The Frontier Fund

Notes to Financial Statements (Unaudited)

1. Organization

The Frontier Fund, which is referred to in this report as the Trust, was formed on August 8, 2003, as a Delaware statutory trust. The Trust is a multi-advisor commodity pool, as described in Commodity Futures Trading Commission (the “CFTC”) Regulation § 4.10(d)(2). The Trust has authority to issue separate series, or each, a Series, of units of beneficial interest (the “Units”) pursuant to the requirements of the Delaware Statutory Trust Act, as amended (the “Trust Act”). The assets of each Series are valued and accounted for separately from the assets of other Series. The Trust is not registered as an investment company under the Investment Company Act of 1940, as amended (the “Investment Company Act”). It is managed by its Managing Owner, Equinox Fund Management, LLC.

Purchasers of Units are limited owners of the Trust (“Limited Owners”) with respect to beneficial interests of the Series’ Units purchased. The Trust Act provides that, except as otherwise provided in the amended and restated declaration of trust and trust agreement of the Trust dated as of August 8, 2003, by and among the Managing Owner, Wilmington Trust Company as trustee and the unitholders from time to time (the “Trust Agreement”), unitholders in a Delaware statutory trust will have the same limitation of liability as do stockholders of private corporations organized under the General Corporation Law of the State of Delaware. The Trust Agreement confers substantially the same limited liability, and contains the same limited exceptions thereto, as would a limited partnership agreement for a Delaware limited partnership engaged in like transactions as the Trust. In addition, pursuant to the Trust Agreement, the Managing Owner of the Trust is liable for obligations of a Series in excess of that Series’ assets. Limited Owners do not have any such liability. The Managing Owner will make contributions to Series of the Trust necessary to maintain at least a 1% interest in the aggregate capital, profits and losses of all Series.

The Trust has been organized to pool assets of investor funds for the purpose of trading in the United States (“U.S.”) and international markets for currencies, interest rates, stock indices, agricultural and energy products, precious and base metals and other commodities. The Trust may also engage in futures contracts, forwards, option contracts and other interest in derivative instruments, including swap contracts (“Swaps”).

The Trust has eleven (11) separate and distinct Series of Units issued and outstanding: Frontier Diversified Series, Frontier Dynamic Series (closed to outside investors effective July 15, 2011 and existing outside investors liquidated as of July 15, 2011), Frontier Long/Short Commodity Series, Frontier Masters Series, Balanced Series, Berkeley/Graham/Tiverton Series (formerly Campbell/Graham/Tiverton Series), Currency Series, Long Only Commodity Series, Managed Futures Index Series, Winton Series and Winton/Graham Series (each a “Series” and collectively, the “Series”). The Trust may issue additional Series of Units.

The Trust, with respect to each Series:

• engages in the speculative trading of a diversified portfolio of futures, forward (including interbank foreign currencies), options contracts and other derivative instruments (including swap contracts), and may, from time to time, engage in cash and spot transactions;

• allocates funds to a limited liability trading company or companies (“Trading Company”). Except as otherwise described in these notes, each Trading Company has one-year renewable contracts with its own independent commodity trading advisor(s), or each, a Trading Advisor, that will manage all or a portion of such Trading Company’s assets and make the trading decisions for the assets of each Series vested in such Trading Company. Each Trading Company will segregate its assets from any other Trading Company;

• maintains separate, distinct records for each Series, and accounts for the assets of each Series separately from the other Series;

• calculates the Net Asset Value (“NAV”) of its Units for each Series separately from the other Series;

• has an investment objective of increasing the value of each Series’ Units over the long term (capital appreciation), while controlling risk and volatility; further, to offer exposure to the investment programs of individual Trading Advisors and to specific instruments (currencies);

32

• maintains each Series of Units in three or six sub-classes—Class 1, Class 1a, Class 2, Class 2a, Class 3, and Class 3a. Investors who have purchased Class 1 or Class 1a Units of any Series are charged a service fee of up to three percent (3.0%) annually of the NAV of each Unit purchased, for the benefit of Selling Agents selling such Class 1 or Class 1a Units. The initial service fee, which is amortized monthly at an annual rate of up to three percent (3.0%) of the average daily NAV of Class 1 or Class 1 a of such Series, is prepaid to Equinox Fund Management, LLC (the “Managing Owner”) by each Series, and paid to the selling agents by the Managing Owner in the month following sale; provided, however, that investors who redeem all or a portion of their Class 1 or Class 1 a Units of any Series during the first twelve (12) months following the effective date of their purchase are subject to a redemption fee of up to three percent (3.0%) of the NAV at which such investor redeemed to reimburse the Managing Owner for the then-unamortized balance of the prepaid initial service fee. With respect to Class 2 and Class 2a Units of any Series, the Managing Owner pays an ongoing service fee to Selling Agents of up to one half percent (0.5%) annually of the NAV of each Class 2 or Class 2a Unit (of which 0.25% will be charged to Limited Owners holding Class 2 Units of the Frontier Diversified Series, Frontier Dynamic Series and Frontier Masters Series or Class 2a Units of the Frontier Long/Short Commodity Series) sold until such Class 2 or Class 2a Units which are subject to the fee limitation are reclassified as Class 3 or Class 3a Units of the applicable Series. The Managing Owner may also pay Selling Agents certain additional fees and expenses for administrative and other services rendered and expenses incurred by such Selling Agents; and

• all payments made to Selling Agents who are members of the Financial Industry Regulatory Authority, Inc. (“FINRA”) and their associated persons that constitute underwriting compensation will be subject to the limitations set forth in Rule 2310(b)(4)(B)(ii) (formerly Rule 281 0(b)(4)(B)(ii)) of the Conduct Rules of FINRA (“Rule 2310”). An investor’s Class 1 Units or Class 2 Units of any Series, or Class 1a Units or Class 2a Units of the Frontier Long/Short Commodity Series or Balanced Series will be classified as Class 3 or Class 3a Units of such Series, as applicable, when the Managing Owner determines that the fee limitation set forth in Rule 2310 with respect to such Units has been reached or will be reached. No service fees are paid with respect to Class 3 or Class 3a Units. Units of any Class in a Series may be redeemed, in whole or in part, on a daily basis, at the then current NAV per Unit for such Series on the day of the week after the date the Managing Owner is in receipt of a redemption request for at least one (1) Business Day to be received by the Managing Owner prior to 4:00 PM in New York.

The assets of any particular Series include only those funds and other assets that are paid to, held by or distributed to the Trust on account of and for the benefit of that Series. Under the “Inter-Series Limitation on Liability” expressly provided for under Section 3804(a) of the Trust Act, separate and distinct records of the cash and equivalents, although pooled for maximizing returns, is maintained in the books and records of each Series.

As of September 30, 2011, each of the Long Only Commodity Series, Managed Futures Index Series and Winton Series has invested a portion of its assets in a single Trading Company. A single Trading Advisor manages 100% of the assets invested in each such Trading Company, except the Trading Company for the Long Only Commodity Series which allocates assets only to Swaps. The Currency Series invests a portion of its assets in a single Trading Company, which allocates assets to one Trading Advisor and one Swap. Each of the Frontier Diversified Series, Frontier Long/Short Commodity Series, Frontier Masters Series, Balanced Series, Berkeley/Graham/Tiverton Series, and Winton/Graham Series have invested a portion of its assets in several different Trading Companies and have multiple Trading Advisors that manage the assets invested in such Trading Companies.

In November 2010, the Berkeley/Graham/Tiverton Series invested a portion of its assets in Berkeley Quantitative Colorado Fund, LLC, an unaffiliated company, managed by an affiliate of Berkeley Quantitative L.P. Through this investment, Berkeley Quantitative L.P. became a commodity trading advisor to the Series.

During July, 2011, Currency Series liquidated its interest in an option basket and realized a decrease in fair value greater than had previously been recorded as unrealized loss. The Managing Owner determined to make a one time administrative adjustment by payment to the Currency Series of $390,589 to reimburse the effect of the loss on the investors in the series, exclusive of the inter-series payables’ interests, recorded in the Statements of Operations as Net increase from payments by managing owner.

2. Significant Accounting Policies

The following are the significant accounting policies of the Trust.

Basis of Presentation—The Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) is now FASB’s officially recognized source of authoritative U.S. generally accepted accounting principles (“GAAP”) applicable to all public and non-public non-governmental entities, superseding FASB, American Institute of Certified Public Accountants, Emerging Issues

33

Task Force and related literature. Rules and interpretive releases of the SEC under the authority of federal securities laws are also sources of authoritative GAAP for Securities and Exchange Commission (“SEC”) registrants. All other accounting literature is considered non-authoritative. Existing GAAP prior to the effective date of the ASC was not altered in compilation of the ASC. Citing particular content in the ASC involves specifying the unique numeric path to the content through the Topic, Subtopic, Section and Paragraph structure.

These financial statements should be read in conjunction with the audited financial statements and notes thereto included in our 2010 Annual Report on Form 10-K as filed with the SEC.

Consolidation—The Series, through investing in the Trading Companies, authorize certain Trading Advisors to place trades and manage assets at pre-determined investment levels. The Trading Companies were organized by the Managing Owner for the purpose of investing in commodities interests and derivative instruments, and have no operating income or expenses, except for trading income and expenses, all of which is allocated to the Series. Trading Companies in which a Series has a controlling and majority equity interest are consolidated by such Series. Investments in Trading Companies in which a Series does not have a controlling and majority interest are accounted for under the equity method, which approximates fair value. The equity interest held by Series of the Trust is shown as investments in unconsolidated trading companies in the statements of financial condition. The income or loss attributable thereto in proportion of investment level is shown in the statements of operations as equity in earnings/(loss) from unconsolidated trading companies.

Investments in Trading Companies in which a Series does not have a controlling or majority interest are carried in the statements of financial condition of such Series using the equity method of accounting, which approximates fair value. Fair value represents the proportionate share of the Series interest in the NAV in a Trading Company.

The financial statements of the Frontier Diversified Series include the assets, liabilities and earnings of its wholly-owned trading company, Frontier Trading Company X, LLC.

Included in the financial statements of the Frontier Long/Short Commodity Series are the assets and liabilities of its majority owned trading company; Frontier Trading Company VII, LLC, as well as the earnings of Trading Company VII, LLC and from September 28, 2011 through September 30, 2011.

The financial statements of the Frontier Masters Series include the assets, liabilities and earnings of its majority-owned trading company, Frontier Trading Company XXI, LLC which began trading operations on March 1, 2011.

The financial statements of the Balanced Series include the assets and liabilities of its wholly-owned trading company, Frontier Trading Company XII, LLC, as well as the earnings of Trading Company XII from July 18, 2011 through September 30, 2011. The financial statements of the Balanced Series also include the assets, liabilities and earnings of its majority-owned Trading Companies; Frontier Trading Company I, LLC, Frontier Trading Company IX, LLC, Frontier Trading Company XV, LLC and Frontier Trading Company XVII, LLC. Trading Company XVII, LLC began trading operations on July 5, 2011. Also included in the financial statements of the Balanced Series are the assets and liabilities of its majority owned Trading Company; Frontier Trading Company XIV, LLC, as well as the earnings of Trading Company XIV, LLC from June 20, 2011 through September 30, 2011.

The Berkeley/Graham/Tiverton Series has an investment in the Berkeley Quantitative Colorado Fund, LLC. The Berkeley Quantitative Colorado Fund, LLC is not consolidated into the financial statements of the Berkeley/Graham/Tiverton Series because the Trust has no control or transparency over the operations of the Trading Company. This investment is on the statements of financial condition as investment in Berkeley Quantitative Colorado Fund, LLC and any changes in fair value shown are shown on the statements of operations as net unrealized gain/(loss) on investment in Berkeley Quantitative Colorado Fund, LLC.

The financial statements of the Currency Series include the earnings of Frontier Trading Company III, LLC through July 15, 2011, at which time the investments in Trading Company III, LLC were liquidated.

The financial statements of the Long Only Commodity Series include the assets, liabilities and earnings of its wholly- owned trading company, Frontier Trading Company VIII, LLC.

The financial statements of the Winton/Graham Series include the earnings of Frontier Trading Company V, LLC through June 17, 2011.

Use of Estimates—The preparation of financial statements in conformity with GAAP may require the Managing Owner to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. The valuation of swap contracts requires significant estimates as well as the valuation of certain other investments. Please refer to Note 3 for discussion of valuation methodology.

34

Cash and Cash Equivalents—Cash and cash equivalents include cash and overnight investments in interest-bearing demand deposits held at banks with maturities of three months or less.

Interest Income—Aggregate interest income from all sources, including assets held at Futures Commission Merchants (“FCM”), up to two percentage points of the aggregate percentage yield (annualized) is paid to the Managing Owner by the Balanced Series (Class 1 and Class 2 only), Berkeley/Graham/Tiverton Series, Currency Series, Winton Series and Winton/Graham Series. For the Frontier Diversified Series, Frontier Dynamic Series, Frontier Long/Short Commodity Series, Frontier Masters Series, Balanced Series (Class 1a, Class 2a and Class 3a only), Long Only Commodity Series and Managed Futures Index Series, 20% of the total interest allocated to each Series is paid to the Managing Owner. All interest not paid to the Managing Owner is interest income to the Series.

U.S. Treasury Securities, custom time deposits and certain demand deposits are pooled for purposes of maximizing returns on these assets to investors of all Series. Interest income from pooled cash management assets is recognized on the accrual basis and allocated daily to each Series based upon its daily proportion of ownership of the pool. Interest income from demand deposits of the Series is allocated to the respective Series in proportion to their daily NAV.

U.S. Treasury Securities—U.S. Treasury Securities are allocated to all Series based on each Series’ percentage ownership in the pooled cash management assets as of the reporting date. They are reported at fair value as Level 1 inputs under ASC 820, Fair Value Measurements and Disclosures (“ASC 820”). The Trust values U.S. Treasury Securities at fair value and records the daily change in value in the statements of operations as net unrealized gain/(loss) on U.S. Treasury securities. Accrued interest is reported on the statements of financial condition as interest receivable.

Custom Time Deposits—Custom time deposits are structured deposit agreements with U.S. Bank National Association that earn a guaranteed fixed interest rate between 2.17% and 3.75% , mature nine months from the deposit date and are subject to automatic six-month rollovers through October 2013. Custom time deposits were purchased on September 15, 2009, October 21, 2008 and October 30, 2008. Interest is paid monthly or at least every nine months. Unscheduled withdrawals will be subject to certain penalties and other costs of up to 1.0% of the amount deposited if withdrawn within the first nine months from the deposit date. The withdrawal fee is set at 0.225% for the period from nine months to one year subsequent to the deposit date and decreases by .05% increments for each year thereafter through the maturity date. Custom time deposits are allocated to each Series based on their percentage ownership in the pooled cash management assets as of the reporting date. The Trust values the custom time deposits at face value plus accrued interest as it is considered a deposit account under paragraph 7.50 of the Investment Company Audit Guide, and accordingly, this deposit is not subject to ASC 820.

Credit Default Swaps—The Trust invests in credit default swaps for the purpose of mitigating part of the risk of concentration of deposits with U.S. Bank National Association to other major financial institutions. See Note 4. Credit Default Swaps are allocated to each Series based on their percentage ownership in the pooled cash management assets as of the reporting date. Credit Default Swaps are reported at fair value based upon daily valuations provided by a third party pricing service. The Series record the daily change in fair value in the statements of operations as net unrealized gain/(loss) on swap contracts.

Receivable From Futures Commission Merchants—The Trust deposits assets with a FCM subject to CFTC regulations and various exchange and broker requirements. Margin requirements are satisfied by the deposit of cash with such FCM. The Trust earns interest income on its assets deposited with the FCM.

Investment Transactions—Futures, options on futures, forward and swap contracts are recorded on a trade date basis and realized gains or losses are recognized when contracts are settled. Unrealized gains or losses on open contracts (the difference between contract trade price and market price) are reported in the statements of financial condition as a net unrealized gain or loss, as there exists a right of offset of unrealized gains or losses in accordance with FASB ASC 210, Balance Sheet (“ASC 210”).

