Equinox Frontier Funds

AFFIRMATION OF THE COMMODITY POOL OPERATOR

To the best of the knowledge and belief of the undersigned, the information contained in the attached financial statements for the years ended December 31, 2014 and 2013 is accurate and complete.

Table of Contents

Part I

Overview

Equinox Frontier Funds, 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”). ItThe Trust is managed by Equinox Fund Management, LLC (the “Managing Owner”).

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 second amended and restated declaration of trust and trust agreement dated December 9, 2013, by and among the Managing Owner, Wilmington Trust Company as trustee and the unitholders, as amended 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 the Series of the Trust necessary to maintain at least a 1% interest in the aggregate capital, profits and losses of all Series.the combined Series of the Trust.

The Trust has been organized to pool 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 six (6)seven (7) separate and distinct Series of Units issued and outstanding: Equinox Frontier Diversified Fund, Equinox Frontier Masters Fund, Equinox Frontier Long/Short Commodity Fund, Equinox Frontier Balanced Fund, Equinox Frontier Select Fund, Equinox Frontier Winton Fund, and Equinox Frontier Heritage Fund, (each a “Series” and collectively, the “Series”). The Trust financial statements are comprised of unitized Series which are consolidated into the Trust financial statements. However, the consolidated Trust does not issue units.

The Trust, with respect to each Series:

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 Equinox Frontier Diversified Fund, and Equinox Frontier Masters Fund or Class 2a Units of the Equinox Frontier Long/Short Commodity Fund sold)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

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, isare maintained in the books and records of each Series.

As of December 31, 2014,2015, the total Units outstanding of each Series of the Trust was 500,842 with respect towere 446,825 for the Equinox Frontier Diversified Fund, 139,604 with respect to115,094 for the Equinox Frontier Long/Short Commodity Fund, 212,533 with respect to192,324 for the Equinox Frontier Masters Fund, 705,682 with respect to639,721for the Equinox Frontier Balanced Fund, 155,534 with respect to140,811 for the Equinox Frontier Select Fund, 211,024 with respect to195,082 for the Equinox Frontier Winton Fund and 93,534 with respect to86,329 for the Equinox Frontier Heritage Fund.

Each of the Equinox Frontier Diversified Fund, Equinox Frontier Long/Short Commodity Fund, Equinox Frontier Masters Fund, Equinox Frontier Balanced Fund, Equinox Frontier Select Fund, Equinox Frontier Winton Fund, and Equinox Frontier Heritage Fund has invested a portion of its assets in several different Trading Companies and has multiple Trading Advisors that manage the assets invested in such Trading Companies.

During July 2012, Equinox Frontier Long/Short Commodity Fund Class 1 Units and Equinox Frontier Balanced Fund Class 1a Units ceased trading operations and all remaining Units were exchanged for Class 3 Units and Class 3a Units, respectively.

As of December 9, 2013, the Balanced Series of the Trust became known as the Equinox Frontier Balanced Fund, the Frontier Diversified Series of the Trust became known as the Equinox Frontier Diversified Fund, the Frontier Heritage Series became known as Equinox Frontier Heritage Fund, the Frontier Long/Short Commodity Series became known as the Equinox Frontier Long/Short Commodity Fund, the Frontier Masters Series became known as the Equinox Frontier Masters Fund, the Frontier Select Series became known as the Equinox Frontier Select Fund, and the Winton Series became known as the Equinox Frontier Winton Fund.

Trading Advisors are responsible for the trading decisions of the respective Trading Companies for which they trade. It is expected that between 10% and 30% of each Series’ assets normally will be invested in one or more Trading Companies to be committed as margin for trading positions but from time to time these percentages may be substantially more or less. The remainder of each Series’ assets is maintained at the Trust level for cash management. Each of the respective Series has invested monies into pooled cash management assets which have included purchases of custom time deposits, U.S. Treasury securities and credit default swaps. Each Series’ ownership in these investments is based on its percentage ownership in the pooled cash management assets on the reporting date.

The Trading Advisors were selected based upon the Managing Owner’s evaluation of each Trading Advisor’s past performance, trading portfolios and strategies, as well as how each Trading Advisor’s performance, portfolio and strategies complement and differ from those of the other Trading Advisors. As of December 31, 2014,2015, none of the Trading Advisors or any of their principals had any beneficial interest in the Trust, but any of them are free to acquire such beneficial interest.

Equinox Fund Management, LLC, a Delaware limited liability company formed in June 2003, is the managing owner of the Trust (the “Managing Owner”). The Managing Owner became registered with the Commodity Futures Trading Commission (“CFTC”) as a commodity pool operator (“CPO”), as of August 6, 2003, and has been a member of the National Futures Association (the “NFA”) in such capacity since that date. The Managing Owner’s main business office is located at 1775 Sherman Street, Suite 2500, Denver, Colorado 80203, telephone (303) 837-0600. A description of the Managing Owner’s responsibilities to the Trust is contained in a

Prospectus dated April 30, 2014,2015, filed with the SEC on May 7, 2014April 30, 2015 pursuant to Rule 424(b)(3) of the Securities Act of 1933, as amended (File No. 333-185695), which is referred to herein as the “Prospectus,” under the section captioned “The Managing Owner,” and such description is incorporated herein by reference from the Prospectus.

Regulation

Under the Commodity Exchange Act, as amended, (the “Commodity Exchange Act”) commodity exchanges and commodity futures trading are subject to regulation by the CFTC. The NFA, a registered futures association under the Commodity Exchange Act, is the only non-exchange self-regulatory organization for commodity industry professionals. The CFTC has delegated responsibility to the NFA for the registration of “commodity trading advisors,” “commodity pool operators,” “futures commission merchants,” “introducing brokers” and their respective “associated persons” and “floor brokers.” The Commodity Exchange Act requires “commodity pool operators,” such as the Managing Owner, “commodity trading advisors,” and commodity brokers or “futures commission merchants,” such as the Trust’s commodity brokers, to be registered and to comply with various reporting and recordkeeping requirements. The Managing Owner and the Trust’s commodity brokers are members of the NFA. The CFTC may suspend a commodity pool operator’s or a commodity trading advisor’s registration if it finds that its trading practices tend to disrupt orderly market conditions, or as the result of violations of the Commodity Exchange Act or rules and regulations promulgated thereunder. In the event that the Managing Owner’s registration as a commodity pool operator were terminated or suspended, the Managing Owner would be unable to continue to manage the business of the Trust. Should the Managing Owner’s registration be suspended, termination of the Trust may result.

In addition to such registration requirements, the CFTC and certain commodity exchanges have established limits on the maximum net long and net short positions that any person, including the Trust, may hold or control in particular commodities. Most exchanges also limit the maximum changes in futures contract prices that may occur during a single trading day. The Trust also trades in dealer markets for forward and swap contracts, which are not regulated by the CFTC. Federal and state banking authorities also do not regulate forward trading or forward dealers. In addition, the Trust trades on foreign commodity exchanges, which are not subject to regulation by any U.S. government agency.

Operations

A description of the business of the Trust, including trading approaches for each Series of Units, rights and obligations of the limited owners, compensation arrangements and fees and expenses is contained in the Prospectus, under the sections captioned “Risk Disclosure Statement,” “Summary,” “Risk Factors,” “Equinox Funds Trust,” “The Offering,” “Trading Limitations, Policies and Swaps,” “The Trustee,” “The Managing Owner,” “Actual and Potential Conflicts of Interest,” “Fees and Expenses” and the appendix attached to the Prospectus for each Series of Units, and such description is incorporated herein by reference from the Prospectus.

The Trading Companies for each Series of Units engage in the speculative trading of a diversified portfolio of futures, forwards (including interbank foreign currencies), options contracts and other derivative instruments (including Swaps) 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:

Certain of the Trading Companies have entered into contractual arrangements with independent commodity trading advisors that will manage all or a portion of such Trading Company’s assets and make the trading decisions with respect to the assets of such Trading Company.

Selection and Replacement of Trading Advisors

The managing owner is responsible for the selection, retention and termination of the trading advisors and reference programs on behalf of each series. The actual allocation among trading advisors for each series will vary based upon the relative trading

performance of the trading advisors and/or reference programs, and the managing owner may otherwise vary such percentages from time to time in its sole discretion. The managing owner will adjust its allocations and rebalance the portfolio of any series among trading advisors to maintain weightings that it believes will most likely achieve capital growth within the investment guidelines of the relevant series.

The managing owner utilizes certain quantitative and qualitative analysis in connection with the identification, evaluation and selection of the trading advisors. The managing owner’s proprietary and commercial analytical software programs and comprehensive trading advisor database provide the quantitative basis for the trading advisor selection, portfolio implementation process, and ongoing risk management, monitoring, and review.

In 1983, Richard Bornhoft, the Chief Investment Officer of the managing owner, began compiling a proprietary database of the leading United States and internationally based alternative investment programs. Trading advisors are monitored and performance data is entered on a daily, monthly, quarterly or bi-annual basis according to internal ranking systems.

The managing owner’s research department is continually refining ways to assimilate vast amounts of trading advisor performance data and due-diligence information. The proprietary and commercial database of alternative investment programs is always increasing. Research team members regularly interact with trading advisors throughout the due diligence and monitoring process. Only those programs that have met strict quantitative and qualitative review are considered as potential managers of client assets.

Following is a summary of the quantitative and qualitative analysis:

Quantitative Analysis

The managing owner’s analytical software system applies a variety of statistical measures towards the evaluation of current and historical advisor performance data. Statistical measures include but are not limited to: (1) risk/reward analysis, (2) time window analysis, (3) risk analysis, (4) correlation analysis, (5) statistical overlays and (6) performance cycle analysis.

Qualitative Analysis

Although quantitative analysis statistically identifies the top performing trading advisors, qualitative analysis plays a major role in the trading advisor evaluation and final selection process. Each trading advisor in the managing owner’s top decile universe initially undergoes extensive qualitative review by the managing owner’s research department, as well as continual monitoring. This analysis generally includes, but is not limited to: (1) preliminary information and due diligence, (2) background review, (3) onsite due diligence, (4) extensive due diligence questionnaires and (5) written review and periodic updates. This information allows a thorough review of each trading advisor’s trading philosophy, trading systems and corporate structure.

