Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
Organization And Business | 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. On January 30, 2015, USCF as the sponsor of the “Trust and its series USMI announced that its officers and members had authorized a plan to (i) liquidate USMI, (ii) terminate the continuous offering of USMI, and (iii) deregister USMI under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and therefore, terminate the Trust’s obligation to include USMI on its periodic and current reports with the Securities and Exchange Commission (“SEC”). USCF has submitted written notice to the NYSE Arca, Inc. (“NYSE Arca”) of its decision to liquidate USMI, terminate the offering and to terminate USMI’s obligations under the Exchange Act. | |
Shares of USMI will cease trading on the NYSE Arca and will be closed to purchase by investors as of the close of regular trading on the NYSE Arca on March 18, 2015 (the “Closing Date”). On March 18, 2015, USMI will cease accepting orders for Creation Baskets and Redemption Baskets. The Trust will file a post-effective amendment to the registration statement on behalf of USMI to terminate the offering of registered and unsold shares of USMI. The post-effective amendment to the registration statement will be effective on March 18, 2015. | |
Shareholders may sell shares of USMI prior to the Closing Date and customary brokerage charges, or Redemption Basket charges, as the case may be, may apply to these transactions. From March 18, 2015 through about March 25, 2015 (the “Liquidation Date”) there is no assurance that there will be a market for shares of USMI. Between the Closing Date and the Liquidation Date, USMI will be in the process of closing down and liquidating its portfolio. This process will result in USMI increasing its cash holdings and, as a consequence, not tracking its index, the SummerHaven Metals Index Total ReturnSM, which may not be consistent with USMI’s investment objective and strategy. | |
On or about the Liquidation Date, USMI will liquidate its assets and distribute cash pro rata to all remaining shareholders who have not previously redeemed or exchanged their shares. These distributions are taxable events. Once the distributions are complete, USMI will terminate. | |
USCF has determined that USMI could not continue its business and operations in an economically efficient manner due to USMI’s inability to attract sufficient assets, thereby hindering its ability to operate efficiently. | |
USCF intends to file a post-effective amendment on behalf of the Trust and USMI to terminate the offering of the registered and unsold shares of USMI. The NYSE Arca will file a Form 25 with the SEC to affect the withdrawal of the listing of USMI from the NYSE Arca. Delisting from the NYSE Arca will become effective 10 days after the filing date of the Form 25. Provided that USMI continues to meet the applicable legal requirements, USCF intends to file a Form 15 on behalf of the Trust and USMI with the SEC in early April 2015 to suspend the Trust’s duty to include USMI on its reports under Sections 13(a) and 15(d) of the Exchange Act. USMI expects the termination of registration will become effective 90 days after the date of the filing of the Form 15 with the SEC. | |
USCI, CPER and USAG each issues shares (“shares”) that may be purchased and sold on 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 shares 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 shares 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 shares 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 (“USO”), the United States Natural Gas Fund, LP (“UNG”), the United States 12 Month Oil Fund, LP (“USL”), the United States Gasoline Fund, LP (“UGA”) and the United States Diesel-Heating Oil Fund, LP (“UHN”), which listed their limited partnership shares on the American Stock Exchange (the “AMEX”) under the ticker symbols “USO” on April 10, 2006, “UNG” on April 18, 2007, “USL” on December 6, 2007, “UGA” on February 26, 2008 and “UHN” on April 9, 2008, respectively. As a result of the acquisition of the AMEX by NYSE Euronext, each of USO’s, UNG’s, USL’s, UGA’s and UHN’s shares commenced trading on the NYSE Arca on November 25, 2008. USCF is also the general partner of the United States Short Oil Fund, LP (“DNO”), the United States 12 Month Natural Gas Fund, LP (“UNL”) and the United States Brent Oil Fund, LP (“BNO”), which listed their limited partnership shares on the NYSE Arca under the ticker symbols “DNO” on September 24, 2009, “UNL” on November 18, 2009 and “BNO” on June 2, 2010, respectively. All funds listed previously are referred to collectively herein as the “Related Public Funds.” On January 30, 2015, USCF as the sponsor of the Trust and its series USMI announced that its officers and members had authorized a plan to (i) liquidate USMI, (ii) terminate the continuous offering of USMI, and (iii) deregister USMI under the Exchange Act, and therefore, terminate the Trust’s obligation to include USMI on its periodic and current reports with the SEC. USCF has submitted written notice to the NYSE Arca of its decision to liquidate USMI, terminate the offering and to terminate USMI’s obligations under the Exchange Act. | |
USCF intends to file a post-effective amendment on behalf of the Trust and USMI to terminate the offering of the registered and unsold shares of USMI. The NYSE Arca will file a Form 25 with the SEC to affect the withdrawal of the listing of USMI from the NYSE Arca. Delisting from Arca will become effective 10 days after the filing date of the Form 25. Provided that USMI continues to meet the applicable legal requirements, USCF intends to file a Form 15 on behalf of the Trust and USMI with the SEC in early April 2015 to suspend the Trust’s duty to include USMI on its reports under Sections 13(a) and 15(d) of the Exchange Act. USMI expects the termination of registration will become effective 90 days after the date of the filing of the Form 15 with the SEC. | |
Effective as of May 1, 2012, each of USCI, CPER and USAG issue shares to certain authorized purchasers (“Authorized Participants”) by offering baskets consisting of 50,000 shares (“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 shares to Authorized Participants by offering baskets consisting of 100,000 shares through the Marketing Agent. USMI was not available to the public until June 19, 2012, and from its inception of offering, issues shares to certain Authorized Participants by offering baskets consisting of 50,000 shares through the Marketing Agent. The purchase price for a Creation Basket is based upon the net asset value (“NAV”) of a share calculated shortly after the close of the core trading session on the NYSE Arca on the day the order to create the basket is properly received. | |
From July 1, 2011 through December 31, 2014 (and continuing at least through May 1, 2015), Authorized Participants 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 shares; prior to July 1, 2011, Authorized Participants 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 December 31, 2014 (and continuing at least through May 1, 2015), Authorized Participants pay each of CPER and USAG $350 for each order placed to create one or more Creation Baskets or to redeem one or more Redemption Baskets (for USMI, from May 1, 2012 through March 18, 2015); prior to May 1, 2012, Authorized Participants paid $1,000 for each order placed to create one or more Creation Baskets or to redeem one or more Redemption Baskets. Shares may be purchased or sold on a nationally recognized securities exchange in smaller increments than a Creation Basket or Redemption Basket. Shares purchased or sold on a nationally recognized securities exchange are not purchased or sold at the per share NAV of each Trust Series but rather at market prices quoted on such exchange. | |