Any change in net unrealized gain or loss from the preceding period is reported in the statements of operations. Fair value of exchange-traded contracts is based upon exchange settlement prices. Fair value of non-exchange-traded contracts is based on third party quoted dealer values on the interbank market. For U.S. Treasury securities, interest is recognized in the period earned and the instruments are marked-to-market daily based on third party information. Custom time deposits are valued at face value plus accrued interest and the interest income is recognized in the period earned. Transaction costs are recognized as incurred and reflected separately in the statements of operations.

Allocation of Earnings—Each Series of the Trust maintains three or six classes of Units—Class 1, Class 2, Class 3, Class 1a, Class 2a and Class 3a). All classes have identical voting, dividend, liquidation and other rights and the same terms and conditions, except that fees charged to a Class or Series differ as described below. Revenues, expenses (other than expenses attributable to a specific class), and realized and unrealized trading gains and losses of each Series are allocated daily to Class 1, Class 1a, Class 2, Class 2a, Class 3 and Class 3a Units based on each Class’ respective owners’ capital balances.

Each Series allocates funds to an affiliated Trading Company, or Companies, of the Trust. Each Trading Company allocates all of its daily trading gains or losses to the Series in proportion to each Series’ ownership interest in the Trading Company, adjusted on a daily

35

basis. As of September 30, 2011, the value of all open contracts and cash held at clearing brokers is similarly allocated to the Series in proportion to each Series’ funds allocated to the Trading Company, or Companies.

Inter-Series Receivables/Payables—The Balanced Series, for the purposes of diversification of investments and trading advisors through the other Series’ access to trading companies in which the Balanced Series did not have a direct interest, advanced funds to the Currency Series and the Frontier Dynamic Series. The amount of the funds advanced by the Balanced Series to each of the Currency Series and the Frontier Dynamic Series participated on a pari passu basis with Class 2 Units of such investee Series. The Balanced Series and investee Series reflected the changes in values of these investments as “net change in inter-series receivables/payables” in the statements of operations. The Balanced Series was subject to the same allocations of income and fees as the Limited Owners of such Series. As a result of fees charged by the investee Series, fees were not charged by the Balanced Series on the capital allocated to advances in affiliated Series. The Managing Owner monitored such allocations so that aggregate fees of the investee Series on the Balanced Series advances did not exceed the allowable fees of the Balanced Series as provided in the Trust’s Prospectus. Interest was not credited to the Balanced Series on the capital allocated to its inter-series advances to avoid the duplication of interest charged or received. These investments were liquidated during the third quarter of 2011.

Payments by the Managing Owner — The Trust may make discretionary payments to a Series related to a variety of factors, including investment losses to reimburse the effect of a loss on a portfolio investment which has been caused by a situation outside the Trust’s, or it’s affiliates’, direct control. Such payments will be made on a discretionary basis and will be disclosed in the statement of operations as a net increase from payments by managing owner. These payments are in accordance with the Trust agreement on a discretionary basis as determined by the Managing Owner.

Investments and Swaps—The Trust records investment transactions on a trade date basis and all investments are recorded at fair value in its financial statements, with changes in fair value reported as a component of realized and unrealized gains/(losses) on investments in the statements of operations. Certain Series of the Trust strategically invest a portion or all of their assets in total return Swaps, selected at the discretion of the Managing Owner. Swaps are privately negotiated contracts designed to provide investment returns linked to those produced by one or more underlying investment products or indices. In a typical Swap, two parties agree to exchange the returns (or differentials in rates of return) earned or realized on one or more particular predetermined investments or instruments. The gross returns to be exchanged or “swapped” between the parties are calculated with respect to a “notional amount” (i.e., the amount of value of the underlying asset used in computing the particular interest rate, return, or other amount to be exchanged) in a particular investment, or in a “basket” of securities. The valuation of swap contracts requires significant estimates. Swap contracts utilizing Level 2 inputs are reported at fair value based on daily reports from the swap counterparty that are corroborated against independent valuation/rate of return information published and available on a daily recurring frequency. Other Swap Contracts are reported utilizing Level 3 Inputs. Swap Contracts are reported at fair value based upon a weekly indicative value that is calculated by management using bid/ask prices from the counterparty. This fair value is corroborated by a daily range of valuations provided by a third party pricing service. The third party pricing service utilizes a Black Scholes pricing model with input adjustments factoring in volatility and liquidity of the instruments. All valuation processes are monitored by the valuation committee of the Managing Owner.

Income Taxes—The Trust applies the provisions of ASC 740 Income Taxes (“ASC 740”), which provides guidance for how uncertain tax positions should be recognized, measured, presented and disclosed in the financial statements. This interpretation also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods and disclosure. ASC 740 requires the evaluation of tax positions taken or expected to be taken in the course of preparing the Trust’s financial statements to determine whether the tax positions are “more-likely-than-not” of being sustained by the applicable tax authority. Tax positions with respect to tax at the Trust’s level not deemed to meet the “more-likely-than-not” threshold would be recorded as a tax benefit or expense in the current year. The Managing Owner has concluded there is no tax expense, interest or penalties to be recorded by the Trust for the year ended December 31, 2010. The 2008 through 2010 tax years generally remain subject to examination by U.S. federal and most state tax authorities.

In the opinion of the Managing Owner, (i) the Trust is treated as a partnership for Federal income tax purposes and, assuming that at least 90% of the gross income of the Trust constitutes “qualifying income” within the meaning of Section 7704(d) of the Code, the Trust is not a publicly traded partnership treated as a corporation, and (ii) the discussion set forth in the Prospectus under the heading “Federal Income Tax Consequences” correctly summarizes the material Federal income tax consequences as of the date of the Prospectus to potential U.S. Limited Owners of the purchase, ownership and disposition of Units of the Trust.

Fees and Expenses—All management fees, incentive fees, service fees and trading fees of the Trust are paid to the Managing Owner. It is the responsibility of the Managing Owner to pay all Trading Advisor management and incentive fees, Selling Agent Service fees and all other operating expenses and continuing offering costs of the Trust.

Service Fees—The Trust maintains each Series of Units in three or six sub-classes—Class 1, Class 1a, Class 2, Class 2a, Class 3, and Class 3a. Investors who have purchased Class 1 or Class 1a Units of any Series are charged a service fee of up to three percent (3.0%) annually of the NAV of each Unit purchased, for the benefit of selling agents selling such Class 1 or Class 1a Units. The initial service fee, which is amortized monthly at an annual rate of up to three percent (3.0%) of the average daily NAV of Class 1 or Class 1a of such Series, is prepaid to the Managing Owner by each Series, and paid to the selling agents by the Managing Owner in the month following sale; provided, however, that investors who redeem all or a portion of their Class 1 or Class 1a Units of any Series during the first twelve (12) months following the effective date of their purchase are subject to a redemption fee of up to three percent (3.0%) of the NAV at which such investor redeemed to reimburse the Managing Owner for the then-unamortized balance of the prepaid initial service fee. With respect to Class 2 and Class 2a Units of any Series, the Managing Owner pays an ongoing service fee

36

to Selling Agents of up to one half percent (0.5%) annually of the NAV of each Class 2 or Class 2a Unit (of which 0.25% will be charged to Limited Owners holding Class 2 Units of the Frontier Diversified Series, Frontier Dynamic Series and Frontier Masters Series or Class 2a Units of the Frontier Long/Short Commodity Series) sold until such Class 2 or Class 2a Units which are subject to the fee limitation are reclassified as Class 3 or Class 3a Units of the applicable Series for administrative purposes. The Managing Owner may also pay Selling Agents certain additional fees and expenses for administrative and other services rendered and expenses incurred by such Selling Agents.

These service fees are part of the offering costs of the Trust, which include registration and filing fees, legal and blue sky expenses, accounting and audit, printing, marketing support and other offering costs which are born by the Managing Owner. With respect to the service fees, the initial service fee (for the first 12 months) relating to a purchase of Class 1 and Class 1a Units by an investor is prepaid by the Managing Owner to the relevant selling agent in the month following such purchase and is reimbursed for such payment by the Series monthly in arrears in an amount based upon a corresponding percentage of NAV, calculated daily. Consequently, the Managing Owner bears the risk of the downside and enjoys the benefit of the upside potential of any difference between the amount of the initial service fee prepaid by it and the amount of the reimbursement thereof, which may result from variations in NAV over the following 12 months.

Pending Owner Additions—Funds received for new subscriptions and for additions to existing owner interests are recorded as capital additions at the NAV per unit of the second business day following receipt.

Recently Adopted Accounting Pronouncements—In January 2010, FASB issued Accounting Standards update No. 2010-06 (“ASU 2010-06”) for improving disclosure about fair value measurements. ASU 2010-06 adds new disclosure requirements about transfers into and out of Levels 1 and 2 and separate disclosures about purchases, sales, issuances and settlements in the reconciliation for fair value measurements using significant unobservable inputs (Level 3). It also clarifies existing disclosure requirements relating to the levels of disaggregation for fair value measurement and inputs and valuation techniques used to measure fair value. The amended guidance is effective for financial statements for fiscal years and interim periods beginning after December 15, 2009 except for disclosures about purchases, sales, issuances and settlements in the roll forward of activity in Level 3 fair value measurements, which are effective for fiscal years beginning after December 15, 2010 and for interim periods within those fiscal years. As this update is disclosure related, adoption of ASU 2010-06 on January 1, 2011 did not have a material impact on the Trust’s statement of financial condition, results of operations or cash flows.

Recently Issued Accounting Pronouncements—In May 2011, the FASB issued ASU No. 2011-04 which provides guidance pertaining to fair value measurement that included a common definition of fair value and information to assist reporting entities to measure and disclose fair value with regards to U.S. GAAP and International Financial Reporting Standards (“IFRS”) convergence issues. This guidance becomes effective for interim and annual periods beginning on or after December 15, 2011, with early adoption prohibited. We are currently evaluating the impact that this accounting guidance may have on the Trust’s statement of financial condition, results of operations or cash flows.

Reclassification—Certain amounts in the 2010 financial statements have been reclassified to conform to the 2011 presentation. None of the reclassifications had an impact of the NAV of any of the Series.

Subsequent Events—The Trust follows the provisions of FASB ASC 855, Subsequent Events, which establishes general standards of accounting for and disclosure of events that occur after the balance sheet date but before financial statements are issued. Refer to Note 11.

3. Fair Value Measurements

In connection with the valuation of investments the Series apply ASC 820. ASC 820 provides clarification that when a quoted price in an active market for the identical asset or liability is not available, a reporting entity is required to measure fair value using certain techniques. ASC 820 also clarifies that when estimating the fair value of an asset or liability, a reporting entity is not required to include a separate input or adjustment to other inputs relating to the existence of a restriction that prevents the transfer of an asset or liability. ASC 820 also clarifies that both a quoted price in an active market for the identical asset or liability at the measurement date and the quoted price for the identical asset or liability when traded as an asset in an active market when no adjustments to the quoted price of the asset are required are Level 1 fair value measurements.

Level 1 Inputs

Unadjusted quoted prices in active markets for identical financial assets that the reporting entity has the ability to access at the measurement date.

37

Level 2 Inputs

Inputs other than quoted prices included in Level 1 that are observable for the financial asset or liabilities, either directly or indirectly. These might include quoted prices for similar financial assets in active markets, quoted prices for identical or similar financial assets in markets that are not active, inputs other than quoted prices that are observable for the financial asset or inputs that are derived principally from or corroborated by market data by correlation or other means.

Level 3 Inputs

Unobservable inputs for determining the fair value of financial assets that reflect an entity’s own assumptions about the assumptions that market participants would use in pricing the financial asset.

The Trust uses the following methodologies to value instruments within its financial asset portfolio at fair value:

Trading Securities. These instruments include U.S. Treasury securities and open trade equity positions (futures contracts and currency forwards) that are actively traded on public markets with quoted pricing for corroboration. U.S. Treasury securities, futures contracts, and currency forwards are reported at fair value using Level 1 inputs. Trading securities instruments further include open trade equity positions (trading options) that are quoted prices for identical or similar assets that are not traded on active markets. Trading options are reported at fair value using Level 2 inputs.

Swap Contracts. Certain Series of the Trust strategically invest a portion or all of their assets in total return Swaps, selected at the direction of the Managing Owner. Each Series also owns a portion of the Credit Default Swaps (“CDS”) based upon ownership percentages of the cash management pool. Swaps are privately negotiated contracts designed to provide investment returns linked to those produced by one or more investment products or indices. In a typical Swap, two parties agree to exchange the returns (or differentials in rates of return) earned or realized on one or more particular predetermined investments or instruments. The gross returns to be exchanged or “swapped” between the parties are calculated with respect to a “notional amount” (i.e., the amount of value of the underlying asset used in computing the particular interest rate, return, or other amount to be exchanged) in a particular investment, or in a “basket” of securities. The valuation of swap contracts requires significant estimates. Certain Swap contracts are reported utilizing Level 2 inputs. These Swap contracts are reported at fair value based on daily reports from the swap counterparty that may be corroborated against independent valuation/rate of return information published and available on a daily recurring frequency. Swap contracts utilizing Level 2 inputs are reported at fair value based on daily reports from the swap counterparty that may be corroborated against independent valuation/rate of return information published and available on a daily recurring frequency. Other Swap contracts are reported utilizing Level 3 Inputs. Swap Contracts are reported at fair value based upon a weekly indicative value that is calculated by management using bid/ask prices from the counterparty. This fair value is corroborated by a daily range of valuations provided by a third party pricing service. The third party pricing service utilizes a Black Scholes pricing model with input adjustments factoring in volatility and liquidity of the instruments. All valuation processes are monitored by the valuation committee of the Managing Owner.

Investment in Unconsolidated Trading Companies. This investment represents the fair value of the allocation of cash, futures, forwards, options and swaps to each respective Series relative to its trading allocations from unconsolidated Trading Companies. The Trust, under the same management as the Trading Companies, has access to the underlying positions of the Trading Companies. As such, the Series report investments in unconsolidated Trading Companies at fair value using the corresponding inputs of the underlying securities of the Trading Companies which results in the Series reporting the corresponding Level determination from the inputs of the Trading Company.

Investment in the Berkeley Quantitative Colorado Fund, LLC. Investment in Berkeley Quantitative Colorado Fund, LLC is valued based on the daily net asset value as reported by the managing member of the Berkeley Quantitative Colorado Fund, LLC. The reported net asset value represents fair value based on observable data such as ongoing redemption and/or subscription activity, which is reported as a Level 2 input.

Inter-Series Receivables and Payables. The Balanced Series, for the purposes of diversification of investments and trading advisors through the other Series’ access to Trading Companies in which the Balanced Series does not have a direct interest, advanced funds to the Currency Series and Frontier Dynamic Series. As of September 30, 2011, all inter-Series receivables and payables have been settled. Inter-Series receivables and payables were reported at fair value using Level 1 inputs.

The following table summarizes the instruments that comprise the Trust’s financial asset portfolio, by Series, measured at fair value on a recurring basis as of September 30, 2011 and December 31, 2010, segregated by the level of valuation inputs within the fair value hierarchy utilized to measure fair value:

4. Swaps

In addition to authorizing Trading Advisors to manage pre-determined investment levels of futures and forward contracts, certain Series of the Trust will strategically invest a portion or all of their assets in total return Swaps, selected at the direction of the Managing Owner. Total return Swaps are privately negotiated contracts designed to provide investment returns linked to those produced by one or more investment products or indices. In a typical total return Swap, two parties agree to exchange the returns (or differentials in rates of return) earned or realized on one or more particular predetermined investments or instruments. The gross returns to be exchanged or “swapped” between the parties are calculated with respect to a “notional amount” (i.e., the amount or value of the underlying asset used in computing the particular interest rate, return, or other amount to be exchanged) in a particular investment, or in a “basket” of securities.

Each Series invests in Credit Default Swaps (“CDS”) with highly-rated counterparties as part of its portfolio. CDSs are over-the-counter investment instruments designed to mitigate counterparty risk and generally pay upon the happening of a credit default of a counterparty. The CDS are allocated to each Series based on their percentage ownership in the pooled cash management assets at U.S. Bank National Association as of the reporting date. Approximately 23% of the Trust’s U.S. Bank National Association exposure is risk-hedged in this manner with BNP Paribas through March 20, 2012, and 15% with Societe Generale expiring from December 20, 2011 through March 20, 2012.