Multi-Manager Approach

A multi-manager approach to portfolio management provides diversification of trading advisors and access to broader global markets. Multiple trading advisors can provide diversification across trading methodologies, trading time horizons, and markets traded. Additionally, multi-manager portfolios tend to provide a greater level of professional management with ongoing risk management and review. The result can be more consistent returns with lower volatility.

The trading system of each of the major commodity trading advisors used by the Trading Companies is as follows:

A commodity trading advisor (“CTA”) that may be allocated at least 10% of the assets of any Series is referred to herein as a major CTA. A non-major CTA in respect of any Series is a CTA whose allocation will be less than 10% of such Series’ assets.

As of December 31, 2014,2015, the allocation of the assets of each applicable Series of the Trust between the Trading Advisors was as follows:

A description of the trading strategies of the major commodity trading advisors, including general trading focus and registration as a commodity pool operator and/or an investment adviser, and a description of the advisory agreements with the commodity trading advisors is contained in the Prospectus, under the section captioned “Summary of Agreements—Advisory Agreements” and the appendix attached to the Prospectus for each Series of Units, containing a description of each major commodity trading advisor and its trading program, and such description is incorporated herein by reference from the Prospectus.

Financial Information about Geographic Areas

Although the Trust trades in the global futures and forward markets, it does not have operations outside of the U.S., and therefore this item is not applicable.

Employees

The Trust has no employees. The Trust is managed solely by the Managing Owner in its capacity as the managing owner of the Trust pursuant to the Trust Agreement.

Additional Information

None.

The Trust is a venture in a high-risk business. An investment in the Units of each Series is very speculative. You should make an investment in one or more of the Series only after consulting with independent, qualified sources of investment and tax advice and only if your financial condition will permit you to bear the risk of a total loss of your investment. You should consider an investment in the Units only as a long-term investment. Moreover, to evaluate the risks of this investment properly, you must familiarize yourself with the relevant terms and concepts relating to commodities trading and the regulation of commodities trading, which are discussed in the Prospectus in the Statement of Additional Information below, in the section captioned “The Futures Markets,” which is incorporated herein by reference.

You should carefully consider all the information we have included or incorporated by reference in this Form 10-K and our subsequent periodic filings with the SEC. In particular, you should carefully consider the risk factors described below and read the risks and uncertainties as set forth in the “Management’s Discussion and Analysis of Financial Condition and Results of Operations” Section of this Form 10-K. Any of the following risks and uncertainties could materially adversely affect the Trust, its trading activities, operating results, financial condition and NAV and therefore could negatively impact the value of your investment. The information contained herein does not constitute investment, legal or tax advice. You should not invest in the Units unless you can afford to lose all of your investment.

Market Risks

The commodity interest markets in which the Trading Advisors trade are highly volatile, which could cause substantial losses and may cause you to lose your entire investment.

Commodity interest contracts are highly volatile and are subject to occasional rapid and substantial fluctuations. Consequently, you could lose all or substantially all of your investment in the Units of any Series should such Series’ trading positions suddenly turn unprofitable. The profitability of any Series depends primarily on the ability of its Trading Advisor(s) to predict these fluctuations accurately. Price movements for commodity interests are influenced by, among other things:

The Trading Advisors’ technical trading methods may not take account of these factors except as they may be reflected in the technical input data analyzed by the Trading Advisors.

In addition, governments from time to time intervene, directly and by regulation, in certain markets, often with the intent to influence prices directly. The effects of governmental intervention may be particularly significant at certain times in the financial instrument and currency markets, and this intervention may cause these markets to move rapidly.

Futures, forward and options trading is volatile and may cause large losses.

A principal risk in futures, forward and options trading is volatile performance. Because the trading decisions for the Equinox Frontier Winton Fund will be made by a single Trading Advisor, the trading for Equinox Frontier Winton Fund is similar to a single advisor fund in which one trading advisor makes all the trading decisions. In single advisor funds, volatility may increase as compared to a fund with several trading advisors who, collectively, can diversify risk to a greater extent (assuming those advisors are non-correlated with each other).

Options trading can be more volatile and expensive than futures trading.

Certain Trading Advisors may trade options on futures. Although successful options trading requires many of the same skills as successful futures trading, the risks involved are somewhat different. Successful options trading requires a trader to accurately assess near-term market volatility because that volatility is immediately reflected in the price of outstanding options. Correct assessment of market volatility can therefore be of much greater significance in trading options than it is in many long-term futures strategies. If market volatility is incorrectly predicted, the use of options can be extremely expensive.

The Trading Advisors’ trading is subject to execution risks.

Although each Series generally will purchase and sell actively traded contracts, orders may not be executed at or near the desired price, particularly in thinly traded markets, in markets that lack trading liquidity, or because of applicable “daily price fluctuation limits,” “speculative position limits” or market disruptions. If market illiquidity or disruptions occur, major losses could result.

Futures Interests trading is speculative and volatile.

The rapid fluctuations in the market prices of futures, forwards, and options make an investment in any of the series volatile. Volatility is caused by, among other things: changes in supply and demand relationships; weather; agriculture, trade, fiscal, monetary and exchange control programs; domestic and foreign political and economic events and policies; and changes in interest rates. The Trading Advisors’ technical trading methods may not take account of these factors except as they may be reflected in the technical input data analyzed by the trading advisors. In addition, governments from time to time intervene, directly and by regulation, in certain markets, often with the intent to influence prices directly. The effects of governmental intervention may be particularly significant at certain times in the financial instrument and currency markets, and this intervention may cause these markets to move rapidly.

Each Series’ performance will be volatile, and a Series could lose all or substantially all of its assets. The multi-advisor feature of each Series, except for Equinox Frontier Winton Fund, may reduce the return volatility relative of the performance of single-advisor investment funds.

Options are volatile and inherently leveraged, and sharp movements in prices could cause the Trust to incur large losses.

Certain Trading Advisors may trade options on futures. Although successful options trading requires many of the same skills as successful futures trading, the risks involved are somewhat different. Successful options trading requires a trader to accurately assess near-term market volatility, because that volatility is immediately reflected in the price of outstanding options. Correct assessment of market volatility can therefore be of much greater significance in trading options than it is in many long-term futures strategies. If market volatility is incorrectly predicted, the use of options can be extremely expensive.

Exchanges of futures for physicals may adversely affect performance.

Certain Trading Advisors may engage in exchanges of futures for physicals for client accounts. An exchange of futures for physicals is a transaction permitted under the rules of many futures exchanges in which two parties holding futures positions may close out their positions without making an open, competitive trade on the exchange. Generally, the holder of a short futures position buys the physical commodity, while the holder of a long futures position sells the physical commodity. The prices at which such transactions are executed are negotiated between the parties. If a Trading Advisor engaging in exchanges of futures for physicals were prevented from such trading as a result of regulatory changes, the performance of client accounts of such Trading Advisor could be adversely affected.

Cash flow needs may cause positions to be closed which may cause substantial losses.

Certain Trading Advisors may trade options on futures. Futures contract gains and losses are marked-to-market daily for purposes of determining margin requirements. Option positions generally are not marked-to-market daily, although short option positions will require additional margin if the market moves against the position. Due to these differences in margin treatment between futures and options, there may be periods in which positions on both sides must be closed down prematurely due to short term cash flow needs. If this occurs during an adverse move in a spread or straddle relationship, then a substantial loss could occur.

The Trading Companies and Trust may enter into Swap and similar transactions which may create risks.

Swaps are not traded on exchanges and are not subject to the same type of government regulation as exchange markets. As a result, many of the protections afforded to participants on organized exchanges and in a regulated environment are not available in connection with these transactions.

The Dodd-Frank Wall Street Reform and Consumer Protection Act, or the Dodd-Frank Act, will affect the manner in which OTC swap transactions are traded and the credit risk associated with such trading. Any changes will likely impact the way swaps are traded and could impact the trading strategy of the trust, as well as make it more expensive to trade swaps.

There are no limitations on daily price movements in swaps. Speculative position limits are not applicable to swaps, although the counterparties to swaps may limit the size or duration of positions as a consequence of credit considerations. Participants in the swap markets are not required to make continuous markets in the swaps they trade. Participants could refuse to quote prices for swaps or quote prices with an unusually wide spread between the price at which they are prepared to buy and the price at which they are prepared to sell. In the case of any swap that references a fund or program managed by a trading advisor, certain or all of the risks disclosed in this report in relation to the trading advisors also may apply, indirectly, in relation to the relevant series’ investment in such swap.

The trading on behalf of each Series will be margined, which means that sharp declines in prices could lead to large losses.

Because the amount of margin funds necessary to be deposited with a futures clearing broker to enter into a futures, forward contract or option position is typically about 2% to 10% of the total value of the contract, each Trading Advisor may take positions on behalf of a Series with face values equal to several times such Series’ NAV. These low margin requirements provide a large amount of leverage. As a result of margining, even a small movement in the price of a contract can cause major losses. Any purchase or sale of a futures or forward contract or option position may result in losses that substantially exceed the amount invested. If severe short-term price declines occur, such declines could force the liquidation of open positions with large losses. Margin is normally monitored through the margin-to-equity ratio employed by each trading advisor. Under normal circumstances, the Trading Advisors will vary between a 10% to 30% margin-to-equity ratio. In addition, OTC transactions present risks in addition to those associated with exchange-traded contracts, as discussed immediately below.

OTC transactions are subject to little, if any, regulation and may be subject to the risk of counterparty default.

A portion of each Series’ assets may be used to trade OTC derivative contracts, such as forward contracts, option contracts, or swaps, or spot contracts. OTC contracts are typically traded on a principal-to-principal basis through dealer markets that are dominated by major money center and investment banks and other institutions and are essentially unregulated by the CFTC. You therefore do not receive the protection of CFTC regulation or the statutory scheme of the Commodity Exchange Act in connection with this trading activity. The markets for OTC contracts rely upon the integrity of market participants in lieu of the additional regulation imposed by the CFTC on participants in the futures markets. The lack of regulation in these markets could expose a Series in certain circumstances to significant losses in the event of trading abuses or financial failure by participants.

