What is the Trust and the Trust Series?

The United States Commodity Index Funds Trust (the “Trust”) is a Delaware statutory trust formed on December 21, 2009. The Trust is a series trust formed pursuant to the Delaware Statutory Trust Act and is organized into four separate series (each series, a “Trust Series” and collectively, the “Trust Series”). The Trust includes the United States Commodity Index Fund (“USCI”), a commodity pool formed on April 1, 2010 and first made available to the public on August 10, 2010, the United States Copper Index Fund (“CPER”), a commodity pool formed on November 26, 2010 and first made available to the public on November 15, 2011, the United States Agriculture Index Fund (“USAG”), a commodity pool formed on November 26, 2010 and first made available to the public on April 13, 2012 and the United States Metals Index Fund (“USMI”), a commodity pool formed on November 26, 2010 and first made available to the public on June 19, 2012. The Trust and Trust Series maintain their main business offices at 1999 Harrison Street, Suite 1530, Oakland, CA 94612. USCI, CPER, USAG and USMI each issues units (“units”) that may be purchased and sold on the NYSE Arca, Inc. (the “NYSE Arca”). The Trust and each Trust Series operate pursuant to the terms of the Trust’s Second Amended and Restated Declaration of Trust and Trust Agreement dated as of November 10, 2010, as amended from time to time, (the “Trust Agreement”), which grants full management control to their sponsor, United States Commodity Funds LLC (“USCF”).

USCI’s Investment Objective

USCI invests in futures contracts for commodities that are currently traded on the New York Mercantile Exchange (the “NYMEX”), ICE Futures (“ICE Futures”), Chicago Board of Trade (“CBOT”), Chicago Mercantile Exchange (“CME”), London Metal Exchange (“LME”), Commodity Exchange, Inc. (“COMEX”) or on other foreign exchanges (the NYMEX, ICE Futures, CBOT, CME, LME, Comex and other foreign exchanges, collectively, the “Futures Exchanges”) (such futures contracts, collectively, “Futures Contracts”) and, to a lesser extent, in order to comply with regulatory requirements or in view of market conditions, other commodity-based contracts and instruments such as cash-settled options on Futures Contracts, forward contracts relating to commodities, cleared swap contracts and other non exchange traded (“over-the-counter”) transactions that are based on the price of commodities and Futures Contracts (collectively, “Other Commodity-Related Investments”). Market conditions that USCF currently anticipates could cause USCI to invest in Other Commodity Related Investments would be those allowing USCI to obtain greater liquidity or to execute transactions with more favorable pricing. Futures Contracts and Other Commodity-Related Investments collectively are referred to as “Commodity Interests.”

The investment objective of USCI is for the daily changes in percentage terms of its units’ per unit net asset value (“NAV”) to reflect the daily changes in percentage terms of the SummerHaven Dynamic Commodity Index Total Return^SM (the “Commodity Index”), less USCI’s expenses. USCF does not intend to operate USCI in a fashion such that its per unit NAV will equal, in dollar terms, the spot prices of the commodities underlying the Benchmark Component Futures Contracts (as defined below) that comprise the Commodity Index or the prices of any particular group of Futures Contracts. USCI will not seek to achieve its stated investment objective over a period of time greater than one day. USCI believes that it is not practical to manage the portfolio to achieve such an investment goal when investing in Futures Contracts and Other Commodity-Related Investments. The Commodity Index is designed to reflect the performance of a diversified group of commodities. The Commodity Index is comprised of 14 Futures Contracts that are selected on a monthly basis from a list of 27 possible Futures Contracts. The Futures Contracts that at any given time make up the Commodity Index are referred to herein as “Benchmark Component Futures Contracts.” The Commodity Index is owned and maintained by SummerHaven Index Management, LLC (“SummerHaven Indexing”) and calculated and published by Bloomberg, L.P. (“Bloomberg”). USCI invests first in the current Benchmark Component Futures Contracts and other Futures Contracts intended to replicate the return on the current Benchmark Component Futures Contracts and, thereafter may hold Futures Contracts in a particular commodity other than one specified as the Benchmark Component Futures Contract, or may hold Other Commodity-Related Investments that are intended to replicate the return on the Benchmark Futures Contracts, but may fail to closely track the Commodity Index’s total return movements. If USCI increases in size, and due to its obligations to comply with regulatory limits or due to other market pricing or liquidity factors, USCI may invest in Futures Contract months other than the designated month specified as the Benchmark Component Futures Contract, or in Other Commodity-Related Investments, which may have the effect of increasing transaction related expenses and may result in increased tracking error.

USCI’s units began trading on August 10, 2010. As of December 31, 2012, USCI held 1,058 Futures Contracts on the NYMEX, 2,240 Futures Contracts on the ICE Futures, 3,405 Futures Contracts on the CBOT, 637 Futures Contracts on the CME, 5,701 Futures Contracts on the LME and did not hold any Futures Contracts on the COMEX.

CPER’s Investment Objective

The investment objective of CPER is for the daily changes in percentage terms of its units’ per unit NAV to reflect the daily changes in percentage terms of the SummerHaven Copper Index Total Return^SM (the “Copper Index”), less CPER’s expenses. USCF does not intend to operate CPER in a fashion such that its per unit NAV will equal, in dollar terms, the spot prices of the commodities underlying the Benchmark Component Copper Futures Contracts (as defined below) that comprise the Copper Index or the prices of any particular group of Futures Contracts. CPER will not seek to achieve a stated investment objective over a period of time greater than one day. USCF believes that it is not practical to manage the portfolio to achieve such an investment goal when investing in Futures Contracts and Other Copper-Related Investments (as defined below). The Copper Index is designed to reflect the performance of the investment returns from a portfolio of copper futures contracts. The Copper Index is owned and maintained by SummerHaven Indexing and calculated and published by the NYSE Arca. The Copper Index is comprised of either two or three Eligible Copper Futures Contracts that are selected on a monthly basis based on quantitative formulas relating to the prices of the Eligible Copper Futures Contracts developed by SummerHaven Indexing. The Eligible Copper Futures Contracts that at any given time make up the Copper Index are referred to herein as “Benchmark Component Copper Futures Contracts.”

CPER seeks to achieve its investment objective by investing to the fullest extent possible in the Benchmark Component Copper Futures Contracts. Then, if constrained by regulatory requirements or in view of market conditions, CPER will invest next in other Eligible Copper Futures Contracts, and finally to a lesser extent, in other exchange traded futures contracts that are economically identical or substantially similar to the Benchmark Component Copper Futures Contracts if one or more other Eligible Copper Futures Contracts is not available. When CPER has invested to the fullest extent possible in exchange-traded futures contracts, CPER may then invest in other contracts and instruments based on the Benchmark Component Copper Futures Contracts, other Eligible Copper Futures Contracts or copper, such as cash-settled options, forward contracts, cleared swap contracts and swap contracts other than cleared swap contracts. Other exchange-traded futures contracts that are economically identical or substantially similar to the Benchmark Component Copper Futures Contracts and other contracts and instruments based on the Benchmark Component Copper Futures Contracts, are collectively referred to collectively as “Other Copper-Related Investments,” and together with Benchmark Component Copper Futures Contracts and other Eligible Copper Futures Contracts, “Copper Interests.” CPER’s units began trading on November 15, 2011. As of December 31, 2012, CPER held 28 Futures Contracts on the COMEX.

USAG’s Investment Objective

The investment objective of USAG is for the daily changes in percentage terms of its units’ per unit NAV to reflect the daily changes in percentage terms of the SummerHaven Dynamic Agriculture Index Total Return^SM (the “Agriculture Index”), less USAG’s expenses. USCF does not intend to operate USAG in a fashion such that its per unit NAV will equal, in dollar terms, the spot prices of the commodities underlying the Benchmark Component Agriculture Futures Contracts (as defined below) that comprise the Agriculture Index or the prices of any particular group of Futures Contracts. USAG will not seek to achieve its stated investment objective over a period of time greater than one day. USCF believes that it is not practical to manage the portfolio to achieve such an investment goal when investing in Futures Contracts and Other Agriculture-Related Investments (as defined below). The Agriculture Index is designed to reflect the performance of a diversified group of agricultural commodities. The Agriculture Index is owned and maintained by SummerHaven Indexing and calculated and published by the NYSE Arca. Futures contracts for the agricultural commodities comprising the Agriculture Index are traded on ICE Future US, ICE Futures Canada, the CBOT, the Kansas City Board of Trade (“KCBT”) and the CME and are collectively referred to herein as “Eligible Agriculture Futures Contracts.” The Agriculture Index is comprised of 14 Eligible Agriculture Futures Contracts that are selected on a monthly basis based on quantitative formulas developed by SummerHaven Indexing. The Eligible Agriculture Futures Contracts that at any given time make up the Agriculture Index are referred to herein as “Benchmark Component Agriculture Futures Contracts.” The relative weighting of the Benchmark Component Agriculture Futures Contracts will change on a monthly basis, based on quantitative formulas relating to the prices of the Benchmark Component Agriculture Futures Contracts developed by SummerHaven Indexing.

USAG seeks to achieve its investment objective by investing to the fullest extent possible in the Benchmark Component Agriculture Futures Contracts. Then, if constrained by regulatory requirements or in view of market conditions, USAG will invest next in other Eligible Agriculture Futures Contracts based on the same agricultural commodity as the futures contracts subject to such regulatory constraints or market conditions, and finally, to a lesser extent, in other exchange traded futures contracts that are economically identical or substantially similar to the Benchmark Component Agriculture Futures Contracts if one or more other Eligible Agriculture Futures Contracts is not available. When USAG has invested to the fullest extent possible in exchange-traded futures contracts, USAG may then invest in other contracts and instruments based on the Benchmark Component Agriculture Futures Contracts, other Eligible Agriculture Futures Contracts or the agricultural commodities included in the Agriculture Index, such as cash-settled options, forward contracts, cleared swap contracts and swap contracts other than cleared swap contracts. Other exchange-traded futures contracts that are economically identical or substantially similar to the Benchmark Component Agriculture Futures Contracts and other contracts and instruments based on the Benchmark Component Agriculture Futures Contracts, as well as metals included in the Agriculture Index, are collectively referred to as “Other Agriculture-Related Investments,” and together with Benchmark Component Agriculture Futures Contracts and other Eligible Agriculture Futures Contracts, “Agriculture Interests.” USAG’s units began trading on April 13, 2012. As of December 31, 2012, USAG held 29 Futures Contracts on the ICE Futures, 9 Futures Contracts on the CME, 4 Futures Contracts on the KCBT and 30 Futures Contracts on the CBOT.

USMI’s Investment Objective

The investment objective of USMI is for the daily changes in percentage terms of its units’ per unit NAV to reflect the daily changes in percentage terms of the SummerHaven Metals Index Total Return^SM (the “Metals Index”), less USMI’s expenses. USCF does not intend to operate USMI in a fashion such that its per unit NAV will equal, in dollar terms, the spot prices of the commodities underlying the Benchmark Component Metals Futures Contracts (as defined below) that comprise the Metals Index or the prices of any particular group of Futures Contracts. USMI will not seek to achieve its stated investment objective over a period of time greater than one day. USCF believes that it is not practical to manage the portfolio to achieve such an investment goal when investing in Futures Contracts and Other Metals-Related Investments (as defined below). The Metals Index is owned and maintained by SummerHaven Indexing and calculated and published by the NYSE Arca. Futures contracts for the metals in the Metals Index that are traded on the NYMEX, the LME and COMEX are collectively referred to herein as “Eligible Metals Futures Contracts.” The Metals Index is comprised of 10 Eligible Metals Futures Contracts that are selected on a monthly basis based on quantitative formulas developed by SummerHaven Indexing. The Eligible Metals Futures Contracts that at any given time make up the Metals Index are referred to herein as “Benchmark Component Metals Futures Contracts.” The relative weighting of the Benchmark Component Metals Futures Contracts will change on a monthly basis, based on quantitative formulas relating to the prices of the Benchmark Component Metals Futures Contracts developed by SummerHaven Indexing.

USMI seeks to achieve its investment objective by investing to the fullest extent possible in the Benchmark Component Metals Futures Contracts. Then, if constrained by regulatory requirements or in view of market conditions, USMI will invest next in other Eligible Metals Futures Contracts, and finally to a lesser extent, in other exchange traded futures contracts that are economically identical or substantially similar to the Benchmark Component Metals Futures Contracts if one or more other Eligible Metals Futures Contracts is not available. When USMI has invested to the fullest extent possible in exchange-traded futures contracts, USMI may then invest in other contracts and instruments based on the Benchmark Component Metals Futures Contracts, other Eligible Metals Futures Contracts or the metals included in the Metals Index, such as cash-settled options, forward contracts, cleared swap contracts and swap contracts other than cleared swap contracts. Other exchange-traded futures contracts that are economically identical or substantially similar to the Benchmark Component Metals Futures Contracts and other contracts and instruments based on the Benchmark Component Metals Futures Contracts are collectively referred to as “Other Metals-Related Investments,” and together with Benchmark Component Metals Futures Contracts and other Eligible Metals Futures Contracts, “Metals Interests.” USMI’s units began trading on June 19, 2012. As of December 31, 2012, USMI held 2 Futures Contracts on the NYMEX, 1 Futures Contract on the CME, 70 Futures Contracts on the LME and 11 Futures Contracts on the COMEX.

Who is USCF?

USCF is a single member limited liability company that was formed in the state of Delaware on May 10, 2005. Prior to June 13, 2008, USCF was known as Victoria Bay Asset Management, LLC. It maintains its main business office at 1999 Harrison Street, Suite 1530, Oakland, CA 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 previously owned an insurance company organized under Bermuda law (which has been liquidated) and a registered investment adviser firm named Ameristock Corporation, which has been distributed to the Wainwright shareholders. 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.

USCF also serves as general partner of the United States Oil Fund, LP (“USOF”), the United States Natural Gas Fund, LP (“USNG”), the United States 12 Month Oil Fund, LP (“US12OF”), the United States Gasoline Fund, LP (“UGA”), the United States Diesel-Heating Oil Fund, LP (formerly, the United States Heating Oil Fund, LP) (“USDHO”), the United States Short Oil Fund, LP (“USSO”), the United States 12 Month Natural Gas Fund, LP (“US12NG”) and the United States Brent Oil Fund, LP (“USBO”). USNG, US12OF, UGA, USDHO, USSO, US12NG and USBO are actively operating funds and all are listed on the NYSE Arca. All funds listed previously are referred to collectively herein as the “Related Public Funds.” The Related Public Funds are subject to reporting requirements under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). For more information about each of the Related Public Funds, investors in the Trust Series may call 1.800.920.0259 or visit www.unitedstatescommodityfunds.com or the U.S. Securities and Exchange Commission’s (the “SEC”) website at www.sec.gov.

USCF has also filed registration statements to register units of the United States Sugar Fund (“USSF”), the United States Natural Gas Double Inverse Fund (“UNGD”), the United States Gasoil Fund (“USGO”) and the United States Asian Commodities Basket Fund (“UAC”), each a series of the United States Commodity Funds Trust I, and the US Golden Currency Fund (“HARD”), a series of the United States Currency Funds Trust. USSF, UNGD, USGO, UAC and HARD are currently not available to the public, as such funds are still in the process of review by various regulatory agencies which have regulatory authority over USCF and such funds. UAC had been declared effective by the regulatory agencies which have regulatory authority over USCF and UAC, but at the time of filing this annual report on Form 10-K, UAC had not been made available to the public.

USCF is required to evaluate the credit risk of each Trust Series to the futures commission merchant (“FCM”), oversee the purchase and sale of each Trust Series’ units by certain authorized purchasers (“Authorized Purchasers”), review daily positions and margin requirements of each Trust Series and manage each Trust Series’ investments. USCF also pays the fees of ALPS Distributors, Inc., which serves as the marketing agent for each Trust Series (the “Marketing Agent”), Brown Brothers Harriman & Co. (“BBH&Co.”), which serves as the administrator (the “Administrator”) and the custodian (the “Custodian”) for each Trust Series, and SummerHaven Investment Management, LLC (“SummerHaven”), which serves as the commodity trading advisor for USCI, CPER, USAG and USMI.

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. Through its Management Directors, USCF manages the day-to-day operations of each Trust Series. The Board has an audit committee which is made up of the three independent directors (Peter M. Robinson, Gordon L. Ellis and Malcolm R. Fobes III). 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 Each Trust Series Operate?

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

The investment objective of each Trust Series is for the daily changes in percentage terms of its per unit NAV to reflect the daily changes in percentage terms of the Applicable Index, less each Trust Series expenses. USCF does not intend to operate any Trust Series in a fashion such that its per unit NAV will equal, in dollar terms, the price of the Applicable Index or the price of any particular Applicable Benchmark Component Futures Contract. USCF believes that it is not practical to manage each Trust Series’ portfolio to achieve such an investment goal when investing in the Applicable Benchmark Component Futures Contracts and Other Related Investments.

USCI’s Investment Objective.  USCI seeks to achieve its investment objective by investing in a mix of Commodity Interests such that the daily changes in its per unit NAV will closely track the daily changes in the Commodity Index. USCI’s positions in Commodity Interests are rebalanced on a monthly basis in order to track the changing nature of the Commodity Index. The portfolio rebalancing takes place during the last four business days of the month (“Rebalancing Period”). At the end of each of the days in the Rebalancing Period, one fourth of the prior month portfolio positions are replaced by equally-weighted positions reflecting the particular Benchmark Component Futures Contracts determined on the selection date, which is the fifth business day before the end of the month (“USCI’s Selection Date”). At the end of the Rebalancing Period, the Commodity Index will have an equal-weight position of approximately 7.14% in each of the selected Benchmark Component Futures Contracts which will be reflected in the rebalanced portfolio. After fulfilling the collateral requirements with respect to its Commodity Interests, USCI invests the remainder of its proceeds from the sale of creation baskets in short-term obligations of the United States of two years or less (“Treasuries”) or cash equivalents, and/or merely holds such assets in cash (generally in interest-bearing accounts).

CPER’s Investment Objective.  CPER seeks to achieve its investment objective by investing to the fullest extent possible in the Benchmark Component Copper Futures Contracts. Then, if constrained by regulatory requirements or in view of market conditions, CPER will invest next in other Eligible Copper Futures Contracts, and finally to a lesser extent, in other exchange traded futures contracts that are economically identical or substantially similar to the Benchmark Component Copper Futures Contracts if one or more other Eligible Copper Futures Contracts is not available. When CPER has invested to the fullest extent possible in exchange-traded futures contracts, it may then invest in Other Copper-Related Investments. After fulfilling the collateral requirements with respect to its Copper Interests, CPER invests the remainder of its proceeds from the sale of creation baskets in Treasuries or cash equivalents, and/or merely holds such assets in cash (generally in interest-bearing accounts).

USAG’s Investment Objective.  USAG seeks to achieve its investment objective by investing to the fullest extent possible in the Benchmark Component Agriculture Futures Contracts. Then, if constrained by regulatory requirements or in view of market conditions, USAG will invest next in other Eligible Agriculture Futures Contracts, and finally to a lesser extent, in other exchange traded futures contracts that are economically identical or substantially similar to the Benchmark Component Agriculture Futures Contracts if one or more other Eligible Agriculture Futures Contracts is not available. When USAG has invested to the fullest extent possible in exchange-traded futures contracts, it may then invest in Other Agriculture-Related Investments. After fulfilling the collateral requirements with respect to its Agriculture Interests, USAG will invest the remainder of its proceeds from the sale of creation baskets in Treasuries or cash equivalents, and/or merely hold such assets in cash (generally in interest-bearing accounts).

USMI’s Investment Objective.  USMI seeks to achieve its investment objective by investing to the fullest extent possible in the Benchmark Component Metals Futures Contracts. Then, if constrained by regulatory requirements or in view of market conditions, USMI will invest next in other Eligible Metals Futures Contracts, and finally to a lesser extent, in other exchange-traded futures contracts that are economically identical or substantially similar to the Benchmark Component Metals Futures Contracts if one or more other Eligible Metals Futures Contracts is not available. When USMI has invested to the fullest extent possible in exchange-traded futures contracts, it may then invest in Other Metal-Related Investments. After fulfilling the collateral requirements with respect to its Metals Interests, USMI will invest the remainder of its proceeds from the sale of creation baskets in Treasuries or cash equivalents, and/or merely hold such assets in cash (generally in interest-bearing accounts).

The anticipated dates on which each Trust Series’ positions in Applicable Interests will be rebalanced on a monthly basis are posted on each Trust Series’ website and are subject to change without notice.

USCF employs a “neutral” investment strategy in order to track changes in the Applicable Index regardless of whether the Applicable Index goes up or goes down. Each Trust Series’ “neutral” investment strategy is designed to permit investors generally to purchase and sell each Trust Series’ units for the purpose of investing indirectly in the applicable commodities market in a cost-effective manner, and/or to permit participants in the applicable commodities or other industries to hedge the risk of losses in their applicable commodity-related transactions. Accordingly, depending on the investment objective of an individual investor, the risks generally associated with investing in the commodities market and/or the risks involved in hedging may exist. In addition, an investment in a Trust Series involves the risks that the changes in the price of the Trust Series’ units will not accurately track the changes in the Applicable Index, and that changes in the Applicable Index will not closely correlate with changes in the spot prices of the applicable commodities underlying the Applicable Benchmark Component Futures Contracts.

Each Trust Series’ investment objective is for the daily changes in percentage terms of its per unit NAV to reflect the daily changes in percentage terms of the Applicable Index, not to have the market price of its units match, dollar for dollar, changes in the price of the Applicable Index or the applicable commodities underlying the Applicable Benchmark Component Futures Contracts that make up the Applicable Index. Contango and backwardation may impact the total return on investment in units of a Trust Series relative to a hypothetical direct investment in the commodities underlying the Applicable Benchmark Component Futures Contracts that make up the Applicable Index and, in the future, it is likely that the relationship between the market prices of a Trust Series’ units and changes in the spot prices of the commodities underlying the Applicable Benchmark Component Futures Contracts that make up the Applicable Index could be impacted by contango and backwardation. It is important to note that this comparison ignores the potential costs associated with physically owning and storing commodities, which could be substantial. For a more in-depth discussion of the impact of contango and backwardation, see “Item 1A. Risk Factors — The price relationship between each Applicable Index at any point in time and the Futures Contracts that will became the Applicable Benchmark Component Futures Contracts on the next rebalancing date will vary and may impact both a Trust Series’ total return and the degree to which its total return tracks that of commodity price indices”, in this annual report on Form 10-K.

Furthermore, each Trust Series also purchases Treasuries and holds cash and/or cash equivalents to meet its current or potential margin or collateral requirements with respect to its investments in Applicable Interests and to hold cash not required to be used as margin or collateral. There is not expected to be any meaningful correlation between the performance of a Trust Series’ investments in Treasuries, cash or cash equivalents and the changes in the prices of commodities or Applicable Interests. While the level of interest earned on or the market price of these investments may in some respect correlate to changes in the prices of commodities, this correlation is not anticipated as part of the Trust Series’ efforts to meet its objective.

Each Trust Series’ total portfolio composition is disclosed each business day that the NYSE Arca is open for trading on the applicable Trust Series’ website. For a list of each of USCI’s, CPER’s, USAG’s and USMI’s current holdings, please see USCI’s website at www.unitedstatescommodityindexfund.com, CPER’s website at www.unitedstatescopperindexfund.com, USAG’s website at www.unitedstatesagricultureindexfund.com and USMI’s website at www.unitedstatesmetalsindexfund.com. The website disclosure of portfolio holdings for each Trust Series is made daily and includes, as applicable, the name and value of each Applicable Benchmark Component Futures Contract, the specific types and values of Other Related Investments and characteristics of such Other Related Investments, the name and value of each Treasury and cash equivalent, and the amount of cash held in each Trust Series, as applicable. Each Trust Series’ website is publicly accessible at no charge. Each Trust Series’ assets used for margin and collateral are held in segregated accounts pursuant to the Commodity Exchange Act (the “CEA”) and CFTC regulations.

The units issued by a Trust Series may only be purchased by Authorized Purchasers and, effective as of May 1, 2012, only in blocks of 50,000 units called Creation Baskets. The amount of the purchase payment for a Creation Basket is equal to the aggregate NAV of the units in the Creation Basket. Prior to May 1, 2012, each of USCI, CPER and USAG issued units to Authorized Purchasers by offering baskets consisting of 100,000 units through ALPS Distributors, Inc., as the marketing agent (the “Marketing Agent”). USMI was not available to the public until June 19, 2012, and from its inception of offering, issues units to certain Authorized Purchasers by offering baskets consisting of 50,000 units through the Marketing Agent. Similarly, only Authorized Purchasers may redeem units and only in blocks of 50,000 units called Redemption Baskets. The amount of the redemption proceeds for a Redemption Basket is equal to the aggregate NAV of units in the Redemption Basket. The purchase price for Creation Baskets and the redemption price for Redemption Baskets are the actual per unit NAV calculated at the end of the business day when a request for a purchase or redemption is received by the applicable Trust Series. The NYSE Arca publishes an approximate per unit NAV intra-day based on the prior day’s per unit NAV and the current price of the Applicable Benchmark Component Futures Contracts, but the price of Creation Baskets and Redemption Baskets is determined based on the actual per unit NAV calculated at the end of each trading day.

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

What is the Investment Strategy for each Trust Series?

In managing a Trust Series’ assets, USCF does not use a technical trading system that automatically issues buy and sell orders, other than to address monthly changes in the Applicable Benchmark Component Futures Contracts. Instead, each time one or more baskets are purchased or redeemed, USCF will purchase or sell Applicable Interests with an aggregate market value that approximates the amount of Treasuries and/or cash received or paid upon the purchase or redemption of the basket(s).

Each Trust Series endeavors to place trades in Applicable Interests and otherwise manage its investments so that “A” will be within plus/minus 10 percent of “B”, where:

• A is the average daily percentage change in such Trust Series’ per unit NAV for any period of 30 successive valuation days; i.e., any NYSE Arca trading day as of which the Trust Series calculates its per unit NAV; and

• B is the average daily percentage change in the price of the Applicable Index over the same period.

USCF believes that market arbitrage opportunities will cause the daily changes in each Trust Series’ unit price on the NYSE Arca to closely track the daily changes in such Trust Series’ per unit NAV. USCF believes that the net effect of this expected relationship and the expected relationship described above between a Trust Series’ per unit NAV and the Applicable Index will be that the daily changes in the price of a Trust Series’ units on the NYSE Arca will closely track the daily changes in the Applicable Index, less such Trust Series’ expenses. While the Applicable Index is composed of Applicable Benchmark Component Futures Contracts and is therefore a measure of the prices of the applicable commodities comprising the Applicable Index for future delivery, there is nonetheless expected to be a reasonable degree of correlation between the Applicable Index and the cash or spot prices of the commodities underlying the Applicable Benchmark Component Futures Contracts.

Commodity Interests.  The specific Commodity Interests purchased depend on various factors, including a judgment by USCF as to the appropriate diversification of USCI’s investments. While USCF has made significant investments in Benchmark Component Futures Contracts on the Futures Exchanges, for various reasons, including the ability to enter into the precise amount of exposure to the commodities market and position limits on Futures Contracts, it may also invest in economically equivalent Futures Contracts other than those that compose the Benchmark Component Futures Contracts and Other Commodity-Related Investments. To the extent that USCI invests in Other Related Investments, it would prioritize investments in contracts and instruments that are economically equivalent to the Benchmark Component 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. If USCI is required by law or regulation, or by one of its regulators, including a Futures Exchange, to reduce its position in one or more Benchmark Component Futures Contracts to the applicable position limit or to a specified accountability level, a substantial portion of USCI’s assets could be invested in Other Commodity-Related Investments that are intended to replicate the return on the Commodity Index or particular Benchmark Component Futures Contracts. As USCI’s assets reach higher levels, USCI 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 Other Commodity-Related Investments at such higher levels. In addition, market conditions that USCF currently anticipates could cause USCI to invest in Other Commodity-Related Investments include those allowing USCI 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 the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) on USCI’s ability to invest in OTC transactions and cleared swaps.

Copper Interests.  The specific Copper Interests purchased will depend on various factors, including a judgment by USCF as to the appropriate diversification of CPER’s investments. USCF anticipates, particularly while CPER has lesser amounts of assets, that it will make significant investments in Benchmark Component Copper Futures Contracts on the COMEX. In addition, for various reasons, including the ability to enter into the precise amount of exposure to the copper market or due to market conditions regarding liquidity or pricing of differing futures contracts, it may invest in other exchange-traded futures contracts that are economically identical or substantially similar to, the Benchmark Component Copper Futures Contracts. USCF further anticipates that as CPER grows larger, due to position limits on futures contracts or other regulatory requirements limiting CPER’s holdings, and market conditions, it may also invest in Other Copper-Related Investments. To the extent that CPER invests in Other Copper-Related Investments, it would prioritize investments in contracts and instruments that are economically equivalent to the Benchmark Component Copper Futures Contracts. In considering the use of Other Copper-Related Investments, USCF anticipates that it would first make use of swaps that clear through derivatives clearing organizations that satisfy CPER’s criteria if such swaps are available with respect to the Benchmark Component Copper Futures Contracts or the copper futures contracts included in the Copper Index. Then, and to a lesser extent, it would invest in other types of contracts, instruments and swaps, including uncleared swaps in the over-the-counter market. If CPER is required by law or regulation, or by one of its regulators, including the COMEX, to reduce its position in one or more Benchmark Component Copper 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 Copper-Related Investments, a substantial portion of CPER’s assets could be invested in accordance with such priority in Other Copper-Related Investments that are intended to replicate the return on the Copper Index or particular Benchmark Component Copper Futures Contracts. As CPER’s assets reach higher levels, CPER 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 Copper-Related Investments at such higher levels. In addition, market conditions that USCF currently anticipates could cause CPER to invest in Other Copper-Related Investments include those allowing CPER 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 the Dodd-Frank Act on CPER’s ability to invest in OTC transactions and cleared swaps.

Agriculture Interests.  The specific Agriculture Interests purchased will depend on various factors, including a judgment by USCF as to the appropriate diversification of USAG’s investments. USCF anticipates, particularly while USAG has lesser amounts of assets, that it will make significant investments in Benchmark Component Agriculture Futures Contracts on ICE Futures US, ICE Futures Canada, CBOT, KCBT and the CME. In addition, for various reasons, including the ability to enter into the precise amount of exposure to the agricultural commodities market or due to market conditions regarding liquidity or pricing of differing futures contracts, it may invest in other exchange-traded futures contracts that are economically identical or substantially similar to, the Benchmark Component Agriculture Futures Contracts. USCF further anticipates that as USAG grows larger, due to position limits on futures contracts or other regulatory requirements limiting USAG’s holdings, and market conditions, it may also invest in Other Agriculture-Related Investments. To the extent that USAG invests in Other Agriculture-Related Investments, it would prioritize investments in contracts and instruments that are economically equivalent to the Benchmark Component Agriculture Futures Contracts. In considering the use of Other Agriculture-Related Investments, USCF anticipates that it would first make use of swaps that clear through derivatives clearing organizations that satisfy USAG’s criteria if such swaps are available with respect to the Benchmark Component Agriculture Futures Contracts or the agricultural commodity futures contracts included in the Agriculture Index. Then, and to a lesser extent, it would invest in other types of contracts, instruments and swaps, including uncleared swaps in the over-the-counter market. If USAG is required by law or regulation, or by one of its regulators, including ICE Futures US, ICE Futures Canada, CBOT, KCBT or the CME, to reduce its position in one or more Benchmark Component Agriculture 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 Agriculture-Related Investments, a substantial portion of the USAG’s assets could be invested in accordance with such priority in Other Agriculture-Related Investments that are intended to replicate the return on the Agriculture Index or particular Benchmark Component Agriculture Futures Contracts. As the USAG’s assets reach higher levels, USAG 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 Agriculture-Related Investments at such higher levels. In addition, market conditions that USCF currently anticipates could cause USAG to invest in Other Agriculture-Related Investments include those allowing USAG to obtain greater liquidity or to execute transactions with more favorable pricing. See “Item 1. Regulation” in this Annual Report on Form 10-K for a discussion of the potential impact of the Dodd-Frank Act on USAG’s ability to invest in OTC transactions and cleared swaps.

Metals Interests.  The specific Metals Interests purchased will depend on various factors, including a judgment by USCF as to the appropriate diversification of USMI’s investments. USCF anticipates, particularly while USMI has lesser amounts of assets, that it will make significant investments in Benchmark Component Metals Futures Contracts on the NYMEX, LME and COMEX. In addition, for various reasons, including the ability to enter into the precise amount of exposure to the metals market or due to market conditions regarding liquidity or pricing of differing futures contracts, it may invest in other exchange-traded futures contracts that are economically identical or substantially similar to, the Benchmark Component Metals Futures Contracts. USCF further anticipates that as USMI grows larger, due to position limits on futures contracts or other regulatory requirements limiting USMI’s holdings, and market conditions, it may also invest in Other Metals-Related Investments. To the extent that USMI invests in Other Metals-Related Investments, it would prioritize investments in contracts and instruments that are economically equivalent to the Benchmark Component Metals Futures Contracts. In considering the use of Other Metals-Related Investments, USCF anticipates that it would first make use of swaps that clear through derivatives clearing organizations that satisfy USMI’s criteria if such swaps are available with respect to the Benchmark Component Metals Futures Contracts or the copper futures contracts included in the Metals Index. Then, and to a lesser extent, it would invest in other types of contracts, instruments and swaps, including uncleared swaps in the over-the-counter market. If USMI is required by law or regulation, or by one of its regulators, including the NYMEX, LME and COMEX, to reduce its position in one or more Benchmark Component Metals 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 Metals-Related Investments, a substantial portion of USMI’s assets could be invested in accordance with such priority in Other Metals-Related Investments that are intended to replicate the return on the Metals Index or particular Benchmark Component Metals Futures Contracts. As USMI’s assets reach higher levels, USMI 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 Metals-Related Investments at such higher levels. In addition, market conditions that USCF currently anticipates could cause USMI to invest in Other Metals-Related Investments include those allowing USMI 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 the Dodd-Frank Act on USMI’s ability to invest in OTC transactions and cleared swaps.

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

Each Trust Series anticipates that, to the extent it invests in Applicable Benchmark Component Futures Contracts other than the Applicable Benchmark Component Futures Contracts and Other Related Investments that are not economically equivalent to the Applicable Benchmark Component Futures Contracts, it will enter into various non-exchange-traded derivative contracts to hedge the short-term price movements of such Applicable Benchmark Component Futures Contracts and Other Related Investments against the current Applicable Benchmark Component Futures Contracts.

USCF does not anticipate letting its Applicable Benchmark Component Futures Contracts expire and taking delivery of any commodities. Instead, USCF closes existing positions, e.g., in response to ongoing changes in the Applicable Index or if it otherwise determines it would be appropriate to do so and reinvests the proceeds in new Applicable Interests. Positions may also be closed out to meet orders for Redemption Baskets, in which case the proceeds from closing the positions will not be reinvested.

The Trust Agreement contains no restrictions on the ability of USCF to change the investment objective of any Trust Series. Notwithstanding this, USCF has no intention of changing the investment objective of any Trust Series or the manner in which it intends to achieve its investment objective. Should USCF seek to change the investment objective of a Trust Series, such change would be reflected in an amended prospectus and would provide advance notice to investors.

What are Futures Contracts?

Futures contracts are agreements between two parties. One party agrees to buy a commodity such as natural gas or copper from the other party at a later date at a price and quantity agreed-upon when the contract is made. Generally, futures contracts traded on the NYMEX and the COMEX 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. Futures contracts may also be based on commodity indices, in that they call for a cash payment based on the change in the value of the specified index during a specified period. Additional risks of investing in futures contracts are included in “Item 1A. Risk Factors” in this annual report on Form 10-K.

Impact of Accountability Levels, Position Limits and Price Fluctuation Limits.  Futures contracts include typical and significant characteristics. Most significantly, the Commodity Futures Trading Commission (the “CFTC”) and U.S. designated contract markets such as the NYMEX, COMEX, CME, and CBOT 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 is not applicable to the Trust Series’ investments) 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 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, but does not limit the maximum daily price fluctuation, while some other non-U.S. futures exchanges have not adopted such limits.

The accountability levels for the commodities comprising an Applicable Index and other futures contracts traded on U.S.-based futures exchanges are not a fixed ceiling, but rather a threshold above which such exchanges may exercise greater scrutiny and control over an investor’s positions. As of December 31, 2012, USCI held 1,058 Futures Contracts on the NYMEX, 2,240 Futures Contracts on the ICE Futures, 3,405 Futures Contracts on the CBOT, 637 Futures Contracts on the CME, 5,701 Futures Contracts on the LME and did not hold any Futures Contracts on the COMEX. CPER held 28 Futures Contracts on the COMEX. USAG held 29 Futures Contracts on the ICE Futures, 9 Futures Contracts on the CME, 4 Futures Contracts on the KCBT and 30 Futures Contracts on the CBOT. USMI held 2 Futures Contracts on the NYMEX, 1 Futures Contract on the CME, 70 Futures Contracts on the LME and 11 Futures Contracts on the COMEX. For the year ended December 31, 2012, no Trust Series exceeded accountability levels imposed by the NYMEX, COMEX, CME, CBOT, KCBT 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 Futures Exchanges may impose position limits on contracts held in the last few days of trading in the near month contract to expire. It is unlikely that a Trust Series will run up against such position limits. A Trust Series does not typically hold the near month contract in its Applicable Benchmark Component Futures Contracts. In addition, each Trust Series’ investment strategy is to close out its positions during each Rebalancing Period in advance of the period right before expiration and purchase new contracts. As such, none of the Trust Series anticipates that position limits that apply to the last few days prior to a contract’s expiration will impact it. For the year ended December 31, 2012, no Trust Series exceeded position limits imposed by the NYMEX, COMEX, CME, CBOT, KCBT or ICE Futures.

In late 2011, the CFTC adopted rules that impose new position limits on Referenced Contracts (as defined below) involving 28 energy, metals and agricultural commodities (the “Position Limit Rules”). The Position Limit Rules were scheduled to become effective on October 12, 2012. However, on September 28, 2012, the United States District Court for the District of Columbia vacated these regulations on the basis of ambiguities in the provisions of the CEA (as modified by the Dodd-Frank Act) upon which the regulations were based. In its September 28, 2012 decision, the court remanded the Position Limit Rules to the CFTC with instructions to use its expertise and experience to resolve the ambiguities in the statute. On November 15, 2012, the CFTC indicated that it will move forward with an appeal of the District Court’s decision to vacate the Position Limit Rules. At this time, it is not possible to predict how the CFTC’s appeal could affect the Trust Series, but it may be substantial and adverse. Furthermore, until such time as the appeal is resolved or, if applicable revisions to the Position Limit Rules are proposed and adopted, the regulatory architecture in effect prior to the enactment of the Position Limit Rules will govern transactions in commodities and related derivatives (collectively, “Referenced Contracts”). Under that system, the CFTC enforces federal limits on speculation in agricultural products (e.g., corn, wheat and soy), while futures exchanges enforce accountability levels for agricultural and certain energy products (e.g., oil and natural gas). As a result, the Trust Series may be limited with respect to the size of its investments in any commodities subject to these limits. Finally, subject to certain narrow exceptions, the vacated Position Limit Rules would have required the aggregation, for purposes of the position limits, of all positions in the 28 Referenced Contracts held by a single entity and its affiliates, regardless of whether such position existed on U.S. futures exchanges, non-U.S. futures exchanges, in cleared swaps or in over-the-counter swaps. The CFTC is presently considering new aggregation rules, under a rulemaking proposal that is distinct from the Position Limit Rules. At this time, it is unclear how any modified aggregation rules may affect the Trust Series, but it may be substantial and adverse. By way of example, the aggregation rules in combination with any potential revised Position Limit Rules may negatively impact the ability of the Trust Series to meet its investment objectives through limits that may inhibit USCF’s ability to sell additional Creation Baskets of each Trust Series. See “Commodity Interest Markets – Regulation” in this annual report on Form 10-K for information regarding the Dodd-Frank Act.

10

Price Volatility.  The price volatility of futures contracts generally has been historically greater than that for traditional securities such as stocks and bonds. Price volatility often is greater day-to-day as opposed to intra-day. Because each Trust Series invests a significant portion of its assets in futures contracts, the assets of each Trust Series, and therefore the price of each Trust Series’ units, may be subject to greater volatility than traditional securities.

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

What is the Commodity Index?

The Commodity Index was developed based upon academic research by Yale University professors Gary B. Gorton and K. Geert Rouwenhorst, and Hitotsubashi University professor Fumio Hayashi. The Commodity Index is designed to reflect the performance of a fully margined or collateralized portfolio of 14 commodity futures contracts with equal weights, selected each month from a universe of 27 eligible commodity futures contracts. The Commodity Index is rules-based and rebalanced monthly based on observable price signals. In this context, the term “rules-based” is meant to indicate that the composition of the Commodity Index in any given month will be determined by quantitative formulas relating to the prices of the futures contracts that relate to the commodities that are eligible to be included in the Commodity Index. Such formulas are not subject to adjustment based on other factors. The overall return on the Commodity Index is generated by two components: (i) uncollateralized returns from the commodity futures contracts comprising the Commodity Index and (ii) a daily fixed income return reflecting the interest earned on a hypothetical 3-month U.S. Treasury Bill collateral portfolio, calculated using the weekly auction rate for the 3-Month U.S. Treasury Bills published by the U.S. Department of the Treasury. SummerHaven Indexing is the owner of the Commodity Index.

The Commodity Index is composed of physical non-financial commodity futures contracts with active and liquid markets traded upon futures exchanges in major industrialized countries. The futures contracts are denominated in U.S. dollars and weighted equally by notional amount. The Commodity Index currently reflects commodities in six commodity sectors: energy (e.g., crude oil, natural gas, heating oil, etc.), precious metals (e.g., gold, silver platinum), industrial metals (e.g., zinc, nickel, aluminum, copper, etc.), grains (e.g., wheat, corn, soybeans, etc.), softs (e.g., sugar, cotton, coffee, cocoa), and livestock (e.g., live cattle, lean hogs, feeder cattle).

Table 1 below lists the eligible commodities, the relevant futures exchange on which the futures contract is listed and quotation details. Table 2 lists the eligible futures contracts, their sector designation and maximum allowable tenor.

Prior to the end of each month, SummerHaven Indexing determines the composition of the Commodity Index and provides such information to Bloomberg. Values of the Commodity Index are computed by Bloomberg and disseminated approximately every fifteen (15) seconds from 8:00 a.m. to 5:00 p.m., New York City time, which also publishes a daily Commodity Index value at approximately 5:30 p.m., New York City time, under the index ticker symbol “SDCITR:IND”. Only settlement and last-sale prices are used in the Commodity Index’s calculation, bids and offers are not recognized — including limit-bid and limit-offer price quotes. Where no last-sale price exists, typically in the more deferred contract months, the previous days’ settlement price is used. This means that the underlying Commodity Index may lag its theoretical value. This tendency to lag is evident at the end of the day when the Commodity Index value is based on the settlement prices of the Benchmark Component Futures Contracts, and explains why the underlying Commodity Index often closes at or near the high or low for the day.

Composition of the Commodity Index

The composition of the Commodity Index on any given day, as determined and published by SummerHaven Indexing, is determinative of the benchmark for USCI. However, it is not possible to anticipate all possible circumstances and events that may occur with respect to the Commodity Index and the methodology for its composition, weighting and calculation. Accordingly, a number of subjective judgments must be made in connection with the operation of the Commodity Index that cannot be adequately reflected in this description of the Commodity Index. All questions of interpretation with respect to the application of the provisions of the Commodity Index methodology, including any determinations that need to be made in the event of a market emergency or other extraordinary circumstances, will be resolved by SummerHaven Indexing.

13

Contract Expirations

Because the Commodity Index is comprised of actively traded contracts with scheduled expirations, it can be calculated only by reference to the prices of contracts for specified expiration, delivery or settlement periods, referred to as contract expirations. The contract expirations included in the Commodity Index for each commodity during a given year are designated by SummerHaven Indexing, provided that each contract must be an active contract. An active contract for this purpose is a liquid, actively-traded contract expiration, as defined or identified by the relevant trading facility or, if no such definition or identification is provided by the relevant trading facility, as defined by standard custom and practice in the industry.

If a Futures Exchange ceases trading in all contract expirations relating to a particular Futures Contract, SummerHaven Indexing may designate a replacement contract on the commodity. The replacement contract must satisfy the eligibility criteria for inclusion in the Commodity Index. To the extent practicable, the replacement is effected during the next monthly review of the composition of the Commodity Index. If that timing is not practicable, SummerHaven Indexing determines the date of the replacement based on a number of factors, including the differences between the existing Futures Contract and the replacement Futures Contract with respect to contractual specifications and contract expirations.

If a contract is eliminated and there is no replacement contract, the underlying commodity will necessarily be dropped from the Commodity Index. The designation of a replacement contract, or the elimination of a commodity from the Commodity Index because of the absence of a replacement contract, could affect the value of the Commodity Index, either positively or negatively, depending on the price of the contract that is eliminated and the prices of the remaining contracts. It is impossible, however, to predict the effect of these changes, if they occur, on the value of the Commodity Index.

