Part II

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 Financial 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) for the Trust and each Series as of December 31, 2007 (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 Financial 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.

Report on Management’s Assessment of Internal Control over Financial Reporting

The management of the Managing Owner is responsible for establishing and maintaining adequate internal control over financial reporting by the Trust. The Managing Owner’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States. The internal control over financial reporting for the Trust and each Series includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of assets; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with accounting principles generally accepted in the United States, and that receipts and expenditures are being made only in accordance with authorizations of the management of the Managing Owner; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of assets that could have a material effect on the financial statements of the Trust or any Series.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. All internal control systems, no matter how well designed, have inherent limitations, including the possibility of human error and the circumvention of overriding controls. Accordingly, even effective internal control over financial reporting can provide only reasonable assurance with respect to financial statement preparation. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Management assessed the effectiveness of the internal control over financial reporting for the Trust and each Series as of December 31, 2007, based on the framework set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in its report entitled Internal Control-Integrated Framework. Based on that assessment, management concluded that, as of December 31, 2007, the internal control over financial reporting for the Trust and each Series is effective based on the criteria established in Internal Control-Integrated Framework.

This annual report does not include an attestation report of the Trust’s registered public accounting firm regarding internal control over financial reporting. Management’s report was not subject to attestation by the Trust’s registered public accounting firm pursuant to temporary rules of the SEC that permit the Trust to provide only management’s report in this annual report.

Equity interest is defined as Trading Level, which is the aggregate amount of predetermined investment levels which all Trading Advisors in the Trading Company have been authorized to trade, plus the accumulated profit or loss in the accounts. Investments in Trading Companies in which a Series does not have a controlling or majority interest are accounted for under the equity method and are carried in the statement of financial condition of such Series at fair value. Fair value represents the investment in the Trading Company and the proportionate share of the Trading Company’s income or loss.

The following table details the percentage equity interest of each Series in each Trading Company as of December 31, 2007 and December 31, 2006.

The Trading Companies engage in the speculative trading of a diversified portfolio of futures, forward (including interbank foreign currencies) and options contracts and other derivative instruments and may, from time to time, engage in cash and spot transactions. A brief description of the Trust’s main types of investments is set forth below:

2. Critical Accounting Polices

The following are the significant accounting policies of the Trading Companies. The Trading Companies follow the same significant accounting policies as the Trust.

Basis of Presentation—The financial statements of each Trading Company included herein have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”).

The Trading Companies have elected not to provide statements of cash flows as permitted by Statement of Financial Accounting Standards No. 102Statements of Cash Flows—Exemption of Certain Enterprises and Classification of Cash Flows from Certain Securities Acquired for Resale.

Cash held at Futures Commodity Merchants—The Trading Companies deposit assets with a broker subject to CFTC regulations and various exchange and broker requirements. Margin requirements are satisfied by the deposit of cash with such broker. The Trading Companies earn interest income on its assets deposited with the broker.

Use of Estimates—The preparation of financial statements in conformity with generally accepted accounting principles requires Equinox Fund Management, LLC, the managing owner of the Trust and the manager of each of the Trading Companies (the “Managing Owner”), to make estimates and assumptions that affect 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. Actual results could differ from those estimates.

Revenue recognition—Futures, options on futures, and forward contracts are recorded on a trade date basis and realized gains or losses are recognized when contracts are liquidated. Unrealized gains or losses on open contracts (the difference between contract trade price and market price) are reported in the Statement of Operations as a Net change in open trade equity, as there exists a right of offset of unrealized gains or losses in accordance with the Financial Accounting Standards Board (“FASB”) Interpretation No. 39—“Offsetting of Amounts Related to Certain Contracts.” Any change in net unrealized gain or loss from the preceding period is reported in the

Statement of Operations. Market value of exchange-traded contracts is based upon exchange settlement prices. Market value of non-exchange-traded contracts is based on third party quoted dealer values on the interbank market.

Distribution of Earnings—Each Trading Company distributes all of its daily trading profits or losses to the Series in proportion to each Series’ ownership interest in the Trading Company, adjusted on a daily basis. As of December 31, 2007, 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.

Foreign Currency Transactions—The Trading Companies functional currency is the U.S. Dollar, however, it transacts business in currencies other than the U.S. Dollar. Assets and liabilities denominated in currencies other than the U.S. Dollar are translated into U.S. Dollars at the rates in effect at the date of the statement of financial condition. Income and expense items denominated in currencies other than the U.S. Dollar are translated into U.S. Dollars at the rates in effect during the period. Gains and losses resulting from the translation to U.S. Dollars are reported in income currently.

Investments and Swaps—The Trading Companies records investment transactions on trade date 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. Generally, fair values will be based on quoted market prices; however, in certain circumstances, significant judgments and estimates may be required in determining fair value in the absence of an active market closing price. At December 31, 2007 all investments in futures and forward contracts were based on quoted market prices. The valuation of investments in swap contracts (“Swaps”) involve estimates.