Each Series also faces the risk of non-performance by the counterparties to the OTC contracts. Unlike in futures contracts, the counterparty to these contracts is generally a single bank or other financial institution, rather than a clearing organization backed by a group of financial institutions. As a result, there will be greater counterparty credit risk in these transactions. The clearing member, clearing organization or other counterparty may not be able to meet its obligations, in which case the applicable Series could suffer significant losses on these contracts.

The Dodd-Frank Act will affect the manner in which OTC swap transactions are traded and the credit risk associated with such trading. Depending upon actions taken by regulatory authorities, these changes may also affect the manner of trading of OTC foreign currency transactions. Transactions that have been entered into prior to implementation of the provisions of the Dodd-Frank Act will remain in effect. Accordingly, even after the new regulatory framework is fully implemented, the risks of OTC foreign exchange transactions will continue to exist with respect to transactions entered into prior to the implementation of the provisions of the Dodd-Frank Act. Additionally, any changes will likely impact the way swaps are traded and could impact the trading strategy of the trust, as well as make it more expensive to trade swaps.

Assets Held in Accounts at U.S. Banks May Not Be Fully Insured.

The assets of each trading company that are deposited with commodity brokers or their affiliates may be placed in deposit accounts at U.S. banks. The Federal Deposit Insurance Corporation (FDIC) insures deposit accounts at insured banks for up to $250,000 for each accountholder, and, if the funds in an account can be traced back to multiple individual co-owners, then each co-owner may be entitled to $250,000 in coverage. This amount of deposit insurance coverage was made permanent by the Dodd-Frank Act. Uninsured depositors also may receive funds in the event of a receivership of the bank holding the deposit accounts, but uninsured depositors have a lower priority in respect of payment than insured depositors or certain other creditors, and frequently there are insufficient funds in a receivership estate to pay off uninsured depositors fully or at all. If the FDIC were to become receiver of an insured U.S. bank holding deposit accounts that were established by a commodity broker or one of its affiliates, then it is uncertain whether the commodity broker, the affiliate involved, the trading company, the Series involved, or the investor would be able to reclaim cash in the deposit accounts in the full amount.

Your investment could be illiquid.

A Trading Advisor may not always be able to liquidate its commodity interest positions at the desired time or price. It is difficult to execute a trade at a specific price when there is a relatively small volume of buy and sell orders in a market. A market disruption, such as a foreign government taking political actions that disrupt the market in its currency or in a major export, can also make it difficult to liquidate a position. Alternatively, limits imposed by futures exchanges or other regulatory organizations, such as speculative position limits and daily price fluctuation limits, may contribute to a lack of liquidity with respect to some commodity interests. There is no secondary market for the Units and none is expected to develop.

Certain Restrictions on Redemption and Transfer of the Units Will Apply.

Investors may redeem units daily on one business day notice, but certain restrictions on redemption and transfer will apply. For example, if you invest in Class 1 or 1a Units and redeem all or a portion of such Units on or before the end of the 12 full months following the purchase of such Units, you will be charged a redemption fee of up to 2.0% of the purchase price of any such units being redeemed. Also, transfers of Units are permitted only with the prior written consent of the managing owner and provided that conditions specified in the trust agreement are satisfied. There is no secondary market for the Units and none is expected to develop.

Redemptions may be temporarily suspended.

The Managing Owner may temporarily suspend redemptions for some or all of the Series for up to 30 days if the effect of any redemption, either alone or in conjunction with other redemptions, would be to impair the Trust’s ability to operate in pursuit of its objectives (for example, if the Managing Owner believes a redemption, if allowed, would materially advantage one investor over another investor). The Managing Owner anticipates suspending redemptions only under extreme circumstances, such as a natural disaster, force majeure, act of war, terrorism or other event which results in the closure of financial markets. During any suspension of redemptions, a redeeming Limited Owner invested in a Series for which redemptions were suspended would remain subject to market risk with respect to such Series.

An investment in Units may not diversify an overall portfolio.

Historically, managed futures have performed in a manner largely independent from the general equity and debt markets. If, however, a Series does not perform in a non-correlated manner with respect to the general financial markets or does not perform successfully, you will obtain little or no diversification benefits by investing in the Units. An investment in any Series of the Trust could increase, rather than reduce your overall portfolio losses during periods when the Trust and the equity and debt markets decline in value. There is no way of predicting whether the Trust will lose more or less than stocks and bonds in declining markets. You should therefore not consider the Units to be a hedge against losses in your core stock and bond portfolios. Past performance is not indicative of future results.

Trading Risks

There are disadvantages to making trading decisions based on technical analysis.

Many of the Trading Advisors except certain Trading Advisors trading for the Equinox Frontier Long/Short Commodity Fund may base their trading decisions on trading strategies that use mathematical analyses of technical factors relating to past market performance rather than fundamental analysis. The buy and sell signals generated by a technical, trend-following trading strategy are derived from a study of actual daily, weekly and monthly price fluctuations, volume variations and changes in open interest in the markets. The profitability of any technical, trend-following trading strategy depends upon the occurrence in the future of significant, sustained price moves in some of the markets traded. A danger for trend-following traders is whip-saw markets, that is, markets in which a potential price trend may start to develop but reverses before an actual trend is realized. A pattern of false starts may generate repeated entry and exit signals in technical systems, resulting in unprofitable transactions. In the past, there have been prolonged periods without sustained price moves. Presumably these periods will continue to occur. Periods without sustained price moves may produce substantial losses for trend-following trading strategies. Further, any factor that may lessen the prospect of these types of moves in the future, such as increased governmental control of, or participation in, the relevant markets, may reduce the prospect that any trend- following trading strategy will be profitable in the future.

There are disadvantages to making trading decisions based on fundamental analysis.

Certain Trading Advisors will base their decisions on trading strategies which utilize in whole or in part fundamental analysis of underlying market forces. Fundamental analysis attempts to examine factors external to the trading market which affect the supply and demand for a particular commodity interest in order to predict future prices. Such analysis may not result in profitable trading because certain Trading Advisors may not have knowledge of all factors affecting supply and demand or may incorrectly interpret the information they do have. Furthermore, prices may often be affected by unrelated or unexpected factors and fundamental analysis may not enable the Trading Advisor to determine whether its previous decisions were incorrect in sufficient time to avoid substantial losses. In addition, fundamental analysis assumes that commodity markets are inefficient—i.e., that commodity prices do not always reflect all available information—which some market analysts dispute.

Increased competition from other systematic traders could reduce the Trading Advisors’ profitability.

There has been a dramatic increase over the past 15 to 25 years in the amount of assets managed pursuant to trading systems like those that some of the Trading Advisors may employ. This means increased trading competition among a larger number of market

participants for transactions at favorable prices, which could operate to the detriment of some or all Series by preventing the Trading Advisors from effecting transactions at the desired prices. It may become more difficult for the Trading Advisors to implement their trading strategies if other commodity trading advisors using technical systems are attempting to initiate or liquidate commodity interest positions at the same time as the Trading Advisors. The more competition there is for the same positions, the more costly and harder they will be to acquire.

Discretionary decision-making may result in missed opportunities or losses.

Because each of the Trading Advisors’ strategies involves some discretionary aspects in addition to analysis of technical factors, certain Trading Advisors may occasionally use discretion in investing the assets of a Series. 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’s 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 Series to avoid losses, and in fact, such use of discretion may cause the Series to forego profits which it may have otherwise earned had such discretion not been used.

The Trading Companies are subject to speculative position limits.

The U.S. futures exchanges have established speculative position limits (referred to as “position limits”) on the maximum net long or net short position which any person or group of persons may hold or control in particular futures and options on futures. Most exchanges also limit the amount of fluctuation in commodity futures contract prices on a single trading day. Therefore, a Trading Advisor may have to modify its trading instructions or reduce the size of its positions in one or more futures or options contracts in order to avoid exceeding such position limits, which could adversely affect the profitability of the Trading Companies. The futures exchange may amend or adjust these position limits or the interpretation of how such limits are applied, adversely affecting the profitability of the Trading Companies.

In addition, in October 2011, the CFTC adopted rules governing position limits on futures (and options on futures) on a number of agricultural, energy and metals commodities, as well as on swaps that perform a significant price discovery function with respect to those futures and options. In September 2012, the CFTC’s rules were vacated by the United States District Court for the District of Columbia and remanded to the CFTC for further consideration. The CFTC proposed revised position limits rules late in 2013. The comment period for the rules closed in February 2014, and the CFTC subsequently reopened comment periods for comments about certain issues related to futures and options contracts on agricultural commodities only. ThoseThese comment periods have also closed. The comment period for the rules has closed, and the date for the CFTC’s final rules is unknown. It is possible that these rules may take effect in some form. If so, these rules could have an adverse effect on the Trading Advisors’ trading for the Trading Companies.

Increases in assets under management of any of the Trading Advisors could lead to diminished returns.

We believe that none of the Trading Advisors intends to limit the amount of additional equity that it may manage, and each will continue to seek major new accounts. However, the rates of returns achieved by a Trading Advisor often diminish as the assets under its management increase. This can occur for many reasons, including the inability of the Trading Advisor to execute larger position sizes at desired prices and because of the need to adjust the Trading Advisor’s trading program to avoid exceeding speculative position limits. These limits are established by the CFTC and the exchanges on the number of speculative futures and options contracts in a commodity that one trader may own or control. Furthermore, if the Trading Advisors for a Series cannot manage any additional allocation from the Trust, the Managing Owner may add additional Trading Advisors for such Series who may have less experience or less favorable performance than the existing Trading Advisors.

The use of multiple Trading Advisors may result in offsetting or opposing trading positions and may also require one Trading Advisor to fund the margin requirements of another Trading Advisor.