Commodity Selection

Fourteen of the 27 eligible Futures Contracts are selected for inclusion in the Commodity Index for the next month, subject to the constraint that each of the six commodity sectors is represented by at least one commodity. The methodology used to select the 14 Futures Contracts is based solely on quantitative data using observable futures prices and is not subject to human bias.

Monthly commodity selection is a two-step process based upon examination of the relevant futures prices for each commodity:

1) The annualized percentage price difference between the closest-to-expiration Futures Contract and the next closest-to-expiration Futures Contract is calculated for each of the 27 eligible Futures Contracts on USCI’s Selection Date. The seven commodities with the highest percentage price difference are selected.

2) For the remaining 20 eligible commodities, the percentage price change of each commodity over the previous year is calculated, as measured by the change in the price of the closest-to-expiration Futures Contract on the Selection Date from the price of the closest-to-expiration Futures Contract a year prior to USCI’s Selection Date. The seven commodities with the highest percentage price change are selected.

When evaluating the data from the second step, all six commodity sectors must be represented. If the selection of the seven additional commodities with the highest price change fails to meet the overall diversification requirement that all six commodity sectors are represented in the Commodity Index, the commodity with the highest price change among the commodities of the omitted sector(s) would be substituted for the commodity with the lowest price change among the seven additional commodities.

The 14 commodities selected are included in the Commodity Index for the next month on an equally-weighted basis. Due to the dynamic monthly commodity selection, the sector weights will vary from approximately 7% to 43% over time, depending on the price observations each month. USCI’s Selection Date for the Commodity Index is the fifth business day prior to the first business day of the next calendar month.

14

The following graph shows the sector weights of the commodities selected for inclusion in the Commodity Index as of December 31, 2012.

Contract Selection

For each commodity selected for inclusion into the Commodity Index for a particular month, the Commodity Index selects a specific Futures Contract with a tenor (i.e., contract month) among the eligible tenors (the range of contract months) based upon the relative prices of the Futures Contracts within the eligible range of contract months. The previous notwithstanding, the contract expiration is not changed for such month if a contract remains in the Commodity Index, as long as the contract does not expire or enter its notice period in the subsequent month.

Portfolio Construction

The portfolio rebalancing takes place during the Rebalancing Period. At the end of each of the days in the Rebalancing Period, one fourth of the prior month portfolio positions are replaced by an equally-weighted position in the commodity contracts determined on USCI’s Selection Date. At the end of the Rebalancing Period, the Commodity Index takes an equal-weight position of approximately 7.14% in each of the selected commodity contracts.

Commodity Index Total Return Calculation

The value of the Commodity Index on any business day is equal to the product of (i) the value of the Commodity Index on the immediately preceding business day multiplied by (ii) one plus the sum of the day’s returns for another version of the Commodity Index known as the SummerHaven Dynamic Commodity Index Excess Return (“SDCI ER”) (explained below) and one business day’s interest from hypothetical Treasuries. The value of the Commodity Index is calculated and published by Bloomberg.

Commodity Index Base Level

The Commodity Index was set to 100 on January 2, 1991.

15

SDCI ER Calculation

The total return of the SDCI ER reflects the percentage change of the market values of the underlying commodity futures. During the Rebalancing Period, the Commodity Index changes its contract holdings during a four day period. The value of the SDCI ER at the end of a business day “t” is equal to the SDCI ER value on day “t-1” multiplied by the sum of the daily percentage price changes of each commodity future factoring in each respective commodity future’s notional holding on day “t-1”.

Rebalancing Period

During the Rebalancing Period, existing positions are replaced by new positions based on the signals used for contract selection as outlined above. At the end of the first day of the Rebalancing Period, the signals are observed and on the second day a new portfolio is constructed that is equally weighted in terms of notional positions in the newly selected contracts.

2013 Holiday Schedule

The Commodity Index will not be computed on the following weekdays in 2013:

January	1
January	21
February	18

What is the Copper Index?

The Copper Index is a single-commodity index designed to be an investment benchmark for copper as an asset class. The Copper Index is composed of copper futures contracts on the COMEX exchange. The Copper Index attempts to maximize backwardation and minimize contango while utilizing contracts in liquid portions of the futures curve.

The Copper Index is rules-based and is rebalanced monthly based on observable price signals described below in the section “Contract Selection and Weighting.” In this context, the term “rules-based” is meant to indicate that the composition of the Copper Index in any given month will be determined by quantitative formulas relating to the prices of the futures contracts that are included in the Copper Index. Such formulas are not subject to adjustment based on other factors.

The overall return on the Copper Index is generated by two components: (i) uncollateralized returns from the Benchmark Component Copper Futures Contracts comprising the Copper Index, and (ii) a daily fixed income return reflecting the interest earned on hypothetical 3-month Treasuries, calculated using the weekly auction rate for 3-Month Treasuries published by the U.S. Department of the Treasury. SummerHaven Indexing is the owner of the Copper Index.

Prior to the end of each month, SummerHaven Indexing determines the composition of the Copper Index and provides such information to the NYSE Arca. Values of the Copper Index are computed by the NYSE Arca and disseminated approximately every fifteen (15) seconds from 8:00 a.m. to 5:00 p.m., New York City time, which also publishes a daily Copper Index value at approximately 5:30 p.m., New York City time, under the index ticker symbol “SCITR”. Only settlement and last-sale prices are used in the Copper Index’s calculation, bids and offers are not recognized — including limit-bid and limit-offer price quotes. Where no last-sale price exists, typically in the more deferred contract months, the previous days’ settlement price is used. This means that the underlying Copper Index may lag its theoretical value. This tendency to lag is evident at the end of the day when the Copper Index value is based on the settlement prices of the Benchmark Component Copper Futures Contracts, and explains why the underlying Copper Index often closes at or near the high or low for the day.

Composition of the Copper Index

The composition of the Copper Index on any given day, as determined and published by SummerHaven Indexing, is determinative of the benchmark for CPER. Neither the index methodology for the Copper Index nor any set of procedures, however, are capable of anticipating all possible circumstances and events that may occur with respect to the Copper Index and the methodology for its composition, weighting and calculation. Accordingly, a number of subjective judgments must be made in connection with the operation of the Copper Index that cannot be adequately reflected in this description of the Copper Index. All questions of interpretation with respect to the application of the provisions of the index methodology for the Copper Index, including any determinations that need to be made in the event of a market emergency or other extraordinary circumstances, will be resolved by SummerHaven Indexing.

Contract Expirations

Because the Copper Index is comprised of actively traded contracts with scheduled expirations, it can be calculated only by reference to the prices of contracts for specified expiration, delivery or settlement periods, referred to as contract expirations. The contract expirations included in the Copper Index for each commodity during a given year are designated by SummerHaven Indexing, provided that each contract must be an active contract. An active contract for this purpose is a liquid, actively-traded contract expiration, as defined or identified by the relevant trading facility or, if no such definition or identification is provided by the relevant trading facility, as defined by standard custom and practice in the industry.

If a futures exchange, such as the COMEX, ceases trading in all contract expirations relating to an Eligible Copper Futures Contract, SummerHaven Indexing may designate a replacement contract. The replacement contract must satisfy the eligibility criteria for inclusion in the Copper Index. To the extent practicable, the replacement will be effected during the next monthly review of the composition of the Copper Index. If that timing is not practicable, SummerHaven Indexing will determine the date of the replacement based on a number of factors, including the differences between the existing Benchmark Component Copper Futures Contract and the replacement contract with respect to contractual specifications and contract expirations.

17

The designation of a replacement contract could affect the value of the Copper Index, either positively or negatively, depending on the price of the contract that is eliminated and the prices of the replacement contract. It is impossible, however, to predict the effect of these changes, if they occur, on the value of the Copper Index.

Contract Selection and Weighting

Weights for each of the Benchmark Component Copper Futures Contracts are determined for the next month. The methodology used to calculate the Copper Index weighting is based solely on quantitative data using observable futures prices and is not subject to human bias.

The monthly weighting selection is a process based upon examination of the relevant futures prices for copper:

1) On CPER’s Selection Date (“CPER’s Selection Date”):

a) the copper futures curve is assessed to be in either backwardation or contango (as discussed below); and

b) the annualized percentage price difference between the Closest-to-Expiration Eligible Copper Futures Contract and each of the Next Four Eligible Copper Futures Contracts is calculated. For each month, the Closest-to-Expiration Eligible Copper Futures Contract and the Next Four Eligible Copper Futures Contracts are as follows:

Month

February

March

A futures curve in backwardation occurs when the price of the closest-to-expiration contract is greater than or equal to the price of the third closest-to-expiration contract. These contracts will have expirations that are approximately two months apart. A curve not in backwardation is defined as being in contango, which occurs when the price of the closest-to-expiration contract is less than the price of the third closest-to-expiration contract.

2a)  Backwardation: If the copper futures curve is in backwardation on the Selection Date, the Copper Index takes positions in the two Eligible Copper Futures Contracts with the highest annualized percentage price difference, each weighted at 50%.

A hypothetical example is included below, with the two selected Eligible Copper Futures Contracts shaded below (the selected commodities are ranked 1 and 2):

Copper Futures Contract	Expiration Date	ContractPrice
Nearest-to-maturity	November-10	374.70
Third nearest-to-maturity	January-11	365.20

Eligible Copper Futures Contracts	Price	Annualized   Percentage Price Difference	Ranking
January-11	365.20	10.47%	1
February-11	363.00	10.15%	4
March-11	359.70	10.36%	3
April-11	356.70	10.41%	2

18

2b)  Contango: If the copper futures curve is in contango, then the Copper Index takes positions in three Eligible Copper Futures Contracts, as follows: first, the Copper Index takes positions in the two Eligible Copper Futures Contracts with the highest annualized percentage price difference, each weighted at 25%; then, the Copper Index also takes a position in the closest-to-expiration December Eligible Future Contract that has expiration more distant than the fourth of the Next Four Eligible Copper Futures Contracts for the applicable month, which position is weighted at 50%.

A hypothetical example is included below, with the next two selected Eligible Copper Futures Contracts shaded below (the selected commodities are ranked 1 – 2):

Copper Futures Contract	Expiration                     Date	Contract Price
Nearest-to-maturity	November-10	374.00
Third nearest-to-maturity	January-11	375.70

Eligible Copper Futures Contracts	Price	Annualized     Percentage Price Difference	Ranking
January-11	375.70	(1.97)%	4
February-11	376.00	(1.78)%	3
March-11	376.30	(1.59)%	2
April-11	376.40	(1.37)%	1

Due to the dynamic monthly weighting calculation, the individual weights will vary-over time, depending on the price observations each month. CPER’s Selection Date for the Copper Index is the last business day of the calendar month.

The following graph shows the weights of the Benchmark Component Copper Futures Contracts selected for inclusion in the Copper Index as of December 31, 2012.

Portfolio Construction

The portfolio rebalancing takes place during the Rebalancing Period. At the end of each of the days in the Rebalancing Period one fourth of the prior month portfolio positions are replaced by the new weights for the Benchmark Component Copper Futures Contracts determined on CPER’s Selection Date.

Copper Index Total Return Calculation

The value of the Copper Index on any business day is equal to the product of (i) the value of the Copper Index on the immediately preceding business day multiplied by (ii) one plus the sum of the day’s returns for another version of the Copper Index known as the SummerHaven Dynamic Copper Index Excess Return (“SCI ER”) (explained below) and one business day’s interest from the hypothetical Treasury Bill portfolio. The value of the Copper Index will be calculated and published by the NYSE Arca.

Copper Index Base Level

The Copper Index was set to 100 on January 2, 1991.

SCI ER Calculation

The total return of the SCI ER reflects the percentage change of the market values of the underlying commodity futures. During the Rebalancing Period, the Copper Index changes its contract holdings and weightings during a four day period. The value of the SCI ER at the end of a business day “t” is equal to the SCI ER value on day “t -1” multiplied by the sum of the daily percentage price changes of each commodity future factoring in each respective commodity future’s notional holding on day “t -1”.

Rebalancing Period

The Copper Index is rebalanced during the first 4 business days of each calendar month, when existing positions are placed by new positions and weightings based on the signals used for contract selection on the last business day of the prior calendar month as outlined above.

2013 Holiday Schedule

The Copper Index will not be computed on the following weekdays in 2013:

January	1
January	21
February	18
March	29

The holiday schedule is subject to change. CPER will also not accept Creation Baskets or Redemption Baskets on these days.

What is the Agriculture Index?

The Agriculture Index is an agricultural sector index designed to broadly represent major agricultural commodities while overweighting the components that are assessed to be in a low inventory state and underweighting the components assessed to be in a high inventory state.

The Agriculture Index consists of fourteen agricultural markets: soybeans, corn, soft red winter wheat, hard red winter wheat, soybean oil, soybean meal, canola, sugar, cocoa, coffee, cotton, live cattle, feeder cattle and lean hogs. Each agricultural commodity is assigned a base weight based on an assessment of market liquidity and the commodity’s overall economic importance. Each commodity is U.S. dollar based, with the exception of canola, which is quoted in Canadian dollars and converted to U.S. dollars for the purpose of the Agriculture Index calculation.

20

Academic research by Professors Gorton, Rouwenhorst and Hayashi has shown that commodities in relatively low inventory states tend to have higher returns than commodities in relatively high inventory states. Furthermore, relative inventory comparisons can be estimated by the price-based signals momentum and basis. Momentum is the percentage price change in a commodity over the previous year. Basis is the annualized percentage difference between the nearest-to-maturity contract and the second nearest-to-maturity contract. Using these price-based signals, agricultural commodities determined to be in low inventory state will be weighted more heavily, and agricultural commodities in high inventory state will be weighted less heavily during any given month.

The Agriculture Index is rules-based and rebalanced monthly based on observable price signals described above. In this context, the term “rules-based” is meant to indicate that the composition of the Agriculture Index in any given month will be determined by quantitative formulas relating to the prices of the futures contracts that relate to the commodities that are included in the Agriculture Index. Such formulas are not subject to adjustment based on other factors.

The overall return on the Agriculture Index is generated by two components: (i) uncollateralized returns from the Benchmark Component Agriculture Futures Contracts comprising the Agriculture Index and (ii) a daily fixed income return reflecting the interest earned on a hypothetical 3-month U.S. Treasury Bill collateral portfolio, calculated using the weekly auction rate for the 3-Month U.S. Treasury Bills published by the U.S Department of the Treasury. SummerHaven Indexing is the owner of the Agriculture Index.

Prior to the end of each month, SummerHaven Indexing determines the composition of the Agriculture Index and provides such information to the NYSE Arca. Values of the Agriculture Index are computed by the NYSE Arca and disseminated approximately every fifteen (15) seconds from 8:00 a.m. to 5:00 p.m., New York City time, which also publishes a daily Agriculture Index value at approximately 5:30 p.m., New York City time, under the index ticker symbol “SDAITR”. Only settlement and last-sale prices are used in the Agriculture Index’s calculation, bids and offers are not recognized; including limit-bid and limit-offer price quotes. Where no last-sale price exists, typically in the more deferred contract months, the previous days’ settlement price is used. This means that the underlying Agriculture Index may lag its theoretical value. This tendency to lag is evident at the end of the day when the Agriculture Index value is based on the settlement prices of the Benchmark Component Agriculture Futures Contracts, and explains why the underlying Agriculture Index often closes at or near the high or low for the day.

Currency Conversion

Canola seed futures trade on the ICE Futures Canada and are denominated in Canadian dollars. Canola futures prices are divided by the USD/CAD foreign exchange spot price for purposes of index calculation and commodity weighting calculations. The USD/CAD price used for canola futures for the daily Agriculture Index value is the 3:00 p.m. EST USD/CAD price quoted by Bloomberg under currency ticker “USDCAD F150”.

Composition of the Agriculture Index

The composition of the Agriculture Index on any given day, as determined and published by SummerHaven Indexing, is determinative of the benchmark for USAG. Neither the Agriculture Index methodology nor any set of procedures, however, are capable of anticipating all possible circumstances and events that may occur with respect to the Agriculture Index and the methodology for its composition, weighting and calculation. Accordingly, a number of subjective judgments must be made in connection with the operation of the Agriculture Index that cannot be adequately reflected in this description of the Agriculture Index. All questions of interpretation with respect to the application of the provisions of the Agriculture Index methodology, including any determinations that need to be made in the event of a market emergency or other extraordinary circumstances, will be resolved by SummerHaven Indexing.

22

Contract Expirations

Because the Agriculture Index is comprised of actively traded contracts with scheduled expirations, it can be calculated only by reference to the prices of contracts for specified expiration, delivery or settlement periods, referred to as contract expirations. The contract expirations included in the Agriculture Index for each commodity during a given year are designated by SummerHaven Indexing, provided that each contract must be an active contract. An active contract for this purpose is a liquid, actively-traded contract expiration, as defined or identified by the relevant trading facility or, if no such definition or identification is provided by the relevant trading facility, as defined by standard custom and practice in the industry.

If a Futures Exchange ceases trading in all contract expirations relating to a particular Benchmark Component Agriculture Futures Contract, SummerHaven Indexing may designate a replacement contract on the particular agricultural commodity. The replacement contract must satisfy the eligibility criteria for inclusion in the Agriculture Index. To the extent practicable, the replacement will be effected during the next monthly review of the composition of the Agriculture Index. If that timing is not practicable, SummerHaven Indexing will determine the date of the replacement based on a number of factors, including the differences between the existing Benchmark Component Agriculture Futures Contract and the replacement contract with respect to contractual specifications and contract expirations.

If a Benchmark Component Agriculture Futures Contract is eliminated and there is no replacement contract, the underlying agricultural commodity will necessarily drop out of the Agriculture Index. The designation of a replacement contract, or the elimination of an agricultural commodity from the Agriculture Index because of the absence of a replacement contract, could affect the value of the Agriculture Index, either positively or negatively, depending on the price of the contract that is eliminated and the prices of the remaining contracts. It is impossible, however, to predict the effect of these changes, if they occur, on the value of the Agriculture Index.

Commodity Weighting

Each of the Benchmark Component Agriculture Futures Contracts will remain in the Agriculture Index from month to month. Weights for each of the Benchmark Component Agriculture Futures Contracts in the Agriculture Index are determined for the next month. The methodology used to calculate the Agriculture Index weighting is based solely on quantitative data using observable futures prices and is not subject to human bias.

The monthly weighting selection is a three-step process based upon examination of the relevant futures prices for each agricultural commodity:

1) The annualized percentage price difference between the closest-to-expiration Benchmark Component Agriculture Futures Contract and the next closest-to-expiration Benchmark Component Agriculture Futures Contract is calculated for each of the 14 eligible agricultural commodities on the fifth business day prior to the first business day of the next calendar month (the “USAG’s Selection Date”). The four agricultural commodities with the highest percentage price difference are selected.

2) For the remaining 10 eligible agricultural commodities, the percentage price change of each agricultural commodity over the previous year is calculated, as measured by the change in the price of the closest-to- expiration Benchmark Component Agriculture Futures Contract on the Selection Date from the price of the closest-to-expiration Benchmark Component Agriculture Futures Contract a year prior to the Selection Date. The three agricultural commodities with the highest percentage price change are selected.

3) For the seven commodities selected through basis (step 1) and momentum (step 2), each commodity weight is increased by 2% above its base weighting for the following month. For the remaining seven commodities not selected, each commodity weight is decreased by 2% below its base weighting for the following month.

Due to the dynamic monthly agricultural commodity weighting calculation, the individual agricultural commodity weights will vary over time, depending on the price observations each month. USAG’s Selection Date for the Agriculture Index is the fifth business day prior to the first business day of the next calendar month.

23

Contract Selection

For each agricultural commodity in the Agriculture Index, the index selects a specific Benchmark Component Agriculture Futures Contract with a tenor (i.e., contract month) among the eligible tenors (the range of contract months) based upon the relative prices of the Benchmark Component Agriculture Futures Contracts within the eligible range of contract months. The previous notwithstanding, the contract expiration is not changed for that month if a Benchmark Component Agriculture Futures Contract remains in the Agriculture Index, as long as the contract does not expire or enter its notice period in the subsequent month.

Portfolio Construction

The portfolio rebalancing takes place during the Rebalancing Period. At the end of each of the days in the last four business days of each month (the “Rebalancing Period”) one fourth of the prior month portfolio positions are replaced by the new commodity weights for the commodity contracts determined on USAG’s Selection Date.

Currency Conversion

Canola futures are denominated and quoted in Canadian dollars.

Agriculture Index Total Return Calculation

The value of the Agriculture Index on any business day is equal to the product of (i) the value of the Agriculture Index on the immediately preceding business day multiplied by (ii) one plus the sum of the day’s returns for another version of the Agriculture Index known as the SummerHaven Dynamic Agriculture Index Excess Return (“SDAI ER”) (explained below) and one business day’s interest from the hypothetical Treasury Bill portfolio. The value of the Agriculture will be calculated and published by the NYSE Arca.

Agriculture Index Base Level

The Agriculture Index was set to 100 on January 2, 1991.

24

SDAI ER Calculation

The total return of the SDAI ER reflects the percentage change of the market values of the underlying Benchmark Component Agriculture Futures Contracts. During the Rebalancing Period, the Agriculture Index changes its contract holdings and weightings during a four day period. The value of the SDAI ER at the end of a business day “t” is equal to the SDAI ER value on day “t -1” multiplied by the sum of the daily percentage price changes of each commodity future factoring in each respective commodity future’s notional holding on day “t -1”.

Rebalancing Period

During the Rebalancing Period, existing positions are replaced by new positions based on the signals used for contract selection as outlined above. At the end of the first day of the Rebalancing Period, the signals are observed and on the second day a new portfolio is constructed that is equally weighted in terms of notional positions in the newly selected contracts.

What is the Metals Index?

The Metals Index is a metal sector index designed to broadly represent industrial and precious metals while overweighting the components that are assessed to be in a low inventory state and underweighting the components assessed to be in a high inventory state.

The Metals Index consists of ten metals – six base metals and four precious metals. The base metals are aluminum, copper, zinc, nickel, tin and lead. The precious metals are gold, silver, platinum and palladium. Each metal is assigned a base weight based on an assessment of market liquidity and the metal’s overall economic importance.

Academic research by Professors Gorton, Rouwenhorst and Hayashi has shown that commodities in relatively low inventory states tend to have higher returns than commodities in relatively high inventory states. Furthermore, relative inventory comparisons can be estimated by the price-based signals momentum and basis.

Momentum is the percentage price change in a commodity over the previous year. Basis is the annualized percentage difference between the nearest-to-maturity contract and the second nearest-to-maturity contract. Using these price-based signals, metals determined to be in low inventory state will be weighted more heavily, and metals in high inventory state will be weighted less heavily during any given month.

The Metals Index is rules-based and is rebalanced monthly based on observable price signals described above. In this context, the term “rules-based” is meant to indicate that the composition of the Metals Index in any given month will be determined by quantitative formulas relating to the prices of the futures contracts that relate to the commodities that are included in the Metals Index. Such formulas are not subject to adjustment based on other factors.

The overall return on the Metals Index is generated by two components: (i) uncollateralized returns from the Benchmark Component Metals Futures Contracts comprising the Metals Index, and (ii) a daily fixed income return reflecting the interest earned on a hypothetical 3-month U.S. Treasury Bill collateral portfolio, calculated using the weekly auction rate for the 3-Month U.S. Treasury Bills published by the U.S Department of the Treasury. SummerHaven Indexing is the owner of the Metals Index.

Prior to the end of each month, SummerHaven Indexing determines the composition of the Metals Index and provides such information to the NYSE Arca. Values of the Metals Index are computed by the NYSE Arca and disseminated approximately every fifteen (15) seconds from 8:00 a.m. to 5:00 p.m., New York City time, which also publishes a daily Metals Index value at approximately 5:30 p.m., New York City time, under the index ticker symbol “SDMITR.” Only settlement and last-sale prices are used in the Metals Index’s calculation, bids and offers are not recognized; including limit-bid and limit-offer price quotes.

Composition of the Metals Index

The composition of the Metals Index on any given day, as determined and published by SummerHaven Indexing, is determinative of the benchmark for USMI. Neither the Metals Index methodology nor any set of procedures, however, are capable of anticipating all possible circumstances and events that may occur with respect to the Metals Index and the methodology for its composition, weighting and calculation. Accordingly, a number of subjective judgments must be made in connection with the operation of the Metals Index that cannot be adequately reflected in this description of the Metals Index. All questions of interpretation with respect to the application of the provisions of the Metals Index methodology, including any determinations that need to be made in the event of a market emergency or other extraordinary circumstances, will be resolved by SummerHaven Indexing.

26

Contract Expirations

Because the Metals Index is comprised of actively traded contracts with scheduled expirations, it can be calculated only by reference to the prices of contracts for specified expiration, delivery or settlement periods, referred to as contract expirations. The contract expirations included in the Metals Index for each commodity during a given year are designated by SummerHaven Indexing, provided that each contract must be an active contract. An active contract for this purpose is a liquid, actively-traded contract expiration, as defined or identified by the relevant trading facility or, if no such definition or identification is provided by the relevant trading facility, as defined by standard custom and practice in the industry.

If a Futures Exchange ceases trading in all contract expirations relating to a particular Benchmark Component Metals Futures Contract, SummerHaven Indexing may designate a replacement contract on the particular metal. The replacement contract must satisfy the eligibility criteria for inclusion in the Metals Index. To the extent practicable, the replacement will be effected during the next monthly review of the composition of the Metals Index. If that timing is not practicable, SummerHaven Indexing will determine the date of the replacement based on a number of factors, including the differences between the existing Benchmark Component Metals Futures Contract and the replacement contract with respect to contractual specifications and contract expirations.

If a Benchmark Component Metals Futures Contract is eliminated and there is no replacement contract, the underlying metal will necessarily drop out of the Metals Index. The designation of a replacement contract, or the elimination of a metal from the Metals Index because of the absence of a replacement contract, could affect the value of the Metals Index, either positively or negatively, depending on the price of the contract that is eliminated and the prices of the remaining contracts. It is impossible, however, to predict the effect of these changes, if they occur, on the value of the Metals Index.

Commodity Weighting

Each of the Benchmark Component Metals Futures Contracts will remain in the Metals Index from month to month. Weights for each of the Benchmark Component Metals Futures Contracts are determined for the next month. The methodology used to calculate the Metals Index weighting is based solely on quantitative data using observable futures prices and is not subject to human bias.

The monthly weighting selection is a three-step process based upon examination of the relevant futures prices for each metal:

1) The annualized percentage price difference between the closest-to-expiration Benchmark Component Metals Futures Contract and the next closest-to-expiration Benchmark Component Metals Futures Contract is calculated for each of the 10 eligible metals on USMI’s Selection Date (“USMI’s Selection Date”). The three metals with the highest percentage price difference are selected.

2) For the remaining seven eligible metals, the percentage price change of each metal over the previous year is calculated, as measured by the change in the price of the closest-to-expiration Benchmark Component Metals Futures Contract on the Selection Date from the price of the closest-to-expiration Benchmark Component Metals Futures Contract a year prior to USMI’s Selection Date. The two metals with the highest percentage price change are selected.

3) For the five metals selected through basis (step 1) and momentum (step 2), each metal’s weight is increased by 3% above its base weighting for the following month. For the remaining five metals not selected, each metal’s weight is decreased by 3% below its base weighting for the following month.

Due to the dynamic monthly metal weighting calculation, the individual metal weights will vary over time, depending on the price observations each month. USMI’s Selection Date for the Metals Index is the fifth business day prior to the first business day of the next calendar month.

27

The following graph shows the metal weights of the metals selected for inclusion in the Metals Index as of December 31, 2012.

Contract Selection

For each metal in the Metals Index, the index selects a specific Benchmark Component Metals Futures Contract with a tenor (i.e., contract month) among the eligible tenors (the range of contract months) based upon the relative prices of the Benchmark Component Metals Futures Contract within the eligible range of contract months. The previous notwithstanding, the contract expiration is not changed for that month if a Benchmark Component Metals Futures Contract remains in the Metals Index, as long as the contract does not enter expire or enter its notice period in the subsequent month.

Portfolio Construction

The portfolio rebalancing takes place during the Rebalancing Period. At the end of each of the days in the Rebalancing Period one fourth of the prior month portfolio positions are replaced by the new metals weights for the Benchmark Component Metals Futures Contract determined on USMI’s Selection Date.

Metals Index Total Return Calculation

The value of the Metals Index on any business day is equal to the product of (i) the value of the Metals Index on the immediately preceding business day multiplied by (ii) one plus the sum of the day’s returns for another version of the Metals Index known as the SummerHaven Dynamic Metals Index Excess Return “SDMI ER” (explained below) and one business day’s interest from the hypothetical Treasury Bill portfolio. The value of the Metals Index will be calculated and published by the NYSE Arca.

Metals Index Base Level

The Metals Index was set to 100 on January 2, 1991.

SDMI ER Calculation

The total return of the SDMI ER reflects the percentage excess return equals the percentage change of the market values of the underlying Benchmark Component Metals Futures Contracts. During the Rebalancing Period, the Metals Index changes its contract holdings and weightings during a four day period. The value of the SDMI ER at the end of a business day “t” is equal to the SDMI ER value on day “t-1” multiplied by the sum of the daily percentage price changes of each commodity future factoring in each respective commodity future’s notional holding on day “t-1”.

28

Rebalancing Period

During the Rebalancing Period, existing positions are replaced by new positions based on the signals used for contract selection as outlined above. At the end of the first day of the Rebalancing Period, the signals are observed and on the second day a new portfolio is constructed that is equally weighted in terms of notional positions in the newly selected contracts.

Holiday Schedule

The Metals Index will not be computed on the following weekdays in 2013:

January	1
January	21
February	18
March	29
May	27
July	4
September	2
November	28

The holiday schedule is subject to change. USMI will not accept Creation Baskets or Redemption Baskets on these days.

What Are Over-the-Counter Derivatives (Including Spreads and Straddles)?

In addition to Futures Contracts and options on Futures Contracts, derivative contracts that are tied to various commodities are entered into outside of public exchanges. These “over-the-counter” contracts are entered into between two parties in private contracts. Unlike most of the exchange-traded futures contracts or exchange-traded options on futures contracts, each party to such a 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, each Trust Series may enter into an agreement with each counterparty based on the Master Agreement published by the International Swaps and Derivatives Association, Inc. 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.

Each Trust Series 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 Applicable Benchmark Component Futures Contracts. Each Trust Series 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.

None of the Trust Series has employed any hedging methods since all of its investments have been made over an exchange. Therefore, none of the Trust Series has been exposed to counterparty risk.

Treasuries, Cash and Cash Equivalents

Each Trust Series seeks to have the aggregate “notional” amount of the Applicable Interests it holds approximate at all times its aggregate NAV. At any given time, however, most of the Trust Series holdings are in short-term Treasuries, cash and/or cash equivalents that support such Trust Series’ positions in Applicable Interests. For example, the purchase of an Applicable Benchmark Component Futures Contract with a stated or notional amount of $10 million would not require a Trust Series to pay $10 million upon entering into the contract; rather, only a margin deposit, generally of 5% to 30% of the notional amount, would be required. To secure its obligations under Applicable Benchmark Component Futures Contracts, a Trust Series would deposit the required margin with the FCM and would separately hold its remaining assets through its Custodian in Treasuries, cash and/or cash equivalents. Such remaining assets may be used to meet future margin payments that a Trust Series is required to make on its Applicable Benchmark Component Futures Contracts. Other Related Investments typically also involve collateral requirements that represent a small fraction of their notional amounts, so most of a Trust Series’ assets dedicated to Other Related Investments will also be held in Treasuries, cash and cash equivalents.

29

Each of the Trust Series earns income from the Treasuries and/or cash equivalents that it purchases and on the cash it holds through the Custodian. USCF anticipates that the earned income will increase each Trust Series’ NAV. Each Trust Series applies the earned income to the acquisition of additional investments or uses it to pay its expenses. If a Trust Series reinvests the earned income, it makes investments that are consistent with its investment objective.

What are the Trading Policies of the Trust Series?

Liquidity

Each Trust Series invests only in Applicable Benchmark Component Futures Contracts 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 Applicable Interests that, in the opinion of USCF, may be readily liquidated with the original counterparty or through a third party assuming a Trust Series’ position.

Spot Commodities

While certain futures contracts can be physically settled, none of the Trust Series intends to take or make physical delivery. However, a Trust Series may from time to time trade in Other Related Investments based on the spot price of the applicable commodities comprising the Applicable Index.

Leverage

USCF endeavors to have the value of a Trust Series’ Treasuries, cash and cash equivalents, whether held by a Trust Series or posted as margin or other collateral, at all times approximate the aggregate market value of its obligations under its Applicable Interests and Other 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 does not intend to leverage the assets of any Trust Series, it is not prohibited from doing so under the Trust Agreement.

Borrowings

Borrowings are not used by any Trust Series unless it is required to borrow money in the event of physical delivery, if it trades in cash commodities, or for short-term needs created by unexpected redemptions. None of the Trust Series plans to establish credit lines.

Pyramiding

None of the Trust Series has, 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 each Trust Series, BBH&Co. may hold each Trust Series’ Treasuries, cash and/or cash equivalents pursuant to a custodial agreement.

In March 2008, NFI settled, without admitting or denying the allegations, a disciplinary action brought by the NYMEX alleging that NFI violated NYMEX rules related to: numbering and time stamping orders by failing properly to record a floor order ticket; wash trading; failure to adequately supervise employees; and violation of a prior NYMEX cease and desist order, effective as of December 5, 2006, related to numbering and time stamping orders and block trades. NFI paid a $100,000 fine to NYMEX in connection with this settlement.

In February 2011, Newedge USA settled, without admitting or denying the allegations, a disciplinary action brought by the CFTC alleging that Newedge USA exceeded speculative limits in the October 2009 live cattle futures contract on the Chicago Mercantile Exchange and failed to provide accurate and timely reports to the CFTC regarding their larger trader positions. Newedge USA paid a $140,000 civil penalty and disgorgement value of $80,910 to settle this matter. In addition, the CFTC Order required Newedge USA to implement and maintain a program designed to prevent and detect reporting violations of the CEA and CFTC regulations.

In January 2012, Newedge USA settled, without admitting or denying the allegations, a disciplinary action brought by the CFTC alleging that Newedge USA failed to file accurate and timely reports to the CFTC and failed to report certain large trader information to the CFTC. Newedge USA paid a $700,000 civil penalty to settle this matter. In addition, the CFTC Order required Newedge USA to timely submit accurate position reports and notices, and to implement and maintain procedures to prevent and detect reporting violations of the CEA and CFTC regulations.

Other than the foregoing proceedings, which did not have a material adverse effect upon the financial condition of Newedge USA, there have been no material administrative, civil or criminal actions brought, pending or concluded against Newedge USA or its principals in the past five years.

Neither Newedge USA, nor any affiliate, officer, director or employee thereof have passed on the merits of this annual report on Form 10-K, or give any guarantee as to the performance or any other aspect of the Trust Series.

⁽²⁴⁾ USCF has voluntarily agreed to pay certain expenses typically borne by USMI to the extent that such expenses exceeded 0.15% (15 basis points) of USMI’s NAV, on an annualized basis, through at least June 30, 2013. USCF has no obligation to continue such payments into subsequent periods.

Other Fees. USMI also pays the fees and expenses associated with its tax accounting and reporting requirements. These fees were approximately $75,000 for the period ended December 31, 2012. In addition, USMI is responsible for paying its portion of the directors’ and officers’ liability insurance for USMI, the other Trust Series and the Related Public Funds. In addition, as of July 8, 2011, USMI became responsible for paying the fees and expenses of the independent directors who also serve as audit committee members of USMI, the other Trust Series and the Related Public Funds. USMI shares the fees and expenses on a pro rata basis with the Trust Series and 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, 2012 were $540,586 for the Trust Series and the Related Public Funds. USMI’s portion of such fees and expenses was $154.

Form of Units

Registered Form. Units are issued in registered form in accordance with the Trust Agreement. The Administrator has been appointed registrar and transfer agent for the purpose of transferring units in certificated form. The Administrator keeps a record of all unitholders and holders of the units in certificated form in the registry (the “Register”). The beneficial interests in such units 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 units. Instead, units 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 units outstanding at any time. Unitholders 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 units through DTC Participants or Indirect Participants, in each case who satisfy the requirements for transfers of units. DTC Participants acting on behalf of investors holding units through such participants’ accounts in DTC will follow the delivery practice applicable to securities eligible for DTC’s Same-Day Funds Settlement System. Units are credited to DTC Participants’ securities accounts following confirmation of receipt of payment.

DTC. DTC has advised the Trust Series 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.

Inter-Series Limitation on Liability

Because the Trust was established as a Delaware statutory trust, each Trust Series will be operated so that it will be liable only for obligations attributable to such series and will not be liable for obligations of any other series or affected by losses of any other series. If any creditor or unitholder of any particular series asserts against the series a valid claim with respect to its indebtedness or units, the creditor or unitholder will only be able to obtain recovery from the assets of that series and not from the assets of any other series or the Trust generally. The assets of each Trust Series will include only those funds and other assets that are paid to, held by or distributed to the series on account of and for the benefit of that series, including, without limitation, amounts delivered to the Trust for the purchase of units in a series. This limitation on liability is referred to as the Inter-Series Limitation on Liability. The Inter-Series Limitation on Liability is expressly provided for under the Delaware Statutory Trust Act, which provides that if certain conditions (as set forth in Section 3804(a)) are met, then the debts of any particular series will be enforceable only against the assets of such series and not against the assets of any other series or the Trust generally. In furtherance of the Inter-Series Limitation on Liability, every party providing services to the Trust, any Trust Series or USCF on behalf of the Trust or any Trust Series, will acknowledge and consent in writing to the Inter-Series Limitation on Liability with respect to such party’s claims.

36

The existence of a Trustee should not be taken as an indication of any additional level of management or supervision over any Trust Series. To the greatest extent permissible under Delaware law, the Trustee acts in an entirely passive role, delegating all authority for the management and operation of each Trust Series and the Trust to USCF. The Trustee does not provide custodial services with respect to the assets of any Trust Series.

Calculating Per Unit NAV

Each Trust Series’ per unit NAV is calculated by:

• Taking the current market value of its total assets;

• Subtracting any liabilities; and

• Dividing that total by the total number of outstanding units.

The Administrator calculates the per unit NAV of each Trust Series once each NYSE Arca trading day. The per unit NAV for a particular trading day is released after 4:00 p.m. New York time. Trading during the core trading session on the NYSE Arca typically closes at 4:00 p.m. New York time. The Administrator uses the closing prices on the relevant Futures Exchanges of the Applicable Benchmark Component Futures Contracts (determined at the earlier of the close of such exchange or 2:30 p.m. New York time) for the Futures Contracts traded on the Futures Exchanges, but calculates or determines the value of all other investments of a Trust Series (including Other Related Investments) 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 Administrative Agency Agreement among BBH&Co., the Trust Series 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 a Trust Series 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 each Trust Series 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 unit NAV of a Trust Series as a base and updating that value throughout the trading day to reflect changes in the most recently reported price level of the Applicable Index as reported by Bloomberg or other reporting service.

The indicative fund value unit basis disseminated during NYSE Arca core trading session hours should not be viewed as an actual real time update of the per unit NAV, because the per unit NAV is calculated only once at the end of each trading day based upon the relevant end of day values of each Trust Series’ investments.

The indicative fund value is disseminated on a per unit 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 Futures Exchanges vary, with some Futures Exchanges ending their trading hours before the close of the core trading session on NYSE Arca (for example, the normal trading hours of the NYMEX are 10:00 a.m. New York time to 2:30 p.m. New York time). When a Trust Series holds Applicable Benchmark Component Futures Contracts from Futures Exchanges with different trading hours than the NYSE Arca, there will be a gap in time at the beginning and/or the end of each day during which such Trust Series’ units are traded on the NYSE Arca, but real-time Futures Exchange trading prices for Applicable Benchmark Component Futures Contracts traded on such Futures Exchanges are not available. During such gaps in time the indicative fund value– will be calculated based on the end of day price of such Applicable Benchmark Component Futures Contracts from Futures Exchanges immediately preceding trading session. In addition, Other Related Investments and Treasuries held by a Trust Series 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.

37

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

In addition, other Futures Contracts, Other Related Investments and Treasuries held by a Trust Series are 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 are not included in the indicative value. The indicative fund value is based on the prior day’s per unit NAV and moves up and down solely according to changes in the price of the Applicable Index as reported on Bloomberg or another reporting service.

Creation and Redemption of Units

Each Trust Series creates and redeems units 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 a Trust Series or the distribution by a Trust Series of the amount of Treasuries and/or cash represented by the baskets being created or redeemed, the amount of which is equal to the combined NAV of the number of units included in the baskets being created or redeemed determined as of 4:00 p.m. New York time on the day the order to create or redeem baskets is properly received.

Authorized Purchasers are the only persons that may place orders to create and redeem baskets. Authorized Purchasers must be (1) either 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 Purchaser, a person must enter into an Authorized Purchaser Agreement with USCF on behalf of a Trust Series. The Authorized Purchaser Agreement provides the procedures for the creation and redemption of baskets and for the delivery of the Treasuries and/or cash required for such creations and redemptions. The Authorized Purchaser Agreement and the related procedures attached thereto may be amended by USCF, without the consent of any unitholder or Authorized Purchaser. From July 1, 2011 through May 1, 2013, Authorized Purchasers pay USCI $350 for each order placed to create one or more Creation Baskets or to redeem one or more Redemption Baskets; prior to July 1, 2011, Authorized Purchasers paid USCI $1,000 for each order placed to create one or more Creation Baskets or to redeem one or more Redemption Baskets. From May 1, 2012 through May 1, 2013, Authorized Purchasers pay each of CPER, USAG and USMI $350 for each order placed to create one or more Creation Baskets or to redeem one or more Redemption Baskets; prior to May 1, 2012, Authorized Purchasers paid $1,000 for each order placed to create one or more Creation Baskets or to redeem one or more Redemption Baskets. Authorized Purchasers who make deposits with a Trust Series in exchange for baskets receive no fees, commissions or other form of compensation or inducement of any kind from either the Trust or USCF, and no such person will have any obligation or responsibility to the Trust or USCF to effect any sale or resale of units. As of December 31, 2012, 6 Authorized Purchasers had entered into agreements with USCF on behalf of each of USCI. During the year ended December 31, 2012, USCI issued 45 Creation Baskets and redeemed 8 Redemption Baskets. As of December 31, 2012, 6 Authorized Purchasers had entered into agreements with USCF on behalf of CPER. During the year ended December 31, 2012, CPER issued 1 Creation Basket and redeemed 1 Redemption Basket. As of December 31, 2012, 6 Authorized Purchasers had entered into agreements with USCF on behalf of USAG. During the year ended December 31, 2012, USAG issued 3 Creation Baskets and redeemed 2 Redemption Baskets. As of December 31, 2012, 6 Authorized Purchasers had entered into agreements with USCF on behalf of USMI. During the year ended December 31, 2012, USMI issued 3 Creation Baskets and redeemed 1 Redemption Basket.

38

Certain Authorized Purchasers are expected to be capable of participating directly in the applicable physical commodity and the Applicable Interest markets. Some Authorized Purchasers or their affiliates may from time to time buy or sell applicable commodities or Applicable Interests and may profit in these instances. USCF believes that the size and operation of the applicable commodities market make it unlikely that Authorized Purchasers’ direct activities in the applicable commodities or securities markets will significantly affect the price of applicable commodities, Applicable Interests, or the price of units.

Each Authorized Purchaser 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 Purchasers may also be regulated under federal and state banking laws and regulations. Each Authorized Purchaser 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 Purchaser Agreement, USCF has agreed to indemnify the Authorized Purchasers against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”), and to contribute to the payments the Authorized Purchasers 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 Trust Agreement and the form of Authorized Purchaser 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 Purchaser 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 the NYSE Arca, the New York Stock Exchange, or any of the Futures Exchanges upon which a Applicable Benchmark Component Futures Contract is traded is closed for regular trading. Purchase orders must be placed by 10:30 a.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 Purchaser agrees to deposit Treasuries, cash or a combination of Treasuries and cash with the Trust, as described below. Prior to the delivery of baskets for a purchase order, the Authorized Purchaser must also have wired to the Custodian the non-refundable transaction fee due for the purchase order. Authorized Purchasers may not withdraw a creation request.

The manner by which creations are made is dictated by the terms of the Authorized Purchaser Agreement. By placing a purchase order, an Authorized Purchaser 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 a Trust Series 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 Purchaser 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 a Trust Series’ investment objective and shall be purchased as a result of the Authorized Purchaser’s purchase of units.

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 a Trust Series (net of estimated accrued but unpaid fees, expenses and other liabilities) on the purchase order date as the number of units to be created under the purchase order is in proportion to the total number of units outstanding on the purchase order dates. USCF determines, directly in its sole discretion or in consultation with the Administrator, the requirements for Treasuries and cash, including the remaining maturities of the Treasuries and proportions of Treasuries and cash that may be included in deposits to create baskets. The Marketing Agent will publish an estimate of the Creation Basket Deposit requirements at the beginning of each business day.

