Organization and Purpose [Line Items]
Organization and Purpose	1. Organization and Purpose Frontier Funds, which is referred to in this report as the “Trust”, was formed on August 8, 2003, as a Delaware statutory trust. Please refer to the consolidated financial statements of the Trust included within this periodic report. The Trust is a multi-advisor commodity pool, as described in Commodity Futures Trading Commission (“CFTC”) Regulation § 4.10(d)(2). The Trust has authority to issue separate series, or each, a Series, of units of beneficial interest (the “Units”) pursuant to the requirements of the Delaware Statutory Trust Act, as amended (the “Trust Act”). The assets of each Series are valued and accounted for separately from the assets of other Series. The Trust is not registered as an investment company under the Investment Company Act of 1940, as amended (the “Investment Company Act”). It is managed by Frontier 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, as further amended, by and among the Managing Owner, Wilmington Trust Company as trustee and the unitholders, as may be amended from time to time (“Trust Agreement”), unitholders of the 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 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. The Trust has seven (7) separate and distinct Series of Units issued and outstanding: Frontier Diversified Fund, Frontier Masters Fund, Frontier Long/Short Commodity Fund, Frontier Balanced Fund, Frontier Select Fund, Frontier Global Fund, and Frontier Heritage Fund, (each a “Series” and collectively, the “Series”). The Trust, with respect to the Series, may issue additional Series of Units. The Trust, with respect to each Series: ● engages in the speculative trading of a diversified portfolio of futures, forwards (including interbank foreign currencies), options contracts and other derivative instruments (including swap contracts), and may, from time to time, engage in cash and spot transactions; ● allocates funds to a limited liability trading company or companies (“Trading Company” or “Trading Companies”) and Galaxy Plus (as defined below) entities. Except as otherwise described in these notes, each Trading Company and Galaxy Plus entity has one-year renewable contracts with its own independent commodity trading advisor (s), or each, a Trading Advisor, that will manage all or a portion of such Trading Company’s and Galaxy Plus assets and make the trading decisions for the assets of each Series invested in such Trading Company and Galaxy Plus entity. Each Trading Company and Galaxy Plus entity will segregate its assets from any other Trading Company and Galaxy Plus entity; ● maintains separate, distinct records for each Series, and accounts for the assets of each Series separately from the other Series; ● calculates the Net Asset Value (“NAV”) of its Units for each Series separately from the other Series; ● has an investment objective of increasing the value of each Series’ Units over the long term (capital appreciation), while managing risk and volatility; further, to offer exposure to the investment programs of individual Trading Advisors and to specific instruments; ● maintains each Series of Units in three to seven sub-classes—Class 1, Class 1AP, Class 1a, Class 2, Class 2a, Class 3, and Class 3a. Investors who have purchased Class 1 or Class 1a Units of Frontier Diversified Fund, Frontier Masters Fund, and Frontier Long/Short Commodity Fund are charged a service fee of up to two percent (2.0%) annually of the NAV (of the purchase price, in case of the initial service fee) of each Unit purchased, for the benefit of selling agents selling such Class 1 or Class 1a Units. The initial service fee, which is amortized monthly at an annual rate of up to two percent (2.0%) of the average daily NAV of Class 1 or Class 1a of such Series, is prepaid to the Managing Owner by each Series, and paid to the selling agents by the Managing Owner in the month following sale; provided, however, that investors who redeem all or a portion of their Class 1 or Class 1a Units of any Series during the first twelve (12) months following the effective date of their purchase are subject to a redemption fee of up to two percent (2.0%) of the purchase price at which such investor redeemed to reimburse the Managing Owner for the then-unamortized balance of the prepaid initial service fee. Investors who have purchased Class 1 or Class 1a Units of Frontier Balanced Fund, Frontier Heritage Fund, Frontier Select Fund, and Frontier Global Fund are charged a service fee of up to three percent (3.0%) annually of the NAV (of the purchase price, in case of the initial service fee) of each Unit purchased, for the benefit of selling agents selling such Class 1 or Class 1a Units. The initial service fee, which is amortized monthly at an annual rate of up to three percent (3.0%) of the average daily NAV of Class 1 or Class 1a of such Series, is prepaid to the Managing Owner by each Series, and paid to the selling agents by the Managing Owner in the month following sale. With respect to Class 2 and Class 2a Units of any Series, the Managing Owner pays an ongoing service fee to selling agents of up to one half percent (0.5%) annually of the NAV of each Class 2 or Class 2a Unit (of which 0.25% will be charged to Limited Owners holding Class 2 Units of the Frontier Diversified Fund, and Frontier Masters Fund or Class 2a Units of the Frontier Long/Short Commodity Fund 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. Class 1AP was created as a sub-class of Class 1 and it has been presented separately because the fees applicable to it are different from those applicable to Class 1. Currently the service fee is not charged to Class 1AP investors. The Managing Owner may also pay selling agents certain additional fees and expenses for administrative and other services rendered and expenses incurred by such selling agents; and ● all payments made to selling agents who are members of the Financial Industry Regulatory Authority, Inc. (“FINRA”) and their associated persons that constitute underwriting compensation will be subject to the limitations set forth in Rule 2310(b)(4)(B)(ii) (formerly Rule 2810(b)(4)(B)(ii)) of the Conduct Rules of FINRA (“Rule 2310”). An investor’s Class 1 Units or Class 2 Units of any Series, or Class 1a Units or Class 2a Units of the Frontier Long/Short Commodity Fund or Frontier Balanced Fund will be classified as Class 3 or Class 3a Units of such Series, as applicable, when the Managing Owner determines that the fee limitation set forth in Rule 2310 with respect to such Units has been reached or will be reached. The service fee limit applicable to each unit sold is reached upon the earlier of when (i) the aggregate initial and ongoing service fees received by the selling agent with respect to such unit equals 9% of the purchase price of such unit or (ii) the aggregate underwriting compensation (determined in accordance with FINRA Rule 2310) paid in respect of such unit totals 10% of the purchase price of such unit. No service fees are paid with respect to Class 3 or Class 3a Units. Units of any Class in a Series may be redeemed, in whole or in part, on a daily basis, at the then current NAV per Unit for such Series on the day of the week after the date the Managing Owner is in receipt of a redemption request for at least one (1) business day to be received by the Managing Owner prior to 4:00 PM in New York. The assets of any particular Series include only those funds and other assets that are paid to, held by or distributed to the Trust, with respect to the Series, 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, are maintained in the books and records of each Series. As of March 31, 2022, the Trust, with respect to the Frontier Diversified Fund and Frontier Masters Fund, separates Units into two separate Classes—Class 2 and Class 3. The Trust, with respect to the Frontier Select Fund, Frontier Global Fund and Frontier Heritage Fund separates Units into a maximum of three separate Classes—Class 1, Class 2 and Class 1AP. The Trust, with respect to the Frontier Balanced Fund separates Units into a maximum of five separate Classes—Class 1, Class 1AP, Class 2, Class 2A and Class 3A. The Trust, with respect to the Frontier Long/Short Commodity Fund separates Units into a maximum of five separate Classes—Class 1A, Class 2A, Class 2, Class 3A and Class 3. Between April 15, 2016 and May 10, 2017, a portion of the interests in Frontier Trading Company I, LLC and all of the interests in Frontier Trading Company VII, LLC, Frontier Trading Company XV, LLC, and Frontier Trading Company XXIII LLC held by Frontier Diversified Fund, Frontier Masters Fund, Frontier Select Fund, Frontier Balanced Fund and Frontier Long/Short Commodity Fund were exchanged for equivalent interests in the Galaxy Plus Managed Account Platform (“Galaxy Plus”) which is an unaffiliated, third-party managed account platform. The assets of Frontier Trading Company I, LLC, which included exposure to Quantmetrics Capital Management LLP’s Multi-Strategy Program, Quantitative Investment Management, LLC’s Quantitative Global Program, Quest Partners LLC’s Quest Tracker Index Program, Chesapeake Capital Management, LLC’s Diversified Program, and Doherty Advisors LLC’s Relative Value Moderate Program, the assets of Frontier Trading Company VII, LLC, which included exposure to Emil van Essen LLC’s Multi-Strategy Program, Red Oak Commodity Advisors, Inc.’s Fundamental Diversified Program, Rosetta Capital Management, LLC’s Rosetta Trading Program, and Landmark Trading Company’s Landmark Program, the assets of Frontier Trading Company XV, LLC, which included exposure to Transtrend B.V.’s TT Enhanced Risk (USD) Program, and the assets of Frontier Trading Company XXIII, LLC which included exposure to Fort L.P.’s Global Contrarian Program have been transferred to individual Delaware limited liability companies (“Master Funds”) in Galaxy Plus. Each Master Fund is sponsored and operated by Gemini Alternative Funds, LLC (“Sponsor”). The Sponsor has contracted with the Trading Advisors to manage the portfolios of the Master Funds pursuant to the advisors’ respective program. For those Series that invest in Galaxy Plus, approximately 30-70% of those Series assets are used to support the margin requirements of the Master Funds. The remaining assets of the Series are split between investments in Trading Companies and a pooled cash management account that invests primarily in U.S. Treasury securities. All the funds are invested in Galaxy Plus entities. Each of the Series has invested a portion of its assets in several different Trading Companies or Galaxy Plus entities and one or more Trading Advisors may manage the assets invested in such Trading Companies or Galaxy Plus entities. The Trust has entered into agreements, which provide for the indemnification of futures clearing brokers, currency trading companies, and commodity trading advisers, among others, against losses, costs, claims and liabilities arising from the performance of their individual obligations under such agreements, except for gross negligence, bad faith or willful misconduct.