The use of multiple Trading Advisors for the Equinox Frontier Diversified Fund, Equinox Frontier Masters Fund, Equinox Frontier Balanced Fund, Equinox Frontier Heritage Fund, Equinox Frontier Select Fund, and Equinox Frontier Long/Short Commodity Fund may result in developments or positions that adversely affect the respective Series’ NAV. For example, because the Trading Advisors trading for the Equinox Frontier Diversified Fund, Equinox Frontier Masters Fund, Equinox Frontier Balanced Fund, Equinox Frontier Heritage Fund, Equinox Frontier Select Fund, and Equinox Frontier Long/Short Commodity Fund will be acting independently, such Series could buy and sell the same futures contract, thereby incurring additional expenses but with no net change in its holdings. The Trading Advisors also may compete, from time to time, for the same trades or other transactions, increasing the cost to such Series of making trades or transactions or causing some of them to be foregone altogether. Even though the margin requirements resulting from each Trading Advisor’s trading for any such Series ordinarily will be met from that Trading Advisor’s allocated net assets of such Series, a Trading Advisor for the Equinox Frontier Diversified Fund, Equinox Frontier Masters Fund, Equinox Frontier Balanced Fund, Equinox Frontier Heritage Fund, Equinox Frontier Select Fund, or Equinox Frontier Long/Short Commodity Fund may incur losses of such magnitude that such Series is unable to meet margin calls from the allocated net assets of that Trading Advisor. If losses of such magnitude were to occur, the Clearing Brokers for the Trading Company or Trading Companies in which such Series invests its assets may require liquidations and contributions from the allocated net assets of another Trading Advisor for such Series.

The Trading Advisors’ trading programs bear some similarities and, therefore, may lessen the benefits to the Equinox Frontier Balanced Fund, Equinox Frontier Heritage Fund, Equinox Frontier Select Fund, Equinox Frontier Long/Short Commodity Fund, Equinox Frontier Diversified Fund and Equinox Frontier Masters Fund of having multiple Trading Advisors.

Each Trading Advisor has, over time, developed and modified the program it will use in trading. Nevertheless, the Trading Advisors’ trading programs have some similarities. These similarities may, in fact, mitigate the positive effect of having multiple Trading Advisors for the Equinox Frontier Diversified Fund, Equinox Frontier Masters Fund, Equinox Frontier Balanced Fund, Equinox Frontier Heritage Fund, Equinox Frontier Select Fund and Equinox Frontier Long/Short Commodity Fund. For example, in periods where one Trading Advisor experiences a draw-down, it is possible that these similarities will cause the other Trading Advisors to also experience a draw-down.

Each Series relies on its Trading Advisor(s) for success, and if a Trading Advisor’s trading is unsuccessful, the Series may incur losses.

The Trading Advisor(s) for each Series will make the commodity trading decisions for that Series. Therefore, the success of each Series depends on the judgment and ability of the Trading Advisors. A Trading Advisor’s trading for any Series may not prove successful under all or any market conditions. If a Trading Advisor’s trading is unsuccessful, the applicable Series may incur losses. Similarly, the success of each Series that invests in swaps largely depends on the judgment and ability of the commodity trading advisors whose trading programs are referenced by swaps in which such Series invests.

There are disadvantages associatedAre Disadvantages Associated with terminatingTerminating or replacingReplacing Trading Advisors.Advisors, Trading Programs or Reference Trading Programs.

A Trading Advisortrading advisor generally is required to recoup previous trading losses in its trading program or a reference trading program, as applicable, before it can earn performance-based compensation. However, the Managing Ownermanaging owner may elect to replace a Trading Advisortrading advisor, or any trading program or reference trading program, that has a “loss carryforward.” In that case, the Trusttrust would lose the “free ride” of any potential recoupment of the prior losses of such Trading Advisor.trading advisor, trading program or reference trading program. In addition, the new Trading Advisortrading advisor, trading program or reference trading program, or an existing trading advisor in respect of a new trading program or reference program, would earn the same type of performance-based compensation on the first dollars of investment profits.

It is also possible that (i) the advisory agreement with any Trading Advisor,trading advisor, once it expires, will not be renewed on the same terms as the current advisory agreement for that Trading Advisor,trading advisor, (ii) if assets of any Seriesseries allocated to a particular Trading Advisortrading advisor, trading program or reference trading program are reallocated to a new or different Trading Advisor,trading advisor, trading program or reference trading program, the new or different Trading Advisortrading advisor, with respect to its applicable trading program or reference trading program, will not manage the assets on terms as favorable to the Seriesseries as those previously negotiated, with the previous Trading Advisor, (iii) the addition of a new Trading Advisortrading advisor, trading program or reference trading program and/or the removal of one of the current Trading Advisorstrading advisors, trading programs or reference trading programs may cause disruptions in trading as assets are reallocated, or (iv) the services of a replacement trading advisor, in respect of a trading program, reference program or otherwise, may not be available. There is severe competition for the services of qualified trading advisors, and the Managing Ownermanaging owner may not be able to retain replacement or additional trading advisors on acceptable terms. The effect of the replacement of, or the reallocation of assets away from, a Trading Advisortrading advisor, trading program or reference trading program therefore could be significant.

Each Trading Advisor advises other clients and may achieve more favorable results for its other accounts.

Each of the Trading Advisors currently manages other trading accounts, and each will remain free to manage additional accounts, including its own accounts, in the future. A Trading Advisor may vary the trading strategies applicable to the Series for which it trades from those used for its other managed accounts, or its other managed accounts may impose a different cost structure than that of the Series for which it trades. Consequently, the results any Trading Advisor achieves for the Series for which it trades may not be similar to those achieved for other accounts managed by the Trading Advisor or its affiliates at the same time. Moreover, it is possible that those other accounts managed by the Trading Advisor or its affiliates may compete with the Series for which it trades for the same or similar positions in the commodity interest markets and that those other accounts may make trades at better prices than the Series for which it trades.

A Trading Advisor may also have a financial incentive to favor other accounts because the compensation received from those other accounts exceeds, or may in the future exceed, the compensation that it receives from managing the account of the Series for which it trades. Because records with respect to other accounts are not accessible to investors in the Units, investors will not be able to determine if any Trading Advisor is favoring other accounts.

The Trading Advisors’ positions may be concentrated from time to time, which may render each Series susceptible to larger losses than if the positions were more diversified.

One or more of the Trading Advisors may from time to time cause a Series to hold a few, relatively large positions in relation to its assets. Consequently, a loss in any such position could result in a proportionately greater loss to such Series than if the Series’ assets had been spread among a wider number of instruments.

Markets or positions may be correlated and may expose a Series to significant risk of loss.

Different markets traded or individual positions held by a Series of Units may be highly correlated to one another at times. Accordingly, a significant change in one such market or position may affect other such markets or positions. The Trading Advisors

cannot always predict correlation. Correlation may expose such Series of Units both to significant risk of loss and significant potential for profit.

Turnover in each Series’ portfolio may be high which could result in higher brokerage commissions and transaction fees and expenses.

Each Trading Advisor will make certain trading decisions on the basis of short-term market considerations. The portfolio turnover rate may be substantial at times, either due to such decisions or to market conditions, and this could result in one or more Series incurring substantial brokerage commissions and other transaction fees and expenses.

Stop-loss Orders May Not Prevent Large Losses.

Certain of the Trading Advisors may use stop-loss orders. Such stop-loss orders may not effectively prevent substantial losses, and depending on market factors at the time, may not be able to be executed at such stop-loss levels. No risk control technique can assure that large losses will be avoided.

Trading Swaps Creates Distinctive Risks.

The series may trade in certain swaps. Unlike futures and options on futures contracts, most swap contracts currently are not traded on or cleared by an exchange or clearinghouse. The CFTC currently requires only a limited class of swap contracts (certain interest rate and credit default swaps) to be cleared and executed on an exchange or other organized trading platform. In accordance with the Dodd-Frank Act, the CFTC will determine in the future which other classes of swap contracts will be required to be cleared and executed on an exchange or other organized trading platform. Until such time as these transactions are cleared, the series will be subject to a greater risk of counterparty default on its swaps. Because swaps do not generally involve the delivery of underlying assets or principal, the amount payable upon default and early termination is usually calculated by reference to the current market value of the contract. Swap dealers and major swap participants require the series to deposit initial margin and variation margin as collateral to support such series’ obligation under the swap agreement but may not themselves provide collateral for the benefit of any series. If the counterparty to such a swap defaults, the series would be a general unsecured creditor for any termination amounts owed by the counterparty to the series as well as for any collateral deposits in excess of the amounts owed by the series to the counterparty, which would result in losses to the series.

There are no limitations on daily price movements in swaps. Speculative position limits are not currently applicable to swaps, but in the future may be applicable for swaps on certain commodities. In addition, participants in the swap markets are not required to make continuous markets in the swaps they trade, and determining a market value for calculation of termination amounts can lead to uncertain results.

Trading of swaps has been and will continue to be subject to substantial change under the Dodd-Frank Act and related regulatory action. Under the Dodd-Frank Act, many commodity swaps will be required to be cleared through central clearing parties and executed on exchanges or other organized trading platforms. Security-based swaps will be subject to similar requirements. Additional regulatory requirements will apply to all swaps, whether subject to mandatory clearing or not. These include margin, collateral and capital requirements, reporting obligations, speculative position limits for certain swaps, and other regulatory requirements. Swaps which are not offered for clearing by a clearinghouse will continue to be traded bi-laterally. Such bi-lateral transactions will remain subject to many of the risks discussed in the preceding paragraphs.

Swap counterparties may hold collateral in U.S. or non-U.S. depositories. Non-U.S. depositories are not subject to U.S. regulation. The series’ assets held in these depositories are subject to the risk that events could occur which would hinder or prevent the availability of these funds for distribution to customers, including the series. Such events may include actions by the government of the jurisdiction in which the depository is located including expropriation, taxation, moratoria and political or diplomatic events.

The Unregulated Nature of Uncleared Trades in the OTC Markets Creates Counterparty Risks that Do Not Exist in Futures Trading on Exchanges or in Cleared Swaps.

Unlike futures contracts and cleared swaps, uncleared trades, such as forward contracts, some swaps and some OTC “spot” contracts, are entered into between private parties off an exchange or other trading platform and are not subject to clearing. As a result, the performance of those contracts is not guaranteed by an exchange or its clearinghouse and the series is at risk with respect to the ability of the counterparty to perform on the contract, including the creditworthiness of the counterparty. Trading of foreign exchange spot contracts of foreign exchange forwards and foreign exchange swaps (as such terms are defined in the Dodd-Frank Act), and of uncleared swaps is not regulated or is subject to limited regulation; therefore, there are limited or no specific standards or regulatory supervision of trade pricing and other trading activities that occur in those markets.