39

Delivery of Required Deposits

An Authorized Purchaser who places a purchase order is responsible for transferring to a Trust Series’ account with the Custodian the required amount of Treasuries and/or cash by noon New York time on 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 Purchaser’s DTC account on the third business day following the purchase order date.

Because orders to purchase baskets must be placed by 10:30 a.m., New York time, but the total payment required to create a basket during the continuous offering period will not be determined until 4:00 p.m., New York time, on the date the purchase order is received, Authorized Purchasers 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. A Trust Series’ per unit 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 shall have no obligation, to reject any purchase order or Creation Basket Deposit if USCF determines that:

• the purchase order or Creation Basket Deposit is not in proper form;

• it would not be in the best interest of the unitholders of a Trust Series;

• due to position limits or otherwise, investment alternatives that will enable a Trust Series to meet its investment objective are not available to such Trust Series at that time;

• the acceptance of the purchase order or the Creation Basket Deposit would have adverse tax consequences to a Trust Series or its unitholders;

• the acceptance or receipt of which would, in the opinion of counsel to USCF, be unlawful; or

• circumstances outside the control of USCF, the Marketing Agent or the Custodian make it, for all practical purposes, not feasible to process creations of Creation Baskets (including if USCF determines that the investments available to a Trust Series at that time will not enable it to meet its investment objective).

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 Purchaser can redeem one or more baskets mirror the procedures for the creation of baskets. On any business day, an Authorized Purchaser may place an order with the Marketing Agent to redeem one or more baskets. Redemption orders must be placed by 10:30 a.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. The redemption procedures allow Authorized Purchasers to redeem baskets and do not entitle an individual unitholder to redeem any units in an amount less than a Redemption Basket, or to redeem baskets other than through an Authorized Purchaser.

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

The manner by which redemptions are made is dictated by the terms of the Authorized Purchaser Agreement. By placing a redemption order, an Authorized Purchaser agrees to (1) deliver the Redemption Basket to be redeemed through DTC’s book-entry system to a Trust Series’ 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 transaction (through itself or a designated acceptable broker) with a Trust Series 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 Purchaser 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 a Trust Series’ investment objective and shall be sold as a result of the Authorized Purchaser’s sale of units.

40

Determination of Redemption Distribution

The redemption distribution from a Trust Series consists of a transfer to the redeeming Authorized Purchaser of an amount of Treasuries and/or cash that is in the same proportion to the total assets of such Trust Series (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 units to be redeemed under the redemption order is in proportion to the total number of units outstanding on the date the order is received. USCF, directly or in consultation with the Administrator, determines the requirements for Treasuries and cash, including the remaining maturities of the Treasuries and 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 a Trust Series will be delivered to the Authorized Purchaser on the third business day following the redemption order date if, by 3:00 p.m., New York time on such third business day, such Trust Series’ DTC account has been credited with the baskets to be redeemed. If such Trust Series’ 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 USCF 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 a Trust Series’ 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 a Trust Series’ DTC account by 3:00 p.m., New York time on the third business day following the redemption order date if the Authorized Purchaser 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 any of the Futures Exchanges upon which an Applicable Benchmark Component Futures Contract is traded is closed other than customary weekend or holiday closings, or trading on the NYSE Arca or the Futures Exchanges 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 unitholders. For example, USCF may determine that it is necessary to suspend redemptions to allow for the orderly liquidation of a Trust Series’ assets at an appropriate value to fund a redemption. If USCF has difficulty liquidating a Trust Series’ positions, e.g., because of a market disruption event in the futures markets 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 Purchaser Agreement, or the fulfillment of the order in the opinion of its counsel may be illegal under applicable laws and regulations, or if circumstances outside the control of USCF, the Marketing Agent or the Custodian make it for all practical purposes not feasible for the units to be delivered under the Redemption Order. USCF may also reject a redemption order if the number of units being redeemed would reduce the remaining outstanding units to 100,000 units (i.e., two baskets) or less.

41

Creation and Redemption Transaction Fee

To compensate each Trust Series for its expenses in connection with the creation and redemption of baskets, an Authorized Purchaser is required to pay a transaction fee to each Trust Series per order to create or redeem baskets, regardless of the number of baskets in such order. From July 1, 2011 through May 1, 2013, Authorized Purchasers pay USCI $350 for each order placed to create one or more Creation Baskets or to redeem one or more Redemption Baskets; prior to July 1, 2011, Authorized Purchasers paid USCI $1,000 for each order placed to create one or more Creation Baskets or to redeem one or more Redemption Baskets. From May 1, 2012 through May 1, 2013, Authorized Purchasers pay each of CPER, USAG and USMI $350 for each order placed to create one or more Creation Baskets or to redeem one or more Redemption Baskets; prior to May 1, 2012, Authorized Purchasers paid $1,000 for each order placed to create one or more Creation Baskets or to redeem one or more Redemption Baskets. 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 Purchasers 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 Purchaser, and agree to indemnify USCF and each Trust Series 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, each Trust Series creates and redeems units 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 a Trust Series or the distribution by a Trust Series of the amount of Treasuries and/or cash equal to the aggregate NAV of the number of units 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 Purchasers are the only persons that may place orders to create and redeem baskets. Authorized Purchasers 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 Purchaser is under no obligation to create or redeem baskets, and an Authorized Purchaser is under no obligation to offer to the public units of any baskets it does create. Authorized Purchasers that do offer to the public units from the baskets they create will do so at per-unit offering prices that are expected to reflect, among other factors, the trading price of the units on the NYSE Arca, the NAV of a Trust Series’ units at the time the Authorized Purchaser purchased the Creation Baskets, the per unit NAV of the units at the time of the offer of the units to the public, the supply of and demand for units at the time of sale, and the liquidity of the Applicable Benchmark Component Futures Contract market and the market for Other Related Investments. Baskets are generally redeemed when the price per unit is at a discount to the per unit NAV.

Units initially comprising the same basket but offered by Authorized Purchasers to the public at different times may have different offering prices. An order for one or more baskets may be placed by an Authorized Purchaser on behalf of multiple clients. Units trade in the secondary market on the NYSE Arca. Units may trade in the secondary market at prices that are lower or higher relative to their per unit NAV. The amount of the discount or premium in the trading price relative to the per unit NAV may be influenced by various factors, including the number of investors who seek to purchase or sell units in the secondary market and the liquidity of the Applicable Benchmark Component Futures Contract market and the market for Other Related Investments. While the units trade during the core trading session on the NYSE Arca until 4:00 p.m. New York time, liquidity in the market for Applicable Benchmark Component Futures Contracts and Other Related Investments may be reduced after the close of the Futures Exchanges upon which the Applicable Benchmark Component Futures Contracts are traded. As a result, during this time, trading spreads, and the resulting premium or discount, on the units may widen.

Who is the Trustee?

The sole Trustee of the Trust is Wilmington Trust Company, a Delaware trust company (the “Trustee”). The Trustee’s principal offices are located at 1100 North Market Street, Wilmington, Delaware 19890-0001. The Trustee is unaffiliated with USCF. The Trustee’s duties and liabilities with respect to the offering of units and the management of the Trust and each Trust Series are limited to its express obligations under the Trust Agreement.

42

The Trustee will accept service of legal process on the Trust in the State of Delaware and will make certain filings under the Delaware Statutory Trust Act. The Trustee does not owe any other duties to the Trust, USCF or the unitholders. The Trustee is permitted to resign upon at least sixty (60) days’ notice to USCF. If no successor trustee has been appointed by USCF within such sixty-day period, the Trustee may, at the expense of the Trust, petition a court to appoint a successor. The Trustee is entitled to reasonable compensation for its services from USCF or an affiliate of USCF (including the Trust), and is indemnified by USCF against any expenses it incurs relating to or arising out of the formation, operation or termination of the Trust, or any action or inaction of the Trustee under the Trust Agreement, except to the extent that such expenses result from the gross negligence or willful misconduct of the Trustee. USCF has the discretion to replace the Trustee.

Under the Trust Agreement, the Trustee has delegated to USCF the exclusive management and control of all aspects of the business of the Trust and the Trust Series. The Trustee has no duty or liability to supervise or monitor the performance of USCF, nor does the Trustee have any liability for the acts or omissions of USCF.

Because the Trustee has no authority over the operation of the Trust, the Trustee itself is not registered in any capacity with the CFTC.

Investments

USCF applies substantially all of a Trust Series’ assets in Applicable Benchmark Component Futures Contracts and Other Related Investments, short-term Treasuries, cash and cash equivalents. When a Trust Series purchases Applicable Benchmark Component Futures Contracts and certain Other Related Investments that are exchange-traded, a Trust Series is required to deposit with the 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 the Applicable Interests at maturity. This deposit is known as initial margin. Counterparties in transactions in over-the-counter Applicable Interests generally impose similar collateral requirements on a Trust Series. USCF invests a Trust Series’ assets that remain after margin and collateral is 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 will be:

• held as margin or collateral with FCMs or other custodians;

• used for other investments; and

• held in bank accounts to pay current obligations and as reserves.

In general, a Trust Series posts between 5% to 30% of the notional amount of an Applicable Interest as initial margin when entering into such Applicable Interest. Ongoing margin and collateral payments will generally be required for both exchange-traded and over-the-counter Applicable Interests based on changes in the value of the Applicable Interests. Furthermore, ongoing collateral requirements with respect to over-the-counter Applicable 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 the Applicable Interest, and each party’s creditworthiness. In light of the differing requirements for initial payments under exchange-traded and over-the-counter Applicable Interests and the fluctuating nature of ongoing margin and collateral payments, it is not possible to estimate what portion of a Trust Series’ assets will be posted as margin or collateral at any given time. The Treasuries, cash and cash equivalents held by a Trust Series constitute reserves that are available to meet ongoing margin and collateral requirements. All income is used for a Trust Series’ benefit.

An FCM, counterparty, government agency or commodity exchange could increase margin or collateral requirements applicable to a Trust Series 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.

Each Trust Series’ assets posted as margin for Futures Contracts will be held in segregated accounts pursuant to CEA and CFTC regulations. Collateral posted in connection with over-the-counter contracts held with a Trust Series’ FCM will be similarly segregated and if held with other counterparties will be segregated pursuant to contract between such Trust Series and its counterparties.

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 units of each Trust Series as well as units of each of the Related Public Funds, is registered under the Securities Act. Each Trust Series 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. The Firm’s participation in the distribution of units 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 over-the-counter 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.

44

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 a Trust Series 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 will be regulated by the CFTC once the Dodd-Frank Act is fully implemented. At a minimum, over-the-counter currency forwards, options and swaps will be subject to heightened recordkeeping, reporting and business conduct standards.

On November 16, 2012, the Secretary of the Treasury issued a final determination that 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 the Trust Series to a risk of default since failure of a bank with which a Trust Series had entered into a forward contract would likely result in a default and thus possibly substantial losses to the Trust Series.

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.

45

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.

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, the Trust Series 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 unitholders 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. Unitholders 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.

46

The CEA requires all FCMs, such as USCI’s, CPER’s, USAG’s or USMI’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.

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

Each Trust Series’ 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, as exemplified by the various discussions of the Dodd-Frank Act. The various statements made in this summary are subject to modification by legislative action and changes in the rules and regulations of the CFTC, the 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.

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

47

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

“Swap” Transactions

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

The Dodd-Frank Act requires that certain transactions ultimately falling within the definition of “swap” be executed on organized exchanges or “swap execution facilities” and cleared through regulated clearing organizations (which are referred to in the Dodd-Frank Act as “derivative clearing organizations” (“DCOs”)), if the CFTC mandates the central clearing of a particular contract. On November 28, 2012, the CFTC issued its final clearing determination requiring that certain credit default swaps and interest rate swaps be cleared by registered DCOs. This is the CFTC’s first clearing determination under the Dodd-Frank Act and became effective on February 11, 2013. Determination on other types of swaps are expected in the future, and, when finalized, could required each Trust Series to centrally clear certain over-the-counter instruments presently entered into and settled on a bi-lateral basis. If a swap is required to be cleared, the initial margin will be set by the clearing organization, subject to certain regulatory requirements and guidelines. Initial and variation margin requirements for swap dealers and major swap participants who enter into uncleared swaps and capital requirements for swap dealers and major swap participants who enter into both cleared and uncleared trades will be set by the CFTC, the SEC or the applicable “Prudential Regulator.” On May 23, 2012, the CFTC published final regulations, which became effective as of July 23, 2012, to determine which entities will be regulated as “swap dealers” and “major swap participants” and thus have to comply with these capital and margin requirements (as well as a multitude of other requirements under the Dodd-Frank Act). Most of the requirements imposed became effective on October 12, 2012, when additional final rules defining the terms “swap,” “security-based swap,” and “mixed swap” became effective. However, on October 11, 2012 and October 12, 2012, the CFTC issued several no-action letters and interpretive guidance which delayed much of the implementation of the requirements from October 12, 2012 until December 31, 2012. Increased regulation of, and the imposition of additional costs on, swap transactions could have an adverse effect on a Trust Series by, for example, reducing the size of and therefore liquidity in the derivatives market, increasing transaction costs and decreasing the ability to customize derivative transactions.

On February 7, 2012, the CFTC published a rule requiring each FCM and DCO to segregate cleared swaps and related collateral posted by a customer of the FCM from the assets of the FCM or DCO, although such property can be commingled with the property of other cleared swaps customers of the FCM or DCO. This rule addresses losses incurred by a DCO in a so-called “double default” scenario in which a customer of an FCM defaults in its obligations to the FCM and the FCM, in turn, defaults in its obligations to the DCO. Under this scenario, the DCO can only access the collateral attributable to other customers of the DCO whose cleared swap positions are in a loss position following the primary customer’s default. This became effective on November 8, 2012. Some market participants have expressed concern that the requirements of this segregation rule may result in higher initial margins or higher fees. The Trust Series do not anticipate any impact to their operations in order to meet the requirements of the new rule.

Additionally, the CFTC published rules on February 17, 2012 and April 3, 2012 that require “swap dealers” and “major swap participants” to: 1) adhere to business conduct standards, 2) implement policies and procedures to ensure compliance with the CEA and 3) maintain records of such compliance. These new requirements may impact the documentation requirements for both cleared and non-cleared swaps and cause swap dealers and major swap participants to face increased compliance costs that, in turn, may be passed along to counterparties (such as a Trust Series) in the form of higher fees and expenses that related to trading swaps.

48

On February 24, 2012, the CFTC amended certain disclosure obligations to require that the operator of a commodity pool that invests in swaps include standardized swap risk disclosures in the pool’s disclosure documents by December 31, 2012.

The CFTC issued a final rule on May 23, 2012 interpreting the definition of “eligible contract participant,” as amended by the Dodd-Frank Act, in such a manner that a Trust Series may be limited as to the counterparties with which it may enter into forward contracts. Additionally, a Trust Series may under certain circumstances related to the amount of assets under management no longer qualify as an eligible contract participant. A Trust Series’ ability to maintain a certain minimum level of assets and to qualify as an eligible contract participant allows such Trust Series to enter into swaps on swap execution facilities as well as on a bilateral, off-exchange basis. The loss of status as an eligible contract participant and the resulting loss of eligible counterparties and investment options could impact a Trust Series’ ability to achieve its investment objective.

On December 5, 2012, the CFTC’s Division of Market Oversight issued a letter providing swap dealers with time-limited no-action relief from swap data reporting obligations with respect to equity swaps, foreign exchange swaps and other commodity swaps. For these asset classes, the letter provides swap dealers with reporting relief (i) with respect to real-time price reporting and regular swap reporting (under Part 43 and Part 45 of the CFTC’s regulations, respectively), until February 28, 2013, and (ii) historical swap reporting requirements (under Part 46 of the CFTC’s regulations) until March 30, 2013.

On December 21, 2012, the CFTC’s Division of Market Oversight issued two letters providing certain swap dealers with time-limited no-action relief from some swap data reporting obligations. One letter provides relief from reporting requirements for branches of swap dealers located in emerging markets who encounter technical difficulties in complying with the reporting rules. The letter also provides that swap dealers may delay reporting compliance for certain complex and exotic swaps until April 30, 2012.

Under a second letter, all swap dealers have until April 10, 2013 to report certain information about their counterparties, including: status as a major swap participant, a financial entity, a U.S. person or a commercial end-user.

On December 18, 2012, the CFTC deferred the compliance date for many of the Dodd-Frank Act’s external business conduct standards from December 31, 2012 to May 1, 2013, and for some requirements to July 1, 2013, providing swap dealers an additional four to six months from the original compliance date.

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

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 the Trust Series’ 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 a Trust Series 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.

49

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, a Trust Series 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 a Trust Series’ trading, a Trust Series (and not its investors personally) is subject to margin calls.

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.

Item 1A. Risk Factors.

The 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 the financial statements and the related notes.

Risks Associated With Investing Directly or Indirectly in Indices and Applicable Interests

Historical Performance of each Applicable Index is no guide to the future performance of the units.

Past performance of each Applicable Index is not necessarily indicative of the future performance of such Applicable Index over the life of the units. There can be no guarantee that the level of each Applicable Index will increase. Investors may lose some or all of their investment in the units.

Daily changes in a Trust Series’ per unit NAV may not correlate well with daily changes in the price of its Applicable Index. If this were to occur, investors may not be able to effectively use a Trust Series as a way to hedge against commodity-related losses or as a way to indirectly invest in commodities.

USCF endeavors to invest each Trust Series’ assets as fully as possible in Applicable Interests so that the daily changes in percentage terms in the per unit NAV closely correlate with the daily changes in percentage terms in the Applicable Index. However, daily changes in a Trust Series’ per unit NAV may not correlate with the daily changes in its Applicable Index for several reasons as set forth below:

• The Trust Series do not intend to invest only in Applicable Benchmark Component Futures Contracts. While its investments in Other Related Investments would generally be for the purpose of tracking the Applicable Index most effectively and efficiently, the performance of these Other Related Investments may not correlate well with the performance of the Applicable Benchmark Component Futures Contracts, resulting in a greater potential for error in tracking price changes in those futures contracts. If the trading market for the Applicable Benchmark Component Futures Contracts is suspended or closed, a Trust Series may not be able to purchase these investments at the last reported price for such investments.

• Each Trust Series incurs certain expenses in connection with its operations, and holds most of its assets in income-producing, short-term Treasuries, cash and/or cash equivalents for margin, collateral and other liquidity purposes and to meet redemptions that may be necessary on an ongoing basis. These expenses and income will cause imperfect correlation between changes in a Trust Series’ per unit NAV and changes in the Applicable Index.

• Each Trust Series buys and sells as many Applicable Interests that it can to get the daily changes in percentage terms of the per unit NAV as close as possible to the daily changes in percentage terms in the average price of the Applicable Index. The remainder of each Trust Series’ assets are invested in Treasuries, cash and/or cash equivalents and are used to satisfy initial margin and additional margin requirements, if any, and to otherwise support its investments in applicable commodity interests. Investments in Treasuries, cash and/or cash equivalents both, directly and indirectly and as margin, provide rates of return that vary from changes in the prices of the Applicable Benchmark Component Futures Contrasts.

51

• USCF may not be able to invest a Trust Series’ assets in Applicable Interests having an aggregate notional amount exactly equal to such Trust Series’ per unit NAV. As standardized contracts, the Applicable Benchmark Component Futures Contracts included in each Applicable Index are for a specified amount of a particular commodity, and each Trust Series’ per unit NAV and the proceeds from the sale of a Creation Basket are unlikely to be an exact multiple of the amounts of those contracts. In such case, a Trust Series could not invest the entire proceeds from the purchase of the Creation Basket in such futures contracts. For example, assuming USCI receives $4,679,000 for the sale of a Creation Basket and that the price of a natural gas Benchmark Component Futures Contract is $46,800, USCI could only invest in 99 Futures Contracts with an aggregate value of $4,633,200. The foregoing example is based upon the investment of proceeds from the sale of a Creation Basket into the Futures Contracts of a single commodity. The investment of proceeds from the sale of a Creation Basket by USCI, USAG and USMI may be more complex due to the fact that such Trust Series will use such proceeds to purchase Futures Contracts in multiple commodities. While a Trust Series may be better able to achieve the exact amount of exposure to the commodities market through the use of Other Related Investments such as over-the-counter contracts, there is no assurance that USCF will be able to continually adjust a Trust Series’ exposure to such Other Related Investments to maintain such exact exposure. Furthermore, as noted above, the use of Other Related Investments may itself result in imperfect correlation with the Applicable Index. After fulfilling the margin and collateral requirements with respect to a Trust Series’ Applicable Interests, USCF invests the remainder of a Trust Series’ proceeds from the sale of baskets in Treasuries or cash equivalents, and/or merely holds such assets in cash (generally, in interest-bearing accounts). Such investments may be used to satisfy initial margin and additional margin and collateral requirements, if any, and to otherwise support investments in Applicable Interests. Investments in Treasuries, cash and/or cash equivalents, both directly and as margin and collateral, will provide rates of return that vary from changes in the value of the price of commodities and the price of Applicable Benchmark Component Futures Contracts.

• As each Trust Series grows, there may be more or less correlation. At certain asset levels a Trust Series may be limited in its ability to purchase Applicable Benchmark Component Futures Contracts due to position limits imposed by the CFTC or position limits or accountability levels imposed by the relevant Futures Exchanges. In these instances, a Trust Series would likely invest to a greater extent in Applicable Interests not subject to these position limits or accountability levels. To the extent that a Trust Series invests in Other Related Investments, the correlation between a Trust Series’ NAV and its Applicable Index may be lower.

If daily changes in a Trust Series’ per unit NAV do not correlate with daily changes in its Applicable Index, then investing in a Trust Series may not be an effective way to hedge against commodity-related losses or indirectly invest in commodities.

Each Applicable Index is not designed to correlate exactly with the spot price of any commodity and this could cause the changes in the price of the units to substantially vary from the changes in the spot prices of the applicable commodities underlying the Applicable Benchmark Component Futures Contracts. Therefore, investors may not be able to effectively use a Trust Series to hedge against commodity-related losses or to indirectly invest in commodities.

Each Applicable Index reflects the price for future delivery of the applicable commodities underlying the Applicable Benchmark Component Futures Contracts, not the current spot prices of such applicable commodities, so at best the correlation between changes in such Applicable Benchmark Component Futures Contracts and the spot price of the underlying applicable commodities will be only approximate. Weak correlation between the Applicable Index and the spot prices of the applicable underlying commodities may result from the typical seasonal fluctuations in commodity prices. Imperfect correlation may also result from speculation in Applicable Interests, technical factors in the trading of Applicable Benchmark Component Futures Contracts, and expected inflation in the economy as a whole. If there is a weak correlation between the Applicable Index and the spot prices of the applicable underlying commodities, then the market price of units may not accurately track the spot price of such commodities and investors may not be able to effectively use a Trust Series as a way to hedge the risk of losses in their commodity-related transactions or as a way to indirectly invest in commodities.

A Trust Series may experience a loss if it is required to sell Treasuries or cash equivalents at a price lower than the price at which they were acquired.

The value of Treasuries and other debt securities generally moves inversely with movements in interest rates. The prices of longer maturity securities are subject to greater market fluctuations as a result of changes in interest rates. If a Trust Series is required to sell Treasuries at a price lower than the price at which they were acquired, a Trust Series will experience a loss. This loss may adversely impact the price of the units, and may decrease the correlation among the price of units, the per unit NAV of units, the Applicable Index and the spot price of the applicable commodities underlying the Applicable Benchmark Component Futures Contracts.

Certain of a Trust Series’ investments could be illiquid which could cause large losses to investors at any time or from time to time.

A Trust Series may not always be able to liquidate its positions in its investments at the desired price. As to futures contracts, it may be difficult to execute a trade at a specific price when there is a relatively small volume of buy and sell orders in a market. Limits imposed by futures exchanges or other regulatory organizations, such as accountability levels, position limits and price fluctuation limits, may contribute to a lack of liquidity with respect to some exchange-traded Applicable Interests. In addition, over-the-counter contracts may be illiquid because they are contracts between two parties and generally may not be transferred by one party to a third party without the counterparty’s consent. Conversely, a counterparty may give its consent, but a Trust Series still may not be able to transfer an over-the-counter Applicable Interest to a third party, e.g., due to concerns regarding the counterparty’s credit risk.

52

A market disruption, such as a foreign government taking political actions that disrupt the market in its currency, its commodity production or exports, or in another major export, can also make it difficult to liquidate a position. Unexpected market illiquidity may cause major losses to investors at any time or from time to time. In addition, none of the Trust Series intends at this time to establish a credit facility, which would provide an additional source of liquidity and instead relies only on the Treasuries, cash and/or cash equivalents that it holds. The anticipated large value of the positions in Applicable Interests that USCF will acquire or enter into for each Trust Series increases the risk of illiquidity. Because Applicable Interests may be illiquid, each Trust Series’ holdings 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.

If the nature of the participants in the futures market shifts such that commodity purchasers are the predominant hedgers in the market, a Trust Series might have to reinvest at higher futures prices or choose to invest in Other Related Investments.

The changing nature of the participants in the commodities market will influence whether futures prices are above or below the expected future spot price. Commodity producers will typically seek to hedge against falling commodity prices by selling futures contracts. Therefore, if commodity producers become the predominant hedgers in the futures market, prices of futures contracts will typically be below expected futures spot prices. Conversely, if the predominant hedgers in the futures market are the purchasers of the commodities who purchase futures contracts to hedge against a rise in prices, prices of futures contracts will likely be higher than expected future spot prices. This can have significant implications for a Trust Series when it is time to sell an Applicable Benchmark Component Futures Contract that is no longer part of the Applicable Index and purchase a new Applicable Benchmark Component Futures Contract that is part of its Applicable Index.

While the Trust Series do not intend to take physical delivery of commodities under their Applicable Interests, the possibility of physical delivery impacts the value of the contracts which would make it more difficult for a Trust Series to trade its Applicable Index and achieve its investment objective.

While it is not the current intention of any Trust Series to take physical delivery of commodities under their Applicable Interests, Applicable Benchmark Component Futures Contracts are traditionally not cash-settled contracts, and it is possible to take delivery under these and some Other Related Investments. Storage costs associated with purchasing commodities could result in costs and other liabilities that could impact the value of Applicable Benchmark Component Futures Contracts or Other Related Investments. Storage costs include the time value of money invested in a physical commodity plus the actual costs of storing the commodity less any benefits from ownership of the commodity that are not obtained by the holder of a futures contract. In general, Applicable Benchmark Component Futures Contracts have a one-month delay for contract delivery and back month contracts (the back month is any future delivery month other than the spot month) includes storage costs. To the extent that these storage costs change for commodities while a Trust Series holds its Applicable Interests, the value of the Applicable Interests, and therefore such Trust Series’ NAV, may change as well.

The price relationship between each Applicable Index at any point in time and the Futures Contacts that will become the Applicable Benchmark Component Futures Contracts on the next rebalancing date will vary and may impact both a Trust Series’ total return and the degree to which its total return tracks that of commodity price indices.

The design of each Applicable Index is such that every month it is made up of different Applicable Benchmark Component Futures Contracts, and a Trust Series’ investments must be rebalanced on an ongoing basis to reflect the changing composition of the Applicable Index. In the event of a commodity futures market where near month contracts to expire trade at a higher price than next month contracts to expire, a situation referred to as “backwardation,” then absent the impact of the overall movement in commodity prices, the value of the Applicable Index would tend to rise as it approaches expiration. As a result, a Trust Series may benefit because it would be selling more expensive contracts and buying less expensive ones on an ongoing basis. Conversely, in the event of a commodity futures market where near month contracts trade at a lower price than next month contracts, a situation referred to as “contango,” then absent the impact of the overall movement in commodity prices, the value of the Applicable Index would tend to decline as it approaches expiration. As a result, a Trust Series’ total return may be lower than might otherwise be the case because it would be selling less expensive contracts and buying more expensive ones. The impact of backwardation and contango may cause the total return of a Trust Series to vary significantly from the total return of other price references, such as the spot price of the commodities comprising the Applicable Index. In the event of a prolonged period of contango, and absent the impact of rising or falling commodity prices, this could have a significant negative impact on a Trust Series’ NAV and total return.

53

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

The futures markets are subject to comprehensive statutes, regulations, and margin requirements. In addition, the CFTC and the 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.

The 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 continued need to regulate the derivatives markets in general. The effect of any future regulatory change on each Trust Series 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 the Trust Series, please see “Item 1. Business – Regulation” in this annual report on Form 10-K.

Investing in a Trust Series for purposes of hedging may be subject to several risks, including the possibility of losing the benefit of favorable market movements.

Producers and commercial users of commodities may use a Trust Series as a vehicle to hedge the risk of losses in their commodity-related transactions. There are several risks in connection with using a Trust Series as a hedging device. While hedging can provide protection against an adverse movement in market prices, it can also preclude a hedger’s opportunity to benefit from a favorable market movement. For instance, in a hedging transaction the hedger may be a user of a commodity concerned that the hedged commodity will increase in price, but must recognize the risk that the price may instead decline. If this happens, he will have lost the benefit of being able to purchase the commodity at the lower price because the hedging transaction will result in a loss that would offset (at least in part) this benefit. Thus, the hedger forgoes the opportunity to profit from favorable price movements.

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

Historically, Applicable Interests have not generally been correlated to the performance of other asset classes such as stocks and bonds. Non-correlation means that there is a low statistical relationship between the performance of Applicable Interests, 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, a Trust Series’ 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 the units. In such a case, a Trust Series may have no gains to offset losses from other investments, and investors may suffer losses on their investment in a Trust Series while incurring losses with respect to other investments.

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

54

The Trust Series’ Operating Risks

None of the Trust Series is a registered investment company, so unitholders do not have the protections of the 1940 Act.

None of the Trust Series is 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.

USCF is leanly staffed and relies heavily on key personnel and its trading advisor, SummerHaven, to manage its activities.

In managing and directing the day-to-day activities and affairs of each Trust Series, USCF relies heavily on Messrs. Howard Mah and John Hyland. If Messrs. Mah or Hyland were to leave or be unable to carry out their present responsibilities, it may have an adverse effect on the management of a Trust Series. Furthermore, Messrs. Mah and Hyland are currently involved in the management of the Related Public Funds. USCF has also filed registration statements to register units of USSF, UNGD, USGO and UAC, each a series of the United States Commodity Funds Trust I, and HARD, a series of the United States Currency Funds Trust. Mr. Mah is also employed by Ameristock Corporation, a registered investment adviser that until January 11, 2013 managed a public mutual fund. On January 11, 2013, Ameristock Mutual Fund, Inc. was reorganized with and into the Drexel Hamilton Centre American Equity Fund, a series of the Drexel Hamilton Mutual Funds. Drexel Hamilton Mutual Funds and its advisor, Drexel Hamilton Investment Partners, are not affiliated with Ameristock Corporation, the Ameristock Mutual Fund Inc., or USCF. After the consummation of the reorganization and liquidation, the Ameristock Corporation maintained its non-advisory assets. It is estimated that Mr. Mah will spend approximately 98% of his time on Trust Series and Related Public Fund matters. Mr. Hyland will spend approximately 100% of his time on Trust Series and Related Public Fund matters. To the extent that USCF establishes additional funds, even greater demands will be placed on Messrs. Mah and Hyland, as well as the other officers of USCF and its Board.

SummerHaven is leanly staffed and relies heavily on key personnel to manage advisory activities.

SummerHaven is leanly staffed and relies heavily on key personnel to manage advisory activities. In providing trading advisory services to each Trust Series with respect to its Applicable Index, SummerHaven relies heavily on Messrs. Adam Dunsby, Kurt Nelson and Ashraf Rizvi and Dr. K. Geert Rouwenhorst. Messrs. Dunsby, Nelson and Rizvi, and Dr. Rouwenhorst intend to allocate their time to managing the assets of each Trust Series in a manner that they deem appropriate. If such key personnel of SummerHaven were to leave or be unable to carry out their present responsibilities, it may have an adverse effect on the management of SummerHaven.

The liability of SummerHaven is limited, and the value of the units may be adversely affected if USCF and any Trust Series are required to indemnify SummerHaven.

Under the licensing agreement and advisory agreement between SummerHaven and USCF, neither SummerHaven and its affiliates, nor any of their respective officers, directors, shareholders, members, partners, employees and any person who controls SummerHaven is liable to USCF or any Trust Series absent willful misconduct, gross negligence, bad faith, or material breaches of applicable law or the applicable agreement on the part of SummerHaven. In addition, SummerHaven and its members, directors, officers, shareholders, employees, representatives, agents, attorneys, service providers, successors and assigns have the right to be indemnified, defended and held harmless from and against any and all claims, liabilities, obligations, judgments, causes of action, costs and expenses (including reasonable attorneys’ fees) (collectively, “Losses”) in connection with or arising out of the licensing agreement or advisory agreement, unless such Losses result from any willful misconduct, gross negligence or bad faith on the part of SummerHaven, or a material breach by SummerHaven of applicable law or the applicable agreement. Furthermore, SummerHaven will not be liable to USCF or any Trust Series for any indirect, incidental, special or consequential damages, even if SummerHaven or an authorized representative of SummerHaven has been advised of the possibility of such damages.

55

Accountability levels, position limits, and daily price fluctuation limits set by the Futures Exchanges have the potential to cause a tracking error, which could cause the price of units to substantially vary from the price of the Applicable Index and prevent investors from being able to effectively use a Trust Series as a way to hedge against commodity-related losses or as a way to indirectly invest in commodities.

Designated contract markets such as the NYMEX, COMEX, CME, CBOT, KCBT, ICE Futures and LME 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 a Trust Series is not) may hold, own or control.

In addition to accountability levels and position limits, the Futures Exchanges may also set daily price fluctuation limits on the 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.

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

All of these limits may potentially cause a tracking error between the price of the units and the price of an Applicable Index. This may in turn prevent investors from being able to effectively use a Trust Series as a way to hedge against commodity-related losses or as a way to indirectly invest in commodities. None of the Trust Series has limited the size of its offering and is committed to utilizing substantially all of its proceeds to purchase Futures Contracts and Other Related Investments. If a Trust Series encounters accountability levels, position limits, or price fluctuation limits for Futures Contracts on a particular Futures Exchange, it may then, if permitted under applicable regulatory requirements, purchase Futures Contracts on the other Futures Exchanges that trade listed futures in the relevant commodity. In addition, if a Trust Series exceeds accountability levels on a Futures Exchange and is required by such exchange to reduce its holdings, such reduction could potentially cause a tracking error between the price of the units and the price of the Applicable Index.

The Trust Series, USCF and SummerHaven may have conflicts of interest, which may cause them to favor their own interests to the detriment of unitholders.

The Trust Series, USCF and SummerHaven may have inherent conflicts to the extent USCF and SummerHaven attempt to maintain each Trust Series’ asset size in order to preserve its fee income and this may not always be consistent with such Trust Series’ objective of having the value of its units’ NAV track changes in the value of an Applicable Index.

56

USCF’s and SummerHaven’s officers, directors and employees do not devote their time exclusively to each Trust Series. For example, USCF’s directors, officers and employees act in such capacity for other entities, including the Related Public Funds, that may compete with each Trust Series for their services. They could have a conflict between their responsibilities to each Trust Series and to the Related Public Funds.

USCF has sole current authority to manage the investments and operations of each Trust Series. It has delegated management of each Trust Series’ investments in its Applicable Interests to its trading advisor, SummerHaven. This authority to manage the investments and operations of each Trust Series may allow either USCF or SummerHaven to act in a way that furthers its own interests in conflict with the best interests of investors. Unitholders have very limited voting rights, which will limit the ability to influence matters such as amending the Trust Agreement, changing a Trust Series’ basic investment objective, dissolving a Trust Series, or selling or distributing a Trust Series’ assets.

Unitholders have only very limited voting rights and have the power to replace USCF only under specific circumstances. Unitholders do not participate in the management of a Trust Series and do not control USCF, so they do not have any influence over basic matters that affect each Trust Series. In addition, each Trust Series could terminate at any time and cause the liquidation and potential loss of an investment and could upset the overall maturity and timing of an investment portfolio.

Unitholders have very limited voting rights with respect to each Trust Series’ affairs. Unitholders may elect a replacement sponsor only if USCF resigns voluntarily or loses its corporate charter. Unitholders are not permitted to participate in the management or control of any Trust Series or the conduct of its business. Unitholders must therefore rely upon the duties and judgment of USCF to manage each Trust Series’ affairs.

Each Trust Series may terminate at any time, regardless of whether such Trust Series has incurred losses, subject to the terms of the Trust Agreement. For example, the dissolution or resignation of USCF would cause any Trust Series to terminate unless, within 90 days of the event, unitholders holding units representing at least 66 2/3% of the outstanding units of all of the Trust Series elect to continue the Trust and appoint a successor sponsor. In addition, USCF may terminate any Trust Series if it determines that such Trust Series’ aggregate net assets in relation to its operating expenses make the continued operation of such Trust Series unreasonable or imprudent. However, no level of losses will require USCF to terminate a Trust Series. A Trust Series’ termination would result in the liquidation of its assets and the distribution of the proceeds thereof, first to creditors and then to the unitholders in accordance with their positive book capital account balances, after giving effect to all contributions, distributions and allocations for all periods, and each Trust Series could incur losses in liquidating its assets in connection with a termination. Termination could also negatively affect the overall maturity and timing of an investment portfolio.

USCF may manage a large amount of assets and this could affect a Trust Series’ ability to trade profitably.

Increases in assets under management may affect trading decisions. In general, USCF does not intend to limit the amount of assets of any Trust Series that it may manage. The more assets USCF manages, the more difficult it may be for it to trade profitably because of the difficulty of trading larger positions without adversely affecting prices and performance and of managing risk associated with larger positions.

The liability of USCF and the Trustee are limited, and the value of the units will be adversely affected if any Trust Series is required to indemnify the Trustee or USCF.

Under the Trust Agreement, the Trustee and USCF are not liable, and have the right to be indemnified, for any liability or expense incurred absent gross negligence or willful misconduct on the part of the Trustee or USCF or breach by USCF of the Trust Agreement, as the case may be. As a result, USCF may require the assets of any Trust Series to be sold in order to cover losses or liability suffered by it or by the Trustee. Any sale of that kind would reduce the NAV of such Trust Series and the value of its units.

57

Although the units of each Trust Series are limited liability investments, certain circumstances such as bankruptcy or indemnification of a Trust Series by a unitholder will increase the unitholder’s liability.

The units of each Trust Series are limited liability investments; unitholders may not lose more than the amount that they invest plus any profits recognized on their investment. However, unitholders could be required, as a matter of bankruptcy law, to return to the estate of a Trust Series any distribution they received at a time when such Trust Series was in fact insolvent or in violation of its Trust Agreement. In addition, a number of states do not have “statutory trust” statutes such as the Delaware statutes under which the Trust has been formed in the State of Delaware. It is possible that a court in such state could hold that, due to the absence of any statutory provision to the contrary in such jurisdiction, the unitholders, although entitled under Delaware law to the same limitation on personal liability as stockholders in a private corporation for profit organized under the laws of the State of Delaware, are not so entitled in such state. Finally, in the event the Trust or any Trust Series is made a party to any claim, dispute, demand or litigation or otherwise incurs any liability or expense as a result of or in connection with any unitholder’s (or assignee’s) obligations or liabilities unrelated to the business of the Trust or such Trust Series, as applicable, such unitholder (or assignees cumulatively) is required under the Trust Agreement to indemnify the Trust or such Trust Series, as applicable, for all such liability and expense incurred, including attorneys’ and accountants’ fees.

Investors cannot be assured of USCF’s continued services, and discontinuance may be detrimental to a Trust Series.

Investors cannot be assured that USCF will be willing or able to continue to service each Trust Series for any length of time. USCF was formed for the purpose of sponsoring each Trust Series and other commodity pools, and has limited financial resources and no significant source of income apart from its management fees from the commodity pools it operates to support its continued service for each Trust Series. If USCF discontinues its activities on behalf of a Trust Series, such Trust Series may be adversely affected. If USCF’s registration with the CFTC or membership in the NFA were revoked or suspended, USCF would no longer be able to provide services to any Trust Series.

Investors cannot be assured of the continuation of the agreement between SummerHaven and USCF for use of an Applicable Index, and discontinuance of an Applicable Index may be detrimental to a Trust Series.

Investors cannot be assured that the agreement between SummerHaven and USCF for use of an Applicable Index will continue for any length of time. Should the agreement between SummerHaven and USCF for use of an Applicable Index be terminated, USCF will be required to find a replacement index, which may have an adverse affect on a Trust Series.

Investors cannot be assured of SummerHaven’s continued services, and discontinuance may be detrimental to a Trust Series.

Investors cannot be assured that SummerHaven will be willing or able to continue to service each Trust Series for any length of time. SummerHaven was formed for the purpose of providing investment advisory services, and provides these services to each Trust Series on a contractual basis pursuant to a licensing agreement and an advisory agreement. If SummerHaven discontinues its activities on behalf of any Trust Series, such Trust Series may be adversely affected. If SummerHaven’s registration with the CFTC or membership in the NFA were revoked or suspended, SummerHaven would no longer be able to provide services to any Trust Series.

As a unitholder, investors will not have the rights enjoyed by investors in certain other types of entities.

As interests in separate series of a Delaware statutory trust, the units do not involve the rights normally associated with the ownership of common stock of a corporation. For example, the units have limited voting and distribution rights (for example, unitholders do not have the right to elect directors and generally will not receive regular distributions of the net income and capital gains earned by a Trust Series). Each Trust Series is also not subject to certain investor protection provisions of the Sarbanes Oxley Act of 2002 and certain NYSE Arca governance rules (for example, audit committee requirements). In addition, the Trust Agreement limits the rights of unitholders to bring derivative actions.

All of the Trust Series are series of the Trust and, as a result, a court could potentially conclude that the assets and liabilities of one Trust Series are not segregated from those of another Trust Series, thereby potentially exposing assets in one Trust Series to the liabilities of another Trust Series.

Each Trust Series is a series of a Delaware statutory trust and not itself a separate legal entity. The Delaware Statutory Trust Act provides that if certain provisions are included in the formation and governing documents of a statutory trust organized in series and if separate and distinct records are maintained for any series and the assets associated with that series are held in separate and distinct records and are accounted for in such separate and distinct records separately from the other assets of the statutory trust, or any series thereof, then the debts, liabilities, obligations and expenses incurred by a particular series are enforceable against the assets of such series only, and not against the assets of the statutory trust generally or any other series thereof. Conversely, none of the debts, liabilities, obligations and expenses incurred with respect to any other series thereof shall be enforceable against the assets of such series. USCF is not aware of any court case that has interpreted this Inter-Series Limitation on Liability or provided any guidance as to what is required for compliance. USCF intends to maintain separate and distinct records for each Trust Series and account for each Trust Series separately from any other Trust Series, but it is possible a court could conclude that the methods used do not satisfy the Delaware Statutory Trust Act, which would potentially expose assets in one series to the liabilities of another Trust Series.

58

USCF and the Trustee are not obligated to prosecute any action, suit or other proceeding in respect of any Trust Series property.

Neither USCF nor the Trustee is obligated to, although each may in its respective discretion, prosecute any action, suit or other proceeding in respect of any Trust Series property. The Trust Agreement does not confer upon unitholders the right to prosecute any such action, suit or other proceeding.

The Trust Series do not expect to make cash distributions.

The Trust Series have not previously made any cash distributions and intend to re-invest any income and realized gains of each Trust Series in additional Applicable Interests rather than distributing cash to unitholders. Therefore, unlike mutual funds, commodity pools or other investment pools that generally distribute income and gains to their investors, none of the Trust Series generally expects to distribute cash to unitholders. An investor should not invest in a Trust Series if it will need cash distributions from such Trust Series to pay taxes on its share of income and gains of such Trust Series, if any, or for any other reason. Although each Trust Series 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 Applicable Interests and investors adversely react to being taxed on such income without receiving distributions that could be used to pay such tax. Cash distributions may be made in these and similar instances.

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

Each Trust Series is obligated to pay USCF a management fee based on its average daily net assets, over-the-counter spreads and various other expenses of its ongoing operations (e.g., fees of the Trustee). These fees and expenses must be paid in all events, regardless of whether a Trust Series’ activities are profitable. Accordingly, each Trust Series must realize trading gains sufficient to cover these fees and expenses before it can earn any profit.

If offerings of the units do not raise sufficient funds to make a Trust Series’ future operations viable, a Trust Series may be forced to terminate and investors may lose all or part of their investment.

Prior to the offering of units, all of a Trust Series’ expenses are funded by USCF. These payments by USCF are designed to allow a Trust Series the ability to commence the public offering of its units. If USCF and a Trust Series are unable to raise sufficient funds so that such Trust Series’ expenses are reasonable in relation to its NAV, such Trust Series may be forced to terminate and investors may lose all or part of their investment.

A Trust Series may incur higher fees and expenses upon renewing existing or entering into new contractual relationships.