Significant Accounting Policies [Line Items]
Significant Accounting Policies	2. Significant Accounting Policies The following are the significant accounting policies of the Series of the Trust. Basis of Presentation Consolidation Galaxy Plus entities are co-mingled investment vehicles. In addition to the Series, there are other non-affiliated investors in Galaxy Plus entities. Subscriptions and redemptions by these non-affiliated investors will have a direct impact on the Series’ ownership percentage in Galaxy Plus entities. It is expected that ownership percentage will fluctuate (sometimes significantly) on a week by week basis which could also result in frequent changes in the consolidating Series. Such fluctuations make consolidating the financial statements of the Galaxy Plus entities both impractical and misleading. Non-consolidation of these Galaxy Plus entities presents a more useful financial statement for the readers. As such, management has decided that presenting Galaxy Plus entities on a non-consolidated basis as investments in other investments companies (a “fund of funds” approach) is appropriate and preferable to the users of these financial statements. Refer to Note 5 for additional disclosures related to these private investment companies. Use of Estimates— Cash and Cash Equivalents— Interest Income U U.S. Treasury Securities— Fair Value Measurements and Disclosures (“ Receivable From Futures Commission Merchants—The Series of the Trust deposit assets with an FCM subject to CFTC regulations and various exchange and broker requirements. Margin requirements are satisfied by the deposit of cash with such FCM. The Trust, with respect to the Series, earns interest income on its assets deposited with the FCM. A portion of the receivable is restricted cash required to meet maintenance margin requirements. Cash with the clearing broker as of March 31, 2022 and December 31, 2021 included restricted cash for margin requirements of $236,513 and $801,701 respectively, for the Frontier Balanced Fund. Investment Transactions— Balance Sheet (“ASC 210” Balance Sheet (Topic 210 Any change in net unrealized gain or loss from the preceding period is reported in the statements of operations. Fair value of exchange-traded contracts is based upon exchange settlement prices. Fair value of non-exchange-traded contracts is based on third party quoted dealer values on the interbank market. For U.S. Treasury securities, interest is recognized in the period earned and the instruments are marked-to-market daily based on third party information. Transaction costs are recognized as incurred and reflected separately in the statements of operations. Purchase and Sales of Private Investment Companies Foreign Currency Transactions— Allocation of Earnings— Each Series allocates funds to an affiliated Trading Company, or Companies, of the Trust or unaffiliated Galaxy Plus entity. Each Trading Company allocates all of its daily trading gains or losses to the Series in proportion to each Series’ ownership trading level interest in the Trading Company, adjusted on a daily basis (except for Trading Advisors and other investments such as swaps that are directly allocated to a specific Series). Likewise, trading gains and losses earned and incurred by the Series through their investments in Galaxy Plus entities are allocated to those Series on a daily basis. The allocation of gains and losses in Galaxy Plus entities are based on each Series pro-rata shares of the trading level of that entity which is updated at the beginning of each month or more frequently if there is a subscription or redemption activity in the entity. The value of all open contracts and cash held at clearing brokers is similarly allocated to the Series in proportion to each Series’ funds allocated to the Trading Companies or Galaxy Plus entities. Investments and Swaps Income Taxes Income Taxes The 2018 through 2021 tax years generally remain subject to examination by U.S. federal and most state tax authorities. In the opinion of the Managing Owner, (i) the Trust, with respect to the Series, is treated as a partnership for federal income tax purposes and, assuming that at least 90% of the gross income of the Trust constitutes “qualifying income” within the meaning of Section 7704(d) of the Code, (ii) the Trust is not a publicly traded partnership treated as a corporation, and (iii) the discussion set forth in the Prospectus under the heading “U.S. Federal Income Tax Consequences” correctly summarizes the material federal income tax consequences as of the date of the Prospectus to potential U.S. Limited Owners of the purchase, ownership and disposition of Units of the Trust. Fees and Expenses Incentive Fee (rebate) Service Fees Each Series is charged service fees as outlined above. In some cases, amounts paid to selling agents might be less than the amount charged to the Series. When this occurs, the service fee is rebated back to the investor in the form of additional units. During 2020, 2021 and 2022 the Series were not allowed to issue additional units. The Managing Owner has determined that the purchase of additional units of the relevant Series will commence in 2022 when the Series are allowed to sell shares again. As such, the Managing Owner has calculated the amounts for additional units of the relevant series which will be purchased and classified such amounts as Subscriptions in advance for service fee rebates of $22,650, $393, $31,725, $374,556, $21,287, $159,581 and $71,693 for the Frontier Diversified, Long/Short Commodity, Masters, Balanced, Select, Global and Heritage Funds, respectively, as of March 31, 2022. These service fees are part of the offering costs of the Trust, with respect to the Series, which include registration and filing fees, legal and blue sky expenses, accounting and audit, printing, marketing support and other offering costs which are borne by the Managing Owner. With respect to the service fees, the initial service fee (for the first 12 months) relating to a purchase of Class 1 and Class 1a Units by an investor is prepaid by the Managing Owner to the relevant selling agent in the month following such purchase and is reimbursed for such payment by the Series monthly in arrears in an amount based upon a corresponding percentage of NAV, calculated daily. Consequently, the Managing Owner bears the risk of the downside and enjoys the benefit of the upside potential of any difference between the amount of the initial service fee prepaid by it and the amount of the reimbursement thereof, which may result from variations in NAV over the following 12 months. Pending Owner Additions— Owner redemptions payable— Recently Adopted Accounting Pronouncements— In August 2018, FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement (“ASU 2018-13”). The primary focus of ASU 2018-13 is to improve the effectiveness of the disclosure requirements for fair value measurements. The changes affect all companies that are required to include fair value measurement disclosures. In general, the amendments in ASU 2018-13 are effective for all entities for fiscal years and interim periods within those fiscal years, beginning after December 15, 2019. An entity is permitted to early adopt the removed or modified disclosures upon the issuance of ASU 2018-13 and may delay adoption of the additional disclosures, which are required for public companies only, until their effective date. Management has evaluated the impacts of ASU 2018-13 and ensured that the financial statements are compliant. Subsequent Events—The Series follow the provisions of ASC 855, Subsequent Events