Foreign Currency and Spot Contracts Historically Were Not Regulated When Traded Between Certain “Eligible Contract Participants” and Are Subject to Credit Risk.

Each series may trade forward contracts in foreign currencies and may engage in spot commodity transactions (transactions in physical commodities). These contracts, unlike futures contracts and options on futures, historically were not regulated by the CFTC when traded between certain “eligible contract participants,” as defined in the Commodity Exchange Act. On July 21, 2010, the President signed into law major financial services reform legislation in the form of the Dodd-Frank Act. The Dodd-Frank Act includes foreign currency forwards and foreign currency swaps (as such terms are defined in the Dodd-Frank Act) in the definition of “swap.” The CFTC has been granted authority to regulate all swaps, but grants the U.S. Treasury Department the discretion to exempt foreign currency forwards and foreign currency swaps from all aspects of the Dodd-Frank Act other than reporting, recordkeeping and business conduct rules for swap dealers and major swap participants. In November 2012, Treasury determined that those transactions can be carved out of the swap category, and they are subject only to the noted categories of the Dodd-Frank Act requirements. Therefore, the series will not receive the full benefit of CFTC regulation for certain of their foreign currency trading activities.

The percentage of each Series’ positions that are expected to constitute foreign currency forwards and foreign currency swaps can vary substantially from month to month.

Trading on Foreign Exchanges Presents Greater Risks to the Series than Trading on U.S. Exchanges.

Each series trades on exchanges located outside the United States. Trading on U.S. exchanges is subject to CFTC regulation and oversight, including, for example, minimum capital requirements for commodity brokers, segregation of customer funds, regulation of trading practices on the exchanges, prohibitions against trading ahead of customer orders, prohibitions against filling orders off exchanges, prescribed risk disclosure statements, testing and licensing of industry sales personnel and other industry professionals, and recordkeeping requirements, and other requirements and restrictions for the purpose of preventing price manipulation and other disruptions to market integrity, avoiding systemic risk, preventing fraud and promoting innovation, competition and financial integrity of transactions. Trading on foreign exchanges is not regulated by the CFTC or any other U.S. governmental agency or instrumentality and may be subject to regulations that are different from those to which U.S. exchange trading is subject, provide less protection to investors than trading on U.S. exchanges, and may be less vigorously enforced than regulations in the U.S. The CFTC has no power to compel the enforcement of the rules of a foreign exchange or applicable foreign laws. Therefore, the series will not receive any benefit of U.S. government regulation for these trading activities.

Trading on foreign exchanges involves some risks that trading on U.S. exchanges does not, such as:

Lack of Investor Protection Regulation

The rights of the series in the event of the insolvency or bankruptcy of a non-U.S. market or broker are likely to differ from rights that the series would have in the United States and these rights may be more limited than in the case of failures of U.S. markets or brokers.

Possible Governmental Intervention

Generally, foreign brokers are not subject to the jurisdiction of the CFTC or any other U.S. regulator. In addition, the series’ assets held outside of the United States to margin transactions on foreign exchanges are held in accordance with the client assets protection regime and the insolvency laws of the applicable jurisdiction. A foreign government might halt trading in a market and/or take possession of the series’ assets maintained in its country in which case the assets may never be recovered. The managing owner and the series might have little or no notice that such events were happening. In such circumstances, the managing owner may not be able to obtain the series’ assets.

Relatively New Markets

Some foreign exchanges on which the series trade may be in developmental stages so that prior price histories may not be indicative of current price patterns.

Exchange-Rate Exposure

The series are valued in U.S. dollars. Contracts on foreign exchanges are usually traded in the local currency. The series’ assets held in connection with contracts priced and settled in a foreign currency may be held in a foreign depository in accounts denominated in a foreign currency. Changes in the value of the local currency relative to the U.S. dollar could cause losses to the series even if the contract traded is profitable.

Investments in Reference Programs Through a Swap or Other Derivative Instrument May Not Always Replicate Exactly Performance of the Relevant CTA Trading Program(s).

Certain Series invest in reference programs through total return swaps with Deutsche Bank AG. Such swaps reference an index comprised of shares in segregated investment portfolios directed by CTAs selected by the managing owner. It is possible that the underlying index in respect of any swap owned by a series may not fully replicate the performance of the relevant CTA programs in respect of other accounts traded by such CTAs. Further, the calculation of the underlying index for such swaps will include a deduction for a fee payable to the swap counterparty. Each of these deductions will mean that the return of such investment will be less than would be the case if no fees were deducted.

There Are Certain Risks Associated with the Trust’s Investment in U.S. Government Debt Securities.

With respect to the portion of the Trust’s assets apportioned for cash management, the Trust may invest in U.S. government securities which include any security issued or guaranteed as to principal or interest by the United States, or by a person controlled by or supervised by and acting as an instrumentality of the government of the United States pursuant to authority granted by Congress of the United States 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 (such as Ginnie Mae, Fannie Mae, or Freddie Mac). U.S. government securities are subject to market risk, interest rate risk and credit risk. Securities, such as those issued or guaranteed by Ginnie Mae or the U.S. Treasury, that are backed by the full faith and credit of the United States are guaranteed only as to the timely payment of interest and principal when held to maturity and the market prices for such securities will fluctuate. Notwithstanding that these securities are backed by the full faith and credit of the United States, circumstances could arise that would prevent the payment of interest or principal. This would result in losses to the Trust. Securities issued or guaranteed by U.S. government-related organizations, such as Fannie Mae and Freddie Mac, are not backed by the full faith and credit of the U.S. government and no assurance can be given that the U.S. government would provide financial support. Therefore, U.S. government-related organizations may not have the funds to meet their payment obligations in the future.

The Trust’s Investment in U.S. Government Debt Securities Will Be Subject to Interest Rate Risk.

The Trust’s cash management pool includes investments in U.S. government debt securities that change in value based on changes in interest rates. If rates increase, the value of these investments generally declines. On the other hand, if rates fall, the value of these investments generally increases. U.S. government securities with greater interest rate sensitivity and longer maturities tend to produce higher yields, but are subject to greater fluctuations in value. Usually, the changes in the value of fixed income securities will not affect cash income generated, but may affect the value of your investment. Given the current low interest rate environment, the risk associated with rising rates is heightened.

Operating Risks

Past performance is not necessarily indicative of future performance.

The Managing Owner has selected each Trading Advisor to manage the assets of each Series because each Trading Advisor performed well through the date of its selection. You must consider, however, the uncertain significance of past performance, and you should not rely to a substantial degree on the Trading Advisors’ or the Managing Owner’s records to date for predictive purposes. You should not assume that any Trading Advisor’s future trading decisions will create profit, avoid substantial losses or result in performance for the Series comparable to that Trading Advisor’s or to the Managing Owner’s past performance. In fact, as a significant amount of academic study has shown, futures funds more frequently than not under-perform the past performance records included in their prospectuses. The managing owner believes that the past performance of the trading advisors may be of interest to prospective investors, but encourages you to look at such information as an example of the respective objectives of the managing owner and each trading advisor rather than as any indication that the investment objectives of any series will be achieved.

Because you and other investors will acquire, exchange and redeem Units at different times, you may experience a loss on your Units even though the Series in which you have invested as a whole is profitable and even though other investors in that Series experience a profit. The past performance of any Series may not be representative of each investor’s investment experience in it.

Likewise, you and other investors will invest in different Series managed by different Trading Advisors. Each Series’ assets are valued and accounted for separately from every other Series. Consequently, the past performance of one Series has no bearing on the past performance of another Series. You cannot, for example, consider the Equinox Frontier Balanced Fund’s past performance in deciding whether to invest in any other Series.

You have limited performance information on which to evaluate an investment in a Series.

Certain of the Series have limited performance histories upon which to evaluate your investment in such Series. Although past performance is not necessarily indicative of future results, if any such Series had a longer performance history, such performance history might provide you with more information on which to base your investment decision for such Series. As such Series have limited performance histories, you will have to make your decision to invest in any such Series without such possibly useful information.

The Managing Owner may allocate nominal assets in respect of a Series that are in excess of the NAV of such Series.

At any given time, the nominal assets, which are the total amount of assets of a series allocated to trading advisors and/or reference programs, including (i) actual funds deposited in accounts directed by the trading advisors or deposited as margin in respect of swaps or other derivative instruments referencing a reference program plus (ii) any notional equity allocated to the trading advisors and any reference programs, of a Series may exceed the NAV of such Series depending on the amount of notional equity that is being utilized. The Managing Owner expects that the nominal assets of each Series will generally be maintained at a level in excess of the NAV of such Series and such excess may be substantial to the extent the Managing Owner deems necessary to achieve the desired level of volatility. To the extent that nominal assets of a Series are in excess of NAV, investors should understand that the applicable Series will experience greater volatility as measured by NAV than it would if the nominal assets were maintained at a level equal to NAV. In such case, any losses to the Series will be greater as measured by a percentage of NAV, as compared to the percentage loss incurred in respect of nominal assets. Consequently, the allocation of nominal assets in excess of a Series’ NAV will magnify exposure to the swings in market prices of futures, forwards, options or other assets held by a trading company or referenced by a swap or other derivative instrument and result in increased volatility, and potentially greater losses. You may lose all or substantially all of your investment in a Series.

Each Series is charged substantial fees and expenses regardless of profitability.

Each Series is charged brokerage charges, over-the-counter (or OTC) dealer spreads and related transaction fees and expenses and management fees in all cases regardless of whether any Series’ activities are profitable. In addition, the Managing Owner charges each Series an incentive fee based on a percentage of the trading profits generated by each trading advisor for such Series, and the Managing Owner pays all or a portion of such incentive fees to the Trading Advisor(s) for such Series. Because the Equinox Frontier Balanced Fund, Equinox Frontier Heritage Fund, Equinox Frontier Select Fund, Equinox Frontier Diversified Fund, Equinox Frontier Masters Fund and Equinox Frontier Long/Short Commodity Fund may each employ multiple Trading Advisors, it is possible that such Series could pay substantial incentive fees out of the net assets of any such Series with respect to one or more Trading Advisors in a year in which such Series has no net trading profits or in which such Series actually loses money. In addition, each Series must earn trading profits and interest income sufficient to cover these fees and expenses in order for it to be profitable.

