related Investments. A significant portion of USL’s NAV is held in Treasuries, cash and cash equivalents that are used as margin and as collateral for its trading in Oil Interests. The balance of the assets is held in USL’s account at the Custodian and in Treasuries at the FCM. Income received from USL’s investments in money market funds and Treasuries is paid to USL. During the years ended December 31, 2014 and 2013, USL’s expenses exceeded the income USL earned and the cash earned from the sale of Creation Baskets and the redemption of Redemption Baskets. During the years ended December 31, 2014 and 2013, USL used other assets to pay expenses, which could cause a decrease in USL’s NAV over time. To the extent expenses exceed income USL’s NAV will be negatively impacted.

USL’s investments in Oil Interests may be subject to periods of illiquidity because of market conditions, regulatory considerations and other reasons. For example, most commodity exchanges limit the fluctuations in futures contracts prices during a single day by regulations referred to as “daily limits.” During a single day, no trades may be executed at prices beyond the daily limit. Once the price of a futures contract has increased or decreased by an amount equal to the daily limit, positions in the contracts can neither be taken nor liquidated unless the traders are willing to effect trades at or within the specified daily limit. Such market conditions could prevent USL from promptly liquidating its positions in Oil Futures Contracts. During the year ended December 31, 2014, USL did not purchase or liquidate any of its positions while daily limits were in effect; however, USL cannot predict whether such an event may occur in the future.

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

Market Risk

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

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

Credit Risk

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

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

If, in the future, USL purchases 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, USL held cash deposits and investments in Treasuries and money market funds in the amount of $53,250,024 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, USL 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 USL. While USL’s exposure under these indemnification provisions cannot be estimated, they are not expected to have a material impact on USL’s financial position.

European Sovereign Debt

USL 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, USL requires liquidity to redeem shares, which redemptions must be in blocks of 50,000 shares as of February 29, 2012 called “Redemption Baskets.” (Prior to February 29, 2012, the size of the Redemption Basket was 100,000 shares.) USL 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

USL’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 USL’s NAV, currently 0.60% of NAV on its average daily total net assets.

USCF agreed to pay the start-up costs associated with the formation of USL, 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 USL and its shares with the SEC, FINRA and NYSE Arca (formerly, AMEX), respectively. However, since USL’s initial offering of shares, offering costs incurred in connection with registering and listing additional shares of USL have been directly borne on an ongoing basis by USL, 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 USL’s financial statements and its SEC, NFA and CFTC reports. USCF and USL have also entered into a licensing agreement with the NYMEX pursuant to which USL and the Related Public Funds, other than BNO, USCI, CPER, USAG and USMI, pay a licensing fee to the NYMEX. USL also pays the fees and expenses associated with its tax accounting and reporting requirements.

In addition to USCF’s management fee, USL 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 USL’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. USL 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 USL’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 USL’s existence. Either party may terminate these agreements earlier for certain reasons described in the agreements.

As of December 31, 2014, USL’s portfolio consisted of 658 Crude Oil Futures CL Contracts traded on the NYMEX. As of December 31, 2014, USL did not hold any Oil Futures Contracts traded on the ICE Futures. For a list of USL’s current holdings, please see USL’s website at www.unitedstatescommodityfunds.com.

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

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

USL 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.

USL may enter into certain transactions where an over-the-counter component is exchanged for a corresponding futures contract. (“Exchange for Risk” or “EFR” transaction.)  These EFR transactions may expose USL 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 EFR transaction will exist only on the day of execution. 

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

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

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

To reduce the credit risk that arises in connection with such contracts, USL 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 USL 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 USL 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. USL 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 reporting period of this annual report on Form 10-K, USL limited its derivatives activities to Oil Futures Contracts and EFR transactions.

