Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	(1) Organization ETF Managers Group Commodity Trust I (the “Trust”) was organized as a Delaware statutory trust on July 23, 2014. The Trust is a series trust formed pursuant to the Delaware Statutory Trust Act and currently includes two separate series. SIT RISING RATE ETF (“RISE”) is the first series of the Trust and is a commodity pool that continuously issues common shares of beneficial interest that may be purchased and sold on the NYSE Arca, Inc. stock exchange (“NYSE Arca”). The second series of the Trust, Breakwave Dry Bulk Shipping ETF (“BDRY,” and together with RISE, the “Funds”), is also a commodity pool that continuously issues shares of beneficial interest that may be purchased and sold on NYSE Arca. The Funds are managed and controlled by ETF Managers Capital LLC (the “Sponsor”), a Delaware limited liability company. The Sponsor is registered with the Commodity Futures Trading Commission (“CFTC”) as a “commodity pool operator” (“CPO”) and is a member of the National Futures Trading Association (“NFA”). Sit Fixed Income Advisors II, LLC (“Sit”), a subsidiary of Sit Investment Associates, Inc., is registered as a “commodity trading advisor” (“CTA”) with the CFTC and serves as RISE’s commodity trading advisor. Breakwave Advisors, LLC (“Breakwave”) is registered as a CTA with the CFTC and serves as BDRY’s commodity trading advisor. RISE commenced investment operations on February 19, 2015. RISE commenced trading on NYSE Arca on February 19, 2015 and trades under the symbol “RISE.” BDRY commenced investment operations on March 22, 2018. BDRY commenced trading on NYSE Arca on March 22, 2018 and trades under the symbol “BDRY.” For the period from January 27, 2016 through December 31, 2017, RISE paid Sit a fee equal to 0.50% per annum of the value of RISE’s average daily net assets for Sit’s services as the commodity trading advisor to RISE. Effective January 1, 2018, Sit is paid a fee equal to 0.20% per annum. RISE’s investment objective is to profit from rising interest rates by tracking the performance of a portfolio (the “RISE Benchmark Portfolio”) consisting of exchange traded futures contracts and options on futures on 2, 5 and 10 year U.S. Treasury securities (“Treasury Instruments”) weighted to achieve a targeted negative 10-year average effective portfolio duration (the “Benchmark Component Instruments”). RISE seeks to achieve its investment objective by investing in the Benchmark Component Instruments currently constituting the RISE Benchmark Portfolio. The RISE Benchmark Portfolio is maintained by Sit and will be rebalanced, reconstituted, or both, monthly (typically on the 15 th th The weighting of the Treasury Instruments constituting the Benchmark Component Instruments will be based on each maturity’s duration contribution. The expected range for the duration weighted percentage of the 2 year and 5 year maturity Treasury Instruments will be from 30% to 70%. The expected range for the duration weighted percentage of the 10-year maturity Treasury Instruments will be from 5% to 25%. The relative weightings of the Benchmark Component Instruments will be shifted between maturities when there are material changes in the shape of the yield curve, for example, if the Federal Reserve began raising short term interest rates more than long term interest rates. In such an instance, Sit, which maintains the RISE Benchmark Portfolio, will elect to increase the weightings of the 2 year and reduce the weighting in the 10-year maturity. Conversely, Sit will do the opposite if the Federal Reserve began raising long term interest rates more than short term interest rates. Reconstitution and rebalancing each will occur monthly, on the 15th, except for as noted above or if there are radical changes in the yield curve such that effective duration is outside of a range from negative nine to negative 11-year average effective duration, in which case Sit will adjust the maturities of the Treasury Instruments before the next expected monthly reconstitution. The Sponsor anticipates that approximately 5% to 15% of RISE’s assets will be used as payment for or collateral for Treasury Instruments. In order to collateralize its Treasury Instrument positions, RISE will hold such assets, from which it will post margin to its futures commission merchant (“FCM”), SG Americas Securities, LLC, in an amount equal to the margin required by the relevant exchange, and transfer to its FCM any additional amounts that may be separately required by the FCM. When establishing positions in Treasury Instruments, RISE will be required to deposit initial margin with a value of approximately 3% to 10% of the value of each Treasury Instrument position at the time it is established. These margin requirements are subject to change from time to time by the exchange or the FCM. On a daily basis, RISE will be obligated to pay, or entitled to receive, variation margin in an amount equal to the change in the daily settlement level of its Treasury Instruments positions. Any assets not required to be posted as margin with the FCM will be held at RISE’s custodian in cash or cash equivalents, as discussed below. The RISE Benchmark Portfolio will be invested in Benchmark Component Instruments and rebalanced, as noted above to maintain a negative average effective portfolio duration of approximately 10 years. Duration is a measure of estimated price sensitivity relative to changes in interest rates. Portfolios with longer durations are typically more sensitive to changes in interest rates. For example, if interest rates rise by 1%, the market value of a security with an effective duration of 5 years would decrease by 5%, with all other factors being constant, and likewise the market value of a security with an effective duration of negative 5 years would increase by 5%, with all other factors being constant. The correlation between duration and price sensitivity is greater for securities rated investment-grade than it is for securities rated below investment-grade. Duration estimates are based on assumptions by Sit and are subject to a number of limitations. Effective duration is calculated based on historical price changes of U.S. Treasuries and Treasury Instruments held by the RISE Benchmark Portfolio, and therefore is a more accurate estimate of price sensitivity provided interest rates remain within their historical range. Investments in debt securities typically decrease in value when interest rates rise. The risk is usually greater for longer-term debt securities. When RISE purchases an option that expires “out of the money,” RISE will realize a loss. RISE may not be able to invest its assets in futures and options contracts having an aggregate notional amount exactly equal to that which is required to achieve a negative 10-year average effective duration. For example, as standardized contracts, U.S. Treasury futures contracts are denominated in specific dollar amounts, and RISE’s NAV and the proceeds from the sale of a Creation Basket are unlikely to be an exact multiple of the amounts of those contracts. As a result, in such circumstances, RISE may be better able to achieve the exact amount of exposure desired through the use of other investments. BDRY’s investment objective is to provide investors with exposure to the daily change in the price of dry bulk freight futures, before expenses and liabilities of BDRY, by tracking the performance of a portfolio (the “BDRY Benchmark Portfolio”, and together with the RISE Benchmark Portfolio, the “Benchmark Portfolios”) consisting of a three-month strip of the nearest calendar quarter of futures contracts on specified indexes (each a “Reference Index”) that measure rates for shipping dry bulk freight (“Freight Futures”). Each Reference Index is published each United Kingdom business day by the London-based Baltic Exchange Ltd. (the “Baltic Exchange”) and