Investors should note that the management fee payable to the Managing Owner is based on nominal assets rather than NAV. Therefore, the management fee will be greater as a percentage of a Series’ NAV to the extent that the nominal assets of such Series exceed its NAV. The Managing Owner expects that the nominal assets of each Series will generally be maintained at a level in excess of the net asset value for such Series and such excess may be substantial to the extent the Managing Owner deems necessary to achieve the desired level of volatility.

There are certain risks associated with investments in trading companies.

Certain of the trading companies may be organized as series limited liability companies. This means that, under the Delaware Limited Liability Company Act, the assets of one Series are not available to pay the liabilities of another Series or the trading company as a whole. This statute has not been tested in a court of law in the United States. In the event series limited liability is not enforceable, a segregated Series could be obligated to pay the liabilities of another Series or the trading company. 

Each of the Series except for Equinox Frontier Winton Fund invests in trading companies that, although they are organized as series limited liability companies, allocate assets to more than one commodity trading advisor without the establishment of separate series with segregated liabilities. For these trading companies, losses incurred by one commodity trading advisor may negatively impact the trading company as a whole, as the assets allocated to a different commodity trading advisor may be made available to pay the liabilities of the commodity trading advisor that has incurred the loss. Since the Series currently invest in such trading companies, this could indirectly cause the assets of one Series to be used to pay the liabilities of another Series. For trading companies that allocate assets to more than one commodity trading advisor, a Series may be allowed to allocate a portion of its assets to a particular commodity trading advisor accessed by the trading company, rather than to the trading company as a whole.

Differing levels of fees received may create an incentive for the Managing Owner to favor certain Series over others.

The Managing Owner charges the various Series differing levels of fees. This may create an incentive for the Managing Owner to favor certain Series over other Series in, among other things, the amount of time and effort spent managing any given Series and the selection of Trading Advisors for a given Series.

Each Series may incur higher fees and expenses upon renewing existing or entering into new contractual relationships.

The clearing agreements between the Clearing Brokers and the Trading Companies generally are terminable by the Clearing Brokers once the Clearing Broker has given the Trading Company the required notice. Upon termination of a clearing agreement, the Managing Owner may be required to renegotiate that agreement or make other arrangements for obtaining clearing. The services of the Clearing Brokers may not be available, or even if available, these services may not be available on the terms as favorable as those contained in the expired or terminated clearing agreements.

The Series may be obligated to make payments under guarantee agreements.

Each of the Series has guaranteed the obligations of the trading companies under the customer agreements with UBS Securities as Clearing Broker. In the event that one Series is unable to meet its obligations to UBS Securities, the assets of the other Series will be available to UBS Securities as part of the guarantee, but only to the extent of such Series’ pro rata allocation to the trading company. As such, even if you are not invested in the defaulting Series, your investment could be impacted. The Trust, or any Series of the Trust, may enter into similar guarantees in the future.

The incentive fees could be an incentive to the Trading Advisors to make riskier investments.

The Managing Owner pays each Trading Advisor incentive fees based on the trading profits earned by it for the applicable Series, including unrealized appreciation on open positions. Accordingly, it is possible that the Managing Owner will pay an incentive fee on trading profits that do not become realized. Also, because the Trading Advisors are compensated based on the trading profits earned, each of the Trading Advisors has a financial incentive to make investments that are riskier than might be made if a Series’ assets were managed by a Trading Advisor that did not receive performance-based compensation.

You have limited rights, and you cannot prevent the Trust from taking actions which could cause losses.

You will exercise no control over the Trust’s day-to-day business. Therefore, the Trust will take certain actions and enter into certain transactions or agreements without your approval. For example, the Trust may retain a Trading Advisor for a Series in which you are invested, and such Trading Advisor may ultimately incur losses for the Series. As a Limited Owner, you will have no ability to influence the hiring, retention or firing of such Trading Advisor. However, certain actions, such as termination or dissolution of a Series, may only be taken upon the affirmative vote of Limited Owners holding Units representing at least a majority (over 50%) of the NAV of the Series (excluding Units owned by the Managing Owner and its affiliates).

You may not be able to establish a basis for liability against a Trading Advisor, a Clearing Broker or the Swap Counterparty.

Each Trading Advisor, Clearing Broker and Swap counterparty acts only as a trading advisor, clearing broker or swap counterparty, respectively, to the applicable Series and/or Trading Company. These parties do not act as trading advisors, clearing brokers, or swap counterparties to you. Therefore, you have no contractual privity with the Trading Advisors, the Clearing Brokers or any Swap counterparty. Due to this lack of contractual privity, you may not be able to establish a basis for liability against a Trading Advisor, Clearing Broker or Swap counterparty.

An unanticipated number of redemption requests over a short period of time could result in losses.

Substantial redemptions of units could require a Series to liquidate investments more rapidly than otherwise desirable in order to raise the necessary cash to fund the redemptions, which could result in losses. Illiquidity in the markets could make it difficult to liquidate positions on favorable terms, which could result in additional losses. It may also be difficult for the Series to achieve a market position appropriately reflecting a smaller equity base.

Reserves for contingent liabilities may be established upon redemption, and the Trust may withhold a portion of your redemption amount.

When you redeem your units, the Trust may find it necessary to set up a reserve for undetermined or contingent liabilities and withhold a certain portion of your redemption amount. This could occur, for example, if (i) some of the positions of the Series in which you were invested were illiquid, (ii) there are any assets which cannot be properly valued on the redemption date, or (iii) there is any pending transaction or claim by or against the Trust involving or which may affect your capital account or your obligations.

Conflicts of interest exist in the structure and operation of the Trust.

A number of actual and potential conflicts of interest exist in the operation of the Trust’s business. The Managing Owner, the Trading Advisors and their respective principals are all engaged in other investment activities, and are not required to devote substantially all of their time to the Trust’s business.

The failure or bankruptcy of one of its Futures Clearing Brokers, central clearing brokers, banks, counterparties or other custodians could result in a substantial loss of one or more Series’ assets.

The Trust is subject to the risk of insolvency of an exchange, clearinghouse, central clearing broker, commodity broker, and counterparties with whom the trading companies trade. Trust assets could be lost or impounded in such an insolvency during lengthy bankruptcy proceedings. Were a substantial portion of the Trust’s capital tied up in a bankruptcy, the Managing Owner might suspend or limit trading, perhaps causing a Series to miss significant profit opportunities. The Trust is subject to the risk of the inability or refusal to perform on the part of the counterparties with whom contracts are traded. In the event that the Clearing Brokers are unable to perform their obligations, the Trust’s assets are at risk and investors may only recover apro ratashare of their investment, or nothing at all.

Exchange-traded futures and futures-styled option contracts are marked to market on a daily basis, with variations in value credited or charged to the Trust’s account on a daily basis. The Clearing Brokers, as futures commission merchants for the Trust’s exchange-traded contracts, are required, pursuant to CFTC regulations, to segregate from their own assets, and for the sole benefit of their commodity customers, all funds held by such clients with respect to exchange-traded futures and futures-styled options contracts, including an amount equal to the net unrealized gain on all open futures and futures-styled options contracts. Similar requirements apply with respect to funds held in connection with cleared swap contracts. Bankruptcy law applicable to all U.S. futures brokers requires that, in the event of the bankruptcy of such a broker, all property held by the broker, including certain property specifically traceable to the Trust, will be returned, transferred, or distributed to the broker’s customers only to the extent of each customer’spro rata share of the assets held by such futures broker. The Managing Owner will attempt to limit the Trust’s deposits and transactions to well-capitalized institutions in an effort to mitigate such risks, but there can be no assurance that even a well-capitalized, major institution will not become bankrupt.

In the event of a shortfall in segregated customer funds held by the futures commission merchant, the series’ assets on account with the futures commission merchant may be at risk in the event of the futures commission merchant’s bankruptcy or insolvency, and in such event, the series may only recover a portion of the available customer funds. If no property is available for distribution, the series would not recover any of its assets. With respect to a series’ OTC uncleared swaps, prior to the implementation of the Dodd-Frank Act’sAct��s provisions, there was no requirement to segregate funds held with respect to such contracts. There is still no requirement to segregate funds held as variationOn December 16, 2015, the CFTC finalized rules regarding margin posted by a party engagingfor uncleared swaps which will impose certain requirements beginning September 1, 2016. These rules require, among other things, daily two-way margin (posting and collecting) for all trades between covered swap entities (“CSEs”) and swap dealers (“SDs”) and major swap participants (“MSPs”), and daily two-way margin for all trades between CSEs and financial end users that have over $8 billion in gross notional exposure in uncleared swaps with a swap dealer or major swap participant; however, a party engaging in uncleared swaps with a swap dealer or major swap participant can ask that the initial margin posted by such party be held with an independent third party custodian. Generally, the party requesting segregation will pay the costs of such custodial arrangement.swaps. The rules also require daily cash payments for all trades between CSEs and SD/MSPs and daily posting for all trades between SD/MSPs and financial end users. There may also be costs and delays involved in negotiating the custodial arrangement and related contractual terms.

With respect to transactions a Series enters into that are not traded on an exchange, there are no daily settlements of variations in value and there is no requirement to segregate funds held with respect to such accounts. Thus, the funds that a Series invests in such transactions may not have the same protections as funds used as margin or to guarantee exchange-traded futures and options contracts. If the counterparty becomes insolvent and a Series has a claim for amounts deposited or profits earned on transactions with the counterparty, the Series’ claim may not receive a priority. Without a priority, the Trust is a general creditor and its claim will be paid, along with the claims of other general creditors, from any monies still available after priority claims are paid. Even funds of the Trust that the counterparty keeps separate from its own operating funds may not be safe from the claims of other general and priority creditors. There are no limitations on the amount of allocated assets a portfolio manager can trade on foreign exchanges or in forward contracts.

You will not be able to review any Series’ holdings on a daily basis, and you may suffer unanticipated losses.

