Contracts and Agreements [Abstract] |
Contracts and Agreements | NOTE 4 — CONTRACTS AND AGREEMENTS US12NG is party to a marketing agent agreement, dated as of October 30, 2009, as amended from time to time, with the Marketing Agent and USCF, whereby the Marketing Agent provides certain marketing services for US12NG as outlined in the agreement. The fee of the Marketing Agent, which is borne by USCF, is equal to 0.06% on US12NG’s assets up to $3 billion and 0.04% on US12NG’s 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. US12NG is also party to a custodian agreement, dated November 3, 2009, as amended from time to time, with Brown Brothers Harriman & Co. (“BBH&Co.”) and USCF, whereby BBH&Co. holds investments on behalf of US12NG. USCF pays the fees of the custodian, which are determined by the parties from time to time. In addition, US12NG is party to an administrative agency agreement, dated November 3, 2009, as amended from time to time, with USCF and BBH&Co., whereby BBH&Co. acts as the administrative agent, transfer agent and registrar for US12NG. 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 US12NG 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 US12NG’s, USOF’s, USNG’s, US12OF’s, UGA’s, USDHO’s, USSO’s, USBO’s, USCI’s, CPER’s, USAG’s and USMI’s combined net assets, (b) 0.0465% for US12NG’s, USOF’s, USNG’s, US12OF’s, UGA’s, USDHO’s, USSO’s, USBO’s, USCI’s, CPER’s, USAG’s and USMI’s combined net assets greater than $500 million but less than $1 billion, and (c) 0.035% once US12NG’s, USOF’s, USNG’s, US12OF’s, UGA’s, USDHO’s, USSO’s, USBO’s, USCI’s, CPER’s, USAG’s and USMI’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. US12NG has entered into a brokerage agreement with UBS Securities LLC (“UBS Securities”). The agreement requires UBS Securities to provide services to US12NG in connection with the purchase and sale of Futures Contracts and Other Natural Gas-Related Investments that may be purchased and sold by or through UBS Securities for US12NG’s account. In accordance with the agreement, UBS Securities charges US12NG 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 US12NG issues units as a result of a Creation Basket, as well as fees incurred when selling Futures Contracts and options on Futures Contracts when US12NG 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. US12NG also incurs commissions to brokers for the purchase and sale of Futures Contracts, Other Natural Gas-Related Investments or Treasuries. During the nine months ended September 30, 2012, total commissions accrued to brokers amounted to $11,485. Of this amount, approximately $5,746 was a result of rebalancing costs and approximately $5,739 was the result of trades necessitated by creation and redemption activity. By comparison, during the nine months ended September 30, 2011, total commissions accrued to brokers amounted to $5,451. Of this amount, approximately $3,416 was a result of rebalancing costs and approximately $2,035 was the result of trades necessitated by creation and redemption activity. The increase in the total commissions accrued to brokers for the nine months ended September 30, 2012, as compared to the nine months ended September 30, 2011, was primarily a function of an increase in creation and redemption activity during the nine months ended September 30, 2012. As an annualized percentage of average daily total net assets, the figure for the nine months ended September 30, 2012 represents approximately 0.05% of average daily total net assets. By comparison, the figure for the nine months ended September 30, 2011 represented approximately 0.02% of 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. US12NG and the NYMEX entered into a licensing agreement on December 4, 2007, as amended on October 20, 2011, whereby US12NG was granted a non-exclusive license to use certain of the NYMEX’s settlement prices and service marks. Under the licensing agreement, US12NG and the Related Public Funds, other than USBO, USCI, CPER, USAG and USMI, pay the NYMEX an asset-based fee for the license, the terms of which are described in Note 3. US12NG expressly disclaims any association with the NYMEX or endorsement of US12NG by the NYMEX and acknowledges that “NYMEX” and “New York Mercantile Exchange” are registered trademarks of the NYMEX.