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

Auditors’ Report on Internal Control over Financial Reporting

To the Partners of

United States 12 Month Oil Fund, LP

We have audited the internal control over financial reporting of United States 12 Month Oil Fund, LP (the “Fund”) as of December 31, 2014, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. The Fund’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Annual Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Fund’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

An entity’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States of America. An entity’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the entity; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the entity are being made only in accordance with authorizations of management and directors of the entity; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the entity’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of the effectiveness to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, the Fund maintained, in all material respects, effective internal control over financial reporting as of December 31, 2014, based on the criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the financial statements as of and for the year ended December 31, 2014, of the Fund and our report dated March 16, 2015 expressed an unqualified opinion on those financial statements.

NOTE 1 - ORGANIZATION AND BUSINESS

The United States 12 Month Oil Fund, LP (“USL”) was organized as a limited partnership under the laws of the state of Delaware on June 27, 2007. USL is a commodity pool that issues limited partnership shares (“shares”) that may be purchased and sold on the NYSE Arca, Inc. (the “NYSE Arca”). Prior to November 25, 2008, USL’s shares traded on the American Stock Exchange (the “AMEX”). USL 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 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. When calculating the daily movement of the average price of the 12 contracts, each contract month will be equally weighted. It is not the intent of USL to be operated in a fashion such that the per share NAV will equal, in dollar terms, the spot price of light, sweet crude oil or any particular futures contract based on light, sweet crude oil. It is not the intent of USL to be operated in a fashion such that its per share NAV will reflect the percentage change of the price of any particular futures contracts as measured over a time period greater than one day. United States Commodity Funds LLC (“USCF”), the general partner of USL, believes that it is not practical to manage the portfolio to achieve such an investment goal when investing in Oil Futures Contracts (as defined below) and Other Oil-Related Investments (as defined below). USL accomplishes its objective through investments in futures contracts for light, sweet crude oil, and other types of crude oil, diesel-heating oil, gasoline, natural gas and other petroleum-based fuels that are traded on the NYMEX, ICE Futures or other U.S. and foreign exchanges (collectively, “Oil Futures Contracts”) and other oil-related investments such as cash-settled options on Oil Futures Contracts, forward contracts for oil, cleared swap contracts and over-the-counter transactions that are based on the price of crude oil, diesel-heating oil, gasoline, natural gas and other petroleum-based fuels, Oil Futures Contracts and indices based on the foregoing (collectively, “Other Oil-Related Investments”). As of December 31, 2014, USL held 658 Oil Futures Contracts for light, sweet crude oil traded on the NYMEX and did not hold any Oil Futures Contracts traded on the ICE Futures.

USL commenced investment operations on December 6, 2007 and has a fiscal year ending on December 31. USCF is responsible for the management of USL. 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 (“UNG”), 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, “UNG” on April 18, 2007, “UGA” on February 26, 2008 and “UHN” on April 9, 2008, respectively. As a result of the acquisition of the AMEX by NYSE Euronext, each of USO’s, UNG’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”), the United States 12 Month Natural Gas Fund, LP (“UNL”) and the United States Brent Oil Fund, LP (“BNO”), which listed their limited partnership shares on the NYSE Arca under the ticker symbols “DNO” on September 24, 2009, “UNL” on November 18, 2009 and “BNO” on June 2, 2010, respectively. USCF is also the sponsor of the United States Commodity Index Fund (“USCI”), the United States Copper Index Fund (“CPER”), the United States Agriculture Index Fund (“USAG”) and the United States Metals Index Fund (“USMI”), each a series of the United States Commodity Index Funds Trust (the “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. On January 30, 2015, USCF as the sponsor of 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.

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.”

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

From July 1, 2011 through December 31, 2014 (and continuing at least through May 1, 2015), the applicable transaction fee paid by Authorized Participants is $350 to USL 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 USL but rather at market prices quoted on such exchange.

In December 2007, USL initially registered 11,000,000 shares on Form S-1 with the SEC. On December 6, 2007, USL listed its shares on the AMEX under the ticker symbol “USL”. On that day, USL established its initial per share NAV by setting the price at $50.00 and issued 300,000 shares in exchange for $15,000,000. USL also commenced investment operations on December 6, 2007 by purchasing Oil Futures Contracts traded on the NYMEX based on light, sweet crude oil. As of December 31, 2014, USL had registered a total of 111,000,000 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. USL earns interest on its assets denominated in U.S. dollars on deposit with the FCM at the 90-day Treasury bill rate. In addition, USL 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

USL is not subject to federal income taxes; each partner reports his/her allocable share of income, gain, loss deductions or credits on his/her own income tax return.