The financial statements have been prepared in conformity with GAAP as detailed in the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification. Each Trust Series is an investment company and follows the accounting and reporting guidance in FASB Topic 946. | |
Revenue Recognition | |
Commodity futures contracts, forward contracts, physical commodities, and related options are recorded on the trade date. All such transactions are recorded on the identified cost basis and marked to market daily. Unrealized gains or losses on open contracts are reflected in the 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 (“FCM”) at the 90-day Treasury bill rate. In addition, each Trust Series earns income on funds held at the custodian and/or FCM at prevailing market rates earned on such investments. | |
Brokerage Commissions | |
Brokerage commissions on all open commodity futures contracts are accrued on a full-turn basis. | |
Income Taxes | |
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 2011. The tax benefit recognized is measured as the largest amount of benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement. De-recognition of a tax benefit previously recognized results in 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, 2014 for any Trust Series. | |
Trust Capital and Allocation of Income and Losses | |
Profit or loss shall be allocated among the shareholders of each Trust Series in proportion to the number of shares 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. | |
Creations and Redemptions | |
Authorized Participants may purchase Creation Baskets or redeem Redemption Baskets only in blocks of 50,000 shares. Effective as of May 1, 2012, Authorized Participants may purchase Creation Baskets or redeem Redemption Baskets for USCI, CPER and USAG only in blocks of 50,000 shares at a price equal to the NAV of the shares calculated shortly after the close of the core trading session on the NYSE Arca on the day the order is placed. Prior to May 1, 2012, Authorized Participants could only purchase Creation Baskets or redeem Redemption Baskets for USCI, CPER and USAG in blocks of 100,000 shares. USMI was not available to the public until June 19, 2012, and from its inception of offering, Authorized Participants could only purchase Creation Baskets in blocks of 50,000 shares. | |
Each Trust Series receives or pays the proceeds from shares sold or redeemed within three business days after the trade date of the purchase or redemption. The amounts due from Authorized Participants are reflected in each Trust Series’ statements of financial condition as receivable for shares sold, and amounts payable to Authorized Participants upon redemption are reflected as payable for shares redeemed. | |
Calculation of Net Asset Value Per Share | |
Each Trust Series’ per share NAV is calculated on each NYSE Arca trading day by taking the current market value of its total assets, subtracting any liabilities and dividing the amount by the total number of shares 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 Share | |
Net income (loss) per share is the difference between the per share NAV at the beginning of each period and the per share NAV at the end of each period. The weighted average number of shares outstanding was computed for purposes of disclosing net income (loss) per weighted average share. The weighted average shares are equal to the number of shares outstanding at the end of the period, adjusted proportionately for shares added and redeemed based on the amount of time the shares were outstanding during such period. As of December 31, 2014, USCF held 5 shares of USCI, 40 shares of CPER, 5 shares of USAG and 5 shares of USMI. | |
Offering Costs | |
Offering costs incurred in connection with the registration of shares prior to the commencement of the offering are borne by USCF. Offering costs incurred in connection with the registration of additional shares 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. | |
Reclassifications | |
Certain prior year amounts have been reclassified to conform to the current year presentation. | |
Use of Estimates | |
The preparation of financial statements in conformity with GAAP requires USCF to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of the revenue and expenses during the reporting period. Actual results may differ from those estimates and assumptions. | |