The Trading Advisors make trading decisions on behalf of the assets of each Series. While the Trading Advisors receive daily trade confirmations from the Clearing Brokers of each transaction entered into on behalf of each Series for which they manage the trading, each Series’ trading results are only reported to investors monthly in summary fashion. Accordingly, an investment in the Units does not offer investors the same transparency that a personal trading account offers. As a result, you may suffer unanticipated losses.

You Will Not Be Aware of Changes to Trading Programs.

Because of the proprietary nature of each Trading Advisor’s trading programs, you generally will not be advised if adjustments are made to a trading program in order to accommodate additional assets under management or for any other reason.

The Trust could terminate before you achieve your investment objective causing potential loss of your investment or upsetting your investment portfolio.

Unforeseen circumstances, including substantial losses or withdrawal of the Trust’s Managing Owner, could cause the Trust to terminate before its stated termination date of December 31, 2053. The Trust’s termination would cause the liquidation and potential loss of your investment and could upset the overall maturity and timing of your investment portfolio.

Neither the Trust nor any of the trading companies is a registered investment company.

Neither the Trust nor any of the trading companies is an investment company subject to the Investment Company Act. Accordingly, you do not have the protections afforded by that statute. For example, the Investment Company Act requires investment companies to have a majority of disinterested directors and regulates the relationship between the investment company and its investment adviser. Since neither the Trust nor the trading companies is a registered investment company, you will not benefit from such protections.

The Managing Owner is leanly staffed and relies heavily on its key personnel to manage the Trust’s trading activities. The loss of such personnel could adversely affect the Trust.

In managing and directing the day-to-day activities and affairs of the Trust, the Managing Owner relies heavily on its principals. The Managing Owner is leanly staffed, although there are back-up personnel for every key function. If any of its key persons were to leave or be unable to carry out his or her present responsibilities, it may have an adverse effect on the management of the Trust.

In addition, under the operating agreement of the Managing Owner, Mr. Bornhoft’s ability to serve as the Chief Investment Officer of the Managing Owner is dependent upon certain factors. If Mr. Bornhoft ceases to be the Chief Investment Officer of the Managing Owner, the Trust may be adversely affected.

The Managing Owner places significant reliance on the Trading Advisors and their key personnel; the loss of such personnel could adversely affect a Series.

The Managing Owner relies on the Trading Advisors to achieve trading gains for each Series, entrusting each of them with the responsibility for, and discretion over, the investment of their allocated portions of the Trust’s assets. The Trading Advisors, in turn, are dependent on the services of a limited number of persons to develop and refine their trading approaches and strategies and execute the trading transactions. The loss of the services of any Trading Advisor’s principals or key employees, or the failure of those principals or key employees to function effectively as a team, may have an adverse effect on that Trading Advisor’s ability to manage its trading activities successfully or may cause the Trading Advisor to cease operations entirely. This, in turn, could negatively impact one or more Series’ performance. Each of the Trading Advisors is wholly- (or majority-) owned and controlled, directly or indirectly, by single individuals who have major roles in developing, refining and implementing the Trading Advisor’s trading strategies and operating its business. The death, incapacity or other prolonged unavailability of such individuals likely would greatly hinder these Trading Advisors’ operations, and could result in their ceasing operations entirely, which could adversely affect the value of your investment.

The Managing Owner may terminate, replace and/or add Trading Advisors in its sole discretion which may disrupt trading, adversely affecting the Net Asset Value of a Series.

The Managing Owner may terminate, substitute or retain Trading Advisors on behalf of each Series in its sole discretion. The addition of a new Trading Advisor and/or the removal of one of the current Trading Advisors may cause disruptions in trading as assets are reallocated and new Trading Advisors transition over, which may have an adverse effect on the NAV of the affected Series.

The Managing Owner’s allocation of the Trust’s assets among Trading Advisors may result in less than optimal performance by the Trust.

The Managing Owner may reallocate assets among the Trading Advisors for the Equinox Frontier Diversified Fund, Equinox Frontier Masters Fund, Equinox Frontier Balanced Fund, Equinox Frontier Heritage Fund, Equinox Frontier Select Fund or Equinox Frontier Long/Short Commodity Fund upon termination of a Trading Advisor or retention of a new Trading Advisor or at the commencement of any month. Consequently, the net assets for such Series may be allocated among the Trading Advisors in a different manner than the currently anticipated allocations. The Managing Owner’s allocation of assets of any such Series may adversely affect the profitability of the trading of the Equinox Frontier Diversified Fund, Equinox Frontier Masters Fund, Equinox Frontier Balanced Fund, Equinox Frontier Heritage Fund, Equinox Frontier Select Fund and Equinox Frontier Long/Short Commodity Fund, possibly in an adverse manner. For example, a Trading Advisor for a Series may experience a high rate of return but may be managing only a small percentage of the net assets of such Series. In this case, the Trading Advisor’s performance could have a minimal effect on the NAV of such Series.

The success of each Series depends on the ability of the personnel of its Trading Advisor(s) to accurately implement their trading systems, and any failure to do so could subject a Series to losses.

The Trading Advisors’ computerized trading systems rely on the Trading Advisors’ personnel to accurately process the systems’ outputs and execute the transactions called for by the systems. In addition, each Trading Advisor relies on its staff to properly operate and maintain the computer and communications systems upon which its trading systems rely. Execution and operation of each Trading Advisor’s systems is therefore subject to human errors. Any failure, inaccuracy or delay in implementing any of the Trading Advisors’ systems and executing transactions could impair the trading advisor’s ability to identify profit opportunities and benefit from them. It could also result in decisions to undertake transactions based on inaccurate or incomplete information. This could cause substantial losses.

Regulation of the commodity interest markets is extensive and constantly changing; future regulatory developments are impossible to predict and may significantly, but adversely affect the Trust.

The futures, options on futures and security futures markets are subject to comprehensive statutes, regulations and margin requirements. With respect to traditional futures exchanges, the CFTC and the exchanges are authorized to take extraordinary actions in the event of a market emergency, including, for example, the retroactive implementation of speculative position limits or higher margin requirements, the establishment of daily limits and the suspension of trading. The regulation of commodity interest transactions in the United States is a rapidly changing area of law and is subject to ongoing modification by governmental and judicial action. In addition, various national governments have expressed concern regarding the disruptive effects of speculative trading in the currency markets and the need to regulate the derivatives markets in general. The effect of any future regulatory change is impossible to predict, but could be substantial and adverse.

The Risk Management Approaches of One or All of the Trading Advisors May Not Be Fully Effective, and a Series May Incur Losses.

The mechanisms employed by each Trading Advisor to monitor and manage the risks associated with its trading activities on behalf of the Series for which it trades may not succeed in mitigating all identified risks. Even if a Trading Advisor’s risk management approaches are fully effective, it cannot anticipate all risks that it may face. If one or more of the Trading Advisors fails to identify and adequately monitor and manage all of the risks associated with its trading activities, the Series for which it trades may suffer losses.

The Managing Owner May Adjust the Leverage Employed by a Trading Advisor to Maintain the Target Rate of Volatility.

In its sole discretion, the managing owner may modify the allocations between the trading advisors used by a particular series at any time, including adding new trading advisors or terminating current trading advisor relationships, and the managing owner may also increase or decrease the amount of leverage employed by a specific trading advisor by allocating notional funds to a particular trading advisor in accordance with the managing owner’s proprietary management program. The managing owner may increase or decrease the notional equity allocated to one or more individual trading advisors over time in order to adjust the annual volatility for a series within the target volatility range disclosed for such series.

To the extent that the managing owner increases the leverage employed by a particular trading advisor to maintain the target volatility of a series, either by increasing the actual funds which are traded by the trading advisor at a leverage of greater than 1x or by allocating notional amounts to one or more trading advisors, the specific risks associated with the relevant trading advisors will be greater for the affected series. As the notional equity under management of a specific trading advisor increases, the diversification benefits attributable to a multi-advisor pool will be decreased to an extent, since the trading advisor will manage a greater percentage of the notional exposure of the series. Since the managing owner may change the applicable leverage used by a particular trading advisor at any time, the diversification of risks between the trading advisors is variable.

Tax and ERISA Risks

You are strongly urged to consult your own tax advisor and counsel about the possible tax consequences to you of an investment in the Trust. Tax consequences may differ for different investors, and you could be affected by changes in the tax laws.

You May Have Tax Liability Attributable to Your Investment in a Series Even if You Have Received No Distributions and Redeemed No Units, and Even if the Series Generated an Economic Loss.

If a Series has profit for a taxable year (as determined for federal income tax purposes), the profit will be includible in your taxable income, whether or not cash or other property is actually distributed to you by the Series. The Managing Owner does not intend to make any distributions from any Series. Accordingly, it is anticipated that federal income taxes on your allocable share of a Series’ profits will exceed the amount of distributions to you, if any, for a taxable year. As such, you must be prepared to satisfy any tax liability from redemptions of Units or other sources. In addition, a Series may have capital losses from trading activities that cannot be deducted against the Series’ interest income, so that you may have to pay taxes on interest income even if the Series generates a net economic loss for a taxable year.

You may be taxed on gains that the Trust never realizes.

Because a substantial portion of the Trust’s open positions are “marked-to-market” at the end of each year, some of your tax liability for each year may be based on unrealized gains that the Trust may never actually realize.

Partnership treatment is not assured, and if the Trust is not treated as a Partnership, you could suffer adverse tax consequences.

The Managing Owner believes that the Trust and each Series will be treated as a partnership for Federal income tax purposes and, assuming that at least 90% of the gross income of the Trust, and each Series, has always constituted and will continue to constitute “qualifying income” within the meaning of Section 7704(d) of the Code, neither the Trust nor any Series will be treated as a publicly traded partnership treated as a corporation. The Managing Owner believes it is likely, but not certain, that the Trust, and each Series, will meet this income test. The Trust has not requested, and does not intend to request, a ruling from the Internal Revenue Service (the “IRS”), concerning its tax treatment or the tax treatment of any Series.

If the Trust, or any Series, were to be treated as a corporation for Federal income tax purposes: the net income of the Trust, or the Series, would be taxed at corporate income tax rates, thereby substantially reducing its distributable cash; you would not be allowed to deduct losses of the Trust, or a Series; and distributions to you, other than liquidating distributions, would constitute dividends to the extent of the current or accumulated earnings and profits of the Trust, or a Series, and would be taxable as such.