Each Series’ investment in Swaps will likely differ substantially over time due to cash flows, portfolio management decisions and market movements. For the Balanced Series, Currency Series, and Frontier Diversified Series, the Swaps serve to diversify the investment holdings of each Series and to provide access to programs and advisors that would not be otherwise available to the Series, and are not used for hedging purposes.

The Managing Owner follows a procedure in selecting well-established financial institutions which the Managing Owner, in its sole discretion, considers to be reputable, reliable, financially responsible and well established to act as swap counterparties. The procedure includes due diligence review of documentation on all new and existing financial institution counterparties prior to initiation of the relationship, and quarterly ongoing review during the relationship, to ensure that counterparties meet the Managing Owner’s minimum credit requirements, the counterparty average rating being no less than an investment grade rating as defined by the rating agencies. As of September 30, 2011, approximately 5.0% of the Trust’s assets were deposited with over-the-counter counterparties in order to initiate and maintain Swaps.

The Balanced Series, Currency Series and Frontier Diversified Series strategically invest assets in one or more Swaps linked to certain underlying investments or indices at the direction of the Managing Owner. The Trading Company in which the assets of these Series will be invested will not own any of the investments or indices referenced by any Swap entered into by these Series. In addition, neither the swap counterparty to the Trading Company of these Series nor any advisor referenced by any such Swap is a Trading Advisor to these Series.

The Long Only Commodity Series, through the Trading Company in which the assets of the Long Only Commodity Series have been allocated, have entered into various Swaps with one or more swap counterparties. The Swaps enable the Long Only Commodity Series to earn returns similar to returns (less the fees and expenses of the Long Only Commodities Series, including the expenses associated with the Swaps) of the Thompson Reuters/Jefferies CRB Index (the “RJ/CRB Index”), and the Jefferies Commodity Performance Index (the “JCPI”). Specifically, the Trading Company, which will hold the assets allocable to the Long Only Commodity Series, will enter into Swaps linked to the RJ/CRB Index and the JCPI at the direction of the Managing Owner.

The Trust has invested in the following Swaps as of September 30, 2011:

5. Investments in Unconsolidated Trading Companies

Investments in unconsolidated trading companies represent cash and open trade equity invested in the Trading Companies by each Series and cumulative trading profits or losses allocated to each Series by the Trading Companies. Trading Companies allocate trading profits or losses on the basis of the proportion of each Series’ capital allocated for trading to each respective Trading Company, which bears no relationship to the amount of cash invested by a Series in the Trading Company. The Trading Companies are valued using the equity method of accounting, which approximates fair value.

The following table summarizes the Balanced Series, Winton Series, Currency Series, Berkeley/Graham/Tiverton Series, Winton/Graham Series, Frontier Long/Short Commodity Series, Managed Futures Index Series, Frontier Diversified Series, and Frontier Masters Series investments in unconsolidated Trading Companies as of September 30, 2011 and December 31, 2010.

6. Transactions with Affiliates

The Managing Owner contributes funds to the Trust in order to have a 1% interest in the aggregate capital, profits and losses of all Series and in return will receive units designated as general units in the Series in which the Managing Owner invests such funds. The general units may only be purchased by the Managing Owner and may be subject to no advisory fees or advisory fees at reduced rates. Otherwise, the general units hold the same rights as the limited units. The Managing Owner is required to maintain at least a 1% interest (“Minimum Purchase Commitment”) in the aggregate capital, profits and losses of all Series so long as it is acting as the Managing Owner of the Trust. Such contribution was made by the Managing Owner before trading commenced for the Trust and will be maintained throughout the existence of the Trust, and the Managing Owner will make such purchases as are necessary to effect this requirement. Additionally, the Managing Owner agreed with certain regulatory bodies to maintain a 1% interest specifically in the Balanced Series Class 1 a Units and Balanced Series Class 2a Units, aggregated, and each of the Long Only Commodity Series, Frontier Long/Short Commodity Series, Managed Futures Index Series, Frontier Diversified Series, Frontier Dynamic Series and Frontier Masters Series. The 1% interest in these specific Series is included in computing the Minimum Purchase Commitment in aggregate capital. In addition to the General Units the Managing Owner receives in respect of its Minimum Purchase Commitment, the Managing Owner may purchase Limited Units in any Series as a Limited Owner. Principals of the Managing Owner or affiliates are allowed to own beneficial interests in the Trust, as well. All Units purchased by the Managing Owner are held for investment purposes only and not for resale. The Managing Owner may make purchases or redemptions at any time on the same terms as any Limited Owner. The Trust has and will continue to have certain relationships with the Managing Owner and its affiliates.

The Balanced Series had advanced funds to the Currency Series, Frontier Diversified Series, Frontier Dynamic Series and Frontier Masters Series for the purpose of investing in the respective Trading Company for such Series on behalf of the Balanced Series. All of these investments have been liquidated as of September 30, 2011.

On July 18, 2011, the Balanced Series reduced its inter-series advance to the Dynamic Series in exchange for ownership in a total return swap contract in the amount of $27,379,284 which approximated fair value in accordance with the Trust’s valuation policies at the date of transfer.

The following table summarizes the Balanced Series advances to and reductions from the Currency Series, Frontier Diversified Series, Frontier Dynamic Series and Frontier Masters Series of the Trust for the nine months ended September 30, 2011 and the year ended December 31, 2010.

(1) Balanced Series Inter-series receivables are corresponding Inter-series payables on the Statements of Financial Condition for the investee Series.

Expenses

Management Fees—Each Series of Units pays to the Managing Owner a monthly management fee equal to a certain percentage of such Series’ assets attributable to such Series (including notional assets), calculated on a daily basis. The annual rate of the management fee is 0.5% for the Balanced Series, 2.0% for the Winton Series, Currency Series, Long Only Commodity Series, Frontier Long/Short Commodity Series Class 1 a and Class 2a, Managed Futures Index Series, Frontier Diversified Series, Frontier Dynamic Series and Frontier Masters Series, 2.5% for the Winton/Graham Series and Berkeley/Graham/Tiverton Series, and 3.5% for the Frontier Long/Short Commodity Series Class 1 and Class 2. The Managing Owner may pay all or a portion of such management fees to the Trading Advisor(s) for such Series.

Trading Fees—In connection with each Series’ trading activities, the Frontier Long/Short Commodity Series (Classes 1, 2 and 3), Balanced Series, Currency Series, Berkeley/Graham/Tiverton Series, Long/Only Commodity Series, Managed Futures Index Series, Winton Series and Winton/Graham Series pays to the Managing Owner a trading fee, or FCM Fee, up to 0.75% of such Series’ NAV, calculated daily. The Frontier Diversified Series, Frontier Dynamic Series, Frontier Long/Short Commodity Series (Classes 1a and 2a) and Frontier Masters Series pays to the Managing Owner a trading fee, or FCM Fee, up to 2.25% and a custodial/due diligence fee of 0.12% of such Series’ NAV, calculated daily.

Incentive Fees—Some Series pay to the Managing Owner an incentive fee of a certain percentage of new net trading profits generated by such Series, monthly or quarterly. Because the Balanced Series, Winton/Graham Series, Berkeley/Graham/Tiverton Series, Currency Series and Frontier Long/Short Commodity Series may each employ multiple Trading Advisors, these Series will pay the

55

Managing Owner a monthly incentive fee calculated on a Trading Advisor by Trading Advisor basis. It is therefore possible that in any given period the Balanced Series or the Frontier Long/Short Commodity Series may pay incentive fees to the Managing Owner for one or more Trading Advisors while each of these Series as a whole experiences losses. The incentive fee is 25% for the Balanced Series and the Frontier Diversified Series and 20% for the Winton Series, Currency Series, Winton/Graham Series, Berkeley/Graham/Tiverton Series, Frontier Long/Short Commodity Series, Frontier Dynamic Series and Frontier Masters Series. There is no incentive fee for the Long Only Commodity Series or the Managed Futures Index Series. The Managing Owner may pay all or a portion of such incentive fees to the Trading Advisor(s) for such Series.

Service Fees—In addition, with respect to Class 1 and Class 1a Units of each Series, as applicable, the Series pays monthly or quarterly to the Managing Owner a service fee at an annualized rate, as described in more detail above, which the Managing Owner pays to selling agents of the Trust.

The following table summarizes fees earned by the Managing Owner for the three months ended September 30, 2011 and 2010.

With respect to the service fees, the initial service fee (for the first 12 months) relating to a purchase of Units by an investor is prepaid by the Managing Owner to the relevant selling agent in the month following such purchase and is reimbursed therefore by the Series monthly in arrears in an amount based upon a corresponding percentage of NAV, calculated daily. Consequently, the Managing Owner bears the risk and enjoys the benefit of the upside potential of any difference between the amount of the initial service fee prepaid by it and the amount of the reimbursement thereof, which may result from variations in NAV over the following 12 months. For the nine months ended September 30, 2011, amounts received or receivable from the Managing Owner for the difference in monthly service fees from the prepaid initial service fees were $2,752 for the Frontier Dynamic Series, $17 for the Long/Only Commodity Series and $9 for the Managed Futures Index Series. For the nine months ended September 30, 2011, amounts paid or owing the Managing Owner for the difference in monthly service fees from prepaid initial service fees were $27,761 for the Balanced Series, $17,533 for the Frontier Long/Short Commodity Series, $22,103 for the Frontier Diversified Series, $530 for the Currency Series, $5,509 for the Berkeley/Graham/Tiverton Series, $3,742 for the Winton/Graham Series, $7,838 for the Winton Series and $11,973 for the Frontier Masters Series.

Aggregate interest income from all sources, including assets held at clearing brokers, up to 2% (annualized) is paid to the Managing Owner by the Balanced Series (Class 1 and Class 2 only), Winton Series, Berkeley/Graham/Tiverton Series, Currency Series and Winton/Graham Series. For the Frontier Diversified Series, Frontier Dynamic Series, Frontier Long/Short Commodity Series, Frontier Masters Series, Balanced Series (Class 1a and Class 2a only), Long Only Commodity Series and Managed Futures Index Series 20% of the total interest allocated to each Series is paid to the Managing Owner. During the nine months ended September 30, 2011, and 2010 the Trust paid $7,197,876 and $7,573,585, respectively, of such interest income to the Managing Owner. Such expenses are not included in the statements of operations of the Series.

The Managing Owner pays to The Bornhoft Group Corporation, an affiliate of the Trust, a monthly fee of 0.25% (annualized) of the NAV of the Trust, for services in connection with the daily valuation of each Series and Class. The amount paid under this agreement was $429,634 and $514,050, respectively for the three months ended September 30, 2011 and 2010 and $1,483,875 and $1,472,121, respectively for the nine months ended September 30, 2011 and 2010.

(1) Interest income and expenses per unit are calculated by dividing these amounts by the average number of units outstanding during the period.

The net gain/(loss) on investments, net of non-controlling interests is a balancing amount necessary to reconcile the change in net asset value per unit with the other per unit information.

(2) Computed using average net assets outstanding during the period. An owner’s total returns may vary from the above returns based on the timing of contributions and withdrawals. Total returns are not annualized.

(3) Annualized

(4) Long Only Series Class 3 and Managed Futures Index Series Class 3 began trading operations on January 13, 2011.

(5) Formerly the Cambell/Graham/Tiverton Series.

(6) The Frontier Dynamic Series ceased trading operations on July 15, 2011 and redeemed all existing Units. The Series remains active. Net asset value per unit represents the liquidation value.

(7) For the three months ended September 30, 2011, 8.10% of the Currency Series’ Class 1 total return and 1.31% of the Currency Series’ Class 2 total return consists of a discretionary voluntary reimbursement by the managing owner for a realized investment loss. Excluding this item, total return would have been (11.79%) for Currency Series Class 1 and (1.90%) for Currency Series Class 2.

(1) Interest income and expenses per unit are calculated by dividing these amounts by the average number of units outstanding during the period.

The net gain/(loss) on investments, net of non-controlling interests is a balancing amount necessary to reconcile the change

in net asset value per unit with the other per unit information.

(2) Computed using average net assets outstanding during the period. An owner’s total returns may vary from the above returns based on the timing of contributions and withdrawals. Total returns are not annualized.

(3) Annualized

(4) Long Only Series Class 3 and Managed Futures Index Series Class 3 began trading operations on January 13, 2011.

(5) Formerly the Cambell/Graham/Tiverton Series.

(6) The Frontier Dynamic Series ceased trading operations on July 15, 2011 and redeemed all existing Units. The Series remains active. Net asset value per unit represents the liquidation value.

(7) For the nine months ended September 30, 2011, 6.97% of the Currency Series’ Class 1 total return and 2.40% of the Currency Series’ Class 2 total return consists of a discretionary voluntary reimbursement by the managing owner for a realized investment loss. Excluding this item, total return would have been (16.11%) for Currency Series Class 1 and (5.54%) for Currency Series Class 2.

9. Trading Activities and Related Risks

The purchase and sale of futures and options on futures contracts require margin deposits with Futures Commission Merchants (each, an “FCM”). Additional deposits may be necessary for any loss on contract value. The Commodity Exchange Act requires an FCM to segregate all customer transactions and assets from the FCM’s proprietary activities. A customer’s cash and other property (for example, U.S. Treasury bills) deposited with an FCM are considered commingled with all other customer funds subject to the FCM’s segregation requirements. In the event of an 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 term “off-balance sheet risk” refers to an unrecorded potential liability that, even though it does not appear on the statements of financial condition, may result in future obligation or loss in excess of the amount paid by the Series for a particular investment. Each Trading Company expects to trade in futures, options, forward and swap contracts and will therefore be a party to financial instruments with elements of off-balance sheet market and credit risk. In entering into these contracts, there exists a market risk that such contracts may be significantly influenced by market conditions, such as interest rate volatility, resulting in such contracts being less valuable. If the markets should move against all of the futures positions held by a Trading Company in respect of any Series at the same time, and if the Trading Advisor(s) of such Trading Company are unable to offset such futures interests positions, such Trading Company could lose all of its assets and the holders of Units of such Series would realize a 100% loss. The Managing Owner will seek to minimize market risk through real-time monitoring of open positions and the level of diversification of each Trading Advisor’s portfolio. It is anticipated that any Trading Advisor’s margin-to-equity ratio will typically not exceed approximately 35% although the actual ratio could be higher or lower from time to time.

In addition to market risk, trading futures, forward and swap contracts entails credit risk in that a counterparty will not be able to meet its obligations to a Trading Company. The counterparty for futures contracts traded in the United States and on most foreign exchanges is the clearinghouse associated with such exchange. In general, clearinghouses are backed by the corporate members of the clearinghouse who are required to share any financial burden resulting from the non-performance by one of their members and, as such, should significantly reduce this credit risk. In cases where the clearinghouse is not backed by the clearing members, like some foreign exchanges, it is normally backed by a consortium of banks or other financial institutions. Some non-U.S. exchanges, in contrast to U.S. exchanges, are principals’ markets in which performance is the responsibility only of the individual counterparty with whom the Trading Company has entered into the transaction, and not of the exchange or clearing corporation. In these kinds of markets, there is risk of bankruptcy or other failure or refusal to perform by the counterparty.

In the case of forward contracts traded on the interbank market and swaps, neither is traded on exchanges. The counterparty is generally a single bank or other financial institution, rather than a group of financial institutions; thus there may be a greater counterparty credit risk. The Managing Owner expects the Trading Advisors to trade only with those counterparties which it believes to be creditworthy. All positions of each Trading Company will be valued each day on a mark-to-market basis. There can be no assurance that any clearing member, clearinghouse or other counterparty will be able to meet its obligations to any Trading Company.

The Managing Owner has established procedures to actively monitor and minimize market and credit risks. The Limited Owners bear the risk of loss only to the extent of the market value of their respective investments and, in certain specific circumstances, distributions and redemptions received.

10. Indemnifications

The Trust has entered into agreements, which provide for the indemnification of futures clearing brokers, and commodity trading advisers, among others, against losses, costs, claims and liabilities arising from the performance of their individual obligations under such agreements, except for gross negligence or bad faith. The Trust has had no prior claims or payments pursuant to these agreements. The Trust’s individual maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Trust that have not yet occurred. However, based on experience the Trust expects the risk of loss to be remote.

11. Subsequent Events

Item 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Introduction

The following discussion and tables should be read in conjunction with our unaudited consolidated financial statements and notes thereto included in this quarterly report and our 2010 Annual Report on Form 10-K for the year ended December 31, 2010.