In accordance with accounting principles generally accepted in the United States of America (“GAAP”), USL 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. USL files an income tax return in the U.S. federal jurisdiction, and may file income tax returns in various U.S. states. USL 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 USL recording a tax liability that reduces net assets. However, USL’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. USL 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. USL 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 USL’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 USL 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”)

USL’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. USL 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 USL. These costs include registration fees paid to regulatory agencies and all legal, accounting, printing and other expenses associated with such offerings. These costs are accounted for as a deferred charge and thereafter amortized to expense over twelve months on a straight-line basis or a shorter period if warranted.

Cash Equivalents

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

Reclassification

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

Use of Estimates

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

Ongoing Registration Fees and Other Offering Expenses

USL 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, USL incurred $1,350, $82,385 and $44,844, respectively, in registration fees and other offering expenses.

Directors’ Fees and Expenses

USL is responsible for paying its portion of the directors’ and officers’ liability insurance for USL and the Related Public Funds and the fees and expenses of the independent directors who also serve as audit committee members of USL and the Related Public Funds. USL 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 USL and the Related Public Funds. USL’s portion of such fees and expenses for the year ended December 31, 2014 was $15,649. These fees and expenses for the year ended December 31, 2013 were $555,456 for USL and the Related Public Funds. USL’s portion of such fees and expenses for the year ended December 31, 2013 was $19,340. For the year ended December 31, 2012, these fees and expenses were $540,586 for USL and the Related Public Funds. USL’s portion of such fees and expenses for the year ended December 31, 2012 was $25,332. USL is responsible for paying its portion of any payments that may become due to the independent directors pursuant to the deferred compensation agreements entered into between the independent directors, USCF and the Related Public Funds, except USCI, CPER, USAG and USMI.

Licensing Fees

USL 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, USL incurred $7,910, $12,774 and $20,192, respectively, under this arrangement.

Investor Tax Reporting Cost

The fees and expenses associated with USL’s audit expenses and tax accounting and reporting requirements are paid by USL. These costs were approximately $169,000 for the year ended December 31, 2014 and approximately $150,000 for each of the years ended December 31, 2013 and 2012.

Other Expenses and Fees

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

NOTE 4 - CONTRACTS AND AGREEMENTS

USL is party to a marketing agent agreement, dated as of November 13, 2007, as amended from time to time, with the Marketing Agent and USCF, whereby the Marketing Agent provides certain marketing services for USL as outlined in the agreement. The fee of the Marketing Agent, which is borne by USCF, is equal to 0.06% on USL’s assets up to $3 billion and 0.04% on USL’s assets in excess of $3 billion. In no event may the aggregate compensation paid to the Marketing Agent and any affiliate of USCF for distribution related services exceed 10% of the gross proceeds of USL’s offering.

The above fees do not include website construction and development, which are also borne by USCF.