The arrangements between SummerHaven, clearing brokers and counterparties on the one hand and a Trust Series on the other generally are terminable by SummerHaven, the clearing brokers or counterparty upon notice to such Trust Series. Upon termination, USCF may be required to renegotiate or make other arrangements for obtaining similar services if a Trust Series intends to continue trading in Futures Contracts or Other Related Investments under the advisement of SummerHaven. The services of SummerHaven or any clearing broker or counterparty may not be available, or even if available, these services may not be available on the terms as favorable as those of the expired or terminated arrangements.

An unanticipated number of redemption requests during a short period of time could have an adverse effect on the per unit NAV of a Trust Series.

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

59

The financial markets are currently in a slow period of recovery and the financial markets are still relatively fragile.

Since 2008, the financial markets have experienced very difficult conditions and volatility as well as significant adverse trends. The conditions in these markets have resulted in a decrease in availability of corporate credit and liquidity and have led indirectly to the insolvency, closure or acquisition of a number of major financial institutions and have contributed to further consolidation within the financial services industry. In addition, the Administration and Congress have periodically been reaching impasses in passing a fiscal budget which could create long-term concerns regarding the credit of the United States and interest earned, as well as the United States Government’s ability to pay its obligations to holders of Treasuries. If low interest rates on Treasuries continues or if a Trust Series is not able to redeem its investments in Treasuries prior to maturity and the U.S. Government cannot pay its obligations, a Trust Series would be negatively impacted. In addition, a Trust Series might also be negatively impacted by its use of money market mutual funds to the extent those funds might themselves be using Treasuries. Although the financial markets saw signs of recovery beginning in late 2010 and 2011, economic growth in 2012 was slow and the financial markets are still fragile. A poor financial recovery could adversely affect the financial condition and results of operations of a Trust Series’ service providers and Authorized Purchasers, which would impact the ability of USCF to achieve such Trust Series’ investment objective.

The liquidity of the units may be affected by the withdrawal from participation of Authorized Purchasers, which could adversely affect the market price of the units.

In the event that one or more Authorized Purchasers that have substantial interests in the units withdraw from participation, the liquidity of the units will likely decrease, which could adversely affect the market price of the units and result in incurring a loss on an investment.

Investors may be adversely affected by redemption orders that are subject to postponement, suspension or rejection under certain circumstances.

The Trust may, in its discretion, suspend the right to redeem units of any Trust Series or postpone the redemption settlement date: (1) for any period during which an a Futures Exchange is closed other than customary weekend or holiday closing, or trading is suspended or restricted; (2) for any period during which an emergency exists as a result of which delivery, disposal or evaluation of a Trust Series’ assets is not reasonably practicable; or (3) for such other period as USCF determines to be necessary for the protection of unitholders. In addition, the Trust will reject a redemption order if the order is not in proper form as described in the agreement with the Authorized Purchaser or if the fulfillment of the order, in the opinion of its counsel, might be unlawful. Any such postponement, suspension or rejection could adversely affect a redeeming unitholder. For example, the resulting delay may adversely affect the value of the unitholder’s redemption proceeds if the NAV of a Trust Series declines during the period of delay. The Trust Agreement provides that USCF and its designees will not be liable for any loss or damage that may result from any such suspension or postponement.

The failure, bankruptcy or default of a clearing broker or the Custodian could result in substantial losses for a Trust Series and could impair a Trust Series’ ability to execute trades.

Under CFTC regulations, a clearing broker with respect to a Trust Series’ exchange-traded Applicable Interests must maintain 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 a Trust Series, 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. However, customers could potentially lose all funds on deposit with the clearing broker even if such funds are properly segregated. A Trust Series also may 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 Applicable Interests are traded.

In addition, to the extent a Trust Series’ clearing broker is required to post such Trust Series’ 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 a Trust Series’ 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 such Trust Series’ and any other non-defaulting customers of the clearing broker to satisfy the obligations of the clearing broker.

60

From time to time, the 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 a Trust Series’ trades.

In addition, the majority of each Trust Series’ assets are held in short-term Treasuries, cash and/or cash equivalents with the Custodian. The insolvency of the Custodian could result in a complete loss of a Trust Series’ assets held by that Custodian, which, at any given time, would likely comprise a substantial portion of such Trust Series’ 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.

Third parties may utilize USCF’s intellectual property or technology (which includes intellectual property or technology that USCF licenses from SummerHaven), including the use of its patents, business methods, trademarks and trading program software, without permission. USCF is in the process of registering its trademarks. None of the Trust Series currently has any proprietary software. However, if it obtains proprietary software in the future, then any unauthorized use of a Trust Series’ proprietary software and other technology could also adversely affect its competitive advantage. A Trust Series may not have adequate resources to implement procedures for monitoring unauthorized uses of its trademarks, proprietary software and other technology. Also, third parties may independently develop 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 a Trust Series, or require it to change its proprietary software and other technology or enter into royalty or licensing agreements.

The success of each Trust Series depends on the ability of SummerHaven to accurately implement USCF’s trading strategies, and any failure to do so could subject a Trust Series to losses on such transactions.

USCF’s trading strategy for each Trust Series, as developed by SummerHaven, is quantitative in nature and it is possible that USCF or SummerHaven will make errors in its implementation. The execution of the quantitative strategy is subject to human error, such as incorrect inputs into USCF’s or SummerHaven’s computer systems and incorrect information provided to a Trust Series’ clearing brokers. In addition, each Trust Series relies on USCF to properly operate and maintain its computer and communication systems. Extraordinary transaction volume, hardware or software failure, power or telecommunications failure, a natural disaster or other catastrophe could cause the computer systems to operate at an unacceptably slow speed or even fail. Any significant degradation or failure of the systems that USCF uses to gather and analyze information, enter orders, process data, monitor risk levels and otherwise engage in trading activities may result in substantial losses on transactions, liability to other parties, lost profit opportunities, damages to USCF’s and a Trust Series’ reputations, increased operational expenses and diversion of technical resources. Any failure, inaccuracy or delay in implementing any of the formulas or systems, including implementing upgrades and compatibility with the computer systems of third parties, and executing a Trust Series’ transactions could affect its ability to achieve its investment objective. It could also result in decisions to undertake transactions based on inaccurate or incomplete information. This could cause substantial losses on transactions.

The occurrence of a terrorist attack, or the outbreak, continuation or expansion of war or other hostilities could disrupt one or more Trust Series’ trading activity and materially affect such Trust Series’ profitability.

The operations of each Trust Series, the exchange, brokers and counterparties with which each Trust Series does business, and the markets in which each Trust Series does business could be severely disrupted in the event of a major terrorist attack or the outbreak, continuation or expansion of war or other hostilities. Global anti-terrorism initiatives, political unrest in the Middle East and Southeast Asia, as well as political hostility toward the United States, continue to fuel this concern.

61

Risk of Leverage and Volatility

If USCF causes or permits a Trust Series to become leveraged, investors could lose all or substantially all of their investment if such Trust Series’ trading positions suddenly turn unprofitable.

Commodity pools’ trading positions in futures contracts or other commodity interests 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. This feature permits commodity pools to “leverage” their assets by purchasing or selling futures contracts (or other commodity interests) with an aggregate face amount in excess of the commodity pool’s assets. While this leverage can increase a pool’s profits, relatively small adverse movements in the price of the pool’s commodity interests can cause significant losses to the pool. While USCF has not and does not currently intend to leverage the assets of any Trust Series, it is not prohibited from doing so under the Trust Agreement. If USCF were to cause or permit a Trust Series to become leveraged, investors could lose all or substantially all of their investment if such Trust Series’ trading positions suddenly turn unprofitable.

Fewer representative commodities may result in greater Applicable Index volatility.

Each Applicable Index is concentrated in terms of the number of commodities represented. Investors should be aware that other commodities indices are more diversified in terms of both the number and variety of commodities included. Concentration in fewer commodities may result in a greater degree of volatility in an Applicable Index and the NAV of a Trust Series which tracks an Applicable Index under specific market conditions and over time.

Lengthy and substantial peak-to-valley declines in the value of an Applicable Index may lead to even greater declines in the NAV of a Trust Series.

Because it is expected that each Trust Series’ performance will relate to the performance of its Applicable Index, each Trust Series will suffer a decline in value during a period that its Applicable Index suffers such a decline, and in turn, the value of the units will decline. It is possible or even likely that redemptions of Redemption Baskets will exceed purchases of Creation Baskets during periods in which a Trust Series’ units are declining in value. While redemptions will not directly cause the value of the units to decline, redemptions will accentuate the reduction in a Trust Series’ NAV that is caused by losses from such Trust Series’ positions, potentially resulting in an increase in such Trust Series’ expenses as a percentage of NAV. Furthermore, redemptions may increase transaction costs by requiring the sale of Applicable Interests and Treasuries to meet redemption requests.

Each Trust Series’ exposure to the applicable commodities markets may subject investors to greater volatility than investments in traditional securities.

Each Trust Series’ exposure to the applicable commodities markets may subject investors to greater volatility than investments in traditional securities. The value of Applicable Interests may be affected by changes in the overall commodity markets or commodity indices, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments.

Over-the-Counter Contract Risk

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

A portion of each Trust Series’ assets may be used to trade over-the-counter Applicable Interests, such as forward contracts or swap or spot contracts. Currently, 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 and that prior to the passage of the Dodd-Frank Act had been essentially unregulated by the CFTC. The markets for over-the-counter contracts have relied upon the integrity of market participants in lieu of the additional regulation imposed by the CFTC on participants in the futures markets. To date, the forward markets have been largely unregulated, forward contracts have been executed bi-laterally and, in general, forward contracts have not been cleared or guaranteed by a third party. On November 16, 2012, the Secretary of the Treasury issued a final determination that 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 derivatives, such as foreign exchange options, certain currency swaps and non-deliverable forwards. While the Dodd-Frank Act and certain regulations adopted thereunder 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 a Trust Series in certain circumstances to significant losses in the event of trading abuses or financial failure by participants. See “Item 1. Business – Regulation” for a discussion of how the over-the-counter market will be subject to much more extensive CFTC oversight and regulation after the implementation of the Dodd-Frank Act.

62

Each Trust Series will be subject to credit risk with respect to counterparties to over-the-counter contracts entered into by such Trust Series.

Each Trust Series 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 a Trust Series, in which case such Trust Series could suffer significant losses on these contracts.

If a counterparty becomes bankrupt or otherwise fails to perform its obligations due to financial difficulties, a Trust Series may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. During any such period, such Trust Series may have difficulty in determining the value of its contracts with the counterparty, which in turn could result in the overstatement or understatement of such Trust Series’ NAV. Such Trust Series may eventually obtain only limited recovery or no recovery in such circumstances.

Each Trust Series may be subject to liquidity risk with respect to its over-the-counter transactions.

Over-the-counter contracts are less marketable 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 a Trust Series’ 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.

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.

The Dodd-Frank Act requires the CFTC and SEC to establish “both initial and variation margin requirements on all swaps that are not cleared by a registered clearing organization” (i.e., uncleared swaps). In addition, the Dodd-Frank Act provides parties who post initial margin to a swap dealer or major swap participant with a statutory right to insist that such margin be held in a segregated account with an independent custodian. At this time, the CFTC has proposed a rule addressing this statutory right of certain market participants but has not yet implemented any final rules. On November 16, 2012, the Secretary of the Treasury issued a final determination that 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).

Risk of Trading in International Markets

Trading in international markets would expose a Trust Series to credit and regulatory risk.

The significant portion of the Applicable Benchmark Component Futures Contracts purchased by a Trust Series are traded on a United States futures exchange. However, a portion of the trades made by a Trust Series 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. The CFTC, NFA and the domestic exchanges have little, if any, regulatory authority over the activities of any foreign boards of trade or exchanges, including the execution, delivery and clearing of transactions, and have little, if any, power to compel enforcement of the rules of a foreign board of trade or exchange or of any applicable non-U.S. laws. Similarly, the rights of market participants, such as a Trust Series, in the event of the insolvency or bankruptcy of a non-U.S. market or broker are also likely to be more limited than in the case of U.S. markets or brokers. As a result, in these markets, a Trust Series has less legal and regulatory protection than it does when it trades domestically.

63

In some of these non-U.S. markets, the performance on a futures contract is the responsibility of the counterparty and is not backed by an exchange or clearing corporation and therefore exposes a Trust Series to credit risk. 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.

International trading activities subject a Trust Series to foreign exchange risk.

The price of any non-U.S. commodity interest and, therefore, the potential profit and loss on such investment, may be affected by any variance in the foreign exchange rate between the time the order is placed and the time it is liquidated, offset or exercised. As a result, changes in the value of the local currency relative to the U.S. dollar may cause losses to a Trust Series even if the contract traded is profitable.

A Trust Series’ international trading could expose it to losses resulting from non-U.S. exchanges that are less developed or less reliable than United States exchanges.

Some non-U.S. exchanges may be in a more developmental stage so that prior price histories may not be indicative of current price dynamics. In addition, a Trust Series may not have the same access to certain positions on foreign trading exchanges as do local traders, and the historical market data on which USCF bases its strategies may not be as reliable or accessible as it is for U.S. exchanges.

Tax Risk

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

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 units. 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 a Trust Series’ 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 units 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 units.

Due to the application of the assumptions and conventions applied by a Trust Series in making allocations for tax purposes and other factors, an investor’s allocable share of a Trust Series’ income, gain, deduction or loss may be different than its economic profit or loss from its units 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 units could be reallocated if the Internal Revenue Service does not accept the assumptions and conventions applied by a Trust Series in allocating those items, with potential adverse consequences for an investor.

The U.S. tax rules pertaining to partnerships, which apply to each Trust Series, generally were not written for, and in some respects are difficult to apply to, entities whose interests are publicly traded. The Trust applies certain assumptions and conventions in an attempt to comply with the applicable rules and to report taxable income, gains, deductions, losses and credits in a manner that generally corresponds to unitholders’ interests in a Trust Series. These assumptions and conventions may not fully comply with all aspects of the Internal Revenue Code (the “Code”) and applicable Treasury Regulations, however, and they could be successfully challenged by the IRS. If so, the Trust could be required to reallocate items of income, gain, deduction, loss or credit for tax purposes in a manner that adversely affects investors, in which case investors may be required to file an amended tax return and to pay additional taxes plus deficiency interest.

64

A Trust Series could be treated as a corporation for federal income tax purposes, which may substantially reduce the value of the units.

In order to avoid being taxable as corporation, at least 90 percent (90%) of each Trust Series’ annual gross income must consist of “qualifying income” as defined in the Code. Although USCF has satisfied and anticipates that it will continue to satisfy the “qualifying income” requirement for all of its taxable years, that result cannot be assured. None of the Trust Series has 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 any Trust Series 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 unitholders, such Trust Series’ 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 units, any distributions would be taxable to unitholders as dividend income. Taxation of any Trust Series as a corporation could materially reduce the after-tax return on an investment in units and could substantially reduce the value of the units.

Each Trust Series is organized as a Delaware statutory trust, but each Trust Series is taxed as a limited partnership in accordance with the provisions of the Trust Agreement and applicable state law, and therefore, each Trust Series has a more complex tax treatment than traditional mutual funds.

Each Trust Series is organized as a Delaware statutory trust, but each Trust Series is taxed as a limited partnership in accordance with the provisions of the Trust Agreement and applicable state law. No U.S. federal income tax is paid by each Trust Series on its income. Instead, each Trust Series will furnish unitholders each year with tax information on IRS Schedule K-1 (Form 1065) and each U.S. unitholder is required to report on its U.S. federal income tax return its allocable share of the income, gain, loss and deduction of each Trust Series. This must be reported without regard to the amount (if any) of cash or property the unitholder receives as a distribution from an applicable Trust Series during the taxable year. A unitholder, therefore, may be allocated income or gain by a Trust Series 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.

Risks Specific to USCI, CPER, USAG and USMI

Risks Specific to USCI

The Commodity Index reflects commodities in the energy, precious metals, industrial metals, grains, softs and livestock sectors. A change in price of any of the commodities in these sectors will have a significant effect on the level of the Commodity Index and the value of USCI’s units, which could have a material adverse effect on an investment.

For December 2012, the Commodity Index reflected commodities in six commodity sectors: energy (representing approximately 26.69% of the Commodity Index), precious metals (representing approximately 7.01% of the Commodity Index), industrial metals (representing approximately 23.82% of the Commodity Index), grains (representing approximately 28.35% of the Commodity Index), softs (representing approximately 6.97% of the Commodity Index), and livestock (representing approximately 7.16% of the Commodity Index). In addition to the factors affecting commodities generally that are described above, commodities in each sector are subject to specific risks in light of the nature of the sector.

Some specific risks of each sector are described below:

Energy commodities

The prices of energy commodities (e.g., crude oil, natural gas, heating oil, etc.), in particular, WTI crude oil, Brent crude oil and natural gas, are subject to national and global political events such as: governmental regulation and intervention in energy markets; imposition of price controls; increases or restriction of production levels by significant oil producing countries and coordination of production levels by those countries; and disruptions in oil producing areas. The prices of energy commodities have had significant price swings in recent years. Disruptions in energy producing areas, including as a result of war, armed conflict, terrorism, embargoes, social unrest and political instability, can cause significant volatility in the Commodity Index. Energy commodity production frequently occurs in politically unstable regions of the world, including Africa, the Middle East, Asia and South America.

65

Additionally, because a significant amount of oil is produced by a limited number of countries, many of who are members of the Organization of Petroleum Exporting Countries, or OPEC, actions of OPEC can influence the price of the energy sector and consequently the value of USCI units. In the past, OPEC has decided to limit production, which has created upward price pressure. Subsequent decisions by OPEC to increase production could lead to oversupply and subsequent drops in energy prices. Prices for the commodities in the energy sector have also been significantly affected in recent years by weather and natural disasters, such as hurricanes, affecting production, refining and transportation facilities. For example, the U.S. General Accounting Office has estimated that following Hurricanes Katrina and Rita in Fall 2005, natural gas prices spiked to prices nearly seven times the prices common during the late 1990s.

Other factors also influence supply and demand of the commodities in the energy sector. Changes in levels of global industrial activity influence demand for the commodities in the energy sector. Market expectations about events that may influence supply and demand also have an impact on the price of commodities, including expectations about the ability to develop oil and natural gas reserves. Seasonal changes in demand (such as the U.S. summer “driving season” and the winter “heating season”) also influence pricing of energy commodities.

Precious metal commodities

The prices of precious metals (e.g., gold, silver, platinum) may be influenced by macroeconomic conditions, including confidence in the global monetary system and the relative strength of various currencies, as well as demand in the industrial and jewelry sectors. Political events also influence the price of precious metals. Prices are influenced by supplies of precious metals, which may be affected by sales by central banks and government agencies that hold large amounts of these metals, particularly gold. Significant changes in the value of the precious metals sector may lead to volatility in the value of USCI units and/or significant losses to unitholders.

Industrial metal commodities

The prices of the commodities comprising the industrial metals portion of the Commodity Index (e.g., zinc, nickel, aluminum, copper, etc.) are subject to a number of factors that can cause price fluctuations, including: changes in the level of industrial activity using these metals (including the availability of man-made substitutes); disruptions in the mining, storage, or refining of these metals; adjustments to inventory; variations in production costs, including storage, labor and energy costs; regulatory compliance costs, including environmental regulations; and changes in government and consumer demand.

These factors can lead to price volatility for industrial metals commodities that, in turn, may lead to corresponding volatility in the value of USCI’s units. For example, with respect to aluminum, the level of activity in the automotive, packaging and construction industries has significantly influenced demand because of the use of aluminum in these industries. Disruptions in the supply chain, which result in upward price pressure, also have an impact on the industrial metals sector and may have a corresponding impact on the value of the units. For example, the industrial metals included in this sector are often mined in locations that are subject to disruption as a result of political instability, armed conflict, terrorism and labor unrest, among other factors. Production costs, particularly the cost of energy used in production, and costs associated with regulatory compliance, including environmental regulation costs, can also inflate the price of the underlying commodities in the industrial metals sector. These increases may not be sustainable. Any one or all of these sector-specific factors may result in volatility in the industrial metals sector, which could lead to corresponding volatility in the value of the units and/or significant losses to unitholders.

Grains and Softs product commodities

The commodities comprising the grains (e.g., wheat, corn, soybeans, etc.) and softs (e.g., sugar, cotton, coffee, cocoa) products sectors of the Commodity Index are subject to a number of factors that can cause price fluctuations, including: weather conditions, such as floods, drought and freezing conditions; changes in government policies (including subsidies) and trade agreements; planting decisions; and changes in demand for grains and softs.

These factors can lead to price volatility for grains and softs commodities that, in turn, may lead to corresponding volatility in the value of USCI units. Weather conditions can lead to tightened supply and price increases, which may not be sustainable. Government policies and trade agreements can influence both supply and demand. Grains and softs products are also subject to the planting decisions of farmers, which can be influenced both by government policies as well as changing demands for their products.

66

Livestock commodities

The commodities comprising the livestock sector of the Commodity Index (e.g., live cattle, lean hogs, feeder cattle) are subject to a number of factors that can cause price fluctuations, including: weather conditions, such as floods, drought and freezing conditions; disease and famine; changes in government policies (including subsidies); and changes in demand for livestock. These factors can lead to price volatility for livestock commodities that, in turn, may lead to corresponding volatility in the value of USCI units.

Risks Specific to CPER

Changes in the valuation of the Copper Index may adversely affect the value of CPER’s units.

SummerHaven Indexing may modify the method for determining the weighting of the Copper Index and for calculating its value in order to ensure that the Copper Index represents a measure of the performance over time of the market for the investment returns of a portfolio of copper futures contracts. Such changes could adversely affect the value of CPER’s units. For more information about the methodology for determining the compositions and weighting of the Copper Index, see “Item 1. Business—What is the Copper Index?” in this annual report on Form 10-K.

The Copper Index is currently composed exclusively of copper futures contracts traded on regulated futures exchanges. The Copper Index may in the future include contracts traded in the OTC market or on trading facilities that are subject to lesser degrees of regulation or, in some cases, no substantive regulation. If this were to occur, increased investment by CPER in the OTC market or on alternative trading facilities may become necessary in order for CPER to track the Copper Index. Many electronic trading facilities have only recently initiated trading and do not have significant trading histories. As a result, the trading of contracts on such facilities and the inclusion of such contracts in the Copper Index may be subject to risks not presented by most exchange-traded futures contracts, including risks related to the liquidity and price histories of relevant contracts.

Only one commodity may result in greater Copper Index volatility.

The Copper Index is concentrated in terms of the representing just one commodity. Investors should be aware that other commodities indices are more diversified in terms of both the number and variety of commodities included. Concentration in fewer commodities or a single commodity may result in a greater degree of volatility in the Copper Index and the per unit NAV of CPER which tracks the Copper Index under specific market conditions and over time.

The Copper Index reflects an investment in a collateralized copper futures portfolio. A change in the price of copper will have a significant effect on the level of the Copper Index and the value of CPER’s units, which could have a material adverse effect on an investment.

The Copper Index reflects a commodity in the industrial metal commodity sector and is subject to a number of specific risks. The price of copper is subject to a number of factors that can cause price fluctuations, including: changes in the level of industrial activity using copper (including the availability of man-made substitutes); disruptions in the mining, storage, or refining of copper; adjustments to inventory; variations in production costs, including storage, labor and energy costs; regulatory compliance costs, including environmental regulations; and changes in government and consumer demand.

These factors can lead to price volatility for copper that, in turn, may lead to corresponding volatility in the value of CPER’s units. Disruptions in the supply chain, which result in upward price pressure, also have an impact on copper and may have a corresponding impact on the value of the units. For example, copper is often mined in locations that are subject to disruption as a result of political instability, armed conflict, terrorism and labor unrest, among other factors. Production costs, particularly the cost of energy used in production, and costs associated with regulatory compliance, including environmental regulation costs, can also inflate the price of copper. These increases may not be sustainable. Any one or all of these sector-specific factors may result in volatility in copper, which could lead to corresponding volatility in the value of the units and/or significant losses to unitholders.

Risks Specific to USAG

USAG commenced operations on April 13, 2012, so there is less than one year of performance history to serve as a basis for investors to evaluate an investment in USAG.

USAG began operations on April 13, 2012 and therefore, has less than a one-year operating history. Therefore, investors do not have the benefit of reviewing the past performance of USAG as a basis to evaluate an investment in USAG. USCF’s current experience involves managing the Related Public Funds, most of which seek to track a single commodity benchmark futures contract. USCF’s results with the Related Public Funds may not be directly applicable to USAG because USAG seeks to track the Agriculture Index which is comprised of 14 Benchmark Component Agriculture Futures Contracts and is rebalanced monthly.

Changes in the valuation of the Agriculture Index may adversely affect the value of USAG’s units.

SummerHaven Indexing may modify the method for determining the weighting of the Agriculture Index and for calculating its value in order to ensure that the Agriculture Index represents a measure of the performance over time of the markets for the underlying agricultural commodities. Such changes could adversely affect the value of USAG’s units. For more information about the methodology for determining the compositions and weighting of the Agriculture Index, see “Item 1. Business—What is the Agriculture Index?” in this annual report on Form 10-K.

The Agriculture Index is currently composed exclusively of agriculture futures contracts traded on regulated futures exchanges. The Agriculture Index may in the future include contracts traded in the over-the-counter market or on trading facilities that are subject to lesser degrees of regulation or, in some cases, no substantive regulation. If this were to occur, increased investment by USAG in the over-the-counter market or on alternative trading facilities may become necessary in order for USAG to track the Agriculture Index. Many electronic trading facilities have only recently initiated trading and do not have significant trading histories. As a result, the trading of contracts on such facilities and the inclusion of such contracts in the Agriculture Index may be subject to risks not presented by most exchange-traded futures contracts, including risks related to the liquidity and price histories of relevant contracts.

Fewer representative commodities may result in greater Agriculture Index volatility.

The Agriculture Index is concentrated in terms of the number of commodities represented. Investors should be aware that other commodities indices are more diversified in terms of both the number and variety of commodities included. Concentration in fewer commodities may result in a greater degree of volatility in the Agriculture Index and the NAV of USAG which tracks the Agriculture Index under specific market conditions and over time.

The Agriculture Index reflects commodities in the grains, softs and livestock sectors. A change in price of any of the commodities in these sectors will have a significant effect on the level of the Agriculture Index and the value of USAG’s units, which could have a material adverse effect on an investment.

As of December 31, 2012, the weighting of the Benchmark Component Agriculture Futures Contracts that comprise the Agriculture Index is approximately 56.93% grains, 25.25% softs and 17.83% livestock. In addition to the factors affecting commodities generally that are described above, commodities in each sector are subject to specific risks in light of the nature of the sector.

Some specific risks of each sector are described below:

Grains and Softs product commodities

The commodities comprising the grains (e.g. , wheat, corn, soybeans, etc.) and softs (e.g., sugar, cotton, coffee, cocoa) products sectors of the Agriculture Index are subject to a number of factors that can cause price fluctuations, including: weather conditions, such as floods, drought and freezing conditions; changes in government policies (including subsidies) and trade agreements; planting decisions; and changes in demand for grains and softs.

These factors can lead to price volatility for grains and softs commodities that, in turn, may lead to corresponding volatility in the value of units. Weather conditions can lead to tightened supply and price increases, which may not be sustainable. Government policies and trade agreements can influence both supply and demand. Grains and softs products are also subject to the planting decisions of farmers, which can be influenced both by government policies as well as changing demands for their products.

68

Livestock commodities

The commodities comprising the livestock sector of the Agriculture Index (e.g., live cattle, lean hogs, feeder cattle) are subject to a number of factors that can cause price fluctuations, including: weather conditions, such as floods, drought and freezing conditions; disease and famine; changes in government policies (including subsidies); and changes in demand for livestock. These factors can lead to price volatility for livestock commodities that, in turn, may lead to corresponding volatility in the value of USAG units.

Risks Specific to USMI

USMI commenced operations on June 19, 2012, so there is less than one year of performance history to serve as a basis for an investor to evaluate an investment in USMI.

USMI commenced operations on June 19, 2012 and therefore, has less than a one-year operating history. Therefore, an investor does not have the benefit of reviewing the past performance of USMI as a basis to evaluate an investment in USMI. Much of USCF’s experience involves managing the Related Public Funds, most of which seek to track a single commodity benchmark futures contract. USCF’s results with these funds may not be directly applicable to USMI because USMI seeks to track the Metals Index which is comprised of ten Benchmark Metals Futures Contracts and is rebalanced monthly.

Changes in the valuation of the Metals Index may adversely affect the value of USMI’s Units.

SummerHaven Indexing may modify the method for determining the weighting of the Metals Index and for calculating its value in order to ensure that the Metals Index represents a measure of the performance over time of the markets for the investment returns of a portfolio of metals futures contracts. Such changes could adversely affect the value of USMI’s Units. For more information about the methodology for determining the compositions and weighting of the Metals Index, see “Item 1. Business—What is the Metals Index?” in this annual report on Form 10-K.

The Metals Index is currently composed exclusively of metals futures contracts traded on regulated futures exchanges. The Metals Index may in the future include contracts traded in the OTC market or on trading facilities that are subject to lesser degrees of regulation or, in some cases, no substantive regulation. If this were to occur, increased investment by USMI in the OTC market or on alternative trading facilities may become necessary in order for USMI to track the Metals Index. Many electronic trading facilities have only recently initiated trading and do not have significant trading histories. As a result, the trading of contracts on such facilities and the inclusion of such contracts in the Metals Index may be subject to risks not presented by most exchange-traded futures contracts, including risks related to the liquidity and price histories of relevant contracts.

Fewer representative commodities may result in greater Metals Index volatility.

The Metals Index is concentrated in terms of the numbers of commodities represented. Investors should be aware that other commodities indices are more diversified in terms of both the number and variety of commodities included. Concentration in fewer commodities or a single commodity may result in a greater degree of volatility in the Metals Index and the NAV of USMI which tracks the Metals Index under specific market conditions and over time.

The Metals Index reflects commodities in the precious metals and industrial metals sectors. A change in price of any of the commodities in these sectors will have a significant effect on the level of the Metals Index and the value of USMI’s Units, which could have a material adverse effect on an investment.

As of December 31, 2012, the weighting of the Benchmark Component Metals Futures Contracts that comprise the Metals Index is approximately 35.61% precious metals and approximately 64.39% industrial metals. In addition to the factors affecting commodities generally that are described in the Form 10-K, commodities in each sector are subject to specific risks in light of the nature of the sector.

Some specific risks of these sectors are described below:

Precious metal commodities

The prices of precious metals (e.g. gold, silver, platinum) may be influenced by macroeconomic conditions, including confidence in the global monetary system and the relative strength of various currencies, as well as demand in the industrial and jewelry sectors. Political events also influence the price of precious metals. Prices are influenced by supplies of precious metals, which may be affected by sales by central banks and government agencies that hold large amounts of these metals, particularly gold. Significant changes in the value of the precious metals sector may lead to volatility in the value of USMI’s units and/or significant losses to unitholders.

69

Industrial metal commodities

The prices of the commodities comprising the industrial metals portion of the Metals Index (e.g. zinc, nickel, aluminum, copper, etc.) are subject to a number of factors that can cause price fluctuations, including: changes in the level of industrial activity using these metals (including the availability of man-made substitutes); disruptions in the mining, storage, or refining of these metals; adjustments to inventory; variations in production costs, including storage, labor and energy costs; regulatory compliance costs, including environmental regulations; and changes in government and consumer demand.

These factors can lead to price volatility for industrial metals commodities that, in turn, may lead to corresponding volatility in the value of USMI units. For example, with respect to aluminum, the level of activity in the automotive, packaging and construction industries has significantly influenced demand because of the use of aluminum in these industries. Disruptions in the supply chain, which result in upward price pressure, also have an impact on the industrial metals sector and may have a corresponding impact on the value of the Units. For example, the industrial metals included in this sector are often mined in locations that are subject to disruption as a result of political instability, armed conflict, terrorism and labor unrest, among other factors. Production costs, particularly the cost of energy used in production, and costs associated with regulatory compliance, including environmental regulation costs, can also inflate the price of the underlying commodities in the industrial metals sector. These increases may not be sustainable. Any one or all of these sector-specific factors may result in volatility in the industrial metals sector, which could lead to corresponding volatility in the value of the units and/or significant losses to unitholders.

These factors can lead to price volatility for copper that, in turn, may lead to corresponding volatility in the value of USMI’s units. Disruptions in the supply chain, which result in upward price pressure, also have an impact on copper and may have a corresponding impact on the value of the Units. For example, copper is often mined in locations that are subject to disruption as a result of political instability, armed conflict, terrorism and labor unrest, among other factors. Production costs, particularly the cost of energy used in production, and costs associated with regulatory compliance, including environmental regulation costs, can also inflate the price of copper. These increases may not be sustainable. Any one or all of these sector-specific factors may result in volatility in copper, which could lead to corresponding volatility in the value of the units and/or significant losses to unitholders.

Introduction

Each Trust Series is a commodity pool that issues units representing fractional undivided beneficial interests in such Trust Series that may be purchased and sold on the NYSE Arca. The Trust Series are series of the Trust, a Delaware statutory trust formed on December 21, 2009.

United States Commodity Index Fund

USCI invests in Futures Contracts for commodities that are traded on the Futures Exchanges and, to a lesser extent, in order to comply with regulatory requirements or in view of market conditions, Other Commodity-Related Investments. Market conditions that USCF currently anticipates could cause USCI to invest in Other Commodity Related Investments would be those allowing USCI to obtain greater liquidity or to execute transactions with more favorable pricing.

The investment objective of USCI is for the daily changes in percentage terms of its units’ per unit NAV to reflect the daily changes in percentage terms of the Commodity Index, less USCI’s expenses. USCF does not intend to operate USCI in a fashion such that its per unit NAV will equal, in dollar terms, the spot prices of the commodities underlying the Benchmark Component Futures Contracts that comprise the Commodity Index or the prices of any particular group of Futures Contracts. The Commodity Index is comprised of 14 Futures Contracts that are selected on a monthly basis from a list of 27 possible Futures Contracts. USCI invests first in the current Benchmark Component Futures Contracts and other Futures Contracts intended to replicate the return on the current Benchmark Component Futures Contracts and, thereafter may hold Futures Contracts in a particular commodity other than one specified as the Benchmark Component Futures Contract, or may hold Other Commodity-Related Investments that may fail to closely track the Commodity Index’s total return movements. If USCI increases in size, and due to its obligations to comply with regulatory limits or due to other market pricing or liquidity factors, USCI may invest in Futures Contract months other than the designated month specified as the Benchmark Component Futures Contract, or in Other Commodity-Related Investments, which may have the effect of increasing transaction related expenses and may result in increased tracking error.

USCI seeks to achieve its investment objective by investing in Futures Contracts and Other Commodity-Related Investments such that daily changes in its per unit NAV closely track the daily changes in the price of the Commodity Index. USCI’s positions in Commodity Interests are rebalanced on a monthly basis in order to track the changing nature of the Commodity Index. If Futures Contracts relating to a particular commodity remain in the Commodity Index from one month to the next, such Futures Contracts are rebalanced to the 7.14% target weight. Specifically, on the Selection Date, it will be determined if a current Benchmark Component Futures Contract will be replaced by a new Futures Contract in either the same or different underlying commodity as a Benchmark Component Futures Contract for the following month, in which case USCI’s investments would have to be changed accordingly. In order that USCI’s trading does not unduly cause extraordinary market movements, and to make it more difficult for third parties to profit by trading based on market movements that could be expected from changes in the Benchmark Component Futures Contracts, USCI’s investments typically are not rebalanced entirely on a single day, but rather typically rebalanced over a period of four days. After fulfilling the margin and collateral requirements with respect to its Commodity Interests, USCF invests the remainder of USCI’s proceeds from the sale of units in Treasuries or cash equivalents, and/or merely hold such assets in cash (generally in interest-bearing accounts). As of December 31, 2012, USCI held 1,058 Futures Contracts on the NYMEX, 2,240 Futures Contracts on the ICE Futures, 3,405 Futures Contracts on the CBOT, 637 Futures Contracts on the CME, 5,701 Futures Contracts on the LME and did not hold any Futures Contracts on the COMEX.

74

United States Copper Index Fund

CPER invests in Futures Contracts for commodities that are traded on the COMEX and, to a lesser extent, in order to comply with regulatory requirements or in view of market conditions, Other Copper-Related Investments. Market conditions that USCF currently anticipates could cause CPER to invest in Other Copper-Related Investments would be those allowing CPER to obtain greater liquidity or to execute transactions with more favorable pricing.

The investment objective of CPER is for the daily changes in percentage terms of its units’ per unit NAV to reflect the daily changes in percentage terms of the Copper Index, less CPER’s expenses. USCF does not intend to operate CPER in a fashion such that its per unit NAV will equal, in dollar terms, the spot prices of the commodities underlying the Benchmark Component Copper Futures Contracts that comprise the Copper Index or the prices of any particular group of Futures Contracts. The Copper Index is designed to reflect the performance of the investment returns form a portfolio of copper futures contracts. The Copper Index is owned and maintained by SummerHaven Indexing and calculated and published by the NYSE Arca. The Copper Index is comprised of either two or three Eligible Copper Futures Contracts that are selected on a monthly basis based on quantitative formulas relating to the prices of the Eligible Copper Futures Contracts developed by SummerHaven Indexing. The Eligible Copper Futures Contracts that at any given time make up the Copper Index are referred to herein as “Benchmark Component Copper Futures Contracts.”

CPER seeks to achieve its investment objective by investing to the fullest extent possible in the Benchmark Component Copper Futures Contracts. Then, if constrained by regulatory requirements or in view of market conditions, CPER will invest next in other Eligible Copper Futures Contracts, and finally to a lesser extent, in other exchange traded futures contracts that are economically identical or substantially similar to the Benchmark Component Copper Futures Contracts if one or more other Eligible Copper Futures Contracts is not available. When CPER has invested to the fullest extent possible in exchange-traded futures contracts, CPER may then invest in Other Copper-Related Investments. As of December 31, 2012, CPER held 28 Futures Contracts on the COMEX.

United States Agriculture Index Fund

USAG invests in Futures Contracts for commodities that are traded on ICE Futures US, ICE Futures Canada, CBOT, KCBT and the CME, and to a lesser extent, in order to comply with regulatory requirements or in view of market conditions, Other Agriculture-Related Investments. Market conditions that USCF currently anticipates could cause USAG to invest in Other Agriculture-Related Investments would be those allowing USAG to obtain greater liquidity or to execute transactions with more favorable pricing.

The investment objective of USAG is for the daily changes in percentage terms of its units’ per unit NAV to reflect the daily changes in percentage terms of the Agriculture Index, less USAG’s expenses. USCF does not intend to operate USAG in a fashion such that its per unit NAV will equal, in dollar terms, the spot prices of the commodities underlying the Benchmark Component Futures Contracts that comprise the Agriculture Index or the prices of any particular group of Futures Contracts. The Agriculture Index is designed to reflect the performance of a diversified group of agricultural commodities. The Agriculture Index is comprised of 14 Eligible Agriculture Futures Contracts that are selected on a monthly basis based on quantitative formulas developed by SummerHaven Indexing. The Eligible Agriculture Futures Contracts that at any given time make up the Agriculture Index are referred to herein as “Benchmark Component Agriculture Futures Contracts.”.

USAG seeks to achieve its investment objective by investing to the fullest extent possible in Benchmark Component Agriculture Futures Contracts. Then, if constrained by regulatory requirements or in view of market conditions, USAG will invest next in other Eligible Agriculture Futures Contracts based on the same agricultural commodity as the futures contracts subject to such regulatory constraints or market conditions, and finally, to a lesser extent, in other exchange traded futures contracts that are economically identical or substantially similar to the Benchmark Component Agriculture Futures Contracts, if one or more Eligible Agriculture Futures Contracts is not available. When USAG has invested to the fullest extent possible in exchange-traded futures contracts, USAG may then invest in Other Agriculture-Related Interests. As of December 31, 2012, USAG held 29 Futures Contracts on the ICE Futures, 9 Futures Contracts on the CME, 4 Futures Contracts on the KCBT and 30 Futures Contracts on the CBOT.

United States Metals Index Fund

USMI invests in Futures Contracts for commodities that are traded on the NYMEX, the LME and the COMEX, and to a lesser extent, in order to comply with regulatory requirements or in view of market conditions, Other Metals-Related Investments. Market conditions that USCF currently anticipates could cause USMI to invest in Other Agriculture-Related Investments would be those allowing USMI to obtain greater liquidity or to execute transactions with more favorable pricing.

75

The investment objective of USMI is for the daily changes in percentage terms of its units’ per unit NAV to reflect the daily changes in percentage terms of the Metals Index, less USMI’s expenses. USCF does not intend to operate USMI in a fashion such that its per unit NAV will equal, in dollar terms, the spot prices of the commodities underlying the Benchmark Component Futures Contracts that comprise the Metals Index or the prices of any particular group of Futures Contracts. The Metals Index is designed to reflect the performance of a diversified group of metals. The Metals Index is comprised of 10 Eligible Metals Futures Contracts that are selected on a monthly basis based on quantitative formulas developed by SummerHaven Indexing. The Eligible Metals Futures Contracts that at any given time make up the Metals Index are referred to herein as “Benchmark Component Metals Futures Contracts.”

USMI seeks to achieve its investment objective by investing to the fullest extent possible in the Benchmark Component Metals Futures Contracts. Then, if constrained by regulatory requirements or in view of market conditions, USMI will invest next in other Eligible Metals Futures Contracts, and finally to a lesser extent, in other exchange traded futures contracts that are economically identical or substantially similar to the Benchmark Component Metals Futures Contracts if one or more other Eligible Metals Futures Contracts is not available. When USMI has invested to the fullest extent possible in exchange-traded futures contracts, USMI may then invest in other Eligible Metals Futures Contracts. As of December 31, 2012, USMI held 2 Futures Contracts on the NYMEX, 1 Futures Contract on the CME, 70 Futures Contracts on the LME and 11 Futures Contracts on the COMEX.

Regulation of Commodity Interests

The regulation of commodity interest trading in the United States and other countries is an evolving area of the law, as exemplified by the various discussions of the Dodd-Frank Act. The various statements made in this summary are subject to modification by legislative action and changes in the rules and regulations of the CFTC, the NFA, the SEC, the futures exchanges, clearing organizations and other regulatory bodies. Pending final resolution of all applicable regulatory requirements, some specific examples of how the new Dodd-Frank Act provisions and rules adopted thereunder could impact the Trust Series are discussed in “Item 1. Business” and “Item 1A. Risk Factors” in this annual report on Form 10-K.

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

Each Trust Series’ NAV is calculated once each NYSE Arca trading day. The per unit NAV for a particular trading day is released after 4:00 p.m. New York time. Trading during the core trading session on the NYSE Arca typically closes at 4:00 p.m. New York time. The Trust Series’ Administrator uses the closing prices on the relevant Futures Exchanges of the Applicable Benchmark Component Futures Contracts (determined at the earlier of the close of such exchange or 2:30 p.m. New York time) for the contracts held on the Futures Exchanges, but calculates or determines the value of all other investments of such Trust Series using market quotations, if available, or other information customarily used to determine the fair value of such investments.

Results of Operations

On July 30, 2010, USCI received a notice of effectiveness from the SEC for its registration of 50,000,000 units on Form S-1 with the SEC. On August 10, 2010, USCI listed its units on the NYSE Arca under the ticker symbol “USCI.” USCI established its initial offering per unit NAV by setting the price at $50.00 and issued 100,000 units to the initial authorized purchaser, Merrill Lynch Professional Clearing Corp., in exchange for $5,000,000 in cash on August 10, 2010. USCI commenced investment operations on August 10, 2010 by purchasing Futures Contracts traded on the Futures Exchanges. In order to satisfy NYSE Arca listing standards that at least 100,000 units be outstanding at the beginning of the trading day on the NYSE Arca, USCF purchased the initial Creation Basket from the initial Authorized Purchaser at the initial offering price. The $1,000 fee that would otherwise be charged to the Authorized Purchaser in connection with an order to create or redeem was waived in connection with the initial Creation Basket. USCF agreed not to resell the units comprising such basket except that it may require the initial Authorized Purchaser to repurchase all of these units at a per unit price equal to USCI’s per unit NAV within five days following written notice from USCF, subject to the conditions that: (i) on the date of repurchase, the initial Authorized Purchaser must immediately redeem these units in accordance with the terms of the Authorized Purchaser Agreement and (ii) immediately following such redemption at least 100,000 units of USCI remain outstanding. USCF held such initial Creation Basket until September 3, 2010, at which time the initial Authorized Purchaser repurchased the units comprising such basket in accordance with the specified conditions noted above. On September 14, 2011, USCF redeemed the 20 Sponsor Units of USCI, and on September 19, 2011, USCF purchased five units of USCI in the open market.

More units may have been issued by USCI than are outstanding due to the redemption of units.

In connection with the Second Amended and Restated Trust Agreement dated November 10, 2010, USMI, USAG and CPER were designated as three additional series of the Trust. Following the designation of the additional series, an initial capital contribution of $3,000 was transferred from USCF to the Trust. On November 10, 2010, the Trust transferred $1,000 to each of USMI, USAG and CPER, which was deemed a capital contribution to each series. On November 14, 2011, USCF received 40 Sponsor Units of CPER in exchange for the previously received capital contribution, representing a beneficial interest in CPER. On December 7, 2011, USCF redeemed the 40 Sponsor Units of CPER and purchased 40 units of CPER in the open market. On April 13, 2012, USCF received 40 Sponsor Units of USAG in exchange for the previously received capital contribution, representing a beneficial interest in USAG.