Trust Series [Abstract] | |
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 shares, USCF received 20 Sponsor Shares 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 shares on Form S-1 with the SEC. On August 10, 2010, USCI listed its shares on the NYSE Arca under the ticker symbol “USCI”. USCI established its initial per share NAV by setting the price at $50.00 and issued 100,000 shares 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 shares be outstanding at the beginning of the trading day on the NYSE Arca, USCF purchased the initial Creation Basket from the initial Authorized Participant at the initial offering price. The $1,000 fee that would otherwise be charged to the Authorized Participant 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 Participant repurchased the shares comprising such basket in accordance with the specified conditions noted above. On September 14, 2011, USCF redeemed the 20 Sponsor Shares of USCI and, on September 19, 2011, USCF purchased five shares 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 Shares 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 Shares of CPER and purchased 40 shares of CPER in the open market. On April 13, 2012, USCF received 40 Sponsor Shares of USAG in exchange for the previously received capital contribution, representing a beneficial interest in USAG.

On June 19, 2012, USCF received 40 Sponsor Shares 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 Shares of USMI and on September 4, 2013, purchased 5 shares of USMI on the open market. | |
CPER, USAG and USMI received notice of effectiveness from the SEC for its registration of 30,000,000 CPER shares, 20,000,000 USAG shares and 20,000,000 USMI shares 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 shares on the NYSE Arca under the ticker symbol “CPER.” CPER established its initial per share NAV by setting the price at $25.00 and issued 100,000 shares to the initial Authorized Participant, 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 Participant 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 shares on the NYSE Arca under the ticker symbol “USAG.” USAG established its initial per share 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 Participants nor were the shares 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 shares on the NYSE Arca under the ticker symbol “USMI.” USMI established its initial per share NAV by setting the price at $25.00.