USL is also party to a custodian agreement, dated October 5, 2007, as amended from time to time, with Brown Brothers Harriman & Co. (“BBH&Co.”) and USCF, whereby BBH&Co. holds investments on behalf of USL. USCF pays the fees of the custodian, which are determined by the parties from time to time. In addition, USL is party to an administrative agency agreement, dated October 5, 2007, as amended from time to time, with USCF and BBH&Co., whereby BBH&Co. acts as the administrative agent, transfer agent and registrar for USL. 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 USL 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, USL entered into a brokerage agreement with RBC Capital Markets, LLC (“RBC Capital” or “RBC”) to serve as USL’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 USL in connection with the purchase and sale of Oil Futures Contracts and Other Oil-Related Investments that may be purchased and sold by or through RBC Capital and/or UBS Securities for USL’s account. In accordance with each agreement, RBC Capital and UBS Securities charge USL commissions of approximately $7 to $15 per round-turn trade, including applicable exchange and NFA fees for Oil Futures Contracts and options on Oil Futures Contracts. Such fees include those incurred when purchasing Oil Futures Contracts and options on Oil Futures Contracts when USL issues shares as a result of a Creation Basket, as well as fees incurred when selling Oil Futures Contracts and options on Oil Futures Contracts when USL redeems shares as a result of a Redemption Basket. Such fees are also incurred when Oil Futures Contracts and options on Oil Futures Contracts are purchased or redeemed for the purpose of rebalancing the portfolio. USL also incurs commissions to brokers for the purchase and sale of Oil Futures Contracts, Other Oil-Related Investments or short-term obligations of the United States of two years or less (“Treasuries”).

The decrease in the total commissions accrued to brokers for the year ended December 31, 2014 as compared to the year ended December 31, 2013, was primarily a result of the decrease in USL’s size during the year ended December 31, 2014, as compared to the year ended December 31, 2013. The decrease in the total commissions accrued to brokers for the year ended December 31, 2013 as compared to the year ended December 31, 2012, was primarily a result of the decrease in USL’s average total net assets during the year ended December 31, 2013, as compared to the year ended December 31, 2012. As an annualized percentage of average total net assets, the figure for the year ended December 31, 2014 represents approximately 0.01% of average total net assets. By comparison, the figure for the year ended December 31, 2013 represented approximately 0.01% of average total net assets and the figure for the year ended December 31, 2012 represented approximately 0.02% 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.

USL and the NYMEX entered into a licensing agreement on April 10, 2006, as amended on October 20, 2011, whereby USL was granted a non-exclusive license to use certain of the NYMEX’s settlement prices and service marks. Under the licensing agreement, USL 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. USL expressly disclaims any association with the NYMEX or endorsement of USL 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

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

USL may enter into futures contracts, options on futures contracts and cleared swaps to gain exposure to changes in the value of an underlying commodity. A futures contract obligates the seller to deliver (and the purchaser to accept) the future delivery of a specified quantity and type of a commodity at a specified time and place. Some futures contracts may call for physical delivery of the asset, while others are settled in cash. The contractual obligations of a buyer or seller may generally be satisfied by taking or making physical delivery of the underlying commodity or by making an offsetting sale or purchase of an identical futures contract on the same or linked exchange before the designated date of delivery.

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

All of the futures contracts held by USL were exchange-traded 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 USL enters into non-exchange traded contracts (including Exchange for Risk or EFR transactions), it is subject to the credit risk associated with counterparty non-performance. The credit risk from counterparty non-performance associated with such instruments is the net unrealized gain, if any, on the transaction. USL 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, USL bears the risk of financial failure by the clearing broker.

USL’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 USL’s assets posted with that FCM; however, the majority of USL’s assets are held in Treasuries, cash and/or cash equivalents with USL’s custodian and would not be impacted by the insolvency of a FCM. The failure or insolvency of USL’s custodian, however, could result in a substantial loss of USL’s assets.

USCF invests a portion of USL’s cash in money market funds that seek to maintain a stable per share NAV. USL 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, USL held investments in money market funds in the amounts of $24,000,000 and $51,156,064, respectively. USL 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, USL held cash deposits and investments in Treasuries in the amounts of $29,250,024 and $11,776,288, respectively, with the custodian and futures commission merchant. Some or all of these amounts may be subject to loss should USL’s custodian and/or futures commission merchant cease operations.

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

USL’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, USL 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 USL 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.

The following summarized (unaudited) quarterly financial information presents the results of operations and other data for three-month periods ended March 31, June 30, September 30 and December 31, 2014 and 2013.

NOTE 8 - FAIR VALUE OF FINANCIAL INSTRUMENTS

USL 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 USL (observable inputs) and (2) USL’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 USL’s securities at December 31, 2014 using the fair value hierarchy:

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

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

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

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