Significant Accounting Policies [Line Items]
Significant Accounting Policies	2. Significant Accounting Policies The following are the significant accounting policies of the Trust. Basis of Presentation Consolidation The income or loss attributable thereto in proportion of investment level is shown in the statements of operations as net unrealized gain/(loss) on private investment companies. The Trading Companies and Series of the Trust are consolidated by the Trust. All intercompany transactions have been eliminated in consolidation. Galaxy Plus entities are co-mingled investment vehicles. In addition to the Trust, there are other non-affiliated investors in Galaxy Plus entities. Subscriptions and redemptions by these non-affiliated investors will have a direct impact on the Trust’s ownership percentage in Galaxy Plus entities. It is expected that ownership percentage will fluctuate (sometimes significantly) on a week by week basis which could also result in frequent changes in the consolidating Series. Such fluctuations make consolidating the financial statements of the Galaxy Plus entities both impractical and misleading. Non-consolidation of these Galaxy Plus entities presents a more useful financial statement for the readers. As such, management has decided that presenting Galaxy Plus entities on a non-consolidated basis as investments in other investments companies (a “fund of funds” approach) is appropriate and preferable to the users of these financial statements. Refer to Note 5 for additional disclosures related to these private investment companies. Use of Estimates— Cash and Cash Equivalents— Interest Income U.S. Treasury Securities— Fair Value Measurements and Disclosures (“ Receivable from Futures Commission Merchants Investment Transactions Balance Sheet (“ASC 210” Balance Sheet (Topic 210 Any change in net unrealized gain or loss from the preceding period is reported in the consolidated statements of operations. Fair value of exchange-traded contracts is based upon exchange settlement prices. Fair value of non-exchange-traded contracts is based on third party quoted dealer values on the interbank market. For U.S. Treasury securities, interest was recognized in the period earned and the instruments were marked-to-market daily based on third party information. Transaction costs are recognized as incurred and reflected separately in the consolidated statements of operations. Purchase and Sales of Private Investment Companies— Foreign Currency Transactions— Allocation of Earnings— Each Series allocates funds to an affiliated Trading Company, or Companies, of the Trust, or unaffiliated Galaxy Plus entity. Each Trading Company allocates all of its daily trading gains or losses to the Series in proportion to each Series’ ownership trading level interest in the Trading Company, adjusted on a daily basis (except for Trading Advisors and other investments such as swaps that are directly allocated to a specific series). Likewise, trading gains and losses earned and incurred by the Series through their investments in Galaxy Plus entities are allocated to those Series on a daily basis. The allocation of gains and losses in Galaxy Plus entities are based on each Series pro-rata shares of the trading level of that entity which is updated at the beginning of each month or more frequently if there is a subscription or redemption activity in the entity. The value of all open contracts and cash held at clearing brokers is similarly allocated to the Series in proportion to each Series’ funds allocated to the Trading Companies or Galaxy Plus entities. Investments and Swaps— Income Taxes The 2018 through 2021 tax years generally remain subject to examination by U.S. federal and most state tax authorities. In the opinion of the Managing Owner, (i) the Trust is treated as a partnership for Federal income tax purposes and, assuming that at least 90% of the gross income of the Trust constitutes “qualifying income” within the meaning of Section 7704(d) of the Code, (ii) the Trust is not a publicly traded partnership treated as a corporation, and (iii) the discussion set forth in the Prospectus under the heading “U.S. Federal Income Tax Consequences” correctly summarizes the material Federal income tax consequences as of the date of the Prospectus to potential U.S. Limited Owners of the purchase, ownership and disposition of Series Units of the Trust.