69

Overview

The Frontier Fund (the “Trust”), is a Delaware statutory trust formed on August 8, 2003. The Trust is a multi-advisor commodity pool, as described in CFTC Regulation § 4.10(d)(2). The Trust is authorized to issue multiple series (“Series”) of Units (the “Units”), pursuant to the requirements of the Trust Act. The assets of each Series are held and accounted for in separate and distinct records separately from the assets of other Series. The Trust is managed by Equinox Fund Management LLC (the “Managing Owner”), and its term will expire on December 31, 2053 (unless terminated earlier in certain circumstances).

The Trust, with respect to each Series of Units, engages in the speculative trading of a diversified portfolio of futures, forward (including interbank foreign currencies) and options contracts and other derivative instruments (including Swaps) and may, from time to time, engage in cash and spot transactions and allocates funds to an affiliated limited liability trading company (each a “Trading Company”). Each Trading Company has one-year renewable contracts with its own independent Trading Advisor(s) that will manage all or a portion of the applicable Trading Company’s assets, and make the trading decisions for the assets of each Series vested in such Trading Company (other than the Frontier Dynamic Series and the Long Only Commodity Series which allocate assets only to Swaps). The assets of each Trading Company will be segregated from the assets of each other Trading Company. The Trust has an investment objective of increasing the value of the Units over the long term (capital appreciation), while controlling risk and volatility; further, to offer exposure to the investment programs of individual Trading Advisors and to specific instruments (currencies).

As of September 30, 2011 the Trust had eleven separate Series of Units issued and outstanding: the Frontier Diversified Series, Frontier Dynamic Series (all of whose Units have been redeemed as of September 30, 2011, but the Series remains open), Frontier Long/Short Commodity Series, Frontier Masters Series, Balanced Series, Berkeley/Graham/Tiverton Series, Currency Series, Long Only Commodity Series, Managed Futures Index Series, Winton Series and Winton/Graham Series. Each Series of Units has between three and six separate classes issued and/or outstanding—Class 1, Class 2, Class 3, Class 1a, Class 2a, and Class 3a.

Critical Accounting Policies and Estimates

The financial statements of the Trust in this Quarterly Report on Form 10-Q have not been audited by an independent registered public accounting firm, but in the opinion of management, reflect all adjustments necessary for a fair presentation of the Trust’s financial position and results of operations. The financial statements have been prepared in accordance with generally accepted accounting principles (“GAAP”). These interim financial statements have been prepared in accordance with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X and serve to update the Trust’s 2010 Annual Report on Form 10-K (“Form 10-K”). These financial statements do not include all of the information and notes necessary to constitute a complete set of financial statements under GAAP applicable to annual periods. Accordingly, they should be read in conjunction with the financial information contained in the Form 10-K. In the opinion of management, all adjustments necessary for a fair presentation have been included. The results of operations for the interim periods disclosed herein are not necessarily indicative of results that may be expected for the full year or any future period.

The Trust’s other significant accounting policies are described in detail in Note 2 of the financial statements.

Investment Transactions and Valuation

The Managing Owner has evaluated the nature and type of transactions processed and estimates that it makes in preparing the Trust’s financial statements and related disclosures and has adopted Accounting Standard Codification ( “ASC”) 820, Fair Value Measurements and Disclosure, and implemented the framework for measuring fair value for assets and liabilities.

The Trust utilizes valuation techniques that are consistent with the market approach per the requirement of ASC 820 for the valuation of futures (exchange traded) contracts, forward (non-exchange traded) contracts, option contracts, swap contracts and other non-cash assets. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities. The Trust applies the valuation techniques in a consistent manner for each asset or liability. The Trust records all investments at fair value in its Statements of Financial Condition, with changes in fair value reported as a component of net gain/(loss) on investments in the Statements of Operations.

Inputs to valuation techniques refer to the assumptions that market participants would use in pricing the assets or liabilities. Inputs may be observable, meaning those that reflect the assumptions market participants would use in pricing the financial asset or liability based on market data obtained from independent sources, or unobservable, meaning those that reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the financial asset or liability based on the best information available in the circumstances.

In addition, the Trust monitors counterparty credit risk and incorporates any identified risk factors when assigning input levels to underlying financial assets or liabilities. In that regard ASC 820 establishes a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical financial assets and the lowest priority to unobservable inputs. A full disclosure of the fair value hierarchy is presented in Note 3 of the financial statements—Fair Value Measurements.

70

Liquidity and Capital Resources

The Trust will raise additional capital only through the sale of Units offered pursuant to the continuing offering, and does not intend to raise any capital through borrowing. Due to the nature of the Trust’s business, it makes no capital expenditures and has no capital assets that are not operating capital or assets.

The Managing Owner is responsible for the payment of all of the ordinary expenses associated with the organization of the Trust and the offering of each Series of Units, except for the initial and ongoing service fee, if any, and no Series will be required to reimburse these expenses. As a result, 100% of each Series’ offering proceeds are initially available for that Series’ trading activities.

A portion of each Trading Company’s assets is used as margin to maintain that Trading Company’s forward currency contract positions, and another portion is deposited in cash in segregated accounts in the name of each Trading Company maintained for each Trading Company at the clearing brokers in accordance with CFTC segregation requirements. At September 30, 2011, cash deposited at the clearing brokers was $67,309,977 for the Balanced Series, $83,085,859 for the Frontier Long/Short Commodity Series and $4,986,615 for the Frontier Masters Series. At December 31, 2010, cash deposited at the clearing brokers was $85,398,794 for the Balanced Series, $678,208 for the Currency Series and $11,090,076 for the Winton/Graham Series. The clearing brokers are expected to credit each Trading Company with approximately 80%-100% of the interest earned on its average net assets on deposit with the clearing brokers each month. Currently, with the Federal Funds target rate at 0.00% to 0.25%, this amount is estimated to be 0.00%. In an attempt to increase interest income earned, the Managing Owner also may invest the non-margin assets in U.S. government securities which include any security issued or guaranteed as to principal or interest by the U.S., or by a person controlled by or supervised by and acting as an instrumentality of the government of the U.S. pursuant to authority granted by Congress or any certificate of deposit for any of the foregoing, including U.S. treasury bonds, U.S. treasury bills and issues of agencies of the U.S. government, and certain cash items such as money market funds, certificates of deposit (under nine months) and time deposits. Aggregate interest income from all sources, including assets held at clearing brokers, up to 2% (annualized) is paid to the Managing Owner by the Balanced Series (Class 1 and Class 2 only), Winton Series, Berkeley/Graham/Tiverton Series, Currency Series, and Winton/Graham Series. For the Balanced Series (Class 1a and Class 2a only), Long Only Commodity Series, Frontier Long/Short Commodity Series and Managed Futures Index Series, 20% of the total interest allocated to each Series is paid to the Managing Owner.

Approximately 10% to 20% of the Trust’s assets are expected to be committed as required margin for futures contracts and forwards and options trading and held by the respective broker, although the amount committed may vary significantly. Such assets are maintained in the form of cash or U.S. treasury bills in segregated accounts with the futures broker pursuant to the Commodity Exchange Act and regulations there under. Approximately 2% to 6% of the Trust’s assets are expected to be deposited with over-the-counter counterparties in order to initiate and maintain forward and swap contracts. Such assets are not held in segregation or otherwise regulated under the Commodity Exchange Act, unless such over-the-counter counterparty is registered as a futures commission merchant. These assets are held in either U.S. government securities or short-term time deposits with U.S.-regulated bank affiliates of the over-the-counter counterparties. The remaining approximately 74% to 88% of the Trust’s assets will normally be invested in cash equivalents and short-term investments, such as money market funds and time deposits and held by the clearing broker, the over-the-counter counterparties and by U.S. federally chartered banks. As of September 30, 2011, total cash and cash equivalents and custom time deposits held at banking institutions were $76,013,209 for the Frontier Diversified Series, $0 for the Frontier Dynamic Series, $30,626,179 for the Frontier Long/Short Commodity Series, $38,136,709for the Frontier Masters Series, $137,031,401 for the Balanced Series, $27,343,126 for the Berkeley/Graham/Tiverton Series, $1,922,902 for the Currency Series, $1,231,306 for the Long Only Commodity Series, $2,693,961 for the Managed Futures Index Series, $39,557,999, for the Winton Series, and $25,241,099 for the Winton/Graham Series. As of December 31, 2010, total cash and cash equivalents and custom time deposits held at banking institutions were $81,763,130 for the Frontier Diversified Series, $16,330,890 for the Frontier Dynamic Series, $39,619,945 for the Frontier Long/Short Commodity Series, $21,269,631 for the Frontier Masters Series, $159,675,524 for the Balanced Series, $41,113,225 for the Campbell/Graham/Tiverton Series, $11,653,535 for the Currency Series, $2,924,056 for the Long Only Commodity Series, $3,580,057 for the Managed Futures Index Series, $47,217,883, for the Winton Series, and $41,240,746 for the Winton/Graham Series.

During the second and third quarters of 2011, the Trust experienced redemptions in excess of subscriptions due primarily to seven of the eleven Series being closed to new investments and to the termination of a selling agent relationship. The Managing Owner does not expect any impact on the investment mix of any Series due to the high level of liquidity maintained in the Trust.

Off-Balance Sheet Risk

The term “off-balance sheet risk” refers to an unrecorded potential liability that, even though it does not appear on the balance sheet, may result in future obligation or loss. Each Trading Company trades in futures, forward and swap contracts and is therefore a party to financial instruments with elements of off-balance sheet market and credit risk. In entering into these contracts there exists a market risk that such contracts may be significantly influenced by market conditions, such as interest rate volatility, resulting in such contracts

being less valuable. If the markets should move against all of the futures interests positions held by a Trading Company in respect of any Series at the same time, and if the Trading Advisor(s) of such Trading Company are unable to offset such futures interests positions, such Trading Company could lose all of its assets and the holders of Units of such Series would realize a 100% loss. The Managing Owner seeks to minimize market risk through real-time monitoring of open positions and the level of diversification of each Trading Advisor’s portfolio. It is anticipated that any Trading Advisor’s margin-to-equity ratio will typically not exceed approximately 35% although the actual ratio could be higher or lower from time to time.

In addition to market risk, trading futures, forward and swap contracts entails credit risk which is the risk that a counterparty will not be able to meet its obligations to a Trading Company. The counterparty for futures contracts traded in the U.S. and on most foreign exchanges is the clearinghouse associated with such exchange. In general, clearinghouses are backed by the corporate members of the clearinghouse who are required to share any financial burden resulting from the non-performance by one of their members and, as such, should significantly reduce this credit risk. In cases where the clearinghouse is not backed by the clearing members, like some foreign exchanges, it is normally backed by a consortium of banks or other financial institutions. Some non-U.S. exchanges, in contrast to U.S. exchanges are principals’ markets in which performance is the responsibility only of the individual counterparty with whom the Trading Company has entered into the transaction with and not of the exchange or clearing corporation. In these kinds of markets, there is risk of bankruptcy or other failure or refusal to perform by the counterparty.

In the case of forward contracts traded on the interbank market and swaps, neither is traded on an exchange. The counterparty is generally a single bank or other financial institution, rather than a group of financial institutions; thus, there may be a greater counterparty credit risk. The Managing Owner expects the Trading Advisors to trade only with those counterparties which it believes to be creditworthy. All positions of each Trading Company are valued each day on a mark-to-market basis. There can be no assurance that any clearing member, clearinghouse or other counterparty will be able to meet its obligations to any Trading Company.

The Trust has entered into agreements, which provide for the indemnification of futures clearing brokers, currency trading companies, and commodity trading advisers, among others, against losses, costs, claims and liabilities arising from the performance of their individual obligations under such agreements, except for gross negligence or bad faith. The Trust has had no prior claims or payments pursuant to these agreements. The Trust’s individual maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Trust that have not yet occurred. However, based on experience the Trust expects the risk of loss to be remote.

Tabular Disclosure of Contractual Obligations

The business of the Trust is the speculative trading of commodity interests. The majority of the Trust’s futures and forward positions, which may be categorized as “purchase obligations” under Item 303 of Regulation S-K, are short-term. That is, they are held for less than one year. Because the Trust does not enter into other long-term debt obligations, capital lease obligations, operating lease obligations or other long-term liabilities that would otherwise be reflected on the Trust’s Statement of Financial Condition, a table of contractual obligations has not been presented.

Market Conditions for Nine Months Ended September 30, 2011

Market conditions for 2011 are discussed after the Sector and Major CTA attribution charts included in the Series performance discussion, below.

Market Conditions for Nine Months Ended September 30, 2010

January 2010

Interest Rates

The Federal Open Market Committee (FOMC) decided in January to maintain the target range for the federal funds rate at 0% to 0.25%. The FOMC anticipates that economic conditions, including low rates of resource utilization, subdued inflation trends, and stable inflation expectations, are likely to warrant exceptionally low levels of the federal funds rate for an extended period.

February 2010

Interest Rates

Global markets were jolted by events from the East and the West during February, both of which point towards a tightening of deflationary pressures on a large part of the world’s economy. The ongoing fiscal crisis in Greece dominated the markets until mid month. European Union leaders declared that the European Union (“EU”) member states would do whatever was required to preserve the Euro. Chinese monetary authorities announced mid month a surprise further tightening of monetary policy to prevent overheating and cool asset inflation. For the second time in a month, Chinese banks’ reserve requirements were increased to restrain their loan growth, which has fueled a potential new bubble. Being one of the largest economies in the world, behind the U.S. and Japan, China’s requirement on bank reserves could have a constraining effect on the market. U.S. and European interest rate futures, across the curve, finished slightly up for the month.

76

Currencies

The U.S. dollar index continued to strengthen during February, finishing up 1.1% for the month.

March 2010

Interest Rates

Some degree of optimism about the U.S. economy has resurfaced. Recent U.S. data suggests that economic activity has continued to strengthen and that the labor market is stabilizing. Household spending is expanding at a moderate rate, yet constrained by high unemployment, modest income growth, lower housing wealth, and tight credit. Business spending on equipment and software has risen significantly. However, employers remain reluctant to add to payrolls. To provide support to mortgage lending and housing markets the Federal Reserve has been purchasing $1.25 trillion of agency mortgage-backed securities and about $175 billion of agency debt over the last year. These purchases are coming to an end, as the last transactions were executed in March. The ongoing fiscal crisis in Greece continued to put pressure on Greek government bonds in March. Disagreement among Euro-zone countries over the implementation of the aid program contributed to the sharp yield increase on the 10-year Greek government bond. Some economists say the sharp rise in borrowing costs is contributing to a spiral that could eventually force Greece to a default. U.S. interest rate futures, across the curve, finished down for the month. European interest rate futures finished the month higher.

April 2010

Interest Rates

Recent U.S. data suggests that economic activity has continued to strengthen and that the labor market is improving. Growth in household spending has picked up recently but remains constrained by high unemployment, modest income growth, lower housing wealth, and tight credit. In Europe, the ongoing fiscal crisis in Greece continued to put pressure on the Euro zone. The concern increased that Greece’s debt troubles would spread throughout Europe, possibly putting a dent in the global economic recovery.

May 2010

Interest Rates

U.S. and German interest rate futures, across the curve, finished higher in May. In Europe, there is a concern that the ongoing debt crisis in Greece may spread to Hungary. Government officials in Hungary raised concerns about the nation suffering the type of debt problems that led to a massive bailout for Greece. The potential losses on the Hungarian debt will likely be shouldered by European banks that are already strained due to the Greek debt crisis. The Federal Reserve reestablished U.S. Dollar liquidity swap facilities with Bank of England, the European Central Bank, the Swiss National Bank, Bank of Canada, and the Bank of Japan in May, as a response to the re-emerging strains in short term funding markets in Europe.

Currencies

The U.S. Dollar index continued to climb during May, finishing up 5.8% for the month.

Lumber’s downturn began in late April shortly before the expiration of a federal tax break for U.S. home buyers. That tax break ended April 30 and lumber investors believed that its expiration would slow demand for newly built homes.