measures the charter rate for shipping dry bulk freight in a specific size category of cargo ship – Capesize, Panamax or Supramax. The three Reference Indexes are as follows: ● Capesize ● Panamax ● Supramax The value of the Capesize 5TC Index is disseminated at 11:00 a.m., London Time and the value of the Panamax 4TC Index and the Supramax 6TC Index each is disseminated at 1:00 p.m., London Time. The Reference Index information disseminated by the Baltic Exchange also includes the components and value of each component in each Reference Index. Such Reference Index information also is widely disseminated by Reuters and/or other major market data vendors. BDRY seeks to achieve its investment objective by investing substantially all of its assets in the Freight Futures currently constituting the BDRY Benchmark Portfolio. The BDRY Benchmark Portfolio includes all existing positions to maturity and settles them in cash. During any given calendar quarter, the BDRY Benchmark Portfolio progressively increases its positions to the next calendar quarter three-month strip, thus maintaining constant exposure to the Freight Futures market as positions mature. The BDRY Benchmark Portfolio maintains long-only positions in Freight Futures. The BDRY Benchmark Portfolio includes a combination of Capesize, Panamax and Supramax Freight Futures. More specifically, the BDRY Benchmark Portfolio includes 50% exposure in Capesize Freight Futures contracts, 40% exposure in Panamax Freight Futures contracts and 10% exposure in Supramax Freight Futures contracts. The BDRY Benchmark Portfolio does not include and BDRY does not invest in swaps, non-cleared dry bulk freight forwards or other over-the-counter derivative instruments that are not cleared through exchanges or clearing houses. BDRY may hold exchange-traded options on Freight Futures. The BDRY Benchmark Portfolio is maintained by Breakwave and will be rebalanced annually. The Freight Futures currently constituting the BDRY Benchmark Portfolio, as well as the daily holdings of BDRY are available on BDRY’s website at www.drybulketf.com When establishing positions in Freight Futures, BDRY will be required to deposit initial margin with a value of approximately 10% to 40% of the notional value of each Freight Futures position at the time it is established. These margin requirements are established and subject to change from time to time by the relevant exchanges, clearing houses or BDRY’s FCM, MacQuarie Futures USA LLC. On a daily basis, BDRY is obligated to pay, or entitled to receive, variation margin in an amount equal to the change in the daily settlement level of its Freight Futures positions. Any assets not required to be posted as margin with the FCM may be held at BDRY’s custodian or remain with the FCM in cash or cash equivalents, as discussed below. BDRY was created to provide investors with a cost-effective and convenient way to gain exposure to daily changes in the price of Freight Futures. BDRY is intended to be used as a diversification opportunity as part of a complete portfolio, not a complete investment program. The Funds will incur certain expenses in connection with their operations. The Funds will hold cash or cash equivalents such as U.S. Treasuries or other high credit quality, short-term fixed-income or similar securities for direct investment or as collateral for the Treasury Instruments and for other liquidity purposes and to meet redemptions that may be necessary on an ongoing basis. These expenses and income from the cash and cash equivalent holdings may cause imperfect correlation between changes in the Funds’ net asset value (“NAV”) and changes in the Benchmark Portfolios, because the Benchmark Portfolios do not reflect expenses or income. The Funds seek to trade their positions prior to maturity; accordingly, natural market forces may cost the Funds while rebalancing. Each time the Funds seek to reconstitute their positions, barring movement in the underlying securities, the futures and option prices may be higher or lower. Such differences in price, barring a movement in the price of the underlying security, will constitute “roll yield” and may inhibit the Funds’ ability to achieve their respective investment objective. Several factors determine the total return from investing in a futures contract position. One factor that impacts the total return that will result from investing in near month futures contracts and “rolling” those contracts forward each month is the price relationship between the current near month contract and the next month contract. The CTA will close existing positions when it determines it would be appropriate to do so and reinvest the proceeds in other positions. Positions may also be closed out to meet orders for redemption baskets.

Summary of Significant Accounti

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	(2) Summary of Significant Accounting Policies (a) Basis of Accounting The accompanying financial statements of the Funds have been prepared in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”). Each Fund qualifies as an investment company for financial reporting purposes under Topic 946 of the Accounting Standard Codification of U.S. GAAP. The accompanying combined financial statements are unaudited, but in the opinion of management, contain all adjustments (which include normal recurring adjustments) considered necessary to present fairly the financial statements. These interim financial statements should be read in conjunction with RISE’s annual report on Form 10-K for the year ended June 30, 2018, RISE’s prospectus dated January 22, 2018 (the “RISE Prospectus”) and BDRY’s prospectus dated March 13, 2018 (the “BDRY Prospectus,” and together with the RISE Prospectus, the “Prospectuses”). Interim period results are not necessarily indicative of results for a full-year period. (b) Use of Estimates The preparation of the combined financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the combined financial statements and accompanying notes. Actual results could differ from those estimates. There were no significant estimates used in the preparation of the combined financial statements. (c) Cash Cash, when shown in the Combined Statements of Assets and Liabilities, represents non-segregated cash with the custodian and does not include short-term investments. (d) Cash Held by Broker Sit is registered as a “commodity trading advisor” and acts as such for RISE. Breakwave is registered as a “commodity trading advisor” and acts as such for BDRY. Each Fund’s arrangement with its respective FCM requires the Fund to meet its variation margin requirement related to the price movements, both positive and negative, on futures contracts held by the Fund by keeping cash on deposit with the Commodity Brokers (as defined below). These amounts are shown as Segregated cash held by broker in the Combined Statements of Assets and Liabilities. The Funds deposit cash or United States Treasury Obligations, as applicable, with their respective FCM subject to the CFTC regulations and various exchange and broker requirements. The combination of the Funds’ deposits with their respective FCM of cash and United States Treasury Obligations, as applicable, and the unrealized gain or loss on open futures contracts (variation margin) represents the Funds’ overall equity in their respective brokerage trading account. The Funds use their cash held by their respective FCM to satisfy variation margin requirements. The Funds earn interest on their cash deposited with their respective FCM and interest income is recorded on the accrual basis. (e) Final Net Asset Value for Fiscal Period The calculation time of each Fund’s final net asset value for creation and redemption of Fund shares for the three months ended September 30, 2018 and 2017 was at 4:00 p.m. Eastern Time on September 28, 2018 and September 29, 2017, respectively. Although the Funds’ shares