Fair Value Measurements	3. Fair Value Measurements In connection with the valuation of investments the Series apply ASC 820. ASC 820 provides clarification that when a quoted price in an active market for the identical asset or liability is not available, a reporting entity is required to measure fair value using certain techniques. ASC 820 also clarifies that when estimating the fair value of an asset or liability, a reporting entity is not required to include a separate input or adjustment to other inputs relating to the existence of a restriction that prevents the transfer of an asset or liability. ASC 820 also clarifies that both a quoted price in an active market for the identical asset or liability at the measurement date and the quoted price for the identical asset or liability when traded as an asset in an active market when no adjustments to the quoted price of the asset are required are Level 1 fair value measurements. Level 1 Inputs Unadjusted quoted prices in active markets for identical financial assets that the reporting entity has the ability to access at the measurement date. Level 2 Inputs Inputs other than quoted prices included in Level 1 that are observable for the financial assets or liabilities, either directly or indirectly. These might include quoted prices for similar financial assets in active markets, quoted prices for identical or similar financial assets in markets that are not active, inputs other than quoted prices that are observable for the financial assets or inputs that are derived principally from or corroborated by market data by correlation or other means. Level 3 Inputs Unobservable inputs for determining the fair value of financial assets that reflect an entity’s own assumptions about the assumptions that market participants would use in pricing the financial asset. The Trust, with respect to the Series, uses the following methodologies to value instruments within its financial asset portfolio at fair value: Trading Securities Swap Contracts. Swap contracts are reported at fair value. Valuation reports are generated and disseminated daily from the swap counterparty to the third-party administrator. The fair value is applied by the third-party administrator to calculate the daily performance. The Managing Owner reviews the third-party administrator performance reports and any noticeable exceptions are investigated. Unexplained exceptions are escalated to the Managing Owner’s Valuation Committee for further evaluation and resolution. Swap contracts are reported at fair value using Level 3 inputs.