June 2010

Interest Rates

U.S. and German interest rate futures, across the curve, finished higher in June. Even if the worst of the recent financial-market turmoil tied to Europe’s sovereign-debt crisis appears to have passed, there are still reasons to be concerned. The International Monetary Fund (“IMF”) said in an update of its World Economic Outlook that downside risks to the global economy had risen sharply and that “the new forecasts hinge on implementation of policies to rebuild confidence and stability, particularly in the euro area.” Since May 2010, the European Central Bank has purchased nearly $76 billion in government debt of Greece and other vulnerable countries. The government-debt purchase program has been controversial in Europe, particularly in Germany, where the practice fuels fears of a loss of central-bank independence and increases in the money supply, which could lead to inflation.

Currencies

In Europe, FTSE index futures fell 6.2%, CAC-40 futures finished lower by 3.1% and DAX index futures finished down 1.1%.

Energy

July 2010

Interest Rates

U.S. interest rate futures, across the curve, continued climbing to finish higher in July. Demand in all areas of the bond market is strong and it seems to be signaling economic fear despite the stock market’s summer rally. Economic data is showing that the one-year-old recovery from the worst recession in decades is losing momentum. The unemployment rate remains painfully high. Since February 2009 the jobless rate has climbed from 8.1% to 9.5% and the private industry has shed two million jobs. Employers still don’t seem confident enough to add new workers. A record 6.7 million Americans have now been out of work for at least six months and, 18 months after the $862 billion stimulus bill passed in 2009, there are still five job seekers for every job opening. In less than two years, federal spending has increased dramatically and the national debt has skyrocketed from $9.3 trillion to $13.3 trillion.

Currencies

The U.S. Dollar index continued to drop in July, down 5.2% for the month. The Euro strengthened against the U.S. Dollar, up 6.7% for the month. The British Pound, the Swiss Franc and the Japanese Yen also strengthened against the U.S Dollar, up 5.0%, 3.5% and 2.3%, respectively, for the month. The Australian and Canadian Dollars also gained against their U.S. counterpart, up 7.6% and 3.3%, respectively.

Stock Indices

Most of the major U.S. and European stock indices finished higher in July. DJIA, the S&P 500 Index and the NASDAQ Composite Index gained 7.1%, 6.9% and 6.9%, respectively, for the month. In Europe, FTSE index futures finished up 9.2%, CAC-40 futures finished up 7.6% and DAX index futures gained 4.4%.

Metals

Agriculturals

Wheat futures surged to sharply higher levels in July, up 37.7% for the month, which would suggests a world in panic over supplies of the grain. Although there has been no significant surge in export demand for U.S. wheat, the worst Russian drought in 130 years could cut into supplies from the world’s third largest exporter. Rough rice futures reversed its downward path, finishing up 9.0% in July. Corn and the soybean complex finished higher in July.

August 2010

Interest Rates

U.S. and European interest rate futures, across the curve, continued climbing to finish higher in August. Recent U.S. data suggests that economic activity has slowed down and that the one-year-old recovery from the worst recession in decades is losing momentum. The unemployment rate remains painfully high and employers still do not seem confident enough to add new workers.

Currencies

The U.S. Dollar index finished higher by 2.0% in August. The Euro and The British Pound weakened against the U.S. Dollar, down 2.9% and 2.2%, respectively, for the month.

The Australian and Canadian Dollars weakened against their U.S. counterpart, down 1.5% and 3.4%, respectively in August.

Stock Indices

September 2010

Interest Rates

Short and mid-term U.S. interest rate futures continued climbing to finish higher in September, while long-term U.S. interest rates finished lower. Recent U.S. data indicates that the pace of the economic recovery has slowed in recent months. Household spending remains constrained by high unemployment, modest income growth, lower housing wealth, and tight credit. In Europe, German interest rate futures, across the curve, finished the month down.

Metals

Most precious metals futures strengthened in September. Gold and silver futures finished up 4.7% and 12.3%, respectively. Platinum, palladium and copper futures also finished up, 8.5%, 13.8% and 8.4%, respectively.

Agriculturals

Rough rice and corn futures continued their climb since July this year, up 10.8% and 12.9%, respectively, in September. Cotton futures climbed as well fueled by increased demand from China and expected poor harvests that will keep the global supply tight, up 18.2% for the month. Sugar futures have also seen dramatic increase in prices during the last few months, up 21.5% for September.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Series are speculative commodity pools. The market sensitive instruments which are held by the Trading Companies in which the Series are invested are acquired for speculative trading purposes, and all or a substantial amount of the Series’ assets are subject to the risk of trading loss. Unlike an operating company, the risk of market sensitive instruments is integral, not incidental, to the Series’ main line of business.

Market movements result in frequent changes in the fair market value of each Trading Company’s open positions and, consequently, in each Series of the Trust’s earnings and cash flow. The Trading Companies’ and consequently the Series’ market risk is influenced by a wide variety of factors, including the level and volatility of exchange rates, interest rates, equity price levels, the market value of financial instruments and contracts, the diversification effects among the open positions and the liquidity of the markets in which trades are made.

Each Trading Company rapidly acquires and liquidates both long and short positions in a wide range of different markets. Consequently, it is not possible to predict how a particular future market scenario will affect performance, and the past performance for any Series is not necessarily indicative of the future results of such Series.

The Trading Companies’ and consequently the Series’ primary market risk exposures as well as the strategies used and to be used by the Trading Advisors for managing such exposures are subject to numerous uncertainties, contingencies and risks, any one of which could cause the actual results of the Trust’s and the Managing Owner’s risk controls to differ materially from the objectives of such strategies. Government interventions, defaults and expropriations, illiquid markets, the emergence of dominant fundamental factors, political upheavals, changes in historical price relationships, an influx of new market participants, increased regulation and many other factors could result in material losses as well as in material changes to the risk exposures and the risk management strategies of the Trading Companies and consequently the Trust. There can be no assurance that the Trading Companies’ current market exposure and/or risk management strategies will not change materially or that any such strategies will be effective in either the short-term or long-term. Investors must be prepared to lose all or substantially all of their investment in a Series.

Quantitative Market Risk

Trading Risk

The Series’ approximate risk exposure in the various market sectors traded by its trading advisors is quantified below in terms of value at risk. Due to the Series’ mark-to-market accounting, any loss in the fair value of the Series’ (through the Trading Companies) open positions is directly reflected in the Series’ earnings, realized or unrealized.

Exchange maintenance margin requirements have been used by the Trust as the measure of its value at risk. Maintenance margin requirements are set by exchanges to equal or exceed the maximum losses reasonably expected to be incurred in the fair value of any given contract in 95% to 99% of any one-day interval. The maintenance margin levels are established by brokers, dealers and exchanges using historical price studies as well as an assessment of current market volatility and economic fundamentals to provide a probabilistic estimate of the maximum expected near-term one-day price fluctuation. Maintenance margin has been used rather than the more generally available initial margin, because initial margin includes a credit risk component that is not relevant to value at risk.

In the case of market sensitive instruments that are not exchange-traded, including currencies and some energy products and metals, the margin requirements for the equivalent futures positions have been used as value at risk. In those cases in which a futures- equivalent margin is not available, dealers’ margins have been used.

In the case of contracts denominated in foreign currencies, the value at risk figures include foreign currency margin amounts converted into U.S. Dollars with an incremental adjustment to reflect the exchange rate risk inherent to the Series, which is valued in U.S. Dollars, in expressing value at risk in a functional currency other than U.S. Dollars.

In quantifying each Series’ value at risk, 100% positive correlation in the different positions held in each market risk category has been assumed. Consequently, the margin requirements applicable to the open contracts have simply been aggregated to determine each trading category’s aggregate value at risk. The diversification effects resulting from the fact that the Series’ positions held through the Trading Companies are rarely, if ever, 100% positively correlated have not been reflected.

Value at Risk by Market Sectors

The following table presents the trading value at risk associated with each Series’ exposure to open positions (as held by the Trading Companies) by market sector as of September 30, 2011 and December 31, 2010. All open position trading risk exposures of the Series have been included in calculating the figures set forth below.

(5) As of December 31, 2010, a portion of the assets of the Currency Series was invested in an Option basket of futures contracts with a notional value of $11,567,063, respectively. Margin information is not available for this contract therefore no value at risk calculations were included in the table for this investment.

Material Limitations on Value at Risk as an Assessment of Market Risk

The face value of the market sector instruments held on behalf of the Series is typically many times the applicable maintenance margin requirement, which generally ranges between approximately 1% and 10% of contract face value, as well as many times the capitalization of the Series. The magnitude of each Series’ open positions creates a risk of ruin not typically found in most other investment vehicles. Because of the size of their positions, certain market conditions, although unusual, but historically recurring from time to time, could cause a Series to incur severe losses over a short period of time. The value at risk table above, as well as the past performance of the Series, gives no indication of this risk of ruin.

Non-Trading Risk

The Series have non-trading market risk on their foreign cash balances not needed for margin. However, these balances, as well as the market risk they represent, are immaterial. The Series also have non-trading market risk as a result of investing a portion of their available assets in U.S. government securities which include any security issued or guaranteed as to principal or interest by the U.S., or by a person controlled by or supervised by and acting as an instrumentality of the government of the U.S. pursuant to authority granted by Congress of the U.S. or any certificate of deposit for any of the foregoing, including U.S. treasury bonds, U.S. treasury bills and issues of agencies of the U.S. government, and certain cash items such as money market funds, certificates of deposit (under nine months) and time deposits. The market risk represented by these investments is also immaterial.

Qualitative Market Risk

The following are the primary trading risk exposures of the Series of the Trust as of September 30, 2011, by market sector.

105

Interest rates

Interest rate risk is one of the principal market exposures of each Series. Interest rate movements directly affect the price of interest rate futures positions held and indirectly the value of a Trading Company’s stock index and currency positions. Interest rate movements in one country as well as relative interest rate movements between countries materially impact profitability. The primary interest rate exposure is to interest rate fluctuations in the U.S.and the other G-7 countries. However, the Trading Companies also may take futures positions on the government debt of smaller nations. The Managing Owner anticipates that G-7 interest rates will remain the primary market exposure of each Trading Company and accordingly of each Series for the foreseeable future. The changes in interest rates which are expected to have the most effect on the Series are changes in long-term, as opposed to short-term rates. Most of the speculative positions to be held by the Trading Companies will be in medium- to long-term instruments. Consequently, even a material change in short-term rates is expected to have little effect on the Series if the medium- to long-term rates remain steady. Aggregate interest income from all sources, including assets held at clearing brokers, up to 2% (annualized) is paid to the Managing Owner by the Balanced Series (Class 1 and Class 2 only), Winton Series, Berkeley/Graham/Tiverton Series, Currency Series and Winton/Graham Series. For the Frontier Diversified Series, Frontier Dynamic Series, Frontier Long/Short Commodity Series, Frontier Masters Series, Balanced Series (Class 1a and Class 2a only), Long Only Commodity Series and Managed Futures Index Series, 20% of the total interest allocated to each Series is paid to the Managing Owner. In addition, if interest rates fall below 0.75%, the Managing Owner is paid the difference between the Trust’s annualized interest income that is allocated to each of such Series and 0.75%. Interest income above what is paid to the Managing Owner is retained by the Series.

Currencies

Exchange rate risk is a significant market exposure of each Series of the Trust in general and the Currency Series in particular. For each Series of the Trust in general, and the Currency Series in particular, currency exposure is to exchange rate fluctuations, primarily fluctuations that disrupt the historical pricing relationships between different currencies and currency pairs. These fluctuations are influenced by interest rate changes as well as political and general economic conditions. The Trading Advisors on behalf of a Series trade in a large number of currencies, including cross-rates, which are positions between two currencies other than the U.S. Dollar. The Managing Owner does not anticipate that the risk profile of the Series’ currency sector will change significantly in the future.

Stock Indices

For each Series (other than the Currency Series), its primary equity exposure is equity price risk in the G-7 countries as well as other smaller jurisdictions. Each Series of the Trust (other than the Currency Series) is primarily exposed to the risk of adverse price trends or static markets in the major U.S., European and Japanese indices.

Metals

For each Series (other than the Currency Series), its metals market exposure is fluctuations in the price of both precious metals, including gold and silver, as well as base metals including aluminum, copper, nickel and zinc. Some metals, such as gold, are used as surrogate stores of value, in place of hard currency, and thus have an associated currency or interest rate risk associated with them relative to their price in a specific currency. Other metals, such as silver, platinum, copper and steel, have substantial industrial applications, and may be subject to forces affecting industrial production and demand.

Agriculturals/Softs

Each Series (other than the Currency Series) may also invest in raw commodities and may thus have exposure to agricultural price movements, which are often directly affected by severe or unexpected weather conditions or by political events in countries that comprise significant sources of commodity supply.

Energy

For each Series (other than the Currency Series), its primary energy market exposure is in oil, gas and other energy product price movements, often resulting from political developments and ongoing conflicts in the Middle East. Oil and gas prices can be volatile and substantial profits and losses have been and are expected to continue to be experienced in this market.

Other Trading Risks

As a result of leverage, small changes in the price of a Trading Company’s positions may result in substantial losses for a Series. Futures, forwards and options are typically traded on margin. This means that a small amount of capital can be used to invest in contracts of much greater total value. The resulting leverage means that a relatively small change in the market price of a contract can produce a substantial loss. Like other leveraged investments, any purchase or sale of a contract may result in losses in excess of the amount invested in that contract. The Trading Companies may lose more than their initial margin deposits on a trade.

The Trading Companies’ trading is subject to execution risks. Market conditions may make it impossible for the Trading Advisors to execute a buy or sell order at the desired price, or to close out an open position. Daily price fluctuation limits are established by the

106

exchanges and approved by the CFTC. When the market price of a contract reaches its daily price fluctuation limit, no trades can be executed at prices outside the limit. The holder of a contract may therefore be locked into an adverse price movement for several days or more and lose considerably more than the initial margin put up to establish the position. Thinly traded or illiquid markets also can make it difficult or impossible to execute trades. The Trading Advisor’s positions are subject to speculative limits. The CFTC and domestic exchanges have established speculative position limits on the maximum futures position which any person, or group of persons acting in concert, may hold or control in particular futures contracts or options on futures contracts traded on U.S. commodity exchanges. Under current regulations, other accounts of the Trading Advisors are combined with the positions held by them on behalf of the applicable Trading Company for position limit purposes. This trading could preclude additional trading in these commodities by the Trading Advisors for the accounts of the Series.

Systematic strategies do not consider fundamental types of data and do not have the benefit of discretionary decision making. The assets of the Series are allocated to Trading Advisors that rely on technical, systematic strategies that do not take into account factors external to the market itself (although certain of these strategies may have minor discretionary elements incorporated into their systematic strategy). The widespread use of technical trading systems frequently results in numerous trading advisors attempting to execute similar trades at or about the same time, altering trading patterns and affecting market liquidity. Furthermore, the profit potential of trend-following systems may be diminished by the changing character of the markets, which may make historical price data (on which technical programs are based) only marginally relevant to future market patterns. Systematic strategies are developed on the basis of a statistical analysis of market prices. Consequently, any factor external to the market itself that dominates prices that a discretionary decision maker may take into account may cause major losses for a systematic strategy. For example, a pending political or economic event may be very likely to cause a major price movement, but a systematic strategy may continue to maintain positions indicated by its trading method that might incur major losses if the event proved to be adverse.

However, because certain of the Trading Advisors’ strategies involve some discretionary aspects in addition to their technical factors, certain of the Trading Advisors may occasionally use discretion in investing the assets of a Trading Company. For example, the Trading Advisors often use discretion in selecting contracts and markets to be followed. In exercising such discretion, such Trading Advisor may take positions opposite to those recommended by the Trading Advisor’s trading system or signals. Discretionary decision making may also result in a Trading Advisor failing to capitalize on certain price trends or making unprofitable trades in a situation where another trader relying solely on a systematic approach might not have done so. Furthermore, such use of discretion may not enable the relevant Series of the Trust to avoid losses, and in fact, such use of discretion may cause such Series to forego profits which it may have otherwise earned had such discretion not been used.

Qualitative Disclosures Regarding Means of Managing Risk Exposure

The means by which the Managing Owner attempts to manage the risk of the Trust’s open positions is essentially the same in all market categories traded. The Managing Owner applies risk management policies to trading which generally are designed to limit the total exposure of assets under management. In addition, the Managing Owner follows diversification guidelines which are often formulated in terms of the balanced volatility between markets and correlated groups.