The order to permit listing CPER, USMI and USAG on the NYSE Arca was received on October 20, 2011. On November 15, 2011, CPER listed its units on the NYSE Arca under the ticker symbol “CPER.” CPER established its initial offering per unit NAV by setting the price at $25.00 and issued 100,000 units to the initial authorized purchaser, Merrill Lynch Professional Clearing Corp., in exchange for $2,500,000 in cash on November 15, 2011. The $1,000 fee that would otherwise be charged to the Authorized Purchaser in connection with an order to create or redeem was waived in connection with the initial Creation Basket.

Since its initial offering of 30,000,000 units, CPER has not registered any subsequent offerings of its units. As of December 31, 2012, CPER had issued 150,000 units, 100,000 of which were outstanding. As of December, 31, 2012, there were 29,850,000 units registered but not yet issued.

On April 13, 2012, USAG listed its units on the NYSE Arca under the ticker symbol “USAG.” USAG established its initial per unit NAV by setting the price at $25.00. On April 14, 2012, USCF purchased 2 initial Creation Baskets of USAG. In accordance with applicable requirements of Regulation M under the Securities Exchange Act of 1934, no Creation Baskets were offered to Authorized Purchasers nor were the units listed on the NYSE Arca until five business days had elapsed from the date of USCF’s purchase of the initial Creation Basket on April 4, 2012. The fee that would have otherwise been charged in connection with an order to create or redeem was waived in connection with the initial Creation Basket.

Since its initial offering of 20,000,000 units, USAG has not registered any subsequent offerings of its units. As of December 31, 2012, USAG had issued 200,000 units, 100,000 of which were outstanding. As of December 31, 2012, there were 19,800,000 units registered but not yet issued.

On June 19, 2012, USMI listed its units on the NYSE Arca under the ticker symbol “USMI.” USMI established its initial per unit NAV by setting the price at $25.00. On June 11, 2012, USCF purchased two initial Creation Baskets of USMI. In accordance with applicable requirements of Regulation M under the Securities Exchange Act of 1934, no Creation Baskets were offered to Authorized Purchasers nor were the units listed on the NYSE Arca until five business days had elapsed from the date of USCF’s purchase of the initial Creation Basket on June 11, 2012. The fee that would have otherwise been charged in connection with an order to create or redeem was waived in connection with the initial Creation Basket. On August 29, 2012, USCF redeemed one of two initial Creation Baskets of USMI, leaving its holdings to 50,000 units.

Since its initial offering of 20,000,000 units, USMI has not registered any subsequent offerings of its units. As of December 31, 2012, USMI had issued 150,000 units, 100,000 of which were outstanding. As of December 31, 2012, there were 19,850,000 units registered but not yet issued. More units may have been issued by USMI than are outstanding due to the redemption of units.

79

Unlike funds that are registered under the 1940 Act, units that have been redeemed by the Trust Series cannot be resold. As a result, each Trust Series contemplates that additional offerings of its units will be registered with the SEC in the future in anticipation of additional issuances and redemptions.

For the Year Ended December 31, 2012 Compared to the Year Ended December 31, 2011 and the Year Ended December 31, 2010

Since USCI commenced operations on August 10, 2010, the comparison of USCI’s results of operations for the year ended December 31, 2011 and the period from August 10, 2010 to December 31, 2010 may not be meaningful. In addition, since CPER commenced operations on November 15, 2011, a comparison of CPER’s results of operations for any periods prior to the period from November 15, 2011 to December 31, 2011 has not been provided and a comparison of CPER’s results of operations for the year ended December 31, 2012 and the period from November 15, 2011 to December 31, 2011 may not be meaningful. In addition, since USAG and USMI commenced operations on April 13, 2012 and June 19, 2012, respectively, a comparison of each of USAG’s and USMI’s results of operations for any periods prior to the period from April 13, 2012 to December 31, 2012 and June 19, 2012 to December 31, 2012, respectively, has not been provided.

USCI held 87.72% of its cash assets in overnight deposits and Treasuries at the Custodian, while 12.28% of the cash balance was held as investments in Treasuries and margin deposits for the Futures Contracts purchased. The ending per unit unit NAV on December 31, 2012 was $58.45.

By comparison, as of December 31, 2011, USCI’s total unrealized loss on Futures Contracts owned or held on that day was $22,976,692, and USCI established cash deposits and investments in Treasuries that were equal to $374,465,568. USCI held 82.92% of its cash assets in overnight deposits and investments in Treasuries at the Custodian, while 17.08% of the cash balance was held as investments in Treasuries and margin deposits for the Futures Contracts purchased. The increase in cash assets in overnight deposits and investments in Treasuries for the year ended December 31, 2012, as compared to the year ended December 31, 2011, was the result of USCI’s greater size during the year ended December 31, 2012 as measured by total net assets. The ending per unit NAV on December 31, 2011 was $58.47. The decrease in the per unit NAV for the year ended December 31, 2012, as compared to the year ended December 31, 2011, was primarily due to the decrease in the prices of the Futures Contracts held by USCI.

By comparison, as of December 31, 2010, USCI’s total unrealized gain on Futures Contracts owned or held on that day was $7,417,317, and USCI established cash deposits and investments in Treasuries that were equal to $95,669,058. USCI held 91.40% of its cash assets in overnight deposits and investments in Treasuries at the Custodian, while 8.60% of the cash balance was held as investments in Treasuries and margin deposits for the Futures Contracts purchased. The increase in cash assets in overnight deposits and investments in Treasuries for the year ended December 31, 2011 compared to the period ended December 31, 2010, was the result of USCI’s greater size as of December 31, 2011 as measured by total net assets. The ending per unit NAV on December 31, 2010 was $64.37. The decrease in the per unit NAV for the year ended December 31, 2011, as compared to the period ended December 31, 2010, was primarily due to the decrease in the prices of the Futures Contracts.

CPER held 84.17% of its cash assets in overnight deposits and investments in Treasuries at the Custodian, while 15.83% of the cash balance was held as margin deposits for the Futures Contracts purchased. The increase in cash assets in overnight deposits and investments in Treasuries for the year ended December 31, 2012, as compared to the period ended December 31, 2011, was the result of CPER’s greater size as of December 31, 2012 as measured by total net assets. The ending per unit NAV on December 31, 2011 was $24.47. The increase in the per unit NAV for the year ended December 31, 2012, as compared to the period ended December 31, 2011, was primarily due to the increase in the prices of the Futures Contracts that CPER held.

As of December 31, 2012, USAG’s total unrealized loss on Futures Contracts owned or held on that day was $119,155, and USAG established cash deposits and investments in Treasuries that were equal to $2,679,845.

Portfolio Expenses. Each Trust Series’ expenses consist of investment management fees, brokerage fees and commissions, certain offering costs, the fees and expenses of the independent directors of USCF and expenses relating to tax accounting and reporting requirements. The management fee that each Trust Series pays to USCF is calculated as a percentage of the total net assets of such Trust Series. Each Trust Series is contractually obligated to pay USCF a management fee of 0.95% of its average daily total net assets. Effective as of May 29, 2012 (and continuing through at least March 31, 2013), USCF voluntarily waived the management fee paid by each of CPER and USAG from 0.95% to 0.65% and 0.80% per annum of average daily total net assets, respectively. Effective as of May 30, 2012 (and continuing through at least March 31, 2013), USCF voluntarily waived the management fee paid by USMI from 0.95% to 0.70% per annum of average daily total net assets. The reduced fee for USMI became operational as of June 19, 2012, the date USMI became listed on the NYSE Arca. Each fee is accrued daily and paid monthly.

During the year ended December 31, 2012, the average daily total net assets of USCI were $428,436,180. The management fee incurred daily by USCI during the year amounted to $4,070,144. By comparison, during the year ended December 31, 2011, the average daily total net assets of USCI were $397,802,693. The management fee incurred by USCI during the year amounted to $3,779,126. By comparison, during the period ended December 31, 2010, the average daily total net assets of USCI were $39,600,480. The management fee paid by USCI during the period amounted to $148,421.

During the year ended December 31, 2012, the daily average total net assets of CPER were $2,552,489. The management fee incurred by CPER during the year amounted to $19,823. By comparison, during the period ended December 31, 2011, the average daily total net assets of CPER were $2,444,511. The management fee incurred by CPER during the period amounted to $2,990.

During the period ended December 31, 2012, the average daily total net assets of USAG were $2,948,838. The management fee incurred by USAG during the period amounted to $17,492.

81

During the period ended December 31, 2012, the average daily total net assets of USMI were $2,849,399. The management fee incurred by USMI during the period amounted to $10,681.

In addition to the management fee, each Trust Series pays all brokerage fees and other expenses, including tax reporting costs, ongoing registration or other fees paid to the SEC, FINRA and any other regulatory agency in connection with offers and sales of its units subsequent to the initial offering and all legal, accounting, printing and other expenses associated therewith. The gross total of these fees and expenses for USCI for the year ended December 31, 2012 was $856,041, as compared to $821,686 for the year ended December 31, 2011 and $98,463 for the period ended December 31, 2010. The increase in gross total fees and expenses excluding management fees for the year ended December 31, 2012 compared to the year ended December 31, 2011 was primarily due to USCI’s increased size during the year ended December 31, 2012. The increase in gross total fees and expenses excluding management fees for the year ended December 31, 2011 compared to the period ended December 31, 2010 was primarily due to the fact that USCI was operating for a portion of the period ended December 31, 2010 versus a full year of operations for the year ended December 31, 2011. For the years ended December 31, 2012 and December 31, 2011 and the period ended December 31, 2010, USCI did not incur any fees or other expenses relating to the registration or offering of additional units. For a portion of the year ended December 31, 2011 and during the period ended December 31, 2010, an expense waiver was in effect which offset certain of the expenses incurred by USCI. The total amount of the expense waiver was $36,907 for the year ended December 31, 2011 and $51,397 for the period ended December 31, 2010. For the year ended December 31, 2011 and the period ended December 31, 2010, the expenses of USCI, including management fees, commissions, and all other expenses, before allowance for the expense waiver, totaled $4,600,812 and $246,884, respectively, and after allowance for the expense waiver, totaled $4,563,905 and $195,487, respectively.

Each Trust Series is responsible for paying its portion of the directors’ and officers’ liability insurance of such Trust Series and the Related Public Funds. In addition, as of July 8, 2011, each Trust Series is responsible for paying the fees and expenses of the independent directors who also serve as audit committee members of the Trust Series and the Related Public Funds. Each Trust Series shares the fees and expenses on a pro rata basis with each other Trust Series and 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, 2012 amounted to a total of $540,586 for the Trust Series and the Related Public Funds. USCI’s portion of such fees and expenses for the year ended December 31, 2012 was $68,533, CPER’s portion of such fees and expenses for the year ended December 31, 2012 was $415, USAG’s portion of such fees and expenses for the year ended December 31, 2012 was $220 and USMI’s portion of such fees and expenses for the year ended December 31, 2012 was $154. By comparison, for the year ended December 31, 2011, these fees and expenses amounted to a total of $607,582 for USCI, CPER and the Related Public Funds. USCI’s portion of such fees and expenses for the year ended December 31, 2011 was $31,792 and CPER’s portion of such fees and expenses for the year ended December 31, 2011 was $32. The decrease in directors’ fees and expenses for the year ended December 31, 2012, as compared to the year ended December 31, 2011 was primarily due to the non-incurrence of the independent directors’ deferred compensation expense for the year ended December 31, 2012, which was amortized during the years ended December 31, 2011 and 2010. By comparison, for the year ended December 31, 2010, these fees and expenses amounted to a total of $1,107,140 for all Related Public Funds, except USCI, USAG, CPER and USMI. The decrease in directors’ fees and expenses for the year ended December 31, 2011, as compared to the year ended December 31, 2010, was primarily due to the non-incurrence of the independent directors’ deferred compensation expense for the year ended December 31, 2011, the majority of which was amortized in the year ended December 31, 2010.

Each Trust Series also incurs commissions to brokers for the purchase and sale of Futures Contracts, Other Related Investments or Treasuries. During the year ended December 31, 2012, total commissions accrued to brokers amounted to $310,109 for USCI. Of this amount, approximately $296,759 was a result of rebalancing costs and approximately $13,350 was the result of trades necessitated by creation and redemption activity. By comparison, during the year ended December 31, 2011, total commissions accrued to brokers amounted to $307,284 for USCI. Of this amount, approximately $286,584 was a result of rebalancing costs and approximately $20,700 was the result of trades necessitated by creation and redemption activity. By comparison, during the period ended December 31, 2010, total commissions accrued to brokers amounted to $23,632 for USCI. Of this amount, approximately $18,532 was a result of rebalancing costs and approximately $5,100 was the result of trades necessitated by creation and redemption activity. The increase in USCI’s total commissions accrued to brokers for the year ended December 31, 2012 as compared to the year ended December 31, 2011, was primarily due to an increase in USCI’s total net assets for the year ended December 31, 2012. The increase in USCI’s total commissions accrued to brokers for the year ended December 31, 2011 as compared to the period ended December 31, 2010, was primarily due an increase in USCI’s total net assets for the year ended December 31, 2011 and the fact that USCI was operating for only a portion of the period ended December 31, 2010 versus a full year of operations for the year ended December 31, 2011. As an annualized percentage of average total net assets, USCI’s figure for the year ended December 31, 2012 represents approximately 0.07% of USCI’s average total net assets. By comparison, USCI’s figure for the year ended December 31, 2011 represented approximately 0.08% of USCI’s average total net assets and the figure for the period ended December 31, 2010 represented approximately 0.15% of USCI’s 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.

During the year ended December 31, 2012, total commissions accrued to brokers amounted to $956 for CPER. Of this amount, approximately $799 was a result of rebalancing costs and approximately $157 was the result of trades necessitated by creation and redemption activity.

The increase in CPER’s total commissions accrued to brokers for the year ended December 31, 2012 as compared to the period ended December 31, 2011, was primarily due a slight increase in CPER’s total net assets for the year ended December 31, 2012 and that CPER was operating for only a portion of the period ended December 31, 2011 versus a full year of operations for the year ended December 31, 2012. As an annualized percentage of average total net assets, CPER’s figure for the year ended December 31, 2012 represents approximately 0.04% of CPER’s average total net assets. By comparison, CPER’s figure for the period ended December 31, 2011 represents approximately 0.06% of CPER’s 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.

During the period ended December 31, 2012, total commissions accrued to brokers amounted to $2,632 for USAG.

USCF has voluntarily agreed to pay certain expenses normally borne by each of CPER, USAG and USMI to the extent that such expenses exceed 0.15% (15 basis points) of each of CPER’s, USAG’s and USMI’s NAV, on an annualized basis, through at least June 30, 2013. USCF has no obligation to continue such payments into subsequent periods. For the year ended December 31, 2012, USCF waived $96,364, $76,851 and $59,316 for each of CPER, USAG and USMI, respectively. This voluntary expense waiver is in addition to those amounts USCF is contractually obligated to pay as described in Note 5 in Item 8 of this annual report on Form 10-K.

Interest Income. Each Trust Series seeks to invest its assets such that it holds Futures Contracts and Other Related Investments in an amount equal to the total net assets of its portfolio. Typically, such investments do not require each Trust Series to pay the full amount of the contract value at the time of purchase, but rather require each Trust Series to post an amount as a margin deposit against the eventual settlement of the contract. As a result, each Trust Series retains an amount that is approximately equal to its total net assets, which each Trust Series invests in Treasuries, cash and/or cash equivalents. This includes both the amount on deposit with the FCM as margin and in Treasuries, as well as unrestricted cash and cash equivalents held with each Trust Series’ Custodian. The Treasuries, cash and/or cash equivalents earn income that accrues on a daily basis. For the year ended December 31, 2012, USCI earned $278,476 in interest income on such Treasuries, cash and/or cash equivalents. Based on USCI’s average daily total net assets, this was equivalent to an annualized yield of approximately 0.07%. USCI purchased Treasuries during the year ended December 31, 2012 and also held cash and/or cash equivalents during this time period. By comparison, for the year ended December 31, 2011 and the period ended December 31, 2010, USCI earned $179,139 and $11,079, respectively, in interest income on such Treasuries, cash and/or cash equivalents. Based on USCI’s average daily total net assets, this was equivalent to an annualized yield of approximately 0.05% and 0.07%, respectively. USCI purchased Treasuries during the year ended December 31, 2011 and the period ended December 31, 2010 and also held cash and/or cash equivalents during these time periods. Interest rates on short-term investments, including cash equivalents and Treasuries, were higher during the year ended December 31, 2012 compared to the year ended December 31, 2011 and lower compared to the period ended December 31, 2010. As a result, the amount of income earned by USCI as a percentage of average total net assets was higher during the year ended December 31, 2012 compared to the year ended December 31, 2011 and equivalent to the period ended December 31, 2010.

For the year ended December 31, 2012, CPER earned $1,607 in interest income on such Treasuries, cash and/or cash equivalents. Based on CPER’s average daily total net assets, this was equivalent to an annualized yield of approximately 0.06%.

Of this amount, approximately $238 was a result of rebalancing costs and there were no trades necessitated by creation or redemption activity. As an annualized percentage of average daily total net assets, USMI’s figure for the three months ended December 31, 2012 represents approximately 0.04% of USMI’s average daily total net assets. However, there can be no assurance that commission costs and portfolio turnover will not cause commission expenses to rise in future quarters.

The fees and expenses associated with each Trust Series’ audit expenses and tax accounting and reporting requirements are paid by such Trust Series. These costs are estimated to be for the year ended December 31, 2012 for USCI, $50,000 for the year ended December 31, 2012 for CPER, $75,000 for the year ended December 31, 2012 for USAG and $75,000 for the year ended December 31, 2012 for USMI. USCF has voluntarily agreed to pay certain expenses normally borne by each of CPER, USAG and USMI to the extent that such expenses exceed 0.15% (15 basis points) of each of CPER’s, USAG’s and USMI’s NAV, on an annualized basis, through at least June 30, 2013. USCF has no obligation to continue such payments into subsequent periods. For the three months ended December 31, 2012, USCF waived $31,459, $30,132 and $30,139 for each of CPER, USAG and USMI, respectively. This voluntary expense waiver is in addition to those amounts USCF is contractually obligated to pay as described in Note 5 in Item 8 of this annual report on Form 10-K.

Interest Income. Each Trust Series seeks to invest its assets such that it holds Futures Contracts and Other Related Investments in an amount equal to the total net assets of its portfolio. Typically, such investments do not require each Trust Series to pay the full amount of the contract value at the time of purchase, but rather require each Trust Series to post an amount as a margin deposit against the eventual settlement of the contract. As a result, each Trust Series retains an amount that is approximately equal to its total net assets, which each Trust Series invests in Treasuries, cash and/or cash equivalents. This includes both the amount on deposit with the FCM as margin and in Treasuries, as well as unrestricted cash and cash equivalents held with each Trust Series’ Custodian. The Treasuries, cash and/or cash equivalents earn income that accrues on a daily basis. For the three months ended December 31, 2012, USCI earned $100,972 in interest income on such Treasuries, cash and/or cash equivalents. Based on USCI’s average daily total net assets, this was equivalent to an annualized yield of approximately 0.08%. USCI purchased Treasuries during the three months ended December 31, 2012 and also held cash and/or cash equivalents during this time period. By comparison, for the three months ended December 31, 2011 and 2010, USCI earned $26,818 and $10,619, respectively, in interest income on such Treasuries, cash and/or cash equivalents. Based on USCI’s average daily total net assets, this was equivalent to an annualized yield of approximately 0.03% and 0.08%, respectively. USCI purchased Treasuries during the three months ended December 31, 2011 and 2010 and also held cash and/or cash equivalents during these time periods. Interest rates on short-term investments, including cash, cash equivalents and Treasuries, were higher during the three months ended December 31, 2012 compared to the three months ended December 31, 2011 and lower compared to the three months ended December 31, 2010. As a result, the amount of income earned by USCI as a percentage of average total net assets was higher during the three months ended December 31, 2012 compared to the three months ended December 31, 2011 and equivalent compared to the three months ended December 31, 2010.

For the three months ended December 31, 2012, CPER earned $514 in interest income on such Treasuries, cash and/or cash equivalents. Based on CPER’s average daily total net assets, this was equivalent to an annualized yield of approximately 0.08%. CPER purchased Treasuries during the three months ended December 31, 2012 and also held cash and/or cash equivalents during this time period. By comparison, for the period ended December 31, 2011, CPER earned $92 in interest income on such Treasuries, cash and/or cash equivalents. Based on CPER’s average daily total net assets, this was equivalent to an annualized yield of approximately 0.03%. CPER purchased Treasuries during the period ended December 31, 2011 and also held cash and/or cash equivalents during this time period. Interest rates on short-term investments, including cash, cash equivalents and Treasuries, were higher during the three months ended December 31, 2012 compared to the period ended December 31, 2011. As a result, the amount of income earned by CPER as a percentage of average total net assets was higher during the three months ended December 31, 2012 compared to the period ended December 31, 2011.

87

For the three months ended December 31, 2012, USAG earned $559 in interest income on such Treasuries, cash and/or cash equivalents. Based on USAG’s average daily total net assets, this was equivalent to an annualized yield of approximately 0.08%. USAG purchased Treasuries during the three months ended December 31, 2012 and also held cash and/or cash equivalents during this time period.

For the three months ended December 31, 2012, USMI earned $570 in interest income on such Treasuries, cash and/or cash equivalents. Based on USMI’s average daily total net assets, this was equivalent to an annualized yield of approximately 0.09%. USMI purchased Treasuries during the three months ended December 31, 2012 and also held cash and/or cash equivalents during this time period.

The table below reflects the same listing of monthly Benchmark Component Futures Contracts as the tables above with two changes. First, the table below includes a column showing the change in the spot price of each of the 27 commodities for the year ended December 31, 2012. Second, while the tables above list the order of the commodities alphabetically (first by which of the six sectors a commodity falls into and then within each sector), the table below lists the commodities from the commodity that had the highest positive change in spot price to the commodity that had the lowest positive change or largest negative change in spot price. Investors are cautioned that the change in the spot price of a given commodity does not represent the actual return that USCI might have earned on any holdings in futures contracts based on that commodity. This is due to two factors. First, the return on a futures contract may be higher, or lower, than the change in the spot price of the commodity due to the impact of backwardation or contango. Second, USCI may not have owned any such futures contract for the entire time period represented in the table below. Thus, USCI’s total actual return on its holdings in any of the commodities shown below may be higher, or lower, than the actual change in the spot price of the particular commodity.

Tracking each Trust Series’ Benchmark

USCF seeks to manage each Trust Series’ portfolio such that changes in its average daily per unit NAV, on a percentage basis, closely track the changes in the price of the Applicable Index, 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 a Trust Series’ per unit NAV is within a range of 90% to 110% (0.9 to 1.1) of the average daily change in the price of the Applicable Index. As an example, if the average daily movement of the price of the Applicable Index for a particular 30-valuation day time period was 0.50% per day, USCF would attempt to manage the portfolio such that the average daily movement of the per unit NAV during that same time period fell between 0.45% and 0.55% (i.e., between 0.9 and 1.1 of the Applicable Index’s results). Each Trust Series’ portfolio management goals do not include trying to make the nominal price of its per unit NAV equal to the nominal price of the Applicable Index, the nominal price of any particular commodity Futures Contract or the spot price for any particular commodity. USCF believes that it is not practical to manage the portfolio to achieve such an investment goal when investing in listed Futures Contracts.

USCI

For the 30 valuation days ended December 31, 2012, the simple average daily change in the Commodity Index was 0.001%, while the simple average daily change in the per unit NAV of USCI over the same time period was (0.006)%. The average daily difference was (0.007)% (or (0.7) basis points, where 1 basis point equals 1/100 of 1%). As a percentage of the daily movement of the Commodity Index, the average error in daily tracking by the per unit NAV was (11.822)%, meaning that over this time period USCI’s tracking error was outside the plus or minus 10% range established as its benchmark tracking goal. The first chart below shows the daily movement of USCI’s per unit NAV versus the daily movement of the Commodity Index for the 30-valuation day period ended December 31, 2012. The second chart below shows the monthly total returns of USCI as compared to the monthly value of the Benchmark Component Futures Contracts since inception.

Since the commencement of the offering of USCI’s units to the public on August 10, 2010 to December 31, 2012, the simple average daily change in the Commodity Index was 0.036%, while the simple average daily change in the per unit NAV of USCI over the same time period was 0.031%. The average daily difference was (0.005)% (or (0.5) basis points, where 1 basis point equals 1/100 of 1%). As a percentage of the daily movement of the Commodity Index, the average error in daily tracking by the per unit NAV was (2.96)%, meaning that over this time period USCI’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 USCI versus the return of the Commodity Index can be calculated by comparing the actual return of USCI, measured by changes in its NAV, versus the expected changes in its NAV under the assumption that USCI’s returns had been exactly the same as the daily changes in the price of the Commodity Index.

For the year ended December 31, 2012, the actual total return of USCI as measured by changes in its per unit NAV was (0.03)%. This is based on an initial per unit NAV of $58.47 on December 31, 2011 and an ending per unit NAV as of December 31, 2012 of $58.45. During this time period, USCI made no distributions to its unitholders. However, if USCI’s daily changes in its per unit NAV had instead exactly tracked the changes in the daily return of the Commodity Index, USCI would have had an estimated per unit NAV of $59.27 as of December 31, 2012, for a total return over the relevant time period of 1.37%. The difference between the actual per unit NAV total return of USCI of (0.03)% and the expected total return based on the Commodity Index of 1.37% was an error over the time period of (1.40)%, which is to say that USCI’s actual total return underperformed the Commodity Index result by that percentage. USCF believes that a portion of the difference between the actual total return and the expected Commodity Index total return can be attributed to the net impact of the expenses that USCI pays, offset in part by the income that USCI collects on its cash and cash equivalent holdings. During the year ended December 31, 2012, USCI earned interest income of $278,476, which is equivalent to a weighted average income rate of approximately 0.07% for such period. In addition, during the year ended December 31, 2012, USCI also collected $12,950 from its Authorized Purchasers for creating or redeeming baskets of units. This income also contributed to USCI’s actual total return. However, if the total assets of USCI continue to increase, USCF believes that the impact on actual total returns of these fees from creations and redemptions will diminish as a percentage of the actual total return. During the year ended December 31, 2012, USCI incurred total expenses of $4,926,185. Income from interest and Authorized Purchaser collections net of expenses was $(4,634,759), which is equivalent to a weighted average net income rate of approximately (1.08)% for the year ended December 31, 2012.

91

By comparison, for the year ended December 31, 2011, the actual total return of USCI as measured by changes in its per unit NAV was (9.17)%. This is based on an initial per unit NAV of $64.37 on December 31, 2010 and an ending per unit NAV as of December 31, 2011 of $58.47. During this time period, USCI made no distributions to its unitholders. However, if USCI’s daily changes in its per unit NAV had instead exactly tracked the changes in the daily return of the Commodity Index, USCI would have had an estimated per unit NAV of $59.20 as of December 31, 2011, for a total return over the relevant time period of (8.03)%. The difference between the actual per unit NAV total return of USCI of (9.17)% and the expected total return based on the Commodity Index of (8.03)% was an error over the time period of (1.14)%, which is to say that USCI’s actual total return underperformed the Commodity Index result by that percentage. USCF believes that a portion of the difference between the actual total return and the expected Commodity Index total return can be attributed to the net impact of the expenses that USCI paid, offset in part by the income that USCI collected on its cash and cash equivalent holdings. During the year ended December 31, 2011, USCI earned interest income of $179,139, which is equivalent to a weighted average income rate of approximately 0.05% for such period. In addition, during the year ended December 31, 2011, USCI also collected $57,300 from its Authorized Purchasers for creating or redeeming baskets of units. This income also contributed to USCI’s actual total return. However, if the total assets of USCI continue to increase, USCF believes that the impact on actual total returns of these fees from creations and redemptions will diminish as a percentage of the actual total return. During the year ended December 31, 2011, USCI incurred net expenses of $4,563,905. Income from interest and Authorized Purchaser collections net of expenses was $(4,327,466), which is equivalent to a weighted average net income rate of approximately (1.09)% for the year ended December 31, 2011.

By comparison, for the period ended December 31, 2010, the actual total return of USCI as measured by changes in its per unit NAV was 28.74%. This is based on an initial per unit NAV of $50.00 on August 10, 2010 and an ending per unit NAV as of December 31, 2010 of $64.37. During this time period, USCI made no distributions to its unitholders. However, if USCI’s daily changes in its per unit NAV had instead exactly tracked the changes in the daily return of the Commodity Index, USCI would have had an estimated per unit NAV of $64.49 as of December 31, 2010, for a total return over the relevant time period of 28.98%. The difference between the actual per unit NAV total return of USCI of 28.74% and the expected total return based on the Commodity Index of 28.98% was an error over the time period of (0.24)%, which is to say that USCI’s actual total return underperformed the Commodity Index result by that percentage. USCF believes that a portion of the difference between the actual total return and the expected Commodity Index total return can be attributed to the net impact of the expenses that USCI paid, offset in part by the income that USCI collected on its cash and cash equivalent holdings. During the period ended December 31, 2010, USCI earned interest income of $11,079, which is equivalent to a weighted average income rate of approximately 0.07% for such period. In addition, during the period ended December 31, 2010, USCI also collected $15,000 from its Authorized Purchasers for creating or redeeming baskets of units. This income also contributed to USCI’s actual total return. However, if the total assets of USCI continue to increase, USCF believes that the impact on actual total returns of these fees from creations and redemptions will diminish as a percentage of the actual total return. During the period ended December 31, 2010, USCI incurred net expenses of $195,487. Income from interest and Authorized Purchaser collections net of expenses was $(169,408), which is equivalent to a weighted average net income rate of approximately (1.08)% for the period ended December 31, 2010.

CPER

For the 30 valuation days ended December 31, 2012, the simple average daily change in the Copper Index was 0.171%, while the simple average daily change in the per unit NAV of CPER over the same time period was 0.169%. 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 Copper Index, the average error in daily tracking by the per unit NAV was (0.762)%, meaning that over this time period CPER’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 CPER’s per unit NAV versus the daily movement of the Copper Index for the 30-valuation day period ended December 31, 2012. The second chart below shows the monthly total returns of CPER as compared to the monthly value of the Benchmark Component Copper Futures Contracts since inception.

Since the commencement of the offering of CPER’s units to the public on November 15, 2011 to December 31, 2012, the simple average daily change in the Copper Index was 0.020%, while the simple average daily change in the per unit NAV of CPER over the same time period was 0.016%. The average daily difference was 0.005% (or 0.5 basis points, where 1 basis point equals 1/100 of 1%). As a percentage of the daily movement of the Copper Index, the average error in daily tracking by the per unit NAV was (2.243)%, meaning that over this time period CPER’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 CPER versus the return of the Copper Index can be calculated by comparing the actual return of CPER, measured by changes in its per unit NAV, versus the expected changes in its per unit NAV under the assumption that CPER’s returns had been exactly the same as the daily changes in the price of the Copper Index.

93

For the year ended December 31, 2012, the actual total return of CPER as measured by changes in its per unit NAV was 3.92%. This is based on an initial per unit NAV of $24.47 on December 31, 2011 and an ending per unit NAV as of December 31, 2012 of $25.43. During this time period, CPER made no distributions to its unitholders. However, if CPER’s daily changes in its per unit NAV had instead exactly tracked the changes in the daily return of the Copper Index, CPER would have had an estimated per unit NAV of $25.70 as of December 31, 2012, for a total return over the relevant time period of 5.03%. The difference between the actual per unit NAV total return of CPER of 3.92% and the expected total return based on the Copper Index of 5.03% was an error over the time period of (1.11)%, which is to say that CPER’s actual total return underperformed the Copper Index result by that percentage. USCF believes that a portion of the difference between the actual total return and the expected Copper Index total return can be attributed to the net impact of the expenses that CPER pays, offset in part by the income that CPER collects on its cash and cash equivalent holdings. During the year ended December 31, 2012, CPER earned interest income of $1,607, which is equivalent to a weighted average income rate of approximately 0.06% for such period. In addition, during the year ended December 31, 2012, CPER also collected $1,350 from its Authorized Purchasers for creating or redeeming baskets of units. This income also contributed to CPER’s actual total return. During the year ended December 31, 2012, CPER incurred net expenses of $25,023. Income from interest and Authorized Purchaser collections net of expenses was $(22,066), which is equivalent to a weighted average net income rate of approximately (0.86)% for the year ended December 31, 2012.

By comparison, for the period ended December 31, 2011, the actual total return of CPER as measured by changes in its per unit NAV was (2.12)%. This is based on an initial per unit NAV of $25.00 on November 15, 2011 and an ending per unit NAV as of December 31, 2011 of $24.47. During this time period, CPER made no distributions to its unitholders. However, if CPER’s daily changes in its per unit NAV had instead exactly tracked the changes in the daily return of the Copper Index, CPER would have had an estimated per unit NAV of $24.50 as of December 31, 2011, for a total return over the relevant time period of (2.00)%. The difference between the actual per unit NAV total return of CPER of (2.12)% and the expected total return based on the Copper Index of (2.00)% was an error over the time period of (0.12)%, which is to say that CPER’s actual total return underperformed the Copper Index result by that percentage. USCF believes that a portion of the difference between the actual total return and the expected Copper Index total return can be attributed to the net impact of the expenses that CPER paid, offset in part by the income that CPER collected on its cash and cash equivalent holdings. During the period ended December 31, 2011, CPER earned interest income of $92, which is equivalent to a weighted average income rate of approximately 0.03% for such period. During the period ended December 31, 2011, CPER did not collect any fees from its Authorized Purchasers for creating or redeeming baskets of units. During the period ended December 31, 2011, CPER incurred net expenses of $3,671. Income from interest and Authorized Purchaser collections net of expenses was $(3,579), which is equivalent to a weighted average net income rate of approximately (1.14)% for the period ended December 31, 2011.

USAG

For the 30-valuation days ended December 31, 2012, the simple average daily change in the Agriculture Index was (0.054)%, while the simple average daily change in the per unit NAV of USAG over the same time period was (0.054)%. The average daily difference was 0.000% (or 0.0 basis points, where 1 basis point equals 1/100 of 1%). As a percentage of the daily movement of the Agriculture Index, the average error in daily tracking by the per unit NAV was (7.13)%, meaning that over this time period USAG’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 USAG’s per unit NAV versus the daily movement of the Agriculture Index for the 30-valuation day period ended December 31, 2012. The second chart below shows the monthly total returns of USAG as compared to the monthly value of the Benchmark Component Agriculture Futures Contracts since inception.

Since the commencement of the offering of USAG’s units to the public on April 13, 2012 to December 31, 2012, the simple average daily change in the Agriculture Index was 0.022%, while the simple average daily change in the per unit NAV of USAG over the same time period was 0.016%. The average daily difference was (0.005)% (or (0.5) basis points, where 1 basis point equals 1/100 of 1%). As a percentage of the daily movement of the Agriculture Index, the average error in daily tracking by the per unit NAV was 1.244%, meaning that over this time period USAG’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 USAG versus the return of the Agriculture Index can be calculated by comparing the actual return of USAG, measured by changes in its per unit NAV, versus the expected changes in its per unit NAV under the assumption that USAG’s returns had been exactly the same as the daily changes in the price of the Agriculture Index.

95

For the period ended December 31, 2012, the actual total return of USAG as measured by changes in its per unit NAV was 2.24%. This is based on an initial per unit NAV of $25.00 on April 13, 2012 and an ending per unit NAV as of December 31, 2012 of $25.56. During this time period, USAG made no distributions to its unitholders. However, if USAG’s daily changes in its per unit NAV had instead exactly tracked the changes in the daily total return of the Agriculture Index, USAG would have had an estimated per unit NAV of $25.80 as of December 31, 2012, for a total return over the relevant time period of 3.20%. The difference between the actual per unit NAV total return of USAG of 2.24% and the expected total return based on the Agriculture Index of 3.20% was an error over the time period of (0.96)%, which is to say that USAG’s actual total return underperformed the Agriculture Index result by that percentage. USCF believes that a portion of the difference between the actual total return and the expected Agriculture Index total return can be attributed to the net impact of the expenses that USAG pays, offset in part by the income that USAG collects on its cash and cash equivalent holdings. During the period ended December 31, 2012, USAG earned interest income of $1,573, which is equivalent to a weighted average income rate of approximately 0.07% for such period. In addition, during the period ended December 31, 2012, USAG also collected $2,700 from its Authorized Purchasers for creating or redeeming baskets of units. This income also contributed to USAG’s actual total return. However, if the total assets of USAG continue to increase, USCF believes that the impact on actual total returns of these fees from creations and redemptions will diminish as a percentage of the actual total return. During the period ended December 31, 2012, USAG incurred net expenses of $23,523. Income from interest and Authorized Purchaser collections net of expenses was $(19,250), which is equivalent to a weighted average net income rate of approximately (0.91)% for the period ended December 31, 2012.

USMI

For the 30-valuation days ended December 31, 2012, the simple average daily change in the Metals Index was 0.088%, while the simple average daily change in the per unit NAV of USMI over the same time period was 0.098%. The average daily difference was 0.010% (or 1 basis point, where 1 basis point equals 1/100 of 1%). As a percentage of the daily movement of the Metals Index, the average error in daily tracking by the per unit NAV was 1.51%, meaning that over this time period USMI’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 USMI’s per unit NAV versus the daily movement of the Metals Index for the 30-valuation day period ended December 31, 2012. The second chart below shows the monthly total returns of USMI as compared to the monthly value of the Benchmark Component Metals Futures Contracts since inception.

Since the commencement of the offering of USMI’s units to the public on June 19, 2012 to December 31, 2012, the simple average daily change in the Metals Index was 0.051%, while the simple average daily change in the per unit NAV of USMI over the same time period was 0.048%. The average daily difference was (0.003)% (or (0.3) basis points, where 1 basis point equals 1/100 of 1%). As a percentage of the daily movement of the Metals Index, the average error in daily tracking by the per unit NAV was (1.59)%, meaning that over this time period USMI’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 USMI versus the return of the Metals Index can be calculated by comparing the actual return of USMI, measured by changes in its per unit NAV, versus the expected changes in its per unit NAV under the assumption that USMI’s returns had been exactly the same as the daily changes in the price of the Metals Index.

97

For the period ended December 31, 2012, the actual total return of USMI as measured by changes in its per unit NAV was 5.88%. This is based on an initial per unit NAV of $25.00 on June 19, 2012 and an ending per unit NAV as of December 31, 2012 of $26.47. During this time period, USMI made no distributions to its unitholders. However, if USMI’s daily changes in its per unit NAV had instead exactly tracked the changes in the daily total return of the Metals Index, USMI would have had an estimated per unit NAV of $26.57 as of December 31, 2012, for a total return over the relevant time period of 6.28%. The difference between the actual per unit NAV total return of USMI of 5.88% and the expected total return based on the Metals Index of 6.28% was an error over the time period of (0.40)% which is to say that USMI’s actual total return underperformed the Metals Index result by that percentage. USCF believes that a portion of the difference between the actual total return and the expected Metals Index total return can be attributed to the net impact of the expenses that USMI pays, offset in part by the income that USMI collects on its cash and cash equivalent holdings. During the period ended December 31, 2012, USMI earned interest income of $1,270, which is equivalent to a weighted average income rate of approximately 0.08% for such period. In addition, during the period ended December 31, 2012, USMI also collected $1,350 from its Authorized Purchasers for creating or redeeming baskets of units. This income also contributed to USMI’s actual total return. However, if the total assets of USMI continue to increase, USCF believes that the impact on actual total returns of these fees from creations and redemptions will diminish as a percentage of the actual total return. During the period ended December 31, 2012, USMI incurred net expenses of $13,838. Income from interest and Authorized Purchaser collections net of expenses was $(11,218), which is equivalent to a weighted average net income rate of approximately (0.74)% for the period ended December 31, 2012.

Factors That Can Impact Ability to Track the Applicable Index

There are currently three factors that have impacted or are most likely to impact a Trust Series’ ability to accurately track an Applicable Index.

First, a Trust Series may buy or sell its holdings in the then current Applicable Benchmark Component Futures Contracts at a price other than the closing settlement price of that contract on the day during which such Trust Series executes the trade. In that case, a Trust Series may pay a price that is higher, or lower, than that of the Applicable Benchmark Component Futures Contracts, which could cause the changes in the daily per unit NAV of a Trust Series to either be too high or too low relative to the daily changes in the price of the Applicable Index. During the year ended December 31, 2012, USCF attempted to minimize the effect of these transactions by seeking to execute its purchase or sale of the Applicable Benchmark Component Futures Contracts at, or as close as possible to, the end of the day settlement price. However, it may not always be possible for a Trust Series 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 a Trust Series’ attempt to track the Applicable Index over time.

Second, each Trust Series earns interest income on its cash, cash equivalents and Treasuries. A Trust Series is not required to distribute any portion of its income to its unitholders and none of the Trust Series made any distributions to unitholders during the year ended December 31, 2012. Interest payments, and any other income, were retained within the portfolio and added to each Trust Series’ NAV. At the same time, each Trust Series incurred expenses for its management fee, brokerage commissions and other expenses (including ongoing registration fees). The calculation of each Applicable Index includes an interest portion, calculated daily using the 90-Day U.S. Treasury Bill’s total return, but does not include an expense component. When a Trust Series’ income exceeds the sum of its expenses by the yield on the 90-Day U.S. Treasury Bill, such Trust Series realizes a net yield that tends to cause daily changes in the per unit NAV of such Trust Series to track slightly higher than daily changes in the price of the Applicable Index. If this net yield is lower than the yield on the 90-Day U.S. Treasury Bill, that tends to cause daily changes in the per unit NAV of such Trust Series to track slightly lower than daily changes in the price of the Applicable Index. During the year ended December 31, 2012, USCI earned, on an annualized basis, approximately 0.07% on its cash holdings. It also incurred cash expenses on an annualized basis of 0.95% for management fees, approximately 0.07% in brokerage commission costs related to the purchase and sale of Futures Contracts, and approximately 0.13% for other expenses. The foregoing fees and expenses resulted in a net yield on an annualized basis of approximately (1.08)% and affected USCI’s ability to track its benchmark. During the year ended December 31, 2012, CPER earned, on an annualized basis, approximately 0.06% on its cash holdings. It also incurred cash expenses on an annualized basis of approximately 0.78%* for management fees, approximately 0.04% in brokerage commission costs related to the purchase and sale of Futures Contracts, and approximately 0.16% for other net expenses. The foregoing fees and expenses resulted in a net yield on an annualized basis of approximately (0.92)% and affected CPER’s ability to track its benchmark. During the period ended December 31, 2012, USAG earned, on an annualized basis, approximately 0.07% on its cash holdings. It also incurred cash expenses on an annualized basis of approximately 0.83%* for management fees, approximately 0.12% in brokerage commission costs related to the purchase and sale of Futures Contracts, and approximately 0.16% for other net expenses. The foregoing fees and expenses resulted in a net yield on an annualized basis of approximately (1.04)% and affected USAG’s ability to track its benchmark. During the period ended December 31, 2012, USMI earned, on an annualized basis, approximately 0.08% on its cash holdings. It also incurred cash expenses on an annualized basis of approximately 0.70%* for management fees, approximately 0.05% in brokerage commission costs related to the purchase and sale of Futures Contracts, and approximately 0.16% for other net expenses. The foregoing fees and expenses resulted in a net yield on an annualized basis of approximately (0.83)% and affected USMI’s ability to track its benchmark. If short-term interest rates rise above the current levels, the level of deviation created by the yield would decrease. Conversely, if short-term interest rates were to decline, the amount of error created by the yield would increase. When short-term yields drop to a level lower than the combined expenses of the management fee and the brokerage commissions, then the tracking error becomes a negative number and would tend to cause the daily returns of the per unit NAV to underperform the daily returns of the Applicable Index. USCF anticipates that interest rates will continue to remain at historical lows and therefore, it is anticipated that fees and expenses paid by each Trust Series will continue to be higher than interest earned by each Trust Series. As such, USCF anticipates that each Trust Series will continue to underperform tracking the Applicable Index until such a time when interest earned at least equals or exceeds the fees and expenses paid by each Trust Series.

* Effective as of May 29, 2012 (and continuing at least through March 31, 2013), USCF voluntarily waived the management fee paid by each of CPER and USAG from 0.95% to 0.65% and 0.80% per annum of average daily total net assets, respectively. Effective as of May 30, 2012 (and continuing at least through March 31, 2013), USCF voluntarily waived the management fee paid by USMI from 0.95% to 0.70% per annum of average daily total net assets. The reduced fee for USMI became operational as of June 19, 2012, the date USMI became listed on the NYSE Arca.