Swap Contracts	4. Swap Contracts In addition to authorizing Trading Advisors to manage predetermined investment levels of futures, option on futures and forward contracts, certain Series of the Trust will strategically invest a portion or all of their assets in total return swaps, selected at the direction of the Managing Owner. Total return swaps are privately negotiated contracts designed to provide investment returns linked to those produced by one or more investment products or indices. In a typical total return swap, two parties agree to exchange the returns (or differentials in rates of return) earned or realized on one or more particular predetermined investments or instruments. The gross returns to be exchanged or “swapped” between the parties are calculated with respect to a “notional amount” (i.e., the amount or value of the underlying asset used in computing the particular interest rate, return, or other amount to be exchanged) in a particular investment, or in a “basket” of securities. Each Series’ investment in swaps will likely differ substantially over time due to cash flows, portfolio management decisions and market movements. The swaps serve to diversify the investment holdings of each Series and to provide access to programs and advisors that would not be otherwise available to the Series, and are not used for hedging purposes. The Managing Owner follows a procedure in selecting well-established financial institutions which the Managing Owner, in its sole discretion, considers to be reputable, reliable, financially responsible and well established to act as swap counterparties. The procedure includes due diligence review of documentation on all new and existing financial institution counterparties prior to initiation of the relationship, and quarterly ongoing review during the relationship, to ensure that counterparties meet the Managing Owner’s minimum credit requirements, the counterparty average rating being no less than an investment grade rating as defined by the rating agencies. As of March 31, 2022, none of the Trust’s assets were deposited with over-the-counter counterparties in order to initiate and maintain swaps and is recorded as collateral within the swap fair value within the Statements of Financial Condition. The cash held with the counterparty is not restricted. The Series may strategically invest assets in one or more swaps linked to certain underlying investments or indices at the direction of the Managing Owner. The Trading Company in which the assets of these Series will be invested will not own any of the investments or indices referenced by any swap entered into by these Series. In addition, neither the swap counterparty to the Trading Company of these Series nor any advisor referenced by any such swap is a Trading Advisor to these Series. To help to reduce counterparty risk on the Series, the Managing Owner has the right to reduce the Series’ exposure and remove cash from the Series’ total return swaps with Deutsche Bank AG. This cash holding shall be in excess of $250,000 and may not exceed 40% of the index exposure in total. Index exposure is defined as the total notional amount plus any profit. The Series are charged interest on this cash holding and any amount removed will be offset against the final settlement value of the swap. All swap investments were liquidated in the year 2020.

Investments in Private Investment Companies Investments in private investment companies represent cash and open trade equity invested in the private investment companies as well as the cumulative trading profits or losses allocated to the Trust by the private investment companies. Private investment companies allocate trading profits or losses on the basis of the proportion of the Trust’s capital allocated for trading to each respective private investment company, which bears no relationship to the amount of cash invested by the Trust in the private investment companies. Investments in private investment companies are valued using the NAV provided by the underlying private investment. The Galaxy Plus structure is made up of feeder funds in which the Trust invests and master trading entities into which the feeder funds invest. No investment held by a Galaxy Plus master trading entity is greater than 5% of the Trust’s total capital.