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 shares. | |
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 nonexchange 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 shares’ per share Net Asset Value (“NAV”) to reflect the daily changes in percentage terms of the SummerHaven Dynamic Commodity Index Total ReturnSM (the “SDCI”), less USCI’s expenses. USCF does not intend to operate USCI in a fashion such that its per share NAV will equal, in dollar terms, the spot prices of the commodities underlying the Benchmark Component Futures Contracts (as defined below) that comprise the SDCI 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 SDCI is designed to reflect the performance of a diversified group of commodities. The SDCI is comprised of 14 Futures Contracts that are selected on a monthly basis from a list of 27 possible Futures Contracts. The Futures Contracts that at any given time make up the SDCI are referred to herein as “Benchmark Component Futures Contracts.” The SDCI is owned and maintained by SummerHaven Index Management, LLC (“SHIM”) 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 SDCI’s total return movements. If USCI increases in size, and due to its obligations to comply with regulatory limits or due to other market pricing or liquidity factors, USCI may invest in Futures Contract months other than the designated month specified as the Benchmark Component Futures Contract, or in Other Commodity-Related Investments, which may have the effect of increasing transaction related expenses and may result in increased tracking error. | |
USCI’s shares began trading on August 10, 2010. As of December 31, 2014, USCI held 657 Futures Contracts on the NYMEX, 2,553 Futures Contracts on the ICE Futures, 5,487 Futures Contracts on the CBOT, 2,861 Futures Contracts on the CME, 5,001 Futures Contracts on the LME and 430 Futures Contracts on the COMEX, totaling 16,989 futures contracts. | |
CPER’s Investment Objective | |
The investment objective of CPER is for the daily changes in percentage terms of its shares’ per share NAV to reflect the daily changes in percentage terms of the SummerHaven Copper Index Total ReturnSM (the “SCI”), less CPER’s expenses. USCF does not intend to operate CPER in a fashion such that its per share 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 SCI 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 SCI is designed to reflect the performance of the investment returns from a portfolio of copper futures contracts. The SCI is owned and maintained by SHIM and calculated and published by the NYSE Arca. The SCI is comprised of either two or three Eligible Copper Futures Contracts that are selected on a monthly basis based on quantitative formulas relating to the prices of the Eligible Copper Futures Contracts developed by SHIM. The Eligible Copper Futures Contracts that at any given time make up the SCI are referred to herein as “Benchmark Component Copper Futures Contracts.” | |
CPER seeks to achieve its investment objective by investing to the fullest extent possible in the Benchmark Component Copper Futures Contracts. Then, if constrained by regulatory requirements or in view of market conditions, CPER will invest next in other Eligible Copper Futures Contracts, and finally to a lesser extent, in other exchange traded futures contracts that are economically identical or substantially similar to the Benchmark Component Copper Futures Contracts if one or more other Eligible Copper Futures Contracts is not available. When CPER has invested to the fullest extent possible in exchange-traded futures contracts, CPER may then invest in other contracts and instruments based on the Benchmark Component Copper Futures Contracts, other Eligible Copper Futures Contracts or copper, such as cash-settled options, forward contracts, cleared swap contracts and swap contracts other than cleared swap contracts. 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 shares began trading on November 15, 2011. As of December 31, 2014, CPER held 40 Futures Contracts on the COMEX. | |
USAG’s Investment Objective | |
The investment objective of USAG is for the daily changes in percentage terms of its shares’ per share NAV to reflect the daily changes in percentage terms of the SummerHaven Dynamic Agriculture Index Total ReturnSM (the “SDAI”), less USAG’s expenses. USCF does not intend to operate USAG in a fashion such that its per share 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 SDAI 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 SDAI is designed to reflect the performance of a diversified group of agricultural commodities. The SDAI is owned and maintained by SHIM and calculated and published by the NYSE Arca. Futures contracts for the agricultural commodities comprising the SDAI are traded on ICE Future US, ICE Futures Canada, the CBOT, the Kansas City Board of Trade (“KCBT”) and the CME and are collectively referred to herein as “Eligible Agriculture Futures Contracts.” The SDAI is comprised of 14 Eligible Agriculture Futures Contracts that are selected on a monthly basis based on quantitative formulas developed by SHIM. The Eligible Agriculture Futures Contracts that at any given time make up the SDAI 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 SHIM. | |
USAG seeks to achieve its investment objective by investing to the fullest extent possible in the Benchmark Component Agriculture Futures Contracts. Then, if constrained by regulatory requirements or in view of market conditions, USAG will invest next in other Eligible Agriculture Futures Contracts based on the same agricultural commodity as the futures contracts subject to such regulatory constraints or market conditions, and finally, to a lesser extent, in other exchange traded futures contracts that are economically identical or substantially similar to the Benchmark Component Agriculture Futures Contracts if one or more other Eligible Agriculture Futures Contracts is not available. When USAG has invested to the fullest extent possible in exchange-traded futures contracts, USAG may then invest in other contracts and instruments based on the Benchmark Component Agriculture Futures Contracts, other Eligible Agriculture Futures Contracts or the agricultural commodities included in the SDAI, such as cash-settled options, forward contracts, cleared swap contracts and swap contracts other than cleared swap contracts. 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 SDAI, 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 shares began trading on April 13, 2012. As of December 31, 2014, USAG held 41 Futures Contracts on the ICE Futures, 8 Futures Contracts on the CME, 2 Futures Contract on the KCBT and 31 Futures Contracts on the CBOT, totaling 82 futures contracts. | |
USMI’s Investment Objective | |
Prior to USMI’s cessation of trading, scheduled for March 18, 2015, the investment objective of USMI was for the daily changes in percentage terms of its shares’ per share NAV to reflect the daily changes in percentage terms of the SummerHaven Metals Index Total ReturnSM (the “SDMI”), less USMI’s expenses. The SDMI is owned and maintained by SHIM and calculated and published by the NYSE Arca. Futures contracts for the metals in the SDMI that are traded on the NYMEX, the LME and COMEX are collectively referred to herein as “Eligible Metals Futures Contracts.” The SDMI is comprised of 10 Eligible Metals Futures Contracts that are selected on a monthly basis based on quantitative formulas developed by SHIM. The Eligible Metals Futures Contracts that at any given time make up the SDMI 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 SHIM. | |
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 shares began trading on June 19, 2012 and ceased trading on March 18, 2015. USMI’s assets were liquidated by March 25, 2015. As of December 31, 2014, USMI held 2 Futures Contracts on the NYMEX, 73 Futures Contracts on the LME and 12 Futures Contracts on the COMEX, totaling 87 futures contracts. | |