98

Third, a Trust Series may hold Futures Contracts in a particular commodity other than the one specified as the Applicable Benchmark Component Futures Contract, or may hold Other Related Investments in its portfolio that may fail to closely track the Applicable Index’s total return movements. Taking USCI as an example, assume for a given month one of the Benchmark Component Futures Contracts is the NYMEX WTI physically settled Futures Contract, trading under the symbol “CL,” for the contract month of November 2013. It is possible that USCI could hold a NYMEX WTI financially settled Futures Contract, trading under the symbol “WS,” for the contract month of November 2013. Alternatively, and using the same example, USCI could hold the ICE WTI financially settled Futures Contract, also for the contract month of November 2013. As a third example, USCI could hold the NYMEX WTI physically settled Futures Contract, trading under the symbol “CL,” but for a contract month other than November 2013.

Finally, a Trust Series could hold Other Related Investments. In any of these cases, the error in tracking the Applicable Index could result in daily changes in the per unit NAV of a Trust Series that are either too high, or too low, relative to the daily changes in the price of the Applicable Index. During the year ended December 31, 2012, none of the Trust Series held any Other Related Investments, but did, at times and for short holding periods, hold Futures Contracts that were in months other than the months specified as the Applicable Benchmark Component Futures Contract. If any Trust Series increases in size, and due to its obligations to comply with regulatory limits or due to other market pricing or liquidity factors, such Trust Series may invest in Futures Contract months other than the designated month specified as the Applicable Benchmark Component Futures Contract, or in Other Related Investments, which may have the effect of increasing transaction related expenses and may result in increased tracking error.

The table and chart below show the hypothetical performance of the Commodity Index from December 31, 2002 through December 31, 2012.

HYPOTHETICAL PERFORMANCE RESULTS HAVE MANY INHERENT LIMITATIONS, SOME OF WHICH ARE DESCRIBED BELOW. NO REPRESENTATION IS BEING MADE THAT USCI 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.

99

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.

USCF HAS HAD LITTLE OR NO EXPERIENCE IN TRADING ACTUAL ACCOUNTS FOR INVESTORS. BECAUSE THERE ARE NO ACTUAL TRADING RESULTS TO COMPARE TO THE HYPOTHETICAL PERFORMANCE RESULTS, INVESTORS SHOULD BE PARTICULARLY WARY OF PLACING UNDUE RELIANCE ON THESE HYPOTHETICAL PERFORMANCE RESULTS.

Since the Commodity Index was launched on December 18, 2009, there is only actual performance history of the Commodity Index from that date to the present. This data is available for periods prior to December 18, 2009. However, the components of the Commodity Index and the weighting of the components of the Commodity Index are established each month based on purely quantitative data that is not subject to revision based on other external factors. As a result, the table below reflects how the Commodity Index would have performed from December 31, 2002 through December 31, 2012 had it been in effect during such time period. The performance data does not reflect any reinvestment or distribution of profits, commission charges, management fees or other expenses that would have been incurred in connection with operating and managing a commodity pool designed to track the Commodity Index. Such fees and expenses would reduce the performance returns shown in the table below.

The table immediately above shows the performance of the Commodity Index from December 31, 1997 through December 31, 2012 in comparison with three traditional commodities indices: the S&P GSCI Commodity Index (GSCI^®) Total Return, Dow Jones-UBS Commodity Index Total Return^SM, and the Deutsche Bank Liquid Commodity Index-Optimum Yield Total Return^TM. The S&P GSCI^® Commodity Index Total Return is a composite index of commodity sector returns representing an unleveraged, long-only investment in commodity futures that is broadly diversified across the spectrum of commodities. The Dow Jones-UBS Commodity Index Total Return^SM is currently composed of futures contracts on a diversified basket of commodities traded on U.S. exchanges. The Deutsche Bank Liquid Commodity Index-Optimum Yield Total Return^TM is designed to reflect the performance of certain wheat, corn, light sweet crude oil, heating oil, gold and aluminum futures contracts plus the returns from investing in 3-month U.S. Treasury Bills. The data for the SDCI Total Return Index is derived by using the Commodity Index’s calculation methodology with historical prices for the futures contracts comprising the Commodity Index. The information about each of the indices comes from publicly-available material about such indices but is not designed to provide a thorough overview of the methodology of each index.

101

None of the indices has an investment objective identical to the Commodity Index. As a result, there are inherent limitations in comparing the performance of such indices against the Commodity Index. For more information about these indices and their methodologies, please refer to the material published by the sponsors of each such index which may be found on their websites. USCI is not responsible for any information found on such websites, and such information is not part of this annual report on Form 10-K.

In the table above, “Total Return” refers to the return of the relevant index from December 31, 1997 to December 31, 2012; “Annualized Volatility” is a measure of the amount of variation or fluctuation in the returns of the relevant index. Annualized Volatility is calculated by taking the monthly standard deviation of the relevant index’s return and multiplying it by the square root of 12; and “Annualized Sharpe Ratio” is a measure of the total return of each relevant index adjusted by the risk-free interest rate (the 90-Day U.S. Treasury Bill yield) and the volatility of each index. Many investors consider volatility to be a measure of risk, and lower volatility of investment returns is considered a positive investment attribute as opposed to higher volatility. Annualized Sharpe Ratio is a standard measure for investors to compare two different investments or indexes that have different levels of volatility. If two indexes have the same total return, but one has lower Annualized Volatility, then its Annualized Sharpe Ratio will be higher. The higher the Annualized Sharpe Ratio, the better the risk-adjusted performance. Annualized Sharpe Ratio is calculated by taking the average monthly total return of the relevant index and subtracting the then current yield on the 90-Day U.S. Treasury Bill. The annualized return of this series is then divided by the Annualized Volatility of this series, and this result is the Annualized Sharpe Ratio for the relevant index. A higher Sharpe Ratio is not a guarantee that one investment or index will in the future produce better risk adjustment total returns, but USCF believes it is a useful tool for investors to consider when making investment decisions.

The table above shows the performance of the Copper Index from December 31, 1997 through December 31, 2012 in comparison with a traditional commodity index and spot copper prices: the Dow Jones-UBS Copper Subindex Total Return^SM and spot copper prices less warehouse storage rents. The Dow Jones-UBS Copper Subindex Total Return^SM includes the contract in the Dow Jones-UBS Commodity Index Total Return that relates to a single commodity, copper (currently the Copper High Grade futures contract traded on the COMEX). The data for the SCI Total Return Index is derived by using the Copper Index’s calculation methodology with historical prices for the futures contracts comprising the Copper Index. The information about the index above comes from publicly-available material about such index but is not designed to provide a thorough overview of the methodology of such index. The index noted above does not have investment objectives identical to the Copper Index. As a result, there are inherent limitations in comparing such performance against the Copper Index.

The table and chart below show the hypothetical performance of the Agriculture Index from December 31, 2002 through December 31, 2012.

HYPOTHETICAL PERFORMANCE RESULTS HAVE MANY INHERENT LIMITATIONS, SOME OF WHICH ARE DESCRIBED BELOW. NO REPRESENTATION IS BEING MADE THAT USAG 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.

USCF HAS HAD LITTLE OR NO EXPERIENCE IN TRADING ACTUAL ACCOUNTS FOR ITSELF OR FOR INVESTORS. BECAUSE THERE ARE NO ACTUAL TRADING RESULTS TO COMPARE TO THE HYPOTHETICAL PERFORMANCE RESULTS, INVESTORS SHOULD BE PARTICULARLY WARY OF PLACING UNDUE RELIANCE ON THESE HYPOTHETICAL PERFORMANCE RESULTS.

Since the Agriculture Index was launched on September 23, 2010, there is only actual performance history of the Agriculture Index from that date to the present. However, the components of the Agriculture Index and the weighting of the components of the Agriculture Index are established each month based on purely quantitative data that is not subject to revisions based on other external factors. This data is available for periods prior to September 23, 2010. As a result, the table below reflects how the Agriculture Index would have performed from December 31, 2002 through December 31, 2012 had it been in effect during such time period. The performance data does not reflect any reinvestment or distribution of profits, commission charges, management fees or other expenses that would have been incurred in connection with operating and managing a commodity pool designed to track the Agriculture Index. Such fees and expenses would reduce the performance returns shown in the table below.

Hypothetical Performance Results for the period

from December 31, 2002 through December 31, 2012

Year	Ending Level*		Annual Return
2002		179.705		19.48	%

Hypothetical Total Returns (12/31/97-12/31/12)

PAST PERFORMANCE IS NOT NECESSARILY INDICATIVE OF FUTURE RESULTS

The following table and chart compare the hypothetical total return of the Agriculture Index in comparison with the actual total return of three major indexes from December 31, 1997 through December 31, 2012.

	Hypothetical and Historical Results for the period from December 31, 1997 through December 31, 2012
	DJ-UBS Ag TR		S&P GSCI Ag TR		DB LCI OY Ag TR		SDAI TR
Total return		(7)%		(42)%		26%		67%

Annualized volatility		20.39%		21.65%		19.92%		15.84%
Annualized Sharpe ratio		(0.05)		(0.19)		0.02		0.13

The table above shows the performance of the Agriculture Index from December 31, 1997 through December 31, 2012 in comparison with three traditional agricultural commodities indices: the S&P GSCI^® Agriculture Index Total Return, Dow Jones-UBS Agriculture Total Return Sub-index^SM, and the Deutsche Bank Liquid Commodity Index-Optimum Yield Agriculture Total Return^TM. The S&P GSCI^® Agriculture Index Total Return comprises the commodities: Wheat (Chicago and Kansas), Corn, Soybeans, Cotton, Sugar, Coffee, and Cocoa, and is part of a series of sub-indices representing components of the S&P GSCI. The Dow Jones-UBS Agriculture Total Return Sub-Index^SM is currently composed of seven futures contracts on agricultural commodities traded on U.S. exchanges. The Deutsche Bank Liquid Commodity Index-Optimum Yield Agriculture Total Return^TM is designed to reflect the performance of certain corn, wheat, soybean and sugar futures contracts plus the returns from investing in 3 month U.S. Treasury Bills. The data for the SDAI Total Return Index is derived by using the Agriculture Index’s calculation methodology with historical prices for the futures contracts comprising the Agriculture Index. The information about each of the indices comes from publicly-available material about such indices but is not designed to provide a thorough overview of the methodology of each index. None of the indices have investment objectives identical to the Agriculture Index. As a result, there are inherent limitations in comparing the performance of such indices against the Agriculture Index. For more information about these indices and their methodologies, please refer to the material published by the sponsors of each such index which may be found on their websites. USAG is not responsible for any information found on such website, and such information is not part of this annual report on Form 10-K.

In the table above, “Total Return” refers to the return of the relevant index from December 31, 1997 through December 31, 2012; “Annualized Volatility” is a measure of the amount of variation or fluctuation in the returns of the relevant index. Annualized Volatility is calculated by taking the monthly standard deviation of the relevant index’s return and multiplying it by the square root of 12; and “Annualized Sharpe Ratio” is a measure of the total return of each relevant index adjusted by the risk-free interest rate (the 90 Day U.S. Treasury Bill yield) and the volatility of each index. Many investors consider volatility to be a measure of risk, and lower volatility of investment returns is considered a positive investment attribute as opposed to higher volatility. Annualized Sharpe Ratio is a standard measure for investors to compare two different investments or indexes that have different levels of volatility. If two indexes have the same total return, but one has lower Annualized Volatility, then its Annualized Sharpe Ratio will be higher. The higher the Annualized Sharpe Ratio, the better the risk-adjusted performance. Annualized Sharpe Ratio is calculated by taking the average monthly total return of the relevant index and subtracting the then current yield on the 90 Day U.S. Treasury Bill. The annualized return of this series is then divided by the Annualized Volatility of this series, and this result is the Annualized Sharpe Ratio for the relevant index. A higher Sharpe Ratio is not a guarantee that one investment or index will in the future produce better risk adjustment total returns, but USCF believes it is a useful tool for investors to consider when making investment decisions.

The table above shows the performance of the Metals Index from December 31, 1997 through December 31, 2012 in comparison with three traditional metals indices: the Rogers International Commodity Index^®–Metals Total Return, Dow Jones-UBS Industrial Metals Total Return Sub-index^SM, and the Deutsche Bank Liquid Commodity Index-Optimum Yield Industrial Metals Total Return^TM. The Rogers International Commodity Index^®–Metals Total Return is an index of ten metals commodity futures contracts, representing commodities consumed in the global economy and is a sub-index of the Rogers International Commodity Index. The Dow Jones-UBS Industrial Metals Total Return Sub-Index^SM is currently composed of four futures contracts on industrial metals, three of which (aluminum, nickel and zinc) are traded on the LME and the other of which (copper) is traded on the COMEX division of the NYMEX. The Deutsche Bank Liquid Commodity Index-Optimum Yield Industrial Metals Total Return^TM is designed to reflect the performance of certain futures contracts on aluminum, copper and zinc. The data for the SDMI Total Return Index is derived by using the Metals Index’s calculation methodology with historical prices for the futures contracts comprising the Metals Index. The information about each of the indices comes from publicly-available material about such indices but is not designed to provide a thorough overview of the methodology of each index. None of the indices have investment objectives identical to the Metals Index. As a result, there are inherent limitations in comparing the performance of such indices against the Metals Index. For more information about these indices and their methodologies, please refer to the material published by the sponsors of each such index which may be found on their websites. USMI is not responsible for any information found on such websites, and such information is not part of this annual report on Form 10-K.

In the table above, “Total Return” refers to the return of the relevant index from December 31, 1997 to December 31, 2012; “Annualized Volatility” is a measure of the amount of variation or fluctuation in the returns of the relevant index. Annualized Volatility is calculated by taking the monthly standard deviation of the relevant index’s return and multiplying it by the square root of 12; and “Annualized Sharpe Ratio” is a measure of the total return of each relevant index adjusted by the risk-free interest rate (the 90 Day U.S. Treasury Bill yield) and the volatility of each index. Many investors consider volatility to be a measure of risk, and lower volatility of investment returns is considered a positive investment attribute as opposed to higher volatility.

If two indexes have the same total return, but one has lower Annualized Volatility, then its Annualized Sharpe Ratio will be higher. The higher the Annualized Sharpe Ratio, the better the risk-adjusted performance. Annualized Sharpe Ratio is calculated by taking the average monthly total return of the relevant index and subtracting the then current yield on the 90 Day U.S. Treasury Bill. The annualized return of this series is then divided by the Annualized Volatility of this series, and this result is the Annualized Sharpe Ratio for the relevant index. A higher Sharpe Ratio is not a guarantee that one investment or index will in the future produce better risk adjustment total returns, but USCF believes it is a useful tool for investors to consider when making investment decisions.

PAST PERFORMANCE IS NOT NECESSARILY INDICATIVE OF FUTURE RESULTS

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

119

Liquidity and Capital Resources

None of the Trust Series has made, and does not anticipate making, use of borrowings or other lines of credit to meet its obligations. Each Trust Series has met, and it is anticipated that each Trust Series 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. Each Trust Series’ liquidity needs include: redeeming units, providing margin deposits for its existing Futures Contracts or the purchase of additional Futures Contracts and posting collateral for its over-the-counter Applicable Interests, respectively, if applicable, and, except as noted below, payment of its expenses, summarized below under “Contractual Obligations.”

Each Trust Series currently generates cash primarily from: (i) the sale of Creation Baskets and (ii) income earned on Treasuries, cash and/or cash equivalents. Each Trust Series has allocated substantially all of its net assets to trading in Applicable Interests. Each Trust Series invests in Applicable 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 Applicable Interests. A significant portion of each Trust Series’ NAV is held in Treasuries, cash and cash equivalents that are used as margin and as collateral for its trading in Applicable Interests. The balance of the assets is held in each Trust Series’ account at the Custodian and in Treasuries at the FCM. Income received from any investments in money market funds and Treasuries by a Trust Series will be paid to such Trust Series. During the years ended December 31, 2012 and 2011 and the period ended December 31, 2010, USCI’s expenses exceeded the income it earned and the cash earned from the sale of Creation Baskets and the redemption of Redemption Baskets. During the year ended December 31, 2012 and the period ended December 31, 2011, CPER’s expenses exceeded the income it earned and the cash earned from the sale of Creation Baskets. During the period from April 13, 2012 to December 31, 2012, USAG’s expenses exceeded the income it earned and the cash it earned from the sale of Creation Baskets. During the period from June 19, 2012 to December 31, 2012, USMI’s expenses exceeded the income it earned and the cash earned from the sale of Creation Baskets. During the years ended December 31, 2012 and 2011 and the period ended December 31, 2010, USCI was forced to use other assets to pay expenses, which could cause a drop in its NAV over time. During the year ended December 31, 2012 and the period ended December 31, 2011, CPER was forced to use other assets to pay expenses, which could cause a drop in its NAV over time. During the period from April 13, 2012 to December 31, 2012, USAG was forced to use other assets to pay expenses, which could cause a drop in its NAV over time. During the period from June 19, 2012 to December 31, 2012, USMI was forced to use other assets to pay expenses, which could cause a drop in its NAV over time. To the extent expenses exceed income, each Trust Series’ NAV will be negatively impacted.

Each Trust Series’ investments in Applicable 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 contract 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 a Trust Series from promptly liquidating its positions in Futures Contracts. During the year ended December 31, 2012, none of the Trust Series was forced to purchase or liquidate any of its positions while daily limits were in effect; however, no Trust Series can predict whether such an event may occur in the future.

Prior to the initial offering of each Trust Series, all payments with respect to each Trust Series’ expenses are paid by USCF. None of the Trust Series has an obligation or intention to refund such payments made by USCF. USCF is under no obligation to pay any Trust Series’ future expenses. Since the initial offering of units, each Trust Series has been responsible for expenses relating to: (i) management fees, (ii) brokerage fees and commissions, (iii) ongoing registration expenses in connection with offers and sales of its units subsequent to the initial offering, (iv) other expenses, including tax reporting costs, (v) the fees of the Trustee in connection with its services as Delaware trustee of the Trust, (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 the Trust Series’ Marketing Agent, Administrator and Custodian, the trading advisory and licensing fees of SummerHaven and offering expenses relating to the initial offering of units of each Trust Series. If USCF and each Trust Series are unsuccessful in raising sufficient funds to cover these respective expenses or in locating any other source of funding, one or more of the Trust Series could terminate and investors may lose all or part of their investment.

120

Market Risk

Trading in Applicable Interests such as Futures Contracts involves each Trust Series entering into contractual commitments to purchase or sell specified amounts of commodities at a specified date in the future. The aggregate market value of the contracts will significantly exceed each Trust Series’ future cash requirements since each Trust Series intends to close out its open positions prior to settlement. As a result, each Trust Series is generally only subject to the risk of loss arising from the change in value of the contracts. Each Trust Series considers the “fair value” of its derivative instruments to be the unrealized gain or loss on the contracts. The market risk associated with each Trust Series’ commitments to purchase a specific commodity will be limited to the aggregate market value of the contracts held.

Each Trust Series’ exposure to market risk depends on a number of factors, including the markets for commodities, the volatility of interest rates and foreign exchange rates, the liquidity of the Applicable Interest markets and the relationships among the contracts held by each such Trust Series. The limited experience that each Trust Series has had in utilizing its model to trade in Applicable Interests in a manner intended to track the changes in the Applicable Index, as well as drastic market occurrences, could ultimately lead to the loss of all or substantially all of an investor’s capital.

Credit Risk

When a Trust Series enters into Futures Contracts and Other Related Investments, it is exposed to the credit risk that the counterparty will not be able to meet its obligations. The counterparty for the Futures Contracts traded on the 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. Unlike in the case of exchange-traded Futures Contracts, the counterparty to an over-the-counter contract is generally a single bank or other financial institution. As a result, there will be greater counterparty credit risk in over-the-counter transactions. There can be no assurance that any counterparty, clearinghouse, or their members or their financial backers will satisfy their obligations to a Trust Series in such circumstances.

USCF attempts to manage the credit risk of each Trust Series by following various trading limitations and policies. In particular, each Trust Series generally posts margin and/or holds liquid assets that are approximately equal to the market value of its obligations to counterparties under the Futures Contracts and Other Related Investments it holds. USCF has implemented procedures that include, but are not limited to, executing and clearing trades and entering into over-the-counter transactions only with creditworthy parties and/or requiring the posting of collateral or margin by such parties for the benefit of each Trust Series to limit its credit exposure. Newedge, each Trust Series’ commodity broker, or any other broker that may be retained by a Trust Series in the future, when acting as the Trust Series’ FCM in accepting orders to purchase or sell Futures Contracts on United States exchanges, is required by CFTC regulations to separately account for and segregate as belonging to a Trust Series, all assets of a Trust Series relating to domestic Futures Contracts trading. These FCMs are not allowed to commingle a Trust Series’ assets with their other assets. In addition, the CFTC requires commodity brokers to hold in a secure account a Trust Series’ assets related to foreign Futures Contracts trading. During the year ended December 31, 2012, the only foreign exchanges on which USCI made investments were the ICE Futures, which is a London based futures exchange, and the LME, which is a London based metal commodities exchange. Those Futures Contracts are denominated in U.S. dollars. During the year ended December 31, 2012, CPER did not make investments on any foreign exchanges. During the year ended December 31, 2012, the only foreign exchange on which USAG made investments was the ICE Futures. Those Futures Contracts are denominated in Canadian dollars and U.S. dollars. During the year ended December 31, 2012, the only foreign exchange on which USMI made investments was the LME. Those Futures Contracts are denominated in U.S. dollars.

If, in the future, a Trust Series 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, 2012, each of USCI, CPER, USAG and USMI held cash deposits and investments in Treasuries in the amount of $491,119,704, $2,541,590, $2,679,845 and $2,605,049, respectively, with the Custodian and FCM. Some or all of these amounts may be subject to loss should the Trust Series’ Custodian and/or FCM cease operations.

121

Off Balance Sheet Financing

As of December 31, 2012, neither the Trust nor any Trust Series had any loan guarantee, credit support or other off-balance sheet arrangement 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 any Trust Series. While each Trust Series’ exposure under these indemnification provisions cannot be estimated, they are not expected to have a material impact on any Trust Series’ financial position.

European Sovereign Debt

None of the Trust Series had direct exposure to European sovereign debt as of December 31, 2012 or had 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, each Trust Series requires liquidity to redeem units, which redemptions must be in blocks of 50,000 units effective as of May 1, 2012 called “Redemption Baskets.” (Prior to May 1, 2012, the size of the Redemption Basket was 100,000 units). Each Trust Series has to date satisfied this obligation by paying from the cash or cash equivalents it holds or through the sale of its Treasuries in an amount proportionate to the number of units being redeemed. From July 1, 2011 through May 1, 2013, Authorized Purchasers pay USCI $350 for each order placed to create one or more Creation Baskets or to redeem one or more Redemption Baskets; prior to July 1, 2011, Authorized Purchasers paid USCI $1,000 for each order placed to create one or more Creation Baskets or to redeem one or more Redemption Baskets. From May 1, 2012 through May 1, 2013, Authorized Purchasers pay each of CPER, USAG and USMI $350 for each order placed to create one or more Creation Baskets or to redeem one or more Redemption Baskets; prior to May 1, 2012, Authorized Purchasers paid $1,000 for each order placed to create one or more Creation Baskets or to redeem one or more Redemption Baskets.

Contractual Obligations

The Trust’s (and each series thereunder) primary contractual obligations are with USCF and certain other service providers. USCF, in return for its services, is entitled to a management fee calculated as a fixed percentage of a Trust Series’ NAV. Effective as of May 29, 2012 (and continuing at least through March 31, 2013), USCF voluntarily waived the management fee paid by each of CPER and USAG from 0.95% to 0.65% and 0.80% per annum of average daily total net assets, respectively. Effective as of May 30, 2012 (and continuing at least through March 31, 2013), USCF voluntarily waived the management fee paid by USMI from 0.95% to 0.70% per annum of average daily total net assets. The reduced fee for USMI became operational as of June 19, 2012, the date USMI became listed on the NYSE Arca. Ongoing fees, costs and expenses of its operation for which a Trust Series is responsible include:

• brokerage and other fees and commissions incurred in connection with the trading activities of each Trust Series;

• expenses incurred in connection with registering additional units of each Trust Series or offering units of each Trust Series after the time any units of each Trust Series have begun trading on the NYSE Arca;

• the routine expenses associated with distribution, including printing and mailing, of any monthly, annual and other reports to unitholders required by applicable U.S. federal and state regulatory authorities;

• payment for routine services of the Trustee, legal counsel and independent accountants;

• payment for fees associated with tax accounting and reporting, routine accounting, bookkeeping, whether performed by an outside service provider or by affiliates of USCF;

• costs and expenses associated with investor relations and services;

• the payment of any distributions related to redemption of units;

• payment of all federal, state, local or foreign taxes payable on the income, assets or operations of each Trust Series and the preparation of all tax returns related thereto;

• fees and expenses of the independent directors of USCF; and

• extraordinary expenses (including, but not limited to, indemnification of any person against liabilities and obligations to the extent permitted by law and required under the Trust Agreement 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 expense and the settlement of claims and litigation).

122

While USCF has agreed to pay registration fees to the SEC, FINRA, NYSE Arca or any other regulatory agency or exchange in connection with the initial offer and sale of the units and the legal, printing, accounting and other expenses associated with such registration, each Trust Series is responsible for any registration fees and related expenses incurred in connection with any subsequent offer and sale of its units after the initial offering of units.

Each Trust Series pays its own brokerage and other transaction costs. Each Trust Series pays fees to FCMs in connection with its transactions in Futures Contracts. For the year ended December 31, 2012, FCM fees were approximately 0.07% of average daily total net assets for USCI, approximately 0.04% of average daily total net assets for CPER, approximately 0.12% of average daily total net assets for USAG and approximately 0.05% of average daily total net assets for USMI. In general, transaction costs on over-the-counter Applicable Interests and on Treasuries and other short-term securities are embedded in the purchase or sale price of the instrument being purchased or sold, and may not readily be estimated. USCF had voluntarily agreed to pay certain expenses normally borne by USCI to the extent that such expenses exceeded 0.15% (15 basis points) of USCI’s NAV, on an annualized basis, through March 31, 2011. As of March 31, 2011, the expense waiver was no longer in effect for USCI. USCF has voluntarily agreed to pay certain expenses normally borne by each of CPER, USAG and USMI to the extent that such expenses exceed 0.15% (15 basis points) of each of CPER’s, USAG’s and USMI’s NAV, on an annualized basis, through at least June 30, 2013. USCF has no obligation to continue such payments into subsequent periods. This voluntary expense waiver is in addition to those amounts USCF is contractually obligated to pay as described in Note 5.

The parties cannot anticipate the amount of payments that will be required under these arrangements for future periods, as each Trust Series’ 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 a Trust Series’ existence. Either party may terminate these agreements earlier for certain reasons described in the agreements.

As of December 31, 2012, USCI’s portfolio consisted of 13,041 Futures Contracts traded on the Futures Exchanges, CPER’s portfolio consisted of 28 Futures Contracts traded on the COMEX, USAG’s portfolio consisted of 72 Futures Contracts traded on the Futures Exchanges and USMI’s portfolio consisted of 84 Futures Contracts traded on the Futures Exchanges. For a list of each of USCI’s, CPER’s, USAG’s and USMI’s current holdings, please see USCI’s website at www.unitedstatescommodityindexfund.com, CPER’s website at www.unitedstatescopperindexfund.com, USAG’s website at www.unitedstatesagricultureindexfund.com and USMI’s website at www.unitedstatesmetalsindexfund.com. See “Portfolio Holdings” for a complete list of Futures Contracts held by each of USCI, CPER, USAG and USMI during the year ended December 31, 2012.

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

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

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

Swap transactions, like other financial transactions, involves 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 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 a Trust Series’ obligations or its exposure to the risks associated with a transaction prior to its scheduled termination date.

123

To reduce the credit risk that arises in connection with such contracts, a Trust Series 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 the Trust Series due to the occurrence of a specified event, such as the insolvency of the counterparty.

A Trust Series 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 a Trust Series 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. A Trust Series 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 year ended December 31, 2012, none of the Trust Series employed any hedging methods such as those described above since all of its investments were made over an exchange. Therefore, during such period, none of the Trust Series’ was exposed to counterparty risk.

Each Trust Series anticipates that the use of Other Related Investments together with its investments in Futures Contracts will produce price and total return results that closely track the investment goals of such Trust Series. 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 Futures Contracts, which may impact a Trust Series’ ability to successfully track its Applicable Index.

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

USCF assessed the effectiveness of the Trust’s and each Trust Series’ internal control over financial reporting as of December 31, 2012. In making this assessment, it used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control Integrated Framework. Based on the assessment, USCF believes that, as of December 31, 2012, the internal control over financial reporting for the Trust and each Trust Series is effective.

Auditors’ Report on Internal Control over Financial Reporting

To the Sponsor of

United States Commodity Index Funds Trust

We have audited the internal control over financial reporting of the United States Commodity Index Funds Trust (the “Trust”), the United States Commodity Index Fund, the United States Copper Index Fund, the United States Agriculture Index Fund and the United States Metals Index Fund (collectively, the “Series”) as of December 31, 2012, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. The Trust’s and the Series’ 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 Trust’s and the Series’ 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 Trust and the Series maintained, in all material respects, effective internal control over financial reporting as of December 31, 2012, 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, 2012, of the Trust and the Series and our report dated March 13, 2013 expressed an unqualified opinion on those financial statements.

Report of Independent Registered Public Accounting Firm

To the Sponsor of

United States Commodity Index Funds Trust

We have audited the accompanying statements of financial condition of the United States Commodity Index Funds Trust (the “Trust”), the United States Commodity Index Fund, the United States Copper Index Fund, the United States Agriculture Index Fund and the United States Metals Index Fund (collectively, the “Series”), in total and for the Series as of December 31, 2012 and 2011, including the schedule of investments as of December 31, 2012 and 2011, and the related statements of operations, changes in capital and changes in units outstanding and cash flows for the years ended December 31, 2012, 2011 and 2010. These financial statements are the responsibility of the Trust’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of the United States Commodity Index Funds Trust, the United States Commodity Index Fund, the United States Copper Index Fund, the United States Agriculture Index Fund and the United States Metals Index Fund as of December 31, 2012 and 2011, and the results of their operations and their cash flows for the years ended December 31, 2012, 2011 and 2010, in conformity with accounting principles generally accepted in the United States of America.

We also have audited, in accordance with standards of the Public Company Accounting Oversight Board (United States), the Trust’s and the Series’ internal control over financial reporting as of December 31, 2012, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated March 13, 2013 expressed an unqualified opinion on the Trust’s and the Series’ internal control over financial reporting.

The Trust is a series trust formed pursuant to the Delaware Statutory Trust Act and includes the United States Commodity Index Fund (“USCI”), a commodity pool formed on April 1, 2010 and first made available to the public on August 10, 2010, the United States Copper Index Fund (“CPER”), a commodity pool formed on November 26, 2010 and first made available to the public on November 15, 2011, the United States Agriculture Index Fund (“USAG”), a commodity pool formed on November 26, 2010 and first made available to the public on April 13, 2012 and the United States Metals Index Fund (“USMI”), a commodity pool formed on November 26, 2010 and first made available to the public on June 19, 2012. USCI, CPER, USAG and USMI each issues units (“units”) that may be purchased and sold on the NYSE Arca, Inc. (the “NYSE Arca”). USCI, CPER, USAG and USMI are collectively referred to herein as the “Trust Series.” The Trust and each Trust Series operate pursuant to the Second Amended and Restated Declaration of Trust and Trust Agreement dated as of November 10, 2010 (the “Trust Agreement”). United States Commodity Funds LLC (“USCF”) is the sponsor of the Trust and the Trust Series and is also responsible for the management of the Trust and the Trust Series. For purposes of the financial statement presentation, unless specified otherwise, all references will be to the Trust Series.

USCF has the power and authority to establish and designate one or more series and to issue units thereof, from time to time as it deems necessary or desirable. USCF has exclusive power to fix and determine the relative rights and preferences as between the units of any series as to right of redemption, special and relative rights as to dividends and other distributions and on liquidation, conversion rights, and conditions under which the series shall have separate voting rights or no voting rights. The term for which the Trust is to exist commenced on the date of the filing of the Certificate of Trust, and the Trust and any Trust Series will exist in perpetuity, unless earlier terminated in accordance with the provisions of the Trust Agreement. Separate and distinct records must be maintained for each Trust Series and the assets associated with a Trust Series must be held in such separate and distinct records (directly or indirectly, including a nominee or otherwise) and accounted for in such separate and distinct records separately from the assets of any other Trust Series. Each Trust Series is separate from all other Trust Series created as series of the Trust in respect of the assets and liabilities allocated to that Trust Series and represents a separate investment portfolio of the Trust.

The sole Trustee of the Trust is Wilmington Trust Company (the “Trustee”), a Delaware banking corporation. The Trustee is unaffiliated with USCF. The Trustee’s duties and liabilities with respect to the offering of units and the management of the Trust are limited to its express obligations under the Trust Agreement.

USCF is a member of the National Futures Association (the “NFA”) and became a commodity pool operator (“CPO”) registered with the Commodity Futures Trading Commission (the “CFTC”) effective December 1, 2005. The Trust and each Trust Series have a fiscal year ending on December 31.

USCF is also the general partner of the United States Oil Fund, LP (“USOF”), the United States Natural Gas Fund, LP (“USNG”), the United States 12 Month Oil Fund, LP (“US12OF”), the United States Gasoline Fund, LP (“UGA”) and the United States Diesel-Heating Oil Fund, LP (formerly, the United States Heating Oil Fund, LP) (“USDHO”), which listed their limited partnership units on the American Stock Exchange (the “AMEX”) under the ticker symbols “USO” on April 10, 2006, “UNG” on April 18, 2007, “USL” on December 6, 2007, “UGA” on February 26, 2008 and “UHN” on April 9, 2008, respectively. As a result of the acquisition of the AMEX by NYSE Euronext, each of USOF’s, USNG’s, US12OF’s, UGA’s and USDHO’s units commenced trading on the NYSE Arca on November 25, 2008. USCF is also the general partner of the United States Short Oil Fund, LP (“USSO”), the United States 12 Month Natural Gas Fund, LP (“US12NG”) and the United States Brent Oil Fund, LP (“USBO”), which listed their limited partnership units on the NYSE Arca under the ticker symbols “DNO” on September 24, 2009, “UNL” on November 18, 2009 and “BNO” on June 2, 2010, respectively. All funds listed previously are referred to collectively herein as the “Related Public Funds.” USCF has also filed registration statements to register units of the United States Sugar Fund (“USSF”), the United States Natural Gas Double Inverse Fund (“UNGD”), the United States Gasoil Fund (“USGO”) and the United States Asian Commodities Basket Fund (“UAC”), each a series of the United States Commodity Funds Trust I, and the US Golden Currency Fund (“HARD”), a series of the United States Currency Funds Trust.

157

Effective as of May 1, 2012, each of USCI, CPER and USAG issue units to certain authorized purchasers (“Authorized Purchasers”) by offering baskets consisting of 50,000 units (“Creation Baskets”) through ALPS Distributors, Inc., as the marketing agent (the “Marketing Agent”). Prior to May 1, 2012, each of USCI, CPER and USAG issued units to Authorized Purchasers by offering baskets consisting of 100,000 units through the Marketing Agent. USMI was not available to the public until June 19, 2012, and from its inception of offering, issues units to certain Authorized Purchasers by offering baskets consisting of 50,000 units through the Marketing Agent. The purchase price for a Creation Basket is based upon the net asset value (“NAV”) of a unit calculated shortly after the close of the core trading session on the NYSE Arca on the day the order to create the basket is properly received.

From July 1, 2011 through May 1, 2013, Authorized Purchasers pay USCI $350 for each order placed to create one or more Creation Baskets or to redeem one or more baskets (“Redemption Baskets”), consisting of 50,000 units; prior to July 1, 2011, Authorized Purchasers paid USCI $1,000 for each order placed to create one or more Creation Baskets or to redeem one or more Redemption Baskets. From May 1, 2012 through May 31, 2013, Authorized Purchasers pay each of CPER, USAG and USMI $350 for each order placed to create one or more Creation Baskets or to redeem one or more Redemption Baskets; prior to May 1, 2012, Authorized Purchasers paid $1,000 for each order placed to create one or more Creation Baskets or to redeem one or more Redemption Baskets. Units may be purchased or sold on a nationally recognized securities exchange in smaller increments than a Creation Basket or Redemption Basket. Units purchased or sold on a nationally recognized securities exchange are not purchased or sold at the per unit NAV of each Trust Series but rather at market prices quoted on such exchange.

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. Each Trust Series earns interest on its assets denominated in U.S. dollars on deposit with the futures commission merchant at the 90-day Treasury bill rate. In addition, each Trust Series earns income on funds held at the custodian and/or futures commission merchant at prevailing market rates earned on such investments.

Brokerage Commissions

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

Income Taxes

The Trust Series are not subject to federal income taxes; each investor 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”), each Trust Series 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. Each Trust Series files an income tax return in the U.S. federal jurisdiction, and may file income tax returns in various U.S. states. None of the Trust Series is subject to income tax return examinations by major taxing authorities for years before 2010 (year of the Trust Series’ inception, but not necessarily the commencement of operations for each Trust Series). 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 each Trust Series recording a tax liability that reduces net assets. However, each Trust Series’ 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. Each Trust Series 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, 2012 for any Trust Series.

158

Trust Capital and Allocation of Income and Losses

Profit or loss shall be allocated among the unitholders of each Trust Series in proportion to the number of units each investor holds as of the close of each month. USCF may revise, alter or otherwise modify this method of allocation as described in the Trust Agreement.

Adoption of New Monthly Allocation Convention

Effective January 1, 2012, USCI adopted a new convention for allocating items of income, gain, loss, deduction and credits. In situations where a partner’s interest in a partnership is sold or otherwise transferred during a taxable year, the Code generally requires that partnership tax items for the year be allocated among the partners using either an interim closing of the books or a daily proration method. USCI uses an interim closing of the books method under which income, gains and losses (both realized and unrealized), deductions and credits are determined on a monthly basis. Prior to January 1, 2012, USCI allocated these tax items among the holders of the units (including those who dispose of units during a taxable year) in proportion to the number of units owned by them on the last trading day of each month. For this purpose, if an investor holds a unit as of the close of business of the last trading day of a particular month, such investor is treated as if it owned the unit throughout the month and thus is allocated all of the items of income, gain, deduction, loss or credit attributable to that unit for such month (the “same-month convention”).

Effective January 1, 2012 for USCI, November 15, 2011 for CPER, April 13, 2012 for USAG and June 19, 2012 for USMI, an allocation convention is applied pursuant to which each Trust Series’ tax items for each month will be allocated among the holders of units in proportion to the number of units owned by them as of the close of business of the last trading day of the previous month. If an investor who holds a unit as of the close of business on the last trading day of the previous month disposes of a unit during the current month, such investor will be treated for purposes of making allocations as if it owned the unit throughout the current month (the “next-month convention”). For example, an investor who buys a unit on April 10 of a year and sells it on May 20 of the same year will be allocated all of the tax items attributable to May (because he or she is deemed to hold it through the last day of May) but will not be allocated any of the tax items attributable to April. The tax items attributable to that unit for April will be allocated to the person who is the actual or deemed holder of the unit as of the close of business on the last trading day of March.

For investors in USCI, as a result of the transition from the same-month convention to the next-month convention, an investor who bought a unit in December 2011 and sold the unit on or after January 1, 2012 will be allocated the tax items attributable to that unit for December 2011 as well as the tax items attributable to that unit for 2012.

Creations and Redemptions

Authorized Purchasers may purchase Creation Baskets or redeem Redemption Baskets only in blocks of 50,000 units. Effective as of May 1, 2012, Authorized Purchasers may purchase Creation Baskets or redeem Redemption Baskets for USCI, CPER and USAG only in blocks of 50,000 units at a price equal to the NAV of the units calculated shortly after the close of the core trading session on the NYSE Arca on the day the order is placed. Prior to May 1, 2012, Authorized Purchasers could only purchase Creation Baskets or redeem Redemption Baskets for USCI, CPER and USAG in blocks of 100,000 units. USMI was not available to the public until June 19, 2012, and from its inception of offering, Authorized Purchasers could only purchase Creation Baskets in blocks of 50,000 units.

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

Calculation of Net Asset Value Per Unit

Each Trust Series’ per unit NAV is calculated on each NYSE Arca trading day by taking the current market value of its total assets, subtracting any liabilities and dividing the amount by the total number of units issued and outstanding. Each Trust Series uses the closing prices on the relevant Futures Exchanges (as defined in Note 3 below) of the Applicable Benchmark Component Futures Contracts (as defined in Note 3 below) that at any given time make up the Applicable Index (as defined in Note 3 below) (determined at the earlier of the close of such exchange or 2:30 p.m. New York time) for the contracts traded on the Futures Exchanges, but calculates or determines the value of all other investments of each Trust Series using market quotations, if available, or other information customarily used to determine the fair value of such investments.

159

Net Income (Loss) Per Unit

Net income (loss) per unit is the difference between the per unit NAV at the beginning of each period and the per unit NAV at the end of each period. The weighted average number of units outstanding was computed for purposes of disclosing net income (loss) per weighted average unit. The weighted average units are equal to the number of units outstanding at the end of the period, adjusted proportionately for units added and redeemed based on the amount of time the units were outstanding during such period. As of December 31, 2012, USCF held 50,000 units of USMI.

Offering Costs

Offering costs incurred in connection with the registration of units prior to the commencement of the offering are borne by USCF. Offering costs incurred in connection with the registration of additional units after the commencement of the offering are borne by each Trust Series. These costs include registration fees paid to regulatory agencies and all legal, accounting, printing and other expenses associated with such offerings. Costs borne by the Trust Series after the commencement of an offering 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.

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.

Reclassification

The audited financial statements for the year ended December 31, 2010 have been adjusted to reflect a non-material capital contribution of cash from USCF in the amount of $3,000. The $3,000 capital contribution was received by the Trust from USCF on November 10, 2010.

NOTE 3 - TRUST SERIES

In connection with the execution of the First Trust Agreement on April 1, 2010, USCI was designated as the first series of the Trust. USCF contributed $1,000 to the Trust upon its formation on December 21, 2009, representing an initial contribution of capital to the Trust. Following the designation of USCI as the first series of the Trust, the initial capital contribution of $1,000 was transferred from the Trust to USCI and deemed an initial contribution to USCI. In connection with the commencement of USCI’s initial offering of units, USCF received 20 Sponsor Units of USCI in exchange for the previously received capital contribution, representing a beneficial ownership interest in USCI.

On July 30, 2010, USCI received a notice of effectiveness from the U.S. Securities and Exchange Commission (the “SEC”) for its registration of 50,000,000 units on Form S-1 with the SEC. On August 10, 2010, USCI listed its units on the NYSE Arca under the ticker symbol “USCI”. USCI established its initial per unit NAV by setting the price at $50.00 and issued 100,000 units in exchange for $5,000,000 on August 10, 2010. USCI also commenced investment operations on August 10, 2010 by purchasing Futures Contracts traded on the Futures Exchanges. In order to satisfy NYSE Arca listing standards that at least 100,000 units be outstanding at the beginning of the trading day on the NYSE Arca, USCF purchased the initial Creation Basket from the initial Authorized Purchaser at the initial offering price. The $1,000 fee that would otherwise be charged to the Authorized Purchaser in connection with an order to create or redeem was waived in connection with the initial Creation Basket. USCF held such initial Creation Basket until September 3, 2010, at which time the initial Authorized Purchaser repurchased the units comprising such basket in accordance with the specified conditions noted above. On September 14, 2011, USCF redeemed the 20 Sponsor Units of USCI and, on September 19, 2011, USCF purchased five units of USCI in the open market.

160

In connection with the Second Amended and Restated Trust Agreement dated November 10, 2010, USMI, USAG and CPER were designated as three additional series of the Trust. Following the designation of the additional series, an initial capital contribution of $3,000 was transferred from USCF to the Trust. On November 10, 2010, the Trust transferred $1,000 to each of USMI, USAG and CPER, which was deemed a capital contribution to each series. On November 14, 2011, USCF received 40 Sponsor Units of CPER in exchange for the previously received capital contribution, representing a beneficial interest in CPER. On December 7, 2011, USCF redeemed the 40 Sponsor Units of CPER and purchased 40 units of CPER in the open market. On April 13, 2012, USCF received 40 Sponsor Units of USAG in exchange for the previously received capital contribution, representing a beneficial interest in USAG. On June 28, 2012, USCF redeemed the 40 Sponsor Units of USAG and on October 3, 2012, purchased 5 units of USAG on the open market. On June 19, 2012, USCF received 40 Sponsor Units of USMI in exchange for the previously received capital contribution, representing a beneficial interest in USMI. On August 27, 2012, USCF redeemed the 40 Sponsor Units of USMI.