Transactions with Affiliates	6. Transactions with Affiliates The Managing Owner contributes funds to the Trust, with respect to the Series, in order to have a 1% interest (“Minimum Purchase Commitment”) in the aggregate capital, profits and losses of all Series and in return will receive units designated as general units in the Series in which the Managing Owner invests such funds. The general units may only be purchased by the Managing Owner and may be subject to no management fees or management fees at reduced rates. Otherwise, the general units hold the same rights as the limited units. 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 the combined Series of the Trust. Such contribution was made by the Managing Owner before trading commenced for the Trust and will be maintained throughout the existence of the Trust, and the Managing Owner will make such purchases as are necessary to effect this requirement. Additionally, the Managing Owner agreed with certain regulatory bodies to maintain a 1% interest specifically in the Frontier Balanced Fund Class 1AP and 2a Units, aggregated, and each of the Frontier Long/Short Commodity Fund, Frontier Diversified Fund and Frontier Masters Fund. The 1% interest in these specific Series is included in computing the Minimum Purchase Commitment in aggregate capital. In addition to the general units the Managing Owner receives in respect of its Minimum Purchase Commitment, the Managing Owner may purchase limited units in any Series as a Limited Owner. Principals of the Managing Owner or affiliates are allowed to own beneficial interests in the Trust, with respect to the Series, as well. All Units purchased by the Managing Owner are held for investment purposes only and not for resale. The Managing Owner may make purchases or redemptions at any time on the same terms as any Limited Owner. The Trust has and will continue to have certain relationships with the Managing Owner and its affiliates. Expenses Management Fees— The management fee as a percentage of the applicable Series’ notional assets will be greater than the percentage of the applicable Series’ net asset value to the extent that the notional assets of the Series exceeds its net asset value. The Managing Owner expects that the notional assets of each Series will generally be maintained at a level in excess of the net asset value of such Series and such excess may be substantial to the extent the Managing Owner deems necessary to achieve the desired level of volatility. Trading Fees— Incentive Fees— Service Fees— Units of the Frontier Diversified Fund and Frontier Masters Fund or Class 2a Units of the Frontier Long/Short Commodity Fund sold) until such Class 2 or Class 2a Units which are subject to the fee limitation are reclassified as Class 3 or Class 3a Units of the applicable Series for administrative purposes. Currently the service fee is not charged to Class 1AP investors. 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. The Managing Owner has determined that the purchase of additional units of the relevant series will commence in 2021. As such, the Managing Owner has calculated the amounts for additional units of the relevant series which will be purchased and classified such amounts as Subscriptions in advance for service fee rebates of $22,650, $393, $31,725, $374,556, $21,287, $159,581 and $71,693 for the Frontier Diversified, Long/Short Commodity, Masters, Balanced, Select, Global and Heritage Funds, respectively, as of March 31, 2022.

Consequently, the Managing Owner bears the risk and the benefit of the upside potential of any difference between the amount of the initial service fee prepaid by it and the amount of the reimbursement thereof, which may result from variations in NAV over the following 12 months. Aggregate interest income from all sources, including U.S. Treasury Securities assets net of premiums and cash held at clearing brokers, of up to the first 2% (annualized) of average net assets less any fair market value related to swaps is paid to the Managing Owner by the Frontier Balanced Fund (Class 1 and Class 2), Frontier Long/Short Commodity Fund (Class 2 and Class 3), Frontier Global Fund, Frontier Select Fund, and Frontier Heritage Fund.

Transactions with Affiliates	6. Transactions with Affiliates The Managing Owner contributes funds to the Trust in order to have a 1% interest in the aggregate capital, profits and losses and in return will receive units designated as general units in the Series of the Trust in which the Managing Owner invests such funds. The general units may only be purchased by the Managing Owner and may be subject to no advisory fees or management advisory fees at reduced rates. Otherwise, the general units hold the same rights as the limited units. The Managing Owner is required to maintain at least a 1% interest (“Minimum Purchase Commitment”) in the aggregate capital, profits and losses of the Trust so long as it is acting as the Managing Owner of the Trust. Such contribution was made by the Managing Owner before trading commenced for the Trust and will be maintained throughout the existence of the Trust, and the Managing Owner will make such purchases as are necessary to effect this requirement. Additionally, the Managing Owner agreed with certain regulatory bodies to maintain a 1% interest specifically in the Frontier Balanced Fund Class 1AP Units and Frontier Balanced Fund Class 2a Units, aggregated, and each of the Frontier Long/Short Commodity Fund, Frontier Diversified Fund, and Frontier Masters Fund. The 1% interest in these specific Series of the Trust is included in computing the Minimum Purchase Commitment in aggregate capital. In addition to the general units the Managing Owner receives in respect of its Minimum Purchase Commitment, the Managing Owner may purchase limited units in any Series as a Limited Owner. Principals of the Managing Owner or affiliates are allowed to own beneficial interests in the Trust, as well. All units purchased by the Managing Owner are held for investment purposes only and not for resale.

The Managing Owner expects that the notional assets of each Series will generally be maintained at a level in excess of the net asset value of such Series and such excess may be substantial to the extent the Managing Owner deems necessary to achieve the desired level of volatility. Trading Fees— Incentive Fees— It is therefore possible that in any given period the Series may pay incentive fees to the Managing Owner for one or more Trading Advisors while each of these Series as a whole experiences losses. The incentive fee is 25% for the Frontier Balanced Fund and the Frontier Diversified Fund and 20% for the Frontier Global Fund, Frontier Heritage Fund, Frontier Select Fund, Frontier Long/Short Commodity Fund and Frontier Masters Fund. The Managing Owner may pay all or a portion of such incentive fees to the Trading Advisor(s) for such Series. Service Fees— As of March 31, 2022, the Trust had a payable to the Managing Owner in the amounts of $76,963, $1,601, $2,081, $80,225 and $38,007 for incentive fees, management fees, interest, trading fees, and service fees, respectively.

With respect to the service fees, the initial service fee (for the first 12 months) relating to a purchase of Units by an investor is prepaid by the Managing Owner to the relevant selling agent in the month following such purchase and is reimbursed therefore by the Series monthly in arrears in an amount based upon a corresponding percentage of NAV, calculated daily. Consequently, the Managing Owner bears the risk and enjoys the benefit of the upside potential of any difference between the amount of the initial service fee prepaid by it and the amount of the reimbursement thereof, which may result from variations in NAV over the following 12 months. Aggregate interest income from all sources, including U.S. Treasury Securities assets net of premiums and cash held at clearing brokers, of up to the first 2% (annualized) is paid to the Managing Owner by the Frontier Balanced Fund (Class 1 and Class 2 only), Frontier Long/Short Commodity Fund (Class 2 and Class 3), Frontier Global Fund, Frontier Select Fund, and Frontier Heritage Fund. For the Frontier Diversified Fund, Frontier Long/Short Commodity Fund (for the three months ended March 31, 2022, and March 31, 2021 amounts received or receivable from the Managing Owner for the difference in monthly service fees from the prepaid initial service fees Class 1a, Class 2a and Class 3a), Frontier Masters Fund, and Frontier Balanced Fund (Class 1AP, Class 2a and Class 3a), 100% of the interest is retained by the respective Series.

Trading Activities and Related Risks [Line Items]
Trading Activities and Related Risks	9. Trading Activities and Related Risks The purchase and sale of futures and options on futures contracts require margin deposits with FCMs. Additional deposits may be necessary for any loss on contract value. The Commodity Exchange Act, as amended (“CEA”), requires an FCM to segregate all customer transactions and assets from the FCM’s proprietary activities. A customer’s cash and other property (for example, U.S. treasury bills) deposited with an FCM are considered commingled with all other customer funds subject to the FCM’s segregation requirements. In the event of an FCM’s insolvency, recovery may be limited to a pro rata share of segregated funds available. It is possible that the recovered amount could be less than the total of cash and other property deposited. The term “off-balance sheet risk” refers to an unrecorded potential liability that, even though it does not appear on the statements of financial condition, may result in future obligation or loss in excess of the amount paid by the Series for a particular investment. Each Trading Company expects to trade in futures, options, forward and swap contracts and will therefore be a party to financial instruments with elements of off-balance sheet market and credit risk. In entering into these contracts, there exists a market risk that such contracts may be significantly influenced by market conditions, such as interest rate volatility, resulting in such contracts being less valuable. If the markets should move against all of the futures positions held by a Trading Company or Galaxy Plus entity in respect of any Series at the same time, and if the Trading Advisor(s) of such Trading Company or Galaxy Plus entity are unable to offset such futures interests positions, such Trading Company or Galaxy Plus entity could lose all of its assets and the holders of Units of such Series would realize a 100% loss. The Managing Owner will seek to minimize market risk through real-time monitoring of open positions and the level of diversification of each Trading Advisor’s portfolio. It is anticipated that any Trading Advisor’s margin-to-equity ratio will typically not exceed approximately 35% although the actual ratio could be higher or lower from time to time. In addition to market risk, trading futures, forward and swap contracts entails credit risk that a counterparty will not be able to meet its obligations to a Trading Company or Galaxy Plus entity. The counterparty for futures contracts traded in the United States and on most foreign exchanges is the clearinghouse associated with such exchange. In general, clearinghouses are backed by the corporate members of the clearinghouse who are required to share any financial burden resulting from the non-performance by one of their members and, as such, should significantly reduce this credit risk. In cases where the clearinghouse is not backed by the clearing members, like some foreign exchanges, it is normally backed by a consortium of banks or other financial institutions. Some non-U.S. exchanges, in contrast to U.S. exchanges, are principals’ markets in which performance is the responsibility only of the individual counterparty with whom the Trading Company has entered into the transaction, and not of the exchange or clearing corporation. In these kinds of markets, there is risk of bankruptcy or other failure or refusal to perform by the counterparty. In the case of forward contracts traded on the interbank market and swaps, neither is traded on exchanges. The counterparty is generally a single bank or other financial institution, rather than a group of financial institutions; thus there may be a greater counterparty credit risk. The Managing Owner expects the Trading Advisors to trade only with those counterparties which it believes to be creditworthy. All positions of each Trading Company will be valued each day on a mark-to-market basis. There can be no assurance that any clearing member, clearinghouse or other counterparty will be able to meet its obligations to any Trading Company. The Managing Owner has established procedures to actively monitor and minimize market and credit risks. The Limited Owners bear the risk of loss only to the extent of the market value of their respective investments and, in certain specific circumstances, distributions and redemptions received.

If the markets should move against all of the futures positions held by a Trading Company or Galaxy Plus entity in respect of any Series at the same time, and if the Trading Advisor(s) of such Trading Company or Galaxy Plus entity are unable to offset such futures interests positions, such Trading Company or Galaxy Plus entity could lose all of its assets and the holders of Units of such Series would realize a 100% loss. The Managing Owner will seek to minimize market risk through real-time monitoring of open positions and the level of diversification of each Trading Advisor’s portfolio. It is anticipated that any Trading Advisor’s margin- to-equity ratio will typically not exceed approximately 35% although the actual ratio could be higher or lower from time to time. In addition to market risk, trading futures, forward and swap contracts entails credit risk that a counterparty will not be able to meet its obligations to a Trading Company or Galaxy Plus entity. The counterparty for futures contracts traded in the United States and on most foreign exchanges is the clearinghouse associated with such exchange. In general, clearinghouses are backed by the corporate members of the clearinghouse who are required to share any financial burden resulting from the non-performance by one of their members and, as such, should significantly reduce this credit risk. In cases where the clearinghouse is not backed by the clearing members, like some foreign exchanges, it is normally backed by a consortium of banks or other financial institutions. Some non-U.S. exchanges, in contrast to U.S. exchanges, are principals’ markets in which performance is the responsibility only of the individual counterparty with whom the Trading Company has entered into the transaction, and not of the exchange or clearing corporation. In these kinds of markets, there is risk of bankruptcy or other failure or refusal to perform by the counterparty. In the case of forward contracts traded on the interbank market and swaps, neither is traded on exchanges. The counterparty is generally a single bank or other financial institution, rather than a group of financial institutions; thus there may be a greater counterparty credit risk. The Managing Owner expects the Trading Advisors to trade only with those counterparties which it believes to be creditworthy. All positions of each Trading Company will be valued each day on a mark-to-market basis. There can be no assurance that any clearing member, clearinghouse or other counterparty will be able to meet its obligations to any Trading Company. The Managing Owner has established procedures to actively monitor and minimize market and credit risks. The Limited Owners bear the risk of loss only to the extent of the market value of their respective investments and, in certain specific circumstances, distributions and redemptions received.

Indemnifications and Guarantees noted in Management Discussion and Analysis The Trust has entered into agreements, which provide for the indemnification of futures clearing brokers, and commodity trading advisers, among others, against losses, costs, claims and liabilities arising from the performance of their individual obligations under such agreements, except for gross negligence, bad faith or willful misconduct. The Trust has had no prior claims or payments pursuant to these agreements. The Trust’s individual maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Trust that have not yet occurred. However, based on experience the Trust expects the risk of loss to be remote. Maximum exposure is unfulfilled obligations of the Series up to the amount of equity at risk with the custodian of the referenced Series as allocated from the Trading Company. The Series have not recorded any liability for the indemnifications in the accompanying financial statements as it expects any possibility of losses to be remote.

Consolidation	Consolidation Galaxy Plus entities are co-mingled investment vehicles. In addition to the Series, there are other non-affiliated investors in Galaxy Plus entities. Subscriptions and redemptions by these non-affiliated investors will have a direct impact on the Series’ ownership percentage in Galaxy Plus entities. It is expected that ownership percentage will fluctuate (sometimes significantly) on a week by week basis which could also result in frequent changes in the consolidating Series. Such fluctuations make consolidating the financial statements of the Galaxy Plus entities both impractical and misleading. Non-consolidation of these Galaxy Plus entities presents a more useful financial statement for the readers. As such, management has decided that presenting Galaxy Plus entities on a non-consolidated basis as investments in other investments companies (a “fund of funds” approach) is appropriate and preferable to the users of these financial statements. Refer to Note 5 for additional disclosures related to these private investment companies.

When this occurs, the service fee is rebated back to the investor in the form of additional units. During 2020, 2021 and 2022 the Series were not allowed to issue additional units. The Managing Owner has determined that the purchase of additional units of the relevant Series will commence in 2022 when the Series are allowed to sell shares again. As such, the Managing Owner has calculated the amounts for additional units of the relevant series which will be purchased and classified such amounts as Subscriptions in advance for service fee rebates of $22,650, $393, $31,725, $374,556, $21,287, $159,581 and $71,693 for the Frontier Diversified, Long/Short Commodity, Masters, Balanced, Select, Global and Heritage Funds, respectively, as of March 31, 2022. These service fees are part of the offering costs of the Trust, with respect to the Series, which include registration and filing fees, legal and blue sky expenses, accounting and audit, printing, marketing support and other offering costs which are borne by the Managing Owner. With respect to the service fees, the initial service fee (for the first 12 months) relating to a purchase of Class 1 and Class 1a Units by an investor is prepaid by the Managing Owner to the relevant selling agent in the month following such purchase and is reimbursed for such payment by the Series monthly in arrears in an amount based upon a corresponding percentage of NAV, calculated daily. Consequently, the Managing Owner bears the risk of the downside and enjoys the benefit of the upside potential of any difference between the amount of the initial service fee prepaid by it and the amount of the reimbursement thereof, which may result from variations in NAV over the following 12 months.

[1]	Interest income and expenses per unit are calculated by dividing these amounts by the average number of units outstanding during the period. The net gain/(loss) on investments, net of non-controlling interests is a balancing amount necessary to reconcile the change in net asset value per unit with the other per unit information.
[2]	Expense ratios do not include management and incentive fees at the Galaxy Plus entities. The ratios would have been higher had those expenses been included. The impact of those fees are included in the total return.
[3]	Expense ratios do not reflect interest allocated to the Managing Owner as such expenses are not included in the Statements of Operations of the Series, see footnote 6.

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