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.

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.

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.

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.