CPER, USAG and USMI received notice of effectiveness from the SEC for its registration of 30,000,000 CPER units, 20,000,000 USAG units and 20,000,000 USMI units on September 6, 2011. The order to permit listing CPER, USAG and USMI on the NYSE Arca was received on October 20, 2011. On November 15, 2011, CPER listed its units on the NYSE Arca under the ticker symbol “CPER.” CPER established its initial per unit NAV by setting the price at $25.00 and issued 100,000 units to the initial authorized purchaser, Merrill Lynch Professional Clearing Corp., in exchange for $2,500,000 in cash on November 15, 2011. The $1,000 fee that would otherwise be charged to the Authorized Purchaser in connection with an order to create or redeem was waived in connection with the initial Creation Basket.

On April 13, 2012, USAG listed its units on the NYSE Arca under the ticker symbol “USAG.” USAG established its initial per unit NAV by setting the price at $25.00. On April 14, 2012, USCF purchased 2 initial Creation Baskets of USAG. In accordance with applicable requirements of Regulation M under the Securities Exchange Act of 1934, no Creation Baskets were offered to Authorized Purchasers nor were the units listed on the NYSE Arca until five business days had elapsed from the date of USCF’s purchase of the initial Creation Basket on April 4, 2012. The $1,000 fee that would have otherwise been charged in connection with an order to create or redeem was waived in connection with the initial Creation Basket.

On June 19, 2012, USMI listed its units on the NYSE Arca under the ticker symbol “USMI.” USMI established its initial per unit NAV by setting the price at $25.00. On June 11, 2012, USCF purchased two initial Creation Baskets of USMI. In accordance with applicable requirements of Regulation M under the Securities Exchange Act of 1934, no Creation Baskets were offered to Authorized Purchasers nor were the units listed on the NYSE Arca until five business days had elapsed from the date of USCF’s purchase of the initial Creation Basket on June 11, 2012. The $350 fee that would have otherwise been charged in connection with an order to create or redeem was waived in connection with the initial Creation Basket. On August 29, 2012, USCF redeemed one of two initial Creation Baskets of USMI, leaving its holdings to 50,000 units.

USCI’s Investment Objective

USCI invests in futures contracts for commodities that are currently traded on the New York Mercantile Exchange (the “NYMEX”), ICE Futures (“ICE Futures”), Chicago Board of Trade (“CBOT”), Chicago Mercantile Exchange (“CME”), London Metal Exchange (“LME”), Commodity Exchange, Inc. (“COMEX”) or on other foreign exchanges (the NYMEX, ICE Futures, CBOT, CME, LME, Comex and other foreign exchanges, collectively, the “Futures Exchanges”) (such futures contracts, collectively, “Futures Contracts”) and, to a lesser extent, in order to comply with regulatory requirements or in view of market conditions, other commodity-based contracts and instruments such as cash-settled options on Futures Contracts, forward contracts relating to commodities, cleared swap contracts and other non exchange traded (“over-the-counter”) transactions that are based on the price of commodities and Futures Contracts (collectively, “Other Commodity-Related Investments”). Market conditions that USCF currently anticipates could cause USCI to invest in Other Commodity Related Investments would be those allowing USCI to obtain greater liquidity or to execute transactions with more favorable pricing. Futures Contracts and Other Commodity-Related Investments collectively are referred to as “Commodity Interests.”

The investment objective of USCI is for the daily changes in percentage terms of its units’ per unit net asset value (“NAV”) to reflect the daily changes in percentage terms of the SummerHaven Dynamic Commodity Index Total Return^SM (the “Commodity Index”), less USCI’s expenses. USCF does not intend to operate USCI in a fashion such that its per unit NAV will equal, in dollar terms, the spot prices of the commodities underlying the Benchmark Component Futures Contracts (as defined below) that comprise the Commodity Index or the prices of any particular group of Futures Contracts. USCI will not seek to achieve its stated investment objective over a period of time greater than one day. USCI believes that it is not practical to manage the portfolio to achieve such an investment goal when investing in Futures Contracts and Other Commodity-Related Investments. The Commodity Index is designed to reflect the performance of a diversified group of commodities. The Commodity Index is comprised of 14 Futures Contracts that are selected on a monthly basis from a list of 27 possible Futures Contracts. The Futures Contracts that at any given time make up the Commodity Index are referred to herein as “Benchmark Component Futures Contracts.” The Commodity Index is owned and maintained by SummerHaven Index Management, LLC (“SummerHaven Indexing”) and calculated and published by Bloomberg, L.P. USCI invests first in the current Benchmark Component Futures Contracts and other Futures Contracts intended to replicate the return on the current Benchmark Component Futures Contracts and, thereafter may hold Futures Contracts in a particular commodity other than one specified as the Benchmark Component Futures Contract, or may hold Other Commodity-Related Investments that are intended to replicate the return on the Benchmark Futures Contracts, but may fail to closely track the Commodity Index’s total return movements. If USCI increases in size, and due to its obligations to comply with regulatory limits or due to other market pricing or liquidity factors, USCI may invest in Futures Contract months other than the designated month specified as the Benchmark Component Futures Contract, or in Other Commodity-Related Investments, which may have the effect of increasing transaction related expenses and may result in increased tracking error.

161

USCI’s units began trading on August 10, 2010. As of December 31, 2012, USCI held 1,058 Futures Contracts on the NYMEX, 2,240 Futures Contracts on the ICE Futures, 3,405 Futures Contracts on the CBOT, 637 Futures Contracts on the CME, 5,701 Futures Contracts on the LME and did not hold any Futures Contracts on the COMEX.

CPER’s Investment Objective

The investment objective of CPER is for the daily changes in percentage terms of its units’ per unit NAV to reflect the daily changes in percentage terms of the SummerHaven Copper Index Total Return^SM (the “Copper Index”), less CPER’s expenses. USCF does not intend to operate CPER in a fashion such that its per unit NAV will equal, in dollar terms, the spot prices of the commodities underlying the Benchmark Component Copper Futures Contracts (as defined below) that comprise the Copper Index or the prices of any particular group of Futures Contracts. CPER will not seek to achieve a stated investment objective over a period of time greater than one day. USCF believes that it is not practical to manage the portfolio to achieve such an investment goal when investing in Futures Contracts and Other Copper-Related Investments (as defined below). The Copper Index is designed to reflect the performance of the investment returns from a portfolio of copper futures contracts. The Copper Index is owned and maintained by SummerHaven Indexing and calculated and published by the NYSE Arca. The Copper Index is comprised of either two or three Eligible Copper Futures Contracts that are selected on a monthly basis based on quantitative formulas relating to the prices of the Eligible Copper Futures Contracts developed by SummerHaven Indexing. The Eligible Copper Futures Contracts that at any given time make up the Copper Index are referred to herein as “Benchmark Component Copper Futures Contracts.”

CPER seeks to achieve its investment objective by investing to the fullest extent possible in the Benchmark Component Copper Futures Contracts. Then, if constrained by regulatory requirements or in view of market conditions, CPER will invest next in other Eligible Copper Futures Contracts, and finally to a lesser extent, in other exchange traded futures contracts that are economically identical or substantially similar to the Benchmark Component Copper Futures Contracts if one or more other Eligible Copper Futures Contracts is not available. When CPER has invested to the fullest extent possible in exchange-traded futures contracts, CPER may then invest in other contracts and instruments based on the Benchmark Component Copper Futures Contracts, other Eligible Copper Futures Contracts or copper, such as cash-settled options, forward contracts, cleared swap contracts and swap contracts other than cleared swap contracts. Other exchange-traded futures contracts that are economically identical or substantially similar to the Benchmark Component Copper Futures Contracts and other contracts and instruments based on the Benchmark Component Copper Futures Contracts, are collectively referred to collectively as “Other Copper-Related Investments,” and together with Benchmark Component Copper Futures Contracts and other Eligible Copper Futures Contracts, “Copper Interests.” CPER’s units began trading on November 15, 2011. As of December 31, 2012, CPER held 28 Futures Contracts on the COMEX.

USAG’s Investment Objective

The investment objective of USAG is for the daily changes in percentage terms of its units’ per unit NAV to reflect the daily changes in percentage terms of the SummerHaven Dynamic Agriculture Index Total Return^SM (the “Agriculture Index”), less USAG’s expenses. USCF does not intend to operate USAG in a fashion such that its per unit NAV will equal, in dollar terms, the spot prices of the commodities underlying the Benchmark Component Agriculture Futures Contracts (as defined below) that comprise the Agriculture Index or the prices of any particular group of Futures Contracts. USAG will not seek to achieve its stated investment objective over a period of time greater than one day. USCF believes that it is not practical to manage the portfolio to achieve such an investment goal when investing in Futures Contracts and Other Agriculture-Related Investments (as defined below). The Agriculture Index is designed to reflect the performance of a diversified group of agricultural commodities. The Agriculture Index is owned and maintained by SummerHaven Indexing and calculated and published by the NYSE Arca. Futures contracts for the agricultural commodities comprising the Agriculture Index are traded on ICE Future US, ICE Futures Canada, the CBOT, the Kansas City Board of Trade (“KCBT”) and the CME and are collectively referred to herein as “Eligible Agriculture Futures Contracts.” The Agriculture Index is comprised of 14 Eligible Agriculture Futures Contracts that are selected on a monthly basis based on quantitative formulas developed by SummerHaven Indexing. The Eligible Agriculture Futures Contracts that at any given time make up the Agriculture Index are referred to herein as “Benchmark Component Agriculture Futures Contracts.” The relative weighting of the Benchmark Component Agriculture Futures Contracts will change on a monthly basis, based on quantitative formulas relating to the prices of the Benchmark Component Agriculture Futures Contracts developed by SummerHaven Indexing.

162

USAG seeks to achieve its investment objective by investing to the fullest extent possible in the Benchmark Component Agriculture Futures Contracts. Then, if constrained by regulatory requirements or in view of market conditions, USAG will invest next in other Eligible Agriculture Futures Contracts based on the same agricultural commodity as the futures contracts subject to such regulatory constraints or market conditions, and finally, to a lesser extent, in other exchange traded futures contracts that are economically identical or substantially similar to the Benchmark Component Agriculture Futures Contracts if one or more other Eligible Agriculture Futures Contracts is not available. When USAG has invested to the fullest extent possible in exchange-traded futures contracts, USAG may then invest in other contracts and instruments based on the Benchmark Component Agriculture Futures Contracts, other Eligible Agriculture Futures Contracts or the agricultural commodities included in the Agriculture Index, such as cash-settled options, forward contracts, cleared swap contracts and swap contracts other than cleared swap contracts. Other exchange-traded futures contracts that are economically identical or substantially similar to the Benchmark Component Agriculture Futures Contracts and other contracts and instruments based on the Benchmark Component Agriculture Futures Contracts, as well as metals included in the Agriculture Index, are collectively referred to as “Other Agriculture-Related Investments,” and together with Benchmark Component Agriculture Futures Contracts and other Eligible Agriculture Futures Contracts, “Agriculture Interests.” USAG’s units began trading on April 13, 2012. As of December 31, 2012, USAG held 29 Futures Contracts on the ICE Futures, 9 Futures Contracts on the CME, 4 Futures Contracts on the KCBT and 30 Futures Contracts on the CBOT.

USMI’s Investment Objective

The investment objective of USMI is for the daily changes in percentage terms of its units’ per unit NAV to reflect the daily changes in percentage terms of the SummerHaven Metals Index Total Return^SM (the “Metals Index”), less USMI’s expenses. USCF does not intend to operate USMI in a fashion such that its per unit NAV will equal, in dollar terms, the spot prices of the commodities underlying the Benchmark Component Metals Futures Contracts (as defined below) that comprise the Metals Index or the prices of any particular group of Futures Contracts. USMI will not seek to achieve its stated investment objective over a period of time greater than one day. USCF believes that it is not practical to manage the portfolio to achieve such an investment goal when investing in Futures Contracts and Other Metals-Related Investments (as defined below). The Metals Index is owned and maintained by SummerHaven Indexing and calculated and published by the NYSE Arca. Futures contracts for the metals in the Metals Index that are traded on the NYMEX, the LME and COMEX are collectively referred to herein as “Eligible Metals Futures Contracts.” The Metals Index is comprised of 10 Eligible Metals Futures Contracts that are selected on a monthly basis based on quantitative formulas developed by SummerHaven Indexing. The Eligible Metals Futures Contracts that at any given time make up the Metals Index are referred to herein as “Benchmark Component Metals Futures Contracts.” The relative weighting of the Benchmark Component Metals Futures Contracts will change on a monthly basis, based on quantitative formulas relating to the prices of the Benchmark Component Metals Futures Contracts developed by SummerHaven Indexing.

USMI seeks to achieve its investment objective by investing to the fullest extent possible in the Benchmark Component Metals Futures Contracts. Then, if constrained by regulatory requirements or in view of market conditions, USMI will invest next in other Eligible Metals Futures Contracts, and finally to a lesser extent, in other exchange traded futures contracts that are economically identical or substantially similar to the Benchmark Component Metals Futures Contracts if one or more other Eligible Metals Futures Contracts is not available. When USMI has invested to the fullest extent possible in exchange-traded futures contracts, USMI may then invest in other contracts and instruments based on the Benchmark Component Metals Futures Contracts, other Eligible Metals Futures Contracts or the metals included in the Metals Index, such as cash-settled options, forward contracts, cleared swap contracts and swap contracts other than cleared swap contracts. Other exchange-traded futures contracts that are economically identical or substantially similar to the Benchmark Component Metals Futures Contracts and other contracts and instruments based on the Benchmark Component Metals Futures Contracts are collectively referred to as “Other Metals-Related Investments,” and together with Benchmark Component Metals Futures Contracts and other Eligible Metals Futures Contracts, “Metals Interests.” USMI’s units began trading on June 19, 2012. As of December 31, 2012, USMI held 2 Futures Contracts on the NYMEX, 1 Futures Contract on the CME, 70 Futures Contracts on the LME and 11 Futures Contracts on the COMEX.

NOTE 4 - FEES PAID BY USCI and CPER AND RELATED PARTY TRANSACTIONS

USCF Management Fee

Under the Trust Agreement, USCF is responsible for investing the assets of each Trust Series in accordance with the objectives and policies of each such Trust Series. In addition, USCF has arranged for one or more third parties to provide trading advisory, administrative, custody, accounting, transfer agency and other necessary services to each Trust Series. For these services, each of USCI, CPER, USAG and USMI is contractually obligated to pay USCF a fee, which is paid monthly, equal to 0.95% per annum of average daily total net assets. Effective as of May 29, 2012 (and continuing at least through March 31, 2013), USCF voluntarily waived the management fee paid by each of CPER and USAG from 0.95% per annum of average daily total net assets to 0.65% and 0.80% per annum of average daily total net assets, respectively. Effective as of May 30, 2012 (and continuing at least through March 31, 2013), USCF voluntarily waived the management fee paid by USMI from 0.95% per annum of average daily total net assets to 0.70% per annum of average daily total net assets. The reduced fee for USMI became operational as of June 19, 2012, when USMI first became listed on the NYSE Arca.

Trustee Fee

The Trustee is the Delaware trustee of the Trust. In connection with the Trustee’s services, USCF is responsible for paying the Trustee’s annual fee in the amount of $3,000.

Ongoing Registration Fees and Other Offering Expenses

Each Trust Series pays the costs and expenses associated with the ongoing registration of its units subsequent to the initial offering. These costs include registration or other fees paid to regulatory agencies in connection with the offer and sale of units, and all legal, accounting, printing and other expenses associated with such offer and sale. During the years ended December 31, 2012, 2011 and 2010, none of the Trust Series incurred any registration fees or other offering expenses.

164

Directors’ Fees and Expenses

Each Trust Series is responsible for paying its portion of the directors’ and officers’ liability insurance for such Trust Series and the Related Public Funds. In addition, as of July 8, 2011, each Trust Series is responsible for paying the fees and expenses of the independent directors who also serve as audit committee members of the Trust Series and the Related Public Funds organized as limited partnerships. Each Trust Series shares the fees and expenses on a pro rata basis with each other Trust Series and 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, 2012 amounted to a total of $540,586 for the Trust Series and the Related Public Funds. USCI’s portion of such fees and expenses for the year ended December 31, 2012 was $68,533, CPER’s portion of such fees and expenses for the year ended December 31, 2012 was $415. USAG’s portion of such fees and expenses for the year ended December 31, 2012 was $220 and USMI’s portion of such fees and expenses for the year ended December 31, 2012 was $154.

Investor Tax Reporting Cost

The fees and expenses associated with each Trust Series’ audit expenses and tax accounting and reporting requirements are paid by such Trust Series. These costs amounted to a total of $300,000 for the year ended December 31, 2012 for USCI, $50,000 for the year ended December 31, 2012 for CPER, $75,000 for the year ended December 31, 2012 for USAG and $75,000 for the year ended December 31, 2012 for USMI.

Other Expenses and Fees and Expense Waivers

In addition to the fees described above, each Trust Series pays all brokerage fees and other expenses in connection with the operation of such Trust Series, excluding costs and expenses paid by USCF as outlined in Note 5 below. USCF had voluntarily agreed to pay certain expenses normally borne by USCI to the extent that such expenses exceeded 0.15% (15 basis points) of USCI’s NAV, on an annualized basis, through March 31, 2011. As of March 31, 2011, the expense waiver for USCI was no longer in effect. In addition, USCF has voluntarily agreed to pay certain expenses normally borne by each of CPER, USAG and USMI to the extent that such expenses exceed 0.15% (15 basis points) of each of CPER’s, USAG’s and USMI’s NAV, on an annualized basis, through at least June 30, 2013. USCF has no obligation to continue such payments into subsequent periods. For the year ended December 31, 2012, USCF waived $96,364 in expenses for CPER, $76,851 for USAG and $59,316 for USMI. This voluntary expense waiver is in addition to those amounts USCF is contractually obligated to pay as described in Note 5.

NOTE 5 - CONTRACTS AND AGREEMENTS

USCF and the Trust, each on its own behalf and on behalf of each Trust Series, are party to a marketing agent agreement, dated as of July 22, 2010, as amended from time to time, with the Marketing Agent, whereby the Marketing Agent provides certain marketing services for each Trust Series as outlined in the agreement. The fee of the Marketing Agent, which is borne by USCF, is equal to 0.06% on each Trust Series’ assets up to $3 billion and 0.04% on each Trust Series’ assets in excess of $3 billion.

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

USCF and the Trust, on its own behalf and on behalf of each Trust Series, are also party to a custodian agreement, dated July 22, 2010, as amended from time to time, with Brown Brothers Harriman & Co. (“BBH&Co.”), whereby BBH&Co. holds investments on behalf of each Trust Series. USCF pays the fees of the custodian, which are determined by the parties from time to time. In addition, USCF and the Trust, on its own behalf and on behalf of each Trust Series, are party to an administrative agency agreement, dated July 22, 2010, as amended from time to time, with BBH&Co., whereby BBH&Co. acts as the administrative agent, transfer agent and registrar for each Trust Series. 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 each Trust Series 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 USCI’s, CPER’s, USAG’s, USMI’s, USOF’s, USNG’s, US12OF’s, UGA’s, USDHO’s, USSO’s, US12NG’s and USBO’s combined net assets, (b) 0.0465% for USCI’s, CPER’s, USAG’s, USMI’s, USOF’s, USNG’s, US12OF’s, UGA’s, USDHO’s, USSO’s, US12NG’s and USBO’s combined net assets greater than $500 million but less than $1 billion, and (c) 0.035% once USCI’s, CPER’s, USAG’s, USMI’s, USOF’s, USNG’s, US12OF’s, UGA’s, USDHO’s, USSO’s, US12NG’s and USBO’s combined net assets exceed $1 billion. The annual minimum amount will not apply if the asset-based charge for all accounts in the aggregate exceeds $75,000. USCF also pays transaction fees ranging from $7 to $15 per transaction.

165

Each Trust Series has entered into a brokerage agreement, dated March 1, 2010 for USCI and November 18, 2011 for each of CPER, USAG and USMI, as amended from time to time, with Newedge USA, LLC (“Newedge”). The agreement requires Newedge to provide services to each Trust Series in connection with the purchase and sale of Futures Contracts and Other Related Investments that may be purchased and sold by or through Newedge for each Trust Series’ account. In accordance with the agreement, Newedge charges each Trust Series commissions of approximately $7 to $15 per round-turn trade, including applicable exchange and NFA fees for Futures Contracts and options on Futures Contracts. Such fees include those incurred when purchasing Futures Contracts and options on Futures Contracts when each Trust Series issues units as a result of a Creation Basket, as well as fees incurred when selling Futures Contacts and options on Futures Contracts when each Trust Series redeems units as a result of a Redemption Basket. Such fees are also incurred when Futures Contracts and options on Futures Contracts are purchased or redeemed for the purpose of rebalancing the portfolio. Each Trust Series also incurs commissions to brokers for the purchase and sale of Futures Contracts, Other Commodity-Related Investments or Treasuries. During the year ended December 31, 2012, total commissions accrued to brokers amounted to $310,109 for USCI. Of this amount, approximately $296,759 was a result of rebalancing costs and approximately $13,350 was the result of trades necessitated by creation and redemption activity for USCI. By comparison, during the year ended December 31, 2011, total commissions accrued to brokers amounted to $307,284 for USCI. Of this amount, approximately $286,584 was a result of rebalancing costs and approximately $20,700 was the result of trades necessitated by creation and redemption activity for USCI. By comparison, during the year ended December 31, 2010, total commissions accrued to brokers amounted to $23,632. Of this amount, approximately $18,532 was a result of rebalancing costs and approximately $5,100 was the result of trades necessitated by creation and redemption activity for USCI. The increase in the total commissions accrued to brokers by USCI for the year ended December 31, 2012 as compared to the year ended December 31, 2011 was primarily due to an increase in USCI’s total net assets for the year ended December 31, 2012. The increase in the total commissions accrued to brokers by USCI for the year ended December 31, 2011 as compared to the year ended December 31, 2010, was primarily a function of an increase in USCI’s total net assets for the year ended December 31, 2011 and the fact that USCI was operating for only a portion of the year ended December 31, 2010 versus a full year of operations for the year ended December 31, 2011. As an annualized percentage of average total net assets, USCI’s figure for the year ended December 31, 2012 represents approximately 0.07% of USCI’s average total net assets. By comparison, USCI’s figure for the year ended December 31, 2011 represented approximately 0.08% of USCI’s average total net assets and the figure for the period ended December 31, 2010 represented approximately 0.15% of USCI’s 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.

During the year ended December 31, 2012, total commissions accrued to brokers amounted to $956 for CPER. Of this amount, approximately $799 was a result of rebalancing costs and approximately $157 was the result of trades necessitated by creation and redemption activity. By comparison, during the year ended December 31, 2011, total commissions paid to brokers amounted to $177 for CPER. Of this amount, approximately $45 was a result of rebalancing costs and approximately $132 was the result of trades necessitated by creation and redemption activity for CPER. The increase in CPER’s total commissions accrued to brokers for the year ended December 31, 2012 as compared to the year ended December 31, 2011, was primarily due an increase in CPER’s total net assets for the year ended December 31, 2012 and that CPER was operating for only a portion of the year ended December 31, 2011 versus a full year of operations for the year ended December 31, 2012. As an annualized percentage of average total net assets, CPER’s figure for the year ended December 31, 2012 represents approximately 0.04% of CPER’s average total net assets. By comparison, CPER’s figure for the year ended December 31, 2011 represented approximately 0.06% of CPER’s 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.

During the year ended December 31, 2012, total commissions accrued to brokers amounted to $2,632 for USAG. Of this amount, approximately $2,090 was a result of rebalancing costs and approximately $542 was the result of trades necessitated by creation and redemption activity. As an annualized percentage of average daily total net assets, USAG’s figure for the year ended December 31, 2012 represents approximately 0.12% of USAG’s average daily total net assets. However, there can be no assurance that commission costs and portfolio turnover will not cause commission expenses to rise in future quarters.

166

During the year ended December 31, 2012, total commissions accrued to brokers amounted to $714 for USMI. Of this amount, approximately $512 was a result of rebalancing costs and approximately $202 was the result of trades necessitated by creation and redemption activity. As an annualized percentage of average daily total net assets, USMI’s figure for the year ended December 31, 2012 represents approximately 0.05% of USMI’s average daily total net assets. However, there can be no assurance that commission costs and portfolio turnover will not cause commission expenses to rise in future quarters.

USCF is party to an Amended Advisory Agreement, dated July 1, 2011, as amended from time to time, with SummerHaven, whereby SummerHaven provides advisory services to USCF with respect to the Applicable Index for each Trust Series and investment decisions for each Trust Series. SummerHaven’s advisory services include, but are not limited to, general consultation regarding the calculation and maintenance of the Applicable Index for each Trust Series, anticipated changes to each Applicable Index and the nature of each Applicable Index’s current or anticipated component securities. For these services, USCF pays SummerHaven a fee based on a percentage of the average total net assets of each Trust Series. For USCI, the fee is equal to the percentage fees paid to USCF minus 0.14%, with that result multiplied by 0.5, minus 0.06% to arrive at the actual fee paid. For each of CPER, USAG and USMI, the fee is equal to the percentage fees paid to USCF minus 0.18%, with that result multiplied by 0.5, minus 0.6% to arrive at the actual fee paid.

USCF is also party to an Amended Licensing Agreement, dated July 1, 2011, as amended from time to time, with SummerHaven, whereby SummerHaven sub-licensed to each Trust Series the use of certain names and marks, including the Applicable Index for each Trust Series for which SummerHaven has a sub-license from SummerHaven Indexing, the owner of each Applicable Index. Under the Licensing Agreement, USCF paid SummerHaven an annual fee of $15,000 per each Trust Series for the year ended December 31, 2012, plus an annual fee of 0.06% of the average daily total net assets of each Trust Series.

NOTE 6 - FINANCIAL INSTRUMENTS, OFF-BALANCE SHEET RISKS AND CONTINGENCIES

Each Trust Series engages in the trading of futures contracts and options on futures contracts and may engage in cleared swaps (collectively, “derivatives”). As such, each Trust Series 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.

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

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

Futures contracts 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 each Trust Series 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.

All of the Futures Contracts held by each Trust Series were exchange-traded through December 31, 2012. The risks associated with exchange-traded contracts are generally perceived to be less than those associated with over-the-counter transactions since, in over-the-counter transactions, a party must rely solely on the credit of its respective individual counterparties. However, in the future, if each Trust Series were to enter into non-exchange traded contracts, it would be subject to the credit risk associated with counterparty non-performance. The credit risk from counterparty non-performance associated with such instruments is the net unrealized gain, if any, on the transaction. Currently, each Trust Series 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, each Trust Series bears the risk of financial failure by the clearing broker.

167

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

USCF may invest a portion of each Trust Series’ cash in money market funds that seek to maintain a stable per unit NAV. Each Trust Series may be exposed to any risk of loss associated with an investment in such money market funds. As of December 31, 2012 and December 31, 2011, none of the Trust Series held investments in money market funds. Each Trust Series 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, 2012 and December 31, 2011, USCI held cash deposits and investments in Treasuries in the amounts of $491,119,704 and $374,465,568, respectively, with the custodian and futures commission merchant. As of December 31, 2012 and December 31, 2011, CPER held cash deposits and investments in Treasuries in the amounts of $2,541,590 and $2,511,610, respectively, with the custodian and futures commission merchant. As of December 31, 2012 and December 31, 2011, USAG held cash deposits and investments in Treasuries in the amounts of $2,679,845 and $1,000, respectively, with the custodian and futures commission merchant. As of December 31, 2012 and December 31, 2011, USMI held cash deposits and investments in Treasuries in the amounts of $2,605,049 and $1,000, respectively, with the custodian and futures commission merchant. Some or all of these amounts may be subject to loss should the Trust Series’ custodian and/or futures commission merchant cease operations.

For derivatives, risks arise from changes in the market value of the contracts. Theoretically, each Trust Series 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, each Trust Series 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.

The Trust Series’ 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, the Trust Series or USCF have a policy of requiring review of the credit standing of each broker or counterparty with which they conduct business.

The financial instruments held by the applicable Trust Series are reported in its statements of financial condition at market or fair value, or at carrying amounts that approximate fair value, because of their highly liquid nature and short-term maturity.

NOTE 9 – FAIR VALUE OF FINANCIAL INSTRUMENTS

The Trust and each Trust Series value their 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 the Trust and each Trust Series (observable inputs) and (2) the Trust’s and each Trust Series’ 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 USCI’s securities at December 31, 2012 using the fair value hierarchy:

NOTE 10 – RECENT ACCOUNTING PRONOUNCEMENTS

In December 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2011-11, “Balance Sheet (Topic 210): Disclosures about Offsetting Assets and Liabilities.” The amendments in ASU No. 2011-11 require an entity to disclose information about offsetting and related arrangements to enable users of its financial statements to understand the effect of those arrangements on its financial position. ASU No. 2011-11 is effective for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods. The guidance requires retrospective application for all comparative periods presented. USCF is currently evaluating the impact ASU No. 2011-11 will have on the Trust’s and each Trust Series’ financial statements.

NOTE 11 – SUBSEQUENT EVENTS

The Trust and each Trust Series have performed an evaluation of subsequent events through the date the financial statements were issued. This evaluation did not result in any subsequent events that necessitated disclosures and/or adjustments.

177

Item 9. Changes in and Disagreements With Accountants on Accounting and Financial Disclosure.

Not applicable.

Item 9A. Controls and Procedures.

Disclosure Controls and Procedures

The Trust and each Trust Series maintain disclosure controls and procedures that are designed to ensure that material information required to be disclosed in the Trust’s periodic reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time period specified in the SEC’s rules and forms.

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

Management’s Annual Report on Internal Control Over Financial Reporting

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

Change in Internal Control Over Financial Reporting

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

Item 9B. Other Information.

Monthly Account Statements

Pursuant to the requirement under Rule 4.22 under the CEA, each month the Trust and each Trust Series publish account statements for the Trust Series’ unitholders, which include Statements of Income (Loss), Statements of Changes in Net Asset Value and Statements of Changes in Units Outstanding. The account statements are furnished to the SEC on a current report on Form 8-K pursuant to Section 13 or 15(d) of the Exchange Act and posted each month on each Trust Series’ website at www.unitedstatescommodityindexfund.com, www.unitedstatescopperindexfund.com, www.unitedstatesagricultureindexfund.com and www.unitedstatesmetalsindexfund.com.

Audit Committee

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

Other Committees

Since the individuals who perform work on behalf of each Trust Series are not compensated by such Trust Series, but instead by USCF, none of the Trust Series has a compensation committee. Similarly, since the directors noted above serve on the Board of USCF, there is no nominating committee of the Board that acts on behalf of any Trust Series. USCF believes that it is necessary for each member of the Board to possess many qualities and skills. USCF further believes that all directors should possess a considerable amount of business management and educational experience. There have not been any vacancies on USCF’s Board since the commencement of operations of USCI, the first Trust Series, in August 2010; however, if such a vacancy were to occur, the members of the Board would consider a candidate’s management experience as well as his/her background, stature, conflicts of interest, integrity and ethics. In connection with this, the Board would also consider issues of diversity, such as diversity of gender, race and national origin, education, professional experience and differences in viewpoints and skills. The Board does not have a formal policy with respect to diversity; however, the Board believes that it is essential that the Board members represent diverse viewpoints.

183

Corporate Governance Policy

The Board of USCF has adopted a Corporate Governance Policy that applies to each Trust Series and the Related Public Funds. Each of the Trust Series has posted the text of the Corporate Governance Policy on its website at www.unitedstatescommodityindexfund.com, www.unitedstatescopperindexfund.com, www.unitedstatesagricultureindexfund.com and www.unitedstatesmetalsindexfund.com, respectively. Any unitholder of the Trust Series’ may also obtain a printed copy of the Corporate Governance Policy, free of charge, by calling 1-800-920-0259.

Code of Ethics

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

Executive Sessions of the Non-Management Directors

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

Board Leadership Structure and Role in Risk Oversight

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

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

184

Risk Management

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

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

Other Information

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

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Exchange Act requires directors and executive officers of USCF and persons who are beneficial owners of at least 10% of a Trust Series’ units to file with the SEC an Initial Statement of Beneficial Ownership of Securities on Form 3 within 10 calendar days of first becoming a director, executive officer or beneficial owner of at least 10% of a Trust Series’ units and a Statement of Changes of Beneficial Ownership of Securities on Form 4 within 2 business days of a subsequent acquisition or disposition of units of a Trust Series. To each Trust Series’ knowledge, based upon a review of copies of reports furnished to it with respect to the fiscal year ended December 31, 2012 and upon the written representations of the directors and executive officers of USCF, all of such persons have filed all required reports.

185

Item 11. Executive Compensation.

Compensation to USCF and Other Compensation

None of the Trust Series directly compensates any of the executive officers noted above. The executive officers noted above are compensated by USCF for the work they perform on behalf of each Trust Series and other entities controlled by USCF. None of the Trust Series reimburses USCF for, nor does it set the amount or form of any portion of, the compensation paid to the executive officers by USCF. Each Trust Series pays fees to USCF pursuant to the Trust Agreement. Each of USCI, CPER, USAG and USMI is contractually obligated to pay USCF a fee, which is paid monthly, equal to 0.95% per annum of average daily total net assets. Effective as of May 29, 2012 (and continuing at least through March 31, 2013), USCF voluntarily waived the management fee paid by each of CPER and USAG from 0.95% per annum of average daily total net assets to 0.65% and 0.80% per annum of average daily total net assets, respectively. Effective as of May 30, 2012 (and continuing at least through March 31, 2013), USCF voluntarily waived the management fee paid by USMI from 0.95% per annum of average daily total net assets to 0.70% per annum of average daily total net assets. The reduced fee for USMI became operational as of June 19, 2012, when USMI first became listed on the NYSE Arca. For 2012, each of USCI, CPER, USAG and USMI accrued aggregate management fees of $4,070,144, $19,823, $17,492 and $10,681, respectively.

However, there have been no direct financial transactions between any Trust Series and the directors or officers of USCF that have not been disclosed herein. See “Item 11. Executive Compensation” and “Item 12. Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters.” Any transaction with a related person that must be disclosed in accordance with SEC Regulation S-K item 404(a), including financial transactions by any Trust Series with directors or executive officers of USCF or holders of beneficial interests in USCF or any Trust Series of more than 5%, will be subject to the provisions regarding “Fiduciary Duty” as set forth in Section 5.6 of the Trust Agreement and will be reviewed and approved by the audit committee of the Board of USCF.

Director Independence

In February 2013, the Board undertook a review of the independence of the directors of USCF and considered whether any director has a material relationship or other arrangement with USCF, the Trust Series or the Related Public Funds that could compromise his ability to exercise independent judgment in carrying out his responsibilities. As a result of this review, the Board determined that each of Messrs. Fobes, Ellis and Robinson is an “independent director,” as defined under the rules of NYSE Arca.

CODE OF BUSINESS CONDUCT AND ETHICS

Introduction

Ethics are important to United States Commodity Funds LLC (the “Company” or “USCF”) and to each member of our management, our investment professionals, and our employees. The Company is committed to the highest ethical standards and to conducting business with the highest level of integrity.

All officers, directors and employees of the Company are responsible for maintaining this level of integrity and for complying with the policies contained in this Code. If you have a question or concern about what is proper conduct for you or anyone else, please raise these concerns with any member of management, or follow the procedures outlined this Code.

Purpose of the Code

This Code is intended to:

• help you recognize ethical issues and take the appropriate steps to resolve these issues;

• deter ethical violations;

• assist you in reporting any unethical or illegal conduct; and

• reaffirm and promote our commitment to a corporate culture that values honesty and accountability.

All employees, as a condition of employment or continued employment, will acknowledge in writing that they have received a copy of this Code, read it, and understand that the Code contains our expectations regarding their conduct.

Finally, you should know that this Code is designed to satisfy the standards contained in the Federal Sentencing Guidelines for Organizations published by the U.S. Department of Justice. U.S. federal courts are bound to apply the Federal Sentencing Guidelines for Organizations when sentencing companies convicted of federal offenses arising from the illegal acts of one or more employees. The Federal Sentencing Guidelines for Organizations provide for substantial leniency in sentencing of a company from otherwise severe mandatory penalties, where the company had in effect an adequate compliance program at the time of the illegal activity.

1

Conflicts of Interest

You must avoid any conflict, or the appearance of a conflict, between your personal interests and our interests. A conflict exists when your personal interest in any way interferes with our interests, or when you take any action or have any interest that may make it difficult for you to perform your job objectively and effectively. For example, a conflict of interest probably exists if:

• you cause us to enter into business relationships with you or a member of your family, or invest in companies affiliated with you or a member of your family;

• you use for your personal gain, or the gain of a member of your family, any nonpublic information (i) about us, (ii) our affiliates, (iii) our service providers, (iv) our other business partners, (v) the statutory trusts for which the Company acts as sponsor, United States Commodity Index Funds Trust (the “Index Funds Trust”), United States Commodity Funds Trust I (“Trust I”) and United States Currency Funds Trust (“Currency Funds Trust” and together with “Trust I” and the “Index Funds Trust”, the “Trusts”) (vi) each of the funds for which the Company serves as general partner or series of the Trusts for which the Company serves as sponsor, (each a “Fund” and together the “Funds”); or

• you use or communicate confidential information obtained in the course of your work for your or another’s personal benefit.

Corporate Opportunities

Each of us has a duty to advance the legitimate interests of the Company when the opportunity to do so presents itself. Therefore, you may not:

• take for yourself personally opportunities, including investment opportunities, discovered through the use of your position with us, or through the use of our property or information;

• use our property, information, or position for your personal gain or the gain of a family member; or

• compete, or prepare to compete, with us.

Public Disclosure

We are committed to a policy of full, fair, accurate, timely, and understandable disclosure to unitholders of all material information regarding our business. This policy extends to our filings with the Securities and Exchange Commission (“SEC”) and to all other public communications. All individuals involved in our SEC reporting process and in preparing and making public communications regarding our business must take all reasonable steps to comply with this policy.

2

Confidentiality

You must not disclose confidential information regarding the Company, our service providers, the Trusts, the Funds, or our affiliates, unless disclosure is authorized or required by law. Confidential information includes all non-public information that might be harmful to, or useful to the competitors of, the Company, the Trusts, any Fund, our affiliates, our service providers, or our other business partners.

Fair Dealing

You must endeavor to deal fairly with companies or individuals with whom we do business or come into contact, including fellow employees of the Company and our competitors. You must not take unfair advantage of these or other parties by means of:

• manipulation;

• concealment;

• abuse of privileged information;

• misrepresentation of material facts; or

• any other unfair-dealing practice.

Protection and Proper Use of Company Assets

Our assets are to be used only for legitimate business purposes. You should protect our assets and ensure that they are used efficiently.

Incidental personal use of telephones, fax machines, copy machines, personal computers and similar equipment is generally allowed if there is no significant added cost to us, it does not interfere with your work duties, and is not related to an illegal activity or to any outside business.

Compliance with Applicable Laws, Rules and Regulations

Each of us has a duty to comply with all laws, rules and regulations that apply to our business. Highlighted below are some of the key compliance guidelines that must be followed.

• Insider trading. It is against the law to buy or sell securities using material information that is not available to the public. Individuals who give this “inside” information to others may be liable to the same extent as the individuals who trade while in possession of such information. You must not trade the units of any Fund, or the securities of our affiliates, our service providers, or any of our other business partners while in the possession of “inside” information.

3

• “Whistleblower” protections. It is against the law to discharge, demote, suspend, threaten, harass, or discriminate in any manner against an employee who provides information or otherwise assists in investigations or proceedings relating to violations of federal securities laws or other federal laws prohibiting fraud against unitholders. You must not discriminate in any way against an employee who engages in these “whistleblower” activities.

• Document Retention. You must adhere to appropriate procedures governing the retention and destruction of records consistent with applicable laws, regulations and our policies. You may not destroy, alter or falsify any document that may be relevant to a threatened or pending lawsuit or governmental investigation.

Please talk to any member of management if you have any questions about how to comply with the above regulations and other laws, rules and regulations.

Equal Opportunity, Harassment

We are committed to providing equal opportunity in all of our employment practices including selection, hiring, promotion, transfer, and compensation of all qualified applicants and employees without regard to race, color, sex or gender, religion, age, national origin, handicap, disability, citizenship status, or any other status protected by law. With this in mind, there are certain behaviors that will not be tolerated. These include harassment, violence, intimidation, and discrimination of any kind involving race, color, religion, gender, age, national origin, disability, or marital status.

Accuracy of Company Records

We require honest and accurate recording and reporting of information in order to make responsible business decisions. This includes such data as quality, safety, and personnel records, as well as financial records.

All financial books, records and accounts must accurately reflect transactions and events, and conform both to required accounting principles and to our system of internal controls. No false or artificial entries may be made.

Retaining Business Communications

The law requires us to maintain certain types of corporate records, usually for specified periods of time. Failure to retain those records for those minimum periods could subject us to penalties and fines, cause the loss of rights, obstruct justice, place us in contempt of court, or seriously disadvantage us in litigation.

4

From time to time we establish retention or destruction policies in order to ensure legal compliance. We expect you to fully comply with any published records retention or destruction policies, provided that you should note the following exception: If you believe, or we inform you, that our records are relevant to any litigation or governmental action, or any potential litigation or action, then you must preserve those records until we determine the records are no longer needed. This exception supersedes any previously or subsequently established destruction policies for those records. If you believe that this exception may apply, or have any questions regarding the possible applicability of that exception, please contact our Chief Compliance Officer, Howard Mah (the “Chief Compliance Officer”).

Political Contributions

No funds of the Company, of the Trusts or of any Fund may be given directly to political candidates. You may, however, engage in political activity with your own resources on your own time.

Media Relations

We must speak with a unified voice in all dealings with the press and other media. As a result, the President and CEO is the sole contact for media seeking information about the Company, the Trusts or any Fund. Any requests from the media must be referred to him. Unless another individual(s) is so authorized by the President and CEO. In the event the President and CEO and other authorized individual(s) are not available, clearance must be obtained through the Chief Compliance Officer.

Promotional Material

USCF, the Funds and the Trusts produce limited promotional material, which includes websites and a fact-sheet for each of the Funds. All promotional material developed by USCF, the Funds, including material posted on a website or printed on a fact-sheet, is reviewed for accuracy and approved prior to its public release by USCF’s counsel to ensure its compliance with the relevant requirements of the SEC, the Financial Industry Regulatory Authority (“FINRA”), the National Futures Association ( “NFA”) and the Commodity Futures Trading Commission (“CFTC”), and any other applicable regulatory authority.

In addition to procedures intended to safeguard against a Fund fact-sheet being misleading or deceptive, it is a USCF policy that Fund fact-sheets may only be distributed to the public when accompanied by the current applicable Fund prospectus.

As noted above, all content to be included on a Fund website is reviewed and approved by USCF’s counsel prior to publication of such content on such website. A review of website information is performed each time new information placed on the website would lead to a substantively new version of the web page. The review and approval of website material is documented by the supervisor in charge of such review.

USCF does not allow the use of personal websites by its employees or agents for the solicitation of business to any of the Funds.

5

USCF, or its service providers, maintains the supporting documentation for all statements, claims and performance results referenced in promotional material prepared by or on behalf of the Funds.

Intellectual Property Information

Information generated in our business is a valuable asset. Protecting this information plays an important role in our growth and ability to compete. Such information includes business and research plans; objectives and strategies; trade secrets; unpublished financial information; salary and benefits data; and business partner lists. Employees who have access to our intellectual property information are obligated to safeguard it from unauthorized access and must:

• Not disclose this information to persons outside of the Company;

• Not use this information for personal benefit or the benefit of persons outside of the Company; and

• Not share this information with other employees except on a legitimate “need to know” basis.

Internet and E-mail Policy

We may provide an e-mail system and Internet access to certain of our employees to help them do their work. You may use the e-mail system and the Internet only for legitimate business purposes in the course of your duties. Incidental and occasional personal use is permitted, but never for personal gain or any improper use. Further, you are prohibited from discussing or posting information regarding the Company, the Trusts or any of the Funds in any external electronic forum, including Internet chat rooms or electronic bulletin boards.

All employees engaged in the transmission of futures-related e-mails will be monitored periodically to ensure the accuracy of the information contained in such emails. Review of such emails is performed by ALPS, as principal to registered representatives on an annual basis. Review may also be undertaken by the Chief Compliance Officer and Counsel. This type of review is performed in conformity with NFA and FINRA guidance on e-mail review, in consideration of the fact that USCF generally communicates with institutional or relatively sophisticated clients, while USCF’s marketing agent handles most communication with the general public.

Reporting Violations and Internal Complaint Handling

You are responsible for compliance with the rules, standards and principles described in this Code. In addition, you should be alert to possible violations of the Code by the Company’s employees, officers and directors, and you are expected to report a violation promptly. Normally, reports should be made to one’s immediate supervisor. Under some circumstances, it may be impractical or you may feel uncomfortable raising a matter with your supervisor. In those instances, you are encouraged to contact our Chief Compliance Officer or General Counsel who will investigate and report the matter to the Board of Directors, as the circumstance dictates. You will also be expected to cooperate in an investigation of a violation.