Income Taxes—No provision for income taxes has been made in these financial statements as the results of operations of the Trading Companies are consolidated with the Trust for income tax purposes. Each Limited Owner of the Trust is individually responsible for reporting income or loss based on their respective share of the Trust’s income and expenses as reported for income tax purposes. In June 2006, the FASB issued Interpretation No. 48 (FIN 48), Accounting for Uncertainty in Income Taxes, an Interpretation of FASB Statement No. 109. This Interpretation clarifies the accounting and financial statement reporting for uncertainty in income taxes recognized by prescribing a recognition threshold and measurement attributable for a tax position taken or expected to be taken in a tax return. The Interpretation was originally effective for fiscal years beginning after December 15, 2006; however, on February 1, 2008, FASB issued Staff Position No. FIN 48-2, which deferred the effective date to annual financial statements for fiscal years beginning after December 15, 2007 for nonpublic companies. The adoption of FIN 48 was effective for the Trading Companies on January 1, 2007, and did not impact the Trading Companies’ financial position or results of operations.

Fees and Expenses—The Trading Companies incur no expenses other than trading commissions resulting from normal trading activity. All operating expenses such as legal, accounting, etc. are immaterial and paid for, without reimbursement, by the Managing Owner.

Recent Accounting Pronouncements—In September 2006, the FASB issued SFAS No. 157, Fair Value Measurements (“SFAS 157”). SFAS 157, which, among other things, defines fair value, establishes a framework for measuring fair value and enhances disclosures about fair value measurements required under other accounting pronouncements, but does not change existing guidance as to whether or not an instrument is carried at fair value. SFAS 157 is effective for the Trust January 1, 2008 and management does not expect that the adoption of this Statement will have a material impact on its financial statements.

In February 2007, the FASB issued SFAS No. 159, The Fair Value Option for Financial Assets and Financial Liabilities (“SFAS 159”), which permits entities to choose to measure many financial instruments and certain other items at fair value that are not currently required to be measured at fair value. SFAS 159 is effective for the Trust on January 1, 2008. Management is currently evaluating the provisions of SFAS 159 and its potential effects on its financial statements.

In April 2007, the FASB issued Interpretation No. 39-1,Amendment of FASB Interpretation No. 39(“FIN 39-1”). FIN 39-1 defines “right of setoff” and specifies what conditions must be met for a derivative contract to qualify for this right of setoff. It also addresses the applicability of a right of setoff to derivative instruments and clarifies the circumstances in which it is appropriate to offset amounts recognized for those instruments in the Statements of Financial Condition. In addition, FIN 39-1 permits offsetting of fair value amounts recognized for multiple derivative instruments executed with the same counterparty under a master netting arrangement and fair value amounts recognized for the right to reclaim cash collateral (a receivable) or the obligation to return cash collateral (a payable) arising from the same master netting arrangement as the derivative instruments. This interpretation is effective for fiscal years beginning after November 15, 2007. The adoption of FIN 39-1 on January 1, 2008 is not expected to have a material impact on the Trading Companies’ Financial Statements.

In March 2008, the FASB issued Statement of Financial Accounting Standards No. 161,Disclosure about Derivative Instruments and Hedging Activities, an Amendment of FASB Statement No. 133 (“SFAS No. 161”). SFAS No. 161 is intended to improve transparency in financial reporting by requiring enhanced disclosures of an entity’s derivative instruments and hedging activities and their effects on the entity’s financial position, financial performance, and cash flows. SFAS No. 161 applies to all derivative instruments within the scope of SFAS No. 133. It also applies to non-derivative hedging instruments and all hedged items designated and qualifying as hedges under SFAS No. 133. SFAS No. 161 amends the current qualitative and quantitative disclosure requirements for derivative

instruments and hedging activities set forth in SFAS No. 133 and generally increases the level of desegregations that will be required in an entity’s financial statements. SFAS No. 161 requires qualitative disclosures about objectives and strategies for using derivatives, quantitative disclosures about fair value amounts of gains and losses on derivative instruments, and disclosures about credit-risk related contingent features in derivative agreements. SFAS No. 161 is effective prospectively for financial statements issued for fiscal years and interim periods beginning after November 15, 2008. Management is currently evaluating the provisions of SFAS 161 and its potential effect on its Financial Statements.

In applying these policies, the Managing Owner may make judgments that may require estimates about matters that are inherently uncertain.

3. Swaps

In addition to authorizing Trading Advisors to manage pre-determined investment levels of futures and forward contracts, certain Trading Companies 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. 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 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 Trading Companies’ investment in Swaps will likely differ substantially over time due to cash flows, portfolio management decisions and market movements.

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 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.

Frontier Trading Company I LLC, Frontier Trading Company III LLC and Frontier Trading Company VI LLC 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, the swap counterparty to the Trading Company of these Series is not a Trading Advisor to these Trading Companies.

Frontier Trading Company VIII, LLC has entered into various Swaps with one or more swap counterparties. The Swaps earn returns similar to returns of the Reuters/Jefferies CRB Index (the “RJ/CRB Index”), and the Jefferies Commodity Performance Index (the “JCPI”).

The Trading Companies have invested in the following Swaps as of December 31, 2007:

4. 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 Statement 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 unrealized gain (loss) on open futures contracts is comprised of the following:

The Managing Owner has established procedures to actively monitor and minimize market and credit risks. Investors in units of the Frontier Fund Series 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.

5. Indemnifications

The Trading Companies have entered into agreements, which provide for the indemnification of futures clearing brokers, currency trading companies, and commodity trading advisors, 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 Trading Companies have had no prior claims or payments pursuant to these agreements. The Trading Companies’ individual maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Trading Companies that have not yet occurred. However, based on experience the Managing Owner expects the risk of loss to be remote.