There is the possibility of a tax audit which could result in additional taxes to you.

The Trust’s tax returns may be audited by a taxing authority, and such an audit could result in adjustments to the Trust’s returns. If an audit results in an adjustment, you may be compelled to file amended returns and to pay additional taxes plus interest and penalties.

You will likely recognize short-term capital gain.

Profits on futures contracts traded in regulated U.S. and some foreign exchanges, foreign currency contracts traded in the interbank market, and U.S. and some foreign exchange-traded options on commodities are generally taxed as short-term capital gain to the extent of 40% of gains with respect to section 1256 contracts. Special rules apply in the case of mixed straddles (generally, offsetting positions where some, but not all, of the positions are marked-to-market). These special rules could have the effect of limiting the amount of gain treated as long-term capital gain.

The IRS could challenge allocations of recognized gains to Unitholders who redeem.

The trust agreement provides that recognized gains may be specially allocated for tax purposes to redeeming limited owners. If the IRS were to successfully challenge such allocations, each remaining limited owner’s share of recognized gains would be increased.

The IRS could take the position that deductions for certain Trust expenses are subject to various limitations.

Non-corporate taxpayers are subject to certain limitations for deductions for “investment advisory expenses” for federal income tax and alternative minimum tax purposes. The IRS could argue that certain expenses of the Trust are investment advisory expenses.

The investment of Benefit Plan Investors may be limited and/or Subject to Mandatory Redemption if any or all of the Series (or Class of any Series) are deemed to hold plan assets or if the Trading Advisors have fiduciary relationships with certain investing Benefit Plan Investors and Benefit Plan Investors are required to consider their fiduciary responsibilities in making an investment decision.

Special considerations apply to investments in the Trust by individual retirement accounts, pension, profit-sharing, stock bonus, Keogh, welfare benefit and other employee benefit plans whether or not subject to ERISA or Section 4975 of the Code, each a Plan, a Plan that is subject to Part 4 of Subtitle B of Title I of ERISA or Section 4975 of the Code, or an ERISA Plan, and any entity whose underlying assets include plan assets by reason of a Plan’s investment in such entity is referred to as a “Benefit Plan Investor.PlanInvestor.” While the assets of the Trust or any Series (and Class of any Series) are intended not to constitute plan assets with respect to any Benefit Plan Investors, the United States Department of Labor, or the DOL, IRS or a court could disagree. If the DOL, IRS or a court were to find that the assets of some or all of the Series (or Class of any Series) are the assets of Benefit Plan Investors, the Managing Owner and the Trading Advisors to such Series (or Class) may be fiduciaries, and certain transactions in or by the Trust could be prohibited. For example, if the Trust were deemed to hold “plan assets,” within the meaning of 29 C.F.R. § 2510.3-101, the Trading Advisors may have to refrain from directing certain transactions that are currently contemplated. Furthermore, whether or not the Trust is deemed to hold plan assets, if a Benefit Plan Investor has certain pre-existing relationships with the Managing Owner, one or more Trading Advisors, the selling agents or a Clearing Broker, investment in a Series may be limited or prohibited. In the event that, for any reason, the assets of any Series (or Class of any Series) might be deemed to be “plan assets,” and if any transactions would or might constitute prohibited transactions under ERISA or the Code and an exemption for such transaction or transactions is not available or cannot be obtained (or the Managing Owner determines not to seek such exemption), the Managing Owner reserves the right, upon notice to, but without the consent of any limited owner, to mandatorily redeem Units held by any limited owner that is a Benefit Plan Investor. Furthermore, whether or not a Series (or Class of any Series) are plan assets, Benefit Plan Investors should consider their fiduciary responsibilities before making a decision to invest in a Series (or Class of any Series) and Plan investors who are not subject to ERISA may be subject to similar responsibilities under state, local, or non-U.S. law.

Foreign investors may face exchange rate risk and local tax consequences.

Foreign investors should note that the Units are denominated in U.S. dollars and that changes in the rates of exchange between currencies may cause the value of their investment to decrease.

Regulatory Risks

Regulation of the Commodity Interest Markets is Extensive and Constantly Changing; Future Regulatory Developments are Impossible to Predict, but May Significantly and Adversely Affect the Trust.

The futures, options on futures and security futures markets are subject to comprehensive statutes, regulations and margin requirements. With respect to traditional futures exchanges, the CFTC and the exchanges are authorized to take extraordinary actions in the event of a market emergency, including, for example, the retroactive implementation of speculative position limits or higher margin requirements, the establishment of daily limits and the suspension of trading. The regulation of commodity interest transactions in the United States is a rapidly changing area of law and is subject to ongoing modification by governmental and judicial action. In addition, various national governments have expressed concern regarding the disruptive effects of speculative trading in the currency markets and the need to regulate the derivatives markets in general. The effect of any future regulatory change is impossible to predict, but could be substantial and adverse.

CFTC registrations could be terminated which could adversely affect the Trust or a Series.

If the Commodity Exchange Act registrations or NFA memberships of the Managing Owner or the registered Trading Advisors were no longer effective, these entities would not be able to act for the Trust, which could adversely affect the Trust or such Series.

The Trust and the Managing Owner have been represented by unified counsel, and neither the Trust nor the Managing Owner will retain independent counsel to review this offering.

The Trust and the Managing Owner have been represented by unified counsel. To the extent that the Trust, the Managing Owner or you could benefit from further independent review, such benefit will not be available unless you separately retain such independent counsel.

The foregoing risk factors are not a complete explanation of all the risks involved in purchasing interests in a fund that invests in the highly speculative, highly leveraged trading of futures, forwards and options. You should read this entire Form 10-K and the Prospectus before determining to subscribe for Units.

Item 1B.

UNRESOLVED STAFF COMMENTSUNRESOLVEDSTAFF COMMENTS..

None.

The Trust does not own or use any physical properties in the conduct of its business. Its assets currently consist of cash items such as custom time deposits, and, through each Trading Company, items such as U.S. and international futures and forward contracts and other interests in derivative instruments, including options contracts on futures, forwards and swap contracts. The Managing Owner’s main office is located at 1775 Sherman Street, Suite 2500, Denver, Colorado 80203.

This section describes the major pending legal proceedings, other than ordinary routine litigation incidental to the business, to which the Managing Owner or its subsidiaries is a party or to which any of their property is subject. There are no material legal proceedings to whichpending against the Trust or any Series.

On January 19, 2016, the Managing Owner consented to and became the subject of an Order Instituting Administrative and Cease-and-Desist Proceedings Pursuant to Section 8A of the Securities Act of 1933, Section 21C of the Securities Exchange Act of 1934, and Section 203(e) of the Investment Advisers Act of 1940, Making Findings, and Imposing Remedial Sanctions and a Cease-and-Desist Order by the SEC to resolve allegations related to certain disclosures of certain options invested in by certain of the Series of the Trust, as well as the Managing Owner’s calculation and disclosure of management fees paid by investors in certain of the Series. On or about March 16, 2016, the Managing Owner consented to and became the subject of an Order Instituting Proceedings Pursuant to
Sections 6(c) and 6(d) of the Commodity Exchange Act, Making Findings and Imposing Remedial Sanctions by the CFTC to resolve similar claims. Specifically, each of the SEC and CFTC found that the Trust’s disclosures regarding its affiliates ismethodology of valuing certain derivatives were misleading; that the Trust’s disclosure regarding the transfer of an option between Series was misleading; that the Trust failed to disclose a partymaterial subsequent event in the Trust’s Quarterly Report on Form 10-Q for the period ended June 30, 2011; and that the Managing Owner committed a disclosure violation related to how management fees were calculated and paid to the Managing Owner.

Without admitting or denying the underlying allegations and without adjudication of which any issue of their assets arelaw or fact, the subject.Managing Owner accepted and consented to entry of findings and the imposition of a cease and desist order, censure, payment of disgorgement and prejudgment interest, civil monetary penalties of $400,000 to the SEC and $250,000 to the CTFC, respectively, and undertakings related to public statements, cooperation and payment of the disgorgement, interest and fines.

Not applicable.

Part II

No Units in any Series are publicly traded. The Units in each Series may be redeemed, in whole or in part, on a daily basis, subject to a notice requirement as set forth in the Prospectus. Except as otherwise set forth in the Prospectus, Units will be redeemed at a redemption price equal to 100% of the NAV per Unit of the applicable Series, calculated as of the point described in the Prospectus. The redemption of Units has no impact on the value of Units that remain outstanding. The Managing Owner may temporarily suspend redemptions under limited circumstances described in the Prospectus. The right to obtain redemption of Units of a Series is contingent upon such Series’ having property sufficient to discharge its liabilities on the date of redemption.

Further, if a Limited Owner redeems all or a portion of its Class 1 or Classand 1a Units of any Series on or before the end of twelve full months following the effective date of the purchase of the Units being redeemed, such Limited Owner is charged a redemption fee of up to 3.0% of the NAV at which the Units are redeemed. The redemption fee charged will depend on, among other things, the particular Series of Units being redeemed. The Trust Agreement also contains restrictions on the transfer or assignment of the Units.

The Managing Owner has the sole discretion in determining what distributions, if any, the Trust will make to the Limited Owners. The Trust has not affected distributions on the Units in any Series as of the date hereof and the Managing Owner does not intend to effect any distributions in the foreseeable future.

The proceeds of offerings are deposited in the bank and brokerage accounts of the Trust and the Trading Companies for the purpose of engaging in trading activities in accordance with the Trust’s trading policies and its Trading Advisors’ respective trading strategies.

The following table shows the number of Limited Owners and the number of Units outstanding in each Class of each Series as of December 31, 2014:2015:

No Units are authorized for issuance by the Trust under equity compensation plans. During the year ended December 31, 2014,2015, no unregistered Units were sold by the Trust. In addition, the Trust did not repurchase any Units under a formal repurchase plan. All Unit redemptions during the year ended December 31, 20142015 were in the ordinary course of business. There have not been any purchases of units by the trust or any affiliated purchasers during the year ended December 31, 2014.2015.