Evaluation of disclosure controls and procedures

Under the supervision and with the participation of the management of the Managing Owner, including its Chief Executive Officer and Chief Accounting Officer, the Trust evaluated the effectiveness of the design and operation of the disclosure controls and procedures (as defined in Rule 13(a)-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), for the Trust and each Series as of September 30, 2011 (the “Evaluation Date”). Any control system, no matter how well designed and operated, can provide only reasonable (not absolute) assurance that its objectives will be met. Furthermore, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, have been detected. Based upon our evaluation, the Chief Executive Officer and Chief Accounting Officer of the Managing Owner concluded that, as of the Evaluation Date, the disclosure controls and procedures for the Trust and each Series were effective to provide reasonable assurance that they are timely alerted to the material information relating to the Trust and each Series required to be included in the Trust’s periodic SEC filings.

Changes in Internal Control Over Financial Reporting

There were no changes in the Trust’s internal control over financial reporting during the nine months ended September 30, 2011, that have materially affected, or are reasonably likely to materially affect, the Trust’s internal control over financial reporting.

Scope of Exhibit 31 Certifications

The certifications of the Chief Executive Officer and the Chief Accounting Officer of the Managing Owner included as Exhibits 31.1 and 31.2, respectively, to this Form 10-Q apply not only to the Trust as a whole but also to each Series individually.

Significant Accounting Policies [Abstract]

Significant Accounting Policies

2. Significant Accounting Policies

The following are the significant accounting policies of the Trust.

Basis of Presentation—The Financial Accounting Standards Board's ("FASB") Accounting Standards Codification ("ASC") is now FASB's officially recognized source of authoritative U.S. generally accepted accounting principles ("GAAP") applicable to all public and non-public non-governmental entities, superseding FASB, American Institute of Certified Public Accountants, Emerging Issues Task Force and related literature. Rules and interpretive releases of the SEC under the authority of federal securities laws are also sources of authoritative GAAP for Securities and Exchange Commission ("SEC") registrants. All other accounting literature is considered non-authoritative. Existing GAAP prior to the effective date of the ASC was not altered in compilation of the ASC. Citing particular content in the ASC involves specifying the unique numeric path to the content through the Topic, Subtopic, Section and Paragraph structure.

These financial statements should be read in conjunction with the audited financial statements and notes thereto included in our 2010 Annual Report on Form 10-K as filed with the SEC.

Consolidation—The Series, through investing in the Trading Companies, authorize certain Trading Advisors to place trades and manage assets at pre-determined investment levels. The Trading Companies were organized by the Managing Owner for the purpose of investing in commodities interests and derivative instruments, and have no operating income or expenses, except for trading income and expenses, all of which is allocated to the Series. Trading Companies in which a Series has a controlling and majority equity interest are consolidated by such Series. Investments in Trading Companies in which a Series does not have a controlling and majority interest are accounted for under the equity method, which approximates fair value. The equity interest held by Series of the Trust is shown as investments in unconsolidated trading companies in the statements of financial condition. The income or loss attributable thereto in proportion of investment level is shown in the statements of operations as equity in earnings/(loss) from unconsolidated trading companies.

Investments in Trading Companies in which a Series does not have a controlling or majority interest are carried in the statements of financial condition of such Series using the equity method of accounting, which approximates fair value. Fair value represents the proportionate share of the Series interest in the NAV in a Trading Company.

The Berkeley/Graham/Tiverton Series has an investment in the Berkeley Quantitative Colorado Fund, LLC. The Berkeley Quantitative Colorado Fund, LLC is not consolidated into the financial statements of the Berkeley/Graham/Tiverton Series because the Trust has no control or transparency over the operations of the Trading Company. This investment is on the statements of financial condition as investment in Berkeley Quantitative Colorado Fund, LLC and any changes in fair value shown are shown on the statements of operations as net unrealized gain/(loss) on investment in Berkeley Quantitative Colorado Fund, LLC.

Use of Estimates—The preparation of financial statements in conformity with GAAP may require the Managing Owner to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. The valuation of swap contracts requires significant estimates as well as the valuation of certain other investments. Please refer to Note 3 for discussion of valuation methodology.

Cash and Cash Equivalents—Cash and cash equivalents include cash and overnight investments in interest-bearing demand deposits held at banks with maturities of three months or less.

Interest Income—Aggregate interest income from all sources, including assets held at Futures Commission Merchants ("FCM"), up to two percentage points of the aggregate percentage yield (annualized) is paid to the Managing Owner by the Balanced Series (Class 1 and Class 2 only), Berkeley/Graham/Tiverton Series, Currency Series, Winton Series and Winton/Graham Series. For the Frontier Diversified Series, Frontier Dynamic Series, Frontier Long/Short Commodity Series, Frontier Masters Series, Balanced Series (Class 1a, Class 2a and Class 3a only), Long Only Commodity Series and Managed Futures Index Series, 20% of the total interest allocated to each Series is paid to the Managing Owner. All interest not paid to the Managing Owner is interest income to the Series.

U.S. Treasury Securities, custom time deposits and certain demand deposits are pooled for purposes of maximizing returns on these assets to investors of all Series. Interest income from pooled cash management assets is recognized on the accrual basis and allocated daily to each Series based upon its daily proportion of ownership of the pool. Interest income from demand deposits of the Series is allocated to the respective Series in proportion to their daily NAV.

U.S. Treasury Securities—U.S. Treasury Securities are allocated to all Series based on each Series' percentage ownership in the pooled cash management assets as of the reporting date. They are reported at fair value as Level 1 inputs under ASC 820, Fair Value Measurements and Disclosures ("ASC 820"). The Trust values U.S. Treasury Securities at fair value and records the daily change in value in the statements of operations as net unrealized gain/(loss) on U.S. Treasury securities. Accrued interest is reported on the statements of financial condition as interest receivable.

Custom Time Deposits—Custom time deposits are structured deposit agreements with U.S. Bank National Association that earn a guaranteed fixed interest rate between 2.17% and 3.75% , mature nine months from the deposit date and are subject to automatic six-month rollovers through October 2013. Custom time deposits were purchased on September 15, 2009, October 21, 2008 and October 30, 2008. Interest is paid monthly or at least every nine months. Unscheduled withdrawals will be subject to certain penalties and other costs of up to 1.0% of the amount deposited if withdrawn within the first nine months from the deposit date. The withdrawal fee is set at 0.225% for the period from nine months to one year subsequent to the deposit date and decreases by .05% increments for each year thereafter through the maturity date. Custom time deposits are allocated to each Series based on their percentage ownership in the pooled cash management assets as of the reporting date. The Trust values the custom time deposits at face value plus accrued interest as it is considered a deposit account under paragraph 7.50 of the Investment Company Audit Guide, and accordingly, this deposit is not subject to ASC 820.

Credit Default Swaps—The Trust invests in credit default swaps for the purpose of mitigating part of the risk of concentration of deposits with U.S. Bank National Association to other major financial institutions. See Note 4. Credit Default Swaps are allocated to each Series based on their percentage ownership in the pooled cash management assets as of the reporting date. Credit Default Swaps are reported at fair value based upon daily valuations provided by a third party pricing service. The Series record the daily change in fair value in the statements of operations as net unrealized gain/(loss) on swap contracts.

Receivable From Futures Commission Merchants—The Trust deposits assets with a FCM subject to CFTC regulations and various exchange and broker requirements. Margin requirements are satisfied by the deposit of cash with such FCM. The Trust earns interest income on its assets deposited with the FCM.

Investment Transactions—Futures, options on futures, forward and swap contracts are recorded on a trade date basis and realized gains or losses are recognized when contracts are settled. Unrealized gains or losses on open contracts (the difference between contract trade price and market price) are reported in the statements of financial condition as a net unrealized gain or loss, as there exists a right of offset of unrealized gains or losses in accordance with FASB ASC 210, Balance Sheet ("ASC 210").

Any change in net unrealized gain or loss from the preceding period is reported in the statements of operations. Fair value of exchange-traded contracts is based upon exchange settlement prices. Fair value of non-exchange-traded contracts is based on third party quoted dealer values on the interbank market. For U.S. Treasury securities, interest is recognized in the period earned and the instruments are marked-to-market daily based on third party information. Custom time deposits are valued at face value plus accrued interest and the interest income is recognized in the period earned. Transaction costs are recognized as incurred and reflected separately in the statements of operations.

Allocation of Earnings—Each Series of the Trust maintains three or six classes of Units—Class 1, Class 2, Class 3, Class 1a, Class 2a and Class 3a). All classes have identical voting, dividend, liquidation and other rights and the same terms and conditions, except that fees charged to a Class or Series differ as described below. Revenues, expenses (other than expenses attributable to a specific class), and realized and unrealized trading gains and losses of each Series are allocated daily to Class 1, Class 1a, Class 2, Class 2a, Class 3 and Class 3a Units based on each Class' respective owners' capital balances.

Each Series allocates funds to an affiliated Trading Company, or Companies, of the Trust. Each Trading Company allocates all of its daily trading gains or losses to the Series in proportion to each Series' ownership interest in the Trading Company, adjusted on a daily basis. As of September 30, 2011, the value of all open contracts and cash held at clearing brokers is similarly allocated to the Series in proportion to each Series' funds allocated to the Trading Company, or Companies.

Inter-Series Receivables/Payables—The Balanced Series, for the purposes of diversification of investments and trading advisors through the other Series' access to trading companies in which the Balanced Series did not have a direct interest, advanced funds to the Currency Series and the Frontier Dynamic Series. The amount of the funds advanced by the Balanced Series to each of the Currency Series and the Frontier Dynamic Series participated on a pari passu basis with Class 2 Units of such investee Series. The Balanced Series and investee Series reflected the changes in values of these investments as "net change in inter-series receivables/payables" in the statements of operations. The Balanced Series was subject to the same allocations of income and fees as the Limited Owners of such Series. As a result of fees charged by the investee Series, fees were not charged by the Balanced Series on the capital allocated to advances in affiliated Series. The Managing Owner monitored such allocations so that aggregate fees of the investee Series on the Balanced Series advances did not exceed the allowable fees of the Balanced Series as provided in the Trust's Prospectus. Interest was not credited to the Balanced Series on the capital allocated to its inter-series advances to avoid the duplication of interest charged or received. These investments were liquidated during the third quarter of 2011.

Payments by the Managing Owner — The Trust may make discretionary payments to a Series related to a variety of factors, including investment losses to reimburse the effect of a loss on a portfolio investment which has been caused by a situation outside the Trust's, or it's affiliates', direct control. Such payments will be made on a discretionary basis and will be disclosed in the statement of operations as a net increase from payments by managing owner. These payments are in accordance with the Trust agreement on a discretionary basis as determined by the Managing Owner.

Investments and Swaps—The Trust records investment transactions on a trade date basis and all investments are recorded at fair value in its financial statements, with changes in fair value reported as a component of realized and unrealized gains/(losses) on investments in the statements of operations. Certain Series of the Trust strategically invest a portion or all of their assets in total return Swaps, selected at the discretion of the Managing Owner. Swaps are privately negotiated contracts designed to provide investment returns linked to those produced by one or more underlying investment products or indices. In a typical Swap, two parties agree to exchange the returns (or differentials in rates of return) earned or realized on one or more particular predetermined investments or instruments. The gross returns to be exchanged or "swapped" between the parties are calculated with respect to a "notional amount" (i.e., the amount of value of the underlying asset used in computing the particular interest rate, return, or other amount to be exchanged) in a particular investment, or in a "basket" of securities. The valuation of swap contracts requires significant estimates. Swap contracts utilizing Level 2 inputs are reported at fair value based on daily reports from the swap counterparty that are corroborated against independent valuation/rate of return information published and available on a daily recurring frequency. Other Swap Contracts are reported utilizing Level 3 Inputs. Swap Contracts are reported at fair value based upon a weekly indicative value that is calculated by management using bid/ask prices from the counterparty. This fair value is corroborated by a daily range of valuations provided by a third party pricing service. The third party pricing service utilizes a Black Scholes pricing model with input adjustments factoring in volatility and liquidity of the instruments. All valuation processes are monitored by the valuation committee of the Managing Owner.

Income Taxes—The Trust applies the provisions of ASC 740 Income Taxes ("ASC 740"), which provides guidance for how uncertain tax positions should be recognized, measured, presented and disclosed in the financial statements. This interpretation also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods and disclosure. ASC 740 requires the evaluation of tax positions taken or expected to be taken in the course of preparing the Trust's financial statements to determine whether the tax positions are "more-likely-than-not" of being sustained by the applicable tax authority. Tax positions with respect to tax at the Trust's level not deemed to meet the "more-likely-than-not" threshold would be recorded as a tax benefit or expense in the current year. The Managing Owner has concluded there is no tax expense, interest or penalties to be recorded by the Trust for the year ended December 31, 2010. The 2008 through 2010 tax years generally remain subject to examination by U.S. federal and most state tax authorities.

In the opinion of the Managing Owner, (i) the Trust is treated as a partnership for Federal income tax purposes and, assuming that at least 90% of the gross income of the Trust constitutes "qualifying income" within the meaning of Section 7704(d) of the Code, the Trust is not a publicly traded partnership treated as a corporation, and (ii) the discussion set forth in the Prospectus under the heading "Federal Income Tax Consequences" correctly summarizes the material Federal income tax consequences as of the date of the Prospectus to potential U.S. Limited Owners of the purchase, ownership and disposition of Units of the Trust.

Fees and Expenses—All management fees, incentive fees, service fees and trading fees of the Trust are paid to the Managing Owner. It is the responsibility of the Managing Owner to pay all Trading Advisor management and incentive fees, Selling Agent Service fees and all other operating expenses and continuing offering costs of the Trust.

Service Fees—The Trust maintains each Series of Units in three or six sub-classes—Class 1, Class 1a, Class 2, Class 2a, Class 3, and Class 3a. Investors who have purchased Class 1 or Class 1a Units of any Series are charged a service fee of up to three percent (3.0%) annually of the NAV of each Unit purchased, for the benefit of selling agents selling such Class 1 or Class 1a Units. The initial service fee, which is amortized monthly at an annual rate of up to three percent (3.0%) of the average daily NAV of Class 1 or Class 1a of such Series, is prepaid to the Managing Owner by each Series, and paid to the selling agents by the Managing Owner in the month following sale; provided, however, that investors who redeem all or a portion of their Class 1 or Class 1a Units of any Series during the first twelve (12) months following the effective date of their purchase are subject to a redemption fee of up to three percent (3.0%) of the NAV at which such investor redeemed to reimburse the Managing Owner for the then-unamortized balance of the prepaid initial service fee. With respect to Class 2 and Class 2a Units of any Series, the Managing Owner pays an ongoing service fee to Selling Agents of up to one half percent (0.5%) annually of the NAV of each Class 2 or Class 2a Unit (of which 0.25% will be charged to Limited Owners holding Class 2 Units of the Frontier Diversified Series, Frontier Dynamic Series and Frontier Masters Series or Class 2a Units of the Frontier Long/Short Commodity Series) sold until such Class 2 or Class 2a Units which are subject to the fee limitation are reclassified as Class 3 or Class 3a Units of the applicable Series for administrative purposes. The Managing Owner may also pay Selling Agents certain additional fees and expenses for administrative and other services rendered and expenses incurred by such Selling Agents.

These service fees are part of the offering costs of the Trust, which include registration and filing fees, legal and blue sky expenses, accounting and audit, printing, marketing support and other offering costs which are born by the Managing Owner. With respect to the service fees, the initial service fee (for the first 12 months) relating to a purchase of Class 1 and Class 1a Units by an investor is prepaid by the Managing Owner to the relevant selling agent in the month following such purchase and is reimbursed for such payment by the Series monthly in arrears in an amount based upon a corresponding percentage of NAV, calculated daily. Consequently, the Managing Owner bears the risk of the downside and enjoys the benefit of the upside potential of any difference between the amount of the initial service fee prepaid by it and the amount of the reimbursement thereof, which may result from variations in NAV over the following 12 months.

Pending Owner Additions—Funds received for new subscriptions and for additions to existing owner interests are recorded as capital additions at the NAV per unit of the second business day following receipt.