6

Anyone who has a concern about our conduct, the conduct of an officer of the Company or our accounting, internal accounting controls or auditing matters, may communicate that concern to the Chief Compliance Officer or to the Audit Committee of the Board of Directors by direct communication with our Chairman of the Audit Committee or by e-mail or in writing. In addition, anyone who has a concern specifically about the Funds, may communicate that concern to the Chief Compliance Officer or to the Audit Committee. All reported concerns shall be forwarded to the Chief Compliance Officer or the Audit Committee, as applicable, in the same way that other concerns are addressed by us. The status of all outstanding concerns forwarded to the Audit Committee or the Chief Compliance Officer will be reported on a quarterly basis by our Chairman of the Audit Committee or Chief Compliance Officer, as applicable. The Audit Committee or Chief Compliance Officer, as applicable, may direct that certain matters be presented to the full Board of Directors and may also direct special treatment, including the retention of outside advisors or counsel, for any concern reported to it.

All reports will be investigated and whenever possible, requests for confidentiality shall be honored. And, while anonymous reports will be accepted, please understand that anonymity may hinder or impede the investigation of a report. All cases of questionable activity or improper actions will be reviewed for appropriate action, discipline or corrective actions. Whenever possible, we will keep confidential the identity of employees, officers or directors who are accused of violations, unless or until it has been determined that a violation has occurred.

There will be no reprisal, retaliation or adverse action taken against any employee who, in good faith, reports or assists in the investigation of, a violation or suspected violation, or who makes an inquiry about the appropriateness of an anticipated or actual course of action.

For reporting concerns about the conduct of the Company, the Trusts or any Fund, the conduct of an officer of the Company, or about accounting, internal accounting controls or auditing matters of the Company, the Trusts or any Fund, you may use the following means of communication:

Unitholder Complaint Handling

Complaints from unitholders of a Fund may raise compliance issues that need to be addressed in an expeditious manner. All complaints received by any associated person of USCF or any Fund are to be forwarded to the Chief Compliance Officer. Associated persons have been instructed to forward to the Chief Compliance Officer any oral questions that cannot be readily addressed so that such questions can be treated as complaints if the Chief Compliance Officer deems necessary. It is the general policy of USCF, the Trusts and the Funds to answer all complaints. A discussion of any complaints received will be an agenda item at each quarterly meeting of the Board of Directors of USCF.

The Chief Compliance Officer’s duties with respect to unitholder complaints include: (1) maintaining a log that documents all complaints, (2) investigating complaints as needed, (3) making a recommendation for resolution of all complaints received, and (4) instituting any necessary changes to policies and procedures in connection with or in response to complaints. USCF maintains records of all written complaints that are received by any party in connection with the Trusts and Funds, as well as records relating to the resolution of such complaints.

In light of the responsibilities placed on USCF’s marketing agent, it is likely that the marketing agent will also receive complaints from unitholders from time to time. The marketing agent will address these complaints pursuant to its own procedures, but notice of such complaints will be forwarded to the Chief Compliance Officer to be documented in the complaint log.

The marketing agent will be responsible for addressing any complaints that it receives pursuant to the marketing agent’s own procedures and will forward notice of material complaints to the Chief Compliance Officer. The Chief Compliance Officer must follow the complaint handling procedures described below:

Application/Waivers

All of the officers, directors, and employees are subject to this Code. Any waiver of this Code for an executive officer or director of the Company may only be made by the Board of Directors or the Audit Committee. Any waiver of the Code for an officer or member of our Boards of Directors must be promptly disclosed to unitholders.

NOTE 1 - ORGANIZATION AND BUSINESS

The United States Commodity Index Funds Trust (the “Trust”) was organized as a Delaware statutory trust on December 21, 2009. The Trust is a series trust formed pursuant to the Delaware Statutory Trust Act and includes the United States Commodity Index Fund (“USCI”), a commodity pool formed on April 1, 2010 and first made available to the public on August 10, 2010, the United States Copper Index Fund (“CPER”), a commodity pool formed on November 26, 2010 and first made available to the public on November 15, 2011, the United States Agriculture Index Fund (“USAG”), a commodity pool formed on November 26, 2010 and first made available to the public on April 13, 2012 and the United States Metals Index Fund (“USMI”), a commodity pool formed on November 26, 2010 and first made available to the public on June 19, 2012. USCI, CPER, USAG and USMI each issues units (“units”) that may be purchased and sold on the NYSE Arca, Inc. (the “NYSE Arca”). USCI, CPER, USAG and USMI are collectively referred to herein as the “Trust Series.” The Trust and each Trust Series operate pursuant to the Second Amended and Restated Declaration of Trust and Trust Agreement dated as of November 10, 2010 (the “Trust Agreement”). United States Commodity Funds LLC (“USCF”) is the sponsor of the Trust and the Trust Series and is also responsible for the management of the Trust and the Trust Series. For purposes of the financial statement presentation, unless specified otherwise, all references will be to the Trust Series.

USCF has the power and authority to establish and designate one or more series and to issue units thereof, from time to time as it deems necessary or desirable. USCF has exclusive power to fix and determine the relative rights and preferences as between the units of any series as to right of redemption, special and relative rights as to dividends and other distributions and on liquidation, conversion rights, and conditions under which the series shall have separate voting rights or no voting rights. The term for which the Trust is to exist commenced on the date of the filing of the Certificate of Trust, and the Trust and any Trust Series will exist in perpetuity, unless earlier terminated in accordance with the provisions of the Trust Agreement. Separate and distinct records must be maintained for each Trust Series and the assets associated with a Trust Series must be held in such separate and distinct records (directly or indirectly, including a nominee or otherwise) and accounted for in such separate and distinct records separately from the assets of any other Trust Series. Each Trust Series is separate from all other Trust Series created as series of the Trust in respect of the assets and liabilities allocated to that Trust Series and represents a separate investment portfolio of the Trust.

The sole Trustee of the Trust is Wilmington Trust Company (the “Trustee”), a Delaware banking corporation. The Trustee is unaffiliated with USCF. The Trustee’s duties and liabilities with respect to the offering of units and the management of the Trust are limited to its express obligations under the Trust Agreement.

USCF is a member of the National Futures Association (the “NFA”) and became a commodity pool operator (“CPO”) registered with the Commodity Futures Trading Commission (the “CFTC”) effective December 1, 2005. The Trust and each Trust Series have a fiscal year ending on December 31.

USCF is also the general partner of the United States Oil Fund, LP (“USOF”), the United States Natural Gas Fund, LP (“USNG”), the United States 12 Month Oil Fund, LP (“US12OF”), the United States Gasoline Fund, LP (“UGA”) and the United States Diesel-Heating Oil Fund, LP (formerly, the United States Heating Oil Fund, LP) (“USDHO”), which listed their limited partnership units on the American Stock Exchange (the “AMEX”) under the ticker symbols “USO” on April 10, 2006, “UNG” on April 18, 2007, “USL” on December 6, 2007, “UGA” on February 26, 2008 and “UHN” on April 9, 2008, respectively. As a result of the acquisition of the AMEX by NYSE Euronext, each of USOF’s, USNG’s, US12OF’s, UGA’s and USDHO’s units commenced trading on the NYSE Arca on November 25, 2008. USCF is also the general partner of the United States Short Oil Fund, LP (“USSO”), the United States 12 Month Natural Gas Fund, LP (“US12NG”) and the United States Brent Oil Fund, LP (“USBO”), which listed their limited partnership units on the NYSE Arca under the ticker symbols “DNO” on September 24, 2009, “UNL” on November 18, 2009 and “BNO” on June 2, 2010, respectively. All funds listed previously are referred to collectively herein as the “Related Public Funds.” USCF has also filed registration statements to register units of the United States Sugar Fund (“USSF”), the United States Natural Gas Double Inverse Fund (“UNGD”), the United States Gasoil Fund (“USGO”) and the United States Asian Commodities Basket Fund (“UAC”), each a series of the United States Commodity Funds Trust I, and the US Golden Currency Fund (“HARD”), a series of the United States Currency Funds Trust.

Effective as of May 1, 2012, each of USCI, CPER and USAG issue units to certain authorized purchasers (“Authorized Purchasers”) by offering baskets consisting of 50,000 units (“Creation Baskets”) through ALPS Distributors, Inc., as the marketing agent (the “Marketing Agent”). Prior to May 1, 2012, each of USCI, CPER and USAG issued units to Authorized Purchasers by offering baskets consisting of 100,000 units through the Marketing Agent. USMI was not available to the public until June 19, 2012, and from its inception of offering, issues units to certain Authorized Purchasers by offering baskets consisting of 50,000 units through the Marketing Agent. The purchase price for a Creation Basket is based upon the net asset value (“NAV”) of a unit calculated shortly after the close of the core trading session on the NYSE Arca on the day the order to create the basket is properly received.

From July 1, 2011 through May 1, 2013, Authorized Purchasers pay USCI $350 for each order placed to create one or more Creation Baskets or to redeem one or more baskets (“Redemption Baskets”), consisting of 50,000 units; prior to July 1, 2011, Authorized Purchasers paid USCI $1,000 for each order placed to create one or more Creation Baskets or to redeem one or more Redemption Baskets. From May 1, 2012 through May 31, 2013, Authorized Purchasers pay each of CPER, USAG and USMI $350 for each order placed to create one or more Creation Baskets or to redeem one or more Redemption Baskets; prior to May 1, 2012, Authorized Purchasers paid $1,000 for each order placed to create one or more Creation Baskets or to redeem one or more Redemption Baskets. Units may be purchased or sold on a nationally recognized securities exchange in smaller increments than a Creation Basket or Redemption Basket. Units purchased or sold on a nationally recognized securities exchange are not purchased or sold at the per unit NAV of each Trust Series but rather at market prices quoted on such exchange.

** All short contracts are offset by the same number of Futures Contracts in the corresponding long positions and are acquired solely for the purpose of reducing a long position (e.g., due to a redemption or to reflect a rebalancing of the Index).

Fair Value of Financial Instruments

12 Months Ended

Dec. 31, 2012

Fair Value of Financial Instruments

NOTE 9 – FAIR VALUE OF FINANCIAL INSTRUMENTS

The Trust and each Trust Series value their 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 the Trust and each Trust Series (observable inputs) and (2) the Trust’s and each Trust Series’ 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 USCI’s securities at December 31, 2012 using the fair value hierarchy:

NOTE 10 – RECENT ACCOUNTING PRONOUNCEMENTS

In December 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2011-11, “Balance Sheet (Topic 210): Disclosures about Offsetting Assets and Liabilities.” The amendments in ASU No. 2011-11 require an entity to disclose information about offsetting and related arrangements to enable users of its financial statements to understand the effect of those arrangements on its financial position. ASU No. 2011-11 is effective for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods. The guidance requires retrospective application for all comparative periods presented. USCF is currently evaluating the impact ASU No. 2011-11 will have on the Trust’s and each Trust Series’ financial statements.

Trust Series

NOTE 3 - TRUST SERIES

In connection with the execution of the First Trust Agreement on April 1, 2010, USCI was designated as the first series of the Trust. USCF contributed $1,000 to the Trust upon its formation on December 21, 2009, representing an initial contribution of capital to the Trust. Following the designation of USCI as the first series of the Trust, the initial capital contribution of $1,000 was transferred from the Trust to USCI and deemed an initial contribution to USCI. In connection with the commencement of USCI’s initial offering of units, USCF received 20 Sponsor Units of USCI in exchange for the previously received capital contribution, representing a beneficial ownership interest in USCI.

On July 30, 2010, USCI received a notice of effectiveness from the U.S. Securities and Exchange Commission (the “SEC”) for its registration of 50,000,000 units on Form S-1 with the SEC. On August 10, 2010, USCI listed its units on the NYSE Arca under the ticker symbol “USCI”. USCI established its initial per unit NAV by setting the price at $50.00 and issued 100,000 units in exchange for $5,000,000 on August 10, 2010. USCI also commenced investment operations on August 10, 2010 by purchasing Futures Contracts traded on the Futures Exchanges. In order to satisfy NYSE Arca listing standards that at least 100,000 units be outstanding at the beginning of the trading day on the NYSE Arca, USCF purchased the initial Creation Basket from the initial Authorized Purchaser at the initial offering price. The $1,000 fee that would otherwise be charged to the Authorized Purchaser in connection with an order to create or redeem was waived in connection with the initial Creation Basket. USCF held such initial Creation Basket until September 3, 2010, at which time the initial Authorized Purchaser repurchased the units comprising such basket in accordance with the specified conditions noted above. On September 14, 2011, USCF redeemed the 20 Sponsor Units of USCI and, on September 19, 2011, USCF purchased five units of USCI in the open market.

In connection with the Second Amended and Restated Trust Agreement dated November 10, 2010, USMI, USAG and CPER were designated as three additional series of the Trust. Following the designation of the additional series, an initial capital contribution of $3,000 was transferred from USCF to the Trust. On November 10, 2010, the Trust transferred $1,000 to each of USMI, USAG and CPER, which was deemed a capital contribution to each series. On November 14, 2011, USCF received 40 Sponsor Units of CPER in exchange for the previously received capital contribution, representing a beneficial interest in CPER. On December 7, 2011, USCF redeemed the 40 Sponsor Units of CPER and purchased 40 units of CPER in the open market. On April 13, 2012, USCF received 40 Sponsor Units of USAG in exchange for the previously received capital contribution, representing a beneficial interest in USAG. On June 28, 2012, USCF redeemed the 40 Sponsor Units of USAG and on October 3, 2012, purchased 5 units of USAG on the open market. On June 19, 2012, USCF received 40 Sponsor Units of USMI in exchange for the previously received capital contribution, representing a beneficial interest in USMI. On August 27, 2012, USCF redeemed the 40 Sponsor Units of USMI.

CPER, USAG and USMI received notice of effectiveness from the SEC for its registration of 30,000,000 CPER units, 20,000,000 USAG units and 20,000,000 USMI units on September 6, 2011. The order to permit listing CPER, USAG and USMI on the NYSE Arca was received on October 20, 2011. On November 15, 2011, CPER listed its units on the NYSE Arca under the ticker symbol “CPER.” CPER established its initial per unit NAV by setting the price at $25.00 and issued 100,000 units to the initial authorized purchaser, Merrill Lynch Professional Clearing Corp., in exchange for $2,500,000 in cash on November 15, 2011. The $1,000 fee that would otherwise be charged to the Authorized Purchaser in connection with an order to create or redeem was waived in connection with the initial Creation Basket.

On April 13, 2012, USAG listed its units on the NYSE Arca under the ticker symbol “USAG.” USAG established its initial per unit NAV by setting the price at $25.00. On April 14, 2012, USCF purchased 2 initial Creation Baskets of USAG. In accordance with applicable requirements of Regulation M under the Securities Exchange Act of 1934, no Creation Baskets were offered to Authorized Purchasers nor were the units listed on the NYSE Arca until five business days had elapsed from the date of USCF’s purchase of the initial Creation Basket on April 4, 2012. The $1,000 fee that would have otherwise been charged in connection with an order to create or redeem was waived in connection with the initial Creation Basket.

On June 19, 2012, USMI listed its units on the NYSE Arca under the ticker symbol “USMI.” USMI established its initial per unit NAV by setting the price at $25.00. On June 11, 2012, USCF purchased two initial Creation Baskets of USMI. In accordance with applicable requirements of Regulation M under the Securities Exchange Act of 1934, no Creation Baskets were offered to Authorized Purchasers nor were the units listed on the NYSE Arca until five business days had elapsed from the date of USCF’s purchase of the initial Creation Basket on June 11, 2012. The $350 fee that would have otherwise been charged in connection with an order to create or redeem was waived in connection with the initial Creation Basket. On August 29, 2012, USCF redeemed one of two initial Creation Baskets of USMI, leaving its holdings to 50,000 units.

USCI’s Investment Objective

USCI invests in futures contracts for commodities that are currently traded on the New York Mercantile Exchange (the “NYMEX”), ICE Futures (“ICE Futures”), Chicago Board of Trade (“CBOT”), Chicago Mercantile Exchange (“CME”), London Metal Exchange (“LME”), Commodity Exchange, Inc. (“COMEX”) or on other foreign exchanges (the NYMEX, ICE Futures, CBOT, CME, LME, Comex and other foreign exchanges, collectively, the “Futures Exchanges”) (such futures contracts, collectively, “Futures Contracts”) and, to a lesser extent, in order to comply with regulatory requirements or in view of market conditions, other commodity-based contracts and instruments such as cash-settled options on Futures Contracts, forward contracts relating to commodities, cleared swap contracts and other non exchange traded (“over-the-counter”) transactions that are based on the price of commodities and Futures Contracts (collectively, “Other Commodity-Related Investments”). Market conditions that USCF currently anticipates could cause USCI to invest in Other Commodity Related Investments would be those allowing USCI to obtain greater liquidity or to execute transactions with more favorable pricing. Futures Contracts and Other Commodity-Related Investments collectively are referred to as “Commodity Interests.”

The investment objective of USCI is for the daily changes in percentage terms of its units’ per unit net asset value (“NAV”) to reflect the daily changes in percentage terms of the SummerHaven Dynamic Commodity Index Total Return^SM (the “Commodity Index”), less USCI’s expenses. USCF does not intend to operate USCI in a fashion such that its per unit NAV will equal, in dollar terms, the spot prices of the commodities underlying the Benchmark Component Futures Contracts (as defined below) that comprise the Commodity Index or the prices of any particular group of Futures Contracts. USCI will not seek to achieve its stated investment objective over a period of time greater than one day. USCI believes that it is not practical to manage the portfolio to achieve such an investment goal when investing in Futures Contracts and Other Commodity-Related Investments. The Commodity Index is designed to reflect the performance of a diversified group of commodities. The Commodity Index is comprised of 14 Futures Contracts that are selected on a monthly basis from a list of 27 possible Futures Contracts. The Futures Contracts that at any given time make up the Commodity Index are referred to herein as “Benchmark Component Futures Contracts.” The Commodity Index is owned and maintained by SummerHaven Index Management, LLC (“SummerHaven Indexing”) and calculated and published by Bloomberg, L.P. USCI invests first in the current Benchmark Component Futures Contracts and other Futures Contracts intended to replicate the return on the current Benchmark Component Futures Contracts and, thereafter may hold Futures Contracts in a particular commodity other than one specified as the Benchmark Component Futures Contract, or may hold Other Commodity-Related Investments that are intended to replicate the return on the Benchmark Futures Contracts, but may fail to closely track the Commodity Index’s total return movements. If USCI increases in size, and due to its obligations to comply with regulatory limits or due to other market pricing or liquidity factors, USCI may invest in Futures Contract months other than the designated month specified as the Benchmark Component Futures Contract, or in Other Commodity-Related Investments, which may have the effect of increasing transaction related expenses and may result in increased tracking error.

USCI’s units began trading on August 10, 2010. As of December 31, 2012, USCI held 1,058 Futures Contracts on the NYMEX, 2,240 Futures Contracts on the ICE Futures, 3,405 Futures Contracts on the CBOT, 637 Futures Contracts on the CME, 5,701 Futures Contracts on the LME and did not hold any Futures Contracts on the COMEX.

CPER’s Investment Objective

The investment objective of CPER is for the daily changes in percentage terms of its units’ per unit NAV to reflect the daily changes in percentage terms of the SummerHaven Copper Index Total Return^SM (the “Copper Index”), less CPER’s expenses. USCF does not intend to operate CPER in a fashion such that its per unit NAV will equal, in dollar terms, the spot prices of the commodities underlying the Benchmark Component Copper Futures Contracts (as defined below) that comprise the Copper Index or the prices of any particular group of Futures Contracts. CPER will not seek to achieve a stated investment objective over a period of time greater than one day. USCF believes that it is not practical to manage the portfolio to achieve such an investment goal when investing in Futures Contracts and Other Copper-Related Investments (as defined below). The Copper Index is designed to reflect the performance of the investment returns from a portfolio of copper futures contracts. The Copper Index is owned and maintained by SummerHaven Indexing and calculated and published by the NYSE Arca. The Copper Index is comprised of either two or three Eligible Copper Futures Contracts that are selected on a monthly basis based on quantitative formulas relating to the prices of the Eligible Copper Futures Contracts developed by SummerHaven Indexing. The Eligible Copper Futures Contracts that at any given time make up the Copper Index are referred to herein as “Benchmark Component Copper Futures Contracts.”

CPER seeks to achieve its investment objective by investing to the fullest extent possible in the Benchmark Component Copper Futures Contracts. Then, if constrained by regulatory requirements or in view of market conditions, CPER will invest next in other Eligible Copper Futures Contracts, and finally to a lesser extent, in other exchange traded futures contracts that are economically identical or substantially similar to the Benchmark Component Copper Futures Contracts if one or more other Eligible Copper Futures Contracts is not available. When CPER has invested to the fullest extent possible in exchange-traded futures contracts, CPER may then invest in other contracts and instruments based on the Benchmark Component Copper Futures Contracts, other Eligible Copper Futures Contracts or copper, such as cash-settled options, forward contracts, cleared swap contracts and swap contracts other than cleared swap contracts. Other exchange-traded futures contracts that are economically identical or substantially similar to the Benchmark Component Copper Futures Contracts and other contracts and instruments based on the Benchmark Component Copper Futures Contracts, are collectively referred to collectively as “Other Copper-Related Investments,” and together with Benchmark Component Copper Futures Contracts and other Eligible Copper Futures Contracts, “Copper Interests.” CPER’s units began trading on November 15, 2011. As of December 31, 2012, CPER held 28 Futures Contracts on the COMEX.

USAG’s Investment Objective

The investment objective of USAG is for the daily changes in percentage terms of its units’ per unit NAV to reflect the daily changes in percentage terms of the SummerHaven Dynamic Agriculture Index Total Return^SM (the “Agriculture Index”), less USAG’s expenses. USCF does not intend to operate USAG in a fashion such that its per unit NAV will equal, in dollar terms, the spot prices of the commodities underlying the Benchmark Component Agriculture Futures Contracts (as defined below) that comprise the Agriculture Index or the prices of any particular group of Futures Contracts. USAG will not seek to achieve its stated investment objective over a period of time greater than one day. USCF believes that it is not practical to manage the portfolio to achieve such an investment goal when investing in Futures Contracts and Other Agriculture-Related Investments (as defined below). The Agriculture Index is designed to reflect the performance of a diversified group of agricultural commodities. The Agriculture Index is owned and maintained by SummerHaven Indexing and calculated and published by the NYSE Arca. Futures contracts for the agricultural commodities comprising the Agriculture Index are traded on ICE Future US, ICE Futures Canada, the CBOT, the Kansas City Board of Trade (“KCBT”) and the CME and are collectively referred to herein as “Eligible Agriculture Futures Contracts.” The Agriculture Index is comprised of 14 Eligible Agriculture Futures Contracts that are selected on a monthly basis based on quantitative formulas developed by SummerHaven Indexing. The Eligible Agriculture Futures Contracts that at any given time make up the Agriculture Index are referred to herein as “Benchmark Component Agriculture Futures Contracts.” The relative weighting of the Benchmark Component Agriculture Futures Contracts will change on a monthly basis, based on quantitative formulas relating to the prices of the Benchmark Component Agriculture Futures Contracts developed by SummerHaven Indexing.

USAG seeks to achieve its investment objective by investing to the fullest extent possible in the Benchmark Component Agriculture Futures Contracts. Then, if constrained by regulatory requirements or in view of market conditions, USAG will invest next in other Eligible Agriculture Futures Contracts based on the same agricultural commodity as the futures contracts subject to such regulatory constraints or market conditions, and finally, to a lesser extent, in other exchange traded futures contracts that are economically identical or substantially similar to the Benchmark Component Agriculture Futures Contracts if one or more other Eligible Agriculture Futures Contracts is not available. When USAG has invested to the fullest extent possible in exchange-traded futures contracts, USAG may then invest in other contracts and instruments based on the Benchmark Component Agriculture Futures Contracts, other Eligible Agriculture Futures Contracts or the agricultural commodities included in the Agriculture Index, such as cash-settled options, forward contracts, cleared swap contracts and swap contracts other than cleared swap contracts. Other exchange-traded futures contracts that are economically identical or substantially similar to the Benchmark Component Agriculture Futures Contracts and other contracts and instruments based on the Benchmark Component Agriculture Futures Contracts, as well as metals included in the Agriculture Index, are collectively referred to as “Other Agriculture-Related Investments,” and together with Benchmark Component Agriculture Futures Contracts and other Eligible Agriculture Futures Contracts, “Agriculture Interests.” USAG’s units began trading on April 13, 2012. As of December 31, 2012, USAG held 29 Futures Contracts on the ICE Futures, 9 Futures Contracts on the CME, 4 Futures Contracts on the KCBT and 30 Futures Contracts on the CBOT.

USMI’s Investment Objective

The investment objective of USMI is for the daily changes in percentage terms of its units’ per unit NAV to reflect the daily changes in percentage terms of the SummerHaven Metals Index Total Return^SM (the “Metals Index”), less USMI’s expenses. USCF does not intend to operate USMI in a fashion such that its per unit NAV will equal, in dollar terms, the spot prices of the commodities underlying the Benchmark Component Metals Futures Contracts (as defined below) that comprise the Metals Index or the prices of any particular group of Futures Contracts. USMI will not seek to achieve its stated investment objective over a period of time greater than one day. USCF believes that it is not practical to manage the portfolio to achieve such an investment goal when investing in Futures Contracts and Other Metals-Related Investments (as defined below). The Metals Index is owned and maintained by SummerHaven Indexing and calculated and published by the NYSE Arca. Futures contracts for the metals in the Metals Index that are traded on the NYMEX, the LME and COMEX are collectively referred to herein as “Eligible Metals Futures Contracts.” The Metals Index is comprised of 10 Eligible Metals Futures Contracts that are selected on a monthly basis based on quantitative formulas developed by SummerHaven Indexing. The Eligible Metals Futures Contracts that at any given time make up the Metals Index are referred to herein as “Benchmark Component Metals Futures Contracts.” The relative weighting of the Benchmark Component Metals Futures Contracts will change on a monthly basis, based on quantitative formulas relating to the prices of the Benchmark Component Metals Futures Contracts developed by SummerHaven Indexing.

USMI seeks to achieve its investment objective by investing to the fullest extent possible in the Benchmark Component Metals Futures Contracts. Then, if constrained by regulatory requirements or in view of market conditions, USMI will invest next in other Eligible Metals Futures Contracts, and finally to a lesser extent, in other exchange traded futures contracts that are economically identical or substantially similar to the Benchmark Component Metals Futures Contracts if one or more other Eligible Metals Futures Contracts is not available. When USMI has invested to the fullest extent possible in exchange-traded futures contracts, USMI may then invest in other contracts and instruments based on the Benchmark Component Metals Futures Contracts, other Eligible Metals Futures Contracts or the metals included in the Metals Index, such as cash-settled options, forward contracts, cleared swap contracts and swap contracts other than cleared swap contracts. Other exchange-traded futures contracts that are economically identical or substantially similar to the Benchmark Component Metals Futures Contracts and other contracts and instruments based on the Benchmark Component Metals Futures Contracts are collectively referred to as “Other Metals-Related Investments,” and together with Benchmark Component Metals Futures Contracts and other Eligible Metals Futures Contracts, “Metals Interests.” USMI’s units began trading on June 19, 2012. As of December 31, 2012, USMI held 2 Futures Contracts on the NYMEX, 1 Futures Contract on the CME, 70 Futures Contracts on the LME and 11 Futures Contracts on the COMEX.

CONTRACTS AND AGREEMENTS

NOTE 5 - CONTRACTS AND AGREEMENTS

USCF and the Trust, each on its own behalf and on behalf of each Trust Series, are party to a marketing agent agreement, dated as of July 22, 2010, as amended from time to time, with the Marketing Agent, whereby the Marketing Agent provides certain marketing services for each Trust Series as outlined in the agreement. The fee of the Marketing Agent, which is borne by USCF, is equal to 0.06% on each Trust Series’ assets up to $3 billion and 0.04% on each Trust Series’ assets in excess of $3 billion.

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

USCF and the Trust, on its own behalf and on behalf of each Trust Series, are also party to a custodian agreement, dated July 22, 2010, as amended from time to time, with Brown Brothers Harriman & Co. (“BBH&Co.”), whereby BBH&Co. holds investments on behalf of each Trust Series. USCF pays the fees of the custodian, which are determined by the parties from time to time. In addition, USCF and the Trust, on its own behalf and on behalf of each Trust Series, are party to an administrative agency agreement, dated July 22, 2010, as amended from time to time, with BBH&Co., whereby BBH&Co. acts as the administrative agent, transfer agent and registrar for each Trust Series. 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 each Trust Series 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 USCI’s, CPER’s, USAG’s, USMI’s, USOF’s, USNG’s, US12OF’s, UGA’s, USDHO’s, USSO’s, US12NG’s and USBO’s combined net assets, (b) 0.0465% for USCI’s, CPER’s, USAG’s, USMI’s, USOF’s, USNG’s, US12OF’s, UGA’s, USDHO’s, USSO’s, US12NG’s and USBO’s combined net assets greater than $500 million but less than $1 billion, and (c) 0.035% once USCI’s, CPER’s, USAG’s, USMI’s, USOF’s, USNG’s, US12OF’s, UGA’s, USDHO’s, USSO’s, US12NG’s and USBO’s combined net assets exceed $1 billion. The annual minimum amount will not apply if the asset-based charge for all accounts in the aggregate exceeds $75,000. USCF also pays transaction fees ranging from $7 to $15 per transaction.

Each Trust Series has entered into a brokerage agreement, dated March 1, 2010 for USCI and November 18, 2011 for each of CPER, USAG and USMI, as amended from time to time, with Newedge USA, LLC (“Newedge”). The agreement requires Newedge to provide services to each Trust Series in connection with the purchase and sale of Futures Contracts and Other Related Investments that may be purchased and sold by or through Newedge for each Trust Series’ account. In accordance with the agreement, Newedge charges each Trust Series commissions of approximately $7 to $15 per round-turn trade, including applicable exchange and NFA fees for Futures Contracts and options on Futures Contracts. Such fees include those incurred when purchasing Futures Contracts and options on Futures Contracts when each Trust Series issues units as a result of a Creation Basket, as well as fees incurred when selling Futures Contacts and options on Futures Contracts when each Trust Series redeems units as a result of a Redemption Basket. Such fees are also incurred when Futures Contracts and options on Futures Contracts are purchased or redeemed for the purpose of rebalancing the portfolio. Each Trust Series also incurs commissions to brokers for the purchase and sale of Futures Contracts, Other Commodity-Related Investments or Treasuries. During the year ended December 31, 2012, total commissions accrued to brokers amounted to $310,109 for USCI. Of this amount, approximately $296,759 was a result of rebalancing costs and approximately $13,350 was the result of trades necessitated by creation and redemption activity for USCI. By comparison, during the year ended December 31, 2011, total commissions accrued to brokers amounted to $307,284 for USCI. Of this amount, approximately $286,584 was a result of rebalancing costs and approximately $20,700 was the result of trades necessitated by creation and redemption activity for USCI. By comparison, during the year ended December 31, 2010, total commissions accrued to brokers amounted to $23,632. Of this amount, approximately $18,532 was a result of rebalancing costs and approximately $5,100 was the result of trades necessitated by creation and redemption activity for USCI. The increase in the total commissions accrued to brokers by USCI for the year ended December 31, 2012 as compared to the year ended December 31, 2011 was primarily due to an increase in USCI’s total net assets for the year ended December 31, 2012. The increase in the total commissions accrued to brokers by USCI for the year ended December 31, 2011 as compared to the year ended December 31, 2010, was primarily a function of an increase in USCI’s total net assets for the year ended December 31, 2011 and the fact that USCI was operating for only a portion of the year ended December 31, 2010 versus a full year of operations for the year ended December 31, 2011. As an annualized percentage of average total net assets, USCI’s figure for the year ended December 31, 2012 represents approximately 0.07% of USCI’s average total net assets. By comparison, USCI’s figure for the year ended December 31, 2011 represented approximately 0.08% of USCI’s average total net assets and the figure for the period ended December 31, 2010 represented approximately 0.15% of USCI’s 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.

During the year ended December 31, 2012, total commissions accrued to brokers amounted to $956 for CPER. Of this amount, approximately $799 was a result of rebalancing costs and approximately $157 was the result of trades necessitated by creation and redemption activity. By comparison, during the year ended December 31, 2011, total commissions paid to brokers amounted to $177 for CPER. Of this amount, approximately $45 was a result of rebalancing costs and approximately $132 was the result of trades necessitated by creation and redemption activity for CPER. The increase in CPER’s total commissions accrued to brokers for the year ended December 31, 2012 as compared to the year ended December 31, 2011, was primarily due an increase in CPER’s total net assets for the year ended December 31, 2012 and that CPER was operating for only a portion of the year ended December 31, 2011 versus a full year of operations for the year ended December 31, 2012. As an annualized percentage of average total net assets, CPER’s figure for the year ended December 31, 2012 represents approximately 0.04% of CPER’s average total net assets. By comparison, CPER’s figure for the year ended December 31, 2011 represented approximately 0.06% of CPER’s 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.

During the year ended December 31, 2012, total commissions accrued to brokers amounted to $2,632 for USAG. Of this amount, approximately $2,090 was a result of rebalancing costs and approximately $542 was the result of trades necessitated by creation and redemption activity. As an annualized percentage of average daily total net assets, USAG’s figure for the year ended December 31, 2012 represents approximately 0.12% of USAG’s average daily total net assets. However, there can be no assurance that commission costs and portfolio turnover will not cause commission expenses to rise in future quarters.

During the year ended December 31, 2012, total commissions accrued to brokers amounted to $714 for USMI. Of this amount, approximately $512 was a result of rebalancing costs and approximately $202 was the result of trades necessitated by creation and redemption activity. As an annualized percentage of average daily total net assets, USMI’s figure for the year ended December 31, 2012 represents approximately 0.05% of USMI’s average daily total net assets. However, there can be no assurance that commission costs and portfolio turnover will not cause commission expenses to rise in future quarters.

USCF is party to an Amended Advisory Agreement, dated July 1, 2011, as amended from time to time, with SummerHaven, whereby SummerHaven provides advisory services to USCF with respect to the Applicable Index for each Trust Series and investment decisions for each Trust Series. SummerHaven’s advisory services include, but are not limited to, general consultation regarding the calculation and maintenance of the Applicable Index for each Trust Series, anticipated changes to each Applicable Index and the nature of each Applicable Index’s current or anticipated component securities. For these services, USCF pays SummerHaven a fee based on a percentage of the average total net assets of each Trust Series. For USCI, the fee is equal to the percentage fees paid to USCF minus 0.14%, with that result multiplied by 0.5, minus 0.06% to arrive at the actual fee paid. For each of CPER, USAG and USMI, the fee is equal to the percentage fees paid to USCF minus 0.18%, with that result multiplied by 0.5, minus 0.6% to arrive at the actual fee paid.

USCF is also party to an Amended Licensing Agreement, dated July 1, 2011, as amended from time to time, with SummerHaven, whereby SummerHaven sub-licensed to each Trust Series the use of certain names and marks, including the Applicable Index for each Trust Series for which SummerHaven has a sub-license from SummerHaven Indexing, the owner of each Applicable Index. Under the Licensing Agreement, USCF paid SummerHaven an annual fee of $15,000 per each Trust Series for the year ended December 31, 2012, plus an annual fee of 0.06% of the average daily total net assets of each Trust Series.

Financial Instruments, Off-balance Sheet Risks and Contingencies

Financial Instruments, Off-balance Sheet Risks and Contingencies

NOTE 6 - FINANCIAL INSTRUMENTS, OFF-BALANCE SHEET RISKS AND CONTINGENCIES

Each Trust Series engages in the trading of futures contracts and options on futures contracts and may engage in cleared swaps (collectively, “derivatives”). As such, each Trust Series 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.

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

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

Futures contracts 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 each Trust Series 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.

All of the Futures Contracts held by each Trust Series were exchange-traded through December 31, 2012. The risks associated with exchange-traded contracts are generally perceived to be less than those associated with over-the-counter transactions since, in over-the-counter transactions, a party must rely solely on the credit of its respective individual counterparties. However, in the future, if each Trust Series were to enter into non-exchange traded contracts, it would be subject to the credit risk associated with counterparty non-performance. The credit risk from counterparty non-performance associated with such instruments is the net unrealized gain, if any, on the transaction. Currently, each Trust Series 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, each Trust Series bears the risk of financial failure by the clearing broker.

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

USCF may invest a portion of each Trust Series’ cash in money market funds that seek to maintain a stable per unit NAV. Each Trust Series may be exposed to any risk of loss associated with an investment in such money market funds. As of December 31, 2012 and December 31, 2011, none of the Trust Series held investments in money market funds. Each Trust Series 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, 2012 and December 31, 2011, USCI held cash deposits and investments in Treasuries in the amounts of $491,119,704 and $374,465,568, respectively, with the custodian and futures commission merchant. As of December 31, 2012 and December 31, 2011, CPER held cash deposits and investments in Treasuries in the amounts of $2,541,590 and $2,511,610, respectively, with the custodian and futures commission merchant. As of December 31, 2012 and December 31, 2011, USAG held cash deposits and investments in Treasuries in the amounts of $2,679,845 and $1,000, respectively, with the custodian and futures commission merchant. As of December 31, 2012 and December 31, 2011, USMI held cash deposits and investments in Treasuries in the amounts of $2,605,049 and $1,000, respectively, with the custodian and futures commission merchant. Some or all of these amounts may be subject to loss should the Trust Series’ custodian and/or futures commission merchant cease operations.

For derivatives, risks arise from changes in the market value of the contracts. Theoretically, each Trust Series 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, each Trust Series 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.

The Trust Series’ 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, the Trust Series or USCF have a policy of requiring review of the credit standing of each broker or counterparty with which they conduct business.

The financial instruments held by the applicable Trust Series 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.

Summary Of Significant Accounting Policies

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. Each Trust Series earns interest on its assets denominated in U.S. dollars on deposit with the futures commission merchant at the 90-day Treasury bill rate. In addition, each Trust Series earns income on funds held at the custodian and/or futures commission merchant at prevailing market rates earned on such investments.

Brokerage Commissions

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

Income Taxes

The Trust Series are not subject to federal income taxes; each investor 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”), each Trust Series 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. Each Trust Series files an income tax return in the U.S. federal jurisdiction, and may file income tax returns in various U.S. states. None of the Trust Series is subject to income tax return examinations by major taxing authorities for years before 2010 (year of the Trust Series’ inception, but not necessarily the commencement of operations for each Trust Series). 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 each Trust Series recording a tax liability that reduces net assets. However, each Trust Series’ 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. Each Trust Series 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, 2012 for any Trust Series.

Trust Capital and Allocation of Income and Losses

Profit or loss shall be allocated among the unitholders of each Trust Series in proportion to the number of units each investor holds as of the close of each month. USCF may revise, alter or otherwise modify this method of allocation as described in the Trust Agreement.

Adoption of New Monthly Allocation Convention

Effective January 1, 2012, USCI adopted a new convention for allocating items of income, gain, loss, deduction and credits. In situations where a partner’s interest in a partnership is sold or otherwise transferred during a taxable year, the Code generally requires that partnership tax items for the year be allocated among the partners using either an interim closing of the books or a daily proration method. USCI uses an interim closing of the books method under which income, gains and losses (both realized and unrealized), deductions and credits are determined on a monthly basis. Prior to January 1, 2012, USCI allocated these tax items among the holders of the units (including those who dispose of units during a taxable year) in proportion to the number of units owned by them on the last trading day of each month. For this purpose, if an investor holds a unit as of the close of business of the last trading day of a particular month, such investor is treated as if it owned the unit throughout the month and thus is allocated all of the items of income, gain, deduction, loss or credit attributable to that unit for such month (the “same-month convention”).

Effective January 1, 2012 for USCI, November 15, 2011 for CPER, April 13, 2012 for USAG and June 19, 2012 for USMI, an allocation convention is applied pursuant to which each Trust Series’ tax items for each month will be allocated among the holders of units in proportion to the number of units owned by them as of the close of business of the last trading day of the previous month. If an investor who holds a unit as of the close of business on the last trading day of the previous month disposes of a unit during the current month, such investor will be treated for purposes of making allocations as if it owned the unit throughout the current month (the “next-month convention”). For example, an investor who buys a unit on April 10 of a year and sells it on May 20 of the same year will be allocated all of the tax items attributable to May (because he or she is deemed to hold it through the last day of May) but will not be allocated any of the tax items attributable to April. The tax items attributable to that unit for April will be allocated to the person who is the actual or deemed holder of the unit as of the close of business on the last trading day of March.

For investors in USCI, as a result of the transition from the same-month convention to the next-month convention, an investor who bought a unit in December 2011 and sold the unit on or after January 1, 2012 will be allocated the tax items attributable to that unit for December 2011 as well as the tax items attributable to that unit for 2012.

Creations and Redemptions

Authorized Purchasers may purchase Creation Baskets or redeem Redemption Baskets only in blocks of 50,000 units. Effective as of May 1, 2012, Authorized Purchasers may purchase Creation Baskets or redeem Redemption Baskets for USCI, CPER and USAG only in blocks of 50,000 units at a price equal to the NAV of the units calculated shortly after the close of the core trading session on the NYSE Arca on the day the order is placed. Prior to May 1, 2012, Authorized Purchasers could only purchase Creation Baskets or redeem Redemption Baskets for USCI, CPER and USAG in blocks of 100,000 units. USMI was not available to the public until June 19, 2012, and from its inception of offering, Authorized Purchasers could only purchase Creation Baskets in blocks of 50,000 units.

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

Calculation of Net Asset Value Per Unit

Each Trust Series’ per unit NAV is calculated on each NYSE Arca trading day by taking the current market value of its total assets, subtracting any liabilities and dividing the amount by the total number of units issued and outstanding. Each Trust Series uses the closing prices on the relevant Futures Exchanges (as defined in Note 3 below) of the Applicable Benchmark Component Futures Contracts (as defined in Note 3 below) that at any given time make up the Applicable Index (as defined in Note 3 below) (determined at the earlier of the close of such exchange or 2:30 p.m. New York time) for the contracts traded on the Futures Exchanges, but calculates or determines the value of all other investments of each Trust Series using market quotations, if available, or other information customarily used to determine the fair value of such investments.

Net Income (Loss) Per Unit

Net income (loss) per unit is the difference between the per unit NAV at the beginning of each period and the per unit NAV at the end of each period. The weighted average number of units outstanding was computed for purposes of disclosing net income (loss) per weighted average unit. The weighted average units are equal to the number of units outstanding at the end of the period, adjusted proportionately for units added and redeemed based on the amount of time the units were outstanding during such period. As of December 31, 2012, USCF held 50,000 units of USMI.

Offering Costs

Offering costs incurred in connection with the registration of units prior to the commencement of the offering are borne by USCF. Offering costs incurred in connection with the registration of additional units after the commencement of the offering are borne by each Trust Series. These costs include registration fees paid to regulatory agencies and all legal, accounting, printing and other expenses associated with such offerings. Costs borne by the Trust Series after the commencement of an offering 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.

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.

Reclassification

The audited financial statements for the year ended December 31, 2010 have been adjusted to reflect a non-material capital contribution of cash from USCF in the amount of $3,000. The $3,000 capital contribution was received by the Trust from USCF on November 10, 2010.

Adoption of New Accounting Pronouncement Effect

Adoption of New Monthly Allocation Convention

Adoption of New Monthly Allocation Convention

Effective January 1, 2012, USCI adopted a new convention for allocating items of income, gain, loss, deduction and credits. In situations where a partner’s interest in a partnership is sold or otherwise transferred during a taxable year, the Code generally requires that partnership tax items for the year be allocated among the partners using either an interim closing of the books or a daily proration method. USCI uses an interim closing of the books method under which income, gains and losses (both realized and unrealized), deductions and credits are determined on a monthly basis. Prior to January 1, 2012, USCI allocated these tax items among the holders of the units (including those who dispose of units during a taxable year) in proportion to the number of units owned by them on the last trading day of each month. For this purpose, if an investor holds a unit as of the close of business of the last trading day of a particular month, such investor is treated as if it owned the unit throughout the month and thus is allocated all of the items of income, gain, deduction, loss or credit attributable to that unit for such month (the “same-month convention”).

Effective January 1, 2012 for USCI, November 15, 2011 for CPER, April 13, 2012 for USAG and June 19, 2012 for USMI, an allocation convention is applied pursuant to which each Trust Series’ tax items for each month will be allocated among the holders of units in proportion to the number of units owned by them as of the close of business of the last trading day of the previous month. If an investor who holds a unit as of the close of business on the last trading day of the previous month disposes of a unit during the current month, such investor will be treated for purposes of making allocations as if it owned the unit throughout the current month (the “next-month convention”). For example, an investor who buys a unit on April 10 of a year and sells it on May 20 of the same year will be allocated all of the tax items attributable to May (because he or she is deemed to hold it through the last day of May) but will not be allocated any of the tax items attributable to April. The tax items attributable to that unit for April will be allocated to the person who is the actual or deemed holder of the unit as of the close of business on the last trading day of March.

For investors in USCI, as a result of the transition from the same-month convention to the next-month convention, an investor who bought a unit in December 2011 and sold the unit on or after January 1, 2012 will be allocated the tax items attributable to that unit for December 2011 as well as the tax items attributable to that unit for 2012.