may continue to trade on secondary markets subsequent to the calculation of the final NAV, the 4:00 p.m. Eastern Time represented the final opportunity to transact in creation or redemption baskets for the three months ended September 30, 2018 and 2017. Fair value per share is determined at the close of the NYSE Arca. For financial reporting purposes, each Fund values its investment positions based upon the final closing price in their primary markets. Accordingly, the investment valuations in these financial statements differ from those used in the calculations of the Funds’ final creation/redemption NAVs at September 28, 2018 and June 30, 2018. (f) Investment Valuation Short-term investments, excluding U.S. Treasury Bills, are carried at amortized cost, which approximates fair value. U.S. Treasury Bills are valued as determined by an independent pricing service based on methods which include consideration of: yields or prices of securities of comparable quality, coupon, maturity and type; indications as to values from dealers; and general market conditions. Futures and options contracts are valued at the last settled price on the applicable exchange on which that futures and/or options contract trades. (g) Financial Instruments and Fair Value Each Fund discloses the fair value of its investments in accordance with the Financial Accounting Standards Board (“FASB”) fair value measurement and disclosure guidance which requires a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The disclosure requirements establish a fair value hierarchy that distinguishes between: (1) market participant assumptions developed based on market data obtained from sources independent to the Fund (observable inputs); and (2) the Fund’s own assumptions about market participant assumptions developed based on the best information available under the circumstances (unobservable inputs). The three levels defined by the disclosure requirements hierarchy are as follows: Level I: Quoted prices (unadjusted) in active markets for identical assets and liabilities that the reporting entity has the ability to access at the measurement date. Level II: Inputs other than quoted prices included within Level I that are observable for the asset or liability, either directly or indirectly. Level II inputs include the following: quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability, and inputs that are derived principally from or corroborated by observable market data by correlation or other means (market-corroborated inputs). Level III: Unobservable pricing input at the measurement date for the asset or liability. Unobservable inputs shall be used to measure fair value to the extent that observable inputs are not available. In some instances, the inputs used to measure fair value might fall in different levels of the fair value hierarchy. The level in the fair value hierarchy within which the fair value measurement in its entirety falls shall be determined based on the lowest input level that is significant to the fair value measurement in its entirety. Fair value measurements also require additional disclosure when the volume and level of activity for the asset or liability have significantly decreased, as well as when circumstances indicate that a transaction is not orderly. The following tables summarize RISE’s valuation of investments at September 30, 2018 and at June 30, 2018 using the fair value hierarchy: September 30, 2018 (unaudited) Short-Term Purchased Written Futures Total Level I – Quoted Prices $ 60,590,181 a $ 180,062 a $ (42,891 )b $ 872,169 c $ 61,599,521 a – Included in Investments in securities in the Combined Statements of Assets and Liabilities. b – Included in Options Written, at fair value in the Combined Statements of Assets and Liabilities. c – Included in Receivable on open futures contracts in the Combined Statements of Assets and Liabilities. June 30, 2018 (audited) Short-Term Purchased Written Futures Total Level I – Quoted Prices $ 51,144,816 a $ 53,547 a $ (70,664 )b $ (698,426) c $ 50,429,273 a – Included in Investments in securities in the Combined Statements of Assets and Liabilities. b – Included in Options Written, at fair value in the Combined Statements of Assets and Liabilities. c – Included in Payable on open futures contracts in the Combined Statements of Assets and Liabilities. Transfers between levels are recognized at the end of the reporting period. During the three months ended September 30, 2018 and the year ended June 30, 2018, RISE recognized no transfers from Level 1, Level 2 or Level 3. The following table summarizes BDRY’s valuation of investments at September 30, 2018 and at June 30, 2018 using the fair value hierarchy: September 30, 2018 (unaudited) Short-Term Futures Total Level I – Quoted Prices $ 1,219,673 a $ (88,905 )c $ 1,130,768 a – Included in Investments in securities in the Combined Statements of Assets and Liabilities. c – Included in Payable on open futures contracts in the Combined Statements of Assets and Liabilities. June 30, 2018 (audited) Short-Term Futures Total Level I – Quoted Prices $ 1,249,009 a $ 81,680b $ 1,330,689 a – Included in Investments in securities in the Combined Statements of Assets and Liabilities. b – Included in Receivable on open futures contracts in the Combined Statements of Assets and Liabilities. Transfers between levels are recognized at the end of the reporting period. During the three months ended September 30, 2018 and for the period from March 22, 2018 (commencement of investment operations) to June 30, 2018, BDRY recognized no transfers from Level 1, Level 2 or Level 3. The inputs or methodology used for valuing investments are not necessarily an indication of the risk associated with investing in those securities. (h) Investment Transactions and Related Income Investment transactions are recorded on the trade date. All such transactions are recorded on the identified cost basis, and marked to market daily. Unrealized gain/loss on open futures contracts is reflected in Receivable/Payable on open futures contracts in the Combined Statements of Assets and Liabilities and the change in the unrealized gain/loss between periods is reflected in the Combined Statements of Operations. RISE’s discounts on short-term securities purchased are accreted daily and reflected as Interest Income, when applicable, in the Combined Statements of Operations. BDRY’s interest earned on short-term securities and on cash deposited with MacQuarie Futures USA LLC are accrued daily and reflected as Interest Income, when applicable, in the Combined Statements of Operations. (i) Federal Income Taxes Each Fund is registered as a Delaware statutory trust and is treated as a partnership for U.S. federal income tax purposes. Accordingly, the Funds do not expect to incur U.S. federal income tax liability; rather, each beneficial owner is required to take into account their allocable share of the Funds’ income, gain, loss, deductions and other items for the Funds’ taxable year ending with or within the beneficial owner’s taxable year. Management of the Funds has reviewed the open tax years and major jurisdictions and concluded that there is no tax liability resulting from unrecognized tax benefits relating to uncertain income tax positions taken or expected to be taken in future tax returns at September 30, 2018 and June 30, 2018. The Funds are also not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly change in the next twelve months. On an ongoing basis, management will monitor its tax positions taken to determine if adjustments to its conclusions are necessary based on factors including, but not limited to, further implementation of guidance expected from the FASB and on-going analysis of tax law, regulation, and interpretations thereof. The Funds’ federal tax returns are subject to examination by the Internal Revenue Service for a period of three years after they are filed.