Recently Adopted Accounting Pronouncements—In January 2010, FASB issued Accounting Standards update No. 2010-06 ("ASU 2010-06") for improving disclosure about fair value measurements. ASU 2010-06 adds new disclosure requirements about transfers into and out of Levels 1 and 2 and separate disclosures about purchases, sales, issuances and settlements in the reconciliation for fair value measurements using significant unobservable inputs (Level 3). It also clarifies existing disclosure requirements relating to the levels of disaggregation for fair value measurement and inputs and valuation techniques used to measure fair value. The amended guidance is effective for financial statements for fiscal years and interim periods beginning after December 15, 2009 except for disclosures about purchases, sales, issuances and settlements in the roll forward of activity in Level 3 fair value measurements, which are effective for fiscal years beginning after December 15, 2010 and for interim periods within those fiscal years. As this update is disclosure related, adoption of ASU 2010-06 on January 1, 2011 did not have a material impact on the Trust's statement of financial condition, results of operations or cash flows.

Recently Issued Accounting Pronouncements—In May 2011, the FASB issued ASU No. 2011-04 which provides guidance pertaining to fair value measurement that included a common definition of fair value and information to assist reporting entities to measure and disclose fair value with regards to U.S. GAAP and International Financial Reporting Standards ("IFRS") convergence issues. This guidance becomes effective for interim and annual periods beginning on or after December 15, 2011, with early adoption prohibited. We are currently evaluating the impact that this accounting guidance may have on the Trust's statement of financial condition, results of operations or cash flows.

Reclassification—Certain amounts in the 2010 financial statements have been reclassified to conform to the 2011 presentation. None of the reclassifications had an impact of the NAV of any of the Series.

Subsequent Events —The Trust follows the provisions of FASB ASC 855, Subsequent Events , which establishes general standards of accounting for and disclosure of events that occur after the balance sheet date but before financial statements are issued. Refer to Note 11.

Investments In Unconsolidated Trading Companies [Abstract]

Investments In Unconsolidated Trading Companies

5. Investments in Unconsolidated Trading Companies

Investments in unconsolidated trading companies represent cash and open trade equity invested in the Trading Companies by each Series and cumulative trading profits or losses allocated to each Series by the Trading Companies. Trading Companies allocate trading profits or losses on the basis of the proportion of each Series' capital allocated for trading to each respective Trading Company, which bears no relationship to the amount of cash invested by a Series in the Trading Company. The Trading Companies are valued using the equity method of accounting, which approximates fair value.

The following table summarizes the Balanced Series, Winton Series, Currency Series, Berkeley/Graham/Tiverton Series, Winton/Graham Series, Frontier Long/Short Commodity Series, Managed Futures Index Series, Frontier Diversified Series, and Frontier Masters Series investments in unconsolidated Trading Companies as of September 30, 2011 and December 31, 2010.

The Managing Owner contributes funds to the Trust in order to have a 1% interest in the aggregate capital, profits and losses of all Series and in return will receive units designated as general units in the Series in which the Managing Owner invests such funds. The general units may only be purchased by the Managing Owner and may be subject to no advisory fees or advisory fees at reduced rates. Otherwise, the general units hold the same rights as the limited units. The Managing Owner is required to maintain at least a 1% interest ("Minimum Purchase Commitment") in the aggregate capital, profits and losses of all Series so long as it is acting as the Managing Owner of the Trust. Such contribution was made by the Managing Owner before trading commenced for the Trust and will be maintained throughout the existence of the Trust, and the Managing Owner will make such purchases as are necessary to effect this requirement. Additionally, the Managing Owner agreed with certain regulatory bodies to maintain a 1% interest specifically in the Balanced Series Class 1 a Units and Balanced Series Class 2a Units, aggregated, and each of the Long Only Commodity Series, Frontier Long/Short Commodity Series, Managed Futures Index Series, Frontier Diversified Series, Frontier Dynamic Series and Frontier Masters Series. The 1% interest in these specific Series is included in computing the Minimum Purchase Commitment in aggregate capital. In addition to the General Units the Managing Owner receives in respect of its Minimum Purchase Commitment, the Managing Owner may purchase Limited Units in any Series as a Limited Owner. Principals of the Managing Owner or affiliates are allowed to own beneficial interests in the Trust, as well. All Units purchased by the Managing Owner are held for investment purposes only and not for resale. The Managing Owner may make purchases or redemptions at any time on the same terms as any Limited Owner. The Trust has and will continue to have certain relationships with the Managing Owner and its affiliates.

The Balanced Series had advanced funds to the Currency Series, Frontier Diversified Series, Frontier Dynamic Series and Frontier Masters Series for the purpose of investing in the respective Trading Company for such Series on behalf of the Balanced Series. All of these investments have been liquidated as of September 30, 2011.

On July 18, 2011, the Balanced Series reduced its inter-series advance to the Dynamic Series in exchange for ownership in a total return swap contract in the amount of $27,379,284 which approximated fair value in accordance with the Trust's valuation policies at the date of transfer.

The following table summarizes the Balanced Series advances to and reductions from the Currency Series, Frontier Diversified Series, Frontier Dynamic Series and Frontier Masters Series of the Trust for the nine months ended September 30, 2011 and the year ended December 31, 2010.

(1) Balanced Series Inter-series receivables are corresponding Inter-series payables on the Statements of Financial Condition for the investee Series.

Expenses

Management Fees—Each Series of Units pays to the Managing Owner a monthly management fee equal to a certain percentage of such Series' assets attributable to such Series (including notional assets), calculated on a daily basis. The annual rate of the management fee is 0.5% for the Balanced Series, 2.0% for the Winton Series, Currency Series, Long Only Commodity Series, Frontier Long/Short Commodity Series Class 1 a and Class 2a, Managed Futures Index Series, Frontier Diversified Series, Frontier Dynamic Series and Frontier Masters Series, 2.5% for the Winton/Graham Series and Berkeley/Graham/Tiverton Series, and 3.5% for the Frontier Long/Short Commodity Series Class 1 and Class 2. The Managing Owner may pay all or a portion of such management fees to the Trading Advisor(s) for such Series.

Trading Fees—In connection with each Series' trading activities, the Frontier Long/Short Commodity Series (Classes 1, 2 and 3), Balanced Series, Currency Series, Berkeley/Graham/Tiverton Series, Long/Only Commodity Series, Managed Futures Index Series, Winton Series and Winton/Graham Series pays to the Managing Owner a trading fee, or FCM Fee, up to 0.75% of such Series' NAV, calculated daily. The Frontier Diversified Series, Frontier Dynamic Series, Frontier Long/Short Commodity Series (Classes 1a and 2a) and Frontier Masters Series pays to the Managing Owner a trading fee, or FCM Fee, up to 2.25% and a custodial/due diligence fee of 0.12% of such Series' NAV, calculated daily.

Incentive Fees—Some Series pay to the Managing Owner an incentive fee of a certain percentage of new net trading profits generated by such Series, monthly or quarterly. Because the Balanced Series, Winton/Graham Series, Berkeley/Graham/Tiverton Series, Currency Series and Frontier Long/Short Commodity Series may each employ multiple Trading Advisors, these Series will pay the

Managing Owner a monthly incentive fee calculated on a Trading Advisor by Trading Advisor basis. It is therefore possible that in any given period the Balanced Series or the Frontier Long/Short Commodity Series may pay incentive fees to the Managing Owner for one or more Trading Advisors while each of these Series as a whole experiences losses. The incentive fee is 25% for the Balanced Series and the Frontier Diversified Series and 20% for the Winton Series, Currency Series, Winton/Graham Series, Berkeley/Graham/Tiverton Series, Frontier Long/Short Commodity Series, Frontier Dynamic Series and Frontier Masters Series. There is no incentive fee for the Long Only Commodity Series or the Managed Futures Index Series. The Managing Owner may pay all or a portion of such incentive fees to the Trading Advisor(s) for such Series.

Service Fees—In addition, with respect to Class 1 and Class 1a Units of each Series, as applicable, the Series pays monthly or quarterly to the Managing Owner a service fee at an annualized rate, as described in more detail above, which the Managing Owner pays to selling agents of the Trust.

The following table summarizes fees earned by the Managing Owner for the three months ended September 30, 2011 and 2010.

With respect to the service fees, the initial service fee (for the first 12 months) relating to a purchase of Units by an investor is prepaid by the Managing Owner to the relevant selling agent in the month following such purchase and is reimbursed therefore by the Series monthly in arrears in an amount based upon a corresponding percentage of NAV, calculated daily. Consequently, the Managing Owner bears the risk and enjoys the benefit of the upside potential of any difference between the amount of the initial service fee prepaid by it and the amount of the reimbursement thereof, which may result from variations in NAV over the following 12 months. For the nine months ended September 30, 2011, amounts received or receivable from the Managing Owner for the difference in monthly service fees from the prepaid initial service fees were $2,752 for the Frontier Dynamic Series, $17 for the Long/Only Commodity Series and $9 for the Managed Futures Index Series. For the nine months ended September 30, 2011, amounts paid or owing the Managing Owner for the difference in monthly service fees from prepaid initial service fees were $27,761 for the Balanced Series, $17,533 for the Frontier Long/Short Commodity Series, $22,103 for the Frontier Diversified Series, $530 for the Currency Series, $5,509 for the Berkeley/Graham/Tiverton Series, $3,742 for the Winton/Graham Series, $7,838 for the Winton Series and $11,973 for the Frontier Masters Series.

Aggregate interest income from all sources, including assets held at clearing brokers, up to 2% (annualized) is paid to the Managing Owner by the Balanced Series (Class 1 and Class 2 only), Winton Series, Berkeley/Graham/Tiverton Series, Currency Series and Winton/Graham Series. For the Frontier Diversified Series, Frontier Dynamic Series, Frontier Long/Short Commodity Series, Frontier Masters Series, Balanced Series (Class 1a and Class 2a only), Long Only Commodity Series and Managed Futures Index Series 20% of the total interest allocated to each Series is paid to the Managing Owner. During the nine months ended September 30, 2011, and 2010 the Trust paid $7,197,876 and $7,573,585, respectively, of such interest income to the Managing Owner. Such expenses are not included in the statements of operations of the Series.

The Managing Owner pays to The Bornhoft Group Corporation, an affiliate of the Trust, a monthly fee of 0.25% (annualized) of the NAV of the Trust, for services in connection with the daily valuation of each Series and Class. The amount paid under this agreement was $429,634 and $514,050, respectively for the three months ended September 30, 2011 and 2010 and $1,483,875 and $1,472,121, respectively for the nine months ended September 30, 2011 and 2010.

Solon Capital, LLC, an affiliate of the Trust, provides product development and marketing services. For these services, the Managing Owner paid Solon Capital, LLC, $773,341 and $925,290, respectively, for the three months ended September 30, 2011 and 2010 and $2,670,975 and $2,649,818, respectively, for the nine months ended September 30, 2011 and 2010.

Swaps [Abstract]

Swaps

4. Swaps

In addition to authorizing Trading Advisors to manage pre-determined investment levels of futures and forward contracts, certain Series of the Trust will strategically invest a portion or all of their assets in total return Swaps, selected at the direction of the Managing Owner. Total return Swaps are privately negotiated contracts designed to provide investment returns linked to those produced by one or more investment products or indices. In a typical total return Swap, two parties agree to exchange the returns (or differentials in rates of return) earned or realized on one or more particular predetermined investments or instruments. The gross returns to be exchanged or "swapped" between the parties are calculated with respect to a "notional amount" (i.e., the amount or value of the underlying asset used in computing the particular interest rate, return, or other amount to be exchanged) in a particular investment, or in a "basket" of securities.

Each Series invests in Credit Default Swaps ("CDS") with highly-rated counterparties as part of its portfolio. CDSs are over-the-counter investment instruments designed to mitigate counterparty risk and generally pay upon the happening of a credit default of a counterparty. The CDS are allocated to each Series based on their percentage ownership in the pooled cash management assets at U.S. Bank National Association as of the reporting date. Approximately 23% of the Trust's U.S. Bank National Association exposure is risk-hedged in this manner with BNP Paribas through March 20, 2012, and 15% with Societe Generale expiring from December 20, 2011 through March 20, 2012.

Each Series' investment in Swaps will likely differ substantially over time due to cash flows, portfolio management decisions and market movements. For the Balanced Series, Currency Series, and Frontier Diversified Series, the Swaps serve to diversify the investment holdings of each Series and to provide access to programs and advisors that would not be otherwise available to the Series, and are not used for hedging purposes.

The Managing Owner follows a procedure in selecting well-established financial institutions which the Managing Owner, in its sole discretion, considers to be reputable, reliable, financially responsible and well established to act as swap counterparties. The procedure includes due diligence review of documentation on all new and existing financial institution counterparties prior to initiation of the relationship, and quarterly ongoing review during the relationship, to ensure that counterparties meet the Managing Owner's minimum credit requirements, the counterparty average rating being no less than an investment grade rating as defined by the rating agencies. As of September 30, 2011, approximately 5.0% of the Trust's assets were deposited with over-the-counter counterparties in order to initiate and maintain Swaps.

The Balanced Series, Currency Series and Frontier Diversified Series strategically invest assets in one or more Swaps linked to certain underlying investments or indices at the direction of the Managing Owner. The Trading Company in which the assets of these Series will be invested will not own any of the investments or indices referenced by any Swap entered into by these Series. In addition, neither the swap counterparty to the Trading Company of these Series nor any advisor referenced by any such Swap is a Trading Advisor to these Series.

The Long Only Commodity Series, through the Trading Company in which the assets of the Long Only Commodity Series have been allocated, have entered into various Swaps with one or more swap counterparties. The Swaps enable the Long Only Commodity Series to earn returns similar to returns (less the fees and expenses of the Long Only Commodities Series, including the expenses associated with the Swaps) of the Thompson Reuters/Jefferies CRB Index (the "RJ/CRB Index"), and the Jefferies Commodity Performance Index (the "JCPI"). Specifically, the Trading Company, which will hold the assets allocable to the Long Only Commodity Series, will enter into Swaps linked to the RJ/CRB Index and the JCPI at the direction of the Managing Owner.

Indemnifications [Abstract]

Indemnifications

10. Indemnifications

The Trust has entered into agreements, which provide for the indemnification of futures clearing brokers, and commodity trading advisers, among others, against losses, costs, claims and liabilities arising from the performance of their individual obligations under such agreements, except for gross negligence or bad faith. The Trust has had no prior claims or payments pursuant to these agreements. The Trust's individual maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Trust that have not yet occurred. However, based on experience the Trust expects the risk of loss to be remote.

(1) Interest income and expenses per unit are calculated by dividing these amounts by the average number of units outstanding during the period.

The net gain/(loss) on investments, net of non-controlling interests is a balancing amount necessary to reconcile the change in net asset value per unit with the other per unit information.

(2) Computed using average net assets outstanding during the period. An owner's total returns may vary from the above returns based on the timing of contributions and withdrawals. Total returns are not annualized.

(3) Annualized

(4) Long Only Series Class 3 and Managed Futures Index Series Class 3 began trading operations on January 13, 2011.

(5) Formerly the Cambell/Graham/Tiverton Series.

(6) The Frontier Dynamic Series ceased trading operations on July 15, 2011 and redeemed all existing Units. The Series remains active. Net asset value per unit represents the liquidation value.

(7) For the three months ended September 30, 2011, 8.10% of the Currency Series' Class 1 total return and 1.31% of the Currency Series' Class 2 total return consists of a discretionary voluntary reimbursement by the managing owner for a realized investment loss. Excluding this item, total return would have been (11.79%) for Currency Series Class 1 and (1.90%) for Currency Series Class 2.

(1) Interest income and expenses per unit are calculated by dividing these amounts by the average number of units outstanding during the period.

The net gain/(loss) on investments, net of non-controlling interests is a balancing amount necessary to reconcile the change

in net asset value per unit with the other per unit information.

(2) Computed using average net assets outstanding during the period. An owner's total returns may vary from the above returns based on the timing of contributions and withdrawals. Total returns are not annualized.

(3) Annualized

(4) Long Only Series Class 3 and Managed Futures Index Series Class 3 began trading operations on January 13, 2011.

(5) Formerly the Cambell/Graham/Tiverton Series.

(6) The Frontier Dynamic Series ceased trading operations on July 15, 2011 and redeemed all existing Units. The Series remains active. Net asset value per unit represents the liquidation value.