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 the Related Public Funds’ combined net assets, (b) 0.0465% for the Related Public Funds’ combined net assets greater than $500 million but less than $1 billion, and (c) 0.035% once the Related Public Funds’ combined net assets exceed $1 billion. The annual minimum amount will not apply if the asset-based charge for all accounts in the aggregate exceeds $75,000. USCF also pays transaction fees ranging from $7 to $15 per transaction. | |||||||||||||
The Trust on behalf of each Trust Series 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”). On July 7, 2014, the Trust on behalf of each Trust Series entered into a Futures and Cleared Swaps Agreement with Wells Fargo Securities, LLC (“WFS”). WFS and Newedge are collectively referred to as the “Futures Commissions Merchant” or “FCM”. The agreements require the FCM 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 the FCM for each Trust Series’ account. In accordance with the agreement, the FCM 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 shares 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 shares as a result of a Redemption Basket. Such fees are also incurred when Futures Contracts and options on Futures Contracts are purchased or redeemed for the purpose of rebalancing the portfolio. Each Trust Series also incurs commissions to brokers for the purchase and sale of Futures Contracts, Other Commodity-Related Investments or short-term obligations of the United States of two years or less (“Treasuries”). | |||||||||||||

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 SHIM, 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, 2014, plus an annual fee of 0.06% of the average daily total net assets of each Trust Series. | |||||||||||||

Risks and Uncertainties [Abstract] | |
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. Cleared swaps are over-the-counter agreements that are eligible to be cleared by a clearinghouse, but are not traded on an exchange. A cleared swap is created when the parties to an off-exchange over-the-counter swap transaction agree to extinguish their OTC contract and replace with a cleared swap. Cleared swaps are intended to provide the efficiencies and benefits that centralized clearing or an exchange offers to traders of futures contracts, including credit risk intermediation and the ability to offset positions initiated with different counterparties. | |
The purchase and sale of futures contracts and options on futures contracts require margin deposits with a FCM. Additional deposits may be necessary for any loss on contract value. The Commodity Exchange Act requires a FCM to segregate all customer transactions and assets from the FCM’s proprietary activities. | |
Futures contracts 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. Buying and selling options on futures contracts exposes investors to the risks of purchasing or selling futures contracts. | |
All of the Futures Contracts held by each Trust Series were exchange-traded through December 31, 2014. The risks associated with exchange-traded contracts are generally perceived to be less than those associated with over-the-counter transactions since, in over-the-counter transactions, a party must rely solely on the credit of its respective individual counterparties. When each Trust Series enters into non-exchange traded contracts (including Exchange for Risk or EFR transactions), it is subject to the credit risk associated with counterparty non-performance. The credit risk from counterparty non-performance associated with such instruments is the net unrealized gain, if any, on the transaction. 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 FCM are considered commingled with all other customer funds, subject to the FCM’s segregation requirements. In the event of a FCM’s insolvency, recovery may be limited to a pro rata share of segregated funds available. It is possible that the recovered amount could be less than the total of cash and other property deposited. The insolvency of a FCM could result in the complete loss of a Trust Series’ assets posted with that FCM; 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 FCM. 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 share 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, 2014 and December 31, 2013, 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, 2014 and December 31, 2013, USCI held cash deposits and investments in Treasuries in the amounts of $792,207,276 and $494,440,076, respectively, with the custodian and FCM. As of December 31, 2014 and December 31, 2013, CPER held cash deposits and investments in Treasuries in the amounts of $3,066,521 and $2,166,695, respectively, with the custodian and FCM. As of December 31, 2014 and December 31, 2013, USAG held cash deposits and investments in Treasuries in the amounts of $2,365,241 and $2,328,626, respectively, with the custodian and FCM. As of December 31, 2014 and December 31, 2013, USMI held cash deposits and investments in Treasuries in the amounts of $2,120,591 and $2,248,304, 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. | |
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. | |

Fair Value Disclosures [Abstract] | ||||||||||||||||||||||
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. | ||||||||||||||||||||||

Subsequent Events | 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, other than noted below. | |
On January 14, 2015, Mr. Howard Mah, Management Director, Chief Financial Officer (Principal Accounting Officer), Secretary and Treasurer of USCF, sponsor of the United States Commodity Index Funds Trust, tendered his resignation effective as soon as the Board of Directors of USCF accepts and appoints a suitable replacement, but no later than the close of business July 15, 2015. In order to ensure an orderly transition, Mr. Mah will remain as the Management Director and Chief Financial Officer (Principal Accounting Officer) of USCF until such time. | |
On January 26, 2015, Mr. Nicholas D. Gerber was appointed Chief Executive Officer, President and Secretary of Concierge Technologies, Inc.

Summary Of Significant Accounting Policies (Policies) | 12 Months Ended |
Dec. 31, 2014 | |
Basis of Presentation | Basis of Presentation |
The financial statements have been prepared in conformity with GAAP as detailed in the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification. Each Trust Series is an investment company and follows the accounting and reporting guidance in FASB Topic 946. | |
Revenue Recognition | 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 (“FCM”) at the 90-day Treasury bill rate. In addition, each Trust Series earns income on funds held at the custodian and/or FCM at prevailing market rates earned on such investments. | |
Brokerage Commissions | Brokerage Commissions |
Brokerage commissions on all open commodity futures contracts are accrued on a full-turn basis. | |
Income Taxes | 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 2011. The tax benefit recognized is measured as the largest amount of benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement. De-recognition of a tax benefit previously recognized results in 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, 2014 for any Trust Series. | |
Trust Capital and Allocation of Income and Losses | Trust Capital and Allocation of Income and Losses |
Profit or loss shall be allocated among the shareholders of each Trust Series in proportion to the number of shares 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. | |
Creations and Redemptions | Creations and Redemptions |
Authorized Participants may purchase Creation Baskets or redeem Redemption Baskets only in blocks of 50,000 shares. Effective as of May 1, 2012, Authorized Participants may purchase Creation Baskets or redeem Redemption Baskets for USCI, CPER and USAG only in blocks of 50,000 shares at a price equal to the NAV of the shares calculated shortly after the close of the core trading session on the NYSE Arca on the day the order is placed. Prior to May 1, 2012, Authorized Participants could only purchase Creation Baskets or redeem Redemption Baskets for USCI, CPER and USAG in blocks of 100,000 shares. USMI was not available to the public until June 19, 2012, and from its inception of offering, Authorized Participants could only purchase Creation Baskets in blocks of 50,000 shares. | |
Each Trust Series receives or pays the proceeds from shares sold or redeemed within three business days after the trade date of the purchase or redemption. The amounts due from Authorized Participants are reflected in each Trust Series’ statements of financial condition as receivable for shares sold, and amounts payable to Authorized Participants upon redemption are reflected as payable for shares redeemed. | |

Each Trust Series’ per share NAV is calculated on each NYSE Arca trading day by taking the current market value of its total assets, subtracting any liabilities and dividing the amount by the total number of shares 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 Share | Net Income (Loss) Per Share |
Net income (loss) per share is the difference between the per share NAV at the beginning of each period and the per share NAV at the end of each period. The weighted average number of shares outstanding was computed for purposes of disclosing net income (loss) per weighted average share. The weighted average shares are equal to the number of shares outstanding at the end of the period, adjusted proportionately for shares added and redeemed based on the amount of time the shares were outstanding during such period. As of December 31, 2014, USCF held 5 shares of USCI, 40 shares of CPER, 5 shares of USAG and 5 shares of USMI. | |
Offering Costs | Offering Costs |
Offering costs incurred in connection with the registration of shares prior to the commencement of the offering are borne by USCF. Offering costs incurred in connection with the registration of additional shares 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 |
Cash equivalents include money market funds and overnight deposits or time deposits with original maturity dates of six months or less. | |
Reclassifications | Reclassifications |
Certain prior year amounts have been reclassified to conform to the current year presentation. | |
Use of Estimates | 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. | |