Investments [Abstract]
Investments	(3) Investments (a) Short-Term Investments The Funds may purchase U.S. Treasury Bills, agency securities, and other high-credit quality short-term fixed income or similar securities with original maturities of one year or less. A portion of these investments may be used as margin for the Funds’ trading in futures contracts. (b) Accounting for Derivative Instruments In seeking to achieve each Fund’s investment objective, the applicable commodity trading advisor uses a mathematical approach to investing. Using this approach, the applicable commodity trading advisor determines the type, quantity and mix of investment positions that it believes in combination should produce returns consistent with the Fund’s objective. All open derivative positions at September 30, 2018 and at June 30, 2018, as applicable, are disclosed in the Combined Schedules of Investments and the notional value of these open positions relative to the shareholders’ capital of the Funds is generally representative of the notional value of open positions to shareholders’ capital throughout the reporting periods for the Funds. The volume associated with derivative positions varies on a daily basis as the Funds transact in derivative contracts in order to achieve the appropriate exposure, as expressed in notional value, in comparison to shareholders’ capital consistent with the applicable Fund’s investment objective. Following is a description of the derivative instruments used by the Funds during the reporting period, including the primary underlying risk exposures. (c) Futures Contracts The Funds enter into futures contracts to gain exposure to changes in the value of the Benchmark Portfolios. A futures contract obligates the seller to deliver (and the purchaser to accept) the future cash settlement of a specified quantity and type of a treasury futures contract at a specified time and place. The contractual obligations of a buyer or seller of a treasury futures contract may generally be satisfied by making an offsetting sale or purchase of an identical futures contract on the same or linked exchange before the designated date of delivery. Upon entering into a futures contract, the Funds are required to deposit and maintain as collateral at least such initial margin as required by the exchange on which the transaction is affected. The initial margin is segregated as Cash held by broker, as disclosed in the Combined Statements of Assets and Liabilities, and is restricted as to its use. Pursuant to the futures contract, the Funds agree to receive from or pay to the broker an amount of cash equal to the daily fluctuation in value of the futures contract. Such receipts or payments are known as variation margin and are recorded by the Funds as unrealized gains or losses. The Funds will realize a gain or loss upon closing a futures transaction. Futures contracts involve, to varying degrees, elements of market risk (specifically treasury price risk) and exposure to loss in excess of the amount of variation margin. The face or contract amounts reflect the extent of the total exposure the Funds have in the particular classes of instruments. Additional risks associated with the use of futures contracts include imperfect correlation between movements in the price of the futures contracts and the market value of the underlying securities and the possibility of an illiquid market for a futures contract. With futures contracts, there is minimal counterparty risk to the Funds since futures contracts are exchange-traded and the exchange’s clearinghouse, as counterparty to all exchange-traded futures contracts, guarantees the futures contracts against default.

Agreements [Abstract]
Agreements	(4) Agreements (a) Management Fee Each Fund pays the Sponsor a sponsor fee (the “Sponsor Fee”) in consideration of the Sponsor’s advisory services to the Funds. Additionally, each Fund pays its respective commodity trading advisor a license and service fee (the “CTA fee”). Effective January 1, 2018 and later extended on June 1, 2018, the Sponsor has agreed to waive receipt of the Sponsor Fee for RISE and/or assume RISE’s expenses (excluding brokerage fees, interest expense, and extraordinary expenses) so that RISE’s total annual expenses do not exceed 1.00% per annum through September 30, 2019. Further, effective January 1, 2018, RISE’s CTA fee, calculated daily and paid monthly in arrears, was reduced from .50% per annum to .20% per annum of average daily net assets. In addition to the reduction in the expense limit, effective January 1, 2018, RISE’s Sponsor Fee, calculated daily and paid monthly, became the greater of 0.15% of its average daily net assets, or $75,000, and the fees for Principal Financial Officer and Chief Compliance Officer services provided to RISE by the Sponsor were each increased to $25,000 per annum. Certain additional fees paid to the Sponsor for tax return preparation and regulatory reporting fees were also increased. The Sponsor Fee, fees for the Principal Financial Officer and Chief Compliance Officer, and fees for tax return preparation and regulatory reporting reflect the level of fees charged to RISE prior to January 1, 2017. Through December 31, 2017, RISE paid the Sponsor an annual management fee, monthly in arrears, in an amount calculated as the greater of 0.15% of its average daily net assets, or $18,750 effective January 1, 2017. RISE paid an annual fee to Sit, monthly in arrears, in an amount equal to 0.50% of RISE’s average daily net assets, effective January 27, 2016 and through December 31, 2017. As of February 19, 2015, through December 31, 2017, Sit had agreed to waive its CTA fee to the extent necessary, and the Sponsor had agreed to correspondingly assume the remaining expenses of RISE such that RISE’s expenses did not exceed an annual rate of 1.50%, excluding brokerage commissions and interest expense, of the value of the Fund’s average daily net assets (the “RISE Expense Cap”). BDRY pays the Sponsor an annual Sponsor Fee, monthly in arrears, in an amount calculated as the greater of 0.15% of its average daily net assets, or $125,000. BDRY also paid an annual fee to Breakwave, monthly in arrears, in an amount equal to 1.45% of BDRY’s average daily net assets. As of March 22, 2018, Breakwave has agreed to waive its CTA fee to the extent necessary, and the Sponsor has voluntarily agreed to correspondingly assume the remaining expenses of BDRY such that Fund expenses do not exceed an annual rate of 3.50%, excluding brokerage commissions and interest expense, of the value of BDRY’s average daily net assets (the “BDRY Expense Cap,” and together with the RISE Expense Cap, the “Expense Caps”). The assumption of expenses by the Sponsor and waiver of BDRY’s CTA fee are contractual on the part of the Sponsor and Breakwave, respectively. The waiver of RISE’s CTA fees, pursuant to the prior undertaking, amounted to $-0- and $27,123 for the three months ended September 30, 2018 and September 30, 2017, respectively. The waiver of BDRY’s CTA fees, pursuant to the undertaking, amounted to $13,037 for the three months ended September 30, 2018 as disclosed in the Combined Statements of Operations. The Funds currently accrue their daily expenses up to the applicable Expense Cap. At the end of each month, the accrued amount is remitted to the Sponsor as the Sponsor has assumed, and is responsible for the payment of the routine operational, administrative and other ordinary expenses of the Funds in excess of the Funds’ respective Expense Cap, which in the case of RISE, aggregated $30,066 and $10,686 for the three months ended September 30, 2018 and September 30, 2017, respectively, and in the case of BDRY, aggregated $125,190 for the three months ended September 30, 2018, as disclosed in the Combined Statements of Operations. (b) The Administrator, Custodian, Fund Accountant and Transfer Agent Each Fund has appointed U.S. Bank, a national banking association, with its principal office in Milwaukee, Wisconsin, as the custodian (the “Custodian”). Its affiliate, U.S. Bancorp Fund Services, is the Fund accountant (“the Fund accountant”) of the Funds, transfer agent (the “Transfer Agent”) for Fund shares and administrator for the Funds (the “Administrator”). It performs certain administrative and accounting services for the Funds and prepares certain SEC, NFA and CFTC reports on behalf of the Funds. (U.S. Bank and U.S. Bancorp Fund Services are referred to collectively hereinafter as “U.S. Bank”). Effective February 19, 2016, RISE has agreed to pay U.S. Bank 0.05% of assets under management (“AUM”), with a $50,000 minimum annual fee payable for its administrative, accounting and transfer agent services and 0.01% of AUM, with an annual minimum of $4,800 for custody services. RISE paid U.S. Bank $14,191 and $14,040 for the three months ended September 30, 2018 and September 30, 2017, respectively, as disclosed in the Combined Statements of Operations. Effective March 22, 2018, BDRY has agreed to pay U.S. Bank 0.05% of AUM, with a $45,000 minimum annual fee payable for its administrative, accounting and transfer agent services and 0.01% of AUM, with an annual minimum of $4,800 for custody services. BDRY paid U.S. Bank $15,476 for the three months ended September 30, 2018, as disclosed in the Combined Statements of Operations. (c) The Distributor The Funds pay ETFMG Financial LLC. (the “Distributor”), an affiliate of the Sponsor, an annual fee for statutory and wholesaling distribution services and related administrative services equal to the greater of $15,000 or 0.02% of the Funds’ average daily net assets, payable monthly. Pursuant to the respective Marketing Agent Agreement between the Sponsor, each Fund and the Distributor, the Distributor assists the Sponsor and the applicable Fund with certain functions and duties relating to distribution and marketing services to the applicable Fund, including reviewing and approving marketing materials and certain regulatory compliance matters. The Distributor also assists with the processing of creation and redemption orders. RISE incurred $4,410 and $4,408 in distribution and related administrative services for the three months ended September 30, 2018 and September 30, 2017, respectively. BDRY incurred $4,158 in distribution and related administrative services for the three months ended September 30, 2018, as disclosed in the Combined Statements of Operations. RISE also pays the Sponsor an annual fee for wholesale support services equal to 0.1% of RISE’s average daily net assets, payable monthly. BDRY pays the Sponsor an annual fee for wholesale support services of $25,000 plus 0.12% of BDRY’s average daily net assets, payable monthly. RISE incurred $14,756 and $5,424 in wholesale support fees for the three months ended September 30, 2018 and September 30, 2017, respectively. BDRY incurred $7,380 in wholesale support fees for the three months ended September 30, 2018, as disclosed in the Combined Statements of Operations. (d) The Commodity Broker SG Americas Securities, LLC, a Delaware limited liability company, serves as RISE’s clearing broker. MacQuarie Futures USA LLC, a Delaware limited liability company, serves as BDRY’s clearing broker (such clearing broker, together with SG Americas Securities, LLC, the “Commodity Brokers”). In their capacity as clearing broker, the Commodity Brokers execute and clear the Funds’ futures transactions and perform certain administrative services for the Funds. The Funds pay respective brokerage commissions, including applicable exchange fees, National Futures Association (“NFA”) fees, give–up fees, pit brokerage fees and other transaction related fees and expenses charged in connection with trading activities in CFTC regulated investments. Brokerage commissions on futures contracts are recognized on a half-turn basis. The Sponsor does not expect brokerage commissions and fees to exceed 0.09% for RISE, and 0.40% for BDRY, of the net asset value of the applicable Fund for execution and clearing services on behalf of the applicable Fund, although the actual amount of brokerage commissions and fees in any year or any part of any year may be greater. The effects of trading spreads, financing costs associated with financial instruments, and costs relating to the purchase of U.S. Treasury Securities or similar high credit quality short-term fixed-income or similar securities are not included in the foregoing analysis. RISE incurred $16,428 and $8,159 in brokerage commissions and fees for the three months ended September 30, 2018 and September 30, 2017, respectively. BDRY incurred $8,937 in brokerage commissions and fees for the three months ended September 30, 2018, as disclosed in the Combined Statements of Operations. (e) The Trustee Under the respective Amended and Restated Declaration of Trust and Trust Agreement (the “Trust Agreement”) for each Fund, Wilmington Trust Company, the Trustee of each of the Funds (the “Trustee”) serves as the sole trustee of each Fund in the State of Delaware. The Trustee will accept service of legal process on the Funds in the State of Delaware and will make certain filings under the Delaware Statutory Trust Act. Under the respective Trust Agreement for each Fund, the Sponsor has the exclusive management and control of all aspects of the business of the Fund. The Trustee does not owe any other duties to the Fund, the Sponsor or the Shareholders of the Fund. The Trustee has no duty or liability to supervise or monitor the performance of the Sponsor, nor does the Trustee have any liability for the acts or omissions of the Sponsor. RISE incurred $630 and $1,260, in trustee fees for the three months ended September 30, 2018 and September 30, 2017, respectively, which is included in Other Expenses in the Condensed Statements of Operations. BDRY incurred $630 in trustee fees for the three months ended September 30, 2018, which is included in Other Expenses in the Combined Statements of Operations. (f) Routine Offering, Operational, Administrative and Other Ordinary Expenses Effective January 1, 2018, the Sponsor, in accordance with the RISE Expense Cap limitation, paid all of the routine offering, operational, administrative and other ordinary expenses of RISE in excess of 1.00% (excluding brokerage commissions and interest expense) of RISE’s average daily net assets, including, but not limited to, accounting and computer services, the fees and expenses of the Trustee, Administrator, Custodian, Transfer Agent and Distributor, legal and accounting fees and expenses, tax return preparation expenses, filing fees, and printing, mailing and duplication costs. For the three months ended September 30, 2018, the Sponsor paid $30,066 in accordance with the Expense Cap limitation. Through December 31, 2017, the Sponsor, in accordance with RISE’s Expense Cap limitation, paid all of the routine offering, operational, administrative and other ordinary expenses of RISE in excess of 1.50% (excluding brokerage commissions and interest expense) of RISE’s average daily net assets, including, but not limited to, accounting and computer services, the fees and expenses of the Trustee, Administrator, Custodian, Transfer Agent and Distributor, legal and accounting fees and expenses, tax return preparation expenses, filing fees, and printing, mailing and duplication costs. RISE incurred $194,053 and $127,336 for the three months ended September 30, 2018 and September 30, 2017, respectively, in routine offering, operational, administrative or other ordinary expenses. The CTA fee waiver for RISE by Sit expired December 31, 2017. The CTA fee waiver for RISE was $27,123 for the three months ended September 30, 2017. In addition, the assumption of Fund expenses above the RISE Expense Cap By the Sponsor, pursuant to the undertaking then in effect (as discussed in Note 4a), amounted to $10,686 for the three months ended September 30, 2017. The Sponsor, in accordance with the BDRY Expense Cap limitation paid, after the waiver of the CTA fee for BDRY by Breakwave, all of the routine offering, operational, administrative and other ordinary expenses of BDRY in excess of 1.00% (excluding brokerage commissions and interest expense) of BDRY’s average daily net assets, including, but not limited to, accounting and computer services, the fees and expenses of the Trustee, Administrator, Custodian, Transfer Agent and Distributor, legal and accounting fees and expenses, tax return preparation expenses, filing fees, and printing, mailing and duplication costs. BDRY incurred $178,636 during the three months ended September 30, 2018, in routine offering, operational, administrative or other ordinary expenses. The CTA fee waiver for BDRY by Breakwave was $13,037 for the three months ended September 30, 2018. In addition, the assumption of Fund expenses above the BDRY Expense Cap by the Sponsor, pursuant to the undertaking (as discussed in Note 4a), amounted to $125,190 for the three months ended September 30, 2018. (g) Organizational and Offering Costs Expenses incurred in connection with organizing RISE and up to the offering of its Shares upon commencement of its investment operations on February 19, 2015, were paid by the Sponsor and Sit without reimbursement. Expenses incurred in connection with organizing BDRY and up to the offering of its Shares upon commencement of its investment operations on March 22, 2018, were paid by the Sponsor and Breakwave without reimbursement. Accordingly, all such expenses are not reflected in the Statements of Operations. The Funds will bear the costs of their continuous offerings of Shares and ongoing offering expenses. Such ongoing offering costs will be included as a portion of the Routine Offering, Operational, Administrative and Other Ordinary Expenses. These costs will include registration fees for regulatory agencies and all legal, accounting, printing and other expenses associated therewith. These costs will be accounted for as a deferred charge and thereafter amortized to expense over twelve months on a straight-line basis or a shorter period if warranted. For the three months ended September 30, 2018 and September 30, 2017, respectively, RISE did not incur such expenses. For the three months ended September 30, 2018, BDRY did not incur such expenses. (h) Extraordinary Fees and Expenses The Fund will pay all extraordinary fees and expenses, if any. Extraordinary fees and expenses are fees and expenses which are nonrecurring and unusual in nature, such as legal claims and liabilities, litigation costs or indemnification or other unanticipated expenses. Such extraordinary fees and expenses, by their nature, are unpredictable in terms of timing and amount. For the three months ended September 30, 2018 and September 30, 2017, respectively, RISE did not incur such expenses. For the three months ended September 30, 2018, BDRY did not incur such expenses.

Creations and Redemptions [Abstract]
Creations and Redemptions	(5) Creations and Redemptions Each Fund issues and redeems Shares from time to time, but only in one or more Creation Baskets. A Creation Basket is a block of 25,000 Shares (50,000 Shares prior to August 17, 2018) of each Fund. Baskets may be created or redeemed only by Authorized Participants. Except when aggregated in Creation Baskets, the Shares are not redeemable securities. Retail investors, therefore, generally will not be able to purchase or redeem Shares directly from or with each Fund. Rather, most retail investors will purchase or sell Shares in the secondary market with the assistance of a broker. Thus, some of the information contained in these Notes to Financial Statements – such as references to the Transaction Fee imposed on creations and redemptions – is not relevant to retail investors. (a) Transaction Fees on Creation and Redemption Transactions In connection with orders to create and redeem one or more Creation Baskets, an Authorized Participant is required to pay a transaction fee, or AP Transaction Fee, of $500 per order, which goes directly to the Custodian. The AP Transaction Fees are paid by the Authorized Participants and not by the Funds.

Risk

Risks and Uncertainties [Abstract]
Risk	(6) Risk (a) Investment Related Risk The NAV of RISE’s shares relates directly to the value of the U.S. treasuries, cash and cash equivalents held by RISE and the portfolio’s negative effective duration established and maintained through RISE’s investment in Treasury Instruments. Fluctuations in the prices of these assets could materially adversely affect the value and performance of an investment in RISE’s shares. Past performance is not necessarily indicative of future results; all or substantially all of an investment in RISE could be lost. Investments in debt securities typically decrease in value when interest rates rise, however, RISE attempts to maintain a portfolio with a negative effective duration and therefore anticipates that an increase in interest rates may increase RISE’s value, and a decrease in rates may lower RISE’s value. The NAV of RISE’s shares relates directly to the value of U.S. Treasuries and Treasury Instruments held by RISE which are materially impacted by interest rate movements. The magnitude of the impact on value from a change in interest rates is often greater for longer-term fixed income than shorter-term securities. Interest rates have been near historic lows since the market events of 2008 and may remain low. Interest rate movements are heavily influenced by the action of the Board of Governors of the Federal Reserve System and other central banks. Their actions are based on judgments and policies which involve numerous political and economic factors which are unpredictable. Recent interest rate and monetary policies have been unprecedented and may continue to be so. RISE attempts to track a portfolio benchmark. The performance of RISE may not closely track the performance of the RISE Benchmark Portfolio for a variety of reasons. For example, RISE incurs operating expenses and portfolio transaction costs not incurred by the benchmark. RISE is also required to manage cash flows and may experience operational inefficiencies the benchmark does not. In addition, RISE may not be fully invested in the contents of its benchmark at all times or may hold securities not included in its benchmark. RISE invests in Treasury Instruments and U.S. treasuries with exposure to different maturity dates. Generally, RISE’s exposure to securities with maturities of 2 and 5 years will be greater than its exposure to securities with maturities of 10 years. Interest rates do not change uniformly for U.S. Treasuries of different maturities and therefore if interest rates rise, the investment performance of RISE will be impacted by RISE’s current maturity exposure which may be different from the expectations of the Sponsor and investors in RISE. At any time, RISE’s maturity exposure may not be optimal with respect to a movement in interest rates which would negatively impact performance. The NAV of BDRY’s shares relates directly to the value of the futures portfolio, cash and cash equivalents held by BDRY. Fluctuations in the prices of these assets could materially adversely affect the value and performance of an investment in BDRY’s shares. Past performance is not necessarily indicative of future results; all or substantially all of an investment in BDRY could be lost. The NAV of BDRY’s shares relates directly to the value of futures investments held by BDRY which are materially impacted by fluctuations in changes in spot charter rates. Charter rates for dry bulk vessels are volatile and have declined significantly since their historic highs and may remain at low levels or decrease further in the future. Futures and options contracts have expiration dates. Before or upon the expiration of a contract, BDRY may be required to enter into a replacement contract that is priced higher or that have less favorable terms than the contract being replaced (see “Negative Roll Risk,” below). The Freight Futures market settles in cash against published indices, so there is no physical delivery against the futures contracts. Similar to other futures contracts, the Freight Futures curve shape could be either in “contango” (where the futures curve is upward sloping with next futures price higher than the current one) or “backwardation” (where each the next futures price is lower than the current one). Contango curves are generally characterized by negative roll cost, as the expiring contract value is lower that the next prompt contract value, assuming the same lot size. That means there could be losses incurred when the contracts are rolled each period and such losses are independent of the Freight Futures price level. (b) Liquidity Risk In certain circumstances, such as the disruption of the orderly markets for the futures contracts or Financial Instruments in which the Funds invest, the Funds might not be able to dispose of certain holdings quickly or at prices that represent what the market value may have been in an orderly market. Futures and option positions cannot always be liquidated at the desired 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 can also make it difficult to liquidate a position. The large size of the positions that the Funds may acquire increases the risk of illiquidity both by making its positions more difficult to liquidate and by potentially increasing losses while trying to do so. Such a situation may prevent the Funds from limiting losses, realizing gains or achieving a high correlation with the applicable Benchmark Portfolio.

Indemnifications [Abstract]

Net Asset Value And Financial Highlights [Abstract]
Net Asset Value and Financial Highlights	(10) Net Asset Value and Financial Highlights The Funds are presenting, as applicable, the following net asset value and financial highlights related to investment performance for a Share outstanding throughout the three months ended September 30, 2018 and September 30, 2017. The net investment income and total expense ratios are calculated using average net assets. The net asset value presentation is calculated by dividing each Fund’s net assets by the average daily number of Shares outstanding. The net investment income (loss) and expense ratios have been annualized. The total return is based on the change in net asset value and market value of the Shares during the period. An individual investor’s return and ratios may vary based on the timing of their transactions in Fund Shares.

New Accounting Pronouncements	(11) New Accounting Pronouncements In October 2016, the Securities and Exchange Commission (SEC) issued Final Rule Release No. 33-10231, Investment Company Reporting Modernization (the Release). The Release calls for adoption of new rules and forms as well as amendments to its rules and forms to modernize the reporting and disclosure of information by registered investment companies. The SEC is adopting amendments to Regulation S-X, which will require standardized, enhanced disclosure about derivatives in investment company financial statements, as well as other amendments. The updates to Regulation S-X were effective August 1, 2017 and may result in additional disclosure relating to the presentation of derivatives and certain other financial instruments. These updates have had no impact on the Funds’ net assets or results of operations. In November 2016, FASB issued a new Accounting Standards Update No. 2016-18, “Statement of Cash Flows (Topic 230 Restricted Cash, a consensus of the FASB’s Emerging Issues Task Force”

Summary of Significant Accounting Policies (Policies)	3 Months Ended

Accounting Policies [Abstract]
Basis of Accounting	(a) Basis of Accounting The accompanying financial statements of the Funds have been prepared in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”). Each Fund qualifies as an investment company for financial reporting purposes under Topic 946 of the Accounting Standard Codification of U.S. GAAP. The accompanying combined financial statements are unaudited, but in the opinion of management, contain all adjustments (which include normal recurring adjustments) considered necessary to present fairly the financial statements. These interim financial statements should be read in conjunction with RISE’s annual report on Form 10-K for the year ended June 30, 2018, RISE’s prospectus dated January 22, 2018 (the “RISE Prospectus”) and BDRY’s prospectus dated March 13, 2018 (the “BDRY Prospectus,” and together with the RISE Prospectus, the “Prospectuses”). Interim period results are not necessarily indicative of results for a full-year period.
Use of Estimates	(b) Use of Estimates The preparation of the combined financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the combined financial statements and accompanying notes. Actual results could differ from those estimates. There were no significant estimates used in the preparation of the combined financial statements.
Cash	(c) Cash Cash, when shown in the Combined Statements of Assets and Liabilities, represents non-segregated cash with the custodian and does not include short-term investments.
Cash Held by Broker	(d) Cash Held by Broker Sit is registered as a “commodity trading advisor” and acts as such for RISE. Breakwave is registered as a “commodity trading advisor” and acts as such for BDRY. Each Fund’s arrangement with its respective FCM requires the Fund to meet its variation margin requirement related to the price movements, both positive and negative, on futures contracts held by the Fund by keeping cash on deposit with the Commodity Brokers (as defined below). These amounts are shown as Segregated cash held by broker in the Combined Statements of Assets and Liabilities. The Funds deposit cash or United States Treasury Obligations, as applicable, with their respective FCM subject to the CFTC regulations and various exchange and broker requirements. The combination of the Funds’ deposits with their respective FCM of cash and United States Treasury Obligations, as applicable, and the unrealized gain or loss on open futures contracts (variation margin) represents the Funds’ overall equity in their respective brokerage trading account. The Funds use their cash held by their respective FCM to satisfy variation margin requirements. The Funds earn interest on their cash deposited with their respective FCM and interest income is recorded on the accrual basis.
Final Net Asset Value for Fiscal Period	e) Final Net Asset Value for Fiscal Period The calculation time of each Fund’s final net asset value for creation and redemption of Fund shares for the three months ended September 30, 2018 and 2017 was at 4:00 p.m. Eastern Time on September 28, 2018 and September 29, 2017, respectively. Although the Funds’ shares may continue to trade on secondary markets subsequent to the calculation of the final NAV, the 4:00 p.m. Eastern Time represented the final opportunity to transact in creation or redemption baskets for the three months ended September 30, 2018 and 2017. Fair value per share is determined at the close of the NYSE Arca. For financial reporting purposes, each Fund values its investment positions based upon the final closing price in their primary markets. Accordingly, the investment valuations in these financial statements differ from those used in the calculations of the Funds’ final creation/redemption NAVs at September 28, 2018 and June 30, 2018.
Investment Valuation	(f) Investment Valuation Short-term investments, excluding U.S. Treasury Bills, are carried at amortized cost, which approximates fair value. U.S. Treasury Bills are valued as determined by an independent pricing service based on methods which include consideration of: yields or prices of securities of comparable quality, coupon, maturity and type; indications as to values from dealers; and general market conditions. Futures and options contracts are valued at the last settled price on the applicable exchange on which that futures and/or options contract trades.
Financial Instruments and Fair Value	(g) Financial Instruments and Fair Value Each Fund discloses the fair value of its investments in accordance with the Financial Accounting Standards Board (“FASB”) fair value measurement and disclosure guidance which requires a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The disclosure requirements establish a fair value hierarchy that distinguishes between: (1) market participant assumptions developed based on market data obtained from sources independent to the Fund (observable inputs); and (2) the Fund’s own assumptions about market participant assumptions developed based on the best information available under the circumstances (unobservable inputs). The three levels defined by the disclosure requirements hierarchy are as follows: Level I: Quoted prices (unadjusted) in active markets for identical assets and liabilities that the reporting entity has the ability to access at the measurement date. Level II: Inputs other than quoted prices included within Level I that are observable for the asset or liability, either directly or indirectly. Level II inputs include the following: quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability, and inputs that are derived principally from or corroborated by observable market data by correlation or other means (market-corroborated inputs). Level III: Unobservable pricing input at the measurement date for the asset or liability. Unobservable inputs shall be used to measure fair value to the extent that observable inputs are not available. In some instances, the inputs used to measure fair value might fall in different levels of the fair value hierarchy. The level in the fair value hierarchy within which the fair value measurement in its entirety falls shall be determined based on the lowest input level that is significant to the fair value measurement in its entirety. Fair value measurements also require additional disclosure when the volume and level of activity for the asset or liability have significantly decreased, as well as when circumstances indicate that a transaction is not orderly. The following tables summarize RISE’s valuation of investments at September 30, 2018 and at June 30, 2018 using the fair value hierarchy: September 30, 2018 (unaudited) Short-Term Purchased Written Futures Total Level I – Quoted Prices $ 60,590,181 a $ 180,062 a $ (42,891 )b $ 872,169 c $ 61,599,521 a – Included in Investments in securities in the Combined Statements of Assets and Liabilities. b – Included in Options Written, at fair value in the Combined Statements of Assets and Liabilities. c – Included in Receivable on open futures contracts in the Combined Statements of Assets and Liabilities.

Transfers between levels are recognized at the end of the reporting period. During the three months ended September 30, 2018 and the year ended June 30, 2018, RISE recognized no transfers from Level 1, Level 2 or Level 3. The following table summarizes BDRY’s valuation of investments at September 30, 2018 and at June 30, 2018 using the fair value hierarchy: September 30, 2018 (unaudited) Short-Term Futures Total Level I – Quoted Prices $ 1,219,673 a $ ( 88,905 )c $ 1,130,768 a – Included in Investments in securities in the Combined Statements of Assets and Liabilities. c – Included in Payable on open futures contracts in the Combined Statements of Assets and Liabilities.

Transfers between levels are recognized at the end of the reporting period. During the three months ended September 30, 2018 and for the period from March 22, 2018 (commencement of investment operations) to June 30, 2018, BDRY recognized no transfers from Level 1, Level 2 or Level 3. The inputs or methodology used for valuing investments are not necessarily an indication of the risk associated with investing in those securities.
Investment Transactions and Related Income	(h) Investment Transactions and Related Income Investment transactions are recorded on the trade date. All such transactions are recorded on the identified cost basis, and marked to market daily. Unrealized gain/loss on open futures contracts is reflected in Receivable/Payable on open futures contracts in the Combined Statements of Assets and Liabilities and the change in the unrealized gain/loss between periods is reflected in the Combined Statements of Operations. RISE’s discounts on short-term securities purchased are accreted daily and reflected as Interest Income, when applicable, in the Combined Statements of Operations. BDRY’s interest earned on short-term securities and on cash deposited with MacQuarie Futures USA LLC are accrued daily and reflected as Interest Income, when applicable, in the Combined Statements of Operations.
Federal Income Taxes	(i) Federal Income Taxes Each Fund is registered as a Delaware statutory trust and is treated as a partnership for U.S. federal income tax purposes. Accordingly, the Funds do not expect to incur U.S. federal income tax liability; rather, each beneficial owner is required to take into account their allocable share of the Funds’ income, gain, loss, deductions and other items for the Funds’ taxable year ending with or within the beneficial owner’s taxable year. Management of the Funds has reviewed the open tax years and major jurisdictions and concluded that there is no tax liability resulting from unrecognized tax benefits relating to uncertain income tax positions taken or expected to be taken in future tax returns at September 30, 2018 and June 30, 2018. The Funds are also not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly change in the next twelve months. On an ongoing basis, management will monitor its tax positions taken to determine if adjustments to its conclusions are necessary based on factors including, but not limited to, further implementation of guidance expected from the FASB and on-going analysis of tax law, regulation, and interpretations thereof. The Funds’ federal tax returns are subject to examination by the Internal Revenue Service for a period of three years after they are filed.