(7) For the nine months ended September 30, 2011, 6.97% of the Currency Series' Class 1 total return and 2.40% of the Currency Series' Class 2 total return consists of a discretionary voluntary reimbursement by the managing owner for a realized investment loss. Excluding this item, total return would have been (16.11%) for Currency Series Class 1 and (5.54%) for Currency Series Class 2.

Trading Activities And Related Risks [Abstract]

Trading Activities And Related Risks

9. Trading Activities and Related Risks

The purchase and sale of futures and options on futures contracts require margin deposits with Futures Commission Merchants (each, an "FCM"). Additional deposits may be necessary for any loss on contract value. The Commodity Exchange Act requires an FCM to segregate all customer transactions and assets from the FCM's proprietary activities. A customer's cash and other property (for example, U.S. Treasury bills) deposited with an FCM are considered commingled with all other customer funds subject to the FCM's segregation requirements. In the event of an 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 term "off-balance sheet risk" refers to an unrecorded potential liability that, even though it does not appear on the statements of financial condition, may result in future obligation or loss in excess of the amount paid by the Series for a particular investment. Each Trading Company expects to trade in futures, options, forward and swap contracts and will therefore be a party to financial instruments with elements of off-balance sheet market and credit risk. In entering into these contracts, there exists a market risk that such contracts may be significantly influenced by market conditions, such as interest rate volatility, resulting in such contracts being less valuable. If the markets should move against all of the futures positions held by a Trading Company in respect of any Series at the same time, and if the Trading Advisor(s) of such Trading Company are unable to offset such futures interests positions, such Trading Company could lose all of its assets and the holders of Units of such Series would realize a 100% loss. The Managing Owner will seek to minimize market risk through real-time monitoring of open positions and the level of diversification of each Trading Advisor's portfolio. It is anticipated that any Trading Advisor's margin-to-equity ratio will typically not exceed approximately 35% although the actual ratio could be higher or lower from time to time.

In addition to market risk, trading futures, forward and swap contracts entails credit risk in that a counterparty will not be able to meet its obligations to a Trading Company. The counterparty for futures contracts traded in the United States and on most foreign exchanges is the clearinghouse associated with such exchange. In general, clearinghouses are backed by the corporate members of the clearinghouse who are required to share any financial burden resulting from the non-performance by one of their members and, as such, should significantly reduce this credit risk. In cases where the clearinghouse is not backed by the clearing members, like some foreign exchanges, it is normally backed by a consortium of banks or other financial institutions. Some non-U.S. exchanges, in contrast to U.S. exchanges, are principals' markets in which performance is the responsibility only of the individual counterparty with whom the Trading Company has entered into the transaction, and not of the exchange or clearing corporation. In these kinds of markets, there is risk of bankruptcy or other failure or refusal to perform by the counterparty.

In the case of forward contracts traded on the interbank market and swaps, neither is traded on exchanges. The counterparty is generally a single bank or other financial institution, rather than a group of financial institutions; thus there may be a greater counterparty credit risk. The Managing Owner expects the Trading Advisors to trade only with those counterparties which it believes to be creditworthy. All positions of each Trading Company will be valued each day on a mark-to-market basis. There can be no assurance that any clearing member, clearinghouse or other counterparty will be able to meet its obligations to any Trading Company.

The Managing Owner has established procedures to actively monitor and minimize market and credit risks. The Limited Owners bear the risk of loss only to the extent of the market value of their respective investments and, in certain specific circumstances, distributions and redemptions received.

Organization [Abstract]

Organization

1. Organization

The Frontier Fund, which is referred to in this report as the Trust, was formed on August 8, 2003, as a Delaware statutory trust. The Trust is a multi-advisor commodity pool, as described in Commodity Futures Trading Commission (the "CFTC") Regulation § 4.10(d)(2). The Trust has authority to issue separate series, or each, a Series, of units of beneficial interest (the "Units") pursuant to the requirements of the Delaware Statutory Trust Act, as amended (the "Trust Act"). The assets of each Series are valued and accounted for separately from the assets of other Series. The Trust is not registered as an investment company under the Investment Company Act of 1940, as amended (the "Investment Company Act"). It is managed by its Managing Owner, Equinox Fund Management, LLC.

Purchasers of Units are limited owners of the Trust ("Limited Owners") with respect to beneficial interests of the Series' Units purchased. The Trust Act provides that, except as otherwise provided in the amended and restated declaration of trust and trust agreement of the Trust dated as of August 8, 2003, by and among the Managing Owner, Wilmington Trust Company as trustee and the unitholders from time to time (the "Trust Agreement"), unitholders in a Delaware statutory trust will have the same limitation of liability as do stockholders of private corporations organized under the General Corporation Law of the State of Delaware. The Trust Agreement confers substantially the same limited liability, and contains the same limited exceptions thereto, as would a limited partnership agreement for a Delaware limited partnership engaged in like transactions as the Trust. In addition, pursuant to the Trust Agreement, the Managing Owner of the Trust is liable for obligations of a Series in excess of that Series' assets. Limited Owners do not have any such liability. The Managing Owner will make contributions to Series of the Trust necessary to maintain at least a 1% interest in the aggregate capital, profits and losses of all Series.

The Trust has been organized to pool assets of investor funds for the purpose of trading in the United States ("U.S.") and international markets for currencies, interest rates, stock indices, agricultural and energy products, precious and base metals and other commodities. The Trust may also engage in futures contracts, forwards, option contracts and other interest in derivative instruments, including swap contracts ("Swaps").

The Trust has eleven (11) separate and distinct Series of Units issued and outstanding: Frontier Diversified Series, Frontier Dynamic Series (closed to outside investors effective July 15, 2011 and existing outside investors liquidated as of July 15, 2011), Frontier Long/Short Commodity Series, Frontier Masters Series, Balanced Series, Berkeley/Graham/Tiverton Series (formerly Campbell/Graham/Tiverton Series), Currency Series, Long Only Commodity Series, Managed Futures Index Series, Winton Series and Winton/Graham Series (each a "Series" and collectively, the "Series"). The Trust may issue additional Series of Units.

The Trust, with respect to each Series:

• engages in the speculative trading of a diversified portfolio of futures, forward (including interbank foreign currencies), options contracts and other derivative instruments (including swap contracts), and may, from time to time, engage in cash and spot transactions;

• allocates funds to a limited liability trading company or companies ("Trading Company"). Except as otherwise described in these notes, each Trading Company has one-year renewable contracts with its own independent commodity trading advisor(s), or each, a Trading Advisor, that will manage all or a portion of such Trading Company's assets and make the trading decisions for the assets of each Series vested in such Trading Company. Each Trading Company will segregate its assets from any other Trading Company;

• maintains separate, distinct records for each Series, and accounts for the assets of each Series separately from the other Series;

• calculates the Net Asset Value ("NAV") of its Units for each Series separately from the other Series;

• has an investment objective of increasing the value of each Series' Units over the long term (capital appreciation), while controlling risk and volatility; further, to offer exposure to the investment programs of individual Trading Advisors and to specific instruments (currencies);

• maintains each Series of Units in three or six sub-classes—Class 1, Class 1a, Class 2, Class 2a, Class 3, and Class 3a. Investors who have purchased Class 1 or Class 1a Units of any Series are charged a service fee of up to three percent (3.0%) annually of the NAV of each Unit purchased, for the benefit of Selling Agents selling such Class 1 or Class 1a Units. The initial service fee, which is amortized monthly at an annual rate of up to three percent (3.0%) of the average daily NAV of Class 1 or Class 1 a of such Series, is prepaid to Equinox Fund Management, LLC (the "Managing Owner") by each Series, and paid to the selling agents by the Managing Owner in the month following sale; provided, however, that investors who redeem all or a portion of their Class 1 or Class 1 a Units of any Series during the first twelve (12) months following the effective date of their purchase are subject to a redemption fee of up to three percent (3.0%) of the NAV at which such investor redeemed to reimburse the Managing Owner for the then-unamortized balance of the prepaid initial service fee. With respect to Class 2 and Class 2a Units of any Series, the Managing Owner pays an ongoing service fee to Selling Agents of up to one half percent (0.5%) annually of the NAV of each Class 2 or Class 2a Unit (of which 0.25% will be charged to Limited Owners holding Class 2 Units of the Frontier Diversified Series, Frontier Dynamic Series and Frontier Masters Series or Class 2a Units of the Frontier Long/Short Commodity Series) sold until such Class 2 or Class 2a Units which are subject to the fee limitation are reclassified as Class 3 or Class 3a Units of the applicable Series. The Managing Owner may also pay Selling Agents certain additional fees and expenses for administrative and other services rendered and expenses incurred by such Selling Agents; and

• all payments made to Selling Agents who are members of the Financial Industry Regulatory Authority, Inc. ("FINRA") and their associated persons that constitute underwriting compensation will be subject to the limitations set forth in Rule 2310(b)(4)(B)(ii) (formerly Rule 281 0(b)(4)(B)(ii)) of the Conduct Rules of FINRA ("Rule 2310"). An investor's Class 1 Units or Class 2 Units of any Series, or Class 1a Units or Class 2a Units of the Frontier Long/Short Commodity Series or Balanced Series will be classified as Class 3 or Class 3a Units of such Series, as applicable, when the Managing Owner determines that the fee limitation set forth in Rule 2310 with respect to such Units has been reached or will be reached. No service fees are paid with respect to Class 3 or Class 3a Units. Units of any Class in a Series may be redeemed, in whole or in part, on a daily basis, at the then current NAV per Unit for such Series on the day of the week after the date the Managing Owner is in receipt of a redemption request for at least one (1) Business Day to be received by the Managing Owner prior to 4:00 PM in New York.

The assets of any particular Series include only those funds and other assets that are paid to, held by or distributed to the Trust on account of and for the benefit of that Series. Under the "Inter-Series Limitation on Liability" expressly provided for under Section 3804(a) of the Trust Act, separate and distinct records of the cash and equivalents, although pooled for maximizing returns, is maintained in the books and records of each Series.

As of September 30, 2011, each of the Long Only Commodity Series, Managed Futures Index Series and Winton Series has invested a portion of its assets in a single Trading Company. A single Trading Advisor manages 100% of the assets invested in each such Trading Company, except the Trading Company for the Long Only Commodity Series which allocates assets only to Swaps. The Currency Series invests a portion of its assets in a single Trading Company, which allocates assets to one Trading Advisor and one Swap. Each of the Frontier Diversified Series, Frontier Long/Short Commodity Series, Frontier Masters Series, Balanced Series, Berkeley/Graham/Tiverton Series, and Winton/Graham Series have invested a portion of its assets in several different Trading Companies and have multiple Trading Advisors that manage the assets invested in such Trading Companies.

In November 2010, the Berkeley/Graham/Tiverton Series invested a portion of its assets in Berkeley Quantitative Colorado Fund, LLC, an unaffiliated company, managed by an affiliate of Berkeley Quantitative L.P. Through this investment, Berkeley Quantitative L.P. became a commodity trading advisor to the Series.

During July, 2011, Currency Series liquidated its interest in an option basket and realized a decrease in fair value greater than had previously been recorded as unrealized loss. The Managing Owner determined to make a one time administrative adjustment by payment to the Currency Series of $390,589 to reimburse the effect of the loss on the investors in the series, exclusive of the inter-series payables' interests, recorded in the Statements of Operations as Net increase from payments by managing owner.

Fair Value Measurements [Abstract]

Fair Value Measurements

3. Fair Value Measurements

In connection with the valuation of investments the Series apply ASC 820. ASC 820 provides clarification that when a quoted price in an active market for the identical asset or liability is not available, a reporting entity is required to measure fair value using certain techniques. ASC 820 also clarifies that when estimating the fair value of an asset or liability, a reporting entity is not required to include a separate input or adjustment to other inputs relating to the existence of a restriction that prevents the transfer of an asset or liability. ASC 820 also clarifies that both a quoted price in an active market for the identical asset or liability at the measurement date and the quoted price for the identical asset or liability when traded as an asset in an active market when no adjustments to the quoted price of the asset are required are Level 1 fair value measurements.

Level 1 Inputs

Unadjusted quoted prices in active markets for identical financial assets that the reporting entity has the ability to access at the measurement date.

Level 2 Inputs

Inputs other than quoted prices included in Level 1 that are observable for the financial asset or liabilities, either directly or indirectly. These might include quoted prices for similar financial assets in active markets, quoted prices for identical or similar financial assets in markets that are not active, inputs other than quoted prices that are observable for the financial asset or inputs that are derived principally from or corroborated by market data by correlation or other means.

Level 3 Inputs

Unobservable inputs for determining the fair value of financial assets that reflect an entity's own assumptions about the assumptions that market participants would use in pricing the financial asset.

The Trust uses the following methodologies to value instruments within its financial asset portfolio at fair value:

Trading Securities. These instruments include U.S. Treasury securities and open trade equity positions (futures contracts and currency forwards) that are actively traded on public markets with quoted pricing for corroboration. U.S. Treasury securities, futures contracts, and currency forwards are reported at fair value using Level 1 inputs. Trading securities instruments further include open trade equity positions (trading options) that are quoted prices for identical or similar assets that are not traded on active markets. Trading options are reported at fair value using Level 2 inputs.

Swap Contracts. Certain Series of the Trust strategically invest a portion or all of their assets in total return Swaps, selected at the direction of the Managing Owner. Each Series also owns a portion of the Credit Default Swaps ("CDS") based upon ownership percentages of the cash management pool. Swaps are privately negotiated contracts designed to provide investment returns linked to those produced by one or more investment products or indices. In a typical Swap, two parties agree to exchange the returns (or differentials in rates of return) earned or realized on one or more particular predetermined investments or instruments. The gross returns to be exchanged or "swapped" between the parties are calculated with respect to a "notional amount" (i.e., the amount of value of the underlying asset used in computing the particular interest rate, return, or other amount to be exchanged) in a particular investment, or in a "basket" of securities. The valuation of swap contracts requires significant estimates. Certain Swap contracts are reported utilizing Level 2 inputs. These Swap contracts are reported at fair value based on daily reports from the swap counterparty that may be corroborated against independent valuation/rate of return information published and available on a daily recurring frequency. Swap contracts utilizing Level 2 inputs are reported at fair value based on daily reports from the swap counterparty that may be corroborated against independent valuation/rate of return information published and available on a daily recurring frequency. Other Swap contracts are reported utilizing Level 3 Inputs. Swap Contracts are reported at fair value based upon a weekly indicative value that is calculated by management using bid/ask prices from the counterparty. This fair value is corroborated by a daily range of valuations provided by a third party pricing service. The third party pricing service utilizes a Black Scholes pricing model with input adjustments factoring in volatility and liquidity of the instruments. All valuation processes are monitored by the valuation committee of the Managing Owner.

Investment in Unconsolidated Trading Companies. This investment represents the fair value of the allocation of cash, futures, forwards, options and swaps to each respective Series relative to its trading allocations from unconsolidated Trading Companies. The Trust, under the same management as the Trading Companies, has access to the underlying positions of the Trading Companies. As such, the Series report investments in unconsolidated Trading Companies at fair value using the corresponding inputs of the underlying securities of the Trading Companies which results in the Series reporting the corresponding Level determination from the inputs of the Trading Company.

Investment in the Berkeley Quantitative Colorado Fund, LLC. Investment in Berkeley Quantitative Colorado Fund, LLC is valued based on the daily net asset value as reported by the managing member of the Berkeley Quantitative Colorado Fund, LLC. The reported net asset value represents fair value based on observable data such as ongoing redemption and/or subscription activity, which is reported as a Level 2 input.

Inter-Series Receivables and Payables. The Balanced Series, for the purposes of diversification of investments and trading advisors through the other Series' access to Trading Companies in which the Balanced Series does not have a direct interest, advanced funds to the Currency Series and Frontier Dynamic Series. As of September 30, 2011, all inter-Series receivables and payables have been settled. Inter-Series receivables and payables were reported at fair value using Level 1 inputs.

The following table summarizes the instruments that comprise the Trust's financial asset portfolio, by Series, measured at fair value on a recurring basis as of September 30, 2011 and December 31, 2010, segregated by the level of valuation inputs within the fair value hierarchy utilized to measure fair value:
